Description

Technical Field

[0001] This utility model relates to the field of chili processing, specifically to a chili peeling device. Background Technology

[0002] Peeling is a crucial step in the processing of chili peppers, and it is widely used in the production of chili powder, chili flakes, canned chili peppers, and peeled chili peppers.

[0003] Traditional chili peeling relies on manual labor, achieved through hand rubbing, tearing, or shaving. This method is inefficient, labor-intensive, and costly. Furthermore, workers are prone to skin burns and swelling due to contact with capsaicin, which does not meet the needs of modern large-scale production. Utility Model Content

[0004] The present invention aims to provide a device for peeling chili peppers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A chili peeling device includes a base connected to a support frame, a drum screen rotatably connected to the support frame, a stepper motor connected to the base, a rotating shaft connected to the output end of the stepper motor, a drive roller connected to the rotating shaft, the drive roller being movably connected to the drum screen, a vertical plate connected to the base, the rotating shaft being rotatably connected to the vertical plate, a platform connected to the base, a feed hopper connected to the platform, a crushing roller rotatably connected to the feed hopper, two sets of crushing rollers, each set of crushing rollers being connected to gears, the two sets of gears meshing with each other, a servo motor connected to the feed hopper, the output end of the servo motor being connected to any one of the crushing rollers, a discharge plate connected to the feed hopper, the discharge plate extending into the drum screen, and a cantilever frame connected to the base; the cantilever frame is detachably connected to a cleaning mechanism for cleaning the drum screen.

[0007] Preferably, the cleaning mechanism includes a cleaning brush, the cantilever is detachably connected to a mounting plate, the cleaning brush is slidably connected to the mounting plate, the mounting plate is connected to a spring, the other end of the spring is connected to the cleaning brush, the cleaning brush abuts against the drum screen, and the mounting plate is connected to a handle.

[0008] Preferably, the mounting plate is connected to a telescopic rod, and the telescopic end of the telescopic rod is connected to the cleaning brush.

[0009] Preferably, the mounting plate and the cantilever frame are connected by a common threaded fixing bolt.

[0010] Preferably, the rotating shaft and the drive roller are provided in two sets, the two sets of rotating shafts are respectively connected to pulleys, and the two sets of pulleys are connected to a rotating belt.

[0011] Preferably, the base is connected to a fixed seat, the fixed seat is rotatably connected to a driven roller, and the driven roller is movably connected to the drum screen.

[0012] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0013] (1) This solution uses a feeding hopper, crushing rollers, gears, and a servo motor. Two sets of crushing rollers are driven by gear meshing, which can uniformly crush the chili peppers and break down the toughness of the chili pepper skin, laying the foundation for subsequent peeling. This avoids the problems of compression deformation or incomplete crushing caused by single roller crushing, and is especially suitable for the pretreatment of chili peppers of different maturity. The servo motor drives a single set of crushing rollers, and synchronous reverse rotation is achieved through gear linkage, which ensures stable power transmission and avoids chili pepper jamming or uneven crushing. By setting a stepper motor, a rotating shaft, and an active roller, the stepper motor drives the active roller through the rotating shaft, which drives the drum screen to rotate. The rotation of the drum screen causes the crushed chili peppers to tumble inside the screen, and the skin and pulp are separated by friction and screening: the skin is retained outside the screen due to its large volume, while the pulp and seeds fall through the screen holes, achieving efficient peeling. Through the coordinated operation of components such as the feeding hopper, crushing rollers, and drum screen, the efficiency is increased by more than 100 times, meeting the needs of modern large-scale production. Furthermore, it requires no continuous human supervision, only periodic monitoring of equipment operation and replenishment of raw materials, significantly reducing labor input and effectively changing the inefficient situation of traditional manual operation. Stable mechanical operation ensures continuous and consistent production, reducing overall production costs. Moreover, operators only need to perform simple feeding and monitoring tasks, without direct contact with chili peppers, fundamentally eliminating health risks caused by capsaicin exposure, protecting worker health, and meeting modern safety production requirements.

[0014] (2) By setting up a cleaning mechanism, the cleaning brush is connected to the mounting plate via a spring. The spring force keeps it in constant contact with the surface of the drum screen, which can effectively remove the chili pepper fibers clogging the screen holes, avoiding frequent manual shutdowns for cleaning and improving the continuous operation capability of the equipment. The buffering effect of the spring avoids damage to the screen due to hard contact, while ensuring uniform cleaning force. The addition of a handle makes it easy to disassemble and remove the cleaning mechanism for maintenance or replacement.

[0015] (3) By setting telescopic rods, the cleaning brush is prevented from shifting, so that the cleaning brush always keeps in contact with the drum screen, thus achieving efficient cleaning of the drum screen, reducing manual cleaning, reducing labor, and effectively improving work efficiency.

[0016] (4) By setting fixing bolts, it is easy to quickly disassemble the cleaning brush for maintenance or replacement.

[0017] (5) By setting up pulleys and rotating belts, a synchronous transmission structure is formed to ensure that the driving force of the double active rollers on the drum screen is uniform and consistent, so as to avoid the drum screen from shifting or jamming due to uneven force, and improve the stability of equipment operation.

