Description

Technical Field

[0001] This utility model belongs to the field of pencil processing technology, and in particular relates to a pencil two-color impregnation and drying device. Background Technology

[0002] Paper pencils are pencils made primarily of paper. The paper is typically processed using special techniques, such as rolling and gluing, to form the shape of the pencil barrel, and then the pencil lead is inserted into it. Compared to traditional wooden pencils, paper pencils are relatively lighter and more environmentally friendly, reducing the use of wood and helping to protect forest resources.

[0003] Two-color pencil dipping involves coating the pencil barrel with two different colors to easily distinguish the ends of the pencils. Paper pencils are generally bonded with environmentally friendly glue. To ensure the stability of the dipping and the coloring effect, the glue needs to be dried to improve the adhesion strength of the paint. Therefore, a pencil two-color dipping drying device is needed, which uses a roller-type tumbling drying method. This method improves the uniformity of the drying heat applied to the pencil barrel surface and prevents the glue from sticking together during the drying process by causing the pencil barrel to tumble under gravity. Utility Model Content

[0023] In the following description, embodiments of the pencil two-color dipping and drying apparatus of the present invention will be described with reference to the accompanying drawings.

[0024] Figure 1-5This invention illustrates a pencil two-color dipping and drying device according to an embodiment of the present invention, comprising a drying cylinder 1: a rotating column 2 is rotatably connected to the inner cavity of the drying cylinder 1, and multiple rotating disks 3 are fixedly connected to the surface of the rotating column 2. Multiple guide rails 11, fixedly connected to the rotating disks 3, are circumferentially distributed on the surface of the rotating column 2. Multiple pulleys 12 are rotatably connected to the opposite side of each pair of adjacent guide rails 11. An arc-shaped groove 13 is formed on the surface of a second perforated semicircular tube 5 away from the first perforated semicircular tube 4. The pulleys 12 roll in contact with the inner cavity of the arc-shaped groove 13. The device utilizes the guide rails 11, pulleys 12, and... With the cooperation of the arc-shaped slide groove 13, the second perforated semicircular tube 5 plays a limiting and guiding role, thereby improving the stability of the second perforated semicircular tube 5 during the sliding process. Multiple first perforated semicircular tubes 4 are annularly distributed on the surface of the rotating column 2. The first perforated semicircular tubes 4 are fixed to the rotating disk 3. Threaded plates 14 are welded to the right ends of both the first and second perforated semicircular tubes 4 and 5. Threaded knobs 15 are threadedly connected to the surfaces of the two threaded plates 14, and the two threaded plates 14 are fixedly connected by the threaded knobs 15. A second perforated semicircular tube 5 is slidably connected to one side of the first perforated semicircular tube 4. The inner cavity of the second perforated semicircular tube 5 is fixedly connected to multiple partitions 6. A side plate 7 is fixedly connected to the right side of the drying cylinder 1. A loading / unloading assembly 9 is provided on the right side of the side plate 7. The loading / unloading assembly 9 includes a material outlet 91 opened at the top right side of the side plate 7. A sealing plate 92 is rotatably connected to the right side of the side plate 7. A threaded pin 93 is fixedly connected to the top right side of the side plate 7. An arc-shaped groove 94 is opened on the right side of the sealing plate 92, and the arc-shaped groove 94 is fitted onto the surface of the threaded pin 93. A threaded sleeve 95 is threadedly connected to the surface of the threaded pin 93, and the threaded sleeve 95 is pressed against the sealing plate 92. On the surface, the sealing plate 92 is limited and fixed by the cooperation of the threaded pin 93, the arc-shaped groove 94 and the threaded sleeve 95, so that the sealing plate 92 can be tightly pressed into the inner cavity of the feed port 91, thereby sealing the feed port 91 and preventing the heat in the inner cavity of the drying cylinder 1 from dissipating to the outside. A servo motor 8 is provided on the left side of the drying cylinder 1. The output shaft of the servo motor 8 is fixedly connected to the drive gear 16. The left end of the rotating column 2 extends to the outside of the drying cylinder 1 and is fixedly connected to the force-receiving gear 10. The force-receiving gear 10 meshes with the drive gear 16.

[0025] Working Principle: In use, the user rotates the threaded sleeve 95 to disengage it from the surface of the threaded pin 93. Then, the user rotates the sealing plate 92 to disengage the arc-shaped groove 94 from the surface of the threaded pin 93. Next, the user rotates the threaded knob 15 to disengage the two threaded plates 14, pulling the second perforated semi-circular tube 5 to the right. The second perforated semi-circular tube 5 slides out to the right from the inner cavity of the feed port 91. Simultaneously, the pulley 12 rolls within the inner cavity of the arc-shaped groove 13, supporting and limiting the second perforated semi-circular tube 5. Then, the user places the two-color pen refills into the inner cavity of the second perforated semi-circular tube 5 and separates them using the partition 6. The user then pushes the second perforated semi-circular tube 5 back into the inner cavity of the drying cylinder 1 and fixes the threaded plate 14 using the threaded knob 15. Finally, the user turns on the servo motor 8, causing it to slowly rotate a certain distance, driving the gears... Under the meshing transmission action of disk 16 and force-receiving gear disk 10, the rotating column 2 drives the first perforated semi-circular tube 4 and the second perforated semi-circular tube 5 to rotate through the rotating disk 3, so that the other first perforated semi-circular tubes 4 and second perforated semi-circular tubes 5 are positioned on the same horizontal line as the feed port 91 to discharge the two-color pen refills. Finally, the sealing plate 92 is closed, and the threaded sleeve 95 is rotated to the surface of the threaded pin 93 to fix the sealing plate 92 and close the feed port 91. Finally, the servo motor 8 is turned on. The servo motor 8 drives the rotating column 2 to rotate in the inner cavity of the drying cylinder 1 through the cooperation of the force-receiving gear disk 10 and the drive gear disk 16, and causes the two-color pen refills to rotate in the inner cavity of the first perforated semi-circular tubes 4 and the second perforated semi-circular tubes 5. The heat generated by the drying cylinder 1 passes through the holes on the surface of the first perforated semi-circular tubes 4 and the second perforated semi-circular tubes 5 and acts on the surface of the two-color pen refills to dry them.

[0026] In summary, this pencil two-color dipping and drying device, through the coordinated use of the first perforated semi-circular tube 4, the second perforated semi-circular tube 5, and the loading and unloading assembly 9, enables the rapid assembly and stacking of two-color pencil leads. Subsequently, under the coordinated driving action of the servo motor 8, the force-bearing gear disc 10, and the drive gear disc 16, and the coordinated use of the drying cylinder 1, the rotating column 2, and the rotating disk 3, the two-color pencil leads are rotated and dried, thus achieving the purpose of easy loading and unloading of two-color pencil leads and uniform heating and drying.
