Description

A multi-stage screening bed for pre-feeding of gluten-free food

Technical Field

The invention relates to the technical field of sorting equipment, in particular to a multi-stage screening bed for pre-materials used in gluten-free food processing.

Background technique

The pre-feed multi-stage screening bed is a kind of equipment used in food processing, which is usually used to remove impurities, foreign matter and particles that do not meet the specifications in food raw materials. In the processing of gluten-free foods, the pre-feed multi-stage screening bed is particularly important because of the need to ensure the purity and quality of the food;

In the prior art, when placing food raw materials into the sieving bed manually, due to the busy work in the factory, the food raw materials may be piled up at a certain place of the sieving bed due to manual placement, which may cause the food raw materials to hinder the normal operation of the screen, resulting in a decrease in screening efficiency, thereby failing to effectively remove impurities or foreign matter, affecting the quality of the final product. At the same time, the accumulated food raw materials will reduce the effective screening area of the sieving bed, thereby reducing the output. If the accumulation on the sieving bed is serious, it may even cause the equipment to stop working, further affecting the production efficiency.

In addition, when the screened food raw materials contain dust or impurities that can float in the air, if the dust is not reduced in time, the dust generated during the screening process will spread into the air of the production workshop, affecting the hygiene and cleanliness of the production environment. The presence of a large amount of dust will not only affect the work efficiency and health of the production personnel, but may also affect the hygiene standards of the entire production line. Secondly, the presence of water mist will make the surface of the food raw materials moist, causing adhesion between the food raw materials, affecting the screening effect, thereby making the screening process difficult, reducing the screening efficiency, and even causing the screening equipment to be blocked.

In view of this, the present invention proposes a multi-stage screening bed for pre-processing gluten-free food to make up for and improve the deficiencies of the prior art.

Further examples:

As shown in FIGS. 8 to 10 , the intermittent dust reduction mechanism 3 includes a rotating plate 301, the rotating plate 301 is rotatably connected to the side wall of the bottom of the inner cavity of the protection box body 1 with a discharge port, a telescopic column 303 is hinged on the upper surface of the rotating plate 301, and a connecting plate 302 is provided at one end of the telescopic column 303 away from the rotating plate 301, the telescopic column 303 is hinged to the side wall of the connecting plate 302, and the bottom of the connecting plate 302 is fixedly connected to the bottom of the inner cavity of the protection box body 1;

The bottom of the rotating plate 301 is fixedly connected to a base 304, the middle of the base 304 is rotatably connected to a reciprocating push rod 305, one end of the reciprocating push rod 305 away from the base 304 is hinged to a telescopic rod 306, the outer surface of the telescopic rod 306 is provided with a telescopic cylinder 307, the telescopic rod 306 is slidably connected to the inside of the telescopic cylinder 307, the outer surface of the telescopic cylinder 307 is fixedly connected to a water storage fixed block 308, and the water storage fixed block 308 is fixedly connected to the bottom of the protection box 1;

Among them: a water inlet pipe is arranged between the telescopic cylinder 307 and the water storage fixed block 308, and a one-way valve is arranged between the telescopic cylinder 307 and the water inlet pipe, two groups of rotating plates 301 are symmetrically distributed about the central axis of the protection box body 1, and are rotatably connected to the side wall of the discharge port opened at the bottom of the inner cavity of the protection box body 1 through a rotating shaft, the telescopic column 303 includes a telescopic sleeve, and a telescopic spring is fixedly connected to the top of the inner cavity of the telescopic sleeve, and a telescopic connecting rod is fixedly connected to the end of the telescopic spring away from the top of the inner cavity of the telescopic sleeve, and the telescopic connecting rod is slidably connected to the inner cavity opened inside the telescopic sleeve.

