Abstract

The utility model relates to a button sewing machine which is convenient for hand holding and carrying and is used for automatically sewing buttons. The button sewing machine comprises a swing arm used for controlling the up and down movement of a sewing needle, a moving member used for putting buttons, a thread catcher used for hooking and guiding the suture lines, and a transmission mechanism used for controlling the swing of the thread catcher. When swinging, the swing arm controls a rocking arm and swings up and down simultaneously, the rocking arm is utilized to control the thread catcher to swing right and left and hook and guide the suture line, thus stagger fastening is generated.

Description

Button sewing machine

The utility model relates to a kind of seam deduction, and especially a kind ofly conveniently hold and carry, and seam deduction that can fast automatic stitching button.

Make button and be the work that garment manufacturing industry almost must be done when making dress ornament, and when the house, have in button drops if run into, also regular meeting is sewed on voluntarily.Traditionally, the manufacturer of making button in a large number all can use button to make special machine and do stitching work, yet this kind machine belongs to relatively large machine, for being not the general family that uses often and inapplicable, increasing at home occupying of space in rain and seems comparatively uneconomical.

Therefore, the purpose of this utility model is to provide a kind of seam deduction, it is made can be for the type of hand-held operation, using provides volume very little and function is complete, and button easy and simple to handle is made special machine, and make it possess the button that is suitable for two holes and four holes to make, and can make the convenience that utilizes the cutting knife of being set up to be cut off suture when finishing and promote use at button.

Based on this, the structure of seam deduction of the present utility model is to have the swing arm that the control suture needle moves up and down, be used to put the movable part of button, be used for the thread catcher that hook draws suture, and in order to control the transmission mechanism of thread catcher swing, swing up and down simultaneously by swing arm control rocking arm when swinging, and utilize rocking arm control thread catcher to swing and suture is given hook draw and produce staggered system and consolidate, and movable part is for can do moving forward and backward of specific range on body, on this movable part, be provided with in order to the fixing clamping device of button, then be provided with a shifting part behind the set thread catcher in below, be provided with a traversing control lever after this shifting part, and between traversing control lever and shifting part, establish with flexible member, making thread catcher drive traversing control lever simultaneously when swing does swing and makes movable part move laterally, and its flexible member of mat and make activity as returning back to original position naturally, so that two adjacent button holes are able to give interpolation slit via suture needle, the side is provided with a fixture under movable part again, fixture is provided with the draw-in groove of the suitable distance of being separated by, use moving forward and backward movable part and cooperate the usefulness that defaults in the bayonet lock location below the movable part when setting institute's sewing button hole diverse location, be provided with the cutting knife that elasticity holds in the below of movable part again, can be held fixingly in advance, wait to finish and cutting knife is loosened behind the suture and be able to suture is cut off.

Below, will be described in further detail seam deduction of the present utility model in conjunction with the accompanying drawings, in the accompanying drawing:
