[0002] The riveting machine is a new type of riveting equipment developed based on the principle of cold rolling. It refers to mechanical equipment that can rivet objects together with rivets. The equipment has a compact structure, stable performance, and convenient and safe operation. The riveting machine mainly relies on rotation and pressure to complete the assembly. It is mainly used in occasions where riveting is required, such as the riveting processing of decorative items.

[0003] The riveting machine described in publication number CN206500568U usually uses a conventional vibration plate for feeding. During processing, the rivets are placed in the vibration plate, and then the rivets are transported side by side to the designated position through the vibration of the vibration plate. A riveting head is arranged above the designated position, and the riveting head absorbs the rivets and transfers them to the top of the riveting seat. The decoration is placed on the riveting seat, and the riveting head screws the rivets to the decoration by hot pressing, thereby completing the riveting operation between the rivet and the decoration.

[0004] The above-mentioned prior art solutions have the following defects: the rivets are vibrated and transported to the specified position by the vibration plate, which easily causes the rivets to be placed unevenly, thereby affecting the riveting processing efficiency of the decoration, so there is still room for improvement.

A covering member is provided on the outer sides of the conveyor belt and the supporting track. The covering member covers the conveyor belt and the supporting track. A avoidance hole is opened on the top of the covering member. The avoidance hole is located above the limiting hole. The suction mechanism is located on one side of the feeding mechanism. The suction mechanism is used to absorb and transfer the rivets to the riveting mechanism. The riveting mechanism is located on one side of the suction mechanism.
