Embodiment 1

[0069] Hereinafter, the detailed structure of each part of this belt cushion film manufacturing device will be described through Embodiment 1.

[0070] Described extruder comprises machine barrel 11, single-screw structure 12 first reduction box 13 and machine head 17, as Figure 2-4 As shown, the rubber raw material enters from the rubber raw material inlet 8, and is extruded through the barrel 11 and the single screw 12. The upper structure of the single screw 12 has a saw-toothed helix. The head of the single screw structure 12 is connected with the first reduction box by splines. The first reduction box 13 has a first circular shaft, a second circular shaft, and a third circular shaft. Fourth circular axis. The first gear is arranged on the first circular shaft, the second gear and the third gear are arranged on the second circular shaft, the fourth gear and the fifth gear are arranged on the third circular shaft, and the sixth gear is arranged on the fourth circular shaf...

Embodiment 2

[0084] Further, due to the stirring action of the high-speed rotating single screw 12 and the internal pins of the barrel 11 on the rubber material, the temperature of the rubber material will increase, thereby increasing the possibility of air bubbles in the rubber sheet made of the rubber material. In view of this, an embodiment of the present invention provides a manufacturing device for a belt buffer film, which also includes:

[0085] Cooling device 3, the cooling device 3 is used to press the calendering device 2 to cool the rubber sheet of the first thickness to the first temperature, the cooling device 3 is as Figure 12 As shown, six cooling drums 311-316 and six second motors 321-326 are included. The cooling drums 311-316 are made of stainless steel, and the outer surface in contact with the rubber sheet is made of stainless steel to prevent impurities from being mixed into the rubber sheet. There are interlayers in the cooling drums 311-316, and cooling circuits f...

Embodiment 3

[0088] Further, in order to avoid the problem of uneven thickness in the buffer film manufacturing process, in view of this, a temperature control system, an alarm system, a temperature control method, and an alarm method are provided. Specifically, the first pressure and / or the first temperature are determined based on the temperature and composition of the rubber raw material.

[0089] The manufacturing device of the belt buffer film is equipped with a control system, and the control system includes a controller, an interactive interface, a readable storage medium, a bus and a display.

[0090] The temperature control system includes a first temperature control system and a second temperature control system, the first temperature control system is used to control the temperature of the extrusion device, and the second temperature control system is used to control the temperature of the calendering device , The temperature control system includes a heating loop and a cooling ...

Abstract

The invention discloses a belted layer buffer film manufacturing device, a control system and a control method. A rubber raw material is extruded by utilizing first pressure and / or first temperature, the rubber raw material is pressed by utilizing an arc-shaped calendering space of an extrusion device and a calendering device, a rubber sheet pressed by the calendering device is stored by utilizing a temporary storage device, and the cut buffer rubber sheet is adhered to a belted layer, so that the problems that in the prior art, a buffer rubber sheet is stored through a curling storage device, and consequently the buffer rubber sheet is cooled, shrunk and hardened are solved, and the adhesion degree of the buffer film is improved.

Description

technical field [0001] The invention relates to the field of tire manufacturing, in particular to a belt buffer film manufacturing device, a control system and a control method. Background technique [0002] The belt layer of the tire is made by covering the tire with multiple cords around the tire. As an important part of the tire structure, it mainly protects the carcass, enhances the tread strength, and carries and transmits stress. , in the actual use process, due to the load, driving force, braking force and lateral force exerted by the tire, a certain part of the tire will be subjected to a large force. In the actual use process, it is manifested as delamination of the first and second belt layers of the tire, which seriously affects the driving safety of the car. [0003] In the prior art, the thickness of the buffer film in the tire manufacturing process varies. If the thickness of the buffer film is thin, the effect of balancing the stress cannot be achieved; if th...
