Description

Technical Field

[0001] This invention relates to the field of fabric drying technology, and in particular to a device for drying suit fabric. Background Technology

[0002] Fabrics are indispensable in our daily lives. The fabric production process involves washing, dyeing, and drying, with drying being particularly crucial. Suit fabrics are often blends of wool, polyester, and cotton, making them softer than ordinary fabrics. They require higher drying temperatures and are prone to shrinkage, pilling, and wrinkling. For example, Chinese patent CN112899945A discloses a fabric drying device. This design uses a lifting component to move the fabric in an S-shape within the drying chamber, increasing drying time. Simultaneously, a feeding component collects different types of fabric, controlling the drying time based on the varying degrees of dryness of each fabric to achieve the drying of multiple types of fabrics.

[0003] However, the above scheme only adjusts the drying time according to the different drying requirements of different types of fabrics. If the moisture content of the same type of fabric is not evenly distributed before drying, using the same drying time for the same type of fabric with different moisture content may result in the lower moisture content of the same type of fabric being over-dried and the higher moisture content being under-dried, thus leading to a poor overall drying effect of the fabric. Summary of the Invention

[0004] Therefore, it is necessary to provide a suit fabric drying device to address the problem that current drying devices cannot adaptively adjust the drying time according to the moisture content of the fabric, resulting in uneven drying and poor drying effect.

[0005] The above objectives are achieved through the following technical solutions:

[0006] A suit fabric drying device, comprising:

[0007] A base is provided with a first heating roller and a second heating roller spaced apart. The first heating roller and the second heating roller are parallel to each other and have a recess between them. The fabric passes over the first heating roller and the second heating roller and hangs down at a preset height between the first heating roller and the second heating roller. The first heating roller and the second heating roller rotate to heat and dry the fabric, and the conveying direction of the fabric is from the first heating roller to the second heating roller.

[0008] A driving component that drives the first heating roller and the second heating roller to rotate, wherein when the driving component changes the rotation speed of the first heating roller, the rotation speed of the second heating roller remains unchanged;

[0009] The first heating roller can move vertically according to the moisture content of the fabric, thereby changing the transmission ratio between the drive assembly and the first heating roller. The rotation speed of the first heating roller is negatively correlated with the moisture content of the fabric.

[0010] The base has a vertical groove, the shaft of the first heating roller is located in the vertical groove, and a compression spring and a tension spring are provided in the vertical groove. The compression spring is located below the shaft of the first heating roller, and the tension spring is located above the shaft of the first heating roller.

[0011] The drive assembly includes a drive motor and two first conical friction wheels. The drive motor is mounted on the base. The two first conical friction wheels are engaged with the rotating shaft of the first heating roller to prevent rotation. The small ends of the two first conical friction wheels are close to each other, and the two first conical friction wheels can move axially along the rotating shaft of the first heating roller. A first belt is wound around the rotating shaft of the drive motor and the conical surfaces of the two first conical friction wheels. The vertical movement of the first heating roller can change the distance between the two first conical friction wheels, thereby changing the radius of the conical surface in contact with the first belt and the two first conical friction wheels.

[0012] Furthermore, a spring is provided between the two first conical friction wheels, and an upward-opening V-shaped block is provided below the two first conical friction wheels, with the large ends of the two first conical friction wheels sliding in contact with the inclined surface of the V-shaped block.

[0013] Furthermore, the suit fabric drying device also includes a winding mechanism for winding up the fabric conveyed by the second heating roller.

[0014] Furthermore, the drive assembly also includes a second conical friction wheel, which is anti-rotatingly engaged with the shaft of the first heating roller. The second conical friction wheel and the first conical friction wheel are the same size. The small end of the second conical friction wheel is fixedly connected to the large end of the first conical friction wheel via a connecting shaft, and the two are coaxially connected. The first conical friction wheel and the second conical friction wheel move synchronously. A second belt is wound around the conical surface of the second conical friction wheel and the shaft of the second heating roller.

