Description

Technical Field

[0001] This invention relates to the field of plastic polishing technology, and specifically proposes a plastic polishing device and method for producing plastic sliders. Background Technology

[0002] Crane plastic sliders are generally made of ultra-high molecular weight polyethylene, a very wear-resistant material that also has its own lubricating properties. When used as sliders to accompany machinery during operation, they can reduce the friction between the slider and the crane's telescopic boom, thereby improving the crane boom's sliding and lifting capacity. To ensure a smooth surface for the plastic sliders, they need to be polished after production.

[0003] However, the following problems still exist in the process of polishing plastic sliders: 1. When polishing plastic sliders, different angles of inclination of the stepped slope of the plastic slider are required. Traditional tools are generally only suitable for polishing plastic sliders of the same specification and angle, which greatly reduces the applicability of the device.

[0004] 2. After grinding the plastic slider, it needs to be unloaded. After unloading, the plastic slider to be ground is loaded to complete the grinding of the next set of plastic sliders. Loading and unloading wastes time and cannot achieve uninterrupted grinding of plastic sliders, thus reducing the working efficiency of grinding plastic sliders.

[0005] Therefore, in order to improve the applicability of the device and enhance its work efficiency, this invention provides a plastic grinding device for producing plastic sliders. Summary of the Invention

Detailed Implementation

[0036] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] See Figure 1 A plastic grinding device for producing plastic sliders includes a worktable 1. A fixing mechanism 2 for fixing the plastic slider is provided on the top of the worktable 1 near the rear side, and a grinding mechanism 3 for grinding the inclined surface of the plastic slider is provided on the top of the worktable 1 at the front side.

[0038] See Figure 1 , Figure 4 and Figure 5 The fixing mechanism 2 includes T-shaped fixing plates 21 symmetrically fixed to the top left and right sides of the workbench 1. The horizontal sections of the two fixing plates 21 have moving grooves on their opposite sides. Each moving groove is slidably connected to an extension plate 22 via a first electric slider. The front and rear side walls of the extension plate 22 are symmetrically provided with two sets of fixing chains 23. Each fixing chain 23 includes a rectangular plate 24 fixedly installed on the extension plate 22. The bottom of the rectangular plate 24 is provided with a rectangular groove near the right side. A moving block 26 is slidably connected to the rectangular groove via a return spring 25. The bottom of the moving block 26 is provided with a clamping component 28 for fixing the plastic slider via a connecting component 27. The horizontal section of the left fixing plate 21 is provided with a drive component 29 for controlling the left and right reciprocating movement of the moving block 26 near the front.

[0039] In the initial state, the plastic sliders to be polished are first placed in batches onto the clamping assembly 28, and quickly clamped and fixed by the clamping assembly 28 to prevent the plastic sliders from moving during the polishing process and affecting the polishing. Next, the first electric slider is activated, causing the extension plate 22 to drive the two sets of fixed supports 23 to move forward simultaneously, so that the multiple clamped plastic sliders move to directly above the polishing mechanism 3. At this time, the polishing mechanism 3 is adjusted according to the different angles of the inclined surfaces of the plastic sliders to be polished. After adjustment, the polishing mechanism 3 contacts the inclined surfaces of the plastic sliders, and then the connecting assembly 27 is used to... After being clamped on the moving clamping assembly 28, the plastic slider moves back and forth and completes the grinding of the inclined surface of the plastic slider. After grinding, the grinding mechanism 3 is adjusted, and finally the moving block 26 is moved left and right by the set driving assembly 29. The moving block 26 causes the clamping assembly 28 on the connecting assembly 27 to drive the horizontal surface of the clamped plastic slider to grind left and right. At the same time as grinding, the plastic slider to be ground is placed on the second set of fixed support chains 23. Through the two sets of fixed support chains 23, the plastic slider can be ground continuously, which improves the efficiency of grinding the plastic slider and enhances the grinding effect.

