Description

Technical Field

[0001] This utility model relates to the field of plastic sheet production technology, and in particular to a grinding machine for producing PVC transparent plastic sheets that is easy to clean. Background Technology

[0002] PVC transparent plastic sheet is a transparent decorative board made of PVC as the base material, with added plasticizers and anti-aging agents, and is formed by extrusion. Sanding can effectively eliminate these imperfections, making the surface smoother and flatter, and improving the overall appearance quality.

[0003] Currently, existing grinding machines (such as patent publication number: CN221337931U) disclose an edge trimming device for plastic sheet production. When the edge trimming mechanism grinds and trims the edge of the plastic sheet body, no manual operation is required. This not only saves time and effort but also reduces labor intensity. Furthermore, the edge trimming mechanism can complete the trimming of the four sides of the plastic sheet body by manually changing the position of the plastic sheet body to make the edge part fit tightly with the grinding wheel.

[0004] In the aforementioned patent, grinding the plastic sheet easily generates dust, which permeates the working environment. The suspended dust also adheres to the surface of the ground PVC sheet, forming granular defects or scratches, affecting the transparency and smoothness of the sheet, and leading to a decrease in the product qualification rate. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a grinding machine for the production of transparent PVC plastic sheets that is easy to clean. This solves the technical problem that grinding plastic sheets easily generates dust, which permeates the working environment. Suspended dust also adheres to the surface of the ground PVC sheets, forming granular defects or scratches, affecting the transparency and smoothness of the sheets, and leading to a decrease in product qualification rate.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A grinding machine for producing PVC transparent plastic sheets that is easy to clean includes a processing table, a sheet body, and an adjustment frame. A grinding module is provided at the bottom end of the adjustment frame. The grinding module moves along the guide rail groove at the bottom end of the adjustment frame. The machine also includes...

[0008] A cleaning assembly is disposed on the side of the adjustment frame. The cleaning assembly includes a support plate, a support plate, a rotating arm, and an elastic support block. A scraper is fixedly installed at the bottom end of the elastic support block, and at least two atomizing nozzles are fixedly installed at the side end of the elastic support block.

[0009] Preferably, the scraper is made of sponge material, and the elastic support block is made of memory metal material;

[0010] The support plate has columns fixedly installed at both ends that are rotatably connected to the rotating arm, and the top end of the rotating arm has at least two insertion holes.

[0011] Preferably, a fastening screw is rotatably mounted on the top of the column, and a retaining ring is provided on the surface of the fastening screw. The thread helix angle of the fastening screw and the column is less than the friction angle.

[0012] The support plate is equipped with a water inlet pipe inside, and the top end of the water inlet pipe penetrates the interior of the support plate.

[0013] The top of the processing table is equipped with multiple drive rollers, and the bottom of the adjustment frame is equipped with a hydraulic rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects;

[0015] In this invention, the atomizing nozzle sprays water onto the surface of the board body. As the board body slides along the bottom of the scraper, the scraper works in conjunction with the nozzle to clean the dust generated during the grinding process, keeping the board surface clean. The water spray from the atomizing nozzle effectively moistens the dust and prevents it from being stirred up. Meanwhile, the scraper is made of sponge material, which can better absorb and wipe away dust, improving the cleaning effect and preventing secondary pollution of the board surface by the dust, thus ensuring the cleanliness of the product.

[0016] In this invention, two rotating arms can rotate synchronously at the side ends of the support plate. The rotating arms exert tension on both ends of the elastic support block, causing the elastic support block to bend at the side ends of the support plate. The elastic support block and the scraper bend synchronously. The elastic support block is made of flexible metal material. With the synchronous bending of the scraper, it can fit well with plates of different sizes and shapes, enhancing the versatility and adaptability of the equipment. Attached Figure Description

[0023] This application provides a sanding machine for producing transparent PVC plastic sheets that is easy to clean. It effectively solves the problem that sanding plastic sheets easily generates dust, which permeates the working environment and adheres to the surface of the sanded PVC sheet, forming granular defects or scratches that affect the transparency and smoothness of the sheet, leading to a decrease in product qualification rate. The atomizing nozzle sprays water onto the surface of the sheet body. As the sheet body slides along the bottom of the scraper, the scraper works in conjunction with the water to clean the floating dust generated during sanding, keeping the sheet surface clean. The atomizing nozzle effectively moistens the floating dust and prevents it from being stirred up. Simultaneously, the scraper is made of sponge material, which better absorbs and wipes away dust, improving the cleaning effect and preventing secondary pollution of the sheet surface by floating dust, thus ensuring the cleanliness of the product. Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that grinding plastic sheets easily generates dust, which permeates the working environment. Suspended dust also adheres to the surface of the ground PVC sheet, forming particulate defects or scratches, affecting the transparency and smoothness of the sheet, and leading to a decrease in product qualification rate. The overall idea is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a grinding machine for the production of PVC transparent plastic sheets that is easy to clean. It includes a processing table 11, a sheet body 12, and an adjustment frame 13. A grinding module 14 is provided at the bottom of the adjustment frame 13. The grinding module 14 moves along the guide rail groove at the bottom of the adjustment frame 13. The grinding module 14 includes a motor and a grinding disc. The motor rotates to drive the grinding disc to grind the surface of the sheet body 12.

