Description

Technical Field

[0001] This invention relates to the field of sofa fabric drying technology, specifically to an antibacterial finishing and drying device for sofa fabric. Background Technology

[0002] When antibacterial finishing is performed on fabrics, the drying process is crucial to ensure the effective fixation of antibacterial agents and achieve durable performance. During the drying process, fabrics need to go through a pre-drying stage and a curing stage. The drying temperature in the pre-drying stage is 80~100℃ to avoid surface migration of antibacterial agents caused by high temperature. The drying temperature in the curing stage needs to be adjusted according to the type of antibacterial agent. For example, nano-silver usually requires 120~150℃, and quaternary ammonium salts require 160~180℃. The above drying process needs to gradually increase the temperature, such as 80℃-120℃-150℃, to prevent sudden heating that could cause fabric deformation or decomposition of antibacterial agents. Therefore, when transitioning from the pre-drying stage to the curing stage, the temperature of the fabric must be maintained to avoid a sudden increase in temperature after the fabric has cooled down.

[0003] The pre-drying time in the above-mentioned pre-drying stage is 5-10 minutes, and the curing time in the curing stage is 3-5 minutes. Therefore, when the moving speed of the sofa fabric during drying increases, the drying time will be shortened accordingly, making it impossible for the pre-drying and curing of the sofa fabric to achieve the expected effect, thus affecting the antibacterial quality of the sofa fabric. Conversely, the sofa fabric is prone to overheating, which will destroy the antibacterial agent and also affect the antibacterial quality of the sofa fabric. Therefore, when the moving speed of the sofa fabric during drying is adjusted, the drying temperature also needs to be adjusted accordingly. However, the controllability of temperature adjustment is low, and repeated experiments are required to ensure the pre-drying and curing effects. This is time-consuming and laborious, and cannot meet diverse usage needs.

[0004] A search revealed that Chinese patent application CN113293623B discloses a production process for antibacterial nano-printed fabric and a special device for setting and drying it. Although this enhances the antibacterial properties of the printed fabric and improves its setting effect, it cannot solve the aforementioned problems. The fabric's movement speed cannot automatically match the drying time, and the speed cannot be adjusted according to production needs. Furthermore, the pre-drying time and curing time differ, and the ratio of pre-drying time to curing time varies depending on the fabric thickness or the antibacterial agent used. To ensure simultaneous pre-drying and curing, the fabric must be continuously transported, resulting in uniform movement speeds across all parts and a fixed ratio of pre-drying time to curing time, thus failing to allow for adjustments to the drying time. Summary of the Invention

[0010] As a further embodiment of the present invention: the fan housing is fixedly connected to the side wall of the housing, the turbofan is rotatably sleeved to the side wall of the housing, the piston rod is slidably sleeved to the sealed cylinder, the piston ring is fixedly connected to the end of the sealed cylinder, and the sealed cylinder is fixedly connected to the side wall of the housing, a one-way valve is installed on the outer surface of the sealed cylinder, the auxiliary conveyor belt is rotatably sleeved to the side wall of the housing, the first screw is located in the first slide groove, and the first screw is engaged with the slide frame.

[0011] As a further aspect of the present invention: one end of a transmission chain is fixedly connected to the end of the first screw, the other end of the transmission chain is fixedly connected to one end of a rotating shaft, the other end of the rotating shaft is rotatably connected to a bracket, and a driving gear is fixedly connected to the outer surface of the rotating shaft. A driven gear is meshed with the outer surface of the driving gear, and a rotating rod is fixedly connected to the central axis of the driven gear. A cavity is opened inside the rotating rod, and a second lead screw is meshed and sleeved on the end face of the rotating rod. An insert is rotatably connected to the end face of the second lead screw, and an adjusting gear is sleeved on the outer surface of the rotating rod. The adjusting gear is fitted and connected to the insert, and a multi-stage gear is meshed and connected to the outer surface of the adjusting gear. A second screw is fixedly connected to the central axis of the multi-stage gear, and the second screw is meshed and sleeved with a slider.

