A plastic pipe processing device

Abstract

This utility model discloses a plastic pipe processing device, relating to the field of plastic pipe processing, including a support frame and a plastic pipe. The support frame is equipped with an inner support for supporting the plastic pipe, and the plastic pipe is fitted onto the inner support. A cutter and a long blade for cutting the plastic pipe are arranged on the outer side of the support frame. This utility model, by providing an inner support, supports the inner wall of the plastic pipe, improving the stability of the pipe's shape during cutting, thereby improving cutting accuracy. The cutter and long blade, along with the cutting groove and long slot, effectively reduce wear on the cutter during use. Because the long blade is installed on the outer wall of the cutter near the support frame and its length is greater than the distance between the end of the plastic pipe that contacts the inner support and the cutting groove, the long blade cuts the plastic pipe, causing the cut plastic pipe to be divided into two semi-circular tubes that automatically fall off the inner support, eliminating the need for subsequent manual pulling out of the inner support.

Description

Technical Field

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

[0002] Plastic pipes are widely used in modern industrial production and daily life. Among them, thin-walled plastic pipes are particularly common in fields with high requirements for pipe performance due to their advantages such as light weight and corrosion resistance. Plastic pipe processing equipment is used in the processing of plastic pipes.

[0003] Currently, when cutting off the ends of thin-walled plastic pipes, plastic pipe end cutting devices are used to cut off the ends of the plastic pipes. It is a type of plastic pipe processing device. The existing technologies commonly used are traditional cutting tools and laser cutting. In the process of traditional cutting tools, it is difficult to accurately control the pressure on the pipe, which can easily cause the outer diameter of the thin-walled plastic pipe to deform inward rapidly when pressure is applied. Although laser cutting can avoid the pressure effect caused by direct contact between the tool and the pipe to a certain extent, its cost and operating cost are relatively high, so traditional cutting tools are still more commonly used.

[0004] However, in actual end-cutting operations, traditional cutting tools struggle to effectively address the issue arising from the hollow structure of thin-walled plastic tubes, where the outer diameter deforms inward under pressure. When cutting, this deformed tube is inevitably severed, causing deformation at the cut. This deformation significantly impacts cutting accuracy, potentially leading to malfunctions and deviations in subsequent assembly and use. Therefore, improvements to existing plastic tube processing equipment are urgently needed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a plastic pipe processing device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a plastic pipe processing device, comprising a support frame and a plastic pipe, wherein an inner support for supporting the plastic pipe is installed on the support frame, and the plastic pipe is sleeved on the inner support;

[0007] The support frame is provided with a cutter and a long blade for cutting plastic pipes on its outer side. The plastic pipe is located between the cutters, and a long blade is installed on the outer wall of the cutter. The minimum diameter of the cutter is smaller than the diameter of the connection between the inner support and the plastic pipe. The inner support is provided with a cutting groove and a long groove corresponding to the cutter and the long blade.

[0008] The support frame has an mounting base on its outer wall, and a bidirectional lead screw is rotatably mounted on the mounting base. A connecting seat that connects to the outer wall of the cutter is threaded onto the bidirectional lead screw. A drive mechanism that is fixedly connected to the bidirectional lead screw is mounted on the mounting base.

[0009] By adopting the above technical solution, the inner support will support the inner wall of the plastic tube, improving the stability of the shape of the plastic tube during cutting, thereby improving the cutting accuracy. Under the action of the cutter and the long blade, and the cutting groove and the long groove, the wear of the cutter during use is effectively reduced. Because the long blade is installed on the outer wall of the cutter near the support frame and its length is greater than the distance between the end of the plastic tube that is in contact with the inner support and the cutting groove, the long blade will cut the plastic tube being cut, causing the cut plastic tube to be divided into two semi-circular tubes, which will automatically fall off the inner support, eliminating the need for subsequent manual operation to pull it out of the inner support.

[0010] Furthermore, the inner bearing has a T-shaped cross-section, and the maximum diameter of the inner bearing is larger than the diameter of the plastic tube.

[0011] By adopting the above technical solution, the outer end of the inner support will support the plastic tube, and its outer wall, which is in contact with the end of the plastic tube, will block the position of the plastic tube.

[0012] Furthermore, the groove is a circular groove design, and the minimum diameter of the groove is smaller than the minimum diameter of the cutter, and the opening position of the groove corresponds to the setting position of the cutter.

[0013] By adopting the above technical solution, the cutter will not collide with the inner support during the cutting process of the upper and lower surfaces of the plastic tube.

[0014] Furthermore, the cutter is a U-shaped cutter, and two sets of cutters are symmetrically arranged at the upper and lower ends of the inner bearing, and connecting seats are bolted to the outer walls of both sets of cutters.

[0015] By adopting the above technical solution, it is ensured that the cutter can successfully cut the plastic tube.

