[0001] The invention relates to the technical field of commercial beverage machines, in particular to a solid particle feeding device for a beverage machine and a beverage machine. Background Art

[0002] At present, the production of fresh milk drinks, yogurt drinks, NFC juice drinks, etc. on the market requires equipment and manual cooperation. In order to provide drinks with a variety of flavors, solid particles such as fruit particles, oats, nuts, beans, etc. are often added to these drinks manually. Especially when the maximum diameter of the solid particles reaches 25mm, there is no dedicated beverage machine that can automatically add large-diameter solid particles and mix a variety of drinks.

[0003] In view of this, it is necessary to develop an automated beverage machine that can automatically add solid particles such as fruit particles, oats, nuts, beans, etc. on demand. The maximum diameter of the solid particles can reach 25mm. Because these solid particles have a certain size and the sizes vary, how to intermittently add these solid particles to the beverage without causing jamming of adding due to factors such as bridging between solid particles is a technical problem that needs to be solved urgently. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to disclose a solid particle feeding device for a beverage machine and a beverage machine, which can realize the feeding of solid particles without jamming by feeding solid particles in a reciprocating screw feeding assembly.

[0005] The first object of the present invention is to design a solid particle feeding device for a beverage machine.

[0006] The second object of the present invention is to design a beverage machine.

[0007] To achieve the above-mentioned first invention purpose, the present invention provides a solid particle feeding device for a beverage machine, comprising a driving motor, a shell, an inlet, an outlet, and a screw feeding assembly, wherein the driving motor drives the screw feeding assembly through a coupling, and the screw feeding assembly is arranged in the shell, the inlet is arranged on the upper side of the shell, and the outlet is arranged on the lower side of the shell, the screw feeding assembly comprises a reciprocating screw, a reciprocating screw nut and a moving block, the reciprocating screw nut is engaged with the reciprocating screw, the moving block is sleeved on the reciprocating screw and fixedly connected with the reciprocating screw nut, the contact surface of the moving block and the solid particles is an inclined surface, and the inlet and the outlet correspond to different positions of the reciprocating screw.

[0008] Preferably, the angle between the inclined surface of the moving block and the horizontal plane is 30 degrees to 60 degrees.

[0009] Preferably, the reciprocating screw nut is fixed in the moving block via a fixing block.

[0010] Preferably, the inclined surface of the moving block is located below the feed inlet.

[0011] Preferably, the moving distance of the moving block is 10 mm-50 mm.

[0012] Preferably, it also includes a material baffle plate, which is arranged on the side of the material inlet.

[0013] Preferably, an arc-shaped notch is provided at the bottom of the baffle plate.

[0014] Preferably, the vertical distance between the baffle plate and the reciprocating screw rod is 5 mm-25 mm.

[0015] Preferably, a storage bin is provided above the feed inlet, a cover is provided on the top of the storage bin, and the storage bin is made of a transparent material or is provided with a transparent window.

[0017] Compared with the prior art, the technical effects of the present invention are as follows:

The solid particles will not continue to automatically fall into the outlet. Through the setting of the moving block of the screw feed assembly, the solid particles can be physically pushed into the outlet through the moving block.

[0019] (2) By setting the relative distance between the inlet and the outlet, the solid particles will not be discharged directly through the outlet, but will be pushed out by the moving block. Since the moving distance of the moving block is relatively stable each time, the discharge amount of the solid particles is also relatively stable, thus achieving automatic and controllable solid particle discharge.

[0020] (3) The reciprocating movement of the moving block also avoids the particle jamming caused by bridging between solid particles, making the leakage amount accurate and without jamming. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1

[0031] Ginseng Figure 1 As shown, this embodiment discloses a specific implementation of a solid particle feeding device for a beverage machine (hereinafter referred to as "feeding device").

[0032] Beverage machine solid particle feeding device, reference Figure 1 As shown, it includes a driving motor 3, a shell 1, an inlet 2, an outlet 8, and a screw feeding assembly. The driving motor 3 drives the screw feeding assembly through a coupling 5. The screw feeding assembly is arranged in the shell 1, the inlet 2 is arranged on the upper side of the shell 1, and the outlet 8 is arranged on the lower side of the shell 1. The screw feeding assembly includes a reciprocating screw 6, a reciprocating screw nut 72 and a moving block 7. The reciprocating screw nut 72 is engaged with the reciprocating screw 6, and the moving block 7 is sleeved on the reciprocating screw 6 and fixedly connected to the reciprocating screw nut 72. The reciprocating screw nut 72 is fixed in the moving block 7 by a fixing block 73, that is, after the reciprocating screw nut 72 is installed in the moving block 7, the fixing block 73 is fixed to the moving block 7 and the reciprocating screw nut 72 by a screw 74 to make them a whole. The moving block 7 The contact surface with the solid particles is an inclined surface 71, and the feed port 2 and the discharge port 8 correspond to different positions of the reciprocating screw 6. Specifically, the feed device is used to feed fixed particles of a certain size, such as fruit particles, oats, nuts, beans and other solid particles of 5mm-25mm, and can preferably adapt to solid particles of 5mm, 10mm, and 25mm. Because solid particles of different sizes and shapes have different angles of repose, there will also be bridging phenomena between different solid particles. Therefore, the feed port 2 and the discharge port 8 of the feed device have a certain distance in the horizontal direction. This distance can ensure that the solid particles automatically stop leaking due to their own angle of repose and bridging phenomenon, that is, to ensure that the solid particles will not leak directly from the discharge port 8; in order to achieve precise leakage according to quantity, the reciprocating screw 6 is driven by the drive motor 3, so that the reciprocating screw thread 61 The reciprocating screw nut 72 is driven to drive the moving block 7 to reciprocate at the same time. When the moving block 7 moves toward the discharge port 8, the accumulated solid particles are pushed into the discharge port 8 to achieve leakage. When the moving block 7 moves away from the discharge port 8, the solid particles stop leaking due to the distance of the repose angle and the bridging phenomenon. Accurate leakage is achieved through the reciprocating motion of the moving block 7. In this embodiment, the moving distance of the moving block 7 is 10mm-50mm. The moving distance affects the leakage amount of the moving block 7 during a single movement. The smaller the moving distance, the less the single leakage amount and the higher the leakage accuracy. According to the size of the solid particles and actual needs, the optimal moving distance can be 10mm, 20mm, 30mm, 40mm, or 50mm.

