Description

Technical Field

[0001] The invention relates to the technical field of textile processing, and in particular to a denim drying device. Background Art

[0002] In the textile industry, the drying of denim is an important part of the production process. At present, the commonly used denim drying equipment usually adopts traditional heating methods, such as electric heating, steam heating, etc. However, these traditional drying equipment have obvious defects. On the one hand, they consume a lot of energy. In today's increasingly tight energy and increasing environmental protection requirements, high-energy consumption drying equipment not only increases production costs, but also does not meet the requirements of sustainable development. On the other hand, due to the uneven thickness of denim itself, commonly used drying equipment is often difficult to achieve uniform and effective drying. Thicker parts may be over-dried, resulting in poor texture, color change or even damage to the fabric; while thinner parts may not be dried in place, with residual moisture, affecting subsequent processing and quality. This uneven drying effect not only reduces the quality and yield of denim, but may also lead to a decline in customer satisfaction and bring economic losses to production companies.

DETAILED DESCRIPTION

[0030] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0032] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0034] Reference Figure 1~Figure 2 In an embodiment of the present invention, a denim drying device is provided, which is used for drying denim and includes a machine body 1, wherein the machine body 1 has a first cavity 101, and the first cavity 101 has a first hot air inlet 102, a first hot air outlet 103, a first cloth inlet 104 and a first cloth outlet 105; a first supporting roller 2 is rotatably arranged in the first cavity 101, and a second supporting roller 3 is rotatably arranged relative to the first cavity 101 and horizontally slidably arranged, the second supporting roller 3 is parallel to the rotation axis of the first supporting roller 2, and the second supporting roller 3 approaches or moves away from the first supporting roller 2 after horizontal sliding, and the denim is used to pass through the first cloth inlet 104, the surface of the first supporting roller 2, the surface of the second supporting roller 3 and the first cloth outlet 105 in sequence.

[0035] In this embodiment, the low temperature, medium temperature and high temperature mentioned in this scheme are measured to vary in the range of 60~85℃, 85~125℃ and 125~170℃ during the production process, wherein the low temperature does not refer to a temperature lower than the ambient temperature, but is only a lower temperature relative to the medium and high temperatures.

[0036] In actual operation, hot air flows into the first cavity 101 through the first hot air inlet 102, carries heat to dry the denim, and then is discharged from the first hot air outlet 103. The first support roller 2 is rotatably arranged in the first cavity 101 to support and guide the movement of the denim. The second support roller 3 can both rotate and slide horizontally relative to the first cavity 101. During operation, according to the thickness of the denim, the second support roller 3 is horizontally slid to move closer to or away from the first support roller 2. When processing thicker denim, the second support roller 3 is slid away from the first support roller 2 to provide more accommodation space for the fabric; when processing thinner denim, it is slid closer to the first support roller 2. The denim passes through the first fabric inlet 104, the surface of the first support roller 2, the surface of the second support roller 3 and the first fabric outlet 105 in sequence. When the spacing increases, the residence time of the denim in the first cavity 101 increases. For example, for thicker denim with a higher water content, increasing the spacing can give it more time to receive the drying effect of hot air and ensure that the water is fully evaporated. By adjusting the spacing between the second support roller 3 and the first support roller 2, the drying needs of denim of different thicknesses can be met, and the versatility is stronger. Accurate spacing setting allows the denim to be heated evenly, avoiding local over-drying or insufficient drying, and improving the overall drying quality. Increasing the spacing can extend the residence time of the denim in the cavity, which is particularly beneficial for fully drying thick denim with a high water content. Make more full use of heat, reduce energy waste, and reduce production costs.

[0037] Furthermore, the first supporting roller 2 and the second supporting roller 3 together constitute a first distance-adjustable supporting assembly 200, and the first distance-adjustable supporting assembly 200 is composed of several groups vertically arranged in the first cavity 101, and several first supporting rollers 2 are arranged in a transverse and vertically staggered manner, and the second supporting roller 3 in one group of first distance-adjustable supporting assemblies 200 is located on the left side of the first supporting roller 2, and the second supporting roller 3 in another adjacent group of first distance-adjustable supporting assemblies 200 is located on the right side of the first supporting roller 2.

