Description
One, technical field:
The present invention relates to Sewing machines trimming, over casting technical field, be specifically related to a kind of Sewing machines with trimming, bound edge, the three-in-one operation of sewing.
Two, background technology:
Only have single needle trimming, hemming sewing machine at present, but need the dress ornament of two-wire mark bound edge just to need first to use single needle side cutting knife Sewing machines excision burr if run in clothes processing, then use general sewing machine over casting.
Prior art Problems existing is: processing technology is complicated, and waste of manpower resource, capacity utilization is not high
Three, summary of the invention:
The present invention, in order to solve the weak point in above-mentioned background technology, provides a kind of Sewing machines with trimming, bound edge, the three-in-one operation of sewing, and complicated to solve the processing technology existed in prior art, waste of manpower resource, equipment investment costly.
For achieving the above object, the technical solution used in the present invention is: one has trimming, bound edge, the Sewing machines of three-in-one operation of sewing, comprise head of sewing machine and base plate, the motion end of described head of sewing machine is provided with eedle and presser feet, described base plate is provided with needle plate below relative eedle, feed dog is provided with below needle plate, it is characterized in that: the shank inboard track installing rack of described head of sewing machine, described guide rail installation frame is provided with guide assembly, the planar ends of guide assembly is provided with cutting knife installing rack, the lower end of described cutting knife installing rack is provided with cutter assembly, described base plate is provided with hemmer installing plate, hemmer installing plate is provided with hemmer, the discharging opening of hemmer is arranged between needle plate and presser feet, described base plate is provided with support, described support is provided with power transmission shaft, the two ends of power transmission shaft are connected to front crank and rear crank, slide block is provided with in " U " type groove of described front crank, described slide block is by axial screw and cutting knife installing rack, described rear crank is vertically connected with cam link mechanism, described cam link mechanism is vertically arranged in base plate and is connected with the lower shaft bottom base plate.
The structure of described support is " U " type.
Compared with prior art, the advantage that has of the present invention and effect as follows:
1. increase work efficiency:
1.1, two-needle sewing machine trimming, two procedures is disposable completes in sewing; 1.2, two-needle sewing machine bound edge, two procedures is disposable completes in sewing; 1.3, two-needle sewing machine trimming, bound edge, sewing three process is disposable completes, and makes production efficiency improve more than 50%.
2. cost-saving: a machine replaces the function of two machines, equipment cost saves about 50%, and labour cost saves about 50%.
3. sewing efficiency is better: two procedures unites two into one and can to reduce in process machine and human factor to the pollution of cloth and damage.
Four, accompanying drawing illustrates:

Fig. 3 is structural representation of the present invention;
Fig. 4 is the partial sectional view in B portion in Fig. 3;
Reference numeral: 1-head, 2-base plate, 3-cam link mechanism, 4-rear crank, 5-guide assembly, 6-cutter assembly, 7-cutting knife installing rack, 8-presser feet, 9-feed dog, 10-needle plate, 11-eedle, 12-hemmer installing plate, 13-support, 14-power transmission shaft, crank before 15-, 16-axial screw, 17-slide block, 18-hemmer, 19-guide rail installation frame.
Five, detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:
See Fig. 1-Fig. 4: one has trimming, bound edge, the Sewing machines of three-in-one operation of sewing, comprise head of sewing machine 1 and base plate 2, the motion end of described head of sewing machine 1 is provided with eedle 11 and presser feet 7, described base plate 2 is provided with needle plate 10 below relative eedle 11, feed dog 9 is provided with below needle plate 10, the shank inboard track installing rack 19 of described head of sewing machine 1, described guide rail installation frame 19 is provided with guide assembly 5, the planar ends of guide assembly 5 is provided with cutting knife installing rack 7, the lower end of described cutting knife installing rack 7 is provided with cutter assembly 6, described base plate 2 is provided with hemmer installing plate 12, hemmer installing plate 12 is provided with hemmer 18, the discharging opening of hemmer 18 is arranged between needle plate 10 and presser feet 8, described base plate 2 is provided with support 13, the structure of described support 13 is " U " type, described support 13 is provided with power transmission shaft 14, the two ends of power transmission shaft 14 are connected to front crank 15 and rear crank 4, slide block 17 is provided with in " U " type groove of described front crank 15, described slide block 17 is by axial screw 16 and cutting knife installing rack 7, described rear crank 4 is vertically connected with cam link mechanism 3, described cam link mechanism 3 is vertically arranged in base plate 2 and is connected with the lower shaft bottom base plate 2.
Use procedure of the present invention: lift presser feet 8, put into cloth; Bound edge cloth enters bottom presser feet along hemmer 18; Machine turns, lower shaft drives cam link mechanism 3, power is sent to guide assembly 5 by cam link mechanism 3, guide assembly drives 5 cutter assemblies 6 to start to move up and down, cloth burr cuts away, after bound edge cloth bottom the cloth cutting away burr and presser feet converges, eedle starts sewing, and trimming, over casting operation terminate.
Existing head will realize two-wire mark trimming bound edge function, control cost again, unified head blank and head processing, cutting knife power resources are very scabrous problems, and mechanism considers the advantage of double needle lockstitch machine lower shaft movement characteristic and cam mechanism and guide rail, by convert rotational motion for pumping, realize trimming function, do not increase head blank again, reduce cost, after this cover mechanism is removed, common crosspointer machine can also be worked as and use.
