Abstract
The utility model provides a chain type sewing machine with a side cutting knife, which comprises an upper rotating shaft connected with a crank-link mechanism. A needle rod is connected with the crank-link mechanism, a machine needle is arranged at the front end of the needle rod, and a bent needle is arranged below the machine needle. The chain type sewing machine is characterized in that: the upper shaft is also connected with a cam mechanism, the cam mechanism is connected with a reciprocating mechanism by a connecting rod, and the reciprocating mechanism is connected with a cutting knife mechanism. The chain type sewing machine with the side cutting knife can carry out sewing at the same time as cutting materials, so as to ensure stable distance between a stitch and the rim of sewing materials, and improve the product grade; as the material cutting and sewing are finished on the same sewing machine, the investment for fixed equipment is reduced, the working efficiency is increased, and the product cost is lowered.
Description
Technical field
The utility model relates to the sewing machine technique field, concrete relates to a kind of two-wire chain type Sewing machines.
Background technology
Two-wire chain type Sewing machines is meant the Sewing machines of the chain form stitching that is formed by two lines (a staight needle line and a looper thread) reciprocation cycle string cover, chain type Sewing machines characteristics and purposes: the firm and high resilience of stitching, be applicable to the clothes underwear, the overlapping the slot of bedding and leather and fur products, ornamental seam.
Two-wire chain type Sewing machines structure as shown in Figure 1, last axle 1 ' rotate drives needle bar crank 2 ' rotations, needle bar crank 2 ' by connecting rod 3 ' make shank 4 ' move up and down, eedle 5 ' be contained in shank 4 ' front end, follow shank 4 ' move up and down and make the thorn material and move.Looper 6 ' under the special exercise track, with eedle 5 ' cooperate, form chain-type stitch.
The shortcoming of said structure is, when uneven or operating technology is not high when the cutting of sewing edge, will cause the stitching after the sewing irregular to the distance at sewing edge, and visual effect is undesirable, can feel that the class of sewings is lower to the people like this.If stitching is equal to the distance maintenance at sewing edge, just need purchase the equipment of a special-purpose blank again, will increase extra input like this, reduce production efficiency, increase product cost indirectly.
The utility model content
Technical problem to be solved in the utility model is, overcomes problems of the prior art, and a kind of side cutting knife chain type Sewing machines is provided.
In order to address the above problem the technical solution of the utility model is such:
A kind of side cutting knife chain type Sewing machines, comprise a upward axle that rotates, last axle connects a toggle, toggle connects a shank, and the shank front end is provided with an eedle, and the eedle below is provided with a looper, it is characterized in that, the described axle of going up also connects a cam mechanism, and cam mechanism connects a reciprocator by a connecting rod, and reciprocator connects a cutter mechanism.
Described reciprocator comprises that one connects the connecting rod of cam, and connecting rod connects a slide bar that slides up and down, and the slide bar lower end connects an operating key, but the connection cutter mechanism of described operating key clutch.
Described cutting knife controlling organization comprises a knife rest, has a clutch slot that is used to connect operating key on the knife rest, and knife rest one end is fixedly connected with cutting knife, and the cutting knife below is provided with the stationary knife that cooperates with cutting knife.
The advantage of the utility model side cutting knife chain type Sewing machines: sewing in the time of blank, guaranteed the stable distance of stitching to the sewing edge, promote product specification, blank is finished on same Sewing machines with sewing, reduce the input of permanent plant, improved operating efficiency, reduced product cost.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is existing two-wire chain type Sewing machines structural representation;
Fig. 2 is a side cutting knife chain type Sewing machines structural representation described in the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 2
A kind of side cutting knife chain type Sewing machines comprises a upward axle 1 that rotates, and last axle 1 connects a crank 2, and crank 2 connects a connecting rod 3, connecting rod 3 connections one shank that moves up and down 4, and shank 4 front ends are provided with an eedle 5, and eedle 5 belows are provided with a looper 16.Eedle 5 and looper 16 complement each other to form the chain form stitching.The described axle 1 of going up also connects a cam 6, cam 6 connects a connecting rod 7, connecting rod 7 connects a slide bar that can slide up and down 9, axially be provided with a position limiting slide block that slides up and down 8 in connecting rod 7 and slide bar 9 junctions, slide bar 9 lower ends connect an operating key 11, operating key 11 laterally has a clutch spring 10, operating key 11 laterally connects a cutting knife installing rack 14, cutting knife installing rack 14 middle parts have a clutch slot A, operating key 11 is connected with clutch slot A disengaging type, and cutting knife installing rack 14 is arranged on a crossbearer 13, cutting knife installing rack 14 can crossbearer 13 on move left and right, cutting knife installing rack 14 1 ends are fixedly connected with cutting knife 12, are provided with the stationary knife 15. that cooperates with cutting knife 12 below cutting knife 12
The blank sewing of the described side cutting knife of present embodiment chain type Sewing machines is carried out simultaneously, the concrete course of work is: go up axle 1 rotation drive needle bar crank 2 and rotate, needle bar crank 2 moves up and down shank 4 by connecting rod 3, eedle 5 is contained in the front end of shank 4, follows moving up and down of shank 4 and does the action of thorn material.Looper 12 under the special exercise track, cooperate with eedle 5, form chain-type stitch; Simultaneously, eccentric cam 6 rotates around last axle 1, drive connector 9 by connecting rod 7 and do vertical motion up and down, connector 5 drives cutting knife control piece 11 again and moves up and down, if when wanting automatic trimming, need depress cutting knife installing rack 14, then the front end of control piece 11 can insert among the elongated slot A, realize knife rest 14 vertical motion about control piece 11 is done, at this moment, cutting knife and stationary knife 15 are made the blank action.If when not needing blank, only need control piece 11 is spurred to the right, at this moment, control piece 11 is thrown off with cutoff knife rack, and Sewing machines is only done the sewing action.
The described side cutting knife of present embodiment chain type Sewing machines is sewed in blank, has guaranteed the stable distance of stitching to the sewing edge, promotes product specification, blank is finished on same Sewing machines with sewing, reduce the input of permanent plant, improved operating efficiency, reduced product cost.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
