Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric processing technology, and in particular to a low-temperature dryer for processing nylon fabrics. Background Technology
[0002] Nylon refers to polyamide fiber, a type of synthetic fiber linked by amide bonds. Nylon fabrics have become an important material in the modern textile industry due to their high abrasion resistance, elasticity, and multifunctionality.
[0003] Because nylon fabrics have poor heat resistance, they need to be dried at low temperatures during processing to reduce batch color differences and quality instability caused by temperature fluctuations.
[0004] However, existing dryers typically have an inlet for the fabric to be dried and an outlet for the fabric to exit on the left and right sides of the machine body, respectively. The fabric is then conveyed in a straight line inside the machine by guide rollers, and warm air is blown onto the fabric by a fan inside the machine to achieve the drying effect. However, this drying method can easily lead to uneven heating of the side of the fabric that is not facing the fan during the drying process, thus affecting the drying effect and efficiency. Therefore, a low-temperature dryer for nylon fabric processing is proposed to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] like Figure 1-5 As shown, the present invention proposes a low-temperature dryer for processing nylon fabric, including a drying chamber 1 and a door 2 hinged to the front of the drying chamber 1. The drying chamber 1 is provided with an air supply component 3 for drying fabric.
[0031] The drying chamber 1 is equipped with a fabric guiding and conveying guide 4.
[0032] In this invention, the air supply component 3 and the guide component 4 on the drying chamber 1 can extend the running path of the fabric in the drying chamber 1, and at the same time, hot air can be blown evenly on both sides of the fabric for drying.
[0033] It should be noted that the drying chamber 1 has guide holes on one side and the other side to facilitate the entry and exit of the drying fabric. The drying chamber 1 is also connected to an exhaust pipe at the top to discharge the water vapor generated by the fabric during the drying process.
[0034] In an optional embodiment, the air supply component 3 includes a ventilation chamber 31 fixedly connected to the upper end of the drying chamber 1. A support cylinder 32 communicating with the upper end of the ventilation chamber 31 is fixedly connected to it. A fan 34 is fixedly installed on the inner wall of the support cylinder 32. A set of air guide chambers 36 are fixedly connected to the inner side wall of the drying chamber 1. A ventilation pipe 35 is connected to the ventilation chamber 31, with one end penetrating the drying chamber 1 and communicating with the air guide chamber 36. Several air outlets 37 are opened on the air guide chamber 36. A heating pipe 38 is fixedly installed on the inner side of the ventilation chamber 31.
[0035] In this embodiment, the vertical plate 42 and the two sets of guide rollers 44 inside the drying chamber 1 can increase the drying path of the fabric in the drying chamber 1. The air guide chambers 36 on both sides of the inner wall of the drying chamber 1 can blow hot air evenly onto the fabric guided by the guide rollers 44, and both sides of the fabric can be heated and dried to improve the drying effect of the fabric.
[0036] It should be noted that a dustproof net 33 is fixedly connected to the upper end of the support cylinder 32. The dustproof net 33 on the support cylinder 32 removes dust from the air inlet of the fan 34. The air guide chambers 36 are symmetrically distributed on the inner wall of the drying chamber 1, so that the air guide chambers 36 on both sides of the inner wall of the drying chamber 1 are symmetrically staggered from one above the other, so that the two air guide chambers 36 can blow hot air evenly into the drying chamber 1.
[0037] In an optional embodiment, the guide member 4 includes two vertical plates 42 symmetrically fixedly connected between the top wall and the bottom wall of the drying chamber 1. Two sets of guide rollers 44 are rotatably connected between the vertical plates 42 and the inner side of the drying chamber 1. Each vertical plate 42 is rotatably connected to the inner side of the drying chamber 1 and a drive roller 43 is rotatably connected to the inner side of the drying chamber 1. Each vertical plate 42 is rotatably connected to the inner side of the drying chamber 1 and a squeezing roller 45 that is in contact with the drive roller 43 is rotatably connected to the inner side of the drying chamber 1. Each vertical plate 42 is rotatably connected to the inner side of the drying chamber 1 and two water guide plates 41 are fixedly connected between the two vertical plates 42 and the inner side of the drying chamber 1. The two water guide plates 41 are respectively located between each set of guide rollers 44. Two drive motors 410 are fixedly installed on the back of the drying chamber 1, and the output shafts of the two drive motors 410 are respectively fixedly connected to one end of the two drive rollers 43.
[0038] An elastic element for supporting the extrusion roller 45 is provided between the vertical plate 42 and the inner wall of the drying chamber 1.
[0039] In this embodiment, during the drying process, the extrusion roller 45, which works in conjunction with the bonding drive roller 43, can squeeze out water from the fabric entering and exiting the drying chamber 1, thereby reducing the moisture content of the fabric during the drying process and further improving the drying effect.
[0040] It should be noted that the two sets of guide rollers 44 are symmetrically distributed between the two vertical plates 42 and the inner side of the drying chamber 1, so that the two sets of guide rollers 44 are symmetrically distributed one above the other, and each set of guide rollers 44 is symmetrically distributed up and down to guide and convey the fabric into the drying chamber 1.
[0041] The orientation of the drive roller 43 corresponds to the orientation of the guide hole on the drying chamber 1.
[0042] The water guide plate 41 is inclined and is a trapezoidal shape with a high center and low sides. Both sides of the water guide plate 41 are raised. A drain hole 412 is provided on the back of the drying chamber 1 at the inclined part of the water guide plate 41, so that the water guide plate 41 can block the water dripping during the fabric conveying process and discharge it out of the drying chamber 1 through the drain hole 412.
