Description

TECHNICAL FIELD

[0002] In the textile industry, fabric pre-shrinking treatment is the key process to improve the dimensional stability of finished products, especially for cotton, hemp, chemical fiber blended materials and other materials that are prone to shrinkage. The fabric is pre-shrunk in the warp and weft directions to reduce the shrinkage rate of the final product and meet the quality requirements of garment processing. During the dyeing and finishing process, the warp direction of the fabric is subjected to tension, and the bending wave height of the warp direction is reduced, so the fabric may stretch. When the hydrophilic fiber fabric is soaked and wet, the fiber swells, the diameter of the warp and weft yarns increases, the bending wave height of the warp yarns increases, the length of the fabric shortens, and the fabric shrinks. The percentage of the length reduction to the original length is called the shrinkage rate. The finishing process that reduces the shrinkage of the fabric after soaking by physical methods is also called mechanical pre-shrinking finishing.

[0003] For the feeding mechanism of the pre-shrinking machine, in order to achieve better pre-shrinking effect, a pre-amount relaxation structure is generally arranged at the feeding mechanism, a certain amount of fabric relaxation is achieved by arranging a certain amount of protrusions on the surface of the rotating roller, and the protrusions on the surface of the rotating roller have weak adjustability and weak scale adjustment of the relaxation.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0024] Please refer to Figs. 1-3 The utility model discloses a high-precision fabric pre-shrunk finishing machine, including pre-shrunk machine frame 1, the heating bin 2 of pre-shrunk machine frame 1 top part and the pre-shrunk machine frame 1 front end installation two groups of interval distribution feeding roller 3, wherein feeding roller 3 sets two groups, and the side of feeding roller 3 is driven by motor, after the fabric cylinder is placed on feeding roller 3, the end of fabric is dragged to heating bin 2 along pre-adjusting roller 5, there is heating area and patting area in heating bin 2, and drying, cooling and loose area are set behind heating bin 2, and it is the existing basic structure of pre-shrunk machine, not drawn in the drawing.

[0025] Pre-adjusting roller 5 is arranged on the front side of heating bin 2, and pre-adjusting roller 5 is arranged obliquely above feeding roller 3, the side end shaft of pre-adjusting roller 5 is connected with drive bin 4, motor is also arranged in drive bin 4, pre-adjusting roller 5 is rotated by motor, butt joint bottom plate 7 is arranged in the cavity of pre-adjusting roller 5, adjusting roller slot 6 is formed in the surface of pre-adjusting roller 5 and is communicated with the inner cavity of pre-adjusting roller 5, pre-top plate 13 connected with butt joint bottom plate 7 is slidably connected in the slot of adjusting roller slot 6, wherein the top of butt joint bottom plate 7 is provided with bottom plate slot 12, the bottom of pre-top plate 13 can be inserted into the slot of bottom plate slot 12 to combine butt joint bottom plate 7 and pre-top plate 13, in order to strengthen the stability of the connection of butt joint bottom plate 7 and pre-top plate 13, positioning screw hole 14 is formed in the center of the slot of bottom plate slot 12, and positioning jack 15 aligned with positioning screw hole 14 is formed in the surface of pre-top plate 13, locking rod 16 can be inserted into positioning jack 15 and positioning screw hole 14, after the threaded part at the end of locking rod 16 is combined with positioning screw hole 14, pre-top plate 13 can be stably reinforced on the top of butt joint bottom plate 7;

[0026] The top plate 13 is slidably connected in the groove of the adjusting roller groove 6. By moving the top plate 13 longitudinally in the groove of the adjusting roller groove 6, the protruding position of the top plate 13 can be adjusted. The higher the protruding position of the top plate 13, the more the fabric is relaxed by the top plate 13 when the fabric passes the pre-adjusting roller 5. Conversely, the lower the protruding position of the top plate 13, the less the fabric is relaxed. Thus, the relaxation of the fabric can be freely adjusted.

[0027] For adjusting the height of the docking plate 7, a track groove 8 is formed on the side of the docking plate 7 and has an angle with the horizontal. A moving slider 9 is slidably connected in the track groove 8. When the moving slider 9 moves horizontally, the docking plate 7 is forced to move longitudinally, thereby adjusting the protruding position of the top plate 13.

[0028] The pre-adjusting roller 5 is provided with a driving mechanism for driving the moving slider 9 to move horizontally. The driving mechanism includes an adjusting screw 10 and a screw sleeve 11. The adjusting screw 10 is transversely arranged in the pre-adjusting roller 5. The adjusting screw 10 is sleeved with the screw sleeve 11. The front end of the moving slider 9 is fixedly connected with the screw sleeve 11. One end of the adjusting screw 10 extends outward through the pre-adjusting roller 5. By rotating the adjusting screw 10, the screw sleeve 11 moves radially along the adjusting screw 10, thereby driving the moving slider 9 to move horizontally. A plurality of prong holes are formed in the surface of the adjusting screw 10. A screw insertion hole 19 is formed in the bottom of the screw hole. A docking plug 21 is inserted into the screw insertion hole 19. The surface of the docking plug 21 is fixedly connected with a rotating handle 17. By operating the rotating handle 17, the docking plug 21 and the screw insertion hole 19 drive the adjusting screw 10 to rotate.

[0029] A spring portion 20 is arranged between the bottom of the screw insertion hole 19 and the docking plug 21. A plurality of positioning ring holes 18 are arranged in the surface of the pre-adjusting roller 5 and arranged in a ring array. A limiting plug 22 is arranged on the surface of the rotating handle 17 and can be inserted into the positioning ring hole 18. In the initial state, the limiting plug 22 is inserted into the positioning ring hole 18. At this time, the rotating handle 17 cannot be rotated, so that the adjusting screw 10 and the top plate 13 associated with the adjusting screw 10 can be kept stable. When the top plate 13 needs to be adjusted, a part of the rotating handle 17 is pulled outwards, so that the spring portion 20 is stretched. At this time, the front end of the limiting plug 22 is pulled out of the positioning ring hole 18. At this time, the rotating handle 17 can be rotated, thereby rotating the adjusting screw 10.

[0030] The above are only preferred embodiments of the present application, and do not limit the present application, any modification to the technical solutions recorded in the foregoing embodiments, equivalent replacement of part of the technical features, any modification, equivalent replacement, improvement made, all belong to the protection scope of the present application.
