Description

Technical Field

[0001] The present application relates to the technical field of food processing, and in particular to a food vacuum packaging device. Background Art

[0002] Vacuum packaging is to extract all the air in the packaging container and seal it, maintaining the bag in a highly reduced pressure state. The scarce air is equivalent to the low oxygen effect, which makes it impossible for microorganisms to survive, so as to achieve the purpose of keeping food fresh and free from disease and decay. Food that has been vacuum packed can be transported over long distances and stored for a long time.

[0003] When an existing vacuum packaging machine vacuum-packs food, a food packaging bag containing the food is placed on a hot pressing strip in a vacuum chamber, and the air in the food packaging bag is extracted by a vacuum pump. After a predetermined vacuum degree is reached, the hot pressing strip is used to complete the sealing process. In the process of vacuuming the food packaging bag, the discharge of air in the food packaging bag may cause the food packaging bag to partially shrink and the bag opening to be uneven, resulting in air leakage and material leakage in the sealed food packaging bag, thereby reducing the food packaging effect and affecting the food safety.

In addition, one end of the bidirectional screw 402 passes through the corresponding connecting block 401 and is connected to the output shaft of the driving motor disposed on the connecting block 401, and then the bidirectional screw 402 is driven to rotate forward or reversely by the driving motor.

[0027] Furthermore, a rubber strip is provided at the bottom of the smoothing plate 403, so as to prevent the bottom of the smoothing plate 403 from contacting the food packaging bag and causing scratches on the food packaging bag during the process of smoothing the food packaging bag.

[0028] The vacuum cover 500 is disposed on the vacuum packaging machine 100 and can be combined with the packaging platform 101 to form a vacuum chamber for accommodating food packaging bags. The vacuum cover 500 is connected to the vacuum pump 102 on the vacuum packaging machine 100 through a vacuum tube 501 . In the process of vacuum packaging, the food packaging bag, the first hot pressing strip 200 and the smoothing and clamping mechanism 400 are all in the vacuum chamber. The vacuum pump 102 is turned on and the air in the vacuum chamber and the food packaging bag is extracted through the vacuum tube 501 by the vacuum pump 102, so that the food packaging bag containing food is in a vacuum state, thereby realizing the vacuuming of the food packaging bag.

During the movement, the bag mouth of the food packaging bag is smoothed by the smoothing plate 403, and the two smoothing plates 403 are used to smooth the opposite sides of the bag mouth of the food packaging bag. The food packaging bag is clamped and then a vacuum chamber for accommodating the food packaging bag is formed by the vacuum cover 500 and the packaging platform 101. The air in the vacuum chamber and the food packaging bag is extracted through the vacuum tube 501 by the vacuum pump 102, so that the food packaging bag containing food is in a vacuum state. The bag opening of the food packaging bag is then heat-pressed and sealed by the first hot pressing strip 200, and the two smoothing plates 403 clamp the opposite sides of the food packaging bag to make the above-mentioned vacuuming process more stable. The food packaging bag smoothed by the two smoothing plates 403 has better sealing after heat-pressing and sealing by the first hot pressing strip 200, avoiding problems such as air leakage and material leakage, ensuring the effect of food packaging, and improving the safety of food consumption.

[0031] In the above embodiment, before placing the food packaging bag containing food on the packaging platform 101, Figure 3 For example, the pressing rod 201 is rotated clockwise so that the top of the pressing rod 201 is located above the first hot strip 200, so that there is a certain vertical distance between the top of the pressing rod 201 and the upper surface of the first hot strip 200, which can be used to place the food packaging bag on the first hot strip 200, and the food packaging bag is placed on the packaging platform 101 with the bag opening of the food packaging bag set on the upper surface of the first hot strip 200, and then the pressing rod 201 is rotated counterclockwise to Figure 3 In the state shown, the food packaging bag is fixed between the pressure rod 201 and the upper surface of the packaging platform 101, so that the pressure rod 201 fixes the food packaging bag, thereby improving the packaging efficiency of the food packaging bag and the stability of the packaging process.

[0032] In some embodiments, reference Figure 3 The width of the first hot pressing strip 200 in the present application is greater than the width of the smoothing plate 403, and a first heating element is arranged in the first hot pressing strip 200; wherein, the first heating element is arranged in the first hot pressing strip 200 and is parallel to the bidirectional screw 402, and the first heating element can be a heating wire, a heating rod, etc., which can be set according to actual needs. Therefore, the present application does not make specific limitations on it.

[0033] A hot pressing block 502 corresponding to the first hot pressing strip 200 is arranged in the vacuum cover 500, and a second heating element corresponding to the first heating element is arranged in the hot pressing block 502. The length of the hot pressing block 502 on the vacuum cover 500 matches the length of the first hot pressing strip 200, and the second heating element can be a heating wire, a heating rod, etc., which can be set according to actual needs, so this application does not specifically limit it here.

