[0009] The distance between two adjacent fixed clamping blocks is equal to the distance between two adjacent movable clamping blocks;

[0010] At least two fixed clamping blocks are vertically aligned with the movable clamping blocks at any time.

[0011] The feeding conveyor belt is tensioned on two left and right arranged first belt pulleys. The first belt pulleys are hinged on the frame, and a first motor for driving one of the first belt pulleys to rotate is arranged on the frame;

[0012] The follow-up conveyor belt is tensioned on two left and right arranged second belt pulleys. The second belt pulleys are hinged on the frame, and a fifth motor for driving one of the second belt pulleys to rotate is arranged on the frame; The linear speeds of the follow-up conveyor belt and the feeding conveyor belt are equal but in opposite directions;

[0013] The discharge conveyor belt is tensioned on two third pulleys arranged left and right. The third pulleys are hinged on the frame, and a second motor for driving one of the third pulleys to rotate is provided on the frame.

[0014] The right end of the discharge conveyor belt extends to the right side of the feed conveyor belt.

[0015] The support seat includes a plurality of stepped rods fixed on the follower conveyor belt. A plurality of stepped holes corresponding to the stepped rods one by one are formed on the movable clamping block. The stepped rods are inserted into the stepped holes, and a compression spring is clamped between the stepped surfaces of the stepped rods and the stepped surfaces of the stepped holes.

[0016] The cutting knife is hinged to the front end of the moving seat. The moving seat is slidably connected to a guide rail arranged in the front-back direction.

[0025] Embodiment, as shown in Figures 1 to 5 a double-sided printing and coloring scarf equal-length automatic cutting device, including a feed conveyor belt 11 rotating clockwise. A follower conveyor belt 21 and a discharge conveyor belt 31 rotating counterclockwise are respectively provided above and below the left end of the feed conveyor belt 11.

[0026] A plurality of fixedly clamped blocks 12 that are linearly and evenly distributed are fixed on the outer wall of the feeding conveyor belt 11, and a first magnet 13 is arranged inside the fixedly clamped block 12;

[0027] A plurality of support seats 22 that are linearly and evenly distributed are fixed on the follower conveyor belt 21. An elastically supported movable clamping block 23 is slidably connected to the support seat 22, and a second magnet 24 is fixed inside the movable clamping block 23;

[0028] A cutter 41 that can move back and forth is arranged between the feeding conveyor belt 11 and the follower conveyor belt 21.

[0029] Furthermore, the distance between two adjacent fixedly clamped blocks 12 is equal to the distance between two adjacent movable clamping blocks 23;

[0030] At least two fixedly clamped blocks 12 are arranged in an up-and-down alignment with the movable clamping blocks 23 at any time.

[0031] Furthermore, the feeding conveyor belt 11 is tensioned on two left-and-right arranged first belt pulleys 14. The first belt pulleys 14 are hinged on the frame 5, and a first motor for driving one of the first belt pulleys 14 to rotate is arranged on the frame 5;

[0032] The follower conveyor belt 21 is tensioned on two left-and-right arranged second belt pulleys 25. The second belt pulleys 25 are hinged on the frame 5, and a fifth motor for driving one of the second belt pulleys 25 to rotate is arranged on the frame 5; The linear speeds of the follower conveyor belt 21 and the feeding conveyor belt 11 are equal but in opposite directions;

[0033] The discharging conveyor belt 31 is tensioned on two left-and-right arranged third belt pulleys 32. The third belt pulleys 32 are hinged on the frame 5, and a second motor for driving one of the third belt pulleys 32 to rotate is arranged on the frame 5.

[0034] Furthermore, the right end of the discharging conveyor belt 31 extends to the right side of the feeding conveyor belt 11.

[0035] Furthermore, the support seat 22 includes a plurality of stepped rods 221 fixed on the follower conveyor belt 21. A plurality of stepped holes 231 corresponding to the stepped rods 221 one by one are formed on the movable clamping block 23. The stepped rods 221 are inserted into the stepped holes 231, and a compression spring 26 is clamped between the stepped surfaces of the stepped rods 221 and the stepped surfaces of the stepped holes 231.

[0036] Furthermore, the cutting knife 41 is hinged to the front end of the moving seat 42. The moving seat 42 is slidably connected to a guide rail 43 arranged in the front-rear direction. The guide rail 43 is fixedly connected to the machine frame 5. Above the guide rail 43, there is a screw rod 44 arranged parallel to it. The rear end of the moving seat 42 is screwed onto the screw rod 44. Both ends of the screw rod 44 are hinged to the machine frame 5. On the machine frame 5, there is a third motor 46 for driving the screw rod 44 to rotate.

[0037] On the moving seat 42, there is a fourth motor 45 for driving the cutting knife 41 to rotate.

[0038] Working principle: The first motor and the fifth motor are synchronously started and are in intermittent transmission. The first motor drives the feeding conveyor belt to rotate clockwise through the first pulley 14. The feeding conveyor belt drives the fixed clamping block 12 to rotate clockwise. The fifth motor drives the following conveyor belt 21 to rotate counterclockwise through the second pulley 25. The following conveyor belt 21 drives the movable clamping block 23 to rotate counterclockwise. When the movable clamping block 23 rotates to directly above a corresponding fixed clamping block 12, due to the mutual attraction of the first magnet and the second magnet, the movable clamping block 23 moves downward to clamp the scarf fabric 9, and then the scarf fabric 9 is moved forward to the right. When the second movable clamping block 23 moves to above the corresponding fixed clamping block 12, the movable clamping block approaches the fixed clamping block to clamp both ends of the scarf fabric. The first motor and the fifth motor stop rotating. At this time, the state is as Figure 1 shown;

[0039] Then, the third motor 46 and the fourth motor 45 are started. The fourth motor 45 drives the cutting knife 41 to rotate. The third motor 46 drives the screw rod 44 to rotate. The screw rod 44 drives the moving seat 42 to move forward. The moving seat 42 drives the cutting knife 41 to move forward, thereby cutting the scarf fabric; the moving seat moves backward and resets.

[0040] Then, the first motor and the fifth motor continue to rotate. The rightmost movable clamping block is separated from the corresponding fixed clamping block under the traction of the following conveyor belt 21. The feeding conveyor belt conveys the cut scarf 91 to the right. The scarf 91 then slides onto the discharging conveyor belt 31 and is output through the discharging conveyor belt.

[0041] Finally, the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Those of ordinary skill in the relevant technical field can also make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention shall be defined by the claims.
