Description

Technical Field

[0001] This utility model relates to the field of coffee bean dehulling technology, specifically to a coffee bean dehulling machine with an anti-clogging structure. Background Technology

[0002] After the coffee beans are hulled, a thin layer of parchment and silver foil remains on the outside. Before further processing, the parchment and silver foil on the coffee beans need to be removed. The parchment is usually removed using a rolling dehulling machine, while the silver foil is usually removed using a friction dehulling machine. When dehulling, it is important to avoid over-hulling, otherwise the damage on the coffee beans will easily caramelize during subsequent roasting, thus affecting the taste of the coffee.

[0003] For example, Chinese patent CN221284558U discloses a coffee bean dehulling device. The device has a sieve plate and a partition door at the inclined downward end of the sieve plate in the feed hopper, so that the coffee beans are sieved into two batches of different sizes before entering the dehulling component, and then they are dehulled by dehulling block one and dehulling block two respectively.

[0004] However, blockages may occur during the hulling process of coffee beans. The device cannot automatically adjust its structure, and when blockages occur, it can only be stopped for cleaning, which delays the hulling time.

[0005] Based on this, this utility model designs a coffee bean hulling machine with an anti-clogging structure to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a coffee bean hulling machine with an anti-clogging structure.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A coffee bean dehulling machine with an anti-clogging structure includes a crushing and dehulling structure and two support platforms, as well as a sorting and feeding structure and an anti-clogging drive mechanism. The crushing and hulling structure is installed on the support platform on the right side, and a sorting and feeding structure is installed on the crushing and hulling structure to feed the coffee beans in order of size from small to large. The anti-blocking drive mechanism includes a drive structure and a pushing structure. The drive structure is installed on the support platform on the left side and is connected to the left side of the rolling and dehulling structure. The right side of the rolling and dehulling structure is equipped with a pushing structure to cooperate with the drive structure and prevent the rolling and dehulling structure from being blocked.

[0008] Furthermore, the crushing and hulling structure includes a box body and a rotating module. The box body forms a cone-shaped hulling chamber. The diameter of the left side of the hulling chamber is smaller than the diameter of the right side. The lower side of the box body is provided with an outlet for discharging the hulled coffee beans. The rotating module is installed inside the box body. The inlet of the box body is located on the upper side of the box body.

[0009] Furthermore, the rotating module includes a conical roller and baffles. The conical roller is located inside the shelling chamber and is conical in shape. The left end of the conical roller passes through the housing. The right end of the conical roller is connected to the pushing structure. Multiple baffles are evenly fixedly installed on the conical roller in a circumferential array.

[0010] Furthermore, the sorting and feeding structure includes a feeding hopper and a sorting rack. The feeding hopper is fixedly installed on the feeding port of the box body, and multiple sorting racks are fixedly installed on the feeding hopper. The sorting racks form a sorting trough for discharging coffee beans. The right side of the sorting rack is higher than the left side, and the left side of the sorting trough is smaller than the right side.

[0011] Furthermore, the drive structure includes a drive module and a self-adjusting transmission module. The drive module is mounted on a support platform, and the self-adjusting transmission module is connected to the left end of the conical roller.

[0012] Furthermore, the drive module includes a geared motor, a drive disk, and a set of inclined blocks. The geared motor is fixedly mounted on the support platform, and the drive disk is fixedly mounted on the output end of the geared motor. Multiple set of inclined blocks are evenly and uniformly fixedly mounted on the drive disk in a circular array.

[0013] Furthermore, the self-adjusting transmission module includes a transmission disc, two inclined blocks, a central cylinder, and a spring. The transmission disc is fixedly connected to the left end of the conical roller. Multiple inclined blocks are evenly and uniformly fixedly installed on the transmission disc in a circumferential array. A central cylinder is fixedly installed at the center of the drive disc and the transmission disc, respectively. The spring is located inside the two central cylinders. One end of the spring is fixedly connected to the drive disc, and the other end of the spring is fixedly connected to the transmission disc.

[0014] Furthermore, multiple inclined blocks 1 and inclined blocks 2 are distributed alternately; the inclined surface of inclined block 1 slides in contact with the inclined surface of inclined block 2.

