Description

Technical Field

[0001] This application relates to the field of apparatus for applying fluids to surfaces, and more particularly to a coupling agent coating apparatus. Background Technology

[0002] Magnetostrictive ultrasonic guided wave testing technology is widely used in non-destructive testing of metallic materials. For example, iron-cobalt strips generate torsional waves through magnetostriction in an alternating magnetic field. During testing, the iron-cobalt strips are usually attached to the pipe with a coupling agent to achieve an ideal measurement environment. The torsional waves are then transmitted from the iron-cobalt strips to the pipe through the coupling agent for non-destructive testing of the pipe. The application of the coupling agent is a key step in the testing process.

[0003] Because the iron-cobalt strip is designed as a long, thin sheet, it is highly flexible and easy to curl. To facilitate the application of coupling agent, the common methods for applying coupling agent in the industry are mainly divided into manual application and simple tool application. Manual application usually requires two people to work together, with each person holding one end of the iron-cobalt strip and the other person applying the coupling agent with a metal rod or brush. This method has the disadvantages of low efficiency and uneven application. Simple tool application uses a brush-like tool, which also requires two people to operate. Although simple tool application improves the efficiency of two-person operation, the application quality of coupling agent on the iron-cobalt strip, such as uniformity and thickness consistency, is still difficult to guarantee, and there is also a serious waste of coupling agent. Summary of the Invention

[0004] In order to reduce the amount of manual labor required for coating while ensuring uniformity and thickness consistency of the coupling agent coating on the iron-cobalt strip, this application provides a coupling agent coating device.

[0005] The coupling agent coating device provided in this application adopts the following technical solution: A coupling agent application device, comprising: A storage bin, wherein the storage bin is hollow and forms a storage cavity; The discharge frame is connected to the storage bin. The inner wall of the discharge frame has multiple discharge holes, and the inner hole of the discharge frame forms a coating window. The inner cavity of the storage bin is connected to the coating window through the discharge holes. A pressure valve extends into the inner cavity of the storage bin and can slide relative to the inner wall of the storage bin. When the pressure valve moves toward the discharge frame, it pushes the material in the storage bin into the discharge hole. A drive unit for moving the pressure valve, the drive unit being connected to the discharge frame and the pressure valve.

[0006] By adopting the above technical solution, the pressure valve is removed from the storage hopper, then the coupling agent is added to the storage hopper, and the pressure valve is inserted back into the storage hopper. The iron-cobalt strip is then passed through the coating window. The operator holds the storage hopper with one hand and pulls the iron-cobalt strip with the other, applying force to the pressure valve via the drive unit, causing the pressure valve to move towards the discharge port. Simultaneously, the pressure valve moves, squeezing the coupling agent inside the storage hopper, causing it to be discharged from the discharge port to the coating window and finally coated onto the iron-cobalt strip. This process is repeated, moving the iron-cobalt strip while simultaneously applying force to the pressure valve until the coupling agent is fully coated onto the iron-cobalt strip. During this process, the quality of the coupling agent discharged from each discharge port is relatively consistent, which improves the adhesion of the coupling agent on the iron-cobalt strip compared to manual coating. The design ensures uniform coating and allows for easy installation of the iron-cobalt strip onto the corresponding position on the pipeline. The couplant coating device utilizes a storage hopper to store the couplant and a discharge frame to create a discharge hole and coating window, providing a suitable location for coating the iron-cobalt strip with the couplant. A pressure valve allows the couplant in the storage hopper to be extruded through the discharge hole, and a drive unit can move the pressure valve. This design ensures uniform coating and consistent thickness of the couplant on the iron-cobalt strip while reducing the amount of manual labor required for coating.

[0007] In one specific implementation, a plurality of brushes are connected to the discharge frame, the brushes are positioned close to the discharge hole, and the brushes are connected to the side of the discharge frame where the discharge hole is located.

[0008] By adopting the above technical solution, the designed brush can work in conjunction with the reciprocating iron-cobalt belt to achieve uniform application of the coupling agent.

[0009] In one specific implementation, the drive unit includes: A grip handle is connected to the discharge frame, and a guide groove is formed on the grip handle; A control belt is connected to the end of the pressure valve away from the discharge frame, and both ends of the control belt pass through the grip handle and extend into the guide groove. A connecting slider slides within the guide groove relative to the grip handle, and the connecting slider can be connected to the end of the control band.

