[0024] 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.

[0025] Please see Figures 1-6 This utility model provides a technical solution: a mounting frame for a roller shutter type air filter, including a mounting frame 1, a roller 2 mounted on the bottom end of the mounting frame 1, a take-up roller 3 mounted at the middle position of the bottom end inside the mounting frame 1, a controller 4 mounted on one side of the mounting frame 1, a cavity 8 mounted on the rear side of the bottom end inside the mounting frame 1, a moving mechanism provided inside the cavity 8, filter cloth fixing frames 5 mounted on both the front and rear ends of the mounting frame 1, a mounting cavity 6 mounted on the top end of the mounting frame 1, and a traction mechanism provided on the inner side of the mounting frame 1.

[0026] like Figures 1-6As shown, the traction mechanism includes a traction frame 7, an electric telescopic rod 701, a clamping plate 702, and a moving assembly. The traction frame 7 is installed inside the mounting frame 1. Electric telescopic rods 701 are installed at both the front and rear ends of the traction frame 7. The clamping plate 702 is installed inside the traction frame 7. The output end of the electric telescopic rod 701 is connected to one end of the clamping plate 702. Moving assemblies are provided on both sides of the traction frame 7. The moving assemblies include a first servo motor 703, a first bevel gear 704, and a second bevel gear 705. The system includes a threaded rod 706, a threaded sleeve 707, and a limiting structure. A first servo motor 703 is mounted on the upper side of one side of the mounting bracket 1. A first bevel gear 704 is mounted on the upper side of the inner side of the mounting bracket 1. The output end of the first servo motor 703 is connected to one end of the first bevel gear 704. A second bevel gear 705 meshes with the lower part of the first bevel gear 704. A threaded rod 706 is mounted on the bottom end of the second bevel gear 705. A threaded sleeve 707 is provided on the outer wall of the threaded rod 706. One end of the filter cloth is connected to one end of the traction frame 7. In use, the filter cloth is placed inside the mounting cavity 6 and one end of it is placed inside the traction frame 7. At this time, the electric telescopic rod 701 is activated to move the clamping plate 702. The two clamping plates 702 are used to clamp the filter cloth. Then, the first servo motor 703 is activated to drive the first bevel gear 704 to rotate. Since the first bevel gear 704 and the second bevel gear 705 are meshed with each other, the second bevel gear 705 is used to drive the threaded rod 706 to rotate. Then, under the limit of the limit rod 708 and the limit sleeve 709, the threaded sleeve 707 is used to drive the traction frame 7 to move, thereby driving the filter cloth to be pulled. The filter cloth is moved to the bottom of the mounting frame 1. Then, the operator winds it around the take-up roller 3 to clamp and fix the filter cloth. Then, the filter cloth is automatically pulled, making it more convenient and faster to replace the filter cloth, reducing the labor intensity of the workers, and thus greatly improving the practicality of the frame in use.

[0027] like Figures 1-6 As shown, the limiting structure includes a limiting rod 708 and a limiting sleeve 709. The limiting rod 708 is installed on the other side inside the mounting bracket 1. The limiting sleeve 709 is provided on the outer wall of the limiting rod 708. One end of the limiting sleeve 709 is connected to the other end of the traction frame 7. The cross-section of the limiting rod 708 is smaller than the cross-section of the limiting sleeve 709. The limiting rod 708 and the limiting sleeve 709 form a sliding structure. In use, the mutual cooperation between the limiting rod 708 and the limiting sleeve 709 can limit the movement of the traction frame 7, making the traction frame 7 more stable when moving.

[0028] like Figures 1-6As shown, the moving mechanism includes a second servo motor 801, a screw 802, a screw sleeve 803, a movable cavity 804, a frame 805, a limiting groove 806, and a limiting block 807. The second servo motor 801 is mounted on the top of the cavity 8. The screw 802 is installed inside the cavity 8. The output end of the second servo motor 801 is connected to one end of the screw 802. A screw sleeve 803 is provided on the outer wall of the screw 802. The movable cavity 804 is fixedly installed on the outer wall of the screw sleeve 803. The bottom end of the movable cavity 804 extends to the bottom of the mounting frame 1. The frame 805 is installed at the bottom end of the movable cavity 804. The bottom end of the frame 805 is connected to the top of the roller 2. A limiting groove 806 is opened inside the cavity 8. A limiting block 807 is provided inside the limiting groove 806. One end is connected to the outside of the movable cavity 804. In use, the second servo motor 801 is started to drive the screw 802 to rotate, which in turn drives the screw sleeve 803 to move. Under the limit of the limit groove 806 and the limit block 807, the screw sleeve 803 drives the movable cavity 804 to move, which in turn drives the frame 805 to move downward, which in turn drives the roller 2 to move downward. At this time, the mounting frame is pushed to move it to the appropriate position. Then, the second servo motor 801 is started to reverse, which drives the roller 2 to retract, so that the bottom end of the mounting frame 1 contacts the ground. This makes the mounting frame more convenient and faster to transport or move, eliminating the need for manual handling. It also makes the frame more stable during use, thereby greatly improving the practicality of the frame.

[0029] like Figures 1-6 As shown, two limit blocks 807 are provided on the outside of the movable cavity 804. The two limit blocks 807 are symmetrically distributed about the central axis of the movable cavity 804. In use, the mutual cooperation between the limit groove 806 and the limit block 807 can limit the movement of the movable cavity 804, making the movable cavity 804 more stable when moving.

[0030] The operation and working principle of this device are as follows: First, the operator starts the second servo motor 801 to rotate the screw 802, which in turn moves the screw sleeve 803. Under the limitation of the limiting groove 806 and the limiting block 807, the screw sleeve 803 moves the movable cavity 804, which in turn moves the frame 805 downwards, causing the roller 2 to move downwards. At this point, the mounting frame is pushed to the appropriate position. Then, the second servo motor 801 is started in reverse, causing the roller 2 to retract, so that the bottom of the mounting frame 1 contacts the ground. The filter cloth is then placed inside the mounting cavity 6, and one end is placed into the traction frame 7. Inside the filter cloth, the electric telescopic rod 701 is activated to move the clamping plate 702. The two clamping plates 702 are used to clamp the filter cloth. Then, the first servo motor 703 is activated to rotate the first bevel gear 704. Since the first bevel gear 704 and the second bevel gear 705 are meshed with each other, the second bevel gear 705 is used to rotate the threaded rod 706. Then, under the limit of the limiting rod 708 and the limiting sleeve 709, the threaded sleeve 707 is used to move the traction frame 7, thereby pulling the filter cloth to move it to the bottom of the mounting frame 1. Then, the operator winds it onto the take-up roller 3.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
