Description

Technical Field

[0001] The present application relates to the field of coating die heads, and in particular to a coating die head flow regulating mechanism. Background Art

[0002] A gluing adjustable die head is disclosed in the prior art, and its publication number is CN 113680605 A, and its publication date is 2021.11.23. The coating thickness adjustment mechanism of the gluing adjustable die head includes a coating differential head fixed on the top of the upper die head, a coating connecting rod connected to the coating differential head, and an adjustment strip connected to the bottom end of the coating connecting rod. Specifically, the adjustment strip is integrally formed with the coating connecting rod; the adjustment strip is located between the slurry distribution chamber and the lip, and the coating differential head drives the adjustment strip to move vertically through the coating connecting rod. The coating thickness adjustment mechanism drives the adjustment strip up and down by the coating differential head to adjust the height of the slit through which the slurry passes, thereby adjusting the thickness of the coating.

[0003] The prior art uses a coating micrometer to adjust the thickness of the coating, and the micrometer is an adjustment device of the micrometer. Since the micrometer is a standard part of the micrometer, the disadvantages of using the micrometer to adjust the thickness of the coating are:

[0004] (1) Therefore, the size of the differential head will affect the length of the baffle block. When multiple sets of coating thickness adjustment mechanisms are arranged side by side, the larger the size of the differential head, the longer the length of the baffle block. Because a clearance is required between two adjacent baffle blocks, the length of the baffle block cannot be shortened. When one of the baffle blocks is adjusted, the adjustable flow cross-sectional area is also relatively large, making it impossible to achieve more precise flow regulation.

[0005] (2) The traditional T-type flow block and differential head structure is relatively large, especially when multiple flow blocks and differential heads are required, they will occupy a large space. This may restrict the layout and installation of other components, especially when space is limited. Utility Model Content

[0006] The purpose of the present application is to provide a coating die head flow regulation mechanism that achieves more precise flow regulation, greatly improves the flow control accuracy, and makes the coating surface density more uniform.

[0007] In order to achieve the above objectives, this application provides the following technical solutions:

[0008] A coating die flow regulating mechanism comprises a baffle block, an adjusting rod, and an adjusting drive device, wherein the baffle block is mounted at one end of the adjusting rod, and the adjusting drive device is arranged at the other end of the adjusting rod. The adjusting drive device can adjust the flow of the coating die head by driving the baffle block through the adjusting rod. The adjusting drive device comprises an adjusting screw and a mounting seat, wherein the adjusting screw is rotatably mounted on the mounting seat, and the mounting seat is used to limit the up and down movement of the adjusting screw. The threaded end of the adjusting screw is threadedly connected with the threaded hole of the adjusting rod, and the adjusting screw can drive the adjusting rod to drive the baffle block to perform lifting movement through the cooperation between the threaded end and the threaded hole of the adjusting rod.

[0009] Furthermore, the head of the adjusting screw is provided with an annular scale.

[0010] Furthermore, the mounting seat is provided with a first limit groove, a second limit groove, a third mounting groove, a fourth limit groove and an adjustment groove, the first limit groove cooperates with the guide portion of the adjusting rod to guide the adjusting rod when it is raised or lowered, the second limit groove cooperates with the head of the adjusting rod to limit the lifting height of the adjusting rod, the third mounting groove is used to install the threaded portion of the adjusting screw, the fourth limit groove limits the up and down movement of the adjusting screw, and the adjustment groove corresponds to the head of the adjusting screw.

[0011] Furthermore, a fourth mounting groove is provided at the bottom of the adjusting rod, and the baffle block is installed in the fourth mounting groove.

[0012] Furthermore, a lap joint is provided on the side of the baffle block, and two baffle blocks are overlapped with each other via the lap joint.

[0013] Furthermore, a first inclined surface and a second inclined surface are provided on the overlapping portion.

[0014] Furthermore, the width of the baffle block is smaller than the diameter of the adjusting rod.

