[0017] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. This embodiment is written in a progressive manner.

[0018] As Figures 1 to 4 shown, an automatic material conveying device for a fluid sterilization pot of the present invention includes a sterilization pot and a conveying structure. The sterilization pot includes a pot body 1 located on the lower side and a pot cover 2 covering the top opening of the pot body 1. The conveying structure is located on the pot cover 2. The conveying structure includes two conveying channels 3 distributed left and right and two conveying rings 4 distributed front and back. The conveying channels 3 are installed on the pot cover 2 and extend into the pot body 1. The two conveying channels 3 are on the same circle. Each conveying ring 4 passes through the two conveying channels 3, and the outer wall of the conveying ring 4 is slidably installed on the inner wall of the conveying channel 3. The conveying ring 4 is coaxial with the conveying channel 3. The upper region between the two conveying channels 3 is outside the sterilization pot and is used for loading and unloading. The lower region between the two conveying channels 3 is inside the sterilization pot and is used for sterilization treatment. A plurality of piston plates 5 are provided on the two conveying rings 4. When the piston plate 5 rotates with the conveying ring 4 into the conveying channel 3, the piston plate 5 can block the inside of the conveying channel 3. A carrying mechanism is provided between adjacent two piston plates 5. The carrying mechanism is used to carry products. A power mechanism is provided on the pot cover 2. The power mechanism is used to drive the conveying ring 4 to rotate.

[0019] Specifically, the power mechanism can drive the two conveying rings 4 to rotate. The two conveying rings 4 rotate on the conveying channel 3, and the conveying channel 3 supports the conveying rings 4. At the same time, the conveying rings 4 can drive a plurality of piston plates 5 to rotate continuously. When the piston plate 5 moves into the conveying channel 3, the piston plate 5 seals the conveying channel 3. Therefore, to prevent the inside of the sterilizer from communicating with the outside air through the conveying channel 3, when the conveying ring 4 rotates, there is always a piston plate 5 in the conveying channel 3 to seal the conveying channel 3. This not only satisfies the continuous rotational movement of the plurality of piston plates 5 but also ensures that there is a specified pressure inside the sterilizer. During actual use, when the bearing mechanism between two adjacent piston plates 5 moves between the two conveying channels 3 outside the sterilizer, the product is placed on the bearing mechanism. Then, the conveying ring 4 and the piston plate 5 will carry the product into the two conveying channels 3 inside the sterilizer, and the sterilizer performs high-temperature and high-pressure sterilization on the product. When the product treatment is completed, the conveying ring 4 and the piston plate 5 carry the product out of the sterilizer again. Since a plurality of bearing mechanisms can continuously convey the product, the continuous conveying and sterilization effect of the sterilizer on the product can be achieved.

[0020] Since the inside of the sterilizer is in a continuously high-pressure state, even when two adjacent piston plates 5 move outside the sterilizer and carry some high-pressure air, the amount carried is small, and the inside of the sterilizer can still quickly replenish high-pressure air and keep the sterilizer in a high-pressure state all the time. At the same time, to improve the sealing performance between the piston plate 5 and the conveying channel 3, structures such as sealing rings and sealing strips can be installed on the piston plate 5. And even if gas leaks through the gap between the piston plate 5 and the conveying channel 3 due to too high pressure in the sterilizer, it will not affect the normal use of the sterilizer because during actual use, when the pressure in the sterilizer reaches a certain value, it needs to exhaust gas through the pressure relief valve. Therefore, the setting of the conveying channel 3 and the piston plate 5 can ensure that the pressure in the sterilizer is within the specified range.

[0021] By using two conveying channels 3 as the channels for the continuous rotational movement of a plurality of piston plates 5, it can ensure that the inside of the sterilizer is isolated from the outside, thus preventing the leakage of the pressure inside the sterilizer. At the same time, the continuous conveying work of the bearing mechanism between two adjacent piston plates 5 is realized, and thus the continuous conveying work of the product is realized. In this way, it can ensure that the sterilizer continuously sterilizes the product in a sealed state. This conveying method can greatly improve the continuity of product treatment, improve work efficiency, and at the same time avoid the cumbersome operations of frequently opening and closing the sterilizer and repeating the loading and unloading in the traditional method, as well as the energy loss and time waste caused by pressure leakage every time the sterilizer is opened and the need to repeatedly pressurize the sterilizer.

[0022] Preferably, the carrying mechanism includes two auxiliary plates 6 installed between two adjacent piston plates 5. A support shaft 7 is rotatably provided on each auxiliary plate 6. A carrying basket 8 is arranged between the two support shafts 7, and the center of gravity of the carrying basket 8 is below the axis of the support shaft 7; Wherein, a damping structure is provided on each support shaft 7.

[0023] Specifically, the two auxiliary plates 6 can assist in connecting two adjacent piston plates 5, thereby improving the strength of multiple piston plates 5. And the two auxiliary plates 6 can support the support shaft 7 and the carrying basket 8. Since the center of gravity of the carrying basket 8 is below the axis of the support shaft 7, when the product is placed into the carrying basket 8 through the top opening of the carrying basket 8, as the conveying ring 4 rotates, the opening of the carrying basket 8 always faces upward, so that the product can always be kept in the carrying basket 8. And when the carrying basket 8 and the product are moved into the sterilization pot, the high-temperature gas or water flow sprayed downward in the sterilization pot can directly sterilize and disinfect the product. The support shaft 7 supports the carrying basket 8. As the conveying ring 4 rotates, due to the action of the center of gravity of the carrying basket 8, the support shaft 7 rotates relative to the auxiliary plate 6.

