Description

Technical Field

[0001] This invention relates to the field of conveyor technology, specifically a conveying mechanism for the drying production of chili products. Background Technology

[0002] In the production of chili products, the core purpose of drying chilies is to inhibit the growth of microorganisms such as mold by significantly reducing their moisture content, thereby achieving long-term preservation and maintenance. A proper drying process can effectively concentrate and lock in the capsaicin and volatile aroma substances of chilies, making their flavor and spiciness more stable and prominent. In the production of dried chili products, chilies need to be transported by a conveying mechanism.

[0003] However, the existing conveying mechanisms for drying chili products still have some shortcomings. For example, chilies are prone to uneven accumulation and uneven spreading on both sides during the conveying process, which affects the subsequent drying effect. They are also prone to rolling off during the conveying process. The matching length of the conveyor belt and the baffle is fixed. After adjustment according to the height of the feed inlet of the drying equipment, the length of the conveyor belt conveying surface exceeds the length of the baffle, which causes the blocking effect on the chilies to fail.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0005] The purpose of this invention is to provide a conveying mechanism for the drying production of chili products, so as to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveying mechanism for drying chili products, comprising a frame, a slide rail fixed inside the frame, a movable frame slidably connected to the slide rail via an electric push rod, a conveyor belt mounted on the frame and the movable frame via multiple rotating rollers, telescopic baffle assemblies mounted on both sides of the top of the frame, the baffle assemblies being connected to the movable frame via connecting plates, push rollers rotatably arranged between the baffle assemblies, two crossbeams on the top of the baffle assemblies, a sealed cavity inside the crossbeams, a magnetic block slidably connected inside the sealed cavity via a spring seal, a guide rod fixedly connected to the bottom of the crossbeams, an I-shaped groove on the end face of the guide rod, the bottom walls of the lower two sides of the I-shaped groove having a wavy structure, a suction block sliding at the upper end inside the I-shaped groove, a connecting rod slidably embedded in the bottom of the suction block via a spring, the connecting rod slidingly abutting against the wavy bottom wall of the I-shaped groove via abutments on the left and right sides, and a scraper fixed at the bottom of the connecting rod; A pneumatic assembly is provided between the push roller and the cross frame, and the pneumatic assembly is used to drive the scraper to move.

[0007] Preferably, the plurality of rotating rollers include a drive roller, a plurality of support rollers, two first tension rollers and two second tension rollers. The drive roller, the plurality of support rollers and the two first tension rollers are all rotatably connected to the frame, and the two second tension rollers are rotatably connected to the moving frame. The drive roller is driven by a motor.

[0008] Preferably, the outer wall of the push roller is provided with a plurality of L-shaped push plates arranged in a circumferential array, and the rotating shaft of the push roller is connected to the drive roller by a belt and a pulley.

[0009] Preferably, the baffle assembly includes fixed baffles fixed to both sides of the top of the frame, the push roller is rotatably connected between the two fixed baffles, and a sliding baffle is slidably connected to each of the two fixed baffles. Each sliding baffle is connected to the movable frame through a connecting plate, and a top rod is rotatably connected between the side walls of the two connecting plates. The top rod abuts against the conveyor belt.

[0010] Preferably, one of the crossbeams is fixed to two fixed baffles, and the other crossbeam is fixed to two sliding baffles. The sealing cavities inside the two crossbeams are opposite to each other, and the two scrapers are staggered on both sides of the top of the conveyor belt.

[0011] Preferably, the pneumatic assembly includes two piston cylinders mounted on the outer walls of two fixed baffles. Each piston cylinder has a piston slidably connected to it by a spring. Each piston has a rod fixed on one side. Each piston cylinder has a port one and a port two at one end of its rodless chamber. The two ports one are respectively connected to the interior of the two sealed chambers through hoses. One end of each of the two ports two is connected to a regulating valve.

[0012] Preferably, the pneumatic assembly further includes two cams and two abutment plates. The two cams are respectively fixed to the outer sides of the front and rear shafts of the push roller, and the two abutment plates are respectively fixed to one end of the two piston rods. The two cams slide against the two abutment plates respectively.

