After the lead screw 103 rotates, it can also drive the movable frame 104, which is equipped with the clamping assembly 3, to move laterally. The two lead screws 103 rotate synchronously through the pulley 105 and the synchronous belt 106. The connected lead screw 103 is driven to rotate through the motor 107.

[0032] In this embodiment: the quilting assembly 2 includes a U-shaped frame 201 fixedly installed on the frame 101, a linear guide rail 202 fixedly installed on one side of the U-shaped frame 201, a limit slide rail 203 fixedly installed above the U-shaped frame 201, an electric slide table 204 movably installed on the linear guide rail 202, a carrier frame 205 fixedly connected to one side of the electric slide table 204, a hydraulic rod 206 fixedly installed inside the carrier frame 205, a lifting frame 207 is provided between the telescopic end of the hydraulic rod 206 and the carrier frame 205, and a quilting machine head 208 is fixedly installed below the lifting frame 207;

[0034] The linear guide rail 202, the limiting slide rail 203 and other components are installed at a position higher than the clamping assembly 3 through the U-shaped frame 201, the movable range of the electric sliding table 204 is limited by the linear guide rail 202 and the limiting slide rail 203, so that the electric sliding table 204 can stably drive the carrier 205 and other components to move longitudinally in the quilting and sewing machine, the height of the lifting frame 207 whose movable range is limited by the carrier 205 is adjusted through the hydraulic rod 206, the quilting and sewing machine head 208 is installed through the lifting frame 207, so that the quilting and sewing machine head 208 can move longitudinally with the electric sliding table 204, and the hydraulic rod 206 can adjust the height of the quilting and sewing machine head 208 as needed during the quilting and sewing interval, and the quilting and sewing machine head 208 after contacting the backpack performs quilting and sewing on the backpack.

[0035] In the embodiment, the clamping assembly 3 includes a pre-tightening component that can transversely tension the part of the backpack to be quilted and sewn, a fixing component that can longitudinally tension the part of the backpack to be quilted and sewn and avoid jumping during quilting and sewing, and a connecting component that can conveniently fix the placed backpack. The fixing component includes an L-shaped frame 301 fixedly installed on the moving frame 104, a cylinder 302 fixedly installed on one side of the L-shaped frame 301, a vertical rod 303 movably connected to the L-shaped frame 301, a pressing handle 304 arranged between the vertical rod 303 and the telescopic end of the cylinder 302, a pressing strip 305 fixedly connected to the front and rear of the pressing handle 304, a telescopic rod 306 fixedly connected to the front and rear of the L-shaped frame 301, a first supporting rod 307 fixedly connected between the telescopic rods 306 at the same longitudinal position, a gap 308 arranged on the L-shaped frame 301 and the first supporting rod 307, the pre-tightening component includes a baffle 309 fixedly connected to one side of the L-shaped frame 301, a first supporting rod 310 movably connected between the L-shaped frame 301 and the baffle 309, a spring 311 arranged on one side of the first supporting rod 310, a second supporting rod 312 movably connected to one side of the first supporting rod 307, a second supporting rod 313 arranged between the first supporting rod 310 and the second supporting rod 312, and an inner threaded cylinder 314 movably connected to the vertical rod 303 and the first supporting rod 307, respectively, a screw rod 315 fixedly connected between adjacent inner threaded cylinders 314, and a rotating handle 316 movably connected to the screw rod 315.

[0036] The L-shaped frame 301 is slidably connected to the vertical rod 303, the L-shaped frame 301 and the baffle 309 are slidably connected to the first supporting rod 310, the first supporting rod 307 and the second supporting rod 313 are slidably connected to the second supporting rod 312, the vertical rod 303 and the first supporting rod 307 are rotatably connected to the inner threaded cylinder 314 connected thereto, the inner threaded cylinder 314 is threadedly connected to the screw rod 315, and the screw rod 315 is slidably connected to the rotating handle 316.

[0037] The L-shaped frame 301 is used to install the cylinder 302, the vertical rod 303, the telescopic rod 306, the baffle 309 and other components. The vertical rod 303 is used to make the pressing handle 304, which is installed with the pressing strip 305, stably ascend and descend under the action of the cylinder 302. The telescopic rod 306 is used to make the first supporting rod 307 only move longitudinally relative to the L-shaped frame 301. The gap 308 is used to accommodate the side piece of the backpack provided with a zipper, so as to prevent the side piece and the front and rear main materials of the backpack from being stacked together. The baffle 309 and the spring 311 are used to jointly limit the movable range of the first supporting rod 310, so that the first supporting rod 310 has a tendency to move away from the L-shaped frame 301 when not subjected to external force, but will not be separated from the L-shaped frame 301. The second supporting rod 312 is used to cooperate with the first supporting rod 310 to install the second supporting rod 313. The second supporting rod 313 is used to contact and abut against the bottom of the bag. The inner threaded cylinder 314 and the screw rod 315 are used to connect the vertical rod 303 and the first supporting rod 307, so as to synchronously transmit the height change of the vertical rod 303 to the first supporting rod 307, and make the first supporting rod 307 be able to move longitudinally relative to the L-shaped frame 301. The knob 316 is used to conveniently rotate the screw rod 315, so that the distance between the two inner threaded cylinders 314 connected with the screw rod 315 can be changed, and then the initial distance between the first supporting rod 307 and the vertical rod 303 is changed.

[0038] Working principle: when the quilting machine is installed for processing the backpack, appropriate lengths of the first supporting rod 310 and the second supporting rod 312 should be selected, and the distance from the second supporting rod 313 to the gap 308 should be greater than the height of the backpack. Before fixing the backpack, according to the width of the front and rear main materials of the backpack, the screw rod 315 is rotated by the knob 316, so that the distance between the two groups of first supporting rods 307 is slightly smaller than the width of the main materials. Then the backpack is set into the clamping assembly 3 from the position of the second supporting rod 313 in a manner that the bag opening faces the cylinder 302 and the part to be quilted is on the top, so that the part to be quilted covers the L-shaped frame 301 and the first supporting rod 307, and the side piece away from the bottom of the bag falls into the gap 308. In this process, the spring 311 is compressed, so that the second supporting rod 313 can transversely tension the main materials of the backpack.

[0039] After the backpack is set, the cylinder 302 can work, so that the pressing strip 305 moves downward and presses the main materials of the backpack. In this process, the first supporting rod 307 moves away from the L-shaped frame 301 under the action of the connecting piece composed of the inner threaded cylinder 314 and other components, so as to realize the longitudinal tension of the main materials of the backpack by the first supporting rod 307 and the compression of the main materials of the backpack by the pressing strip 305, thereby completing the full tension and fixation of the part to be quilted of the backpack.

[0040] After the bag is fixed, the motor 107 is operated to move the moving frame 104, the clamping assembly 3 and the bag fixed in the clamping assembly 3 to the quilting machine head 208, and after being moved to the position, the motor 107, the electric sliding table 204 and the hydraulic rod 206 are cooperated to move the bag and the quilting machine head 208 relative to each other as needed, so that the quilting machine head 208 fully contacts the part to be quilted of the bag and quilts the required lines or patterns.

[0041] The preferred embodiments of the utility model are described in detail in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the technical personnel in the technical field without departing from the purpose of the utility model.
