Description

Technical Field

[0001] This utility model relates to the field of watercolor pen refill testing, specifically a device for detecting ink dispensing from watercolor pen refills used in watercolor pen manufacturing. Background Technology

[0002] Watercolor pens are a type of painting tool widely used in painting creation and daily doodling. They are colored writing and painting tools, usually consisting of a pen barrel, a nib, and colored ink or pigment stored inside. The pen barrel is mostly made of plastic, which is lightweight and easy to hold. Its shape is ergonomically designed, making it convenient for long-term use without causing fatigue.

[0003] In existing technology, the amount of ink dispensed by a watercolor pen directly affects the painting effect. Uneven ink dispensing can cause mottled marks on the picture and affect the quality of the work. Therefore, after the watercolor pens are processed, the ink dispensing of the pen refills is tested to ensure that each watercolor pen can achieve good performance. However, due to the limitations of the testing conditions, when the ink dispensing of the pen refills after the watercolor pen processing and production is tested, most inspection devices can only test the pen refills one by one, and manual sorting is required, which is inefficient. Utility Model Content

[0004] To address the shortcomings of existing technologies, which are limited by testing conditions, most inspection devices can only test each pen refill individually during ink dispensing testing after watercolor pen processing, requiring manual sorting and resulting in low work efficiency, this utility model proposes an ink dispensing testing device for watercolor pen refills.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a pen core ink dispensing detection device for watercolor pen processing, including a base plate, a detection mechanism provided on one side of the base plate, and a fixing mechanism fixedly connected to one side of the base plate.

[0006] The detection mechanism includes a fixed plate located on one side of a base plate. A first gear and a second gear are rotatably connected to one side of the fixed plate, with the teeth of the first gear meshing with the teeth of the second gear. A third gear is fixedly connected to one side of the first gear, and a fourth gear is rotatably connected to one side of the second gear, with the teeth of the fourth gear meshing with the teeth of the third gear. A cylinder is fixedly connected to one side of the fourth gear, and a limiting plate is fixedly connected to the surface of the cylinder. A connecting rod is rotatably connected to the inner cavity of the cylinder via a bearing. One side of the connecting rod extends through to one side of the fourth gear, and one side of the connecting rod is fixedly connected to one side of the second gear. A hollow block is fixedly connected to one side of the connecting rod, and a slider is slidably connected to the inner cavity of the hollow block. A round rod is slidably connected to the inner cavity of the limiting plate, and one side of the round rod is fixedly connected to one side of the slider.

[0007] Preferably, the fixing mechanism includes a fixing rod, one side of which is fixedly connected to one side of the base plate, a movable block is slidably connected to the surface of the fixing rod, a hollow groove is formed on the surface of the fixing rod, a plurality of hollow grooves are provided, bolts are threadedly connected to the hollow grooves and the inner cavity of the movable block, and a detection plate is fixedly connected to one side of the movable block.

[0008] Preferably, a placement cylinder is provided on one side of the slider, and two placement cylinders are provided, with a rubber block fixedly connected to the inner cavity of the placement cylinder.

[0009] Preferably, a large gear is rotatably connected to one side of the fixed plate, and the teeth of the large gear mesh with the first gear.

[0010] Preferably, a motor is fixedly connected to one side of the base plate, the output shaft of the motor passes through to one side of the fixed plate, and the output shaft of the motor is fixedly connected to one side of the large gear.

[0011] Preferably, the inner cavity of the slider is threadedly connected to a threaded block, and one side of the threaded block is fixedly connected to one side of the placement cylinder.

[0012] Preferably, a support column is fixedly connected to one side of the base plate, and a plurality of support columns are provided, with one side of the support column rotatably connected to one side of the fixed plate.

[0013] The advantages of this utility model are:

[0014] This invention fixes multiple watercolor pens in a storage tube and a test paper on a test plate. An adjustable moving block positions the test plate at the pen refill. A motor drives a large gear to rotate, which in turn rotates a first gear, which in turn rotates a second gear. The second gear's rotation causes a connecting rod and a hollow block to rotate, simultaneously rotating a slider and the watercolor pens in the storage tube. The slider's rotation also causes a round rod to move within a guide groove on the surface of a limiting plate. Simultaneously, the rotation of the first gear drives a third gear, whose teeth mesh with those of a fourth gear, causing the fourth gear to rotate. At this time, the limiting plate rotates, ensuring the round rod moves within the guide groove on its surface. The effective movement within the groove allows the slider to slide within the hollow block, causing the watercolor pens fixed in the placement cylinder to move along a spiral trajectory. Specifically, through the cooperation of the limiting plate, hollow block, slider, and round rod, the watercolor pen refills placed in the placement cylinder move along a spiral trajectory. The pen refills move and draw on the test paper fixed on the detection plate. Multiple detection mechanisms are set up, and simultaneous movement and detection can be achieved through large gears and motors. This allows for simultaneous ink dispensing tests on multiple watercolor pen refills, facilitating observation and inspection by staff and improving work efficiency. This solves the problem that due to limitations in testing conditions, most inspection devices can only test each pen refill individually during ink dispensing testing after watercolor pen production, requiring manual sorting and resulting in low work efficiency.

