Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to an extrusion device for feed processing. Background Technology

[0002] Feed production requires different process parameters and the structure of extrusion and puffing chambers. The principle of the extruder is to use the extrusion propulsion of the non-standard spiral system with unequal pitch to convert mechanical energy into heat energy, so that the material becomes a gel with fluid properties. When the material is extruded to the outlet, the pressure changes from high pressure to normal pressure and from high temperature to normal temperature. This processing method can gelatinize starch, denature proteins, and improve the palatability of feed.

[0003] A feed processing extrusion device is provided in Chinese patent application number 201920467614.9. During use, the feed in the extruder enters the fixed barrel. After the fixed barrel cools the feed, it is difficult to remove the feed from the fixed barrel, which is inconvenient to use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an extrusion device for feed processing, which can uniformly dissipate heat from the material, thereby improving the cooling efficiency of the extruded feed. It is also convenient to discharge the material, thereby improving the efficiency of feed processing and effectively solving the problems in the background art.

[0005] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0006] An extrusion device for feed processing includes a frame, a cooling tank fixed to the top of the frame, an extruder body fixed to the top of the cooling tank via a feed pipe, a discharge pipe fixed to the bottom of the cooling tank, a feeding roller rotatably connected to the inner side of the cooling tank via a bearing, a U-shaped receiving groove evenly distributed on the feeding roller, a stirring unit installed inside the receiving groove, a fan installed at the end of the cooling tank corresponding to the position of the feeding roller, a drive mechanism for driving the feeding roller to rotate installed on the side of the frame, and a PLC controller installed on the side of the frame, the PLC controller being electrically connected to an external power supply for the fan.

[0007] Furthermore, the stirring unit includes a stirring rod and a rotating shaft, with the stirring rod rotatably mounted inside the receiving trough via the rotating shaft.

[0008] Furthermore, the rotating shaft is a hollow shaft.

[0009] Furthermore, the stirring unit also includes a gear and a gear ring, the gear ring being fixed on the cooling tank, and the gear being fixed on the end of the rotating shaft, with the gear meshing with the gear ring teeth.

[0010] Furthermore, the feed roller is hollow inside and its left and right ends are connected.

[0011] Furthermore, the drive mechanism includes a stepper motor, a drive sprocket, a chain, a connecting shaft, and a driven sprocket. The stepper motor is mounted on the side of the frame. The drive sprocket is fixed on the output shaft of the stepper motor. The driven sprocket is fixed to the end of the feed roller through the connecting shaft. The drive sprocket is connected to the driven sprocket via the chain. The stepper motor is electrically connected to a PLC controller.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This extrusion device for feed processing has the following advantages:

[0013] 1. The material is stirred by the stirring unit, which allows for uniform heat dissipation and improves the cooling efficiency of the extruded feed.

[0014] 2. The feeding roller is driven to rotate by the drive mechanism. When the receiving groove on the feeding roller is connected to the feed pipe, the material in the main body of the extruder enters the receiving groove through the feed pipe. When the receiving groove on the feeding roller is connected to the discharge pipe, the material is discharged from the cooling tank. The discharge is convenient, thereby improving the efficiency of feed processing. Attached Figure Description

Detailed Implementation

[0019] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0020] Please see Figure 1-3This embodiment provides a technical solution: an extrusion device for feed processing, including a frame 1, a cooling tank 2 fixed to the top of the frame 1, an extruder body 9 fixed to the top of the cooling tank 2 via a feed pipe 12, a discharge pipe 11 fixed to the bottom of the cooling tank 2, a feeding roller 6 rotatably connected to the inner side of the cooling tank 2 via a bearing 5, a receiving groove 7 evenly opened on the feeding roller 6, the receiving groove 7 being a "U" shaped groove, a stirring unit 4 installed inside the receiving groove 7, a fan 8 installed at the end of the cooling tank 2 corresponding to the position of the feeding roller 6, a drive mechanism 3 for driving the feeding roller 6 to rotate installed on the side of the frame 1, and a PLC controller 10 installed on the side of the frame 1, the PLC controller 10 being electrically connected to an external power supply of the fan 8.

