Description

Technical Field

[0001] The invention relates to the technical field of vacuum packaged food production, in particular to a vacuum packaged food preselection device. Background Art

[0002] When food is placed in the air, it will undergo various changes (such as corruption, rancidity, discoloration, drying or moisture absorption, etc.), making it inedible. In addition to its own reasons, food deterioration is also closely related to the environmental conditions in which it is located. These environmental conditions mainly include oxygen concentration, humidity, pH value, etc. Therefore, the primary function of composite flexible packaging for food is to reduce the adverse effects of environmental factors on food and prevent food from deteriorating too quickly.

[0003] Bloating is a common problem in vacuum packaging, which will affect the shelf life and product quality of vacuum-packed food. The main reasons for bloating in vacuum packaging bags are: the vacuum degree does not meet the requirements during vacuuming, air remains in the packaging bag, and the gas expands after heating, causing bloating; the seal is not good after vacuuming, or the packaging is damaged or airtight; the food in the packaging bag is not sterilized or sterilized incompletely, and microbial metabolism produces gas, causing bloating.

[0004] The patent with publication number CN205087196U discloses a vacuum-packed food pre-selection device, including a separation tank, a collection tank, a guide rail, a push rod and a pulley. The collection tank is arranged on one side of the separation tank, and an air-drying box is arranged on the other side of the separation tank. A parallel guide rail is arranged on the inner wall of the separation tank, and the pulley is set in the guide rail, and the push rod is installed on the pulley. The packaged vacuum-packed food to be screened is poured into the separation tank, and water is injected into the separation tank. The liquid level is level with the guide rail, and the inflated food vacuum packaging bag will float to the surface of the water. The push rod is pushed to make the pulley slide along the guide rail. The push rod pushes the inflated food vacuum packaging bag that has emerged from the water surface into the collection tank, and the vacuum-packed food that has not been inflated sinks below the liquid surface and enters the air-drying box for air drying. The inflated food vacuum packaging bag in the collection tank can be manually fished out for secondary processing or waste treatment.

[0005] The above technical solution can select problematic foods that are well sealed but still have flatulence by washing and selecting, but it cannot accurately select problematic foods that have flatulence due to damaged packaging bags, because foods with damaged packaging bags will slowly sink to the bottom after being soaked in water. If they are not picked up before they float, the above solution cannot separate the foods with damaged packaging bags, resulting in large errors in pre-selection. Therefore, a vacuum-packaged food pre-selection device is urgently needed to solve the above problems. Summary of the invention

[0029] See also Fig.15 , Fig.16 , Fig.17 , Fig.18 Two electric telescopic columns 605 are embedded and installed in the middle of the lower surface of the base 603; The outer side of the rotating column 601 is provided with a belt mechanism 7, which includes two second belt pulleys 701 movably sleeved on the rotating column 601, and the outer side of each second belt pulley 701 is wound with a second pull rope 702, and one end of the second pull rope 702 away from the second belt pulley 701 is fixedly connected to the outer column 202, and the second pull rope 702 corresponds to the overlap rope pad 103; A lever 703 is evenly and equidistantly fixedly connected between the two second pulleys 701 . When the electric telescopic column 605 is extended, the lever 703 and the electric telescopic column 605 are engaged.

[0030] The working principle of the present invention is as follows: The vacuum-packed foods are uniformly poured into the water tank 101, and the synchronous motor 602 is started to drive the shaft column 301 to rotate through the belt 604. The through groove 309 supported by the shaft column 301 and the partition column 306 moves under the drive, and the vacuum-packed foods inside the water tank 101 are moved and washed, so that the vacuum-packed foods are fully in contact with clean water, which cleans the vacuum-packed foods and improves the cleaning power of the device.

[0031] By cleaning the vacuum-packed food, water will enter the food with a broken bag problem and it will sink to the bottom like normal packaged food. However, the bulging bag food without a broken bag problem will float on the clean water surface due to the gas inside it. The electric telescopic column 605 is retracted to release its clamping on the lever 703, and the lever 703 is rotated clockwise to drive the second pulley 701 to reel in the second pull rope 702. Through the connection between the second pull rope 702 and the outer column 202, the sieve plate 201 is tilted and pulled along the inclined rod 113 to move, so that the bulging bag food floating on the clean water is pushed to the outside of the water tank 101, thereby completing the initial screening process of the pre-selection device. Furthermore, through the hollowing and tilting setting of the sieve plate 201, the food can be drained simultaneously when the problematic food is pushed, which can reduce the loss of clean water inside the water tank 101 and effectively save water resources.

[0032] The screen plate 201 and the rope buckle 307 are connected by the first pull rope 203. Under such working effect, when the screen plate 201 moves along the inclined rod 113 to the edge of the extension plate 104, the partition column 306 of the screen belt mechanism 3 is tilted and lifted with the shaft column 301 as the axis under the action of the tension, and finally the through groove 309 is connected to the stand 105 to form a conveying platform (such as Figure 3 As shown), during the initial screening process, the food retained at the bottom of the water tank 101 is simultaneously transported to improve the working efficiency of the device.

[0033] Through the inclined placement of the inclined rod 113, when the force on the lever 703 is removed, the screen plate 201 can automatically slide back to its original position along the inclined rod 113 under the action of gravity, and the first pull rope 203 loses its tension. The screen belt mechanism 3 can also automatically return to its original position under the action of gravity, thereby improving the automatic return performance of the device.

[0034] After the screening belt mechanism 3 is lifted to transport the food at the bottom of the water tank 101, the door panel 111 is lifted and lowered to continuously transport individual foods to the receiving plate 403 for secondary screening. When normal foods fall onto the receiving plate 403, since no water enters the receiving plate, its gravity cannot shorten the elastic telescopic column 402. Under the obstruction of the cross bar 405, the receiving plate 403 slides to the other end of the bottom rail 401, and deflects after losing the obstruction of the cross bar 405. Finally, it is dried and transported out by the heating plate 507 of the conveying mechanism 5. When the broken bag foods pass through the receiving plate 403, clean water leaks from the inside, causing their weight to increase, thereby directly causing the receiving plate 403 to sink to avoid the obstruction of the cross bar 405, directly causing the receiving plate 403 to deflect, and finally transported out through the conveying mechanism 5. The secondary screening of the second screening mechanism 4 can effectively distinguish between broken bags and normal foods, thereby improving the pre-selection capability of the device.

[0035] By setting the receiving plate 403 in a V shape and placing it on both sides of the conveying mechanism 5, when a single food falls into the receiving plate 403 for secondary screening, the probability of the receiving plate 403 deflecting to the left and right is the same, so that the food can be diverted by automatic deflection, thereby improving the smoothness of the secondary screening and unloading of the device.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
