[0048] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0049] Reference Figure 1 as well as Figure 3 According to an embodiment of the present invention, the shrimp shell peeling machine includes a frame 10, a shell peeling assembly 20, a material blocking assembly 30 and a driving assembly 40. The shell peeling assembly 20 is arranged on the frame 10, and the shell peeling assembly 20 includes a rotatable active roller 21 and a driven roller 22. The driven roller 22 is arranged on both sides of the active roller 21. The axes of the active roller 21 and the driven roller 22 are parallel to each other and inclined. There is a gap between the active roller 21 and the driven roller 22, and the size of the gap is adjustable. The rotation directions of the active roller 21 and the driven roller 22 are opposite. The active roller 21 and the driven roller 22 are used for material shell peeling; the material blocking assembly 30 is arranged on the frame 10 and is located at the shell peeling position. Above the component 20, the material blocking component 30 is respectively arranged between the active roller 21 and the driven roller 22. The material blocking component 30 includes a baffle 31. The baffle 31 is arranged on the gap between the active roller 21 and the driven roller 22. The baffle 31 is used to slow down the movement speed of the material; the driving component 40 is arranged on the frame 10 and is located at one end of the shelling component 20. The output end of the driving component 40 is connected to the active roller 21 and the driven roller 22. The driving component 40 is used to drive the active roller 21 and the driven roller 22 to rotate.

[0050] The shelling assembly 20 is mounted on the frame 10 at both ends. Specifically, both ends of the rotating shafts of the driving roller 21 and the driven roller 22 are mounted on the frame 10, with one end of the rotating shaft being higher than the other. Therefore, the shelling assembly 20 is tilted on the frame 10. When shrimp is introduced into the higher end, the driving roller 21 and the driven roller 22 in the shelling assembly 20 rotate in opposite directions. In the gap between the driving roller 21 and the driven roller 22, the shrimp is squeezed, rubbed, and torn by the driving roller 21 and the driven roller 22, thereby separating the shrimp from the shells. The shrimp shells then pass through the gap between the driving roller 21 and the driven roller 22 and slide down from the bottom, while the shrimp slide down along the tilted direction. It is important to note that the tilt angle of the shelling assembly 20 is not specifically limited. To facilitate the shrimp from sliding down, the tilt angle should not be too small. However, to ensure that the shrimp remains in the shelling assembly 20 for a longer period of time, the tilt angle can be appropriately reduced to slow the shrimp from sliding down.

[0051] In some embodiments, the gap between the active roller 21 and the driven roller 22 is adjustable. By changing the positions of the ends of the active roller 21 and the driven roller 22, the gap between the active roller 21 and the driven roller 22 can be varied. It is conceivable that the active roller 21 and the driven roller 22 with an adjustable gap can accommodate different shrimp species and can also be used to shell shrimp of different sizes.

[0052] The retaining assembly 30 above the shelling assembly 20 includes a baffle 31. This baffle 31 is located above the gap between the driving roller 21 and the driven roller 22, i.e., within the shrimp. As the shrimp slides down, the baffle 31 slows down the shrimp, thereby extending the time the shrimp remains in the shelling assembly 20 and, consequently, the shelling time.

[0053] Furthermore, the shrimp shelling machine is further provided with a drive assembly 40. The output end of the drive assembly 40 is connected to the active roller 21 and the passive roller 22 of the shelling assembly 20, thereby driving the active roller 21 and the passive roller 22 to rotate relative to each other, thereby peeling the shrimp shells. In some embodiments, passive rollers 22 may be provided on both sides of the active roller 21. The drive assembly 40 drives the active roller 21 and the passive roller 22 to rotate forward and reverse, thereby rotating the active roller 21 and the passive roller 22 in opposite directions, thereby achieving the purpose of peeling the shrimp shells. It should be noted that when the active roller 21 rotates forward and cooperates with the first passive roller 22 to peel the shrimp shells, the second passive roller 22 can stop rotating, reducing energy consumption. When the active roller 21 rotates reversely and cooperates with the second passive roller 22, the second passive roller 22 rotates forward and the first passive roller 22 stops rotating.

[0054] Therefore, the shrimp shelling machine according to the embodiment of the present invention has at least the following beneficial effects: the driving roller 21 and the driven roller 22 rotate in opposite directions, thereby removing the shrimp shells due to friction. The gap between the driving roller 21 and the driven roller 22 can also be adjusted to accommodate shrimp of different sizes and varieties. Furthermore, the baffle 31 of the material retaining assembly 30 blocks the shrimp in the shelling area, significantly increasing the shrimp's residence time between the driving roller 21 and the driven roller 22, thereby further facilitating shrimp shelling.

