Description

Technical Field

[0001] The utility model belongs to the technical field of fabric processing, and particularly relates to a fabric weft straightening machine. Background Art

[0002] A fabric weft straightening machine, also known as a weft straightening machine or a fabric weft straightening device, is a device in the textile industry. Its main function is to correct and improve the problem that the weft yarns of textiles (such as fabrics, knitted fabrics, towels, etc.) deviate from the vertical direction and are not straight or twisted during the weaving process, that is, weft skew, weft slant, and weft arc deformation.

[0003] For the existing fabric weft straightening machine, after the fabric is limited and clamped by the limit rollers on the upper and lower sides in the limit conveying module, the fabric is conveyed by the rotation of the limit rollers. During the conveying process, the electric push rod drives the weft straightening roller or the weft straightening frame to press down through the cylinder, so that the weft straightening roller or the weft straightening frame squeezes the fabric during the conveying process to achieve the weft straightening of the fabric. However, in the actual use process, due to the relatively single weft straightening direction, the weft straightening effect on the fabric is not very ideal. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies of the prior art, the utility model provides a fabric weft straightening machine. Through the cooperation of the weft straightening frames on the left and right sides, the weft straightening frames can straighten the fabric from the upper and lower directions during their own rotation, and thus can straighten the fabric from multiple directions, which can effectively improve the weft straightening effect on the fabric.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a fabric weft straightening machine, including a frame. A plurality of uniformly distributed supporting feet are arranged on the lower surface of the frame. A plurality of uniformly distributed supports one are arranged on the inner walls of the front and rear sides of the frame. Guide rails are respectively arranged between two vertically adjacent supports one. A movable seat is slidably arranged between two adjacent front and rear guide rails. A limit roller is rotatably arranged inside each movable seat. A driving motor one is arranged on the front side of each upper movable seat. The output shafts of the driving motors one are respectively fixed to the adjacent limit rollers through couplings. Guide chute one is opened on the left side of the inner walls of the front and rear sides of the frame, and guide chute two is opened on the right side of the inner walls of the front and rear sides of the frame. A sliding plate one is slidably arranged between two guide chute ones, and a sliding plate two is slidably arranged between two guide chute twos. Two weft straightening frames that are symmetrically distributed front and rear are rotatably arranged on the lower surface of the sliding plate one and the upper surface of the sliding plate two. An electric drive module for driving the limit roller to move is further arranged on the frame, and an electric control module for driving the weft straightening frame to move is further arranged on the frame; two driving motors two that are symmetrically distributed front and rear are arranged on the lower surface of the sliding plate one and the upper surface of the sliding plate two. The output shafts of the driving motors two are respectively fixed to the adjacent weft straightening frames through couplings; rubber sleeves are fixedly sleeved on the outer sides of the limit rollers.

[0006] As a further improvement of the utility model, the electric drive module includes a double-shaft motor I uniformly arranged on the inner walls of the front and rear sides of the frame. A regulating lead screw I is rotatably arranged between two adjacent supports I in the vertical direction. The outer sides of the regulating lead screws I are respectively threadedly connected to the adjacent movable seats, and the output shafts of the double-shaft motor I are respectively fixed to the adjacent regulating lead screws I through couplings.

[0007] As a further improvement of the utility model, the electric control module includes drive boxes arranged on the front and rear sides of the frame. Four supports II are vertically and uniformly distributed inside each drive box. Slide rails are respectively arranged between two adjacent supports II in the vertical direction. Sliding plates are slidably arranged on the outer sides of the slide rails. The lower surface of the first sliding plate and the upper surface of the second sliding plate are respectively connected and fixed to the adjacent connecting plates. An electric control unit for driving the first sliding plate to move is further arranged on the drive box; the electric control unit includes a regulating lead screw II rotatably arranged between two adjacent supports II in the vertical direction. The regulating lead screw II is respectively threadedly connected to the adjacent connecting plates. A double-shaft motor II is arranged in the middle of the interior of each drive box, and the output shafts of the double-shaft motor II are respectively fixed to the adjacent regulating lead screws II through couplings.

[0008] As a further improvement of the utility model, a control panel is arranged on the front side of the frame. The double-shaft motor I, the drive motor I, the drive motor II and the double-shaft motor II are all electrically connected to the control panel.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] First, the double-shaft motor I is controlled by the control panel to operate synchronously, so that the regulating lead screw I drives the adjacent movable seat to slide between the two guide rails, and the upper and lower movable seats drive the limiting rollers to move closer to each other to contact and limit the fabric.

