[0002] Vacuum sealing is a common packaging method in the modern packaging industry, widely used in food, pharmaceuticals, and electronic products. While traditional vacuum sealing machines can achieve basic sealing functions, they have some shortcomings in practical use. As market demands for packaging quality and production efficiency continue to increase, higher requirements are being placed on the performance and functionality of vacuum sealing machines.

[0003] In traditional vacuum sealing packaging machines, packaged goods are prone to folding or tilting during transport, preventing them from entering the vacuum chamber flat. This not only affects the appearance quality of the seal but can also lead to sealing failure, reducing the sealing and reliability of the packaging, thus impacting product quality and shelf life. Therefore, ensuring that packaged goods remain flat during transport is a crucial technical problem that needs to be solved. This device was invented to address these issues. Utility Model Content

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] See attached document Figures 1-5 This embodiment of a semi-automatic vacuum sealing and packaging machine includes a frame 1, a conveying mechanism 2, a packaging guide device 3, a vacuum chamber 4, and a sealing mechanism 5.

[0030] See attached document Figures 1-3The frame 1 includes a base plate 101 and movable columns 102. Casters 104 are fixedly installed at the four corners of the bottom of the base plate 101. The movable columns 102 include a fixed frame 1021 and a movable upright 1022. The fixed frame 1021 is fixedly installed on one side of the top of the base plate 101, and a reinforcing frame is also fixedly installed between the base plate 101 and the fixed frame 1021. A one-way screw 1023 is rotatably installed inside the fixed frame 1021. The one-way screw 1023 is vertically arranged. The rod 1022 is threadedly connected to the one-way screw 1023, and the width of the movable upright 1022 is equal to the width inside the fixed frame 1021, thereby limiting the movable upright 1022 and enabling the movable upright 1022 to move longitudinally along the fixed frame 1021 during the rotation of the one-way screw 1023. A support platform 103 is fixedly installed on the top of the movable upright 1022, and a reinforcing frame 2 is fixedly installed between the movable upright 1022 and the support platform 103.

[0031] A No. 1 motor 1024 is installed on the fixed frame 1021. A bevel gear set 1025 is provided between the output shaft of the No. 1 motor 1024 and the one-way screw 1023. When in use, the No. 1 motor 1024 is turned on. Under the connection of the bevel gear set 1025, the output shaft of the No. 1 motor 1024 drives the one-way screw 1023 to rotate, thereby realizing the vertical movement of the movable upright 1022 and the support platform 103. This facilitates adjustment according to the height of different packaging materials and improves the applicability of the equipment.

[0032] See attached document Figure 1 The conveying mechanism 2 is located on the top of the support platform 103. The conveying mechanism 2 described in this embodiment uses a common conveyor belt, so its working principle and specific structure will not be described in this embodiment.

[0033] See attached document Figure 1 and Figure 5 The packaging guide device 3 includes two upright plates 301 fixedly installed on the top of the support platform 103, and the two upright plates 301 are respectively set on both sides of the conveying mechanism 2. A double-rotating screw 302 is rotatably installed between the two upright plates 301, and a guide rod 303 is fixedly installed between the two upright plates 301. A second motor 304 is installed on one of the upright plates 301. The output shaft of the second motor 304 is connected to the double-rotating screw 302. When in use, the second motor 304 is turned on, and the output shaft of the second motor 304 drives the double-rotating screw 302 to rotate. Both sides of the double-rotating screw 302 are threadedly connected to connecting plates 305, and the guide rod 303 passes through the connecting plates 305 on both sides to limit the connection plates 305, so that the connecting plates 305 on both sides can move towards or away from each other during the rotation of the double-rotating screw 302.

[0034] A support frame 306 is fixedly installed at the bottom of the connecting plate 305. Multiple limiting rollers 307 are rotatably installed on the support frame 306 at equal intervals. The limiting rollers 307 on both sides move synchronously with the connecting plates 305 on both sides. The multiple limiting rollers 307 on both sides are used to guide the packaged goods into the vacuum chamber 4 to ensure the flatness of the packaged goods when entering the vacuum chamber 4 and to avoid sealing failure due to folding of the packaged goods.

[0035] See attached document Figure 1 and Figure 4 Vacuum chamber 4 is mounted on support platform 103, and sealing component is located inside vacuum chamber 4. When packaged goods enter vacuum chamber 4 under the action of packaged goods guide device 3, sealing component starts to operate and seals the packaged goods. Vacuum chamber 4 includes an inverted U-shaped frame 401, with a pipe 402 connected to the top of frame 401. Pipe 402 is connected to an external vacuum pump (not shown in the figure). Blind curtains 403 are provided at the inlet and outlet of frame 401 to ensure the vacuum effect inside frame 401. The sealing component is fixedly installed in cylinder 501 at the top of the inside of frame 401. A heat sealing strip 502 is connected to the end of the piston rod of cylinder 501. Heating element (such as heating wire) is provided inside heat sealing strip 502. Heating is achieved by electric current to bring heat sealing strip 502 to a sufficient temperature. Once the packaged goods enter the vacuum chamber 4, the conveying mechanism 2 stops, the shielding curtain 403 closes, and the vacuum pump evacuates the vacuum chamber 4 through the pipe 402 to ensure that the vacuum chamber 4 reaches the set vacuum level. The control cylinder 501 operates, and the piston rod of the cylinder 501 drives the heat sealing strip 502 towards the packaged goods, so that the heat sealing strip 502 fits tightly against the packaged goods. At this time, the heating element is energized and heats up, melting the sealing part of the packaged goods. Under the pressure applied by the cylinder 501, the molten sealing part of the packaged goods sticks together, completing the sealing. After the sealing is completed, the piston rod of the cylinder 501 retracts, the heat sealing strip 502 returns to the initial position, and the heating element is de-energized and cooled.

[0036] In this embodiment, the technical solution firstly adjusts the height of the support platform 103 according to the height of the packaged goods. This is achieved by activating motor 1024, which in turn drives the unidirectional screw 1023 via bevel gear set 1025. This causes the movable upright 1022 to move longitudinally along the fixed frame 1021, thus accommodating packages of different heights. The packaged goods are then conveyed to the packaged goods guide device 3 via conveyor mechanism 2 (conveyor belt). Motor 304 in the packaged goods guide device 3 drives the double-rotating screw 302, causing the connecting plates 305 on both sides to move the limiting rollers 307 in opposite directions, adjusting the position of the limiting rollers 307. The conveyor mechanism 2 is positioned to guide the packaged goods smoothly into the vacuum chamber 4. After entering the vacuum chamber 4, the conveyor mechanism 2 stops, the shielding curtain 403 closes, and the vacuum pump evacuates the vacuum chamber 4 through the pipe 402 to achieve the set vacuum level. Then, the cylinder 501 in the vacuum chamber 4 operates, and the piston rod drives the heat sealing strip 502 to move towards the packaged goods. The heating element inside the heat sealing strip 502 is energized and heated, causing the sealing part of the packaged goods to melt. Under the pressure of the cylinder 501, the melted sealing part is bonded together, completing the sealing. After the sealing is completed, the piston rod of the cylinder 501 retracts, the heat sealing strip 502 returns to its initial position, the heating element is de-energized and cooled, and the entire packaging process is completed.

[0037] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
