Description

Technical Field

[0001] The invention belongs to the technical field of printing and dyeing, and in particular relates to a cloth drying device and a drying method thereof. Background Art

[0002] Fabric is a common decorative material. This includes various fabrics, including synthetic carpets, non-woven wall coverings, linen, nylon, colored tape, flannel, and more. Fabric plays a significant role in decorative displays and is often a crucial element in the overall retail space. Extensive use of fabric for wall coverings, partitions, and backgrounds can also create a compelling commercial space display style.

[0003] In the process of fabric production, the fabric needs to be cleaned, printed, dyed, dried and other processes. Printing and dyeing, also known as dyeing and finishing, is a fabric processing method. It is also a general term for dyeing, printing, finishing, washing, etc. With the development of scientific knowledge, printing and dyeing technology has been continuously improved. At present, large-scale mechanized production has been formed in China, and some environmentally friendly and low-carbon printing and dyeing products have gradually appeared. Printed and dyed fabrics need to be dried after dyeing in the dye vat to ensure the effect and quality of printing and dyeing.

[0004] As mentioned in the cloth drying machine with patent number CN108413751 B, the cloth needs to be dried during the production process. In the existing drying process, the cloth is directly passed through a dehydrator for dehydration before being dried. However, the cloth can only be dehydrated once in the dehydrator, and the cloth still contains a large amount of water before drying. Therefore, when drying, the drying efficiency of the cloth is poor when the cloth enters the drying oven for drying, and the drying time is long. Summary of the Invention

[0005] The purpose of the present invention is to provide a cloth drying device and a drying method thereof in order to solve the above-mentioned technical problems, thereby preventing the internal structure of the cloth from being damaged under continuous high temperature, ensuring the quality of the cloth, and improving the drying efficiency.

[0006] In view of this, the present invention provides a cloth drying device, comprising:

[0007] An oven, wherein an inlet and an outlet are respectively provided at both ends of the oven, and cloth guiding devices are provided at the inlet and outlet of the oven, wherein the cloth guiding devices guide the cloth from the inlet to the outlet, and the cloth guiding devices at the inlet of the oven are capable of dehydrating the cloth;

[0008] A heating plate, which is arranged in the oven to increase the temperature in the oven;

[0009] There are multiple heating rollers, which are arranged in a zigzag shape from the entrance to the exit. The cloth passes through each heating roller from the entrance to the exit. Each heating roller is provided with a heating resistance wire to increase the temperature of the heating roller surface.

[0010] In this technical solution, the moisture content of the fabric entering the oven can be reduced by dehydrating the fabric, thereby reducing the drying pressure of the oven on the fabric, reducing the drying duration and drying temperature, and preventing the internal structure of the fabric from being damaged under continuous high temperature, thereby ensuring the quality of the fabric and improving the drying efficiency. In addition, the temperature of the heating roller gradually increases, which can also gradually heat up the fabric for drying, preventing excessively high temperatures from continuously acting on the fabric and affecting the fabric quality.

[0011] Furthermore, the cloth guiding device includes:

[0012] a first guide roller, the first guide roller being rotatably disposed on a first roller seat, and a first passive bevel gear being coaxially disposed on an end portion of the first guide roller;

[0013] a second guide roller, the second guide roller being rotatably disposed on a second roller seat, and a second passive bevel gear being coaxially disposed on an end portion of the second guide roller;

[0014] A rotating shaft, the rotating shaft being rotatably mounted on the cloth guide seat, the rotating shaft being sleeved with a first driving bevel gear and a second driving bevel gear circumferentially fixedly connected to the rotating shaft, the rotating shaft being connected to a circumferential rotation power source and capable of circumferential rotation;

[0015] Among them, the first guide roller and the second guide roller are parallel to each other, a cloth passing gap is formed between the first guide roller and the second guide roller, the rotating shaft is perpendicular to the axis of the first guide roller and the second guide roller, and the first active bevel gear and the second active bevel gear are respectively engaged with the first passive bevel gear and the second passive bevel gear.

