Abstract
The invention discloses a needle blocking mechanism of a straight-tube type sewing machine, which is used for stabilizing a sewing needle when the sewing needle of the sewing machine is inserted downwards to a sewing platform so as to avoid the phenomenon that the sewing needle is broken or jumped due to the shaking of the sewing needle caused by high-speed movement; the invention includes a needle guard and a transmission mechanism, the needle guard includes a movable body and front and rear needle guards, wherein the rear needle guard is fixed on the movable body, and the front needle guard is spanned on the movable body, when the transmission mechanism provides force to make the movable body of the needle guard do reciprocating motion, the front needle guard swings reversely with the reciprocating motion, and when the sewing needle is inserted downwards, the front needle guard is close to the rear needle guard, so as to stabilize the swaying sewing needle.
Description
Technical field
The present invention relates to a kind of needle protector of straight barrel type Sewing machines, particularly a kind of when using Sewing machines, the stable needle protector that produces the straight barrel type Sewing machines of the sewing pin that rocks because of high-speed motion.
Background technology
The sewing industrial technology has reached the quite skillful stage, more how soon fast easy Sewing machines arranged now, be used for factory and produce ready-made clothes in a large number, early stage Sewing machines tramps with one's feet with manual type one pin one line profit and cooperates people's hand operated to finish, the factory of overwhelming majority sewing now all comes the indirect labor with full automatic working, reaches the purpose that increases production efficiency and reduce cost with this.
Because industrial sewing machines all require to reach the function of high efficiency production, and it is fast and reduce the broken needle probability and be inevitable if will reach this function sewing velocity, existing sewing machine all adopts high-speed motor to accelerate sewing velocity, yet, though use high-speed motor can allow speed promote, but the sewing pin can produce under high-speed motion and rock, because inserting needle speed is fast downwards, adding the sewing pin rocks, make the broken needle chance increase, thereby need to interrupt sewing work, causing trouble, can't enhance productivity on the contrary.
The needle protector of existing straight barrel type Sewing machines (seeing also Fig. 1), be that front pin 13a is connected in down on the looper 40, and along with controlling axostylus axostyle 41 interlocks of looper 40 down, behind the downward inserting needle of sewing pin (not shown), and when preparing upwards needle, this at present looper 40 begin action, prepare to pass the yarn (not shown) of lopping, and then drive front pin 13a near backstop pin 12a; And backstop pin 12a is connected on the feeding tooth 42, this feeding tooth 42 is driven by connecting rod 43, and then promote backstop pin 12a and front pin 13a close, and the sewing pin is slightly clamped, yet this needle protector is when the sewing pin is about to begin make progress needle, just the sewing pin is clamped, and its forward and backward retaining pin 13a, 12a drive with different axostylus axostyles 41 and connecting rod 43 respectively, and be bad if its time point is grasped, and causes broken needle or bouncing pilotage situation easily.
Summary of the invention
Main purpose of the present invention is to provide a kind of sewing pin of straight barrel type Sewing machines, can stablize a kind of mechanical structure of sewing, and it comprises:
One retaining pin device comprises a mobile, backstop pin, and front pin, and this backstop pin is connected in this mobile top, and this front pin is striden and is located at the mobile top, and does oscillating traverse motion;
One transmission mechanism, comprise rotary main shaft, steering mechanism and interlinked mechanism, this rotary main shaft provides a revolving force, and join with this steering mechanism, and this steering mechanism changes over above-mentioned revolving force and the orthogonal reciprocating motion of this rotary main shaft, utilizes this interlinked mechanism that this power is passed to aforesaid retaining pin device again.
Another object of the present invention is to provide a kind of needle protector of self contained function, utilize aforesaid steering mechanism and interlinked mechanism, with the needle protector self contained function, and must respectively forward and backward retaining pin be attached to down on looper and the feeding tooth as existing needle protector, utilize the action of its axostylus axostyle and connecting rod more respectively, in addition, because its independent design, thus can adjust separately needle protector mutually near with the time difference of separating, with the downward inserting needle that cooperates the sewing pin and upwards the withdraw of the needle move.
