Description

Technical Field

[0001] The present invention relates to the technical field of shoe upper water permeability testing, and more particularly to a shoe upper waterproof testing device. Background Art

[0002] The upper water permeability test is a core testing method for evaluating the waterproof performance of footwear products. Its core value lies in simulating extreme environmental conditions such as rain, snow, and humidity to verify the upper material's ability to block external water penetration, thereby ensuring the wearer's feet remain dry and comfortable in complex climates. This testing system covers four major dimensions: static water pressure testing, water absorption testing, hydrophobicity testing, and immersion testing. The static water pressure test has attracted much attention due to its direct correlation with the material's water pressure resistance.

[0003] The current standard testing process for static water pressure testing technology is divided into four steps: 1. Fixing the upper sample in a standardized manner at the test station to ensure that the water injection area is covered; 2. Pressure loading: Apply continuous water pressure on one side of the upper through the water injection system, and the test environment must meet standard atmospheric conditions; 3. Failure judgment: Continue to increase the pressure until three water seepage points appear on the surface of the sample, and record the instantaneous pressure value generated at the third water seepage point; 4. Performance evaluation: Use the critical pressure value as a quantitative indicator of waterproof performance. The higher the value, the better the waterproof performance.

[0004] However, actual measurements have verified that traditional testing devices have a systematic error source. The reason is that after the sample is fixed, the air layer remaining between the sample and the liquid surface forms an elastic air cushion during the continuous pressurization process. The air cushion area produces a pressure buffering effect, resulting in the actual water pressure acting on the material surface being lower than the value displayed by the equipment. This phenomenon causes the critical water seepage pressure value of the material to be overestimated, resulting in distorted evaluation of the waterproof performance.

[0005] As for the problem of air layer, the current main method is to pre-fix the shoe upper and then inject water during the tooling fixation process. As the liquid level rises, the internal air will be concentrated under the shoe upper. The staff then manually squeeze the shoe upper to expel the air. After confirming that the air is expelled, it will be completely fixed. Although this method can expel the air to a certain extent, the operation is relatively cumbersome and complicated.

[0006] Therefore, new solutions need to be proposed to solve this problem. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a shoe upper waterproof detection device in order to solve the above problems.

[0008] The present invention achieves the above-mentioned object through the following technical solutions: a shoe upper waterproof detection device, comprising a base, a water injection station and an upper press head, wherein a water injection port is provided on the side wall of the water injection station, and the water injection port is configured as a tangential inlet, an exhaust column is fixedly provided at the center of the water injection station, the top height of the exhaust column is flush with the horizontal height of the detection object placement surface corresponding to the water injection station, the bottom of the exhaust column is connected to an exhaust pipe, and an induction opening and closing component is provided in the exhaust pipe; When the water injection port injects water into the water injection station, the water flow is induced to rotate to form a vortex, so that the air gathers toward the center and is discharged through the exhaust column.

[0009] The present invention is further configured as follows: a plurality of air guide holes 1 are opened on the side wall of the exhaust column, the air guide holes 1 are evenly arranged around the periphery of the exhaust column to form a layered arrangement, and the distribution density of the air guide holes 1 distributed at different levels increases from the bottom to the top of the exhaust column.

The two ends of the elastic member 1 are respectively connected to the sealing member and the air guide hole 2. A support frame is fixedly provided in the air guide hole 2 for connecting the elastic member 1.

[0011] The present invention is further configured as follows: the secondary exhaust assembly further comprises a housing, the housing being slidably disposed on the exhaust column, a pre-pressing assembly being further disposed between the exhaust column and the housing, the pre-pressing assembly comprising: A pre-stressed spring element is used to push the shell to slide toward the top of the exhaust column, with both ends of the pre-stressed spring element abutting against the exhaust column and the shell respectively; A clamping member is detachably connected to the housing, wherein the clamping member is slidably disposed on the exhaust column, and one end of the clamping member extends to the outside of the exhaust column; The magnetic member forms an adsorption force with the clamping member to limit the clamping member from sliding into the exhaust column. The magnetic member is fixedly connected to the exhaust column.

