[0002] The feeder includes a mixing chamber and a guide chute. The mixing chamber is connected to the guide chute below. A screw is installed in the guide chute. When the screw rotates, the powder is conveyed out along the screw thread. Controlling the rotation of the screw can control the amount of powder discharged.

[0003] After prolonged operation, existing feeders cause powder to accumulate and compact at the bottom of the feed chute. This affects the normal operation of the screw, making it difficult for the screw to accurately control the amount of powder discharged. Furthermore, the accumulated and compacted powder changes its state and deteriorates, increasing the rate of defective powder output. Summary of the Invention

The twin-screw mechanism includes twin screws. A horizontal discharge pipe is provided at one end of the guide chamber. The cross-sectional dimension of the horizontal discharge pipe is smaller than the cross-sectional dimension of the guide chamber, so as to form a sunken space in the guide chamber below the twin screws. The guide trough is fixedly installed in the sunken space below the twin screws. The upper surface of the guide trough is a double-arc groove, and the double-arc groove is adapted to the twin screws. A gap of no more than 2mm is maintained between the edge of the twin screws and the double-arc groove.

[0006] The main body of the feed hopper is a cylindrical chamber, and the screw drive end of the feed hopper is detachable.

[0007] The guide trough is elongated and its lower surface is attached to and fixedly installed against the inner wall of the sunken space of the guide hopper.

[0008] The twin screws of the twin screw mechanism are parallel to each other and on the same horizontal plane. The twin screws are parallel to the central axis of the feed hopper and are located in the middle of the feed hopper.

[0009] The lower surface of the guide trough is provided with an internal threaded hole, and the guide bin is fixedly connected to the guide trough by bolts.

[0010] The guide trough has three internal threaded holes evenly arranged along its length, and three bolts are correspondingly set on the lower surface of the guide bin to connect with the internal threaded holes of the guide trough.

[0011] The twin screw consists of two screws with opposite thread directions.

[0012] The twin screw extends into a horizontal discharge pipe; the horizontal discharge pipe is connected to a vertical discharge pipe, and the horizontal discharge pipe is configured in a figure-eight shape to match the overall contour of the twin screw.

[0013] The twin-screw mechanism is connected to the power mechanism via a transmission.

[0014] The feeder using a twin-screw output provided by this utility model has a guide chute in the guide bin that effectively supports the powder. The guide chute works in conjunction with the screw, and the screw smoothly pushes the powder out of the guide chute. The operation is stable and there is no accumulation or compaction of material in the guide bin. The screw accurately controls the amount of powder pushed out. Attached Figure Description

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0023] See Figure 1-2 This utility model provides a feeder using a twin-screw output, including: a guide bin 10, a twin-screw mechanism 20, a guide trough 30, and a mixing bin 40. The main body of the guide bin 10 is a cylindrical chamber, and the guide bin 10 is arranged horizontally. The upper part of the guide bin 10 is connected to the lower part of the mixing bin 40.

[0024] like Figure 2-3 The twin-screw mechanism 20 is horizontally installed in the feed hopper 10. The twin-screw mechanism 20 includes twin screws 21. A horizontal discharge pipe 12 is provided at the right end of the feed hopper 10. The cross-sectional dimension of the horizontal discharge pipe 12 is smaller than the cross-sectional dimension of the feed hopper 10, so as to form a sunken space in the feed hopper 10 below the twin screws 21. The feed trough 30 is fixedly installed in the sunken space below the twin screws 21.

[0025] The upper surface of the feed chute 30 is a double-arc groove, which is adapted to the twin screws 21. A gap of no more than 2mm is maintained between the edge of the twin screws 21 and the double-arc groove. The upper surface of the feed chute 30 is the working surface, which carries the powder material and conveys it out under the driving force of the rotation of the twin screws 21.

[0026] The twin screw 21 consists of two screws with opposite thread directions. The two screws of the twin screw 21 are parallel to each other and on the same horizontal plane. The two screws are installed in the middle position inside the feed hopper 10 and are parallel to the central axis of the feed hopper 10.

[0027] like Figure 2-3 The guide trough 30 is long and narrow, and its lower surface is attached to and fixedly installed with the inner wall of the sunken space of the guide bin 10.

[0028] Furthermore, three internal threaded holes are evenly arranged along the length of the lower surface of the guide trough 30, and three bolts 11 are correspondingly set on the lower surface of the guide bin 10 to connect with the internal threaded holes of the guide trough 30.

[0029] like Figure 1-2 The left end face of the feed hopper 10 is detachable, allowing the twin-screw mechanism 20 to be disassembled and installed from the left end face of the feed hopper 10. Similarly, the feed chute 30 can also be disassembled and installed from the left end face of the feed hopper 10. This convenient disassembly and replacement method facilitates the selection of different specifications of twin-screw 21 and feed chute 30 for different powders and granules.

[0030] The left end of the twin-screw mechanism 20 is connected to the power mechanism, which provides rotational power to the twin-screw 21.

[0031] like Figure 1-2 The right end of the twin screw 21 extends into the horizontal discharge pipe 12; the horizontal discharge pipe 12 is connected to the vertical discharge pipe 13, and the horizontal discharge pipe 12 is set in a figure-eight shape that matches the overall outline of the twin screw 21.

[0032] When working, see Figure 2-3 The mixing chamber 40 mixes the powder in it, and the powder enters the feed hopper 10, which is located above the feed trough 30. During the production process, the twin screw 21 rotates according to the production needs, and the powder moves along the thread of the twin screw 21. The twin screw 21 pushes out a certain amount of powder, which enters the vertical discharge pipe 13 through the horizontal discharge pipe 12 and is transported to the subsequent production process.

[0033] In summary, the feeder using a twin-screw output of this utility model has a good material guide chute in the material guide bin that effectively supports the powder. The material guide chute works in conjunction with the screw, and the screw smoothly pushes the powder out of the material guide chute. The operation is stable and there is no accumulation or compaction of material in the material guide bin. The screw accurately controls the amount of powder pushed out.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