[0012] As a further aspect of the present invention: the second screw is located in the second slide groove, and the second screw is rotatably sleeved with the side wall of the housing, the rotating rod is rotatably connected to the side wall of the housing, the bracket is fixedly connected to the side wall of the housing, the diameter of the multi-stage gear gradually increases, and the diameter of the adjusting gear gradually decreases.

[0013] As a further embodiment of the present invention: the insert is fitted into the cavity, the second lead screw extends into the cavity, and the pitch of the second lead screw is equal to the pitch of the first lead screw.

[0014] Compared with the prior art, the beneficial effects of the present invention, using the above technical solution, are as follows:

[0015] This invention connects two hot air blowers to a first and a second air-collecting shell, respectively, allowing the fabric in the first air-collecting shell to undergo pre-drying and the fabric in the second air-collecting shell to undergo curing. Simultaneously, the length of the fabric in the first air-collecting shell is twice the length of the fabric in the second air-collecting shell, based on the speed-time formula... It is known that, at the same moving speed, the ratio of pre-drying time to curing time is the ratio of the length of the pre-drying stage to the length of the curing stage. Therefore, the pre-drying time is twice the curing time, which meets the time requirements in the background technology. This allows the fabric to pass through the pre-drying stage and the curing stage sequentially in the chamber, so that the pre-drying stage and the curing stage do not need to be carried out separately. This avoids the fabric from being heated again after cooling down, and the temperature gradually increases throughout the drying process. This prevents the fabric from deforming or the antibacterial agent from decomposing due to sudden heating, ensuring the quality of the fabric. At the same time, it simplifies the drying process and eliminates the need to transfer the fabric.

[0016] This invention accelerates the rotation of the turbofan by using a conveyor roller, thereby increasing the airflow generated by the turbofan and consequently increasing the airflow into the sealed cylinder through the duct. At this point, the airflow entering the sealed cylinder is significantly greater than the airflow discharged from the one-way valve, causing the air pressure between the piston rod and piston rings to rise. This leads to the piston rod gradually contracting into the sealed cylinder, continuously compressing the air at the end of the sealed cylinder. As the piston rod continues to move, the space between the piston rod and piston rings increases, and the air pressure gradually decreases until the air pressure on both sides of the piston rod rebalances. At this point, the rotational speed of the turbofan and the conveyor roller has reached the target value. It should be further noted that the aforementioned piston rod contraction... Upon entering the sealed cylinder, the distance between the piston rod and the first lead screw continuously shortens, while the first lead screw engages with the piston rod. Simultaneously, the first lead screw is fixed to the sealed cylinder, causing the piston rod to rotate while contracting and translating. This causes the piston rod to drive the insert strip to rotate, resulting in the rotation of the secondary conveyor belt on the insert strip. This, in turn, causes the first screw on the secondary conveyor belt to rotate. The first screw engages with the slide, while the slide is slidably connected to the first slide groove and cannot rotate. This allows the slide to translate under the drive of the first screw, causing the slide to move the first adjusting roller away from the conveyor roller. This increases the length of the sofa fabric inside the first air-collecting shell by an amount that is... Where V1 is the fabric's moving speed after the speed increase, V0 is the fabric's initial moving speed, and t is the fabric's pre-drying time, which is a constant. At this time, the moving distance between the carriage and the first adjusting roller is... In summary, as the fabric moving speed increases, the pre-drying time remains constant, allowing the fabric moving speed and drying time to automatically match. The fabric moving speed can be adjusted according to production needs, ensuring that the pre-drying of the fabric achieves the expected results without adjusting the drying temperature. This makes the pre-drying effect of the fabric controllable, eliminating the need for repeated temperature adjustments and avoiding affecting the quality of the fabric. The drying device can adapt to diverse usage needs.

