After the flexible packaging bag is evenly flattened, the thickness of the flexible packaging bag is accurately measured and determined by observing the positions of the pressing plate and the ruler, after the thickness of the flexible packaging bag is measured, production equipment is adjusted according to production requirements, the required standard thickness of the flexible packaging bag is achieved, all operation standards can be standardized, and production efficiency is improved.

Description

Technical Field

[0001] The utility model relates to the field of measuring equipment, in particular to a thickness measuring device for a soft packaging bag. Background Art

[0002] In order to prevent food from being squeezed or deteriorated during transportation and storage, some foods are packaged in air-containing soft bags, that is, in addition to a certain amount of target packaging materials (powders, liquids, gels, small solid particles, expanded solids), some air or inert gas is also filled into the soft bag packaging bags of food. However, in addition to the target packaging materials that can be quantitatively loaded into the soft bag packaging bags, the filling of air or inert gas is controlled by the operator, which ultimately leads to the thickness of the soft bag after packaging also varying from person to person. Different people adjust the thickness of the soft bag packaged by the operator, which may cause the soft bag packaging bags to be unable to be loaded into the soft bag box in the future, and then stop the line or rework, which is wasteful and inefficient. Therefore, it is necessary to quickly measure the thickness of the soft bag packaging bags after packaging during production, so that the thickness of the soft bag packaging bags can be adjusted and controlled in time to keep a basically uniform size range during production.

[0004] The thickness measuring device of the flexible packaging bag described in the utility model comprises a bottom plate for placing the flexible packaging bag, the bottom plate is vertically provided with a guide rod, a pressing plate which passes through the guide rod and can move up and down relative to the bottom plate is arranged above the bottom plate, a sliding bearing which passes through the guide rod and can move up and down along the guide rod is also arranged above the pressing plate, the sliding bearing is connected to the pressing plate, and a component for measuring the distance between the bottom plate and the pressing plate is provided.

[0005] Preferably, a flange is provided at one end of the sliding bearing connected to the pressure plate, a through hole is provided on the flange for screws to pass through, and a threaded hole matching the through hole in the flange is provided on the pressure plate, so that the sliding bearing and the pressure plate can be detachably connected by screws.

[0006] Preferably, there are two or more guide rods, and there are also two or more sliding bearings matched with the guide rods.

[0007] Preferably, the pressing plate is also provided with a handle for conveniently lifting the pressing plate.

[0008] Preferably, cup feet with adjustable height and level are installed at the four corners of the bottom of the base plate.

After the pressure plate is lifted higher than the thickness of the soft packaging bag to be measured, the soft packaging bag to be measured is placed on the bottom plate, and then the pressure plate is pressed back. After the soft packaging bag is evenly flattened, the thickness of the soft packaging bag is accurately measured and determined by observing the position of the pressure plate and the ruler. After measuring the thickness of the soft packaging bag, the production equipment can be adjusted according to production needs to achieve the required standard thickness of the soft packaging bag, so that all operating standards can be standardized and production efficiency can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 The figure is a schematic diagram of the structure of a thickness measuring device for a flexible packaging bag. DETAILED DESCRIPTION

[0013] like Figure 1 As shown, a thickness measuring device for a flexible packaging bag comprises a base plate 1 for placing the flexible packaging bag, a guide rod 2 is vertically arranged on the base plate, a pressing plate 3 which passes through the guide rod and can move up and down relative to the base plate is arranged above the base plate, a sliding bearing 4 which passes through the guide rod and can move up and down along the guide rod is also arranged above the pressing plate, the sliding bearing is connected to the pressing plate, and a component 5 for measuring the distance between the base plate and the pressing plate, the component for measuring the distance between the base plate and the pressing plate is a ruler, the ruler is installed on the side of the base plate, and further, the ruler is welded and fixed to one side of the base plate. The thickness measuring device for the soft packaging bag can make the pressing plate move up and down smoothly relative to the guide rod under the guiding sliding action of the sliding bearing, thereby preventing the pressing plate from being unable to move up and down due to the force between the pressing plate and the guide rod due to the excessive area and weight of the pressing plate. After the pressing plate is lifted higher than the thickness of the soft packaging bag to be measured, the soft packaging bag to be measured is placed on the bottom plate, and then the pressing plate is pressed back.
