[0002] Paper-plastic sterilization bags, also known as medical sterilization paper-plastic bags or disinfection packaging bags, are a type of breathable and antibacterial medical packaging material specifically designed for the sterilization of medical devices. They are one of the most commonly used packaging forms in hospital sterilization supply centers, typically used to assist in the sterilization of medical devices. Currently, most paper-plastic sterilization bags are packaged manually and then sealed using a sealing machine.

[0039] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0040] like Figures 1 to 12As shown in the figure, this disclosure proposes a fully automatic folding and packaging device for paper-plastic sterilization bags, including: a packaging machine housing 101, wherein a feeding structure is installed inside the packaging machine housing 101, the feeding structure includes a first rotating shaft 302, on which a paper-plastic sterilization bag roll 303 is mounted, a third rotating frame 304 is rotatably fitted inside the packaging machine housing 101, the third rotating frame 304 is snapped and fixed to the first rotating shaft 302, and a partition 103 is slidably fitted on one side of the packaging machine housing 101; a guiding structure, wherein the guiding structure includes multiple guiding rollers rotatably fitted inside the packaging machine housing 101, two upper squeezing rollers 207 are installed inside the packaging machine housing 101, and a connecting structure is installed between the upper squeezing rollers 207 and the packaging machine housing 101, the connecting structure including a connecting frame 201. 1. An adsorption and fixing structure is installed inside, including multiple first adsorption ports 203. A guide plate 503 is rotatably fitted inside the outer shell 101 of the baling machine. Multiple second adsorption ports 507 are opened on one side of the guide plate 503. An air pump 505 is fixed on one side of the outer shell 101 of the baling machine. The air pump 505's suction end is connected to the first adsorption ports 203 and the second adsorption ports 507. 2. A sliding adjustment structure is installed inside the outer shell 101 of the baling machine. The sliding adjustment structure includes two sliding frames 403 installed inside the outer shell 101 of the baling machine. A lower extrusion roller 404 is rotatably fitted inside one sliding frame 403, and a lower auxiliary roller 405 is rotatably fitted inside the other sliding frame 403. Heaters are installed inside the upper extrusion roller 207, the lower extrusion roller 404, and the lower auxiliary roller 405. A cutting head 410 is installed on the upper side of the lower extrusion roller 404.

[0041] Specifically, the paper-plastic sterilization bag roll 303 is placed on the first rotating shaft 302. During feeding, pulling the paper-plastic sterilization bag causes the roll 303 to rotate through the first rotating shaft 302, thus achieving smooth feeding. The roll can be pulled to the appropriate length as needed, making the device adaptable to medical devices of different sizes and specifications, thus making the device more flexible and expanding its application range. The paper-plastic sterilization bag is then guided by a guide roller, clamped by a lower extrusion roller 404 and a lower auxiliary roller 405, and pulled and transported by the up-and-down sliding of the lower extrusion roller 404 and the lower auxiliary roller 405. It can also be clamped and fixed by two upper extrusion rollers 207. Air is drawn in through the first suction port 203 to generate negative pressure. The paper-plastic sterilization bag is adsorbed and fixed to ensure its stability. The bottom of the paper-plastic sterilization bag is heat-sealed by the lower extrusion roller 404 and the lower auxiliary roller 405, and the top of the paper-plastic sterilization bag is heat-sealed by the two upper extrusion rollers 207, thus ensuring the fixation effect of the paper-plastic sterilization bag. The paper-plastic sterilization bag and medical device are supported by the guide plate 503. The paper-plastic sterilization bag is cut by the cutting head 410, and then the packaged paper-plastic sterilization bag is sent out guided by the guide plate 503, thus realizing the folding and packaging of the paper-plastic sterilization bag. A controller is installed on one side of the packaging machine shell 101. The operation of the device is controlled by the controller, thereby reducing labor costs, improving packaging efficiency, ensuring packaging effect, and thus ensuring the effect of subsequent sterilization.

[0042] In this embodiment, a first electric slide rail 102 is fixed on one side of the packaging machine housing 101. The output end of the first electric slide rail 102 is fixedly connected to the partition 103. A second rotating frame 301 is rotatably fitted inside the packaging machine housing 101. The second rotating frame 301 is rotatably connected to the first rotating shaft 302. A slot 305 is provided in the third rotating frame 304. The end of the first rotating shaft 302 passes through the paper-plastic sterilization bag roll 303 and is fixed in the slot 305.

