[0001] This utility model relates to the technical field of cutting devices, and in particular to a PVC plastic hose cutting device. Background Technology

[0002] Flexible PVC pipes are made by adding a large amount of plasticizer, a certain amount of stabilizer, and other additives to PVC resin, followed by extrusion molding. Flexible PVC pipes possess excellent chemical stability, superior electrical insulation properties, and good flexibility and colorability. This type of pipe is commonly used to replace rubber hoses for transporting liquids and corrosive media, and is also used as cable conduit and wire insulation. During production and sales, a cutting device is needed to cut the pipes and roll them into finished flexible hose coils of different lengths. Existing technology announcement number CN215471494U discloses a PVC plastic pipe cutting device, including an operating table and a cutting machine fixedly installed at the bottom of the operating table. The operating table has a smooth through-slot that penetrates the table, and the cutting machine blade passes perpendicularly through the smooth through-slot. The top surface of the operating table has three long slots, two of which are parallel to the length direction of the smooth through-slot and are located on both sides of the smooth through-slot. Threaded rods are rotatably installed in each of the long slots. However, this device is bulky, inconvenient to move, lacks flexibility, and is not suitable for use at sales locations, resulting in poor practicality. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a PVC plastic hose cutting device with a flat cutting surface, compact size, easy handling, high flexibility, and improved practicality.

[0004] This utility model discloses a PVC plastic hose cutting device, comprising a base, a vertical plate, a mounting box, a cutting component, a clamping mechanism, and a fixing component. The vertical plate is mounted on the rear side of the top center of the base, and the mounting box is fixedly mounted on the top of the vertical plate. The cutting component is installed inside the mounting box, and clamping mechanisms are installed on the left and right side walls of the mounting box. Fixing components are installed on the left and right sides of the vertical plate in cooperation with the clamping mechanisms. The PVC hose is placed on the top of the base, and the clamping mechanism clamps and flattens the two sides of the PVC hose at the cutting section, ensuring a flat cut surface. The fixing components limit and fix the position of the clamping mechanism. The cutting component then cuts the PVC hose. The device is compact, easy to transport, highly flexible, and improves practicality.

[0005] Preferably, the cutting assembly includes an electric telescopic rod, a cutting blade, a controller, and mounting components. The electric telescopic rod is fixedly installed on the top of the mounting box. The cutting blade is mounted on the bottom of the electric telescopic rod via the mounting components, with its bottom penetrating the bottom of the mounting box and located above the base. The controller is installed on the front side wall of the mounting box. During cutting, the controller controls the extension of the electric telescopic rod, pushing the cutting blade downward to cut the PVC hose. The cutting speed is fast, and the cut surface is smooth. The telescopic end of the electric telescopic rod pushes the mounting plate downward, and the mounting plate drives the limit slider to slide within the limit groove, ensuring stability during up and down movement, preventing the cutting blade from shaking, and ensuring cutting quality.

[0006] Preferably, the mounting components include two guide strips, a mounting plate, two limiting sliders, and a mounting base. The two guide strips are fixedly installed on the front and rear sides inside the mounting box, and limiting grooves are formed in the guide strips. Limiting sliders are fixedly installed at both ends of the mounting plate, and the limiting sliders are slidably installed in the limiting grooves. The top of the cutting blade is detachably connected to the bottom of the mounting plate. A mounting base is installed in the middle of the mounting plate, and the bottom telescopic end of the electric telescopic rod is fixedly connected to the top of the mounting base. The telescopic end of the electric telescopic rod pushes the mounting plate downward, and the mounting plate drives the limiting sliders to slide in the limiting grooves, which can ensure the stability during up and down movement, prevent the cutting blade from shaking, and ensure the cutting quality.

