Description

Technical Field

[0001] The utility model relates to the technical field of pipes, in particular to a plastic pipe bending device. Background Art

[0002] Plastic pipes are generally made of synthetic resin, that is, polyester, with stabilizers, lubricants, plasticizers, etc. added, and are extruded in a pipe making machine by the "plastic" method. They are mainly used as pipes for tap water supply systems in buildings, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation. As an important part of chemical building materials, plastic pipes are widely accepted by users for their superior performance, hygiene, environmental protection and low consumption. In the production process of plastic pipes, plastic pipes need to be bent. The plastic pipe bending devices currently available on the market still have some disadvantages;

[0003] The existing plastic pipe bending device can only bend a single pipe at a time, which will lead to low pipe bending production efficiency. At the same time, manual operation is required when bending the pipe, which consumes a lot of manpower, and also leads to low production efficiency. For example, the Chinese utility model patent with authorization announcement number CN220594036U discloses a plastic pipe bending device, including a back plate and a pipe body, the left front outer wall of the back plate is connected to the pipe body through a limit mechanism, and the right top of the pipe body abuts against the outer wall of the left bottom end of the rotating wheel, the middle of the rotating wheel is installed in the middle of the rotating rod through a connecting shaft, and the top of the rotating rod is connected to the outer wall of the front side of the back plate through a fixed shaft. The utility model can adjust the bending angle of the pipe body under the action of adjusting the offset angle of the rotating rod, and the bending efficiency is improved through the coordinated rotation of the connecting shaft and the fixed shaft and the self-rotation efficiency of the connecting shaft. However, this device can only bend a single pipe at a time, which will lead to low production efficiency of pipe bending. At the same time, manual operation is required to be performed when bending the pipe, which consumes a lot of manpower and also leads to problems such as low production efficiency. Therefore, we propose a plastic pipe bending device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of 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.

[0028] Please refer to Figure 1-6 , the present utility model provides a technical solution: a plastic pipe bending device, comprising: a conveyor belt 1, a clamping bottom plate 2, a placement groove 3, a pipe body 4, a card slot 5, a clamping top plate 6, a clamping block 7, a sliding block 8, a sliding groove 9, a support plate 10, an electric telescopic rod 11, a fixing frame 12, a bending wheel 13, a rotating shaft 14, a fixing block 15, a threaded rod 16, a fixing rod 17, a limiting rod 18, a motor 19 and a bending block 20;

[0029] As shown in Figure 1 , Figure 4 and Figure 6As shown in the figure, clamping bottom plates 2 are equidistantly arranged above the conveyor belt 1. When the conveyor belt 1 is turned on, the conveyor belt 1 starts to run. At the same time, a placement groove 3 is opened inside the clamping bottom plate 2. When the conveyor belt 1 starts to run, the clamping bottom plate 2 moves, and the pipe body 4 can be placed into the placement groove 3 inside the clamping bottom plate 2. After all the placement grooves 3 inside the clamping bottom plate 2 are filled, the conveyor belt 1 is turned off to stop its operation;

[0030] As Figure 1 、 Figure 2 and Figure 5 As shown in the figure, after the pipe body 4 is placed, a clamping groove 5 is opened above the inside of the clamping bottom plate 2. At the same time, a clamping top plate 6 is arranged above the clamping bottom plate 2. Placement grooves 3 are also equidistantly arranged inside the clamping top plate 6. The placement grooves 3 inside the clamping top plate 6 and the placement grooves 3 inside the clamping bottom plate 2 correspond to each other one by one up and down. In addition, a clamping block 7 is installed below the clamping top plate 6. Secondly, an electric telescopic rod 11 is installed above the middle of the clamping top plate 6. The electric telescopic rod 11 is fixedly connected to the support plate 10. The sliding blocks 8 are symmetrically and fixedly installed on the left and right sides at the rear of the clamping top plate 6. The sliding blocks 8 are slidably arranged inside the sliding grooves 9. The sliding grooves 9 are symmetrically opened on the left and right sides inside the support plate 10. That is, when the electric telescopic rod 11 is turned on, the output end of the electric telescopic rod 11 can push the clamping top plate 6 to move downward. At this time, the sliding blocks 8 will slide inside the sliding grooves 9, enabling the clamping top plate 6 to move downward smoothly. Finally, the clamping top plate 6 moves downward until the clamping block 7 below is engaged with the clamping groove 5 inside the clamping bottom plate 2, that is, the pipe body 4 can be firmly clamped inside the placement groove 3, ensuring that the pipe body 4 will not move during bending, which will greatly improve the bending accuracy of the pipe body 4;

[0031] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, after the pipe body 4 is firmly clamped, it is necessary to bend the front side of the pipe body 4. A bending block 20 is arranged below the front side of the pipe body 4. The bending block 20 is fixedly connected to the conveyor belt 1. A bending wheel 13 is arranged above the front side of the pipe body 4. A rotating shaft 14 is rotatably installed inside the bending wheel 13. At the same time, fixing blocks 15 are symmetrically installed on the left and right sides of the bending wheel 13. A threaded rod 16 is installed inside the left side of the fixing block 15 in a threaded manner, and a limiting rod 18 is slidably installed inside the right side of the fixing block 15. In addition, the threaded rod 16 and the limiting rod 18 are arranged inside the fixing frame 12. By turning on the motor 19, the threaded rod 16 will rotate. When the threaded rod 16 rotates, since a fixing rod 17 is engaged and installed inside the rear side of the fixing block 15 on the outer side of the threaded rod 16, the fixing block 15 can drive the bending wheel 13 to move downward. The bending wheel 13 can squeeze and roll the pipe body 4, causing the pipe body 4 to bend. Without the need for manual labor, the bending operation of the pipe body 4 can be carried out, greatly saving manpower.
