Abstract

The utility model relates to a straw curtain braider, which is composed of a frame, a transmission mechanism, an obverse and inverse rotation swing mechanism of a driven shaft driven by a main shaft, and a thread lifting mechanism driven by a cam at the main shaft end. The main shaft and an auxiliary shaft are arranged at both sides of an intermediate shaft, the main shaft drives an eccentric wheel to achieve the thread lifting function; a connective crank achieves the functions of rotary prism swing and grass pressing through an intermediary disk; the auxiliary shaft achieves the function of grass delivery, bed knitting and progress. The utility model has the advantages of simple structure, reasonable design, double line braiding, automatic production, good strength, no tripping and high durability.

Description

Two-wire straw screen or mat automatic knitting machine

The utility model belongs to a kind of straw screen or mat braiding machine.

At present, generally using comparatively advanced straw curtain machine is 94230194, its structure is with driven by motor big belt pulley, main pulley, cranker is housed on the main shaft, crank connects with rotating shaft handles link rod, link rod one end is installed knitting needle, the other end is fixed with cutting knife by link rod, frame central is equipped with finishing plate, is fixed with the comb crank axle simultaneously, and axle head is fixed with continuous line plate, continuous line plate is connected with rocking lever, be provided with the line hole in the continuous line plate, the logical cable-through hole of the line in the drum is guided in the pinhock of knitting needle, can roll into required straw screen or mat with the reciprocating motion of knitting needle with nylon wire.The deficiency of this kind straw curtain machine structure is that to be made into straw screen or mat be single line braiding, just cut-offs uncontrollable continuation off-line continuously in case burst at the seams.

For solving the deficiency of above structure, the purpose of this utility model provides a kind of two-wire straw screen or mat automatic knitting machine, realizes that with two lines up and down locking reaches robust purpose.

The structural design of the utility model is achieved in that its structure of this braiding machine is by frame, motor and transmission mechanism (as shown in Figure 1), the driven axle rotating swing mechanism (as shown in Figure 2) of main shaft drives and the thread take-up mechanism that gear drove (as shown in Figure 3) three parts of spindle end are formed, one of them motor and transmission mechanism are in an end bottom of frame motor to be housed, motor connects the stub of frame central by belt pulley, stub connects with a main shaft and a pair axle respectively by two sprocket wheels again, at a main shaft and a pair axle two cover eccentric stiffener and link rods are housed respectively, pay eccentric shaft mechanism and make the continuous alternating movement of sending careless needle-bar work to rise and advance and descend and retreat, finish the feeding function; The thread take-up mechanism that next main wheel cam is driven is to connect rocking arm on the cam; rocking arm termination vertical fixing push rod, and the push rod top connects with the take-up main shaft, is fixed with spudger most advanced and sophisticated with holes on the take-up main shaft; be tension disk below the spudger, take-up main shaft top is fixed with drum; The driven axle rotating swing mechanism that also has main shaft drives is that crank is fixedly connected by link rod and intermediary's dish, disk center of intermediary is a driven axle, be fixed with vertical rod on intermediary's dish, rod end is a needle stand, be fixed with eedle on the needle stand, be fixed with sector gear on the driven axle simultaneously, sector gear connects with driven gear, is rotary shuttle disc in the middle of the driven gear, rotary shuttle disc is done the rotating swing, intermediary's dish connects with pressing careless tongue simultaneously, presses careless tongue around pressing the grass axle to rotate, and realizes pressing the action of grass, wherein eedle has been cut a groove on the face of cylinder above the pin hole, form one and be about 25mm, the negative area of wide about 8.5mm, it is very favourable that this penetrates wire loop to spur.

The advantage of the utility model is this machine two toe-in bail covers in the braiding process, the formation two-wire is stressed, even one thread breakage is arranged in the straw screen or mat use, straw screen or mat can not held to buckle yet and scatter, and this has just overcome the every row of original straw curtain machine all with line braiding, just makes the loose shortcoming of straw screen or mat easily as a thread breakage, Machine Design is reasonable, by the operation in a stage, reliable and stable, finish Manufacturing Automated process.

Structure of the utility model and operation principle are provided by following examples and accompanying drawing.

Fig. 2 is a two-wire straw screen or mat automatic knitting machine thread take-up mechanism structure chart;

Fig. 3 is a two-wire straw screen or mat automatic knitting machine driven axle rotating swing mechanism structure chart;

Fig. 4 is a two-wire straw screen or mat automatic knitting machine eedle structure chart.

Weaving machine structure is labeled as 1. frames by shown in the accompanying drawing; 2. motor; 3. stub; 4. thread take-up cam; 5. main shaft; 6. driven axle; 7. coupling spindle is coiled in intermediary; 8. take-up main shaft; 9. rotary shuttle disc; 10. sector gear; 11. driven gear; 12. send careless needle-bar; 13. press the grass axle; 14. platen; 15. drum; 16. pay axle; 17. spudger; 18. rocking arm; 19. push rod; 20. tension disk; 21. crank; 22. link rod; 23. rotating shaft; 24. intermediary's dish; 25. sector gear; 26. vertical rod; 27. press careless tongue; 28. needle stand; 29. eedle.

Its operation principle (as shown in Figure 1): motor 2 drives stub 3 by V belt and rotates, there are two sprocket wheels to drive main shaft 5 and 16 rotations of pair axle respectively on the stub, on main shaft and pair axle, two cover eccentric stiffener and link rods are housed respectively, send careless needle-bar 12 to do the continuous alternating movement of rising and advancing and descending and retreating thereby make, finish the function of feeding, a thread take-up cam 4 and a crank 21 are housed respectively at the two ends of main shaft 5, and thread take-up cam 4 is finished the action (as shown in Figure 2) of take-up by rocking arm 18 and push rod 19; 21 on crank makes driven axle 23 swings (as Fig. 3) by link rod 22, by intermediary's dish 24 knitting needle is moved up and down again, make rotary shuttle disc do the rotating swing by sector gear 25 and the rotating shuttle driven gear 11 that is loaded on the driven axle again, also can coil 24 in addition and drive the careless tongue 27 of pressure around pressing grass axle 13 to rotate the action that grass is pressed in realization by intermediary, eedle is in the lead-in wire stage, lift on the spudger, flow to the required line amount of eedle; After rotating shuttle entangled wire loop, spudger began line sending, satisfied to enlarge the required line amount of wire loop; When wire loop will be through the rotating shuttle frame, spudger began take-up, wire loop is close on the shuttle surface is slipped over, and allowed wire loop produce elastic force so that skid off smoothly; When wire loop when the rotating shuttle frame, spudger rises rapidly, upper thread is taken out in the rotating shuttle hang out; Before eedle descended the contact sewing for the second time, spudger tightened up stitching, pulls out the upper thread of certain-length simultaneously from bobbin, needed for next working cycles.
