Description

Technical Field

[0001] The utility model relates to the technical field of vacuum packaging machines, and more specifically, the utility model relates to a vacuum packaging machine for food preservation. Background Art

[0002] As an important means of modern food preservation, the core value of food vacuum packaging technology lies in effectively removing the air inside the packaging bag to create a low-oxygen or even oxygen-free environment, thereby inhibiting the growth and reproduction of microorganisms, slowing down the oxidation process of food, and significantly extending the fresh-keeping period and shelf life of food. This technology has been extremely widely used in the food industry, covering cooked meat products (such as chicken legs, hams, sausages, grilled fish slices, beef jerky, etc., these foods are often rich in oil and protein and are vulnerable to microbial invasion), pickled products (such as various pickled vegetables, soy products, and preserved fruits, these foods contain relatively high salt or sugar content, although they have a certain anti-corrosion effect, but vacuum packaging can further extend their storage period) to various fresh fruits, vegetables, seafood products and many other fields. However, despite the many advantages of vacuum packaging technology, there are still some challenges in the use of existing food vacuum packaging machines, especially in the placement and positioning of vacuum bags. Due to the wide variety of foods to be vacuum-packed, with different sizes and shapes, this directly leads to problems such as the vacuum bag being prone to deviation, wrinkling, or even damage during the automated or semi-automated packaging process. These problems not only affect the aesthetics of the packaging but also reduce the market competitiveness of the product, so it is necessary to improve and optimize it. Summary of the Utility Model

The bottom of the motor is fixedly installed with a motor fixing block, and the motor fixing block is fixedly installed at the top of the lifting groove.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By setting a fixing plate in the present utility model, when the packaging bag is placed on the top of the pressing block and the fixing plate, first rotate the fixing rod to initially press the packaging bag. When the vacuum compressor presses the pressing rod downward, the pressing rod compresses the spring, and through the suction force of the magnet, the packaging bag is firmly fixed on the top of the fixing plate. When the packaging is completed and the vacuum compressor leaves the surface of the pressing block, just gently lift the pressing rod to remove the packaging bag. Compared with traditional devices, this design avoids the deviation during vacuum packaging operations due to different shapes of foods. The magnetic force adsorption between the magnet and the fixing plate further strengthens the position of the packaging bag, effectively preventing the deviation or deformation of the packaging bag caused by irregular food shapes or internal air pressure changes, thus ensuring the consistency and aesthetics of the packaging quality.

[0013] 2. By starting the motor, the output shaft of the motor drives the pulley located on the back to rotate. The two pulleys rotate synchronously under the connection of the belt. The pulley drives the threaded rod to rotate, causing the threaded rod to drive the lifting plate to move up and down. The lifting plate drives the wheels to move up and down through the connecting plate, realizing the lifting of the wheels. Compared with traditional devices, this design ensures the stability of the machine during operation, realizes flexible movement, and can smoothly adjust the height of the wheels by precisely controlling the rotation speed and direction of the motor, ensuring that the machine can maintain a stable support state on different terrains or work surfaces.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] AsFigures 1 to 6 As shown in the figure, the utility model provides a vacuum packaging machine for food preservation, which includes a machine body 1. A packaging groove 5 is opened at the top of the machine body 1. A partition plate 4 is fixedly installed at the top of the packaging groove 5. Two fixing plates 3 are fixedly installed on both the left and right sides of the partition plate 4. Slide columns 6 are slidably installed inside the left and right ends of the fixing plates 3. Two springs 7 are fixedly installed between the opposite surfaces of the slide columns 6 and the fixing plates 3. The springs 7 are sleeved on the outer surfaces of the slide columns 6.

[0023] The staff places the food packaging bag on the top of the pressing block 2, rotates the fixing rod 9 to press the packaging bag with the fixing rod 9, places the packaging bag on the top of the fixing plate 3, starts the device, the vacuum compressor 22 flips, the vacuum compressor 22 presses down the pressure rod 10, the pressure rod 10 drives the slide column 6 to move downward, the slide column 6 moves downward and compresses the spring 7 between the slide column 6 and the fixing plate 3, making the magnet 8 approach the fixing plate 3. Under the action of magnetic force, the magnet 8 firmly adsorbs the packaging bag on the fixing plate 3, so that the packaging bag is fixed.

[0024] By providing the fixing plate 3, when the packaging bag is placed on the top of the pressing block 2 and the fixing plate 3, first rotate the fixing rod 9 to initially press the packaging bag. When the vacuum compressor 22 presses down the pressure rod 10, the pressure rod 10 compresses the spring 7 and through the suction force of the magnet 8, firmly fixes the packaging bag on the top of the fixing plate 3. When the packaging is completed, the vacuum compressor 22 leaves the surface of the pressing block 2. Just gently lift the pressure rod 10, and the packaging bag can be removed. Compared with the traditional device, this design avoids the deviation during the vacuum packaging operation due to the different shapes of the food. The magnetic adsorption between the magnet 8 and the fixing plate 3 further strengthens the position of the packaging bag, effectively preventing the deviation or deformation of the packaging bag caused by the irregular shape of the food or the change of internal air pressure, thus ensuring the consistency and aesthetics of the packaging quality.

