Description

Technical Field

[0001] This utility model relates to the technical field of chain conveyors, and in particular to a guiding device for a chain conveyor. Background Technology

[0002] A chain conveyor is a mechanical device that uses a chain as both a traction and load-bearing component, and achieves material transport through the continuous movement of the chain. It is widely used in industrial production for transporting various bulk materials and packaged goods. Its core structure typically includes a drive unit, tensioning device, chain, sprockets, frame, and accessories for carrying or transporting materials. The drive unit, through components such as a motor and reducer, drives the sprockets to rotate. The sprockets mesh with the chain, causing the chain to circulate along a predetermined track. The material is placed on the load-bearing components of the chain, and the conveying process from loading point to unloading point is completed as the chain moves. There are various types of chain conveyors, commonly including scraper conveyors, buried scraper conveyors, plate conveyors, and bucket elevators. They each have their own characteristics in structure and working principle to adapt to the properties of different materials and conveying requirements.

[0003] Traditional chain conveyors lack guiding devices during transport, leading to material deviation and scattering, which affects material transport and reduces their practicality. Therefore, to solve the above problems, this utility model provides a guiding device for chain conveyors. Utility Model Content

[0004] The purpose of this invention is to provide a guiding device for a chain conveyor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guiding device for a chain conveyor, comprising a chain conveyor, with threaded rods rotatably connected to both ends of the chain conveyor, a movable plate mounted on the outer ring surface of the threaded rods, a support frame mounted on the top of the movable plate, a support plate mounted on one end of the support frame, three first dampers mounted on the outside of the support plate, a support seat mounted on one end of each first damper, a guide plate mounted on one end of each support seat, a plurality of mounting grooves evenly spaced on the outer side of the guide plate, a support block mounted inside the mounting groove, and a guide roller mounted on the bottom of the support block and located on the outer side of the guide plate.

[0006] Preferably, a throttle is installed at one end of the threaded rod, and the outer ring surface of the threaded rod is threadedly connected to the interior of the movable plate.

[0007] Preferably, guide rods are installed on the outside of the chain conveyor and on both sides of the threaded rod. One end of the guide rod passes through the movable plate and extends to its outside. The outer ring surface of the guide rod is slidably connected to the inside of the movable plate.

[0008] Preferably, a fixed seat is installed on the outside of the bearing plate and on both sides of the first damper. A second damper is rotatably connected to one end of the fixed seat, and one end of the second damper is rotatably connected to the outside of the support seat.

[0009] Preferably, the outer side dimensions of the support block are adapted to the inner side wall dimensions of the mounting groove, and one end of the support block can be connected to the interior of the mounting groove.

[0010] Preferably, a plurality of fixed frames are installed at equal intervals on the top of the bearing plate, a movable rod is installed on the inner top of the fixed frame, one bottom end of the movable rod passes through the inner side of the mounting groove and connects to the inside of the support block, an elastic element is installed on the outer ring surface of the movable rod, a limit plate is installed on the outer ring surface of the movable rod and below the elastic element, and a handle is installed on one top end of the movable rod, passing through the top of the fixed frame.

[0011] In summary, this utility model has the following beneficial technical effects:

[0012] This chain conveyor's guiding device uses a throttle to rotate a threaded rod. The rotation of the threaded rod causes a movable plate to move axially along the threaded rod, thus adjusting the guide plate's position. When goods contact the guide roller and generate impact force, the first and second dampers work together to buffer the impact, further dispersing and absorbing the force and enhancing the guide roller's impact resistance. When the bottom of the movable rod is pulled out of the support block, the support block can be removed from the mounting slot. During installation, the support block is placed into the mounting slot, and the handle is released. The elastic element returns to its original shape, pushing the limit plate and movable rod downwards, allowing the bottom of the movable rod to engage with the support block, thus fixing the support block. This facilitates the disassembly and replacement of the guide roller, improving its practicality. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1 - Figure 4 The present invention will be described in further detail below.

[0019] A guiding device for a chain conveyor, referring to Figure 1 - Figure 4 The system includes a chain conveyor 1, with threaded rods 2 rotatably connected to both ends of the chain conveyor 1. A movable plate 3 is installed on the outer ring surface of the threaded rod 2. A support frame 4 is installed on the top of the movable plate 3. A support plate 5 is installed at one end of the support frame 4. Three first dampers 6 are installed on the outside of the support plate 5. A support seat 7 is installed at one end of the first damper 6. A guide plate 8 is installed at one end of the support seat 7. Several mounting slots 9 are equally spaced on the outer side of the guide plate 8. A support block 10 is installed inside the mounting slot 9. A guide roller 11 is installed at the bottom of the support block 10 and on the outside of the guide plate 8.

