Technical Field

[0001] This utility model relates to the field of paperboard testing technology, and in particular to an environmentally friendly paperboard strength testing device. Background Technology

[0002] Environmentally friendly paperboard is made from easily biodegradable materials, reducing environmental pollution and waste generated during its production. It is widely used in the manufacture of packaging boxes, gift boxes, and product packaging. Its overall durability and sturdiness make it suitable as a protective packaging structure during product transportation. Before being put into use, environmentally friendly paperboard undergoes strength testing. Various equipment and methods exist for strength testing to ensure the quality of environmentally friendly paperboard and reduce the use of inferior products. Compression and puncture resistance tests are typically conducted separately on specially designed testing equipment.

[0003] However, the puncture strength test and compressive strength test of common environmentally friendly paperboard are mostly carried out separately. Since the separate operation increases the number of testing steps, prolongs the testing time, and reduces the testing efficiency, we propose an environmentally friendly paperboard strength testing device.

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an environmentally friendly cardboard strength testing device.

A punching needle module is installed on the bottom wall of the protective cover. A pressure application component is arranged below the protective cover.

[0006] Preferably, the first movable plate and the second movable plate are respectively provided with a first sliding hole and a second sliding hole, and the top ends of the plurality of support rods respectively pass through the first sliding hole and the second sliding hole corresponding to the position and are connected to the bottom wall of the top plate.

[0007] Preferably, the second movable plate has rotating holes, and bearings are arranged in each of the rotating holes. The top ends of the multiple first rotating shafts and second rotating shafts are respectively inserted into the bearings at corresponding positions.

[0008] Preferably, a forward and reverse motor is arranged at the top of the first rotating shaft. The forward and reverse motor is mounted on the top wall of the second movable plate.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This invention utilizes a hydraulic cylinder to drive the first and second movable plates, connected by springs, to adjust the height of the pressure application and switching components inside the protective cover and at the bottom. The sample environmentally friendly cardboard, placed on the testing area of ​​the operating table, is then compressed by a pressure mold, achieving automatic detection of the cardboard's compressive strength. Simultaneously, driven by forward and reverse motors, three first rotating shafts, assisted by a second rotating shaft, engage with three first gears via a second gear to adjust the rotation of the locking component. This removes the overall restriction on the pressure application component, facilitating disassembly and replacement. Furthermore, during the compression testing process, the puncture needle module continuously descends to complete the puncture detection of the cardboard. The pressure application component can be disassembled, replaced, and maintained according to its condition. The integrated compression and puncture detection reduces the space occupied by two different functional testing devices. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example

[0020] like Figures 1 to 3 As shown, this utility model proposes an environmentally friendly cardboard strength testing device, including an operating table 1, an operating panel 2 fixedly installed on the top wall of the operating platform of the operating table 1 for easy operation by the operator; the bottom ends of multiple support rods 3 are fixedly connected to the top wall of the testing platform of the operating table 1, and the top ends of the multiple support rods 3 respectively pass through the spring 10 and the second sliding hole and the first sliding hole opened on the first movable plate 5, and are fixedly connected to the bottom wall of the top plate 11, providing support for the hydraulic cylinder 4 installed on the top of the top plate 11; a third sliding hole is opened on the top wall of the top plate 11, and the output end of the hydraulic cylinder 4 passes through the third sliding hole opened on the top plate 11 and is connected to the top wall of the first movable plate 5. The fixed connection allows the first movable plate 5 to be vertically raised and lowered in cooperation with the first sliding hole and the support rod 3. The pressure sensor 12 is fixedly installed on the bottom wall of the first movable plate 5, which is beneficial for detecting the puncture and compressive strength of the cardboard during the subsequent descent. Multiple springs 10 are sleeved on the support rod 3 at the corresponding positions and are set between the opposing walls of the first movable plate 5 and the second movable plate 9, so that the top end of the spring 10 is connected to the bottom wall of the first movable plate 5 and the bottom end is connected to the top wall of the second movable plate 9. This helps to maintain a gap between the opposing walls of the first movable plate 5 and the second movable plate 9, which facilitates the separate operation of the cardboard's subsequent compressive strength and puncture.