[0010] By adopting the above technical solution, the pressure valve is removed from the storage hopper, then the coupling agent is added to the storage hopper, the pressure valve is then inserted into the storage hopper, and then the iron-cobalt strip is passed through the coating window. The operator holds the handle with one hand, pressing the connecting slider with their thumb, while pulling the iron-cobalt strip with the other hand. This pull causes the control belt to move downwards via the connecting slider, applying force to the pressure valve and causing it to move towards the discharge port. As the pressure valve moves, it squeezes the coupling agent in the storage chamber, causing it to be discharged from the discharge port to the coating window, ultimately being applied to the iron-cobalt strip. This process is repeated, moving the iron-cobalt strip while simultaneously applying force to the pressure valve until the coupling agent is fully applied. During this process, the quality of the coupling agent discharged from each discharge port is relatively uniform, improving the overall coating uniformity on the iron-cobalt strip compared to manual application. The iron-cobalt strip can then be removed and installed in the corresponding position on the pipeline. The designed drive unit allows for easy one-handed operation via the handle, and the control belt, in conjunction with the connecting slider, applies force to the pressure valve. The connecting slider is positioned so that the operator can hold it with one hand while simultaneously pressing it with their thumb, thus completing the coupling agent extrusion operation.

[0011] In one specific implementation, the handle and the brush are located on the same side or opposite sides of the iron-cobalt strip. When the handle and the brush are on the same side of the iron-cobalt strip, the handle is above the brush. When the handle and the brush are on opposite sides of the iron-cobalt strip, the handle is below the brush.

[0012] By adopting the above technical solution, the designed grip and brush located on the same side or opposite sides of the iron-cobalt strip can ensure normal coating of the iron-cobalt strip while changing the vertical positional relationship between the grip and the storage bin.

[0013] In one specific implementation, a placement strip is slidably connected to the discharge frame, the moving plane of the placement strip is arranged perpendicular to the central axis of the discharge hole, and a magnetic suction layer for placing iron-cobalt strip is formed on the side of the placement strip facing the discharge hole.

[0014] By adopting the above technical solution, the designed placement strip can serve as the supporting foundation for the iron-cobalt strip, replacing manual reciprocating pulling, and can further improve the uniformity of the coupling agent coating on the iron-cobalt strip.

[0015] In one specific implementation, the drive unit includes: A drive gear is rotatably connected to the discharge frame, and the drive gear meshes with the side of the placement bar away from the discharge hole; A transmission reversing module with its input shaft and output shaft arranged vertically, wherein the input shaft of the transmission reversing module is coaxially connected to the drive gear; The linkage gear is coaxially connected to the output shaft of the transmission reversing module, and the storage bin is rotatably connected to the discharge frame. The rotation axis of the storage bin is perpendicular to the plane where the placement bar is located, and the linkage gear meshes with the annular tooth groove formed on the outer ring of the storage bin. A drive module for controlling the movement of the pressure valve, the drive module being connected to the pressure valve and the storage bin.

[0016] By adopting the above technical solution, the iron-cobalt strip is placed on the placement bar and fixed by magnetic attraction. Then, force is applied to the drive gear to make it rotate. The rotation of the drive gear drives the placement bar to move. At the same time, the rotation of the drive gear, through the transmission reversing module, applies force to the linkage gear to make it rotate. The rotation of the linkage gear drives the storage bin to rotate, so that the coupling agent in the storage bin can change position relative to the storage bin. This facilitates the temperature uniformity of the coupling agent distributed radially along the storage bin and ensures the uniformity of the discharge speed of the multiple discharge holes distributed radially along the storage bin. At the same time, the drive module controls the movement of the pressure valve to complete the extrusion of the coupling agent. The designed drive unit can realize the reciprocating movement of the placement bar through the drive gear. The transmission reversing module facilitates the transmission of the rotation of the drive gear to the linkage gear, and makes the movement speed of the placement bar and the rotation speed of the storage bin correlated. The linkage gear can drive the rotation of the storage bin, which facilitates the temperature uniformity of the coupling agent distributed radially along the storage bin and ensures the uniformity of the discharge speed of the multiple discharge holes distributed radially along the storage bin. The drive module can control the movement of the pressure valve.

[0017] In one specific implementation, the driving module includes: A connecting frame is connected to the pressure valve. The connecting frame is connected to the storage bin via a telescopic component, and the connecting frame can move relative to the storage bin along the central axis of the storage bin via the telescopic component.

[0018] By adopting the above technical solution, the designed drive module can realize the relative movement of the pressure valve and the storage bin through the cooperation of the connecting frame and the telescopic component, thereby squeezing out the coupling agent in the storage bin.

[0019] In one specific implementation, a spiral stirring spring with a built-in heating module is connected to the discharge frame. The spiral stirring spring is located in the inner cavity of the storage bin, and the spiral radius of the spiral stirring spring gradually decreases along the central axis of the storage bin toward the pressure valve.

