Description

Technical Field

[0001] The utility model relates to the technical field related to film sealing machines, in particular to a bowl cover film sealing machine with stable use. Background Art

[0002] Pre-prepared meals are products that are made by pre-processing edible raw materials into semi-finished or finished products. They have the characteristics of long shelf life and convenience of consumption. Pre-prepared meals are divided into four categories: ready-to-eat food, ready-to-heat food, ready-to-cook food, and ready-to-mix food. Now more and more consumers prefer to use pre-prepared meals as daily food. The production process of pre-prepared meals includes raw material processing, fresh-keeping packaging, storage, transportation and other processes. In the packaging process of pre-prepared meals, a film sealing machine is required to seal the lid of the pre-prepared meal bowl.

[0003] Among them, the "A bowl lid film sealing machine with stable use" disclosed in the authorization announcement number "CN221624052U" includes a positioning frame, and the inner walls on both sides of the positioning frame are equidistantly installed with positioning gear rollers, and the number of positioning gear rollers is four, and a chain is installed on the outside of each two positioning gear rollers in meshing engagement, and the outer walls on both sides of the positioning frame are fixed with a first motor, and the outer sides of the output shafts of the two first motors are fixed with gears on one end of two of the positioning gear rollers, and each two of the gears are in meshing connection, and positioning plates are fixed on the outside of the two chains at equal intervals. The bowl lid film sealing machine with stable use provided by the utility model is provided by the user placing the pre-made vegetable bowl inside the positioning plate, and then starting the first motor. After the first motor is started, the meshing transmission between the gears drives the chain to rotate, and the positioning plate is driven by the chain to move, thereby moving it to the bottom of the top frame, which is convenient for the large-scale transportation and film sealing of the pre-made vegetable bowl lids;

[0004] However, it also has certain disadvantages. That is, when the dish is placed in the bowl, the center part will protrude from the mouth of the bowl in most cases. Secondly, the heating and sealing on the top heating plate can easily produce harmful substances and contaminate the dish.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the utility model provides a stable bowl cover sealing machine. The utility model solves the problem in related solutions that the heating plate is heat-sealed to the edge of the bowl, and the heating and sealing of the plastic wrap easily produces harmful substances that contaminate the dishes through the setting of the main body component.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] The lifting mechanism is a lifting mechanism that lifts up and down of described lifting mechanism, and the lifting mechanism is lifted up and down, and lifts up and down of described lifting mechanism.

[0009] Preferably, there are several placement trays.

[0010] Preferably, the linear modules, fixing plates, film sealing components and motors on the same side are grouped into two groups, with two groups in total being arranged in mirror images.

[0011] Preferably, the two linear modules are controlled by different numerical control units.

[0012] Preferably, the motor 1 and the motor 2 are both servo motors.

[0013] Preferably, a rotating roller is fixed on one side of the chain conveyor.

[0014] Compared with the prior art, the present invention provides a bowl cover film sealing machine with stable use, which has the following beneficial effects:

[0015] 1. The utility model has a main body component. When in use, the plastic wrap is installed on the installation roller and the dishes to be sealed are placed in the center of the placement plate. The dishes will first move under the U-shaped hot plate to heat-cut the plastic wrap on both sides of the dishes. Then the chain conveyor continues to move to move the sealed dishes under the film sealing component. When the motor rotates, the film sealing part rotates to wrap the outer plastic wrap around the side of the bowl and seal it by the winding method. This solves the problem in related solutions that the heating hot plate is heat-sealed on the edge of the bowl, and the heat-sealed plastic wrap easily produces harmful substances that contaminate the dishes.

[0016] 2. The utility model is equipped with a sealing component. Since the linear module and the second motor can always adjust the contact distance between the sealing component and the bowl mouth, it can be used for dishes of different shapes and sizes, solving the problem that the related solutions can only seal the film on annular plates and have poor versatility.

[0026] This device is used to seal cling film for semi-finished dishes. When in use, the cling film is installed on the installation roller 14, and then the dish to be sealed is placed on the center of the placement plate 12, and then the chain conveyor 11 is started. One end of the cling film is placed on the side of the placement plate 12 with human assistance. When the chain conveyor 11 is running, it drives the dish to move. It will first move to the bottom of the U-shaped ironing plate 18, and then under the action of the hydraulic telescopic rod 17, the U-shaped ironing plate 18 is pressed down to perform thermal cutting on the cling film on both sides of the dish. The contact point of the U-shaped ironing plate 18 is on the side plate 13, and the harmful substances generated by the hot melting of the cling film will not contact the dish. Then the chain conveyor 11 continues to move, so that the sealed dish moves to the bottom of the sealing assembly 2, and the linear module 24 drives the sealing part 26 to move, adjusts its distance from the dish bowl, and then the motor 22 rotates to drive the sealing part 26 to rotate, wrapping the outer cling film to the side of the bowl, and finally completing the sealing.

[0029] Furthermore, the linear module 24, fixed plate 25, film sealing component 26 and motor 27 on the same side are grouped together, with two groups in total, and the two groups are mirror-imaged. The two film sealing components 26 operate synchronously to seal the film, which can improve the sealing efficiency.

[0030] Furthermore, the two linear modules 24 are controlled by different numerical control units. The two linear modules 24 are controlled separately, which can better seal the plates that are neither axisymmetric nor centrally symmetrical.

[0031] Furthermore, the motor 1 22 and the motor 2 27 are both servo motors, which can accurately control the rotation and stop, thereby improving the film sealing quality.

[0032] Furthermore, a rotating roller 15 is fixed to one side of the chain conveyor 11, and the rotating roller 15 lowers the height of the plastic wrap so that it is just above the dishes.

[0033] Working principle: This device is used to seal cling film for semi-finished dishes. When in use, the cling film is installed on the installation roller 14, and then the dish to be sealed is placed on the center of the placement plate 12, and then the chain conveyor 11 is started. One end of the cling film is placed on the side of the placement plate 12 with human assistance. When the chain conveyor 11 is running, it drives the dish to move. It will first move to the bottom of the U-shaped ironing plate 18, and then under the action of the hydraulic telescopic rod 17, the U-shaped ironing plate 18 is pressed down to perform thermal cutting on the cling film on both sides of the dish. The contact point of the U-shaped ironing plate 18 is on the side plate 13, and the harmful substances generated by the hot melting of the cling film will not contact the dish. Then the chain conveyor 11 continues to move, so that the sealed dish moves to the bottom of the sealing assembly 2, and the linear module 24 drives the sealing part 26 to move, adjusts its distance from the dish bowl, and then the motor 22 rotates to drive the sealing part 26 to rotate, wrapping the outer cling film to the side of the bowl, and finally completing the sealing.
