Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coffee extraction technology, specifically relating to a spiral feeding assembly structure for a coffee extraction machine. Background Technology
[0002] A coffee extraction machine is a device for processing coffee. Coffee beans are fed into the extraction unit, and the extraction unit squeezes the coffee beans to extract the original liquid. It is a commonly used processing device for coffee. When conveying coffee beans, a professional conveying screw feeder is generally used for transmission and conveying, which facilitates the subsequent processing of coffee beans by the internal components of the equipment.
[0003] Modern coffee extractors primarily use an internal screw feeder to deliver coffee beans. However, this method has certain drawbacks in practical use. Specifically, after the screw feeder delivers the coffee beans, they steadily enter the extraction unit. However, the extraction unit produces a certain amount of residue after extraction, which accumulates inside the unit and cannot be easily and efficiently removed. Operators must manually disassemble the extraction unit's casing to remove the residue. This step affects the coffee extractor's efficiency and overall performance. Utility Model Content

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.
[0025] Depend on Figure 1 and Figure 2 As shown, it is a schematic diagram of the spiral feeding assembly structure of the coffee extractor in this embodiment. The spiral feeding assembly structure of the coffee extractor includes a mounting bracket 1, a dispersing cylinder 2 and a feeding pump 3. The mounting bracket 1 is installed inside the coffee extractor. The dispersing cylinder 2 is installed on the mounting bracket 1. The feeding pump 3 is installed on the upper surface of the dispersing cylinder 2. The feeding mechanism 5 is installed on the mounting bracket 1.
[0026] The coffee raw material to be processed is fed into the dispersing cylinder 2 by the operation of the feeding pump 3. Then the coffee raw material enters the feeding mechanism 5. At this time, the feeding mechanism 5 provides stable delivery of the coffee raw material, allowing it to enter the extraction component 4. This facilitates the subsequent extraction process of the coffee raw material by the extraction component 4, thus achieving stable processing of the coffee raw material.
[0027] From the appendix Figure 3 As shown, this is a schematic diagram of the feeding mechanism 5 in this embodiment. The feeding mechanism 5 includes a movable frame 51, an outer cylinder 52, a screw feeder 53, a discharge pipe 54, a drive motor 55, a sliding assembly 56, and a push-out plate 57. The movable frame 51 is installed inside the mounting bracket 1. The drive motor 55, which controls the movement of the movable frame 51, is installed on the inner wall of the mounting bracket 1. The push-out plate 57 is installed at the end of the movable frame 51. The push-out plate 57 pushes out the residue in the extraction assembly 4 inside the coffee extractor. The outer cylinder 52 is installed inside the movable frame 51. The screw feeder 53 is rotatably installed inside the outer cylinder 52. The discharge pipe 54 is installed on one side of the outer wall of the outer cylinder 52. The drive motor 55 is installed on the side of the movable frame 51. The output end of the drive motor 55 is connected to the screw feeder 53.
[0028] When the raw material enters the outer cylinder 52, the drive motor 55 and the sliding component 56 operate. At this time, the sliding component 56 can control the overall position of the moving frame 51. The entire feeding mechanism 5 slides along the length of the mounting bracket 1 until the discharge pipe 54 at the end of the outer cylinder 52 is aligned with the receiving slot in the extraction component 4. When the drive motor 55 runs, the screw feeder 53 rotates stably inside the outer cylinder 52. At this time, using the structure and shape of the screw feeder 53 itself, the screw feeder 53 stably conveys the coffee raw material inside the outer cylinder 52. The raw material is then directly discharged through the discharge pipe 54, allowing the raw material to enter the extraction component 4.
[0029] When the extraction component 4 extracts the raw material, the moving frame 51 is reset as a whole. After the extraction component 4 finishes processing the raw material, the cylinder in the extraction component 4 pushes out the raw material residue in the extraction component 4. At this time, the sliding component 56 will drive the moving frame 51 to move as a whole. At this time, the push-out plate 57 at the end of the moving frame 51 pushes out the residue discharged from the extraction component 4, realizing the automatic push-out of the residue.
[0030] From the appendix Figure 4As shown, this is a structural schematic diagram of the sliding component 56 in this embodiment. The sliding component 56 includes a slide rail 561, a slider 562, and a linear guide rail 563. The slide rail 561 is installed on one side of the inner wall of the mounting bracket 1. The slider 562 is slidably installed on the outside of the slider 562. The slider 562 is connected to the side wall of the movable frame 51. The linear guide rail 563 is installed on the inner wall of the mounting bracket 1 away from the slide rail 561. The linear guide rail 563 is connected to the side wall of the movable frame 51.
[0031] During use, the linear guide rail 563 drives the moving frame 51 to slide as a whole, so as to realize the purpose of changing and adjusting the position of the moving frame 51, so that the push plate 57 at the end of the moving frame 51 can push the residue and the raw material discharged from the discharge pipe 54 into the extraction component 4.
[0032] From the appendix Figure 5 As shown, this is a schematic diagram of the stirring mechanism 6 in this embodiment. The stirring mechanism 6 includes a dispersing motor 61, a dispersing shaft 62, a dispersing component 63, and a dispersing blade 64. The dispersing motor 61 is installed on the upper surface of the dispersing cylinder 2. The output end of the dispersing motor 61 passes through the dispersing cylinder 2. The dispersing shaft 62 is installed at the end of the output end of the dispersing motor 61. The dispersing shaft 62 rotates inside the dispersing cylinder 2. The dispersing component 63 is installed outside the dispersing shaft 62. The dispersing blade 64 is installed outside the dispersing shaft 62 and below the dispersing component 63. The bottom end of the dispersing cylinder 2 is conical. The dispersing blade 64 is slidably connected to the inner wall of the dispersing cylinder 2.
[0033] The feed pump 3 conveys the coffee raw material, which then enters the dispersing cylinder 2. The coffee raw material slides along the inner wall of the dispersing cylinder 2 and enters the outer cylinder 52 stably. Meanwhile, the operation of the dispersing motor 61 drives the dispersing shaft 62 to drive the dispersing component 63 and the dispersing blade 64 to rotate stably inside the dispersing cylinder 2, preventing the coffee raw material from clogging inside the dispersing cylinder 2 and ensuring a stable output of the coffee raw material.
[0034] From the appendix Figure 2 As shown, the feed pump 3 has a connection port installed on its side. The connection port conveys coffee raw materials through the installation pipe. The end of the feed pump 3 is connected to the dispersing cylinder 2. The bottom end of the dispersing cylinder 2 has a discharge port, which is connected to the inside of the outer cylinder 52. The connection port on the side of the feed pump 3 facilitates the connection of the external pipe to the connection port. Under the operation of the feed pump 3, the raw materials in the pipe are drawn out, so that the raw materials enter the dispersing cylinder 2 stably. The installation and operation of the stirring mechanism 6 inside the dispersing cylinder 2 ensures that the raw materials enter the outer cylinder 52 stably, thus achieving stable delivery of raw materials.
[0035] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