[0055] Reference Figures 1 to 3 In some embodiments of the present invention, the shrimp shelling machine includes multiple groups of shelling assemblies 20, which are arranged in sequence on a frame 10. The shelling assemblies 20 are provided with multiple working sections 23, each corresponding to a driving roller 21 and a driven roller 22. A material dropout 231 is provided between adjacent working sections 23 for dropping the material. Specifically, the multiple groups of shelling assemblies 20 are arranged on the frame 10, and the shelling assemblies 20 can simultaneously shell the shrimp material without interfering with each other, thereby greatly improving the efficiency of shrimp shelling. In addition, each group of shelling assemblies 20 is provided with multiple working sections 23. The driving roller 21 and the driven roller 22 are mounted on the rotating shaft of each working section 23, forming the shrimp shelling working section 23. By providing a feeding port at the upper end of each working section 23, shrimp feed can be simultaneously fed into each working section 23 of each set of shelling assemblies 20, and the shelling process can be performed in each working section 23, thereby greatly improving the efficiency of shelling. After being shelled in the working section 23, the shrimp meat slides to the lower end of the working section 23 and is discharged through the feeding port 231.

[0056] Further, refer to Figure 2 In some embodiments of the present invention, a first collection trough is provided below the discharge port 231 to collect the shelled shrimp. The first collection trough can be elongated and located below the working section 23 at the same height. It is used to receive the shrimp peeled from the discharge port 231 of the working section 23 at the same height of each shelling assembly 20. Therefore, it can be understood that the shrimp peeling machine housing is provided with multiple first collection troughs, each corresponding to each working section 23, and used to collect the shrimp peeled from each working section 23.

[0057] Reference Figures 2 to 4In some embodiments of the present invention, the drive assembly 40 includes a drive member 41 and a drive rack 42. The drive member 41 is mounted on the frame 10; one end of the drive rack 42 is connected to the output end of the drive member 41 via a connecting rod 421. The drive rack 42 is connected to the active roller 21 and the passive roller 22 via a gear train. Specifically, the drive member 41 can be a drive motor that can control the forward and reverse rotation of the output end, thereby driving the rack 42 to slide back and forth via the connecting rod 421, thereby controlling the reciprocating rotation of the active roller 21 and the passive roller 22 via the gear train.

[0058] Furthermore, in some embodiments of the present invention, the mounting position of the connecting rod 421 at the output end of the driver 41 is adjustable. Specifically, one end of the connecting rod 421 is hinged to one end of the drive rack 42, while both ends of the connecting rod 421 can be mounted at different positions on the output end of the driver 41. For example, a turntable is provided at the output end of the driver 41, and a plurality of mounting positions are provided around the turntable for mounting the connecting rod 421. By varying the mounting positions, the travel distance between the output end and the drive rack 42 can be varied, thereby controlling the sliding travel of the drive rack 42, ultimately varying the rotational travel of the active roller 21 and the driven roller 22, and thus varying the shelling travel between the active roller 21 and the driven roller 22.

[0059] Reference Figure 4 In some embodiments of the present invention, the gear train specifically includes a drive gear 43, a primary transmission gear 44, and a secondary transmission gear 45. The drive gear 43 is connected to the active roller 21 and the passive roller 22, respectively. The primary transmission gear 44 meshes with the drive gear 43 on the active roller 21. The drive gear 43 of each passive roller 22 meshes with two secondary transmission gears 45, respectively. The drive gear 43 of the active roller 21 drives the two secondary transmission gears 45 to rotate via the primary transmission gear 44. The drive rack 42 meshes with the drive gear 43 of each active roller 21 of the shelling assembly 20. The reciprocating drive rack 42 drives the active roller 21 to reciprocate. The drive gear 43 of the active roller 21 then drives the primary transmission gear 44 to reciprocate, which in turn drives the secondary transmission gears 45 on both sides to reciprocate, thereby driving the two passive rollers 22 to rotate forward and reverse.

