[0002] A spandex paper tube is a winding device for winding spandex yarn, which is a cylindrical paper tube with a through hole. Spandex paper tubes are usually made by winding paper.

[0003] In the existing production process of spandex paper tubes, the inner cylinder of the paper tube is generally rotated to realize the wrapping and winding of the paper. After the finished paper tube is wound, it needs to be cut. At present, a cutting knife is usually used to cut the paper directly.

[0004] However, in the actual process of winding the paper tube, the paper is in a floating state, while the cutting knife is stationary relative to the paper. Therefore, when cutting, it is necessary to stop the floating of the paper, and it is necessary to stop the overall transmission equipment and wait for the power to be interrupted, which affects the winding speed. Summary of the Utility Model

[0023] For this specific implementation manner, the mounting base 101 is used to support the lower cutting knife 105, the cylinder 106, the upper cutting knife 107 and the two rolling parts 108.

[0024] Among them, the lifting part 103 is arranged on the side of the mounting seat 101, and the translation part 104 is arranged at the bottom of the lifting part 103; the lower cutting knife 105 is fixedly connected to the mounting seat 101 and is located inside the mounting seat 101; the air cylinder 106 is fixedly connected to the mounting seat 101 and is located on the top of the mounting seat 101; the upper cutting knife 107 is fixedly connected to the output rod of the air cylinder 106 and is located at the bottom of the air cylinder 106; the two rolling parts 108 are arranged symmetrically on both sides of the mounting seat 101. The paper is passed through between the two rolling parts 108, and the paper sheet is passed through between the upper cutting knife 107 and the lower cutting knife 105. The rolling parts 108 roll to drive the paper to feed. At this time, the upper cutting knife 107 and the lower cutting knife 105 are respectively inside the mounting seat 101 and will not interfere with the feeding of the paper. When cutting is required, the power input of the rolling parts 108 is stopped, and the translation part 104 is activated to drive the mounting seat 101 to feed synchronously with the paper. During this period, the air cylinder 106 drives the upper cutting knife 107 to press down and engage with the lower cutting knife 105 to cut the paper. After the cutting is completed, the upper cutting knife 107 resets, the translation part 104 drives the mounting seat 101 to reset, and the rolling parts 108 rotate at an accelerated speed so that the mounting seat 101 can quickly return to its original position on the premise that the paper keeps feeding at the original speed, facilitating the next cutting operation. The lifting part 103 can drive the mounting seat 101 to move longitudinally to adjust the height position of the mounting seat 101 to adapt to different processing environments. In the above way, during the process of winding the spandex paper tube, the paper can be cut without stopping the machine, avoiding affecting the winding speed due to machine stop.

[0025] Secondly, the electric push rod 109 is arranged on the top of the lifting part 103; the connecting arm 110 is fixedly connected to the output rod of the electric push rod 109, and is fixedly connected to the mounting seat 101 and is located between the electric push rod 109 and the mounting seat 101. The electric push rod 109 can drive the connecting arm 110 to move longitudinally, and the connecting arm 110 drives the mounting seat 101 to move longitudinally. By adjusting the height position of the mounting seat 101, different processing environments can be adapted.

[0026] Meanwhile, the guide rail 111 is located at the bottom of the cylinder 106; the slider 112 is slidably connected to the guide rail 111, fixedly connected to the cylinder 106, and located inside the guide rail 111; the screw 113 is rotatably connected to the guide rail 111, threadedly connected to the slider 112, and located inside the guide rail 111; the motor 114 is fixedly connected to the guide rail 111, and the output end of the motor 114 is fixedly connected to the screw 113 and located on the side of the guide rail 111. Turning on the motor 114 can drive the screw 113 to rotate, and the rotation of the screw 113 causes the slider 112 to move along the guide rail 111, thereby driving the mounting seat 101 to move.

The support 115 is used to support the roller 116, and the paper can be moved by the rolling of the roller 116.

[0028] When using the present utility model, the end of the roller 116 is externally connected to a power device, the paper is passed through between the two rollers 116, and the paper sheet is passed through between the upper cutter 107 and the lower cutter 105. The rolling of the roller 116 drives the paper to feed. At this time, the upper cutter 107 and the lower cutter 105 are respectively inside the mounting seat 101 and will not interfere with the feeding of the paper. When cutting is required, the power input of the roller 116 is stopped, the motor 114 is turned on to rotate forward to drive the screw 113 to rotate, and the rotation of the screw 113 causes the slider 112 to move along the guide rail 111, driving the mounting seat 101 to feed synchronously with the paper. During this period, the cylinder 106 drives the upper cutter 107 to press down and engage with the lower cutter 105 to cut the paper. After the cutting is completed, the upper cutter 107 resets, the motor 114 rotates in reverse to drive the mounting seat 101 to reset, and the roller 116 accelerates to rotate, so that on the premise that the paper maintains the original feeding speed, the mounting seat 101 can quickly return to its original position, facilitating the next cutting operation. The electric push rod 109 can drive the mounting seat 101 to move longitudinally to adjust the height position of the mounting seat 101 to adapt to different processing environments. In the above manner, the paper can be cut during the process of winding the spandex paper tube without stopping the machine, avoiding affecting the winding speed due to machine stoppage.
