Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material extrusion, in particular to a material extrusion device. BACKGROUND

[0002] Waste material processing is a core link in the field of resource recycling and environmental protection. Realizing the reduction and resource utilization of waste materials is of great significance to improving resource utilization efficiency, reducing environmental load, and promoting the development of circular economy. It is also a key requirement for the sustainable development of industrial production and recycling industry.

[0003] At present, for the processing of waste materials, the direct scattering or simple stacking method is generally used. The operating personnel usually only dump the waste materials in the open air or in a simple container, without using any material extrusion device with a shaping structure and active extrusion function to process them, relying on the natural stacking state to complete the storage.

[0004] However, loose and stacked waste materials have a large volume and occupy a large amount of space, greatly reducing the utilization rate of the site. Waste materials are prone to spillage and scattering during stacking and transportation, not only causing confusion on site management, but also posing safety hazards and environmental pollution risks. At the same time, irregularly shaped waste materials without extrusion treatment cannot meet the requirements of subsequent efficient transportation and batch recycling, seriously restricting the overall efficiency of waste material resource utilization, and contradicting the processing goal of reduction and resource utilization. SUMMARY

[0005] The present application provides a material extrusion device to solve the technical problems of large space occupation, safety and environmental hazards, and low efficiency of subsequent transportation and processing caused by direct scattering or simple stacking of waste materials.

[0027] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0028] In the field of waste material recycling and processing, existing technologies generally employ direct dumping or simple stockpiling methods. These methods typically involve simply dumping materials in open areas or simple containers, which is insufficient to guarantee effective processing when addressing the demands for waste reduction and resource recovery. Loose stockpiles occupy significant space, leading to high storage costs and low land use efficiency. During transport, materials are prone to spillage and scattering, causing environmental pollution and safety hazards. Furthermore, the irregular shape of loose materials makes them unsuitable for efficient subsequent transportation and large-scale processing. This results in inefficient and costly processing, hindering the adaptation to large-scale, standardized resource recycling processes and severely restricting the overall efficiency of waste material resource utilization.

[0029] To address the aforementioned problems, this application provides a material extrusion device that employs a sequential and coordinated operation of a first extrusion mechanism 3 and a second extrusion mechanism 4. The first extrusion mechanism 3 extrudes the material along a first direction. The second extrusion mechanism 4 extrudes the material along a second direction, which is perpendicular to the first direction. By controlling the sequence of operations of the first extrusion mechanism 3 and the second extrusion mechanism 4, the first extrusion mechanism 3 restarts only after the second extrusion mechanism 4 has completed its extrusion stroke, thereby preventing interference between the movements of the first extrusion mechanism 3 and the second extrusion mechanism 4.

[0030] See Figure 1 The material extrusion device includes a shaping chamber 1, a gate 2, a first extrusion mechanism 3, and a second extrusion mechanism 4.

[0031] Specifically, the shaping chamber 1 is the basic structure and forming container of the material extrusion device. The shaping chamber 1 has a cavity for containing the material. The shaping chamber 1 is typically constructed of welded metal sheets to form a frame and wall panels. The cavity of the shaping chamber 1 has an opening at the top for filling with material.

[0032] A baffle 2 is provided on one side of the shaping chamber 1. The baffle 2 is installed on the shaping chamber 1 in an openable and closable manner. When the baffle 2 is in the closed state, the baffle 2 and the shaping chamber 1 together form a closed material extrusion chamber.

[0033] A first extrusion mechanism 3 is provided on the side of the shaping chamber 1 opposite to the baffle 2. The first extrusion mechanism 3 is used to extrude the material in the material extrusion chamber along a first direction. The output end of the first extrusion mechanism 3 can extend into the material extrusion chamber to apply extrusion force.

[0034] The shaping chamber 1 is also equipped with a second extrusion mechanism 4. The second extrusion mechanism 4 is used to extrude the material in the material extrusion chamber along a second direction. The second direction is perpendicular to the first direction. The output end of the second extrusion mechanism 4 can act on the material in the material extrusion chamber.

[0035] In this embodiment, the second extrusion mechanism 4 can be specifically disposed at the top of the shaping chamber 1, and the second direction is from the top of the shaping chamber 1 towards the bottom. The first extrusion mechanism 3 can be specifically disposed on the side of the shaping chamber 1, and the first direction is horizontal.

[0036] Optionally, the specific implementation of the first extrusion mechanism 3 and the second extrusion mechanism 4 can be hydraulically driven, pneumatically driven, or electrically driven, etc. This embodiment does not limit the specific driving form of the first extrusion mechanism 3 and the second extrusion mechanism 4.

