Abstract
The utility model discloses a trimming regulation mechanism for a side cutter sewing machine. In the regulation mechanism, a needle rod crank is used for machining two pin holes and corresponding pin holes on a cutter cam, the cutter cam is connected with the needle rod crank, and the needle rod crank and the cutter cam are connected through a regulation pin and a regulation spring. When the motion of a cutter is required to be regulated to synchronize with or not synchronize with the needle rod crank, the regulation pin is jacked into the pin hole of the cutter cam by a tool, a drive wheel is rotated, and the then the regulation pin is shifted into another pin hole. With the adoption of the regulation mechanism, after the whole machine is assembled, a client can adjust according to different demands, and the needle rod crank is not required to be replaced; therefore, the production time is saved, and the production efficiency is improved.
Description
Technical field
The utility model relates to side cutting knife sewing machine technique field, particularly relates to the governor motion of side cutting knife flat seam machine side cut pattern.
Background technology
The former cutter mechanism operation principle of side cutting knife flat seam machine: through last axle drive needle bar crank, needle bar crank drives the cutting knife cam, and the cutting knife cam drives needle bearing and knife bar link motion again, accomplishes side cut work thereby drive whole cutter assembly.Needle bar crank and cutting knife cam are through elastic cylindrical pin be fixedly connected (like Fig. 1).The cutting knife motion is synchronous with shank, can cut obtuse angle edge, like coat collar; The cutting knife motion is asynchronous with shank, can cut right-angle side, like the pointed collar of shirt.Existing cutter mechanism realizes through changing needle bar crank whether the cutting knife motion is synchronous with shank.The replacing needle bar crank is wasted time and energy, mounting or dismounting inconvenience, and the needle bar crank of same size needs different structures, manufactures also cumbersome.
The utility model content
The governor motion of a kind of side cutting knife flat seam machine side cut pattern that the utility model technical problem to be solved is to propose to existing technical problem in the above-mentioned prior art; This governor motion will have two pin-and-holes of processing on the needle bar crank of governor motion now; Step pin-and-hole of processing is used for install adjustment pin and regulating spring on the cutting knife cam, is connected needle bar crank and cutting knife cam with regulating spring through regulating pin; Through regulating the position of pin I, II pin-and-hole on needle bar crank; Realize that synchronously whether cutting knife motion and shank, no longer need change needle bar crank, the client can oneself adjust according to different demands.
The technical problem that the utility model requires to solve can realize through following technical scheme:
The governor motion of side cutting knife flat seam machine side cut pattern comprises needle bar crank, knife bar cam, knife bar connecting rod, needle bearing, guide rail, slide block, cutter assembly, and said needle bar crank is connected with the knife bar cam; Said knife bar cam is socket needle bearing and knife bar connecting rod successively outward; Said knife bar connecting rod connects cutter assembly down, and slide block is arranged on the said cutter assembly, and said slide block places in the guide rail; Can slide up and down along guide rail; Said needle bar crank main body is a circular-arc base portion, has a cylinder protruding directly over the said base portion, and said needle bar crank top, the left and right sides, the protruding bottom of cylinder symmetry have two pin-and-holes; On the said knife bar cam to any step pin-and-hole should be arranged; One in two pin-and-holes on this step pin-and-hole and needle bar crank is inserted the adjusting pin, to connect needle bar crank and knife bar cam, said adjusting pin below pad regulating spring.
One end of said knife bar cam has the shaft shoulder, begins a theatrical performance the rank pin-and-hole on the said shaft shoulder plane.
Said shaft shoulder thickness is 3.3mm.
Open a through hole in addition on the said knife bar cam, be used to place straight pin, through straight pin at the fixing thrust washer of knife bar cam tail end.
Owing to adopted technique scheme, the utlity model has following beneficial effect: after final assembly was good, the client can oneself adjust according to different demands just can realize that the cutting knife motion is synchronous or asynchronous with shank; Do not need to change in addition needle bar crank.
Description of drawings
Fig. 1 is existing cutter mechanism structure chart.
Fig. 2 is the utility model cutter mechanism structure chart.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 2, the utility model comprises needle bar crank 1, knife bar cam 6, regulates pin 4, regulating spring 5, knife bar connecting rod 2, needle bearing 3, guide rail 7, slide block 8, cutter assembly 9, straight pin 10, thrust washer 11.Needle bar crank 1 is connected with knife bar cam 6, knife bar cam 6 outer socket needle bearings successively 3 and knife bar connecting rod 2, and knife bar connecting rod 2 connects cutter assembly 9; Slide block 8 is arranged on the cutter assembly 9; Slide block 8 places in the guide rail 7, can in guide rail 7, slide, and does rectilinear motion up and down thereby limit cutter assembly 9; Regulate pin 4 and place in any pin-and-hole on the needle bar crank 1 with regulating spring 5 and in the step pin-and-hole 61 of knife bar cam 6, thereby connect needle bar crank 1 and knife bar cam 6, step pin-and-hole 61 is of a size of φ 5/ φ 3mm; Also have a through hole 62 on the knife bar cam 6, straight pin 10 is positioned in this through hole 62, and through hole 62 diameters are φ 4mm, and thrust washer 11 is fixed on knife bar cam 6 rear portions through straight pin 10.
Drive knife bar cam 6 by needle bar crank 1, and then drive knife bar connecting rod 2, connect through knife bar, 2 drive whole cutter assembly, finally accomplish the side cut task.The client will adjust the synchronous or asynchronous of cutting knife motion and needle bar crank 1; Only need tool using that the adjusting pin 4 in I among Fig. 2 or the II hole is pushed in the step pin-and-hole 61 on the knife bar cam 6; Rotate the Sewing machines driving wheel simultaneously, change to regulate pin 4 and on needle bar crank 1, get final product the position in I or II hole.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; 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 variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
