Description

Technical Field

[0001] This utility model relates to the field of sheet surface treatment technology, and in particular to a polypropylene sheet surface treatment device. Background Technology

[0002] In the industrial production field, polypropylene sheets are widely used in many industries such as packaging, electronics, and automobiles due to their advantages such as light weight, corrosion resistance, and good insulation. However, after molding, polypropylene sheets often have problems such as uneven surface roughness and insufficient gloss, which will affect the effect of subsequent printing, coating, bonding and other processes. Therefore, it is particularly important to treat polypropylene sheets to improve their surface properties. An efficient, multi-functional surface treatment equipment that can adapt to different specifications of sheets has become an urgent need in the industry. Such equipment should not only improve the surface quality of the sheets, but also have good environmental performance and ease of operation to meet the requirements of efficient and green development in modern industrial production.

[0003] A search revealed a sheet metal surface treatment device in publication number CN219380239U. This application discloses a sheet metal surface treatment device, relating to the field of sheet metal processing machinery, including a frame, a conveying mechanism, and a polishing mechanism. The conveying mechanism includes several conveying components, which are spaced apart on the frame for conveying sheet metal. The polishing mechanism includes several polishing components, which are positioned on the frame between adjacent conveying components for surface treatment of the sheet metal conveyed by the conveying components. This solves the problem of multi-sided processing of sheet metal, especially the automated polishing of narrow, long, or large-sized sheet metal, enabling simultaneous polishing of both sides of the sheet metal, saving labor costs, conserving floor space, and improving sheet metal processing efficiency and quality. However, in this application, because the positions of the drive rollers and polishing belt are fixed, the equipment can only process sheet metal within a specific thickness range. When encountering sheet metal of varying thicknesses, operators need to spend a significant amount of time and effort adjusting the equipment, and may even need to replace some parts to continue processing. This not only reduces production efficiency but also increases production costs. Moreover, frequent adjustments and replacements of parts can lead to a decrease in equipment precision, affecting the surface treatment quality of the sheet metal. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a surface treatment device for polypropylene sheets, which aims to improve the problem that existing technologies cannot easily polish polypropylene sheets of different specifications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A surface treatment device for polypropylene sheets includes a processing table, a connecting plate slidably connected to the top of the processing table, a transmission roller fixedly connected to the top of the connecting plate, a polishing belt fixedly connected to the top of the connecting plate, an adjustment component inside the processing table, and a cleaning component at the bottom of the processing table.

[0007] The adjustment assembly includes a fixed column and a fixed plate. The bottom of the fixed plate is fixedly connected to the top of the processing table. The outer wall of the fixed column is fixedly connected to the inside of the fixed plate. The inside of the connecting plate is slidably connected to the outer wall of the fixed column.

A second spring is sleeved on the outer wall of the fixed column. One end of the second spring is fixedly connected to the outer wall of the fixed plate, and the other end of the second spring is fixedly connected to the outer wall of the connecting plate. A limiting plate is fixedly connected to the top of the processing table. The limiting plate is positioned between the two connecting plates on both sides.

[0008] As a further description of the above technical solution:

[0009] The cleaning assembly includes a fan and a collection box. The outer wall of the fan is fixedly connected to the inside of the processing table, and the fan is located on top of the polishing belt.

[0010] As a further description of the above technical solution:

[0011] The processing table has a collection port inside, the top of the collection box is fixedly connected to the bottom of the processing table, and the collection box is located at the bottom of the collection port;

[0012] As a further description of the above technical solution:

[0013] The collection box is slidably connected to a collection cabinet, the collection cabinet has a pull groove, a collection trough, and a drainage trough inside;

[0014] As a further description of the above technical solution:

[0015] The collection cabinet is slidably connected to a card plate inside, and the outer wall of the card plate is slidably connected to the inside of the collection box. A spray head is fixedly connected inside the collection box.

[0016] As a further description of the above technical solution:

[0017] The collection cabinet has a moving groove inside and a limiting groove inside. A limiting block is slidably connected inside the collection cabinet. A filter plate is fixedly connected to the outer wall of the limiting block. A handle is fixedly connected to the top of the filter plate.