[0037] One embodiment of the baffle 2 is rotatably configured, for example, by connecting it to the shaping chamber 1 via a hinge or pivot, enabling it to rotate and open and close around the pivot. When closed, the baffle 2, together with the shaping chamber 1, forms a closed material extrusion chamber; when open, the baffle 2 forms a channel for material to exit.

[0038] It is worth noting that when the material extrusion device is working, the operator must first ensure that the baffle 2 is in the closed position. At this time, the baffle 2 and the shaping chamber 1 form a closed material extrusion chamber. The operator then fills the loose material to be processed into this material extrusion chamber through the opening of the shaping chamber 1.

[0039] After the filling is completed, the second extrusion mechanism 4 is activated. The output end of the second extrusion mechanism 4 moves in the second direction, pressing into the material extrusion chamber and contacting the material. The output end of the second extrusion mechanism 4 continues to move in the second direction, extruding the material in the chamber.

[0040] Subsequently, the first extrusion mechanism 3 is activated. The output end of the first extrusion mechanism 3 moves along the first direction, pressing into the material extrusion chamber and contacting the material. The output end of the first extrusion mechanism 3 continues to move along the first direction, extruding the material within the chamber.

[0041] The material is compacted in a closed material extrusion chamber under the combined extrusion action of the first extrusion mechanism 3 and the second extrusion mechanism 4.

[0042] As can be seen from the above scheme, the material extrusion device provided in this embodiment forms a closed material extrusion chamber by forming a shaping chamber 1 and a closed gate 2. A first extrusion mechanism 3 is located on the side opposite to the gate 2 and is used for extrusion along a first direction; a second extrusion mechanism 4 is located on the shaping chamber 1 and is used for extrusion along a second direction perpendicular to the first direction. The material is subjected to extrusion forces from two orthogonal directions sequentially within this closed chamber, thereby being compacted and shaped. The openable and closable gate 2 not only achieves the closure of the chamber during extrusion but also provides a channel for subsequent unloading.

[0043] In some embodiments, see Figure 2 The barrier gate 2 of the material extrusion device is located on the extension path in the first direction. When the barrier gate 2 is opened, the extruded material is pushed out from the material extrusion chamber through the barrier gate 2 under the drive of the first extrusion mechanism 3.

[0044] Specifically, after the material extrusion device completes the extrusion of the material, the output end of the second extrusion mechanism 4 stops extruding and moves away from the material being extruded. The gate 2 switches from the closed state to the open state. After the gate 2 opens, an outlet is formed on the extension path in the first direction.

[0045] The output end of the first extrusion mechanism 3 remains in contact with the extruded material and continues to move along the first direction, pushing the extruded material to move along the first direction.

[0046] The extruded material is pushed out of the material extrusion chamber through the outlet formed after the gate 2 is opened, driven by the first extrusion mechanism 3.

[0047] In this embodiment, the baffle 2 is located on the extension path in the first direction, clearly defining the path through which the material is pushed out. After the material extrusion device completes the extrusion of the material, the output end of the first extrusion mechanism 3 continues to move along the first direction, pushing the extruded material toward the baffle 2. The baffle 2 is closed during the extrusion operation to form the end wall of the extrusion chamber, and is opened during the unloading operation to form a material channel. Extrusion and unloading are performed continuously by the same first extrusion mechanism 3, and the material is pushed out in a straight line along the first direction. This arrangement eliminates the need for an additional independent drive mechanism for the pushing action during the unloading process, simplifying the device structure and operation steps, and connecting the material compaction stage and the material removal stage into a continuous operation process, thereby improving overall operation efficiency.

[0048] In some embodiments, see Figure 1 One side of the baffle gate 2 of the material extrusion device is rotatably connected to the shaping chamber 1 via the gate hinge 21.

[0049] Specifically, the door hinge 21 is fixedly installed on the shaping chamber 1. A shaft hole or bushing is provided on one side edge of the door stop 2, and the shaft hole or bushing is fitted onto the door hinge 21. The door stop 2 can rotate around the axis of the door hinge 21 through the cooperation between the shaft hole or bushing and the door hinge 21.

[0050] When the material extrusion device requires operation of the stop gate 2, the operator pushes the stop gate 2 to rotate around the door hinge 21. When the stop gate 2 rotates around the door hinge 21 towards the outside of the chamber, the stop gate 2 opens. When the stop gate 2 rotates around the door hinge 21 towards the inside of the chamber, the stop gate 2 closes. When the stop gate 2 is closed, the plate of the stop gate 2 is in contact with the shaping chamber 1, and the stop gate 2 and the shaping chamber 1 together form a closed chamber. When the stop gate 2 is open, an outlet is formed in the extrusion direction of the first pressing mechanism 3.

