Description

Technical Field

[0001] The invention relates to the field of weft yarn processing, in particular to a weft yarn dyeing and drying device. Background Art

[0002] Weft dyeing is widely used in the production of various textiles, such as clothing, home textiles, industrial textiles, etc. Through weft dyeing, textiles can be given rich colors and patterns, which improves the added value and market competitiveness of products.

[0003] During the dyeing process, the weft yarn absorbs a large amount of dye solution, which contains water and dye. The drying process is required to remove excess water from the weft yarn to prevent the residual water from causing the yarn to mold, deteriorate or affect subsequent processing. In the drying process, the dye molecules will further penetrate into the fiber and chemically bond or physically adsorb with the fiber molecules, thereby improving the fastness and uniformity of the dyeing. In addition, through drying, the fibers in the yarn will become more compact, thereby improving the strength and wear resistance of the yarn. At the same time, drying can also eliminate the wrinkles and distortions of the yarn during the dyeing process, and improve the straightness and glossiness of the yarn.

[0004] At present, the traditional drying room is generally used in the production process to dry the weft yarn after dyeing. That is, the operator hangs the dyed weft yarn on the weft yarn rack, and then transfers the weft yarn rack to the drying room and leaves it to stand for a period of time to dry the weft yarn. This process has some disadvantages:

[0005] 1. The temperature in different areas of the drying room is different, which makes the color and glossiness of the dried weft yarn different, resulting in product quality differences.

For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0046] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0047] The embodiment of the present invention provides a weft yarn dyeing and drying device, see Figures 1 to 9 The weft yarn dyeing and drying device includes a bellows 101, at both ends of which fans 102 are fixedly installed, the two fans 102 are used to form convection wind in the bellows 101, a plurality of drying boxes 103 are fixedly installed on the bellows 101 along its length direction, and an adjusting mechanism 300 is installed at the bottom of the drying box 103, and the adjusting mechanism 300 is used to connect the bellows 101 with the drying box 103.

[0048] An air inlet mechanism 200 is installed at the bottom of the adjusting mechanism 300, and the air inlet mechanism 200 includes an air inlet 201, an adjusting box 202, an electric telescopic rod 203, a ventilation slot 204, and a heating unit 210. The bottom of the adjusting mechanism 300 is fixedly connected and communicated with the first end of the air inlet 201, and the second end of the air inlet 201 is slidably configured in the first end of the adjusting box 202 and communicated with it. The first end of the adjusting box 202 is hinged to the bottom of the adjusting mechanism 300, and the side of the adjusting box 202 is hinged to the first end of the electric telescopic rod 203, and the second end of the electric telescopic rod 203 is hinged to the bottom of the adjusting mechanism 300. A plurality of ventilation slots 204 are evenly opened on the upper surface of the adjusting box 202 along its length direction, and the plurality of ventilation slots 204 connect the air box 101 with the adjusting box 202. A heating unit 210 is installed inside the adjusting box 202, and the heating unit 210 is used for air heating.

[0049] A mounting mechanism 400 is coaxially mounted inside the drying box 103, and the mounting mechanism 400 includes a mounting cylinder 401, on the outer surface of which the dyed weft yarn to be dried is placed, and a plurality of through holes are evenly opened on the side wall of the mounting cylinder 401 along its circumference, thereby connecting the interior of the drying box 103 with the interior of the mounting cylinder 401, and the top of the mounting cylinder 401 is connected to the exhaust chamber 106, and the exhaust chamber 106 is fixedly mounted on the top of the drying box 103.

[0050] A first temperature sensor 108 is installed on the top of the drying box 103, and a humidity detector 107 is installed on the side of the exhaust chamber 106. The fan 102, the humidity detector 107, the first temperature sensor 108, the air inlet mechanism 200, the adjustment mechanism 300, and the installation mechanism 400 are respectively connected to the controller 500 for signal connection, and the controller 500 is fixedly installed on the side of the drying box 103.

[0051] The drying box 103 has doors 104 hingedly mounted on the front and rear sides thereof, and a handle 105 is fixedly mounted on the door 104 to facilitate the operator to place and take out the weft yarn after opening the door 104 .

[0052] Among them, the side shape of the air inlet 201 is fan-shaped, the side shape of the first end of the regulating box 202 is fan-shaped, and the hinge axis of the first end of the regulating box 202 coincides with the axis of the air inlet 201 and the fan-shaped shape of the regulating box 202, so that the sliding of the regulating box 202 relative to the air inlet 201 can smoothly adjust the angle of the regulating box 202 relative to the horizontal direction.

[0053] The angle between the wind direction in the regulating box 202 and the wind box 101 is an acute angle, which facilitates the introduction of the convection wind in the wind box 101 into the regulating box 202 .

