Description

Technical Field

[0001] This invention belongs to the field of polishing, specifically relating to a polishing device for the wall of an ultra-high molecular weight polyethylene plastic barrel. Background Technology

[0002] During the grinding process of ultra-high molecular weight polyethylene (UHMWPE) plastic barrels, the material has extremely poor thermal conductivity and a low softening point. Conventional grinding methods can easily lead to localized overheating, surface melting and adhesion of the abrasive belt, and the grinding debris carries strong static electricity, which can easily cause cold welding and block the dust extraction pipe. Existing grinding equipment lacks design for the low thermal conductivity of UHMWPE, and cannot effectively control the barrel wall temperature rise and grinding debris adhesion, resulting in barrel thermal deformation, poor surface quality, and restricting processing efficiency and yield.

[0003] Patent CN215432844U discloses a grinding device for the wall of ultra-high molecular weight polyethylene (UHMWPE) plastic buckets, including a base, a support frame, a placement groove, and an operation panel. The placement groove is located in the middle of the upper end of the base, and the support frame is located on both sides of the placement groove. A bracket is mounted on one side wall of the support frame, and the operation panel is located on the upper end of the bracket. A motor is located in the middle of the upper end of the support frame, and a turntable is located in the middle of the bottom end of the support frame. A hydraulic rod is located at the bottom end of the turntable, and a connecting plate is located at the bottom end of the hydraulic rod. A cylinder is mounted on the outer wall of the connecting plate. This patent, by using a connecting plate and a cylinder, allows the cylinder to automatically push the grinding discs to contact the inner wall of the plastic bucket when the connecting plate is inside the bucket. Furthermore, since there are four grinding discs, the grinding efficiency of the device can be effectively improved, saving time and enhancing its practicality.

[0004] The above-mentioned device also has the following problems: during the grinding of the inner wall of the plastic bucket, it is difficult to cool the bucket wall before or after grinding in a timely manner. During the long grinding process, the inner wall of the plastic bucket is prone to heat generation due to friction, resulting in excessive temperature and deformation, which affects the subsequent grinding quality and efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a grinding device for the wall of ultra-high molecular weight polyethylene plastic buckets, so as to solve the problem that plastic buckets are prone to deformation during long-term grinding.

[0006] To achieve the above objectives, the present invention provides a grinding device for the wall of ultra-high molecular weight polyethylene plastic barrels, comprising: a support frame on which a sample barrel is placed; an electric telescopic rod mounted on the support frame; a cooling mechanism disposed on the inner wall of the support frame; a support mechanism disposed within the support frame; an electric rotating disk fixedly connected to the telescopic end of the electric telescopic rod; a fixed frame fixedly connected to the output end of the electric rotating disk; a double-headed telescopic rod fixedly connected to the inner wall of the fixed frame; a connecting frame fixedly connected to the telescopic end of the double-headed telescopic rod; and a grinding roller rotatably connected to the inner wall of the connecting frame. A diversion column is fixedly connected to the wall, and a high-pressure air nozzle is fixedly connected to the circumferential surface of the diversion column. A fan is fixedly connected inside the fixed frame, and an elastic telescopic rod is fixedly connected to the front of the fixed frame. A fixed plate is fixedly connected to the telescopic end of the elastic telescopic rod, and a clamping post is fixedly connected to the inner wall of the fixed plate. A top grinding disc is slidably connected to the inner wall of the fixed frame, and a three-point clamping module is provided on the bracket, which can continuously grind the inner wall of the sample bucket. Through the above operations, the grinding roller can grind plastic buckets with different inner wall diameters, thus improving the grinding speed of the device.

[0007] In the above technical solution, the sample bucket is further positioned on the movement trajectory of the grinding roller, the high-pressure air nozzle is connected to the diverting column, the diverting column is connected to the fan through an air pipe, the locking pin is in contact with the top grinding disc, and the locking pin is used to limit and lock the movement of the top grinding disc. In order to avoid the plastic bucket from thermal deformation due to excessive heat, the high-pressure air nozzle can effectively cool the grinding area of ​​the plastic bucket. It can move along the movement trajectory of the grinding roller and cool the grinding area in time, thereby improving the grinding efficiency and quality of the device.

[0008] In the above technical solution, the sample bucket is further located on the movement trajectory of the top grinding disc, and the top grinding disc is used to grind the inner wall of the sample bucket. The fixed plate is provided with a handle, and the handle is used by the operator to pull the fixed plate. The movement of the fixed frame will synchronously drive the fan to move. At the same time, during the movement of the connecting frame, the connecting frame will synchronously drive the diversion column to move, and the movement of the diversion column will synchronously drive the high-pressure air nozzle to move.

