Description

Technical Field

[0001] The present invention relates to the technical field of detection, and specifically to a detection device for waterborne polyurethane coating resin. Background Technique

[0002] Since the advent of waterborne polyurethane in the 1940s, it has experienced technological iterations from simple emulsions to high-performance resins. Early detection mainly relied on basic physical property tests (such as hardness testers and tensile testing machines). However, as the materials develop towards high solid content, low VOC, and functionalization, the detection requirements gradually extend to microscopic levels such as molecular structure analysis and crosslinking density analysis. In recent years, breakthroughs in online monitoring systems, tomography techniques, and machine vision algorithms have increased the detection efficiency by dozens of times and enabled the identification of micron-level defects, promoting the penetration of waterborne polyurethane into high-end application fields. Its technological evolution reflects the deep integration trend of materials science, environmental engineering, and information technology.

[0003] In the existing detection device for waterborne polyurethane coating resin, when using an X-ray machine to detect samples, after each sample plate is inspected, workers need to manually take out the old sample plate from the machine and then put in a new sample plate. Operating in close proximity to the X-ray machine so frequently, the time for workers to be irradiated by radiation becomes longer, which is likely to affect the physical health of workers.

[0015] The present invention has the following beneficial effects: 1. The detection equipment of waterborne polyurethane coating resin realizes batch automatic detection of sample plates by rotating toothed discs, servo motors and hydraulic rods. The ring-shaped mounting toothed discs can fix multiple sample plates, which can reduce the time workers are in contact with the X-ray machine. At the same time, the servo motor accurately controls the rotation angle, and the fixed tube support ensures stable positioning, so that each sample plate is aligned with the irradiation head and the imaging plate in turn to complete the detection; the hydraulic rod drives the driving plate and the resisting plate to realize the vertical and stable movement of the sample, avoiding vibration interference, while improving the detection efficiency and accuracy, and ensuring data consistency.

[0016] 2. The detection equipment of the waterborne polyurethane coating resin realizes automatic identification and stable clamping through mechanical linkage and elastic reset design. When the driving plate drives the sliding fixed block to move down for detection, the resistance rod in the sliding rod is triggered by the groove to move horizontally, driving the triangular resistance block to make the marker at the end of the sliding rod mark, and synchronously completes the detection and multi-color identification. Through the design of multi-color identification, each device can distinguish each sample plate after releasing the clamping of the sample plate, so as to prevent confusion between sample plates. After the detection, the technical solution can unload the samples uniformly without the need to remove the samples one by one manually, which greatly improves the detection effect. Through the design of multi-color identification, the samples can be distinguished according to the different colors after unloading, and the samples are not easily confused, which improves the detection accuracy.

[0017] 3. The detection equipment of the waterborne polyurethane coating resin realizes fully automatic synchronous unloading through a multi-stage linkage mechanism and a coordinated trigger design. When the detection is completed, the servo motor reverses to drive the installed gear disc to rotate, and the driving plate contacts the abutment inclined block and pushes the sliding abutment bar to move laterally, triggering the abutment blocks on all the sliding fixed blocks to be linked in sequence, so that each abutted plate moves downward synchronously; the sliding rod compresses the fifth spring under the abutment of the convex block and drives the clamping block to release the sample plate, so that all samples slide automatically, and the unloading process does not require manual intervention; after unloading, the hydraulic rod resets, the elastic spring drives the sliding fixed block to return to its position, and the first spring ensures the reset of the sliding rod, which is convenient for clamping the next sample plate, further reducing the subsequent labor cost.

