Description

Technical Field

[0001] This utility model relates to the field of polishing technology for plastic products, and specifically discloses a device for polishing the surface of plastic products. Background Technology

[0002] During the production of plastic products, due to limitations in molding processes such as injection molding and extrusion, the surfaces often have defects such as burrs, flash, or unevenness, affecting the appearance quality and performance of the products. Therefore, surface polishing is an important post-processing step for plastic products.

[0003] Most existing polishing equipment is designed for flat or regular-shaped plastic products, and it is difficult to adapt to the polishing needs of curved surfaces of conical or tubular plastic products. For the polishing of curved surfaces of conical or tubular plastic products, manual polishing is usually required, which is inconvenient. Therefore, a plastic product surface polishing device is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a surface polishing device for plastic products. Through an automatic polishing mechanism, it can automatically polish and grind conical or tubular plastic products of different sizes, which is convenient to use.

[0005] This utility model is implemented as follows: a surface polishing device for plastic products includes a support frame, an automatic polishing mechanism inside the support frame, and a U-shaped frame fixedly connected to the upper end of the support frame. A lead screw is rotatably connected inside the U-shaped frame, and a drive plate is threadedly connected to the outer wall of the lead screw. A pressure sensor is connected to the right end of the drive plate, and a mounting base is fixedly connected to the right end of the pressure sensor. A mounting plate is fixedly connected to the right end of the mounting base. A first motor is mounted at the front end of the mounting plate, and a polishing roller is fixedly connected to the output end of the first motor through the mounting plate. An electric push rod is mounted at the upper end of the support frame, and a frame is fixedly connected to the output end of the electric push rod through the support frame. A second motor is mounted inside the frame, and a clamping assembly is fixedly connected to the output end of the second motor through the frame.

[0006] As a preferred embodiment of the plastic product surface polishing device of this utility model, the clamping assembly includes an auxiliary frame fixedly connected to the output end of a second motor, a bidirectional lead screw rotatably connected inside the auxiliary frame, two symmetrically distributed clamping plates threaded to the outer wall of the bidirectional lead screw, and a third motor whose output end is fixedly connected to the bidirectional lead screw is installed on the outer wall of the auxiliary frame.

[0007] As a preferred embodiment of the plastic product surface polishing device of this utility model, the outer wall of the U-shaped frame is equipped with a fourth motor whose output end is fixedly connected to the lead screw.

[0008] As a preferred embodiment of the plastic product surface polishing device of this utility model, an arc-shaped anti-slip pad is fixedly connected to the opposite sides of the two clamping plates.

[0009] As a preferred embodiment of the plastic product surface polishing device of this utility model, the U-shaped frame has a sliding groove inside, the lower end of the drive plate is slidably connected to the sliding groove through a slider, and the upper ends of the two clamping plates are slidably connected to the inner wall of the auxiliary frame.

[0010] As a preferred embodiment of the plastic product surface polishing device of this utility model, the inner wall of the support frame is provided with a slide rail, and the right end of the frame is slidably connected to the slide rail through a limiting block.

[0011] As a preferred embodiment of the plastic product surface polishing device of this utility model, a controller is installed at the right end of the support frame.

[0012] The beneficial effects of this utility model are:

[0013] 1. Automated polishing improves efficiency.

[0014] The longitudinal position of the plastic product is automatically adjusted by an electric actuator, and the clamping assembly is rotated by a second motor. The pressure sensor monitors the polishing pressure in real time, and the lateral position of the polishing roller is adjusted by a fourth motor driving the lead screw. This ensures that the polishing roller always fits the surface contour of the plastic product, achieving continuous and uniform polishing, reducing manual intervention, and improving production efficiency. It is especially suitable for polishing tapered plastic tubes.

[0015] 2. Uniform polishing improves surface quality.

[0016] While the polishing roller rotates at high speed, the plastic product slowly rotates under the drive of the second motor. Combined with the longitudinal feed of the electric push rod, this ensures that the polishing covers the entire curved surface, avoids local over-polishing or missed polishing, and improves the uniformity of polishing.