[0012] The present invention is further configured as follows: one end of the exhaust pipe is embedded in the shell and communicated with the second air guide hole, and an air intake channel communicating with the second air guide hole and the first air guide hole is further opened on the side wall of the shell.

[0013] The present invention is further configured as follows: an annular abutment is fixedly connected to the abutment portion between the upper pressing head and the detection object, and an annular tension ring assembly is provided on the side wall of the annular abutment to ensure that the center position of the detection object always maintains a slight dome shape during the water injection process. The annular tension ring assembly includes: Fixed bracket, fixedly connected to the inner side of the annular abutment: The rotating member is used to push the detection object to form a slight dome shape. The connection between the fixed frame and the rotating member is fixedly connected to a guide member, and the rotating member is rotatably sleeved on the outside of the guide member. A transmission member is slidably disposed on the fixed frame, and the transmission member is in transmission connection with the rotating member; A driving member is in transmission connection with the transmission member, wherein the driving member is disposed on the fixing frame and has an end away from the transmission member extending to the outside of the fixing frame; The water injection station is fixedly provided with an abutment portion for abutting the extended end of the driving member. When the upper pressing head is pressed down, the abutment portion abuts against the driving member and pushes the driving member to apply external force so that the driving member drives the transmission member to slide.

[0014] The present invention is further configured as follows: a pre-fixing assembly is further provided on the annular abutment member, and the pre-fixing assembly includes: An annular abutting piece, used for abutting against the detection object, wherein the annular abutting piece is slidably connected to the annular abutting member; The elastic member 2 has two ends respectively abutting against the annular abutting sheet and the annular abutting member.

[0015] The present invention is further configured as follows: a plurality of water injection ports are provided, which are evenly arranged around the inner wall of the water injection station, and the plurality of water injection ports form a layered water injection structure.

[0018] Compared with the prior art, the present invention has the following beneficial effects: First, the tangential water inlet design induces water flow to form a vortex, using centrifugal force to gather air to the central exhaust column. Combined with the layered air guide holes, a stepped exhaust is formed, achieving step-by-step gas capture and improving exhaust efficiency. When the water level reaches the highest air guide hole, the water pressure triggers the pre-load assembly to release the shell, and the spring pushes the secondary exhaust assembly upward to the air gathering area. At the same time, the air pressure compresses the seal to open the second air guide hole, ensuring that any remaining air at the top is completely discharged. Secondly, the flow sensor is linked with the solenoid valve to monitor the water flow in the exhaust pipe in real time. If the threshold is exceeded, the exhaust channel will be automatically closed to form a closed water injection environment, avoiding manual intervention errors. Third, the annular tension ring assembly driven by the rotating part dynamically adjusts the curvature of the test object through a cam mechanism, forming a central high-rigidity dome shape, dispersing the impact and vibration energy of the water flow and preventing air entrapment caused by collapse and wrinkles. The elastic pre-loaded annular abutment piece preferentially contacts the shoe surface and cooperates with the guide rod to form a pre-fixation, ensuring that outside air cannot penetrate during the dome forming process, thereby improving the consistency of detection. Fourth, the water injection speed decreases from the bottom layer to the middle layer and then to the top layer, matching the pressure release rhythm to avoid turbulent air entrainment; the water injection angle increases layer by layer, coordinating with the swirl intensity to stabilize the air guide path; Fifth, through the coordinated control of swirl, air pressure, elastic deformation and mechatronic control, the accuracy, efficiency and automation level of waterproof detection are significantly improved, which is suitable for high-precision shoe upper waterproof quality inspection scenarios.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0022] A shoe upper waterproof detection device, such as Figures 1-9 As shown, it includes a base 1, a water injection station 2 and an upper press head 3, wherein the base 1 is also provided with a water injection system (not shown) connected to the water injection station 2, and the water injection system includes a water pump and a water guide channel to achieve a water supply effect for the water injection station 2, and the base 1 is also provided with an indicator meter showing the water pressure inside the water injection station 2.