[0015] Furthermore, a baffle is provided on the base, the baffle is located at the small end of the second conical friction wheel, the baffle is provided with a through groove, the through groove extends in the vertical direction, the conical surface of the second conical friction wheel is located in the through groove, and there is a gap between the through groove and the conical surface of the second conical friction wheel.

[0016] Furthermore, the winding mechanism includes a winding roller and a winding motor. The winding motor is mounted on the base. The winding roller is close to the second heating roller. The winding motor drives the winding roller to rotate, and the rotation speed of the winding roller is the same as the rotation speed of the second heating roller.

[0017] Furthermore, a first tensioning pulley is provided on the base, and the first tensioning pulley abuts against the first belt.

[0018] Furthermore, a second tensioning pulley is also provided on the base, and the second tensioning pulley abuts against the second belt.

[0019] The beneficial effects of this invention are:

[0020] This invention provides a suit fabric drying device. By setting a first heating roller whose rotation speed can be changed according to the moisture content of the fabric, the drying time can be adaptively adjusted for different parts of the fabric with different moisture contents, thereby ensuring that the fabric is dried evenly. This avoids over-drying or under-drying of the fabric due to using the same drying time when the fabric has different moisture contents, thus improving the drying quality of the fabric. At the same time, by setting a hanging fabric between the first heating roller and the second heating roller, the traction force of the second heating roller on the fabric can be adjusted by adjusting the amount of hanging fabric, thereby avoiding wrinkles when the second heating roller transports the fabric.

[0021] The present invention improves the drying efficiency of the fabric by arranging a first heating roller and a second heating roller at intervals on the base, with the fabric hanging down at a preset height between the first heating roller and the second heating roller. After the fabric is heated by the first heating roller, it is cooled between the first heating roller and the second heating roller, and then heated and dried by the second heating roller.

[0039] The following reference Figures 1-9 This application describes a garment fabric drying device.

[0040] A suit fabric drying device is suitable for drying various fabrics 400, especially suit fabrics 400. It includes a base 100 with platforms on both sides of the upper end. The fabric 400 to be dried is laid out on the platforms. A recess is located in the middle of the platform, and a drying rack 110 is positioned above the recess. A first heating roller 120 and a second heating roller 130 are horizontally spaced on the drying rack 110, and the first heating roller 120 and the second heating roller 130 are parallel to each other. One end of the fabric 400 passes over the first heating roller 120 and the second heating roller 130, and the fabric 400 hangs down between the first heating roller 120 and the second heating roller 130 at a preset height (the preset height refers to the height at which the fabric 400 hangs down when the second heating roller 130 rotates to pull the fabric 400, so that no wrinkles are formed between the fabric 400 and the second heating roller 130), ensuring that the fabric 400 is precisely positioned within the recess. A drive assembly 200 is provided on the drying rack 110, which drives the first heating roller 120 and the second heating roller 130 to rotate. One end of the fabric 400 is draped over the first heating roller 120 and the second heating roller 130, specifically as follows. Figure 1 and Figure 2 As shown, the first heating roller 120 rotates and pulls the fabric 400 to move on the platform. The second heating roller 130 rotates synchronously and pulls the fabric 400. The conveying direction of the fabric 400 is from the first heating roller 120 to the second heating roller 130. The rotation speed of the first heating roller 120 and the second heating roller 130 is the same, so that the amount of fabric 400 hanging between the first heating roller 120 and the second heating roller 130 does not change.

[0041] When the fabric 400 is on the first heating roller 120, the surface of the first heating roller 120 is heated. The first heating roller 120 rotates to perform a first drying of the fabric 400 and convey the fabric 400 to the recess of the base 100 for cooling. Under its own gravity, the fabric 400 naturally hangs down and stretches out. The second heating roller 130 rotates to pull the fabric 400 after the first drying, performing a second drying of the fabric 400. It can be understood that the rotation speed of the first heating roller 120 and the second heating roller 130 is the same, so that the fabric 400 can always maintain this state, that is, the fabric 400 always hangs down to a preset height and always remains in a stretched state. The traction force of the second heating roller 130 on the fabric 400 does not change, thereby avoiding wrinkles on the fabric 400 on the second heating roller 130. At the same time, the two drying processes greatly improve the drying efficiency of the fabric 400.

