Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1

[0026] Please refer to Figures 1 - 3 , an anti-weft skew device in a fabric shaping process, including a base 1. Inside the base 1, there is a driving and conveying mechanism 2 for conveying the fabric. Inside the driving and conveying mechanism 2, there is an anti-weft skew correction mechanism 3. Inside the anti-weft skew correction mechanism 3, there is a clamping mechanism 4. The driving and conveying mechanism 2 realizes the horizontal conveying of the fabric. Compared with the traditional belt drive, the use of the driving gear 21 and the transmission chain 22 greatly reduces the slipping phenomenon, avoids the weft skew of the fabric, and effectively improves the shaping quality of the fabric;

[0027] The driving and conveying mechanism 2 includes a biaxial motor 20 fixedly connected to the top of the base 1. The output ends of the biaxial motor 20 are fixedly connected with driving gears 21. The outside of the driving gears 21 is sleeved with transmission chains 22. The other end of the transmission chain 22 is sleeved with a driven gear 23. After the fabric is clamped by the clamping mechanism 4, the biaxial motor 20 is started, and the horizontal conveying plate 30 is conveyed through the driving gear 21 and the transmission chain 22, and the fabric is conveyed to the bottom of the heating component 6 for heating and shaping;

[0028] The anti-weft skew correction mechanism 3 includes a horizontal conveying plate 30 arranged inside the transmission chain 22. The top of the horizontal conveying plate 30 is fixedly connected with a plurality of limit racks 31. The limit racks 31 are engaged and adapted to the transmission chain 22. The rotation of the transmission chain 22 is limited by the limit racks 31 to realize the horizontal conveying of the horizontal conveying plate 30. Inside the horizontal conveying plate 30, a movable rod 32 is slidably installed, and an inclination detection component is arranged inside the horizontal conveying plate 30;

[0029] The clamping mechanism 4 includes a mounting plate 40 fixedly connected inside the movable rod 32. A clamping assembly for clamping the two end portions of the fabric is provided inside the mounting plate 40. When installing the fabric, place the two ends of the fabric on the clamping plates 41, and turn on the electric push rod 42 to move the top clamping plate 41 downward to clamp and position the fabric.

[0032] The tilt detection assembly includes buffer pads 33 fixed on both sides of the movable rod 32. Magnetic sliding rods 34 are fixedly connected to both sides of the movable rod 32. The magnetic sliding rods 34 are located inside the buffer pads 33. Elastic air bags 35 are fixedly connected to the side of the magnetic sliding rods 34 away from the movable rod 32. During the fabric conveying process, when the forces on both sides of the movable rod 32 are uneven, the elastic air bags 35 on both sides undergo different degrees of compression deformation;

[0033] A pressure detection ball 36 is provided at the center inside the elastic air bag 35. The pressure detection ball 36 is fixedly connected to the inner wall of the elastic air bag 35 through an elastic connecting rod 37. An electromagnet 38 is fixedly connected to the outside of the elastic air bag 35; when the side with greater pressure is received, the greater the pressure electrical signal on the pressure detection ball 36, and at this time the surface tilts more in this direction. The electromagnet 38 and the pressure detection ball 36 are electrically connected, and the pressure detection ball 36 transmits the detection result to the electromagnet 38. Specifically, according to the electrical signal on the pressure detection ball 36 on the side with greater pressure, control the current of the electromagnet 38 on this side to be less than that on the other side. At this time, the electromagnetic adsorption force on the side with a larger electrical signal is greater than the current side with a smaller electrical signal. At this time, the movable rod 32 moves towards the side with less force, thereby realizing the correction of the tilt and greatly reducing the weft skew phenomenon during the fabric conveying process.

After conveying and heat setting, the dual-axis motor 20 rotates in the reverse direction to make the fabric return to the initial position, and then turn on the electric push rod 42 to drive the top clamping plate 41 to lift, and take out the processed fabric;

[0035] As a preferred technical solution of this embodiment, a top plate 5 is fixedly connected to the top of the base 1, and a heating assembly 6 is provided on the top of the top plate 5; the bottom of the heating assembly 6 penetrates through the top plate 5 and is provided with a heating tube. After the fabric addition is completed, the mounting plate 40 conveys the clamped fabric to below the heating tube through the driving and conveying mechanism 2 for heating and shaping the fabric. After the shaping is completed, the mounting plate 40 moves horizontally to the initial position.