[0026] The cleaning component is located on the side of the adjusting frame 13. The cleaning component includes a support plate 15, a support plate 16, a rotating arm 17, and an elastic support block 18. A scraper 21 is fixedly installed at the bottom of the elastic support block 18, and at least two atomizing nozzles 19 are fixedly installed on the side of the elastic support block 18. The plate body 12 moves at the top of the processing table 11. The adjusting frame 13 drives the grinding module 14 and the support plate 15 to move downward synchronously, so that the bottom of the grinding module 14 and the scraper 21 simultaneously contact the surface of the plate body 12. While the grinding module 14 is grinding, the plate body 12 can slide at the bottom of the scraper 21. The atomizing nozzles 19 spray water onto the surface of the plate body 12, which works with the scraper 21 to clean the floating dust on the surface of the plate body 12.

[0027] The scraper 21 is made of sponge material, and the elastic support block 18 is made of memory metal material. The elastic support block 18 can be bent, and the elastic support block 18 and the scraper 21 can be bent synchronously to adapt to different sizes of the board body 12.

[0028] The support plate 16 has columns 22 fixedly installed at both ends and rotatably connected to the rotating support arm 17. The top of the rotating support arm 17 has at least two insertion holes. The rotating support arm 17 is connected to the support plate 16 through the columns 22. The two rotating support arms 17 can rotate synchronously at the side end of the support plate 16. The rotating support arm 17 generates tension on both ends of the elastic support block 18, causing the elastic support block 18 to bend at the side end of the support plate 16.

[0029] A fastening screw 24 is rotatably mounted on the top of the column 22. A retaining ring 25 is provided on the surface of the fastening screw 24. The thread helix angle of the fastening screw 24 and the column 22 is less than the friction angle. By rotating the fastening screw 24 in the opposite direction, the end of the fastening screw 24 rotates inside the column 22, causing the retaining ring 25 to move downward. As the fastening screw 24 is continuously rotated, the retaining ring 25 follows the fastening screw 24 and moves downward. The retaining ring 25 presses against the top of the rotating support arm 17, fixing the angle of the rotating support arm 17. At the same time, the rotation of the fastening screw 24 is stopped, and the fastening screw 24 and the column 22 can lock themselves.

[0030] The support plate 16 is equipped with a water inlet pipe 23. The top end of the water inlet pipe 23 penetrates the interior of the support plate 15. The pump is connected through the water inlet pipe 23 to deliver water to the interior of the support plate 16. The support plate 16, in conjunction with the branch pipe, delivers the water to the interior of the atomizing nozzle 19.

[0031] Multiple drive rollers are provided at the top of the processing table 11. The drive rollers drive the plate body 12 to move at the top of the processing table 11. A hydraulic rod is installed at the bottom of the adjustment frame 13 to control the adjustment frame 13 to rise and fall at the top of the processing table 11, thereby adjusting the height of the grinding module 14.

[0032] Working principle:

[0033] The first step is to place the sheet body 12 on the processing table 11. Multiple drive rollers at the top of the processing table 11 start to operate, driving the sheet body 12 to move smoothly at the top of the processing table 11 and enter the grinding area. The hydraulic rod installed at the bottom of the adjusting frame 13 controls the adjusting frame 13 to rise and fall at the top of the processing table 11, moving the grinding module 14 and the support plate 15 downwards synchronously until the bottom of the grinding module 14 and the scraper 21 simultaneously contact the surface of the sheet body 12. The motor in the grinding module 14 starts, and the rotation of the motor drives the grinding disc to rotate at high speed, grinding the surface of the sheet body 12 to remove surface defects and achieve the required flatness and smoothness.

[0034] If it is necessary to adapt to different sizes of plate bodies 12, the angle of the elastic support block 18 can be adjusted. The fastening screw 24 is rotated in the opposite direction. The end of the fastening screw 24 rotates inside the column 22, causing the insert ring 25 to move downward. Continue to rotate the fastening screw 24, and the insert ring 25 moves downward with the fastening screw 24, loosening the fixation of the angle of the rotating support arm 17. At this time, the two rotating support arms 17 can deflect synchronously at the side end of the support plate 16. The rotating support arm 17 generates tension on both ends of the elastic support block 18, causing the elastic support block 18 to bend at the side end of the support plate 16. The elastic support block 18 and the scraper 21 bend synchronously. After adjusting to the appropriate angle, stop rotating the fastening screw 24. Since the thread helix angle of the fastening screw 24 and the column 22 is less than the friction angle, the two lock themselves, fixing the angle of the rotating support arm 17, so that the elastic support block 18 and the scraper 21 are kept in the adjusted position.

[0035] The second step involves connecting a pump to the water inlet pipe 23 to deliver water to the inside of the support plate 16. The support plate 16, in conjunction with a branch pipe, then delivers the water to the inside of the atomizing nozzle 19. The atomizing nozzle 19 sprays water onto the surface of the board body 12. As the board body 12 slides at the bottom of the scraper 21, the scraper 21 cleans the dust generated during the grinding of the board body 12 surface, keeping the board surface clean. Driven by the drive roller, the board body 12 moves continuously, the grinding module 14 grinds continuously, and the cleaning component cleans simultaneously until the entire board processing is completed.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
