Detailed Embodiment

[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] The following describes the specific implementation of the present utility model in detail in conjunction with specific embodiments.

[0023] As Figures 1-6 shown, a cutting device for magnetic strip processing includes a hand plate 1. The front end of the hand plate 1 has a guide groove 11. Two limiting wheels 2 are symmetrically and rotatably arranged on the surface of the hand plate 1. The gap between the two limiting wheels 2 is aligned with the guide groove 11. The magnetic strip sequentially passes between the two limiting wheels 2 and the guide groove 11 and is conducted to the winding station. The direct push assembly includes a second cylinder 6. The second cylinder 6 is installed on the surface of the base frame 61. The telescopic end of the second cylinder 6 is connected to the rear end of the hand plate 1. Two guide rods 62 are symmetrically and slidably penetrated through the surface of the base frame 61. The guide rods 62 are fixedly connected to the hand plate 1;

[0024] The driving assembly includes a first cylinder 3. The first cylinder 3 is installed on the surface of the hand plate 1. Two racks 4 are connected in a U-shaped distribution. The two racks 4 are slidably arranged on the surface of the hand plate 1. The telescopic end of the first cylinder 3 is connected to the two racks 4. A second gear 22 is coaxially and rotatably arranged below the limiting wheel 2 through a one-way bearing. The two racks 4 are respectively meshed and connected to the far sides of the two second gears 22;

[0025] The cutting assembly includes a blade 5. A sliding groove 52 is opened on one side of the guide groove 11. An L-shaped frame 51 is elastically slidably arranged in the sliding groove 52 through a spring. The blade 5 is connected to the top of the L-shaped frame 51. The bottom of the L-shaped frame 51 extends to one side of the hand plate 1. A second arc-shaped convex block 53 is fixed to the bottom end of the L-shaped frame 51. A first arc-shaped convex block 42 is fixed to the outer side of the rack 4;

[0026] Two first gears 21 are coaxially fixed to the two limiting wheels 2. A tooth block 41 is fixed to the end of the rack 4. The tooth block 41 is aligned with the first gear 21;

[0027] The magnetic strip passes through between two limiting wheels 2 and then through the guide groove 11 to the winding station. The two limiting wheels 2 clamp the magnetic strip. When winding the magnetic strip at the winding station, the two limiting wheels 2 rotate in opposite directions to conduct the magnetic strip. The second cylinder 6 is in a contracted state, causing the hand plate 1 to move away from the winding station. The first cylinder 3 contracts, causing the first arc-shaped convex block 42 to move away from the second arc-shaped convex block 53, and the tooth block 41 does not contact the first gear 21. When the winding of the magnetic strip is completed, the first cylinder 3 is activated to extend, driving the rack 4 to move forward in front of the hand plate 1. During this process, the rack 4 drives the second gear 22 to rotate, and the second gear 22 does not drive the limiting wheel 2 to rotate. When the rack 4 moves to the most forward position, the first arc-shaped convex block 42 abuts against the second arc-shaped convex block 53, causing the L-shaped frame 51 to slide against the elastic force, and the blade 5 cuts off the magnetic strip in the guide groove 11. The winding station can replace the winding disc and wait for the next winding;

[0028] When performing the next winding operation, the first cylinder 3 is activated to contract, causing the rack 4 to move backward behind the hand plate 1. The first arc-shaped convex block 42 disengages from the extrusion contact with the second arc-shaped convex block 53, and the elastic force causes the L-shaped frame 51 to reset. The blade 5 retracts into the sliding groove 52. During the backward movement of the rack 4, it will drive the second gear 22 to reverse, and the second gear 22 drives the limiting wheel 2 to rotate. The two limiting wheels 2 rotate in the reverse direction to convey the magnetic strip forward, causing the magnetic strip to pass through the guide groove 11 and extend a certain distance. When the rack 4 moves to the last position, the tooth block 41 engages with the first gear 21, fixing the limiting wheel 2 to ensure that the extended length of the magnetic strip will not retract. Then the second cylinder 6 is activated to extend, and under the guidance of the guide rod 62, the hand plate 1 moves closer to the winding station. The extended magnetic strip is fixed by the winding station. Then the first cylinder 3 is activated to extend a short distance, causing the rack 4 to move forward a short distance, releasing the engagement between the tooth block 41 and the first gear 21, and releasing the fixation of the limiting wheel 2. Then the second cylinder 6 is activated to contract to return the hand plate 1, completing the transmission of the magnetic strip.

[0029] An encoder 7 is installed at the bottom of the hand plate 1. The encoder 7 is connected to one of the limiting wheels 2. During the winding process of the magnetic strip, the magnetic strip will drive the hand plate 1 to rotate. The number of rotations of the hand plate 1 is monitored by the encoder 7 to calculate the winding length of the magnetic strip, facilitating the precise control of the single winding amount of the magnetic strip.

[0030] Auxiliary wheels 8 are symmetrically and rotatably installed at the rear of the surface of the hand plate 1. The magnetic strip passes through between the auxiliary wheels 8 and then through between the limiting wheels 2 to ensure the stable linear conduction of the magnetic strip.
