The invention provides a folding type
snow and rain prevention device of a sealing-tape
machine. The folding type
snow and rain prevention device is composed of a fixed
pulley, a fixed support, a
steel rope, sliding supports, rainproof covers, a
steel rope locking device and a hinge. The fixed support is fixed to a longitudinal beam of the sealing-tape
machine, the two ends of the
steel rope wound on the fixed
pulley on the lower portion of the fixed support are fixed to side walls of a movable hopper through the steel
rope locking device, at least three sliding supports are arranged on two sides of the movable hopper, lower end chutes of the sliding supports are arranged on the steel
rope, and the rainproof covers cover the sliding supports. The folding type
snow and rain prevention device can be driven to compress on one side and spread on the other side along with parallel moving of the
discharge movable hopper on the sealing-tape
machine, therefore, the full-length working face of the outdoor sealing-tape machine can be always within the range of the rainproof covers, the problem that
material quality is reduced under snowy and
rainy weather is solved, moistures of materials can be stable, normal operation of a
system can be guaranteed, and production halt loss can be avoided.