[0017] This invention uses a multi-stage gear system to drive a second screw to rotate, causing a slider on the second screw to move a second adjusting roller horizontally, moving the second adjusting roller away from the conveying roller. Since the second screw has the same pitch as the first screw, the movement distance of the second adjusting roller is equal to that of the first adjusting roller. The increase in fabric length within the second air-collecting shell is equal to the movement distance of the second adjusting roller. Therefore, the fabric length within the first air-collecting shell remains twice the fabric length within the second air-collecting shell. This ensures that changes in the fabric's movement speed do not affect the drying time, further guaranteeing both pre-drying and curing effects. When the time ratio between the pre-drying and curing stages changes, the second lead screw on the rotating rod is rotated. This causes the second lead screw to extend into the cavity, pushing the insert towards the adjusting gear with a reduced diameter. This reduces the diameter of the adjusting gear driven by the rotating rod, thus decreasing the linear velocity of the multi-stage gear. Meanwhile, the diameter of the multi-stage gear corresponding to the reduced-diameter adjusting gear increases, further reducing the angular velocity of the multi-stage gear. Consequently, the number of rotations of the second lead screw decreases, resulting in a smaller change in the fabric length within the second air-collecting shell. This indirectly changes the ratio of fabric length during pre-drying to curing, allowing the ratio of pre-drying time to curing time to be adjustable. This can meet the needs of fabrics of different thicknesses or with different antibacterial agents, and further allows for adjustments to the drying time. Attached Figure Description

[0029] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Example 1, please refer to Figures 1-3 , Figure 6 and Figure 7 This invention provides a technical solution: an antibacterial finishing and drying device for sofa fabric, comprising a housing 1, a first air-collecting shell 2 and a second air-collecting shell 3 fixedly connected to the inner side wall of the housing 1, an inlet 4 at the top of the housing 1, an outlet 5 at the bottom of the housing 1, and a motor 6 installed on the side wall of the housing 1. One end of a conveyor roller 7 is fixedly connected to the output end of the motor 6, and a main conveyor belt 8 is fixedly connected to the other end of the conveyor roller 7. Both ends of the main conveyor belt 8 are meshed with transmission gears. 9. A pressure roller 10 is fixedly connected to the central axis of the transmission gear 9. A first slide groove 11 and a second slide groove 12 are provided on the inner side wall of the housing 1. A guide roller 13 is rotatably connected to the inner side wall of the housing 1. A slide frame 14 is slidably connected in the first slide groove 11. A first adjusting roller 15 is rotatably connected to the side wall of the slide frame 14. A slider 16 is slidably connected in the second slide groove 12. A second adjusting roller 17 is rotatably connected to the side wall of the slider 16. A hot air blower 40 is installed on the side wall of the housing 1.

[0031] Please see Figure 6There are two sliders 16 and two carriages 14, and the two sliders 16 and two carriages 14 are symmetrically arranged about the bisecting plane of the housing 1. The first adjusting roller 15 is located between the two carriages 14, and the second adjusting roller 17 is located between the two sliders 16. There are two conveying rollers 7 and two pressure rollers 10, and the two conveying rollers 7 are located at the inlet 4 and the outlet 5, and the two pressure rollers 10 are located at the inlet 4 and the outlet 5.

[0032] Please see Figure 2 , Figure 3 and Figure 6 The length of the sofa fabric inside the first air-collecting shell 2 is twice the length of the sofa fabric inside the second air-collecting shell 3. There are two hot air blowers 40, one of which is connected to the first air-collecting shell 2 and the other of which is connected to the second air-collecting shell 3.

[0033] Specifically, during the process of the sofa fabric entering the housing 1, the hot air blower 40 and the electric motor 6 are started simultaneously. The electric motor 6 drives the lower conveyor roller 7 to rotate, thereby causing the main conveyor belt 8 between the two conveyor rollers 7 to rotate. The main conveyor belt 8 drives the transmission gears 9 at both ends to rotate, which in turn causes the pressure rollers 10 on the transmission gears 9 to rotate. The pressure rollers 10 rotate in the opposite direction to the conveyor rollers 7, thus realizing the conveying of the sofa fabric. The two hot air blowers 40 are respectively connected to the first air-collecting shell 2 and the second air-collecting shell 3, so that the sofa fabric in the first air-collecting shell 2 undergoes a pre-drying operation, and the sofa fabric in the second air-collecting shell 3 undergoes a curing operation. At the same time, the length of the sofa fabric in the first air-collecting shell 2 is twice the length of the sofa fabric in the second air-collecting shell 3. According to the speed and time formula... It is known that, at the same moving speed, the ratio of pre-drying time to curing time is the ratio of the length of the pre-drying stage to the length of the curing stage. Therefore, the pre-drying time is twice the curing time, which meets the time requirements in the background technology. This allows the fabric to pass through the pre-drying stage and the curing stage sequentially in the chamber 1, so that the pre-drying stage and the curing stage do not need to be carried out separately. This avoids the fabric from being heated again after cooling down, and the temperature gradually increases throughout the drying process. This prevents the fabric from deforming or the antibacterial agent from decomposing due to sudden heating, ensuring the quality of the fabric. At the same time, it simplifies the drying process and eliminates the need to transfer the fabric.

