Description

Technical Field

[0001] The utility model belongs to the field of household appliances, and in particular relates to a powder pressing head and an automatic powder pressing machine. Background Art

[0002] With the improvement of living standards, people prefer to brew drinks manually in their spare time instead of packaged drinks containing various additives on the market, so as to taste more original flavors. For the brewing of powdered drinks, a richer flavor can be obtained through extraction. Whether the extracted taste is balanced mainly depends on whether the compaction degree of the powder is uniform. The compaction effect of the existing automatic powder pressing machine mainly depends on the structure of the powder pressing head.

[0003] Since the powder falls from the powder outlet on the top of the powder pressing machine in an irregular motion, the existing powder pressing head is prone to uneven compaction of the powder. The present application mainly provides a powder pressing head that can evenly distribute the powder. Summary of the invention

[0004] The utility model aims to provide a powder pressing head which can evenly distribute powder and make the powder compacted more evenly.

[0005] The technical solution is as follows:

[0006] A powder pressing head comprises a connecting portion, a powder pressing sheet and a bracket, wherein the powder pressing sheets are distributed along the circumferential direction of the connecting portion and are in an inclined state. The powder pressing sheet has a first end and a second end. In the axial direction of the connecting portion, the first end of the powder pressing sheet is lower than the second end, and the outer edge of the powder pressing sheet is arranged to have a smooth transition; the bracket is bent to form a cantilever section and a connecting section, the cantilever section is connected to the connecting portion, and the connecting section is cooperatively connected to the powder pressing sheet; in the axial direction of the connecting portion, the cantilever section is located on one side of the upper surface of the powder pressing sheet.

[0007] When the powder from above falls onto the working powder pressing head below, a bracket is provided on the upper part of the powder pressing head, which is bent to form a cantilever section and a connecting section. The cantilever section rotates synchronously with the connecting section to first evenly break up the fallen powder and make the powder evenly scattered on the upper surface of the powder pressing tablet. Since the powder pressing tablet is in an inclined state, the first end is at the lowest position and the second end is at the highest position. When the powder pressing tablet rotates synchronously with the connecting section, the powder close to the second end of the powder pressing tablet falls evenly under the powder pressing tablet as the inclined surface rotates. The powder is evenly compacted on the lower surface of the powder pressing tablet to avoid uneven compaction caused by the powder falling directly onto the powder pressing tablet irregularly.

[0008] In one embodiment, the lower surface of the compressed powder tablet is arranged to have an arc-shaped transition from the first end to the second end; and the inclination angle of the lower surface of the compressed powder tablet relative to the horizontal direction gradually decreases from the second end to the first end of the compressed powder tablet.

[0009] The lower surface of the compressed powder tablet is arranged as an arc-shaped transition. When the powder falls into the lower surface of the compressed powder tablet and is compacted, the arc-shaped transition surface can push the powder that has not been compacted to spread more evenly. From the second end to the first end of the compressed powder tablet, the inclination angle of the lower surface of the compressed powder tablet relative to the horizontal direction gradually decreases, so that the powder below the compressed powder tablet close to the first end is more compacted, and the powder that has not been compacted near the second end is pushed more smoothly and evenly, and then rotates along the arc-shaped transition surface to the bottom of the first end and is quickly compacted, further making the compaction more uniform, avoiding the abrupt compaction process of the traditional powder pressing head on the powder on the lower surface, so that the powder that falls first is more compacted, and the powder that falls later is less compacted than the powder that falls first.

[0010] In one embodiment, the pressed powder sheet is provided with a first groove, and the first groove is close to the second end.

[0011] Since multiple compressed powder sheets are distributed along the circumferential direction of the connecting part, after a large amount of powder falls into the upper end of the compressed powder sheet, a first groove is set near the second end of the compressed powder sheet, which can push more uncompacted powder above and gather the powder near the second end, so that the powder near the second end of the compressed powder sheet is pushed to the inclined surface of the adjacent compressed powder sheet, and then falls evenly under the compressed powder sheet for compaction.

