Description

Technical Field

[0001] The utility model relates to the technical field, in particular to equipment for drying polyester filaments. Background Art

[0002] Polyester is a synthetic fiber made of organic dibasic acid and diol through chemical polycondensation. It is a kind of polymer compound. Its invention can be traced back to the 1930s. Today, it is the most important type of synthetic fiber. Polyester has many advantages. First, it has excellent wrinkle resistance and shape retention. The clothes made of it are not easy to wrinkle during wearing and can maintain the original shape of the clothes. Secondly, polyester fiber has high strength and elastic recovery ability, which makes the woven fabric strong and durable, and can quickly restore to its original shape. In addition, polyester fiber also has the characteristics of wear resistance and non-stick hair, making the fabric look neater.

[0003] At present, polyester needs to be dried during the production process. The existing polyester drying process has the following defects: hot air dries the polyester on a material placement plate from top to bottom, resulting in a large difference in the drying degree between the upper and lower surfaces of the polyester, resulting in a low utilization rate of heat energy.

[0012] Preferably, the driving source is configured as a driving motor or a driving motor.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model uses the air outlet plates on the sealing plates on both sides of the discharge port to discharge air to dry the two sides of the polyester filaments simultaneously, thereby avoiding the adverse effects caused by the large difference in drying degree between the two sides of the polyester filaments. At the same time, the sealing plates on both sides of the discharge port isolate a temporary small drying area inside the oven, temporarily gather the air blown out by the air outlet plates, and continue the drying work, thereby improving the utilization rate of heat energy;

[0015] 2. The utility model dries the polyester filaments obliquely downward, and while drying both sides of the polyester filaments simultaneously, the polyester filaments can be sent to the pressing roller for rolling by the force of wind, thereby improving practicality.

[0022] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0023] like Figure 1 As shown, the polyester filament drying device of the utility model includes an oven 1, and the top and bottom of the oven 1 are respectively provided with a feed port 5 and a discharge port 9 for the polyester filaments to pass through. The width of the feed port 5 is greater than the thickness of the polyester filaments by 1 mm, and the width of the discharge port 9 is set to 20 mm. The narrow feed port 5 ensures that hot air will not be lost quickly through the feed port 5, thereby ensuring that the hot air can continue to dry the polyester filaments, thereby improving the utilization rate of thermal energy, and the wider discharge port 9 ensures that the polyester filaments can be discharged from the discharge port 9 stably and quickly, thereby improving work efficiency.

[0024] Embodiment 1

[0025] The top of the oven 1 is symmetrically provided with sealing plates 7, and the two sealing plates 7 are respectively located on both sides of the discharge port 9. Figure 2 As shown, the sealing plates 7 are vertically fixed on the top of the oven 1, and the facing surfaces of the two sealing plates 7 are provided with air outlet plates 8, and the air outlet plates 8 are arranged parallel to the sealing plates 7. The air is discharged vertically by the air outlet plates 8 on the sealing plates 7 on both sides of the discharge port 9 to dry the two sides of the polyester filaments synchronously, thereby avoiding the adverse effects caused by the large difference in drying degree on the two sides of the polyester filaments. At the same time, a temporary small space drying area is isolated inside the oven 1 through the sealing plates 7 on both sides of the discharge port 9, and the wind blown out by the air outlet plates 8 is temporarily gathered to continue the drying work, thereby improving the utilization rate of thermal energy.

[0026] Embodiment 2

[0027] The top of the oven 1 is symmetrically provided with sealing plates 7, and the two sealing plates 7 are respectively located on both sides of the discharge port 9.

The facing surfaces of the two sealing plates 7 are provided with air outlet plates 8, and the air outlet plates 8 are arranged parallel to the sealing plates 7. The air outlet plates 8 are tilted downward to dry the polyester filaments through the tilted arrangement. While the two sides of the polyester filaments are dried synchronously, a guiding function is also realized, and the polyester filaments are transported to the discharge port 9 through the action of wind, thereby improving practicality.

[0028] The bottom of the sealing plate 7 is rotatably connected to the pressure roller 6, and the sealing plate 7 is rotatably connected to the pressure roller 6 at the highest point. The ends of the pressure roller 6 are fixedly provided with a driving gear 2 that penetrates the oven 1, and the two driving gears 2 are meshed and connected. Figure 4 As shown, a support plate 4 is fixed on the oven 1, and a driving source 3 is fixed on the support plate 4. The driving source 3 is configured as a driving motor, and the output end of the driving source 3 is transmission-connected to one of the driving gears 2. The driving source 3 drives one of the driving gears 2 to rotate and then drives, and the two driving gears 2 are driven to rotate synchronously through the meshing connection between the two driving gears 2, and then the two pressing rollers 6 are driven to rotate in the opposite direction through the driving mechanism composed of the driving source 3 and the driving gears 2. The reverse movement of the two pressing rollers 6 can, on the one hand, transport the polyester filaments to the discharge port 9, and on the other hand, crush the polyester filaments, thereby improving the drying efficiency and ensuring the softness of the polyester filaments.
