Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, specifically a plastic pipe length cutting mechanism. Background Technology

[0002] Plastic pipes are a widely used engineering material in water supply, drainage, gas supply, heating and other fields. With their good corrosion resistance, light weight, convenient transportation and construction, and long service life, they have gradually replaced traditional metal and cement pipes.

[0003] A search revealed CN219768362U, which discloses a plastic pipe length-cutting mechanism and plastic pipe cutting equipment, belonging to the field of plastic pipe production equipment. It is used for plastic pipe production and includes a discharge port in the cutting equipment. A cutting blade is positioned above the discharge port and driven by a blade holder drive device. A positioning plate is positioned in the discharge direction of the discharge port. Driven by a plate drive mechanism, the positioning plate moves away from the discharge port when the cutting blade cuts the plastic pipe. When the plastic pipe is being conveyed outward from the discharge port and the cutting blade is not performing a cutting action, the positioning plate, driven by the plate drive mechanism, is positioned in the discharge direction of the discharge port. This application can achieve length control when cutting plastic pipes into plastic pipe rings to a fixed length by adding a plastic pipe length-cutting mechanism, ensuring that the cut plastic pipe rings are always within the standard range. Furthermore, the added plastic pipe length-cutting mechanism can be linked with existing cutting equipment, facilitating equipment improvement and unloading.

[0004] However, in the existing technology, the forming length of plastic pipes after cutting is not convenient to adjust according to production needs, which brings inconvenience to the production work, and therefore needs to be improved. Utility Model Content

[0013] Beneficial effects

[0014] This utility model provides a plastic pipe length-cutting mechanism, which has the following beneficial effects:

[0015] 1. This plastic pipe length-cutting mechanism, by setting a cutting length adjustment mechanism, allows the distance between the strip end plate and the cutting component to be adjusted by sliding the movable rod within the outer casing. Tightening the locking nut on the outside of the threaded column fixes the movable column. A limiting baffle limits the strip end plate, allowing it to rotate to a vertical position. Once the strip end plate is in a vertical position, it limits the plastic pipe, and the cutting component cuts the plastic pipe, thus maintaining a constant forming length after cutting. Compared to existing technologies, this allows operators to adjust the forming length of the cut plastic pipe according to different production needs, providing convenience for workers.

[0016] 2. This plastic pipe length-cutting mechanism, by setting a first contact switch and a second contact switch, allows the first servo motor to rotate clockwise by pressing the second contact switch after the cutting component completes the cutting, thereby releasing the limit of the strip end plate on the end of the plastic pipe. After the cutting component completes the cutting, it will perform a reset movement, and the driving mechanism will transport the plastic pipe from right to left, which can squeeze the cut plastic pipe off for easy collection. When the cutter continues to move upward and touches the first contact switch, it can drive the strip end plate to rotate to a vertical state, thereby limiting the end of the plastic pipe. The entire process is automatically controlled, thus realizing automated cutting and processing of plastic pipes and greatly improving the production efficiency of fixed-length plastic pipes.

[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] Please see Figure 1-4 This utility model provides a technical solution: a plastic pipe length-cutting mechanism, including a pipe limiting plate 1 and a bottom plate 2. The pipe limiting plate 1 has a through hole at its end, through which a plastic pipe 3 is slidably connected. A lower cutting groove is formed in the middle of the pipe limiting plate 1, and a cutting component 4 is positioned above the lower cutting groove. Notches are formed on both sides of the pipe limiting plate 1, and a driving mechanism 5 is provided at the notches to drive the plastic pipe 3 to slide within the through hole. A cutting length adjustment mechanism 6 is fixedly connected to the lower surface of the left end of the pipe limiting plate 1. The cutting length adjustment mechanism 6, the cutting component 4, the driving mechanism 5, and the pipe limiting plate 1 are all fixedly connected to the surface of the bottom plate 2. The cutting length adjustment mechanism 6 includes an outer shell 7, a movable rod 8, a threaded column 9, a locking nut 10, a first servo motor 11, a strip-shaped end plate 12, and a limiting baffle 13. The outer shell 7 is fixedly connected to the lower surface of the pipe limiting plate 1, the movable rod 8 is slidably connected to the inner wall of the outer shell 7, the threaded column 9 is fixedly connected to the surface of the movable rod 8, and the locking nut... The threaded connection 10 is attached to the outer surface of the threaded column 9. The first servo motor 11 and the limiting baffle 13 are both fixedly connected to the left end of the movable rod 8. The strip end plate 12 is fixedly connected to the rotating end of the first servo motor 11, and the right surface of the strip end plate 12 abuts against the left end of the plastic tube 3. By setting the cutting length adjustment mechanism 6, the distance between the strip end plate 12 and the cutting assembly 4 can be adjusted by sliding the movable rod 8 inside the outer casing 7. By tightening the locking nut 10 on the outside of the threaded column 9, the movable column can be fixed. The limiting baffle 13 limits the strip end plate 12, allowing the strip end plate 12 to rotate to a vertical state. After the strip end plate 12 rotates to a vertical state, it can limit the plastic tube 3. The cutting assembly 4 can then cut the plastic tube 3, thus keeping the formed length of the plastic tube 3 after cutting constant. Compared with the prior art, the operator can adjust the formed length of the plastic tube 3 after cutting according to different production needs, providing convenience for the operator.