[0034] Example 2, please refer to Figure 2 and Figures 8-10The present invention provides a technical solution: an antibacterial finishing and drying device for sofa fabric, wherein a turbine fan 18 is fixedly connected to the end of a conveyor roller 7, a fan housing 19 is provided over the turbine fan 18, one end of a conduit 20 is connected to the outer surface of the fan housing 19, the other end of the conduit 20 is connected to a sealed cylinder 21, a first lead screw 22 is fixedly connected to the end face of the sealed cylinder 21, a piston rod 23 is meshed and sleeved on the outer surface of the first lead screw 22, a piston ring 24 is slidably sleeved on the outer surface of the piston rod 23, and an insert 25 is embedded and connected to the outer surface of the piston rod 23. One end of a secondary conveyor belt 26 is fixedly connected to the side wall of the insert 25, and a first screw 27 is fixedly connected to the other end of the secondary conveyor belt 26.

[0035] Please see Figures 7-10 The fan housing 19 is fixedly connected to the side wall of the housing 1, the turbofan 18 is rotatably sleeved to the side wall of the housing 1, the piston rod 23 is slidably sleeved to the sealed cylinder 21, the piston ring 24 is fixedly connected to the end of the sealed cylinder 21, and the sealed cylinder 21 is fixedly connected to the side wall of the housing 1. A one-way valve is installed on the outer surface of the sealed cylinder 21, the auxiliary conveyor belt 26 is rotatably sleeved to the side wall of the housing 1, the first screw 27 is located in the first slide groove 11, and the first screw 27 is meshed with the slide 14.

[0036] Specifically, during the process of accelerating the sofa fabric movement, according to the above principle, the rotational speed of the conveying roller 7 and the pressure roller 10 gradually increases, thereby increasing the rotational speed of the turbine fan 18 on the conveying roller 7. This leads to a gradual increase in the airflow generated by the turbine fan 18, which in turn increases the airflow flowing from the duct 20 into the sealed cylinder 21. At this time, the airflow entering the sealed cylinder 21 is much greater than the airflow discharged by the one-way valve, causing the air pressure between the piston rod 23 and the piston ring 24 to rise. Since the interface between the duct 20 and the sealed cylinder 21 is located between the piston rod 23 and the piston ring 24, the air introduced by the duct 20 is located between the piston rod 23 and the piston ring 24, i.e., the right end of the sealed cylinder 21. When the air pressure at the right end of the sealed cylinder 21 rises, the pressure at the right end is greater than the air pressure at the left end, causing the high-pressure gas to push the piston rod 23 to move from right to left, causing the piston rod 23 to gradually contract into the sealed cylinder 21 and continuously compress the air at the end of the sealed cylinder 21. At this time, as the piston rod 23 continues to move, the piston rod 23... As the space between the piston rod 23 and piston ring 24 increases, the air pressure gradually decreases until the air pressure on both sides of piston rod 23 is rebalanced. At this point, the rotational speed of turbofan 18 and conveyor roller 7 has reached the target value. It should be further explained that when piston rod 23 retracts into sealed cylinder 21, the distance between piston rod 23 and first lead screw 22 continuously shortens. First lead screw 22 engages with piston rod 23, and is fixed to sealed cylinder 21, causing piston rod 23 to rotate while retracting and translating. This causes piston rod 23 to drive insert 25 to rotate, causing secondary conveyor belt 26 on insert 25 to rotate, which in turn causes first screw 27 on secondary conveyor belt 26 to rotate. First screw 27 engages with slide 14, and slide 14 is slidably connected to first slide groove 11 and cannot rotate. This causes slide 14 to translate under the drive of first screw 27, causing slide 14 to move first adjusting roller 15 away from conveyor roller 7, increasing the length of sofa fabric inside first air-collecting shell 2. The increase is [missing information]. Where V1 is the increased moving speed of the sofa fabric, V0 is the initial moving speed of the sofa fabric, and t is a constant pre-drying time for the sofa fabric. At this time, the moving distance between the carriage 14 and the first adjusting roller 15 is... In summary, as the fabric moving speed increases, the pre-drying time remains constant, allowing the fabric moving speed and drying time to automatically match. The fabric moving speed can be adjusted according to production needs, ensuring that the pre-drying of the fabric achieves the expected results without adjusting the drying temperature. This makes the pre-drying effect of the fabric controllable, eliminating the need for repeated temperature adjustments and avoiding affecting the quality of the fabric. The drying device can adapt to diverse usage needs.

