Embodiment Construction

[0024] Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0025] Such as figure 1 As shown, the rubber member manufacturing apparatus 1 of the present embodiment supplies and winds a belt-shaped rubber belt G2 made of unvulcanized rubber on the outside of a rotatable substantially cylindrical wound body 2 to manufacture an air-filled body. A device for ring-shaped rubber parts for tires. The rubber member includes at least an inner liner, a tread rubber, a side rubber, and the like, although not particularly limited.

[0026] The manufacturing device 1 of the present embodiment has a rubber extruder 3 , a calender head 4 , and a rubber applicator 5 .

[0027] figure 2 A partial sectional view of the rubber extruder 3 is shown. The rubber extruder 3 includes a rubber extruder body 6 and a gear pump 7 connected to a discharge port 6 d of the rubber extruder body 6 .

[0028] The main body 6 of the rubber extruder includes: a su...

Abstract

The invention provides a manufacturing device of a rubber part capable of manufacturing ring-shaped rubber part by supplying band-shaped rubber strips made of unvulcanized rubber and coiling the rubber strips on the outer side of the coiled body. The device (1) used for manufacturing the ring-shaped rubber parts can be used to supply the rubber strips (G2) and coil the rubber strips on the outer side of the coiled body (2). The device is characterized in that a rubber extrusion device (3) comprises a rubber extrusion machine body (6) provided with a spiral shaft, a gear pump(7) is connected with a discharging opening of the rubber extrusion machine body (6); a rolling head (4) is used to roll the rubber extruded by the rubber extrusion device (3) to the predetermined cross section shape to acquire the rubber strips (G2); and a rubber application device (5) can be used to receive the rubber strips (G2) from the rolling head (4), and is used to supply the rubber strips to the coiled body (2) for the bonding, and the rubber application device (5) can receive the rubber strips (G2) from the rolling head (4) without passing through a storage device.

Description

technical field [0001] The present invention relates to a manufacturing apparatus for rubber parts capable of manufacturing endless rubber parts by supplying and winding a belt-shaped rubber tape made of unvulcanized rubber around the outer side of a wound body. Background technique [0002] A tape winding method is known as a method of forming a rubber member used in a green tire (raw tire) of a pneumatic tire. In the tape winding method, such as Figure 8 As shown, the unvulcanized rubber belt b formed in a belt shape continuously extruded from the rubber extrusion device a is continuously stacked and wound on the cylindrical wound body d using the rubber applicator c, Thereby, an annular rubber component (for example, tread rubber, sidewall rubber, etc.) is formed. Such a tape winding method is highly versatile because it can obtain various cross-sectional shapes by changing the winding pitch of the rubber tape. In addition, since the tape winding method does not requir...
