Description

Technical Field

[0001] This utility model belongs to the field of lunch box processing technology, specifically a sterile disinfection device for processing plastic lunch boxes. Background Technology

[0002] Plastic lunch boxes are a type of food packaging container widely used in modern catering. They are lightweight, low-cost, and have good sealing properties, and are commonly used in takeout, fast food, and cooked food.

[0003] In the production and processing of plastic lunch boxes, plastic granules are usually dried, mixed, and then melted in an extruder. The molten plastic is injected into a mold and cooled under high pressure to form the main body of the lunch box. After the lunch box is formed, it is trimmed and sterilized. When sterilizing plastic lunch boxes, they are first placed in a sterilization device. Ultraviolet lamps are installed on the side wall of the device to sterilize the surface of the plastic lunch box by ultraviolet irradiation.

[0004] Traditional plastic lunchbox sterilizers typically have UV lamps fixed inside the device. The UV rays travel in a straight line and sterilize the lunchboxes by directly irradiating their surface. Since plastic lunchboxes are usually arranged in multiple rows, areas not directly irradiated can easily become sterilization dead zones, resulting in uneven sterilization and reduced sterilization effectiveness and efficiency.

[0005] Therefore, this utility model provides a sterile disinfection device for processing plastic lunch boxes. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 6As shown in the figure, an aseptic disinfection device for processing plastic lunch boxes according to an embodiment of the present invention includes a disinfection box 1; multiple anti-slip legs 10 are fixedly connected to the bottom of the disinfection box 1; a sealed door 11 is installed on the side wall of the disinfection box 1; a glass plate 12 is fixedly connected to the middle of the sealed door 11; a control panel 13 is installed in the middle of the sealed door 11; a placement assembly 3 is provided on the inner side wall of the disinfection box 1; multiple placement mesh plates 14 are installed in the middle of the placement assembly 3; two sets of disinfection lamps 15 are installed on the inner side wall of the disinfection box 1; the two sets of disinfection lamps 15 are arranged opposite each other; a rotating assembly 2 is provided between the two sets of disinfection lamps 15 and the disinfection box 1; an exhaust assembly 4 and a recycling assembly 5 are installed in the middle of the disinfection box 1; the rotating assembly 2 includes two adjusting boxes 21; the two adjusting boxes 21 are fixedly connected to the inner side wall of the disinfection box 1; the two... An adjusting box 21 is arranged opposite to each other; a reciprocating screw 22 is rotatably connected to the middle of the adjusting box 21; a square nut 23 is installed in the middle of the reciprocating screw 22; the end of the square nut 23 passes through one end of the adjusting box 21; a driver 24 is fixedly connected to the end of the reciprocating screw 22; a connecting plate 20 is fixedly connected to the side wall of the square nut 23; an adjusting plate 25 is fixedly connected to the end of the connecting plate 20; a toothed groove 26 is opened on the side wall of the adjusting plate 25; two fixing rods 27 are fixedly connected to the inner side wall of the disinfection box 1; a support plate 28 is fixedly connected to the end of the two fixing rods 27; multiple gears 29 are rotatably connected to the bottom of the support plate 28; the gears 29 and the toothed groove 26 are meshed; a disinfection lamp 15 is installed at the bottom of the gear 29; the end of the disinfection lamp 15 is rotatably connected to the bottom of the disinfection box 1; when working, the sealed box door 11 is opened. After starting, install multiple placement mesh plates 14 in the placement assembly 3 according to the height of the plastic lunch boxes. Place the plastic lunch boxes on the placement mesh plates 14, close the sealed door 11, and turn on the equipment through the control panel 13 to allow the disinfection lamp 15 to irradiate ultraviolet light onto the surface of the plastic lunch boxes. At the same time, control the driver 24 to turn on, causing the output end of the driver 24 to drive the reciprocating screw 22 to rotate in the middle of the adjusting box 21. At this time, the square nut 23 drives the connecting plate 20 to move in the middle of the reciprocating screw 22. The end of the connecting plate 20 drives the adjusting plate 25 to move. When the square nut 23 moves to the end of the adjusting box 21, it moves in the other direction. As the output end of the driver 24 rotates, the square nut 23 reciprocates in the middle of the reciprocating screw 22. The toothed groove 26 in the middle of the adjusting plate 25 drives multiple teeth. The wheel 29 rotates left and right, causing the disinfection lamp 15 to swing left and right via the gear 29. As a result, the irradiation range of the disinfection lamp 15 expands with the swing. The hot air is evenly discharged to the surface of each layer of plastic lunch boxes through the exhaust component 4. The heat recovery component 5 recovers and reuses the heat from the bottom of the disinfection box 1. Through the above structure, the continuous swing of the disinfection lamp 15 during the disinfection process can dynamically cover all surfaces of the lunch box, reducing the disinfection blind spots caused by the fixed irradiation of the disinfection lamp 15 on the edges, grooves or overlapping parts of the plastic lunch box. It can expand the single irradiation area, effectively improve the uniformity of disinfection of the plastic lunch box by the disinfection lamp 15, reduce disinfection dead corners, and effectively reduce the problem of local overheating caused by the disinfection lamp 15 irradiating the same area for a long time, which can lead to deformation or aging of the lunch box.

