Description

Technical Field

[0001] The utility model relates to the technical field of button punching machines, in particular to a swing arm type lower slide block group of a hole punching and button punching machine. Background Art

[0002] Buttons are accessories used to connect two pieces of fabric on clothing. In the clothing manufacturing process, buttons need to be nailed to the fabric using a button-pressing machine. Such buttons generally include upper and lower buttons (or male and female buttons). The pieces of fabric to be connected are placed between the upper and lower buttons, and then the button-pressing machine (button-pressing machine) is used for punching to combine the upper and lower buttons together to complete the installation with the fabric. At present, in order to reduce labor and improve processing efficiency, automatic button-pressing machines have been used to realize automatic button feeding of upper and lower buttons.

[0003] In the traditional button punching machine, the punching die base is connected to the punching die base cylinder, which drives the punching die base to move parallel to one side of the lower die to punch holes and position buttons. After the punching is completed, the punching die base cylinder drives the punching die base to leave the lower die to facilitate the riveting operation. In this structure, the punching die base cylinder and the push cylinder are installed on the same base, and the two are very close. This structure causes interference between the actions and low operating accuracy, so improvements need to be made to these problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 to Figure 4 As shown, the utility model provides a technical solution: a swing arm type lower slider group of a punching and button punching machine, comprising a base 1, a nail slot assembly 2 for feeding from right to left is arranged on one side of the base 1, a button outlet plate 3 fixedly connected to the base 1 is arranged at the outlet end of the nail slot assembly 2, a button blocking mechanism is arranged at one end of the nail slot assembly 2, and the button blocking mechanism comprises a button blocking sheet seat 21, and a button blocking spring sheet 22 is connected to the button blocking sheet seat 21 on one side through a torsion spring, when the button comes out from the outlet end of the nail slot assembly 2, it is blocked and stopped by the button blocking spring sheet 22, and then the material pushing assembly 4 comes over to push the material;

[0024] A pushing assembly 4 for pushing material from back to front is arranged on the base 1, a lower mold 10 which can move up and down is arranged at the front end of the button plate 3, the lower end of the lower mold 10 is connected to the lower mold buffer rod 11, the lower mold buffer rod 11 is provided with two buffer springs, the two buffer springs are respectively a buffer spring 12 and a clamping spring 13, the buffer spring 12 makes the lower mold buffer rod 11 have a certain buffer elastic force, so that the lower mold has a certain elastic micro-motion ability, and is matched with fabrics of different thicknesses. A clamping spring 13 is arranged on the outer side of the lower mold buffer rod 11, one end of the clamping spring 13 presses on the base 1, and the other end presses on the lower end of the lower mold buffer rod 11, so that the roller 1101 at the lower end of the lower mold buffer rod 11 always keeps elastic pressure on the surface of the lower mold lifting slider to avoid separation.

[0025] See also Figure 2 and Figure 3 A rotatable punching die base 5 is connected to the button plate 3 through a pin structure. A knife edge 501 is provided on the punching die base 5. The knife edge 502 is used to cooperate with the punching knife above to punch holes in the cloth.

[0026] One side of the bottom of the punching die base 5 is connected with a movable punching die base swing rod 1 6 through a pin shaft structure, and one side of the punching die base swing rod 1 6 is threadedly connected with a limiting bolt 14, and the bottom of the punching die base swing rod 1 6 is connected with a punching die base swing rod 2 7 through a pin shaft structure, and one side of the punching die base swing rod 2 7 is connected with a punching die base swing rod cylinder 15 for driving the punching die base swing rod 2 7 to move, and the bottom of the punching die base swing rod 2 7 is rotatably mounted on the lower base 8 through a pin shaft structure, and a lower die lifting slider 9 is slidably connected to one side of the lower base 8, and the punching die base swing rod cylinder 15 can drive the two punching die base swing rods to swing, and the swinging of the two punching die base swing rods can drive the punching die base 5 to swing, so that the punching die base 5 can flexibly switch positions. When it is necessary to cooperate with punching and positioning buttons, the punching die base 5 swings to the top of the lower die 10, and when the upper and lower dies need to be relatively stamped to rivet the male and female buttons, the punching die base 5 flexibly swings to avoid.

[0027] Please pay attention to Figure 4 The lower base 8 is fixed, and a rotatable roller 1101 is arranged at the bottom of the lower mold buffer rod 11. The roller 1101 abuts against the surface of the lower mold lifting slider 9. One end of the lower mold lifting slider 9 is connected to a slider cylinder 91. When the slider cylinder 91 drives the lower mold lifting slider 9 to move forward and backward, the lower mold buffer rod 11, the lower mold 10 and the button can be driven to rise and fall together, so as to drive the upper and lower molds to relatively stamp so that the male and female buttons are riveted at the small hole position of the cloth.

[0028] Working principle: the buttons are transported along the left and right directions on the nail slot assembly 2, and move to the button blocking mechanism of the button outlet plate 3 at the discharge end. At the same time, the punching knife (not shown in the figure) above the cloth presses down to cooperate with the blade 502 directly below to punch holes in the cloth, and then the button is pushed from the back to the front by the pushing assembly 4, and finally moves to the positioning groove 101 on the lower mold 10. Then the pushing assembly 4 retracts the pushing rod and prepares to push the next button. Then the punching die seat swing rod cylinder 15 extends to drive the two punching die seat swing rods to swing. The swinging of the two punching die seat swing rods can drive the punching die seat 5 to swing, so that the punching die seat 5 leaves the top of the lower mold 10 for avoidance, and then the slider cylinder 91 drives the lower mold lifting slider 9 to move forward to drive the lower mold 10 and the buttons thereon to lift, and cooperate with the upper mold of another button above to rivet the male and female buttons to the small hole position of the cloth.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
