[0001] This utility model relates to the field of PVC pipe processing technology, specifically to a PVC pipe chamfering processing device. Background Technology

[0002] PVC pipes, or polyvinyl chloride pipes, are plastic pipes made from polyvinyl chloride resin as the main raw material, with the addition of stabilizers, lubricants and other additives, and formed by extrusion.

[0003] Existing PVC pipe chamfering processing equipment can only fix pipes of a fixed diameter due to the different pipe diameters, making it impossible to fix and support pipes of different diameters. In addition, the chamfering cutter wears down over time, which can damage the cutter head. However, the existing equipment cannot quickly replace the cutter. Utility Model Content

[0005] This utility model provides the following technical solution: a PVC pipe chamfering processing device, including a base, a support plate and a support frame fixedly installed on the top of the base, a roller rotatably connected to the inner wall of the support plate, a pressing block slidably connected to the inner wall of the support frame, an extension plate fixedly installed on the outer wall of the pressing block, a cylinder fixedly installed on the top of the extension plate, a pressing seat fixedly installed on the telescopic end of the cylinder, a motor fixedly installed on the top of the support frame, a gear fixedly installed on the output group of the motor, a gear rotatably connected to the inner wall of the support frame, a threaded rod fixedly installed on the top of the pressing block, and a limit rod fixedly installed on the inner wall of the support frame.

A threaded column is rotatably connected to the inner wall of the lower pressure seat. A sliding frame is slidably connected to the inner wall of the lower pressure seat. A fixed block is fixedly installed on the outer wall of the sliding frame. A rotating column is fixedly installed at the end of the threaded column away from the support plate. A push plate is slidably connected to the inner wall of the rotating column. A push plate and a friction plate are fixedly installed on the outer wall of the push plate. A pressure plate is fixedly installed on the outer wall of the push plate. A limit post is fixedly installed on the inner wall of the rotating column. A spring is provided on the inner wall of the rotating column.

[0006] As a preferred technical solution of this utility model: the threaded rod passes through the second gear, and the threaded rod and the second gear are threadedly connected. The first gear is located outside the second gear, and the first gear meshes with the second gear.

[0007] As a preferred technical solution of this utility model: the number of the limiting rods is two, and the two limiting rods are symmetrically arranged, and the two limiting rods pass through both sides of the pressing block.

[0008] As a preferred technical solution of this utility model: the threaded column passes through the sliding frame, and the threaded column and the sliding frame are threadedly connected, and the outer wall of the sliding frame is in contact with the inner wall of the lower pressure seat.

[0009] As a preferred technical solution of this utility model: the shape of the fixing block is adapted to the shape of the inner wall of the fixing plate, and both the outer wall of the fixing block and the inner wall of the fixing plate are inclined.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This PVC pipe chamfering processing device involves placing the pipe above two support rollers, starting motor one, which drives gear one to rotate, and then gear one moves through meshing with gear two. Gear two moves through its threaded connection with a threaded rod, causing the threaded rod to move downwards. The threaded rod then moves the drive wheel downwards, which in turn causes the lower pressure block to move the drive wheel, bringing it into contact with the top of the pipe. At this point, the pipe is fixed to the top of the two support rollers.

[0012] 2. This PVC pipe chamfering processing device, by pressing the pressure plate, causes the pressure plate to move, which in turn causes the push plate and friction plate to move. At this time, the friction plate disengages from the inner wall of the lower pressure seat, and the rotating column can rotate. The rotation of the rotating column causes the threaded column to rotate, which in turn causes the threaded column to move through the threaded connection with the sliding frame, causing the fixed block of the sliding frame to move, thus separating the fixed block from the inner wall of the fixed plate. At this time, the fixing relationship of the fixed plate disappears, and it can then be replaced. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1 - Figure 5 A PVC pipe chamfering processing device includes a base 1. A support plate 2 and a support frame 3 are fixedly installed on the top of the base 1. A roller 4 is rotatably connected to the inner wall of the support plate 2. A lower pressure block 5 is slidably connected to the inner wall of the support frame 3. An extension plate 6 is fixedly installed on the outer wall of the lower pressure block 5. A cylinder 7 is fixedly installed on the top of the extension plate 6. A lower pressure seat 8 is fixedly installed at the telescopic end of the cylinder 7. A motor 9 is fixedly installed on the top of the support frame 3. A gear 10 is fixedly installed on the output assembly of the motor 9. A gear 11 is rotatably connected to the inner wall of the support frame 3. A threaded rod 12 is fixedly installed on the top of the lower pressure block 5. A limit rod 13 is fixedly installed on the inner wall of the support frame 3. A motor 14 is fixedly installed on the bottom outer wall of the lower pressure block 5. The output shaft of motor 214 is fixedly mounted with a drive wheel 15. A fixed plate 16 is slidably connected to the inner wall of the lower pressure seat 8. A cutting blade 17 is fixedly mounted at the bottom of the fixed plate 16. A threaded column 18 is rotatably connected to the inner wall of the lower pressure seat 8. A sliding frame 19 is slidably connected to the inner wall of the lower pressure seat 8. A fixed block 20 is fixedly mounted on the outer wall of the sliding frame 19. A rotating column 21 is fixedly mounted at the end of the threaded column 18 away from the support plate 2. A push plate 22 is slidably connected to the inner wall of the rotating column 21. A push plate 23 and a friction plate 24 are fixedly mounted on the outer wall of the push plate 22. A pressure plate 25 is fixedly mounted on the outer wall of the push plate 23. A limit column 26 is fixedly mounted on the inner wall of the rotating column 21. A spring 27 is provided on the inner wall of the rotating column 21.

