Description

Technical Field

[0001] This utility model relates to the technical field of chemical fiber twisting equipment, and more specifically, to a twisting protection device. Background Technology

[0002] In the field of chemical fiber processing, twisting equipment is a key device for twisting yarns and improving their strength and elasticity. Currently, widely used twisting devices typically employ a "rabbit head" structure as their core component. This structure is fixed to the frame via a guide shaft and reciprocates under the action of a drive mechanism to twist the yarns. While this structure meets the basic requirements of the twisting process to a certain extent, it still has many shortcomings in practical applications.

[0003] First, the traditional "rabbit head" structure, when operating at high speeds, is prone to causing lubricating oil in the lubrication system to be thrown out due to the reciprocating vibration and centrifugal force of the moving parts. This results in contamination of the yarn and finished yarn rolls, affecting product quality and even causing problems such as yarn breakage and adhesion during subsequent processing. Second, the existing equipment has relatively weak guiding and protection measures for the yarn, making it prone to yarn wear, misalignment, or breakage during twisting, reducing the stability and reliability of the equipment operation. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a twist protection device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A twisting protection device includes a frame, a twisting pressure roller inside the frame, a rabbit head assembly below the twisting pressure roller, a guide sleeve, a roller swivel connected to one side of the guide sleeve, a fixing block connected to one side of the guide sleeve, a wire pulling blade connected above the fixing block, an opening at the top of the wire pulling blade, a rubber swivel protection head connected to one side of the opening, and wire protection rubber connected to the other two sides of the opening.

[0007] Furthermore, in order to drive the rabbit head assembly to reciprocate, a drive roller is provided on one side of the roller blade, and the surface of the drive roller is provided with a bidirectional threaded groove. Rotating wheels are connected to both ends of the roller blade, and the rotating wheels are matched with the bidirectional threaded groove.

[0008] Furthermore, in order to connect the drive roller to the frame, both ends of the drive roller are connected to the frame via bearings.

[0009] Furthermore, to prevent the guide sleeve from shifting during movement, a guide shaft is connected through the inside of the guide sleeve, with both ends of the guide shaft connected to the frame.

[0010] Furthermore, in order to form a dynamic sealing interface, one side of the wire-drawing blade is U-shaped, and a baffle is provided on one side of the guide shaft, with one end of the baffle located inside the wire-drawing blade.

[0011] Furthermore, the baffle is connected to the frame via a connecting rod, and the connecting rod is connected to the frame via a bearing.

[0012] Furthermore, a partition is provided on the outside of the drive roller, and the partition is connected to the frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] By employing a U-shaped rabbit head assembly with a baffle on one side of the guide shaft, one end of the baffle is embedded inside the U-shaped structure of the wire-drawing blade. During twisting and the lifting action of the wire-drawing blade, a dynamically changing but always sealed closed space can be formed. This structural design overcomes the limitations of traditional open or semi-closed rabbit head assemblies in terms of lubrication system protection. Through the cooperation between the baffle and the U-shaped wire-drawing blade, adaptive sealing is achieved during the movement of the rabbit head assembly, ensuring that the grease is always confined within the set closed area, preventing splashing or overflow due to high-speed operation or reciprocating oscillation. This dynamic sealing structure not only effectively prevents grease from contaminating the yarn and finished yarn rolls, but also significantly improves the cleanliness and stability of equipment operation.

Detailed Implementation

[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 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] According to an embodiment of the present invention, a twisting protection device is provided.

[0025] Example 1

[0026] like Figures 1-5 As shown, the twisting protection device according to an embodiment of the present utility model includes a frame 1. The frame 1 serves as the basic support structure of the entire device. The frame 1 is made of high-strength metal material, has good structural stability and load-bearing capacity, and can install and fix other functional components.

[0027] The frame 1 is equipped with a twisting pressure roller 2, which is one of the core components for realizing the twisting function of the yarn. It is driven to rotate by the power system and cooperates with the rabbit head assembly 3 below to apply twisting force to the yarn, thereby improving the strength and uniformity of the yarn. The rabbit head assembly 3 is located below the twisting pressure roller 2, which can perform reciprocating swing and local lifting actions to realize dynamic guidance and twisting of the yarn.