[0042] After processing and production, fabric 400 requires drying. The moisture content of fabric 400 before drying is generally uniform, although variations in moisture content are possible. When drying different moisture content areas of fabric 400, the drying temperature or time needs to be adjusted to ensure the drying effect and avoid over-drying leading to quality degradation or incomplete drying causing mold and deterioration. Generally, adjusting the drying time is used to ensure the drying effect because fabric 400 has limited temperature tolerance. If the moisture content is high, increasing the drying temperature may alter the physicochemical properties of the fabric 400, thus affecting its quality. Therefore, this embodiment also uses the method of adjusting the drying time to ensure the drying effect of fabric 400.

[0043] In this embodiment, the drying time of the fabric 400 is changed by altering the rotation speed of the first heating roller 120. Specifically, the rotation speed of the first heating roller 120 is negatively correlated with the moisture content of the fabric 400. It can be understood that when the moisture content of the fabric 400 is high, reducing the rotation speed of the first heating roller 120 increases the contact time between the fabric 400 and the first heating roller 120, thereby increasing the drying time of the fabric 400. Conversely, when the moisture content of the fabric 400 is low, increasing the rotation speed of the first heating roller 120 reduces the contact time between the fabric 400 and the first heating roller 120, thereby reducing the drying time of the fabric 400.

[0044] The first heating roller 120 can move vertically. Since the fabric 400 is wrapped around the first heating roller 120 and the second heating roller 130, when the part of the fabric 400 with a higher water content passes through the first heating roller 120, the fabric 400 has a higher water content and is heavier. The downward pressure of the fabric 400 on the first heating roller 120 increases, and the downward movement of the first heating roller 120 reduces the transmission ratio between the drive assembly 200 and the first heating roller 120, thereby reducing the rotational speed of the first heating roller 120. When the part of the fabric 400 with a lower water content passes through the first heating roller 120, the fabric 400 has a lower water content and is lighter. The downward pressure of the fabric 400 on the first heating roller 120 decreases, and the upward movement of the first heating roller 120 increases the transmission ratio between the drive assembly 200 and the first heating roller 120, thereby increasing the rotational speed of the first heating roller 120.

[0045] By changing the rotation speed of the first heating roller 120 to adapt to different moisture contents on the fabric 400, the situation of incomplete drying when the moisture content is too high and over-drying when the moisture content is too low is avoided. This results in the fabric 400 being dried more evenly, thus improving the drying quality of the fabric 400.

[0046] To enable the first heating roller 120 to move vertically according to the moisture content of the fabric 400, a vertical groove is provided on the drying rack 110 in this embodiment. The vertical groove is located at the rotatable connection between the rotating shaft of the first heating roller 120 and the drying rack 110. The vertical groove extends vertically and is equipped with a compression spring and a tension spring. Figure 5 and Figure 6As shown, the compression spring and the tension spring are located below and above the rotating shaft of the first heating roller 120, respectively. The ends of the compression spring and the tension spring away from the rotating shaft of the first heating roller 120 are fixedly installed in the vertical groove, while the ends close to the rotating shaft of the first heating roller 120 are rotatably connected to the rotating shaft of the first heating roller 120. That is, the compression spring and the tension spring are provided with limit rings (not shown in the figure). The limit rings are sleeved on the rotating shaft of the first heating roller 120, and the compression spring and the tension spring do not affect the rotation of the rotating shaft of the first heating roller 120. Under the weight of the first heating roller 120 itself, the compression spring is compressed by a certain amount and the tension spring is stretched by a certain amount. When the part of the fabric 400 with uniform moisture content is located on the first heating roller 120, the weight of the first heating roller 120 and the fabric 400 makes the first heating roller 120 subject to force balance in the vertical direction. When the moisture content on the fabric 400 increases, the weight of the fabric 400 increases, which causes the first heating roller 120 to move downward in the vertical direction. Conversely, when the moisture content on the fabric 400 decreases, the first heating roller 120 moves upward in the vertical direction under the action of the tension spring and the compression spring, thereby realizing the movement of the first heating roller 120 in the vertical direction.

