[0046] Specifically, when the cardboard needs to be processed, the cardboard is placed between the mounting frames 1, and the distance between the adjustment portion 3 and the mounting frame 1 is changed according to the specifications of the cardboard, so as to adapt to cardboards of different specifications, increase the flexibility of the adjustment portion 3 in transporting the cardboard, and squeeze and fix the cardboard between the adjustment portion 3 and the mounting frame 1 to avoid the cardboard from being offset during the processing, thereby causing processing errors;

[0047] During the vertical movement of the adjusting part 3, the linkage part 5 can also move with the adjusting part 3. At the same time, the power of the linkage part 5 is always connected with the cutting part 4. Through the linkage part 5, it is ensured that the power of the linkage part 5 can adjust the horizontal position of the cutting part 4.

[0048] Then the driving part 2 drives the cardboard after being squeezed and fixed to move in the horizontal longitudinal direction, thus completing the movement of the cardboard;

[0049] When the cardboard is cut by the cutting part 4, the crankshaft 403 is driven to rotate by the rotation of the cutting motor 402, and the rotation of the crankshaft 403 drives the upper end of the shaft rod 404 to move in a circular path, so that the shaft rod 404 drives the sliding seat 405 at the lower end to reciprocate in the vertical direction of the driving housing 401, and the reciprocating movement of the sliding seat 405 drives the cutting cable 406 to reciprocate in the vertical direction;

[0050] During the reciprocating movement of the cutting cable 406 or the movement of the driving shell 401 driven by the adjustment part 3, the cutting cable 406 can pull the follower seat 409 inside the follower shell 407 to slide, and at the same time, the follower wheel 408 rotates during the movement of the cutting cable 406. The movement of the follower seat 409 causes the elastic reset member 4010 to elastically deform. Through the elastic characteristics of the elastic reset member 4010, the sliding seat 405 can always apply pressure to the cutting cable 406 to ensure the straightness of the cutting cable 406, and prevent it from bending due to the reciprocating movement of the cutting cable 406, thereby ensuring the stability of the cutting cable 406 during the cutting process.

[0051] See also Fig. 9 As shown, the crankshaft 403 is configured as a whole in the shape of a "X", and the middle part of the crankshaft 403 can drive the upper end of the shaft rod 404 to move in a circular path, so that the shaft rod 404 drives the sliding seat 405 at the lower end to reciprocate in the vertical direction of the drive housing 401, so that the sliding seat 405 drives the cutting cable 406 to reciprocate, so that the cutting cable 406 frictionally cuts the cardboard.

[0052] See also Figure 4 As shown, the driving unit 2 includes a driving motor 201, a driving wheel 202, a connecting belt 203 and a driving roller 204. The driving motor 201 is fixedly connected to the inside of the mounting frame 1. Two driving wheels 202 are provided, one of which is fixedly connected to the output end of the driving motor 201. The inner side of the connecting belt 203 contacts the outer edges of the two driving wheels 202. The driving roller 204 is rotatably arranged inside the mounting frame 1, and one end of the driving roller 204 is fixedly connected to the driving wheel 202.

[0053] The corresponding driving wheel 202 is driven to rotate by the driving motor 201, and the rotation of the driving wheel 202 transmits power to the other driving wheel 202 through the connecting belt 203, so as to achieve the simultaneous driving of the two driving wheels 202, so that the two driving wheels 202 drive the driving roller 204 to rotate in the same direction, so as to ensure the driving roller 204 to drive the cardboard to be transported.

[0054] See also Figure 2 as well as Figures 4 to 6As shown, the adjustment part 3 includes an adjustment seat 301, a follower roller 302, an extrusion plate 303, an elastic extrusion piece 304 and an extrusion cylinder 305. The adjustment seat 301 is slidably arranged inside the upper end of the mounting frame 1, the follower roller 302 is rotatably arranged at the lower end of the adjustment seat 301, the extrusion plate 303 is slidably arranged inside the adjustment seat 301, the elastic extrusion piece 304 is arranged between the adjustment seat 301 and the extrusion plate 303, the extrusion cylinder 305 is fixedly arranged inside the upper end of the mounting frame 1, and the output end of the extrusion cylinder 305 is fixedly connected to the extrusion plate 303;

[0055] The output end of the extrusion cylinder 305 drives the extrusion plate 303 and the adjustment seat 301 to move in the vertical direction together until the outer edge of the follower roller 302 contacts the cardboard at the lower end. At this time, the extrusion cylinder 305 drives the extrusion plate 303 to move downward so that the extrusion plate 303 squeezes the elastic extrusion member 304, and the elastic extrusion member 304 applies the extrusion to the adjustment seat 301, so that the follower roller 302 can be in closer contact with the cardboard. The pressure of the follower roller 302 on the cardboard can also increase the contact pressure between the cardboard and the driving roller 204, thereby ensuring the transportation of the cardboard.

[0056] See also Figure 2 as well as Figures 4 to 6 As shown, the follower roller 302 corresponds vertically to the outer edge of the driving roller 204, thereby ensuring that the vertical pressure applied by the follower roller 302 to the cardboard can accurately act on the outer edge of the driving roller 204, thereby ensuring stable transportation of the cardboard by the driving roller 204 and the follower roller 302.

[0057] See also Figure 6 As shown, the outer edges of the follower roller 302 and the driving roller 204 are provided with rubber sleeves, which can increase the friction between the follower roller 302 and the driving roller 204 and the surface of the cardboard, further ensuring the transportation of the cardboard by the driving roller 204 and the follower roller 302.

