Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a plucking mechanism for gold sheet embroidery. Background Art

[0002] Gold sequin embroidery machines are usually equipped with a feeding device, which is used to deliver the gold sequins to the working needle position, and the sequins are embroidered on the fabric by the needle bar. The feeding device is usually equipped with a paddle mechanism for conveying gold sequins. In existing paddle mechanisms, the paddle fork usually uses the tension of a spring to paddle. For many gold sequins (large sequins), such as 12-22mm large sequins, the paddle fork needs to move a long distance. The spring tension alone cannot deliver the sequins in time, and it is easy to leak sequins. Summary of the invention

[0003] In order to solve the above problems of the prior art, the utility model provides a plucking mechanism for gold sheet embroidery, which adopts a motor and a spring to drive a plucking fork, is suitable for sending gold sheets with larger diameters, and is not prone to leakage.

[0006] Furthermore, the film feeding bottom plate is provided with a film feeding groove corresponding to the film feeding mechanism.

[0007] Furthermore, the cam is arranged on the film feeding drive mechanism, and the slot is arranged on the film feeding mechanism.

[0008] The slot is rotatably arranged on a rotating shaft, the rotating shaft is arranged on an end seat, and the slot is connected to the rotating shaft via a bearing.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with specific embodiments.

[0022] refer to Figure 1 , 2 3. A film feeding device for gold plate embroidery, comprising a film feeding base plate 1, at least one film feeding mechanism 4 and a corresponding end seat 3 arranged on the film feeding base plate, and also comprising a film feeding drive mechanism 5 for driving the shift fork provided on the film feeding mechanism 4 to retreat away from the machine needle, or to feed the film toward the machine needle 7, a driving structure 6 is arranged between the film feeding mechanism 4 and the film feeding drive mechanism 5, and the driving structure 6 comprises a matching cam 601 and a slot 602.

[0023] The utility model can be used for a single-sequin sheet feeding device, and can also be used for a multi-sequin sheet feeding device.

[0024] Preferably, the cam 601 is arranged on the film feeding drive mechanism 5, and the slot 602 is arranged on the film feeding mechanism 4. The slot 602 is rotatably arranged on the rotating shaft 11, the rotating shaft 11 is arranged on the end seat 3, and the slot 602 is connected to the rotating shaft 11 through a bearing.

[0025] The film feeding bottom plate 1 is provided with a film feeding slot 10 corresponding to the film feeding mechanism 4. The gold sheet is arranged in the film feeding slot 10, and the gold sheet is sent to the working position by the film feeding mechanism 4, and then the gold sheet is embroidered by the machine needle.

[0026] The film feeding mechanism 4 includes a shift fork 401 that slides in the film feeding slot 10 and is used to shift the film, and also includes a transmission rod 402 that is connected to the shift fork 401 at one end and connected to the slot 602 at the other end and is disposed on the shaft bearing. The film feeding drive mechanism 5 includes a drive motor 501, a drive arm 502 disposed on the drive shaft, a first transmission arm 503 and a second transmission arm 504.

[0027] One end of the driving arm 502 is arranged on the driving shaft, and the other end is connected to the first transmission arm 503. One end of the first transmission arm 503 is connected to the driving arm 502, and the other end is connected to the second transmission arm 504. One end of the second transmission arm 502 is connected to the first transmission arm 503, and the other end is connected to the cam 601.

[0028] refer to Figure 2 ,by Figure 2 When the driving motor drives the driving arm 502 to rotate clockwise, the first transmission arm 503 moves upward, and the second transmission arm 504 moves upward accordingly. Since the cam 601 and the slot 602 cooperate with each other, the cam 601 can drive the slot 602 to lift upward, that is, rotate clockwise around the rotating shaft. Since the slot 602 is connected to the transmission rod 402, and the other end of the transmission rod 402 is connected to the fork 401, the rotation of the slot 602 will drive the transmission rod 402 to rotate clockwise, thereby driving the fork 401 to retreat away from the needle.

[0029] When the driving motor drives the driving arm 502 to rotate counterclockwise, the first transmission arm 503 moves downward, and the second transmission arm 504 moves downward accordingly. Since the cam 601 and the slot 602 cooperate with each other, the cam 601 can drive the slot 602 to press downward, that is, rotate counterclockwise around the rotating shaft. Since the slot 602 is connected to the transmission rod 402, and the other end of the transmission rod 402 is connected to the shift fork 401, the rotation of the slot 602 will drive the transmission rod 402 to rotate counterclockwise, thereby driving the shift fork 401 to send the film toward the needle direction.

[0030] A reset spring 9 is provided between the transmission rod 402 and the bracket 8 provided on the end seat 3 to drive the film feeding mechanism 4 to feed the film in the direction of the needle 7. The reset spring 9 is provided between the bracket 8 and the transmission rod 402. If the transmission rod and the shift fork move backward, the reset spring 9 is stretched and deformed. Under the action of the spring elastic force, the transmission rod and the shift fork are driven to move and reset in the direction of the needle, that is, to feed the film forward.

[0031] In the prior art, the film feeding drive mechanism 5 usually only drives the fork provided by the film feeding mechanism 4 to retreat away from the direction of the needle, and uses a spring to reset the fork, thereby shifting the film forward. However, for large films, the fork needs to move a long distance, and relying solely on the spring tension may cause film leakage or untimely delivery.

[0032] The utility model mainly utilizes a driving motor to drive a shift fork to deliver films, and utilizes a reset spring to assist in driving the shift fork forward, so that the film delivery speed is faster and the efficiency is higher. For some large films, the driving force is greater, and problems such as film leakage and delayed film delivery are less likely to occur.

[0033] A plurality of sheet feeding mechanisms 4 may be arranged side by side on the end seat 3 , and a driver for driving the corresponding sheet feeding mechanisms 4 to cooperate with the sheet feeding driving mechanism 5 may be arranged on the upper end of the end seat.

[0034] A limit rod 2 is provided at the lower end of the slot 602 to limit the angle at which the slot 602 rotates downward.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