[0025] Among them, a lifting groove 11 is opened inside the bottom of the machine body 1. Two belt pulleys 14 are rotatably installed at the top of the lifting groove 11. A threaded rod 12 is fixedly installed inside the belt pulley 14 located at the front. A lifting plate 18 is threadedly sleeved on the outer surface of the threaded rod 12. A slide rod 13 is slidably installed inside the left side of the lifting plate 18. The slide rod 13 is fixedly installed at the inner top of the lifting groove 11.

[0026] The staff starts the motor 16. The output shaft of the motor 16 drives the belt pulley 14 located at the back to rotate. The two belt pulleys 14 rotate synchronously through the belt 15, so that the belt pulley 14 located at the front drives the threaded rod 12 to rotate. The threaded rod 12 rotates to drive the lifting plate 18 to lift and lower on the outer surfaces of the threaded rod 12 and the slide rod 13. The lifting plate 18 drives the two connecting plates 20 to make lifting and lowering movements. The two connecting plates 20 drive the four wheels 19 to make lifting and lowering movements together.

[0027] By starting the motor 16, the output shaft of the motor 16 drives the pulley 14 located on the back to rotate. The two pulleys 14 rotate synchronously under the connection of the belt 15. The pulley 14 drives the threaded rod 12 to rotate, causing the threaded rod 12 to drive the lifting plate 18 to move up and down. The lifting plate 18 drives the wheel 19 to move up and down through the connecting plate 20, realizing the lifting of the wheel 19. Compared with traditional devices, this design ensures the stability of the machine during operation, realizes flexible movement. By precisely controlling the rotation speed and direction of the motor 16, the height of the wheel 19 can be smoothly adjusted to ensure that the machine can maintain a stable support state on different terrains or work surfaces. This dynamic adjustment ability effectively prevents the machine from shaking or tilting due to uneven ground or changes in the working load, thus ensuring the continuity and safety of the working process.

[0028] Among them, a pressing block 2 is fixedly installed at the top of the packaging groove 5. A fixing rod 9 is rotatably installed inside the pressing block 2. The fixing rod 9 is rotatably installed outside the pressing block 2. A magnet 8 is fixedly installed at the bottom of the pressing rod 10.

[0029] By setting the magnet 8, when the pressing rod 10 is squeezed by the vacuum compressor 22 and approaches the fixing plate 3, through the suction force of the magnet 8, the packaging bag is firmly fixed on the top of the fixing plate 3, avoiding the deviation of the packaging bag resulting in an inclined seal. The precise positioning and strong adsorption of the magnet 8 ensure the absolute stability of the packaging bag during the sealing process, effectively preventing the packaging bag from shifting due to extrusion, air flow or other external factors. This stability directly improves the accuracy of the seal, reduces problems such as inclined seals and air leakage caused by improper positions of the packaging bag, and improves the overall quality of the packaged products.

[0030] Among them, a limiting block 17 is fixedly sleeved on the outer surface of the top of the sliding rod 13. The limiting block 17 is fixedly installed at the inner top of the lifting groove 11. A belt 15 is fixedly sleeved on the outer surfaces of the two pulleys 14.

[0031] By setting the limiting block 17, when the lifting plate 18 slides up and down on the surface of the sliding rod 13, by setting the limiting block 17, the situation that the lifting plate 18 tilts when moving to the topmost position is avoided. The limiting block 17 serves as a physical barrier, effectively restricting the excessive movement of the lifting plate 18 in the vertical direction, ensuring that it can stop smoothly when reaching the preset height, and preventing the tilting phenomenon caused by inertia or external forces. This stability is crucial for maintaining the balance and normal operation of the entire device.

[0032] Among them, connecting plates 20 are fixedly installed at both ends of the lifting plate 18. The two connecting plates 20 are both slidably installed inside the lifting groove 11. Wheels 19 are fixedly installed at the bottoms of the front, rear, left and right ends of the two connecting plates 20.

[0033] By providing a connecting plate 20, the up-and-down movement of the lifting plate 18 drives the connecting plate 20 to move up and down, causing the connecting plate 20 to drive the wheels 19 to move up and down. When the device needs to be moved, the motor 16 is started, and the wheels 19 contact the ground to achieve movement. When the device needs to work, the motor 16 is started, and the wheels 19 rise into the interior of the body 1 to firmly fix the device.

[0034] Among them, a bottom plate 21 is fixedly installed at the bottom of the body 1, the bottom plate 21 is fixedly installed at the bottom of the sliding rod 13, and a vacuum compressor 22 is rotatably installed at the top of the body 1.

[0035] By providing the bottom plate 21, when the device is working, the bottom plate 21 contacts the ground, enabling the device to operate stably on the ground. By providing the bottom plate 21, the bottom plate 21 fixes the sliding rod 13, allowing the lifting plate 18 to lift and lower stably on the sliding rod 13 and the threaded rod 12.

[0036] Among them, a motor 16 is fixedly installed at the bottom of the pulley 14 located on the back, a motor fixing block 23 is fixedly installed at the bottom of the motor 16, and the motor fixing block 23 is fixedly installed at the top of the lifting groove 11.

[0037] By providing the motor fixing block 23, when the motor 16 operates, due to the setting of the motor fixing block 23, the stable operation of the motor 16 is ensured, enabling the entire lifting mechanism to operate efficiently. The motor fixing block 23 provides a firm and stable installation foundation for the motor 16. When the motor rotates at high speed or bears a large load, the fixing block can effectively prevent the motor from shaking or displacing, ensuring the smoothness and reliability of the motor operation.
