[0001] This utility model belongs to the technical field of biodegradable plant fiber tableware production equipment, specifically relating to a disinfection and sterilization device for the production of biodegradable plant fiber tableware lunch boxes. Background Technology

[0002] The purpose of tableware disinfection is to ensure that all diners use truly clean tableware, avoid the impact of residue on our eating experience, and prevent cross-infection of germs. Tableware disinfection equipment refers to equipment used to clean and disinfect tableware that people normally use, such as bowls, chopsticks, spoons, plates, lunch boxes, cups, etc., such as dishwashers, dryers, and disinfection cabinets.

[0003] The patent application "CN217040817U" describes a disinfection device for producing biodegradable tableware, including a cabinet. A left positioning rod is fixedly installed on the top of the cabinet, and a left lamp holder is fixedly installed at the bottom of the left positioning rod. A left lamp tube is fixedly installed on the left side of the left lamp holder. A right positioning rod is fixedly installed on the top of the cabinet, and a right lamp holder is fixedly installed at the bottom of the right positioning rod. A right lamp tube is fixedly installed on the left side of the right lamp holder. A conveyor device is fixedly installed on the left side of the cabinet. The conveyor device includes a left crossbar, and a left driven wheel is movably installed on the left side of the left crossbar.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1

[0040] Please see Figures 1-5 The present invention provides the following technical solution:

[0041] A sterilization and disinfection device for the production of biodegradable plant fiber tableware and lunch boxes includes:

[0042] The disinfection box 1 is equipped with a feeding conveyor belt 10 and a discharging conveyor belt 11. A feeding support plate 12 is fixedly connected to the front end of the disinfection box 1. Two fans 9 are fixedly connected to the front end of the disinfection box 1. An ozone generator 6 and two telescopic rods 7 are fixedly connected to the top of the disinfection box 1. The outlet port of the ozone generator 6 and the telescopic ports of the two telescopic rods 7 are connected to the inner wall of the top of the disinfection box 1. A spring 14 is fixedly connected inside the disinfection box 1. An ultraviolet disinfection lamp group 15 is fixedly connected to the bottom end of the spring 14. A first motor 5 is fixedly connected to one side of the disinfection box 1. Protective covers 16 are fixedly connected to the telescopic ends of the two telescopic rods 7.

[0043] It also includes two sets of clamping mechanisms, both of which are located on the upper side of the discharge conveyor belt 11. The two sets of clamping mechanisms are used to clamp the tableware and lunch boxes.

[0044] In a specific embodiment of this utility model, the feeding conveyor belt 10 is responsible for transporting the biodegradable plant fiber tableware boxes to be disinfected and sterilized from the outside to the inside of the disinfection box 1, realizing automatic feeding of tableware boxes, replacing manual handling, improving production efficiency, and ensuring that the order and position of tableware boxes entering the disinfection box 1 are relatively stable.

[0045] After the tableware and lunch boxes have been disinfected and sterilized, the discharge conveyor belt 11 transports them from inside the disinfection box 1 to the outside, completing the entire disinfection process, realizing continuous production of tableware and lunch boxes, connecting with subsequent processes, and ensuring the smooth operation of the production line.

[0046] The feeding support plate 12 is fixedly connected to the front end of the disinfection box 1, providing stable support for the feeding conveyor belt 10, enhancing the stability of the feeding conveyor belt 10 installation, preventing the feeding conveyor belt 10 from shaking or shifting during the conveying of tableware and lunch boxes, and ensuring that the tableware and lunch boxes enter the disinfection box 1 smoothly and accurately for disinfection and sterilization.

[0047] Two fans 9 are installed at the front end of the disinfection chamber 1. By blowing air into the disinfection chamber 1, the air flow inside the chamber is accelerated. On the one hand, this helps ozone to diffuse evenly inside the disinfection chamber 1, improving the coverage and effectiveness of ozone disinfection of tableware and lunch boxes. On the other hand, it promotes hot air circulation, which, together with the subsequent heating device, accelerates the evaporation of moisture on the surface of tableware and lunch boxes, achieving drying treatment. At the same time, it reduces the humidity inside the disinfection chamber 1, creating a good environmental condition for disinfection and sterilization.

[0048] Ozone generator 6 is fixedly connected to the top of disinfection chamber 1 and communicates with the inner wall of the top of disinfection chamber 1 through the gas outlet. It can generate ozone gas with strong oxidizing properties. After entering the interior of disinfection chamber 1, ozone can react with bacteria, viruses, fungi and other microorganisms on the surface and inside of tableware and food containers, destroying the cell structure and physiological activity of microorganisms, thereby achieving the purpose of efficient sterilization and disinfection. It works in synergy with ultraviolet disinfection lamp group 15 to improve the overall disinfection and sterilization effect.