[0015] Compared to existing technologies, the advantages of this invention are as follows: By setting up a sorting and feeding structure, smaller coffee beans fall to the right side of the crushing and hulling structure, while larger coffee beans fall to the left side. Then, a drive structure drives the crushing and hulling structure to operate, crushing and hulling coffee beans of different sizes. This ensures that coffee beans of different sizes are distributed and hulled according to their size within the crushing and hulling structure, preventing over-crushing of larger coffee beans, which could damage them and affect their quality. If the crushing and hulling structure becomes clogged during this process, the drive structure automatically adjusts and, in conjunction with a pushing structure, moves some components within the crushing and hulling structure to facilitate the removal of clogged material. Then, when the drive structure and pushing structure automatically reset, the crushing and hulling structure automatically resets, allowing the machine to continue hulling coffee beans without stopping, ensuring efficient hulling.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0021] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4 A coffee bean hulling machine with an anti-clogging structure includes a crushing and hulling structure 2 and two support platforms 1; it also includes a sorting and feeding structure 3 and an anti-clogging drive mechanism 4; The crushing and hulling structure 2 is installed on the support platform 1 on the right side. The crushing and hulling structure 2 is equipped with a sorting and feeding structure 3 for feeding coffee beans in order of size from small to large. like Figure 2 and Figure 4 As shown, the anti-blocking drive mechanism 4 includes a drive structure 41 and a pushing structure 42. The drive structure 41 is installed on the support platform 1 on the left side and is connected to the left side of the crushing and dehulling structure 2. The right side of the crushing and dehulling structure 2 is equipped with a pushing structure 42 to cooperate with the drive structure 41 to prevent the crushing and dehulling structure 2 from being blocked.

[0022] In this embodiment, when the coffee bean hulling machine with anti-clogging structure is working normally, coffee beans are fed in from the right side of the sorting and feeding structure 3. The coffee beans roll within the sorting and feeding structure 3 under the action of gravity. Through the setting of the sorting and feeding structure 3, smaller coffee beans fall to the right side of the crushing and hulling structure 2, and larger coffee beans fall to the left side of the crushing and hulling structure 2. Then, the driving structure 41 drives the crushing and hulling structure 2 to operate, and crushes and hulls coffee beans of different sizes. This allows coffee beans of different sizes to be distributed and hulled according to their size within the crushing and hulling structure 2, avoiding over-crushing of larger coffee beans, which would cause coffee bean damage and affect the quality of the coffee beans. If the crushing and hulling structure 2 becomes blocked during this process, the drive structure 41 will automatically adjust and cooperate with the pushing structure 42 to move some of the internal components of the crushing and hulling structure 2, so that the blocked material can fall off. Then, when the drive structure 41 and the pushing structure 42 automatically reset, the crushing and hulling structure 2 will automatically reset, so that the machine can continue to hull the coffee beans without stopping, thus ensuring hulling efficiency.

