Description

Technical Field

[0001] This utility model belongs to the field of container packaging technology, specifically relating to sterilization packaging equipment for disposable containers. Background Technology

[0002] Disposable paper cups, plastic cups, fast food containers, yogurt cups, ice cream cups, sauce cups, self-heating food containers, fresh food packaging boxes, takeaway soup / porridge buckets, baking / dessert containers, and other similar containers (collectively referred to as "disposable containers") generally do not undergo sterilization during the packaging process. This can easily lead to bacterial residue, shortened shelf life, and health hazards. Disposable containers come into direct contact with drinking water, beverages, and food; if microbial contamination exists, it can directly endanger the health of users.

[0003] Oversights in multiple stages of the disposable container production environment can become entry points for microbial contamination. These can be broadly categorized into five main factors: air, equipment, personnel, raw materials, and cleaning and disinfection.

[0004] 1. Air environment factors Airborne microorganisms are the most easily overlooked source of pollution, and they will settle directly onto the surface of paper cups.

[0005] Air cleanliness is not up to standard: The production workshop has not carried out air purification treatment, or the clean area level is not high enough (such as not reaching Class 10,000 or Class 100,000), and bacteria and mold spores in the air will spread with the airflow.

[0006] Ventilation system problems: If the vents are not equipped with filters, the filters are not replaced for a long time, or the airflow direction is unreasonable (such as flowing from the contaminated area to the clean area), microorganisms will be carried into the core production area.

[0007] Excessive dust in the workshop: Dust is a "carrier" for microorganisms. If the paper dust generated during paper cutting and paper cup forming is not cleaned up in time, it will attach to microorganisms and settle on the products.

[0008] 2. Production equipment factors The equipment is a critical link that comes into direct contact with paper cups, and inadequate surface cleaning can lead to continuous contamination.

[0009] Residual dirt on equipment surfaces: If paper fibers, oil stains, or debris from previous batches remain in the gaps of equipment such as conveyor belts, molds, and packaging machines, bacteria will grow and transfer to newly produced paper cups.

[0010] Untimely equipment maintenance: After prolonged operation, the seals may age, parts may rust, or all contact points (such as corners and interfaces) may not be covered during cleaning and disinfection, creating breeding grounds for microorganisms.

[0011] Cooling water / lubricant contamination: Some equipment requires the use of cooling water or lubricant. If these media themselves have excessive microorganisms, or if a leak occurs and comes into contact with the paper cup, it will directly cause contamination.

[0012] 3. Operator factors People are dynamic sources of pollution in the production environment, and their hygiene habits directly affect product safety.

[0013] Inadequate hand cleaning: If operators do not wash and disinfect their hands as required, or if their gloves are damaged or not replaced in time, bacteria on their hands (such as E. coli and Staphylococcus aureus) can be transferred to the paper cups through contact.

[0014] Inadequate personal protective equipment: Not wearing clean work clothes, caps, and masks allows microorganisms from hair, dander, and clothing to detach and contaminate products; eating and smoking in the workshop can also introduce exogenous microorganisms.

[0015] Improper personnel movement control: Non-production personnel may enter the clean area at will, or production personnel may enter the clean area directly from contaminated areas (such as raw material warehouses or restrooms), which may bring external microorganisms into the core production process.

[0016] 4. Raw material and auxiliary material factors If the raw materials themselves carry bacteria, it is difficult to completely remove them during subsequent processing, which will become a source of pollution.

[0017] Excessive microorganisms in the base paper / PE film: If the base paper of the paper cup (such as food-grade white cardboard) or the PE film on the inner wall gets damp during production, storage, and transportation (such as excessive humidity in the warehouse), mold will grow; damaged packaging can also lead to microbial invasion.

[0018] Adhesive / Ink Contamination: Some paper cups require adhesives for molding or inks for external printing. If these auxiliary materials themselves fail to meet microbial standards or are contaminated during use, it will indirectly affect the hygiene of the paper cups.

[0019] 5. Cleaning and disinfection factors Improper cleaning and disinfection procedures can lead to the continuous accumulation of microorganisms in the production environment.

[0020] Incomplete cleaning: If only the surface of the workshop floor, walls, countertops, and auxiliary tools such as turnover baskets and pallets are cleaned without thoroughly cleaning the gaps and corners, microorganisms will remain and gradually multiply.

[0021] Improper disinfection frequency / method: Disinfection intervals that are too long (such as disinfecting only once a day, which cannot control the rate of microbial reproduction), or the use of insufficient concentration or unsuitable type of disinfectant (such as being ineffective against mold) will result in poor disinfection effects.

