[0002] Plastic pipes are hollow tubular materials made from high molecular polymers as the main raw material through processes such as extrusion molding or injection molding. They have advantages such as being lightweight, corrosion-resistant, and wear-resistant, and are widely used in fluid transportation in industry, construction, and special environments. During the reprocessing of pipes, they need to be cut to the required length using cutting equipment.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figures 1-4 A precision length cutting device for plastic pipes includes a base 1, with several legs 23 installed on the bottom edge of the base 1, and a conveyor table 2 installed on the top of the base 1 via several support rods 20. A control cabinet 28 is installed on one side of the conveyor table 2, and a controller is installed inside the control cabinet 28. The controller is one of a control motherboard, a host computer, or a PLC logic controller.

[0032] like Figure 1 and Figure 2 As shown, a mounting bracket 6 is installed on one side of the top of the base 1. The mounting bracket 6 is L-shaped and has a U-shaped seat 7 at its bottom. The top of the U-shaped seat 7 is connected to the mounting bracket 6 through a first telescopic mechanism 5. A cutting wheel 9 is rotatably connected inside the U-shaped seat 7. The bottom of the cutting wheel 9 extends to the outside of the U-shaped seat 7, and one end of the cutting wheel 9 is connected to a first drive motor 8 through a gearbox fixed to the side of the U-shaped seat 7. The first drive motor 8 is fixed to the side of the gearbox. The first telescopic mechanism 5 is one of an electric push rod, a cylinder, or a hydraulic rod. Both the first telescopic mechanism 5 and the first drive motor 8 are connected to a controller through wires. In actual demonstration, the first drive motor 8 can drive the cutting wheel 9 to rotate, and the first telescopic mechanism 5 can adjust the height of the cutting wheel 9.

[0033] like Figure 1 and Figure 5 As shown, several pairs of mounting seats 22 are symmetrically installed on the top of the conveyor platform 2. Each pair of mounting seats 22 is equipped with a conveyor roller 3. Each conveyor roller 3 located on the same side is equipped with a sprocket 29 at one end. Adjacent sprockets 29 are connected by a chain. The end of one of the conveyor rollers 3 located on the same side is connected to a second drive motor 30. The second drive motor 30 is fixed on the side of one of the mounting seats 22. The second drive motor 30 is connected to the controller through a wire. In actual use, the operator can place the plastic pipe between the conveyor rollers 3, and then control one of the conveyor rollers 3 to rotate through the second drive motor 30. Under the action of the sprocket 29 and the chain, the other conveyor rollers 3 rotate synchronously to convey the plastic pipe.

[0034] It should be noted that, as Figure 1 As shown, each conveying roller 3 is inclined, and a "V" shape is formed between each pair of conveying rollers 3. In this way, the conveying rollers 3 can position the pipe during the conveying process, so as to avoid the pipe position shifting during cutting.

[0035] like Figure 1 and Figure 4 As shown, a movable platform 24 is provided on one side of the top of the base 1. Strip connecting plates 14 are installed on both sides of the bottom of the movable platform 24, and a fixed plate 27 is installed between the two support rods 20. One side of the fixed plate 27 is connected to the side of one of the strip connecting plates 14 through a second telescopic mechanism 21. The second telescopic mechanism 21 is one of an electric push rod, a cylinder or a hydraulic rod. In actual use, the movable platform 24 can be moved horizontally through the second telescopic mechanism 21, thereby adjusting the distance between the movable platform 24 and the conveyor platform 2.

[0036] It should be noted that, as Figure 1 As shown, the bottoms of the two strip connecting plates 14 are slidably connected to the slide rail fixed on the top of the base 1 via sliders. The slide rails and sliders can guide the strip connecting plates 14, so that the strip connecting plates 14 and the moving platform 24 remain stable when moving.

[0037] like Figure 1 and Figure 2 As shown, a second through groove 17 is provided on the top of the moving platform 24. A strip-shaped connecting block 26 is provided inside the second through groove 17. Both ends of the strip-shaped connecting block 26 extend outside the second through groove 17. A positioning plate 11 is installed on one side of the top of the strip-shaped connecting block 26. A screw 15 is rotatably connected between the two strip-shaped connecting plates 14. The screw 15 passes through the bottom side of the strip-shaped connecting block 26 and is threadedly connected to the strip-shaped connecting block 26. After the moving platform 24 is adjusted to the preset position by the second telescopic mechanism 21, the operator can rotate the screw 15. The screw 15 drives the strip-shaped connecting block 26 to move, thereby precisely adjusting the position of the positioning plate 11. After adjusting the positioning plate 11 to the preset position, the operator places the pipe on the conveying roller 3 for conveying. The conveying roller 3 can convey one end of the plastic pipe to the moving platform 24, so that one end of the plastic pipe abuts against the side of the positioning plate 11. Then, the cutting wheel 9 cuts the pipe to keep the cutting length consistent.