[0049] Two telescopic rods 7 are fixed at the top of the disinfection box 1, and their telescopic ports are connected to the inner wall of the top of the disinfection box 1. Their telescopic function can adjust the height of connecting parts such as the protective cover 16 inside the disinfection box 1. During equipment installation, commissioning, or maintenance, the position of relevant parts can be flexibly adjusted for easy operation and repair. In actual production, the height of the protective cover 16 can be adjusted according to the size of tableware and lunch boxes of different specifications and heights to better adapt to the size of the tableware and lunch boxes and ensure the disinfection and sterilization effect.

[0050] One end of the spring 14 is fixed inside the disinfection box 1, and the other end is connected to the ultraviolet disinfection lamp assembly 15, serving as a buffer and shock absorber. During the operation of the ultraviolet disinfection lamp assembly 15, it can reduce the impact of vibrations generated by the equipment operation on the ultraviolet disinfection lamp assembly 15, preventing the lamp tubes from being damaged by vibration; at the same time, when tableware and food containers collide slightly with the ultraviolet disinfection lamp assembly 15 during transportation, the elastic deformation of the spring 14 can absorb the collision energy, preventing the ultraviolet disinfection lamp assembly 15 from being subjected to hard impacts and protecting its normal operation.

[0051] The ultraviolet disinfection lamp assembly 15 emits ultraviolet light to destroy the DNA or RNA structure of microorganisms, rendering them unable to reproduce and survive, thereby disinfecting and sterilizing biodegradable plant fiber tableware containers. The connection of the spring 14 allows the ultraviolet disinfection lamp assembly 15 to have a certain amount of room to move, adapting to changes in the shape and position of the tableware containers within a certain range, ensuring that ultraviolet light can irradiate as much of the surface of the tableware containers as possible, reducing disinfection dead spots and improving the disinfection effect.

[0052] The first motor 5 is fixedly connected to one side of the sterilization box 1, providing power to related components such as the transmission mechanism, the feeding conveyor belt 10, or the discharging conveyor belt 11. The rotation of the motor drives the connected transmission components, enabling functions such as the transport of tableware and food containers and the movement of internal components. Its speed and torque can be adjusted according to production needs, ensuring the stability and reliability of the equipment operation and meeting the requirements of different production conditions.

[0053] The protective cover 16 is fixedly connected to the telescopic end of the telescopic rod 7. It is mainly used to protect key components inside the disinfection box 1, such as the air outlet of the ozone generator 6 and the telescopic part of the telescopic rod 7, to prevent tableware and lunch boxes from colliding with these components during transportation and causing damage. At the same time, it can prevent external debris, dust and other objects from entering these key parts, affecting the normal operation of the equipment and the disinfection and sterilization effect. In addition, the protective cover 16 can also prevent ozone and other disinfection gases from leaking to a certain extent, ensuring the safety of operators and the hygiene of the working environment.

[0054] Two clamping mechanisms are located on the upper side of the discharge conveyor belt 11, mainly used to clamp the tableware containers. When the tableware containers have completed sterilization and are about to leave the sterilization chamber 1, the clamping mechanisms activate, firmly holding the containers in place. Their functions are: first, to ensure the stability of the tableware containers on the discharge conveyor belt 11, preventing shaking or shifting during transport that could affect subsequent processes such as packaging and stacking; second, to provide some shaping for the tableware containers, making them more regular in shape, facilitating subsequent storage and transportation; and third, to act as a buffer during the discharge process, preventing damage from excessive discharge speed or collisions, thus improving product quality and production safety.

[0055] It should be noted that the specific models of the intelligent controller 2, humidity sensor 3, temperature sensor 4, second motor 17, ultraviolet disinfection lamp group 15, and first motor 5 used shall be selected by those skilled in the art. Furthermore, the intelligent controller 2, humidity sensor 3, temperature sensor 4, second motor 17, ultraviolet disinfection lamp group 15, and first motor 5 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0056] Please refer to the details. Figures 1-5 One set of clamping mechanisms includes:

[0057] Drive rod 21, drive rod 21 is rotatably connected to the inner walls of both sides of one of the protective covers 16;

[0058] Two drive gears 22 are provided, and both drive gears 22 are fixedly connected to the circumferential surface of the drive rod 21.

[0059] There are two transmission rods 20, and the two transmission rods 20 are rotatably connected to the inner walls of both sides of one of the protective covers 16.

[0060] There are four semi-transmission gears 19, which are fixedly connected to the circumferential surfaces of the two transmission rods 20 respectively, and the four semi-transmission gears 19 mesh with the two drive gears 22 respectively.

[0061] Four arc-shaped clamping blocks 18 are provided, and the four arc-shaped clamping blocks 18 are respectively fixedly connected to the circumferential surface of the two transmission rods 20.