[0051] In this embodiment, the door stop 2 is provided with a rotational motion around an axis via a door hinge 21 connection. This method ensures that the opening and closing of the door stop 2 is performed along a fixed axis, and the motion trajectory is determined. The door stop 2 can reliably achieve closing and opening through rotation, with a simple structure and easy implementation.

[0052] In some embodiments, see Figure 1 A locking mechanism 22 is provided on the other side of the barrier gate 2 of the material extrusion device. The locking mechanism 22 is used to keep the barrier gate 2 locked to the shaping chamber 1 or to release the locking state.

[0053] Specifically, the locking mechanism 22 may include a movable latch mounted on the stop gate 2 and a lock seat mounted on the shaping chamber 1 and corresponding to the position of the latch. When the latch is inserted into the lock seat, the stop gate 2 and the shaping chamber 1 are locked. When the latch is pulled out of the lock seat, the stop gate 2 and the shaping chamber 1 are unlocked.

[0054] It should be noted that when the material extrusion device needs to fix the gate 2 in the closed position, the operator operates the locking mechanism 22 to lock the gate 2 against the shaping chamber 1. After the locking mechanism 22 is locked, the gate 2 plate is fixed and cannot rotate around the door hinge 21. The gate 2 and the shaping chamber 1 remain tightly fitted, maintaining the closed state of the material extrusion chamber. When the material extrusion device needs to open the gate 2, the operator first operates the locking mechanism 22 to release the lock. After the locking mechanism 22 is released, the fixed constraint between the gate 2 and the shaping chamber 1 is released, and the gate 2 can rotate freely around the door hinge. Subsequently, the operator pushes the gate 2 to rotate around the door hinge to open it.

[0055] This embodiment provides a reliable means of securing the gate 2 by incorporating a locking mechanism 22 on the gate 2. The locking mechanism 22 ensures that the gate 2 is securely locked to the shaping chamber 1 when closed, withstanding the pressure and vibration generated during material extrusion and ensuring the structural integrity and sealing of the extrusion chamber during operation. The locking mechanism 22 can also be quickly released when needed, allowing the gate 2 to be opened and closed. This structure enhances the stability of the gate 2 in the closed state and enables convenient switching between locking and releasing states, improving the safety and controllability of the device operation.

[0056] In some embodiments, see Figure 2 The first extrusion mechanism 3 of the material extrusion device includes a first hydraulic cylinder 31. The cylinder body of the first hydraulic cylinder 31 is fixed to the outer surface of the wall of the shaping chamber 1. The output end of the first hydraulic cylinder 31 penetrates the wall of the shaping chamber 1 and extends into the material extrusion chamber. The portion of the output end of the first hydraulic cylinder 31 extending into the material extrusion chamber is connected to a first pressure plate 32. Driven by the first hydraulic cylinder 31, the first pressure plate 32 extrudes the material in the material extrusion chamber along a first direction. Specifically, the cylinder body of the first hydraulic cylinder 31 is fixedly connected to the side frame or wall of the shaping chamber 1 via a mounting seat. The piston rod of the first hydraulic cylinder 31 passes through the wall of the shaping chamber 1 along the first direction to extend into the material extrusion chamber. The first pressure plate 32 is fixedly connected to the end of the piston rod of the first hydraulic cylinder 31. The plate surface of the first pressure plate 32 is parallel to the inner surface of the corresponding side wall of the shaping chamber 1. It should be noted that when the material extrusion device is working, the piston rod of the first hydraulic cylinder 31 extends. The piston rod of the first hydraulic cylinder 31 pushes the first pressure plate 32 to move along the first direction. The first pressure plate 32 enters the material extrusion chamber and contacts the material. The first hydraulic cylinder 31 continuously applies hydraulic pressure, pushing the first pressure plate 32 to move continuously along the first direction. The first pressure plate 32 transmits the linear thrust generated by the first hydraulic cylinder 31 to the material, extruding the material along the first direction.

[0057] This embodiment utilizes a combination of a first hydraulic cylinder 31 and a first pressure plate 32 to form a specific implementation of the first extrusion mechanism 3. The first hydraulic cylinder 31 provides stable and controllable linear power, while the first pressure plate 32, as the power output terminal, directly contacts and compacts the material. The first pressure plate 32 increases the contact area with the material, resulting in a more uniform pressure distribution. The structure of the first hydraulic cylinder 31 being fixed to the outer surface of the shaping chamber 1 wall ensures a direct and stable power transmission path and achieves penetration of the output end through the chamber wall. This structure concretizes the driving, transmission, and execution functions of the first extrusion mechanism 3, providing a clear and reliable mechanical solution for implementing material extrusion along the first direction.

