Description

Technical Field

[0001] The invention relates to the technical field of burr removal, in particular to a burr removal device for plastic processing. Background Art

[0002] Plastic is a plastic material and its products made of resin as the main component, usually molded by injection molding. After the plastic is molded, some plastic corners will have raised burrs, which need to be processed before use to avoid accidental injury to people. For burrs, the existing technology has special equipment to remove them.

[0003] For example, a patent with patent publication number CN216802844U and publication date 2022-06-24 discloses a deburring device for the production of plastic sheets. The deburring device for the production of plastic sheets requires the plastic sheet to be placed in a limiting groove and then polished with a polishing brush above. If the other side needs to be polished, the plastic sheet needs to be manually taken out and flipped over. The surface to be polished cannot be automatically replaced, and the operation is cumbersome.

[0004] For example, the patent with patent publication number CN211518237U and publication date 2020-09-18 discloses a burr removal mechanism for plastic plate production. The burr removal mechanism for plastic plate production pushes the U-shaped frame to be clamped on the plastic plate by rotating the screw column one, and then rotates the bidirectional screw column to make the scraper touch the edge of the plastic plate. It is necessary to rotate the screw column one and the bidirectional screw column separately, and the clamping adjustment and alignment adjustment cannot be performed synchronously.

[0005] In view of the shortcomings of the above-mentioned prior art, a burr removal device for plastic processing is designed to overcome the shortcomings of the prior art and can automatically replace the surface to be polished, automatically and synchronously align the position to be polished when clamped, and is easy to operate.

[0030] Embodiment 1: A burr removal device for plastic processing, such as Figure 1-Figure 3As shown, it includes a base 1, an adjustment mechanism 2, a grinder 3, an electric guide rail 41, a support member 42, a gear 43, a rack 44, a clamping mechanism 5 and an extrusion assembly 6. The upper part of the base 1 is provided with an adjustment mechanism 2, and the adjustment mechanism 2 is provided with a grinder 3 for removing burrs. The adjustment mechanism 2 can adjust the position of the grinder 3. The upper part of the base 1 is installed with a transversely arranged electric guide rail 41, and a support member 42 for supporting a plastic plate is rotatably provided on the slider of the electric guide rail 41. The lower part of the support member 42 is connected by a single A gear 43 is connected to the coupler, a rack 44 for meshing with the gear 43 is connected to the end of the electric guide rail 41, and the support member 42 drives the plastic sheet to rotate under the action of the gear 43 meshing with the rack 44. The adjusting mechanism 2 is provided with a clamping mechanism 5 for centering and clamping the plastic sheet. The adjusting mechanism 2 synchronously adjusts the clamping mechanism 5 and the grinder 3. An extrusion assembly 6 is provided on the slider of the electric guide rail 41. Before the support member 42 drives the plastic sheet to rotate, the extrusion assembly 6 pre-triggers the clamping mechanism 5 to release the plastic sheet.

[0031] like Figure 2 As shown, the adjustment mechanism 2 includes a guide rod 21, a bidirectional screw rod 22 and a connecting frame 23. The guide rod 21 is connected to the upper left part of the base 1, and the bidirectional screw rod 22 is rotatably provided on the upper right part of the base 1. The guide rod 21 and the bidirectional screw rod 22 are opposite to each other on the left and right. The end of the bidirectional screw rod 22 is connected to a handle for grasping. The front and rear ends of the guide rod 21 are slidably provided with a connecting frame 23 threadedly connected to the bidirectional screw rod 22, and the grinder 3 and the clamping mechanism 5 are both arranged on the connecting frame 23.

[0032] like Figure 2 As shown, the clamping mechanism 5 includes a clamping rod 1 51, a connecting rod 52, a clamping rod 2 53, a sleeve rod 54 and an elastic member 55. The upper right side of the connecting frame 23 is connected to the clamping rod 1 51 in an L-shape, the left side of the connecting frame 23 is connected to the connecting rod 52, the left end of the connecting rod 52 is slidably provided with a clamping rod 2 53 in a T-shape, the clamping rod 2 53 passes through the connecting rod 52, the sleeve rod 54 is sleeved on the middle part of the clamping rod 2 53, and an elastic member 55 surrounding the clamping rod 2 53 is connected between the sleeve rod 54 and the connecting rod 52, and the elastic member 55 is a steel spring.

