[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The following will further describe this application in detail Figures 1-4 with reference to the attached drawings.

[0024] The utility model provides a sealing mechanism for a sealing bag, which includes a support frame 1 for placing the sealing bag and a sealing device 2 arranged on the support frame 1. The sealing device 2 includes an upper sealing press head 21 and a lower sealing press head 22. The upper sealing press head 21 and the lower sealing press head 22 are abutted together and driven by two servo motors 7 respectively to realize synchronous rotation. The upper sealing press head 21 abuts against the upper sealing strip of the sealing bag, and the lower sealing press head 22 abuts against the lower sealing strip of the sealing bag. During use, only need to make the upper sealing press head 21 and the lower sealing press head 22 of the sealing device 2 rotate synchronously, and the upper sealing press head 21 and the lower sealing press head 22 respectively abut against the sealing strips of the sealing bag, then the sealing of the sealing bag can be realized.

[0025] Preferably, the materials of the upper sealing press head 21 and the lower sealing press head 22 are both rubber to prevent damage to the sealing bag during sealing.

[0026] Furthermore, it includes a conveyor belt 3 arranged on the support frame 1. The sealing bag is placed on the conveyor belt 3 and moves together with the conveyor belt 3. The conveyor belt 3 is driven by a motor, and then drives the sealing bag to move, making the whole sealing machine automated without the need for manual pushing of the sealing bag.

[0027] Furthermore, it also includes a stabilizing device arranged on the support frame 1. The stabilizing device includes a tightening belt 4 and a rotating rod 5. There are two rotating rods 5 correspondingly arranged on the support frame 1. The rotating rod 5 is coaxially and fixedly connected with a guide wheel 6. The tightening belt 4 is sleeved on the two rotating rods 5 through the guide wheel 6, and the two rotating rods 5 drive the tightening belt 4 to transmit. And the lower end of the tightening belt 4 abuts against the sealing bag and transmits along the transmission direction of the conveyor belt 3. Specifically: the motor drives the rotating rod 5 to rotate, the rotating rod 5 drives the guide wheel 6 to rotate synchronously, and then drives the tightening belt 4 to transmit, so that the transmission direction of the lower end of the tightening belt 4 is the same as the transmission direction of the conveyor belt 3, and at the same time ensure that the lower end of the tightening belt 4 can abut against the sealing bag and move together with the sealing bag.

[0028] Preferably, the number of the tightening belts 4 is two. The two tightening belts 4 are used to abut against both ends of the sealing bag to prevent the overall force of the sealing bag from being unbalanced. And the tightening belt 4 is an elastic rubber belt to prevent the tightening belt 4 from crushing the items inside the sealing bag.

[0029] The following is the overall working principle of the utility model:

[0030] When the sealing bag needs to be sealed, just place the sealing bag to be sealed on the conveyor belt 3 (the end of the sealing bag with the sealing strip faces the sealing device 2) and move along with the conveyor belt 3. When it moves to the stabilizing device, the lower end of the pressing belt 4 will abut against the sealing bag and be conveyed along with the conveyor belt 3. Then, when it moves to the sealing device 2, the upper sealing press head 21 of the sealing device 2 will abut against the upper sealing strip of the sealing bag, and the lower sealing press head 22 will abut against the lower sealing strip of the sealing bag. Moreover, the upper sealing press head 21 and the lower sealing press head 22 rotate synchronously to press the seal of the sealing bag, thus realizing the sealing of the sealing bag. It should be noted here that when the sealing bag moves to the sealing device 2, the lower end of the pressing belt 4 of the stabilizing device still abuts against the sealing bag to prevent the sealing bag from being misaligned during sealing, resulting in the problem that the bag cannot be completely sealed. In summary, the utility model does not require manual sealing of the sealing bag, and finally can improve the efficiency of the sealing work.
