Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a plastic pipe cutting device. Background Technology

[0002] Plastic pipes are high-tech composite chemical building materials. Compared with traditional metal pipes, they offer advantages such as energy and material conservation, environmental friendliness, corrosion resistance, light weight, easy molding, easy processing, and long service life, making them widely used in various fields. In the medical device field, plastic pipes are typically precision catheters. These pipes are generally small in size, thin in wall thickness, and soft in material, with high dimensional accuracy requirements, especially for catheters or microcatheters used in intra-human intervention. Therefore, the cutting requirements are high; the cut end must be smooth, clean, free of burrs, sharp corners, and deformation. Currently, medical-grade plastic pipes are usually cut manually, which easily leads to problems such as beveled cuts due to angle deviations or deformation caused by compression of the pipe body, requiring rework and increasing labor costs. Existing equipment for cutting medical-grade plastic pipes is generally single-station cutting, resulting in low production efficiency. Furthermore, cutting debris is generally not collected during the cutting operation, affecting the cleanliness of the workstation and posing safety hazards. Therefore, it is necessary to design a device that can cut multiple tubes at a fixed distance simultaneously and collect the shavings in a timely manner to achieve high-efficiency and high-quality cutting of medical-grade plastic tubes. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the existing technology by providing a more efficient and convenient plastic pipe cutting device. When using this device to cut plastic pipes, it not only prevents pipe deformation and improves cutting accuracy and cut quality, but also allows for timely disposal of waste materials, saving manpower and resources and increasing production efficiency.

[0004] To achieve the above objectives, this utility model provides a plastic pipe cutting device, including a base plate, a guide rail, a tray, a guide tube groove, a cylinder, a cylinder support, a tool fixing plate, and a guide rail support. The cylinder support and guide rail support are fixed to the base plate. A guide rail is provided on the guide rail support. The guide tube groove is set on the tray connected to the guide rail and can slide freely on the guide rail. The guide tube groove has multiple workstations and can hold multiple guide tubes to achieve multi-pipe cutting. The cylinder is assembled on the cylinder support with an inclined angle and connected to the tool fixing plate. At the same time, the tool fixing plate is connected to the slider and the slider guide rail and fixed on the slider guide rail support with an inclined angle. The base plate is provided with multiple replaceable guide tube grooves of different specifications. The shorter guide tube grooves are assembled on the tray with gaskets to cut pipes of different specifications.

[0005] Preferably, channels of different sizes can be provided on the conduit groove to fix plastic pipes of different diameters, so as to realize the simultaneous cutting of plastic pipes of multiple diameters.

[0006] Furthermore, the tray is equipped with a motor, which can control the movement of the guide groove on the tray, sending the guide to the corresponding position below the cutter fixing plate for cutting, thus realizing the automation of the cutting of the entire device.

[0007] Preferably, a cutting groove is also provided, which restricts the movement of the cutting tool and prevents its position from shifting. A waste collection box is provided after the cutting groove. The waste collection box is equipped with a crushing component, which can directly collect and reprocess the waste after the pipe cutting is completed.

[0008] This invention relates to a device that can simultaneously assemble multiple pipes, enabling simultaneous, spaced-distance cutting of multiple pipes and improving work efficiency. The cutting tool employs a sliding cutting mode when in contact with the pipe, which buffers the compressive force generated during contact, reducing compressive strength and preventing pipe deformation that could lead to malfunction. The cutting tool is confined within the cutting groove during cutting, ensuring cutting precision. Containing multiple stations, it can automatically cut plastic pipes of various diameters at a fixed distance, achieving high cutting accuracy and efficiency. Furthermore, the device can collect chips promptly, improving chip handling efficiency.

[0009] This invention develops a more efficient and convenient plastic pipe cutting device.

[0010] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] This invention provides a multi-station plastic pipe cutting device capable of collecting waste materials. By setting multiple channels on the feeding base plate, multiple pipes can be fed and cut simultaneously. Depending on the application, channels of different diameters can be set on the base plate to fix plastic pipes of different diameters, solving the problem that most existing devices cannot cut multi-diameter plastic pipes. Furthermore, the feeding base plate can be moved on a tray by a motor to achieve automatic, fixed-distance cutting of the pipes. Because the blade is confined within the cutting groove, high cutting accuracy is achieved. The connection and support between the blade fixing plate, guide rail, and cylinder on the device adopts a wedge design. The guide rail moves at an angle, converting the cylinder's thrust into an oblique thrust. This decomposes the cylinder's strong driving force in both the horizontal and vertical directions, controlling the cutting between the blade and the pipe as a sliding cut, reducing the extrusive force generated in the vertical direction when the blade contacts the pipe. This prevents pipe deformation and buffers the strong impact force of the cylinder, avoiding damage to the device. In addition, a waste collection box is installed on the device. After cutting, the waste will automatically fall into the box, which can prevent waste from falling onto the workstation and affecting the cleanliness and aesthetics of the workstation. For pipes with safety hazards (such as sharp pipes) or pipes that need to be recycled, a crushing component can be installed in the collection box to crush the waste in a timely manner, saving additional processing steps.

[0018] To make the technical problem to be solved by this utility model, the proposed technical solution, and its beneficial effects clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. The scope of protection of the present utility model is not limited by the specific embodiments.

At the same time, the tool fixing plate 18 is connected to the slider 110 and the slider guide rail 19 and fixed on the slider guide rail support 111 with a tilt angle. This wedge design allows the cylinder to drive at an angle, controlling the tool to cut the tube in a sliding cutting mode to prevent the tube from deforming. The cutting tool is confined within the tool groove 112 during movement, which prevents the tool from shifting position and improves cutting accuracy. After cutting, the waste chips can automatically fall into the waste chip collection box 113 behind the tool groove 112, preventing them from falling randomly onto the workstation and affecting the cutting operation.

[0020] The following is the second embodiment, see details. Figure 3 Multiple replaceable conduit grooves of different specifications are provided on the base plate 11. Shorter conduit grooves 23 can be mounted on the tray 14 using gaskets 22 to cut pipes of different specifications. Channels of different sizes can be set on the same conduit groove 15 to fix plastic pipes of different diameters, enabling simultaneous cutting of plastic pipes of multiple diameters. A motor 21 is provided on the left side of the tray 14 to control the movement of the conduit grooves 15 on the tray 14, sending the conduit to the corresponding position below the cutter fixing plate 18 for cutting, thus automating the cutting process of the entire device.
