Description

Technical Field

[0001] This utility model relates to the field of sewing equipment technology, specifically to a bobbin device for a template machine. Background Technology

[0002] With the rapid development of industrial sewing technology, template sewing machines have been widely used in clothing, bags, and home furnishings due to their ability to efficiently and accurately sew complex patterns. In the working process of a template sewing machine, besides accurately feeding the fabric, a stable bobbin supply is crucial to ensuring sewing efficiency and quality. This requires the bobbin of the template machine to smoothly and accurately transmit the bobbin. Whether the bobbin structure can meet the requirements for stable bobbin transmission directly affects the automated operation of the template machine. Therefore, designing a stable and reliable bobbin top device is of paramount importance to the performance of the template machine.

[0003] In existing technologies, the top shuttle core device of a template machine typically employs mechanical linkage or pneumatic drive. In most top shuttle devices, the top shuttle rod is integrated with other components; therefore, replacing the top shuttle rod often requires disassembling numerous parts, making the adjustment process extremely complex. Furthermore, the design of the top shuttle device is not optimized. For example, direct cylinder drive of the top shuttle rod can lead to unstable power transmission, and the resulting impact forces are more likely to wear down the top shuttle rod, and may even damage the cylinder.

[0004] To overcome these problems, the industry has made some attempts at improvement. For example, the position of the top shuttle rod can be finely adjusted by adding shims or complex adjusting screws, but this introduces new parts, increasing the complexity of the structure and potential points of failure. In terms of transmission design, although pneumatic control is used, its linkage mechanism may have problems with low transmission efficiency, resulting in the cylinder output not being fully and effectively converted into the top shuttle action, wasting energy and having a slow response speed.

[0005] Therefore, the market urgently needs a new type of top bobbin device that can integrate drive, transmission, execution and limiting functions into one unit, and has the comprehensive advantages of compact structure, precise action, convenient adjustment and durability, so as to meet the requirements of modern high-efficiency template sewing production. Utility Model Content

[0006] To address the technical deficiencies in the background art, this utility model proposes a template machine top bobbin device, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows: A top shuttle core device for a template machine includes a top shuttle assembly, a limiting assembly, a connecting assembly, and a cylinder. The cylinder is fixedly connected to the connecting assembly, and the connecting assembly is fixedly connected to the top shuttle assembly. The top shuttle assembly includes a top shuttle shaft, a fixing block, a top shuttle rod, and a top shuttle cap. The lower end of the top shuttle shaft is fixedly connected to the connecting assembly, and the upper end is fixedly attached to the fixing block. The top shuttle rod is fixed to one side of the fixing block, and the top shuttle cap is fixed to the side of the top shuttle rod away from the fixing block. The lower end of the top shuttle shaft is fitted through the limiting assembly, and the top shuttle shaft rotates within the limiting assembly. The limiting assembly is located above the connecting assembly.

[0007] As a further technical solution of this utility model, the connecting assembly includes a fisheye connector, a top shuttle connecting rod, and a top shuttle connecting rod connector. The fisheye connector is fixedly connected to the cylinder, and the other end of the fisheye connector is rotatably connected to the top shuttle connecting rod. The other end of the top shuttle connecting rod is rotatably connected to the top shuttle connecting rod connector.

[0008] As a further technical solution of this utility model, the cylinder is characterized in that: the cylinder is arranged horizontally, a mounting base is fixed on the side of the cylinder away from the top shuttle assembly, and the cylinder and the fisheye connector are fixedly connected by a cylinder connecting rod.

[0009] As a further technical solution of this utility model, the limiting component includes a top shuttle shaft seat, a top shuttle shaft sleeve and a retaining ring, wherein the top shuttle shaft sleeve is fixed inside the top shuttle shaft seat and the upper end of the top shuttle shaft sleeve extends out of the top shuttle shaft seat.

[0010] The retaining ring is fixed to the upper end of the top shuttle shaft sleeve.

[0011] As a further technical solution of this utility model, the fixing block is bent horizontally in the direction away from the cylinder, and the top shuttle rod is bent in the opposite direction to the bending direction of the fixing block.

[0012] The beneficial effects of this utility model are as follows: By setting a top bobbin device next to the rotary hook assembly, the bobbin can be stopped in time when the thread is cut, preventing it from continuing to rotate due to inertia, thereby effectively avoiding the problem of not being able to thread due to the bobbin thread being too short, and improving the reliability of sewing operations; the overall structure is simple and compact, occupies little space, is easy to install and adjust, and runs stably, making it suitable for various automatic template sewing machines; the device has low requirements for the tightness of the fit between the bobbin and the bobbin case, and can still work effectively even if the bobbin is relatively loose in the bobbin case, thus broadening the applicability and stability of the equipment and reducing debugging and maintenance costs.

