Description

Technical Field

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

[0002] Food packaging is an integral part of food commodities and plays a vital role in the food industry. It refers to the use of appropriate packaging materials, containers and packaging technologies to wrap food so that the food can maintain its value and original state during transportation and storage. Currently, plastic materials are generally used to package food and then the plastic packaging bags are sealed.

[0003] The two hot pressing plates on the current sealing equipment are both exposed to the outside and need to be powered on for heating when in use. When the operator is sealing the food, if there is an accidental touch or improper operation, it is easy to cause burns to the hands.

[0004] In the prior art, a Chinese patent with publication number CN219821955U has been proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a food bag sealing device for food packaging, comprising: a sealing machine body, a protective assembly provided on both sides of the surface of the sealing machine body, the protective assembly including a connecting plate, a slot formed on the surface of the connecting plate, a block provided inside the slot, and a protective plate connected to the surface of the block; and a fixing assembly provided at the bottom of the connecting plate. The utility model provides a food bag sealing device for food packaging, wherein the protective assembly with the fixing assembly provided on both sides of the surface of the sealing machine body can protect both sides of the heating plate on the sealing machine body, thereby preventing the operator from accidentally touching the plate and causing hand injuries during operation. However, generally, plastics will generate harmful gases after heating. Therefore, during the process of heating and sealing plastic packaging bags, the harmful gases can easily enter the packaging bag and affect the food, and further easily affect the human body of the person eating the food. Utility Model Content

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

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] The cam is fixedly mounted on the support frame of the sealing machine body and is adapted to engage the cam face of the sealing machine body and to engage with the cam face of the sealing machine body to engage with the support frame of the sealing machine body.

[0008] Generally, plastics will produce harmful gases after heating. Therefore, during the process of heating and sealing plastic packaging bags, harmful gases can easily enter the packaging bags and affect food, and then easily affect the human body of people who eat them. In this application, by installing an electric push rod, the piston plate can be driven to move to the top and bottom inside the processing box. When the piston plate moves toward the top, it can form an adsorption force to one side on the baffle, thereby driving the baffle to move to one side, and adsorbing the harmful gases generated during the sealing process of the plastic packaging into the interior of the processing box. When the piston plate moves toward the bottom, it can form a thrust to both sides on the partition and the baffle, so that the partition is away from the connecting plate and the baffle is close to the inner wall of the processing box, thereby guiding the harmful gases to one side. By installing a filter, the harmful gases can be preliminarily filtered when they pass through the inside of the fixed plate. By installing an activated carbon net, the harmful gases can be adsorbed and purified when they pass through the inside of the connecting plate, thereby achieving adsorption and purification of the harmful gases generated in the process of food packaging, and improving the safety performance of the sealing of the sealing machine body.

[0009] A further improvement of the technical solution of the present utility model is that: the sealing component includes a pressure plate, the surfaces on both sides and both ends of the pressure plate are in contact with the inner wall of the sealing machine body, a pressure block is fixedly installed on the top of the pressure plate, the top of the pressure block extends out of the interior of the sealing machine body, and the top of the pressure plate at both ends of the pressure block is fixedly connected to a spring group, and the top surface of each spring group is fixedly connected to the inner wall of the sealing machine body.

[0010] The above-mentioned technical solution is adopted. In this solution, by pressing the pressure block toward the bottom, the pressure plate can be driven to move toward the bottom, and at the same time, cooperate with the heating strip to achieve the sealing of the food plastic bag. When the operator's hand is separated from the pressure block, the elastic force of the spring group itself can form a pulling force toward the top on the pressure plate, thereby eliminating the need for the operator to manually move the pressure plate to the top, thereby improving the sealing efficiency.

[0011] A further improvement of the technical solution of the present utility model is that a guide groove is provided inside the pressing plate.

[0012] By adopting the above technical solution, in this solution, by opening a guide groove, the harmful gas generated near the other side of the heating strip can be guided to the interior of the processing box, thereby improving the effect of adsorbing the harmful gas and further improving the safety performance of the sealing of the sealing machine body.

[0013] A further improvement of the technical solution of the present invention is that a first sealing gasket is attached to the surface of the other side of the baffle, and the surface of the other side of the first sealing gasket is tightly fitted to the inner wall of the processing box.

[0014] By adopting the above-mentioned technical solution, the baffle can be connected and contacted with the inner wall of the processing box by installing a first sealing gasket, thereby reducing the gap between the other side surface of the baffle and the inner wall of the processing box, reducing the possibility of harmful gases leaking out from the other side of the processing box after entering the interior of the processing box, thereby improving the effect of harmful gas treatment.

[0015] A further improvement of the technical solution of the present invention is that a plurality of first balls are fixedly installed inside the baffle plate outside each fixing rod, and each first ball is respectively fitted with the outer surface of each fixing rod.

[0016] By adopting the above technical solution, the contact area between the inner wall of the baffle and the fixed rod can be reduced by installing the first ball, and during the movement of the fixed rod, the first ball can roll synchronously with the fixed rod, thereby reducing the wear of the fixed rod and the baffle and extending the service life of the fixed rod and the baffle.

[0017] A further improvement of the technical solution of the present invention is that a second sealing gasket is attached to the surface of the other side of the partition, and the surface of the other side of the second sealing gasket is tightly fitted with the surface of one side of the connecting plate.

[0018] By adopting the above technical solution, the partition can be connected to the surface of one side of the connecting plate by installing a second sealing gasket, thereby reducing the gap between the other side surface of the partition and the surface of one side of the connecting plate, reducing the possibility of harmful gases entering the processing box and then flowing back to the other side of the processing box, thereby improving the effect of harmful gas treatment.

[0019] A further improvement of the technical solution of the present invention is that a plurality of second balls are fixedly mounted inside the partitions outside the connecting rods, and each second ball fits against the outer surface of each connecting rod.

[0020] The above-mentioned technical solution is adopted. In this solution, the contact area between the inner wall of the partition and the connecting rod can be reduced by installing a second ball, and during the movement of the connecting rod, the second ball can roll synchronously with the connecting rod, thereby reducing the wear of the connecting rod and the partition and extending the service life of the connecting rod and the partition.

[0021] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

By installing an electric push rod, it can drive the piston plate to move toward the top and bottom inside the processing box, thereby driving the baffle and partition to move, and adsorbing the harmful gas generated during the sealing process of the plastic packaging into the interior of the processing box. At the same time, the filter screen and activated carbon net are used to filter and adsorb the harmful gas to prevent the gas from entering the packaging bag and affecting the food, thereby improving the safety performance of the sealing of the sealing machine body.

[0023] 2. The utility model provides a sealing device for food packaging. By providing a guide groove, the harmful gas generated near the other side of the heating strip can be easily guided to the interior of the processing box, thereby improving the effect of adsorbing the harmful gas and further improving the safety performance of the sealing of the sealing machine body.
