Description

Technical Field

[0001] This utility model relates to the field of sterilization technology, and in particular to a food packaging sterilization device. Background Technology

[0002] In the food packaging industry, steam sterilization is a key pretreatment process to extend product shelf life and avoid food safety risks caused by microbial contamination. Currently, various steam sterilization devices for packaged foods have emerged in the industry. For example, Chinese patent CN222603626U uses a sterilization chamber, a sliding rack, and a screw drive structure to achieve steam contact sterilization of food, thus improving the convenience of sterilization to some extent.

[0003] However, the aforementioned device has the following drawbacks: its sterilization process requires intermittent execution of steps such as flipping, opening and closing the sliding plate, and moving the connecting rod, making continuous operation impossible; furthermore, its single-batch processing capacity is limited, it relies on manual feeding and unloading, has long idle waiting times, and processes few batches per unit time, making it difficult to adapt to the needs of industrialized mass production. Therefore, further improvements are needed. To this end, we propose a food packaging sterilization device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a food packaging sterilization device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a food packaging sterilization device, comprising a frame and an industrial control integrated computer fixedly installed on one side of the outer wall of the frame. Both inner walls of the frame are equipped with chain-type transmission components, and the two chain-type transmission components are jointly installed with two connecting shafts. A reduction motor is fixedly connected to one side of the outer surface of the frame, and the drive shaft of the reduction motor passes through the frame and is fixedly connected to the adjacent connecting shaft.

[0006] Both of the chain-type transmission components are fixedly connected to a number of connectors. The connectors are grouped in pairs. The two connectors in the same group are fixedly connected to a top sealing frame and a bottom sealing frame. The top sealing frames and the bottom sealing frames are jointly and slidably connected to a wire basket. The wire baskets and the adjacent bottom sealing frames are jointly installed with two elastic reset members.

[0007] The lower sealing housing is fixedly connected to the inner walls on both sides of the frame, and the lower sealing housing is sealed and fitted to the bottom of the adjacent bottom sealing frame. A steam assembly is installed between the lower sealing housing and the frame.

[0008] An upper sealing shell is provided directly above the lower sealing shell, and the upper sealing shell is sealed and fitted to the top of the adjacent top sealing frame. Support frames are fixedly connected to both sides of the outer surface of the upper sealing shell, and the support frames are fixedly connected to the top of the frame. A cylinder is fixedly connected to one side of the outer surface of a single support frame, and the movable end of the cylinder passes through the support frame and matches the adjacent basket.

[0009] Furthermore, both of the chain-type transmission components include two sprockets, which are fixedly sleeved on the connecting shaft. The outer surfaces of the two sprockets are engaged with the chain body, and the chain body is fixedly connected to several adjacent connecting parts. Through the meshing transmission between the sprockets and the chain body, the synchronous and smooth cyclic movement of multiple basket units is realized, providing a stable and reliable power foundation for continuous production.

[0010] Furthermore, both ends of the two connecting shafts are rotatably connected to the frame, and the frame provides support for the connecting shafts, which facilitates their installation.

[0011] Furthermore, each of the aforementioned elastic reset components includes a mounting groove, which is formed on one inner wall of the bottom sealing frame. Guide rods are fixedly connected to both inner walls of the mounting groove. A slider is slidably sleeved on the outer surface of the guide rod, and the slider is fixedly connected to the basket. A spring is fixedly connected to the end of the slider opposite to the cylinder, and the spring is sleeved on the outer surface of the guide rod and fixedly connected to the mounting groove. This elastic reset component not only provides a reliable lateral sliding connection for the basket, but its core function is to cooperate with the cylinder to convert the linear thrust of the cylinder into efficient and controllable horizontal reciprocating vibration of the basket, forcing the food packaging inside the basket to produce micro-displacement, effectively breaking the vapor boundary layer.

[0012] Furthermore, the steam assembly includes an electrically controlled valve, which is fixedly connected to one side of the outer wall of the frame. One of the ports of the electrically controlled valve is fixedly connected to a bend, which extends through the frame into the interior of the lower sealing housing and is fixedly connected to the lower sealing housing. A steam plate is fixedly connected to the top of the bend, and multiple steam nozzles are fixedly connected to the top of the steam plate. The steam plate and the steam nozzles cooperate to spray steam evenly and dispersedly into the sterilization chamber.

