Description

Technical Field

[0001] The utility model relates to the technical field of sealing machines, in particular to a continuous sealing machine for food bag packaging. Background Art

[0002] Sealing machines are machines that seal containers filled with packaging materials. After the product is placed in the packaging container, in order to keep the product sealed and preserved, maintain product quality, and prevent product loss, the packaging container needs to be sealed. This operation is completed on the sealing machine. Simply put, a sealing machine refers to a machine that seals the container after the product is placed in the packaging container.

[0003] Since food needs to be transported to the heating port of the sealing machine through a conveyor belt during packaging, and one sealed end must correspond to the direction of the sealing machine. In the prior art, when food packaging bags are transported on the conveyor belt, due to the lack of components to intervene in the food bags, multiple food bags are placed unevenly, so that the sealed ends of the packaging bags cannot be just fed into the heating port of the sealing machine, which will lead to poor sealing effects of the food packaging bags, thereby reducing the overall sealing efficiency of the sealing machine and insufficient practicality. Therefore, it is necessary to redesign the food bag packaging continuous sealing machine to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 The continuous sealing machine for food bag packaging includes a transport frame 1 and a transport belt 2. A moving frame 3 is fixedly installed on the upper end surface of the transport frame 1. A positioning plate 5 is fixedly connected to the inner wall of the moving frame 3 through a connecting mechanism. The connecting mechanism includes a connecting rod 4 fixedly installed on the inner wall of the moving frame 3. The end of the connecting rod 4 is fixedly connected to the outer wall of the positioning plate 5. A screw 6 is rotatably installed inside the moving frame 3. A motor 7 connected to the screw 6 is fixedly installed on the outer wall of the moving frame 3. A moving sleeve 9 is threadedly installed on the outer wall of the screw 6. A limiting rod 8 is fixedly installed on the inner wall of the moving frame 3. The limiting rod 8 slides through the moving sleeve 9. The bottom wall of the moving sleeve 9 is fixedly connected to a push plate 11 through a connecting mechanism. The connecting mechanism includes a connecting rod 10 fixedly installed on the bottom wall of the moving sleeve 9, and the end of the connecting rod 10 is fixedly connected to the outer wall of the push plate 11.

[0023] A cylinder 13 is fixedly installed on the inner wall of the push plate 11 through a supporting mechanism, and the supporting mechanism includes a supporting plate 12 fixedly installed on the inner wall of the push plate 11, and the cylinder 13 is fixedly installed on the bottom wall of the support plate 12. The telescopic end of the cylinder 13 is fixedly connected to a lower pressure plate 14, and a support frame 15 is fixedly installed on the upper end surface of the transport frame 1. The bottom wall of the support frame 15 is fixedly connected to an air cooler 17 through a lifting mechanism. The lifting mechanism includes an electric push rod 16 fixedly installed on the bottom wall of the support frame 15, and the telescopic end of the electric push rod 16 is fixedly connected to the upper end surface of the air cooler 17. A blowing pipe 18 is fixedly installed on the outer wall of the outlet pipe of the air cooler 17, and a blowing port connected to the interior is opened on the outer wall of the blowing pipe 18.

[0024] When the utility model is used, the food bags are placed one by one on the upper end surface of the conveying belt 2 for transportation. During the transportation process, the motor 7 drives the screw rod 6 to rotate, and the screw rod 6 drives the moving sleeve 9 to move by cooperating with the limiting rod 8. During the movement of the moving sleeve 9, the pushing plate 11 can be driven to move by the connecting rod 10, so that the pushing plate 11 can push the food bags to move on the upper end surface of the conveying belt 2, and in cooperation with the positioning plate 5, multiple food bags are placed on the same straight line and aligned, thereby preventing multiple food bags from being placed unevenly and affecting the sealing effect;

[0025] And before sealing, the cylinder 13 can drive the lower pressure plate 14 to move downward, so that the bottom wall of the lower pressure plate 14 presses down the food bag, thereby preventing the food bag from adhering to the heating plate of the sealing machine after the sealing work is completed, thereby preventing the food bag from being torn by the sealing machine. When the sealing work is completed, the conveyor belt 2 can drive the food bag to move below the support frame 15. At this time, the electric push rod 16 can drive the cold air fan 17 to move up and down, so that the distance between the blowing pipe 18 and the food bag can be adjusted. Subsequently, the cold air fan 17 can be started to blow cold air into the blowing pipe 18, and the cold air is blown out from the blowing pipe 18 through the blowing port, thereby blowing the food bag after hot-pressing sealing, increasing its cooling efficiency, and avoiding the pressure-sealed ends of multiple food bags from sticking together.
