Description

Technical Field

[0001] The utility model relates to the field of industrial sewing machines, in particular to a synchronously moving sewing machine template structure. Background Art

[0002] In an industrial sewing machine, a hook is located at the top and a bobbin is located at the bottom. A movable template is located between the hook and bobbin, where the pre-sewn fabric is positioned. The template moves the fabric along the X and Y axes, thus achieving the sewing of the fabric.

[0003] However, due to the large span of the existing X-axis, a dual-servo motor structure is generally used to achieve synchronous movement of the X-axis. However, this design has high requirements for template debugging and is prone to synchronization problems. When this problem occurs, it is generally necessary to reset and then return the servo motor to "zero" (the corresponding servo motor cost is also high) to achieve synchronization of the X-axis. However, this debugging requires more professional technicians to set up, so it is more troublesome. Utility Model Content

[0004] The main purpose of the utility model is to propose a synchronously moving sewing machine template structure, aiming to improve the existing template drive structure, realize the movement of its X-axis and Y-axis, and make the synchronization more stable when the X-axis moves.

[0005] To achieve the above-mentioned purpose, the present invention proposes a synchronously moving sewing machine template structure, comprising:

[0006] A base, wherein the lower wall of the base is provided with two longitudinal guide seats arranged at intervals, the longitudinal guide seats are slidably mounted with a longitudinal slide, the outer periphery of the longitudinal guide seats is provided with a closed-loop longitudinal belt, the upper wall of the longitudinal belt is connected to the longitudinal slide, and the two ends of the longitudinal belt are respectively provided with a first driving roller and a second driving roller;

[0007] a first drive device, comprising a first rotary motor and a drive shaft connected to the first rotary motor, wherein both ends of the drive shaft respectively cooperate directly or indirectly with two second drive rollers and can drive the two second drive rollers to rotate simultaneously; (and thereby drive the longitudinal belt to reciprocate and the longitudinal slide to move along the length direction of the longitudinal guide seat);

[0008] A transverse frame, both ends of which are respectively fixed to the longitudinal slide (i.e., the Y-axis direction), the transverse frame is provided with a transverse guide rail and a transverse slider slidably mounted on the transverse guide rail, the transverse slider is installed with a template frame, and the transverse frame is provided with a second driving device for driving the transverse slider to move.

[0009] In the actual design, a single first rotating motor is used to rotate the drive shaft, thereby driving the longitudinal belt to move back and forth, and driving the longitudinal slide to move along the length direction of the longitudinal guide seat (i.e., the X-axis direction). Therefore, its synchronization can be stably solved. Assuming that the longitudinal sliders on both sides are offset, the two longitudinal slides are reset, and then the drive shaft is idle for a predetermined number of circles to achieve reset. The structure is simple, the synchronization is better, and one servo motor is reduced, the production cost is lower, and the market competitiveness is effectively improved.