[0012] In one embodiment, the first groove is also close to the connecting portion, and the projection of the first groove in the axial direction is an arc shape.

[0013] The first groove is also close to the connecting part. Since the rotating part is connected to the rotating shaft of the powder pressing machine, the thrust close to the connecting part is stronger, which reduces the pushing resistance generated when the first groove of the compressed powder tablet is close to the second end. The first groove is arranged in an arc shape, which further reduces the resistance generated by pushing the powder, makes the pushing smoother, and improves the service life of the compressed powder tablet.

[0014] In one embodiment, the bending degree of the first groove close to the connecting portion is greater than the bending degree of the first groove close to the second end.

[0015] The curvature of the first groove of the compressed powder sheet close to the connecting part is greater than that close to the second end. Since the thrust close to the connecting part is greater, it is beneficial to push more powder close to the connecting part, reduce the pushing pressure of the powder close to the second end, and can also generate an inward centripetal force on the powder close to the second end, producing a gathering effect, further accelerating the powder to fall below the compressed powder sheet as it rotates along the inclined surface for compaction.

[0016] In one embodiment, the compressed powder sheet extends along the first groove toward the lower surface to form a first concave surface; the first concave surface is connected to the upper surface and the lower surface of the compressed powder sheet, and the first concave surface is in an inclined state.

[0017] The first groove extends toward the lower surface to form a first concave surface, and the first concave surface is an inclined surface, which plays a role of guiding transition and is conducive to smoother introduction of the powder pushed by the first groove to the lower side for compaction.

[0018] In one of the embodiments, a scraper is further provided on the outer edge of the connecting section, the scraper protrudes from the outer edge of the compressed powder sheet, and the bottom of the scraper is close to the lower surface of the compressed powder sheet.

[0019] When the powder pressing head is matched with the powder pressing machine, the scraper protruding from the outer edge of the powder pressing sheet can scrape off the powder remaining on the side wall of the powder pressing machine.

[0020] In one embodiment, the connecting section is provided with a first groove body and a second groove body close to the compressed powder sheet; the first groove body abuts against the upper side of the compressed powder sheet, and the lower side of the compressed powder sheet abuts against the second groove body.

[0021] The first groove body abuts against the upper side of the compressed powder sheet, and the lower side of the compressed powder sheet abuts against the second groove body, so that the bracket and the compressed powder sheet are snap-connected, further improving the stability of the connection. Since the cantilever section of the bracket needs to break up the fallen powder, after the connecting section is fixed, the force on the cantilever section can be enhanced, the rigidity of the cantilever section can be improved, thereby increasing the service life of the bracket.

[0022] In one embodiment, the connecting portion includes a first connecting member and a second connecting member, the first connecting member is cooperatively connected to the second connecting member, the pressed powder sheet is connected to the first connecting member, and the bracket is connected to the second connecting member.

[0023] The connecting part is a first connecting piece and a second connecting piece, so that the pressed powder sheet and the bracket can be a split structure, which improves the flexibility of the bracket and the service life of the bracket. In addition, the split structure is convenient for replacing only damaged parts at a later stage, reducing maintenance costs.

[0024] An automatic powder pressing machine comprises a main machine, a powder pressing shaft, a driving motor, a powder cup and the powder pressing head described in any one of the above items, wherein the driving motor is fixedly arranged on the upper part of the main machine, one end of the powder pressing shaft is connected to the driving motor, the powder pressing head is cooperatively connected to the other end of the powder pressing shaft, the lower part of the main machine is connected to the powder cup, the powder pressing head corresponds to the powder cup, the scraper of the powder pressing head abuts against the inner side of the powder cup, and a first hole is provided on one side of the upper part of the main machine, the first hole is located above the powder pressing head, and the first hole corresponds to the powder pressing head.