[0026] like Figure 2 , Figure 3 and Figure 5 As shown, two sets of fixing plates 31 are fixed to the inner wall of the disinfection box 1; the two sets of fixing plates 31 are respectively set on both sides of the disinfection box 1; multiple V-shaped blocks 32 are fixed to the middle of the fixing plates 31; the multiple V-shaped blocks 32 are equidistantly distributed; two elastic plates 33 are fixed to the inner wall of the V-shaped blocks 32; the two elastic plates 33 are arc-shaped; the two elastic plates 33 are arranged opposite each other; two sets of mounting rods 34 are fixed to the ends of the placement mesh plate 14; during operation, when different sized lunch boxes need to be disinfected, the placement mesh plate 14 is placed at a specified height, and the mounting rods 34 at both ends of the placement mesh plate 14 correspond to the positions of the V-shaped blocks 32 at the specified height. The mounting rod 34 moves downwards through two elastic plates 33. When the mounting rod 34 passes through the elastic plates 33, it applies pressure, causing the elastic plates 33 to bend elastically. The mounting rod 34 enters the bottom of the V-shaped block 32, and the V-shaped block 32 quickly fixes the mounting rod 34 in place, thereby adjusting the number and spacing of the placement mesh plates 14. The above structure allows the placement mesh plates 14 to be flexibly adjusted between different height layers, enabling the simultaneous disinfection of multiple sizes of lunch boxes in the same equipment. This reduces the stacking of lunch boxes inside the disinfection box 1 or the excessive spacing, effectively reducing the problems of incomplete local disinfection or wasted space.

[0027] like Figure 2 and Figure 6 As shown, the exhaust assembly 4 includes a hot air box 41; the hot air box 41 is installed on the top of the disinfection box 1; a connecting pipe 42 is fixedly connected to the middle of the hot air box 41; a first exhaust pipe 43 is fixedly connected to the end of the connecting pipe 42; the first exhaust pipe 43 is arc-shaped; the first exhaust pipe 43 is fixedly connected to the inner wall of the disinfection box 1; several exhaust slots 44 are opened in the middle of the first exhaust pipe 43; during operation, in the disinfection process, the hot air box 41 is opened, and the hot air inside the hot air box 41 enters the first exhaust pipe 43 through the connecting pipe 42, and the hot air inside the first exhaust pipe 43 flows through... The hot air is discharged through several exhaust ducts 44 and blown onto the surface of each layer of plastic lunch boxes, so that the hot air is discharged evenly. Through the combined use of heat flow and ultraviolet irradiation, the microorganisms on the surface of the plastic lunch boxes are quickly killed. The above structure can uniformly heat the inside of the disinfection box 1 while the disinfection lamp 15 irradiates ultraviolet light to disinfect the lunch boxes, thereby accelerating the disinfection efficiency of the lunch boxes. In addition, the exhaust ducts 44 in the middle of the first exhaust pipe 43 can spray from different heights, effectively covering all positions of the lunch boxes and the gaps between layers, reducing the temperature difference between the upper and lower layers, and improving the disinfection effect and efficiency.

[0028] like Figure 2 , Figure 5 and Figure 6As shown, the recycling component 5 includes a channel 51; the channel 51 is located at the bottom of the disinfection box 1; a fan 52 is installed in the middle of the channel 51; a protective cover 53 is fixedly connected to the bottom of the disinfection box 1; the protective cover 53 is positioned corresponding to the channel 51; a second exhaust duct 54 is fixedly connected to the middle of the protective cover 53; a heating wire 55 is fixedly connected to the middle of the second exhaust duct 54; the end of the second exhaust duct 54 is fixedly connected to the middle of the connecting pipe 42; during operation, the fan 52 is turned on, the fan blades in the fan 52 rotate at high speed, and the hot airflow disinfects the plastic lunch box inside the disinfection box 1, and then the residual heat is drawn in by the fan 52. The heat enters the second exhaust duct 54 through the protective cover 53. At the same time, the heating wire 55 is turned on. The surface temperature of the heating wire 55 gradually rises and is transferred to the surface of the second exhaust duct 54. The waste heat is reheated and then enters the connecting pipe 42 and is discharged back into the disinfection box 1, thereby recovering and utilizing the waste heat. Through the above structure, the direct discharge of waste heat into the environment during the disinfection process can be reduced, thus reducing the energy waste caused by the direct loss of heat into the environment. The recovered waste heat is reheated and then discharged back into the disinfection box 1 for reuse, reducing the energy consumption required for continuous heating.

