Description

Technical Field

[0001] The invention relates to the technical field of marshmallow packaging, in particular to a marshmallow packaging and sealing machine and a use method thereof. Background Art

[0002] Marshmallow is a common snack food in life. Usually, white sugar is poured into a marshmallow machine to make sugar threads, which are then wrapped with sticks. They melt in the mouth and are named because the sugar threads are very similar to cotton wool. Existing marshmallow products usually consist of sugar balls and sugar sticks. In order to facilitate taking, plugging and unplugging and to look good, a part of the sugar stick usually leaks out. In order to ensure the sealing and hygiene standards, they usually need to be packaged and sealed.

[0003] The existing sealing method usually requires manual pressing to hold the packaging sealing position of the marshmallow, driving the sealing position to pass through the sealing machine, and the sealing machine can seal the package by hot pressing. In order to further improve the working efficiency of the marshmallow packaging and sealing work, a marshmallow packaging and sealing machine and a method for using the same are proposed. Marshmallows in packages of different sizes can be stably loaded through a sugar placing mold, and an electric clamp and a strip conveyor belt are provided as clamping components, which can stably clamp the loaded marshmallows so that they can stably pass through a heating plate to complete the sealing process. A heating plate with a U-shaped groove body is provided, which can fully fit the marshmallow and its packaging, so that the packaging structure of the candy stick leaking out can be fully sealed, and the angle of the heating plate can be adjusted to seal the packaging structure of the candy stick not leaking out, so that the sealing machine has good applicability and can be applicable to different types of marshmallow packaging structures. Summary of the invention

[0004] The present invention provides a marshmallow packaging and sealing machine and a method for using the same, which solves the problems raised by the above-mentioned prior art. The marshmallow and the packaging can be stably loaded, and a clamping component is provided to clamp and position the marshmallow stick part and the packaging part, so that the marshmallow can be sealed by a heating plate, thereby effectively improving the work efficiency of the marshmallow packaging work.

[0005] The solution of the present invention to solve the above technical problems is as follows: a cotton candy packaging and sealing machine, comprising a sealing machine body, a feeding frame, a feeding conveyor, a lower belt conveyor, a chain conveyor, an upper belt conveyor, and a side conveyor belt, the sealing machine body and the feeding frame are fixedly connected, the feeding conveyor and the lower belt conveyor are both installed at the sealing machine body and the feeding frame, the lower belt conveyor and the chain conveyor are installed at the sealing machine body, the No. 1 sugar placing mold and the No. 2 sugar placing mold can be combined into one sugar placing mold, the No. 1 sugar placing mold and the No. 2 sugar placing mold are installed one by one on the feeding conveyor At the conveyor belt of the machine, the lower belt conveyor and the lower belt conveyor are both provided with strip conveyor belts, and the lower belt conveyor and the lower belt conveyor are both provided with two strip conveyor belts, and the strip conveyor belts are sleeved on the No. 1 sugar placing mold and the No. 2 sugar placing mold, and the chain belt of the chain conveyor is evenly installed with electric clamps, and the sealing machine body is provided with a heating plate, and the sealing machine body is installed with a material guide slope, and the outer wall of the material guide slope is threadedly connected with a storage box, and the sealing machine body and the feeding frame are evenly installed with hydraulic cylinders, and the driving end of the hydraulic cylinder is fixedly connected with the side conveyor belt;

[0006] The method of use includes the following steps:

[0007] S1: After placing the marshmallows in the packaging bag, the candy stick is protruded from the packaging bag as needed, and then the packaging bag is placed in a sugar placing mold composed of a No. 1 sugar placing mold and a No. 2 sugar placing mold, one side of the packaging bag is aligned with the inner wall of the sugar placing mold, and the protruding candy stick is placed in the candy stick slot. The sugar placing mold is processed with an arc bottom structure so that the packaging bag and the marshmallow inside can be stably placed in the center position for loading;

[0008] S2: The feeding conveyor can drive the sugar placing mold to load the material evenly. The strip conveyor belt of the lower belt conveyor passes through the No. 1 sugar placing mold and the No. 2 sugar placing mold of the feeding conveyor, so that the two strip conveyor belts of the lower belt conveyor can lift the packaging bag and the marshmallow inside it out of the sugar placing mold smoothly, so as to load the material into the heating plate of the sealing machine body for the second time;

[0009] S3: The strip conveyor belt of the upper belt conveyor can flatten the mouth of the packaging bag on the upper side of the packaging bag, so as to ensure that the bag mouth is flat and not folded, and the edge sealing is flat and beautiful. The electric clamp of the chain conveyor can clamp and position the candy sticks for conveying cotton candy. According to the length of the packaging bag, the hydraulic cylinder can be started to drive the side conveyor belt to extend and retract. The conveyor belt of the hydraulic cylinder can fit with the edge of the packaging bag, so as to ensure that the other side of the packaging bag is closely fitted with the inner wall of the sugar mold to ensure verticality, thereby playing the role of the board reference. The heating plates on both sides can seal the passing packaging bags;
