Description

Technical Field

[0001] The present invention relates to the technical field of food preservation packaging, and more specifically, to intelligent integrated food preservation packaging equipment. Background Art

[0002] Food preservation is a processing measure taken to prevent food from spoiling and extending its shelf life. Common methods include low temperature preservation, high temperature preservation, dehydration preservation, increasing the osmotic pressure of food, increasing the hydrogen ion concentration of food, irradiation preservation, air isolation, adding preservatives and antioxidants, that is, preserving food through physical and chemical methods.

[0003] However, when food is preserved by plastic wrap, it has the functions of preserving freshness, preventing drying, preventing odor, and facilitating storage. Wrapping plastic wrap on the surface of food can slow down the entry of oxygen and extend the shelf life of food. Plastic wrap can prevent the evaporation of moisture in food and avoid drying and deterioration. If certain foods are wrapped in plastic wrap, they will release odors, but these odors will not spread to other foods. Plastic wrap can help divide food into small portions and make it easier to store.

[0004] When food is preserved by plastic wrap, more residual nitrogen will remain at the injection port when nitrogen is injected into the plastic wrap, resulting in reduced preservation effect and nitrogen waste.

[0034] See also Figures 4 to 6A hole 102 for passing the cling film is provided at the exit of the shell 1, a guide shaft is provided in the hole 102, a conveying member for conveying the cling film is also provided in the hole 102, one end of the conveying member is connected to a motor for driving the conveying member to rotate, wherein the motor is electrically connected to the controller, a telescopic tool for cutting the cling film is also provided in the hole 102, wherein the telescopic tool is electrically connected to the controller, the telescopic tool is a prior art and will not be elaborated herein.

[0035] When in use, first put the items to be packaged into the tray, and then place the tray and the items on the conveyor belt 101, and place them with the rightmost side of the conveyor belt 101 as the reference, and then convey the tray and the items to be packaged to the supporting member 231 through the conveyor belt 101. When there are trays and items on the top of the corresponding supporting member 231, the corresponding pressure sensor monitors the pressure of the supporting member 231 and sends it to the controller. The controller controls the sliding member 32 and the control member 34 to make the sliding member 32 move on the slide rail 31 toward the exit of the shell 1. When the sliding member 32 approaches the hole 102, the controller controls the member 34 to retract so that the clamping member 33 rotates clockwise around the rotating shaft and moves away from the sliding member 32. When the clamping member 33 is located in the hole 102 and is at the rightmost side, the clamping member 33 moves clockwise. When approaching the conveying member, the controller energizes the motor for driving the conveying member to rotate counterclockwise, so that the cling film located above the conveying member is conveyed to the top of the clamping member 33 under the counterclockwise rotation of the conveying member. Similarly, the controller controls the control member 34 to extend the control member 34, and the clamping member 33 clamps the cling film counterclockwise around the rotating shaft. At the same time, the controller analyzes the data of multiple pressure sensors, preliminarily determines the size of the tray, and adjusts the distance of the sliding member 32 away from the outlet of the shell 1, so as to automatically adjust the amount of cling film according to the size of the tray. When the sliding member 32 moves to the appropriate position, the controller controls multiple electric telescopic clamps 35 to extend to the area formed by the sliding member 32 and the slide rail 31. The cling film is clamped, and when the electric telescopic claws 35 retract after clamping the cling film, the cling film clamped by the corresponding electric telescopic claws 35 is pre-stretched. At the same time, the controller controls the telescopic member 23 under the tray to extend the telescopic member 23, so that the supporting member 231 under the tray rises together with the tray. When the items on the tray touch the cling film, the tension of the cling film is monitored by the tension sensor located in the electric telescopic claws 35. The cling film is clamped by multiple electric telescopic claws 35 while further covering the top item on the tray. As the telescopic member 23 extends, the tray and the items continue to press the cling film, and the electric telescopic claws 35 on both sides of the tray follow the telescopic movement. When the electric telescopic jaws 35 are extended to the maximum limit position, the telescopic members 23 on both sides of the pallet are retracted. When the telescopic members 23 are retracted, the corresponding supporting members 231 are driven to move downward. At the same time, the electric telescopic jaws 35 on both sides of the pallet are further extended. The electric telescopic jaws 35 on both sides of the pallet are close to each other. When the electric telescopic jaws 35 are close to each other, they cover both sides of the pallet. When the electric telescopic jaws 35 and the cling film are located at the bottom of the pallet, the electric telescopic jaws 35 are constantly close to each other and gradually release the clamped cling film. At the same time, the pallet is supported by the corresponding electric telescopic jaws 35. At the same time, the telescopic member 23 located in the middle position of the bottom of the pallet is retracted. Synchronously,The telescopic member 23 drives the last supporting member 231 to move downward, and the controller moves the sliding member 32 toward the exit of the shell 1. While the sliding member 32 moves, the clamping member 33 controls the clamping member 33 through the control member 34, so that the sliding member 32 moves to the bottom of the tray and covers the tray on the side of the sliding member 32. While the sliding member 32 drives the tray to move toward the exit of the shell 1, when the tray is pushed onto the shell 1 above the hole 102 by the sliding member 32, the plastic wrap in the hole 102 is cut by the telescopic cutter. At the same time, the sliding member 32 further pushes the tray to move in the exit of the shell 1 above the hole 102, so that the plastic wrap away from the side of the sliding member 32 wraps the tray and the items, completing the packaging, and the cycle is repeated in sequence.

