Description

Technical Field

[0001] The present application relates to the technical field of packaging box waterproof detection, and in particular to a gift packaging box waterproof performance detection device and detection method. Background Art

[0002] The wine and beverage packaging boxes commonly sold on the market are injection molded packaging boxes, which use paper substrates as the base material. The outer surface of the paper substrate is coated with waterproof material and covered with various anti-counterfeiting films and plastic films to ensure the beauty and strength of the packaging box.

[0003] Since wine and beverages may be damaged during transportation, resulting in wine leakage, and the quality of the product in the packaging box may be affected by moisture due to rainy weather or humid environment during transportation, it is often necessary to conduct a waterproof test on the packaging box before packaging the product.

[0004] There are three common methods for testing the waterproofness of packaging boxes: visual method, weight method and water pressure method.

[0005] The visual method is to apply water to the outer surface of the package box to be tested, and observe whether there are water droplets floating on the surface of the package and whether the water droplets are absorbed. If the water droplets float and are not absorbed, it means that the waterproof performance is good, otherwise the waterproof performance is poor.

[0006] The weight method is to put the packaging box to be tested under load, then apply water on the surface of the packaging box, and weigh it again after the surface water has fully penetrated. The difference between the two weighings is compared to determine the waterproof performance of the packaging box.

[0007] The water pressure method compresses the packaging box to be tested and immerses it in water, gradually increasing the water pressure to observe whether the packaging box is leaking, thereby judging and evaluating the waterproof performance of the packaging box.

[0008] Regarding the above-mentioned related technologies, the transportation loss and product loss customized during the production and transportation process are different depending on the products in the packaging box and the transportation environment. At the same time, the internal and external waterproof requirements of the packaging box are inconsistent depending on the products. For example, for fragile wine and beverages, it is necessary to reduce the impact of the wine and beverage breakage and spillage on other surrounding packaging boxes. The waterproof performance during transportation is mainly determined by the waterproof performance of the outside of the packaging box. When performing waterproof testing using the above method, it is not easy to directly judge the quality of the internal and external waterproof performance of the packaging box, so it needs to be improved. Summary of the invention

[0009] In order to facilitate the detection of the waterproof performance of the inside and outside of the packaging box, the present application provides a gift packaging box waterproof performance detection device and detection method.

[0010] The present application provides a gift box waterproof performance testing device and testing method using the following technical solutions: A gift box waterproof performance testing device and testing method, comprising a frame, a workbench arranged on the frame, and a positioning block arranged on the frame, wherein the workbench is provided with a limiting structure for limiting the position of the box, the positioning block is movably inserted into the box, the positioning block is in contact with two opposite inner side walls of the box that do not need to be tested, and the positioning block is also provided with an internal testing component for performing an internal waterproof test on the box and an external testing component for performing an external waterproof test on the outer wall of the box; The inner detection assembly comprises a first detection block and a first abutting block slidably arranged on the positioning block, the first detection block and the first abutting block are arranged opposite to each other, and a clamping cavity for clamping the side wall of the packaging box is reserved between the first detection block and the first abutting block, a first detection hole is opened on the first detection block, a liquid storage tank connected to the first detection block is provided on the frame, a power piece is provided in the liquid storage tank, and the liquid in the liquid storage tank of the power piece is squeezed out from the first detection hole, and the first detection block is in contact with the inner wall of the packaging box; The external detection assembly includes a second detection block and a second abutting block slidably disposed on the positioning block, a clamping cavity for clamping the side wall of the packaging box is reserved between the second detection block and the second abutting block, a second detection hole is opened on the second detection block, the second detection block is also connected to the liquid storage tank, the second detection block is in contact with the outer side wall of the packaging box, and the first detection block is connected to the second detection block; The first pressing block and the second pressing block are both provided with a marking box, in which fluorescent powder is stored, and the first pressing block and the second pressing block are provided with a coating member for coating the side wall of the packaging box with fluorescent powder, and the first pressing block and the second pressing block are also provided with a camera member for taking an image of the side wall of the packaging box.

[0011] By adopting the above technical solution, since the internal and external waterproof performances of the packaging box directly affect the transportation loss during product transportation and the packaging loss during product packaging, it is also convenient to improve the material, process, etc. of the packaging box according to the transportation loss and packaging loss, thereby improving the product quality of the packaging box.

