Problems solved by technology

[0003] However, it is a very skillful task to bend the corners of the aforementioned cement packaging bags out of the aforementioned built-in valve ports. Now the common corner bending methods in bag manufacturing factories are all done by hand, using the cooperation of manual movements and human eye observations. The production efficiency is low, and the production efficiency and quality are also related to the working status of the people. If the working hours are long, the hands will be tired, the eyes will feel tired, and the efficiency and quality will naturally decline, which is greatly affected by human factors, especially The position and shape of the knuckles cannot be unified, and high efficiency and quality stability cannot be guaranteed

Embodiment Construction

[0048] Please refer to Figure 1 to Figure 12 As shown, it has shown the specific structure of a preferred embodiment of the present invention, including a bag body corner automatic corner folding device, including bag body 10, bag opening mechanism 20, pre-opening bag opening mechanism 30, auxiliary opening and closing 40, the first manipulator 50, the opening and closing control mechanism 60, the pressing block 70 and the second manipulator 80. The automatic corner-folding operation of the cement bag body 10 is realized by using the automatic corner-folding device of the bag body in this embodiment.

[0049] Among them, such as figure 1 As shown, the bag mouth pressing mechanism 20 is used to press a proper position on the inner side of the bag mouth of the bag body 10, usually the position where the built-in valve mouth is located. The bag opening mechanism 20 can be an air cylinder device or a hydraulic cylinder device arranged above or below the bag body 10 , and the a...

Abstract

The invention discloses an automatic folding device for a bag corner and a folding method and an auxiliary opening and closing part of the automatic folding device. The device comprises a bag opening pressing mechanism, the auxiliary opening and closing part, a first mechanical arm, an opening and closing control mechanism and a pressing block. The auxiliary opening and closing part is used for turning a bag opening. The first mechanical arm is used for driving the opening and closing part to automatically move or driving a bag and the bag opening pressing mechanism to move automatically. The opening and closing control mechanism is used for controlling the opening and closing part to be automatically opened or closed. The pressing block is used for pressing the bag corner after the bag is opened. The opening and closing part is used as an auxiliary tool for corner folding of the bag opening. Corner folding can be rapidly achieved through opening and closing of the opening and closing part, the folding position and angle are adjustable and controllable, efficiency is high, and quality is stable. Particularly, the auxiliary opening and closing part is used, and then in cooperation with the bag opening pressing mechanism, the mechanical arm, the opening and closing control mechanism and the pressing block, the corner folding can be automatically achieved; a traditional manual operation mode is replaced, in this way, the efficiency is greatly improved, meanwhile, labor is saved, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to the technology in the field of packaging bag body processing, in particular to an automatic corner-folding device for a bag body, a corner-folding method, and an auxiliary opening and closing part. Background technique [0002] Such as Figure 13 Shown is a cement packaging bag commonly used in the market today. The bag body 10 is a cement packaging bag with inner flaps 13 formed on both sides. During the cementing process, the cement ash splashes outward from the bag, and a built-in valve port 12 needs to be folded at a corner of the bag mouth. Then use a conveying pipe to insert into the bag body 10 through the built-in valve port 12, and use the conveying pipe to fill the cement into the bag. Because the opening of the built-in valve port 12 is inside the bag, cement ash produced during the filling process cannot splash out. [0003] However, it is a very skillful task to bend the corners of the aforementioned cement packa...