[0020] By adopting the above technical solution, the spiral stirring spring can heat the coupling agent to improve its fluidity through the built-in heating module, while the rotating storage bin can improve the temperature uniformity of the coupling agent throughout the storage bin.

[0021] In one specific implementation, the pressure valve is equipped with a rubber sealing ring, and the rubber sealing ring can abut against and slide relative to the inner wall of the storage bin.

[0022] By adopting the above technical solution, the designed rubber sealing ring can improve the sliding sealing performance between the pressure valve and the storage bin.

[0023] In one specific implementation, the storage bin is made of a transparent material.

[0024] By adopting the above technical solution, the storage bin designed with transparent material can facilitate staff to observe the remaining amount of coupling agent and the extrusion status inside the storage bin.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The designed coupling agent coating device uses a storage bin as a structure for storing coupling agent and a discharge frame to form a discharge hole and coating window, thus providing a place for coating coupling agent on the iron-cobalt strip. The coupling agent in the storage bin can be squeezed out through the discharge hole by a pressure valve, and the pressure valve can be moved by a drive unit. This device ensures uniformity and thickness consistency of coupling agent coating on the iron-cobalt strip while reducing the amount of manual labor required for coating.

[0026] The designed coupling agent application device is easy for workers to hold with one hand via a handle, and the control belt can work with the connecting slider to apply force to the pressure valve. The position of the connecting slider is convenient for workers to hold with one hand while pressing with their thumb, thereby completing the coupling agent extrusion operation.

[0027] The designed coupling agent coating device enables the reciprocating movement of the placement strip via a drive gear. The transmission reversing module facilitates the transmission of the drive gear's rotation to the linkage gear, establishing a correlation between the movement speed of the placement strip and the rotation speed of the storage bin. The linkage gear drives the storage bin to rotate, thereby ensuring temperature uniformity of the coupling agent distributed radially along the storage bin and guaranteeing consistent discharge speeds from the multiple discharge holes radially distributed along the storage bin. The drive module controls the movement of the pressure valve. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0035] This application discloses a coupling agent application device.

[0036] Example 1: Reference Figure 1 and Figure 2 A coupling agent coating device includes a storage bin 1, a discharge frame 2, and a pressure valve 3. The storage bin 1 is hollow and has a storage cavity for containing coupling agent. The discharge frame 2 is connected to the storage bin 1. Multiple discharge holes 21 are provided on the inner wall of the discharge frame 2, and the inner hole of the discharge frame 2 forms a coating window 22. The inner cavity of the storage bin 1 is connected to the coating window 22 through the discharge holes 21. The pressure valve 3 extends into the inner cavity of the storage bin 1 and can slide relative to the inner wall of the storage bin 1. When the pressure valve 3 moves toward the discharge frame 2, it pushes the coupling agent in the storage bin 1 into the coating window 22 through the discharge holes 21.

[0037] Reference Figure 2 In order to improve the sliding sealing performance between the pressure valve 3 and the inner wall of the discharge hopper, a rubber sealing ring 8 is embedded in the pressure valve 3. The rubber sealing ring 8 can abut against and slide relative to the inner wall of the storage hopper 1. Furthermore, in order to facilitate the staff to observe the remaining amount of coupling agent and the extrusion status in the storage hopper 1, the storage hopper 1 is made of transparent materials such as glass and transparent plastic.

[0038] Reference Figure 2 Furthermore, in order to improve the uniformity and consistency of the coupling agent extruded through the discharge hole 21 and applied to the iron-cobalt strip, a plurality of brushes 5 are inserted into the discharge frame 2. The brushes 5 are positioned close to the discharge hole 21 and are connected to the side of the discharge frame 2 where the discharge hole 21 is located.

[0039] Reference Figure 2 Specifically, in order to drive the pressure valve 3 to move and extrude the coupling agent in the storage bin 1, the coupling agent coating device also includes a drive unit 4. The drive unit 4 is connected to the discharge frame 2 and the pressure valve 3. Specifically, the drive unit 4 includes a handle 41, a control belt 42 and a connecting slider 43. The handle 41 is welded and fixed to the discharge frame 2, and a guide groove 411 is formed on the handle 41. The control belt 42 is fixedly connected to the side of the pressure valve 3 away from the discharge frame 2, and both ends of the control belt 42 pass through the handle 41 and extend into the guide groove 411. The control belt 42 is slidably connected to the handle 41. The connecting slider 43 slides relative to the handle 41 in the guide groove 411, and the connecting slider 43 can be connected to both ends of the control belt 42 at the same time.

