Description

Technical Field

[0001] The present invention relates to the technical field of textile drying equipment, and in particular to a drying equipment for textile fabric production. Background Art

[0002] Drying is a crucial step in the textile production process, directly impacting fabric quality, the efficiency of subsequent processing, and the stability of the finished product. When wet textiles are not dried thoroughly and evenly, they are prone to mold growth, resulting in discoloration and unpleasant odors. Furthermore, dimensional deviations can occur during subsequent processing steps like cutting, printing, and dyeing, seriously impacting the quality of the final product.

[0003] Currently, drying equipment widely used in the textile industry mostly uses drying drums to heat and dry fabrics. This type of equipment typically features multiple drying drums mounted at regular intervals on a frame, with the fabric wound around each drum in sequence. During drying, heat is generated by a heat source within the drum (such as steam or electric heating). This heat is transferred to the drum wall, heating the fabric in contact with the drum wall and evaporating moisture from the fabric, achieving the desired drying effect.

[0004] However, traditional drying equipment has certain limitations in practical application. Traditional equipment usually arranges multiple drying drums closely together. However, since textiles are dried continuously, the steam generated during the drying process will reattach to the textiles located above, causing the humidity of the textiles to rise slightly after the initial drying, which in turn slows the drying speed. However, if the distance between the drying drums is increased to avoid this, the slower rotation speed of the drying drums will cause the temperature of the textiles suspended between adjacent drying drums to drop. This will cause the textiles to repeatedly heat up and cool down, which is extremely detrimental to the overall structure of the textiles. Summary of the Invention

[0005] To overcome the above-mentioned defects, an embodiment of the present invention provides a drying device for textile fabric production, which solves the technical problem in the prior art that the moisture content of the fabric may rise or the temperature may change repeatedly due to the problem of the spacing between the drying cylinders in the traditional drying equipment.

[0025] like Figure 1 and Figure 2 As shown, it shows a drying device for producing textile fabrics 3 in one embodiment of the present invention, which is used to dry textile fabrics 3 containing moisture. The drying device as a whole includes a frame 1, a plurality of drying drums 2, and a bracket 4 arranged on the drying drum 2. Specifically, the plurality of drying drums 2 are arranged on the frame 1 at a certain interval, and the textile fabrics 3 are wound around these drying drums 2 in sequence. The textile fabrics 3 are wound around the drying drum 2 in an S shape, and the drying drum 2 is used to heat and dry the textile fabrics 3. The bracket 4 is detachably arranged on the drying drum 2. It should be noted that the bracket 4 can also be directly mounted on the frame 1. An external heating plate 5 is mounted on the bracket 4. A heating coil 6 is arranged inside the external heating plate 5, and the heating coil 6 is interconnected with the interior of the drying drum 2. This design allows the hot air inside the drying drum 2 to enter the heating coil 6 after heating the drying drum 2, and the external heating plate 5 is specifically used to heat the textile fabrics 3 between two adjacent drying drums 2.

[0026] For example, Figure 1 As shown, during operation, when the device is started, the heat source inside the drying drum 2 begins to operate. The generated hot air first heats the drying drum 2 itself, causing the wall temperature of the drying drum 2 to increase. When the textile fabric 3 is wrapped around the drying drum 2, the heat from the wall is transferred to the fabric, heating and drying the fabric. Simultaneously, the hot air inside the drying drum 2 only enters the heating coil 6 after filling the drying drum 2, which ensures that the heat at all locations on the wall of the drying drum 2 is roughly uniform. It should be noted that a valve is provided at the exhaust port 220 of the drying drum 2. When the air pressure inside the drying drum 2 increases to a preset pressure value, the valve automatically opens, allowing the hot air to enter the heating coil 6. The heating coil 6 then transfers the heat to the external heating plate 5, which then heats the textile fabric 3 suspended between two adjacent drying drums 2. In this way, the fabric is continuously heated throughout the entire transmission process, avoiding the problem of fabric temperature drop between adjacent drying drums 2 in traditional equipment.

