[0025] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0026] Combined with Figure 1 and 2A small laboratory sample thickness determination device of this embodiment includes a workbench 1, a pressure roller 2 is arranged above the workbench 1, and the height of the pressure roller 2 above the workbench 1 is adjustable to adapt to the adjustment of different thicknesses of the sample, the pressure roller 2 is installed on the pressure roller bracket 3, the pressure roller bracket 3 is an inverted U-shaped structure, and the two ends of the pressure roller 2 are rotatably connected to the pressure roller bracket 3, and a top plate 4 is arranged above the pressure roller bracket 3, and the top plate 4 is arranged with an upper and lower interval with the pressure roller bracket 3. The top plate 4 extends along the length direction of the workbench 1 and is fixedly connected to the workbench 1 at both ends through vertical plates, and a slider 5 is slidably connected to the upper end surface of the top plate 4 A slide rail or slide groove cooperating with the slider 5 is provided on the top plate 4 along the length direction of the workbench 1, a screw sleeve 6 is fixedly connected to the slider 5, and an internal thread is provided on the inner circumferential wall of the screw sleeve 6. A screw rod 7 is rotatably connected to the pressure roller bracket 3, and the screw rod 7 is threadedly connected to the screw sleeve 6. A guide rod 8 is also connected to the pressure roller bracket 3. The guide rod 8 is arranged parallel to the screw rod 7 and is perpendicular to the upper end surface of the workbench 1. A slide groove 9 cooperating with the guide rod 8 is provided on the top plate 4, and the slide groove 9 is arranged along the length direction of the workbench 1. The top plate 4 also has an avoidance groove cooperating with the screw rod 7, so that the screw rod 7 can slide on the top rod 4 with the slider 5.

[0027] When the present small laboratory sample thickness determination device is in use, the operator adjusts the thickness determination height of the pressing roller 2 by rotating the screw rod 7. The pressing roller 2 can be kept at a fixed height by simply stopping rotating the screw rod 7. The main operating steps are as follows: the sample to be thickness determined is placed on the workbench 1, with the head placed under the pressing roller 2. The required thickness of the sample is controlled by adjusting the height of the pressing roller 2. The sample is thickness-determined by manually pushing the slider 5 to slide. Under a certain traction force, the sample can achieve continuous thickness determination under the set thickness.

[0028] This type of laboratory sample thickness determination device has a simple structure, stable thickness determination effect, low equipment cost, and a stable structure that is not easily damaged. It is suitable for purchase and use in small laboratories.

[0029] As a preferred embodiment of the present invention, the top of the screw rod 7 is connected with a hand-tightening portion 10, which is a columnar structure with a diameter larger than the screw rod 7 and anti-slip grooves on the surface. It is mainly used to facilitate the operator to manually rotate the screw rod 7 to adjust the height of the pressure roller 2.

[0030] As a preferred embodiment of the present invention, a measuring component for measuring the height of the pressure roller 2 is also included. In this embodiment, the measuring component includes a distance sensor and a display screen electrically connected to the distance sensor. The height of the pressure roller 2 is measured by the distance sensor, and the numerical value is displayed on the display screen, so that the operator can observe the height of the pressure roller 2 in real time when adjusting the height, with higher accuracy.

[0031] As a preferred solution of the utility model, the distance sensor is arranged on the lower end surface of the top plate 4, and the distance sensor measures the height difference between it and the pressure roller bracket 3. Since the height difference between the pressure roller bracket 3 and the pressure roller 2 is constant, the height difference between the workbench 1 and the top plate 4 is also constant, so the height of the pressure roller 2 can be directly calculated through the above data.

[0032] As a preferred embodiment of the present invention, a detection roller 12 is provided on the pressure roller bracket 3 at the rear side of the pressure roller 2. During thickness pressing, the pressure roller 2 contacts the sample before the detection roller 12. The detection roller 12 and the pressure roller 2 are arranged at the same height. The detection roller 12 is movably connected to the pressure roller bracket 3 up and down. The pressure roller bracket 3 is also provided with a sensing structure for detecting whether the detection roller 12 can move up and down. If the height of the sample rebounds after thickness pressing, the detection roller 12 will bounce upward when it contacts it later. At this time, it is judged that the thickness pressing is unqualified and it is necessary to press the thickness again until the detection roller 12 does not move upward when contacting the sample.

[0033] As a preferred embodiment of the utility model, a movable groove 13 is provided on the pressure roller bracket 3 along its height direction, and a rotating shaft 14 is connected to the end of the detection roller 12. The rotating shaft 14 is arranged at the axial position of the detection roller 12, and the rotating shaft 14 is rotatable and movable up and down in the movable groove 13. The diameter of the rotating shaft 14 is consistent with the groove width of the movable groove 13. The sensing structure includes a pressure sensor 15, a spring 16 and a rotating shaft pressure ring 17 which are arranged from top to bottom in the movable groove 13. The spring 16 is in a compressed force storage form, and the rotating shaft pressure ring 17 abuts against the upper end of the rotating shaft 14. The lower end surface of the rotating shaft pressure ring 17 is provided with an arc surface that cooperates with the rotating shaft 14. When the detection roller 12 moves upward, it drives the rotating shaft 14 to move upward, so that the spring 16 is compressed, and the pressure signal sensed by the pressure sensor 15 produces a large fluctuation, and then it is judged as unqualified pressure thickness.

[0034] As a preferred solution of the utility model, an operating surface table 18 is detachably connected to the workbench 1. The operating surface table 18 is a flat plate. A groove for accommodating the operating surface table 18 is provided on the workbench 1. This is mainly to facilitate the operator to remove the thickened sample connected to the operating surface table 18 directly from the workbench 1, to facilitate subsequent curing operations, and to avoid deformation of the sample during the transfer process.

[0035] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
