Description

Technical Field

[0001] This utility model relates to the technical field of textile machinery, and in particular to an adjustment device for a yarn storage device. Background Technology

[0002] A yarn storage device is a device used in textile machinery for storing and supplying yarn. It typically includes a machine body, a yarn storage cylinder, and a motor. The yarn storage cylinder is rotatably mounted on one side of the machine body. The motor drives the yarn storage cylinder to rotate, thereby winding the yarn onto the yarn storage cylinder for yarn storage.

[0003] The yarn storage cylinder is fitted with a yarn pressing ring, and a swing block is located on the side of the machine body facing the yarn pressing ring. The swing block is connected to the yarn pressing ring. A lever is located on the side of the swing block away from the yarn pressing ring. The lever extends into the machine body, and a fixed post protrudes from the machine body. A tension spring connects the fixed post and the lever. A switch device is located on the side of the lever away from the tension spring.

[0004] Initially, the yarn pressing ring is tilted relative to the yarn storage cylinder, and the tension spring pulls the actuating lever to tilt towards the side closer to the fixed rod. As the motor rotates, it drives the yarn storage cylinder to rotate, and the yarn continuously accumulates on the cylinder. This causes the yarn pressing ring to move upward and change its tilt angle, thereby driving the oscillating block to swing. This causes the actuating lever to approach the switching device until the switching device is triggered, at which point the motor stops rotating, and yarn storage stops.

[0005] In existing yarn feeders, the two ends of the tension spring are fixed to the actuating rod and the fixing rod. Without replacing the tension spring, the spring constant is fixed, and the tension of the tension spring on the actuating rod cannot be adjusted, thus the pressure of the yarn presser ring on the yarn cannot be adjusted. Therefore, it is necessary to design an adjustable tension spring tension adjustment device. In addition, how to conveniently and accurately adjust the tension spring tension is also a technical problem that needs to be solved. Summary of the Invention

[0006] The purpose of this invention is to provide an adjustment device for a yarn storage device, which can not only adjust the pressure of the yarn pressing ring on the yarn by adjusting the tension of the tension spring, but also fine-tune the tension of the tension spring by adjusting the control panel, and the adjustment is more convenient and precise.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustment device for a yarn storage device, the yarn storage device including a machine body, a yarn storage cylinder rotatably connected to the machine body, and a motor driving the yarn storage cylinder to rotate, the yarn storage cylinder is provided with a yarn pressing ring, the yarn pressing ring is provided with a swing block, the adjustment device includes a lever, a tension spring, a rotating shaft, and a control disk, the lower end of the lever is connected to the swing block, the upper end of the lever extends into the machine body, the machine body is provided with a channel for the lever to swing, the rotating shaft is rotatably installed in the machine body, the rotating shaft is provided with a hanging part that rotates synchronously with it, one end of the tension spring is connected to the hanging part, the other end of the tension spring is connected to the lever, the control disk is rotatably installed on the upper end of the machine body, the control disk is provided with an internal gear ring, the rotating shaft is provided with a gear part that meshes with the internal gear ring, when the control disk rotates, the internal gear ring and the gear part cooperate to drive the rotating shaft to rotate, thereby adjusting the tension of the tension spring.

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] like Figures 1-10 As shown, an adjustment device for a yarn storage device is disclosed. The yarn storage device includes a machine body 10, a yarn storage cylinder 20 rotatably connected to the machine body 10, and a motor for driving the yarn storage cylinder 20 to rotate. The yarn storage cylinder 20 is provided with a yarn pressing ring 30, and the yarn pressing ring 30 is provided with a swing block 40. The two ends of the swing block 40 are respectively pivotally connected to the lower end of the machine body 10 by pins. A bearing seat is provided at the center of the lower end of the swing block 40. The yarn pressing ring 30 is rotatably connected to the bearing seat through the bearing. The connection structure between the yarn pressing ring 30 and the swing block 40 is prior art and will not be described in detail in this application.

[0034] The adjusting device 50 includes a lever 51, a tension spring 52, a rotating shaft 53, and a control panel 54. The lower end of the lever 51 is connected to the swing block 40, and the upper end of the lever 51 extends into the body 10. The body 10 is provided with a channel 11 for the lever 51 to swing. The rotating shaft 53 is rotatably installed inside the body 10 and is provided with a hanging part 55 that rotates synchronously with it. One end of the tension spring 52 is connected to the hanging part 55, and the other end of the tension spring 52 is connected to the lever 51. The control panel 54 is rotatably installed. At the upper end of the machine body 10, the control disk 54 is provided with an internal gear ring 541, and the rotating shaft 53 is provided with a gear part 531 that meshes with the internal gear ring 541. When the control disk 54 rotates, the internal gear ring 541 and the gear part 531 work together to drive the rotating shaft 53 to rotate, so that the hanging part 55 rotates around the axis of the rotating shaft 53, thereby adjusting the tension of the tension spring 52. After the tension of the tension spring 52 is adjusted, it can drag the lever 51, causing the swing block 40 to rotate slightly, thereby causing the pressure ring 30 to rotate at a certain angle. Because the internal gear ring 541 has a large number of teeth, it is possible to fine-tune the tension of the tension spring 52.

