Description

Technical Field

[0001] This utility model relates to the technical field of nonwoven fabric production equipment, specifically a dryer for nonwoven fabric production. Background Technology

[0002] Drying is a crucial step in the production of nonwoven fabrics.

[0003] Traditional drying equipment often suffers from low drying efficiency, high energy consumption, and uneven drying, which directly affects the production quality and efficiency of nonwoven fabrics. Existing nonwoven fabric dryers mostly employ hot air circulation drying, blowing hot air into the dryer chamber to dry the nonwoven fabric. However, this method often fails to ensure uniform heating of all parts of the nonwoven fabric, resulting in unsatisfactory drying effects. Furthermore, traditional dryers are inadequate in adjusting the tension of the nonwoven fabric and in pressing and squeezing out water, further impacting drying efficiency and quality. Therefore, we propose a new type of dryer for nonwoven fabric production. Utility Model Content

[0004] The purpose of this invention is to provide a dryer for nonwoven fabric production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dryer for nonwoven fabric production includes a dryer box. A drive roller is rotatably mounted on the lower left side inside the dryer box. Pressing rollers are slidably mounted on the front and rear side walls of the dryer box above the drive roller via sliders. A sliding rod is mounted on the front outer wall of the dryer box via a mounting plate. A through hole is provided through the front slider, and the front slider is slidably connected to the sliding rod. A threaded rod is rotatably mounted on the rear mounting plate, passing through the slider and threadedly connected to it. A drive gear is rotatably mounted on the front outer wall of the dryer box via a mounting bracket. A driven gear is connected to the drive roller via a key, and the driven gear meshes with the drive gear. Several guide rollers are evenly arranged inside the dryer box. Two air jet plates are also provided inside the dryer box. A drain valve is also provided on the dryer box.

[0007] As a further embodiment of this utility model: a worm gear is also provided on the threaded rod by a key connection, and a worm is provided on the front mounting plate by a mounting shell, with the worm and the worm gear meshing with each other.

[0008] As a further improvement of this utility model: a telescopic rod is also provided on the inner wall of the dryer box via a fixed plate, and a tension roller is provided at the end of the telescopic arm of the telescopic rod via a bearing seat.

[0009] As a further improvement of this utility model, a handle is provided at the outer end of the worm gear.

[0010] As a further improvement of this utility model: a return spring is sleeved on the outer side of the telescopic rod, one end of the return spring is connected to the bearing with a seat, and the other end of the return spring is connected to the fixing plate.

[0011] As a further improvement of this utility model: a motor is also provided on the mounting bracket, and the power output shaft of the motor is connected to the rotating shaft of the drive gear through a coupling.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The meshing transmission between the drive roller and the driven gear, and the drive gear, ensures the smooth transport of non-woven fabric. At the same time, the setting of the pressure roller further squeezes the moisture on the non-woven fabric, reducing the burden on subsequent drying. The air jet plates are distributed at the top and bottom, which can evenly spray hot air into the dryer box, achieving rapid and uniform drying of non-woven fabric and greatly improving drying efficiency.

[0014] 2. The threaded connection between the threaded rod and the slider, along with the worm gear, allows for flexible adjustment of the height of the pressing roller to meet the production needs of nonwoven fabrics of different thicknesses and specifications.

[0021] Example

[0022] Please see Figures 1-4 In this embodiment of the present invention, a dryer for nonwoven fabric production includes a dryer box 1. An active roller 5 is rotatably mounted on the lower left side inside the dryer box 1. A pressing roller 4 is slidably mounted on the front and rear side walls of the dryer box 1 above the active roller 5 via a slider. A sliding rod 3 is mounted on the front outer wall of the dryer box 1 via a mounting plate 2. A through hole is provided through the front slider, and the front slider is slidably connected to the sliding rod 3. A threaded rod 7 is rotatably mounted on the rear mounting plate 2, threaded through the slider and connected to the remaining sliders. Rotating the threaded rod 7 drives the pressing roller 4 to move up and down. In actual use, when drying the nonwoven fabric, the pressing roller 4 and the active roller 5 can squeeze out the residual moisture on the nonwoven fabric, thereby reducing the subsequent drying time and improving the working efficiency of the dryer to a certain extent. The dryer box 1 is also equipped with a drain valve, which facilitates the discharge of squeezed-out water, thus ensuring the efficiency of the dryer box 1.