[0043] Meanwhile, the top water guide plate 41 can block the water flow when the top extrusion roller 45 extrudes the fabric, while the top height of the left air guide chamber 36 is lower than the top water guide plate 41, so as to prevent the hot air blown by the left air guide chamber 36 from contacting the water flow when the top extrusion roller 45 extrudes the fabric.
[0044] In an optional embodiment, the elastic element includes a support block 49. The vertical plate 42 has a mounting hole 46 at one end near the extrusion roller 45. The inner wall of the drying chamber 1 has a mounting groove 48 corresponding to the orientation of the mounting hole 46. The support blocks 49 are slidably connected in the mounting hole 46 and the mounting groove 48 respectively, and there are four support blocks 49. The two extrusion rollers 45 are rotatably connected between the two support blocks 49 respectively. Springs 47 are fixedly connected to the inner side of the mounting hole 46 and the mounting groove 48, and the springs 47 are fixedly connected to the support blocks 49.
[0045] In this embodiment, the spring 47 located between the support block 49 and the mounting hole 46 and between the support block 49 and the mounting groove 48 can elastically support the extrusion roller 45 between the two support blocks 49, so that the elastically supported extrusion roller 45 can fit against the drive roller 43 to extrude the conveyed fabric.
[0046] It should be noted that the spring 47 located in the support block 49 and the mounting hole 46, as well as the support block 49 and the mounting groove 48, is in a compressed state. The elastic force generated by the spring 47 in the compressed state to reset can push the support block 49 to drive the extrusion roller 45 to fit against the drive roller 43.
[0047] In an optional embodiment, a shaking element 5 is provided on the back of the drying chamber 1 to shake the fabric conveyed by the drive roller 43 and the guide roller 44; the shaking element 5 includes a rotating motor 51 fixedly connected to the back of the drying chamber 1, a drive plate 54 slidably connected to the back of the drying chamber 1, three connecting rods 55 fixedly connected to the side of the drive plate 54 near the drying chamber 1, one end of which penetrates the drying chamber 1, a shaking plate 56 fixedly connected to the end of the connecting rod 55 penetrating the drying chamber 1, a turntable 52 fixedly connected to the output shaft of the rotating motor 51, and a connecting rod 53 rotatably connected at one end to the drive plate 54 at the eccentric part of the turntable 52.
[0048] In this embodiment, the rotating motor 51, when driving the turntable 52 to rotate, can drive the drive plate 54 to vibrate through the connecting rod 53, thereby causing the connecting rod 55 on the drive plate 54 and the vibrating plate 56 in the drying chamber 1 to vibrate, thus beating the fabric during the drying process and further reducing the moisture content of the fabric during the drying process.
[0049] It should be noted that a rectangular hole 411 for sliding the connecting rod 55 is provided on the back of the drying chamber 1. The three shaking plates 56 are evenly distributed from bottom to top and are staggered with the two water guide plates 41. This allows the water flow from the fabric during the shaking and patting process of the three shaking plates 56 to be blocked and guided by the water guide plates 41. At the same time, the inner bottom wall of the drying chamber 1 is concave in the middle and inclined on both sides, so that the inner bottom wall of the drying chamber 1 can easily guide the water flow from the bottom shaking plates 56 through the rectangular hole 411.
[0050] A temperature sensor (not shown in the figure) is installed on the inner wall of the drying chamber 1 to monitor the temperature inside the drying chamber 1. A controller is installed on the chamber door 2, and the controller is electrically connected to the temperature sensor. By monitoring the temperature inside the drying chamber 1 through the controller and the temperature sensor, the heating tube 38 is controlled at 40~60℃ during the heating process to achieve low-temperature drying of nylon fabric. At the same time, the control method of this utility model is automatic control through the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. This utility model is mainly used to protect the mechanical structure, so the control method and circuit connection and other technical means will not be described in detail.
[0051] The working principle in the above embodiments is as follows:
[0052] After the fabric enters the drying chamber 1 from one side, the fabric end is pulled through the top drive roller 43 and guide roller 44, and wound around the two sets of guide rollers 44. Finally, it passes through the bottom drive roller 43 and squeeze roller 45 and is sent out of the drying chamber 1.
[0053] Then, the fan 34 and heating pipe 38 are started to deliver hot air into the air guide chamber 36 through the ventilation pipe 35. The hot air is then blown out through several air outlets 37 on the air guide chamber 36 to evenly blow hot air onto both sides of the fabric for drying. During the drying process, the drive motor 410 can be started to drive the drive roller 43 to rotate and convey the fabric during the drying process. The fabric that is subsequently conveyed into the drying chamber 1 can be squeezed by the elastically supported squeezing roller 45 to squeeze out some of the water contained in the fabric. At the same time, the rotating motor 51 is started to drive the turntable 52 to rotate. After the connecting rod 53 drives the drive plate 54 to shake, it drives the connecting rod 55 on the drive plate 54 and the shaking plate 56 in the drying chamber 1 to shake and beat the fabric during the drying process to further reduce the moisture content of the fabric during the drying process, while also drying with the blown hot air.
[0054] The water squeezed by the extrusion roller 45 and the water flow patted by the shaking plate 56 during the shaking process can be discharged from the drying chamber 1 through the water guide plate 41 in conjunction with the drainage hole 412 and the rectangular hole 411 on the inner bottom wall of the drying chamber 1.
[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
