Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, and in particular to a sewing machine for garment processing. Background Technology

[0002] A sewing machine is a mechanical device used to sew fabrics, leather, or other materials together. It is widely used in garment manufacturing, home decoration, and handicraft production. Depending on the application and needs, sewing machines can be divided into industrial sewing machines and household sewing machines. Industrial sewing machines are typically powerful and fast, suitable for large-scale production, while household sewing machines emphasize ease of operation and versatility.

[0003] The existing technology has the following problems: Existing sewing machines typically feed the sewing thread directly. However, due to the conical structure of the sewing thread spool, the thread moves up and down on the outside of the spool when pulled out. Since the spool rotates at a constant speed, the thread is pulled out a greater length at the bottom and a shorter length at the top. This results in the thread being sometimes taut and sometimes slack, leading to unstable sewing results. Furthermore, excessive tension can cause the thread to break. Utility Model Content

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-6 As shown, a sewing machine for garment processing includes a base plate 1. A sewing machine body 2 is fixedly connected to the upper side of the base plate 1. A fixing rod 3 is fixedly connected to the upper side of the sewing machine body 2 near the left side. A fixing seat 6 is fixedly connected to the rear side of the fixing rod 3 near the left side. A fixing mechanism 5 is movably sleeved on the inner side of the fixing seat 6. A tension adjustment mechanism 4 is fixedly connected to the rear side of the fixing mechanism 5. The tension adjustment mechanism 4 includes a base plate 41. Three fixed pulleys 42 are rotatably connected to the rear side of the base plate 41 near the upper and lower sides. Two support rods 43 are rotatably connected to the bottom rear side of the base plate 41 near the left and right sides. A movable wheel 44 is rotatably connected to the front side of the support rod 43. Two electric push rods 45 are rotatably connected to the left and right sides of the movable wheel 44. The front side of the electric push rods 45 is rotatably connected to the upper side of the base plate 41 near the left and right sides.

[0018] It should be noted that the fixed rod 3 is used to hold the spool of sewing thread, the fixed pulley 42 is used to position the sewing thread so that the position of the sewing thread remains unchanged when it enters and exits the moving wheel 44, and the electric push rod 45 controls its own length so that the electric push rod 45 pushes the moving wheel 44 to move, thereby adjusting the tension of the sewing thread.

[0019] like Figure 5 As shown, a tension detector 46 is fixedly connected to the upper side of the base plate 41 near the rear side, and a horn tube 47 is fixedly connected to the upper side of the base plate 41 near the front side.

[0020] It should be noted that the tension detector 46 is a three-pulley tension detection device. The tension detector 46 is used to detect the tension of the sewing thread. The horn tube 47 is used to prevent the sewing thread entering the tension detector 46 from swinging left and right and up and down due to the influence of the thread spool, which would affect the tension detection result of the tension detector 46. The tension detector 46 is existing technology and will not be described in detail here. The entire device is connected to the control device in the form of a data cable to coordinate the operation of all electrical components.

[0021] like Figure 4 , Figure 5 As shown, the fixing mechanism 5 includes a locking platform 51. The rear and upper sides of the locking platform 51 are fixedly connected to the inner middle of the base plate 41. The outer side of the locking platform 51 is movably sleeved on the inner side of the fixing seat 6. Several evenly distributed fixing components 52 are movably sleeved on the inner sides of the left and right walls of the fixing seat 6. The fixing components 52 include insert blocks 521. The outer side of the insert blocks 521 is movably sleeved in the insertion holes opened on the left and right sides of the locking platform 51. Limiting tubes 522 are movably sleeved on the inner sides of the left and right walls of the fixing seat 6. A first spring 523 is movably sleeved on the inner sides of the left and right walls of the fixing seat 6, and the first spring 523 is located between the insert block 521 and the limiting tube 522.

[0022] It should be noted that the insert 521 is triangular with the inclined surface facing the rear, so that the card holder 51 can be directly inserted into the fixing seat 6. Relying on the action of the first spring 523, the insert 521 moves on its own. When the insertion holes on the left and right sides of the card holder 51 are aligned with the insert 521, the insert 521 resets itself, thus fixing the card holder 51.

