Description

Technical Field

[0001] This utility model relates to the field of plastic products technology, and in particular to a burr-resistant plastic product. Background Technology

[0002] Plastic products are a general term for household and industrial products made primarily from plastics. This includes products manufactured using processes such as injection molding and thermoforming. Plastics are a type of ductile synthetic polymer material. They are made primarily of natural or synthetic resins with various additives, and can be molded into specific shapes under certain temperature and pressure conditions, maintaining their shape at room temperature. After production in a mold, plastic products often have burrs remaining on their edges and corners.

[0003] A search revealed that patent CN219445846U discloses a mold for deburring plastic products, belonging to the field of deburring technology for plastic products. The mold includes a processing table with a rectangular groove inside. A first threaded rod is rotatably connected inside the rectangular groove. A movable plate is threadedly connected to the surface of the first threaded rod. A first electric telescopic rod is fixedly installed on the top of the movable plate, and a deburring plate is fixedly installed on the top of the first electric telescopic rod. This allows the two clamping plates to clamp and limit the two sides of the plastic product firstly, driven by the rotation of the bidirectional threaded rod. Then, a worm gear drives a rotating shaft to rotate, causing the limiting plate to rotate at an angle. This rotation adjusts the angle of the plastic product inside the limiting plate. Finally, the first threaded rod drives the deburring plate to move horizontally, and the first electric telescopic rod adjusts the vertical height of the deburring plate, facilitating the mechanical removal of burrs from the surface of the plastic product.

[0004] However, while existing plastic products can effectively remove burrs around their edges using deburring knives, incomplete burr removal often occurs, resulting in insufficient polishing and a burr-like feel remaining around the edges. This reduces the effectiveness of deburring and fails to meet user needs. Therefore, a burr-resistant plastic product is required. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figure 1-3 As shown in the figure, an anti-burr plastic product includes a placement rack 1. An electric push rod 2 is fixedly connected to the top of the placement rack 1. One end of the electric push rod 2 is fixedly connected to a positioning plate 3 that is slidably connected to the top of the placement rack 1. A slide rail rod 4 that is slidably connected to the top of the placement rack 1 is fixedly connected to the outer wall of the positioning plate 3. A plastic product 5 located on one side of the positioning plate 3 is placed on the outer wall of the placement rack 1. An adjustment assembly 6 is provided at the bottom of the placement rack 1. The adjustment assembly 6 includes a first threaded rod 61 that is rotatably connected to the bottom of the placement rack 1, and a first servo motor 62 for driving the first threaded rod 61 to rotate. An adjustment rod 63 that is slidably connected to the bottom of the placement rack 1 is threadedly connected to the outer wall of the first threaded rod 61. A groove 64 is provided at the connection between the bottom of the placement rack 1 and the adjustment rod 63. A second threaded rod 65 is rotatably connected to the outer wall of the adjustment rod 63. One end of the second threaded rod 65 is fixedly connected to a second servo motor 66. A slide rail 67 that is slidably connected to the outer wall of the placement rack 1 is threadedly connected to the outer wall of the second threaded rod 65.

[0022] Among them, as Figure 3 shown, the sliding grooves 64 are symmetrically arranged at both ends of the adjusting rod 63. The adjusting rod 63 forms a sliding structure with the sliding grooves 64 through the first threaded rod 61, which is beneficial to the rotation of the first threaded rod 61, driving the adjusting rod 63 to slide along the inner wall of the sliding groove 64, and playing a role in driving the sliding rod 67 to slide in the vertical direction.

[0023] Among them, as Figure 3 shown, the movement trajectory of the adjusting rod 63 is in the shape of a "square", which is beneficial to the all-round grinding of the four sides of the plastic product by setting the movement trajectory of the adjusting rod 63 in the shape of a "square".

[0024] Among them, as Figure 3 shown, a connecting groove in the shape of a "square" is formed on the surface of the placement rack 1. The sliding rod 67 forms a sliding structure with the placement rack 1 through the second threaded rod 65, which is beneficial to the rotation of the second threaded rod 65, driving the sliding rod 67 to slide along the outer wall of the placement rack 1, and playing a role in driving the grinding roller 74 to perform a horizontal grinding movement.

[0025] Embodiment 2

[0026] As Figure 1-4 shown, this embodiment further illustrates Embodiment 1. A control box 7 is fixedly connected to the top of the sliding rod 67. A worm 71 is rotatably connected to the inner wall of the control box 7. One end of the worm 71 is fixedly connected to a third servo motor 72. A worm gear 73 that is rotatably connected to the inner wall of the control box 7 meshes with the outer wall of the worm 71. The rotation center of the worm gear 73 is fixedly connected to a grinding roller 74 located on one side of the plastic product 5 through a rotating shaft. By setting the grinding roller 74, when the plastic product is being produced and processed, in order to improve the smoothness of the surface of the plastic product after processing, reduce the accidental injury of the burrs on the surface of the plastic product to the staff and reduce the processing quality of the product, after the burrs on the surface of the plastic product are initially removed, the product can be placed on the surface of the device, the electric push rod 2 is opened to drive the positioning plate 3 to fix the plastic product, and the first servo motor 62 and the second servo motor 66 are opened to drive the grinding roller 74 to perform a reciprocating grinding movement along the four sides of the plastic product through the "square"-shaped movement trajectory of the adjusting rod 63, playing a role in improving the grinding smoothness of the surface of the plastic product ⑤ after initial deburring.

[0027] Among them, as Figure 4 shown, the rotation center of the worm gear 73 and the rotation center of the grinding roller 74 are arranged to coincide with each other. The grinding roller 74 forms a rotating structure with the worm 71 through the worm gear 73, which is beneficial to the rotation of the worm 71. Through the connection of the worm gear 73, the grinding roller 74 is driven to perform a rotating movement, realizing the control operation of effectively adjusting the grinding direction of the plastic product.

[0028] During use: When manufacturing and processing plastic products, to improve the smoothness of the surface of plastic products after processing, reduce the accidental injuries to workers caused by burrs on the surface of plastic products, and reduce the processing quality of products, after the burrs on the surface of plastic products are initially removed, the product can be placed on the surface of the device, the electric push rod 2 is turned on to drive the positioning plate 3 to fix the plastic product, and the first servo motor 62 and the second servo motor 66 are turned on to move along a "mouth" - shaped movement trajectory through the adjusting rod 63, driving the grinding roller 74 to reciprocally grind along the periphery of the plastic product, so as to improve the smoothness of the surface grinding of the plastic product 5 after initial deburring.
