Description

Technical Field

[0001] This utility model relates to the technical field of self-heating rice sterilization equipment, specifically to a self-heating rice sterilization device. Background Technology

[0002] Self-heating rice is a type of self-heating food. It refers to pre-packaged food that does not rely on electricity or fire for heating, but is heated by its own heating pack. To use it, simply place the special heating pack at the bottom of the food container and add a cup of cold water to make steaming hot food. The self-heating rice comes with a heating pack that heats up when it comes into contact with water. The heating pack is mainly composed of materials such as iron powder, aluminum powder, coke, activated carbon, and quicklime. When cold water is added, it reacts and can reach a temperature of 150°C, with a steam temperature of 200°C. The maximum heat retention time can be maintained for three hours. In case of an accident, burns and other injuries are highly likely. Self-heating rice requires sterilization during production to ensure its safety and convenience for consumption. Patent number CN202222970827.8 discloses a sterilization device for self-heating rice, which allows for easy handling of the rice when the serving tray is removed from the sterilization chamber, avoiding hand exposure to the sterilization lamp. However, when using sterilization equipment, the limited surface area of ​​the serving tray slows down the sterilization process when there is a large quantity of rice. Therefore, we propose a self-heating rice sterilization device. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a self-heating rice sterilization device.

[0004] The technical solution adopted by this utility model to solve its technical problem is a self-heating rice sterilization device, including a body, a sterilizer body is assembled in the body, and a slide is slidably installed in the body. A sliding groove is opened on the side of the body near the slide, and there are two sets of sliding grooves. A sliding seat is integrally constructed on the outer wall surface of the slide, which fits into the sliding groove, and there are two sets of sliding seats. A screw rod is rotatably installed in the sliding groove and screwed to the sliding seat. A sprocket is assembled at the end of the screw rod located on the outside of the body. A chain for transmission is assembled between the two sets of sprockets.

[0005] A support plate is rotatably mounted on the top surface of the slide table, and a vertical shaft connected to the support plate is rotatably mounted inside the slide table. A worm gear is sleeved on the outer circumference of the vertical shaft, and a worm gear meshing with the worm gear is rotatably mounted inside the slide table. A reducer B connected to the worm gear is installed inside the slide table, and a servo motor is installed at the power input end of the reducer B. A material rack for holding self-heating rice is snapped onto the top surface of the support plate.

[0006] By adopting the above technical solution, when sterilizing self-heating rice using sterilization equipment, the self-heating rice can be conveniently placed on the material rack. Then, the screw in the slide groove inside the machine rotates, so that the screw can be screwed together with the slide block in the slide groove, causing the slide block to slide and move in the slide groove. Then, the slide block can easily drive the slide table to move, and the slide table can move the material rack into the machine body, so that the sterilizer body inside the machine body can operate and sterilize the self-heating rice. After sterilization, it can be automatically removed from the machine body, making it convenient for staff to take it out.

[0007] When the self-heating rice on the material rack is sterilized, the servo motor inside the slide table operates. The servo motor, under the operation of reducer B, drives the worm gear to rotate, allowing the worm gear to mesh with the worm wheel and drive the worm wheel to rotate. The worm wheel then drives the vertical shaft to rotate, which in turn drives the platform at the top of the slide table to rotate. Subsequently, the platform drives the material rack to rotate, causing the self-heating rice on the surface of the material rack to change its orientation towards the sterilizer body as the material rack rotates, thus improving the sterilization effect.

[0008] Specifically, the bottom surface of the slide is equipped with guide wheels for support, and there are multiple sets of guide wheels.

[0009] By adopting the above technical solution, the guide wheels at the bottom of the slide table can easily assist in supporting the slide table, so that when the slide table moves inside the machine body, it can drive the material rack to move more stably and smoothly.

[0010] Specifically, the outer wall surface of the machine body is fitted with a housing located outside the sprocket, and the inner wall surface of the housing is fitted with a reducer A that is connected to the sprocket in a driving manner. The outer wall surface of the housing is fitted with an electric motor that is connected to the accelerator A in a driving manner.

[0011] By adopting the above technical solution, when sterilizing self-heating rice using sterilization equipment, the motor outside the outer shell of the machine body can be operated. The operation of the motor facilitates the rotation of the sprocket on the outside of the machine body under the operation of reducer A. The sprocket drives another set of sprockets on the outside of the machine body to rotate synchronously through the chain. The sprocket drives the lead screw in the inner slide groove of the machine body to rotate. Then the lead screw can be screwed together with the slide block, so that the slide block slides and moves in the slide groove.

[0012] Specifically, the outer peripheral opening of the machine body is equipped with an electric roller shutter door for sealing and protection, and there are two sets of electric roller shutter doors.

