Description

Technical Field

[0001] This utility model relates to the technical field of vacuum packaging equipment for health products, and in particular to a vacuum packaging machine for health products. Background Technology

[0002] With increasing health awareness, the demand for health supplements has surged. Vacuum packaging, as a key technology for ensuring the shelf life of health supplements, places ever-increasing demands on the precision and efficiency of packaging machines. Traditional packaging machines are difficult to adapt to different specifications of health supplements, and problems such as inadequate sealing and insufficient vacuum are prone to occur during the packaging process, affecting product quality. Existing vacuum packaging machines for health products have significant drawbacks. Traditional equipment typically consists of a simple housing and a fixed clamping structure with a fixed clamping distance, making it unsuitable for packaging bags of different sizes. For example, small bags are easily unstable when clamped, while large bags cannot be placed. The lack of a flattening component leads to wrinkles in the packaging film, resulting in inadequate sealing, and uneven heating by the heating strip affects sealing quality. Vacuum extraction and clamping are not synchronized, easily causing insufficient vacuum due to bottle movement. The lifting structure has low adjustment precision, making it impossible to adjust the position according to bottle height, resulting in cumbersome operation. Ultimately, this leads to poor adaptability and inconvenience in operation. Therefore, this application designs a vacuum packaging machine for health products to solve the above problems.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 4 This utility model discloses a vacuum packaging machine for health products, comprising a base 2, a housing 1 mounted on the upper end of the base 2, and a door 3 hinged to one end of the housing 1.

The base 2 provides support, the housing 1 forms a sealed space, the lifting block 12 drives the mounting plate 9 to rise and fall, the sliding plates 4 and the clamping assembly fix the health products, and the flattening assembly processes the packaging film, realizing the entire vacuum packaging process. A first motor 6 is installed on the side end of the mounting plate 9, and the sliding groove rotates... Equipped with two bidirectional lead screws, which are coaxially fixed to the motor shaft of the first motor 6, and four sliding plates 4 are threadedly connected to the two bidirectional lead screws respectively, with the four sliding plates 4 symmetrically distributed in pairs; the first motor 6 drives the bidirectional lead screws to rotate, causing the sliding plates 4 to slide in opposite directions, adjusting the clamping distance, improving the convenience of feeding and unloading materials, and enhancing clamping flexibility; the base 2 is equipped with a vacuum pump, and the lower end of the housing 1 has a connecting port 7 that connects to the vacuum pump pipeline; heating strips 15 are installed on the lower inner side of each sliding plate 4, and sliding grooves are opened on the upper inner side of each sliding plate 4; a second motor 8 is installed on the side of each sliding plate 4; the vacuum pump extracts air from the housing through the connecting port 7, the heating strips 15 heat the sealing, and the second motor 8 provides power to the flattening component, ensuring the vacuum environment and sealing effect.

[0015] In this utility model, a cavity is provided in the middle of the inner side of the sliding plate 4. The clamping assembly consists of a clamping block 11 and a spring. The clamping block 11 is slidably installed inside the cavity. Multiple grooves for vacuuming are provided on the side end of the clamping block 11. The spring is installed between the clamping block 11 and the cavity. The spring pushes the clamping block 11 to clamp the health product. The grooves facilitate air circulation to ensure vacuum, prevent excessive clamping from damaging the packaging, and improve clamping stability. The lifting block 12 is provided with a worm gear and a worm. The inner wall of the worm gear is threaded to the first lead screw 5. A third motor 10 for driving the worm is provided on the side end of the lifting block 12. The teeth of the worm gear mesh with the helical teeth of the worm. The three motors 10 drive the worm gear to rotate the worm wheel, causing the lifting block 12 to rise and fall along the first lead screw 5, precisely adjusting the height of the mounting plate 9 to accommodate health products of different heights; the sliding groove has a pressure roller 14 slidably installed inside, and the upper end of the pressure roller 14 is rotatably mounted with a second lead screw 13. The outer wall of the second lead screw 13 is threaded with a slider, and the lower end of the slider is fixedly connected to the upper end of the pressure roller 14. The motor shaft of the second motor 8 is coaxially fixedly connected to the second lead screw 13; the second motor 8 drives the second lead screw 13 to rotate, causing the pressure roller 14 to move along the sliding groove, flattening the wrinkles of the packaging film, and improving the flatness and sealing performance of the seal. The first motor 6, the second motor 8 and the third motor 10 are all YD series variable speed motors.

