[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device provided with a negative pressure adsorption mechanism. Background Art

[0002] A feeding device refers to a device or system that inputs raw materials or articles into production or processing equipment. The feeding device can be operated automatically or manually and is usually used in the process of industrial production and processing. It is applied in the fields of production and processing, such as food processing, chemical industry, pharmaceutical industry, plastic processing, etc. However, when putting powdered materials during production feeding, the powdered materials will float upward and disperse everywhere when entering the feeding device, resulting in material loss. At the same time, it will also cause a large amount of dust to be inhaled by the workers during feeding, endangering their health. Content of the Utility Model

[0003] The purpose of the utility model is to provide a feeding device provided with a negative pressure adsorption mechanism to solve the problem that the powdered materials fly around when entering the feeding device as mentioned in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A feeding device provided with a negative pressure adsorption mechanism, including a funnel box. The funnel box is arranged underground, and the output port of the funnel box is connected to a lifting feeder. One end outer surface of the funnel box is fixedly installed with a roller. A rotating shaft is installed through the outer surface of the funnel box, and the rotating shaft is rotatably connected to the funnel box. One end outer surface of the funnel box is fixedly installed with an output drive motor, and the output end of the output drive motor penetrates through the outer surface of the funnel box. A negative pressure adsorption mechanism is arranged on one end outer surface of the funnel box. Through the negative pressure adsorption mechanism, the powdered materials that fly during feeding will not disperse everywhere, resulting in environmental pollution. At the same time, the probability of the feeding personnel inhaling the powdered materials is reduced.

[0005] Preferably, the negative pressure adsorption mechanism includes: a suction fan. The suction fan is fixedly installed on one end side surface of the funnel box. A filter pulling frame is slidably installed inside the funnel box, and the side surface of the filter pulling frame is attached to the outer surface of the funnel box. The input end of the suction fan is of a hollow design, and through holes are evenly arranged on the outer surface of the input end of the suction fan. The funnel box and the filter pulling frame are connected by bolts.

[0006] Adopting the above technical solution, the suction fan will be started to suck the flying powdered materials into the inside of the funnel box, and the powdered materials will be filtered by the filter pulling frame, so that the flying powdered materials are sucked by the negative pressure of the suction fan and filtered and isolated by the filter pulling frame, preventing the powdered materials from dispersing everywhere and causing waste, and reducing the harm caused by the workers inhaling dust.

[0007] Preferably, threaded rods are rotatably installed at both ends of the hopper box, and one of the threaded rods is connected to the output drive motor. A synchronous pulley is fixedly installed at the end of the threaded rod away from the output drive motor, and a synchronous belt is arranged between the synchronous pulleys. The outer surface of the threaded rod is penetrated and installed with a moving frame, and the moving frame is threadedly connected to the threaded rod. The outer surface of the moving frame is attached to the outer surface of the hopper box, and the hopper box is engaged with the moving frame.

[0008] By adopting the above technical solution, the threaded rods on both sides of the hopper box can be rotated synchronously through the synchronous pulleys and the synchronous belt, driving the moving frame to move stably.

[0009] Preferably, a push cylinder is fixedly installed on the outer surface of the moving frame. A sliding block is slidably installed inside the moving frame, and the sliding block is engaged with the moving frame. The output end of the push cylinder is connected to the sliding block. A plugging needle is fixedly installed on the side surface of the sliding block, and the plugging needle is inserted into the inside of the sliding block.

[0010] By adopting the above technical solution, the push cylinder can contract to drive the sliding block to slide on the moving frame, so that the plugging needle can move and be inserted into the bag to be fed. When the plugging needle is inserted into the sliding block, the stability of the clamped bag can be improved, so that the bag for feeding can be fixed.

[0011] Preferably, a torsion spring is clamped and installed at one end of the rotating shaft close to the output drive motor, and the other end of the torsion spring is inserted into the inside of the hopper box. A nut is threadedly installed on the outer surface of the rotating shaft, and the nut of the rotating shaft is attached to the outer surface of the torsion spring. A steering rod is fixedly installed on the outer surface of the rotating shaft, and the steering rod is engaged with the rotating shaft, and the outer surface of the rotating shaft is attached to the outer surface of the steering rod. A cutting knife is inserted on the side surface of the steering rod, holes are arranged on the outer surface of the cutting knife, and the cutting knife and the steering rod are connected by bolts.

[0012] By adopting the above technical solution, after the moving frame moves and passes through, the clamped feeding bag will pass through the cutting knife and drive the steering rod to rotate, so that the cutting knife automatically cuts open the outer packaging of the feeding bag and the powder automatically falls into the hopper box. And the torsion spring will push the rotating shaft to reset the steering rod. At the same time, when the cutting knife is worn, the bolt can be stepped on and the cutting knife can be pulled out of the steering rod through the holes on the outer surface of the cutting knife for replacement.

[0013] Preferably, a brush is slidably installed on one side of the hopper box close to the filter pull frame, and the side surface of the brush is attached to the side surface of the filter pull frame. A gear is fixedly installed on the outer surface of the rotating shaft, and the gear is concentrically designed with the rotating shaft. The gear is engaged with one end of the brush.

