In the production process of food plastic boxes, safety and non-toxicity are the most important production and use standards, so it is very necessary to disinfect food plastic boxes;

[0003] In the prior art, the disinfection devices used for the production of degradable food plastic boxes mostly place stacked plastic boxes together in a disinfection cabinet for disinfection. Due to the stacking of the boxes, part of the box surface cannot be fully disinfected, and due to the single disinfection method, a good disinfection effect cannot be ensured. Therefore, we propose a conveying and disinfection device for the production of degradable food plastic boxes. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a conveying and disinfecting device for the production of degradable plastic food boxes, which has a reliable conveying and disinfecting unit, facilitates the loading process, and has a dual disinfection effect: the runway conveyor drives the vertical hanging arm and the cage placed below to move cyclically around the supporting frame, so that the loading can be carried out at the cage placed on the outside, and high-temperature fumigation, water control and drying operations are carried out in sequence; the steam sprayer sprays water vapor upward, and the high-temperature water vapor rises upward and fully contacts the inside of the plastic food box, thereby effectively achieving a disinfection effect, the blower blows wind upward, the electric heating wire heats the blown wind, and then the plastic food box is quickly dried by hot air, and in the hot air drying process, it can achieve a second disinfection effect, and it also has a recycling unit, which can collect water droplets condensed on the surface of the plastic food box to achieve water resource recycling, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a conveying and disinfecting device for the production of degradable food plastic boxes, comprising a support frame, a conveying and disinfecting unit and a recycling unit;

[0006] The supporting frame is a vertical T-shaped structure, and the enclosure frame is an inverted L-shaped structure. The enclosure frame is arranged on the right side of the supporting frame, and the two are fixedly connected by a bottom connecting plate;

[0007] Conveying and disinfection unit: comprising a runway conveyor, a vertical hanging arm, a placement cage, a wire mesh, a steam sprayer and a water supply port, the upper end of the support frame is fixedly installed with the runway conveyor, the upper horizontal end of the enclosure frame is stuck on the upper side of the runway conveyor, a plurality of downward vertical hanging arms are fixedly connected to the movable assembly of the runway conveyor, the lower end of the vertical hanging arm is fixedly connected to the middle part of the upper side of the placement cage, the placement cage is composed of upper and lower X-shaped frames and four vertical connecting rods at the corners, and a wire mesh is fixedly installed on the upper end of the lower X-shaped frame, a steam sprayer is installed on the front side of the middle area between the support frame and the enclosure frame, the spray end of the steam sprayer is facing upward, and a water supply port is fixedly connected to the upper right side of the steam sprayer;

[0009] The support frame is used for the installation of the runway conveyor. The runway conveyor drives the placement cage and the lunch box to move in a cycle through the vertical boom, so that loading can be carried out at the placement cage located on the outside. The food plastic box is inverted in the placement cage. The placed food plastic box bypasses the inside of the device and undergoes high-temperature fumigation, water control and drying operations in sequence. The wire mesh can support the food plastic box and allow the gas below to pass through. The steam sprayer sprays water vapor upward, and the high-temperature water vapor rises upward and fully contacts the inside of the food plastic box, thereby effectively achieving a disinfection effect. The water supply port is connected to an external water source through a socket pipe to supply water to the inside of the steam sprayer. The recycling unit collects the water droplets condensed on the surface of the food plastic box and recycles them into the steam sprayer, thereby achieving the effect of saving energy.

[0010] Furthermore, the transport and disinfection unit also includes a vertical slide bar, a lifting rod and a pressure plate. The vertical suspension arm is internally slidably connected with the vertical slide bar, the lower end of the vertical slide bar is fixedly connected to the center of the pressure plate, and the side of the vertical suspension arm is provided with a rectangular through hole. The lifting rod passes through the rectangular through hole horizontally and is fixedly connected to the vertical slide bar. The vertical slide bar pushes the pressure plate to press on the upper side of the food plastic box under the action of gravity, thereby fixing the food plastic box and ensuring the stability of the placement during transportation and fumigation; the vertical slide bar is lifted upward by the lifting rod, so that there is enough distance between the pressure plate and the bottom of the cage, thereby facilitating the loading process of the food plastic box, and the plastic box can be pressed and fixed by letting go.

[0011] Furthermore, the transport and disinfection unit further comprises a blower and an electric heating wire. The blower is fixedly mounted on the rear side of the middle area between the support frame and the enclosure frame, the air inlet of the blower faces backwards and the air outlet faces upwards, and an electric heating wire is mounted at the air outlet. The blower blows out wind upwards, and the electric heating wire heats the blown wind, thereby quickly drying the food plastic box with hot air, and during the hot air drying process, a second disinfection effect can be achieved.

[0012] Furthermore, the recycling unit includes a water collection box, a water pump and a connecting pipe. The water collection box is installed between the steam sprayer and the blower. The water pump is installed at the middle position of the lower right side of the enclosure frame. The output end of the water pump extends to the inner bottom of the water collection box. The water outlet of the water pump is connected to the internal water tank of the steam sprayer through the connecting pipe. When the cage rack containing the food plastic box is moved to the middle of the device and is located between the steam sprayer and the blower, the larger water droplets condensed on the surface of the food plastic box will fall down into the water collection box. The water pump passes the collected water into the internal water tank of the steam sprayer through the connecting pipe to achieve recycling.

[0013] Furthermore, the recycling unit further comprises a PLC controller and a water level detector, the PLC controller and the water level detector are installed on the upper side of the water pump, the detection end of the water level detector extends to the inner upper part of the water collection box, and the water level detector is bidirectionally electrically connected to the PLC controller, and the input end of the water pump is electrically connected to the output end of the external power supply through the PLC controller. The water level detector is used to detect the height of the water level inside the water collection box, so that after a certain amount of water is collected, the PLC controller controls the water pump to work according to the signal of the water level detector, and then transfers the collected water to the internal water tank of the steam sprayer.

[0014] Furthermore, it also includes an observation window and a control panel. The observation window is embedded in the middle of the right side of the enclosure frame, and the control panel is installed on the right side of the observation window. The input ends of the runway conveyor, steam sprayer, blower and heating wire are all electrically connected to the output end of the external power supply through the control panel. The observation window can conveniently observe the conveying and disinfection status of the food plastic box inside the device, so as to facilitate the control of the start and stop of each electrical device on the control panel.
