Description
Technical field:
The utility model relates to sews with long stitches rust machine technology field, the routing mechanism of refering in particular to a kind of embroidering machine.
Background technology:
Embroidering machine is a kind of machinery of giving the lining processing graphic pattern, has routing mechanism to be used for defeated line on embroidering machine and cooperates and sew with long stitches the embroidery art and do.All independently cam drive and thread take-up tension lever assembly are formed more by overlapping in rotating shuttle routing mechanism on the general embroidering machine, its weak point: the one, taking up room of every cover thread take-up tension lever assembly is big, make that the spacing between per two thread take-up tension levers is bigger, and then make the spacing between per two pins can not lean on too closely, thereby just can not design the colored type of being embroidered too little, the performance of embroidering machine can not be brought into play fully; The 2nd, because every cover thread take-up tension lever assembly is independent, make the complex structure of every cover thread take-up tension lever assembly, processing and fabricating is time-consuming bothersome, the fault rate height, the maintenance difficulty is big.
Have subsequently by the routing axle and drive the routing mechanism that a routing bar carries out routing, this designs simplification overlaps the thread take-up tension lever assembly more, is combined into an integral body; But because the driving-chain design defect, the swing that makes the routing axle is not very smooth and easy, causes the routing instability, and influence is produced.
Summary of the invention:
It is a kind of simple in structure that the purpose of this utility model is to provide, transmission smoothness, the routing mechanism of improving the embroidering machine of routing quality.
For achieving the above object, the utility model adopts following scheme:
The routing mechanism of embroidering machine, comprise routing axle and the routing bar that links with the routing axle, the routing bar is provided with several through wires holes and is used for take-up, it is characterized in that: power source coordinates to construct the routing action of routing bar through a four-bar mechanism and a five-rod, wherein, four-bar mechanism comprises the final drive shaft that connects power source, eccentric wheel, composite rod, connecting rod I and a countershaft that connects main rotary shaft, and connecting rod I two ends are articulated in composite rod and countershaft respectively, and countershaft then is installed on the frame; Five-rod comprises countershaft, connects connecting rod I, composite rod, connecting rod II, rocking arm and the routing axle of countershaft, and connecting rod II two ends are articulated in composite rod and rocking arm respectively, and the rocking arm other end is fixed on the routing axle.
The utility model is simplified routing mechanism, coordinate to construct the routing action of routing bar by a four-bar mechanism and a five-rod, the coordinated movement of various economic factors of two mechanisms can effectively avoid occurring the motion dead point, guarantees that the swing of routing axle and routing bar is smooth and easy, improves the stability and the quality of routing action; Can reduce simultaneously wearing and tearing and abnormal sound between the driving member, prolong and use.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model partial structurtes decomposing schematic representations;
Accompanying drawing 3 is the combining structure side view of the utility model;
Accompanying drawing 4 is the routing schematic diagram of mechanism of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
See shown in the accompanying drawing 1～4 that the routing mechanism of embroidering machine described in the utility model comprises routing axle 10 and the routing bar 11 that links with routing axle 10, routing bar 11 is provided with several through wires holes and is used for take-up, and through wires hole can be selected to use.Power source coordinates to construct the routing action of routing bar through a four-bar mechanism and a five-rod, wherein, four-bar mechanism comprises the final drive shaft 20 that connects power source, eccentric wheel 21, composite rod 30, connecting rod I41 and a countershaft 42 that connects main rotary shaft, connecting rod I 41 two ends are articulated in composite rod 30 and countershaft 42 respectively, and 42 of countershafts are installed on the frame.Five-rod comprises countershaft 42, connects connecting rod I41, composite rod 30, connecting rod II 51, Rocker arm 52 and the routing axle 10 of countershaft, and connecting rod II 51 two ends are articulated in composite rod 30 and Rocker arm 52 respectively, and Rocker arm 52 other ends are fixed on the routing axle 10.
Shown in Figure 1, there is synchronous power input at routing axle 10 two ends, promptly are equipped with four-bar mechanism and five-rod at routing axle 10 two ends and cooperate transmission.Shown in Figure 2, composite rod 30 is installed on the final drive shaft 20 through eccentric wheel 21 off-centre, composite rod 30 is the connecting rod of three hinge holes, realize the switching of four-bar mechanism and five-rod, connecting rod I 41 hinged composite rods 30 and realize the movement locus of control composite rod 30, thus make the motion of exporting on composite rod 30 outer ends satisfy the routing requirement.Connecting rod II 51 is connected composite rod 30 and Rocker arm 52, is that the Rocker arm 52 that moves through that will export on composite rod 30 outer ends passes to routing axle 10, makes routing axle 10 obtain the routing motion, promptly realizes the ceaselessly defeated line of routing bar 11.
Shown in Figure 3, four-bar mechanism of the utility model and five-rod cooperate ingenious, simple in structure, and installing space is little, thus easy disassembly.Shown in Figure 4, Principle of Mechanical Designing is satisfied in the utility model design, and four-bar mechanism and five-rod harmony are good, and motion is smooth, so that the routing motion stabilization of output, also reduces wearing and tearing and abnormal sound between the driving member.Among Fig. 4, A is a final drive shaft 20, and D is a countershaft 42, and AB is an eccentric wheel 21, and BC and CE are composite rod 30, and DC is connecting rod I 41, and EF is connecting rod II 51, and GF is a Rocker arm 52, and G is a routing axle 10.
In the present embodiment, the power of motor output passes to final drive shaft 20 through driving belt, i.e. power source input, and final drive shaft 20 is passed to four-bar mechanism and five-rod simultaneously with power, the two mechanisms coordinated movement of various economic factors and construct the routing action of routing bar 11 also just realizes the routing work of embroidering machine thus.
