[0027] The embodiment of the present application discloses a polishing device for an injection-molded plastic cylinder. Through the setting of the steering mechanism 5, when the lifting connecting plate 302 drives the polishing mechanism 4 to lift and lower to polish the welding mark on the outside of the plastic cylinder 7, it will contact the second moving block 5032 and the stabilizing guide shell 5023 in the steering mechanism 5, thereby rotating the gear 501, and then driving the rotating connecting column 205, the pressure guiding column 202, the pressure platform 204 and the plastic cylinder 7 to rotate together, thereby realizing automatic and precise steering and improving the polishing efficiency of the plastic cylinder 7.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Example 1: Reference Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 The present application discloses a polishing device for an injection-molded plastic cylinder, comprising a pre-clamping mechanism 2, which is arranged at the bottom end and both sides of a polishing table 1, a polishing mechanism 4, which is arranged on one side above the polishing table 1, and is used to polish the welding marks on the outside of the plastic cylinder 7, a steering mechanism 5, which is arranged below the polishing table 1, and is suitable for rotating the direction of the plastic cylinder 7 under the lifting drive of the polishing mechanism 4, and the steering mechanism 5 comprises a rotating gear 501, and the outer side of the rotating gear 501 is symmetrically meshed with a first tooth plate 502 and a second tooth plate 503, and one side of the first tooth plate 502 is fixedly provided with a first connecting frame 5021, and the first connecting frame 5021 is fixedly provided with a first connecting frame 5022. A first movable block 5022 is fixedly provided at the top of a connecting frame 5021, a second connecting frame 5031 is fixedly provided on one side of the second tooth plate 503, a second movable block 5032 is fixedly provided on one side of the top of the second connecting frame 5031, a rotating connecting column 205 is fixedly provided on the inner side of the rotating gear 501, a guide pressure column 2043 is slidably provided on the inner side of the other end of the rotating connecting column 205, a pressing platform 204 is fixedly provided on one end of the guide pressure column 2043, a plastic cylinder 7 is located at the top of the pressing platform 204, a fixed slide rod 5033 is penetrated and slidably provided on one side of the second connecting frame 5031, and fixed connecting frames 5034 are fixedly provided at both ends of the fixed slide rod 5033, and the fixed connecting frames 5034 can be The first tooth plate 502 and the second tooth plate 503 are slidably provided with a hanger 504 on the outer side, and the hanger 504 is detachably provided at the bottom end of the grinding table 1. The top side of the first movable block 5022 and the bottom side of the second movable block 5032 are inclined. The stable guide shell 5023 is detachably provided at the bottom end of the protective shell 303. The other end of the rotating connecting column 205 is fixedly provided with a connecting plate 505. The bottom side of the connecting plate 505 is fixedly provided with a sliding column 506. The outer side of the sliding column 506 is slidably provided with a limited arc frame 508. The other end of the sliding column 506 is fixedly provided with a fixed slide plate 507. The bottom of the fixed slide plate 507 is fixedly provided with a sliding column 506. A short-circuit slide column 509 is slidingly provided at the end, a follow-up column 510 is fixedly provided at one end of the short-circuit slide column 509, a guide rail frame 511 is slidingly provided on the outer side of the follow-up column 510, a connecting support plate 512 is fixedly provided at the other end of the follow-up column 510, a hanging plate 515 is fixedly provided at the bottom end of the connecting plate 505, a locking spring 513 and a reinforced telescopic rod 514 are fixedly provided between the connecting support plate 512 and the hanging plate 515, a stabilizing frame 5081 and a connecting bracket 5110 are fixedly provided on the outer sides of the limiting arc frame 508 and the guide rail frame 511 respectively, the connecting bracket 5110 is detachably provided at the bottom end of the grinding table 1, and the stabilizing frame 5081 is detachably provided at the bottom end of the grinding table 1.

[0030] As the top pressure block 401 rises to the highest point, it will contact the second movable block 5032, so that the second movable block 5032 can move to one side, and at the same time drive the first tooth plate 502 to move, and the first tooth plate 502 will drive the rotating gear 501 to rotate. The rotation of the rotating gear 501 drives the rotating connecting column 205, the pressure guiding column 202 and the pressing platform 204 to rotate together, so that the plastic tube 7 on the top of the pressing platform 204 can be rotated in a direction so that another welding mark can be located at the position of the grinding wheel 412, thereby realizing automatic and precise steering and improving the grinding efficiency of the plastic tube 7. Before this, the clamping state of the pre-clamping mechanism 2 needs to be unlocked by the unlocking component 6.

