The rotating nip roll 301 can prevent the flour dough from blocking the material passing groove 303 in the process of entering the side of the perforated screen 201 from the side of the solid screen 202.

As a preferred embodiment: the upper surface of the solid screen 202 is obliquely arranged, the inclination angle is 3-5 degrees, and the upper surface of the solid screen 202 is made of smooth stainless steel. On one hand, the flour can be prevented from being adhered to the surface of the smooth stainless steel; on the other hand, during the reciprocating swing of the material sieve 201, the flour dough is promoted to slowly enter the side of the perforated sieve 201 from the side of the solid sieve 202.

Wherein, scraping mechanism 4 is used for stirring getting into hourglass hole sieve 203 one side and slightly hammering the tiny flour dough after mechanism 5 hammers into shape through hammering to avoid hammering the powder dough bonding in-process of expecting to block up the sieve mesh through the scraping to hourglass hole sieve 203 surface. Specifically, the method comprises the following steps:

the scraping mechanism 4 comprises a limiting guide rail 401 arranged parallel to the nip roll 301, and a slide rod 402 slidably mounted on the limiting guide rail 401, wherein a first toggle block 403 capable of being matched with the annular guide groove 302 is arranged on the side wall of the slide rod 402, and the first toggle block 403 can be ensured to reciprocate along the annular guide groove 302 in the same horizontal direction in the unidirectional rotation process of the nip roll 301.

The slide bar 402 is also connected to a flipping bar 404 by a connecting bar 414. The turnover rod 404 can rotate relative to the connecting rod 414, the inner end of the turnover rod 404 is connected with the nip roll 301 through a power assembly, and the outer end of the turnover rod 404 is connected with a scraper 405 which can be in mutual contact with the surface of the perforated screen 201;

the power component comprises a dial 406 arranged at the side end of the nip roll 301, two constant-radius guide arc-shaped grooves 407 which are concentric with the roll shaft of the nip roll 301 but have different radiuses and two reducing arc-shaped grooves 408 connecting the adjacent ends of the two constant-radius guide arc-shaped grooves 407 are oppositely arranged on the dial 406, a guide cylinder 409 is rotatably arranged at one side parallel to the limiting guide rail 401, the inner end of the guide cylinder 409 is connected with a rotating rod 410, the far end of the rotating rod 410 is connected with a third toggle block 411 which is matched with the constant-radius guide arc-shaped groove 407 and the reducing arc-shaped groove 408, the turning rod 404 is movably sleeved in the guide cylinder 409, the inner cylinder wall of the guide cylinder 409 is provided with a turning rod limiting groove 412 along the direction of the extension of the axis thereof, the side wall of the turning rod 404 is provided with a turning rod positioning edge 413 which can slide along the turning rod limiting groove 412.

Wherein, the material hammering mechanism 5 is used for lightly hammering the fine flour dough entering one side of the perforated sieve 203, which is beneficial to improving the sieving rate of the flour. Specifically, the method comprises the following steps:

the hammering mechanism 5 comprises a vertical guide rail 501, a hammering plate 502 slidably mounted on the vertical guide rail 501, a second toggle block 504 connected to the slide rod 402, and a linear guide groove 503 obliquely arranged on the surface of the hammering plate 502, wherein the second toggle block 504 is matched with the linear guide groove 503.

The hammer plate 502 includes a lifting plate 506 capable of sliding along the vertical guide rail 501 and a hammer plate 507 mounted at the lower end of the lifting plate 506, and the linear guide groove 503 is disposed on the plate surface of the lifting plate 506.

The scraper 405 is asymmetrically arranged at the tail end of the axial line of the turnover rod 404, the scraper 405 can contact the upper surface of the perforated screen 201 when horizontally arranged, and the lower end of the scraper 405 can press down the upper surface of the perforated screen 201 when the scraper 405 is rotatably arranged relative to the horizontal plane. The asymmetrical arrangement mode can ensure that the scraper 405 has a larger scraping surface when in a horizontal state; on the other hand, the length of the lower end of the scraper 405 in the rotating process is not too long, so that the sieve surface 207 of the perforated sieve 201 pressed by the scraper is greatly fluctuated and exceeds the elastic limit of the sieve surface 207.

The power mechanism 202 comprises a driving roller 205 and a driven roller 206 which are positioned below the material sieve 201 and connected through a belt pulley mechanism 210, the belt pulley mechanism 210 is driven to rotate through a second motor 211, and the perforated sieve 203 and the solid sieve 204 both comprise a sieve surface 207 and striker plates 208 arranged on two sides of the sieve surface 207.

In order to improve the stability of the horizontal movement of the turnover rod 404, the side wall of the striker plate 208 is provided with a guide hole 213 for penetrating through the turnover rod 404.

The driving roller 205 and the driven roller 206 both act on the lower surface of the screen surface 207, the upper ends of the two striker plates 208 of the solid screen 204 are further provided with driven pressing rollers 209, and the plane of the lower end of the nip roller 301 is lower than the upper surface of the striker plate 208.

