DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] The following refers to the direction Figure 2The position of each component in the diagram is used as the reference.

[0033] like Figures 1 to 6 As shown, the medicine strip cutting device of the present invention comprises a frame 1, a cutter assembly 2, a power member 3 and a transmission mechanism 4, wherein the power member 3 and the transmission mechanism 4 are both arranged on the frame 1;

[0034] The cutter assembly 2 includes two cutting blades, which include a shearing main body 23. At least one of the front and rear ends of the shearing main body 23 is provided with a connecting portion 24. The left and right sides of the shearing main body 23 are respectively provided with cutting edges 25, and the cutting edges 25 are arranged along the length direction of the shearing main body 23. The two cutting blades are an upper cutting blade 21 and a lower cutting blade 22. The upper cutting blade 21 and the lower cutting blade 22 are respectively arranged on the transmission mechanism 4 through the connecting portion 24, and the upper cutting blade 21 and the lower cutting blade 22 are arranged parallel to each other up and down. The power member 3 can reciprocate the upper cutting blade 21 and the lower cutting blade 22 through the transmission mechanism 4. When the upper cutting blade 21 and the lower cutting blade 22 move closer, a shearing edge is formed between the two closest cutting edges 25 of the upper cutting blade 21 and the lower cutting blade 22.

[0035] The process flow of cutting medicine strips using the medicine strip cutting device is as follows: in the initial state, the upper cutting blade 21 and the lower cutting blade 22 overlap each other, and the power member 3 is first controlled to work so that the upper cutting blade 21 and the lower cutting blade 22 move apart, forming a shearing edge between the two closest blades 25; then the medicine strip is transported from top to bottom to the shearing edge, and the lower end of the medicine strip passes through the shearing edge and is held by the staff; finally, the power member 3 is controlled to work again, so that the upper cutting blade 21 and the lower cutting blade 22 move closer, and the blades of the upper cutting blade 21 and the lower cutting blade 22 contact the medicine strip, and the medicine strip is sheared and cut under the action of the blades of the upper cutting blade 21 and the lower cutting blade 22, thereby completing the cutting work of a section of the medicine strip.

[0036] Specifically, the function of the transmission mechanism 4 is to transmit power to the upper cutting blade 21 and the lower cutting blade 22, so that the upper cutting blade 21 and the lower cutting blade 22 can move back and forth to cut the medicine strip. In order to ensure the use effect of the transmission mechanism 4, a preferred structure of the transmission mechanism 4 of the utility model is: Figure 1 、 Figure 2As shown, the transmission mechanism 4 includes a synchronous pulley 41 and a synchronous belt 42. The synchronous pulleys 41 are rotatably provided on the left and right sides of the frame 1. The synchronous belt 42 is matched and fitted on the synchronous pulleys 41. The upper cutting blade 21 and the lower cutting blade 22 are both provided on the synchronous belt 42, and the upper cutting blade 21 and the lower cutting blade 22 are both perpendicular to the synchronous belt 42. With this transmission mechanism 4, the power element can be a motor. The rotation of the motor drives the synchronous pulley 41 to rotate. The rotation of the synchronous pulley 41 drives the synchronous belt 42 to reciprocate. The working principle is the same as that of a belt conveyor. The reciprocating movement of the synchronous belt 42 drives the reciprocating movement of the upper cutting blade 21 and the lower cutting blade 22.

[0037] Since the upper cutting blade 21 and the lower cutting blade 22 are made of steel, the synchronous belt 42 is also required to give the upper cutting blade 21 and the lower cutting blade 22 sufficient force when the medicine strip is cut. If a motor is used as a power part, the effect is not very good. In order to improve the shearing effect of the upper cutting blade 21 and the lower cutting blade 22, as shown in FIG. Figure 1 、 Figure 2 As shown, the synchronous belt 42 includes a left belt body 421, a right belt body 422, an upper slider seat 423 and a lower slider seat 424 which are enclosed and connected together in sequence. The left belt body 421 is mounted on the left synchronous pulley 41, and the right belt body 422 is mounted on the right synchronous pulley 41. The upper cutting blade 21 is vertically connected to the upper slider seat 423, and the upper cutting blade 21 is vertically connected to the lower slider seat 424. The power part 3 is a gas-liquid booster cylinder, and the piston rod of the gas-liquid booster cylinder is connected to the upper slider seat 423 or the lower slider seat 424 through the slider connecting block 43.

