Abstract
The utility model relates to a driving mechanism of a computer embroidery machine, particularly a small bent needle driving mechanism of the computer embroidery machine. The utility model solves the technical problem that the utility model provides an improvement of the small bent needle travel driving mechanism of the computer embroidery machine. The mechanism has the advantages of stable operation, reliable operation, wear-resistance, low noise, convenient installation and low cost. The utility model has the technical scheme that a drive shaft in the small bent needle driving mechanism of the computer embroidery machine drives a connecting rod to do reciprocating and rectilinear motion by a gap bridge mechanism and a reciprocating rectilinear motion mechanism. The connecting rod passes through orderly a bent needle box of each machine head and a big bent needle which is sheathed and fixed in each bent needle box, and the reciprocating rectilinear motion mechanism is an eccentric wheel mechanism. An eccentric wheel is fixed on an eccentric wheel shaft in the eccentric wheel mechanism, and the peripheral position of the eccentric wheel is rotatablely inlaid in an anchor ear which is connected with one end of the connecting rod. Both ends of the axial direction of the eccentric wheel shaft are respectively provided with a hoop cover which is fixed to the hoop so that the eccentric wheel is positioned in the hoop.
Description
Technical field
The utility model relates to a kind of transmission mechanism of computer embroidering machine, especially the transmission mechanism of the little looper of computer embroidering machine.
Background technology
All dispose the dozens of head of same structure on the existing all kinds of computer embroidering machine, every machine.Its main embroidery action is cooperated with little looper by dead in line and vertically arranged tambour needle to be finished.Be positioned at the little looper on the frame below the fabric, be installed with the embroidery line in the line eye of its top one side; The tambour needle that is positioned on the frame above the fabric then vertically down pierces through fabric, and inserts little looper central shaft hole and to certain depth; Little looper rotated a circle around vertical axis and will embroider line and twine on tambour needle this moment, then tambour needle up promotes again and breaks away from fabric, embroider in the line eye that line slips into tambour needle earlier then to be carried and pass fabric and form coil at the upper surface of fabric by tambour needle, simultaneously little looper backward rotation one circle, an acupuncture is embroidered and is finished; According to the layout action of embroidering and so forth, then can finish the embroidery action of whole embroidery.
In the head of existing machine, the outer circumference surface of each little looper and corresponding large bending needle circumferentially be shaped on gear respectively, and be meshing with each other; All large bending needles wear again and are fixed on the connecting rod 1.The rotation of little looper is (this moment, the screw thread of large bending needle played tooth bar) of being realized by the large bending needle drive of linear reciprocating motion; The linear reciprocating motion of large bending needle then is (as shown in Figure 4, the pin 30 that fork 32 1 ends are installed is embedded in the guide groove 31 of cam, and cam rotation drives the fork swing) that swing realized that endplay device produced by cam driven.Because the design of this mechanism is still owed rationally, the manufacturing of mechanism has certain degree of difficulty, and corresponding manufacturing cost is higher; In addition, the suffered impact that is embedded in the pin in the cam rail is bigger, thereby the wearing and tearing of mechanism are bigger, and the noise that produces is bigger, and environment and operating personnel are also had adverse effect.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, the improvement of the little looper transmission mechanism of a kind of computer embroidering machine is provided, this mechanism should have running steadily, reliable operation, wear-resistant, noise is little, easy for installation and lower-cost characteristics.
The technical solution adopted in the utility model is: the little looper transmission mechanism of computer embroidering machine, driving shaft in this mechanism drives a connecting rod by a mistake bridge mechanism and a linear reciprocating motion mechanism and does reciprocating linear motion, this connecting rod passes through each head looper case and suit successively and fixes large bending needle in each looper case, and described linear reciprocating motion mechanism is an eccentric mechanism.
In the described eccentric mechanism, eccentric wheel is fixed on the camshaft, eccentric circumferential location is embedded in again in the anchor ear that the end with connecting rod joins rotationally, and the axial two ends of camshaft respectively have one with the fixing hoop lid of anchor ear eccentric wheel to be positioned in the anchor ear.
Described bridge mechanism excessively is belt wheel group and gear train.
Because eccentric mechanism operates steadily, reliable operation, mechanism wear is less; Because mechanism impacts lessly, thereby noise is little, helps environmental protection and operating personnel's health again; In addition, this mechanism makes, installs all comparatively simple, and cost is also lower.
Description of drawings
Fig. 1 is the structural representation of one of them embodiment of the present utility model.
Fig. 2 is the decomposing schematic representation of Fig. 1 embodiment.
Fig. 3 is the schematic diagram of another embodiment in the utility model.
Fig. 4 is the schematic diagram of existing mechanism.
The specific embodiment
Among the embodiment by the eccentric mechanism of Figure 1 and Figure 2, eccentric wheel 4 is fixed on the camshaft 5, eccentric circumferential location is embedded in again in the anchor ear 3 that the end with connecting rod 1 joins, and anchor ear both sides (also being the axial both sides of camshaft) fixing respectively hoop lid 3-1 and 3-2 is positioned at eccentric wheel in the anchor ear.
The other end of connecting rod inserts in the axis hole of axle 16 and fixing with fixed block 15 among Fig. 2, and axle 16 and connecting rod can be relatively rotated.This part structure can directly be continued to use for the design of existing mechanism.
As shown in Figure 1, the linear reciprocating motion of this swing mechanism is driven by eccentric mechanism.The bridge mechanism of crossing that power is made up of by belt wheel group and gear train motor drives camshaft 5 rotations, and eccentric rotation drivening rod does reciprocating linear motion.
The bridge mechanism of crossing that said belt wheel group and gear train are formed is existing mechanism, can directly continue to use.Determining of its design mainly is in order to utilize the available dynamic source, to utilize the space on the existing machine.Motor 9 rotates belt wheel 8 by belt as shown in Figure 1, and by belt wheel 10 and belt wheel 12 and bevel gear 7 and 6 camshaft 5 is rotated.
In addition, motor 11 rotates axle 2 by belt and belt wheel group among Fig. 1, and by gap bridge belt wheel group in the casing 14 and carrier gear group axle 16 is rotated, and forms another driving-chain.This driving-chain also is the design of existing mechanism, is now directly used.
Among another embodiment of eccentric mechanism shown in Figure 3, an end of connecting rod 35 is positioned with bearing pin 34 on the end face of escapement 33, and escapement rotates the linear reciprocating motion that then can be converted into mechanism.
