Description

Technical Field

[0001] The present application relates to the technical field of yarn-dyed fabric processing, and in particular to a double-layer yarn-dyed fabric shaping device. Background Art

[0002] In the textile industry, shaping of yarn-dyed fabrics is a key step in ensuring product quality. Conventional shaping devices for single-layer fabrics usually use heating plates and pressure devices to heat and shape the fabric. However, this treatment method makes it difficult to ensure uniform heating and shaping of the two layers of fabric when processing double-layer yarn-dyed fabrics, which is prone to quality problems. Therefore, shaping devices specifically for double-layer yarn-dyed fabrics have begun to appear on the market.

At the same time, the slanting upward horn holes increase the air flow in the drying box, so that the scattered hair is sucked into the slanting upward horn holes.

[0004] However, this patent still has certain shortcomings in actual use. When drying the fabric, it is necessary to rely on the air outlet to divert and guide the hot air transported in the hot air conveying pipe for discharge. The actual inner diameter of the hot air conveying pipe is much smaller than the total coverage area of the air outlet, which makes it difficult for the hot air to enter the outermost air outlet for discharge, thereby affecting the uniformity of the fabric drying and shaping, and there are certain quality problems. In this regard, the present application provides a double-layer color-dyed fabric shaping device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] See also Figures 1 to 4 The present application provides a technical solution: a double-layer color-dyed fabric shaping device, comprising a drying box 1, two supporting frames 2 are fixed to the bottom of the drying box 1, a drying component 300 is installed on the inner side of the drying box 1, and an adsorption component 500 is installed on the top of the drying box 1; through the cooperation between the drying component 300 and the adsorption component 500 inside the drying box 1, the two sides of the fabric can be effectively dried and shaped more evenly, and the layout of the structure allows the fabric to be fully heated during the transportation process. At the same time, with the characteristics of the air flow inside the device, the hot air can flow to a certain extent, thereby preheating the fabric that has just entered the device, and the flowing air is also conducive to improving the drying efficiency, so that it has a comprehensive and efficient drying effect, thereby effectively improving the practicality of the double-layer color-dyed fabric shaping device.

[0032] It should be noted that the inner side of the drying box body 1 is rotatably connected with four transmission rods 401 through bearings, and a transmission roller 402 is fixed to the outer side of the transmission rod 401. The front ends of the two transmission rods 401 on the left side pass through the front side of the drying box body 1 and are fixedly installed with a transmission gear 403. Two fixed blocks 404 are fixed to the front side of the drying box body 1, and a support plate 405 is fixed between the tops of the two fixed blocks 404. A first servo motor 406 is fixedly installed on the top of the support plate 405. The four transmission rods 401 are respectively located on the left and right sides of the drying box body 1, and the corresponding two transmission rollers 402 are symmetrically distributed up and down, and the opposite sides of the corresponding two transmission rollers 402 are in contact with the surface of the color-dyed fabric, so that the color-dyed fabric can move under the rolling guide action between the corresponding two transmission rollers 402.

[0033] In addition, the opposite sides of the two transmission gears 403 are meshed with each other, the output shaft of the first servo motor 406 is fixedly connected to the front side of the top transmission gear 403, the two fixing blocks 404 are respectively located on the left and right sides of the transmission gear 403, and the support plate 405 is located on the front side of the transmission gear 403, so that the first servo motor 406 can stably drive the top transmission gear 403 to rotate, and then drive the bottom transmission gear 403 to rotate through meshing transmission.

[0034] In this embodiment, the drying assembly 300 is a structure for comprehensively and effectively drying double-layer yarn-dyed fabrics.

[0035] like Figure 1 、 Figure 2 and Figure 3 As shown, the drying component 300 includes two mounting holes 301 respectively opened at the top and bottom of the drying box body 1, a fan 302 fixedly installed on the inner side of the mounting hole 301, two dust shields 303 detachably connected to the top and bottom of the drying box body 1, a plurality of rotating cylinders 304 rotatably connected to the inner side of the drying box body 1 through bearings, a heating cylinder 305 fixed between the opposite sides of the two corresponding rotating cylinders 304, two heaters 306 fixedly installed on the front side of the drying box body 1, a plurality of heat pipes 307 fixedly installed on the output end of the heater 306, and a plurality of umbrella-shaped heat sinks 308 fixedly installed on the outside of the heat pipe 307.

[0036] It should be noted that the air outlet surface of the fan 302 is inclined toward the side close to the right side of the drying box body 1, so that the fan 302 can blow out wind to the right side, and the two dust shields 303 are respectively located at the openings on the opposite side of the two mounting holes 301, so that the dust shields 303 can play a role in dust blocking the openings of the mounting holes 301 located to the outside. The front and back sides of the rotating cylinder 304 and the heating cylinder 305 are both open. The number of heating cylinders 305 is ten, and each two is a group. The heating cylinders 305 in the same group are symmetrically distributed up and down, so that the heating cylinders 305 can rotate normally inside the drying box body 1 under the action of the rotating cylinder 304, and can allow the color-woven fabric to be transported through the opposite side of the two heating cylinders 305 in the same group.

[0037] In addition, the number of heat pipes 307 is equal to the number of heating cylinders 305. The ends of the heat pipes 307 pass through the front of the drying box 1 and the interior of the front rotating cylinder 304 and extend to the interior of the corresponding heating cylinder 305. The diameter of the heat pipes 307 is smaller than the inner diameter of the rotating cylinder 304, so that the heat pipes 307 can extend to the interior of the corresponding heating cylinder 305 without affecting the normal rotation of the heating cylinder 305 and the rotating cylinder 304. The umbrella-shaped heat sink 308 is located inside the corresponding heating cylinder 305, so that the umbrella-shaped heat sink 308 can provide an effective heat conduction effect, so that the heating cylinder 305 can be effectively heated.

