Description

Technical Field

[0001] This utility model relates to a multi-function shared drive device for a curved arm sewing machine, and more particularly to a mechanism that can control multiple different functions of a curved arm sewing machine with a single drive motor. Background Technology

[0002] Articulated boom sewing machines are mainly used for tasks such as double stitching. To make sewing work faster, many special functions are added, such as cutting mechanisms, thread loosening mechanisms, fabric pressing mechanisms, etc. The activation of the above mechanisms is usually driven by another power source. Therefore, when an additional special function mechanism is added, an additional power source is required, which may be a motor or a pneumatic source.

[0003] The conventional articulated arm sewing machine, as mentioned above, cannot integrate the power source for most special function mechanisms, resulting in a large number of power sources attached to the sewing machine casing. This not only affects the sewing work of the author, but also increases the installation cost and future maintenance cost, thus making improvement necessary.

[0004] The inventor of this invention has conducted further research and innovation, revealing the multi-tasking shared drive device for the curved arm sewing machine shown in this utility model. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-function shared drive device for a curved arm sewing machine, comprising: a drive motor fixed to the housing of a sewing machine, the drive motor shaft being connected to at least a first cam and a second cam for rotation; a first follower having its first end abutting against the wheel surface of the first cam, the first follower being capable of driving a first working mechanism; and a second follower having its first end abutting against the wheel surface of the second cam, the second end of the second follower being connected to a second working mechanism.

[0006] This utility model discloses a multi-tasking shared drive device for a curved arm sewing machine, wherein the drive motor is a stepper motor.

[0007] The multi-tasking drive device for the articulated arm sewing machine disclosed in this utility model refers to the first working mechanism as a slitting cutter.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0039] The following is a reference to the appendix. Figure 1 To be continued Figure 6This invention describes a multi-tasking shared drive device for a curved arm sewing machine, comprising: a drive motor 10 fixed to the machine housing S of the sewing machine, the drive motor 10 having a shaft 11 that drives at least a first cam 12 and a second cam 13 to rotate; a first follower 20 having its first end 21 abutting against the wheel surface of the first cam 12, and the first follower 20 being able to drive a first working mechanism 100 to move; and a second follower 30 having its first end 31 abutting against the wheel surface of the second cam 13, and the second end 32 of the second follower 30 driving a second working mechanism 200 to move.

[0040] This utility model discloses a multi-tasking shared drive device for a curved arm sewing machine, wherein the drive motor 10 is a stepper motor. The drive motor 10 can rotate forward or backward according to program commands to drive the first cam 12 and the second cam 13 to rotate. The drive motor 10 can also change its speed according to program commands to drive the first cam 12 and the second cam 13 to rotate at a set angular velocity.

[0041] like Figures 1-3 As shown, the multi-tasking drive device for the cantilever sewing machine disclosed in this utility model includes a first working mechanism 100, which is a cutting mechanism. The first driven member 20 can be a rod, with its first end 21 abutting against the wheel surface of the first cam 12, and its second end connected to a cutting blade 101, thus forming the first working mechanism 100, i.e., a cutting mechanism with a cutting function. The first driven member 20 is driven downwards by the rotation of the first cam 12, causing the connected cutting blade to move towards a bevel platform 102 to cut the sewing thread. The aforementioned cutting mechanism is a conventional mechanism used in cantilever sewing machines and is not the subject of this utility model application, therefore it will not be described in detail.

[0042] like Figure 1 , 4 As shown in Figures 5 and 6, the multi-tasking drive device for the articulated arm sewing machine disclosed in this utility model includes a second driven member 30 pivotally mounted in the machine housing S of the sewing machine. Its first end 31 contains a linkage arm for abutting against the wheel surface of the second cam 13, and the second end 32 of the second driven member 30 forms a lever for actuating the second working mechanism 200 to drive the second working mechanism 200 in motion.

[0043] The multi-tasking drive device for the articulated arm sewing machine disclosed in this utility model refers to a fabric pressing mechanism as the second working mechanism 200.

[0044] like Figure 5 , 6As shown, the multi-tasking drive device for the articulated arm sewing machine disclosed in this utility model further includes a third drive rod 33 for driving a third working mechanism 300.

[0045] The multi-tasking drive device for the curved arm sewing machine disclosed in this utility model refers to a thread-releasing mechanism 300, wherein the third working mechanism 300 is a thread-releasing mechanism.

[0046] The aforementioned pressing and loosening mechanisms are conventionally used in cantilever sewing machines and are not the subject of this utility model application, so they will not be described in detail.

[0047] The multi-function shared drive device for articulated arm sewing machines disclosed in this utility model controls the movement of two or more different working mechanisms by a single drive motor 10. This effectively integrates the power sources of multiple working mechanisms of the articulated arm sewing machine, thereby simplifying the transmission mechanism of the articulated arm sewing machine and reducing costs, thus demonstrating the novelty and progress of this utility model.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
