Description

Technical Field

[0001] This application relates to the field of textile printing and dyeing technology, specifically to a fabric output device for an overflow dyeing machine. Background Technology

[0002] Overflow dyeing machines are widely used equipment in the textile printing and dyeing industry. They dye fabrics by circulating dye liquor. With the textile industry's increasing requirements for dyeing efficiency and fabric quality, the performance optimization of overflow dyeing machines has become a research hotspot. The fabric output stage of overflow dyeing machines directly affects the post-processing quality and production efficiency of the fabric.

[0003] However, most existing overflow dyeing machines do not have a flattening mechanism in their fabric output device. After the fabric is squeezed and drained, the difference in humidity at both ends of the squeeze roller may cause uneven distribution of fiber elasticity and tension, which can easily lead to wrinkles, twists or local deformations, affecting the yield of subsequent finishing and printing processes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a fabric output device for an overflow dyeing machine, which has advantages such as increasing the yield rate. It solves the problem that most existing overflow dyeing machine fabric output devices do not have a flattening mechanism. After squeezing and draining, the fabric at both ends of the squeezing roller may have uneven fiber elasticity and tension distribution due to the difference in humidity, which can easily cause wrinkles, twists or local deformations, affecting the yield rate of subsequent setting, printing and other processes.

[0005] To achieve the above objectives, this application provides the following technical solution: a fabric outlet device for an overflow dyeing machine, comprising a water collection plate, with upright plates fixedly connected to both sides of the upper end of the water collection plate, two sliding grooves arranged in a mirror image inside each of the two upright plates, two sliding rods arranged in a mirror image fixedly connected to each of the four sliding grooves, a first water-pressing roller and a first leveling roller rotatably connected between the two upright plates, sliders slidably connected to the outer walls of each pair of sliding rods, two springs arranged in a mirror image fixedly connected to the upper ends of each of the four sliding grooves, a second water-pressing roller and a second leveling roller rotatably connected between each pair of the four sliders, two support arms arranged in a mirror image fixedly connected to one side of the upper end of the water collection plate, a first guide roller rotatably connected between the two support arms, and a guide plate fixedly connected to one side of the water collection plate.

[0006] The above-described scheme utilizes a wavy outer wall design for both the first and second water-pressing rollers, increasing the contact area with the fabric and improving the squeezing and drainage effect. This ensures that more water is expelled from the fabric after squeezing. Through a linkage mechanism between the slider and spring, the second water-pressing roller and the second leveling roller automatically adjust their spacing according to the fabric thickness, ensuring uniform and appropriate pressure on the fabric during leveling. The flat surfaces of the first and second leveling rollers flatten the fabric through pressure, allowing it to be quickly leveled after drainage. This avoids wrinkles caused by fabric looseness or humidity changes, improving the fabric's flatness. The first guide roller guides the wet fabric between the first and second water-pressing rollers, ensuring accurate positioning of the fabric before squeezing and drainage, reducing the risk of fabric deviation. This device, through efficient squeezing, drainage, and leveling, reduces wrinkles and deformation of the fabric during the discharge process, lowers the defect rate, and improves product quality.

[0007] Furthermore, two first motors arranged in a mirror image are fixedly connected to one side of the upright plate, and two second motors are fixedly connected to one side of each of the two sliders. The output ends of the two first motors are fixedly connected to the first water-pressing roller and the first leveling roller through one end of the upright plate via couplings. The output ends of the two second motors are fixedly connected to the second water-pressing roller and the second leveling roller through one end of the slider via couplings.

[0008] With the above scheme, two first motors drive the first water-pressing roller and the first leveling roller respectively, and two second motors drive the second water-pressing roller and the second leveling roller respectively. Since the first water-pressing roller, the second water-pressing roller, the first leveling roller, and the second leveling roller can all rotate, it is used to prevent the fabric from slipping or stretching during the conveying process.

[0009] Furthermore, two first support plates arranged in a mirror image are fixedly connected to the upper end of the water collection plate, and a second guide roller is rotatably connected between the two first support plates.