[0027] In summary, on the one hand, heating the fabric between adjacent drying drums 2 via the external heating plate 5 effectively prevents the fabric from cooling during transport, avoiding repeated heating and cooling of the fabric, and protecting the overall structure of the textile fabric 3. On the other hand, since the heating coil 6 is connected to the interior of the drying drum 2, it fully utilizes the waste heat within the drying drum 2, improving energy efficiency, speeding up the drying of the fabric, ensuring uniform drying of the fabric, and reducing problems such as mold growth, discoloration, odor, and subsequent dimensional deviation caused by insufficient drying.

[0028] In some examples, the drying drum 2 has an air inlet 230 for introducing hot air and an exhaust port 220 for exhausting hot air. The air inlet 230 and the exhaust port 220 are both located at the center of the two end faces of the drying drum 2, which makes it easy to connect pipes to the air inlet 230 and the exhaust port 220. Specifically, the drying drum 2 includes a heat-conducting cylinder 21, a fixed end cover 22, and a movable end cover 23. The fixed end cover 22 is fixedly arranged at one end of the heat-conducting cylinder 21. The fixed end cover 22 is snapped onto the end of the heat-conducting cylinder 21 to close one end of the heat-conducting cylinder 21. The end of the fixed end cover 22 away from the heat-conducting cylinder 21 is rotatably connected to the frame 1. The position of the bracket 4 close to the fixed end cover 22 is directly sleeved on the fixed end cover 22, so that the bracket 4 will not rotate with the fixed end cover 22, and the exhaust port 220 is located on the first shaft tube of the fixed end cover 22. It should also be noted that a sprocket is fixedly provided on the outside of the fixed end cover 22. The sprocket is a driven sprocket. A reduction motor is provided on the frame 1. A driving sprocket is provided at the output end of the reduction motor. The chain is wound around the driven sprocket and the driving sprocket of each drying cylinder 2 in sequence. In this way, when the reduction motor is driven, it can drive several drying cylinders 2 to rotate synchronously to ensure that the textile fabric 3 will not be damaged by excessive pulling during the drying process.

[0029] Secondly, when the fixed end cover 22 rotates, it can drive the heat-conducting cylinder 21 to rotate together, so that the heat-conducting cylinder 21 can be used as a power source for the movement of the textile fabric 3, driving the textile fabric 3 to continue drying. The movable end cover 23 is detachably arranged at the other end of the heat-conducting cylinder 21. Specifically, the movable end cover 23 is also directly fastened to the heat-conducting cylinder 21, but a sealing ring is provided at the connection between the two for sealing. The reason for adopting a detachable connection is that the interior of the heat-conducting cylinder 21 needs to be cleaned and removed after each production period. In addition, the end of the movable end cover 23 away from the heat-conducting cylinder 21 is fixedly connected to the frame 1 through a second shaft tube. The movable end cover 23 is mainly used to support the heat-conducting cylinder 21 and to close the other end of the heat-conducting cylinder 21. The air inlet 230 is opened on the second shaft tube of the movable end cover 23. The position of the bracket 4 near the movable end cover 23 is connected to the movable end cover 23 through a flange to ensure that the bracket 4 does not rotate with the heat-conducting cylinder 21.

[0030] For example, Figure 1 and Figure 3 As shown, during operation, external hot air enters the heat-conducting cylinder 21 through the air inlet 230. The hot air flows inside the heat-conducting cylinder 21, transferring heat to the heat-conducting cylinder 21, causing the temperature of the heat-conducting cylinder 21 to rise, thereby heating and drying the textile fabric 3 on its surface. During the flow of hot air, the fixed end cover 22 rotates with the rotation of the heat-conducting cylinder 21, ensuring the normal operation of the heat-conducting cylinder 21. At the same time, the hot air after heat exchange is discharged through the exhaust port 220. When the interior of the drying cylinder 2 needs to be inspected or cleaned, the movable end cover 23 can be removed from the heat-conducting cylinder 21. Since the movable end cover 23 is slidably connected to the heat-conducting cylinder 21, the disassembly process is more convenient.

