[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1-3 As shown, a cutting machine for knitted fabrics comprises: a feed roller group, a guide roller 1, a cutting roller group, a pressure roller group, a striping grid 2, and a discharge roller group.

[0017] The feed roller group includes a plurality of feed rollers 3, and the plurality of feed rollers 3 are arranged in an inclined manner. The guide roller 1 is arranged obliquely above the feed roller group. The knitted fabric rotates around the plurality of feed rollers 3 and the guide roller 1 in an S shape. The guide roller 1 has a larger diameter than the feed roller 3, so that the knitted fabric has a larger bending angle when entering the guide roller 1, so that the knitted fabric has a relatively flat surface when entering the cutting roller group. The function of the plurality of feed rollers 3 is to tension and flatten the knitted fabric, so that the knitted fabric has a relatively flat surface when entering the cutting roller group.

[0018] The cutting roller group includes an upper cutting roller 4 and a lower cutting roller 5, and a plurality of circular knives 6 are arranged at intervals on the upper cutting roller 4 and the lower cutting roller 5. A fabric support plate 7 is arranged between the upper cutting roller 4 and the lower cutting roller 5. The corresponding circular knives 6 on the upper cutting roller 4 and the lower cutting roller 5 have overlapping parts, and the upper cutting roller 4 rotates clockwise and the lower cutting roller 5 rotates counterclockwise to cut the knitted fabric. The fabric support plate 7 is provided with notches corresponding to the circular knives 6.

[0019] The rotation direction of the upper cutting roller 4 and the lower cutting roller 5 causes the cut waste and yarn to splash forward, so: a waste guide plate assembly is arranged in front of the upper cutting roller 4, and the waste guide plate assembly includes a plurality of waste guide plates 8 and a waste guide plate mounting rod 9, each of the waste guide plates 8 is obliquely arranged between two adjacent circular knives 6, and the waste guide plate 8 is fixedly mounted on the waste guide plate mounting rod 9; in addition, a waste baffle 10 is also arranged on the front side of the upper cutting roller 4.

[0020] The pressing roller group includes an upper pressing roller 11 and a lower pressing roller 12, and the fabric support plate 7 is provided with a slot for the lower pressing roller 12 to pass through. Both ends of the lower pressing roller 12 are connected to the lower pressing roller mounting frame through springs, and the springs make the lower pressing roller 12 have a tendency to move upward, so that the lower pressing roller 12 presses the knitted fabric toward the upper pressing roller 11.

[0021] The striping grid 2 is arranged behind the pressing roller group, and the striping grid 2 includes a plurality of grids for the cut knitted fabric strips to pass through.

[0022] The discharge roller group is arranged behind the discharge grid, and the discharge roller group includes two discharge rollers 13, and the two discharge rollers 13 are arranged in the horizontal direction.

[0023] A set of transmission gears are respectively installed at the ends of the upper pressing roller 11 , the upper cutting roller 4 , the lower cutting roller 5 , and the guide roller 1 , and each set of transmission gears is connected through a synchronous belt or meshing transmission with each other. One set of transmission gears is connected to a driving motor 14 .