[0016] In the present technical solution, the rotating shaft is rotated circumferentially by a circumferential rotation power source, so that the first active bevel gear and the second active bevel gear are rotated circumferentially, and the first passive bevel gear and the second passive bevel gear drive the first guide roller and the second guide roller to make synchronous circumferential rotation in opposite directions. The cloth passes through the cloth-passing gap, so that the two first guide rollers and the second guide rollers with opposite directions can drive the cloth forward, realizing the function of guiding the cloth.

[0017] Furthermore, the first roller seat is fixedly arranged on the cloth guide seat, the second roller seat is slidably arranged on the cloth guide seat, the second roller seat is fixedly connected to the end of the adjusting screw, the adjusting screw is perpendicular to the axis of the second guide roller and is spirally connected to the cloth guide seat, the second roller seat is slidably connected to the rotating shaft and is fixedly connected to the end of the second active bevel gear, and the adjusting screw can make the second roller seat slide to adjust the size of the cloth gap.

[0018] In this technical solution, by rotating the adjusting screw to move the adjusting screw, the second roller seat is driven to move so that the second guide roller approaches or moves away from the first guide roller. When the second guide roller approaches the first guide roller, that is, the cloth passing gap becomes smaller and is smaller than the cloth thickness, the first guide roller and the second guide roller can squeeze the cloth so that the moisture on the cloth is squeezed out, thereby achieving the purpose of dehydrating the cloth.

[0019] Furthermore, a water receiving box is provided on the cloth guiding seat, and the water receiving box is used to receive the water squeezed out of the cloth.

[0020] Furthermore, the cloth near the outlet in the oven is transferred horizontally, and a thread end cutting device is provided below the cloth, and the thread end cutting device is used to cut off the thread ends on the cloth.

[0021] Furthermore, the thread cutting device includes a cutting seat, which is provided with:

[0022] The winding roller is rotatably arranged on the cutting seat and is located directly below the cloth and in contact with the cloth. The winding roller is perpendicular to the cloth transmission direction and both ends of the winding roller extend beyond the cloth width. The cutting seat is also provided with a winding motor, which is connected to the winding roller to rotate the winding roller. The winding roller is provided with a pressure sensor.

[0023] The ironing knife is arranged on the side of the winding roller close to the outlet and is arranged parallel to the bottom of the cloth. A heating resistance wire is arranged inside the ironing knife. The end of the ironing knife is connected to the pushing cylinder, which can push the ironing knife to move closer to or away from the cloth;

[0024] Among them, the pressure sensor can transmit signals to the controller, which can control the start and stop of the winding motor and the start and stop of the fabric transmission, as well as the extension and retraction of the cylinder piston and the on and off of the hot knife heating resistance wire.

[0025] In this technical solution, the winding motor controls the rotation of the winding roller. When there are thread ends under the cloth and they are wound around the winding roller, the pressure sensor on the winding roller will be under pressure, and the signal will be transmitted to the controller. The controller controls the winding motor to stop rotating and stops the cloth from being transported. Then, the controller controls the ironing knife heating resistor wire to energize and heat up, and controls the cylinder piston to extend to move the ironing knife upward and control the ironing knife to approach the bottom of the cloth. The increase in the temperature of the ironing knife will cut off the thread ends and melt the thread ends. After removing the thread ends on the cloth, the ironing knife resets and the ironing knife heating resistor wire stops energizing.

[0026] Furthermore, a wire breaking structure is provided on the winding roller, and the wire breaking structure includes a notch opened along the axis of the winding roller, a wire breaking cylinder is fixedly provided inside the winding roller, and a wire breaking knife is provided at the protruding end of the wire breaking cylinder piston, and the wire breaking knife corresponds to the notch, and the controller can control the extension and retraction of the wire breaking cylinder piston.

