[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, washing machines must be used for thorough cleaning. Traditional ordinary tight flat 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. In order to reduce the liquid carrying rate, a heavy-duty small rolling car is also installed at the cloth outlet of the last grid of the flat washing tank. This structure has the disadvantages of large distance between the upper and lower rows of cloth guide rollers, large spacing between the transition cloth guide rollers between adjacent washing tanks, easy curling of fabrics when conveying fabrics for washing, poor tension control, and large equipment investment.

[0015] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. Example 1

[0016] like Figure 1 As shown, a micro-tension washing machine with low liquid carryover rate comprises two washing tanks 1, the two washing tanks 1 are arranged adjacent to each other horizontally, and a partition 2 is arranged between the two washing tanks 1; a plurality of cloth guide rollers 3 are installed in each washing tank 1, and the cloth guide rollers 3 are arranged alternately up and down in the washing tank 1, and each cloth guide roller 3 located at the top is tangent to the two adjacent cloth guide rollers 3 below the cloth guide roller 3, the cloth guide rollers 3 located at the bottom are active rollers, and the cloth guide rollers 3 located at the top are passive rollers; a transition cloth guide roller 4 is installed between adjacent washing tanks 1, and the transition cloth guide roller 4 is arranged tangent to the two closest cloth guide rollers 3 in the adjacent washing tanks 1 in sequence.

[0017] During operation, the fabric 100 is sequentially passed between the cloth guide rollers 3 and the transition cloth guide roller 4. Since the fabric 100 is tightly wrapped around the roller surfaces of the upper and lower cloth guide rollers, it shuttles in an S-shaped manner. The cloth guide rollers located above are driven to rotate by the two cloth guide rollers adjacent to the cloth guide rollers below the cloth guide rollers. The tension of the fabric is small and remains constant, which is easy to control and not easy to curl. During the conveying process of the fabric, the fabric is squeezed and rubbed by the tangent cloth guide rollers, and the washing efficiency of the fabric is better. The transition cloth guide roller 4 presses the fabric on the two tangent cloth guide rollers 3 to reduce the fabric liquid carrying rate. This structure is suitable for use when the movement extension of the fabric is not too long or the fabric density requirement is not high. Example 2

[0018] like Figure 2 As shown, a micro-tension washing machine with low liquid carrying rate includes three washing tanks 1, each of which is stacked vertically in sequence, and the conveying paths of each of the washing tanks 1 are connected. A plurality of cloth guide rollers 3 are installed in each of the washing tanks 1, and the cloth guide rollers 3 are arranged in an up-and-down staggered manner in the washing tank 1, and each of the cloth guide rollers 3 located at the top is tangent to the two adjacent cloth guide rollers 3 below the cloth guide roller 3, and each of the cloth guide rollers 3 located at the bottom is an active roller, and each of the cloth guide rollers 3 located at the top is a passive roller; a transition cloth guide roller unit 5 is installed between adjacent washing tanks 1.

[0019] like Figure 3As shown, the transition cloth guide roller unit 5 includes a transition cloth guide roller 51 and a lifting device 52, the transition cloth guide roller 51 has a roller shaft 511, there are three transition cloth guide rollers 51, each of the transition cloth guide rollers 51 and the two closest cloth guide rollers in the adjacent washing tanks are arranged in sequence in a vertical direction; the lifting device 52 includes a roller shaft limiting plate 521 symmetrically installed at both ends of the roller shaft, the roller shaft limiting plate 521 is movably installed in a chassis (not shown) through a lifting drive mechanism 522, the roller shaft limiting plate 521 includes an upright limiting plate body 5211, and three strip holes 5212 are spaced apart from top to bottom on the limiting plate body 5211, and the horizontal position of the strip holes is the most The lower side wall is the bottom wall 52121 of the strip hole, and both ends of each roller shaft 511 pass through the corresponding strip hole 5212 and are connected to a driving mechanism (not shown) that drives the transition cloth guide roller 51 to rotate; the distance between the roller shaft 511 of the transition cloth guide roller 51 located at the uppermost layer and the bottom wall 52121 of the strip hole where the roller shaft 511 is located is A, the distance between the roller shaft 511 of the transition cloth guide roller 51 located in the middle and the bottom wall 52121 of the strip hole where the roller shaft 511 is located is B, and the distance between the roller shaft 511 of the transition cloth guide roller 51 located at the lowermost layer and the bottom wall 52121 of the strip hole where the roller shaft 511 is located is C, and A<B<C.

[0020] Furthermore, the lifting drive mechanism 522 is a lifting cylinder, and the lifting cylinder has a piston rod 5221 , and the piston rod 5221 is oriented vertically downward, and the roller limit plate 521 is fixedly installed on the free end of the piston rod 5221 .

[0021] The working principle of the transition cloth guide roller unit implemented in this embodiment is as follows:

[0022] 1) When the washing machine is working, the piston rod of the lifting cylinder is in the extended state, such as Figure 2 As shown, each transition cloth guide roller is arranged tangentially in the vertical direction, and the roller shaft of each transition cloth guide roller is connected to the driving mechanism. The driving mechanism drives the transition cloth guide roller to rotate, and the fabric is tightly wound around each transition cloth guide roller and transmitted upward, and is not easy to curl.

[0023] 2) When cloth needs to be threaded, each of the transition cloth guide rollers is disengaged from the driving mechanism, the piston rod of the lifting cylinder is retracted, and the roller shaft limit plate is lifted until the roller shaft of each of the transition cloth guide rollers is located at the bottom wall of the corresponding strip hole. Figure 4 As shown, a cloth threading gap is formed between each of the transition cloth guide rollers.

[0024] The number of transition cloth guide rollers described in the utility model is not limited to that described in the embodiment, and is set according to the scale of the specific washing machine equipment. Usually, only one transition cloth guide roller is required between the horizontal washing tanks, and a large-diameter transition cloth guide roller can also be set for two groups of vertically stacked washing tanks; the transition cloth guide roller unit improves the convenience of threading cloth with multiple tangent transition cloth guide rollers; the number of the strip holes is usually matched with the number of transition cloth guide rollers; the lifting drive mechanism is not limited to the lifting cylinder, and can also be a conventional lifting structure in the mechanical field such as screw lifting. The driving mechanism that drives the transition cloth guide roller to rotate is also a prior art, which is not the innovation point of the utility model and will not be described here.

[0025] 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.