[0031] The fixed end cap 22, rotatably connected to the frame 1, drives the heat-conducting cylinder 21 to rotate smoothly, ensuring continuous transfer of textile fabric 3 and a smooth drying process. The removable end cap 23 facilitates maintenance and cleaning of the interior of the drying drum 2, helping to maintain it in good working condition and extending the life of the equipment. The air inlet 230 and exhaust port 220 ensure smooth flow of hot air within the drying drum 2, improving heat exchange efficiency and, in turn, enhancing the drying effect of the fabric.

[0032] In some examples, the bracket 4 includes two side rods 41, which are respectively arranged at the two ends of the heat-conducting cylinder 21, wherein one end of the side rod 41 close to the fixed end cover 22 is sleeved with the fixed end cover 22, and the other end of the side rod 41 close to the movable end cover 23 is fixedly connected to the movable end cover 23. The external heating plate 5 is hingedly arranged between the two side rods 41, and the external heating plate 5 is located outside the heat-conducting cylinder 21. It should be noted that the two side rods 41 can be adjusted in position according to the winding path of the textile fabric 3 to meet the winding requirements of the textile fabric 3 and ensure that the external heating plate 5 can contact the suspended textile fabric 3 without excessively pulling the textile fabric 3.

[0033] For example, Figure 3 and Figure 4As shown, during the operation of the equipment, since one side rod frame 41 is sleeved with the fixed end cover 22, when the fixed end cover 22 drives the heat-conducting cylinder 21 to rotate, the side rod frame 41 sleeved with the fixed end cover 22 will not rotate with the fixed end cover 22, and the other side rod frame 41 fixedly connected to the movable end cover 23 will also remain stationary, so that the side rod frame 41 can stably support the external heating plate 5. The external heating plate 5 is hinged between the two side rod frames 41 and can adjust its angle according to actual needs to ensure that it can accurately heat the textile fabric 3 between two adjacent drying cylinders 2. In fact, the external heating plate 5 has a slight pushing effect on the textile fabric 3 it contacts, which can make the textile fabric 3 fit more closely to the external heating plate 5, achieving a smooth ironing effect.

[0034] The side bar brackets 41 provide stable support for the external heating plate 5, allowing it to be securely mounted in the proper position and ensuring smooth external heating. The side bar brackets 41 accommodate the rotation of the heat-conducting cylinder 21, ensuring the overall stability of the bracket 4. Furthermore, the angle of the external heating plate 5 can be flexibly adjusted, accommodating not only different winding configurations for the textile fabric 3 but also fabrics of varying thicknesses and types, thus enhancing the device's applicability.

[0035] In some examples, a deflection correction plate 42 is provided at one end of the side bar frame 41 away from the heat-conducting cylinder 21. The deflection correction plates 42 on the two side bar frames 41 work together to correct the deflection of the textile fabric 3. Specifically, the deflection correction plates 42 and the side bar frames 41 are an integral structure, and it can be understood that the deflection correction plates 42 are a separate portion of the side bar frame 41 that extends outward.

[0036] For example, Figure 1 and Figure 3 As shown, it is understood that due to the large spacing between adjacent drying drums 2 in this device, the textile fabric 3 may deviate slightly during the drying process. When this occurs during transport, the edge of the fabric 3 contacts the deflection-correcting plate 42, which exerts a lateral force on the fabric, gradually returning it to the correct transport path. Since the two deflection-correcting plates 42 are positioned on either side of the fabric, they can restrict and guide the fabric from two directions, ensuring that the fabric is always transported along the intended path.

[0037] This effectively prevents uneven drying of the textile fabric 3 due to deviation during the drying process, ensuring that all parts of the fabric are adequately heated and dried. It also avoids damage caused by friction between the fabric and other parts of the equipment due to deviation, reduces fabric waste, and improves production quality and efficiency.

[0038] In some examples, the external heating plate 5 includes a strip-shaped seat 51 and a cover plate 53. The strip-shaped seat 51 has an interior installation space 52, and the heating coil 6 is disposed within the installation space 52. The strip-shaped seat 51 has a length equal to that of the heat-conducting cylinder 21. The cover plate 53 is detachably mounted on the strip-shaped seat 51 to cover the installation space 52. The cover plate 53 has a plurality of heat dissipation holes 510 disposed at intervals therebetween. These heat dissipation holes 510 are used to transfer heat from the heating coil 6 to the textile fabric 3.

