Description

Technical Field

[0001] The utility model relates to a bead threading mechanism. Background Art

[0002] The bead threading mechanism is used for continuously threading beads onto the bead threading rod and supplying beads to the bead feeding device.

[0003] The existing beading mechanism includes a barrel for accommodating beads and driving the beads to rotate. The barrel is provided with a motor for driving the barrel to rotate. The barrel is provided with a beading rod placed in the barrel. The beading rod body is usually arranged vertically up and down. The upper end of the beading rod is bent, and the end is bent and placed in the barrel so that the end is arranged relative to the beads rotating with the barrel. The beads rotating with the barrel move relatively at high speed relative to the end, and the beads are threaded on the end of the beading rod through the probability of collision. And with the continuous threading of beads and the impact force of the movement of beads in the barrel, the beads at the end of the beading rod are gradually pushed onto the beading rod. The driving force is the power for threading the beads on the beading rod, but the driving force will cause the curved part of the upper end of the beading rod to gradually retreat, or / and cause the upper end of the beading rod to form reciprocating vibration. During the continuous working process, the retreat of the upper end of the beading rod or the reciprocating vibration will change the position of the beading rod, resulting in inaccurate positioning of the beading rod, affecting the threading and continuous bead feeding.

[0004] In order to solve the above problems, a positioning wheel is usually set at the curved part of the bead threading rod, and the bead threading rod is circled on the wheel, or the bead threading rod is clamped by the wheel. The wheel is large in size and will increase the resistance of the beads to sliding on the bead threading rod to a certain extent, resulting in poor bead threading and beads easily getting stuck on the wheel. When applied to a multi-bead feeding device, the larger volume will obviously increase the volume of the bead threading mechanism corresponding to the multi-bead feeding device, affecting the installation and arrangement of the multi-bead threading mechanism, resulting in the installation and arrangement of the entire multi-bead threading mechanism being relatively loose, and cannot be installed on an embroidery machine with a small head distance. It is obviously not in line with the trend of embroidery machine functional devices developing towards compact structures. Other structures of the existing stopper positioning bead threading rod also have the above-mentioned obvious defects, which greatly reduces the actual application value in the market. Utility Model Content

[0005] The utility model aims to solve the problems existing in the reuse of the existing bead threading mechanism and provides a bead threading mechanism with compact structure, small volume and good use effect, which is particularly suitable for the installation and arrangement of multiple bead threading mechanisms of a multi-bead feeding device.

[0006] The technical solution of the utility model to solve the existing problems is: a bead threading mechanism, including a barrel for accommodating beads, a driving motor for driving the barrel to rotate, and a bead threading rod, the upper end of the bead threading rod is provided with a bead threading end placed in the barrel, a bending portion is provided between the bead threading rod and the bead threading end, and as an improvement, it also includes a stop structure that can stop the bead threading rod, the stop structure includes a connecting block arranged on the barrel, and a stop arm extending from the connecting block to the rear part or / and the appropriate position of the upper rear part of the bending portion of the bead threading rod; the appropriate position is to enable the stop arm to effectively stop the bead threading rod from retreating during the bead threading process through appropriate debugging without affecting the position of the beads on the bead threading rod.

[0007] As a further improvement, the end of the stop arm that stops the bead threading rod has an extension handle extending toward both sides of the bead threading rod.

[0008] As a further improvement, the stop arm is provided with a bent handle portion bent toward the bead threading rod.

[0009] As a further improvement, a cover plate is provided on the barrel, and the connecting block is arranged on the cover plate.

[0010] As a further improvement, the barrel is also provided with a feeding bin, and the feeding bin is arranged on the cover plate.

[0011] Compared with the prior art, the utility model is provided with a stop structure that can stop the bead threading rod, and the stop structure includes a connecting block arranged on the cylinder body, and a stop arm extending from the connecting block to the rear part or / and the rear upper part of the bead threading rod. The connecting block is arranged on the cylinder body, and the stop arm extends from the connecting block to stop the rear part or / and the rear upper part of the bead threading rod, which can effectively stop the moving beads and the beads from pushing the bead threading rod backward during the bead threading process, and prevent the bead threading rod from tilting backward, jumping up, reciprocating large-amplitude vibration, etc., so that the bead threading rod can remain relatively stable. Its beneficial effects are that the utility model has a simple structure, a small volume, and does not require any power structure; it can minimize the impact on the bead threading mechanism, which is beneficial to reducing the volume of the bead threading mechanism, making the structure more compact, and convenient for installation on an embroidery machine with a smaller head distance. The structure of the utility model can be applied to a single-bead feeding device, and is particularly suitable for the bead threading of a multi-bead feeding device.
