[0043] The complete working principle and steps of the above embodiment are as follows:
[0044] refer to Figures 1 to 5 As shown, when the device is in the initial state, the upper die 11 and the lower die 12 are in an expanded state, the right end of the rack 13 is engaged with the outer surface of the gear 17, the first spring 112 is in a naturally relaxed state, and the electric push rod 16 is in a contracted state;
[0045] When the device is used for processing, the upper mold 11 and the lower mold 12 are first installed inside the left side of the production equipment 1. At this time, the left side of the production equipment 1 will drive the upper mold 11 to move to the right. When the upper mold 11 moves to the right, it will drive the first fixed rod 14 to move at the same time. When the first fixed rod 14 moves to the right, it will drive the rack 13 to move at the same time. Since the bottom of the right side of the rack 13 is engaged with the outer surface of the gear 17, as the rack 13 slides to the right, it will drive the gear 17 to rotate. When the gear 17 rotates, it will drive the screw rod 18 to slide backward. When the screw rod 18 slides, it will drive the telescopic parts 110 and the second fixed plate 111 at both ends to slide at the same time. Since the upper clamping plate 19 is clamped on the inner side of the square groove of the second fixed plate 111, and the telescopic part 1 The rear side of 10 is fixedly connected to the front end of the upper clamping plate 19. At this time, the telescopic member 110 and the second fixed plate 111 will drive the upper clamping plate 19 to slide backward, and the second fixed plate 111 will also drive the lower clamping plate 113 to slide backward at the same time. As the upper mold 11 moves to the right and fits with the lower mold 12, it will not be blocked by the upper clamping plate 19 and the lower clamping plate 113. When the upper mold 11 moves to the left, the syringe 101 can be pushed out, and the right side of the syringe 101 is detachably connected to the left side of the lower mold 12. As the upper mold 11 slides to the left, the rack 13 will be driven to move at the same time through the first fixed rod 14. When the rack 13 moves to the left, it will drive the gear 17 to rotate in the opposite direction. When the gear 17 rotates in the opposite direction, the telescopic member will be driven through the screw rod 18. When the upper clamping plate 19 is moved forward, the upper clamping plate 19 is pressed against the inner surface of the first clamping plate 15, and the lower clamping plate 113 is pressed against the inner surface of the first clamping plate 15. When the upper clamping plate 19 is moved forward, the upper clamping plate 19 is pressed against the inner surface of the first clamping plate 15, and the lower clamping plate 113 is pressed against the inner surface of the first clamping plate 15. When the upper clamping plate 19 is pressed downward, the upper clamping plate 19 is stretched at the same time, and the first spring 112 is compressed. When the upper clamping plate 19 moves downward, the lower surface of the upper clamping plate 19 will be pressed and fitted to the upper surface of the syringe 101. At this time, the output end of the electric push rod 16 will drive the first fixed plate 15 to move to the left. When the first fixed plate 15 moves to the left, it will drive the upper clamping plate 19 and the lower clamping plate 113 to move to the left at the same time. The upper clamping plate 19 and the lower clamping plate 113 can clamp the outer surface of the syringe 101 and move to the left at the same time, so that the right side of the syringe 101 is separated from the fit with the left side of the lower mold 12, so that multiple syringes 101 can be taken out at one time, reducing the number of times to take out parts, shortening the entire production cycle, and compared with a robot arm that needs multiple operations, this mechanism reduces the frequency and complexity of using the robot arm, and also reduces the operating complexity of the equipment.
[0046] As the upper mold 11 drives the rack 13 to move to the right through the first fixed rod 14, the gear 17 will drive the screw rod 18 to move backward at the same time, and the screw rod 18 will drive the upper clamping plate 19 to move backward through the telescopic member 110 and the second fixed plate 111. At this time, the inclined surface of the upper clamping plate 19 will be out of contact with the arc surface of the first fixed plate 15. At this time, the first spring 112 in a compressed state will drive the upper clamping plate 19 to move upward, and when the upper clamping plate 19 moves upward, it will also drive the telescopic member 110 to contract at the same time.
[0047] refer to Figures 6 to 8 As shown, when the device is in the initial state, the collecting frame 2 is located between the upper mold 11 and the lower mold 12;
[0048] As the upper mold 11 moves to the right, the rotating member 23 is driven to move at the same time. When the rotating member 23 moves to the right, the guide cylinder 24 is caused to rotate outward. When the guide cylinder 24 rotates, the rotating shaft 21 is driven to rotate at the same time, causing the rotating shaft 21 to rotate on the inner side of the production equipment 1. Since the outer surface of the rotating shaft 21 is symmetrically fixedly connected to the front end of the connecting rod 22, when the rotating shaft 21 rotates outward, the connecting rod 22 is driven to rotate at the same time. When the connecting rod 22 rotates outward, the collecting frame 2 on the inner side of the connecting rod 22 is driven to rotate at the same time. At this time, when the upper mold 11 moves to the right to fit the lower mold 12 to produce the syringe 101, it will not be blocked by the collecting frame 2. As the upper mold 11 moves to the left, it will drive The rotating part 23 moves at the same time. When the rotating part 23 moves to the left, it will drive the guide cylinder 24 to rotate inward. As the guide cylinder 24 rotates inward, it will drive the connecting rod 22 to rotate at the same time through the rotating shaft 21, and the connecting rod 22 will drive the collecting frame 2 to flip inward, prompting the collecting frame 2 to return to between the upper mold 11 and the lower mold 12. At this time, when the syringe 101 falls off from the left side of the lower mold 12, it will fall into the inner side of the collecting frame 2, reducing the steps of manual collection and transportation, and when the upper mold 11 moves to the right, it can drive the collecting frame 2 to flip upward, so that the collecting frame 2 will not occupy the working space of the upper mold 11, ensuring the continuity and stability of the upper mold 11 during the production process.
