Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of protective coating manufacturing, in particular to a thermal response protective coating gradient structure composite forming equipment. BACKGROUND

[0002] The thermal response protective material system includes a micro-nano porous thermal buffer layer, an amorphous-crystalline composite ceramic conversion layer, and a radiation heat reflection functional layer.

The permanent magnet ferrite ball milling equipment pours the corresponding raw materials into the inside of the feed inlet, starts the motor and cooperates with the first chain belt and the second chain belt, so that the two sides of the crushing roller and the shaft rotate at the same time, thereby crushing the raw materials.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-6As shown, a thermal response protective coating gradient structure composite molding equipment proposed by the present invention includes a processing frame 1, and a ball milling assembly 3 is arranged on the top of the processing frame 1. It is explained here that if the material is heavy, a fifth motor can be installed between the processing frame 1 and the ball milling assembly 3. The fifth motor is fixedly installed on one side of the processing frame 1. The fifth motor drives the ball milling assembly 3 to rotate along the processing frame 1, and uses gravity to push and advance the material. A gas filling assembly 2 is provided on one side of the ball milling assembly 3, and a driving assembly 4 is provided on one side of the processing frame 1. The ball milling assembly 3 and the driving assembly 4 are arranged in a linkage state. The ball milling assembly 3 includes a first ring cavity frame 301, a second ring cavity frame 302 and a third ring cavity frame 303 arranged on the top of the processing frame 1. The first ring cavity frame 301 is internally rotatably mounted with a first gear 304, the second ring cavity frame 302 is internally rotatably mounted with a second gear 305, the third ring cavity frame 303 is internally rotatably mounted with a third gear 306, the first gear 304 extends to one side of the first ring cavity frame 301 and is fixedly mounted with a first ball milling frame 307 through a positioning rod 311, the second gear 305 extends to one side of the second ring cavity frame 302 and is fixedly mounted with a second ball milling frame 308 through a positioning rod 311, the third gear 306 extends to one side of the third ring cavity frame 303 and is fixedly mounted with a third ball milling frame 309 through a positioning rod 311, and the gas filling assembly 2 includes a gas filling assembly 202 inserted into the first ring cavity frame 30 1. A sealing protection frame 201 on one side, a second motor is fixedly installed inside the sealing protection frame 201, a positioning long rod 203 is fixedly installed on the output shaft of the second motor, a transposition clamping frame 204 is fixedly installed on the outside of the positioning long rod 203, and both sides of the transposition clamping frame 204 are rotatably installed with a limited rotation frame 205, and an arc-shaped guide rod 206 is fixedly installed on the bottom of the limited rotation frame 205. A third motor is fixedly installed on the inner wall of the arc-shaped guide rod 206, and a bidirectional clamping rod 207 is rotatably installed on the side of the arc-shaped guide rod 206 away from the third motor. A guide long rod 209 is rotatably installed on the inner wall of the sealing protection frame 201, and a hollow clamping tube 208 is fixedly installed on the outside of the guide long rod 209. An auxiliary clamping frame 210 is rotatably installed inside the clamping tube 208, and a conductive fan blade 211 is installed on one side of the auxiliary clamping frame 210 through the rotation of the fourth motor. Since the thermally responsive protective coating gradient structure contains a large amount of small-particle powdered material, it is easy to generate friction during grinding and adhere to the inner walls of the first ball mill frame 307, the second ball mill frame 308 and the third ball mill frame 309, preventing smooth running-in. Therefore, the staff pulls open the sealing protection frame 201 under the limit between the first ring cavity frame 301 and the limit connection block 202, and transports the material into the interior of the first ball mill frame 307. Then, the sealing protection frame 201 is merged with the first ring cavity frame 301, and a sealing ring is set between the two to improve the sealing performance.

