Abstract
Description
Technical Field
[0001] This invention belongs to the field of container packaging technology, specifically relating to sterilization packaging equipment for disposable containers. Background Technology
[0002] The packaging process is a crucial step in the production of disposable containers such as paper cups, plastic cups, fast food containers, yogurt cups, ice cream cups, sauce cups, self-heating food containers, fresh food packaging boxes, takeaway soup buckets, porridge buckets, and baking / dessert containers (collectively referred to as "disposable containers"). This process is completed by packaging equipment. Current packaging equipment generally lacks a sterilization step during packaging, which can easily lead to bacterial residues and shortened shelf life. Since disposable containers come into direct contact with drinking water, beverages, and food, microbial contamination can directly endanger the health of users, posing a health hazard.
[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 highly efficient disposable container sterilization packaging equipment that has a sterilization function during the packaging process. Summary of the Invention
[0028] To address the shortcomings of existing disposable container packaging technologies, this invention provides a multi-channel container high-efficiency sterilization packaging device with sterilization function and high production efficiency.
[0029] The multi-channel container high-efficiency sterilization and packaging equipment of the present invention adopts the following technical solution.
[0030] The packaging equipment includes a frame, an input device, a sealing device, a sterilization device, and a sealing device, which are arranged on the frame from top to bottom. The input device includes an input transmission mechanism, an input frame, an input gate mechanism, and an input conduit. The input transmission mechanism is mounted on the frame, the input frame is connected to the input transmission mechanism, the input frame is equipped with an input gate mechanism, and the input gate mechanism is connected to an input conduit. The sealing device includes a mounting plate and a sealing mechanism. The mounting plate is mounted on the frame and has rows of input ports. The number and position of the input ports in each row of input ports are consistent with the number and position of the input gate mechanisms on the input frame in the input device (when the input frame is directly above the row of input ports, the input ports in the row of input ports are aligned with the input gate mechanisms). A sealing mechanism is set on the mounting plate for each row of input ports. The sterilization device includes a connecting chamber, a sterilization cylinder, and a gate valve. The connecting chamber is connected to the frame, and the sterilization cylinder is arranged on the connecting chamber. The number of sterilization cylinders is consistent with the number of input ports in the input port column and is arranged coaxially in one-to-one correspondence. A gate valve is provided at the lower part of the sterilization cylinder. The packaging device includes a packaging transmission mechanism, a packaging base, a packaging bracket, a lifting mechanism, and a packaging unit. The packaging transmission mechanism is mounted on a frame, the packaging base is connected to the packaging transmission mechanism, the lifting mechanism is mounted on the packaging base, the packaging bracket is mounted on the lifting mechanism, the packaging unit is mounted on the packaging bracket, and a packaging material roller is mounted on the packaging bracket.
[0031] The further structure of the above-mentioned device is described below.
[0032] A conveying device is provided on the frame below the packaging unit. The conveying device can be a belt conveyor, roller conveyor, or other existing technology.
[0033] The input transmission mechanism uses a lead screw and nut pair moving mechanism, which is existing technology. The input frame is moved by the lead screw and nut transmission.
[0034] The input gate mechanism includes a gate body, a gate cylinder, and gate plates. The gate body is mounted on the input frame, and the upper end of the gate body is connected to the input conduit. Gate plate holes are provided on the gate body, and two gate plates are inserted into these holes. The gate cylinder is a double-acting cylinder. Each piston rod of the gate cylinder is hinged to the front end of the front hinge plate. The rear end of the front hinge plate, the valve plate, and the front end of the rear hinge plate are hinged together. The rear end of the rear hinge plate is hinged to the input frame. When the piston rod of the gate cylinder extends or retracts, it moves the gate plate within the gate plate holes, causing the gate body to open or close. When the gate plate is open, a disposable container can fall.
[0035] The input conduit is equipped with a counter to ensure consistent quantity of single-use containers.
[0036] The input conduit is an arc-shaped tube open at both ends, with its lower end connected to the input gate mechanism.
[0037] The sealing mechanism includes a sealing plate, a lever, and a cylinder. The cylinder is mounted on a mounting plate, and the lever is connected to the piston rod of the cylinder. The lever passes through a lever groove on the mounting plate and connects to the sealing plate, which is placed on top of the mounting plate. The extension and retraction of the cylinder piston rod moves the lever within the lever groove, causing the sealing plate to translate and thus opening or closing each input port row. One sealing mechanism is responsible for opening or closing one input port row.
