[0030] When the packaging bag needs to be sealed, first open the packaging bag to be closed and push the spring pull rod 53 through the fixing clamp 5 to separate the clamp plate 52 from the fixing body 51, then put the packaging bag between the clamp plates 52, loosen the spring pull rod 53, so that the clamp plate 52 fixes the packaging bag through the elastic force of the spring pull rod 53, and fix the four sides of the packaging bag to be sealed so that it is fixed between the opposite sides of the pressing plate 46 and the extrusion plate 35.

[0031] See also Figure 2 , Figure 4 and Figure 6 The transmission plate 3 includes a transmission plate body 31, a hydraulic connecting block 32 is fixedly connected to the top of the transmission plate body 31, and sliding rod connecting blocks 37 are fixedly connected to the left and right sides of the front and rear sides of the top of the transmission plate body 31, and a hydraulic 33 is fixedly connected to the right side of the hydraulic connecting block 32. The output end of the hydraulic 33 is fixedly connected to a push-pull plate 34, and the inner walls of the front and rear sides of the push-pull plate 34 are slidably connected with sliding rods 36. The left and right ends of the two sliding rods 36 respectively penetrate the inner wall of the push-pull plate 34, and the right outer walls of the two sliding rods 36 are respectively connected to the inner walls of the two groups of sliding rod connecting blocks 37, and the two sliding rods 36 extend to the sliding rods 3 on the opposite sides of the two groups of sliding rod connecting blocks 37. The outer walls of the two gear plates 38 are fixedly connected, the opposite surfaces of the two gear plates 38 are meshed with the gears 39, the outer walls of the two gear plates 38 are meshed with the second gear plates 310, the inner walls of the two second gear plates 310 are fixedly connected with the second slide plates 311, the left and right outer walls of the two second slide plates 311 are slidably connected with the second slide plate connecting blocks 312, the left and right outer walls of the two second slide plates 311 are slidably connected to the inner walls of the two groups of second slide plate connecting blocks 312, the left ends of the two second slide plates 311 are fixedly connected to the right side of the push-pull plate 34, and the ends of the two slide bars 36 that penetrate to the left side of the push-pull plate 34 are respectively fixedly connected to the front and rear sides of the right side of the sealing plate body 41;

[0032] After the hot melt adhesive is evenly applied to the sealing part, the hydraulic press 33 is started, so that the push-pull plate 34 moves along the slide bar 36 under the push of the hydraulic press 33. Since the right outer wall of the slide bar 36 is connected to the inner wall of the slide bar connecting block 37, the movement of the slide bar 36 drives the tooth plate 38 to move, and the movement of the tooth plate 38 drives the gear 39 and the second tooth plate 310 to move. The movement of the second tooth plate 310 drives the second slide plate 311 to slide on the inner wall of the second slide plate connecting block 312. Since the left end of the second slide plate 311 is fixedly connected to the push-pull plate The right side of 34, so the movement of the second slide plate 311 plays the role of pushing the push-pull plate 34. At the same time, the fixed connection between the sealing plate body 41 and the push-pull plate 34 also moves with the movement of the push-pull plate 34. When the push-pull plate 34 moves to the left, the sealing plate body 41 moves to the right accordingly, and the packaging bag is sealed by squeezing the squeezing plate 35 and the pressing plate 46. When the push-pull plate 34 moves to the right, the sealing plate body 41 moves to the left accordingly, and the squeezing plate 35 and the pressing plate 46 separate, completing a sealing process.

[0033] Working principle: When the device is used, when the packaging bag needs to be sealed, first open the packaging bag to be closed, and then push the spring pull rod 53 through the fixing clamp 5 to separate the clamp 52 from the fixing body 51, and then put the packaging bag between the clamps 52, release the spring pull rod 53, so that the clamp 52 fixes the packaging bag through the elastic force of the spring pull rod 53, and fix the four sides of the packaging bag to be sealed so that it is fixed between the opposite sides of the pressing plate 46 and the extrusion plate 35, then start the lifting motor 4134 to rotate the vertical screw rod 4135, and the rotation of the vertical screw rod 4135 drives the nozzle connecting plate transmission block 4136 to move up and down, thereby driving the two-way nozzle 4139 to move up and down. Move down to adjust the distance between the two-way nozzle 4139 and the packaging bag to be sealed. When the two-way nozzle 4139 is adjusted to a suitable position, start the heating device of the hot melt adhesive storage bin 42 to melt the hot melt adhesive and transport it to the two-way nozzle 4139 through the feeding pipe 44 and the nozzle feeding rod 4138, and then spray it out from the two-way nozzle 4139 to seal the packaging bag. At the same time, start the motor 49 to rotate the screw rod 410. The rotation of the screw rod 410 drives the moving plate 412 to slide on the slide plate 411, thereby driving the hot melt adhesive nozzle transmission plate 413 to move, so that the two-way nozzle 4139 moves along the edge of the packaging bag to be sealed, so that the hot melt adhesive is evenly applied to the sealing position;

[0034] After the hot melt adhesive is evenly applied to the sealing part, the hydraulic press 33 is started, so that the push-pull plate 34 moves along the slide bar 36 under the push of the hydraulic press 33. Since the right outer wall of the slide bar 36 is connected to the inner wall of the slide bar connecting block 37, the movement of the slide bar 36 drives the tooth plate 38 to move, and the movement of the tooth plate 38 drives the gear 39 and the second tooth plate 310 to move. The movement of the second tooth plate 310 drives the second slide plate 311 to slide on the inner wall of the second slide plate connecting block 312. Since the left end of the second slide plate 311 is fixedly connected to the right side of the push-pull plate 34, the movement of the second slide plate 311 plays a role in pushing the push-pull plate 34, at the same time, the fixed connection between the sealing plate body 41 and the push-pull plate 34 also moves with the movement of the push-pull plate 34. When the push-pull plate 34 moves to the left, the sealing plate body 41 moves to the right accordingly, and the packaging bag is sealed by squeezing the squeezing plate 35 and the pressing plate 46. When the push-pull plate 34 moves to the right, the sealing plate body 41 moves to the left accordingly, and the squeezing plate 35 and the pressing plate 46 separate to complete a sealing process. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
