Description

Technical Field

[0001] The utility model relates to the technical field of powder packaging, in particular to a placing device for packaging bags used for packaging. Background Art

[0002] Powders such as calcium carbonate are sub-packed in 25-kilogram packaging bags. During the sub-packaging process, problems often occur such as the packaging bags not being filled fully or the packaging bags being deformed. To avoid such problems, push cylinders are often arranged on both sides of the packaging bags, and the push cylinders are used to push the packaging bags to shake the packaging bags, so that the powder can be fully filled into the packaging bags. However, this method is likely to cause the powder to spill. Secondly, during the filling process, problems such as powder spilling often occur due to insufficient opening of the bag mouth of the packaging bag. Content of the Utility Model

[0003] The utility model provides a placing device for packaging bags used for packaging to solve the deficiencies of the above-mentioned prior art, solve the problems of insufficient opening of the bag mouth of the packaging bag and insufficient filling of the powder, and has strong practicability.

[0004] In order to achieve the purpose of the utility model, the following technologies are proposed:

[0005] A placing device for packaging bags used for packaging includes a chassis. A pair of support plates are installed on the chassis. Guide rails are installed at the upper ends of the support plates. End plates are installed at the outer ends of the guide rails. Hydraulic cylinders are installed on the end plates. A movable seat is arranged at the movable end of the hydraulic cylinder. A movable ring is arranged at the inner end of the movable seat. Outer extension plates are arranged on the outer circumference of the movable ring. Multiple pairs of connecting rods are arranged on the outer extension plates. A placing plate is arranged at the lower ends of the connecting rods. The hydraulic cylinder can drive the movable ring to reciprocate along the length direction of the guide rail. During the movement, the chassis can be shaken through the hydraulic cylinder, and the powder can be fully filled into the packaging bag through the shaking. The chassis plays a supporting role for the packaging bag, and the connecting rods can limit and restrain the packaging bag to prevent the packaging bag from tipping over during the filling process.

[0006] Furthermore, a downward-pulling hydraulic cylinder is installed on the outer extension plate. A movable block is arranged at the movable end of the downward-pulling hydraulic cylinder. A connecting plate in a ring structure is arranged between the movable blocks. Multiple acting wheels are rotatably arranged on the connecting plate. Multiple guide rods penetrate through the movable blocks, and the lower ends of the guide rods are arranged on the outer extension plate. Multiple spring pins penetrate through the outer circumference of the movable ring. Springs are sleeved on the inner ends of the spring pins. An outer movable plate is arranged at the outer ends of the springs. An inner pressing plate is arranged on the outer movable plate. An inclined surface is opened at the upper end of the outer wall of the inner pressing plate. The outer circumference of the acting wheel is tangent to the inclined surface. A pressing plate is arranged on the upper end inner wall of the inner pressing plate. The pressing plate can clamp the bag mouth of the packaging bag through its inner wall when the movable block moves. First, it ensures that the bag mouth of the packaging bag is fully opened. Second, it can prevent tipping over during filling.

[0007] Furthermore, in order to enhance the opening effect of the bag mouth of the packaging bag, an anti-slip rubber pad is provided on the inner wall of the pressing plate.

[0008] Furthermore, in order to further enhance the pressing effect on the packaging bag, a plurality of anti-slip protrusions are provided on the inner wall of the pressing plate.

[0009] The advantages of the above technical solution are as follows:

[0010] The utility model can completely open the bag mouth of the packaging bag, thereby avoiding the scattering of powder during the feeding process, and during the filling process, the shaking can ensure the filling degree of the powder. BRIEF DESCRIPTION OF THE DRAWINGS
