Description

Technical Field

[0001] This utility model relates to the field of pencil production equipment technology, specifically to an intelligent plate selector. Background Technology

[0002] Pencils are the most commonly used writing tool for elementary school students, art students, and draftsmen. They mainly consist of three parts: the lead, the barrel, and the barrel coating. During pencil production, due to the varying quality of pencil slabs, they need to be screened and classified according to quality. Currently, this is generally done manually, with the slabs being inspected, sorted, and then stacked to prevent mixing of different types of slabs and affecting subsequent pencil production. However, manual inspection is time-consuming and labor-intensive, severely impacting work efficiency. Workers are prone to fatigue from prolonged screening, leading to errors and affecting the screening and subsequent processing results. Furthermore, the manual sorting and stacking of the slabs after inspection is also inefficient, as workers are fatigued from prolonged stacking and sorting, increasing the likelihood of errors and resulting in mixed slabs, thus affecting subsequent processing.

[0054] The working principle of this utility model is as follows: In use, the pencil board enters from the feeding device and enters the first detection tray groove of the first detection workbench. Driven by the first conveyor motor, the conveyor chain moves, and the push rods on the conveyor chain push the pencil board towards the detection components. Passing the thickness detection component and the side detection component, the thickness detection pressure roller moves upward, and the thickness detection sensor detects the displacement distance to detect the thickness of the pencil board. When passing the side detection component, the side detection sensor detects the side of the pencil board to check for missing edges or damage. Afterward, it enters the second detection tray groove of the second detection workbench. The pressure rollers on the pressure roller assembly limit the pencil board during conveying. To ensure that the pencil board does not shift during transport, the return spring is designed to accommodate pencil boards of various thicknesses. When passing through transparent glass, the upper and lower vision inspection components allow for comprehensive inspection of the pencil board from top to bottom using 2D and 3D cameras. A dust removal component is installed at the transparent glass to prevent dust from falling on the glass surface and affecting the camera's inspection effect. The combination of blowing and dust removal improves the dust removal effect and further ensures the inspection effect. Afterward, the pencil board is transported to subsequent processes. If jamming or maintenance is required, the support plate lifting cylinder will lift the support plate, and the corresponding pressure roller assembly and thickness inspection assembly will also rise. This makes it more convenient and faster to remove the jammed plate or perform inspection and maintenance on the corresponding position.

[0055] After inspection, the pencil boards enter the sizing device of the first sizing workbench. Based on the inspection results, they are classified: Category 1 pencil boards pass directly through the sizing device into the classification trough of the second sizing workbench; Category 2 pencil boards are pushed forward onto the first stacking platform by a sizing conveyor chain driven by a sizing conveyor motor; and Category 3 pencil boards are pushed backward onto the second stacking platform by a sizing conveyor motor. Both the first and second stacking platforms are equipped with toothed feeding platforms for easy loading of pencil boards. Several spring clips on the inner wall of the stacking platform support frame suppress fluctuations during pencil board stacking. A pressure plate assembly is located above the sizing device. The pressure plate of the pressure plate assembly is slidably connected to a pressure plate connecting rod on the pressure plate support frame via a cam clamping rod, allowing for height adjustment to accommodate pencils of different thicknesses. When the pencil boards on the second stacking platform reach a certain height, the forklift assembly's fork cylinder drives the fork handle to engage the pencil boards. At the bottom, the forklift lifting cylinder of the forklift lifting assembly lifts the forklift lifting platform, the forklift assembly on it, and the pencil board, raising them to be level with the third stacking platform. Then, the translation cylinder of the translation assembly moves the translation pusher to push the pencil board onto the third stacking platform. After that, the stacking platform moving cylinder of the third stacking platform moving assembly moves the third stacking platform forward, making it easy to remove the pencil board from the third stacking platform. Thus, the second and third category pencil boards are located at the front of the equipment. The first category of pencil boards on the sorting trough is directly stacked on the fourth stacking platform. The result of the fourth stacking platform is the same as that of the first stacking platform. This facilitates the sorting, stacking, and retrieval of pencil boards of various categories after inspection. If it is necessary to sort more than three quality categories of pencil boards, multiple sets of rejection devices can be added. The first category of pencil boards on the sorting trough of the first set enters the rejection device of the second set for re-sorting. The sorting principle is the same as that of the first set. At this time, the fourth stacking platform is located at the outlet of the last set of sorting troughs.
