Description

Technical Field

[0001] This utility model belongs to the field of coffee processing technology, specifically relating to a coffee grounds recycling device. Background Technology

[0002] Coffee is a beverage made from roasted and ground coffee beans. It has many effects on the human body, including diuresis, stimulation of the central nervous and respiratory systems, dilation of blood vessels, acceleration of heartbeat, strengthening of skeletal muscles, and relief of brain and muscle fatigue. As a result, more and more manufacturers are joining the coffee production industry. Furthermore, with the improvement of people's living standards, drinking coffee has gradually become a daily habit. Whether in coffee production or brewing, coffee beans generally need to be extracted, and there are many extraction methods, such as cold brew, flash brew, and golden cup brewing. During the flash brewing process, a lot of coffee grounds are usually left. In addition to discarding these coffee grounds directly, people also use corresponding recycling devices to recycle and reuse them, thereby improving the utilization of coffee.

[0003] According to CN216941932U, a flash coffee grounds recycling device is disclosed. This technology discloses that "the flash coffee grounds recycling device includes a gantry frame; a workbench fixedly installed inside the gantry frame; a discharge seat fixedly installed inside the gantry frame; a pressing barrel fixedly installed on top of the workbench; and a pressure plate positioned above the pressing barrel, the pressure plate being adapted to the pressing barrel, etc. This device has the technical effect of squeezing coffee grounds with the pressure plate to remove most of the excess water, thereby reducing the moisture content of the coffee grounds. The squeezed and dehydrated coffee grounds can then be dried, greatly improving drying efficiency. Furthermore, the waste liquid ring tank and waste liquid conduit can collect coffee grounds waste liquid that still has some utilization value, further improving waste utilization rate."

[0004] While the above design can squeeze the coffee grounds to remove excess water and reduce the moisture content, thus improving the efficiency of drying the coffee grounds later, the device lacks a stirring mechanism. During the repeated squeezing and expelling of water from the coffee grounds, some water is carried away and trapped between the coffee grounds, preventing some water from passing through smoothly. This affects the water extraction effect and reduces the effectiveness of the device.

[0005] To address the aforementioned problems, this application proposes a coffee grounds recycling device. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides a coffee grounds recycling device that effectively prevents moisture from remaining in the coffee grounds, allowing some moisture to pass through smoothly, thus improving the device's performance and meeting practical application requirements.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a coffee grounds recycling device, including a support frame and a pressing barrel body fixed by a placement plate and a unloading mechanism installed below the pressing barrel body, wherein a pressing mechanism is provided above the pressing barrel body;

[0008] A stirring assembly is installed on the support frame. The stirring assembly includes a movable plate slidably connected to the surface of the support frame, an electric push rod fixed to the surface of the movable plate by a U-shaped frame, and a drive motor disposed at the output end of the electric push rod. A stirring blade is fixed at the output end of the drive motor.

[0009] As a preferred embodiment of the coffee grounds recycling device of this utility model, the output end of the electric push rod is fixed with a fixing rod, and the bottom end of the fixing plate is fixed with a base plate. The drive motor is fixed on the surface of the base plate, and a protective cover is provided on the outside of the drive motor. The protective cover is fixed on the surface of the base plate and is rotatably connected to the stirring blade through a bearing.

The surface of the limiting rod is provided with a moving groove adapted to the limiting rod. The moving plate and the limiting rod are slidably connected through the moving groove. A fixing block is fixed on the top of the support frame. A pull rod is slidably connected inside the fixing block. A spring is wound around the surface of the pull rod. The two ends of the spring are fixedly connected to the fixing block and the pull rod, respectively. The surface of the moving plate is provided with slot one and slot two adapted to the pull rod.

[0011] As a preferred embodiment of the coffee grounds recycling device of this utility model, one end of the pull rod is designed with a tapered structure.

[0012] As a preferred embodiment of the coffee grounds recycling device of this utility model, the outside of the stirring blade is provided with a splash guard, and a symmetrically arranged support tube is fixed between the splash guard and the moving plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1 As shown:

[0026] A coffee grounds recycling device includes a support frame 1, a pressing barrel body 2 fixed by a placement plate, and a discharge mechanism 3 installed below the pressing barrel body 2. A pressing mechanism 4 is provided above the pressing barrel body 2.