[0013] Compared with the prior art, the beneficial effects of the present invention are: By setting up pneumatic components, magnetic blocks, scrapers, and I-shaped grooves with wavy bottom walls, the rotation of the push roller drives the cam to press the stopper rod, forcing gas into the sealed cavity to drive the magnetic blocks to reciprocate. The magnetic force drives the scraper to move horizontally, while the I-shaped grooves with wavy bottom walls cause the scraper to vibrate up and down, forming a compound motion of horizontal reciprocating and vertical vibration. This ensures that the chili peppers are evenly spread on the conveyor belt, and moderate compaction prevents the material from rolling off, thus improving the conveying quality.

[0014] By setting up a length adjustment mechanism consisting of a moving frame, a second tension roller, and a baffle assembly, the working length of the conveyor belt can be flexibly adjusted. When the electric push rod pushes the moving frame to move the second tension roller, the connecting plate drives the sliding baffle to extend and retract synchronously, so that the length of the baffle is always consistent with the conveying surface. At the same time, the top rod moves with the moving frame to flatten the inclined section of the conveyor belt, effectively preventing the peppers from leaking and improving the equipment's adaptability to different drying equipment.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1 to 8This invention provides a technical solution: a conveying mechanism for drying chili products. The conveying mechanism includes a frame 1, a slide rail 2 fixed inside the frame 1, and a movable frame 4 slidably connected to the slide rail 2 via an electric push rod 3. A conveyor belt 6 is mounted on the frame 1 and the movable frame 4 via multiple rotating rollers 5. The electric push rod 3 pushes the movable frame 4, causing the conveying surface of the conveyor belt 6 to extend. Telescopic baffle assemblies 7 are installed on both sides of the top of the frame 1. The baffle assemblies 7 are connected to the movable frame 4 via connecting plates 8. When the movable frame 4 slides outward, it causes the baffle assemblies 7 to extend, thus maintaining the same length as the conveying surface of the conveyor belt 6. Push rollers 9 are rotatably arranged between the baffle assemblies 7. When conveying chili peppers, the push rollers 9 ensure that the height of the chili peppers is lower than that of the baffle assemblies 7. Two crossbeams 10 are provided on the top of the baffle assemblies 7. Each crossbeam 10 has a sealed cavity 11 inside, and the sealed cavity 11 is slidably connected by a spring seal. There is a magnetic block 12 with strong magnetism. A guide rod 13 is fixedly connected to the bottom of the cross frame 10. The end face of the guide rod 13 has an I-shaped groove 14. The bottom walls on both sides of the lower end of the I-shaped groove 14 have a wave-shaped structure. A suction block 15 slides inside the upper end of the I-shaped groove 14. When the magnetic block 12 slides inside the sealed cavity 11, it drives the suction block 15 to slide in the I-shaped groove 14 through magnetic force. A connecting rod 16 is slidably embedded in the bottom of the suction block 15 through a spring. The connecting rod 16 is connected to the left and right abutment rods 1. 7 slides against the wavy bottom wall of the I-shaped groove 14. The bottom of the connecting rod 16 is fixed with a scraper 18. When the suction block 15 slides in the I-shaped groove 14, it drives the scraper 18 to move synchronously through the connecting rod 16. The left and right movement of the scraper 18 makes the peppers evenly spread on both sides of the conveyor belt 6. The sliding contact between the abutment rod 17 and the wavy bottom wall of the I-shaped groove 14 drives the connecting rod 16 to move up and down, which in turn drives the scraper 18 to shake up and down, and appropriately compacts the peppers spread on the conveyor surface of the conveyor belt 6. A pneumatic assembly 19 is provided between the push roller 9 and the cross frame 10. The pneumatic assembly 19 is used to drive the scraper 18 to move.

[0019] The multiple rotating rollers 5 include a drive roller 51, multiple support rollers 52, two first tension rollers 53 and two second tension rollers 54. The drive roller 51, multiple support rollers 52 and two first tension rollers 53 are all rotatably connected to the frame 1. The two second tension rollers 54 are rotatably connected to the moving frame 4. The drive roller 51 is driven by a motor. When the moving frame 4 moves, it drives the two second tension rollers 54 to move, which is used to adjust the length of the conveyor belt 6.

