Description

Technical Field

[0001] The utility model relates to the technical field of film sealing devices, in particular to a film sealing device for frozen pre-prepared vegetable packaging bags. Background Art

[0002] Frozen pre-prepared meals refer to convenient dishes that have been pre-processed, such as cleaning, cutting, seasoning, etc., and then preserved using freezing technology. After purchase, consumers only need to simply heat or cook them before eating, saving the tedious preparation process of buying vegetables, washing vegetables, and cutting vegetables. In the frozen state, the loss of water will affect the taste and quality of the pre-prepared meals. The sealing film can effectively prevent the evaporation of water and maintain the fresh taste of the food, so it is packaged using a packaging bag sealing device.

[0003] Traditional bag sealing systems typically consist of a heating element, a pressing element, a conveying mechanism, and a control unit. The heating element, typically a heating strip or plate, generates heat through electrical current, melting the plastic film at the bag's seal. The pressing element, typically a roller or platen, heats the seal to create a tight seal. The conveying mechanism, typically a conveyor belt or chain drive, transports the bag to the heating and pressing area. The control unit adjusts parameters such as heating temperature, conveying speed, and pressing force.

[0004] Traditional bag-sealing systems often feature integrated heating and pressing components, tightly integrated with molds of specific sizes. This design fails to accommodate the rapid replacement of molds required for different bag sizes. This complex, time-consuming, and labor-intensive process requires disassembly of numerous fixed components when replacing molds. This difficulty leads to low production efficiency, and the time consuming mold replacement process for producing bags of varying sizes hinders overall production schedules. Furthermore, frequent disassembly and installation can damage the equipment and reduce its lifespan. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a frozen pre-prepared food packaging bag sealing device, which aims to improve the problem of low production efficiency caused by the difficulty of replacing the mold in the traditional packaging bag sealing device.

[0006] In order to achieve the above-mentioned object, the utility model adopts the following technical solution: a film sealing device for packaging bags of frozen pre-prepared dishes, comprising a machine body, a film laminating platform provided on the top of the machine body, a mold changing assembly provided inside the film laminating platform, the mold changing assembly being used to replace the mold, a feeding assembly provided inside the machine body, the feeding assembly being used to supply the pre-prepared dishes;

[0007] The mold changing assembly includes a support, and multiple supports are fixedly connected to the inside of the laminating table. The tops of the supports are fixedly connected to fixed shafts, the outer walls of the fixed shafts are rotatably connected to connecting frames, the side walls of the connecting frames are fixedly connected to side tables, the side walls of the side tables are rotatably connected to side plates, the side walls of the side plates are fixedly connected to the closing platform, the inside of the laminating table is fixedly connected to a cylinder, the output end of the cylinder is fixedly connected to a push frame, and the push frame is slidably connected to the inside of the connecting frame.

[0008] Furthermore, the loading assembly includes a conveyor belt, and the conveyor belt is arranged inside the machine body.

[0009] Furthermore, a fixing platform is fixedly connected to the interior of the machine body, and a transmission column is rotatably connected to the upper surface of the fixing platform.

[0010] Furthermore, a rotating wheel is fixedly connected to the outer wall of the transmission column, and a groove is provided inside the rotating wheel.

[0011] Furthermore, a motor is fixedly connected inside the fixing platform, and a transmission disk is fixedly connected to an output end of the motor.

[0012] Furthermore, a cam is fixedly connected to the upper surface of the transmission disc, and a connecting shaft is fixedly connected to the upper surface of the transmission disc.

[0013] Furthermore, the connecting shaft is slidably connected to the inside of the groove, a plurality of circular grooves are opened inside the transmission column and are slidably connected to the inside of the circular groove, and a tray is fixedly connected to the top of the rotating wheel.

[0014] The utility model has the following beneficial effects:

[0015] 1. In this utility model, the cylinder first applies a pulling force to the push frame, which eventually causes the side platform to change direction and further drives the side panels of its side walls to move. At this time, the combination of multiple side panels and side walls changes the opening angle, thereby fixing or releasing the mold and achieving the effect of convenient mold replacement. When it is necessary to produce frozen pre-prepared food packaging bags of different specifications or types, the convenient mold replacement can complete the mold switching in a short time, allowing the equipment to quickly start the new production task. There is no need for complicated disassembly and installation processes, which greatly reduces equipment downtime and improves production efficiency.

[0016] 2. In this utility model, the motor outputs a rotational force to the transmission disc, driving the transmission disc to rotate. Ultimately, the force is applied to the rotating wheel, which rotates along the outer wall of the transmission column. The tray on top of the rotating wheel rotates periodically, feeding the pre-prepared dishes in a cyclical manner for film coating. Orderly loading ensures that the packaging bags can enter the film sealing device continuously and stably, avoiding equipment downtime caused by unsmooth loading. The equipment can operate continuously without frequent adjustments and waiting, thereby greatly improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1 - Figure 2 The present invention provides an embodiment of a film sealing device for frozen pre-prepared food packaging bags, comprising a body 1, a film laminating platform 2 provided on the top of the body 1, the film laminating platform 2 presses down the pre-prepared food through a hydraulic structure to laminarize the pre-prepared food, a die changing assembly provided inside the film laminating platform 2, the die changing assembly being used to replace the die, a feeding assembly provided inside the body 1, the feeding assembly being used to supply the pre-prepared food;

[0024] The mold changing assembly includes a support platform 3, and multiple support platforms 3 are fixedly connected to the inside of the coating table 2. The support platform 3 provides support for the fixed shaft 4. The top of the support platform 3 is fixedly connected to the fixed shaft 4, and the fixed shaft 4 fixes the rotation axis of the connecting frame 5. The outer wall of the fixed shaft 4 is rotatably connected to the connecting frame 5. The side walls of the connecting frame 5 are fixedly connected to the side platform 6. The side platform 6 moves with the rotation of the connecting frame 5. The side wall of the side platform 6 is rotatably connected to the side plate 7. The side wall of the side plate 7 is fixedly connected to the closing platform 8. The engaging state of the closing platform 8 determines the release and fixation of the mold. The inside of the coating table 2 is fixedly connected to the cylinder 9, and the output end of the cylinder 9 is fixedly connected to the push frame 10. The push frame 10 is slidably connected to the inside of the connecting frame 5.