[0015] Furthermore, the distance between the two adjusting rods is 30 mm to 10 mm.

[0016] Furthermore, the distance between the two adjusting rods is 13.4 mm.

[0017] The beneficial effects of this application are:

[0018] When adjusting the present application, the adjusting screw is rotated, and the adjusting screw can drive the adjusting rod to move up and down through the threaded end and the threaded hole of the adjusting rod, thereby realizing the adjustment of the coating flow. Compared with the prior art that uses a differential head to adjust the flow, the present application has a simpler structure, and the size of the adjusting screw is much smaller than that of the differential head. Since the installation space of the adjusting screw is small, a smaller sized flow block can be set. A smaller sized flow block can make the adjustable flow cross-sectional area of ​​the coating flow smaller, thereby realizing more precise flow regulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] 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.

[0033] like Figure 1 and Figure 2 As shown, a coating die flow regulating mechanism includes a baffle block 1, an adjusting rod 2, and an adjusting drive device 3. The baffle block 1 is installed at one end of the adjusting rod 2, and the adjusting drive device 3 is arranged at the other end of the adjusting rod 2. The adjusting drive device 3 can drive the baffle block 1 through the adjusting rod 2 to adjust the flow of the coating die. The adjusting drive device 3 includes an adjusting screw 31 and a mounting seat 32. The adjusting screw 31 is rotatably mounted on the mounting seat 32, and the mounting seat 32 is used to limit the up and down movement of the adjusting screw 31. The threaded end 311 of the adjusting screw 31 is threadedly connected with the threaded hole 21 of the adjusting rod 2. The adjusting screw 31 can drive the adjusting rod 2 to drive the baffle block 1 to move up and down through the threaded end 311 and the threaded hole 21 of the adjusting rod 2.

[0034] When adjusting the present application, by rotating the adjusting screw 31, the adjusting screw 31 cooperates with the threaded hole 21 of the adjusting rod 2 through the threaded end 311 to drive the adjusting rod 2 to drive the baffle block 1 to move up and down, thereby realizing the adjustment of the coating flow rate. Compared with the prior art that uses a differential head to adjust the flow rate, the structure of the present application is simpler, and the size of the adjusting screw 31 is much smaller than that of the differential head. Since the installation space of the adjusting screw 31 is small, a smaller baffle block 1 can be set. The smaller baffle block 1 can make the adjustable flow cross-sectional area of ​​the coating flow smaller, thereby realizing more precise flow regulation.

[0035] In addition, when the traditional T-shaped baffle block 1 is installed on the die head, since the width of the T-shaped baffle block 1 is greater than the adjusting rod 2, silicone foam needs to be set at the connection between the T-shaped baffle block 1 and the adjusting rod 2. The purpose of setting the silicone foam is to prevent the slurry from squeezing into the installation position of the adjusting rod 2 of the die head when the T block moves up and down.

[0036] like Figure 3As shown, in this embodiment, the head of the adjusting screw 31 is sleeved with an annular scale 4. The annular scale 4 is located around the head of the adjusting screw 31 so that the scale lines can be clearly seen. In this way, the operator can directly observe the marks on the scale to understand the current position of the screw, thereby making adjustments more convenient. The design of the annular scale 4 can generally provide higher adjustment accuracy. Compared with ordinary linear scales, the annular scale 4 has denser scale lines and can more accurately indicate the position of the adjusting screw 31. The annular scale 4 can provide a repeatable adjustment function. By remembering or recording the position on the scale, the operator can quickly adjust the screw to the previous position when needed, thereby avoiding repeated adjustment processes.

[0037] like Figure 4 As shown, in this embodiment, the mounting seat 32 is provided with a first limiting groove 321 , a second limiting groove 322 , a third mounting groove 323 , a fourth limiting groove 324 and an adjusting groove 325 .

[0038] The first limiting groove 321 cooperates with the guide portion 22 of the adjusting rod 2 to provide a guiding function when the adjusting rod 2 is raised or lowered. This helps to ensure that the moving direction of the adjusting rod 2 is stable, avoids deviation or skew, and makes the flow rate regulation of the coating die head more accurate and reliable.