The working principle of the device is as follows:

the flour with the wet worm is poured above the solid sieve 204 of the grading sieving mechanism 2 from the feeding hole 102 of the box body 101, and the baffle plates 208 on the two sides of the solid sieve 204 prevent flour dough from falling off from the two sides;

then, the second motor 211 and the first motor are started simultaneously, the second motor 211 drives the driving roller 205 and the driven roller 206 which are connected by the belt wheel mechanism 210 to synchronously rotate, and the upper surface and the lower surface of the solid screen 204 are respectively clamped by the driving roller 205 and the driven pressing roller 209, so that the clamped material screen 201 shakes left and right in the process of forward and reverse rotation of the second motor 211.

The drying mechanism dries flour dough above the solid screen 204 at low temperature, part of the fine flour dough can enter the perforated screen 203 at the other side of the nip roller 301 through the material passing groove 303 below the nip roller 301 in the shaking process for subsequent treatment, and larger flour dough is continuously dried on one side of the solid screen 204 in a shaking way.

Because the nip roll 301 is driven to rotate by the first motor, the flour dough passing through the lower part of the material passing groove 303 can be rolled, and the flour dough is prevented from being accumulated in the material passing groove 303.

In the process of rotating the nip roll 301, the slide bar 402 where the first toggle block 403 limited by the annular guide groove 302 on the surface of the nip roll 301 is located reciprocates left and right due to the limiting and guiding function of the limiting and guiding rail 401.

In the embodiment of the invention, when the sliding rod 402 moves to the right, the second toggle block 504 connected to the sliding rod 402 also moves to the right, the second toggle block 504 can make the lifting plate 506 limited by the second toggle block through the linear guide groove 503 descend along the vertical guide rail 501, the hammer plate 507 at the lower end of the lifting plate 506 descends, and the flour dough on the surface of the perforated screen 201 is lightly hammered.

At the same time, as shown in fig. 2 and 5: when the slide bar 402 moves to the right, the flipping bar 404 connected to the slide bar 402 by the connecting bar 414 also moves to the right.

At this time, the third toggle block 411 connected to the guide cylinder 409 through the rotating rod 410 is inserted into the constant radius guide arc groove 407 in the side wall of the dial 406 on one side of the nip roll 301, and because the radius of the constant radius guide arc groove 407 is constant, in the process that the dial 406 rotates along with the nip roll 301, the third toggle block 411 inserted into the constant radius guide arc groove 407 does not rotate, that is, the turning rod 404 limited by the guide cylinder 409 does not rotate, when the turning rod 404 moves towards the right side, the scraper 405 connected to the end thereof is in a horizontal state, and in the process that the scraper 405 slides along the sieve surface 207 of the perforated sieve 203 from left to right, the flour adhered to the sieve aperture near the sieve surface 207 is scraped off, so that the flour is prevented from blocking the sieve aperture of the sieve surface 207. This process also stirs the flour that was previously lightly hammered by the hammer plate 507, increasing its looseness.

It should be noted that: when the hammer 507 drops to the surface of the screening surface 207, the scraper 405 just completes one scraping of the screening surface 207.

When the sliding rod 402 moves to the left, the second moving block 504 connected to the sliding rod 402 also moves to the left, and the second moving block 504 can make the lifting plate 506 limited by the second moving block through the linear guide groove 503 move upward along the vertical guide rail 501.

At the same time, as shown in fig. 3 and 6: when the slide bar 402 moves toward the left side, the flipping bar 404 connected to the slide bar 402 by the connection bar 414 also moves toward the left side.

At this time, the third toggle block 411 connected to the guide sleeve 409 via the rotating rod 410 is inserted into the reducing arc-shaped groove 408 on the side wall of the dial 406 on one side of the nip roller 301, since the radius of the reducing arc-shaped groove 408 is constantly changed, the third dial block 411 inserted therein is rotated by a certain extent along with the rotation of the dial 406, the guide cylinder 409 connected to the third dial block 411 by the rotation lever 410 is also rotated, because the guide cylinder 409 is connected with the turning rod 404 in a limiting way through the turning rod limiting groove 412 and the turning rod positioning edge 413, therefore, when the guide cylinder 409 rotates, the turning rod 404 nested inside the guide cylinder rotates along with the guide cylinder, that is, when the weight plate 507 is raised, the blade 405 rotates from the horizontal position to the vertical position, and the rotation is accompanied by the horizontal movement from the right to the left, and when the tilt lever 404 rotates, the lower end of the side of the scraper 405 connected thereto will gradually bulge downwards from a horizontal position against the screening surface 207. The screen surface 207 is pressed down, and the screen surface 207 plays a shaking effect in the fluctuating process, so that the flour above the perforated screen 203 can be more favorably screened to the discharge hole 103 of the box body 101.

According to the invention, the wet flour is classified by the classifying and screening mechanism 2, and the flour with large and small lumps is respectively placed on the solid screen 204 for drying and further screened on the perforated screen 203 by the left-right shaking material screen 201, so that compared with the previous mixing and screening, the processing efficiency of the wet flour is favorably accelerated, and the wet large flour lumps are prevented from being further adhered to the finely-crushed flour;

the flour dough falling into the sieve face 207 of the sieve with the leakage holes is further lightly hammered, stirred and shaken to be processed by the aid of the material blocking mechanism 3, the material scraping mechanism 4 and the material hammering mechanism 5 in cooperation, when the pressure roller 301 of the material blocking mechanism 3 rotates, fine flour dough is synchronously piled, flour adhered to the sieve face 207 of the sieve with the leakage holes is scraped, and the flour is prevented from blocking sieve holes.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
