Description

Technical Field

[0001] This utility model relates to the field of dual-axis slitting machine technology, specifically a material receiving mechanism for a dual-axis slitting machine. Background Technology

[0002] A dual-axis slitting machine is a type of mechanical equipment mainly used to slit wide materials (such as paper, film, etc.) into multiple narrow strips. It uses dual-axis rotating blades for cutting, with the blades independently feeding and laterally slitting, resulting in a more precise cutting effect and making it suitable for thicker materials.

[0003] For example, Chinese utility model patent CN212981961U discloses a slitting machine receiving mechanism, including a frame, a receiving roller mounted on the frame, several air shafts mounted on the receiving roller, and several receiving tubes of different sizes; the inner diameter of the receiving tubes is the same, and the inner diameter of the receiving tubes is the same as the diameter of the air shafts after expansion; the outer diameter of the receiving tubes has different thicknesses to suit the size of the cores of different slitting objects. This utility model effectively improves the problem of cumbersome procedures caused by the need to change the air shaft with the corresponding shaft diameter when receiving different slitting objects.

[0004] When using a twin-shaft slitting machine to slit wide materials, a take-up roller is needed to collect the slit wide materials. Existing take-up rollers mainly consist of a roller and a roller shaft. During production, the roller shaft needs to be processed first, and then the roller is fixed to the surface of the roller shaft by coating with rubber to form the take-up roller. However, the roller is prone to damage during long-term use, while the roller shaft remains intact. Since it is difficult to separate the damaged roller from the roller shaft, the entire take-up roller needs to be replaced periodically. This not only increases the cost of use but also affects the performance of the take-up roller. Utility Model Content

[0029] Example: Figures 1-6As shown, this utility model provides a technical solution for a material receiving mechanism of a dual-axis slitting machine, including a receiving roller body 1 and a connecting assembly 2 for receiving material in the dual-axis slitting machine; the receiving roller body 1 includes a roller shaft body 101 and a roller body 102; the roller shaft body 101 is connected to the dual-axis slitting machine by bolts; the roller body 102 is connected to the roller shaft body 101 by the connecting assembly 2; the connecting assembly 2 includes a connecting groove 201 and a connecting block 202; the connecting groove 201 is provided on the inner surface of the roller body 102; the connecting block 202 is fixed on the surface of the roller shaft body 101 and is movably connected to the connecting groove 201; the connecting block 202 has a spiral structure, and the shape of the connecting block 202 is adapted to the shape of the connecting groove 201, so as to facilitate extending the connection area between the connecting block 202 and the connecting groove 201 and improve the connection stability between the connecting block 202 and the connecting groove 201.

[0030] This invention, by setting up a connecting component 2, allows the connecting block 202 to rotate within the connecting groove 201 by rotating the roller body 102 until the connecting block 202 moves out of the connecting groove 201, thus completing the separation of the roller body 101 and the roller body 102. During installation, the connecting block 202 is rotated into the connecting groove 201 until its side contacts the inner wall of the connecting groove 201. Compared with the prior art, this invention has a simple and reasonable structure and ingenious design. It can separate the roller body 101 and the roller body 102 through the cooperation of the connecting groove 201 and the connecting block 202, making it convenient to replace the roller body 102 and highly practical.

[0031] As a preferred embodiment, it also includes a fixing component 3; the fixing component 3 is arranged on the connecting block 202; the fixing component 3 includes a movable groove 301, a movable block 302, a fixing spring plate 303, a fixing block 304, a receiving groove 305, and a fixing groove 306; the connecting block 202 has a movable groove 301; the movable block 302 slides through the movable groove 301 and is connected to the movable groove 301 through the guide component 4; several fixing spring plates 303 are evenly fixed on one side of the movable block 302; eight fixing blocks 304 are fixed on the opposite side of the eight fixing spring plates 303; the connecting groove 201 has a receiving groove 305; the receiving groove 305 has a fixing groove 306 and engages with the fixing block 304; the fixing block 304 has an ear-shaped structure, and the size of the fixing block 304 on the side closer to the movable block 302 is smaller than the size of the fixing block 304 on the side farther from the movable block 302;

[0032] The guide assembly 4 includes a guide groove 401, a guide block 402, a pull groove 403, and a pull block 404. Two guide grooves 401 are symmetrically opened on both sides of the inner wall of the movable groove 301. The guide block 402 is slidably inserted into the guide groove 401 and fixedly connected to the movable block 302. The length of the guide groove 401 is greater than the length of the fixed spring plate 303 so that when the side of the guide block 402 contacts the inner wall of the guide groove 401, the fixed block 304 can be moved out of the receiving groove 305. The movable block 302 has a pull groove 403 on the side away from the fixed spring plate 303. The pull block 404 is movably inserted into the pull groove 403.

[0033] This invention, by setting a fixing component 3 and a guide component 4, inserts a pulling block 404 into a pulling groove 403 and rotates the pulling block 404 to make it contact the inner wall of the pulling groove 403. Then, pulling the pulling block 404 causes the movable block 302 to slide in the movable groove 301, and the guide block 402 to slide in the guide groove 401. This causes the arc-shaped surface of the fixing block 304 to press against the inner wall of the fixing groove 306, causing the eight fixing spring plates 303 to drive the fixing block 304 to move. The deformation and relative tilting occur until the arc surface of the fixing block 304 contacts the inner wall of the receiving groove 305. At this point, the fixing spring plate 303 no longer deforms until the side of the guide block 402 contacts the inner side wall of the guide groove 401. At this point, the fixing block 304 moves out of the receiving groove 305. By engaging the fixing block 304 with the fixing groove 306, the position of the connecting block 202 can be fixed in the connecting groove 201, making the roller body 101 and the roller body 102 more stably installed.

[0034] Working principle: During replacement, firstly, insert the pull block 404 into the pull groove 403 and rotate the pull block 404 until it contacts the inner wall of the pull groove 403. Then, pull the pull block 404, causing the movable block 302 to slide in the movable groove 301 and the guide block 402 to slide in the guide groove 401. This causes the arc-shaped surface of the fixed block 304 to press against the inner wall of the fixed groove 306, causing the eight fixed spring plates 303 to deform and tilt relative to each other until the arc-shaped surface of the fixed block 304 contacts the inner wall of the receiving groove 305. At this point, the fixed spring plates 303 no longer deform until the guide plate 304 is fully extended. When the side of the connecting block 402 contacts the inner wall of the guide groove 401, the fixing block 304 moves out of the receiving groove 305. Then, the roller body 102 is rotated, causing the connecting block 202 to rotate within the connecting groove 201 until the connecting block 202 moves out of the connecting groove 201. This completes the separation of the roller body 101 and the roller body 102. During installation, the connecting block 202 is rotated into the connecting groove 201, and the side of the connecting block 202 contacts the inner wall of the connecting groove 201. Then, the fixing block 304 is engaged with the fixing groove 306 to fix the position of the connecting block 202 within the connecting groove 201.
