Description

Technical Field

[0001] This utility model relates to the field of coffee bean processing technology, specifically to an automatic coffee bean peeling device. Background Technology

[0002] Coffee beans refer to the fruit of the plant used to make coffee. Broadly speaking, there are two types of coffee beans in the world: Arabica and Robusta. The coffee fruit consists of two oval seeds facing each other. The side where they meet is flat and called a flat bean, but some beans consist of a single round seed and are called round beans; their taste is identical. Currently, during coffee bean processing, the outer skin needs to be removed. Existing technology typically uses a single peeling roller for this purpose. This method is not very effective at removing the skin, and after peeling, manual removal of the beans from the roller is required, which is time-consuming, reduces processing efficiency, and increases the workload.

[0003] To address the aforementioned issues, a utility model patent with authorization announcement number CN221532776U discloses a coffee bean peeling device. This device not only performs multiple peeling processes on coffee beans to improve processing efficiency, but also automatically conveys and discharges the peeled coffee beans, thereby increasing work efficiency and reducing the workload of workers.

[0004] However, in actual use, the peeling process is usually carried out on freshly picked fruits, whose peels have a high water content and relatively large weight. Using a blower to separate the peels is not very effective, resulting in peels remaining in the coffee beans, which cannot meet the usage requirements. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic coffee bean peeling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic coffee bean peeling device includes: a peeling tank with a lid at one end, a feed hopper at the upper end of the peeling tank, a discharge pipe at the lower right side of the peeling tank, a screening frame below the discharge pipe, and a sieve frame slidably mounted on the screening frame; a peeling mechanism installed inside the peeling tank for peeling the coffee beans; a connecting mechanism located between the sieve frame and the screening frame for slidably mounting the sieve frame on the screening frame; and a driving mechanism installed on the screening frame for driving the movement of the sieve frame.

[0008] As a preferred embodiment, the peeling mechanism includes a peeling rotating shaft rotatably installed inside the peeling tank, a spiral peeling paddle mounted on the peeling rotating shaft, and a peeling motor mounted on the right side of the peeling tank. The output end of the peeling motor is drivenly connected to the shaft end of the peeling rotating shaft.

[0009] As a preferred embodiment, a peeling rotating sleeve is rotatably mounted on the can lid, a second spiral peeling paddle is mounted on the peeling rotating sleeve, and a second peeling motor is also mounted on the can lid. The output end of the second peeling motor is drivenly connected to the shaft end of the peeling rotating sleeve.

[0010] As a preferred embodiment, the end of the peeling rotating shaft further extends into a peeling connecting shaft, which is rotatably inserted into the peeling rotating sleeve.

[0011] As a preferred embodiment, the spiral peeling propeller one and the spiral peeling propeller two have opposite spiral directions.

[0012] As a preferred embodiment, the connecting mechanism includes a connecting groove on the screening frame, a connecting column installed in the connecting groove, a connecting slider slidably mounted on the connecting column, and the connecting slider being fixedly connected to the screen frame.

[0013] As a preferred embodiment, the sieve frame is inclined.

[0014] As a preferred embodiment, the driving mechanism includes a driving frame mounted on a screening rack, a driving shaft rotatably mounted inside the driving frame, a driving cam mounted on the driving shaft, the driving cam abutting against the screen frame, and a driving motor mounted on the driving frame, the output end of the driving motor being drivenly connected to the driving shaft.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: The drive motor drives the drive shaft to rotate, which in turn drives the drive cam to rotate. The drive cam then pushes the sieve frame to move, thereby vibrating the sieve frame and screening the coffee beans inside, removing the peel for easier collection and processing. Vibration screening through the sieve frame improves the screening effect, facilitates the separation of coffee beans from the peel, and better meets usage requirements. This invention has a reasonable structure, which can better separate the peel and better meet usage needs. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Example: Please refer to Figures 1-5 An automatic coffee bean peeling device includes: a peeling tank 1, a tank cover 12 installed at one end of the peeling tank 1, a feed hopper 11 installed at the upper end of the peeling tank 1, a discharge pipe 13 installed at the lower right side of the peeling tank 1, a screening frame 3 arranged below the discharge pipe 13, and a sieve frame 31 slidably installed on the screening frame 3, the sieve frame 31 being inclined; a peeling mechanism installed inside the peeling tank 1 for peeling the coffee beans; a connecting mechanism arranged between the sieve frame 31 and the screening frame 3 for slidingly installing the sieve frame 31 on the screening frame 3; and a driving mechanism installed on the screening frame 3 for driving the sieve frame 31 to move.

