Description

Technical Field

[0001] The present application relates to the technical field of medical device production equipment, and in particular to a sheet material packaging equipment. Background Art

[0002] Patches, antipyretic patches, masks and other medical supplies are frequently used in people's daily lives and are often carried with them. In order to ensure the convenience of carrying and using such medical supplies, single-piece independent packaging is often used. At the same time, this packaging method also ensures that such medical supplies are cleaner and more hygienic during storage, transportation and carrying. On the other hand, the widespread use of independent packaging will generate a large amount of waste packaging, which will lead to waste of resources and environmental damage.

[0003] In order to reduce the generation of waste packaging, the sheet-like characteristics of bandages, fever patches and masks can be used to reduce their volume by folding them before packaging them independently, which can reduce the amount of packaging materials used and improve the convenience of carrying. For example, the Chinese invention patent with the authorization announcement number CN114084513B discloses an environmentally friendly and hygienic portable mask. By folding the mask before packaging, the size of the packaging bag is reduced, the amount of packaging materials used is reduced, the impact of packaging waste on the environment is reduced, and the convenience of carrying is improved.

[0004] Currently, packaging equipment on the market often uses transparent plastic as packaging material to package such sheet materials. The packaging bag formed by this packaging method is completely sealed, and gas cannot penetrate the packaging bag, so the sheet materials in the packaging bag cannot be sterilized by ethylene oxide.

[0071] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions.

[0073] See also Figure 1-Figure 11 As shown, the embodiment of the present application provides a sheet material packaging device, including a frame 10 and an unwinding part 20 and a heat sealing part 30 arranged on the frame 10, wherein:

[0074] See also Figure 1-Figure 4As shown, the unwinding part 20 is used to store and provide packaging materials, and includes two unwinding rollers 21 for supporting packaging materials. The packaging materials supported on the two unwinding rollers 21 are respectively coated paper 60 and medical dialysis paper 70. After the unwinding end of the unwinding roller 21, a plurality of intermediate rollers 22 for guiding the movement direction of the packaging materials and a plurality of tension wheels for applying tension to the packaging materials are provided. Due to the different tensile deformation caused by the material difference of the coated paper 60 and the medical dialysis paper 70, the two rolls of packaging materials cannot be synchronized, and the coated paper 60 and the medical dialysis paper 70 are pre-printed with product information. If they cannot be synchronized, the information will be misplaced. Therefore, it can be adjusted by adjusting the degree of compression of the tension wheel to apply a certain tension to the film to keep it at a stable conveying speed. It is also possible to set easy-to-identify and track marks, such as color strips, grooves or special marks, on the two rolls of packaging materials, especially at their edges or specific positions, and these marks can be monitored and identified in real time by high-precision photoelectric sensors or other detection devices. The relative position relationship between the marks on the two rolls of packaging materials can be accurately measured. Once the deviation of the mark positions on the two rolls of packaging materials is identified, a signal is immediately sent to the control system. The control system will automatically adjust the conveying speed or position of the two rolls of packaging materials based on these signals so that they can regain synchronization. The movement path of the packaging materials on the two unwinding rollers 21 includes a parallel section 80 that moves parallel to each other. The packaging materials on the two unwinding rollers 21 form an entrance 90 for sheet materials at the beginning of the parallel section 80. This entrance 90 is used for sheet materials to enter the parallel section 80, so that the sheet materials are sandwiched between the two packaging materials of the coated paper 60 and the medical dialysis paper 70, and the sheet materials move together with the two packaging materials.

[0075] See also Figure 5-Figure 9 As shown, the heat sealing part 30 is used to heat-seal the coated paper 60 and the medical dialysis paper 70 to form a packaging bag containing sheet materials. The heat sealing part 30 includes a downward pressing device 31 and an upward pushing device 32, and the downward pressing device 31 and the upward pushing device 32 are connected through a side support plate 33. The downward pressing device 31 includes a heating plate 311 and a downward pressing power mechanism for driving the heating plate 311 to move downward, the downward pressing power mechanism is connected to the side support plate 33, and the heating plate 311 is connected to the bottom end of the downward pressing power mechanism. The upward pushing device 32 includes a top plate 321 and an upward pushing power mechanism for driving the top plate 321 to move upward, the upward pushing power mechanism is connected to the side support plate 33, the top plate 321 is connected to the top of the upward pushing power mechanism, the top plate 321 is located directly below the heating plate 311, and the heating plate 311 and the top plate 321 are respectively located on opposite sides of the parallel section 80. When the sheet material runs between the heating plate 311 and the top plate 321, the downward pressing power mechanism and the upward pushing power mechanism respectively drive the heating plate 311 and the top plate 321 to press tightly between the two packaging materials containing the sheet material, thereby forming a packaging bag containing the sheet material.

[0076] Different from the transparent plastic packaging material released by one unwinding roller 21 on the market, the above-mentioned sheet material packaging equipment can release two kinds of packaging materials, namely, coated paper 60 and medical dialysis paper 70, at the same time through two unwinding rollers 21. Medical dialysis paper 70 allows ethylene oxide sterilization factor or high-temperature steam to pass through, so as to sterilize the medical device inside the package. At the same time, it can effectively prevent bacteria, dust and other microorganisms from entering the package, and maintain the sterility of the medical device. Based on the characteristics of medical dialysis paper 70, the packaged sheet material can achieve ethylene oxide sterilization of the sheet material in the packaging bag.

The top plate 321 is driven to move up and down along the guide shaft 326 by the rotation of the eccentric wheel 327. The two unwinding rollers 21 are respectively located on opposite sides of the parallel section 80. The unwinding roller 21 supporting the coated paper 60 is located above the unwinding roller 21 supporting the medical dialysis paper 70 .

There are a plurality of grooves in the middle of the metal upper mold 3111 and the silicone lower mold 3211 that can accommodate a sheet material, so that when the metal upper mold 3111 and the silicone lower mold 3211 are aligned and hot-pressed, an independent package with a closed outer edge can be formed.

The slitting part 40 includes a slitting frame 41 and a slitting roller group arranged on the slitting frame 41. The slitting roller group includes a knife roller 421 and an anvil roller 422 rotatably connected to the slitting frame 41, and the knife roller 421 and the anvil roller 422 are connected to the slitting motor through a gear group 43.
