Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper box detection, and in particular to a wear-resistant corrugated paper box strength detection device. Background Art

[0002] Corrugated boxes are packaging containers made of corrugated cardboard, widely used in logistics, transportation, warehousing and other fields. Its structure is usually composed of face paper, core paper and lining paper. Its main features are lightness and strength. Generally, during the quality inspection during the production process, its wear resistance needs to be tested, because the box itself is prone to friction during transportation, so it needs to have a certain wear resistance.

[0003] A Chinese patent with authorization announcement number CN118310872B discloses a wear-resistant corrugated cardboard box strength testing machine, including a testing box, a testing base, a testing support plate, and a rotatable U-shaped frame. A driving assembly connected to the side U-shaped frame is fixed on the testing support plate; when the driving assembly drives the side U-shaped frame to rotate, the transmission assembly is also used to drive the testing box to rotate; the carton body is placed in the testing box, and this solution can realize the testing of the tumbling wear and compressive strength of the corrugated cardboard box.

[0004] The shortcomings of the above-mentioned prior art solutions are: although the above-mentioned solutions can simulate the tumbling of corrugated cardboard boxes and test their wear resistance, in actual situations, corrugated cardboard boxes filled with articles seldom tumble. The main reason may be the wear caused by the friction between the bottom of the box and the ground. Once the articles in the carton are too heavy, especially when loading, it is inconvenient for the porters to lift the carton, so the carton will slide along the ground or the floor of the carriage. In this process, the carton is subjected to the weight of the entire article, and the friction between the carton and the ground is large, which is prone to severe wear. Once the bottom is excessively worn, the articles will fall out. The above-mentioned solution is not convenient for wear testing the bottom of the carton filled with articles. Although the carton can be manually loaded with articles and then rubbed back and forth along the friction surface to check if the carton is damaged, the operation process is not convenient enough and the test effect is not good enough.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention uses a winch to lower the counterweight into the carton body to simulate the load, and the falling counterweight relies on the clutch transmission mechanism to realize the docking of the rotating end of the winch with the screw-type reciprocating drive mechanism. In this way, the winch does not need to be stopped and can continue to operate to provide power for the screw-type reciprocating drive mechanism. The screw sleeve in the screw-type reciprocating drive mechanism drives the sliding grinding plate to reciprocate along the reciprocating screw, thereby rubbing the bottom of the carton body after the load to perform a wear test.

[0021] 2. When the counterweight base plate of the counterweight part of the present invention descends to the inside of the carton body and stops, the counterweight frame at a certain distance from the counterweight base plate continues to descend, thereby linking the baffle plate through the extrusion action of the movable extrusion diagonal rod, thereby pushing the counterweight base plate to slide laterally. The counterweight base plate then drives the U-shaped slide in the clutch mechanism to slide laterally, thereby making the linkage wheel on the U-shaped slide contact with the driving wheel on the winch, so that the winch can drive the reciprocating screw to rotate through the driving wheel and the linkage wheel, and it is convenient to drive the sliding grinding plate to reciprocate, that is, the winch automatically completes the transmission docking with the reciprocating screw.

[0022] 3. The present invention can not only test the wear resistance of the carton body, but also seal or invert the carton body so that the bottom of the carton body faces upward, and then directly press the weight-adjusted counterweight down onto the carton body to test whether the carton body can bear the corresponding weight and complete the compressive strength test.

DETAILED DESCRIPTION

[0033] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] like Figure 1-Figure 8 As shown, a wear-resistant corrugated paper box strength testing equipment includes a testing platform 1, on which a sliding grinding plate 3 for rubbing the bottom of a paper box body 23 is slidably provided. When the paper box body 23 is fixed on the testing platform 1, the bottom of the paper box body 23 is rubbed by the sliding grinding plate 3 for a certain period of time, and then the damage of the bottom of the paper box body 23 is manually inspected and observed; here, a high-definition camera can be used to shoot the bottom of the paper box body 23, and the wear condition can be manually determined. The testing equipment also includes a lifting counterweight mechanism, a screw-type reciprocating drive mechanism and a clutch transmission mechanism. The lifting counterweight mechanism includes a counterweight and a winch. The winch is used to drive the counterweight to rise or fall. When the paper box body 23 is placed on the sliding grinding plate 3, the counterweight is lowered into the paper box body 23 by the winch, and the counterweight fixes and presses the paper box body 23 to simulate wear under load conditions;