[0010] With the above scheme, the second guide roller is located after the drainage and leveling process, and is used to guide the fabric into the subsequent collection device to prevent the position from shifting during the conveying process.

[0011] Furthermore, two mirror-distributed second support plates are fixedly connected to the upper end of the water collection plate away from the support arm. A third motor is fixedly connected to one side of each second support plate, and a drive gear is fixedly connected to the output end of the third motor. Rotation slots are opened on the upper ends of the two second support plates, and a fixing block is fixedly connected to the upper ends of each of the two second support plates by bolts. A collection roller is rotatably connected between the two second support plates and the fixing block. Two mirror-distributed baffles are fixedly connected to the outer wall of the collection roller, and rotating rings are fixedly connected to both ends of the outer wall of the collection roller. A driven gear is fixedly connected to one side of the collection roller.

[0012] With the above scheme, the third motor drives the collection roller to rotate by meshing the driving gear with the driven gear of the collection roller. The fixing block is connected to the second support plate by bolts to form a detachable structure. When replacing the collection roller, the fixing block can be removed by simply loosening the bolts, which reduces the replacement time of the collection roller.

[0013] Furthermore, the two rotating rings are rotatably disposed inside the rotating groove, and the driving gear meshes with the driven gear.

[0014] With the above scheme, the rotating ring is embedded in the rotating groove to increase the stability of the collecting roller when rotating. The collecting roller can be disassembled and replaced by the cooperation of the driving gear and the driven gear.

[0015] Furthermore, the bottom end of the water collection plate is provided with multiple water outlet grooves arranged in a straight line array, the bottom end of the water collection plate is fixedly connected to a water collection tank, the bottom end of one side of the water collection tank is fixedly connected to a drain pipe, and a valve is fixedly sleeved on the outer wall of the drain pipe.

[0016] With the above scheme, the water outlet is arranged in a linear array, and the liquid on the water collection plate is guided to flow into the water collection tank along a predetermined path by the inclined setting of the bottom of the water collection plate, so as to avoid the liquid stagnation on the surface of the water collection plate and reduce the risk of secondary pollution. The water collection tank can store a large amount of wastewater to ensure continuous operation of the equipment. The valve fixedly sleeved on the outer wall of the drain pipe can control the wastewater discharge speed by adjusting the opening degree.

[0017] Furthermore, the bottom ends of each of the multiple springs are fixedly connected to the slider in pairs.

[0018] With the above scheme, springs are symmetrically arranged in pairs on the upper end of the slider to form a pressure compensation device, which can adapt to the thickness of the fabric while discharging different fabrics.

[0019] Furthermore, all four sliders are slidably disposed on the inner wall of the chute, with the first water-pressing roller and the second water-pressing roller corresponding to each other, and the first leveling roller and the second leveling roller corresponding to each other.

[0020] With the above scheme, the four sliders slide in the groove, and the gap between the first water pressure roller, the second water pressure roller, and the first water pressure roller and the second water pressure roller can be adjusted by changing the position of the sliders.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: The fabric discharge device of this overflow dyeing machine features a corrugated outer wall design for the first and second water-pressing rollers, increasing the contact area with the fabric and improving the squeezing and drainage effect. This ensures that more water is discharged from the fabric after squeezing. Through a linkage mechanism between a slider and a spring, the second water-pressing roller and the second leveling roller automatically adjust their spacing according to the fabric thickness, ensuring that the fabric receives uniform and appropriate pressure during the leveling process. The surfaces of the first and second leveling rollers are flat, and the pressure flattens the fabric, allowing it to be quickly leveled after drainage. This avoids wrinkles caused by fabric looseness or humidity changes, improving the fabric's flatness. The first guide roller guides the wet fabric between the first and second water-pressing rollers, ensuring the accurate positioning of the fabric before squeezing and drainage, reducing the risk of fabric deviation. This device, through efficient squeezing, drainage, and leveling, reduces wrinkles and deformation of the fabric during the discharge process, lowers the defect rate, and improves product quality.

