Abstract

The utility model relates to a portable bag sealer. A kinematic pair which is at the oscillation center of a needle bar rocker in a needle bar mechanism of an existing portable bag sealer is in the form of kinematic pair forms of a cylindrical shaft and a shaft sleeve to replace a conic tail kinematic pair in the utility model. A lubricating oil storage device is arranged at the movable point of a main kinematic pair so as to enable the main kinematic pair to keep a running state with lubricating oil. The portable bag sealer can keep a normal running state durably under the condition that the accumulative gap of a needle bar mechanism is tiny.

Description

Portable bag closer

The utility model relates to a kind of Sewing machines, particularly a kind of portable bag closer.

Seal the GK9 type portable bag closer of usefulness behind the industry packaging bag storages such as at present domestic and international chemical industry, chemical fertilizer, grain, sugaring, warehouse, be formed by connecting by gear (worm gear, worm screw pattern) by head of sewing machine and motor; Head of sewing machine is made up of casing, needle bar mechanism (effect of eedle thorn material lead-in wire), string-hooking mechanism (the swing crochet hook colludes line, forms chain-type stitch) and feed mechanism.Needle bar mechanism mainly is made up of driving members such as garden column cap round pin screw, big connecting rod, shank rocking bar, awl tail screw, small rod, shank connecting axle and shanks.Worm gear on needle bar mechanism and the main shaft (end face of worm gear is provided with a position, plays the crank effect) hinge.During the starter motor running,, make the eedle of sewing machine needle bar mechanism do straight reciprocating motion by the speed change of worm and wormwheel.The said mechanism weak point is: the oscillation center awl uropore of shank rocking bar is loosening easily with cooperating of the awl tail kinematic pair of awl tail screw, and lubricating oil is difficult for correctly being added to activity place of each component movement pair, make the kinematic pair of each member be in seldom lubricating oil state or the running down of unlubricated oil condition, thereby cause the component movement pair to wear and tear, the accumulation gap of needle bar mechanism is increased, cause mechanical disorder.

The utility model purpose is in the component movement pair to the architecture advances of the kinematic pair of shank rocking bar oscillation center and mechanism Fuel Tanking Unit to be set, and the lubricating condition of its kinematic pair is improved, and prolongs machine a kind of portable bag closer of normal service time.

The purpose of this utility model is achieved in that the kinematic pair of the oscillation center of shank rocking bar substituted the kinematic pair form of awl tail (60 degree) by the kinematic pair form of cylinder axis, axle sleeve, increases the lubricating oil Fuel Tanking Unit in activity place of main kinematic pair.The state that main kinematic pair is in lubricating oil turns round down.The accumulation gap that reaches needle bar mechanism is in a kind of portable bag closer that runs well enduringly under the very little state.

In conjunction with the accompanying drawings concrete structure of the present utility model is elaborated again with embodiment below.

Be portable bag closer complete machine of the present utility model in Fig. 1, it is made up of I sewing machine head, II motor, III gear and IV frame etc.The relative position figure that head of sewing machine mainly is made up of I-1 needle bar mechanism, I-2 feed mechanism and I-3 string-hooking mechanism.

In embodiment illustrated in fig. 2, main shaft (2) is gone up the end face of worm gear (5) and is loaded onto big connecting rod cylinder screw (7) (crank effect) and big connecting rod hinge, and the big connecting rod other end and needle bar crank (10) are gone up big connecting rod cylinder screw (7) hinge; It is fastening with two screws that needle bar crank axle (11) is housed in the oscillation center hole of needle bar crank, two ends of axle are installed on the axle position of casing (1) with needle bar crank front shaft sleeve (14) and needle bar crank rear axle housing (13) respectively, the other end of needle bar crank is equipped with small rod round pin screw (15), and with small rod (16) shank connecting axle (17) hinge, in the shank axle sleeve (19) of shank (18) on casing and fastening with shank connecting axle (17).Eedle (22) is contained in the shank (18) fastening by the screw (21) of pin folder (20).When driving worm gear (5), worm screw (6) makes big connecting rod, needle bar crank, and the small rod hinge moves together, and needle bar crank is made reciprocally swinging, and the interlock shank pumps.

The movable place of the mechanism kinematic pairs of this machine is the lubrication circumstances explanation between attrition surface between each part: three grooves and worm-gear toothing root intermediate connection are arranged at the oil storage tank bottom of worm gear (5) (seeing Fig. 4 in detail), lubricating grease is contained in storage in the oil storage tank, lubricating grease enters worm-gear toothing portion through three grooves in oil storage tank bottom, the centrifugal force that lubricating grease in the oil storage tank produces by machine run, make lubricating grease constantly enter worm-gear toothing portion, make worm couple that good lubricating condition be arranged.There is an oil storage hole at the cylinder axis center of two big connecting rod cylinder screws (7), after wick (8) is housed in the hole injects lubricating oil, by oilhole on the cylinder axial plane with lubricating oil on the attrition surface of big connecting rod hole and axle.In small rod round pin screw (15) one overhung cranks of shank rocking bar (10) an oilhole passage is arranged; On the plane in the middle of two holes of small rod (16) groove is arranged; In the middle of needle bar crank axle (11) axle hole being arranged is oil storage hole, and wick (12) is housed in the hole, and this axle has three oil outlets and groove of end face, and a groove is used for aiming at the middle oilhole passage of shank rocking bar (10) on the end face; When injecting wick (12), lubricating oil make lubricating oil pass through the attrition surface of two axles of three oilholes inflows of this oil storage hole, flow in the groove of small rod (16) and centre, two holes of small rod with oilhole passage in the needle bar crank, making in the attrition surface of small rod all has lubricating oil, and the lubricating oil of small rod enters in shank (18) and the shank axle sleeve (19) again.(when machine uses, needle bar crank axle (11) is perpendicular to the ground, (see figure 3) unscrews casing upper cover plate bolt (24) rotating plate (23) and can inject the wick place of enough lubricating oil in (12) (8) (3) when shank (18) state parallel to the ground) adding lubricating oil, perhaps adds lubricating grease in the oil storage tank of worm gear (5).
