Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a combing roller needle cup. Background Art

[0002] In traditional textile machinery, the connection between the opening roller needle cup and the needle body mostly adopts a threaded connection structure, that is, the needle body is fixed and installed by cooperating with the threaded hole inside the needle cup through its own threaded end, such as a opening roller needle ring for air-jet spinning disclosed in application No. 2021217578349. However, this connection method has some inherent limitations and technical difficulties:

[0003] 1. The needle body is prone to wear and damage due to the long-term high-speed rotation and friction and impact during the fiber combing process. The threaded part is particularly fragile. Frequent wear will cause the thread cooperation between the needle body and the needle cup to fail, affecting the overall stability and service life.

[0004] 2. After a period of use, threaded connections often become stuck due to the accumulation of fiber debris, grease and other substances, which not only increases the difficulty of maintenance, but also greatly reduces the efficiency of disassembly and assembly of the needle body, which is not conducive to the rapid maintenance and replacement of the equipment.

[0005] 3. When the damaged needle body needs to be replaced, the operator often needs greater force and delicate operation to successfully disassemble the threaded needle body, which not only wastes working time, but may also lead to additional labor costs and risks of misoperation.

[0006] In view of the above problems existing in the prior art, the present invention aims to provide a combing roller needle cup that is easy to disassemble and assemble. Utility Model Content

[0007] In view of the deficiencies in the background technology, the utility model provides a combing roller needle cup.

[0008] The technical solution adopted by the utility model is: a combing roller needle cup, including a cup body and a needle body arranged in a connecting hole of the cup body, and also including a lifting spring and a top plate, one end of the lifting spring is connected to the bottom wall of the connecting hole, and the other end is connected to the top plate, connecting lugs are provided on both sides of the bottom of the needle body, and sliding grooves that slide with the connecting lugs are provided on the inner walls on both sides of the connecting hole, and an expansion ring groove that accommodates and allows the connecting lug to rotate is provided at the bottom of the connecting hole.

[0009] Furthermore, a positioning hole is provided on the upper wall of the ring expansion groove, and a positioning column capable of being inserted into the positioning hole is provided on the connecting lug.

[0010] Furthermore, the positioning hole and the positioning column are both conical structures.

[0011] Furthermore, a spring hole is provided at the bottom of the connecting hole, and the lifting spring is fixedly connected to the bottom wall of the spring hole.

[0012] The beneficial effects of the utility model are as follows: the application adopts a unique structural design of connecting lugs, slide slots, lifting springs and top plates, abandons the original threaded connection method, and greatly simplifies the installation and removal steps of the needle body. The operator only needs to align the connecting lug of the needle body with the slide slot and then rotate the needle body to connect the connecting lug to the slide slot. At the same time, the elastic force of the lifting spring and the top plate can be used to easily fix and position the needle body. Conversely, disassembly can also be completed quickly and easily, which greatly improves work efficiency and reduces manual labor intensity.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] The utility model provides a combing roller needle cup.

[0022] In this embodiment, refer to Figure 1-3 The combing roller needle cup includes a cup body 1 and a needle body 3 arranged in a connecting hole 2 of the cup body, and also includes a lifting spring 4 and a top plate 5. One end of the lifting spring is connected to the bottom wall of the connecting hole, and the other end is connected to the top plate. Connecting lugs 6 are provided on both sides of the bottom of the needle body, and sliding grooves 7 that slide with the connecting lugs are provided on the inner walls on both sides of the connecting hole, and an expansion ring groove 8 that accommodates and allows the connecting lugs to rotate is provided at the bottom of the connecting hole.

[0023] The present application adopts a unique structural design of connecting lugs, slide slots, lifting springs and top plates, abandoning the original threaded connection method, greatly simplifying the installation and removal steps of the needle body. The operator only needs to align the connecting lug of the needle body with the slide slot and then rotate the needle body to connect the connecting lug to the slide slot. At the same time, the elastic force of the lifting spring and the top plate can be used to easily fix and position the needle body. Conversely, disassembly can also be completed quickly and easily, greatly improving work efficiency and reducing manual labor intensity.

[0024] The working principle of the present application is as follows: during installation, align the connecting lug with the slide slot of the connecting hole and insert the needle body. After insertion into place, rotate the needle body so that the connecting lug on the needle body deviates from the slide slot of the connecting hole, and then use the lifting spring and the ejector plate to lift the needle body. In this case, the lug is pressed tightly in the expansion ring groove and cannot slide out of the slide slot of the connecting hole, thereby completing the installation of the needle body. On the contrary, during disassembly, align the connecting lug of the needle body with the slide slot of the connecting hole, and then it can be ejected using the lifting spring, which makes disassembly and assembly very convenient.

[0025] Specifically, a positioning hole 9 is provided on the upper wall of the ring expansion groove, and a positioning column 10 capable of being inserted into the positioning hole is provided on the connecting lug.

[0026] This embodiment adds a positioning hole and a positioning column design on the basis of the above structure. By rotating the position of the needle body, the positioning column on the connecting lug can be accurately inserted into the positioning hole after the needle body is rotated into place, thereby accurately limiting the positioning and further ensuring the stability and accurate installation of the needle body during the rotation process. This improvement not only enhances the stability of the needle body in the working state and avoids the deviation or loosening of the needle body due to vibration and other reasons, but also simplifies the precise control of the rotation angle of the needle body during installation, thereby improving the assembly accuracy and work efficiency.

[0027] Specifically, the positioning hole and the positioning column are both conical structures.

[0028] The positioning hole and the positioning column adopt a conical structure design. This design allows a certain tolerance during the installation process. Even if the initial alignment is not accurate enough, the cone surface can guide the automatic centering during the insertion process, thereby improving the simplicity and success rate of the installation process. At the same time, the conical structure can also increase the friction between the connecting lug and the positioning hole, further strengthening the fixed state of the needle body, ensuring that it can remain stable under high-speed rotation working conditions, thereby extending the service life of the needle body and needle cup.

[0029] Specifically, a spring hole 11 is provided at the bottom of the connecting hole, and the lifting spring is fixedly connected to the bottom wall of the spring hole.

[0030] This design ensures that the lifting spring will not be displaced or fall off during operation, and always maintains effective elastic support. The existence of the spring hole optimizes the spatial layout, makes the needle installation structure compact, and ensures the reliable transmission of the spring force, so that the needle body can still maintain good floating and buffering performance when subjected to axial pressure, reducing the risk of damage to the needle body due to excessive force, while simplifying the installation and replacement steps of the spring, and improving the reliability and maintainability of the overall device.

[0031] Technical personnel should note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
