Description

Technical Field

[0001] The utility model relates to the technical field of food packaging, and more particularly to a sealing device for a food packaging bag. Background Art

[0002] Plastic-packaged food has become widely circulated and has entered every household. After the food is packaged and sealed in plastic bags, it needs to be put into plastic bags and then sealed to isolate the food from external debris and make it convenient to carry and sell.

[0003] When sealing plastic packaging bags, most devices use a thermoplastic packaging method to seal the opening of the plastic packaging bag. However, when sealing the plastic bag, heating and pressurizing the plastic bag may cause the molten plastic to condense into particles and fall into the plastic packaging bag, posing a certain safety hazard to food.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a food packaging bag sealing device.

[0006] The above technical purpose of the present utility model is achieved through the following technical scheme: it includes a fixing device, a packaging bag is fixed between the two fixing devices, the fixing device is slidably connected to a transverse guide rail, the end of the transverse guide rail away from the fixing device is fixedly connected to a column, a sliding rod is slidably connected between the two columns, a plastic sealing device is installed at the lower end of the sliding rod, the plastic sealing device includes a plastic sealing strip and an extrusion plate, and the extrusion plate is slidably connected to the plastic sealing device.

[0007] By adopting the above technical solution, the packaging bag is fixed in the entire device by a fixing device, and the packaging bag is fixed under the plastic sealing device. The two sides of the packaging bag are fixed by the fixing device. The fixing device is installed on the transverse guide rail and can be moved laterally by the transverse guide rail. When the fixing device moves to the lower end of the plastic sealing device, the plastic sealing device plastic seals the opening of the packaging bag. The plastic sealing device includes an extrusion plate and a plastic sealing strip. The plastic sealing strip plastic seals the opening of the packaging bag. The extrusion plate can move up and down the inner side wall of the plastic sealing device. After the plastic sealing strip hot-melts the opening of the packaging bag, the extrusion plate moves upward to squeeze the plastic softened by the hot melt and push it up, so that the plastic softened by the hot melt will not drip into the food.

[0008] The utility model is further configured as follows: the extrusion plate is located at the lower end of the plastic sealing strip.

[0009] By adopting the above technical solution, the plastic sealing strip heats and softens the plastic, and the extrusion plate arranged at the lower end can squeeze the melted plastic upward, thereby increasing and reducing the risk of the melted plastic dripping into the food.

[0010] The utility model is further configured as follows: the opposite surface of the extrusion plate is configured as an inclined surface.

[0011] By adopting the above technical solution, the extrusion plate is an inclined surface, sloping from top to bottom, with less space between the lower ends, and the upper end can better extrude the softened plastic upward.

[0012] The utility model is further configured as follows: slide rails are provided on opposite surfaces of the two upright posts, and the two slide rails are slidably connected with the slide rods.

[0013] By adopting the above technical solution, the slide bar moves up and down through the slide rail, thereby controlling the height of the slide bar on the column.

[0014] The utility model is further configured such that: the fixing device comprises two clamping blocks, and the two clamping blocks (221) move in a relative horizontal direction through the fixing device.

[0015] By adopting the above technical solution, the fixing device is provided with two clamping blocks, and the fixing device reduces the gap between the two clamping blocks to clamp the packaging bag.

[0016] The utility model is further configured as follows: guide grooves are provided on opposite sides of the transverse guide rails, and the fixing device slides through the guide grooves.

[0017] By adopting the above technical solution, the fixing device moves back and forth through the guide groove provided in the transverse guide rail, so that the packaging bag can be clamped and moved to complete the flow automation.

[0018] In summary, the utility model has the following beneficial effects: the plastic sealing at the opening of the packaging bag is completed by installing an extrusion plate and a plastic sealing strip in the plastic sealing device. When the extrusion plate moves upward, the plastic sealing strip squeezes the melted softened plastic of the packaging bag upward to prevent the liquefied plastic flowing down when the plastic sealing strip seals the packaging bag from falling into the food.
