[0002] In the field of coating technology, the coating die head is one of the core components of coating equipment, and its function is to uniformly coat the substrate surface with slurry. The coating die head has a slurry cavity inside for slurry flow channels, and the end of the cavity is a precision die lip. During production, especially when changing slurry types or during maintenance shutdowns, some slurry inevitably remains in the slurry cavity.

[0003] Traditional methods for cleaning these residual slurries usually require the complete disassembly of the entire die head. This disassembly and cleaning method has many drawbacks: First, the operation is cumbersome, time-consuming, and labor-intensive, seriously affecting production efficiency; second, frequent disassembly and assembly can easily cause mechanical damage to the high-precision die head, especially the die lip, affecting the uniformity of coating and shortening the service life of the equipment; third, if the cleaning is not thorough, the residual slurry will solidify and dry due to prolonged retention, producing agglomerated particles. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a coating die head and coating equipment, which solves the problems of low efficiency, easy damage to equipment and incomplete cleaning caused by the need to disassemble the die head in traditional cleaning methods.

[0005] This utility model also provides a coating die head as described above, comprising: a die head cover and a cleaning assembly.

The push plate is slidably connected inside the slurry mold cavity, and the adapters extend outside the die head body and are detachably connected to the second sealing cap. This assembly can automatically clean the slurry mold cavity, prevent slurry residue and blockage, and improve the service life and coating quality of the die head.

[0006] According to the coating die head of this utility model, a take-up roller is rotatably connected inside the wire box. Return springs are fixedly connected to both sides of the take-up roller and are fixedly connected to the inner wall of the wire box. Wires are wound on the take-up roller and the wires extend out of the threaded sleeve, which can automatically take up and release the wires, keep the wires neat, avoid tangling and damage, and improve the safety and ease of use of the equipment.

[0007] According to the coating die head of this utility model, a limiting plate can be detachably installed on the end face of the wire, and the limiting plate is larger than the inner diameter of the threaded sleeve to prevent the wire from being pulled out excessively or falling off, ensuring stable and reliable electrical connection and reducing the risk of failure.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Reference Figure 1-4 This utility model discloses a coating die head and coating equipment, including: a die head cover 1 and a cleaning component 2. The bottom of the die head cover 1 is fixedly connected to a die head body 101. The die head body 101 has a slurry mold cavity 105 for containing slurry. The bottom of the slurry mold cavity 105 has a liquid outlet hole. A liquid outlet pipe 102 is fixedly connected to one side of the die head body 101. The liquid outlet pipe 102 is connected to the liquid outlet hole and is used to transport slurry into the slurry mold cavity 105. The end of the liquid outlet pipe 102 is detachably connected to a first sealing cap 103 by a thread. The liquid outlet pipe 102 can be sealed in the non-cleaning state. A die lip gap 104 for slurry outflow is also machined on one side of the bottom of the die head body 101.

[0018] The cleaning component 2 is used to clean residual slurry in the slurry mold cavity 105. Its core includes a push plate 201, an electric push rod 204, and an electrical box 205. The push plate 201 is slidably connected to the inside of the slurry mold cavity 105, and a cleaning brush 2011 is fixedly installed around its outer periphery. The cleaning brush 2011 is in close contact with the inner wall of the slurry mold cavity 105. A heating wire 2012 is embedded inside the push plate 201 to heat and soften the slurry for easy cleaning.

[0019] Two adapters 202 are fixedly connected to one side of the push plate 201. The adapters 202 are made of conductive material. One of the adapters 202 is electrically connected to the internal heating wire 2012 to supply power to it. Both adapters 202 extend to the outside of the mold head body 101. In the non-working state, the exposed ends of the two adapters 202 are detachably connected to a second sealing cover 203 by threads to provide sealing and protection.

[0020] When cleaning is required, remove the second sealing cover 203, and detachably connect the first of the two adapters 202 to the threaded push rod 2041 of the electric push rod 204 via threads; detachably connect the second adapter 202 to the threaded sleeve 2051 of the electrical box 205 via threads.

[0021] Inside the wire box 205, a take-up roller 206 is rotatably mounted. Both ends of the take-up roller 206 are fixedly connected to the inner wall of the wire box 205 via return springs 207, enabling the take-up roller 206 to have an automatic take-up function. A wire 208 is wound on the take-up roller 206.

The other end of the wire 208 extends out of the wire box 205 for connecting to an external power supply device. At the end of the wire 208 that passes through the threaded sleeve 2051, a limiting plate is fixedly installed. The size of the limiting plate is larger than the inner diameter of the threaded sleeve 2051 to prevent the wire 208 from being excessively pulled into the die head.

[0022] Specifically, two sets of cleaning components 2 can be set and symmetrically installed on both sides of the mold head body 101 so as to clean the slurry mold cavity 105 from two directions and improve cleaning efficiency.

[0023] Specifically, the electric actuator 204 can be a commonly used small linear electric actuator, and its thrust can be selected according to the viscosity of the slurry, such as a standard model of 50N to 200N. The heating wire 2012 can be a common nickel-chromium alloy resistance wire, and the return spring 207 is a spiral spring.

[0024] Working principle: During conventional coating operations, the slurry mold cavity 105 is sealed by the push plate 201 and the second sealing cover 203. When cleaning is required, the second sealing cover 203 is removed, and the electric push rod 204 and the wiring box 205 are respectively installed on the corresponding adapters 202. The external power supply equipment is started, and the heating wire 2012 is powered through the wire 208 and the adapter 202 to heat and soften the solidified slurry. At the same time, the electric push rod 204 is started, and its threaded push rod 2041 pushes the push plate 201 to slide in the slurry mold cavity 105. The cleaning brush 2011 on the push plate 201 scrapes and cleans the residual slurry on the inner wall of the cavity. The cleaned slurry is finally discharged from the mold lip gap 104, thereby achieving efficient and thorough cleaning.
