Description

Technical Field

[0001] This utility model relates to the field of foamed curtain board production, and in particular to a drying device for curtain boards after water cooling. Background Technology

[0002] Currently, Venetian blind manufacturers typically set up a long water tank next to the curtain panel extruder, with a blower at the end of the tank. The newly produced, high-temperature slats are first fed into the water tank for cooling via a conveyor. As the curtain panel comes into contact with the water, it transfers heat to the water. The water flow carries away the heat from the curtain panel, thus cooling it. The cooled curtain panel is then dried by the blower. However, due to the continuous transport of the curtain panel, it is constantly in motion, and the time spent in front of the blower is short, while the area directly blown by the blower is small, resulting in poor drying effect. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a drying device for water-cooled curtain panels, which guides the air entering the inner tube to the curtain panel and forms a spiral flow around the curtain panel, so that the air and the curtain panel can fully contact each other, thereby achieving a more efficient drying effect for the curtain panel.

[0004] The technical solution of this utility model is: a drying device for water-cooled curtain panels, including a frame and a blower. A drying duct is provided on the frame. A ventilation duct is connected between the output end of the blower and one end of the drying duct. An air outlet is provided at the other end of the drying duct. An inner tube is provided on the side of the drying duct near the ventilation duct. The inner tube extends as a whole so that its right end is close to the air outlet. An airflow channel is separated between the drying duct and the inner tube. Several spiral grooves are provided on the wall of the inner tube.

[0005] Furthermore, the end of the airflow channel furthest from the ventilation duct is shaped like a ring cone.

[0006] Furthermore, spiral blades are provided on the inner wall of the inner tube along the spiral groove.

[0007] Furthermore, both ends of the air-drying duct are equipped with absorbent sponges via a locking structure.

[0008] Furthermore, the mounting structure includes at least two mounting blocks, which are fixed to both ends of the air drying duct by bolts. Two slots are provided on the mounting blocks, and bearing seats are mounted in the slots. Water-absorbing sponges are placed inside the bearing seats.

[0009] The beneficial effects of this utility model are: 1. By setting the spiral groove and the spiral blades that are set on the inner wall of the inner tube along the spiral groove, the air entering the inner tube is guided to the curtain panel and a spiral flow is formed around the curtain panel, so that the air and the curtain panel are in full contact, so as to achieve a more efficient drying effect on the curtain panel.

[0010] 2. The end of the airflow channel away from the ventilation duct is shaped like a ring cone, which concentrates part of the airflow in the airflow channel and discharges it to the air outlet, further drying the curtain panel passing through the air outlet;

[0011] 3. Absorbent sponges installed at both ends of the air-drying duct absorb water and wipe the curtain panels entering and exiting the inner duct. The sponges are detachably mounted on the mounting block via a mounting tube, making it easy to replace them manually. Attached Figure Description

Detailed Implementation

[0017] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0018] Example: Refer to Figures 1-4 A water-cooled drying device for curtain panels includes a frame 1 and a blower 2. A drying duct 3 is installed on the frame 1. A ventilation duct 4 connects the output end of the blower 2 to one end of the drying duct 3. An air outlet is located at the other end of the drying duct 3. An inner tube 5 is installed on the side of the drying duct 3 near the ventilation duct 4, extending its right end close to the air outlet. An airflow channel 6 separates the drying duct 3 and the inner tube 5. Several spiral grooves 7 are formed on the wall of the inner tube 5. The curtain panel enters the inner tube 5. The air output by blower 2 enters the drying duct 3 through ventilation duct 4, and then enters the inner tube 5 through several spiral grooves 7 to dry the curtain panel passing through the inner tube 5. The spiral grooves 7 make the air entering the inner tube 5 form a spiral flow around the curtain panel to achieve a faster and more efficient drying effect. The end of the airflow channel 6 away from the ventilation duct 4 is shaped like a ring cone, which concentrates part of the airflow in the airflow channel 6 and discharges it to the air outlet to further dry the curtain panel passing through the air outlet.

[0019] The inner wall of the inner tube 5 is provided with spiral blades 9 along the spiral groove 7. The spiral blades 9 guide the airflow that enters the inner tube 5 through the spiral groove 7 to the curtain panel, so that the wind and the curtain panel can fully contact each other to achieve a better drying effect.

[0020] Both ends of the air drying duct 3 are equipped with absorbent sponges 11 via a locking structure. The absorbent sponges 11 at both ends of the air drying duct 3 absorb water and wipe the curtain panels entering and exiting the inner tube 5. The locking structure includes at least two mounting blocks 10, which are fixed to both ends of the air drying duct 3 by bolts. Two slots are provided on the mounting blocks 10, and bearing seats 13 are locked in the slots. An installation cylinder 12 is provided in the bearing seat 13, and the absorbent sponge 11 is placed in the installation cylinder 12. The installation cylinder 12 is detachably mounted on the mounting block 10, which facilitates manual replacement of the absorbent sponge 11.

[0021] Working principle: During use, the water-cooled curtain panel is introduced into the inner tube 5 from left to right. The curtain panel is located between two absorbent sponges 11, which absorb water from the curtain panel. At the same time, the blower 2 is started. The air output by the blower 2 enters the drying duct 3 through the ventilation duct 4, and then enters the inner tube 5 through several spiral grooves 7. The curtain panel passing through the inner tube 5 is dried. The spiral grooves 7 and the spiral blades 9 corresponding to the spiral grooves 7 on the inner wall of the inner tube 5 guide the air entering the inner tube 5 to the curtain panel, forming a spiral flow around the curtain panel. This ensures that the air and the curtain panel are in full contact, achieving a more efficient drying effect. The end of the airflow channel 6 away from the ventilation duct 4 is shaped like a ring cone, which concentrates some of the airflow in the airflow channel 6 and discharges it to the air outlet, further drying the curtain panel passing through the air outlet.

[0022] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
