Description

Technical Field

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

[0002] Plastic water pipes are piping systems made primarily of thermoplastic plastics, used for transporting water (including drinking water, domestic water, and industrial water). Products consisting of plastic water pipes are typically made by connecting multiple pipes together; therefore, appropriate equipment is required to cut the plastic water pipes.

[0003] However, in the existing technology, the cutting is usually done manually with a handheld cutting tool. Before cutting, the plastic water pipe is measured and the cutting position is marked to reduce the error of the cut water pipe. However, during the cutting process, the operator needs to avoid shaking the cutting tool and needs to rely on experience to avoid the cutting device tilting relative to the water pipe, which requires a certain level of skill from the operator. Utility Model Content

[0004] The purpose of this invention is to provide a plastic water pipe cutting device that can automatically cut water pipes and mark the position on the water pipe where the cutting blade will cut before cutting, making it easier for workers to adjust and reducing the technical requirements for water pipe cutting.

[0005] To achieve the above objectives, a plastic water pipe cutting device is provided, including a worktable. The surface of the worktable has a first sliding groove and a cutting groove, with the first sliding groove symmetrically arranged on both sides of the cutting groove. A cutting mechanism and a controller are fixedly connected to the upper end of the worktable. The cutting groove is located in the lower middle part of the cutting mechanism. Two slide rails are fixedly connected to the bottom of the worktable, with the slide rails located on one side of the first sliding groove. Two clamping mechanisms are slidably connected in the slide rails, with the end of the clamping mechanism away from the slide rail passing through the first sliding groove and upwards through the worktable. Support legs are fixedly connected to the four corners of the lower end of the worktable. The cutting mechanism consists of a cylinder, a top plate, a support column, a marking device, and a cutting... The cutting machine consists of a main body with support columns on both sides of the cutting groove and fixedly connected to the upper part of the worktable. A top plate is fixedly connected to the upper end of the support columns. A cylinder is fixedly connected to the upper middle part of the top plate, with its piston rod penetrating downwards and slidingly connected to it. The main body of the cutting machine is positioned above the middle of the cutting groove, with the piston rod of the cylinder fixedly connected to the upper middle part of the main body. Sliding sleeves are fixedly connected to both sides of the main body, with the support columns passing through and slidingly connected to them. A marking device is installed on one side of the cutting groove and fixedly connected to the side end of the support column, with the marking device's nozzle angled downwards towards the middle of the cutting groove. This machine can automatically cut water pipes and marks the position where the cutting blade will cut on the pipe before cutting, facilitating adjustments by the operator and reducing the technical requirements for water pipe cutting.

[0006] According to the aforementioned plastic water pipe cutting device, the clamping mechanism comprises a clamping block, a hand-tightening bolt, a sleeve, a second slider, a connecting plate, and a locking plate. The second slider is disposed in a slide rail and slidably connected to the slide rail. The connecting plate is fixedly connected to the lower end of the second slider, and extends downward through the slide rail to the side of the slide rail facing the adjacent first slide groove. The clamping block is fixedly connected to the end of the connecting plate away from the slide rail, and the upper end of the clamping block extends through the first slide groove to the upper end of the worktable. The sleeve is fixedly connected to the end of the clamping block away from the cutting mechanism, and the sleeve is located above the worktable. The hand-tightening bolt is disposed in the middle of the upper end of the sleeve, and extends into the sleeve and is threadedly connected to the sleeve. The locking plate is disposed in the sleeve and slides, and the bottom of the hand-tightening bolt and the middle of the upper end of the locking plate are rotatably connected. The clamping block is used to approach and clamp the water pipe in the first slide groove. The hand-tightening bolt cooperates with the locking plate to make the locking plate tightly adhere to the surface of the worktable, and the second slider is fixed to the worktable by friction.

[0007] According to the aforementioned plastic water pipe cutting device, the cutting machine body includes a cutting blade that can pass downward through a cutting groove. Two T-shaped second sliding grooves are symmetrically formed on both sides of the cutting machine body. A first slider is slidably connected to each of the second sliding grooves. Protective plates are slidably connected to both sides of the cutting machine body. The first sliders and the protective plates are fixedly connected. A spring is fixedly connected to the upper end of the protective plate, and the upper end of the spring is fixedly connected to the cutting machine body. While the cutting blade cuts the water pipe, the protective plates simultaneously shield the cutting blade. The springs ensure that the protective plates continue to provide protection while the cutting machine body is cutting the water pipe, preventing workers from contacting the cutting blade from the side of the cutting machine body and reducing safety hazards.

[0008] According to the aforementioned plastic water pipe cutting device, a protective plate on the surface of the cutting machine body is located above the worktable between the cutting groove and the first slide groove. This ensures that the protective plate maintains its protective function when there are no water pipes on the device and during the cutting mechanism's operational testing.

[0009] According to the aforementioned plastic water pipe cutting device, the controller includes control buttons and a display panel. The control buttons and display panel enable the controller to control the marking device and cutting mechanism in the device and display the working status.

[0010] According to the aforementioned plastic water pipe cutting device, the protective plate is made of transparent acrylic material. This allows workers to easily observe the cutting process of the water pipe by the main body of the cutting machine.

[0011] The above-mentioned solution has the following beneficial effects:

[0012] 1. The water pipe is fixed by the clamping mechanism, making the water pipe perpendicular to the cutting groove. The main body of the cutting machine cuts the water pipe. The marking instrument emits a visible laser beam into the center of the cutting groove. When the water pipe passes through the cutting mechanism, the laser will mark the surface of the water pipe to indicate the cutting position, which is convenient for the staff to adjust and reduces the technical requirements.

[0013] 2. The cutting blade is shielded by a protective plate. The spring allows the protective plate to continue its protective function while the main body of the cutting machine is cutting the water pipe, preventing workers from coming into contact with the cutting blade from the side of the main body of the cutting machine and reducing safety hazards.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The line marker 12 works and emits a laser beam to irradiate the upper surface of the water pipe. Then, the two clamping mechanisms 6 in the first sliding groove 5 are slid to contact the water pipe. After contact, the locking plate 25 is contacted with the workbench 4 by rotating the hand-tightening bolt 21, thereby using friction to prevent the clamping mechanism 6 from moving. Then, the position of the water pipe is adjusted so that the drawn line and the laser emitted by the line marker 12 are completely aligned. The control cylinder 9 extends upward, and at the same time, the main body of the cutting machine 15 works, causing the cutting blade 18 to rotate at high speed to cut the water pipe. During the cutting process, the protective plate 13 contacts the upper surface of the water pipe and slides relative to the surface of the main body of the cutting machine 15. The spring 14 is compressed by force until the cylinder 9 is fully extended. After that, the main body of the cutting machine 15 completes the cutting of the water pipe. Finally, the cylinder 9 drives the main body of the cutting machine 15 to return to its original position. During the process, the elasticity of the spring 14 recovers, causing the protective plate 13 to gradually return to its original position.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
