Description

Technical Field

[0001] This invention relates to the field of comprehensive performance testing technology for paperboard, specifically a comprehensive performance testing device for the production of moisture-proof and high-temperature resistant special paperboard. Background Technology

[0002] In the production and application of specialty paperboard, moisture resistance and high-temperature resistance are key indicators of its quality. Due to their excellent performance characteristics, these paperboards are widely used in fields with stringent requirements for packaging materials, such as electronic components, precision instruments, food preservation, and pharmaceutical packaging. Especially in harsh environments with high temperature and humidity, large temperature variations, or long-term storage and transportation, the performance stability of specialty paperboard directly affects not only the protective effect of the packaged goods but also the shelf life and safety of the products. However, current industry testing technologies have significant limitations, making it difficult to comprehensively and accurately evaluate the overall performance of specialty paperboard. Traditional testing equipment often adopts a single-function design, such as independent... Compression testers can only measure the compressive strength of paperboard, bursting strength testers can only assess puncture resistance, and moisture resistance testing requires a dedicated humidity environment simulation device. This decentralized testing model forces companies to configure multiple specialized devices in the quality control process, which not only occupies a lot of production space but also makes the testing process lengthy and complicated, seriously affecting production efficiency. More importantly, special paperboard often needs to withstand multiple composite stresses in actual use. For example, it must maintain structural strength and moisture resistance in high-temperature environments. The itemized testing method cannot simulate such complex working conditions, resulting in a significant deviation between test results and actual application performance.

[0003] For example, the "Comprehensive Testing Device for Cardboard Box Performance" disclosed in Chinese Invention Patent (Application No.: CN202411653877.0) states in its specification that cardboard boxes are important industrial products used for packaging, protecting, and transporting goods. The quality of cardboard boxes directly affects the stability of packaged goods and the safety and efficiency of transportation. To ensure that cardboard box products meet relevant standards and customer needs, and to guarantee product safety and stability, various forms of inspection are required. Existing technologies for inspecting cardboard boxes mainly include compressive strength testing, tensile strength testing, bursting strength testing, and thickness testing. Among these, the most common tests are compressive strength testing and bursting strength testing. Bursting strength testing assesses the cardboard box's ability to resist puncture by external forces, ensuring that the cardboard box can withstand localized compression in actual transportation environments. Compressive strength testing assesses the maximum pressure the cardboard box can withstand, ensuring that it will not deform or break during stacking and transportation. Existing cardboard and paperboard testing devices can generally only perform one of multiple tests; to achieve multiple tests for cardboard and paperboard, different testing devices are required; the aforementioned patents can corroborate the shortcomings of existing technologies. Therefore, we propose a comprehensive performance testing device for the production of moisture-proof and high-temperature resistant special paperboard. Summary of the Invention

[0004] The purpose of this invention is to provide a comprehensive performance testing device for the production of moisture-proof and high-temperature resistant special paperboard, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a comprehensive performance testing device for the production of moisture-proof and high-temperature resistant special paperboard, comprising a fixed base and a sliding base spaced apart on one side of the fixed base. The top of the fixed base and the sliding base are symmetrically distributed with clamping components that perform paperboard performance testing by compression. The fixed base and the sliding base are connected by a sliding component. The sliding base is n-shaped and is mounted on top of the sliding component.

[0006] Preferably, the sliding assembly includes a first slide rail mounted on the side of the fixed base near the sliding base, a first slider slidably sleeved on the top of the first slide rail, the top of the first slider being fixedly connected to the bottom of the sliding base, a servo motor mounted on the side of the top of the first slide rail away from the fixed base, a lead screw being pre-set at the output end of the servo motor, and the first slider being threadedly connected to the lead screw.

[0007] Preferably, the clamping assembly includes a support side plate installed at the top center of the fixed seat and the sliding seat. Each of the two sets of support side plates is provided with a mounting side plate on the side that is close to each other. A connecting shaft extends from one side of the mounting side plate. The mounting side plate is rotatably sleeved with the support side plate through the connecting shaft. The middle part of the side that is close to each other of the two sets of mounting side plates is connected to the second slide rail.

[0008] Preferably, a second slider is symmetrically sleeved on the outer side of the second slide rail. A right-angle plate is pre-set on the outer side of the second slider, and a square plate is symmetrically pre-set on the bottom of the right-angle plate. The square plate is fixedly connected to the bottom of the second slider. Threaded rods are spaced apart on the inner side of the mounting side plate. Both sets of second sliders are threadedly connected to the threaded rods. Knobs are fixedly installed at both ends of the threaded rods. The middle part of the threaded rod is a round rod, and threaded grooves with opposite thread directions are symmetrically distributed on both sides. The two sets of second sliders are respectively threadedly connected to the two sets of threaded grooves.

[0009] Preferably, gears are spaced apart on the outer side of the second slider, and a drive motor is fixedly mounted on the top of the gears. The output end of the drive motor is fixedly connected to the output end of the gears. The gears are located on the inner side of the right-angle plate, and the drive motor is mounted on the top of the right-angle plate.

