[0002] During the bag-making process, the film strip needs to be heat-sealed and cut to make it into a bag shape. Heat sealing and cutting means heating the film strip to weld one end of the film strip to form a sealing weld strip to seal one end of the film strip. After the heat sealing is completed, the film strip is cut at a distance of 10 mm from the weld line of the film strip to form a single film bag with one end open and the other end sealed.

[0055] The fixing frame 100 is arranged adjacent to the film strip bag opening device (not shown in the figure), so that the sealed and cut film strip can enter the film strip bag opening device for bag opening and packaging. The heat sealing mechanism 200 and the cutting mechanism 300 are connected to the fixing frame 100 and are respectively located on opposite sides of the fixing frame 100. When the film strip enters the sealing and cutting device 10, the heat sealing mechanism 200 and the cutting mechanism 300 respectively perform heat sealing and cutting operations on the film strip. The film pressing mechanism 400 includes a heat sealing docking piece 410 and a cutting docking piece 420. The heat sealing docking piece 410 is connected to the cutting mechanism 300, and the cutting docking piece 420 is connected to the heat sealing mechanism 200. The heat sealing mechanism 200 and the heat sealing docking piece 410 jointly seal the film bag, and the cutting mechanism 300 and the cutting docking piece 420 jointly cut the film strip.

[0056] In this embodiment, the heat sealing tool 222 of the heat sealing mechanism 200 and the cutting tool 322 of the cutting mechanism 300 are staggered. When the film strip needs to be heat-sealed and cut, the film strip enters the sealing and cutting device 10, and the film pressing mechanism 400 presses the film strip to make the film strip flat and easy to seal and cut. The heat sealing tool 222 cooperates with the heat sealing docking piece 410 to heat-seal the film strip and heat-melt-seal one end of the film strip. Then, the cutting tool 322 cooperates with the cutting docking piece 420 to cut the heat-sealed film strip and cut the heat-sealed film strip so that the film strip has an open end and a closed end, which is convenient for the next workstation to pull the film strip into a bag shape.

The heat sealing assembly 220 and the cutting mechanism 300 are respectively located on opposite sides of the fixed frame 100. When the heat sealing mechanism 200 performs heat sealing on the film strip, the heat sealing drive assembly 210 drives the heat sealing assembly 220 to approach the cutting mechanism 300. The heat sealing assembly 220 and the heat sealing butt joint 410 jointly perform heat sealing on the film strip, so that the film strip is heat-melted and sealed to complete heat sealing. After the film strip is heat-sealed, the heat sealing drive assembly 210 drives the heat sealing mechanism 200 away from the cutting mechanism 300 to wait for the next round of film strip heat sealing.

[0059] In some preferred embodiments, the heat sealing assembly 220 includes a heat sealing connection structure 221 and a heat sealing cutter 222. The heat sealing connection structure 221 is connected to the power output end of the heat sealing drive assembly 210, and the heat sealing cutter 222 is connected to the heat sealing connection structure 221. The heat sealing cutter 222 and the cutting mechanism 300 are respectively located on opposite sides of the fixing frame 100.

[0061] In this embodiment, the heat sealing connecting plate 221a, driven by the heat sealing driving assembly 210, drives the heat sealing connecting column 221b and the heat sealing elastic member 221c to jointly push the heat sealing tool 222, so that the heat sealing tool 222 and the cutting docking member 420 are close to the cutting mechanism 300, or a pulling force is generated on the heat sealing tool 222, so that the heat sealing tool 222 and the cutting docking member 420 are away from the cutting structure. When the heat sealing tool 222 and the cutting docking member 420 are close to the cutting mechanism 300 and jointly perform heat sealing work on the film strip with the heat sealing docking member 410, the heat sealing elastic member 221c has a buffering effect on the cutting docking member 420, thereby making the heat sealing tool 222 more stable when heat sealing the film strip, thereby ensuring the quality of the hot melt seal of the film strip.

[0064] Embodiment 2:

[0065] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the sealing and cutting device 10 of the utility model, see Figures 1 to 4 .

[0066] The cutting mechanism 300 includes a cutting drive assembly 310 and a cutting assembly 320. The cutting drive assembly 310 is installed on the fixing frame 100. The cutting assembly 320 is connected to the power output end of the cutting drive assembly 310. The cutting drive assembly 310 drives the cutting assembly 320 to make a reciprocating motion on the fixing frame 100 relative to the heat sealing mechanism 200.

When the cutting mechanism 300 cuts the film strip, the cutting drive assembly 310 drives the cutting assembly 320 to approach the heat sealing mechanism 200. The cutting assembly 320 and the cutting docking member 420 jointly cut the film strip, thereby disconnecting the film strip and completing the cutting. After the film strip is cut, the cutting drive assembly 310 drives the cutting mechanism 300 away from the heat sealing mechanism 200 to wait for the next round of film strip cutting.

[0067] In some preferred embodiments, the cutting assembly 320 includes a cutting connection structure 321 and a cutting tool 322. The cutting connection structure 321 is connected to the power output end of the cutting drive assembly 310, and the cutting tool 322 is connected to the cutting connection structure 321. The cutting tool 322 and the heat sealing mechanism 200 are respectively located on opposite sides of the fixing frame 100. When the cutting mechanism 300 cuts the film strip, the cutting drive assembly 310 drives the cutting connection structure 321, thereby driving the cutting tool 322 to approach the heat sealing mechanism 200, so that the cutting tool 322 can cooperate with the cutting docking member 420 to cut the film strip.

[0069] In this embodiment, the cutting connecting plate 321a, driven by the cutting driving assembly 310, drives the cutting connecting column 321b and the cutting elastic member 321c to jointly push the cutting tool 322, so that the cutting tool 322 and the heat sealing docking member 410 are close to the heat sealing mechanism 200, or a pulling force is generated on the cutting tool 322, so that the cutting tool 322 and the heat sealing docking member 410 are away from the heat sealing structure. When the cutting tool 322 and the heat sealing docking member 410 are close to the heat sealing mechanism 200 and cut the film strip together with the cutting docking member 420, the cutting elastic member 321c has a buffering effect on the cutting docking member 420, so that the cutting tool 322 is smoother when cutting the film strip, thereby ensuring the quality of the film strip incision.

When the cutting mechanism 300 starts to cut the film tape, the cutting tool 322 extends out of the cutter mounting slot 411 under the drive of the cutting drive assembly 310, thereby cutting the film tape. When cutting the film tape, the cutting tool 322 enters the cutter docking slot 421 of the cutting docking piece 420, thereby ensuring that the cutting tool 322 does not damage the cutting docking piece 420 and / or the cutting tool 322 body; when the cutting mechanism 300 stops cutting the film tape and / or the heat sealing mechanism 200 starts to heat seal the film tape, the cutting tool 322 retracts into the cutter mounting slot 411, so that the cutting mechanism 300 has a compact structure and is not easy to loosen, and the cutting tool 322 can perform the cutting work normally without being easily damaged, thereby increasing the service life of the cutting tool 322.
