Open-width washing unit

Abstract

The utility model discloses an open-width washing unit which comprises a washing tank, a plurality of upper cloth guide rollers and a plurality of lower cloth guide rollers are installed in the washing tank, and the upper cloth guide rollers and the lower cloth guide rollers are arranged in the washing tank in an up-down staggered mode. Each upper cloth guide roller is tangent to two adjacent lower cloth guide rollers below the upper cloth guide roller, each lower cloth guide roller is a driving roller, and each upper cloth guide roller is a driven roller; at least one upper cloth guide roller comprises a hollow outer roller, the outer roller is a net roller, and the interior of the outer roller is communicated with a water supply system through a rotary connector and a water pipe. According to the structure of the upper cloth guide roller, in-roller spraying can be achieved, spraying liquid acts on the fabric through meshes of the outer roller, the effect that water penetrates through the cloth is achieved, and the washing efficiency is improved.

Description

Technical Field

[0001] The utility model relates to the field of dyeing and finishing equipment, in particular to an open-width washing unit. Background Art

[0002] In the dyeing and finishing of textiles, in order to remove decomposition products, impurities, floating colors and other residual chemicals in scouring, dyeing, printing and some finishing processes, a washing machine must be used for thorough cleaning. Traditional ordinary compact washing machines usually include several flat washing tanks, with partitions set between adjacent flat washing tanks. Each flat washing tank is equipped with two rows of upper and lower cloth guide rollers. The distance between the two guide rollers is 190-210mm, and the distance between the upper and lower guide rollers is 800-1000mm. This structure has the disadvantages of large distance between the upper and lower rows of cloth guide rollers, easy curling of fabrics when conveying fabrics for washing, poor tension control, and large equipment size. Its washing effect also needs to be improved. Utility Model Content

[0003] The utility model aims to provide an open-width washing unit.

[0004] The technical solution to achieve the purpose of the utility model is: a flat-width water washing unit, which includes a water washing tank, in which several upper cloth guide rollers and several lower cloth guide rollers are installed, the upper cloth guide rollers and the lower cloth guide rollers are arranged alternately up and down in the water washing tank, each of the upper cloth guide rollers is tangent to the two lower cloth guide rollers adjacent to the upper cloth guide roller below, each of the lower cloth guide rollers is an active roller, and each of the upper cloth guide rollers is a passive roller; at least one of the upper cloth guide rollers includes a hollow outer roller, the outer roller is a mesh roller, and the interior of the outer roller is connected to the water supply system through a rotating joint and a water pipe.

[0005] The open-width washing unit realized by the utility model shortens the distance between the upper and lower cloth guide rollers, occupies a small area, and the transition length of the fabric is shortened, which is not easy to curl. The fabric can be tightly wrapped on the roller surface of each cloth guide roller, and the rotating joint inside the upper cloth guide roller is connected to the water supply system, so that the internal spraying of the upper cloth guide roller is realized, and the spraying liquid acts on the fabric through the mesh holes of the outer roller, producing a "water-through-the-cloth" effect, thereby improving the washing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Figure 1 It is a schematic structural diagram of the flat-width washing unit described in an embodiment of the utility model; wherein the arrow represents the cloth threading direction. DETAILED DESCRIPTION

[0007] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0008] like Figure 1As shown, a flat-width washing unit comprises a washing tank 1, in which a plurality of upper cloth guide rollers 2 and a plurality of lower cloth guide rollers 3 are installed, the upper cloth guide rollers 2 and the lower cloth guide rollers 3 are arranged alternately up and down in the washing tank 1, each of the upper cloth guide rollers 2 is tangent to the two lower cloth guide rollers 3 adjacent to the upper cloth guide roller 2, each of the lower cloth guide rollers 3 is an active roller, and each of the upper cloth guide rollers 2 is a passive roller; the upper cloth guide roller 2 comprises a hollow outer roller 21, the outer roller 21 is a mesh roller, and the interior of the outer roller 21 is connected to a water supply system (not shown) through a rotary joint 22 and a water pipe (not shown).

[0009] During operation, the fabric is sequentially passed between the upper fabric guide rollers and the lower fabric guide rollers. The rotary joint in the upper fabric guide roller is connected to the water supply system to realize spraying inside the roller. The spraying liquid impacts the fabric surface through the mesh holes of the outer roller. Since the fabric is tightly wrapped on the roller surfaces of the upper and lower fabric guide rollers, the washing efficiency is high.

[0010] The number of the upper cloth guide rollers with the roller body spraying structure of the utility model can be set according to production needs, and can be only one or several.

[0011] In addition, the flat-width washing unit of the utility model is small in size, and a large number of the flat-width washing units can be accommodated in a chassis of the same volume. In this way, it is convenient to set up several flat-width washing units in the chassis to greatly increase the cloth capacity in the chassis and improve the washing efficiency.

[0012] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
