Description

Technical Field

[0001] This invention belongs to the field of metal panel technology, and specifically relates to a precision straightening device for metal panels. Background Technology

[0002] Common metal decorative panels are made by hot-pressing various colored aluminum foils onto the surface of MDF sheets, creating single-sided and double-sided panels with various patterns and styles. These include brushed finishes, painted effects, and more. Because aluminum foil itself is metal, it possesses a bright metallic texture. Combined with patterned treatments, this allows for greater diversity in metal panel designs, meeting the needs of various furniture pieces, integrated metal cabinets, interior backgrounds, and more, resulting in a more sophisticated and elegant look. Unlike melamine boards, it also has fire-retardant and waterproof properties, making it an ideal material for decoration. It is especially suitable for large public spaces. This product is manufactured by a limited company. Metal decorative panels are environmentally friendly and elegant, making them an ideal choice for home décor.

[0003] When the metal is ultra-thin and low in the middle with upturned ends, the current market practices for handling such metal panels require manual operation. The metal panel is held by the tail end, which is then moved upwards to align the upturned front end with the machine body. The metal panel is then pushed into the straightening machine for correction, and the tail end is released. Simultaneously, the corrected metal panel is removed from the exit of the straightening machine by manual operation. This manual operation is time-consuming, labor-intensive, and reduces processing efficiency. Summary of the Invention

[0035] like Figure 1 - Figure 10 As shown, a precision straightening device for metal panels according to the present invention includes a straightening body 1. A first plate 2 and a second plate 3 are respectively fixed on the two side walls of the straightening body 1. A straightening groove 4 is provided inside the straightening body 1 to connect the first plate 2 and the second plate 3 for the passage of the metal panel. A third plate 5 is fixed on one side wall of the straightening mechanism directly above the first plate 2. A first orientation adjustment component 6 and a second orientation adjustment component 7 are fixed on the bottom of the third plate 5 from left to right. A first positioning component 8 for positioning the front end of the metal panel is slidably provided on the first orientation adjustment component 6. A second positioning component 9 for positioning the rear end of the metal panel and a third positioning component 10 for positioning irregular and irregularly shaped metal panels are slidably provided on the second orientation adjustment component 7. A limiting mechanism 11 for limiting the position of the metal panel is fixed on the first plate 2. A cleaning mechanism 12 for removing particles on the metal panel is fixed on the first plate 2 near the entrance of the straightening groove 4.

[0036] The limiting mechanism 11 includes a second motor 111, a first limiting plate 112, a third motor 113, and a second limiting plate 114.

Two first limiting plates 112 are symmetrically slidably mounted on the first plate 2. The first limiting plates 112 are threaded onto the lead screw slides. The third motor 113 is fixedly mounted on the first limiting plate 112. A lead screw slide is rotatably mounted inside the first limiting plate 112 via bearings.

Specifically, when the metal is ultra-thin and has a low center and upturned ends, existing market solutions for this type of... When operating on metal panels, manual operation is required. The tail end of the metal panel is held and moved upwards to align the upturned front end with the first plate 2. The metal panel is then pushed into the straightening machine for straightening, and the tail end is released. Simultaneously, the straightened metal panel is manually removed from the outlet of the straightening machine 1.

Secondly, when the metal is ultra-thin and low in the middle with upturned ends, the metal panel is placed on top of the first plate 2, and the limiting mechanism 11 limits its position. It should be noted that... The limiting mechanism 11 does not require the metal panel to be abutted and fastened. It can limit the metal panel within the length of the straightening groove 4. The second motor 111 can be started to drive the lead screw slide to rotate, thereby driving the two first limiting plates 112 to move in opposite directions to adjust the limiting space. At the same time, according to the width of the metal panel, the third motor 113 can be started to drive the two second limiting plates 114 to move, thereby expanding the limiting width. At the same time, the fan can be started to blow air on the metal panel to remove particles on the surface of the metal panel and avoid damage to the surface of the metal panel during the extrusion process.

The two ends of the third roller 93 are rotatably mounted between the two side walls of the third C-shaped plate 92 via bearings. There are two second electric push rods 94, which are symmetrically mounted on the two side walls of the third C-shaped plate 92. The fourth C-shaped plate 95 is fixedly mounted on the output end of the second electric push rod 94. The two ends of the fourth roller 96 are rotatably mounted between the two side walls of the fourth C-shaped plate 95 via bearings.

[0041] Preferably, the third positioning component 10 includes a third multi-stage electric push rod 101, a fifth C-shaped plate 102, a rotating shaft 103, a first motor 104, a connecting plate 105, a third electric push rod 106, a clamping plate 107, a support block 108, a rotating rod 109, and a pressing roller 1010.

After the limiting is completed, the position of the clamping plate 107 is adjusted according to the upward tilt of the metal panel tail. The position of the third multi-stage electric push rod 101 is adjusted by adjusting the third electric slide rail 71 and the fourth electric slide rail 73. After adjustment, The third multi-stage electric push rod 101 is activated to lower the panel. After it reaches the top of the metal panel, the first motor 104 is activated to rotate the rotating shaft 103, thereby driving the connecting plate 105 on the rotating shaft 103 to rotate. The connecting plate 105 is rotated to the same angle as the upturned tail of the metal panel and then stops. After stopping, the third multi-stage electric push rod 101 and multiple electric slide rails drive the two pressing rollers 1010 to be positioned on both sides of the metal panel. The third electric push rod 106 is activated to clamp the upturned tail end with the pressing rollers 1010. After clamping, the third multi-stage electric push rod 101 is activated to raise the metal panel. After rising, the front end of the panel is aligned with the first plate 2. Then, the first multi-stage electric push rod 81 is activated to drive the first roller 83 to descend and abut against the front end. At the same time, it can be determined whether the first electric push rod 84 needs to be activated to drive the second roller 86 to move, thereby expanding the positioning distance of the first positioning component 8, based on the shape of the panel. Then, the metal panel is sent to the straightening machine body 1 by the electric slide rail and the fixing of the panel is released. When the metal panel is arched, there is no need to use the third positioning component 10. The metal panel can be limited by pressing down the first positioning component 8 and the second positioning component 9.

When the metal panel enters the straightening machine body 1, in order to avoid excess particles on the metal panel affecting the surface of the panel, a cleaning mechanism 12 is set at the entrance of the straightening groove 4 to clean the surface. First, the front end of the panel is placed between the first wiping plate 125 and the second wiping plate 128. The fourth electric push rod 121 is activated to clamp the panel between the two wiping plates. When the fourth electric push rod 121 is pressed down, it pushes the push rod to slide inside the measuring cylinder 123, so that the cleaning agent inside the measuring cylinder 123 enters the first tube 124. The dosage enters the second tube 126 through the telescopic tube 127. The liquid inside the first tube 124 and the second tube 126 is squeezed into the wiping cotton, thereby scraping and cleaning the metal panel from top to bottom, ensuring the integrity of the panel and reducing production costs.
