[0033] like Figure 2 and Figure 3 As shown, the feeding mechanism 40 is based on the full-automatic feeding under the hat brim reversing sewing processing mode, and the operation is stable and reliable. Specifically:

[0034] The unloading mechanism 40 includes a frame 41 and an unloading robot disposed on the frame 41 .

[0035] The frame 41 is provided with a feeding motor 42, a first guide rail 43 and a first slider 44; the first guide rail 43 is horizontally extended to the left and right and is arranged at the front side of the frame 41; the first slider 44 is adapted to the first guide rail 43 and can slide left and right along the first guide rail 43.

The upper end of the first suction arm 46 is connected to the outer end of the piston rod of the first cylinder 47, and the cylinder body of the first cylinder 47 is hinged to the lower end of the first connecting arm 48. In this embodiment, an L-shaped connecting plate 471 is provided on the cylinder body of the first cylinder 47, and the L-shaped connecting plate 471 includes a horizontal plate portion and a vertical plate portion extending upward from the front end of the horizontal plate portion, the horizontal plate portion is connected to the cylinder body of the first cylinder 47, and the lower end of the first connecting arm 48 is hinged to the vertical plate portion. Further, the translation drive unit is connected to the unloading motor 42, so that: the translation drive unit drives the unloading motor 42, the first slider 44 and the unloading manipulator to translate left and right together.

[0037] The unloading motor 42 is mounted on the sliding seat 421, the piston rod of the second cylinder 45 is connected to the sliding seat 421, the rear side of the frame 41 is provided with a second guide rail 412, the second guide rail 412 is horizontally extended left and right, the sliding seat 421 is adapted to the second guide rail 412, and the second cylinder 45 drives the sliding seat 421 to slide left and right along the second guide rail 412. The driving end of the unloading motor 42 passes forward through the strip-shaped through slot 411, and when the translation drive unit drives the unloading motor 42 to translate left and right, the driving end of the unloading motor 42 translates left and right in the strip-shaped through slot 411 accordingly.

[0038] Therefore, by ingeniously designing the structure of the unloading manipulator, the first cylinder 47 drives the first suction arm 46 to move forward and backward relative to the first connecting arm 48. At the same time, the upper end of the first connecting arm 48 is hinged to the outer end of the first swing rod 49, and the inner end of the first swing rod 49 is connected to the driving end of the unloading motor 42, so that the unloading motor 42 drives the first swing rod 49 to rotate around the front and rear axis. In this way, when unloading is required, the first suction arm 46 sucks the brim and the first cylinder 47 drives the first suction arm 46 to move forward relative to the first connecting arm 48, so that the brim avoids the area below the sewing needle of the sewing machine head 10, and then the unloading motor 42 drives the first swing rod 49, thereby realizing full-automatic unloading in the brim reversing sewing processing mode, and the operation is stable and reliable. In addition, the brim sewing unloading mechanism 40 of the utility model is set in the brim sewing equipment, so that the structure of the brim sewing equipment is compact and space-saving.

In this embodiment, the first guide rail 43 extends left and right to the area where the automatic feeding mechanism 30 is located. In this way, by setting the second slider 35 adapted to the first guide rail 43 and being able to slide left and right along the first guide rail 43, the second connecting arm 33 can be movably arranged up and down along the second slider 35, which is equivalent to using the second slider 35 to constrain the second connecting arm 33 to move left and right and move up and down in multiple directions. The automatic loading mechanism 30 and the automatic unloading mechanism 40 are designed as an integrated mechanism, which has a compact structure, saves space, and occupies little space in the left and right directions on the machine. At the same time, each of them is equipped with a motor as a power control, and cooperates with guide rails and rocker arms to achieve better controllability of loading and unloading.

[0040] Next, the automatic processing process of the hat brim sewing equipment is introduced as follows:

[0041] The automatic feeding mechanism 30 delivers the brim 70 to the feeding area, and the material shifting module 50 moves forward to the feeding area and presses down to hold the brim first (because the front arc edge of the curved brim is toward the rear end of the cylinder 20, and the inner arc edge reserved at the rear end is toward the front end of the cylinder 20, therefore, the material shifting module 50 can better hold and position the curved brim (for example, the part where the inner arc edge is located)), and the material shifting module 50 pushes the brim from the feeding area to the sewing area below the sewing machine head 10 (the front arc edge of the curved brim is a harder and more regular part, and the positioning control is better when it is pushed toward the front end); then, the clamping assembly 60 at the periphery of the sewing area presses and positions the front arc edge of the curved brim; then, the material shifting module 50 releases the pressure on the curved brim and resets forward to the front of the feeding area; then, as the cylinder 20 rotates, The sewing machine head 10 sews along the front arc edge of the curved brim, and at the same time, the automatic loading mechanism 30 sends the next brim to the loading area, and the material shifting module 50 moves forward and presses down to hold the brim, that is, it is in a waiting state; after sewing is completed, the unloading motor 42 works to make the first suction arm 46 move downward until it is sucked onto the brim, and the clamping assembly 60 at the periphery of the sewing area releases the curved brim, and then, the first cylinder 47 drives the first suction arm 46 to move forward relative to the lower end of the first connecting arm 48, so that the brim avoids the area below the sewing needle of the sewing machine head 10, and then, the translation drive unit and the unloading motor 42 work simultaneously, so that the first suction arm 46 deviates from the left upward trajectory, sends the brim to the top of the material receiving bin, and releases the brim to fall into the material receiving bin.

[0042] The design focus of the utility model is that it mainly realizes the fully automatic and precise shifting of the brim on the cylinder in the brim reversing sewing processing mode by ingeniously designing the structure of the material transfer module. The operation is stable and reliable, and the brim is accurately sent to the sewing area, which is beneficial to improving the sewing processing quality. Moreover, the structure is compact through the built-in setting of the multi-stage front and rear translation drive unit and the lifting drive unit.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
