Description

Dryer for high-strength polyester monofilament production Technical Field

[0001] This utility model belongs to the technical field of polyester monofilament production equipment, specifically relating to a blower for producing high-strength polyester monofilament. Background Technology

[0002] In the production of polyester monofilament, surface moisture needs to be removed quickly after fiber forming to ensure the stability of subsequent processes. Traditional drying processes mainly have the following technical drawbacks:

[0003] 1. Natural air drying, commonly using the hanging natural air drying method, takes a long time. Furthermore, during the air drying process, the monofilaments undergo irreversible deformation due to gravity when suspended, which directly affects the tensile strength of the product.

[0004] 2. Mechanical brushing and some centrifugal drying methods shorten the drying time. However, the high-speed rotation causes micro-cracks on the surface of the monofilaments, and the residual moisture in the monofilaments is unevenly distributed after drying.

[0005] 3. Hot air drying: Using a hot air oven shortens the drying time, but it consumes more energy, and hot air above 70°C will cause the polyester molecular chains to deorient and the crystallinity to decrease.

[0006] Therefore, there is an urgent need for a drying equipment with short drying time and low monofilament damage rate. Summary of the Invention

[0007] The purpose of this invention is to solve the above-mentioned technical problems existing in the prior art and to provide a drying machine for the production of high-strength polyester monofilament. By adopting an upper and lower arrangement of a water collection tank and a drying component, and using a blower to supply air to the drying component through an air delivery hose, the drying component first blows off the moisture on the surface of the monofilament and then dries the monofilament. The water collection tank is used to collect the water from the monofilament. Compared with the traditional process, this significantly improves efficiency while ensuring a low damage rate to the monofilament.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A drying machine for high-strength polyester monofilament production includes a frame. One end of the frame has a water collection tank and a drying assembly. The water collection tank is fixedly connected to the frame via a connector and is located below the polyester monofilament. The drying assembly is connected to the frame via an adjusting component and is located above the polyester monofilament. The other end of the frame has a blower connected to an air supply hose. The end of the air supply hose is connected to the drying assembly, which blows air towards the water collection tank. This invention, by employing an upper and lower arrangement of the water collection tank and the drying assembly, and using a blower to supply air to the drying assembly via the air supply hose, allows the drying assembly to first blow off the moisture from the surface of the monofilament and then dry it. The water collection tank collects the water from the monofilament. Compared to traditional processes, this significantly improves efficiency while ensuring a low rate of monofilament damage.

[0010] Furthermore, the top of the water collection tank has evenly distributed water collection holes, and a water-absorbing element is installed on the top of the water collection tank. The water-absorbing element rests against the bottom of the polyester monofilament and is used to absorb the moisture from the polyester monofilament. The bottom of the water collection tank has an inclined surface, and a water outlet pipe is connected to the bottom of the water collection tank. Water dripping from the monofilament can enter the water collection tank through the water collection holes for collection. The bottom of the monofilament rests against the water-absorbing element, so that the water from the monofilament is absorbed by the water-absorbing element. Through the synergistic effect of physical adsorption and airflow drying, the drying efficiency is greatly improved. The inclined surface of the bottom of the water collection tank facilitates the drainage of water from the water collection tank through the water outlet pipe.

[0011] Furthermore, the absorbent component uses a towel and a sponge strip. The sponge strip is placed on the water collection tank, and the towel is wrapped around the outside of the sponge strip. The polyester monofilaments are pressed against the towel for transport. The water in the monofilaments is absorbed by the towel, and the water in the towel is absorbed by the sponge strip. After absorbing a certain amount of water, the water inside the sponge strip drips directly into the water collection tank due to gravity.

[0012] Furthermore, the frame includes a support frame and a mounting frame. The mounting frame is fixedly connected to the support frame, and a diagonal brace connects one end of the mounting frame to the top of the support frame. The diagonal brace increases the structural strength of the frame and improves the stability of the equipment.

[0013] Furthermore, the connectors include a column, a clamp, and a fixing plate. The column is fixedly connected within the mounting frame. One end of the fixing plate is fixedly connected to the water collection tank, and the other end is fixedly connected to the clamp. The clamp is fastened to the column. The fixed connection between the column and the mounting frame forms the main vertical support structure. The clamp locks the fixing plate to the column through a clamping method, forming a two-way constraint. The detachable nature of the clamp allows for quick adjustment of the installation height of the water collection tank, avoiding the stress concentration problem in the frame caused by traditional welding processes.

