Description

Technical Field

[0001] The utility model relates to a pipe cutting device, in particular to a paper tube cutting device, belonging to the technical field of paper tube production. Background Technique

[0002] At present, toilet paper is an essential daily necessity in our life. Generally, a paper tube is arranged in the middle of the toilet paper. During the production process of the paper tube, it is generally composed of cutting a long tube into multiple short tubes that meet the dimensions. At present, during the cutting process of the existing paper tube cutting machines, most of them continuously sleeved the paper tubes on the feeding tube manually. Since the radius of the feeding tube is fixed, paper tubes of different models cannot be fitted and sleeved on the feeding tube, thus affecting the subsequent cutting of the paper tubes.

[0003] Chinese Patent Application No.: CN202122563199.7 discloses a pipe cutting device for paper tube production and processing, including a processing table. A first motor is fixedly installed in the middle on the left side of the processing table. The driving output end of the second motor is in transmission connection with a transmission shaft, and the other end of the transmission shaft is fixedly connected with a turntable. A plurality of groups of equally spaced feeding rods are movably installed on the outer side of the right end of the turntable. The left sides of two adjacent groups of the feeding rods are in transmission connection through a transmission belt. When the feeding rod sleeved with the paper tube rotates to the upper side, it will drive the hydraulic push rod on the support plate to push two limit rods to move downward, so that the rotating cutting rod cuts the paper tube. And through the support, the pressing roller and the third motor, the rotation direction of the motor shaft of the third motor can be controlled to change the rotation direction of the pressing roller. It can not only push out the cut paper tube from the feeding rod, but also when the rotation direction of the pressing roller is opposite, a new paper tube can be sleeved on the feeding rod.

[0004] However, the feeding tube in this patent is fixedly connected to the turntable. When the radius of the paper tube is too large, at this time, when the paper tube is sleeved on the feeding tube, the paper tube cannot fit with the inner wall of the feeding tube. When the feeding tube rotates, the paper tube will shake at this time. Therefore, we propose a paper tube cutting device. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a paper tube cutting device to solve the above problems, so as to solve the problem that the feeding tube in the prior art cannot be quickly replaced and disassembled.

[0006] Technical Solution

[0007] The present utility model is realized through the following technical solutions: A paper tube cutting device, comprising a bracket and a cutting mechanism. One side of the bracket is rotatably connected to a disc. The side of the disc away from the bracket is fixedly connected to a frame. The side of the bracket away from the disc is fixedly connected to a motor. The output end of the motor penetrates the bracket and is fixedly connected to the side surface of the disc. One side of the frame is symmetrically and fixedly connected with two cylindrical blocks. A clamping assembly is arranged inside the cylindrical blocks. The surfaces of the two cylindrical blocks are both fixedly connected with hollow tubes. A supporting assembly is arranged inside the hollow tubes. Two feeding tubes are detachably connected to the sides of the two cylindrical blocks and outside the hollow tubes.

[0008] Preferably, the clamping assembly includes two bidirectional lead screws. The two bidirectional lead screws are respectively rotatably installed inside the two cylindrical blocks. The outer walls of the two bidirectional lead screws are both symmetrically threadedly connected with two first sliders. One end of each first slider extends to the outside of the corresponding cylindrical block and is fixedly connected with a first convex block. One end of each first convex block away from the first slider extends to the outside of the feeding tube. One end of each bidirectional lead screw extends to the outside of the corresponding cylindrical block and is fixedly connected with a handwheel.

[0009] Preferably, the supporting assembly includes a cross plate. The cross plate is fixedly installed on the inner wall of the hollow tube. The top and bottom of the cross plate are both fixedly connected with a plurality of second convex blocks. A cross bar is fixedly connected between every two corresponding second convex blocks. The outer walls of each cross bar are both symmetrically slidably connected with two second sliders. A plurality of vertical rods are slidably connected inside the hollow tube. The top of each vertical rod extends to the outside of the hollow tube and is fixedly connected with a top plate. One side of each top plate is in contact with the inner wall of the feeding tube.

[0010] Preferably, two springs are symmetrically sleeved on the outer wall of each cross bar. One end of each spring is fixedly connected with one side of the corresponding second convex block. The end of each spring away from the second convex block is fixedly connected with one side of the corresponding second slider.

[0012] Preferably, the inside of the bracket is slidably connected with the outer wall of the cutting mechanism.

[0013] The present utility model provides a paper tube cutting device, and the beneficial effects thereof are as follows:

[0014] By rotating the handwheel, the handwheel drives the bidirectional lead screw to rotate. The bidirectional lead screw drives the first slider to slide, and the first slider drives the first convex block to move, so that the first convex block extends to the outside of the feeding pipe. When one side of the first slider contacts the inner wall of the feeding pipe, the clamping of the feeding pipe with different radii and the cylindrical block is realized, which is convenient for cutting straight pipes with different radii.

[0015] The inner wall of the feeding pipe presses against the top plate, the top plate presses against the vertical rod, and the vertical rod slides downward to drive the corresponding two inclined rods to move in opposite directions. The two inclined rods drive the two second sliders to slide to both sides. At the same time, the two second sliders compress the spring, so that the vertical rod and the top plate can support the inner wall of the feeding pipe with different radii, further improving the connection stability between the feeding pipe and the cylindrical block.

