Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1, the sealing apparatus for a packaging bag of the embodiment includes a hot sealing die set 10 for heat-sealing an opening of the packaging bag, and the hot sealing die set 10 includes a die frame 11 and a hot die 12 mounted on the die frame 11. As shown in fig. 2 and 3, the hot press mold 12 includes an upper hot press mold 121 and a lower hot press mold 122, the upper hot press mold 121 is connected to an upper elevation cylinder 131 installed on the mold frame 11, and the lower hot press mold 122 is connected to a lower elevation cylinder 132 installed on the mold frame 11.

Specifically, as shown in fig. 3, the upper hot-pressing die 121 includes an upper die holder 1211 and an upper die head 1212, wherein the upper die holder 1211 is mounted on the lifting slide rail 111 of the die carrier 11; the upper elevating cylinder 131 is connected to the upper mold base 1211 and drives the upper thermal press mold 121 to move up and down. The lower hot press die 122 comprises a lower die holder 1221 and a lower die head 1222, and the lower die holder 1221 is installed on a lifting slide rail 112 of the die carrier 11; the lower lifting cylinder 132 is connected to the lower die base 1221 and is used to drive the lower hot-pressing die 122 to move up and down.

Further, heating mechanisms such as heating tubes are disposed inside the upper die head 1212 and the lower die head 1222, and heat insulation plates may be disposed between the upper die head 1212 and the upper die base 1211 and between the lower die head 1222 and the lower die base 1221.

In operation, the open end of the packaging bag enters between the upper and lower hot pressing

dies

121 and 122 from the front side of the packaging bag sealing device, and then the upper and lower hot pressing

dies

121 and 122 move toward each other and clamp the opening of the packaging bag, thereby achieving heat sealing of the opening of the packaging bag. In the embodiment, the packaging bag enters the hot press die 12 from the front side of the hot press die 12, i.e., the front side of the hot press die 12 is the feeding side.

With reference to fig. 1, the sealing device of the embodiment further includes a safety clamp module 20, wherein the safety clamp module 20 includes a safety clamp 22 and a clamp driving device 21 for driving the safety clamp 22 to open and close; wherein, the clamping driving device 21 can be installed on the mold frame 11, and the safety clamp 22 is arranged on the feeding side (front side in the embodiment) of the hot-pressing mold 12 for clamping the side position of the opening heat-sealing area of the packaging bag up and down. In an embodiment, the clamping driving device 21 may be a cylinder, but the present invention is not limited thereto.

As shown in fig. 4, the safety clamp 22 includes two clamping arms 221 facing up and down, the left and right ends of the two clamping arms 221 are respectively connected to one clamping driving device 21, and the two clamping driving devices 21 are respectively located at the left and right sides of the hot press die 12. The two clamp arms 221 are driven by the clamp driving device 21 to move closer to or away from each other, thereby completing the opening and closing operation of the safety clamp 22.

In the embodiment, the strip-shaped clamp 222 is disposed on each of the two clamping arms 221 of the safety clamp 22, and the strip-shaped clamp 222 is made of a material capable of withstanding hot pressing temperature. Preferably, the strip-shaped clamp 222 is detachably mounted to the clamp arm 221.

In the present invention, the length of the bar-shaped clamp 222 and the length of the clamping arm 221 may be the same or different, and the bar-shaped clamp 222 and the packing bag may be in line contact or surface contact.

When the packaging bag sealing device works, the clamping driving device 21 firstly drives the safety clamp 22 to clamp the side position (the position close to the heat sealing area on the packaging bag) of the opening heat sealing area of the packaging bag, detects whether a product in the packaging bag is clamped or not, and then the hot-pressing die 12 carries out hot-pressing sealing operation to prevent the product from being damaged by the hot-pressing die 12; after the sealing operation is completed, the hot press mold 12 is opened (the upper hot press mold 121 and the lower hot press mold 122 are separated from each other in the process), and then the safety clip 22 is controlled to open to prevent the packaging bag from adhering to the hot press mold 12.
