DETAILED DESCRIPTION
[0019] Next, combine the Figure 1 -Attached Figure 5 A specific embodiment of the present invention is described in detail.
[0020] Reference Attachment Figure 1-Figure 5 A production cutting device for aluminum veneer includes a cutting machine body 1, on which an electrically controlled laser cutter 11 is slidably connected, and the laser cutter 11 moves to position and cut the aluminum veneer.
[0021] As mentioned in the background technology, due to the low hardness of aluminum veneer, especially pure aluminum or low-strength alloy materials, the aluminum veneer is not reinforced and is easily bent due to concentrated stress during transportation, resulting in reduced cutting accuracy. Based on this, the device is designed as follows: two symmetrically distributed dual-axis motors 12 are installed on the cutting machine body 1, and the dual-axis motor 12 is provided with a first screw 13. The first screw 13 is connected to a leveling component through a sliding part 14, aiming to use the leveling component to achieve reinforcement and correction of the aluminum veneer.
[0022] The leveling assembly includes a guide frame 15 slidingly connected to the sliding member 14, a movable frame 16 fixedly connected to the guide frame 15, two receiving plates 18 slidingly connected to the movable frame 16, and the aluminum veneer is supported by the two receiving plates 18, a positioning frame 161 fixedly connected to the movable frame 16, an electric push rod 110 is installed on the positioning frame 161, a lower pressure frame 111 is provided on the output shaft of the electric push rod 110, and an extrusion roller 112 is rotatably connected to the lower pressure frame 111, that is, the leveling effect of the aluminum veneer is achieved through the cooperation of the extrusion roller 112 and the two receiving plates 18.
[0023] The aluminum veneer is placed on the receiving plate 18, the electric push rod 110 is actuated, the lower pressing frame 111 is controlled to move downward, and the extrusion roller 112 is synchronously moved downward and contacts the aluminum veneer on the receiving plate 18, that is, the aluminum veneer is pressed between the extrusion roller 112 and the receiving plate 18, the double-axis motor 12 is started, the first screw 13 is controlled to rotate, the two sliding members 14 move forward, the guiding frame 15, the moving frame 16, the receiving plate 18, the positioning frame 161, the lower pressing frame 111 and the extrusion roller 112 move forward, that is, the extrusion roller 112 moves forward. 12 and the receiving plate 18 move toward the center of the aluminum veneer, and then, through the dual-axis motor 12, the first screw 13 is controlled to rotate in the opposite direction, and the two sliding members 14 move backward, and the guiding frame 15, the moving frame 16, the receiving plate 18, the positioning frame 161, the lower pressing frame 111 and the squeezing roller 112 move backward, which means that the squeezing roller 112 and the receiving plate 18 gradually move to the edge of the aluminum veneer. Based on the squeezing action of the squeezing roller 112 and the receiving plate 18, the aluminum veneer is fixed and straightened, and the bent part is straightened.
[0024] Subsequently, the laser cutter 11 is activated, moves to the target area, and cuts the leveled aluminum veneer.
[0025] During the above-mentioned leveling action, the receiving plate 18 is slidably connected to the movable frame 16. The purpose is to adjust the spacing between the two receiving plates 18 by sliding the receiving plate 18 to adapt to aluminum veneers of different sizes. However, during the actual cutting process, the two receiving plates 18 should remain fixed relative to the movable frame 16 to avoid accidental sliding of the receiving plate 18 and affecting the cutting accuracy of the aluminum veneer. Therefore, one end of the receiving plate 18 is connected to the movable frame 16 by a bolt 19. The bolt 19 is tightened, and the receiving plate 18 can slide freely on the movable frame 16. The spacing is adjusted according to the size of the aluminum veneer. The bolt 19 is tightened, and the receiving plate 18 is fixed to the movable frame 16, thereby preventing the subsequent sliding of the receiving plate 18.
[0026] Based on the fact that the squeezing roller 112 is rotatably connected to the lower pressing frame 111, in order to ensure that the squeezing roller 112 cooperates with the receiving plate 18 during the backward movement of the lower pressing frame 111 to achieve the clamping and leveling of the aluminum single plate, the squeezing roller 112 cannot rotate when it moves backward. Specifically: both ends of the squeezing roller 112 are fixedly connected to the ratchet 113, the lower pressing frame 111 is fixedly connected to the support rod 116, and the support rod 116 is rotatably connected to the ratchet 114, the ratchet 113 and the ratchet 114 cooperate, and the ratchet 113 and the ratchet 114 cooperate. A first torsion spring 115 is provided between the support rod 116 and the support rod 116, and the squeezing roller 112, the ratchet 113 and the pawl 114 form a one-way gear structure, that is, when the squeezing roller 112 moves forward, the ratchet 113 engages the pawl 114, and the squeezing roller 112 rotates freely; when the squeezing roller 112 moves backward, the pawl 114 restricts the ratchet 113, thereby restricting the squeezing roller 112 from rotating freely. In this way, when the lower pressing frame 111 moves backward, the squeezing roller 112 remains in a non-rotating state, and cooperates with the receiving plate 18 to level the aluminum veneer.