[0034] In the above embodiment, when the vacuum hood 500 and the packaging platform 101 form a vacuum chamber (at this time, the first hot pressing strip 200 and the smoothing clamping mechanism 400 are located in the vacuum chamber), the lower surface of the hot pressing block 502 contacts the upper surface of the food packaging bag, and the upper surface of the first hot pressing strip 200 contacts the lower surface of the food packaging bag, thereby using the second heating element in the hot pressing block 502 (wherein the hot pressing block 502 is located on the inner top surface of the vacuum hood 500 and extends along the length direction of the vacuum hood 500) and the second heating element in the first hot pressing strip 200 to perform simultaneous hot pressing and sealing of the food packaging bag from top to bottom, thereby improving the efficiency of hot pressing and sealing, while ensuring the sealing of the food packaging bag after hot pressing and sealing, avoiding problems such as air leakage and material leakage, ensuring the effect of food packaging, and improving the safety of food consumption.

[0035] In some embodiments, reference Figure 1 and Figure 2 In the present application, opposite sides of the vacuum hood 500 are connected to the vacuum packaging machine 100 through two connecting rods 503. The two connecting rods on the same side of the vacuum packaging machine 100 are arranged at intervals, which improves the stability of the connection between the vacuum hood 500 and the vacuum packaging machine 100. The two ends of each connecting rod 503 are rotatably connected to the vacuum hood 500 and the vacuum packaging machine 100 respectively.

[0036] In some embodiments, reference Figure 1, the packaging platform 101 in the present application is provided with a second hot strip 1011 coaxially arranged on the packaging platform 101 with the first hot strip 200, and the second hot strip 1011 is spaced apart from the first hot strip 200. Among them, the distance between the second hot strip 1011 coaxially arranged with the first hot strip 200 can be set according to actual needs, the purpose is to ensure that the vacuum cover 500 can form a receiving cavity with the packaging platform 101 to accommodate the food packaging bag placed on the first hot strip 200 or the food packaging bag placed on the second hot strip 1011, therefore, the present application does not make specific restrictions on it here. Since the vacuum cover 500 is rotatably connected to the vacuum packaging machine 100 through the connecting rod 503, the vacuum cover 500 can be moved in an arc direction. During the movement of the vacuum hood 500, it can form a accommodating cavity with the packaging platform 101 to accommodate the food packaging bags placed on the first hot strip 200 or the food packaging bags placed on the second hot strip 1011. When the vacuum hood 500 moves to the first hot strip 200 and vacuum-packs the food packaging bags on the first hot strip 200, the food packaging bags that need to be vacuum-packed are placed on the second hot strip 1011. After the vacuum packaging process of the vacuum packaging bags on the first hot strip 200 is completed, the vacuum hood 500 moves to the second hot strip 1011 and vacuum-packs the food packaging bags on the second hot strip 1011, and then another food packaging bag that needs to be vacuum-packed is placed on the first hot strip 200, thereby improving the efficiency of vacuum packaging of food packaging bags.

[0037] In some embodiments, reference Figure 1 and Figure 2 The outer wall of the vacuum cover 500 in the present application is provided with a handle 504. The vacuum cover 500 is pulled by the handle 504 to move, thereby improving the convenience of moving the vacuum cover 500.

[0038] In some embodiments, reference Figure 3 The adjustment mechanism 300 in the present application includes a telescopic device 301 and a connecting plate 302; specifically, the telescopic device 301 and the connecting plate 302 are respectively arranged on both sides of the length direction of the first hot press strip 200, the telescopic end of the telescopic device 301 is connected to one of the connecting blocks 401, and the connecting plate 302 is provided with a vertical slide groove 3021 for accommodating the other connecting block 401. The telescopic device 301 can be a cylinder, a hydraulic cylinder, etc., which can be set according to actual needs, so the present application does not specifically limit it here.

[0039] In the above embodiment, the telescopic device 301 drives the connecting block 401 connected to its telescopic end to move vertically up and down, and the other connecting block 401 moves vertically up and down in the vertical slide groove 3021 on the connecting plate 302, so as to adjust the vertical distance between the bottom end of the smoothing plate 403 and the food packaging bag on the first hot pressure strip 200. When the food packaging bag needs to be placed on the first hot pressure strip 200, the telescopic device 301 is extended upward so that the bottom end of the smoothing plate 403 is a certain distance away from the upper surface of the first hot pressure strip 200 (this distance can make the food packaging bag be placed on the first hot pressure strip smoothly). When the food packaging bag is placed on the first hot pressure strip 200, the telescopic device 301 is contracted, so that the bottom end of the smoothing plate 403 contacts the food packaging bag on the first hot pressure strip 200, and then the smoothing of the food packaging bag by the smoothing plate 403 is achieved by the rotation of the bidirectional screw 402.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
