Description

Technical Field

[0001] The invention relates to the technical field of sofa fabric drying, in particular to an antibacterial finishing and drying device for sofa fabrics. Background Art

[0002] When antibacterial finishing is performed on sofa fabrics, the drying process is a key step to ensure that the antibacterial agent is effectively fixed and achieves long-lasting performance. During the drying process, the sofa fabric needs to go through a pre-baking stage and a curing stage. The drying temperature in the pre-baking stage is 80~100℃ to avoid surface migration of the antibacterial agent caused by high temperature. The drying temperature in the curing stage needs to be adjusted according to the type of antibacterial agent. For example, nanosilver usually requires 120~150℃, and quaternary ammonium salts require 160~180℃. The above drying process needs to be heated gradually, such as 80℃-120℃-150℃, to prevent sudden heat from causing deformation of the fabric or decomposition of the antibacterial agent. Therefore, when transitioning from the pre-baking stage to the curing stage, the temperature of the sofa fabric needs to be maintained to avoid sudden heating after the sofa fabric cools down.

[0003] The pre-baking time of the above-mentioned pre-baking stage is 5 to 10 minutes, and the curing time of the curing stage is 3 to 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-baking and curing of the sofa fabric to achieve the expected results, thereby affecting the antibacterial quality of the sofa fabric. Conversely, the sofa fabric is prone to overheating, thereby destroying the antibacterial agent, which will 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. The controllability of the temperature adjustment is low, and repeated experiments are required to ensure the pre-baking and curing effects. This is time-consuming and labor-intensive, and cannot meet diverse usage needs.

[0004] After searching, Chinese patent application CN113293623B discloses a production process of antibacterial nano-printed cloth and a special device for shaping and drying thereof. Although it enhances the antibacterial properties of the printed cloth and improves the shaping effect of the printed cloth, it cannot solve the above-mentioned problems, so that the movement speed of the sofa cloth cannot be automatically matched with the drying time, and the movement speed of the sofa cloth cannot be adjusted according to production needs. At the same time, the pre-baking time is different from the curing time. The ratio of pre-baking time to curing time is different for fabrics of different thicknesses or fabrics with different antibacterial agents. In order to carry out the pre-baking and curing of the sofa cloth at the same time, the transmission of the sofa cloth needs to be continuous and coherent, so that the movement speed of each part is the same, so that the ratio of pre-baking time to curing time is fixed, and thus the adjustment of the drying time cannot be met.

[0011] As a further solution of the present invention: the end of the first screw is fixedly connected to one end of the transmission chain, the other end of the transmission chain is fixedly connected to one end of the rotating shaft, the other end of the rotating shaft is rotatably connected to the bracket, and the outer surface of the rotating shaft is fixedly connected to the driving gear, the outer surface of the driving gear is meshedly connected to the driven gear, the central axis of the driven gear is fixedly connected to a rotating rod, an embedding cavity is provided in the rotating rod, and a second screw is meshed and sleeved on the end surface of the rotating rod, an insert is rotatably connected on the end surface of the second screw, an adjusting gear is sleeved on the outer surface of the rotating rod, the adjusting gear is meshed and connected to the insert, and the outer surface of the adjusting gear is meshed and connected to a multi-stage gear, a second screw is fixed to the central axis of the multi-stage gear, and the second screw is meshed and sleeved on the slider.

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

[0013] As a further solution of the present invention: the insert block is engaged with the embedding cavity, the second screw rod extends into the embedding cavity, and the pitch of the second screw rod is equal to the pitch of the first screw rod.

