[0021] Furthermore, the power device includes a low-speed motor 8, a driving gear 9 and a transmission tooth groove 10. An extension seat plate is installed on the front side of the side frame 2. The low-speed motor 8 is installed on the right side of the extension seat plate. The driving gear 9 is installed on the output end of the low-speed motor 8. The transmission tooth groove 10 is opened on the outer surface of the support cylinder frame 3. The driving gear 9 is engaged with the transmission tooth groove 10. When the low-speed motor 8 rotates, the support cylinder frame 3 is driven to rotate through the cooperation of the driving gear 9 and the transmission tooth groove 10, and the airbag 7 is driven to rotate through the support cylinder frame 3 to perform grinding work.

[0022] Furthermore, the sealing device includes a sealing cover 11, a connecting notch 12, an expansion sealing strip 13 and a boosting hole 51. The sealing cover 11 is installed on the outer wall of the support tube frame 3 and is located at the right end. The connecting notch 12 is opened on the outer wall of the sealing cover 11. The expansion sealing strip 13 is installed on the outer surface of the sealing cover 11 and is located outside the connecting notch 12. The boosting pipe 5 and the dust exhaust pipe 6 both pass through the sealing cover 11. The boosting hole 51 is opened on the surface of the boosting pipe 5 and is located on the inner side of the sealing cover 11. A wind shield ring is installed inside the boosting pipe 5 and on the right side of the boosting hole 51. The wind shield ring reduces the flow diameter of the boosting pipe 5, so that the air pressure at the boosting hole 51 increases, so that the high-pressure gas enters the sealing cover 11 through the boosting hole 51 for boosting, and the pressurized gas presses the expansion sealing strip 13 to expand and seal the bottle mouth.

[0023] Furthermore, the supporting device includes a positioning telescopic bracket 14, a bottle body support bracket 15 and an adjusting support seat 16. The positioning telescopic bracket 14 is installed on the top of the base plate 1, the bottle body support bracket 15 is installed on the top of the positioning telescopic bracket 14, the adjusting support seat 16 is installed on the top of the base plate 1 and is located below the bottle body support bracket 15, and the top of the adjusting support seat 16 is installed on the bottom of the bottle body support bracket 15. The bottle body is supported by the bottle body support bracket 15. When grinding, the bottle body is pushed to the left along the bottle body support bracket 15 to insert the airbag 7 into the inside of the bottle body, and then the bottle body is supported by hand for grinding.

[0024] Furthermore, the regulating support seat 16 is composed of a positioning sleeve at the bottom and a telescopic column at the top. A regulating nut is installed on the top of the positioning sleeve through a bearing. The regulating nut is threadedly connected to the telescopic column. By rotating the regulating nut, the telescopic column is controlled to move up and down through the limitation of the thread, thereby regulating the support height of the bottle body support frame 15. The support height is adjusted according to the diameter of the bottle body to be polished as needed, so that the axis of the bottle body and the support tube frame 3 are in the same straight line position.

[0025] Furthermore, the bottle support frame 15 is V-shaped as a whole. The V-shaped design facilitates the placement of the bottle, and the bottle can automatically align to the middle after placement to prevent misalignment from affecting the polishing quality.

[0026] When in use, connect the pressure control pipe 4 with the booster, connect the air outlet pipe of the filter fan with the left end of the booster pipe 5, install the exhaust pipe of the filter fan with the left end of the dust exhaust pipe 6, place the pulp molded bottle on the bottle support frame 15, push the bottle to move to the left, insert the airbag 7 into the bottle, and continue to push the bottle to the left until the sealing cover 11 moves into the bottle mouth. Then, the pressurized gas is injected into the airbag 7 along the pressure control pipe 4 through the booster to make the airbag 7 expand and contact the inner wall of the bottle. At the same time, the filter fan is controlled to blow air into the booster pipe 5. When the high-pressure gas flows to the right along the booster pipe 5 to the position of the wind shield ring, it is blocked, causing the air pressure at the position of the booster hole 51 to increase, and the high-pressure gas enters the sealing cover 11. The high-pressure gas inside the sealing cover 11 presses the expansion sealing strip 13 to expand and fit the inner wall of the bottle mouth of the bottle, thereby sealing the bottle. At the same time, the low-speed motor 8 is started. After the air bag 7 is polished, the air in the air bag 7 is blown away by the pressure pipe 5, and the dust is discharged from the dust pipe 6 along the air flow through the dust pipe 6 to complete the polishing process.

[0027] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