[0040] See Figure 4 and Figure 5The connecting component 27 includes a displacement groove at the bottom of the moving block 26. A mounting block 271 is slidably connected in the displacement groove by a second electric slider that slides back and forth. A stabilizing plate 272 is fixedly installed at the bottom of the mounting block 271. A rotating rod 273 is rotatably mounted on the stabilizing plate 272. The right end face of the rotating rod 273 passes through the stabilizing plate 272. A forward and reverse motor is fixedly installed on the right side of the stabilizing plate 272 by a motor base. The output shaft of the forward and reverse motor is fixedly connected to the right end face of the rotating rod 273.

[0041] Continue reading Figure 4 and Figure 5 The clamping assembly 28 includes a first clamping plate 281 uniformly fixedly installed from left to right on the bottom of the stabilizing plate 272. Multiple sliding grooves are provided on the bottom of the stabilizing plate 272 on the right side of the first rectangular plate 24. A second clamping plate 282 is horizontally slidably arranged within these sliding grooves. Circular through slots are provided on the second clamping plate 282 at positions relative to the suspension rod 283. The section of the rotating rod 273 located within the sliding groove is threaded and threadedly connected to the second clamping plate 282. The right end face of the first clamping plate 281 is uniformly fixedly installed from top to bottom with... The suspension rod 283 has a tapered structure with a small diameter end pointing to the right on its right end. The opposing surfaces of the first clamping plate 281 and the second clamping plate 282 are provided with fixing grooves, and anti-slip pads are installed in the fixing grooves. Cooling plates 284 for cooling are fixedly installed at the bottom of the opposing surfaces of the first clamping plate 281 and the second clamping plate 282. The cooling plates 284 installed on the first clamping plate 281 and the second clamping plate 282 can cool down the plastic slider and prevent the grinding effect from being affected by excessive temperature during the grinding process of the plastic slider.

[0042] In the initial state, the plastic sliders to be ground are first placed in batches onto the suspension rods 283 on the first clamping plate 281. The right end of the suspension rod 283 has a tapered structure, serving as a guide and facilitating insertion into the circular slots on the second clamping plate 282. After all sliders are placed, the forward and reverse motor is started, rotating the rotating rod 273. The rotating rod 273 moves the second clamping plate 282 closer to the first clamping plate 281, quickly clamping and fixing the plastic sliders. Anti-slip pads fixed on the first and second clamping plates 281 increase friction, better limiting and fixing the plastic sliders, preventing movement during grinding and affecting the process. The grinding mechanism 3 and the inclined surface of the plastic sliders are then utilized. After contact, the second electric slider is activated. The second electric slider causes the stabilizing plate 272 on the mounting block 271 to drive the clamped plastic slider to reciprocate back and forth, completing the grinding of the inclined surface of the plastic slider. Finally, the driving component 29 is used to grind the horizontal surface of the plastic slider. After all grinding is completed, the first electric slider is activated again, causing the extension plate 22 to drive the two sets of fixed supports 23 to continue moving forward. This causes the plastic slider clamped on the latter set of fixed supports 23 to move to the top of the grinding mechanism 3, and the ground plastic slider to move to the front. At this time, the forward and reverse motor is activated to reverse the direction, so that the second clamping plate 282 no longer clamps the plastic slider, and the ground plastic slider can be unloaded. After unloading, loading continues, thus achieving uninterrupted grinding of the plastic slider.

[0043] See Figure 1 and Figure 2 The drive assembly 29 includes a movable column 291 slidably connected to the left fixed plate 21. A push plate 292 is fixedly installed on the movable column 291 at the left side of the fixed plate 21. The push plate 292 and the fixed plate 21 are fixedly connected by a movable spring 293. A drive motor is fixedly installed on the fixed plate 21 by a motor mount. An eccentric wheel 294 that controls the reciprocating motion of the push plate 292 is fixedly installed on the lower output shaft of the drive motor.

