Description

Technical Field

[0001] This utility model relates to the field of chain conveyor technology, specifically a reversible chain conveyor. 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.

[0003] Authorization announcement number CN218786283U discloses a height-adjustable convenient chain conveyor, which includes a base, a U-shaped plate, and a fixed plate. Two symmetrically arranged slide rails are fixed inside the U-shaped plate, and the two slide rails are respectively located on both sides of the fixed plate. This prior art chain conveyor can only work in a single area. However, some logistics conveying systems are generally equipped with fire safety doors. In emergency situations such as when the fire safety door falls, the prior art chain conveyor will interfere with the safety door due to its limited flexibility, causing the safety door to fall only above the conveyor and unable to be closed.

[0004] In summary, existing chain conveyors cannot be deployed in cross-regional sections, resulting in limited application scenarios and necessitating improvements. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a reversible chain conveyor, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a reversible chain conveyor, comprising a frame and a support frame;

[0007] The frame is equipped with a fixed conveying section and a conveying power box. The fixed conveying section is equipped with a fixed conveying chain and a first drive shaft. The fixed conveying chain connects the first drive shaft and the conveying power box. The left end of the frame is equipped with a bearing seat. The bearing seat is equipped with a second drive shaft. The second drive shaft is equipped with a tilting conveying chain. The tilting conveying chain is rotatably connected to the tilting conveying section. The bottom left side of the tilting conveying section overlaps with the support frame. A conveying transmission chain connects the first drive shaft and the second drive shaft.

[0008] The frame is equipped with a tilting drive motor and a drive shaft. The output shaft of the tilting drive motor is connected to the drive shaft, and the drive shaft is equipped with a drive sprocket. Both sides of the outer side of the transmission shaft are rotatably connected to sprockets through bearings. A tilting transmission chain is provided between the sprockets and the drive sprocket.

[0009] Round rods are evenly arranged on the side of the two sprockets that are far apart from each other. Telescopic components are provided on the right end of the inner wall of the front and rear sides of the flipping conveyor section, and the round rods are inserted into the telescopic components.

[0010] Preferably, the telescopic assembly includes a mounting ring disposed on the flipping conveyor section, wherein an electric telescopic rod is uniformly and circumferentially disposed on the mounting ring, and a fixing block is disposed on the output end of the electric telescopic rod, and the round rod is inserted into the fixing block.

[0011] Preferably, the round rod contacts the movable block, the movable block is provided with an arc-shaped rod that passes through the mounting frame, an arc-shaped spring connects the movable block and the mounting frame, and the mounting frame is connected to the fixed block.

[0012] Preferably, the movable block has an arc-shaped groove that contacts the round rod, and the radius of the arc-shaped groove is larger than the radius of the round rod.

[0013] Preferably, the movable block is located between the fixed block and the sprocket.

[0014] Preferably, the fixed block is provided with a stop block, and the stop block is located between the mounting bracket and the movable block.

[0015] This invention provides a reversible chain conveyor. Compared with the prior art, it has the following advantages:

[0016] Beneficial effects:

[0017] 1. This reversible chain conveyor drives a fixed conveyor chain to rotate via a power box, causing a drive shaft to rotate. This, in turn, drives a second drive shaft via a conveyor chain, causing the reversible conveyor chain to rotate as well. This achieves the conveying function of a traditional chain conveyor. In emergencies such as when fire safety doors fall, the reversible drive motor can rotate the drive shaft, causing the drive sprocket to rotate via the reversible drive chain. This, in turn, drives the telescopic assembly via a round rod, causing the reversible conveyor section to rotate automatically. This allows the latter half of the conveyor to automatically rotate, avoiding falling safety doors and meeting the needs of cross-regional conveying scenarios. Therefore, this chain conveyor effectively meets the automation requirements of cross-regional conveying scenarios, providing greater flexibility for solving problems related to the arrangement of material stacks or boxes.

[0018] 2. This reversible chain conveyor, through the telescopic component, allows the fixed block to move away from the round rod, which can periodically drive the sprocket to rotate without driving the reversible conveyor section to rotate, thus avoiding the situation where the reversible drive chain rusts and gets stuck due to long-term inactivity.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] See Figures 1-4 This utility model provides the following two technical solutions:

[0026] First embodiment: A reversible chain conveyor, including a frame 7 and a support frame 8;

[0027] The frame 7 is equipped with a fixed conveyor section 1 and a conveyor power box 6. The fixed conveyor section 1 is equipped with a fixed conveyor chain and a drive shaft 9. The fixed conveyor chain is connected to the drive shaft 9 and the conveyor power box 6. The conveyor power box 6 drives the fixed conveyor chain to rotate, so that the drive shaft 9 rotates accordingly. The left end of the frame 7 is equipped with a bearing seat 10. The bearing seat 10 is equipped with a drive shaft 11. The drive shaft 11 can rotate on the bearing seat 10. The drive shaft 11 is equipped with a tilting conveyor chain. The tilting conveyor chain is rotatably connected to the tilting conveyor section 4. The bottom left side of the tilting conveyor section 4 is attached to the support frame 8. When the drive shaft 11 rotates, it can drive the tilting conveyor chain to rotate and transport the goods on it. When the tilting conveyor section 4 tilts, it can drive the tilting conveyor chain on it to tilt accordingly. A conveyor transmission chain 3 is connected between the drive shaft 9 and the drive shaft 11, so that the drive shaft 9 and the drive shaft 11 rotate synchronously to complete the conveying.

