The slide bar 24 is a "T"-shaped rod, and the frame has a "T"-shaped hole that cooperates with the "T"-shaped rod.

[0023] The driver 23 is a motor, which drives the slide bar 24 to move through multiple rocker arms. The two ends of the first rocker arm 25 are respectively rotatably connected to the output shaft of the motor and one end of the second rocker arm 26, and the other end of the second rocker arm 26 is rotatably connected to the slide bar 24. Of course, the driver 23 can also be a cylinder, which directly drives the "V"-shaped push head 22 to move linearly. There is a "V"-shaped blanking port 211 and a "V"-shaped shaping piece 212 on the plate surface of the shaping plate 21.

[0025] Specifically, the washboard 4 can slide along the rubbing belt 3 and can also be lifted and lowered vertically, and the sliding washboard 4 and the stationary rubbing belt 3 cooperate to twist the "V-shaped" fabric strips pressed between them into twists. A slide seat 6 is also provided above the rubbing belt 3. The slide seat 6 is slidably arranged on the slide rail 72 through a slider 71 and driven to slide by a first driving member 81. The first driving member 81 can be a cylinder, an electric cylinder, or a magnetic slide rail. The washboard 4 is connected below the slide seat 6 and slides synchronously with the slide seat 6. A second driving member 82 that can drive the lifting action of the washboard 4 is also provided on the slide seat 6. The second driving member 82 can be a cylinder, an electric cylinder, or a motor drives the washboard 4 to lift and lower through a screw nut structure. Of course, the washboard 4 can also not slide, and the rubbing belt movement and the stationary washboard cooperate to twist the twist. Slide rails 72 are provided on both sides of the rubbing belt 3. The slide rails 72 are "T"-shaped rails and the sliders are "T"-shaped blocks. The slide rails 72 are arranged along the rubbing belt transportation direction.

[0026] Specifically, the conveyor belt 1 and the rubbing belt 3 are arranged in parallel, the downstream end of the conveyor belt 1 is connected with the upstream end of the rubbing belt 3, the shaping plate 21 is located upstream of the rubbing belt 3, and the rubbing plate 4 is relatively downstream of the shaping plate 21, the shaping plate 21 is flush with the surface of the conveyor belt 1, the "V"-shaped opening of the shaping piece 212 faces the side of the conveyor belt 1, the fabric strip bending mechanism 2 is located on one side of the conveyor belt 1, the "V"-shaped pushing head 22 corresponds to the "V"-shaped opening of the shaping piece 212, and can push the fabric strip on the conveyor belt 1 toward the shaping plate 21 side.

[0027] Specifically, a sensing probe A91 is further provided upstream of the “V”-shaped pusher 22. After the sensing probe A91 senses the fabric strip on the conveyor belt 1, the driver 23 is controlled to delay operation, and the conveyor belt 1 continues to drive the fabric strip forward for a certain distance, and then the driver 23 drives the “V”-shaped pusher 22 to extend, so as to push the fabric strip onto the shaping plate 21. Alternatively, the sensing probe A91 is provided corresponding to the “V”-shaped pusher 22, so that the driver 23 does not need to delay, and after sensing the fabric strip on the conveyor belt 1, the driver 23 is directly controlled to work and drive the “V”-shaped pusher 22 to extend.

[0028] Specifically, a sensing probe B92 is provided under the shaping plate. After the sensing probe B92 senses the "V-shaped" fabric strip of the rubbing belt, the driving motor of the rubbing belt 3 is controlled to stop with a delay, so that the rubbing belt 3 continues to drive the "V-shaped" fabric strip forward for a certain distance and can move under the corresponding position of the rubbing board 4. Then, the rubbing board 4 is controlled to descend to contact the "V-shaped" fabric strip, and then the rubbing board 4 slides downstream.

[0029] The two ends of the conveyor belt 1 are supported by rollers, and a motor drives one of the rollers to rotate, thereby driving the conveyor belt 1 to move. The belt twisting movement is the same as that of the conveyor belt. The induction probe is of conventional structure.

[0030] The fabric strip bending mechanism of the utility model is simple and convenient for forming a "V-shaped" fabric strip. When in use, the fabric strip is first conveyed by the conveyor belt 1. After the induction probe A91 senses the fabric strip on the conveyor belt 1, the driver 23 is controlled to delay the operation, and the conveyor belt 1 continues to drive the fabric strip forward for a section. Then, the driver 23 drives the "V"-shaped push head 22 to extend through the rotation transmission of multiple rocker arms, and pushes the fabric strip onto the shaping plate 21. The "V"-shaped push head 22 cooperates with the "V"-shaped shaping piece 212 to squeeze the fabric strip. The "V"-shaped push head 22 is used to squeeze the inner side of the fabric strip, and the "V"-shaped shaping piece 212 is used to squeeze the outer side of the fabric strip, so that the fabric strip is bent into a "V shape", and the formed "V-shaped" fabric strip can just pass through the "V-shaped" drop port 211 to fall onto the rubbing belt 3 below. Then, the driver 23 drives the "V"-shaped push head 22 to slide and retract, waiting for the next operation.

[0031] The "V-shaped" fabric strip is conveyed by the rubbing belt 3. After the sensing probe B92 senses the "V-shaped" fabric strip of the rubbing belt 3, the driving motor of the rubbing belt 3 is controlled to stop with a delay, which will cause the rubbing belt 3 to drive the "V-shaped" fabric strip to continue to move forward a section to the bottom of the rubbing board 4. Then, the second driving component 82 is controlled to drive the rubbing board 4 to descend and contact the "V-shaped" fabric strip. Then, the first driving component 81 is controlled to drive the slide 6 and the rubbing board 4 to slide downstream together. The sliding rubbing board 4 and the stationary rubbing belt 3 can cooperate to drag the "V-shaped" fabric strip between them and twist it into a twist. Then, the second driving component 82 drives the rubbing board 4 to rise, and the first driving component 81 drives the slide 6 and the rubbing board 4 to slide back upstream together, waiting for the next operation.

[0032] The curvature of the "V-shaped" shaping piece 212 can be adjusted to shape the desired "V-shaped" fabric strip. When in use, the adjusting plate 51 is loosened by the locking head of the locking pin 52, and the shaping piece 212 can move in the blanking opening 211 to adjust its curvature. The rod of the locking pin 52 can slide relatively in the long groove, and then the locking head of the locking pin 52 presses against the adjusting plate 51 to lock it, and the shaping plate 212 connected to the adjusting plate 51 is also fixed.