[0038] In order to facilitate the explanation of its working principle, the piston rod of the gas-liquid booster cylinder is described by taking the slider connecting block 43 and the upper slider seat 423 as an example. When the piston rod of the gas-liquid booster cylinder is extended (the piston rod moves to the left), it drives the slider connecting block 43 to move to the left, and the slider connecting block 43 drives the upper slider seat 423 to move to the left. The upper slider seat 423 moves to the left and drives the upper cutting blade 21 to move to the left. At the same time, the entire synchronous belt 42 rotates counterclockwise around the synchronous pulley 41, causing the lower slider seat 424 to move to the right at the same time. The lower slider seat 424 moves to the right and drives the lower cutting blade 22 to move to the right, that is, the upper cutting blade 21 and the lower cutting blade 22 move apart, forming a shearing edge between the two closest blades 25. When the medicine strip is transported from top to bottom to the shearing edge, the medicine strip is After the lower end of the strip passes through the shearing edge and is held by the staff, the piston rod of the gas-liquid booster cylinder retracts (the piston rod moves to the right), driving the slider connecting block 43 to move to the right, and the slider connecting block 43 drives the upper slider seat 423 to move to the right, and the upper slider seat 423 moves to the right, driving the upper cutting blade 21 to move to the right. At the same time, the entire synchronous belt 42 rotates clockwise around the synchronous pulley 41, causing the lower slider seat 424 to move to the left at the same time, and the lower slider seat 424 moves to the left, driving the lower cutting blade 22 to move to the left, causing the upper cutting blade 21 and the lower cutting blade 22 to move closer, and the blades of the upper cutting blade 21 and the lower cutting blade 22 contact the medicine strip, and under the action of the blades 25 of the upper cutting blade 21 and the lower cutting blade 22, the medicine strip is sheared and cut, thereby completing the cutting work of a section of medicine strip. Since the left and right sides of the cutting blade are respectively provided with blades 25, the piston rod of the gas-liquid booster cylinder continues to retract (the piston rod moves to the right), driving the slider connecting block 43 to move to the right, and the slider connecting block 43 drives the upper slider seat 423 to move to the right, and the upper slider seat 423 moves to the right, driving the upper cutting blade 21 to move to the right. At the same time, the entire synchronous belt 42 rotates clockwise around the synchronous pulley 41, causing the lower slider seat 424 to move to the left at the same time, and the lower slider seat 424 moves to the left, driving the lower cutting blade 22 to move to the left, that is, the upper cutting blade 21 and the lower cutting blade 22 move apart, forming a shearing edge between the two closest blades 25. After the medicine strip is transported from top to bottom to the shearing edge, and the lower end of the medicine strip passes through the shearing edge and is held by the staff, the gas-liquid booster cylinder is The piston rod extends (the piston rod moves to the left), driving the slider connecting block 43 to move to the left, and the slider connecting block 43 drives the upper slider seat 423 to move to the left. The upper slider seat 423 moves to the left, driving the upper cutting blade 21 to move to the left. At the same time, the entire synchronous belt 42 rotates counterclockwise around the synchronous pulley 41, causing the lower slider seat 424 to move to the right at the same time. The lower slider seat 424 moves to the right, driving the lower cutting blade 22 to move to the right, causing the upper cutting blade 21 and the lower cutting blade 22 to move closer, and the blades of the upper cutting blade 21 and the lower cutting blade 22 contact the medicine strip. Under the action of the blades 25 of the upper cutting blade 21 and the lower cutting blade 22, the medicine strip is sheared and cut, thereby completing the cutting work of the next section of the medicine strip. At this time, the upper cutting blade 21 and the lower cutting blade 22 overlap up and down and return to the initial state.This arrangement enables the gas-liquid booster cylinder to drive the upper cutting blade 21 and the lower cutting blade 22 to move back and forth once to complete the cutting work of two sections of the medicine strip, further improving the efficiency of the medicine strip cutting, and also facilitating the operation of the gas-liquid booster cylinder and facilitating automatic control.