[0022] Secondary contamination after disinfection: If disinfected equipment and tools are not dried in time, or if they come into contact with unsterilized cloths or containers, they will be contaminated again by microorganisms.

[0023] During the molding, stacking, and packaging processes, disposable containers easily come into contact with equipment surfaces, operators' hands, and the air, potentially harboring bacteria, mold, and other microorganisms. These microorganisms can multiply during storage, especially in humid environments where the risk of mold growth is extremely high. By omitting the sterilization process, bacteria persist throughout the entire process from production to storage, ultimately reaching the end user. The specific hazards can be summarized in three points: 1. Storage Stage: Accelerated Deterioration and Significantly Shortened Shelf Life. Bacteria carried by containers during packaging (such as E. coli and mold spores from the production environment) will multiply rapidly under suitable temperature and humidity conditions (such as a humid warehouse and a temperature above 25°C). For example, disposable containers may develop mold, plastic cups may develop odors, and the inner walls of fast food boxes may become sticky. The original shelf life of 6 months may be shortened to 2-3 months, directly causing inventory losses.

[0024] 2. Usage Stage: Directly Threatens User Health. These multiplied bacteria can enter the human body through beverages and food that come into contact with the container. If the bacterial count exceeds the standard (e.g., E. coli exceeds the national standard), it may cause gastrointestinal discomfort, such as diarrhea and abdominal pain; if mold grows, it may also produce mycotoxins that are harmful to the human body, which are difficult to completely remove even with heating.

[0025] 3. Brand and compliance risks: Enterprises face double losses. Products without sterilization processes are considered substandard. If discovered by market regulators during random inspections, enterprises will face fines and production suspension for rectification. At the same time, if consumers experience health problems due to product use, it will lead to complaints and negative reviews, seriously damaging brand reputation and even causing market loss.

[0026] In addition, the production efficiency of existing packaging equipment needs to be improved.

[0027] There is an urgent need in the market for a device that can efficiently sterilize containers before packaging. Summary of the Invention

[0028] To address the shortcomings of existing disposable container packaging technology, this invention provides a rotary sterilization device for container packaging that has sterilization function and high production efficiency.

[0029] The rotary sterilization device for container packaging of this utility model adopts the following technical solution.

[0030] The sterilization device includes a sterilization mechanism comprising a rotating shaft, an upper sealing plate, a lower sealing plate, an upper turntable, a lower turntable, a sterilization medium inlet seat, and a sterilization cylinder. The rotating shaft is connected to a motor. The upper sealing plate, upper turntable, lower turntable, and lower sealing plate are sequentially mounted on the rotating shaft from top to bottom. Both the upper and lower sealing plates are connected to a sterilization support. A sterilization cylinder is distributed between the upper and lower turntables, with its two ends connected to the upper and lower turntables respectively. The sterilization medium inlet seat is located on the upper sealing plate. The sterilization cylinder rotates synchronously with the upper and lower turntables.

[0031] The upper sealing plate is provided with a container inlet for docking with the input device, a sterilization medium inlet, mounting holes corresponding to the sterilization medium inlet seat, and adjustment holes for adjusting the gap between the upper turntable and the upper sealing plate. The lower sealing plate is provided with a container outlet for docking with the sealing device. The container outlet and container inlet are staggered (the installation positions of the container inlet and sterilization medium inlet seat on the upper sealing plate are staggered with the installation positions of the container outlet on the lower sealing plate, and are not on the same axis). The purpose is to prevent the upper input port and lower discharge port of the same sterilization cylinder from opening simultaneously, allowing sufficient sterilization time. The number of container inlets and the number of container outlets are the same as the number of input devices.

[0032] Matching annular grooves are provided between the upper turntable and the upper sealing plate, and between the lower turntable and the lower sealing plate. Ball bearings are placed in these annular grooves, allowing the upper turntable and the upper sealing plate, as well as the lower turntable and the lower sealing plate, to rotate relative to each other. Annular grooves accommodating the ball bearings are provided on the opposing surfaces of the upper sealing plate and the upper turntable, and on the opposing surfaces of the lower sealing plate and the lower turntable. The annular grooves on the opposing surfaces of the upper sealing plate and the upper turntable form closed annular tracks, and the annular grooves on the opposing surfaces of the lower sealing plate and the lower turntable form closed annular tracks. The ball bearings rotate within these annular tracks, allowing the upper and lower turntables to rotate flexibly.

