Description

Technical Field

[0001] This invention relates to the technical field of rapid testing equipment for the compressive strength of cardboard boxes, specifically a rapid testing equipment for the compressive strength of cardboard boxes. Background Technology

[0002] In today's rapidly developing logistics and packaging industry, cardboard boxes are a common packaging material, and their compressive strength is a key indicator of whether they can effectively protect the contents from damage during transportation and storage.

[0003] However, traditional methods for testing the compressive strength of cartons have many problems that urgently need to be addressed. On the one hand, the operation process is cumbersome and complex. For example, the previous manual pressure testing method required precise positioning, installation, and pressure application for each carton. Each step had to strictly follow specific standards and specifications, and even slight errors could affect the accuracy of the test results. Moreover, during the testing process, various parameters needed to be constantly adjusted and recorded. The entire process not only required a high level of technical skill and experience from the operators but was also prone to errors due to human factors.

[0004] On the other hand, the testing cycle is relatively long, and the testing speed of traditional methods is difficult to keep up with the fast-paced rhythm of modern large-scale production lines. In some production scenarios, the compression strength test of a batch of cartons may take several hours or even longer to complete. This will undoubtedly slow down the entire production process, resulting in low production efficiency and an inability to provide timely data support for production decisions, thereby affecting product quality control and the timeliness of order delivery. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid testing device for the compressive strength of cardboard boxes, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a machine body, a support plate is provided at the bottom of the middle part of the machine body, a second hydraulic cylinder is provided at the bottom center of the support plate, a second telescopic rod is inserted into the end of the second hydraulic cylinder, the top of the second telescopic rod extends from the inside of the support plate, a lifting block is connected to the top of the second telescopic rod, a plurality of roller grooves are provided on the lifting block, rollers are held in the roller grooves, the two sides of the rollers are connected to the inner wall of the machine body, the top of the rollers extends from the roller grooves, and the top of the rollers is perpendicular to the surface of the conveyor belt.

[0007] Preferably, multiple sets of rollers are provided at both ends of the inner side of the machine body, and a conveyor belt is simultaneously fitted on the rollers on both sides. One end of the outermost roller at both ends of the machine body is inserted into the drive motors provided at both ends of the machine body. The drive motors can drive the rollers to rotate, so that the conveyor belt can be driven.

[0008] Preferably, a support frame is provided at the top of the middle part of the machine body, a first hydraulic cylinder is provided at the top center of the support frame, a first telescopic rod is inserted into the bottom of the first hydraulic cylinder, a pressure plate is connected to the bottom of the first telescopic rod, a pressure sensor is provided at the bottom center of the pressure plate, and the first hydraulic cylinder can drive the first telescopic rod to move the pressure plate to extend or retract.

[0009] Preferably, the center of the lifting block is parallel to the center of the first telescopic rod connected to the first telescopic rod. The lifting block has telescopic grooves at both ends, and springs are installed in the telescopic grooves. The bottom of the springs is connected to the bottom inner wall of the telescopic grooves, and the top of the springs is connected to an iron limiting plate. The springs can drive the iron limiting plate to extend and retract.

[0010] Preferably, the top two sides of the support plate are provided with support columns, which are perpendicular to the telescopic grooves opened at both ends of the lifting block. Multiple sets of through holes are opened at the bottom of the telescopic grooves. A strong magnet is connected to the top of the support column. When the lifting block is in the retracted state, the support column can drive the strong magnet to be inserted into the telescopic groove. The magnetic force of the strong magnet carries the tension of the spring.

[0011] Preferably, the lifting block has grooves on both sides of the top center, and a slider is held in the groove. The slider can slide in the groove. The top of the slider is connected to a baffle, and the two sides of the baffle extend to the top of the conveyor belts at both ends of the machine body.

[0012] Preferably, an adjusting bolt is connected to the middle of the rear end of the baffle. The adjusting bolt extends out of the outer side of the machine body from the extension slot opened in the middle of the support frame. An adjusting nut is sleeved on the outer side of the machine body. Tightening the adjusting nut can drive the baffle to move.

