Steam chamber cloth feeding port dripping-proof device

Abstract

The invention discloses a drop-proof device which can effectively prevent condensed water drop or working solution drop from dropping on a steamer fabric entering opening on the fabric, comprising a drop-proof plate arranged on the fabric entering opening, wherein, the width of the drop-proof plate is no less than that of the fabric. The drop-proof device is characterized in that the inner side edge of the drop-proof plate is passed through an upper lateral plate of the sealing cavity plate of the fabric entering opening and the sealing surface of a roller surface between a fabric entering and guiding roller and the upper lateral plate inside the steamer body. The drop-proof device with the structure is mainly applied to the steamer which has the fabric entering opening provided with a sealing device.

Description

technical field [0001] The invention relates to an anti-drip device for a cloth inlet of a steam box, in particular to an anti-drip device which can be used in conjunction with a sealing device for the cloth inlet. Background technique [0002] In the printing and dyeing machinery industry, the steam box is used to steam the fabric soaked in the working fluid. The steaming box is equipped with a cloth inlet—that is, the cloth inlet channel for the fabric to enter the box from outside the box. Run, and finally lead out the steam box from the cloth outlet. The anti-drip device is usually installed in the cloth inlet. The anti-drip device that is often used at present is the anti-drip plate installed in the cloth inlet. The drip plate is heated; the anti-drip plate is located above the fabric, its width is usually larger than the width of the fabric, its length is slightly longer than the length of the cloth inlet, and its inner edge slightly extends into the inner side of th...

[0003] The applicant submitted an invention patent with the application number 200620075905.6 to the Patent Office of the China Intellectual Property Office on July 19, 2006, disclosing a sealing device for the cloth inlet of the steam box, wherein the upper side plate of the sealing chamber There is a roller surface seal between the cloth feeding guide roller and the steam box body. Due to the existence of the roller surface seal, the working fluid stained on the cloth feeding guide roller will be on the roller surface seal during work. As the work progresses, the working fluid accumulated at the seal of the roll surface will inevitably drip down. Since the seal surface of the roll surface is relatively far away from the side wall of the box, the traditional anti-drip plate It will not play a blocking role, and the dripping working fluid will undoubtedly drip on the fabric below it, thus forming a secondary fabric.