[0043] Specifically, when it is necessary to replace the paper-plastic sterilization bag roll 303, the first electric slide rail 102 is activated, which drives the partition 103 to slide up and down, thereby removing the partition 103 from the paper-plastic sterilization bag roll 303. Then, the first rotating shaft 302 is manually pulled to rotate it, thereby pulling the first rotating shaft 302 out of the slot 305, thus disengaging the first rotating shaft 302 from the slot 305. Finally, the paper-plastic sterilization bag roll 303 is placed on the first rotating shaft 302. Then, the end of the first rotating shaft 302 is locked in the slot 305. Nuts can also be installed on both sides of the paper-plastic sterilization bag roll 303. Threads are provided on the first rotating shaft 302, and the nuts are threaded to the paper-plastic sterilization bag roll 303. When the paper-plastic sterilization bag roll 303 is pulled to rotate, the paper-plastic sterilization bag roll 303 can drive the third rotating frame 304 and the second rotating frame 301 to rotate through the first rotating shaft 302, thereby achieving a better feeding effect and making replacement more convenient, thus improving the working efficiency of the device.

[0044] The top of the packaging machine housing 101 is provided with a packaging opening 104. Two first grooves 105 are provided inside the packaging machine housing 101. The first grooves 105 are connected to the packaging opening 104. A blocking plate 106 is slidably fitted inside the first grooves 105. Two second electric slide rails 107 are fixed inside the packaging machine housing 101. The output end of the second electric slide rail 107 is fixedly connected to the blocking plate 106. The connecting frame 201 is fixedly connected to the blocking plate 106.

[0045] Specifically, when packaging is required, the second electric slide rail 107 is activated, which drives the blocking plate 106 to slide, allowing the blocking plate 106 to enter the first groove 105. At this time, the packaging opening 104 opens, and the sliding of the blocking plate 106 can drive the paper-plastic sterilization bag, thereby opening the opening at the top of the paper-plastic sterilization bag, so that the packaging opening 104 is connected to the paper-plastic sterilization bag, making it convenient to put the medical device into the paper-plastic sterilization bag, thus achieving the packaging effect. There is no need for manual opening and heat sealing of the paper-plastic sterilization bag, thereby reducing labor costs and improving work efficiency.

[0046] The connecting frame 201 has a first air chamber 202, and multiple first adsorption ports 203 are connected to the first air chamber 202. The connecting frame 201 has a clamping cavity 210, which has a triangular cavity structure in cross section. A hose is fixed on one side of the connecting frame 201, and the first air chamber 202 is connected to the air pump's suction end through the hose.

[0047] Specifically, when it is necessary to adsorb the paper-plastic sterilization bag, the air pump 505 is started, which draws air to create a negative pressure state in the first air chamber 202. The air is drawn through the first adsorption port 203. Since the first adsorption port 203 is in contact with the paper-plastic sealed bag, the two connecting frames 201 adsorb and fix the two sides of the paper-plastic sterilization bag. As the connecting frames 201 move, they can drive the paper-plastic sterilization bag to move, so that the paper-plastic sterilization bag can be opened and packaged. Adsorption and fixation can ensure its stability and prevent the paper-plastic sterilization bag from falling, thereby ensuring the smooth feeding of the paper-plastic sterilization bag, preventing material interruption, ensuring work efficiency, reducing maintenance frequency, and thus reducing the labor intensity of workers.

[0048] The bottom of the connecting frame 201 is provided with a first sliding groove 204, and a first rotating frame 206 is slidably fitted in the first sliding groove 204. A plurality of first springs 205 are fixed between the first rotating frame 206 and the groove wall of the first sliding groove 204. An electromagnet 209 is fixed in the connecting frame 201, and the electromagnet 209 is attracted and fixed to the first rotating frame 206. The upper extrusion roller 207 is rotatably fitted in the first rotating frame 206. The upper extrusion roller 207 has a hollow structure. The heater includes a first heating tube 208 installed in the upper extrusion roller 207. The first heating tube 208 is fixedly connected to the first rotating frame 206.

[0049] Specifically, when heat-sealing the top of the paper-plastic sterilization bag is required, the electromagnet 209 is activated, causing it to attract the first rotating frame 206. This causes the first rotating frame 206 to slide, stretching the first spring 205. The two first rotating frames 206 then move closer together, bringing the upper compression roller 207 into contact with the paper-plastic sterilization bag. Then, the first heating tube 208 is activated, heating the upper compression roller 207 and thus sterilizing the paper-plastic bag that is directly in contact with it. The bag is sealed, and a first electromagnetic brake 601 is installed inside the first rotating frame 206. When it is necessary to clamp and fix the paper-plastic sterilization bag, the first electromagnetic brake 601 can be used to fix the upper squeeze roller 207. At this time, the upper squeeze roller 207 no longer rotates, and the two first rotating frames 206 move closer to each other, so that the two upper squeeze rollers 207 can squeeze and fix the paper-plastic sterilization bag, thereby ensuring the stability of the paper-plastic sterilization bag during the packaging process, preventing the paper-plastic sterilization bag from slipping, thus ensuring the packaging effect and improving work efficiency.