[0033] like Figure 2 and Figure 4 As shown, the extrusion assembly 6 includes a connecting rod 61, a diagonal rod 62, a torsion spring 63 and a blocking rod 64. Two connecting rods 61 opposite to each other are connected to the slider of the electric guide rail 41. The end of the connecting rod 61 away from the electric guide rail 41 is rotatably provided with a diagonal rod 62 for extruding the sleeve rod 54. The diagonal rod 62 is inclined to the lower right. Two torsion springs 63 opposite to each other and surrounding the connecting rod 61 are connected between the diagonal rod 62 and the connecting rod 61. A blocking rod 64 for blocking one side of the diagonal rod 62 is connected to the end of the connecting rod 61 away from the electric guide rail 41. The blocking rod 64 is located above the diagonal rod 62.

[0034] like Figure 3 As shown, the upper part of the support member 42 is an electric suction cup, and the lower part of the support member 42 is a rotating shaft. The rotating shaft is rotatably arranged on the slider of the electric guide rail 41, and the gear 43 is connected to the rotating shaft.

[0035] When it is necessary to remove the burrs of the plastic sheet, first, place the plastic sheet on the electric suction cup of the support 42, and then rotate the bidirectional screw rod 22, the bidirectional screw rod 22 will drive the connecting frames 23 on the front and rear sides to approach each other, and the connecting frames 23 on the front and rear sides will respectively drive the grinders 3 and the clamping rod 51 on the front and rear sides to approach each other, and the clamping rod 51 will clamp the plastic sheet in the center. At this time, stop rotating the bidirectional screw rod 22, and the grinder 3 will just move to a position where the plastic sheet can be polished, so that it will automatically and synchronously align with the position to be polished when clamping, and then control the electric suction cup of the support 42. The suction cup absorbs the plastic sheet, starts the grinder 3, and then controls the slider of the electric guide rail 41 to drive the support member 42 and the extrusion assembly 6 to move left. The support member 42 will drive the plastic sheet to move left, and the grinder 3 can grind the plastic sheet to remove burrs. When the support member 42 moves left, the gear 43 on the rotating shaft of the support member 42 also moves left. After the plastic sheet is polished, the plastic sheet will move left and will be separated from the clamping rod 1 51 and restricted by the clamping rod 2 53. When the extrusion assembly 6 continues to move left, the blocking rod 64 blocks the upper part of the inclined rod 62, so the inclined rod 62 will squeeze the sleeve rod 54. The sleeve rod 54 moves downward, the elastic member 55 is compressed, and the sleeve rod 54 drives the clamping rod 2 53 to move downward to loosen the plastic plate. At this time, the gear 43 continues to move left to mesh with the rack 44, and the gear 43 drives the plastic plate to rotate ninety degrees through the support member 42, so that after the grinding is completed, the plastic plate is automatically and synchronously loosened and rotated to replace the position where the plastic plate needs to be grinded. After the replacement is completed, the inclined rod 62 continues to move left to loosen the sleeve rod 54, and the elastic member 55 is reset. The sleeve rod 54 will drive the clamping rod 2 53 to move upward and reset under the action of the reset of the elastic member 55, and then the bidirectional screw rod 22 is rotated again to adjust the clamping rod 2 53 is positioned so that the clamping rod 53 can center and clamp the rotated plastic sheet, and at the same time, the grinder 3 can align with the plastic sheet, and then the electric guide rail 41 is controlled to drive the support member 42 and the extrusion assembly 6 to move right, and the support member 42 can drive the plastic sheet and the gear 43 to move right. At this time, the gear 43 will not drive the support member 42, and the inclined rod 62 will pass over the sleeve rod 54 and reset under the action of the torsion spring 63, so that the other two sides of the plastic sheet can be ground. After the grinding is completed, the electric guide rail 41 and the grinder 3 are turned off, and the electric suction cup of the support member 42 can be released.