[0023] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figure 3 and Figure 4 As shown, the crushing and shelling structure 2 includes a box body 21 and a rotating module. The box body 21 contains a cone-shaped shelling chamber 22. The diameter of the left side of the shelling chamber 22 is smaller than that of the right side. The lower side of the box body 21 is provided with an outlet 25 for discharging the shelled coffee beans. The rotating module is installed inside the box body 21. The inlet of the box body 21 is located on the upper side of the box body 21. The rotating module includes a conical roller 23 and baffles 24. The conical roller 23 is located inside the shelling chamber 22 and is conical in shape. The left end of the conical roller 23 passes through the housing 21. The right end of the conical roller 23 is connected to the pushing structure 42. Multiple baffles 24 are evenly fixedly installed on the conical roller 23 in a circumferential array. like Figure 4 As shown, the sorting and feeding structure 3 includes a feeding hopper 31 and a sorting rack 32. The feeding hopper 31 is fixedly installed on the feeding port of the box 21, and multiple sorting racks 32 are fixedly installed on the feeding hopper 31. The sorting racks 32 form a sorting trough 33 for discharging coffee beans. The right side of the sorting rack 32 is higher than the left side, and the left side of the sorting trough 33 is smaller than the right side. like Figures 4-6 As shown, the drive structure 41 includes a drive module and a self-adjusting transmission module. The drive module is mounted on the support platform 1, and the self-adjusting transmission module is connected to the left end of the conical roller 23. The drive module includes a geared motor 411, a drive disk 412, and a wedge block 413. The geared motor 411 is fixedly mounted on the support platform 1, and the drive disk 412 is fixedly mounted on the output end of the geared motor 411. Multiple wedge blocks 413 are evenly and uniformly fixedly mounted on the drive disk 412 in a circular array. The self-adjusting transmission module includes a transmission disc 414, two inclined blocks 415, a central cylinder 416, and a spring 417. The transmission disc 414 is fixedly connected to the left end of the conical roller 23. Multiple inclined blocks 415 are evenly and uniformly fixedly installed in a circular array on the transmission disc 414. The center cylinders 416 are fixedly installed at the center of the drive disc 412 and the transmission disc 414, respectively. The spring 417 is located inside the two center cylinders 416. One end of the spring 417 is fixedly connected to the drive disc 412, and the other end of the spring 417 is fixedly connected to the transmission disc 414. Multiple inclined blocks 413 and 415 are staggered; the inclined surfaces of inclined blocks 413 and 415 slide in contact with each other. The pushing structure 42 includes a rotating support disk 421, an insert rod 423, and a second spring 425. The rotating support disk 421 is rotatably installed inside the housing 21, and multiple slots 422 are arranged in a circumferential array on the rotating support disk 421. Multiple conical rollers 23 are evenly fixedly installed in a circumferential array on the right end of the conical rollers 23. The insert rod 423 is inserted into the slots 422. An installation groove 424 is opened on the right side of the conical rollers 23 and at the center of the rotating support disk 421, and the second spring 425 is located in the installation groove 424. One end of the second spring 425 is fixedly connected to the conical rollers 23, and the other end of the second spring 425 is fixedly connected to the rotating support disk 421.

[0024] In this embodiment, when the crushing and shelling structure 2, the sorting and feeding structure 3, and the anti-blocking drive mechanism 4 are working normally, coffee beans are fed into the feeding hopper 31 from the right side of the sorting rack 32. By setting the right side of the sorting rack 32 to be higher than the left side and the left side of the sorting trough 33 to be smaller than the right side, the coffee beans move from right to left on the sorting rack 32. During this process, smaller coffee beans fall between the conical roller 23 on the right side and the box 21, while larger coffee beans fall between the conical roller 23 on the left side and the box 21. The geared motor 411 drives the drive disk 412 to rotate, which in turn drives multiple inclined blocks 413 to rotate. The inclined surface of the inclined block 413 is in contact with the inclined surface of the second inclined block 415, thus rotating through the second inclined block 415 and the transmission disk 414. The transmission disk 414 drives the conical grinding roller 23 to rotate, which in turn drives the baffle 24 to rotate and moves the coffee beans between two adjacent baffles 24 within the housing 21. During this process, the conical grinding roller 23 drives the rotating support disk 421 to rotate through the insert rod 423 and the slot 422. The coffee beans are crushed by the conical grinding roller 23, the baffle 24, and the inner wall of the housing 21, causing the outer shell of the coffee beans to detach. The dehulled coffee beans are discharged from the outlet 25. When a blockage occurs, the conical roller 23 cannot rotate. At this time, the geared motor 411 drives the drive disc 412 and the first inclined block 413 to rotate. The first inclined block 413 pushes the second inclined block 415 to move horizontally, thereby pushing the conical roller 23 to move horizontally through the second inclined block 415 and the transmission disc 414. The horizontal movement of the conical roller 23 drives the insertion rod 423 to move horizontally within the slot 422. At this time, the first spring 417 is stretched and the second spring 425 is compressed, thus causing the conical roller 23 to move horizontally within the shelling chamber. The conical roller 23 and the shelling chamber 22 move horizontally within the chamber. As the conical roller 23 and the shelling chamber 22 are conical, when the conical roller 23 moves to the right within the shelling chamber 22, any part of the conical roller 23 moves to a larger radius area, increasing the distance between the conical roller 23 and the inner wall of the chamber 21, thus facilitating the material to fall. After the material falls, spring 1 417 and spring 2 425 reset, thereby resetting the conical roller 23, the insert rod 423, the transmission disc 414, and the inclined block 2 415, and continuing the shelling process.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