[0023] like Figure 1 、 Figure 2 and Figure 4 As shown, a water inlet 4 is provided on the side wall of the water filling station 2. The water inlet 4 is configured as a tangential inlet to induce water flow to rotate and form a vortex, causing air to gather toward the center. An exhaust column 5 is fixed at the center of the water filling station 2. The bottom of the exhaust column 5 is connected to an exhaust pipe 6, so that air can be guided to the outside through the cooperation between the exhaust column 5 and the exhaust pipe 6. At the same time, the height of the top of the exhaust column 5 is flush with the horizontal height of the test object placement surface corresponding to the water filling station 2, so that the exhaust column 5 is in contact with the liquid level when it is fully filled with water, ensuring the exhaust effect.

[0024] like Figure 4 As shown, an inductive opening and closing component is provided in the exhaust pipe 6, which includes a flow sensor and a solenoid valve 25. When the water filling station 2 is filled with water, the water flow will enter the exhaust pipe 6, and the flow rate of the water in the exhaust pipe 6 is measured by the flow sensor. When the flow rate exceeds the set threshold, a closing signal is triggered and transmitted to the solenoid valve 25. The exhaust pipe 6 is closed by the solenoid valve 25, so that the water filling station 2 is in a closed state, thereby facilitating the subsequent increase in water pressure.

[0025] like Figure 1 、 Figure 2 and Figure 4As shown, a number of air guide holes 7 are opened on the side wall of the exhaust column 5. The air guide holes 7 are evenly arranged around the outer periphery of the exhaust column 5 and are connected to the exhaust pipe 6 through the air guide holes 7, thereby achieving an exhaust effect and forming a layered arrangement. When the water level rises through the layered arrangement, after the lower air guide holes 7 are submerged by water, the gas automatically enters the exhaust column 5 through the higher air guide holes 7, forming a stepped exhaust, thereby ensuring the exhaust efficiency, and the distribution density of the air guide holes 7 distributed at different levels increases from the bottom to the top of the exhaust column 5, thereby improving the gas capture probability.

[0026] Among them Figure 4-Figure 5 As shown, a secondary exhaust assembly is provided on the top of the exhaust column 5, and the secondary exhaust assembly includes an air guide hole 2 8 connected to the exhaust pipe 6, a seal 9 for blocking the communication between the air guide hole 2 8 and the outside of the exhaust column 5, and an elastic member 10 for the seal 9 to maintain a sealed state, wherein the air guide hole 2 8 is opened at the top of the exhaust column 5, the seal 9 is slidably set in the air guide hole 2 8, and the two ends of the elastic member 10 are respectively connected to the seal 9 and the air guide hole 2 8, and a support frame 11 is fixedly provided in the air guide hole 2 8 for connecting the elastic member 10, so that when the water level is flush with the horizontal height of the air guide hole 1 7 on the highest layer of the exhaust column 5, the air guide holes 1 7 on the side walls of the exhaust column 5 form a liquid sealing effect. At this time, the air above the top of the exhaust column 5 is in a compressed state, and the air pressure is greater than the elastic thrust of the elastic member 10, thereby pushing the seal 9 to slide, opening the air guide hole 2 8, and then the air above the top of the exhaust column 5 is discharged through the air guide hole 2 8.

[0027] And as Figure 4-Figure 6As shown, the secondary exhaust component also includes a shell 12, which is slidably arranged on the exhaust column 5, and a pre-stressing component is also arranged between the exhaust column 5 and the shell 12. The pre-stressing component includes a pre-stressing spring 13 for pushing the shell 12 to slide toward the top of the exhaust column 5, a clamping member 14 detachably connected to the shell 12, and a magnetic attraction member 15 that forms an adsorption force with the clamping member 14. In the initial state, the clamping member 14 fixes the position of the shell 12 so that the exhaust column 5 is flush with the shell 12, wherein the two ends of the pre-stressing spring 13 are respectively abutted against the exhaust column 5 and the shell 12, and the pre-stressing spring 13 is in a compressed state. The clip 14 is slidably set on the exhaust column 5, and one end of the clip 14 extends to the outside of the exhaust column 5, and the magnetic part 15 is fixedly connected to the exhaust column 5, so that when the internal position of the water injection station 2 rises, the water pressure formed by the corresponding clip 14 also gradually increases. The water pressure on the clip 14 is greater than the adsorption force formed by the magnetic part 15, and then the water pressure pushes the clip 14 to move, and the clip 14 releases the position restriction on the shell 12. The pre-stressed spring 13 pushes the shell 12 to move upward, so that the air guide hole 2 8 of the secondary exhaust component extends into the top air gathering area, thereby completely fitting the bottom surface of the shoe upper to ensure the exhaust effect, and a maximum stroke block of the shell 12 is set in the exhaust column 5 to prevent excessive upward movement from damaging the air guide hole 2 8. At the same time, when the water pressure is reduced during drainage, the user can push the shell 12 back to its original position by pressing.

