Description

Technical Field

[0001] This utility model belongs to the field of special dietary filling technology, and in particular relates to a packaging sterilization device for special dietary filling. Background Technology

[0002] In the field of special dietary food production, powdered special dietary foods require special attention to sterilization during filling due to their unique composition and stringent hygiene requirements. Currently, existing filling machines, which are highly automated, directly bag the packaging film before filling. However, during the short-distance transport of the packaging film on the filling machine, sterilization is often lacking. Typically, the packaging film roll is sterilized separately before the conveyor mechanism of the filling machine. This method is prone to incomplete sterilization due to the thickness of the film roll. Furthermore, after the packaging film roll is installed on the conveyor mechanism of the filling machine, it is pulled through the conveyor for bag cutting. This transport process is carried out in an exposed environment, making the packaging film susceptible to recontamination. Therefore, it is necessary to research a packaging sterilization device before the packaging film enters the filling machine for filling. Utility Model Content

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] As shown in the figure, a special food filling packaging sterilization device includes a box body 1. A door 2 is provided on the front side of the box body 1, and a strip-shaped feed inlet 101 is horizontally opened on the front side of the box body 1 below the door 2. Inside the box body 1, a feed roller group 3 is provided behind the feed inlet 101. Multiple sets of spaced guide rollers 401 groups 4 are longitudinally arranged diagonally above and behind the feed roller group 3 inside the box body 1. A strip-shaped discharge outlet 102 is horizontally opened on the rear side of the box body 1. An discharge roller group 5 is provided inside the box body 1 in front of the discharge outlet 102, and the discharge roller group 5 is located diagonally above and behind the uppermost guide roller group 401 group 4. Ultraviolet lamps 6 are provided on the rear side wall of the box body 1 and between adjacent sets of guide roller groups 401 groups 4. In this embodiment, an ultraviolet lamp 6 is provided between adjacent sets of guide roller groups 401 groups 4 on the rear side of each door 2. In this embodiment, the device is located at the rear of the filling machine, and the outlet 102 of the device corresponds to the back of the filling machine, that is, the device and the filling machine are placed back to back. In use, the packaging film 1001 extends from the packaging film roll 10, enters the box 1 through the inlet 101 and passes through the middle of the inlet roller group 3, then winds around the guide roller group 401 group 4 from bottom to top, and finally passes through the middle of the outlet roller group 5 and extends out through the outlet 102. After extending out of the box 1, the packaging film 1001 passes over the top of the filling machine from the rear of the filling machine, and is conveyed to the cutting unit and forming unit by the conveying roller on the filling machine to form a packaging bag with an opening. Then, the food is filled into the packaging bag by the filling machine. Before being conveyed to the filling machine, the packaging film 1001 is sterilized on both sides by the ultraviolet lamp 6 in the box 1, making the filling safer and effectively improving the hygiene and safety level.

[0029] Each group of guide rollers 401 includes two guide rollers 401, and the axes of the two guide rollers 401 are coplanar, and the coplanar plane is an inclined plane. The inclined planes on which the axes of the two guide rollers 401 near the feed roller group 3 and the two guide rollers 401 near the discharge roller group 5 are located are inclined downwards from front to back. In adjacent groups of guide rollers 401, the inclination directions of the inclined planes are opposite. This arrangement allows the packaging film 1001 to form a concave groove structure between adjacent groups of guide rollers 401 after passing through each group of guide rollers 401. The middle section is vertical, and the upper and lower ends are inclined sections that are inclined towards each other. This allows the vertical section to be irradiated by the front of the ultraviolet lamp 6, and the inclined section will also be irradiated by the ultraviolet lamp 6. Thus, during the conveying process of the packaging film 1001, it can be effectively sterilized by ultraviolet light.

[0030] The number of guide rollers 401 group 4 is 3 or 5.

[0031] Both the feed roller group 3 and the discharge roller group 5 include two rotating rollers, and the inclined planes on which the axes of the two rotating rollers are located are inclined upward from front to back.

[0032] Ultraviolet lamps 6 are also provided on the upper and lower sides of the box 1, corresponding to the guide rollers 401 group 4.

[0033] The distance between the UV lamp 6 and the packaging film 1001 is 10-30cm.