The effects achieved by this embodiment are as follows: In the prior art, when the screened food raw materials contain dust or impurities that can float in the air, if dust reduction is not timely, the dust generated during the screening process will spread into the air of the production workshop, affecting the hygiene and cleanliness of the production environment. The presence of a large amount of dust will not only affect the work efficiency and health of the production personnel, but may also affect the hygiene standards of the entire production line. Secondly, the presence of water mist will make the surface of the food raw materials moist, causing adhesion between the food raw materials, affecting the screening effect, thereby making the screening process difficult, reducing the screening efficiency, and even causing the screening equipment to be blocked. Compared with the prior art, through the cooperation of the reciprocating push rod 305 and the telescopic rod 306 in the intermittent dust reduction mechanism 3, a small amount of water can be sprayed on the raw materials when they fall into the collection box 4. Mist can effectively reduce the dust content of food raw materials, reduce the dust concentration in the air, keep the production environment clean, improve the working environment and production safety of the staff, and at the same time, by spraying water mist, the food raw materials can maintain a certain humidity, which is beneficial for some fragile raw materials to be less likely to generate dust and debris in the subsequent processing process, thereby improving the quality of the product. Secondly, through the cooperation of the connecting plate 302 and the telescopic column 303 in the intermittent dust reduction mechanism 3, the rotating plate 301 can be closed again when the food raw materials fall into the collection box 4, thereby reducing the water vapor entering the screening area to a certain extent, thereby keeping the food raw materials dry and improving the screening efficiency. Since wet raw materials often stick to the screen, affecting the screening effect, dry raw materials are more easily screened and separated.

The complete usage steps and working principle of the above embodiment are as follows:

In the initial state: the output motor 210 in the vibration smoothing mechanism 2 is not turned on, the push column 206 is located near the guide block 205, no food raw materials are placed on the filter frame 204, the two sets of rotating plates 301 in the intermittent dust reduction mechanism 3 are in a closed state, the spring in the telescopic column 303 and the rotating plate 301 are in a balanced state, the telescopic rod 306 is located near the base 304, the telescopic cylinder 307 is filled with water, and the output shaft 208 is fixedly connected to the output end of the external drive motor;

The following is the working process of the vibration smoothing mechanism 2:

Furthermore, the staff puts the food raw materials into the side of the filter frame 204 close to the guide block 205 through the feed port opened on the protective box body 1. At this time, the output shaft 208 fixedly connected thereto is driven to rotate by starting the external motor. Since the outer ring surface of the output shaft 208 is provided with an annular guide groove, when the motor is started, the output shaft 208 and the guide groove opened on the outer ring surface are driven to rotate. Moreover, since the sliding guide ball 207 fixedly connected to the inner wall of the push column 206 slides in the slide groove opened on the outer surface of the output shaft 208, when the output shaft 208 rotates, the push column 206 is driven to reciprocate along the annular slide groove opened in the middle part of the guide block 205, and further, the oblique push plate 209 fixedly connected to the push column 206 is driven to reciprocate. At this time, the food raw materials accumulated on the filter frame 204 can be scattered, and at the same time, the food raw materials are pushed into the area of the filter frame 204 containing the screening port;

At this time, the output motor 210 is started. When the output motor 210 is turned on, it will drive the rotating shaft 211 fixedly connected to it to rotate, and further drive the rotating disk 212 fixedly connected to its end face to rotate. Since the fixed shaft 213 is fixedly connected to the outer ring surface of the rotating disk 212 away from the rotating shaft 211, when the rotating disk 212 rotates, it will drive the fixed shaft 213 to rotate synchronously, and further drive the reciprocating connecting rod 214 rotatably connected to one end of the fixed shaft 213 to reciprocate. The end of the reciprocating connecting rod 214 away from the fixed shaft 213 is fixedly connected to the side of the filter frame 215, and the filter frame 1 204 and the filter frame 215 are inclined in opposite directions, and the inclined ends are respectively placed above the collection box 2 5 and the collection box 3 6 fixedly connected to the inner cavity of the protection box 1, so when the impurities on the filter frame 1 204 and the filter frame 215 that have not passed the screening area will fall into the collection box 3 6 of the collection box 2 5, at the same time, due to the cooperation of the rotating disc 212, the fixed shaft 213 and the reciprocating connecting rod 214, it can drive The filter frame 215 makes reciprocating motion, but since the filter frame 215 is fixedly connected to the filter frame 1 204 through the elastic rectangular plate 217 and since the elastic rectangular plate 217 is made of elastic material, when the output motor 210 is started, the filter frame 215 will be driven to make a small range of reciprocating motion, and since the rotating disc 212 and the elastic rectangular plate 1 202 are made of elastic material, and the elastic rectangular plate 1 202 is fixedly connected to the inner cavity side wall of the protection box body 1 through the fixing block 1 201, when the output motor 210 is started, it will also drive the filter frame 215 to make a small range of reciprocating motion. The movable filter frame 1 204 and the filter frame 2 215 make a small range of reciprocating motion, so that the food raw materials on the upper surface can be screened. At this time, the food raw materials screened by the filter frame 2 215 will fall to the bottom of the inner cavity of the protection box 1, which can make the raw materials evenly distributed, reduce the accumulation and intersection between the raw materials, and help the screening equipment to evenly screen the raw materials and improve the screening efficiency. At the same time, pushing the raw materials can ensure that the materials are more evenly distributed on the screen surface, thereby achieving uniform screening and improving product quality.