[0039] The second limiting groove 322 cooperates with the head 23 of the adjusting rod 2 to limit the lifting height of the adjusting rod 2. This ensures that the flow block 1 of the coating die head moves within a certain height range to avoid exceeding the design range, thereby ensuring that the coating flow rate is adjusted within a reasonable range.

[0040] The third mounting groove 323 is used to mount the threaded portion of the adjusting screw 31 , so that the adjusting screw 31 can be tightly connected to the mounting seat 32 and is not easy to loosen, thereby improving the stability and reliability of the adjusting mechanism.

[0041] In this embodiment, a fourth mounting groove is provided at the bottom of the adjusting rod 2, and the spoiler 1 is mounted in the fourth mounting groove. The split structure allows for more flexible replacement, adjustment or repair of the spoiler 1. When the spoiler 1 needs to be replaced, only the spoiler 1 in the fourth mounting groove needs to be replaced, without replacing the entire adjusting rod 2, which is more convenient and saves costs.

[0042] The split flow regulating mechanism can manufacture the regulating rod 2 and the flow block 1 separately, and the processing of each component is relatively independent, which may reduce some manufacturing complexity and difficulty. At the same time, the split structure allows more flexible selection of different flow blocks 1 and regulating rods 2 for combination to meet different coating requirements.

[0043] like Figure 5As shown, in this embodiment, the side of the baffle block 1 is provided with an overlap portion 11, and the two baffle blocks 1 are overlapped with each other through the overlap portion 11. The existence of the overlap portion 11 increases the sealing between the baffle blocks 1. When the baffle blocks 1 are overlapped together, the overlap portion 11 can effectively prevent the paint from overflowing and leaking, ensuring that the coating process is more stable and controllable. Through the design of the overlap portion 11, the paint can be prevented from leaking from the connecting gap between the baffle blocks 1. This is very important for coating applications that require precise flow control, preventing unnecessary waste of paint and uneven coating. The existence of the overlap portion 11 can make the two baffle blocks 1 closely connected, ensure the continuity and streamline of the paint flow, help optimize the coating effect, and make the coating more uniform and accurate. The setting of the overlap portion 11 can enhance the structural stability of the baffle block 1. The connection method of the overlap portion 11 makes the two baffle blocks 1 more firmly fixed together, preventing loosening due to vibration or other factors during the coating process.

[0044] like Figure 5 As shown, in this embodiment, the overlap portion 11 is provided with a first inclined surface 111 and a second inclined surface 112. By providing the first inclined surface 111 and the second inclined surface 112 on the overlap portion 11, it is ensured that the baffle block 1 will not collide or interfere when overlapping, and it is ensured that the baffle block 1 will not conflict with the upper die when installed on the upper die. This is very important for the stability of the coating die head and the coating effect, making the coating process safer and more reliable

[0045] like Figure 6 As shown, in this embodiment, the width H of the spoiler block 1 is smaller than the diameter D of the adjusting rod 2. By designing the width of the spoiler block 1 to be smaller than the diameter of the adjusting rod 2, the spoiler block 1 can be installed on the adjusting rod 2 more compactly and occupy less space. In this way, the space required to be reserved for the upper die head when installing the spoiler block 1 can be reduced, saving the processing cost and material consumption of the upper die head.

[0046] like Figure 7 As shown, in this embodiment, the distance K between the two adjusting rods 2 is 30 mm to 10 mm.

[0047] In this embodiment, the distance K between the two adjusting rods 2 is 13.4 mm.

[0048] In this embodiment, the spacing K between the two upper adjustment rods 2 is 13.4 mm. When the spacing between the two upper adjustment rods 2 is smaller, it means that the length of the upper mold baffle block 1 is smaller, so that the flow rate in this area can be adjusted in a smaller range, thereby improving the adjustment accuracy.
