Problems solved by technology
[0002] In the production of antibiotics, oral liquids, blood products and other products, it is necessary to use aluminum-plastic covers for sealing. The ordinary riveting machine is composed of a feeding mechanism, a riveting mechanism, a transmission mechanism, a heating element, and a frame. This equipment is due to the aluminum The positioning between the cover, the plastic cover and the riveting body is inaccurate, and the aluminum and plastic covers cannot be tightly fitted during riveting, resulting in incorrect riveting points, damage to the aluminum cover, and the riveting and flanging part of the plastic cover cannot completely press the aluminum cover. Lead to low yield and low efficiency
In addition, the aluminum cover and plastic cover are pre-synthesized separately, and then heat riveted. The structure is complex and the yield is not high.

Embodiment Construction
[0007] A positioning riveting device for an aluminum-plastic cover, comprising a guide rod 1 and a riveting rod 2, a riveting head 4 at the front of the riveting rod 2, a riveting spring 3 arranged between the guide rod 1 and the riveting rod 2, and a riveting spring 3 A pre-riveting sleeve 5 is arranged outside the closing head 4, a pre-riveting spring 6 is arranged on the pre-riveting sleeve 5, and a limit rod 7 is arranged inside the pre-riveting sleeve 5. The front end 5 of the pre-riveting sleeve is provided with a guide section 8 .
[0008] When the device is used, the riveting rod 2 goes down, and the pre-riveting sleeve 5 first contacts the aluminum cover. Since the head of the pre-riveting sleeve 5 outside the riveting head 4 has a guide section 8, the aluminum cover is centered by the guide section 8. . The riveting rod 2 continues to descend, and the pre-riveting sleeve 5 makes the aluminum cover and the plastic cover tightly fit under the action of the pre-rivetin...

The invention provides an aluminium-plastic cap locating riveting device, belonging to parts of an aluminium-plastic cap riveting machine. The device is mainly characterized by adding pre-riveting sleeves, springs, a limiting rod and other parts to an original riveting head, wherein guide sections are arranged at the heads of the pre-riveting sleeves. The device has the following beneficial effects that: the aluminium cap can be centered and prepressing and riveting can be smoothly implemented in the same riveting process, thus effectively solving the problems of riveting point disalignment caused by inaccurate locating and untight fit of the aluminium cap and the plastic cap in the original equipment and effectively improving the production efficiency and the yield.
