Description

Technical Field

[0001] The utility model relates to the technical field of fabric cutting deviation correction, in particular to a deviation correction device for a fabric cutting machine. Background Technique

[0002] In the process of curtain production, cutting is required first. After leaving the factory, the fabric is a continuous whole roll. In order to reduce its size and facilitate cutting into different shapes, the fabric needs to be cut as a whole first.

[0003] The general cutting method is to lead the fabric from the fabric roll to the cutting table through a guide roller group, and then the cutting device cuts the fabric in a straight line. However, due to the thick gram weight and wide width of the curtain fabric, the width of the curtain is 2.8 meters, 3.2 meters, 3.4 meters, etc. During the process of traction and pulling, the fabric will sag and form an arc, resulting in uneven cutting edges of the fabric and affecting the product quality.

Specific embodiments

[0020] An embodiment of the utility model provides a deviation rectifying device for a cloth cutting machine. As Figures 1-3 shown, the cloth leading-out mechanism 3 and the cutting mechanism 4 are mature technologies existing in the cutting machine, and will not be described in detail here.

[0021] The present application adds a deviation rectifying device 1 between the cloth leading-out mechanism 3 and the cutting mechanism 4 of the cutting machine.

[0022] As Figure 1 and 2As shown in the figure, the deviation rectifying device 1 is installed on the cutting table of the cutting mechanism 4 through the fixing frame 5. The deviation rectifying device 1 includes a bracket 11 and a deviation rectifying shaft 12 arranged on the bracket 11. The bracket 11 is connected to the cutting table of the cutting mechanism 4 through the fixing frame 5. A deviation rectifying piece 14 is detachably arranged on the deviation rectifying shaft 12. The side of the deviation rectifying piece 14 facing the cutting mechanism 4 is a deviation rectifying arc edge 16, and the deviation rectifying arc edge 16 is in an arc shape protruding in the middle. The length of the deviation rectifying arc edge 16 is determined according to the width of the fabric 2, and its length needs to be greater than the width of the fabric 2.

[0023] By setting the deviation rectifying piece 14 with an arc shape protruding in the middle, the passing fabric 2 can be guided to spread and flatten from the middle to both sides, so that the fabric 2 entering the cutting mechanism 4 spreads out in the middle, effectively improving the flatness of the cutting edge.

[0024] As Figure 1 shown in the figure, an angle adjusting mechanism 5 for adjusting the angle of the deviation rectifying shaft 12 is arranged on the bracket 11. By setting the angle adjusting mechanism 5, the deviation rectifying piece 14 can be adjusted to a suitable angle according to the type and quality of the fabric 2, so as to reach the best deviation rectifying position.

[0025] As Figure 3 shown in the figure, the angle adjusting mechanism 5 includes a worm gear 51, a worm 52 and a handwheel 53 coaxially connected to the worm 52. The deviation rectifying shaft 12 is rotatably arranged on the bracket 11 through a bearing seat. The worm gear 51 is coaxially connected to the deviation rectifying shaft 12. The two ends of the worm 52 are arranged on the bracket 11 through bearing seats and mesh with the worm gear 51. By rotating the worm 52 to drive the worm gear 51 and the deviation rectifying shaft 12 to rotate, the angle adjustment of the deviation rectifying piece 14 is realized.

[0026] Guide rollers 13 for guiding the fabric 2 to enter and exit are arranged on the front and rear sides of the deviation rectifying shaft 12 on the bracket 11. The two ends of the guide roller 13 are rotatably arranged on the bracket 11 through bearing seats.

[0027] As Figure 3 shown in the figure, an installation base plate 17 is arranged along the length direction of the deviation rectifying shaft 12. Fixing holes 19 are arranged at intervals on the installation base plate 17. The deviation rectifying piece 14 is provided with a number of groove-shaped adjustment grooves 18 corresponding to the fixing holes 19 one by one. By setting the adjustment grooves 18, the distance that the deviation rectifying piece 14 extends out of the deviation rectifying shaft 12 can be adjusted. The fixing holes 19 and the adjustment grooves 18 are connected by locking bolts 20.

[0028] As Figure 3 shown in the figure, a pressing plate 21 for pressing the deviation rectifying piece 14 on the installation base plate 17 is further arranged at the middle position of the deviation rectifying shaft 12. The deviation rectifying piece 14 can be horizontally inserted between the pressing plate 21 and the installation base plate 17.