Detailed Description of the Invention

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1. Please refer to Figures 1 - 10 The present invention discloses a detection device for waterborne polyurethane coating resin, including a support table 1. Above the support table 1, there is an irradiation head 11 for detecting a sample plate 4. On one side of the irradiation head 11, there is an imaging plate 12. The irradiation head 11 is an X-ray emission source. Through the cooperation of the irradiation head 11 and the imaging plate 12, the sample on the sample plate 4 can be detected. Above the support table 1, there is a fixing plate 15. Below the fixing plate 15, there is an installation gear disc 16. Below the installation gear disc 16, there are a plurality of fixing frames 2. A sliding fixing block 22 is slidably connected to the fixing frames 2. Through the design of the plurality of fixing frames 2 and the sliding fixing block 22, the device can install multiple sample plates 4 at one time, reducing the subsequent frequent replacement of the sample plates 4 by workers. A sliding rod 3 is slidably connected inside the sliding fixing block 22. Inside the lower end of the sliding rod 3, a sliding rod 34 is slidably connected. The lower end of the sliding rod 34 is fixedly connected with a marking pen 35. Through the design of the marking pen 35, after the detection of the sample plate 4 is completed, the sample plate 4 can be marked, enabling the distinction between each sample plate 4. At the same time, the marking pens 35 on each sliding fixing block 22 can use different colors, facilitating the subsequent distinction of the sample plates 4.

[0031] The lower side of the top end of the support table 1 is fixedly connected with a hydraulic rod 13. The hydraulic column of the hydraulic rod 13 passes through the fixing plate 15. The power output end of the hydraulic rod 13 is fixedly connected with a driving plate 19. The upper side of the installation gear disc 16 is rotatably connected with a fixing pipe 14. The other end of the fixing pipe 14 is fixedly connected with the lower side of the fixing plate 15. Through the design of the fixing pipe 14, the subsequent rotation of the installation gear disc 16 can be more stable, providing stable support for the installation gear disc 16 and preventing the occurrence of offset and jitter during the rotation of the installation gear disc 16.

[0032] A servo motor 17 is fixedly installed on the lower side of the fixing plate 15. The power output end of the servo motor 17 is fixedly installed with a driving gear 18. The driving gear 18 is used for meshing connection with the installation gear disc 16. Through the design of the servo motor 17, the driving gear 18 can drive the installation gear disc 16 to rotate, enabling the installation gear disc 16 to drive the fixing frames 2 and the sliding fixing blocks 22 to move, so that the irradiation head 11 can sequentially detect each sample plate 4.

[0033] It should be noted that, through the design of the servo motor 17, the power output can be more controllable, so that the mounting gear plate 16 can be rotated to a required angle, preventing the problem of excessive rotation or too small rotation angle.

[0034] A resisting plate 29 is fixedly installed on one side of the sliding fixed block 22. The resisting plate 29 is used to contact the driving plate 19. Through the design of the resisting plate 29, when the hydraulic rod 13 drives the first servo motor 14 and the driving plate 19 to move, the driving plate 19 can contact the resisting plate 29, so that the resisting plate 29 can drive the sliding fixed block 22 to move together.

[0035] After the sample plate 4 is fixedly installed on the sliding fixed block 22, the servo motor 17 is started, so that the driving gear 18 can drive the mounting gear plate 16 to rotate. When the mounting gear plate 16 rotates, it can drive the fixing frame 2, the sliding fixed block 22 and the sample plate 4 on the mounting gear plate 16 to rotate together, so that the two sides of the sample plate 4 to be detected can face the irradiation head 11 and the imaging plate 12. After rotating to a suitable angle, the driving plate 19 is just in the middle of the abutting plate 29 on the sliding fixed block 22. Then the hydraulic rod 13 is started, so that the hydraulic rod 13 can drive the driving plate 19 to slide downward. When the driving plate 19 slides downward, it will push the abutting plate 29 to slide downward together, so that the abutting plate 29 can drive the sliding fixed block 22 and the sample plate 4 to slide downward together, so that the sample plate 4 can be between the irradiation head 11 and the imaging plate 12, and then the sample plate 4 is irradiated by the irradiation head 11 to complete the detection.

[0036] It should be noted that, after a sample plate 4 is inspected, the hydraulic rod 13 will pull the drive plate 19 to slide upwards, and then the servo motor 17 will be started again, so that the servo motor 17 drives the mounting gear plate 16 to rotate, so that the next sample plate 4 to be inspected can be moved between the irradiation head 11 and the imaging plate 12, and then the hydraulic rod 13 will be started again to drive the next sample plate 4 to slide downwards for inspection through the drive plate 19.