[0025] Specifically, first, when the mold of this device needs to be replaced, the cylinder 9 can be started. The cylinder 9 will first output a pulling force to the push frame 10. The push frame 10 will be displaced after receiving the driving force. The two sides of the push frame 10 will move in multiple connecting frames 5 and apply pulling force to the connecting frame 5. After being subjected to the force, the connecting frame 5 will further rotate on the outer wall of the fixed shaft 4 and change its own inclination angle. During the rotation of the connecting frame 5, the side platform 6 of its side wall will follow the change in direction and further drive the side plate 7 of its side wall to displace. At this time, the closing platform 8 of the side walls of multiple side plates 7 will change the opening angle, thereby fixing or releasing the mold and achieving the effect of convenient mold replacement. When it is necessary to produce frozen pre-prepared food packaging bags of different specifications or types, the convenient mold replacement can complete the mold switching in a relatively short time, so that the equipment can be quickly put into new production tasks without the need for complicated disassembly and installation processes, which greatly reduces equipment downtime to a certain extent and improves production efficiency.

[0026] Reference Figure 3 The loading component includes a conveyor belt 11, which is used to transport materials. The conveyor belt 11 is arranged inside the machine body 1, and is fixedly connected to a fixed platform 12 inside the machine body 1. The upper surface of the fixed platform 12 is rotatably connected to a transmission column 17. The transmission column 17 ensures the rotation of the runner 18, and the outer wall of the transmission column 17 is fixedly connected to the runner 18. A groove 19 is provided inside the runner 18. The fixed platform 12 is fixedly connected to the motor 13, and the output end of the motor 13 is fixedly connected to a transmission disk 14. The transmission disk 14 rotates after receiving the driving force, and the upper surface of the transmission disk 14 is fixedly connected to a concave wheel 15. The upper surface of the transmission disk 14 is fixedly connected to a connecting shaft 16, and the connecting shaft 16 is slidably connected to the inside of the groove 19. The sliding of the connecting shaft 16 in the groove 19 will drive the runner 18 to rotate. A plurality of circular grooves 20 are provided inside the transmission column 17, and the concave wheel 15 is slidably connected to the inside of the circular groove 20. A tray 21 is fixedly connected to the top of the runner 18, and the tray 21 rotates with the runner 18.

[0027] Specifically, when the pre-prepared dishes need to be coated and packaged, the pre-prepared dishes are placed on the surface of the conveyor belt 11 for transmission and enter the surface of the tray 21. At this time, the motor 13 will output a rotational force to the transmission disc 14, driving the transmission disc 14 to rotate. During the rotation of the transmission disc 14, the concave wheel 15 on its surface will slide inside the circular groove 20. Then, the connecting shaft 16 will slide in the groove 19 inside the rotating wheel 18, further causing the rotating wheel 18 to be subjected to force, thereby mobilizing the rotating wheel 18 to rotate on the outer wall of the transmission column 17, and the tray 21 on the top of the rotating wheel 18 will rotate periodically, cyclically feeding the pre-prepared dishes for coating operations. This orderly loading method can ensure that the packaging bags can enter the film sealing device continuously and stably, avoiding equipment shutdown caused by unsmooth loading. In this way, the equipment can continue to operate without frequent adjustments and waiting, which greatly improves production efficiency to a certain extent.

[0028] Working principle: First, when the mold of this device needs to be replaced, start the cylinder 9. The cylinder 9 first outputs a pulling force to the push frame 10. The push frame 10 will be displaced after receiving the driving force. The two sides of the push frame 10 will move in multiple connecting frames 5 and apply pulling force to it. After receiving the force, the connecting frame 5 will further rotate on the outer wall of the fixed shaft 4 and change its own inclination angle. During the rotation of the connecting frame 5, the side platform 6 of its side wall will follow the change in direction and further drive the side plate 7 of its side wall to displace. At this time, the closing platform 8 of the side walls of multiple side plates 7 will change the opening angle, thereby fixing or releasing the mold, achieving the effect of convenient mold replacement. When it is necessary to produce frozen pre-prepared food packaging bags of different specifications or types, the convenient mold replacement can complete the mold switching in a short time, so that the equipment can be quickly put into new production tasks. There is no need for complicated disassembly and installation processes, which greatly reduces equipment downtime and improves production efficiency. When the pre-prepared dishes need to be coated and packaged, they are placed on the surface of the conveyor belt 11 for transmission and enter the surface of the tray 21. At this time, the motor 13 will output a rotational force to the transmission disk 14 to drive the transmission disk 14 to rotate. During the rotation of the transmission disk 14, the concave wheel 15 on its surface will slide inside the circular groove 20, and then the connecting shaft 16 will slide in the groove 19 inside the rotating wheel 18, further causing the rotating wheel 18 to be stressed and mobilized to rotate on the outer wall of the transmission column 17. The tray 21 on the top of the rotating wheel 18 will rotate periodically, and the pre-prepared dishes are cyclically fed for coating. The orderly loading ensures that the packaging bags can continuously and stably enter the film sealing device, avoiding equipment downtime due to unsmooth loading. The equipment can operate continuously without frequent adjustments and waiting, thereby greatly improving production efficiency.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