[0012] When testing the waterproof performance of a packaging box, first place the packaging box on a workbench, then insert the provided positioning block into the packaging box to fit tightly against the inner bottom wall of the packaging box, so that the packaging box is not easily deviated or shaken during subsequent waterproof testing.

[0013] It should be noted at this point that, when conventionally testing the waterproof performance of a packaging box, the packaging box is usually unfolded and then the flat packaging cardboard is tested for permeability. However, the use of the packaging box, especially folding, will affect the permeability and waterproof performance of the packaging box. Therefore, the present application performs a waterproof performance test on the packaging box after it is folded, that is, to simulate the state of the packaging box during use, so as to obtain a more accurate result of the waterproof performance of the packaging box.

[0014] When performing waterproof detection, the first detection block is fitted with the inner wall of the packaging box, and the first pressing block is fitted with the outer wall of the packaging box. The first detection block and the first pressing block form a space to enclose the side wall of the packaging box. At this time, the power component sprays the liquid in the liquid storage tank to the inner wall of the packaging box through the first detection hole, and sprays fluorescent powder on the inner wall of the packaging box through the first pressing block, and takes an image of the inner wall of the packaging box through the camera component. Since the wetness of the inner wall of the packaging box directly affects the adhesion performance of the packaging box, it is convenient to judge the waterproof performance of the outer wall of the packaging box according to the degree and amount of fluorescent powder adhered to the inner wall of the packaging box.

[0015] At the same time, a second detection block is arranged to fit with the outer wall of the packaging box, and a second pressing block is arranged to fit with the inner wall of the packaging box. The second detection block sprays water toward the outer wall of the packaging box, and at the same time, the second pressing block sprays fluorescent powder toward the inner wall of the packaging box, so as to judge the waterproof performance of the inner wall of the packaging box according to the degree and quantity of fluorescent powder adhered to the outer wall of the packaging box.

[0016] After obtaining the different waterproof properties of the inner wall and the outer wall of the packaging box through the above scheme, the difference in waterproof properties between the inner wall and the outer wall of the packaging box is obtained, and then the transportation loss and packaging loss data of the packaging box are obtained based on this difference.

[0017] Optionally, the liquid storage tank is provided with a connecting tube connected to the first detection block and the second detection block, an adjusting plate is rotatably connected in the connecting tube, the adjusting plate is movably fitted with the inner wall of the connecting tube, the adjusting plate movably blocks the connecting tube, and the first clamping block and the second clamping block are also provided with marking parts for marking the side walls of the packaging box according to the impact force of the water flow at the first detection hole and the second detection hole.

[0018] By adopting the above technical solution, the area through which the water flows in the connecting pipe is adjusted by the setting of the adjustment plate. Since the power component is a water pump, the amount of water entering the connecting pipe is fixed. When the water in the connecting pipe passes through the connecting pipe, the water flow velocity will also change, thereby changing the water flow impact force at the first detection hole and the second detection hole, thereby facilitating the subsequent judgment of the waterproof performance of the packaging box under different impact forces according to the change in the water flow velocity.

[0019] At the same time, by setting a marking part, the packaging box is marked when the water flow impact force changes, so that it can be used as a base point for the change of water flow speed in subsequent photography to judge the change of water flow speed and thus judge the change of water flow impact force.

[0020] Optionally, a first adjusting gear is provided at the rotating shaft of the adjusting plate, a first adjusting rack is provided on the positioning block, and the first adjusting gear is meshed with the first adjusting rack.

[0021] By adopting the above technical solution, when the first detection block and the second detection block are driven to slide and the waterproof performance of the side wall of the packaging box is tested, the first adjustment rack does not slide, and the first adjustment gear is driven to rotate by the first adjustment rack, thereby realizing the rotation drive of the adjustment plate, and realizing the adjustment of the area through which the water flows in the connecting pipe, thereby realizing the adjustment of the water flow impact at the first detection hole and the second detection hole.