[0047] It should be noted that other structures can also be used to achieve the vertical movement of the first heating roller 120. For example, only a compression spring can be set in the vertical groove, with the compression spring located below the rotating shaft of the first heating roller 120, or only a tension spring can be set in the vertical groove, with the tension spring located above the rotating shaft of the first heating roller 120. Both can achieve the vertical movement of the first heating roller 120.

[0048] Specifically, such as Figure 3 and Figure 6 As shown, the drive assembly 200 includes a drive motor 210 and two first conical friction wheels 230. The drive motor 210 is fixedly mounted on the drying rack 110. The two first conical friction wheels 230 are anti-rotationally engaged with the shaft of the first heating roller 120. That is, the end of the shaft of the first heating roller 120 extending out of the drying rack 110 is connected to the two first conical friction wheels 230 by a key. The small ends of the two first conical friction wheels 230 are close to each other, and the two first conical friction wheels 230 can move axially along the shaft of the first heating roller 120. A first pulley 220 is provided on the shaft of the drive motor 210. A first belt 240 is wound between the conical surfaces of the two first conical friction wheels 230 and the first pulley 220. When the first heating roller 120 moves in the vertical direction, it drives the two first conical friction wheels 230 to move in the vertical direction as well. At the same time as the two first conical friction wheels 230 move in the vertical direction, the two first conical friction wheels 230 move axially along the shaft of the first heating roller 120, thereby changing the radius of the conical surface of the first belt 240 in contact with the two first conical friction wheels 230, thus changing the transmission ratio between the drive motor 210 and the first heating roller 120.

[0049] It is understandable that the structure to achieve the above function could be an electrically controlled telescopic rod between the two first conical friction wheels 230. When the first heating roller 120 moves vertically, the electrically controlled telescopic rod extends and retracts to cause the two first conical friction wheels 230 to move axially along the axis of rotation of the first heating roller 120. Alternatively, a V-block 260 could be provided below the two first conical friction wheels 230 so that while the two first conical friction wheels 230 move vertically, they also move axially along the axis of rotation of the first heating roller 120.

[0050] In this embodiment, a V-block 260 is used. Specifically, a spring 250 is provided between the small ends of the two first conical friction wheels 230. The opening of the V-block 260 faces upward, and the large ends of the two first conical friction wheels 230 slide in contact with the inclined surface of the V-block 260. When the first heating roller 120 moves in the vertical direction, it drives the two first conical friction wheels 230 to move in the vertical direction as well. Under the action of the V-block 260 and the spring 250, the distance between the two first conical friction wheels 230 can be changed, thereby changing the radius of the conical surface of the first belt 240 in contact with the two first conical friction wheels 230.

[0051] For example, when the first heating roller 120 moves downward in the vertical direction, the large ends of the two first conical friction wheels 230 slide downward on the inclined surface of the V-block 260, causing the two first conical friction wheels 230 to overcome the pressure of the spring 250 and move closer to each other, thereby increasing the radius of the conical surface where the first belt 240 contacts the two first conical friction wheels 230, and reducing the rotational speed of the first heating roller 120 driven by the drive motor 210; when the first heating roller 120 moves upward in the vertical direction, the two first conical friction wheels 230 also move upward, and the two first conical friction wheels 230 move away from each other under the action of the spring 250, thereby decreasing the radius of the conical surface where the first belt 240 contacts the two first conical friction wheels 230, and increasing the rotational speed of the first heating roller 120 driven by the drive motor 210.

