Description

Technical Field

[0001] This utility model relates to a vacuum packaging machine, specifically a vacuum packaging machine for meat products, and belongs to the field of food packaging technology. Background Technology

[0002] Vacuum packaging machines can automatically extract air from packaging bags and seal them after reaching a predetermined vacuum level. They can also be filled with nitrogen or other mixed gases before sealing. Vacuum packaging machines are commonly used in the food industry because vacuum packaging helps food resist oxidation and thus achieves long-term preservation.

[0003] In the packaging process of meat products, the items to be packaged are placed in packaging bags and then vacuum-sealed to complete the packaging. During vacuum packaging, due to the different shapes and sizes of meat products, the packaging bags placed inside the workbench are not only prone to tilting, causing the seals on the packaging bags to tilt, but also prone to causing the liquid inside the packaging bags to leak out. Moreover, currently, multiple packaging bags are usually placed at the same time before their seals are locked and secured, so the packaging bags are also prone to displacement and tipping over during the placement process. Utility Model Content

[0004] The purpose of this invention is to provide a meat product vacuum packaging machine to solve the above problems. This machine can vacuum package meat products of different shapes and sizes, and can also quickly position the meat product packaging bags.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a meat product vacuum packaging machine includes a machine body, a worktable installed at the top of the machine body, support rods rotatably connected to both ends of the worktable, a cover plate rotatably connected to the top of the support rods, a support structure installed inside the worktable, the support structure including a placement groove, the worktable having a placement groove, a support plate slidably connected inside the worktable, the support plate having a groove, an adjustment plate fixedly connected to the top of the support plate, the adjustment plate and the worktable being slidably connected, an adjustment screw rotatably connected inside the worktable, the adjustment screw and the adjustment plate being threadedly connected, a base fixedly connected inside the worktable, a buffer rod slidably connected to the top of the base, a spring fixedly connected between the buffer rod and the base, connecting rods fixedly connected to both ends of the base, and a positioning shaft rotatably connected between the two connecting rods.

[0006] Preferably, the support plates are arranged in a parallel and symmetrical manner, and the grooves are arranged in a linear distribution.

[0007] Preferably, one side of the top of the base has an inclined structure, and the base has multiple components arranged in a parallel and symmetrical relationship.

[0008] Preferably, the buffer rod has an overall convex shape, and the top of the buffer rod has an arc-shaped structure.

[0009] Preferably, a limiting structure is installed on the base, the limiting structure includes a guide plate, the guide plate is fixedly connected to the side end of the base, and the guide plate is generally arc-shaped.

[0010] Preferably, a limiting ring is fixedly connected to the positioning shaft, and the limiting ring abuts against the guide plate.

[0011] Preferably, the limiting ring has an overall circular structure and is made of rubber.

[0012] Preferably, a fixing column is fixedly connected inside the base, and the fixing column and the buffer rod are slidably connected.

[0013] Preferably, a slide rod is fixedly connected to the top of the workbench, and the slide rod and the adjusting plate are slidably connected.

[0014] The beneficial effects of this utility model are as follows: The packaging bag is placed in the placement slot of the workbench and supported by two support plates inside the workbench. At the same time, the meat product is locked in place by the groove. Therefore, it can not only prevent the packaging bag from tipping over due to irregular shape of the meat product, thus affecting the vacuum packaging quality of the meat product, but also prevent the liquid inside the meat product from flowing out of the packaging bag. By rotating the adjusting screw, the height of the adjusting plate and the support plate can be adjusted, thereby supporting meat products of different sizes. The positioning shaft rotating on the connecting rod can position the sealing end of the packaging bag placed on the base and the buffer rod, preventing the packaging bag from sliding and tilting during operation, thus affecting the sealing. Then, the cover plate is pressed down, and the buffer rod sliding in the base and the spring installed at the bottom of the buffer rod can cushion the packaging bag placed on the buffer plate, preventing damage to the packaging bag during vacuum packaging.