[0038] In this embodiment, the first support rollers 2 in each group of first adjustable distance support assemblies 200 are arranged in a staggered manner in the transverse direction. For example, the first support rollers 2 in the first group are located to the left, and the first support rollers 2 in the second group are located to the right, staggered in sequence. The second support rollers 3 in each group of first adjustable distance support assemblies 200 are located on one side of the first support roller 2 in the transverse direction, and the second support rollers 3 in two adjacent groups of first adjustable distance support assemblies 200 are located on different sides of the first support roller 2. In the actual drying process, after the denim enters from the first fabric inlet 104, it passes through each group of first adjustable distance support assemblies 200 arranged vertically in sequence. Due to the staggered arrangement of the first support rollers 2 and the position setting of the second support rollers 3, the denim is conveyed in an "S" shape in a circuitous manner in the first cavity 101, which increases the travel and residence time of the denim in the first cavity 101. The denim is conveyed in an "S" shape, which prolongs the residence time in the first cavity 101 and improves the drying effect, especially for thicker denim or denim with a high water content. The staggered support rollers enable the denim to be more fully exposed to the hot air flow during transportation, so that the heat is more evenly distributed, and the uneven drying is reduced. The vertically arranged components are compact in structure, and more support rollers can be arranged in the limited first cavity 101, which improves the efficiency of space utilization. The combined effect of multiple groups of support rollers makes the transportation of denim more stable during the drying process, reducing the shaking and deviation of the fabric. The second support rollers 3 in each group of the first adjustable distance support assembly 200 can adjust the spacing, and can be accurately adjusted according to the thickness of the denim in different parts, further optimizing the drying effect.

[0039] Furthermore, the machine body 1 also has a second cavity 106, which is located on a side of the first cavity 101 away from the first cloth inlet 104. The second cavity 106 has a total cloth outlet 107, a second hot air inlet 108 and a second hot air outlet 109. The first hot air outlet 103 leads to the second cavity 106 through the second hot air inlet 108. The denim is used to pass from the first cloth outlet 105 to the second cavity 106 and be delivered from the total cloth outlet 107.

[0040] In this embodiment, in actual work, after the denim is preliminarily dried in the first cavity 101, it enters the second cavity 106 from the first fabric outlet 105. Since the hot air from the first hot air outlet 103 enters the second cavity 106 through the second hot air inlet 108, the denim is further dried and finally sent out from the total fabric outlet 107. The denim dried in the first cavity 101 may still have a slightly higher moisture content in some areas. After entering the second cavity 106, it is dried again using residual heat and supplementary hot air to ensure the overall drying effect. The hot air discharged from the first cavity 101 is introduced into the second cavity 106, which realizes the reuse of heat energy and reduces energy consumption. The denim preliminarily dried in the first cavity 101 is dried twice to ensure that the denim is completely dried and improve product quality. The heat loss is reduced, the thermal pollution to the environment is reduced, and the requirements of energy saving and environmental protection are met. Through the reuse of heat energy and a more perfect drying effect, the production cost and operating cost are reduced.

[0041] Furthermore, it also includes a third supporting roller 4 and a fourth supporting roller 5, which together constitute a second distance-adjusting supporting assembly 400. The second distance-adjusting supporting assembly 400 and the first distance-adjusting supporting assembly 200 have the same structure and placement method, and the first distance-adjusting supporting assembly 200 and the second distance-adjusting supporting assembly 400 are configured such that when the second supporting roller 3 in each group is away from the first supporting roller 2, the fourth supporting roller 5 is close to the third supporting roller 4.

