Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

The purpose of providing the following specific embodiments is to facilitate a clearer and more thorough understanding of the disclosure of this utility model, wherein terms indicating direction such as up, down, left, and right refer only to the position of the illustrated structure in the corresponding drawings. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set on" should be interpreted broadly.

[0025] The following description describes preferred embodiments of the present invention; however, the foregoing description is intended to illustrate the general principles of the present invention and is not intended to limit the scope of the present invention. The scope of protection of the present invention shall be determined by the appended claims.

[0026] Please see Figure 1 , Figure 1 This is a first-view structural schematic diagram of the unpacking device 1000 provided in the first embodiment of this utility model. The unpacking device 1000 includes a hopper 10, a bag-breaking cutter 20, and a kneading assembly 50. The bag-breaking cutter 20 is installed inside the hopper 10 and is used to puncture the material bags. Therefore, by providing the kneading assembly 50 on the hopper 10, the kneading assembly 50 can perform a kneading motion on the material bags, thereby reducing the amount of material residue in the material bags and improving the material discharge efficiency and effect.

[0027] The hopper 10 is used to buffer materials. The hopper 10 is configured as a cylindrical structure to ensure uniform processing of materials within it. The hopper 10 can be configured as at least one of a cylindrical structure and a conical structure. In some embodiments, the hopper 10 can also be configured as a prism-shaped structure; however, this embodiment does not impose specific limitations.

[0028] The bag-piercing blade 20 is used to puncture the material bag, allowing the material inside to fall into the hopper 10. Exemplarily, in this embodiment, the bag-piercing blade 20 is installed inside the hopper 10. The unpacking device 1000 also includes a lifting mechanism 30, which is located outside the hopper 10 and is connected to the bag-piercing blade 20 via a transmission mechanism. The lifting mechanism 30 is used to drive the bag-piercing blade 20 to move up and down along the height direction X of the unpacking device 1000 to pierce the material bag.

[0029] The material can be a battery material. Battery materials include a variety of materials, such as, but not limited to, positive electrode materials, negative electrode materials, conductive agents, etc. In this embodiment, the material is illustrated as a battery material. It can be understood that the material can also be other materials, such as food materials, pharmaceutical materials, fertilizer materials, building materials, etc., and the category of the material is not limited here.

[0030] It should be noted that, Figure 1The purpose of this diagram is merely to schematically illustrate the arrangement of the hopper 10, the bag-breaking cutter 20, and the kneading assembly 50, and is not intended to specifically limit the connection positions, relationships, or specific structures of the various components. The diagram is only a schematic representation of the structure of the unpacking device 1000 according to an embodiment of this utility model and does not constitute a specific limitation on the unpacking device 1000. In other embodiments of this utility model, the unpacking device 1000 may include more or fewer components than shown in the diagram, or a combination of certain components, or different components. For example, the unpacking device 1000 may also include, but is not limited to, a hook device, a recycling device, etc. The hook device is used to hook the material bags. The recycling device is used to recycle the material bags after they have been unloaded.

[0031] The kneading assembly 50 is used in the unpacking equipment 1000. The kneading assembly 50 includes a pusher hopper 51 and a drive unit 52. The pusher hopper 51 is used to knead the material bag. The pusher hopper 51 is configured as an integral structure. The cross-sectional area of ​​the pusher hopper 51 along the height direction X perpendicular to the unpacking equipment 1000 gradually decreases from the direction closer to the material bag to the direction farther away from the material bag. The bottom of the pusher hopper 51 is provided with a clearance hole 5101 for the bag-breaking knife 20 to pass through. The drive unit 52 is connected to the pusher hopper 51 and is used to drive the pusher hopper 51 to move up and down along the height direction X of the unpacking equipment 1000 to approach or move away from the material bag.

[0032] The kneading assembly 50 provided in this embodiment of the utility model has several advantages. First, by setting the pusher hopper 51 to move up and down along the height direction X of the unpacking equipment 1000, the risk of interference and collision during the kneading process of the drive component 52 is avoided, thus improving the safety, reliability, and kneading efficiency of the kneading assembly 50, reducing maintenance costs, and reducing energy loss, wear, or noise of the drive component 52 during the kneading process. Second, by setting the cross-sectional area of ​​the pusher hopper 51 along the height direction X perpendicular to the unpacking equipment 1000 to gradually decrease from near the material bag to far away from the material bag, the material around the material bag is concentrated and pushed to the center of the material bag, improving the material discharge efficiency. Third, the pusher hopper 51 is an integral structure, thus realizing the modular setting of the kneading assembly 50, improving the integration, reducing the risk of component loosening during the kneading process, enhancing the structural strength of the pusher hopper 51, extending the service life of the pusher hopper 51, and enabling a closed operation when the pusher hopper 51 is in contact with the material bag, reducing dust emission and protecting worker health and the environment.

