Description

Technical Field

[0001] This application pertains to plastic pipe cutting equipment, and more particularly to a plastic pipe cutting machine. Background Technology

[0002] Plastic products are a general term for household and industrial goods made primarily from plastics. This includes products manufactured using processes such as injection molding and thermoforming. Plastics are a type of synthetic polymer material with malleability. Currently, plastic products come in various shapes and styles. Because plastic pipes are generally quite long, they sometimes need to be cut for use. The common practice is to first fix the plastic pipe in place and then process it using a cutting machine.

[0003] Patent CN107322670B discloses a plastic pipe cutting machine, including a base. The bottom of the base has four rectangular legs. The upper end of the base has two horizontally distributed fixing blocks. Each fixing block has a clamping device at its upper end. The clamping device includes a frame. Both ends of the upper and lower inner sidewalls of the frame are provided with limiting slide rails. Both the upper and lower inner sidewalls of the frame are provided with spring groups. The end of the spring group away from the inner sidewall is provided with an arc-shaped limiting plate. Each limiting slide rail is provided with a sliding support rod. The end of the sliding support rod away from the limiting slide rail is rotatably connected to the arc-shaped limiting plate. The upper side of the base has two L-shaped brackets. The ends of the two L-shaped brackets are connected to a first rubber limiting block.

[0004] The aforementioned patent uses a clamping device to fix the plastic pipe. It relies on the cooperation of the frame, limiting slide rail, spring assembly, arc-shaped limiting plate, and sliding support rod to achieve the fixing effect. Although it can achieve the fixing effect, the fixing effect is not good and it is easy to shift or shake, resulting in a decrease in cutting accuracy. It needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a plastic pipe cutting machine that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a plastic pipe cutting machine, including a frame, a worktable mounted on the frame, and a cutting device mounted on the worktable, characterized in that: it further includes a clamping mechanism mounted on the worktable for clamping the plastic pipe, the clamping mechanism comprising: A support base is set on the workbench, with a through hole in the center for a plastic tube to pass through; A support structure, mounted on a support base, is used to support the plastic tube; A clamping structure is provided on the support base; The clamping structure is provided in multiple parts and is evenly distributed along the axis of the through hole.

[0007] The aforementioned plastic pipe cutting machine features a support base mounted on a worktable. A central through-hole provides a precise path for the plastic pipe, ensuring accurate positioning before cutting, further stabilizing the pipe, and reducing deformation caused by its own weight or cutting force, thus improving cutting accuracy. The clamping structure is evenly distributed along the axis of the through-hole. Multiple clamping points effectively disperse the lateral force generated during cutting, preventing pipe displacement or wobbling due to excessive force at a single point. The clamping structure design ensures the pipe is firmly fixed during cutting, further enhancing cutting stability and precision. Simultaneously, due to the stable support and firm clamping provided by the clamping mechanism, the cutting device can cut more accurately along the preset path, thereby improving cutting accuracy and finished product quality.

[0008] Furthermore, the support structure includes a support plate disposed on a support base, a telescopic rod disposed on the support plate, and a guide wheel disposed on the telescopic rod, the guide wheel being in contact with the plastic pipe.

[0009] The support plate, serving as the foundation of the support structure, is mounted on the support base, providing a support platform for the telescopic rod and guide wheels. The telescopic rod, mounted on the support plate, is adjustable according to the diameter of the plastic pipe to accommodate different sizes. The guide wheels, installed at the end of the telescopic rod, are in direct contact with the plastic pipe, guiding and supporting it. Through the cooperation of the support plate, telescopic rod, and guide wheels, the plastic pipe is supported and guided, improving its stability during cutting and reducing cutting errors caused by pipe swaying or offset.

[0010] Furthermore: the clamping structure includes: The contact plate contacts the outer wall of the plastic pipe. A driver whose output shaft is connected to the contact plate and is used to drive the contact plate to move; An adjustment structure is mounted on a support base, and a driver is mounted on the adjustment structure. The adjustment structure is used to adjust the position of the driver to accommodate plastic tubes of different diameters.