[0011] Second, the two double-shaft motors II are controlled by the control panel to operate synchronously, driving the first sliding plate to slide downward between the two first guide chutes and the second sliding plate to slide upward between the two second guide chutes, so that the two weft straightening frames on the left squeeze the fabric downward and the two weft straightening frames on the right squeeze the fabric upward, and the fabric can be weft straightened from the upper and lower directions.

[0012] Third, the drive motors I and II are driven to operate through the control panel. The fabric in the conveying process is weft straightened by the rotating weft straightening frames. The cooperation of the weft straightening frames on the left and right can weft straighten the fabric from the upper and lower directions during the rotation of the weft straightening frames themselves, and thus the fabric can be weft straightened from multiple directions, effectively improving the weft straightening effect on the fabric.

[0013] Fourth, through the rubber sleeve, the limiting roller can be in flexible contact with the fabric while increasing the friction force with the fabric, which is convenient for weft straightening the fabric in daily use. Brief Description of the Drawings

Guide chute one 201 is opened on the left side of the inner walls of the front and rear sides of the frame 101, and guide chute two 202 is opened on the right side of the inner walls of the front and rear sides of the frame 101. A first sliding plate 203 is slidably provided between the two guide chute one 201, and a second sliding plate 204 is slidably provided between the two guide chute two 202. Two warp straightening frames 205 symmetrically distributed front and rear are rotatably provided on the lower surface of the first sliding plate 203 and the upper surface of the second sliding plate 204. An electric drive module for driving the movement of the limiting roller 106 is further provided on the frame 101, and an electric control module for driving the movement of the warp straightening frame 205 is further provided on the frame 101.

[0022] As Figure 1 , 2 , as shown in Figures 5, 6, 4, the electric drive module includes a first dual-axis motor 108 uniformly provided on the inner walls of the front and rear sides of the frame 101. A first adjusting screw 107 is rotatably provided between two vertically adjacent first supports 103. The outer sides of the first adjusting screws 107 are respectively threadedly connected to the adjacent movable seats 105. The output shafts of the first dual-axis motor 108 are respectively fixed to the adjacent first adjusting screws 107 through couplings; Two driving motors two 206 symmetrically distributed front and rear are provided on the lower surface of the first sliding plate 203 and the upper surface of the second sliding plate 204. The output shafts of the driving motors two 206 are respectively fixed to the adjacent warp straightening frames 205 through couplings.

[0023] As Figure 2 , 3, as shown in Figures 4, the electric control module includes drive boxes 207 arranged on the front and rear sides of the frame 101. Four vertically evenly distributed second supports 208 are arranged inside each drive box 207. Slide rails 209 are respectively arranged between two vertically adjacent second supports 208. Connecting plates 210 are slidably arranged on the outer sides of the slide rails 209. The lower surface of the first sliding plate 203 and the upper surface of the second sliding plate 204 are respectively fixedly connected to the adjacent connecting plates 210.

[0025] When the fabric needs to be rectified during the processing of the fabric, the operator passes the fabric to be rectified through the limiting rollers 106 on the upper and lower sides, and then the control panel 301 adjusts the synchronous operation of the first dual-axis motor 108. As a result, the output shafts of the first dual-axis motor 108 drive the adjusting lead screws 107 connected thereto to rotate respectively, causing the adjusting lead screws 107 to drive the movable seats 105 threadedly connected thereto to slide between the two guide rails 104, so that the movable seats 105 on the upper and lower sides drive the limiting rollers 106 to move closer to each other to contact and limit the fabric; the control panel 301 adjusts the synchronous operation of the two second dual-axis motors 212, and then the output shafts of the second dual-axis motors 212 drive the adjusting lead screws 211 connected thereto to rotate respectively. Through the threaded relationship between the adjusting lead screws 211 and the connecting plates 210, the connecting plates 210 on the upper and lower sides slide outside the slide rails 209, so that the connecting plates 210 on the upper and lower sides move closer to each other, driving the first sliding plate 203 to slide downward between the two first guiding chutes 201 and the second sliding plate 204 to slide upward between the two second guiding chutes 202, so that the two fabric rectifying frames 205 on the left side press the fabric downward and the two fabric rectifying frames 205 on the right side press the fabric upward. The control panel 301 drives the first driving motor 109 and the second driving motor 206 to operate, so that the output shafts of the first driving motor 109 drive the limiting rollers 106 connected thereto to rotate respectively. Through the rotation of the limiting rollers 106, the fabric located between the limiting rollers 106 on the upper and lower sides is conveyed, and the output shafts of the second driving motor 206 drive the fabric rectifying frames 205 connected thereto to rotate respectively. Through the rotation of the fabric rectifying frames 205, the fabric during the conveying process is rectified. Through the cooperation of the fabric rectifying frames 205 on the left and right sides, the fabric can be rectified from multiple directions, effectively improving the fabric rectifying effect.
