Description

Technical Field

[0001] The utility model relates to the technical field of pad-steam dyeing of cotton fabrics, in particular to a pad-steam dyeing device for cotton fabrics. Background Art

[0002] Pad dyeing refers to a dyeing method in which the fabric is immersed in liquid and then subjected to roller pressure to allow the dye to penetrate the fabric and remove the excess liquid. The pad dyeing method is to dip the fabric in the dye liquid for a short time, then use a roller to press the dye liquid into the gaps in the fabric, and remove the excess dye liquid to make the dye evenly distributed on the fabric.

[0003] In the utility model patent with the authorization announcement number CN215405239U, a roller dyeing machine is disclosed, including a frame, a roller dyeing tank is opened on the frame, a movable roller and a fixed roller are arranged on the frame, the fixed roller and the movable roller are located above the roller dyeing tank, a No. 1 driving motor is arranged on the frame, the output shaft of the No. 1 driving motor is fixedly connected with the movable roller, a brush roller is arranged on the frame, the brush roller is located above the side of the roller dyeing tank away from the movable roller, and a No. 2 driving motor for driving the brush roller is arranged on the frame. By arranging the brush roller, before the cloth enters the roller dyeing tank, the cloth first passes through the brush roller, and the brush roller cleans the fluff and thread ends on the cloth, so that the cloth is separated from the fluff and thread ends, and the situation of insufficient roller dyeing due to the fluff and thread ends attached to the cloth is avoided as much as possible, thereby improving the roller dyeing quality of the cloth.

DETAILED DESCRIPTION

[0020] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0021] like Figure 1-6 As shown, a cotton fabric pad-steam dyeing device comprises a box body 1, two groups of brush roller devices are symmetrically arranged inside the box body 1, the brush roller device comprises a roller 3, a horizontal bar 4 is arranged in an array on the inner circumference of the roller 3, brush strips 5 are evenly arranged on the upper surface of the horizontal bar 4, elastic washers 6 are arranged at both ends of the roller 3, the washers 6 are located between the inner wall of the roller 3 and the horizontal bar 4, fixing rods 7 are arranged on both sides of the box body 1, and extrusion blocks 8 matched with the washers 6 are arranged at the ends of the fixing rods 7, the cross sections of the roller 3 and the extrusion blocks 8 are both circular, and the central axis of the extrusion blocks 8 is The line is located just above the central axis of the drum 3. A through groove for accommodating the drum 3 is provided on the outer surface of the box body 1. A mounting frame 9 is provided on the outer surface of the through groove. A fixing rod 7 is fixed on the mounting frame 9. Gear rings 10 are provided on the inner sides of both ends of the drum 3. A motor 11 is provided on the outer surface of the mounting frame 9. A gear 12 meshing with the gear ring 10 is provided at the output end of the motor 11. A collecting box 13 is provided on one side of the box body 1. A negative pressure device 14 is provided on the collecting box 13. Suction heads 15 are provided on the upper and lower sides of the box body 1. The negative pressure device 14 is connected to the suction head 15 through a pipe 16.

[0022] This cotton fabric 17 pad-steam dyeing device also includes a cold stack unit, a washing machine, an opener and a dryer, which are all arranged in sequence behind the dyeing machine 2. After the cotton fabric 17 passes through the box 1, it passes through the dyeing machine 2, the cold stack unit, the washing machine, the opener and the dryer in sequence to achieve dyeing and color fixation of the cotton fabric 17. Since the dyeing machine 2, the cold stack unit, the washing machine, the opener and the dryer are all existing technologies, they will not be repeated here.

[0023] Through slots are provided on both sides of the box body 1 to facilitate the cotton fabric 17 to pass through the box body 1 through the through slots.

[0024] The two motors 11 outside the box body 1 rotate in opposite directions. The output shaft of the lower motor 11 rotates in the counterclockwise direction, and the output shaft of the upper motor 11 rotates in the clockwise direction, so that the brush strip 5 on the drum 3 can clean out the cotton wool, thread ends, etc. on the cotton fabric 17 in the opposite direction of the cotton fabric 17.