[0037] Example 3, please refer to Figures 2-6 and Figure 8The present invention provides a technical solution: an antibacterial finishing and drying device for sofa fabric, wherein one end of a transmission chain 28 is fixedly connected to the end of a first screw 27, and the other end of the transmission chain 28 is fixedly connected to one end of a rotating shaft 29. The other end of the rotating shaft 29 is rotatably connected to a bracket 30, and a driving gear 31 is fixedly connected to the outer surface of the rotating shaft 29. A driven gear 32 is meshed with the outer surface of the driving gear 31. A rotating rod 33 is fixedly connected to the central axis of the driven gear 32. A cavity 34 is opened inside the rotating rod 33, and a second lead screw 35 is meshed with the end face of the rotating rod 33. An insert 36 is rotatably connected to the end face of the second lead screw 35. An adjusting gear 37 is sleeved on the outer surface of the rotating rod 33. The adjusting gear 37 is fitted with the insert 36, and a multi-stage gear 38 is meshed with the outer surface of the adjusting gear 37. A second screw 39 is fixedly connected to the central axis of the multi-stage gear 38, and the second screw 39 is meshed with the slider 16.

[0038] Please see Figure 4 and Figure 6 The second screw 39 is located in the second slide groove 12 and is rotatably sleeved with the side wall of the housing 1. The rotating rod 33 is rotatably connected with the side wall of the housing 1. The bracket 30 is fixedly connected with the side wall of the housing 1. The diameter of the multi-stage gear 38 gradually increases and the diameter of the adjusting gear 37 gradually decreases.

[0039] Please see Figure 5 The insert 36 is fitted into the cavity 34, the second lead screw 35 extends into the cavity 34, and the pitch of the second screw 39 is equal to the pitch of the first screw 27.

[0040] Specifically, during the rotation of the first screw 27, the transmission chain 28 on the first screw 27 synchronously drives the rotating shaft 29 to rotate, causing the driving gear 31 on the rotating shaft 29 to drive the driven gear 32 to rotate, which in turn causes the rotating rod 33 on the driven gear 32 to rotate. The cavity 34 on the rotating rod 33 engages with the insert 36, and the insert 36 engages with the adjusting gear 37 of the corresponding diameter. This allows the rotation of the rotating rod 33 to drive the adjusting gear 37 of a specific diameter to rotate, while the other adjusting gears 37 cannot be driven. At this time, the adjusting gear of the specific diameter... The spur gear 37 drives the multi-stage gear 38 to rotate. The radii of the adjusting gear 37 with a specific diameter are equal to those of the corresponding multi-stage gear 38, causing the adjusting gear 37 and the multi-stage gear 38 to rotate synchronously in opposite directions. This causes the second screw 39 on the multi-stage gear 38 to rotate, causing the slider 16 on the second screw 39 to drive the second adjusting roller 17 to translate, moving the second adjusting roller 17 away from the conveying roller 7. Simultaneously, the pitch of the second screw 39 is the same as that of the first screw 27, so the displacement of the second adjusting roller 17 is equal to that of the first adjusting roller 15. Its second air-collecting shell 3... The increase in the fabric length inside the first air-collecting shell 2 is the same as the shift distance of the second adjusting roller 17. Therefore, the fabric length inside the first air-collecting shell 2 is still twice the fabric length inside the second air-collecting shell 3, ensuring that changes in the fabric speed do not affect the drying time, further guaranteeing the pre-drying and curing effects. When the time ratio between the pre-drying and curing stages changes, the second lead screw 35 on the rotating rod 33 is rotated, causing the second lead screw 35 to extend into the cavity 34, thereby pushing the insert 36 towards the adjusting gear 37 with a reduced diameter, so that the adjusting gear 37 driven by the rotating rod 33... As the diameter decreases, the linear velocity of the multi-stage gear 38 decreases. Meanwhile, the diameter of the multi-stage gear 38, which corresponds to the reduced-diameter adjustment gear 37, increases, further reducing the angular velocity of the multi-stage gear 38. Consequently, the number of rotations of the second screw 39 decreases, resulting in a smaller change in the fabric length within the second air-collecting shell 3. This indirectly changes the ratio of fabric length during pre-drying to curing, allowing the ratio of pre-drying time to curing time to be adjustable. This can meet the needs of fabrics of different thicknesses or with different antibacterial agents, and thus allow for adjustments to the drying time.

