Auxiliary device for pencil coating detection

Abstract

The invention discloses a pencil coating detection auxiliary device, and relates to the technical field of detection auxiliary equipment, the pencil coating detection auxiliary device comprises a protection shell, the protection shell is internally provided with a driving mechanism, a transmission mechanism, a blade group clamp, a pencil clamp, a rotating bearing 1 and a rotating bearing 2; the driving mechanism comprises a motor I and a motor II; the transmission mechanism comprises a positioning shaft, a screw rod and a slider, two ends of the positioning shaft are respectively fixed in the protective shell, the middle of the positioning shaft is slidably connected with the slider, the slider is in threaded connection with the screw rod, the left end of the screw rod is fixedly connected with a rotating shaft of a motor I, and the right end of the screw rod is fixedly connected with a rotating bearing I; a cutter mounting groove is formed in the front end of the blade group clamp, a cutter is arranged in the cutter mounting groove, and pencil clamps are arranged on two sides below the cutter; the end of the pencil clamp on the left side is fixedly connected with a rotating shaft of the second motor, and the end of the pencil clamp on the right side is fixedly connected with a second rotating bearing. And a sample container is arranged below the pencil clamp. The device is simple in structure, low in cost and capable of stripping the surface coating of the pencil efficiently and automatically.

Description

technical field [0001] The invention relates to the technical field of detection auxiliary equipment, in particular to a pencil coating detection auxiliary device. Background technique [0002] Pencil is the most commonly used writing tool for primary school students, art students, and draftsmen. It is mainly composed of three parts: pen core, pen holder and pen holder coating. Common shapes of pen barrels are: hexagon, triangle, and circle. In addition, pencils on the market are designed to cater to children's nature, with cartoon coating design, bright colors and gorgeous appearance. The coating of the pen barrel has two functions. On the one hand, it can protect the pen barrel, and on the other hand, it can beautify the appearance. However, the current coating basically adopts the spray paint mode. This kind of pigment may contain inorganic and organic substances. The organic substances are volatile, while the inorganic substances remain. On the pen holder, it is mainly ...

Problems solved by technology

In the actual inspection process, the preparation of the pencil barrel coating is more difficult

Standard requirements: The coating is obtained from the test sample by mechanical scraping. At present, all testing institutions use manual blade scraping. This method is time-consuming, laborious and inefficient, which is not conducive to the development needs of the modern testing industry.

There is no relevant equipment on the market that can be used for peeling off the coating of pencil barrels. In order to meet the needs of high-efficiency development, it is necessary to design a pre-processing auxiliary equipment that can be used to improve efficiency and liberate labor.
