Description

Technical Field

[0001] This utility model relates to the field of feeding mechanism technology, specifically a feeding mechanism for an automatic packaging machine. Background Technology

[0002] Automatic packaging machines are highly efficient packaging equipment, mainly used in the food, pharmaceutical, chemical, and plant seed industries. They can package various granular and powdery materials. When using an automatic packaging machine, a feeding mechanism is required to transport granular or powdery materials into the machine's storage bin for packaging. However, existing feeding mechanisms still have certain shortcomings.

[0003] In the existing technology, feeding mechanisms are common in automatic packaging machines. When in use, the feeding mechanism can transport various granular and powdery materials through a screw conveyor. Since the height and size of the discharge pipe on the screw conveyor are relatively fixed, when the distance between the top of the automatic packaging machine and the bottom of the discharge pipe is large, it is easy for the powdery material to fall into the storage bin of the packaging machine during the falling process, which can easily cause material loss. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding mechanism for an automatic packaging machine, so as to solve the problem mentioned in the background art that the current feeding mechanisms on the market are difficult to guide and transport materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for an automatic packaging machine, comprising: a support frame, a hopper, a screw conveyor body, a discharge pipe, and a rectangular guide pipe. The top of the support frame is connected to the hopper, the screw conveyor body is installed on the inner side of the support frame, the discharge pipe is connected to the lower end of the screw conveyor body, and a rectangular guide pipe is connected between the screw conveyor body and the hopper. A connecting disc is welded to the outer side of the discharge pipe, a compression spring is connected inside the connecting disc, an L-shaped locking block is connected to one end of the compression spring, a docking block is provided at the bottom of the discharge pipe, a corrugated hose is connected to the bottom of the docking block, a threaded knob is threadedly connected to the inner side of the docking block near the corrugated hose, a connecting shaft is connected inside the docking block, and a connecting plate is rotatably connected to the outer side of the connecting shaft.

[0006] Preferably, the inner diameter of the docking block matches the inner diameter of the discharge pipe.

[0007] Preferably, the connecting plate has a slot inside that matches the size of the end of the L-shaped card block.

[0008] Preferably, a fixed seat is welded to the outside of the rectangular guide tube, and a rotating shaft is connected between the fixed seat and the rectangular guide tube through a bearing. A connecting column and a pinion are respectively connected to the outside of the rotating shaft.

[0009] Preferably, a rotating rod is connected inside the fixed base via a bearing, and a large gear is connected to the rotating rod near the outer side of the small gear.

[0010] Preferably, the bottom of the fixed base is threadedly connected to a threaded post, the top of the threaded post is welded to a T-shaped block, and a toothed plate is movably connected to the outside of the T-shaped block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the L-shaped card block moves, the feeding mechanism of the automatic packaging machine can compress the compression spring. When the compression spring is compressed to its maximum extent, it can pull the two sets of connecting plates toward the L-shaped card block. When the connecting plate moves, it can rotate through the connecting shaft. While the connecting column rotates, it can agitate and disperse the material inside the rectangular guide tube, so that the material blocked inside the rectangular guide tube can fall into the screw conveyor body for conveying. The connecting column can quickly clear the blockage of the material inside the guide tube.

[0012] 1. The feeding mechanism can transport the specified material to the automatic packaging machine through the screw conveyor body. Traditional feeding mechanisms are difficult to guide and transport powdery materials. When the L-shaped clamp moves, it can compress the compression spring. When the compression spring is compressed to its maximum extent, it can pull the two sets of connecting plates towards the L-shaped clamp. When the connecting plate moves, it can be rotated through the connecting shaft. When the connecting plate rotates and moves into the inside of the connecting plate, it can release the L-shaped clamp. When the L-shaped clamp is released, it can be reset by the elasticity of the compression spring. When the L-shaped clamp is reset, its end can be inserted into the connecting plate and the two sets of threaded knobs can be tightened, thereby installing the docking block at the bottom of the discharge pipe. The corrugated hose at the bottom of the docking block can guide and transport the material inside the discharge pipe. The bottom end of the corrugated hose can be placed inside the storage bin of the automatic packaging machine. When the distance between the packaging machine and the discharge pipe is large, the corrugated hose can prevent the loss of powdery materials during transportation.

