Description

Punch rod mechanism and button sewing machine Technical Field The technical scheme relates to the technical field of button sewing machines, in particular to a punch rod mechanism and a button sewing machine. Background The prior riveting machine is also called button sewing machine, is widely used in clothing factories and leather bag processing enterprises, and is mainly used for sewing various types of metal buttons on knitted garments, down jackets, jeans garments, shoe caps, leather and other products. As disclosed in chinese patent 202022765785.5, the punching and feeding mechanism of riveting machine includes a servo motor and a cam assembly, the cam assembly includes a cam connected to the output shaft of the speed reducer, an eccentric shaft set on the cam, a rotating sleeve sleeved outside the eccentric shaft and a moving seat, the punching rod in the driving mode swings during lifting, which is unfavorable for the stability of punching, and the cam assembly has large integral structure and high cost, which results in large integral volume of the button sewing machine and excessively occupies space. Disclosure of Invention The purpose of this technical scheme is to provide a punch rod mechanism and button sewing machine, drives drive gear through the driving piece and rotates, and the rack portion cooperation on rethread drive gear and the movable rod realizes the lift of movable rod, and the deflection is just unstable problem when solving original movable rod and going up and down. The technical scheme aims at realizing the following steps: A punch rod mechanism comprises a mounting frame, a driving piece and a movable rod, wherein a mounting cavity is formed in the mounting frame, a transmission gear is arranged at the output end of the driving piece, the movable rod is partially and movably arranged in the mounting cavity, the lower end of the movable rod penetrates through the mounting frame to be arranged at the side of the transmission gear, a rack part is formed on the movable rod and is meshed with gear teeth of the transmission gear, and when the driving piece drives the transmission gear to rotate, lifting of the movable rod can be achieved. Preferably, the upper end face and the lower end face of the mounting frame are provided with first through holes, and the movable rod is inserted into the first through holes. Preferably, the movable rod is sleeved with two first shaft sleeves, and the first shaft sleeves are respectively arranged at the first positions of the corresponding through holes. Preferably, the punch mechanism further comprises a decelerator assembly disposed at an output end of the driving member. Preferably, the front end of the speed reducer assembly is provided with a transmission rod, and the transmission gear is sleeved outside the transmission rod. Preferably, a second through hole is formed in the side wall of the mounting frame, and the front end of the transmission rod is inserted into the second through hole. Preferably, the transmission rod is sleeved with at least one second shaft sleeve. A button sewing machine comprises a frame, wherein the mounting frame is arranged on the frame, and a punch rod mechanism. Compared with the prior art, the technical scheme has the advantages that: 1. The shaping has rack portion on the movable rod of this technical scheme design, through the cooperation of drive piece output setting's drive gear and rack portion, realizes the lift of movable rod, and this kind of transmission mode movable rod only can be in vertical direction removal, can not take place the beat, just so increased its stability of motion to drive gear and rack portion intermeshing can satisfy the single way lift distance of movable rod when drive gear rotates a small amount of number of turns, great improvement transmission efficiency. 2. The mounting bracket of this technical scheme design has the installation cavity, and the installation cavity can be spacing through self structure to the position of movable rod and transfer line, guarantees that both can counterpoint cooperation each other, save material that simultaneously can furthest practices thrift the space, and then reduce cost.
