Description

Technical Field

[0001] This application relates to the technical field of artificial leather production and testing equipment, specifically an artificial leather surface hardness testing device. Background Technology

[0002] Artificial leather is a plastic product that looks and feels like leather and can be used as a substitute. It is usually made by coating a fabric base with synthetic resin and various plastic additives. The device used to test the softness and hardness of artificial leather is called a softness and hardness testing device.

[0003] An existing patent (publication number: CN216560106U) discloses a softness and hardness testing device for artificial leather production, belonging to the technical field of artificial leather production testing equipment. It includes a main body, with support rods fixedly installed at the four corners of the lower outer surface of the main body. Self-locking casters are fixedly installed on the lower outer surface of the support rods. Clamping components are fixedly installed at the four corners of the upper outer surface of the main body. A moving component is fixedly installed on the right side of the upper outer surface of the main body. A mounting frame is fixedly installed on the upper part of the moving component. A first cylinder is fixedly installed on the lower outer surface of the mounting frame. A testing instrument is fixedly installed on the lower outer surface of the first cylinder. A test seat is fixedly installed in the middle of the upper outer surface of the main body. This invention provides a softness and hardness testing device for artificial leather production. The moving component facilitates testing at multiple points, and the test seat facilitates quick and stable clamping and fixing of the leather.

[0004] While the device in the aforementioned comparative document has solved the problems of unstable clamping effect, lack of convenient adjustment, and insufficient accuracy in detecting only one point, it lacks a protective structure, making it inconvenient to protect when not in use. Furthermore, it lacks a leveling function, making it inconvenient to adjust its levelness. To address these issues, a device for testing the surface hardness of artificial leather is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a surface hardness testing device for artificial leather, which has advantages such as a protective structure and a leveling function, thus solving the problems of inconvenience in protecting the device and inconvenience in adjusting its level.

[0006] To achieve the above objectives, this application provides the following technical solution: a surface hardness testing device for artificial leather, comprising a base plate and a protective cover, wherein a limiting strip, a first electric slide rail, an adjustment box and a controller are fixedly connected to the top of the base plate, and a snap-fit ​​strip is fixedly connected to the bottom of the protective cover; there are two limiting strips, and the snap-fit ​​strip is snapped between the two limiting strips. A level bubble is fixedly connected to the top of the adjustment box, and adjusting bolts are fixedly connected to the four corners of the bottom of the base plate. Adjusting screws are threaded onto the surface of the adjusting bolts, and rotating blocks are fixedly connected to the surface of the adjusting screws. A support plate is fixedly connected to the bottom of the rotating blocks, and an anti-slip pad is fixedly connected to the bottom of the support plate.

[0007] With the above scheme, by setting up a protective cover, when the device is not in use, the protective cover is placed on top of the base plate, and the locking strip is locked between the two limiting strips. After locking, the protective cover can cover the test area, preventing external interference or accidental touch by the operator, thus facilitating protection. Through the cooperation of the locking strip and the limiting strip, the protective cover can be quickly installed or removed. By setting up rotating blocks and a level bubble, people can observe the level bubble and then rotate multiple rotating blocks to allow the adjusting screw to rotate and move on the surface of the adjusting bolt, thereby adjusting the levelness of the device.

[0008] Furthermore, the adjustment box has two movable rods slidably connected inside, a U-shaped plate is fixedly connected to the top of the movable rods, two limiting rods are slidably connected to the top of the U-shaped plate, and a pressure plate is fixedly connected to the bottom of the limiting rods.

[0009] By using the above method, and by setting a limiting rod to guide the movement trajectory of the lower pressure plate vertically, the lower pressure plate can be prevented from tilting, ensuring that the pressure is applied vertically to the sample surface.

[0010] Furthermore, multiple pressure strips are fixedly connected to the bottom of the U-shaped plate and the bottom of the lower pressure plate.

[0011] The above method allows for multi-point contact with the sample and the application of local pressure by setting pressure strips.

[0012] Furthermore, a threaded cap is fixedly connected to the top of the U-shaped plate, and a rotating bolt is threaded inside the threaded cap. A knob and a top block are fixedly connected to the top and bottom of the rotating bolt, respectively. The bottom of the top block overlaps the top of the lower pressure plate. A connecting spring is sleeved on the surface of the limiting rod, and the two ends of the connecting spring are fixedly connected to the top of the inside of the U-shaped plate and the top of the lower pressure plate, respectively.

[0013] With the above solution, by setting a knob, people can rotate the knob to push the lower pressure plate down, and by moving the lower pressure plate down, the artificial leather can be clamped and fixed.

[0014] Furthermore, a first electric slider is slidably connected inside the first electric slide rail, and an L-shaped support rod is fixedly connected to the top of the first electric slider.

[0015] The above scheme expands the range of left and right movement of the detection head by setting a first electric slide rail and a first electric slider.

[0016] Furthermore, a second electric slide rail is fixedly connected to one end of the L-shaped support rod, a second electric slider is slidably connected inside the second electric slide rail, a hydraulic rod is fixedly connected to the bottom of the second electric slider, and a detection head is fixedly connected to the bottom end of the hydraulic rod.

[0017] The above scheme expands the range of forward and backward movement of the detection head by setting a second electric slide rail and a second electric slider.

[0018] Furthermore, a dual-axis motor is fixedly connected inside the adjustment box, a threaded rod is fixedly connected to the output end of the dual-axis motor, a threaded cylinder is threadedly connected to the surface of the threaded rod, and the movable rod is fixedly connected to the surface of the threaded cylinder.

