Description

Technical Field

[0001] The present invention relates to the technical field of dipping glaze machines, and particularly to a dipping glaze machine for large-sized ceramic products. Background Art

[0002] In the actual ceramic production activities, there is no automated equipment for glazing large-sized ceramic products. Most of the work is done by workers holding the products by hand, putting the products into the glaze slurry pool for soaking, and at the same time turning them in the glaze pool so that the glaze slurry adheres to all surfaces of the products. After soaking for a certain time, the products are taken out of the glaze pool to complete the glazing process. In this process, the workers need to hold the products throughout. Since the average weight of large-sized ceramic products is about 8 kg, the labor intensity of the workers is relatively high. At the same time, they also need to judge the soaking time based on experience. The product quality is directly related to the technical level of the workers, which is not conducive to standardized production. In addition, when large mechanical clamps are used to clamp large-sized ceramic products, they are easily damaged and break the large-sized ceramic products, resulting in a large number of defective products; the glaze slurry in the glaze pool is prone to precipitation, which greatly affects the glazing effect of large-sized ceramic products; and the function of automatic cleaning cannot be achieved. Therefore, it is extremely urgent to design a dipping glaze machine for large-sized ceramic products. Summary of the Invention

[0016] (III) Beneficial effects

[0017] The present invention provides a dipping glazing machine for large-sized ceramic products, which has the following beneficial effects:

[0018] 1. The dipping glazing machine for large-sized ceramic products of the present invention solves the technical problems that there is no automated equipment for glazing large-sized ceramic products and most of the work is manually operated, thereby greatly improving the work efficiency, saving labor costs, and also solving the technical problems of difficult transportation and dipping of large-sized ceramic products.

[0019] 2. The dipping glazing machine for large-sized ceramic products of the present invention uses a vacuum generator, a vacuum suction pipe, and a suction cup platform to hold the workpiece to be processed. Since ceramic products are fragile and easily damaged by mechanical jigs, the advantages of this design are that on the one hand, it can avoid damaging or destroying the workpiece when clamping the workpiece with a large mechanical jig, and on the other hand, it can also avoid using a large jig to save equipment space, reduce costs, facilitate glazing, and enable complete glazing of large-sized ceramic products.

[0020] 3. The present invention also improves the structure of the glaze pool. The glaze inlet pipe is laid at the bottom of the glaze inlet area. After the glaze slurry enters the glaze pool from the glaze inlet on the glaze inlet pipe, it will cause the glaze slurry to flow, thereby stirring the glaze slurry in the glaze pool and delaying the precipitation of the glaze slurry. A glaze slurry liquid level control structure is also provided on the glaze pool. When the glaze slurry in the glaze inlet area reaches the height of the notch, it flows into the filtration pool from the notch. The glaze slurry will flow from the notch on the filtration pool into the glaze return area, and large particles will be intercepted and filtered by the filtration pool. After the glaze slurry in the glaze return area reaches the height of the glaze return port, it flows into the glaze bucket from the glaze return port and is recycled and pumped again by the glaze pump, so that the glaze slurry is always in a flowing state, which can greatly delay the precipitation of the glaze slurry and improve the glazing effect.

[0021] 4. The dipping glazing machine for large-sized ceramic products of the present invention adopts a reasonable spatial layout design of the lifting structure, the flipping structure, and the cleaning structure. On the one hand, it can not only make the structure compact and reduce the floor space occupied by the structure, but also shorten the entire process of dipping glazing large-sized ceramic products and workpiece transportation, improve work efficiency. In addition, a smaller number of cylinders and motors can be used to achieve multiple processes such as flipping workpieces, dipping up and down, and cleaning.

[0022] 5. The stepping motor of the large-piece ceramic product dipping machine of the present invention can drive the lifting platform to complete the lifting action according to the PLC program in the electric control box. The flipping structure is installed on the lifting platform, and a reduction motor is installed on the flipping structure. The reduction motor controls the flipping platform to flip. There is an angle position sensor on the flipping platform, and the PLC program in the electric control box controls the flipping platform to complete flips at various angle positions, so as to meet the dipping requirements of ceramic products of various shapes and sizes, greatly improving its scope of application.

[0023] 6. The sewage squeezed out from the scrubbing sponge of the present invention falls into the squeezing water tank and then enters the sedimentation tank through a pipeline. After the sewage is sedimented in the sedimentation tank, the water after sedimentation treatment comes to the water storage tank of the cleaning water tank again through a sewage pump, realizing the process of sewage sedimentation filtration and recycling.

[0024] 7. A sewage discharge port is also provided on the side of the glaze pool 4 of the present invention, and the glaze pool can be conveniently cleaned through the sewage discharge port.

