[0044] Embodiment 1

[0045] Refer Figures 1 to 7 As shown, this embodiment discloses a specific implementation manner of an automatic powder adding device for a coffee machine.

[0046] An automatic powder adding device for a coffee machine, refer Figures 1 to 7The system includes a housing, a door 1, a cup-carrying track 2, and a powder-discharging assembly 3 disposed on the door 1. The powder-discharging assembly 3 includes several powder-discharging units arranged side by side, preferably five. Each powder-discharging unit includes a powder box 31, a motor 32, a spiral extrusion rod disposed in the powder box 31, a right-angle bend 33, a first fixing member 34, an L-shaped moving plate 35, and a spring 36. The two ends of the right-angle bend 33 are respectively connected to the powder box 31 and the first fixing member 34. The first fixing member 34 is preferably a sheet metal part or a plastic part. The amount of powder dispensed is determined by the number of rotations of the motor 32, such as half a rotation, 1 / 4 rotation, etc., which allows for precise control of the powder dispensed amount. That is, the amount of powder dispensed is controlled by the rotation angle of the spiral extruder. A U-shaped sheet metal 37 is provided at the bottom of the powder box 31, and the spring 36 is positioned between the vertical portion 352 of the L-shaped moving plate 35 and the U-shaped sheet metal 37. The first fixing member 34 is provided with a first discharge port 341, and the outlet of the right-angle bend 33 is aligned with the first discharge port 341. The L-shaped moving plate 35 is slidably positioned on the... The bottom surface of the first fixing member 34, the L-shaped moving plate 35 is provided with the second material discharge port 351; the cup transport track 2 is provided with a cup holder assembly 21, the cup transport track 2 includes two parallel X-axis linear modules 23 and a Y-axis linear module 24 that travels along the X-axis linear modules 23, the cup holder assembly 21 moves along the Y-axis linear module 24, the cup holder assembly 21 is provided with a vertical push plate 22, specifically, the cup holder assembly 21 is provided with a coffee cup holder 211 and a vertical plate 212, the vertical push plate 22 is provided with Regarding the vertical plate 212, the highest point of the vertical push plate 22 is higher than the highest point of the coffee cup 4. The vertical push plate 22 pushes or moves away from the L-shaped moving plate 35. The advantage of this design is that when the vertical push plate 22 is close to the L-shaped moving plate 35, the coffee cup 4 will not interfere with the L-shaped moving plate 35. When the spring 36 is in the original position, the first discharge port 341 and the second discharge port 351 are staggered. The advantage of this staggered arrangement is that the L-shaped moving plate 35 blocks the first discharge port 341, stopping the discharge.

[0047] See Figures 2 to 6The working principle of the L-shaped moving plate 35 and the first fixing member 34 is as follows: First, the cup transport track 2 transports the coffee cup 4 to the L-shaped moving plate 35 aligned with any of the feeding units. The alignment standard is that the vertical push plate 22 is aligned with the L-shaped moving plate 35. Second, during the process of the Y-axis linear module 24 transporting the cup holder assembly 21 close to the L-shaped moving plate 35, the vertical push plate 22 pushes the L-shaped moving plate 35, causing the second feeding port 351 to move towards the first feeding port 341. When the second feeding port 351 is aligned with the first feeding port 341, the feeding channel is opened. Third... Step 1: Start the motor 32 and rotate the spiral extruder. The amount of powder dropped is determined by controlling the number of rotations of the motor 32. Step 4: Stop the motor 32. Step 5: During the process of the Y-axis linear module 24 transporting the cup holder assembly 21 away from the L-shaped moving plate 35, the vertical push plate 22 leaves the L-shaped moving plate 35, and the L-shaped moving plate 35 is bounced back by the spring 36, causing the second discharge port 351 to move away from the first discharge port 341. The second discharge port 351 and the first discharge port 341 return to their staggered positions, closing the discharge channel and preventing powder from falling when there is no coffee cup.