[0048] like Figures 1 to 11The compressed powder head 1 shown comprises a connecting portion 10, a compressed powder sheet 11 and a bracket 12, wherein the compressed powder sheet 11 is distributed along the circumferential direction of the connecting portion 10, the compressed powder sheet 11 is in an inclined state, and the compressed powder sheet 11 has a first end 111 and a second end 112, and in the axial direction of the connecting portion 10, the first end 111 of the compressed powder sheet 11 is lower than the second end 112, and the outer edge of the compressed powder sheet 11 is configured to be a smooth transition; the bracket 12 is bent to form a cantilever section 121 and a connecting section 122, the cantilever section 121 is connected to the connecting portion 10, and the connecting section 122 is cooperatively connected to the compressed powder sheet 11; in the axial direction of the connecting portion 10, the The cantilever section 121 is located on one side of the upper surface of the compressed powder tablet 11. When the powder from the upper side falls onto the compressed powder head 1 which is in a working state below, the cantilever section 121 rotates synchronously with the connecting portion 10, and first breaks up the fallen powder evenly, so that the powder is evenly scattered on the upper surface of the compressed powder tablet 11. Since the compressed powder tablet 11 is in an inclined state, the first end 111 is at the lowest position and the second end 112 is at the highest position. When the compressed powder tablet 11 rotates synchronously with the connecting portion 10, the powder close to the second end 112 of the compressed powder tablet 11 falls evenly to the bottom of the compressed powder tablet 11 along with the rotation of the inclined surface. The powder is evenly compacted on the lower surface of the compressed powder tablet 11 to avoid uneven compaction caused by the powder falling directly onto the compressed powder tablet 11 irregularly.

[0049] The connecting portion 10 includes a first connecting member 101 and a second connecting member 102, the first connecting member 101 and the second connecting member 102 are cooperatively connected, the compressed powder sheet 11 is connected to the first connecting member 101, and the bracket 12 is connected to the second connecting member 102, so that the compressed powder sheet 11 and the bracket 12 can be a split structure, which improves the flexibility of the bracket 12 and the service life of the bracket 12. In addition, the split structure is also convenient for replacing only damaged parts at a later stage, thereby reducing maintenance costs.

[0050] Focus on combination Figures 1 to 5 As shown, the pressed powder tablet 11 is further described below:

[0051] The upper surface of the compressed powder tablet 11 is set to be an arc-shaped transition between the first end 111 and the second end 112. From the second end 112 to the first end 111 of the compressed powder tablet 11, the inclination angle of the upper surface of the compressed powder tablet 11 relative to the horizontal direction gradually decreases, so that the powder falls from the upper surface of the compressed powder tablet 11 more smoothly to the bottom for compaction; the lower surface of the compressed powder tablet 11 is set to be an arc-shaped transition between the first end 111 and the second end 112. When the powder falls into the lower surface of the compressed powder tablet 11 for compaction, the arc-shaped transition surface can push the powder that has not been compacted to spread more evenly. evenly; from the second end 112 to the first end 111 of the compressed powder sheet 11, the inclination angle of the lower surface of the compressed powder sheet 11 relative to the horizontal direction gradually decreases, so that the powder below the compressed powder sheet 11 close to the first end 111 is more compacted, and the powder near the second end 112 that has not been compacted is pushed more smoothly and evenly, and then rotates along the arc-shaped transition surface to the bottom of the first end 111 and is quickly compacted, so that the compaction is further more uniform, avoiding the abrupt compaction process of the traditional powder pressing head 1 on the powder on the lower surface, so that the powder that falls first is more compacted, and the powder that falls later is less compacted than the powder that falls first.