[0014] Adopting the above technical solution: Compared with the prior art, the beneficial effects of the present invention are: The present invention uses two hot air blowers to connect the first air gathering shell and the second air gathering shell respectively, so that the sofa fabric in the first air gathering shell is pre-baked and the sofa fabric in the second air gathering shell is solidified. At the same time, the length of the sofa fabric in the first air gathering shell is twice the length of the sofa fabric in the second air gathering shell. According to the speed and time formula It can be seen that under the same moving speed, the ratio of the pre-baking time to the curing time is the ratio of the length of the pre-baking stage to the length of the curing stage. Therefore, the pre-baking time at this time is twice the curing time, which meets the time requirements in the background technology, so that the sofa fabric can pass through the pre-baking stage and the curing stage in the box in sequence, so that the pre-baking stage and the curing stage do not need to be carried out separately, thereby avoiding the sofa fabric from heating up again after cooling down, and gradually increasing the temperature during the entire drying process, thereby preventing fabric deformation or antibacterial agent decomposition caused by sudden heat, ensuring the quality of the sofa fabric, and simplifying the drying process at the same time, without the need to transfer the sofa fabric.

[0015] The present invention accelerates the rotation of the turbofan by the conveying roller, thereby increasing the air volume generated by the turbofan, and further increasing the air volume flowing into the closed cylinder through the duct. At this time, the air volume entering the closed cylinder is much greater than the air volume discharged by the one-way valve, which increases the air pressure between the piston rod and the piston ring, causing the piston rod to gradually shrink into the closed cylinder and continuously compress the air at the end of the closed cylinder. At this time, as the piston rod continues to move, the space between the piston rod and the piston ring increases, and the air pressure gradually decreases until the air pressure on both sides of the piston rod is re-balanced. At this time, the rotation speed of the turbofan and the conveying roller has reached the target value. It should be further explained that the above-mentioned piston rod shrinks. When the cam is in the sealed cylinder, the distance between the piston rod and the first screw rod continues to shorten, and the first screw rod is meshed and sleeved with the piston rod. At the same time, the first screw rod is fixed to the sealed cylinder, so that the piston rod rotates while shrinking and translating, thereby causing the piston rod to drive the strip to rotate, causing the auxiliary conveyor belt on the strip to rotate, and then causing the first screw rod on the auxiliary conveyor belt to rotate, and the first screw rod is meshed and sleeved with the slide, and the slide is slidably connected to the first slide groove and cannot rotate, so that the slide rod translates under the drive of the first screw rod, thereby causing the slide rod to drive the first adjusting roller away from the conveying roller, so that the length of the sofa fabric in the first air gathering shell increases, and the increase is , where V1 is the speed of the sofa after the speed is increased, V0 is the initial speed of the sofa, t is the pre-drying time of the sofa, which is a constant value. At this time, the moving distance between the carriage and the first adjustment roller is In summary, when the moving speed of the sofa increases, the pre-drying time can be kept constant, so that the moving speed of the sofa and the drying time are automatically matched. The moving speed of the sofa can be adjusted according to production needs, so that the pre-drying of the sofa can achieve the expected effect without adjusting the drying temperature. The pre-drying effect of the sofa is controllable, and there is no need to repeatedly adjust the temperature to avoid affecting the quality of the sofa. The drying device can adapt to diverse usage needs.

[0016] The present invention drives the second screw to rotate through the multi-stage gear, so that the slider on the second screw drives the second adjusting roller to translate, so that the second adjusting roller is away from the conveying roller. At the same time, the pitch of the second screw is the same as that of the first screw, so the displacement of the second adjusting roller is equal to that of the first adjusting roller. The increase in the sofa fabric in the second air gathering shell is equal to the displacement of the second adjusting roller. Therefore, the length of the sofa fabric in the first air gathering shell is still twice the length of the sofa fabric in the second air gathering shell, so that the change in the displacement speed of the sofa fabric does not affect the drying time, further ensuring the pre-baking effect and the curing effect. When the time ratio of the pre-baking stage to the curing stage changes, the second screw on the rotating rod is rotated, The second screw rod is extended into the embedding cavity, thereby pushing the embedding block to move toward the adjusting gear with reduced diameter, so that the diameter of the adjusting gear driven by the rotating rod is reduced, so the linear speed of the multi-stage gear is reduced, and the diameter of the multi-stage gear corresponding to the adjusting gear with reduced diameter is increased, so the angular velocity of the multi-stage gear is further reduced, and the number of revolutions of the second screw rod is reduced. Therefore, the length of the sofa fabric in the second wind gathering shell changes less, which indirectly changes the ratio of the sofa fabric length during pre-baking and curing, so that the ratio of pre-baking time to curing time can be adjusted, which can meet the use requirements of fabrics of different thicknesses or fabrics with different antibacterial agents, and thus can meet the adjustment of drying time.

