Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and more specifically, to a vacuum packaging device. Background Technology

[0002] Vacuum packaging equipment is a machine used to package products in a vacuum environment. It mainly consists of a vacuum system, an air-filling and sealing system, a heat-sealing system, and an electrical control system. This equipment can extract the air from the packaging bag to create a low-vacuum environment, inhibiting the growth of bacteria and other microorganisms and preventing oxidation, mold, and spoilage of the goods. At the same time, for some soft items, vacuum packaging can reduce the packaging volume, facilitating transportation and storage.

[0003] During the packaging process, the materials tend to concentrate at the bottom of the bag. After vacuuming, the materials clump together at the bottom, resulting in an uneven and unsightly appearance after packaging, which affects storage and transportation.

[0004] There are many existing technologies for packaging equipment, such as:

[0005] Chinese Patent Application No. 202420038982.2 discloses a vacuum packaging machine with a feeding mechanism. After the vacuum packaging machine completes the vacuum packaging of agricultural products, the drive motor on the right side of the horizontal plate can be activated. The drive motor drives the output end to rotate the threaded rod via a rotating rod, causing the connecting plate to be pushed to the left through the threaded hole on the side wall along the threaded rod. During this movement, the feeding plate installed on the left end of the horizontal part of the L-shaped push rod on the top surface pushes the packaging bag on the vacuum packaging machine to the left until the packaging bag falls into the collection frame on the left. Then, the feeding plate returns to its original position on the right. During this process, packaging bags containing agricultural products can be placed on the vacuum packaging machine. Thus, the feeding mechanism enables rapid material removal after the vacuum packaging machine completes the vacuum packaging of agricultural products.

[0006] However, in existing vacuum packaging equipment, the material clumps together after vacuuming, resulting in an uneven surface that is inconvenient for transportation and has an unattractive appearance, which is detrimental to sales. When using mold vacuum packaging, various sizes of molds are required, and the molds are inconvenient to store after use. In view of this, we propose a vacuum packaging equipment.

[0008] To achieve the above objectives, this utility model provides a vacuum packaging device, including a housing, a bottom plate inside the housing, a support plate fixedly connected to the top of the bottom plate, a bidirectional multi-section telescopic rod fixedly connected inside the support plate, a movable plate fixedly connected to the end of the bidirectional multi-section telescopic rod, and a baffle fixedly connected to the inner surface of the housing.

[0009] The movable plate moves along the direction of the bidirectional multi-section telescopic rod, so that materials of different widths can be flat on both the left and right sides.

[0010] As a further improvement to this technical solution, the number of movable plates is two on each side, a groove is provided on the outer surface of the movable plate, a slider is slidably connected to the inner wall of the groove, and a first multi-section electric telescopic plate is fixedly connected to the outer surface of the slider.

A rectangular plate is fixedly connected to the outer surface of the second multi-section electric telescopic plate, and the rectangular plate is slidably connected to the inner wall of the slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Vacuum packaging equipment is a machine used to package products in a vacuum environment. It mainly consists of a vacuum system, an air-filling and sealing system, a heat-sealing system, and an electrical control system. This equipment can extract the air from the packaging bag to create a low-vacuum environment, inhibiting the growth of bacteria and other microorganisms and preventing oxidation, mold, and spoilage of the goods. At the same time, for some soft items, vacuum packaging can reduce the packaging volume, facilitating transportation and storage.

[0028] During the packaging process, the materials tend to concentrate at the bottom of the bag. After vacuuming, the materials clump together at the bottom, resulting in an uneven and unsightly appearance after packaging, which affects storage and transportation.

[0029] Please see Figures 1-6As shown, this embodiment provides a vacuum packaging device, including a housing 1. To ensure the packaging device is flat on both sides for easy transportation, the following is specified: a bottom plate 32 is provided inside the housing 1, a support plate 28 is fixedly connected to the top of the bottom plate 32, a bidirectional multi-section telescopic rod 29 is fixedly connected inside the support plate 28, a movable plate 2 is fixedly connected to the end of the bidirectional multi-section telescopic rod 29, and a baffle 11 is fixedly connected to the inner surface of the housing 1. The movable plate 2 moves along the direction of the bidirectional multi-section telescopic rod 29 to make materials of different widths flat on both sides. However, in existing vacuum packaging devices, after vacuuming, the materials clump together, the surface is uneven, which is inconvenient for transportation and has an unattractive appearance, which is not conducive to sales. When using mold vacuum packaging, various molds of different sizes are required, and the molds are inconvenient to store after use.