[0041] The working principle and usage process of this invention are as follows: When it is necessary to dry the sofa fabric, the sofa fabric adsorbed with antibacterial agent is put into the inlet 4 on the box 1, so that the sofa fabric passes through the first adjusting roller 15, the guide roller 13 and the second adjusting roller 17 in sequence, and moves continuously under the drive of the conveying roller 7 and the pressure roller 10, and finally is discharged from the outlet 5, completing the drying of the sofa fabric. In the above process, after the sofa fabric enters the box 1, the hot air blower 40 and the electric motor 6 are started simultaneously, so that the electric motor 6 drives the lower conveying roller 7 to rotate, thereby making the main conveyor between the two conveying rollers 7 rotate. The rotation of belt 8 causes the transmission gears 9 at both ends of the main conveyor belt 8 to rotate, which in turn causes the pressure rollers 10 on the transmission gears 9 to rotate. The pressure rollers 10 rotate in the opposite direction to the conveyor rollers 7, thus achieving the conveying of the aforementioned sofa fabric. Two hot air blowers 40 are respectively connected to the first air-collecting shell 2 and the second air-collecting shell 3, allowing the sofa fabric in the first air-collecting shell 2 to undergo pre-drying and the sofa fabric in the second air-collecting shell 3 to undergo curing. Simultaneously, the length of the sofa fabric in the first air-collecting shell 2 is twice the length of the sofa fabric in the second air-collecting shell 3, according to the speed-time formula... It is known that, at the same moving speed, the ratio of pre-drying time to curing time is the ratio of the length of the pre-drying stage to the length of the curing stage. Therefore, the pre-drying time is twice the curing time, which meets the time requirements in the background technology. This allows the fabric to pass through the pre-drying stage and the curing stage sequentially in the box 1, so that the pre-drying stage and the curing stage do not need to be separated. This avoids the reheating of the fabric after it has cooled down, and the temperature gradually increases throughout the drying process. This prevents the fabric from deforming or the antibacterial agent from decomposing due to sudden heating, ensuring the quality of the fabric. At the same time, it simplifies the drying process and eliminates the need to transfer the fabric.

