Technical Field
[0001] The utility model relates to the technical field of PE drainage pipes, in particular to a cutting device for producing PE drainage pipes. Background Art
[0002] The PE (polyethylene) material of PE drainage pipes is widely used in the field of water pipe manufacturing due to its high strength, corrosion resistance, and non-toxicity. It will not rust and is an ideal pipe to replace ordinary iron water pipes. The production of PE drainage pipes is done by melting the polyethylene raw materials with an injection molding machine, and then cutting them according to the required specifications.
[0003] However, the cutting machine part of the existing cutting device for PE drainage pipe production mostly adopts downward pressure cutting. The vibration generated during cutting can easily cause the cutting machine to rebound upward, causing the cutting blade to cut the current part again, affecting the cutting accuracy. The existing cutting device does not have left and right auxiliary limiters when cutting PE drainage pipes. The PE drainage pipe is prone to sliding left and right under the drive of the cutting blade, which is inconvenient to cut and affects the cutting effect. In order to solve the shortcomings of the existing technology, we propose a cutting device for PE drainage pipe production. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1-Figure 4 As shown, a conveyor belt 9 is provided on one side of the cutting device body 1, and a roller 10 is connected to the conveyor belt 9 for internal transmission. A bottom plate 11 is provided at the bottom of the conveyor belt 9, and a fixed plate 12 is detachably installed on the top of the bottom plate 11. First movable plates 13 are hinged at both ends of the fixed plate 12, and a second movable plate 14 is rotatably connected to one end of the first movable plate 13. The second movable plate 14 is in a "C" shape, and rollers 15 are rotatably connected to both ends of the second movable plate 14. A second hydraulic push rod 16 is symmetrically detachably installed on the top of the fixed plate 12, and an elastic rubber column 17 is detachably installed on one end of the second push rod of the second hydraulic push rod 16, and one end of the elastic rubber column 17 is detachably installed on one side of the first movable plate 13. The staff starts the second push rod of the second hydraulic push rod 16 to push the elastic rubber column 17 to push the first movable plate 13. The plate 13 rotates and opens on the fixed plate 12, and the first movable plate 13 drives the second movable plate 14 to drive the roller 15 to open. The staff places the PE drain pipe to be cut on the conveyor belt 9, and rotates the roller 10 to drive the conveyor belt 9 to drive the PE drain pipe to be cut to the first movable plate 13. Then the staff starts the second hydraulic push rod 16 to retract the second push rod to drive the elastic rubber column 17 to drive the first movable plate 13 to drive the second movable plate 14 to drive the roller 15 to return to the original position. The first movable plate 13 pulls the second movable plate 14 under the tension of the elastic force of the elastic rubber column 17 to drive the roller 15 to press on the side of the PE drain pipe to be cut. The other side of the PE drain pipe to be cut is pressed by the same second movable plate 14 and roller 15, thereby assisting in limiting the left and right sides of the PE drain pipe to be cut.
[0023] When it is necessary to cut PE drain pipes of different sizes, repeat the above steps, and the second movable plate 14 drives the roller 15 to press on the side of the PE drain pipe of the new size. Due to the "c" shape design of the second movable plate 14, the roller 15 on the second movable plate 14 can press and limit PE drain pipes of different sizes, which has a wider range of applications and stronger practicality.
[0024] like Figure 1 and Figure 2 As shown, a cutting device for PE drainage pipe production includes a cutting device body 1, a first hydraulic push rod 2 is detachably installed on the top of the cutting device body 1, a slide groove is symmetrically opened on the top of the cutting device body 1, a fixing rod 3 is detachably installed on one end of the inner wall of the slide groove opened by the cutting device body 1, and a fixing frame 4 is movably penetrated at one end of the fixing rod 3, a push plate 5 is detachably installed on one end of the first push rod of the first hydraulic push rod 2, one side of the push plate 5 is detachably installed with one side of the fixing frame 4, one end of the fixing frame 4 is detachably installed with a protective frame 6, one side of the protective frame 6 is detachably installed with a driving motor 7, and one end of the output end of the driving motor 7 is detachably installed with a cutting blade 8, fixing the PE to be cut. After the PE drain pipe is positioned, the driving motor 7 is started, and the output end of the driving motor 7 drives the cutting blade 8 to rotate. Then the first push rod of the first hydraulic push rod 2 is started to push the push plate 5 to drive the fixed frame 4 to drive the protective frame 6 to drive the driving motor 7 and the cutting blade 8. The cutting blade 8 contacts the side of the PE drain pipe to be cut for cutting. The staff rotates the PE drain pipe to be cut. Under the limitation of the second movable plate 14 and the roller 15, the rotating PE drain pipe to be cut is cut from the side by the cutting blade 8. Under the left and right limitation of the second movable plate 14 and the roller 15, the cutting blade 8 cuts the PE drain pipe to be cut from the side and is not easy to shake and rebound. The cutting is more accurate and the cutting effect is better.
[0025] How it works
[0026] It should be noted that the utility model is a cutting device for producing PE drainage pipes. When in use, the first hydraulic push rod 2 is first started. The first push rod of the first hydraulic push rod 2 drives the push plate 5 to drive the fixed frame 4 to drive the protective frame 6 to drive the drive motor 7 and the cutting blade 8 to move backward. Then the second hydraulic push rod 16 is started. The second push rod of the second hydraulic push rod 16 drives the elastic rubber column 17 to push the first movable plate 13 to rotate and open on the fixed plate 12. The first movable plate 13 drives the second movable plate 14 to drive the roller 15 to open. Then the PE drainage pipe to be cut is placed on the conveyor belt 9. The conveyor belt 9 is driven by rotating the roller 10 to drive the PE drainage pipe to be cut to the first movable plate 13. The second hydraulic push rod 16 is started to retract the second push rod. The second push rod of the second hydraulic push rod 16 is retracted, driving the elastic rubber column 17 to drive the first movable plate 13 to drive the second movable plate 14 to drive the roller 15 to return to its original position, and the returned roller 15 first contacts the PE drain pipe to be cut, and one side of the roller 15 is in contact with the PE drain pipe to be cut. After being subjected to the resistance of the PE drain pipe to be cut, the roller 15 drives the second movable plate 14 to rotate on the first movable plate 13 until the second push rod is completely retracted. The first movable plate 13 pulls the second movable plate 14 under the tension of the elastic force of the elastic rubber column 17 itself, driving the roller 15 to press on the side of the PE drain pipe to be cut, and the other side of the PE drain pipe to be cut is pressed by the same second movable plate 14 and roller 15, thereby achieving the purpose of auxiliary limiting the left and right sides of the PE drain pipe to be cut.
[0027] After fixing the position of the PE drain pipe to be cut, start the drive motor 7, the output end of the drive motor 7 drives the cutting blade 8 to rotate, and then start the first push rod of the first hydraulic push rod 2 to push the push plate 5 to drive the fixed frame 4 to drive the protective frame 6 to drive the drive motor 7 and the cutting blade 8, the cutting blade 8 contacts the side of the PE drain pipe to be cut for cutting, and the staff rotates the PE drain pipe to be cut. Under the limitation of the second movable plate 14 and the roller 15, the rotating PE drain pipe to be cut is cut from the side by the cutting blade 8. Under the left and right limitation of the second movable plate 14 and the roller 15, the cutting blade 8 cuts the PE drain pipe to be cut from the side without shaking and rebounding, thereby achieving the purpose of stably cutting the PE drain pipe to be cut.