[0011] The contact plate directly contacts the outer wall of the plastic pipe, applying pressure to fix the pipe in place. It utilizes wear-resistant, low-friction materials to minimize damage to the pipe surface and ensure consistent clamping performance even after prolonged use. The selected material also needs to possess a degree of elasticity to accommodate minor surface irregularities and ensure even distribution of clamping force. The actuator, acting as the power source for the clamping structure, connects its output shaft to the contact plate, driving its movement to clamp and release the pipe. This actuator can be a cylinder. An adjustment mechanism, mounted on the support base, allows for adjusting the actuator's position to accommodate plastic pipes of different diameters. This adjustment mechanism enables users to easily adjust the positions of the actuator and contact plate to fit different pipe sizes, improving the equipment's versatility and flexibility, and meeting various cutting needs without requiring replacement of the clamping components.

[0012] Furthermore, the adjustment structure includes: The positioning seat is mounted on the support seat; A servo motor is mounted on a positioning seat, and a threaded rod is provided on its output shaft. A movable seat is mounted on the threaded rod and threadedly connected to the threaded rod. The driver is mounted on a movable base, and the movable base is moved by a servo motor, which in turn moves the driver.

[0013] The positioning seat, serving as the foundation of the adjustment structure, provides a support platform for the servo motor and the threaded rod. The servo motor, acting as the power source for the adjustment structure, has a threaded rod on its output shaft. Rotating the threaded rod drives the moving seat. The threaded rod and the moving seat are connected by a thread, converting the rotational motion of the servo motor into the linear motion of the moving seat. This not only enables precise adjustment of the moving seat but also provides a degree of self-locking, ensuring the moving seat remains stable even in the event of a power outage.

[0014] The adjustment structure, through the cooperation of the positioning seat, servo motor, threaded rod and moving seat, enables precise adjustment of the driver. Users can easily adjust the position of the driver and contact plate by controlling the rotation direction and speed of the servo motor to adapt to pipes of different diameters.

[0015] Furthermore, drivers are provided on both sides of the movable seat, and the two drivers are symmetrical about the threaded rod.

[0016] With two actuators operating simultaneously, a greater clamping force can be applied to the plastic pipe, ensuring its stability during cutting. The dual-actuator design also enhances the reliability of the clamping mechanism; even if one actuator fails, the other can continue operating to hold the pipe in place. Furthermore, the symmetrical distribution of the two actuators about the threaded rod ensures a uniform distribution of clamping force, preventing deformation or displacement of the pipe caused by unilateral clamping. This improves cutting accuracy and ensures a smooth, burr-free cut.

[0017] Furthermore, the end of the contact plate that contacts the plastic tube is arc-shaped, and the end away from the plastic tube is connected to the output shafts of the two drivers.

[0018] The curved contact surface better conforms to the outer wall of the plastic pipe, ensuring a uniform distribution of clamping force. This reduces the risk of pipe deformation or damage caused by uneven clamping force, increases the contact area, and improves the support and stability of the clamping mechanism, effectively maintaining the pipe's fixed position. Furthermore, by adjusting the position of the actuator, clamping and fixing pipes of different sizes can be easily achieved, improving the equipment's flexibility and applicability, enabling the cutting machine to handle various pipe specifications more efficiently.

[0019] The end of the contact plate furthest from the plastic pipe is connected to the output shafts of the two drivers, ensuring a stable transmission of clamping force. The two drivers work simultaneously, applying the clamping force evenly to the pipe through the contact plate, thus achieving reliable fixation of the pipe.