In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0020] Example 1, please refer to Figure 1-Figure 3 、 Figure 6 and Figure 7 The present invention provides a technical solution: an antibacterial finishing and drying device for sofa fabrics, comprising a box body 1, a first air collecting shell 2 and a second air collecting shell 3 fixedly connected to the inner side wall of the box body 1, an inlet 4 opened at the top of the box body 1, an outlet 5 opened at the bottom of the box body 1, and a motor 6 installed on the side wall of the box body 1, one end of a conveying roller 7 fixedly connected to the output end of the motor 6, the other end of the conveying roller 7 fixedly connected to a main conveyor belt 8, and both ends of the main conveyor belt 8 are meshed and connected with transmission gears 9. A pressure roller 10 is fixed 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 box body 1, and a guide roller 13 is rotatably connected to the inner side wall of the box body 1. A slide 14 is slidably connected in the first slide groove 11, and a first adjusting roller 15 is rotatably connected to the side wall of the slide 14. A slider 16 is slidably connected in the second slide groove 12, and 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 box body 1.

[0021] See also Figure 6 There are two sliders 16 and two slides 14, and the two sliders 16 and the two slides 14 are symmetrically arranged with respect to the bisecting plane of the box body 1. The first adjusting roller 15 is located between the two slides 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.

[0022] See also Figure 2 、 Figure 3 and Figure 6 The length of the sofa in the first wind gathering shell 2 is twice the length of the sofa in the second wind gathering shell 3. Two hot air blowers 40 are provided, one hot air blower 40 is connected to the first wind gathering shell 2, and the other hot air blower 40 is connected to the second wind gathering shell 3.

[0023] Specifically, when the sofa fabric enters the box body 1, the hot air blower 40 and the motor 6 are started synchronously, so that the motor 6 drives the conveying roller 7 at the lower end to rotate, thereby rotating the main conveying belt 8 between the two conveying rollers 7, and the main conveying belt 8 drives the transmission gears 9 at both ends thereof to rotate, thereby rotating the pressure roller 10 on the transmission gear 9, and the rotation direction of the pressure roller 10 is opposite to that of the conveying roller 7, which can realize the transportation of the above-mentioned sofa fabric, and the two hot air blowers 40 are respectively connected to the first air gathering shell 2 and the second air gathering shell 3, so that the sofa fabric in the first air gathering shell 2 is pre-baked and the sofa fabric in the second air gathering shell 3 is cured. At the same time, the length of the sofa fabric in the first air gathering shell 2 is twice the length of the sofa fabric in the second air gathering shell 3. According to the speed and time formula It can be seen that under the same moving speed, the ratio of the pre-baking time to the curing time is the ratio of the length of the pre-baking stage to the length of the curing stage. Therefore, the pre-baking time at this time is twice the curing time, which meets the time requirements in the background technology, so that the sofa fabric can pass through the pre-baking stage and the curing stage in the box 1 in sequence, so that the pre-baking stage and the curing stage do not need to be carried out separately, thereby avoiding the sofa fabric from heating up again after cooling down, and gradually increasing the temperature during the entire drying process, thereby preventing fabric deformation or antibacterial agent decomposition caused by sudden heat, ensuring the quality of the sofa fabric, and simplifying the drying process at the same time, without the need to transfer the sofa fabric.

