Description

Technical Field

[0001] This utility model relates to the field of feeding machine technology, and more specifically, to a feeding component of a screw forced feeder. Background Technology

[0002] A forced feeder is an automated device primarily used to replace manual feeding operations, ensuring uniform and safe feeding. It uses a screw conveyor to uniformly and continuously feed materials into processing equipment, such as plastic granulators, thus avoiding the unevenness and safety hazards that can occur with manual feeding.

[0003] A search revealed a utility model patent with publication number CN209952793U, which discloses a forced feeder. The forced feeder includes a conical hopper with a feed inlet at the top. The hopper is characterized by a stirring motor at the top, a stirring rod along its central axis driven by the stirring motor, a stirring paddle vertically connected to the stirring rod, and a spiral feeding rod coaxially connected to the lower end of the stirring rod, extending downwards out of the hopper. This forced feeder can be installed above the feed inlet of an extruder for forced feeding. The stirring motor drives the stirring rod, along with the stirring paddle and the spiral feeding rod, to rotate, thus stirring the added material and forcibly feeding it vertically in a forward direction.

[0004] However, the above patent still has the following shortcomings: when the material is forcibly fed by the spiral feeding rod, the material will be squeezed into a ball, which will affect the subsequent processing of the material; in addition, since the feeding position is fixed, it is not convenient to disperse the material into the processing equipment. Therefore, we have proposed a feeding component of a spiral forced feeder. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a feeding component for a screw forced feeder.

[0006] To solve the above problems, the present invention adopts the following technical solution: a feeding assembly of a spiral forced feeder, including a feeding hopper, a feeding pipe fixedly connected to the bottom of the feeding hopper, a dispersing mechanism provided on the outer side of the bottom end of the feeding pipe, a servo motor fixedly installed on the top surface of the feeding hopper, the output shaft of the servo motor extending into the inner cavity of the feeding hopper and fixedly connected to a transmission column, the bottom end of the transmission column penetrating through the feeding pipe and extending below the feeding pipe and fixedly connected to a conical guide block, multiple cutting blades fixedly connected to the side of the bottom end of the transmission column, and a spiral blade fixedly connected to the side of the transmission column and located in the inner cavity of the feeding pipe.

[0007] As a preferred embodiment of this utility model, the dispersing mechanism includes a bearing fixedly sleeved on the outer side of the bottom end of the feed pipe, a fixing ring fixedly sleeved on the outer side of the bearing, a distributing horn cover fixedly connected to the bottom end of the fixing ring, a plurality of guide plates fixedly connected to the inner wall of the distributing horn cover, a transmission rod fixedly connected to the inner wall of the distributing horn cover, and the end of the transmission rod connected to the side of the transmission column.

[0008] As a preferred embodiment of this utility model, the top surface of the feeding hopper is provided with a feeding port.

[0009] As a preferred embodiment of this utility model, two connecting plates are fixedly connected to the side of the transmission column and located in the inner cavity of the feeding hopper, and scrapers are fixedly connected to the ends of the two connecting plates, with the outer side of the scrapers fitting against the inner wall of the feeding hopper.

[0010] In a preferred embodiment of this utility model, the side of the spiral blade is in contact with the inner wall of the feed pipe, and the top of the spiral blade is located in the inner cavity of the feed hopper.

[0011] As a preferred embodiment of this utility model, the top surface of the feeding hopper is provided with an exhaust hole.

[0012] Compared with the prior art, the advantages of this utility model are as follows: In this utility model, when the material is pushed out from the feed pipe by the rotation of the spiral blade, the rotating cutting blade driven by the transmission column cuts the material, avoiding the material discharged from the feed pipe from clumping together and affecting the subsequent processing of the material. The material distribution horn cover is driven to rotate along with the transmission column by the transmission rod. The material cut by the cutting blade is thrown onto the inner wall of the material distribution horn cover by the conical guide block. The guide plate on the material distribution horn cover drives the material to rotate horizontally and move downward under the action of the material's own weight, realizing the dispersion and feeding of the material, which has good practicality.