[0020] The beneficial effects of this application are: 1. The clamping structure is evenly distributed along the axis of the through hole. The setting of multiple clamping points effectively disperses the lateral force generated during cutting, avoiding the pipe from shifting or shaking due to excessive force at a single point. The design of the clamping structure ensures the pipe is firmly fixed during the cutting process, further improving the stability and accuracy of cutting. 2. Through the cooperation of support plate, telescopic rod and guide wheel, the plastic pipe is supported and guided, which not only improves the stability of the pipe during the cutting process, but also reduces the cutting error caused by pipe shaking or deviation. 3. By setting an adjustment structure, users can easily adjust the position of the driver and contact plate to adapt to pipes of different sizes, thereby improving the versatility and flexibility of the equipment, and meeting a variety of cutting needs without replacing the clamping parts.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The plastic pipe cutting machine provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0026] Example 1: like Figures 1 to 3 As shown, this application provides a plastic pipe cutting machine, including a frame 100, a worktable 110 disposed on the frame 100, and a cutting device 120 disposed on the worktable 110. The machine is characterized by further including a clamping mechanism 200 disposed on the worktable 110 and used to clamp the plastic pipe. The clamping mechanism 200 includes: The support base 210 is set on the workbench 110, and a through hole 211 for the plastic tube to pass through is provided in the center; The support structure 220 is mounted on the support base 210 and is used to support the plastic tube; The clamping structure 230 is provided on the support base 210; The clamping structure 230 is provided in multiple parts and is evenly distributed along the axis of the through hole 211.

[0027] In some embodiments of this application, such as Figure 1 As shown, in the plastic pipe cutting machine described above, the support base 210 is set on the worktable 110. The through hole 211 in the center of the support base provides a precise path for the plastic pipe, ensuring the accuracy of the pipe's position before cutting, further stabilizing the pipe, and reducing deformation caused by the pipe's own weight or cutting force, thereby improving the cutting accuracy. The clamping structure 230 is evenly distributed along the axis of the through hole 211. The multiple clamping points effectively disperse the lateral force generated during cutting, avoiding the pipe's deviation or shaking due to excessive force at a single point. The design of the clamping structure 230 ensures the pipe is firmly fixed during the cutting process, further improving the stability and accuracy of the cutting. At the same time, due to the stable support and firm clamping provided by the clamping mechanism 200, the cutting device 120 can cut more accurately along the preset path, thereby improving the cutting accuracy and product quality.

[0028] Example 2: This application provides a plastic pipe cutting machine, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0029] like Figure 3 As shown, the support structure 220 includes a support plate 221 disposed on the support base 210, a telescopic rod 222 disposed on the support plate 221, and a guide wheel 223 disposed on the telescopic rod 222. The guide wheel 223 is in contact with the plastic pipe.

[0030] In this embodiment, the support plate 221 serves as the foundation of the support structure 220, mounted on the support base 210, providing a support platform for the telescopic rod 222 and the guide wheel 223. The telescopic rod 222, mounted on the support plate 221, can be adjusted according to the diameter of the plastic pipe to accommodate pipes of different sizes. The guide wheel 223, mounted at the end of the telescopic rod 222, directly contacts the plastic pipe, serving to guide and support the pipe. Through the cooperation of the support plate 221, the telescopic rod 222, and the guide wheel 223, support and guidance of the plastic pipe are achieved, which not only improves the stability of the pipe during the cutting process but also reduces cutting errors caused by pipe swaying or deviation.

[0031] Example 3: This application provides a plastic pipe cutting machine, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0032] like Figure 2 and Figure 3As shown, the clamping structure 230 includes: Contact plate 231 contacts the outer wall of the plastic pipe; The driver 232 has its output shaft connected to the contact plate 231 and is used to drive the contact plate 231 to move. An adjustment structure 300 is mounted on a support base 210, and a driver 232 is mounted on the adjustment structure 300. The adjustment structure 300 is used to adjust the position of the driver 232 to accommodate plastic tubes of different diameters.

