Description

Technical Field

[0001] The utility model relates to the technical field of product packaging, in particular to a continuous vacuum packaging device. Background Art

[0002] Vacuum packaging is a technology that extends the shelf life and preservation quality of food and other products by removing the air inside the package and sealing it. First, a vacuum pump is used to extract the air inside the packaging bag, reducing the oxygen content, thereby inhibiting the growth of bacteria and mold. After vacuuming, the packaging bag is immediately heat-sealed or mechanically sealed to prevent external air from entering again. This serves to extend the shelf life of the video, reduce oxidation and microbial growth, while reducing the packaging volume for easier storage and transportation, and reducing the impact of moisture and external contaminants to keep the product dry.

[0003] Currently, the existing vacuum packaging devices are provided with upper and lower templates, and exhaust holes connected to the vacuum pump are opened on the upper and lower templates. After the upper and lower templates are closed, vacuum packaging treatment is carried out. However, due to certain gaps existing after the upper and lower templates are closed, a vacuum state cannot be achieved inside the template cavity, affecting the vacuuming process, thus ensuring the quality of product packaging and also affecting the packaging efficiency, with certain defects. Summary of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a continuous vacuum packaging device, which has the advantages of being able to improve the packaging quality and efficiency of products, etc., and solves the problems that when directly closing the upper and lower templates at the present stage, there are gaps, resulting in insufficient vacuuming treatment, and low product packaging quality and packaging efficiency.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solution: A continuous vacuum packaging device includes a lower mold cavity assembly and an upper mold cavity assembly. The lower mold cavity assembly includes a lower mold cavity outer shell, a lower template is installed on the lower mold cavity outer shell, and a lower heating plate is installed at one end of the lower template. The lower mold cavity outer shell provides a protective effect for the lower template. At the same time, the top surface of the lower mold cavity outer shell is inclined, and the top surface of the lower template is flush with the top surface of the lower mold cavity outer shell, so as to facilitate the picking and sending of the bag body to be packaged.

[0008] The upper die cavity assembly includes an upper die cavity housing mounted on the lower die cavity housing. A support beam is installed inside the upper die cavity housing, and the bottom end of the support beam is fixed to the lower die cavity housing. At the same time, an upper template is installed on the support beam. An upper heating plate is installed at one end of the upper template, and the upper heating plate corresponds to the lower heating plate. The upper die cavity housing is used to provide protection for the upper template, and the upper template and the lower template are horizontally opposite. When the lower template moves backward into the upper die cavity housing, it can correspond to the upper template, so that the upper and lower heating plates are aligned. When the upper template moves downward and closes with the lower template, the effect of bag mouth encapsulation treatment is achieved.

[0009] When the continuous vacuum packaging device is performing the packaging work, the bag to be packaged is placed in the lower template, and the position of the bag mouth to be packaged is attached to the lower heating plate. By controlling the operation of the driving wheel, the lower template drives the bag into the bottom of the upper die cavity housing until the lower template is aligned with the upper template. At this time, the upper and lower heating plates correspond to each other. By controlling the operation of the electric telescopic rod, its output end drives the upper template to descend and close with the lower template. At the same time, the upper heating plate and the lower heating plate clamp the bag mouth. At this time, under the state of being connected and operating with the vacuum pump connected through the air extraction interface, the air in the bag is evacuated. After multiple vacuum evacuation treatments, the air in the bag is fully evacuated, and then the two heating plates are controlled to operate to heat-seal the bag mouth.

[0010] As a further improvement of the above solution, an electric hydraulic rod is fixed inside the lower die cavity housing, and the output end corresponds to the side of the lower template.

[0011] Through the above technical solution, two electric hydraulic rods are distributed at the tail end inside the lower die cavity housing, and the two electric hydraulic rods operate synchronously. According to the length of the output end of the hydraulic rod extending, the distance that the lower template moves is controlled, so as to ensure that the lower template can be accurately aligned with the upper template.

[0012] As a further improvement of the above solution, a stable slide rail is fixed on the inner wall of the lower die cavity housing. At the same time, a protective side plate is fixed on the side of the lower template, and a driving wheel is installed on the side of the protective side plate. The driving wheel is movably connected to the stable slide rail.

[0013] Through the above technical solution, protective side plates are installed on both sides of the lower template, and driving wheels are installed at both ends of the protective side plates. The driving wheels operate synchronously, and a storage battery for providing kinetic energy to the driving wheels is installed. By rotating the driving wheels forward or backward on the stable slide rail, the lower template is driven to move backward into the bottom of the upper die cavity housing or forward to leak out.

[0014] As a further improvement of the above solution, a retaining side plate is fixed to the bottom of the support beam, an electric telescopic rod is fixed to the bottom of the retaining side plate, a positioning side plate is fixed to the side of the upper template, an installation joint is fixed to the side of the positioning side plate, and the output end of the electric telescopic rod is fixed to the installation joint.

[0015] Through the above technical solution, retaining side plates are installed at both ends of the bottom of the support beam, two electric telescopic rods are equidistantly distributed and installed on the retaining side plates, and the electric telescopic rods operate synchronously, so that their output ends drive the upper template to move up and down, realizing the function of closing with the lower template.

[0016] As a further improvement of the above solution, auxiliary side plates are fixed to the sides of the lower template and the upper template and correspond to each other.

[0017] Through the above technical solution, the design of the auxiliary side plates can ensure that the bag body is accurately placed into the cavity of the template, avoiding the leakage of the edge of the bag body.

[0018] As a further improvement of the above solution, exhaust holes are provided on both the lower template and the upper template. At the same time, both the upper and lower templates are connected with air extraction interfaces, and the air extraction interfaces are connected to the exhaust holes through pipelines.

[0019] Through the above technical solution, the tail end of the air extraction interface is connected to a vacuum pump. Through the operation of the pump body, air is extracted outward, so that the gas in the template cavity is extracted from the exhaust holes, making the inside of the bag body in a vacuum state.

[0020] As a further improvement of the above solution, an installation interface is provided at one end of the outer shell of the lower die cavity, and a limit baffle is detachably installed in the installation interface, and the limit baffle fits against the side of the lower template.

[0021] Through the above technical solution, the limit baffle is used to prevent the lower template from detaching from the outer shell at the installation interface during movement. After removing the limit baffle, the lower template can be taken out for maintenance work.

[0022] As a further improvement of the above solution, a rubber soft pad is fixed to the output end of the electro-hydraulic rod, and the rubber soft pad fits against the side of the lower template.

[0023] Through the above technical solution, when the lower template moves into the upper die cavity shell, it contacts the rubber soft pad at the tail end, thus realizing the buffering function.

[0026] 2. In the continuous vacuum packaging device, the lower template is driven by a driving wheel to enter the shell body and close with the upper template to achieve a sealing effect, thereby further improving the safety of use. At the same time, through the design of the inclined movement of the lower template, it not only facilitates the conveying operation of the product, but also can prevent the product in the packaging bag from leaking out, further improving the packaging effect.
