Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of ultraviolet sterilization technology, specifically to a sterilization device for food packaging bags. Background Technology
[0002] The inner food packaging bag in a food packaging bag can come into direct contact with the food. Usually, the inner food packaging bag is unrolled and transported in the form of a film before packaging the food. Before being transported to the forming and packaging process, when the packaging bag film is disinfected, ultraviolet germicidal lamps can be installed on both sides of the packaging bag film to complete the final sterilization treatment before the packaging bag film is formed.
[0003] Bacteria can be effectively killed within 1 meter of the irradiation range of the ultraviolet germicidal lamp. The conveyed packaging film needs to avoid overlapping. The packaging film needs to stay in the sterilization area of the ultraviolet germicidal lamp for more than 30 seconds. If the packaging film is conveyed in a straight path, sufficient space needs to be reserved between the unwinding and forming packaging processes, resulting in the technical solution occupying too much space in the workshop.
[0004] The inventors proposed a food packaging bag sterilization device, which shortens the overall length of the packaging bag film conveying assembly and reduces the space occupied by the equipment in the workshop by staggering the conveying rollers of the packaging bag film and the ultraviolet germicidal lamp, without changing the residence time of the packaging bag film in the ultraviolet germicidal lamp irradiation area.

[0037] See attached document Figure 1-6 This utility model provides a food packaging bag sterilization device, comprising the following structure:
[0038] Two trusses 1, with multiple guide rollers 11 connected to the front of the opposite sides of the two trusses 1 in an offset manner, and multiple ultraviolet germicidal lamps 4 are offset at the top and bottom of the trusses 1, and tensioning frames 5 are fixed at the rear of the opposite sides of the two trusses 1.
[0039] Mounting bracket 7, the top of mounting bracket 7 is detachably snapped with a slide 71, a winding motor 72 is fixedly mounted on the front side of the top of slide 71, and an air shaft 73 is fixedly mounted on the rear output end of winding motor 72. The front end of the air shaft 73 is movably connected to the front side of the top of slide 71.
[0040] In this embodiment, side plates 12 are fixedly provided on the outer sides of both trusses 1. Top plates 13 and bottom plates 14 are fixedly provided on the top and bottom of the two side plates 12, respectively. The front parts of the two side plates 12 are detachably snapped to the front and rear sides of the end plate 15, respectively. A feed port is fixedly provided in the middle of the end plate 15.
[0041] The side plate 12, bottom plate 14 and top plate 13 are configured to provide shielding protection for the working area of the guide roller 11 and the ultraviolet germicidal lamp 4. The packaging bag film that needs to be disinfected is conveyed to the outside of the guide roller through the feed port of the end plate 15. The guide roller 11 completes the up and down wave-like guidance of the packaging bag film. The ultraviolet germicidal lamp irradiates and sterilizes the packaging bag film at the adjacent sides of the upper and lower included angles. Compared with the existing straight conveying scheme, it effectively reduces the footprint of the equipment.
[0042] In this embodiment, the top and bottom of the truss 1 are staggered and snapped with multiple positioning frames 2. The top of the positioning frame 2 is fixed with a positioning hole 21. The outer side of the positioning frame 2 is slidably connected with a positioning seat 22 that matches the positioning hole 21. The outer side of the positioning seat 22 is threadedly connected with a positioning bolt 23. The rear side of the positioning bolt 23 abuts against the outer side of the positioning frame 2. The middle part of the positioning seat 22 is fixed with a lamp holder 3. The output end of the lamp holder 3 is electrically connected to the input end of the ultraviolet germicidal lamp 4.
[0043] The positioning bolt 23 cooperates with the positioning seat 22 to adjust the working height of the lamp holder 3 outside the positioning frame 2, thereby adjusting the irradiation distance between the ultraviolet germicidal lamp 4 and the outer packaging bag film of the guide roller 11.
[0044] In this embodiment, the guide roller 11 located above the truss 1 corresponds to the position of the ultraviolet germicidal lamp 4 located below the truss 1.
[0045] The guide rollers 11 are staggered vertically, and the ultraviolet germicidal lamps 4 are also staggered vertically. At this time, the guide rollers 11 above the truss 1 are directly facing the ultraviolet germicidal lamps 4 below the truss 1, so that each ultraviolet germicidal lamp can irradiate the adjacent sides of the packaging bag film that is guided and conveyed vertically in a wave-like manner.
[0046] In this embodiment, the top and bottom of the two tensioning frames 5 are slidably connected to slide blocks 51, and the opposite sides of the two slide blocks 51 are movably connected to the front and rear ends of the tensioning roller 52, respectively. A connecting rod 53 is movably connected to the outer side of the slide block 51.
[0047] In this embodiment, a guide frame 6 is fixedly provided on the outer side of the tensioning frame 5, a return spring 61 is snapped into the inner side of the guide frame 6, a guide seat 62 is snapped into the front end of the return spring 61, the outer side of the guide seat 62 is slidably connected to the middle part of the guide frame 6, and the top and bottom of the guide seat 62 are movably connected to the right ends of the two connecting rods 53 respectively.
[0048] The slide 51 cooperates with the tensioning frame 5 to complete the setting of the tensioning roller 52. The return spring 61 pushes the guide seat 62 on the guide frame 6. The guide seat 62 cooperates with the connecting rod 53 to maintain the working position of the slide 51 on the tensioning frame 5, and completes the conveying and tensioning process of the packaging bag film.
[0049] Detailed operating procedures:
[0050] The packaging film is guided by the guide roller 11 and sterilized by the ultraviolet germicidal lamp 4. It is then conveyed and tightened by the tension roller 52. The winding motor 72 works with the air shaft 73. The user places the paper tube on the outside of the air shaft 73 to wind up the sterilized packaging film, or the winding motor 72 stops working and the sterilized packaging film is sent into the forming and packaging process.
[0051] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