[0033] For the sake of accuracy, all references to direction in this article should be expressed in terms of direction. Figure 1For reference, the hopper 10 has a central axis PP. The hopper 10 is supported on a bearing surface parallel to the central axis P of the hopper 10. The term "height direction X" refers to the direction perpendicular to the bearing surface, where the extension direction of the X-axis is the up-down direction (where the positive direction of the X-axis is up). The term "radial direction Y" refers to the direction parallel to the bearing surface, where the extension direction of the Y-axis is the left-right direction (where the positive direction of the Y-axis is right). For ease of description, the up-down and left-right directions in this utility model are relative positions and do not constitute a limitation. The height direction X and radial direction Y can be customized according to the specific structure of the product and the perspective presented in the accompanying drawings; this utility model does not impose specific limitations.

[0034] In this embodiment, the drive component 52 is located outside the hopper 10. Therefore, by positioning the drive component 52 on the outside of the hopper 10, material contamination of the drive component 52 is avoided, extending its service life and operational reliability, and reducing maintenance costs. In some embodiments, the kneading assembly 50 may further include a sealing cover. The sealing cover is positioned outside the drive component 52, thereby preventing material contamination of the drive component 52, extending its service life and operational reliability, and reducing maintenance costs. The drive component 52 may also be located inside the hopper 10.

[0035] For example, in this embodiment, the drive unit 52 is mounted on the hopper 10. Thus, when the drive unit 52 is mounted on the hopper 10, the integration between the hopper 10 and the kneading assembly 50 is improved, the maintenance process is simplified, and downtime is reduced.

[0036] In some other embodiments, the unpacking device 1000 also includes a frame (not shown). A drive unit 52 is mounted on the frame; alternatively, the drive unit 52 is mounted on both the hopper 10 and the frame. Thus, when the drive unit 52 is mounted on the frame, the frame, as a rigid structure, can withstand greater reaction forces, preventing the hopper 10 from deforming and causing positioning deviations in the drive unit 52. This improves the reliability and smoothness of the drive unit 52 driving the pusher hopper 51 to reciprocate along the height direction X of the unpacking device 1000.

[0037] In this embodiment, the pusher hopper 51 is integrally formed. This integral forming eliminates stress concentration points that may arise from traditional welding or bolted connections, preventing weld cracking or bolt loosening caused by the pushing motion of the pusher hopper 51. Furthermore, the overall structure of the pusher hopper 51 distributes the load more evenly, improving its resistance to deformation and fatigue. On the other hand, the integral design also avoids seams, preventing material leakage, reducing maintenance frequency and replacement costs, and preventing material residue, thus reducing cleaning difficulty and maintenance time.

[0038] Please refer to the following: Figure 2 and Figure 3 , Figure 2 This is a first-view structural schematic diagram of the unpacking device 1000 provided in the second embodiment of this utility model; Figure 3 yes Figure 2 An enlarged view of part I of the unpacking device 1000. In the second embodiment, the structure of the unpacking device 1000 is similar to that of the unpacking device 1000 in the first embodiment, except that the pusher hopper 51 includes multiple pusher plates 515 and at least one connector 516. The multiple pusher plates 515 are fixedly connected by at least one connector 516 to form an integral structure. Therefore, on the one hand, when a single pusher plate 515 is damaged, it is not necessary to replace the entire pusher hopper 51; only the specific plate needs to be replaced, reducing maintenance costs. On the other hand, by increasing or decreasing the number of pusher plates 515 or adjusting the connection method, it can quickly adapt to hoppers 10 of different sizes, and reduces the difficulty of processing and manufacturing.

[0039] In this embodiment, multiple pusher plates 515 are arranged to form a trumpet-shaped structure. A connector 516 is configured as a connecting plate, which is fixedly connected to the gap between two adjacent pusher plates 515. Therefore, the connecting plate reduces the risk of powder escaping from the gap between the two pusher plates 515. Furthermore, the connecting plate protrudes relative to the pusher plates 515, thereby disrupting the continuous contact between the material and the kneading surface 512, preventing material adhesion and accumulation, and improving the material bag's feeding efficiency. Of course, in some embodiments, the connector 516 can also be configured as a connecting ring or a locking screw. Multiple pusher plates 515 are stacked circumferentially and fixedly connected by the connector 516.

