[0025] like Figure 1-4 As shown, an ampoule opening device includes a housing 1. A cutting mechanism, a cap recycling mechanism, and a driving mechanism are arranged inside the housing 1. The cutting mechanism includes several blade holders 2 rotatably connected to the housing 1 and cutting blades 3 fixed on the blade holders 2. The cap recycling mechanism includes a recycling trough, several positioning seats, and cap pressing seats 17 hinged to each mounting seat 16. Ampoule positioning holes 18 are provided at the bottom of the positioning seats. The housing 1 has mounting through holes corresponding to the positioning seats. The base is fixedly connected to the housing 1, and the ampoule positioning hole 18 corresponds to the mounting through hole. The cap pressing base 17 is provided with a pressing groove 19 corresponding to the ampoule positioning hole 18, and the bottom of the pressing groove 19 is provided with a cap through hole. The cutting blade 3, the cap through hole, and the ampoule positioning hole 18 correspond one-to-one, and the cutting blade 3 is located between the cap through hole and the ampoule positioning hole 18. The drive mechanism drives the cutting blade 3 and the cap pressing base 17 to swing, and the swing direction of the cutting blade 3 and the cap pressing base 17 is perpendicular. Specifically, the recycling tank can be a tank with an open top, located at the bottom of the housing, to facilitate the entry of broken caps into the recycling tank.

[0026] During use, the staff inserts the ampoule cap into the equipment through the positioning hole, through the cap through hole, and then the drive mechanism starts. The cutting blade swings to cut, and the cap pressing seat swings to break the cap. The broken cap enters the recycling tank, completing the opening operation on one side.

[0027] In one embodiment, the mounting base 16 includes a fixed base plate with two hinged support plates. The bottle cap pressing seat 17 is located between the two hinged support plates and is rotatably connected to the hinged support plates via a hinge shaft. Under the drive of the driving mechanism, the bottle cap pressing seat swings and breaks the bottle cap. After breaking, the bottle cap is recycled.

[0028] In one embodiment, the drive mechanism includes a drive motor 4, a drive gear 5 that is driven and connected to the output end of the drive motor 4, and a driven gear 6 that meshes with the drive gear 5; the drive gear 5 is driven and connected to the bottle cap pressure seat 17 through a first transmission mechanism, and the driven gear 6 is driven and connected to the knife holder 2 through a second transmission mechanism, so that the drive mechanism drives the knife holder to swing.

[0029] In one embodiment, the first transmission mechanism includes a transmission pressure plate 7 connected to the bottle cap pressure seat 17 and a first transmission connecting rod 8 connected to the drive gear 5. One end of the first transmission connecting rod 8 is eccentrically connected to the drive gear 5, and the other end of the first transmission connecting rod 8 is connected to the transmission pressure plate 7. Specifically, the transmission pressure plates and the bottle cap pressure seats can be connected one-to-one, and each transmission pressure plate is connected by a connecting rod. The connecting rod and the first transmission connecting rod are fixedly connected by a connecting plate.

[0030] In one embodiment, the second transmission mechanism includes a cutting tool linkage group 9 connecting each cutting tool holder 2, a transmission pull rope 10 connecting the cutting tool linkage group 9, a second transmission link 11 connecting the driven gear 6, a guide rail 12 disposed below the driven gear 6, and a sliding seat 13 that slides with the guide rail 12. One end of the transmission pull rope 10 is connected to the first transmission link 8, and the other end of the transmission pull rope 10 is connected to the sliding seat 13. The drive motor drives the gear to rotate back and forth, and then the second transmission link 11 drives the sliding seat 13 to reciprocate along the guide rail 12.

[0031] In one embodiment, the sliding seat 13 includes a base that slides with the guide rail 12. A push rod 14 is hinged to the upper side of the base, and the push rod 14 is engaged with the second transmission link 11 for transmission. In its natural state (without external force), the push rod 14 is inclined, with one end face of the push rod 14 abutting against the upper side of the base, and the other end face of the push rod 14 perpendicular to the upper side of the base. Specifically, this state can be maintained by providing a torsion spring on the hinge shaft, or by installing the hinge shaft closer to one end of the push rod 14, so as to maintain the inclined state naturally under the action of gravity.

[0032] During operation, the motor drives the drive gear 5, which in turn drives the driven gear 6 to rotate. The second transmission link 11 swings, causing the sliding seat 13 to move. Specifically, as shown in the attached diagram, the second transmission link 11 abuts against one end of the push rod 14. When the second transmission link 11 swings clockwise, the push rod 14 moves the sliding seat 13. When the second transmission link 11 separates from the push rod 14, the sliding seat 13 stops moving. When the second transmission link 11 is located above the push rod 14, the second transmission link 11 swings counterclockwise, abutting against the upper side of the push rod 14 and moving the sliding seat 13. When the second transmission link 11 separates from the push rod 14, the sliding seat 13 stops moving. When the second transmission link 11 approaches the end of the push rod 14, the motor rotates in both directions, causing the sliding seat 13 to reciprocate along the guide rail 12.

[0033] In one embodiment, an arc-shaped baffle 20 is provided on the lower side of the ampoule positioning hole 18 corresponding to the body of the ampoule, so that the staff can place the body of the ampoule against the inside of the arc-shaped baffle to avoid displacement.

[0034] In one embodiment, the mounting bases 16 are arranged in a straight line, and the inner diameters of the ampoule positioning holes 18 are arranged in ascending order. The cap through hole corresponds to the position and specifications of the ampoule positioning hole 18, and the staff can select the ampoule positioning hole according to the ampoule specifications.

[0035] In one embodiment, the housing 1 includes a rectangular shell and an inverted V-shaped top cover (not shown in the figure). The top surface of the rectangular shell is open and a support plate 15 is provided on the front side. The support plate 15 is inclined towards the outside of the housing 1 for easy assembly. A mounting through hole is provided on the support plate 15, and the blade holder 2 is rotatably connected to the support plate 15. An exhaust fan is installed on the side of the housing. During use, the exhaust fan draws air out of the housing, creating a negative pressure environment inside the housing. This facilitates the entry of cutting debris into the recycling tank inside the housing, reducing the amount of glass fan debris falling into the bottle.

[0036] In one embodiment, a partition is provided inside the housing 1, with the drive motor 4 located on one side of the partition and the driving gear 5 and driven gear 6 located on the other side of the partition for easy assembly; the housing 1 is provided with several guide wheels 21, and the pull rope is wound around each guide wheel 21 to avoid the pull rope becoming messy.

[0037] It should be noted that, for ease of use, the device is also equipped with common electrical control systems such as sensors and controllers, so that when the operator inserts the ampoule into the ampoule positioning hole to open it, the controller can promptly control the drive mechanism to start the opening operation. This electrical control system can adopt existing technology and is not the key improvement of this utility model, so it will not be described in detail.

[0038] The above embodiments can be combined with each other.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