[0038] It should be noted that, as Figure 4 As shown, a horizontal plate 33 is installed on one side of the U-shaped seat 7. Two sliding rods 35 are provided on the top of the horizontal plate 33. The bottom of the two sliding rods 35 slides through the horizontal plate 33, and the bottom of the two sliding rods 35 is connected by a pressure plate 36. A spring 34 is sleeved on the top of each sliding rod 35. The top of each spring 34 abuts against the bottom of the horizontal plate 33, and the bottom of each spring 34 abuts against the top of the pressure plate 36. During cutting, when the first telescopic mechanism 5 pushes the U-shaped seat 7 down, the pressure plate 36 will first contact the top of the pipe conveyed by the conveying roller 3. Then the U-shaped seat 7 will continue to drive the cutting wheel 9 down, the spring 34 will contract, and the pressure plate 36 will press the pipe tightly. When the cutting wheel 9 contacts the pipe and cuts, the pipe can remain stable, improving the cutting accuracy.

[0039] It should be noted that a laser rangefinder 37 is installed on one side of the bottom of the positioning plate 11. The laser rangefinder 37 is flush with the end of the conveyor table 2. The laser rangefinder 37 is connected to the controller through a wire, and the cutting wheel 9 is aligned with one end of the conveyor table 2. In this way, the distance between the end of the positioning plate 11 and the end of the conveyor table 2 can be detected by the laser rangefinder 37, and the detection data can be transmitted to the controller. The controller will then display the detection data on the display screen on the control cabinet 28. In this way, the operator can adjust the position of the positioning plate 11 according to the reading on the display screen, and the adjustment is precise.

[0040] It should be noted that, as Figure 1 and Figure 2 As shown, two support seats 31 are symmetrically installed on the top of the moving table 24. Support rollers 32 are rotatably installed on the adjacent sides of the two support seats 31. The two support rollers 32 are arranged in a "V" shape. The support rollers 32 can support the end of the pipe that is transported to the moving table 24, so that the pipe remains stable during cutting.

[0041] like Figure 1 and Figure 3 As shown, two fixed blocks 18 are installed on one side of the top of the base 1. A top plate 10 is rotatably connected between the two fixed blocks 18. The top plate 10 is located between the conveyor table 2 and the moving table 24. The bottom end of the top plate 10 away from the fixed blocks 18 is connected to a third telescopic mechanism 25 through a hinge seat. The other end of the third telescopic mechanism 25 is fixed to the top of the base 1 through a hinge seat. A guide plate 19 is installed on one side of the base 1. The third telescopic mechanism 25 is one of an electric push rod, a cylinder, or a hydraulic rod. The third telescopic mechanism 25 is connected to the controller through a wire. In actual use, the cut pipe will fall between the moving table 24 and the top plate 10. Then, the operator can push the top plate 10 along the fixed blocks 18 through the third telescopic mechanism 25 to push the cut pipe onto the guide plate 19 and roll it into the collection mechanism along the guide plate 19.

[0042] It should be noted that, as Figure 2 As shown, when the third telescopic mechanism 25 retracts, there is a gap between the top of the top plate 10 and the bottom of the conveying roller 3, so that the top plate 10 will not obstruct the pipe conveyed by the conveying roller 3.

[0043] Specifically, in actual use, the distance between the positioning plate 11 and the end of the conveyor table 2 can be detected by the laser range sensor 37. Then, the operator controls the second telescopic mechanism 21 through the controller. The second telescopic mechanism 21 pushes the strip connecting plate 14 to move, thereby adjusting the moving table 24 to the preset position. Then, the lead screw 15 is rotated, which drives the strip connecting block 26 to move along the second through groove 17. The strip connecting block 26 drives the positioning plate 11 to move horizontally, thereby accurately adjusting the positioning plate 11 to the preset position. Then, the pipe is placed between the conveyor rollers 3, and then driven by the second drive motor 30 under the action of the sprocket 29 and the chain. The moving conveyor roller 3 rotates synchronously, conveying one end of the pipe to the moving table 24, so that the end of the pipe abuts against the side of the positioning plate 11. Then, the first telescopic mechanism 5 is controlled to extend, driving the cutting wheel 9 to move down. At the same time, the operator controls the first drive motor 8 to work through the controller. The first drive motor 8 drives the cutting wheel 9 to rotate, so that the cutting wheel 9 cuts the pipe. After the cutting is completed, the controller controls the third telescopic mechanism 25 to extend. The third telescopic mechanism 25 pushes the top plate 10 to rotate along the fixed block 18, pushing the cut pipe out from between the support rollers 32. The pipe rolls along the top plate 10 to the guide plate 19 and moves along the guide plate 19 into the collection mechanism, making it convenient to pick up the material.

[0044] Furthermore, such as Figure 1 and Figure 2 As shown, the top of the moving platform 24 is also provided with at least one first through groove 16. A limit rod 13 is installed inside the first through groove 16. A limit plate 12 is slidably sleeved on the side of the limit rod 13. One side of the limit plate 12 is fixed on the side of the positioning plate 11. The positioning plate 11 can be limited by the cooperation of the limit rod 13 and the limit plate 12, so that the positioning plate 11 remains stable.

[0045] Furthermore, such as Figure 1 As shown, at least one guide rod 4 is vertically installed on the top of the U-shaped seat 7. The top of the guide rod 4 slides through the mounting frame 6, and the guide rod 4 can support the U-shaped seat 7, so that the U-shaped seat 7 remains stable.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
