Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a limiting device. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] A ring spinning frame is a device used in the spinning process to draft, twist, and wind roving or sliver into fine yarn bobbins. It is a core machine in the spinning process and is now widely used. In existing technology, the pressure on the ring spinning frame's cradle in a semi-unloaded state can easily cause indentations and damage to the rollers. Furthermore, during long maintenance periods or when starting or stopping the equipment, lifting the cradle can easily lead to yarn breakage, affecting the yarn retention rate during startup. Therefore, how to design a limiting device to effectively limit the cradle of the ring spinning frame and ensure that it does not adversely affect the rollers or other related structures has become a problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a limiting device that reduces the adverse effects of the cradle on related structures.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a limiting device, comprising:

[0006] A hook assembly, disposed between the rocking position and the fixed position of the cradle, includes:

[0007] Upper hook body, the upper hook body being used to hook onto the rocking position of the cradle;

[0008] The lower hook body is located at the bottom of the upper hook body and is used to hook onto the fixed position of the cradle.

[0009] Adjustment component, used to adjust the distance between the upper and lower hooks.

[0010] Furthermore, the hook assembly also includes a sliding piece disposed at the bottom of the upper hook body, and the lower hook body has a sliding groove that slides in cooperation with the sliding piece;

[0011] The bottom of the sliding plate and the top of the lower hook are respectively provided with a first adjusting plate and a second adjusting plate. The adjusting assembly includes a threaded rod rotatably disposed on the second adjusting plate, and the threaded rod is screwed into the second adjusting plate.

[0012] Furthermore, a limiting component is rotatably provided on the side of the upper hook away from the lower hook, and the limiting component can close the hook opening after the upper hook is hooked into the rocking position of the cradle.

[0013] Furthermore, a wave-shaped locking groove is provided on the side of the upper hook body near the limiting component. The limiting component includes a sleeve plate that is rotatably mounted on the upper hook body. An abutment plate is slidably mounted inside the sleeve plate. The sleeve plate can drive the abutment plate to rotate until it abuts against the recess of the locking groove. A locking component is provided on the sleeve plate to limit the abutment plate when it slides to the corresponding position inside the sleeve plate.

[0014] Furthermore, the abutment plate has multiple locking holes inside, and the locking assembly includes a pin that is slidably mounted on the sleeve plate. A spring is provided inside the sleeve plate to press the pin and insert it into the corresponding locking hole. An adjusting rod is provided at the end of the pin away from the locking hole, extending through the sleeve plate.

[0015] The beneficial effects of this utility model are reflected in:

[0016] In this invention, by hooking the upper hook and the lower hook to the rocking position and the fixed position of the cradle respectively, and matching the distance between the upper hook and the lower hook with the pressure of the cradle in the semi-unloaded state, the rocking position of the cradle is effectively limited. This method can ensure that the indentation and damage to the rollers are reduced during long periods of shutdown, while also maximizing the yarn head retention rate when restarting. This method can effectively ensure the yarn head retention rate when restarting the spinning machine after several days of shutdown, thus facilitating practical use. Attached Figure Description

[0023] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. 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 scope of protection of the present utility model.

[0024] Please see Figure 1-4 This utility model discloses a limiting device, including a hook assembly 1, which is disposed between the rocking position and the fixed position of the rocker arm. The hook assembly 1 includes an upper hook body 11 and a lower hook body 13 disposed at the bottom of the upper hook body 11. The upper hook body 11 is used to hook onto the rocking position of the rocker arm, and the lower hook body 13 is used to hook onto the fixed position of the rocker arm. In addition, the hook assembly 1 is also provided with an adjustment component, which is used to adjust the distance between the upper hook body 11 and the lower hook body 13.

[0025] In practice, by hooking the upper hook 11 and the lower hook 13 to the rocking position and the fixed position of the cradle respectively, and matching the distance between the upper hook 11 and the lower hook 13 with the pressure of the cradle in the semi-unloaded state, the rocking position of the cradle is effectively limited. This method can ensure that the indentation and damage to the rollers are reduced during long periods of shutdown, while also maximizing the yarn head retention rate when restarting. This method can effectively ensure the yarn head retention rate when restarting the spinning machine after several days of shutdown, thus facilitating practical use.

[0026] In one embodiment, the hook assembly 1 further includes a sliding piece 12 installed at the bottom of the upper hook body 11, and a sliding groove on the lower hook body 13 that slides with the sliding piece 12. A first adjusting piece 14 and a second adjusting piece 15 are respectively installed at the bottom of the sliding piece 12 and the top of the lower hook body 13. The first adjusting piece 14 and the second adjusting piece 15 are both located on the side of each hook body away from its hook opening. The adjusting assembly includes a threaded rod 2 rotatably installed on the second adjusting piece 15, and the threaded rod 2 is screwed into the second adjusting piece 15.

[0027] In practice, the distance between the upper hook body 11 and the lower hook body 13 can be changed by rotating the threaded rod 2. This design makes it easy to hook the upper hook body 11 and the lower hook body 13 into the rocking position and the fixed position of the cradle. After installation, the threaded rod 2 can be rotated to adjust the distance between the upper hook body 11 and the lower hook body 13, so that it can be adapted to different spinning machines.

[0028] In one embodiment, a limiting component 3 is rotatably provided on the side of the upper hook 11 away from the lower hook 13. The limiting component 3 can close the hook opening of the upper hook 11 after it is hooked into the rocking position of the cradle, thereby preventing the rocking position of the cradle from disengaging from the hook opening of the upper hook 11.

[0029] In one embodiment, the upper hook 11 has a wave-shaped locking groove 16 on the side near the limiting component 3. Specifically, the locking groove 16 can be formed by multiple triangular grooves arranged vertically to form a wave-shaped locking groove 16. The limiting component 3 includes a sleeve 31 that is rotatably mounted on the upper hook 11. An abutment plate 32 is slidably disposed inside the sleeve 31. A locking component 4 is disposed on the sleeve 31. The locking component 4 is used to limit the abutment plate 32 when it slides to the corresponding position inside the sleeve 31.

[0030] In practice, the sleeve plate 31 can drive the abutment plate 32 to rotate until it abuts against the inner recess of the locking groove 16. In conjunction with the locking component 4, the adjusted abutment plate 32 is limited, so that the limiting component 3 can abut against the locking groove 16 very stably, thereby ensuring that the rocking position of the rocker is difficult to disengage.

[0031] In one embodiment, the abutment plate 32 has a plurality of locking holes 33 inside, and the locking assembly 4 includes a pin 41 slidably mounted on the sleeve plate 31. A spring 43 is installed inside the sleeve plate 31. The spring 43 is used to press the pin 41 and insert the pin 41 into the corresponding locking hole 33. An adjusting rod 42 is provided at the end of the pin 41 away from the locking hole 33, which extends through the sleeve plate 31.

[0032] In practice, by pulling the adjusting rod 42 away from the abutment plate 32, the abutment plate 32 can be slid until the corresponding locking hole 33 is aligned with the adjusting rod 42. After alignment, the adjusting rod 42 is released, and the spring 43 will squeeze the pin 41, so that the pin 41 is inserted into the corresponding locking hole 33, thereby determining the combined length of the sleeve plate 31 and the abutment plate 32. Finally, it is abutted against the corresponding position of the locking groove 16. This method can effectively adjust the size of the hook opening of the upper hook body 11 after it is closed, so it can be adapted to various spinning machine cradles.
