Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and more specifically, it relates to an internal support mechanism for winding. Background Technology

[0002] The winding machine is one of the essential pieces of equipment in the post-spinning and preparation process. It is mainly used to wind yarn into cones. By processing the bobbins or skeins from the spinning department into cones that meet certain requirements on the winding machine, the production process of cones requires placing the bobbins onto the rotating shaft of the winding machine. The rotating shaft drives the bobbins to rotate, thus completing the purpose of winding the yarn and forming cones.

[0003] The existing winding machine has three support blocks at both the upper and lower ends of the rotating shaft, which slide and engage with the rotating shaft. A spring is installed between the support blocks and the rotating shaft. When processing packaged yarn, the packaged yarn needs to be placed on the rotating shaft, and the support blocks abut against the inner wall of the package to limit the movement of the package and drive it to rotate. However, the contact area between the support blocks and the inner wall of the package on the existing rotating shaft is small, and the force exerted on the inner wall of the package comes from the elastic force of the spring. This can lead to deviations in the force exerted by each support block on the inner wall of the package. As a result, when the rotating shaft rotates at high speed, it not only generates a lot of noise, but also causes the packaged yarn to shake a lot, which causes significant damage to both the packaged yarn and the rotating shaft, affecting the service life of both the rotating shaft and the packaged yarn.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide an inner support mechanism for winding cylinders in order to solve the above-mentioned problems.

[0006] The above-mentioned technical objective of this utility model embodiment is achieved through the following technical solution: an inner support block for winding cylinder, including a connecting block and a plurality of expansion plates, wherein the plurality of expansion plates are arranged in a circumferential array and the expansion plates are fixedly connected to one end of the connecting block, and the expansion plates are provided with interconnected second slots, wherein a spring coil is engaged in the second slot.

[0007] The present invention is further configured such that: a guide surface is provided at the end of the expansion plate away from the connecting block, a groove is provided at the upper end of the connecting block, and a second limiting groove is formed between the connecting block and the expansion plate.

[0008] The present invention is further configured as follows: a winding inner support mechanism, including a mounting base and a rotating shaft that rotatably engages with the mounting base, two symmetrically distributed inner support blocks are slidably connected on the rotating shaft, a connecting rod is provided between the two inner support blocks, the connecting rod is engaged with a sink, a limiting block that abuts against the upper inner support block is fixedly connected to the upper end of the rotating shaft, and a spring-loaded device for driving the inner support blocks to move upward is slidably connected on the rotating shaft.

[0009] The present invention is further configured such that: the rebound device includes a support block that slides with the rotating shaft, the support block is provided with a first limiting groove, a spring is provided between the first limiting groove and the mounting base, and the spring is sleeved on the outside of the rotating shaft.

[0010] The present invention is further configured such that: the upper end of the support block is provided with a conical boss, the conical boss can abut against the guide surface after sliding, the limiting block includes a connecting column and a limiting conical platform for abutting against the guide surface, and the limiting block is fixed to the rotating shaft by a limiting screw.

[0011] The present invention is further configured such that: a first slot is provided on the rotating shaft, a limiting ring is engaged in the first slot, and a second limiting groove on the inner support block located below can abut against the limiting ring after sliding.

[0012] In summary, this utility model has the following beneficial effects:

[0013] By setting expansion plates, the contact area with the inner wall of the cylinder is greatly increased, resulting in greater friction between the inner support block and the inner wall of the cylinder. Multiple expansion plates are separated from each other by abutting against the limiting block or support block. At the same time, by setting spring coils, the spring coils can limit the multiple expansion plates and evenly distribute the force of the outer support, so that the force of the outer support of each expansion plate is equal. This makes the cylinder less prone to shaking during high-speed rotation, and gives both the inner support block and the cylinder a longer service life.

[0014] By setting two symmetrically distributed inner support blocks, when it is necessary to limit the cylinder using the inner support mechanism, the cylinder is sleeved outside the inner support mechanism, and the force on the spring-loaded device is released. The spring-loaded device will spring back upward, thereby applying force to the guide surface of the expansion plate, causing the two inner support blocks to move upward. The inner support block located above will be opened by the action of the limiting block, so that the ends of multiple expansion plates away from the connecting block move away from each other and abut against the inner wall of the upper end of the cylinder. The inner support block located below will also move away from each other by the action of the supporting block and abut against the inner wall of the lower end of the cylinder, thus limiting the cylinder.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In one possible embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, an inner support block and inner support mechanism for winding cylinders include a mounting base 1 and a rotating shaft 2 that rotatably engages with the mounting base 1. Two symmetrically distributed inner support blocks 3 are slidably connected on the rotating shaft 2. A connecting rod 4 is provided between the two inner support blocks 3. The inner support block 3 includes a connecting block 301 and multiple expansion plates 302. A groove 3011 is provided at the upper end of the connecting block 301. The connecting rod 4 is engaged with the groove 3011. Through the engagement of the connecting rod 4 with the groove 3011, the linkage between the two inner support blocks 3 is realized, that is, the upward movement of the lower inner support block 3 can drive the upper inner support block 3 to move.

