Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Refer to Fig. 1 to Fig. 3, the invention provides a kind of Sewing machines trimming thread ends, comprise workbench, be located at sewing device on workbench and dust bucket, described dust bucket is connected with a hose 1; Described hose 1 one end is connected with a casing 2; Described casing 2 one end has an opening 3; The suction spool road 4 through each other with hose 1 is provided with in described casing 2; An installation pipeline 5 is provided with in described casing 2; Described suction spool road 4 is through each other with opening 3; Cutting facility is provided with in described installation pipeline 5; Described opening 3 place is provided with a cutter stator 6 matched with cutting facility; The motor shaft that described cutting facility comprises the first motor 7, first motor 7 is connected with a connection piece 8; Described connector 8 is provided with an eccentric shaft; Described eccentric shaft is connected with a bearing 9;
Described cutter stator 6 is provided with a stage clip holder 10; Described stage clip holder 10 is provided with a stage clip 11; Described stage clip 11 is connected with blade oscillates block 12; Described blade oscillates block 12 is provided with a U-shaped frame 13; Described bearing 9 is between U-shaped frame 13; A cutting blade 14 is provided with below described blade oscillates block 12; Described casing 2 is provided with a starting switch 15 be connected with the first motor 7; Described casing 2 sidewall is provided with a chute 16; Described chute 16 bottom is provided with a screw; Described chute 16 is provided with taking-up frame 17, and taking-up frame 17 is provided with a through hole 18; One adjusting nut 19 is fixed in screw through through hole 18, and makes taking-up frame 17 be close to chute 16; Described casing 2 is provided with messenger wire mouth 20; Described casing 2 is made up of with right casing 22 left casing 21;
Described cutter stator 6 is provided with some equidistant stationary knife teeth 23 to each other; Described cutting blade 14 is provided with some equidistant moving knife teeth 24 to each other; In the teeth groove 25 that described moving knife tooth 24 is formed between two stationary knife teeth 23; Described opening 3 place is provided with a Thread odds suction support 26; Cutter stator 6 side is blocked by described Thread odds suction support 26.
Described cutting blade 14 material is ceramic material.
Described taking-up frame 17 lower end is provided with an eave tile 27.
Described bearing 9 is roller bearing.
Described left casing 21 is fixed by screw 28 with right casing 22.
Using method of the present invention is as follows:
When needing to sew to cloth, cloth is placed on the table, by the sewing device on workbench, cloth is sewed, when needing after a part of sewing work completes to wipe out the end of a thread on cloth, originally the casing 2 hung aside by messenger wire mouth 20 is taken off by staff, then will hold outside casing 2, and make the direction of opening 3 towards the end of a thread that need wipe out of casing.
Now coupled hose 1 is made to produce suction by opening dust bucket, along with the generation of hose 1 suction, the suction spool road 4 connected with hose 1 also produces suction simultaneously, the end of a thread that this suction need be wiped out is drawn in opening 3, then the starting switch 15 be located on casing is pressed, first motor 7 is brought into operation, because the motor shaft of the first motor 7 is connected with connector 8, and connector 8 is provided with eccentric shaft, therefore when the first motor 7 runs, eccentric shaft does eccentric motion along with the first motor 7, and eccentric shaft is connected with bearing 9, and between the U-shaped frame 13 of bearing 9 on blade oscillates block, therefore when eccentric shaft carries out off-centre operation, bearing 9 also starts to do eccentric motion, and the track of eccentric motion is oval, make bearing 9 when doing eccentric motion and U-shaped frame 13 liang of inwalls touch, and make U-shaped frame 13 swing.
Along with swinging of U-shaped frame 13, blade oscillates block 12 swings thereupon, cutting blade 14 is provided with below blade oscillates block 12, and blade oscillates block 12 is connected the steadiness that ensures between the two with cutting blade 14 by inlay card mode, therefore when blade oscillates block 12 swings, cutting blade 14 also swings thereupon, because the moving knife tooth 24 on cutting blade 14 is positioned at the teeth groove 25 of stationary knife tooth 23 formation, therefore along with moving knife tooth 24 swings, moving knife tooth 24 and stationary knife tooth 23 touch, and form cutting force, now the end of a thread is made to enter in the teeth groove 25 of stationary knife tooth formation by suction, and the end of a thread is wiped out rapidly by the cutting force touching generation with stationary knife tooth 23 by the moving knife tooth 24 swung, if the end of a thread cannot be drawn in opening 3 by suction, then taking-up frame 17 is made no longer to be close to chute 16 by turn adjusting nut 19, the taking-up frame 17 loosened can move down at the track of chute 16, eave tile 27 below it is moved down thereupon, when taking-up frame 17 position moves to and enough carries out take-up work, taking-up frame 17 is made to be close to chute 16 by adjusting nut 19, no longer loosening, after taking-up frame 17 position adjustments is good, just cannot be triggered by the end of a thread that suction is drawn by eave tile 27, it is made to enter in opening 3, the end of a thread wiped out is drawn by suction into after in opening 3, enter in dust bucket eventually through hose 1 along suction spool road 4.
Because the swing of cutting blade 14 is driven by the first motor 7, therefore avoid because artificial trimming causes the situation that trimming efficiency is extremely low, even and if continual the end of a thread to be wiped out, trimming efficiency also can not reduce, and while wiping out the end of a thread, the end of a thread wiped out can be cleared up, avoid the trouble that staff's later stage carries out clearing up, also there will not be because the end of a thread dropped on the table causes the affected situation of sewing work.
After trimming work completes, during without the need to carrying out trimming, by adjusting nut 19, taking-up frame 17 is moved to original position, prevent eave tile 27 couples of staff of taking-up frame from damaging, and single line rope can be used to make cotton rope form an annular hoisting ring through messenger wire mouth 20, in order to hanging somewhere, casing 2 is laid.
Can rub with cutter stator 6 when cutting blade 14 cuts, long friction can make cutting blade self-temperature rise, if cutting blade is metal material, at high temperature cutting blade very easily abrasion deformation, but what the material of cutting blade 14 of the present invention adopted is ceramic material, ceramic material is high temperature resistant, and red hardness is splendid, make cutting blade 14 at high temperature not fragile, ensure that its service life, and cutter stator 6 is metal material, cutting blade 14 is ceramic material, because cutter stator 6 and cutting blade 14 are different materials, there is not compatibility each other, therefore cutter stator 6 and cutting blade 14 are more difficult to damage in the process of constantly touching.