[0027] In this implementation plan: The existing device {Publication (Announcement) No.} CN216941932U discloses a flash coffee grounds recycling device. The coffee grounds recycling device proposed in this application uses the same technical means in the unloading mechanism 3 and the extrusion mechanism 4 as in the prior art. These technical means will not be described in detail here. This application further improves the existing main body. For details, please refer to the disclosed technology below. In order to solve the technical problems existing in the prior art, such as the background technology disclosed above, "the above design can extrude coffee grounds during use, and the coffee grounds..." Excess water is squeezed out, thereby reducing the moisture content in the coffee grounds and improving the efficiency of subsequent drying. However, this device does not have a stirring mechanism. During the repeated squeezing and expelling of water from the coffee grounds, some water is carried away and trapped between the coffee grounds, preventing some water from passing through smoothly. This affects the water extraction effect and reduces the effectiveness of the device. In terms of usage, this problem is obviously a real and difficult problem to solve. Therefore, to solve this technical problem, a stirring component 5 and a cleaning component 6 have been added to this application. All electrical equipment involved in this product is powered by an external power source.

[0028] It should be noted that the components used in the unloading mechanism 3 and the extrusion mechanism 4 have been disclosed in publication number CN216941932U, and their performance can be referred to publication number CN216941932U (i.e., the "unloading seat, discharge port, support plate, cylinder, connecting rod, waste liquid ring groove, annular filter screen, waste liquid conduit and passageway components" disclosed in this prior art).

[0029] Furthermore:

[0030] like Figures 1-5 As shown:

[0031] A stirring assembly 5 is installed on the support frame 1. The stirring assembly 5 includes a movable plate 501 slidably connected to the surface of the support frame 1, an electric push rod 503 fixed to the surface of the movable plate 501 by a U-shaped frame, and a drive motor 504 disposed at the output end of the electric push rod 503. A stirring blade 505 is fixed at the output end of the drive motor 504.

[0032] In this implementation plan: When using the coffee grounds recycling device, coffee grounds are first placed inside the extrusion barrel body 2, and then extruded by the unloading mechanism 3. The grounds are discharged through the drain port on the extrusion barrel body 2. After extrusion, the extrusion barrel body 2 is reset, and then the moving plate 501 is moved. Then the drive motor 504 is started, which drives the stirring blade 505 to rotate. At the same time, the electric push rod 503 is started, which drives the stirring blade 505 to move down synchronously to stir and loosen the compressed coffee grounds. After stirring, the extrusion mechanism 4 extrudes again, which effectively prevents moisture from being trapped in the coffee grounds and allows some moisture to pass through smoothly, improving the device's performance and meeting actual usage requirements. Through repeated compression and stirring, the coffee grounds are then discharged by the unloading mechanism 3 for subsequent drying.

[0033] Furthermore;

[0034] In an optional embodiment, the output end of the electric push rod 503 is fixed with a fixed rod, and the bottom end of the fixed plate is fixed with a base plate. The drive motor 504 is fixed on the surface of the base plate, and a protective cover 506 is provided on the outside of the drive motor 504. The protective cover 506 is fixed on the surface of the base plate and is rotatably connected to the stirring blade 505 through a bearing.

[0035] In this embodiment, the protective cover 506 can protect the drive motor 504, preventing coffee grounds from affecting the operation of the drive motor 504, thereby improving the service life of the drive motor 504.

[0036] Furthermore;

[0037] In an optional embodiment, the top of the support frame 1 is provided with a rectangular groove, and two sets of symmetrically arranged limiting rods 502 are provided in the rectangular groove. The surface of the limiting rod 502 is provided with a moving groove adapted to the limiting rod 502. The moving plate 501 and the limiting rod 502 are slidably connected through the moving groove. The top of the support frame 1 is fixed with a fixing block 508. A pull rod 509 is slidably connected inside the fixing block 508. A spring 511 is wound around the surface of the pull rod 509. The two ends of the spring 511 are fixedly connected to the fixing block 508 and the pull rod 509 respectively. The surface of the moving plate 501 is provided with a slot 1 512 and a slot 2 513 adapted to the pull rod 509 respectively.

