[0001] The invention relates to the technical field of anti-corrosion processing of metal products, and in particular to an anti-corrosion spraying device for metal products. Background Art

[0002] Anti-corrosion spraying of metal products is a commonly used anti-corrosion method. Its main purpose is to form a protective film on the metal surface to prevent the metal from corroding in contact with corrosive media. Commonly used anti-corrosion coatings include epoxy resin coatings, polyurethane coatings, acrylic coatings, etc. When spraying, the metal product needs to be placed on a fixture and then sprayed through the spraying equipment.

[0003] The applicant has found through retrieval that the anti-corrosion spray device for metal products needs to spray on both sides of the product during spraying, and both sides need to be dried after spraying. However, the existing spraying equipment is often unable to perform automatic adjustment of multiple metal products and continuous operation of drying after spraying. At the same time, it is also necessary to manually adjust the spraying or drying position, which leads to low efficiency. In addition, traditional spraying equipment cannot perform automatic quantitative spraying according to the needs of different products. Most of them manually control the spraying time, which is very inconvenient. At the same time, the sprayed anti-rust paint cannot be collected, resulting in waste of anti-rust paint.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0036] like Figure 1-Figure 10As shown, an anti-corrosion spraying device for metal products of the present invention comprises a device truncated table 1, a spraying chamber 11 is installed on the top of the device truncated table 1, a material box 15 is installed on the top surface of the top plate 12 of the spraying chamber 11, two spraying ports 13 and a hot air blower 14 are evenly arranged at the bottom of the top plate 12, the material box 15 is connected to a metering box 17 through two discharge pipes 16, a delivery pump 18 is fixed at the bottom of the metering box 17, the delivery pump 18 is located inside the spraying chamber 11 and docked with the spraying port 13, a motor 2, the motor 2 is located at the bottom center of the device truncated table 1, a square shaft 21 installed on the top of the motor 2 shaft passes through the device truncated table 1, a clamping adjustment part 3 and a quantitative control part 4 are installed on the square shaft 21, the clamping adjustment part 3 comprises a connecting rod 33 rotatably connected to the four sides of the square shaft 21, a fixture 34 is fixed at one end of the connecting rod 33 and a bevel gear 32 is fixed on the outer wall, the bevel gear 32 is meshed with the conical disc gear 31, and the conical The bottom of the disc tooth 31 is docked with the device truncated table 1 through four curved rods 116, and the four clamps 34 are all located below the two spray ports 13 and the hot air blower 14. The quantitative control part 4 includes a synchronous head 41 rotatably connected between the top plate 12 and the square shaft 21. The synchronous head 41 is connected to a synchronous head 2 43 through two synchronous belts 42. The synchronous head 2 43 docks with a valve stem 44 rotatably connected to the top surface of the top plate 12, and a valve 45 is installed inside the discharge pipe 16. When the valve stem 44 rotates 90°, it can drive the valve 45 to rotate 180° to complete a closing movement. A full gear 47 is fixed on the top of the valve stem 44, and a full gear 2 46 is meshed on one side of the full gear 47. The full gear 2 46 docks with the valve shaft connected to the bottom of the valve 45 and the discharge pipe 16. The diameter of the full gear 47 is larger than that of the full gear 2 46, and the full gear 1 47 rotates 90° to drive the full gear 2 46 to rotate 180°.