[0018] As a further description of the above technical solution:

[0019] The other end of the card plate is fixedly connected to a limiting plate. The outer wall of the limiting plate is slidably connected to the inside of the moving groove.

[0020] As a further description of the above technical solution:

[0021] A spring is fitted on the outer wall of the connecting column. One end of the spring is fixedly connected to the outer wall of the limiting plate, and the other end of the spring is fixedly connected to the inner wall of the moving groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the connecting plate achieves its movement function by placing the plate. When the plate is placed, the plate drives the transmission rollers on both sides and cooperates with the second spring to make the connecting plate slide on the surface of the fixed column, thereby adjusting the distance between the polishing belts on both sides and the transmission rollers.

Then, the collection cabinet is moved by pulling the pull groove. When the pull groove is pulled, the card plate and the limiting plate move and cooperate with the spring to make the card plate slide inside the collection box, so as to conveniently remove the collection cabinet for centralized processing of the debris inside. During the collection process, the collected debris is dusted by the nozzle and the drainage channel to prevent the top fan from blowing continuously and causing it to float around. Furthermore, the debris is collected in layers by the filter plate 27, which solves the problem that the debris generated by polishing and grinding cannot be mechanically collected and cleaned, and improves the environmental friendliness of the device.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0032] Reference Figures 1-3 The present invention provides an embodiment of a polypropylene sheet surface treatment device, including a processing table 1, a connecting plate 6 slidably connected to the top of the processing table 1, a transmission roller 2 fixedly connected to the top of the connecting plate 6, and a polishing belt 4 fixedly connected to the top of the connecting plate 6. The polishing belt 4 is made of high-strength polyester fiber as a base and is uniformly coated with high-performance abrasive, which can efficiently polish the sheet surface to meet different process requirements. An adjustment component is provided inside the processing table 1, and a cleaning component is provided at the bottom of the processing table 1.

[0033] The adjustment assembly includes a fixed column 7 and a fixed plate 12. The bottom of the fixed plate 12 is fixedly connected to the top of the processing table 1. The outer wall of the fixed column 7 is fixedly connected to the inside of the fixed plate 12. The inner wall of the connecting plate 6 is slidably connected to the outer wall of the fixed column 7. Both ends of the fixed column 7 are fixedly connected to fixed rings 13. The fixed rings 13 are made of carbon steel and have been galvanized to enhance their rust resistance. The fixing ring 13 is tightly fixed to both ends of the fixing column 7 and is set on the other side of the fixing plate 12. It plays a role in restricting the movement of the connecting plate 6 and ensuring the safety and stability of the equipment operation. The outer wall of the connecting plate 6 is provided with a locking component. The outer wall of the fixing column 7 is fitted with a spring 11. One end of the spring 11 is fixedly connected to the outer wall of the fixing plate 12, and the other end of the spring 11 is fixedly connected to the outer wall of the connecting plate 6. The top of the processing table 1 is fixedly connected with a limiting plate 14. The limiting plate 14 is set between the two connecting plates 6 on both sides. When the thickness of the polypropylene sheet changes, the connecting plate 6 will slide along the fixing column 7 under the action of the sheet, thereby compressing or stretching the spring 11, realizing the automatic adjustment of the distance between the transmission roller 2 and the polishing belt 4. The locking component includes a fixing block 28 and an eccentric wheel 29. The outer wall of the fixing block 28 is fixedly connected to the outer wall of the connecting plate 6, and the outer wall of the eccentric wheel 29 is rotatably connected to the inside of the fixing block 28. The outer wall of the eccentric wheel 29 is fixedly connected with a rotating rod 30.

