Description

Technical Field

[0001] The invention relates to the technical field of veneer paper processing, in particular to an automatic feeding device for veneer paper coating processing. Background Art

[0002] Veneer is a veneer decoration used in furniture and wall products. It is a thin wood veneer or veneer material with the characteristics of precious tree species. Natural veneer will have naturally formed mineral scars and uneven textures, and needs to be modified by artificial color coating to reach a uniform standard. The original natural wood is processed and dyed without losing the characteristics of the natural wood itself (light color difference and natural texture). The dyed veneer after treatment has a smooth surface and rich colors; it can complete the transformation of the defects of the original wood.

[0003] Generally, veneer paper is coated with paint using a coating machine. Usually, the veneer paper is manually placed on a conveyor belt, and the conveyor belt is used to load the veneer paper, so that the veneer paper enters the coating machine for coating and coloring. The above-mentioned veneer paper loading method also has the following shortcomings: 1. Since the veneer paper is relatively thin, when the veneer paper is manually placed on the conveyor belt, due to improper manual picking and placement, the veneer paper is prone to wrinkles. Once the wrinkled veneer paper enters the coating machine for coloring, it will cause uneven coloring on the surface of the veneer paper, affecting the quality of the veneer paper processing; 2. When the veneer paper is manually placed on the conveyor belt, due to differences in each manual operation, the veneer paper cannot be loaded at a constant frequency, and as the processing time increases, the efficiency of manual placement of the veneer paper will gradually decrease, affecting the efficiency of the veneer paper coating process.

The pressing belt 73 is used to press the edge of the veneer paper to prevent the veneer paper from deviating and wrinkling during the color coating process. The rotating shaft 1 21 at the right end drives the rotating shaft 2 72 at the right end to rotate through the gear set, and then the rotating shaft 2 72 drives the pressing belt 73 to rotate, so that the pressing belt 73 can press the edge of the veneer paper and convey the veneer paper to the right together with the conveyor belt 23.

[0056] See also Figure 1-Figure 13 When used specifically, step one, the second toggle plate 62 is driven to rotate by the driving motor three 61, and then the second toggle plate 62 drives the second groove wheel 64 and the first belt pulley 65 to rotate, and then the first belt pulley 65 drives the left rotating shaft 21 and the conveying roller 22 to rotate through the belt, and then the conveying roller 22 drives the conveyor belt 23 to rotate clockwise, so that the conveyor belt 23 performs a conveying without placing the veneer paper.

[0057] Step 2: The left rotating shaft 21 drives the transmission rod 332 to rotate through the first worm gear, and then the transmission rod 332 drives the rotating disk 333 to rotate, so that the rotating disk 333 drives the push rod 334 to move a circle, and the push rod 334 first pushes the groove frame 337 and the first rack 336 to slide backward, and the first rack 336 drives the first gear 338 to rotate clockwise, and the first gear 338 drives the shaft rod 322 and the swing rod 323 to rotate clockwise, so that the swing rod 323 drives the electric suction cup 31 to move off the conveyor belt 23 moves to the feeding mechanism 4 on the rear side, then the electric suction cup 31 absorbs a piece of veneer paper, and then the push rod 334 pushes the slot frame 337 and the first rack 336 to slide forward, and the first rack 336 is used to drive the first gear 338 to rotate counterclockwise, and the first gear 338 drives the shaft 322 and the rocker arm 323 to rotate counterclockwise, so that the rocker arm 323 drives the electric suction cup 31 from the feeding mechanism 4 on the rear side to the conveyor belt 23, so that the electric suction cup 31 transfers the absorbed veneer paper to the conveyor belt 23.

[0058] Step three, when the electric suction cup 31 moves from the rear feeding mechanism 4 to the conveyor belt 23, the first toggle plate 458 is driven to rotate by the driving motor 2 457, and then the first toggle plate 458 drives the first groove wheel 456 to rotate intermittently, and then the first groove wheel 456 drives the connecting rod 454 and the second gear 455 to rotate intermittently, so that the second gear 455 pushes the movable rod 452 and the lifting plate 46 upward to a height of the thickness of the veneer paper, so that the veneer paper on the top is maintained at the same height, which is convenient for the electric suction cup 31 to absorb the veneer paper at the same position.

[0059] Step 4, then repeat step 1, so that the conveyor belt 23 conveys the veneer paper to the bottom of the housing 53, and then the third groove wheel 66 and the second pulley 67 are driven by the driving motor 3 61 to rotate, and then the second pulley 67 drives the transmission rod 3 588 to rotate through the belt, and the transmission rod 3 588 drives the inner gear ring 587 to rotate through the second worm gear, and the inner gear ring 587 first drives the first forward gear 581 to rotate, and then the first forward gear 581 drives the movable section 522 to rotate through the belt, so that the lead screw 523 moves downward along the fixed section 521, driving The shell 53 moves downward, placing the spreading plate 1 54 and the spreading plate 2 56 on the surface of the veneer paper, and then the inner gear ring 587 drives the second forward gear 584 to rotate, and the second forward gear 584 drives the transmission rod 2 551 to rotate, and the transmission rod 2 551 drives the center gear 552 to rotate, so that the center gear 552 pushes the second rack 553 to move away from the center of the shell 53, and then the second rack 553 drives the spreading plate 1 54 to move away from the center of the shell 53, so that the spreading plate 1 54 flattens the front and back sides of the veneer paper.

[0060] Step 5, then the inner gear ring 587 drives the first reverse gear 582 to rotate, and the first reverse gear 582 drives the first forward gear 581 to rotate in the opposite direction after being driven by the two first transmission gears 583, so that the first forward gear 581 drives the movable section 522 to rotate in the opposite direction, so that the lead screw 523 drives the shell 53 to move upward, and the expansion plate 1 54 and the expansion plate 2 56 are moved upward and separated from the veneer paper, and then the inner gear ring 587 drives the second reverse gear 585 to rotate, and the second reverse gear 585 drives the second forward gear 584 to rotate in the opposite direction after being driven by the two second transmission gears 586, thereby driving the transmission rod 2 551 and the center gear 552 to rotate in the opposite direction, and then the center gear 552 drives the second rack 553 to move toward the center of the shell 53, so that the expansion plate 1 54 moves toward the center of the shell 53 and resets, and in the process of the movement of the expansion plate 1 54, the third rack 572 drives the third gear 571 to rotate in the opposite direction, and then the third gear 571 drives the expansion plate 2 56 to rotate toward the center of the shell 53 and resets.

[0061] Step six, the conveyor belt 23 then conveys the flattened veneer paper to the right to the bottom of the pressing belt 73, and uses the pressing belt 73 to press the front and rear edges of the veneer paper to prevent the veneer paper from wrinkling during the coating process. While the conveyor belt 23 moves, the rotating shaft 1 21 at the right end can drive the rotating shaft 2 72 at the right end to rotate through the gear set, and then the rotating shaft 2 72 drives the pressing belt 73 to rotate counterclockwise, so that the pressing belt 73 and the conveyor belt 23 convey the veneer paper to the right together, and the veneer paper is coated with color when passing through the coating mechanism 8, and finally the colored veneer paper is sent out from the right end of the conveyor belt 23.
