Description

Technical Field

[0001] The utility model relates to the technical field of vacuum packaging and belongs to a vacuum packaging machine. Background Art

[0002] To reduce food spoilage, food processing plants typically use vacuum packaging machines to vacuum-pack food. Vacuum-packed food reduces contact with air, making it less likely to spoil and helping protect the health of consumers. For example, in a rice dumpling processing plant, the rice dumplings are first cooked and cooled before being placed in vacuum packaging bags. The bags are then placed in a vacuum packaging machine for vacuum extraction. The principle of a vacuum packaging machine is that once the package is placed in the working area of ​​the vacuum packaging machine, the machine starts, and the vacuum pump begins to work, extracting the air from the package. As the air is continuously extracted, the air pressure inside the package gradually decreases. Once the desired vacuum level is reached, a heat-sealing device seals the package to ensure its tightness.

[0003] For example, the prior art publication number CN212766995U is a fully automatic stretch film vacuum packaging machine. The utility model includes a vacuum packaging machine, a vacuum pump, a fixing frame, a driving shaft, two sets of cylinders, a driven shaft and a vacuum sealing cover. The packaging bag is covered by the vacuum sealing cover, and then a vacuum pump is used to achieve vacuum packaging.

[0004] However, the above-mentioned vacuum packaging machine still has the following problems during use: when placing the packaging bag containing the rice dumplings, the opening of the packaging bag is manually pressed onto the heating strip. Since multiple packaging bags are often placed on the heating strip at the same time for packaging in the same batch, loading and unloading the materials one by one is relatively complicated, resulting in low packaging efficiency. Based on this, the utility model provides a vacuum packaging machine with high packaging efficiency. Utility Model Content

[0005] To this end, the utility model provides a vacuum packaging machine to solve the problem of low efficiency of the vacuum packaging machine due to loading and unloading materials one by one in the prior art.

Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by the present utility model.

[0030] Refer to the attached drawings of the specification Figure 1-5 The present utility model provides a vacuum packaging machine, including a vacuum packaging machine main body 1. Heating strips 2 are fixedly provided on both the front and rear sides of the top of the vacuum packaging machine main body 1. Pressing rods 3 are provided on both heating strips 2. A vacuum sealing cover 4 is covered above the vacuum packaging machine main body 1. Supports 5 are fixedly provided on both sides of the vacuum packaging machine main body 1.

[0031] Both the top ends of the two supports 5 are fixedly provided with a feeding mechanism 6. The feeding mechanism 6 includes a C-shaped frame 601. There are two electric sliding tables 602 between the C-shaped frame 601 and the support 5. Installation grooves 10 are opened on both the front and rear sides of the top ends of the two supports 5. The two electric sliding tables 602 are respectively fixed in the two installation grooves 10. The two electric sliding tables 602 are respectively fixed to the outer walls of the front and rear sides of the C-shaped frame 601. The C-shaped frame 601 is driven to move by the electric sliding tables 602, so as to achieve automatic feeding and discharging. A belt conveyor 603 for conveying packaging bags containing zongzi is installed inside the C-shaped frame 601.

[0032] On one side of the C-shaped frame 601 close to the vacuum packaging machine main body 1, a material pushing mechanism 7 is rotatably connected. The material pushing mechanism 7 includes a push plate 701. The push plate 701 is arranged between the C-shaped frame 601 and the vacuum sealing cover 4. With the help of the push plate 701, automatic blanking of zongzi on the vacuum packaging machine main body 1 can be achieved. On both the front and rear sides of the push plate 701, connecting plates 702 are fixedly arranged. The connecting plates 702 are rotatably connected to the C-shaped frame 601. At the rear ends of the two C-shaped frames 601, motors 703 for driving the connecting plates 702 to rotate are fixedly arranged. The output shaft of the motor 703 is fixed to the rear end of the connecting plate 702. With the help of the motor 703 and the connecting plate 702, the push plate 701 is driven to rotate, without manual operation, which is time-saving and labor-saving in use.

[0033] On one side of the two brackets 5 close to the vacuum packaging machine main body 1, blanking openings 8 are respectively provided. Inside the blanking openings 8, inclined blanking chutes 9 are fixedly arranged. Below the two inclined blanking chutes 9, collecting boxes 12 are arranged.

[0034] During use, the C-shaped frame 601 on the left side of the vacuum packaging machine main body 1 moves towards the vacuum packaging machine main body 1. After the belt conveyor 603 moves between the two heating strips 2, the belt conveyor 603 is rotated, and at the same time, the electric sliding table 602 is used to drive the C-shaped frame 601 to move leftward. The belt conveyor 603 rotates clockwise and moves leftward at the same time, so that the packaging bags containing zongzi fall from the belt conveyor 603 onto the tabletop of the vacuum packaging machine main body 1, completing the automatic feeding of zongzi. After that, the vacuum sealing cover 4 and the vacuum packaging machine main body 1 are closed for vacuum pumping to complete the vacuum packaging of zongzi. After the packaging is completed, the C-shaped frame 601 on the right side moves leftward, and the push plate 701 rotates to the front of the C-shaped frame 601 under the drive of the connecting plate 7 and the motor 703, pushing the vacuum-packed zongzi to the left, so that the zongzi falls into the collecting box 12 through the inclined blanking chute 9 on the left side. Then, the belt conveyor 603 on the right side moves rightward and rotates counterclockwise at the same time to achieve the automatic feeding of zongzi. By repeating the above steps, using the feeding mechanisms 6 on both the left and right sides can not only automatically feed but also automatically blank, releasing human labor, and thus can greatly improve the vacuum packaging efficiency of zongzi.

[0036] A motor 2 16 for driving the pressure rod 3 to rotate is fixedly embedded on one side of the two heating strips 2. The output shaft of the motor 2 16 is fixed to one end of the pressure rod 3. The motor 2 16 is used to drive the pressure rod 3 to rotate automatically, which greatly saves the time of manually moving the pressure rod 3 and thereby improves the vacuum packaging efficiency of the rice dumplings.

[0037] By arranging motor 2 16 on both heating strips 2, motor 2 16 is used to drive the pressure rod 3 to rotate automatically, and there is no need for staff to manually move the pressure rod 3, thereby improving the vacuum packaging efficiency of the rice dumplings, and using the electric push rod 13 to drive the vacuum sealing cover 4 to move up and down, which can save time for opening and closing the cover, and can further improve the packaging efficiency of the rice dumplings.

[0038] Refer to the instruction manual Figure 1-5 The two inclined feeding chutes 9 are both made of transparent acrylic plates. A plurality of rubber strips 11 are fixed on the inner walls of the two inclined feeding chutes 9 on the side away from each other. The plurality of rubber strips 11 are evenly distributed on the inner walls of the inclined feeding chutes 9. The plurality of rubber strips 11 can be used to slow down the speed at which the rice dumplings fall, thereby reducing the amount of damage caused by collision to the rice dumplings.

[0039] By arranging multiple rubber strips 11 in the two inclined feeding chutes 9, the rubber strips 11 are made of soft material, and the multiple rubber strips 11 can slow down the speed at which the rice dumplings fall, thereby preventing the rice dumplings from being damaged by collision due to a fast falling speed. In addition, the inclined feeding chutes 9 are made of transparent acrylic plates, which makes it easy to check the interior of the inclined feeding chutes 9 and clear the blocked rice dumplings.
