Description

Technical Field

[0001] This utility model belongs to the field of embroidery machine technology and relates to an active balancing mechanism for embroidery machines. Background Technology

[0002] The textile industry is a long-standing industry. From manual spinning to textile machines, and now to textile equipment used for centralized production, it represents the development history of the textile industry. The main structure of the existing embroidery machine used for textiles consists of an operating table, embroidery needles, shuttles, and other mechanisms. During operation, the embroidery needles drive the silk thread through the fabric. At this time, the shuttle hooks the silk thread on the embroidery needle and rotates it, and the silk thread on the shuttle is wrapped around it. Then the embroidery needle retracts, driving the silk thread out and completing one stitch. This type of embroidery machine is currently the most widely used type of embroidery machine, with advantages such as simple structure, convenient use, and low cost.

[0003] Because the rotation speed of an embroidery machine changes constantly during normal operation, and the number of machine heads working simultaneously also changes, the amplitude and frequency of the vibration force generated also change constantly. When an embroidery machine is installed on the second floor or higher, the long-term vibration of the embroidery machine can easily affect the building and cause safety hazards over time. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an active balancing mechanism for embroidery machines.

[0005] The objective of this utility model can be achieved through the following technical solution: an active balancing mechanism for an embroidery machine, comprising a mounting frame mounted on the embroidery machine frame, a vibration damping component mounted on the mounting frame, the vibration damping component comprising a sliding block that can slide up and down on the mounting frame and a vibration damping ring mounted on the sliding block, a rotating wheel mounted on the vibration damping ring, a rotating shaft passing through the rotating wheel, the rotating shaft being eccentrically mounted to the rotating wheel, the rotating shaft being rotatably connected to the mounting frame, and a driving component for driving the rotating shaft to rotate mounted on the mounting frame.

[0006] In the above-mentioned active balancing mechanism for an embroidery machine, a connecting shaft is provided at the lower end of the sliding block, and a connecting rod is provided at the top of the vibration damping ring, with the connecting rod connected to the connecting shaft.

[0007] In the above-mentioned active balancing mechanism for an embroidery machine, the driving component includes a mounting plate disposed on one side of the mounting frame, a drive motor disposed on the mounting plate, a drive wheel disposed on the output shaft of the drive motor, a driven wheel disposed on one side of the rotating shaft passing through the mounting frame, and a transmission belt disposed between the drive wheel and the driven wheel.

[0008] In the above-mentioned active balancing mechanism for an embroidery machine, two vibration damping rings are provided and are located at both ends of the connecting shaft.

[0009] In the above-mentioned active balancing mechanism for an embroidery machine, a limiting block is vertically arranged on the mounting frame, and a limiting groove matching the limiting block is provided on the sliding block.

[0010] Compared with the prior art, this utility model drives the rotating shaft to rotate through a driving component, thereby driving the rotating wheel on the rotating shaft to rotate. The rotating wheel is located inside the vibration damping ring, and the rotating shaft is eccentrically set and located below the rotating wheel. Therefore, the rotation can drive the rotating wheel to rotate during the rotation process, thereby causing the vibration damping ring to vibrate. The control unit on the embroidery machine controls the device to always maintain a vibration force opposite to that of the embroidery machine frame, thereby suppressing the vibration of the embroidery machine during operation. It can effectively solve the vibration generated during the operation of the embroidery machine, especially when the embroidery machine is placed in a multi-story factory building that is not on the first floor, it can reduce the vibration of the floor from the source.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example

[0015] As shown in Figure 1 and Figure 2 As shown, an active balancing mechanism for an embroidery machine includes a mounting frame 1 mounted on the embroidery machine frame. The mounting frame 1 has a mounting hole at its bottom. A vibration damping component is mounted on the mounting frame 1. The vibration damping component includes a sliding block 2 that can slide up and down on the mounting frame 1 and a vibration damping ring 3 mounted on the sliding block 2. A limiting block 7 is vertically mounted on the mounting frame 1. The sliding block 2 has a limiting groove 9 that matches the limiting block 7. The sliding block 2 can slide up and down along the limiting block 7.

[0016] The vibration damping ring 3 is provided with a rotating wheel 4, and a rotating shaft 5 passes through the rotating wheel 4. The rotating shaft 5 is eccentrically arranged with the rotating wheel 4. The rotating shaft 5 is rotatably connected to the mounting frame 1. A bearing is provided between the mounting frame 1 and the rotating shaft 5 to facilitate the rotation of the rotating shaft 5.

[0017] In this embodiment, the width of the rotating wheel 4 is approximately the same as the width of the vibration damping ring 3. Since the rotating shaft 5 and the rotating wheel 4 are eccentrically positioned, and the rotating shaft 5 is located below the rotating wheel 4, the rotating wheel 4 can perform elliptical motion around the rotating shaft 5 during rotation, thereby driving the vibration damping ring 3 to reciprocate, i.e., move up and down. A connecting shaft 8 is provided at the lower end of the sliding block 2, and a connecting rod 10 is provided at the top of the vibration damping ring 3. The connecting rod 10 is fixedly connected to the connecting shaft 8. In this embodiment, two vibration damping rings 3 are provided, located at opposite ends of the connecting shaft 8.

[0018] The mounting bracket 1 is also equipped with a driving component 6 for driving the rotating shaft 5 to rotate. The driving component 6 includes a mounting plate 61 disposed on one side of the mounting bracket 1, a driving motor 62 disposed on the mounting plate 61, a driving wheel 63 disposed on the output shaft of the driving motor 62, and a driven wheel 64 disposed on one side of the rotating shaft passing through the mounting bracket 1. A transmission belt 65 is disposed between the driving wheel 63 and the driven wheel 64. When the driving motor 62 rotates, it drives the driving wheel 63 to rotate. Since there is a transmission belt 65 between the driving wheel 63 and the driven wheel 64, it drives the driven wheel 64 to rotate. The driven wheel 64 is located at one end of the rotating shaft 5, and therefore can drive the rotating shaft 5 to rotate.

[0019] This invention uses a drive component 6 to drive a rotating shaft 5 to rotate, which in turn drives a rotating wheel 4 on the rotating shaft 5 to rotate. The rotating wheel 4 is located inside a vibration damping ring 3. The rotating shaft is eccentrically positioned below the rotating wheel 4. Therefore, during rotation, the rotating wheel 4 rotates, causing the vibration damping ring 3 to vibrate. The control unit on the embroidery machine controls the device to maintain a vibration force opposite to that of the embroidery machine frame, thereby suppressing the vibration of the embroidery machine during operation. This invention can effectively solve the vibration generated during the operation of the embroidery machine, especially when the embroidery machine is placed in a multi-story factory building that is not on the first floor, thus reducing the vibration to the floor from the source.

[0020] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