[0037] In this embodiment: The design of the mounting sprocket 16, multiple fixing brackets 2, and multiple sliding fixing blocks 22 enables multiple sample plates 4 to be placed below the mounting sprocket 16 at one time, allowing the device to detect multiple sample plates 4 in one batch. At the same time, through the design of the servo motor 17 and the driving gear 18, the rotation of the mounting sprocket 16 can be controlled each time, enabling the mounting sprocket 16 to rotate a certain angle each time, achieving precise positioning and cyclic detection of multiple sample plates 4, thus preventing missed detection of the sample plates 4. At the same time, the meshing transmission between the driving gear 18 and the mounting sprocket 16 and the support structure of the fixed tube 14 ensure the rotational stability of the mounting sprocket 16, provide stable support for the sample plate 4, enable the sample plate 4 to be stable during rotation, and at the same time enable the sample plate 4 to be directly facing the irradiation of the irradiation head 11.

[0038] Embodiment 2. This embodiment aims to facilitate the solution to the problem that after the detection of the sample plates 4, confusion may occur between the sample plates 4, making it difficult to distinguish them. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 - 10 , a sliding groove 21 is provided on the fixing bracket 2, and the sliding fixing block 22 is slidably connected to the sliding groove 21. The sliding groove 21 is used to limit the sliding fixing block 22. Through the design of the sliding groove 21, the sliding fixing block 22 can slide within a predetermined trajectory, preventing the subsequent sliding fixing block 22 from shifting in position during the sliding process. A elastic spring 212 is provided between the fixing bracket 2 and the fixing block 22. Through the design of the elastic spring 212, power can be provided for the subsequent reset of the sliding fixing block 22, enabling the sliding fixing block 22 to automatically return to its initial state.

[0039] The upper end of the sliding rod 34 is used to abut against the inclined surface of the triangular abutting block 32. A third spring 36 is sleeved on the sliding rod 34, and the third spring 36 is arranged inside the sliding rod 3. Through the design of the third spring 36, the subsequent sliding rod 34 can return to its initial state under the action of the third spring 36 after sliding. A clamping block 38 is provided at the lower end of the sliding rod 3. Through the design of the clamping block 38, the sample plate 4 can be clamped, enabling the sample plate 4 to be fixed on the sliding fixing block 22.

[0040] A sliding abutting strip 23 is slidably connected inside the sliding fixing block 22. One end of the sliding abutting strip 23 is fixedly connected to an abutting block 28, and a fourth spring 27 is provided at one end of the sliding abutting strip 23. The fourth spring 27 is installed on the sliding fixing block 22. Through the design of the fourth spring 27, the subsequent sliding abutting strip 23 can be driven to return to its original position under the action of the fourth spring 27 after moving.

[0041] Grooves 210 are provided on both sides of the fixing bracket 2, and a convex block 211 is provided on one side of the groove 210.

[0042] When the driving plate 19 drives the receiving plate 29 and the sliding fixing block 22 to slide downward, the elastic spring 212 will be deformed. Through this design, the subsequent elastic spring 212 will pull the sliding fixing block 22 to slide upward, so that the sliding fixing block 22 can be reset.

[0043] Subsequently, when all the sample plates 4 have been detected and need to be removed from the device, when the driving plate 19 drives the receiving plate 29 and the sliding fixing block 22 to slide downward, the sliding rod 3 and the abutting rod 31 inside the sliding rod 3 will slide together. When the abutting rod 31 slides to the groove 210, the abutting rod 31 will slide into the groove 210 under the action of the second spring 33. When the abutting rod 31 slides into the groove 210, it will drive the triangular abutting block 32 to slide together, so that the triangular abutting block 32 slides to the right together, and at the same time, the sliding rod 34 can slide upward under the action of the third spring 36. When the sliding rod 34 slides upward, it will drive the marker pen 35 to slide upward together. Through the upward sliding of the marker pen 35, one side of the sample plate 4 will be marked, so that each sample plate 4 will be marked by the marker pen 35 of different colors, thus facilitating the distinction of the sample plates 4.