[0032] The fourth motor drives the conductive fan blade 211 to form an airflow to push the materials into the first ball mill frame 307, the second ball mill frame 308 and the third ball mill frame 309. At the same time, due to the pushing of the airflow, the materials will not flow back toward the sealing protection frame 201 to cause interference. Under the pushing of the airflow and the influence of the rotating force of the ball mill, the materials are spread under each separation hole along the first ball mill frame 307, the second ball mill frame 308 and the third ball mill frame 309, thereby improving the separation efficiency. A gas conveying device is provided inside the sealing protection frame 201. Under the influence of the gas conveying device, the materials can be A carrier gas, such as nitrogen, is introduced into the material to form a high-hardness bottom layer. The gas composition can also be switched, such as introducing an aerosol containing a ceramic precursor to form a ceramic coating on the surface through chemical vapor deposition and ball milling. Under the influence of the wind force of the conductive fan 211, the material and the gas can be fully mixed. At the same time, the second motor is a forward and reverse motor. The second motor drives the positioning rod 203 to rotate in the forward or reverse direction along the sealing protection frame 201. Two sets of arc-shaped guide rods 206 are rotatably installed on both sides of the bidirectional clamping rod 207. One set of arc-shaped guide rods 206 and the limiting rotating frame 20 are connected. 5 is connected, and the other set of arc-shaped guide rods 206 is fixedly connected to the auxiliary clamping frame 210. Since the connection between the two-way clamping rod 207, the arc-shaped guide rod 206 and the hollow clamping tube 208 is a hollow sphere, the arc-shaped guide rod 206 and the hollow clamping tube 208 rotate in the two-way clamping rod 207. The sealing protection frame 201 drives the two-way clamping rod 207 on one side to move forward through the arc-shaped guide rod 206, and the two-way clamping rod 207 on the other side moves backward. Then, the auxiliary clamping frame 210 drives the conductive fan blade 211 to swing left and right along the hollow clamping tube 208. At the same time, the third The motor is also a forward and reverse motor. The third motor drives the limiting rotating frame 205 to rotate along the transposition clamping frame 204. The limiting rotating frame 205 first drives the bidirectional clamping rod 207 to deflect up and down through the arc guide rod 206. The bidirectional clamping rod 207 drives the hollow clamping tube 208 and the guide long rod 209 to deflect up and down along the inner wall of the sealing protection frame 201 through the auxiliary clamping frame 210, so that the conductive fan blade 211 can be adjusted in position in all directions, thereby causing the ball mill assembly to be pushed by air pressure in all directions, avoiding material residue and improving processing efficiency.

[0033] like Figure 1As shown, the driving assembly 4 includes a first motor 401 fixedly mounted on the top of the processing frame 1, a first gear 402 is fixedly mounted on the output end of the first motor 401, a transmission rod 405 is fixedly mounted inside the first gear 402, a second gear 403 is fixedly mounted on the outside of the transmission rod 405, a third gear 404 is fixedly mounted on the outside of the transmission rod 405, the third gear 404 is meshed with the third gear teeth 306, the second gear 403 is meshed with the third gear teeth 306, and the first gear teeth 304 are meshed with the first gear 402. The first motor 401 drives the first gear 402, the third gear 404 and the second gear 403 to rotate simultaneously through the transmission rod 405, and the gears of the first gear 402, the second gear 403 and the third gear 404 are changed from large to small, and the corresponding gear sizes of the first gear teeth 304, the second gear teeth 305 and the third gear teeth 306 are changed from small to large, so that the third gear teeth 306, the second gear teeth 305 and the first gear teeth 304 maintain the same rotation speed, avoiding excessive difference in rotation speed, so that large quantities of materials are kept at a uniform speed for running-in, thereby improving the accuracy of material grinding.

[0034] like Figure 3-Figure 8 As shown, the processing area of ​​the first ball mill frame 307 is the coarse grinding area, the processing area of ​​the second ball mill frame 308 is the medium grinding area, and the processing area of ​​the third ball mill frame 309 is the fine grinding area. According to different processing areas and different material requirements, the material is processed. A second transmission cavity 313 is provided between the first ball mill frame 307 and the second ball mill frame 308, and a first transmission cavity 312 is provided between the second ball mill frame 308 and the third ball mill frame 309. The first ring cavity frame 301 and the second ring cavity frame 309 are connected to each other. 02 and the bottom of the third ring cavity frame 303 are fixedly installed with a sealable material transfer rack 310, and the processing rack 1 is located directly below the first ring cavity frame 301, the second ring cavity frame 302 and the third ring cavity frame 303, and a layered collection rack is fixedly installed. An auxiliary fan blade 314 is rotatably installed on the outer side of the positioning rod 311, and the materials processed by the first ring cavity frame 301, the second ring cavity frame 302 and the third ring cavity frame 303 can be collected in layers by the layered collection rack and transported to the next processing area of ​​each.

[0035] In this embodiment, the material is first ball milled in the first ball milling frame 307, and the ball-milled material is the primary material. After processing, the primary material can be pushed into the second ball milling frame 308 by the wind force of the conduction fan blade 211, and the auxiliary fan blade 314 can be rotated along the clamping rod 311 under the guidance of the wind force. The auxiliary fan blade 314 under rotation pushes the primary material that may be accumulated around the clamping rod 311, and also assists in the transmission of the gas flow transmitted from the gas filling assembly 2, guides the gas, and ball mills the material in the second transmission cavity 313 into the second ball milling frame 308 to form the medium material. Similarly, the material in the first transmission cavity 312 enters the third ball milling frame 309 for fine processing, so that batch processing is performed according to the different material requirements of the thermal response protective coating gradient structure, and the overall work efficiency and fine grinding power are improved.