[0018] (6) By setting a fixed seat and driven rollers, a multi-point support structure is formed to share the load when the drum screen rotates, reduce the wear of the driving roller and bearing, and extend the service life of the equipment. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0024] like Figure 1-3The chili peeling device shown includes a base 4, which can be fixed to the ground with anchor bolts to ensure the stability of the equipment during operation. Support frames 5 are connected to both ends of the top of the base 4, and the two support frames 5 are rotatably connected to a cylindrical drum screen 1. The drum screen 1 has spiral guide ribs on its inner wall to guide the chilies to move axially and tumble evenly. A stepper motor 12 is connected to the top of the base 4, and a rotating shaft 11 is connected to the output end of the stepper motor 12. A drive roller 7 is connected to the other end of the rotating shaft 11. The drive roller 7 is movably connected to the drum screen 1. The surface of the drive roller 7 is made of rubber, and when it contacts the outer wall of the drum screen 1, it drives the screen to rotate through friction. The rubber material increases friction and reduces metal-on-metal collision noise. A vertical plate 8 is connected to the top of the base 4, and the rotating shaft 11 is rotatably connected to the vertical plate 8. The stepper motor 12 drives the double drive rollers 7 to rotate via a rotating belt 9, thus rotating the drum screen 1. The chili pepper mixture tumbles within the sieve under centrifugal and frictional forces. Because the seeds are smaller than the sieve openings, they pass through the sieve and fall out, while the skins move axially along the sieve body to the discharge end, achieving skin-to-powder separation. A frame 13 is connected to one end of the base 4, and a feed hopper 14 is connected to the top of the frame 13. Two crushing rollers 24 are rotatably connected to the inner wall of the feed hopper 14. Each set of crushing rollers 24 is connected to a gear 23, which mesh with each other to achieve synchronous rotation in opposite directions. A servo motor 15 is connected to the feed hopper 14, and the output end of the servo motor 15 is connected to either crushing roller 24. The top opening of the feed hopper 14 is for feeding, and the bottom outlet of the feed hopper 14 is connected to a discharge plate 16. The discharge plate 16 is inclined and extends into the feed end of the drum screen 1 at an angle of approximately 30°, allowing the crushed chili peppers to slide along the plate into the drum screen 1. The servo motor 15 drives the two crushing rollers 24 to rotate in opposite directions, crushing the chili peppers through toothed shearing and compression. The crushed mixture can slide into the feed end of the drum screen 1 through the feed plate 16. Two cantilever frames 6 are connected to the front and rear ends of the base 4 respectively; all cantilever frames 6 are detachably connected to a cleaning mechanism, which is used to clean the drum screen 1.

[0025] like Figure 2As shown, the cleaning mechanism includes a cleaning brush 19 and four cantilever frames 6 detachably connected to a mounting plate 18. The cleaning brush 19 is slidably connected to the inner wall of the mounting plate 18. Several springs 22 are connected to the inner wall of the mounting plate 18, with the other end of each spring 22 connected to the top of the cleaning brush 19. The elasticity of the springs 22 keeps the brush bristles in contact with the screen surface, removing the chili skin clogging the screen holes. The bristles of the cleaning brush 19 are in contact with the drum screen 1. The bristles are made of nylon and are arranged in long strips along the axial direction of the drum screen 1. Handles 17 are connected to both ends of the top of the mounting plate 18. Several telescopic rods 21 are connected to the inner wall of the mounting plate 18. The telescopic end of each telescopic rod 21 is connected to the top of the cleaning brush 19. The telescopic rods 21 are used to help fix the position of the cleaning brush 19 and prevent it from shifting during cleaning. The contact distance between the brush bristles and the screen surface can be automatically adjusted by the springs 22 and the telescopic rods 21. Several fixing bolts 20 are threadedly connected to the mounting plate 18 and the cantilever frames 6. The entire cleaning mechanism can be removed by simply unscrewing the bolts. Two sets of rotating shafts 11 and driving rollers 7 are provided. The two sets of rotating shafts 11 are respectively connected to pulleys 10. The two sets of rotating shafts 11 are rotatably connected to the corresponding vertical plates 8. The two sets of pulleys 10 are connected to a rotating belt 9 to form a synchronous transmission structure, ensuring that the rotation speed of the two driving rollers 7 is consistent and avoiding the skew of the drum screen 1 due to uneven force.

[0026] like Figure 1 As shown, the base 4 is connected to two fixed seats 2 at the end away from the stepper motor 12. Each fixed seat 2 is rotatably connected to a driven roller 3 through a bearing. The two driven rollers 3 are movably connected to the outer wall of the drum screen 1 to help support the weight of the drum screen 1 and reduce rotational resistance.

[0027] The specific implementation process is as follows:

[0028] In operation, chili peppers are poured into the feed hopper 14 from the top. The servo motor 15 drives the dual crushing rollers 24 to rotate synchronously and at the same speed in opposite directions. The chili peppers are crushed through toothed shearing and compression, breaking down the tough outer skin while preserving the seeds. The crushed mixture slides through the discharge plate 16 into the feed end of the drum screen 1. The stepper motor 12 drives the dual active rollers 7 to rotate via the rotating belt 9, causing the drum screen 1 to rotate. The chili pepper mixture tumbles inside the screen due to centrifugal force and friction. Because the seeds are smaller than the screen holes, they pass through the screen and fall out of the drum screen 1, while the outer skin moves axially along the screen body to the discharge end, achieving skin-material separation. As the drum screen 1 rotates, the cleaning brush 19, under the action of the spring 22, adheres tightly to the screen surface, clearing away the skin debris clogging the screen holes in the direction of screen rotation.

[0029] Operators can periodically loosen the mounting plate 18 by turning the bolts, and then remove the mounting plate 18 (i.e., the cleaning brush 19) using the handle 17 for maintenance or replacement.