[0027] In this technical solution, after the hot knife melts the thread end, there is still fabric thread wound on the winding roller. The controller controls the wire cutting cylinder piston to extend, driving the wire cutting knife to move toward the notch, which can cut the fabric thread wound on the winding roller. After the fabric thread is broken, the wire cutting knife retracts and returns to its original position. When the pressure sensor senses that there is no pressure on the winding roller, the controller controls the winding motor to restart and controls the fabric to resume transmission.

[0028] Furthermore, a shaking-off device is provided at the end of the winding roller, which can cause the broken fabric line to be shaken off the winding roller, and the shaking-off device includes:

[0029] A shaking-off seat, wherein the shaking-off seat is fixedly arranged at a section of the winding roller away from the cutting seat;

[0030] A shaking-off shaft, wherein the shaking-off shaft is slidably arranged on the shaking-off seat, the shaking-off shaft is perpendicular to the axis of the winding roller, a transmission tooth is arranged on the shaking-off seat along the axis direction, both ends of the shaking-off shaft extend out of the shaking-off seat and are provided with limit blocks, a spring is arranged between the limit block of the shaking-off shaft close to the winding roller and the shaking-off seat, and when the spring is in a natural state, the end of the shaking-off shaft is pressed on the winding roller;

[0031] An incomplete gear is rotatably arranged on the shake-off seat and located below the transmission teeth. The teeth on the incomplete gear can mesh with the transmission teeth on the shake-off shaft. The axis of the incomplete gear is perpendicular to the shake-off shaft. The incomplete gear is connected to the circumferential rotation power source and can rotate circumferentially.

[0032] In this technical solution, the circumferential rotating power source causes the incomplete gear to rotate. When the teeth on the incomplete gear rotate to engage with the transmission teeth on the shaking-off shaft, the shaking-off shaft will move away from the winding roller, and the spring will be squeezed. When the incomplete gear continues to rotate so that the teeth on it are no longer engaged with the transmission teeth on the shaking-off shaft, the spring will cause the shaking-off shaft to move and reset, causing the end of the shaking-off shaft to hit the winding roller. The winding roller will shake when it is hit, and the debris and fabric line on the winding roller will be shaken off, preventing the pressure sensor from being affected. At the same time, the shaking-off shaft reciprocates away from and close to the winding roller, and there will be a period of time when it is not in contact with the winding roller during the rotation of the winding roller. This can increase the service life of the winding roller and the shaking-off shaft.

[0033] Furthermore, a junction box is provided below the winding roller, and the junction box is provided with a wire arrangement pipe, which is connected to the suction pump.

[0034] In this technical solution, the suction pump keeps the cable duct at a negative pressure at all times, so that the fabric wires can be sucked out of the cable duct to the outside of the oven after falling into the junction box.

[0035] Furthermore, the drying method of the cloth drying equipment comprises the following steps:

[0036] Step S1: The size of the cloth-passing gap is adjusted by adjusting the screw, so that the inlet cloth-guiding device can guide the cloth and squeeze and dehydrate it, and the water receiving box receives the water squeezed out of the cloth;

[0037] Step S2: The fabric is conveyed from the inlet to the outlet and heated and dried by heating rollers with gradually increasing temperatures;

[0038] Step S3: During step S2, the thread ends on the fabric are melted by a thread cutting device near the exit;

[0039] Step S4: cutting the fabric line wound on the winding roller by the wire breaking structure, and then shaking off the broken fabric line from the winding roller by the shaking-off device;

[0040] Step S5: After the fabric line falls into the junction box, it is sucked out from the cable duct to the outside of the oven.

[0041] The beneficial effects of the present invention are:

[0042] 1. Dehydrating the fabric can reduce the humidity of the fabric entering the drying oven, reduce the drying pressure of the oven on the fabric, shorten the drying time and temperature, prevent the internal structure of the fabric from being damaged under continuous high temperature, ensure the quality of the fabric, and improve the drying efficiency. In addition, the temperature of the heating roller gradually increases, which can also gradually heat up the fabric during drying, preventing excessively high temperature from continuously acting on the fabric and affecting the fabric quality.