[0009] In the above technical solution, the cooling mechanism further includes a cylinder, which is fixedly connected to the inner wall of the support.

A cold liquid tank is fixedly connected to the right side of the fixed rod. An elastic telescopic rod II is fixedly connected to the inner wall of the fixed rod. A cooling arc plate is fixedly connected to the telescopic end of the elastic telescopic rod II. A sliding limiting post is slidably connected to the inner wall of the fixed rod. During the circulation of cooling water in the circulating water tank of the cooling arc plate, the cooling arc plate can cool the surface of the sample bucket, so that the outer surface temperature of the sample bucket gradually decreases. This allows the outer surface of the sample bucket to be cooled before the inner wall of the sample bucket is polished. It can continuously absorb heat from the inner wall of the plastic bucket from the outer surface of the sample bucket, avoiding thermal deformation of the plastic bucket due to excessive inner wall temperature, and improving polishing efficiency and quality.

During the movement of the movable scraper ring, it can scrape off the grinding debris adhering to the surface of the grinding roller, thereby improving the service life of the grinding roller and improving the grinding quality and efficiency of the grinding roller, and avoiding the impact of grinding quality on the grinding quality due to the debris adhering to the grinding roller.

[0011] In the above technical solution, a spring is further provided between the sliding limiting post and the fixed rod. The sliding limiting post is in contact with the cooling arc plate. The cold liquid tank and the cooling arc plate are connected to each other through a water pipe. A water pump is provided on the inner wall of the cold liquid tank. The sample bucket is located on the movement trajectory of the sliding limiting post. The movable scraper ring is slidably connected to the circumferential surface of the limiting post. Gear 1 and Gear 2 mesh, and Gear 1 is used to drive Gear 2 to rotate. A circulating water tank is provided on the inner wall of the cooling arc plate. The grinding roller will rotate around itself as the rotation center. During the rotation of the grinding roller, the grinding roller will synchronously drive Gear 1 to rotate. During the rotation of Gear 1, Gear 1 will synchronously drive Gear 2 to rotate.

[0012] In the above technical solution, the support mechanism further includes a fixed groove rod, the inner wall of which is slidably connected to an inclined rod, and the inner wall of the inclined rod is rotatably connected to a hinged arc plate via a torsion spring. This allows the hinged arc plate to apply an expansion force to the inner wall of the sample container, which is relatively equal to the surface clamping force. This prevents the sample container from undergoing large deformation during the polishing process, thereby affecting the polishing quality and efficiency of the device.

[0013] In the above technical solution, the support mechanism further includes a rotating column, which is rotatably connected to the inner wall of the hinged arc plate. A glue column is fixedly connected to the circumferential surface of the hinged arc plate, which can stabilize the expansion force of the hinged arc plate on the sample barrel, improve the polishing quality of the device, and reduce damage during the polishing process.

The movement of the hinged arc plate can synchronously drive the rotating column to move. During the movement of the rotating column, the rotating column will drive the glue column to move synchronously.

Through the above operations, the polishing roller can polish plastic barrels with different inner wall diameters, thus increasing the polishing speed of the device, effectively cooling the polishing area of ​​the plastic barrel, and following the movement trajectory of the polishing roller to cool the polishing area in a timely manner, thereby improving the polishing efficiency and quality of the device.

This allows for cooling of the outer surface of the sample barrel before polishing the inner wall, continuously absorbing heat from the outer surface to prevent thermal deformation due to excessively high inner wall temperature. This improves polishing efficiency and quality. During its movement, the moving scraper ring removes polishing debris adhering to the surface of the polishing roller, extending the roller's lifespan and improving polishing quality and efficiency, preventing debris from affecting the polishing quality.

