Description

Technical Field

[0001] The utility model relates to the technical field of buttonhole machines, in particular to a round head buttonhole machine with a flattening function. Background Art

[0002] The eyelet buttonhole machine is an industrial sewing machine specially designed for sewing buttonholes on medium-heavy fabrics. It is a very important equipment in garment machinery and is mainly used to process buttonholes in various types of clothing. Buttonholes refer to holes or rings on clothing for passing buttons. They are usually located on the edge or specific position of clothing. When used with corresponding buttons, they can play a role of connection and fixation. The eyelet buttonhole machine can make the buttonhole beautiful in shape and the stitches even and strong, which can meet the requirements of different fabrics and designs.

[0003] However, in the prior art, the fabric may have certain wrinkles when it is produced. When processing the buttonholes of the fabric, the operator usually directly aligns the fabric with the needle position of the buttonhole machine to process the buttonhole. This method often has certain errors. During the process of sewing the buttonhole, the wrinkles of the fabric itself may be deformed by the tensile force, resulting in the size of the buttonhole not being consistent with the expectation, affecting its practicality and aesthetics, and even requiring re-sewing, which increases cost and time. Utility Model Content

[0004] The purpose of the present utility model is to solve the problem in the prior art that the cloth may have certain wrinkles when it is produced. When processing the buttonholes of the cloth, the operator usually directly aligns the cloth with the needle position of the buttonhole machine to process the buttonhole. This method often has certain errors. During the process of sewing the buttonhole, the wrinkles of the cloth itself may be deformed by the tensile force, resulting in the size of the buttonhole not being consistent with the expectation, affecting its practicality and aesthetics, and even requiring re-sewing, which increases cost and time. Therefore, a round head buttonhole machine with a flattening function is proposed.

[0005] The top end of the driving member is connected with the driving member to the upper end of the driving member to drive the transmission gear of the driving member to be connected with the driving member to the lower end of the driving member to be driven by the driving member to move the transmission gear of the driving member to the lower end.

[0006] Preferably, one end of the connecting plate is slidably engaged with the slider, and the other end of the lower pressing plate is slidably engaged with the bracket.

[0007] Preferably, a buttonhole machine head is fixedly connected to the upper end of the base.

[0008] Preferably, a processing device is fixedly installed below one end of the buttonhole machine head.

[0009] Preferably, a guide slot is provided in the middle of the upper end of the base, and a feed plate is slidably engaged in the middle of the guide slot.

[0010] Compared with the prior art, the advantages and positive effects of the present invention are:

[0011] 1. In the utility model, an infrared spotlight and a squeezing roller that can flatten the cloth in advance are provided. When in use, the two infrared spotlights can emit two infrared rays with right angles, which makes it convenient for the operator to align the edges and corners of the cloth more quickly, and then place the other side of the cloth on the bracket, and the motor drives the screw rod to rotate, thereby driving the lower pressing plate to press down, fixing the edges and corners of the cloth, and then driving the squeezing roller to move down through the telescopic rod to make it rest against the surface of the cloth, starting the motor second to drive the screw rod second to rotate, thereby driving the slider and the connecting plate and the squeezing roller below to slide along the slide groove to the side away from the bracket. During the process, the squeezing roller can exert a certain pressure on the cloth, flattening the surface of the cloth in advance, effectively eliminating wrinkles and folds, and then starting the buttonhole machine to fix the cloth, and then allowing the lower pressing plates and squeezing rollers on both sides to cancel the rest and limit on the cloth, facilitating processing, and effectively improving processing accuracy and reducing errors.

[0012] 2. In the present invention, the height of the squeezing rollers in contact with the fabric below the lower pressing plate and the connecting plate can be adjusted, so that the device can be applicable when processing fabrics of different thicknesses, and can flatten the fabric in advance to reduce wrinkles, effectively improving processing accuracy.

The motor 1 24 drives the screw rod 1 23 to rotate to press the lower pressure plate 25 downward to fix the corners of the other side of the cloth. Then, the telescopic rod 31 drives the squeezing roller 33 to move downward so that it rests on the surface of the cloth. The motor 2 28 is started to drive the screw rod 27 to rotate, and then the slider 29 and the connecting plate 32 and the squeezing roller 33 below are driven along the slide 26. Slide to the side away from the bracket 22. During the process, the squeezing roller 33 can apply a certain pressure to the cloth, making the surface of the cloth flat and effectively eliminating wrinkles and folds. Then start the buttonhole machine to fix the cloth, and then let the lower pressing plates 25 and squeezing rollers 33 on both sides cancel the abutment and limit of the cloth, which is convenient for processing. The height of the squeezing rollers 33 in contact with the cloth under the lower pressing plate 25 and the connecting plate 32 can be adjusted, so that the device can be applied when processing cloth of different thicknesses, and can flatten the cloth in advance to reduce wrinkles, effectively improving processing accuracy.
