[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 , a fixed roller auxiliary clamping claw, including a card base body 1, four sliding grooves are symmetrically opened around the center on the four sides of the top of the card base body 1, and sliding blocks 42 are movably arranged in the sliding grooves, and the tops of the sliding blocks 42 on the left and right sides of the top of the card base body 1 are respectively provided with short fixed roller clamping claw assemblies 24, and the tops of the short fixed roller clamping claw assemblies 24 are respectively provided with auxiliary high clamping claw assemblies 21, and the tops of the sliding blocks 42 on the front and rear sides of the top of the card base body 1 are respectively provided with high fixed roller clamping claw assemblies 23, and the tops of the high fixed roller clamping claw assemblies 23 are provided with auxiliary low clamping claw assemblies 22, and the high fixed roller clamping claw assemblies 23 and the short fixed roller clamping claw assemblies 24 are staggered.

[0023] In addition, a cavity is opened in the card seat body 1, and a fixed ring seat is set in the middle of the cavity. The outer wall of the fixed ring seat is movably provided with a gear ring 72 through a bearing assembly. The front card floating cylinder assembly 6 is provided outside the gear ring 72 and at the corresponding high fixed roller claw assembly 23 and low fixed roller claw assembly 24 in the cavity, and a swing arm gear assembly 5 is provided on one side of the front card floating cylinder assembly 6, and one side of the swing arm gear assembly 5 is connected to the sliding block 42.

[0024] At the same time, proximity switch components 31 are provided at both ends and the front side of the top of the card holder body 1 , and a reducer component 32 is provided at the bottom of one side of the card holder body 1 .

[0025] At the same time, the high fixed roller claw assembly 23 and the low fixed roller claw assembly 24 both include a fixed seat, two claw seats are equidistantly arranged on one side of the fixed seat, an eccentric shaft is arranged on one side of the claw seat, a roller is sleeved on the outer wall of the eccentric shaft, and an extended protrusion is arranged at the bottom of the fixed seat of the high fixed roller claw assembly 23.

[0026] In addition, the auxiliary low jaw assembly 22 and the auxiliary high jaw assembly 21 both include a base, an auxiliary jaw is obliquely arranged on the top of the base, a bearing is arranged on one side of the auxiliary jaw, and a roller is provided on the outer wall of the bearing, and the length of the auxiliary jaw of the auxiliary low jaw assembly 22 is greater than the length of the auxiliary jaw of the auxiliary high jaw assembly 21. It is worth noting that the inclination angle of the base and the auxiliary jaw is 45 degrees, and the 45-degree inclination design is adopted with reference to the swing of the cutting head of the whole machine by plus or minus 45 degrees to avoid interference between the jaw and the cutting head when cutting the groove. It is worth mentioning that the swing of the cutting head of the whole machine by plus or minus 45 degrees means that during the cutting process, the cutting head (that is, the part that performs the cutting action) can swing up and down or left and right at its basic position, and the swing angle range covers the entire interval from minus 45 degrees to plus 45 degrees.

[0027] Furthermore, the swing arm gear assembly 5 includes a swing arm shaft, the outer wall of the swing arm shaft is provided with a swing arm meshing sleeve at the gear ring 72, the outer wall of the gear ring 72 is provided with a tooth groove at the swing arm meshing position, the tooth groove is meshed with the swing arm for transmission, and a needle roller is provided in the gear ring 72;

The front card floating cylinder assembly 6 drives the connecting rod of the corresponding swing arm gear assembly 5 to rotate. When the connecting rod rotates, it drives its swing arm shaft to rotate, so that the swing arm rotates to a certain extent, thereby driving the corresponding sliding block to move, and when the swing arm shaft rotates, its swing arm engages with the tooth groove on the outer wall of the ring gear 72 for transmission.

[0030] It is also worth noting that after the auxiliary low claw assembly 22 and the auxiliary high claw assembly 21 are installed with the corresponding high fixed roller claw assembly 23 and the low fixed roller claw assembly 24, the rollers of the auxiliary low claw assembly 22 and the auxiliary high claw assembly 21 are located at the same height.