[0016] Furthermore, the long blade is installed on the outer wall of the cutter near the support frame, and the length of the long blade is greater than the distance between the end of the plastic tube that is in contact with the inner support and the cutting groove.

[0017] By adopting the above technical solution, the long blade will divide the cut plastic tube into two semi-circular tubes, so that the cut end of the plastic tube will automatically fall off the inner support.

[0018] Furthermore, two sets of mounting seats are symmetrically installed on the outer wall of the support frame. Two sets of mounting seats are respectively equipped with a bidirectional lead screw and a slide rod, and the slide rod is slidably connected to the connecting seat on the other side of the cutter.

[0019] By adopting the above technical solution, it is ensured that the connecting seat will drive the cutter to slide when the bidirectional lead screw rotates.

[0020] Furthermore, positioning blocks are installed on both outer walls of the cutter, and positioning grooves corresponding to the positioning blocks are opened on the outer wall of the connecting seat. Both the positioning blocks and the positioning grooves have rectangular cross-sections.

[0021] By adopting the above technical solution, the positioning block and the positioning groove will restrict each other when the cutter is in use, thereby ensuring the fixity of the cutter angle.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention features an inner support that supports the inner wall of the plastic tube, improving the stability of the tube's shape during cutting and thus enhancing cutting accuracy. The combination of the cutting blade and the long blade, along with the cutting groove and the long groove, effectively reduces wear on the cutting blade. Because the long blade is mounted on the outer wall of the cutting blade near the support frame and its length exceeds the distance between the end of the plastic tube that contacts the inner support and the cutting groove, the long blade cuts the plastic tube, causing it to split into two semi-circular sections that automatically fall off the inner support, eliminating the need for manual removal.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] A plastic pipe processing device, such as Figure 1 - Figure 5 As shown, it includes a support frame 1 and a plastic tube 2;

[0033] In this embodiment, the support frame 1 is equipped with an inner support 3 for supporting the plastic tube 2. When the plastic tube 2 needs to be cut, the plastic tube 2 is placed on the inner support 3. The inner support 3 will support the inner wall of the plastic tube 2, thereby improving the stability of the shape of the plastic tube 2 during cutting and improving the cutting accuracy.

[0034] In this embodiment, the inner support 3 has a T-shaped cross-section. The diameter of its end near the plastic tube 2 corresponds to the inner diameter of the plastic tube 2, and the maximum diameter of the inner support 3 is greater than the diameter of the plastic tube 2. This allows the outer end of the plastic tube 2 to support the plastic tube 2 after it is fitted onto the inner support 3, and the outer wall of the inner support 3 that is in contact with the end of the plastic tube 2 to shield the position of the plastic tube 2, ensuring the stability of the position of the plastic tube 2 after installation. At the same time, the corners of the inner support 3 are designed with bevels, which effectively reduces the difficulty of fitting the plastic tube 2 onto the inner support 3.

[0035] In this embodiment, the support frame 1 is provided with a cutter 4 and a long knife 5 for cutting plastic tube 2 on its outer side;

[0036] The plastic tube 2 is located between the cutters 4, so that the cutters 4 will cut the plastic tube 2 when they slide. At the same time, a long blade 5 is installed on the outer wall of the cutter 4. Since the minimum diameter of the cutter 4 is smaller than the diameter of the connection between the inner support 3 and the plastic tube 2, it is ensured that the cutter 4 can smoothly cut the plastic tube 2 after sliding. It is also ensured that the cutter 4 can smoothly cut the plastic tube 2. Since the inner support 3 has a cutting groove 31 and a long groove 32 corresponding to the cutter 4 and the long blade 5, it is ensured that the cutter 4 and the long blade 5 will not directly contact the inner support 3 during the process of cutting the plastic tube 2, thus reducing the damage to the cutter 4.

[0037] For example, a mounting base 71 is also installed on the outer wall of the support frame 1, and a bidirectional lead screw 7 is rotatably mounted on the mounting base 71. A connecting seat 6 connected to the outer wall of the cutter 4 is threaded onto the bidirectional lead screw 7. When the bidirectional lead screw 7 rotates, the connecting seat 6 will start to drive the cutter 4 to slide under the action of the lead screw principle, ensuring that the cutter 4 can smoothly obtain the sliding power. A drive mechanism fixedly connected to the bidirectional lead screw 7 is installed on the mounting base 71 to drive the bidirectional lead screw 7 to rotate.

