Description

Technical Field

[0001] The utility model relates to the technical field of material conveying equipment, in particular to an air extraction type material leveling device. Background Technique

[0002] An air extraction type material leveling device is a device that realizes uniform distribution of materials through air extraction during the material processing process. This device is usually applied to occasions that require precise control of material flow and distribution, such as the processing of powder and granular materials in industries such as chemical industry, pharmaceutical industry, and food industry. The air extraction type material leveling device mainly sets an air extraction system inside the device, and uses the action of negative pressure or air flow to suck materials from one place or multiple points, and mixes, disperses, and evenly distributes them inside the device.

[0003] Generally, in an air extraction type material leveling device, the air flow generated by the air extraction system can penetrate the material layer, causing relative movement between material particles, thereby realizing material homogenization. When the suction pipe sucks the material into the device for mixing, it is easy to accumulate the material at the feeding port, affecting the material leveling speed of the device. For this reason, we have designed an air extraction type material leveling device to solve the above problems. Content of the Utility Model

[0012] Advantages of the present utility model:

[0013] In the present utility model, through the cooperation of parts such as the reciprocating lead screw, the reciprocating lead screw is driven to rotate, and then the first material pushing plate is driven to move towards the fixed plate direction, so as to spread the materials piled up in one place, thereby preventing the materials from piling up in one place and affecting the material leveling effect.

The output end of the driving motor 201 penetrates to the inside of the vibrating screen 1 and is fixedly connected with a reciprocating lead screw 202, and the reciprocating lead screw 202 is rotationally connected with the vibrating screen 1. A limiting column 204 is fixedly connected inside the vibrating screen 1. The outer wall of the limiting column 204 is slidably connected with a first material pushing plate 203, and the first material pushing plate 203 is threadedly connected with the reciprocating lead screw 202. A fixing plate 205 is fixedly connected inside the vibrating screen 1, and the fixing plate 205 is fixedly connected with the limiting column 204. The fixing plate 205 is rotationally connected with the reciprocating lead screw 202; a rotating material pushing mechanism 3 is arranged inside the vibrating screen 1 for assisting the material pushing mechanism 2 to push the material; an auxiliary material pushing mechanism 4 is arranged inside the vibrating screen 1 for pushing the material in the corner to prevent material accumulation in the corner;

[0024] In this embodiment: When the staff starts the air extraction type material leveling device, a blower can be installed at the end of the feed pipe 6. A material guiding pipe for feeding is provided on the outer wall of the feed pipe 6. When the material in powder state or granular state enters the inside of the feed pipe 6 through the material guiding pipe, it can be blown into the material guiding hopper 5 by the blower and conveyed to the vibrating screen 1 through the discharge pipe 7 for screening. When the material falls onto the vibrating screen 1, start the driving motor 201. The output end of the driving motor 201 drives the reciprocating lead screw 202 to rotate, and then drives the first material pushing plate 203 to move towards the fixing plate 205, so as to spread the material piled up in one place, thereby avoiding the influence of material accumulation in one place on the material leveling effect. After pushing the material to the discharge outlet, the reciprocating lead screw 202 continues to rotate, thereby driving the first material pushing plate 203 back to the initial position, realizing the reciprocating pushing of the material, thereby increasing the material leveling efficiency of the device and improving the overall practicality of the device.

[0025] Please refer to Figures 2-5, the rotating material pushing mechanism 3 includes two limit seats 305 fixedly connected to both sides of the reciprocating lead screw 202. A rotating rod 307 is rotatably connected between the two limit seats 305. A second material pushing plate 303 is fixedly connected to the outer wall of the rotating rod 307. The rotating material pushing mechanism 3 further includes a driving plate 301 fixedly connected to the top of the limit post 204. A spur gear 306 is fixedly connected to the outer wall of the rotating rod 307. A limit chute 309 is provided at the top of the first material pushing plate 203. A limit plate 308 is slidably connected to the inside of the limit chute 309. A spur rack 302 is fixedly connected to the top of the limit plate 308, and the spur rack 302 meshes with the spur gear 306. One end of the spur rack 302 is fixedly connected to a spherical rod 304. A connecting block 310 is fixedly connected to the top of the first material pushing plate 203. A return spring 311 is installed between the limit plate 308 and the connecting block 310. One end of the spherical rod 304 is provided with a spherical surface. A plurality of arched ramps are provided inside the driving plate 301, and the plurality of arched ramps are equidistantly distributed inside the driving plate 301;

