[0023] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-6 , the present invention provides a technical solution: UVC disinfection equipment applied to cold chain food, including cold chain food sterilization equipment, the cold chain food sterilization equipment includes a sterilization chamber 1, a control panel 2, an ultraviolet irradiator 3, a lifting chamber 4, a placement chamber 5 and a door 6;

[0025] The lifting chamber 4 includes a motor 41, an output shaft 411, a telescopic joint 412 and a threaded rod 413. The control panel 2 is fixedly installed on the right side of the sterilization chamber 1, and an intelligent control system is arranged inside. The ultraviolet irradiator 3 is fixedly installed above the inner wall of the sterilization chamber 1. The door 6 is axially connected to one side of the sterilization chamber 1. The lifting chamber 4 is fixedly installed at the bottom of the inner wall of the sterilization chamber 1.

[0026] The motor 41 is fixedly mounted on the bottom of the inner wall of the lifting chamber 4, the output shaft 411 is fixedly connected to the output end of the motor 41, the telescopic joint 412 is fixedly mounted on the upper end of the output shaft 411, the threaded rod 413 is fixedly mounted on the upper end of the telescopic joint 412, and the upper end of the threaded rod 413 is connected to the bottom bearing of the placement chamber 5, the placement chamber 5 is located below the ultraviolet irradiator 3, a threaded hole is provided above the lifting chamber 4, and the threaded rod 413 is threadedly connected in the threaded hole;

[0027] The operator opens the door 6 and puts several pieces of meat into the placement chamber 5, then starts the cold chain food sterilization equipment. The ultraviolet irradiator 3 emits ultraviolet rays to sterilize the meat. During the sterilization process, the motor 41 runs and drives the telescopic joint 412 to rotate through the output shaft 411. The telescopic joint 412 drives the threaded rod 413 to move upward while rotating through the threaded hole, thereby driving the placement chamber 5 to move upward, and the telescopic joint 412 is elongated, so that the distance between the ultraviolet irradiator 3 and the meat is shortened, thereby enhancing the sterilization intensity and improving the sterilization efficiency. Then the motor 41 rotates in the opposite direction, so that the placement chamber 5 moves downward and resets, thereby widening the distance between the ultraviolet irradiator 3 and the meat again, avoiding excessive irradiation that leads to a decrease in the nutritional value of the meat and improving the sterilization quality.

[0028] A weight recognition module is provided inside the placement cavity 5, and a frequency adjustment module is provided on the inner wall of the motor 41. The weight recognition module is electrically connected to the frequency adjustment module. The weight recognition module is used to recognize the weight of the meat block stored in the placement cavity 5, and the frequency adjustment module is used to control the number of times the motor 41 rotates back and forth alternately according to the weight of the meat block.

[0029] The number of adjustment modules is as follows: Q is the number of times the motor 41 rotates alternately in the forward and reverse directions. max is the maximum number of times the motor 41 rotates alternately in the forward and reverse directions, G is the weight of the meat in the placement cavity 5, and G max The maximum weight that the placement cavity 5 can bear is as follows: the heavier the meat is, the more meat pieces there are inside. At this time, the motor 41 rotates more frequently in the forward and reverse directions, so that the placement cavity 5 moves upward, and the distance between the ultraviolet irradiator 3 and the meat is shortened more frequently, thereby greatly improving the sterilization effect. Conversely, in the case of fewer pieces of meat, the number of high-intensity irradiations is reduced, thereby ensuring the quality of the meat, and achieving intelligent sterilization, which greatly improves the sterilization effect.

[0030] A stirring plate 51 is provided inside the placement chamber 5, a support plate 52 is fixed to the bottom of the stirring plate 51, a connecting rod 53 is fixed to the bottom of the support plate 52, a slide groove is provided at the bottom of the placement chamber 5 and above the lifting chamber 4, the connecting rod 53 is inserted into the slide groove of the placement chamber 5, and a telescopic rod 54 is fixed to the lower end, a ball rod 55 is fixed to the lower end of the telescopic rod 54, the ball rod 55 is inserted into the slide groove of the lifting chamber 4, and a limit block 56 is fixed to the outer side of the upper end, and the limit block 56 is in contact with the bottom surface of the slide groove, slide rails are fixed on both sides of the bottom of the slide groove, and the limit block 56 is slidably connected in the slide rails, so that the limit block 56 and the lifting chamber 4 can only slide or rotate relative to each other in the horizontal direction, and remain stationary with each other in the vertical direction.

