DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the embodiments.

[0026] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0027] See also Figures 1 to 7 The utility model provides an airbag bag edge sealing device, including a processing table 10; a placement groove 101 is provided in the middle of the processing table 10 for placing the airbag bag 20 to be processed, guide columns 11 are provided at the four corners of the processing table 10, and slots 12 are provided between adjacent guide columns 11, and the slots 12 extend to the interior of the processing table 10, and a slide groove 13 is provided at the connection between the slot 12 and the interior of the processing table 10, and the slide groove 13 is connected to the slot 12.

[0028] Fixed plates 14 are provided on both sides of the processing table 10, and the fixed plates 14 are used to fix the cylinder 15. The telescopic rod 151 of the cylinder 15 passes through the fixed plate 14. The telescopic rod 151 is connected with a pressing plate 16 for crimping the airbag bag 20. The pressing plate 16 can move up and down under the telescopic action of the cylinder 15.

[0029] Guide holes 161 are provided at the four corners of the pressing plate 16, and the pressing plate 16 is inserted into the guide column 11 through the guide holes 161. The pressing plate 16 is slidably connected to the guide column 11 through the guide holes 161. A heating block 162 is provided on the side of the pressing plate 16 close to the placement slot 101, and a spring 163 is provided between the heating block 162 and the pressing plate 16. One end of the spring 163 is connected to the pressing plate 16, and the other end is connected to the heating block 162. The heating block 162 can compress the spring 163 to move closer to the pressing plate 16. An insert plate 164 is provided at the position of the pressing plate 16 corresponding to the slot 12. The size of the insert plate 164 is the same as that of the slot 12, ensuring that the insert plate 164 can be inserted into the slot 12 when it moves downward close to the placement slot 101.

[0030] A heating block 17 is provided in the slide groove 13, and the heating block 17 is slidably connected to the slide groove 13. The surrounding heating blocks 17 are close to each other to form a heating ring for installation in the placement groove 101. The parts of the surrounding heating blocks 17 leaking out of the slide groove 13 cooperate with the heating block 162 on the pressing plate 16 to heat the airbag bag 20 and heat-seal the two layers of the airbag bag 20.

[0031] A second slide groove 171 is provided on one side of the heating block 17 close to the slot 12, and a sliding surface 172 is provided in the second slide groove 171. The sliding surface 172 is inclined relative to the second slide groove 171, so that when the plug plate 164 moves downward and contacts the sliding surface 172, the plug plate 164 can slide along the sliding surface 172. A second spring 173 is provided on the back side of the heating block 17, one end of the second spring 173 is connected to the heating block 17, and the other end of the second spring 173 is connected to the slide groove 13. The heating block 17 can compress the second spring 173 to shrink toward the slide groove 13.

[0032] The airbag bag 20 is placed on the heating block 17 in the placement groove 101. When the pressure plate 16 moves downward under the action of the cylinder 15, the heating block 162 is close to the heating block 17 to heat and seal the airbag bag 20 in the middle. When the pressure plate 16 continues to move downward, the heating block 162 compresses the spring 163 and approaches the pressure plate 16, while the plug plate 164 is inserted into the slot 12 and the slide groove 171. The plug plate 164 moves along the sliding surface 172 to make the heating block 17 in the placement groove 101 shrink toward the surrounding slide grooves 13.

[0033] A ball 174 is provided at the connection between the heating block 17 and the slide groove 13 to reduce the friction of the heating block 17 sliding in the slide groove 13. A conveyor belt 18 is provided at the bottom of the placement groove 101 to receive the airbag bag 20. When the heating block 17 shrinks into the surrounding slide grooves 13, the airbag bag 20 loses the supporting force of the heating block 17 and falls onto the conveyor belt 18 at the bottom and is transported by the conveyor belt 18.

[0034] The working principle and use process of the utility model are as follows: First, the airbag bag 20 is placed on the heating block 17 in the placement groove 101, and the telescopic rod 151 is extended by the cylinder 15 to drive the pressing plate 16 to move downward. When the pressing plate 16 moves downward under the action of the cylinder 15 until the heating block 162 is close to the heating block 17 (such as Figure 6As shown in the processing state 1, the middle airbag bag 20 is heated by the combined action of the heating block 162 and the heating block 2 17, and the two layers of the airbag bags 20 are heat-sealed. When the pressing plate 16 continues to move downward, the heating block 162 is further pressed against the heating block 2 17, and the airbag bag 20 is further sealed. At this time, the pressing plate 16 compresses the spring 163 to approach the heating block 162, inserts the plug 164 into the slot 12 and the slide groove 171, and the plug 164 moves along the sliding surface 172, pressing the heating block 2 17 to shrink into the surrounding slide grooves 13 (as shown in the processing state 1). Figure 7 As shown in processing state 2, the airbag bag 20 loses the support force of the heating block 2 17 and falls onto the conveyor belt 18 at the bottom and is transported by the conveyor belt 18.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