[0035] The screw-type reciprocating drive mechanism drives the sliding grinding plate 3 to slide reciprocatingly relative to the detection platform 1 by rotating the screw, which is convenient for performing wear tests on the carton body 23 and detecting the wear resistance. The screw-type reciprocating drive mechanism cooperates with the rotating end of the winch through the clutch transmission mechanism. When the counterweight is in a raised state, the clutch transmission mechanism and the rotating end of the winch are in a separated state. When the counterweight descends to the bottom of the carton body 23, the clutch transmission mechanism and the rotating end of the winch are docked. In this way, after the counterweight presses the carton body 23 onto the sliding grinding plate 3, the winch rotates, and the screw-type reciprocating drive mechanism can be driven to operate through the clutch transmission mechanism, thereby driving the sliding grinding plate 3 to slide reciprocatingly, and performing a wear test on the bottom of the carton body 23.

[0036] In some specific embodiments, in combination Figures 2 to 6 As shown, the counterweight includes a counterweight base plate 14 and an auxiliary counterweight mechanism. A support plate 2 is fixedly connected to the top of the detection platform 1 through a bracket. The winch is installed on the support plate 2. The counterweight base plate 14 and the auxiliary counterweight mechanism are both arranged below the support plate 2, and a telescopic connecting rod 20 is arranged between the counterweight base plate 14 and the support plate 2. The telescopic connecting rod 20 relies on telescopic movement to facilitate the counterweight base plate 14 to move up and down smoothly; the auxiliary counterweight mechanism and the counterweight base plate 14 are both connected to the lifting end of the winch. The auxiliary counterweight mechanism facilitates the operator to increase or decrease the weight according to actual needs, that is, to adjust the weight.

[0037] Among them, Figure 6As shown, the auxiliary counterweight mechanism includes a counterweight frame 16 and a counterweight column 25. The counterweight frame 16 is connected to the lifting end of the winch. There are multiple groups of slots 24 distributed laterally and evenly on the counterweight frame 16. Each group of slots 24 includes two columnar slots. The slots 24 cooperate with the counterweight columns 25. When the counterweight needs to be increased or decreased, it can be achieved by adjusting the number of counterweight columns 25 placed, and the counterweight columns 25 are placed by relying on the slots 24.

[0038] In some specific embodiments, such as Figure 4 As shown, the clutch transmission mechanism includes a sliding mechanism and a transmission wheel mechanism. The sliding mechanism includes a U-shaped slide 12 and a connecting guide sleeve 13. The connecting guide sleeve 13 is fixedly arranged on one side of the support plate 2, and one end of the U-shaped slide 12 slides through the connecting guide sleeve 13. It should be noted that in order to prevent the U-shaped slide 12 from deflecting relative to the connecting guide sleeve 13, the corresponding end sections of the connecting guide sleeve 13 and the U-shaped slide 12 are both square sections. The transmission wheel mechanism is arranged at the other end of the U-shaped slide 12, and the transmission wheel mechanism is connected with the screw-type reciprocating drive mechanism. A linkage slide rod 15 is vertically fixedly connected to one side of the counterweight bottom plate 14. The linkage slide rod 15 vertically penetrates one end of the U-shaped slide 12, and the linkage slide rod 15 can slide longitudinally relative to the end of the U-shaped slide 12. When the counterweight is in the raised state, in order to prevent the support plate 2 from affecting the lifting of the linkage slide rod 15, a through hole is opened on the support plate 2, so that the linkage slide rod 15 can pass through the through hole when it is lifted together with the counterweight. A first connecting guide rail 21 is fixedly connected to the counterweight base plate 14, and the first connecting guide rail 21 is a T-shaped guide rail. The telescopic end of the telescopic connecting rod 20 is slidably connected to the first connecting guide rail 21 through a slider, and the telescopic end of the telescopic connecting rod 20 cannot be separated from the first connecting guide rail 21, and can only slide horizontally relative to each other. A limiting spring is also connected between the telescopic end of the telescopic connecting rod 20 and the first connecting guide rail 21; an extrusion mechanism for driving the counterweight base plate 14 to slide horizontally relative to the telescopic connecting rod 20 is provided between the auxiliary counterweight mechanism and the counterweight base plate 14.

