Description

Technical Field

[0001] The utility model relates to the field of sewing machine components, in particular to a feeding mechanism of a sewing machine. Background Art

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on a sewing material so that one or more layers of sewing material are interwoven or sewn together. Existing sewing machine feeding mechanisms mainly include two types: manual and automatic. The manual feeding mechanism is cumbersome to operate and inefficient. Although the automatic feeding mechanism improves efficiency, it still has problems such as complex structure, high failure rate, and poor adaptability to raw materials.

[0003] The Chinese utility model (Announcement No.: CN215757942U) discloses an automatic sewing machine with an automatic feeding function. The user places the fabric at the bottom of the transmission frame, and the second motor is started to drive the rotating rod to rotate, and the rotation of the rotating rod drives the active disk to rotate, and the rotation of the active disk drives the transmission belt to rotate, and the rotation of the transmission belt drives the driven disk to rotate, and the rotation of the driven disk drives the cross bar to rotate, and the rotation of the rotating rod and the cross bar drives the guide wheel to rotate, and the fabric is transmitted by the rotation of the guide wheel, so that it moves to the bottom of the sewing machine body for sewing operation. By using the limit spring, the transmission frame can be elastically limited as a whole, so that the guide wheel can be transmitted for fabrics of different thicknesses. Through the cooperation of the above structure, the device can achieve the function of automatic feeding, which solves the problem that the automatic sewing machines on the existing market do not have the function of automatic feeding, and the staff manually pushes the fabric, which is time-consuming and labor-intensive, and the speed is uneven, which is easy to cause the stitches to be too dense or too sparse, affecting the product quality. The problem is suitable for promotion and use.

[0004] It is found that there are at least the following problems in this technology: the above patent transmits the fabric by rotating the rotating rod, the active disk, the driven disk, the transmission belt, the cross bar and the guide wheel, but in actual use, since there is no limit on the other end of the fabric, the sewing needle at the bottom of the sewing machine body can easily cause the fabric to skew and move. Therefore, a feeding mechanism of a sewing machine is now proposed. Utility Model Content

[0005] In order to improve the problem that the sewing needle at the bottom of the sewing machine body easily causes the fabric to be skewed and moved because the other end of the fabric has no limit, the utility model provides a feeding mechanism of the sewing machine.

[0006] The utility model provides a feeding mechanism for a sewing machine, which adopts the following technical scheme:

[0007] A feeding mechanism of a sewing machine comprises a sewing platform, and a feeding assembly and a clamping assembly located above the sewing platform;

[0008] The feeding assembly includes a first motor, which is fixedly mounted on one side of the sewing platform, and two groups of first guide grooves are provided on the surface of the sewing platform. A first screw rod is fixedly connected to the output end of the first motor, and a first guide assembly seat is threadedly connected to the surface of the first screw rod. A second screw rod is also installed on the other side of the sewing platform, and the structure of the second screw rod is consistent with that of the first screw rod.

At the same time, it can improve the existing feeding mechanism. Since there is no limit at the other end of the fabric, the sewing needle at the bottom of the sewing machine body is prone to cause the fabric to skew and move.

[0011] Optionally, a fixing block is fixedly mounted on one side of the first guide assembly seat, and a second guide groove is formed on the surface of the first guide assembly seat.

[0012] By adopting the above technical solution, the second guide groove can play a guiding role.

[0013] Optionally, a sewing machine body is fixedly mounted on the top of the sewing platform, and a sewing needle is mounted on one side of the sewing machine body.

[0014] By adopting the above technical solution, the sewing needle can perform sewing operations on the fabric.

[0015] Optionally, an ironing compartment is fixedly mounted on one side surface of the sewing platform, and a third motor is fixedly mounted on one side of the ironing compartment.

[0016] By adopting the above technical solution, the third motor is started to drive the second limiting roller to rotate.

[0017] Optionally, the output end of the third motor is fixedly connected to a second limiting roller, and a steam outlet is provided on the surface of the second limiting roller.

[0018] By adopting the above technical solution, the second limiting roller can evenly spray high-temperature steam onto the fabric through the steam pipe and the steam port while conveying the fabric.

[0019] Optionally, a steam pipe is fixedly connected to one side of the second limiting roller.

[0020] By adopting the above technical solution, the setting improves the existing problem that the fabric is very likely to wrinkle after being placed for a long time and during transportation. If the wrinkles are not eliminated in time, the aesthetics of the fabric will be greatly affected after sewing.

[0021] Optionally, a first limiting roller is rotatably mounted on the bottom of the second limiting roller, and the first limiting roller is located inside the sewing platform.

[0022] By adopting the above technical solution, the first limiting roller cooperates with the second limiting roller to limit the conveyance of the fabric.

[0023] In summary, the utility model has the following beneficial effects:

[0024] 1. The utility model is provided with a clamping assembly. When in use, the two ends of the cloth can be passed through the ironing chamber and placed above the fixed block. Then the second motor is started to drive the third screw rod to rotate, thereby driving the clamping block to move downward to clamp and limit the two ends of the cloth. This arrangement improves the raw material adaptability of the feeding assembly and meets the feeding requirements of sewing raw materials of different materials and thicknesses;

[0025] 2. The utility model provides a feeding assembly, and starting the first motor can drive the first screw and the second screw to rotate, thereby driving the first guide assembly seat and the fabric to move horizontally along the first guide groove, and performing uniform and stable feeding. This setting can improve the efficiency of fabric sewing, avoid the problem of too dense or too sparse stitches affecting the quality of the fabric, and achieve the purpose of simplifying the structure, reducing the failure rate, and improving the stability, meeting the needs of efficient production. At the same time, it can improve the existing feeding mechanism. Because the other end of the fabric has no limit, the sewing needle at the bottom of the sewing machine body is easy to cause the fabric to be skewed and moved;

[0026] 3. The utility model sets up an ironing chamber, starts the third motor to drive the second limiting roller to rotate, and while conveying the fabric, can evenly spray high-temperature steam on the fabric through the steam pipe and the steam port to iron it. This arrangement improves the existing problem that the fabric is very likely to wrinkle after being placed for a long time and during transportation. If the wrinkles are not eliminated in time, the aesthetics of the fabric will be greatly affected after sewing. BRIEF DESCRIPTION OF THE DRAWINGS