[0037] By designing the clamping adjustment part 3 and the quantitative control part 4, the present invention manually adds a proper amount of spraying liquid to a metering box 17 during the spraying operation, and then the clamp 34 at the bottom of the metering box 17 and the clamp 34 under the adjacent side hot air blower 14 each clamp a metal product, and then the delivery pump 18 under the metering box 17 is turned on, and all the liquid in the metering box 17 is sprayed out through the spraying port 13, and the spraying of one side of the metal product is completed, and the amount of liquid just meets the spraying demand. At this time, the motor 2 is started, the square shaft 21 rotates, and the connection The rod 33 drives the clamp 34 to move, and at the same time, the conical tooth 1 32 rotates on the conical disc tooth 1 31, and then drives the connecting rod 33 and the clamp 34 to rotate. After rotating 90°, the clamp 34 just flips 180°. At this time, the product that has just been sprayed is located under the next spray port 13, and the clamp 34 and the metal product located under the adjacent side of the hot air blower 14 are moved to the previous spray port 13, so that the work position and the spray angle are automatically adjusted. This reciprocating process, after the product is sprayed on both sides, it will automatically move to the two hot air blowers 14 for drying. , and the two sides can be dried in turn, and the metal products can be removed and placed after both sides are dried, and then the drying and spraying of both sides of the metal products and the continuous processing of multiple products can be completed. At the same time, when the square shaft 21 rotates 90°, the synchronous head 1 41 will also be driven to rotate 90°, so the synchronous head 2 43 can be driven to rotate through the two synchronous belts 42, and the synchronous head 2 43 can drive the valve stem 44 to rotate, and the full gear 1 47 rotates and meshes with the full gear 2 46, so that each time the valve stem 44 rotates 90°, the valve 45 rotates 18 0° completes a closing movement, then during operation, it is only necessary to design the rotation speed of the square shaft 21 to control the closing time of the valve 45 once, that is, the rotation speed of the square shaft 21 is inversely proportional to the liquid discharge speed of the discharge pipe 16. The faster the speed, the less the liquid discharge. After setting a suitable rotation speed, each time the square shaft 21 rotates to adjust the station, the discharge pipe 16 will introduce a suitable amount of anti-corrosion liquid from the material box 15 into the two metering boxes 17, and then all of it can be sprayed out through the delivery pump 18. There is no need to manually calculate the time to shut down the delivery pump 18, thereby improving production efficiency.

[0038] The device frustum 1 is provided with two fan-shaped openings below the two spray openings 13, and a fan-shaped filter frame 114 is installed on the inner wall of the fan-shaped opening. A recovery box 5 is provided at the position of the two filter frames 114 at the bottom of the device frustum 1. One side of the filter frame 114 is spaced a certain distance from the inner wall of one end of the fan-shaped opening to form a sewage outlet 111. A collecting box 51 is installed on one side of the recovery box 5, and the collecting box 51 is just located below the sewage outlet 111. Four brush plates 22 are installed on the outer wall of the square shaft 21. From the top view of the square shaft 21, the brush plate 22 and the connecting rod 33 are designed with an angle of 90°. An outer baffle 112 and an inner baffle 113 are provided on the top surface of the device frustum 1, and the outer baffle 112 and the inner baffle 113 are respectively located at the inner and outer sides of the two fan-shaped openings.

[0039] By designing the fan-shaped opening, the filter frame 114, the sewage outlet 111, the brush plate 22, the recovery box 5, the collection box 51, the outer baffle 112 and the inner baffle 113, some paint will be spilled each time spraying. At this time, the collection box 51 under the fan-shaped opening can collect the liquid to avoid paint waste. At the same time, the filter frame 114 can filter the dust that is mixed with the liquid in contact with the air. In addition, each time the work station is adjusted, the brush plate 22 will discharge the dirt filtered on its surface to the sewage outlet 11 through the filter frame 114. 1, and then discharged from the sewage outlet 111 into the collection box 51 to complete the secondary collection to avoid clogging of the filter frame 114. Finally, the outer baffle 112 and the inner baffle 113 can perform the role of limiting protection to prevent liquid dust from falling to other places during cleaning or filtering. It should be noted that in the design, after each adjustment of the work position, the brush plate 22 will be located at both ends of the fan-shaped opening, and the mesh plate of the filter frame 114 protrudes a little bit, that is, the brush of the brush plate 22 is in contact with the filter frame 114 but there is a little gap with the surface of the device cone 1.