[0039] The gas-liquid booster cylinder can be an air cylinder or an oil cylinder, preferably an air cylinder.

[0040] In order to facilitate the connection between the upper slider seat 423, the lower slider seat 424 and the left belt body 421 and the right belt body 422, Figure 1 As shown, the left and right sides of the upper slider seat 423 are connected to the left belt body 421 and the right belt body 422 respectively through the first U-shaped connecting block 425, and the left and right sides of the lower slider seat 424 are connected to the left belt body 421 and the right belt body 422 respectively through the second U-shaped connecting block 426.

[0041] In order to reduce the possibility of deviation of the upper slider seat 423 and the lower slider seat 424 during reciprocating movement, left and right slide rails are provided on the frame 1, and the upper slider seat 423 and the lower slider seat 424 are respectively provided on one slide rail.

[0042] In order to further improve the stability of the entire device and ensure the effect of use, Figure 1 、 Figure 2 As shown, there are two transmission mechanisms 4, which are arranged parallel to each other on the front and rear sides of the frame 1. The front and rear ends of the shearing body 23 are respectively provided with connecting portions 24. The front and rear ends of the upper cutting blade 21 are respectively connected to the upper slider seats 423 of the two transmission mechanisms 4, and the front and rear ends of the lower cutting blade 22 are respectively connected to the lower slider seats 424 of the two transmission mechanisms 4. The synchronous pulleys 41 of the two transmission mechanisms 4 are connected together by two synchronous rotating shafts 7. Driven by the synchronous rotating shafts 7, the two transmission mechanisms 4 operate synchronously, thereby effectively improving the stability of the entire device and the shearing effect of the cutter assembly 2.

[0043] In order to protect the cutter assembly and ensure that the cutter assembly moves back and forth within a limited position range, buffer limiters 5 are respectively provided on the left and right sides of the frame 1. The front section of the buffer limiter 5 is composed of a spring and the rear section is composed of a thread. By adjusting the position of the nut, buffering of different distances can be achieved.

[0044] Because the medication strip is cylindrical and is fed from top to bottom to the shearing edge, to facilitate the lower end of the medication strip's passage through the shearing edge and improve the performance of the cutter assembly, the width of the upper surface of the shearing body 23 of the upper cutting blade 21 is smaller than the width of its lower surface, and the blade 25 of the upper cutting blade 21 is positioned at the edge of the lower surface of the shearing body 23. The width of the upper surface of the shearing body 23 of the lower cutting blade 22 is larger than the width of its lower surface, and the blade 25 of the lower cutting blade 22 is positioned at the edge of the upper surface of the shearing body 23. Both the upper and lower surfaces of the shearing body 23 are rectangular. Further improving the performance of the cutter assembly include: the blade 25 is an inwardly concave arc shape, the blade shape is axially symmetrical, and the hardness of the blade 25 is HRC57-63.

[0045] The cutting blades are usually connected and fixed by bolts. In order to prevent the bolts from affecting the use of the upper cutting blade 21 and the lower cutting blade 22, a countersunk hole 26 for connection is provided on the connecting portion 24.

[0046] In summary, compared with the prior art of manually cutting off medicine strips, the manual labor intensity is significantly reduced, the requirements for personnel are lowered, the cutting efficiency is improved, and it is conducive to automated production.
