Description

Technical Field

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

[0002] PVC pipes, or rigid polyvinyl chloride pipes, are made by hot-pressing polyvinyl chloride resin with stabilizers, lubricants, and other additives. They were among the earliest plastic pipe materials developed and applied. PVC pipes are highly corrosion-resistant, easy to bond, inexpensive, and durable. They are currently widely used in municipal, construction, water supply and drainage, and chemical industries for transporting heating fluids, cooling fluids, food products, ultrapure liquids, slurries, gases, and compressed air.

[0003] When manufacturing existing PVC pipes, some pipes need to be cut into two C-shaped sections at the end, depending on the working conditions. Due to the special cross-sectional shape, the pipes are often manually rotated and squeezed to fix them before cutting. Manually rotating the pipes introduces certain rotational errors, resulting in low efficiency and inconvenience in the manufacturing process. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for PVC pipe processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for PVC pipe processing, comprising a support base, a cutting machine fixedly mounted on one side of the top of the support base, symmetrically arranged transmission shafts rotatably connected to the support base, rubber rollers fixedly connected to each transmission shaft, gears fixedly connected to one end of each transmission shaft, an electric telescopic rod fixedly mounted on the support base corresponding to the gear, a rack fixedly connected to the output end of the electric telescopic rod, a transmission disc fixedly connected to the end of each transmission shaft away from the gear, an extrusion shaft fixedly connected to one side of the transmission disc away from the center, a transmission frame sleeved on each extrusion shaft, a limit groove opened on the support base corresponding to the transmission frame, the transmission frame slidingly connected to the limit groove, a transmission rod fixedly connected to the top of each transmission frame, a bracket fixedly connected to the top of two transmission rods, an extrusion plate fixedly connected to the bottom of the bracket, and a rubber layer fixedly connected to the bottom of the extrusion plate.

[0006] Preferably, the support base has a trapezoidal structure design, and the corners of the support base are rounded.

[0007] Preferably, the rack is provided correspondingly to the two gears, and the rack is meshed with the gears.

[0008] Preferably, the transmission frame is a rectangular frame structure, and the extrusion shaft is slidably connected to the transmission frame.

[0009] Preferably, the extrusion plate and the rubber layer are both designed in a semi-circular shape.

[0010] Compared with the prior art, the advantages of this utility model are: the pipe can be rotated 180 degrees simply by starting the electric telescopic rod, reducing the rotation error caused by manually rotating the pipe, while clamping and fixing it, improving the cutting quality and efficiency of the pipe, and making it more convenient to use.

[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. 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.

[0017] Please see Figure 1-4This utility model provides a technical solution: a cutting device for PVC pipe processing, including a support base 1, a cutting machine 2 fixedly installed on one side of the top of the support base 1, a symmetrically arranged transmission shaft 3 rotatably connected to the support base 1, a rubber roller 4 fixedly connected to each of the transmission shafts 3, a gear 5 fixedly connected to one end of each of the transmission shafts 3, an electric telescopic rod 6 fixedly installed on the support base 1 corresponding to the gear 5, a rack 7 fixedly connected to the output end of the electric telescopic rod 6, a transmission disc 8 fixedly connected to the end of each of the transmission shafts 3 away from the gear 5, an extrusion shaft 9 fixedly connected to one side of each of the transmission discs 8 away from the center, a transmission frame 10 sleeved on each of the extrusion shafts 9, a limit groove 11 opened on the support base 1 corresponding to the transmission frame 10, the transmission frame 10 slidingly connected to the limit groove 11, a transmission rod 12 fixedly connected to the top of each of the transmission frames 10, a bracket 13 fixedly connected to the top of the two transmission rods 12, an extrusion plate 14 fixedly connected to the bottom of the bracket 13, and a rubber layer 15 fixedly connected to the bottom of the extrusion plate 14.

[0018] The support base 1 has a trapezoidal structure design with rounded corners for easy use and to prevent scratching of operators. The rack 7 is correspondingly set with two gears 5, and the meshing connection between the rack 7 and the gears 5 facilitates the rack 7 to compress and drive the two gears 5, making the two gears 5 rotate in the same direction. The transmission frame 10 has a rectangular frame structure design, and the extrusion shaft 9 is slidably connected to the transmission frame 10 to facilitate the extrusion shaft to compress and drive the transmission frame 10. The extrusion plate 14 has a semi-circular structure design, and the rubber layer 15 has a semi-circular structure design, which facilitates the extrusion plate 14 to compress and fix the PVC pipe through the rubber layer 15.

[0019] Specifically, when using this utility model, the pipe is placed between the extrusion plate 14 and the two rubber rollers 4. The cutting machine 2 is started. After the cutting machine 2 makes an initial cut to one end of the pipe, the electric telescopic rod 6 is started. The electric telescopic rod 6 drives the rack 7 to move. The moving rack 7 performs extrusion transmission on the two gears 5. The extruded gears 5 drive the transmission shaft 3 to rotate. The transmission shaft 3 drives the rubber rollers 4 to rotate. The rotating rubber rollers 4 simultaneously drive the transmission disc 8 to rotate. The transmission disc 8 drives the extrusion shaft 9 to rotate. The rotating extrusion shaft 9 extrudes the transmission frame 10. The extruded transmission frame 10 moves upward along the limiting groove 11. The transmission frame 10 drives the transmission rod 12 to move upward. The moving transmission rod 12 drives the support 13 to move upward. The upward-moving support 13 drives the extrusion plate 14 and the rubber layer 15 to move upward. The rubber roller 4 drives the pipe to rotate while simultaneously causing the extrusion plate 14 to stop extruding the pipe. When the rubber roller 4 rotates 180 degrees and the pipe completes its flip, the transmission disc 8 drives the extrusion shaft 9 to rotate 180 degrees. The extrusion shaft 9 then extrudes the transmission frame 10 again. The extruded transmission frame 10, through the transmission rod 12, support 13, and extrusion plate 14, extrudes and fixes the pipe again. At this point, the pipe can be cut to complete the processing.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