[0040] Please refer to it again. Figure 1 and Figure 2 The hopper 51 can be configured as, but is not limited to, a truncated cone or a frustum pyramid structure. This allows the material to slide down naturally under gravity, and the converging cone design concentrates the material towards the clearance hole 5101, preventing material residue from the edges of the bag and improving material discharge efficiency. The truncated cone structure avoids corner accumulation, and the curved surface disperses lateral pressure, providing strong resistance to deformation and making it suitable for high loads. The polygonal cross-section of the frustum pyramid structure disrupts the rotational flow of the material, preventing centrifugal accumulation.

[0041] In some embodiments, the pusher hopper 51 includes a kneading surface 512 for abutting against the material bag. The kneading surface 512 is configured as an arcuate surface and / or a flat surface. Therefore, by configuring the inner wall of the pusher hopper 51 as an arc-shaped surface, on the one hand, the matching degree between the pusher hopper 51 and the material bag shape is improved, ensuring that every corner of the material bag is effectively covered, thus improving the kneading effect; on the other hand, the arc-shaped surface allows the kneading force to be transmitted along the tangential direction, forming a gradual compression, avoiding stress abrupt changes in the planar structure, extending the service life of the pusher hopper 51, and reducing the risk of component loosening during the kneading process, so that the kneading component 50 can still maintain the accuracy of the kneading action after long-term use, extending the service life of the kneading component 50; furthermore, the curved surface of the pusher hopper 51 can generate axial component force during the kneading process, pushing the material to make a spiral motion, thus improving the feeding efficiency; on the other hand, by configuring the inner wall of the pusher hopper 51 as a plane, on the one hand, the plane forms a linear contact zone with the bag body, increasing the local shear stress to break up the clumps of material, thus improving the feeding efficiency; on the other hand, the structure of each plate of the pusher hopper 51 is simple, reducing the processing difficulty.

[0042] For example, in this embodiment, such as Figure 1 As shown, the kneading surface 512 is configured as a continuous smooth surface. This reduces processing difficulty, decreases friction between the material and the pusher hopper 51, extends the service life of the pusher hopper 51, and facilitates cleaning of the pusher hopper 51.

[0043] Please refer to the following: Figure 1 and Figure 4 , Figure 4 This is a first-view structural schematic diagram of the unpacking device 1000 provided in the third embodiment of this utility model. In the third embodiment, the structure of the unpacking device 1000 is similar to that of the unpacking device 1000 in the first embodiment, except that the kneading surface 512 is provided with at least one of a protruding structure 513 and a grooved structure 514. Therefore, on the one hand, the protruding structure 513 and the grooved structure 514 can disrupt the continuous contact between the material and the kneading surface 512, preventing material adhesion and accumulation, and the grooved structure 514 allows slight material flow, reducing dead zones and residual material; on the other hand, the protruding structure 513 generates local shearing on the material during the kneading process, improving the uniformity of material feeding; furthermore, the protruding structure 513 concentrates wear on the protruding parts rather than the entire plane, extending the service life of the pusher hopper 51.

[0044] Understandably, when the hopper 51 moves toward the material bag, the protruding structure 513 can contact the material bag before the hopper 51. The protruding part of the protruding structure 513 relative to the hopper 51 will form a local high-pressure zone during the pushing and kneading process, forcing the material to flow in an alternating manner, effectively breaking up agglomerated material, and improving the feeding effect and efficiency. On the other hand, the protruding part of the protruding structure 513 relative to the hopper 51 can change the stress transmission path of the material bag contact surface, avoiding the central stress concentration phenomenon caused by the conical pushing and kneading of the hopper 51. Furthermore, the protruding part of the protruding structure 513 relative to the hopper 51 and the material bag will have an interlocking effect, reducing the relative slippage between the hopper 51 and the material bag during the pushing and kneading process, and improving the pushing and kneading accuracy and efficiency.

