Description

Technical Field

[0001] This utility model relates to the field of paper tube production technology, and in particular to a fully automatic high-speed paper tube slitting device. Background Technology

[0002] The fully automatic high-speed paper tube slitting equipment is a type of mechanical equipment specifically designed for the efficient and precise slitting of paper tubes. Its main function is to efficiently and continuously slit raw paper tubes through processes such as automatic feeding, precise cutting, and finished product conveying to meet production needs. This equipment typically has multiple operations such as automatic feeding, cutting, and finished product sorting, and features high efficiency, high precision, and stability. It is widely used in industries such as paper tube manufacturing, packaging, and building materials.

[0003] Traditional fully automatic high-speed paper tube slitting equipment can only cut paper tubes of the same diameter. When slitting paper tubes of different diameters, it is necessary to change the clamps, which increases the workload and consumes a lot of time. Secondly, traditional paper tube slitting equipment generates a lot of dust during the cutting process, and existing equipment often does not have a dust collection function. Therefore, the waste and dust generated during the paper tube slitting process are easily scattered and pollute the working environment.

[0004] Therefore, those skilled in the art have provided a fully automatic high-speed paper tube slitting device to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fully automatic high-speed paper tube slitting device. This device utilizes a fourth motor to drive a second driving wheel, which in turn drives a second driven wheel, which in turn drives a second electric telescopic rod inside the driven wheel and a rotating ring at the front end of the driven wheel. The rotating ring then drives a fixed rod, causing the expansion plate to rotate and thus the paper tube being held in place, facilitating high-speed cutting. Activating the second electric telescopic rod pushes a push rod, which in turn drives an extrusion rod to push the expansion plate out or retract it, thereby changing the diameter. This mechanism can cut paper tubes of different diameters, improving its applicability.

[0024] Working principle: The second motor 14 is started, driving the threaded rod 15 to rotate, thus moving the push plate 16 back and forth, adjusting the feed discs 18 on both sides to the appropriate position. The first motor 12 is started, driving the first driven wheel 17 to rotate via the first driving wheel 13. The first driven wheel 17 drives the feed disc 18 to rotate, throwing the paper tube to be cut onto the surface of the expansion plate 309. The second electric telescopic rod 305 is started, pulling the push rod 3011. The extrusion rod 3013, hinged to the surface of the push rod 3011, moves backward, pushing the expansion plate 309 out. The first limiting rod 3012 limits the expansion plate 309, allowing it to move only up and down, thus... By changing the diameter, the paper tube is secured. The fourth motor 303, fixed to the support plate 302, drives the second drive wheel 307 to rotate. The second drive wheel 307, through the second driven wheel 308, drives the second electric telescopic rod 305 inside the second driven wheel 308 to rotate in the bearing seat 306 fixed to the support plate 302. The second driven wheel 308 drives the rotating ring 304 to rotate, which in turn drives the fixed rod 3010 to rotate. This causes the expansion plate 309 to rotate the secured paper tube. The first electric telescopic rod 20 is then activated to push the connecting plate 21, causing the first connecting rod 22 to rotate inside the rotating block 24. The first connecting rod 22 lifts the second connecting rod 23, allowing the slitting roller 19 to adapt to changes in the paper tube diameter. The third motor 25 is activated, driving the slitting roller 19 to rotate and cut the paper tube. The fixing plate 402 is then inserted into the slide groove 409, and the spring 405 rebounds, pushing out the locking block 403 and fixing the fixing plate 402 in the slide groove 409. The fifth motor 4018 is activated, driving the fan blades 4020 to rotate, generating suction to draw the waste and dust generated during paper tube cutting into the dust collection frame 401. The first filter 4013 filters out larger waste materials, and the second filter 4015 filters out fine dust. Further cleaning is required. When cleaning the vacuum cleaner frame 401, pull the pull ring 4022. The fixing plate 402 presses the locking block 403 to compress the spring 405 inward, releasing the limit of the fixing plate 402 and pulling out the vacuum cleaner frame 401. Use the pull handle 4014 to pull out the first filter screen 4013 from the placement groove 4012 for cleaning. Use the handle 4017 to pull out the fixing blocks 4016 on both sides of the second filter screen 4015 from the fixing groove 4011 for cleaning. After cutting, the electric slide rail 8 drives the electric slider 7. The electric slider 7 drives the push ring 11 on the damping rod 10 through the connecting rod 9 to use inertia to unload the cut paper tube from the expansion plate 309.