[0052] Focus on combination Figure 1 , Figure 3 as well as Figure 4 As shown, the first groove 113 is further described below:

[0053] The compressed powder tablet 11 is provided with a first groove 113, and the first groove 113 is close to the second end 112. Since the plurality of compressed powder tablets 11 are distributed in the circumferential direction of the connecting portion 10, after a large amount of powder falls into the upper end of the compressed powder tablet 11, the first groove 113 can push more powder that has not been compacted, and gather the powder close to the second end 112, so that the powder close to the second end 112 of the compressed powder tablet 11 is pushed to the inclined surface of the adjacent compressed powder tablet 11, and then falls evenly under the compressed powder tablet 11 for compaction; the first groove 113 is also close to the connecting portion 10, and the axial projection of the first groove 113 is an arc shape. The first groove 113 is also close to the connecting portion 10. Since the rotating portion is connected to the rotating shaft of the powder press 2, the thrust close to the connecting portion 10 is stronger, thereby reducing the pushing resistance generated when the first groove 113 of the compressed powder tablet 11 is close to the second end 112. The first groove 113 is set to an arc shape, which further reduces the pushing of the powder. The resistance generated makes the pushing smoother and improves the service life of the compressed powder tablet 11; the curvature of the first groove 113 close to the connecting part 10 is greater than the curvature of the first groove 113 close to the second end 112. Since the thrust close to the connecting part 10 is greater, it is beneficial to push more powder close to the connecting part 10, reduce the pushing pressure of the powder close to the second end 112, and can also generate an inward centripetal force on the powder close to the second end 112, produce a gathering effect, and further accelerate the powder to fall and be compacted below it as the inclined surface of the compressed powder tablet 11 rotates; the compressed powder tablet 11 extends toward the lower surface along the first groove 113 to form a first concave surface 114, the first concave surface 114 is connected to the upper surface and the lower surface of the compressed powder tablet 11, and the first concave surface 114 is inclined, which plays a role of guiding transition, which is beneficial to the powder pushed by the first groove 113 to be more smoothly introduced into the lower part for compaction.

[0054] Focus on combination Figure 1 to Figure 2 as well as Figures 6 to 8 As shown, the bracket 12 is further described below:

[0055] The upper part of the cantilever section 121 is provided with an inclined surface, which can reduce the friction between the bracket 12 and the falling powder, and break up the powder more evenly; the outer edge of the connecting section 122 is also provided with a scraper 123, the scraper 123 protrudes from the outer edge of the pressed powder sheet 11, and the bottom of the scraper 123 is close to the lower surface of the pressed powder sheet 11. When the pressed powder head 1 is matched with the pressed powder machine 2, the scraper 123 protruding from the outer edge of the pressed powder sheet 11 can scrape off the powder left on the side wall of the pressed powder machine 2; the connecting section 122 is provided close to the pressed powder sheet 11. There are a first groove body 1221 and a second groove body 1222. The first groove body 1221 abuts against the upper side of the compressed powder sheet 11, and the lower side of the compressed powder sheet 11 abuts against the second groove body 122, so that the bracket 12 is snap-connected with the compressed powder sheet 11, and the stability of the connection is further improved. Since the cantilever section 121 of the bracket 12 needs to break up the fallen powder, after the connecting section 122 is fixed, the force of the cantilever section 121 can be enhanced, and the rigidity of the cantilever section 121 can be improved, thereby improving the service life of the bracket 12.

The first hole 211 is located above the powder pressing head 1. The first hole 211 corresponds to the powder pressing head 1. Powder falls from the first hole 211 above the powder pressing machine 2 into the bracket 12 above the powder pressing head 1. The bracket 12 breaks up the powder and evenly drops it onto the powder pressing sheet 11. The powder evenly falls under the powder pressing sheet 11 through the inclined surface for compaction. The scraper 123 abuts against the inner side of the powder cup 24 to scrape off the residual powder on the inner wall of the powder cup 24. The powder pressing shaft 22 can also move up and down to complete the compaction of the powder when the powder pressing head 1 is located at different depths of the powder cup 24.
