Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically to a coating die head gasket. Background Technology

[0002] The extrusion coating die is a key component of an extrusion coating machine. Its main function is to uniformly extrude coating material onto the substrate to form a high-quality coating. The design of the die is crucial; it must have an appropriate structure and shape to effectively eliminate air bubbles in the coating and ensure a defect-free coating. The die typically features vents or discharge channels to allow air bubbles to escape smoothly. Additionally, the die surface undergoes special treatments, such as a smoothing process, to reduce coating adhesion and further prevent air bubble formation.

[0003] In extrusion coating dies, die shims also play a crucial role. Die shims are primarily used to adjust the gap between the die and the substrate to ensure the thickness and uniformity of the coating. By adjusting the shim thickness, the dimensions of the coating can be precisely controlled to meet different production requirements. In the extrusion coating process, selecting appropriate die shims is essential for improving coating quality and production efficiency.

[0004] Existing extrusion coating dies typically use die head shims of fixed size to ensure a fixed width of coating material flowing out of the die head. However, since different products have different requirements for coating width, it is necessary to prepare shims of various specifications to meet production needs, which leads to a significant increase in inventory costs and also increases the difficulty of procurement and management. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides a coating die head gasket, which can greatly reduce the inventory cost of coating gaskets, while reducing the difficulty of procurement and management.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A coating die gasket includes a gasket base and two quick-change baffles. The two quick-change baffles are detachably installed at both ends of the gasket base. The gasket base and the two quick-change baffles are combined to form a U-shaped structure. Each of the two quick-change baffles has a protrusion on its opposite side, and a discharge channel for accommodating the outflow of coating is formed between the two protrusions.

[0008] As a further improvement to the above technical solution, the quick-change stop edge is engaged with the gasket substrate.

[0009] As a further improvement to the above technical solution, the gasket substrate is provided with a plurality of first mounting holes, and the quick-change stop edge is provided with a second mounting hole.

[0010] As a further improvement to the above technical solution, baffles are provided on the opposite sides of the two protrusions.

[0011] As a further improvement to the above technical solution, the protrusion engages with the baffle.

[0012] As a further improvement to the above technical solution, the protrusion is provided with a dovetail groove, and the baffle is provided with a snap-fit ​​part that cooperates with the dovetail groove.

[0013] As a further improvement to the above technical solution, the gasket substrate is provided with a plurality of mounting grooves at intervals along the length direction. The mounting grooves are used to install quick-release strip blocks, and the ends of the quick-release strip blocks are flush with the ends of the quick-change stop edges.

[0014] As a further improvement to the above technical solution, the mounting groove is a T-shaped groove, and the quick-installation strip block is provided with a T-shaped block that mates with the T-shaped groove.

[0015] As a further improvement to the above technical solution, the quick-installation strip block is provided with a third mounting hole.

[0016] As a further improvement to the above technical solution, the two quick-shift edges are arranged symmetrically along the center of the gasket substrate.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model provides a coating die gasket, which consists of a gasket base and two quick-change baffles. The quick-change baffles are detachably connected to the gasket base. Each of the two quick-change baffles has a protrusion on one side of its opposite side. The distance between the two protrusions on their opposite sides determines the width of the coating fluid flowing out of the coating die. By switching between quick-change baffles of different specifications, specifically, the protrusion length of the protrusions in quick-change baffles of different specifications is different, resulting in different widths of coating fluid flowing out of the coating die. Therefore, by simply changing the quick-change baffles of different specifications, the width of coating fluid flowing out of the coating die can be varied, which can meet the coating width requirements of different products. This can greatly reduce the inventory cost of coating gaskets and reduce the difficulty of procurement and management.

[0019] 2. This utility model provides a coating die gasket. By setting a baffle, the baffle can block part of the paint from flowing out, which can reduce the coating thickness on the product edge, effectively control the product edge bulging phenomenon, significantly improve the coating precision and uniformity of the product edge, and ensure product quality.

