Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cold storage, in particular to a flat shelf for cold storage. BACKGROUND

[0002] In the field of cold chain logistics and food processing, as the core storage facility, the running stability, storage efficiency and maintenance cost of the shelf inside the cold storage are directly related to the quality of goods and the operating efficiency of enterprises. With the growth of the demand for batch turnover of fresh and frozen products, the traditional flat shelf for cold storage gradually exposes many adaptability defects, which cannot meet the efficient and safe needs of modern cold chain storage. First, the low-temperature and high-humidity environment in the cold storage easily causes water vapor to condense into frost at the bottom of the tray. The existing shelf generally lacks a targeted automatic cleaning mechanism. If the frost layer attached to the bottom of the tray is not cleaned in time, it will contaminate other storage areas with the tray turnover, and the thickening of the frost layer will cause uneven contact between the tray and the supporting surface, which is prone to cause goods to fall and damage in the cold storage vibration environment, especially for perishable goods such as fresh and frozen products. The existing cleaning method relies on manual regular wiping, which not only needs to frequently enter and exit the low-temperature environment for operation, but also has limited cleaning effect on hidden parts such as the inner wall of the cleaning hole, and also increases the labor and time cost of enterprises. Secondly, the tray conveying mechanism of the traditional shelf mostly adopts a simple push-pull structure, which has obvious positioning defects, lacks stable synchronous transmission design, and the push plate movement trajectory is easy to deviate, which causes the tray to fail to accurately dock the storage position, not only causing waste of storage space, but also possibly causing tray collision and damaging equipment. For the scene of continuous feeding of multiple trays, the existing mechanism cannot realize the orderly transmission of "consistent displacement and position relay". Furthermore, the existing cleaning technology has low efficiency and secondary pollution, which further aggravates equipment wear and tear. Ordinary brush cleaning can only remove the surface frost layer, and the effect is limited for stubborn frost blocks that are entangled between the brushes or closely attached. Long-term accumulation will cause the cleaning parts to fail. Although some shelves are equipped with a defrosting device, high-temperature defrosting easily causes the goods to thaw and deteriorate, and the "water-slag mixture" after melting relies on natural flow to discharge, which is easy to be retained and frozen in the low-temperature environment, blocking the drainage channel and affecting the movement flexibility of the mechanism. Therefore, we propose a flat shelf for cold storage. SUMMARY

When the tray is transmitted to the leftmost side, the left edge of the bottom of the tray first contacts with the top of the supporting plate 206. With the continuous movement of the tray to the left, the weight of the tray acts on the top of the two supporting plates 206, overcoming the supporting force of the second spring 15 of the supporting plate 206, so that the supporting plate 206 rotates around the bearing. When the supporting plate 206 rotates, the first sliding groove 304 on the surface of the supporting plate 206 deflects synchronously with the supporting plate 206. The first connecting rod 305 in the first sliding groove 304 slides in the sliding groove. The two first connecting rods 305 are fixedly connected through the second connecting rod 306, forming a synchronous motion structure. The second connecting rod 306 pushes one end of the connecting rod 205 to move downward, so that the connecting rod 205 rotates counterclockwise around the supporting rod 204. The other end of the connecting rod 205 is lifted upward with the rotation, and the third connecting rod 311 at the end thereof is in sliding fit with the third sliding groove 310 of the lifting frame 309. The upward component force pushes the lifting frame 309 to vertically slide upward along the first limiting groove 308 in the inner surface of the support frame 201. The top of the lifting frame 309 is fixed with the connecting frame 301, and the connecting frame 301 moves upward synchronously with the lifting frame 309. The inner surface of the connecting frame 301 is in sliding fit with the outer surface of the limiting frame 9. The second rack 302 on the outer surface of the connecting frame 301 is in mesh with the second gear 303 on the outer surface of the rotating rod 6. When the second rack 302 moves upward, it drives the second gear 303 to rotate, and