[0028] The frame 7 is equipped with a tilting drive motor 5 and a drive shaft 12. The output shaft of the tilting drive motor 5 is connected to the drive shaft 12, and the drive shaft 12 is equipped with a drive sprocket. Both sides of the transmission shaft 11 are rotatably connected to sprockets 13 through bearings. A tilting transmission chain 2 is provided between the sprockets 13 and the drive sprockets. When the tilting drive motor 5 is working, the tilting transmission chain 2 rotates and drives the sprockets 13 to rotate. Since the sprockets 13 are connected to the transmission shaft 11 through bearings, they will not drive the transmission shaft 11 to rotate. Therefore, the transmission shaft 11 will not drive the sprockets 13 to rotate during normal rotation and transmission.

[0029] In order to enable the sprocket 13 to rotate and drive the tilting conveyor section 4 to tilt, round rods 14 are evenly arranged on the side of the two sprockets 13 that are far apart from each other. Telescopic components are provided on the right end of the inner wall of the front and rear sides of the tilting conveyor section 4, and the round rods 14 are inserted into the telescopic components. In this way, when the sprocket 13 rotates, it drives the round rods 14 to rotate, which in turn drives the tilting conveyor section 4 to rotate through the telescopic components.

[0030] The transmission shaft 11 and the tilting conveyor section 4 rotate through bearings, so that the rotation of the transmission shaft 11 does not affect the tilting conveyor section 4, and the tilting conveyor section 4 does not affect the transmission shaft 11 when it tilts.

[0031] The telescopic assembly includes a mounting ring 15 disposed on the tilting conveyor section 4. Electric telescopic rods 16 are evenly arranged circumferentially on the mounting ring 15, and a fixing block 17 is disposed on the output end of the electric telescopic rods 16. A round rod 14 is inserted into the fixing block 17. The sprocket 13 drives the round rod 14 to rotate, causing the fixing block 17 to drive the electric telescopic rod 16 to rotate, thus causing the mounting ring 15 and the tilting conveyor section 4 to tilt. Normally, the tilting conveyor section 4 is not tilted, so the tilting drive chain 2 is prone to rusting and jamming if it is not operated for a long time. To avoid this, the tilting drive chain 2 needs to be operated. Therefore, the fixing block 17 can be separated from the round rod 14, which periodically drives the sprocket 13 to rotate, causing the tilting drive chain 2 to operate without rotating the tilting conveyor section 4.

[0032] The round rod 14 contacts the movable block 18, which is located between the fixed block 17 and the sprocket 13. This allows the round rod 14 to contact the movable block 18 first when it rotates. The movable block 18 has an arc-shaped groove that contacts the round rod 14, and the radius of the arc-shaped groove is larger than the radius of the round rod 14. This allows the round rod 14 to enter the arc-shaped groove and then compress the movable block 18 when it rotates. The movable block 18 is provided with an arc-shaped rod 19 that passes through the mounting frame 20. An arc-shaped spring 21 connects the movable block 18 and the mounting frame 20. The mounting frame 20 is connected to the fixed block 17. After the movable block 18 is compressed, it rotates and moves through the arc-shaped rod 19, thereby compressing the arc-shaped spring 21.

[0033] The second embodiment differs from the first embodiment in that a stop block 22 is provided on the fixed block 17, and the stop block 22 is located between the mounting bracket 20 and the movable block 18, so that when the round rod 14 pushes the movable block 18 and is blocked by the stop block 22, the round rod 14 is aligned with the fixed block 17, so that the fixed block 17 can be sleeved on the round rod 14.

[0034] When it is necessary to put the fixed block 17 back onto the round rod 14, the fixed block 17 is first moved by the electric telescopic rod 16, and then the sprocket 13 is rotated so that the round rod 14 rotates and begins to contact the movable block 18 to squeeze it. The arc spring 21 can buffer and slow down the movement of the round rod 14 to avoid excessive impact force between it and the movable block 18. When the round rod 14 squeezes the movable block 18 to the point that it is blocked by the stop block 22 and cannot rotate, the electric telescopic rod 16 continues to push the fixed block 17 to move, so that the fixed block 17 can be put onto the round rod 14.

[0035] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0036] In use, the sprocket 13 is rotated by the flip transmission chain 2, which causes the round rod 14 to rotate the fixed block 17, thereby rotating the flip conveyor section 4 to complete the flipping without blocking the closing of the safety door. When conveying, the fixed conveyor chain drives the flip conveyor chain to rotate through the first transmission shaft 9, the second transmission shaft 11 and the conveyor transmission chain 3, without affecting daily conveying.

[0038] 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.