[0038] The sterilization cylinder includes an outer cylinder and an inner cylinder, with the inner cylinder placed inside the outer cylinder and a gap between them. Grooves are distributed on the side of the inner cylinder. A reinforcing ring is provided on the inner cylinder, which provides reinforcement and support, and also creates a gap between the inner and outer cylinders.
[0039] The interior of the connecting chamber is a sterilization medium chamber. The connecting chamber is provided with an upper interface, a lower interface, and a sterilization medium interface. The number of upper interfaces, the number of lower interfaces, the number of input ports in each input port column, and the number of sterilization cylinders in the connecting chamber are the same. The upper interface, the lower interface, and the sterilization cylinder are coaxially arranged in a one-to-one correspondence. Each upper interface is connected to a sealing mechanism in an upper sealing device, and each lower interface is connected to a sterilization cylinder.
[0040] The gate valve includes a gate valve body and a gate plate. A gate valve slot is provided on the gate valve body between the upper and lower ports. Two gate plates are installed in the gate valve slot. The gate plates are provided with opening and closing holes. A spring is connected between the gate plates and the inner wall of the gate valve body.
[0041] A valve plate opening mechanism is provided between the valve plate and the upper sealing knife mechanism of the packaging unit in the packaging device. The valve plate opening mechanism has an opening / closing hole on the valve plate, and a gate pin is hinged to the packaging bracket. The gate pin is connected to the upper sealing and cutting mechanism in the packaging unit. The valve plate consists of two pieces, inserted parallel to each other into valve plate holes in the valve body. A spring connects the two valve plates, and each valve plate corresponds to one gate pin. The two gate pins are respectively connected to two sets of upper sealing and cutting mechanisms. The gate pin extends into the opening / closing hole of the valve plate along with the packaging bracket. During the sealing and cutting process, the upper sealing and cutting mechanism pushes the gate pin to rotate, causing the valve plate to open.
[0042] The packaging transmission mechanism employs a lead screw and nut pair mechanism, specifically a nut connected to a lead screw via a threaded connection. The lifting mechanism utilizes a lifting cylinder, with the packaging bracket connected to the piston rod of the lifting cylinder. The packaging transmission mechanism drives the packaging base to move on the frame, while the lifting mechanism drives the packaging bracket to move up and down.
[0043] The packaging unit includes a gate pin and a sealing and cutting mechanism. The gate pin is hinged to the packaging bracket via a pin shaft. The sealing and cutting mechanism includes an upper sealing and cutting mechanism, a lower sealing and cutting mechanism, a left sealing and cutting mechanism, and a right sealing and cutting mechanism arranged on the four sides of the packaging bracket. Each side of the sealing and cutting mechanism includes two sets arranged opposite to each other. The sealing and cutting mechanism includes a sealing and cutting knife and a sealing and cutting cylinder. The sealing and cutting knife is connected to the piston rod of the sealing and cutting cylinder. The sealing and cutting cylinder is installed on the packaging bracket. The gate pin is connected to the piston rod of the sealing and cutting cylinder in the upper sealing and cutting mechanism via a connecting plate. The connecting plate is fixedly connected to the piston rod of the upper sealing and cutting cylinder (moving with the piston rod). The connecting plate is provided with a gate pin hole. The gate pin is inserted into the gate pin hole. When the piston rod of the sealing and cutting cylinder extends or retracts, it drives the gate pin to rotate around the pin shaft through the connecting plate, thereby realizing the opening and closing of the valve plate. The number of gate pins is the same as that of the valve plates in the sterilization mechanism (2). The gate pins can rotate around the pin shaft. When the gate pins rise with the packaging bracket, they are inserted into the opening and closing holes on the valve plates. The lower end of the gate pins rotates inward under the drive of the piston rod of the sealing and cutting cylinder in the upper sealing and cutting mechanism, causing the two valve plates to open outward. When the gate pins fall, the two valve plates close under the action of the spring. The sealing and cutting knife adopts existing technology, completing the packaging by heat sealing and cutting the packaging plastic film.
[0044] Disposable containers are fed into the sterilization unit through the input device and stacked to complete the sterilization process. Then, they are seamlessly connected to the packaging device to complete the packaging. The packaged disposable containers (packages) are then dropped onto the conveyor device for output, completing the entire sterilization and packaging process.
