Description

Technical Field

[0001] This utility model relates to the field of textile machinery, and in particular to a quilting machine. Background Technology

[0002] Quilting is a sewing process in which layers of textile materials and / or other textiles are joined to create decorative and functional compressible surfaces. Quilting machines typically have a main beam on which the sewing head is mounted to sew the textile, forming a series of overlapping surfaces. During sewing, the unwinding side is usually sewn first, followed by the unwinding side. When sewing on the unwinding side, the fabric tightens due to the tension of the stitches, creating a series of embroidered stitches. If the distance between the sewing head and the unwinding side is the same, there will be a significant deviation in the embroidery position near the unwinding side. Inaccurate positioning of the embroidered fabric at the unwinding side can lead to overlapping or irregular stitches, affecting the aesthetics of the design and failing to achieve the desired effect. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a quilting machine with staggered machine heads, resulting in finer and more efficient quilting stitches.

[0004] The technical solution adopted is as follows:

[0005] A quilting machine includes a main beam, one side of which is a take-up side and the other side is an unwinding side. Several machine heads are provided on both sides of the main beam. The distance between the machine heads on the take-up side is a reference distance. The distance between the machine heads on the unwinding side is equal and each distance is greater than the reference distance. The machine heads on both sides of the main beam are staggered.

[0006] Typically, the winding side is equipped with a winding mechanism, and the unwinding side is equipped with an unwinding mechanism.

[0007] Furthermore, the head spacing of the unwinding side machine head is increased by 0.6-0.5 mm per head compared to the head spacing of the winding side machine head.

[0008] Furthermore, the winding mechanism is provided with a winding roller for winding, and the unwinding mechanism is provided with an unwinding roller for unwinding.

[0009] Furthermore, the winding mechanism and the unwinding mechanism may be provided with only one lead screw or two lead screws respectively, and the lead screw is provided with a movable lead screw slider that drives the winding mechanism and the unwinding mechanism to move left and right.

[0010] Furthermore, a guide rail with a guide slider is provided below the winding mechanism and the unwinding mechanism. The winding mechanism and the unwinding mechanism are fixedly connected to the lead screw slider and the guide rail slider. The frame is also provided with a driver that drives the first and second lead screws to move the lead screw slider.

[0011] Furthermore, the machine head may be equipped with rope embroidery or bead embroidery devices.

[0012] Furthermore, a transverse positioning rod is provided on each side of the main beam, and the machine head is positioned at the same height on the positioning rod.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0014] This invention provides a quilting machine, including a main beam and machine heads. The main beam has a take-up side and an unwinding side on opposite sides. Several machine heads are positioned on both sides of the main beam. The distance between the machine heads on the unwinding side is increased compared to the distance between the machine heads on the take-up side. Since the fabric sewn on the unwinding side will shrink due to the tension of the stitches, increasing the distance between the machine heads on the unwinding side can relatively offset this shrinkage. This results in more accurate stitches at the take-up side, leading to more even and aesthetically pleasing quilting. Furthermore, the staggered arrangement of the machine heads on both sides increases the number of machine heads and shortens the distance between them, resulting in finer quilting stitches. Simultaneous operation of multiple machine heads also increases speed and efficiency. Attached Figure Description

[0018] The components include: main beam 1, machine head 2, winding mechanism 3, unwinding mechanism 4, guide rail 5, and lead screw 6. Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] refer to Figure 1 , 2 3. A quilting machine includes a main beam 1, with one side of the main beam 1 being a take-up side and the other side being an unwinding side. The take-up side typically has a take-up mechanism 3, and the unwinding side has an unwinding mechanism 4. Several machine heads 2 are provided on both sides of the main beam 1. The distance between the machine heads 2 on the take-up side is a reference distance, and the distance between the machine heads 2 on the unwinding side is equal, with each distance greater than the reference distance. The machine heads 2 on both sides of the main beam 1 are staggered to facilitate rapid quilting of qualified quilted embroidery. The distance between adjacent machine heads is the distance between adjacent machine heads. The specific amount by which the distance between the unwinding side machine heads is greater than the distance between the take-up side machine heads can be determined according to the fabric and quilting process.

