DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1 , Figure 2 As shown, the utility model proposes a cylinder body inner hole dust removal device, including a conveying module 1, the conveying module 1 is a screw module, and a support frame 2 is provided on the slider of the conveying module 1. The conveying module 1 can move the support frame 2 to drive the support frame 2 to approach or move away from the cylinder 19 to be dusted; and in order to increase the stability of the support frame 2 when moving, support platforms are provided on both sides of the screw module, and rails 10 are provided on the support platform, and the two sides of the bottom of the support frame 2 are engaged with the rails 10.

[0022] The support frame 2 is provided with a lifting assembly 3, and the lifting assembly 3 includes a downward pressure cylinder 19 fixed to the top of the support frame, and the output end of the downward pressure cylinder 19 is connected to the slide plate 4, and the slide plate 4 is connected to the support frame 2 through the first slide rail 11. The contraction of the downward pressure cylinder 19 can drive the slide plate 4 to move up and down on the first slide rail 11, and its function is to adjust the position of the mounting plate 5 connected to the slide plate 4.

[0023] The bottom of the mounting plate 5 is provided with two sets of sliding components 6, such as Figure 2 , Figure 4 As shown, the sliding assembly 6 moves horizontally, and the sliding assembly 6 includes a driving screw 12, two sets of sliding blocks 13 slidably connected to the mounting plate 5, and the upper part of the sliding block 13 is connected to a roller 14. The slider of the driving screw 12 is provided with a push plate 15, and the push plate 15 is provided with an eight-shaped inclined hole 16. The roller 14 extends into the eight-shaped inclined hole 16. The sliding assembly 6 is respectively connected with a tubular member 7, one end of the tubular member 7 passes through the mounting plate 5 and is connected to the air inlet assembly 8, and the other end is connected to the air outlet head 9. The tubular member 7 passes through the sliding block 13 and a bearing 22 is provided therebetween. The tubular member 7 passes through the sliding block 13 and a bearing 22 is provided therebetween. The end of the member 7 is provided with a self-rotation drive assembly, which drives the tubular member 7 to rotate. Through the up and down movement of the push plate 15, the roller 14 is located in the eight-shaped inclined hole 16 and moves along the path of the eight-shaped inclined hole 16. At the same time, since the second slide rail 17 is horizontally arranged on the mounting plate 5, the sliding block 13 is engaged with the second slide rail 17, and the elastic member 18 is connected between the sliding blocks 13, the longitudinal movement of the slide plate 4 is restricted, and the slide plate 4 will move horizontally along the eight-shaped inclined hole and the second slide rail 17, forming the mutual approach or distance of the tubular member 7, which is used for adjustment according to the different positions of the hole of the cylinder 19. The elastic member 18 can be a spring, which is used to limit the movement between the two slide plates 4, ensure the stability of the sliding movement, and reduce the looseness caused by the assembly gap between the roller 14 and the eight-shaped inclined hole 16.

[0024] like Figure 3 As shown, the self-rotation drive assembly includes a cylinder 19 horizontally arranged on the mounting plate 5, the output end of the cylinder 19 is connected to a rack 20, the end of the tubular member 7 is provided with a gear 21, the rack 20 is meshed with the gear 21, and the rack 20 can be driven by the cylinder 19 to move, thereby driving the gear 21 to rotate, that is, the tubular member 7 connected to the gear 21 can be self-rotated, thereby ensuring that the gas is evenly distributed when blowing inside, thereby improving the dust removal effect.

[0025] like Figure 5 As shown, the end of the tubular member 7 is provided with an internal thread, the air outlet head 9 is threadedly connected to the tubular member 7, and the end of the air outlet head 9 is evenly distributed with air outlet holes 23, the air outlet holes 23 are arranged along the length direction of the tubular member 7, and the end is inclined. The inclined arrangement of the air outlet holes 23 is beneficial for blowing air toward the four inner walls of the cylinder body when exhausting air, thereby improving the dust removal effect.

[0026] The working mode of the device is as follows: after the cylinder 19 is transported to the dust removal station through the conveying line (not shown in the figure), the tubular member 7 is driven by the screw module to extend into the hole of the cylinder body of the cylinder 19. For alignment, the push plate 15 can be adjusted to make the tubular members 7 approach or move away from each other in the horizontal direction. After alignment, it extends into the cylinder body hole. At this time, the air intake assembly 8 connected to the end of the tubular member 7 blows air into the tubular member 7 and discharges it from the air outlet. Since the tubular member 7 extends into the cylinder body and is controlled to rotate by the self-rotation drive assembly, the inside of the cylinder body is evenly blown to remove dust.
