Description

Technical Field

[0001] This utility model relates to the field of feed production technology, specifically to a feed production extruder. Background Technology

[0002] Extruders are widely used in feed, food, and industrial fields due to their versatility. In the feed processing process, extruders are used to extrude feed. However, in the current technology, when extruders are used to granulate different feeds, it is not convenient to adjust the cutter gap as needed, which makes the flexibility and convenience of use less than ideal.

[0003] For example, patent publication number CN218681880U specifically describes an extruder for feed production, including an extrusion box. A screening box is installed on the outer wall of the extrusion box, and a second motor is installed on the inner wall of the screening box. A disc is installed at the output end of the second motor, and a ring is installed on the outer wall of the disc. A limiting plate is installed around the outer wall of the ring, and a placement plate is installed on the outer wall of the limiting plate. This invention, by installing a screening box, addresses the issue that during the feed extrusion process, incompletely extruded or unexpanded feed may accumulate alongside well-expanded feed, thus requiring... The extruded feed is screened and collected for secondary extrusion. When the extruded feed enters the placement plate in the screening box through the discharge chute, the extruded feed accumulates on the placement plate, and the incompletely extruded feed enters the filter screen in the collection box. The filter screen is pulled out, and the incompletely extruded feed is collected for secondary extrusion. This method of extrudering for secondary extrusion has the problem that it is inconvenient to adjust the cutter gap as needed when pelleting different feeds, resulting in less than ideal flexibility and convenience in use.

A discharge pipe 204 is located at the bottom of the housing 201. An adjusting screw 205 is rotatably connected inside the housing 201. An adjusting handwheel 206 is fixedly connected to the end of the adjusting screw 205, and an internal thread is threaded onto the adjusting screw 205. The internal threaded sleeve 207 has a guide seat 208 fixedly connected to its top. A U-shaped frame 209 is slidably connected inside the guide seat 208. Both ends of the U-shaped frame 209 are fixedly connected to the inner wall of the outer shell 201. The internal threaded sleeve 207 is slidably connected to the U-shaped frame 209 via the guide seat 208, thus guiding the movement of the internal threaded sleeve 207. A connecting frame 210 is fixedly connected to the bottom of the internal threaded sleeve 207. A movable sleeve 211 is rotatably connected inside the connecting frame 210 via a bearing. Multiple cutters 212 are fixedly connected to the movable sleeve 211. A [missing information - likely a cutter or blade] is inserted inside the movable sleeve 211. The connecting rod 213 and the movable sleeve 211 have D-shaped grooves inside. The cross-sectional shape of the connecting rod 213 is D-shaped, and the connecting rod 213 matches the D-shaped groove, allowing the movable sleeve 211 to move axially along the connecting rod 213 and rotate through the connecting rod 213. A drive motor 214 is fixedly installed at the end of the connecting rod 213. The drive motor 214 can drive the cutter 212 to rotate through the connecting rod 213 and the movable sleeve 211 to cut and granulate the strip-shaped extruded feed. A scale is fixedly connected to one side surface of the guide seat 208. 215. A scale 215 is fixedly connected to a take-up roller 216 at one end. The take-up roller 216 is rotatably connected to the inner wall of the outer casing 201. A guide roller is provided on one side of the scale 215, which can guide the movement of the scale 215.

Its input terminal is connected to the weighing device 402, and its output terminal is connected to the buzzer 403. When the weighing device 402 reaches the preset value, the control chip activates the buzzer 403 to sound an alarm. The control chip is connected to the buzzer 403. The feed hopper 404 can be placed on the weighing device 402 to receive the feed pellets. When the feed hopper 404 is about to be full, the weighing device 402 weighs the pellets. When the weight reaches the preset value, the buzzer 403 sounds an alarm to prevent feed from overflowing.

[0025] During operation, the extruder body 3 uses the screw 5 to feed the extruded feed to the pelleting plate 202, and the feed is discharged in strips through the discharge hole 203 on the pelleting plate 202. Rotating the adjusting handwheel 206 causes the adjusting screw 205 to rotate, which in turn causes the inner threaded sleeve 207 to move along the U-shaped frame 209. The movement of the inner threaded sleeve 207 causes the connecting frame 210 to move, which in turn causes the movable sleeve 211 to move. The movement of the movable sleeve 211 causes the cutter 212 to move, changing the distance between the cutter 212 and the pelleting plate 202. At the same time, the movement of the inner threaded sleeve 207 causes the scale 215 to move. The reading on the scale 215 can be observed through the transparent window, making the adjustment more intuitive and convenient. The gap of the cutter 212 can be adjusted as needed, thereby improving the flexibility and convenience of use.