[0036] Embodiment 2: Based on embodiment 1, Figure 5As shown, it also includes a base plate 71, a bracket 72, a linear guide 73, a clamping cylinder 74, a clamping plate and a second connecting rod 75. The lower side of the base 1 is connected to the base plate 71, and the upper side of the base plate 71 is connected to two brackets 72 opposite to each other on the left and right. A linear guide 73 is connected between the upper parts of the two brackets 72. The right end of the linear guide 73 is slidably provided with a clamping cylinder 74 located directly above the support member 42. A clamping plate for clamping a plastic sheet is rotatably provided on the piston of the clamping cylinder 74. A second connecting rod 75 in a U-shape is connected between the clamping cylinder 74 and the lower part of the support member 42.

[0037] After placing the plastic sheet on the support 42, the clamping cylinder 74 is controlled to drive the clamping plate to move downward to fix the plastic sheet. When the electric guide rail 41 drives the support 42 to move, the support 42 will drive the clamping cylinder 74 to move synchronously through the connecting rod 2 75 to continuously fix the plastic sheet. The plastic sheet can be loosened by controlling the clamping cylinder 74 to drive the clamping plate to move upward.

[0038] Embodiment 3: Based on embodiment 2, Figure 6 As shown, it also includes a support rod 81 and a vortex tube cooler 82. The support rod 81 is connected to the side of the two connecting frames 23 that are away from each other. The end of the support rod 81 away from the connecting frame 23 is bent upward by ninety degrees. The upper end of the support rod 81 is installed with a vortex tube cooler 82. The vortex tube cooler 82 is aimed at the grinder 3. The vortex tube cooler 82 uses cooling to quickly brittle the burrs.

[0039] When the grinder 3 is grinding the plastic plate, the vortex tube cooler 82 is controlled to cool the plastic plate and the grinder 3 , so that the burrs are quickly brittle by cooling, while preventing the grinder 3 from overheating.

[0040] Embodiment 4: Based on the embodiment 3, Figure 7 As shown, it also includes a support rod 91, a pressure rod 92 and a compression spring 93. The grinder 3 is composed of a grinding motor 31, a prismatic rod 32 and a grinding roller 33. The grinding motor 31 is installed on the upper side of the connecting frame 23. The prismatic rod 32 is connected to the output shaft of the grinding motor 31. The grinding roller 33 is slidably sleeved on the prismatic rod 32. The left side of the connecting frame 23 is connected to a vertically arranged support rod 91. The upper end of the support rod 91 is slidably provided with a pressure rod 92 located above the grinding roller 33. The pressure rod 92 is horizontally arranged, and a compression spring 93 surrounding the pressure rod 92 is connected between the pressure rod 92 and the support rod 91.

[0041] The grinding roller 33 of the grinder 3 can be removed from the prismatic rod 32 for replacement. Initially, the pressure rod 92 blocks the grinding roller 33. When the grinding roller 33 needs to be replaced, the pressure rod 92 is driven to move left, the compression spring 93 is compressed, and the pressure rod 92 will release the grinding roller 33. At this time, the grinding roller 33 can be replaced. After the replacement is completed, the pressure rod 92 is released, the compression spring 93 is reset, and the pressure rod 92 will move right and reset under the action of the compression spring 93.

[0042] Embodiment 5: Based on Embodiment 4, Figure 8 As shown, a collection box 10 is also included. The connecting frame 23 is connected to the collection box 10 located below the grinder 3. The collection box 10 is used to collect debris generated by the grinder 3 grinding the plastic sheet. A handle is installed on the collection box 10, which is convenient for users to push and pull.

[0043] The collecting box 10 collects the debris generated by the grinder 3 grinding the plastic sheet, so as to facilitate the recycling of the plastic debris.
