Description

Technical Field

[0001] This utility model relates to the field of door leaf production and processing technology, and in particular to an automatic rust-preventive liquid spraying device for door leaf production. Background Technology

[0002] After the door panel is welded, the potential difference accelerates corrosion at the weld anode, and the porous structure formed by high-temperature oxidation in the weld area makes it more susceptible to absorbing moisture and oxygen, becoming a starting point for rust. Therefore, during the door panel manufacturing process, the welded areas are cleaned and sprayed with rust inhibitor to extend the door panel's lifespan.

[0003] Currently, rust-preventive spraying at the welded joints of door panels is generally done manually. During cleaning, it is difficult to control the use of wire brushes to efficiently and reliably remove rust and scale from the welded joints. This process is labor-intensive and inefficient, which in turn affects subsequent processing steps and is detrimental to the production efficiency of door panels. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic rust-preventive liquid spraying device for door leaf production. This device can automatically and efficiently clean the welding positions of door leaves, which not only improves work efficiency but also facilitates the subsequent rust-preventive liquid spraying effect.

[0020] Example 1

[0021] like Figure 1 - Figure 4As shown in the figure, the automatic rust-preventive liquid spraying device for door leaf production proposed in this embodiment includes a mounting frame 1 and a cleaning mechanism; a conveying seat 2 is provided on the inner side of the mounting frame 1. Both the mounting frame 1 and the conveying seat 2 are set on a base with a linear conveying mechanism. The conveying seat 2 is used to fix and place the doors and windows after welding.

[0022] The cleaning mechanism includes a drive assembly mounted on the mounting frame 1, a mounting plate 5 mounted on the drive assembly, a motor 6 mounted on the mounting plate 5, a rotating shaft 7 rotatably connected to the mounting plate 5, a turntable 8 coaxially mounted on the rotating shaft 7, a wire brush 9 mounted on the turntable 8, and a positioning assembly mounted on the mounting plate 5.

[0023] The drive assembly includes a cylinder 3 mounted on a mounting frame 1 and a connecting frame 4 driven by the cylinder 3. A mounting plate 5 is mounted on the connecting frame 4. A motor 6 and a rotating shaft 7 are driven and connected. A support rotating cylinder 10 is coaxially mounted on a turntable 8. The end of the support rotating cylinder 10 away from the turntable 8 is rotatably mounted inside the mounting plate 5.

[0024] The positioning assembly includes two fixed cylinders 11 symmetrically distributed on the mounting plate 5, a spring 12 disposed inside the fixed cylinder 11, a telescopic rod 13 slidably connected to the fixed cylinder 11, a frame 14 disposed on the telescopic rod 13, and a roller 15 rotatably connected to the frame 14. The end of the telescopic rod 13 away from the frame 14 is disposed on the spring 12. Four limiting sliders 16 are disposed on the telescopic rod 13 in a circular array. The fixed cylinder 11 is provided with a guide groove 17 for the horizontal sliding of the limiting sliders 16. The limiting sliders 16 and the guide groove 17 not only play a positioning and limiting role in the movement distance of the mounting plate 5, but also prevent the telescopic rod 13 from bending or twisting, ensuring the stability of the frame 14 while preventing the spring 12 from bending or twisting.

[0025] In this embodiment, when cleaning the welded area of ​​the door leaf to improve the effect of subsequent rust-preventive spraying, as the conveyor seat 2 transports the door leaf to the inside of the mounting frame 1, the cylinder 3 is activated to drive the connecting frame 4 to move. The connecting frame 4 drives the mounting plate 5 and the cleaning mechanism to move. The roller 15 first contacts the door leaf and continuously pushes the telescopic rod 13 to retract. At the same time, the telescopic rod 13 continuously compresses the spring 12. As the mounting plate 5 continues to move, the wire brush 9 will contact the door leaf and the welded area. When the limit slider 16 abuts against the guide groove 17, the squeezing action between the wire brush 9 and the welded area is at the optimal state tested during debugging. Then, the motor 6 is activated to drive the rotating shaft 7 to rotate. The rotating shaft 7 drives the turntable 8 to rotate, thereby cleaning the welded area with the wire brush 9 to remove impurities such as welding slag and oxide scale, thereby improving the effect of subsequent rust-preventive spraying. At the same time, as the conveyor seat 2 moves, the wire brush 9 cleans the welded area. The roller 15 rolls along the door leaf under the elastic compensation of the spring 12 to avoid affecting normal transport, which has good practicality.

[0026] Example 2

[0027] like Figure 1 and Figure 2 As shown in the figure, the automatic rust-preventive liquid spraying device for door leaf production proposed in this embodiment, compared with the first embodiment, has a suction arm 18 on the mounting plate 5, a collection box 20 on the mounting frame 1, a conduit 19 connecting the suction arm 18 and the collection box 20, a collection box 22 below the mounting plate 5, a connecting block 21 on the collection box 22, and a guide rail for sliding the connecting block 21 on the mounting plate 5.

[0028] A bolt 23 is provided through the mounting plate 5, and the bolt 23 is threaded onto the connecting block 21.

[0029] In this embodiment, after the cleaning mechanism cleans the welding slag and oxide scale at the welding position, the negative pressure generated by the collection box 20 causes the suction arm 18 to generate suction, thereby sucking up the welding slag and other impurities and transporting them to the inside of the collection box 20 through the conduit 19. During the cleaning process, some impurities will fall off, and the collection box 22 can collect the fallen impurities to avoid damaging the working environment. When the collection box 22 needs to be processed, the bolt 23 is removed from the connecting block 21 and the mounting plate 5, and then the connecting block 21 is removed from the guide rail to complete the disassembly of the collection box 22. The operation is simple and convenient.

[0030] Example 3

[0031] like Figure 1 As shown in the figure, the automatic rust-preventive liquid spraying device for door leaf production proposed in this embodiment has an additional feature compared to the first embodiment. In this embodiment, the mounting frame 1 is provided with a mounting base 24 and a barrel 26. The mounting base 24 is provided with a spray gun 25. A liquid guide pipe 27 is provided between the spray gun 25 and the barrel 26. The spray gun 25 can be adjusted in spray position through the mounting base 24.

[0032] In this embodiment, the inside of the barrel 26 is used to store rust inhibitor. After the welding position is cleaned by the cleaning mechanism, the rust inhibitor is transported along the liquid guide pipe 27 by the pump and then sprayed onto the welding position by the spray gun 25 to ensure the service life of the door leaf.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