[0045] This invention incorporates a sterilization process during packaging. The arrangement of the disposable container input, sterilization, and packaging stages is reasonable, and the structure is simple and smooth to operate. Through multi-station disposable container input, multi-tube sterilization, and packaging, the equipment's production efficiency is significantly improved. Attached Figure Description

[0061] The multi-channel container high-efficiency sterilization packaging equipment of the present invention, such as Figure 1 As shown, the system includes a frame 1, an input device 2, a sealing device 3, a sterilization device 4, a packaging device 5, and a conveyor belt 6. The input device 2, sealing device 3, sterilization device 4, packaging device 5, and conveyor belt 6 are all mounted on the frame 1 and arranged sequentially from top to bottom. Disposable containers are moved to the sealing device 3 via the input device 2, then enter the sterilization device 4 for stacking and sterilization. After sterilization, the disposable containers seamlessly enter the packaging device 5 for sealing. The sealed disposable containers then fall onto the conveyor belt 6 for output, completing the entire sterilization and packaging process.
[0062] like Figure 2As shown, the input device 2 includes an input transmission mechanism 21, an input frame 25, an input gate mechanism 24, and an input conduit 22. The input transmission mechanism 21 is mounted on the frame 1, and the input frame 25 is connected to it. Multiple input gate mechanisms 24 are mounted on the input frame 25, and each input gate mechanism 24 is connected to an input conduit 22. A counter 23 is mounted on the input conduit 22. The input transmission mechanism 21 employs a lead screw and nut pair moving mechanism. The lead screw is mounted on the frame 1 and connected to a drive motor. A nut threadedly connected to the lead screw is mounted on the input frame 25. The drive motor drives the lead screw to rotate, and the input frame 25 moves through the transmission of the lead screw and nut. To ensure smooth movement of the input frame 25, two sets of parallel lead screw and nut pair mechanisms can be configured, with the drive motors on both sets operating simultaneously. The input frame 25 is equipped with multiple sets of input gate mechanisms 24 and matching input conduits 22. The input frame 25 is driven to move through the transmission mechanism 21. Each time the input frame 25 moves to a different station, the input gate mechanism 24 on the input frame 25 can be aligned with a row of input ports 313 in the upper sealing device 3. This allows for the input of disposable containers through multiple channels, greatly improving equipment efficiency.
[0063] See Figure 3 The input conduit 22 is an arc-shaped tube open at both ends. The two ends of the input conduit body 221 are the input conduit inlet 222 and the input conduit outlet 223, respectively. The counter 23 is installed on the input conduit body 221. The disposable container enters the input conduit body 221 through the input conduit inlet 222, and after being counted by the counter 23, it enters the gate front port 2441 of the input gate mechanism 24 through the input conduit outlet 223.
[0064] See Figure 4 The input gate mechanism 24 includes a gate body 244, a front hinge plate 242, a rear hinge plate 243, a gate cylinder 241, and a gate plate 245. The gate body 244 is placed in the mounting hole 252 of the input frame 25 (see [reference]). Figure 5The gate body 244 has a front port 2441 and a rear port 2443 at its upper and lower ends, respectively. The front port 2441 connects to the inlet conduit outlet 223. A gate slot 2442 is provided in the middle of the gate body 244. Two gate plates 245 are symmetrically inserted into the gate slot 2442. The opening or closing of the gate valve is determined by the gap generated by the relative movement of the two gate plates 24. The front hinge plate 242 is straight with connecting holes at both ends. The rear hinge plate 243 is curved with hinge holes 2431 at both ends. The gate cylinder 241 is a double-acting cylinder with two piston rods that extend and retract simultaneously. The two piston rods of the gate cylinder 241 are connected to the front hinge plate 242 via hinge shafts 248. The rear end of the front hinge plate 242, the valve plate 245, and the front end of the rear hinge plate 243 are connected together via hinge shafts 247. The rear end of the rear hinge plate 243 is fixed to the mounting hole 253 of the input frame 25 via a hinge pin (see...). Figure 5 A washer 246 is provided between the rear hinge plate 243 and the input frame 25. The input gate mechanism 24, through the extension and retraction of the gate cylinder 241, and under the combined action of the front hinge plate 242 and the rear hinge plate 243 (similar to the opening and closing of jaws), causes the gate plates 245 to move in opposite directions within the gate plate slot 2442. The opening or closing of the gate body 244 is achieved by adjusting the gap between the two gate plates 245. Since the gate cylinder 241 is only connected to the front hinge plate 242 through its piston rod, when the piston rod of the gate cylinder 241 extends and drives the front hinge plate 242 to move, the entire gate cylinder 241 moves closer to the gate body 244.
