Description

Technical Field

[0001] This utility model relates to the field of bead embroidery technology, specifically to a bead embroidery driving mechanism. Background Technology

[0002] Bead embroidery, also known as beadwork, is a unique embroidery technique that is controlled by a drive mechanism.

[0003] For example, the Chinese authorized patent CN207699821U (Double Gold Sequin Embroidery Fork Drive Mechanism for Bead Embroidery) includes a cutting mechanism, a motor plate, upper and lower sheet feeding forks, and a drive motor mounted on the motor plate. A drive swing arm is mounted on the motor shaft of one motor, and drive connecting rods are mounted on the upper and lower sheet feeding forks respectively. As an improvement, the drive connecting rods are detachably mounted on the drive shaft, and a corresponding transmission swing arm is mounted on one drive shaft. This utility model detachably mounts the drive connecting rods on the drive shaft, and a corresponding transmission swing arm is mounted on one drive shaft. The drive swing arm and the transmission swing arm cooperate to drive the transmission swing arm to reciprocate, thus directly separating the traditional drive connecting rod into a drive connecting rod and a transmission swing arm. The positions of the drive swing arm and the transmission swing arm can be preset in advance to maintain corresponding cooperative positions. The fork adjustment process only requires adjusting the drive connecting rod, making it easy to adjust and use, especially suitable for bead embroidery machine heads.

[0004] However, the existing drive mechanism uses clamps and fasteners to fix the drive linkage. When connected to the drive shaft, the front surface is not easy to align with the front surface of the drive shaft, requiring multiple adjustments, which is time-consuming and laborious. Furthermore, after being fixed by compression, it is prone to overload during rotation, leading to rotational and installation position misalignment, resulting in poor stability. Therefore, it does not meet the current requirements. To address this, we propose a bead embroidery drive mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a bead embroidery driving mechanism to solve the problems mentioned in the background art. The driving linkage of the existing driving mechanism is fixed by clamping and fasteners. When connected to the driving shaft, the front surface is not easy to align with the front surface of the driving shaft, which requires multiple adjustments, which is time-consuming and laborious. Furthermore, after being fixed by squeezing, it is easy to overload during rotation, resulting in rotational deviation and installation position deviation, and poor stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bead embroidery driving mechanism, comprising: a motor plate, a first connecting seat at the rear end of the motor plate, a second connecting seat below the first connecting seat, a drive shaft at the front end of both the first and second connecting seats, a through hole on one side surface of the drive shaft, and a connecting rod assembly at the front end of the motor plate.

[0007] Preferably, the linkage assembly includes a drive linkage and a feed fork, with the feed fork located at one end of the drive linkage. The other end of the drive linkage has a mounting slot, and the drive linkage is fitted onto the outside of the drive shaft through the mounting slot.

[0008] Preferably, the upper surface of the mounting hole groove is provided with a tightening gap, and both sides of the inner wall of the tightening gap are provided with fastener holes, and the fastener holes penetrate the drive connecting rod. One end of the fastener hole is inserted into a threaded fastener, and one end of the threaded fastener passes through the fastener hole and is threadedly connected to a nut.

[0009] Preferably, the inner walls on both sides of the mounting slot are provided with positioning holes. A threaded rod is inserted into one end of the positioning hole, and the threaded rod passes through the positioning hole and the through hole in sequence, and is threadedly connected to a nut after passing through the drive connecting rod.

[0010] Preferably, the rear surface of the motor plate is provided with a mounting groove, a transmission swing arm is installed inside the mounting groove, a drive swing arm is provided on one side of the transmission swing arm, and a shaft groove is provided at one end of both the transmission swing arm and the drive swing arm, and a drive shaft is provided inside the shaft groove. A return spring is provided on the side surface of the transmission swing arm.

[0011] Preferably, a stepper motor is provided at one end of the drive shaft of both the second connecting seat and the drive swing arm, and a cutter drive mechanism is provided at the other end of the drive shaft of the drive swing arm.

[0012] Preferably, the front surface of the motor plate is provided with an inner groove, and the inner groove is open on both sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model provides a through hole on the surface of the drive shaft and positioning holes on both sides of the inner wall of the mounting slot. The positioning hole passes through the drive connecting rod, which is sleeved on the outside of the drive shaft through the mounting slot. The threaded rod passes through the positioning hole and the through hole in sequence, and is threaded with a nut after passing through the drive connecting rod. The nut is tightened to fix it. The threaded rod achieves the positioning connection between the drive connecting rod and the drive shaft, eliminating the need for multiple position adjustments, thus improving the convenience and accuracy of installation. Even when the threaded fasteners are loose, the threaded rod can still ensure the stability of the drive connecting rod and prevent it from falling off. The double-layer fixing method avoids falling off and causing safety accidents, thus improving safety. This solves the problem that the existing drive mechanism fixes the drive connecting rod by clamping and fasteners, which makes it difficult to align the front surface with the front surface of the drive shaft when connected to the drive shaft, requiring multiple adjustments, which is time-consuming and laborious. Furthermore, after fixing by compression, it is easy to overload during rotation, leading to rotational offset and installation position offset, resulting in poor stability.

[0015] (2) By setting a tightening gap on the upper surface of the mounting hole groove, the mounting hole groove can be expanded and reduced, which is suitable for drive shafts of different sizes. After one end of the threaded fastener passes through the fastener hole, a nut is threadedly connected. Through the shrinkage of the tightening gap, the end of the drive connecting rod with the mounting hole groove is tightened and fixed to prevent it from falling off, so that the drive connecting rod can be disassembled and replaced, improving flexibility.
