Description

Technical Field

[0001] This utility model relates to the field of PE pipe cutting technology, specifically a cutting device for PE pipe production and processing. Background Technology

[0002] PE is polyethylene plastic, the most basic type of plastic. Plastic bags, cling film, etc., are all made of PE. HDPE is a highly crystalline, non-polar thermoplastic resin. In its natural state, HDPE is milky white, and in thin sections, it is somewhat translucent. PE has excellent resistance to most household and industrial chemicals.

[0003] For example, a cutting device for PE pipe production and processing, disclosed in CN214238535U, includes a worktable. A rotating groove is formed on the front side of the center of the worktable. A blade is fixedly installed inside the rotating groove. A motor is fixedly installed on the right side of the rotating groove, and the output end of the motor is fixedly connected to the blade. A protective cover is fixedly installed outside the blade and is fixedly connected to the rotating groove. Fixing rods are fixedly installed on the left and right rear sides of the outer center of the protective cover. A working groove is formed in the center of the rear side of the worktable. In use, the produced PE pipe is first passed through a pipe block. When the PE pipe needs to be cut, the movement of the PE pipe is paused. Then, the operator pushes the pipe block with both hands, moving the PE pipe towards the blade. Simultaneously, a slider drives a first connecting rod to slide towards the blade inside the working groove. The first connecting rod drives second connecting rods on both sides to move towards the blade.

[0004] The aforementioned patent proposes that the pipe block can both fix the produced PE pipes and clamp them during cutting, so that the cut PE pipes will be neat and uniform and will not be skewed. However, in actual use, the pipe block can only clamp and fix a group of PE pipes at a time, making it difficult for the device to cut multiple groups of PE pipes at the same time, affecting the cutting speed of a large number of PE pipes, and making it inconvenient to use.

[0005] Therefore, we propose a cutting device for PE pipe production and processing to solve the problems mentioned above. Utility Model Content

A support foot is installed at the bottom of the transport plate, and the lower end of the drive cylinder is located inside the top of the support foot.

[0008] The cutting component includes a horizontal bar and side bars installed at both ends of the horizontal bar. The side bars are installed on the top of the constraint plate, and a limit groove is opened on the outer surface of the side bars. A linear cylinder is installed inside the limit groove, and the lower end of the linear cylinder is inside the inclined groove. A cutter is installed between the linear cylinders.

[0009] Preferably, the fixing member includes a movable strip and a threaded hole extending through the middle of the movable strip, and an inverted U-shaped insert frame is installed on the outer surface of the movable strip.

[0010] Preferably, a positioning groove is provided at the top of the constraint plate and at the middle of the tube hole, the lower end of the inverted U-shaped insert frame matches the positioning groove, and the bottom end of the inverted U-shaped insert frame is provided with a ceramic coating B.

[0011] Preferably, a built-in motor is installed at the bottom end of the horizontal bar, a threaded shaft is installed at the output end of the built-in motor, and a limiting circular plate is installed at the top end of the threaded shaft.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figures 1-4A cutting device for PE pipe production and processing includes a transport plate 1 and drive cylinders 12 installed inside the four corners of the transport plate 1. A constraint plate 3 is installed at the top of the drive cylinder 12, and a cutting component 4 is installed at the top of the constraint plate 3. A pipe hole 6 is opened through one side of the middle end where the transport plate 1 and the constraint plate 3 are in contact. Multiple sets of pipe holes 6 are opened. The inner wall of the pipe hole 6 at the top of the transport plate 1 and the inner wall of the pipe hole 6 at the bottom of the constraint plate 3 are both coated with a ceramic coating A11. An inclined groove 13 is opened at the top of the transport plate 1. A cutting groove 31 is opened through the top of the constraint plate 3 at a position corresponding to the inclined groove 13. Cutting components 4 are installed on both sides of the cutting groove 31 at the top of the constraint plate 3. A fixing component 5 is installed on the outer side of the top of the cutting component 4. A support leg 2 is installed at the bottom of the transport plate 1, and the lower end of the drive cylinder 12 is inside the top of the support leg 2.

[0024] The cutting component 4 includes a horizontal bar 44 and side bars 41 installed at both ends of the horizontal bar 44. The side bars 41 are installed on the top of the constraint plate 3, and the outer surface of the side bars 41 has a limiting groove 42. A linear cylinder 43 is installed inside the limiting groove 42, and the lower end of the linear cylinder 43 is inside the inclined groove 13. A cutter 45 is installed between the linear cylinders 43. The two sets of linear cylinders 43 control the position of the cutter 45, which facilitates the cutting of PE pipe.