[0013] By adopting the above technical solution, when the slide table moves the material rack into the machine body, the electric roller shutter door can conveniently block the inlet and outlet, thereby enabling the sterilizer body inside the machine body to operate stably and sterilize the self-heating rice on the material rack.

[0014] Specifically, the outer wall surface of the machine body is equipped with a controller that is electrically connected to the electric roller shutter door, the electric motor, the servo motor, and the sterilizer body.

[0015] By adopting the above technical solution, the controller can easily control the operation of the electric roller shutter door, the electric motor, the servo motor, and the sterilizer body.

[0016] Specifically, the outer wall surface of the machine body is fitted with an inclined plate seat for moving the material cart.

[0017] By adopting the above technical solution, the inclined plate seat facilitates the sliding of the material rack off the machine body surface, making it easy to move the material rack.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The technical solution of this application, through the design of a chute, sterilizer body, slide block, slide table, material rack, and screw, allows for convenient placement of self-heating rice on the material rack when sterilizing self-heating rice using the sterilization equipment. Subsequently, the screw in the chute inside the machine rotates, allowing the screw to engage with the slide block in the chute, causing the slide block to slide and move within the chute. The slide block then facilitates the movement of the slide table, which in turn moves the material rack into the machine body. This enables the sterilizer body inside the machine to operate and sterilize the self-heating rice. After sterilization, the sterilizer body automatically moves out of the machine body for easy removal by staff.

[0020] 2. The technical solution of this application, through the design of a platform, vertical shaft, worm gear, worm, reducer B, and servo motor, enables the servo motor inside the slide to operate when the self-heating rice on the material rack is sterilized. The operation of the servo motor facilitates the rotation of the worm gear under the operation of reducer B, allowing the worm gear to mesh with the worm gear and drive the worm gear to rotate. The worm gear then drives the vertical shaft to rotate, which in turn drives the platform at the top of the slide to rotate. Subsequently, the platform drives the material rack to rotate, thereby changing the orientation of the self-heating rice on the surface of the material rack towards the sterilizer body as the material rack rotates, thus improving the sterilization effect.

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-3 This utility model provides a technical solution: a self-heating rice sterilization device, including a body 1, a sterilizer body 2 assembled inside the body 1, and a sliding table 5 slidably installed inside the body 1. A sliding groove 3 is provided on the side of the body 1 near the table 6, and there are two sets of sliding grooves 3. A sliding seat 4, which fits into the sliding groove 3, is integrally constructed on the outer wall surface of the table 6, and there are two sets of sliding seats 4. A lead screw 7, which is screwed into the sliding seat 4, is rotatably installed inside the sliding groove 3. A sprocket 8 is assembled at one end of the lead screw 7 located outside the body 1. The two sets of sprockets 8... A chain 9 for transmission is installed between the slides; a support plate 6 is rotatably mounted on the top surface of the slide 5, and a vertical shaft 13 connected to the support plate 6 is rotatably mounted inside the slide 5. A worm gear 14 is sleeved on the outer periphery of the vertical shaft 13, and a worm 15 meshing with the worm gear 14 is rotatably mounted inside the slide 5. A reducer B16 connected to the worm 15 is installed inside the slide 5, and a servo motor 17 is installed at the power input end of the reducer B16. A material rack 18 for holding self-heating rice is snapped onto the top surface of the support plate 6.

[0028] When using the sterilization equipment to sterilize self-heating rice, the self-heating rice can be conveniently placed on the material rack 18. Then, the screw 7 in the slide groove 3 inside the machine body 1 rotates, so that the screw 7 can be screwed together with the slide seat 4 in the slide groove 3, causing the slide seat 4 to slide and move in the slide groove 3. Then, the slide seat 4 can easily drive the slide table 5 to move, and the slide table 5 can move the material rack 18 into the machine body 1, so that the sterilizer body 2 inside the machine body 1 can operate and sterilize the self-heating rice. After sterilization, it can be automatically removed from the machine body 1 for easy handling by staff.

[0029] When the self-heating rice on the material rack 18 is sterilized, the servo motor 17 inside the slide table 5 is activated. The servo motor 17 drives the worm gear 15 to rotate under the operation of the reducer B16, so that the worm gear 15 can mesh with the worm wheel 14 and drive the worm wheel 14 to rotate. The worm wheel 14 can drive the vertical shaft 13 to rotate, and the vertical shaft 13 can drive the platform 6 on the top of the slide table 5 to rotate. Subsequently, the platform 6 drives the material rack 18 to rotate, so that the self-heating rice on the surface of the material rack 18 changes its orientation towards the sterilizer body 2 as the material rack 18 rotates, which helps to improve the sterilization effect.