[0033] In this embodiment, the contact plate 231 directly contacts the outer wall of the plastic pipe, applying pressure to fix the pipe. A wear-resistant, low-friction material is used to reduce damage to the pipe surface and ensure good clamping performance even after prolonged use. The material also needs to have a certain degree of elasticity to accommodate minor unevenness on the pipe surface, ensuring uniform distribution of clamping force. The actuator 232, serving as the power source for the clamping structure 230, has its output shaft connected to the contact plate 231, driving the contact plate 231 to move, thereby clamping and releasing the pipe. The actuator 232 can be a cylinder. An adjustment structure 300 is mounted on the support base 210 to adjust the position of the actuator 232 to accommodate plastic pipes of different diameters. Through the adjustment structure 300, users can easily adjust the positions of the actuator 232 and the contact plate 231 to accommodate pipes of different sizes, thus improving the versatility and flexibility of the equipment and meeting various cutting needs without replacing the clamping components.

[0034] Example 4: This application provides a plastic pipe cutting machine, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0035] like Figure 2 and Figure 3 As shown, the adjustment structure 300 includes: Positioning seat 310 is mounted on support seat 210; A servo motor 320 is mounted on a positioning seat 310, and a threaded rod 321 is provided on its output shaft; The movable seat 330 is mounted on the threaded rod 321 and threadedly connected to the threaded rod 321. The driver 232 is mounted on the movable base 330 and moves the movable base 330 via the servo motor 320, thereby moving the driver 232.

[0036] In this embodiment, the positioning seat 310 serves as the foundation of the adjustment structure 300, providing a support platform for the servo motor 320 and the threaded rod 321. The servo motor 320, as the power source of the adjustment structure 300, has a threaded rod 321 on its output shaft. Rotating the threaded rod 321 drives the moving seat 330 to move. The threaded rod 321 and the moving seat 330 are connected by a thread. The rotational motion of the thread converts the rotational motion of the servo motor 320 into the linear motion of the moving seat 330, achieving not only precise adjustment of the moving seat 330 but also a certain self-locking function, maintaining the stable position of the moving seat 330 even in the event of a power outage.

[0037] The adjustment structure 300, through the cooperation of the positioning seat 310, servo motor 320, threaded rod 321 and moving seat 330, realizes the precise adjustment of the driver 232. The user can conveniently adjust the position of the driver 232 and the contact plate 231 by controlling the rotation direction and speed of the servo motor 320 to adapt to pipes of different diameters.

[0038] Furthermore, a driver 232 is provided on both sides of the movable seat 330, and the two drivers 232 are symmetrical about the threaded rod 321.

[0039] The simultaneous operation of two actuators 232 allows for the application of greater clamping force to the plastic pipe, ensuring its stability during cutting. Furthermore, the dual-actuator design enhances the reliability of the clamping mechanism 200; even if one actuator 232 fails, the other can continue operating to maintain the pipe's fixation. Additionally, the symmetrical distribution of the two actuators about the threaded rod 321 ensures a uniform distribution of clamping force, preventing pipe deformation or displacement caused by unilateral clamping, thereby improving cutting accuracy and ensuring a smooth, burr-free cut surface.

[0040] Example 5: This application provides a plastic pipe cutting machine, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0041] like Figure 2 and Figure 3 As shown, the end of the contact plate 231 that contacts the plastic tube is arc-shaped, and the end away from the plastic tube is connected to the output shaft of the two drivers 232.

[0042] In this embodiment, the arc-shaped contact surface can better conform to the outer wall of the plastic pipe, ensuring a uniform distribution of clamping force. This reduces the risk of pipe deformation or damage caused by uneven clamping force, and also increases the contact area, improving the support and stability of the clamping mechanism 200 for the pipe, effectively maintaining the pipe's fixed position. Simultaneously, by adjusting the position of the driver 232, clamping and fixing pipes of different sizes can be easily achieved, improving the equipment's flexibility and applicability, enabling the cutting machine to process various pipe specifications more efficiently.

[0043] The end of the contact plate 231 away from the plastic pipe is connected to the output shaft of the two drivers 232, ensuring the stable transmission of clamping force. The two drivers 232 work simultaneously, and the clamping force is evenly applied to the pipe through the contact plate 231, thus achieving reliable fixation of the pipe.