[0013] 2. Before using the feeding mechanism, the material needs to be poured into the hopper. If a large amount of material accumulates inside the rectangular guide tube, it can easily cause blockage. When the threaded column reverses, it can drive the T-shaped block to rotate away from the large gear. When the T-shaped block rotates, it can pull the toothed plate. When the toothed plate moves, it can slide against the fixed seat. When the toothed plate moves out of the tooth groove of the large gear, it no longer limits the large gear. When the rotating rod rotates, it can drive the large gear to rotate. When the large gear rotates, it can mesh with and drive the small gear to rotate. When the small gear rotates, it can drive the rotating shaft to rotate. At the same time, the rotating shaft can drive the connecting column to rotate inside the rectangular guide tube. When the connecting column rotates, it can agitate and disperse the material inside the rectangular guide tube, so that the blocked material inside the rectangular guide tube can fall into the screw conveyor body for conveying. The connecting column can quickly clear the blockage inside the rectangular guide tube. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 and Figure 5 It is understood that this utility model provides a technical solution: a feeding mechanism for an automatic packaging machine, comprising: a support frame 1, a hopper 2, a screw conveyor body 3, a discharge pipe 4, and a rectangular guide pipe 5. The top of the support frame 1 is connected to the hopper 2, the screw conveyor body 3 is installed on the inner side of the support frame 1, the discharge pipe 4 is connected to the lower end of the screw conveyor body 3, the screw conveyor body 3 and the hopper 2 are connected together by the rectangular guide pipe 5, a connecting plate 6 is welded to the outer side of the discharge pipe 4, and the inner side of the connecting plate 6 is connected to... A compression spring 7 is provided, with an L-shaped locking block 8 connected to one end. A docking block 9 is provided at the bottom of the discharge pipe 4. A corrugated hose 10 is connected to the bottom of the docking block 9. A threaded knob 11 is connected to the inside of the docking block 9 near the corrugated hose 10. A connecting shaft 12 is connected inside the docking block 9. A connecting plate 13 is rotatably connected to the outside of the connecting shaft 12. The inner diameter of the docking block 9 matches the inner diameter of the discharge pipe 4. A slot matching the end size of the L-shaped locking block 8 is opened inside the connecting plate 13.

[0022] In practice, the feeding mechanism can transport the designated material to the automatic packaging machine through the screw conveyor body 3. Traditional feeding mechanisms are difficult to guide and transport powdery materials. When the distance between the packaging machine and the discharge pipe 4 is large, material conveying loss is likely to occur. Before using the feeding mechanism, the top of the connecting block 9 can be moved to the bottom of the discharge pipe 4 so that the bottom of the discharge pipe 4 can fall inside the connecting block 9. At this time, the two sets of L-shaped locking blocks 8 can be pressed closer to each other. When the L-shaped locking blocks 8 move, the compression spring 7 can be compressed. When the compression spring 7 is compressed to its maximum extent, the two sets of connecting plates 13 can be moved closer to each other. When the L-shaped locking block 8 is pulled in the direction of the connecting plate 13, the connecting plate 13 can be rotated through the connecting shaft 12. When the connecting plate 13 rotates and moves into the interior of the connecting disc 6, the L-shaped locking block 8 can be released. When the L-shaped locking block 8 is released, it can be reset by the elasticity of the compression spring 7. When the L-shaped locking block 8 is reset, its end can be inserted into the connecting plate 13 and the two sets of threaded knobs 11 can be tightened. After the threaded knobs 11 are tightened, their ends can be rotated and moved to the outside of the connecting plate 13. At this time, the threaded knobs 11 can limit the connecting plate 13, making it difficult for the connecting plate 13 to loosen, thereby installing the docking block 9 at the bottom of the discharge pipe 4.

