Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to an internal circulation material conveying and sprinkling device. Background Technology

[0002] In the food processing industry, especially in the production of fried foods, the methods of material conveying and feeding have a direct impact on product quality. Currently, mesh conveyor systems are commonly used in frying production lines.

[0003] While continuous material transport via a mesh conveyor system is possible, the material enters the fryer in a stable state without acceleration, preventing the formation of irregular scalloped edges. These irregular edges are a key factor in determining the texture of fried foods; without them, the texture is monotonous and fails to meet diverse consumer demands for flavor. Furthermore, some production lines use conventional bucket elevators, which dispense material by tilting the buckets at bends. However, this method often results in the material being thrown upwards at an angle, causing splashing, wasting material, and potentially affecting the cleanliness and normal operation of the production line. To address these issues, this application proposes an internal circulation material conveying and dispensing device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an internal circulation material conveying and sprinkling device. The circulating chain is evenly arranged with tilting buckets, and the bucket body and the tilting shaft have a certain eccentric distance, which achieves the effect of tilting and accelerating. The material hopper's running trajectory at the end of the conveying process is consistent with the human hand movement, maximizing the satisfaction of production process requirements.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An internal circulation material conveying and spreading device includes two frames arranged front and rear, with multiple connecting frames fixedly connected to both frames. A motor is located on the front of the front frame, and a reducer is connected to the output end of the motor. A transmission rod is fixedly connected to the output end of the reducer, and two drive sprockets are fixedly connected to the outer wall of the transmission rod. Three driven sprockets are rotatably connected to the opposite ends of the two frames. A chain is fitted on the outer walls of the three driven sprockets and the outer walls of the drive sprockets. Multiple connecting rods distributed at equal intervals are fixedly connected to the two chains, and a tilting hopper is fixedly connected to each connecting rod. A tensioning mechanism is provided on each frame.

[0007] Preferably, the tightening mechanism includes a rotating plate rotatably connected to the frame, a fixing plate fixedly connected to the side wall of the rotating plate, a pressure plate fixedly connected to the bottom of the fixing plate, a screw rotatably connected to the top of the frame, and a nut threadedly connected to the screw on its outer wall.

[0008] Preferably, the right ends of the two frames are fixedly connected to a fixed cover, the front end of the fixed cover is fixedly connected to a protective cover, the motor and reducer are disposed inside the protective cover and fixedly connected to its inner wall, and the transmission rod passes through the two frames and the protective cover and is rotatably connected to them.

[0009] Preferably, the bottom of the pressure plate is a smooth arc shape, the bottom of the pressure plate abuts against the outer wall of the chain, a limiting groove is formed at the bottom of the pressure plate, and the chain is located in the limiting groove.

[0010] Preferably, the rotating plate has a through opening, the screw passes through the through opening, and the through opening is a straight groove.

[0011] Preferably, the bottom of the frame is fixedly connected to two support legs, and each support leg is equipped with a locking caster wheel at its bottom.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 An internal circulation material conveying and spreading device includes two frames 1 arranged front and back. The frames 1 provide the installation foundation and structural support for the entire device. Multiple connecting frames 2 are fixedly connected to the two frames 1, which firmly connect the two frames 1 and enhance the stability of the overall structure of the device. Two support legs are fixedly connected to the bottom of the frames 1. The support legs support the frames 1 and keep the device at a stable working height. Each support leg is equipped with a locking caster at the bottom. The locking caster facilitates the overall movement of the device, and the locking function can fix the device in position during operation.

