Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe fitting manufacturing technology, and in particular to a cutting device for producing plastic pipe fittings that prevents misalignment. Background Technology
[0002] Plastic pipes are generally made from synthetic resin, namely polyester, with the addition of stabilizers, lubricants, plasticizers, etc., and are processed by extrusion in a pipe-making machine using the "plastic" method. They are mainly used for water supply systems, drainage, ventilation and sewage pipes in buildings, underground drainage systems, rainwater pipes, and conduits for electrical wiring installation. Cutting is one of the key processes in their manufacturing.
[0003] Traditional plastic pipe cutting equipment often uses single-sided clamping or single-point fixing. During the cutting process, the pipe is easily displaced or rotated by the cutting force, resulting in uneven cuts or even scrap. In addition, traditional clamps have fixed dimensions, requiring frequent clamp changes to adapt to different pipe specifications, which is cumbersome and inefficient. Therefore, this utility model provides a cutting equipment for the production of plastic pipes that prevents displacement. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a dynamically adjustable anti-deviation mechanism and an adaptive clamping assembly to solve the deviation problem during the cutting process of plastic pipe fittings, while realizing rapid switching and stable clamping of multiple pipe fitting specifications.
[0005] To solve the problems of the prior art, the technical solution of this utility model is as follows: A cutting device for producing plastic pipe fittings with anti-deviation function, including a cutting table, a cutting blade on the cutting table, and two anti-deviation mechanisms on the top of the cutting table. The two anti-deviation mechanisms are located on the left and right sides of the cutting blade, respectively, for clamping the plastic pipe fittings at the positions on both sides of the cutting blade. The right anti-deviation mechanism is fixedly connected to the cutting table, and an adjusting plate is fixedly connected to the bottom of the left anti-deviation mechanism. An adjusting groove is opened on the top of the cutting table, and the inner wall of the adjusting groove is slidably connected to the outer wall of the adjusting plate. An adjusting mechanism is provided on the top of the cutting table for adjusting and moving the position of the left anti-deviation mechanism.
[0006] Preferably, the anti-deviation mechanism includes a fixed plate, which is fixedly connected to a cutting table or an adjusting plate. A fixed ring is fixedly connected to the top of the fixed plate, and a rotating ring is rotatably connected to the outer wall of the fixed ring. The rotating ring is driven by a pneumatic component. A rotating plate is fixedly connected to one side of the rotating ring, and a clamping plate is fixedly connected to one side of the rotating plate. The clamping plate is connected to the fixed ring via a sliding component. A feeding component is provided on one side of the clamping plate. There are four clamping plates, which are staggered to form a square channel in the middle. The pneumatic component includes a cylinder, the top of which is rotatably connected to the outer wall of the rotating ring, and the bottom of which is rotatably connected to the cutting table or adjusting plate. The sliding component includes a sliding rod, one end of which is fixedly connected to one end of the clamping plate. A sliding plate is fixedly connected to one side of the fixed ring, and the sliding rod passes through the sliding plate and can slide relative to the sliding plate. The feeding component includes a ball bearing, which is rotatably connected to the inner wall of a semi-circular groove opened on the clamping plate.
[0007] Preferably, the adjusting mechanism includes a threaded rod, one end of which is rotatably connected to the inner wall of the adjusting groove. The outer wall of the threaded rod passes through the adjusting plate and can rotate relative to the adjusting plate. The cutting table drives the threaded rod to rotate through a driving assembly. The driving assembly includes a motor, one side of which is fixedly connected to the inner wall of the adjusting groove. One end of the motor output shaft is fixedly connected to one end of the threaded rod through a coupling.
[0008] Compared with the prior art, the advantages of this utility model are as follows:
[0009] This invention uses a cylinder to drive a rotating ring to rotate around the central axis of a fixed ring. The rotating ring drives a rotating plate to rotate, which in turn moves one end of a clamping plate. The clamping plate then moves a sliding rod along the sliding plate, causing the clamping plate to gradually approach and clamp the plastic pipe. Once the clamping plate firmly clamps the plastic pipe, the cutting blade starts to move, effectively counteracting the lateral force generated during the cutting process, preventing the pipe from shifting or rotating, ensuring a clean cut, and being compatible with various specifications of plastic pipes without the need to change clamps. The clamping plate has a built-in ball bearing structure, which allows the pipe to slide freely axially even when clamped, reducing feeding resistance and lowering the risk of scratches on the pipe surface.
[0010] This invention uses a starting motor to drive a threaded rod to rotate, which in turn drives an adjusting plate to slide along the inner wall of the adjusting groove. The adjusting plate adjusts the position of the left anti-deviation mechanism, allowing for the cutting of pipes of different sizes as needed. The distance between the two anti-deviation mechanisms can be adjusted to suit the required pipe sizes, enabling digital control of the pipe cutting length. This reduces the time required to change fixtures or adjust equipment, and improves production efficiency. Attached Figure Description

[0016] 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.
[0017] Please see Figure 1-4 A cutting device for producing plastic pipe fittings with anti-deviation features includes a cutting table 1, which serves as the foundation of the device and supports the entire cutting process. Cutting blades 2 are mounted on the cutting table 1, and these blades cut the plastic pipe fittings. The connection between the cutting table 1 and the cutting table 1 is existing technology. Two anti-deviation mechanisms are located on the top of the cutting table 1, on the left and right sides of the cutting blades 2, respectively, to clamp the plastic pipe fittings at their positions on either side of the blades 2, preventing them from shifting during cutting. The right-side anti-deviation mechanism is fixedly connected to the cutting table 1, while the bottom of the left-side anti-deviation mechanism is fixedly connected to an adjusting plate 3. An adjusting groove 4 is formed on the top of the cutting table 1, and the inner wall of the adjusting groove 4 is slidably connected to the outer wall of the adjusting plate 3. The adjusting groove 4 and the adjusting plate 3 provide a sliding track for the left-side anti-deviation mechanism, allowing it to move within a certain range. An adjustment mechanism is also provided on the top of the cutting table 1 to adjust the position of the left-side anti-deviation mechanism to accommodate plastic pipe fittings of different sizes.