[0024] For further details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, multiple expansion plates 302 are arranged in a circumferential array and are fixedly connected to the lower end of the connecting block 301. The upper end of the rotating shaft 2 is fixedly connected to a limiting block 5 that abuts against the upper inner support block 3. A spring-loaded device 6 is slidably connected to the rotating shaft 2 to drive the inner support block 3 to move upward. When it is necessary to limit the cylinder using the inner support mechanism, by sleeved on the inner support mechanism and releasing the force on the spring-loaded device, the spring-loaded device will spring upward, thereby applying force to the expansion plates 302 and driving the two inner support blocks 3 to move upward. The upper inner support block 3 will be opened by the action of the limiting block 5, so that the multiple expansion plates 302 are away from the connecting block. One end of each of the 301 blocks moves away from each other and abuts against the inner wall of the upper end of the cylinder. The inner support blocks 3 located below will also move away from each other under the action of the spring-loaded device 6 and abut against the inner wall of the lower end of the cylinder, thus limiting the cylinder. By setting the expansion plate 302, the contact area with the inner wall of the cylinder is greatly increased, so that the inner support block 3 and the inner wall of the cylinder generate a large friction force. Moreover, the multiple expansion plates 302 move away from each other by abutting against the limiting block 5 or the spring-loaded device 6, so that the force between each expansion plate 302 and the inner wall of the cylinder is equal, so that the cylinder is not easy to shake during high-speed rotation, and both the inner support block and the cylinder have a longer service life.

[0025] For further details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the rebound device 6 includes a support block 601 that slides with the rotating shaft 2. A first limiting groove 6011 is provided inside the support block 601. A spring 602 is provided between the first limiting groove 6011 and the mounting base 1. The spring 602 is sleeved on the outside of the rotating shaft 2. The force exerted by the spring 602 on the support block 601 causes the support block 601 to move upwards and abut against the inner support block 3. A guide surface 3021 is provided at the end of the expansion plate 302 away from the connecting block 301. A conical boss 6012 is provided at the upper end of the support block 601. After sliding, the conical boss 6012 can abut against the guide surface 3021. The limiting block 5 includes a connecting post 501 and a limiting cone 502 for abutting against the guide surface 3021. Through the abutment of the guide surface 3021 against the conical boss 6012 or the limiting cone 502, multiple expansion plates can be abutted. The mutual separation of 302 serves as a guide, achieving contact limitation between the expansion plate 302 and the inner wall of the cylinder. The limiting block 5 is fixed to the rotating shaft 2 by the limiting screw 7. After the limiting block 5 is sleeved on the rotating shaft 2, the limiting block 5 is fixed to the rotating shaft 2 by the limiting screw 7. The expansion plate 302 is provided with interconnected second slots 3022. A spring coil 9 is engaged in the second slot 3022. By setting the spring coil 9, the expansion plate 302 can be limited, preventing excessive deformation of the expansion plate 302. The spring coil 9 can also evenly distribute the external support force, making the external support force of each expansion plate 302 equal, thus making the force with the inner wall of the cylinder equal, so that the cylinder will not shake when it rotates during operation. In addition, the spring coil 602 can also help the expansion plate 302 contract, making the expansion plate 302 have a longer service life.

[0026] For further details, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a first slot 201 is provided on the rotating shaft 2, and a limiting ring 8 is engaged in the first slot 201. A second limiting groove 303 is formed between the connecting block 301 and the expansion plate 302. After the second limiting groove 303 slides, it can abut against the limiting ring 8. Then, when the bobbin needs to be removed, by applying force to the support block 601, the support block 601 moves downward, and the inner support block 3 moves downward together under the action of gravity, so that the upper inner support block 3 separates from the limiting protrusion, and the limiting groove of the lower inner support block 3 abuts against the limiting ring 8, realizing the separation of the lower inner support block 3 from the support block 601, causing multiple expansion plates 302 to contract, so that the processed bobbin yarn can be easily removed.