[0030] The improvement in this embodiment is as follows:

[0031] First, the bidirectional multi-section telescopic rod 29 extends and retracts, causing the moving plate 2 to move left and right. Then, the moving plate 2 can be used to vacuum package materials of different widths. Next, the slider 24 slides back and forth, causing the first multi-section electric telescopic plate 25 to move back and forth. The first multi-section electric telescopic plate 25 can be used to vacuum package materials of different lengths. The moving plate 2 and the baffle 11 can make the vacuum packaged items flat from left to right. The first multi-section electric telescopic plate 25 can make the vacuum packaged items relatively flat from front to back, making the surface of the material flat and beautiful, which is conducive to sales and transportation. It can make materials of different lengths and widths flat for vacuum packaging.

[0032] To ensure that the front and back sides of materials of different widths are as flat as possible, two movable plates 2 are used on each side. The outer surface of the movable plate 2 is provided with a groove 22, and a slider 24 is slidably connected to the inner wall of the groove 22. The outer surface of the slider 24 is fixedly connected to a first multi-section electric telescopic plate 25. First, the slider 24 slides to drive the first multi-section electric telescopic plate 25 to move. Then, the movement of the first multi-section electric telescopic plate 25 can be adapted to materials of different lengths. Then, the extension and retraction of the first multi-section electric telescopic plate 25 can make the outer surface of the first multi-section electric telescopic plate 25 fit tightly against the baffle 11, which is suitable for materials of different widths and makes the front and back sides as flat as possible, thus achieving the goal of making the front and back sides of materials of different widths as flat as possible.

[0033] To prevent the first multi-section electric telescopic plate 25 from moving arbitrarily, a slot 21 is provided on the inner surface of the movable plate 2. A plug 271 is inserted into the slot 21, and a connecting block 27 is fixedly connected to the outer surface of the plug 271. A double-section electric telescopic plate 26 is fixedly connected to the top of the connecting block 27, and the outer surface of the double-section electric telescopic plate 26 is fixedly connected to the top of the first multi-section electric telescopic plate 25. First, the slot 21 fixes the plug 271, then the plug 271 fixes the connecting block 27, and then the connecting block 27 fixes the double-section electric telescopic plate 26. The double-section electric telescopic plate 26 fixes the first multi-section electric telescopic plate 25, thus preventing the first multi-section electric telescopic plate 25 from moving arbitrarily.

[0034] Secondly, in order to allow the base plate 32 to move upward for easy access to vacuum-packed items, a cylinder 33 is fixedly connected to the bottom of the base plate 32. The bottom of the cylinder 33 is fixedly connected to the bottom of the inner surface of the housing 1. First, the cylinder 33 extends to move the base plate 32 upward, and then the upward movement of the base plate 32 moves the vacuum-packed items upward, thus enabling the base plate 32 to move upward for easy access to vacuum-packed items.

[0035] Considering that the items need to be manually removed after vacuuming, a slot 23 is provided on the outer surface of the moving plate 2. A second multi-section electric telescopic plate 31 is fixedly connected to the inner wall of the slot 23. A rectangular plate 3 is fixedly connected to the outer surface of the second multi-section electric telescopic plate 31. The rectangular plate 3 is slidably connected to the inner wall of the slot 23. First, the second multi-section electric telescopic plate 31 extends and drives the rectangular plate 3 to move outward. Then, the rectangular plate 3 moves outward and drives the vacuumed items to move outward, thus realizing that the vacuumed items do not need to be manually removed.

[0036] In summary, the working principle of this solution is as follows:

[0037] After the material is packed into a packaging bag, it is placed between the moving plate 2 and the baffle 11. The bidirectional multi-section telescopic rod 29 is extended, which causes the moving plate 2 to press towards the baffle 11. After pressing to the ideal width, the first multi-section electric telescopic plate 25 is extended until it fits against the baffle 11. The double-section electric telescopic plate 26 is extended, which causes the connecting block 27 to move towards the support plate 28. The movement of the connecting block 27 towards the support plate 28 causes the insert block 271 to move towards the support plate 28 until the insert block 271 is pulled out of the slot 21. The first multi-section electric telescopic plates 25 on both sides of the material are moved towards the material. After moving to the ideal width, the double-section electric telescopic plate... The first multi-section electric telescopic plate 25 is shortened, which drives the connecting block 27 to move towards the moving plate 2. The moving of the connecting block 27 to the moving plate 2 causes the insert block 271 to be inserted into the slot 21, making it difficult for the first multi-section electric telescopic plate 25 to move back and forth or to the sides, so that the material is relatively flat in all directions. After the material is vacuum-packed, the cylinder 33 is extended, which drives the bottom plate 32 to move upward. The upward movement of the bottom plate 32 causes the material on the bottom plate 32 to move upward. The extension of the second multi-section electric telescopic plate 31 drives the rectangular plate 3 to move outward. The outward movement of the rectangular plate 3 causes the vacuum-packed material to move outward to the conveyor line on the left and right sides of the shell 1, so that the surface of the material is flat and beautiful, which is convenient for transportation, and the vacuum-packed material is easy to take out.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
