[0030] Embodiment:

[0031] For example Figures 1 to 3As shown, a kind of marker wind-drying performance testing device, including test box 11, the test cavity 12 of opening right is set in the test box 11, the front side of the test cavity 12 is equipped with observation window 21, so that operator can more comprehensive observation test condition during testing, timer (not shown in drawing) that can transmit electrical signal to the control equipment (not shown in drawing) capable of showing various data is installed in the test cavity 12, lifting cylinder 30 is installed on the top wall of the test cavity 12, the piston rod end of the lifting cylinder 30 is fixedly connected with connecting seat 23, miniature camera 33 capable of transmitting picture to the control equipment is installed on the lower side of the connecting seat 23, fixed clamp 24 is fixedly connected on the rear side of the connecting seat 23, movable clamp 25 capable of moving back and forth is provided on the rear side of the fixed clamp 24, the side of the fixed clamp 24 and the movable clamp 25 opposite each other is equipped with arc slot 26, the connecting mode of the fixed clamp 24 and the movable clamp 25 is: the through hole 27 is symmetrically set in the fixed clamp 24, each through hole 27 is rotatably connected with screw rod 28, and the movable clamp 25 is symmetrically provided with screw hole 29, and the screw rod 28 is screw connected in the screw hole 29 on the same side.

[0032] Before starting test, operator first abuts the curved surface upper side of marker on the inner wall of the arc slot 26 set in the fixed clamp 24, then operator rotates the left and right screw rods 28 respectively, so that the movable clamp 25 approaches the fixed clamp 24, until the movable clamp 25 abuts on the curved surface upper side of marker, to achieve the effect of fixing marker.

[0033] Rotating shaft 16 is rotatably connected in the left side wall of the test cavity 12, the curved surface side wall of the rotating shaft 16 is provided with paper roll 17, two transmission rollers 15 are rotatably connected in the test cavity 12, and support plate 22 is fixed on the rear side wall of the test cavity 12, the support plate 22 is located between the two transmission rollers 15 and below the connecting seat 23, air expansion shaft 18 is rotatably connected on the lower side of the test cavity 12, motor 19 for driving the air expansion shaft 18 is installed on the test box 11, paper tube 20 is sleeved on the curved surface side wall of the air expansion shaft 18.

[0034] The installation of the paper roll 17 is as follows: the right side surface of the rotating shaft 16 is internally threaded connected with a limiting bolt 31, the head diameter of the limiting bolt 31 is larger than the diameter of the rotating shaft 16, and the inner curved surface of the rotating shaft 16 is fixed with a limiting ring 32 with the same outer diameter as the head diameter of the limiting bolt 31. The operator sets the paper roll 17 on the curved surface of the rotating shaft 16, and makes the left outer edge of the paper roll 17 abut against the limiting ring 32, and then threadedly connects the limiting bolt 31 with the right side surface of the rotating shaft 16, and makes the head of the limiting bolt 31 abut against the right outer edge of the paper roll 17, so as to fix the paper roll 17, and prevent the paper roll 17 from falling off or deviating from the rotating shaft 16 during the test.

[0035] During the test, the marker is vertically hung in the test cavity 12, the rear wall of the test cavity 12 is internally provided with an air pipe 13 connected with an external air conveying device (not shown), so that the air pipe 13 can continuously blow air flow to the tip of the marker. When the marker is placed for a period of time, the lifting cylinder 30 drives the marker to move downward through the connecting seat 23, so that the tip of the marker abuts against the surface of the paper tape. At this time, the motor 19 drives the air expansion shaft 18 to rotate, so that the paper roll 17 draws out the paper tape, and drives the paper tape below the marker to move from back to front, so that the marker draws lines on the surface of the paper tape;

[0036] Then the marker moves upward, the paper tape below the marker continues to move forward, the marker continues to be placed and blown, and the above steps are repeated, and the whole process is recorded by the miniature camera 33. The operator observes the time when the marker appears to run out of ink through the miniature camera 33, and corresponds the signal transmitted by the timer, so as to judge whether the anti-drying performance of the marker is qualified.

[0037] The waste paper written by the marker is collected on the paper cylinder 20 through transmission, so as to ensure that the test environment is clean and avoid that the test environment is messy. When the paper tape on the paper roll 17 is used up, the operator opens the movable door 21, takes down the paper roll 17 with the used paper tape and replaces a new paper roll 17, and then takes down the paper cylinder 20 with the waste paper tape wound thereon from the air expansion shaft 18, and replaces a new paper cylinder 20.

[0038] Meanwhile, it needs to be pointed out that the terms indicated by the utility model, such as "front", "rear", "vertical", "horizontal" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element indicated must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection scope of the utility model.

[0039] The above only describes the preferred embodiments of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement and the like made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
