Description

Technical Field

[0001] This utility model relates to the field of metal processing, specifically to a spraying device for non-ferrous metal rolling processing. Background Technology

[0002] Non-ferrous metals refer to all metals other than iron, chromium, and manganese. These metals have important applications in modern industry.

[0003] In order to adapt metal products to the needs of different fields, the non-ferrous metal processing process requires non-ferrous metal materials to be processed into the required shapes and specifications through processes such as rolling, stretching, and extrusion. This process is called non-ferrous metal rolling, which is to further improve the strength, plasticity and toughness of the metal. Before metal rolling, a coating treatment needs to be applied to the surface of the metal products to improve their corrosion resistance, aesthetics and other properties. For non-ferrous metals, spraying can not only improve the appearance quality, but also provide functions such as corrosion resistance and wear resistance.

[0004] During the spraying process of non-ferrous metal sheets, the spraying material that exceeds the portion of the non-ferrous metal sheet is directly splashed onto the spraying table, which not only wastes material but also affects the efficiency of subsequent spraying. The spraying material is inconvenient to clean and wipe off, and the metal sheet is not dried in time after spraying, which accelerates the drying speed of the spraying material. Utility Model Content

[0005] To address the technical problems mentioned above, during the spraying process of non-ferrous metal sheets, the spraying material exceeding the sheet material directly splashes onto the spraying table, which not only wastes material and affects subsequent spraying efficiency, but also makes the spraying material inconvenient to clean and remove, and fails to dry the metal sheet in time after spraying to accelerate the drying speed of the spraying material, this utility model provides a spraying device for non-ferrous metal rolling processing.

[0006] A spraying device for non-ferrous metal rolling processing includes an outer frame, an electric slide rail fixedly mounted on the bottom wall of the outer frame, a movable frame slidably mounted on the electric slide rail, a bidirectional lead screw rotatably mounted on the movable frame, a limit baffle threaded to the outer wall of the bidirectional lead screw, a spraying unit and a drying unit fixedly mounted on the top wall of the outer frame, the spraying unit including a raw material box and a telescopic rod, and several nozzles communicating with the raw material box, the nozzles being fixedly mounted on the telescopic end of the telescopic rod via connecting plates, the drying unit including a drying chamber, and a blower and several electric heating rods installed inside the drying chamber.

[0007] More preferably, an electric slider is slidably mounted on the electric slide rail, and a movable frame is fixedly mounted on the top wall of the electric slider. The top wall of the movable frame is provided with a support block and a groove. The support block can be used to support the metal body. A bidirectional lead screw is rotatably mounted on the inner wall of the groove, and one end of the screw passes through the groove and is fixedly mounted with an adjustment knob.

[0008] More preferably, there are two limiting baffles, symmetrically arranged on the outer wall of the bidirectional lead screw. The top of both limiting baffles is inclined, and the inclination direction is outward, which can block the spraying material from splashing out during the spraying process.

[0009] More preferably, the telescopic rod and the raw material box are fixedly installed on the inner top wall and outer top wall of the outer frame, respectively. The connecting plate is fixedly installed on the telescopic end of the telescopic rod. Several nozzles are connected to the raw material box through the conveying pipe. Several nozzles are fixedly installed on the connecting plate. The conveying pipe includes a telescopic pipe and a conventional pipe that are connected to each other. A pump body is installed on the conventional pipe.

[0010] More preferably, the bottom wall of the drying oven is configured with a ventilation mesh structure, the blower is an electric blower fixedly installed on the top wall of the drying oven, and several electric heating rods are fixedly installed on the inner wall of the drying oven below the blower.

[0011] Compared with existing technologies, the advantages of this invention are as follows: After placing the metal sheet on the support block, turning the adjustment knob causes the two limiting baffles to close together, clamping the metal sheet. Furthermore, the outwardly tilted tops of the limiting baffles guide the sprayed material splashed during the spraying process to the surface of the metal sheet below, preventing it from splashing onto the moving frame, thus ensuring cleanliness and preventing waste of sprayed material. After spraying, the sheet is promptly moved to the drying unit, where a fan blows heat generated by the electric heating rod onto the surface of the metal sheet, accelerating the drying speed of the sprayed material.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. The following will refer to the accompanying drawings. Figures 1-3 The present invention will be described in detail with reference to the embodiments.