[0013] Furthermore, the top of the upper sealing housing is fixedly connected to an exhaust pipe to facilitate the discharge of steam.

[0014] The beneficial effects of this utility model are:

[0015] In use, this invention, through the coordinated design of the chain-driven transmission assembly, the top sealing frame, the bottom sealing frame, and the wire basket, along with the upper and lower sealing shells, successfully constructs a continuously operating dynamic sterilization system, effectively overcoming the shortcomings of low efficiency in intermittent operation in the prior art. This device enables food packaging to be sealed and sterilized during transportation without stopping for loading and unloading, significantly reducing idle waiting time. At the same time, the overall automated operation reduces reliance on manual operation, greatly improving the processing capacity per unit time, perfectly adapting to the continuous operation requirements of industrial mass production.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4 As shown, a food packaging sterilization device is disclosed, including a frame 1 and an industrial control integrated computer 2 fixedly installed on the outer wall of one side of the frame 1. The frame 1 serves as the main support structure of the entire device, bearing and connecting all other components. The industrial control integrated computer 2 is the "brain" of the device, used to set process parameters such as sterilization temperature, time, and vibration frequency. It is electrically connected to the geared motor 8, electric control valve 9, and cylinder 3, which facilitates centralized control of the coordinated operation of the actuators such as the geared motor 8, electric control valve 9, and cylinder 3.

[0025] Both inner walls of the frame 1 are equipped with chain-type transmission components. The two chain-type transmission components share two connecting shafts 22. Each chain-type transmission component includes two sprockets 23, which are fixedly sleeved on the connecting shafts 22. The outer surfaces of the two sprockets 23 mesh with the chain body 21. The chain body 21 needs to be tensioned and lubricated regularly to maintain optimal transmission performance and extend its service life. Both ends of the two connecting shafts 22 are rotatably connected to the frame 1. The connecting shafts 22 and the frame 1 are rotatably connected by bearing seats. The bearing seat is fixedly connected to the frame 1. The inner ring of the bearing inside the bearing seat is fixedly sleeved on the outer surface of the connecting shaft 22. A geared motor 8 is fixedly connected to one side of the outer surface of the frame 1. The drive shaft of the geared motor 8 passes through the frame 1 and is fixedly connected to the adjacent connecting shaft 22. The geared motor 8 is selected from the Nord Universal series. Its start, stop and speed are controlled by the industrial control computer 2 to match different production cycles.

[0026] Both chain-type transmission components are fixedly connected with several connectors 10, and the chain body 21 is fixedly connected to several adjacent connectors 10. The connectors 10 are in pairs, and the two connectors 10 in the same group are fixedly connected to the top sealing frame 16 and the bottom sealing frame 14. The connectors 10 serve as the connecting bridge between the chain body 21 and the top sealing frame 16 and the bottom sealing frame 14, and are made of SS304 stainless steel plate bent into shape.

[0027] A mesh basket 7 is slidably connected between several top sealing frames 16 and bottom sealing frames 14. The mesh basket 7 is made of stainless steel and has mesh holes at the bottom to facilitate the passage of steam. Each mesh basket 7 and the adjacent bottom sealing frame 14 are equipped with two elastic reset members. Each elastic reset member includes a mounting groove 17, which is located on one inner wall of the bottom sealing frame 14. Guide rods 20 are fixedly connected to the inner walls on both sides of the mounting groove 17. A slider 18 is slidably sleeved on the outer surface of the guide rod 20 and is fixedly connected to the mesh basket 7. A spring 19 is fixedly connected to the end of the slider 18 that is opposite to the cylinder 3. The spring 19 is sleeved on the outer surface of the guide rod 20 and fixedly connected to the mounting groove 17. The spring 19 is made of stainless steel spring wire.

