Description

Technical Field

[0002] Corrugated paper is a sheet material made by gluing together corrugated sheets of paper formed by processing liner paper and corrugating rollers. It is generally divided into two categories: single-corrugated and double-corrugated. Based on the flute size, it is classified into five types: A, B, C, E, and F. A handheld corrugated paper thickness tester is a tool specifically designed for measuring the thickness of corrugated paper. Its main function is to quickly and accurately obtain thickness data for corrugated paper quality assessment and control. This device has important applications in all aspects of corrugated paper production, processing, and sales.

[0003] However, most existing handheld corrugated paper thickness measuring devices encounter wrinkles in the corrugated paper during use, making it difficult for the measuring head to maintain uniform contact with the corrugated paper, resulting in deviations in the measured thickness data.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figures 1 to 3 , the utility model provides an embodiment: a handheld corrugated paper thickness testing device, including a handheld handle 1. By opening a cavity inside the handheld handle 1 and opening an arc-shaped shape and size, it is convenient for the user to hold, and the user can remain comfortable during long-term operation. The top of the handheld handle 1 is fixedly connected to a test display shell 2, which is used to display and detect the thickness of the corrugated paper. The inside of the test display shell 2 is slidably connected to a sliding rod 3, and the sliding rod 3 is restricted and guided by the test display shell 2, so that the sliding rod 3 can slide vertically up and down. The outside of the sliding rod 3 is slidably connected to the inner wall of the left end of the handheld handle 1 to ensure that the sliding rod 3 does not shake or deflect when sliding, thereby ensuring the accuracy of the measurement. The front and rear sides of the handheld handle 1 are fixedly connected to the side frame 4, and the handheld handle 1 and the side frame 4 are fixed by welding, so as to provide an installation and support platform for subsequent components;

[0034] The bottom side of the sliding rod 3 is fixedly connected to an upper detection head 5. The circular design of the upper detection head 5 ensures that pressure is evenly distributed across the corrugated paper surface during measurement. Side panels 6 are fixedly connected to the left and right ends of the upper detection head 5. When the sliding rod 3 pushes the upper detection head 5, the sliding force is transmitted to the side panels 6, enabling the side panels 6 to slide up and down. A fixing rod 7 is fixedly connected to the top side of the side panels 6, transmitting the sliding force to the fixing rod 7 through the side panels 6, enabling the fixing rod 7 to slide. A limit plate 8 is fixedly connected to the top side of the fixing rod 7, which provides support for the fixing rod 7 and prevents it from slipping. The exterior of both limit plates 8 are slidably connected to the inner wall of the left end of the handle 1, ensuring that the limit plates 8 can move smoothly and be effectively restrained during sliding, preventing them from falling off track. A spring 9 is sleeved on the exterior of the fixing rod 7, which constrains the spring 9 to ensure uniform force. The bottom side of the limit plate 8 is fixedly connected to the top of the spring 1 9. The spring 1 9 can store elastic potential energy after being squeezed, and then give the limit plate 8 a restoring force to rebound.

[0035] The front and rear ends of the top side of the upper detection head 5 are fixedly connected with an opening block 10. The upper detection head 5 can transmit the sliding force to the opening block 10 during the sliding process, so that the opening block 10 can slide up and down. The internal rotation of the opening block 10 is connected to the rotating plate 11. The rotational connection between the opening block 10 and the rotating plate 11 enables the opening block 10 to push the rotating plate 11 to rotate around the opening block 10 as the center during the sliding process. The bottom end of the rotating plate 11 is fixedly connected to the limiting rod 12, and the limiting rod 12 can be driven to slide by the rotating plate 11 during the displacement process. The external sliding connection of the limiting rod 12 is connected to the inner wall of the side frame 4. The limiting rod 12 can slide along the inside of the side frame 4 through the restriction and guidance of the side frame 4. The external rotation connection of the limiting rod 12 is connected to the concave block 13, and the limiting rod 12 is driven to slide by the concave block 13. The bottom side of the concave block 13 is fixedly connected with a flattening plate 14. When the flattening plate 14 contacts the corrugated paper, it pushes the flattening plate 14 to expand through friction and pushing, thereby avoiding wrinkle detection.

