Description

Technical Field

[0001] The present invention relates to the technical field of vacuum-packed food production, and specifically to a preselection device for vacuum-packed food. Background Art

[0002] When food is placed in the air, various changes (such as spoilage, rancidity, discoloration, drying or moisture absorption, etc.) will occur, resulting in inedibility. In addition to its own reasons, food deterioration also has a great relationship with the environmental conditions it is in. These environmental conditions mainly include oxygen concentration, humidity, pH value, etc. Therefore, as 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] Gas swelling is a common problem in vacuum packaging, which will affect the shelf life and product quality of vacuum-packed food. The main reasons for the appearance of gas swelling in vacuum packaging bags are as follows: when evacuating, the vacuum degree does not meet the requirements, there is residual air in the packaging bag, and gas expands after heating, resulting in gas swelling; after evacuation, the sealing is not good, or the packaging is damaged and air permeates; the food in the packaging bag is not sterilized or the sterilization is not thorough, and microorganisms metabolize to produce gas, resulting in gas swelling.

[0004] The patent with the publication number CN205087196U discloses a preselection device for vacuum-packed food, including a separation tank, a collection tank, guide rails, a push rod and pulleys. The collection tank is arranged on one side of the separation tank, and a drying and boxing device is arranged on the other side of the separation tank. Parallel guide rails are arranged on the inner wall of the separation tank, the pulleys are sleeved in the guide rails, and the push rod is installed on the pulleys. Pour the packaged vacuum-packed food to be screened into the separation tank, inject water into the separation tank, and the liquid level is flush with the guide rails. The vacuum packaging bags of the gas-swollen food will float on the water surface. Push the push rod to make the pulley slide along the guide rail, and the push rod will push the vacuum packaging bags of the gas-swollen food floating out of the water surface into the collection tank. The non-gas-swollen vacuum-packed food sinks below the liquid level and enters the drying and boxing device for drying. The vacuum packaging bags of the gas-swollen food in the collection tank can be manually fished out for secondary processing or waste treatment.

[0005] The above technical solution can select the problem foods with good sealed packaging bags but still gas-swollen through the washing method, but it cannot accurately select the problem foods with gas swelling caused by damaged packaging bags. Because the foods with damaged packaging bags will slowly sink to the bottom after soaking in water. If they are not fished out before they float, the foods with damaged packaging bags cannot be separated by the above solution, resulting in a large error in preselection. Therefore, there is an urgent need for a preselection device for vacuum-packed food to solve the above existing problems. Summary of the Invention

[0021] A first pull rope is fixedly connected to two corners of the upper side of one side surface of the sieve plate, and one end of the first pull rope away from the sieve plate is fixedly bolted to the rope buckle.

[0022] As a preferred technical solution of the present invention, through grooves for enhancing the bearing capacity are uniformly and equidistantly provided on the surface of the screen belt.

[0023] As a preferred technical solution of the present invention, the second screening mechanism includes a bottom rail, on which an elastic telescopic column is slidably inserted, and the upper end of the elastic telescopic column is movably hinged to a V-shaped connecting plate through a torsion spring, and the connecting plate is directly facing between the two baffles;

[0038] A preselection device for vacuum-packed food, through the inclined placement of the inclined rod, when the force applied to the dial rod is removed, under the action of gravity, the sieve plate can automatically slide back to its original position along the inclined rod, and the first pulling rope loses the pulling force. The sieve belt mechanism can also automatically return to its original position under the action of gravity, improving the automatic return performance of the device.

[0039] A preselection device for vacuum-packed food can effectively distinguish between damaged bags and normal foods through the secondary screening of a two-screen mechanism, improving the preselection ability of the device.

[0040] A preselection device for vacuum-packed food, when a single food falls into the receiving plate for secondary screening, the probability of the receiving plate deflecting left and right is the same, so that the diversion of food feeding can be carried out through automatic deflection, improving the smoothness of the secondary screening and feeding of the device.

[0076] See also Figure 8 The surface of the screen belt 308 is evenly and equidistantly provided with through grooves 309 for enhancing the bearing capacity.