[0052] It should be noted that the drive component 200 is not limited to the structure described above. The drive component 200 can also be a variable speed motor. When the first heating roller 120 moves downward in the vertical direction, the variable speed motor reduces its speed to reduce the rotational speed of the first heating roller 120. When the first heating roller 120 moves upward in the vertical direction, the variable speed motor increases its speed to increase the rotational speed of the first heating roller 120. Of course, other structures are also possible, which will not be described in detail here.

[0053] In a further embodiment, the suit fabric drying device also includes a winding mechanism 300, which is used to wind up the fabric 400 conveyed by the second heating roller 130. When the drive component 200 changes the rotation speed of the first heating roller 120, the rotation speed of the second heating roller 130 remains unchanged, so that the fabric 400 can be evenly conveyed to the winding mechanism 300, making it easier for the winding mechanism 300 to wind up the fabric 400, while avoiding wrinkles on the fabric 400 on the second heating roller 130.

[0054] Specifically, in this embodiment, a special structure is used so that when the rotational speed of the first heating roller 120 changes, the rotational speed of the second heating roller 130 remains unchanged from its initial speed. For example... Figure 6 As shown, the drive assembly 200 also includes a second conical friction wheel 231. The second conical friction wheel 231 is anti-rotatingly engaged with the shaft of the first heating roller 120, meaning that the second conical friction wheel 231 rotates synchronously with the first heating roller 120, while the first heating roller 120 does not restrict the second conical friction wheel 231 from moving axially along the first heating roller 120. The small end of the second conical friction wheel 231 is fixedly connected to the large end of the first conical friction wheel 230 via a connecting shaft, and the two are coaxially connected, so that there is a gap between the second conical friction wheel 231 and the first conical friction wheel 230. This ensures that the V-block 260 does not affect the movement of the second conical friction wheel 231, and the second conical friction wheel 231 and the first conical friction wheel 230 have the same size and the same conical surface slope. A second pulley 221 is coaxially mounted on the shaft of the second heating roller 130. The size of the second pulley 221 is exactly the same as that of the first pulley 220. A second belt 241 is wound around the conical surface of the second pulley 221 and the second conical friction wheel 231. The second conical friction wheel 231 moves synchronously with the first conical friction wheel 230. The drive motor 210 drives the first heating roller 120 to rotate, and the first heating roller 120 drives the second heating roller 130 to rotate. When the first heating roller 120 moves in the vertical direction, the two first conical friction wheels 230... The distance between them will change, that is, the two first conical friction wheels 230 will move away from each other or closer to each other along the axial direction of the first heating roller 120, thereby changing the transmission ratio between the first heating roller 120 and the drive motor 210. At the same time, since the second conical friction wheel 231 is fixedly connected to the first conical friction wheel 230 through the connecting shaft, the second conical friction wheel 231 and the first conical friction wheel 230 rotate synchronously and move synchronously along the axial direction of the first heating roller 120, thereby changing the transmission ratio between the second heating roller 130 and the first heating roller 120.

[0055] To prevent the second belt 241 on the second conical friction wheel 231 from falling off, a baffle 140 is provided on the base 100. The baffle 140 is located near the small end of the second conical friction wheel 231, specifically as follows: Figure 8 and Figure 9As shown, a through groove is provided on the baffle 140, which extends vertically. The conical surface of the second conical friction wheel 231 is located in the through groove, but the conical surface does not contact the through groove but has a gap, providing space for the second conical friction wheel 231 to move along its axial direction and rotate around its own axis. At the same time, the surface of the baffle 140 is smooth, one side of the second belt 241 is in frictional contact with the conical surface of the second conical friction wheel 231, and the other side of the second belt 241 is in sliding contact with the baffle 140, thereby preventing the second belt 241 from falling off the second conical friction wheel 231. Simultaneously, when the two first conical friction wheels 230 approach each other, the first conical friction wheel 230 connected to the second conical friction wheel 231 synchronously drives the second conical friction wheel 231 to move towards the first heating roller 120. Since the position of the baffle 140 is fixed and the baffle 140 blocks the second belt 241, the second conical friction wheel 231 can push the belt to move on its conical surface when it moves towards the first heating roller 120, thereby increasing the contact radius between the second belt 241 and the conical surface of the second conical friction wheel 231.