[0048] See Figures 2 to 6 , Figure 8To facilitate cleaning of the L-shaped moving plate 35, the first fixing member 34, and the right-angle bend 33, and to facilitate replacement of the powder box, a first sliding groove 342 and a second sliding groove 343 are respectively provided on both sides of the bottom of the first fixing member 34. The two edges of the horizontal part 353 of the L-shaped moving plate 35 respectively engage with the first sliding groove 342 and the second sliding groove 343, making installation and disassembly convenient. The output shaft 321 of the motor 32 is provided with several locking protrusions 322. The spiral extrusion rod and the output shaft 321 cooperate through the locking protrusions 322, which can realize the quick engagement of the powder box 31 and the output shaft 321 bracket, and disassembly is also convenient. The bottom of the powder box 31 is provided with several protrusions 311, and the top of the U-shaped sheet metal 37 is provided with holes 371 that cooperate with the protrusions 311. When installing the powder box 31, the bottom of the powder box 31 is quickly fixed by the cooperation of the protrusions 311 and the holes 371. The first discharge port 341 is round. The cylindrical shape of the first discharge port 341 is provided with an annular step 344 at its top; a second fixing member 312 is also fixed to the bottom surface of the powder box 31, preferably a bent sheet metal part, the second fixing member 312 extends from the bottom of the powder box 31 and is provided with an annular notch 313, the outlet of the right-angle bend 33 passes through the annular notch 313 and abuts against the annular step 344; an annular protrusion 345 is provided above the annular step 344. The radius of the annular defect 313 is larger than the radius of the annular protrusion 345. An arc-shaped groove 346 is provided on the side of the annular protrusion 345. The arc-shaped groove 346 and the annular defect 313 engage with each other, that is, the edge of the annular defect 313 engages with the arc-shaped groove 346. When the arc-shaped groove 346 engages with the annular defect 313, the protrusion 311 and the hole 371 are perfectly matched, and the spiral extrusion rod and the output shaft 321 are matched by the locking protrusion 322.

[0049] When it is necessary to disassemble the L-shaped movable plate 35 and the first fixing member 34, simply grasp the first fixing member 34 and pull it away from the powder box 31. Since the radius of the annular defect 313 is larger than the radius of the annular protrusion 345, the annular protrusion 345 can move within the range of the annular defect 313. After the annular protrusion 345 moves, the edge of the arc groove 346 and the annular defect 313 disengages, allowing for quick disassembly of the L-shaped movable plate 35 and the first fixing member 34. During installation, simply align the arc groove 346 with the annular defect 313. Installation and disassembly are convenient, facilitating cleaning and maintenance. When the powder box 31 needs to be replaced, first quickly remove the L-shaped moving plate 35 and the first fixing part 34, then hold the bottom of the powder box 31 and lift it upwards to disengage the protrusion 311 and the hole 371. Then pull the powder box 31 out in the direction away from the output shaft 321. The disassembly and installation of the powder box 31 are also convenient. After the powder box 31 is properly installed, it is limited by the simultaneous engagement of three positions: the engagement of the output shaft 321 and the spiral extrusion rod, the engagement of the protrusion 311 and the hole 371, and the engagement of the arc groove 346 and the annular defect 313, so that the powder box 31 is installed stably.

[0050] Due to differences in the physical properties of powders, some powders are characterized by high viscosity and poor flowability, meaning that the friction between particles is relatively large; these powders are defined as high-viscosity powders. Conversely, some powders are characterized by low viscosity and good flowability, meaning that the friction between particles is relatively small, such as granulated sugar; these powders are defined as low-viscosity powders. The powder dispensing unit is equipped with either high-viscosity or low-viscosity powder. The powder dispensing unit equipped with high-viscosity powder uses a first motor; the powder dispensing unit equipped with low-viscosity powder uses a second motor. The power of the first motor is greater than that of the second motor. That is, a high-power first motor drives the powder dispensing unit equipped with high-viscosity powder, while a low-power second motor drives the powder dispensing unit equipped with low-viscosity powder. This approach helps to determine the appropriate motor power based on the viscosity of the powder, and also helps to reduce costs by using a lower-power motor.