[0024] Example 2, please refer to Figure 2 and Figures 8-10 The present invention provides a technical solution: an antibacterial finishing and drying device for sofa fabrics, wherein a turbofan 18 is fixedly connected to the end of the conveying roller 7, and a fan casing 19 is provided on the outer outer surface of the turbofan 18. The outer surface of the fan casing 19 is connected to one end of a conduit 20, and the other end of the conduit 20 is connected to a sealed cylinder 21. A first screw rod 22 is fixedly connected to the end surface of the sealed cylinder 21, and a piston rod 23 is meshedly sleeved on the outer surface of the first screw rod 22. A piston ring 24 is slidably sleeved on the outer surface of the piston rod 23, and a molding 25 is embedded in the outer surface of the piston rod 23. One end of an auxiliary conveyor belt 26 is fixed to the side wall of the molding 25, and the other end of the auxiliary conveyor belt 26 is fixed to the first screw rod 27.

[0025] See also Figure 7-10The fan casing 19 is fixedly connected to the side wall of the casing 1, the turbofan 18 is rotatably connected to the side wall of the casing 1, the piston rod 23 is slidably connected 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 casing 1, a one-way valve is installed on the outer surface of the sealed cylinder 21, the auxiliary conveyor belt 26 is rotatably connected to the side wall of the casing 1, the first screw 27 is located in the first slide groove 11, and the first screw 27 is meshed and connected to the slide 14.

[0026] Specifically, in the process of accelerating the movement of the sofa fabric, according to the above principle, the rotation speed of the conveying roller 7 and the pressure roller 10 gradually increases, thereby gradually increasing the rotation speed of the turbofan 18 on the conveying roller 7, so that the air volume generated by the turbofan 18 gradually increases, and then the air volume flowing into the closed cylinder 21 from the duct 20 gradually increases. At this time, the air volume entering the closed cylinder 21 is much greater than the air volume discharged by the one-way valve, so that the air pressure between the piston rod 23 and the piston ring 24 increases, and the interface between the duct 20 and the closed cylinder 21 is located between the piston rod 23 and the piston ring 24. Therefore, the air introduced by the duct 20 is located between the piston rod 23 and the piston ring 24, that is, the right end of the closed cylinder 21. When the air pressure at the right end of the closed cylinder 21 increases, the pressure at its right end is greater than the air pressure at the left end, so that the high-pressure gas pushes the piston rod 23 to move from right to left, causing the piston rod 23 to gradually contract into the closed cylinder 21 and continuously compress the air at the end of the closed cylinder 21. At this time, as the piston rod 23 continues to move, the piston rod 23 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 balanced again. At this time, the speed of the turbofan 18 and the conveying roller 7 has reached the target value. It should be further explained that when the above-mentioned piston rod 23 is retracted into the sealed cylinder 21, the distance between the piston rod 23 and the first screw rod 22 continues to shorten, and the first screw rod 22 is meshed and sleeved with the piston rod 23. At the same time, the first screw rod 22 is fixed to the sealed cylinder 21, so that the piston rod 23 rotates while shrinking and translating, thereby causing the piston rod 23 to drive the strip 25 to rotate, causing the auxiliary conveyor belt 26 on the strip 25 to rotate, and then causing the first screw 27 on the auxiliary conveyor belt 26 to rotate, and the first screw 27 is meshed and sleeved with the slide 14. The slide 14 is slidably connected to the first slide groove 11 and cannot rotate, so that the slide 14 is driven by the first screw 27 to translate, so that the slide 14 drives the first adjusting roller 15 away from the conveying roller 7, so that the length of the sofa cloth in the first wind gathering shell 2 increases, and the increase is , where V1 is the speed of the sofa after the speed is increased, V0 is the initial speed of the sofa, t is the pre-drying time of the sofa, which is a constant value. At this time, the moving distance between the carriage 14 and the first adjustment roller 15 is In summary, when the moving speed of the sofa increases, the pre-drying time can be kept constant, so that the moving speed of the sofa and the drying time are automatically matched. The moving speed of the sofa can be adjusted according to production needs, so that the pre-drying of the sofa can achieve the expected effect without adjusting the drying temperature. The pre-drying effect of the sofa is controllable, and there is no need to repeatedly adjust the temperature to avoid affecting the quality of the sofa. The drying device can adapt to diverse usage needs.

