Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a switching lamination device. Background Art

[0002] Current film feed mechanisms, such as those in the Chinese utility model patent application CN217351769U, titled "A Multi-Layered Film Pushing Device for a Computerized Embroidery Machine," can only embroider two types of sequins. To create a pattern with four sequins, a film feed mechanism must be installed on each side of the needle bar. After the sequins on one side are finished, the machine must be stopped and the needle position on the other side must be switched to embroider the other two sequins. However, the embroidery needle can make hundreds of round trips per minute when embroidering sequins, and starting and stopping the needle takes a significant amount of time, resulting in extremely low efficiency.

[0005] A switching lamination device includes a needle bar frame, which is connected to a mounting base through a lifting mechanism. Two first guide rails are provided on the mounting base. The first guide rails are slidably connected to a slide for mounting a film feeding mechanism. The mounting base is provided with a linear reciprocating drive mechanism. The linear reciprocating drive mechanism drives the slide to slide on the first guide rail so that the two film feeding mechanisms can be alternately in the working position.

DETAILED DESCRIPTION

[0026] The present invention is further illustrated below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications of various equivalent forms of the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0027] like Figure 1-9As shown, a switchable lamination device includes a needle bar frame 1, which is connected to a mounting base 3 through a lifting mechanism 2. The lifting mechanism is a cylinder. The telescopic rod of the cylinder is fixedly connected to the needle bar frame obliquely downward, and the cylinder barrel of the cylinder is fixedly connected to the mounting base. The needle bar frame is installed with a second guide rail 11, and the second guide rail is slidably matched with a slider 31 fixed to the mounting base. The needle bar frame is installed with a concave positioning block 12, and the mounting base is installed with a convex positioning block 32. The concave and convex positioning blocks match to ensure that the mounting base is pushed into place. Two first guide rails 33 are installed on the mounting base, and the angle between the two first guide rails is 50 degrees. The first guide rail is slidably connected to the slide 4, and the slide is connected to the film feeding mechanism 6 through the fine-tuning mechanism 5. The film feeding mechanism is a prior art and will not be described in detail. The fine-tuning mechanism includes an upper base 51 fixed to the slide, an upper adjusting rod 52 pivotally connected to the upper base, and an upper adjusting rod threadedly connected to the adjusting block 53. The upper part of the adjusting block is slidably connected to the upper base, and the lower part of the adjusting block is slidably connected to the lower base 54. The lower base is fixed to the film feeding mechanism, and the lower base is pivotally connected to the lower adjusting rod 55. The lower adjusting rod is threadedly connected to the adjusting block. The upper and lower adjusting rods are perpendicular to each other, and the adjusting block includes an inverted upper dovetail portion. 531, the bottom surface of the upper dovetail is integrally formed with the lower dovetail 532, the axis of the upper adjusting rod is parallel to the axis of the upper dovetail, the axis of the lower adjusting rod is parallel to the axis of the lower dovetail, the upper base is provided with an upper dovetail groove 511 that is slidably matched with the upper dovetail, and the lower base is provided with a lower dovetail groove 541 that is slidably matched with the lower dovetail. The fine-tuning mechanism can more accurately adjust the position of the feeding mechanism relative to the embroidery needle, thereby ensuring the quality of the embroidery piece. The mounting seat is provided with a linear reciprocating drive mechanism 7, which includes a motor 71 fixedly connected to the mounting seat, and the output shaft of the motor The driving wheel 72 is fixed, and the driving wheel is connected to the driven wheel 74 through a belt 73. The driven wheel is fixed to the rotating shaft 75 that is rotatably connected to the mounting seat. Due to space limitations, the installation position of the motor is far away from the first guide rail, so the rotating shaft needs to be driven by a belt drive. The rotating shaft is fixed to the turntable 76, and a slide groove is provided on the bottom surface of the turntable. The top surface of the slide is installed with a rolling pin 41 inserted into the slide groove. The slide groove includes a semi-annular groove 761 concentric with the rotating shaft, and arc grooves 762 are provided at both ends of the semi-annular groove that turn toward the rotating shaft. The turntable is located at the junction of the semi-annular groove and the arc groove to form a flange 763.

[0028] The specific working process and principle of the present invention are as follows: initially, the film feeding mechanism on the left is in the working position and the film feeding mechanism on the right is in the non-working position. When the film feeding mechanism on the left is completed, the motor output shaft drives the rotating shaft to rotate forward through the belt, and the rotating shaft drives the turntable to rotate forward. The left rolling pin is pushed by the flange to drive the left slide to move along the first guide rail away from the embroidery needle 8. That is, the film feeding mechanism on the left starts to withdraw from the working position. At this time, the film feeding mechanism on the right is still in its original position (non-working position) until the arc groove on the right rotates close to the rolling pin on the right. The right rolling pin drives the right slide to move along the first guide rail close to the embroidery needle under the squeezing and pushing of the side wall of the right arc groove, and the film feeding mechanism on the right starts to move toward the embroidery needle until the rolling pin on the right completely enters the arc groove and the rolling pin on the left completely enters the semi-annular groove. The film feeding mechanism on the left is sent to the non-working position and the film feeding mechanism on the right is sent to the working position. After the film feeding mechanism on the right completes its work, it operates in the reverse direction to alternately output different gold films to the embroidery needle. The utility model saves a lot of time spent on starting and stopping the embroidery needle, thereby greatly improving production efficiency. There is a certain time difference when the two feeding mechanisms switch, which can effectively avoid interference and has high safety.
