Please refer to the eighth to twelfth figures for the operation mode of the embodiment of the present invention.

As shown in the eighth figure, in use, the opening of the bag body (60) to be packaged is first opened, and the bag mouth is sleeved on the bag portion of the guiding member (31) of the bag body holding device (30). (312), the machine is started to press the two crimping members (32) of the bag holding device (30) to clamp the bag body (60), and then the control valve of the storage tank (43) (431) Opening, the particles or powder material in the hopper (43) will naturally fall into the measuring hopper (42) by gravity, and the electronic scale (41) detects the measuring hopper at any time (42) The weight of the material in the medium, and the value is transmitted to the electronic control device. When the value is close to the set value, for example, the set value is 50 kg, the control valve is automatically closed when it is close to 49 kg or nearly 49.5 kg (431). And feeding by the dosing device (44), by the constant speed rotation of the screw (442) of the dosing device (44), the material in the hopper (43) enters the tube through the feeding tube (444) (441), and is driven by the screw (442) at a constant speed, and discharged from the discharge port of the pipe body (441), falls into the measuring hopper (42), and automatically closes when the set value is reached. The automatic feeding device (40).

As shown in the ninth figure, when the material in the measuring hopper (42) reaches the set value, the end cover (421) of the measuring hopper (42) is automatically opened, and the material is automatically dropped by the gravity to the guiding member (31). The guide portion (311) is dropped into the bag body (60) through the guide through hole (310) to perform a loading operation.

As shown in the tenth figure, after the filling is completed, the empty (oil) cylinder (34) of the bag holding device (30) rises, and the bag body (60) is lifted up to make the bag body (60) The bottom of the conveyor device (20) is closed.

As shown in the eleventh figure, when the ascent reaches the position and then descends, the bottom of the bag (60) is again placed on the conveying device (20). The purpose of this action is to shake the material to make it compact and compact, which is convenient for the next seam opening operation.

As shown in the twelfth figure, the crimping member (32) of the bag holding device (30) is retracted. When the bag body (60) is loosened, the conveying device (20) is activated, and the bag body (60) is sent to the position of the bag machine (50) to perform the sewing operation of the bag mouth.

The invention has the advantages of simple structure, relatively low cost, and no space occupation, and is very suitable for small and medium-sized enterprises, especially for a small number of users, and can be operated by one person, that is, the packaging operation can be completed more quickly than usual.

The bag-holding portion of the guiding member of the automatic bag-carrying device of the invention is specially designed, and the inclined surface is used to form a portion for the opening of the bag body, and then the crimping member is used to clamp the open end of the bag body, and the structure is convenient for field work. The operation of the personnel, at the same time, can firmly clamp the mouth of the bag, and the bag body can be smoothly taken out after the filling is completed, thereby achieving the requirement of quick operation.
