Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-2, a triple machine for medical suture needles, comprising: the machine frame 1, the machine frame 1 is equivalent to a workbench; a conveying mechanism 2 which is arranged on the frame 1 and horizontally conveys the straight needle 8; a presser plate 3 positioned above the conveying mechanism 2 for pressing the straight needle 8 onto the conveying mechanism 2; the driver 4 is in transmission connection with the conveying mechanism 2 to drive the conveying mechanism 2 to operate; the die 5 is provided with an imprinting lower die 51, a punching lower die 52 and a cutting lower die 53 which are sequentially and linearly arranged on the frame 1 along the conveying direction of the conveying mechanism 2, and an imprinting upper die 54, a punching upper die 55 and a cutting upper die 56 which are correspondingly and sequentially arranged above the die are connected with a pusher 9 for pushing downwards. A connecting arm 7 is mounted on one side of the frame 1, and an embossing upper die 54, a punching upper die 55, a cutting upper die 56, and a pusher 9 can be mounted on the connecting arm 7. The pusher 9 may be a pneumatic cylinder or a hydraulic cylinder pushing structure. Since the straight needle 8 is horizontally transferred by being placed on the transfer mechanism 2, the tops of the punch lower die 51, the punch lower die 52, and the cut lower die 53 are set to be not higher than the top of the transfer mechanism 2 in order to prevent the punch lower die 51, the punch lower die 52, and the cut lower die 53 from blocking the straight needle 8.

Specifically, the conveying mechanism 2 comprises two screws 21 which are arranged side by side in parallel and are positioned on two sides of the stamping lower die 51, the punching lower die 52 and the cutting lower die 53, two ends of each screw 21 are rotatably arranged on a fixed plate 22, the fixed plates 22 are arranged on the frame 1, one ends of the two screws 21, which are close to the stamping lower die 51, penetrate out of the fixed plates 22 and are in transmission connection with the driver 4, and the driver 4 drives the two screws 21 to rotate in the same direction so as to transmit the straight needle 8 from the stamping lower die 51 to the cutting lower die 53. Here, the straight needle 8 is placed in the thread groove of the two screws 21, and the straight needle 8 is placed vertically to the two screws 21, which rotates in synchronization with the two screws 21, and the straight needle 8 can be transferred. Since the straight needle 8 is cut and then divided into two to form two suture needles to be bent, the stamping and punching of the suture needles need to be ensured, and the cutting position is positioned at the center of the straight needle 8, the central lines of the stamping lower die 51, the punching lower die 52 and the cutting lower die 53 are further arranged at the centers of the two screw rods 21. The stable conveying of the straight needle 8 is achieved by whether the two screws 21 rotate synchronously in the same direction, and of course, the pitch of the two screws 21 is the same. The synchronous and co-rotation of the two screws 21 may be: the driver 4 comprises a motor 41, a first gear 42 is arranged at the output end of the motor 41, a second gear 43 is arranged at one end of the two screw rods 21 close to the motor 41, and the first gear 42 is positioned between the two second gears 43 and meshed with the two second gears 43. The transmission structure is simple and easy to install. The motor 41 drives the first gear 42 to rotate, drives the two second gears 43 to synchronously rotate in the same direction, and then synchronizes the two screws 21 to synchronously rotate in the same direction and reversely, so that the conveying mechanism 2 drives the straight needle 8 to move from left to right, and simultaneously the stamping lower die 51, the punching lower die 52 and the cutting lower die 53 are sequentially installed from left to right.

The two ends of the presser plate 3 are fixed on the fixed plates 22 at the two ends of the screw 21. Specifically, the presser plate 3 is located directly above the screw 21 and is parallel to the axial direction of the screw 21. Because the die 5 may adhere to the straight needle 8 during the pressing process, and then the straight needle 8 is carried up, only a gap not larger than the diameter of the cross section of the straight needle 8 is left between the bottom of the presser 3 and the threaded rod, so that the straight needle 8 is prevented from being shifted out of the threaded groove of the screw 21 during the conveying process. Here, the length of the presser plate 3 pressed against the screw 21 is shorter than the length of the screw 21, and both ends need to be left at the feeding and discharging positions. Of course, the two ends of the presser plate 3 may be fixed at other positions, for example, directly fixed to the frame 1 by a link structure, or the like.

Referring to fig. 2, considering the problem of the powder after the straight needle 8 is cut off, the screw thread of the separating rod 23 is not provided at the end of the two screw rods 21 far from the driver 4, and the reverse tooth 24 is installed on one screw rod 21 so that the powder rod on the two screw rods 21 rotates oppositely. The structure of the counter tooth 24 can refer to fig. 3, which is a prior art, and is not described herein in detail, and it uses three bevel gears to cooperate, so that the material distributing rod 23 sleeved on the screw 21 rotates in the opposite direction to the screw 21. The feed-separating rod 23 on the other screw 21 is integral with the screw 21, i.e. rotates in the same direction. Finally, the two cut-off needles are respectively driven to two sides by the two material separating rods 23.

Further, the stamping lower die 51 and the punching lower die 52 are connected by the bridge plate 6, and the tops of the bridge plate 6 and the stamping lower die 51, the punching lower die 52 and the cutting lower die 53 are in the same plane. The bridge plate 6 is a straight plate structure, which can strengthen the connection stability between the three lower dies, and can also support the middle part of the straight needle 8 in the intermittent area of the three lower dies. The bridge plate 6 is positioned on the center line of the imprint lower die 51, the punch lower die 52, and the cut-off lower die 53.

The structures of the stamping lower die 51, the punching lower die 52, the cutting lower die 53, and the corresponding stamping upper die 54, the punching upper die 55, and the cutting upper die 56 in the above process are conventional, and thus will not be described in detail.

The utility model uses the principle that:

Firstly, a plurality of straight needles 8 are sequentially placed in threaded grooves on two screws 21, the centers of the straight needles 8 are arranged on a bridge plate 6, the screws 21 rotate to sequentially pass the straight needles 8 through an embossing lower die 51, a punching lower die 52 and a cutting lower die 53, and the embossing, punching and cutting of the embossing upper die 54, the punching upper die 55 and the cutting upper die 56 are finished at one time. After cutting, the straight needles 8 enter the material distribution rods 23 from the screw rods 21, and the material distribution rods 23 on the two screw rods 21 rotate oppositely, so that the cut two straight needles 8 can be distributed to two sides.

The above description is only of the preferred embodiments of the present utility model; the scope of the utility model is not limited in this respect. Any person skilled in the art, within the technical scope of the present disclosure, may apply to the present utility model, and the technical solution and the improvement thereof are all covered by the protection scope of the present utility model.