[0042] When it is necessary to accelerate the movement of the sofa fabric, according to the above principle, the rotational speed of the conveyor roller 7 and the pressure roller 10 increases, thereby increasing the rotational speed of the turbine fan 18 on the conveyor roller 7. This increases the airflow generated by the turbine fan 18, which in turn increases the airflow flowing into the sealed cylinder 21 through the duct 20. At this time, the airflow entering the sealed cylinder 21 is much greater than the airflow discharged by the one-way valve, causing the air pressure between the piston rod 23 and the piston ring 24 to rise. This causes the piston rod 23 to gradually contract into the sealed cylinder 21, continuously compressing the air at the end of the sealed cylinder 21. As the piston rod 23 continues to move, the space between the piston rod 23 and the piston ring 24 increases, and the air pressure gradually decreases until the air pressure on both sides of the piston rod 23 is rebalanced. At this point, the rotational speed of the turbine fan 18 and the conveyor roller 7 has reached the target value. Further explanation is needed. When the piston rod 23 retracts into the sealed cylinder 21, the distance between the piston rod 23 and the first lead screw 22 continuously shortens. The first lead screw 22 engages with the piston rod 23, and is fixed to the sealed cylinder 21. This causes the piston rod 23 to rotate while retracting and translating, thus rotating the insert strip 25. This causes the secondary conveyor belt 26 on the insert strip 25 to rotate, which in turn causes the first screw 27 on the secondary conveyor belt 26 to rotate. The first screw 27 engages with the slide 14, and the slide 14 is slidably connected to the first slide groove 11 and cannot rotate. This causes the slide 14 to translate under the influence of the first screw 27, causing the slide 14 to move the first adjusting roller 15 away from the conveyor roller 7. This increases the length of the sofa fabric inside the first air-collecting shell 2, by an amount that is... Where V1 is the increased moving speed of the sofa fabric, V0 is the initial moving speed of the sofa fabric, and t is a constant pre-drying time for the sofa fabric. At this time, the moving distance between the carriage 14 and the first adjusting roller 15 is... In summary, when the fabric moving speed increases, the pre-drying time can remain constant, so that the fabric moving speed and drying time are automatically matched. The fabric moving speed can be adjusted according to production needs, so that the pre-drying of the fabric can achieve the expected effect without adjusting the drying temperature. This makes the pre-drying effect of the fabric controllable, avoids repeated temperature adjustments, avoids affecting the quality of the fabric, and the drying device can adapt to diverse usage needs.

[0043] As the first screw 27 rotates, the transmission chain 28 on the first screw 27 synchronously drives the rotating shaft 29 to rotate, causing the driving gear 31 on the rotating shaft 29 to drive the driven gear 32 to rotate, which in turn causes the rotating rod 33 on the driven gear 32 to rotate. The cavity 34 on the rotating rod 33 engages with the insert 36, and the insert 36 engages with the adjusting gear 37 of the corresponding diameter. This allows the rotation of the rotating rod 33 to drive the adjusting gear 37 of the specific diameter to rotate, while the other adjusting gears 37 cannot be driven. At this time, the adjusting gear 37 of the specific diameter... The multi-stage gear 38 is driven to rotate. The adjusting gear 37 of a specific diameter has the same radius as the corresponding multi-stage gear 38, causing the adjusting gear 37 and the multi-stage gear 38 to rotate synchronously in opposite directions. This causes the second screw 39 on the multi-stage gear 38 to rotate, causing the slider 16 on the second screw 39 to drive the second adjusting roller 17 to translate, moving the second adjusting roller 17 away from the conveying roller 7. At the same time, the pitch of the second screw 39 is the same as that of the first screw 27, so the displacement of the second adjusting roller 17 is equal to that of the first adjusting roller 15. The sofa fabric inside the second air-collecting shell 3... The increase is the displacement of the second adjusting roller 17. Therefore, the length of the sofa fabric inside the first air-collecting shell 2 is still twice the length of the sofa fabric inside the second air-collecting shell 3. This ensures that the change in the sofa fabric's movement speed does not affect the drying time, further guaranteeing the pre-drying and curing effects. When the time ratio between the pre-drying and curing stages changes, the second lead screw 35 on the rotating rod 33 is rotated, causing the second lead screw 35 to extend into the cavity 34. This pushes the insert 36 towards the adjusting gear 37 with a reduced diameter, thus reducing the diameter of the adjusting gear 37 driven by the rotating rod 33. Therefore, the linear velocity of the multi-stage gear 38 decreases, while the diameter of the multi-stage gear 38, corresponding to the reduced diameter of the adjusting gear 37, increases. Consequently, the angular velocity of the multi-stage gear 38 further decreases, resulting in a decrease in the number of rotations of the second screw 39. Consequently, the change in the fabric length inside the second air-collecting shell 3 is smaller, indirectly causing a change in the ratio of fabric length during pre-drying to curing. This allows the ratio of pre-drying time to curing time to be adjustable, meeting the needs of fabrics of different thicknesses or with different antibacterial agents. This, in turn, allows for the adjustment of drying time, thus completing the operation.