[0034] Specifically, when performing surface polishing on polypropylene sheets, the polypropylene sheet to be treated is first placed stably between the two drive rollers 2. The drive rollers 2 are made of high-strength alloy steel, and their surfaces are finely polished, possessing good wear resistance and transmission stability. After the sheet is properly placed, the drive rollers 2 begin to rotate, using the friction between them and the sheet to propel it forward, allowing it to accurately pass through the polishing belt 4 for polishing. Furthermore, the thickness of the sheet exerts a pushing force on the two drive rollers 2 during placement. This pushing force causes the drive rollers 2 to smoothly slide the connecting plate 6 connected to it against the outer wall of the fixed column 7. The fixed column 7 is made of stainless steel, ensuring stable support and smooth sliding. As the connecting plate 6 slides, the connecting plate... The second spring 11 is compressed. After the board is placed, the second spring 11 rebounds and automatically adjusts the distance between the two transmission rollers 2 and the polishing belt 4 to accurately match the thickness of the board. Therefore, it is possible to process polypropylene boards of different thicknesses without changing the equipment, which improves work efficiency and equipment versatility. After the two transmission rollers 2 and the polishing belt 4 are adjusted according to the thickness of the polypropylene board, the rotating rod 30 can be rotated. The rotating rod 30 will drive the eccentric wheel 29 to rotate flexibly inside the fixed column 7. As the eccentric wheel 29 rotates, it gradually squeezes the fixed column 7, thereby firmly locking the position of the connecting plate 6. This effectively prevents the board from falling off due to the sliding of the connecting plate 6 during processing, ensuring the safety and stability of the processing process.

[0035] Working principle: When polishing the surface of polypropylene sheets, the sheet is placed between the two transmission rollers 2. The transmission rollers 2 drive the sheet through the polishing belt 4 for polishing. At the same time, the thickness of the sheet pushes the two transmission rollers 2 to move, thereby causing the connecting plate 6 to slide on the outer wall of the fixed column 7, compressing the connecting spring 11. Then, the spring 11 rebounds, automatically adapting the distance between the two transmission rollers 2 and the polishing belt 4 to the sheet thickness. After the adaptation is complete, the rotating rod 30 can be rotated, which drives the eccentric wheel 29 to rotate inside the fixed column 7, locking the position of the connecting plate 6 to prevent slippage and sheet detachment. This allows for convenient processing of sheets of different thicknesses, avoiding the need to use different machines for different thicknesses. Example 2

[0036] Reference Figure 1 - Figure 4The cleaning components include a blower 3 and a collection box 5. The blower 3 is fixedly connected to the inside of the processing table 1. The blower 3 is located on top of the polishing belt 4. When the equipment starts to perform surface treatment on the polypropylene sheet, the blower 3 will operate synchronously. Its strong airflow can effectively blow the debris generated by the polishing belt 4 downwards during the polishing process. A collection port 10 is provided inside the processing table 1. The top of the collection box 5 is fixedly connected to the bottom of the processing table 1. The inner wall of the collection port 10 is smoothed and made of stainless steel, which can reduce the resistance of the debris during the falling process, so that the blown debris can fall smoothly into the collection box 5 below through the collection port 10. The collection box 5 is located at the bottom of the collection port 10 to ensure that it can completely catch the debris falling from the collection port 10. A collection cabinet 8 is slidably connected inside the collection box 5. The collection cabinet 8 has a pull groove 9 inside. The surface of the pull groove 9 is treated with anti-slip to ensure that it is safer and more convenient to pull the collection cabinet 8. A collection groove 22 is provided inside the collection cabinet 8, and a drainage channel is provided inside the collection cabinet 8. The collection cabinet 8 has a slidingly connected card plate 15 inside the trough 24. The outer wall of the card plate 15 is slidably connected to the inside of the collection box 5. The collection box 5 has a fixedly connected nozzle 23, which performs dust suppression on the collected debris to prevent the light debris from easily drifting under the continuous wind force of the fan 3. The collection cabinet 8 has a moving trough 17 and a limiting trough 20 inside. The collection cabinet 8 has a slidingly connected limit block 26 inside. The outer wall of the limit block 26 is fixedly connected to a filter plate 27. 7. A handle 25 is fixedly connected to the top. A limit plate 16 is fixedly connected to the other end of the card plate 15. The outer wall of the limit plate 16 is slidably connected to the inside of the moving groove 17. A connecting post 19 is fixedly connected to the outer wall of the moving groove 17. A limiting ring 21 is fixedly connected to the outer wall of the connecting post 19. The outer wall of the limiting ring 21 is slidably connected to the inside of the limiting groove 20. A spring 18 is sleeved on the outer wall of the connecting post 19. One end of the spring 18 is fixedly connected to the outer wall of the limit plate 16, and the other end of the spring 18 is fixedly connected to the inner wall of the moving groove 17.

