[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4 This utility model provides a high-efficiency sewing device for hat wall decorations, including a mounting plate 1 and a mounting groove 2. The mounting groove 2 is opened through the mounting plate 1. An adjustment mechanism 3 is provided on the upper part of the mounting plate 1. A limiting mechanism 6 is provided in the mounting groove 2 through the adjustment mechanism 3 for limiting and conveying the decoration. Guide rails 4 are installed on the mounting plate 1 on the left and right sides of the mounting groove 2. A sewing station 5 is slidably installed on the guide rails 4. A pressing mechanism 7 is provided in the mounting groove 2 on the left and right sides of the limiting mechanism 6 for conveying and pressing the decoration with the limiting mechanism 6. A sewing machine is matched to the outside of the sewing station 5.

[0024] The guide rail 4 is externally equipped with a drive motor, which drives the sewing station 5 to slide on the guide rail. The sewing machine is fixed above the sewing station 5 by an adjustable bracket. The needle is vertically aligned with the center line of the mounting groove 2. The sliding stroke of the sewing station 5 covers the entire stitch length of the decorative ribbon. The start and stop signals of the sewing machine are triggered in real time by the PLC according to the position of the station.

[0025] Further as Figure 1 and Figure 2As shown, it is worth noting that the adjustment mechanism 3 includes two mounting brackets 301. The two mounting brackets 301 are fixedly connected to the top of the mounting plate 1 and are located on the front and rear sides of the mounting groove 2. A threaded rod 302 is rotatably installed in the front mounting bracket 301. A motor 303 is fixedly connected to the top of the threaded rod 302. The motor 303 is fixedly installed on the top of the mounting bracket 301. A guide rod 305 is fixedly connected in the rear mounting bracket 301. A hinge seat 304 is threadedly connected to the threaded rod 302. The hinge seat 304 slides within the front mounting bracket 301. Another hinge seat 304 is slidably arranged on the guide rod 305. The hinge seat 304 is connected to the limiting mechanism 6.

[0026] Among them, the motor 303 is linked with the sewing machine signal through the PLC controller. When the sewing program is started, the PLC synchronously controls the motor 303 to drive the threaded rod 302 to rotate, which drives the hinge seat 304 to rise and fall vertically, so that the height of the limit plate 605 matches the height of the conveyor belt, and can adjust the tension pressure of the conveyor belt to a certain extent, thereby improving its conveying stability.

[0027] In use, the motor 303 runs, causing the threaded rod 302 to rotate, which in turn drives the hinge seat 304 to slide within the mounting frame 301, thereby adjusting the height of the limiting plate 605 accordingly, so as to facilitate stable conveying of the decorative strip according to the conveying requirements.

[0028] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the limiting mechanism 6 includes a connecting shaft 601, which is rotatably mounted on the hinge seat 304. A connecting rod 602 is fixedly connected to the connecting shaft 601. An installation ring 603 is fixedly connected to the outside of the connecting rod 602. A movable rod 604 is slidably mounted inside the connecting rod 602. A limiting plate 605 is fixedly connected to one end of the movable rod 604. Two installation rings 603 are symmetrically arranged at the outer end of the connecting rod 602. The limiting plate 605 is located between the two installation rings 603 via the movable rod 604. The limiting plate 605 is an arc-shaped plate made of rubber. A first spring 606 is fixedly connected to one side of the movable rod 604 inside the connecting rod 602. A push block 607 is fixedly connected to the movable rod 604. The push block 607 passes through the connecting rod 602. Three connecting rods 602 are evenly distributed on the connecting shaft 601.

[0029] The mounting ring 603 has an annular guide groove on its inner edge (the groove width is slightly larger than the thickness of the trim). The trim passes through the guide groove between the two mounting rings 603. The arc-shaped surface of the limiting plate 605 fits against the outer surface of the trim. The preload of the first spring 606 provides radial clamping force to prevent the trim from shifting or warping during transport.

[0030] In use, the pressure on the limiting plate 605 causes the movable rod 604 to slide within the connecting rod 602 and compress the first spring 606. In turn, the elastic force of the first spring 606 improves the stability of the limiting plate 605 in conveying the trim.

[0031] As can be seen from the above working process, the adjustment mechanism 3, in conjunction with the limiting mechanism 6, enables convenient sewing and conveying of the decorative ribbon. This improves the efficiency of ribbon sewing when the ribbon is sewn at the sewing station 5. Furthermore, when the ribbon is sewn and conveyed in conjunction with the limiting mechanism 6, the stability of the ribbon during the conveying process is ensured, thus ensuring the efficiency of ribbon conveying.

[0032] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the clamping mechanism 7 includes two slide grooves 701. The two slide grooves 701 are symmetrically arranged on the left and right sides of the mounting groove 2 and are opened at the bottom of the guide rail 4. A C-shaped frame 702 is slidably arranged inside the slide groove 701. A clamping roller 703 is rotatably installed on one side of the C-shaped frame 702. A second spring 704 is fixedly installed on the outside of the C-shaped frame 702 inside the slide groove 701. Two second springs 704 are installed on the C-shaped frame 702 and are spaced apart.

[0033] In use, the clamping roller 703 is subjected to the elastic force of the second spring 704, which enables the clamping roller 703 to make close squeezing contact with the trim strip, thereby further improving the stability of the trim strip conveying through the limiting plate 605.

[0034] Specifically, when the trim strip passes through the clamping roller 703, the C-shaped frame 702 slides along the groove 701 and compresses the second spring 704, so that the clamping roller 703 always presses the edge of the trim strip with a constant pressure, eliminating conveying tension fluctuations.

[0035] This solution has the following working process: When this device is used, the decorative ribbon to be sewn is conveyed and positioned by the clamping roller 703 and the limiting plate 605. The ribbon is then conveyed through the clamping roller 703 and the limiting plate 605, and then through the clamping roller 703 on the other side. At this time, the guide rail 4 facilitates the operation of the sewing station 5. The ribbon is then sewn by the sewing machine. When the ribbon is conveyed through the limiting plate 605, it slides on the limiting plate 605. The limiting plate 605 drives the connecting shaft 601 to rotate on the hinge seat 304, completing the conveying of the ribbon. While the ribbon is being conveyed through the limiting plate 605, the motor 303 runs, causing the threaded rod 30... 2. Rotation causes the hinge seat 304 to slide within the mounting frame 301, thereby adjusting the height of the limiting plate 605 to facilitate stable conveying of the trim according to conveying requirements. During conveying, the pressure on the limiting plate 605 causes the movable rod 604 to slide within the connecting rod 602 and compress the first spring 606. The elastic force of the first spring 606 improves the stability of the limiting plate 605 in conveying the trim. Furthermore, the clamping roller 703 is subjected to the elastic force of the second spring 704, allowing it to make tight compression contact with the trim. This further enhances the stability of the trim conveying through the limiting plate 605.

[0036] In summary: the adjustment mechanism 3, in conjunction with the limiting mechanism 6, enables convenient sewing and conveying of the ribbon, thereby improving the efficiency of ribbon sewing at the sewing station 5. Furthermore, the limiting mechanism 6 ensures stable support for the ribbon during conveying, guaranteeing efficient ribbon conveying. The clamping mechanism 7, in conjunction with the limiting mechanism 6, further enhances the clamping effect on the ribbon during conveying, thereby improving the stability of ribbon conveying and facilitating stable sewing operations.