[0065] See Figure 5 The input frame 25 is provided with mounting holes 251, gate mounting holes 252, and connecting holes 253. The input frame 25 is mounted on the input transmission mechanism through the mounting holes 251. The input frame 25 is provided with multiple ( Figure 5 There are 5 gate mounting holes 252, and each gate mounting hole 252 is used to install an input gate mechanism 24. The connecting hole 253 is used to install the rear hinge plate 243 in the input gate mechanism 24.
[0066] Figure 6 The structure of the sealing device 3 is shown, including a mounting plate 31 and a sealing mechanism 32. The mounting plate 31 is mounted on the frame 1. Figure 7 As shown, the mounting plate 31 has multiple input port rows on the mounting base plate 311, each input port row has multiple input ports 313, and a lever groove 312 is provided on the outer side of each input port row. A sealing mechanism 32 is provided on the mounting base plate 311 corresponding to each input port row; the opening or closing of all input ports 313 in an input port row is achieved through the sealing mechanism 32. Figure 8As shown, the sealing mechanism 32 includes a sealing plate 321, a lever 322, a cylinder 323, and a cylinder bracket 324. Two cylinders 323 are provided (corresponding to lever slots 312 on the outer side of each input port row), and are respectively mounted on the underside (back side) of the mounting base 311 via the cylinder bracket 324. The lever 322 is connected to the piston rod of the cylinder 323, and passes through the lever slot 312 on the mounting base 311 to connect with the sealing plate 321. The sealing plate 321 is located on the top side (front side) of the mounting base 311. The extension and retraction of the piston rod of the cylinder 323 drives the lever 322 to move within the lever slot 312, causing the sealing plate 321 to translate on the mounting base 311, thus opening or closing each input port row 313. One sealing mechanism 32 is responsible for opening or closing one row of input ports. When a row of inlets 313 needs to be opened to allow disposable containers to pass through, the piston rod of the cylinder 323 in the corresponding sealing mechanism 32 extends, and drives the sealing plate 321 to move through the lever 322, so that all the inlets 313 in this row are opened.
[0067] Figure 9 A schematic diagram of the sterilization device 4 is provided, including a connecting clam 42, a sterilization cylinder 41, a gate valve body 44, and a gate plate 45. The connecting clam 42 is connected to the frame 1 via a clamping clip 43 (which has mounting holes 431) and is located below the upper sealing device 3. The sterilization cylinder 41 is mounted on the connecting clam 42, and the number of sterilization cylinders 41 is consistent with the number of input ports 313 in each input port row on the mounting base plate 311 in the upper sealing device 3, and they are coaxially aligned one-to-one. Figure 10 A schematic diagram of the sterilization cartridge 41 is provided, including an outer cartridge 411 and an inner cartridge 412 placed within the outer cartridge 411. The outer cartridge 411 and the inner cartridge 412 have the same length. The two ends of the outer cartridge 411 are the upper port 4111 and the lower port 4112, respectively, and the outer end of the inner cartridge 412 is the upper port 4121. The inner cartridge 412 has grooves 4122 distributed on its side for the flow of the sterilization medium within the sterilization cartridge 41. A reinforcing ring 4123 is provided on the inner cartridge 412, which serves to strengthen and support the cartridge. The inner cartridge 412 is installed inside the outer cartridge 411, and the upper port 4121 of the inner cartridge is flush with the upper port 4111 of the outer cartridge.
[0068] Figure 11The structure of the connecting clam 42 is given. The interior of the connecting clam 42 is a sterilization medium cavity 424. An upper interface 422 is provided on the top surface of the clam body 421, and a lower interface 423 and a sterilization medium interface 425 are provided on the bottom surface. All interfaces 422, 423, and 425 communicate with the sterilization medium cavity 424. Each upper interface 422 on the connecting clam 42 corresponds to each input port row 313. The number of upper interfaces 422 is the same as the number of input ports 313 in each input port row on the mounting base plate 311 in the upper sealing device 3, and their positions correspond one-to-one. The number of lower interfaces 423 is the same as the number of upper interfaces 422, and they correspond one-to-one. Each lower interface 423 connects to a sterilization cylinder 41, and the lower interface 423 is connected to the upper port 4111 of the outer cylinder. The sterilization medium interface 425 is used to connect to a sterilization medium introduction device, and the introduced sterilization medium flows within the sterilization medium cavity 424. The sterilization medium in the sterilization medium cavity 424 enters the inner cylinder 412 through the lower port 423.
