[0024] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0026] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0027] like Figures 1 to 4The reinforced polyethylene pipe cutting device shown in the figure includes a base 1. Four supporting legs can be installed on the bottom surface of the base 1 to raise the height of the base 1. Fixed blocks 2 are symmetrically installed on the top surface of the base 1. One side of the two fixed blocks 2 is provided with a through groove 12. The through groove 12 on one side of one of the fixed blocks 2 is set through, so that the polyethylene pipe can pass through the through groove 12 set, and one end of the polyethylene pipe passing through the through groove 12 is against the inner wall of one side of the other through groove 12, which is convenient for fixing it. One side of the two fixed blocks 2 is provided with a fixing structure for fixing the polyacetic acid pipe, and the fixing structure includes two bolts 13 threadedly connected to the top surfaces of the two fixed blocks 2 and a rotatable connection at the bottom of the two bolts 13. The two pressure plates 14 at the ends are both arranged in the inner cavity of the two through grooves 12, and the bottom end of the bolt 13 is penetrated by the top surface of the fixing block 2. When the polyethylene tube is placed inside the two through grooves 12, the two bolts 13 are rotated so that the two bolts 13 can rotate on the top surface of the fixing block 2, so that the two bolts 13 drive the pressure plate 14 to move downward through the threaded connection with the fixing block 2, so that the two pressure plates 14 can squeeze and fix the polyethylene tube placed in the inner cavity of the through groove 14, which is convenient for subsequent cutting, and the two side surfaces of the two pressure plates 14 are in friction contact with the inner walls on both sides of the through groove 12, which can limit the pressure plate 14 and prevent the pressure plate 14 from rotating with the bolt 13.

[0028] The top surface of the base 1 is provided with a movable box 3 between the two fixed blocks 2. Both sides of the movable box 3 are provided with perforations 4 for the polyacetic acid tube to pass through. The polyethylene tube passing through one of the slots 12 will first pass through the two perforations 4 and then rest against the inner wall of one side of the other slot 12, so that the position where the polyethylene tube needs to be cut can be inside the movable box 3. The bottom surfaces of the two slots 12 and the bottom surfaces of the perforations 4 are at the same horizontal plane, thereby ensuring that the polyethylene tubes entering the two slots 12 and the two perforations 4 will be in a parallel state, which is convenient for subsequent cutting. A collection box 5 for collecting debris is placed on the bottom surface of the inner cavity of the movable box 3, so that when the polyethylene tube is cut in the movable box 3, the generated debris will fall into the collection box 5, and through the restriction of the movable box 3, the generated debris will be prevented from flying around. The setting between the collection box 5 and the movable box 3 is similar to a drawer, so that the collection box 5 can be taken out from the movable box 3. After cutting the polyethylene tube, the collection box 5 can be taken out from the inside of the movable box 3 for processing.

[0029] The top surface of the movable box 3 is fixedly mounted with a cylinder 6, the piston rod of the cylinder 6 passes through the movable box 3 and is fixedly connected to a lifting plate 7, so that the lifting plate 7 is arranged in the inner cavity of the movable box 3, and the bottom surface of the lifting plate 7 is symmetrically connected with four springs 8, and the free ends of each two springs 8 are fixedly connected with a pressure block 9 for limiting the perforation 4, and the opposite side surfaces of the lifting plate 7 and the two pressure blocks 9 are in friction contact with the inner walls on both sides of the movable box 3 respectively. After the position where the polyethylene tube needs to be cut is inside the movable box 3, the cylinder 6 is turned on so that the cylinder 6 drives the lifting plate 7 downward. Move, so that the lifting plate 7 can drive the pressing block 9 to move downward through the spring 8, so that the bottom surface of the pressing block 9 can be against the top surface of the polyethylene tube, and the width of the pressing block 9 is greater than the diameter of the perforation 4, so that after the pressing block 9 is against the top surface of the polyethylene tube, one side of the pressing block 9 will limit the perforation 4, improve the sealing of the perforation 4, reduce the situation that debris will pass through the perforation 4 when the polyethylene tube is cut, improve the effect of debris processing, avoid the situation that debris will accumulate on the top surface of the base 1 and pollute the working environment, and reduce the impact on the physical and mental health of the staff.