[0028] like Figure 5 As shown, the rabbit head assembly 3 includes a guide sleeve 301. A roller paddle 302 is rotatably connected to one side of the guide sleeve 301, allowing it to swing left and right with the rotation of the drive roller 10. A fixing block 303 is connected to one side of the guide sleeve 301, serving as the mounting base for the wire-pulling plate 304 and providing structural connection and support. The wire-pulling plate 304 is connected above the fixing block 303. An opening 305 is provided at the top of the wire-pulling plate 304. A rubber paddle protection head 306 is connected to one side of the opening 305, and wire protection rubber 307 is connected to the other two sides of the opening 305. The wire protection rubber 307 and the rubber paddle protection head 306 together form a wire guiding channel, providing all-round flexible protection for the wire and preventing wire breakage or surface damage caused by direct contact with metal parts.

[0029] like Figure 4 and Figure 5 As shown, a drive roller 10 is provided on one side of the roller tweezer 302. The surface of the drive roller 10 is provided with a bidirectional threaded groove 4. Rotating wheels 5 are connected to both ends of the roller tweezer 302. The rotating wheels 5 are matched with the bidirectional threaded groove 4. The drive roller 10 is driven to rotate by a drive motor. When the drive roller 10 rotates, it drives the roller tweezer 302 to swing back and forth through the meshing transmission between the threaded groove and the rotating wheel 5, thereby realizing the overall movement of the rabbit head assembly 3. The two ends of the drive roller 10 are connected to the frame 1 through bearings. A guide shaft 6 is connected through the guide sleeve 301 to guide and limit the movement trajectory of the rabbit head assembly 3, preventing it from deviating or shaking during the movement, and ensuring the stability and consistency of the twisting action.

[0030] like Figure 2 and Figure 5 As shown, the guide shaft 6 is connected to the frame 1 at both ends. The wire-pulling blade 304 has a U-shape on one side, and a baffle 7 is provided on one side of the guide shaft 6. One end of the baffle 7 is located inside the wire-pulling blade 304. This structural design can effectively prevent grease from splashing or overflowing during high-speed operation. The baffle 7 is connected to the frame 1 through a connecting rod 8, which is connected to the frame 1 through a bearing. The left and right sides of the connecting rod 8 are driven to rotate by cylinders, which can drive the baffle 7 to tilt, thereby dynamically adjusting the sealing area under different working conditions, improving the sealing effect and adaptability.

[0031] like Figure 3 As shown, a partition 9 is provided on the outer side of the drive roller 10. The partition 9 is connected to the frame 1 and serves to isolate and protect the roller.

[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0033] In summary, with the help of the above-mentioned technical solution of this utility model, when the power system drives the twisting roller 2 to rotate, it cooperates with the rabbit head assembly 3 below to apply twisting force to the yarn passing through the yarn guide channel. At the same time, the drive roller 10 rotates under the drive motor, and the bidirectional threaded groove 4 on its surface meshes with the rotating wheels 5 at both ends of the roller chuck 302, driving the roller chuck 302 and its connected rabbit head assembly 3 to swing back and forth, thereby realizing the dynamic guidance and continuous twisting action of the yarn.

[0034] During the movement of the rabbit head assembly 3, the guide sleeve 301 slides along the guide shaft 6. The guide shaft 6 limits and guides the movement trajectory of the entire assembly, preventing it from deviating or vibrating, thereby ensuring the stability and consistency of the twisting action. In addition, the wire drawing plate 304 adopts a U-shaped structure design, and a baffle 7 is provided on one side of the guide shaft 6. One end of the baffle 7 is embedded inside the wire drawing plate 304, forming a dynamic sealed space.

[0035] During high-speed operation of the device, the grease is strictly confined within the sealed area, fundamentally solving the problem of grease splashing and contaminating the threads in traditional structures. The baffle 7 is hinged to the frame 1 via a connecting rod 8, with a bearing connecting the connecting rod 8 and the frame 1, ensuring the baffle 7 moves flexibly and stably. The left and right sides of the connecting rod 8 are driven to rotate by cylinders, enabling the baffle 7 to tilt upwards, thereby dynamically adjusting the sealing area according to different working conditions, improving sealing effect and adaptability.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