[0042] In this embodiment, the intrinsic setting temperature of the second cavity 106 is lower than that of the first cavity 101. In the actual drying operation, for thicker fabrics, the strategy of extending the heating time in the first cavity 101 is adopted. For example, by increasing the distance between the first support roller 2 and the second support roller 3, the residence time of the thicker fabric in the first cavity 101 is increased, so that the fabric is fully dried by the high-temperature hot air. At the same time, the heating time in the second cavity 106 is shortened. Because the thicker fabric has been dried for a long time at high temperature in the first cavity 101, most of the moisture has been removed, and only a short supplementary drying is required in the second cavity 106 with a lower temperature to achieve the ideal drying effect. On the contrary, for thinner fabrics, the heating time in the first cavity 101 is shortened, and the distance between the first support roller 2 and the second support roller 3 is reduced, so that the fabric can pass through the first cavity 101 quickly. The heating time in the second cavity 106 is relatively prolonged to ensure the drying quality of thin fabrics. The heating time in different cavities is flexibly adjusted according to the thickness of the fabric, so as to achieve precise control of the drying process and improve the drying effect. Avoid over-drying of thinner fabrics and under-drying of thicker fabrics, save energy to the greatest extent and improve drying efficiency. Ensure that denim of different thicknesses can reach the ideal drying degree, improve the overall quality and consistency of the product. It can meet the drying requirements of denim of different thicknesses, enhance the applicability and versatility of the equipment. By reasonably allocating drying time and energy consumption, it reduces production costs and improves production efficiency.

[0043] Furthermore, the machine body 1 also has a third cavity 110 , which is located on a side of the first cavity 101 away from the second cavity 106 , and has a main cloth inlet 111 , a second cloth outlet 112 , a third hot air inlet 113 and a main hot air outlet 114 .

[0044] In this embodiment, during the production process, the denim first enters the third cavity 110 through the main fabric inlet 111, and the hot air input from the third hot air inlet 113 performs a preliminary preheating treatment on the denim, and then passes through the first cavity 101 and the second cavity 106 for drying in sequence, and finally is sent out from the second fabric outlet 112. In the third cavity 110, the low-temperature hot air preheats the denim that is about to enter the drying stage, so that its temperature rises, and prepares for the subsequent efficient drying in the first cavity 101 and the second cavity 106. The setting of the third cavity 110 provides a preheating link for the denim, which helps to improve the efficiency and quality of subsequent drying. Preheating the denim before entering the drying reduces the energy required to achieve the drying effect in the first cavity 101 and the second cavity 106, saving energy. The preheated denim is easier to achieve uniform drying in the subsequent drying process, reducing the situation of uneven drying. The entire drying process is made more continuous and complete, and the fluency and stability of production are improved. The preheating process can reduce the potential damage to the quality of the denim caused by sudden high-temperature drying, and maintain the physical properties and appearance of the fabric.

[0045] Furthermore, the inner wall of the third cavity 110 has a partition 115, which divides the third cavity 110 into an upper low-temperature cavity 116 and a lower low-temperature cavity 117. The upper low-temperature cavity 116 and the lower low-temperature cavity 117 are connected by a narrow gap, and the second hot air outlet 109 leads to the upper low-temperature cavity 116. The lower low-temperature cavity 117 is connected to the outside through the main hot air outlet 114. It also includes a fifth support roller 6 and a sixth support roller 7. The fifth support roller 6 and the sixth support roller 7 are rotatably arranged in the upper low-temperature cavity 116 and the lower low-temperature cavity 117, respectively, and the rotation axis is parallel to the first support roller 2. The denim is used to enter the third cavity 110 from the main fabric outlet 107, pass through the surfaces of the fifth support roller 6 and the sixth support roller 7 in turn, and enter the first cavity 101 through the second fabric outlet 112.

[0046] In this embodiment, in actual operation, the denim enters the third cavity 110 from the total fabric outlet 107. It first passes through the fifth support roller 6 in the upper low-temperature cavity 116, then enters the lower low-temperature cavity 117 through the narrow slit, then passes through the surface of the sixth support roller 7, and finally enters the first cavity 101 through the second fabric outlet 112. The residual heat of the denim dried in the second cavity 106 enters the upper low-temperature cavity 116 through the second hot air outlet 109, and preheats the denim that has just entered. When the denim passes through the upper low-temperature cavity 116 and the lower low-temperature cavity 117, under the guidance of the fifth support roller 6 and the sixth support roller 7, it is fully in contact with the low-temperature environment, and the temperature and humidity are further adjusted. Through the setting of the upper low-temperature cavity 116 and the lower low-temperature cavity 117, the temperature and humidity of the denim are adjusted more finely, and the drying quality is improved. The residual heat of the second cavity 106 enters the upper low-temperature cavity 116, realizing energy recycling and reducing energy consumption. The entire drying process is made more coherent and orderly, and production efficiency is improved. The separation of the upper and lower low-temperature chambers 117 and the setting of the supporting rollers ensure the stable transportation of the denim during the low-temperature adjustment process, which can better meet the drying requirements of denim of different types and thicknesses and improve the versatility of the equipment.