[0022] Optionally, the marking member includes a marking block slidably arranged on the first clamping block / the second clamping block, the marking block movably protruding from the first clamping block / the second clamping block, the first clamping block and the second clamping block are both provided with a receiving groove, the marking block is elastically slidably arranged in the receiving groove, the first clamping block and the second clamping block are both rotatably connected to a second adjusting rod, the second adjusting rod is provided with a plurality of limit blocks, the marking block is provided with an abutment block, the limit block is movably fitted with the abutment block, and the end side of the limit block and the abutment block that are movably fitted is inclined, the second adjusting rod is provided with a second adjusting gear, the first detection block and the second detection block are both rotatably provided with flow equalizing blades, and the flow equalizing blades rotate synchronously with the second adjusting gear.

[0023] By adopting the above technical scheme, when the adjusting plate rotates to adjust the area through which the water flows in the connecting pipe, the water flow speed in the first detection block and the second detection block changes, thereby changing the water flow speed that impacts the flow balancing blade. When the flow balancing blade rotates, it drives the second adjusting gear to rotate synchronously. Every time the adjusting gear rotates through a cycle, the second adjusting rod also rotates through a cycle, that is, multiple limit blocks are sequentially fitted with the abutment blocks, and the abutment blocks protrude under the action of the limit blocks and the elastic restoring force, thereby driving the marking block to protrude from the first abutment block / second abutment block arrangement. At the same time, the marking block marks the inner wall or outer wall of the packaging box, so that it is convenient to judge the rotation speed of the flow balancing blade according to the change in the distance between two adjacent marking points by the camera in the subsequent time, thereby realizing the judgment of the waterproof performance of the packaging box under different subsequent water flow speeds.

[0024] Optionally, a coating hole is provided on one side of the first clamping block close to the outer wall of the packaging box and a coating hole is provided on one side of the second clamping block close to the inner wall of the packaging box, and the coating hole is communicated with the marking box. A negative pressure hole is provided on the first clamping block and the second clamping block, and a negative pressure blade is rotatably arranged in the negative pressure hole. A coating blade is rotatably arranged in the coating hole, and the negative pressure blade and the coating blade rotate synchronously with the adjusting rod.

[0025] By adopting the above technical scheme, when the water flow impacts the flow-equalizing blade to rotate, driving the second adjusting gear and the adjusting rod to rotate, the adjusting rod rotates to drive the negative pressure blade and the butcher blade to rotate, thereby squeezing the fluorescent powder in the marking box through the coating hole, and coating the outer wall and the inner wall of the packaging box with the fluorescent powder. The rotation of the negative pressure blade causes negative pressure to be generated in the negative pressure hole, thereby absorbing the excess fluorescent powder on the outer wall and the inner wall of the packaging box, and the fluorescent powder that is not absorbed can more easily and accurately reflect the waterproof performance of the packaging box, thereby facilitating relevant personnel to accurately judge the waterproof performance of the packaging box under different water flows and water pressures.

[0026] Optionally, a first bevel gear is provided on the adjusting rod, and second bevel gears are provided on the rotating shafts of the coating blade and the negative pressure blade, and the first bevel gear is meshed with the two second bevel gears.

[0027] By adopting the above technical solution, when the water flow impacts the flow-equalizing blade to rotate, the flow-equalizing blade drives the adjusting rod to rotate, and the first bevel gear on the adjusting rod drives the coating blade and the second bevel gear on the negative pressure blade shaft to rotate, thereby realizing the rotation drive of the coating blade and the flow-equalizing blade, so as to continuously coat and absorb the fluorescent powder on the outer circumferential wall and the inner circumferential wall of the packaging box, reduce the input of external power source, and thus reduce the operating steps of relevant technical personnel when conducting waterproof performance testing.

[0028] Optionally, a bracket is connected between the first detection block and the second detection block, the first detection block and the second detection block are both slidably set on the bracket, the first clamping block and the second clamping block are both fixed on the bracket, and the bracket is also provided with a driving member for synchronously slidingly adjusting the first detection block and the second detection block.

[0029] By adopting the above technical solution, when the waterproof performance of the packaging box needs to be tested, it is only necessary to slide the bracket through the driving member to achieve synchronous sliding of the first detection block and the second detection block, thereby achieving driving in the width direction of the packaging box.

[0030] Optionally, the driving member includes a driving screw rotatably set on the bracket, the driving screw is provided with an external thread with the same pitch, and the first detection block and the second detection block are both threadedly set on the driving screw, and the first clamping block and the second clamping block are also provided with sealing members for movably sealing the coating hole and the negative pressure hole.

