DETAILED DESCRIPTION

[0024] The following is a detailed description of a special clothing fabric sewing device provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative methods to implement them; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the utility model provides a fabric sewing device for processing special clothing fabrics, comprising: a working frame 1; an L-shaped baffle 3, which is arranged on the working frame 1; an adjusting part 4, which is arranged on the working frame 1 and is located on one side of the L-shaped baffle 3; a pressing plate 5, which is slidably arranged on the side wall of the L-shaped baffle 3; a plurality of pulleys 7, which are movably arranged at the bottom of the pressing plate 5 and distributed along the length of the pressing plate 5; a groove 6, which is arranged on the working frame 1 and is close to the L-shaped baffle 3; and a driving part 14, which is arranged in the groove 6.

[0026] A sewing machine is arranged on the work frame 1, and an L-shaped baffle plate 3 is located at the bottom of the sewing machine. High-precision tension sensors are installed on the feeding path of the fabric. These sensors can monitor in real time the tension to which the fabric is subjected before and after entering the sewing area. The types of sensors may include but are not limited to optical, magnetic or mechanical types. The data of the tension sensor is connected to the control system of the adjustment unit 4 and the drive unit 14 to form a closed-loop feedback system. This system can compare the currently detected fabric tension with the preset ideal tension value, and automatically adjust the adjustment unit 4 and the drive unit 14 to maintain the constant fabric tension. By setting the pulley 7, wear-resistant and low-friction coefficient materials should be selected, such as engineering plastics such as nylon, stainless steel or oil-containing bearing steel, to reduce wear and noise.

[0027] like Figure 2 and Figure 5 As shown, the adjusting part 4 also includes: an adjusting frame 41, which is arranged on the working frame 1; a stepping motor 44, which is arranged on the top of the adjusting frame 41; a connecting bar 43, which is arranged in the adjusting frame 41, and one side of the connecting bar 43 passes through the adjusting frame 41 and is connected to the pressing plate 5.

[0028] By setting a connecting strip 43, the connecting strip 43 is a part of the adjusting part 4, one end of which is connected to the pressing plate 5, and the other end is indirectly connected to the stepping motor 44 through the threaded rod 42, so as to transmit power and motion, so that the rotational motion of the stepping motor 44 is converted into the up and down movement of the pressing plate 5.

[0029] like Figure 5 As shown, it also includes: a threaded rod 42, which is arranged in the adjustment frame 41, and the top of the threaded rod 42 passes through the adjustment frame 41 and is connected to the output end of the stepping motor 44; a connecting strip 43 is threadedly sleeved on the threaded rod 42.

[0030] By setting a stepper motor 44, the output end of the stepper motor 44 and the threaded rod 42 are fixed. When the stepper motor 44 is operated by an external current, the output end of the stepper motor 44 generates a rotational force, driving the threaded rod 42 to generate synchronous movement, thereby providing a power source for the rotation of the threaded rod 42.

[0031] like Figure 2 and Figure 4 As shown, the driving part 14 also includes: a plurality of support rods 13, which are arranged in the groove 6 and distributed along the length of the groove 6, and the support rods 13 are hollow; a telescopic rod 12, which is movably sleeved in the support rod 13; and a tension spring 2, which is arranged in the support rod 13.

[0032] The cloth contacts the rotating roller 11, driving the rotating roller 11 to move downward, causing the U-shaped frame 9 to move downward, causing the telescopic rod 12 to move in the support rod 13, squeezing the tension spring 2, automatically adapting to the tension change of the cloth, and maintaining a constant tension during the sewing process.

[0033] like Figure 4 As shown, it also includes: one side of the tension spring 2 is fixedly connected to the bottom of the inner cavity of the groove 6, and the other side is fixedly connected to the bottom of the telescopic rod 12, and the tension spring 2 is perpendicular to the bottom of the telescopic rod 12 connected to it.

[0034] By setting the tension spring 2, the tension spring 2 is set in the support rod 13, one end of which is fixed to the bottom of the groove 6 and the other end is connected to the telescopic rod 12, providing a dynamic restoring force, so that the telescopic rod 12 can stably extend and retract under the action of pressure and automatically reset when there is no power input.

[0035] like Figure 4 As shown, it also includes: a U-shaped frame 9, which is arranged on the top of the telescopic rod 12; a driving motor 10, which is arranged in the U-shaped frame 9; a rotating roller 11, which is rotatably arranged in the U-shaped frame 9; and the output end of the driving motor 10 is connected to one side of the rotating roller 11.

[0036] By setting the rotating roller 11, a variable friction material can be used to quickly adapt to the friction required by different fabrics, ensuring that the fabrics move forward stably and evenly.

[0037] like Figure 4 As shown, it also includes: a limit block 8, which is arranged in the groove 6, and the limit block 8 is located above the support rod 13.

[0038] By setting the limit block 8, the limit block 8 is set in the groove 6 and located above the support rod 13, so as to limit the movement range of the telescopic rod 12, prevent it from exceeding the predetermined stroke, protect the equipment from damage caused by excessive extension or compression, and ensure that after the tension spring 2 is compressed to a certain extent, there is still enough spare force to reset the U-shaped frame 9 at the end.

[0039] The technical solution provided by the utility model, when in use, uses an external controller to start the stepper motor 44 to drive the threaded rod 42 to rotate, so that the connecting strip 43 moves, thereby driving the pressing plate 5 to move, and after the pressing plate 5 is adjusted to a suitable height, the cloth is sent to the side wall of the L-shaped baffle 3, and at the same time, the external controller is used to start the drive motor 10 to drive the rotating roller 11 to rotate. When the cloth contacts the rotating roller 11, it will drive the U-shaped frame 9 to move downward, so that the telescopic rod 12 moves downward. In this process, the tension spring 2 is deformed, and finally the cloth moves in a straight line.

[0040] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