[0027] Example 3, please refer to Figure 2-Figure 6 and Figure 8 The present invention provides a technical solution: an antibacterial finishing and drying device for sofa fabrics, wherein the end of the first screw 27 is fixedly connected to one end of the transmission chain 28, the other end of the transmission chain 28 is fixedly connected to one end of the rotating shaft 29, the other end of the rotating shaft 29 is rotatably connected to the bracket 30, and the outer surface of the rotating shaft 29 is fixedly connected to the driving gear 31, the outer surface of the driving gear 31 is meshedly connected to the driven gear 32, and a rotating rod 33 is fixed on the central axis of the driven gear 32. An embedding cavity 34 is opened in the rotating rod 33, and a second screw rod 35 is meshedly sleeved on the end surface of the rotating rod 33, and an insert block 36 is rotatably connected on the end surface of the second screw rod 35. An adjusting gear 37 is sleeved on the outer surface of the rotating rod 33, and the adjusting gear 37 is meshedly connected to the insert block 36, and the outer surface of the adjusting gear 37 is meshedly connected to the multi-stage gear 38, and a second screw 39 is fixed on the central axis of the multi-stage gear 38, and the second screw 39 is meshed and sleeved with the slider 16.

[0028] See also Figure 4 and Figure 6 The second screw 39 is located in the second slide groove 12, and the second screw 39 is rotatably connected to the side wall of the box body 1, the rotating rod 33 is rotatably connected to the side wall of the box body 1, the bracket 30 is fixed to the side wall of the box body 1, the diameter of the multi-stage gear 38 gradually increases, and the diameter of the adjusting gear 37 gradually decreases.

[0029] See also Figure 5 The insert block 36 is engaged with the embedding cavity 34 , the second screw rod 35 extends into the embedding cavity 34 , and the pitch of the second screw rod 39 is equal to the pitch of the first screw rod 27 .

[0030] 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, so that the driving gear 31 on the rotating shaft 29 drives the driven gear 32 to rotate, so that the rotating rod 33 on the driven gear 32 rotates, and the embedded cavity 34 on the rotating rod 33 is engaged with the embedded block 36, and at the same time, the embedded block 36 is engaged with the adjusting gear 37 of the corresponding diameter, so that the rotation of the rotating rod 33 can drive the adjusting gear 37 of the specific diameter to rotate, and the other adjusting gears 37 cannot be transmitted. At this time, the adjusting gear 37 of the specific diameter is The interlocking gear 37 drives the multi-stage gear 38 to rotate. The radius of the adjustment gear 37 of the specific diameter is equal to that of the corresponding multi-stage gear 38, so that the adjustment gear 37 and the multi-stage gear 38 rotate synchronously in the opposite direction, so that the second screw 39 on the multi-stage gear 38 rotates, so that the slider 16 on the second screw 39 drives the second adjustment roller 17 to translate, so that the second adjustment roller 17 is 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 adjustment roller 17 is equal to that of the first adjustment roller 15, and the second air collecting shell 38 rotates in the opposite direction. The increase in the amount of the sofa fabric in the first air gathering shell 2 is the displacement of the second adjusting roller 17. Therefore, the length of the sofa fabric in the first air gathering shell 2 is still twice the length of the sofa fabric in the second air gathering shell 3, so that the change in the speed of the sofa fabric does not affect the drying time, further ensuring the pre-baking effect and the curing effect. When the time ratio between the pre-baking stage and the curing stage changes, the second screw rod 35 on the rotating rod 33 is rotated so that the second screw rod 35 extends into the embedding cavity 34, thereby pushing the embedding block 36 to move toward the adjusting gear 37 with a reduced diameter, so that the adjusting gear 37 driven by the rotating rod 33 The diameter is reduced, so the linear speed of the multi-stage gear 38 is reduced, and the diameter of the multi-stage gear 38 corresponding to the adjusting gear 37 with a reduced diameter is increased, so the angular speed of the multi-stage gear 38 is further reduced, and the number of revolutions of the second screw 39 is reduced. Therefore, the length of the sofa fabric in the second air-collecting shell 3 changes less, which indirectly changes the ratio of the sofa fabric length during pre-baking and curing, so that the ratio of the pre-baking time to the curing time can be adjusted, which can meet the use requirements of fabrics of different thicknesses or fabrics with different antibacterial agents, and thus can meet the adjustment of the drying time.