[0031] It should be noted that after the current plastic tube 7 is polished, a new plastic tube 7 is placed. When the lifting connecting plate 302 drives the top pressing block 401 to drop to the lowest point, the top pressing block 401 will contact the first movable block 5022 and move the first movable block 5022 to one side, and the rotating gear 501 drives the rotating connecting column 205 to rotate ninety degrees in the opposite direction, so that other plastic tubes 7 can be turned.

[0032] When the rotating connecting column 205 rotates, the rotating plate 505 and the hanging plate 515 will rotate at the same time, so that the sliding column 506 can move inside the limit arc frame 508. The limit arc frame 508 is used to limit the maximum rotation angle of the rotating connecting column 205, and the maximum rotation angle is ninety degrees. At the same time, the sliding column 506 will drive the fixed slide plate 507, the short-circuit sliding column 509 and the follow-up column 510 to move, and the follow-up column 510 will move inside the guide frame 511, which is set at a right angle. When the follow-up column 510 moves to the right angle of the guide rail frame 511, the length of the locking spring 513 and the enhanced telescopic rod 514 will be extended to the maximum. At this time, the locking spring 513 is in an extended state. As the follow-up column 510 moves, the locking spring 513 and the enhanced telescopic rod 514 will slowly return to their original positions, thereby preventing the rotating connecting column 205 from rotating easily and improving the stability of the plastic tube 7 during grinding. The short-circuit slide column 509 will move at the bottom end of the fixed slide plate 507 to adapt to the movement of the follow-up column 510.

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The pre-clamping mechanism 2 includes a fixed tube 201, two fixed tubes 201 are symmetrically arranged, the fixed tube 201 is fixedly arranged at the bottom end of the grinding table 1, one end of the fixed tube 201 is slidably connected with a pressure-guiding column 202, the pressure-guiding column 202 passes through and is slidably arranged at the top of the grinding table 1, and a ring sliding column 203 is fixedly arranged at the top of the pressure-guiding column 202, and a fixed flange 2011 is fixedly arranged at the other end of the fixed tube 201, and a pneumatic column 207 is slidably arranged inside the other end of the fixed tube 201, and an adjusting screw 208 is threadedly connected to the inner side of one end of the pneumatic column 207, and the adjusting screw 2 A turntable 212 is fixedly provided at one end of 08, a clamping plate 213 is rotatably provided at the other end of the turntable 212, a protective clamping pad 214 is fixedly provided on the other side of the clamping plate 213, a fixing ring 210 is rotatably provided at one end of the turntable 212, a return spring 209 is fixedly provided on the other end face of the fixing ring 210, the return spring 209 is fixedly provided on the end face of the fixing flange 2011, a guide slide plate 211 is fixedly provided on the outer side of the fixing ring 210, the guide slide plate 211 is slidably provided on the outer side of the fixing flange 2011, and the ring sliding column 203 is slidably provided on the inner side of the bottom sliding rail 2042.

[0034] The plastic tube 7 is placed on the top of the pressing platform 204 in the pre-clamping mechanism 2, and then the plastic tube 7 is pressed down to make the pressing platform 204 drop, and the annular sliding column 203 will be embedded into the interior of the grinding table 1, and at the same time press the air inside the fixed tube 201 to make the air inside it flow, and the pneumatic column 207 will be pushed by the air, so that the clamping plates 213 are close to each other, so that the clamping plates 213 clamp and fix the plastic tube 7 through the protective clamping pad 214 to prevent it from moving during grinding. While the protective clamping pad 214 is clamping, the return spring 209 is in a compressed state, which can provide elastic force for the protective clamping pad 214 to make the clamping more stable, and when the plastic tube 7 is taken out, the pneumatic column 207 returns to its original position, thereby making the pressure-guiding column 202 and the pressing platform 204 return to their original positions.

[0035] When it is necessary to clamp plastic tubes 7 of different diameters, the fixing tube 201 can be rotated to rotate the adjusting screw 208, thereby changing the total length between the adjusting screw 208 and the pneumatic column 207, so that the two sets of protective pads 214 can clamp and fix plastic tubes 7 of different diameters.

[0036] In this embodiment, the total length of the adjusted pneumatic column 207 and the adjusting screw 208 will not affect the length of the pneumatic column 207 inside the fixed tube 201, that is, the length of the fixed tube 201 exposed to the outside will not change, and will not affect the clamping effect of the clamping plate 213 and the protective clamping pad 214.

