Sizing machine capable of keeping even weft density of gauze

Abstract

The invention relates to a sizing machine capable of keeping even weft density of gauze. The sizing machine comprises a pair of carry-over pinch rolls, a sizing roll and a pair of squeezing rolls. The carry-over pinch rolls are arranged transversely and parallelly, the sizing roll is arranged below a link of the two carry-over pinch rolls, and the squeezing rolls are arranged on two sides of the link of the two carry-over pinch rolls respectively. The sizing machine is characterized in that a clamping device is further arranged below the link of the two carry-over pinch rolls and comprises a belt-type conveyer, two sets of gauze clamps which are arranged on a conveying belt of the belt-type conveyer and are respectively arrayed along the conveying direction, and a gauze drive device, and the two sets of gauze clamps are arranged outside tow ends of the sizing roll respectively. The sizing machine clamps the edge of gauze located in a sizing area by the gauze clamps synchronously moving along with the gauze, and accordingly tension of wefts at the part is kept, the wefts are prevented from irregular motion under action of traction force, distance among the wefts is even and quality of gauze is increased. An optical sensor can be arranged outside the gauze clamps at two ends of the belt-type conveyer to control tensioning and clamping of the gauze clamps and to be better matched with conveying rate of gauze, and accordingly automation degree is high and operation efficiency is improved.

Description

technical field [0001] The invention relates to a sizing machine in the field of textile machinery, in particular to a gauze sizing machine. Background technique [0002] As a kind of cloth with sparse warp and weft yarns, gauze has a wide range of uses. The sizing process refers to the process of applying size to warp yarns to improve their weavability. The weavability of gauze is very important. Unsized single yarn fibers do not cohere firmly with each other, and the surface has more hairiness, making it difficult to weave. At present, the commonly used sizing machine uses the traction roller to pull the gauze along the warp direction. The warp of the gauze is always tightened, while the weft is loose. Especially when sizing, the yarn is wetted by the size, and the loose weft is easy to produce irregular The movement will cause the weft yarn to be skewed, the distance between the weft yarns will be uneven, and even large holes will be generated, which will seriously affe...
