Description

Technical Field

[0001] The utility model relates to the technical field of bagging, in particular to a device for expanding and compacting material bags. Background Art

[0002] During the loading process, an opening device is used to open the material bag. However, some loose materials are not compacted, which will result in a small amount of material loaded. For example, the publication (announcement) number is CN219428414U, a rice husk bagging machine for a rice production workshop. Although a pressure plate is provided in the structure to compact the material loaded in the material bag and increase the bagging amount, the filling mechanism and the pressure plate mechanism of the bagging machine are operated separately and cannot be compacted while loading. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present scheme provides a material bag expanding and compacting device, which is achieved by the following specific technical means: it includes a base and multiple groups of vertical frames arranged on the periphery of the base, each group of the vertical frames is provided with a movable seat slidingly, and a ring seat is located between the multiple groups of vertical frames, and a support arm is movably connected between the ring seat and each group of the movable seats, and at the same time, a pressure plate is installed on the bottom side of the ring seat, and a clamping mechanism is arranged on the ring seat, and the clamping mechanism is used to clamp the discharge pipe head of the feeder inserted into the ring seat, and a hole is opened on the pressure plate facing the discharge pipe head, and a bag expanding mechanism is arranged on the base below the ring seat, and the bag expanding mechanism is used to expand the material bag mouth.

[0004] Preferred technical solution 1: The bag-supporting mechanism is composed of a bag-supporting assembly arranged on each set of vertical frames, and the bag-supporting assembly includes a telescopic rod 1 installed at the bottom end of the vertical frame and a bag-supporting member arranged on the inner telescopic end of the telescopic rod 1.

[0005] Optimal technical solution two: A vertical screw is rotatably provided on each group of the vertical frames, and the movable seat is sleeved on the vertical screw through a threaded hole. The synchronous rotation of multiple groups of vertical screws can drive the ring seat to move up and down, thereby completing the compaction action.

[0006] Preferred technical solution three: A motor is provided on the vertical frame, and the output shaft of the motor is fixedly connected to the vertical screw rod.

[0007] Preferred technical solution four: the top surface of the pressing plate is an upward convex arc surface, so that the material splashed onto the top surface of the pressing plate slides down along the arc surface.

[0008] Preferred technical solution five: an elastic member is connected between the pressure plate and the bottom wall of the ring seat.

[0009] The above structure enables this solution to have the following beneficial effects:

[0010] 1. During the bagging process, the bag opening is opened by the bag-supporting mechanism, and then the material is injected through the discharge pipe head clamped and fixed by the ring seat. During the injection process, the lateral position of the discharge pipe head is adjusted by intermittent rotation of each set of vertical screw rods to improve the uniform distribution of the material in the material bag;

[0011] 2. The downward and horizontal movement functions of the ring seat can drive the pressing plate to compact the material during the filling process, thereby increasing the bagging capacity of the material bag;

[0012] 3. The convex arc structure of the pressing plate prevents the material from being retained on the top surface of the pressing plate. BRIEF DESCRIPTION OF THE DRAWINGS
