Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and in particular to a slitting machine winding paper core positioning mechanism. Background Technology

[0002] A slitting machine is a mechanical device that cuts wide sheets of paper, mica tape, or film into multiple narrow strips of material. It is commonly used in papermaking machinery, wire and cable mica tape, and printing and packaging machinery. When the slitting machine rewinds the slitting material through the paper core, it is necessary to position the paper core to be replaced.

[0003] For example, CN206720400U discloses a slitting machine winding paper core positioning mechanism, including a bracket, a horizontally placed winding shaft for paper core nesting is rotatably connected to the bracket, a guide rail parallel to the axis of the winding shaft is fixedly connected to the bracket, a slider is sleeved on the guide rail and slidably connected along its length direction, and a laser marker is fixedly connected to the slider.

[0004] In existing technologies, the positioning position of the paper core is determined by a laser beam, but manual judgment of the alignment status is still required. The parallax effect causes alignment errors, which leads to deviations in the positioning of the paper core, affecting the positioning accuracy. This, in turn, causes the paper core to move axially or have uneven edges during the winding process. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that the positioning position of the paper core is determined by a laser beam, but still requires manual judgment of the alignment state, which causes the paper core to deviate during positioning. Therefore, this invention proposes a paper core positioning mechanism for a slitting machine winding.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a slitting machine winding paper core positioning mechanism, including a support frame, a replacement mechanism installed on one side of the support frame, and a multi-positioning mechanism installed on the other side of the support frame. The multi-positioning mechanism includes a moving plate, a laser marker fixedly connected to one end of the moving plate, a connecting plate fixedly connected to one side of the moving plate, a positioning rod rotatably connected to one end of the connecting plate, a steering plate fixedly connected to one end of the positioning rod, a positioning block fixedly connected to one end of the steering plate, and a first electric push rod rotatably connected to the other end of the steering plate. One end of the first electric push rod is rotatably connected to one side of the moving plate.

[0007] Preferably, a threaded sleeve is rotatably connected to the inner side of the movable plate, and a threaded rod is threadedly connected to the middle of the threaded sleeve.

[0008] Preferably, both ends of the threaded rod are fixedly connected to a fixing block, and one end of the fixing block is fixedly connected to one side of the support frame.

[0009] Preferably, a steering handle is fixedly connected to one end of the threaded sleeve.

[0010] Preferably, a guide rod is slidably connected to one side of the movable plate, and the end of the guide rod is fixedly connected to the inner side of the support frame.

[0011] Preferably, the replacement mechanism includes a fixed plate, one end of which is rotatably connected to a positioning block, and a sleeve rod is installed on the connection side between the positioning block and the fixed plate.

[0012] Preferably, a push block is fixedly connected to the other side of the positioning block, and a second electric push rod is rotatably connected to one end of the push block. One end of the second electric push rod is rotatably connected to one side of the fixed plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the rotation of the threaded sleeve drives the movement of the moving plate, and the laser marker moves synchronously with the moving plate. The laser line quickly aligns with the paper core. At this time, the first electric push rod works, pushing the steering plate to swing around the positioning rod, so that the positioning block fits the end of the paper core. Through the dual cooperation of laser positioning and mechanical positioning, the accuracy of paper core positioning is improved.

[0015] 2. In this utility model, when the second electric push rod is working, it pushes the block to move, causing the positioning block to rotate around the hinge point of the fixed plate, and respectively stepping in and releasing the sleeve rod, so as to quickly remove the paper core roll that has been wound. After installing the new paper core roll, the second electric push rod extends, the positioning block clamps again, and the roll change is completed. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a positioning mechanism for the winding core of a slitting machine, including a support frame 1. A replacement mechanism 3 is installed on one side of the support frame 1, and a multi-positioning mechanism 2 is installed on the other side of the support frame 1. The multi-positioning mechanism 2 includes a moving plate 21. A laser marker 24 is fixedly connected to one end of the moving plate 21. A connecting plate 29 is fixedly connected to one side of the moving plate 21. A positioning rod 28 is rotatably connected to one end of the connecting plate 29. A steering plate 27 is fixedly connected to one end of the positioning rod 28. A positioning block 26 is fixedly connected to one end of the steering plate 27. A first electric push rod 210 is rotatably connected to the other end of the steering plate 27. One end of the first electric push rod 210 is rotatably connected to one side of the moving plate 21. A threaded sleeve 211 is rotatably connected to the inner side of the moving plate 21. A threaded rod 23 is threadedly connected to the middle of the threaded sleeve 211. Fixing blocks 25 are fixedly connected to both ends of the threaded rod 23. One end of the fixing block 25 is fixedly connected to one side of the support frame 1. A steering handle 212 is fixedly connected to one end of the threaded sleeve 211.