[0023] like Figure 4 As shown, a fixing ring 524 is fixedly connected to the inner side of the left and right walls of the fixing base 6, and a second spring 526 is movably sleeved on the inner side of the left and right walls of the fixing base 6. A pull rod 525 is movably sleeved on the inner side of the limiting tube 522, and the side of the pull rod 525 near the card table 51 is fixedly connected to the side of the insert block 521 near the first spring 523.

[0024] It should be noted that the second spring 526 is located between the fixing ring 524 and the limiting tube 522. When the side of the limiting tube 522 away from the card table 51 is unrestricted, the fixing ring 524 pushes the limiting tube 522, causing the limiting tube 522 to pull the insert block 521, so that the insert block 521 no longer fixes the card table 51.

[0025] like Figure 4 , Figure 6 As shown, two rotating seats 53 are rotatably connected to the bottom of the left and right sides of the fixed seat 6. A baffle 54 is rotatably connected to the upper side of each of the two rotating seats 53. Two retaining sleeves 55 are fixedly connected to the left and right sides of the fixed seat 6 near the outer edge. The outer side of the baffle 54 is movably sleeved on the inner side of the retaining sleeve 55.

[0026] It should be noted that the baffle 54 is used to limit the side of the limiting tube 522 away from the clamping table 51, and the clamping sleeve 55 is used to fix the baffle 54. Rotating the baffle 54 causes the rotating seat 53 to disengage from the clamping sleeve 55, thereby no longer fixing the limiting tube 522.

[0027] like Figure 4 , Figure 6 As shown, torsion springs are provided at the positions between the bottom of the two rotating seats 53 and the fixed seat 6.

[0028] It should be noted that the torsion spring is used to drive the rotary seat 53, so that the baffle 54 is always inside the retaining sleeve 55 in the initial state and will not come out of the retaining sleeve 55 on its own.

[0029] like Figure 6 As shown, rubber pads are fixedly connected to the upper and rear sides of the fixing base 6.

[0030] It should be noted that the rubber pad is used to fill the gap between the fixed seat 6 and the base plate 41 to prevent the parts from moving due to manufacturing tolerances.

[0031] The working principle of this utility model is as follows: First, the fixed pulley 42 is used to position the sewing thread, so that the position of the sewing thread remains unchanged when it enters and exits the moving wheel 44. The electric push rod 45 controls its own length, so that the electric push rod 45 pushes the moving wheel 44 to move, thereby adjusting the tension of the sewing thread. The tension detector 46 is a three-pulley tension detection device. The tension detector 46 is used to detect the tension of the sewing thread. The horn tube 47 is used to prevent the sewing thread entering the tension detector 46 from swinging left and right and up and down due to the influence of the thread spool, which would affect the tension detection result of the tension detector 46. The tension detector 46 detects the tension of the sewing thread, and then the electric push rod 45 drives the moving wheel 44 to move, thereby adjusting the tension of the sewing thread. The adjustment is convenient and the operation is convenient, ensuring the yield of sewing products and avoiding the problem of the sewing thread breaking due to excessive tension. Finally, the insert block 521 is triangular with the inclined surface facing the rear, so that the locking table 51 can be directly pressed into the fixed seat 6, relying on the first spring 52. The function of 3 is to allow the insert block 521 to move independently. When the insertion holes on the left and right sides of the card table 51 are aligned with the insert block 521, the insert block 521 automatically resets, fixing it to the card table 51. The second spring 526 is located between the fixing ring 524 and the limiting tube 522. When the side of the limiting tube 522 away from the card table 51 is unrestricted, the fixing ring 524 pushes the limiting tube 522, causing the limiting tube 522 to pull the insert block 521, thus causing the insert block 521 to no longer fix the card table 51. The baffle 54 is used to... The limiting tube 522 is limited on the side away from the card table 51. The retaining sleeve 55 is used to fix the baffle 54. Rotating the baffle 54 causes the rotating seat 53 to disengage from the retaining sleeve 55, thus no longer fixing the limiting tube 522. By directly pressing the card table 51 into the fixed seat 6, the tension adjustment mechanism 4 is quickly fixed on the fixed seat 6. By rotating the baffle 54, the insert block 521 quickly releases its fixation on the card table 51. It is easy to install and disassemble, and convenient to maintain the tension adjustment mechanism 4.