[0039] Among them, Figure 3 As shown, the extrusion mechanism includes a movable extrusion oblique rod 22 and a linkage baffle 17. The movable extrusion oblique rod 22 is tiltably connected to the side of the auxiliary counterweight mechanism away from the U-shaped slide 12 through a rebound hinge. The linkage baffle 17 is fixedly connected to one side of the counterweight base plate 14, and the linkage baffle 17 is aligned and matched with the end of the movable extrusion oblique rod 22.

[0040] When the winch makes the counterweight base plate 14 and the auxiliary counterweight mechanism synchronously descend into the carton body 23, the linkage slide bar 15 on one side of the counterweight base plate 14 first slides longitudinally downward relative to the U-shaped slide 12. When the counterweight base plate 14 is pressed to the inside of the carton body 23 and cannot continue to descend, the auxiliary counterweight mechanism can continue to descend. At this time, the auxiliary counterweight mechanism will drive the movable extrusion inclined rod 22 to squeeze the linkage baffle 17. During the extrusion process, the movable extrusion inclined rod 22 deflects relative to the auxiliary counterweight mechanism, thereby pushing the linkage baffle 17, so that the linkage baffle 17 drives the counterweight base plate 14 to slide horizontally relative to the telescopic connecting rod 20 by relying on the first connecting guide rail 21. In this way, the counterweight base plate 14 pulls the U-shaped slide 12 to slide horizontally relative to the connecting guide sleeve 13 through the linkage slide bar 15, and the U-shaped slide 12 drives the transmission wheel mechanism to dock with the rotating end of the winch, thereby facilitating the operation of the screw-type reciprocating drive mechanism driven by the running winch.

[0041] It should be noted that in order to prevent the auxiliary counterweight mechanism from sliding left and right relative to the counterweight base plate 14 during the descent process, thereby affecting the extrusion action of the movable extrusion diagonal rod 22 to link the baffle plate 17, a limiting guide rod 18 is fixedly installed on the auxiliary counterweight mechanism. Specifically, the limiting guide rod 18 can be fixedly connected to the counterweight frame 16 of the auxiliary counterweight mechanism, the limiting guide rod 18 vertically penetrates the support plate 2, and the limiting guide rod 18 can slide longitudinally relative to the support plate 2.

[0042] It should also be noted that the end of the movable extrusion inclined rod 22 is a spherical end, which is convenient for deflection when the linkage baffle 17 is squeezed.

[0043] In some specific embodiments, the transmission wheel mechanism includes a linkage wheel 11, which is rotatably connected to the end of the U-shaped slide 12 away from the connecting guide sleeve 13 through a rotating shaft, and the linkage wheel 11 is coaxially connected to the screw-type reciprocating drive mechanism. The rotating end of the winch is coaxially connected to the driving wheel 10, and the driving wheel 10 cooperates with the linkage wheel 11, and anti-slip grooves are distributed on the wheel surfaces of both.

[0044] When the linkage wheel 11 contacts the driving wheel 10, the running winch will drive the linkage wheel 11 to rotate through the driving wheel 10, thereby realizing the rotation of the screw-type reciprocating drive mechanism.