[0056] For example, when the first heating roller 120 moves downward in the vertical direction, the distance between the two first conical friction wheels 230 decreases, and the radius of the conical surface where the first belt 240 contacts the two first conical friction wheels 230 increases. This reduces the transmission ratio between the drive motor 210 and the first heating roller 120. Since the speed of the drive motor 210 remains constant, the speed of the first heating roller 120 decreases. Meanwhile, the radius of the conical surface where the second belt 241 contacts the second conical friction wheel 231 also increases, increasing the transmission ratio between the first heating roller 120 and the second heating roller 130. Since the second heating roller 130 is driven by the first heating roller 120, the rotational speed of the first heating roller 120 decreases, while the transmission ratio between the first heating roller 120 and the second heating roller 130 increases significantly. This is equivalent to the rotational speed of the second heating roller 130 remaining unchanged, or in other words, the rotational speed of the second heating roller 130 being the same as the rotational speed of the drive motor 210, and remaining constant. The second heating roller 130 conveys the fabric 400 at a constant speed, allowing the fabric 400 to be output at a uniform speed, which facilitates the winding mechanism 300 to wind up the fabric 400.

[0057] It should be noted that the suit fabric drying device is suitable for drying various fabrics 400. Whenever a different type of fabric 400 is changed, the height of the fabric 400 hanging between the first heating roller 120 and the second heating roller 130 needs to be adjusted, that is, the preset height of the fabric 400 hanging is adjusted, so as to ensure that the fabric 400 does not wrinkle when different types of fabrics 400 are heated and dried. If the moisture content of the fabric 400 is unevenly distributed, that is, on the same section of fabric 400, some parts have more moisture content and some parts have less moisture content, the downward pressure of the fabric 400 on the first heating roller 120 will be different when the fabric 400 passes through the first heating roller 120. If the part of the fabric 400 with more moisture content passes through the first heating roller 120, the first heating roller 120 will move downward, causing the two first conical friction wheels 230 on the first heating roller 120 to slide downward on the inclined surface of the V-block 260, thereby reducing the transmission ratio between the drive motor 210 and the first heating roller 120, and reducing the rotation speed of the first heating roller 120. The contact time between the portion of fabric 400 with higher moisture content and the first heating roller 120 increases. At this time, the rotation speed of the second heating roller 130 remains unchanged, and the output speed of fabric 400 remains constant. However, the rotation speed of the first heating roller 120 decreases, thus reducing the input speed of fabric 400. This reduces the amount of fabric 400 drooping between the first heating roller 120 and the second heating roller 130. However, due to the higher moisture content of fabric 400, its weight increases. Therefore, the traction force of the second heating roller 130 on fabric 400 remains unchanged, thus avoiding wrinkles in fabric 400 caused by changes in traction force.

[0058] After the portion of fabric 400 with high moisture content is dried and rolled up, and the subsequent moisture content of fabric 400 is evenly distributed, the downward pressure on fabric 400 passing through the first heating roller 120 is smaller than the downward pressure on the portion with high moisture content. Therefore, the first heating roller 120 moves upward in the vertical direction, and the rotation speed of the first heating roller 120 increases, exceeding the normal rotation speed. This increases the speed at which the first heating roller 120 conveys fabric 400, while the speed at which the second heating roller 130 conveys fabric 400 remains unchanged. Consequently, the amount of fabric 400 between the first heating roller 120 and the second heating roller 130 increases. With more fabric 400, the gravity increases, causing the rotation speed of the first heating roller 120 to decrease. The drooping height of the fabric 400 gradually returns to the preset height, and the rotation speed of the first heating roller 120 also gradually returns to the rotation speed under normal moisture content conditions for fabric 400. During this process, the traction force of the second heating roller 130 on the fabric 400 does not change. In other words, the moisture content of the fabric 400 does not affect the traction force of the second heating roller 130 on the fabric 400, thereby avoiding the formation of wrinkles in the fabric 400.

