In the initial state: the second spring 34 is in compression with the first spring 28.
When the work is started:
1. the needle head placing cavity 54 is internally provided with a needle head, the needle tube placing cavity 11 is internally provided with a needle tube, the needle head in the needle head placing cavity 54 can drop to the needle head cavity 53, the needle tube in the needle tube placing cavity 11 can drop to the needle tube cavity 31, the motor 58 is started when machining is started, the motor 58 drives the first shaft 59 to rotate, the first shaft 59 rotates to drive the second gear 60 and the right semicircular gear 61 to rotate, the second gear 60 rotates to drive the third gear 65 to rotate, the third gear 65 rotates to drive the second shaft 64 to rotate, the second shaft 64 rotates to drive the left semicircular gear 63 to rotate, the left semicircular gear 63 and the right semicircular gear 61 rotate to drive the fourth gear 55 to rotate left and right in a reciprocating manner, and the fourth gear 55 rotates left and right in a reciprocating manner to drive the third shaft 56 to rotate left and right in a reciprocating manner, the third shaft 56 reciprocates left and right to rotate the first gear 48 and the fifth belt pulley 46, the first gear 48 reciprocates left and right to rotate the left rack 50 first to move right, and the left rack 50 moves right to move the left slider block 52 to move right.
2. At the same time, the fifth belt pulley 46 rotates to drive the sixth belt pulley 41 through the belt 45, the sixth belt pulley 41 rotates to drive the fourth shaft 39 to rotate, the fourth shaft 39 rotates to drive the seventh gear 40 to rotate, the seventh gear 40 rotates to drive the eighth gear 38 to rotate, the eighth gear 38 rotates to drive the fifth shaft 36 to rotate, the fifth shaft 36 rotates to drive the ninth gear 37 to rotate, and the ninth gear 37 rotates to drive the right rack 42 to move leftward first.
3. When the right sliding block 43 contacts with the left sliding block 52, the needle head is pressed to move leftwards to the needle head blocking cavity 67 to be blocked by the needle head blocking cavity 67 and then inserted into the needle tube at the right side, meanwhile, when the needle head is inserted into the needle tube, the position above the needle tube, which is limited by the box body, can not be bounced upwards, so that the needle head can be correctly inserted into the needle tube, when the needle head is inserted into the needle tube, then the left slider 52 and the right slider 43 move to the extreme positions and start to return, when the left slider 52 starts moving to the left, the right slider 43 moves to the right, and the left slider 52 moves to the left, the needle within needle placement cavity 54 cannot fall out because it is blocked by needle stop 66, when the needle chamber 53 moves below the needle placement chamber 54, the needle will fall into the needle chamber 53.
4. Due to the difference of the transmission ratio, the right sliding block 43 moves for a longer distance than the left sliding block 52, when the right sliding block 43 moves rightwards to the needle tube placing cavity 11, the fixed block 44 is blocked by the rotating block 15, the rotating block 15 is subjected to excessive pressure due to the fact that the right sliding block 43 cannot move rightwards, the fixed block 44 is caused to pass through by the torsion spring 14 rotating rightwards, when the right sliding block 43 continues to move rightwards to the upper part of the triangular fixed block 25, the triangular fixed block 25 pushes the moving block 32 to move upwards, the moving block 32 moves upwards, the processed syringe is pushed to move upwards to leave the needle tube cavity 31, then the syringe slides to the storage box 26 through the inclined plane on the right sliding block 43 at the rear side to be stored, when the syringe leaves the needle tube cavity 31, the pressure block 33 is subjected to the resilience force of the second spring 34 to move upwards to the needle tube cavity 31, the pressure block 33 moves upward to drive the sliding connecting rod 69 to move upward, the sliding connecting rod 69 moves upward to release the rope 72, and the limit block 29 is subjected to the resilience of the first spring 28 to move rightward.
5. Then the right sliding block 43 moves to the extreme position to start moving to the left, when the right sliding block 43 moves to the right of the rotating block 15 to the left, the fixed block 44 will push the rotating block 15 to move to the left, the rotating block 15 moves to the left to drive the closing block 24 to move to the left and drive the flexible closing block 13 to move to the left to enter the spring chamber 10 to compress the third spring 12, the needle tube placing chamber 11 is not blocked by the flexible closing block 13 below, when the hollow chamber 16 moves to the below of the needle tube placing chamber 11, the needle tube placing chamber 11 is in communication with the needle tube chamber 31, so that the needle tube in the needle tube placing chamber 11 falls into the needle tube chamber 31, and when the closing block 24 moves to the left to drive the triangular sliding block 19 to move to the left through the connecting rod 23 and stretch the fourth spring 20, the leftward movement of the triangular slider block 19 inserts the lowermost needle tube and the upper needle tube, and closes the remaining needle tubes except the lowermost needle tube in the needle tube placing chamber 11.
6. When the lowest needle tube in the needle tube placing cavity 11 falls into the needle tube cavity 31, gravity presses the pressure block 33 to move downwards and compress the second spring 34, the downward movement of the pressure block 33 drives the sliding connecting rod 69 to move downwards so as to pull the rope 72, the stopper 29 is pulled by the rope 72 to move leftwards and stretch the first spring 28, the stopper 29 abuts against the right end surface of the needle tube, then the right sliding block 43 continues to move leftwards, when the fixed block 44 pushes the rotating block 15 to push leftwards until the rotating block rotates leftwards and upwards to the lower part of the spring cavity 10 so as to pass the fixed block 44, when the fixed block 44 passes through, the flexible closing block 13 is pushed by the resilience force of the third spring 12 so as to drive the closing block 24 to move rightwards so that the flexible closing block 13 seals the downward opening of the needle tube placing cavity 11 again, the closure block 24 moves to the right and simultaneously the triangular slide block 19 moves to the right and the needle inside the needle placing chamber 11 can move downward.
7. The next processing of the needle tube and needle is then carried out until the processing is completed, the motor 58 is switched off, the processed syringe in the storage box 26 is then removed, and the device is reset.
The above description is only an embodiment of the invention, but the scope of the invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the invention. Therefore, the protection scope of the invention should be subject to the protection scope defined by the claims.
