[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1-4 As shown, this embodiment provides a technical solution: a plastic pipe bending machine with a straightening function, comprising a base plate 1, a pipe bending assembly 2 is provided on the base plate 1, and a straightening assembly 3 is provided on the base plate 1;

[0033] likeFigures 1-2 As shown, the elbow assembly 2 includes a support frame 21 and a first fixing block 29. The support frame 21 is provided with a first upper pressing plate 27. The first upper pressing plate 27 is provided with a first arc-shaped groove 210. The first fixing block 29 is provided with a second arc-shaped groove 211.

The second upper pressure plate 31 is provided with a first straightening groove 32. A first limit block 35 is provided in the shell 33. The first limit block 35 is slidably connected to the second limit plate 36. The second limit plate 36 is fixedly connected to a push plate 37. The push plate 37 is slidably connected to a moving block 38. The push plate 37 is fixedly connected to a second limit block 39. The second limit block 39 is rotatably connected to a screw rod 310.

In the production process of plastic pipes, straightening is a crucial step, which ensures the straightness and quality of the pipe. The operator starts the first electric telescopic rod 34, and the output end of the telescopic rod pushes the first limit block 35 to move. As the first limit block 35 moves, it drives the second limit plate 36 and the push plate 37 to move upward, thereby lifting the second fixing block 312 to a certain height.

[0035] The above solutions still have the problem that the plastic pipe cannot be cooled after the bending operation. Figures 1-2As shown: the support frame 21 is fixedly connected to the base plate 1, a hydraulic push rod 22 is installed on the support frame 21, the output end of the hydraulic push rod 22 is fixedly connected to the first support plate 23, the first support plate 23 is fixedly connected to the limiting column 24, the limiting column 24 is fixedly connected to the connecting plate 25, the output end of the hydraulic push rod 22 is fixedly connected to the first limiting plate 26, because the support frame 21 is fixedly connected to the base plate 1, so that the base plate 1 can support and fix the support frame 21, because the hydraulic push rod 22 is installed on the support frame 21 , and the output end of the hydraulic push rod 22 is fixedly connected to the first support plate 23, so that when the hydraulic push rod 22 is started, the output end of the hydraulic push rod 22 can drive the first support plate 23 to move. Since the first support plate 23 is fixedly connected to the limiting column 24, the first support plate 23 can support and fix the limiting column 24. Since the limiting column 24 is fixedly connected to the connecting plate 25, the connecting plate 25 can fixedly connect the four limiting columns 24. Since the output end of the hydraulic push rod 22 is fixedly connected to the first limiting column The plate 26 enables the output end of the hydraulic push rod 22 to drive the first limit plate 26 to move when it moves. The first limit plate 26 is slidably connected to the limit column 24. The first upper pressure plate 27 is fixedly connected to the limit column 24.

Since one end of the telescopic spring 28 is fixedly connected to the first limiting plate 26, and the other end of the telescopic spring 28 is fixedly connected to the first upper pressing plate 27, the telescopic spring 28 can exert an elastic force on the first limiting plate 26, thereby playing a buffering role on the first upper pressing plate 27.

[0036] like Figure 1 as well as Figures 3-4As shown, a first electric telescopic rod 34 is installed on the housing 33, a first limit block 35 is fixedly connected to the output end of the first electric telescopic rod 34, a push plate 37 is slidably connected in the housing 33, a second limit block 39 is slidably connected in the housing 33, and a moving block 38 is rotatably connected to the slider 311. Since the first electric telescopic rod 34 is installed on the housing 33 and the first limit block 35 is fixedly connected to the output end of the first electric telescopic rod 34, when the first electric telescopic rod 34 is started, the output end of the first electric telescopic rod 34 can drive the first limit block 35 to move. Since the push plate 37 is slidably connected in the housing 33, when the push plate 37 moves, the housing 33 can limit the movement of the push plate 37. Since the second limit block 39 is slidably connected in the housing 33, when the second limit block 39 moves, the housing 33 can limit the second limit block 39. Since the moving block 38 is rotatably connected to the slider 311, the moving block 38 can adjust the rising degree of the push plate 37.

[0037] like Figure 1 as well as Figure 5 As shown, a cooling assembly 4 is provided on the base plate 1, and the cooling assembly 4 includes a support block 41, which is fixedly connected to the base plate 1, and a second electric telescopic rod 42 is installed on the support block 41, and the output end of the second electric telescopic rod 42 is fixedly connected to the second support plate 43, and a nozzle 44 is provided on the second support plate 43. After the plastic pipe bending operation, the operator starts the second electric telescopic rod 42, and the output end of the second electric telescopic rod 42 pushes the second support plate 43 to move downward, so that the nozzle 44 enters the inside of the bent pipe. A refrigerator 45 is installed on the side of the support block 41 close to the second electric telescopic rod 42, and the output end of the refrigerator 45 is fixedly connected to a hose 46, and the other end of the hose 46 is fixedly connected to the nozzle 44. Subsequently, the refrigerator 45 is started, and the refrigerator 45 passes the cold air through the hose 46 and the nozzle 44 into the bent pipe to cool the bent pipe.

[0038] Working principle:

[0039] like Figures 1-5As shown, in the production process of plastic pipes, straightening is a crucial step, which ensures the straightness and quality of the pipes. The operator starts the first electric telescopic rod 34, and the output end of the telescopic rod pushes the first limit block 35 to move. As the first limit block 35 moves, it drives the second limit plate 36 and the push plate 37 to move upward, thereby lifting the second fixed block 312 to a certain height. At this time, when the first upper pressing plate 27 moves downward, it can drive the second upper pressing plate 31 to move downward together, and straighten the plastic pipe located in the second straightening groove 313. In order to ensure that the heights of the four push plates 37 are consistent, the operator needs to adjust the position of the push plates 37 by cooperating with the moving block 38, the screw rod 310 and the slider 311, so that the operator can accurately control the height of each push plate 37, thereby ensuring the stability and consistency of the plastic pipe during the straightening process. Afterwards, the operator will start the hydraulic push rod 22, and the output end of the hydraulic push rod 22 drives the first support plate 23 and the first limit plate 26 to push downward. When the first upper pressure plate 27 is pushed to contact the first fixed block 29, through the cooperation of the set limit column 24, the first limit plate 26 and the telescopic spring 28, since the limit column 24 is slidably connected in the first limit plate 26, the first upper pressure plate 27 plays a buffering role when pressing down. This buffering role not only protects the equipment from damage, but also improves the quality of the straightening effect. After the plastic pipe bending operation, the operator starts the second electric telescopic rod 42, and the output end of the second electric telescopic rod 42 pushes the second support plate 43 to move downward, so that the nozzle 44 enters the inside of the bent pipe. Then, the refrigerator 45 is started, and the refrigerator 45 sends cold air into the bent pipe through the hose 46 and the nozzle 44 to cool the bent pipe.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
