DETAILED DESCRIPTION

[0021] 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.

[0022] Example 1, Reference Figures 1 to 16 The impact resistance testing device for carton production shown in the figure comprises a baffle 2, four support frames 4 and a slide bar 10 are arranged at the upper end of each baffle 2, a top cover is arranged at the upper end of each of the four support frames 4, a transmission chain 3 is arranged between the top cover and the baffle 2, a carton 7 is arranged at the middle of the upper end of the baffle 2, a pressure mechanism 8 for performing an impact test on the carton 7 is arranged between the four transmission chains 3, and a collision mechanism 9 for changing the impact area to perform an impact resistance test on the carton 7 is arranged inside the pressure mechanism 8; A deformation detection mechanism 5 is provided in the middle of the outer surface of the carton 7 for detecting the degree of wrinkles on the surface of the carton after an impact test, and a binding force bearing mechanism 6 is provided on the outer surface of the carton 7 for detecting the influence of the binding strap on the bearing capacity of the carton 7; The upper end of the baffle plate 2 is provided with a transparent shell 1 to prevent the water mist sprayed from the vent plate tube 811 from escaping, and the baffle plate 2 is rotatably mounted on one side of the transparent shell 1; It is worth noting that the carton 7 is placed on the upper end of the baffle 2, and then the pressure mechanism 8 is driven by the transmission chain 3 to move downward to squeeze the carton 7 through the collision mechanism 9 to test the carrying capacity of the carton 7, and the pressure mechanism 8 is moved to the highest point through the transmission chain 3, and then the mechanical connection between the driving mechanism inside the baffle 2 and the transmission chain 3 is disconnected, so that the pressure mechanism 8 is free to fall and hit the carton 7 through the collision mechanism 9 to perform an impact test on the carton 7; A variety of impact test methods are provided by cooperating between the pressure-applying mechanism 8 and the impact mechanism 9 to simulate various pressures and impacts that the carton 7 may encounter during actual transportation and storage, such as stacking, handling, and falling, so as to more accurately evaluate the pressure resistance and impact resistance of the carton 7; In addition, the transmission chain 3 controls the downward pressure of the pressure-applying mechanism 8, so as to quantify the load-bearing capacity of the carton 7 and determine its deformation degree and limit value under different pressures.

[0023] The deformation detection mechanism 5 and the binding force bearing mechanism 6 are arranged on the surface of the carton 7, and the binding force bearing mechanism 6 can be arranged according to the force borne by the binding belt of the carton 7 in the binding state and the load of the carton 7 in the binding state, and the deformation detection mechanism 5 can be arranged according to the deformation degree of the surface of the carton 7 when the carton 7 is impacted by the pressure applying mechanism 8; Among them, the deformation detection mechanism 5 can monitor in real time the deformation degree of the surface of the carton 7 when it is impacted, and the binding force mechanism 6 can measure the force borne by the binding straps of the carton 7 in the bound state, as well as the load-bearing capacity of the carton 7 in the bound state.

[0024] By testing the deformation detection mechanism 5 and the binding force mechanism 6, the weak links in the design of the carton 7 can be discovered, so that targeted improvements can be made. For example, if the deformation of a certain area of ​​the carton 7 is particularly large, you can consider increasing the structural strength of the area or changing the material. For the force condition of the straps, you can optimize the position and number of the straps to improve the overall stability and safety of the carton 7.

[0025] Embodiment 2: Based on the pressure-applying mechanism 8 proposed in Embodiment 1, this embodiment provides a further technical solution of the pressure-applying mechanism 8.

[0026] Slide blocks 86 slidably mounted on the outer surface of the slide rod 10 are provided on both sides of the pressure plate 89, auxiliary wheels 81 are provided at the four corners of the upper end of the pressure plate 89 for contacting the surface of the support frame 4 to assist the pressure plate 89 to move up and down, a chain clamp 87 fixed to the transmission chain 3 is provided at the upper end of the pressure plate 89, and the upper ends of the two atomizers 82 are commonly connected to a water pipe 83.

