Description

Technical Field

[0001] This utility model relates to the field of conveying technology, and more specifically, to a high-speed circulating conveying device. Background Technology

[0002] The conveying industry is a core supporting area of ​​industrial production and logistics systems, and its technological development has a profound impact on manufacturing efficiency, resource turnover speed and production costs.

[0003] For example, CN118237883B discloses an automatic cutting device for chain processing, including a processing frame, a chain to be cut that is engaged and driven on the processing frame, and a connecting assembly that is slidably mounted on the processing frame; a second sprocket is fixed to the circumferential side of the connecting shaft; a transmission chain is engaged and driven on the second sprocket; two locking components are engaged between the chain to be cut and the transmission chain; a drive frame is located near the end of the U-shaped fixed frame; punches are slidably mounted in both guide sleeves; and a rotating component adapted to the two punches is rotatably mounted between the two fixed rings. However, this device uses a chain for transmission, requiring a carrier to be installed on the chain to transport the workpiece. Installing a carrier on the chain leads to assembly difficulties, poor stability, and increases the number of assembly components, resulting in a significant increase in weight and cost. It is also not conducive to reasonable layout and has significant limitations. Utility Model Content

The transmission assembly includes at least one set of carriers. Each carrier has a body with protrusions fixed on both sides of one end and a connecting part fixed in the middle of the other end. The connecting parts of adjacent carriers can be placed between the protrusions. A through groove is formed on both the connecting part and the protrusion, and a pin can be inserted into the through groove to pivotally connect adjacent carriers. A set of bosses are evenly distributed at equal angles on the outer circumference of the driving wheel and the driven wheel. The bosses have grooves that are adapted to the pins.

[0007] Preferably, the pin is pivotally provided with a bearing, and the boss is provided with a slot adapted to the bearing.

[0008] Preferably, the frame is further provided with an annular guide rail, and the lower surface of the bearing is always slidably connected to the upper surface of the guide rail.

[0009] Preferably, the bottom of the body is provided with a connecting block, which is integrally formed with the body and is U-shaped; each of the adjacent protrusions is provided with a bearing groove, which is designed to mimic the shape of the connecting block.

[0010] Preferably, the connecting block is further provided with a rod, and the rod is provided with a pulley, the outer circumferential surface of which can be tightly attached to the inner wall of the bearing groove.

[0012] Preferably, a set of mounting holes are formed on the upper surface of the carrier.

[0013] Preferably, a tachometer is mounted on the frame.

[0014] The beneficial effects of this utility model are mainly reflected in:

[0015] 1. The ingenious design utilizes interconnected carriers to form the transmission assembly. Compared to existing technologies that mount the carriers on belts or chains, this reduces a significant number of mechanical components, resulting in overall weight reduction and lower costs. Furthermore, the sequential delivery of pins by the bosses ensures high overall transmission precision, preventing slippage or jumping during transmission, and avoiding impacts and vibrations to guarantee smooth operation.

[0016] 2. The circular guide rail can improve the load capacity and stability of the device. In addition, the sliding connection between the bearing and the guide rail can reduce the friction between them and extend the service life.

[0017] 3. The matching of the connecting block and the bearing groove can further improve the accuracy of transmission and ensure the smoothness of operation.

[0018] 4. The pulleys reduce friction between the base, the driving wheel, and the driven wheel, thus extending service life. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 2 As shown, this utility model discloses a high-speed circulating conveying device, including a frame 1. The two ends of the frame 1 are respectively provided with a driving wheel 2 and a driven wheel. A transmission assembly is wound around the driving wheel 2 and the driven wheel. The transmission assembly includes at least a set of carriers 3 with mounting holes 36. The carrier 3 has a body 31. The two sides of one end of the body 31 are fixed with outward protrusions 32, and the middle of the other end is fixed with a connecting part 33. The connecting parts 33 of adjacent carriers 3 can be placed between the outward protrusions 32. A through groove 34 is opened on both the connecting part 33 and the outward protrusions 32. A pin 35 can be inserted into the through groove 34 to pivotally connect adjacent carriers 3. A set of bosses 21 are evenly distributed at equal angles on the outer circumferential surface of the driving wheel 2 and the driven wheel. The bosses 21 are provided with grooves 22 that are adapted to the pins 35. The above design is ingenious. The transmission assembly is formed by the interlocking of the carriers 3. Compared with the existing technology of mounting the carriers on belts or chains, it can reduce a large number of mechanical components (such as belt drive lines or chain drive lines), achieving overall weight reduction and cost reduction. At the same time, the bosses 21 deliver the pins 35 one by one, which can achieve the overall transmission accuracy of the device, ensure no slippage or jumping during transmission, and also avoid impact and vibration, ensuring smooth operation.

[0026] A bearing 4 is pivotally mounted on the pin 35, and a groove for the bearing 4 is formed on the boss 21. A circular guide rail 10 is also fixed to the frame 1, and the lower surface of the bearing 4 is always slidably connected to the upper surface of the guide rail. The circular guide rail 10 improves the load-bearing capacity and stability of the device. Furthermore, the slidable connection between the bearing and the guide rail reduces friction and extends service life.

[0027] The bottom of the main body 31 is provided with a connecting block 5, which is integrally formed with the main body 31 and is U-shaped. Each adjacent boss 21 is provided with a bearing groove 23, which is designed to mimic the shape of the connecting block 5. The matching of the connecting block 5 and the bearing groove 23 can further improve the accuracy of transmission and ensure the smoothness of operation. The connecting block 5 is also provided with a rod 51, and the rod 51 is provided with a pulley 52. ​​The outer circumferential surface of the pulley 52 can be tightly attached to the inner wall of the bearing groove 23. The setting of the pulley 52 can reduce the friction between the two and extend the service life.

[0028] A support plate 11 is fixedly mounted on the frame 1, and a drive motor 12 is fixedly mounted on the support plate 11. The motor shaft of the drive motor 12 is connected to the drive wheel 14 through a reducer 13. A transmission wheel 15 is fixedly mounted on the drive wheel 2, and a transmission belt 16 is wound between the transmission wheel 15 and the drive wheel 14. The use of the drive motor 12 utilizes its high efficiency, energy saving, fast response, wide speed range, and ease of control to greatly improve accuracy.

[0029] In this embodiment, a tachometer is installed on the frame 1 to calculate the number of rotations of the carrier in real time.
