Description

Technical Field

[0001] This utility model relates to the field of winding shaft technology, and in particular to a small-sized winding shaft for slitting machines. Background Technology

[0002] The slitting machine take-up reel is an important component of a slitting machine, mainly used to roll processed materials (such as paper, film, and fabric) into rolls. Its function is to divide wide-width materials into multiple strips as needed during the slitting process and wind them into individual rolls for easy storage, transportation, or further processing. Slitting machine take-up reels typically have the following characteristics.

[0003] Existing technologies, such as the utility model with publication number CN207175053U, specifically disclose a slitting machine for continuous slitting. In this machine, an unwinding shaft on the casing is used to mount the material to be slitted; a traction roller group is used to flatten and pull the material to be slitted, thereby increasing slitting stability; a cutting roller group is used to slit the material to be slitted; a take-up shaft is used to collect the slitted rolls; and a motor is used to drive the rotation of the unwinding shaft, traction roller group, cutting roller group, and take-up shaft respectively, so as to realize the slitting of the material to be slitted. A cooling device on the casing is used to cool the motor inside the casing, eliminating the need for the motor to stop for cooling after a period of operation, thereby increasing the continuous working time of the motor. This allows the slitting machine to continuously slit the material to be slitted for a long time, saving working time and improving slitting efficiency.

[0004] The following defects were found in the above: The traditional method of installing the take-up shaft and the drive shaft used to drive the rotation is to use bolts and screw holes for installation. However, the installation position is fixed. For films of different widths and different slitting widths, it is not easy to adjust the position of the take-up shaft to a suitable position, which causes inconvenience to the operator during the film winding process. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the traditional winding shaft and the drive shaft used for rotation are installed using bolts and screw holes, but the installation position is fixed. This makes it difficult to adjust the winding shaft position to a suitable location for films of different widths and different slitting widths, thus causing inconvenience to operators during the film winding process. Therefore, this invention proposes a small-sized winding shaft for slitting machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a small-sized take-up shaft for a slitting machine, comprising two bushings, an adjustment structure, and an auxiliary structure. The two bushings are connected by the auxiliary structure. A retaining ring is fixedly connected to the arc surface of each bushing. The adjustment structure is disposed on the bushing and includes a sliding hole. The sliding hole is opened on the arc surface of the bushing. A locking block is slidably connected to the inner wall of the sliding hole. The outer end of the locking block is inclined. The arc surface of the bushing is threaded. A rotating ring is threadedly connected to the threaded position of the bushing. The end of the rotating ring near the locking block is inclined. A retaining ring is fixedly connected to the arc surface of one end of the bushing.

[0007] The effect achieved by the above components is that the rotating ring can squeeze the locking block, causing the locking block to slide inward and squeeze onto the drive shaft that is fitted with the take-up shaft.

[0008] Preferably, a plurality of anti-slip strips are fixedly connected to the arc surface of the rotating ring, and the plurality of anti-slip strips are evenly distributed on the arc surface of the rotating ring.

[0009] The effect achieved by the above components is to increase the roughness of the circular arc surface of the rotating ring.

[0010] Preferably, a fixing plate is fixedly connected to one side of the card block, a spring is fixedly connected to the lower surface of the fixing plate, a fixing block is fixedly connected to the lower end of the spring, and the fixing block is fixedly connected to the bushing.

[0011] The effect achieved by the above components is that when the rotating ring disengages from the locking block, the locking block can be quickly rebounded by the elastic force of the spring.

[0012] Preferably, a limit rod is slidably provided inside the spring, the lower end of the limit rod is fixedly connected to the fixing block, and the upper end of the limit rod slides through the fixing plate.

[0013] The effect achieved by the above-mentioned components is that they allow the spring to extend and retract on the limiting rod, thereby limiting the direction of the spring force.

[0014] Preferably, the auxiliary structure includes an extension tube, one end of which is fixedly connected to a plurality of positioning blocks, and the other end of the extension tube is provided with a plurality of slots corresponding to the positions of the positioning blocks, wherein the size of the positioning blocks is adapted to the size of the slots of the extension tube.

[0015] The effect achieved by the above components is that the winding width can be adjusted when the cutting width is different.

[0016] Preferably, a plurality of positioning grooves are provided on one inner end of the bushing, the positioning grooves of the bushing correspond to the positions of the positioning blocks on the extension tube, and the size of the positioning grooves is adapted to the size of the positioning blocks on the extension tube.

[0017] The effect achieved by the above components is that after connecting several extension tubes end to end, the positioning block of the extension tube can be locked in the positioning groove of the bushing, which facilitates the connection.

