DETAILED DESCRIPTION

[0021] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figures 1 to 11 : The ABS material production equipment comprises a frame 1 and a sealed tank 2 installed on the frame 1, wherein a plurality of feed pipes 21 are arranged on the top of the sealed tank 2, a screw extruder 22 is arranged on the bottom of the sealed tank 2, the screw extruder 22 is connected to the bottom of the sealed tank 2 through a connecting pipe 23, an air box 24 is arranged in the sealed tank 2, the feed pipe 21 extends to the bottom of the air box 24, and a plurality of air inlet holes 241 (such as Figure 6 As shown in the figure, the air outlet pipe 242 arranged on the top of the air box 24 extends to the outside of the sealed tank 2; an annular mounting frame 25 is coaxially arranged inside the sealed tank 2, and a plurality of mounting legs 251 are arranged on the peripheral side of the outer wall of the annular mounting frame 25, and the annular mounting frame 25 is fixedly mounted on the sealed tank 2 through the mounting legs 251; a stirring unit 3 is also arranged in the sealed tank 2, and the stirring unit 3 includes a rotating ring 31 rotatably mounted on the annular mounting frame 25, and a plurality of vibrating rods 32 are mounted on the rotating ring 31; the stirring unit 3 also includes a first driving unit 33 that drives the rotating ring 31 to rotate around the axis of the annular mounting frame 25, and the vibrating rod 32 stirs the material when the rotating ring 31 rotates; the stirring unit 3 also includes a second driving unit 34 that drives the vibrating rod 32 to vibrate in the vertical direction, and the second driving unit 34 (as shown in the figure) Figure 8 As shown) drives the vibrating rod 32 to vibrate and exhaust the material.

[0023] When the production equipment in the present application is in use, the multiple feed pipes 21 on the sealed tank 2 are respectively connected to the output ends of the conveying devices of different raw materials, so that the raw materials can directly enter the sealed tank 2 through the feed pipes 21 and be directly conveyed to the bottom of the air box 24. The feed pipe 21 is tightly connected to the output end of the conveying device to prevent gas leakage at the feed pipe 21. The raw materials entering the sealed tank 2 are fully mixed under the action of the stirring unit 3. An air inlet 241 is provided below the air box 24 in the sealed tank 2. Therefore, the gas generated by the raw materials after mixing below the air box 24 can enter the air box 24 through the air inlet 241, and then be discharged through the air outlet pipe 242. The air outlet pipe 242 can be connected to the exhaust device to directly extract the gas generated by the sealed tank 2 and then enter The stirring unit 3 in this embodiment includes a rotating ring 31 rotatably mounted on the annular mounting frame 25 inside the sealed tank 2, and a vibrating rod 32 arranged on the rotating ring 31 can stir the raw materials in the sealed tank 2 when the rotating ring 31 rotates, so that the raw materials are fully mixed. The first driving unit 33 drives the rotating ring 31 to rotate around the axis of the annular mounting frame 25. When the first driving unit 33 stops working, the second driving unit 34 can also drive the vibrating rod 32 to vibrate in the vertical direction. The vibrating rod 32 is inserted into the raw material for vibration, and the mixed gas in the raw material is discharged, thereby reducing the gas content in the ABS raw material and ensuring the quality of the ABS material after molding. The annular mounting frame 25 and the rotating ring 31 in this embodiment are annular, so they will not affect the falling of the raw materials output from the feed pipe 21. The annular mounting frame 25 is fixedly mounted inside the sealed tank 2 through the mounting legs 251 on the circumferential side.

[0024] In order to solve the problem of how the vibrating rod 32 can vibrate the raw materials in the sealed tank 2, the following features are specifically set: The vibrating rod 32 includes a vertical straight rod 321 and an inclined rod 322 connected to the bottom of the straight rod 321. The inclined rod 322 is inclined toward the axis of the sealing tank 2. The straight rod 321 is inserted into the mounting sleeve 311 provided on the rotating ring 31 (such as Figure 4 As shown in the figure, the straight rod 321 is coaxially arranged in the mounting sleeve 311 with a limit block 323, the diameter of the limit block 323 is larger than the diameter of the straight rod 321 and is the same as the inner diameter of the mounting sleeve 311, and springs 312 are arranged at the upper and lower ends of the limit block 323 in the mounting sleeve 311, and the spring 312 elastically connects the mounting sleeve 311 and the limit block 323; an extension rod 324 is coaxially arranged on the top of the limit block 323, and the extension rod 324 extends vertically upward to the upper side of the rotating ring 31, and the extension rods 324 on all the vibrating rods 32 are fixedly connected with a connecting ring 325, and the axis of the connecting ring 325 is on the same straight line as the axis of the rotating ring 31, and the second driving unit 34 drives the connecting ring 325 to vibrate in the vertical direction to drive the vibrating rod 32 to vibrate the material in the sealed tank 2.