[0020] Reference Figure 1 - Figure 2 A handle 12 is installed at one end of the threaded rod 2. The outer ring surface of the threaded rod 2 is threadedly connected to the inside of the movable plate 3. When the position of the guide plate 8 needs to be adjusted, the handle 12 is rotated, which drives the threaded rod 2 to rotate. Since the threaded rod 2 is threadedly connected to the movable plate 3, the rotation of the threaded rod 2 will cause the movable plate 3 to move along the axial direction of the threaded rod 2. The movement of the movable plate 3 drives the support frame 4, the support plate 5, and the guide plate 8 to move, thereby realizing the adjustment of the position of the guide plate 8. Guide rods 13 are installed on the outside of the chain conveyor 1 and on both sides of the threaded rod 2. One end of the guide rod 13 passes through the movable plate 3 and extends to its outside. The outer ring surface of the guide rod 13 is slidably connected to the inside of the movable plate 3. When the movable plate 3 moves along the threaded rod 2, the guide rod 13 plays a guiding role, ensuring that the movable plate 3 can only move in a straight line along the axial direction of the guide rod 13, preventing the movable plate 3 from deflecting during the movement, thereby making the movement of the guide plate 8 more stable and accurate.

[0021] Reference Figure 3Fixed seats 14 are installed on the outside of the bearing plate 5 and on both sides of the first damper 6. A second damper 15 is rotatably connected to one end of the fixed seat 14. One end of the second damper 15 is rotatably connected to the outside of the support seat 7. When the goods come into contact with the guide roller 11 and generate impact force, the first damper 6 and the second damper 15 work together to buffer the impact. The second damper 15 is connected to the bearing plate 5 through the fixed seat 14 and rotatably connected to the support seat 7 at the other end. This can further disperse and absorb the impact force, enhance the impact resistance of the guide roller 11, and reduce the damage to the guide roller 11 caused by the impact.

[0022] Reference Figure 1 - Figure 4 The outer dimensions of the support block 10 are adapted to the inner wall dimensions of the mounting groove 9. One end of the support block 10 can be inserted into the interior of the mounting groove 9. The support block 10, installed in the mounting groove 9, can stably support the guide roller 11. When the guide roller 11 is subjected to friction or impact from the goods, the support block 10 remains relatively stable in the mounting groove 9 to ensure that the guide roller 11 can rotate normally, providing stable guidance and rolling support for the goods. Several fixed frames 16 are evenly spaced on the top of the bearing plate 5. A movable rod 17 is installed on the inner top of the fixed frame 16. One end of the bottom of the movable rod 17 penetrates into the interior of the mounting groove 9 and is inserted into the interior of the support block 10. An elastic element 18 is installed on the outer ring surface of the movable rod 17. A limiting plate 19 is installed below the elastic element 18. A handle 20 is installed at the top end of the movable rod 17, which extends to the top of the fixed frame 16. When the guide roller 11 needs to be disassembled or installed, the handle 20 is pulled upward. The handle 20 drives the movable rod 17 to move upward. The movable rod 17 drives the limiting plate 19 to compress the elastic element 18 upward. When the bottom of the movable rod 17 is pulled out from the support block 10, the support block 10 can be taken out from the mounting groove 9. During installation, the support block 10 is placed into the mounting groove 9 and the handle 20 is released. The elastic element 18 returns to its original shape and pushes the limiting plate 19 and the movable rod 17 downward, so that the bottom of the movable rod 17 is connected to the support block 10, thereby fixing the support block 10 and facilitating the disassembly and replacement of the guide roller 11.

[0023] The implementation principle of the guiding device for a chain conveyor according to this utility model embodiment is as follows: When using this device, when it is necessary to adjust the position of the guide plate 8, the handle 12 is rotated, which drives the threaded rod 2 to rotate. Since the threaded rod 2 is threadedly connected to the movable plate 3, the rotation of the threaded rod 2 will cause the movable plate 3 to move along the axial direction of the threaded rod 2. The movement of the movable plate 3 drives the support frame 4, the support plate 5, and the guide plate 8 to move, thereby realizing the adjustment of the position of the guide plate 8. When the movable plate 3 moves along the threaded rod 2, the guide rod 13 plays a guiding role, ensuring that the movable plate 3 can only move in a straight line along the axial direction of the guide rod 13, preventing the movable plate 3 from deflecting during the movement, thereby making the movement of the guide plate 8 more stable and accurate. When the goods come into contact with the guide roller 11 and generate impact force, the first damper 6 and the second damper 15 work together to buffer the impact. The second damper 15 is connected to the support plate 5 through the fixed seat 14, and the other end is rotatably connected to the support seat 7, which can further disperse and absorb the impact force and enhance the guide roller 11. The support block 10 has strong impact resistance, reducing damage to the guide roller 11 caused by impact. When the guide roller 11 is subjected to friction or impact force from the goods, the support block 10 remains relatively stable in the mounting groove 9 to ensure that the guide roller 11 can rotate normally, providing stable guidance and rolling support for the goods. When it is necessary to disassemble or install the guide roller 11, pull the handle 20 upward. The handle 20 drives the movable rod 17 to move upward. The movable rod 17 drives the limit plate 19 to compress the elastic element 18 upward. When the bottom of the movable rod 17 is pulled out from the support block 10, the support block 10 can be taken out from the mounting groove 9. During installation, the support block 10 is placed in the mounting groove 9 and the handle 20 is released. The elastic element 18 restores its deformation and pushes the limit plate 19 and the movable rod 17 downward, so that the bottom of the movable rod 17 is connected to the support block 10, thereby fixing the support block 10 and facilitating the disassembly and replacement of the guide roller 11. The external helix opening angle of the threaded rod 2 is 20 degrees, and the thread self-locking condition is calculated according to the following formula: self-locking condition = friction coefficient * tan (helix angle) ≥ 1.
