DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0019] The technical solution of the present utility model is further described below with reference to the accompanying drawings. Figure 1-2The invention shows a mechanism for winding an air filter clamp band, comprising a disc 1, a clamping mechanism 2, a turntable 3, a cylinder 4, and a rack 5. The bottom of the disc 1 is fixed horizontally to the turntable 3, which is fixed horizontally to a bracket 8. Tooth grooves are provided circumferentially of the turntable 3. The cylinder 4 is fixed horizontally to the bracket 8. The telescopic end of the cylinder 4 is horizontally connected to a rack 5, which is arranged in coordination with the tooth grooves. A gap is left between the clamping mechanism and the disc 1 to allow the clamp band 6 to pass through. The bottom of the clamping mechanism is fixed horizontally to the bracket 8. The disc 1 is designed according to the diameter of the clamp band 6 to ensure dimensional consistency. The use of a rack and pinion transmission ensures rapid prototyping, improves production efficiency, and provides stable power transmission. The use of pneumatic power to control the rack and pinion transmission can save electricity and directly use network air pressure, which is safe, convenient, and energy-saving.

[0020] As an embodiment of the present invention, Figure 2 The clamping mechanism 2 includes a roller 7, a first articulated arm 9, a second articulated arm 10, a fixing seat 11 and a roller frame 12. The non-articulated ends of the first articulated arm 9 and the second articulated arm 10 are fixed to the bracket 8 with the fixing seat 11 and are arranged perpendicularly to each other. A roller frame 12 is fixed on the first articulated arm 9. The roller 7 is arranged in the roller frame 12. The roller 7 is arranged in the circumference of the disc 1, and a gap is left between them for the clamping band 6 to pass through. The above-mentioned roller extrusion adopts the lever principle to control the clamping force. The use of rollers to extrude the clamping band can effectively protect the surface quality of the clamping band from scratches, and at the same time control the arc rebound formed after the clamping band is wrapped, ensuring that the size of the clamping band after being rolled meets the design requirements of the drawing.

[0021] In order to further adjust and control the pressing force, Figure 2 Preferably, a slide 13 can be provided between the fixing seat 11 and the bracket 8, and the bottom of the slide 13 is fixed to the bracket 8. A slide groove 14 is provided on the top of the slide 13, and the bottom of the fixing seat 11 is engaged with the slide groove 14. When the roller is attached to the clamping belt, the two articulated arms can slide on the slide groove 14 while being articulated, thereby increasing the roller buffer stroke and further controlling its rebound.

[0022] As another embodiment of the present invention, the clamping mechanism can be configured as an elastic sheet, which is vertically positioned opposite the disc 1, leaving a gap therebetween for the clamping band 6 to pass through, and the bottom of the elastic sheet is fixed to the bracket 8. The force of elastic deformation recovery is used to control the clamping force.

[0023] In order to further reduce the wear caused by the clamping band 6 when wrapping the circumference of the disc 1, a rubber sleeve can be attached to the circumference of the disc 1.

[0024] In order to increase the hardness capable of withstanding the clamping band, the material of the disc 1 is designed to be a cold-rolled steel plate.

[0025] The working principle of this utility model is as follows: Figure 1 , place one end of the hoop belt 6 between the roller 7 and the circumference of the disc 1, start the cylinder 4, and when its telescopic end extends or retracts, it drives the rack 5 on it to move synchronously. The rack 5 engages with the teeth on the circumference of the turntable 3, thereby driving the turntable 3 to rotate, and the roller 7 presses the hoop belt 6 to be rolled into an arc shape.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