[0069] Figure 12 A cross-sectional view of the gate valve body 44 is provided. The upper and lower ends of the gate valve body 44 are the upper port 441 and the lower port 442, respectively. The upper port 441 is connected to the lower port 4112 of the outer cylinder. A gate valve slot 443 is provided on the gate valve body 44 between the upper and lower ports. Two gate plates 45 are symmetrically installed in the gate valve slot 443. The gate plates 45 are provided with opening and closing holes 451. A gate pin 505 (see [reference]) is inserted into the opening and closing holes 451. Figure 14 The gate valve is opened by rotating the gate pin 505 to move the gate 45. A spring 46 is connected between the gate 45 and the inner wall of the valve body 44. One end of the spring 46 is connected to the gate 45, and the other end is connected to the inner wall of the valve body 44. The spring 46 serves to return the gate 45 to its original position. When there is no external force, the two gates 45 are in contact (closed), and the valve is in the closed state. When an external force is applied (when the direction of the force is consistent with the extension direction of the plane of the gate 45, the force is greater than the tension of the spring 46), the gate 45 moves along the valve slot 443 away from the center of the valve body 44. The gap between the two gates 45 gradually increases, and the spring 46 is stretched to generate a rebound elastic force. When the gap between the two gates 45 exceeds the maximum port diameter of the disposable container, the disposable container can pass through. When the external force is released, the spring 46 rebounds, and the gate 45 moves toward the center of the gate valve body 44 under the action of the spring 46 rebound force, so that the gate valve is closed.
[0070] Figure 13A schematic diagram of the packaging device 5 is provided, including a packaging transmission mechanism 504, a packaging base 511, a packaging support 501, a lifting cylinder 506, an upper sealing cylinder 502, an upper sealing cutter 503, a gate pin 505, a lower sealing cylinder 507, a lower sealing cutter 508, a side sealing cylinder 509, and a side sealing cutter 510. The packaging transmission mechanism 504 is mounted on the frame 1 and employs a screw-nut pair mechanism. The screw is mounted on the frame 1 and connected to the drive motor. The packaging base 511 is connected to the packaging transmission mechanism 504, specifically through a nut threaded connection to the screw. The lifting cylinder 506 is mounted on the packaging base 511, and the packaging support 501 is connected to the piston rod of the lifting cylinder 506. The packaging transmission mechanism 504 drives the packaging base 511 to move horizontally, and the lifting cylinder 506 drives the packaging support 501 to move up and down through the extension and retraction of its piston rod. To ensure smooth movement and lifting of the packaging bracket 501, two sets of parallel screw-nut pairs are provided. Each set of screw-nut pairs is connected to a packaging seat 511, and each packaging seat 511 is equipped with two lifting cylinders. The packaging bracket 501 is connected to the piston rods of four lifting cylinders 506. A gate pin 505 is provided on the packaging bracket 501. The gate pin 505 controls the opening and closing of the gate 45 in the sterilization mechanism 4 as the packaging bracket 501 moves up and down. An upper sealing cylinder 502 and a lower sealing cylinder 507 are provided at the top and bottom of the packaging bracket 501. Side sealing cylinders 509 are provided on both sides of the packaging bracket 501. An upper sealing cutter 503 is connected to the piston rod of the upper sealing cylinder 502, a lower sealing cutter 508 is connected to the piston rod of the lower sealing cylinder 507, and a side sealing cutter 510 is connected to the piston rod of the side sealing cylinder 509.
[0071] Figure 14 The structure of the gate pin 505 is shown. It is crank-shaped, with the upper end of the gate pin 505 being the upper end head 5051 and the lower end being the lower end face 5053. A gate pin shaft 5052 is provided on the gate pin 505 between the upper end head 5051 and the lower end face 5053, and their vertical center lines do not coincide. The gate pin 505 is mounted on the encapsulation bracket 501 through the gate pin shaft 5052, and the gate pin 505 can rotate around the gate pin shaft 5052. A spring is provided between the gate pin 505 and the encapsulation bracket 501. Without external force, the spring tension keeps the upper end head 5051 against the encapsulation bracket 501, always vertically upward, so that the upper end head 5051 can be inserted into the opening and closing hole 451 of the gate 45. When an external force (horizontal push or pull) is applied to the lower end face 5053 of the gate pin, the gate pin 505 rotates around the gate pin shaft 5052, and the direction of movement of the upper end 5051 of the gate pin is opposite to the direction of movement of the lower end face 5053 of the gate pin.