[0060] It should be noted that in some embodiments of the present invention, the drive assembly 40 is capable of controlling the forward and reverse rotation of the active roller 21. One end of the driven roller 22 is connected to the drive gear 43 of the driven roller 22 via a first one-way bearing. One end of the driven roller 22 is also connected to the frame 10 via a second one-way bearing. Specifically, when the drive rack 42 drives the drive gear 43 of the active roller 21 in forward rotation, the primary transmission gear 44 rotates in reverse, causing the two secondary transmission gears 45 to rotate forward simultaneously, ultimately causing the drive gears 43 of both driven rollers 22 to simultaneously rotate in reverse. It should be understood that when the active roller 21 rotates forward, the driven roller 22 located to the right of the active roller 21 cooperates with the driven roller 22 to peel the shrimp shells through mutual compression and friction between the active roller 21 and the driven roller 22. However, the driven roller 22 located to the left of the active roller 21 rotates in the opposite direction to the active roller 21, but is located in the gap between them and does not experience compression or friction. Therefore, this driven roller 22 cannot cooperate with the active roller 21 to peel the shrimp shells.

[0061] Conversely, when the drive rack 42 drives the drive gear 43 of the active roller 21 in reverse rotation, the primary transmission gear 44 rotates forward, causing the two secondary transmission gears 45 to simultaneously rotate in reverse, ultimately causing the drive gears 43 of the two driven rollers 22 to simultaneously rotate forward. It should be understood that when the active roller 21 rotates in reverse, the driven roller 22 located to the left of the active roller 21 cooperates with the driven roller 22 to peel the shrimp shells through mutual compression and friction between the active roller 21 and the driven roller 22. However, the driven roller 22 located to the right of the active roller 21 rotates in the opposite direction to the active roller 21, but is located in the gap between them and does not experience compression or friction. Therefore, this driven roller 22 cannot cooperate with the forward-rotating active roller 21 to peel the shrimp shells.

[0062] Reference Figure 6 as well as Figure 7 In some embodiments, when the active roller 21 and one of the driven rollers 22 cooperate to peel the shelled fruit, the other driven roller 22 can stop rotating due to the action of the first one-way bearing. Since the first one-way bearing is disposed within the drive gear 43, the drive gear 43 of the driven roller 22 and the outer ring of the first one-way bearing can rotate under the drive of the secondary transmission gear 45, while the rotating shaft of the driven roller 22 and the inner ring of the first one-way bearing stop rotating.

[0063] It should also be noted that a second one-way bearing is also provided in the frame 10. The rotating shaft of the driven roller 22 is mounted on the frame 10 via the second one-way bearing. The second one-way bearing is arranged in the same direction as the first one-way bearing, thereby preventing the driven roller 22 from rotating relative to the frame 10. Specifically, in some embodiments, when the driving roller 21 rotates forward and the right driven roller 22 rotates counterclockwise to cooperate in shelling, the left driven roller 22 may rotate in the opposite direction of the driving roller 21 due to the influence of the driving roller 21 and the shrimp shell. However, the rotation direction of the driven roller 22 and the rotation direction of the driving roller 21 prevent friction and compression at the shelling position. To prevent the driven roller 22 from rotating counterclockwise, that is, to prevent the shrimp shell from being carried back to the shelling position and causing imperfect shelling, the second one-way bearing is used to prevent the driven roller 22 from rotating in the opposite direction relative to the frame 10.

[0064] In some embodiments of the present invention, the mounting position of the bearing seat (not shown) of the driven roller 22 relative to the frame 10 is adjustable. The bearing seats of the two driven rollers 22 are movably disposed on the frame 10, and the gap between the driven roller 22 and the driving roller 21 can be adjusted by adjusting the mounting position of the bearing seats. It is understood that by ensuring that the drive rack 42 transmits the primary transmission gear 44, and the primary transmission gear 44 transmits the secondary transmission gear 45, and then moving the position of the shaft seat on which the driven roller 22 is located, thereby moving the drive gear 43 on the driven roller 22, while ensuring that the center distance between the drive gear 43 of the driven roller 22 and the secondary transmission gear 45 remains unchanged, the gap between the driving roller 21 and the driven roller 22 can be changed by changing the distance between the drive gear 43 of the driving roller 21 and the drive gear 43 of the driven roller 22.

