Abstract

The invention discloses an extrusion device for a tread. The extrusion device comprises a discharging mechanism containing raw materials as well as a horizontally arranged ejecting mechanism, whereinthe lower end of the discharging mechanism is connected with the ejecting mechanism; the ejecting mechanism comprises an ejecting casing, an outlet is formed in the ejecting casing, a left side mold is connected at the outlet, the upper end of the left side mold is glidingly connected with a pattern part, a horizontal first wedge is connected onto the pattern part, a second wedge cooperating withthe first wedge is arranged on the first wedge, a traction piece is connected between the first wedge and the second wedge, a chute located beside the ejecting casing is connected onto the second wedge and glidingly connected with a slider, the slider is connected with a gear and located in the position, deviated from the circle center, of the gear, a rack is arranged below the gear, and a bent part bent upwards is arranged at the end, close to the outlet, of the rack. The tread formed with the technical scheme is matched better with a required tread in length, the tread is not needed to be cut any more, a few processing steps are needed, time is saved, and work efficiency is high.

Description

technical field [0001] The invention relates to the technical field of tread production equipment, in particular to an extrusion device for tread. Background technique [0002] Tires are widely used in the transportation industry. With the improvement of people's living standards, more and more people buy vehicles, and the demand for tires is gradually increasing. In the production process of the tire, a layer of tread needs to be attached to the surface of the tire. The molding of the tire tread is completed on the extrusion device. The extrusion device extrudes the raw material forming the tread into a tread. The shape and size need to meet the process requirements, and the shape and size of the tread are controlled by the left mold installed on the machine head. [0003] In order to increase the coefficient of friction, the tread of the tire usually requires some textures, but the basic tread extruded by the extrusion device on the market is basically smooth and has no t...
