Embodiment 1
[0016] as attached figure 1 As shown, the ampoule bottle opening device includes a box body 1, a bottleneck insertion hole 2 is arranged on the end panel of the box body, a motor 3 is fixed inside the box body, and the motor output shaft 3-1 is located on the same axis as the bottleneck insertion hole 2 superior.
[0017] as attached figure 1 As shown, the device also includes a U-shaped bracket 4, the horizontal rod 4-1 of the U-shaped bracket radially passes through the motor shaft and is fixed with the motor shaft, and a pair of rods 4-2 are respectively fixed at the bottom of the U-shaped bracket two sides. Circular cutting wheels 5, a bottleneck channel 6 is left between the two circular cutting wheels, and a motor start switch 7 is provided on the surface of the box body.
[0018] combined with figure 1 As can be seen from the above description, when working, the bottleneck of the ampoule is inserted into the bottleneck channel 6 between the two circular cutting wheel...
Embodiment 2
[0021] In this embodiment, the starting device of the motor is further improved, so that the bottleneck of the ampoule can automatically start the motor when it enters the box body.
[0022] as attached figure 2 As shown, in this embodiment, a self-starting device 9 is added in the bottle neck insertion hole 2, and the specific structure of the self-starting device 9 refers to the attached image 3 shown.
[0023] as attached image 3 As shown, the self-starting device 9 includes a cylindrical sleeve 11 that passes through the bottle neck insertion hole 2, and the two ends of the sleeve are provided with an outwardly expanded skirt 11-1, and the outer skirt of the sleeve and the end of the box body A support spring 12 is provided on the sleeve body between, and a micro switch 10 is provided on the box body wall at the edge of the bottle neck insertion hole.
[0024] After adopting the above structure, the sleeve 11 can move freely in the neck insertion hole 2. Since the ne...
Embodiment 3
[0026] From the description of Embodiment 1 and Embodiment 2, it can be seen that in order to make the device capable of scratching the neck of the ampoule, it is necessary to accurately control the distance between the outer edges of the two circular cutting wheels so that it can be just in line with the ampoule. The bottle neck is in contact with the outer wall. But in actual operation, the diameter of the bottle neck of the ampoule varies from large to small. If the distance between the outer edges of the two circular cutting wheels is fixedly set, it will inevitably cause limitations in the use of the device.
[0027] This embodiment is to provide a U-shaped support that can automatically adjust the distance between the two cutting wheels in response to the above problems. The structure of the U-shaped support is as follows: Figure 4 shown. The frame bar 4-2 on both sides of the U-shaped bracket is connected with the horizontal bar 4-1 by an elastic hinge device. Spring...
