Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically to an automatic arrangement and positioning circular knife slitting mechanism. Background Technology

[0002] A paper slitting machine is an industrial device that can slit a wide master roll of paper into multiple narrow sub-rolls at high speed and with high precision. Its core workflow consists of unwinding, traction and correction, slitting and rewinding. The slitting methods of paper slitting machines are mainly divided into two types: longitudinal slitting using upper and lower circular blades and transverse slitting using straight blades.

[0003] Existing paper slitting machines typically use a longitudinal cutting method with upper and lower circular blades to slit paper. Since different sizes need to be cut according to varying production requirements, the spacing between multiple sets of circular blades needs to be adjusted. This adjustment is generally done manually or with semi-automatic assistance (such as lead screws, worm gears, etc.). Manual adjustment relies on operator experience to judge the spacing and manually push the blade holders, which can easily lead to insufficient positioning accuracy due to measurement deviations and uneven operating force. While semi-automatic assistance saves effort with mechanical structures, it lacks real-time position feedback and precise drive coordination, making it difficult to avoid adjustment errors. Furthermore, both methods require repeated adjustments, resulting in inefficient blade positioning. Therefore, an automatic arrangement and positioning circular blade slitting mechanism is now provided, eliminating the drawbacks of existing devices. Utility Model Content

[0041] In one embodiment, such as Figures 1-5As shown, the automatic arrangement and positioning circular blade slitting mechanism includes an upper circular blade beam 1. A connecting support block 3 is provided at one end of the upper circular blade beam 1. A cylinder 9 is sleeved on the outer wall of the end of the connecting support block 3 away from the upper circular blade beam 1.

The lower circular blade beam 6 is fixedly connected to the support frame 10. The lower circular blade body 13... A connecting drum is fixedly connected to one side of the connecting base 5. The first support 4 is rotatably sleeved on the outer wall of the connecting drum. An air shaft 14 is provided above the connecting base 5. The lower circular blade body 13 and the connecting drum are both sleeved on the outer wall of the air shaft 14. A drive motor is installed on the support frame 10. The air shaft 14 is driven by the output end of the drive motor. The air shaft 14 is rotatably connected to the support frame 10. A snap-fit ​​groove for sliding the connecting support block 3 is provided at the contact position between the cylinder 9 and the connecting support block 3. A snap-fit ​​component 7 is provided on the cylinder 9. The snap-fit ​​component 7 contacts the upper surface of the connecting support block 3. A slitting blade air passage 8 for supplying air to the cylinder 9 is installed on the cylinder 9. A moving module for driving the upper circular blade body 12 and the lower circular blade body 13 to move synchronously is provided on the upper circular blade crossbeam 1 and the lower circular blade crossbeam 6.

[0042] The mobile module includes:

[0062] The clutch assembly includes:

At the same time, through the cooperation of the connecting base 5 and the clutch 209, the belt can be clamped or released so that the belt drive assembly can drive the connecting base 5 to move when running.

[0064] In one embodiment, such as Figures 2-4 As shown, the detection component includes:

[0065] Two position sensors 208 are symmetrically installed at the top of the lower circular blade beam 6. The connecting base 5 is located between the two position sensors 208. A movable detection block is fixedly connected to the outer wall of the connecting base 5. The movable detection block is located above the position sensors 208. The position sensors 208 are electrically connected to the control terminal through wires. Through the cooperation between the position sensors 208 and the movable detection block, the position of the connecting base 5 can be detected in real time during the process of adjusting the position of multiple connecting bases 5 one by one.

[0066] The above embodiments disclose an automatic arrangement and positioning circular knife cutting mechanism. In use, the cylinder 9 is sleeved on the outer wall of the connecting support block 3, and then the outer wall of the connecting support block 3 is clamped and squeezed by the snap-fit ​​component 7, so that the cylinder 9 and the snap-fit ​​component 7 can be easily snapped together. When it is necessary to replace the upper circular knife body 12, the snap-fit ​​component 7 is separated from the connecting support block 3 to facilitate the easy disassembly and replacement of the upper circular knife body 12.

[0067] When it is necessary to adjust the position of the upper circular cutter body 12 and the lower circular cutter body 13, the air pump is started. The pneumatic linkage pin 204 pushes the pin rod through the air passage 2013 via the linkage pin to the bottom of the docking sleeve 205, so that the pneumatic linkage pin 204 and the docking sleeve 205 can be easily connected. Then the air pump is started, and the clutch 209 is driven through the clutch air passage 2010 to squeeze the belt. At this time, the belt can be firmly clamped through the connecting base 5 and the clutch 209. Then the second brake 207 and the first brake 202 are released through the first brake air passage 2011 and the second brake air passage 2012 respectively, so as to release the locking and fixing of the connecting base 5 and the moving slide plate 201.

[0068] Then, the control terminal drives the belt drive assembly to move the connecting base 5 and the clutch 209. At this time, the connecting base 5 slides along the outer wall of the second slide rail 206 via the second slide table under the drive of the belt. At the same time, the docking sleeve 205 moves synchronously via the first support seat 4 and the connecting base 5, through the pin and the pneumatic linkage pin 204 to drive the moving slide plate 201. At this time, the moving slide plate 201 slides along the outer wall of the first slide rail 203 via the first slide table. At the same time, the lower circular cutter body 13 moves synchronously via the connecting drum under the drive of the first support seat 4. At this time, the upper circular cutter body 12 moves synchronously via the second support seat 11, the cylinder 9, and the connecting support block 3 under the drive of the moving slide plate 201. In this way, the positions of the upper circular cutter body 12 and the lower circular cutter body 13 can be adjusted synchronously.

[0069] During this process, the moving detection block moves above the position sensor 208 under the drive of the connecting base 5. At this time, the control terminal detects the position of the moving detection block through the position sensor 208, and can detect the position of the connecting base 5 in real time. When the connecting base 5 moves to the designated position, the belt drive assembly is stopped, and the above operation is reversed, which can realize the convenient adjustment and installation and fixation of a set of tools.

[0070] Then, repeat the above operation to adjust the position of multiple sets of cutters in sequence. After the position of multiple sets of cutters has been adjusted and fixed, the air shaft 14 is started to expand through the control terminal, so that the air shaft 14 can contact the inner wall of multiple lower circular cutter bodies 13. At the same time, the air pump is started through the slitting cutter air passage 8, so that the cylinder 9 can push the second support seat 11 to descend, thereby adjusting the distance between the upper circular cutter body 12 and the lower circular cutter body 13. When slitting the paper, the drive motor is started to drive the air shaft 14 to rotate. At the same time, multiple lower circular cutter bodies 13 rotate synchronously under the drive of the air shaft 14. At this time, the upper circular cutter body 12 rotates under the friction of the paper and the lower circular cutter body 13, thereby performing automatic paper slitting operation.

[0071] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
