Description

Technical Field

[0001] The utility model relates to the technical field of food bag processing, in particular to a heat sealing device used for food bag processing. Background Art

[0002] Food bags are a type of packaging design. In order to preserve and store food in our daily lives, product packaging bags are produced. Food packaging bags refer to film containers that are in direct contact with food and are used to hold and protect food. The food bags are sealed by heat sealing devices, which not only facilitates transportation, but also helps to preserve food during transportation.

[0003] The existing Chinese patent with announcement number CN217944507U discloses a heat sealing device for producing food-grade plastic bags, including a base, a mounting frame installed on the top of the base, an electric telescopic rod installed on the mounting frame, a bottom plate installed at the bottom of the extended end of the electric telescopic rod, and a heating block installed on the bottom surface of the bottom plate. Mounting plates are installed on the outer walls on both sides opposite to each other, and movable racks that can move in contact with the bottom surface of the heating block are installed on the front of the two mounting plates.

[0004] Although the above scheme can automatically scrape off the plastic bag stuck to the bottom of the heating block after heat sealing is completed, thereby reducing the trouble caused by sticky materials, irritating gases are easily generated when the food bags are heat-sealed, which will pollute the working environment and affect the health of the staff. At the same time, the device uses a single heat-sealing device, which makes it impossible to heat-seal both ends and needs to be heat-sealed again. It has certain limitations and therefore does not meet existing needs. In this regard, we propose a heat-sealing device for food bag processing. Utility Model Content

The guide rod 11 can limit the moving block 12 in the axial direction, so that the rotation of the moving block 12 is converted into horizontal linear movement, so as to drive the first electric telescopic rod 5 to move;

[0032] See also Figure 1 and Figure 2 A third electric telescopic rod 8 is provided on one side of the front and rear of the conveyor belt 3, and a fixed baffle 7 is fixedly provided on the output end of the third electric telescopic rod 8.

[0034] See also Figure 1 , suction hoods 16 are installed on both sides above the conveyor belt 3, and a suction machine 19 is provided at the upper end of the main body 1. The purification chamber 18 is connected to the suction machine 19 and the suction hood 16 through an air pipe 17. After the suction machine 19 is started, the irritating gas generated by heat sealing can be sucked into the purification chamber 18 through the suction hood 16, thereby avoiding the escape of the irritating gas, and the irritating gas can be adsorbed and purified;

[0035] See also Figure 1 A transparent observation window 21 is provided at the middle position of one side of the main body 1, through which the position of the food bag can be observed before heat sealing to avoid deviation;

[0036] See also Figure 1 and Figure 2 A revolving door 2 is movably installed at the middle position of one side of the main body 1 and at the lower side of the other side. The setting of the revolving door 2 facilitates the feeding and discharging of food bags.

[0037] Working principle: when in use, place the food bag to be heat-sealed on the conveyor belt 3, and start the conveyor belt 3 to move the food bag. When the food bag moves to the lower end of the heat-sealing block 15, the first electric telescopic rod 5 and the second electric telescopic rod 6 can be started to heat-seal both ends of the food bag. The staff can also start only one of them to heat-seal one side of the food bag. Before heat-sealing, the staff can judge the position of the food bag through the transparent observation window 21. If the position of the food bag deviates, the third electric telescopic rod 8 can be started to move the fixed baffle 7, so that the food bag can be pushed and the position of the food bag can be adjusted to ensure the accuracy of heat sealing. In order to adapt to food bags of different sizes, the threaded rod 10 can be rotated by starting the servo motor 14 under the transmission of the coupling. The rotation of the threaded rod 10 will drive the moving block 12 to rotate synchronously. Since one end of the moving block 12 slides with the guide rod 11, the moving block 12 will Due to the axial limitation, the rotation of the moving block 12 will be converted into horizontal linear movement. The moving block 12 can synchronously drive the first electric telescopic rod 5 to move through the connection of the connecting block 13, so that the distance between the first electric telescopic rod 5 and the second electric telescopic rod 6 can be adjusted to adapt to food bags of different sizes, which improves practicality. When heat sealing is performed, the food bag will produce irritating gas, and the irritating gas will escape to both sides of the inside of the main body 1. At this time, the suction machine 19 can be started. The suction machine 19 can make the suction hood 16 generate suction through the air supply pipe 17, so that the irritating gas can be sucked into the purification chamber 18. The three air purification activated carbon plates 20 in the purification chamber 18 can fully purify the irritating gas, thereby effectively avoiding pollution to the workpiece environment and affecting the health of the staff. After the food bag is heat-sealed, it will be transported by the conveyor belt 3 and fall into the collection box 4 for collection, which is convenient for subsequent removal.
