Description

Embroidery machine embroidery frame structure, embroidery machine

Technical Field

The utility model belongs to the technical field of the embroidery machine, especially, relate to an embroidery machine embroidery frame structure, embroidery machine.

Background

The computerized embroidery machine includes embroidery part and frame shifting part, and the main shaft motor in the embroidery part has speed changed via speed varying mechanism, one output to the upper shaft to drive the needle rod to move up and down and the other output to the lower shaft to drive the rotating shuttle to rotate and supply bobbin thread. An X-axis driving motor and a Y-axis driving motor of the frame moving part are respectively connected with the embroidery frame through a driving mechanism so as to drive the embroidery frame to reciprocate along the X-axis direction and the Y-axis direction in the working surface. The controller receives the pattern data and outputs a spindle motor control signal, an X-axis drive motor control signal and a Y-axis drive motor control signal according to a preset strategy so as to drive the spindle motor, the X-axis drive motor and the Y-axis drive motor. When the computerized embroidery machine works, the needle rod drives the needle thread to move up and down, and the rotating shuttle is matched with the needle rod to rotate, so that the embroidery action is completed; the embroidery frame reciprocates in the X-axis and Y-axis directions of the working plane, and the embroidery pattern is obtained by moving the embroidery frame along the X-axis and Y-axis directions.

With the development of embroidery patterns towards large size, common embroidery frames cannot meet the embroidery requirements, and embroidery frames with different sizes need to be replaced according to the sizes of the embroidery products to complete embroidery, but the method is inflexible and is not suitable for the embroidery process of embroidery products with any sizes, and with the increase of the sizes of the embroidery frames, the rigidity of the embroidery frames is reduced, so that the embroidery frames deform and bend, and the embroidery quality is influenced. The large-size change of the embroidery pattern may be an extension change of a longitudinal length (i.e., a length of the embroidery material placed on the embroidery frame of the embroidery machine in the Y-axis direction), an extension change of a transverse length (i.e., a length of the embroidery material placed on the embroidery frame of the embroidery machine in the X-axis direction), or an extension change of the longitudinal length and the transverse length. In the case of the longitudinal length extension change, the length of the Y-axis guide rail, the length of the embroidery frame in the Y-axis direction, and the length of the embroidery machine table in the Y-axis direction in the Y-drive system can be extended on the conventional embroidery frame (refer to the embroidery frame structure disclosed in patent application CN 201911022584.1). For the situation of extension change of the transverse length, the existing embroidery frame cannot be directly utilized to complete the embroidery process. Because the length of the X-axis guide rail in the existing X-drive system is generally within 1.8 meters, the adjacent Y-drive mechanisms are spaced about 1.8 meters apart. The X guide rail (the X guide rail is arranged along the Y-axis direction of the embroidery machine bedplate) and the Y guide rail (the Y guide rail is arranged along the X-axis direction of the embroidery machine bedplate) are orthogonally arranged above the embroidery machine bedplate, the X guide rail is arranged below the Y guide rail, and the length of the X-axis guide rail is smaller than the distance between the two Y-axis guide rails arranged at the two sides of the X-axis guide rail, so that the embroidery frame cannot interfere in the movement of the X-axis direction. Once the size of the embroidery pattern is extended to the transverse length, the size is greater than 1.8 m, if the embroidery material is wall cloth, the transverse size of the embroidery pattern may reach 2.8 m, the X guide rail inevitably interferes with the Y guide rail when the embroidery frame moves in the X-axis direction, and finally the effective X-axis stroke of the X guide rail only can be the distance between two Y-axis guide rails arranged on both sides of the X-axis guide rail, which cannot complete the embroidery. If the existing embroidery machine is used for finishing the embroidery with the size, the embroidery needs to be finished in a segmented mode, the embroidery with the size of 2.8 meters is finished for 2 times, and the embroidery is finished according to the size of 1.4 meters every time, so that the problem of discontinuous patterns of the final embroidery is caused, and the quality of the embroidery is greatly reduced.

The invention patent application CN201810817157.1 discloses a large-stroke embroidery machine, and particularly discloses an embroidery machine which comprises an embroidery machine body, a girder, an embroidery frame, X, Y directional guide rail assemblies and corresponding drives, wherein the girder, the embroidery frame, the X, Y directional guide rail assemblies and the corresponding drives are arranged on the embroidery machine body, each X, Y guide rail assembly comprises a corresponding X, Y directional guide rail and a sliding block sliding on the corresponding guide rail, the embroidery machine further comprises at least one suspension guide rail which is arranged at the corresponding position of the embroidery frame X guide rail assembly and is relatively fixed above the embroidery frame, the suspension guide rail is parallel to the Y directional guide rail, each suspension guide rail of the suspension guide rail is provided with at least one second sliding block, the second sliding block can be slidably suspended on the corresponding suspension guide rail, and the second sliding block is fixedly connected with the corresponding position of the embroidery frame. The X guide rail component is the Y guide rail actually, and the Y guide rail component is the X guide rail actually. As for the improvement aspect of the stability of the tabouret, only one end of the suspension guide rail is connected to the cross beam, and the stability of the other end of the suspension guide rail mainly depends on the strength of the suspension guide rail and the matching between the sliding block and the suspension guide rail.