[0021] Furthermore, the top opening of the protective cover 6 is fixedly connected to the bottom wall of the second movable plate 9. The switching assembly 8 is installed on the second movable plate 9 and the protective cover 6. The switching assembly 8 includes a forward / reverse motor 81, a first rotating shaft 82, a first gear 83, a second gear 84, a second rotating shaft 85, a square rod 86, a locking piece 87, and a reinforcing rib 88. The top ends of the three first rotating shafts 82 and the second rotating shafts 85 are inserted into the rotating holes opened on the second movable plate 9. The bearings arranged in the multiple rotating holes are sleeved on the outer surface wall of the first rotating shafts 82 and the second rotating shafts 85 at corresponding positions, which play a role in positioning and assisting the rotation of the first rotating shafts 82 and the second rotating shafts 85. Gear 83 is sleeved on the outer surface wall of the first rotating shaft 82 at the corresponding position, and second gear 84 is sleeved on the outer surface wall of the second rotating shaft 85. The second gear 84 meshes with the first gear 83 to play a transmission role. The forward and reverse motor 81 is fixedly installed on the top wall of the second movable plate 9, and its output end is connected to the top of one of the first rotating shafts 82, so that the forward and reverse motor 81 can drive one of the first rotating shafts 82 to drive the other first rotating shafts 82 to rotate in conjunction with the transmission of the second gear 84 and the first gear 83. A sliding opening is provided on the first movable plate 5, and part of the structure of the forward and reverse motor 81 is set into the sliding opening to prevent it from affecting the subsequent descent to perform compression resistance testing on the environmentally friendly cardboard.

[0022] Furthermore, the puncture needle module 13 is fixedly installed on the bottom wall of the protective cover 6 for puncture detection of environmentally friendly cardboard. The pressure application component 7 is arranged below the protective cover 6. The pressure application component 7 includes a pressure mold 71 and vertical shafts 72. The bottom ends of multiple vertical shafts 72 are fixedly connected to the top wall of the pressure mold 71. A fourth sliding hole is opened on the bottom wall of the protective cover 6. The top ends of multiple vertical shafts 72 pass through the corresponding fourth sliding hole and are set into the protective cover 6. The top ends of three square rods 86 are respectively inserted into the square grooves opened in the first rotating shaft 82. Multiple locking parts 87 are welded to... On the outer wall of the square rod 86 corresponding to the position, the vertical and horizontal structures of multiple reinforcing ribs 88 are welded to the corresponding locking parts 87 and the outer wall of the square rod 86, respectively, which reinforces the right angle of the connection between the square rod 86 and the locking parts 87; the outer surface of multiple vertical shafts 72 is provided with slots, and part of the structure of multiple locking parts 87 is inserted into the corresponding slots, which limits the overall pressure application component 7, making it easier to drive the pressure application component 7 to rise and fall, and the square rod 86 and the square slots prevent the subsequent lifting, compression resistance and puncture detection of the cardboard from being affected.

[0023] Furthermore, part of the structure of the stamping needle module 13 is set in a groove on the top wall of the mold 71, which is conducive to lifting and lowering under the guidance of the groove. The stamping needle head of the stamping needle module 13 is inserted into the needle hole on the bottom wall of the groove, which is convenient for subsequent puncture detection of the cardboard. A hidden groove is provided on the inner surface wall of the mold 71, and a laser positioning sensor 14 is installed in the hidden groove. The laser positioning sensor 14 is used to detect the lifting and lowering position of the stamping needle module 13, which is convenient for subsequent positioning and release operation of the pressure application component 7.

[0024] In this embodiment, the hydraulic cylinder 4 is activated to push the first movable plate 5 downward, causing the protective cover 6 and the second movable plate 9 to follow the first movable plate 5 downward under the connection of the spring 10. The pressure mold 71 then performs a compression test on the cardboard placed on the detection platform of the operating table 1. When a puncture test is required, the forward and reverse motors 81 are activated to drive a first rotating shaft 82 to rotate. This causes all three first rotating shafts 82 and the first gear 83 to rotate simultaneously under the transmission of the second gear 84, disengaging the locking member 87 from the slot and releasing the restriction on the vertical shaft 72. This facilitates the continuous descent of the puncture needle module 13 via the hydraulic cylinder 4. The square slot and square rod 86 cooperate to avoid affecting the descent of the puncture needle module 13 on the cardboard. The device performs puncture testing, achieving the integration of cardboard compression resistance and puncture testing. This reduces the procurement cost and space occupation of two different functional devices. By removing the restriction on the vertical shaft 72, the entire pressure application component 7 can be disassembled, making it convenient for staff to disassemble, replace, or maintain the component according to its overall usage. This facilitates subsequent maintenance of the testing structure. During installation, simply insert the vertical shaft 72 into the fourth sliding hole on the bottom wall of the protective cover 6. After detection by the laser positioning sensor 14, when the slot and the positioning piece 87 are aligned, the forward and reverse motor 81 drives a first rotating shaft 82 to reverse, causing the positioning piece 87 to re-engage into the slot, thus completing the automatic installation of the entire pressure application component 7. This method is simple and easy to operate.

[0025] The above specific embodiments are merely several preferred embodiments of this utility model.