[0031] By adopting the above technical solution, the external power source drives the screw to rotate, thereby driving the first detection block and the second detection block to slide along the length direction of the driving screw, thereby realizing waterproof performance testing of packaging boxes of different widths and sizes.

[0032] At the same time, in the process of testing the waterproof performance of the first test block and the second test block, when the test is completed, the coating holes and the negative pressure holes need to be sealed to reduce the waste of fluorescent powder. Therefore, the coating holes and the negative pressure holes are sealed through the provided sealing parts, thereby saving fluorescent powder and reducing the waste of resources.

[0033] Optionally, the sealing member includes a sealing plate slidably arranged on the first clamping block / the second clamping block, the sealing plate is liftably arranged on the first clamping block / the second clamping block, and a movable block is slidably arranged on the first clamping block / the second clamping block, the movable block movably protrudes from the first clamping block / the second clamping block, one end of the movable block protruding from the first clamping block is movably engaged with the side wall of the first detection block, and one end of the movable block protruding from the second clamping block is movably engaged with the side wall of the second detection block.

[0034] By adopting the above technical solution, when the positions of the first detection block and the second detection block are adjusted to correspond to the positions of the inner wall and the outer wall of the packaging box, the first detection block / the second detection block presses against the movable block, thereby driving the movable block to slide, and then driving the sealing plate to descend to the position to open the coating hole and the negative pressure hole.

[0035] 1. The first detection block is arranged to fit with the inner wall of the packaging box, and the first abutting block is arranged to fit with the outer wall of the packaging box. The first detection block and the first abutting block form a space to enclose the side wall of the packaging box.

By setting the first bevel gear, the second bevel gear, the flow balancing blade and the coating blade, when the water flow impacts the flow balancing blade to rotate, the flow balancing blade drives the adjusting rod to rotate, and the first bevel gear on the adjusting rod drives the coating blade and the second bevel gear on the negative pressure blade shaft to rotate, thereby realizing the rotation drive of the coating blade and the flow balancing blade, so as to continuously coat and absorb the fluorescent powder on the outer peripheral wall and the inner peripheral wall of the packaging box, reduce the input of external power source, and thus reduce the operation steps of relevant technical personnel when performing waterproof performance testing; BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is combined with Figure 1-5 This application is described in further detail.

[0039] The present application embodiment discloses a gift packaging box 15 waterproof performance detection device and detection method. Figure 1A gift box 15 waterproof performance testing device includes a vertically arranged frame 1, a workbench 11 for the box 15 to be placed on is horizontally fixed on the frame 1, a positioning block 12 is provided on the frame 1 in a lifting manner, the positioning block 12 slides and rises along the height direction of the frame 1, the positioning block 12 is movably inserted into the box 15, and the positioning block 12 is consistent with the height direction of the frame 1, the two opposite inner walls of the box 15 that do not need to be tested are in contact, and the positioning block 12 is also provided with an internal testing component 2 for performing an internal waterproof test on the box 15 and an external testing component 3 for performing an external waterproof test on the outer wall of the box 15.

[0040] Reference Figure 1 and Figure 2 The inner detection component 2 includes a first detection block 21 and a first clamping block 22 which are slidably arranged on the positioning block 12. The first detection block 21 and the first clamping block 22 are arranged opposite to each other. The sliding direction of the first detection block 21 and the first clamping block 22 is consistent with the direction of the width of the packaging box 15, and a clamping cavity 23 for clamping the side wall of the packaging box 15 is reserved between the first detection block 21 and the first clamping block 22. A first detection hole 24 is opened on the first detection block 21, and the first detection hole 24 is arranged toward the inner wall of the packaging box 15, and the first detection block 21 is movably fitted with the inner wall of the packaging box 15, and the first clamping block 22 is movably fitted with the outer wall of the packaging box 15.

[0041] At the same time, the external detection component 3 includes a second detection block 31 and a second clamping block 32 which are slidably arranged on the positioning block 12. The second detection block 31 and the second clamping block 32 are also arranged relatively to each other, and a clamping cavity 23 for clamping the side wall of the packaging box 15 is also reserved between the second detection block 31 and the second clamping block 32. A second detection hole 33 is opened on the second detection block 31. The second detection block 31 is arranged toward the outer wall of the packaging box 15, and the second clamping block 32 is arranged toward the inner wall of the packaging box 15.

