Description

Technical Field

[0001] This invention relates to the field of agricultural product processing technology, and in particular, to a fruit peeling device. Background Technology

[0002] In the processing of many fruit products, it is often necessary to remove their hard outer shells and extract the seeds inside. For example, the outer shell of the camellia fruit needs to be removed to extract the seeds for oil extraction. This often requires the use of mechanical equipment for automated shelling of these fruit products.

[0003] However, conventional shelling equipment usually shells the seeds by rotating and crushing them with a grinding disc, which can easily damage the seeds inside, causing them to break and affecting product quality. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a fruit peeling device that can reduce damage to the seeds during peeling.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A fruit peeling device includes: a frame; a fixed cylinder with openings at both ends, fixedly installed on the frame, and having first protrusions on its peripheral wall, wherein multiple sets of the first protrusions are arranged at vertical intervals, and the first protrusions in the same set are arranged at intervals around the same height; a rotating cylinder with a closed upper end, rotatably installed on the frame, and at least partially located inside the fixed cylinder, and having second protrusions on its peripheral wall, wherein multiple sets of the second protrusions are arranged at vertical intervals, and the second protrusions in the same set are arranged at intervals around the same height, and the first and second protrusions are staggered vertically; and a rotation drive mechanism connected to the rotating cylinder to drive the rotating cylinder to rotate.

[0007] Furthermore, the distance between the first protrusion and the center of the fixed cylinder is different in different groups, and the distance between the first protrusion and the center of the fixed cylinder increases with the height.

[0008] Furthermore, the fixed cylinder includes a vertical plate and an annular plate. The vertical plates are arranged in a circumferential, spaced arrangement. The annular plates are connected and fixed to the vertical plates. The annular plates are arranged in a vertical, spaced arrangement, and the diameter of the annular plates decreases from top to bottom. Two adjacent annular plates have a material passage gap for shells and seeds to pass through. The annular plates are provided with multiple sets of first protrusions corresponding to multiple sets. The first protrusions in the same set are installed on the same annular plate at the corresponding height.

[0009] Furthermore, the fixed cylinder also includes two annular end plates, which are connected to the upper and lower ends of the vertical plate; the frame includes a base plate connected to the lower annular end plate, and a plurality of vertically extending screws are installed on the base plate. Each of the two annular end plates has a first through hole corresponding to the screw for the screw to pass through. Each screw is threaded with two first fastening nuts, which clamp and fix the two annular end plates and the height of the fixed cylinder can be adjusted by adjusting the position of the first fastening nuts.

[0010] Furthermore, a cover is fixedly installed on the base plate, and the cover surrounds the outer periphery of the fixed cylinder; the base plate is provided with multiple discharge ports.

[0011] Furthermore, the frame also includes a mounting plate, which is sleeved on the screw and can be adjusted up and down. Two second fastening nuts are installed on each screw to clamp and fix the mounting plate. The mounting plate is located above the fixed cylinder. A first feeding annular cylinder is provided at the bottom of the mounting plate, and a second feeding annular cylinder is installed at the upper end of the annular end plate. The first feeding annular cylinder is sleeved on the second feeding annular cylinder, or the second feeding annular cylinder is sleeved on the first feeding annular cylinder, and their relative positions can be adjusted up and down. Feeding notches are provided at corresponding positions on the sides of the first and second feeding annular cylinders to form a feeding port. The relative up and down movement of the first and second feeding annular cylinders can adjust the height of the feeding port. The rotary drive mechanism is mounted on the mounting plate.

[0012] Furthermore, the rotating cylinder includes an inner cylinder and an outer cylinder detachably connected to the inner cylinder. The second protrusion is installed on the peripheral wall of the outer cylinder and protrudes from the outer cylinder. The inner cylinder is embedded in the outer cylinder and limits the inward movement of the second protrusion.

[0013] Furthermore, the second protrusion includes a cone head disposed outside the outer cylinder and a limiting head disposed at the inner end of the cone head and located inside the outer cylinder. The outer cylinder is provided with a mounting hole corresponding to the second protrusion. A groove is provided between the cone head and the limiting head for the edge of the mounting hole to be inserted. The limiting head is clamped between the inner cylinder and the outer cylinder.

[0014] Furthermore, the upper end of the inner cylinder is closed and the upper surface is provided with a material-pushing plate arranged in a circle to push the incoming material to the periphery; the upper end of the outer cylinder is provided with an inwardly extending connecting plate, the center of the connecting plate is provided with a clearance hole to avoid the material-pushing plate, and the connecting plate and the upper end of the inner cylinder are provided with corresponding holes to be connected and fixed by fasteners.

[0015] Furthermore, a central rotating shaft is inserted through the center of the inner cylinder, and the central rotating shaft is rotatably mounted on the frame.