[0059] Similarly, when the portion of fabric 400 with a lower moisture content passes through the first heating roller 120, the adjustment process is the reverse of the above process, which will not be described in detail here.

[0060] Specifically, the winding mechanism 300 includes a winding roller 320 and a winding motor 310, such as Figure 1 As shown, the winding motor 310 is fixedly mounted on the base 100, and the winding roller 320 is close to the second heating roller 130. The winding motor 310 drives the winding roller 320 to rotate, thereby winding the fabric 400 output from the second heating roller 130. The rotation speed of the winding roller 320 is the same as the rotation speed of the second heating roller 130. The fabric 400 between the winding roller 320 and the second heating roller 130 has a certain tension to ensure that the fabric 400 avoids wrinkles during winding.

[0061] Of course, since the second heating roller 130 and the take-up roller 320 rotate at the same speed, and the second heating roller 130 is driven by the first heating roller 120, which is driven by the drive motor 210, the rotation speed of the second heating roller 130 remains constant. Therefore, the take-up roller 320 can also be driven to rotate by the drive motor 210, or the take-up roller 320 can be driven to rotate by the second heating roller 130, as long as the rotation speed of the second heating roller 130 and the take-up roller 320 is the same.

[0062] In a further embodiment, the base 100 is also provided with a first tensioning wheel 270 and a second tensioning wheel 271. The first tensioning wheel 270 is located above the first belt 240 and abuts against the first belt 240 to keep the first belt 240 in a tensioned state. In the initial state, the first tensioning wheel 270 abuts against the first belt 240. When the distance between the two first conical friction wheels 230 changes, the contact radius between the first belt 240 and the conical surfaces of the two first conical friction wheels 230 changes. The first tensioning wheel 270 moves in the vertical direction to ensure that the first belt 240 is always in a tensioned state. Specifically, the connecting rod connecting the first tensioning wheel 270 is a telescopic rod. The telescopic rod extends and retracts in the vertical direction, and the telescopic rod causes the first tensioning wheel 270 to have a downward tendency to keep the first belt 240 in a tensioned state. Similarly, the second tensioning pulley 271 is located on the second belt 241 and has the same function as the first tensioning pulley 270. The connecting rod connecting the second tensioning pulley 271 is also a telescopic rod, and its telescopic function is the same as that of the first tensioning pulley 270. Both of these make the second tensioning pulley 271 tend to move downward, so that the second belt 241 is in a tensioned state.

[0063] The specific working process of the suit fabric drying device provided in this application is described below with reference to the above embodiments:

[0064] The fabric 400 to be dried is placed on the first heating roller 120 and the second heating roller 130. The height of the fabric 400 hanging between the first heating roller 120 and the second heating roller 130 is adjusted according to the type and moisture content of the fabric 400 (the height is adjusted because the weight of different types and moisture contents of the fabric 400 is different, and the traction force of the second heating roller 130 on the fabric 400 is related to the weight of the fabric 400. Adjusting the height of the fabric 400 between the first heating roller 120 and the second heating roller 130 also adjusts the amount of fabric 400 between the first heating roller 120 and the second heating roller 130, thereby changing the traction force on the fabric 400. When the fabric 400 is subjected to appropriate traction force, wrinkles will not occur). After the adjustment is completed, the drive motor 210 and the winding motor 310 are started, and the first heating roller 120 and the second heating roller 130 start heating at the same time.

[0065] The rotation of the first heating roller 120 pulls the fabric 400 between the first heating roller 120 and the second heating roller 130. The fabric 400 undergoes a first drying process when passing through the first heating roller 120, and is cooled between the first heating roller 120 and the second heating roller 130. The rotation of the second heating roller 130 pulls the fabric 400 between the first heating roller 120 and the second heating roller 130 onto the second heating roller 130 for a second drying process. Under normal moisture content, the rotation speeds of the first heating roller 120 and the second heating roller 130 are the same. That is, the speed at which the first heating roller 120 inputs the fabric 400 is the same as the speed at which the second heating roller 130 outputs the fabric 400. The amount of fabric 400 between the first heating roller 120 and the second heating roller 130 does not change, and the height of the fabric 400 hanging does not change. This means that the traction force of the second heating roller 130 on the fabric 400 does not change. In other words, a suitable traction force can prevent the fabric 400 from wrinkling.