[0025] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of an overflow dyeing machine includes a fabric outlet device comprising a water collection plate 1, with upright plates 2 fixedly connected to both sides of the upper end of the water collection plate 1. Each upright plate 2 has two mirror-arranged sliding grooves 3 inside, and each of the four sliding grooves 3 has two mirror-arranged sliding rods 4 fixedly connected inside.

Each pair of sliding blocks 7 is rotatably connected to a second water-pressing roller 9 and a second leveling roller 10. The wavy outer walls of the first water-pressing roller 5 and the second water-pressing roller 9 increase the contact area with the fabric. The squeezing and drainage effect is improved, ensuring that more water can be discharged from the fabric after squeezing. Through the linkage mechanism of slider 7 and spring 8, the second water-pressing roller 9 and the second leveling roller 10 can automatically adjust the spacing according to the thickness of the fabric, ensuring that the fabric is subjected to uniform and appropriate pressure during the leveling process. Two support arms 11 arranged in a mirror distribution are fixedly connected to one side of the upper end of the water collection plate 1. The first guide roller 12 is rotatably connected between the two support arms 11. The first guide roller 12 is set to guide the wet fabric into the space between the first water-pressing roller 5 and the second water-pressing roller 9, ensuring that the fabric is accurately positioned before squeezing and drainage, and reducing the risk of fabric deviation. A guide plate 13 is fixedly connected to one side of the water collection plate 1. The guide plate 13 is used to guide the wastewater dripping from the fabric into the interior of the water collection plate 1.

[0026] Please see Figure 1 , Figure 3 and Figure 4Two mirror-distributed first motors 14 are fixedly connected to one side of a vertical plate 2. Two second motors 15 are fixedly connected to one side of each of the two sliders 7. The output ends of the two first motors 14 pass through one end of the vertical plate 2 and are fixedly connected to the first water-pressing roller 5 and the first leveling roller 6 via couplings. The output ends of the two second motors 15 pass through one end of the sliders 7 and are fixedly connected to the second water-pressing roller 9 and the second leveling roller 10 via couplings. The two first motors 14 drive the first water-pressing roller 5 and the first leveling roller 6 respectively, and the two second motors 15 drive the second water-pressing roller 9 and the second leveling roller 10 respectively. The first water-pressing roller 5, the second water-pressing roller 9, the first leveling roller 6, and the second leveling roller 10 can all rotate to prevent the fabric from slipping or stretching during transport. Two mirror-distributed first support plates 16 are fixedly connected to the upper end of a water collection plate 1. A second guide roller 17 is rotatably connected between the two first support plates 16. The second guide roller 17 is located after the drainage and leveling processes and is used to guide the fabric into the subsequent collection device to prevent misalignment during transport. To prevent displacement, two mirror-distributed second support plates 18 are fixedly connected to the upper end of the water collection plate 1, away from the support arm 11. A third motor 19 is fixedly connected to one side of each second support plate 18, and a drive gear 20 is fixedly connected to the output end of the third motor 19. Rotation grooves 21 are formed on the upper ends of the two second support plates 18, and fixing blocks 22 are fixedly connected to the upper ends of both second support plates 18 by bolts. A collection roller 23 is rotatably connected between the two second support plates 18 and the fixing blocks 22, and a fixed element is fixedly connected to the outer wall of the collection roller 23. Two baffles 24 are arranged in a mirror image. Rotating rings 25 are fixedly connected to both ends of the outer wall of the collecting roller 23. A driven gear 26 is fixedly connected to one side of the collecting roller 23. The third motor 19 meshes with the driven gear 26 of the collecting roller 23 through the driving gear 20 to drive the collecting roller 23 to rotate. The fixing block 22 is connected to the second support plate 18 by bolts to form a detachable structure. When replacing the collecting roller 23, the fixing block 22 can be removed by simply loosening the bolts, so that the collecting roller 23 can be disassembled, reducing the replacement time of the collecting roller 23.