[0027] A stop column 84 is provided at the middle of the upper end of the pressure plate 89 , and a counterweight block 85 is provided at the upper end of the pressure plate 89 to increase the weight of the pressure plate 89 during the impact test. A mounting groove 88 is provided at the lower end of the pressure plate 89 .

[0028] It is worth noting that when the carton 7 is subjected to impact testing, the driving mechanism inside the baffle 2 drives the transmission chain 3 to drive, and the transmission chain 3 drives the pressure plate 89 to move downward through the chain clamp 87, and the collision mechanism 9 inside the mounting groove 88 also moves downward to squeeze the carton 7, and the pressure plate 89 is continuously driven by the transmission chain 3 to move downward to squeeze the carton 7, and the carton 7 is slowly pressed to test the carrying capacity of the carton 7; When in use, the pressure plate 89 can be moved to the top through the transmission chain 3, and a counterweight block 85 can be added to the surface of the baffle column 84 to increase the weight of the pressure plate 89. When the carton 7 is subjected to an impact test, the transmission connection between the internal driving mechanism of the baffle 2 and the transmission chain 3 is cut off to allow the pressure plate 89 to fall freely. The pressure plate 89 then pushes the collision mechanism 9 to impact the carton 7, thereby testing the impact resistance of the carton 7.

[0029] The transmission connection between the internal drive mechanism of the cutting baffle 2 and the transmission chain 3 belongs to the existing technical means and will not be described here in detail. The auxiliary wheel 81 and the slider 86 are provided to help the pressure plate 89 not to shift when sliding.

[0030] Among them, by continuously driving the pressure plate 89 to move downward through the transmission chain 3, the carton 7 is slowly pressed, so as to test the load-bearing capacity of the carton and evaluate its performance under long-term pressure; By cutting off the transmission connection between the internal driving mechanism of the baffle 2 and the transmission chain 3, the pressure plate 89 is allowed to fall freely, and the collision mechanism 9 is pushed to impact the carton 7, so that the impact resistance of the carton can be tested and its performance under sudden impact can be evaluated.

[0031] The pressure mechanism 8 includes a pressure plate 89, and two atomizers 82 are symmetrically arranged inside the pressure plate 89, and the lower ends of the two atomizers 82 are provided with ventilation plate tubes 811 for moisture-proof detection of the carton 7, and the lower ends of the two ventilation plate tubes 811 are provided with nozzles 812 for increasing the water mist spraying effect of the ventilation plate tubes 811, and the opposite surfaces of the two ventilation plate tubes 811 are provided with a plurality of through holes 813 distributed in a rectangular array.

[0032] Among them, when the carton 7 is subjected to continuous pressure from the collision mechanism 9 or when the pressure plate 89 drives the collision mechanism 9 to collide or press on its surface, the atomizer 82 can be opened to generate water mist which is sprayed out through the through hole 813 of the ventilation plate tube 811 and the nozzle 812. The sprayed water mist can be directly adsorbed on the surface of the carton 7, so that the moisture condition of the carton 7 can be detected through long-term water mist erosion, and the carrying capacity of the carton 7 can be detected according to the moisture condition of the carton 7.

[0033] Among them, carton 7 is subjected to dual tests of compression resistance and moisture resistance. By conducting compression resistance and moisture resistance tests at the same time, the various challenges that carton 7 may encounter in the actual use environment, such as humidity changes, rain soaking, etc., can be fully evaluated to ensure the performance of carton 7 under various conditions.

[0034] The atomizer 82 can simulate hot and humid environments, such as transportation on rainy days and humid warehouses, and more realistically reflect the performance of the carton 7 in these environments. Through long-term water mist erosion, the durability and stability of the carton 7 under continuous humid conditions can be tested. Through testing, the weak links of the carton 7 under humid conditions can be discovered, such as high water absorption and decreased strength, providing a basis for improving the design.

