Description

TECHNICAL FIELD

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

[0002] The commonly sold wine and beverage packaging boxes on the market are injection molded packaging boxes. Paper base plates are used as base materials, the outer surfaces of the paper base plates are coated with waterproof materials, and various anti-fake films and plastic films are covered to ensure the appearance and strength performance of the packaging boxes.

[0003] During transportation, the wine and beverage may be damaged to cause leakage, and the product quality in the packaging box may be affected by rain or humidity in the transportation process. Therefore, the packaging box needs to be waterproof detected before product packaging.

[0004] There are three common methods for waterproof detection of packaging boxes, namely visual method, weight method and water pressure method.

[0005] The visual method is to coat the outer surface of the packaging box to be tested with water, and to observe whether water droplets float on the surface of the packaging box and whether the water droplets are absorbed. If the water droplets float and are not absorbed, it indicates that the waterproof performance is good, otherwise the waterproof performance is poor.

[0006] The weight method is to weigh the packaging box to be tested, then coat the surface of the packaging box with water, and weigh again after the water on the surface is fully penetrated. The waterproof performance of the packaging box is determined by comparing the difference between the two weights.

[0007] The water pressure method is to compress and immerse the packaging box to be tested in water, and gradually increase the water pressure to observe whether the packaging box leaks, so as to evaluate the waterproof performance of the packaging box.

[0008] According to the related art, due to the different products in the packaging box and the different transportation environments, the transportation loss and product loss during production and transportation are also different. In addition, the internal waterproof and external waterproof requirements of the packaging box are different according to different products. For example, for fragile wine and beverage, it is necessary to reduce the impact of wine and beverage spill on surrounding packaging boxes. The waterproof performance during transportation is mainly determined by the waterproof performance of the outer packaging box. However, it is not easy to directly judge the internal and external waterproof performance of the packaging box by the above methods, and therefore needs to be improved. SUMMARY

[0009] In order to facilitate the detection of the internal and external waterproof performance of the packaging box, the present application provides a gift packaging box waterproof performance detection equipment and detection method.

[0010] The application provides a gift packaging box waterproof performance detection equipment and detection method which adopts the following technical scheme:

[0012] The inner detection assembly comprises a first detection block and a first abutting block which are 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 left between the first detection block and the first abutting block, a first detection hole is formed in the first detection block, a liquid storage tank is arranged on the rack and is in communication with the first detection block, a power member is arranged in the liquid storage tank, the liquid in the liquid storage tank is extruded out of the first detection hole, and the first detection block is in contact with the inner side wall of the packaging box.

[0013] The outer detection assembly comprises a second detection block and a second abutting block which are slidably arranged on the positioning block, a clamping cavity for clamping the side wall of the packaging box is left between the second detection block and the second abutting block, a second detection hole is formed in the second detection block, the second detection block is also in communication with 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 and the second detection block are in communication.

[0014] The first abutting block and the second abutting block are both provided with a marker tank, the marker tank stores fluorescent powder, the first abutting block and the second abutting block are provided with a coating member for coating the side wall of the packaging box with the fluorescent powder, and the first abutting block and the second abutting block are further provided with a camera member for taking images of the side wall of the packaging box.

[0015] By adopting the above technical scheme, the inner waterproof performance and the outer waterproof performance of the packaging box directly affect the transportation loss during product transportation and the packaging loss during product packaging, and the material and process of the packaging box can be improved according to the transportation loss and the packaging loss, so as to improve the product quality of the packaging box.

[0016] When detecting the waterproof performance of the packaging box, the packaging box is first placed on the workbench, and then the positioning block is inserted into the packaging box to abut and abut the inner bottom wall of the packaging box, so that the packaging box is not easy to shift and shake during subsequent waterproof detection of the packaging box.

[0017] At this time, it should be noted that when the waterproof performance of the packaging box is detected, the packaging box is usually unfolded, and then the permeability of the planar packaging paperboard is detected. However, the folding of the packaging box during use will affect the permeability and waterproofness of the packaging box. Therefore, the waterproof performance of the packaging box is detected after the packaging box is folded to simulate the state of the packaging box during use, so that more accurate waterproof performance results of the packaging box are obtained.