[0040] The device table 1 and the motor 2 shaft are connected with a cleaning part 7, including three cleaning brush rollers 73 and three bevel teeth 72 rotatably connected to the two arc-shaped openings of the device table 1. The bevel teeth 72 are connected to the rotating shaft of the cleaning brush roller 73, and the three bevel teeth 72 are commonly engaged with a conical disc tooth 71. The conical disc tooth 71 is fixed on the motor 2 shaft and is located at the bottom of the device table 1. The three cleaning brush rollers 73 are all located below a hot air blower 14.

[0041] By designing the cleaning part 7, each brush plate 22 will be cleaned twice in one rotation, and the brush of the brush plate 22 after cleaning is very dirty, which affects the next cleaning. Therefore, when the square shaft 21 adjusts the station and rotates, the conical disc tooth 2 71 drives the three conical teeth 2 72 to rotate, and then drives the three cleaning brush rollers 73 to rotate. While the cleaning brush roller 73 rotates, it will contact the brush of the brush plate 22 passing by. Since the cleaning brush roller 73 is also higher than the surface of the device cone 1, the dirt on the brush of the brush plate 22 will be brushed off by the cleaning brush roller 73, and then the cleanliness of the brush plate 22 is effectively guaranteed, which is convenient for the brush plate 22 to continuously clean the filter frame 114. The brush plate 22 after cleaning is located in the drying area, that is, the position between the two hot air blowers 14, so it will dry quickly, which is convenient for the next cleaning.

[0042] A water tank 6 is placed at the position of the three cleaning brush rollers 73 at the bottom of the device cone 1. The interface on one side of the water tank 6 can be connected to the water inlet of the water pump 115 through a hose. The water pump 115 is installed at the top edge of the device cone 1. The water outlet of the water pump 115 can be connected to the interface of the humidifying pipe 117 through a hose. The humidifying pipe 117 is fixed on the side walls of the two curved rods 116, and three water outlet pipes for spraying water toward the surface of the cleaning brush roller 73 are installed at the bottom of the humidifying pipe 117. The interface where the humidifying pipe 117 and the water pump 115 are connected passes through the opening of the spray chamber 11.

[0043] By designing the water tank 6, the water pump 115 and the humidifying pipe 117, a filter can be installed at the upper end of the water surface inside the water tank 6. Then the water pump 115 can be started periodically to transport the water in the water tank 6 to the humidifying pipe 117 to spray water on the cleaning brush roller 73. At this time, the device is in a spraying and drying state. At this time, the dirt carried by the cleaning brush roller 73 due to the cleaning brush plate 22 can be flushed away, and the cleaned sewage enters the water tank 6 and is filtered by the filter. Furthermore, the cleaning brush roller 73 can be wetted to improve the cleaning effect, because the cleaning brush roller 73 is very easy to dry in the drying area.

[0044] Two placement frames 110 are installed on the inner wall of the spraying room 11, and the placement frames 110 are located below the two hot air blowers 14. The spraying room 11 is made up of four arc plates of the same specifications, and a glass window 19 is installed at the opening of each arc plate through a hinge axis. The positions of the four glass windows 19 correspond to the positions of the spray port 13 and the hot air blower 14.

[0045] By designing the placement frame 110 and the glass window 19, a recycling box can be placed in the placement frame 110 to receive a small amount of coating liquid that falls from the surface of the product due to hot air when the hot air blower 14 is drying, and the four glass windows 19 are convenient to open for placing and taking out metal products and taking out and placing recycling boxes in the placement frame 110. It should be noted that the hot air blower 14 runs through the top plate 12 in design, and the spray chamber 11 is formed by splicing four arc plates of the same specifications. At the same time, the arc plates and the top plate 12 are also detachable, which facilitates the subsequent cleaning and maintenance of the internal equipment and avoids the overflow of harmful gases during operation.

[0046] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