[0025] The fixing component 5 includes a movable strip 51 and a threaded hole 52 that passes through the middle of the movable strip 51. An inverted U-shaped insert frame 53 is installed on the outer surface of the movable strip 51, which can be used to clamp the PE pipe.

[0026] A positioning groove 32 is provided at the top of the constraint plate 3 and in the middle of the pipe hole 6. The lower end of the inverted U-shaped insert frame 53 matches the positioning groove 32. The bottom end of the inverted U-shaped insert frame 53 is provided with a ceramic coating B54. The ceramic coating B54 will reduce the friction between the PE pipe and the device, making it easier for the PE pipe to move. At the same time, it will protect the surface of the PE pipe and prevent damage to the PE pipe.

[0027] A built-in motor 46 is installed at the bottom of the horizontal bar 44. A threaded shaft 47 is installed at the output end of the built-in motor 46. A limit plate 48 is installed at the top of the threaded shaft 47. The threaded shaft 47 is threaded into the inside of the threaded hole 52, thereby controlling the up and down position of the fixing component 5.

[0028] The inner diameter of the inverted U-shaped insert 53 is the same as the width of the horizontal bar 44, which allows the inverted U-shaped insert 53 to move along both sides of the horizontal bar 44 when it moves down, and restricts the angle of movement of the fixed component 5.

[0029] In this embodiment: the drive cylinder 12 extends, moving the upper constraint plate 3 away from the transport plate 1. The PE pipe is placed in the pipe hole 6 at the top of the transport plate 1. Since multiple sets of pipe holes 6 are opened through the contact end of the transport plate 1 and the constraint plate 3, the number of pipe holes 6 opened for the PE pipe are respectively placed inside the pipe holes 6 at the top of the transport plate 1. The drive cylinder 12 retracts, and the constraint plate 3 moves towards the top surface of the transport plate 1. When the top of the transport plate 1 contacts the bottom of the constraint plate 3, the built-in motor 46 operates, and the threaded shaft 47 rotates. The threaded shaft 47 rotates inside the threaded hole 52, causing the moving bar 51 to move towards the top surface of the horizontal bar 44. The lower end of the inverted U-shaped insert frame 53 is inserted into the positioning groove 32. When the bottom end of the moving bar 51 contacts the PE pipe, the pipe hole 6 at the top of the transport plate 1 and the bottom end of the inverted U-shaped insert frame 53 clamp the PE pipe. The linear cylinder 43 operates, driving the cutter 45 to move down through the cutting groove 31 and cut the PE pipe.

[0030] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 Side blocks 14 are installed on one side of the transport plate 1 and on both sides of the lower end of the tube hole 6. A drive motor 15 is installed on the outer surface of a set of side blocks 14. A rotating shaft 16 is installed at the output end of the drive motor 15. A pusher 17 is installed on the outer surface of the rotating shaft 16. When the pusher 17 is at the top of the rotating shaft 16, the top of the pusher 17 is above the inner bottom of the ceramic coating A11.

[0031] In this embodiment: after the PE pipe is cut for the first time, the built-in motor 46 operates in reverse, the moving bar 51 drives the inverted U-shaped insert frame 53 to move upward, and after the clamping of the PE pipe is released, the drive motor 15 starts to operate, the rotating shaft 16 drives the push bar 17 to rotate, causing one end of the push bar 17 to contact the bottom end of the PE pipe, and the PE pipe is fed and transported. After the drive motor 15 stops operating, the pipe hole 6 at the top of the transport plate 1 and the bottom end of the inverted U-shaped insert frame 53 re-clamp the PE pipe, which is convenient for cutting. The debris generated during cutting is located inside the inclined groove 13, which prevents the debris from flying and affecting the working environment.

[0032] Working principle: The constraint plate 3 moves towards the top surface of the transport plate 1, and the PE pipe is constrained by the constraint plate 3 and the transport plate 1. The built-in motor 46 operates, and the threaded shaft 47 rotates inside the threaded hole 52, causing the moving bar 51 to move towards the top surface of the horizontal bar 44. The PE pipe is clamped by the pipe hole 6 at the top of the transport plate 1 and the bottom end of the inverted U-shaped insert frame 53. The linear cylinder 43 operates, driving the cutter 45 to move down to cut the PE pipe.
