Description

Technical Field

[0001] The utility model belongs to the technical field of quick-change non-woven drum sanding wheels, and particularly relates to a quick-change non-woven drum sanding wheel. Background Art

[0002] An impeller, usually also known as a flap wheel or a thousand-sheet wheel, is a coated abrasive tool mainly used for grinding and polishing. It consists of many abrasive cloth or sandpaper sheets bonded to a mesh cover made of plastic or fiber, arranged in a fan-shaped or radial pattern, resembling a wheel. These sheets can range from dozens to thousands, hence the names "flap wheel" or "thousand-sheet wheel". The main difference between a flap wheel and a thousand-sheet wheel lies in the number of sheets, but their functions are similar. They both achieve grinding, rust removal, paint removal, deburring, and weld grinding on metal or non-metal surfaces by high-speed rotation. They are suitable for different working requirements, such as shipbuilding, automotive manufacturing, aerospace, mechanical equipment, instrument manufacturing, bridge and construction projects, and furniture manufacturing industries. In the process of using the existing quick-change non-woven drum sanding wheel, when the impeller needs to be replaced after use, the impeller often needs to be installed by adjusting the tightness between the threads, which will result in a waste of the device's operating efficiency.

[0003] For example, the utility model with the publication number CN212601313U discloses a quick-installation special drum grinding flap wheel for a wire drawing machine. In the technical solution of this patent, it includes a connecting piece, an adhesive core shaft, and vertical sheets arranged circumferentially and evenly on the outside of the adhesive core shaft. The connecting piece is a quick-change threaded hole core shaft. One end of the quick-change threaded hole core shaft extends out of the impeller, and the other end is not higher than the end face of the impeller. The adhesive core shaft is located between the connecting piece and the inner end of the sheet. The sheet is a grid-shaped sheet structure woven from polyester nylon fibers adhered with abrasive particles or a composite sheet containing this grid-shaped sheet structure. In the process of using this device, when the impeller needs to be replaced after use, the impeller often needs to be installed by adjusting the tightness between the threads, which will result in a waste of the device's operating efficiency. Therefore, a quick-change non-woven drum sanding wheel is proposed. Summary of the Utility Model

[0004] In view of this, aiming at the deficiencies of the prior art, the utility model provides a quick-change non-woven drum sanding wheel, which can not only grind materials, but also replace the impeller relatively quickly, thereby improving the overall operation efficiency of the device.

[0005] To solve the above technical problems, the technical solution adopted by the present utility model is as follows: A quick-change non-woven fabric drum sanding wheel, including a connecting piece, with a plurality of sand blades arranged on the periphery of the connecting piece, and a quick-connection structure arranged in the middle of the connecting piece. The quick-connection structure includes a square hole one arranged at the connection center, a square shaft arranged in the middle of the square hole one, a threaded column arranged on the right side of the square shaft, a gasket close to the sanding wheel arranged on the threaded column, a nut sleeved on the threaded column arranged at the right end of the gasket, a connecting shaft arranged on the left side of the square shaft, the connecting shaft is square, a square hole two is arranged in the middle of the connecting shaft, round holes are respectively arranged on the front and rear sides of the square hole two, and a clamping mechanism is arranged at the top of the connecting shaft.

[0006] As a further improvement of the present utility model, the clamping mechanism includes a fixed shaft arranged at the top of the connecting shaft, a baffle arranged at the top of the fixed shaft, a spring arranged on the fixed shaft, a sliding sleeve slidably arranged on the fixed shaft, a connecting rod arranged on the left side of the sliding sleeve, U-shaped frames are respectively arranged at the front and rear ends of the connecting rod, rotating shafts are respectively hinged inside the two U-shaped frames, U-shaped plates are arranged at the ends of the two rotating shafts away from the U-shaped frames, and a guide rod passing through the round hole is hinged inside the U-shaped plate.

[0007] As a further improvement of the present utility model, a sliding rod is slidably arranged inside the square hole two, guide grooves connected to the guide rods are respectively arranged on the front and rear sides of the sliding rod, connecting holes are arranged inside the guide grooves, a cylinder is arranged on the left side of the sliding rod, a support plate is arranged on the left side of the cylinder, a rotating motor connected to the cylinder is arranged on the left side of the support plate, the rotating motor and the cylinder are connected through a coupling, and a switch is arranged on the front side of the support plate, and the switch is connected to the rotating motor.

[0008] As a further improvement of the present utility model, a bottom plate is arranged at the bottom of the support plate, support legs are respectively arranged at the four corners of the bottom of the bottom plate, and anti-slip pads are respectively arranged at the bottoms of the four support legs.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] First, when the sanding wheel needs to be replaced, loosen the nut, remove the gasket after the nut is loosened, and then remove the sanding wheel from the square shaft. The setting of the square hole one facilitates the collection and installation of the sanding wheel.

[0011] Second, when the connecting shaft needs to be quickly taken, first press the connecting rod. The downward pressure of the connecting rod causes the sliding sleeve to slide on the fixed shaft. At this time, the sliding will be blocked by the spring, so that the sliding sleeve is moved to contact the baffle. The movement of the connecting rod drives the rotating shaft connected to the U-shaped frame to rotate, thereby driving the guide rod connected to the U-shaped plate to slide inside the round hole, so as to fix the sliding rod inside the square hole two.

[0012] Thirdly, guiding grooves are respectively arranged at the front and rear ends of the sliding rod, and a plurality of connecting holes are arranged inside the guiding grooves. The arrangement of the connecting holes can facilitate the step-by-step adjustment of the connecting shaft.

[0013] Fourthly, support legs are arranged at the bottom of the bottom plate, and the design of the support legs makes the device more stable. Description of the Drawings
