Appropriate food packaging can not only improve product quality, hygiene and convenience, and increase the storage period of food, but also make food more convenient when eaten. Especially in the current situation where the demand for intelligence is growing, if the packaging form of food can be matched with intelligent cooking equipment, it will be of great value to the intelligentization of food processing. In addition, existing packaging equipment is often complex in structure, large in size, high in cost, and inconvenient to use. Summary of the invention

[0003] The present invention aims at the deficiencies in the prior art and provides a novel food packaging machine. The food packaging machine has a simple structure, low cost, convenient maintenance, small size and convenient use.

[0004] The technical solution of the present invention to solve the above technical problems is as follows: a new type of food packaging machine, the food packaging machine includes a machine body and a control system, the upper end of the machine body is provided with a feed hopper, the inside of the machine body is provided with a first drive motor, a second drive motor, a film roll, a guide roller, a pressure wheel, a heating edge pressing wheel, and a bottom supporting assembly, a heating tube is installed on the bottom supporting assembly, the first drive motor, the second drive motor, the heating edge pressing wheel, and the bottom supporting assembly are all associated with the control system, the lower end of the machine body is provided with a discharge guide port, and the packaging film on the film roll passes through the guide roller, the pressure wheel, the heating edge pressing wheel, the bottom supporting assembly and the discharge guide port in sequence;

[0005] The film roll, guide roller, pressure wheel, heating pressing wheel and bottom supporting assembly are all rotatably connected to the side of the machine body, and rotating wheels are installed on the motor shafts of the first driving motor and the second driving motor. Rotating wheels are installed at the ends of the guide roller, pressure wheel, heating pressing wheel and bottom supporting assembly. A guide wheel is provided on the side of the machine body, and the first driving motor is connected to the guide roller, pressure wheel and guide wheel through a rotating wheel and a belt. The guide roller rotates in opposite directions, and the pressure wheel rotates in opposite directions. The second driving motor is connected to the bottom supporting assembly and the guide wheel through a rotating wheel and a belt. The second driving motor is a bidirectional rotating motor, and the bottom supporting assembly rotates in opposite directions. The second driving motor controls the opening and closing of the bottom supporting assembly. There is a double-layer belt on the rotating wheel at the end of the pressure wheel, and the pressure wheel is connected to the heating pressing wheel through a rotating wheel and a belt.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows:

[0007] Furthermore, a punching assembly is provided inside the machine body, and the punching assembly is rotatably connected to the side of the machine body. The punching assembly includes a punching roller and a rotating roller. The punching roller is provided with a plurality of punching heads, and the ends of the punching roller and the rotating roller are provided with rotating wheels. The first driving motor is connected to the guide roller, the pressure wheel, the guide wheel, the punching roller and the rotating roller through a rotating wheel and a belt, and the punching roller and the rotating roller rotate in opposite directions.

[0008] The punching assembly can punch holes on the side of the packaging film to facilitate the transmission of the packaged food in the automatic cooking device, thereby making the packaged food more suitable for use in the automatic cooking device.

[0009] Furthermore, a first electromagnetic lock is installed on the side of the machine body, and the first electromagnetic lock is associated with the control system. The lock core of the first electromagnetic lock can move up and down. The first electromagnetic lock is located below the heated pressing wheel, and the heated pressing wheel is located below the pressure wheel.

A connecting plate is provided between the pressure wheel and the heated pressing wheel, and a connecting rod is fixedly connected to the bottom of the connecting plate, and the other end of the connecting rod is rotatably connected to the lock core of the first electromagnetic lock.

[0010] When the lock core of the first electromagnetic lock moves, the connecting rod pushes the heating pressing wheel to move in the slide groove, thereby controlling the opening and closing of the heating pressing wheel. When the heating pressing wheel heats the packaging film for too long, the first electromagnetic lock can separate the two heating pressing wheels to avoid excessive heating of the packaging film by the heating pressing wheel.

[0011] Furthermore, a second electromagnetic lock is installed on the side of the machine body, and the second electromagnetic lock is associated with the control system. The second electromagnetic lock is located between the two heating tubes. The lock core of the second electromagnetic lock is wedge-shaped.

The lock core of the second electromagnetic lock can be inserted between the two heating tubes to separate the two heating tubes, thereby preventing the heating tubes from heating the packaging film for too long.

[0012] Furthermore, the food packaging machine comprises an air filling tube, the end of which is located below the feed hopper. During the packaging process, the air filling tube can fill gas into the food packaging film, thereby preventing the packaged food from being squeezed.

[0013] Furthermore, a side groove is provided on the side of the machine body, and the two ends of the roll film are placed in the side groove to facilitate the installation and replacement of the roll film.

[0014] Furthermore, an outer cover shell is provided on the side of the body, the body is connected to a bracket, and a material box is provided below the body, and the packaged food is stacked in the material box.

[0016] Furthermore, a pressing roller is provided in the machine body, the pressing roller is rotatably connected to the side of the machine body, the pressing roller is located above the guide roller, and the packaging film on the roll film passes between the pressing roller and the guide roller. The setting of the pressing roller makes the packaging film more regular during the transportation process, which is more conducive to the transmission of the packaging film.

[0017] The present invention also discloses a method for using the food packaging machine, comprising the following steps:

[0018] 1) Install the roll film for packaging food into the machine body;

[0019] 2) Under the control of the control system, the first driving motor is turned on, and the packaging film on the roll film passes through the guide roller, the pressing wheel, the heating pressing wheel and the bottom supporting assembly in sequence. The heating pressing wheel heats both sides of the packaging film, so that both ends of the packaging film are closed;

[0020] 3) placing the food to be packaged in the feed hopper, and under the control of the control system, the second drive motor controls the bottom support assembly to be in a closed state, and the heating tube heats the lower end of the packaging film, thereby closing the lower end of the packaging film;

[0021] 4) Under the control of the control system, the second drive motor controls the bottom supporting assembly to be in an open state, and the first drive motor drives the guide roller, the pressing wheel and the heating pressing wheel to rotate, thereby causing the packaging film to move downward;

[0022] 5) After the packaging film moves downward to a set length, under the control of the control system, the second drive motor controls the bottom support assembly to close, and the heating tube heats the upper end of the packaging film, thereby closing the upper end of the packaging film and completing the packaging of the food.