[0045] In some specific embodiments, reference Figure 1 As shown, the screw-type reciprocating drive mechanism includes a reciprocating screw 6, a screw sleeve 7 and a linkage frame 5. The reciprocating screw 6 is coaxially connected to the linkage wheel 11, and the screw sleeve 7 is connected to the reciprocating screw 6. When the reciprocating screw 6 continues to rotate in one direction, the screw sleeve 7 moves back and forth laterally along the reciprocating screw 6. One end of the linkage frame 5 is fixedly connected to the screw sleeve 7, and a sliding connection mechanism is arranged between the other end and the sliding grinding plate 3.

[0046] Among them, the sliding connection mechanism includes a second connecting guide rail 4, which is fixedly connected to one side of the sliding grinding plate 3, and the second connecting guide rail 4 is perpendicular to the direction of the reciprocating screw 6, and the linkage frame 5 is slidingly connected to the second connecting guide rail 4 through a slider.

[0047] When the U-shaped slide 12 slides laterally and drives the linkage wheel 11 to contact the driving wheel 10, since the linkage frame 5 is slidably connected to the second connecting guide rail 4, the reciprocating screw 6, the screw sleeve 7 and the linkage frame 5 move laterally relative to the sliding grinding plate 3 with the U-shaped slide 12, and then the driving wheel 10 drives the linkage wheel 11 to rotate, and the linkage wheel 11 drives the reciprocating screw 6 to rotate, and the reciprocating screw 6 causes the screw sleeve 7 to slide reciprocatingly laterally. Since the reciprocating screw 6 is vertically distributed to the second connecting guide rail 4, the screw sleeve 7 can drive the sliding grinding plate 3 fixedly connected to the second connecting guide rail 4 to reciprocate laterally through the linkage frame 5. At this time, the carton body 23 has been pressed by the counterweight bottom plate 14, and the counterweight bottom plate 14 is connected to the support plate 2 by the telescopic connecting rod 20, the carton body 23 can be prevented from moving laterally with the sliding grinding plate 3, and the carton body 23 has a corresponding weight load, thereby facilitating the sliding grinding plate 3 to perform a wear test on the bottom of the carton body 23.

[0048] It should be noted that in order to facilitate the wear test of the carton body 23 by simulating different materials, the second connecting guide rail 4 has fixed connecting head mounting blocks at both ends, and the mounting blocks are fixedly connected to the sliding grinding plate 3 by bolts, which is convenient for disassembly and separation, and replacement of the sliding grinding plate 3 of different materials.

[0049] In some specific embodiments, the winch includes a winding column 8 and a lifting rope 9. The winding column 8 is rotatably arranged above the support plate 2, and an axis frame is fixedly connected to the support plate 2. The axis frames exist in pairs, and the winding column 8 is rotatably connected to the axis frame through a rotating shaft. The winding column 8 is driven to rotate by a servo motor. Two groups of lifting ropes 9 are arranged, and the winding is arranged at both ends of the winding column 8. A limited position perforation 19 is provided on the support plate 2. The end of the lifting rope 9 passes through the limited position perforation 19 and is connected to the telescopic end of the telescopic connecting rod 20. Specifically, the end of the lifting rope 9 and the telescopic connecting rod 20 can be connected together on a sliding block; the position of the lifting rope 9 near the end is connected to the auxiliary counterweight mechanism, that is, there is a section of lifting rope 9 between the auxiliary counterweight mechanism and the counterweight bottom plate 14, which is convenient for the counterweight bottom plate 14 to be lowered and pressed on the bottom of the carton body 23. Due to the certain softness of the lifting rope 9, the auxiliary counterweight mechanism can also be lowered relative to the counterweight bottom plate 14.

[0050] And when the sliding grinding plate 3 is tested by reciprocating friction against the pressed carton body 23, the winding column 8 continuously lifts the lifting rope 9 until the lifting rope 9 is completely released. Then, the winding column 8 continues to be reeled in, and the lifting rope 9 will be rolled up in the opposite direction. In this way, the counterweight base plate 14 will be finally pulled up again by the lifting rope 9, thus completing the wear test without manual control of stopping the machine or reversing the winding column 8.

