In sewing machines, the needle is in constant contact and friction with the fabric and thread during the sewing process. In this condition. If the machine is operating at high speed, the needle eye, needle tip and Friction causes a temperature increase in the areas where the thread passes through the needle. 15 This increase in temperature leads to yarn breakage and damage in synthetic fabrics. deformation, decreased stitch quality, reduced needle life, and production This can lead to a decrease in productivity. In the current state of the art, various solutions are being sought to mitigate this problem. are used.

Yarn transition zone Detailed Description of the Invention This detailed explanation describes the preferred needle cooling apparatus that is the subject of the invention. Their structures are explained solely to facilitate a better understanding of the subject. The needle cooling apparatus (A) which is the subject of the invention; the main carrier of the needle cooling apparatus (A) 25 the connecting apparatus (11) which forms the structure and contains other elements through which the body (2) is located near the needle shaft area (1) of the sewing machine, enabling the body (2) to be detachably fixed to the sewing machine. at least one connecting device (11) connecting between the body (2) and the sewing machine, needle shaft 30 that receives the movement in the region (1) through direct mechanical contact and transmits it to the micro bellows (7) 4 and at least one movement positioned between the needle shaft area (1) and the micro bellows (7). The transmission element (8) receives the motion from the transmission element (8) air that expands and compresses, pressurizing the ambient air and creating an air blast at least one located between the inlet duct (3) and the air direction duct (12) micro bellows (7) transmits the air taken from the outside environment to the micro bellows (7) and the micro bellows (7) 5 At least one air inlet duct (3) connecting between the outside environment and the pressurized at least one that prevents air from escaping back and is positioned on the airflow path valve (9) conveys the air pressurized by the micro bellows (7) to the air outlet channel (4) and at least one air outlet connected between the micro bellows (7) and the air outlet duct (4) The air guide channel (12) directs the air conveyed by the air guide channel (12) to the needle 10 (5) directing and directed to the needle (5) at the exit of the air directing channel (12). At least one air outlet duct (4) positioned in such a way, exiting from the air outlet duct (4) adjusting the amount and / or intensity of the air pulse and associated with the air outlet duct (4) It includes an air flow control element (10) positioned in the figure. In a sample application of the needle cooling apparatus (A) which is the subject of the invention; the stitching process is 15 During this time, the needle shaft region (1) moves up and down and mechanically with this region The motion is directly transmitted to the contacting motion transmission element (8). Needle shaft When region (1) moves upwards, the micro bellows (7) expands and the ambient air, Air is drawn into the system through the air inlet channel (3). The needle shaft area (1) is downward. When it moves, the micro bellows (7) is compressed by means of the motion transmission element (8), 20 The air taken into the system is pressurized. The pressurized air escapes through the valve (9) This is prevented thanks to the fact that the pressurized air only moves in the direction of the air outlet duct (4). and is conveyed through the air direction channel (12) to the air outlet channel (4). Air outlet channel (4), this air pulse passes through the needle (5) eye (13), needle tip (14) and thread passage It directs it to the region (15). Thus, in each needle movement cycle, it is short-lived and 25 By creating targeted air pulses, the presser foot (6) during the sewing process the temperature increase caused by the friction of the needle (5) going in and out of the fabric underneath is reduced. In the example application in question, the air inlet duct (3) external compressed air line It has no connection and the needle cooling apparatus (A) is not connected to external electrical power or external 30 obtained from the movement of the needle (5) alone without the need for a compressed air line It operates using mechanical energy. In a preferred application of the invention, the needle cooling apparatus (A) has an air outlet. an air duct (4) that adjusts the amount and / or intensity of the air pulse coming out of the duct. It may include an air flow control element (10). The air flow control element (10) in question contains the air an adjustable one that mechanically narrows and widens the cross-section of the outlet channel (4) It functions as a throttling element; when the cross-section is narrowed, the airflow decreases. The air flow decreases when it is expanded and increases when it is expanded. In this way, the micro bellows (7) without interfering with the stroke, the amount of air pulse directed to the needle (5) and 5 Its intensity can be adjusted; The air flow adjustment element (10) will be installed. depending on the type of fabric, fabric thickness, yarn characteristics, and machine operating speed. It can be adjusted accordingly. This allows for a lower intensity air shock in thin fabrics. By applying this method, unwanted movement on the fabric surface can be reduced; thick or In synthetic fabrics, a higher intensity air pulse is applied using needle 10. Temperatures in the region can be reduced more effectively. Another preferred application of the invention is the needle cooling apparatus (A), body (2) Through the connecting device (11) on it, it can be connected to existing sewing machines, the main machine no permanent changes to the body or standard stitching mechanism are required It can be assembled in a way that allows it to be disassembled without leaving any gaps. 15 In another preferred application of the invention, the air outlet duct (4) can be used to release the air pulse. at least one of the needle's (5) eye (13), needle tip (14) and threading area (15) It can be positioned to direct direction. The invention relates to sewing machines used in the textile and garment manufacturing industry. It is applicable. The mechanical energy obtained from the needle movement when the stitching process begins is 20. Air pulses created by the needle reduce the temperature (5) during high-speed operation. to prevent yarn breakage, reduce deformation in synthetic fabrics, and It contributes to maintaining the quality of the stitching. The invention applies to the application described above. not limited to this form, but also in different types of sewing machines that work with needle movement. It is applicable. 25
