[0030] like Figures 1-6As shown, the embodiment of the present invention provides a slitting machine for producing flexible circuit boards, comprising: a conveyor 1, a top plate 8 and a lower plate 9, the bottom ends of both sides of the conveyor 1 are fixedly connected to fixed seats 6, the upper ends of the two fixed seats 6 are fixedly installed with electric telescopic rods 7, the lower ends of the top plates 8 are fixed to the telescopic ends of the two electric telescopic rods 7, a plurality of fixed strips are fixedly connected at the edge position of the lower end of the top plate 8, the upper ends of the lower plates 9 are fixedly connected to the lower ends of the plurality of fixed strips, one side of the lower plate 9 is fixedly connected to a fixed plate, the upper end of the fixed plate is fixedly installed with a telescopic cylinder 18, the telescopic end of the telescopic cylinder 18 is fixedly installed with a moving strip, and a sliding bar is provided on the side of the moving strip away from the telescopic cylinder 18 The movable groove is slidingly connected to the sliding groove, and the inner walls of the multiple pulleys 12 are rotatably connected to the L-shaped plates 11. A limit ring 13 is fixedly installed on each group of L-shaped plates 11, and a connecting rod 14 is fixedly installed on the bottom of each group of limit rings 13. The upper ends of the multiple connecting rods 14 pass through the upper ends of the multiple groups of L-shaped plates 11, and the lower ends of each group of connecting rods 14 are fixedly installed with a base 15. A cutting knife 16 is fixedly installed inside each group of bases 15. The multiple groups of cutting knives 16 are parallel to each other. The upper end of the lower plate 9 is penetrated by an adjustment hole 17 equal to the number of the L-shaped plates 11. The multiple adjustment holes 17 are composed of a first straight end, an oblique section, and a second straight end that are connected in sequence, and the multiple adjustment holes 1 7 is in a shape dispersed in the direction away from the moving bar as a whole, and the spacing between two adjacent groups of second straight sections is greater than the distance between two adjacent groups of first straight sections. The top of the lower plate 9 is slidably connected to a sliding bar 10, and a long hole 19 is opened through the upper end of the sliding bar 10. The side walls of multiple groups of connecting rods 14 are slidably connected to the inside of the long hole 19, and the multiple groups of connecting rods 14 are slidably connected to the inside of the multiple groups of adjusting holes 17. By starting the telescopic cylinder 18, the telescopic end of the telescopic cylinder 18 is extended, further pushing the moving bar and the multiple groups of pulleys 12 and the L-shaped plate 11 to move, thereby driving the limit ring 13, the connecting rod 14, the card seat 15 and the cutting knife 16 to move in the direction away from the moving bar, and the long hole 19 is in the multiple The plurality of connecting rods 14 slide along the upper end of the lower plate 9 under the pushing action. Because the long holes 19 on the movable bar and the sliding bar 10 cooperate to limit the plurality of connecting rods 14, the plurality of connecting rods 14 are arranged on a straight line parallel to the long holes 19, and the plurality of cutting knives 16 always remain parallel to each other. At the same time, in the process of moving the plurality of connecting rods 14, because the shape of the plurality of adjusting holes 17 has a guiding effect on the connecting rods 14, when the plurality of connecting rods 14 slide to the oblique end in the adjusting hole 17, the spacing between the plurality of connecting rods 14 gradually increases and the distance between each other remains consistent, and the distance between the plurality of cutting knives 16 can be quickly adjusted, thereby facilitating precise adjustment of the strip width.

[0031] like Figures 1-6As shown, in this embodiment, mounting shafts 2 are provided on both sides of the upper end of the conveyor 1, and an arc-shaped plate 4 is fixedly connected to the middle position of the side wall of the mounting shaft 2. Connecting ears 5 are fixedly connected to the end positions of both sides of the upper end of the conveyor 1, and the two ends of the side wall of the arc-shaped plate 4 are rotatably connected to the inner walls of the two connecting ears 5 respectively. One end of the two groups of arc-shaped plates 4 is fixedly connected to a handle 3, the lower end of the cutting knife 16 is arc-shaped, and the two handles 3 are provided with anti-slip stripes. The length of the long hole 19 is equal to the length of the lower plate 9, and both ends of the adjustment hole 17 are semicircular. The top plate 8 and the lower plate 9 are provided with corners away from the moving bar. It is provided with an angle, and the length of the cutting blade 16 is equal to the length of the card seat 15. Holding the handle 3 by hand and rotating it toward the two ends close to the conveyor 1, the mounting shaft 2 can be driven to rotate, and the two curved plates 4 are further opened upward, so as to facilitate the placement of the flexible circuit board on the conveyor 1. Then, the handle 3 is released, so that the two sets of handles 3 are placed on both sides of the conveyor 1 under the action of gravity. The gap between the curved plate 4 and the conveyor 1 just allows the flexible circuit board to pass through, so that the flexible circuit board can be prevented from warping on both sides when cutting the flexible circuit board, making it convenient for the conveyor 1 to convey the flexible circuit board to the lower end of the multiple sets of cutting blades 16 for cutting.

[0032] The technical solution provided by the present invention is that before using the slitting machine, the distance between the cutting knives 16 needs to be adjusted. First, by starting the telescopic cylinder 18, the telescopic end of the telescopic cylinder 18 is extended, further pushing the moving bar and the multiple sets of pulleys 12 and the L-shaped plate 11 to move, thereby driving the limit ring 13, the connecting rod 14, the card seat 15 and the cutting knife 16 to move away from the moving bar, and the long hole 19 slides along the upper end of the lower plate 9 under the pushing action of the multiple sets of connecting rods 14, because the long holes 19 on the moving bar and the sliding bar 10 cooperate with the multiple sets of Due to the limiting function of the connecting rod 14, multiple groups of connecting rods 14 are arranged on a straight line parallel to the long hole 19, and multiple groups of cutting knives 16 always remain parallel to each other. At the same time, in the process of moving multiple groups of connecting rods 14, because the shape of multiple groups of adjustment holes 17 has a guiding effect on the connecting rods 14, when multiple groups of connecting rods 14 slide to the oblique end in the adjustment hole 17, the spacing between multiple groups of connecting rods 14 gradually increases and the distance between each other remains consistent, the distance between multiple groups of cutting knives 16 can be quickly adjusted, thereby facilitating precise adjustment of the strip width.

[0033] Then, hold the handle 3 with your hand and rotate it towards the two ends of the conveyor 1, which can drive the installation shaft 2 to rotate, and further open the two curved plates 4 upward, so as to facilitate placing the flexible circuit board on the conveyor 1, and then release the handle 3, so that the two sets of handles 3 are placed on both sides of the conveyor 1 under the action of gravity. The gap between the curved plate 4 and the conveyor 1 just allows the flexible circuit board to pass through, so as to prevent the two sides of the flexible circuit board from warping when cutting the flexible circuit board, and facilitate the conveyor 1 to convey the flexible circuit board to the lower end of the multiple sets of cutting knives 16 for cutting.

To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