[0044] When the extension plate 22 drives the two sets of fixed support chains 23 to move forward simultaneously, and the plastic slider after being clamped by the first set moves to the top of the grinding mechanism 3, the left end face of the moving column 291 and the moving block 26 comes into contact. After the plastic slider is ground back and forth using the set connecting component 27, the drive motor is started. When the drive motor causes the highest point of the eccentric wheel 294 to contact the push plate 292, the push plate 292 causes the moving column 291 to press the moving block 26 to the right. When the lowest point of the eccentric wheel 294 contacts the push plate 292, the return spring 25 causes the moving block 26 to return to its original position. At the same time, the moving spring 293 keeps the push plate 292 in contact with the side wall of the eccentric wheel 294, thereby completing the left and right reciprocating grinding of the plastic slider.

[0045] See Figure 1 Figure 3 and Figure 4 The grinding mechanism 3 includes a support plate 31 fixedly installed on the top of the workbench 1 by a cylinder. The four corners of the bottom of the support plate 31 are fixedly connected to the workbench 1 by spring rods 32. Multiple C-shaped plates 33 with openings facing left are evenly fixedly installed on the top of the support plate 31 from left to right. An adjustment plate 34 is hinged to the left opening end of the C-shaped plate 33 at the upper position by a pin. A grinding plate 35 is detachably connected to the top of the adjustment plate 34. A moving component 36 for adjusting the angle of the adjustment plate 34 is provided on the C-shaped plate 33.

[0046] When the clamped plastic slider moves to the top of the grinding mechanism 3, the angle of the adjusting plate 34 is adjusted accordingly by the moving component 36 so that the angle of the inclined surface of the plastic slider to be ground varies. This causes the adjusting plate 34 to move the grinding plate 35 to a suitable angle, thereby increasing the applicability of the grinding device. Finally, the cylinder is activated so that the support plate 31 moves upward, and the support plate 31 brings the grinding plate 35 on the adjusting plate 34 into contact with the inclined surface of the plastic slider.

[0047] See Figure 3 , Figure 5 and Figure 6The moving component 36 includes extension blocks 361 that are symmetrically and fixedly connected to the bottom of the adjusting plate 34. A swing plate 362 is hinged between the two extension blocks 361 by a pin. A rectangular through groove is opened on the opposite surface of the two horizontal sections of the C-shaped plate 33. An installation plate 363 is slidably arranged in the rectangular through groove. A square block 364 is symmetrically and fixedly installed on the left side of the installation plate 363. The two square blocks 364 are hinged to one end of the swing plate 362 by a pin. The rear end faces of multiple installation plates 363 all pass through the rectangular through groove and are fixedly connected by a connecting plate 365. An electric telescopic rod fixedly connected to the installation plate 363 is fixedly installed on the vertical end of the leftmost C-shaped plate 33. A receiving plate 366 is fixedly installed on the opposite surface of the two horizontal sections of the C-shaped plate 33 above the rectangular through groove.

[0048] When the angle of the inclined surface of the plastic slider to be ground varies, the angle of the adjusting plate 34 is adjusted accordingly. The specific adjustment method is as follows: the electric telescopic rod is activated, which causes the mounting plate 363 to move to the left or right, thereby causing the square block 364 to drive multiple swing plates 362 to move simultaneously at a certain angle, thus completing the angle adjustment of the adjusting plate 34. After the plastic slider is reciprocated for grinding using the set connecting component 27, the electric telescopic rod is activated, causing the mounting plate 363 to move to the right. The swing plates 362 on the mounting plate 363 cause the adjusting plate 34 to change from an inclined state to a horizontal state. At this time, the setting receiving plate 366 supports and limits the adjusting plate 34. Then, the cylinder is activated again, so that the grinding plate 35 on the adjusting plate 34 comes into contact with the horizontal surface of the plastic slider, thus facilitating the grinding of the horizontal surface of the plastic slider.