[0029] like Figure 5 and Figure 6 As shown, a filter screen 6 is fixedly connected to the middle of both the through groove 51 and the exhaust groove 44; the filter screen 6 is fixedly connected to one side of both the through groove 51 and the exhaust groove 44; during operation, during the disinfection process, the residue inside the disinfection box 1 is intercepted by the filter screen 6 during the airflow. The above structure can effectively reduce the amount of residue entering the first exhaust duct 43 and the through groove 51 during the disinfection process, reduce the amount of residual impurities entering the first exhaust duct 43 and the second exhaust duct 54 and causing wear or blockage to the inner wall of the pipes, and maintain smooth airflow.

[0030] like Figure 2 and Figure 5 As shown, a heat insulation cover 7 is fixedly connected to the middle of the second exhaust duct 54; the heat insulation cover 7 is set outside the heating wire 55; when working, when the heating wire 55 is turned on to heat the airflow inside the second exhaust duct 54, the heat insulation cover 7 isolates the heating wire 55 from the outside air. The above structure can reduce the forced heat exchange between the heat generated on the surface of the heating wire 55 and the outside air, maintain the temperature of the heating wire 55 when heating the second exhaust duct 54, and reduce heat loss.

[0031] During operation, after opening the sealed door 11, multiple placement mesh plates 14 are installed in the placement assembly 3 according to the height of the plastic lunch boxes. The plastic lunch boxes are placed on the placement mesh plates 14. The sealed door 11 is closed, and the equipment is turned on through the control panel 13, allowing the disinfection lamp 15 to irradiate ultraviolet light onto the surface of the plastic lunch boxes. At the same time, the driver 24 is turned on, causing the output end of the driver 24 to drive the reciprocating screw 22 to rotate in the middle of the adjusting box 21. At this time, the square nut 23 drives the connecting plate 20 to move in the middle of the reciprocating screw 22. The end of the connecting plate 20 drives the adjusting plate 25 to move. When the square nut 23 moves to the end of the adjusting box 21, it moves in the other direction. When the output end 24 rotates, the square nut 23 moves back and forth in the middle of the reciprocating screw 22. The toothed groove 26 in the middle of the adjusting plate 25 drives multiple gears 29 to rotate left and right. The gears 29 cause the disinfection lamp 15 to swing left and right, so the irradiation amplitude of the disinfection lamp 15 increases with the swing. The hot air is evenly discharged to the surface of each layer of plastic lunch boxes through the exhaust assembly 4. The heat recovery assembly 5 recovers and reuses the heat from the bottom of the disinfection box 1. When lunch boxes of different sizes need to be disinfected, the placement mesh plate 14 is placed at the specified height. The mounting rods 34 at both ends of the placement mesh plate 14 correspond to the V-shaped blocks 32 at the specified height. The mounting rods 34 move downward through two elastic plates 33. When the mounting rod 34 passes the elastic plate 33, it applies pressure, causing the elastic plate 33 to bend elastically. The mounting rod 34 then enters the bottom of the V-block 32, which quickly fixes the mounting rod 34 in place. This allows for adjustment of the number and spacing of the mesh plates 14. During the disinfection process, the hot air box 41 is turned on, and the hot air flow inside the hot air box 41 enters the first exhaust duct 43 through the connecting pipe 42. The hot air flow inside the first exhaust duct 43 is discharged through several exhaust slots 44 and blown onto the surface of each layer of plastic lunch boxes, ensuring even distribution of the hot air flow. Through the combined use of heat flow and ultraviolet irradiation, microorganisms on the surface of the plastic lunch boxes are quickly killed. The fan 52 is then turned on. The fan blades in section 2 rotate at high speed. After the hot airflow disinfects the plastic lunch box inside the disinfection box 1, the residual heat is drawn in by the fan 52 and enters the second exhaust duct 54 through the protective cover 53. At the same time, the heating wire 55 is turned on. The surface temperature of the heating wire 55 gradually rises and is transferred to the surface of the second exhaust duct 54. The residual heat is reheated and then enters the connecting pipe 42 and is discharged back into the disinfection box 1, thus recovering and utilizing the residual heat. During the disinfection process, the residue inside the disinfection box 1 is intercepted by the filter screen 6 during the airflow. When the heating wire 55 is turned on to heat the airflow inside the second exhaust duct 54, the heat insulation cover 7 isolates the heating wire 55 from the outside air.
