[0002] PVC is a white powder with an amorphous structure. It has poor stability to light and heat, no fixed melting point, good mechanical properties, and excellent dielectric properties. It is widely used in building materials, industrial products, daily necessities, floor coverings, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers.
[0003] Some PVC pipes require chamfering at the ends to suit specific applications. However, current chamfering equipment cannot precisely control the chamfer angle and cannot be applied gradually during the chamfering process, which can easily result in an excessively large chamfer at once, causing damage to the pipe.

[0013] (III) Beneficial Effects
[0014] This utility model provides a PVC pipe beveling device. It has the following beneficial effects:
[0015] 1. This PVC pipe chamfering equipment, by setting up a threaded column, a spacer rod, a support sleeve, and a threaded block, brings the support sleeve into contact with the end face of the pipe. The motor is started, driving the threaded column and the threaded block to gradually move downwards. At the same time, the threaded column, spring A, and the cylinder drive the grinding plate to move downwards and rotate, gradually chamfering the end face of the pipe. When the support sleeve contacts the lower end of the spacer rod, the movable ring no longer moves relative to the cylinder, limiting the grinding depth and angle of the grinding plate. This solves the problem of not being able to accurately control the chamfering angle and the inability to gradually chamfer, which can easily cause excessive chamfering in one go and damage the pipe.
[0016] 2. This PVC pipe chamfering device, by setting a threaded rod and an inner rod, rotates the threaded rod to engage with the inner rod, causing the support sleeve to slide on the inner rod, changing the distance between the support sleeve and the cylinder, thus adapting to pipes within a certain diameter range.

Detailed Implementation
[0022] 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.
[0023] This utility model embodiment provides a PVC pipe beveling device, such as... Figure 1-4As shown, the device includes a fixed plate 1 and a handle 2. The lower end of the handle 2 is fixedly connected to the upper surface of the fixed plate 1. A motor 3 is installed above the fixed plate 1. Short plates 4 are fixedly connected to the left and right sides of the motor 3. Upright rods 5 slide through the upper surfaces of both short plates 4. The lower ends of both upright rods 5 are fixedly connected to the upper surface of the fixed plate 1. Threaded blocks 7 are fixedly inserted through the upper surface of the fixed plate 1. Threaded posts 6 are threaded through the upper surface of the threaded blocks 7. The two upright rods 5 are arranged in parallel and are symmetrically distributed about the axis of the motor 3. When the motor 3 rotates, it drives... When the threaded column 6 and the threaded block 7 move up and down in engagement, the short plate 4 slides on the upright 5 to ensure the stability of the motor 3 during movement. The upper end of the threaded column 6 is fixedly connected to the output end of the motor 3. A cylinder 10 is provided below the threaded column 6, and a rib 8 is fixedly connected to the upper end of the cylinder 10. The lower end of the threaded column 6 is slidably sleeved on the upper end of the rib 8. When the threaded column 6 rotates, it can drive the cylinder 10 to move synchronously through the rib 8. A spring A9 is provided inside the threaded column 6. When the threaded column 6 moves downward, it can push the rib 8 and the cylinder 10 synchronously downward through the spring A9. The cylinder moves downwards, with the lower end of spring A9 fixedly connected to the upper end of the rib 8, and the upper end of spring A9 fixedly connected to the inner top wall of the threaded column 6. A grinding plate 11 is hinged to the lower end of the cylinder 10, and a movable ring 12 is slidably fitted onto the outer surface of the cylinder 10. The movable ring 12 is located above the grinding plate 11. Grooves 22 are provided on both the front and rear sides of the cylinder 10, and the inner ring surface of the movable ring 12 is slidably inserted into the two grooves 22 to ensure that the movable ring 12 rotates synchronously with the cylinder 10. A spring B13 is fixedly connected to the upper surface of the movable ring 12, and the spring B13 has low elasticity. Due to the elasticity of spring A9, spring B13 is compressed first when subjected to pressure. A fixed ring 14 is fixedly connected to the upper end of spring B13. The fixed ring 14 is fixedly sleeved on the outer surface of cylinder 10. Spring B13 is movably sleeved on the outer surface of cylinder 10. A telescopic rod 15 is fixedly connected to the right side of the movable ring 12. A hinge rod 18 is fixedly connected to the bottom surface of the other end of the telescopic rod 15. The lower end of the hinge rod 18 is hinged to the right end of the grinding plate 11. The telescopic rod 15 is set horizontally. The telescopic rod 15 and the hinge rod 18 are set perpendicularly. The telescopic rod 15 is set perpendicularly to cylinder 10.
[0024] The front and rear sides of the movable ring 12 are fixedly connected with inner rods 17. The ends of the two inner rods 17 that are far apart from each other are slidably sleeved with support sleeves 19. The sides of the two inner rods 17 that are far apart from each other are threaded with threaded rods 16. The two support sleeves 19 are respectively movably sleeved on the outer surfaces of the two threaded rods 16. The bottom surface of the support sleeves 19 is rolled with balls 21. The two support sleeves 19 are coaxially arranged. The balls 21 reduce the wear between the support sleeves 19 and the end face of the pipe and improve the smoothness. The upper part of the two support sleeves 19 is provided with a spacer rod 20. The upper end of the two spacer rods 20 is threaded through the upper surface of the fixed ring 14. The two spacer rods 20 are arranged in parallel and are symmetrically distributed about the axis of the cylinder 10. By rotating the spacer rod 20 to engage with the fixed ring 14, the distance between the lower end of the spacer rod 20 and the support sleeve 19 can be changed.
[0025] Working principle: During chamfering, the support sleeve 19 contacts the end face of the pipe. The motor 3 is started, which drives the threaded column 6 to engage with the threaded block 7 and gradually move downwards, causing the upright 5 to slide within the short plate 4. Simultaneously, the grinding plate 11 is moved downwards and rotated by the threaded column 6, spring A9, and cylinder 10, causing the movable ring 12 to slide on the surface of cylinder 10. Spring B13 is compressed, and the end face of the pipe is gradually chamfered. When the support sleeve 19 contacts the lower end of the spacer rod 20, the movable ring 12 no longer moves relative to cylinder 10. When the spacer rod 20 is rotated, the initial distance between the lower end of the spacer rod 20 and the support sleeve 19 is changed, thus allowing for different angle treatments. After the spacer rod 20 contacts the support sleeve 19, as the threaded column 6 continues to move downwards, the rib 8 slides within the threaded column 6, compressing spring A9.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