[0013] Preferably, sliding slots are provided on both sides of the middle part of the protrusion groove, and limit blocks are provided in the sliding slots. The adjusting bolt is simultaneously inserted into the sliding slot, and the sliding slot limits the adjusting bolt to prevent the adjusting bolt from being unable to move and fix the baffle.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention proposes a rapid testing device for the compressive strength of cartons. First, the device uses the extension slots on the outer side of the carton's width-adjusting bolts to drive the adjusting bolts to rotate. This causes two sets of adjusting bolts to retract and move the baffle. Simultaneously, the slider at the bottom of the baffle slides in the grooves on both sides of the top center of the lifting block to prevent the carton from shifting. Then, the cartons are placed one by one on the conveyor belt. Next, the drive motor is started, causing the roller shaft to rotate and the conveyor belt to begin transmission, conveying the cartons to the top of the lifting block in the middle of the machine. When the entire carton enters the top of the lifting block, the second hydraulic cylinder at the bottom of the support plate at the bottom of the middle of the machine starts to drive the second telescopic rod to extend and retract, causing the lifting block to rise. At this time, the rollers in the roller grooves on the lifting block retract into the grooves to prevent the roller grooves from rotating and causing the carton to fall from both ends of the lifting block. As the lifting block rises, the support plate at the top of the support columns at both ends of the lifting block... The magnet detaches from the bottom of the iron limiting plate, and the spring connected to the bottom of the iron limiting plate begins to release the iron limiting plate from the telescopic groove through tension. This causes the iron limiting plate to limit the two sides of the carton on the lifting block, preventing the carton from slipping. Then, the first hydraulic cylinder in the middle of the top of the support frame drives the first telescopic rod to press down the pressure plate, causing the pressure sensor at the bottom of the pressure plate to detect the pressure resistance of the carton. After the detection is completed, the second hydraulic cylinder drives the second telescopic rod to retract, resetting the lifting block. At this time, the strong magnet connected to the top of the support column extends into the telescopic groove through the through hole at the bottom of the telescopic groove. The telescopic groove begins to attract the bottom of the iron limiting plate through the strong magnet, attracting the iron limiting plate into the telescopic groove and releasing the limitation on both ends of the carton. At the same time, the top of the roller in the roller groove extends out from the top of the roller groove. Then, the conveyor belt drives another set of cartons to continue the transmission. The other set of cartons pushes the carton on the lifting block, replacing the carton being tested. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit 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.

[0024] Please see Figures 1 to 6 The present invention provides a technical solution: a machine body 1, a support plate 10 is provided at the bottom of the middle part of the machine body 1, a second hydraulic cylinder 11 is provided at the bottom middle of the support plate 10, a second telescopic rod 12 is inserted into the end of the second hydraulic cylinder 11, the top of the second telescopic rod 12 extends out from the inside of the support plate 10, the top of the second telescopic rod 12 is connected to a lifting block 13, a plurality of roller grooves 14 are provided on the lifting block 13, rollers 15 are held in the roller grooves 14, the two sides of the rollers 15 are connected to the inner wall of the machine body 1, the top of the rollers 15 extends out from the roller grooves 14, and the top of the rollers 15 is perpendicular to the surface of the conveyor belt 3; the rollers 15 in the roller grooves 14 provided on the lifting block 13 retract into the roller grooves 14 to prevent the roller grooves 14 from rotating and causing the cartons to fall from both ends of the lifting block 13;

[0025] Multiple sets of rollers 2 are arranged at both ends of the inner side of the machine body 1. Conveyor belts 3 are simultaneously mounted on the rollers 2 on both sides. One end of the outermost roller 2 at both ends of the machine body 1 is inserted into the drive motors 4 arranged at both ends of the machine body 1. The drive motors 4 can drive the rollers 2 to rotate, so that the conveyor belts 3 can be driven. A support frame 5 is arranged at the top of the middle of the machine body 1. A first hydraulic cylinder 6 is arranged at the top center of the support frame 5. A first telescopic rod 7 is inserted into the bottom of the first hydraulic cylinder 6. The bottom of the first telescopic rod 7 is connected to a pressure plate 8. A pressure sensor 9 is arranged at the bottom center of the pressure plate 8. The first hydraulic cylinder 6 can drive the first telescopic rod 7. The lifting block 13 is parallel to the center of the first telescopic rod 7, which is connected to the lifting block 13. The lifting block 13 has telescopic grooves 16 at both ends. Springs 17 are installed in the telescopic grooves 16. The bottom of the springs 17 is connected to the bottom inner wall of the telescopic grooves 16. The top of the springs 17 is connected to the iron limiting plate 18. The springs 17 can drive the iron limiting plate 18 to extend and retract. The springs 17 connected to the bottom of the iron limiting plate 18 start to push the iron limiting plate 18 out of the telescopic grooves 16 through tension, so that the iron limiting plate 18 limits the two sides of the carton on the lifting block 13 to prevent the carton from slipping.

