Specific embodiments
[0019] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] Please refer to Figure 1 , Figure 2 and Figure 3 , the present utility model provides a technical solution: a PVC plastic pipe cutting device, including an operating table 1, a support frame 2 is fixedly connected to the top surface of the operating table 1, a cylinder 3 is fixedly connected to the top end of the support frame 2, the output end of the cylinder 3 extends out of the support frame 2 and is fixedly connected to a mounting frame 4, the bottom end of the mounting frame 4 is movably connected to a tool holder 5, the tool holder 5 and the mounting frame 4 are fixed by bolts, a tool 6 is fixedly connected to the bottom end of the tool holder 5, a positioning component 7 is arranged at the top end of the operating table 1, and a length control component 8 is movably connected inside the operating table 1.
[0021] Place the plastic pipe between the positioning plates 73 of the two positioning components 7 at the top end of the operating table 1, and cooperate with the guide rod 72, the fixing plate 71 and the positioning spring 74 to position the plastic pipe, which is beneficial to improving the cutting effect;
[0022] Rotate the second turntable in the rotation length control assembly 8 to drive the rotation of the second threaded rod 83, thereby driving the second measuring plate 84 to move away from the operating table 1. Cooperating with the scale 85, the length of the second measuring plate 84 extending out of the operating table 1 can be known in time. Then, push the plastic pipe towards the direction of the second measuring plate 84 until it contacts the second measuring plate 84. Thus, not only can the cutting length of the plastic pipe be accurately controlled according to actual needs, but also the space occupied by the equipment can be reduced, which is convenient for storing and moving the equipment. When the length of the second measuring plate 84 is insufficient, rotate the first turntable to drive the rotation of the first threaded rod 81, thereby driving the first measuring plate 82 to move away from the operating table 1, and the range of controlling the cutting length can be extended and enlarged. The cutting of the plastic pipe can be completed through the cylinder 3, the mounting bracket 4 and the cutter 6. Since the tool holder 5 is fixed to the mounting bracket 4 by bolts, it is convenient to replace the cutter 6.
[0023] Please refer to Figure 1 、 Figure 2 and Figure 3 , the positioning assembly 7 includes a fixing plate 71 fixedly connected to the top end of the operating table 1. A plurality of guide rods 72 are slidably connected in the fixing plate 71. A positioning plate 73 is fixedly connected to the side of the guide rod 72 away from the fixing plate 71. A positioning spring 74 is sleeved on the surface of the guide rod 72. The positioning spring 74 is fixedly connected between the fixing plate 71 and between the positioning spring 74 and the positioning plate 73. Place the plastic pipe between the two positioning plates 73 at the top end of the operating table 1. During this process, the positioning plate 73 will drive the guide rod 72 to move towards the fixing plate 71 and compress the positioning spring 74. When the bottom end of the plastic pipe contacts the top end of the operating table 1, the positioning spring 74 will reset and push the positioning plate 73 towards the plastic pipe, and the plastic pipe can be positioned, which is beneficial to improving the cutting effect.
[0024] The length control component 8 includes a first threaded rod 81 rotatably connected to the inner wall of the operating table 1. One end of the first threaded rod 81 extends out of the operating table 1 and is fixedly connected to a first turntable. A first measuring plate 82 is threadedly connected to the surface of the first threaded rod 81. A second threaded rod 83 is rotatably connected to the inner wall of the first measuring plate 82. One end of the second threaded rod 83 extends out of the first measuring plate 82 and is fixedly connected to a second turntable. A second measuring plate 84 is threadedly connected to the surface of the second threaded rod 83. Scales 85 are fixedly connected to the surfaces of the first measuring plate 82 and the second measuring plate 84. Rotating the second turntable causes it to drive the second threaded rod 83 to rotate, thereby driving the second measuring plate 84 to move away from the operating table 1 along the second threaded rod 83. During this process, by observing the scale 85, the length of the second measuring plate 84 extending out of the operating table 1 can be known in a timely manner. Then, the plastic pipe placed on the top of the operating table 1 is pushed towards the direction of the second measuring plate 84 until it contacts the second measuring plate 84. Thus, not only can the cutting length of the plastic pipe be accurately controlled according to actual needs, but also the space occupied by the equipment can be reduced, facilitating the storage and movement of the equipment. When the length of the second measuring plate 84 is insufficient, rotate the first turntable to drive the first threaded rod 81 to rotate, thereby driving the first measuring plate 82 to move away from the operating table 1 along the first threaded rod 81, and the range of controlling the cutting length can be extended and enlarged.
[0025] Grinding sheets 9 are fixedly connected to both sides of the cutter 6, and the side surfaces of the grinding sheets 9 are flush with the side surfaces of the cutter 6. By providing the grinding sheets 9 with side surfaces flush with the side surfaces of the cutter 6, the cutting part of the plastic pipe can be ground while cutting the plastic pipe, thereby improving the cutting effect of the plastic pipe.
[0026] A relief groove is formed on the surface of the positioning plate 73, and the width of the relief groove is the same as the width of the cutter 6. By providing the relief groove with the same width as the cutter 6, the movement of the cutter 6 can be prevented from being blocked by the positioning plate 73.
[0027] A first anti-slip pad 10 is fixedly connected to one side of the positioning plate 73 away from the positioning spring 74, and a second anti-slip pad 11 is fixedly connected to the bottom end of the operating table 1. By providing the first anti-slip pad 10, the friction between the positioning plate 73 and the plastic pipe can be increased, thereby further improving the positioning effect on the plastic pipe. By providing the second anti-slip pad 11, the friction between the operating table 1 and the placement surface can be increased, thereby improving the stability of the equipment during use.
[0028] The second measuring plate 84 is in an "L" shape, and the center point of the second measuring plate 84 is on the same horizontal line as the center point of the operating table 1. The second measuring plate 84 being in an "L" shape and its center point being on the same horizontal line as the center point of the operating table 1 ensures that the second measuring plate 84 can contact the plastic pipe.
[0029] Specific implementation method: Place the plastic pipe between the two positioning plates 73 at the top of the operating table 1. During this process, the positioning plates 73 will drive the guide rods 72 to move towards the fixed plate 71 and compress the positioning springs 74. When the bottom end of the plastic pipe contacts the top of the operating table 1, the positioning springs 74 will reset and push the positioning plates 73 towards the plastic pipe, thereby positioning the plastic pipe, which is beneficial to improving the cutting effect;
[0030] Rotate the second turntable to drive the second threaded rod 83 to rotate, thereby driving the second measuring plate 84 to move along the second threaded rod 83 away from the operating table 1. During this process, by observing the scale 85, the length of the second measuring plate 84 extending out of the operating table 1 can be known in a timely manner. Then, push the plastic pipe placed on the top of the operating table 1 towards the second measuring plate 84 until it contacts the second measuring plate 84. Thus, not only can the cutting length of the plastic pipe be accurately controlled according to actual needs, but also the space occupied by the equipment can be reduced, facilitating the storage and movement of the equipment. When the length of the second measuring plate 84 is insufficient, rotate the first turntable to drive the first threaded rod 81 to rotate, thereby driving the first measuring plate 82 to move along the first threaded rod 81 away from the operating table 1, so as to extend and expand the range of controlling the cutting length. Then, start the cylinder 3 to drive the cutter 6 to move towards the plastic pipe through the mounting bracket 4, and the cutting of the plastic pipe can be completed. Since the cutter holder 5 and the mounting bracket 4 are fixed by bolts, it is convenient to replace the cutter 6.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