[0027] As mentioned above, the two sliding members 14 move toward the center of the aluminum veneer (i.e., move forward), and the guiding frame 15, the movable frame 16, the receiving plate 18, the positioning frame 161, the lower pressing frame 111 and the squeezing roller 112 move forward, and the aluminum veneer is pressed between the squeezing roller 112 and the receiving plate 18. The squeezing roller 112 moves forward and rotates, the pawl 114 cooperates with the ratchet 113, the ratchet 113 rotates synchronously, and the first torsion spring 115 is deformed.
[0028] Through the dual-axis motor 12, the two sliding members 14 move toward the edge of the aluminum veneer (i.e., move backward), and the guiding frame 15, the movable frame 16, the receiving plate 18, the positioning frame 161, the lower pressure frame 111 and the squeezing roller 112 move backward. Because the pawl 114 restricts the ratchet 113, the squeezing roller 112 moves backward without rotating. The squeezing roller 112 and the receiving plate 18 gradually move to the edge of the aluminum veneer, and then the aluminum veneer is straightened and leveled, and then the laser cutter 11 is started for cutting.
[0029] The cut aluminum veneers are usually stored and transported in a flat state. In order to reduce the friction scratches of the aluminum veneers during handling and stacking and reduce the storage and transportation costs, this device uses a winding component to roll the cut aluminum veneers for storage.
[0030] The winding assembly includes a bracket 27 fixed to the rear side of the mobile frame 16, and a servo motor 2 is provided on the bracket 27. A slide rail 17 is provided on the rear side of the mobile frame 16. Two symmetrically distributed support frames 26 are slidably connected to the slide rail 17. A winding member 25 is rotatably connected between the two symmetrically distributed support frames 26. A winding groove is provided on the winding member 25, and the aluminum veneer is intended to extend into the winding groove. The winding effect is achieved by the rotation of the winding member 25. The output shaft of the servo motor 2 is connected to the winding member 25, and the servo motor 2 is the rotation power source of the winding member 25.
[0031] In order to facilitate the directional extension of the aluminum single plate on the receiving plate 18 into the winding groove on the winding member 25, a guide plate 23 is rotatably connected to the receiving plate 18, and a second torsion spring 24 is cooperated between the guide plate 23 and the receiving plate 18. The end of the guide plate 23 is connected to the winding groove on the winding member 25. The purpose is that the aluminum single plate on the receiving plate 18 is guided by the guide plate 23 to move to the winding groove on the winding member 25.
[0032] The edges of the cut aluminum veneer are still pressed by the receiving plate 18 and the squeezing roller 112. In order to facilitate the aluminum veneer to be guided by the receiving plate 18 and the guide plate 23 and move to the winding groove on the winding member 25, the following linkage design is made: a conduction rod 22 is fixed to the ratchet 113, and a belt 21 is matched between the conduction rod 22 and the output shaft of the servo motor 2. Based on the existence of the belt 21, the power of the servo motor 2 is transmitted to the conduction rod 22, driving the ratchet 113 and the squeezing roller 112 to rotate, and the rotation of the squeezing roller 112 provides a thrust to the aluminum veneer pressed thereunder.
[0033] After the laser cutter 11 cuts, the servo motor 2 starts to operate, and through the transmission of the belt 21, the ratchet 113 and the squeezing roller 112 rotate. The rotation of the squeezing roller 112 pushes the aluminum veneer upward, and the aluminum veneer moves to the winding groove on the winding member 25 under the guidance of the guide plate 23. As the servo motor 2 operates, the winding member 25 rotates, and the aluminum veneer is wound on the winding member 25.
[0034] The thickness of the aluminum veneer rolled on the winding member 25 increases, and it is squeezed with the guide plate 23. As the winding member 25 continues to rotate, the guide plate 23 rotates downward under pressure, and the second torsion spring 24 is deformed. After the winding is completed, the winding member 25 is removed, the second torsion spring 24 is reset, and the guide plate 23 is reset accordingly, which is convenient for the next round of use.
[0035] In order to facilitate the stacking and storage of the wound aluminum veneer, the present device moves the winding piece 25 out of the cutting machine body 1 through a transfer assembly. A fixing frame 3 is fixedly connected to the two side walls of the cutting machine body 1. The fixing frame 3 is rotatably connected to the second screw 31. The second screw 31 is fixedly connected to the first gear 32. The output shaft of the servo motor 2 is fixedly connected to the second gear 33. The first gear 32 is engaged with the second gear 33. The second screw 31 is threadedly connected to a positioning frame 34. The positioning frame 34 and the winding piece 25 can be snapped together. The winding piece 25 can be moved out by means of the movement of the positioning frame 34.
[0036] The aluminum veneer is wound on the winding member 25, and the dual-axis motor 12 is started to drive the movable frame 16. The winding member 25 and the support frame 26 move toward the direction close to the transfer assembly until the positioning frame 34 clamps and receives the winding member 25. The dual-axis motor 12 is turned off, and the servo motor 2 is started. The second gear 33 rotates and engages the first gear 32. The first gear 32 rotates, and the second screw 31 rotates under control. The positioning frame 34 moves to the left on the second screw 31. Based on the clamping of the positioning frame 34 to receive the winding member 25, the winding member 25 is linked to move to the left, and the support frame 26 moves to the left on the slide rail 17 until the support frame 26 disengages from the slide rail 17, that is, the winding member 25 disengages from the cutting machine body 1, thereby allowing the aluminum veneer on the winding member 25 to be removed and stored.
[0037] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
