Rubber extruding and spraying device

Abstract

The invention relates to a rubber extruding and spraying device and solves the problems that water flow impact easily impacts shallow pits on a rubber strip and the water flow difficultly covers the whole width of the rubber strip of the rubber strip spraying device in the prior art. The device comprises a conveying trough for conveying rubber strips, wherein a water supply pipe is arranged at the upper part of the conveying trough; a plurality of nozzles are uniformly arranged on the water supply pipe along the rubber strip conveying direction; the device is characterized in that each nozzle comprises a nozzle body; a vertical water channel is formed in each nozzle body; the upper end of each water channel is connected with the water supply pipe; a lower end opening of each water channel is a horn-shaped opening extended upwards; an umbrella-shaped adjusting block capable of adjusting up and down is arranged on the lower side of the lower end opening of each water channel; the top surface of each umbrella-shaped adjusting block is a conical surface; axes of the conical surfaces are in flush with the axes of the water channels. The rubber extruding and spraying device is large in water curtain coverage range; the water uniformly drops; the impact on the rubber strips is reduced; the shallow pits are avoided; with cooperation of coarse adjusting threads and fine adjusting threads, the positions of the umbrella-shaped adjusting blocks can be adjusted, so that the water yield and the water curtain shape can be adjusted.

Description

technical field [0001] The invention belongs to the field of rubber molding equipment and relates to a rubber extrusion spraying device. Background technique [0002] The production of rubber strips is generally formed by a rubber extruder. The rubber raw material is in a fluid state in the extruder. Therefore, the temperature of the rubber strip just extruded from the rubber extruder is high, and the shape is soft and easy to deform. Therefore, a spray device is generally installed on the back side of the rubber extruder to spray and cool the extruded rubber strip to harden the rubber strip. The traditional rubber strip spraying device generally adopts a water spray pipe that is in the same direction as the rubber strip. The water spray pipe is aligned with the rubber strip to set a drip hole, and the spray liquid is dripped onto the rubber strip. Since the rubber strip just extruded is relatively soft, the droplets directly dripping from the spray liquid are relatively la...
