Description
Technical Field
[0001] The utility model relates to the field of dyeing and finishing equipment, in particular to a multi-tank three-roll calender. Background Art
[0002] For the post-finishing processing of textiles, various post-finishing auxiliaries are mostly impregnated by a calender first, and then enter a stenter for stretching, drying and finishing. An ordinary calender is only equipped with one tank for impregnating auxiliaries on the fabric once. However, in actual production, the fabrics are mostly stacked in a cloth cart before impregnation. The result of stacking is that the upper-layer fabrics in the cloth cart have a low water content rate, while the lower-layer fabrics have a high water content rate, and there is a large difference in the water content rate between the front and back of the same cart of fabrics. If the auxiliaries are directly impregnated, the amount of auxiliaries carried by the fabrics will be uneven, thus affecting the product quality. In view of this, it is necessary to improve the existing calender structure so that the auxiliaries are evenly distributed on the fabric. Content of the Utility Model
[0003] The purpose of the utility model is to provide a multi-tank three-roll calender.
[0004] The technical solution for realizing the purpose of the utility model is: a multi-tank three-roll calender, which includes a rotatable first calender roll, a second calender roll and a third calender roll.

[0007] Further, the pressing device includes two first pressing swing arms, two second pressing swing arms, two first telescopic pressing air bags, and two second telescopic pressing air bags. One first pressing swing arm and one first telescopic pressing air bag are respectively arranged at both ends of the first roll. One end of each first pressing swing arm is hinged to the frame, and the other end of the first pressing swing arm is hinged to one end of the first telescopic pressing air bag on the same side as the first pressing swing arm. The other end of the first telescopic pressing air bag is hinged to the frame. The first roll is rotatably installed between the two first pressing swing arms. One second pressing swing arm and one second telescopic pressing air bag are respectively arranged at both ends of the third roll. One end of each second pressing swing arm is hinged to the frame, and the other end of the second pressing swing arm is hinged to one end of the second telescopic pressing air bag on the same side as the second pressing swing arm.

[0013] The multi-tank three-roller calender realized by the present utility model enables the fabric to complete two padding operations through three rollers of one calender. A liquid storage area is formed at the first padding point between the first roller and the second roller, enabling the fabric just leaving the padding point to immediately absorb the auxiliary liquid, which is beneficial to the penetration effect of the auxiliary liquid on the fiber, enabling the fabric to uniformly maintain a certain liquid content and enter the subsequent dyeing and finishing processes, improving the production efficiency and product quality of the dyeing and finishing processing, and simplifying the mechanical structure and improving the operation reliability of the equipment; meanwhile, multiple liquid supply tanks can pad different process liquids, having good process flexibility and meeting the process treatment requirements of new fabrics.

[0018] The following further describes the preferred embodiments of the present utility model with reference to the accompanying drawings.
[0019] Embodiment 1
[0020] As Figure 1 and Figure 2As shown in the figure, a multi-trough three-roll calender includes a rotatable first roll 1, a second roll 2, and a third roll 3. The first roll 1, the second roll 2, and the third roll 3 are sequentially and tangentially arranged from bottom to top within a frame 100. Among them, the second roll 2 is a driving roll, and both the first roll 1 and the third roll 3 are driven rolls; below the two sides of the first roll 1 in the horizontal direction, a first trough 4 and a second trough 5 are respectively installed. The side where the first trough 1 is located is the fabric feeding end side 1001. The first roll 1, the second roll 2, and the third roll 3 are inclined relative to the vertical direction towards the fabric feeding end side 1001. The fabric 200 feeds from the fabric feeding end side 1001, sequentially passes through the first trough 4, the first roll 1, the liquid supplement trough 5, the second roll 2, and the third roll 3, and then discharges the fabric. A number of fabric guiding rolls 6 are arranged on the traveling route of the fabric 200. A first wire dividing roll 7 is installed at the discharging end side of the fabric 200 from the first trough 4. A second wire dividing roll 8 is installed at the feeding end side of the fabric 200 between the second roll 2 and the third roll 3. A groove 11 for storing liquid is formed at the discharging end side of the first roll 1 and the second roll 2. Above the groove 11, a liquid supplement mechanism 9 for supplementing liquid to the groove 11 is installed.
[0021] Further, a pressing device 10 is respectively installed at both ends of the first roll 1. The pressing device 10 includes two first pressing swing arms 101, two second pressing swing arms 102, and two pressing cylinders 103. One first pressing swing arm and one pressing cylinder are respectively arranged at both ends of the first roll. The pressing cylinder 103 has a head end 1031 and a tail end 1032. The axis of the pressing cylinder 103 is parallel to the axis connection line of the first roll 1 and the second roll 2. One end of the first pressing swing arm 101 is hinged to the frame 100, and the other end of the first pressing swing arm 101 is hinged to the tail end 1032 of the pressing cylinder 103 on the same side as the first pressing swing arm 101. The first roll 1 is rotatably installed between the two first pressing swing arms 101. One end of the second pressing swing arm 102 is hinged to the frame 100, and the other end of the second pressing swing arm 102 is hinged to the head end 1031 of the pressing cylinder 103 on the same side as the second pressing swing arm 102. The third roll 3 is rotatably installed between the two first pressing swing arms 101.
[0022] Further, the liquid supplement mechanism 9 includes a spray pipe 91 and a water supply pipe 92. One end of the water supply pipe 92 is communicated with the spray pipe 91, and the other end of the water supply pipe 92 is communicated with the second trough 5. A circulation pump 93 is installed on the water supply pipe 92.
[0023] In this embodiment, the first roller, the second roller, and the third roller are arranged obliquely, and their axes are on the same inclined straight line. A liquid storage groove is formed between the first roller and the second roller. The second roller in the middle is the driving roller and is driven by a reduction motor. The first roller and the third roller are driven rollers, and the first roller and the third roller are driven by a pressing device to contact the second roller to form a squeezing effect.
[0024] During operation, the fabric is guided by a fabric guiding roller into the first trough, immersed in the liquid, and then enters the first nip formed by the tangency of the second roller and the first roller through the first filament separating roller. After leaving the first nip, it enters the liquid storage area of the groove between the second roller and the first roller. When the fabric fibers are flattened and then rebound out of the first nip, they immediately absorb the dye solution in the groove, achieving the process effect that the dye solution penetrates well into the fiber structure. The liquid replenishing mechanism uses the dye in the liquid replenishing trough to perform cyclic spraying to continuously replenish the groove with liquid; subsequently, the fabric descends and is immersed in the liquid replenishing trough to further absorb the dye solution to reach a saturated state, and then enters the second nip formed by the third roller and the second roller through the guiding roller and the second filament separating roller, squeezing out the excess dye solution on the fabric, and enabling the fabric to uniformly maintain a certain liquid content and enter the subsequent dyeing and finishing process. The two independent hoppers of the present utility model can dip and roll different process liquids, have good process flexibility, and meet the process treatment requirements of new fabrics.