[0044] When the abutting rod 31 slides out of the groove 210, the fixing frame 2 will abut against the abutting rod 31, so that the abutting rod 31 can slide into the interior of the sliding fixing block 22. When the abutting rod 31 slides into the sliding fixing block 22, it will drive the triangular abutting block 32 to slide together, and at the same time, the inclined surface of the triangular abutting block 32 will abut against the upper end of the sliding rod 34, so that the sliding rod 34 can slide downward. When the sliding rod 34 slides downward, the third spring 36 will be deformed, thus providing power for the subsequent upward sliding of the sliding rod 34.

[0045] It should be noted that the width of the sliding rod 3 is greater than the width of the groove 210. When the sliding rod 3 slides to the groove 210, the sliding rod 3 will not get stuck in the groove 210.

[0046] It should be noted that through the abutment of the first spring 37 on the sliding rod 3, the lower end of the sliding rod 3 can drive the clamping block 38 to clamp the sample plate 4. At the same time, through the design of the first spring 37, when the abutting rod 31 and the sliding rod 34 slide in the sliding rod 3, under the action of the first spring 37, the sliding rod 3 will not slide, so that the sliding rod 3 can always be in a stable state.

[0047] In this embodiment: through the design of the marking pen 35, after the sample plate 4 is irradiated and tested by the irradiation head 11, a mark can be drawn on one side of the sample plate 4 under the action of the groove 210, the abutment rod 31, the triangular abutment block 32 and the slide bar 34, so that a mark can be drawn on the sample plate 4, so that the sample plate 4 can be automatically marked during the detection process, and there is no need to waste labor for marking the sample plate 4, further reducing the subsequent labor cost; Moreover, through the design of the clamping block 38 at one end of the sliding rod 3 , the clamping block 38 can clamp the sample plate 4 , so that the sample plate 4 can be stably fixed on the sliding fixing block 22 .

[0048] Embodiment 3: This embodiment is intended to promote the solution of the problem that the sample plates 4 need to be removed one by one after the test, which increases the operation time. This embodiment is an improvement made on the basis of Embodiment 1 and Embodiment 2. For details, please refer to Figures 1 - 10 , one end of the sliding rod 3 is in contact with a first spring 37, and the first spring 37 is fixedly installed inside the sliding fixed block 22. Through the design of the first spring 37, the sliding rod 3 can be driven to return to its original position under the action of the first spring 37 after the subsequent movement. The sliding rod 3 is slidably connected with a resisting rod 31 inside, and a triangular resisting block 32 is provided at one end of the resisting rod 31. A second spring 33 is sleeved on the resisting rod 31. Through the design of the second spring 33, after the subsequent movement of the resisting rod 31, the resisting rod 31 can be driven to return to its original position under the action of the second spring 33. Through the design of the groove 210, when the resisting rod 31 moves to the groove 210, a space for the resisting rod 31 to move is provided; One end of the sliding rod 3 is used to abut against the protrusion 211 . Through the design of the protrusion 211 , when one end of the sliding rod 3 abuts against the protrusion 211 , the sliding rod 3 can slide.

[0049] The other end of the sliding resistance bar 23 is provided with a resistance inclined surface 24, which is used to resist the resistance block 28. The sliding resistance bar 23 is slidably connected with a resistance inclined block 25. A fifth spring 26 is provided on one side of the resistance inclined block 25. The fifth spring 26 is installed inside the sliding resistance bar 23. Through the design of the fifth spring 26, after the subsequent resistance inclined block 25 moves, the resistance inclined block 25 can be driven to return to its original position under the action of the fifth spring 26.

