Abstract

The invention provides a compound extrusion unit for producing tubeless bicycles and a mouth device thereof. According to flow direction of a sizing material, the mouth device comprises a performed mouth board, a mouth board and a mouth box, which are sequentially connected; and the mouth board is embedded in the mouth box. The performed mouth board has an integral structure; the mouth board comprises an upper mouth board and a lower mouth board, which are matched with each other; the extrusion unit comprises an extrusion system and a temperature-control system, which are connected with each other; the extrusion system comprises three compound heads and three extrusion machines which are connected with the three compound heads respectively; and three extrusion machines are arranged pickaback, and the mouth device in the three compound heads is the mouth device. The mouth device can avoid streaming and burning of the sizing material in the process of inner compounding and guarantee stable extrusion of the products; and meanwhile, the volume of the device is small and maintenance of equipment is convenient because the extrusion machines are assigned pickaback; and mold components are locked by utilizing a lock, so that locking effect is good and shaping effect of tires is also good.

Description

technical field [0001] The invention relates to a bicycle tire manufacturing technology, in particular to a composite extruding unit and die-forming device for producing a tubeless bicycle tire. Background technique [0002] Traditional bicycle tires are divided into outer tires and inner tubes, which are usually manufactured separately by two sets of equipment. Tubeless bicycle tires are more and more widely used because of their good air tightness and strong wear resistance. However, at present, there are few extruders that can form tubeless bicycle tires at one time. Japan's Nakata Machinery has developed a compound extrusion unit for tubeless bicycle tires. However, because the arrangement of the extruders is L-shaped, extrusion The reducer and the motor on the output machine need to be connected through the side flange, which makes the maintenance of the equipment complicated. When the reducer is repaired, the motor must be disassembled first, thus increasing the maint...