[0014] Furthermore, the adjusting component includes an adjusting rod, a base plate, an adjusting sleeve, and a second clamp. The base plate is fixedly connected to the top of the mounting frame, and the adjusting sleeve is fixedly connected to the base plate. A through hole (hole one) runs through the top of the mounting frame, and a corresponding through hole (hole two) runs through the base plate. Through holes one and two are matched with the adjusting rod, with the bottom end of the adjusting rod passing through through holes two and one in sequence. The adjusting sleeve is fitted onto the outside of the adjusting rod. By controlling the tightness of the adjusting sleeve, the adjusting rod can be raised or lowered. A crossbar is fixed to the bottom of the adjusting rod, and the end of the crossbar is fixedly connected to the second clamp, which is secured to the end of the air supply hose. The adjustment rod, through holes one and two, combined with the locking function of the adjusting sleeve, allows for adjustment of the height of the drying assembly. This design is particularly suitable for drying polyester monofilaments of different diameters, preventing excessive airflow impact that could lead to fiber breakage. The second clamp is secured to the end of the air supply hose, i.e., the connection between the air supply hose and the connector, ensuring no leakage at the air connection point.

[0015] Furthermore, the adjusting sleeve has an adjusting hole, and its outer wall has an opening that communicates with the adjusting hole. The adjusting sleeve has fixing seats on both sides of the opening, and each fixing seat has stepped holes. A locking bolt passes through two of these stepped holes, and one end of the locking bolt has a locking nut, which is tightened into one of the stepped holes on one side. By adjusting the tightness of the locking bolt and the locking nut, the adjusting sleeve can lock and release the adjusting rod. When it is necessary to control the raising and lowering of the adjusting rod, the locking nut is loosened to adjust the height of the adjusting rod. After adjustment, the locking nut is tightened again to lock the adjusting sleeve into place and fix the adjusting rod.

[0016] Furthermore, a limiting end is provided at the top of the adjusting rod. The limiting end serves to limit the raising and lowering adjustment of the adjusting rod, preventing the adjusting rod from detaching from the mounting frame.

[0017] Furthermore, the air-drying assembly includes a ventilation square tube, an adjustable side plate, and an adjustable base plate. One end of the ventilation square tube near the frame is connected to a connector, and the end of the air supply hose is connected to the connector. The other end of the ventilation square tube is closed, and an air outlet is located at the bottom of the ventilation square tube. The adjustable base plate is fixedly connected to the bottom of the ventilation square tube, and the adjustable side plate is fixedly connected to one side of the ventilation square tube. The adjustable base plate and the adjustable side plate work together to adjust the airflow direction of the air outlet. The connector facilitates the connection of the air supply hose. By controlling the angle formed between the adjustable side plate and the adjustable base plate, the air outlet angle and airflow range are controlled, ensuring uniform drying of the monofilament surface.

[0018] Furthermore, both the adjustable side plate and the adjustable base plate include a fixing part and a bending part. The fixing part has evenly distributed oblong holes, and fastening bolts are connected to the oblong holes. The fastening bolts are tightened onto the ventilation square tube. The fixing part is bent near the air outlet to form a bending part. By adjusting the bending angle of the bending part, the air outlet angle can be controlled. This facilitates the adjustment of the air outlet angle and air outlet range at any time. The oblong holes facilitate the fixing of the adjustable side plate and the adjustable base plate, and make it convenient to assemble and disassemble the adjustable side plate and the adjustable base plate.

[0020] This invention employs an upper and lower arrangement of a water collection tank and a drying assembly, with a blower supplying air to the drying assembly via a flexible air hose. The drying assembly first blows off the moisture from the surface of the monofilament, then dries the monofilament. The water collection tank collects the water from the monofilament. Compared to traditional processes, this significantly improves efficiency while ensuring a low rate of monofilament damage.

[0021] In this invention, the top of the water collection tank has evenly distributed water collection holes, and a water-absorbing element is provided on the top of the water collection tank. The water-absorbing element rests against the bottom of the polyester monofilament and is used to absorb the moisture from the polyester monofilament. The bottom of the water collection tank has an inclined surface, and a water outlet pipe is connected to the bottom of the water collection tank. Water dripping from the monofilament can enter the water collection tank through the water collection holes for collection. The bottom of the monofilament rests against the water-absorbing element, allowing the water in the monofilament to be absorbed by the water-absorbing element. Through the synergistic effect of physical adsorption and airflow drying, the drying efficiency is greatly improved. The inclined surface of the bottom of the water collection tank facilitates the drainage of water from the water collection tank through the water outlet pipe.

[0022] This utility model's air-drying assembly includes a ventilation square tube, an adjustable side plate, and an adjustable base plate. The ventilation square tube contains an air chamber, and a connector is connected to one end of the tube near the frame. The end of the air supply hose is connected to the connector, and the other end of the ventilation square tube is closed. An air outlet is located at the bottom of the ventilation square tube. The adjustable base plate is fixedly connected to the bottom of the ventilation square tube, and the adjustable side plate is fixedly connected to one side of the ventilation square tube. The adjustable base plate and the adjustable side plate work together to adjust the airflow direction of the air outlet. The connector facilitates the connection of the air supply hose. By controlling the angle formed between the adjustable side plate and the adjustable base plate, the air outlet angle and airflow range are controlled, ensuring uniform drying of the monofilament surface.
