[0002] In the garment manufacturing process, hemming trousers is an indispensable step. In the past, it was all done by hand. Later, when manual operation could not keep up with the pace, people began to think about creating special equipment. After continuous experimentation and improvement, the traditional hemming equipment for trousers emerged.

[0003] Traditional trouser hem rolling equipment mainly consists of feeding, folding, sewing, and transmission. When working, the trouser hem is straightened and inserted into the inlet. The feeding roller rotates, carrying the fabric forward. When it passes the folding baffle, the edge of the trouser hem is folded to a fixed width. Then, it is sewn together with a sewing machine.

[0004] With the development of the garment industry, people have higher and higher requirements for clothing, and the hem of trousers has also received attention. However, traditional trouser hem rolling equipment often suffers from positional deviations because it requires manual alignment of the starting position of the hem. In addition, traditional trouser hem rolling equipment cannot change the width of the hem, making it unsuitable for the production development of the garment industry. Therefore, a new trouser hem rolling equipment is proposed to solve the above problems. Utility Model Content

The right side of the hem-rolling baffle 12 is fixedly connected to the motor box 7, and the motor 19 is rotatably connected inside the motor box 7. The output end of the motor 19 is fixedly connected to the upper rotating shaft 21, and the outer side of the upper rotating shaft 21 is fixedly connected to the upper roller 20. When the motor 19 in the motor box 7 is started, the motor 19 rotates and drives the upper rotating shaft 21 and the upper roller 20 to rotate. The upper roller 20 and the lower roller 14 cooperate with each other to realize automatic hem-rolling and further prevent possible positional deviations in the hem-rolling process of the trouser hem, ensuring the consistency of the hem-rolling.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A fixed frame 9 is fixedly connected to the top of the workbench 1. Multiple limiting holes 8 are provided on both sides of the top of the fixed frame 9. An adjusting plate 10 is slidably connected inside the fixed frame 9. Limiting pins 13 are provided on both sides of the adjusting plate 10. The adjusting plate 10 slides inside the fixed frame 9. With the help of the limiting holes 8 and the limiting pins 13 on both sides, when it is necessary to roll up the trouser hem of different sizes or styles, simply pull the adjusting plate 10 to make the limiting pin 13 disengage from the current limiting hole 8. When adjusted to the appropriate position, the limiting pin 13 on the adjusting plate 10 will engage with the current limiting hole 8 to complete the positioning. A stop plate 16 is fixedly connected to one side of the limiting pin 13. A spring 17 is fixedly connected to one side of the stop plate 16. The limiting pin 13, the stop plate 16 and the spring 17 cooperate to form a limiting self-locking device. With the help of the limiting holes 8 on the fixed frame 9, the width of the trouser hem can be adjusted to meet the production needs of different trouser hem rolling.

[0034] Reference Figure 3 The adjusting plate 10 has a spring hole 18 inside, and the stop plate 16 is slidably connected inside the spring hole 18. The spring hole 18 inside the adjusting plate 10 provides sliding space for the stop plate 16, allowing the stop plate 16 to move along a fixed trajectory when pulled or reset, thus preventing the stop plate 16 from shaking or shifting.

[0035] Reference Figure 1 and Figure 4The workbench 1 is equipped with a positioning shaft 15 inside. The lower roller 14 is rotatably connected to the outside of the positioning shaft 15. The lower roller 14 is vertically aligned with the upper roller 20. The positioning shaft 15 inside the workbench 1 is for the convenience of installing the lower roller 14. The lower roller 14 is vertically aligned with the upper roller 20. The two work together to ensure that the trouser leg is evenly stressed during the conveying process and will not deviate or skew. This ensures that the starting position of the rolled edge of the trouser leg will not deviate during the sewing process.

[0036] Reference Figure 1 and Figure 4 A protective box 5 is fixedly connected to the left side of the rolled edge baffle 12. The protective box 5 is fixedly connected to the outside of the upper roller 20. The protective box 5 fixed to the left side of the rolled edge baffle 12 can play a safety protection role. When the upper roller 20 is rotating, the protective box 5 covers it, which can prevent the operator from accidentally touching the rotating roller and getting injured, making the operation process safer.

[0037] Reference Figure 1 A sewing machine 6 is fixedly connected to the top of the workbench 1. After the trouser leg is rolled up by the hem rolling structure, the rolled hem can be sewn directly.

[0038] Reference Figure 1 Each of the four corners at the bottom of the workbench 1 is fixedly connected to a support column 11, which provides a stable support point for the entire workbench 1 and prevents the workbench 1 from shaking during operation.

[0039] Reference Figure 1 and Figure 2 One end of the adjusting plate 10 is hook-shaped and fits against the top of the hem rolling plate 3. The adjusting plate 10 is designed to be hook-shaped and fits against the top of the hem rolling plate 3. It can guide and limit the trouser leg when it enters the hem rolling. The hook-shaped part fits against the surface of the hem rolling plate 3. When the trouser leg fabric passes by, it can slide naturally towards the hem rolling plate 3 along the arc of the hook-shaped structure, avoiding wrinkles or deviation of the fabric at the entrance.

[0040] Working principle: When the starting position of the hem needs to be adjusted, a hem-rolling inlet base plate 2 is set on the workbench 1, and a hem-rolling baffle 12 is fixed to one side of the hem-rolling inlet base plate 2. A hem-rolling plate 3 is fixed to the top of the hem-rolling baffle 12, and the hem-rolling plate 3 is suspended above the hem-rolling inlet base plate 2. Through the cooperation between the hem-rolling inlet base plate 2, the hem-rolling baffle 12, and the hem-rolling plate 3, the trouser leg is guided into the equipment along a set path, allowing the starting position of the hem to be quickly aligned. An upper roller 20 is set on one side of the hem-rolling baffle 12... The lower roller 14 inside the workbench 1 is in a vertically aligned state. When the fabric enters through the hem-rolling inlet plate 2, the hem-rolling plate 3 will complete the hem-rolling. At the same time, the hem-rolling baffle 12 and the hem-rolling plate 3 will cooperate to align the starting position of the hem-rolling of the trouser leg. Then the sewing machine 6 will sew the hem-rolled position. The sewn hem-rolled position will be clamped by the upper roller 20 and the lower roller 14 to further fix the starting position of the hem-rolling. After the motor 19 is started, while driving the hem-rolling transmission, it also prevents possible deviations in the starting position during the hem-rolling and sewing.

[0041] When it is necessary to adjust the hem width, limit pins 13 are provided on both sides of one end of the adjusting plate 10. A stop plate 16 is provided on one side of the limit pin 13, and a spring 17 is fixed on one side of the stop plate 16. The limit pins 13, the stop plate 16 and the spring 17 cooperate to form a limit self-locking device. At the same time, multiple limit holes 8 are provided on both sides of the top of the fixed frame 9. The adjusting plate 10 slides inside the fixed frame 9. When it is necessary to hem trouser legs of different sizes or styles, simply pull the adjusting plate 10 to disengage the limit pins 13 from the current limit holes 8. After adjusting to the appropriate position, the limit pins 13 on the adjusting plate 10 will engage with the current limit holes 8 to complete the width adjustment of the hem width of the trouser legs, so as to adapt to different hem production needs.