[0030] The bottom surface of the lifting plate 7 is connected to a cutting structure for cutting the polyethylene pipe between the two pressing blocks 9, and the cutting structure is set to an existing structure. The height of the bottom surface of the cutting structure is higher than the height of the bottom surfaces of the two pressing blocks 9, so that the two pressing blocks 9 will contact the polyethylene pipe before the cutting structure. When the two pressing blocks 9 are against the polyethylene pipe, the lifting plate 7 continues to move downward to squeeze the spring 8, so that the cutting structure can contact the polyethylene pipe and then perform the cutting process.

[0031] Four slide bars 10 are installed on the bottom surface of the lifting plate 7 and on one side of the spring 8. The top surfaces of the two pressure blocks 9 are symmetrically provided with slide grooves 11 adapted to two of the slide bars 10, so that when the lifting plate 7 squeezes the spring 8 to move downward, it will drive the slide bar 10 to move in the inner cavity of the slide groove 11, so that the slide bar 10 and the slide groove 11 can assist the movement of the lifting plate 7 and the pressure block 9, and can also limit the pressure block 9 so that the pressure block 9 can only move longitudinally.

[0032] Rectangular blocks 15 are fixedly installed on both sides of the two fixed blocks 2, and a connecting rod 16 is fixedly connected between each two rectangular blocks 15. The movable box 3 is slidably sleeved on the circumference of the two connecting rods 16, so that the movable box 3 can be moved laterally on the top surface of the base 1 through the connecting rod 16, so that different positions of the polyethylene tube can enter the interior of the movable box 3, which is convenient for cutting polyethylene tubes with different lengths. A hydraulic cylinder 17 is fixedly installed on one side of one of the fixed blocks 2, and the piston rod of the hydraulic cylinder 17 is fixedly connected to one side of the movable box 3, so that the hydraulic cylinder 17 can drive the movable box 3 to move along the circumference of the connecting rod 16. The movable box 3 is movable, which is convenient for the staff to move the movable box 3. A scale mark 19 is installed on the top surface of the base 1 and on one side of the movable box 3. A pointer 18 is installed on the side of the movable box 3 facing the scale mark 19, and the pointer 18 and the cutting disk of the cutting mechanism are in the same longitudinal horizontal position, so that when the movable box 3 moves, the pointer 18 will be driven to move, and the pointer 18 will move along the scale mark 19. The distance required to cut the polyethylene tube can be judged by the position of the pointer 18 pointing to the scale mark 19, so that the polyethylene tube can be cut. A transparent baffle can be installed on one side of the movable box 3 to facilitate observation of the cutting situation inside the movable box 3.

[0033] Working principle:

[0034] The reinforced polyethylene pipe cutting device passes the polyethylene pipe through one of the through slots 12 and through the two through holes 4 and against the other through slot 12. At this time, the two bolts 13 are turned to allow the two pressure plates 14 to squeeze the polyethylene pipe, thereby achieving a fixing effect. At this time, the pneumatic hydraulic cylinder 17 is turned on to drive the movable box 3 to move, and cooperate with the pointer 18 and the scale mark 19 to allow the polyethylene pipe to enter the interior of the movable box 3 at the position where it needs to be cut. At this time, the cylinder 6 is turned on to drive the lifting plate 7 to move downward, so that the lifting plate 7 is moved downward by four springs. 8 drives the two pressing blocks 9 to move downward, so that the two pressing blocks 9 can squeeze the polyethylene tube and limit the perforation 4. At this time, the lifting plate 7 continues to move downward, so that the cutting structure on the bottom of the lifting plate 7 can press against the polyethylene tube, thereby performing the cutting process. The debris generated during the cutting process will fall into the collection box 5, so that the setting of the movable box 3 and the collection box 5 can avoid the situation where the debris flies around during the cutting process, and it is also convenient to collect the debris, avoiding the inconvenience of the debris accumulating on the surface of the base 1, and preventing the staff from inhaling it into the body and affecting their physical and mental health.