[0007] Preferably, the clamping mechanism includes two support plates, two sets of clamping rods, two clamping blocks, two pressing blocks, and two sets of springs. The two support plates are fixedly installed on the lower ends of the left and right side walls of the mounting box. Two clamping rods are slidably installed on the support plates. A clamping block is fixedly installed at the bottom of the clamping rod, and a pressing block is installed at the top of the clamping rod. A spring is fitted on the upper part of the clamping rod. The bottom of the spring is connected to the top of the support plate, and the top of the spring is connected to the bottom of the pressing block. Pressing the pressing block pushes the clamping rod to slide on the support plate, causing the clamping block to move downward, clamping and flattening both sides of the PVC hose cutting part, making the PVC hose stable and preventing it from rotating, and ensuring that the cut surface is flush.

[0008] Preferably, the fixing assembly includes two vertical frames, two racks, two fixing plates, two push rods, two limiting teeth, two push springs, and two pull plates. The two vertical frames are respectively fixedly installed on the rear side wall of the clamping block. A rack is installed on the rear side wall of the vertical frame. The fixing plates are fixedly installed on the left and right side walls of the vertical plate. The push rods are slidably installed on the fixing plates. A limiting tooth is installed at the front end of the push rod, and a pull plate is installed at the rear end of the push rod. The push spring is fitted on the rear end of the push rod. The front end of the push spring is connected to the rear side wall of the fixing plate, and the rear end of the push spring is connected to the pull plate. Pulling the pull plate causes the push rod to slide on the fixing plate and stretches the push spring, causing the limiting teeth to move backward. After pressing the pressing block and pushing the clamping block to move downward into place, the pull plate is released, allowing the push spring to return to its original state, causing the limiting teeth to engage with the racks and limit the clamping block. After cutting, pulling the pull plate again allows the spring to push the clamping block upward, releasing the clamping of the PVC hose.

[0009] Preferably, it also includes two support plates, which are fixedly installed on the top left and right ends of the base. A cutting groove is opened on the top of the base between the two support plates, and a V-shaped positioning groove is opened on the top of the support plate. The bottom of the clamping block is set to match the shape of the V-shaped positioning groove. The PVC hose is placed in the V-shaped positioning groove on the top of the support plate to prevent the PVC hose from rolling. The cutting groove in the middle can ensure the cutting depth and can be cut in one go.

[0010] Preferably, it also includes multiple adjustable support legs and an inspection cover. The multiple adjustable support legs are respectively installed at the four corners of the bottom of the base, and the inspection cover is installed on the left side wall of the mounting box and fixed with screws. The multiple adjustable support legs support the bottom of the base, making it easy to adjust the base to be level. Removing the inspection cover allows for the inspection of the components inside the mounting box, making it convenient to use.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the PVC hose is placed on the top of the base, and the clamping mechanism clamps and flattens the two sides of the PVC hose cutting part to ensure the flatness of the cutting surface. The clamping mechanism is fixed by the fixing component, and the PVC hose is cut by the cutting component. The equipment is compact, easy to carry, highly flexible, and improves its practicality.

The rear end of the push spring 22 is connected to the pull plate 23.

[0020] During cutting, the controller 11 controls the extension of the electric telescopic rod 4, pushing the cutting blade 5 downward to cut the PVC hose. The cutting speed is fast and the cut surface is flat. Pressing the pressing block 15 pushes the clamping rod 13 to slide on the support plate 12, causing the clamping block 14 to move downward, clamping and flattening both sides of the PVC hose at the cutting part, making the PVC hose stable and preventing it from rotating, ensuring that the cut surface is flush. Pulling the pull plate 23 drives the push rod 20 to slide on the fixed plate 19, and stretches the push spring 22, causing the limit tooth block 21 to move backward. After pressing the pressing block 15 to push the clamping block 14 downward to the position, the pull plate 23 is released, allowing the push spring 22 to return to its original state, causing the limit tooth block 21 to mesh with the straight toothed rack 18, limiting the clamping block 14. After the cutting is completed, the pull plate 23 is pulled again, and the spring 16 can push the clamping block 14 upward to release the clamping of the PVC hose. Example 2

[0021] like Figure 1 , Figure 4 and Figure 5 As shown, based on embodiment 1, it also includes an installation component including two guide bars 6, an installation plate 7, two limiting sliders 8, and an installation seat 9.