[0016] The present invention has the following beneficial effects:

[0017] The rotating cylinder is driven to rotate by a rotary drive mechanism, which in turn drives the second convex post to rotate. The second convex post cooperates with the first convex post, and the first and second convex posts are vertically staggered. The rotation of the second convex post and the alternating compression of the fruit material with the first convex post achieves the peeling of the fruit material. Since the first and second convex posts are arranged in a circular and spaced manner and are vertically staggered, the material is not crushed and crushed in a completely closed manner like a grinding disc, thus reducing the damage to the seeds. The seeds will pass through the gaps between adjacent first convex posts, the gaps between adjacent second convex posts, and the gaps between the first and second convex posts and fall off, reducing the crushing and crushing damage to the seeds.

[0018] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

[0035] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a fruit peeling device, comprising a frame 100, a fixed cylinder 200, a rotating cylinder 300, and a rotating drive mechanism 400.

[0036] The fixed cylinder 200 has openings at both the top and bottom. The upper opening is for inserting materials, and the lower opening is for discharging materials. The fixed cylinder 200 is fixedly installed on the frame 100. The peripheral wall of the fixed cylinder 200 is provided with first protrusions 210. Multiple sets of first protrusions 210 are arranged vertically at intervals, and the first protrusions 210 in the same set are arranged at the same height and at intervals around each other. The upper end of the rotating cylinder 300 is closed to prevent materials from entering the rotating cylinder 300. The rotating cylinder 300 is rotatably installed on the frame 100. The rotating cylinder 300 is at least partially located inside the fixed cylinder 200. Specifically, in this embodiment, the rotating cylinder 300 is entirely located inside the fixed cylinder 200. The rotating cylinder 300 has a second protrusion 310 on its peripheral wall. The second protrusion 310 protrudes outward from the peripheral wall of the rotating cylinder 300. Multiple sets of the second protrusion 310 are arranged at intervals along the vertical direction. The second protrusion 310 in the same set are arranged at intervals around the same height. The first protrusion 210 and the second protrusion 310 are staggered along the vertical direction. The rotating drive mechanism 400 is connected to the rotating cylinder 300 to drive the rotating cylinder 300 to rotate.

[0037] This invention provides a fruit peeling device. A rotating cylinder 300 is driven to rotate by a rotating drive mechanism 400, which in turn drives a second protruding post 310 to rotate. The second protruding post 310 rotates in conjunction with a first protruding post 210, and the first and second protruding posts 210 are vertically staggered. The rotating second protruding post 310 and the first protruding post 210 alternately compress the fruit material, thus peeling the fruit. Typically, the fruit before peeling has been dried and its shell has already cracked. The rotating second protruding post 310 and the first protruding post 210... The 210 staggered compression method efficiently achieves shelling; and because the first protrusion 210 and the second protrusion 310 are arranged in a circumferential, spaced manner and vertically staggered, they do not crush the material in a completely enclosed manner like a grinding disc, thus reducing damage to the seeds. The seeds will pass through the gaps between adjacent first protrusions 210, adjacent second protrusions 310, and the gaps between the first and second protrusions 210 and fall off, reducing crushing damage to the seeds. Generally, it can be understood that the vertical gap between adjacent second protrusions 310 and first protrusions 210 is smaller than the diameter of the unshelled fruit material, but larger than the diameter of the seeds. This allows for shelling of the fruit material while minimizing damage to the seeds. After shelling, both the shell and the seeds pass through the gaps between adjacent first protrusions 210, adjacent second protrusions 310, and the gaps between the first and second protrusions 210 and fall off until they are finally discharged.

[0038] It is understandable that, in order to further reduce damage to the grains, the first protrusion 210 and the second protrusion 310 are made of materials with a certain elastic deformation capability, such as rubber, silicone, polyurethane, and rib rubber. In this embodiment, both the first protrusion 210 and the second protrusion 310 are made of rib rubber.

[0039] Reference Figure 3 and Figure 4 In some embodiments of the present invention, the distance between the first protrusion 210 of different groups and the center of the fixed cylinder 200 is different. The distance between the first protrusion 210 of different groups and the center of the fixed cylinder 200 increases with the height, that is, the first protrusion 210 gradually narrows from top to bottom, thereby enabling the peeling of materials of different diameters and realizing graded processing. Specifically, the part of the first protrusion 210 protruding into the fixed cylinder 200 is provided with a cone portion, which tapers towards the center of the fixed cylinder 200. This narrowing of the center distance of the first protrusion 210 results in a smaller vertical interval between the first protrusion 210 and the adjacent second protrusion 310, thereby enabling the peeling of materials with smaller diameters. The vertical interval between the first protrusion 210 and the adjacent second protrusion 310 gradually decreases from top to bottom, thereby achieving a more comprehensive step-by-step peeling.

