Fabric textile products are widely used in clothing, home furnishings, industry and other fields. In the fabric weaving process, different fiber materials and process combinations can produce various fabrics with different properties and characteristics. The guide roller can guide the fabric to be smoothly transmitted in the textile machinery through its specific shape and structural design, and ensure that the fabric maintains the correct position and tension during the transmission process, which plays a positioning role in the transmission of the fabric, can reduce the deviation and wrinkles of the fabric during the transmission process, and improve product quality.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figures 1 to 4 A fabric weaving positioning device comprises two shaft heads 1, a cloth guide shaft body 2 is fixedly connected to the middle position between the two shaft heads 1, the shaft head 1 and the cloth guide roller body are both cylindrical, the interior of the cloth guide shaft body 2 is hollow, connecting rings 3 are symmetrically fixedly connected to the two sides of the inner wall of the cloth guide shaft body 2, an inner sleeve 4 is fixedly connected to the side wall between the two connecting rings 3, a motor 13 is fixedly connected to the side wall of the inner sleeve 4, a connecting column 5 is fixedly connected to the output end of the motor 13, a convex plate 6 is slidably connected to the interior of the cloth guide shaft body 2, the end of the convex plate 6 is wavy, and a driving mechanism is threadedly connected to one side of the convex plate 6, and the driving mechanism can drive the convex plate 6 to move linearly inside the cloth guide shaft body 2.

[0024] The working principle of this embodiment is as follows: a plurality of convex plates 6 can increase the contact area and friction between the cloth guide roller and the fabric, so that the fabric can be transmitted on the cloth guide roller more stably, and the deviation and sliding of the fabric during the transmission process are reduced. The end of the convex plate 6 is arranged in a wavy shape, and the end surface of the wavy convex plate 6 is composed of alternating convex surfaces and concave surfaces. This design has more points of contact with the fabric (or called "contact lines") on the end surface of the convex plate 6 of the same length than ordinary flat convex plates 6, because both the wavy convex and concave surfaces will come into contact with the fabric, thereby increasing the overall contact area, thereby increasing the friction, further preventing the fabric from deviating during transmission, and improving the positioning effect of the cloth guide roller.

[0025] Embodiment 2

[0026] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1 to 4 The driving mechanism includes a screw rod 701 , which is rotatably connected to the inner sleeve 4 , and a first bevel gear 702 is fixedly connected to the end of the screw rod 701 .

[0027] One side of the first bevel gear 702 is meshed with the second bevel gear 703 , and the second bevel gear 703 is fixedly connected to the outer side of the connecting column 5 .

[0028] By setting a driving mechanism, the motor 13 will drive the connecting column 5 to rotate after it is started, and the connecting column 5 will drive the second bevel gear 703 to rotate, the second bevel gear 703 will drive the first bevel gear 702 to rotate, and the first bevel gear 702 will drive the screw 701 to rotate. After the screw 701 rotates, it pushes the convex plate 6 to move linearly on the surface of the screw 701. The reciprocating movement of the convex plate 6 can be determined by the forward and reverse rotation of the motor 13. The reciprocating movement of the convex plate 6 makes the distance it extends out of the outside of the cloth guide shaft 2 adjustable, so that it can adapt to fabrics of different thicknesses and materials, further improving the applicability of the cloth guide roller.

[0029] The end of the connecting column 5 is rotatably connected to a counterweight block 8 , and the outer side of the counterweight block 8 is fixedly connected to the inner wall of the inner sleeve 4 .

[0030] By setting the counterweight block 8, the counterweight block 8 is symmetrically arranged with the motor 13, so that the weight on both sides of the cloth guide shaft body 2 is balanced, and the cloth guide shaft body 2 is prevented from shaking due to imbalance when rotating.

[0031] A positioning sleeve 9 is slidably connected to the outer side of the protruding plate 6 , and one side of the positioning sleeve 9 is fixedly connected to the inner side of the cloth guide shaft body 2 .

[0032] By providing the positioning sleeve 9, the positioning sleeve 9 can limit the convex plate 6, so that the convex plate 6 can move more stably during the reciprocating movement of the convex plate 6.

[0033] A sliding groove 10 is formed at the end of the protruding plate 6 , and a sliding column 11 is slidably connected inside the sliding groove 10 , and one side of the sliding column 11 is fixedly connected to the outer side of the inner sleeve 4 .

[0034] By providing the groove and the sliding column 11, the sliding column 11 enters the sliding groove 10 at the end of the convex plate 6 to further limit the convex plate 6, thereby preventing the convex plate 6 from shaking during the reciprocating movement and causing movement jamming.

[0035] The outer side of the sliding column 11 is sleeved with a spring 12 , and one end of the spring 12 is fixedly connected to the outer side of the inner sleeve 4 .

[0036] By providing the spring 12 , the spring 12 can exert elastic force on the convex plate 6 , thereby making the connection between the convex plate 6 and the screw rod 701 tighter.

[0037] There are several convex plates 6 , and the several convex plates 6 are distributed in a ring shape with equal distances. The several convex plates 6 have different lengths, and the several convex plates 6 are arranged in a wave shape.

[0038] The distances at which the several convex plates 6 extend out of the guide shaft body are different. The different extension distances form a highly undulating wave shape between the several convex plates 6. During the rotation of the cloth guide roller, different convex plates 6 will contact the fabric transmitted on the surface as they rotate, thereby providing a more comprehensive guiding and supporting effect.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
