Description

Technical Field

[0001] This utility model relates to the technical field of wire conveying devices, and in particular to a novel wire feeding mechanism. Background Technology

[0002] The patent number is ZL202223091035. X. The patent title is: "An Automatic Wire Feeding Device," a Chinese utility model patent, which specifically discloses the following technical solution: An automatic wire feeding device includes a cylinder, rollers, a fixed frame, a chain, a cabinet, a drive sprocket, a coupling, a cylindrical gear, a driven sprocket, and a reduction motor. The reduction motor is installed at the bottom inside the cabinet, and its output shaft is connected to the drive sprocket. A dual-shaft clutch is fixedly installed on the top of the cabinet. One end of the dual-shaft clutch is connected to the driven sprocket, and the other end is connected to the coupling. The drive sprocket and the driven sprocket are driven by a chain. A mounting bracket is fixedly installed on the top of the cabinet. A lower bearing plate is fixedly installed at the lower front of the mounting bracket. Two horizontally arranged rollers are installed on the lower bearing plate. A coupling is connected to the rollers on the lower bearing plate through a cylindrical gear. A cylinder mounting plate is installed at the upper front of the mounting bracket. A cylinder is fixedly installed on the cylinder mounting plate. The lower end of the cylinder piston is fixedly connected to a cylinder connecting plate. An upper bearing plate is installed on one side of the cylinder connecting plate. Two horizontally arranged rollers are installed on the upper bearing plate. The rollers on the upper bearing plate correspond vertically to the rollers on the lower bearing plate.

[0003] When the above-mentioned automatic wire feeding device performs the wire feeding action, the cylinder drives the cylinder connecting plate and the upper bearing plate to descend, so that the roller group composed of the rollers on the upper bearing plate and the rollers on the lower bearing plate presses the wire tightly. The geared motor drives the cylindrical gear to rotate through the chain transmission mechanism. The cylindrical gear drives the rollers on the lower bearing plate to rotate, thus moving the wire.

[0004] It should be noted that the aforementioned automatic wire feeding device still has the following shortcomings, specifically: Defect 1: It can only feed one wire, not multiple wires. Defect 2: The upper bearing plate is driven by a cylinder to achieve lifting and lowering, and the direction of cylinder movement is perpendicular to the direction of wire conveying. Also, the rollers on the lower bearing plate are deviated from the cylindrical gear. The above structural design increases the overall space occupied and the structure is not compact.

Detailed Implementation

[0021] The present invention will now be described in conjunction with specific embodiments.

[0022] Example 1, as Figure 1 and Figure 2 As shown, a novel wire feeding mechanism includes a fixed base 1, a drive motor 2 mounted on the fixed base 1, and a base top plate 11 arranged horizontally at the upper end of the fixed base 1. It should be noted that the drive motor 2 in this embodiment can be a servo motor.

[0023] Among them, such as Figures 1 to 4 As shown, the base top plate 11 is equipped with several wire feeding modules 3 arranged sequentially from left to right. A drive shaft 41 extending horizontally in the left-right direction is rotatably mounted on the rear end side of the base 1 on the base top plate 11. The drive motor 2 is driven and connected to the drive shaft 41. For each wire feeding module 3, a lower wire feeding roller 42 is fitted on the drive shaft 41 to prevent rotation. The lower wire feeding roller 42 can be connected to the drive shaft 41 to prevent rotation via an anti-rotation key. It should be noted that the power output shaft of the drive motor 2 is driven and connected to the drive shaft 41 via a synchronous belt drive mechanism, a gear drive mechanism, or a chain drive mechanism.

[0024] Furthermore, such as Figure 3 and Figure 4 As shown, the wire feeding module 3 includes a wire block 31, a movable swing arm 32, an upper wire feeding roller 33, and a drive cylinder 34 that moves back and forth. The wire block 31 is screwed and fastened to the upper surface of the base top plate 11, and the wire block 31 has a wire hole that completely penetrates along the front and back direction. The fixed end of the movable swing arm 32 is rotatably mounted on the rear end of the wire block 31, and the upper wire feeding roller 33 is rotatably mounted on the free end of the movable swing arm 32. The front end of the cylinder body of the drive cylinder 34 is hinged to the wire block 31, and the outer end of the piston rod of the drive cylinder 34 is hinged to the movable swing arm 32.