[0045] like Figure 4 As shown, in this embodiment, multiple protrusions 513 and grooves 514 are provided. Each of the protrusions 513 and grooves 514 can be configured as a strip-shaped structure. Multiple protrusions 513 and / or multiple grooves 514 are arranged at intervals along the circumferential direction of the hopper 51, thereby controlling the movement path of the material and causing the material in the material bag to flow towards the clearance hole 5101, improving the feeding efficiency. Of course, in some embodiments, the protrusions 513 and grooves 514 can each be configured as a semi-cylindrical structure or other shapes; this embodiment of the present invention does not impose specific limitations.

[0046] The feed hopper 51 is configured as a non-metallic structure; alternatively, the feed hopper 51 includes a kneading surface 512 for contacting the material bag, the kneading surface 512 being provided with a non-metallic coating. This prevents debris generated from friction between the material bag and the feed hopper 51 from contaminating the material, thus improving material quality. The non-metallic structure may include, but is not limited to, plastic, rubber, or fiber structures.

[0047] For example, in this embodiment, the number of driving members 52 is set to multiple, and the multiple driving members 52 are connected at intervals to the periphery of the pusher hopper 51 on the side away from the avoidance hole 5101. Thus, on the one hand, the driving members 52 are connected to the outer edge of the pusher hopper 51, thereby avoiding the problem of "umbrella-shaped stress distribution" caused by the driving members 52 driving the pusher hopper 51 in the center, so that the material around the material bag is concentrated and pushed to the center of the material bag, improving the pushing and kneading effect of the pusher hopper 51; on the other hand, when the number of driving members 52 is set to multiple, if the material distribution is uneven, the multiple driving members 52 are controlled to move synchronously to evenly transmit the extrusion force, thereby ensuring that the material bag is subjected to consistent force and improving the pushing and kneading effect. Conversely, if the material distribution is uneven, the single-sided pushing force is automatically adjusted to maintain the dynamic balance of the pusher hopper 51 and extend the service life of the pushing and kneading assembly 50.

[0048] In some other embodiments, the number of drive members 52 is set to one, and the drive member 52 is connected to the edge of the pusher hopper 51 away from the clearance hole 5101. Thus, on the one hand, when the number of drive members 52 is set to one, the cost is saved; on the other hand, the drive member 52 is connected to the outer edge of the pusher hopper 51, thereby avoiding the problem of "umbrella-shaped stress distribution" caused by the drive member 52 driving the pusher hopper 51 in the center, so that the material around the material bag is concentrated and pushed to the center of the material bag, improving the pushing and kneading effect of the pusher hopper 51.

[0049] For example, in this embodiment, the number of driving components 52 is set to two, and the two driving components 52 are symmetrically arranged relative to the clearance hole 5101. Therefore, by setting the number of driving components 52 to two, and the two driving components 52 being symmetrically arranged relative to the clearance hole 5101, on the one hand, the pushing force and pushing speed of the pushing hopper 51 are kept synchronized, improving the pushing effect; on the other hand, the torque imbalance caused by unilateral driving is eliminated, making the pushing force distribution of the conical hopper wall on the material bag more uniform, reducing the failure rate of the driving components 52, reducing the maintenance frequency and cost of the pushing assembly 50, thereby improving pushing efficiency, while saving production and maintenance costs.

[0050] It should be noted that the number and location of the driving components 52 can be determined based on factors such as the specifications and dimensions of the thrust bucket, the specifications and dimensions of the material bag, and the type of material. This embodiment of the invention does not impose specific limitations. For example, the number of driving components 52 can also be set to three, four, or more.

[0051] Please refer to the following: Figure 1 and Figure 5 , Figure 5 yes Figure 1 The diagram shows the structure of the unpacking device 1000 from a second-view perspective. The drive unit 52 includes a drive body 521 and an output shaft 522. One end of the output shaft 522 is connected to the drive body 521 for transmission, and the other end is fixedly connected to the pusher hopper 51. Therefore, the fixed connection between the output shaft 522 and the pusher hopper 51 improves transmission efficiency and avoids the problems of elastic deformation and transmission backlash caused by belt, chain, or gear transmissions. This ensures the instantaneous start and stop of the pusher hopper 51's movement, improves the reliability and stability of the pusher hopper 51's lifting and lowering motion relative to the hopper 10, and enhances the spatial compactness of the kneading assembly 50.