The lifting structure 8 includes a stepping motor 31, a column 25, and a lifting platform 28. The stepping motor 31 is installed at the top of the column 25. The stepping motor 31 is connected to a ball screw through a coupling. A lifting platform 28 is installed on the screw. The lifting platform 28 is fixed to the flipping structure 7. The flipping structure 7 includes a vacuum suction pipe 30, a suction cup platform 29, a reduction motor 26, a synchronous belt device, and a vacuum generator. The rotating shaft of the reduction motor 26 is connected to the rotating shaft of the vacuum suction pipe 30 through the synchronous belt device. The suction cup platform 29 is fixed to the vacuum suction pipe 30. The interior of the vacuum suction pipe 30 is hollow. The vacuum generator is connected to the suction holes on the suction cup platform 29 through the vacuum suction pipe 30. The glaze circulation system is connected to the glaze pool 4. The glaze pool 4 and the cleaning structure 6 are fixed to the front side of the frame 1. The cleaning structure 6 includes a mouth wiping alignment cylinder 10, a swing table cylinder 11, a wiping surface alignment cylinder 12, a high and low position cylinder 13, and a wiping surface driving motor 14. The rotating shaft of the swing table cylinder 11 is fixed to the wiping surface alignment cylinder 12. The wiping surface alignment cylinder 12 is fixed to the high and low position cylinder 13. The wiping surface driving motor 14 is fixed to the high and low position cylinder 13. The rotating shaft of the wiping surface driving motor 14 is fixed to a wiping surface sponge 21. The mouth wiping alignment cylinder 10 is fixed below the swing table cylinder 11. The lifting platform 28 is connected to the guide rail on the column 25 through a slider. The electric control box 9 is arranged on the side of the frame 1. The glaze circulation system, the lifting structure 8, the flipping structure 7, the cleaning structure 6, the sewage treatment structure, etc. are controlled through the electric control box 9. The mouth wiping alignment cylinder 10 is connected to a mouth wiping sponge 22.

[0036] The sewage treatment structure includes a sewage pump 17, a sedimentation tank 16, and a cleaning sink 15. The cleaning sink 15 is installed on one side of the cleaning structure 6. The cleaning sink 15 is connected to the sedimentation tank 16 through a pipeline. The sedimentation tank 16 is connected to the sewage pump 17.

[0037] The cleaning sink 15 includes a water storage tank 24, a water squeezing tank, and a water squeezing platform 23. A plurality of grooves are formed on the water squeezing platform 23. The water squeezing platform 23 is installed above the water squeezing tank. The water squeezing tank is connected to the sedimentation tank 16 through a pipeline. The sewage pump 17 is connected to the water storage tank 24 through a pipeline.

[0038] Working principle: First, turn on the vacuum generator. The vacuum generator extracts vacuum through the vacuum suction pipe 30 and tightly sucks the workpiece to be processed (the workpiece to be processed can be a large ceramic product) placed on the suction cup platform 29. After the workpiece is placed, the flipping structure works. The reduction motor 26 drives the vacuum suction pipe 30 to rotate through the synchronous belt device, thereby flipping the suction cup platform 29 and the workpiece to be processed. Then, the lifting structure 8 works. The stepping motor 31 drives the ball screw to rotate through the coupling, thereby driving the lifting platform 28 to descend or ascend on the column 25, and further driving the flipping structure 7, the suction cup platform 29, and the workpiece to be processed to descend or ascend together, and the glazing or unglazing actions during the product glazing process can be completed.

[0039] After glazing is completed, a part of the glaze slurry remains on the suction cup platform. The cleaning structure works. The swing table cylinder 11 is started, and the rotating shaft of the swing table cylinder 11 rotates clockwise by 90 degrees, driving the friction surface alignment cylinder 12 fixed to the rotating shaft of the swing table cylinder to rotate clockwise by 90 degrees, thereby driving the high-low position cylinder 13, the friction surface driving motor 14, and the friction surface sponge 21 to rotate clockwise by 90 degrees. Then, the piston of the friction surface alignment cylinder 12 extends, moving the high-low position cylinder 13, the friction surface driving motor 14, and the friction surface sponge 21 above the suction cup platform. Then, the piston of the high-low position cylinder 13 extends, driving the friction surface driving motor 14 and the friction surface sponge 21 to move downward, moving the friction surface driving motor 14 to the low position, making the friction surface sponge 21 contact the suction cup platform 29. Then, start the friction surface driving motor 14. The friction surface driving motor 14 drives the friction surface sponge 21 to perform a circular motion to wipe the remaining glaze slurry on the suction cup platform. After cleaning the entire suction cup platform, the piston of the high-low position cylinder 13 retracts, the piston of the friction surface alignment cylinder 12 retracts, and the driving motor 14 comes above the wiping port sponge 22. The piston of the high-low position cylinder 13 extends, making the friction surface sponge 21 contact the wiping port sponge 22. After that, the friction surface driving motor 14 works, driving the friction surface sponge 21 to rotate, and cleaning the wiping port sponge 22 with the friction surface sponge 21.

