[0033] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0034] like Figures 1 to 4 As shown, an upper mold flow regulating mechanism of a compact coating die head includes a baffle 1, an adjusting rod 2, a driving device 3, a connecting rod 4 and an adjusting seat 5. The driving device 3 is connected to one end of the connecting rod 4, and the other end of the connecting rod 4 is installed on the adjusting seat 5. The connecting rod 4 is arranged in a horizontal direction, and the lower part of the adjusting seat 5 is connected to one end of the adjusting rod 2. The baffle 1 is installed at the bottom of the adjusting rod 2, and the adjusting rod 2 is arranged in a vertical direction. The driving device 3 can drive the connecting rod 4 to rotate, and the connecting rod 4 can drive the adjusting seat 5 to move up and down. An eccentric wheel 6 is eccentrically provided at the end of the connecting rod 4 close to the adjusting seat 5, and an elliptical groove 51 is provided on the adjusting seat 5 corresponding to the eccentric wheel 6. When the eccentric wheel 6 rotates, the rim of the eccentric wheel 6 contacts the inner wall of the elliptical groove 51 to drive the adjusting seat 5 to move up and down, and the adjusting seat 5 can drive the adjusting rod 2 and the baffle 1 to move up and down.

[0035] When the present application adjusts the paint flow rate, first, the driving device 3 drives the connecting rod 4 to rotate, and the connecting rod 4 drives the rim of the eccentric wheel 6 to rotate on the inner wall of the elliptical groove 51 of the adjusting seat 5, thereby driving the adjusting seat 5 to perform lifting and lowering movements, and the adjusting seat 5 drives the adjusting rod 2 and the flow block 1 to perform lifting and lowering movements. In addition, the connecting rod 4 of the present application is arranged in a horizontal direction, and the adjusting rod 2 is arranged in a vertical direction. By setting the connecting rod 4 in a horizontal direction, the adjusting device can occupy less space in the horizontal direction. This is particularly useful in application scenarios with limited space, and can make the paint flow regulating device more compact and suitable for environments with limited space.

[0036] In addition, the horizontal arrangement of the connecting rod 4 can make the rim of the eccentric wheel 6 rotate smoothly in the elliptical groove 51. Since the horizontal movement is relatively stable, the vibration and swing in the system movement can be reduced, thereby improving the stability and accuracy of the entire paint flow regulation process.

[0037] The connecting rod 4 and the adjusting rod 2 are respectively in the horizontal and vertical directions, so that when operating the adjusting device, the operator can more easily grasp the direction and movement path, which reduces the difficulty of operation and improves the accuracy of adjustment.

[0038] like Figure 5As shown, in this embodiment, a first mounting plane 41 is provided on the side of the connecting rod 4, and a second mounting plane 61 is provided on the eccentric wheel 6 corresponding to the first mounting plane 41, and the eccentric wheel 6 is mounted in cooperation with the first mounting plane 41 of the connecting rod 4 through the second mounting plane 61. The eccentric wheel 6 is mounted in a plane manner, which can provide sufficient contact area to ensure stable installation of the eccentric wheel 6; it can ensure a firm connection and reduce the possibility of loosening or shaking of the eccentric wheel 6 during movement.

[0039] In this embodiment, a threaded through hole 62 is provided on the side surface of the eccentric wheel 6 along the radial direction, and the eccentric wheel 6 is locked on the connecting rod 4 by screws matching the threaded through hole 62 .

[0040] In this embodiment, a through groove 52 is provided on the top of the adjustment seat 5, and the through groove 52 is communicated with the oval groove 51. By providing the through groove 52 on the top of the adjustment seat 5 and communicating with the oval groove 51, lubricating oil or grease can be conveniently provided to the eccentric wheel 6 and the oval groove 51. When the eccentric wheel 6 rotates and contacts the inner wall of the oval groove 51, lubrication can reduce friction and provide smooth movement, thereby reducing energy loss and wear.