[0020] Multiple L-shaped push plates are arranged in a circumferential array on the outer wall of the push roller 9. The rotating shaft of the push roller 9 is driven by the drive roller 51 through a belt and pulley. The push roller 9 rotates in the opposite direction to the conveyor belt 6, and pushes the excessively piled peppers flat through the L-shaped push plates on its outer wall.

[0021] Specifically, during the drying process of chili products, when it is necessary to adjust the conveying mechanism according to the feeding height of the drying equipment, the electric push rod 3 pushes the moving frame 4 to slide along the slide rail 2. When the moving frame 4 moves, it drives the two second tension rollers 54 to move. During this process, the second tension roller 54 on the left side of the moving frame 4 relaxes the inner side of the conveyor belt 6, and the second tension roller 54 on the right side of the moving frame 4 tensions the conveyor belt 6 to the outside, thereby extending the conveying surface of the conveyor belt 6. When chili peppers are conveyed on conveyor belt 6, the rotating shaft of push roller 9 is driven by belt and pulley to drive drive roller 51, so that push roller 9 rotates in the opposite direction to conveyor belt 6. The L-shaped push plate on its outer wall pushes down the chili peppers that are piled up too high, so that the pile height of chili peppers is lower than that of baffle assembly 7, preventing chili peppers from falling from both sides of baffle assembly 7. At the same time, the magnetic block 12 inside the cross frame 10 slides back and forth along the sealed cavity 11 under the drive of pneumatic assembly 19. The magnetic block 12 drives the suction block 15 to slide in the I-shaped groove 14 through magnetic attraction, which in turn drives the connecting rod 16 and scraper 18 at the bottom of suction block 15 to move synchronously. The left and right movement of scraper 18 makes the chili peppers evenly spread on both sides of conveyor belt 6. At the same time, the sliding contact between the abutment rod 17 and the wavy bottom wall of I-shaped groove 14 drives the connecting rod 16 to move up and down, which in turn drives scraper 18 to shake up and down, properly compacting the chili peppers spread on the conveyor surface of conveyor belt 6, preventing unstable accumulation and rolling.

[0022] Please see Figures 9 to 10 The baffle assembly 7 includes fixed baffles 71 fixed on both sides of the top of the frame 1. The push roller 9 is rotatably connected between the two fixed baffles 71. Sliding baffles 72 are slidably connected to both fixed baffles 71. Each sliding baffle 72 is connected to the moving frame 4 through the connecting plate 8. When the moving frame 4 slides outward, it drives the sliding baffle 72 to slide along the fixed baffle 71, so that the extension length of the sliding baffle 72 can be adjusted with the movement of the moving frame 4, so that it is consistent with the length of the conveying surface of the conveyor belt 6, and avoids the two sides of the extended part of the conveyor belt 6 from losing their cover. A top rod 20 is rotatably connected between the side walls of the two connecting plates 8. The top rod 20 abuts against the conveyor belt 6. When the conveying surface of the conveyor belt 6 extends, the top rod 20 moves with the moving frame 4 and flattens the conveyor belt 6 within its movement range, so as to prevent the tilt of the conveyor belt 6 from increasing and causing a gap between it and the sliding baffle 72.

[0023] One of the crossbeams 10 is fixed to two fixed baffles 71, and the other crossbeam 10 is fixed to two sliding baffles 72 and can move with the sliding baffles 72, so as to adapt to the length change of the conveyor belt 6. The sealed cavities 11 inside the two crossbeams 10 are opened opposite each other, and two scrapers 18 are staggered on both sides of the top of the conveyor belt 6. The reciprocating stroke of the scraper 18 is halved by the two staggered scrapers 18.

[0024] Specifically, when the moving frame 4 is in the retracted state, due to the height difference between the second tension roller 54 and the support roller 52 on the right side of the moving frame 4, there is a section of inclined surface on the conveyor belt 6. This inclined surface is blocked by the sliding baffle 72 and the connecting plate 8. When the moving frame 4 extends the second tension roller 54, the length of the inclined surface on the conveyor belt 6 increases at this point. The increased inclined surface is lower than the sliding baffle 72. At this time, the push rod 20 moves synchronously with the moving frame 4 to flatten the newly added inclined surface of the conveyor belt 6, making it higher than the bottom wall of the sliding baffle 72, thus avoiding gaps. At the same time, the movement of the sliding baffle 72 moves a crossbeam 10, which reduces the overlapping area of ​​the two scrapers 18 in the conveying direction of the conveyor belt 6, increases the coverage length of the scrapers 18, and thus can adapt to changes in the length of the conveying surface of the conveyor belt 6.

