Description

Technical Field

[0001] The utility model relates to the field of dyeing and finishing equipment, in particular to a straight roller washing device. 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 certain finishing processes, a washing machine must be used for thorough cleaning. The utility model patent of China Patent No. 202321080468.7 discloses a cleaning and drying device for a printing and dyeing washing machine, which includes a washing box and a drying box, wherein an ultrasonic transducer is provided at the bottom of the washing box, and a cleaning guide roller is provided inside the washing box. The device emits a high-frequency oscillation signal through an ultrasonic generator, which is then converted into a high-frequency mechanical oscillation by a transducer and propagated into the cleaning liquid, and the shock wave generated by the "cavitation effect" of ultrasonic waves in the liquid is used to remove dirt on the surface of the printed and dyed fabric, so as to achieve the purpose of cleaning the printed and dyed fabric. However, due to the large spacing between the cleaning guide rollers, the fabric is in a free state in the water and will float with the ultrasonic source, resulting in a weakening of the ultrasonic force and poor actual washing effect. Utility Model Content

[0003] The utility model aims to provide a straight roller washing device.

[0004] The technical solution for achieving the purpose of the utility model is: a straight roller washing device, which includes a washing tank, in which a plurality of cloth guide rollers are installed, the cloth guide rollers are arranged alternately up and down in the washing tank, each of the cloth guide rollers located above is tangent to the two adjacent cloth guide rollers below the cloth guide roller, each of the cloth guide rollers located below is an active roller, and each of the cloth guide rollers located above is a passive roller; at least one of the cloth guide rollers located below includes an outer roller and an inner roller arranged coaxially, the outer roller is a mesh roller, the inner roller is sleeved in the outer roller, and the roller surface of the inner roller is provided with a plurality of protrusions along the circumference of the inner roller.

[0005] Furthermore, the inner roller is a polygonal column.

[0006] Furthermore, the inner roller comprises a cylindrical roller body, the surface of the roller body is provided with a plurality of ridges at equal intervals along the circumference of the roller body, the length direction of the ridges is parallel to the axial direction of the roller body, and the surface of the ridges away from the roller body is an arc surface.

[0007] Furthermore, the cloth guide roller located at the top is a mesh roller.

[0008] The straight roller washing device realized by the utility model shortens the distance between the upper and lower cloth guide rollers, thereby shortening the transition length of the fabric, making it less likely to curl, and the fabric can be tightly wrapped on the roller surface of each cloth guide roller, and the inner roller of the cloth guide roller located below can stir the liquid in the outer roller when it rotates, and then act on the fabric through the mesh holes of the outer roller, producing a "water-through-the-cloth" effect, thereby improving the washing efficiency.

[0010] Figure 2 This is a schematic structural diagram of the straight roller washing device described in Example 1 of the utility model.

[0011] The arrows represent the direction of fabric threading. DETAILED DESCRIPTION

[0012] The preferred embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings. Example 1

[0013] like Figure 1 As shown, a straight roller washing device comprises a washing tank 1, in which a plurality of cloth guide rollers 2 are installed, and the cloth guide rollers 2 are arranged alternately up and down in the washing tank 1, and each of the cloth guide rollers 2 located at the top is tangent to the two adjacent cloth guide rollers 2 below the cloth guide roller 2, and each of the cloth guide rollers 2 located at the bottom is an active roller, and each of the cloth guide rollers 2 located at the top is a passive roller; the cloth guide roller located at the top is a mesh roller, and the cloth guide roller 2 located at the bottom comprises an outer roller 21 and an inner roller 22 which are coaxially arranged, and the outer roller 21 is a mesh roller, and the inner roller 22 is sleeved in the outer roller 21, and the inner roller 22 is a hexagonal prism.

[0014] During operation, the fabric is sequentially passed between the fabric guide rollers, and the inner roller of the fabric guide roller located below rotates to stir the liquid in the outer roller. The 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. Example 2

[0015] The difference between Example 2 and Example 1 is that the inner roller 22 includes a cylindrical roller body 10, and the surface of the roller body 10 is provided with four ridges 101 at equal intervals along the circumference of the roller body 10, the length direction of the ridges 101 is parallel to the axial direction of the roller body 10, and the surface of the ridges 101 facing away from the roller body 10 is an arc surface.

[0016] The roller surface of the inner roller of the utility model is provided with a plurality of protrusions along the circumference of the inner roller, and the shape of the protrusions is not limited to the polygonal prism protrusions shown in the embodiment, and it can also be a wave roller, etc., by providing a plurality of protrusions along the circumference of the inner roller to stir the liquid; the cloth guide roller located above is not limited to a mesh roller.

[0017] 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.
