Description

Technical Field

[0001] This utility model belongs to the field of yarn frame technology, and in particular relates to an adjustable yarn guide frame for woven bags. Background Technology

[0002] The yarn guide frame for woven bags is a key piece of equipment used for yarn guidance and tension control in woven bag production. Its core function is to ensure that the yarn path is stable and the tension is uniform during the weaving process, taking into account both yarn guidance accuracy and production efficiency. It is commonly used in industrial scenarios that require high-density weaving.

[0003] Currently, yarn often bounces when passing through yarn rollers due to factors such as tension, affecting the quality of normal production operations.

[0004] To address the aforementioned issues, this application proposes an adjustable yarn guide frame for woven bags. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable yarn guide frame for woven bags, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an adjustable yarn guide frame for woven bags, including a fixed frame and a support frame above it;

[0008] A carriage is provided on the outside of the support frame. In front of the carriage, there are relatively distributed supports. A main roller is rotatably installed between adjacent supports. At the upper position of the left and right ends of the adjacent supports, there are auxiliary rollers that can slide up and down. The axis of the auxiliary roller is located at one-quarter of the distance from the upper edge of the main roller to the axis.

[0009] The auxiliary roller has symmetrically distributed sliding sleeves on both outer sides, and positioning discs are provided on the opposite surfaces of adjacent sliding sleeves.

[0010] Preferably, the lower ends of the opposite surfaces of adjacent supports are provided with bosses, which are connected and fixed to each other by connecting rods.

[0011] Preferably, the inner side of the bracket is provided with an upward through-slide, and the two ends of the shaft of the auxiliary roller are fixed with sliders.

[0012] Preferably, the slider has a T-shaped block on its side that is slidably connected to the slide rail.

[0013] Preferably, a micro-pressure adjustment part is provided above both ends of the boss, which is connected to the lower end of the slider extension plate.

[0014] Preferably, the micro-pressure adjustment unit is used to drive the auxiliary roller to adapt to changes in yarn tension.

[0015] Preferably, the inside of the sliding sleeve is provided with a blocking pad that fits tightly against the auxiliary roller.

[0016] This utility model has the following beneficial effects:

[0017] This invention utilizes the staggered linkage between the main roller and the auxiliary roller to pre-press the yarn slightly as it passes through, ensuring a stable traction trajectory as it passes the main roller. This achieves automatic tension adjustment and effectively prevents yarn skipping caused by tension changes.

[0018] This invention uses symmetrically distributed sliding sleeves at both ends of the auxiliary roller to limit the movement path of the yarn within a fixed range when guiding the yarn, restricting its lateral slippage, further preventing yarn skipping, and also preventing scratching of the main roller during slippage.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] 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.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Please see Figure 1-4 As shown, this utility model is an adjustable yarn guide frame for woven bags, including a fixed frame 1 and a support frame 11 above it;

[0032] The slide 21 is located on the outside of the support frame 11. In front of the slide 21, there are relatively distributed supports 22. One of the supports 22 is fixedly connected to the slide 21. A main roller 23 is rotatably installed between adjacent supports 22. The fixed shaft inside the main roller 23 is fixedly connected to the adjacent support 22. At the upper position of the left and right ends of the adjacent supports 22, there are auxiliary rollers 24 that can slide up and down. The axis of the auxiliary roller 24 is located at one-quarter of the distance from the upper edge of the main roller 23 to the axis. It slightly presses down the passing yarn so that it sticks to each other when passing through the main roller 23, thereby achieving the effect of preventing jumping.

[0033] Symmetrically distributed sliding sleeves 26 are fitted on the outer sides of both ends of the auxiliary roller 24. Positioning discs 261 are provided on the opposite faces of adjacent sliding sleeves 26. The yarn is fixed between adjacent positioning discs 261 for traction, which can effectively prevent the yarn from slipping laterally and thus avoid scratching the main roller 23.

[0034] Furthermore, each of the lower ends of the opposite face of the adjacent brackets 22 is provided with a boss 221, which is connected and fixed to each other by a connecting rod 222 to support the brackets 22 suspended on the outside and prevent them from sagging and affecting the traction of the yarn.

[0035] Furthermore, the inner side of the bracket 22 is provided with an upward through slide 223, and the two ends of the rotating shaft of the auxiliary roller 24 are fixed with sliders 25. The sides of the sliders 25 are provided with T-shaped blocks that are slidably connected to the slide 223 to fix the path of the auxiliary roller 24 sliding up and down.

[0036] Furthermore, micro-pressure adjustment parts 27 are provided above both ends of the boss 221 and connected to the lower end of the slide block 25. They adopt an electric telescopic rod mechanism with a sensor to adjust the downward pressure distance of the auxiliary roller 24 according to the change of yarn tension, thereby achieving the effect of making the auxiliary roller 24 adapt to the change of yarn tension.

[0037] Furthermore, the inside of the sliding sleeve 26 is provided with a blocking pad 262 that is close to the auxiliary roller 24 and is clamped to the outside of the auxiliary roller 24 by friction.

[0038] It is understood that this invention can confine the yarn within a fixed area when pulling it, and adjust the pressing depth of the yarn in real time according to the change of its tension, so as to keep it stable during pulling and prevent jumping and scratching of the roller body.

[0039] A specific application of the operation process of this embodiment is as follows: During use, the yarn passing through the main roller 23 is pre-pressed down by the auxiliary roller 24. Under the action of the micro-pressure adjustment part 27, the yarn is slightly pressed down, so that even if the yarn tension changes, it can still be pulled against the main roller 23 to prevent the yarn from jumping during the pulling process. At the same time, the traction path of the yarn is fixed by using the 16 sleeved on both ends of the auxiliary roller 24, so that it is pulled between adjacent positioning disks 261. This further prevents yarn skipping, and the limitation of lateral displacement can also prevent the yarn from scratching the main roller 23 and reduce its wear.
