DETAILED DESCRIPTION

[0047] The following is combined with Figure 1-6 This application is described in further detail.

[0048] The embodiments of the present application disclose a seamless collar structure and a production process thereof, and clothing.

[0049] Reference Figure 1 The seamless collar structure comprises a collar lining 1, a collar surface 2 and a composite film 4 connected between the collar lining 1 and the collar surface 2. The collar lining 1 and the collar surface 2 are knitted fabrics, and the collar lining 1 and the collar surface 2 are formed with a folding line 3 along a symmetrical midline for turning up the collar.

[0050] In the embodiment of the present application, the composite film 4 includes a lining 42 and hot melt adhesive layers 41 disposed on opposite sides of the lining 42. The hot melt adhesive layers 41 are high-elastic hot melt adhesive films, and the two hot melt adhesive layers 41 are bonded at the folding line 3. The lining 42 is a high-elastic soft lining. The lining 42 is divided into two halves along the folding line 3, and there is a gap between the two parts. Therefore, the thickness of the composite film 4 at the folding line 3 is less than that at other places, and it is easy to form a crease when stressed, making the collar easy to fold. It should be noted that when manufacturing the composite film 4, it can be preheated so that the lining 42 and the hot melt adhesive layer 41 are connected, and the middle parts of the hot melt adhesive layers 41 are bonded to facilitate subsequent placement between the collar lining 1 and the collar face 2.

[0051] In other embodiments, the composite film 4 includes composite layers on both sides and a thin adhesive layer in the middle. The composite layer is a composite structure of a middle lining 42 and hot melt adhesive layers 41 on both sides, and the thin adhesive layer is a hot melt adhesive strip. The effects of the two embodiments are similar, and the difference is that the structure of the composite film 4 disclosed in the embodiment of the present application is more convenient for production and processing.

[0052] The embodiment of the present application discloses a piece of clothing, including the seamless collar structure described above. Specifically, the type of clothing can be a shirt, a POLO shirt or other collared clothing.

[0053] Refer to Figure 2 , a production process of a seamless collar structure, including the following steps:

[0054] Cutting: Cut high-elastic knitted fabric to obtain a collar lining cut piece and a collar face cut piece;

[0055] Pre-sewing: Align the collar lining cut piece and the collar face cut piece, and sew them together at both ends with a flatbed sewing machine to obtain a pre-sewn piece 5;

[0056] Laminating: Place the composite film 4 between the collar lining cut piece and the collar face cut piece through a laminating device 7, and then heat it to melt the hot melt adhesive layer 41 and bond them to each other to obtain a laminated collar;

[0057] Trimming: Cut and trim the edges of the laminated collar to remove the stitches;

[0058] Shaping: Fold the laminated collar to form a folding line 3, and press and iron it to shape to obtain a finished collar 6.

[0059] Refer to Figure 3The composite device 7 includes a base 71, a die base 72 disposed on the base 71, a feeding assembly 73, a pressing assembly 74 and a discharging assembly 75. The die base 72 is connected to a flaring sleeve 76 on one side facing the discharging assembly 75. The pre-seam sheet 5 is firstly put on the outside of the flaring sleeve 76, and then the composite film 4 is put into the flaring sleeve 76 by using the feeding assembly 73, and then the pressing assembly 74 is started to press the pre-seam sheet 5 and the composite film 4, and finally the discharging assembly 75 is started to move the pressed pre-seam sheet 5 and the composite film 4 out of the flaring sleeve 76, so that the composite of the pre-seam sheet 5 and the composite film 4 can be semi-automatically completed, with low error rate and high efficiency.

[0060] Reference Figure 3 , Figure 4 The die base 72 is fixedly connected to the upper side of the base 71 by bolts, and the corresponding die base 72 can be replaced according to the size requirements of different collars. The die base 72 is formed with an arc surface 721 on one side facing the feeding assembly 73, and the arc of the cross section of the arc surface 721 is the same as the arc of the side of the pre-seam piece 5, so as to facilitate the accurate positioning of the pre-seam piece 5.

[0061] A flaring sleeve 76 is fixedly connected to the arc surface 721 in the middle of the die base 72. The flaring sleeve 76 includes two thin plates arranged along a horizontal plane and parallel to each other, and an arc plate integrally connected between the corresponding ends of the thin plates. The lateral length of the flaring sleeve 76 is equal to the distance between the stitches at the two ends of the cut piece, and the vertical inner width of the flaring sleeve 76 is greater than the thickness of the composite film 4. Since the collar lining and collar surface pieces are both made of elastic fabrics, they can be expanded and sleeved on the outside of the flaring sleeve 76 to facilitate the placement of the composite film 4 into the pre-seam piece 5. A plurality of blanking notches 761 are arranged at intervals on the side of the flaring sleeve 76 away from the die base 72. In the embodiment of the present application, five blanking notches 761 are arranged, and in other embodiments, three, four or more blanking notches can also be arranged, depending on actual needs.