[0037] Specifically, during the surface treatment of polypropylene sheets, to ensure a clean and environmentally friendly working environment, when the equipment is started and the treatment work officially begins, the blower 3 will also be turned on simultaneously. The blower 3 adopts an axial flow structure, and its powerful airflow can quickly lift the debris generated during the treatment process. Under the action of the blower 3, these debris are blown into the collection box 5 through the collection port 10 opened inside the processing table 1 along the preset airflow path. The collection box 5 is made of sturdy cold-rolled steel plate and has good load-bearing capacity and sealing performance. After the debris falls into the collection box 5, it will fall directly into the collection groove 22 opened inside the collection cabinet 8. When too much debris accumulates in the collection groove 22, the operator can directly pull the pull groove 9 on the collection cabinet 8. The surface of the pull groove 9 is treated with anti-slip treatment for easy gripping and operation. When the pull groove 9 is pulled, the collection cabinet 8 moves accordingly. Since the surface of the clamping plate 15 is inclined, the movement of the collection cabinet 8 pushes the clamping plate 15 to slide inwards. The clamping plate 15 is fixedly connected to the limiting plate 16, which slides smoothly inside the moving groove 17, thereby driving the connecting column 19 to move. During the movement of the connecting column 19, the spring 18 sleeved on its outer wall is compressed, simultaneously driving the limiting ring 21 to move inside the limiting groove 20. When a certain position is reached, the collection cabinet 8 can be easily removed for centralized treatment of internal debris, effectively preventing debris from polluting the environment. It is particularly worth mentioning that the nozzle 23 plays a crucial role when debris passes through the collection port 10. The nozzles 23 are evenly distributed around the collection port 10. Once activated, the system sprays a fine stream of water in a fan shape, powerfully impacting and securing debris inside the collection cabinet 8, achieving efficient dust suppression. The sprayed water, carrying debris, flows through the drainage trough 24 to the filtration device. The filtration device uses multiple layers of filters and purification processes to purify the water, allowing it to flow back to the nozzle 23 for recycling and continuous support for dust suppression operations. Furthermore, when the collection cabinet 8 is removed for processing, the operator can move the filter plate 27 using the handle 25. The filter plate 27 has meshes with different pore sizes, which can isolate and filter debris of different sizes, facilitating subsequent targeted processing based on the different sizes of the debris, further improving the efficiency and environmental friendliness of the entire debris processing process.

[0038] Working principle: During processing, the blower 3 is started simultaneously. The blower 3 blows the generated debris through the collection port 10 into the collection box 5, causing it to fall into the collection groove 22 inside the collection cabinet 8. When too much debris is collected, the pull groove 9 can be pulled directly, which moves the collection cabinet 8. Because the surface of the clamping plate 15 is inclined, it is pushed to slide inward. Then, the clamping plate 15 drives the limiting plate 16 to slide in the moving groove 17, thereby moving the connecting column 19, compressing the spring 18, and moving the limiting ring 21 in the limiting groove 22. The internal movement of the collection cabinet 8 allows for centralized processing of internal debris, preventing environmental pollution. Simultaneously, as debris passes through the collection port 10, water from the nozzle 23 holds the debris inside the collection cabinet 8, reducing dust and preventing it from drifting freely with the wind and causing pollution. The sprayed water is filtered and discharged through the drainage trough 24 and can be recycled for continuous dust reduction. During processing, the filter plate 27 can be moved using the handle 25; the internal filter plate 27 separates and filters debris of different sizes, facilitating subsequent separate processing.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
