Technical Field

[0001] The utility model belongs to the technical field of sealing machine positioning, in particular to a sealing machine positioning mechanism. Background Art

[0002] A sealing machine is a machine that seals containers containing products. After the product is loaded into the packaging container, in order to keep the product sealed and preserved, maintain product quality, and avoid product loss, the container needs to be sealed. This operation is completed by a sealing machine.

[0003] For example, a Chinese patent with announcement number CN219807040U discloses a positioning mechanism of a sealing machine, including a workbench, a sealing machine body is fixedly connected to the top of the workbench, a conveyor belt is fixedly connected to the top of the workbench, a positioning assembly is provided on the conveyor belt, and the positioning assembly includes a cross plate, a plurality of fixed seats are fixedly connected to the bottom of the cross plate, a plurality of guide rods are symmetrically fixedly connected at the edge of the conveyor belt, and the plurality of fixed seats are movably sleeved on the guide rods respectively, a slide groove is symmetrically provided on the top of the cross plate, a slider is slidably connected to the inside of the slide groove, a threaded rod is rotatably connected to the inside of the slide groove, the threaded rod is movably sleeved on the threaded rod, and the limit plate is fixed to the bottom of the slider; by designing a positioning assembly, the present application can effectively avoid the situation where the overall position of the packaging bag is changed due to the movement of items inside the packaging bag when the packaging bag moves on the top of the conveyor belt, thereby achieving the effect of improving the sealing quality of the packaging bag to a certain extent.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when used, such as: when positioning the packaging bag, this device can only position the entire packaging bag, while the sealing machine seals the bag mouth of the packaging bag. The bag mouth of this device is not limited, resulting in the bag mouth of the packaging bag being offset when it is sealed, thereby affecting the quality of the seal. In addition, after the packaging bag is sealed, this device requires personnel to manually unload the material, which is troublesome and affects work efficiency. In view of this, we propose a positioning mechanism for the sealing machine. Utility Model Content