[0040] Reference Figure 4 In a further embodiment of the present invention, the fixed cylinder 200 includes a vertical plate 220 and an annular plate 230. The vertical plates 220 are arranged in a circumferential pattern at intervals. The annular plate 230 is connected and fixed to the vertical plates 220. The annular plates 230 are arranged in a vertical pattern at intervals, and the diameter of the annular plates 230 decreases from top to bottom. The annular plate 230 is provided with multiple sets of first protrusions 210. The first protrusions 210 in the same set are installed on the same annular plate 230 at the same height, so that the distance between the first protrusion 210 and the center of the fixed cylinder 200 gradually decreases from top to bottom. The position change of the annular plate 230 drives the position change of the first protrusion 210, so that the same specification of first protrusion 210 can be used, reducing design and production costs. The two adjacent annular plates 230 have a material passage gap 240 for shells and seeds to pass through. The size of the material passage gap 240 is not large enough for whole fruit materials to pass through, but the shells and seeds formed after peeling can pass through. The annular plates 230 gradually narrow from top to bottom, so the peeled material can more easily leave the fixed cylinder 200 directly through the material passage gap 240, thereby avoiding collision and squeezing by the first protrusion 210 and the second protrusion 310 below, further reducing damage to the seeds, and effectively preventing material from accumulating below the fixed cylinder 200. The material passage gap 240 can effectively divert the material, allowing some of the peeled material to be directly discharged from the fixed cylinder 200, reducing the amount of material passing between the bottom of the fixed cylinder 200 and the rotating cylinder 300, reducing blockage or crushing and damage caused by material accumulation. In addition, since the first protrusion 210 and the second protrusion 310 are vertically staggered, and the material passage gap 240 is formed between the upper and lower adjacent first protrusions 210, there will be a set of second protrusions 310 at the height of the material passage gap 240. This allows the second protrusion 310 to rotate and push the material (shell and seeds) formed after shelling outward, so that more material can be discharged directly from the material passage gap 240.

[0041] Reference Figure 4 In a further embodiment of the present invention, the fixing cylinder 200 further includes two annular end plates 250, which are connected to the upper and lower ends of the vertical plate 220; the frame 100 includes a base plate 110 connected to the lower annular end plate 250, and a plurality of vertically extending screws 120 are installed on the base plate 110. Each of the two annular end plates 250 is provided with a first through hole 260 corresponding to the screw 120 for the screw 120 to pass through. Each screw 120 is threaded with two first fastening nuts 130, which clamp and fix the two annular end plates 250. The upper first fastening nut 130 abuts against the top surface of the upper annular end plate 250, and the lower first fastening nut 130 abuts against the bottom surface of the lower annular end plate 250. Thus, the two annular end plates 250 and the fixing cylinder 200 are clamped and fixed by the upper and lower first fastening nuts 130. Furthermore, the height of the fixing cylinder 200 can be adjusted by adjusting the position of the first fastening nuts 130. The height of the fixing cylinder 200 is adjusted by rotating the first fastening nuts 130 on the screw 120, thus facilitating equipment debugging and ensuring the height of the fixing cylinder 200 is adjusted to a suitable position. It can be understood that multiple screws 120 are arranged in a circular pattern, thereby achieving multiple positions for installing and fixing the fixing cylinder 200.

[0042] Reference Figure 1 and Figure 2 In a further embodiment of the present invention, a cover 140 is fixedly installed on the base plate 110, and the cover 140 surrounds the outer periphery of the fixed cylinder 200; the base plate 110 is provided with a plurality of discharge ports 150. The cover 140 prevents the material that escapes from the material passage gap 240 from overflowing, thereby surrounding the outer periphery of the fixed cylinder 200, so that the material subsequently falls uniformly from the discharge ports 150 of the base plate 110.

[0043] Reference Figures 1 to 3In a further embodiment of the present invention, the frame 100 further includes a mounting plate 160, which is sleeved on the screw 120 and can be adjusted up and down. Specifically, the mounting plate 160 has a through hole for the screw 120 to pass through, thus allowing it to be sleeved on the screw 120 and adjusted in position along the screw. Two second fastening nuts 170 are installed on each screw 120, which are used to clamp and fix the mounting plate 160, thereby achieving the installation and fixation of the mounting plate 160. The mounting plate 160 is located above the fixed cylinder 200. The bottom of the mounting plate 160 is provided with a first feeding annular cylinder 180, and the upper end of the annular end plate 250 is provided with a second feeding annular cylinder 270. The first feeding annular cylinder 180 is sleeved on the second feeding annular cylinder 270 or the second feeding annular cylinder 270 is sleeved on the first feeding annular cylinder 180 and can be adjusted in relative height. That is, the first feeding annular cylinder 180 and the second feeding annular cylinder 270 are sleeved and their relative positions can be adjusted in height. The sides of the first feeding annular cylinder 180 and the second feeding annular cylinder 270 are provided with feeding notches to form a feeding port 101. The material enters between the fixed cylinder 200 and the rotating cylinder 300 from the feeding port 101. The height of the feed inlet 101 can be adjusted by the relative lifting and lowering of the first feed annular cylinder 180 and the second feed annular cylinder 270. This adjustment of the feed inlet 101 is achieved by adjusting the height of the mounting plate 160. The rotary drive mechanism 400 is mounted on the mounting plate 160, which provides a suitable mounting position for the rotary drive mechanism 400 without affecting the feeding.