[0014] With the above technical solution, when the outer packaging of the feeding bag passes through the turning rod and rotates, it will drive the rotating shaft to rotate, causing the gear to rotate accordingly. Through the rotation of the gear, the brush engaged with the gear is driven to move in the funnel box, and the torsion spring is used to push the rotating shaft to reset, so that the brush resets, and the brush moves up and down in the funnel box to brush the filtering frame, ensuring the cleanliness of the filtering frame and causing the powder adhered to the filtering frame to fall back into the funnel box again.

[0015] Preferably, a trigger switch is fixedly installed at one end of the funnel box away from the roller, and one end of the trigger switch extends beyond the side surface of the funnel box. An air suction fan is embedded at one end of the funnel box away from the roller, and the side surface of the trigger switch is in contact with the side surface of the moving frame.

[0016] With the above technical solution, after the feeding is completed and the moving frame moves to the other side of the funnel box, it will contact the trigger switch, causing the air suction fan to start and adsorb the empty feeding bag. Then, the pushing cylinder is automatically opened to release the empty feeding bag, so that the feeding bag will not fall into the interior of the funnel box.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: The feeding device provided with a negative pressure adsorption mechanism:

[0018] 1. After the moving frame moves with the powder package and is cut for feeding, the powder in the feeding bag enters the interior of the funnel box, and the scattered powder will be sucked away by the negative pressure of the exhaust fan, and the dust will be filtered by the filtering frame, so that the dust will not be scattered everywhere and wasted, and at the same time, the probability of dust being inhaled by the feeding workers is reduced;

[0019] 2. By the rotation of the output drive motor, the threaded rod and the synchronous pulley will rotate together, and the synchronous pulley will drive the threaded rod on the other side to rotate through the synchronous belt, so that the rotation speeds of the threaded rods on both sides of the funnel box are the same, enabling the moving frame to move smoothly without deviation and getting stuck;

[0020] 3. Through the roller, it is easier to convey the powder package. After the powder package is pushed below the moving frame, the pushing cylinder can be started to drive the sliding block to move and contract in the moving frame, so that the insertion needle is inserted into the powder package to complete the feeding. Then, the moving frame will move to drive the powder package above the funnel box, and the cutting knife will cut the powder package for feeding, and the turning rod will be pushed to drive the rotating shaft to rotate. Subsequently, the torsion spring is used to push the rotating shaft to automatically reset, enabling the gear to rotate reciprocally as the powder package passes through, driving the brush engaged with the gear to move up and down in the funnel box to brush the filtering frame, so that the powder on the outer surface of the filtering frame is brushed and cleaned, maintaining the ventilation volume of the filtering frame and enabling the brushed dust to automatically fall into the funnel box, automatically brushing the filtering frame every time feeding is performed;

[0021] 4. After the feeding is completed, the moving frame will move and fit with the trigger switch, so that the suction fan will suck over the emptied feeding bag, and the pushing cylinder will push the sliding block away, allowing the sliding block to slide inside the moving frame, releasing the emptied powder bag so that the powder bag will not fall into the funnel box.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-6, the present utility model provides a technical solution: a feeding device provided with a negative pressure adsorption mechanism, including a funnel box 1. The funnel box 1 is arranged underground, and the output port of the funnel box 1 is connected to a lifting feeder. A roller 2 is fixedly installed on the outer surface of one end of the funnel box 1. A rotating shaft 11 is installed through the outer surface of the funnel box 1, and the rotating shaft 11 is rotatably connected to the funnel box 1. An output drive motor 3 is fixedly installed on the outer surface of one end of the funnel box 1, and the output end of the output drive motor 3 penetrates through the outer surface of the funnel box 1. A negative pressure adsorption mechanism is arranged on the outer surface of one end of the funnel box 1. Through the negative pressure adsorption mechanism, the flying powder during feeding will not disperse everywhere, resulting in environmental pollution, and at the same time, the probability of the feeding personnel inhaling the powder is reduced.

[0031] During feeding, the powder bag can be moved through the roller 2 so that the powder bag can enter below the moving frame 7 for feeding, reducing the difficulty of feeding.

[0032] The negative pressure adsorption mechanism includes: a suction fan 15, which is fixedly installed on the side surface of one end of the funnel box 1. A filter pull frame 16 is slidably installed inside the funnel box 1, and the side surface of the filter pull frame 16 is in contact with the outer surface of the funnel box 1. The input end of the suction fan 15 is of a hollow design, and through holes are uniformly arranged on the outer surface of the input end of the suction fan 15. The funnel box 1 and the filter pull frame 16 are connected by bolts.

[0033] After the powder bag is cut open, the powder inside the powder bag will fall into the funnel box 1, causing the powder to fly and disperse. At this time, the rotating suction fan 15 will suck away the flying dust, and the dust will not disperse everywhere through the isolation of the filter pull frame 16. The through holes on the outer surface of the input end of the suction fan 15 will increase the suction volume of the wind of the suction fan 15, preventing the dust from dispersing everywhere and wasting the powder, and at the same time reducing the amount of dust inhaled by the feeding workers.