[0038] Please see Figure 1 - Figure 5 In this embodiment, the cutter 4 is a U-shaped cutter, and two sets of cutters 4 are symmetrically arranged at the upper and lower ends of the inner support 3. Because the distance between the ends of the cutters 4 is smaller than the diameter of the inner support 3, during the lifting process, one set of cutters 4 will cut one of the upper and lower surfaces of the plastic tube 2, ensuring that the cutter 4 can smoothly cut the plastic tube 2. In addition, since the outer walls of the two sets of cutters 4 are bolted with connecting seats 6, the stability of the two sets of cutters 4 during operation can be ensured, and the two sets of cutters 4 are connected to each other through the connecting seats 6.

[0039] For example, because the minimum diameter of the groove 31 is smaller than the minimum diameter of the cutter 4, and because the opening position of the groove 31 corresponds to the setting position of the cutter 4, the cutter 4 will not directly contact the inner support 3 during the lifting and lowering process, thereby reducing the wear of the cutter 4 during use. At the same time, because the groove 31 is a circular groove design, the cutter 4 will not collide with the inner support 3 during the cutting of the upper and lower surfaces of the plastic tube 2.

[0040] Please see Figure 3 - Figure 5 When the cutter 4 rises and falls, it will drive the long cutter 5 to move synchronously. Because the long cutter 5 is installed on the outer wall of the cutter 4 near the support frame 1, and because the length of the long cutter 5 is greater than the distance between the end of the plastic tube 2 that is in contact with the inner support 3 and the cutting groove 31, the long cutter 5 will cut the plastic tube 2 during this process, causing the cut plastic tube 2 to be divided into two semi-circular tubes. At this time, the two semi-circular tubes will lose their mutual restraint and automatically fall off the inner support 3, saving the subsequent manual operation of pulling them out of the inner support 3.

[0041] Please see Figure 1 - Figure 3 In this embodiment, two sets of mounting bases 71 are symmetrically installed on the outer wall of the support frame 1. At the same time, a bidirectional lead screw 7 and a slide rod 72 are respectively installed on the two sets of mounting bases 71. The slide rod 72 is slidably connected to the connecting seat 6 on the other side of the cutter 4, so that the connecting seats 6 on both sides of the cutter 4 are restricted, so that the cutter 4 and the connecting seat 6 cannot change the angle, thereby ensuring that the bidirectional lead screw 7 will cause the connecting seat 6 to drive the cutter 4 to slide when it rotates.

[0042] For example, bolts and positioning blocks 41 are installed on both outer walls of the cutter 4. At the same time, a nut corresponding to the bolt is rotatably installed on one outer wall of the connecting seat 6, and a positioning groove corresponding to the positioning block 41 is opened on the other outer wall of the connecting seat 6. When it is necessary to connect the cutter 4 to the connecting seat 6, the cutter 4 is connected to the connecting seat 6 by bolts and nuts, so that the positioning block 41 will enter the positioning groove. Since the positioning block 41 and the positioning groove are both rectangular in cross section, the positioning block 41 and the positioning groove will restrict each other when the cutter 4 is in use, so as to ensure the fixation of the angle of the cutter 4.

[0043] In some examples, the drive component is a motor 8 fixedly mounted on the mounting base 71. Because the end of the motor 8 is fixedly connected to the end of the bidirectional lead screw 7, the motor 8 will smoothly rotate the bidirectional lead screw 7 after starting.

[0044] It should be noted that the number of revolutions of motor 8 is the same each time it starts. After starting, it will first make the cutter 4 move downward, then make the cutter 4 move upward under the action of the bidirectional lead screw 7, and finally move downward again to return to a state where it does not interfere with the plastic tube 2. At this time, motor 8 will stop automatically.

[0045] The working principle of this utility model is as follows: When using this device, first push the plastic tube 2 onto the inner support 3 so that the end of the plastic tube 2 is in contact with the outer wall of the inner support 3. At this time, the end of the inner support 3 will support the inner wall of the plastic tube 2, ensuring the stability of the cutting position of the plastic tube 2 during the subsequent cutting process.

[0046] Next, the drive assembly is activated, causing the bidirectional lead screw 7 to rotate. This causes the connecting seat 6 to drive the cutter 4 downwards under the influence of the lead screw. At this time, the cutter 4 drives the long blade 5 downwards to cut the end of the plastic tube 2. Because the inner wall of the plastic tube 2 is supported by the inner bearing 3, the probability of deformation of the plastic tube 2 during cutting is greatly reduced. The cutter 4 will make a horizontal cut on the plastic tube 2, and the long blade 5 will make a vertical cut on the cut-off part of the plastic tube 2. As the bidirectional lead screw 7 continues to rotate, the connecting seat 6 begins to drive the cutter 4 upwards, causing another set of cutters 4 to begin cutting the bottom of the plastic tube 2. At the same time, the long blade 5 cuts the bottom of the cut-off part of the plastic tube 2, causing the cut-off plastic tube 2 to be cut into two halves and fall off automatically, thus achieving automatic removal of waste material while cutting the plastic tube 2.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
