[0034] Front-back moving device 400 is used to drive the PVC pipe clamped by clamping device 200 to move along front-back direction.

[0035] The support device 100 is used to support the PVC pipe for subsequent operations. The first connecting member 205 and the second connecting member 206 can move away from and close to each other to clamp the PVC pipe. The rotating device 202 is connected with the first connecting member 205, and is used to drive the clamped PVC pipe to rotate. This design allows the PVC pipe to be kept stable during the hole opening process, and the pipe can be rotated as needed to open holes at different positions. The hole opening device 300 is responsible for the hole opening operation of the PVC pipe. It includes a first left-right moving device 310 and a hole opening component 320. The first left-right moving device 310 is connected with the hole opening component 320, and is used to drive the hole opening component 320 to move in the left-right direction to open holes on the PVC pipe. This moving mechanism can accurately control the position of the hole opening. The support device 100, the clamping device 200 and the rotating device 202 are arranged on the front-back moving device 400. The front-back moving device 400 is used to drive the clamped PVC pipe to move in the front-back direction. This moving ability allows the machine to open holes at different positions of the PVC pipe.

[0036] The working principle of the utility model is as follows:

[0037] Firstly, the PVC pipe is placed on the support device 100. Then, the clamping device 200 clamps the PVC pipe. The first connecting member 205 and the second connecting member 206 can move away from and close to each other to adapt to PVC pipes of different diameters, and to ensure that the pipe does not move during processing. The first connecting member 205 is connected with the rotating device 202, and the rotating device 202 drives the clamped PVC pipe to rotate. The front-back moving device 400 drives the clamped PVC pipe to move in the front-back direction. The hole opening component 320 of the hole opening device 300 moves in the left-right direction under the drive of the first left-right moving device 310 to perform the hole opening operation. Through the cooperation of the rotating device 202, the front-back moving device 400 and the first left-right moving device 310, the hole opening component 320 can open holes at different positions of the PVC pipe. The PVC pipe automatic hole opening machine of the utility model greatly improves the efficiency and precision of the hole opening work through the cooperative work of various devices.

[0038] In some embodiments, the second left-right moving device 201 includes a fixed seat 203 and a moving assembly 204 capable of moving away from and close to the fixed seat 203, the first connecting member 205 is rotatably connected with the fixed seat 203, the second connecting member 206 is rotatably connected with the moving assembly 204, the rotating device 202 includes a first driving device 207 for driving the first connecting member 205 to rotate, the first driving device 207 is fixed on the fixed seat 203, and the first connecting member 205 is connected with the first driving device 207.

[0039] The fixed base 203 provides a foundation for mounting and supporting other components. The moving assembly 204 is capable of moving away from or approaching the fixed base 203 in order to adjust the clamping position to accommodate PVC pipes of different diameters. The first connecting piece 205 and the second connecting piece 206 are used to abut the two ends of the PVC pipe, ensuring that the pipe remains stable during rotation. The first driving device 207 is fixed on the fixed base 203 and connected to the first connecting piece 205, used to drive the first connecting piece 205. The first driving device 207 can be a motor or other type of driver, responsible for providing rotational power. The second connecting piece 206 is rotationally connected to the moving assembly 204, which means that the second connecting piece 206 can move under the drive of the moving assembly 204 while maintaining contact with the end of the PVC pipe to achieve the rotation of the pipe. This design allows the second left-right moving device 201 and the rotating device 202 to work together to ensure that the PVC pipe is firmly clamped and can rotate smoothly during the hole opening process. By adjusting the moving assembly 204, different sizes of PVC pipes can be accommodated, increasing the flexibility and applicability of the machine. The fixed and connected manner of the first driving device 207 ensures the stability and reliability of the rotating action.

[0040] Further, the moving assembly 204 includes a second sliding rail 208, a second sliding block 209, and a second driving device 210, the second sliding rail 208 is in sliding cooperation with the second sliding block 209, and the second driving device 210 is connected to the second sliding block 209 and used to drive the second sliding block 209 to slide along the second sliding rail 208, and the second connecting piece 206 is rotationally connected to the second sliding block 209.

[0041] The second sliding rail 208 is a guide component of the moving assembly 204, used to guide the moving direction of the second sliding block 209. The second driving device 210 is connected to the second sliding block 209 and used to drive the second sliding block 209 to slide along the second sliding rail 208. The second driving device 210 can be a motor, a pneumatic cylinder or other type of driver, responsible for providing the power for the movement of the sliding block. The rotational connection between the second connecting piece 206 and the second sliding block 209 allows the second connecting piece 206 to maintain contact with the end of the PVC pipe when the sliding block moves, to achieve the rotation of the pipe. This rotational connection can be achieved through bearings or other rotating mechanisms to ensure the smoothness and accuracy of rotation.

