Detailed implementation manner

[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0035] As Figures 1 to 8 shown;

[0036] A cloth drying device includes a machine body 1, a feeding port 2, a discharging port 3, and a fan 4. A machine door 19 is provided on the outer wall of the machine body 1. The feeding port 2 is opened on the lower left outer wall of the machine body 1, and the discharging port 3 is opened on the upper right outer wall of the machine body 1. The fan 4 is fixedly connected to the outer wall of the machine body 1. It also includes;

[0037] A fixed box 5, the fixed box 5 is evenly fixedly connected to the inner wall of the machine body 1. The inside of the fixed box 5 is communicated with the air outlet of the fan 4 through a pipeline, and the inside of the fixed box 5 is communicated through a pipeline;

[0038] A drying roller 7, one end of the drying roller 7 is rotatably connected to the outer wall of the fixed box 5. The hollow part inside the drying roller 7 is communicated with the inside of the fixed box 5, and the end of the drying roller 7 far from the fixed box 5 is rotatably connected to the inner wall of the machine body 1; the drying rollers 7 are arranged in a staggered manner up and down, so that when the cloth passes through the drying rollers 7, it has an S-shaped path, which is conducive to the full drying of the cloth;

[0039] A motor 9, the motor 9 is fixedly connected to the outer wall of the machine body 1;

[0040] A support frame 10, the support frame 10 is fixedly connected to the outer wall of the machine body 1 below the discharging port 3 and the feeding port 2;

[0041] A material roller 11, the material roller 11 is placed on the upper end surface of the support frame 10 and close to the feeding port 2;

[0042] A finished product roller 12, the finished product roller 12 is placed on the upper end surface of the support frame 10 and close to the discharging port 3. The rotating shaft of the finished product roller 12 is power-connected to the rotating shaft of the motor 9 through a belt;

[0043] During use, the staff member opens the door 19 on the machine body 1, pulls the fabric to be dried on the material roller 11 into the machine body 1 from the feed inlet 2, then passes the fabric through the drying rollers 7 in sequence, spreads the fabric evenly on the surface of the drying rollers 7, and then pulls it out from the discharge outlet 3 and winds it around the surface of the finished product roller 12. Start the fan 4. When the fan 4 is running, the gas is blown into the fixed box 5 from the air inlet of the fan 4 through the pipeline 17. The electric heating wire 6 in the fixed box 5 heats the air into hot air. The hot air reaches the inside of the drying roller 7 from the fixed box 5, and then is discharged outward through the heat dissipation openings 8 evenly arranged on the drying roller 7 to preheat the inside of the machine body 1. After the preheating is completed, start the motor 9. The motor 9 drives the finished product roller 12 to rotate to wind up the fabric. Under the pulling of the finished product roller 12, the fabric passes through the drying rollers 7 in sequence at a constant speed. The fabric passing through the drying rollers 7 will be dried by the hot air discharged from the heat dissipation openings 8. The upper and lower layers of drying rollers 7 are staggered in design, so that when the fabric passes through the two drying rollers 7, the fabric is always in a taut state due to the tension and fits on the surface of the drying rollers 7, thereby reducing the probability of the fabric wrinkling due to dehydration. The finished product roller 12 rotates continuously to pull the dried fabric and wind up the dried fabric. After the winding is completed, the staff member removes the fabric wound on the finished product roller 12, and then winds the next batch of fabric on the finished product roller 12 to continue the drying work, so as to prevent the fabric from being easily wrinkled due to dehydration after drying, resulting in defects in the dried fabric and inability to carry out the next processing, increasing the production cost. At the same time, the fabric drying and winding work are carried out synchronously, reducing the labor cost and improving the processing efficiency.

[0044] As a specific embodiment of the present invention, as Figures 1 to 2 shown, the upper end surface of the machine body 1 is conical, and an air outlet hole 13 is opened at the top. The inner wall of the upper side of the machine body 1 is fixedly connected with a water tank 14. The outer wall of the machine body 1 is fixedly connected with a water outlet pipe 15, and the water outlet pipe 15 penetrates through the machine body 1 to the inside of the water tank 14;

[0045] During use, when the hot air discharged from the drying roller 7 dries the fabric, the moisture in the fabric evaporates. The evaporated moisture will float upward. When it floats to the top of the machine body 1, because the upper wall of the machine body 1 is conical, it can guide the upward floating water vapor, so that it floats to the air outlet hole 13 along the upper arc wall inside the machine body 1, greatly increasing the effect of discharging water vapor from the air outlet hole 13. At the same time, part of the water vapor that has not been discharged from the machine body 1 condenses into water droplets on the inner upper wall of the machine body 1. The condensed water droplets will flow downward along the arc upper wall inside the machine body 1 due to gravity, and then flow into the water tank 14 fixedly connected to the inner wall of the machine body 1, thereby preventing the water droplets from dripping onto the fabric. To prevent excessive water vapor in the machine body 1 from dripping onto the fabric after long-term drying of the fabric, the designed water outlet pipe 15 will discharge the water in the water tank 14 from the water outlet pipe 15 fixedly connected to the outer wall of the machine body 1 out of the machine body 1.

[0046] As a specific embodiment of the present invention, as Figure 3 and Figure 4 shown, the drying roller 7 is in an olive shape with a higher middle part and lower both sides, and circular ring baffles 16 are symmetrically and fixedly connected to both ends of the drying roller 7.