[0025] The vibrating rod 32 in this embodiment includes a connected straight rod 321 and an inclined rod 322. The straight rod 321 is inserted into the mounting sleeve 311 of the rotating ring 31. The limit block 323 on the straight rod 321 has the same inner diameter as the mounting sleeve 311, so the stability of the vertical movement path of the vibrating rod 32 can be ensured. Since the inclined rod 322 is inclined, the vibration range of the vibrating rod 32 on the raw material during vibration can be increased, thereby improving the efficiency of vibration exhaust. The spring 312 in the mounting sleeve 311 can In order to cushion the vibrating vibrating rod 32 and prevent the limit block 323 from directly hitting the mounting sleeve 311, the vibrating rod 32 is protected. In this embodiment, a vertical extension rod 324 is provided on the limit block 323 of each vibrating rod 32, and the connecting ring 325 above the rotating ring 31 is fixedly connected to the extension rods 324 of all the vibrating rods 32. Therefore, when the second driving unit 34 drives the connecting ring 325 to reciprocate in the vertical direction, all the vibrating rods 32 can be driven to vibrate at the same time.

[0026] In order to solve the problem of how the second driving unit 34 drives the connecting ring 325 to move in the vertical direction, the following features are specifically set: The second driving unit 34 includes a cam 341, the axis of which is perpendicular to the axis of the sealed can 2 and is arranged horizontally. The cam 341 is located between the rotating ring 31 and the connecting ring 325 (such as Figure 5 As shown in FIG. 1 ), a second shaft rod 342 is coaxially arranged at one end of the cam 341 away from the axis of the sealed can 2. The second shaft rod 342 (as shown in FIG. 1 ) Fig. 9 As shown in the figure, the second driving unit 34 is rotatably mounted on the mounting foot 251 of the annular mounting frame 25 and extends to the outside of the sealed tank 2; the second driving unit 34 also includes a second rotation driver 343, the second rotation driver 343 is mounted on the outside of the sealed tank 2, and the working end of the second rotation driver 343 is transmission-connected to the second shaft 342.

[0027] The second driving unit 34 in the present embodiment includes a second shaft rod 342 rotatably mounted on the annular mounting frame 25, and a cam 341 at one end of the second shaft rod 342. The axes of the cam 341 and the second shaft rod 342 are maintained in the radial direction of the sealing tank 2. When the second rotating driver 343 located outside the sealing tank 2 drives the second shaft rod 342 and the cam 341 to rotate, the circumferential side of the cam 341 fits the lower side of the connecting ring 325. The different positions of the cam 341 contacting the lower side of the connecting ring 325 can drive the connecting ring 325 to change its height position in the vertical direction, thereby driving all the vibrating rods 32 to vibrate in the vertical direction. The second rotating driver 343 in the present embodiment can be a servo motor. The connection between the second shaft rod 342 and the sealing tank 2 is dynamically sealed to prevent the gas in the sealing tank 2 from leaking through the connection between the second shaft rod 342 and the sealing tank 2.

[0028] In order to solve the problem of how the first driving unit 33 drives the rotating ring 31 to rotate around the axis of the annular mounting frame 25, the following features are specifically provided: The first driving unit 33 includes a bevel gear 331, the axis of which is parallel to the axis of the cam 341 (eg Fig. 9 As shown in the figure, the bevel gear 331 is rotatably mounted under the mounting foot 251 of the annular mounting frame 25 through the first shaft 332 and extends to the outside of the sealed tank 2. The first driving unit 33 also includes a first rotating driver 333 that drives the first shaft 332 to rotate around its own axis. A conical gear ring 313 is coaxially mounted on the bottom of the rotating ring 31. The diameter of the conical gear ring 313 is smaller than the inner diameter of the annular mounting frame 25. The conical gear ring 313 is meshed with the bevel gear 331.