[0039] It should be noted that there are two ways to set up the external heating plate 5. The first is that the strip seat 51 itself has poor thermal conductivity, while the cover plate 53 has good thermal conductivity. In this way, the cover plate 53 is selected to directly contact the textile fabric 3, so that heat can be discharged from the heat dissipation holes 510 on the cover plate 53 to dry the textile fabric 3. In addition, it is understandable that although the panel and the strip seat 51 are detachably connected and can be connected by bolts or snap-fitting, it is necessary to ensure that the surface of the cover plate 53 is smooth. The second is that the strip seat 51 itself also has good thermal conductivity, so that part of the heat in the heating coil 6 can be dissipated outward through the strip seat 51, which can ensure that the adjacent and drying drums 2 are in a higher temperature environment and reduce heat loss from the textile fabric 3.

[0040] Secondly, it should be emphasized that the heating gas inside the drying drum 2 is steam. Conventional drying drums 2 directly input steam of appropriate temperature into the drying drum 2, filling the entire drying drum 2 with steam, then using the steam to heat the drying drum 2, and then replenishing steam to maintain a positive pressure state in the drying drum 2. When the steam condenses and becomes condensed water, it is discharged. This results in the drying drum 2 being in a high pressure state for a long time when drying the textile fabric 3. After drying a section of textile fabric 3, the condensed water must be discharged first, resulting in a long downtime and the drying drum 2 needs to undergo a short heating and cooling process. However, the steam in the drying drum 2 of the present device is flowing. The steam heats the drying drum 2 as it flows from the air inlet 230 to the outlet. Therefore, less condensed water is generated in the drying drum 2 than in conventional drying drums 2. Moreover, the spacing between two adjacent drying drums 2 arranged longitudinally in the present application is larger. Therefore, when the textile fabric 3 is wound around, it will not contact the bottom of the drying drum 2 too much. This area is the area where condensed water accumulates. Therefore, there will be no uneven heating and cooling areas on the drying drum 2, which is conducive to drying the textile fabric 3.

[0041] For example, Figure 5As shown, specifically, during operation, the heating coil 6 is heated by the hot air introduced into the drying drum 2 in the installation space 52, and the generated heat is dissipated through the heat dissipation holes 510 on the cover plate 53, directly acting on the textile fabric 3 between two adjacent drying drums 2, heating and drying the fabric. When the heating coil 6 needs to be repaired or replaced, the cover plate 53 can be removed from the strip seat 51, which is very convenient to operate. The length of the strip seat 51 is the same as that of the heat-conducting cylinder 21, which can ensure that the heating range of the fabric by the external heating plate 5 matches the heating range of the drying drum 2, ensuring that the fabric is evenly heated. The detachable cover plate 53 facilitates the maintenance and inspection of the heating coil 6 and reduces the maintenance cost of the equipment. The provision of the heat dissipation holes 510 allows heat to be concentrated and evenly transferred to the fabric, improving the heating efficiency and further ensuring the drying effect of the fabric.

[0042] In some examples, the drying apparatus further includes an annular nozzle 8 and a turntable 10. The annular nozzle 8 is fixedly mounted on a movable end cap 23, located within the heat-conducting cylinder 21 and concentrically arranged with the movable end cap 23. A plurality of air nozzles 9 are circumferentially spaced apart on the annular nozzle 8. A turntable 10 is rotatably mounted on the movable end cap 23 and is equipped with a plurality of circumferentially arranged fan blades 11. The air nozzles 9 are capable of spraying air toward the fan blades 11, thereby driving the fan blades 11 and the turntable 10 to rotate. It should be noted that a turntable 10 and fan blades 11 are also provided on the end face of the fixed end cover 22 close to the heat-conducting cylinder 21, but an annular nozzle 8 is not provided. The turntable 10 and fan blades 11 on the fixed end cover 22 can rotate along with the fixed end cover 22. The fan blades 11 on the fixed end cover 22 and the annular nozzle 8 blow the fan blades 11 in opposite directions, thereby increasing the turbulence of the steam in the drying cylinder 2 in turn. This not only allows the steam just entering to be fully and quickly mixed with the steam in the drying cylinder 2, but also ensures that the temperature of the air inlet 230 of the drying cylinder 2 is almost the same as the temperature of the exhaust port 220. Therefore, the internal pressure of the drying cylinder 2 of this device is much lower than the pressure inside the traditional drying cylinder 2, and the drying effect on the wall of the drying cylinder 2 is the same at all positions. Moreover, if the inside of the traditional drying tube is partially rusted due to corrosion by condensed water and steam, the positive pressure state of the drying cylinder 2 will cause the rusted positions to rupture, and in severe cases, an explosion may occur.

