[0039] The utility model provides a kind of dust extrusion forming machine, reference Figure 1 And Figure 2 Including: dust collection component 1 and the dust forming component 2 being arranged below dust collection component 1;

[0040] Dust collection component 1 includes: inlet hopper 11 and rotating part 12, rotating part 12 is rotatably arranged below the outlet of inlet hopper 11;

[0041] Dust forming component 2 includes: forming cavity 21, forming push head 22 and forming stop block 23;

[0042] Forming cavity upper side is connected with the outlet of inlet hopper 11, and one side is provided with discharge port, and forming push head 22 is movably arranged in forming cavity 21;

[0043] Forming stop block 23 corresponds with forming push head 21, and is movably arranged at one end of discharge port.

[0044] In this embodiment, a dust extrusion molding machine is provided for the extrusion molding of various dust or powder materials. In use, the collected dust at the top enters the hopper, the rotating member provided at the bottom of the hopper stirs the dust at a uniform speed, avoiding the accumulation of dust around the outlet of the hopper due to static electricity, humidity and gravity, causing blockage of the outlet of the hopper; then, the dust falls uniformly under the stirring of the rotating member and enters the molding cavity. Then, the molding stopper is extended to block the discharge port; the molding push head moves in the molding cavity in the first direction, pressing the dust in the molding cavity against the molding stopper, and pressing the dust into a predetermined shape, such as a columnar, strip-shaped or block-shaped solid; next, the molding push head moves in the molding cavity in the second direction, the molding stopper retracts, and the molding push head moves again in the first direction in the molding cavity to push the compacted dust block out of the molding cavity for subsequent transportation or recycling. The compacted dust block has higher density and greatly reduced volume, facilitating storage and transportation; and is not prone to dust scattering due to air convection or vibration. In summary, the dust extrusion molding machine provided by the present application can make the collected dust fall quickly and uniformly, and can extrude and mold the collected dust, facilitating the transportation and recycling of the dust.

[0045] Preferably, referring to Figure 1 , the inlet width of the hopper 11 is greater than the width of the outlet of the hopper 11; the hopper sidewall between the hopper inlet and the hopper outlet is inclined.

[0046] In this embodiment, the inlet width of the hopper is greater than the width of the outlet of the hopper, and the inclined hopper sidewall structure helps the dust to form a uniform flow state when entering the hopper. Through this uniform flow state, the dust can be more uniformly distributed into the dust molding assembly, ensuring the quality consistency of the dust in the compaction molding process; at the same time, the inclined hopper sidewall design utilizes the gravity and inclined flow guiding effect to make the powder slide downward more quickly and smoothly, avoiding the problem of poor feeding caused by dust accumulation.

[0047] Preferably, referring to Figure 1 , the rotating member 12 comprises: a rotating fan blade 12a provided at the bottom outlet of the hopper 11, a rotating shaft 12b and a rotating drive member;

[0048] The rotating shaft 12b penetrates the hopper sidewall and is rotatably arranged on the hopper sidewall;

[0049] The rotating shaft 12b is connected to the rotating fan blade 12a at the first end and connected to the rotating drive member at the second end.

[0050] In this embodiment, the rotary drive member drives the rotary shaft to rotate, and in turn drives the rotary fan blade to rotate, so as to stir and dredge the dust at the bottom of the feeding hopper, so that the dust is smoothly discharged and uniformly flows out; the rotary shaft is arranged through the side wall, thereby providing good axial support for the rotary fan blade, so that the rotary fan blade runs more stably and avoids jamming or deviation. More preferably, the surface of the rotary fan blade is provided with an anti-adhesion coating to reduce deposition or adhesion on the surface of the rotary fan blade, and to reduce the accumulation of dust and the cleaning frequency of the equipment. For example, the anti-adhesion coating material is polytetrafluoroethylene or silicone or polypropylene.

[0051] Preferably, referring to Figure 2 , the forming cavity 21 is a horizontally arranged cylindrical cavity; the diameter of the forming push head 22 is smaller than the diameter of the forming cavity 21, and the forming push head 22 is coaxially arranged with the forming cavity 21 and forms an annular exhaust gap with the forming cavity 21.

[0052] In this example, the forming cavity is a cylindrical cavity, which has structural symmetry itself. When compacting the dust, the internal compression force can be uniformly distributed on the cavity wall, avoiding the problems of incomplete dust forming and uneven density caused by uneven stress, and improving the extrusion forming quality. Since the diameter of the forming push head is smaller than the diameter of the forming cavity, and the forming push head is coaxially arranged with the forming cavity, an annular exhaust gap is formed. During the process of compacting the dust, the air entrained in the dust can smoothly pass through the exhaust gap and be discharged, thereby avoiding air retention and causing incomplete compaction or internal hole defects, and improving the density of the dust compaction forming. In addition, the exhaust gap can avoid excessive compression of the gas in the forming cavity, greatly reducing the additional load of the forming push head caused by gas resistance during movement, reducing the wear of the forming push head and the cavity wall of the forming cavity, and greatly improving the service life of the dust extrusion forming machine. For example, the exhaust gap is 0.2-0.3 mm, which can ensure that the air in the dust is fully discharged, and can effectively prevent the dust from leaking from the exhaust gap.