[0062] Reference Figure 5 The blanking assembly 75 includes a blanking frame 751 for fixing the clamping assembly 74, a blanking screw rod 752 threadedly connected to the lower end of the blanking frame 751, a guide rod 753 slidably connected to the lower end of the blanking frame 751, and a blanking motor 754 for driving the blanking screw rod 752 to rotate. The blanking frame 751 is frame-shaped and sleeved on the outside of the flaring sleeve 76. The blanking screw rod 752 and the guide rod 753 are parallel and perpendicular to the die base 72. Both ends of the blanking screw rod 752 are rotatably connected to a rotating seat 755, and the rotating seat 755 is fixedly connected to the base 71. Both ends of the guide rod 753 are fixedly connected to a guide seat 756, and the guide seat 756 is fixedly connected to the base 71. The blanking motor 754 is a servo motor, and the body is fixedly connected to the base 71, and the output shaft is fixedly connected to the blanking screw rod 752. The unloading motor 754 is started to drive the unloading screw rod 752 to rotate, thereby driving the unloading frame 751 to move closer to or away from the mold base 72.

[0063] Reference Figure 4 , Figure 5 In order to facilitate the removal of the aligned pre-seam sheet 5 and the composite film 4 from the flaring sleeve 76, two clamping assemblies 74 are provided and are respectively located at the upper and lower sides of the flaring sleeve 76. The clamping assembly 74 includes a clamping strip 741 for extending into the blanking notch 761 and a clamping cylinder 742 for driving the clamping strip 741 to move. The cylinder body of the clamping cylinder 742 is fixedly connected to the blanking frame 751, and the piston rod is arranged toward the flaring sleeve 76 and is fixedly connected to the clamping strip 741. The clamping strip 741 includes a connecting strip fixedly connected to the piston rod of the clamping cylinder 742, and a plurality of clamping rods fixedly connected to the side of the connecting strip close to the flaring sleeve 76 at intervals. There are five clamping rods and they correspond to the positions of the blanking notch 761 one by one. The clamping rod is made of rubber, has elasticity and large friction, and has a good clamping effect. Both ends of the connecting strip are slidably penetrated with sliding rods fixedly connected to the blanking frame 751, which play a guiding role in the sliding of the clamping strip 741. One end of the slide rod close to the flaring sleeve 76 is connected to a limiting disk, which limits the movement of the pressing strip 741 and ensures the pressing effect.

[0064] Reference Figure 3 , Figure 6 The feeding assembly 73 includes a support plate 731 for placing the composite film 4 and a feeding cylinder 732 for pushing the support plate 731 into the expansion sleeve 76. The cylinder body of the feeding cylinder 732 is fixedly connected to the base 71 through a support seat, and the piston rod is arranged toward the expansion sleeve 76 and fixedly connected to the support plate 731. The side of the support plate 731 close to the expansion sleeve 76 is arc-shaped and matched with the arc surface 721, and the upper end of the support plate 731 is for placing the composite film 4. A clearance notch 7311 corresponding to the blanking notch 761 is provided on the side of the support plate 731 facing the expansion sleeve 76. When the support plate 731 is inserted into the expansion sleeve 76 to fit the arc surface 721, the clearance notch 7311 can be inserted into the pressing strip 741. A convex strip 7312 with a semicircular cross-section is fixedly connected to the middle of the upper side of the support plate 731. When the composite film 4 is placed on the upper side of the support plate 731, the convex strip 7312 is stuck in the center line of the composite film 4, that is, the fold line 3, thereby ensuring that the position of the composite film 4 relative to the support plate 731 is fixed.

[0065] The implementation principle of the composite device of the embodiment of the present application is:

[0066] First, expand the pre-sewn piece 5 and put it on the outside of the flaring sleeve 76, then push the pre-sewn piece 5 until it abuts against the arc surface 721. Next, place the composite film 4 on the pallet 731, start the feeding cylinder 732, and put the composite film 4 into the flaring sleeve 76. Then start the pressing cylinder 742, and the two pressing strips 741 move towards each other to press the pre-sewn piece 5 and the composite film 4. Next, the feeding cylinder 732 resets, and the pallet 731 moves out of the flaring sleeve 76, while the composite film 4 is pressed and cannot move out. Finally, start the discharging motor 754, the discharging lead screw 752 rotates to drive the discharging frame 751 to move away from the die base 72, thereby moving the pressed pre-sewn piece 5 and composite film 4 out of the flaring sleeve 76. After the pressing cylinder 742 resets, the pre-sewn piece 5 and the composite film 4 that are combined can be obtained, which is convenient for subsequent processing.

[0067] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
