Description

Technical Field

[0001] The utility model relates to the field of valve pocket cutting devices, and more specifically, to a valve pocket cutting device. Background Art

[0002] Valve pockets, commonly known as bottom-pasted bags, are internationally popular packaging bags. They are fed from the top or bottom valve openings and use special filling equipment. After filling the materials, they are formed into cubes, neatly stacked, and beautiful, belonging to environmentally friendly bags. Valve pockets are mainly used for packaging powdered or granular solid materials such as edible powders, chemical powders, fertilizers, synthetic materials, explosives, grains, salts, minerals, etc., as well as flexible items. They are especially suitable for export enterprises and can improve the packaging grade of products.

[0003] Currently, the manufacturing of valve pockets usually has achieved fully automated production. Only manual sorting and packing are required after production. Due to the production of the equipment, after processing, they are usually scattered and stacked at the end of the production line. Workers need to collect many valve pockets from the conveyor belt and then pack them. Some valve pockets are closely attached to the conveyor belt, making it cumbersome to collect them manually and difficult to take away the valve pockets at the bottom. Therefore, a stacking device that can facilitate the packing of valve pockets is needed. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a device that can facilitate the packing of valve pockets.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: A valve pocket cutting device includes a valve pocket machine frame. A first conveyor belt is arranged on the valve pocket machine frame. A cutting machine and a stacking part are arranged on the first conveyor belt. The feature is that: The stacking part is located at the end of the conveyor belt. The stacking part includes a second conveyor belt and stacking blocks. The second conveyor belt is located at the end of the first conveyor belt and multiple stacking blocks are fixed on the second conveyor belt. A stacking surface is formed on the stacking blocks, and a stacking gap is formed between the stacking surface and the stacking blocks.

[0006] By adopting the above technical solution, a stacking surface and a stacking gap are formed, enabling valve pockets to be stacked within the stacking surface, facilitating packing and sorting at a designated place. When there are too many stacks, they can fall into the stacking gap as a whole for convenient packing.

[0007] The present utility model is further arranged as: One end of the stacking block is provided with a pressing block. The stacking surface is formed by the pressing block. The pressing block is rotatably arranged on the stacking block. A first torsion spring connecting the pressing block is arranged on the stacking block. A fixing part connecting and fixing the other end of the pressing block is arranged on the stacking block.

[0008] By adopting the above technical solution, a rotating pressing block is provided. After a certain number of valve bags are stacked on the stacking surface and are brought to the packing station by the rotation of the second conveyor belt, by pressing the pressing block, the valve bag can rotate together with the pressing block, so that the valve bag falls into the stacking gap, and at the same time, a certain degree of arrangement can be carried out during the rotation, which is convenient for subsequent packing and arrangement.

[0009] The present utility model is further arranged as follows: a limiting block located at the end of the first conveyor belt is provided on the second conveyor belt, and an inclined surface is provided on the limiting block. When the stacking block moves to the limiting block, the inclined surface restricts the valve bag from separating from the stacking surface.

[0010] By adopting the above technical solution, the limiting block and the pressing block cooperate to restrict the valve opening from falling from the first conveyor belt to the second conveyor belt, avoiding situations such as dropping.

[0011] The present utility model is further arranged as follows: a locking member for fixing the stacking block is provided on the second conveyor belt. The locking member includes a fixing rod and a clamping block. The fixing rod is fixed on the second conveyor belt and a plurality of them are connected. The clamping block rotates on the fixing rod. The clamping block is L-shaped, and a first limiting groove is formed on the stacking block for cooperation therewith.

[0012] The present utility model is further arranged as follows: the fixing member includes a limiting ball and a limiting spring. The limiting spring connects the limiting ball. A limiting groove for cooperation therewith is provided on the stacking block. The limiting ball slides in the limiting groove, and a fixing limiting groove is recessed on the pressing block.

[0013] By adopting the above technical solution, the pressing block is clamped, and at the same time, the limiting ball is provided, so that when there are too many stacked valve bags, the pressing block can rotate, which is convenient for packing.

[0014] The present utility model is further arranged as follows: guiding inclined surfaces are provided at both ends of the stacking block.

[0015] By adopting the above technical solution, it is prevented that the valve bag separates.

[0016] The present utility model is further arranged as follows: a buckling hole is provided on the stacking surface.

[0017] By adopting the above technical solution, when the pressing block rotates, it is convenient to take the valve bag from the buckling hole. Description of the Drawings