[0043] 2. The rotating shaft is rotated circumferentially by a circumferential rotation power source, so that the first driving bevel gear and the second driving bevel gear are rotated circumferentially, and the first passive bevel gear and the second passive bevel gear drive the first guide roller and the second guide roller to make synchronous circumferential rotation in opposite directions. The cloth passes through the cloth gap, and the two first guide rollers and the second guide rollers with opposite directions can drive the cloth forward to achieve the function of guiding the cloth.

[0044] 3. By rotating the adjusting screw to move the adjusting screw, the second roller seat is driven to move so that the second guide roller approaches or moves away from the first guide roller. When the second guide roller approaches the first guide roller, that is, the cloth passing gap becomes smaller and is smaller than the cloth thickness, the first guide roller and the second guide roller can squeeze the cloth so that the moisture on the cloth is squeezed out, thereby achieving the purpose of dehydrating the cloth.

[0045] 4. After the hot knife melts the thread end, there is still fabric thread wound on the winding roller. The controller controls the wire cutting cylinder piston to extend, driving the wire cutting knife to move toward the notch, which can cut the fabric thread wound on the winding roller. After the fabric thread is broken, the wire cutting knife retracts and returns to its original position. When the pressure sensor senses that there is no pressure on the winding roller, the controller controls the winding motor to restart and control the fabric to resume transmission.

[0046] 5. The circumferential rotation power source causes the incomplete gear to rotate. When the teeth on the incomplete gear rotate to engage with the transmission teeth on the shake-off shaft, the shake-off shaft will move away from the winding roller, and the spring will be squeezed. When the incomplete gear continues to rotate so that the teeth on it are no longer engaged with the transmission teeth on the shake-off shaft, the spring will cause the shake-off shaft to move and reset, causing the end of the shake-off shaft to hit the winding roller. The winding roller will shake when it is hit, and the debris and fabric line on the winding roller will be shaken off to prevent the pressure sensor from being affected. At the same time, the shake-off shaft reciprocates away from and close to the winding roller, and there will be a period of time when it is not in contact with the winding roller during the rotation of the winding roller. This can increase the service life of the winding roller and the shake-off shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] Example 1:

[0061] like Figure 1-2 As shown, a fabric drying device includes an oven 1, a heating plate 2, and a heating roller 3. The oven 1 is provided with an inlet 4 and an outlet 5 at each end, respectively. A fabric guide 6 is provided at each of the inlet 4 and outlet 5 of the oven 1. The fabric guide 6 guides the fabric from the inlet 4 to the outlet 5 and dehydrates the fabric. The heating plate 2 is provided within the oven 1 to increase the temperature within the oven 1. A plurality of heating rollers 3 are provided, arranged in a zigzag pattern from the inlet 4 to the outlet 5. The fabric passes through each heating roller 3 from the inlet 4 to the outlet 5. Each heating roller 3 is provided with a heating resistor to increase the surface temperature of the heating roller 3. By dehydrating the cloth, the humidity of the cloth entering the drying oven 1 can be reduced, the drying pressure of the drying oven 1 on the cloth can be reduced, the drying duration and drying temperature can be shortened, and the internal structure of the cloth can be prevented from being damaged under continuous high temperature, thereby ensuring the quality of the cloth and improving the drying efficiency. In addition, the temperature of the heating roller 3 is gradually increased, which can also gradually heat up the cloth for drying, preventing excessively high temperature from continuously acting on the cloth and affecting the cloth quality.