[0040] After that, the piston of the high-low position cylinder 13 retracts, and the swing table cylinder 11 rotates counterclockwise by 90 degrees. At this time, the extending direction of the piston of the friction surface alignment cylinder 12 points to the cleaning water tank. After the piston of the friction surface alignment cylinder 12 extends, it drives the high-low position cylinder 13, the friction surface driving motor 14, and the friction surface sponge 21 above the cleaning water tank. Then, the piston of the high-low position cylinder 13 extends, inserting the friction surface sponge 21 into the water storage tank 24 of the cleaning water tank. After the friction surface sponge 21 is filled with water, the piston of the high-low position cylinder 13 retracts, and the piston of the friction surface alignment cylinder 12 retracts a certain distance, positioning the high-low position cylinder 13 and the friction surface sponge 21 above the water squeezing platform 23. Then, the piston of the high-low position cylinder 13 extends, pressing the friction surface sponge 21 on the water squeezing platform 23 of the cleaning water tank to squeeze out the water in the friction surface sponge 21, completing the cleaning work of the friction surface sponge 21 and waiting for the next cleaning task.

[0041] The sewage squeezed out from the scrubbing sponge falls into the squeezing water tank and then enters the sedimentation tank 16 through a pipeline. After the sewage is sedimented in the sedimentation tank, the water after sedimentation treatment comes to the water storage tank of the cleaning water tank again through a sewage pump, realizing the process of sewage sedimentation filtration and recycling.

[0042] In another embodiment of the present invention, the structure of the glaze tank 4 is also improved. An inlet glaze pipe 19, a filtration tank 5, and a return glaze port 18 are further provided inside the glaze tank 4. The glaze tank 4 is divided into an inlet glaze area and a return glaze area by a partition board. The inlet glaze pipe 19 is laid at the bottom of the inlet glaze area, and a plurality of inlet glaze ports are provided on the inlet glaze pipe 19. The filtration tank 5 is installed above the return glaze area, and a notch is opened on the partition board close to the filtration tank 5 (this structure is a glaze slurry liquid level control structure). The return glaze port 18 is arranged in the return glaze area, and both the return glaze port 18 and the inlet glaze pipe are connected to the glaze circulation system.

[0043] The glaze circulation system includes a glaze pump 2 and a glaze bucket 3. The glaze pump 2 is arranged inside the glaze bucket 3, and the glaze pump 2 is connected to the inlet glaze pipe. The glaze bucket 3 is connected to the return glaze port 18.

[0044] During operation, the glaze pump 2 pumps the glaze slurry in the glaze bucket 3 into the inlet glaze pipe 19. Since the inlet glaze pipe 19 is laid at the bottom of the inlet glaze area, after the glaze slurry enters the glaze tank 4 from the inlet glaze ports on the inlet glaze pipe 19, it will cause the glaze slurry to flow, thereby stirring the glaze slurry in the glaze tank and delaying the precipitation of the glaze slurry.

[0045] When the glaze slurry in the inlet glaze area reaches the height of the notch, it flows into the filtration tank 5 from the notch. The glaze slurry will flow from the notch on the filtration tank 5 into the return glaze area, and large particles will be intercepted and filtered by the filtration tank 5. When the glaze slurry in the return glaze area reaches the height of the return glaze port, it flows into the glaze bucket 3 from the return glaze port and is recycled and pumped again by the glaze pump 2, keeping the glaze slurry in a flowing state all the time and delaying the precipitation of the glaze slurry.

[0046] In another embodiment of the present invention, it further includes an angular position sensor 27, and the angular position sensor 27 is installed on the rotating shaft of the vacuum suction pipe 30. The angular position sensor 27 feeds back the detected data to the electric control box 9, and the electric control box 9 controls the operation of the glaze circulation system, the lifting structure 8, the flipping structure 7, the cleaning structure 6, the sewage treatment structure, etc. according to the detected data.

[0047] In another embodiment of the present invention, a sewage discharge port 20 is further provided on the side of the glaze tank 4. The glaze tank 4 can be conveniently cleaned through the sewage discharge port 20.

[0048] In the description of the present invention, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