[0021] Furthermore, the head spacing of the winding side machine heads is equal, and the head spacing is the reference head spacing; the head spacing of the unwinding side machine heads is also equal, so that a more regular and beautiful pattern can be obtained during sewing.

[0022] Furthermore, a working platform is provided at one end of the frame 2, and the winding mechanism 3 and the unwinding mechanism 4 are located on the working platform. The winding mechanism 3 and the unwinding mechanism 4 are respectively equipped with a winding roller and an unwinding roller. The winding and unwinding are combined to drive the fabric to move and form embroidery.

[0023] Furthermore, based on practical considerations and to accommodate most quilting situations, it is preferable that the distance between each head of the unwinding side of the sewing machine is increased by 0.6-0.5 mm compared to the distance between each head of the rewinding side. Generally, the sewing machine on the rewinding side begins sewing first. During the sewing process, the fabric tightens due to the tension of the needle and thread, causing deviations in the embroidery position when the unwinding side is sewing; the embroidery stitches may overlap or deviate from the desired position. To reduce this error, the distance between each head of the unwinding side of the sewing machine is increased by 0.6-0.5 mm to compensate for the increased fabric tension.

[0024] As a further preferred embodiment, the winding mechanism 3 and the unwinding mechanism 4 may be connected by a single lead screw or by separate lead screws 6. The lead screw 3 is equipped with a movable slider that drives the winding mechanism 3 and the unwinding mechanism 4 to move left and right. By having lead screws 6 positioned below the winding and unwinding mechanisms, the load-bearing capacity of each lead screw is lighter than that of a single lead screw, and the force is more evenly distributed, resulting in faster and more efficient movement of the winding and unwinding mechanisms.

[0025] As a further preferred embodiment, a guide rail 5 with a guide slider is provided below the winding mechanism 3 and the unwinding mechanism 4. The winding mechanism 3 and the unwinding mechanism 4 are fixedly connected to the lead screw slider and the guide rail slider. The frame is also equipped with a driver that drives the lead screw to move the lead screw slider. While the driver drives the lead screw slider to move, the guide rail slider also moves accordingly. The guide rail slider and the lead screw slider are located together below the mechanism, making the movement of the winding and unwinding mechanisms smoother. The winding roller on the winding mechanism and the unwinding roller on the unwinding mechanism cooperate to move the fabric longitudinally, while the sliders under the winding and unwinding mechanisms drive the fabric to move left and right, forming fine and neat embroidery stitches.

[0026] As a further preferred option, the embroidery head 2 can be equipped with cord embroidery or bead embroidery devices. Each embroidery head works independently, and various different devices can be set on different embroidery heads 2 as needed to make the embroidery on the quilted fabric richer and more exquisite.

[0027] As a further preferred embodiment, a transverse positioning rod is provided on each side of the main beam, and the sewing machine head is positioned at the same height on the positioning rod. Setting the positioning rod ensures that the height of the sewing machine head is consistent, the needle frequency is consistent, the stitches are neater, the sewing machine head works synchronously, and the error is smaller.

[0028] This utility model provides a quilting machine, including a main beam and several sewing heads disposed on both sides of the main beam. A winding mechanism and an unwinding mechanism are respectively provided on both sides of the main beam, and the sewing heads on different sides are staggered. The staggered arrangement of the sewing heads on both sides increases the number of sewing heads and shortens the distance between them, resulting in finer quilted stitches. Multiple sewing heads working simultaneously result in faster processing time and higher efficiency. The distance between the sewing heads on the winding side is greater than that on the unwinding side, which can reduce errors caused by fabric shrinkage due to thread pulling during sewing on the unwinding side.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