[0023] See Figure 1 , Figure 2 and Figure 5It can be seen that the corrugated hose 10 at the bottom of the docking block 9 can guide and convey the material inside the discharge pipe 4. The bottom end of the corrugated hose 10 can be placed inside the storage bin of the automatic packaging machine. When the distance between the packaging machine and the discharge pipe 4 is large, the corrugated hose 10 can prevent the loss of powdery materials during conveying.

[0024] See Figure 1 , Figure 3 and Figure 4 It can be seen that a fixed seat 14 is welded to the outside of the rectangular guide tube 5. A rotating shaft 15 is connected between the fixed seat 14 and the rectangular guide tube 5 through a bearing. A connecting column 16 and a small gear 17 are connected to the outside of the rotating shaft 15 respectively. A rotating rod 18 is connected to the inside of the fixed seat 14 through a bearing. A large gear 19 is connected to the outside of the rotating rod 18 near the small gear 17. A threaded column 20 is threaded to the bottom of the fixed seat 14. A T-shaped block 21 is welded to the top of the threaded column 20. A toothed plate 22 is movably connected to the outside of the T-shaped block 21. The small gear 17 and the large gear 19 form a meshing structure.

[0025] In practice, before using the feeding mechanism, the material needs to be poured into the hopper 2. If a large amount of material accumulates inside the rectangular guide pipe 5, it can easily cause blockage inside the rectangular guide pipe 5, making it difficult for personnel to insert tools into the rectangular guide pipe 5 for unblocking operations, thus affecting the conveying efficiency of the screw conveyor body 3. When the rectangular guide pipe 5 is blocked, the threaded column 20 can be reversed first. When the threaded column 20 is reversed, it can drive the T-block 21 to rotate and move away from the large gear 19. When the T-block 21 rotates and moves, it can pull the toothed plate 22. When the toothed plate 22 moves, it can slide against the fixed seat 14. When the toothed plate 22 moves from the fixed seat 14, it can slide away from the fixed seat 14. When the large gear 19 is removed from its tooth groove, the toothed plate 22 no longer limits the large gear 19, allowing the operator to rotate the rotating rod 18. When the rotating rod 18 rotates, it drives the large gear 19 to rotate. When the large gear 19 rotates, it meshes with and drives the small gear 17 to rotate. When the small gear 17 rotates, it drives the rotating shaft 15 to rotate. At the same time as the rotating shaft 15 rotates, it drives the connecting column 16 to rotate inside the rectangular guide tube 5. At the same time as the connecting column 16 rotates, it agitates and disperses the material inside the rectangular guide tube 5, allowing the blocked material inside the rectangular guide tube 5 to fall into the screw conveyor body 3 for conveying.

[0026] See Figure 1 , Figure 3 and Figure 4 It can be seen that the connecting column 16 can quickly clear the blockage of material inside the rectangular guide pipe 5.

[0027] In summary, when using the feeding mechanism of this automatic packaging machine, the L-shaped clamp 8 can compress the compression spring 7 as it moves. When the compression spring 7 is compressed to its maximum extent, the two sets of connecting plates 13 can be pulled towards the L-shaped clamp 8. When the connecting plate 13 moves, it can be rotated through the connecting shaft 12. The corrugated hose 10 at the bottom of the docking block 9 can guide and convey the material inside the discharge pipe 4. The bottom end of the corrugated hose 10 can be placed inside the storage bin of the automatic packaging machine. When the distance between the packaging machine and the discharge pipe 4 is large, the corrugated hose 10 can prevent the loss of powdery materials during conveying. The connecting column 16 can quickly clear the blockage of material inside the rectangular guide pipe 5.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
