[0002] Pencil is a kind of pen used for writing and drawing sketches. It has a history of more than 400 years. Among them, pencils for drawing sketches are divided into many types. It is divided into three stages of development, including graphite, wooden pen holder, and capped pencil; in addition, its colors include red and white, black and white, yellow and black stripes. The pencil holder is processed by using a slotting machine to plane the pencil plate to a specified thickness, and the slot plate has a core groove that is suitable for the diameter of the lead core, and then the lead core and the pencil plate are glued together with adhesive. After heating and drying in a clamped state, a white-holder pencil can be obtained.

[0003] When the glued lead and pencil board are clamped by a clamping device and placed in a drying device for drying, the hot air blown by the drying device is easily blocked by the clamping device and cannot directly act on the pencil, resulting in low drying efficiency of the glue on the pencil, affecting the production and processing efficiency of the pencil. Utility Model Content

[0024] The glued lead and pencil board are placed in layers by using a plurality of support plates 7 which are sleeved in sequence from top to bottom outside the drying tube 6. The plurality of support plates 7 are spaced apart from the plurality of springs 8, so that the plurality of springs 8 can separate the plurality of support plates 7. The plurality of support plates 7 are pushed by the pressing assembly to squeeze the plurality of springs 8, so that the spacing between adjacent support plates 7 is reduced, and the glued lead and pencil board can be clamped. The wind sent into the drying tube 6 by the blowing assembly is heated by the electric heating wire 10 and then led out along the air outlet 9, so that the clamped pencil can be dried. The height of the cover tube 4 can be adjusted by using the two first hydraulic cylinders 2, so that when the pencil is drying, the cover tube 4 can cover the outside of the drying tube 6 and cooperate with the base 1 to completely wrap all the pencils to be dried, so that the pencil drying effect is better.

[0025] An exhaust pipe 11 is fixedly passed through the top of the base 1 , a valve is provided on the exhaust pipe 11 , and the exhaust pipe 11 is located directly below the cover tube 4 .

[0026] The tail gas generated by drying the pencils can be discharged by opening the valve on the exhaust pipe 11. The gas outlet of the exhaust pipe 11 is connected to the tail gas purifier. The tail gas can be purified by the tail gas purifier before being discharged to avoid the tail gas polluting the environment.

[0027] Among them, the pressing assembly includes a fixed plate 12, which is fixedly installed on the top of the cover tube 4, and two second hydraulic cylinders 13 are arranged on the top of the fixed plate 12, and a push rod 14 is fixedly installed on the output end of the second hydraulic cylinder 13, and a through hole for the push rod 14 to slide is opened on the top of the cover tube 4.

[0028] The two second hydraulic cylinders 13 are used to push the two push rods 14 downward, and the two push rods 14 push the supporting plates 7, so that the multiple supporting plates 7 move downward in an orderly manner, and the pencils placed in layers are firmly clamped, so that the pencil gluing effect is better.

[0029] Among them, the blowing assembly includes a fan 15, which is arranged at the top of the cover tube 4, and an air supply pipe 16 is fixedly connected between the air outlet of the fan 15 and the cover tube 4. The junction of the air supply pipe 16 and the cover tube 4 is located directly above the drying tube 6, and the air inlet of the fan 15 is fixedly connected to the air induced draft pipe 17, and a filter 18 is arranged at the other end of the air induced draft pipe 17.

[0030] The air filtered by the filter 18 is sent into the drying tube 6 by the fan 15, and the air is heated by the electric heating wire 10, so that the pencil can be dried after the air is heated.

[0031] How this utility works:

[0032] At the beginning, the cover tube 4 is located above the drying tube 6, and the cover tube 4 does not wrap the drying tube 6. The glued lead cores and pencil boards are placed in order on multiple support plates 7. With the help of multiple support plates 7, they are placed in layers, so that the device can accommodate more pencils. After the pencils are placed, the two first hydraulic cylinders 2 are controlled to contract, so that the two first hydraulic cylinders 2 pull the cover tube 4 down until the drying tube 6 contacts the top of the inner side of the cover tube 4, and the cover tube 4 contacts the base 1, completing the wrapping of all the pencils to be dried, and connecting the exhaust pipe 11 to the exhaust gas purifier;

[0033] The two second hydraulic cylinders 13 are controlled to extend so that the two second hydraulic cylinders 13 push the two push rods 14 downward. After the push rods 14 contact the topmost support plate 7, they are continuously pushed downward until the multiple support plates 7 compress the multiple springs 8 and completely clamp the pencils placed in layers. The fan 15 is enabled to run. The fan 15 sends the air filtered by the filter 18 into the interior of the drying tube 6. The air is heated by the electric heating wire 10, so that the air is guided out along the air outlet 9 after being heated. The pencils can be dried until the pencils are dried. The exhaust gas discharged along the exhaust pipe 11 can be treated by the exhaust gas purifier before being discharged to avoid exhaust gas pollution.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