[0054] In the above embodiment, after the operator installs the dyed weft yarn to be dried in the drying box 103, the controller 500 first controls the fans 102 installed on both sides of the wind box 101 to start, thereby forming convection wind in the wind box 101. The convection wind enters the interior of the regulating box 202 through the ventilation slots 204. After being heated by the heating unit 210 in the regulating box 202, the convection wind enters the drying box 103 through the air inlet 201 and the regulating mechanism 300 in turn. At this time, the first temperature sensor 108 measures the temperature of the hot air entering the drying box 103, and feeds back the temperature measurement result to the controller 500. The controller 500 adjusts the heating power of the heating unit 210 according to the temperature measurement result.

[0055] The hot air entering the drying box 103 dries the dyed weft yarn installed on the outer surface of the installation cylinder 401. In this process, the hot air passes through the weft yarn and the through holes opened on the side wall of the installation cylinder 401 to enter the inner cavity of the installation cylinder 401, and is discharged outward through the exhaust cavity 106 at the top of the installation cylinder 401. Since the hot air entering the exhaust cavity 106 carries a large amount of water vapor, the humidity of the air in the exhaust cavity 106 is measured by the humidity detector 107 at this time, and the dryness of the dyed weft yarn inside the drying box 103 can be determined; when the humidity is high, it means that the weft yarn contains When the water volume is high, the controller 500 controls the electric telescopic rod 203 to extend, so that the angle between the regulating box 202 and the wind direction in the bellows 101 becomes larger, thereby increasing the air intake and accelerating the drying speed of the dyed weft yarn. At the same time, the heating power of the heating unit 210 is adjusted synchronously to ensure the drying efficiency of the dyed weft yarn. When the humidity is low, it means that the weft yarn is basically dried. At this time, maintaining a high drying temperature will cause the weft yarn to deform or discolor, affecting the product quality. Therefore, the controller 500 controls the heating unit 210 to adjust the heating power to ensure product quality.

[0056] As a further explanation of the above embodiments of the present invention, see Figure 5 The regulating mechanism 300 includes an air duct 301, a cylindrical sleeve 302, a cylindrical core 303, a through groove 304, and a second motor 305. The air duct 301 is fixedly connected to the bottom of the drying box 103, and the two ends of the air duct 301 are respectively connected to the two sides of the bottom of the drying box 103. The middle part of the air duct 301 is fixedly connected and connected to the first end of the air inlet 201, and the side of the air duct 301 is fixedly connected and connected to the cylindrical sleeve 302. A cylindrical core 303 rotating along the cylindrical sleeve 302 is sealed inside the cylindrical sleeve 302. The cylindrical core 303 is provided with a through groove 304 along its radial direction. The through groove 304 can connect the middle and end parts of the air duct 301. The cylindrical core 303 is coaxially fixed with the output end of the second motor 305 that seals and passes through the side of the air duct 301.

[0057] The structure consisting of the cylindrical sleeve 302 , the cylindrical core 303 , the through slot 304 , and the second motor 305 is symmetrically distributed in two groups about the center of the air duct 301 .

[0058] Air inlet cavities 110 are respectively provided on both sides of the drying box 103, and the bottoms of the two air inlet cavities 110 are respectively connected to the two ends of the air duct 301, and a plurality of air inlet grooves 111 are evenly opened on the sides of the air inlet cavities 110 close to the mounting tube 401. A first temperature sensor 108 is installed on the top of one of the air inlet cavities 110, and a second temperature sensor 109 is installed on the top of the other air inlet cavity 110, and the second temperature sensor 109 is connected to the controller 500 by signal.

[0059] In the above embodiment, after the hot air enters the air duct 301 through the air inlet 201, it is transported to the air inlet cavity 110 located on both sides of the drying box 103 through the two ends of the air duct 301, and the hot air is evenly distributed and blown toward the mounting tube 401 through a plurality of air inlet grooves 111 opened on the side of the air inlet cavity 110.

[0060] When the hot air enters the air inlet cavity 110 located on both sides of the drying box 103, the temperatures in the two air inlet cavities 110 are measured respectively by the first temperature sensor 108 and the second temperature sensor 109, and the measurement results are fed back to the controller 500. When the temperature measured by the first temperature sensor 108 is higher than the preset temperature range, the controller 500 controls the second motor 305 close to the first temperature sensor 108 to drive the cylindrical core 303 to rotate, and the air intake volume is reduced; when the temperature measured by the first temperature sensor 108 is lower than the preset temperature range, the controller 500 controls the second motor 305 close to the first temperature sensor 108 to drive the cylindrical core 303 to rotate, and the air intake volume is increased; the temperature adjustment method on the second temperature sensor 109 side is exactly the same as that on the first temperature sensor 108 side.

[0061] In this way, the temperature at different positions in the drying box 103 can be controlled within a preset temperature range, so that the ambient temperature of the dyed weft yarn is uniform during the drying process, avoiding product quality differences such as discoloration and deformation caused by temperature differences.

