[0002] PE is polyethylene plastic, the most basic type of plastic. Plastic bags, cling film, etc. are all made of PE. PE pipes include medium-density polyethylene pipes and high-density polyethylene pipes. Compared with steel pipes, the construction process is simpler and it has a certain degree of flexibility. PE pipes are widely used and have high practicality, so they are very popular. During the production of PE pipes, the end faces need to be ground to ensure that the end faces are flat.

[0003] In existing technologies, it is not convenient to fix PE pipes when the end face is trimmed. If the PE pipe moves during cutting and grinding, it will affect the flatness of the PE pipe end face. In addition, when cutting PE pipes, a lot of debris will be generated near the cutting equipment. Existing technologies are not convenient to deal with the flying debris at the same time as cutting, which causes the debris to have a great impact on the working environment.

[0004] Therefore, this utility model provides a PE pipe end face trimming machine. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problems of PE pipe end face trimming, such as the difficulty in fixing PE pipes during end face trimming, the impact on the flatness of the PE pipe end face if the PE pipe moves during cutting and grinding, and the large amount of debris generated near the cutting equipment during cutting, which is difficult to handle with existing technologies, causing significant impact on the working environment, this utility model proposes a PE pipe end face trimming machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A PE pipe end face trimming machine of this utility model includes a base, a bracket fixedly connected to the top of the base, a base plate fixedly connected to the top of the bracket, a support frame fixedly connected to the top of the base, two hydraulic cylinders symmetrically fixedly connected to the bottom of the support frame, the output ends of the two hydraulic cylinders are jointly fixedly connected to a top plate, the top of the base plate and the bottom of the top plate are both set as arc surfaces, a lifting machine is fixedly connected to the top of the base and the side away from the support frame, a grinding machine is fixedly connected to the output end of the lifting machine, a protective cover is fixedly connected to the outer wall of the grinding machine, a motor is fixedly connected to one side of the base plate, the output end of the motor extends into the interior of the base plate and is fixedly connected to a lead screw, the lead screw is rotatably connected to the base plate, a slider is connected to the outer wall of the lead screw through a lead screw nut pair, the slider is slidably connected to the base plate, and a push block is fixedly connected to the top of the slider.

[0008] Preferably, a first cavity is formed at the top of the base and below the protective cover, and a second cavity is formed inside the base. A connecting groove is formed between the first cavity and the second cavity. A filter plate is slidably connected to the inner wall of the first cavity. The filter plate is installed at an angle. A baffle is fixedly connected to the bottom of the filter plate. The baffle fits against the inner wall of the first cavity. An exhaust fan is fixedly connected to one side of the base. An exhaust pipe is fixedly connected to the input end of the exhaust fan. One end of the exhaust pipe extends into the interior of the first cavity and is located below the filter plate.

[0012] The beneficial effects of this utility model are as follows: 1. The PE pipe end face trimming machine of this utility model clamps the PE pipe by means of the cooperation of the top plate and the bottom plate, so as to avoid shaking during cutting and grinding and affecting the flatness of the end face.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 5 As shown, this utility model provides a technical solution: a PE pipe end face trimming machine, including a base 1, a bracket 2 fixedly connected to the top of the base 1, a base plate 3 fixedly connected to the top of the bracket 2, a support frame 4 fixedly connected to the top of the base 1, two hydraulic cylinders 5 symmetrically fixedly connected to the bottom of the support frame 4, and a top plate 6 fixedly connected to the output ends of the two hydraulic cylinders 5. The top of the base plate 3 and the bottom of the top plate 6 are both set as arc surfaces. A lifting machine 7 is fixedly connected to the top of the base 1 and the side away from the support frame 4. A grinding machine 8 is fixedly connected to the output end of the lifting machine 7. A protective cover 9 is fixedly connected to the outer wall of the grinding machine 8. A motor 10 is fixedly connected to one side of the base plate 3. The output end of the motor 10 extends into the interior of the base plate 3 and is fixedly connected to a lead screw 11. The lead screw 11 is rotatably connected to the base plate 3. A slider 12 is connected to the outer wall of the lead screw 11 through a lead screw nut pair. The slider 12 is slidably connected to the base plate 3. A push block 13 is fixedly connected to the top of the slider 12.

[0018] The above technical solution involves placing the PE pipe on the base plate 3, controlling the top plate 6 to move downwards via the hydraulic cylinder 5, and clamping the PE pipe by the cooperation between the top plate 6 and the base plate 3 to prevent shaking during cutting and grinding, which would affect the flatness of the end face. The motor 10 is started, driving the lead screw 11 to rotate, causing the slider 12 to move closer to the grinder 8, which in turn drives the push block 13 to move closer to the grinder 8. The push block 13 pushes the PE pipe forward, thus facilitating precise control of the grinding position. The grinder 8 is moved downwards via the lifting platform 7, and the end face of the PE pipe is ground by the grinder 8. The protective cover 9 prevents grinding debris from flying everywhere.

[0019] Specifically, the inner walls of the base plate 3 and the top plate 6 are each fixedly connected with several rotating shafts 14 at equal intervals, and the outer walls of the rotating shafts 14 are rotatably connected with pulleys 15.