[0021] A spraying device for non-ferrous metal rolling processing includes an outer frame 1. An electric slide rail 2 is fixedly installed on the bottom wall of the outer frame 1. A movable frame 3 is slidably installed on the electric slide rail 2. An electric slider 13 is slidably installed on the electric slide rail 2. The movable frame 3 is fixedly installed on the top wall of the electric slider 13. A support block 14 and a groove 15 are provided on the top wall of the movable frame 3. The support block 14 can be used to support the metal body. Both the electric slide rail 2 and the electric slider 13 are electrically connected to an external power source. After the power is turned on, the electric slider 13 can move along the direction of the electric slide rail 2, thereby driving the metal sheet placed above to move in and out of the outer frame 1. This allows the metal sheet to pass through the spraying unit to complete the spraying, and after the drying unit completes the drying, it is moved to the outside of the outer frame 1 for collection.

[0022] A bidirectional lead screw 4 is rotatably mounted on the movable frame 3. A limit baffle 5 is threadedly connected to the outer wall of the bidirectional lead screw 4. The bidirectional lead screw 4 is rotatably mounted on the inner wall of the groove 15, and one end of it passes through the groove 15 and is fixedly mounted with an adjustment knob 16.

[0023] Place the metal sheet on the support block 14, then turn the adjusting knob 16 to rotate the bidirectional lead screw 4, which in turn causes the two limiting baffles 5 to close together, approaching the metal sheet and clamping it. Since there are two limiting baffles 5, symmetrically arranged on the outer wall of the bidirectional lead screw 4, and the tops of both limiting baffles 5 are inclined outwards, they can block the spray material from splashing out during the spraying process. When spraying, the inner part of the spray material sprayed from the nozzle 7 directly hits the surface of the metal sheet, while some of the outer part may splash to the outside. At this time, since the top of the limiting baffle 5 is inclined outwards, it can block the splashed material and make it fall onto the surface of the metal sheet along the inclined direction, which can not only avoid material waste, but also keep the table clean.

[0024] A spraying unit and a drying unit are fixedly installed on the top wall of the outer frame 1. The spraying unit includes a raw material box 6 and a telescopic rod 8, and several nozzles 7 connected to the raw material box 6. The nozzles 7 are all fixedly installed on the telescopic end of the telescopic rod 8 through a connecting plate 9. The telescopic rod 8 and the raw material box 6 are respectively fixedly installed on the inner top wall and the outer top wall of the outer frame 1. The connecting plate 9 is fixedly installed on the telescopic end of the telescopic rod 8. The nozzles 7 are connected to the raw material box 6 through a conveying pipe 17. The nozzles 7 are fixedly installed on the connecting plate 9. The conveying pipe 17 includes a telescopic pipe 18 and a conventional pipe 19 that are connected to each other. A pump body 20 is installed on the conventional pipe 19.

[0025] The distance between the nozzle 7 and the metal sheet is adjusted according to the thickness of the metal sheet to ensure that it is within a suitable spraying range. When the moving frame 3 below moves, the material hopper sprayed by the nozzle 7 falls between the two limiting baffles 5. The telescopic rod 8 is activated, which drives the connecting plate 9 to move downward, thereby driving several nozzles 7 to move downward to a certain distance and then stop. The telescopic pipe 18 can extend and retract according to the up and down movement of the telescopic rod 8.

[0026] As the metal sheet moves with the moving frame 3 to the bottom of the spraying unit, the pump body 20 is started, so that the spraying material inside the material box 6 can be transported through the conveying pipe 17 to several nozzles 7, and the metal sheet is sprayed through the nozzles 7.

[0027] The drying unit includes a drying chamber 10, inside which is installed a blower 11 and several electric heating rods 12. The bottom wall of the drying chamber 10 is configured with a ventilation mesh structure. The hot air generated inside the drying chamber 10 can be blown onto the metal plate below through the ventilation mesh structure. The blower 11 is an electric blower and is fixedly installed on the top wall of the drying chamber 10. Several electric heating rods 12 are fixedly installed on the inner wall of the drying chamber 10 below the blower 11.

[0028] The coated metal sheet continues to move along the moving frame 3 to the drying unit. Simultaneously, the blower 11 and electric heating rod 12 are activated, allowing the heating rod 12 to generate heat. The blower 11 then evenly distributes this heat onto the metal sheet below, accelerating the drying of the coating material. After the metal sheet has been coated and dried, it moves along the moving frame 3 to the other end of the electric slide rail 2. The clamps on the metal sheet are then released, allowing the operator to remove it for transfer. The other side is then coated, followed by the rolling process.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
