full automatic stone polishing grinding machine plc control system production line exporting factory on sale business

This system is a multi head continuous mill operating system specially developed according to the processing characteristics of stone plate. The system adopts advanced touch human-machine interface, which can monitor each working condition and facilitate data setting and action operation.

System operation is divided into automatic operation and automatic operation. When the "manual automatic" knob on the current main control panel points to "manual" (see Fig. 1), the machine tool can be manually operated and controlled, that is, the forward and reverse movement of the machine tool belt and the swing of the crossbeam can be operated with the manual knob. (in the manual mode, press the crossbeam swing to start, and the crossbeam can swing within the range of front and rear travel switch by itself). In addition, each grinding head is equipped with its own manual and automatic operation knob. For example, when 1 grinding head is in the manual position (see Figure 1), 1 grinding head rotates and descends. If the manual automatic knob points to "automatic", the grinding head starts to participate in the automatic operation of the equipment, and the grinding head is controlled by the automatic control system to start and stop, and automatically rises and falls according to the stone slab.

When the "manual and automatic" knob on the current main control panel points to "automatic", press the start button again, and each grinding head will start in sequence (the knob above the single grinding head must point to the "automatic" position). After the start in sequence, the crossbeam will start to swing, and then press the start button of the conveyor belt, and the conveyor belt will start to move. At this time, the stone slab can be placed. In the process of automatic operation, each grinding head can be manually and automatically switched at any time, or the conveyor belt and crossbeam can be suspended by pressing the "pause" button, and the operation can be resumed by pressing the "pause" button again.

(I) working environment of equipment:

The design of the plant where the equipment is placed requires ventilation and noise reduction; there must be measures to supply clean water and blowdown; there should be a sewage treatment system that can treat the waste water generated by the whole production line, separate the waste (stone powder, stone, abrasive slag) from the water, and realize the recycling of water.

(II) basic treatment:

1. The size and location of equipment foundation shall meet the requirements of foundation drawing provided by the company, and the foundation quality shall meet the requirements of code for construction and acceptance of concrete engineering (gbj10-65).

2. The foundation must be completed half a month before the equipment installation.

3. Foundation construction method:

1) professional construction personnel shall determine the foundation structure according to the local geological conditions;

2) determine the processing direction and direction of the equipment, arrange the specific location of the production line according to the requirements of the foundation drawing, and determine the basic size range of the equipment;

3) excavate the pit to the required depth, level and compact the pit bottom, and fill the lime soil layer by layer to the required depth as required;

4) fix the formwork, arrange and fix the formwork according to the required position of the foundation drawing;

5) one time grouting shall be carried out according to the mark and size required by the foundation drawing. After solidification, the formwork shall be removed and maintained;

6) before solidification, the level of each base plate shall be calibrated, and the horizontal error of the base plate of the whole machine must be within ± 2.0mm;

7) wait for equipment installation.

(III) installation and commissioning

A. equipment installation

The equipment shall be hoisted safely by crane (or forklift), and the equipment shall be moved slowly to the required position to avoid shaking and collision; during hoisting, ensure that there are no obstacles within the moving range of the equipment, and it is forbidden to stand below! After the equipment is in place, adjust the adjusting bolts of the worktable, and measure the level of the worktable with a spirit level to make the levelness error of the worktable ≤ 0.15mm/1000mm. The length of the whole worktable should be measured at least at two positions;

Check whether both ends of the driving drum and driven drum of the workbench are in the same plane with the upper surface of the workbench (they have been adjusted in the factory, mainly checking whether there is any change in the lifting and transportation process);

Connect the main cable, check whether the wiring is loose, and protect the main cable; the whole machine is grounded safely.

Connect the water source to the water inlet pipe and fix it well without water leakage; connect the air source, add a proper amount of lubricating oil into the air source treatment triplet and adjust the oil drop correctly;

Inject a proper amount of lubricating oil into the oil pool of the supporting foot guide rail, fix the cover of the oil pool, and the oil height is better at the bottom of the rack tooth height.

