It will not be too tight so that the material cannot enter, nor will it be too loose so that the bottle body 1 in the material can be dumped into the inner cavity of the demolding frame 17-2. In the present invention, materials of different specifications and sizes correspond to different demolding frames 17-2, and the demolding frame 17-2 is adjusted according to the size specifications of the material before each processing.

[0027] A bottle inlet 17-202 is arranged on a side of the film stripping frame 17-2 adjacent to the double-sided film cutting channel 5-2. The height of the bottle inlet 17-202 is consistent with the height of the bottle body 1, and the width is matched with the overall width of the bottle body 1 placed side by side. A lifting plate 17-3 matched with the cross-section of its inner cavity is arranged at the bottom of the film stripping frame 17-2. The default position of the lifting plate 17-3 is flush with the height of the double-sided film cutting channel 5-2, ensuring that the material entering from the bottle inlet 17-202 can be smoothly pushed to the lifting plate 17-3, and the problem of material pushing failure will not occur. The lifting plate 17-3 is driven by the lifting plate lifting structure 17-4, and moves up and down along the inner cavity of the film stripping frame 17-2. In this embodiment, the lifting plate lifting structure drive 17-4 is realized based on a linear servo electric cylinder, and the lifting plate 17-3 is fixedly connected to the slide seat of the servo electric cylinder. The lifting plate 17-3 is arranged inside the film stripping frame 17-2. When the material is pushed onto the lifting plate 17-3, the side wall of the film stripping frame 17-2 opposite to the bottle inlet 17-202 plays a limiting role, ensuring that the material can be completely pushed onto the lifting plate 17-3 and will not be pushed out of the lifting plate 17-3 from the other side.

In the present invention, materials of different specifications and sizes correspond to different film stripping frames 17 - 2 and lifting plates 17 - 3 , ensuring that the present invention is applicable to the stripping operation of bottles 1 and diaphragms 2 of different specifications and sizes.

After the demolding tooth replacement cylinder 17-6 is started, the piston rod pulls the replacement plate 17-101 to slide horizontally on the demolding tooth replacement slide rail 17-5, and the demolding tooth 17-1 slides horizontally in its corresponding demolding through groove 17-201, thereby adjusting the horizontal position of the demolding tooth 17-1 fixed on the replacement plate 17-101, ensuring that each demolding tooth 17-1 can be set between adjacent bottle bodies, thereby ensuring that the operation of peeling off the diaphragm and the bottle body can be successful.

[0030] In specific implementation, the upper parts of the four side walls of the demolding frame 17-2 are respectively provided with demolding through grooves 17-201 horizontally, and each side wall is provided with demolding teeth 17-1 to ensure that the membrane 2 can be completely separated from the bottle body 1 during the demolding process, thereby ensuring the possibility of successful operation of the process; the number of demolding teeth 17-1 is adapted to the number of bottle bodies 1, and a demolding tooth transposition structure is provided on the outside of each side wall to adjust the demolding teeth 17-1.

[0033] Driven by the horizontal driving structure of the conveying frame 16-1, it makes linear motion between the top of the demolding frame 17-2 and the discharge platform 4; in the present invention, the horizontal driving structure 15 of the conveying frame is realized based on a linear motor type module, and the slide seat of the module is fixedly connected to the conveying frame 16-1.

[0034] The bottle conveying structure 16 also includes: a conveying frame lifting structure, which includes a conveying lifting servo motor 15-1, a conveying screw 15-4 and a conveying screw pair 15-2 connected by threads;

In order to ensure the balance during lifting, two transport guide rods 15-7 are provided.

[0036] The bottle conveying structure also includes a material clamping structure, which includes: a pushing plate 16-2, a discharge positioning plate 16-4, and a pushing cylinder 16-3.

When the bottle 1 is lifted by the lifting plate 17-3 and enters the conveying frame 16-1, the pushing cylinder 16-3 is started to push the pushing plate 16-2 toward the bottle 1, and the bottle 1 placed side by side is clamped by the pushing plate 16-2 and the discharge positioning plate 16-4, ensuring that the bottle 1 without the diaphragm 2 bundle will not fall over during the process of conveying to the discharge platform 4.

[0037] In the present invention, when the diaphragm 2 and the bottle body 1 are pushed to the film stripping station from the double-sided film cutting channel 5-2, they are pushed into the film stripping frame 17-2 from the bottle inlet 17-202 and sent to the lifting plate 17-3. Then, the lifting plate lifting structure 17-4 is started to lift the lifting plate 17-3, the bottle body 1, and the diaphragm 2 at the same time until the lowest end of the bottle body 1 is located at the top of the film stripping frame 17-2; in the process of the bottle body 1 and the diaphragm 2 being lifted by the lifting plate 17-3 The demoulding teeth 17-1 pass through the lifting plate 17-3 from the demoulding teeth avoidance groove, so that the height of the lifting plate 17-3 can be higher than the demoulding teeth 17-1, and at the same time, the demoulding teeth 17-1 between adjacent bottles clamp the diaphragm 2, so that the diaphragm 2 is located at the bottom of the bottle body 1; after the bottle body 1 completely enters the inner cavity of the conveying frame 16-1, the lifting plate lifting structure 17-4 starts in the reverse direction, driving the lifting plate 17-3 back to the default position, and at the same time, the cylinder 16-3 is pushed to start After the bottle 1 is lifted up to the preset position, the servo motor 15-1 for transporting and lifting stops, and the horizontal driving structure 15 of the transport frame starts to drive the transport frame 16-1 to return to the preset position at the top of the stripping frame 17-2, so as to prepare for the next round of stripping operation.