[0018] When the waterproof detection is performed, the first detection block is attached to the inner wall of the packaging box, and the first abutting block is attached to the outer wall of the packaging box. The first detection block and the first abutting block form a space for enclosing the side wall of the packaging box. At this time, the power member sprays the liquid in the liquid storage tank to the inner side wall of the packaging box through the first detection hole, sprays the fluorescent powder to the inner side wall of the packaging box through the first abutting block, and captures the image of the inner wall of the packaging box through the camera member. Since the wetness of the inner wall of the packaging box directly affects the adhesion performance of the packaging box, the waterproof performance of the outer wall of the packaging box can be determined according to the degree and amount of adhesion of the fluorescent powder on the inner wall of the packaging box.

[0019] Meanwhile, the second detection block is attached to the outer wall of the packaging box, and the second abutting block is attached to the inner wall of the packaging box. The second detection block sprays water towards the outer wall of the packaging box, and the second abutting block sprays fluorescent powder towards the inner wall of the packaging box. Thus, the waterproof performance of the inner wall of the packaging box can be determined according to the degree and amount of adhesion of the fluorescent powder on the outer wall of the packaging box.

[0020] After the waterproof performance of the inner wall and the outer wall of the packaging box is obtained through the above scheme, the waterproof performance difference 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 according to the difference.

[0021] Optionally, the liquid storage tank is provided with a connecting pipe in communication with the first detection block and the second detection block.

The first abutting block and the second abutting block are further provided with a marking member for marking the side wall of the packaging box according to the water flow impact force at the first detection hole and the second detection hole.

[0022] By adopting the above technical scheme, the area through which the water flow passes in the connecting pipe is adjusted by the adjusting plate. Since the power member is a water pump, the water flow into the connecting pipe is fixed. When the water flow in the connecting pipe passes through the connecting pipe, the water flow speed will also change, so that the water flow impact force at the first detection hole and the second detection hole is changed, and then the waterproof performance of the packaging box under different impact forces can be determined according to the change of the water flow speed.

[0023] Meanwhile, the marking member is arranged, so that when the water flow impact force changes, the packaging box is marked, thereby facilitating the water flow speed change as a base point when subsequent photographing, the water flow speed change is judged, and the water flow impact force change is judged.

[0024] Optionally, the rotating shaft of the adjusting plate is provided with a first adjusting gear, and the positioning block is provided with a first adjusting rack, and the first adjusting gear is engaged with the first adjusting rack.

[0025] By adopting the above technical scheme, when the first detection block and the second detection block are driven to slide, the first adjusting rack does not slide, and the first adjusting gear is driven to rotate by the first adjusting rack, so that the rotating drive of the adjusting plate is realized, the area through which the water flow passes in the connecting pipe is adjusted, and the water flow impact at the first detection hole and the second detection hole is adjusted.

[0026] Optionally, the marking member comprises a marking block slidingly arranged on the first abutting block / second abutting block, the marking block is movably protruded from the first abutting block / second abutting block, the first abutting block and the second abutting block are both provided with a receiving groove, the marking block is elastically slidingly arranged in the receiving groove, the first abutting block and the second abutting block are both rotatably connected with a second adjusting rod, the second adjusting rod is provided with a plurality of limiting blocks, the marking block is provided with an abutting block, the limiting blocks and the abutting block are movably attached, and the end side of the limiting blocks and the abutting block movably attached 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 a flow equalizing vane, and the flow equalizing vane is synchronously rotated with the second adjusting gear.

[0027] By adopting the above technical scheme, when the adjusting plate rotates to adjust the area through which the water flow passes in the connecting pipe, the water flow speed in the first detection block and the second detection block changes at this time, so that the water flow speed impacting the flow equalizing vane changes, when the flow equalizing vane rotates, the second adjusting gear is synchronously rotated, the second adjusting rod also rotates one cycle for each cycle of the adjusting gear, that is, the plurality of limiting blocks are sequentially attached to the abutting block, and the abutting block is protruded under the action of the limiting block and the elastic restoring force, so as to protrude the marking block from the first abutting block / second abutting block, and the marking block marks the inner side wall or the outer side wall of the packaging box, thereby facilitating the judgment of the rotating speed of the flow equalizing vane according to the change of the distance between the adjacent two marking points by the camera member in the subsequent time, and the waterproof performance of the packaging box under different water flow speeds is judged.