[0062] As a further explanation of the above embodiments of the present invention, see Figure 3 , 4 The mounting mechanism 400 also includes a third motor 402 and a suspension shaft 403. The bottom of the drying box 103 is fixedly connected to the third motor 402. The third motor 402 is signal-connected to the controller 500. The output end of the third motor 402 is sealed and passes through the bottom of the drying box 103 and is coaxially fixed to the bottom of the mounting cylinder 401. A plurality of suspension shafts 403 are evenly fixed on the outer surface of the mounting cylinder 401. The suspension shafts 403 are used to suspend or install the dyed yarn to be dried.

[0063] Through the above structure, when the operator installs the dyed yarn on the suspension shaft 403 and starts drying, the controller 500 controls the third motor 402 to drive the installation cylinder 401 to rotate, so that the positions of the dyed yarn installed at different positions on the outer surface of the installation cylinder 401 can be continuously changed, thereby achieving more uniform drying and improving product quality.

[0064] As a further explanation of the above embodiments of the present invention, see Figure 6 The air inlet mechanism 200 also includes a swing leaf 205, a gear 206, a rack 207, a guide groove 208, and an electric cylinder 209. The swing leaf 205 is rotatably installed in the ventilation groove 204, and the swing leaf 205 can block the adjustment box 202. The installation axis of the swing leaf 205 passes through the side wall of the adjustment box 202 and is coaxially fixed with the gear 206. The gear 206 is meshed with the rack 207. The rack 207 is arranged in the guide groove 208 and moves along it. The guide groove 208 is opened on the side of the adjustment box 202. The rack 207 is fixedly connected to the output end of the electric cylinder 209. The electric cylinder 209 is connected to the controller 500 signal, and the electric cylinder 209 is fixedly installed on the side of the adjustment box 202.

[0065] The above structure controls the air intake volume through the cooperation between the swing leaf 205 and the ventilation slot 204. When the air intake volume needs to be increased, the electric cylinder 209 drives the rack 207 to slide along the length direction of the guide slot 208, so that the rack 207 further drives the gear 206 and the swing leaf 205 to rotate, so that the angle between the swing leaf 205 and the ventilation slot 204 increases, and the gap between the ventilation slot 204 and the swing leaf 205 increases, thereby increasing the air intake volume; conversely, the electric cylinder 209 drives the rack 207 in the opposite direction to slide, which will reduce the air intake volume. Therefore, through the above structure, the air intake volume of the drying device can be adjusted more flexibly, and the drying speed in the drying box 103 can be controlled more accurately.

[0066] As a further explanation of the above embodiments of the present invention, see Figure 7 , 8 9. The heating unit 210 includes a first motor 211, a screw 212, a slider 213, a guide rail 214, a conductive connector 215, a conductive post 216, a heating tube 217, a wire post 218, a first terminal 219, and a second terminal 220;

[0067] The first motor 211 is fixedly connected to the side wall of the regulating box 202, the first motor 211 is signal-connected to the controller 500, the output end of the first motor 211 is coaxially fixed to the first end of the screw 212, the screw 212 is threadedly connected to the slider 213, the slider 213 is slidingly contacted and configured in the guide rail 214, the guide rail 214 is fixedly installed inside the regulating box 202, the slider 213 is fixedly connected to the conductive connector 215, the conductive connector 215 is in sliding contact with the side of the conductive pile 216, a plurality of conductive piles 216 are uniformly arranged in sequence along the length direction of the guide rail 214, each conductive pile 216 is fixedly connected to the heating tube 217 through a wire post 218, the first conductive pile 216 is fixedly connected to the second terminal 220, the guide rail 214 is fixedly connected to the first terminal 219, the first terminal 219 and the second terminal 220 are electrically connected to the positive and negative poles of the power supply respectively.

[0068] Among them, the conductive connector 215 is a spherical structure, and several conductive posts 216 are provided with arc-shaped grooves on the side close to the slider 213. The conductive connector 215 is arranged in the arc-shaped groove. This structure facilitates the sliding contact between the conductive connector 215 and the conductive posts 216, thereby achieving the conductive effect between the conductive connector 215 and different conductive posts 216.

[0069] Among them, Fig. 9 As shown, the wire post 218 is disposed perpendicularly to the guide rail 214 .

[0070] Among them, the conductive pile 216, the conductive connector 215, the guide rail 214 and the slider 213 are made of conductive materials, and the screw 212 is made of insulating material, so that the first motor 211 can drive the position of the slider 213 relative to the guide rail 214 through the screw 212, thereby switching the connected conductive pile 216.

[0071] The current connected to the first terminal 219 and the second terminal 220 remains unchanged.

[0072] In the above embodiment, when the heating power of the heating unit 210 needs to be adjusted, the controller 500 controls the forward and reverse rotation of the first motor 211, thereby adjusting the position of the slider 213 relative to the guide rail 214 through the threaded connection relationship between the slider 213 and the screw 212, so that the connected conductive pile 216 is switched, such as Fig. 9 As shown, when the conductive connector 215 moves upward, the length of the heating tube 217 connected to the heating circuit is increased through the conductive pile 216 and the wire column 218. Without changing the current, the power of the heating part 210 is increased, and its power is proportional to the length of the connected heating tube 217, which facilitates the precise control and adjustment of the heating temperature.