[0021] The mixing unit 4 includes a mixing rod 41 and a rotating shaft 42. The mixing rod 41 is rotatably mounted on the inner side of the receiving trough 7 via the rotating shaft 42, which is a hollow shaft. The mixing unit 4 also includes a gear 43 and a gear ring 44. The gear ring 44 is fixed on the cooling tank 2, and the gear 43 is fixed at the end of the rotating shaft 42. The gear 43 meshes with the gear ring 44. When the feeding roller 6 rotates, the gear 43 meshes with the gear ring 44 for transmission. The gear 43 drives the mixing rod 41 to rotate via the rotating shaft 42, and the mixing rod 41 stirs the material, thereby dissipating heat evenly and improving the cooling efficiency of the extruded feed.

[0022] The feeding roller 6 is hollow inside and its left and right ends are connected. The material inside the extruder body 9 enters the receiving groove 7 on the feeding roller 6 through the feeding pipe 12. Since the feeding roller 6 is hollow inside and its left and right ends are connected, when the fan 8 blows air, the flowing air can dissipate heat and cool down the material in the receiving groove 7.

[0023] The drive mechanism 3 includes a stepper motor 31, a drive sprocket 32, a chain 33, a connecting shaft 34, and a driven sprocket 35. The stepper motor 31 is mounted on the side of the frame 1. The drive sprocket 32 ​​is fixed on the output shaft of the stepper motor 31. The driven sprocket 35 is fixed to the end of the feed roller 6 via the connecting shaft 34, and the drive sprocket 32 ​​is connected to the driven sprocket 35 via the chain 33. The stepper motor 31 is electrically connected to the PLC controller 10, and the output shaft of the stepper motor 31 drives... When the drive sprocket 32 ​​rotates, it is driven by the driven sprocket 35 via the chain 33. The driven sprocket 35 drives the feeding roller 6 to rotate via the connecting shaft 34. When the receiving groove 7 on the feeding roller 6 is in communication with the feed pipe 12, the material in the extruder body 9 enters the receiving groove 7 through the feed pipe 12. When the receiving groove 7 on the feeding roller 6 is in communication with the discharge pipe 11, the material is discharged from the cooling tank 2. This facilitates discharge and improves the efficiency of feed processing.

[0024] The working principle of the extrusion device for feed processing provided by this utility model is as follows: The material in the extruder body 9 enters the receiving groove 7 on the feeding roller 6 through the feeding pipe 12. Since the feeding roller 6 is hollow inside and its left and right ends are connected, when the fan 8 blows air, the flowing air can dissipate heat and cool the material in the receiving groove 7. At the same time, the stirring rod 41 can be made of heat-conducting material, and the rotating shaft 42 is a hollow shaft. The heat on the material is transferred to the inside of the rotating shaft 42 through the stirring rod 41. Then, the flowing air dissipates heat from the rotating shaft 42, thereby cooling the material in the receiving groove 7. The stepper motor 3... The output shaft of 1 drives the drive sprocket 32 ​​to rotate. The drive sprocket 32 ​​is driven by the driven sprocket 35 through the chain 33. The driven sprocket 35 drives the feeding roller 6 to rotate through the connecting shaft 34. When the receiving groove 7 on the feeding roller 6 is in communication with the feed pipe 12, the material in the extruder body 9 enters the receiving groove 7 through the feed pipe 12. When the receiving groove 7 on the feeding roller 6 is in communication with the discharge pipe 11, the material is discharged from the cooling tank 2. When the feeding roller 6 rotates, the gear 43 meshes with the gear ring 44. The gear 43 drives the stirring rod 41 to rotate through the rotating shaft 42. The stirring rod 41 stirs the material, thereby making it heat up evenly.