[0028] Optionally, the first abutting block is provided with a coating hole near one side of the outer side wall of the packaging box, and the second abutting block is provided with a coating hole near one side of the inner side wall of the packaging box, the coating holes are in communication with the marking box, the first abutting block and the second abutting block are provided with negative pressure holes, the negative pressure holes are rotatably provided with negative pressure vanes, and the coating holes are rotatably provided with coating vanes.

[0029] By adopting the above technical scheme, when the water flow impacts the flow equalizing vane to rotate and drives the second adjusting gear and the adjusting rod to rotate, the negative pressure vane and the coating vane are driven to rotate when the adjusting rod rotates, so that the fluorescent powder in the marking box is squeezed out through the coating hole, and the outer side wall and the inner side wall of the packaging box are coated with fluorescent powder. The rotation of the negative pressure vane causes negative pressure in the negative pressure hole, so that the excess fluorescent powder on the outer side wall and the inner side wall of the packaging box is absorbed. The fluorescent powder that is not absorbed is more likely to accurately reflect the waterproof performance of the packaging box, so that relevant personnel can accurately judge the waterproof performance of the packaging box under different water flow and water pressure.

[0033] By adopting the above technical scheme, when the waterproof performance of the packaging box needs to be detected, the support is only needed to be slid by the driving piece, so as to realize the synchronous sliding of the first detection block and the second detection block, and realize the driving in the width direction of the packaging box.

[0036] Meanwhile, during the waterproof performance detection of the first detection block and the second detection block, when the detection is completed, the coating hole and the negative pressure hole need to be plugged, so as to reduce the waste of fluorescent powder. Therefore, the plugging member is arranged to plug the coating hole and the negative pressure hole, so as to realize the saving of fluorescent powder and reduce the waste of resources.

[0037] Optionally, the plugging member comprises a plugging plate slidably arranged on the first abutting block / second abutting block, the plugging plate is liftably arranged on the first abutting block / second abutting block, and the first abutting block / second abutting block is slidably provided with a movable block, the movable block protrudes from the first abutting block / second abutting block, one end of the movable block protruding from the first abutting block is movably attached to the side wall of the first detection block, and one end of the movable block protruding from the second abutting block is movably attached to the side wall of the second detection block.

[0053] Because the waterproof performance of the packaging box 15 is not consistent under different water flow impact forces when waterproof detection is performed, 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 support 13 fixedly connected with the first detection block 21 and the second detection block 31, the support 13 is slidingly arranged relative to the workbench 11 and the positioning block 12, the power source for driving the support 13 to slide can be any one of the linear power sources, the support 13 is provided with a connecting pipe 43 in communication with the first detection block 21 and the second detection block 31, the connecting pipe 43 is rotatably connected with an adjusting plate 44, a gap for water flow is left between the adjusting plate 44 and the inner side wall of the connecting pipe 43, the gap changes with the rotation angle of the adjusting plate 44, and the first abutting block 22 and the second abutting 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.

[0054] One end of the rotating shaft of the adjusting plate 44 protrudes out of the connecting pipe 43, and a first adjusting gear 441 is coaxially fixed on the rotating shaft of the adjusting plate 44, and the positioning block 12 is fixedly connected with a first adjusting gear 442, the first adjusting gear 442 is engaged with the first adjusting gear 441, when the support 13 is driven to slide relative to the positioning block 12, the first adjusting gear 442 drives the first adjusting gear 441 to rotate, thereby driving the adjusting plate 44 to rotate, thereby adjusting the water flow impact force at the first detection hole 24 and the second detection hole 33 in the connecting pipe 43 during the movement of the first detection block 21 and the second detection block 31 along the width direction of the packaging box 15, and the water flow impact force is automatically adjusted during the movement of the first detection block 21 and the second detection block 31.