[0040] Reference Figure 2 Remove the pressure valve 3 from the storage hopper 1, then add the coupling agent to the storage hopper 1, and insert the pressure valve 3 back into the storage hopper 1. Then, pass the iron-cobalt strip through the coating window 22. The operator holds the handle 41 with one hand and presses the connecting slider 43 with their thumb, while pulling the iron-cobalt strip with the other hand. This causes the control belt 42 to move downwards via the connecting slider 43. As the control belt 42 moves downwards, it applies force to the pressure valve 3, causing it to move towards the discharge port 21. Simultaneously, the pressure valve 3 squeezes the coupling agent in the storage hopper 1, causing it to be discharged from the discharge port 21 to the coating window 22, ultimately coating the iron-cobalt strip. Repeatedly move the iron-cobalt strip while simultaneously applying force to the pressure valve 3 until the coupling agent on the iron-cobalt strip is fully coated. During this process, the quality of the coupling agent discharged from each discharge hole 21 is relatively similar. Compared with manual brushing, it can improve the uniformity of the coating on the iron-cobalt strip. Furthermore, the iron-cobalt strip can be removed and installed on the corresponding position on the pipeline. In this application, the connecting slider 43 can be separately set from the grip handle 41, and the connecting slider 43 can also be slidably connected to the grip handle 41. The connecting slider 43 is connected to the control strip 42 by screws. The connecting slider 43 can also include two blocks with a snap-fit ​​connection structure, and the control strip 42 is fixed by snap-fit.

[0041] Reference Figure 2 and Figure 3The handle 41 and the brush 5 are located on the same side or opposite sides of the iron-cobalt strip. When the handle 41 and the brush 5 are on the same side of the iron-cobalt strip, the handle 41 is above the brush 5. When the handle 41 and the brush 5 are on opposite sides of the iron-cobalt strip, the handle 41 is below the brush 5. When the handle 41 is below the brush 5, the opening of the storage bin 1 faces upward, which reduces the possibility of the coupling agent leaking out through the sliding gap between the storage bin 1 and the pressure valve 3. When the handle 41 is above the brush 5, the main mass is lowered, which makes it easier for workers to grasp and maintain structural stability.

[0042] The implementation principle of the coupling agent coating device in Embodiment 1 of this application is as follows: The pressure valve 3 is removed from the storage hopper 1, then the coupling agent is added to the storage hopper 1. The pressure valve 3 is then inserted back into the storage hopper 1. The iron-cobalt strip is then passed through the coating window 22. The operator holds the handle 41 with one hand and presses the connecting slider 43 with their thumb, while pulling the iron-cobalt strip with the other hand. This causes the control belt 42 to move downwards via the connecting slider 43. Simultaneously, the control belt 42 exerts force on the pressure valve 3, causing it to face the discharge hole 2. As the pressure valve 3 moves, it squeezes the coupling agent in the inner cavity of the storage bin 1, causing the coupling agent to be discharged from the discharge hole 21 to the coating window 22, and finally coated onto the iron-cobalt strip. The iron-cobalt strip is moved repeatedly while applying force to the pressure valve 3 until the coupling agent on the iron-cobalt strip is properly coated. During this process, the mass of the coupling agent discharged from each discharge hole 21 is relatively similar. Compared with manual brushing, it can improve the uniformity of the coating on the iron-cobalt strip. Then, the iron-cobalt strip can be removed and installed on the corresponding position on the pipeline.

[0043] The storage bin 1 serves as a structure for storing coupling agent, and the discharge frame 2 forms a discharge hole 21 and a coating window 22, thus providing a place for coating coupling agent on the iron-cobalt strip. The pressure valve 3 can squeeze the coupling agent in the storage bin 1 through the discharge hole 21, and the drive unit 4 can drive the pressure valve 3 to move. This ensures the uniformity and thickness consistency of the coupling agent coating on the iron-cobalt strip while reducing the amount of manual labor required for coating.

[0044] Example 2: Reference Figure 4 The difference between this embodiment and Embodiment 1 is that: a placement strip 6 is slidably connected to the discharge frame 2, the moving plane of the placement strip 6 is set perpendicular to the hollow axis of the discharge hole 21, and a magnetic layer is formed on the side of the placement strip 6 facing the discharge hole 21. The magnetic layer is used to place and magnetically fix the iron-cobalt strip. It should be noted that the magnetic force generated by the magnetic layer is only used to apply a limited force to the iron-cobalt strip to keep the position of the iron-cobalt strip stable during the application of the coupling agent.