[0031] The working principle and use process of the present invention are as follows: when the sofa cloth needs to be dried, the sofa cloth adsorbed with the antibacterial agent is put into the inlet 4 on the box body 1, so that the sofa cloth passes through the first adjusting roller 15, the guide roller 13 and the second adjusting roller 17 in sequence, and continues to move under the drive of the conveying roller 7 and the pressure roller 10, and is finally discharged from the outlet 5 to complete the drying of the sofa cloth. During the above process, after the sofa cloth enters the box body 1, the hot air blower 40 and the motor 6 are started synchronously, so that the motor 6 drives the conveying roller 7 at the lower end to rotate, thereby making the main conveying roller 7 between the two conveying rollers 7 rotate. The belt 8 rotates, so that the main conveyor belt 8 drives the transmission gears 9 at both ends thereof to rotate, and then the pressure roller 10 on the transmission gear 9 rotates, and the rotation direction of the pressure roller 10 is opposite to that of the conveying roller 7, so as to realize the conveying of the above-mentioned sofa fabrics, and the two hot air blowers 40 are connected to the first air gathering shell 2 and the second air gathering shell 3 respectively, so that the sofa fabrics in the first air gathering shell 2 are pre-baked and the sofa fabrics in the second air gathering shell 3 are cured. At the same time, the length of the sofa fabrics in the first air gathering shell 2 is twice the length of the sofa fabrics in the second air gathering shell 3. According to the speed and time formula It can be seen that, under the same moving speed, the ratio of the pre-baking time to the curing time is the ratio of the length of the pre-baking stage to the length of the curing stage. Therefore, the pre-baking time at this time is twice the curing time, which meets the time requirement in the background technology, so that the sofa fabric can pass through the pre-baking stage and the curing stage in sequence in the box 1, so that the pre-baking stage and the curing stage do not need to be carried out separately, thereby avoiding the sofa fabric from being heated up again after cooling down, and gradually increasing the temperature during the entire drying process, thereby preventing the fabric deformation or antibacterial agent decomposition caused by sudden heat, ensuring the quality of the sofa fabric, and simplifying the drying process at the same time, without the need to transfer the sofa fabric; When the speed of the sofa sheet needs to be accelerated, according to the above principle, the rotation speed of the conveying roller 7 and the pressure roller 10 increases, thereby increasing the rotation speed of the turbofan 18 on the conveying roller 7, increasing the air volume generated by the turbofan 18, and then increasing the air volume flowing into the closed cylinder 21 from the duct 20. At this time, the air volume entering the closed cylinder 21 is much greater than the air volume discharged by the one-way valve, which increases the air pressure between the piston rod 23 and the piston ring 24, causing the piston rod 23 to gradually shrink into the closed cylinder 21 and continuously compress the air at the end of the closed cylinder 21. At this time, 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 time, the rotation speed of the turbofan 18 and the conveying roller 7 has reached the target value, which requires further explanation. The thing is, when the piston rod 23 is retracted into the sealed tube 21, the distance between the piston rod 23 and the first screw rod 22 continues to shorten, and the first screw rod 22 is meshed and sleeved with the piston rod 23. At the same time, the first screw rod 22 is fixed to the sealed tube 21, so that the piston rod 23 rotates while shrinking and moving, so that the piston rod 23 drives the strip 25 to rotate, so that the auxiliary conveyor belt 26 on the strip 25 rotates, and then the first screw rod 27 on the auxiliary conveyor belt 26 rotates, and the first screw rod 27 is meshed and