Rubber powder feeding device

Abstract

The invention provides a rubber powder feeding device, comprising a material holding cylinder, a feeding cylinder, a motor, a dust extraction device, and a material height detection device arranged in the material holding cylinder. The cylinder wall of the feeding cylinder is in a hollow structure, and comprises an inner wall and an outer wall on the outer side of the inner wall. A drying device is arranged between the inner wall and the outer wall. The inner side of the outer wall is provided with a thermal insulation layer. The upper end of the feeding cylinder is provided with a blanking elbow, and the lower end extends into the material holding cylinder. The outlet of the blanking elbow is provided with an adjusting plate. The motor drives a feeding shaft which is arranged in the feeding cylinder to rotate. The dust extraction device is arranged on the top end out of the outlet of the blanking elbow. The device is uniform in feeding, and easy in control, and is stable and reliable. The material height detection device can respectively give out alarm sound when feed powders in the material holding cylinder is not sufficient or excessive, and prompts operating personnel. The dust extraction device greatly reduces air pollution and reduces dust loss, and accurate matching of feed powders is easy to realize.

[0002] In the production of rubber products, the rubber powder feeder is an indispensable production equipment. In the past, workers generally poured the powder into the hopper of the rubber product molding equipment manually. Due to the high temperature of the molding equipment , there are potential safety hazards, especially large-scale molding equipment needs to add a large amount of powder, if the entire process is operated manually, the efficiency will be low

Others use mechanical transmission, which is open, scattered in structure, large in size, pollutes the air in the production environment, and is not safe for people; if pneumatic suction or blowing is used, the noise is large, the power consumption is high, and the system and equipment are complicated. It is inconvenient to install and maintain. The shortage and fullness of the material in the hopper are all observed by human eyes, which increases the labor intensity of the operator and is not conducive to production automation.

At the same time, in the prior art, the rubber powder is easy to be damp and agglomerated during storage or production, which affects the proportion of the powder and directly affects the quality of the rubber product.
