DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0027] Embodiment 1

[0028] Referring to Figure 1 A surface treatment equipment, comprising: bottom column 1, outer ring 2, station groove 3, rotary table 4, clamping mechanism 5, plasma surface treatment machine 6 and conveyor 7. The outer wall top of bottom column 1 is fixedly provided with outer ring 2, and the top of bottom column 1 is rotationally provided with rotary table 4, and the outer wall of rotary table 4 is uniformly provided with a plurality of station grooves 3. Plasma surface treatment machine 6 is located at one side of bottom column 1 and is used for surface treatment of plastic bottles. Clamping mechanism 5 is located at one side of bottom column 1 and is used for clamping and rotating plastic bottles.

[0029] Referring to Figures 2-4The clamping mechanism 5 comprises a bracket 8, an upper clamping plate 18 and a lower clamping plate 15. The bracket 8 is located on one side of the bottom column 1, and a limiting rod 11 is fixedly arranged in the bracket 8. Two mounting plates 13 are slidingly sleeved on the outer wall of the limiting rod 11. An arc-shaped inclined hole 10 is formed in the top and bottom of the outer wall of a rotating cylinder 9 rotatably arranged in the bracket 8. One end of each of the two mounting plates 13 is fixedly provided with an extension rod 21, and the two extension rods 21 are respectively matched with the two arc-shaped inclined holes 10, so that the mounting plate 13 can slide along the limiting rod 11 when the rotating cylinder 9 rotates.

[0030] With reference to Figure 2 A first servo motor 12 is fixedly arranged in the bracket 8, and the output shaft of the first servo motor 12 is fixedly connected with the bottom end of the rotating cylinder 9, for driving the rotating cylinder 9 to rotate. One end of each of the two mounting plates 13 is rotatably provided with an upper rotating shaft 19 and a lower rotating shaft 14. The upper clamping plate 18 is fixedly arranged at the bottom end of the upper rotating shaft 19, and the lower clamping plate 15 is slidingly sleeved on the outer wall of the lower rotating shaft 14. A third servo motor 27 is fixedly arranged at the top of the upper mounting plate 13. The outer wall of the output shaft of the third servo motor 27 and the outer wall of the upper rotating shaft 19 are fixedly sleeved with synchronous wheels. The outer walls of the two synchronous wheels are drivingly sleeved with a same synchronous belt 20, for driving the upper clamping plate 18 to rotate.

[0031] With reference to Figure 5 A circular hole 17 is formed in the top of the outer ring 2, and a circular ring 16 is fixedly arranged on the inner wall of the circular hole 17. A plurality of rolling balls 24 are arranged on the bottom of the circular ring 16. When the lower clamping plate 15 moves to a specified position, the rolling balls 24 can reduce the friction between the rolling balls 24 and the circular ring 16, so as to ensure the rotation of the lower clamping plate 15. An inner rod 23 is fixedly arranged in the lower clamping plate 15, and the lower rotating shaft 14 is sleeved on the outer wall of the inner rod 23. A compression spring 22 is sleeved on the outer wall of the inner rod 23, and the two ends of the compression spring 22 are fixedly arranged on the inner wall of the lower clamping plate 15 and the top of the lower rotating shaft 14, respectively. When the lower clamping plate 15 moves to a specified position, the lower rotating shaft 14 can continue to move by extruding the compression spring 22.

[0032] Specifically, the second servo motor 25 is driven to rotate the rotating disc 4, thereby rotating the plastic bottle, and the rotating disc 4 is stopped when the work station groove 3 with the plastic bottle moves to the circular hole 17. At this time, the first servo motor 12 is driven to drive the two mounting plates 13 to move towards each other. The mounting plates 13 drive the lower clamping plate 15 and the upper clamping plate 18 to move through the lower rotating shaft 14 and the upper rotating shaft 19. The lower clamping plate 15 passes through the inside of the circular ring 16 and the circular hole 17, thereby clamping the plastic bottle from the bottom and the top. Then, the third servo motor 27 is driven to rotate the upper clamping plate 18, thereby rotating the clamped plastic bottle. At this time, the plasma surface treatment machine 6 is started to process the surface of the plastic bottle. The model of the plasma surface treatment machine can be a PM series plasma surface treatment machine. The working principle is that the surface of the plastic bottle is exposed to a high-energy plasma. The ions, electrons and free radicals in the plasma react with the material surface, thereby changing the properties and structure of the material surface. The treatment machine can quickly clean, activate, etch, finish and coat the material surface, thereby improving the adhesion, hydrophilicity, durability and wear resistance of the material.

[0033] When the height of the plastic bottle is low, the lower clamping plate 15 has not contacted the top after contacting the bottom. At this time, the mounting plate 13 can be continuously driven to move. When the lower clamping plate 15 is kept stationary by the compression spring 22, the lower rotating shaft 14 and the upper rotating shaft 19 can still continue to move, thereby driving the upper clamping plate 18 to continue to move downward, thereby achieving clamping. After the surface treatment is completed, the clamping mechanism 5 is reset, and then the second servo motor 25 and the conveyor 7 are continuously driven to perform the same operation.

[0034] The application can be applied to the field of plastic bottle production and other fields applicable to the application.

The top of the bottom column 1 is provided with a mounting groove. The second servo motor 25 is fixedly arranged in the mounting groove. The output shaft of the second servo motor 25 is fixedly arranged at the bottom of the rotating disc 4 and is used to drive the rotating disc 4 to rotate.