[0034] The feed roller, guide roller 401, and discharge roller are all connected to the side wall of the housing 1 via bearings. One end of each feed roller, guide roller 401, and discharge roller extends out of the housing 1 and is connected to a gear. Corresponding gears in each feed roller group 3, discharge roller group 5, and guide roller group 401 are meshed together. A motor 12 is fixedly connected to one of the feed rollers, discharge rollers, or guide rollers 401 in each feed roller group 3, discharge roller group 5, and guide roller group 401 on the outside of the housing 1. The output shaft of the motor 12 is fixedly connected to the corresponding feed roller, guide roller 401, or discharge roller. In this embodiment, the motor 12 is a geared motor 12. In this embodiment, a shield 11 is fixedly attached to one side of the housing 1 to cover the gear and provide protection. The motor 12 is fixedly attached to the outside of the shield 11. Through the meshing action of the motor 12 and the gear, the feeding roller group 3, the guide roller group 401, and the discharge roller group 5 are driven to rotate synchronously.

[0035] There are two doors 2, and their outer ends are hinged to the side wall of the housing 1. One door 2 has a protruding limiting strip 201 on its inner front side, and the other door 2 has an L-shaped limiting groove 202 corresponding to the limiting strip 201 on its inner front side. When both doors 2 are closed, the limiting strip 201 engages with the limiting groove 202. A sealing strip is adhered to the contact point between the front opening of the housing 1 and the door 2. Magnetic blocks are embedded in the rear side of the limiting strip 201 and in the limiting groove 202, with opposite magnetic properties. The two doors 2 are magnetically attracted together by these blocks. In this embodiment, the sealing strip and magnetic blocks ensure that the doors 2 fit tightly against the housing 1 when closed, preventing gaps and thus preventing ultraviolet light from escaping through them. In this embodiment, a handle is also provided on the front side of the doors 2.

[0036] A support frame 7 is provided at the front of the housing 1. The support frame 7 includes a base plate 701. Two opposing support plates 702 are fixedly connected to the upper side of the base plate 701. A feeding roller 8 is connected between the two support plates 702. Two vertical plates 703 are also fixedly connected to the upper side of the base plate 701 behind the support plates 702. An auxiliary roller group 9 is connected between the two vertical plates 703. The auxiliary roller group 9 includes two longitudinally distributed auxiliary rollers and is aligned with the feed inlet 101 and the feed roller group 3. In this embodiment, the auxiliary rollers are rotatably connected between the two vertical plates 703 by bearings. A U-shaped groove is provided on the upper side of the support plate 702. Bearing seats are connected to both ends of the feeding roller 8 by bearings. The bearing seats overlap in the U-shaped groove, and the outer side of the bearing seats is fixed to the outer wall of the support plate 702 by bolts. In this embodiment, multiple strip-shaped mounting holes are evenly provided on both sides of the base plate 701. The support frame 7 is fixed to the mounting position by the cooperation of fixing pins with the mounting holes.

[0037] In this embodiment, connecting edges 103 are horizontally fixed to the bottom of both sides of the box 1. Multiple strip-shaped fixing holes are provided on the connecting edges 103. The box 1 is fixed in the corresponding installation position by the cooperation of the fixing pin and the fixing hole, so as to ensure that the position of the box 1 remains unchanged during the production process.

[0038] In this embodiment, the feed inlet 101 and the discharge outlet 102 are relatively narrow, and a feed roller group 3 is set near the feed inlet 101 and a discharge roller group 5 is set near the discharge outlet 102 to further shield the feed inlet 101 and the discharge outlet 102 to minimize the transmission of ultraviolet light from the feed inlet 101 and the discharge outlet 102.

[0039] In this embodiment, sterilization is performed using an ultraviolet lamp 6. Controlling the irradiation dose and duration is common knowledge that can be grasped by those skilled in the art, so it will not be described in detail here.

[0040] The working process of this embodiment is as follows:

[0041] A packaging film roll 10 is installed on the feeding roller 8. The packaging film 1001 extends from the packaging film roll 10 and passes through the auxiliary roller group 9 into the feed port 101, thus entering the box body 1. Inside the box body 1, after passing through the feeding roller group 3, it sequentially winds around multiple guide roller groups 401 4 from bottom to top, and then passes through the discharge roller group 5, finally exiting from the discharge port 102. The feeding roller group 3, guide roller group 401 4, and discharge roller group 5 are driven to rotate synchronously by the motor 12, and the rotation direction of each feeding roller, guide roller 401, and discharge roller is the conveying direction of the packaging film 1001. During the conveying process of the packaging film 1001, ultraviolet light lamp 6 is used to irradiate the packaging film 1001 to sterilize both sides.

[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
