Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, specifically relating to a multi-station cycloidal winding device, which is particularly suitable for automated winding operations of optical cables, electrical cables and other wires. Background Technology

[0002] Cables (including optical cables and electrical cables) require winding and unwinding on reels in industrial and daily applications. Their neat arrangement directly affects their lifespan and operational efficiency. Cables have many uses, primarily for control installation, equipment connection, and power transmission. Cables are typically used in conjunction with cable winding devices, which wind the cable onto a reel. A winding device is needed to ensure the neat arrangement of the cables during winding and unwinding.

[0003] Traditional cycloidal winding devices mostly adopt a single-station design, using mechanical transmission to achieve reciprocating cable arrangement. However, they have the following problems: 1. Complex structure: Traditional devices rely on multi-stage gear or cam transmission, resulting in large size and difficult maintenance; 2. Limited efficiency: The single-station design is difficult to adapt to the needs of simultaneous operation of multiple drums, and the cable arrangement speed and winding speed are difficult to match precisely; 3. Poor versatility: Existing devices are difficult to flexibly adjust the number of stations and the arrangement spacing, and cannot adapt to different specifications of cables or drums.

[0004] To address the aforementioned issues, this invention proposes a multi-station cycloidal device that, through the cooperation of a drive shaft and a spiral groove hole, transforms rotational motion into synchronous reciprocating motion across multiple stations, significantly improving cable arrangement efficiency and device adaptability. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a multi-station cycloidal device that, through the cooperation of the drive shaft and the spiral groove hole, transforms the rotational motion into multi-station synchronous reciprocating motion, significantly improving the cable arrangement efficiency and device adaptability.

The guide pin is embedded in the reciprocating helical groove and connected to the guide block, thereby driving the guide block and the upper and lower guide wheel assembly to reciprocate left and right.

[0010] Further specified, the lead P of the reciprocating helical groove hole on the drive shaft satisfies P = V1 / V2, where V1 is the single-stroke speed of the upper and lower guide wheel sets, and V2 is the rotational speed of the drive shaft.

[0028] like Figure 1As shown, a multi-station cycloidal winding device of this utility model includes a drive shaft 1, a sprocket 2, a mounting base 3, a bearing with a seat 4, a guide shaft 5, upper and lower guide wheel assemblies 6, a flange linear bearing 7, a guide block 8, a winding reel 9, a reduction motor 10, a cable 11, a chain 12, and a winding roller 14.

[0029] The geared motor 10 is connected to the chain 12 via a transmission gear on its drive shaft. The chain 12 is connected to the winding roller 14. The winding roller 14 is connected to the winding reel 9. The winding reel 9 is provided with multiple sets of cables 11.

[0030] The sprocket 2 is connected to the winding roller 14 and the reduction motor 10 via the chain 12. The drive shaft 1 is connected to the sprocket 2. The top of the guide block 8 is provided with a mounting groove 13. The drive shaft 1 passes through the mounting groove 13, the mounting seat 3 and the seated bearing 4 in sequence. The seated bearing 4 is fixedly connected to the side wall of the mounting seat 3. The guide shaft 5 is fixedly connected to the mounting seat 3. The flange linear bearing 7 is embedded in the guide block 8 and is connected to the guide shaft 5. The surface of the drive shaft 1 is provided with a reciprocating spiral groove with adjustable lead. A guide pin is provided in the reciprocating spiral groove and is embedded in the reciprocating spiral groove and connected to the guide block 8, thereby driving the guide block 8 and the upper and lower guide wheel assembly 6 to reciprocate left and right.

[0031] In the practical application of this embodiment, the lead P of the reciprocating helical groove hole on the transmission shaft 1 satisfies P = V1 / V2, where V1 is the single-stroke speed of the upper and lower guide wheel assembly 6 and V2 is the rotational speed of the transmission shaft 1.

[0032] In the practical application of this embodiment, the guide block 8 is slidably connected to the guide shaft 5 via a flange linear bearing 7. This structural design reduces reciprocating frictional resistance.

[0033] In the practical application of this embodiment, the winding reel 9 is provided with at least three independent workstations, each of which is provided with a cable 11. The cables 11 of each independent workstation are arranged synchronously through the upper and lower guide wheel groups 6.

[0034] In the practical application of this embodiment, the upper and lower guide wheel group 6 includes symmetrically arranged upper and lower rollers for limiting and guiding the cable 11.

[0035] In the practical application of this embodiment, the upper and lower guide wheel groups 6 are provided in at least three groups, which are arranged synchronously with the cables 11 of at least three independent workstations of the winding disc 9.

[0036] In practical applications of this embodiment, the lead of the reciprocating spiral groove is dynamically adjusted according to the diameter of the cable 11 and the winding speed. This structural design can adapt to different operational requirements.

[0037] The working principle of this utility model is as follows:

[0038] The drive shaft 1 is used to transmit torque. The sprocket 2 is connected to the geared motor 10 via a chain to realize power transmission. The mounting base 3 is used to bear the load of the entire device. The seated bearing 4 is used to support the drive shaft 1 and reduce rotational friction. The guide shaft 5 is used to bear radial load and reduce the friction of left and right reciprocating motion. The upper and lower guide wheel groups 6 are used to limit and receive the cable 11. The flange linear bearing 7 is used to reduce the friction of left and right reciprocating motion. The guide block 8 is mainly used to fix and limit the guide pin and also to receive the upper and lower guide wheel groups 6. The winding disc 9 is used to receive the cable of the multi-station device. The geared motor 10 provides power to the entire multi-station cycloidal device.

[0039] The drive shaft 1 has a reciprocating spiral groove with adjustable lead on its surface. A guide pin is provided in the reciprocating spiral groove and is embedded in the reciprocating spiral groove and connected to the guide block 8, thereby driving the guide block 8 and the upper and lower guide wheel group 6 to reciprocate left and right. The geared motor 10 drives the drive shaft 1 to rotate, and the guide pin moves back and forth along the spiral groove, driving the guide block 8 and the upper and lower guide wheel group 6 to move left and right synchronously.

[0040] Since the rotation of the drive shaft 1 is transmitted from the winding roller 14, the cable speed V during winding can be calculated. Assuming the length of one row of cable wound on the winding roller 14 is l, the time t for winding one row of cable, and the time t for the single stroke of the left-right reciprocating motion of the upper and lower guide rollers, the speed of the left-right reciprocating motion of the upper and lower guide rollers is V×1=(L×1) / t (L×1 is the single stroke of the left-right reciprocating motion of the upper and lower guide rollers, a known condition during design). By adjusting the lead P of the drive shaft 1 (P=V1 / V2, where V1 is the speed of the upper and lower guide rollers 6, and V2 is the rotational speed of the drive shaft 1), the cable 11 is ensured to be evenly arranged on the winding reel 9. In addition, multi-station design can be achieved by increasing the number of spiral groove groups or expanding the winding reel 9.

[0041] Example 1: Basic Three-Station Configuration

[0042] The drive shaft 1 has three sets of spiral grooves with the same lead machined on its surface, corresponding to three guide blocks 8. The geared motor 10 drives the drive shaft to rotate through the sprocket 2, and the guide pin drives the three sets of upper and lower guide wheels 6 to move synchronously left and right, so as to achieve the uniform arrangement of the three rolls of cable.

[0043] Example 2: Scalable Multi-Workstation Configuration

[0044] Four sets of spiral grooves are added to the drive shaft 1, expanding the winding disc 9 to a four-station configuration. By replacing the drive shaft with different leads, the compatible cable diameter range can be from 2mm to 50mm.

[0045] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
