[0002] Plastic shell processing is a complex process involving multiple steps, mainly including the following aspects: material selection, mold design and manufacturing, forming process, surface treatment, quality control, application fields, etc. Deburring is an important link in the surface treatment process of plastic shell processing, which is related to the appearance quality, dimensional accuracy and service performance of the product.
[0003] Most of the existing burr removal devices are used to remove burrs on the plastic surface. However, in order to maintain the docking stability between plastic components, some plastic shells also need to remove burrs on their inner walls. Among them, circular plastic shells are widely used, but there are few existing burr removal devices for the inner walls of plastic tubes. If manual grinding is used to remove burrs, the efficiency is relatively low. Therefore, a burr trimming device for plastic shell processing is proposed to solve the above problems.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0027] In the embodiment, by Figures 1-4Provided is a burr trimming device for plastic shell processing. The utility model includes a base 1. A moving device 2 is arranged inside the base 1. A mounting plate 3 is fixedly connected to the outside of the moving device 2. A support plate 4 is arranged on the top of the mounting plate 3. A second motor 5 is fixedly connected to the outside of the support plate 4. An extension rod 6 is fixedly connected to the outside of the output shaft of the second motor 5. A grinding head 7 is fixedly connected to the right side of the extension rod 6. A support frame 8 is fixedly connected to the top of the base 1. A first electric push rod 9 is fixedly connected to the inside of the support frame 8. A fixing frame 10 is fixedly connected to the bottom of the first electric push rod 9. Two rollers 11 which are symmetrically distributed front and back are rotatably connected to the inside of the fixing frame 10. A third motor 12 is fixedly connected to the top of the base 1. A first rotating roller 13 which is rotatably connected to the top of the base 1 is fixedly connected to the outside of the output shaft of the third motor 12. A second rotating roller 14 which is rotatably connected to the top of the base 1 is arranged on the front side of the first rotating roller 13.
[0028] Among them, the moving device 2 includes a first motor 21 fixedly connected to the outside of the base 1. A threaded rod 22 which is rotatably connected to the inside of the base 1 is fixedly connected to the outside of the output shaft of the first motor 21. A transmission block 23 fixedly connected to the bottom of the mounting plate 3 is in threaded transmission connection with the outside of the threaded rod 22.
[0029] In this embodiment, during the actual use process, the start of the first motor 21 will drive the threaded rod 22 to rotate, and under the action of the thread, the transmission block 23 drives the mounting plate 3 to move.
[0030] Among them, a sliding rod 15 is fixedly connected to the inside of the base 1. A sliding sleeve 16 which is slidably connected to the sliding rod 15 is fixedly connected to the bottom of the mounting plate 3.
[0031] In this embodiment, during the actual use process, when the mounting plate 3 moves, the sliding sleeve 16 will simultaneously slide on the outside of the sliding rod 15 and provide support for the mounting plate 3.
[0032] Among them, the fixing frame 10 is arranged in a Y shape, and buffer pads 17 are arranged on the outside of both rollers 11.
[0033] In this embodiment, during the actual use process, the Y-shaped fixing frame 10 applies pressure to the plastic round tube in two directions by the rollers 11, and the buffer pads 17 make the plastic round tube fit more stably with the rollers 11.
[0034] Among them, the symmetry center plane of the first rotating roller 13 and the second rotating roller 14 is on the same horizontal plane as the center line of the grinding head 7.
[0035] In this embodiment, during actual use, when the size of the plastic round tube changes, the axial axes of the grinding head 7 and the two rotating rollers are still in the same plane, and the central axis of the plastic round tube is also in the same plane as the grinding head 7.
[0036] Among them, a fixed frame 18 slidably connected to the support plate 4 is fixedly connected to the top of the mounting plate 3, and a second electric push rod 19 fixedly connected to the bottom of the support plate 4 is fixedly connected to the top of the mounting plate 3.
[0037] In this embodiment, during actual use, when the size of the plastic round tube changes, by starting the second electric push rod 19, the support plate 4 can be moved up and down, thereby changing the height of the grinding head 7. Then, by changing the size of the grinding head 7, the inside of the plastic round tube can be polished to remove burrs.
[0038] Working principle:
[0039] First, place the plastic pipe fitting that needs to have its burrs removed between the two rotating rollers. Then start the first electric push rod 9 to lower the fixing frame 10, so that the two rollers 11 press and fix the plastic pipe fitting. Then start the third motor 12, and the third motor 12 will drive the rear first rotating roller 13 to rotate. Under the pressing and fixing of the rollers 11, the second rotating roller 14 will also rotate, and the plastic pipe fitting will also rotate through the rotation of the rollers 11. Then start the first motor 21 to move the mounting plate 3, and at the same time drive the grinding head 7 to rotate through the second motor 5, and the rotation direction is opposite to the rotation direction of the plastic round tube to make the grinding faster. As the mounting plate 3 slowly moves, the grinding position of the plastic round tube will slowly change.