[0024] The working principle of this utility model is as follows: In specific use, coffee beans are added to the peeling tank 1 through the feeding hopper 11. Then, the peeling mechanism peels the coffee beans. After peeling, the coffee beans and peels are discharged through the discharge pipe 13 and fall onto the screen frame 31. Then, the drive mechanism drives the screen frame 31 to vibrate up and down, which can carry out the screening work, so that the peels fall below the screen frame 31, completing the peel separation work, which can improve the separation effect and better meet the needs of use.

[0025] As a further embodiment, the peeling mechanism includes a peeling rotating shaft 2 rotatably installed inside the peeling tank 1. A first spiral peeling paddle 22 is mounted on the peeling rotating shaft 2. A first peeling motor 21 is also mounted on the right side of the peeling tank 1. The output end of the first peeling motor 21 is drivenly connected to the shaft end of the peeling rotating shaft 2. A peeling rotating sleeve 24 is also rotatably mounted on the tank cover 12. A second spiral peeling paddle 26 is mounted on the peeling rotating sleeve 24. A second peeling motor 25 is also mounted on the tank cover 12. The output end of the second peeling motor 25 is drivenly connected to the shaft end of the peeling rotating sleeve 24. In this embodiment, the spiral peeling paddle 22 and the second spiral peeling paddle 26 have opposite spiral directions.

[0026] The working principle of the peeling mechanism is as follows: Before peeling, the peeling rotating shaft 2 is driven to rotate in the opposite direction by the peeling motor 1 21, and the peeling rotating sleeve 24 is driven to rotate in the forward direction by the peeling motor 25. At this time, the spiral peeling paddle 1 22 and the spiral peeling paddle 26 can transport the raw material to the right side of the peeling tank 1 to facilitate the subsequent peeling work.

[0027] During peeling, peeling motor 1 21 and peeling motor 25 are started, which drive the peeling rotating shaft 2 and peeling rotating sleeve 24 to rotate in the forward direction, thereby realizing the rotation of spiral peeling paddle 1 22 and spiral peeling paddle 26. This causes the fruit to move towards the middle position of the peeling tank 1, causing friction and collision, thereby separating the coffee bean from the peel. By setting spiral peeling paddle 1 22 and spiral peeling paddle 26 with opposite spiral directions, the fruit can be gathered towards the middle position during peeling, making it easier to squeeze the fruit and thus facilitating the breaking and removal of the peel.

[0028] After peeling is completed, peeling motor 1 21 drives peeling rotating shaft 2 to rotate in the opposite direction, peeling motor 25 drives peeling rotating sleeve 24 to rotate in the forward direction, and spiral peeling paddle 1 22, together with spiral peeling paddle 26, can transport the raw material to the discharge pipe 13 on the right side of peeling tank 1, so as to facilitate the discharge of fruit peel and coffee beans.

[0029] To improve the stability of the peeling rotating sleeve 24, a peeling connecting shaft 23 extends from the end of the peeling rotating shaft 2, and the peeling connecting shaft 23 is rotatably inserted into the peeling rotating sleeve 24.

[0030] As a further embodiment, the connecting mechanism includes a connecting groove 32 opened on the screening frame 3, a connecting column 34 installed in the connecting groove 32, a connecting slider 33 slidably fitted on the connecting column 34, and the connecting slider 33 being fixedly connected to the screen frame 31.

[0031] By setting the connecting column 34 in conjunction with the connecting slider 33, the screen frame 31 can slide up and down, making it easier to screen and separate coffee beans and fruit peels in the screen frame.

[0032] As a further embodiment, the driving mechanism includes a driving frame 4 mounted on the screening frame 3. A driving shaft 42 is rotatably mounted inside the driving frame 4, and a driving cam 43 is mounted on the driving shaft 42. The driving cam 43 abuts against the sieve frame 31. A driving motor 41 is also mounted on the driving frame 4, and the output end of the driving motor 41 is drivenly connected to the driving shaft 42. In this embodiment, a recycling box for receiving fruit peels is provided directly below the sieve frame 31, and a collection box for receiving coffee beans is placed below the right end of the sieve frame 31.

[0033] The working principle of the drive mechanism is as follows: When driven, the drive motor 41 is started, which drives the drive shaft 42 to rotate, which in turn drives the drive cam 43 to rotate. The drive cam 43 pushes the sieve frame 31 to move, thereby causing the sieve frame 31 to vibrate. This allows the coffee beans inside the sieve frame to be screened, removing the fruit skins for easier collection and processing. Vibration screening through the sieve frame 31 improves the screening effect, facilitates the separation of coffee beans from the fruit skins, and better meets usage requirements.