[0023] A worm gear 9 is also connected to the threaded rod 7 via a key. A worm 10 is mounted on the front mounting plate 2 via a mounting shell 8. The worm 10 and the worm gear 9 mesh with each other. Rotating the worm 10 will drive the threaded rod 7 to rotate through the worm gear 9, thereby adjusting the distance between the pressing roller 4 and the drive roller 5. This allows for better water squeezing of the nonwoven fabric, ensuring the subsequent drying quality. Furthermore, the worm gear 9 and worm 10 have a self-locking function, which restricts their adjusted position, ensuring the water squeezing efficiency of the drive roller 5 and the pressing roller 4 on the nonwoven fabric. A handle 11 is provided at the outer end of the worm 10. Rotating the handle 11 will drive the worm 10 to rotate, thereby adjusting the position of the pressing roller 4.

[0024] A drive gear 13 is rotatably mounted on the front outer wall of the dryer box 1 via a mounting bracket. A driven gear 12 is connected to the drive roller 5 via a key. The driven gear 12 meshes with the drive gear 13. At this time, the drive roller 5 can be rotated by the drive gear 13 and the driven gear 12, thereby squeezing water from the non-woven fabric. A motor 14 is also mounted on the mounting bracket. The power output shaft of the motor 14 is connected to the rotating shaft of the drive gear 13 via a coupling. At this time, the motor 14 can drive the drive gear 13 to rotate.

[0025] The drying chamber 1 is also equipped with several guide rollers 15 evenly arranged inside. Under the action of the guide rollers 15, it is convenient to draw the non-woven fabric out from the drying chamber 1. The drying chamber 1 is also equipped with two air jet plates 6, which can input hot air into the drying chamber 1 under the action of the air jet plates 6, thereby drying the non-woven fabric.

[0026] The inner wall of the drying chamber 1 is also equipped with a telescopic rod 17 via a fixed plate 16. The telescopic arm of the telescopic rod 17 is equipped with a tension roller 19 via a bearing seat. Under the action of the tension roller 19, the non-woven fabric can always be kept in a taut state, thereby ensuring its drying efficiency. A return spring 18 is sleeved on the outside of the telescopic rod 17. One end of the return spring 18 is connected to the bearing seat, and the other end of the return spring 18 is connected to the fixed plate 16. Under the action of the return spring 18, the tensioning efficiency of the tension roller 19 is ensured, thereby ensuring the drying quality of the drying chamber 1.

[0027] In actual use, the nonwoven fabric is passed through the dryer chamber 1, passing sequentially over the drive roller 5, the pressing roller 4, and several guide rollers 15. The motor 14 is started, and its power output shaft drives the drive gear 13 to rotate through the coupling. The drive gear 13 meshes with the driven gear 12, thereby driving the drive roller 5 to rotate. The nonwoven fabric moves under the traction of the drive roller 5. The handle 11 is rotated, and the handle 11 drives the worm gear 10 to rotate inside the mounting housing 8. The worm gear 10 meshes with the worm wheel 9, and the rotation of the worm wheel 9 drives the threaded rod 7 to rotate. The threaded rod 7 is threadedly connected to the slider, driving the slider and the pressing roller 4 to move along the slide rod 3. The sliding mechanism adjusts the distance between the pressing roller 4 and the driving roller 5 to accommodate the water squeezing requirements of nonwoven fabrics of different thicknesses. The self-locking function of the worm gear ensures stable positioning after adjustment. When the nonwoven fabric passes between the pressing roller 4 and the driving roller 5, residual moisture is squeezed out, reducing drying time. Subsequently, the nonwoven fabric passes through the air jet plate 6, which sprays hot air to dry the nonwoven fabric. The tensioning roller 19, connected to the telescopic rod 17 via the return spring 18, always keeps the nonwoven fabric in a taut state, improving drying efficiency. The return spring 18 provides continuous tension to the tensioning roller 19, ensuring drying quality.