[0058] See also Figure 2 and Figure 4 As shown, a limiting groove is provided inside the adjustment seat 301, and the limiting groove cooperates with the two sides of the extrusion plate 303. The limiting groove provides guidance and limitation for the vertical movement of the extrusion plate 303, and can also prevent the extrusion plate 303 from destructive deformation when being squeezed by the extrusion cylinder 305, thereby enhancing the structural strength of the extrusion plate 303.

[0059] See also Figure 4 as well as Figures 6 to 10As shown, a limit block 4071 is fixedly provided on one side of the follower housing 407 and the driving housing 401, and the limit block 4071 is overall arranged in a T shape. Guide rails matching with the limit block 4071 are provided inside the mounting frame 1 and the adjusting seat 301. The guide rails are used to provide guidance and limitation for the follower housing 407 and the driving housing 401 when they move, so as to prevent the follower housing 407 and the driving housing 401 from shifting during the movement, thereby affecting the cutting accuracy of the cutting part 4.

[0060] See also Figure 2 , Figure 3 and Figure 5 As shown, the linkage part 5 includes a linkage motor 501, a rotating wheel 502, a rotating screw 503, a linkage rod 504, a connecting seat 505, a supporting wheel 506 and a linkage belt 507. The linkage motor 501 is fixedly arranged inside the mounting frame 1. Two rotating wheels 502 are provided, one of which is rotatably arranged inside the mounting frame 1, and the other rotating wheel 502 is rotatably arranged inside the adjusting seat 301.

The connecting seat 505 is threadedly connected, another rotating screw rod 503 is rotatably arranged inside the adjusting seat 301, the outer edge of this rotating screw rod 503 is threadedly connected to the inner thread of the driving housing 401, two linkage rods 504 are provided, and the inner part of one end of the linkage rod 504 is rotatably connected to the outer edge of the rotating screw 503, the upper and lower ends of the connecting seat 505 are both rotatably connected to the inner part of the other end of the corresponding linkage rod 504, and two supporting wheels 506 are rotatably arranged inside the connecting seat 505, the inner side of the linkage belt 507 is in contact with the outer edge of the rotating wheel 502 and one supporting wheel 506, the outer edge of the linkage belt 507 is in contact with the outer edge of the other supporting wheel 506, and the linkage belt 507 is bent;

[0061] The corresponding rotating wheel 502 is driven to rotate by the rotation of the linkage motor 501, and the rotation power of the rotating wheel 502 is transmitted to the other rotating wheel 502 through the linkage belt 507. The rotation of the two rotating wheels 502 can drive the corresponding rotating screw 503 to rotate. The position of the threaded cutting part 4 is adjusted by the rotation of the rotating screw 503, so as to adjust the cutting position of the cutting part 4 and increase the flexibility of the cutting part 4 in cutting paperboards.

[0062] When the adjusting seat 301 moves in the vertical direction, the adjusting seat 301 drives the corresponding rotating wheel 502 to move, so that the rotating wheel 502 and the rotating screw 503 drive the corresponding linkage rod 504 to move, so that the linkage rod 504 drives the connecting seat 505 at the other end to move, and the movement of the connecting seat 505 drives the other linkage rod 504 to rotate, so that the connecting seat 505 is always between the two rotating wheels 502, ensuring that the linkage belt 507 does not rotate during the movement of the adjusting seat 301, thereby ensuring the accuracy of the linkage belt 507 driving the rotating wheel 502, and further ensuring the cutting quality of the cardboard by the cutting part 4.

[0063] See also Figure 7 As shown, the threads of the outer edges of the two ends of the rotating screw 503 are in opposite directions. During the rotation of the rotating screw 503, the two cutting parts 4 can be driven to move toward or away from each other, so that the cutting shapes of the two ends of the cardboard are the same, ensuring the cutting quality of the cardboard.

[0064] The working principle of the present invention is as follows: when the cardboard needs to be processed, the cardboard is placed between the mounting frames 1, and the distance between the adjustment portion 3 and the mounting frame 1 is changed according to the specifications of the cardboard to adapt to cardboards of different specifications, and the cardboard between the adjustment portion 3 and the mounting frame 1 is squeezed and fixed to avoid the cardboard from being offset during the processing, thereby causing processing errors;

[0065] During the vertical movement of the adjusting part 3, the linkage part 5 can also move with the adjusting part 3. At the same time, the power of the linkage part 5 is always connected with the cutting part 4. Through the linkage part 5, it is ensured that the power of the linkage part 5 can adjust the horizontal position of the cutting part 4.

[0066] Then the driving part 2 drives the cardboard after being squeezed and fixed to move in the horizontal longitudinal direction, thus completing the movement of the cardboard;

[0067] When the cardboard is cut by the cutting part 4, the crankshaft 403 is driven to rotate by the rotation of the cutting motor 402, and the rotation of the crankshaft 403 drives the upper end of the shaft rod 404 to move in a circular path, so that the shaft rod 404 drives the sliding seat 405 at the lower end to reciprocate in the vertical direction of the driving housing 401, and the reciprocating movement of the sliding seat 405 drives the cutting cable 406 to reciprocate in the vertical direction;

[0068] During the reciprocating movement of the cutting cable 406 or the movement of the driving shell 401 driven by the adjustment part 3, the cutting cable 406 can pull the follower seat 409 inside the follower shell 407 to slide, and at the same time, the follower wheel 408 rotates during the movement of the cutting cable 406. The movement of the follower seat 409 causes the elastic reset member 4010 to elastically deform. Through the elastic characteristics of the elastic reset member 4010, the sliding seat 405 can always apply pressure to the cutting cable 406 to ensure the straightness of the cutting cable 406, and prevent it from bending due to the reciprocating movement of the cutting cable 406, thereby ensuring the stability of the cutting cable 406 during the cutting process.