[0025] The motor 11 is fixed to the box body 1 through the mounting frame 9. When the motor 11 drives the gear 12 to rotate, the gear 12 drives the roller 3 to rotate in the box body 1 by cooperating with the gear ring 10. The gasket 6 is made of rubber or silicone. The gasket 6 is fixed inside the roller 3 and rotates with the roller 3, while the fixing rod 7 and the extrusion block 8 on one side of the mounting frame 9 maintain a relatively static position with the box body 1. When there is no extrusion block 8, the gasket 6 pushes the horizontal bar 4 toward the center position of the roller 3 through its own supporting effect. When there is an extrusion block 8, the gasket 6 can be blocked, and the brush bar 5 can also be prevented from falling from the roller 3. Since the rotation center line of the extrusion block 8 does not coincide with that of the roller 3, when the roller 3 rotates, the same position on the gasket 6 contacts with different positions of the extrusion block 8, which is manifested as the same position of the gasket 6 being repeatedly compressed and expanded. Thereby, the brush strip 5 can be controlled to continuously move inside the drum 3. When the brush strip 5 extends to the outside of the drum 3 to the longest length, the brush strip 5 can contact the cotton fabric 17 and take away the cotton fluff and thread ends on the cotton fabric 17. When this part of the brush strip 5 continues to rotate, the deformation degree of the gasket 6 located at this part of the brush strip 5 gradually decreases, causing the brush strip 5 to move toward the inside of the drum 3. When the brush strip 5 moves to a position close to the suction head 15, the brush strip 5 can completely enter the inside of the drum 3, but still maintain a sliding connection with the drum 3 to facilitate subsequent extension. When the brush strip 5 completely enters the inside of the drum 3, the cotton fluff and thread ends on the brush strip 5 are pushed to the outer surface of the drum 3, and negative pressure is generated inside the collecting box 13 through the negative pressure device 14. Then, the cotton fluff and thread ends on the two drums 3 are collected into the collecting box 13 through the suction head 15 and the pipe 16.

[0026] Furthermore, the distance between the end of the brush bar 5 and the cotton fabric 17 is positively correlated with the length of the brush bar 5 outside the drum 3. The closer the distance between the brush bar 5 and the cotton fabric 17, the longer the length of the brush bar 5 outside the drum 3, ensuring that the brush bar 5 can rotate smoothly and remove cotton wool and thread ends on the cotton fabric 17.

[0027] Furthermore, the end of the brush strip 5 is provided with a thorn-shaped protrusion, which is convenient for capturing cotton wool and thread ends on the cotton fabric 17.

[0028] Furthermore, the brush strip 5 is made of rubber to prevent the brush strip 5 from piercing the cotton fabric 17 .

[0029] Furthermore, the brush strips 5 on the two rollers 3 are staggered. When the brush strips 5 on the rollers 3 are staggered, the distance between the two rollers 3 can be conveniently controlled to prevent the distance between the two rollers 3 from being unable to be further reduced due to the abutment of the brush strips 5. By reducing the distance between the two rollers 3, the friction between the brush strips 5 and the cotton fabric 17 can be increased, thereby increasing the ability and efficiency of capturing cotton wool and thread ends.

[0030] Working principle: When in use, the cotton fabric 17 passes through the box body 1, and the drum 3 is driven to rotate by the motor 11, the gear 12 and the ring gear 10. During the rotation of the drum 3, the washers 6 cooperate with the extrusion blocks 8 to make the horizontal bars 4 on the drum 3 move regularly, and the brush strips 5 on the horizontal bars 4 move regularly between the inside and outside of the drum 3. When the brush strips 5 are fully extended from the outside of the drum 3, the cotton wool and thread ends on the cotton fabric 17 can be captured. When the brush strips 5 are completely hidden inside the drum 3, the friction between the brush strips 5 and the cotton wool and thread ends is reduced or even cannot be directly contacted. At this time, the negative pressure device 14, the suction head 15 and the pipe 16 can directly suck the cotton wool and thread ends from the outer surface of the drum 3, thereby preventing the cotton wool and thread ends from being entangled in the brush strips 5, affecting the subsequent cleaning effect of the cotton wool and thread ends of the cotton fabric 17.

[0031] The device can clean the cotton wool and thread ends on the cotton fabric 17 by controlling the movement of the brush bar 5. At the same time, the friction between the brush bar 5 and the cotton wool and thread ends is reduced or even prevented from directly contacting the cotton wool and thread ends, so that the cotton wool and thread ends can be directly sucked away by the suction head 15, preventing the cotton wool and thread ends from being entangled on the brush bar 5 and affecting the subsequent cleaning effect of the cotton wool and thread ends on the cotton fabric 17. The use effect is good.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