[0058] In some embodiments, the extrusion surface of the first pressure plate 32 of the material extrusion device is provided with an anti-sticking structure (not shown in the figures). The anti-sticking structure is provided on the plate surface of the first pressure plate 32 that contacts the material.

[0059] Specifically, one embodiment of the anti-stick structure involves providing raised textures, such as multiple regularly or irregularly distributed bumps or strips, on the extrusion surface of the first pressure plate 32. These raised textures can create microscopic gaps during extrusion, reducing the actual contact area between the material and the first pressure plate 32, thereby reducing adhesion.

[0060] Another implementation of the anti-stick structure involves coating the extrusion surface of the first pressure plate 32 with an anti-stick coating. The anti-stick coating can be made of polytetrafluoroethylene (PTFE), ceramic, or other coating materials with low surface energy and high wear resistance. These coatings have low surface energy and a low coefficient of friction, effectively preventing oily, wet, or highly adhesive materials (such as oily metal shavings, wet plastics, sludge-like waste, etc.) from adhering to the surface of the first pressure plate 32 after extrusion.

[0061] It should be noted that during the operation of the material extrusion device, the first pressure plate 32, equipped with an anti-sticking structure, extrudes the material within the material extrusion chamber. During extrusion, the material comes into contact with the anti-sticking structure on the extrusion surface of the first pressure plate 32. When extrusion is complete and the first pressure plate 32 retracts, the presence of the anti-sticking structure reduces the contact area and adhesion force between the extrusion surface of the first pressure plate 32 and the extruded material. This makes it easier for the extruded material to separate from the extrusion surface of the first pressure plate 32, reducing the likelihood of material adhering to the first pressure plate 32.

[0062] This embodiment provides a solution to prevent material adhesion by incorporating an anti-sticking structure on the extrusion surface of the first pressure plate 32. The anti-sticking structure reduces the adhesion force between the extrusion surface and the material by altering the contact interface characteristics between them. When the first pressure plate 32 completes extrusion and retracts, the extruded material can more reliably detach from it. The anti-sticking structure helps ensure that the extruded material is smoothly ejected or dropped, avoiding problems such as poor unloading or the need for manual intervention due to material adhesion, thus improving the operational continuity and automation of the material extrusion device.

[0063] In some embodiments, see Figure 2 The second extrusion mechanism 4 of the material extrusion device includes a second hydraulic cylinder 41. The cylinder body of the second hydraulic cylinder 41 is fixed to the shaping chamber 1. The output end of the second hydraulic cylinder 41 is located in the material extrusion chamber. The output end of the second hydraulic cylinder 41 is connected to a second pressure plate 42. Driven by the second hydraulic cylinder 41, the second pressure plate 42 extrudes the material in the material extrusion chamber along a second direction.

[0064] Specifically, the cylinder body of the second hydraulic cylinder 41 is fixedly connected to the frame or wall of the shaping chamber 1 via a mounting base. The piston rod of the second hydraulic cylinder 41 is arranged along a second direction. The second pressure plate 42 is fixedly connected to the end of the piston rod of the second hydraulic cylinder 41. The surface of the second pressure plate 42 is perpendicular to the second direction.

[0065] It should be noted that when the material extrusion device is working, the piston rod of the second hydraulic cylinder 41 extends. The piston rod of the second hydraulic cylinder 41 pushes the second pressure plate 42 to move in the second direction. The second pressure plate 42 enters the material extrusion chamber and contacts the material. The second hydraulic cylinder 41 continuously applies hydraulic pressure, pushing the second pressure plate 42 to continuously move in the second direction. The second pressure plate 42 transmits the linear thrust generated by the second hydraulic cylinder 41 to the material, extruding the material in the second direction.

[0066] This embodiment utilizes the combination of a second hydraulic cylinder 41 and a second pressure plate 42 to form a specific implementation of the second extrusion mechanism 4. The second hydraulic cylinder 41 provides stable and controllable linear power, while the second pressure plate 42, as the power output terminal, directly contacts and compacts the material. The structure of the second hydraulic cylinder 41 being fixed to the shaping chamber 1 ensures that the power source and the shaping chamber 1 are relatively fixed. The second pressure plate 42 is perpendicular to the plate surface in the second direction, ensuring effective transmission of extrusion force. This structure concretizes the driving, transmission, and execution functions of the second extrusion mechanism 4, providing a clear and reliable mechanical implementation scheme for extruding materials along the second direction.