[0035] Embodiment 3: Based on the binding force-bearing mechanism 6 and the deformation detection mechanism 5 proposed in Embodiment 1, this embodiment provides a further technical solution for the binding force-bearing mechanism 6 and the deformation detection mechanism 5.

[0036] The binding force mechanism 6 includes a mounting frame 64 and a second strap 61 tied to the outer surface of the carton 7. Two rollers 65 are rotatably installed inside the mounting frame 64, and rectangular grooves 66 are provided on both sides of the mounting frame 64. A clamping frame 63 is provided on one side of the mounting frame 64. Rectangular grooves 66 are provided on both sides of the mounting frame 64. One end of the clamping frame 63 is connected to a tension sensor 62, and both ends of the second strap 61 pass through the rectangular groove 66 and are connected to one end of the tension sensor 62.

[0037] It is worth mentioning that when in use, the second strap 61 is tied to the upper and lower sides of the outer surface of the carton 7. When the carton 7 is subjected to impact force, the shape of the carton 7 is deformed, and the deformation of the carton 7 causes the second strap 61 to be subjected to a pulling force. The tension sensor 62 tied to one end of the second strap 61 can detect the force generated by the deformation of the carton 7. The roller 65 can assist the second strap 61 to enter the interior of the card frame 63 and be fixed together with one end of the tension sensor 62. The tension sensor 62 is a tension sensor in the prior art. The tension sensor 62 is a mature technology that can provide reliable force value data and can detect the force applied to the second strap 61 after the carton 7 is impacted.

[0038] Among them, the tension sensor 62 can detect in real time the deformation of the carton 7 when it is subjected to impact force. Through the change of the pulling force of the second strap 61, the deformation degree of the carton 7 under different impact conditions can be monitored to evaluate its structural strength and stability.

[0039] Furthermore, by monitoring the pulling force of the second binding strap 61, the deformation of the carton 7 at a specific position can be discovered, and the weak links in the carton design can be identified, providing a basis for improving the design.

[0040] The deformation detection mechanism 5 includes four bottom shells 55 and corner blocks 52 stuck at the corners of the carton 7. Twisted rope rods 511 are rotatably installed on both sides of the inside of the four bottom shells 55. The outsides of the two twisted rope rods 511 are wrapped with first straps 54, and the outer surfaces of the two twisted rope rods 511 are provided with second torque springs 512. Two partitions 58 are symmetrically arranged on the inner wall of the bottom shell 55. A center rod 57 is arranged in the middle of the inner wall of the bottom shell 55, and a dial 56 is rotatably installed on the outer surface of the center rod 57. The outer surface of the center rod 57 is sleeved with a first torque spring 59; It is worth mentioning that when in use, the four corner blocks 52 and the bottom shell 55 are all fitted and fixed in the middle of the outer surface of the carton 7, and the length of the first strap 54 is adjusted by the clamping block 53. When the carton 7 is subjected to impact detection, the surface of the carton 7 will be deformed due to the impact force. When the carton 7 collapses completely, the deformation detection mechanism 5 set will not be able to detect the deformation degree of the carton 7. When the surface of the carton 7 is deformed, the deformed surface of the carton 7 will contact the bottom shell 55, and the bottom shell 55 is pushed to pull the first strap 54 to drive the twisting rope rod 511 to rotate, and the twisting rope rod 511 will drive the second torque spring 512 to twist.

[0041] Two mounting posts 513 are symmetrically arranged on one side of the scale plate 56 . A connecting rope 514 is connected between the two mounting posts 513 and the rope-twisting rod 511 . A pointer cover 51 is arranged on the outer surface of the scale plate 56 .

[0042] A clamping block 53 is disposed on both sides of the four corner blocks 52 , and one end of the first binding belt 54 is fixed inside the clamping block 53 .