[0049] refer to Figures 9 to 12 As shown, when the device is in the initial state, the first limiting rod 3 has not yet been attached to the limiting member 31, the bottom of the front end of the limiting member 31 is clamped on the upper surface of the sliding bar of the lower clamping plate 113, the torsion spring 32 is in a naturally relaxed state, and the second spring 33 is in a stretched state;
[0050] As the output end of the electric push rod 16 is pushed outward, the electric push rod 16 drives the first fixing plate 15 to slide to the left on the outer surface of the fixing frame 114. At this time, the first fixing plate 15 drives the lower clamping plate 113 to slide at the same time. When the lower clamping plate 113 slides to the left, it drives the limiting member 31 to slide at the same time. As the limiting member 31 slides to the left, the lower surface of the limiting member 31 will fit the inclined surface of the first limiting rod 3. At this time, when the limiting member 31 continues to slide to the left, the inclined surface of the first limiting rod 3 will cause the limiting member 31 to flip upward When the limiting member 31 flips upward, it will drive the torsion spring 32 to rotate to the power storage state, and the bottom of the limiting member 31 will be disengaged from the upper surface of the sliding bar of the lower clamping plate 113. At this time, the second spring 33 in the stretched state will drive the sliding bar of the lower clamping plate 113 to slide to the inner side of the fixed sleeve of the lower clamping plate 113. As the sliding bar of the lower clamping plate 113 slides inward, it will be disengaged from the bottom of the syringe 101, thereby prompting the syringe 101 to fall into the inner side of the collection frame 2, thereby realizing the automatic collection of the syringe 101.
[0051] As the output end of the electric push rod 16 contracts inwardly, the electric push rod 16 will drive the first fixing plate 15 to slide rightward on the outer surface of the fixing frame 114. At this time, the first fixing plate 15 will drive the lower clamping plate 113 to move at the same time, and the movement of the lower clamping plate 113 will drive the limiting member 31 to move at the same time, causing the lower surface of the limiting member 31 to be out of contact with the inclined surface of the first limiting rod 3, and the lower surface of the limiting member 31 will be in contact with the upper surface of the sliding strip of the lower clamping plate 113. As the second fixing plate 111 drives the lower clamping plate 113 to slide backward on the inner side of the first fixing plate 15, the lower clamping plate 113 will be out of contact with the inclined surface of the first limiting rod 3. The front end of the sliding strip of plate 113 will be blocked by the inner side of the first fixed plate 15, and as the lower clamp plate 113 continues to slide backward, the fixed sleeve of the lower clamp plate 113 will slide out from the outer surface of the sliding strip of the lower clamp plate 113, and the fixed sleeve of the lower clamp plate 113 will drive the second spring 33 to return to the extension when sliding backward. When the fixed sleeve of the lower clamp plate 113 slides to the rearmost end of the moving strip of the lower clamp plate 113, the torsion spring 32 in the force storage state will drive the limiting member 31 to flip downward, causing the lower surface of the limiting member 31 to be re-engaged with the upper surface of the sliding strip of the lower clamp plate 113 to return to the initial state.
[0052] refer to Fig.13 and Fig.14As shown, when the upper mold 11 slides to the right, it will drive the limit frame 41 to slide at the same time. Since the inner side of the limit frame 41 is in a squeeze fit with the outer surface of the moving part 43, as the limit frame 41 slides to the right, the moving part 43 will be prompted to slide upward, and when the moving part 43 slides upward, it will drive the second limit rod 42 to slide upward on the inner side of the second fixed rod 4 at the same time. At this time, the upper mold 11 and the lower mold 12 will not be blocked by the second limit rod 42 when squeezing the syringe 101 to produce the syringe 101. As the upper mold 11 drives the limit frame 41 to slide to the right, the limit frame 41 will drive the moving part 43 to slide downward, and when the moving part 43 slides downward, it will drive the second limit rod 42 to slide on the inner side of the second fixed rod 4 at the same time. At this time, when the syringe 101 detaches from the right side of the lower mold 12, the outer surface of the second limit rod 42 can block the syringe 101, which can effectively prevent the syringe 101 from shifting in position during the falling process, so that the syringe 101 can accurately fall into the collection frame 2.