[0033] The sterilization cylinders are arranged in a circle around the rotating shaft. The total number and distribution of the container inlets and sterilization medium inlet seats on the upper sealing plate are consistent with the number and distribution of the sterilization cylinders. The container inlets, container outlets, sterilization medium inlets, and the center of the sterilization cylinders are all distributed on concentric circles of equal diameter.

[0034] The sterilization medium inlet seat is provided with a sterilization medium inlet and a sterilization medium outlet. The sterilization medium inlet is connected to an external sterilization medium delivery pipe, and the sterilization medium outlet is connected to the outer cylinder of the sterilization cylinder.

[0035] The sterilization cylinder includes an outer cylinder and an inner cylinder, with the inner cylinder disposed inside the outer cylinder and having a slot on the inner cylinder (to allow the sterilization medium to flow between the inner and outer cylinders).

[0036] The motor drives the upper turntable, sterilization cylinder, and lower turntable to rotate together via a rotating shaft. When the upper inlet of the sterilization cylinder axially overlaps with the sterilization medium inlet seat, a sterilization medium (such as chlorine dioxide gas) is injected into the sterilization cylinder. When the lower outlet of the sterilization cylinder axially overlaps with the container outlet, the sterilized disposable container is discharged from the container outlet and enters the packaging device.

[0037] This invention achieves sterilization in the process before packaging disposable containers. By rotating the sterilization cylinder, the disposable containers are sterilized efficiently and thoroughly, which greatly improves production efficiency. Attached Figure Description

[0048] The rotary sterilization device for container packaging of this invention is applied to... Figure 1 The packaging equipment shown includes a frame 4, an input device 2, a sterilization device 1, and a sealing device 3. The input device 2 is connected to the sterilization device 1. The sterilization device 1 is located on the upper part of the frame 4, and the sealing device 3 is located in the frame 4, below the sterilization device 1. Disposable containers enter the sterilization device 1 through the input device 2 for stacking and sterilization, and then enter the sealing device 3 for sealing. The sealed disposable containers then proceed to the next process.

[0049] Figure 2 The structure of the rotary sterilization device 1 before container packaging according to this utility model is given, including a sterilization support 14 and a sterilization mechanism 13. An upper mounting plate 11 is installed on the top of the sterilization support 14, and a servo motor 12 is installed on the upper mounting plate 11. The sterilization mechanism 13 is disposed in the sterilization support 14 and connected to the servo motor 12 (see [reference]). Figure 3 ).

[0050] The structure of the sterilization mechanism is as follows Figure 3 It includes an upper sealing plate 134, a lower sealing plate 131, an upper turntable 133, a lower turntable 132, a sterilization medium inlet seat 135, a rotating shaft 136, and a sterilization cylinder 137. The upper end of the rotating shaft 136 is connected to the motor shaft of the servo motor 12, and the upper sealing plate 134, upper turntable 133, lower turntable 132, and lower sealing plate 131 are sequentially mounted on the rotating shaft 136 from top to bottom.

[0051] The structure of the lower sealing plate 131 is as follows Figure 4 An annular groove 1312, a central hole 1313, a container outlet 1314, and a mounting hole 1315 are provided on the lower turntable base plate 1311. The central hole 1313 is used to pass through the rotating shaft 136, the container outlet 1314 is used to dock with the packaging device 3, and the mounting hole 1315 is used to fix the lower sealing plate 131 to the sterilization bracket 14.

[0052] The structure of the lower turntable 132 is as follows Figure 5 The lower turntable base plate 1321 is provided with an annular groove 1322, a shaft mounting hole 1323, and a sterilization cylinder mounting hole 1324. The shaft mounting hole 1323 is used to install the lower end of the rotating shaft 136, and the sterilization cylinder mounting hole 1324 is used to install the lower end interface of the sterilization cylinder 137. The annular groove 1312 and the annular groove 1322 are coaxial, have the same structure, and have the same diameter. They are interlocked to form a closed annular slide, with built-in ball bearings, which allows the lower turntable 132 to rotate smoothly relative to the lower sealing plate 131 and ensures the stability of the gap.

[0053] The structure of the upper turntable 133 is as follows Figure 6 The upper turntable base plate 1331 is provided with an annular groove 1332, a shaft mounting hole 1333 and a sterilization cylinder mounting hole 1334. The shaft mounting hole 1333 is used to install the upper part of the rotating shaft 136, and the sterilization cylinder mounting hole 1334 is used to install the upper end of the sterilization cylinder 137.