[0050] The outer casing 101 of the baler has two fixed third electric slide rails 401. The output end of the third electric slide rail 401 is fixedly connected to the fourth electric slide rail 402, and the output end of the fourth electric slide rail 402 is fixedly connected to the sliding frame 403. The lower extrusion roller 404 and the lower auxiliary roller 405 are both hollow structures. The heater also includes a second heating tube 406 fixed inside the lower extrusion roller 404 and the lower auxiliary roller 405. A motor is installed in one of the sliding frames 403, and the motor drives the lower auxiliary roller 405 to rotate.

[0051] Specifically, activating the third electric slide rail 401 drives the fourth electric slide rail 402 to slide up and down, which in turn drives the sliding frame 403 to slide up and down, thereby causing the lower squeezing roller 404 and the lower auxiliary roller 405 to slide up and down. Activating the fourth electric slide rail 402 drives the sliding frame 403 to slide left and right, bringing the two sliding frames 403 closer together, and the lower squeezing roller 404 and the lower auxiliary roller 405 closer together. This allows the distance between the lower squeezing roller 404 and the lower auxiliary roller 405 to be adjusted as needed. When the lower squeezing roller 404 and the lower auxiliary roller 405 are fixing the paper-plastic sterilization bag and the food, the lower squeezing roller 404 and the lower auxiliary roller 405 can slide up and down at this time. By stretching the paper-plastic sterilization bag, or by fixing the lower extrusion roller 404 while the lower auxiliary roller 405 rotates actively, a better feeding effect can be achieved. When it is necessary to seal the bottom of the paper-plastic sterilization bag, the second heating tube 406 is energized, which heats the lower extrusion roller 404 and the lower auxiliary roller 405, thereby sealing the paper-plastic sterilization bag. The length of the paper-plastic sealing bag can be selected according to the needs, making the device more flexible and expanding its application range. Furthermore, the device can not only be used for packaging paper-plastic sterilization bags but also for cutting them, thus making it suitable for different tasks and expanding its application range.

[0052] A second groove 407 is provided on the sliding frame 403 that is rotatably connected to the lower extrusion roller 404. A cutting frame 409 is installed on the upper side of the lower extrusion roller 404. The cutting frame 409 is fixedly connected to the cutting head 410. The cutting frame 409 is slidably connected to the second groove 407. A second spring 408 is fixed between the cutting frame 409 and the groove wall of the second groove 407.

[0053] Specifically, after the paper-plastic sterilization bag is sealed, the guide plate 503 can guide the paper-plastic sterilization bag, causing it to tilt. The sliding frame 403 then slides upwards, causing the cutting head 410 to move the paper-plastic sterilization bag upwards and contact the connecting frame 201, thus enabling cutting of the paper-plastic sterilization bag. When cutting is not required, if the paper-plastic sterilization bag accidentally contacts the cutting head 410, the cutting frame 409 can be squeezed downwards, compressing the second spring 408. This provides a good cushioning effect, protecting the paper-plastic sterilization bag and ensuring the packaging effect, preventing damage to the paper-plastic sterilization bag, and reducing waste costs.

[0054] The guide plate 503 is located inside the outer casing 101 of the packaging machine, near the lower extrusion roller 404. A motor 501 is fixed to one side of the outer casing 101 of the packaging machine. A second rotating shaft 502 is rotatably connected inside the outer casing 101 of the packaging machine. The second rotating shaft 502 is fixedly connected to the output end of the motor 501 and to the guide plate 503. The motor 501 drives the second rotating shaft 502 to rotate, thereby driving the guide plate 503 to rotate, so that the guide plate 503 contacts the paper-plastic sterilization bag and guides the movement of the paper-plastic sterilization bag.

[0055] Specifically, when the guide plate 503 needs to guide the tilting and moving direction of the paper-plastic sterilization bag, the motor 501 is started. The motor 501 drives the second rotating shaft 502 to rotate, thereby driving the guide plate 503 to rotate. When the guide plate 503 contacts the paper-plastic sterilization bag, it adsorbs and fixes the paper-plastic sterilization bag. Then, as the guide plate 503 tilts, it can effectively guide the movement of the paper-plastic sterilization bag. Furthermore, when packaging and placing medical devices, the guide plate 503 can directly support the paper-plastic sterilization bag, thereby preventing the medical devices from having a large downward impact. This provides a good protective effect, prevents the paper-plastic sterilization bag from breaking, and improves the efficiency of packaging.

