Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of animal feed extrusion equipment, specifically an animal powder extruder. Background Technology
[0002] For equipment used for extruding animal feed, the extrusion die needs to be changed according to the actual application scenario, i.e. the type of animal. For example, for aquatic feed, poultry feed and pet food, the applicable particle diameter needs to be adapted to the different types of animals they are used for. Conventional equipment manufacturers will set up multiple extrusion dies for workers to change, but the conventional replacement method is mostly based on flange bolt fixing structure, which is complicated and requires finding the replacement die from the toolbox. Utility Model Content
[0003] To solve the problem of complex extrusion die replacement process mentioned above, this utility model provides an animal powder extruder.
[0004] The technical solution of this utility model is as follows:
[0005] An animal powder extruder includes a drive unit, which is connected to a drive sleeve via a drive wheel. The drive sleeve is inserted into an extrusion cylinder and can rotate. A screw is inserted into the end of the extrusion cylinder away from the drive sleeve, and the end of the screw is inserted into the drive sleeve and rotates synchronously.
[0006] The end of the expanded cylinder away from the drive sleeve is detachably provided with an additional sleeve to restrict the movement of the screw, and the additional sleeve is provided with a reference turntable at a position away from the screw, and the reference turntable is arranged parallel to the central axis of the screw.
[0007] The reference turntable is detachably equipped with a mold turntable concentric with it, and the mold turntable is provided with multiple extrusion hole groups around the center circumference, and the extrusion hole groups are arranged corresponding to the opening of the puffing cylinder.
[0008] Unlike existing replacement methods, this device only requires rotating the mold turntable to replace the extrusion orifice group, thereby enabling the extrusion of different types of particles.
[0009] To prevent displacement of the mold turntable, the two surfaces of the mold turntable that contact the additional sleeve are provided with annular limiting protrusions, the additional sleeve is provided with corresponding grooves, and the mold turntable is provided with clearance notches.
[0010] To ensure the uniformity of extruded particles, only one set of extrusion orifices can be aligned with the opening of the puffing cylinder at any given time.
[0011] To limit the rotation of the mold turntable, the additional sleeve is provided with a locking pin on the side away from the reference turntable, and the mold turntable is provided with a limiting hole corresponding to the locking pin at each extrusion hole group position.
[0012] The additional sleeve and the mold turntable are connected by rotation. The additional sleeve is provided with an arc-shaped groove centered on the center of the reference turntable. The mold turntable is provided with a boss on the side facing the screw. The rotation trajectory of the boss coincides with the groove and is adapted to fit it.
[0013] As a preferred embodiment, the extrusion hole group is located at the center of the boss, and the opening direction of the extrusion hole group is parallel to the length direction of the screw.
[0014] To ensure a smooth extrusion process, the projection of the axial opening of the expanded cylinder falls into the arc-shaped slot.
[0015] The connection between the reference turntable and the mold turntable is achieved by connecting the reference turntable and the mold turntable through multiple bolts arranged circumferentially.
[0016] As a preferred embodiment, the surface of the mold turntable facing away from the screw is a plane.
[0017] The method to achieve the adjustment of extruded particle size is to have different opening sizes for multiple extrusion orifice groups.
[0018] The beneficial effects of this utility model are as follows: This utility model is an animal powder extruder. Unlike the conventional method of setting a single extrusion mold, this device only needs to set a rotating mold turntable structure, and set multiple corresponding extrusion hole groups on the mold turntable. By rotating, different extrusion hole groups can be aligned with the extrusion cylinder to extrude different specifications and types of granules. Moreover, the switching method only requires the insertion of locking pins after rotation. The process is convenient and does not require a special toolbox for storing different types of molds.

[0027] Example 1
[0028] like Figure 1 , 2 The animal powder extruder shown includes a drive unit 1. The drive unit 1 is connected to a drive sleeve 3 via a drive wheel 2. The drive sleeve 3 is inserted into the extrusion cylinder 5 and can rotate. Its structure will not be described in detail and is the main structure of existing extruders. Based on this, in order to facilitate the cleaning of the extrusion cylinder 5 and the replacement of the screw 4, a screw 4 is inserted into the end of the extrusion cylinder 5 away from the drive sleeve 3. The insertion method is in the axial direction of the screw 4, so the insertion operation can be carried out along the opening direction of the extrusion cylinder 5. It should be noted that the end of the screw 4 is inserted into the drive sleeve 3 and rotates synchronously to ensure normal operation.
[0029] The end of the puffing cylinder 5 away from the drive sleeve 3 is detachably provided with an additional sleeve 6 to restrict the movement of the screw 4. The additional sleeve 4 can prevent the screw 4 from leaving the working position during the working process. Moreover, the additional sleeve 6 is fixed to the end of the puffing cylinder 5 by screwing, and can prevent the phenomenon of displacement after being pressed. Furthermore, a reference turntable 7 is provided on the additional sleeve 6 away from the screw 4, and the reference turntable 7 is parallel to the central axis of the screw 4.
