Abstract
Description
Technical Field
[0001] The utility model relates to the field of textile equipment, and more specifically to a swing arm brown belt supporting mechanism of a circular loom. Background Art
[0002] The circular loom is used to weave tubular cloth. The warp yarn is cross-opened by the brown belt, and the weft yarn shuttle moves in a circular motion in the cross-opening to pass through the warp yarn, and then weaves the tubular cloth. The swing arm on the circular loom is connected to the brown belt. The swing arm swings up and down, thereby driving the brown belt to move up and down, so that the weft yarn and the warp yarn are woven in place. However, during the actual operation of the machine, the swing of the swing arm will cause the brown belt to shake back and forth, thereby causing the warp yarn to shake, bringing instability to the weaving, which may cause defects in the final woven product. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model aims to provide a swing-arm brown belt support mechanism for a circular loom, which improves the stability of the brown belt's up and down movement and improves the weaving yield by adding a support member on the inner side of the brown belt.

[0005] As an improvement, the supporting member is a blocking wheel, which provides support and rolls synchronously when the brown belt moves up and down.
[0006] As an improvement, the diameter of the stop wheel gradually decreases from the middle to both sides, so that a bent contact surface is formed when the brown belt contacts the stop wheel.
[0007] As an improvement, the support members are evenly distributed in 24-54 groups on the middle annular frame.
[0008] As an improvement, the support members are evenly distributed on the middle annular frame in 28 groups, 32 groups, 36 groups, 40 groups, 48 groups, 52 groups, or 54 groups.

[0016] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0017] like Figure 1 , 2 , 3, and 4 are specific embodiments of the swing arm brown belt support mechanism of the circular loom of the utility model. The embodiment includes a main frame 1, which includes a lower annular frame 11 located at the bottom and an upper annular frame 12 located at the top, and a plurality of swing arms 2 are evenly distributed on the lower annular frame 11, and the middle part of the swing arms 2 swings, and the outer ends of the swing arms 2 are connected to the brown belt 3, and the brown belt 3 is wound around the rotating shaft 4 on the upper annular frame 12 and the lower annular frame 11. The main frame 1 also includes a middle annular frame 13 located in the middle, and a plurality of support members 5 are evenly distributed on the middle annular frame 13, and the support members 5 are arranged corresponding to the brown belt 3 to support the brown belt 3 on the inner side.
[0018] When the utility model is in use, the main shaft 10 is arranged at the central axis position of the main frame 1, and the cam 101 is arranged on the main shaft 10, the middle part of the swing arm 2 swings, and two upper and lower rollers 21 are arranged at the inner end, and the two rollers 21 are respectively located on the upper and lower surfaces of the cam 101. When the main shaft 10 drives the cam 101 to rotate, it synchronously drives the swing arm 2 to swing up and down, thereby making the brown belt 3 connected to the outer end of the swing arm 2 move up and down. Figure 4 As shown, the outer end of the swing arm 2 is connected to the inner side of the brown belt 3 ring, and drives the brown belt 3 to move up and down during operation. The support member 5 is further provided as shown in FIG. Figure 1 , 2The support shown is on the inner side of the brown belt 3, which provides stable support for the middle position of the brown belt 3 with a large upper and lower length span, thereby reducing the possibility of shaking of the brown belt 3, ensuring the neatness and order of the weft and warp yarns when they are cross-woven, and improving the weaving yield rate.
[0019] As an improved specific implementation manner, the support member 5 is a stopper wheel, which provides support and rolls synchronously when the brown belt 3 moves up and down.
[0020] like Figure 1 , 2 As shown in FIG. 3 , in a specific implementation, the support member 5 adopts a blocking wheel, which performs synchronous supporting rolling when the brown belt 3 moves, thereby reducing the influence of friction on the stability of the brown belt 3. On the one hand, the stability of the movement of the brown belt 3 is ensured, and on the other hand, the service life of the component is extended.
[0021] As an improved specific implementation method, the diameter of the stop wheel gradually decreases from the middle to both sides, so that a bent contact surface is formed when the brown belt 3 contacts the stop wheel.
[0022] like Figure 2 , 3 As shown, the middle part is more protruding than the two sides, so when the stopper wheel and the brown belt 3 come into contact, the middle part will come into contact first, and then the brown belt 3 will completely lean on the inner stopper wheel by slight deformation, forming a bent contact surface, thereby improving the friction state between the stopper wheel axial direction and the brown belt 3, improving the structural limiting capacity, preventing the brown belt 3 from deviating to the two sides, improving the stability of the up and down movement of the brown belt 3, and avoiding left and right shaking while reducing the shaking in the inner and outer directions.
[0023] As an improved specific implementation manner, the support members 5 are evenly distributed on the middle annular frame 13 in 24-54 groups, preferably 28 groups, 32 groups, 36 groups, 40 groups, 48 groups, 52 groups, and 54 groups.
[0024] like Figure 1 As shown, by setting a certain number of support members 5 to match the corresponding number of brown belts 3, the brown belt 3 support of the entire circumference is achieved; the number is selected according to the specification differences of the circular loom, and preferably 28 groups, 32 groups, 36 groups, 40 groups, 48 groups, 52 groups, and 54 groups are selected. The above even number groups are selected to facilitate the uniform arrangement of the circumference of the machine, reduce the difficulty of equipment manufacturing and processing, and ensure the weaving quality.
[0025] As an improved specific implementation method, an avoidance gap 6 is provided on the middle ring frame 13 corresponding to the installation position of the support member 5, and installation columns 7 are provided on the middle ring frame 13 on both sides of the avoidance gap 6, and the support member 5 is provided at the top of the installation column 7.
[0026] like Figure 2As shown, the setting of the avoidance gap 6 prevents the brown belt 3 from contacting the middle ring frame 13 when leaning against the support member 5, thereby avoiding interference between structures affecting stability. The mounting column 7 provides an upward support, so that the support member 5 is separated from the middle ring frame 13 by a certain distance, ensuring that the support member 5 independently supports the brown belt 3 without interference from the surrounding structure.
[0027] As an improved specific implementation manner, the middle annular frame 13 is arranged closer to the lower annular frame 11 than the upper annular frame 12 , so that the support member 5 is closer to the swing arm 2 .
[0028] like Figure 1 As shown, the swing of the swing arm 2 forms an inward and outward swing at the connection with the brown belt 3, and the shaking position of the brown belt 3 is this swinging position. The support member 5 is arranged closer to the swing arm 2, thereby providing support stability for the brown belt 3 above the shaking position, and cooperating with the rotating shaft 4 on the lower annular frame 11 below the shaking position, so that the shaking of the brown belt 3 when being driven by the swing arm 2 is effectively restricted, thereby improving the stability of the operation of the brown belt 3.
[0029] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