[0017] 3. This ultra-high molecular weight polyethylene plastic barrel wall polishing device, through the coordinated movement of the fixed groove rod, inclined rod, hinged arc plate, rotating column, and glue column, enables the hinged arc plate to apply an expansion force to the inner wall of the sample barrel.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-7As shown, one embodiment of the present invention provides: a grinding device for the wall of an ultra-high molecular weight polyethylene plastic barrel, comprising: a support 1, a sample barrel 2 placed on the support 1, an electric telescopic rod 3 mounted on the support 1, a cooling mechanism 4 mounted on the inner wall of the support 1, a support mechanism 5 mounted inside the support 1, an electric rotating disk 6 fixedly connected to the telescopic end of the electric telescopic rod 3, a fixing frame 7 fixedly connected to the output end of the electric rotating disk 6, a double-headed telescopic rod 8 fixedly connected to the inner wall of the fixing frame 7, and a connecting frame 9 fixedly connected to the telescopic end of the double-headed telescopic rod 8. The inner wall of the frame 7 is rotatably connected to a grinding roller 10. The inner wall of the connecting frame 9 is fixedly connected to a diverter column 11. The circumferential surface of the diverter column 11 is fixedly connected to a high-pressure air nozzle 12. The inside of the fixed frame 7 is fixedly connected to a fan 13. The front of the fixed frame 7 is fixedly connected to an elastic telescopic rod 14. The telescopic end of the elastic telescopic rod 14 is fixedly connected to a fixed plate 15. The inner wall of the fixed plate 15 is fixedly connected to a locking post 16. The inner wall of the fixed frame 7 is slidably connected to a top grinding disc 17. A three-point clamping module is provided on the bracket 1. The double-headed telescopic rod 8 is composed of two telescopic rods.

[0022] When the device polishes the inner wall of a UHMWPE plastic bucket, the operator first needs to place the sample bucket 2 in the designated area of ​​the support 1. The three-point clamping module will clamp the UHMWPE plastic bucket. Then, the electric telescopic rod 3 will be activated. The telescopic end of the electric telescopic rod 3 will drive the electric rotating disk 6 to rise. The rising movement of the electric rotating disk 6 will drive the fixed frame 7 to move. During the movement of the fixed frame 7, the fixed frame 7 will simultaneously drive the double-headed telescopic rod 8 to rise. During the rise of the double-headed telescopic rod 8, the double-headed telescopic rod 8 will drive the connecting frame 9 to rise. The connecting frame 9 will simultaneously drive the polishing roller 10 to rise. When the polishing roller 10 is located in the area of ​​the sample bucket 2 that needs to be polished, this... When the double-headed telescopic rod 8 is activated, the telescopic end of the double-headed telescopic rod 8 will drive the connecting frame 9 to move closer to the sample barrel 2. The lateral movement of the connecting frame 9 will drive the grinding roller 10 to move synchronously until the grinding roller 10 contacts the inner wall of the sample barrel 2. Then the electric rotating disk 6 will be activated. The output end of the electric rotating disk 6 will drive the grinding roller 10 to rotate in sequence through the fixed frame 7, the double-headed telescopic rod 8, and the connecting frame 9. At this time, the grinding roller 10 will rotate after contacting the inner wall of the sample barrel 2. During the rotation of the grinding roller 10, the inner wall of the sample barrel 2 can be continuously ground. Through the above operations, the grinding roller 10 can perform grinding operations on plastic barrels with different inner wall diameters, thus improving the grinding speed of the device. The sample barrel 2 is located on the movement trajectory of the grinding roller 10. The high-pressure air nozzle 12 is connected to the diversion column 11. The diversion column 11 is connected to the fan 13 through an air pipe. The locking column 16 is in contact with the top grinding plate 17, and the locking column 16 is used to limit and lock the movement of the top grinding plate 17. The sample barrel 2 is located on the movement trajectory of the top grinding plate 17, and the top grinding plate 17 is used to grind the inner wall of the sample barrel 2. The fixed plate 15 is equipped with a handle, and the handle is used by the operator to pull the fixed plate 15. During use, the movement of the fixed frame 7 synchronously drives the fan 13. Simultaneously, the movement of the connecting frame 9 synchronously drives the diversion column 11, which in turn drives the high-pressure air nozzles 12. As the high-pressure air nozzles 12 move along with the grinding roller 10, the fan 13 starts, discharging air into the diversion column 11 through an air pipe. The diversion column 11 then distributes the air, allowing multiple high-pressure air nozzles 12 to spray air onto the inner wall grinding area of ​​the sample container 2. During the grinding process of the grinding roller 10, the sample container 2 generates heat due to contact grinding. To prevent excessive heat from damaging the plastic... When the material bucket undergoes thermal deformation, the high-pressure air nozzle 12 can effectively cool the grinding area of ​​the plastic bucket. It can move along the movement trajectory of the grinding roller 10, and can cool the grinding area in time, improving the grinding efficiency and quality of the device. At the same time, the fixed frame 7 will also drive the top grinding plate 17 to rotate synchronously during the movement. After moving a certain distance, the top grinding plate 17 can grind the inner bottom of the plastic bucket. When the top grinding plate 17 needs to be replaced, the operator manually pulls the fixed plate 15. The fixed plate 15 will drive the locking post 16, which will release the limit of the top grinding plate 17, enabling the quick replacement of the top grinding plate 17 and improving the grinding efficiency and quality of the device. Overall working principle: It can continuously polish the inner wall of the sample barrel 2. Through the above operations, the polishing roller 10 can polish plastic barrels with different inner wall diameters, thus improving the polishing speed of the device. It can move along the movement trajectory of the polishing roller 10 and cool the polishing area in time, thereby improving the polishing efficiency and quality of the device. The locking column 16 will release the limit of the top polishing plate 17, which can realize the quick replacement of the top polishing plate 17, thereby improving the polishing efficiency and quality of the device.

