Description

Technical Field

[0001] The utility model relates to the technical field of EPDM sheet production, in particular to a device for detecting the thickness of an EPDM sheet. Background Art

[0002] EPDM (Ethylene Propylene Diene Monomer) is a copolymer of ethylene, propylene, and a small amount of non-conjugated dienes. It is a type of ethylene propylene rubber and is represented by EPDM (Ethylene Propylene Diene Monomer). Because its main chain is composed of chemically stable saturated hydrocarbons and contains unsaturated double bonds only in the side chains, it has excellent aging resistance such as ozone resistance, heat resistance, and weather resistance. It can be widely used in automotive parts, building waterproofing materials, wire and cable sheathing, heat-resistant hoses, tapes, automotive seals and other fields.

[0003] The EPDM sheet thickness detection device in the prior art is usually fixed in actual use and is not convenient to move according to the use requirements. When the EPDM sheet needs to be tested, the part to be tested can only be placed under the sensor for testing, which is not convenient for rapid multi-point detection, resulting in inconvenience in use. Therefore, we propose an EPDM sheet thickness detection device to solve the above-mentioned problems. Utility Model Content

The control rod 8 is rotatably connected to the left side of the control panel 7, and the unlocking plate 10 is rotatably connected to the right side of the control rod 8. The rear side of the unlocking plate 10 is fixedly connected to the front side of the positioning block 11. The movement of the control panel 7 will push the control rod 8, and the movement of the control rod 8 will push the unlocking plate 10 forward. When the unlocking plate 10 moves, it will drive the positioning block 11 to move forward and disengage from the positioning groove, thereby unlocking the movable sleeve 3 and the connecting frame 4, making it convenient to move the laser thickness sensor 5.

[0034] As a preferred solution of the present invention, the front side of the movable sleeve 3 located on the front side is fixedly connected to a support frame 9, the inner wall of the support frame 9 is slidably connected to the outer wall of the unlocking plate 10, and the top of the support frame 9 is fixedly connected to the bottom of the handle 6.

The elastic force of the reset spring 12 facilitates the upward movement and reset of the control board 7.

[0037] As a preferred solution of the present invention, the front side of the control panel 7 is fixedly connected to the limiting block, and the rear side of the handle 6 is provided with a limiting groove. The inner wall of the limiting groove is slidably connected to the outer wall of the limiting block.

[0038] It should be noted that the specific type of laser thickness sensor 5 to be used is a matter for those skilled in the art to select, and the above laser thickness sensor 5 and the like are all existing technologies and will not be elaborated in this solution.

[0039] The working principle of the present invention is as follows: in actual use, when the thickness of the EPDM sheet needs to be tested, the EPDM sheet to be tested is placed on the top of the base 1. When measurement is required, a plurality of positioning slots are first opened on the front side of the positioning frame 2 located on the front side according to the use requirements. At this time, the handle 6 is held and the control plate 7 is pushed downward. The downward movement of the control plate 7 will compress the reset spring 12. At the same time, the movement of the control plate 7 will push the control rod 8. The movement of the control rod 8 will push the unlocking plate 10 forward. When the unlocking plate 10 moves, the positioning spring 13 is compressed. At the same time, the unlocking plate 10 will drive the positioning block 11 to move forward and disengage from the positioning slot, thereby unlocking the movable sleeve 3 and the connecting frame 4. At this time, the connecting frame 4 can be pushed to move horizontally and bring The laser thickness sensor 5 moves laterally, and the connecting frame 4 moves, which will drive the movable sleeve 3 to slide. The positioning frame 2 is used to limit the movable sleeve 3 so that the connecting frame 4 can move laterally stably. When the laser thickness sensor 5 moves to a suitable position, the control plate 7 is released. At this time, the reset spring 12 loses its limit and pushes the control plate 7 up and pulls the control rod 8 to reset. At this time, the positioning spring 13 loses its limit and pushes the unlocking plate 10 to move backward. The reset of the unlocking plate 10 will drive the positioning block 11 to move backward. The reset of the positioning block 11 will engage with the positioning groove to fix the connecting frame 4, thereby fixing the laser thickness sensor 5 at the current position. At this time, the laser thickness sensor 5 is started, and the thickness of the EPDM sheet is detected by the laser thickness sensor 5.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