further drives the rotating rod 6 to rotate around the bearing in the inner surface of the rack 1. The first rotating plate 7 on the outer surface of the rotating rod 6 swings synchronously with the rotating rod 6. Through the second rotating plate 8, two positioning rods 208 are pulled to slide horizontally to the middle along the positioning groove 207 in the outer surface of the rack 1. When the positioning rod 208 slides to the middle,The first gear 211 near the end is engaged with the first rack 212 on the inner surface of the frame 1, and the engagement drives the positioning rod 208 to rotate, and the roller 209 on the outer surface of the positioning rod 208 rotates synchronously with the positioning rod 208, and the brush 210 on the outer surface of the roller 209 is in sliding contact with the inner wall of the cleaning hole 203 on one hand to clean the frost layer accumulated in the cleaning hole 203 by friction, and on the other hand, the top of the brush 210 is in contact with the bottom of the tray to rotate and wipe the frost layer attached to the bottom of the tray, so as to avoid the tray from bringing the frost layer to pollute other storage areas. When the support plate 206 is rotated under pressure, the heating plate embedded in the support plate 206 is started, and the heat released by the heating plate is transmitted to the upper surface of the support plate 206 through heat conduction, and then to the bottom of the tray, so as to heat the frost layer on the bottom of the tray at a low temperature to avoid thawing of the goods. The tray is a heat-insulating tray to avoid heating the goods on the top to melt the frost layer, and the melted frost water is mixed with the residues cleaned by the brush 210 to form a “water-residue mixture”, which then falls into the support frame 201, and the exhaust air pipe 12 connected to the lower surface of the support frame 201 is externally connected to a negative pressure exhaust device to extract the “water-residue mixture” in the residue collecting cavity outside the frame 1 through the negative pressure effect and transport it to a collection box outside the cold storage. When the support rod 204 rotates with the connecting rod 205, the fixed frame 501 fixed on the outer surface of the support rod 204 synchronously deflects, the stop rod 502 on the outer surface of the fixed frame 501 is in contact with the resisting rod 504 of the rotating ring 503, and as the support rod 204 continues to rotate, the stop rod 502 pushes the resisting rod 504 to rotate around the support rod 204, the rotating ring 503 synchronously rotates and pulls the first pull rod 505, and the slider 506 at the other end of the first pull rod 505 slides along the sliding groove 509 of the second pull rod 508, while compressing the first spring 510, to complete the knocking power storage. When the resisting rod 504 rotates with the rotating ring 503 to the other side position, the first spring 510 generates an instantaneous pushing force to push the slider 506 to slide reversely, drives the second pull rod 508 to swing rapidly around the support stand 507, and the knocking wheel 511 of the second pull rod 508 rapidly hits the knocking plate 512 on the inner surface of the support frame 201 with the swinging action to generate vibration, which is transmitted to the positioning rod 208, the roller 209 and the brush 210 through the knocking plate 512 to shake off the stubborn frost blocks and residues entangled between the bristles of the brush 210, and at the same time, the vibration is transmitted to the support plate 206 to accelerate the melting of the frost layer remaining on the surface of the support plate 206 and strengthen the cleaning effect. After the operator extracts the tray from the left material taking area, the pressure of the tray on the support plate 206 disappears, the second spring 15 on the upper surface of the support stand 507 elastically resets to push the mounting frame 16 upwards, the pulley 17 on the inner surface of the mounting frame 16 slides along the limiting plate 14 on the lower surface of the positioning ring 13 to generate an upward pushing force to drive the limiting plate 14 to rotate around the support rod 204, the positioning ring 13 synchronously rotates with the limiting plate 14 to drive the support rod 204 to rotate reversely, and then through the linkage of the connecting rod 205, the second connecting rod 306 and the first connecting rod 305, the support plate 206 is pulled to rotate reversely to restore the initial raised state, at the same time, the rotation of the support rod 204 drives the fixed frame 501 to reset,The knocking mechanism 5 returns to the initial state, completes a "material taking, cleaning, resetting" cycle, and the whole machine returns to the standby state to perform the next round of operation.