Figure 1-5 A device for detecting ink flow from watercolor pen refills includes a base plate 1, a detection mechanism 2 on one side of the base plate 1, and a fixing mechanism 3 fixedly connected to another side of the base plate 1. The base plate 1 supports the installation of the detection mechanism 2 and the fixing mechanism 3, facilitating their operation. The fixing mechanism 3 fixes the test paper, assisting the subsequent detection mechanism 2 in testing the ink flow of the watercolor pen refills. Multiple detection mechanisms 2 are provided, all located on the upper part of the detection mechanism 2, which can drive the watercolor pen to move along a spiral trajectory, thereby enabling the detection of the watercolor pen refills on the test paper. This allows for simultaneous testing of multiple refills, reducing manual sorting and improving work efficiency.

[0025] The testing mechanism 2 includes a fixing plate 201, which is located on one side of the base plate 1. A first gear 202 and a second gear 203 are rotatably connected to one side of the fixing plate 201. The teeth of the first gear 202 mesh with the teeth of the second gear 203. A third gear 204 is fixedly connected to one side of the first gear 202. A fourth gear 205 is rotatably connected to one side of the second gear 203. The teeth of the fourth gear 205 mesh with the teeth of the third gear 204. A cylinder 20 is fixedly connected to one side of the fourth gear 205. 6. A limiting disk 207 is fixedly connected to the surface of the cylinder 206. A connecting rod 208 is rotatably connected to the inner cavity of the cylinder 206 via a bearing. One side of the connecting rod 208 extends to one side of the fourth gear 205, and one side of the connecting rod 208 is fixedly connected to one side of the second gear 203. A hollow block 209 is fixedly connected to one side of the connecting rod 208. A slider 210 is slidably connected to the inner cavity of the hollow block 209. A round rod 211 is slidably connected to the inner cavity of the limiting disk 207. One side of the round rod 211 is fixedly connected to one side of the slider 210.

[0026] Reference Figure 2 The fixing mechanism 3 includes a fixing rod 301, one side of which is fixedly connected to one side of the base plate 1. A moving block 302 is slidably connected to the surface of the fixing rod 301. A hollow groove 303 is provided on the surface of the fixing rod 301. Several hollow grooves 303 are provided. Bolts 304 are threadedly connected to the inner cavity of the hollow groove 303 and the moving block 302. A detection plate 305 is fixedly connected to one side of the moving block 302.

[0027] The fixing plate 201 can be used to support the first gear 202 and the second gear 203, and facilitates the rotation of the first gear 202 and the second gear 203. The fixing plate 201 can also be used to install other components in multiple sets of detection mechanisms 2, facilitating simultaneous testing of multiple watercolor pens. The first gear 202 and the second gear 203 are both located on the upper part of the fixing plate 201, allowing their teeth to mesh and rotate synchronously, thereby assisting in moving other components in the subsequent detection mechanism 2. The second gear 203 can be used to support the connecting rod 208, and its rotation synchronously drives the connecting rod 208 to rotate as well. The connecting rod 208 can be used to support the hollow block 209, and its rotation drives the hollow block 209 to rotate as well. The hollow block 209 can be used to install the slider 210, facilitating the sliding of the slider 210 within its inner cavity. The bottom of the slider 210 is connected to... The round rod 211 provides some support. When the round rod 211 rotates with the slider 210, it simultaneously squeezes the inner cavity of the limiting disk 207, thereby causing the limiting disk 207 to rotate. The limiting disk 207 is fixed to the upper part of the cylinder 206 and can be used to cooperate with the round rod 211 to define the movement trajectory of the round rod 211 and the slider 210, so that the round rod 211 can drive the slider 210 to move in a spiral trajectory. The cylinder 206 is fixed to one side of the fourth gear 205 and can be used to support the limiting disk 207, thereby assisting the limiting disk 207 to rotate smoothly. When the fourth gear 205 rotates with the cylinder 206, it can mesh with the teeth of the third gear 204, thereby driving the third gear 204 to rotate, thus assisting the watercolor pen to move stably in a spiral trajectory, realizing the ink dispensing test of its pen core, thereby improving its testing efficiency.

It assists in the subsequent detection of ink dispensing of watercolor pens. Multiple bolts 304 are provided for mounting bolts 304. The bolts 304 can cooperate with the moving block 302 and bolts 304 to place the detection plate 305 in a suitable position. The detection plate 305 can be used to fix the detection paper and assist the detection mechanism 2 in detecting watercolor pens, thereby achieving the effect of detecting ink dispensing of pen refills.