[0062] The second motor 17 is fixedly connected to one side of the protective cover 16, and the output end of the second motor 17 is fixedly connected to one end of the drive rod 21.

[0063] The positioning disinfection component is located on the upper side of the feeding conveyor belt 10. The positioning disinfection component is used to position the tableware and work with the ultraviolet disinfection lamp group 15 to continuously disinfect it.

[0064] In this embodiment: when the biodegradable plant fiber tableware container is conveyed to the disinfection area inside the disinfection box 1 via the feeding conveyor belt 10, the intelligent controller 2 starts the second motor 17 according to the preset program. The output shaft of the second motor 17 drives the drive rod 21 to rotate, and the two drive gears 22 fixed on the drive rod 21 rotate synchronously.

[0065] The drive gear 22 meshes with the half-drive gear 19, transmitting rotational motion to the transmission rod 20, causing the transmission rod 20 to rotate around its own axis. Since the four half-drive gears 19 are respectively fixed on the two transmission rods 20 and mesh with the two drive gears 22, the two transmission rods 20 rotate synchronously, causing the four arc-shaped clamps 18 fixed on them to move synchronously towards the center.

[0066] As the arc-shaped clamping blocks 18 rotate, they gradually approach and encircle the tableware container, forming a clamping force that firmly fixes the tableware container at a predetermined position on the feeding conveyor belt 10. At this time, the convex clamping blocks 25 in the positioning and disinfection assembly, driven by the reciprocating screw 24, further position and clamp the tableware container, ensuring that the tableware container remains stable during the disinfection process.

[0067] With the tableware container clamped and secured, the ultraviolet disinfection lamp assembly 15 operates continuously, providing comprehensive ultraviolet disinfection. Because the tableware container is in a stable position, the ultraviolet light can evenly irradiate all surfaces of the container, effectively killing bacteria, viruses, fungi, and other microorganisms.

[0068] Once the tableware and food container have completed the sterilization process, the intelligent controller 2 issues a command to control the second motor 17 to reverse. The drive rod 21 then rotates in the opposite direction, causing the drive gear 22 and the half-transmission gear 19 to mesh in the opposite direction. This causes the transmission rod 20 to drive the arc-shaped clamping block 18 to rotate to both sides, releasing the clamping force on the tableware and food container.

[0069] Simultaneously, the convex clamping block 25 in the positioning and disinfection component also moves to both sides under the reverse rotation of the reciprocating screw 24, releasing the positioning and clamping of the tableware and lunch box. Driven by the feeding conveyor belt 10, the tableware and lunch box continues to move forward, entering other disinfection areas inside the disinfection box 1 or being sent out of the disinfection box 1 via the discharging conveyor belt 11, completing the entire disinfection process.

[0070] Please refer to the details. Figures 1-3 The positioning disinfection component includes:

[0071] The reciprocating screw 24 is rotatably connected to the inside of both sides of the disinfection box 1, and the reciprocating screw 24 is fixedly connected to the telescopic end of the first motor 5;

[0072] Limiting rod 23 is fixedly connected to the inside of both sides of the disinfection box 1;

[0073] Nut 26, there are two nuts 26, both nuts 26 are threaded to the circumferential surface of the reciprocating lead screw 24;

[0074] Two convex clamping blocks 25 are provided. The two convex clamping blocks 25 are fixedly connected to the circumferential surfaces of the two nuts 26 respectively. The two convex clamping blocks 25 are slidably connected to the circumferential surfaces of the two limit rods 23 respectively. The bottom of the two convex clamping blocks 25 is a tough plastic end.

[0075] In this embodiment: when the biodegradable plant fiber tableware container is conveyed to the area below the positioning and disinfection component via the feeding conveyor belt 10, the control system starts the first motor 5. The telescopic end of the first motor 5 drives the reciprocating lead screw 24 to rotate. Since the two nuts 26 are threaded onto the reciprocating lead screw 24, and under the guidance and restriction of the limiting rod 23, the nuts 26 cannot rotate with the lead screw, but can only move along the axial direction of the reciprocating lead screw 24.

[0076] As the reciprocating screw 24 rotates, the two nuts 26 move toward each other on the screw, and the convex clamping blocks 25 fixed to the circumferential surface of the nuts 26 move toward the center in sync. When the convex clamping block 25 contacts the tableware container, its bottom flexible plastic end fits tightly against the surface of the tableware container and applies a certain clamping force, firmly clamping the tableware container at a predetermined position on the feeding conveyor belt 10.

