It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms.

[0035] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, a high-efficiency spraying device for a glass-lined storage tank is provided, the device comprising:

[0036] The main frame 1 includes a mounting platform 101 disposed on the main frame 1, a guide platform 102 is fixedly mounted on the surface of the mounting platform 101, a plurality of guide wheels 103 are rotatably mounted on the inner wall of the guide platform 102, and a sliding plate 104 is also fixedly mounted on the surface of the mounting platform 101;

[0037] Spraying mechanism 2: comprising a spray head slider 204 slidably connected to the sliding plate 104, the surface of the spray head slider 204 is rotatably connected to a rotating gear 202, the surface of the rotating gear 202 is fixedly mounted with a spray head 201, the rotating gear 202 is meshed with a moving rack 203, and the rotating gear 202 is provided with incomplete teeth, the spray head slider 204 and the spray head screw 205 form a spiral pair transmission, the spray head screw 205 penetrates the interior of the mounting platform 101 and is rotatably connected to the mounting platform 101, the surface of the guide wheel 103 contacts the can body 206, and the surface of the can body 206 is fixedly mounted with four support seats 207;

[0038] Sliding mechanism 3: used to drive the spraying mechanism 2 to change the spraying direction;

[0042] In practical application, the embodiment of the present invention is as follows: Figure 1 As shown, when the can body 206 is sprayed, the can body 206 slides on the guide wheel 103 under the external thrust. When the can body 206 contacts the clamping mechanism 7, the clamping mechanism 7 clamps the can body 206. At the same time, under the action of the support seat 207, the sliding mechanism 3 moves to the position of the circumferential surface formed by the four support seats 207, so that the support seats 207 at different welding positions can be adapted, and the position of the support seat 207 is fully sprayed, which increases the versatility of the device. Figure 2 As shown, the can body 206 is driven upward by the action of the lifting mechanism 5. When it moves to the spraying position, the rotating mechanism 6 drives the can body 206 to rotate and spray. At the same time, the nozzle screw rod 205 is driven to rotate by the rotating mechanism 6, thereby driving the nozzle slider 204 to move horizontally. At this time, the spray head 201 starts to spray. When it is close to the support seat 207, as shown in FIG. Figure 4 and Figure 5 As shown, from Figure 5When the spraying is completed, the spray head 201 is reset by the action of the sliding mechanism 3. When the spraying is completed, the spray head 201 is reset by the action of the sliding mechanism 3. When the spraying is completed, the spray head 201 is reset by the action of the sliding mechanism 3. When the spraying is completed, the spray head 201 is reset by the action of the sliding mechanism 3. The spray head 201 returns to the vertical downward state to spray the tank body 206, thereby achieving the purpose of automatically and fully spraying the two sides of the support seat 207 and improving the spraying efficiency.

Fig.10 As shown, at this time, the sliding rod 301 slides along the fixed straight groove 312, and the spray head 201 sprays the surface of the can body 206. When it approaches the support seat 207, as shown in FIG. Figure 4 and Figure 5 As shown, from Figure 5When viewed from the front, the movable rack 203 enters the special-shaped slide rail 304 through the ascending groove 305, and moves downward first under the action of the reversing groove 306, at which time it drives the rotating gear 202 to rotate counterclockwise, thereby driving the spray head 201 to rotate counterclockwise. At this time, the left side of the support seat 207 is fully sprayed. After the left side is sprayed under the action of the inclined spraying groove 307, the movable rack 203 is driven upward by the action of the reversing groove 308. At this time, the rotation of the rotating gear 202 drives the spray head 201 to reset. When the support seat 207 is When the left side comes to the right side, the spray head 201 rotates clockwise under the action of the reversal groove 308 to fully spray the right side of the support seat 207. After spraying, it is reset through the action of the recovery groove 310, and returns to the fixed straight groove 312 again through the descending groove 311. It should be noted here that the sliding rod 301 and the compression spring 302 are arranged so that the sliding rod 301 is always limited by the fixed straight groove 312 and the special-shaped slide rail 304, avoiding the abnormal phenomenon of separation from the slide groove, thereby achieving the purpose of fully spraying the support seat 207.

When the tank body 206 stops moving, the special-shaped slide rail 304 is located vertically above the circumferential surface where the four support seats 207 are located. When the tank body 206 moves upward, the sliding sleeve 402 is limited by the locking device on the fixed rod 404, thereby limiting the position of the special-shaped slide rail 304, so as to achieve the purpose of automatically adjusting the position of the special-shaped slide rail 304, so as to correspond to the position of the support seat 207, and ensure that the spray head 201 is always rotated in the spraying direction close to the two sides of the support seat 207, so as to fully spray the support seat 207.

[0052] In practical application, the embodiment of the present invention is as follows: Figure 3 and Figure 6 As shown, from Figure 6 When viewed from the front, when the can body 206 moves along the guide wheel 103 until the left end of the can body 206 touches the clamping claw ring 701, the can body 206 stops moving and drives the clamping claw ring 701 to move to the left under the action of external tension. At this time, the clamping claw ring 701 drives the expansion claw 703 to expand inside the can body 206 through the tension rod 702, thereby fixing the can body 206 through the cooperation of the clamping claw ring 701 and the expansion claw 703.