sleeved with the slide 14, and the slide 14 is slidably connected to the first slide groove 11 and cannot rotate, so that the slide 14 is driven by the first screw rod 27 to move horizontally, so that the slide 14 drives the first adjusting roller 15 away from the conveying roller 7, so that the length of the sofa fabric in the first wind gathering shell 2 increases, and the increase is , where V1 is the speed of the sofa after the speed is increased, V0 is the initial speed of the sofa, t is the pre-drying time of the sofa, which is a constant value. At this time, the moving distance between the carriage 14 and the first adjustment roller 15 is In summary, when the moving speed of the sofa increases, the pre-drying time can be kept constant, so that the moving speed of the sofa and the drying time are automatically matched. The moving speed of the sofa can be adjusted according to production needs, so that the pre-drying of the sofa can achieve the expected effect without adjusting the drying temperature. The pre-drying effect of the sofa is controllable, and there is no need to repeatedly adjust the temperature to avoid affecting the quality of the sofa. The drying device can adapt to diverse usage needs. As the first screw 27 rotates, the transmission chain 28 on the first screw 27 synchronously drives the rotating shaft 29 to rotate, so that the driving gear 31 on the rotating shaft 29 drives the driven gear 32 to rotate, so that the rotating rod 33 on the driven gear 32 rotates, and the embedded cavity 34 on the rotating rod 33 is engaged with the embedded block 36, and at the same time, the embedded block 36 is engaged with the adjusting gear 37 of the corresponding diameter, so that the rotation of the rotating rod 33 can drive the adjusting gear 37 of a specific diameter to rotate, and the other adjusting gears 37 cannot be driven. At this time, the adjusting gear 37 of a specific diameter is engaged. The multi-stage gear 38 is driven to rotate. The radius of the adjustment gear 37 of the specific diameter is equal to that of the corresponding multi-stage gear 38, so that the adjustment gear 37 and the multi-stage gear 38 rotate synchronously in the opposite direction, so that the second screw 39 on the multi-stage gear 38 rotates, so that the slider 16 on the second screw 39 drives the second adjustment roller 17 to translate, so that the second adjustment roller 17 is 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 adjustment roller 17 is equal to that of the first adjustment roller 15, and the sofa fabric in the second air collecting shell 3 is The increase is the displacement of the second adjusting roller 17, so the length of the sofa fabric in the first air gathering shell 2 is still twice the length of the sofa fabric in the second air gathering shell 3, so that the change in the movement speed of the sofa fabric does not affect the drying time, further ensuring the pre-baking effect and the curing effect. When the time ratio between the pre-baking stage and the curing stage changes, the second screw rod 35 on the rotating rod 33 is rotated so that the second screw rod 35 extends into the embedding cavity 34, thereby pushing the embedding block 36 to move toward the adjusting gear 37 with a reduced diameter, so that the diameter of the adjusting gear 37 driven by the rotating rod 33 is reduced. Therefore, the linear velocity of the multi-stage gear 38 decreases, and the diameter of the multi-stage gear 38 corresponding to the adjusting gear 37 with a reduced diameter increases, so the angular velocity of the multi-stage gear 38 is further reduced, and the number of revolutions of the second screw 39 is reduced. Therefore, the length of the sofa fabric in the second wind gathering shell 3 changes less, which indirectly changes the ratio of the length of the sofa fabric during pre-baking and curing, so that the ratio of the pre-baking time to the curing time can be adjusted, which can meet the use requirements of fabrics of different thicknesses or fabrics with different antibacterial agents, and thus can meet the adjustment of the drying time to complete the operation.
