Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 invention and do not limit the invention.

[0020] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0021] Please see Figure 1 The present invention provides a cutting device for processing plastic pipes, the cutting device for processing plastic pipes includes:

[0022] The system comprises a base 1 and a storage box 2, the storage box 2 being fixedly mounted on the base 1 for storing items, and a platform 3 fixedly mounted on the storage box 2; a support plate 4, fixedly mounted on the platform 3 and having an opening for a plastic tube to pass through, with a cavity formed on the upper side of the opening; a top plate 5 fixedly mounted on the support plate 4; a cutting mechanism 6, mounted on the platform 3 and the support plate 4, the power output end of the cutting mechanism 6 being able to reciprocate up and down to cut the plastic tube; and a hanging plate 7, the end of which is fixedly connected to the top plate 5, with a pushing mechanism mounted on the hanging plate 7 and the support plate 4. The mechanism 8 is intermittently engaged with the cutting mechanism 6 to intermittently push the plastic tube forward through the opening; the clamping mechanism 9 is installed at the opening of the support plate 4 to clamp the plastic tube passing through the opening to maintain the stability of the plastic tube cutting; the guide groove 10 is fixedly installed on the platform 3, and the plastic tube can be placed in the guide groove 10. The power output end of the pushing mechanism 8 is set in the guide groove 10 to push the plastic tube to move stably in the guide groove 10; the support plate 11 is fixedly installed on the platform 3, and the support plate 11 is provided with a collection box 12 for collecting the cut plastic tube.

[0023] When using this plastic pipe processing cutting device, first adjust the cutting mechanism 6. Determine the required pipe length by meshing the cutting mechanism 6 with the pushing mechanism 8 at different positions. Then, place the plastic pipe to be cut into the guide groove 10 and pass it through the opening. Rotate the control end of the clamping mechanism 9 to clamp the pipe, ensuring the stability of the pipe during cutting. Turn on the cutting mechanism 6, and the power output end of the cutting mechanism 6 will move up and down. At the same time, the cutting mechanism 6 and the pushing mechanism 8 will intermittently mesh, and the pushing mechanism 8 will intermittently push the pipe forward. When the pushing mechanism 8 starts to push the pipe, the cutting mechanism 6 will not cut the pipe. When the pushing mechanism 8 does not push the pipe, the cutting mechanism 6 will cut the pipe. The cut pipe will fall into the collection box 12 for collection.

[0024] like Figure 1 As shown, in a preferred embodiment of the present invention, the cutting mechanism 6 includes: a base 61, which is fixedly mounted on a top plate 5, a first power member 62 is fixedly mounted on the base 61, and a linkage component 63 is fixedly connected to the output shaft of the first power member 62, and the power input end of the pushing mechanism 8 intermittently meshes with the linkage component 63; a cam 64, which is rotatably mounted on a support plate 4 and fixedly connected to the linkage component 63, the first power member 62 is used to drive the cam 64 to rotate stably through the linkage component 63; a reset component 65, which is fixedly mounted on the support plate 4, a roller 66 is fixedly connected to the reset component 65, and the roller 66 and the cam 64 slide in contact; a wheel frame 67, which is fixedly connected to the roller 66, a second power member 68 is mounted on the wheel frame 67, and a cutting wheel 69 rotatably mounted in the wheel frame 67 is fixedly mounted on the output shaft of the second power member 68, the second power member 68 is used to rotate the large hole cutting wheel 69 at high speed to cut the plastic tube.

[0025] When cutting the pipe, the control end of the linkage component 63 can be rotated to engage with the push mechanism 8 at different positions to adjust the pipe cutting length. During cutting, the first power component 62, which is a motor, is activated. The output shaft of the first power component 62 drives the linkage component 63 to rotate, which in turn drives the push mechanism 8 to intermittently push the plastic pipe forward. At the same time, the linkage component 63 drives the cam 64 to rotate. Under the elastic force of the reset component 65, the roller 66 drives the cutting wheel 69 on the wheel frame 67 to move up and down reciprocally. The second power component 68, which is a motor, is activated. The output shaft of the second power component 68 drives the cutting wheel 69 to rotate at high speed. The cutting wheel 69 moves downward to cut the plastic pipe.

[0026] like Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the linkage component 63 includes: a transverse rod 631, which has two parts and one end is fixedly connected to a connecting plate 632, the output shaft of the first power component 62 is fixedly connected to the connecting plate 632, the other end of the transverse rod 631 is fixedly connected to the cam 64, and a threaded plate 633 is fixedly provided on the transverse rod 631; a movable sleeve 634, which is sleeved on the transverse rod 631, and a handle 635 is rotatably provided on the movable sleeve 634, and a first bevel gear 636 is fixedly provided inside the movable sleeve 634 on the handle 635; a threaded rod 637, both ends of which are rotatably connected to the inner wall of the movable sleeve 634, and the threaded plate 633 is threadedly sleeved on the threaded rod 637, and a second bevel gear 638 that meshes with the first bevel gear 636 is fixed on one side of the threaded rod 637; and an incomplete gear 639, which is fixed on the movable sleeve 634, and the power input end of the pushing mechanism 8 intermittently meshes with the incomplete gear 639.

