Breadth edge-cutting device

Abstract

The invention discloses a breadth edge-cutting device with quite convenient operation and quite easy regulation, which comprises a pair of parallel fixed seats and a pair of knife seats with cutting knives, wherein a square supporting shaft and a distance-regulating lead screw shaft which are mutually parallel are movably penetrated between the pair of fixed seats, reverse threads are arranged at both ends of the distance-regulating lead screw shaft, a guide rod parallel to the distance-regulating lead screw shaft is also arranged on each fixed seat, a supporting hole matched with the cross section of the supporting shaft is arranged on the supporting ear of each knife seat, each knife seat is movably penetrated on the supporting shaft through the supporting hole, a distance-regulating thread sleeve is respectively sleeved on the distance-regulating threads at both ends of the distance-regulating lead screw shaft, and the supporting ear of each knife seat is clamped between a pair of limiting edges of the corresponding distance-regulating thread sleeve; and a worm wheel-worm case is arranged on one fixed seat, a worm wheel and a worm which are mutually matched are arranged in the worm wheel-worm case, the worm wheel is connected with the end part at one corresponding side of the supporting shaft, and a cutting-knife fine-adjusting mechanism is arranged between each knife seat and each cutting knife. The invention is mainly used on flow lines for producing sheet materials, coiled materials and the like.

Description

technical field [0001] The invention relates to a width trimming device used on production lines such as sheets and rolls. Background technique [0002] At present, in the production line of sheet material, coil material, etc., usually adopt figure 1 Width cutter unit shown. In actual use, when adjusting the width (adjusting the lateral distance between the cutters), both ends need to be adjusted separately, that is: adjust the cutter mechanism 1 on the left through the distance adjustment hand wheel 3 on the left, and adjust the cutter mechanism 1 on the left through the distance adjustment handwheel 3 on the right. Adjust the distance adjustment handwheel 4 to adjust the cutter mechanism 2 on the right; If the speed or distance is different, the pair of transverse guide rods 7 and 8 will be inclined, and the pair of vertical moving plates 9 and 10 and the corresponding pair of vertical guide rods 11 and 12 will easily get stuck. The operation must be very careful, so tha...

Problems solved by technology

In actual use, when adjusting the width (adjusting the lateral distance between the cutters), both ends need to be adjusted separately, that is: adjust the cutter mechanism 1 on the left through the distance adjustment handwheel 3 on the left, and adjust the cutter mechanism 1 on the left through the distance adjustment hand wheel on the right. Adjust the distance adjustment handwheel 4 to adjust the cutter mechanism 2 on the right side; when lowering the knife, two people need to adjust the lower knife handwheel 5 on the left and the lower knife handwheel 6 on the right at the same time. If the speed or distance is different, the pair of transverse guide rods 7 and 8 will be tilted, and the pair of vertical moving plates 9 and 10 and the corresponding pair of vertical guide rods 11 and 12 will be easily stuck, so the operation must be very careful, so that the operation The staff is very tiring and the labor intensity is high

In summary, the operation of this width cutter device is very troublesome and the work efficiency is low
