The above is an overview of the shapes of the components of the fully automatic bag making machine which can be used as a laminating woven bag for the bottom of the invention; and then, the actions of the present invention and the expected effects can be stated as follows: The present invention starts from the discharge device 30 to the molding device 60, and the outer surface of the cloth 300 is directed downward, and the coating device 50 is The outer surface of the cloth 300 is coated with the non-slip material, and the outer surface of the cloth 300 needs to face upward. Therefore, before the cloth 300 enters the coating device 50, the cloth 300 needs to be turned over.

Referring to FIG. 9, the coating device 50 rolls the cloth 300 by the roller 512, and the cloth 300 is retracted to the movable roller 514 via the lower portion of the frame 511, so that the outer surface of the cloth 300 can be turned upwards. When the user controls the movable roller 514 to move closer to the fixing and cooling roller 513, since the surface of the fixing and cooling roller 513 is exposed to the anti-slip material by the anti-slip blanking die 532, the cloth 300 is in contact with the fixing and cooling roller 513. At the same time, the outer surface of the fabric 300 can be smoothly coated with a non-slip material. Then, the cloth 300 is rewound from the upper portion of the frame 511 to the rear machine, and the outer surface of the cloth 300 is turned face down again for the rear mechanical function to operate smoothly.

Referring to FIG. 10, if the present invention is to make a paper cylinder bag 900, the outer surface of the cloth 300 does not need to be coated with a non-slip material. When the cloth 300 enters the coating device 50, the user can choose to control the non-slip blanking die 532. The anti-slip material is stopped from being sprayed, and the movable roller 514 is moved away from the fixing and cooling roller 513, so that the outer surface of the cloth 300 does not come into contact with the fixing and cooling roller 513, so that the present invention is equally applicable to the production of the paper cylinder bag 900.

In summary, the automatic bag making machine which can be used as a laminating woven bag for wrapping the bottom of the bag is mainly for solving the defect of the production efficiency of the conventional bag making machine, and the main technical means of the invention is to let the cloth be placed. The device 30, the printing device 40, the coating device 50, the molding device 60, the buffer device 70, the cutting device 80, the steering device 90, the sewing device 100, and the bottom device 200 are connected to a production line for consistent operation. Visible final finished product, providing plastic The flat cloth 300 of the rubber or paper material, when the cloth 300 is a plastic material subjected to a coating treatment, the coating device 50 can apply a non-slip material to the outer surface of the cloth 300. When the cloth 300 is made of paper, the cloth 300 The coating device 50 can choose not to perform the coating operation on the cloth 300. Thus, the present invention can be applied to the production of two different cylindrical bags 800 (900) of plastic or paper, and the application range is quite wide. And most importantly, the present invention allows the cloth 300 to sequentially perform the operations of placing, printing, coating, forming, cutting, bottoming, and bottoming through the above apparatus, and finally completing the production of the cylindrical bag 800 having the bottom structure. (900) Finished product, the entire operation process is consistent operation and fully automated mechanical production, in addition to greatly improving the production efficiency of the finished product, and without spending too much manpower, can effectively save labor costs.