[0043] For example, Figure 6 and Figure 7 As shown, when hot air enters the heat-conducting cylinder 21 through the air inlet 230, some of the hot air enters the annular nozzle 8 and is then ejected through the air nozzle 9. The ejected airflow acts on the fan blades 11, driving them to rotate, which in turn causes the turntable 10 to rotate. The rotation of the turntable 10 creates airflow disturbances within the heat-conducting cylinder 21, making the hot air more evenly distributed within the heat-conducting cylinder 21.

[0044] The air nozzle 9 drives the turntable 10 to rotate, utilizing the kinetic energy of the hot air. This eliminates the need for an additional power unit and saves energy. The airflow disturbance created by the rotation of the turntable 10 evenly distributes the hot air within the heat-conducting cylinder 21, preventing localized overheating or underheating. This ensures uniform heating of the fabric by the heat-conducting cylinder 21 and further improves the drying quality of the fabric.

[0045] In some examples, an air passage 1001 is provided in the middle of the turntable 10, and the air passage 1001 is connected to the air inlet 230. A spoiler 13 is provided in the air passage 1001, and the function of the spoiler 13 is to disturb the hot air entering the interior of the heat-conducting cylinder 21. It should be noted that a spoiler 13 is also provided at the central circular hole of the fan blade 11. Because the spoiler 13 installed at the air passage 1001 is stationary, while the spoiler 13 at the circular hole of the fan blade 11 can rotate with the turntable 10 and the fan blade 11, the provision of two spoilers 13 can increase the disturbing effect on the airflow, and also slightly block the airflow entering the drying cylinder 2, so that part of the gas can enter the diverter cover 12, thereby increasing the gas pressure in the air inlet pipe 82.

[0046] For example, Figure 7 and Figure 8 As shown, when hot air enters the air passage 1001 from the air inlet 230, it collides with the spoiler 13. The spoiler 13 changes the flow direction of the hot air, causing the hot air to form turbulent airflow within the air passage 1001. After this turbulent airflow enters the interior of the heat-conducting cylinder 21, it further enhances the mixing and flow of the hot air, making the hot air more evenly distributed within the heat-conducting cylinder 21. The spoiler 13's disturbing effect on the hot air further improves the uniformity of the hot air within the heat-conducting cylinder 21, avoiding stratification or local stagnation of the hot air during transmission, thereby ensuring temperature consistency across all parts of the heat-conducting cylinder 21, ensuring that the textile fabric 3 is evenly heated and dried, and improving the drying effect.

[0047] In some examples, the annular nozzle 8 includes an annular air duct 81, an air inlet pipe 82, and a diverter cover 12. The diverter cover 12 can enclose an air storage chamber with the inner wall of the air passage 1001 for supplying air to the air inlet pipe 82. The diverter cover 12 is used to receive the airflow from the air inlet 230 and allow the airflow to enter the air inlet pipe 82. The annular air duct 81 is fixedly mounted on the movable end cover 23, and a plurality of air nozzles 9 are disposed on the annular air duct 81. One end of the air inlet pipe 82 is disposed on the annular air duct 81, and the other end is connected to the air passage 1001, and is used to supply part of the hot air in the air passage 1001 to the annular air duct 81. The diverter cover 12 is disposed on the inner wall of the air passage 1001, and the air inlet pipe 82 is connected to the diverter cover 12. The diverter cover 12 has an opening, and the opening faces the air inlet 230.

