Description

Technical Field

[0001] This invention relates to the field of sewing machine technology, specifically to an integrated sewing machine with continuous heating wire wiring. Background Technology

[0002] In the automated production process of heating products such as electric blankets and heated seat cushions, the sewing of heating wires is generally done using a zigzag pattern sewing machine or a herringbone rotary sewing machine. The sewing fabric moves according to the design pattern, and the sewing machine needle bar moves up and down while swinging left and right to form N-stitch, thereby attaching the heating wires of this pattern to the sewing fabric.

[0003] With the continuous advancement of automation and intelligentization, sewing equipment is also constantly being upgraded. In the sewing of heating wires, there are automatically controlled heating wire sewing template machines. These machines lay the heating wire mesh flat and fix it on a template. According to a preset pattern, the template is moved to sew the heating wire onto the mesh. However, due to space limitations, these template machines are mainly used for small to medium-sized fabrics such as electric blankets and heating pads, and cannot be used for sewing long rolls of heating mesh similar to those used in home underfloor heating. With the increasing demand for home underfloor heating and industrial insulation, there is an urgent need for a continuous wiring sewing machine for heating wires. Therefore, we propose an integrated machine for continuous wiring sewing of heating wires. Summary of the Invention

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] A heating wire sewing machine is a specialized machine used to sew heating wires into heating products such as electric blankets, heating bases, and insulation materials. Existing template machines have limited space and are mainly used for small to medium-sized fabrics such as electric blankets and heating bases; they cannot be used for sewing long rolls of heating mesh fabric similar to those used for home floor heating.

[0033] Therefore, please refer to Figures 1-6 The present invention provides an integrated sewing machine for continuous wiring of heating wire.

[0034] Specifically, the integrated sewing machine for continuous wiring of heating wire includes a base 1, which consists of a frame and mounting components, and is placed on the ground to support the machine. A sewing mechanism 2 is mounted on one axis of the base 1, used to sew the heating wire onto the fabric. A feeding mechanism 3 is located on one side of the base 1 for feeding the fabric to be sewn. A winding mechanism 4 is located on the other side of the base 1 for winding the sewn material. A wire feeding mechanism 5 is located outside the base 1 for feeding the heating wire. A pressing mechanism 6 is located inside the base 1 for flattening the fabric.

[0035] In this embodiment, the sewing mechanism 2 includes a bracket 21, one end of which is fixedly mounted on the machine base 1, and the other end of which is connected to a sewing machine head 22. This sewing mechanism 2 uses a sewing template machine, which will not be described in detail here.

[0036] Please see Figure 1 The sewing mechanism 2 has its back facing right and its head facing left. The feeding mechanism 3 is located in front of the sewing mechanism 2, and the winding mechanism 4 is located behind the sewing mechanism 2, with the feeding mechanism 3 and winding mechanism 4 being symmetrical to each other. There are two pressing mechanisms 6, which are symmetrically distributed about the axis of the machine base 1, and are located between the feeding mechanism 3 and the winding mechanism 4. During sewing, the feeding mechanism 3 unwinds the fabric, and after being flattened by two of the pressing mechanisms 6, the fabric is fixed on the winding mechanism 4, which provides power to wind the fabric. During the winding process, the fabric passes under the sewing machine head 22, and the sewing machine head 22 sews the heating wire onto the fabric, thus enabling continuous sewing of long rolls of heated mesh fabric.

[0037] Furthermore, a tensioning wheel assembly 23 is provided on the support 21. The tensioning wheel assembly 23 consists of multiple tensioning wheels and is used to tension and guide the heating wire. The wire feeding mechanism 5 is located on the right side of the machine base 1. The heating wire in the wire feeding mechanism 5 is fed from above the support 21. After being tensioned and guided by the tensioning wheel assembly 23, it enters the sewing machine head 22, where it is sewn onto the fabric.

[0038] In this embodiment, the thread feeding mechanism 5 includes a base 51, which can be fixedly installed on the right side of the machine base 1 or independently placed on the ground. A thread feeding motor 52 is fixedly installed on the base 51, and a thread feeding drum 53 is fixedly installed at the output end of the thread feeding motor 52. The thread feeding drum 53 is rotatably installed on the base 51 through bearings. The thread feeding drum 53 is used to wind the heating wire. During sewing, the thread feeding motor 52 drives the thread feeding drum 53 to rotate, thus feeding the thread at a uniform speed. In traditional heating wire sewing machines, the heating wire spool is installed on one side of the machine head. However, due to space limitations, only a small spool can be used, requiring frequent replacement of the heating wire spool, which restricts the improvement of automation. This device uses a large spool to feed the heating wire, which can achieve continuous follow-up thread feeding and reduce the waste of heating wire.