[0038] In this embodiment: the pull rod 509 is then pulled, which in turn stretches the spring 511 until the pull rod 509 moves out of the moving plate 501. Then the moving plate 501 is pushed to slide on the surface of the limiting rod 502. When the slot 513 on the moving plate 501 corresponds to the pull rod 509, the pull rod 509 is then released, so that the pull rod 509 is inserted into the slot 513, thereby locking the position of the moving plate 501.

[0039] Furthermore;

[0040] In an alternative embodiment, one end of the pull rod 509 is designed with a tapered structure.

[0041] In this embodiment, one end of the pull rod 509 is designed with a tapered structure, which makes the end diameter smaller, thereby allowing it to be better inserted into the interior of the slot 2 513 and improving the performance of this structure.

[0042] Furthermore;

[0043] In an optional embodiment, a splash guard 507 is provided on the outside of the stirring blade 505, and symmetrically arranged support tubes 514 are fixed between the splash guard 507 and the moving plate 501.

[0044] In this embodiment, the splash guard 507 corresponds to the main body 2 of the extrusion barrel, thereby preventing coffee grounds from splashing during the stirring process.

[0045] Furthermore;

[0046] The coffee grounds recycling device has a cleaning component 6 installed on the upper surface of the moving plate 501. The cleaning component 6 includes an air pump 601 fixed on the upper surface of the moving plate 501, a delivery pipe 602 fixed at the output end of the air pump 601, and a connecting pipe 603 fixed at the bottom end of the delivery pipe 602. The two ends of the connecting pipe 603 are fixed between two sets of support pipes 514.

[0047] In this implementation scheme: by activating the air pump 601, the gas generated by the air pump 601 is discharged into the conveying pipe 602, and then through the conveying pipe 602 to the connecting pipe 603, so that the gas in the connecting pipe 603 is discharged through the support pipe 514. This can clean the coffee grounds residue attached to the surface of the stirring blade 505, thereby preventing the coffee grounds from being carried out from the inside of the extrusion barrel body 2, thus further improving the use effect of the equipment and making the device more flexible and practical.

[0048] The working principle and usage process of this utility model are as follows: When using this coffee grounds recycling device, coffee grounds are first placed inside the extrusion barrel body 2, then extruded by the unloading mechanism 3 and discharged through the drain port on the extrusion barrel body 2. After extrusion, the extrusion barrel body 2 resets. Then, the pull rod 509 is pulled, simultaneously stretching the spring 511 until the pull rod 509 moves out of the moving plate 501. The moving plate 501 is then pushed to slide on the surface of the limiting rod 502. When the slot on the moving plate 501... When slot 513 aligns with lever 509, lever 509 is released, allowing it to insert into slot 513. Because one end of lever 509 has a tapered design, its smaller diameter facilitates better insertion into slot 513, improving the usability of the design. Then, drive motor 504 is activated, rotating the stirring blade 505. Simultaneously, electric push rod 503 moves the stirring blade 505 downwards to loosen and agitate the compressed coffee grounds. During this process, splash guard 507 and... The extrusion barrel body 2 corresponds to the coffee grounds, thus preventing splashing during the stirring process. Simultaneously, the protective cover 506 protects the drive motor 504, preventing coffee grounds from affecting its operation and extending its lifespan. After stirring, the extrusion mechanism 4 further compresses the coffee grounds, effectively preventing moisture from remaining inside and allowing some moisture to pass through smoothly, improving the device's performance and meeting practical needs. During the upward movement of the stirring blade 505, the air pump 601 is activated, discharging the generated gas into the conveying pipe 602 and then into the connecting pipe 603. The gas in the connecting pipe 603 is then discharged through the support pipe 514, cleaning any coffee grounds residue adhering to the surface of the stirring blade 505 and preventing coffee grounds from being carried out of the extrusion barrel body 2, further improving the device's performance and making it more flexible and practical. Through repeated compression and stirring, the coffee grounds are then discharged through the unloading mechanism 3 for subsequent drying.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