[0049] See Figure 6 and Figure 7 The top of the adjusting plate 34 is provided with a clamping groove, and a rectangular clamping block 341 is detachably connected in the clamping groove. The top of the rectangular clamping block 341 is fixedly connected to the bottom of the grinding plate 35. Both sides of the rectangular clamping block 341 are provided with multiple clamping slots arranged vertically in a semi-arc structure. The end face of the clamping groove is symmetrically provided with multiple placement slots corresponding to the clamping slots. A rectangular block 343 is slidably connected in the placement slot through a compression spring 342. A semi-arc groove is provided at the end of the rectangular block 343 away from the compression spring 342. A clamping ball 344 is rolled in the semi-arc groove.

[0050] When the grinding plate 35 needs to be replaced, pull the grinding plate 35 upward. At this time, the locking ball 344 on the rectangular block 343 in the groove disengages from the slot on the rectangular block 341, and the grinding plate 35 can be quickly removed. When a new grinding plate 35 needs to be installed, slide the rectangular block 341 at the bottom of the grinding plate 35 into the locking groove. At this time, under the reaction force of the compression spring 342, the locking ball 344 on the rectangular block 343 is locked into the slot on the rectangular block 341, thereby limiting the rectangular block 341.

[0051] See Figure 5 A container 331 is provided on the left side of the opening end of the shaped plate 33, and the inner sidewall of the container 331 near the end of the shaped plate 33 gradually slopes to the left from top to bottom.

[0052] The collection box 331, whose inner wall is set to gradually tilt to the left from top to bottom near the C-shaped plate 33, can collect the grinding debris on the plastic slider when the grinding plate 35 is tilted. This prevents the debris from falling directly onto the worktable 1, which is difficult to clean and will also have a certain impact on the working environment.

[0053] The present invention also provides a plastic polishing method for producing plastic sliders, comprising the following steps: S1, fixing the plastic sliders: First, the plastic sliders to be polished are placed in batches on the suspension rods 283 on the first clamping plate 281. After all are placed, the forward and reverse motor is started to rotate forward. The forward and reverse motor drives the rotating rod 273 to rotate. The rotating rod 273 causes the second clamping plate 282 to move closer to the first clamping plate 281 and quickly clamps and fixes the plastic sliders. Next, the first electric slider is started, so that the extension plate 22 drives the two sets of fixed supports 23 to move forward at the same time, and so that the multiple clamped plastic sliders move to the top of the polishing mechanism 3.

[0054] S2. Adjusting the angle: After step S1 is completed, the angle of the adjusting plate 34 is adjusted according to the different angles of the inclined surface of the plastic slider to be ground. The specific adjustment method is as follows: start the electric telescopic rod, which causes the mounting plate 363 to move to the left or right, thereby causing the square block 364 to drive multiple swing plates 362 to move at the same time by a certain angle, thereby completing the angle adjustment of the adjusting plate 34 and making the grinding plate 35 contact the inclined surface of the plastic slider.

[0055] S3. Grinding the plastic slider: After step S2 is completed, start the second electric slider. The second electric slider causes the stabilizing plate 272 on the mounting block 271 to drive the clamped plastic slider to move back and forth, and to grind the inclined surface of the plastic slider. Then, the driving component 29 is used to make the moving block 26 move left and right. The moving block 26 causes the clamping component 28 on the connecting component 27 to drive the horizontal surface of the clamped plastic slider to grind left and right.

[0056] S4. Unloading the plastic slider: After step S3 is completed and all grinding is finished, start the first electric slider again, so that the extension plate 22 drives the two sets of fixed support chains 23 to continue moving forward, so that the plastic slider clamped on the second set of fixed support chains 23 moves to the top of the grinding mechanism 3, and so that the ground plastic slider moves to the front. At this time, start the forward and reverse motor to reverse, so that the second clamping plate 282 no longer clamps the plastic slider, and the ground plastic slider can be unloaded. After unloading, continue loading, and thus achieve uninterrupted grinding of the plastic slider.