[0026] In this embodiment: When the first material pushing plate 203 moves towards the fixed plate 205, the limit plate 308 moves under the action of the first material pushing plate 203, thereby driving the spherical rod 304 to move. When the spherical rod 304 moves from the lowest end of the arched ramp to the highest point, the arched ramp pushes the spherical rod 304 to gradually move towards the side of the spur gear 306, thereby driving the spur rack 302 to move, and then driving the spur gear 306 to rotate, thereby driving the second material pushing plate 303 to rotate. The material is pushed towards the side of the vibrating screen 1 by the rotation of the second material pushing plate 303. When the spherical rod 304 moves from the top of the arched ramp to its bottom, the spur rack 302 is pushed back towards the driving plate 301 under the action of the return spring 311, thereby realizing the reciprocating movement of the spur rack 302, and then realizing the reciprocating swing of the second material pushing plate 303, thus realizing the reciprocating pushing of the material to both sides, so that the material can be evenly dispersed to avoid accumulation, and further improving the subsequent material leveling effect, thereby further improving the overall practicality of the device.

[0027] Please refer to Figure 3 and Figure 4 , the auxiliary material pushing mechanism 4 includes an inclined rod 406 fixedly connected to the inside of the vibrating screen 1. A third material pushing plate 407 is slidably connected to the outside of the inclined rod 406. One end of the inclined rod 406 is fixedly connected to a rectangular plate 409. A second tension spring 408 is installed between the third material pushing plate 407 and the rectangular plate 409. The auxiliary material pushing mechanism 4 further includes a fixed strip 405 fixedly connected to one side of the first material pushing plate 203. A sliding block 404 is fixedly connected to one side of the fixed strip 405. A sliding rod 402 is slidably connected to the inside of the sliding block 404. An inclined plate 401 is fixedly connected to the bottom of the sliding rod 402. A first tension spring 403 is installed between the inclined plate 401 and the sliding block 404.

[0028] In this embodiment: while the first pushing plate 203 moves towards the fixed plate 205, the fixing bar 405 is driven to move under the action of the first pushing plate 203, thereby driving the inclined plate 401 to move. Under the action of the inclined plate 401, the third pushing plate 407 moves towards the fixed plate 205, so as to push the materials at the inner corner of the vibrating screen 1, thereby realizing the pushing of the materials in the corner, preventing the materials from accumulating in the corner, and improving the overall practicability of the device;

[0029] When the third pushing plate 407 moves towards the discharge port, it will continue to move along the inclined rod 406, so that the third pushing plate 407 gradually moves downward during the movement. When the top of the third pushing plate 407 moves down to the bottom of the inclined plate 401, at this time, the inclined plate 401 is separated from the third pushing plate 407. Subsequently, the third pushing plate 407 is reset under the action of the second tension spring 408. When the first pushing plate 203 is reset and the inclined plate 401 contacts the third pushing plate 407, under the action of the third pushing plate 407, the inclined plate 401 is driven to move upward. When the inclined plate 401 moves to the maximum position, at this time, the inclined plate 401 moves to one side of the third pushing plate 407. Thus, under the action of the first tension spring 403, the inclined plate 401 moves downward, so that the inclined plate 401 returns to the initial position, thereby realizing the reciprocating movement of the third pushing plate 407, further improving the pushing effect of the device, and thus improving the overall practicability of the device.