[0072] When the sealing bracket 501 is raised, the upper end 5051 of the gate pin is inserted into the opening and closing hole 451 of the gate 45. The back of the upper sealing cutter 503 (the front is the heat-sealing cutting blade) is in contact with the lower end face 5053 of the gate pin. When the upper sealing cutter 503 moves inward under the action of the upper sealing cylinder 502, it drives the gate 45 to move outward (in the opposite direction to the movement of the upper sealing cutter 503), thus opening the two gates 45. After the sealing and cutting are completed, when the upper sealing cutter 503 moves outward under the action of the upper sealing cylinder 502, it drives the gate 45 to move inward (in the opposite direction to the movement of the upper sealing cutter 503), and the two gates 45 close.
[0073] When the gate 45 is pushed outward by the upper end of the pin 5051, the spring 46 is stretched, generating a restoring force. When the upper sealing cutter 503 moves outward under the action of the upper sealing cylinder 502, the gate 45 moves inward (opposite to the direction of movement of the upper sealing cutter 503) under the combined action of the restoring force of the spring 46 and the upper end of the pin 5051, thus closing the gate 45. The spring 46 serves as a "double insurance" function for the gate 45 to return to its position (close), supplementing or assisting the function of the upper end of the pin 5051.
[0074] The sealed disposable containers are lowered from the sealing bracket 501 onto the conveyor device 6 and transported away. The conveyor device 6 can be any existing conveyor, such as a belt conveyor or a roller conveyor.
[0075] All electric components can be electrically connected to the controller and operated by the controller.
[0076] The operation process of the above-mentioned equipment is as follows.
[0077] 1. The input frame 25 is moved to a position directly above a row of input ports 313 in the upper sealing device 3 by the input transmission mechanism 21. The position of a row of input ports constitutes one workstation. The piston rod of the gate cylinder 241 in the input gate mechanism 24 extends, opening the gate body 244. At the same time, the sealing mechanism 32 in the sealing mechanism 32 at this workstation opens the row of input ports 313. In this way, the input conduit 22 is connected to the inner cylinder 412 of the sterilization cylinder 41, and the disposable container enters the inner cylinder 412 through the sterilization medium chamber 424 via the input conduit 22.
[0078] When the counter 23 in the input conduit 22 reaches the set quantity, the gate 244 closes, and the input port 313 of that column closes. Disposable containers no longer enter the inner cylinder 412.
[0079] 2. The input transmission mechanism 21 drives the input frame 25 to move to the next station. Following the above process, disposable containers are input into the corresponding inner cylinder 412 through the next column of input ports 313.
[0080] 3. When all input ports 313 of a workstation are closed, the sterilization medium (such as chlorine dioxide) enters the sterilization medium chamber 424 through the sterilization medium interface 425, and then enters all connected cavities and sterilization cylinders 41 through the sterilization medium chamber 424 for sterilization.
[0081] 4. When the sterilization time of the disposable container in the sterilization tube 41 reaches the required duration, it enters the packaging process.
[0082] First, the packaging device 5 reaches the corresponding work station in advance, and the packaging transmission mechanism 504 drives the packaging base 511 to move to the position of the sterilization tube 41 that needs to be packaged.
[0083] Next, the piston rod of the lifting cylinder 506 extends, driving the packaging bracket 501 to rise, causing the gate pin 505 to extend into the opening and closing hole 451 on the gate 45. The back of the upper sealing cutter 503 (the front is the heat-sealing cutting blade) is in contact with the lower end face 5053 of the gate pin. When the upper sealing cutter 503 moves inward under the action of the upper sealing cylinder 502, it drives the gate 45 to move outward (in the opposite direction to the movement of the upper sealing cutter 503), opening the gate 45 and allowing the disposable container to fall in. According to the set process flow, the upper sealing cylinder 502, lower sealing cylinder 507, and side sealing cylinder 509 of the packaging bracket 501 drive the corresponding upper sealing cutter 503, lower sealing cutter 508, and side sealing cutter 510 to achieve heat-sealing cutting, completing the entire packaging process. After the packaging at this station is completed, the packaging transmission mechanism 504 drives the packaging base 511 to the next station that needs to be packaged.
[0084] 5. The sealed disposable container is lowered from the sealing bracket 501 onto the conveyor device 6 and transported away. The conveyor device 6 can be any existing conveyor, such as a belt conveyor or a roller conveyor.
[0085] 6. After the sealing and cutting are completed, when the upper sealing cutter 503 moves outward under the action of the upper sealing cylinder 502, it drives the gate 45 to move inward (in the opposite direction to the movement of the upper sealing cutter 503), and the gate 45 closes.
