Description

A kind of staight needle of engineering Sewing machines and bearded needle sewing structure
Technical field
The utility model relates to industrial sewing machine technical field.Be specifically related to a kind of staight needle and bearded needle sewing structure of engineering Sewing machines.
Background technology
Sewing machines is that one forms stitching, the machine that one deck or which floor sewing are stitched together on sewing.Sewing machines is generally used for the sewing of braided fabric, artificial leather, leather.
Along with development in science and technology, present many construction materials, industrial materials etc. all need the stitching of some packing materials and surfacing, occur the Sewing machines that these coarse fodders are sewed up thereupon.But the machine needle structure more complicated of the Sewing machines that these engineerings are used, working procedure is also more loaded down with trivial details, thereby has had a strong impact on production efficiency.Therefore need one simple in structure, the Sewing machines that sewing efficiency is high, is its important improvement but eedle hooks line structure.
Utility model content
The utility model, in order to address the above problem, overcomes machine needle structure complexity, the defect that sewing efficiency is low.The utility model proposes a kind of staight needle and bearded needle sewing structure of engineering Sewing machines.
To achieve these goals, the technical solution of the utility model is as follows:
The staight needle of engineering Sewing machines and bearded needle sewing structure comprise that operating desk, bogie side frame, motor drive driving shaft, eccentric mechanism, a movable connecting rod, staight needle movement frame, presser feet motion, staight needle, looper driving shaft, curved needle shaft, looper motion string-hooking mechanism, looper.Described operating desk is located in the middle of two bogie side frames, described motor drives driving shaft to be provided with eccentric wheel and driving member one, described eccentric wheel connects motor and drives driving shaft and movable connecting rod, and described movable connecting rod connects staight needle movement frame, and described staight needle and presser feet motion are located on staight needle movement frame; Described driving member one connects motor and drives driving shaft and looper driving shaft, and described looper driving shaft is connected with curved needle shaft by driving member two, and looper motion string-hooking mechanism is housed on described curved needle shaft, and described looper motion string-hooking mechanism is provided with looper.
Further, described driving member one is or/and driving member two is gear or sprocket wheel.
Further, described looper motion string-hooking mechanism is rotating shuttle or shuttle.
Further, apart from ground, high 1.4-1.5 rice is provided with tool box to described bogie side frame.
The beneficial effects of the utility model are, this Sewing machines can be worked by driven by motor staight needle and looper simultaneously, greatly enhances productivity, and this utility model is rational in infrastructure, and mechanism is simple, and science is suitable for.
Brief description of the drawings
Fig. 1 is the staight needle of a kind of engineering Sewing machines of the utility model and the structural representation of bearded needle sewing structure.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect in understanding understanding, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the staight needle of this project Sewing machines and bearded needle sewing structure comprise operating desk 500 and bogie side frame 600, on operating desk 500, be distributed with some pin holes, the quantity of every row's pin hole is identical with staight needle, operating desk 500 is located in the middle of two bogie side frames 600, bogie side frame 600 is provided with tool box 900, motor 100 and motor drive driving shaft 200 to be arranged on below bogie side frame 600, motor drives driving shaft 200 to be provided with eccentric wheel 300 and driving member 1, eccentric wheel 300 is connected with movable connecting rod 310, movable connecting rod 310 is connected with staight needle movement frame 400, staight needle motion pin 400 is provided with staight needle 410 and presser feet motion 420, motor drives the driving member 1 on driving shaft 200 to be connected with looper driving shaft 700, looper driving shaft 700 is connected with curved needle shaft 720 by driving member 2 710, driving member 1 is or/and driving member 2 710 is that gear is or/and sprocket wheel, curved needle shaft 720 is connected with looper motion string-hooking mechanism 730, looper motion string-hooking mechanism 730 is rotating shuttle or shuttle, looper motion string-hooking mechanism 730 is provided with looper 740.Material enters from the entrance of operating desk 500, first through presser feet motion 420, material is compressed to location, then driven by motor motor drives driving shaft 200 to rotate, motor drives driving shaft 200 to rotate and then is with action to pump staight needle movement frame 400 through eccentric wheel 300, staight needle 410 sews up material, now motor drive driving shaft 200 by gear or and chain gear transmission looper driving shaft 700 rotate, looper driving shaft 700 by gear or and chain gear transmission looper motion string-hooking mechanism 730 move, and then drive looper 740 to move, the shuttling movement that coordinates by the lower material of staight needle 410 seams with looper 740, thereby complete the single line chain type sewing work of staight needle 410 and looper 740.