[0010] Preferably, a rack meshes with the outer side of the gear, the rack is located between the gear and the second slider, a downwardly extending limiting block is installed on the outer side of the rack, and a sliding rod extending to both ends is sleeved in the middle of the limiting block. The second slider is located between the two sets of square plates, and the square plates are sleeved with the sliding rods. The drive motor drives the rack meshing with it through the gear.

[0011] Preferably, the inner side of the slide rod is fitted with a rotating shaft extending to both ends, the outer side of the rotating shaft is pre-threaded, the rotating shaft meshes with the teeth on the inner side of the slide rod, and both ends of the rotating shaft are fixedly installed with pads.

[0012] Preferably, a clamping plate is fixedly installed at one end of the rack, and side holes extending inward are evenly opened on one side of the clamping plate. A movable plate is sleeved in the middle of the inner cavity of the clamping plate, and conical needles are evenly distributed on the side of the movable plate near the side holes.

[0013] Preferably, a spring sheet is arrayed on the other side of the movable plate, and the outer side of the spring sheet is connected to the inner cavity of the clamping plate. A push rod is fixedly installed on the outer side of the movable plate. The push rod passes through the side wall of the clamping plate and is fixedly connected to a set of pads. The clamping plate is sleeved with the push rod.

[0014] Preferably, telescopic cylinders are symmetrically installed on the top of both the fixed seat and the sliding seat, and pull ropes are symmetrically installed on the outer sides of both sets of mounting side plates, with the bottom of the pull ropes fixedly connected to the top of the telescopic cylinders.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In terms of compression resistance test, the servo motor drives the lead screw to move the sliding seat smoothly along the first slide rail, so that the two sets of symmetrically distributed clamping components apply uniform pressure to the cardboard. The combination of the first slide rail and the first slider ensures the stability of the force application process.

[0016] 2. The bursting strength test function can be achieved by evenly distributed conical needles. After the clamping plate holds and fixes the cardboard through the gear and rack mechanism, the drive motor drives the gear to rotate, so that the rack pushes the clamping plate to complete the initial fixation. At this time, the rotating shaft generates axial displacement under the thread meshing action on the inner side of the slide rod. The push rod pushes the movable plate, so that the conical needle extends out of the side hole. The elastic design of the spring not only ensures the stable puncture of the conical needle, but also enables it to automatically reset after the test.

[0017] 3. Tear performance testing is achieved through a telescopic cylinder and a pull rope. When a tear test is required, the control system activates the telescopic cylinder, which pulls the mounting side plate to produce a controllable tilt angle through the pull rope. Since the mounting side plates on both sides are rotatably connected to the supporting side plate through the connecting shaft, they can achieve tilting movements in opposite directions, thereby applying tearing force to the cardboard. At the same time, combined with compression resistance and bursting performance testing, they can be carried out simultaneously, which not only improves the testing efficiency, but more importantly, simulates the complex stress state of cardboard during actual transportation and storage.

[0018] 4. The bidirectional threaded design of the threaded rod allows operators to simultaneously adjust the distance between the two second sliders by rotating the knob, quickly adapting to samples of different thicknesses; the combination of the second slide rail and the second slider ensures the accuracy of the clamping position, while the gear and rack transmission realizes stepless adjustment of the clamping force; thus meeting various testing needs from thin single-layer to thick multi-layer cardboard.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1 - Figure 7 As shown, the present invention provides a technical solution: a comprehensive performance testing device for the production of moisture-proof and high-temperature resistant special paperboard, including a fixed base 1 and a sliding base 2 spaced apart on one side of the fixed base 1. The tops of the fixed base 1 and the sliding base 2 are symmetrically distributed with clamping components that achieve paperboard performance testing by compression. The fixed base 1 and the sliding base 2 are connected by a sliding component. The sliding base 2 is n-shaped and is mounted on the top of the sliding component. The sliding component drives the sliding base 2 to approach the fixed base 1, thereby achieving performance testing by compressing the paperboard.

[0023] In the preferred embodiment of this technical solution, please refer to Figure 1 and Figure 2 As shown, the sliding assembly includes a first slide rail 3 installed on the side of the fixed base 1 near the sliding base 2.

A servo motor 5 is installed on the side of the top of the first slide rail 3 away from the fixed base 1. A lead screw is preset at the output end of the servo motor 5. The first slider 4 is threadedly connected to the lead screw. The servo motor 5, in conjunction with the lead screw installed at its output end, facilitates the sliding of the first slider 4 on the top of the first slide rail 3, thereby causing the sliding base 2 connected to the first slide rail 3 to continuously slide towards the fixed base 1.

[0024] In the preferred embodiment of this technical solution, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the clamping assembly includes a support side plate 6 installed at the top center of the fixed base 1 and the sliding base 2. Each of the two sets of support side plates 6 is provided with a mounting side plate 7 on the side that is close to each other. A connecting shaft extends from one side of the mounting side plate 7. The mounting side plate 7 is rotatably sleeved with the support side plate 6 through the connecting shaft. The middle part of the side that is close to each other of the two sets of mounting side plates 7 is connected to the second slide rail 10.

