Description

Technical Field

[0001] The invention relates to the technical field of conveyors, and in particular to a belt conveyor used for fresh-keeping food production. Background Art

[0002] Quick freezing to lock in freshness is a technology that uses ultra-low temperature to quickly freeze food ingredients to achieve a fresh-keeping effect. Quick freezing to lock in freshness technology uses ultra-low temperature environments, such as -196°C in liquid nitrogen quick freezing technology, to quickly cool food ingredients in a very short period of time, and through the ice crystal growth zone, reduce the loss of food nutrients. This technology can form evenly distributed fine crystals in food tissues, maximize the maintenance of food tissue structure, and maintain food quality. Compared with traditional quick freezing technology, quick freezing to lock in freshness technology does not destroy the cell structure, protein and fiber structure of food, can instantly lock in moisture, achieve sterilization function, and preserve the fresh state and nutrients of food ingredients to the greatest extent.

[0003] The refrigerated fresh-keeping food bags are transported to transportation equipment or reprocessing equipment through belt conveyors. Since the temperature during the refrigeration process is generally around zero degrees, when there is water on the surface of the fresh-keeping bags, the water will freeze and adhere to the surface of the fresh-keeping bags under low temperature conditions. When there are bumps during transportation or squeezing and collisions between adjacent fresh-keeping bags, the sharp edges of the ice layer will scratch the fresh-keeping bags, causing the food inside the fresh-keeping bags to come into contact with the outside air, making it impossible for the food to be effectively fresh-keeping treated.

[0004] Although the existing belt conveyor used for fresh-keeping food production can beat the ice layer on the fresh-keeping bag by cooperating with a spring and a clapper to remove the ice layer on the fresh-keeping bag, the consistency of the beating force cannot be guaranteed for fresh-keeping bags of different specifications. The uncontrollable beating force may cause damage to the fresh-keeping bag and affect the fresh-keeping effect of the fresh-keeping bag.

The conveyor belt 1 203 and the conveyor belt 2 204 drive the fresh-keeping bag, the rack plate 318 and the moving plate 501 to move from left to right through the placement plate 205.

[0063] When the rack plate 318 contacts the transmission gear 1 308, the transmission gear 1 308 drives the rotating rod 1 309 to rotate by meshing with the transmission gear 1 308, and the rotating rod 1 309 drives the transmission gear 2 310 to rotate. The transmission gear 2 310 drives the sliding column 316 to rotate by meshing with the transmission gear 3 315. The sliding column 316 drives the lifting rod 303 to reciprocate by sliding with the connecting groove plate 317 and the lifting rod 303 and the side frame 304. The lifting rod 303 drives the connecting plate 301 and the knocking rod 302 to rise and fall synchronously. The upper surface of the fresh-keeping bag is knocked to break the ice layer on the upper surface of the fresh-keeping bag; at the same time, the lifting rod 303 moves downward and drives the tooth groove 401 to move downward synchronously, and the tooth groove 401 drives the U-shaped rod 403 to rotate upward by meshing with the transmission gear 402, and the U-shaped rod 403 pushes the lifting plate 404 to move upward by sliding with the slide groove 405, and the lifting plate 404 knocks the lower surface of the fresh-keeping bag by driving the knocking plate 406 to move upward synchronously, and the upper knocking component 3 realizes the synchronous knocking of the upper and lower surfaces of the fresh-keeping bag by cooperating with the lower knocking component 4;

[0064] The conveyor belt 1 203 and the conveyor belt 2 204 move the fresh-keeping bag to the flip frame 502 through the placement plate 205. At the same time, the conveyor belt 204 drives the moving plate 501 to move synchronously. When the rack portion 5011 contacts the transmission gear 6 513, the rack portion 5011 drives the transmission gear 5 512 to rotate 180° clockwise by meshing with the transmission gear 6 513 and the transmission gear 5 512 and the transmission gear 6 513. The transmission gear 5 512 drives the rotating rod 2 503 to rotate. The rotating rod 2 503 can flip the fresh-keeping bag in the flip frame 502 by driving the flip frame 502 to rotate synchronously. The reset spring 508 is stressed and stretched, and the flipped fresh-keeping bag will be placed in the corresponding placement plate 505. On the plate 205, after the fresh-keeping belt moves out of 502, the reset spring 508 contracts and drives 502 to rotate 180° counterclockwise, which is convenient for the subsequent flipping operation of the fresh-keeping belt. During the rotation of the transmission gear 512, the guide groove 5012 drives the sliding frame 509 to reciprocate in the horizontal direction by movably abutting with the abutment rod 515, the spring 2 506 abuts with the limit ring 505, and the slide plate 511 and the side groove 510 slide in cooperation. The sliding frame 509 drives the flip frame 502 to move synchronously by abutting with the retaining ring 514. The flip frame 502 drives the fresh-keeping bag to shake back and forth by reciprocating movement, which is convenient for shaking off the crushed ice on the surface of the fresh-keeping bag and preventing the crushed ice from remaining on the surface of the fresh-keeping bag.

[0065] When the turned fresh-keeping bag moves under the blowing hood 6, the blowing hood 6 blows away the crushed ice remaining on the surface of the fresh-keeping bag through high-pressure gas, and at the same time, air-dries the surfaces of conveyor belt 1 203, conveyor belt 2 204 and placement plate 205, so as to facilitate the continuous use of conveyor belt 1 203 and conveyor belt 2 204 and increase the service life of the device.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