[0029] The first driving unit 33 in the present embodiment includes a bevel gear 331 and a first shaft 332. The first rotary driver 333 is located outside the sealed tank 2 to drive the first shaft 332 to rotate. The first shaft 332 drives the bevel gear 331 to rotate. The bevel gear 331 is meshed with the conical gear ring 313 at the bottom of the rotating ring 31. Therefore, when the bevel gear 331 rotates, the conical gear ring 313 and the rotating ring 31 can be driven to rotate synchronously, so that the vibrating rod 32 stirs the raw materials in the sealed tank 2. The rotating ring 31 is limitedly installed on the annular mounting frame 25 to keep the axis position stable during rotation. The conical gear ring 313 is located inside the annular mounting frame 25, so it can be meshed with the bevel gear 331. The first rotary driver 333 in the present embodiment can be a servo motor. The second rotary driver 343 and the first rotary driver 333 can be connected to the second shaft 342 and the first shaft 332 through gears or transmission belts. No more details are given here.

[0030] When the rotating ring 31 rotates, the connecting ring 325 of the vibrating rod 32 rotates synchronously with the rotating ring 31. In order to reduce the friction between the connecting ring 325 and the cam 341, the following features are specifically provided: The cam 341 is located at a side of the mounting sleeve 311 away from the axis of the sealing tank 2 . A plurality of balls 344 are rotatably mounted on the outer wall of the cam 341 . The surfaces of the balls 344 protrude from the outer wall of the cam 341 .

[0031] In this embodiment, a plurality of balls 344 are arranged on the periphery of the cam 341. The cam 341 is located on the side of the mounting sleeve 311 away from the axis of the sealing tank 2. Therefore, the vibrating rod 32 will not contact the cam 341 when it rotates with the rotating ring 31. The balls 344 on the periphery of the cam 341 protrude from the periphery of the cam 341. Therefore, when contacting the bottom of the connecting ring 325, the sliding friction can be converted into rolling friction, thereby making the rotating ring 31 and the vibrating rod 32 rotate smoothly and reducing the influence of the heat generated by the friction between the connecting ring 325 and the cam 341 on the raw materials.

[0032] In order to prevent the raw materials falling from the feed pipe 21 from directly contacting the rotating ring 31 and the connecting ring 325, the following features are specifically provided: A shielding cover 252 is provided on the annular mounting frame 25 , and the rotating ring 31 and the connecting ring 325 are located and move inside the shielding cover 252 .

[0033] A shielding cover 252 is provided on the annular mounting frame 25 in this embodiment, and the rotating ring 31 and the connecting ring 325 are both located inside the shielding cover 252. Therefore, the raw materials dropped from the feeding pipe 21 can be prevented from contacting with the rotating ring 31 and the connecting ring 325. A certain curvature can be set on the top of the shielding cover 252 to ensure that the raw materials are completely mixed in the sealed tank 2.

[0034] In order to prevent the raw materials at the bottom of the sealed tank 2 from directly entering the working end of the screw extruder 22 through the connecting pipe 23 without being mixed and vibrated to exhaust, the following features are specifically set: A hopper 26 is coaxially arranged inside the sealed tank 2, and the hopper 26 is located below the annular mounting frame 25. The outer wall of the hopper 26 fits the inner wall of the sealed tank 2, and the opening of the hopper 26 is arranged upward; the bottom of the hopper 26 is provided with a taper that gradually decreases downward, and a discharge pipe 261 is provided at the bottom of the hopper 26, and the discharge pipe 261 is inserted in the connecting pipe 23; the hopper 26 moves along the axis of the sealed tank 2, and the sealed tank 2 is located in the hopper 26 and coaxially provided with a blocking block 27, the diameter of the blocking block 27 is larger than the diameter of the discharge pipe 261, and the bottom of the blocking block 27 has the same conical surface as that of the hopper 26, and when the hopper 26 moves up until the blocking block 27 fits the inner wall of the hopper 26, the blocking block 27 blocks the discharge pipe 261.