[0033] It should be further explained that in order to reduce the obstruction of the flow of solid particles by the moving block 7 during the reciprocating motion, the area below the moving block 7 and the feed port 2 is designed as a slope 71, and the angle between the slope 71 and the horizontal plane is 30 degrees to 60 degrees, preferably 45 degrees.

[0034] It should be further explained that, in order to store a certain amount of solid particles and observe the remaining solid particles at any time so that the beverage machine can make beverages at any time, a storage bin 21 is arranged above the feed port 2, and a cover body 22 is arranged on the top of the storage bin 21. The size of the storage bin 21 is determined according to the demand for fixed particles, and the shape is cylindrical. Of course, other shapes are also possible, such as a rectangle. In order to facilitate the observation of the remaining solid particles at any time, the storage bin 21 is designed to be a transparent material, or a transparent window 23 is provided on one side of the storage bin 21.

[0035] It should be further explained that after adding a certain amount, the drive motor 3 is stopped by a control signal, so that the moving block 7 stops pushing the material back and forth. When the next cup of drink is ready, the drive motor 3 is rotated by a control signal, thereby driving the screw feeding assembly to push the solid particles. The drive motor 3 transmits the rotational force to the reciprocating screw 6 through the power output mechanism 4 and the coupling 5. The power output mechanism 4 can be gear meshing or directly driven by a motor. Since the power output mechanism 4 directly adopts the existing technology and is not the focus of this application, it is not further explained here, and those skilled in the art can achieve it without creative work.

[0036] Through this embodiment, the technical effects are as follows: (1) After solid particles of a certain size enter through the feed port, they accumulate in the shell. On the one hand, due to the existence of the repose angle of the solid particles, and on the other hand, there is a bridging phenomenon between the solid particles. The solid particles do not continue to automatically fall into the discharge port. By setting the moving block of the screw feed assembly, the solid particles can be physically pushed into the discharge port through the moving block. The greater the moving distance of the moving block, the more solid particles are pushed in.

[0037] (2) By setting the relative distance between the inlet and the outlet, the solid particles will not be discharged directly through the outlet, but will be pushed out by the moving block. Since the moving distance of the moving block is relatively stable each time, the discharge amount of the solid particles is also relatively stable, thus achieving automatic and controllable solid particle discharge.

[0038] (3) The reciprocating movement of the moving block also avoids the particle jamming caused by bridging between solid particles, making the leakage amount accurate and without jamming.

[0039] Example 2

[0040] Ginseng Figure 2As shown, this embodiment discloses a specific implementation of a solid particle feeding device for a beverage machine (hereinafter referred to as "feeding device").

[0041] The difference from Example 1 is that the design scheme that relies solely on the repose angle of solid particles and the bridging phenomenon to prevent leakage directly from the discharge port 8 requires that the feed port 2 and the discharge port 8 maintain a considerable distance in the horizontal direction. Therefore, the technical scheme of Example 1 will cause the size of the feed device in the horizontal direction to be larger. Therefore, in order to shorten the size of the feed device in the horizontal direction, Example 2 refers to Figure 2 As shown, on the basis of Example 1, the feeding device of Example 2 also includes a baffle plate 9, which is arranged on the side of the feeding port 2, that is, after the solid particles enter from the feeding port 2, they are clamped between the inclined surface 71 of the moving block 7 and the baffle plate 9, and the baffle plate 9 changes the repose angle of the solid particles, so that the solid particles are caught by the baffle plate 9 in advance in a natural state. The advantage of such a design is that the horizontal distance between the feeding port 2 and the discharging port 8 can be shortened, the size of the feeding device in the horizontal direction is reduced, and the overall size of the beverage machine is reduced; in addition, the vertical distance between the bottom of the baffle plate 9 and the top of the reciprocating screw rod 6 is 5mm-25mm, and this vertical The size of the vertical distance depends on the size of the solid particles. For example, when the maximum size of the solid particles is 25 mm, the vertical distance can be set to 25 mm to reduce jamming factors such as bridging and make the material leakage smooth. For example, when the maximum size of the solid particles is 10 mm, the vertical distance can be set to 10 mm to reduce jamming factors such as bridging and make the material leakage smooth. Another advantage of this design is that by replacing baffle plates of different sizes, the feeding device can adapt to solid particles of corresponding sizes. In order to reduce the friction and jamming of solid particles sandwiched between the baffle plate 9 and the reciprocating screw 6, an arc-shaped notch 91 is set at the bottom of the baffle plate 9, and the arc-shaped notch 91 can be semicircular.

[0042] Through Example 2, on the one hand, the baffle plate 9 changes the repose angle of the solid particles, so that the space for the solid particles to naturally leak down becomes smaller, thereby shortening the horizontal distance between the inlet 2 and the outlet 8, and further reducing the size of the feeding device in the length direction, which helps to miniaturize the feeding device; on the other hand, the baffle plate 9 is replaceable, and the baffle plate 9 is fixed to the inner wall of the shell 1 by screws. By replacing baffle plates of different sizes, the feeding device can adapt to solid particles of different sizes, thereby improving the adaptability of the feeding device to the size of solid particles.