[0050] When all the sample plates 4 on the mounting toothed disc 16 have been tested, the servo motor 17 is started to drive the driving gear 18 to reverse, so that the mounting toothed disc 16 can reverse. Figure 5, one side of the driving plate 19 can be in contact with one side of the contact inclined block 25. Subsequently, the mounting sprocket 16 continues to rotate. During the rotation of the mounting sprocket 16, the contact inclined block 25 is under the contact of the driving plate 19, so that the contact inclined block 25 can drive the sliding contact bar 23 to slide in the sliding fixing block 22, and the sliding contact bar 23 can drive the contact block 28 to slide together; During the sliding of the contact block 28, it can contact the contact inclined surface 24 at one end of the sliding contact bar 23. During the contact of the contact block 28 with the contact inclined surface 24, the sliding contact bar 23 can be made to slide, so that the sliding contact bar 23 can drive the contact block 28 at the other end to contact the adjacent contact inclined surface 24. At the same time, when the contact block 28 moves to the maximum position, one end of the contact block 28 is already above the receiving plate 29. Under the action of the contact block 28 and the receiving plate 29, the multiple fixing frames 2 are connected together and can move uniformly. Subsequently, the hydraulic rod 13 is started to drive the driving plate 19 to slide downward, so that each sliding fixing block 22 can slide downward with the driving plate 19, realizing the simultaneous downward sliding of each sample plate 4.

[0051] As the driving plate 19 drives the receiving plate 29 to continue sliding downward, when the sliding fixing block 22 and the sliding rod 3 are driven to the convex block 211, under the contact of the convex block 211 with the sliding rod 3, the sliding rod 3 will slide into the interior of the sliding fixing block 22, and the sliding rod 3 will contact the first spring 37, causing the first spring 37 to deform, providing power for the subsequent reset of the sliding rod 3. While sliding, the sliding rod 3 will drive the clamping block 38 to slide together, so that the clamping block 38 releases the clamping of the sample plate 4, enabling the sample plate 4 to slide out of the sliding fixing block 22. After the sample plate 4 slides out of the sliding fixing block 22, the hydraulic rod 13 is controlled to slide upward, so that the receiving plate 29 is no longer in contact with the driving plate 19, and the sliding fixing block 22 can slide upward under the action of the elastic spring 212, enabling each sliding fixing block 22 to return to the initial position; As the hydraulic rod 13 drives the driving plate 19 to continue sliding upward, the driving plate 19 will no longer contact the straight surface of the contact inclined block 25, so that the sliding contact bar 23 can slide back under the action of the fourth spring 27, and the contact block 28 will no longer contact the adjacent contact inclined surface 24, enabling each sliding contact bar 23 to drive each contact block 28 to return to the initial position; At the same time, when placing the sample plate 4 to be tested on the sliding fixed block 22, it is only necessary to pull the clamping block 38 so that the clamping block 38 drives the sliding rod 3 to slide together, so that the sample plate 4 can be placed in the sliding fixed block 22, and then release the clamping block 38, so that the clamping block 38 will clamp the sample plate 4 under the action of the first spring 37.

[0052] It should be noted that when the mounting gear disc 16 rotates normally, the driving plate 19 will interfere with the inclined surface of the interference bevel 25, causing the interference bevel 25 to slide into the interior of the sliding interference strip 23, and at the same time, the interference bevel 25 will squeeze the fifth spring 26, causing the fifth spring 26 to deform. After the driving plate 19 slides over the interference bevel 25, the interference bevel 25 will be restored to its initial state under the action of the fifth spring 26. Through such a design, the interference bevel 25 will not be affected by the driving plate 19 during the rotation of the mounting gear disc 16, so that the equipment can operate normally.

[0053] In this embodiment: through the cooperation between the sliding resistance strips 23, the resistance inclined surfaces 24, the resistance inclined blocks 25, and the resistance blocks 28 on each sliding fixed block 22, the resistance block 28 on one sliding fixed block 22 can resist the resistance inclined surfaces 24 on the adjacent sliding fixed block 22, so that the resistance inclined surfaces 24 on the adjacent sliding fixed block 22 can be resisted by the resistance block 28, so that the sliding resistance strip 23 can drive the resistance block 28 to resist the resistance inclined surfaces 24 on the next sliding fixed block 22, so that the sliding fixed blocks 22 can cooperate with each other through the resistance blocks 28, so that the resistance blocks 28 can move to the upper side of the resistance plates 29 on the adjacent sliding fixed blocks 22, so that each sliding fixed block 22 can slide downward at the same time, further reducing the subsequent labor costs.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
