Problems solved by technology

[0003] The purpose of the present invention is to provide a pressure-adjustable and visualized calendering and scratching device, which solves the shortcomings of the existing foam scratchers that the pressure cannot be adjusted and cannot be visualized, and records the pressure of products of different specifications during production to effectively control the scratches. The pressure of the bubble device ensures that the cord has no bubbles, and at the same time avoids the quality problems of the cord caused by excessive pressure

Embodiment

[0018] When the calendering linkage production line is started, the solenoid valve (2) operates and passes through the manual valve (3). The manual valve can choose the air path to pass through the pressure regulating valve (5) or the electric proportional valve (4). By adjusting the pressure of the pressure regulating valve or After the pressure of the electric proportional valve, the gas path enters the end of the cylinder (8), and the cylinder stretches out. The cylinder is fixed on the traverse device of the air bubble device through the cylinder mounting bracket (7), and the stabbing wheel (10) is installed on the cylinder rod head of the cylinder (8) through the stabbing wheel bracket (9). The wheel is pressed on the calender roll and slides back and forth through the traverse device, thereby playing the role of pinching air bubbles. When the pressure is found to be too high or too low during the production process, the pressure can be readjusted through a pressure regul...

Abstract

The invention discloses a pressure-adjustable visual calendering bubble scarification device. The device aims to solve the problems that in the field of tire production, a calender bubble puncturing device is unadjustable in pressure and nonvisual. The device can effectively control pressure of a bubble scarification machine and ensure that a curtain cloth has no bubble, and meanwhile avoids the curtain cloth quality problem caused by overlarge pressure. The device is mainly composed of an air cylinder, an air cylinder installation support, a puncturing wheel and a puncturing wheel support, and is combined with a matched gas circuit part so as to achieve corresponding functions.

Description

technical field [0001] The invention belongs to the technical field of tire machinery manufacturing, and in particular relates to a bubble pricking device for a calender. Background technique [0002] Semi-steel radial tire fiber and steel wire dual-purpose cord calendering machine, in the process of calendering the cord, there are often air bubbles in the cord that cannot be removed in time, resulting in thin cords. Sometimes it also happens that the air bubble device makes the cord pierce hole too large to cause thread leakage. Both of these phenomena will affect the tire quality to a certain extent. The air bubble device is generally divided into two parts, one part is the foam cutting device, which plays the role of contacting with the curtain to pierce the air bubbles, and the other part is the transverse movement device, which drives the foam cutting device to move laterally in the width direction of the curtain to avoid missing air bubbles. At present, the pressure ...