[0024] The cutting assembly 4 includes a retractable frame 14, a hydraulic push rod 15, a blade holder 16, and a cutting blade 17. The retractable frame 14 is fixedly connected to the surface of the bottom plate 2. The hydraulic push rod 15 is fixedly connected between the blade holder 16 and the retractable frame 14. The cutting blade 17 is fixedly connected to the lower surface of the blade holder 16. It should be noted that the hydraulic push rod 15 operates by reciprocating extension and retraction. By reciprocating extension and retraction of the hydraulic push rod 15, the blade holder 16 and the cutting blade 17 can be driven to make regular up-and-down reciprocating movements.

[0025] The driving mechanism 5 includes an upper positioning plate, a lower positioning plate, two driving wheels 18, two gears 19, and a second servo motor 20. The lower positioning plate is fixedly connected to the surface of the bottom plate 2, and the second servo motor 20 is fixedly connected to the surface of the lower positioning plate. Both driving wheels 18 are rotatably connected to the lower surface of the upper positioning plate. The two gears 19 are respectively fixedly connected to the rotating ends of the driving wheels 18, and the two gears 19 mesh with each other for transmission. The rotating end of one gear 19 is connected to the output end of the second servo motor 20 for transmission, and the rotating end of the other gear 19 is rotatably connected to the surface of the lower positioning plate. The two gears 19 are the same size, and the two driving wheels 18 are also the same size. By setting up the driving mechanism 5, the second servo motor 20 can drive one of the gears 19 and the driving wheel 18 to rotate. By the meshing transmission of the two gears 19, the two driving wheels 18 can be driven to rotate synchronously in opposite directions. By rotating the driving wheels 18, friction is applied to both sides of the plastic tube 3, which enables the plastic tube 3 to move from right to left within the through hole of the tube limiting plate 1.

[0026] A first contact switch 21 is fixedly connected to the inner side of the frame 14 via a crossbeam plate. A second contact switch 22 is provided on the surface of the pipe limiting plate 1. The first and second contact switches 22 are located on the upper and lower sides of the cutter holder 16, respectively. Both the first and second contact switches 22 are electrically connected to the first servo motor 11. By setting the driving mechanism 5 and the pipe limiting plate 1, the plastic pipe 3 can be conveyed from right to left. By setting the first and second contact switches 21 and 22, after the cutting assembly 4 completes the cutting, the cutter holder 16 and the cutting blade 17 will move downward. By pressing the second contact switch 22 on the cutter holder 16, the first servo motor 11 can be controlled to rotate clockwise. The clockwise rotation of the first servo motor 11 can drive the strip end. The plate 12 rotates, thereby releasing the restriction of the strip end plate 12 on the end of the plastic tube 3. After the cutting assembly 4 completes the cutting, it will perform a reset movement. At this time, the knife holder 16 and the cutting blade 17 will move upward. When the cutting blade 17 disengages from the lower blade groove, the driving mechanism 5 will transport the plastic tube 3 from right to left, which can squeeze the cut plastic tube 3 out and make it easier to collect. When the knife holder 16 continues to move upward and touches the first contact switch 21, it can control the first servo motor 11 to rotate counterclockwise, thereby driving the strip end plate 12 to rotate to a vertical state, realizing the restriction of the end of the plastic tube 3. The whole process is automatically controlled, thereby realizing the automated cutting and processing of plastic tube 3, which greatly improves the production efficiency of fixed length plastic tube 3.
