Description

Technical Field

[0001] This application relates to the field of testing technology, specifically to an automatic testing device for PVC sheets. Background Technology

[0002] The PVC sheet automatic inspection device is an automated equipment that integrates mechanics, electronics, optics and software algorithms. It is used to efficiently and accurately detect the quality defects (such as cracks, scratches, bubbles, uneven thickness) and physical properties (such as wear resistance, impact resistance, bending strength) of polyvinyl chloride (PVC) sheets.

[0003] For example, patent CN211042935U discloses a metal sheet tensile strength testing device. This patent uses two clamps to hold and fix the metal sheet. Then, the motor rotates, which drives the second lead screw to rotate, causing the moving block to move upward, which in turn drives the support block to move upward, thereby pulling the upper fixed clamp upward to perform a tensile operation on the metal sheet, thus conducting a tensile test.

[0004] Traditional testing equipment typically uses separate devices to test tensile strength and impact resistance, which is cumbersome and inefficient. More importantly, existing technology cannot simulate the scenarios in which PVC sheets may be subjected to combined tensile and impact forces in actual use (for example, PVC sheets in building curtain walls and exterior wall decoration need to withstand continuous wind pressure tensile stress and sudden flying stone / hail impact loads at the same time), resulting in deviations between test results and actual performance.

[0005] Therefore, it is necessary to provide an automatic detection device for PVC sheets to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0037] like Figures 1-3As shown, this application provides an automatic testing device for PVC sheets. The automatic testing device is mainly used for tensile testing of PVC sheets. The automatic testing device includes a bracket 1, and a housing 2 is fixedly installed on the upper end of the bracket 1. At the same time, a box 3 is fixedly installed on the upper end of the bracket 1 near the housing 2. In order to perform tensile testing on PVC sheets, a tensioning mechanism 4 is provided inside the box 3. The tensioning mechanism 4 includes a motor 40 fixedly installed inside the housing 2. A small sprocket 41 is fixedly installed on the output end of the motor 40, so that the motor 40 can drive the small sprocket 41 to rotate.

[0038] Furthermore, a screw 44 is installed in the bearing inside the housing 3. A large sprocket 43 is fixedly installed at the bottom of the screw 44. A chain 42 is provided between the large sprocket 43 and the small sprocket 41 for transmission. Thus, when the small sprocket 41 rotates, the chain 42 can drive the large sprocket 43 to rotate, thereby driving the screw 44 to rotate synchronously.

[0039] Furthermore, a vertical guide rod 45 is fixedly installed inside the housing 3. A pull plate 46 is slidably mounted on the guide rod 45. The pull plate 46 is threadedly connected to the screw 44, so that when the screw 44 rotates, it can drive the pull plate 46 to slide along the direction of the guide rod 45.

[0040] like Figure 4 As shown, a sensor 47 is fixedly installed at the lower end of the pull plate 46. This sensor 47 is a tension sensor to collect the tension force on the pull plate 46 in real time. At the same time, a first locking block 49 is fixedly installed at the other end of the sensor 47. The first locking block 49 is provided with a first locking groove (not shown in the figure). The first locking groove is used to place PVC sheet. It should be noted that a bolt passing through the locking groove can be provided on the side of the first locking block 49. At the same time, a process hole is opened on the PVC sheet, so that the PVC sheet can be fixed by locking the process hole with the bolt.

[0041] Meanwhile, a second locking block 48 is fixedly installed at the bottom inside the box 3. The upper end of the second locking block 48 is provided with a second locking groove (not shown in the figure). The second locking groove is used to clamp the other end of the PVC sheet (the clamping method is similar to that of the first locking groove). Thus, the two ends of the PVC sheet are clamped through the first locking groove and the second locking groove.

[0042] Therefore, when a tensile test is required on the PVC sheet, both ends of the PVC sheet are fixedly installed in the first and second slots respectively. Then, the motor 40 drives the pull plate 46 to move vertically upward. The reading of the sensor 47 causes the tensile force on the PVC sheet to continuously increase. When the tensile force displayed by the sensor 47 reaches the preset value, if the PVC sheet does not break, it means that the PVC sheet is qualified; otherwise, the PVC sheet is unqualified.

[0043] To simulate the impact of PVC sheets being stretched, such as Figures 4-5 As shown, an impact mechanism 5 is provided at the bottom of the box 3. The impact mechanism 5 includes a slide rail 51 fixedly installed at the bottom of the box 3, a slider 52 slidably installed on the slide rail 51, and a cylinder 50 fixedly installed on one side inside the box 3. The output end of the cylinder 50 is fixedly connected to the slider 52, so that the cylinder 50 can be activated to push the slider 52 to move along the slide rail 51.

[0044] Furthermore, a column 53 is fixedly installed on the upper end of the slider 52, and a hammer 54 is fixedly installed on the column 53. The impact end of the hammer 54 is set towards the PVC sheet, so that when the PVC sheet is subjected to tensile testing, the cylinder 50 can be activated to use a constant force to push the slider 52, causing the hammer 54 to impact along the slide rail 51 until the impact end of the hammer 54 contacts the surface of the PVC sheet. The PVC sheet can be judged by observing whether there are cracks on the surface of the PVC sheet. That is, if there are no cracks, the PVC sheet is qualified; otherwise, the PVC sheet is unqualified.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