[0031] A ball 551 is fixed at the bottom end of the ball rod 55, a ball 552 is fixed inside the ball 551, a toothed disc 42 is installed on the bearing at the bottom of the inner wall of the lifting chamber 4, a gear 43 is fixed on the outside of the output shaft 411, and meshes with the toothed disc 42, a squeezing ball 421 is connected to the spring above the toothed disc 42, and after the toothed disc 42 rotates, the squeezing ball 421 contacts the ball 551;

[0032] Through the above steps, when the output shaft 411 rotates, the gear 43 is driven to rotate, thereby driving the toothed disc 42 to rotate through meshing, and the toothed disc 42 drives the squeezing ball 421 to rotate around the center until it is squeezed and rubbed against the ball 551, and the spring under the squeezing ball 421 is deformed by force. At the same time, the ball 551 is forced to drive the ball rod 55 to move forward, and the ball rod 55 drives the connecting rod 53 to move forward through the telescopic rod 54, and the connecting rod 53 drives the stirring plate 51 and the support plate 52 to move forward, which can stir the meat pieces, so that the meat pieces are evenly exposed to ultraviolet rays, thereby further improving the fire extinguishing effect and sterilization efficiency. During the lifting and lowering process of the placement chamber 5, the meat pieces are constantly stirred, and the more meat pieces there are, the more times they are stirred, thereby fully ensuring that the meat pieces can be sterilized by ultraviolet rays, and avoiding the phenomenon that the meat pieces at the bottom cannot be exposed to the ultraviolet rays.

[0033] A pneumatic chamber 44 is fixed to the front side of the inner wall of the lifting chamber 4, and a pneumatic plate 441 is slidably connected to the inner wall of the pneumatic chamber 44. A pneumatic rod 442 is fixed to one side of the pneumatic plate 441. After the ball rod 55 moves, it contacts the pneumatic rod 442. A push-pull plate 57 is fixed to the inner side of the ball rod 55.

[0034] The air pressure plate 441 is connected to the spring on the front side of the inner wall of the air pressure chamber 44, the front side pipeline of the air pressure chamber 44 is connected to the air chamber 45, a slide cylinder 46 is fixed to the front side of the inner wall of the lifting chamber 4, the inner sliding connection of the slide cylinder 46 is connected to a slide rod 461, after the slide rod 461 is extended, it contacts with the push-pull plate 57, the front end of the slide rod 461 is connected to the spring on the front side of the inner wall of the slide cylinder 46, the front side of the slide cylinder 46 is connected to the pipeline of the air chamber 45, and a pressure valve is arranged in the pipeline.

[0035] The front side of the air pressure chamber 44 is connected to an external pipeline, and a one-way valve is arranged in the pipeline, and the front side of the slide cylinder 46 is connected to an external control valve pipeline;

[0036] When the ball rod 55 moves forward, it contacts the gas pressure rod 442 and pushes the gas pressure rod 442 forward. The gas pressure rod 442 drives the gas pressure plate 441 to slide forward along the inner wall of the gas pressure chamber 44. The spring is deformed by force. After that, when the extrusion ball 421 is out of contact with the ball body 551, the rear side of the ball rod 55 is no longer stressed. The spring generates a reaction force to push the ball rod 55 back to its original position through the gas pressure rod 442. Therefore, when the meat is stirred, the gas pressure chamber 44 continuously draws gas from the outside and injects it into the gas chamber 45. When there are more pieces of meat, the stirring times are more, and the ball rod 55 moves forward and backward. The more times it moves, the more the air pressure of the gas entering the air cavity 45 reaches the pressure limit of the pressure valve, causing the pressure valve to open, and the gas quickly enters the slide 46 through the pipe, pushing the slide rod 461 to move backward. The spring is deformed by the force, pushing the push-pull plate 57, thereby causing the ball rod 55 to rotate through the push-pull plate 57, causing the support plate 52 and the stirring plate 51 to rotate. It is not easy to turn over most of the meat chunks, so the turning strength of the meat chunks is strengthened, and the strength of stirring the meat chunks is increased, thereby further ensuring that more meat chunks can be sterilized, and further improving the sterilization quality.

[0037] The push-pull plate 57 and the rear end of the slide bar 461 are both magnetic, and the magnetic poles are opposite;

[0038] The slide bar 461 pushes the push-pull plate 57. When the support plate 52 and the stirring plate 51 need to rotate continuously to turn the meat pieces, this is achieved by periodically opening and closing the external control valve. The specific operation is: when the slide bar 461 extends out and pushes the push-pull plate 57 to rotate to a certain angle, the push-pull plate 57 and the slide bar 461 are always adsorbed together under the action of magnetism. At this time, the external control valve is opened, and the air pressure in the slide cylinder 46 returns to normal. Under the drive of the spring reaction force, the slide bar 461 and the push-pull plate 57 are reset, and then the external control valve is closed. The slide bar 461 continues to move to the rear side after the pressure valve is opened. The slide bar 461 extends out again and pushes the push-pull plate 57 to rotate, so that the support plate 52 and the stirring plate 51 continuously stir the meat pieces, the sterilization efficiency is greatly improved, and the meat pieces can be fully sterilized by ultraviolet rays.

[0039] After the second ball 552 rotates, the extrusion ball 421 contacts the first ball 551 and the second ball 552;

[0040] And when the ball rod 55 rotates, the second ball 552 rotates around the center, so that the second ball 552 can also contact the squeezing ball 421. The squeezing ball 421 first squeezes the second ball 552 and then squeezes the first ball 551, thereby further accelerating the frequency of turning the meat pieces, so that no matter how much or how little meat pieces there are, they can be fully sterilized, and the sterilization effect is greatly enhanced.