[0028] like Figure 1-Figure 3 As shown, the upper pressing head 3 includes a threaded rod and an annular abutment 16 fixedly connected to the abutment point with the detection object, wherein the threaded rod is threadedly connected to the base 1 and is connected to the annular abutment 16 so that the rotating threaded rod can drive the annular abutment 16 to move up and down.

[0029] like Figure 3 As shown, an annular tension ring assembly is provided on the side wall of the annular abutment member 16 to ensure that the center position of the detection object always maintains a slight dome shape during the water injection process, wherein the curvature radius of the slight dome shape is 1.5-2.0 times the diameter of the water injection station 2, and is dynamically adjusted according to the elastic modulus of the detection object material, thereby forming a good support effect to avoid collapse or wrinkles causing air retention, and at the same time, a centripetal force can be formed to force the air to move along the dome surface to the highest point, and the impact of water flow during the water injection process may cause vibration of the flexible top. The micro-dome shape can disperse the vibration energy through the structural stiffness distribution (high in the center and low at the edge) to avoid local resonance causing secondary dispersion of air.

[0030] Among them Figure 3As shown, the annular tension ring assembly includes a fixed frame 17 fixedly connected to the inner side of the annular abutment member 16, a rotating member 18 for pushing the detection object to form a slight dome shape, a transmission member 20 slidably set on the fixed frame 17, and a driving member 21 connected to the transmission member 20. A guide member 19 is fixedly connected to the connection between the fixed frame 17 and the rotating member 18, wherein the rotating member 18 is set to a split structure, so as to facilitate the overall installation and setting after production. The rotating member 18 is rotatably sleeved on the outside of the guide member 19, and the rotating member 18 is set to a cam structure so that the rotating member 18 is downward. During movement, the rotating member 18 may first form an abutment with the detection object and push the detection object to form a slight dome shape. The transmission member 20 is connected to the rotating member 18 for transmission. The driving member 21 is arranged on the fixed frame 17, and one end away from the transmission member 20 extends to the outside of the fixed frame 17. At the same time, an abutment portion 22 for abutting the extended end of the driving member 21 is fixedly provided on the water injection station 2. When the upper pressing head 3 is pressed down, the abutment portion 22 abuts against the driving member 21 and pushes the driving member 21 to apply external force, so that the driving member 21 drives the transmission member 20 to slide, and then drives the rotating member 18 to rotate.

[0031] Among them Figure 7 As shown, the driving member 21 is set as a rope structure, and then one end used to abut against the abutting portion 22 is fixedly connected with an abutting block, so that after the abutting portion 22 abuts against the abutting block, the abutting portion 22 and the abutting block are clamped together, thereby driving the transmission member 20 to slide by pulling the driving member 21.

[0032] Among them Figure 8-Figure 9 As shown, a through slot is provided on the guide member 19, and a plurality of push rods are fixedly provided on the side of the transmission member 20 close to the through slot, wherein a guide slot is provided on the inner wall of the rotating member 18 which is in contact with the through slot, and the guide slot is inclined. When the transmission member 20 slides, the push rod on the transmission member 20 is embedded in the guide slot through the through slot and abuts against the side wall of the guide slot, thereby pushing the rotating member 18 to rotate.

[0033] like Figure 1-Figure 3 As shown, a pre-fixing component is also provided on the annular abutment 16, and the pre-fixing component includes an annular abutment piece 23 for abutting the detection object and an elastic member 24 with two ends respectively abutting the annular abutment piece 23 and the annular abutment 16, wherein the annular abutment piece 23 is fixedly connected to a guide rod embedded in the annular abutment 16, and the guide rod is slidingly connected to the annular abutment 16, so that when the annular abutment 16 moves downward, the annular abutment piece 23 will first abut against the shoe upper to form a pre-fixation, wherein the annular abutment piece 23 abuts against the shoe upper before the rotating member 18, thereby preventing outside air from entering when the detection object forms a slight dome shape.