[0047] The circular ring baffles 16 at both ends of the drying roller 7 can intercept and block the fabric when the drying roller 7 pulls the fabric, preventing the fabric from running off on the drying roller 7. Using a drying roller 7 with a circular cross-section makes the middle part of the fabric propped up and not easily deformed in the width direction when the fabric is dried by the hot air blown out from the heat dissipation openings 8 on the drying roller 7.

[0048] As another specific embodiment of the present invention, as Figure 4 and Figure 5 shown, the cross-section of the axis of the drying roller 7 is a regular polygon. This design method can intermittently pull the fabric in the length direction, avoiding both the shrinkage of the fabric after drying and the situation of excessive pulling force on the fabric that may cause damage to the fabric.

[0049] As a specific embodiment of the present invention, as Figure 3 and Figure 4 shown, heat dissipation openings 8 are evenly arranged on the outer wall of the drying roller 7, and the aperture of the heat dissipation openings 8 gradually decreases from the end close to the inside of the drying roller 7 to the outside. The horizontal cross-section of the heat dissipation openings 8 is circular, and a plurality of the heat dissipation openings 8 are arrayed on the surface of the drying roller 7. According to the Venturi effect, when gas passes through a narrow area, the flow rate will increase. The design that the aperture of the heat dissipation openings 8 gradually decreases from the end close to the inside of the drying roller 7 to the outside can make the flow rate of the hot air increase and the wind force become larger when the heat dissipation openings 8 discharge hot air to dry the fabric, improving the drying efficiency.

[0050] As another specific embodiment of the present invention, as Figure 6 shown, heat dissipation openings 8 are evenly arranged on the outer wall of the drying roller 7, and the aperture of the heat dissipation openings 8 gradually decreases from the end close to the inside of the drying roller 7 to the outside. The horizontal cross-section of the heat dissipation openings 8 is rectangular, and a plurality of the heat dissipation openings 8 are arrayed on the surface of the drying roller 7. When in use, since the cross-section of the heat dissipation openings 8 is rectangular, the air output is larger, and the contact area between the hot air and the fabric is also larger, which is more conducive to drying the fabric.

[0051] As a specific embodiment of the present invention, as Figures 1 to 2As shown in the figure, a blower 4 is fixedly connected to the outer wall on the right side of the machine body 1. The air inlet of the blower 4 faces downward, and directly below the air inlet is the dried fabric. A filter screen 18 is fixedly connected to the air inlet of the blower 4. The distance between the filter screen 18 and the fabric when they are horizontally placed is 10 - 20 cm. The lower surface of the filter screen 18 is polished to prevent the fabric from being scratched when it contacts the lower surface of the filter screen 18. During use, the blower 4 sucks in air from the air inlet. Since the dried fabric is located below the air inlet, the negative pressure at the air inlet will adsorb the fabric, causing the fabric to move closer to the air inlet and even slide and adsorb on the lower surface of the filter screen 18. The advantages of this design are as follows: on the one hand, it can cool the dried fabric that still has heat, facilitating the winding of the fabric; on the other hand, it can preheat the air at the air inlet, realizing partial reuse of heat and solving energy problems; on the other hand, the adsorption of the fabric at the air inlet can elastically tension the fabric, which can cooperate with the drying roller 7 to tension the fabric, thus avoiding the shrinkage of the fabric. Especially when the cross-section of the drying roller 7 is a regular polygon, the adjustable distance between the fabric and the filter screen 18 can be used to adjust the tension of the fabric.

[0052] The specific working process is as follows:

[0053] During use, the staff opens the door 19 on the machine body 1, pulls the fabric to be dried on the material roller 11 into the machine body 1 from the feeding port 2, then passes the fabric through the drying roller 7 in sequence, spreads the fabric evenly on the surface of the drying roller 7, and then pulls it out from the discharging port 3 and winds it around the surface of the finished product roller 12. When the blower 4 operates, the gas is blown into the fixed box 5 from the air inlet through the pipeline 17. The electric heating wire 6 in the fixed box 5 heats the air into hot air. The hot air reaches the inside of the drying roller 7 from the fixed box 5, and then is discharged outward through the heat dissipation openings 8 evenly arranged on the drying roller 7 to preheat the inside of the machine body 1. After the preheating is completed, the motor 9 is started. The motor 9 drives the finished product roller 12 to rotate to wind the fabric. Under the pulling of the finished product roller 12, the fabric passes through the drying roller 7 at a constant speed in sequence. The fabric passing through the drying roller 7 will be dried by the hot air discharged from the heat dissipation openings 8. The staggered design of the upper and lower drying rollers 7 makes the fabric in a tight state at all times due to the tension force and fits on the surface of the drying roller 7 when passing through the two drying rollers 7, thus reducing the probability of the fabric wrinkling due to dehydration. The finished product roller 12 rotates continuously to pull the dried fabric and wind the dried fabric. After the winding is completed, the staff removes the fabric-wound finished product roller 12, and then winds the next batch of fabric around the finished product roller 12 to continue the drying work, thus avoiding wrinkles in the fabric after drying due to dehydration, resulting in defects in the dried fabric. At the same time, the fabric drying and winding work are carried out simultaneously, reducing the labor cost and improving the processing efficiency.

Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
