Description

Technical Field

[0001] This utility model relates to the technical field of yarn finishing devices, specifically to an antibacterial finishing device for blended yarn. Background Technology

[0002] To meet consumers' demands for the hygiene and safety of textiles, blended yarns often undergo an antibacterial finishing process. This process imparts antibacterial properties by applying antibacterial agents, and the blended yarn antibacterial finishing device is the key equipment for achieving this process. During the antibacterial finishing of blended yarns, to ensure uniform finishing results and avoid finishing defects caused by yarn breakage or loosening, a stable tension must be applied to the yarn using tension rollers.

[0003] In existing blended yarn antibacterial finishing devices, the position adjustment of the tension roller mostly relies on a cantilever structure. Typically, one or both ends of the tension roller are connected to the cantilever, and the position of the tension roller is changed by driving the cantilever to swing or move, thereby adjusting the yarn tension. When the cantilever moves the tension roller, the part of the cantilever away from the connection end is prone to significant deflection deformation. This is especially noticeable when the tension roller is subjected to continuous tension from the yarn or when the device vibrates during operation. This swaying of the cantilever becomes more pronounced, leading to a decrease in the positional accuracy of the tension roller and an inability to stably maintain the preset yarn tension, thus affecting the uniformity of the antibacterial finishing. Therefore, this invention provides a blended yarn antibacterial finishing device. Utility Model Content

[0004] The purpose of this invention is to provide an antibacterial finishing device for blended yarn.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0008] A tension roller is provided between the two inner guide rollers in the same group. The two ends of the tension roller are connected to the bottom end of the cantilever. The top end of the cantilever extends to the top of the box and is connected to a crossbeam. A sliding groove is provided on the inner wall of the box. A sliding protrusion is provided on the side of the cantilever that slides in the sliding groove. A cross plate is provided on the cantilever corresponding to the inner guide roller. A sliding through groove adapted to the inner guide roller is opened in the cross plate.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0021] like Figure 1 and Figure 2 As shown, a blended yarn antibacterial finishing device includes: a box body 1, the box body 1 having a space inside to hold antibacterial finishing liquid, an opening at the top, and an inlet and outlet guide roller 2 provided above the opening, the inlet and outlet guide roller 2 being two rollers located at both ends of the opening, used to guide the yarn into the box body 1 and out of the box body 1.

[0022] The housing 1 contains two sets of inner guide rollers 3 symmetrically distributed along its centerline. Each set of inner guide rollers 3 consists of two rollers, arranged vertically to guide the yarn vertically. The two sets of inner guide rollers 3 ensure that the yarn has at least two vertical conveying sections to cooperate with the left and right tension rollers 4 respectively.

[0023] A tension roller 4 is positioned between the two inner guide rollers 3 in the same group. Both ends of the tension roller 4 are connected to the bottom of a cantilever 5, and the top of the cantilever 5 extends above the housing 1 and is connected to a crossbeam 6. The tension roller 4 acts on the vertical conveying section of the yarn, squeezing the yarn inward to increase its tension; reversing its movement reduces the yarn tension. Preferably, the tension roller 4 is equidistant from the upper and lower inner guide rollers 3.

[0024] like Figure 3 and Figure 4 As shown, a groove 7 is provided on the inner wall of the box 1, and a sliding protrusion 8 is provided on the side of the cantilever 5, which slides within the groove 7 to improve the stability of the cantilever 5. Preferably, both the groove 7 and the sliding protrusion 8 are supported by ultra-high molecular weight polyethylene (UHMWPE). UHMWPE has excellent corrosion resistance, high resistance to most chemicals, especially various acid and alkali solutions; excellent sliding properties, with a very low coefficient of friction and outstanding wear resistance, more than 10 times that of carbon steel; extremely high impact resistance, light weight, and extremely low water absorption. UHMWPE is a material that combines excellent corrosion resistance, self-lubrication, and good sliding performance without the need for additional lubrication. It can be used in solutions without the need for lubricating oil, thus avoiding contamination.

[0025] The slide 7 has limiting structures at both ends to limit the movement range of the slide convex 8 and the cantilever 5.

[0026] A horizontal plate 11 is provided at the cantilever 5 corresponding to the inner guide roller 3. The horizontal plate 11 has a sliding groove adapted to the inner guide roller 3. Since the tension roller 4 is located between the upper and lower inner guide rollers 3, the cantilever 5 at both ends will coincide with the shaft of the upper inner guide roller 3. To avoid mutual interference, a sliding groove is provided on the cantilever 5, and the shaft of the inner guide roller 3 is located in the sliding groove to avoid affecting the sliding of the cantilever 5.

[0027] The end of the crossbeam 6 is threadedly engaged with the lead screw 9, which is rotatably mounted on the housing 1. One end of the lead screw 9 is connected to the servo motor 10 for transmission. The lead screw 9 has two sets of threads in different directions on its surface, and the two sets of threads are respectively engaged with the two crossbeams 6 on the same side. The servo motor 10 drives the lead screw 9 to rotate, which in turn drives the two crossbeams 6 and the cantilever 5 to move closer or further apart, thereby driving the movement of the two tension rollers 4 to adjust the yarn tension.

[0028] The top of the housing 1 is provided with mounting bases 12 on both sides, the lead screw 9 is mounted on the mounting base 12, and the servo motor 10 is fixed on the mounting base 12. The bottom of the crossbeam 6 is provided with a sliding block 13 connected thereto. The sliding block 13 slides in the sliding groove 14 opened on the mounting base 12 to improve the stability of the crossbeam 6 sliding.

[0029] The mounting base 12 is covered by a cover 15, which covers the components on the mounting base 12 and provides isolation and protection.

[0030] A cover plate 16 is provided at the top opening of the box 1 to seal the box 1 and reduce the evaporation of the finishing liquid and the entry of impurities into the box 1. The cover plate 16 has a slot for the cantilever 5 to slide, and also has a slot for the yarn to enter.

[0031] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
