Description
Technical field
The invention belongs to the Winding Machine technical field, be specifically related to a kind of rolling-up mechanism of dewaxing glass fiber cloth.
Background technology
Be called the glass fibre silastic fabric by glass fabric as the one or both sides surface coating of base material or the resulting cloth of calendering silastic-layer, be called for short glass fibre silicone fabric, if in silaatic, add fire retardant matter such as magnesium hydroxide, aluminium hydroxide and/or antimony oxide or the like, be referred to as glass fiber flame retardant silica gel cloth so.This cloth can be applicable to Aeronautics and Astronautics, navigation, oil, medication chemistry production, traffic, generating, HVAC, Architectural Equipment and electric apparatus equipment or the like, is mainly used in flexible sealing and connects.
The first road step of glass fibre silicone fabric production recited above is the glass fiber cloth dewaxing that needs to come from commercially available channel, and so-called dewaxing is that the paraffin wax type surface treating agent that glass fabric is contained melts and removes, and becomes exposed inorganic glass fiber.Prior art is with glass fabric to be dewaxed tying-in high temperature dewaxing furnace in a continuous manner.Specifically: glass fabric is emitted (on yardage roll, withdrawing from) by the unreeling machine that is positioned at dewaxing furnace one side, behind dewaxing furnace by the rolling-up mechanism rolling that is positioned at the dewaxing furnace opposite side.
The rolling-up mechanism of above-mentioned dewaxing glass fiber cloth is arranged on the winding roller pivot on the frame usually, and be in transmission connection with power drive, drive the winding roller rotation by power drive, when winding roller batches to required amount, it is taken off from frame, change another winding roller and continue to batch.The rolling-up mechanism of this version is widely used in textile printing and dyeing industry.But there is following problem: the one, troublesome poeration; operating personnel's labour intensity is big; because; because winding roller directly is connected with power drive; therefore after the silica gel cloth on the winding roller increases gradually and reaches required amount (normally controlling the amount of every volume silica gel cloth) in the mode of metering metering; under stopped status; promptly under the out-of-work state of power drive; make the roll shaft releasing of winding roller and being connected of power drive; winding roller is taken the glass fiber flame retardant silica gel cloth that is wound on the winding roller to be taken away; change empty i.e. replacing winding roller to be rolled up, and it is connected with power drive.Therefore, at every turn the winding roller that will completely roll up get from and winding roller that will be to be rolled up change, will the process that be in transmission connection and implement to be in transmission connection take place to remove with power drive all, so, can increase online operating personnel's labour intensity undoubtedly; The 2nd, efficient is batched in influence, because winding roller and power drive direct connection, it is tediously long therefore to change institute's time-consuming, and efficient is batched in influence; The 3rd, reeling quality is difficult to guarantee, occurs the gyro phenomenon easily, and so-called gyro phenomenon is meant that the silica gel cloth on the winding roller produces the olive effect, for follow-up processing causes difficulty.
Therefore, be necessary the structure of the rolling-up mechanism of the dewaxing glass fiber cloth in the prior art is improved, for this reason, the applicant retrieves, but in disclosed patent and non-patent literature, there is no all technology contents that the aforementioned disadvantages eliminated is arranged, carry out positive exploration and repay examination through the applicant, find a way to resolve the problem finally, technical scheme described below produces under this background.
