Non-woven fabric air cooler

Abstract

The invention discloses a non-woven fabric air cooler, and belongs to the technical field of non-textile machinery. The non-woven fabric air cooler comprises a machine frame, an upper air box lift adjusting mechanism which is arranged on the top portion of the machine frame, an upper air box and a lower air box. A set of air outlet grooves extends out of one side of the upper air box facing towards the lower air box, one end of the upper air box is connected with an external air supply mechanism in a matching mode, the lower air box is arranged on the lower portion of the machine frame, a set of air outlet boxes is formed in one side of the lower air box facing towards the upper air box, air outlet holes are formed in one side surface of each air outlet box facing towards the upper air box, a set of cloth guide rollers is arranged on one side of the lower air box facing towards the upper air box, a corresponding air outlet box is arranged between two adjacent cloth guide rollers, one end of the lower air box is connected with an external air introducing mechanism in the matching mode, the external air introducing mechanism is arranged on the top portion of the machine frame, and a gap reserved between the upper air box and the lower air box is a non-woven fabric via channel. The non-woven fabric air cooler has the advantages of improving cooling effect and cooling efficiency, ensuing even cooling and improving adaptability.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a non-woven air cooler, which is used to cool non-woven fabrics from a heat-setting machine. . Background technique [0002] In the production process of non-woven fabrics, it is necessary to introduce the non-woven fabrics formed by the needle punching machine into the heat setting device (also called hot air oven) for heat setting, so that the low melting point fibers can be melted and transformed into a glass state. The technical information about the heat setting device can be fully interpreted by not limited to US Patent No. US5052197 and Chinese Patent Grant No. CN2286763Y. After the non-woven fabric goes out of the heat setting device, it usually needs to be cooled before winding or cutting and winding, because if the non-woven fabric is rolled without cooling, the non-woven fabric will cause adhesion. [0003] In the prior art, there are roug...

Problems solved by technology

[0003] In the prior art, there are roughly the following methods for cooling or claiming the method of cooling the non-woven fabric from the heat setting device: the one is to use water cooling, and the cooling roller To cool the non-woven fabric passing through the cooling roller, due to the complex structure of the water cooling device and the possibility of leakage, manufacturers of non-woven products do not pay much attention to it; the second is to cool down naturally by slowing down the winding speed. Although the method does not need to rely on a special cooling device such as a water cooling device, the heat setting efficiency is affected because the winding speed is too slow, because there is a common phenomenon of non-woven fabric redundancy between the winding roller and the heat setting machine, and if the heat setting The temperature of the device is appropriately lowered to meet the requirements of extending the setting time of the non-woven fabric, so the production efficiency will be affected; the third is to use a unilateral or single-sided air duct cooling device to cool the non-woven fabric when it passes above the air duct. Compared with the first two methods, the method has certain advantages, that is, it can eliminate the shortcomings of the first two cooling methods, but in the air cooling process, the non-woven fabric usually blows into a floating state, that is, the non-woven fabric occurs. Floating situation, thus affecting the cooling effect
