Description

Technical Field

[0001] The utility model belongs to the technical fields of clothing, curtain, car seat cover processing, etc., and particularly relates to an adjusting device for a strip inserting part and a sewing machine including the device. Background Art

[0002] A strip is a material used for decoration, mounting or connection. In product manufacturing, strips are usually used to decorate clothes, bags, pillows, curtains, car seat cover splicing, etc. They can be made of fillers such as cotton ropes or simply folded and ironed cloth strips. Usually, during the sewing process, when sandwiching a woven tape strip, it is manually stacked with the fabric to be inserted and then placed under the sewing needle on the sewing machine table. The operator holds the woven tape strip by hand and steps on the pedal to pull and sew bit by bit; this method not only has low sewing work efficiency, but also the woven tape strip sewn is prone to bending and skewing, thus affecting the overall aesthetics of the sewn product. Therefore, some auxiliary tools have emerged. These tools usually have a guiding drawstring for threading the woven tape strip, so that when sewing, it is not necessary to hold the woven tape strip by hand and step on the pedal to pull and sew bit by bit, the work efficiency is improved, and the woven tape strip sewn on the sewn product is not prone to bending and skewing, thus better maintaining the overall aesthetics of the sewn product. However, these tools are often fixedly installed on the sewing machine table through screws, and other tools are needed to complete the disassembly and installation process, which is relatively inconvenient. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an adjusting device for a strip inserting part and a sewing machine. The specific technical solutions are as follows:

[0004] An adjusting device for a strip inserting part includes a guiding plate for installing the strip inserting part, a horizontal rotation assembly of the strip inserting part and an installation assembly. One end of the horizontal rotation assembly is fixedly connected to the installation assembly, and the other end is fixedly connected to the guiding plate. The installation assembly includes a base, a mounting plate, a locking block and a knob. The base is provided with a locking block installation groove, the locking block is arranged in the locking block installation groove, the mounting plate is provided with a knob installation hole, the knob is arranged in the knob installation hole, a positioning column is arranged at the lower part of the knob, the locking block is provided with a positioning groove that can be engaged with the positioning column, and a positioning hole through which the positioning column can penetrate is arranged on the positioning groove. By setting the knob, the mounting plate can be quickly completed during installation and disassembly without the help of other tools.

[0005] Furthermore, the knob further includes a fixing part and a rotating part. The fixing part is sleeved on the rotating part, the fixing part is fixed on the mounting plate through a fixing bolt, and the positioning column is arranged on the rotating part. The fixing of the fixing part and the mounting plate enhances its structural stability, and the rotation of the rotating part and the locking block realizes engagement and disengagement to improve the structural flexibility.

[0006] Furthermore, the rotating part and the fixed part are coaxial. The rotating part includes a grip and a rotating shaft. The grip is in contact with the top surface of the fixed part. The rotating shaft rotates synchronously with the grip. The positioning post is arranged at the lower end of the rotating shaft. A positioning column is also arranged in the middle section of the rotating shaft, and the positioning column is in contact with the bottom surface of the fixed part. The contact between the grip and the top surface of the fixed part, and the contact between the positioning column and the bottom surface limit the relative displacement of the rotating part and the fixed part in the vertical direction, improving its stability.

[0007] Furthermore, the fixed part includes an upper fixed part and a lower fixed part. The lower fixed part extends downward from inside the upper fixed part and penetrates through the mounting plate. A limiting groove is arranged on the bottom surface of the lower fixed part, and the positioning column can slide in the limiting groove. When the positioning column slides to both ends of the limiting groove, the positioning column and the positioning hole are respectively in a coincident and staggered state, and the mounting plate and the bottom plate are respectively in a clamped and separated state, which greatly improves the convenience of quick disassembly.

[0008] Furthermore, the limiting groove is a right-angled sector-shaped groove, the positioning groove is a circular groove or a right-angled sector-shaped groove having the same shape as the limiting groove, and the positioning column and the positioning column extend perpendicularly from the axis of the rotating shaft to one side. After the positioning column passes through the positioning hole and rotates 90 degrees, it is completely misaligned, and it is in the most stable state as a whole.

The positioning column and the positioning column extend symmetrically and perpendicularly from both sides of the axis of the rotating shaft, and the clamping effect is better. The positioning column and the positioning column are parallel to each other, and the structure is more compact.

[0010] Furthermore, two long strip holes are linearly and juxtaposedly penetrated through the end of the base away from the strip inlet. The long strip holes are parallel to the long side direction of the base. Arranging two long strip holes can install two mounting bolts at the same time, which can prevent the mounting seat from rotating and make it always perpendicular to the sewing direction of the sewing needle on the sewing machine table. At the same time, compared with ordinary round holes, the long strip holes can reasonably adjust the front and rear positions of the base according to needs, facilitating the adjustment of the distance between the guiding opening and the sewing machine.

[0011] Furthermore, the guiding plate is provided with an inlet mounting hole for mounting the strip inlet. The inlet mounting hole is two parallel long round holes, and the guiding plate can mount the strip inlet on the inlet mounting hole through mounting screws. The screw connection makes its structure more compact.

[0012] Further, the horizontal rotation mechanism includes a connecting member, a set screw, and a connecting base plate.