Install abrasive properly and lock it

B. preparation before commissioning:

According to the introduction of main technical parameters, check whether the electricity, water and gas required are ready:

1. Check whether the electrical wiring is correct and firm;

2. Overall inspection shall be carried out for the main engine and accessories, and all fasteners shall be fastened and reliable;

3. When the air supply is not powered on, each grinding head shall be raised to the upper limit;

4. Whether the beam swing limit device is suitable;

5. Each lubricating part shall be filled with lubricating oil and grease as required;

6. Check the tightness of the conveyor belt and the transmission triangle belt of each grinding head;

C. no load test run and adjustment

The no-load test run shall be carried out in accordance with the principle of "from components to components, then to the whole machine; from manual to automatic; from low speed to high speed".

1. Pressure adjustment of main engine air source

Check the air supply pressure to make the air supply pressure of the triplet reach 0.5 ~ 0.6MPa; check and adjust the valves of the air circuit until the lifting speed of each grinding head is uniform.

2. Adjustment of grinding head falling pressure

The equipment is designed for back pressure pneumatic lowering control. Before starting the equipment, manually adjust the pressure value of each grinding head to 0.1MPa or left to the minimum, and then adjust it according to the actual pressure of each grinding head. Generally, the pressure value of the pressure gauge corresponding to the grinding head is between 0.1 and 0.5MPa, and the pressure of the grinding head of different plate materials and different positions is also different.

It is recommended that the maximum working pressure of each grinding head of the equipment is not more than 0.5MPa.

3. Adjustment of throttle valve

When the grinding head falls too fast or too slowly, the throttle valve of two cylinders corresponding to each grinding head shall be adjusted, and the throttle valve knob shall be rotated clockwise to slow down the falling speed, and vice versa.

4. Adjustment of conveyor belt

By adjusting the adjusting bolts at both ends of the driven drum end, the conveyor belt is tightened or loosened, so that the tightening degree on both sides of the conveyor belt is approximately the same and does not make it offset.

1) when conveying the belt, adjust and lengthen the loose end to increase the distance between the roller at this end and the workbench.

Warning remember, do not adjust one end of the driving roller (reducer) generally. Only when the conveyor belt is biased to different sides on two rollers, one end of the driving roller needs to be slightly adjusted (it has been adjusted before delivery).

Warning the adjustment of the conveyor belt will take a long time to adjust to the ideal state, so the rotation angle of each adjustment bolt should not be too large, 15 ° ~ 30 ° is appropriate.

Note that if the conveyor belt is too loose, it will not transmit the due power, and will produce slip, which will lead to overheating or even damage of the conveyor belt; if the conveyor belt is too tight, it will accelerate the stress on the shaft and bearing, and in serious cases, it will break the shaft. If the equipment is not used for a long time, the conveyor belt must be loosened and cleaned.

(IV) adjustment of trial operation of plate feeding

1. Check

1) the test can be started only when the automatic electrical control is out of control to ensure safety;

2) confirm that there is no fault in mechanical operation, all parts are normal and all water pipe joints are free of water leakage;

3) the electrical system is in manual state.

4) test operation: raise the grinding head, run at idle, and check the operation.

2. Trial operation of plate feeding

1) adjustment of swing amplitude

After entering the plate, check the swing of the grinding head. The requirements for swing amplitude are as follows:

L: slate width

N: the distance from the edge of abrasive to the stone plate n = 20 ~ 40mm;

Z. swing width

M: abrasive thickness

E: plate thickness

The swing amplitude of the crossbeam is controlled by the travel switch in the front (left) part of the mill. To change the swing amplitude of the crossbeam, the position of the inductive iron block of the switch can be adjusted, and the inertia travel brought by the speed shall be considered.

2) matching of grinding disc abrasives

For the process matching of abrasive disc, please refer to the relevant information for the best grinding and polishing effect.

Pay attention to adjust the swing speed of the crossbeam and the rotation speed of the drum according to the width of the plate for grinding.