[0047] Furthermore, the fifth supporting roller 6 and the sixth supporting roller 7 have a first airflow channel 601 and a second airflow channel 602 inside, respectively, and the first airflow channel 601 leads to the second airflow channel 602; the roller surfaces of the fifth supporting roller 6 and the sixth supporting roller 7 have a plurality of first overflow holes 603 and second overflow holes 604 arranged circumferentially, respectively, the first overflow holes 603 are used to connect the first airflow channel 601 and the upper low-temperature chamber 116, and the second overflow holes 604 are used to connect the second airflow channel 602 and the lower low-temperature chamber 117.

[0048] In this embodiment, in actual work, for example, when the low-temperature airflow passes through the first airflow channel 601, it will overflow from the first overflow hole 603 into the upper low-temperature chamber 116; similarly, when the low-temperature airflow passes through the second airflow channel 602, it will overflow from the second overflow hole 604 into the lower low-temperature chamber 117. The low-temperature airflow provided by the outside first enters the first airflow channel 601 of the fifth support roller 6, and then a part enters the upper low-temperature chamber 116 through the first overflow hole 603, and the other part continues to flow to the second airflow channel 602, and then enters the lower low-temperature chamber 117 through the second overflow hole 604. The low-temperature airflow is uniformly released through the overflow holes, so that the temperature distribution in the upper low-temperature chamber 116 and the lower low-temperature chamber 117 is more uniform, and the temperature regulation effect on the denim is improved. When the denim is in contact with the fifth support roller 6 and the sixth support roller 7, the low-temperature hot airflow can pass through the pores of the denim, maximizing the preheating effect while not damaging the fabric, saving time and energy for subsequent drying. It avoids the damage to the fabric caused by excessive preheating temperature, ensuring that the physical properties and appearance quality of the denim are not affected.

[0049] Furthermore, it also includes a first partition member 8, which is lifted and slidably arranged in the first cavity 101, and a high-temperature cavity 801 is formed between the first partition member 8 and the inner wall of the first cavity 101. The first hot air inlet 102, the first hot air outlet 103, the first cloth inlet 104 and the first cloth outlet 105 are all connected to the high-temperature cavity 801. The first partition member 8 is configured to increase or decrease the high-temperature cavity 801 after lifting and sliding.

[0050] In this embodiment, when thicker fabrics are processed, the first partition member 8 rises and slides, shrinking the high-temperature chamber 801. This design allows the hot air flow to be more concentrated in a smaller space, thereby heating the thicker fabrics more concentratedly and quickly. After the thicker fabrics enter the first cavity 101, the reduced high-temperature chamber 801 allows the hot air flow to act more strongly on the fabrics, quickly raising the temperature of the fabrics, accelerating the evaporation of water, and achieving rapid drying. Shrinking the high-temperature chamber 801 allows the heat to act more concentratedly on the thicker fabrics, improving the heating efficiency and shortening the drying time. A more concentrated heat supply helps ensure that all parts of the thicker fabrics are fully heated and reduces uneven drying. Rapid and uniform drying helps maintain the physical properties and quality of the fabrics and reduces the quality degradation caused by excessive drying time. For thinner fabrics, more airflow space can be provided to prevent the fabrics from being overheated due to concentrated high temperatures.

[0051] Furthermore, it also includes a second partition member 9, which is raised and lowered and slidably arranged in the second cavity 106, and a medium-temperature cavity 901 is formed between the second partition member 9 and the inner wall of the second cavity 106. The first cloth outlet 105, the total cloth outlet 107, the second hot air inlet 108 and the second hot air outlet 109 are all connected to the medium-temperature cavity 901. The second partition member 9 is configured to increase or decrease the medium-temperature cavity 901 after being raised and lowered and slid.

