Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, and more specifically, to an installation structure of a knife pad for a coating machine die head and a coating die head thereof. Background Art

[0002] The knife pad installation technology in the coating film industry has always been a key link in the production process, which directly affects the product quality and production efficiency. At present, the commonly used knife pad installation methods in the industry mainly rely on internal positioning pins and external positioning pins for fixation. Although these two methods can achieve the basic positioning of the knife pad, there are many limitations and challenges in actual operation.

[0003] First of all, the fixed method of internal positioning pins can provide better positioning accuracy and stability in the initial stage. However, with the multiple repairs and uses of the die head, the reference dimensions of the die head will change slightly, resulting in a decrease in the matching degree between the knife pad and the die head. In this case, the internal positioning pins may not be able to accurately position the knife pad, thus affecting the surface density adjustment and the size control of the coating area during the coating process, and further reducing the product quality.

[0004] Secondly, when the size of the die head changes and the internal positioning pins are no longer applicable, using external positioning pins to fix the knife pad becomes a helpless choice. However, the installation of external positioning pins not only poses higher requirements for the technical level of operators, but also significantly increases the error rate during the installation process. Due to the difficulty of fine adjustment of the positioning pin position, it often requires repeated debugging to reach a satisfactory matching state, which not only prolongs the on-site debugging time, but also increases the material loss, thus increasing the production cost. More seriously, after multiple installation failures, in order to adapt to the changed die head size, it is necessary to re-customize the knife pad, further exacerbating the cost burden and time waste.

[0034] In view of the problem that the amount of inward shrinkage of the cutter pad during installation is not easy to control due to the die head size problem, the present application proposes an installation structure for the cutter pad on the die head of a coater and its coating die head. This installation structure can accurately adjust the amount of inward shrinkage of the cutter pad and is easy to operate.

[0035] The following will detail a die head cutter pad installation structure and a coating die head of the present application through the following embodiments.

[0036] It can be understood that the amount of inward shrinkage of the cutter pad 30 is the amount of inward shrinkage of the cutter pad 30 relative to the die head lip after the cutter pad 30 is installed between the upper die head 10 and the lower die head 20.

[0037] Embodiment 1:

[0038] As Figures 1-4 shown, in this embodiment, a die head cutter pad 30 installation structure includes: a mounting frame 100, which serves as the basic support for the entire adjustment structure and ensures the stable installation of the differential head 200 and the reference block 300; a differential head 200, which is arranged on the mounting frame 100; and a reference block 300, which is arranged on the rod portion of the differential head 200;

[0039] Among them, the tool pad 30 is arranged on the reference block 300, and the reference block 300 is used to carry the tool pad 30. By adjusting the micrometer head 200, the reference block 300 drives the tool pad 30 to move, so as to adjust the retraction amount of the tool pad 30 when the tool pad 30 and the die head are installed.

[0040] The micrometer head 200 is a precision measuring tool, which is often used in occasions that require high-precision measurement and adjustment. It usually includes a rod part with a precision thread, and the pitch of this thread is very small, usually 0.5 mm or less. The micrometer head 200 has a rotatable handwheel. The rotation of the handwheel drives the rod part to move forward or backward, so that the distance can be measured or adjusted very precisely. The principle of the micrometer head 200 is based on the spiral amplification effect, that is, when the handwheel rotates one circle, the rod part only moves forward or backward by the distance of one pitch. To further improve the accuracy, there are usually smaller scales on the handwheel. These scales represent the angle less than one circle of the handwheel rotation, and then are converted into smaller distance units, such as one thousandth of a millimeter (0.001 mm).

[0041] By fixing the micrometer head 200 on the mounting bracket 100, and then penetrating and connecting its rod part to the reference block 300. When the operator rotates the handwheel of the micrometer head 200, the rod part will generate a small but precise linear displacement along the axial direction. This displacement will be transmitted to the reference block 300, and the reference block 300 will move accordingly, thereby driving the tool pad 30 to adjust in the front-back direction, and realizing the precise control of the retraction amount of the tool pad 30.

[0042] By integrating the micrometer head 200 on the die head tool pad 30, the problem of precision control during the installation of the tool pad 30 is effectively solved.