[0022] Please see Figure 1-5 A feeding assembly for a spiral forced feeder includes a feeding hopper 1, a feeding pipe 2 fixedly connected to the bottom of the feeding hopper 1, a dispersing mechanism 10 provided on the outer side of the bottom end of the feeding pipe 2, a servo motor 3 fixedly installed on the top surface of the feeding hopper 1, the output shaft of the servo motor 3 extending into the inner cavity of the feeding hopper 1 and fixedly connected to a transmission column 4, the bottom end of the transmission column 4 penetrating through the feeding pipe 2 and extending below the feeding pipe 2 and fixedly connected to a conical guide block 6, a plurality of cutting blades 7 fixedly connected to the side of the bottom end of the transmission column 4, and a spiral blade 5 fixedly connected to the side of the transmission column 4 and located in the inner cavity of the feeding pipe 2.

[0023] In this embodiment, after the material falls from the bottom of the feed pipe 2, the cutting blade 7 is used to cut and disperse the material to prevent it from clumping together.

[0024] For details, please refer to Figures 1 to 4 The dispersing mechanism 10 includes a bearing 11 fixedly sleeved on the outside of the bottom end of the feed pipe 2. A fixing ring 12 is fixedly sleeved on the outside of the bearing 11. A distributing horn cover 13 is fixedly connected to the bottom end of the fixing ring 12. Multiple guide plates 14 are fixedly connected to the inner wall of the distributing horn cover 13. A transmission rod 15 is fixedly connected to the inner wall of the distributing horn cover 13. The end of the transmission rod 15 is connected to the side of the transmission column 4.

[0025] For details, please refer to Figure 1 The top surface of the feeding hopper 1 is provided with a feeding port 16.

[0026] In this embodiment, the material is added to the feeding hopper 1 through the injection port 16.

[0027] For details, please refer to Figure 5 Two connecting plates 8 are fixedly connected to the side of the transmission column 4 and inside the feed hopper 1. Scrapers 9 are fixedly connected to the ends of the two connecting plates 8. The outer side of the scraper 9 is in contact with the inner wall of the feed hopper 1.

[0028] In this embodiment, the scraper 9 is used to scrape the material on the inner wall of the feeding hopper 1 to ensure that the material can be smoothly discharged by the spiral blade 5.

[0029] For details, please refer to Figure 5 The side of the spiral blade 5 is in contact with the inner wall of the feed pipe 2, and the top of the spiral blade 5 is located in the inner cavity of the feed hopper 1.

[0030] In this embodiment, it is ensured that the material in the feeding hopper 1 can only be pushed out by the spiral blade 5.

[0031] For details, please refer to Figure 1 The top surface of the feed hopper 1 is provided with an exhaust hole 17.

[0032] In this embodiment, the water vapor generated during material processing is discharged through the vent 17.

[0033] Working principle: In use, the material to be fed is first put into the feeding hopper 1 through the feeding port 16. The servo motor 3 is started to drive the transmission column 4, the spiral blade 5, the conical guide block 6, the cutting blade 7, the transmission rod 15, and the scraper 9 to rotate. The scraper 9 scrapes the material on the inner wall of the feeding hopper 1. At the same time, the rotation of the spiral blade 5 pushes the material in the inner cavity of the feeding hopper 1 from the discharge pipe 2 so that the material in the inner cavity of the feeding hopper 1 falls out. Then, the material falling from the discharge pipe 2 is shredded by the rotating cutting blade 7, and the shredded material falls into the feed pipe 1. The material falls onto the conical guide block 6, and then the material falling onto the conical guide block 6 is thrown outward by the rotation of the conical guide block 6, causing the material to hit the inner wall of the material distribution horn cover 13 and initially disperse the material. Finally, when the transmission column 4 drives the transmission rod 15 to rotate, the transmission rod 15 drives the material distribution horn cover 13 to rotate synchronously. The rotation of the material distribution horn cover 13 and the guidance of the guide plate 14 cause the material to rotate horizontally and move downward under the action of its own weight, so that the material is dispersed and added into the material processing equipment.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
