Detailed Implementation

[0022] The present application will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present application can be more easily understood and mastered.

[0023] Reference Figures 2-3 This embodiment of a sleeve folding machine includes a body 5, a transverse moving platform 51 mounted on the body 5, a folding mechanism 52 mounted on the body 5, and a sewing machine 2 mounted on the transverse moving platform 51. The transverse moving platform 51 consists of a linear motor 511 and a mounting plate 512, wherein the sewing machine 2 is mounted on the mounting plate 512, and the linear motor 511 controls the transverse movement of the mounting plate 512 and the sewing machine 2. The folding mechanism 52 is used to fold and press the sleeve folding fabric. The folding mechanism 52 is a well-known mechanism to those skilled in the art, and its specific structure will not be described in detail in this application.

[0024] Reference Figure 2 and Figure 4 A sliding base 21 is slidably connected to the front side of the sewing machine 2 along its longitudinal direction. A drive mechanism 4 is installed on the sewing machine 2 to drive the sliding base 21 to reciprocate longitudinally. The drive mechanism 4 includes a motor 41 and a connecting rod 42. One end of the connecting rod 42 is connected to the output shaft of the motor 41, and the other end of the connecting rod 42 is threaded with a mounting bolt 44. The motor 41 in this application can be a stepper motor.

[0025] Reference Figure 2 , Figure 4 and Figure 5The drive mechanism 4 also includes a second connecting rod 43, which includes a rod body 431 and two mating rings 432 located at both ends of the rod body 431. Each of the two mating rings 432 has an integrally formed mating rod 433, which is threaded to both ends of the rod body 431. The two mating rings 432 are hinged to the screws of two mounting bolts 44. When the output shaft of the motor 41 rotates, it drives the first connecting rod 42, the second connecting rod 43, and the sliding seat 21 to reciprocate longitudinally.

[0026] Reference Figure 4 and Figure 5 A telescopic drive component 3 is installed at an angle on the bottom of the sliding seat 21. The telescopic drive component 3 includes a cylinder 31, a first block 32 connected to the output shaft of the cylinder 31, and a second block 33 detachably connected to the first block 32. A slide rail 38 is provided on the side wall of the cylinder body of the cylinder 31, and the first block 32 is slidably connected in the slide rail 38 along the length direction of the cylinder 31. A middle pressure foot 22 is installed at the bottom of the second block 33.

[0027] Reference Figure 5 and Figure 6 The second block 33 has four first adjustment slots 34, and the first block 32 has four first adjustment bolts 35. The screws of the four first adjustment bolts 35 pass through the four first adjustment slots 34 and are connected to the first block 32. The four first adjustment bolts 35 press the second block 33 onto the first block 32.

[0028] Reference Figure 5 and Figure 6 The middle pressure foot 22 is provided with a second adjustment groove 36, and the second block 33 is provided with a second adjustment bolt 37. The screw of the second adjustment bolt 37 passes through the second adjustment groove 36 and is connected to the second block 33. The second adjustment bolt 37 presses the middle pressure foot 22 onto the second block 33.

[0029] Reference Figures 4-6 In this application, motor 41 is electrically connected to the control system of sewing machine 2. The control system controls the rotation of motor 41 through the output signal of the encoder on the main shaft motor that drives the sewing needle, thereby controlling the up and down position of the presser foot 22. When the needle is sewing, the presser foot 22 moves down to press down on the cuff fabric. When the needle moves horizontally, the presser foot 22 moves up to separate from the cuff fabric, preventing dragging of the cuff fabric. During the sewing process of the machine head sewing the cuff of the cuff fabric, the presser foot 22 will continuously repeat the above actions.

[0030] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
