[0024] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0025] Reference Figures 1-5 As shown, an engineering plastic filament drawing water-cooled drying device 4 of this embodiment includes a water-cooling tank 1 and cooling water disposed in the water-cooling tank 1. A guide frame 2 is provided on the water-cooling tank and is located above the water. A retainer 3 is provided inside the water-cooling tank and is located underwater. The plastic filament is connected to the guide frame 2 and the retainer 3. A drying device 4 is provided on the water-cooling tank and is located in the forward direction of the plastic filament. The drying device 4 includes:

[0026] The drying oven 41 is fixedly installed on the upper side of the water cooling tank 1, located between the guide frame 2 and the external cutting mechanism;

[0027] The scraping mechanism 42 is installed inside the drying chamber 41. The scraping mechanism 42 is located on the side near the guide frame 2. The scraping mechanism 42 contacts the plastic filament and scrapes off the cooling water on the plastic filament.

[0028] Wiping mechanism 43 is installed inside drying box 41. Wiping mechanism 43 is arranged adjacent to scraping mechanism 42. Wiping mechanism 43 is used to wipe the cooling water on plastic filament.

[0029] A drying mechanism 44 is installed inside a drying chamber 41. The drying mechanism 44 is arranged adjacent to the wiping mechanism 43. The drying mechanism 44 is used to dry the cooling water on the plastic filament.

[0030] With the above technical solution, the guide frame 2 and the retainer 3 are equipped with rollers. When the equipment is running, the guide frame 2 and the retainer 3 guide the position of the plastic filament, so that the plastic filament first moves downward into the cooling water, and then leaves the cooling water and enters the drying chamber 41 for drying.

[0031] The plastic filaments entering the drying chamber 41 first pass through the scraping mechanism 42, which scrapes off most of the cooling water from the surface of the plastic filaments. Then, the plastic filaments pass through the wiping mechanism 43, which wipes off a small amount of cooling water from the surface of the plastic filaments. Then, the plastic filaments pass through the drying mechanism 44, which dries the surface of the plastic filaments. Finally, the plastic filaments leave the drying chamber 41 and move forward to the external cutting mechanism for cutting.

[0032] Before cutting the plastic filaments, the surface of the plastic filaments is dried so that the cut plastic filaments are dry and no further drying is required, thereby improving production efficiency.

[0033] As an improved specific implementation, the scraping mechanism 42 includes an upper scraper 421 and a lower scraper 422, the upper scraper 421 and the lower scraper 422 are spaced apart, the upper scraper 421 is located between the lower scraper 422 and the guide frame 2, the upper scraper 421 is provided with an upper scraping groove 4211, and the lower scraper 422 is provided with a lower scraping groove 4221, the upper scraping groove 4211 and the lower scraping groove 4221 are used to accommodate plastic filaments.

[0034] Through the above technical solution, the upper scraper groove 4211 and the lower scraper groove 4221 wrap around the plastic filaments; the advancing plastic filaments first contact the upper scraper 421 and then the lower scraper 422, which can scrape off most of the cooling water adhering to the surface of the plastic filaments, and the scraping process is stable. After the cooling water on the surface of the plastic filaments is reduced, it is easier to wipe subsequently, reducing wiping pressure, lowering drying pressure, and thus reducing energy consumption.

[0035] As an improved specific implementation, the upper scraper 421 and the lower scraper 422 are arranged at an angle, the upper scraper 421 is provided with a downwardly inclined dripping part 4212, and the lower scraper 422 is provided with a guide groove 4222.

[0036] Through the above technical solution, the cooling water scraped off by the upper scraper 421 flows along the dripping part 4212 and then drips downwards; the cooling water scraped off by the lower scraper 422 flows downwards along the guide groove 4222, avoiding the accumulation of cooling water between the upper scraper 421 and the plastic filaments, and between the lower scraper 422 and the plastic filaments, so that the cooling water is scraped off more thoroughly, thereby reducing the power of the subsequent drying mechanism 44 and reducing energy consumption.

[0037] As one specific embodiment of the improvement, the wiping mechanism 43 includes:

[0038] A wiping motor 431 is fixedly mounted on a drying oven 41, and a drive wheel 432 is provided on the wiping motor 431;

[0039] Wiping cloth 433 is arranged in a continuous ring and is sleeved on the drive wheel 432 and the thin plastic line.

[0040] With the above technical solution, when the wiping mechanism 43 is running, the wiping motor 431 runs and drives the drive wheel 432 to rotate, which in turn drives the wiping cloth 433 to rotate, wiping the plastic filaments and further reducing the cooling water adhering to the plastic filaments.

[0041] As one specific embodiment of the improvement, the wiping mechanism 43 has two sets, which are respectively arranged on both sides of the plastic thread.

[0042] With the above technical solution, wiping cloths 433 are set on both sides to wipe the plastic filaments. There are no dead corners during the wiping process, and the plastic filaments are evenly stressed on both sides, which can stably transmit forward and improve the stability of the production process.

[0043] As an improved specific implementation, the drying mechanism 44 includes a drying channel 441, a heating wire 442, and a blower 443. The drying channel 441 is installed on and connected to the drying chamber 41. The heating wire 442 is installed inside the drying channel 441. The blower 443 is installed at the end of the drying channel 441 and connected to the outside.

[0044] With the above technical solution, when the drying mechanism 44 is running, the heating wire 442 is energized and heats up, and the blower 443 runs, blowing the external airflow into the drying channel 441, then carrying the heat, and then entering the drying box 41 to dry the moisture on the surface of the plastic filaments.

[0045] Specifically, the drying channel 441 is located on the side of the drying chamber 41 facing the external cutting mechanism. The airflow from the blower 443 is opposite to the direction of the plastic filament's movement. After the drying airflow passes through the area where the drying mechanism 44 is located, it continues to flow and then passes through the area where the wiping mechanism 43 is located, drying the wiping cloth 433. This allows the wiping cloth 433 to wipe the surface of the plastic filament for a long time without needing to be replaced, making it more convenient to use. Furthermore, after the airflow passes through the area where the wiping mechanism 43 is located, it continues to move to the area where the scraping mechanism 42 is located, and then cooperates with the lower scraper 422 to more thoroughly scrape off the cooling water on the surface of the plastic filament, reducing the pressure of subsequent wiping.

[0046] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