[0054] The structure of the upper sealing plate 134 is as follows Figure 7 As shown, the upper turntable base plate 1341 is provided with a container inlet 1344, a mounting adjustment hole 1345, a sterilization medium inlet 1346, a mounting hole 1347, and an annular groove 1342. The container inlets 1344 and sterilization medium inlets 1346 of the upper sealing plate 134 are evenly distributed on a concentric circle centered on the central hole 1343 (two container inlets 1344 and six sterilization medium inlets 1346 are evenly distributed). The total number of container inlets 1344 and sterilization medium inlets 1346 on the upper sealing plate 134 (a total of eight) and their arrangement pattern are consistent with the arrangement pattern and number of sterilization cylinders 137, all on concentric circles of equal diameter. Four mounting holes 1347 are evenly distributed around each sterilization medium inlet 1346 for installing sterilization medium inlet seats 135. Besides connecting the upper sealing plate 134 and the upper mounting plate 11, the adjustment hole 1345 also serves another important function: adjusting the gap between the upper sealing plate 134 and the upper turntable 133 by loosening the connecting bolts. This adjusts the engagement clearance between the annular groove 1332 on the upper turntable 133 and the annular groove 1332 on the upper sealing plate 1342, ensuring smooth rotation of the placed balls. The annular grooves 1332 and 1342 are coaxial, have identical structures, and equal diameters. The container inlet 1344 and the sterilization medium inlet seat 135 on the upper sealing plate 134 both extend out of the upper mounting plate 11, facilitating connection to relevant interfaces.

[0055] The upper turntable 133 and the lower turntable 132 have the same structure. Multiple sterilization cylinders 137 are installed between the upper turntable 133 and the lower turntable 132. The sterilization cylinders 137 are evenly distributed around the rotating shaft 136. After the upper turntable 133, sterilization cylinders 137 and lower turntable 132 are installed, they are fixedly connected to the rotating shaft 136 and rotate together with the rotating shaft 136.

[0056] The container inlet 1344 on the upper sealing plate 134 and the container outlet 1314 on the lower sealing plate 131 are installed in a staggered manner (the container inlet 1344 and the container outlet 1314 cannot overlap axially). This ensures that the upper input port and lower output port of the sterilization cylinder 137 cannot be open simultaneously. For any given sterilization cylinder 137, it means that disposable containers cannot be both input and output at the same time. The purpose is to allow the disposable containers a certain residence time in the sterilization cylinder 137 to meet the sterilization process duration requirements. In this embodiment, eight sterilization cylinders are evenly distributed. Every 45-degree rotation of the sterilization mechanism 13 (360 degrees divided by 8 equals 45 degrees), the container inlet 1344 overlaps axially with the inlet of one sterilization cylinder 137 (the initial position is that the container inlet 1344 overlaps axially with the inlet of one of the sterilization cylinders 137). Therefore, in this embodiment, the container inlet 1344 on the upper sealing plate 134 and the container outlet 1314 on the lower sealing plate 131 are installed in a staggered manner of 135 degrees. When the sterilization cylinder 137 rotates 135 degrees, it axially overlaps with the container outlet 1314, allowing disposable containers to enter the sealing device 3, thus emptying the sterilization cylinder 137. A further 45-degree rotation (180 degrees relative to the initial position) axially overlaps with another container inlet 1344, allowing disposable containers to be fed into the inner cylinder 1372 of the sterilization cylinder 137 again, and this cycle repeats continuously. Simultaneously, another container inlet 1344 also axially overlaps with another sterilization cylinder 137, performing the same cycle. Container inlets 1344 and container outlets 1314 are arranged in pairs, the number of which depends on the sterilization time.

[0057] The servo motor 12 drives the upper turntable 133, sterilization cylinder 137 and lower turntable 132 to rotate together via the rotating shaft 136. When the upper inlet of the sterilization cylinder 137 is axially overlapped with the sterilization medium inlet 1346, the sterilization medium (such as chlorine dioxide gas) enters the sterilization cylinder 137 through the sterilization medium inlet 1352 for sterilization. When the lower end of the sterilization cylinder 137 is axially overlapped with the container outlet 1314, the sterilized disposable container enters the packaging device 3 through the container outlet 1314.