[0025] Please see Figures 11 to 14 The pneumatic assembly 19 includes two piston cylinders 191 mounted on the outer walls of two fixed baffles 71. Each piston cylinder 191 has a piston slidably connected to it by a spring. Each piston has a rod 192 fixed on one side. Each piston cylinder 191 has a port 193 and a port 194 at one end of its rodless chamber. The two ports 193 are connected to the interior of two sealed chambers 11 through hoses. By pressing the gas inside the piston cylinder 191 into the sealed chamber 11, the magnetic block 12 is pushed to slide, thereby driving the scraper 18 to move. One end of each port 194 is connected to a regulating valve. The operator can open and close the regulating valve to charge and release gas to adjust the gas pressure inside the piston cylinder 191.

[0026] The pneumatic assembly 19 also includes two cams 195 and two abutment plates 196. The two cams 195 are respectively fixed on the outer side of the front and rear shafts of the push roller 9, and the two abutment plates 196 are respectively fixed on one end of the two piston rods 192. The two cams 195 slide against the two abutment plates 196 respectively. When the cams 195 rotate, they abut against the abutment plates 196, thereby driving the piston rods 192 and the piston to move, and forcing the gas inside the piston cylinder 191 into the sealed cavity 11.

[0027] Specifically, when the resistance between the cam 195 and the contact plate 196 is enhanced, it drives the piston rod 192 and the piston to move, pressurizing the gas inside the piston cylinder 191 into the sealed cavity 11 and pushing the magnetic block 12 to slide, thereby driving the scraper 18 to move. When the resistance between the cam 195 and the contact plate 196 is weakened, the piston rod 192 and the piston are reset by the spring force. This cycle realizes the reciprocating movement of the piston rod 192 and the piston, thereby driving the scraper 18 to move left and right, spreading the chili peppers evenly on the conveyor belt 6. At the same time, the rotating shaft of the push roller 9 and the drive roller 51 are driven by a belt and pulley, so that the movement frequency of the scraper 18 can change with the conveying speed of the conveyor belt 6.

[0028] Working principle: When the length of the conveying mechanism needs to be adjusted, the electric push rod 3 is activated to push the moving frame 4 to slide along the slide rail 2. The moving frame 4 drives the second tension roller 54 to move. The second tension roller 54 on the left side of the moving frame 4 relaxes the inner side of the conveyor belt 6, and the second tension roller 54 on the right side of the moving frame 4 tensions the conveyor belt 6 to the outside, thereby lengthening the conveying surface of the conveyor belt 6. At the same time, the moving frame 4 drives the sliding baffle 72 to extend synchronously through the connecting plate 8 to ensure that the length of the baffle is always matched with the conveying surface. When the push rod 20 moves with the moving frame 4, it flattens the newly added inclined section of the conveyor belt 6, eliminates the gap formed between it and the sliding baffle 72, and prevents materials from falling from the gap of the sliding baffle 72.

[0029] During the conveying process, the drive roller 51 drives the push roller 9 to rotate in the opposite direction via belt drive. The L-shaped push plate on it flattens the excessively high pile of chili peppers. At the same time, the two cams 195 on the outer side of the front and rear shafts of the push roller 9 press the abutment plate 196 and drive the stop rod 192 to move, forcing the gas in the piston cylinder 191 into the sealed cavity 11. The air pressure pushes the magnetic block 12 to slide back and forth in the sealed cavity 11. Through the magnetic force, the suction block 15 moves along the I-shaped groove 14. The contact force between the cam 195 and the abutment plate 196 gradually increases and then decreases, and this cycle continues, thereby driving the suction block 15, the connecting rod 16 and the scraper 18 to move back and forth, evenly spreading the chili peppers on the conveyor belt 6. During this process, the abutment rod 17 interacts with the wavy bottom wall of the I-shaped groove 14, causing the connecting rod 16 to drive the scraper 18 to vibrate up and down, achieving appropriate compaction of the chili pepper layer.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