[0042] A liquid storage tank 25 is provided on the positioning block 12, and a test liquid for waterproof testing of the packaging box 15 is stored in the liquid storage tank 25. In the present application, the test liquid is water, and the liquid storage tank 25 is connected to the first test block 21 and the second test block 31. A power component 26 is also provided on the liquid storage tank 25. In the present application, the power component 26 is a water pump. The power component 26 squeezes the liquid in the liquid storage tank 25 from the first test hole 24 and the second test hole 33, thereby realizing the waterproof performance test of the packaging box 15.

[0043] At the same time, a marking box 4 is provided on the first clamping block 22 and the second clamping block 32, and fluorescent powder is stored in the marking box 4. The first clamping block 22 and the second clamping block 32 are both provided with a coating member 41 for coating the side wall of the packaging box 15 with fluorescent powder, and the first clamping block 22 and the second clamping block 32 are also provided with a camera member 42 for taking an image of the side wall of the packaging box 15.

[0044] Since the waterproof performance of the packaging box 15 is inconsistent under different water flow impact forces during the waterproof test, in order to facilitate the detection of the waterproof performance of the packaging box 15 under different water flow impact forces, the positioning block 12 is provided with a bracket 13 fixedly connected to the first detection block 21 and the second detection block 31, and the bracket 13 is slidably arranged relative to the workbench 11 and the positioning block 12. The power source for slidingly driving the bracket 13 here can be any type of linear power source, and the bracket 13 is provided with a connecting pipe 43 connected to the first detection block 21 and the second detection block 31. An adjusting plate 44 is rotatably connected to the connecting pipe 43, and a gap is left between the adjusting plate 44 and the inner side wall of the connecting pipe 43 for water flow to pass through, and the gap changes with the rotation angle of the adjusting plate 44, and the first clamping block 22 and the second clamping block 32 are also provided with a marking member 45 for marking the side wall of the packaging box 15 according to different water flow impact forces.

[0045] One end of the rotating shaft of the adjusting plate 44 protrudes from the connecting tube 43, and a first adjusting gear 441 is coaxially fixed on the rotating shaft of the adjusting plate 44, and a first adjusting rack 442 is fixedly connected to the positioning block 12, and the first adjusting rack 442 is meshed with the first adjusting gear 441. When the bracket 13 is driven to slide relative to the positioning block 12, the first adjusting rack 442 drives the first adjusting gear 441 to rotate, thereby driving the adjusting plate 44 to rotate, so that in the process of the first detection block 21 and the second detection block 31 moving along the width direction of the packaging box 15, the impact force of the water flow flowing through the first detection hole 24 and the second detection hole 33 in the connecting tube 43 is adjusted, and the impact force of the water flow is automatically adjusted during the movement of the first detection block 21 and the second detection block 31.

[0046] At the same time, since the impact of different water flows needs to be reflected, the precise waterproof performance of the packaging box 15 can be obtained. Therefore, referring to Figure 3 and Figure 4 The marking member 45 includes a marking block 451 slidably set on the first clamping block 22 / the second clamping block 32, the marking block 451 on the first clamping block 22 movably protrudes from the side of the first clamping block 22 close to the outer wall of the packaging box 15, the marking block 451 on the second clamping block 32 movably protrudes from the side of the second clamping block 32 close to the inner wall of the packaging box 15, and the protruding end of the marking block 451 movably fits with the outer wall / inner wall of the packaging box 15.

