Description

Technical Field

[0001] This utility model relates to the field of sealing machine technology, specifically a sealing machine for food plastic packaging bags. Background Technology

[0002] Food plastic packaging bags are plastic containers used for food packaging, transportation and storage. According to the application scope, they can be divided into ordinary food packaging bags, vacuum packaging bags, gas-filled packaging bags, boil-in-water packaging bags, retort packaging bags and functional packaging bags.

[0003] Patent CN218665219U discloses a sealing machine for dried fruit packaging bags. It includes a sealing machine body with a base plate at its bottom and a sealing assembly at its top. The sealing assembly is located above the base plate, and a movable plate and a support plate are located above the base plate. This device is bolted to the top of a lifting rod. When the lifting mechanism is activated, the lifting rod provides an upward force to the support plate, causing the support plate to lift the large packaging bag. This process eliminates the need for manual lifting of the packaging bag during sealing, saving labor and increasing the degree of automation, thereby improving the sealing efficiency and practicality of dried fruit packaging bags.

[0004] However, the device has a certain height for the support plate, which means that the sealing personnel need to move the fruit packaging on the support plate when placing it. In addition, even after the packaging bag is placed on the support plate, the support plate still needs to be moved behind the sealing component and then moved up again. The process is cumbersome and affects the sealing efficiency. Therefore, a food plastic packaging bag sealing machine is proposed to solve the problem that the existing sealing machine is not convenient for moving and sealing the packaging.

[0015] (III) Beneficial Effects

[0016] 1. This food plastic packaging bag sealing machine places the plastic packaging bag containing food in a low-positioned placement box. Then, a servo motor drives a lead screw, which, under the action of guide rods between fixed blocks, moves the moving seat along the slope of the fixed seat, along with the placement box. After moving the placement box and packaging bag to a suitable position, the sealing personnel place the packaging bag sealing device in the sealing assembly for sealing. The structure is simple, the operation is convenient, and the sealing efficiency of packaging bags is improved, solving the problem that existing sealing machines are difficult to conveniently move and seal packaging.

[0017] 2. This food plastic packaging bag sealing machine, when placing the food-containing packaging bag into the placement box, uses the limiting block in the limiting groove to adjust the two adjusting plates to contact the two ends of the packaging bag. During the process, under the action of the adjusting groove, the limiting screw moves with the adjusting plate. Then, after tightening the limiting nut to fix the position of the adjusting plate, the stability of the packaging bag can be ensured. At the same time, the smooth guide slope improves the convenience of placing the packaging bag into the placement box. Attached Figure Description