[0044] Reference Figure 5 and Figure 6 In some embodiments of the present invention, the rotating cylinder 300 includes an inner cylinder 320 and an outer cylinder 330 detachably connected to the inner cylinder 320. The second protrusion 310 is installed on the peripheral wall of the outer cylinder 330 and protrudes from the outer cylinder 330. The inner cylinder 320 is embedded in the outer cylinder 330 and limits the inward movement of the second protrusion 310. Thus, when the rotating cylinder 300 rotates, the second protrusion 310 will not retract inward and affect the peeling process of the material. Furthermore, the inner cylinder 320 and the outer cylinder 330 are detachably connected, thereby facilitating the installation, disassembly and maintenance of the second protrusion 310.

[0045] Reference Figure 6In a further embodiment of the present invention, the second protrusion 310 includes a cone 311 disposed outside the outer cylinder 330 and a limiting head 312 disposed at the inner end of the cone 311 and located inside the outer cylinder 330. The outer cylinder 330 is provided with a mounting hole corresponding to the second protrusion 310. A groove 313 is provided between the cone 311 and the limiting head 312 for the edge of the mounting hole to be inserted. The limiting head 312 is sandwiched between the inner cylinder 320 and the outer cylinder 330. The second protrusion 310 is positioned and installed by inserting the groove 313 into the edge of the mounting hole. The contour of the limiting head 312 is larger than the mounting hole, so that the position of the second protrusion 310 is stable. In addition, the cone 311 facilitates the installation process by passing through the mounting hole. Furthermore, the design of the cone 311 allows for a certain range of variation in its diameter, enabling the material to adaptively adjust its position to contact the cone 311, reducing the crushing damage to the seeds. In addition, the cone head 311 is adapted to the cone portion of the first protrusion 210, so that when the distance between the first protrusion 210 and the center of the fixed cylinder 200 changes, the distance between the cone head 311 and the cone portion will change synchronously.

[0046] Reference Figure 5 and Figure 6 In a further embodiment of the present invention, the upper end of the inner cylinder 320 is closed and the upper end surface is provided with a circumferentially arranged material-pushing plate 340, which is used to push the incoming material to the periphery to prevent the material from accumulating at the upper end of the inner cylinder 320. The rotating material-pushing plate 340 can also evenly push the material between the fixed cylinder 200 and the rotating cylinder 300 for peeling. To prevent the material from being pushed outside the fixed cylinder 200, such as... Figure 3 As shown, the material-pushing plate 340 is lower than the upper end of the fixed cylinder 200, that is, the material-pushing plate 340 is completely inside the fixed cylinder 200; the upper end of the outer cylinder 330 is provided with an inwardly extending connecting plate 350, the center of the connecting plate 350 is provided with a clearance hole to avoid the material-pushing plate 340, and the upper end of the connecting plate 350 and the inner cylinder 320 are provided with corresponding holes for connection and fixation by fasteners, thereby realizing the detachable connection between the inner cylinder 320 and the outer cylinder 330, which facilitates installation and subsequent disassembly and maintenance.

[0047] Reference Figure 3 and Figure 5 In some embodiments of the present invention, a central rotating shaft 360 is inserted through the center of the inner cylinder 320, and the central rotating shaft 360 is rotatably mounted on the frame 100. Specifically, the upper and lower ends of the central rotating shaft 360 extend out of the inner cylinder 320, and both the bottom plate 110 and the mounting plate 160 are equipped with bearing seats for the ends of the central rotating shaft 360 to pass through. Bearings are installed in the bearing seats to reduce the rotational friction of the central rotating shaft 360.

[0048] Specifically, the rotary drive mechanism 400 includes a motor and a reduction mechanism. The output shaft of the motor is connected to the reduction mechanism, which has an output shaft connected to the central rotating shaft 360, thereby realizing the rotational drive of the rotating cylinder 300. Furthermore, the output shaft and the central rotating shaft 360 are adjustable in position while maintaining torque transmission. For example, if the bottom of the output shaft is a regular hexagon, and the upper surface of the central rotating shaft 360 has a corresponding regular hexagonal hole, torque transmission is achieved by inserting the bottom of the output shaft into the regular hexagonal hole. The bottom of the output shaft can move up and down within the regular hexagonal hole without affecting the rotation of the central rotating shaft 360.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