[0018] Please see Figure 1-4The anti-deviation mechanism includes a fixed plate 5, which is fixedly connected to the cutting table 1 or the adjusting plate 3. A fixed ring 6 is fixedly connected to the top of the fixed plate 5, and a rotating ring 7 is rotatably connected to the outer wall of the fixed ring 6. The rotating ring 7 is driven by a pneumatic component. A rotating plate 8 is fixedly connected to one side of the rotating ring 7, and a clamping plate 9 is fixedly connected to one side of the rotating plate 8. The clamping plate 9 is connected to the fixed ring 6 through a sliding component. A feeding component is provided on one side of the clamping plate 9. There are four clamping plates 9, which are staggered to form a square channel in the middle. The pneumatic component includes a cylinder 10, which is connected to an external oil circuit. The top of the cylinder 10 is rotatably connected to the outer wall of the rotating ring 7, and the bottom of the cylinder 10 is rotatably connected to the cutting table 1 or the adjusting plate 3. The pneumatic component drives the rotation of the rotating ring 7, thereby moving the clamping plate 9 to clamp the plastic pipe. The sliding assembly includes a sliding rod 11, one end of which is fixedly connected to one end of the clamping plate 9. A sliding plate 12 is fixedly connected to one side of the fixing ring 6. The sliding rod 11 passes through the sliding plate 12 and can slide relative to the sliding plate 12. The sliding assembly allows the clamping plate 9 to slide in a certain direction of the fixing ring 6 to accommodate plastic pipes of different diameters. The feeding assembly includes a ball bearing 13, which is rotatably connected to the inner wall of a semi-circular groove on the clamping plate 9. The feeding assembly helps the plastic pipe smoothly enter the clamping position. The cylinder 10 drives the rotating ring 7 to rotate around the central axis of the fixed ring 6. The rotating ring 7 drives the rotating plate 8 to rotate, and the rotating plate 8 drives one end of the clamping plate 9 to move. The clamping plate 9 drives the sliding rod 11 to slide along the sliding plate 12, so that the clamping plate 9 gradually approaches and clamps the plastic pipe. After the clamping plate 9 firmly clamps the plastic pipe, the cutting blade 2 starts to start, which can effectively counteract the lateral force generated during the cutting process, prevent the pipe from shifting or rotating, ensure a flat cut, and be compatible with various specifications of plastic pipes without the need to change the clamp. The clamping plate 9 has a built-in rolling ball 13 structure, which can still keep the pipe axially free to slide in the clamping state, reduce feeding resistance, and reduce the risk of scratches on the pipe surface.
[0019] Please see Figure 2The adjusting mechanism includes a threaded rod 14, one end of which is rotatably connected to the inner wall of the adjusting groove 4. The outer wall of the threaded rod 14 passes through the adjusting plate 3 and can rotate threadedly relative to the adjusting plate 3. The cutting table 1 drives the threaded rod 14 to rotate via a drive assembly, which includes a motor 15. The motor 15 is connected to an external power source and is a three-phase asynchronous motor. One side of the motor 15 is fixedly connected to the inner wall of the adjusting groove 4, and one end of the output shaft of the motor 15 is fixedly connected to one end of the threaded rod 14 via a coupling. By starting the motor 15, the threaded rod 14 is driven to rotate, and the threaded rod 14 drives the adjusting plate 3 to slide along the inner wall of the adjusting groove 4. The adjusting plate 3 adjusts the position of the left anti-deviation mechanism, thereby allowing for the cutting of pipe fittings of different sizes as needed. The distance between the two anti-deviation mechanisms can be adjusted to suit the required pipe fitting dimensions, achieving digital control of the pipe fitting cutting length, reducing the time spent changing fixtures or adjusting equipment, and improving production efficiency.
[0020] In use, the operator cuts pipe fittings of different sizes as needed. The motor 15 is started, driving the threaded rod 14 to rotate. The threaded rod 14 drives the adjusting plate 3 to slide along the inner wall of the adjusting groove 4. The adjusting plate 3 adjusts the position of the left anti-deviation mechanism until the distance between the two anti-deviation mechanisms is suitable for the required pipe fitting size. The plastic pipe fitting to be cut is inserted along the square channel in the middle of the four clamping plates 9 until the plastic pipe fitting is positioned between the clamping plates 9 on both sides of the cutting blade 2. The cylinder 10 is started, driving the rotating ring 7 to rotate around the central axis of the fixed ring 6. The rotating ring 7 drives the rotating plate 8 to rotate, and the rotating plate 8 drives the clamping... As one end of the holding plate 9 moves, the clamping plate 9 drives the sliding rod 11 to slide along the sliding plate 12, causing the clamping plate 9 to gradually approach and clamp the plastic pipe. The rolling ball 13 plays an auxiliary role in the clamping process, helping the plastic pipe to smoothly enter the clamping position and reducing friction and resistance. After the clamping plate 9 firmly clamps the plastic pipe, the cutting blade 2 starts to cut at a preset speed and path. The cutting blade 2 moves along the axial direction of the plastic pipe and applies sufficient cutting force to ensure the accuracy and depth of the cut. The anti-deviation mechanism plays a key role in the cutting process, ensuring that the pipe does not deviate or shake during the cutting process.
