Description

Technical Field

[0001] This utility model relates to the field of galvanized pipe production technology, specifically to a spraying equipment for galvanized pipe production. Background Technology

[0002] Galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mining, chemical industry, power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, mining machinery, and greenhouse construction. Galvanized steel pipes are welded steel pipes with a hot-dip galvanized or electro-galvanized coating. Galvanizing increases the corrosion resistance of the steel pipe and extends its service life. Before use, to prevent corrosion during operation, the outer surface of the galvanized pipe needs to be sprayed with an anti-corrosion material.

[0003] A search revealed a patent with application number CN202420162826.7, which discloses a spraying device for galvanized pipe production. The device includes a base plate with a housing fixedly connected to its top. An electric slide rail is fixedly installed on the top of the base plate and inside the housing. A support plate is mounted on the electric slide rail. However, in practical use, the aforementioned patent has the following drawbacks: it cannot perform all-around spraying of galvanized pipes, resulting in low spraying efficiency. Therefore, we propose a spraying device for galvanized pipe production. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In the spraying mechanism of this utility model, multiple atomizing nozzles are equidistantly arranged around the inner wall of the annular tube, enabling spraying of the galvanized pipe from multiple directions, achieving an all-around spraying effect and improving the spraying quality. Simultaneously, the annular tube can be moved left and right by a sliding slider, allowing spraying of different positions on the galvanized pipe, making operation convenient and improving spraying efficiency.

[0014] 2. This utility model, by setting up a first lead screw, a second lead screw, threaded blocks, a fixing frame, an electric push rod, and a clamping plate, uses two threaded blocks driven by a servo motor to move the fixing frame closer or further apart, since the first and second lead screws have opposite thread directions. This allows for easy adjustment and fixing according to the length of the galvanized pipe. In conjunction with the electric push rod pushing the clamping plate, the galvanized pipe can be firmly fixed on the fixing frame, preventing the galvanized pipe from shaking during the spraying process and ensuring the stability of the spraying.

A first lead screw 5 is fixedly connected to the output end of the servo motor 4. The right end of the first lead screw 5 passes through the fixed seat 2 and the guide groove 3 in sequence and extends into the interior of the guide groove 3 and is fixedly connected to a second lead screw 6. The right end of the second lead screw 6 is rotatably connected to the inner wall of the guide groove 3 through a bearing. A spraying mechanism 7 is provided on the fixed seat 2.

[0024] Specifically, threaded blocks 8 are threadedly connected to the surfaces of the first lead screw 5 and the second lead screw 6. The threads of the first lead screw 5 and the second lead screw 6 are in opposite directions. The top and bottom of the threaded blocks 8 are in movable contact with the inner wall of the guide groove 3. The threaded blocks 8 are made of wear-resistant cast iron. The top and bottom of the threaded blocks 8 are in sliding fit with the inner wall of the guide groove 3, which ensures the smooth movement of the threaded blocks. The front side of the threaded blocks 8 passes through the guide groove 3 and extends to the outside of the guide groove 3 and is fixedly connected to a fixing frame 9. An electric push rod 10 is fixedly connected to the top of the fixing frame 9. The telescopic end of the electric push rod 10 passes through the fixing frame 9 and extends into the inside of the fixing frame 9 and is fixedly connected to a pressure plate 11.

[0025] In specific implementation, the spraying mechanism 7 includes a chute 701, a slide column 702, a slider 703, a handle 704, a connecting block 705, an annular tube 706, a paint tank 707, a feeding pipe 708, a delivery pump 709, a delivery hose 710, and an atomizing nozzle 711. A chute 701 is provided on the upper front side of the fixed base 2, and the left and right sides of the inner wall of the chute 701 are slidably connected by the slide column 702.

[0026] Specifically, a slider 703 is slidably sleeved on the surface of the sliding column 702. The slider 703 is made of tin bronze, which has good wear resistance and self-lubrication. The front side of the slider 703 passes through the sliding groove 701 and extends to the outside of the sliding groove 701 and is fixedly connected to a handle 704. A connecting block 705 is fixedly connected to the bottom of the slider 703, and an annular tube 706 is fixedly connected to the bottom of the connecting block 705.

[0027] In practical implementation, a paint tank 707 is fixedly connected to the top front side of the base 1. A feeding pipe 708 is fixedly installed on the left side of the top of the paint tank 707. A delivery pump 709 is fixedly connected to the top of the paint tank 707. The delivery pump 709 is a DBY-10 diaphragm pump with an adjustable flow rate of 0-5L / min and an operating temperature range of -10℃ to 60℃. It can deliver various corrosive and high-viscosity paints.

[0028] Specifically, a material extraction pipe is fixedly connected to the bottom of the delivery pump 709, the bottom of which penetrates through the paint tank 707 and extends into the interior of the paint tank 707, and a delivery hose 710 is fixedly connected to the top of the delivery pump 709.

[0030] In practical application: During use, based on the length of the galvanized pipe, the servo motor 4 is started. The servo motor 4 drives the first lead screw 5 and the second lead screw 6 to rotate. Since the threads of the first lead screw 5 and the second lead screw 6 are in opposite directions, the two threaded blocks 8 will cause the fixing brackets 9 to move closer or further apart. After adjusting the fixing brackets 9 to a suitable position, the galvanized pipe is placed through the two fixing brackets 9. The electric push rod 10 is started, which pushes the clamping plate 11 downward to press and fix the galvanized pipe. Then, paint is added to the paint tank 707 through the feeding pipe 708. The delivery pump 709 is started, and the delivery pump 709 draws the paint out of the paint tank 707 through the extraction pipe, and delivers it to the annular pipe 706 through the delivery hose 710. Then, it is atomized and sprayed out through multiple atomizing nozzles 711 to spray the galvanized pipe. During the spraying process, the operator can push the handle 704, causing the slider 703 to slide left and right along the sliding column 702, thereby moving the annular tube 706 left and right, achieving all-round spraying of different positions of the galvanized pipe, improving spraying efficiency and quality.
