Description

Technical Field

[0001] This utility model belongs to the field of auxiliary devices for candy tablet presses, and relates to a dust collection device for candy tablet presses. Background Technology

[0002] Compressed candy refers to a type of snack where powder is directly compressed into tablets without granulation. When using a tablet press to shape the candy, a large amount of dust is generated during the pressing process. Therefore, most production workshops use dust extraction devices to remove dust from the tablet press during production to prevent dust pollution and ensure the quality of the candy. Most existing candy tablet presses use a transparent cover to seal the entire machine, preventing external dust from entering and contaminating the candy, and also preventing candy powder generated during production from leaking out. However, when switching between different flavors of compressed candy, it is necessary to remove candy powder from around the tablet press to prevent flavor mixing. The transparent cover seal makes it difficult to remove candy powder from inside the machine.

[0003] Therefore, this utility model provides a dust extraction device for a candy tablet press, which solves the above problems. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a dust collection device for a candy tablet press. The technical solution adopted is as follows: The candy tablet press body includes a base. A tablet pressing assembly is set at the upper center of the base. A top plate is fixedly fitted to the top of the tablet pressing assembly. The four corners of the top plate are fixedly connected to the four corners of the base by reinforcing rods. A downwardly inclined baffle is fixedly installed on the outer right edge of the upper part of the base. A trapezoidal dust collection cover is sealed on the upper part of the baffle. Transparent plates are installed between the remaining adjacent reinforcing rods. A dust blowing mechanism is inserted into the upper left corner of the front and rear transparent plates. The dust blowing mechanism includes a bidirectional lead screw inserted into the front and rear transparent plates. A guide post is fixedly installed between the front and rear plate walls on the right side of the bidirectional lead screw. U-shaped moving blocks are movably fitted on the front and rear sides of the bidirectional lead screw and guide post. The left side wall and the lower middle part of the U-shaped moving block are also included. An L-shaped notch is created, with holes on the front and rear sides of the horizontal section of the L-shaped notch for rotating insert shafts. A fixing ring is provided in the middle of the shaft, and gears are fixed on the shafts on opposite sides of the fixing rings. The left edge of the gear passes through the L-shaped notch and meshes with the teeth of a rack movably mounted on the left outer wall of the U-shaped moving block. The upper end of the rack is fixedly connected to the telescopic shaft of a miniature electric push rod mounted on the upper left outer wall of the U-shaped moving block. A V-shaped air nozzle is fixedly mounted inside the fixing ring. The upper end of the V-shaped air nozzle is connected to the exhaust end of an air pump mounted on the upper left side of the top plate via a corrugated hose. The air inlet end of the air pump is fixedly connected to the exhaust end of a vacuum cleaner mounted on the right side of the top plate via a pipe. The air inlet end of the vacuum cleaner is connected to the lower right edge of the trapezoidal dust collection hood via a pipe. The front end of the bidirectional lead screw is fixedly connected to the output shaft of a motor mounted outside the transparent plate on the front side.

[0005] As a preferred embodiment of this utility model, the left and right sides and the top of the trapezoidal dust collection hood respectively seal and connect the front and rear reinforcing rods on the right side and the top plate at the top; by adopting the trapezoidal dust collection hood, the candy dust raised by the V-shaped jet nozzle on the left side can easily enter the trapezoidal dust collection hood with the negative pressure airflow on the right side for collection.

[0006] In a preferred embodiment of this utility model, the top of the U-shaped moving block is threadedly connected to the bidirectional lead screw, and the top of the U-shaped moving block is movably fitted with the guide post.

[0007] As a preferred embodiment of this utility model, U-shaped limiting grooves are installed on the front and rear sides of the lower end of the left outer wall of the U-shaped moving block, and the rack is movably inserted into the U-shaped limiting grooves.

[0008] As a preferred embodiment of this utility model, the upper end of the corrugated hose penetrates through the top plate; by using a corrugated hose, it is convenient for the V-shaped jet nozzles to continuously supply air to the V-shaped jet nozzles when they move back and forth and rotate.

[0009] As a preferred embodiment of this utility model, the vacuum cleaner is a vacuum cleaner with a built-in air filter.

[0010] The beneficial effects of this utility model are as follows: By controlling the rotation of the motor, the bidirectional lead screw is driven to rotate clockwise and counterclockwise, which in turn drives the front and rear U-shaped moving blocks to move back and forth, thereby driving the front and rear V-shaped jet nozzles to blow air into the left space of the pressing assembly on the upper part of the base. During the back and forth movement of the front and rear V-shaped jet nozzles, the micro electric actuator is controlled to drive the rack to move up and down, which in turn drives the gear to rotate clockwise and counterclockwise. The gear drives the rotating shaft, the fixed ring, and the elevation angle of the V-shaped jet nozzles to change back and forth. The high-speed gas ejected from the V-shaped jet nozzles then blows air into the space to the right of the V-shaped jet nozzles and... The tableting assembly is fully covered in all corners to lift the candy dust inside. The vacuum cleaner on the upper right side of the top plate is controlled to create a negative pressure airflow inside the trapezoidal dust collection hood. This creates a left-to-right airflow between the transparent plate on the left and the trapezoidal dust collection hood, which carries the lifted candy dust through pipes to the air filter in the vacuum cleaner for filtration. The filtered air is then sent back through pipes to the air pump and circulated into the enclosed space above the base. This not only avoids pollution caused by the introduction of external air but also automatically filters the candy dust generated during the tableting process. Attached Figure Description