[0028] The inner walls on both sides of the frame 1 are fixedly connected to a lower sealing housing 15, and the lower sealing housing 15 is sealed and fitted to the bottom of the adjacent bottom sealing frame 14. A steam assembly is installed between the lower sealing housing 15 and the frame 1. The steam assembly includes an electric control valve 9, and the electric control valve 9 is fixedly connected to the outer wall on one side of the frame 1. One of the ports of the electric control valve 9 is fixedly connected to a bend 13, and the bend 13 extends through the frame 1 to the interior of the lower sealing housing 15 and is fixedly connected to the lower sealing housing 15. A steam plate 11 is fixedly connected to the top of the bend 13, and multiple steam nozzles 12 are fixedly connected to the top of the steam plate 11. The electric control valve 9 is a DN25 electric two-position two-way shut-off valve. The inlet end of the electric control valve 9 is connected to the factory's steam main or steam boiler through a pipeline as a steam source.

[0029] An upper sealing shell 6 is located directly above the lower sealing shell 15, and the upper sealing shell 6 is sealed and fitted to the top of the adjacent top sealing frame 16. An exhaust pipe 5 is fixedly connected to the top of the upper sealing shell 6. The outlet end of the exhaust pipe 5 is usually connected to the exhaust system of the workshop roof or connected to the condensation recovery device. An electric valve in the prior art is set at the connection point and electrically connected to the industrial control all-in-one computer 2 to facilitate the opening and closing of the exhaust pipe 5, so as to facilitate the safe and orderly discharge of steam and energy recovery, while maintaining a comfortable workshop environment. Support frames 4 are fixedly connected to both sides of the outer surface of the upper sealing shell 6, and the support frames 4 are fixedly connected to the top of the frame 1. A cylinder 3 is fixedly connected to one side of the outer surface of a single support frame 4, and the movable end of the cylinder 3 passes through the support frame 4 and matches the adjacent wire basket 7. The top and bottom of the top sealing frame 16 and the top and bottom of the bottom sealing frame 14 are fixedly connected to the spiral silicone rubber sealing strip. The silicone rubber sealing strip is resistant to high temperature, has good elasticity, and can achieve reliable dynamic sealing.

[0030] Working principle: The geared motor 8 intermittently drives the connecting shaft 22 to rotate, which in turn drives the sprocket 23 to rotate, thereby causing the chain body 21 to move in a cycle. The sealed conveying unit (including the top sealing frame 16, the bottom sealing frame 14, and the wire basket 7) which is fixed to the chain body 21 by the connector 10 moves accordingly.

[0031] At the feeding end of the device, the operator or automated equipment places the food packaging to be sterilized into the mesh basket 7.

[0032] The carrying unit moves with the chain body 21 to the sterilization area between the upper sealing housing 6 and the lower sealing housing 15. In this position, the top of the top sealing frame 16 slides and seals against the bottom of the upper sealing housing 6, and the bottom of the bottom sealing frame 14 slides and seals against the top of the lower sealing housing 15, together forming a movable, essentially sealed sterilization chamber.

[0033] The industrial control unit 2 opens the electric control valve 9, and high-temperature steam enters the steam pan 11 through the bend pipe 13, and is finally sprayed upward by multiple steam nozzles 12, filling the sealed chamber.

[0034] Simultaneously, the industrial control computer 2 controls the cylinder 3 to start working. The movable end of the cylinder 3 extends horizontally, directly pushing the mesh basket 7. The thrust of the cylinder 3 causes the mesh basket 7 to overcome the elastic force of the spring 19, driving the slider 18 to slide to one side on the guide rod 20. When the cylinder 3 retracts, the elastic potential energy stored in the spring 19 is released, pushing the slider 18 and causing the mesh basket 7 to slide back to its original position along the guide rod 20. By controlling the cylinder 3 to reciprocate at a specific frequency and stroke, the industrial control computer 2 can drive the mesh basket 7 and the food packaging inside it to continuously and stably reciprocate on a horizontal plane. This vibration causes the food packaging to continuously tumble and shift in the high-temperature steam environment, preventing the packaging from covering each other or sticking together, ensuring that the steam can contact all surfaces, thereby greatly improving the uniformity and thoroughness of sterilization.

[0035] After the preset sterilization and vibration time is completed, the electric control valve 9 closes, steam is discharged through the exhaust pipe 5, the cylinder 3 stops working, and the basket 7 remains stationary in the center position under the action of the spring 19. Subsequently, the unit moves out of the sterilization area along with the chain body 21.

[0036] The unit moves to the discharge end, and the sterilized food packaging is removed.

[0037] The empty unit continues to run with the chain body 21, returns to the feed end, and begins the next work cycle.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