[0035] In this embodiment, a hopper 26 is provided in the sealed tank 2, and the raw materials dropped through the feed pipe 21 fall into the hopper 26, and the discharge pipe 261 at the bottom of the hopper 26 is inserted in the connecting pipe 23, so that the raw materials in the hopper 26 can be transported to the screw extruder 22. When the raw materials enter the sealed tank 2, the hopper 26 is in a high position and its inner wall is in contact with the blocking block 27 in the sealed tank 2, and the blocking block 27 blocks the upper opening of the discharge pipe 261, thereby retaining the raw materials in the hopper 26, and the rotating ring 31 drives the vibrating rod 32 to stir the raw materials in the hopper 26, and then the vibrating rod 32 stirs the raw materials in the hopper 26 alone. Vibration is performed to exhaust. When the exhaust is completed, the hopper 26 moves downward in the sealed tank 2, so that the blocking block 27 is separated from the top opening of the discharge pipe 261. The raw materials in the sealed tank 2 enter the working end of the screw extruder 22 through the discharge pipe 261. The screw extruder 22 conveys the exhausted raw materials. The existence of the hopper 26 and the blocking block 27 ensures that the raw materials entering the screw extruder 22 are completely mixed and exhausted, and the screw extruder 22 can start and stop in coordination with the movement of the hopper 26. When the hopper 26 is at a high position, the screw extruder 22 stops conveying, and the raw materials can be filled in the screw extruder 22 through intermittent feeding. In this embodiment, the diameter of the blocking block 27 is larger than the diameter of the discharge pipe 261, ensuring that the discharge pipe 261 can be completely blocked when the blocking block 27 fits the inner wall of the hopper 26.

[0036] In order to solve the problem of how to fix the position of the blocking block 27 in the sealing tank 2, the following features are specifically set: At least two mounting rods 271 extending vertically upward are provided on the top of the blocking block 27 , and the mounting rods 271 are fixedly connected to the air box 24 .

[0037] The blocking block 27 in this embodiment is fixedly connected to the air box 24 above the sealing tank 2 via the top mounting rod 271, thereby releasing the space below the blocking block 27 and ensuring that the bottom surface of the blocking block 27 fits against the inner wall of the hopper 26. The mounting rod 271 can be positioned in the middle of the vibrating rod 32 to avoid affecting the rotation of the vibrating rod 32.

[0038] In order to solve the problem of how to drive the hopper 26 to move in the vertical direction, the following features are specifically set: The outer wall of the hopper 26 is provided with a plurality of guide rods 262 extending vertically downward. The guide rods 262 are inserted into the sealed tank 2 and extend to the outside of the sealed tank 2. All the guide rods 262 are connected to the moving plate 263. The frame 1 is provided with a linear drive 264 for driving the moving plate 263 to move in the vertical direction.

[0039] A guide rod 262 extending vertically downward is provided on the outer wall of the hopper 26 in this embodiment. The hopper 26 is inserted into the sealed tank 2 through the guide rod 262 and extends to the outside of the sealed tank 2. The existence of the guide rod 262 stabilizes the moving path of the hopper 26 in the vertical direction. The guide rod 262 is connected to the movable plate 263 located outside the sealed tank 2. The linear drive 264 is fixedly installed on the frame 1 to keep the working end moving in the vertical direction. The linear drive 264 is connected to the movable plate 263 to push the hopper 26 to rise and fall inside the sealed tank 2 from the outside of the sealed tank 2, thereby realizing the blocking and release of the discharge pipe 261. The linear drive 264 in this embodiment can be a cylinder, an oil cylinder or an electric push rod, etc.

[0040] The ABS material preparation method is applied to ABS material production equipment, comprising the following steps: Step 1: All raw materials are introduced into the feed pipe 21 of the sealed tank 2 through the conveying device and enter the sealed tank 2; Step 2: The first driving unit 33 of the stirring unit 3 drives the rotating ring 31 to drive the vibrating rod 32 to rotate, so as to stir and mix the materials in the sealed tank 2; Step 3: The first driving unit 33 stops moving, and the second driving unit 34 drives the vibrating rod 32 to vibrate and vibrate the material in the sealed tank 2 to discharge the gas in the material. The gas in the sealed tank 2 is discharged from the inside of the sealed tank 2 through the gas outlet pipe 242 of the gas box 24; Step 4: The vibrated material enters the screw extruder 22 through the connecting pipe 23 at the bottom of the sealed tank 2, and the screw extruder 22 extrude and shape the material.

[0041] Working principle: When in use, the multiple feed pipes 21 on the sealed tank 2 are respectively connected to the output ends of the conveying devices of different raw materials, so that the raw materials can directly enter the sealed tank 2 through the feed pipes 21 and be directly conveyed to the bottom of the air box 24. The linear drive 264 drives the hopper 26 in the sealed tank 2 to move upward, and the blocking block 27 fits the upper opening of the discharge pipe 261 and blocks the discharge pipe 261. The raw materials are located in the hopper 26.
