Description

Technical Field

[0001] The present invention relates to the technical field of pencil production, specifically to a four-sticking machine for producing environment-friendly pencils. Background Art

[0002] A pencil is a special pen for writing and drawing sketches, mainly composed of a pencil rod, a lead core, and a pencil aluminum ferrule. The production process of pencils includes the following steps: 1. Pencil board processing; 2. Lead core processing; 3. Rod processing; 4. Appearance decoration processing.

[0003] During the processing of pencils, it is also necessary to paint the surface of the pencils. After painting, a drying device is required to dry them. When the traditional drying device dries the pencils, it generally uses a temperature control device to control the temperature of the drying channel. That is, when the temperature rises to the set temperature, the heating device stops heating. When the heating stops, the temperature in the pipeline will drop a little. When reheating to the set temperature again, it takes a certain amount of time. During this period, the temperature in the drying channel fluctuates, thus affecting the drying effect of the pencils.

[0030] Working principle:

[0031] The pencil and the pen inserting tray are respectively placed on the inserting and flattening integrated machine 5 for pen inserting. The pen inserting tray filled with pencils is conveyed to the UV dipping device 8 by the transmission mechanism 29. After the pen inserting tray is dipped with UV, it rotates to make the pen tip face upward and slowly passes through the UV lamp channel 6. When the pen inserting tray reaches the two-dipping landing device 9, the UV paint on the pen has been completely solidified. After the pen inserting tray is dipped with paint, it is pushed into the corresponding drying channel 12. After two hours of conveying and drying, it enters the selective dipping rewinding pen discharging conveying device 7, and reaches the three-dipping landing device 10 through the rewinding mechanism for dipping with paint. After the pen inserting tray is dipped with paint, it is pushed into the corresponding drying channel 12. After two hours of conveying and drying, it enters the selective dipping rewinding pen discharging conveying device 7, and reaches the four-dipping landing device 11 through the rewinding mechanism for dipping with paint. After the pen inserting tray is dipped with paint, it is pushed into the corresponding drying channel 12. After two hours of conveying and drying, it enters the selective dipping rewinding pen discharging conveying device 7. The pen inserting tray enters the pen discharging device 3 for automatic pen discharging. The pen inserting tray after pen discharging can be selected to be put into the inserting and flattening integrated machine 5 again through the automatic rewinding device 4 for repeated use, or it can also be selected to be pushed out through the manual rewinding device 2.

[0032] When the pencil enters the drying channel 12, the first fan 16 and the first heating tube 19 are started. The first fan 16 introduces air into the interior of the first heating cylinder 18 for heating. Then, the hot air enters the fourth pipe 22 through the third pipe 21, so that the hot air enters the interior of the drying channel 12 and is evenly discharged through a number of through holes 15. When the temperature sensor detects a slight fluctuation in the temperature inside the drying channel 12, if the temperature sensor detects a temperature drop, the second fan 23 is started. The second fan 23 introduces air into the second heating cylinder 25 and heats it through the second heating tube 26, so that the hot air enters the sixth pipe 27 and then mixes with the gas in the third pipe 21 to increase the gas temperature. If the temperature sensor detects a temperature rise, the second fan 23 is started. The second fan 23 introduces air into the seventh pipe 28 and then mixes with the gas in the third pipe 21 to lower the gas temperature.
