Description

Technical Field

[0001] This utility model relates to a marker lifespan testing device. Background Technology

[0002] Some educational, creative, artistic, personalized, or reusable toys come with markers to facilitate drawing, coloring numbers, or doodling. However, toy manufacturers do not produce markers, so the lifespan of the markers purchased cannot be determined without sampling and lifespan testing.

[0003] Currently, toy manufacturers only conduct manual tests on the lifespan of sampled markers. Testers must hold the marker and repeatedly draw lines on paper until the ink runs out. This process is extremely tedious and time-consuming, and manual drawing involves many uncontrollable variables. For example, different people, or even the same person at different times, cannot maintain consistent pressure when drawing. Furthermore, the speed of drawing affects the amount of ink consumed per unit time. Additionally, the consistency, length, and shape of the handwriting vary among different testers, making it impossible to accurately determine the marker's lifespan. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a marker lifespan testing device.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A marker lifespan testing device includes a base with a built-in PLC controller and control buttons, a vertical plate fixed above the base, a paper feeding roller mounted on one side of the front of the vertical plate via a bearing seat, a first guide roller mounted on the vertical plate and located below the paper feeding roller, a paper pressing mechanism mounted on the vertical plate and flush with the first guide roller, a writing board mounted on the vertical plate and located above the paper pressing mechanism, a second guide roller mounted on the vertical plate and flush with the paper pressing mechanism, a paper taking-up roller mounted on the vertical plate and flush with the writing board via a bearing seat, a winding motor fixedly mounted on the back of the vertical plate and whose output end passes through the vertical plate and connects to the paper taking-up roller, and a marker drawing mechanism located above the writing board and fixed to the vertical plate.

[0008] Preferably, paper support rollers are provided on both sides of the writing board, and the paper support rollers are fixedly installed with the upright plate, and the upright plate is flush with the writing board.

[0009] Preferably, the marker drawing mechanism includes a fixed plate bolted to the upright plate, guide rails fixed to the upper and lower ends of the outer side of the fixed plate by screws, a telescopic cylinder fixed to the middle of the inner side of the fixed plate by screws, a first side plate assembled with the guide rails by a slider, a bottom plate located below the fixed plate and fixed to the first side plate by screws, a top plate located above the fixed plate and fixed to the first side plate by screws, a second side plate whose upper and lower sides are fixed to the bottom plate and the top plate by screws respectively, a connecting seat fixed to the second side plate by bolts and fixed to the output end of the telescopic cylinder, and a clamping assembly disposed on the outer side of the first side plate and located above the writing board.

[0010] Furthermore, the first side plate, the second side plate, the bottom plate, and the top plate form a rectangular sleeve.

[0011] Furthermore, the clamping assembly includes a limiting block fixed to the first side plate, a positioning block fixed to the first side plate and located above the limiting block, connecting studs located at both ends of the positioning block and penetrating the positioning block, a lower pressure block located below the positioning block and connected to the connecting studs, a second spring fitted on the connecting studs, a clamping block fixedly mounted on the side of the lower pressure block by screws, a placement hole opened on the clamping block, and a clamping stud for clamping the marker pen after penetrating the clamping block and being screwed into the placement hole.

[0012] The beneficial effects of this invention are as follows: This invention realizes a fully automated process from paper roll feeding, pressing, marking to rewinding, greatly reducing manual intervention, improving testing efficiency, and making it suitable for batch testing. The paper pressing mechanism ensures stable paper roll tension, the writing board and paper support rollers ensure a flat paper surface, and the marking mechanism provides precise reciprocating motion.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0019] Example

[0020] like Figure 1-5 As shown, a marker lifespan testing device includes a base 1 with a built-in PLC controller and control buttons, a vertical plate 2 fixed above the base 1, a paper feeding roller 3 mounted on one side of the front of the vertical plate 2 via a bearing seat, a first guide roller 4 mounted on the vertical plate 2 and located below the side of the paper feeding roller 3, a paper pressing mechanism 5 mounted on the vertical plate 2 and flush with the first guide roller 4, a writing board 6 mounted on the vertical plate 2 and located above the paper pressing mechanism 5, a second guide roller 7 mounted on the vertical plate 2 and flush with the paper pressing mechanism 5, a paper taking roller 8 mounted on the vertical plate 2 and flush with the writing board 6 via a bearing seat, a winding motor 9 fixedly mounted on the back of the vertical plate 2 and whose output end passes through the vertical plate 2 and connects to the paper taking roller 8, and a marker drawing mechanism 10 located above the writing board 6 and fixed to the vertical plate 2.

[0021] It should be further explained that the paper roll is automatically fed by the take-up roller 8 driven by the rewind motor 9, avoiding the tediousness of frequent manual paper changes and improving testing efficiency. The continuous feeding of the paper roll, combined with the reciprocating motion of the marker line drawing machine 10, can simulate the continuous line drawing scenario of a marker in actual use, making the test results closer to the actual service life. In addition, the built-in PLC controller and control buttons allow users to preset test parameters such as line drawing speed and stroke, ensuring the repeatability and accuracy of the test process. Moreover, the components are reasonably arranged on the upright plate, making the device compact, occupying little space, and easy to install and maintain.