The four corners of the top plate 13 are fixedly connected to the four corners of the base 11 by reinforcing rods 14. A downwardly inclined baffle 15 is fixedly disposed on the outer side of the right edge of the upper part of the base 11. A trapezoidal dust collection hood 16 is sealed and installed on the upper part of the baffle 15. The left, right, and top sides of the trapezoidal dust collection hood 16 respectively seal the front and rear reinforcing rods 14 on the right side and the top plate 13 on the upper part. The remaining adjacent reinforcing rods 14 are connected, and transparent plates 17 are installed between them respectively. A dust-blowing mechanism 2 is inserted into the upper left corner of each of the front and rear transparent plates 17. The dust-blowing mechanism 2 includes a bidirectional lead screw 21 inserted into the front and rear transparent plates 17. A guide post 22 is fixedly installed between the front and rear plates on the right side of the bidirectional lead screw 21. U-shaped moving blocks 23 are movably fitted on the front and rear sides of the bidirectional lead screw 21 and the guide post 22 respectively. The top of the U-shaped moving block 23 is threadedly connected to the bidirectional lead screw 21, and the top of the U-shaped moving block 23 is movably fitted to the guide post 22. An L-shaped notch 231 is opened on the left side wall and the lower middle part of the U-shaped moving block 23. U-shaped limiting grooves 232 are installed on the front and rear sides of the lower left outer wall of the moving block 23. A rotating shaft 24 is inserted into the front and rear sides of the horizontal section of the L-shaped notch 231. A fixing ring 25 is provided in the middle of the rotating shaft 24. Gears 26 are fixed on the rotating shaft on opposite sides of the fixing rings 25. The left edge of the gear 26 passes through the L-shaped notch 231 and meshes with the teeth of a rack 27 movably installed on the left outer wall of the U-shaped moving block 23. The rack 27 is movably inserted into the U-shaped limiting groove 232. The upper end of the rack 27 is fixedly connected to the telescopic shaft of a miniature electric actuator 28 installed on the upper left outer wall of the U-shaped moving block 23. The fixing ring 25 is fixed within the rack 24. The set includes a V-shaped jet nozzle 29. The upper end of the V-shaped jet nozzle 29 is connected to the exhaust end of the air pump 4 installed on the upper left side of the top plate 13 via a corrugated hose 3. The upper end of the corrugated hose 3 passes through the top plate 13, and the length of the corrugated hose 3 allows the V-shaped jet nozzle 29 to move back and forth. The air inlet end of the air pump 4 is fixedly connected to the exhaust end of the vacuum cleaner 5 installed on the right side of the top plate 13 via a pipe. The vacuum cleaner 5 is a vacuum cleaner with a built-in air filter. The air inlet end of the vacuum cleaner 5 is connected to the lower right edge of the trapezoidal dust collection cover 16 via a pipe. The front end of the bidirectional lead screw 21 is fixedly connected to the output shaft of the motor 6 installed outside the transparent plate on the front side.

[0017] The working principle of this utility model is as follows: During the production of compressed candy, the air pump 4 and vacuum cleaner 5 are started, and the motor 6 is controlled to rotate clockwise and counterclockwise in a regular manner, driving the bidirectional lead screw 21 to rotate back and forth. The U-shaped moving blocks 23 move back and forth along the guide column 22. The high-pressure gas generated by the air pump 4 is ejected at high speed from the front and rear V-shaped nozzles 29 through the pipe and corrugated hose 3. At the same time as the back and forth movement, the micro electric push rod 28 is controlled to drive the lower rack 27 to move up and down back and forth. The rack 27 drives the gear 26 to rotate clockwise and counterclockwise, which in turn drives the rotating shaft 24. The angles of the fixed ring 25 and the V-shaped jet nozzle 29 change repeatedly, allowing the high-speed gas ejected from the V-shaped jet nozzle 29 to fully cover the space on its right side and all corners of the pressing assembly 12, thereby raising the scattered candy powder. At the same time, the vacuum cleaner 5 generates a negative pressure airflow to the right in the space on the left side of the trapezoidal dust collection hood 16. The negative pressure airflow carries the raised candy powder through the pipe into the vacuum cleaner 5, where it is filtered by the internal filter. The filtered air then enters the air pump 4 through the pipe for recycling.