[0051] In addition, the present invention can also perform a compressive strength test on the carton body 23. When performing the wear resistance strength test, the carton body 23 can be in an open state. When performing the compressive strength test, the opening of the carton body 23 is sealed or inverted, and then the counterweight bottom plate 14 is directly pressed from the bottom to the top of the carton body 23, and the counterweight is adjusted through the auxiliary counterweight mechanism to test how much weight the carton body 23 can withstand, thereby facilitating the judgment of whether the overall compressive strength of the carton body 23 meets the standard.

[0052] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0053] First, place the open carton body 23 on the sliding grinding plate 3, and then start the servo motor connected to the winding column 8, so that the servo motor drives the winding column 8 to release the lifting rope 9, and the lifting rope 9 lowers the counterweight base plate 14. When the counterweight base plate 14 is pressed to the inside of the carton body 23 and cannot continue to descend, the counterweight frame 16 of the auxiliary counterweight mechanism can continue to descend. At this time, the counterweight frame 16 will drive the active extrusion inclined rod 22 to squeeze the linkage baffle 17. During the extrusion process, the active extrusion inclined rod 22 deflects relative to the counterweight frame 16, thereby Push the linkage baffle 17, so that the linkage baffle 17 drives the counterweight base plate 14 to slide horizontally relative to the telescopic end of the telescopic connecting rod 20 by relying on the first connecting guide rail 21, and the set limit spring is compressed to generate a rebound force, so that the counterweight base plate 14 pulls the U-shaped slide 12 to slide horizontally relative to the connecting guide sleeve 13 through the linkage slide rod 15; it should be noted that when the counterweight base plate 14 descends to the bottom of the carton body 23 and stops, the top of the linkage slide rod 15 is already lower than the height position of the support plate 2, so there will be no movement hindrance.

[0054] When the U-shaped slide 12 slides horizontally, the linkage wheel 11 is driven to contact the driving wheel 10. Since the linkage frame 5 is slidably connected with the second connecting guide rail 4, the reciprocating screw 6, the screw sleeve 7 and the linkage frame 5 move horizontally relative to the sliding grinding plate 3 along with the U-shaped slide 12. Then the driving wheel 10 drives the linkage wheel 11 to rotate, and the linkage wheel 11 drives the reciprocating screw 6 to rotate. The reciprocating screw 6 makes the screw sleeve 7 slide back and forth horizontally. Since the reciprocating screw 6 is vertically distributed with the second connecting guide rail 4, the screw sleeve 7 can pass through the linkage frame 5 drives the sliding grinding plate 3 fixedly connected to the second connecting guide rail 4 to move horizontally back and forth. Since the carton body 23 is pressed by the counterweight bottom plate 14 at this time, and the counterweight bottom plate 14 is connected to the support plate 2 by means of the telescopic connecting rod 20 and extends into the interior of the carton body 23, it can prevent the carton body 23 from moving horizontally with the sliding grinding plate 3, and the carton body 23 has a corresponding weight load, so that the sliding grinding plate 3 can be used to perform a wear test on the bottom of the carton body 23 to simulate whether the friction between the bottom of the carton body 23 and the ground occurs when the carton body 23 is under load.

[0055] During the reciprocating friction test of the sliding wear plate 3 relative to the pressed carton body 23, the winding column 8 continuously lifts the lifting rope 9 until the lifting rope 9 is completely released. Then, the winding column 8 continues to be reeled in, and the lifting rope 9 will be rolled up in the opposite direction. In this way, the counterweight base plate 14 will be pulled up again by the lifting rope 9 eventually, and the wear test is completed without manual control to stop the machine or control the reversal of the winding column 8. That is, after a certain period of time, the counterweight base plate 14 automatically rises, and then the tester removes the carton body 23 and observes the wear condition of the bottom of the carton body 23 through relevant auxiliary equipment, so as to judge the wear resistance of the carton body 23.

[0056] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
