Abstract
Description
Technical Field
[0001] This utility model relates to the field of material handling, and in particular to a feeding device for sorting equipment. Background Technology
[0002] With the increasing demand for industrial automation and precision manufacturing, sorting equipment is being used more and more widely in fields such as ores, grains, and chemical raw materials. As the core module of sorting equipment, the performance of the feeding device directly affects sorting efficiency, accuracy, and equipment stability. Currently, the belt spacing of feeding devices is usually adjusted by replacing different specifications of drive pulleys or modifying complex mechanical structures, a cumbersome and time-consuming process. For example, some equipment requires disassembling multiple sets of bolts or gears, resulting in downtime of several hours and making it impossible to quickly adapt to the sorting needs of materials with different particle sizes.
[0003] In traditional designs, the axial adjustment mechanism (such as a slide rail or screw) is directly and rigidly connected to the drive shaft, which makes the drive shaft prone to misalignment or vibration during adjustment. For example, when the belt spacing needs to be adjusted due to wear or material impact, a slight misalignment of the drive shaft may cause the belt to run off track, slip, or even lead to transmission failure, with a failure rate as high as 20%-30%. Utility Model Content
[0004] The purpose of this invention is to provide a feeding device for sorting equipment, which solves the problems of difficulty in adjusting belt spacing and conflict between axial adjustment and transmission stability in existing equipment.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A feeding device for a sorting equipment includes a support frame, with rotating shafts rotatably connected to both ends inside the support frame, a rotating cylinder slidably connected to the outer side of the rotating shafts at equal intervals, a ball block fixedly connected to the outer side of the rotating cylinder, a pulley rotatably connected to the outer side of the ball block, and a belt drive connecting the corresponding pulleys on the outer side of the two rotating shafts. An adjusting cylinder is rotatably connected to the outer side of the rotating cylinder. Sliding holes are symmetrically opened at the bottom of the support frame, and a sliding rod is fixedly connected to the bottom of the adjusting cylinder. The sliding rod vertically passes through the adjusting cylinder and extends to the bottom of the support frame. A movable plate is symmetrically slidably connected to the bottom of the support frame, and guide holes are equidistantly opened on the surface of the movable plate. The distance between adjacent guide holes increases from one end to the other end. The bottom end of the sliding rod passes through the corresponding sliding hole and guide hole in sequence and is slidably connected to the sliding hole and guide hole.
[0006] Preferably, curved protrusions are fixedly connected at equal intervals on the outer side of the ball block, and curved grooves are opened at equal intervals on the inner wall of the pulley. The curved protrusions are slidably connected to the corresponding curved grooves. Through the sliding cooperation between the curved protrusions and the curved grooves, the pulley can rotate freely around the ball block and rotate with the ball block.
[0007] Preferably, a strip-shaped groove is provided on the outer side of the rotating shaft, and a strip-shaped protrusion is provided on the inner wall of the rotating cylinder. The strip-shaped protrusion is slidably connected to the corresponding strip-shaped groove. The sliding fit between the strip-shaped protrusion and the strip-shaped groove allows the rotating cylinder to move along the axial direction of the rotating shaft, while ensuring that the rotating cylinder rotates synchronously with the rotating shaft.
[0008] Preferably, a motor is installed on one side of the bracket, and the output end of the motor is fixedly connected to the end of the rotating shaft. The motor directly drives the rotating shaft, and the dual-shaft synchronous transmission is achieved through a belt.
[0009] Preferably, the bottom of the bracket is symmetrically fixed with fixed plates, the bottom of the movable plate is fixed with a receiving plate, and the receiving plate is rotatably connected with a threaded rod. The threaded rod is threaded into the corresponding fixed plate. Through the threaded engagement between the threaded rod and the fixed plate, the movable plate is driven to slide along the bottom of the bracket, thereby adjusting the position of the sliding rod.
[0010] Preferably, a handwheel is fixedly connected to one end of the threaded rod, which is convenient for the operator to manually rotate and adjust.
[0011] Preferably, baffles are symmetrically fixedly connected to the outside of the slide rod, with the baffles located at the top of the slide hole and the bottom of the guide hole, respectively, to limit the axial displacement range of the slide rod and prevent the slide rod from coming out of the slide hole or guide hole during the adjustment process.
[0012] Preferably, the support has equidistant discharge ports on one side, and a hopper is fixed at each discharge port on one side of the support to guide the material to be output to the sorting area and reduce material spillage.
[0013] Compared with the prior art, the advantages of this utility model are as follows:
[0014] 1. This utility model, through the sliding design of the movable plate and the gradually changing spacing structure of the guide hole, can drive the slide rod to move the adjusting cylinder along the axis of the rotating shaft, thereby dynamically adjusting the spacing of adjacent belts. Without changing equipment or complicated operations, it can quickly adapt to the sorting needs of materials with different particle sizes, significantly improving the equipment's versatility and production efficiency.