[0030] like Figure 2 As shown, the bottom surface of the slide table 5 is equipped with guide wheels 19 for support, and there are multiple sets of guide wheels 19.

[0031] When in use, the guide wheels 19 at the bottom of the slide table 5 help to support the slide table 5, so that when the slide table 5 moves inside the machine body 1, it can drive the material rack 18 to move more stably and smoothly.

[0032] like Figure 3 As shown, the outer wall surface of the machine body 1 is equipped with a housing 10 located outside the sprocket 8, and the inner wall surface of the housing 10 is equipped with a reducer A12 that is connected to the sprocket 8 in a transmission manner. The outer wall surface of the housing 10 is equipped with a motor 11 that is connected to the accelerator A in a transmission manner.

[0033] When using the sterilization equipment to sterilize self-heating rice, the motor 11 outside the outer shell 10 of the machine body 1 can be operated. The operation of the motor 11 facilitates the rotation of the sprocket 8 on the outer side of the machine body 1 under the operation of the reducer A12. The sprocket 8 drives another set of sprockets 8 on the outer side of the machine body 1 to rotate synchronously through the chain 9. The sprocket 8 drives the lead screw 7 in the inner slide groove 3 of the machine body 1 to rotate. Then the lead screw 7 can be screwed together with the slide block 4, so that the slide block 4 slides and moves in the slide groove 3.

[0034] like Figure 1 As shown, an electric roller shutter door 20 for sealing and protection is installed inside the outer peripheral opening of the body 1, and there are two sets of electric roller shutter doors 20.

[0035] When in use, when the slide table 5 moves the material rack 18 into the machine body 1, the electric roller shutter door 20 can conveniently block the inlet and outlet, so that the sterilizer body 2 inside the machine body 1 can operate stably and sterilize the self-heating rice on the material rack 18.

[0036] like Figure 1 As shown, the outer wall surface of the machine body 1 is equipped with a controller 22 that is electrically connected to the electric roller shutter door 20, the electric motor 11, the servo motor 17 and the sterilizer body 2.

[0037] In use, the controller 22 facilitates the operation of the electric roller shutter 20, the electric motor 11, the servo motor 17, and the sterilizer body 2.

[0038] like Figure 1 As shown, the outer wall surface of the machine body 1 is equipped with a sloping plate seat 21 for moving the material cart.

[0039] When in use, the inclined plate seat 21 facilitates the sliding of the material rack 18 off the surface of the machine body 1, making it easy to move the material rack 18.

[0040] The working principle and usage process of this utility model are as follows: First, install the corresponding structural components in suitable positions. When sterilizing self-heating rice using the sterilization equipment, the rice can be conveniently placed on the material rack 18. Then, the motor 11 outside the outer casing 10 of the machine body 1 operates. The motor 11, under the operation of the reducer A12, drives the sprocket 8 on the outer side of the machine body 1 to rotate. The sprocket 8, through the chain 9, drives another set of sprockets 8 on the outer side of the machine body 1 to rotate synchronously. The sprocket 8 then drives the lead screw 7 in the inner sliding groove 3 of the machine body 1 to rotate. The lead screw 7 then screws into the slide block 4, causing the slide block 4 to slide within the sliding groove 3. The slide block 4 then moves the slide table 5, which in turn moves the material rack 18 into the machine body 1. When the slide table 5 moves the material rack 18 into the machine body 1, the electric roller shutter 20 operates to seal the inlet and outlet. Then, the sterilizer body 2 inside the machine body 1 operates and sterilizes the self-heating rice. The sterilizer automatically removes the self-heating rice from the machine body 1 after sterilization, making it convenient for staff to retrieve. The two sets of sliding tables 5 inside the machine body 1 can move synchronously, allowing them to switch positions within the machine body 1 for easier sterilization of the self-heating rice placed on the material rack 18. Simultaneously, when the self-heating rice on the material rack 18 is being sterilized, the servo motor 17 inside the sliding table 5 operates. The servo motor 17, under the operation of the reducer B16, drives the worm gear 15 to rotate, allowing the worm gear 15 to mesh with the worm wheel 14 and drive the worm wheel 14 to rotate. The worm wheel 14 then drives the vertical shaft 13 to rotate, which in turn drives the platform 6 on top of the sliding table 5 to rotate. This causes the platform 6 to rotate the material rack 18, causing the self-heating rice on the surface of the material rack 18 to change its orientation towards the sterilizer body 2, improving the sterilization effect and making the sterilization equipment more convenient for sterilizing self-heating rice.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
