TECHNICAL FIELD

[0001] The present application belongs to the technical field of embroidery machine frame, in particular to a kind of embroidery machine frame without fabric width. BACKGROUND

[0002] With the development trend of large-scale embroidery machine multi-head, the support column structure of the beam of embroidery machine frame has limited the width of the fabric entering the embroidery machine, that is, the distance between the two support columns is the maximum width of the fabric that can be embroidered, that is, the maximum transverse embroidery width.

[0003] The existing embroidery machine frame is installed and connected with support columns between the beam of embroidery machine and the base of embroidery machine. Without support column, the beam cannot be stably installed. The support column will inevitably interfere with the width of the fabric, that is, limit the width of the fabric. Of course, the transmission structure of the embroidery machine head and the rotating shuttle box of the traditional structure is directly transmitted up and down, which also limits the width of the fabric. Moreover, the main shaft of the embroidery machine head and the lower shaft in the rotating shuttle box lack synchronization performance, which affects the embroidery performance of the embroidery machine.

[0004] How to further expand the transverse embroidery width of the fabric and improve the synchronization of the main shaft of the embroidery machine head and the lower shaft in the rotating shuttle box is the object of research for those skilled in the art. SUMMARY

[0005] The present application provides an embroidery machine frame without fabric width, which has simple structure, no limit to the transverse embroidery width of the fabric, and synchronous operation of the main shaft of the embroidery machine head and the lower shaft in the rotating shuttle box under the condition of curve transmission, realizing the embroidery machine frame without fabric width.

[0006] An embroidery machine frame without fabric width, comprising an embroidery machine base, the embroidery machine base is connected with a beam support on the side, the beam support is connected with an embroidery machine beam, the beam support does not interfere with the width of the fabric, the embroidery machine beam is connected with an embroidery machine head, the embroidery machine base is connected with a rotating shuttle box, the embroidery machine head and the rotating shuttle box are connected through a transmission device, and the transmission device does not interfere with the width of the fabric. The beam support and the transmission device of the present application do not interfere with the width of the fabric, realizing the transverse embroidery width of the fabric without limit, and the transmission device realizes the synchronous driving performance of the embroidery machine head and the rotating shuttle box.

[0007] The beam support comprises a horizontal support and a vertical support, the horizontal support is connected with the embroidery machine beam, and the horizontal support, the vertical support and the embroidery machine base form a U-shaped structure after rotating 90 degrees clockwise, the opening of the U-shaped structure faces the fabric, and the beam support and the embroidery machine base do not limit the embroidery width of the fabric, further realizing the transverse embroidery width of the fabric without limit, and improving the overall structure firmness of the embroidery machine frame.

[0008] The embroidery machine base includes a first frame and a second frame distributed vertically, connected by connecting columns. The first frame is formed by two or more first longitudinal connecting rods and two or more first transverse connecting rods connected together. The second frame is formed by two or more second longitudinal connecting rods and two or more second transverse connecting rods connected together. The first and second longitudinal connecting rods connect to a vertical support. This type of embroidery machine base has a robust overall structure of first and second frames, and the vertical support connected by the first and second longitudinal connecting rods extends away from the fabric and into the side of the embroidery machine, thus not restricting the lateral embroidery width of the fabric.

[0009] Both the horizontal and vertical supports are square hollow steel pipe structures. The interior of the hollow steel pipe structure is used to install the transmission device, ensuring that the embroidery machine head connected to the main beam of the embroidery machine and the shuttle box connected to the base of the embroidery machine achieve synchronous driving performance between them.

[0010] The connection between the horizontal support and the embroidery machine beam is an L-shaped structure. This L-shaped structure connects a vertical connecting plate and a horizontal connecting plate, which fit snugly against the embroidery machine beam, improving the connection performance between the beam and the horizontal support. The embroidery machine beam is directly connected to the embroidery machine base without any uprights, avoiding interference with the lateral width of the fabric.

[0011] The main beam support is connected to a connecting seat on its side, and the connecting seat connects to another main beam support to form two interconnected main beam supports, or it can be connected to another main beam support to form two or more interconnected main beam supports, thereby forming a spliced ​​embroidery machine frame, achieving a long-distance, multi-head embroidery machine frame structure, and can even be extended indefinitely.

[0012] The horizontal support and the embroidery machine base are provided with a fabric movement space. The fabric movement space does not interfere with the first horizontal connecting rod in the horizontal direction, which increases the feeding direction of the fabric on the embroidery machine frame. It can be fed horizontally or vertically.

[0013] The transmission device includes a motor connected to a first pulley. The first pulley is connected to a second pulley via a first belt. The second pulley is connected to a main shaft installed inside the embroidery machine head. The main shaft is connected to a third pulley. The third pulley is connected to a fourth pulley via a second belt. The fourth pulley is connected to a fifth pulley via a first connecting shaft. The fifth pulley is connected to a sixth and seventh pulley via a third belt. The fifth, sixth, and seventh pulleys form a triangular structure. The seventh pulley is connected to an eighth pulley via a second connecting shaft. The eighth pulley is connected to a ninth pulley via a fourth belt. The ninth pulley is connected to a tenth pulley via a connecting shaft. The tenth pulley is connected to an eleventh pulley via a fifth belt. The eleventh pulley is connected to a lower shaft installed inside the shuttle box. The second, third, fourth, and fifth belts form a U-shaped structure after rotating 90 degrees clockwise. Because of its overall U-shaped structure, this transmission device achieves curved transmission performance while ensuring the shuttle box and the embroidery machine head are in a vertically corresponding relationship. It also achieves synchronous drive performance between the main shaft inside the embroidery machine head and the lower shaft inside the shuttle box.

[0014] A tensioning pulley device is installed between the fifth, sixth, and seventh pulleys. This tensioning pulley device includes a twelfth pulley located between the fifth and sixth pulleys. A first tensioning pulley, which is attached to the third belt, is installed on one side of the twelfth pulley, and a second tensioning pulley, also attached to the third belt, is installed on the other side. A third and fourth tensioning pulley are installed between the fifth and seventh pulleys. The third, fourth, fifth, and seventh pulleys are not located on the same straight line. This tensioning pulley device effectively extends the service life and transmission performance of the transmission device.

[0015] The fifth, sixth, and seventh pulleys are all installed inside the main beam support, while the eighth, ninth, and tenth pulleys are installed on the embroidery machine base. The transmission belt formed by the fifth, sixth, and seventh pulleys in conjunction with the third belt is parallel to the transmission belt formed by the eighth, ninth, and tenth pulleys in conjunction with the fourth belt to avoid mutual interference.

[0016] This invention achieves unlimited lateral embroidery width on the fabric by employing a beam support and transmission device that do not interfere with the fabric width, while also using a transmission device to achieve synchronous drive performance between the embroidery machine head and the shuttle box.
