If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] Reference Figures 1 to 4The thread end cutting device of the first aspect embodiment of the present invention comprises a thread hooking assembly 100 and a scissors assembly 200. The thread hooking assembly 100 is used to hook the thread of the suture medicine package, and the scissors assembly 200 is used to cut the thread hooked by the thread hooking assembly 100, so that the length of the thread end left on the medicine package after suturing meets the production requirements of the medicine package. After the medicine bag is sewed, the sewing machine 400 will automatically cut the thread used to sew the medicine bag, and the length of the thread automatically cut by the sewing machine 400 is not long, which can meet the production requirements of the medicine bag, that is, after the medicine bag is sewed, the length of the thread remaining at the tail end of the sewed position of the medicine bag is usually able to meet the production requirements of the medicine bag; but currently the sewing machine 400 cannot control the length of the thread remaining at the head end of the sewed position after the medicine bag is sewed, so there will be a problem that some medicine bags do not meet the production requirements after sewed, and the medicine bags that do not meet the production requirements can only be discarded or require secondary processing, which will greatly increase the production cost; in addition, since the medicine bag is filled with flammable materials, each additional processing level will increase the processing risk. In order to solve the above-mentioned technical problems, and ensure that the length of the remaining thread at the beginning of the suture position after each suturing of the medicine package meets the production requirements of the medicine package, the present application proposes a thread cutting device, which can ensure that the remaining thread at the beginning of each suturing of the medicine package meets the production requirements of the medicine package by arranging the thread hook assembly 100 and the scissors assembly 200 on the periphery of the needle of the sewing machine 400. The thread cutting device and the medicine package suturing equipment of the present application are described in detail below in conjunction with the accompanying drawings.

[0036] In the embodiment of the present invention, the hooking assembly 100 includes a first telescopic structure 110, a hook piece 120 and a suction structure 130, wherein the hook piece 120 is installed at the movable end of the first telescopic structure 110, and the suction structure 130 is installed below the hook piece 120; the suction structure 130 is connected to a vacuum device, and the suction structure 130 is used to suck away the cut thread ends; the scissors assembly 200 includes a second telescopic structure 210 and a thread cutter 220, and the thread cutter 220 is installed at the movable end of the second telescopic structure 210. The first telescopic structure 110 is used to drive the hook piece 120 to move toward the direction close to the needle of the sewing machine 400, and the second telescopic structure 210 is used to drive the thread cutter 220 to move toward the direction close to the needle of the sewing machine 400; the first telescopic structure 110 and the second telescopic structure 210 can be telescopic cylinders, telescopic oil cylinders or electric telescopic devices, etc. The vacuum device can be purchased according to actual needs. The vacuum device of suitable power and size is not limited here. The thread cutting device of the embodiment of the present invention hooks the thread by the hook piece 120 of the thread hook assembly 100, and then uses the wire cutter 220 of the scissors assembly 200 to cut the thread between the hook piece 120 and the medicine package, which can ensure that after the medicine package is sewed, the length of the thread remaining at the beginning of the sew position of the medicine package meets the production requirements of the medicine package, thereby eliminating the need for secondary processing of the medicine package, greatly improving production efficiency, and reducing production costs and risks.

[0037] In the embodiments of the present invention, referring to Figure 1 As shown, the end of the hook piece 120 is arc-shaped; the hook piece 120 is provided with a hook groove 121, and the hook groove 121 is arranged on one side of the width direction of the hook piece 120. Specifically, the end of the hook piece 120 is arranged in an arc shape so that when the hook piece 120 moves toward the direction close to the wire, the wire can more easily enter the hook groove 121 along the arc-shaped end surface. The hook groove 121 is in a "7" shape, and the angle of the hook groove 121 is preferably an acute angle, so that the wire is not easy to escape from the hook groove 121 after the hook piece 120 hooks the wire.

[0038] In the embodiment of the present invention, the suction structure 130 is provided with a suction hole 131, the first end of the suction hole 131 is connected to the vacuum device, the second end of the suction hole 131 is arranged on the side of the suction structure 130 facing the hook piece 120; the second end of the suction hole 131 is arranged on the end of the suction structure 130 away from the first telescopic structure 110. For details, refer to Figure 2 As shown, the suction hole 131 is arranged inside the suction structure 130, and the aperture of the second end of the suction hole 131 is preferably smaller than the width of the hook piece 120, and the aperture of the first end of the suction hole 131 can be specifically set according to actual conditions. The second end of the suction hole 131 is arranged on the side facing the hook piece 120, which can ensure that after the line is hooked by the hook piece 120, the line can more easily enter the suction hole 131, and then after the line is cut, the line end can be sucked away by the suction hole 131. The second end of the suction hole 131 in the length direction is arranged to be closer to the hook groove 121 of the hook piece 120, so that the relative movement distance between the hook piece 120 and the suction structure 130 can be appropriately reduced, reducing the wear of both, and extending the service life of the device.

