Abstract
The utility model discloses a back combing eccentric connecting rod transmission mechanism for a two-needle bar warp knitting machine. The back combing eccentric connecting rod transmission mechanism consists of an eccentric connecting rod, a connecting rod frame, a shaft, connecting plates, a small shaft, a connecting rod, a main transmission shaft, a connecting nut, a joint-containing connecting rod, a guide bar swing arm and a guide bar pendulum shaft, and is characterized in that: one end of an eccentric connecting rod assembly is connected to the main transmission shaft; the other end of the eccentric connecting rod assembly is fastened on the small shaft; the two ends of the small shaft are connected with the connecting rod and one ends of two connecting plates through needle bearings respectively; the other ends of the connecting plates are fastened with the shaft; the middle of each connecting plate is axially positioned through a spacer sleeve; the two ends of the shaft are arranged on the connecting rod frame through a needle bearing; and the main transmission shaft is rotated to drive a four-connecting-rod mechanism consisting of the eccentric connecting rod to move. Compared with the prior art, the back combing eccentric connecting rod transmission mechanism has the advantages: the reliability of a machine is enhanced, and the production efficiency is increased; and the utility model can be generally suitable for back combing eccentric connecting rod transmission mechanisms for Raschel two-needle bar warp knitting machines.
Description
Technical field
The utility model relates to the transmission mechanism of warp knitting machine loop-forming element, particularly relates to comb eccentric ratio transmission mechanism behind the La Sheer double rib warp loom.
Background technology
According to the characteristics of La Sheer double rib warp loom,, effectively control the sley bar swing for realizing its lopping kinetic characteristic; Two main axle structures are set behind machine, much higher because of the speed of back comb main shaft than other, be three times of other spindle speed; Usually in the machine braiding process, cause this associated part wearing and tearing easily.Cause above-mentioned situation; Tracing it to its cause mainly is that the eccentric ratio transmission mechanism receives the influence of locus on the comb main shaft of back, combs eccentric ratio after adding and directly links to each other with kinematic link, causes back comb transmission device cantilever long; Locate bad; In motion process, produce axial float, thereby, back comb eccentric ratio generation deviation phenomenon caused.
Summary of the invention
After overcoming existing double rib warp loom, comb the above-mentioned defective that eccentric ratio moves, the utility model is combed the eccentric ratio transmission mechanism after a kind of double rib warp loom is provided, and with its structure of further optimization, makes its reliable motion, helps raising labour productivity.
For solving its technical problem, the technical scheme that the utility model adopts is: comb eccentric ratio transmission mechanism behind the double rib warp loom of designing, by eccentric ratio; Connecting rod rest, axle, connecting plate; Little axle, connecting rod, final drive shaft; The attaching nut contains the connecting rod of joint, and sley bar swing arm and sley bar balance staff are formed; Its feature is: 1. on final drive shaft, be connected with an end of eccentric ratio conjunction, the other end of this eccentric ratio conjunction is fastened on the little axle, and the two ends of little axle are connected to an end of connecting rod and two connecting plates through needle bearing; The other end of connecting plate is fastening with axle, and axial location is carried out by spacer in the centre of connecting plate, and the two ends of axle are installed on the connecting rod rest through needle bearing; Through rotating final drive shaft, drive the above-mentioned parallel motion that comprises that eccentric ratio is formed.2. the other end of said connecting rod links into an integrated entity with the connecting rod that contains joint through the attaching nut; The other end of this connecting rod is linked to each other with the sley bar swing arm by fastening bolt; The other end of sley bar swing arm is fixed on the sley bar balance staff through half slide structure; The sley bar balance staff is rotated, thereby effectively realize the motion of back comb eccentric ratio transmission mechanism.
Compared with prior art; Because the utility model is to be connected with little axle through the eccentric ratio that is installed on the machine transmission main shaft; Little axle two ends link to each other with connecting plate with kinematic link respectively, and little axial location is reliable, prevent the eccentric ratio axial float and cause deviation phenomenon; The other end of connecting plate is fixing with axle, and simultaneously, axle leans on the connecting rod rest supporting, and forms quadric chain; Kinematic link on the little axle directly drives to back comb balance staff through swing arm; Guaranteed the accuracy of back comb motion; Make the kinematic link that is installed on the little axle by the curvilinear motion that designs, and rotate, thereby reach back comb eccentric ratio stability of transmission by sley bar swing arm control sley bar balance staff.Improved the reliability of machine, the production efficiency of machine improves thereupon, can generally be applicable to comb eccentric ratio transmission mechanism behind the La Sheer double rib warp loom.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the connecting plate of the utility model and the broken section structural representation of little axle and shaft connection place;
Fig. 2 is the lateral cross section structural representation of the utility model.
Among the figure: 1 eccentric ratio, 2 connecting rod rests, 3,4 connecting plates, 5 little axles, 6 connecting rods, 7 final drive shafts, 8 attaching nuts, 9 contain the connecting rod of joint, 10 sley bar swing arms, 11 sley bar balance staffs.
The specific embodiment
With reference to accompanying drawing: an end of eccentric ratio conjunction 1 is installed on the final drive shaft 7; The other end of eccentric ratio conjunction 1 is fastened on the little axle 5; The two ends of little axle 5 are connected with the end of connecting rod 6 with two connecting plates 4 by needle bearing respectively; The other end of connecting plate 4 is fastening with axle 3, and axial location is carried out by spacer in the centre of connecting plate 4, and the two ends of axle 3 are installed on the connecting rod rest 2 through needle bearing.Through rotating final drive shaft 7, drive the above-mentioned parallel motion that comprises that eccentric ratio 1 is formed; Link into an integrated entity through attaching nut 8 with the connecting rod 9 that contains joint by the connecting rod 6 that is connected on the little axle 5 again; The other end of connecting rod 9 is linked to each other with sley bar swing arm 10 by fastening bolt; The other end of sley bar swing arm 10 is fixed on the sley bar balance staff 11 through half slide structure; Sley bar balance staff 11 is rotated, thereby effectively realize the motion of back comb eccentric ratio transmission mechanism.