[0036] To summarize, while the pallet and items are being transported by the conveyor belt 101, the corresponding supporting member 231 is monitored by the pressure sensor, so that the distance after the sliding member 32 pulls the cling film can be adjusted by the controller, so that the appropriate length of cling film can be pulled in real time according to the size of the pallet to avoid waste caused by excessive pulling. At the same time, the cling film is pre-stretched by the electric telescopic clamps 35 that cooperate with each other. At the same time, the pulling force of the cling film is timely controlled by the tension sensor to prevent the cling film from breaking due to the items in the pallet being too high.

[0037] Example 2 On the basis of the above embodiment, it is found in actual use that since only plastic wrap is used to wrap the tray containing items, the oxygen content in the air between the tray and the plastic wrap is high, resulting in a short shelf life of the packaged food. This embodiment is specially invented to solve the above problem.

[0038] On the basis of the above-mentioned embodiments, after the plastic wrap passes through the clamping member 33 and the sliding member 32 pulls the plastic wrap to a certain distance, the electric telescopic clamps 35 located on both sides of the plastic wrap further clamp and stretch the plastic wrap, and the controller controls the opening size of the electric shut-off valve according to the distance moved by the sliding member 32, so that the nitrogen located in the storage member 46 enters the multiple air outlet pipes 432 through the outlet and pipeline of the electric shut-off valve, and the nitrogen sprayed from the multiple air outlet pipes 432 is injected into the electric telescopic clamps 35 while further clamping and stretching the plastic wrap, and on the basis of the above-mentioned embodiments, the tray and the items are quickly packaged, and the food in the tray is further preserved by the nitrogen located between the tray and the plastic wrap, thereby increasing the preservation effect and the preservation period.

[0039] Example 3 On the basis of the above embodiments, it was found in actual use that although nitrogen is injected into the cling film after being stretched by the electric telescopic clamp 35 through multiple air outlet pipes 432 to increase the preservation effect, there is still a problem that when nitrogen is injected into the cling film, due to the long distance between the sliding part 32 and the shell 1 outlet of some trays, the nitrogen concentration at the sliding part 32 injected through the air outlet pipe 432 is low. In addition, after multiple air outlet pipes 432 inject nitrogen into the cling film, a large amount of nitrogen will remain at the outlet of the air outlet pipe 432, resulting in the inability to further preserve the food between the tray and the cling film through the air outlet pipe 432 to increase the preservation effect.

[0040] When used on the basis of the above embodiment, when the telescopic member 23 at the bottom of the tray is extended, the supporting member 231 is driven to rise synchronously, and when the supporting member 231 near the first gas cylinder 21 rises, the connecting block 24 is driven to rise synchronously, and when the connecting block 24 rises, the first piston rod 212 is driven to move, and when the first piston rod 212 moves, the first piston 211 is driven to move in the first gas cylinder 21, and when the first piston 211 moves in the first gas cylinder 21, the first piston 211 squeezes the gas at the first piston rod 212 in the first gas cylinder 21, and the compressed air in the first gas cylinder 21 enters the second connecting hole 424 through the first connecting hole 213 and the pipeline, and the compressed air in the second connecting hole 424 enters the inner cavity of the second gas cylinder 42, and the compressed gas in the second gas cylinder 42 continuously squeezes the second piston 421, and when the second piston 421 moves, it drives the second piston rod 422 When the first movable plate 43 is moved, the pull rope 45 in the guide groove of the guide wheel 431 is gradually tightened. With the continuous movement of the first movable plate 43, the guide wheel 431 rotates clockwise under the action of the pull rope 45. At the same time, the pull rope 45 causes the guide wheel 431 to rotate clockwise, and the pull rope 45 pulls the connecting rod 441 to drive the second movable plate 44 to rotate clockwise around the connecting axis. When the elastic member 423 is compressed to the maximum limit position, the angle between the second movable plate 44 and the first movable plate 43 is an acute angle.

[0041] To summarize, while the second piston rod 422 extends to drive the first movable plate 43 to move, the pull rope 45 pulls the connecting rod 441 in the guide wheel 431, so that the second movable plate 44 rotates clockwise around the connecting axis at the hinge with the first movable plate 43, so that the second movable plate 44 and the first movable plate 43 form an acute angle, so that the residual nitrogen located at the air outlet pipe 432 is squeezed toward the plastic wrap by the first movable plate 43 and the second movable plate 44, and the nitrogen located in the plastic wrap is further close to the sliding member 32, thereby increasing the nitrogen content in the plastic wrap at the sliding member 32, further preserving the packaged food, increasing the preservation period, and preventing nitrogen residue at the air outlet pipe 432.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
