Film cutting stage: as shown in Figure 22, the film cutting drive mechanism 205 drives the film cutting fixed plate 201 to continue to move down, the distance between the film cutting platen 202 and the film cutting fixed plate 201 gradually decreases, and the film cutting platen 202 under the action of elastic force The film 030 is pressed down, the film cutting knife 203 stretches out through the film cutting port 204, crosses the film cutting platen 202 to cut off the film 030, forms a circular opening 242 on the film 030 and produces redundant discs 238, and the discs 238 are passed through successively. Die opening 235 , punching vertical block 233 , and feeding opening 236 fall into material frame 237 . Membrane 030 with circular opening 031 is ready for use.

Because during the film cutting process, the cut disc 238 may be deformed, and the deformed disc 238 is easy to get stuck in the inner cavity of the film cutting knife 203, which affects the subsequent film cutting. If manual cleaning is used to get stuck in the film cutting knife 203 If the disc 238 in the film needs to be cleaned continuously by personnel, and the film cutting knife 203 stuck with the disc 238 will also affect the film cutting effect.

During the die-cutting process, the film cutting knife 203 and the pushing plate 209 will be subjected to increased impact force, that is, the film 030 exerts a greater force on the film cutting knife 203 and the pushing plate 209, because the film cutting knife 203 It is sharper and breaks through the film 030, thereby completing the film cutting. The pusher rod 208 is slidingly connected to the film-cutting fixed plate 201, and the elastic support is between the pushing plate 209 and the film-cutting fixed plate 201. The pushing plate 209 converts the impact force received into elastic deformation to play a buffering role.

The lower end surface of the sealing and cutting knife 304 is higher than the lower end surface of the heat-sealing mold 303. The sealing and cutting channel 305 through which the sealing and cutting knife 304 passes, the mold support plate 301 is connected with the sealing and cutting driving mechanism 306, and the sealing and cutting driving mechanism 306 is a driving cylinder. When the sealing and cutting driving mechanism 306 drives the mold support plate 301 to move down, the sealing and cutting platen 302 and the heat sealing mold 303 are pressed onto the film 030 first, and the sealing and cutting knife 304 cuts off the film 030 through the sealing and cutting channel 305 .

The sealing and cutting process is divided into three stages, the first stage is the non-contact film stage, the second stage is the freshly contacted film stage, and the third stage is the sealing and cutting film stage.

Non-contact film stage: the sealing and cutting drive mechanism 306 drives the mold support plate 301 to move down, driving the sealing and cutting platen 302, the heat sealing mold 303 and the sealing and cutting knife 304 to move down. The distance is unchanged.

Difficult positioning, incomplete sealing due to poor positioning of the film 030 shape, the sealing film of the glue injector 025 has a high rate of good products. The use of elastic support can ensure that the heat-sealing mold 303 can stably heat-press the glue injector 025 under the action of the sealing and cutting drive mechanism 306, and the elastic support can prevent the heat-sealing mold 303 from excessively pressing the glue injector 025, avoiding the glue injector 025 The phenomenon of destruction occurs, which further improves the yield rate of the glue injector 025.