[0023] like Figures 1-7As shown, the second embodiment of the present invention provides: a cooling mechanism 4 includes a cylinder 401, the cylinder 401 is fixedly connected to the inner wall of the bracket 1, the telescopic end of the cylinder 401 is fixedly connected to a limiting pressure plate 402, the circumferential surface of the limiting pressure plate 402 is fixedly connected to a fixing rod 403, the right side of the fixing rod 403 is fixedly connected to a cold liquid tank 404, the inner wall of the fixing rod 403 is fixedly connected to an elastic telescopic rod 405, the telescopic end of the elastic telescopic rod 405 is fixedly connected to a cooling arc plate 406, and the inner wall of the fixing rod 403 is slidably connected to a sliding limiting post 407; When the device is in use, cylinder 401 is activated. The telescopic end of cylinder 401 drives the limiting pressure plate 402 to move downward. The movement of the limiting pressure plate 402 synchronously drives the fixed rod 403 to move, which in turn drives the coolant tank 404 to move synchronously. Simultaneously, the fixed rod 403 also drives the elastic telescopic rod 405 to move, which in turn drives the cooling arc plate 406 to move. The fixed rod 403 also drives the sliding limiting post 407 to move downward synchronously. As the limiting pressure plate 402 gradually approaches the sample container 2, the sliding limiting post 407 will first prevent the limiting pressure plate 402 from contacting the sample container 2. The sliding limiting post 407 will continue to move downward. At this time, the sample container 2 will push the sliding limiting post 407 upward. After rising a certain distance, the sliding limiting post 407 will release the limiting position of the cooling arc plate 406. The cooling arc plate 406 can be reset by the telescopic reset characteristic of the elastic telescopic rod 405. The telescopic end of the elastic telescopic rod 405 will drive the cooling arc plate 406 to move. After moving a certain distance, the cooling arc plate 406 will contact the sample barrel 2. After the cooling arc plate 406 contacts the outer surface of the sample barrel 2, the water pump in the cold liquid tank 404 can start to circulate the cooling water in itself into the circulating water tank of the cooling arc plate 406 through the water pipe. During the circulation of the cooling water in the circulating water tank of the cooling arc plate 406, the cooling arc plate 406 can cool the surface of the sample barrel 2, so that the outer surface temperature of the sample barrel 2 gradually decreases. It can cool the outer surface of the sample barrel 2 before grinding the inner wall of the sample barrel 2. It can continuously absorb the heat of the inner wall of the plastic barrel from the outer surface of the sample barrel 2, avoid the thermal deformation of the plastic barrel due to the excessive inner wall temperature, and improve the grinding efficiency and quality. Gear 1 408 is fixedly connected to the circumferential surface of the grinding roller 10. A reciprocating screw 409 is rotatably connected to the inner wall of the connecting frame 9. Gear 2 410 is fixedly connected to the circumferential surface of the reciprocating screw 409. A movable scraper ring 411 is movably connected to the circumferential surface of the reciprocating screw 409. A limit post is fixedly connected to the inner wall of the connecting frame 9. A spring is provided between the sliding limit post 407 and the fixed rod 403. The sliding limit post 407 is in contact with the cooling arc plate 406. The cold liquid tank 404 and the cooling arc plate 406 are connected to each other through a water pipe. A water pump is provided on the inner wall of the cold liquid tank 404. The sample bucket 2 is located on the movement trajectory of the sliding limit post 407. The movable scraper ring 411 is slidably connected to the circumferential surface of the limit post. Gear 1 408 meshes with gear 2 410, and gear 1 408 is used to drive gear 2 410 to rotate. A circulating water tank is opened on the inner wall of the cooling arc plate 406. As the polishing roller 10 contacts and rotates against the inner wall of the sample container 2, friction arises between it and the container. The polishing roller 10 rotates around itself, and this rotation simultaneously drives gear 408 to rotate. Gear 408, in turn, drives gear 410 to rotate. This rotation of gear 410 then moves the reciprocating screw 409, which in turn moves the moving scraper. The ring 411 rotates, but at this time the movable scraper ring 411 slides on the circumferential surface of the limiting post. At this time, the limiting post causes the movable scraper ring 411 to