Description

Technical Field

[0001] The utility model belongs to the technical field of coffee capsule machines, and particularly relates to a coffee capsule machine with an arc-shaped powder pressing device. Background Art

[0002] Currently, there are some coffee capsule machines on the market that can grind coffee beans into coffee powder and make coffee capsules. They mainly include a bean grinding device and a powder pressing device. The bean grinding device can grind coffee beans into coffee powder. The ground coffee powder flows into the powder pressing channel on the powder pressing device through the powder discharge channel, and then flows into the capsule box below the powder pressing channel. The powder pressing device then moves downward along the powder pressing channel to compact the coffee powder in the capsule box. In the current coffee capsule machine, since the bean grinding device and the powder pressing device are arranged side by side in the machine body, the bean grinding tank of the bean grinding device is in the shape of a cone that contracts from top to bottom, and the powder pressing channel is arranged vertically downward, in order to prevent the bean grinding tank from interfering with the up and down movement path of the powder pressing device, a large horizontal distance needs to be set between the powder pressing channel and the bean grinding tank. This results in a corresponding increase in the volume of the entire coffee capsule machine and high packaging and transportation costs. Utility Model Content

DETAILED DESCRIPTION

[0036] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 4 As shown, this embodiment provides a coffee capsule machine with an arc-shaped powder pressing device, which is characterized by comprising:

[0038] Body 1;

[0039] a bean grinding device, disposed on the machine body 1, comprising a bean grinding tank 2 for adding coffee beans, a grinding assembly being installed at the bottom of the bean grinding tank 2 for grinding the coffee beans into coffee powder; and

[0040] The arc-shaped powder compacting device is arranged in the machine body 1 and is arranged in parallel with the bean grinding device. The arc-shaped powder compacting device includes an arc-shaped arc-shaped arc-shaped powder compacting channel 3 arranged from bottom to top, a powder hammer 4 arranged to slide up and down in the arc-shaped powder compacting channel 3, and a driving mechanism that drives the powder hammer 4 to slide up and down along the arc-shaped powder compacting channel 3. Specifically, when the powder compacting action is performed, the driving mechanism drives the powder hammer 4 to slide downward from the reset position on the upper side to the powder compacting position on the lower side along the arc-shaped powder compacting channel 3; when the powder compacting is completed, the driving mechanism drives the powder hammer 4 to slide upward from the powder compacting position to the reset position along the arc-shaped powder compacting channel 3.

[0041] The arc-shaped powder compacting channel 3 is fixedly arranged on a fixed seat in the machine body 1, and the arc-shaped powder compacting channel 3 includes a driving end, a transition section and a powder discharge end from top to bottom. The powder discharge end is located on the lower side of the bean grinding tank 2. The transition section bypasses the bean grinding tank 2 so that the driving end is not interfered with by the shape of the bean grinding tank 2. Specifically, when the driving mechanism drives the powder hammer 4 to slide up and down along the arc-shaped powder compacting channel 3, the bean grinding tank 2 will not interfere with the movement path of the powder hammer 4. The powder discharge end is provided with a powder outlet 32, which is used to dock with the capsule box.

[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, the arc-shaped powder pressing channel 3 is gradually arched upward from the left to right or from the right to the left in an arc shape from the front lower side of the bean grinding tank 2. The bean grinding tank 2 includes a cylindrical tank body at the top and a conical tank body located on the lower side of the cylindrical tank body and with a diameter gradually decreasing from top to bottom. The cylindrical tank body and the conical tank body are preferably integrally formed. In order to facilitate the capsule box to receive powder, the powder outlet is located at the front lower side of the conical tank body, and the transition section bypasses the conical tank body from the front side of the conical tank body from bottom to top and from right to left. Specifically, the powder outlet is set at the front lower side of the conical tank body, so that the lateral distance between the two is smaller, thereby making the internal structure layout of the machine body 1 more compact and the volume of the entire coffee capsule machine is further reduced. When the transition section bypasses the conical tank body, not only will the bean grinding tank 2 not interfere with the powder hammer 4, but the powder pressing stroke will also increase accordingly, which can meet the needs of powder pressing.

