Description

Technical Field

[0001] The utility model relates to the technical field of garment production, in particular to a snap button fastening device. Background Art

[0002] Snap buttons, also known as male and female buttons, push buttons, snap fasteners, etc., are a type of button. This kind of button consists of two parts. One part is called the male button, with a dot protruding in the middle; the other part is called the female button, with a concave hole in the middle. After the dot on the male button is pressed into the hole of the female button, it will be clamped by two parallel springs on the side of the female button, thus generating an opening and closing force for fixing clothes. When installing snap buttons, according to the corresponding relationship between the male and female buttons, their respective button fastening molds are used to ensure that the snap buttons are pressed and fastened on the finished garment one by one.

[0003] However, due to the different shapes and structures of snap buttons, different button fastening molds are required when installing the snap buttons. The existing button pressing production line needs to use two machines to press the male and female snap buttons respectively, resulting in low production efficiency. Summary of the Utility Model

[0023] The following further details the specific embodiments of the utility model with reference to the accompanying drawings.

[0024] As shown in Figure 1-2 , a mother-and-son button fastening device of the utility model includes a workbench 1, a frame 2, a cylinder 3, a turntable 4, a protective frame 5, and a sensing member 6;

[0025] The workbench 1 is provided with two feeding grooves 11 for partitioned feeding of the mother-and-son buttons, facilitating the taking of the male buttons and female buttons.

[0026] The frame 2 is located on the workbench 1, and the cylinder 3 is fixed to the top of the frame 2;

[0027] The turntable 4 includes a rotating rod 41, an upper table 42, a lower table 43, and a reset member 45. A rotating shaft 21 is provided at the bottom of the frame 2, and the rotating rod 41 is connected to the rotating shaft 21; a number of first through holes 421 are provided on the upper table 42, and a buttoning die 44 is connected in the first through hole 421 through the reset member 45;

[0028] As Figure 4 shown, the reset member 45 includes a top plate 451, a spring 452, and a driven rod 453. The top plate 451 is coaxially connected to the first through hole 421 through the spring 452, and the buttoning die 44 is connected to the bottom end of the driven rod 453. The piston rod 31 of the cylinder 3 at the top presses downward into the first through hole 421 and presses down the top plate 451, so that the driven rod 453 squeezes the spring 452 and drives the buttoning die 44 to press down; when the piston rod 31 rises and removes the force on the top plate 451, the spring 452 drives the driven rod 453 to reset.

[0029] Preferably, the buttoning die 44 is threadedly connected to the driven rod 453, which is convenient for disassembling and assembling the buttoning die 44. It can not only replace the buttoning die 44 according to the buttoning requirements, but also adjust the initial distance between the buttoning die 44 and the lower table 43 by screwing according to the operation needs.

[0030] A rubber head 46 is provided at the bottom end of the buttoning die 44. In order to ensure the pressing force, the general buttoning die 44 is made of rigid metal material. The rubber head 46 contacts the surface of the button, which can avoid damaging the button.

[0031] A number of second through holes 431 are provided on the lower table 43, and a button pressing seat 47 is connected to the second through hole 431. As Figure 5 shown, the button pressing seat 47 includes a connecting rod 471 and a limiting ring 473. The limiting ring 473 is connected to the top of the lower table 43 through the connecting rod 471. The connecting rod 471 is provided with a connecting induction channel 474, and the limiting ring 473 is provided with a feeding table 472;

[0032] The male and female buttons are respectively placed in the corresponding limiting rings 473. The feeding table 472 plays a role in supporting the material, and the limiting ring 473 plays a role in limiting the button, ensuring that the end of the upper buttoning die 44 falls within the limiting ring 473. The connecting rod 471 is threadedly connected to the second through hole 431. According to the buttoning requirements and the size of the button, by screwing the connecting rod 471, the replacement of the button pressing seat 47 can be quickly completed.

[0033] The protective frame 5 is connected to one side of the frame 2. As Figure 3As shown in the figure, the protective frame 5 includes a fixing rod 51 and a protective ring 52, and the protective ring 52 is located at the end of the fixing rod 51; the fixing rod 51 is preferably a flexible fixing rod. During the button nailing process, the fixing rod 51 is bent under the button nailing die 44, and the button nailing die 44 passes through the protective ring 52. The protective ring 52 plays a protective role to prevent the operator's hand from being crushed due to improper operation. When it is necessary to rotate the upper table 42 and the lower table 43, the protective frame 5 can be bent away first to avoid interfering with the rotation of the turntable 4.

[0034] The sensing member 6 is coaxially arranged with the piston rod 31 of the cylinder 3 and is located below the lower table 43. The sensing member 6 can be an existing distance measuring sensor. After the turntable 4 rotates, the target button nailing seat 47 is directly above the sensing member 6. The sensing member 6 measures the distance through the connection induction channel 474 to ensure that the target button nailing die 44 rotates to be coaxial with the piston rod 31, avoiding the dislocation of the piston rod 31 and the first through hole 421.

[0035] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