[0038] When the press table 204 rotates, the annular sliding column 203 will slide in the bottom sliding rail 2042, and the fixed side frame 607 will slide inside the outer annular sliding rail 2041, without affecting the use of other components.

A limit slider 609 is provided, and the limit slider 609 is fixedly set on both sides of the grinding table 1. Symmetrical thread lines are set on the outer sides of both ends of the threaded rod 6011. A long sliding rod 606 is penetrated and slidably set on one side of the driving plate 602.

The bottom end side of the fixed locking block 608 is set as an inclined surface, and the top end side of the movable locking block 604 is set as an inclined surface.

[0040] When the clamping state of the plastic tube 7 is unlocked, the grinding motor 601 in the unlocking component 6 is started to rotate the threaded rod 6011, and the driving plate 602 will move away from each other, and drive the movable locking block 604 and the stabilizing slide rail 605 to move, and the stabilizing slide rail 605 will leave the fixed locking block 608, so that the fixed side frame 607 can rise freely, so that the pre-clamping mechanism 2 can achieve the unlocking effect, and then the driving plate 602 returns to its original position.

[0041] Among them, when the fixed side frame 607 descends, the movable locking block 604 will move to one side, and the force spring 603 will be compressed. The elastic force of the force spring 603 will make the movable locking block 604 engage with the top of the fixed locking block 608, completing the locking effect, preventing the fixed side frame 607 and the pressure platform 204 from rising, thereby preventing the pre-clamping mechanism 2 from losing the clamping effect, and when the pressure platform 204 rotates, the fixed side frame 607 will not affect its rotation effect.

There is a moving slide 405, a moving slide column 407 is fixedly provided on one side of the moving slide 405, a driving rail frame 408 is slidably provided on the outer side of the moving slide column 407, and the driving rail frame 408 is set in a side "W" shape, a sliding shell 406 is slidably provided on the outer side of the moving slide 405, and a side fixed slide 4061 is fixedly provided on the other side of the sliding shell 406, and the side fixed slide 4061 is slidably set on one side of the protective shell 303, and a fixed rail frame 4081 is detachably provided on one side of the driving rail frame 408, and the fixed rail frame 4081 is detachably set on the top of the grinding table 1, and a grinding frame 410 is fixedly provided on the other end of the electric telescopic rod 409, and a grinding motor 411 is fixedly provided on one side of the grinding frame 410, and a grinding wheel 412 is fixedly provided on the driving end of the grinding motor 411, and the grinding wheel 412 is rotatably set on the inner side of the grinding frame 410.

[0043] When performing the grinding work, the grinding motor 411 in the grinding mechanism 4 is started, and the grinding motor 411 can drive the grinding wheel 412 to rotate, so that the welding mark on the outside of the plastic tube 7 can be polished, and the servo motor 3 is started at the same time to rotate the lifting screw 301. The rotation of the lifting screw 301 can drive the lifting connecting plate 302 to rise and fall. The lifting connecting plate 302 will drive the top pressure block 401 and the anti-slip slide rail 404 to move and rise during the rising process, and through the setting of the connecting block 403, the anti-slip slide rail 404, the sliding column 407 and the electric telescopic rod 409, the grinding motor 411 is driven to rise together. At the same time, the sliding column 407 will move along its path on the inner side of the driving rail frame 408, so that the grinding wheel 412 can produce a lateral grinding effect while rising to smooth the burrs at the welding mark, thereby improving the grinding quality.

[0044] Working principle: place the plastic tube 7 on the top of the pressing platform 204 in the pre-clamping mechanism 2, and then press down the plastic tube 7 to make the pressing platform 204 drop, and the annular sliding column 203 will be embedded into the interior of the grinding table 1, and at the same time press the air inside the fixed tube 201 to make the air inside it flow, and the pneumatic column 207 will be pushed by the air, so that the clamping plates 213 are close to each other, so that the clamping plates 213 clamp and fix the plastic tube 7 through the protective clamping pad 214 to prevent it from moving during grinding. While the protective clamping pad 214 is clamping, the return spring 209 is in a compressed state, which can provide elastic force for the protective clamping pad 214 to make the clamping more stable, and when the plastic tube 7 is taken out, the pneumatic column 207 returns to its original position, thereby making the pressure-guiding column 202 and the pressing platform 204 return to their original positions.

