Description

Technical Field

[0001] This utility model belongs to the field of cooked food packaging technology, and more specifically, it relates to a rapid packaging device for vacuum cooked food. Background Technology

[0002] When vacuum packaging cooked food, the packaging bag containing the cooked food should first be placed in the packaging area of ​​the vacuum packaging machine, with the bag opening positioned under the sealer. After closing the sealing cover, the vacuum pump should be started. The vacuum pump will extract the air from the vacuum chamber, creating a negative pressure environment. At this time, the air inside the packaging bag will also be gradually extracted under the pressure difference. After vacuuming is completed, the sealer will start to heat the heating strip, and at the same time, the rubber air bladder will inflate and press the packaging bag tightly onto the heating strip. At this time, the plastic film at the sealing point of the packaging bag will melt, completing the packaging.

[0003] For example, CN213832405U discloses a rapid sealing device for cooked food packaging, including a vacuum sealer. A connecting rod is movably connected through the upper end of the vacuum sealer, and connecting seats are provided at both the front and rear of the connecting rod. The connecting seats are symmetrically arranged on the connecting rod, and the lower end of the connecting seat has a recessed portion. Grooves are provided on the left and right sides of the vacuum sealer, and connecting blocks are slidably arranged in the grooves. By utilizing the convenience of the connecting rod moving up and down and the all-round wrapping of the cover, it can not hinder the normal operation of the vacuum sealer, and can also effectively protect it from dust when we are not using the equipment. When the spring buckle retracts into the connecting rod, we simultaneously pull the connecting post down, so that the spring buckle is locked into the groove, and then continue to lower the connecting rod.

[0004] Based on the above, during the vacuum packaging process, workers may accidentally open the sealing cap prematurely due to operational errors, resulting in residual air inside the packaging bag, which disrupts the vacuum environment, affects the packaging effect on cooked food, and requires the damaged packaging to be picked out and repackaged, thus affecting packaging efficiency.

[0021] The transmission structure includes limiting transmission gears 102 and limiting transmission racks 103; multiple limiting transmission gears 102 are provided, and the multiple limiting transmission gears 102 are fixedly connected to the outside of multiple position limiting blocks 5 respectively; multiple limiting transmission racks 103 are provided, and the multiple limiting transmission racks 103 are evenly distributed and slidably connected to the front and rear sides of the packaging machine body 1; the multiple limiting transmission gears 102 mesh with the multiple limiting transmission racks 103 respectively.

[0022] The transmission structure also includes guide mounting blocks 104 and first reset elastic elements 106. Multiple guide mounting blocks 104 are provided, and multiple guide mounting blocks 104 are fixedly connected to the upper side of multiple limit transmission racks 103 respectively.

Multiple first reset elastic elements 106 are provided, and multiple limit transmission racks 103 are elastically connected to the packaging machine body 1 through multiple first reset elastic elements 106.

[0023] The transmission structure also includes a limiting electromagnet 101 and a first limiting metal block 105; multiple limiting electromagnets 101 are provided, and the multiple limiting electromagnets 101 are evenly distributed and fixedly connected to the front and rear sides of the main body 1 of the packaging machine; multiple first limiting metal blocks 105 are provided, and the multiple first limiting metal blocks 105 are respectively fixedly connected to the lower part of multiple guide mounting blocks 104; a vacuum pump is provided inside the main body 1 of the packaging machine, and the control circuits of the multiple limiting electromagnets 101 are all connected in series with the control circuit of the vacuum pump.

[0024] The specific usage and function of this embodiment: When using a vacuum packaging machine to package cooked food, first place the prepared packaging bag under the sealer, close the packaging area sealing cover 3, at this time the limiting transmission rack 103 is covered in the position limiting groove 4, the limiting connecting rod 2 can connect and limit the packaging area sealing cover 3, start the vacuum pump to evacuate the inside of the packaging area sealing cover 3, the rubber sealing gasket can compensate for the gap between the packaging area sealing cover 3 and the main body 1 of the packaging machine, when the vacuum pump is started, the limiting electromagnet 101 is also started, at this time the limiting electromagnet 101 generates magnetic force to attract the first limiting metal block 105, the first limiting metal block 105 moves downward, driving the limiting transmission rack 103 to slide downward. When the limiting transmission rack 103 slides downward, it will push the limiting transmission gear 102 and the position limiting block 5 to rotate. After the upper part of the limiting transmission rack 103 is flush with the upper part of the packaging machine body 1, the position limiting block 5 will rotate into the position limiting groove 4. The position of the limiting transmission rack 103 is fixed by the attraction force of the limiting electromagnet 101 and the first limiting metal block 105. The guide mounting block 104 can guide the movement of the limiting transmission rack 103. After the packaging is completed, the vacuum pump stops working and the limiting electromagnet 101 is de-energized at the same time. At this time, the sealing cover 3 of the packaging area can be opened. The first reset elastic element 106 will push the limiting transmission rack 103 to reset, and at the same time drive the limiting transmission gear 102 to reverse so that the position limiting block 5 is reset.

[0025] Example 2: As attached Figure 2 To be continued Figure 5 As shown: Based on Embodiment 1, a limiting structure is also included; the limiting structure is disposed on the upper part of the main body 1 of the packaging machine.

[0026] The limiting structure includes a limiting slot 401 and a positioning electromagnet 402. Multiple limiting slots 401 are provided, and the multiple limiting slots 401 are respectively opened inside the multiple position limiting slots 4. Multiple positioning electromagnets 402 are provided, and the multiple positioning electromagnets 402 are respectively fixedly connected to the inside of the multiple limiting slots 401. The control circuits of the multiple positioning electromagnets 402 are all connected in series with the control circuit of the vacuum pump.

[0028] The specific usage and function of this embodiment are as follows: When the vacuum pump is started, the positioning electromagnet 402 is also activated. After the position limiting block 5 rotates into the position limiting groove 4, the magnetic force generated by the positioning electromagnet 402 will attract the second limiting metal block 602, causing the second limiting metal block 602 to drive the limiting card block 6 to slide along the position limiting block 5 until the limiting card block 6 moves into the limiting card groove 401. At this time, the second limiting metal block 602 and the positioning electromagnet 402 are in contact to fix the position of the limiting card block 6. At this time, the operator cannot pull the packaging area sealing cover 3, which effectively avoids the situation where the packaging area sealing cover 3 is opened prematurely due to misoperation. When the vacuum pump stops working, the positioning electromagnet 402 is de-energized, and the second reset elastic element 601 will pull the limiting card block 6 to reset. At this time, the packaging area sealing cover 3 is no longer limited and can be easily opened.