[0018] In summary, the beneficial effects of this utility model are as follows:

[0019] In this invention, by setting an adjustment structure, the bushing can slide on the drive shaft. After sliding to a suitable position, the bushing can be locked and fixed, thereby achieving the effect of adaptive adjustment for different cutting positions. By setting an auxiliary structure, the distance between the two bushings can be adjusted according to different cutting widths, thereby adjusting the winding width of the bushing.

[0027] Reference Figure 1 As shown, this utility model provides a technical solution: a small-sized take-up shaft for a slitting machine, including two bushings 1, an adjustment structure 2 and an auxiliary structure 3. The two bushings 1 are connected by the auxiliary structure 3. A retaining ring 4 is fixedly connected to the arc surface of the bushing 1. The adjustment structure 2 is set on the bushing 1.

[0028] The specific settings and functions of its adjustment structure 2 and auxiliary structure 3 will be explained below.

[0029] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in this embodiment: the adjusting structure 2 includes a sliding hole 201, which is formed on the arc surface of the bushing 1. A locking block 202 is slidably connected to the inner wall of the sliding hole 201. The outer end of the locking block 202 is inclined. The arc surface of the bushing 1 is threaded. A rotating ring 203 is threadedly connected to the position where the bushing 1 is threaded. The end of the rotating ring 203 near the locking block 202 is inclined. A locking ring 204 is fixedly connected to the arc surface of one end of the bushing 1. The rotating ring 203 can be rotated to squeeze the locking block 202, causing the locking block 202 to slide inward. The locking block 202 then presses against the drive shaft that is fitted with the take-up shaft. Several anti-slip strips 205 are fixedly connected to the arc surface of the rotating ring 203. The several anti-slip strips 205 are evenly distributed on the arc surface of the rotating ring 203, thereby increasing the roughness of the arc surface of the rotating ring 203. A fixing plate 206 is fixedly connected to one side of the locking block 202. A spring 207 is fixedly connected to the lower surface of the fixing plate 206. A fixing block 210 is fixedly connected to the lower end of the spring 207. The fixing block 210 is fixedly connected to the bushing 1. This achieves the effect that when the rotating ring 203 disengages from the locking block 202, the spring force of the locking block 207 can be used to make the locking block 202 quickly rebound. A limit rod 208 is slidably provided inside the spring 207. The lower end of the limit rod 208 is fixedly connected to the fixing block 210, and the upper end of the limit rod 208 slides through the fixing plate 206. This achieves the effect of allowing the spring 207 to extend and retract on the limit rod 208, thereby limiting the direction of the spring force of the spring 207.

[0030] Reference Figure 6 As shown in this embodiment: the auxiliary structure 3 includes an extension tube 31, one end of which is fixedly connected to several positioning blocks 32, and the other end of the extension tube 31 has several slots 33 corresponding to the positions of the positioning blocks 32. The size of the positioning blocks 32 is adapted to the size of the slots 33 of the extension tube 31, which allows for adjustment of the winding width when cutting to different widths. The inner side of the bushing 1 has several positioning grooves 209, which correspond to the positions of the positioning blocks 32 of the extension tube 31, and the size of the positioning grooves 209 is adapted to the size of the positioning blocks 32 on the extension tube 31. This achieves the effect of connecting several extension tubes 31 end-to-end, allowing the positioning blocks 32 of the extension tubes 31 to be engaged in the positioning grooves 209 of the bushing 1 for easy connection.

[0031] Working principle: When the bushing 1 needs to be installed on the drive shaft used to drive the bushing 1 to rotate, first slide the bushing 1 onto the drive shaft, then slide an appropriate number of extension tubes 31 onto the drive shaft in a head-to-tail arrangement according to the cutting width requirements, and then put another bushing 1 onto the drive shaft. At this time, the positioning block 32 and the slot 33 of the adjacent extension tubes 31 are connected. The positioning block 32 at one end of the extension tube 31 can also be connected to the positioning slot 209 of the bushing 1. The other end can be fixed together by the locking and pressing method of the adjustment structure 2.

[0032] Then slide the bushing 1. When the bushing 1 is slid to the appropriate position, rotate the rotating ring 203. The rotating ring 203 rotates and begins to move towards the locking block 202 with the help of the thread. At this time, the rotating ring 203 begins to squeeze the locking block 202, so that several locking blocks 202 move inward and squeeze onto the drive shaft, thereby achieving the effect of fixing the position of the bushing 1. At this time, the film can be directly wound up.

[0033] After winding is completed, rotate the swivel 203 in the opposite direction to move the swivel 203 away from the locking block 202. At this time, the spring 207 will give the fixing plate 206 and the locking block 202 an upward elastic force, causing the locking block 202 to expand outward. At this time, the bushing 1 and the extension tube 31 can be removed from the drive shaft in sequence.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