[0066] Different parts of the same fabric 400 may have different moisture contents. When the part of the fabric 400 with higher moisture content passes through the first heating roller 120, the weight of the fabric 400 increases due to the higher moisture content, and the downward pressure on the first heating roller 120 from the fabric 400 increases. The first heating roller 120 moves downward, further compressing the compression spring and stretching the tension spring. The downward movement of the first heating roller 120 drives the two first conical friction wheels 230 to move downward. The large ends of the two first conical friction wheels 230 slide into contact with the inclined surface of the V-block 260, causing the two first conical friction wheels 230 to overcome the force of the spring 250 and move closer to each other. The radius of the conical surface on both sides of the first belt 240 that contacts the two first conical friction wheels 230 increases, the transmission ratio between the drive motor 210 and the first heating roller 120 decreases, the rotation speed of the first heating roller 120 decreases, and the contact time between the fabric 400 and the first heating roller 120 increases. Since the rotation speed of the first heating roller 120 decreases, that is, the conveying speed of the fabric 400 decreases, the amount of fabric 400 between the first heating roller 120 and the second heating roller 130 decreases. However, since the moisture content of the fabric 400 increases, the overall weight of the fabric 400 does not change, that is, the traction force on the fabric 400 does not change.

[0067] Simultaneously, as the first conical friction wheel 230 approaches each other, it drives the second conical friction wheel 231 to move. The radius of the conical surface where the second belt 241 contacts the second conical friction wheel 231 increases, thereby increasing the transmission ratio between the first heating roller 120 and the second heating roller 130. However, since the rotational speed of the first heating roller 120 decreases, the rotational speed of the second heating roller 130 remains unchanged. The second heating roller 130 continuously and evenly outputs the fabric 400 to the take-up roller 320. The rotational speed of the take-up roller 320 is the same as that of the second heating roller 130. The fabric 400 between the take-up roller 320 and the second heating roller 130 has a certain tension, which prevents wrinkles from forming when the take-up roller 320 takes up the fabric 400.

[0068] When the portion of fabric 400 with high moisture content passes through the first heating roller 120 and the second heating roller 130, and the moisture content of the subsequent fabric 400 returns to normal, the moisture content of the fabric 400 on the first heating roller 120 is normal, while the amount of fabric 400 between the first heating roller 120 and the second heating roller 130 is less than the amount when the moisture content was normal before. The first heating roller 120 rises under the action of the compression spring and the tension spring, and the height of the rise exceeds the height when the moisture content of the fabric 400 was normal before. As a result, the two first conical friction wheels 230 move away from each other under the action of the V-block 260 and the spring 250. The transmission ratio between the drive motor 210 and the first heating roller 120 increases, the rotational speed of the first heating roller 120 increases and exceeds the rotational speed when the fabric 400 has normal moisture content, the conveying speed of the fabric 400 increases, and the fabric 400 between the first heating roller 120 and the second heating roller 130 gradually returns to the original normal moisture content, and the rotational speed of the first heating roller 120 also gradually returns to the original normal speed. The entire adjustment process is an adaptive dynamic adjustment process, which keeps the traction force of the second heating roller 130 on the fabric 400 constant. That is to say, the amount of moisture content of the fabric 400 does not affect the traction force of the second heating roller 130 on the fabric 400, so that the fabric 400 conveyed by the second heating roller 130 has almost no wrinkles. Then, the dried fabric 400 is wound up by the take-up roller 320.

[0069] Similarly, when the portion of fabric 400 with a lower moisture content passes through the first heating roller 120, the adjustment process is the reverse of the above process, which will not be described in detail here.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
