Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a sheet metal painting device. Background Technology

[0002] Sheet metal parts refer to products processed through sheet metal technology. Sheet metal is a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / compound cutting, bending, welding, riveting, splicing, forming, etc. Its significant feature is that the thickness of the same part is uniform. After the sheet metal parts are formed, their outer surface is painted to give them the functions of rust prevention, water resistance and extended service life.

[0003] The patent for sheet metal processing and coating equipment, with announcement number CN221183366U, includes a coating box. A paint spraying device is mounted on the upper end of the coating box, and a paint collection device is slidably mounted on the lower end. Sheet metal fixing devices are installed on the left and right outer walls of the coating box, located between the paint spraying device and the paint collection device. This utility model, by installing a paint spraying device, allows the spraying moving component to drive the storage box and nozzle to move back and forth, improving the uniformity and area of ​​the sprayed paint on the clamped sheet metal. The paint collection device, with its filter plate, filters dripping paint, preventing it from carrying impurities adhering to the sheet metal and subsequently spraying them onto the sheet metal workpiece, thus reducing the quality of the sheet metal coating. The collection hopper collects the paint and can be detached via a sliding strip, facilitating the pouring of collected paint into a paint tank for reuse, improving resource utilization and reducing costs.

[0004] However, in this prior art, when painting sheet metal parts, the sheet metal parts need to be positioned and clamped before they can be painted. Since the sheet metal parts are clamped by the clamping head, it is not convenient to paint the clamped parts, resulting in incomplete painting.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a sheet metal painting device that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted:

[0008] A sheet metal painting apparatus includes: a machine base; a paint spray head disposed on the machine base; a pusher assembly for moving the sheet metal parts to perform painting operations; and a centering assembly for centering the pushed sheet metal parts.

[0009] The feeding assembly includes: a push plate slidably mounted on the machine base; movable rods fixedly mounted on both ends of the push plate; and an electric push rod that drives the movable rods to move, wherein the electric push rod is fixedly mounted on the bottom of the machine base.

[0010] One end of the machine is also equipped with a drying component for drying the painted sheet metal parts.

[0011] Furthermore, a guide sleeve is slidably mounted on the top of the movable rod, and the top of the guide sleeve is fixedly mounted on the bottom of the machine base.

[0012] Furthermore, the centering assembly includes: a positioning plate slidably mounted on both sides of the machine base; a guide rod for guiding the movement of the positioning plate; and a spring fitted on the guide rod, with one end of the spring fixedly connected to the surface of the positioning plate and the other end of the spring fixedly mounted on the machine base.

[0013] Furthermore, one side of the lower end of the positioning plate is arc-shaped, and the end of the movable rod near the adjacent positioning plate is inclined.

[0014] Furthermore, several guide rollers are equidistantly mounted on one side of the upper end of the positioning plate.

[0015] Furthermore, the drying assembly includes: a roller conveyor line disposed at one end of the machine platform; and a drying chamber located in the middle of the roller conveyor line.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In the sheet metal painting process, the sheet metal is pushed and painted by the pusher component, and the centering component ensures that the pushed sheet metal is always centered, preventing excessive skew during the pushing of the sheet metal, which would prevent the parts outside the painting range from being effectively painted. This avoids the problem of incomplete painting caused by the need to clamp the sheet metal in the existing painting device, which makes it difficult to paint the clamped parts. Thus, the painting quality is guaranteed. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0025] like Figures 1 to 4 As shown, this utility model discloses a sheet metal painting device, comprising: a machine base 1; a paint spray head 2 mounted on the machine base 1, with an external infusion pump connected to the upper end of the paint spray head 2, through which paint is delivered to the inside of the paint spray head 2 for painting the sheet metal parts; a pusher assembly 3 for moving the sheet metal parts to perform the painting operation; and a centering assembly 4 for centering the pushed sheet metal parts.

[0026] The material pushing assembly 3 includes: a push plate 301 slidably mounted on the machine base 1; movable rods 302 fixedly mounted on both ends of the push plate 301; and an electric push rod 303 that drives the movable rods 302 to move. The electric push rod 303 is fixedly mounted on the bottom of the machine base 1, and the two electric push rods 303 can be synchronously raised and lowered through parameter settings.

