Description

Technical Field

[0001] This utility model belongs to the field of material guiding protection technology for multi-arm looms, and relates to a multi-arm loom with a connecting rod protection structure. Background Technology

[0002] The multi-arm loom is a specialized semi-automatic mechanical device widely used in the textile industry. This machine is primarily used to produce various fabrics. Its operation relies on computer control and multiple linkage supports, enabling the creation of complex fabric patterns. The yarn feeding mechanism is a crucial component of the multi-arm loom, responsible for guiding the yarn from the yarn supply device to the weaving area, ensuring accurate and stable yarn transmission during the weaving process. The design and operation of this mechanism directly affect fabric quality and production efficiency. The yarn feeding mechanism within the multi-arm loom is a key component of textile machinery, responsible for precisely guiding the yarn to ensure smooth weaving. If this mechanism lacks a protective structure for the connecting rods and guide wires, it will cause a series of problems, severely impacting weaving quality and equipment stability.

[0003] The lack of a protective mechanism can lead to unstable yarn tension. During weaving, the yarn needs to maintain a constant tension to ensure the uniformity and stability of the fabric. However, without a protective mechanism, the tension link may be affected by external interference or wear, causing tension fluctuations and thus affecting the quality of the fabric. Therefore, there is an urgent need for a multi-arm loom with a link protection structure to solve these problems. Utility Model Content

[0029] The bottom shell 180 has an inlet 190 on the right side for introducing the yarn material and an outlet 200 on the left side for discharging the yarn material. Both the outlet 200 and the inlet 190 have a set of guide rollers 140 for protecting and guiding the yarn material. The yarn material can be protected and guided by the guide rollers 140.

[0030] The outer shell 100 and the bottom shell 180 are an integral structure. Both the outer shell 100 and the bottom shell 180 are hollow structures, and the interior of the outer shell 100 and the bottom shell 180 constitutes the guide cavity of the guide mechanism of the multi-arm loom.

[0031] The adjusting component 120 includes an electric cylinder 12a, a guide post 12b, a movable seat 12c, an inner shaft 12d, and a guide roller 12e. The lower end of the electric cylinder 12a is provided with a set of guide posts 12b for controlling the up and down movement of the movable seat 12c. The lower end of the guide posts 12b is provided with a set of movable seats 12c for driving the guide roller 12e to move up and down. Inside the movable seat 12c is a set of inner shafts 12d for driving the guide roller 12e to rotate. Outside the inner shafts 12d is a set of guide rollers 12e for guiding the yarn material.

[0032] The guide roller 140 includes a roller body 14a and a protective roller 14f. A set of limiting bearings for limiting the roller body 14a is provided on the outer sides of both the front and rear sides. A set of brackets 14e for supporting and connecting the limiting bearings is provided on the left side of the two sets of limiting bearings. A set of inner connecting rods for rotation is provided inside the roller body 14a.

[0033] Both the front and rear sides of the inner connecting rod are provided with a set of front movable connecting rods 14b that drive the support connecting rods 14c to move. The lower end of the front movable connecting rods 14b is provided with a set of support connecting rods 14c for driving the position support movement of the protective roller 14f. Inside the two sets of support connecting rods 14c, there is a set of protective rollers 14f for adaptive tension and relaxation protection of the yarn material. Both the front and rear ends of the protective roller 14f are provided with a set of rear movable connecting rods 14d for supporting the support connecting rods 14c. The protective rollers 14f can be used to adaptively relax and protect the yarn material tension.

[0034] Please see Figures 1-4As the first embodiment of this utility model: To solve the problem that the lack of a protective mechanism leads to unstable yarn tension, during the weaving process, the yarn needs to maintain a constant tension to ensure the uniformity and stability of the fabric. However, without a protective mechanism, the tension link may be affected by external interference or wear, resulting in tension fluctuations and thus affecting the fabric quality. First, the operator guides the yarn to be fed through the lower surface of the protective roller 14f, the upper surface of the roller body 14a, and the upper surface of the guide roller 12e, and performs the guiding operation for the yarn used in the multi-arm loom. During the guiding process, the yarn guiding tension is squeezed and supported by the lower end of the protective roller 14f. Due to the inner connecting rod and the two sets of front movable connecting rods 14b Several sets of rotary damping devices are provided between the two sets of front movable connecting rods 14b and the two sets of support connecting rods 14c, between the two sets of support connecting rods 14c and the two sets of rear movable connecting rods 14d, between the front and rear sides of the protective roller 14f, and between the two sets of rear movable connecting rods 14d and the bracket 14e. These devices are used to control the adaptive adjustment of the yarn material on the outside of the protective roller 14f. When the yarn tension is too high, these rotary damping devices support the protective roller 14f and provide downward resistance, thus maintaining the yarn tension and preventing it from increasing further. When the yarn tension is too low, these rotary damping devices can drive the protective roller 14f to further compress the yarn downwards, thereby maintaining the yarn tension and preventing the yarn from getting tangled or breaking during the weaving process.

[0035] Please see Figures 1-4 As a second embodiment of this utility model: Based on the description in the above embodiments, further, when the protective roller 14f adaptively adjusts according to the yarn tension, its front movable link 14b, support link 14c and rear movable link 14d can provide deformation position support for the front and rear sides of the protective roller 14f, thereby ensuring the stability of the protective roller 14f. At the same time, the operator can actively adjust the electric cylinder 12a to move the movable seat 12c up and down, thereby causing the guide roller 12e to actively move up and down, actively adjust the yarn tension, and ensure the weaving effect of the multi-arm loom.

[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.