[0043] In this embodiment, it should be noted that the mounting bracket 100 is in an L-shaped structure and is divided into a horizontal plate 110 and a side plate 120; the micrometer head 200 is arranged on the side plate 120, and its rod part passes through the side plate 120 and is connected to the reference block 300; the reference block 300 is slidably arranged on the lower end surface of the horizontal plate 110.

[0044] Embodiment Two:

[0045] This embodiment is a further improvement based on Embodiment One.

[0046] As Figure 1 、 Figure 2 and Figure 4 shown, in this embodiment, the reference block 300 and the tool pad 30 are connected by a first positioning pin 400. The tool pad 30 is fixed on the reference block 300 through the first positioning pin 400 to facilitate installation and disassembly.

[0047] Specifically, there are vertically downwardly opened bolt holes on the upper end surface of the reference block 300, and vertically upwardly opened pin holes on the lower end surface of the reference block 300. The bolt holes communicate with the pin holes;

[0048] Among them, a fastening bolt 500 is arranged in the bolt hole. The first positioning pin 400 has an internal thread adapted to the external thread on the fastening bolt 500. After the first positioning pin 400 is inserted into the pin hole, it is threadedly connected to the fastening bolt 500. The tool pad 30 is arranged between the first positioning pin 400 and the reference block 300.

[0049] Through the combination of the first positioning pin 400 and the fastening bolt 500, the installation and disassembly process of the tool pad 30 becomes simple and fast. The staff only needs to screw in or out the fastening bolt 500 to complete the fixation or release of the tool pad 30, which greatly saves the time consumed due to the replacement of the tool pad 30 on the production line.

[0050] In this embodiment, it should be noted that the tool pad 30 is provided with a hole. The first positioning pin 400 passes through the hole on the tool pad 30 from bottom to top, and then is inserted into the pin hole and threadedly connected to the fastening bolt 500, so that the tool pad 30 is fixed on the reference block 300.

[0051] Embodiment Three:

[0052] This embodiment is a further improvement based on Embodiments One and Two.

[0053] As Figures 1-4 shown, this embodiment proposes a coating die head, including an upper die head 10, a lower die head 20, and a tool pad 30 arranged between the upper die head 10 and the lower die head 20; among them, it further includes: the installation structure of the die head tool pad 30 in Embodiments One and Two.

[0054] Specifically, the mounting bracket 100 is arranged on the side surface of the upper die head 10 or the lower die head 20, and the side end of the tool pad 30 is connected to the reference block 300.

[0055] Since the tool pad 30 moves in the front-back direction (the front-back direction is the Figure 1 X direction in Figure 1 ), the installation structure of the die head tool pad 30 is installed on the left and right side surfaces of the upper die head 10 or the lower die head 20 (the left and right side surfaces of the upper die head 10 are the Figure 1 side surfaces of the upper die head 10 in the Y direction in the schematic diagram, and the left and right side surfaces of the lower die head 20 are the side surfaces of the lower die head 20 in the Y direction in the schematic diagram) to realize the adjustment of the position of the tool pad 30.

[0056] In order to enable the tool pad 30 to move smoothly, there are two sets of installation structures for the die head tool pad 30, which are respectively installed on the left and right sides of the upper die head 10, or respectively arranged on the two sides of the two lower die heads 20; then the two ends of the tool pad 30 are respectively arranged on two reference blocks 300 of the two sets of die head tool pad 30 installation structures.

[0057] It should be noted that the mounting bracket 100 is fixedly arranged on the upper die head 10 or the lower die head 20 through the second positioning pin 130.

[0058] Specifically, mounting holes are formed in the cross plate 110, and the second positioning pin 130 is connected to the upper die head 10 or the lower die head 20 after passing through the mounting holes, so as to fix the cross plate 110 on the upper die head 10 or the lower die head 20. This design facilitates the installation and disassembly of the mounting bracket 100.

[0059] To ensure the stability of the mounting bracket 100 on the upper die head 10 or the lower die head 20, the mounting bracket 100 is fixed by at least two or more second positioning pins 130.

[0060] The above has described the embodiments of the present disclosure. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, the practical application or the improvement of the technology in the market, or to enable other ordinary technical personnel in the technical field to understand the embodiments disclosed herein.
