Reusable packaging materials include textiles (cotton cloth) and rigid containers. Sterilized packaging bags are a type of medical packaging material. Sterilized packaging bags are mainly used for medical or medical disinfection and sterilization. Suitable sterilization methods include EO ethylene oxide sterilization, steam high temperature and high pressure steam moist heat sterilization, and gamma cobalt-60 irradiation sterilization.

[0003] Sterilization packaging bags are made by heat-sealing a combination of paper and plastic composite film. The heat-sealing process requires the use of heating plates. However, the heating plates do not cool down for a long time on the production line, which can easily lead to heat accumulation on the heating plates, thereby damaging the materials and affecting the heat-sealing quality. This needs to be improved. Utility Model Content

Both the distribution pipe and the exhaust pipe are equipped with solenoid valves, and the air inlet of the distribution pipe is connected to a cooling fan.

[0007] Preferably, the inner wall of the molding box is provided with a fixing frame, which is symmetrically distributed about the bisector of the molding box. A drive roller is rotatably connected to the inner side of the fixing frame, and the drive roller is driven by a motor.

[0010] Preferably, a support base is fixedly connected to the inner wall of the molding box, the support base is located directly below the cutter, and the top of the cutter is fixedly connected to one end of the third hydraulic cylinder.

[0011] Preferably, the active rollers are provided in two sets, each set having two rollers, with the two sets of active rollers located on both sides of the heat sealing chain, and the active rollers are driven by a motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This device can control the temperature of the heat sealing chain and the first heating plate, and cool the heat sealing chain and the first heating plate in time to avoid the heat sealing chain and the first heating plate being too hot, thereby ensuring the sealing quality of the heat sealing chain and the first heating plate.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a vacuum adsorption easy-tear, anti-deformation, sterilization packaging bag forming device, including a frame 2, a guide roller frame 1 and a forming box 3 are arranged on the top of the frame 2, a fixing frame 10 is arranged on the inner wall of the forming box 3, the fixing frame 10 is symmetrically distributed about the bisector of the forming box 3, a drive roller 9 is rotatably connected to the inner side of the fixing frame 10, the drive roller 9 is driven by a motor, the drive roller 9 can drive the heat sealing chain 11 to rotate and seal both sides of the material by rotating, the heat sealing chain 11 is sleeved on the outer wall of the drive roller 9, and a first heating plate 16 is attached to the inner side of the heat sealing chain 11. The heat sealing chain 11 is used to seal both sides of the material, and the first heating plate 16 can heat the heat sealing chain 11 to ensure heat sealing. The heat-sealing effect when chain 11 contacts the material is achieved by fixing a first hydraulic cylinder 4, a second hydraulic cylinder 5, and a third hydraulic cylinder 6 to the outer wall of the forming box 3. One second hydraulic cylinder 5 is located at the top and bottom of the forming box 3. One end of the second hydraulic cylinder 5 is fixedly connected to the second heating plate 12. This structure allows the second heating plate 12 to be automatically adjusted in height via the second hydraulic cylinder 5, thus ensuring the sealing effect of the second heating plate 12 on the material. The second heating plate 12 is used to seal the ends of the material. A support base 15 is fixedly connected to the inner wall of the forming box 3. The support base 15 is located directly below the cutter 13. The top of the cutter 13 is fixedly connected to one end of the third hydraulic cylinder 6. This structure allows the third hydraulic cylinder 6 to push the cutter 13 to seal the material. The material is cut to complete the bag making process. A support base 15 supports the material, ensuring stable cutting and a smooth cut. One end of the first hydraulic cylinder 4 is fixedly connected to the upper end of the fixing frame 10 on the inner wall of the forming box 3. The fixing frame 10 and the forming box 3 form a lifting structure. This structure, through the first hydraulic cylinder 4, can adjust the height of the fixing frame 10 and its accessories, such as the heat-sealing chain 11, on the upper end of the forming box 3. This ensures the heat-sealing chain 11 contacts the material for effective heat sealing. The forming box 3 contains a heat-sealing chain 11, which is symmetrically distributed about the bisector of the forming box 3. One side of the heat-sealing chain 11 is equipped with a drive roller 14. There are two sets of drive rollers 14, each set containing two rollers. Located on both sides of the heat-sealing chain 11, the drive roller 14 is driven by a motor. This structure enables automatic material input through the rotation of the drive roller 14, thereby ensuring continuous sealing of the material. A second heating plate 12 is provided on one side of the drive roller 14. The second heating plate 12 is symmetrically distributed vertically about the bisector of the forming box 3. A cutter 13 is provided on one side of the second heating plate 12. A first cooling component 7 and a second cooling component 8 are respectively provided at one end of the heat-sealing chain 11 and the second heating plate 12. The second cooling component 8 has the same structure as the first cooling component 7. The guide roller frame 1 of this device can guide and convey paper and plastic composite film into the forming box 3. The first cooling component 7 includes a diversion pipe 73 and an exhaust pipe 71 located at the front and rear ends of the forming box 3, respectively.Both the diversion pipe 73 and the exhaust pipe 71 are equipped with solenoid valves 72. The air inlet of the diversion pipe 73 is connected to a cooling fan 74. The first cooling component 7 of this device can be used in conjunction with a temperature sensor. The temperature sensor detects the temperature of the heat-sealing chain 11 and the second heating plate 12. If the temperature is too high, the cooling fan 74 and the solenoid valves 72 are activated, making cooling more intelligent. The cooling fan 74 drives airflow, allowing the airflow to carry away heat from the heat-sealing chain 11 and the second heating plate 12, thus achieving heat dissipation.

[0024] Working principle: When using this vacuum adsorption easy-tear anti-deformation sterilization packaging bag forming device, the material is first guided into the forming box 3 by the guide roller frame 1. Under the conveying of the active roller 14, the material continues to move to the other end of the forming box 3. After entering the forming box 3, the material first contacts the heat sealing chain 11 to heat seal both sides of the material. Then the material comes to the second heating plate 12 to heat seal the end of the material. Finally, the third hydraulic cylinder 6 pushes the cutter 13 to cut the material. If the temperature of the heat sealing chain 11 and the second heating plate 12 rises during use, the cooling fan 74 and the solenoid valve 72 are activated, so that the airflow is sprayed out from the diversion pipe 73 to carry away the heat on the surface of the heat sealing chain 11 and the second heating plate 12 and discharge it from the exhaust pipe 71. After the cooling work is completed, the cooling fan 74 and the solenoid valve 72 are closed.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