[0027] After the first power component 62 is activated, the output shaft of the first power component 62 drives the connecting plate 632 to rotate. The connecting plate 632 drives the transverse rod 631 and the moving sleeve 634 to rotate. The rotation of the transverse rod 631 drives the cam 64 to rotate. At the same time, the rotation of the transverse rod 631 drives the moving sleeve 634 to rotate, thereby driving the incomplete gear 639 to rotate. Since the incomplete gear 639 and the push mechanism 8 are intermittently meshed, the push mechanism 8 can intermittently push the plastic tube forward. To adjust the meshing position of the incomplete gear 639 and the push mechanism 8, turn the handle 635. The handle 635 drives the first bevel gear 636 to rotate. The first bevel gear 636 drives the second bevel gear 638 and the threaded rod 637 to rotate. The rotation of the threaded rod 637 can drive the moving sleeve 634 to move along the threaded plate 633 and the transverse rod 631, thereby driving the incomplete gear 639 and the push mechanism 8 to mesh at different positions.

[0028] like Figure 4 As shown, in a preferred embodiment of the present invention, the reset assembly 65 includes: a groove 651, which is fixedly mounted on the support plate 4, a sliding post 652 is fixedly disposed on the inner wall of the groove 651, a sliding plate 653 is sleeved on the sliding post 652, and a push spring 654 for pushing the sliding plate 653 to move upward and reset is fixedly connected between the sliding plate 653 and the inner wall of the groove 651; an extension plate 655, one end of which is fixedly connected to the sliding plate 653, and a roller 66 is fixedly connected to the other end of the extension plate 655.

[0029] As the protruding end of the cam 64 gradually rotates upward, the push spring 654 can push the slide plate 653 and the extension plate 655 to move upward along the slide column 652. The upward movement of the extension plate 655 can drive the roller 66 to move upward, thereby driving the cutting wheel 69 to move upward and reset.

[0030] like Figure 1 As shown, in a preferred embodiment of the present invention, the pushing mechanism 8 includes: a lead screw 81, one end of which is rotatably connected to the hanging plate 7, a handle 82 for controlling its rotation is fixed on the lead screw 81, and a wheel rod 83 rotatably connected to the support plate 4 is fixedly connected to the other end of the lead screw 81, and a linkage gear 84 intermittently meshing with the incomplete gear 639 is fixedly provided on the wheel rod 83; a stabilizing rod 85, both ends of which are fixedly connected to the hanging plate 7 and the support plate 4 respectively, and a moving block 86 threadedly connected to the lead screw 81 is sleeved on the stabilizing rod 85; and an L-shaped rod 87, one end of which is fixedly connected to the moving block 86, and the other end of which is fixedly connected to a push plate 88, which is disposed in the guide groove 10.

[0031] like Figure 1As shown, in a preferred embodiment of the present invention, three linkage gears 84 are provided, and the number of teeth of the three linkage gears 84 is different. The incomplete gear 639 can mesh with the three different linkage gears 84 to adjust the cutting length of the plastic tube.

[0032] When the incomplete gear 639 and the linkage gear 84 are engaged, the rotation of the incomplete gear 639 can drive the linkage gear 84 and the wheel rod 83 to rotate. The rotation of the wheel rod 83 drives the lead screw 81 to rotate. The rotation of the lead screw 81 can cause the moving block 86 to drive the L-shaped rod 87 and the push plate 88 to move along the stabilizing rod 85. The movement of the push plate 88 can push the plastic tube forward. When the incomplete gear 639 and the linkage gear 84 are no longer engaged, the cutting wheel 69 can move downward and cut the plastic tube.

[0033] In this embodiment, the movement of the incomplete gear 639 can mesh with three linkage gears 84 with different numbers of teeth, thereby changing the transmission ratio between the incomplete gear 639 and the linkage gears 84. The change in transmission ratio can change the distance that the cutting pusher 88 pushes the plastic tube each time, thereby adjusting the length of the plastic tube cut. The specific number of teeth of the three linkage gears 84 with different numbers of teeth can be determined according to actual needs, and this application does not make specific limitations.

[0034] like Figure 5 As shown, in a preferred embodiment of the present invention, the fastening mechanism 9 includes: a control handle 91, which is rotatably mounted on the support plate 4, and an active bevel gear 92 fixedly disposed in the cavity at the end of the control handle 91, the active bevel gear 92 meshing with a driven bevel gear 93 rotatably mounted on the inner wall of the cavity; a threaded cylinder 94, which is rotatably mounted on the inner wall of the passage and fixedly connected to the driven bevel gear 93, the threaded cylinder 94 being threadedly connected to a threaded post 95, a movable pressure plate 96 fixedly disposed on the threaded post 95, the movable pressure plate 96 cooperating with a fixed pressure plate 97 fixed in the passage; and a guide post 98, both ends of which are fixedly connected to the inner wall of the passage, the movable pressure plate 96 and the fixed pressure plate 97 being sleeved on the guide post 98.

[0035] When pressing the plastic tube, pass the plastic tube to be cut through the opening and place it on the fixed pressure plate 97. Turn the control handle 91, which drives the driving bevel gear 92 to rotate. The driving bevel gear 92 drives the driven bevel gear 93 and the threaded cylinder 94 to rotate. The rotation of the threaded cylinder 94 causes the threaded column 95 to drive the movable pressure plate 96 to move downward along the guide column 98. The downward movement of the movable pressure plate 96 will make it close to the plastic tube. Note that the movable pressure plate 96 should not press the plastic tube too tightly. Ensure that the push plate 88 can push the plastic tube to move. Pressing the plastic tube tightly will ensure the stability of the plastic tube during cutting.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