[0052] Exemplarily, a fixing seat 511 is provided on the outer wall of the pusher hopper 51, and the fixing seat 511 is detachably and fixedly connected to the output shaft 522. The fixing seat 511 is screwed to the output shaft 522. Of course, the fixing seat 511 and the output shaft 522 can also be detachably and fixedly connected together by means of snap-fit, screw fixing, etc., thereby facilitating the maintenance, replacement, and other operations of the pusher hopper 51 and the drive component 52. Of course, the fixing seat 511 and the output shaft 522 can also be non-detachably connected together, and this embodiment of the utility model does not make a specific limitation.

[0053] In some embodiments, the side edge of the pusher hopper 51 is also provided with a clearance notch 5102. The clearance notch 5102 is used to avoid interference with the functional elements of the unpacking device 1000, thereby preventing the pusher hopper 51 from interfering with the functional elements of the unpacking device 1000 and improving the safety of the pusher assembly 50.

[0054] The drive component 52 can be configured as, but is not limited to, a cylinder, a hydraulic cylinder, a drive motor, a drive gear rack, etc. Exemplarily, in this embodiment, the drive component 52 is configured as a cylinder. The drive body 521 is a cylinder barrel, and the output shaft 522 is a piston rod. Thus, the drive component 52 can directly push the pusher hopper 51 through the piston rod, eliminating intermediate links such as gears and belts, improving the pushing and kneading efficiency. Furthermore, the pneumatic drive can instantly output the rated thrust, and the cylinder itself can absorb vibration, preventing material impact from being transmitted to the drive component 52, extending the service life of the drive component 52 and the hopper 10. The drive component 52 is arranged to avoid interference with the lifting mechanism 30.

[0055] In some embodiments, the kneading assembly 50 further includes a guide 53. The guide 53 is movably connected to the outer wall of the hopper 10 in the height direction X of the unpacking device 1000 and is located outside the hopper 10. The guide 53 is used to guide the output shaft 522 to move along the height direction X of the unpacking device 1000. Thus, on the one hand, by placing the guide 53 outside the hopper 10, debris generated by the lifting and lowering movement of the guide 53 relative to the hopper 10 is prevented from entering the hopper 10, thereby improving the quality of the material; on the other hand, the arrangement of the guide 53 can improve the reliability and smoothness of the output shaft 522 driving the pusher hopper 51 to move back and forth along the height direction X of the unpacking device 1000, thereby improving the continuous kneading effect of the pusher hopper 51.

[0056] In this embodiment, for example, a mounting base 11 is provided on the outer wall of the hopper 10. The mounting base 11 has at least one guide hole 1101 in the height direction X of the unpacking device 1000. The guide member 53 includes a connecting seat 531 and at least one guide shaft 532. The connecting seat 531 is fixedly connected to the output shaft 522 and the at least one guide shaft 532, and each guide hole 1101 is movably inserted into the corresponding guide hole 1101. Thus, the output shaft 522 and the guide shaft 532 are relatively fixedly arranged based on the connecting seat 531, thereby enabling the guide shaft 532 and the output shaft 522 to move synchronously up and down along the height direction X of the unpacking device 1000, improving the guiding effect of the guide member 53, and simplifying the structure.

[0057] For example, in this embodiment, the number of guide members 53 corresponds one-to-one with the number of drive members 52. Each guide member 53 is provided with two guide rods, which are located on both sides of the output shaft 522, thereby improving the guiding effect of the guide member 53 on the output shaft 522. It should be noted that the number and position of the guide rods can be set according to the actual situation, and this embodiment of the utility model does not make a specific limitation. For example, each guide member 53 may also include one, three or more guide rods.

[0058] The drive unit 52 is mounted on the mounting base 11. Specifically, the drive body 521 is fixedly mounted on the mounting base 11, thus eliminating the need for an additional mounting structure to install the drive unit 52 and improving the overall compactness of the unpacking device 1000. Of course, in some embodiments, the drive body 521 can also be mounted on the hopper 10 via an additional support, and this embodiment of the present invention does not impose specific limitations.

[0059] In some embodiments, the kneading assembly 50 further includes a bearing 533. The bearing 533 is mounted on the mounting base 11 and sleeved on the outside of the output shaft 522 and / or the guide shaft 532, thereby reducing the friction between the output shaft 522 and / or the guide shaft 532 and the mounting base 11, and thus improving the reliability and stability of the output shaft 522 driving the pusher hopper 51 to perform lifting and lowering movements.

[0060] In some embodiments, the kneading assembly 50 further includes a telescopic sleeve. One end of the telescopic sleeve is fixedly connected to the drive body 521, and the other end of the telescopic sleeve is fixedly connected to the material hopper 10. The telescopic sleeve is fitted onto the outside of the output shaft 522. This prevents material from entering the drive body 521 or the mounting base 11, improving the reliability and smoothness of the movement of the output shaft 522 relative to the drive body 521 and the mounting base 11.