[0077] At this time, the ultraviolet disinfection lamp group 15 continues to work. Since the tableware container has been accurately positioned, the ultraviolet light can evenly and comprehensively irradiate the surface of the tableware container, achieving efficient disinfection and sterilization. After the tableware container completes the disinfection stage, the control system controls the first motor 5 to reverse, the reciprocating screw 24 to rotate in the opposite direction, and the two nuts 26 drive the convex clamps 25 to move to both sides, releasing the tableware container.

[0078] The tableware and lunch boxes continue to move forward under the drive of the feeding conveyor belt 10, enter the ozone disinfection area inside the disinfection box 1, complete the subsequent disinfection and sterilization process, and then are sent out of the disinfection box 1 via the discharge conveyor belt 11.

[0079] Please refer to the details. Figure 2 The disinfection box 1 is fixedly connected to one side of an intelligent controller 2, a humidity sensor 3, and a temperature sensor 4.

[0080] In this embodiment, the intelligent controller 2, humidity sensor 3, and temperature sensor 4 are fixedly connected to one side of the disinfection chamber 1, forming the intelligent control and environmental monitoring system for the entire disinfection and sterilization device. The humidity sensor 3 and temperature sensor 4 monitor the humidity and temperature data inside the disinfection chamber 1 in real time and transmit the data to the intelligent controller 2 in the form of electrical signals. The intelligent controller 2 is pre-set with a suitable humidity and temperature range for the disinfection and sterilization of biodegradable plant fiber tableware and lunch boxes. After receiving the sensor data, it analyzes and processes the data.

[0081] Please refer to the details. Figures 1-5 An infrared sensor 13 is fixedly connected to one inner wall of the disinfection box 1, and a feeding support plate 12 is fixedly connected to the front end of the disinfection box 1.

[0082] In this embodiment: the feeding support plate 12 is fixedly connected to the front end of the sterilization box 1, providing a stable support platform for the feeding conveyor belt 10 and ensuring that the tableware and lunch boxes are transported smoothly on the feeding conveyor belt 10. The infrared sensor 13 is fixedly installed on one side of the inner wall of the sterilization box 1, and its sensing area covers the tableware and lunch box transport path above the feeding conveyor belt 10.

[0083] Please refer to the details. Figures 1-3 The disinfection box 1 has a movable card with a plastic acrylic sleeve 8.

[0084] In this embodiment, the plastic acrylic sleeve 8 is movably attached inside the disinfection chamber 1. Its excellent wear resistance, corrosion resistance, and light transmittance allow it to play multiple roles during device operation. In the ultraviolet disinfection process, the plastic acrylic sleeve 8 serves as the protective outer shell of the ultraviolet disinfection lamp assembly 15. It not only isolates external dust and debris, preventing them from adhering to the surface of the ultraviolet disinfection lamp assembly 15 and affecting the irradiation effect, but also prevents corrosive gases such as ozone inside the disinfection chamber 1 from directly contacting the lamp tubes, thus extending the lamp tubes' lifespan.

[0085] The working principle and usage process of this utility model are as follows: First, the tableware and lunch boxes to be disinfected are placed on the feeding conveyor belt 10. Under the stable support of the front feeding support plate 12, the feeding conveyor belt 10 smoothly transports the tableware and lunch boxes into the disinfection box 1. When the tableware and lunch boxes reach the bottom of the positioning disinfection component, the first motor 5 starts, which drives the reciprocating screw 24 to rotate. Under the guidance of the limit rod 23, the nut 26 drives the convex clamping block 25 to move towards the center, using the bottom flexible plastic end to clamp the tableware and lunch boxes. At the same time, the intelligent controller 2 starts the second motor 17, which drives the drive rod 21 to rotate and drive the drive gear 22. Through the meshing with the half transmission gear 19, the transmission rod 20 drives the arc-shaped clamping block 18 to hug and clamp the tableware and lunch boxes, completing the positioning and clamping operation. Subsequently, the ultraviolet disinfection lamp group 15 starts working under the buffer protection of the spring 14. It uses ultraviolet light to destroy the structure of microorganisms for preliminary disinfection. At the same time, the ozone generated by the ozone generator 6 is evenly diffused under the action of the fan 9 accelerating the air flow, and reacts with the microorganisms to enhance the disinfection effect in conjunction with the ultraviolet light. During this process, humidity sensor 3 and temperature sensor 4 monitor the environmental data inside the chamber in real time and transmit it to intelligent controller 2. If the temperature and humidity exceed the preset range, intelligent controller 2 controls the relevant equipment to make adjustments. After disinfection is completed, intelligent controller 2 controls the second motor 17 and the first motor 5 to reverse, causing the arc-shaped clamp 18 and the convex clamp 25 to release, and the tableware and lunch boxes are sent out of the disinfection chamber 1 by the discharge conveyor belt 11, completing the entire disinfection process.

[0086] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