[0017] In the above structure, the symmetrical arrangement of the two support plates 2 and the rollers 4, and the oblique placement of the two support plates 2 and the rollers 4, allows the pipe to be placed on top of the two rollers 4, so that the two rollers 4 support the bottom of the pipe.

[0018] In a preferred embodiment: the threaded rod 12 passes through the gear 2 11, and the threaded rod 12 and the gear 2 11 are threadedly connected. The gear 10 is located outside the gear 2 11, and the gear 10 meshes with the gear 2 11.

[0019] In the above structure, by starting motor 9, motor 9 drives gear 10 to rotate, which in turn causes gear 10 to rotate through meshing with gear 2 11. Gear 2 11 then moves through its threaded connection with threaded rod 12, which in turn causes the bottom pressure block 5 to move.

[0020] In a preferred embodiment, there are two limiting rods 13, and the two limiting rods 13 are symmetrically arranged, with the two limiting rods 13 passing through both sides of the pressing block 5.

[0021] In the above structure, the two limiting rods 13 pass through both sides of the pressing block 5, so that when the pressing block 5 moves, the two sides of the pressing block 5 can only slide on the outer wall of the two limiting rods 13, so that the two limiting rods 13 limit the pressing block 5, thereby preventing the pressing block 5 from shifting position when it moves.

[0022] In a preferred embodiment, the threaded post 18 passes through the sliding frame 19, and the threaded post 18 and the sliding frame 19 are threadedly connected, with the outer wall of the sliding frame 19 fitting against the inner wall of the lower pressure seat 8.

[0023] In the above structure, by rotating the rotating column 21, the rotating column 21 causes the threaded column 18 to rotate, which in turn causes the threaded column 18 to move through the threaded connection with the sliding frame 19, causing the fixed block 20 of the sliding frame 19 to move.

[0024] In a preferred embodiment, the shape of the fixing block 20 is adapted to the shape of the inner wall of the fixing plate 16, and both the outer wall of the fixing block 20 and the inner wall of the fixing plate 16 are inclined.

[0025] In the above structure, the fixed block 20 moves towards the fixed plate 16, causing the inclined surface of the outer wall of the fixed block 20 to fit against the inclined surface of the inner wall of the fixed plate 16. This causes the inclined surface of the outer wall of the fixed block 20 to press against the inclined surface of the inner wall of the fixed plate 16, causing the fixed plate 16 to move until the fixed block 20 and the inner wall of the fixed plate 16 are completely fitted together, thus fixing the position of the fixed plate 16.

[0026] In a preferred embodiment, the outer wall curvature of the friction plate 24 is adapted to the inner wall of the lower pressure seat 8, and the friction plate 24 is in contact with the inner wall of the lower pressure seat 8.

[0027] In the above structure, the spring 27 pushes the push plate 22 outward, which in turn causes the push plate 22 to drive the friction plate 24 to move outward, so that the friction plate 24 fits against the inner wall of the lower pressure seat 8. At this time, the friction between the friction plate 24 and the lower pressure seat 8 increases, so that the friction plate 24 cannot rotate, and thus the rotating column 21 cannot rotate.

[0028] Working principle: When using the equipment, the pipe is placed on top of the two support rollers 4, which lift the bottom of the pipe. Motor 9 is then started, driving gear 10 to rotate. Gear 10 meshes with gear 11, causing gear 11 to rotate. Gear 11 moves through its threaded connection with threaded rod 12, moving the bottom pressure block 5. The pressure block 5 then moves the bottom motor 14 and drive wheel 15 downwards, bringing the drive wheel 15 into contact with the top of the pipe, thus fixing the pipe to the top of the two support rollers 4. Cylinder 7 is then started, moving the pressure seat 8 downwards. This causes the pressure seat 8 to move the fixing plate 16 and cutting blade 17 downwards. Motor 14 is then started... The drive wheel 15 rotates, which in turn drives the pipe to rotate. The rotation of the pipe causes the cutting blade 17 to chamfer and cut the pipe. When the cutting blade 17 needs to be replaced, pressing the pressure plate 25 causes the pressure plate 25 to drive the push plate 23 to move. The push plate 23 then drives the push plate 22 and the friction plate 24 to move. At this time, the friction plate 24 disengages from the inner wall of the lower pressure seat 8, and the rotating column 21 can rotate. The rotation of the rotating column 21 causes the threaded column 18 to rotate, which in turn causes the threaded column 18 to drive the sliding frame 19 to move through the threaded connection with the sliding frame 19. This causes the fixed block 20 of the sliding frame 19 to move, separating the fixed block 20 from the inner wall of the fixed plate 16. At this time, the fixing relationship of the fixed plate 16 disappears, and it can then be replaced. After replacement, the structure can be reset.