[0019] The above solution, by setting up a dual-axis motor, can drive the threaded rod to rotate, thereby moving the threaded cylinder horizontally and automatically adjusting the position of the U-shaped plate, which can adapt to different sample sizes.

[0020] Furthermore, a handle is fixedly connected to the top of the protective cover.

[0021] The above solution, by setting handles, provides gripping points, making it easy to carry or move the protective cover.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This artificial leather surface hardness testing device features a protective cover. When not in use, the cover is placed on top of the base plate, and the locking strip engages between two limiting strips. Once engaged, the protective cover covers the testing area, preventing external interference or accidental touch by the operator, thus facilitating protection. The locking strip and limiting strips allow for quick installation and removal. To clamp the artificial leather, two knobs are rotated to rotate the rotating bolt, which, along with the push of the top block, moves the two lower pressure plates downwards, facilitating clamping and fixing. A rotating block and a level bubble are used to observe the level. By rotating multiple rotating blocks, the adjusting screw can rotate and move on the surface of the adjusting bolt, allowing for adjustment of the device's levelness. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Please see Figure 1 Figures 3 and 5 show the artificial leather surface hardness testing device in this embodiment, which includes a base plate 1 and a protective cover 2. The top of the base plate 1 is fixedly connected to a limiting strip 101, a first electric slide rail 102, an adjustment box 1011, and a controller 1010. The bottom of the protective cover 2 is fixedly connected to a snap-fit ​​strip 201. There are two limiting strips 101, and the snap-fit ​​strip 201 snaps between the two limiting strips 101. By setting the protective cover 2, when the device is not in use, people can place the protective cover 2 on the top of the base plate 1 and make the snap-fit ​​strip 201 snap between the two limiting strips 101. After snapping, the test area can be covered by the protective cover 2 to prevent external interference or accidental touch by the operator, thus making it easy for people to protect it.

A connecting spring 1019 is sleeved on the surface of the limiting rod 1017. The two ends of the connecting spring 1019 are fixedly connected to the top of the U-shaped plate 1016 and the top of the lower pressure plate 1018, respectively. When it is necessary to fix and clamp the artificial leather, people rotate the two knobs 1022 to rotate the rotating bolt 1021. By pushing the top block 1023, the two lower pressure plates 1018 can be moved down, which makes it easier for people to clamp and fix the artificial leather.

[0028] Please refer to Figures 2 and 4. A first electric slider 103 is slidably connected inside the first electric slide rail 102. An L-shaped support rod 104 is fixedly connected to the top of the first electric slider 103. By setting the first electric slide rail 102 and the first electric slider 103, the left and right movement range of the detection head 108 is expanded. A second electric slide rail 105 is fixedly connected to one end of the L-shaped support rod 104. A second electric slider 106 is slidably connected inside the second electric slide rail 105. A hydraulic rod 107 is fixedly connected to the bottom of the second electric slider 106. The detection head 108 is fixedly connected to the bottom end of the hydraulic rod 107. By setting a second electric slide rail 105 and a second electric slider 106, the range of forward and backward movement of the detection head 108 is expanded. A dual-axis motor 1012 is fixedly connected inside the adjustment box 1011. A threaded rod 1013 is fixedly connected to the output end of the dual-axis motor 1012. A threaded cylinder 1014 is threadedly connected to the surface of the threaded rod 1013. A movable rod 1015 is fixedly connected to the surface of the threaded cylinder 1014. By setting the dual-axis motor 1012, the threaded rod 1013 can be driven to rotate, which drives the threaded cylinder 1014 to move horizontally and automatically adjust the position of the U-shaped plate 1016 to adapt to different sample sizes.

[0029] Please refer to Figure 2. A handle 202 is fixedly connected to the top of the protective cover 2. By setting the handle 202, a gripping point can be provided to facilitate the handling or movement of the protective cover 2.

[0030] In this embodiment, by setting a protective cover 2, when the device is not in use, the protective cover 2 is placed on top of the base plate 1, and the snap-fit ​​strip 201 is snapped between the two limit strips 101. After the snap-fit ​​is completed, the test area can be covered by the protective cover 2 to prevent external interference or accidental touch by the operator, thus facilitating protection. Through the cooperation of the snap-fit ​​strip 201 and the limit strip 101, the protective cover 2 can be quickly installed or removed. By setting a rotating block 1027 and a level bubble 1024, people can observe the level bubble 1024, and then rotate multiple rotating blocks 1027 respectively, so that the adjusting screw 1026 can rotate and move on the surface of the adjusting bolt 1025, thereby adjusting the levelness of the device.

[0031] The working principle of the above embodiment is as follows: When in use, people place the device in a suitable position, and then observe the level bubble 1024, rotate multiple rotating blocks 1027 respectively, so that the adjusting screw 1026 can rotate and move on the surface of the adjusting bolt 1025 to adjust the levelness of the device. After the adjustment is completed, the device can be used. When testing artificial leather, it is placed between two U-shaped plates 1016. After placement, two knobs 1022 are rotated to rotate the rotating bolt 1021. The push of the top block 1023 causes the two lower pressure plates 1018 to move down, clamping and fixing the artificial leather. After fixing, the dual-axis motor 1012 runs, causing the threaded rod 1013 to rotate, which drives the threaded cylinder 1014 to move on the surface of the threaded rod 1013. This moves the two U-shaped plates 1016 outward, allowing the artificial leather to unfold. After unfolding, the first electric slide rail 102 and the second electric slide rail 105 run to adjust the position of the detection head 108. After adjustment, the hydraulic rod 107 runs, pushing the detection head 108 down, thus allowing the hardness of the artificial leather surface to be tested.
