Description

Technical Field

[0001] This utility model relates to the field of fabric textiles, and in particular to a fabric inspection machine unwinding frame. Background Technology

[0002] After the fabric is woven, it needs to be inspected using a fabric inspection machine. This is done by placing the fabric roll on the unwinding frame and then pulling the fabric through the light inspection area. The fabric is inspected in the inspection area, and after inspection, the rewinding mechanism rolls up the fabric. Generally, the unwinding frame is connected to two rotating rollers, with the fabric roll located in the upper part between the two rollers. The fabric roll rotates to release the fabric, and at the same time, the rotation of the fabric roll drives the rotating rollers to rotate, reducing the friction between the fabric roll and the rotating rollers and increasing the unwinding speed. However, the relatively large contact area between the fabric roll and the rotating rollers affects the unwinding speed. Utility Model Content

[0003] The purpose of this invention is to provide a fabric inspection machine unwinding frame, which has the advantage of reducing friction between the fabric roll and the unwinding frame and increasing the rotation speed of the fabric roll.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A fabric inspection machine unwinding frame includes a fabric inspection machine. A support frame is provided in the unwinding area behind the fabric inspection machine. There are two support frames, located on both sides behind the fabric inspection machine. A support is fixedly connected above the support frame. Two horizontal rotating shafts are fixedly connected to the support. Each of the two rotating shafts is fixedly connected to a bearing. The inner ring of the bearing is fixedly connected to the rotating shaft, and a wheel is fixedly connected to the outer ring of the bearing. The support is provided with a limit mechanism.

[0006] Using the above technical solution, the fabric roll is placed on the support frame, with the end of the roll rod positioned above the two rotating rollers. The fabric is then pulled out and passed through the light inspection area of ​​the fabric inspection machine before being connected to the winding mechanism. The rod is then limited by a limiting mechanism. The winding mechanism pulls the fabric roll and the rod to rotate, and the rod drives the rotating rollers to rotate. The contact area between the rod and the rotating rollers is smaller than the contact area between the fabric roll and the rollers. At the same time, the friction between the rod and the rotating rollers is also less than the friction between the fabric roll and the rollers, thereby increasing the rotation speed.

[0007] Preferably, the limiting mechanism includes a groove plate and a connecting seat. Two groove plates are respectively fixedly connected to both sides of the support. The groove plate has a sliding groove, which includes a vertical waist-shaped groove and an arc groove with an appropriate radius centered at the upper end of the waist-shaped groove. The connecting seat is connected to two bearings and a rotating wheel with the same structure as the support. Connecting rods are fixedly connected to both sides of one end of the connecting seat. The connecting rods rotate to produce two rotors. The length between the two rotors is equal to the radius of the arc groove. The two rotors are embedded in the sliding groove. A pin is fixedly connected to the other end of the connecting seat opposite to the connecting rod. The support is fixedly connected to a hole opposite to the pin.

[0008] Using the above technical solution, the end of the roll rod is placed above the two rotating wheels. When the two rotors of the connecting rod of the connecting seat are respectively embedded in the vertical waist-shaped groove and the arc groove of the slide, the connecting seat is rotated along the arc groove with the rotor located in the waist-shaped groove as the center. When the rotor in the arc groove rotates into the waist-shaped groove, the connecting seat can be moved vertically downward along the waist-shaped groove so that the two rotating wheels of the connecting seat contact the roll rod. At the same time, the pin of the connecting seat is inserted into the insertion hole of the support to prevent the cloth roll from falling off the support frame when rotating. Similarly, when the roll rod is removed, the connecting seat is first moved upward to separate the pin from the insertion hole, and then the connecting seat is rotated to move it away from the roll rod.

[0009] Preferably, the support frame is fixedly connected to a vertical support rod, the support rod is located on the side of the support, the support rod is rotatably connected to a bearing, and the bearing is fixedly connected to a wheel.

[0010] With the above technical solution, the end face of the roll rod contacts the surface of the second rotating wheel of the support rod. The rotation of the roll rod drives the second rotating wheel to rotate, preventing the roll rod and the fabric roll from shifting left and right during rotation, which would cause wrinkles in the fabric and affect the inspection of the fabric.

[0011] Preferably, the radius of the arc groove is greater than 90 degrees.

[0012] By adopting the above technical solution, when the connecting seat is separated from the coil rod, the connecting seat is in an inclined state to prevent the connecting seat from turning back and contacting the support, which would affect the placement of the coil rod.

[0020] See Figures 1 to 4 A fabric inspection machine unwinding frame includes the fabric inspection machine. A support frame 1 is provided at the rear unwinding area of ​​the fabric inspection machine. There are two support frames 1, located on opposite sides of the rear of the fabric inspection machine. A support base 2 is fixedly connected above each support frame 1. Two horizontal rotating shafts are fixedly connected to each support base 2. Bearings 3 are fixedly connected to the two rotating shafts respectively. The inner ring of bearing 3 is fixedly connected to the rotating shaft, and a rotating wheel 14 is fixedly connected to the outer ring of bearing 3. A vertical support rod 12 is fixedly connected to the support frame 1, located on the side of the support base 2. A bearing 13 is rotatably connected to the support rod 12, and a guide wheel 13 is fixedly connected to the bearing 13. Two slots are fixedly connected to each side of the support base 2. Plate 4, the groove plate 4 is provided with a sliding groove, the sliding groove includes a vertical waist-shaped groove 6 and an arc groove 7 with an appropriate length as the radius and the upper end of the waist-shaped groove 6 as the center, and the amplitude of the arc groove 7 is greater than 90 degrees. It also includes a connecting seat 5, the connecting seat 5 is connected to two bearings and a rotating wheel 14 with the same structure as the support 2. Connecting rods 8 are fixedly connected to both sides of one end of the connecting seat 5. The connecting rods 8 rotate to have two rotors 9. The length between the two rotors 9 is equal to the radius of the arc groove 7. The two rotors 9 are embedded in the sliding groove. The other end of the connecting seat 5 opposite to the connecting rods 8 is fixedly connected to a pin 10. The support 2 is fixedly connected to a socket 11 opposite to the pin 10.

[0021] Working principle: First, move the connecting seat 5 upward along the waist-shaped groove 6 to separate the pin 10 from the insertion hole 11. Then, rotate the connecting seat 5 along the arc groove 7 to move it away from the support 2. Place the fabric roll on the support frame 1 so that the end of the fabric roll rod 15 is located above the two rotating wheels 14 of the support 2. Then, move the connecting seat 5 so that the rotating wheels 14 contact the rod 15, and at the same time, make the pin 10 embed into the insertion hole 11 to prevent the rod 15 from falling off the support 2. Then, pull the fabric on the fabric roll through the light inspection area of ​​the fabric inspection machine and connect it to the winding mechanism. The winding mechanism pulls the fabric roll and the rod 15 to rotate and release the fabric. The reduced support area of ​​the winding frame on the fabric roll reduces friction and increases the rotation speed. When the rod 15 rotates, it is restricted by the support rods 12 on both sides and will not deviate to the left or right.