[0034] Threaded rods 4 are rotatably installed at both ends of the funnel box 1, and one of the threaded rods 4 is connected to the output drive motor 3. A synchronous pulley 5 is fixedly installed at the end of the threaded rod 4 away from the output drive motor 3, and a synchronous belt 6 is arranged between the synchronous pulleys 5. A moving frame 7 is installed through the outer surface of the threaded rod 4, and the moving frame 7 is threadedly connected to the threaded rod 4. The outer surface of the moving frame 7 is in contact with the outer surface of the funnel box 1, and the funnel box 1 is engaged with the moving frame 7.

[0035] The rotation of the output drive motor 3 will drive the threaded rod 4 to rotate, and through the synchronous pulley 5 to rotate, the synchronous pulley 5 and the synchronous belt 6 will drive the threaded rod 4 to rotate together, so that the two threaded rods 4 rotate synchronously, driving the moving frame 7 to move smoothly.

[0036] A pushing cylinder 8 is fixedly installed on the outer surface of the moving frame 7. A sliding block 9 is slidably installed inside the moving frame 7, and the sliding block 9 is engaged with the moving frame 7. The output end of the pushing cylinder 8 is connected to the sliding block 9. A plugging needle 10 is fixedly installed on the side surface of the sliding block 9, and the plugging needle 10 is inserted into the sliding block 9.

[0037] The roller 2 enables the powder packet to easily move below the moving frame 7, with one end of the powder packet positioned between the sliding blocks 9. Subsequently, the pushing cylinder 8 can contract to drive the sliding block 9 to move, causing the plugging needle 10 to insert into the powder packet to clamp it. Then, the moving frame 7 can drive the powder packet above the funnel box 1.

[0038] One end of the rotating shaft 11 close to the output drive motor 3 is snap-fitted with a torsion spring 14, and the other end of the torsion spring 14 is inserted into the funnel box 1. A nut is threadedly installed on the outer surface of the rotating shaft 11, and the nut on the rotating shaft 11 is in contact with the outer surface of the torsion spring 14. A steering rod 12 is fixedly installed on the outer surface of the rotating shaft 11, and the steering rod 12 is engaged with the rotating shaft 11, and the outer surface of the rotating shaft 11 is in contact with the outer surface of the steering rod 12. A cutting knife 13 is inserted on the side surface of the steering rod 12, and holes are provided on the outer surface of the cutting knife 13, and the cutting knife 13 and the steering rod 12 are connected by bolts.

[0039] As the moving frame 7 moves, it will drive the powder packet to move together and contact the cutting knife 13, causing the cutting knife 13 to cut open the powder packet and push the steering rod 12, and drive the rotating shaft 11 to rotate to break open the powder packet for automatic feeding. Subsequently, the torsion spring 14 will push the rotating shaft 11 to reset, causing the steering rod 12 to automatically reset. When the cutting knife 13 is worn after long-term use, the bolts can be removed, and through the holes on the outer surface of the cutting knife 13, the cutting knife 13 can be pulled out from the steering rod 12 for replacement.

[0040] A brush 17 is slidably installed on one side of the funnel box 1 close to the filter pulling frame 16, and the side surface of the brush 17 is in contact with the side surface of the filter pulling frame 16. A gear 18 is fixedly installed on the outer surface of the rotating shaft 11, and the gear 18 is concentric with the rotating shaft 11. The gear 18 is engaged with one end of the brush 17.

[0041] As the moving frame 7 rotates the rotating shaft 11 by pushing the steering rod 12, and then the rotating shaft 11 is reset by the torsion spring 14, the gear 18 can automatically rotate reciprocally. Through the reciprocal rotation of the gear 18, the brush 17 engaged with the gear 18 is driven to move up and down inside the hopper box 1, to brush the outer surface of the filter pulling frame 16, removing the powder adsorbed on the outer surface of the filter pulling frame 16. At the same time, the filter pulling frame 16 can be pulled out from the hopper box 1 for replacement or cleaning, so that the filter pulling frame 16 maintains the ventilation volume and the brushed powder automatically falls back into the hopper box 1, enabling the filter pulling frame 16 to be automatically cleaned every time the moving frame 7 feeds materials.

[0042] A trigger switch 19 is fixedly installed at one end of the hopper box 1 away from the roller 2, and one end of the trigger switch 19 extends beyond the side surface of the hopper box 1. An air suction fan 20 is embedded and installed at one end of the hopper box 1 away from the roller 2, and the side surface of the trigger switch 19 is in contact with the side surface of the moving frame 7.

[0043] After the feeding is completed and as the moving frame 7 moves, the moving frame 7 will contact the trigger switch 19, and the air suction fan 20 will be started to adsorb the emptied feeding bag. Subsequently, the pushing cylinder 8 will automatically open and drive the sliding block 9 to move and open, preventing the emptied feeding bag from falling into the hopper box 1.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