[0035] The adjusting device 50 of the yarn storage device of this utility model can not only adjust the pressure of the yarn pressing ring 30 on the yarn by adjusting the tension of the tension spring 52, but also fine adjust the tension of the tension spring 52 by the control panel 54, and the adjustment is relatively convenient and precise.

[0036] In some embodiments, a rotating ring 56 is sleeved on the outer periphery of the rotating shaft 53 or radially protruding therefrom, and a hanging part 55 is fixedly disposed on the outer periphery of the rotating ring 56. The axis of the rotating shaft 53 and the center of the rotating ring 56 are not in the same position. When the rotating shaft 53 rotates, the hanging part 55 rotates around the axis of the rotating shaft 53, thereby stretching the tension spring 52 to adjust the tension of the tension spring 52.

[0037] In some embodiments, the circumference of the rotating ring 56 is provided with a concave arc surface 561, which supports the tension spring 52. When the tension spring 52 rotates around the rotating ring 56, the arc surface 561 supports the tension spring 52. Further, the rotating ring 56 has an upper plate portion 562 and a lower plate portion 563, the arc surface 561 is disposed between the upper plate portion 562 and the lower plate portion 563, and the hanging portion 55 is a connecting post connecting the upper plate portion 562 and the lower plate portion 563.

[0038] In some embodiments, the end of the tension spring 52 connected to the hanging part 55 and the end connected to the lever 51 are in the same height range. This arrangement allows the hanging part 55 to drive the tension spring 52 to rotate around the arc surface 561, thereby improving the service life of the tension spring 52.

[0039] In some embodiments, the outer periphery of the control panel 54 is provided with an elastic groove 5421, and the body 10 is provided with a retaining ring 12 that engages with the elastic groove 5421. The engagement between the elastic groove 5421 and the retaining ring 12 limits the control panel 54 along the axial direction, thereby preventing the control panel 54 from detaching from the body 10. Specifically, the lower end of the control panel 54 is provided with a plurality of elastic feet 542, each elastic foot 542 having a limiting surface 5423. An elastic groove 5421 is formed between the limiting surface 5423 and the lower end of the control panel 54, and each elastic foot 542 has a guide slope 5422 for easy insertion into the retaining ring 12.

[0040] In some embodiments, the surface of the control panel 54 is provided with anti-slip texture 543 for easy twisting. The anti-slip texture 543 facilitates the user to twist the control panel 54 and also facilitates the user to control the rotation angle of the control panel 54.

[0041] In some embodiments, the rotating shaft 53 is disposed on the side of the body 10, and the gear part 531 is disposed on the upper end of the rotating shaft 53 and meshes with the internal gear ring 541. The purpose of this arrangement is to minimize the size of the gear part 531 and effectively prevent the body 10 from becoming bulky.

[0042] In some embodiments, the body 10 is provided with a limiting post 13, and the rotating ring 56 is provided with an arc-shaped groove 564 centered on the axis of the rotating shaft 53. The limiting post 13 extends into the arc-shaped groove 564 and cooperates with the arc-shaped groove 564 to limit the rotation angle of the rotating shaft 53. That is, the rotation stroke is limited by the cooperation between the limiting post 13 and the arc-shaped groove 564, which is used to prevent the tension spring 52 from being deformed or broken.

[0043] In some embodiments, a braking assembly 60 is provided within the body 10. The braking assembly 60 restricts the rotation of the internal gear ring 541 or the gear portion 531, thereby restricting the return of the tension spring 52. Further, the braking assembly 60 includes a bracket 61 fixedly connected within the body 10 and an elastic hook 62 or protrusion 63 fixed to the bracket 61. When the elastic hook 62 is used, its hook body engages with the internal gear ring 541 or the gear portion 531 to limit rotation and prevent the tension spring 52 from returning. Similarly, when the protrusion 63 is used, its engagement with the internal gear ring 541 or the gear portion 531 restricts rotation and prevents the tension spring 52 from returning. Furthermore, the protrusion 63 is an arc-shaped protrusion 63. The adjustment device 50 of the yarn storage device of this utility model, through the setting of the braking component 60, can effectively prevent the operator from accidentally operating the control panel 54, and at the same time can limit the rebound of the tension spring 52.

[0044] In other embodiments, the braking assembly 60 includes a pawl rotatably connected to the body 10 and an elastic element that presses the pawl against the internal gear ring 541.

[0045] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