[0041] The through groove 52 is also provided on the top of the adjusting seat 5 for cooling and heat dissipation. When the eccentric wheel 6 rotates, the through groove 52 can introduce cooling liquid or cooling air into the elliptical groove 51, thereby realizing cooling and heat dissipation of the eccentric wheel 6, and preventing the parts from being damaged due to overheating.

[0042] like Figure 4 and Figure 5 In this embodiment, a first mounting groove 53 is provided at the bottom of the adjusting seat 5, and third mounting planes 21 are respectively provided on the two side surfaces of the upper end of the adjusting rod 2. The adjusting rod 2 is installed in the first mounting groove 53 through the third mounting plane 21. A locking screw 54 is provided on the side of the adjusting seat 5. The locking screw 54 is used to lock the adjusting rod 2 on the adjusting seat 5. When locking, the end face of the locking screw 54 rests on the third mounting plane 21.

[0043] By locking with screws, the adjusting rod 2 can be flexibly adjusted and fixed. According to different coating requirements, the upper end position and tightening degree of the adjusting rod 2 can be adjusted to meet the requirements of different coating thicknesses, thereby improving the flexibility and adaptability of coating. By locking with screws, the adjusting rod 2 can be easily disassembled and replaced. When the adjusting rod 2 needs to be replaced or maintained, the adjusting rod 2 can be quickly removed by simply loosening the screws, performing relevant operations, and then re-fixing the adjusting rod 2, thereby improving the maintainability and replaceability of the adjusting rod 2.

[0044] like Figure 5As shown, in this embodiment, a guide seat 22 is provided on the upper part of the adjusting rod 2, and the guide seat 22 is used to guide the adjusting rod 2. The guide seat 22 can ensure that the adjusting rod 2 maintains stable guidance when the upper part moves, and prevents the adjusting rod 2 from shaking or deviating from the track during the movement, thereby ensuring that the coating thickness adjustment of the coating die head is more stable and reliable. The guide seat 22 can prevent the adjusting rod 2 from lateral deflection or tilting during the movement, and ensure that the adjustment movement of the coating die head remains consistent in the vertical direction, avoiding inaccurate adjustment or uneven coating thickness.

[0045] In this embodiment, the driving device 3 is a cylinder, a motor or a micrometer.

[0046] In this embodiment, the lower adjusting rod 2 driving device 3 is a micrometer, and the threaded end of the micrometer is connected to the threaded hole of the adjusting rod 2. When one end of the micrometer is rotated, the threaded end of the micrometer cooperates with the threaded hole, thereby driving the adjusting rod 2 to move horizontally. The micrometer is a high-precision measuring tool, which can usually measure to an accuracy of 0.001 mm, so it can provide very accurate adjustment and measurement results. The reading display of the micrometer is clear, and the operation is simple, and it is not easy to produce reading errors, which makes it excellent in repetitive adjustment tasks.

[0047] In this embodiment, the driving device 3 of the lower adjustment rod 2 is a motor, and the motor also converts the rotational motion of the electric device into linear motion through a transmission device, so that the lower adjustment rod 2 can move in the lateral direction. Common transmission devices include ball screws, guide rails, gear transmissions, etc. In this embodiment, the lateral movement process can be automatically performed by the motor drive without manual intervention. This improves work efficiency, especially in scenarios where frequent lateral movement is required, which can save a lot of time and labor costs.

[0048] In this embodiment, the lower adjusting rod 2 driving device 3 is a cylinder. The cylinder is a relatively simple mechanical device with a simple and reliable structure and does not require a complex electronic control system. This makes the cylinder drive system have high reliability and stability.

[0049] like Figure 6 As shown, in this embodiment, the spoiler block 1 is installed in the second installation groove 23 at the bottom of the adjusting rod 2, and an overlapping portion 11 is provided at the end of the spoiler block 1. The two spoiler blocks 1 are overlapped with each other through the overlapping portion 11.