[0062] like Figure 1-3As shown, the cloth guiding device 6 includes a first guide roller 7, a second guide roller 8 and a rotating shaft 9. The first guide roller 7 is rotatably mounted on a first roller seat 10, and a first passive bevel gear 11 is coaxially mounted on the end of the first guide roller 7; the second guide roller 8 is rotatably mounted on a second roller seat 13, and a second passive bevel gear 14 is coaxially mounted on the end of the second guide roller 8; the rotating shaft 9 is rotatably mounted on a cloth guiding seat 15, and a first active bevel gear 16 and a second active bevel gear 17 are sleeved on the rotating shaft 9 and fixedly connected to the rotating shaft 9 in a circumferential direction. The rotating shaft 9 is connected to a circumferential rotation power source and can rotate circumferentially; the first guide roller 7 and the second guide roller 8 are parallel to each other, and a cloth-passing gap 18 is formed between the first guide roller 7 and the second guide roller 8. The rotating shaft 9 is perpendicular to the axes of the first guide roller 7 and the second guide roller 8, and the first active bevel gear 16 and the second active bevel gear 17 are respectively engaged with the first passive bevel gear 11 and the second passive bevel gear 14. The rotating shaft 9 is rotated circumferentially by a circumferential rotation power source, so that the first driving bevel gear 16 and the second driving bevel gear 17 are rotated circumferentially, and the first passive bevel gear 11 and the second passive bevel gear 14 drive the first guide roller 7 and the second guide roller 8 to make synchronous circumferential rotation in opposite directions. The cloth passes through the cloth gap 18 through the first guide roller 7 and the second guide roller 8 with opposite directions, which drives the cloth to move forward and realizes the function of guiding the cloth.

[0063] The first roller seat 10 is fixedly set on the cloth guide seat 15, and the second roller seat 13 is slidably set on the cloth guide seat 15. The second roller seat 13 is fixedly connected to the end of the adjusting screw 19. The adjusting screw 19 is perpendicular to the axis of the second guide roller 8 and is spirally connected to the cloth guide seat 15. The second roller seat 13 is slidably connected to the rotating shaft 9 and is fixedly connected to the end of the second active bevel gear 17. The adjusting screw 19 is set to enable the second roller seat 13 to slide and adjust the size of the cloth gap 18. By rotating the adjusting screw 19, the adjusting screw 19 moves and drives the second roller seat 13 to move so that the second guide roller 8 approaches or moves away from the first guide roller 7. When the second guide roller 8 approaches the first guide roller 7, that is, the cloth gap 18 becomes smaller and is less than the thickness of the cloth, the first guide roller 7 and the second guide roller 8 can squeeze the cloth so that the moisture on the cloth is squeezed out, thereby achieving the purpose of dehydrating the cloth.

[0064] The cloth guide seat 15 is provided with a water receiving box 20 for receiving the water squeezed out of the cloth.

[0065] Example 2:

[0066] like Figure 2 As shown, the cloth near the outlet 5 in the oven 1 is transferred horizontally, and a thread cutting device 21 is provided below the cloth to cut off the thread ends on the cloth. Figure 4-6As shown, the thread cutting device 21 includes a cutting seat 22 , on which a winding roller 23 and a hot knife 24 are provided. The winding roller 23 is rotatably arranged on the cutting seat 22 and is located directly below the fabric and is in contact with the fabric. The winding roller 23 is perpendicular to the fabric transmission direction and the two ends of the winding roller 23 extend beyond the two sides of the fabric width. The cutting seat 22 is also provided with a winding motor 25. The winding motor 25 is connected to the winding roller 23 to rotate the winding roller 23. The winding roller 23 is provided with a pressure sensor, and the sensing range of the pressure sensor is the fabric width range; the ironing knife 24 is arranged on the side of the winding roller 23 close to the outlet 5 and is arranged parallel to the bottom of the fabric. A heating resistance wire is provided in the ironing knife 24, and the end of the ironing knife 24 is connected to the pushing cylinder 26, which can push the ironing knife 24 to move closer to or away from the fabric; the pressure sensor can transmit signals to the controller, and the controller can control the start and stop of the winding motor 25 and the start and stop of the fabric transmission, and can also control the extension and retraction of the piston of the pushing cylinder 26 and the power on and off of the heating resistance wire of the ironing knife 24. The winding motor 25 controls the rotation of the winding roller 23. When there are thread ends under the cloth and they are wound around the winding roller 23, the pressure sensor on the winding roller 23 will be under pressure, and the signal will be transmitted to the controller. The controller controls the winding motor 25 to stop rotating and stop the cloth from being transported. Then the controller controls the heating resistance wire of the ironing knife 24 to be energized and heated, and controls the piston of the push cylinder 26 to extend so that the ironing knife 24 moves upward and controls the ironing knife 24 to be close to the bottom of the cloth. The increase in the temperature of the ironing knife 24 will cut off the thread ends and melt the thread ends. After removing the thread ends on the cloth, the ironing knife 24 resets and the heating resistance wire of the ironing knife 24 stops being energized.