[0029] Reference Figure 3 A placement cylinder 4 is provided on one side of the slider 210. There are two placement cylinders 4. A rubber block 5 is fixedly connected to the inner cavity of the placement cylinder 4. The placement cylinder 4 is fixed on the upper part of the slider 210 and can be used to place the watercolor pen to be tested. The rubber block 5 is fixed in the inner cavity of the placement cylinder 4 and can be used to help to fix the watercolor pen stably inside the rubber block 5, thereby assisting in the subsequent ink dispensing test of the watercolor pen.

[0030] Reference Figure 3 A large gear 6 is rotatably connected to one side of the fixed plate 201. The teeth of the large gear 6 mesh with the first gear 202. The large gear 6 is located on the upper part of the fixed plate 201 and can be used to mesh with the teeth of multiple first gears 202 at the same time, thereby driving multiple sets of detection mechanisms 2 to operate, thereby realizing the ink detection of multiple watercolor pen refills and improving work efficiency.

[0031] Reference Figure 2 A motor 7 is fixedly connected to one side of the base plate 1. The output shaft of the motor 7 passes through to one side of the fixed plate 201. The output shaft of the motor 7 is fixedly connected to one side of the large gear 6. The motor 7 can be used as a drive source. Its output shaft can drive the large gear 6 to rotate, thereby enabling the large gear 6 to rotate and drive the detection mechanism 2 to operate, thus realizing the drive of the detection mechanism 2 and assisting in the effect of detecting the ink output of multiple watercolor pen refills.

[0032] Reference Figure 5 The inner cavity of the slider 210 is threadedly connected to a threaded block 8. One side of the threaded block 8 is fixedly connected to one side of the placement cylinder 4. The threaded block 8 can be used to remove the placement cylinder 4 and the rubber block 5 from the upper part of the slider 210 and replace them, thereby enabling the detection of different watercolor pens and improving the effectiveness of the detection mechanism 2.

[0033] Reference Figure 1 A support column 9 is fixedly connected to one side of the base plate 1. Several support columns 9 are provided. One side of the support column 9 is rotatably connected to one side of the fixed plate 201. The support column 9 is located at the lower part of the fixed plate 201 and can be used to support the fixed plate 201, so that the motor 7 can be stably moved to the other side. In addition, multiple support columns 9 can strengthen the support of the fixed plate 201 for other components in the detection mechanism 2, thereby helping to improve the stability of the operation of other components in the detection mechanism 2.

[0034] Working principle: When using this device, the operator can first fix multiple watercolor pens in the inner cavity of the placement tube 4, and then fix the test paper to the lower part of the test plate 305. The adjustable fixing mechanism 3 can move the moving block 302 to move the test plate 305 to the position of the watercolor pen refill. At the same time, the starting motor 7 drives the large gear 6 to rotate. When the large gear 6 rotates, it will mesh with the teeth of the first gear 202, driving the first gear 202 to rotate. When the first gear 202 rotates, it will also mesh with the teeth of the second gear 203. This rotation causes the second gear 203 to rotate. The rotation of the second gear 203 causes the connecting rod 208 and the hollow block 209 connected to the upper part to rotate together. The rotation of the hollow block 209 synchronously causes the slider 210 and the watercolor brush fixed in the placement cylinder 4 to rotate together. Simultaneously, the rotation of the slider 210 also causes the round rod 211 to move within the guide groove on the surface of the limiting plate 207. When the first gear 202 rotates, it simultaneously causes the third gear 204 to rotate. The teeth of the third gear 204 will engage with the fourth gear 205. The meshing of the teeth synchronously drives the fourth gear 205 to rotate. Under the connection of the cylinder 206, the limiting disk 207 will rotate, thereby ensuring that the round rod 211 can move effectively within the guide groove on the surface of the limiting disk 207, allowing it to drive the slider 210 to slide within the hollow block 209. This causes the watercolor pen fixed in the placement cylinder 4 to move in a spiral trajectory. That is, through the cooperation of the limiting disk 207, the hollow block 209, the slider 210, the round rod 211, etc., the watercolor pen refill placed in the placement cylinder 4 moves in a spiral trajectory. The test paper is drawn on the test plate 305 to test the ink flow of the watercolor pen refill. The test mechanism 2 is set with multiple groups, which can be moved and tested simultaneously by the large gear 6 and the motor 7. This allows for simultaneous testing of ink flow of multiple watercolor pen refills, which is convenient for staff to observe and inspect, thus improving work efficiency. This solves the problem that due to the limitations of the test conditions, most inspection devices can only test the pen refills one by one when testing ink flow after the watercolor pen manufacturing process, and manual sorting is required, resulting in low work efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
