Description

Technical Field

[0001] The utility model relates to the technical field of towel production, in particular to an auxiliary material pressing device for a four-side sewing system. Background Art

[0002] After a towel is cut and formed, it is necessary to use a sewing machine to edge the four sides of the towel. The sewing material pressing template of the four-side sewing system is driven by three servo systems to move, namely, the movement in the X-axis direction, the movement in the Y-axis direction, and the movement in the rotation axis direction (the center of the material pressing template rotates).

[0003] The sewing material pressing template is used to press the object to be sewn. The feeding for the sewing machine is completed by the combined movement of the X-axis, Y-axis, and rotation axis. Finally, the sewing machine sews the object to be sewn in a circle, that is, all four sides are sewn well. Since the template presses the object to be sewn to feed the sewing machine, and the template drives the object to be sewn to rotate one week so that the sewing machine sews the four sides well, the middle of the object to be sewn is pressed by the template, and about 15 millimeters are left around for the sewing machine to sew. The sewing machine has feed teeth. When the sewing machine sews the object to be sewn, the feed teeth will feed forward. The sewing material pressing template drives the object to be sewn to feed synchronously with the feed teeth of the sewing machine.

[0004] However, since the feed teeth and the sewing material pressing template cannot be completely synchronized, especially at the beginning of sewing, when the fabric just enters the sewing machine from the front, only a few feed teeth exert force, or when sewing to a corner, the error between the rotation of the sewing template and the linear feeding of the sewing machine is relatively large, which easily causes the object to be sewn to wrinkle and become uneven. Summary of the Invention

[0005] In view of the deficiencies of the above-mentioned prior art, an auxiliary material pressing device for a four-side sewing system is provided, which improves the finished product rate and high-quality product rate of the sewn product, and can sew a beautiful product without reducing the sewing speed when starting sewing and turning corners, thereby improving work efficiency.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is that an auxiliary material pressing device for a four-side sewing system includes a sewing machine body, and a guide rail provided on the sewing machine body. A base is provided on the guide rail and runs along the guide rail. A vertical plate is provided on one side surface of the base. A guiding mechanism is provided on the inner vertical surface of the vertical plate. A fixed seat is provided on the guiding mechanism. A driving motor is provided on the top of the fixed seat. A driving shaft is provided on the driving motor. A pressing plate is provided at the bottom of the driving shaft. A driving device for driving the fixed seat to run along the guiding mechanism is provided on the outer vertical surface of the vertical plate. A fixing plate is provided at the bottom of the fixed seat. A bearing plate is provided on the fixing plate. A downward pressing device is provided on the bearing plate. A pressing piece is provided on the downward pressing device. It also includes a detection element for detecting the running position of the fixed seat, and a controller.

[0007] The above-mentioned auxiliary material pressing device for a four-sided sewing system, wherein the lower pressing device is a double-axis cylinder, and the double-axis cylinder is signal-connected to a controller.

[0008] The above-mentioned auxiliary material pressing device for a four-sided sewing system, wherein the driving device is a cylinder with an output shaft connected to a bearing plate. A connecting plate for connecting the output shaft of the cylinder and a fixed seat is provided between the output shaft of the cylinder and the fixed seat, and the cylinder is signal-connected to a controller.

[0009] The above-mentioned auxiliary material pressing device for a four-sided sewing system, wherein the guiding mechanism includes a slide rail arranged along the length direction of a longitudinal plate and a slider arranged on the slide rail.

[0010] The above-mentioned auxiliary material pressing device for a four-sided sewing system, wherein the detection element includes a bracket arranged on a fixed seat and a distance sensor arranged on the bracket.

[0011] The above-mentioned auxiliary material pressing device for a four-sided sewing system is provided with a first adjustment cavity on a fixing plate for adjusting the connection position between the bearing plate and the fixing plate, a screw hole on the bearing plate, a first adjustment bolt and a first locking nut in the first adjustment cavity, a second adjustment cavity on the bearing plate for adjusting the connection position between the double-axis cylinder and the bearing plate, a second adjustment bolt and a second locking nut in the second adjustment cavity.

[0012] The beneficial effect of the auxiliary material pressing device for a four-sided sewing system of the present utility model is that by arranging a longitudinal plate on a base, a guiding mechanism, a fixed seat on the longitudinal plate, arranging a fixing plate at the bottom of the fixed seat, arranging a bearing plate on the fixing plate, arranging a lower pressing device on the bearing plate, and arranging a pressing piece on the lower pressing device, when sewing the first side, the first side will not retract too much (the feed dog and the pressing plate are not synchronized), thus causing the situation that when sewing the end of the fourth side, it cannot coincide with the start of the first side and defective products occur. The finished product rate and high-quality product rate of the sewn products are greatly improved, and beautiful products can be sewn without reducing the sewing speed during starting and cornering, thereby increasing the work efficiency by more than 30%.