[0024] Preferably, the damping structure includes a circular bin 9 fixed on the auxiliary plate 6. A fluid is contained inside the circular bin 9. The support shaft 7 passes through the circular bin 9 and rotates relatively. A push plate 10 is provided on the support shaft 7 inside the circular bin 9, and the push plate 10 slides through the support shaft 7 along the radial direction of the support shaft 7. A wedge 11 is provided at the bottom of the inner wall of the circular bin 9, and there is a gap for the fluid to flow between the top of the wedge 11 and the outer wall of the support shaft 7.

[0025] Specifically, the fluid contained in the circular bin 9 is an oil-based fluid with a certain viscosity. When the support shaft 7 rotates, the support shaft 7 can drive the push plate 10 to rotate. The push plate 10 can push the fluid in the circular bin 9 to flow. Since when the fluid flows through the gap between the wedge 11 and the support shaft 7, the gap is small, the fluid is subject to a large resistance. And because the fluid has a certain viscosity, the push plate 10 cannot rotate quickly in the circular bin 9, and the push plate 10 can only rotate slowly. In this way, the damping effect on the support shaft 7 and the carrying basket 8 can be achieved, avoiding the product in it from falling off due to the random rotation of the carrying basket 8. When the push plate 10 rotates to the position of the wedge 11, the inclined surface of the wedge 11 will push the push plate 10 to slide through the support shaft 7, and the top of the push plate 10 extends out of the top of the support shaft 7, so as to continue to push the fluid to flow through the push plate 10. At the same time, because the fluid has a viscosity, in the natural state, the push plate 10 will not slide randomly on the support shaft 7.

[0026] Preferably, the two conveying channels 3 are communicated through a connecting pipe 12, and the connecting pipe 12 is located in the middle of the conveying channel 3. When the conveying ring 4 rotates, at least two piston plates 5 are simultaneously present in the conveying channel 3; Among them, the piston plate 5 is moved into the sterilization pot through a conveying channel 3. This conveying channel 3 serves as the input end, and the other conveying channel 3 serves as the output end. A guiding pipe 13 is communicated and provided on the upper side of the conveying channel 3 at the output end.

[0027] Specifically, when two adjacent piston plates 5 enter the conveying channel 3 at the input end, the air at normal temperature and pressure will be carried between the two adjacent piston plates 5, and the air at high temperature and pressure will be carried between the two adjacent piston plates 5 in the conveying channel 3 at the output end. At this time, the high-temperature and high-pressure gas in the conveying channel 3 will flow into the other conveying channel 3 through the through pipe 12, so as to heat and pressurize the air at normal temperature and pressure, which is convenient for recycling energy, and at the same time convenient for pre-pressurizing and pre-heating the products in the conveying channel 3 at the inlet end. When two adjacent piston plates 5 in the conveying channel 3 at the output end move to the upper side inside the conveying channel 3, the guiding pipe 13 is communicated with the space between the two adjacent piston plates 5. At this time, the high-temperature and high-pressure air between the two adjacent piston plates 5 will be discharged to the external heat energy recovery device through the guiding pipe 13, which is convenient for recycling energy, and at the same time avoids the random discharge of high-temperature and high-pressure air and scalding the workers.

[0028] More preferably, the power mechanism includes a motor 14 and a rotating column 15. The output end of the motor 14 is in transmission connection with the rotating column 15. The axis of the rotating column 15 is horizontal, and the rotating column 15 is in transmission contact with the two conveying rings 4; Among them, the rotating column 15 is made of anti-slip rubber.

[0029] Specifically, the motor 14 can drive the two conveying rings 4 to rotate through the rotating column 15, so as to drive the equipment to operate. At the same time, by making the rotating column 15 of anti-slip rubber, the surface of the conveying ring 4 can be kept smooth while ensuring the normal transmission between the rotating column 15 and the conveying ring 4, which is convenient for the conveying ring 4 to contact the conveying channel 3, and avoids the leakage of the pressure in the sterilization pot through the teeth when the rotating column 15 and the conveying ring 4 are in gear transmission.

[0030] More preferably, a core shaft 16 is provided in the middle of the rotating column 15. Support rods 17 are provided at both ends of the core shaft 16. The core shaft 16 rotates on the support rods 17. The support rods 17 are vertical. A support sleeve 18 is slidably sleeved on the support rods 17. The bottom of the support sleeve 18 is fixed on the pot cover 2. The support rods 17 and the support sleeve 18 are connected by a leaf spring 19.

[0031] Specifically, the support rods 17 and the support sleeve 18 can support the rotating column 15 through the core shaft 16. The leaf spring 19 will provide an upward elastic thrust to the rotating column 15 through the support rods 17 and the core shaft 16, so as to make the rotating column 15 in close contact with the conveying ring 4 and improve the transmission effect.

[0032] Preferably, the motor 14 is fixed on the pot lid 2. A worm 20 is provided at the upper output end of the motor 14. A worm gear 21 is meshed with the worm 20, and the worm gear 21 is drivingly connected to the core shaft 16.

[0033] Specifically, the motor 14 can drive the rotating column 15 through the worm 20, the worm gear 21 and the core shaft 16. Since the leaf spring 19 needs to provide an elastic driving force for the rotating column 15, it is necessary to rely on the worm 20 and the worm gear 21 to achieve the normal transmission between the motor 14 and the rotating column 15, that is, the movement of the rotating column 15 in the vertical direction will not affect the transmission relationship between the worm gear 21 and the worm 20.

[0034] Preferably, a protective cover 22 is further included. The protective cover 22 is located outside the motor 14, the worm 20 and the worm gear 21, and the protective cover 22 is fixed on the pot lid 2.

[0035] Specifically, the protective cover 22 can block the water droplets on the conveying ring 4 and protect the motor 14, the worm 20 and the worm gear 21.

[0036] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
