[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0025] like Figure 1-2As shown, the embodiment of the present invention discloses an ampoule bottle breaking device for a dispensing machine, comprising a bracket 1, a U-shaped top 2 for abutting against the head 21 and the bottle body 22 of the ampoule bottle 20, a top 3 for abutting against the neck 23 of the ampoule bottle 20, and a driving mechanism for driving the U-shaped top 2 and the top 3 to break the head 21 of the ampoule bottle 20 from both sides of the ampoule bottle 20 with the same pressure, the middle part of the U-shaped top 2 is a through groove, opposite to the scratch at the head 21, the upper end abuts against the head 21 (also called the nipple) of the ampoule bottle 20, and the lower end abuts against the bottle body 22. The driving mechanism, the U-shaped top 2 and the top 3 are all mounted on the bracket 1. Among them, the angle between the two side surfaces of the sharp corner of the top 3 is 60 degrees. The bracket 1 includes a bracket column 18, a bracket cross bar 19 and an L-shaped frame 24. The L-shaped frame 24 and the bracket column 18 are respectively installed on the lower sides of the two ends of the bracket cross bar 19. The U-shaped top 2 and the top 3 are installed on the bracket cross bar 19, so as to provide an operating space for clamping and breaking the lower ampoule bottle 20. The present invention can be adapted to a dispensing machine to achieve the breaking of the ampoule bottle 20. The U-shaped top 2 and the top 3 act on the ampoule bottle 20 at the same time and apply pressures of equal magnitude and opposite directions. Stress concentration will be formed at the scratch of the neck 23, and cracks will be generated. The cracks extend along the neck 23 of the ampoule bottle 20 until the head 21 and the bottle body 22 are separated. After the ampoule bottle 20 is broken, the bottle mouth is flat, and the bottle body 22 is not easy to break. It can adapt to different specifications of ampoule bottles 20 and is suitable for the ampoule bottle breaking device of the dispensing machine. Furthermore, the body 22 of the ampoule bottle 20 is clamped and fixed between the U-shaped top 2 and the top 3 by the air claws, and the heights of the necks 23 of the ampoules 20 of different specifications are the same, and the sharp corners of the necks 23 and the top 3 are on the same horizontal plane.

[0026] In this embodiment, in order to achieve the U-shaped top 2 and the top 3 to accurately lean against the ampoule bottle 20 from both sides, it also includes a guide rail 4, a U-shaped top slider 5, a top slider 6 and a hinge bracket 7 installed on the bracket 1. The U-shaped top slider 5 and the top slider 6 are slidably connected to the two ends of the guide rail 4 and can only move left and right. One end of the hinge bracket 7 is fixed to the U-shaped top slider 5, and the other end is hinged to the U-shaped top 2. The top 3 is fixed to the top slider 6. The driving mechanism drives the U-shaped top slider 5 and the top slider 6 to move relative to each other. The driving mechanism can adopt various forms to achieve the reciprocating motion of the U-shaped top slider 5 and the top slider 6. Among them, the hinge bracket 7, the top 3, the L-shaped frame 24 and the main body of the bracket column 18 are arranged in parallel.

[0027] In this embodiment, the driving mechanism includes a rotating member, a rope pulley 9, a driving rope 10, a reset assembly and a roller 11, wherein the driving rope 10 can adopt a variety of flexible material rope structures. In this embodiment, it is a flexible steel wire rope with less deformation. The rope pulley 9 is transmitted to a fixedly mounted rotating member. The rotating member adopts a driving motor 8 mounted on a support column 18 (the driving motor 8 is mounted on a motor mounting seat 16, and the motor mounting seat 16 is mounted on the support column 18). The rope pulley 9 is mounted on the output shaft of the driving motor 8. The roller 11 is mounted on the top slider 6. One end of the driving rope 10 is wound around the rope pulley 9, and the other end passes around the roller 11 and is fixedly connected to the U-shaped top slider 5. The roller 11 can change the direction of the driving rope 10, thereby, see Figure 1 The whole of the driving rope 10 is a U-shaped structure with an opening to the left, and the upper and lower ends of the driving rope 10 are arranged in parallel, and the U-shaped top slider 5 and the top slider 6 are reset by the reset assembly. Specifically, the reset assembly includes two reset springs 12 and four spring columns 13, and the ends of the four spring columns 13 are provided with holes for the reset springs 12 to hook out, wherein two spring columns 13 are respectively mounted on the bracket cross bar 19 (specifically, the L-shaped frame 24 on the lower side of the bracket cross bar 19) and the top 3 of the bracket 1, and the other two spring columns 13 are respectively mounted on the bracket column 18 of the bracket 1 and the hinge bracket 7, wherein the two ends of one reset spring 12 connect the bracket 1 and the spring column 13 on the top 3, and the two ends of the other reset spring 12 connect the bracket 1 and the spring column 13 on the hinge bracket 7.

[0028] In this embodiment, a force sensor fixing seat 14 is installed on the U-shaped top slider 5 by screws, and one end of the force sensor 15 is fixed to the force sensor fixing seat 14 by screws. The other end of the driving rope 10 is connected to the other end of the force sensor 15. In this application, the other end is indirectly fixed to the U-shaped top slider 5. Specifically, the force sensor 15 is a tension sensor. After the ampoule bottle 20 is broken, the force sensor 15 at the other end of the driving rope 10 detects a sharp drop in the tension of the driving rope 10, and sends a reverse signal to the driving motor 8. Under the tension of the reset springs 12 on both sides, the U-shaped top slider 5 and the top slider 6 move relative to each other and reset.

[0029] In this embodiment, the U-shaped top 2 is fixed on a hinge seat 17, and the hinge seat 17 is hinged to the other end of the hinge bracket 7, and the up and down swing angle of the hinge seat 17 is 45 degrees. Therefore, the U-shaped top 2 is connected to the hinge seat 17 in the form of a hinge, and the upper and lower ends of the U-shaped top 2 can be adaptively contacted with the ampoule bottle 20. When the height of the neck 23 of the ampoule bottle 20 is the same, the shape and size of the head 21 and the bottle body 22 of the ampoule bottle 20 of different specifications can be adapted. At the same time, the position distance deviation between the U-shaped top 2 and the top 3 of different ampoules 20 can be adapted.

[0030] The working process of the present invention is as follows:

[0031] In the initial stage, the U-shaped top slider 5 and the top slider 6 are at the two ends of the guide rail 4; after the driving motor 8 is started, the rotation of the motor shaft drives the rope wheel 9 to tighten the driving rope 10 to make the U-shaped top slider 5 and the top slider 6 approach each other. Then, if one of the tops 3 and U-shaped tops 2 installed in the two sliders contacts the ampoule bottle 20 first, it will stop and wait for the other part to contact the ampoule bottle 20; finally, the top 3 presses against the neck 23 of the ampoule bottle 20, the upper end of the U-shaped top 2 presses against the head 21 of the ampoule bottle 20, and the lower end of the U-shaped top 2 presses against the body 22 of the ampoule bottle 20, and the scratch on the neck 23 faces the U-shaped top 2. Driven by the driving motor 8, a driving rope 10 pulls the U-shaped top slider 5 and the top slider 6 to move, thereby driving the top 3 and the U-shaped top 2 to apply a breaking force to the ampoule bottle 20, so that the head 21 is disconnected from the body 22. After the ampoule bottle 20 is broken, the force sensor 15 detects a sharp drop in tension and sends a reverse signal to the drive motor 8. Under the tension of the return springs 12 on both sides, the U-shaped top slider 5 and the top slider 6 are reset.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
