Description

Technical Field

[0001] This utility model relates to the field of pencil lead testing technology, and in particular to a quality testing device for pencil leads. Background Technology

[0002] The main component of pencil lead is graphite. Actually, pencil lead is made by mixing graphite and clay in a certain proportion. "H" stands for "hard," representing the clay content and indicating the hardness of the pencil lead. The larger the number before "H" (e.g., 6H), the harder the pencil lead, meaning a greater proportion of clay mixed with graphite in the lead, resulting in less clear writing, often used for carbon copying. "B" stands for "black," representing the graphite content and indicating the softness of the pencil lead and the clarity of the writing. Ordinary pencils are generally marked "hb," while pencils used for filling in answer sheets during exams are usually marked "2b."

[0019] Reference Figure 1-5 This utility model provides a quality inspection device for pencil leads, including a workbench 1 and a mounting base 5. The mounting base 5 is fixedly connected to the upper part of the outer wall of the workbench 1, and a working groove 4 is formed on the outer wall of the workbench 1. It also includes: The detection plate clamping mechanism 3 is located on the top of the outer wall of the workbench 1, and includes a fixing component 31 and a clamping component 32. Lifting mechanism 6 is installed on the outer wall of mounting base 5 and is used to adjust the height; The fixing component 31 includes a mounting plate 311. There are two mounting plates 311, and both mounting plates 311 are fixedly connected to the top of the workbench 1. The outer wall of the mounting plate 311 is provided with a groove 312. A bidirectional threaded rod 313 is provided inside the groove 312. One end of the bidirectional threaded rod 313 is fixedly connected to one side of the groove 312 and rotatably connected. The other side is provided with a first motor 314 through the groove 312.

[0020] In an optional embodiment, the clamping assembly 32 includes a connecting rod 321, which is threadedly connected to both ends of a bidirectional threaded rod 313. A clamping plate 322 is fixedly connected to the outer wall of the connecting rod 321, and a clamping groove 323 is formed on the outer wall of the clamping plate 322.

[0021] Specifically, during use, the first motor 314, which is fixedly connected to the outer wall of the workbench 1, can be activated via the mounting plate 311 fixedly connected to the outer wall of the mounting plate 311. The output end of the first motor 314 is fixedly connected to a bidirectional threaded rod 313, which penetrates the outer wall of the mounting plate 311 and is located inside the groove 312. The connecting rod 321, which is threaded to the outer wall of the bidirectional threaded rod 313, drives the connecting rod 321. Since a clamping plate 322 is fixedly connected to the outer wall of the connecting rod 321, and a clamping groove 323 is provided on the outer wall of the clamping plate 322, the clamping plate 322 can be used to move horizontally through the clamping groove 323 on the outer wall of the clamping plate 322, thereby fixing or releasing the detection device plate.

[0022] In an optional embodiment, the lifting mechanism 6 includes a mounting groove 601, which is formed on the outer wall of the mounting base 5. A threaded rod 602 is provided on the inner wall of the mounting groove 601. A hinge plate 604 is threadedly connected to the outer wall of the threaded rod 602. A second motor 603 is provided at one end of the threaded rod 602.

[0023] Specifically, during use, the second motor 603 is turned on. The output end of the second motor 603 is fixedly connected to a threaded rod 602. The threaded rod 602 passes through the outer wall of the mounting base 5 and is set inside the mounting groove 601. The inner wall of the mounting groove 601 is rotatably connected to the threaded rod 602. The outer wall of the threaded rod 602 is threadedly connected to a hinge plate 604. Thus, the second motor 603 drives the threaded rod 602 to rotate, which in turn drives the detection fixing device body 7 through the hinge plate 604, thereby realizing the height adjustment of the detection fixing device body 7.

[0024] In an optional embodiment, a support base 2 is fixedly connected to the bottom of the outer wall of the workbench 1, a detection fixing device body 7 is movably connected to the outer wall of the hinge plate 604, an L-shaped support frame 9 is movably connected at the connection between the detection fixing device body 7 and the hinge plate 604, and an auxiliary detection plate 8 is installed on the inner wall of the L-shaped support frame 9.

[0025] In an optional embodiment, the first motor 314 is fixedly connected to the outer wall of the mounting plate 311, and the output end of the first motor 314 is connected to the bidirectional threaded rod 313 via a coupling.

[0026] In an optional embodiment, one end of the threaded rod 602 is rotatably connected to the inner wall of the mounting groove 601, and the other end passes through the mounting base 5 and is connected to the output end of the second motor 603 via a coupling. The second motor 603 is fixedly connected to the outer wall of the worktable 1.

[0027] Working principle: When in use, the pencil lead is installed on the detection fixing device body 7. Then, the second motor 603 is turned on. The output end of the second motor 603 is fixedly connected to the threaded rod 602. The threaded rod 602 passes through the outer wall of the mounting base 5 and is set inside the mounting groove 601. The inner wall of the mounting groove 601 is rotatably connected to the threaded rod 602. The outer wall of the threaded rod 602 is threadedly connected to the hinge plate 604. By manually adjusting the L-shaped support frame movably connected to the outer wall of the hinge plate 604, the pencil lead can be written on the auxiliary detection plate 8 to detect the writing smoothness of the pencil lead. Then, the auxiliary detection plate 8 is disassembled and the detection fixing device body 7 is lowered by the lifting mechanism 6. Then, the first motor 314 is fixedly connected to the outer wall of the workbench 1 via the mounting plate 311. The output end of the first motor 314 is fixedly connected to a bidirectional threaded rod 313. The bidirectional threaded rod 313 passes through the outer wall of the mounting plate 311 and is set inside the groove 312. Then, the connecting rod 321, which is threaded to the outer wall of the bidirectional threaded rod 313, drives the connecting rod 321. Since the outer wall of the connecting rod 321 is fixedly connected to a clamping plate 322, and the outer wall of the clamping plate 322 has a clamping groove 323, the horizontal movement of the detection device plate is achieved by using the clamping groove 323 on the outer wall of the clamping plate 322 to fix or release the detection device plate. By adjusting the height of the detection fixing device body, the pencil lead is pressed down to test the firmness of the pencil lead.
