Description

Technical Field

[0001] This utility model relates to the field of filter screen winding and cooling technology, specifically a filter screen winding device with cooling function. Background Technology

[0002] The filter screen winding device is used to wind and rewind the produced filter screen material into a roll shape. It winds continuous filter screen material (such as metal wire mesh, plastic filter screen, non-woven filter screen, etc.) evenly onto the core or roller according to the set tension, speed and roll diameter to form a compact and neat roll. A filter screen winding device with cooling function is used because the operation of the equipment and friction of materials during the winding process can generate heat, which may cause the filter screen to deform and its performance to decline. The device is equipped with a cooling system that can remove the heat in time, keep the filter screen at a suitable temperature, and ensure its dimensional stability and filtration performance. Existing cooling systems for winding devices mostly employ side-mounted air-cooling mechanisms, using centrifugal fans to generate cooling air that blows directly onto the winding roller. However, this cooling method has significant drawbacks. From a fluid dynamics perspective, the winding roller, being a cylindrical structure, obstructs the airflow path of the cooling air, causing airflow separation. When the cooling air contacts the surface of the winding roller, a large-area vortex zone is formed on the leeward side of the roller. Most of the cooling air cannot fully contact the filter screen due to the obstruction of the winding roller, failing to remove heat in time and thus failing to meet the requirements for efficient heat dissipation. Therefore, to address these issues, a filter screen winding device with cooling function is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a filter screen winding device with cooling function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A filter screen winding device with cooling function includes a winding machine body. A support column is fixedly connected to one side of the winding machine body. A support mechanism is fixed to the top of the support column by bolts. An air supply mechanism is installed above the support mechanism. The air supply mechanism includes two air ducts. A hinged seat is fixedly connected to one side of each air duct. An air supply pipe mechanism is hinged between the two hinged seats. A symmetrical support wheel frame is fixedly connected to the bottom of each air duct. A rotating shaft is rotatably connected to the bottom of each support wheel frame. A grooved support wheel is fixedly connected to the front end of the rotating shaft. A push block is fixedly connected to one side of the rotating shaft. The air supply pipe mechanism includes two hinged rods. The hinged rods are hinged to the front end of the hinged seats via a connecting shaft. A movable air duct is hinged between the two hinged rods. An air outlet cavity is opened on the lower surface of the movable air duct. Transmission blocks are fixedly connected to both sides of the lower surface of the movable air duct. The push block and the transmission block are rotatably engaged.

[0005] As a further optimization of this utility model, the lower surface of the transmission block has an arc-shaped structure, the number of push blocks is the same as the number of transmission blocks, and the push blocks are located below the transmission blocks.

[0006] As a further optimization of this utility model, the center of the grooved support wheel and the center of the rotation shaft are located on the same central axis, the grooved support wheel is located inside the support wheel frame, there is a gap between the grooved support wheel and the air duct, and the outer wall of the grooved support wheel is provided with a ventilation groove.

[0007] As a further optimization of this utility model, the bottom end of the air duct is fixedly connected to a lower air supply pipe, which is located between two support wheel frames, and a connecting hose is fixedly connected to the interior of the movable air duct at the middle of one side of the air duct.

[0008] As a further optimization of this utility model, the support mechanism includes a support base, which is fixedly mounted on the top of a support column by bolts. A bearing seat is fixedly connected to the top of the support base, and a support rail is fixedly connected to the top of the bearing seat. A slide block is slidably connected to the front end face of the support rail, and a connecting frame is fixedly connected to the front end of the slide block. The connecting frame is fixedly connected to the air duct.

[0009] As a further optimization of this utility model, a winding roller is rotatably connected between the two bearing seats, and an adjusting shaft is rotatably connected to one end of one of the bearing seats. The adjusting shaft extends into the interior of the bearing seat and is engaged with the winding roller. A transmission gear is fixedly connected to one end of the adjusting shaft.

[0010] As a further optimization of this utility model, an air inlet pipe is fixedly connected through the middle of the other side of the air duct, and the air inlet pipe extends to the outside of the connecting frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a support mechanism, an air supply mechanism, and an air supply duct mechanism are incorporated. The air supply mechanism utilizes a grooved support wheel with ventilation grooves on its outer wall to reduce airflow obstruction. Combined with a diversion design, this allows cooling air to cover the filter screen surface and the winding area. A rotating shaft drives a push block and a transmission block, causing the movable air duct to vibrate up and down, altering the airflow path and speed. This design breaks away from the traditional single air supply mode. Based on the principle of fluid disturbance, it effectively enhances the scouring effect of airflow on the filter screen surface, improving the convective heat transfer coefficient. In the support mechanism, as the winding roller increases the filter screen thickness, the grooved support wheel drives the air duct upwards, ensuring that the cooling air automatically adjusts its height according to the filter screen thickness. This device effectively solves the problem of existing winding devices where cooling air cannot effectively contact the filter screen, promptly removing heat and maintaining a suitable filter screen temperature.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-7 This utility model provides a technical solution: A filter screen winding device with cooling function includes a winding machine body 1. A support column 2 is fixedly connected to one side of the winding machine body 1. A support mechanism 3 is fixed to the top of the support column 2 by bolts. An air supply mechanism 4 is installed above the support mechanism 3. The air supply mechanism 4 includes two air ducts 41. A hinge seat 42 is fixedly connected to one side of the air duct 41. An air supply pipe mechanism 43 is hinged between the two hinge seats 42. A left-right symmetrical support wheel frame 44 is fixedly connected to the bottom of the air duct 41. The bottom of the support wheel frame 44 is rotatably connected. A rotating shaft 45 is connected to the front end of the rotating shaft 45, and a grooved support wheel 46 is fixedly connected to the front end of the rotating shaft 45. A push block 48 is fixedly connected to one side of the rotating shaft 45. The air supply duct mechanism 43 includes two hinge rods 431. The hinge rods 431 are hinged to the front end of the hinge seat 42 through a connecting shaft. A movable air duct 432 is hinged between the two hinge rods 431. An air outlet cavity 433 is opened on the lower surface of the movable air duct 432. A transmission block 434 is fixedly connected to both sides of the lower surface of the movable air duct 432. The push block 48 is rotatably engaged with the transmission block 434.

