Description

Technical Field

[0001] The utility model relates to the technical field of polytetrafluoroethylene spraying, in particular to a self-rotating polytetrafluoroethylene spraying machine. Background Art

[0002] Polytetrafluoroethylene, commonly known as the "king of plastics", is a high molecular polymer made by polymerizing tetrafluoroethylene as a monomer. Its chemical formula is (C2F4)n. It has excellent heat and cold resistance and can be used for a long time at -180 to 260°C. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance and its friction coefficient is extremely low, so it can be used as a lubricant and has also become an ideal coating for the inner layer of easy-to-clean water pipes.

[0003] After exploration and analysis, the following shortcomings exist in actual use:

[0004] Some existing spray machines spray workpieces in a handheld manner, which may affect the uniformity of the coating. Handheld spraying is easily affected by human factors, resulting in unstable coating quality and may cause muscle fatigue and discomfort to the operator.

[0005] In summary, the present application now proposes a self-rotating polytetrafluoroethylene spraying machine to solve the above-mentioned problems. Utility Model Content

[0029] Furthermore, the rotating assembly includes a nozzle 7, a placement plate 8 and a motor 9. The rotating cylinder 4 is rotatably installed on the movable plate 3. A connecting cylinder 5 is provided at one end of the rotating cylinder 4. The rotating cylinder 4 and the connecting cylinder 5 are fixedly installed through a sleeve. The outer wall of the connecting cylinder 5 is fixedly installed with the nozzle 7. The top of the nozzle 7 passes through the connecting cylinder 5 and is fixedly installed with the outer wall of the hose 6. A placement plate 8 is fixedly installed on one side of the movable plate 3. A motor 9 is fixedly installed on the top of the placement plate 8. The output end of the motor 9 is fixedly installed with the bottom end of the bevel gear 10. The bevel gear 10 is driven to rotate by the motor 9, so that the rotation of the bevel gear 10 drives the cart 1 to rotate, thereby The rotating cylinder 4 is driven to rotate, so that the rotation of the rotating cylinder 4 drives the connecting cylinder 5 to rotate. At the same time, polytetrafluoroethylene is sprayed on the surface of the workpiece through the nozzle 7. The rotation of the connecting cylinder 5 can make the surface of the workpiece sprayed more evenly. By driving the connecting cylinder 5 to rotate, uniform coating of the workpiece surface can be achieved. The self-rotation motion ensures that the coating is evenly distributed on the entire surface, reducing the unevenness and thickness difference of the coating. At the same time, a larger surface area can be covered without changing the relative position of the workpiece, thereby improving the coating efficiency, especially for large or complex-shaped workpieces.

The free end of the hydraulic rod 14 is fixedly installed on the bottom of the movable plate 3. The movable plate 3 is pushed to slide on the column 12 by the hydraulic rod 14, so that the movement of the movable plate 3 drives the rotating cylinder 4 to move, and the rotating cylinder 4 drives the connecting cylinder 5 to move to the specified position. By adjusting the height of the connecting cylinder 5, the spraying system can adapt to workpieces of different sizes and shapes. Maintaining an appropriate distance between the nozzle 7 and the workpiece helps to maintain the uniformity of the coating. The automatic adjustment of the height of the spray tube reduces the dependence on the operator, which can reduce labor costs and reduce operating errors.

[0033] Working principle: When spraying the workpiece, move the device to the workpiece, and start the hydraulic rod 14 according to the height position of the workpiece. The hydraulic rod 14 is used to push the movable plate 3 to slide on the column 12, so that the movement of the movable plate 3 drives the rotating cylinder 4 to move, and the rotating cylinder 4 drives the connecting cylinder 5 to move to the specified position, and then start the water pump 16. The polytetrafluoroethylene inside the paint box 2 is transported to the inside of the hose 16 through the hose 2 17 through the water pump 16. At the same time, start the motor 9, and drive the bevel gear 10 to rotate through the motor 9, so that the rotation of the bevel gear 10 drives the trolley 1 to rotate, thereby driving the rotating cylinder 4 to rotate, so that the rotation of the rotating cylinder 4 drives the connecting cylinder 5 to rotate, and at the same time, polytetrafluoroethylene is sprayed on the surface of the workpiece through the nozzle 7. Through the rotation of the connecting cylinder 5, the surface of the workpiece can be sprayed more evenly.
