Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a conveying device for packaging quick-frozen vegetables. Background Technology

[0002] In the food processing process, in order to reduce the loss of nutrients in vegetables and increase their shelf life, quick-freezing is generally used. Quick-frozen vegetables are made from fresh edible vegetables and are rapidly frozen using an ultra-low temperature rapid freezing process. They are frozen quickly in a low temperature environment below -30℃, so that the core temperature of the vegetables drops to below -18℃ in a very short time. Then they are packaged. During the packaging process, they need to be transported, and conveying equipment is used for this process. When conveying frozen vegetables, the vegetables themselves carry a large amount of frost. During the conveying process, due to vibration and collision, the frost on the surface of the product will fall off and accumulate on the surface of the conveyor belt. The ice fragments that fall during the conveying process will condense on the surface of the conveyor belt. Because the temperature of the frozen vegetables is extremely low, when the frozen vegetables fall onto the surface of the conveyor belt, the surface of the frozen vegetables will combine with the frost that has fallen onto the surface of the conveyor belt, freezing the frozen vegetables onto the surface of the conveyor belt. This causes the vegetables to stick to the conveyor belt and cannot fall normally at the normal drop point by their own weight, resulting in material blockage. Therefore, a conveying device for packaging frozen vegetables is needed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a conveying device for packaging quick-frozen vegetables, which solves the problem of existing conveying devices when conveying quick-frozen vegetables. Quick-frozen vegetables carry a large amount of frost, and during the conveying process, due to vibration and collision, the frost on the product surface falls off and accumulates on the conveyor belt surface. The falling ice crystals condense on the conveyor belt surface. Because the temperature of quick-frozen vegetables is extremely low, when quick-frozen vegetables fall onto the conveyor belt surface, their surface combines with the frost, freezing the vegetables to the conveyor belt surface. This causes the vegetables to stick to the conveyor belt and cannot fall normally from the conventional drop point under their own weight, resulting in material blockage.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a conveying device for packaging quick-frozen vegetables, comprising a conveying device and a fixing plate; The top of the conveying equipment is provided with fixing plates on both sides, and a cleaning structure is provided at the middle position of the bottom of the conveying equipment; The cleaning structure includes a mounting box, which is bolted to the middle position at the bottom of the conveying equipment. A cleaning roller is provided in the middle position inside the mounting box. A baffle is provided on one side of the cleaning roller. The two ends of the baffle are fixed to the two sides inside the mounting box. A water-absorbing roller is provided on the other side inside the mounting box. The two ends of the water-absorbing roller are rotatably connected to the two sides inside the mounting box.

[0005] Preferably, a fixing frame is provided on one side of the water absorption roller, and the two ends of the fixing frame are fixed to the two sides inside the mounting box. A spring is provided on one side of the mounting box, and a scraper is fixed on one side of the spring. One side of the scraper is attached to the outside of the water absorption roller.

[0006] Preferably, a plurality of springs are provided, and the plurality of springs are arranged at equal intervals on one side of the wiper blade.

[0007] Preferably, an air cylinder is provided on one side inside the mounting box, limit rings are fixed on the outer sides of both ends of the air cylinder, a heat-conducting sleeve is provided on the outer side of the air cylinder, a first one-way valve is installed at one end of the air cylinder, an air storage tank is provided at one end of the first one-way valve, a connecting pipe is provided at one end of the air storage tank, a nozzle frame is installed on one side of the mounting box, and one end of the connecting pipe is connected to one end of the nozzle frame.

[0008] Preferably, the top of the nozzle frame is provided with a plurality of nozzles, and the plurality of nozzles are arranged at equal intervals on the top of the nozzle frame.

[0009] Preferably, the air cylinder is equipped with a piston inside, a second one-way valve is installed inside one side of the piston, a hinge frame is hinged to one side of the piston, a connecting shaft is installed at one end of the cleaning roller, a bevel gear set is installed on the outside of the connecting shaft, a servo motor is installed at one end of the connecting shaft, a disc is installed on one side of the bevel gear set, and one end of the disc is hinged to one side of the hinge frame.