[0038] In this embodiment, the adsorption component 500 is a structure for adsorbing the floating hairs on the surface of the yarn-dyed fabric.

[0039] like Figure 1 and Figure 4As shown, the adsorption assembly 500 includes a vacuum cleaner 501 fixedly mounted on the top of the drying box 1, a rotating rod 502 rotatably connected to the top of the drying box 1 through a bearing, a rotating disk 503 fixed to the top of the rotating rod 502, a driven bevel gear 504 sleeved on the outside of the rotating rod 502, a lifting block 505 fixed to the top of the drying box 1, a second servo motor 506 fixedly mounted on the top of the lifting block 505, a driving bevel gear 507 fixedly mounted on the output shaft of the second servo motor 506, four guide cylinders 508 respectively fixed to the front and back of the drying box 1, a guide rod 509 slidably connected to the inner side of the guide cylinder 508, a dust suction nozzle 510 fixed between opposite sides of the two corresponding guide rods 509, a connecting plate 511 fixed between the front ends of the two guide rods 509 on the front, a linkage rod 512 hinged to the top of the connecting plate 511 through a pin, and two fixed pipes 513 fixedly mounted on the input end of the vacuum cleaner 501.

[0040] It should be noted that the right side of the active bevel gear 507 is meshed with the left side of the driven bevel gear 504, so that the active bevel gear 507 can drive the driven bevel gear 504 to rotate, and the front and back sides of the guide cylinder 508 are both open. The front and back sides of the drying box body 1 are respectively provided with two guide holes that are connected to the interior of the corresponding two guide cylinders 508, so that the guide rod 509 can move normally inside the corresponding guide cylinder 508 and the guide hole.

[0041] In addition, the two dust suction nozzles 510 are symmetrically distributed up and down, and the openings of the two dust suction nozzles 510 are respectively located at the top and bottom of the cloth, so that the dust suction nozzles 510 can remove dust and absorb hair on the surface of the cloth. The side of the connecting rod 512 away from the connecting plate 511 is hinged to the top of the rotating disk 503 through a pin shaft, so that both ends of the connecting rod 512 can rotate in the horizontal direction, and then when the rotating disk 503 rotates, the connecting plate 511 can be driven to move through the connecting rod 512.

[0042] At the same time, the end of the fixed tube 513 passes through the back of the corresponding guide rod 509 and is fixedly connected to the outside of the corresponding dust suction nozzle 510, and the interior of the fixed tube 513 and the interior of the corresponding dust suction nozzle 510 are connected, so that the vacuum cleaner 501 can perform adsorption through the fixed tube 513 and the corresponding dust suction nozzle 510.

[0043] The working principle of the above embodiment is:

[0044] When drying and shaping the double-layer yarn-dyed fabric, the fabric is passed in sequence between the opposite sides of the two right transmission rollers 402, between the opposite sides of the two dust suction nozzles 510, between the opposite sides of the top and bottom heating cylinders 305, and between the opposite sides of the two left transmission rollers 402. The first servo motor 406 is started to drive the corresponding transmission gear 403 to rotate. Under the meshing transmission action of the transmission gear 403, the two left transmission rods 401 are rotated, so that the left two transmission rollers 402 can drive the fabric to move, providing a certain amount of power for the movement of the fabric. The heater 306 is started so that it can heat the inside of the heating cylinder 305 through the corresponding heat pipe 307. The umbrella-shaped heat sink 308 can improve the efficiency of heat conduction, so that the heating cylinder 305 can play a good heat conduction role, so that the surface of the fabric passing through the heating cylinder 305 can be evenly heated. When the air is hot, the fan 302 is started to supply air to the inside of the drying box 1, so that the air inside the drying box 1 can circulate to a certain extent, thereby improving the drying efficiency, and can also transport the hot air to the right side of the drying box 1, so as to preheat the cloth that has just entered. The second servo motor 506 is started to drive the active bevel gear 507 to rotate, so that the driven bevel gear 504 is rotated, and then the rotating rod 502 is rotated and drives the rotating disk 503 to rotate, which can pull or push the connecting plate 511 to move under the action of the connecting rod 512, so that the guide rod 509 can slide on the inner side of the corresponding guide cylinder 508, and can also drive the dust suction nozzle 510 to move, start the vacuum cleaner 501, and suck dust from the surface of the cloth through the fixed tube 513 and the corresponding dust suction nozzle 510, thereby achieving the effect of absorbing hair, so as to improve the overall quality.

[0045] Compared with the existing technology, the double-layer color-dyed fabric shaping device can effectively dry and shape both sides of the fabric more evenly through the coordinated use of the drying component 300 and the adsorption component 500 inside the drying box 1. Through the layout of the structure, the fabric can be fully heated during the transportation process. At the same time, the characteristics of the air flow inside the device are combined to enable the hot air to flow to a certain extent, thereby preheating the fabric that has just entered the device. The flowing air is also conducive to improving the drying efficiency, so that it has a comprehensive and efficient drying effect, thereby effectively improving the practicality of the double-layer color-dyed fabric shaping device, and solving the problem that the fabric on the outside cannot be effectively dried during actual use of the existing continuous shaping dryer.