[0025] In the wire feeding module 3 of this embodiment, the wire passes through the wire hole of the wire block 31, which guides the wire to ensure it passes accurately between the upper wire feeding roller 33 and the lower wire feeding roller 42. The drive cylinder 34 drives the movable swing arm 32 to swing, pressing the wire between the upper wire feeding roller 33 and the lower wire feeding roller 42. The drive motor 2 drives the drive shaft 41 to rotate, and the lower wire feeding roller 42 rotates synchronously with the drive shaft 41. Under the power of the drive motor 2 and the drive cylinder 34, the wire is fed from front to back. When it is necessary to stop the wire feeding action, the drive cylinder 34 drives the movable swing arm 32 to swing, causing the upper wire feeding roller 33 to move away from the lower wire feeding roller 42.

[0026] It should be emphasized that the novel wire feeding mechanism of this embodiment has multiple wire feeding modules 3, that is, this embodiment can realize the feeding of multiple wires; in the process of realizing the feeding of multiple wires, each wire passes through the wire hole of one of the wire blocks 31, and the feeding start and stop of the corresponding wire can be controlled by controlling the action of the drive cylinder 34.

[0027] It should be further emphasized that in this embodiment, the drive cylinder 34 is horizontally mounted on the wire block 31, and the drive cylinder 34 moves back and forth, that is, the direction of movement of the drive cylinder 34 is consistent with the direction of wire feeding; also, in this embodiment, the lower wire feeding roller 42 is directly mounted on the drive shaft 41. Compared with the prior art, the novel wire feeding mechanism of this embodiment has a more compact structure.

[0028] In summary, the novel wire feeding mechanism of this embodiment has the advantages of novel structural design, good structural compactness, and the ability to transport multiple wires through the above structural design. Example 2, as Figure 3 and Figure 4 As shown, the difference between this embodiment 2 and embodiment 1 is that: the drive shaft 41 is equipped with a first drive gear 43 for each wire feeding module 3 to prevent rotation; wherein, the first drive gear 43 can be connected to the drive shaft 41 to prevent rotation via an anti-rotation key.

[0029] In addition, the rear end of the wire block 31 is pivotally connected to the second drive gear 35 and the third drive gear 36, and the free end of the drive swing arm is pivotally connected to the fourth drive gear 37, which is coaxially arranged and rotates synchronously with the upper wire feeding roller 33. The fourth drive gear 37, the third drive gear 36, the second drive gear 35 and the corresponding first drive gear 43 mesh in sequence. The fixed end of the drive swing arm is pivotally connected to the rear end of the wire block 31, and the pivot position of the fixed end of the drive swing arm is the same as the pivot position of the third drive gear 36.

[0030] During the wire feeding process of the wire feeding module 3 in this embodiment 2, the wire is squeezed between the upper wire feeding roller 33 and the lower wire feeding roller 42. The first drive gear 43 rotates synchronously with the drive shaft 41. Since the first drive gear 43, the second drive gear 35, the third drive gear 36 and the fourth drive gear 37 mesh in sequence, that is, the first drive gear 43 and the fourth drive gear 37 rotate synchronously in opposite directions, thereby causing the upper wire feeding roller 33 and the lower wire feeding roller 42 to rotate synchronously in opposite directions. Example 3, as Figure 4 As shown, the difference between this embodiment 3 and embodiment 1 is that: the upper surface of the wire block 31 is screwed with a fixed hinge seat 51 corresponding to each driving cylinder 34, and the front end of the cylinder body of each driving cylinder 34 is screwed with a movable hinge seat 52, and each fixed hinge seat 51 is hinged to the corresponding movable hinge seat 52. Example 4, as Figure 3 and Figure 4 As shown, the difference between this embodiment four and embodiment one is that each movable swing arm 32 is provided with an upwardly extending drive arm 321, and the piston rod extension end of each drive cylinder 34 is respectively equipped with a cylinder connector 341, and each cylinder connector 341 is respectively hinged to the corresponding drive arm 321. Example 5, such as Figure 1 and Figure 2 As shown, the difference between this fifth embodiment and the first embodiment is that a fixed crossbar 6 is installed at the upper end of the fixed base 1 on the rear end side of the wire feeding module 3, and a wire sleeve 7 is installed on each wire feeding module 3 corresponding to the fixed crossbar 6.

[0031] In this embodiment, the conductor sleeve 7 is used to guide the wire being transported from front to back to ensure that the wire is transported in the required direction.

[0032] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