[0043] The above embodiment can also be configured such that the powder outlet is located below the front side of the conical tank body, and the transition section goes around the conical tank body from bottom to top and from left to right from the front side of the conical tank body.

[0044] In some embodiments, such as Figures 2 to 4 As shown, a mounting seat 33 is provided on the side wall of the arc-shaped powder pressing channel 3, and the driving mechanism is arranged on the mounting seat 33. A specific structure of the driving mechanism is that the driving mechanism includes a powder hammer motor 5 and a transmission assembly, and the transmission assembly includes a gear set and an arc-shaped rack 41. The output shaft of the powder hammer motor 5 is connected to the input end of the gear set, and the output end of the gear set is connected to the arc-shaped rack 41, specifically a meshing transmission. The arc-shaped rack 41 is slidably arranged in the arc-shaped powder pressing channel 3, and the lower end of the arc-shaped rack 41 is connected to the powder hammer 4. The arc-shaped rack 41 and the powder hammer 4 can be arranged as an integral molding, or the two can be fixedly connected. When the powder hammer motor 5 drives the gear set to rotate, the gear set meshes with the arc-shaped rack 41, driving the arc-shaped rack 41 and the powder hammer 4 to slide up and down to perform the powder pressing action or reset action.

[0045] The gear set includes a first gear 331 and a second gear 332 . The output shaft of the hammer motor 5 is connected to the first gear 331 , and the second gear 332 is meshed with both the first gear 331 and the arc-shaped rack 41 .

[0046] In some embodiments, Figures 2 to 4 As shown, to achieve a more compact layout within the machine body 1, the meshing teeth of the arcuate rack 41 are located inside the rack. This allows the mounting base 33 and the drive mechanism to be positioned within the inner space enclosed by the arcuate powder-pressing channel 3. To facilitate the meshing and transmission of the second gear 332 with the arcuate rack 41, a clearance groove 31 is provided on the sidewall of the arcuate powder-pressing channel 3. The second gear 332 passes through the clearance groove 31 and meshes with the arcuate rack 41.

[0047] In some embodiments, Figure 4 As shown, a sealing ring 6 is provided between the tamper 4 and the inner wall of the arcuate tamping channel 3. The sealing ring 6 provides a seal, preventing coffee powder from entering the machine body 1 through the arcuate tamping channel 3. The sidewall of the arcuate tamping channel 3 is also provided with an arcuate guide groove 34. The arcuate rack 41 is provided with a guide block 411. The guide block 411 is located within the arcuate guide groove 34, thereby limiting the upper and lower end positions of the arcuate rack 41.

[0048] In some specific embodiments, the bean grinding device also includes a grinding assembly arranged in the bean grinding tank 2, and the grinding assembly specifically includes a grinding knife and a grinding motor that drives the grinding knife to grind powder. A lower powder channel 21 is provided between the grinding assembly and the arc-shaped powder pressing channel 3. The coffee powder ground by the grinding assembly flows into the arc-shaped powder pressing channel 3 through the lower powder channel 21, and then falls into the capsule box at the lower end of the arc-shaped powder pressing channel 3. Thereafter, the driving mechanism can be directly started to drive the powder hammer 4 to press the coffee powder in the capsule box, so that the process continuity is better.

[0049] Working principle description:

[0050] The curved tamping channel 3 curves upward from the underside of the conical canister and then to the left, bypassing it. This avoids directly pressing against the canister vertically, further reducing the lateral distance between the curved tamping channel 3 and the canister, thereby reducing the overall size of the coffee capsule machine. During tamping, the tamper motor 5 drives the curved rack 41 downward via a gear train, which in turn drives the tamper 4 downward along the curved tamping channel 3 to tamp the powder.

[0051] The present invention is not limited to the above optional implementation methods. Under the premise of not conflicting with each other, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the scope of protection of the present invention.