[0067] In some embodiments, see Figure 2 The material extrusion device also includes a hydraulic station. The hydraulic station is connected to the first extrusion mechanism 3 and the second extrusion mechanism 4 via hydraulic pipelines. The hydraulic station is used to provide hydraulic power to the first extrusion mechanism 3 and the second extrusion mechanism 4.

[0068] The hydraulic power unit is connected to the first extrusion mechanism 3 and the second extrusion mechanism 4 via pipelines. The hydraulic power unit provides hydraulic power. It includes a pump that provides pressure and valves that control the oil circuits. The pipelines deliver pressurized oil to the first extrusion mechanism 3 and the second extrusion mechanism 4, driving their movement.

[0069] When the device is in operation, the hydraulic station is activated. When the first extrusion mechanism 3 needs to be activated, pressurized oil is sent to the first extrusion mechanism 3, driving its output end to move and extrude along the first direction. When the second extrusion mechanism 4 needs to be activated, pressurized oil is sent to the second extrusion mechanism 4, driving its output end to move and extrude in a direction perpendicular to the first direction. After the operation is completed, the oil circuit is switched, and each mechanism returns to its original position.

[0070] This embodiment provides unified power to the two extrusion mechanisms via a hydraulic station. The hydraulic power can be precisely controlled, delivering a large output force that ensures stable and powerful extrusion action, suitable for high-pressure operations.

[0071] In some embodiments, see Figure 3 The sizing chamber 1 of the material extrusion device is provided with several reinforcing ribs 11 on its frame. The reinforcing ribs 11 are fixedly connected to the frame of the sizing chamber 1. The reinforcing ribs 11 are used to enhance the structural strength of the sizing chamber 1.

[0072] Specifically, the frame of the shaping chamber 1 is constructed by welding steel sections. The reinforcing ribs 11 are strip-shaped metal components, such as angle steel, channel steel, or steel plates. The reinforcing ribs 11 are fixed to the side walls, top beams, or columns of the shaping chamber 1 frame by welding or bolting. Several reinforcing ribs 11 are spaced apart on the shaping chamber 1 frame, forming a grid-like or intersecting support structure.

[0073] In this embodiment, the main structure of the shaping chamber 1 is strengthened by installing several reinforcing ribs 11 on its frame. The reinforcing ribs 11, as additional supporting components, effectively improve the ability of the shaping chamber 1 frame to resist bending, torsion, or local buckling caused by internal extrusion loads. This ensures that the shaping chamber 1 maintains its geometric shape and structural integrity under continuous high-pressure operating conditions, providing a stable and reliable forming space for material extrusion, preventing changes in the extrusion chamber size or sealing failure due to frame deformation, thereby guaranteeing long-term stable operation of the extrusion process and consistent forming quality.

[0074] In some embodiments, see Figure 3 The bottom of the shaping chamber 1 of the material extrusion device is provided with a drain hole 12. The drain hole 12 penetrates the bottom plate of the shaping chamber 1. The drain hole 12 is used to drain the liquid in the chamber of the shaping chamber 1.

[0075] Specifically, the drain hole 12 is a circular or rectangular through hole. The drain hole 12 can be located in the center of the bottom plate of the shaping chamber 1 or near the edge. A guide channel or collection container can be connected below the drain hole 12 to receive and guide the drained liquid.

[0076] It should be noted that when the material extrusion device processes materials containing moisture or other liquids, the material is extruded. During the extrusion process, the liquid contained within the material is separated out under pressure. The separated liquid flows downwards under gravity and collects at the bottom of the shaping chamber 1. The drain hole 12 at the bottom of the shaping chamber 1 provides an outlet channel for this collected liquid. The liquid is discharged from the chamber of the shaping chamber 1 through the drain hole 12 and flows into the guide trough or collection container below.

[0077] This embodiment provides a dedicated drainage path for liquids that may be generated during the extrusion process by creating a drainage hole 12 at the bottom of the forming chamber 1. This structure allows the extruded liquid to be separated from the solid material in a timely and effective manner and guided away from the extrusion chamber when extruding moist materials. This helps reduce the accumulation of liquid in the chamber and avoids adverse effects of liquid on subsequent extrusion operations or the quality of the formed material blocks. For example, it prevents the material from becoming loose again due to wetting, or reduces corrosion and contamination of the extrusion mechanism and the inner wall of the chamber, thereby improving the adaptability of the device to handle materials in different states and the ease of cleaning after operation.

The specific implementation methods provided above are only a few examples under the overall concept of this application and do not constitute a limitation on the scope of protection of this application. For those skilled in the art, any other implementation methods extended from the solution of this application without creative effort shall fall within the scope of protection of this application.
