Description

Technical Field

[0001] The utility model relates to the technical field of buttoning, in particular to a buttoning machine for backpack production. Background Art

[0002] The button fastening machine is suitable for fastening various metal snap buttons, craft buttons, jeans buttons, etc. on all kinds of clothing, shoes, hats and leather. It has the advantages of simple structure, single action and easy operation. It is widely used in clothing factories and leather bag processing enterprises.

[0003] After searching, the Chinese patent publication number is CN221153132U, which discloses an automatic buttoning machine for the production of polyester backpacks. This patent achieves the function of auxiliary fixation by making the ball bearing fit the surface of the cloth, and aligns the position where the button is to be made with the positioning hole for buttoning. However, this device has certain problems: the contact area between the ball bearing and the cloth is small, which plays an auxiliary limiting role. If the cloth itself has slight wrinkles, the ball bearing alone cannot flatten them, affecting the position and shape of the button. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1-Figure 5As shown, a buckle-fastening machine for backpack production includes a workbench 101, a bracket 102 is fixedly connected to one side of the top of the workbench 101, a lifting plate 203 is slidably connected to the bracket 102, a buckle-fastening head 302 is provided on the side of the lifting plate 203 away from the bracket 102, and a front-to-back symmetrical fixing frame 103 is fixedly connected to the top of the workbench 101. The fixing frame 103 is provided with a flattening mechanism, which includes a sliding rod 401. The sliding rod 401 is slidably connected to the fixing frame 103 near the buckle-fastening mechanism. On one side of the head 302, the bottom of the sliding rod 401 is fixedly connected to a connecting plate 402, and the side of the connecting plate 402 away from the buckle head 302 is fixedly connected to a connecting spring 403, and the top of the connecting spring 403 is fixedly connected to the fixing frame 103. The bottom of the connecting plate 402 is hinged to a movable plate 404 on the side close to the buckle head 302, and the movable plate 404 is rotatably connected to an auxiliary roller 405 at one end of the hinge axis away from the connecting plate 402. In the initial state, the movable plate 404 rotates around the hinge of the connecting plate 402. The side of the connecting shaft away from the buckle head 302 is tilted at a certain angle, and the side of the movable plate 404 away from the buckle head 302 is fixedly connected with a return spring 406, and the return spring 406 is fixedly connected to the connecting plate 402. When the lifting plate 203 abuts and squeezes the top of the symmetrical sliding rod 401, the sliding rod 401 drives the connecting plate 402 to move downward, causing the connecting spring 403 to deform, and the connecting plate 402 drives the movable plate 404 to descend until the auxiliary roller 405 contacts the cloth and rolls. As the connecting plate 402 descends, the movable plate 404 drives the auxiliary roller 405 to tilt around the hinge axis of the connecting plate 402 away from the buckle head 302, and the angle between the movable plate 404 and the connecting plate 402 becomes smaller, causing the return spring 406 to be compressed and deformed. The front and rear symmetrical auxiliary rollers 405 both roll to the side away from the buckle head 302, flattening the position where the buckle is required, ensuring the accuracy of the position and shape during subsequent buckling, and avoiding displacement of the fabric around the buckle due to the buckle pressure.

[0026] The lifting plate 203 descends and squeezes the sliding rod 401, causing the connecting spring 403 to deform, so that the connecting plate 402 drives the auxiliary roller 405 to descend to contact the cloth and roll, driving the movable plate 404 to rotate around the hinge axis of the connecting plate 402, causing the return spring 406 to deform, and flattening the cloth to be buttoned.

[0027] A lifting screw rod 201 is rotatably connected inside the bracket 102, and a power motor 202 is fixedly connected to the top of the bracket 102. The output shaft of the power motor 202 is fixedly connected to the lifting screw rod 201, and the lifting plate 203 is threadedly connected to the lifting screw rod 201. The power motor 202 drives the lifting screw rod 201 to rotate, so that the lifting screw rod 201 drives the lifting plate 203 to move downward.

[0028] The side of the lifting plate 203 away from the power motor 202 is fixedly connected to the cylinder 301, and the buckle head 302 is fixedly connected to the output shaft of the cylinder 301. A positioning hole is provided on the top of the workbench 101, and the buckle head 302 is coaxial with the positioning hole. The cylinder 301 drives the buckle head 302 to descend, and the buckle head 302 is pressed down to align with the positioning hole to buckle the cloth.

[0029] Symmetrical mounting frames are fixedly connected to both the front and rear ends of the workbench 101 . The side of the symmetrical mounting frame close to the workbench 101 is rotatably connected to the active roller 501 , and the side of the mounting frame away from the workbench 101 is rotatably connected to the driven roller 502 .

[0030] One end of the active roller 501 in front of the workbench 101 is connected to a belt 503, and the belt 503 is connected to the active roller 501 at the rear. A conveying motor 6 is fixedly connected to the side of the rear mounting frame away from the belt 503, and the output shaft of the conveying motor 6 is fixedly connected to the active roller 501 at the rear, so that the cloth passes from bottom to top between the active roller 501 and the driven roller 502 at the rear, and then the movable end of the cloth passes under the front and rear symmetrical auxiliary rollers 405, and passes from top to bottom between the active roller 501 and the driven roller 502 at the front, and then the conveying motor 6 drives the front and rear symmetrical active rollers 501 to rotate synchronously through the belt 503, so that the cloth passes through the positioning hole at a uniform speed from back to front under the squeezing of the active roller 501 and the driven roller 502.

[0031] A collecting box 7 is slidably connected to one side of the workbench 101 away from the bracket 102. The metal buckles needed for buckling are collected and stored in the collecting box 7 for easy removal when used.

[0032] Working principle: When in use, the cloth passes from bottom to top between the active roller 501 and the driven roller 502 at the rear, and then the movable end of the cloth passes under the front and rear symmetrical auxiliary rollers 405, and passes from top to bottom between the front active roller 501 and the driven roller 502, and then the conveying motor 6 drives the front and rear symmetrical active rollers 501 to rotate synchronously through the belt 503, so that the cloth passes through the positioning hole from back to front at a uniform speed under the squeezing of the active roller 501 and the driven roller 502, and then the power motor 202 drives the lifting screw 201 to rotate, so that the lifting screw 201 drives the lifting plate 203 to move downward, when the lifting plate 203 abuts and squeezes the top of the symmetrical sliding rod 401, the sliding rod 401 drives the connecting plate 402 to move downward, causing the connecting spring 403 to deform, and the connecting plate 402 with The movable plate 404 is moved down until the auxiliary roller 405 contacts the fabric and rolls. As the connecting plate 402 descends, the movable plate 404 drives the auxiliary roller 405 to tilt around the hinge axis of the connecting plate 402 away from the buckling head 302. The angle between the movable plate 404 and the connecting plate 402 becomes smaller, causing the return spring 406 to be compressed and deformed. The front and rear symmetrical auxiliary rollers 405 all roll to the side away from the buckling head 302, flattening the position where the buckle is required, ensuring the accuracy of the position and shape during subsequent buckling, and avoiding displacement of the fabric around the buckle due to the buckling pressure. Then the cylinder 301 drives the buckle head 302 to descend, and the buckle head 302 is pressed down to align with the positioning hole to buckle the cloth. The metal buckles required for buckling are collected and stored in the collection box 7 for easy removal when used.
