AI Technical Summary
In existing riveting machine wire feeding and straightening guide devices, the wire enters the riveting machine directly after passing through the wire threading roller, which may cause it to rewind and result in poor straightening effect.
The structure includes threading rollers, horizontal plates, vertical plates, and pressure rollers. After passing through the threading rollers, the wires are guided multiple times by the upper and lower pressure rollers and the two rows of first pressure rollers. Combined with the rubber sleeve to remove dust, the straightening effect is improved.
The multi-guided structure significantly improves the straightening effect of the wires, reduces rewinding, and ensures that the wires smoothly enter the riveting machine.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire laying and straightening guidance technology, and in particular relates to a wire laying and straightening guidance device for a riveting machine. Background Technology
[0002] In the production and processing of fasteners, such as when a riveting machine is producing threads, a wire straightening and guiding device is set on the front side of the riveting machine to straighten and guide the wires so that they enter the riveting machine in an orderly manner.
[0003] The wire feeding and straightening guide device for riveting machines consists of a wire-feeding roller that corrects the direction of the wire. The wire passes through the middle of the wire-feeding roller, thus straightening the wire. However, in actual implementation, the wire feeding and straightening guide device for riveting machines has been found to have areas for improvement: after passing through the wire-feeding roller, the wire may directly enter the riveting machine and may rewind, resulting in a need to improve the straightening effect. Utility Model Content
[0004] In view of the shortcomings and defects in the existing technology, the purpose of this utility model is to provide a wire feeding and straightening guide device for riveting machines, which solves the problem that in the existing wire feeding and straightening guide devices for riveting machines, the wires may roll back after passing through the wire feeding roller, resulting in the wire straightening effect needing to be improved.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a wire feeding and straightening guide device for a riveting machine, comprising a wire feeding roller, wherein the wire feeding roller has a wire feeding hole in the middle, and a fixing plate is fixed to the wire inlet of the riveting machine. A horizontal plate is connected to the right side of the fixing plate via a round rod, and a vertical plate is connected to the right side of the horizontal plate. A small vertical plate is fixed to the right side of the vertical plate, and the wire feeding roller is fixed to the right side of the small vertical plate. A through hole is provided on the small vertical plate at a position corresponding to the wire feeding roller. A rubber sleeve is fixed to the right side of the wire feeding roller. Two rows of first pressure rollers are rotatably connected to the horizontal plate. An upper pressure roller is rotatably connected to the vertical plate. Two lower pressure rollers are rotatably connected to both sides below the upper pressure roller on the vertical plate. One end of the wire passes sequentially through the wire feeding roller, the upper pressure roller and the lower pressure roller, and the two rows of first pressure rollers to enter the riveting machine.
[0006] As a further improvement of this utility model, the first pressure rollers in the front and rear rows are staggered left and right.
[0007] As a further improvement of this utility model, a notch is provided on the right side of the horizontal plate, and the vertical plate is inserted into the notch of the horizontal plate and detachably connected by bolts.
[0008] As a further improvement of this utility model, a first rod shaft is fixed on the horizontal plate at the position where the first pressure roller is set, the first pressure roller is rotatably connected to the first rod shaft, and a limit nut is threadedly connected to the first rod shaft above the first pressure roller.
[0009] As a further improvement of this utility model, a second rod shaft is fixed on the vertical plate at the position where the upper pressure roller and the lower pressure roller are set. The upper pressure roller and the lower pressure roller are rotatably connected to the second rod shaft, and a limit nut is threadedly connected to the second rod shaft above the upper pressure roller and the lower pressure roller.
[0010] Compared with the prior art, this utility model has the following advantages:
[0011] 1. By setting up a horizontal plate and a vertical plate, a first pressure roller is rotatably connected to the horizontal plate, and an upper pressure roller and a lower pressure roller are rotatably connected to the vertical plate. A small vertical plate is fixedly connected to the right side of the vertical plate, and a threading roller is fixed on the small vertical plate. After the wire is straightened by the threading roller, it passes between the upper and lower pressure rollers and between the two rows of first pressure rollers. After being straightened and guided again by the upper and lower pressure rollers and the two rows of first pressure rollers, it finally enters the riveting machine. This greatly improves the straightening effect of the wire and avoids or reduces the rewinding of the wire.
[0012] In addition, a rubber sleeve is fixed on the right side of the threading roller to remove dust and dirt adhering to the thread.
[0013] 2. By making a notch in the horizontal plate, the vertical plate is inserted into the notch and is detachably connected by bolts. Therefore, the vertical plate can be removed or rotated to adjust its angle. Attached Figure Description