[0027] Place the sheet metal part to be painted on the machine base 1; start the electric push rod 303; the output end of the electric push rod 303 retracts, and drives the movable rod 302 to move towards the positioning plate 401, pushing the sheet metal part placed on the machine base 1 to the bottom of the paint head 2 for painting, so that the side to be painted can be painted evenly, preventing the existing painting device from having difficulty painting the clamped part due to the need to clamp the sheet metal part, resulting in incomplete painting, thus ensuring the painting quality.

[0028] One end of the machine is also equipped with a drying component 5 for drying the painted sheet metal parts.

[0029] It should be added that a guide sleeve 3021 is slidably installed on the top of the movable rod 302, and the top of the guide sleeve 3021 is fixedly installed on the bottom of the machine base 1; the guide sleeve 3021 improves the stability of the movement of the movable rod 302.

[0030] To prevent the sheet metal parts from skewing during pushing, the centering assembly 4 includes: positioning plates 401 slidably mounted on both sides of the machine base 1; guide rods 402 guiding the movement of the positioning plates 401; and springs 403 fitted onto the guide rods 402, with one end of the springs 403 fixedly connected to the surface of the positioning plates 401 and the other end fixedly mounted on the machine base 1. It should be noted that the machine base 1 has moving slots on both sides, with the guide rods 402 horizontally fixedly mounted in the moving slots. The other end of the springs 403 is fixedly mounted on the side wall of the moving slots. When the bottom of the positioning plates 401 is released from pressure against one end of the moving rods 302, the springs 403 elastically reset under force, pushing the positioning plates 401 to their initial position and releasing the centering guidance for the sheet metal parts.

[0031] When the output end of the electric push rod 303 retracts, driving the movable rod 302 to move, the inclined surface of one end of the movable rod 302 presses against the arc surface of the lower end of the positioning plate 401, thereby pushing the positioning plate 401 closer to one side of the sheet metal to center the sheet metal. As the movable rod 302 continues to move, one side of the movable rod 302 always presses and pushes the positioning plate 401 against one side of the sheet metal part, so that the pushed sheet metal part always remains centered, preventing excessive skew during the pushing of the sheet metal part, which would cause the area outside the painting range to not be effectively painted.

[0032] It should be added that one side of the lower end of the positioning plate 401 is curved, and the end of the movable rod 302 near the adjacent positioning plate 401 is inclined. The curved side of the lower end of the positioning plate 401 and the inclined end of the movable rod 302 make it easier for the movable rod 302 to push the positioning plate 401 closer to the sheet metal part.

[0033] It should be added that several guide rollers 4011 are equidistantly rotatably mounted on one side of the upper end of the positioning plate 401. By setting several guide rollers 4011, the contact area between the sheet metal part and the guide rollers 4011 is reduced when aligning the sheet metal part, thereby reducing the friction between the two and facilitating the pushing of the sheet metal part.

[0034] To accelerate the drying speed of the paint on the sheet metal parts, the drying assembly 5 includes: a roller conveyor line 501 located at one end of the machine base 1; and a drying box 502 located in the middle of the roller conveyor line 501.

[0035] During the process of the push plate 301 spraying the sheet metal parts onto the spray head 2, the painted parts are pushed further onto the roller conveyor line 501. When the sheet metal parts are on the roller conveyor line 501, the roller conveyor line 501 transports the painted sheet metal parts to the drying oven 502 for drying, thereby improving processing efficiency.

[0036] Working principle: When the power is turned on, the sheet metal part to be painted is placed on the machine base 1 during sheet metal painting. The electric push rod 303 is started. The output end of the electric push rod 303 retracts, driving the movable rod 302 to move towards the positioning plate 401. This causes the inclined surface of one end of the movable rod 302 to press against the arc surface of the lower end of the positioning plate 401, thereby pushing the positioning plate 401 closer to one side of the sheet metal to center it. As the movable rod 302 continues to move, one side of the movable rod 302 always presses and pushes the positioning plate 401 against one side of the sheet metal part, keeping the pushed sheet metal part always centered for painting. This prevents the sheet metal part from being skewed and affecting the painting quality. The painted part is then pushed onto the roller conveyor line 501. When the sheet metal part moves onto the roller conveyor line 501, the roller conveyor line 501 transports the painted sheet metal part to the drying chamber 502 for drying.