[0061] In some embodiments, the guide member 53 includes only a guide shaft 532. The guide shaft 532 is fixedly connected to the hopper 10 or the drive body 521. The guide shaft 532 is provided with a guide hole 1101 in the height direction X of the unpacking device 1000, and the output shaft 522 is movably inserted into the guide hole 1101. Thus, on the one hand, the guide shaft 532 and the output shaft 522 slide together, thereby improving the reliability and smoothness of the drive member 52 driving the pusher hopper 51 to move back and forth in the height direction X of the unpacking device 1000, and thus improving the continuous pushing and kneading effect of the pusher hopper 51; on the other hand, the guide shaft 532 is fixedly connected to the hopper 10 or the frame, and is provided with a guide hole 1101 that is separated from the inner cavity of the hopper 10. The output shaft 522 is inserted into the guide hole 1101 provided by the guide shaft 532, thereby preventing debris generated by friction between the guide shaft 532 and the output shaft 522 from entering the hopper 10, thereby improving the quality of the material.

[0062] In some embodiments, the kneading assembly 50 further includes a bearing 533, which is disposed at the end of the guide shaft 532 away from the pusher hopper 51 and sleeved on the outside of the output shaft 522. Thus, one end of the guide shaft 532 extends out of the pusher hopper 51 away from the hopper 10. On the one hand, the guide shaft 532 can contact the material bag before the pusher hopper 51. The protruding portion of the guide shaft 532 relative to the pusher hopper 51 forms a local high-pressure zone during the kneading process, forcing the material to flow in an alternating manner, effectively breaking up agglomerated materials, and improving the feeding effect and efficiency. On the other hand, the protruding portion of the guide shaft 532 relative to the pusher hopper 51 can change the stress transmission path of the material bag contact surface, avoiding the central stress concentration phenomenon caused by the conical kneading of the pusher hopper 51. Furthermore, the protruding portion of the guide shaft 532 relative to the pusher hopper 51 and the material bag create an interlocking effect, reducing the relative slippage between the pusher hopper 51 and the material bag during the kneading process, thus improving the kneading accuracy and efficiency.

[0063] The other end of the guide shaft 532 extends out of the hopper 10 away from the side of the pusher hopper 51. On the one hand, this facilitates the alignment and assembly between the guide shaft 532 and the drive component 52, and provides installation points for the installation of other components, thereby improving assembly efficiency and assembly yield. On the other hand, the two ends of the guide shaft 532 are respectively supported between the pusher hopper 51 and the hopper 10, forming a double-support beam structure, which reduces the sway amplitude of the reciprocating pushing and kneading action of the pusher hopper 51.

[0064] In some embodiments, one end of the guide shaft 532 extends out of the pusher hopper 51 away from the hopper 10. Thus, with one end of the guide shaft 532 extending out of the pusher hopper 51 away from the hopper 10, on the one hand, the guide shaft 532 can contact the material bag before the pusher hopper 51. The protruding portion of the guide shaft 532 relative to the pusher hopper 51 forms a local high-pressure zone during the kneading process, forcing the material to flow in an alternating manner, effectively breaking up agglomerated materials, and improving the feeding effect and efficiency. On the other hand, the protruding portion of the guide shaft 532 relative to the pusher hopper 51 can change the stress transmission path of the material bag contact surface, avoiding the central stress concentration phenomenon caused by the conical kneading of the pusher hopper 51. Furthermore, the protruding portion of the guide shaft 532 relative to the pusher hopper 51 and the material bag create an interlocking effect, reducing the relative slippage between the pusher hopper 51 and the material bag during the kneading process, improving the kneading accuracy and efficiency.

[0065] In some embodiments, the other end of the guide shaft 532 extends out of the hopper 10 away from the side of the pusher hopper 51. On the one hand, this facilitates the alignment and assembly between the guide shaft 532 and the drive component 52, and provides mounting points for the installation of other components (such as the bearing 533), thereby improving assembly efficiency and assembly yield. On the other hand, the two ends of the guide shaft 532 are respectively supported between the pusher hopper 51 and the hopper 10, forming a double-support beam structure, which reduces the sway amplitude of the reciprocating pushing and kneading action of the pusher hopper 51.
