Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, specifically a vacuum device for food processing. Background Technology

[0002] Vacuum packaging machines, also known as depressurized packaging, remove all air from packaging containers and seal them, maintaining a high degree of depressurization inside the bag. The scarcity of air creates a low-oxygen environment, depriving microorganisms of the conditions for survival, thus ensuring food freshness and preventing spoilage. Automatic vacuum packaging equipment is often used in the processing of some ready-to-eat or fast-food products to vacuum and seal food packaging bags.

[0003] The position of the packaging bag limiting component on the existing rolling vacuum packaging machine cannot be adjusted, and different sizes of food packaging bags cannot be placed. At the same time, the lack of restriction on the packaging bags on the existing vacuum packaging machine makes it easy for the packaging bags to move during vacuum packaging, which makes it impossible to heat seal the packaging bags properly and affects the vacuum packaging effect. Utility Model Content

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only some embodiments, not all embodiments. Based on the embodiments described, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection. Example

[0018] Please see Figure 1-3 A vacuuming device for food processing includes a main body 1, hydraulic rods 2 fixedly installed on both sides of the main body 1, a vacuum packaging machine 3 fixedly installed on the upper end of the hydraulic rods 2, a conveyor belt 4 installed inside the main body 1, a clamping plate 5 installed on the surface of the conveyor belt 4, a fixing frame 6 fixedly installed on both sides of the clamping plate 5, a tension spring 7 fixedly installed on the inner wall of the fixing frame 6, a connecting plate 8 fixedly installed on the upper end of the tension spring 7, a first pulling rod 9 rotatably installed on the upper surface of the connecting plate 8, a sliding plate 10 fixedly installed on the outer side of the first pulling rod 9, a sliding groove 11 opened on the inner wall of the fixing frame 6, a clamping groove 12 opened on the inner wall of the upper end of the fixing frame 6, a clamping post 13 fixedly installed on the surface of the connecting plate 8, the sliding plate 10 and the sliding groove 11 are slidably connected, a slide rail 14 is installed on the surface of the conveyor belt 4, and a limiting plate 15 is slidably installed on the surface of the slide rail 14.

[0019] Specifically, the card plate 5 and the limiting plate 15 are two structures that together form a limiting structure for the food packaging bag. The back of the food packaging bag rests against the limiting plate 15, and then the opening of the food packaging bag is placed on the card plate 5. The opening of the food packaging bag is then locked and limited by the locking post 13. The limiting plate 15 can move on the slide rail 14, and the distance between the limiting plate 15 and the card plate 5 can be adjusted. The tension spring 7 has high elasticity, so that the locking post 13 will lightly stick to the packaging bag, rather than locking it at the opening, so as not to block the opening of the packaging bag, but only to limit it.

[0020] Preferably, a mounting plate 17 is fixedly installed on the outer side of the limiting plate 15, a second pull rod 18 is slidably installed on the surface of the mounting plate 17, a limiting spring 19 is wound around the outer side of the second pull rod 18, and a pressure plate 20 is fixedly installed on the outer side of the second pull rod 18.

[0021] Specifically, pulling the second lever 18 can move the pressure plate 20, which in turn will compress the limit spring 19.

[0022] Preferably, the surface of the slide rail 14 is provided with a limiting hole 16, and the upper and lower ends of the limiting spring 19 are connected to the lower part of the mounting plate 17 and the upper part of the pressure plate 20.

[0023] Specifically, under the pressure of the limiting spring 19, the lower end of the second pull rod 18 will be inserted into the limiting hole 16.

[0024] Working principle: During vacuum packaging, the operator manually pulls the first pull rod 9 upwards. The connecting plate 8 causes the slide plate 10 to slide within the groove 11. Simultaneously, the connecting plate 8 moves the locking post 13 upwards, pulling the tension spring 7 upwards. After reaching the upper end, the operator rotates the first pull rod 9, causing the slide plate 10 to rotate and enter the locking groove 12. The slide plate 10 is then locked in the locking groove 12, positioning the first pull rod 9 and pulling up the locking post 13. The operator then places the food packaging bag between the locking plate 5 and the limiting plate 15, with the front of the bag on the locking plate 5. After placing multiple bags, the operator rotates the first pull rod 9 again, causing the slide plate 10 to rotate into the groove 11. Then, under the pull of the tension spring 7, the connecting plate 8 moves downwards, and the locking post 13 locks the packaging bag, thus restricting its movement. The conveyor belt 4 then starts moving. The hydraulic rod pulls the packaged food into the vacuum packaging machine 3. The vacuum packaging machine 3 moves downward to cover the food, and then the vacuum is evacuated. After completion, the conveyor belt 4 moves. After being transported to the rear end of the conveyor belt 4, the food packaging bag will fall off by its own weight. Then, by pulling the second pull rod 18, the second pull rod 18 will drive the pressure plate 20 to move upward. The pressure plate 20 squeezes the limiting spring 19, and the second pull rod 18 will move away from the limiting hole 16. Then the limiting plate 15 can be moved. After adjustment, the second pull rod 18 is released. Under the compression of the limiting spring, the second pull rod 18 will lock into the limiting hole 16 to restrict the limiting plate 15. This allows the position of the limiting plate 15 to be adjusted according to different packaging bags, which is convenient for placing food packaging bags of different sizes. At the same time, it can restrict the packaging bags to prevent them from moving during vacuuming, thus improving the efficiency of food vacuum packaging. Example

[0025] Please see Figure 1-3 A blower plate 21 is fixedly installed at the front of the main body 1 of the device, and a blower pump 22 is fixedly installed on the outside of the main body 1 of the device. The air outlet of the blower pump 22 is connected to a first connecting pipe, and the first connecting pipe is connected to the blower plate 21.

[0026] Specifically, the blower plate 21 is arc-shaped, which can blow air onto the conveyor belt 4 from top to bottom.

[0027] Preferably, a suction plate 23 is fixedly installed at the front of the main body 1 of the device, a filter box 24 is fixedly installed on the front of the suction plate 23, a suction pump 25 is fixedly installed at the front of the main body 1 of the device, and a second connecting pipe is fixedly connected to the suction port of the suction pump 25, the upper end of the second connecting pipe being connected to the inside of the filter box 24.

[0028] Specifically, the suction plate 23 is located at the lower part of the blowing plate 21, while the filter box 24 is a small bag filter device that can filter dust.

[0029] Working principle: When the blower pump 22 is turned on, the blower plate 21 blows out air that can remove dust from the surface of the conveyor belt 4. While the blower plate 21 blows the dust off, the suction pump 25 works, causing the suction plate 23 to generate suction, which can adsorb the blown-off dust into the filter box 24. The dust is filtered through the filter box 24, thereby cleaning the surface of the conveyor belt 4, keeping the surface of the conveyor belt 4 clean, preventing dust from contaminating the food, and improving the quality of food packaging.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