[0025] Furthermore, a second slider 11 is symmetrically sleeved on the outer side of the second slide rail 10. A right-angle plate is pre-set on the outer side of the second slider 11, and a square plate is pre-set symmetrically on the bottom of the right-angle plate. The square plate is fixedly connected to the bottom of the second slider 11. Threaded rods 25 are spaced apart on the inner side of the mounting side plate 7. Both sets of second sliders 11 are threadedly connected to the threaded rods 25. Knobs are fixedly installed at both ends of the threaded rods 25. The middle part of the threaded rods 25 is a round rod, and threaded grooves with opposite thread directions are symmetrically distributed on both sides. The two sets of second sliders 11 are threadedly connected to the two sets of threaded grooves respectively. By rotating the threaded rods 25, the two sets of second sliders 11 threadedly connected to it are brought closer to each other, thereby roughly adjusting the gap between the two sets of second sliders 11 to adapt to cardboard of different thicknesses.

[0026] Furthermore, gears 23 are spaced apart on the outer side of the second slider 11, and a drive motor 24 is fixedly mounted on the top of the gears 23. The output end of the drive motor 24 is fixedly connected to the output end of the gears 23. The gears 23 are located on the inner side of the right-angle plate, and the drive motor 24 is mounted on the top of the right-angle plate.

[0027] Furthermore, a rack 14 meshes with the outer side of the gear 23. The rack 14 is located between the gear 23 and the second slider 11. A downwardly extending limiting block 12 is installed on the outer side of the rack 14, and a sliding rod 13 extending to both ends is sleeved in the middle of the limiting block 12. The second slider 11 is located between two sets of square plates, and the square plates are sleeved with the sliding rod 13. The drive motor 24 drives the rack 14 meshing with it through the gear 23.

[0028] Furthermore, a rotating shaft 16 extending to both ends is sleeved on the inner side of the slide rod 13. The outer side of the rotating shaft 16 has a pre-set threaded groove. The rotating shaft 16 meshes with the teeth on the inner side of the slide rod 13. Both ends of the rotating shaft 16 are fixedly installed with pads 17. By rotating the rotating shaft 16, it slides while meshing with the inner side of the slide rod 13.

[0029] In the preferred embodiment of this technical solution, please refer to Figure 7 As shown, a clamping plate 15 is fixedly installed at one end of the rack 14. Side holes 19 extending inward are evenly opened on one side of the clamping plate 15. A movable plate 20 is sleeved in the middle of the inner cavity of the clamping plate 15, and conical needles 21 are evenly distributed on the side of the movable plate 20 near the side hole 19.

[0030] Furthermore, spring pieces 22 are arrayed on the other side of the movable plate 20, and the outer side of the spring pieces 22 is connected to the inner cavity of the clamping plate 15. The spring pieces 22 facilitate the reset of the movable plate 20 after it has moved. A push rod 18 is fixedly installed on the outer side of the movable plate 20. The push rod 18 passes through the side wall of the clamping plate 15 and is fixedly connected to a set of pads 17. The clamping plate 15 is sleeved with the push rod 18. The rack 14 slides continuously under the drive of the gear 23, thereby causing the clamping plate 15 to slide continuously. Thus, the two sets of clamping plates 15 are combined to clamp one side of the cardboard. Then, with the help of the other two sets of clamping plates 15, the two sides of the cardboard can be clamped. By rotating the rotating shaft 16, it pushes a set of pads 17 and push rod 18 to move, pushing the movable plate 20, causing the conical needle 21 to pass through the side hole 19 and extend to its outer side, thereby cooperating with the clamping to realize the puncture test of the cardboard.

[0031] Furthermore, telescopic cylinders 8 are symmetrically installed on the top of both the fixed base 1 and the sliding base 2, and pull ropes 9 are symmetrically installed on the outer sides of both sets of mounting side plates 7. The bottom of the pull ropes 9 is fixedly connected to the top of the telescopic cylinders 8. When the two sides of the cardboard are clamped by the two sets of corresponding clamping plates 15, the telescopic length of the telescopic cylinders 8 is adjusted accordingly to cooperate with the pull ropes 9 and drive the mounting side plates 7 connected to them to tilt. At this time, as long as the tilting directions of the two mounting side plates 7 are opposite, the tear test of the cardboard can be achieved in cooperation with the clamping plates 15 on both sides of the cardboard. If multi-layer testing or testing the rigidity of a carton is required, the multi-layer cardboard or carton can be placed directly between the fixed seat 1 and the sliding seat 2. Then, the sliding assembly is activated, causing the sliding seat 2 to move closer and closer to the fixed seat 1. Through the mutual clamping of the two sets of clamping components and the continuous increase of clamping force, the rigidity of the multi-layer cardboard or carton can be tested.
