[0018] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0019] Example 1: This example provides an anti-corrosion spraying device for bolt processing, such as... Figure 1 As shown, when spraying bolts, the spraying device needs to control the up and down movement of the nozzle and the rotation of the bolts to achieve all-round spraying. Therefore, the bolt spraying process is quite troublesome. The spraying box 1 has an adjustable base frame 2 on its inner bottom wall. Several lower rotating cylinders 3 are rotatably inserted into the adjustable base frame 2. The inner top wall of the spraying box 1 has an adjustable spraying frame 4. The inner top wall of the spraying box 1 has an upper rotating cylinder 5 corresponding to the number of lower rotating cylinders 3. The end of the adjustable spraying frame 4 is movably sleeved on the upper rotating cylinder 5. The outer wall of the upper rotating cylinder 5 has a spiral groove 6. The end of the adjustable spraying frame 4 is provided with a guide block 7, which slides with the inner wall of the spiral groove 6.

[0020] First, the bolt is placed into the lower rotating cylinder 3. Then, the adjustable base frame 2 pushes the lower rotating cylinder 3 and the bolt upward. At this time, the upper rotating cylinder 5 abuts and limits the upper end of the bolt, thereby clamping and fixing the bolt by the cooperation of the upper rotating cylinder 5 and the lower rotating cylinder 3. Then, the adjustable spray frame 4 moves up and down to spray the surface of the bolt. At the same time, the adjustable spray frame 4 drives the guide block 7 to slide along the inner wall of the spiral groove 6 to make the upper rotating cylinder 5 rotate. Then, the upper rotating cylinder 5 drives the bolt to rotate, and the adjustable spray frame 4 sprays the bolt surface in all directions.

[0021] Combination Figure 2 In an embodiment of this utility model, a feeding device 11 is provided on the top of the spray box 1. The discharge end of the feeding device 11 is inserted into the spray box 1 and connected to the adjustable spray frame 4. The feeding device 11 facilitates the supply of spray paint to the adjustable spray frame 4.

[0022] Combination Figure 2 In an embodiment of this utility model, the adjustable base frame 2 includes a first electric push rod 21 and a base plate 22. The first electric push rod 21 is fixedly installed on the inner bottom wall of the spray box 1, and the base plate 22 is fixedly installed on the extended end of the first electric push rod 21. Several lower rotating cylinders 3 are evenly distributed in a ring on the base plate 22. The first electric push rod 21 facilitates the control of the base plate 22 to move up and down, and then the base plate 22 drives the lower rotating cylinders 3 and bolts to move up and down.

[0023] A sealing ring 12 is fixedly installed on the inner bottom wall of the spray box 1, and the bottom plate 22 is movably inserted into the sealing ring 12.

[0024] Example 2: Reference Figure 2 , Figure 3 The top of the lower rotating cylinder 3 is provided with a slot 31, and several suction cups 32 are fixedly inserted into the inner bottom wall of the slot 31. The slot 31 facilitates the operator to insert the bolt into the lower rotating cylinder 3 and to use the suction cups 32 to adsorb the bolt, thereby reducing the possibility of the bolt falling off when the base plate 22 moves the lower rotating cylinder 3.

[0025] A piston chamber 33 is provided at the bottom of the lower rotating cylinder 3. A piston plate 34 is movably disposed in the piston chamber 33. The piston plate 34 is connected to the inner wall of the piston chamber 33 by a spring 35. The air inlet end of the suction cup 32 passes through the slot 31 and is inserted into the piston chamber 33. When the bottom plate 22 moves upward, it separates from the sealing ring 12. At this time, the spring 35 pushes the piston plate 34 to move, thereby causing the suction cup 32 to be in a negative pressure state. Then, the suction cup 32 is used to adsorb and fix the bolt. When the bottom plate 22 is inserted into the sealing ring 12, the airflow in the sealing ring 12 is injected into the piston chamber 33. Under the action of the airflow, the piston plate 34 is pushed to reset, so that the suction cup 32 loses its suction force.

[0026] Example 3: Reference Figure 2 , Figure 4 The adjustable spraying frame 4 includes a second electric push rod 41 and a diverter plate 42. The second electric push rod 41 is fixedly installed on the inner top wall of the spraying box 1, and the diverter plate 42 is fixedly installed at the extended end of the second electric push rod 41. The discharge end of the feeding device 11 is connected to the inlet end of the diverter plate 42. Several spraying heads 43 are fixedly inserted into the outer wall of the diverter plate 42. The discharge end of the spraying head 43 corresponds to the position of the upper rotating drum 5. The outer wall of the diverter plate 42 is fixedly provided with guide plates 44 in a number corresponding to the upper rotating drum 5. The second electric push rod 41 facilitates the movement of the diverter plate 42 and the spraying heads 43 up and down, so that the surface of the bolt is sprayed by the spraying head 43. As the diverter plate 42 moves, the guide plate 44 moves synchronously. At this time, the guide plate 44 drives the guide block 7 to slide along the inner wall of the spiral groove 6, so as to cause the upper rotating drum 5 to rotate the bolt, so that the spraying head 43 can spray the bolt surface in all directions.

[0027] The guide plate 44 includes a connecting plate 441 and a ring 442. One end of the connecting plate 441 is fixedly connected to the diverter plate 42, and the other end of the connecting plate 441 is fixedly connected to the ring 442. The guide block 7 is fixedly disposed on the inner side of the ring 442. The ring 442 is movably sleeved on the upper rotating cylinder 5. When the diverter plate 42 moves, it drives the connecting plate 441, the ring 442 and the guide block 7 to move synchronously. At this time, the guide block 7 slides along the inner wall of the spiral groove 6 to control the rotation of the upper rotating cylinder 5.

[0028] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