move up and down reciprocally through the reciprocating groove opened on the surface of the reciprocating screw 409 during the rotation of the reciprocating screw 409. During the movement, the movable scraper ring 411 can scrape off the grinding debris adhering to the surface of the grinding roller 10, improve the service life of the grinding roller 10, and improve the grinding quality and efficiency of the grinding roller 10, and avoid the grinding quality being affected by the debris adhering to the grinding roller 10. The support mechanism 5 includes a fixed groove rod 501, an inclined rod 502 is slidably connected to the inner wall of the fixed groove rod 501, and a hinged arc plate 503 is rotatably connected to the inner wall of the inclined rod 502 through a torsion spring. When the device is in use, as the connecting frame 9 moves laterally driven by the double-headed telescopic rod 8, the connecting frame 9 will simultaneously drive the fixed groove rod 501 to move laterally. The lateral movement of the fixed groove rod 501 will drive the inclined rod 502 to move. During the movement of the inclined rod 502, the inclined rod 502 will drive the hinged arc plate 503 to move. After moving a certain distance, the hinged arc plate 503 will contact the inner wall of the sample barrel 2 before the grinding roller 10. After the hinged arc plate 503 contacts the sample barrel 2, the grinding roller 10 will continue to move until it contacts the inner wall of the sample barrel 2. The inner wall of the sample container 2 is tightly pressed against the surface. As the grinding roller 10 continues to move, the inclined rod 502 slides on the inner wall of the fixed groove rod 501. At the same time, the hinged arc plate 503 changes its angle synchronously and remains in contact with the inner wall of the sample container 2. During this process, the rotation of the hinged arc plate 503 and the position of the inclined rod 502 on the inner wall of the fixed groove rod 501 enable the hinged arc plate 503 to apply an expansion force to the inner wall of the sample container 2. This force is relatively equal to the surface clamping force, which can prevent the sample container 2 from undergoing large deformation during grinding, thereby affecting the grinding quality and efficiency of the device. The support mechanism 5 also includes a rotating column 504, which is rotatably connected to the inner wall of the hinged arc plate 503. A glue column 505 is fixedly connected to the circumferential surface of the hinged arc plate 503. The sample bucket 2 is located on the movement trajectory of the hinged arc plate 503 and the movement trajectory of the glue column 505. A spring is provided between the inclined rod 502 and the fixed groove rod 501. When the device is in use, the movement of the hinged arc plate 503 can synchronously drive the rotating column 504 to move. During the movement of the rotating column 504, the rotating column 504 will drive the adhesive column 505 to move synchronously. The adhesive column 505 can contact the sample container 2 synchronously while the hinged arc plate 503 applies an expansion force to the inner wall of the sample container 2. According to its own adhesive material, it can stabilize the expansion force of the hinged arc plate 503 on the sample container 2, which can improve the polishing quality of the device and reduce damage during the polishing process. Overall working principle: During the circulation of cooling water in the cooling arc plate 406, the cooling arc plate 406 can cool the surface of the sample bucket 2, gradually reducing the surface temperature. This allows for cooling of the outer surface of the sample bucket 2 before grinding the inner wall, continuously absorbing heat from the outer surface of the plastic bucket to prevent thermal deformation caused by excessively high inner wall temperature. This improves grinding efficiency and quality. The moving scraper ring 411, during its movement, can... The grinding debris adhering to the surface of the grinding roller 10 is scraped off, which improves the service life of the grinding roller 10 and enhances the grinding quality and efficiency of the grinding roller 10. It also prevents the grinding quality from being affected by the debris adhering to the grinding roller 10. It can maintain a relatively equal surface clamping force, which can prevent the sample container 2 from undergoing large deformation during the grinding process, thereby affecting the grinding quality and efficiency of the device. It can stabilize the expansion force of the hinged arc plate 503 on the sample container 2, which can improve the grinding quality of the device and reduce damage during the grinding process.
