[0081] The second motor 46 drives the second bevel gear 42 to rotate, thereby driving the meshing transmission of the first bevel gear 41 and the second bevel gear 42, causing the threaded column to rotate, thus driving the bending mechanism to work. This design makes the movement of the square frame 29 more precise and stable, thereby improving the accuracy and efficiency of PVC pipe bending.

[0082] A double-headed toothed tube 47 is driven between the first toothed tube 43 and the second toothed tube 44; one end of the double-headed toothed tube 47 is slidably engaged with the first toothed tube 43, and the other end is slidably engaged with the second toothed tube 44; one end of the transmission column 40 is fixedly connected to a limiting tube 48, and a limiting device 49 is slidably connected to the surface of the limiting tube 48, and one end of the limiting device 49 is fixedly connected to the main base 1.

[0083] When the connecting column 32 moves to the desired position, it can push the double-headed toothed tube 47 on the surface of the connecting column 32 to mesh with the first toothed tube 43, thereby driving the rotation of the transmission column 40 and the threaded rod to achieve batch bending operations.

[0084] The second fixing frame 36 has several first limiting sleeves 50 on one side, which are sleeved on the outside of the sliding column 34; the fourth fixing frame 38 has several second limiting sleeves 51 on one side, which are sleeved on the outside of the sliding column 34; the first limiting sleeves 50 are fixedly connected to a second spring 52; the second limiting sleeves 51 are fixedly connected to a third spring 53; the second fixing frame 36 is fixedly connected to a push handle 54, and the push handle 54 is slidably connected to a bending correction plate 55.

[0085] Pushing the push handle 54 restricts the movement distance of the square frame 29. At the same time, it stops when the connecting column 32 reaches the limiting sleeve at one end. The threaded rod 33 moves and drives the double-headed toothed tube 47 to mesh with another first toothed tube. The third bevel gear 45 drives the threaded rod 33 to rotate in the opposite direction. This cycle can be repeated to perform large-scale bending operations, which greatly improves production efficiency.

[0086] A feed inlet 56 is provided on one side of the storage structure 3, and a pusher groove 57 is provided on one side of the storage structure 3. The pusher groove 57 is flush with the first spring 15. Several fixed toothed plates 58 are fixedly connected to the middle of the storage structure 3. Movable toothed plates 59 are installed between the several fixed toothed plates 58. The movable toothed plates 59 are staggered with the fixed toothed plates 58. Several limiting posts 60 are fixedly connected to the corners of the movable toothed plates 59. The limiting posts 60 are slidably connected to the main base 1.

[0087] Workers only need to put the PVC pipes into the storage structure 3, and the transmission structure 4 can automatically feed them. The degree of automation is high and the labor cost is reduced.

[0088] A protrusion 61 is fixedly connected to the middle of the bottom end of the movable toothed plate 59. A push block 62 is slidably connected to the bottom end of the protrusion 61. A hydraulic push rod 63 is fixedly connected to one side of the push block 62. The telescopic end of the hydraulic push rod 63 is fixedly connected to the push block 62. A limit block 64 is fixedly connected to the bottom end of the push block 62. A sliding groove 65 is provided on the outer side of the limit block 64. The limit block 64 and the sliding groove 65 are slidably connected. The sliding groove 65 is fixedly connected to the main base 1.

[0089] The main base is equipped with a discharge slide 66, which greatly improves the automation level and production efficiency of PVC pipe bending operations.

[0090] The PVC pipe enters the groove between the fixed toothed plates 58 through the feed port 56. At this time, the hydraulic push rod pushes the push block to move. The push block lifts the movable toothed plate 59 through the protrusion 61, realizing the automatic movement of the PVC pipe and performing individual feeding operation. The steps are clear and the bending effect is accurate and reliable.

[0091] The working principle of this embodiment is as follows: The operator simply places the PVC pipe into the storage structure 3. The PVC pipe enters the groove between the fixed toothed plates 58 through the feed port 56. At this time, the hydraulic push rod 63 pushes the push block 62 to move. The push block 62, through the protrusion 61, lifts the movable toothed plate 59, realizing the automatic movement of the PVC pipe for individual feeding. Driven by the first motor 23, the transmission plate 22 drives the pull plate 21 to rotate. The pull plate 21 then drives the slide plate 19 to slide within the sliding cavity 18. The push rod 24 pushes the PVC pipe in the transmission structure 4 between the central column 10 and the two bending columns 13. At this time, pulling the push handle 54 limits the movement distance of the square frame 29, controlling the meshing degree of the upper and lower racks 30 and the upper gear 26 and the lower gear 25, thereby controlling the bending angle of the PVC pipe. The drive of the second motor 46... The third bevel gear 45 rotates, thereby driving the meshing transmission of the first bevel gear 41 and the second bevel gear 42, causing the threaded rod 33 to rotate and pushing the connecting rod 32 to move, thus driving the bending mechanism to work. When the connecting rod 32 reaches the limit sleeve at one end, it stops. The threaded rod 33 moves and drives the double-headed toothed tube 47 to mesh with another first toothed tube 43. The structure of the third bevel gear 45 drives the threaded rod 33 to rotate in the opposite direction. This cycle can be repeated to perform large-volume bending operations, greatly improving production efficiency. After bending, the slide plate 19, through the cooperation of the inclined groove 20 and the L-shaped groove 17, causes the center rod 10 to move along the L-shaped groove 17. During this process, the center rod 10 pushes the PVC pipe to fall off the first spring 15 and slide out through the discharge slide 66, completing the operation. This design greatly improves the automation level and production efficiency of PVC pipe bending operations.