[0023] A motor 5 is mounted on the front of the front frame 1, providing power for the equipment. A reducer 6 is connected to the output of the motor 5, adjusting its speed and torque to better suit the equipment's operating requirements. A fixed cover 4 is fixedly connected to the right ends of both frames 1, protecting the internal and nearby components. A protective cover 3 is fixedly connected to the front of the fixed cover 4, protecting the motor 5 and reducer 6 from external interference. The motor 5 and reducer 6 are housed within the protective cover 3 and fixedly connected to its inner wall. A transmission rod 8 is fixedly connected to the output of the reducer 6, transmitting power from the reducer 6 to other components. The transmission rod 8 passes through both frames 1 and the protective cover 3, rotatably connecting to them. Two drive sprockets 7 are fixedly connected to the outer wall of the transmission rod 8, rotating synchronously with it to power the chain 10. Three driven sprockets 9 are rotatably connected to the opposite ends of both frames 1. The sprocket 9 cooperates with the drive sprocket 7 to jointly support the chain 10 and guide its transmission direction. The chain 10 (two driven sprockets on the upper side and one driven sprocket on the lower side, forming a closed transmission path with the drive sprocket, with a chain wrap angle ≥120° to ensure transmission efficiency) is mounted on the outer walls of the three driven sprockets 9 and the outer wall of the drive sprocket 7. The chain 10 circulates under the action of the drive sprocket 7 and the driven sprockets 9, driving the connecting rod 11 and the tilting hopper 12 to move. The two chains 10 are fixedly connected together. There are multiple connecting rods 11 distributed at equal intervals. The connecting rods 11 connect the two chains 10 and provide a mounting carrier for the tilting hopper 12. Each connecting rod 11 is fixedly connected to the tilting hopper 12. The tilting hopper 12 is used to carry materials and to scatter the materials during the movement. The tilting hopper 12 is connected to the connecting rods 11. When it moves to the feeding end, the tilting hopper 12 is tilted due to the angle of the lower left side of the frame 1. At the same time, the linear speed of the circulating chain gives the materials the kinetic energy to be scattered.

[0024] Each frame 1 is equipped with a tensioning mechanism, which adjusts the tension of the chain 10 to ensure the stability of the chain 10 transmission. The tensioning mechanism includes a rotating plate 13 rotatably connected to the frame 1. The rotating plate 13 can rotate around the connection point with the frame 1, providing a base for adjusting the position of the pressure plate 15. A fixing plate 14 is fixedly connected to the side wall of the rotating plate 13, connecting the rotating plate 13 and the pressure plate 15 to achieve force transmission. The pressure plate 15 is fixedly connected to the bottom of the fixing plate 14. The pressure plate 15 adjusts the tension of the chain 10 by abutting against it. The bottom of the pressure plate 15 is a smooth arc shape, and the bottom of the pressure plate 15 abuts against the outer wall of the chain 10. A limit groove is formed at the bottom of the pressure plate 15, and the chain 10 is positioned within the limit groove. The limit groove can... The chain 10 is positioned to prevent it from deviating from the pressure plate 15 during adjustment. A screw 16 is rotatably connected to the top of the frame 1. The rotation of the screw 16 can move the nut 17, thereby adjusting the position of the rotating plate 13. A through-hole 18 is provided on the rotating plate 13 (the through-hole 18 is 5-10cm long, ensuring that the rotating plate 13 can rotate ±15 degrees around the connection point). The screw 16 passes through the through-hole 18, which is a straight slot. The through-hole 18 provides space for the screw 16 to pass through. The straight slot design facilitates the rotation adjustment of the rotating plate 13. The outer wall of the screw 16 is fitted with a nut 17 that is threadedly connected to it. The nut 17 cooperates with the screw 16. By tightening or loosening, the position of the rotating plate 13 can be fixed or adjusted, thereby controlling the pressure of the pressure plate 15 on the chain 10.

[0025] In this invention, the motor 5 drives the transmission rod 8 to rotate, which in turn drives two active sprockets 7, multiple driven sprockets 9, and two chains 10 to drive the entire circulating chain. Multiple dedicated tilting hoppers 12 are evenly spaced along the entire circular chain. Workers place materials on the upper side of the tilting hoppers 12. When the materials travel with the tilting hoppers 12 to the feeding end (lower left corner), the tilting speed of the hoppers 12 is accelerated due to their larger radius of rotation, thus quickly throwing the materials downwards. This achieves a human-like manipulation of the materials, allowing them to be thrown downwards from the conveyor line.