[0034] like Figure 1-Figure 2As shown, several water inlets 4 are provided, evenly distributed around the inner wall of the water injection station 2. These inlets 4 form a layered water injection structure, where the water injection rate decreases layer by layer from bottom layer to middle layer to top layer. This prevents high-speed water from directly impacting the top layer and forming turbulence. This reduces the probability of air being entrained by the water flow by more than 30%, preventing air from mixing with the water and becoming difficult to expel. Furthermore, by filling the space in stages, a sudden increase in air pressure at the top of the exhaust column 5 caused by a single water injection is avoided. For example, a 10-second interval is allowed between each water injection layer, allowing the air pressure to be gradually released through the exhaust column 5.

[0035] At the same time Figure 1 、 Figure 2 and Figure 4 As shown, the layered water injection structure is provided with three layers, and the injection angle of the water injection port 4 of each layer increases successively from the top to the bottom of the exhaust column 5, with the top layer being 20°, the middle layer being 25°, and the bottom layer being 30°, thereby forming a gradient swirl intensity, avoiding the centrifugal dispersion of air caused by a single high-speed swirl, and instead guiding the air stably to the central exhaust column 5 through coordinated swirl, reducing turbulence and matching the rhythm of air pressure release.

[0036] The water injection port 4 is configured as a porous pipe structure to evenly disperse the water flow, avoid air retention in local high-pressure areas, reduce the risk of air being trapped, and ensure exhaust effect.

[0037] The elastic member 10 is a compression spring, and the elastic member 2 24 is a rubber buffer pad. By selecting different materials, the elastic member 10 and the elastic member 2 24 are given good elasticity and are better suitable for their own usage scenarios.

[0038] Working principle: After the staff lays the shoe upper smoothly on the water injection station 2, they start the upper pressing head 3, causing the annular abutment 16 to move downward, and then the annular abutment plate 23 first abuts against the shoe upper to form a pre-fix, and then the rotating member 18 also abuts against the shoe upper, and then the annular abutment 16 moves further downward, and then the abutment portion 22 abuts against the driving member 21, and pushes the driving member 21 to apply external force, and the driving member 21 drives the transmission member 20 to slide. During the sliding process of the transmission member 20, it is connected to the rotating member 18, and then the rotating member 18 pushes the shoe upper to form a slight dome shape, and then the water injection port 4 starts to inject water. Through the tangential inlet design, the water flow is induced to rotate to form a vortex, so that the air gathers towards the center. At the same time, the slight dome shape can form centripetal force, forcing the air to move along the dome surface to the highest point, so that the air converges to the exhaust column 5, and the exhaust effect is achieved through the cooperation of the air guide hole 7 on the exhaust column 5 and the exhaust pipe 6.

[0039] When the water level reaches the highest air guide hole 7, the water pressure on the clamping part 14 is greater than the adsorption force formed by the magnetic part 15, and the water pressure pushes the clamping part 14 to move. The clamping part 14 releases the position restriction on the shell 12, and the pre-stressed spring 13 pushes the shell 12 to move upward, so that the air guide hole 2 8 of the secondary exhaust component extends into the top air gathering area. At the same time, the air guide hole 17 is misaligned with the air intake channel opened on the shell 12, so that the air guide hole 17 is in a closed state. As the water level continues to rise, the air pressure at the air guide hole 2 8 increases, pushing the sealing part 9 to slide inward, and then opening the air guide hole 2 8, so that the remaining air is guided to the exhaust pipe 6 through the air guide hole 2 8 and discharged.

[0040] As the gas is completely discharged, water flows into the exhaust pipe 6. The flow rate of water in the exhaust pipe 6 is measured by the flow sensor. When the flow rate exceeds the set threshold, a closing signal is triggered and transmitted to the solenoid valve 25, and the solenoid valve 25 closes the exhaust pipe 6.

[0041] Continuous water pressure is then applied to one side of the shoe upper through a water injection system to test its waterproof performance.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