[0020] Through the above technical solution, the friction between the bottom plate 3 and the top plate 6 on the PE pipe can be reduced by the pulley 15. When the push block 13 moves, it is easy to push the PE pipe forward and avoid wear on the surface of the PE pipe.

[0021] Specifically, a first cavity 16 is formed at the top of the base 1 and below the protective cover 9, and a second cavity 17 is formed inside the base 1. A connecting groove 18 is formed between the first cavity 16 and the second cavity 17. A filter plate 19 is slidably connected to the inner wall of the first cavity 16. The filter plate 19 is installed at an angle. A baffle 20 is fixedly connected to the bottom of the filter plate 19 and fits against the inner wall of the first cavity 16. An exhaust fan 21 is fixedly connected to one side of the base 1, and an exhaust duct 2 is fixedly connected to the input end of the exhaust fan 21. 2. One end of the exhaust duct 22 extends into the interior of the first cavity 16 and is located below the filter plate 19. A feeding assembly is provided on the top of the filter plate 19. The feeding assembly includes a mounting bracket 25, which is fixedly installed on the top of the filter plate 19. One end of the lead screw 11 passes through the base plate 3 and is fixedly connected to a crank 24. A connecting shaft 26 is rotatably connected between the crank 24 and the mounting bracket 25. A drawer 27 is slidably connected inside the second cavity 17 and below the connecting groove 18. One side of the drawer 27 passes through the base 1.

[0022] Through the above technical solution, the connecting groove 18 is blocked by the baffle 20. While grinding the end face of the PE pipe, the exhaust fan 21 is started to allow air to enter through the exhaust pipe 22, thereby creating negative pressure in the first cavity 16. This facilitates the extraction of the grinding debris generated above. After entering the first cavity 16, the debris is filtered by the filter plate 19 and remains on the filter plate 19. When feeding the PE pipe, the exhaust fan 21 is turned off. As the lead screw 11 rotates, it drives the crank 24 to rotate. When the protruding end of the crank 24 rotates to the bottom, it pushes the connecting shaft 26 to move downward, causing the filter plate 19 and the baffle 20 to move downward. When the filter plate 19 passes through the connecting groove 18, the debris accumulated on the filter plate 19 slides down along the slope of the filter plate 19 and enters the second cavity 17 along the connecting groove 18. The drawer 27 can collect the debris in the second cavity 17 and facilitates periodic replacement.

[0023] Specifically, the output end of the exhaust fan 21 is fixedly connected to an air outlet duct 23, one end of which extends between the bottom plate 3 and the top plate 6.

[0024] With the above technical solution, when the exhaust duct 22 starts to extract air, the end of the exhaust duct 23 starts to blow air. The air blown out by the exhaust duct 23 enters the PE pipe, which can blow out the debris that has entered the PE pipe, making it easier to clean the inside of the PE pipe.

[0025] In use, the PE pipe is placed on the base plate 3, and the top plate 6 is moved downward by the hydraulic cylinder 5. The cooperation between the top plate 6 and the base plate 3 clamps the PE pipe, preventing it from shaking during cutting and grinding and affecting the flatness of the end face. The pulley 15 reduces the friction between the base plate 3 and the top plate 6 on the PE pipe, making it easier to push the PE pipe forward and preventing wear on the PE pipe surface. The motor 10 is started, which drives the lead screw 11 to rotate, causing the slider 12 to move closer to the grinder 8, driving the push block. 13 moves closer to the grinder 8, and the PE pipe is advanced forward by the pusher block 13, which facilitates precise control of the grinding position. The grinder 8 is moved downward by the lift 7, and the end face of the PE pipe is ground by the grinder 8. The protective cover 9 prevents grinding debris from flying everywhere, and the baffle 20 blocks the connecting groove 18. While grinding the end face of the PE pipe, the exhaust fan 21 is started, so that air begins to enter through the exhaust pipe 22, thereby filling the first cavity 16. A negative pressure is created at the point where the grinding debris generated above can be easily extracted. After entering the first cavity 16, the debris is filtered by the filter plate 19, causing it to remain on the filter plate 19. When feeding the PE pipe, the exhaust fan 21 is turned off. As the lead screw 11 rotates, it drives the crank 24 to rotate. When the protruding end of the crank 24 rotates to the lower position, it pushes the connecting shaft 26 to move downward, causing the filter plate 19 and the baffle 20 to move downward. When the filter plate 19 passes through the connecting groove 18, the debris accumulated on the filter plate 19 is removed. The debris slides down the slope of the filter plate 19 and enters the second cavity 17 through the connecting groove 18. The drawer 27 can collect the debris in the second cavity 17 and facilitate regular replacement. When the exhaust duct 22 starts to draw air, the end of the exhaust duct 23 starts to blow air. The air blown out of the exhaust duct 23 enters the PE pipe and blows out the debris that has entered the PE pipe, which facilitates the cleaning of the inside of the PE pipe. Similarly, the debris blown out of the PE pipe is drawn onto the filter plate 19 by the exhaust duct 22.