[0058] The structure of the sterilization medium inlet is as follows: Figure 8As shown, the inlet base 1351 is provided with a sterilization medium inlet 1352, a sterilization medium outlet 1353, and a mounting hole 1354. The mounting hole 1354 mates with the mounting hole 1347 to mount the inlet base 1351 onto the upper sealing plate 134. The sterilization medium inlet 1352 is connected to an external sterilization medium delivery pipe, and the sterilization medium outlet 1353 is connected to the outer cylinder 1371 in the sterilization cylinder 137.

[0059] The structure of sterilization cartridge 137 is as follows Figure 9 As shown, the device includes an outer cylinder 1371 and an inner cylinder 1372, with the inner cylinder 1372 disposed inside the outer cylinder 1371. Together, they form a sterilization cylinder 137. To facilitate the flow of the sterilization medium between the inner and outer cylinders, a slot 1373 is formed on the inner cylinder 1372. The two ends of the sterilization cylinder 137 are respectively installed in sterilization cylinder mounting holes 1324 in the lower turntable 132 and 1334 in the upper turntable 133. A rotating shaft 136 passes through and is fixed in the shaft mounting holes 1323 in the lower turntable 132 and 1333 in the upper turntable 133, or the rotating shaft 136 is keyed to the shaft mounting holes 1323 and 1333. In this way, the lower turntable 132, upper turntable 133, sterilization cylinder 137, and rotating shaft 136 are assembled into a single component unit, which is then placed on the lower sealing plate 131. Annular grooves 1313 and 1323 form a closed slide, with ball bearings arranged within the slide. The lower sealing plate 131 is fixedly connected to the sterilization support 14 via mounting holes 1315. Ball bearings are arranged in the annular groove 1343 of the upper turntable 134. The upper sealing plate 133 is placed on the upper turntable 134, causing the annular grooves 1343 and 1333 to close and form a slide. The upper sealing plate 134 is then connected to the upper mounting plate 11 via mounting adjustment holes 1345.

[0060] The operation process of the above-mentioned device is as follows.

[0061] The upper sealing plate 134 has two container inlets 1344 and six sterilization medium inlets 1346 evenly distributed. The lower sealing plate 131 has two container outlets 1311 evenly distributed. Eight sterilization cylinders 137 are evenly distributed between the upper turntable 133 and the lower turntable 132. Every time the sterilization mechanism 13 rotates 45 degrees (360 degrees divided by 8 equals 45 degrees), the container inlet 1344 axially overlaps with the inlet of one sterilization cylinder 137 (the initial position is that the container inlet 1344 axially overlaps with the inlet of one sterilization cylinder 137). The container inlets 1344 on the upper sealing plate 134 and the container outlets 1314 on the lower sealing plate 131 are installed with a 135-degree offset.

[0062] When a disposable container needs to be fed into the sterilization cylinder 137, the servo motor 12 drives the lower turntable 132, sterilization cylinder 137, and upper turntable 133 in the sterilization mechanism 13 to rotate via the rotating shaft 136, causing the two sterilization cylinders 137, the container inlets 1344 in the two upper sealing plates 134, and the input ports of the two external input devices to overlap axially. The disposable container enters the sterilization cylinder 137 (inner cylinder 1372) (the first sterilization cylinder 137). When the cumulative number of disposable containers passing through reaches a set number (external counter), the disposable container no longer enters the sterilization cylinder 137 (the first sterilization cylinder 137). The servo motor 12 drives a 45-degree rotation, and the sterilization medium enters the sterilization cylinder 137 through the sterilization medium outlet 1353 for sterilization (the first sterilization cylinder 137). Repeating the above process, disposable containers are fed into another set (the second set, two) of sterilization cylinders 137. When the set number of disposable containers is reached, the external input device is shut off, and no more disposable containers enter the sterilization cylinders 137. The servo motor 12 drives the cylinders to rotate another 45 degrees (a total rotation of 90 degrees, meaning two sets of sterilization cylinders have already undergone fully enclosed sterilization). When the sterilization cylinder 137 rotates 135 degrees (the first sterilization cylinder 137), it axially overlaps with the container outlet 1314. The sterilized disposable containers seamlessly enter the next process through the container outlet 1314, and the sterilization cylinder 137 (the first sterilization cylinder 137) is emptied. After rotating another 45 degrees (180 degrees relative to the initial position), the sterilization cylinder 137 (the first sterilization cylinder 137) axially overlaps with another container inlet 1344, allowing disposable containers to be fed into the inner cylinder 1372 of the sterilization cylinder 137 (the first sterilization cylinder 137) again. This cycle repeats continuously. Meanwhile, another container inlet 1344 also overlaps axially with another sterilization cylinder 137, performing the same cycle.
