Description

Technical Field

[0001] The utility model relates to the technical field of slitting waste edge winding, in particular to a slitting waste edge winding device. Background Technique

[0002] A slitter is a mechanical device that slits wide-width paper, mica tape or film into multiple narrow-width materials, and is commonly used in papermaking machinery, wire and cable mica tape, and printing and packaging machinery. The main applications of the slitter are: non-woven fabric; slitting of mica tape, paper, insulating materials and various film materials, especially suitable for slitting of narrow tapes. The waste edges on both sides are wound separately by a winding device. The patent with the publication number CN220811242U discloses a slitting waste edge winding device with self-adaptive speed for a slitter, which solves the problems that after the existing device winds the waste materials, it is inconvenient to remove the waste material winding shaft and replace it with a new one to continue the operation, and as the winding thickness of the waste edge increases, it cannot be evenly distributed on the winding shaft, and the waste edge is led to deviate from the film on the trimming machine, generating a pulling force on the film on the trimming machine, thus affecting the normal operation of the trimming machine. However, during the waste edge winding process, as the winding thickness of the waste roll increases, the winding linear speed becomes larger and larger, which is likely to have a pulling force on the slitting gap, thus easily affecting the slitting effect. Therefore, a slitting waste edge winding device is designed to facilitate the winding traction to be consistent with the slitting speed, avoid the problem that the slitting gap is pulled due to the inconsistency with the slitting speed, resulting in an uneven slitting seam, and further improve the slitting stability.

An elastic cover 14 is arranged between the pressure roller strips 13 and the fixed shafts 12. An elastic member is arranged in the elastic cover 14, and the pressure roller strips 13 can be kept vertical to the traction roller 7 through the elastic member. A guide ring 15 facing the guide assembly and slidingly cooperating with the pressure roller strips 13 is arranged on the outside of the ring cover 11. The guide ring 15 is fixedly connected to the side plate 1. Furthermore, the elastic member can be set as a torsion spring or a pull ring, and a torsion spring is preferably used.

[0030] Specifically, a tension adjustment mechanism is provided between the waste edge traction mechanism and the winding mechanism, and the tension adjustment mechanism is electrically connected to the winding mechanism. By providing the tension adjustment mechanism, the waste edge before being wound onto the winding mechanism can be kept in a stretched state, thereby preventing the waste edge wound onto the winding mechanism from becoming loose and preventing excessive winding from causing pulling on the waste edge traction mechanism, thereby improving the stability of the winding.

[0031] Specifically, the winding mechanism includes a waste edge winding roller 10 rotatably connected to the frame, a winding drive motor 23 is fixedly installed on the frame, and the winding drive motor 23 is connected to the winding drive motor 23 through a driving transmission assembly 24. The tension adjustment mechanism includes a fixed frame 16 fixedly installed on the frame, a fixed rod 17 is slidably matched on the fixed frame 16, and a U-shaped frame 18 rotatably connected to a tension pressure roller 19 is fixedly installed on one end of the fixed rod 17, a guide slide bar 22 that is slidably matched with the fixed frame 16 is fixedly installed on the U-shaped frame 18, and an annular pressure detector 21 is fixedly installed on the fixed frame 16, and the annular pressure detector 21 and the U-shaped frame 18 are connected by The compression spring 20 is fixedly connected, and the annular pressure detector 21 is electrically connected to the winding drive motor 23. When the pressure detected by the annular pressure detector 21 becomes smaller, and the compression force of the compression spring 20 is reduced to a certain value, a signal is transmitted to the winding drive motor 23, and the winding drive motor 23 starts to drive the waste edge winding roller 10 to rotate, and then drives the winding. When the pressure of the annular pressure detector 21 increases to a certain value, a signal is transmitted to the winding drive motor 23, so that the winding drive motor 23 is turned off and the winding is stopped. Furthermore, the drive transmission component 24 and the synchronous transmission component 25 can both be set to a transmission mode of a sprocket chain and a synchronous wheel and synchronous belt.

[0032] Specifically, the guiding assembly includes two guiding rollers 8 arranged at the upper and lower positions on the left side of the traction roller 7. Through the two guiding rollers 8, it is convenient to guide the waste edge bypassing the traction roller 7 so that it is close to the traction roller 7 by no less than 180 degrees. Further,...

[0033] Specifically, it also includes a set of tension guiding rollers 9 located directly below the two guiding rollers 8. The tension pressing roller 19 is located between the tension guiding roller 9 and the lowermost guiding roller 8. By setting the tension guiding roller 9, it is convenient to cooperate with the lowermost guiding roller 8, which is convenient for guiding the waste edge and increasing the stability of the waste edge tension adjustment of the tension adjustment mechanism.

[0034] Specifically, the slitting mechanism further includes a mounting frame fixedly installed on the frame. A U-shaped frame 18 is slidably fitted up and down through a driving cylinder on the mounting frame. The slitting roller 4 is rotatably connected to the U-shaped frame 18. Further, it is convenient to adjust the overall height of the U-shaped frame 18 and the slitting roller 4 through the driving cylinder, thereby facilitating the winding of the coil material between the slitting auxiliary roller 3 and the slitting roller 4.

[0035] Specifically, the slitting mechanism further includes a first slitting guiding roller 5 and a second slitting guiding roller 6 respectively arranged on both sides of the slitting auxiliary roller 3. The first slitting guiding roller 5 and the second slitting guiding roller 6 are rotatably connected to the frame. The first slitting guiding roller 5 is located below the slitting auxiliary roller 3, and the second slitting guiding roller 6 is at the same height as the first slitting guiding roller 5. It is convenient to guide the coil material before and after slitting through the slitting auxiliary roller 3 and the second slitting guiding roller 6.

[0036] Specifically, the frame includes two groups of symmetrically arranged side plates 1. The two side plates 1 are fixedly connected by a plurality of connecting rods 2. Further, one of the groups of side plates 1 may also include a driving motor for driving the rotation of the slitting auxiliary roller 3 or the traction roller 7. It is convenient to drive the start of the slitting mechanism and the waste edge traction mechanism through the driving motor.

[0037] During use, wind one end of the coil material between the slitting auxiliary roller 3 and the slitting roller 4, and sequentially wind the removed waste edge around the waste edge traction mechanism and then wind it onto the winding mechanism. As the slitting progresses, the slitting auxiliary roller 3 and the traction roller 7 maintain the same speed, so that the waste edge traction speed is consistent with the slitting speed. When the pressing roller bar 13 rotates to the top, under the guiding action of the guiding ring 15, the pressing roller bar 13 bends downward to press the waste edge tightly against the traction roller 7, and then when it rotates to the bottom, the pressing roller bar 13 opens under the action of the elastic member. In this way, it can be ensured that the two pressing roller bars 13 cross to traction the waste edge continuously, and the traction waste edge is wound by the winding mechanism.