Please refer to Figures 1 to 7 for the above working process.

The following is the working process of the intermittent dust reduction mechanism 3:

Furthermore, since it is known that the food raw materials screened by the vibration smoothing mechanism 2 will fall to the lower surface of the inner cavity of the protection box body 1, and since the lower surface of the inner cavity of the protection box body 1 is a curved surface structure, the food raw materials that fall to the upper surface of the inner cavity of the protection box body 1 will gradually gather on the upper surfaces of the two sets of rotating plates 301. At the same time, the reciprocating motion of the vibration smoothing mechanism 2 will generate a small amount of vibration, which will accelerate the speed of the food raw materials gathering to the middle. When the weight of the food raw materials accumulated on the upper surface of the rotating plate 301 exceeds the load-bearing capacity of the spring inside the telescopic column 303, the rod at the bottom of the telescopic column 303 will rotate At the same time, since the rotating plate 301 is rotatably connected to the bottom of the inner cavity of the protection box body 1, the rotating plate 301 will rotate downward through the rotating shaft of the rotating plate 301 and the bottom of the inner cavity of the protection box body 1. At the same time, since the connecting plate 302 and the rotating plate 301 are both hinged to the telescopic column 303, the rotating plate 301 will not affect the telescopic column 303 when it rotates. At the same time, when the rotating plate 301 rotates around its rotating shaft, it will squeeze the hinged reciprocating driving rod 305 through the base 304, further driving the telescopic rod 306 hinged to the reciprocating driving rod 305 When the food raw materials on the rotating plate 301 fall into the collecting box 4, the spring inside the telescopic column 303 will reset, so it will pull the rotating plate 301 to rotate around its axis, thereby returning to the initial state, and further preventing the water mist of the telescopic cylinder 307 from entering the interior of the device through the discharge port at the bottom of the protection box 1, which can not only effectively reduce the dust content of the food raw materials, but also reduce the dust concentration in the air. Keep the production environment clean, improve the working environment and production safety of the staff, and at the same time, by spraying water mist, the food raw materials can maintain a certain humidity, which is conducive to some fragile raw materials not easily generating dust and debris in the subsequent processing process, thereby improving the quality of the product. The cooperation of the connecting plate 302 and the telescopic column 303 can also reduce the entry of water vapor into the screening area to a certain extent, thereby keeping the food raw materials dry and improving the screening efficiency. Since wet raw materials often stick to the screen, affecting the screening effect, dry raw materials are easier to be screened and separated;

Please refer to Figures 8 to 10 for the above working process.

Summary: Through the cooperation of the pushing column 206 and the inclined pushing plate 209 in the vibration smoothing mechanism 2, the food raw materials can be pushed apart when they enter the filter frame 204. At the same time, the accumulated food raw materials can be pushed to the area with sieve holes on the filter frame 204, so that the raw materials can be evenly distributed and the accumulation between the raw materials can be reduced, which is conducive to the screening equipment to evenly screen the raw materials and improve the screening efficiency. In addition, through the cooperation of the reciprocating pushing rod 305 and the telescopic rod 306 in the intermittent dust reduction mechanism 3, a small amount of water mist can be sprayed on the raw materials when they fall into the collection box 4, thereby effectively reducing the dust content of the food raw materials, reducing the dust concentration in the air, keeping the production environment clean, and improving the working environment and production safety of the staff. At the same time, through the cooperation of the connecting plate 302 and the telescopic column 303 in the intermittent dust reduction mechanism 3, the rotating plate 301 can be closed again when the food raw materials fall into the collection box 4, thereby reducing the water vapor entering the screening area to a certain extent, thereby keeping the food raw materials in a dry state and improving the screening efficiency.