[0022] The paper pressing mechanism 5 includes a rectangular bar 51 with a screw hole in the center and through holes at both ends; a movable pressing bar 52 with a mounting groove in front of the rectangular bar 51; a single-headed cylinder 53 welded to one end of the movable pressing bar 52 and passing through the through holes at both ends of the rectangular bar 51 and fixed by nuts; a first spring 54 fitted on the single-headed cylinder 53 for lifting the movable pressing bar 52; a paper pressing roller 55 installed in the mounting groove of the movable pressing bar 52; and a limiting screw 56 passing through the central screw hole of the rectangular bar 51 and abutting against the movable pressing bar 52 at its end. Specifically, the rectangular bar 51 is fixed to the upright plate 2 with screws. The first spring 54, in conjunction with the single-headed cylinder 53, can lift the movable pressing bar 52, so that the paper pressing roller 55 can press the paper roll tightly and prevent the paper roll from loosening during the conveying process. The limiting screw 56 can adjust the length, thereby limiting the movable pressing bar 52 from excessively retracting under strong tension of the paper roll.

[0023] In the structure of the paper pressing mechanism 5, the first spring 54, in conjunction with the single-headed cylinder 53, can continuously push up the movable pressure bar 52, so that the paper pressing roller 55 always presses the paper roll tightly, preventing the paper roll from loosening or slipping during the conveying process, and ensuring the accuracy of the marking position. The first spring 54 allows the paper pressing mechanism 5 to automatically adjust the pressure according to the thickness or tension of the paper roll, adapting to different specifications of paper rolls. The limit screw 56 can be adjusted in length to limit the movable pressure bar 52 from excessively retracting when the paper roll tension is too high, preventing damage to the mechanism or breakage of the paper roll, and improving the reliability and safety of the device.

[0024] Paper support rollers 61 are provided on both sides of the writing board 6. The paper support rollers 61 are fixedly installed with the upright plate 2, and the upright plate 2 is flush with the writing board 6. Specifically, the flushness of the paper support rollers 61 with the writing board 6 provides additional support points for the paper roll, preventing the paper roll from drooping or shifting above the writing board 6, ensuring that the paper surface is flat during the marking process. In addition, the paper support rollers 61 make the paper roll transport smoother, reduce friction with the writing board, avoid paper roll wear or scratches, and improve the consistency of the test.

[0025] The marker drawing mechanism 10 includes a fixed plate 101 bolted to the upright plate 2, guide rails 102 screwed to the upper and lower ends of the outer side of the fixed plate 101, a telescopic cylinder 103 screwed to the middle of the inner side of the fixed plate 101, a first side plate 104 assembled with the guide rails 102 via a slider, a bottom plate 105 located below the fixed plate 101 and fixed to the first side plate 104 by screws, a top plate 106 located above the fixed plate 101 and fixed to the first side plate 104 by screws, a second side plate 107 fixed to the bottom plate 105 and the top plate 106 respectively by screws on its upper and lower sides, a connecting seat 108 bolted to the second side plate 107 and fixed to the output end of the telescopic cylinder 103, and a clamping assembly 109 located on the outer side of the first side plate 104 and above the writing board 6.

[0026] It should be further explained that the first side plate 104, the second side plate 107, the bottom plate 105 and the top plate 106 form a rectangular sleeve. Specifically, it can not only be movably assembled with the fixed plate 101, but also facilitate the telescopic cylinder 103 to drive the entire rectangular sleeve to move back and forth along the fixed plate 101, so that the marker fixed on the clamping assembly 109 can draw fold lines on the paper roll being transported.

[0027] Specifically, the slider assembly on the guide rail 102 and the first side plate 104 ensures that the marker moves back and forth in a straight line under the drive of the telescopic cylinder 103, with accurate drawing trajectory, simulating the drawing of broken lines in actual use. The first side plate 104, the second side plate 107, the bottom plate 105 and the top plate 106 form a rectangular sleeve, making the entire mechanism structure stable, easy to assemble and maintain, and ensuring motion stability. The connecting seat 108 connects the output end of the telescopic cylinder 103 to the second side plate 107, transmitting power smoothly, reducing impact and extending cylinder life.

[0028] The clamping assembly 109 includes a limiting block 1091 fixed to the first side plate 104, a positioning block 1092 fixed to the first side plate 104 and located above the limiting block 1091, a connecting stud 1093 located at both ends of the positioning block 1092 and penetrating the positioning block 1092, a lower pressing block 1094 located below the positioning block 1092 and connected to the connecting stud 1093, a second spring 1095 fitted on the connecting stud 1093, a clamping block 1096 fixedly installed on the side of the lower pressing block 1094 by screws, a placement hole 1097 opened on the clamping block 1096, and a clamping stud 1098 for clamping the marker pen after penetrating the clamping block 1096 and being screwed into the placement hole 1097. Specifically, through the cooperation of the second spring 1095 and the connecting stud 1093, the lower pressure block 1094 and the clamping block 1096 can adaptively clamp markers of different diameters to prevent the markers from loosening or falling off during the test. The clamping stud 1098 can finely adjust the clamping force to adapt to various marker models. In addition, the clamping assembly 109 is simple in design and easy to operate, allowing for quick replacement of markers and improving testing efficiency.

[0029] It should be further explained that the PLC controller built into the base 1 connects the winding motor 9 and the telescopic cylinder 103, thereby effectively controlling the winding speed of the winding motor 9 and controlling the telescopic cylinder 103 to drive the entire rectangular sleeve to move back and forth along the fixed plate 101, so that the marker fixed on the clamping assembly 109 draws fold lines on the paper roll being transported.