[0010] Preferably, the limiting ring is provided in two sets, and the two sets of limiting rings are symmetrically distributed at both ends of the air cylinder.

[0011] Preferably, the heat-conducting sleeve is fitted onto the outside of the air cylinder, and the heat-conducting sleeve is rotatably connected to the outside of the air cylinder.

[0012] Preferably, the heat-conducting sleeve is made of metallic copper.

[0013] Preferably, the two ends of the spring are respectively connected to one side of the wiper blade and one side of the fixing frame, and the wiper blade and the spring form a telescopic structure.

[0014] The present invention provides a conveying device for packaging quick-frozen vegetables, the advantages of which are: By incorporating a cleaning structure, the extra heat generated by the reciprocating motion of the piston inside the air cylinder actively heats and melts frost. Combined with multi-stage cleaning and drying, this ensures that the conveyor belt surface remains clean and dry, fundamentally eliminating the phenomenon of "frozen vegetables sticking together after contact with the air cylinder." This ensures that the vegetables can fall smoothly at the drop point by gravity, solving the problem of material blockage and thus guaranteeing the continuous operating efficiency of the packaging line. Furthermore, by utilizing the principle of frost melting and absorbing heat, the air cylinder heated by compressed air is cooled in reverse. This self-circulating cooling system requires no additional energy consumption and can keep the air cylinder working within a safe temperature range, significantly improving the reliability of the equipment and the service life of core components, and realizing the utilization of bidirectional energy. Furthermore, through a triple-stage dewatering design, residual moisture from the de-icing process on the conveyor belt is thoroughly removed, effectively preventing secondary icing for a long time. 1. The rotating cleaning roller, in conjunction with the brush bristles, scrapes away water stains and solid impurities after the conveyor belt has melted ice. The debris and wastewater are then thrown into the installation box for collection. 2. The absorbent cotton on the surface of the absorbent roller absorbs the remaining water stains on the conveyor belt. Combined with the spring-loaded scraper, the absorbent cotton is automatically squeezed to drain the water, so that the absorbent roller can continuously and autonomously dehydrate without the need for manual disassembly and cleaning of the cotton. 3. The air tank stores high-pressure air, which is sprayed out through the nozzle frame to sweep the conveyor belt and remove the trace amount of residual water on the surface; the three-stage water removal works together to thoroughly remove the moisture on the surface of the conveyor belt, preventing the moisture from condensing back into ice at the source, thus making the cleaning effect better.

The heat-conducting sleeve 308 is sleeved on the outside of the air cylinder 3016, and the heat-conducting sleeve 308 is rotatably connected to the outside of the air cylinder 3016; the heat-conducting sleeve 308 is made of copper; the two ends of the spring 3021 are respectively connected to one side of the wiper blade 3020 and one side of the fixing frame 3019, and the wiper blade 3020 and the spring 3021 form a telescopic structure.