[0053] Preferably, referring to Figure 1 and Figure 2 , the dust forming assembly 2 further comprises a push head telescopic member 24 and a stop block telescopic member 25.

[0055] The stop block telescopic member 25 is arranged on one side of the forming stop block 23, and the telescopic end is connected with the forming stop block 23.

[0056] The driving force of the push head telescopic member 24 is smaller than the driving force of the stop block telescopic member 25.

[0057] In this embodiment, the push head telescopic part and the block telescopic part provide driving force for the shaped push head and the shaped block respectively; the push head telescopic part is symmetrically arranged on both sides of the forming cavity to provide bilateral symmetric driving force for the shaped push head, which can ensure the movement of the shaped push head along the axis direction of the forming cavity and prevent the shaped push head from tilting or deviating during movement. In use, the block telescopic part is fully extended to press the shaped block tightly against the discharge port of the forming cavity to close the discharge port of the forming cavity; the push head telescopic part is fully retracted, and the shaped push head is located at one end of the forming cavity; then, under the action of gravity and the rotation part, the dust enters the forming cavity from the discharge port of the hopper for filling; after the dust filling is completed, the push head telescopic part is extended to move the shaped push head along the axis of the forming cavity; since the driving force of the push head telescopic part is smaller than that of the block telescopic part, the shaped block can be tightly pressed against the discharge port under the support of the block telescopic part, and the dust is pressed into the forming cavity between the shaped push head and the shaped block to be extruded into a high-density cylindrical dust block; then, the forming telescopic part is retracted to drive the shaped push head to retract, and the block telescopic part is retracted to drive the shaped block to retract, thereby opening the discharge port of the forming cavity; next, the forming telescopic part is extended to move the shaped push head to push the dust block out of the discharge port of the forming cavity; finally, the block telescopic part is fully extended to tightly press the shaped block against the discharge port; the push head telescopic part is retracted, and the shaped push head is located at one end of the forming cavity, thereby completing one working cycle and realizing stable and efficient dust compaction and continuous discharge process. Specifically, the push head telescopic part, the block telescopic part, and the later-described discharge telescopic part are mechanical structures with telescopic function, such as telescopic pneumatic cylinders, telescopic oil cylinders, worm gears, or scissor-type telescopic devices.

[0059] In this embodiment, the discharge telescopic part is additionally arranged above the discharge port of the forming cavity; when the shaped push head moves to push the dust block out of the discharge port of the forming cavity, the discharge telescopic part drives the discharge push head to retract through the telescopic function, thereby cutting off the dust block to avoid the dust block from being retained on the shaped push head or the discharge port due to shape, weight, or strong adhesion, thereby greatly improving the discharge efficiency and quality of the dust block.

[0060] More preferably, referring to Figure 1 and Figure 3 , the dust extrusion forming machine further comprises a connecting assembly 3 arranged above the hopper 11;

[0061] The connecting assembly 3 comprises a connecting side wall 31 and an openable and closable switch piece 32 arranged at the bottom of the connecting side wall;

[0066] The plug plate 32b corresponds to the feeding grooves and is movably arranged on the bottom plate 32a under the pushing of the push rod 32c.

[0067] In this embodiment, the feeding grooves on the bottom plate are arranged at intervals, which ensures that the dust or other materials are evenly distributed in the feeding grooves when entering the molding equipment, and prevents the materials from entering the feeding hopper unevenly. The plug plate corresponds to the feeding grooves and is movably attached to the bottom plate, so that the plug plate can accurately adjust the dust input according to the demand of the material input, optimize the distribution process of the dust input, and improve the molding effect. More preferably, referring to Figure 3 , the plug plate is triangular and the bottom side of the plug plate is equal in width to the feeding grooves; the bottom side of the triangular plug plate is equal in width to the feeding grooves, so that the plug plate can perfectly butt joint with the feeding grooves; at the same time, when the dust falls and accumulates on both sides of the triangular plug plate, the dust will naturally slide down along the side edges and enter the feeding hopper, avoiding the accumulation of dust on the plug plate; the dust accumulated on the bottom plate will be pushed into the feeding grooves along with the movement of the plug plate, and then enter the feeding hopper, greatly improving the dust recovery rate.