[0043] Among them, when the rope rod 511 rotates, the connecting rope 514 will also be wrapped around the surface of the rope rod 511. When the connecting rope 514 is wrapped around the surface of the rope rod 511, it will also pull the mounting column 513 to move. The mounting column 513 drives the dial 56 to rotate on the outer surface of the center rod 57. Through the rotation of the dial 56, the scale on the surface of the dial 56 and the pointer on the surface of the pointer cover 51 are offset, so as to detect the degree of deformation of the surface of the carton 7 after the carton 7 is impacted.

[0044] Among them, through the stretching of the first binding strap 54 and the rotation of the rope rod 511, the deformation of the surface of the carton 7 can be accurately detected, and the deformation detection mechanism 5 can monitor the deformation of the carton 7 when it is subjected to impact force in real time.

[0045] Embodiment 4: The collision mechanism 9 includes a flat plate 111 , and the bottom of the flat plate 111 is smooth and slidably mounted inside the mounting groove 88 .

[0046] It is worth noting that the bottom of the flat plate 111 is in a flat state, and the pressure plate 89 can be driven by the transmission chain 3 to slowly apply pressure to the carton 7, and the load-bearing capacity of the carton 7 can be detected by the flat plate 111.

[0047] Embodiment 5: The collision mechanism 9 includes an arc block 121 . The cross section of the arc block 121 is in a semi-cylindrical shape, and the arc block 121 is slidably installed inside the installation groove 88 .

[0048] It is worth noting that the arc block 121 is in the shape of a semi-cylinder, and the arc block 121 can hit the surface of the carton 7 to simulate the deformation degree of the carton 7 after the carton 7 is subjected to the impact force when being transported.

[0049] Embodiment 6: The impact mechanism 9 includes an impact block 131 . The cross section of the impact block 131 is triangular in shape, and the impact block 131 is slidably installed inside the installation groove 88 .

[0050] It is worth noting that the impact block 131 is in the shape of a triangular prism, and the impact block 131 can hit the surface of the carton 7 to simulate the degree of deformation of the carton 7 after the carton 7 is subjected to impact force when being transported.

[0051] The present invention also provides a method for using an impact resistance testing device for carton production, and the specific method of use is as follows: S1. Place the carton 7 on the upper end of the baffle 2, and then drive the pressure mechanism 8 to move downward through the transmission chain 3 to squeeze the carton 7 through the collision mechanism 9 to test the carrying capacity of the carton 7. Move the pressure mechanism 8 to the highest point through the transmission chain 3, and then disconnect the mechanical connection between the driving mechanism inside the baffle 2 and the transmission chain 3, so that the pressure mechanism 8 falls freely and hits the carton 7 through the collision mechanism 9 to perform an impact test on the carton 7; A variety of impact test methods are provided by cooperating between the pressure-applying mechanism 8 and the impact mechanism 9 to simulate various pressures and impacts that the carton 7 may encounter during actual transportation and storage, such as stacking, handling, and falling, so as to more accurately evaluate the pressure resistance and impact resistance of the carton 7; In addition, the transmission chain 3 controls the downward pressure of the pressure-applying mechanism 8, so as to quantify the load-bearing capacity of the carton 7 and determine its deformation degree and limit value under different pressures.

[0052] S2, a deformation detection mechanism 5 and a binding force mechanism 6 are arranged on the surface of the carton 7, and the binding force mechanism 6 can be arranged according to the force borne by the binding belt of the carton 7 in the binding state, and the load of the carton 7 in the binding state, and the deformation detection mechanism 5 can be arranged according to the deformation degree of the surface of the carton 7 when the carton 7 is impacted by the pressure mechanism 8; Among them, the deformation detection mechanism 5 can monitor in real time the deformation degree of the surface of the carton 7 when it is impacted, and the binding force mechanism 6 can measure the force borne by the binding straps of the carton 7 in the bound state, as well as the load-bearing capacity of the carton 7 in the bound state.

[0053] By testing the deformation detection mechanism 5 and the binding force mechanism 6, the weak links in the design of the carton 7 can be discovered, so that targeted improvements can be made.