[0042] Further, the first connecting piece 205 and the second connecting piece 206 are conical in shape, and the outer diameter of the first connecting piece 205 and the second connecting piece 206 gradually decreases in the direction of approaching each other.

[0043] The conical design of the connecting pieces provides better contact area and pressure distribution when abutting against the two ends of the PVC pipe, allowing for a more stable clamping of the pipe. The gradual reduction in the outer diameter of the first connecting piece 205 and the second connecting piece 206 means that their pointed or smaller diameter ends are facing each other. The pointed or smaller diameter ends facing each other can provide greater contact pressure when clamping, thereby enhancing the clamping force on the PVC pipe. The contact points can be automatically adjusted when clamping to accommodate changes in the diameter of the pipe.

[0044] In some embodiments, the support device 100 includes a lifting device 110 and a positioning assembly 120 for positioning the PVC pipe.

[0045] The lifting device 110 is responsible for lifting the PVC pipe from the initial position to the height suitable for the hole opening operation. The lifting device 110 can include a hydraulic cylinder, a pneumatic cylinder, an electric lifting platform, or other forms of lifting mechanism. The role of the positioning assembly 120 is to ensure that the PVC pipe maintains the correct position and posture during the lifting process. This can include clamping components, guiding components, or other positioning mechanisms to ensure that the pipe does not shift or rotate during lifting. The design of the positioning assembly 120 needs to take into account the size and weight of the PVC pipe to ensure the stability of the pipe during the entire lifting process. This embodiment improves the accuracy of the support device 100 by combining the lifting device 110 and the positioning assembly 120. The lifting device 110 provides the necessary vertical movement, while the positioning assembly 120 ensures the stability of the PVC pipe during the entire lifting process. This combination not only improves the automation level of the hole opening machine, but also ensures the accuracy of the hole opening operation.

[0046] Further, the positioning assembly 120 includes a first pulley 130 and a second pulley 140 spaced apart on the lifting device 110, the axial direction of the first pulley 130 and the second pulley 140 is parallel to the axial direction of the PVC pipe, and the distance between the first pulley 130 and the second pulley 140 is less than the diameter of the PVC pipe, so that the PVC pipe can be placed on the first pulley 130 and the second pulley 140.

[0047] The positioning assembly 120 includes two pulleys, namely the first pulley 130 and the second pulley 140, which are spaced apart on the lifting device 110. The design of the pulleys is used to support and position the PVC pipe. The axial direction of the pulleys is parallel to the axial direction of the PVC pipe, which means that the rotation axis of the pulleys is parallel to the center line of the PVC pipe. Since the distance between the pulleys is less than the diameter of the PVC pipe, the PVC pipe can be stably placed in the middle between the two pulleys. The pulleys not only serve as a support, but also guide the PVC pipe to move between the first pulley 130 and the second pulley 140 when placing the PVC pipe. In this way, the PVC pipe automatic hole opening machine can more accurately position the pipe to the preset position for subsequent hole opening operations.

[0048] Further, the lifting device 110 includes a mounting base 150, a lifting plate 160 movably mounted on the mounting base 150 and movable in the vertical direction, and a lifting drive device 170 for driving the lifting plate 160 to move in the vertical direction. The first pulley 130 and the second pulley 140 are arranged on the lifting plate 160.

[0049] The mounting base 150 is a fixed part of the lifting device 110, which provides support and mounting basis for the lifting plate 160 and the lifting drive device 170. The lifting plate 160 is a movable part, which is mounted on the mounting base 150 and movable in the vertical direction. The movement of the lifting plate 160 allows the PVC pipe to be lifted to different heights to adapt to the needs of the opening operation. The lifting drive device 170 is responsible for driving the lifting plate 160 to move in the vertical direction. This device can be a hydraulic cylinder, a pneumatic cylinder, an electric lifting mechanism or other forms of driver.

The opening component 320 is connected to the first sliding block 340.

[0051] The first sliding rail 330 is a guide component of the first left-right moving device 310, which is used to guide the moving direction of the first sliding block 340. The third driving device 350 is connected to the first sliding block 340 and is used to drive the first sliding block 340 to slide along the first sliding rail 330. The third driving device 350 can be a motor, a pneumatic cylinder or other types of drivers, which is responsible for providing the power for the movement of the sliding block. The opening component 320 is connected to the first sliding block 340, which means that when the first sliding block 340 moves, the opening component 320 will also move. This connection ensures that the opening component 320 can move accurately in the left-right direction under the guidance of the first sliding rail 330 to perform the opening operation.

[0052] In some embodiments, the front-back moving device 400 includes a front-back sliding rail 420, a front-back sliding block 410, and a fourth driving device 430. The front-back sliding rail 420 is in sliding cooperation with the front-back sliding block 410.