[0045] When it is necessary to clamp plastic tubes 7 of different diameters, the fixing tube 201 can be rotated to rotate the adjusting screw 208, thereby changing the total length between the adjusting screw 208 and the pneumatic column 207, so that the two sets of protective pads 214 can clamp and fix plastic tubes 7 of different diameters.

[0046] When performing the grinding work, the grinding motor 411 in the grinding mechanism 4 is started, and the grinding motor 411 can drive the grinding wheel 412 to rotate, so that the welding mark on the outside of the plastic tube 7 can be polished, and the servo motor 3 is started at the same time to rotate the lifting screw 301. The rotation of the lifting screw 301 can drive the lifting connecting plate 302 to rise and fall. The lifting connecting plate 302 will drive the top pressure block 401 and the anti-slip slide rail 404 to move and rise during the rising process, and through the setting of the connecting block 403, the anti-slip slide rail 404, the sliding column 407 and the electric telescopic rod 409, the grinding motor 411 is driven to rise together. At the same time, the sliding column 407 will move along its path on the inner side of the driving rail frame 408, so that the grinding wheel 412 can produce a lateral grinding effect while rising to smooth the burrs at the welding mark, thereby improving the grinding quality.

[0047] When the top pressure block 401 rises to the highest point, it will contact the second movable block 5032, so that the second movable block 5032 can move to one side, and at the same time drive the first tooth plate 502 to move, and the first tooth plate 502 will drive the rotating gear 501 to rotate. The rotation of the rotating gear 501 drives the rotating connecting column 205, the pressure guiding column 202 and the pressing platform 204 to rotate together, so that the plastic tube 7 on the top of the pressing platform 204 can be rotated in a direction so that another welding mark can be located at the position of the grinding wheel 412, thereby realizing automatic and precise steering and improving the grinding efficiency of the plastic tube 7. Before this, the clamping state of the pre-clamping mechanism 2 needs to be unlocked by the unlocking component 6.

[0048] When the rotating connecting column 205 rotates, the connecting plate 505 and the hanging plate 515 will rotate at the same time, so that the sliding column 506 can move inside the limit arc frame 508. The limit arc frame 508 is used to limit the maximum rotation angle of the rotating connecting column 205. The maximum rotation angle is ninety degrees. At the same time, the sliding column 506 drives the fixed slide plate 507, the short-circuit sliding column 509 and the follow-up column 510 to move. The follow-up column 510 will move inside the guide frame 511, which is set at a right angle. When the follow-up column 510 moves to the right angle of the guide rail frame 511, the length of the lock spring 513 and the enhanced telescopic rod 514 will be extended to the maximum. At this time, the lock spring 513 is in an extended state. As the follow-up column 510 moves, the lock spring 513 and the enhanced telescopic rod 514 will slowly return to their original positions, thereby preventing the rotating connecting column 205 from rotating easily and improving the stability of the plastic tube 7 during grinding. The short-circuit slide column 509 will move at the bottom end of the fixed slide plate 507 to adapt to the movement of the follow-up column 510.

[0049] It should be noted that after the current plastic tube 7 is polished, a new plastic tube 7 is placed. When the lifting connecting plate 302 drives the top pressing block 401 to drop to the lowest point, the top pressing block 401 will contact the first movable block 5022 and move the first movable block 5022 to one side, and the rotating gear 501 drives the rotating connecting column 205 to rotate ninety degrees in the opposite direction, so that other plastic tubes 7 can be turned.

[0050] When the clamping state of the plastic tube 7 is unlocked, the grinding motor 601 in the unlocking component 6 is started to rotate the threaded rod 6011, and the driving plate 602 will move away from each other, and drive the movable locking block 604 and the stabilizing slide rail 605 to move, and the stabilizing slide rail 605 will leave the fixed locking block 608, so that the fixed side frame 607 can rise freely, so that the pre-clamping mechanism 2 can achieve the unlocking effect, and then the driving plate 602 returns to its original position.

[0051] Among them, when the fixed side frame 607 descends, the movable locking block 604 will move to one side, and the force spring 603 will be compressed. The elastic force of the force spring 603 will make the movable locking block 604 engage with the top of the fixed locking block 608, completing the locking effect, preventing the fixed side frame 607 and the pressure platform 204 from rising, thereby preventing the pre-clamping mechanism 2 from losing the clamping effect, and when the pressure platform 204 rotates, the fixed side frame 607 will not affect its rotation effect.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