[0039] In this embodiment, the feeding mechanism 3 includes a feeding frame 31, which is installed on the front side of the machine base 1. A feeding cylinder 32 is rotatably mounted on the feeding frame 31. The feeding cylinder 32 is used to wrap the fabric. The feeding cylinder 32 cooperates with the winding mechanism 4 to realize the feeding of the fabric before sewing and the winding of the fabric after sewing, so that the sewing process can be carried out without interruption, which is convenient for processing long roll materials.

[0040] In this embodiment, the winding mechanism 4 includes a winding frame 41, which is mounted on the base 1. A winding motor 42 is fixedly mounted on the winding frame 41, and a winding drum 43 is fixedly mounted on the output end of the winding motor 42. The winding motor 42 provides power for the rotation of the winding drum 43 to realize the winding of the sewn material. During the winding process, the other end of the fabric will automatically drive the unwinding drum 32 to rotate, thereby realizing the unwinding of the fabric.

[0041] In this embodiment, both pressing mechanisms 6 include a fixed frame 61, which is installed on the inner wall of the machine base 1. A lower pressing roller 62 is rotatably mounted on the surface of the fixed frame 61 via a bearing. An adjustment component 64 is provided on the top of the fixed frame 61, and an upper pressing roller 63 is connected to the adjustment component 64. The highest point of the outer circle of the lower pressing roller 62 is flush with the top surface of the machine base 1. In use, the fabric passes between the lower pressing roller 62 and the upper pressing roller 63, and the lower surface of the fabric can contact the top surface of the machine base 1, which facilitates the sewing machine head 22 to sew the fabric.

[0042] In this embodiment, the adjustment component 64 is used to adjust the height of the upper pressure roller 63 so that the distance between the upper pressure roller 63 and the lower pressure roller 62 can adapt to the thickness of the fabric. Specifically, the adjustment component 64 includes an electric push rod 641, which is fixedly installed on the top of the fixed frame 61. A sliding plate 642 is fixedly installed at the output end of the electric push rod 641. The sliding plate 642 is slidably installed on the fixed frame 61, and the upper pressure roller 63 is rotatably installed on the sliding plate 642 through a bearing. The electric push rod 641 can drive the sliding plate 642 to move up and down, thereby driving the upper pressure roller 63 to move up and down, realizing the adjustment of the distance between the upper pressure roller 63 and the lower pressure roller 62.

[0043] Please see Figure 2 One of the pressing mechanisms 6 is equipped with a conveying motor, which drives one of the lower pressing rollers 62 to rotate, thereby realizing the main conveying of materials. This ensures that the movement of the fabric does not rely solely on the winding motor 42 in the winding mechanism 4, increasing the power during the movement of the fabric and thus preventing the fabric from being torn.

[0044] In use, the continuous wiring sewing machine of the present invention first pulls the heating wire and the fabric, so that the heating wire passes through multiple tension rollers in the tension roller group 23 in sequence and enters the sewing machine head 22. One end of the fabric is pulled out from the feed tube 32 and passes through the upper pressure roller 63 and the lower pressure roller 62 in the two pressing mechanisms 6 in sequence, and is finally fixed on the take-up drum 43.

[0045] Then, the electric push rod 641 is activated. The output end of the electric push rod 641 drives the sliding plate 642 to move downward. The sliding plate 642 drives the upper pressure roller 63 to move downward, so that the upper pressure roller 63 presses against the fabric.

[0046] Finally, the feed motor 52 and the take-up motor 42 are started. The output of the feed motor 52 drives the feed drum 53 to rotate, feeding the heating wire at a uniform speed. The output of the take-up motor 42 drives the take-up drum 43 to rotate, taking up one end of the fabric. The other end of the fabric automatically drives the feed drum 32 to rotate, thus unwinding the fabric. During the winding process, the sewing machine head 22 sews the heating wire onto the fabric.