[0024] Rotating the steering handle 212 causes the threaded sleeve 211 to rotate around its own axis. Since both ends of the threaded rod 23 are fixed to the support frame 1 by the fixing blocks 25, the threaded engagement between the threaded sleeve 211 and the threaded rod 23 converts the rotational motion into the axial linear motion of the moving plate 21. Adjusting the left and right positions of the moving plate 21 causes the inner side of the moving plate 21 to engage with both the threaded rod 23 and the guide rod 22. When the moving plate 21 moves along the threaded rod 23, the guide rod 22 restricts its rotational freedom, ensuring that the moving plate 21 only performs linear motion. The laser marker 24 is fixed. Fixed on the movable plate 21, the laser marker 24 moves synchronously with the movable plate 21, emitting a red laser beam that is projected onto the end of the paper core to form a clear positioning reference line. The paper core is quickly aligned by the laser line, ensuring that the end of the paper core is perpendicular to the axis of the take-up shaft. At the same time, the first electric push rod 210 works, pushing the steering plate 27 to swing around the positioning rod 28. The swing of the steering plate 27 causes the positioning block 26 to move closer to or away from the paper core, so that the positioning block 26 fits against the end of the paper core. Through the dual cooperation of laser positioning and mechanical positioning, the accuracy of paper core positioning is improved.

[0025] Example 2: Figure 1 and Figure 4 As shown, a guide rod 22 is slidably connected to one side of the movable plate 21, and the end of the guide rod 22 is fixedly connected to the inner side of the support frame 1; the replacement mechanism 3 includes a fixed plate 31, a positioning block 33 is rotatably connected to one end of the fixed plate 31, and a sleeve rod 34 is installed on the connection side between the positioning block 33 and the fixed plate 31; a push block 35 is fixedly connected to the other side of the positioning block 33, and a second electric push rod 32 is rotatably connected to one end of the push block 35, and one end of the second electric push rod 32 is rotatably connected to one side of the fixed plate 31.

[0026] When the second electric push rod 32 is working, it pushes the block 35 to move, causing the positioning block 33 to rotate around the hinge point of the fixed plate 31. The rotation of the positioning block 33 is transmitted to the slot through the sleeve rod 34. When the second electric push rod 32 extends, the positioning block 33 clamps the sleeve rod 34. When the second electric push rod 32 retracts, the positioning block 33 is released, making it easy to quickly remove the wound paper core roll. After installing a new paper core roll, the second electric push rod 32 extends, and the positioning block 33 clamps again, completing the roll change.

[0027] The usage and working principle of this device are as follows: When the second electric push rod 32 is working, it pushes the block 35 to move, causing the positioning block 33 to rotate around the hinge point of the fixed plate 31. When the second electric push rod 32 extends, the positioning block 33 clamps the sleeve rod 34. When the second electric push rod 32 retracts, the positioning block 33 releases, completing the roll change. Rotating the steering handle 212 drives the threaded sleeve 211 to rotate, adjusting the left and right positions of the moving plate 21. The laser marker 24 is fixed on the moving plate 21 and moves synchronously with the moving plate 21. The laser marker 24 emits a red laser beam, which is projected onto the end of the paper core to ensure that the end of the paper core is perpendicular to the axis of the take-up shaft. At the same time, the first electric push rod 210 is working, pushing the steering plate 27 to swing around the positioning rod 28, so that the positioning block 26 fits against the end of the paper core to position the paper core.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
