Embodiment Construction

[0017] Hereinafter, an embodiment of the present invention will be described based on the drawings.

[0018] exist figure 1 The side view of the manufacturing apparatus (it may just describe as "manufacturing apparatus" hereafter) 1 of the rubber belt of this embodiment is shown in . Such as figure 1 As shown, the manufacturing apparatus 1 is provided with a rubber extruder 2 for continuously discharging rubber, and a pair of upper and lower calender rolls 3, 3 for rolling the rubber discharged from the rubber extruder 2 to form a rubber belt G.

[0019] The manufacturing apparatus 1 of this embodiment is suitably used for the raw tire manufacturing apparatus M which molds the rubber belt G used for manufacturing a tire, for example. The green tire manufacturing apparatus M is provided with, for example, a pick-up roll M1 that picks up the rubber belt G from the calender roll 3, a storage unit M2 that temporarily stores the rubber belt G on the downstream side of the pick-up...

Abstract

The rubber belt manufacturing apparatus provided by the present invention can suppress damages such as cracks on the outer layer of calender rolls made of ceramics, and can continuously roll rubber belts for a long period of time. The manufacturing device (1) of the rubber belt is equipped with: a rubber extruder (2), which has a discharge port (2a) for continuously discharging rubber; The rubber is rolled to form a rubber belt (G). Each calender roll (3) includes: a roll main body (7) driven to rotate, and a cylindrical outer layer (8) concentrically arranged outside the roll main body (7) and rolling rubber with an outer peripheral surface (8S). ). The outer layer (8) consists of ceramics. A gap (P) is provided between the outer layer (8) and the roller body (7). An O-ring (10) for integrally rotating the outer layer (8) and the roller body (7) is inserted into the gap (P).

Description

technical field [0001] The present invention relates to a rubber belt manufacturing apparatus having a pair of upper and lower calender rolls for rolling rubber to form a rubber belt. Background technique [0002] Conventionally, in order to manufacture an unvulcanized rubber belt, a manufacturing apparatus has been proposed that includes a rubber extruder that continuously discharges rubber, and a pair of upper and lower calender rolls that roll the discharged rubber (for example, refer to the following: Patent Document 1). Each of the calender rolls includes a rotationally driven roll main body and a cylindrical outer layer fixed outside the roll body. The roller main body is formed of metal. On the other hand, the outer layer is formed of ceramics. Such an outer layer has the advantage that unvulcanized rubber hardly adheres to the outer layer made of metal. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2011-194737 [0004] When rolling the rubber dischar...