[0052] In this embodiment, in actual operation, when processing denim with a low moisture content, the second baffle member 9 rises and slides to reduce the medium temperature chamber 901, so that the hot air flow is more concentrated and the final drying process is carried out efficiently. When processing denim with a high moisture content, the second baffle member 9 slides downward to enlarge the medium temperature chamber 901, providing more sufficient heat and time to dry the cloth. In addition, when the high temperature chamber 801 is reduced, the residence time of the airflow in the high temperature chamber 801 is reduced. This means that more hot air can flow quickly to the medium temperature chamber 901, thereby increasing the hot air temperature in the medium temperature chamber 901. For example, the hot air that originally stayed in the high temperature chamber 801 for a long time quickly enters the medium temperature chamber 901 due to the reduction of the high temperature chamber 801, increasing the heat supply of the medium temperature chamber 901. By changing the size of the medium temperature chamber 901 through the second baffle member 9, the temperature of the medium temperature chamber 901 can be accurately controlled to meet the requirements of different working conditions. Reasonably adjust the space of the medium temperature chamber 901 to avoid energy waste and improve the overall energy utilization efficiency. Ensure that denim with different moisture contents achieves ideal drying effects and reduces drying defects. Reduce the high temperature chamber 801 to reduce the airflow retention time, increase the hot air temperature of the medium temperature chamber 901, and improve drying efficiency.

[0053] Furthermore, the first partition member 8 has a first guide bevel 803 and a second guide bevel 802, and the two adjacent second supporting rollers 3 have a first sliding part 201 and a second sliding part 301 respectively, and the first sliding part 201 and the second sliding part 301 are respectively slidably arranged in the first guide bevel 803 and the second guide bevel 802, and the first partition member 8 is configured to drive the first sliding part 201 and the second sliding part 301 to move closer to or away from each other after lifting and sliding; the second partition member 9 has a third guide bevel 903 and a fourth guide bevel 902, and the two adjacent fourth supporting rollers 5 have a third sliding part 401 and a fourth sliding part 502 respectively, and the third sliding part 401 and the fourth sliding part 502 are respectively slidably arranged in the third guide bevel 903 and the fourth guide bevel 902, and the second partition member 9 is configured to drive the third sliding part 401 and the fourth sliding part 502 to move closer to or away from each other after lifting and sliding.

[0054] In this embodiment, in actual operation, when the first partition member 8 is lifted and slid, the first partition member 8 rises, and due to the inclined setting of the guide chute, the first sliding part 201 and the second sliding part 301 are driven to approach each other, thereby reducing the distance between the first supporting roller 2 and the second supporting roller 3. On the contrary, when the first partition member 8 is lowered, the first sliding part 201 and the second sliding part 301 are driven to move away from each other, thereby increasing the distance between the first supporting roller 2 and the second supporting roller 3. Similarly, the second partition member 9 has a third guide chute 903 and a fourth guide chute 902, and the third sliding part 401 of the third supporting roller 4 and the fourth sliding part 502 of the fourth supporting roller 5 are slidably arranged in the third guide chute 903 and the fourth guide chute 902, respectively. When the second partition member 9 is lifted and slid, the third sliding part 401 and the fourth sliding part 502 are driven to approach or move away from each other accordingly, thereby adjusting the distance between the third supporting roller 4 and the fourth supporting roller 5. When thinner denim needs to be processed, the first partition member 8 and the second partition member 9 rise, driving the corresponding supporting roller sliding parts to approach each other and reduce the distance between the supporting rollers; when thicker denim needs to be processed, the partition member descends, driving the sliding parts to move away from each other and increase the distance between the supporting rollers. The lifting and lowering of the partition member and the adjustment of the distance between the supporting rollers are linked, which simplifies the operation and improves the adjustment efficiency. The device can flexibly respond to the drying needs of denim of various thicknesses and enhance the versatility of the equipment.