[0036] The right end of the test display shell 2 is fixedly connected to a pressing assembly that presses the sliding rod 3 to slide. The bottom end of the handheld handle 1 is fixedly connected to a lower detection head 16. The position of the lower detection head 16 corresponds to the upper detection head 5. During measurement, it works together with the upper detection head 5 to clamp the corrugated paper for thickness measurement. The outside of the lower detection head 16 is fixedly connected to a placement plate 15 to provide a clamping support force for the corrugated paper. A right-angle opening 17 is provided inside the side frame 4 to provide guidance and restriction for the limit rod 12, so that the limit rod 12 can first slide vertically in the horizontal sliding direction, and vice versa. The pressing assembly includes a concave frame 18, the bottom side of the concave frame 18 is fixedly connected to the right end of the test display shell 2, and is fixed between the concave frame 18 and the test display shell 2 through a welding process, so that it can provide support and restriction for subsequent components. A pressing plate 19 is rotatably connected to the interior of the concave frame 18. Restricted by the concave frame 18, the pressing plate 19 can rotate about the concave frame 18. An I-shaped column 20 is fixedly connected to the top side of the sliding rod 3. The I-shaped column 20 applies force, driving the sliding rod 3 up and down. The left end of the pressing plate 19 engages the exterior of the I-shaped column 20, and the rotation of the I-shaped column 20 drives the engaging pressing plate 19 up and down.

[0037] Reference Figures 4 to 6, the rear end of the test display shell 2 is slidably connected to a cover plate 21, which can prevent dust and other impurities from entering the interior of the test display shell 2 and affecting the normal operation of the internal components. The upper and lower sides of the cover plate 21 are fixedly connected to the limit blocks 22, and the outer parts of the two limit blocks 22 are respectively slidably connected to the upper and lower inner walls of the test display shell 2. Through the guidance of the limit blocks 22, the cover plate 21 can be driven to slide to the interior of the test display shell 2 for engagement. The rear side of the cover plate 21 is fixedly connected to a handle 23, which is convenient for the user to hold the handle 23 to drive the cover plate 21 to slide, providing convenience. The left and right ends of the cover plate 21 are slidably connected to sliding blocks 24, which are restricted by the cover plate 21 so that the sliding blocks 24 can slide horizontally left and right;

[0038] A sliding plate 25 is fixedly connected to the front side of the sliding block 24. Pressing the sliding block 24 causes the sliding plate 25 to slide, which in turn causes the sliding plate 25 to slide. Trapezoidal openings are provided on both ends of the cover 21. The distal ends of the two sliding plates 25 are slidably connected to the left and right inner walls of the test display housing 2. The sliding plates 25 engage the interior of the test display housing 2 to facilitate assembly and disassembly of the cover 21. The exterior ends of the two sliding plates 25 are slidably connected to the left and right inner walls of the cover 21, respectively. The cover 21 restricts and guides the sliding plates 25, allowing them to slide horizontally left and right. A second spring 26 is fixedly connected to the adjacent side of each sliding plate 25. When pressurized, the spring 26 stores elastic potential energy, which in turn applies a force in the opposite direction to reset the sliding plate 25. The adjacent ends of the two springs 26 are fixedly connected to the left and right inner walls of the cover 21. By securing the springs 26, the springs 26 are evenly loaded.

[0039] Working principle: First, by pressing the pressing plate 19 to rotate around the concave frame 18, the I-shaped column 20 is pushed upward, and then the sliding rod 3 is pushed upward, and the upper detection head 5 is driven to slide upward by the sliding rod 3, and then the corrugated paper is placed on the top side of the placement plate 15. At the same time, the upper detection head 5 will also drive the side plate 6 to slide upward, thereby driving the limit plate 8 to slide upward and stretch the spring 19, so that the spring 19 can store elastic potential energy, and then give the limit plate 8 a reverse force to reset, thereby pushing the fixed rod 7 to reset, and then pushing the side plate 6 to reset. At this time, the upper detection head 5 can be pushed downward and against the corrugated paper, and the sliding rod 3 is driven to reset and slide downward by the upper detection head 5, thereby driving the opening block 10 to slide downward, and at the same time, the side The right-angle opening 17 opened inside the frame 4 allows the limiting rod 12 to reset downward from the top, and then reset horizontally. The limiting rod 12 is used to limit and guide the opening block 10, so that the rotating plate 11 and the limiting rod 12 can slide downward. After the limiting rod 12 reaches the bottom, the flattening plate 14 is used to press against the corrugated paper due to its flexibility and friction. Then the limiting rod 12 will slide horizontally, and then the two limiting rods 12 will slide to the far side, and then drive the concave block 13 to slide, thereby driving the flattening plate 14 to slide and achieve the effect of unfolding the corrugated paper. Then, after the sliding rod 3 drives the upper detection head 5 to reset to contact with the corrugated paper, it cooperates with the lower detection head 16 to transmit the measurement results to the test display housing 2 for displaying the measurement results.

[0040] When the test display housing 2 needs to be repaired, the sliding block 24 is held and a thrust is applied, thereby driving the sliding plate 25 to slide and squeeze the spring 26, so that the spring 26 can store elastic potential energy, thereby giving the sliding plate 25 a reset force. After the sliding plate 25 slides out of the interior of the test display housing 2, the handle 23 can be held and the cover 21 can be removed, which facilitates the maintenance of the interior of the test display housing 2, thereby improving the maintenance efficiency.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