[0017] As a further implementation of this solution, the lower surface of the transmission block 434 has an arc-shaped structure. The number of push blocks 48 is the same as the number of transmission blocks 434. The push blocks 48 are located below the transmission block 434. When the rotating shaft 45 drives the push blocks 48 to rotate, the top of the push blocks 48 slides along the arc-shaped surface, pushing the transmission block 434 to move up and down. Because the hinge rod 431 is hinged to the hinge seat 42, the movable air duct 432 can vibrate up and down with the transmission block 434, so that the cooling air outlet path and speed change periodically, enhancing the cooling uniformity of the filter screen. As a further implementation of this solution, the center of the grooved support wheel 46 and the center of the rotating shaft 45 are located on the same central axis. The grooved support wheel 46 is located inside the support wheel frame 44. There is a gap between the grooved support wheel 46 and the air duct 41. The outer wall of the grooved support wheel 46 is provided with a ventilation groove 47, which forms an airflow channel to reduce the obstruction of the wheel body to the wind. As a further implementation of this solution, a lower air supply pipe 5 is fixedly connected to the bottom of the air duct 41. The lower air supply pipe 5 is located between the two support wheel frames 44. A connecting hose 49 is fixedly connected to the middle of one side of the air duct 41 and the interior of the movable air duct 432. This diversion design allows the cooling air to act on the surface of the filter screen and the winding area at the same time, expanding the cooling coverage and improving the heat dissipation efficiency. As a further implementation of this solution, the support mechanism 3 includes a support base 31, which is fixedly mounted on the top of the support column 2 by bolts. A bearing seat 32 is fixedly connected to the top of the support base 31, and a support rail 33 is fixedly connected to the top of the bearing seat 32. A slide block 34 is slidably connected to the front end of the support rail 33, and a connecting frame 35 is fixedly connected to the front end of the slide block 34. The connecting frame 35 is fixedly connected to the air duct 41. A winding roller 6 is rotatably connected between the two bearing seats 32. An adjusting shaft 36 is rotatably connected to one end of one of the bearing seats 32. The adjusting shaft 36 extends into the interior of the bearing seat 32 and engages with the winding roller 6. A transmission gear 7 is fixedly connected to one end of the adjusting shaft 36. When the winding roller 6 winds, the increased thickness of the filter screen pushes the grooved support wheel 46 upward. The air duct 41 drives the slide block 34 to move along the path of the support rail 33, ensuring that the cooling air can be automatically adjusted to different heights according to the change in the thickness of the filter screen. As a further implementation of this solution, an air inlet pipe 8 is fixedly connected through the middle of the other side of the air duct 41. The air inlet pipe 8 extends to the outside of the connecting frame 35, and the air inlet pipe 8 and the connecting frame 35 are rotatably connected by a bearing.

[0018] Workflow: Support column 2 provides support for support mechanism 3. Winding machine body 1 starts. The built-in motor of winding machine body 1 meshes with transmission gear 7 through gear set to provide power to transmission gear 7. Transmission gear 7 drives winding roller 6 to rotate synchronously through adjusting shaft 36. The rotation of winding roller 6 pulls the filter screen to start winding operation. At the same time, the air supply pipe of the external fan is connected to the air inlet pipe 8, and the cooling air enters the air duct 41 through the air inlet pipe 8 for distribution. Part of the airflow in the air duct 41 is transported downward through the lower air supply pipe 5 and along the surface of the filter screen to both sides. In order to further reduce the influence of grooved support wheel 46 on airflow, an annular ventilation groove 47 is opened on the outer wall of grooved support wheel 46. Airflow is sent out through the ventilation groove 47 of grooved support wheel 46 and acts on the wound filter screen to achieve preliminary cooling. Another part of the airflow enters the movable air duct 432 through connecting hose 49 and exits from the air outlet 433, further improving the cooling range. Because the grooved support wheel 46 is in contact with the surface of the filter screen, as the thickness of the filter screen on the surface of the winding roller 6 increases, the grooved support wheel 46 will drive the air duct 41 to move upward through the support wheel frame 44, and the slide 34 will move upward synchronously along the support rail 33. This ensures the accuracy of the movement of the support mechanism 3 and ensures that the cooling air can be automatically adjusted to different heights according to the thickness of the filter screen. During winding, the grooved support wheel 46 contacts the rotating filter screen and rotates, so that the grooved support wheel 46 can drive the rotating shaft 45 to rotate synchronously. The rotating shaft 45 drives the push block 48 to rotate. Since the push block 48 slides into contact with the transmission block 434 every time it rotates, it pushes the movable air duct 432 upward. Because the hinge rod 431 is hinged to the hinge seat 42, it provides space for the movable air duct 432 to vibrate up and down, thereby changing the cooling air outlet path and speed and improving the cooling effect.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