[0067] The winding roller 23 is provided with a wire breaking mechanism, comprising a notch 27 defined along the axis of the winding roller 23. A wire breaking cylinder 28 is fixedly mounted within the winding roller 23. A wire cutting knife 29 is positioned at the extended end of the piston of the wire breaking cylinder 28, which corresponds to the notch 27. A controller controls the extension and retraction of the piston of the wire breaking cylinder 28. After the hot knife 24 melts the thread ends, and the fabric thread is still wound around the winding roller 23, the controller controls the piston of the wire breaking cylinder 28 to extend, driving the wire cutting knife 29 toward the notch 27, thereby severing the fabric thread wound around the winding roller 23. Once the fabric thread is severed, the wire cutting knife 29 retracts and returns to its original position. When the pressure sensor detects a lack of pressure on the winding roller 23, the controller controls the winding motor 25 to restart, resuming fabric transmission.

[0068] like Figure 4As shown, the end of the winding roller 23 is provided with a shaking-off device that can shake off broken fabric threads from the winding roller 23. The shaking-off device is located outside the sensing range of the pressure sensor, so it does not affect the normal sensing of the fabric thread pressure by the pressure sensor. The shaking-off device includes a shaking-off seat 30, a shaking-off shaft 31, and a partial gear 32. The shaking-off seat 30 is fixedly set at a section of the winding roller 23 away from the cutting seat 22; the shaking-off shaft 31 is slidably set on the shaking-off seat 30, and the shaking-off shaft 31 is perpendicular to the axis of the winding roller 23. A transmission tooth 33 is set on the shaking-off seat 30 along the axis direction, and both ends of the shaking-off shaft 31 extend out of the shaking-off seat 30 and are provided with a limit block 34. A spring 35 is set between the limit block 34 of the shaking-off shaft 31 close to the winding roller 23 and the shaking-off seat 30. When the spring 35 is in a natural state, the end of the shaking-off shaft 31 is pressed on the winding roller 23; the incomplete gear 32 is rotatably set on the shaking-off seat 30 and is located below the transmission tooth 33. The teeth on the incomplete gear 32 can engage with the transmission teeth 33 on the shaking-off shaft 31, and the axis of the incomplete gear 32 is perpendicular to the shaking-off shaft 31. The incomplete gear 32 is connected to the circumferential rotation power source and can rotate circumferentially. The circumferential rotation power source causes the incomplete gear 32 to rotate. When the teeth on the incomplete gear 32 rotate to engage with the transmission teeth 33 on the shaking-off shaft 31, the shaking-off shaft 31 moves away from the winding roller 23, and the spring 35 is squeezed. When the incomplete gear 32 continues to rotate so that the teeth on it disengage from the transmission teeth 33 on the shaking-off shaft 31, the spring 35 moves the shaking-off shaft 31 to reset, causing the end of the shaking-off shaft 31 to hit the winding roller 23. The winding roller 23 will shake when it is hit, and the debris and fabric line on the winding roller 23 will be shaken off, preventing the pressure sensor from being affected. At the same time, the shaking-off shaft 31 reciprocates away from and close to the winding roller 23, and there can be a period of time when it is not in contact with the winding roller 23 during the rotation of the winding roller 23. This can increase the service life of the winding roller 23 and the shaking-off shaft 31.

[0069] A junction box 36 is located below the winding roller 23. The junction box 36 is equipped with a cable duct 37, which is connected to an air pump. The air pump maintains a negative pressure in the cable duct 37, allowing the fabric threads to fall into the junction box 36 and be sucked out of the cable duct 37 to the outside of the oven 1.