[0015] 2. The rotating drum of this utility model is slidably connected to the strip groove of the rotating shaft through the strip-shaped protrusion, so as to realize free axial movement; at the same time, the ball block and the pulley are circumferentially engaged through the curved protrusion and the curved groove to ensure transmission stability. When adjusting the belt spacing, the transmission relationship between the rotating shaft and the pulley is not affected, avoiding the transmission failure problem caused by axial adjustment in the traditional structure and extending the service life of the equipment.

[0022] 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.
[0023] Please see Figures 1 to 5 This embodiment provides a feeding device for a sorting equipment, including a support 1. The two ends of the support 1 are rotatably connected to a rotating shaft 2. A rotating cylinder 3 is equidistantly slidably connected to the outside of the rotating shaft 2. A ball block 4 is fixedly connected to the outside of the rotating cylinder 3. A pulley 5 is rotatably connected to the outside of the ball block 4. The pulleys 5 corresponding to each other on the outside of the two rotating shafts 2 are connected by a belt 6. An adjusting cylinder 7 is rotatably connected to the outside of the rotating cylinder 3. The bottom of the support 1 is symmetrically provided with sliding holes 8. The bottom of the adjusting cylinder 7 is fixedly connected with a sliding rod 9. The sliding rod 9 vertically passes through the adjusting cylinder 7 and extends to the bottom of the support 1. A movable plate 10 is symmetrically slidably connected to the bottom of the support 1. The surface of the movable plate 10 is provided with guide holes 11 equidistantly. The distance between adjacent guide holes 11 increases from one end to the other end. The bottom end of the sliding rod 9 passes through the corresponding sliding hole 8 and guide hole 11 in sequence and is slidably connected with the sliding hole 8 and guide hole 11.
[0024] During feeding, the rotating shaft 2 rotates, driving the rotating drum 3 to move the ball block 4, causing the pulley 5 to rotate. The material can be continuously conveyed through the belt 6. When it is necessary to sort materials of different sizes, the movable plate 10 is driven to slide along the bottom of the support 1. The spacing of the guide holes 11 on the surface of the movable plate 10 increases from one end to the other, causing the relative position of the bottom end of the slide rod 9 in the slide hole 8 and the guide hole 11 to change. The slide rod 9 disperses or moves closer to each other with the displacement trajectory of the guide hole 11, driving the adjusting cylinder 7 and the rotating drum 3 to move axially along the rotating shaft 2. The movement of the rotating drum 3 causes the position of the corresponding pulley 5 to change, resulting in a difference in the spacing of the belts 6 on the two rotating shafts 2. The spacing of the adjacent belts 6 increases from one end to the other, and the increase is determined by the displacement of the movable plate 10. As the spacing of the adjacent belts 6 increases, the material falls into the belts 6 with the corresponding spacing according to its size during the conveying process.
[0025] Curved protrusions 12 are fixedly connected at equal intervals on the outer side of the ball block 4. Curved grooves 13 are opened at equal intervals on the inner wall of the pulley 5. The curved protrusions 12 are slidably connected to the corresponding curved grooves 13. Through the sliding cooperation between the curved protrusions 12 and the curved grooves 13, the pulley 5 can rotate freely around the ball block 4, and at the same time, the ball block 4 can drive the pulley 5 to rotate synchronously.
[0026] A strip-shaped groove 14 is provided on the outer side of the rotating shaft 2, and a strip-shaped protrusion 15 is provided on the inner wall of the rotating cylinder 3. The strip-shaped protrusion 15 is slidably connected to the corresponding strip-shaped groove 14. The sliding fit between the strip-shaped protrusion 15 and the strip-shaped groove 14 allows the rotating cylinder 3 to move axially along the rotating shaft 2, while ensuring that the rotating cylinder 3 rotates synchronously with the rotating shaft 2.
[0027] A motor 16 is installed on one side of the bracket 1. The output end of the motor 16 is fixedly connected to the end of the rotating shaft 2. The motor 16 drives the rotating shaft 2 on one side to rotate, and the dual-shaft synchronous transmission is achieved through the belt 6.
[0028] The bottom of the bracket 1 is symmetrically fixed with fixed plates 17, and the bottom of the movable plate 10 is fixedly connected with a receiving plate 18. The receiving plate 18 is rotatably connected with a threaded rod 19. The threaded rod 19 is threadedly connected to the corresponding fixed plate 17. Through the threaded engagement between the threaded rod 19 and the fixed plate 17, the movable plate 10 is driven to slide along the bottom of the bracket 1, thereby adjusting the position of the slide rod 9.
[0029] A handwheel 20 is fixedly connected to one end of the threaded rod 19, which is convenient for the operator to manually rotate and adjust.
[0030] A baffle plate 21 is symmetrically fixed to the outside of the slide rod 9. The baffle plate 21 is located at the top of the slide hole 8 and the bottom of the guide hole 11, respectively, to prevent the slide rod 9 from coming out of the slide hole 8 or the guide hole 11 during the adjustment process, and to ensure the safe operation of the equipment.
[0031] The support frame 1 has a feeding port 22 equidistantly opened on one side, and a feeding hopper 23 is fixed at each feeding port 22 on one side of the support frame 1. The feeding port 22 and the feeding hopper 23 cooperate to guide the material to be output to the sorting area.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