Detailed Implementation

[0015] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0016] This utility model discloses a top shuttle core device for a template machine, including a top shuttle assembly 1, a limiting assembly 2, a connecting assembly 3, and a cylinder 4. The cylinder 4 is fixedly connected to the connecting assembly 3 by threads, and the connecting assembly 3 is fixedly connected to the top shuttle assembly 1. The presence of the connecting assembly 3 enables the linear reciprocating motion output by the cylinder 4 to be accurately transmitted to the top shuttle assembly 1. The top shuttle assembly 1 includes a top shuttle shaft 11, a fixing block 12, a top shuttle rod 13, and a top shuttle cap 14. The lower end of the top shuttle shaft 11 is fixedly connected to the connecting assembly 3 by an interference fit. The upper end of the top shuttle shaft 11 is fixed with the fixing block 12. The top shuttle rod 13 is fixed to one side of the fixing block 12 by embedding. The side of the top shuttle rod 13 away from the fixing block 12 is fixed with the top shuttle cap 14. The lower end of the top shuttle shaft 11 passes through the limiting assembly 2, and the limiting assembly 2 is located above the connecting assembly 3. By limiting the position of the limiting component 2, the linear reciprocating motion transmitted from the connecting component 3 can be converted into the rotary reciprocating motion of the top shuttle shaft 11, and can drive the fixing block 12 and the top shuttle rod 13 fixed on the fixing block 12 to perform rotary reciprocating motion with the top shuttle shaft 11 as the circle.

[0017] The connecting assembly 3 includes a fisheye connector 31, a top shuttle connecting rod 32, and a top shuttle connecting rod connector 33. The fisheye connector 31 is fixedly connected to the cylinder 4 and can receive and transmit the linear reciprocating motion output by the cylinder 4. The other end of the fisheye connector 31 is rotatably connected to the top shuttle connecting rod 32, and the other end of the top shuttle connecting rod 32 is rotatably connected to the top shuttle connecting rod connector 33 via a pin. The other end of the top shuttle connecting rod connector 33 is fixedly connected to the top shuttle shaft 11. Through this segmented rotatable structure, coupled with the limitation of the limiting assembly 2, the linear reciprocating motion output by the cylinder 4 can be stably converted into rotary reciprocating motion, significantly reducing the friction between the components during the operation of the device. This not only saves space but also extends the service life of the device and minimizes the noise generated during operation.

[0018] The cylinder 4 is arranged horizontally, and a mounting base 41 is fixed on the side of the cylinder 4 away from the top shuttle assembly 1, so that the cylinder 4 can be stably installed inside the template machine head device (not shown in the figure). The output end of the cylinder 4 is provided with a cylinder 4 connecting rod 42, and the cylinder 4 connecting rod 42 is fixedly connected to the fisheye connector 31 by bolts.

[0019] The limiting component 2 includes a top shuttle shaft seat 22 and a top shuttle shaft sleeve 21. The top shuttle shaft seat 22 is fixed inside the template machine head device by bolts. The top shuttle shaft sleeve 21 is fixed inside the top shuttle shaft seat 22 by an interference fit, and the upper end of the top shuttle shaft sleeve 21 extends out of the top shuttle shaft seat 22. The lower end of the top shuttle shaft 11 passes through the top shuttle shaft sleeve 21, and the top shuttle shaft 11 and the top shuttle shaft sleeve 21 can rotate relative to each other. The presence of the limiting component 2 not only restricts the position of the top shuttle shaft 11 and, in conjunction with the connecting component 3, converts the linear reciprocating motion output by the cylinder 4 into rotary reciprocating motion, but also makes the overall structure of the device more stable and increases the overall rigidity of the mechanism. A retaining ring 5 is provided at the upper end of the top shuttle shaft sleeve 21. The retaining ring 5 is fixedly connected to the top shuttle shaft 11 by an interference fit, and the lower end of the retaining ring 5 is rotatably connected to the upper end of the top shuttle shaft sleeve 21. This structure can prevent dust or other particles from entering the interior of the top shuttle shaft sleeve 21, maintain the cleanliness of the interior of the top shuttle shaft sleeve 21, ensure that the reciprocating rotation of the top shuttle shaft 11 is not affected by the external environment, and extend the service life of the device.

[0020] To save space, the fixing block 12 is bent horizontally in the direction away from the cylinder 4, and the top shuttle rod 13 is bent in the opposite direction to the bending direction of the fixing block 12. This design not only makes it easier for the top shuttle cap 14 fixed at the end of the top shuttle rod 13 to contact the bobbin (not shown in the figure) inside the template machine head device, but also reduces the installation space required by the device and makes the structure more stable through folding.

[0021] To facilitate the disassembly of the fixing block 12, a vertical channel 121 is formed inside the fixing block 12 for engaging with the top shuttle shaft 11. A clamping opening 122 is provided on the side of the channel 121 away from the bend, and the clamping opening 122 communicates with the channel 121. The clamping opening 122 of the fixing block 12 is connected by a bolt. With the bolt loosened, the top shuttle shaft 11 can be easily inserted into and removed from the channel 121. Subsequently, by tightening the bolt, the angle of the clamping opening 122 is reduced, thereby compressing the top shuttle shaft 11 and generating a large frictional force, allowing the end of the top shuttle shaft 11 to be firmly embedded in the fixing block 12, thus achieving a detachable and fixed connection between the top shuttle shaft 11 and the fixing block 12.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