[0047] The first clamping block 22 and the second clamping block 32 are both provided with a receiving groove 452, and the marking block 451 is elastically slidably arranged in the receiving groove 452. The first clamping block 22 and the second clamping block 32 are both rotatably connected with an adjusting rod 455, and the rotation axis of the adjusting rod 455 is consistent with the height direction of the frame 1, and a plurality of limit blocks 453 are provided on the adjusting rod 455. The end of the marking block 451 on the first clamping block 22 away from the outer wall of the packaging box 15 is fixedly connected with an abutment block 454, and the end of the marking block 451 on the second clamping block 32 away from the inner wall of the packaging box 15 is fixedly connected with the abutment block 454. The end sides of the limit blocks 453 and the abutment blocks 454 that are close to each other are movably fitted, and the end sides of the limit blocks 453 and the abutment blocks 454 that are movably fitted are inclined, and the rotation period of the adjusting rod 455 is consistent with the first inspection The water flow speed in the measuring block 21 is associated with that in the second measuring block 31, so that when the adjusting plate 44 adjusts the water flow in the first measuring block 21 and the second measuring block 31 with the movement of the bracket 13, the rotation period of the adjusting rod 455 is adjusted at this time. When the adjusting rod 455 rotates, it drives multiple limit blocks 453 to rotate. Each time the limit block 453 rotates to a position where the abutment block 454 fits, the limit block 453 drives the abutment block 454 to slide, thereby protruding the marking block 451. At this time, because the bracket 13 always drives the first measuring block 21 and the second measuring block 31 to slide, the marking block 451 marks the side wall of the packaging box 15, and the relevant technical personnel can judge the impact force of the water flow through the distance between two adjacent marking points, and then evaluate the waterproof performance of the subsequent packaging box 15.

[0048] The first detection block 21 and the second detection block 31 are both rotatably provided with flow equalizing blades 457, and the rotation axis of the flow equalizing blades 457 is consistent with the width direction of the packaging box 15. The flow equalizing blades 457 are in contact with the water flow in the first detection block 21 / the second detection block 31, and a third adjusting gear 444 is fixedly connected to the rotating shaft of the flow equalizing blade 457, and a second adjusting gear 443 is coaxially fixed on the adjusting rod 455, and the second adjusting gear 443 is meshed with the third adjusting gear 444, so that when the adjusting plate 44 is adjusted for angle adjustment, as the flow velocity of the water flow changes, when the water flow impacts the flow equalizing blade 457 to rotate, it drives the third adjusting gear 444 to rotate, and the third adjusting gear 444 drives the second adjusting gear 443 to rotate, thereby driving the adjusting rod 455 to rotate, thereby realizing the sliding adjustment of the marking block 451 and realizing the marking of the side wall of the packaging box 15.

[0049] When fluorescent powder coating is required, refer to Figure 4 and Figure 3A coating hole 411 is provided on one side of the first clamping block 22 close to the outer wall of the packaging box 15 and a coating hole 411 is provided on one side of the second clamping block 32 close to the inner wall of the packaging box 15, and the coating hole 411 is communicated with the marking box 4. A negative pressure hole 412 is also provided on one side of the coating hole 411 of the first clamping block 22 and the second clamping block 32, and the negative pressure hole 412 is also communicated with the marking box 4, wherein a coating blade 414 is rotatably arranged in the coating hole 411, and when the coating blade 414 rotates, a positive pressure is generated toward the outside of the coating hole 411, and the fluorescent powder in the marking box 4 is sprayed out from the outside of the coating hole 411, and a negative pressure blade 413 is rotatably arranged in the negative pressure hole 412, and when the negative pressure blade 413 rotates, a negative pressure is generated at the negative pressure hole 412, and the fluorescent powder adhered to the packaging box 15 is sucked into the marking box 4 through the negative pressure hole 412.

[0050] Furthermore, a first bevel gear 415 is coaxially fixed on the adjusting rod 455, and a second bevel gear 416 is coaxially fixed on the rotating shafts of the coating blade 414 and the negative pressure blade 413, and the first bevel gear 415 is meshed with the two second bevel gears 416. Therefore, when the water flow velocity changes, the coating blade 414 and the negative pressure blade 413 are driven to rotate, so as to achieve the coating of the fluorescent powder and the recovery of the excess fluorescent powder. Since the adhesion performance of the packaging box 15 to the powder is significantly enhanced after being wetted, after a part of the excess fluorescent powder is absorbed by the negative pressure blade 413, the distinction between good and poor waterproof performance is obvious in the picture taken by the camera 42, so that it is easy to obtain the waterproof performance of the packaging box 15 under different water flow impact forces.

[0051] At the same time, in order to facilitate the waterproof performance test of the packaging box 15, the first detection block 21 and the first abutting block 22 are arranged to slide relative to each other, and the second detection block 31 and the second abutting block 32 are arranged to slide relative to each other.
