Description

Technical Field

[0001] The utility model relates to the technical field of food packaging equipment, in particular to a plastic packaging sealing device for food. Background Art

[0002] Plastic packaging bags are indispensable items in the daily life of modern people. They are often used to hold other items. They are widely used because of their low price, light weight, bright colors, resistance to falling, economical and durable, easy to carry and store. In the food production process, it is often necessary to seal the mouth of the packaging bag. At present, the sealing of the bag mouth is mainly carried out by a sealing device. The sealing device mainly refers to a device that uses electric heating to melt the bag mouth and presses the bag mouth of the packaging bag through a pressing plate.

[0003] At present, with the relaxation of epidemic control, many industries have gradually returned to their original state. In the food industry, many self-operated food stores have been added. Most of these small food stores produce hot-selling foods such as cakes, stewed food, and biscuits. At the same time, in order to ensure food hygiene and safety, food packaging bags are used for sealing and packaging, so as to better sell and preserve. At present, traditional food stores package food with small portable sealing devices, which will ensure that the bag opening is inserted into the sealing groove and sealed by heating and extrusion;

[0004] The current traditional small-scale sealing equipment requires workers to manually fill and then manually seal. This method makes the packaging efficiency of the produced food low. The labor workload for packaging handmade food is large, which is not conducive to the long-term sealing and use of food stores. Therefore, a device that can automatically seal after filling and placing is needed, so that the device can semi-automatically seal and improve the packaging efficiency of food stores. Summary of the invention

[0005] The purpose of the utility model is to provide a plastic packaging sealing device for food to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plastic packaging sealing device for food, comprising: a device body, a heating structure, a pushing structure and an adjusting structure; a placement groove is opened in the middle of the device body; the heating structure is arranged on the upper surface of the device body, and the heating structure comprises a first sealing strip connected to the top of the device body by screws and a heating rod inserted in a slot on one side of the first sealing strip; the pushing structure is arranged inside the device body, and the pushing structure comprises an electric cylinder connected to the inner wall of the device body by a fixing ring, and a second sealing strip welded to one end of the electric cylinder push rod; the adjusting structure is arranged inside the device body, and the adjusting structure comprises a support column welded to the inner wall of the device body, a support rod inserted in the support column socket, an adjusting plate welded to one end of the support rod, and a support plate welded to one side of the adjusting plate.

[0007] By adopting the above technical solution, after the filled packaging bag is placed with its opening facing upward in the middle position of the support plate, the electric cylinder pushes the second sealing strip to press the opening of the packaging bag against the first sealing strip, and the sealing process can be quickly completed under the action of pressure and heating by the heating rod. The worker only needs to put the filled packaging bag in place, and the packaging bag can be automatically heat-sealed, thereby improving the worker's efficiency in sealing a single packaging bag, reducing the worker's workload of filling and manual sealing, and is conducive to long-term sealing processing and use in food stores.

[0008] Preferably, the pushing structure further comprises a positioning column welded on the inner wall of the device body and a positioning rod welded on one side of the second sealing strip, and the positioning rod is inserted into the insertion hole of the positioning column.

[0015] By adopting the above technical solution, by designing the number and grouping of the digital inserts, and engraving the date numbers and Chinese characters of the year, month and day, a production date indentation with the year, month and day can be formed after extrusion. When producing packages on different dates, the digital inserts can be replaced according to the specific date so that the device can accurately adjust the date. By pressing the production date at the heat seal, consumers can find relevant information more easily, thereby helping them make more informed purchasing decisions.

[0016] Preferably, the first sealing strip and the second sealing strip are located in corresponding positions, and a plurality of shallow pressing grooves are formed on the opposite surfaces.

[0017] By adopting the above technical solution, by setting the relative positions of the first sealing strip and the second sealing strip, and by providing a plurality of shallow pressure grooves, the packaging bag can be horizontally aligned with the first sealing strip and pressed to ensure the sealing effect of the packaging bag. At the same time, the plurality of shallow indentations can form a more secure seal for the packaging bag, so as to improve the firmness of the seal and avoid the opening phenomenon caused by shaking during transportation.

[0018] Preferably, an inclined plate is welded to the inner wall of the placement groove, and one end of the inclined plate is located at one end of the support plate.

[0019] By adopting the above technical solution and welding an inclined plate in the placement groove, the packaging bag can be manually pushed and slid to the side for storage in a collection box after sealing, without having to take down the packaging bag for placement, thereby improving the continuity of sealing between different packaging bags.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] After the filled packaging bag is placed with its opening facing upward in the middle of the support plate, the electric cylinder pushes the second sealing strip to press the opening of the packaging bag against the first sealing strip. The sealing process can be completed quickly under the action of pressure and heating by the heating rod. The worker only needs to put the filled packaging bag in place, and the packaging bag can be automatically heat-sealed, thereby improving the efficiency of the worker in sealing a single packaging bag, reducing the labor of the worker in filling and manual sealing, and facilitating the long-term use of the sealing process in the food store.

[0022] By adopting the plug-in method, the digital insert strips with different numbers can be replaced according to the production date and inserted into the slot, so that a row of digital insert strips can form the production date. When extruding and sealing, the production date indentation can be pressed out at the sealing portion under the action of heating, and there is no need to write the production date later, thereby reducing the packaging production process and improving the processing efficiency of food packaging;

[0023] The screw can be rotated by using a crank, so that the adjustment plate can move horizontally under the thrust of the screw rotation. The spacing can be adjusted according to the amount of food loaded in the packaging bag, so that the food in the packaging bag after placement can be distributed in the entire packaging bag, and the opening at the seal can be reduced, which is conducive to the second sealing strip pushing the packaging bag seal to the first sealing strip for sealing, thereby improving the sealing effect.
