[0001] The utility model relates to the technical field of packaging machines, in particular to a screw packaging machine. Background Art

[0002] The screw packaging machine is a machine that can automatically sort, count, and package screws, nuts and other products with regular shapes. Its functional structure is mainly composed of a hopper, chassis, PLC control system, optical fiber counting system, pneumatic device and other supporting components.

[0003] In the existing device, the screws are cleaned in advance before being sent for packaging to remove dust and dirt on the surface. However, if the installation process is carried out directly after cleaning, it is easy for water stains to adhere to the surface of the screws. Under long-term moisture, the screws are easily corroded and rusted. In addition, the existing device cannot control the feeding rate during the feeding process. Feeding too fast or too slow will affect the processing rate and quality. In addition, the feeding mechanism often cannot control the guide and opening size of the screw material feeding, resulting in a mismatch with the packaging bag size of the packaging mechanism, resulting in packaging failure and the screws detaching from the packaging mechanism.