[0026] Support columns 19 are provided on the top two sides of the support plate 10. The support columns 19 are perpendicular to the telescopic grooves 16 opened at both ends of the lifting block 13. Multiple sets of through holes are opened at the bottom of the telescopic grooves 16. A strong magnet 20 is connected to the top of the support column 19. When the lifting block 13 is in the retracted state, the support column 19 can drive the strong magnet 20 to be inserted into the telescopic groove 16. The magnetic force of the strong magnet 20 carries the tension of the spring 17. Slide grooves 21 are opened on both sides of the top of the middle part of the lifting block 13. A slider 22 is held in the slide groove 21. The slider 22 can slide in the slide groove 21. The top of the slider 22 is connected to the baffle 23. The sides of the baffle 23 extend to the top of the conveyor belts 3 at both ends of the machine body 1. The slider 22 at the bottom of the baffle 23 slides in the slide grooves 21 on both sides of the top of the lifting block 13 to prevent the carton from shifting.

[0027] An adjusting bolt 24 is connected to the middle of the rear end of the baffle 23. The adjusting bolt 24 extends out of the extension slot 25 opened in the middle of the support frame 5 and onto the outside of the machine body 1. An adjusting nut is fitted on the outside of the adjusting bolt 24 and the adjusting nut can drive the baffle 23 to move. Sliding slots 26 are opened on both sides of the middle of the extension slot 25. Limiting blocks 27 are set in the sliding slots 26. The adjusting bolt 24 is inserted into the sliding slots 26 at the same time. The sliding slots 26 limit the adjusting bolt 24 and prevent the adjusting bolt 24 from being unable to fix the movement of the baffle 23.

[0028] In actual use, first, adjust the outer extension slot 25 of the adjusting bolt 24 according to the width of the carton, drive the adjusting bolt 24 to rotate, so that the two sets of adjusting bolts 24 drive the baffle 23 to retract and move. At the same time, the slider 22 at the bottom of the baffle 23 slides in the sliding groove 21 on both sides of the top center of the lifting block 13 to prevent the carton from shifting. Then, place the carton one by one on the conveyor belt 3, and then start the drive motor 4 to drive the roller shaft 2 to rotate, so that the conveyor belt 3 starts to move, and conveys the carton to the lifting block 13 in the middle of the machine body 1. At the top, when the carton is fully inside the top of the lifting block 13, the second hydraulic cylinder 11 at the bottom of the support plate 10 located at the bottom of the middle part of the machine body 1 starts to drive the second telescopic rod 12 to extend and retract, causing the second telescopic rod 12 to lift the lifting block 13. At this time, the rollers 15 in the roller grooves 14 opened on the lifting block 13 retract into the roller grooves 14 to prevent the roller grooves 14 from rotating and causing the carton to fall from both ends of the lifting block 13. While the lifting block 13 is rising, the strong magnets 20 at the top of the support columns 19 located at both ends of the lifting block 13 on the support plate 10... The suction at the bottom of the iron limiting plate 18 is released, and the spring 17 connected to the bottom of the iron limiting plate 18 begins to eject the iron limiting plate 18 from the telescopic groove 16 through tension. This causes the iron limiting plate 18 to limit the two sides of the carton on the lifting block 13, preventing the carton from slipping. Then, the first hydraulic cylinder 6 at the top center of the support frame 5 starts to drive the first telescopic rod 7 to drive the pressure plate 8 down, causing the pressure sensor 9 at the bottom of the pressure plate 8 to detect the pressure resistance of the carton. After the detection is completed, the second hydraulic cylinder 11 drives the second telescopic rod 12 to retract, lifting the carton. When the lowering block 13 is reset, the strong magnet 20 connected to the top of the support column 19 extends into the telescopic groove 16 through the through hole at the bottom of the telescopic groove 16. The telescopic groove 16 begins to attract the bottom of the iron limiting plate 18 through the strong magnet, attracting the iron limiting plate 18 into the telescopic groove 16 and canceling the limiting of both ends of the carton. At the same time, the top of the roller 15 in the roller groove 14 extends out from the top of the roller groove 14. Then the conveyor belt 3 drives another set of cartons to continue to drive. The other set of cartons pushes the cartons on the lifting block 13 to replace the detection cartons.