[0039] Furthermore, the suction structure 130 is wedge-shaped, and the end of the suction structure 130 is arc-shaped, so as to reduce interference with the wire and further increase the probability of the wire being sucked into the suction hole 131.

[0040] In the embodiment of the present invention, the hooking assembly 100 further includes a bracket 140 and a pressing piece 150. The fixed end of the first telescopic structure 110 and the pressing piece 150 are both mounted on the bracket 140. The hooking piece 120 is disposed between the pressing piece 150 and the suction structure 130. Figure 1As shown, the pressing sheet 150 is an elastic sheet. The purpose of setting the flattening is to tension the wire between the hook sheet 120 and the medicine package, so as to facilitate the scissors assembly 200 to cut the wire between the hook sheet 120 and the medicine package, and also ensure that the wire cutter 220 can cut the wire between the hook sheet 120 and the medicine package every time. When the hook sheet 120 hooks the wire into the hook groove 121, the movable end of the first telescopic structure 110 retracts to drive the hook sheet 120 to move away from the medicine package, and the wire hooked by the hook groove 121 of the hook sheet 120 will be compressed between the pressing sheet 150 and the hook sheet 120. Since the hook sheet 120 and the pressing sheet 150 need to slide relative to each other, and the pressing sheet 150 needs to apply pressure to the hook sheet 120 to tension the wire between the hook sheet 120 and the medicine package, the pressing sheet 150 needs to be elastic; preferably, the pressing sheet 150 is made of metal.

[0041] It can be imagined that the suction force applied by the suction structure 130 to the thread end needs to be greater than the force of the pressing sheet 150 clamping the thread end onto the hook piece 120. When the thread between the hook piece 120 and the medicine package is cut, in order to ensure that the thread clamped between the hook piece 120 and the pressing sheet 150 can be sucked away by the suction hole 131, it is necessary to ensure that the suction force applied by the suction hole 131 to the thread end is greater than the force of the pressing sheet 150 pressing the thread end onto the hook piece 120. The specific force is not limited in this embodiment and can be set according to actual conditions.

[0042] It should be understood that during each suturing process of the medicine bag, the suction hole 131 will inhale air twice. The first time is before the hook piece 120 moves, the vacuum device moves to generate suction in the suction hole 131, and the suction generated by the suction hole 131 will attract the thread on the needle of the sewing machine 400 to the hook piece 120, so that the hook piece 120 can easily and accurately hook the thread into the hook groove 121; the second time is before the scissors assembly 200 moves, the vacuum device moves to generate suction in the suction hole 131, so that after the thread cutter 220 cuts the thread between the hook piece 120 and the medicine bag, the suction hole 131 can suck the thread end into the suction hole 131. In summary, the suction hole 131 plays the role of guiding the thread and collecting thread end garbage during the entire operation.

[0043] Reference Figure 3 , Figure 4 As shown, the medicine bag suturing device according to the second embodiment of the present invention comprises a table 300, a sewing machine 400 and the thread cutting device, the thread cutting device and the sewing machine 400 are both mounted on the table 300, and the thread cutting device is mounted on the outer periphery of the needle of the sewing machine 400. Specifically, the table 300 is provided with a first adjustment structure 310 and a second adjustment structure 320, the thread hooking assembly 100 is connected to the first adjustment structure 310 by a fastener, and the scissors assembly 200 is connected to the second adjustment structure 320 by a fastener.

[0044] It should be noted that the position of the hook 120 should be carefully adjusted through the first adjustment structure 310 to ensure that the hook 120 can hook the thread every time when the hook 120 moves in the direction of the thread; similarly, the position of the scissor assembly 200 should be carefully adjusted through the second adjustment structure 320 to ensure that the thread cutter 220 can cut the thread between the hook 120 and the medicine bag every time when the thread cutter 220 moves in the direction of the thread. The medicine bag suturing device of the embodiment of the present invention can realize the automatic suturing of the filling port of the medicine bag, and the suturing medicine bag meets the production requirements without the need for secondary thread cutting; because the medicine bag suturing device includes the above-mentioned thread cutting device, it at least has all the beneficial effects of the thread cutting device.