[0030] Subsequently, based on the above structure, the reference turntable 7 is further detachably equipped with a mold turntable 8 concentric with it. Therefore, the mold turntable 8 can rotate about the axis of the reference turntable 7. The mold turntable 8 has multiple extrusion hole groups 82 arranged circumferentially around its center, and the extrusion hole groups 82 are correspondingly arranged with the openings of the puffing cylinder 5. By rotating the mold turntable 8, the positions of the extrusion hole groups 82 can be changed, and different extrusion hole groups 82 can be aligned with the puffing cylinder 5 to ensure granulation as an extrusion mold. Furthermore, the extruded particle size can be adjusted by having multiple extrusion hole groups 82 with different opening sizes, such as... Figure 2As shown, by rotating the switch position, you can change the type of extruded granules.
[0031] This method achieves the desired result. Unlike existing replacement methods, this device only requires rotating the mold turntable 8 to replace the extrusion orifice group 82, thereby enabling the extrusion of different types of particles. Moreover, the mold turntable 8 does not need to be replaced during the process; it only needs to be rotated and aligned with the extrusion orifice group 82 in different states with the puffing cylinder 5.
[0032] Example 2
[0033] In addition to the same structure as in Embodiment 1, to further prevent displacement of the mold turntable 8, annular limiting protrusions 83 are provided on the two surfaces of the mold turntable 8 that contact the additional sleeve 6, and the additional sleeve 6 is provided with corresponding grooves, such as... Figure 4 As shown, the mold turntable 8 can be rotated in one position. When pressed, the annular limiting protrusion 83 and the groove cooperate to prevent displacement. This also prevents gaps from forming due to excessive force.
[0034] Based on this, in order to properly install the aforementioned mold turntable 8, a clearance notch 81 needs to be set. During installation, first align the clearance notch 81 with the additional sleeve 6, then rotate to fit the annular limiting protrusion 83 with the groove, and then continue to rotate. Therefore, the aforementioned clearance notch 81 does not need to be equipped with an extrusion hole group 82.
[0035] Both of the above embodiments need to ensure that, in order to ensure the uniformity of the extruded particles, only one extrusion orifice group 82 can be aligned with the opening of the puffing cylinder 5 at the same time, so as to ensure that the produced particles are of the same type and that multiple types do not occur.
[0036] Furthermore, in order to limit the rotation of the mold turntable 8, the additional sleeve 6 is provided with a locking pin 9 on the side away from the reference turntable 7. The mold turntable 8 is provided with a limiting insertion hole corresponding to the locking pin 9 at each extrusion hole group 82 position. During puffing and granulation, the locking pin 9 needs to be inserted into the corresponding limiting insertion hole to avoid the problem of rotation. It can also facilitate the positioning of the extrusion hole group 82 to ensure that its position is directly opposite the puffing cylinder 5.
[0037] Example 3
[0038] In addition to the same structure as in Embodiments 1 and 2, as a preferred embodiment, the additional sleeve 6 is rotatably connected to the mold turntable 8 by means that the additional sleeve 6 is provided with an arc-shaped groove centered on the center of the reference turntable 7, and the mold turntable 8 is provided with a boss on the side facing the screw 4, and the rotation trajectory of the boss coincides with and is adapted to the groove, i.e. Figure 3 ,4 As shown, this method ensures the stability of the connection between the mold turntable 8 and the additional sleeve 6 when the mold is not rotating. In the above structure, the extrusion hole group 82 is located at the center of the boss, and the opening direction of the extrusion hole group 82 is parallel to the length direction of the screw 4, which ensures the smoothness of the granulation process.
[0039] And it should be noted that, such as Figure 3 As shown, in order to ensure a smooth extrusion process, the projection of the hole in the puffing cylinder 5 along the axial direction falls into the arc-shaped slot. That is to say, the hole in the puffing cylinder 5 is smaller than the arc-shaped slot. Therefore, during the puffing and granulation process, it will only be restricted by the extrusion hole group 82, so that the material will be discharged from its hole position.
[0040] As a preferred embodiment, the connection between the reference turntable 7 and the mold turntable 8 is achieved by connecting the reference turntable 7 and the mold turntable 8 through multiple bolts arranged circumferentially. This method facilitates the replacement of the mold turntable 8 and ensures its axial position during installation, avoiding eccentricity.
[0041] Finally, the surface of the mold turntable 8 facing away from the screw 4 is a plane. In the case of partial granulation, a rotating cutter is also needed to cut the material at the opening. The plane setting of the mold turntable 8 can ensure that when rotating to any extrusion hole group 82, an additional rotating cutter can be set without being affected by it.
