With the development of technology and the popularization of market applications, the application scenarios of LED display screens have been greatly developed and enriched, such as commercial media, cultural performance markets, stadiums, information dissemination, news release, securities trading, etc. LED display screens can be divided into conventional screens for facade display and floor tiles screens laid on walking surfaces according to different installation applications. Floor tiles screens have higher requirements for bearing pressure performance, but there is a lack of devices for detecting the bearing pressure performance of floor tiles screens on the market.

[0033] Therefore, the present utility model provides a rolling test machine that can perform the bearing pressure performance test of the floor tiles screen.

[0034] Refer to Figure 1 and Figure 2 In a rolling test machine according to an embodiment of the present utility model, it includes a pressing mechanism 100 and a mounting mechanism 200. Among them, the pressing mechanism 100 can be adjusted up and down, and wheels are rotatably arranged at the lower end of the pressing mechanism 100. Therefore, the wheels can move up and down through the up and down adjustment of the pressing mechanism 100. The mounting mechanism 200 is located below the pressing mechanism 100, and the mounting mechanism 200 is provided with a tooling for mounting the floor tiles screen. Moreover, the pressing mechanism 100 and the mounting mechanism 200 can be relatively moved and adjusted in the horizontal direction.

[0035] In the rolling test machine of the present utility model, only need to place the floor tiles screen to be tested on the tooling, then the pressing mechanism 100 can be used to control the wheels to press on the floor tiles screen, and the relative movement of the pressing mechanism 100 and the mounting mechanism 200 is used to simulate the situation of vehicle rolling, so as to realize the bearing pressure performance test of the floor tiles screen. It can be understood that the downward pressure of the wheels and the number of rolling times can be flexibly set according to needs, so the bearing pressure performance of the floor tiles screen can be effectively obtained.

[0036] Refer to Figure 2 In some embodiments of the present utility model, the rolling test machine includes a workbench 201, the mounting mechanism 200 is arranged on the tabletop of the workbench 201, and the pressing mechanism 100 is erected above the workbench 201. By setting the workbench 201 for installing the pressing mechanism 100 and the mounting mechanism 200, it is beneficial to improve the integrity of the equipment. The workbench 201 can be set at a certain height so that the operation height is convenient for workers to install and remove the floor tiles screen, or the workbench 201 can be set flush with the ground to reduce the overall weight and reduce consumables, which is beneficial to reducing the equipment cost.

[0037] Refer to Figure 2, in some embodiments of the present utility model, the pressing mechanism 100 includes a gantry 101, an adjusting seat 102, a lifting seat 103 and a lifting cylinder. The gantry 101 specifically includes two columns 1011 and a cross beam 1012 connected to the upper ends of the two columns 1011. The adjusting seat 102 is installed on the cross beam 1012. The lifting seat 103 is connected to the adjusting seat 102 in a lift-adjustable manner and is driven by the lifting cylinder. Wheels are rotatably arranged at the bottom of the lifting seat 103. During operation, the wheels are controlled by the lifting cylinder to move downward until they abut against the floor tile screen. Then, when the pressing mechanism 100 and the installation mechanism 200 move relative to each other, the wheels will roll on the floor tile screen, thereby simulating the stress condition of vehicle rolling. It is only necessary to determine whether the floor tile screen is functioning properly and displaying normally to obtain the bearing capacity of the floor tile screen through the test.

[0038] It can be understood that the relative movement direction of the pressing mechanism 100 and the installation mechanism 200 is perpendicular to the axis of the wheels. Of course, the wheels can also be set as a universal wheel structure to adapt to movements in different directions.

[0039] In some embodiments of the present utility model, the adjusting seat 102 is connected to the cross beam 1012 in a manner that can be adjusted along the length direction of the cross beam 1012. In this way, the wheels can be adjusted to move along the direction perpendicular to the rolled floor tile screen, and different positions of the floor tile screen can be rolled. This movement adjustment can be achieved by an electric control method or by manual disassembly and assembly, which will not be described in detail here.

[0040] Refer to Figure 3 , in some embodiments of the present utility model, the adjusting seat 102 is provided with a first adjusting plate 1021 and a second adjusting plate 1022.

In this embodiment, the adjusting seat 102 and the cross beam 1012 are clamped and fixed. Since the direction of the acting force is along the vertical direction when the wheels roll on the floor tile screen, the installation stability of the adjusting seat 102 can meet the requirements of the rolling test. On the basis of the structure of this embodiment, if it is necessary to change the position of the adjusting seat 102 along the length direction of the cross beam 1012, only the connection between the first adjusting plate 1021 and the second adjusting plate 1022 needs to be loosened.

[0041] Refer to Figure 3, in some embodiments of the present utility model, four guide posts 1031 are provided at the upper end of the lifting seat 103, and the four guide posts 1031 pass through the four vertex positions of the first adjusting plate 1021 and the second adjusting plate 1022 from both sides of the cross beam 1012. The lifting cylinder is connected between the lifting seat 103 and the adjusting seat 102. With the structural arrangement of this embodiment, the lifting seat 103 is guided by the four guide posts 1031, which can improve the structural strength and the stability during wheel rolling.

[0042] Referring to Figure 1 and Figure 2 , in some embodiments of the present utility model, the installation mechanism 200 is provided with a slide rail 202, and the tooling is slidably arranged on the slide rail 202. The direction of the slide rail 202 is perpendicular to the rotation axis of the wheel. Thus, when the floor tile screen is fixed on the tooling, by moving the tooling on the slide rail 202, the floor tile screen is driven to pass under the wheel. When the wheel moves downward to abut against the floor tile screen, the rolling test can be successfully completed.

[0043] In some embodiments of the present utility model, the installation mechanism 200 is provided with a driving part, and the driving part is connected to the tooling for driving the tooling to move on the slide rail 202. The driving part can adopt a cylinder or other structures capable of realizing linear reciprocating driving.

[0044] Referring to Figure 2 , further, in some embodiments, the tooling includes a bracket (hidden in the figure), and a plurality of support surfaces are provided at the upper end of the bracket for supporting the floor tile screen. At the same time, limiting parts 203 are arranged on opposite sides or adjacent sides of the bracket. The bottom of the bracket is slidably connected to the slide rail 202. During operation, the operator only needs to place the floor tile screen on the bracket, and the floor tile screen can be quickly positioned through the support of the support surfaces and the limitation of the limiting parts 203, and then the rolling test is carried out based on the movement of the bracket. Or further, a quick-release connecting piece is arranged between the bracket and the floor tile screen to fix the floor tile screen on the bracket, and then the rolling test is carried out.

[0045] In some embodiments of the present utility model, the rolling test machine further includes a control end 300, and the control end 300 is connected to the pressing mechanism 100 and the installation mechanism 200 for controlling the operation of the pressing mechanism 100 and the installation mechanism 200.

[0046] Further, the installation mechanism 200 is further provided with a power connection component, and the power connection component is used for connecting the floor tile screen for power supply and display.

[0047] Further, the rolling testing machine is provided with two mounting mechanisms 200, and the rolling testing machine is correspondingly provided with image acquisition or monitoring for the two mounting mechanisms 200. During operation, a sample is placed on one mounting mechanism 200, and a test piece is placed on the other mounting mechanism 200, and both are powered on for display. The number of rolling times (i.e., the number of reciprocating movements of the tooling along the slide rail 202) is set, and the downward pressure of the wheel is set. Then, the rolling test is started. During the test, by comparing whether the display of the test piece and the placed sample is abnormal, the pressure-bearing performance of the test piece can be obtained whether it is qualified.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