[0077] See also Figure 2 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 The second screening mechanism 4 includes a bottom rail 401, on which an elastic telescopic column 402 is slidably inserted. The upper end of the elastic telescopic column 402 is movably hinged with a V-shaped connecting plate 403 through a torsion spring, and the connecting plate 403 is directly between the two baffles 108;

[0085] The two conveyor belts 509 correspond to the two extreme positions of the connecting plate 403 respectively;

[0086] The conveying mechanism 5 drives the conveyor belt 509 through the rotating motor to convey the food falling off the receiving plate 403 in a direction away from the second screening mechanism 4.

[0087] See also Figure 15 、 Figure 16 、 Figure 17 、 Figure 18 Two electric telescopic columns 605 are embedded in the middle of the lower surface of the base 603;

[0088] The outer side of the rotating column 601 is provided with a belt mechanism 7, which includes two second pulleys 701 movably connected to the rotating column 601. A second pull rope 702 is wound around the outer side of each second pulley 701. The end of the second pull rope 702 away from the second pulley 701 is fixedly connected to the outer column 202. The second pull rope 702 corresponds to the overlapping rope pad 103.

[0089] There are evenly fixed connecting rods 703 between two second belt pulleys 701 at equal distances. When the electric telescopic column 605 extends, the connecting rod 703 and the electric telescopic column 605 are clamped together.

[0090] The working principle of the present invention is as follows:

[0091] Pour the vacuum-packed foods into the water tank 101 uniformly. Start the synchronous motor 602 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, stirring and rinsing the vacuum-packed foods inside the water tank 101, making the vacuum-packed foods fully contact with the clear water, playing a role in cleaning the vacuum-packed foods, and improving the cleaning power of the device.

[0092] By cleaning the vacuum-packed foods, the foods with bag-breaking problems will have water entering their interiors and will show the same phenomenon of sinking to the bottom as normal packaged foods. For the expanded bag foods without bag-breaking problems, they will float on the surface of the clear water under the action of the gas inside them. Release the clamping of the connecting rod 703 by the electric telescopic column 605, and rotate the connecting rod 703 clockwise to drive the second belt pulley 701 to wind up the second pulling rope 702. Through the connection between the second pulling rope 702 and the outer column 202, the sieve plate 201 is tilted and pulled along the inclined rod 113 to move, so as to push the expanded bag foods floating on the clear water to the outside of the water tank 101, thus completing the preliminary screening process of the preselection device. Moreover, through the hollow and inclined setting of the sieve plate 201, water drainage of the foods can be carried out synchronously when pushing the problematic foods, reducing the loss of clear water inside the water tank 101 and effectively saving water resources.

[0093] Connect the sieve plate 201 and the rope buckle 307 through the first pulling rope 203. Under such working effects, when the sieve plate 201 moves along the inclined rod 113 to the edge of the extension plate 104, the partition column 306 of the sieve belt mechanism 3 is tilted and lifted with the shaft column 301 as the axis under the action of the pulling force, and finally the through groove 309 is docked with the standing platform 105 to form a conveying platform (as Figure 3 shown), so as to convey the foods remaining at the bottom of the water tank 101 synchronously during the preliminary screening process, improving the working efficiency of the device.

[0094] Due to the inclined placement of the inclined rod 113, when the force applied to the connecting rod 703 is removed, under the action of gravity, the sieve plate 201 can automatically slide back to its original position along the inclined rod 113, and the first pulling rope 203 loses the pulling force. The sieve belt mechanism 3 can also automatically return to its original position under the action of gravity, improving the automatic return performance of the device.

[0095] 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 there is no water inside it, its gravity cannot cause the elastic telescopic column 402 to shorten. 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 through the heating plate 507 of the conveying mechanism 5. When the broken bag food passes through the receiving plate 403, clean water leaks from it, causing its weight to increase, which directly causes 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 by the second screening mechanism 4 can effectively distinguish between broken bags and normal foods, thereby improving the pre-selection capability of the device.

[0096] By the V-shaped setting of the receiving plate 403 and the placement 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 discharge can be diverted by automatic deflection, thereby improving the smoothness of the secondary screening and discharge of the device.

[0097] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