[0020] Before conveying the frozen vegetables, the mounting box 302 is bolted to the middle of the bottom of the conveyor 1. After the mounting box 302 is installed, the frozen vegetables are poured onto the surface of the conveyor 1, and then the conveyor 1 is started to convey the frozen vegetables. When the frozen vegetables are conveyed on the surface of the conveyor 1, they will carry a large amount of frost. During the conveying process, due to vibration and collision, the frost on the surface of the frozen vegetables will fall off and accumulate on the surface of the conveyor belt. During the conveying process, the frost will condense on the surface of the conveyor belt. If this part of the frost is not cleaned, when the frozen vegetables come into contact with the surface of the conveyor belt again, due to the extremely low temperature of the frozen vegetables, the interface between the two will refreeze instantly, causing the vegetables to stick to the conveyor belt and not be able to fall normally at the normal drop point by their own weight, causing a blockage. Therefore, when When conveying, the external power supply starts the servo motor 301. After starting, the servo motor 301 drives the cleaning roller 306 to rotate to one side through the connecting shaft 3011. During the rotation of the connecting shaft 3011, the bevel gear set 3012 will rotate. During the rotation of the bevel gear set 3012, the disc 3010 will rotate. During the rotation of the disc 3010, the piston 3017 will reciprocate inside the air cylinder 3016 through the hinge frame 309. When the piston 3017 moves to one end, the second one-way valve 3018 inside the piston 3017 closes and the first one-way valve 3014 opens, thereby delivering the air inside the air cylinder 3016 to the air storage tank 3013. When the piston 3017 is pulled back, the second one-way valve 3018 opens and the first one-way valve 3014 closes, thereby completing the effect of continuous aeration. When piston 3017 reciprocates inside cylinder 3016, it violently compresses the air inside cylinder 3016, causing a rapid increase in its internal energy and a rapid rise in temperature. This heat is then conducted through cylinder 3016 to the interior of heat-conducting sleeve 308, heating it. The heated heat-conducting sleeve 308 then contacts the bottom surface of the conveyor belt, melting the frost on its surface. The melted frost falls into the mounting box 302, completing the cleaning of the frost on the conveyor belt surface and preventing the frozen vegetables from thawing when they fall onto the conveyor belt. Combined with the frost that falls onto the surface of the conveyor belt, the quick-frozen vegetables are frozen to the surface of the conveyor belt, causing the vegetables to stick to the conveyor belt and unable to fall normally at the normal drop point by their own weight, resulting in material blockage. Furthermore, when the heat-conducting sleeve 308 melts the frost, the large amount of heat absorbed by the melting frost can directly cool the air cylinder 3016 in reverse, extending the service life of the piston 3017. It is equivalent to a self-circulating cooling system, which can keep the air cylinder 3016 working in a safe temperature range, significantly improving its reliability and lifespan, and achieving the effect of cooling the air cylinder 3016 in reverse when cleaning frost. When the connecting shaft 3011 rotates, it drives the cleaning roller 306 to rotate. As the cleaning roller 306 rotates to one side, its surface bristles come into contact with the bottom surface of the conveyor belt inside the conveyor equipment 1. At this time, the rotating cleaning roller 306 cleans the water stains and impurities on the bottom surface of the conveyor belt. The impurities and water stains cleaned by the rotating cleaning roller 306 are thrown to one side of the baffle 307 and then fall into the mounting box 302, completing the initial cleaning of the water stains. After the initial cleaning of the water stains on the conveyor belt surface, the water suction roller 305 rotates during its movement through contact with its surface. As the water suction roller 305 rotates, its absorbent cotton further cleans the remaining water stains on the conveyor belt surface. When the water suction roller 305 rotates, the scraper 3020, squeezed by the spring 3021, adheres to the surface of the water suction roller 305, thus scraping the water... The water-absorbing cotton on one side of the plate 3020 is slightly squeezed. As the water-absorbing cotton is rotated while absorbing water, the scraper 3020 can squeeze the water-absorbing cotton, squeezing the absorbed water into the installation box 302, thus achieving an automatic water-squeezing effect. After the water-absorbing cotton absorbs the water, there will be virtually no residual water stains on the surface of the conveyor belt. At this time, the gas delivered to the air tank 3013 will be delivered to the nozzle frame 303 through the connecting pipe 304, and then blown out through the top nozzle, so that the air blows to the surface of the bottom of the conveyor belt, carrying away the surface moisture, ensuring the surface of the conveyor belt is dry, and preventing frozen vegetables from freezing on the surface due to frost residue, which would make it difficult to drop the frozen vegetables and cause blockage, affecting the conveying efficiency. This completes the automatic cleaning of frost on the surface of the conveying equipment 1.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