[0020] 3. This utility model provides a coating die gasket, which is provided with several mounting grooves for mounting quick-release strip blocks. The ends of the quick-release strip blocks are flush with the ends of the quick-change baffles. The quick-release strip blocks can divide the discharge channel into several small channels, so that the flowing paint forms a blank area in the area corresponding to the quick-release strip block. Thus, it can meet different types of coating effects and improve the applicability of the product. Attached Figure Description

[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0027] Reference Figures 1 to 3 An example of this utility model provides a coating die gasket, including a gasket base 100 and two quick-change baffles 110. The two quick-change baffles 110 are detachably installed at both ends of the gasket base 100. The gasket base 100 and the two quick-change baffles 110 are combined to form a U-shaped structure. Each of the two quick-change baffles 110 has a protrusion 120 on its opposite side, and a discharge channel for accommodating the outflow of coating is formed between the two protrusions 120.

[0028] Understandably, the distance between the two protrusions 120 on opposite sides determines the width of the coating material flowing out of the coating die. Specifically, the protrusion length of the protrusions 120 in different specifications of quick-change baffles 110 is different, resulting in different widths of coating material flowing out of the coating die. Therefore, by simply replacing quick-change baffles 110 with different specifications, the width of coating material flowing out of the coating die can be made to meet the coating width requirements of different products. This can greatly reduce the inventory cost of coating pads, while also reducing the difficulty of procurement and management.

[0029] Furthermore, the quick-change stop 110 is snapped into the gasket base 100, which enables the quick-change stop 110 to be positioned accurately and ensures the stability of the quick-change stop 110 installation.

[0030] Furthermore, the gasket base 100 is provided with a plurality of first mounting holes 130, and the quick-change baffle 110 is provided with second mounting holes 140. Both the first mounting holes 130 and the second mounting holes 140 are used to install with screws, so that the gasket base 100 and the quick-change baffle 110 can be fixed to the coating die head by screws respectively. When it is necessary to replace the quick-change baffle 110, simply remove the screws on the two quick-change baffles 110, and the original quick-change baffle 110 can be removed. Then, a quick-change baffle 110 of the appropriate specification can be installed, and the quick-change baffle 110 can be fixed to the coating die head again by screws, thereby greatly improving the replacement efficiency of the quick-change baffle 110.

[0031] Specifically, the two quick-change edges 110 are symmetrically arranged along the center of the gasket substrate 100, which can ensure that the positions of the two quick-change edges 110 correspond to the edges on both sides of the product, thereby ensuring coating accuracy.

[0032] In some preferred embodiments, baffles 150 are provided on opposite sides of the two protrusions 120. The baffles 150 can block part of the paint from flowing out, reduce the thickness of the coating sprayed on the edge of the product, effectively control the bulging phenomenon at the edge of the product, significantly improve the coating accuracy and uniformity at the edge of the product, and ensure product quality.

[0033] Furthermore, the protrusion 120 engages with the baffle 150, facilitating the installation and removal of the baffle 150 and making it easy to replace baffles 150 of different specifications, thereby enabling precise control of the coating thickness at the product edge.

[0034] Specifically, the protrusion 120 is provided with a dovetail groove 160, and the baffle 150 is provided with a snap-fit ​​part 170 that cooperates with the dovetail groove 160, thereby improving the stability of the baffle 150 and preventing the baffle 150 from shifting or detaching.

[0035] In some preferred embodiments, the gasket substrate 100 is provided with a plurality of mounting grooves 180 at intervals along its length. The mounting grooves 180 are used to install quick-release strip blocks 190. The ends of the quick-release strip blocks 190 are flush with the ends of the quick-change baffles 110. The quick-release strip blocks 190 can divide the discharge channel into a plurality of small channels, so that the outflowing paint forms a blank area in the area corresponding to the quick-release strip blocks 190. Thus, different types of coating effects can be satisfied, and the applicability of the product can be improved.

[0036] It should be noted that multiple mounting slots 180 can be set, and the number and position of quick-installation strip blocks 190 are arranged according to the needs of the product.

[0037] Furthermore, the mounting groove 180 is a T-shaped groove, and the quick-release strip block 190 is provided with a T-shaped block that mates with the T-shaped groove. This ensures that the quick-release strip block 190 is subjected to balanced force, prevents shaking during the spraying process, and guarantees the stability of the coating.

[0038] Furthermore, the quick-release strip block 190 is provided with a third mounting hole 200, which is used to install with screws. After the quick-release strip block 190 is assembled with the gasket base 100, the quick-release strip block 190 is fixed to the coating die head by screws, thereby improving the installation firmness of the quick-release strip block 190.

[0039] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
