Description

Technical Field

[0001] This utility model relates to the field of feed forming technology, specifically a twin-screw extrusion low-temperature feed forming machine. Background Technology

[0002] During the production process, feed needs to be processed into strips or pellets for easy feeding, which requires the use of feed forming machines.

[0003] Currently, some feed forming machines on the market, such as the utility model patent with authorization announcement number CN219744727U, disclose a discharge head for a feed extrusion pellet mill. This device sets two discharge surfaces with different discharge hole diameters on a circular discharge head. When it is necessary to switch between different discharge hole diameters, it is only necessary to rotate the discharge head to align the discharge surface two with the discharge surface one. The raw material comes out from the discharge hole one and passes through the corresponding discharge hole two to form the desired feed pellet size. However, it cannot control the length of the extruded feed.

[0004] Therefore, we proposed a twin-screw extrusion low-temperature feed forming machine to solve the problems mentioned above. Utility Model Content

[0026] Embodiments of this utility model:

[0027] like Figures 1-6 As shown, this utility model provides a twin-screw extrusion low-temperature feed forming machine, including an extruder body 1, an orifice adjustment mechanism and a length adjustment mechanism. The extruder body 1 is provided with an extrusion discharge pipe 2, and the extrusion discharge pipe 2 is provided with a receiving plate 3. The extruder body 1 adopts a twin-screw extruder.

[0028] like Figures 1-6As shown, the aperture adjustment mechanism is set on the receiving plate 3 to control the feed particle size. The aperture adjustment mechanism includes a connecting shaft 9 connected to the receiving plate 3. One end of the connecting shaft 9 is rotatably connected to an adjustment plate 10. The adjustment plate 10 is provided with multiple evenly distributed discharge surfaces 11. Each discharge surface 11 is evenly distributed with discharge holes 12. The discharge holes 12 on different discharge surfaces 11 are of different sizes. The adjustment plate 10 is provided with a first knob bolt 101, and the adjustment plate 10 is provided with multiple matching holes that are adapted to the first knob bolt 101. The receiving plate 3 is provided with a first screw hole that is threaded to the first knob bolt 101. By removing the first knob bolt 101, the adjustment plate 10 is released from its fixation. Then the adjustment plate 10 can be rotated so that different discharge surfaces 11 contact the opening of the extrusion discharge pipe 2 to control the feed particle size. After adjustment, the first knob bolt 101 is installed again to fix the adjustment plate 10.

[0029] like Figures 1-6As shown, the length adjustment mechanism is mounted on the receiving plate 3 to control the length of the feed. The length adjustment mechanism includes a housing 4 fixed to the receiving plate 3. A rotating shaft 5 and a transmission adjustment assembly 6 are installed inside the housing 4. One end of the rotating shaft 5 is connected to a pelletizing blade 7. A drive motor 8 is mounted on the mechanism. The transmission adjustment assembly 6 includes a transmission disc 61 and a transmission sprocket 62. The transmission disc 61 is sleeved with the rotating shaft 5, and the transmission sprocket 62 is sleeved with the output shaft of the drive motor 8. The transmission disc 61 has an annular groove 611 and multiple compression chambers. 612, an adjusting rod 63 is provided inside the compression chamber 612, and a baffle 64 and a mechanism spring 65 are also provided inside the compression chamber 612. The baffle 64 is connected to the adjusting rod 63. One end of the adjusting rod 63 is connected to an arc-shaped adjusting plate 66, and the other end of the adjusting rod 63 is set with an arc-shaped structure. A transmission chain 67 is provided on the arc-shaped adjusting plate 66 and the transmission sprocket 62. The arc-shaped adjusting plate 66 is provided with teeth 68 that mesh with the transmission chain 67. A rotating ring 69 is provided in the annular groove 611.

The drive motor 8 is started to drive the transmission sprocket 62 to rotate, and the transmission chain 67 cooperates with the toothed 68. The arc-shaped adjusting plate 66 drives the transmission disc 61 to rotate, which in turn drives the rotating shaft 5 and the pelleting knife 7 to rotate. The pelleting knife cuts the feed extruded through the discharge surface 11 into pellets. The rotating adjusting tube 13 drives the rotating ring 69 and the protrusion 70 to rotate, so that the protrusion 70 contacts one end of the arc-shaped structure of the adjusting rod 63, pushing the adjusting rod 63 and the arc-shaped adjusting plate 66 to move, thereby changing the rotation diameter and controlling the rotation speed of the rotating shaft 5 and the pelleting knife 7, thus controlling the length of the extruded feed.

The tensioner 16 includes a structural box 161, a U-shaped plate 162 is movably disposed on the structural box 161, and a compression spring 163 is disposed inside the structural box 161. A tensioning sprocket 164 is disposed on the U-shaped plate 162, and the tensioning sprocket 164 meshes with the transmission chain 67. With this arrangement, as the adjusting rod 63 and the arc-shaped adjusting plate 66 move, the transmission chain 67 is adjusted, and the tensioner 16 automatically tensions the transmission chain 67.

[0031] like Figures 1-6 As shown, an auxiliary sprocket 17 that meshes with the transmission chain 67 is provided inside the housing 4. With this arrangement, the transmission chain 67 can be prevented from falling off the arc-shaped adjustment plate 66 through the cooperation of the auxiliary sprocket 17.