[0027] Please see Figure 1 , Figure 2 and Figure 5Two rotating rings 25 are rotatably disposed inside the rotating groove 21. The driving gear 20 meshes with the driven gear 26. The rotating rings 25 are embedded in the rotating groove 21 to increase the stability of the collecting roller 23 during rotation. The collecting roller 23 can be disassembled and replaced through the cooperation of the driving gear 20 and the driven gear 26. Multiple water outlet grooves 27 arranged in a straight array are opened through the bottom end of the water collecting plate 1. A water collection tank 28 is fixedly connected to the bottom end of the water collecting plate 1. A drain pipe 29 is fixedly connected to one side of the bottom end of the water collection tank 28. A valve 30 is fixedly sleeved on the outer wall of the drain pipe 29. The water outlet grooves 27 are arranged in a straight array. The inclined arrangement of the bottom end of the water collecting plate 1 guides the liquid on the water collecting plate 1 to flow into the water collection tank 28 along a predetermined path, avoiding the liquid from stagnating on the surface of the water collecting plate 1. To reduce the risk of secondary pollution, the water collection tank 28 can store a large amount of wastewater, ensuring continuous operation of the equipment. The valve 30 fixedly sleeved on the outer wall of the drain pipe 29 can control the wastewater discharge speed by adjusting the opening. Multiple springs 8 are fixedly connected to the bottom of the slider 7 in pairs. The springs 8 are symmetrically arranged in pairs on the upper end of the slider 7 to form a pressure compensation device. While discharging different fabrics, it can adapt to the fabric thickness. The four sliders 7 are slidably set on the inner wall of the slide groove 3. The first water pressing roller 5 and the second water pressing roller 9 correspond to each other. The first leveling roller 6 and the second leveling roller 10 correspond to each other. The four sliders 7 slide in the slide groove 3. By changing the position of the sliders 7, the gap between the first water pressing roller 5, the second water pressing roller 9 and the first water pressing roller 5 and the second water pressing roller 9 can be adjusted.

[0028] In this embodiment, the fabric outlet device of the overflow dyeing machine uses a wavy outer wall design for the first and second water-pressing rollers 5 and 9 to increase the contact area with the fabric, improve the squeezing and drainage effect, and ensure that more water is discharged from the fabric after squeezing. Through the linkage mechanism of the slider 7 and the spring 8, the second water-pressing roller 9 and the second leveling roller 10 can automatically adjust the spacing according to the thickness of the fabric, ensuring that the fabric is subjected to uniform and appropriate pressure during the leveling process. The surfaces of the first leveling roller 6 and the second leveling roller 10 are flat, and the fabric is flattened by pressure, so that the fabric can be quickly flattened after drainage, avoiding wrinkles caused by fabric looseness or humidity changes, and improving the flatness of the fabric. The first guide roller 12 is set to guide the wet fabric into the space between the first and second water-pressing rollers 5 and 9, ensuring that the fabric is accurately positioned before squeezing and drainage, reducing the risk of fabric deviation. This device reduces wrinkles and deformation of the fabric during the discharge process through efficient squeezing, drainage and leveling, reduces the defect rate and improves product quality.

[0029] The working principle of the above embodiments is as follows: The wet fabric is first guided by the first guide roller 12 into the squeezing zone composed of the first corrugated water-pressing roller 5 and the second water-pressing roller 9. The corrugated outer wall increases the contact area with the fabric. Under the adaptive pressure of the slider 7 pushed by the spring 8, dynamic squeezing of fabrics of different thicknesses is achieved, squeezing the water to the water collection plate 1. Then the fabric enters the leveling mechanism composed of the first leveling roller 6 and the second leveling roller 10. The first leveling roller and the second leveling roller 10 rotate synchronously under the drive of the motor, eliminating wrinkles and stabilizing tension. The dehydrated and leveled fabric is guided by the second guide roller 17 and finally wound up by the collecting roller 23. Its baffle 24 prevents the fabric from deviating to the side. The gear transmission mechanism enables quick disassembly and assembly, which facilitates the replacement of the collecting roller 23 and achieves continuous output. The wastewater generated during the squeezing process flows into the water collection tank 28 through the inclined surface of the water collection plate 1 and the water outlet trough 27. The valve 30 controls the centralized discharge.