[0048] For example, Figure 7 and Figure 8 As shown, when hot air enters the air passage 1001 from the air inlet 230, under the guidance of the diverter cover 12, part of the hot air will enter the annular air duct 81 through the air inlet pipe 82, and then be ejected through the air nozzle 9 to drive the fan blades 11 to rotate. The opening of the diverter cover 12 faces the air inlet 230, which can collect hot air more effectively and ensure that the amount of hot air entering the annular air duct 81 is stable. The diverter cover 12 can reasonably distribute the hot air in the air passage 1001, ensuring that there is enough hot air entering the annular air duct 81, and ensuring that the air nozzle 9 can continuously and stably drive the fan blades 11 to rotate. The air inlet pipe 82 connects the air passage 1001 with the annular air duct 81, realizing the rational use of hot air and improving the utilization rate of energy. The annular air duct 81 and the air nozzle 9 ensure that the airflow can act evenly on the fan blades 11, making the turntable 10 rotate more smoothly.

[0049] In some examples, the drying apparatus further includes a hot air inlet pipe 15 and a three-way valve 7. The hot air inlet pipe 15 extends through the movable end cap 23 and communicates with the air inlet 230. The three-way valve 7 has a first port connected to the hot air inlet pipe 15, a second port connected to an external hot air source, and a third port connected via a hose to the exhaust end of the heating coil 6. The three-way valve 7 is capable of mixing the cooled hot air from the heating coil 6 with the hot air from the hot air source and then delivering the resultant mixture to the hot air inlet pipe 15. Temperature monitors are provided inside the drying drum 2 and at the air inlet 230 to monitor the temperature of the mixed steam.

[0050] For example, Figure 4 As shown, during operation, hot air from an external heat source enters through the second port of three-way valve 7. Simultaneously, hot air cooled after heat exchange in heating coil 6 enters the third port of three-way valve 7 through a hose. Within three-way valve 7, these two streams of hot air mix together before entering hot air input pipe 15 through the first port and ultimately entering the interior of drying drum 2 through air inlet 230. The cooled hot air in heating coil 6 is recycled by three-way valve 7 and mixed with the hot air from the external heat source before reentering drying drum 2, improving energy utilization and reducing energy consumption. Furthermore, the temperature of the mixed hot air is more stable, preventing the impact of temperature fluctuations from a single hot air source on the drying effect and ensuring the stability of the drying process.

[0051] In some examples, a moisture-absorbing sponge layer 14 is detachably provided on the cover plate 53 or the strip seat 51. It should be noted that the moisture-absorbing sponge layer 14 has a breathable effect and does not excessively affect the dissipation of heat.

[0052] For example, Figure 3 and Figure 4As shown, a detachable moisture-absorbing sponge layer 14 is provided on the cover plate 53 or the strip-shaped seat 51 of the external heating plate 5. When the textile fabric 3 is heated and dried, water vapor evaporates. The moisture-absorbing sponge layer 14, which is not in contact with the textile fabric 3, absorbs this water vapor, preventing it from accumulating inside the device and reattaching to the textile fabric 3, which could affect the drying effect. After the moisture-absorbing sponge layer 14 has absorbed a certain amount of moisture, it can be removed from the cover plate 53 or the strip-shaped seat 51 and aired or replaced to ensure its continued moisture absorption capacity. Furthermore, the sponge layer in contact with the textile fabric 3 absorbs moisture from the textile fabric 3 due to the slight pushing effect of the external heating plate 5, improving the drying effect. Furthermore, the moisture-absorbing sponge layer's thickness and flexibility prevent the textile fabric 3 from being damaged by being pulled. The provision of the moisture-absorbing sponge layer 14 effectively absorbs water vapor generated during the drying process, preventing secondary contamination of the fabric by water vapor, ensuring drying quality, and accelerating drying speed. The detachable and portable installation design makes the maintenance and replacement of the moisture-absorbing sponge layer 14 very convenient, ensuring the continuous and stable operation of the equipment.
