AI Technical Summary
In a warp knitting machine, as the braid width and the diameter of the rolling cloth increase, the guide cloth roller is easily trapped and bent by the grey braid, resulting in insufficient rigidity of the guide roller and unstable rolling cloth.
An anti-tightening mechanism is designed, installed on the first support beam, including a support plate, a roller and a pin, and the roller is tangent to the guide cloth roller to prevent the guide cloth roller from being pulled in.
It effectively improves the rigidity of the guide cloth roller and the stability of the roll cloth to ensure that the grey cloth can be rolled normally.

Abstract
Description
Technical Field
[0001] The utility model relates to a warp knitting machine, in particular to a cloth rolling device of the warp knitting machine. Background Art
[0002] The cloth rolling device of the warp knitting machine is used to roll up the woven fabric for easy storage and transportation. Figure 1 As shown, it generally includes a first cloth guide roller 1', a second cloth guide roller 2', a first cloth roll roller 3' and a second cloth roll roller 4' arranged in sequence along the cloth feeding direction, the first cloth roll roller 3' is an active roller driven by a servo motor, the second cloth roll roller 4' is a passive roller, and the first cloth roll roller 3' and the second cloth roll roller 4' are chain-driven. The first cloth guide roller 1' and the second cloth guide roller 2' are passive rollers driven by the friction force of the blank cloth 100'. The first cloth guide roller 1', the second cloth guide roller 2', the first cloth roll roller 3' and the second cloth roll roller 4' are all installed on two wall panels 10', and a first support beam 5' and a second support beam 6' are installed between the two wall panels 10'. The length direction of the first support beam 5' and the second support beam 6' is parallel to the axial direction of the first cloth guide roller 1', and the first support beam 5' and the second support beam 6' are used to support the two wall panels and ensure that the two wall panels are parallel.
[0003] In recent years, in order to improve weaving efficiency, the width of warp knitting machines has been continuously increased. A warp knitting machine has increased from opening 1 cloth to opening 4 cloths, and the cloth rolling diameter has increased from 0.5 meters to more than 1 meter. In the process of rolling the grey cloth, the grey cloth will pull the first cloth guide roller toward the support beam adjacent to the first cloth guide roller. Since the cloth guide roller is a slender piece with insufficient rigidity, the first cloth guide roller will be pulled obliquely and bent. The closer to the middle position of the cloth guide roller, the easier it is to be pulled obliquely. In order to ensure the rigidity of the cloth guide roller and the stability of the cloth rolling, it is necessary to improve the existing cloth rolling device. Utility Model Content

[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0018] like Figures 2 to 4As shown, a warp knitting machine cloth guide roller anti-skew mechanism comprises a first cloth guide roller 1, a first cloth winding roller 2 and a second cloth winding roller 3 which are installed between two wall panels 10 and arranged in sequence along the cloth feeding direction, a first support beam 4 and a second support beam 5 are also installed between the two wall panels 10, the length directions of the first support beam 4 and the second support beam 5 are parallel to the axial direction of the first cloth guide roller 1, and the first support beam 4 is located between the first cloth guide roller 1 and the first cloth winding roller 2 and close to the first cloth guide roller 1.
[0019] like Figures 3 to 5 As shown, two anti-skewing mechanisms 6 are installed on the first support beam 4 at intervals along the length direction of the first support beam 4, each of the anti-skewing mechanisms 6 includes a support plate 61, the support plate 61 includes a vertical portion 611 and a hook portion 612 at the upper end of the vertical portion 611, the hook portion 612 is hung on the upper end portion of the first support beam 4, the vertical portion 611 is in contact with the side surface of the first support beam 4 and is connected by a fixing bolt 62, two pins 63 are installed on the lower end side of the vertical portion 611, the two pins 63 are arranged parallel to each other up and down, the axial direction of the pins 63 is parallel to the axial direction of the first cloth guide roller 1, and a roller 64 is rotatably installed at both ends of each pin 63, and the roller 64 is tangent to the first cloth guide roller 1.
[0020] The support plate 61 described in this embodiment is directly hung on the first support beam, and its appearance changes according to the size of the first support beam 4. As long as the vertical portion 611 and the hook portion 612 can fit with the first support beam 4, the support plate 61 can be moved to any position in the horizontal position of the first support beam. When the support plate 61 moves to the required width of the cloth, the fixing bolts 62 are tightened and the position of the support plate is fixed.
[0021] When the grey cloth 100 pulls the first cloth guide roller 1 toward the first support beam 4, since the outer surface of the first cloth guide roller 1 is tangent to the roller 64, the roller 64 passively rotates along with the first cloth guide roller 1, limiting the first cloth guide roller 1 from further deformation toward the first support beam 4 and ensuring that the surface of the first cloth guide roller 1 is not damaged, thereby ensuring the normal rolling of the grey cloth 100, and forming a grey cloth roll 200 between the first cloth rolling roller and the second cloth rolling roller.
[0022] The number of the anti-skewing mechanism described in the utility model is not limited, and one or more can be set according to the working conditions. The number and size of the rollers are not limited, as long as they can be tangent to the first cloth guide roller to form support for the part that is prone to skewing; the hook part is set as needed, and the additional hook part can increase the stability of the support plate installation; the rotatable structure of the roller is not limited to that shown in the embodiment, and the pin shaft can also be rotatably installed on the vertical part, and then the roller and the pin shaft are fixed. This is a conventional technical means in the mechanical field and will not be elaborated here.
[0023] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
