Description

Technical Field

[0001] This utility model relates to the field of conveyors, and in particular to a chain conveyor and a special stopper for the accumulation chain. Background Technology

[0002] Chain conveyors are conveyors that use chains for traction and load-bearing, or use slats, metal mesh belts, and rollers mounted on the chains to carry materials. They can be classified into chain type, chain plate type, chain mesh type, and slat type, etc. They are often combined with other conveyors and lifting devices to form production lines with various functions, such as painting production lines. In existing painting production lines, the engine is transferred between processes via an accumulating chain. After the product is suspended by a hanger, it moves forward with the fast and slow speed of the accumulating chain. The chain does not stop during production. Between processes, the workpiece is stopped by a stop device. After the operation of a process is completed, the stop device is manually controlled to release the workpiece.

[0003] When the stacking chain is in motion, it is exposed to the air and easily accumulates dust and impurities, which can affect its movement over time.

[0004] Therefore, it is necessary to propose a chain conveyor and a dedicated stopper for the accumulation chain to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a chain conveyor and a special stopper for the accumulation chain, so as to solve the problem that when the accumulation chain is in motion and transportation, dust and impurities easily adhere to it because the accumulation chain is exposed to the air, which easily affects the movement of the accumulation chain as the usage time increases.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a chain conveyor, including rotating gears, four rotating gears, a conveyor chain connected to the outside of the four transmission gears, a limit plate fixed to the outside of the conveyor chain, and limit holes provided on the limit plate;

[0007] A connecting frame is fixed at the top of the conveyor chain, and a movable wheel is rotatably connected to the connecting frame. An annular frame is provided above the conveyor chain, and a sliding groove is provided on the outer side of the annular frame. The movable wheel slides inside the sliding groove.

[0008] Preferably, the bottom ends of the four rotating gears are connected to support columns, and the rotating gears are rotatably connected to the corresponding support columns.

[0009] Preferably, multiple connecting frames and movable wheels are provided, and the multiple connecting frames are distributed along the length direction of the conveyor chain.

[0010] This utility model also discloses a special stopper for accumulation chain, including an auxiliary rod. The auxiliary rod is disposed on one side of the conveyor chain. A drive box is fixed at the top of the auxiliary rod. A drive motor is fixed inside the drive box. The drive shaft of the drive motor extends out of the drive box, and the extended end is connected to a support plate. An electric push rod is fixed on the support plate. A cleaning sponge sleeve is sleeved on the outside of the electric push rod.

[0011] Preferably, the top end of the electric push rod extends into the corresponding limiting hole.

[0012] Preferably, the outer side of the cleaning sponge sleeve and the outer side of the conveyor chain are in contact with each other.

[0013] Preferably, there are two electric push rods, which are located on both sides of the conveyor chain.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In the actual operation of this utility model, by stopping the gear motor, the conveyor chain is slowly stopped. After the conveyor chain drives the limit plate to the position of the electric push rod, the electric push rod is started, causing it to rise and extend into the interior of the limit hole to complete the fixation, thus completely stopping the conveyor chain.

[0016] 2. When the electric push rod retracts downwards, the conveyor chain can continue to move by starting the gear motor. At this time, after the electric push rod and the limit plate are misaligned, the electric push rod continues to rise, so that the cleaning sponge sleeve and the side of the conveyor chain come into contact. Then, by starting the drive motor, the electric push rod and the cleaning sponge sleeve can be rotated, thereby cleaning the moving conveyor chain and reducing the impact of dust and impurities on the conveyor chain.

[0017] 3. A sliding groove is provided on the outer side of the ring frame. The movable wheel slides inside the sliding groove. When the movable wheel moves in the sliding groove, the conveyor chain can move more stably and provide support for the conveyor chain. Attached Figure Description

[0023] This utility model provides, for example Figures 1-4 The chain conveyor shown includes four rotating gears 4. A conveyor chain 14 is connected to the outside of the four rotating gears 4. A limit plate 8 is fixed to the outside of the conveyor chain 14, and a limit hole 9 is opened on the limit plate 8. The conveyor chain 14 can rotate outside the fourth rotating gear 4. A hook can be installed at the bottom end of the conveyor chain 14, and the suspended object can be moved by the hook.

[0024] A gear motor can be connected to the top of one of the rotating gears 4. The drive shaft of the gear motor can be fixed to the inner ring of the corresponding rotating gear 4. The gear motor drives the rotating gear 4 to rotate, and the rotating gear 4 drives the conveyor chain 14 to rotate.

[0025] To address the issue that dust and impurities easily accumulate on the conveyor chain during transport due to its exposure to air, which can affect its movement over time, a connecting frame 10 is fixed to the top of the conveyor chain 14. A movable wheel 11 is rotatably connected to the connecting frame 10. An annular frame 1 is positioned above the conveyor chain 14, and a sliding groove 2 is formed on the outer side of the annular frame 1. The movable wheel 11 slides within the sliding groove 2. By moving the movable wheel 11 within the sliding groove 2, the movement of the conveyor chain 14 becomes more stable, and the conveyor chain 14 is provided with support.

[0026] Four rotating gears 4 are connected to support columns 3 at their bottom ends, and the rotating gears 4 are rotatably connected to the corresponding support columns 3. The support columns 3 are used to support the four rotating gears 4, and the four rotating gears 4 are arranged in a rectangle, with the four rotating gears 4 located at the four corners of the rectangle.

[0027] Multiple connecting frames 10 and moving wheels 11 are provided. Multiple connecting frames 10 are distributed along the length of the conveyor chain 14. By providing multiple connecting frames 10, the support of the conveyor chain 14 can be made more stable and the support strength can be improved.

[0028] This utility model also discloses a special stopper for an accumulation chain, including an auxiliary rod 5. The auxiliary rod 5 is disposed on one side of the conveyor chain 14. A drive box 6 is fixed to the top of the auxiliary rod 5. A drive motor 7 is fixed inside the drive box 6. The drive shaft of the drive motor 7 extends out of the drive box 6, and the extended end is connected to a support plate. An electric push rod 12 is fixed on the support plate. A cleaning sponge sleeve 13 is sleeved on the outside of the electric push rod 12. The top of the electric push rod 12 extends into the corresponding limiting hole 9.

[0029] Clean the outer side of the sponge sleeve 13 and the outer side of the conveyor chain 14 so that they fit together.

[0030] In the actual operation of this utility model, by stopping the gear motor, the conveyor chain 14 is slowly stopped. After the conveyor chain 14 drives the limiting plate 8 to the position of the electric push rod 12, the electric push rod 12 is started, causing it to rise and extend into the interior of the limiting hole 9 to complete the fixation, thus completely stopping the conveyor chain 14.

[0031] When the electric push rod 12 retracts downwards, the gear motor can be started to make the conveyor chain 14 continue to move. At this time, after the electric push rod 12 and the limit plate 8 are misaligned, the electric push rod 12 continues to rise, so that the cleaning sponge sleeve 13 and the side of the conveyor chain 14 come into contact. Then, by starting the drive motor 7, the electric push rod 12 and the cleaning sponge sleeve 13 can be driven to rotate, thereby cleaning the moving conveyor chain 14 and reducing the impact of dust and impurities on the conveyor chain 14.

[0032] There are two electric push rods 12, which are located on both sides of the conveyor chain 14. It should be noted that there are two drive motors 7 inside the drive box 6 that are connected to the corresponding electric push rods 12, which can clean both sides of the conveyor chain 14 respectively.
