During operation, after the packaging bag moves to the top of the lifting frame 2, the lifting device is started, thereby driving the lifting frame 2 to rise. When the lifting frame 2 is rising, the rubber negative pressure pad 7 therein remains stationary, thereby allowing the rubber negative pressure pad 7 to generate negative pressure through the suction port 3 and the negative pressure circular groove 4, so that it adsorbs the packaging bag on the lifting frame 2, and then limits the packaging bag to be sealed to prevent it from being skewed during sealing, thereby improving the appearance of the finished product when the device is sealed, reducing sealing failures, and further improving the use effect of the device.

[0028] Further, such as Figure 4 As shown, the second stabilizing column 12 is slidably connected to the center of the second connecting frame 11; the second stabilizing column 12 is fixed to the lifting frame 2; the limiting seats 13 are fixed on both sides of the inner side of the sealing frame 1 and at positions corresponding to the second connecting frame 11; the second connecting frame 11 fits with the limiting seats 13. During operation, when the lifting frame 2 rises through the lifting assembly, the rubber negative pressure pad 7 is stabilized by the second stabilizing column 12 in cooperation with the first stabilizing column 10, further improving the effect of generating negative pressure in the negative pressure circular groove 4, and the contact between the second connecting frame 11 and the limiting seat 13 makes the rubber negative pressure pad 7 remain motionless in the negative pressure circular groove 4, and then when the lifting frame 2 rises, the negative adsorption capacity in the negative pressure circular groove 4 is stable.

[0029] Further, such as Figure 2 and Figure 3As shown, negative pressure nets 14 are fixed at the top of both sides of the lifting frame 2 and at positions corresponding to the suction ports 3. During operation, when the negative pressure circular grooves 4 and the suction ports 3 generate negative pressure on the packaging bag on the lifting frame 2 to fix it, in order to reduce damage to the packaging bag and maintain the suction effect of the packaging bag, the negative pressure nets 14 can further improve the suction and fixing effect of the packaging bag, thereby further improving the use effect of the device.

[0030] Further, such as Figure 5 As shown, the lifting assembly includes a lifting bidirectional screw 15, an adjustment seat 16 and a lifting column 17; the lifting bidirectional screw 15 is rotatably connected to the center of the bottom end of the sealing frame 1; both ends of the lifting bidirectional screw 15 are threadedly connected to the adjustment seat 16; and the lifting column 17 is fixed to the top of the adjustment seat 16. During operation, after the packaging bag is moved onto the lifting frame 2, the lifting bidirectional screw 15 rotates, so that the lifting bidirectional screw 15 drives the adjustment seat 16 thereon to move toward the direction close to the lifting frame 2. The two lifting columns 17 thereon are provided to improve the stability of the lifting frame 2 in rising and falling, and further improve the sealing effect of the packaging bag.

[0031] Further, such as Figure 5 As shown, the lifting assembly also includes a connecting ring 18, a lifting seat 19, a lifting square column 20 and a transmission motor 21; both sides of the lifting column 17 are rotatably connected with the connecting ring 18; the top of the connecting ring 18 is fixed with the lifting square column 20; the end of the lifting square column 20 close to the lifting frame 2 is rotatably connected with the lifting seat 19; the end of the lifting seat 19 close to the lifting frame 2 is fixed to the lifting frame 2. During operation, when the adjustment seat 16 moves toward the direction close to the lifting frame 2, through the transmission of the lifting square column 20 and the lifting seat 19, the lifting effect of four points at the same time is further improved, and the use effect of the device is improved.

[0032] Further, such as Figure 1 and Figure 2 As shown, a transmission frame 22 is arranged at the center of the lifting frame 2; both ends of the transmission frame 22 are fixed to the sealing frame 1; a conveyor belt 23 is arranged inside the transmission frame 22; a laser sealer 24 is arranged on one side of the sealing frame 1 and corresponding to the lifting frame 2.

When the lifting frame 2 rises through the lifting assembly When the lifting frame 2 is lifted up by the lifting assembly, the rubber negative pressure pad 7 is stabilized by the second stabilizing column 12 in cooperation with the first stabilizing column 10, and the negative pressure effect in the negative pressure circular groove 4 is further improved. The contact between the second connecting frame 11 and the limiting seat 13 keeps the rubber negative pressure pad 7 stationary in the negative pressure circular groove 4, and when the lifting frame 2 is lifted up, the negative pressure circular groove 4 is stabilized. 4 has a stable negative adsorption capacity. When the negative pressure circular groove 4 and the adsorption port 3 generate negative pressure to fix the packaging bag on the lifting frame 2, in order to reduce the damage of the packaging bag and maintain the adsorption effect of the packaging bag, the negative pressure net 14 can further improve the adsorption and fixing effect of the packaging bag, and further improve the use effect of the device. When the packaging bag is moved to the lifting frame 2, the lifting bidirectional screw 15 is rotated to drive the adjusting seat 16 thereon to move toward the direction close to the lifting frame 2. The two lifting columns 17 thereon are arranged to improve the The stability of the rise and fall of the high lifting frame 2 further improves the sealing effect of the packaging bag. When the adjustment seat 16 moves toward the direction close to the lifting frame 2, through the transmission of the lifting square column 20 and the lifting seat 19, the effect of four-point simultaneous lifting can further improve the stability of the lifting and lowering of the lifting frame 2, and improve the use effect of the device.