[0045] Reference Figure 4 and Figure 5In order to drive the pressure valve 3 to move and drive the placement bar 6 to reciprocate, the drive unit 4 includes a drive gear 44, a transmission reversing module 45, a linkage gear 46, and a drive module 47. The drive gear 44 is rotatably connected to the discharge frame 2, and the drive gear 44 meshes with the side of the placement bar 6 away from the discharge hole 21. The transmission reversing module 45 has an input shaft and an output shaft, and the input shaft and the output shaft are axially perpendicular. The transmission reversing module 45 can be a bevel gear set or other structures that can achieve the same function. The input shaft of the transmission reversing module 45 is coaxially connected to the drive gear 44. It should be noted that a micro motor is connected to one side of the storage frame, which drives the drive gear 44 to rotate.

[0046] Reference Figure 4 and Figure 5 The linkage gear 46 is coaxially connected to the output shaft of the transmission reversing module 45, and the storage bin 1 is rotatably connected to the discharge frame 2. The rotation axis of the storage bin 1 is parallel to the axial direction of the output shaft of the transmission reversing module 45, that is, the rotation axis of the storage bin 1 is perpendicular to the plane where the placement bar 6 is located. The outer periphery of the storage bin 1 is fitted with an annular toothed groove, and the linkage gear 46 meshes with the annular toothed groove. It should be emphasized that there is a transmission ratio between the two bevel gears of the transmission reversing module 45, such as the linkage gear 46 rotating five times when the drive gear 44 rotates one revolution, or it can be other appropriate transmission ratios.

[0047] Reference Figure 4 and Figure 5 The drive module 47 is connected to the pressure valve 3 and the storage bin 1. Specifically, the drive module 47 includes a connecting frame 471 and a telescopic component 472. The connecting frame 471 is welded and fixed to the pressure valve 3. There are multiple telescopic components 472. The body of the telescopic component 472 is connected to the storage bin 1, and the movable end of the telescopic component 472 is connected to the connecting frame 471, so that the connecting frame 471 can move relative to the storage bin 1 along the rotation axis of the storage bin 1. In this application, the telescopic component 472 can be a miniature cylinder, a miniature electric telescopic rod, or other structures with linear telescopic function.

[0048] Reference Figure 5 Furthermore, a spiral stirring spring 7 is welded and fixed on the discharge frame 2. The spiral stirring spring 7 is hollow, and a heating module such as a heating wire is inserted into the inner cavity of the spiral stirring spring 7. The spiral stirring spring 7 is located in the inner cavity of the storage bin 1, and the spiral radius of the spiral stirring spring 7 gradually decreases along the rotation axis of the storage bin 1 toward the pressure valve 3. The side of the spiral stirring spring 7 away from the discharge frame 2 abuts against the pressure valve 3 and can generate elastic deformation as the pressure valve 3 moves.

[0049] The implementation principle of the coupling agent coating device in Embodiment 2 of this application is as follows: The pressure valve 3 is removed from the storage hopper 1, then the coupling agent is added to the storage hopper 1. The pressure valve 3 is then inserted back into the storage hopper 1. The iron-cobalt strip is placed on the placement strip 6 and fixed magnetically. Force is applied to the drive gear 44 to make it rotate. The rotation of the drive gear 44 moves the placement strip 6. Simultaneously, as the drive gear 44 rotates, force is applied to the linkage gear 46 through the transmission reversing module 45, causing the linkage gear 46 to rotate. As the wheel 46 rotates, it drives the storage bin 1 to rotate, allowing the coupling agent in the storage bin 1 to change position relative to the storage bin 1. This facilitates the uniformity of temperature of the coupling agent distributed radially along the storage bin 1, ensuring the uniformity of the discharge speed of the multiple discharge holes 21 distributed radially along the storage bin 1. At the same time, the pressure valve 3 is moved by the drive module 47 to complete the extrusion of the coupling agent. The extruded coupling agent is evenly coated onto the iron-cobalt strip on the placement strip 6 under the force of the brush 5 until the coupling agent on the iron-cobalt strip is fully coated.

[0050] The reciprocating movement of the placement bar 6 can be realized by the drive gear 44. The rotation of the drive gear 44 can be transmitted to the linkage gear 46 by the transmission reversing module 45, and a correlation is established between the moving speed of the placement bar 6 and the rotation speed of the storage bin 1. The linkage gear 46 can drive the storage bin 1 to rotate, which facilitates the temperature uniformity of the coupling agent distributed radially along the storage bin 1 and ensures the uniformity of the discharge speed of the multiple discharge holes 21 distributed radially along the storage bin 1. The movement of the pressure valve 3 can be controlled by the drive module 47.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