[0050] Compared with the one-piece design, the baffle block 1 is installed in the second installation groove 23 at the bottom of the adjusting rod 2, which is more convenient to process. The adjusting rod 2 and the baffle block 1 can be processed as two independent parts, without processing them as a whole. Such a design makes the processing process more simplified and flexible, and can better adapt to different processing requirements and production processes.

[0051] The presence of the overlap 11 can enhance the sealing between the two baffles 1. When the baffles 1 overlap each other through the overlap 11, the possibility of the coating slurry overflowing from the gap between the baffles 11 can be reduced, and the coating slurry leakage can be prevented, thereby improving the control accuracy and consistency of the coating process. After the two baffles 1 overlap each other through the overlap 11, a continuous surface is formed, avoiding gaps or gaps that may appear during the coating process. This implementation can effectively prevent the coating slurry from flowing out of the gap and ensure the uniformity and flatness of the coating layer. The overlap 11 provides a stronger connection between the two baffles 1. Through the setting of the overlap 11, the two baffles 1 can be locked with each other to avoid the movement or falling off of the baffles 1 due to extrusion and pressure during the coating process, thereby increasing the stability and durability of the coating die. The presence of the overlap 11 can make the connection between the two baffles 1 tighter and reduce the unevenness of the coating layer thickness. This implementation helps to ensure the uniformity and consistency of the coating layer and improve the quality of the coated product.

[0052] In this embodiment, the width H of the baffle block 1 is smaller than the diameter D of the adjusting rod 2. Since the baffle block 1 is directly mounted on the adjusting rod 2, the locking screw 54 is used to lock the adjusting rod 2 in the mounting groove 53 at the bottom of the adjusting seat 5, and the locking screw 54 is used to lock the adjusting rod 2 on the adjusting seat 5, and the locking screw 54 is used to lock the adjusting rod 2 on the adjusting seat 5, and the locking screw 54 is used to lock the adjusting rod 2 on the adjusting seat 5 through the overlapping portion 11, and the locking screw 54 is used to lock the adjusting rod 2 on the adjusting seat 5 and overlaps with other baffle block 1 locking screws 54 for locking the adjusting rod 2 on the adjusting seat 5, the upper die head only needs to set the adjusting rod 2 locking screw 54 for locking the adjusting rod 2 on the adjusting seat 5, and there is no need to additionally set an independent baffle block 1 locking screw 54 for locking the adjusting rod 2 on the adjusting seat 5 in the width direction of the installation position. Such a design simplifies the structure of the coating die head, reduces the number of components and installation steps, and improves the manufacturing efficiency and convenience of the coating die head. Simplifying the installation position of the blocking block 1 locking screw 54 for locking the adjusting rod 2 on the adjusting seat 5 also helps to reduce the manufacturing cost of the coating die head. Since the blocking block 1 locking screw 54 for locking the adjusting rod 2 on the adjusting seat 5 is directly installed in the mounting groove 53 at the bottom of the adjusting rod 2, the locking screw 54 for locking the adjusting rod 2 on the adjusting seat 5, and the locking screw 54 for locking the adjusting rod 2 on the adjusting seat 5, no additional independent installation parts are required, which can save material and processing costs.

[0053] like Figure 8As shown, in this embodiment, the overlapping portion 11 has a first inclined surface 111 and a second inclined surface 112. When the blocking block 1 locking screw 54 is used to lock the adjusting rod 2 on the adjusting seat 5 and overlaps each other, the first inclined surface 111 locking screw 54 is used to lock the adjusting rod 2 on the adjusting seat 5 and the second inclined surface 112 locking screw 54 is used to lock the adjusting rod 2 on the adjusting seat 5. The locking screw 54 is used to lock the adjusting rod 2 on the adjusting seat 5. The avoidance design of the locking screw 54 is used to lock the adjusting rod 2 on the adjusting seat 5 allows them to be slightly offset or adjusted in position when overlapping each other without the need for completely accurate alignment. Such an avoidance design can allow a certain adjustment margin, making the assembly of the blocking block 1 locking screw 54 for locking the adjusting rod 2 on the adjusting seat 5 more flexible and easy.