[0016] Working Principle: When using this invention, first connect the power supply to the device. The operator opens the door 3 hinged to one end of the housing 1 and places the health product to be packaged between the four sliding plates 4 in the sliding groove on the side of the mounting plate 9. Then, according to the height of the health product packaging bag seal, the operator starts the third motor 10 installed on the side of the lifting block 12 through the wireless terminal controller. The third motor 10 drives the worm gear inside the lifting block 12 to rotate. Because the spiral teeth of the worm gear mesh with the teeth of the worm wheel, and the inner wall of the worm wheel is threadedly connected to the first lead screw 5 installed inside the housing 1, the rotation of the worm wheel will drive the lifting block 12 to rise and fall along the first lead screw 5, thereby driving the mounting plate 9 connected to the side of the lifting block 12 to the appropriate position. The height is adjusted to meet the packaging requirements of health products of different heights; then, the first motor 6 installed on the side of the mounting plate 9 is started. Since the motor shaft of the first motor 6 is coaxially fixed to two bidirectional lead screws rotatably installed inside the sliding groove, and the four sliding plates 4 are respectively threaded to the two bidirectional lead screws and are symmetrically distributed in pairs, when the first motor 6 drives the bidirectional lead screws to rotate, it will drive the four sliding plates 4 to slide in opposite directions along the sliding groove. At this time, the clamping block 11 in the middle cavity inside the sliding plate 4 initially clamps the health product under the push of the spring. At the same time, the multiple grooves opened on the side of the clamping block 11 can reserve air circulation space, avoiding damage to the packaging by clamping too tightly while ensuring the subsequent vacuum extraction effect; during this process, the side of the sliding plate 4 is started simultaneously. The second motor 8 has its motor shaft coaxially fixed to the second lead screw 13 in the sliding groove at the upper end of the inner side of the sliding plate 4. The slider threaded to the outer wall of the second lead screw 13 is fixed to the upper end of the pressure roller 14, which is slidably disposed in the sliding groove. Therefore, when the second motor 8 drives the second lead screw 13 to rotate, it will drive the pressure roller 14 to move along the sliding groove, thereby flattening the wrinkles on the surface of the health product packaging bag and improving the flatness and sealing of the subsequent sealing. After the health product clamping and packaging film flattening operation is completed, the operator closes the box door 3 and starts the vacuum pump inside the base 2 through the wireless terminal controller. The vacuum pump draws air from inside the box 1 through the connecting port 7 at the lower end of the box 1. The air passes through the connecting port 7 and the side of the clamping block 11 in sequence. The groove at the end enters the vacuum pump, ultimately creating a vacuum environment inside the health product packaging bag. Once the vacuum level reaches the preset requirement, the first motor 6 is restarted, causing the four sliding plates 4 to continue moving in opposite directions until the heating strip 15 installed on the lower inner side of the sliding plate 4 is completely in contact with the sealing area of ​​the health product packaging bag. Then, the heating strip 15 is energized and heats the sealing area of ​​the packaging bag, completing the sealing operation. After sealing, the vacuum pump stops working, the operator opens the door 3, controls the first motor 6 to reverse, causing the four sliding plates 4 to slide back to their original positions along the sliding groove. At this point, the packaged health product can be taken out. Finally, the power to the first motor 6, the second motor 8, and the third motor 10 is turned off, and the entire vacuum packaging process for the health product is completed.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