[0056] The outer shell 101 of the baler has a discharge port 508 on one side, and an air passage 506 is provided inside the second rotating shaft 502. The air passage 506 is connected to the air extraction end of the air pump 505. The guide plate 503 has a second air chamber 504, which is connected to the air passage 506 and the second adsorption port 507.

[0057] Specifically, when adsorption and fixation are required, the air pump 505 is started, which draws air to create a negative pressure state in the air passage 506, the second air chamber 504, and the first air chamber 202. This allows adsorption to occur from the first adsorption port 203 and the second adsorption port 507, ensuring the effective adsorption and fixation of the paper-plastic sterilization bag. The air pump 505 is connected to an electric valve via a three-way valve, ensuring that the first adsorption port 203 and the second adsorption port 507 can operate independently. This allows the device to flexibly transport the paper-plastic sterilization bag and improves work efficiency.

[0058] The guide roller includes a first roller body 306 and a second roller body 307 rotatably fitted inside the outer shell 101 of the packaging machine. The second roller body 307 is located between the lower extrusion roller 404 and the lower auxiliary roller 405, and the first roller body 306 is located between the lower auxiliary roller 405 and the paper-plastic sterilization bag roll 303. The lower extrusion roller 404 guides the paper-plastic sterilization bag, and the lower auxiliary roller 405 slides up and down to feed the paper-plastic sterilization bag.

[0059] Specifically, the paper-plastic sterilization bags are transported by the first roller 306 and the second roller 307. Multiple rollers can also be set up so that two adjacent rollers come into contact, which can achieve a better material guiding effect, improve work efficiency, and facilitate refeeding after the paper-plastic sterilization bag roll 303 is replaced, reducing the difficulty of using the device.

[0060] Workflow: Activating the first electric slide rail 102 causes the partition 103 to slide up and down, thus removing the partition 103 from the paper-plastic sterilization bag roll 303. Then, manually pulling the first rotating shaft 302 causes it to rotate, pulling it out of the slot 305 and disengaging it. The paper-plastic sterilization bag roll 303 is then placed onto the first rotating shaft 302, and the end of the first rotating shaft 302 is secured in the slot 305. The first roller 306 and second roller 307 assist in transporting the paper-plastic sterilization bag. Activating the fourth electric slide rail 402 allows for further transport. The fourth electric slide rail 402 drives the sliding frame 403 to slide left and right, thereby bringing the two sliding frames 403 closer together, and the lower squeeze roller 404 and the lower auxiliary roller 405 closer together, thus adjusting the distance between the lower squeeze roller 404 and the lower auxiliary roller 405. Then, the third electric slide rail 401 is activated, which drives the fourth electric slide rail 402 to slide up and down, thereby driving the sliding frame 403 to slide up and down, and thus driving the lower squeeze roller 404 and the lower auxiliary roller 405 to slide up and down, thus pulling and feeding the paper-plastic sterilization bag. The second electric slide rail 107 is activated, which drives the blocking plate 106 to slide, so that the blocking plate 106... 06 enters the first groove 105, thus opening the packaging opening 104. The sliding of the blocking plate 106 drives the paper-plastic sterilization bag, opening the top of the bag and connecting the packaging opening 104 to the bag for easy placement of medical devices. Then, the electromagnet 209 is activated, attracting the first rotating frame 206, causing it to slide. The first spring 205 is stretched, bringing the two rotating frames 206 closer together, allowing the upper compression roller 207 to contact the paper-plastic sterilization bag. Finally, the first heating tube 208 is activated, heating the upper compression roller 207. Heating is applied to seal the paper-plastic sterilization bag that is in direct contact with the upper extrusion roller 207. When the bottom of the paper-plastic sterilization bag needs to be sealed, the second heating tube 406 is energized, which heats the lower extrusion roller 404 and the lower auxiliary roller 405, thereby sealing the paper-plastic sterilization bag. After the paper-plastic sterilization bag is sealed, it can be guided by the guide plate 503, causing the paper-plastic sterilization bag to tilt. Then, the sliding frame 403 is slid upward, causing the cutting head 410 to drive the paper-plastic sterilization bag upward to contact the connecting frame 201, which can then be used to cut the paper-plastic sterilization bag, thereby realizing the packaging action of the paper-plastic sterilization bag.
