Description

Technical Field

[0001] This invention relates to the technical field of textile equipment, specifically to a cooling device and production process for polypropylene filament production. Background Technology

[0002] A Chinese patent document with publication number CN113758117A discloses a rapid cooling device and method for polypropylene yarn processing. The device includes a cooling control plate, two active cooling wheels, a drive mechanism, two wheel cooling mechanisms, two driven cooling wheels, a drive wheel, a cooling box, a coolant mechanism, and a blower mechanism. The two active cooling wheels are rotatably mounted on one side of the cooling control plate. The drive mechanism is mounted on the cooling control plate and connected to the two active cooling wheels. The drive mechanism includes two driven sprockets, a chain, a stepper motor, and an active sprocket. A round rod is fixedly mounted on one side of each of the two active cooling wheels. Both round rods are rotatably mounted on the cooling control plate, and a driven sprocket is fixedly mounted at one end of each round rod. The two driven sprockets are connected to the same chain. A cooling control plate is fixedly mounted on one side... A second stepper motor has a drive sprocket fixedly connected to its output shaft. The drive sprocket is connected to a chain drive. A wheel cooling mechanism is installed on the corresponding drive cooling wheel. Two driven cooling wheels are rotatably mounted on a cooling control plate. A cooling box is fixedly mounted on one side of the cooling control plate. The top of the cooling box is open. A drive wheel is rotatably mounted inside the cooling box. A coolant mechanism is installed inside the cooling box. A blower mechanism is installed on the cooling control plate. Two circulating pumps are fixedly mounted on one side of the cooling control plate. Connecting pipes are fixedly mounted on the outlets of the two circulating pumps.

A ring gear 11 is integrally formed on the inner side of the cooling wheel 3. A reduction motor 9 is fixedly mounted on the mounting plate 6. A transmission gear 10 is fixedly mounted on the output shaft of the reduction motor 9. The transmission gear 10 is meshed with the ring gear 11.

When the rubber sealing ring 15 is actually installed, the alignment protrusion 22 is embedded into the alignment groove 21. The secondary air groove 17 is misaligned with the alignment protrusion 22. Through the arrangement of the alignment protrusion 22 and the alignment groove 21, the primary air groove 16 and the secondary air groove 17 are always aligned.

[0020] An air chamber 20 is provided at the end of the main air passage 18. The primary air groove 16 is connected to the air chamber 20. The primary air passage 23 is arranged in a circle around the cooling wheel 3.

When the cooling air passage 39 is aligned with the fiber filament 40 in the direction of the polypropylene filament forming equipment 2, the primary air passage 23 connected to the cooling air passage 39 is located in the middle of the primary air groove 16.

[0021] When the cooling air duct 39 moves to its lowest position, the water in the cooling water tank 5 completely submerges the corresponding cooling air duct 39.

It ensures that the lower side of the guide wheel 4 is in contact with the water in the cooling water tank 5, so that the cooling air passage 39 is wetted by the water in the cooling water tank 5, thereby increasing the humidity of the airflow blown out of the cooling air passage 39, increasing the specific heat capacity of the airflow, so that the airflow can carry away more heat, thereby improving the cooling and shaping efficiency of the fiber filament 40.

[0022] In Example 2, based on Example 1, a water storage mechanism 27 is provided in the cooling air duct 39. The water storage mechanism 27 includes a water storage ring 28 and a connecting rod 29.

Multiple water storage micropores 38 are evenly arranged on the water storage ring 28, and the straight line of the water storage ring 28 is perpendicular to the axis of the cooling air duct 39. By setting the water storage mechanism 27, which is composed of water storage rings 28 and connecting rods 29, in the cooling air duct 39, and opening water storage micropores 38 on the water storage ring 28, and ensuring that the straight line of the water storage ring 28 is perpendicular to the axis of the cooling air duct 39, the water accumulated in the water storage micropores 38 can be slowly released under negative pressure by utilizing Bernoulli's principle, thereby ensuring the humidification effect on the airflow.

[0024] A crossbar 33 is integrally formed in the connecting ring 31, and a pull rod 34 is welded on the crossbar 33. When the elastic piece 32 is engaged in the engagement groove 35, the end of the pull rod 34 protrudes outside the port of the cooling air passage 39. An anti-slip protrusion 36 is integrally formed on the side wall of the pull rod 34, which makes it convenient for the staff to remove the water storage mechanism 27 through the clamping mechanism.

[0025] Example 3, based on Example 2, provides a polypropylene filament production process. This process utilizes the aforementioned cooling equipment for polypropylene filament production and processing. The process involves forming the filament 40 using a polypropylene filament forming device 2, followed by air supply via an air supply device. The airflow sequentially passes through the main air duct 18, air chamber 20, primary air duct 23, secondary air duct 24, tertiary air duct 25, and quaternary air duct 26, and finally exits through the cooling air duct 39. This achieves the purpose of cooling and shaping the filament 40. The lower part of the cooling wheel 3 is immersed in the cooling water tank 5 for cooling, and the cooling air duct 39 is moistened, increasing the humidity of the airflow and thus increasing its specific heat capacity. This allows the airflow to carry away more heat, thereby improving the cooling and shaping effect on the filament 40.