[0022] Please refer to Figures 1-4 , an embodiment of the present utility model provides a paper tube cutting device, which includes a bracket 1 and a cutting mechanism 10. A disc 2 is rotatably connected to one side of the bracket 1. A frame 3 is fixedly connected to the side of the disc 2 away from the bracket 1. A motor 4 is fixedly connected to the side of the bracket 1 away from the disc 2. The output end of the motor 4 penetrates through the bracket 1 and is fixedly connected to the side surface of the disc 2. Two cylindrical blocks 5 are symmetrically and fixedly connected to one side of the frame 3. A clamping assembly 8 is arranged inside the cylindrical block 5. Hollow tubes 6 are fixedly connected to the surfaces of the two cylindrical blocks 5. A support assembly 9 is arranged inside the hollow tube 6. Two feeding pipes 7 are detachably connected to the sides of the two cylindrical blocks 5 and outside the hollow tube 6.

[0023] Further, the clamping assembly 8 includes two bidirectional lead screws 81 which are respectively rotatably installed inside two cylindrical blocks 5. Both outer walls of the two bidirectional lead screws 81 are symmetrically threadedly connected with two first sliders 82. One end of each first slider 82 extends to the outside of the corresponding cylindrical block 5 and is fixedly connected with a first convex block 83. One end of each first convex block 83 away from the first slider 82 extends to the outside of the feeding pipe 7. One end of each bidirectional lead screw 81 extends to the outside of the corresponding cylindrical block 5 and is fixedly connected with a handwheel 84.

[0024] During operation, rotate the handwheel 84. The handwheel 84 drives the bidirectional lead screw 81 to rotate. The bidirectional lead screw 81 drives the first slider 82 to slide. The first slider 82 drives the first convex block 83 to move, so that the first convex block 83 extends to the outside of the feeding pipe 7. When one side of the first slider 82 contacts the inner wall of the feeding pipe 7, the clamping of the feeding pipe 7 with different radii and the cylindrical block 5 is realized, which is convenient for cutting straight pipes with different radii.

[0025] Further, the support assembly 9 includes a cross plate 91 which is fixedly installed on the inner wall of the hollow pipe 6. Both the top and bottom of the cross plate 91 are fixedly connected with a plurality of second convex blocks 92. A cross bar 94 is fixedly connected between every two corresponding second convex blocks 92. Both outer walls of each cross bar 94 are symmetrically slidably connected with two second sliders 93. A plurality of vertical rods 97 are slidably connected inside the hollow pipe 6. The top of each vertical rod 97 extends to the outside of the hollow pipe 6 and is fixedly connected with a top plate 98. One side of each top plate 98 contacts the inner wall of the feeding pipe 7.

[0026] During operation, the inner wall of the feeding pipe 7 squeezes the top plate 98. The top plate 98 squeezes the vertical rod 97. The vertical rod 97 slides downward to drive the two corresponding inclined rods 96 to move in opposite directions. The two inclined rods 96 drive the two second sliders 93 to slide apart.

[0027] Further, two springs 95 are symmetrically sleeved on the outer wall of each cross bar 94. One end of each spring 95 is fixedly connected with one side of the corresponding second convex block 92. One end of each spring 95 away from the second convex block 92 is fixedly connected with one side of the corresponding second slider 93.

[0028] During operation, the two second sliders 93 squeeze the springs 95, so that the vertical rod 97 and the top plate 98 can support the inner wall of the feeding pipe 7 with different radii, further improving the connection stability between the feeding pipe 7 and the cylindrical block 5.

[0029] Further, one side of each second slider 93 is rotatably connected with an inclined rod 96. One end of each two corresponding inclined rods 96 away from the second slider 93 is rotatably connected with the vertical rod 97 through a shaft body.

[0030] Further, the inside of the bracket 1 is slidably connected with the outer wall of the cutting mechanism 10.

[0031] Working principle: First, the operator selects the feeding pipe 7 according to the radius of the paper tube, and then rotates the handwheel 84. The handwheel 84 drives the bidirectional lead screw 81 to rotate. The bidirectional lead screw 81 drives the slider 82 to slide. The slider 82 drives the convex block 83 to move, so that the convex block 83 extends outside the feeding pipe 7. When the side of the slider 82 close to the inner wall of the feeding pipe 7 contacts the inner wall of the feeding pipe 7, the clamping connection between the feeding pipe 7 and the cylindrical block 5 is realized, which is convenient for subsequent cutting of the paper tube. At the same time, in order to improve the stability of the feeding pipe 7 and prevent shaking during the cutting of the straight pipe, the inner wall of the feeding pipe 7 presses the top plate 98. The top plate 98 presses the vertical rod 97. The vertical rod 97 slides downward to drive the corresponding two inclined rods 96 to move in opposite directions. The two inclined rods 96 drive the two sliders 93 to slide to both sides. At the same time, when the two sliders 93 slide, they press the corresponding springs 95, so that the vertical rod 97 and the top plate 98 can support the inner wall of the feeding pipe 7, further improving the connection stability between the feeding pipe 7 and the cylindrical block 5.