[0055] Meanwhile, because different water flow impact forces need to be reflected, the waterproof performance of the packaging box 15 is accurate, therefore, referring to Figure 3 and Figure 4 , the marking member 45 includes a marking block 451 slidingly arranged on the first abutting block 22 / second abutting block 32, the marking block 451 on the first abutting block 22 protrudes from the side of the first abutting block 22 close to the outer side wall of the packaging box 15, the marking block 451 on the second abutting block 32 protrudes from the side of the second abutting block 32 close to the inner side wall of the packaging box 15, and the protruding end of the marking block 451 is movably attached to the outer side wall / inner side wall of the packaging box 15.

[0056] And the first abutting block 22 and the second abutting block 32 are provided with accommodating grooves 452, and the marker block 451 is elastically and slidably arranged in the accommodating grooves 452. The first abutting block 22 and the second abutting block 32 are rotatably connected with the adjusting rod 455, the rotation axis of the adjusting rod 455 is consistent with the height direction of the rack 1, and a plurality of limiting blocks 453 are arranged on the adjusting rod 455. One end of the marker block 451 away from the outer side wall of the packaging box 15 is fixedly connected with the abutting block 454 on the first abutting block 22. One end of the marker block 451 away from the inner side wall of the packaging box 15 is fixedly connected with the abutting block 454 on the second abutting block 32. The end sides of the limiting blocks 453 and the abutting blocks 454 close to each other are movably attached, the end sides of the limiting blocks 453 and the abutting blocks 454 movably attached are inclined, and the rotation period of the adjusting rod 455 is associated with the water flow speed in the first detection block 21 and the second detection block 31. Therefore, when the adjusting plate 44 adjusts the water flow in the first detection block 21 and the second detection block 31 with the movement of the support 13, the rotation period of the adjusting rod 455 is adjusted. When the adjusting rod 455 rotates, the plurality of limiting blocks 453 are driven to rotate. When the limiting block 453 rotates to the position where the abutting block 454 is attached each time, the limiting block 453 drives the abutting block 454 to slide at this time, so that the marker block 451 protrudes. Since the support 13 always drives the first detection block 21 and the second detection block 31 to slide at this time, the marker block 451 marks the side wall of the packaging box 15. The related technical personnel can determine the water flow impact force according to the spacing between the adjacent two marker points, and then evaluate the waterproof performance of the subsequent packaging box 15.

[0057] The first detection block 21 and the second detection block 31 are rotatably provided with flow uniforming vanes 457, the rotation axis of the flow uniforming vanes 457 is consistent with the width direction of the packaging box 15, the flow uniforming vanes 457 are attached with the water flow in the first detection block 21 / second detection block 31, and the rotation shaft of the flow uniforming vanes 457 is fixedly connected with the third adjusting gear 444.

When the water flow impacts the flow uniforming vanes 457 to rotate, the third adjusting gear 444 is driven to rotate, the third adjusting gear 444 drives the second adjusting gear 443 to rotate, thereby driving the adjusting rod 455 to rotate, and the sliding adjustment of the marker block 451 is realized, and the marking of the side wall of the packaging box 15 is realized.

[0058] When the fluorescent powder needs to be coated, refer to Figure 4 and Figure 3The first abutting block 22 is close to one side of the outer side wall of the packaging box 15, the second abutting block 32 is close to one side of the inner side wall of the packaging box 15, and a coating hole 411 is formed in the first abutting block 22 and the second abutting block 32, and the coating hole 411 is in communication with the marking box 4. The first abutting block 22 and the second abutting block 32 are provided with a negative pressure hole 412 on one side of the coating hole 411, and the negative pressure hole 412 is also in communication with the marking box 4. A coating blade 414 is rotatably arranged in the coating hole 411, and when the coating blade 414 rotates, a positive pressure is generated on the outer side of the coating hole 411, so that the fluorescent powder in the marking box 4 is sprayed out of the coating hole 411. 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, so that the fluorescent powder adhered on the packaging box 15 is sucked into the marking box 4 through the negative pressure hole 412.

[0059] Furthermore, a first bevel gear 415 is coaxially fixed on the adjusting rod 455, a second bevel gear 416 is coaxially fixed on the rotating shaft of the coating blade 414 and the negative pressure blade 413, and the first bevel gear 415 is engaged with the two second bevel gears 416. When the water flow speed changes, the coating blade 414 and the negative pressure blade 413 are driven to rotate, so that the coating of the fluorescent powder and the recycling of the excess fluorescent powder are realized.