[0065] Reference Figure 2 as well as Figure 5 In some embodiments of the present invention, the retaining assembly 30 further includes a water supply pipe 32 and a nozzle 33. Both ends of the water supply pipe 32 are disposed on the frame 10 and above the driven roller 22. The water supply pipe 32 is connected to a water supply system and is provided with a plurality of baffles 31 arranged in an array, inclined in the direction of the material's descent. The nozzles 33 are disposed on the water supply pipe 32, and water is sprayed toward the opposing retaining assemblies 30. Specifically, the water supply system supplies water to the water supply pipe 32, which is then sprayed from the nozzles 33 on the water supply pipes 32. The two water supply pipes 32 above the two driven rollers 22 are arranged opposite each other, and the nozzles 33 face each other, spraying water toward the baffles 31 on the opposing water supply pipes 32. This not only facilitates shelling between the driving roller 21 and the driven roller 22, but also facilitates the shrimp material's descent and discharge from the shelling assembly 20. The baffle 31 is inclined along the inclined direction of the shelling assembly 20, thereby facilitating the dropping of the shrimp materials.

[0066] Reference Figure 5 , further, in some embodiments of the present invention, the baffles 31 of the relatively arranged material blocking assemblies 30 are arranged at intervals in sequence, and the nozzles 33 of the relatively arranged material blocking assemblies 30 are arranged at intervals in sequence. The material blocking assembly 30 cooperates with the shelling assembly 20 to extend the shelling time. Specifically, the shrimp feed is put into the upper end of the working section 23, and is first blocked by the baffle 31 on the higher material blocking assembly 30, and the active roller 21 and the driven roller 22 begin to shell the shrimp feed; when the active roller 21 reverses, the active roller 21 cooperates with the inclined baffle 31 and the water flow of the nozzle 33 to bring the shrimp feed from the gap on one side to the gap between the active roller 21 and the driven roller 22 on the other side, and at the same time is blocked by the baffle 31 of another set of relatively arranged material blocking assemblies 30 and then uses the active roller 21 and the driven roller 22 to move the shrimp feed from the gap on one side to the gap between the active roller 21 and the driven roller 22 on the other side. The active roller 22 peels the shrimp; when the active roller 21 rotates again, the active roller 21 cooperates with the inclined baffle 31 and the water flow from the nozzle 33 to carry the shrimp from the gap on one side to the gap between the active roller 21 and the driven roller 22 on the other side. At the same time, the baffle 31 of the opposite material blocking assembly 30 blocks the shrimp. The active roller 21 and the driven roller 22 continue to peel the shrimp. This cycle prevents the shrimp from being washed away by the water flow and greatly prolongs the shrimp's stay in the shelling assembly 20, thereby improving the shelling quality. A nozzle 33 is provided above each baffle 31 to prevent the shrimp from staying in the same position and hindering its shedding.

[0067] Reference Figure 2 as well as Figure 7 In some embodiments of the present invention, the shrimp shelling machine further includes a cleaning assembly 50, which is disposed on one side of the shelling assembly 20 and is connected to a water supply system. The cleaning assembly 50 is provided with a spray port (not shown in the figure) that sprays water toward the outer periphery of the active roller 21 and the outer periphery of the driven roller 22. Furthermore, in some embodiments of the present invention, the cleaning assembly 50 includes a spray pipe 51 having a plurality of spray ports arranged therein. The spray pipes 51 are located on one side of the active roller 21 and the outer periphery of the driven roller 22, respectively. The spray ports disposed on the outer periphery of the active roller 21 and the outer periphery of the driven roller 22 are aligned with the outer periphery of the active roller 21 and the outer periphery of the driven roller 22, thereby allowing the high-pressure water flow from the water supply system to flush away the shrimp shells on the outer periphery of the active roller 21 and the outer periphery of the driven roller 22.

[0068] Reference Figure 7In some embodiments of the present invention, a spray pipe 51 located on one side of the driving roller 21 is positioned directly below the driving roller 21. The cross-section of the spray pipe 51 is diamond-shaped. One of the sharp corners of the diamond is aligned with the driving roller 21, and the spray port of the spray pipe 51 is located at the sharp corner. When the spray pipe 51 sprays high-pressure water from the spray port, shrimp shells that fall off the driving roller 21 slide down the two intersecting sides of the diamond-shaped pipe, allowing the shrimp shells to fall quickly.

[0069] In some embodiments of the present invention, the cleaning assembly 50 further includes a second collection trough (not shown) located below the spray nozzle of the spray pipe 51. This second collection trough is used to collect wastewater from cleaning. The second collection trough can be positioned below each working section 23 to collect shrimp shells and wastewater that have fallen from the working section 23. To ensure that this does not interfere with the first collection trough's ability to collect shrimp, the first collection trough can be positioned below the second collection trough. In this case, the first collection trough can simultaneously collect the shelled shrimp from each working section 23.

[0070] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
