Abstract
The utility model relates to a fan-shaped gear and rack structure for realizing needling process and straight reciprocating motion on a needle plate through a fan-shaped gear. In a needling mechanism of a double-crank rocking rod, one end of a connecting rod is connected with the center of a fan-shaped gear which is engaged with a stable rack, and the center of the fan-shaped gear makes straight line motion. In the needling mechanism of the double-crank rocking rod, the other end of the connecting rod is connected with the center of the fan-shaped gear, and the fan-shaped gear is engaged with the stable rack. Because the rack is fixed, the center of the fan-shaped gear keeps a constant value with the engagement position of the fan-shaped gear and the rack in the process of swinging. Thus, the utility model realizes the straight line motion of the center of the fan-shaped gear, ensures the stabilization and the reliability of the movement of the needle plate, and solves the problem of oil leakage between a sliding shaft and a sliding sleeve. The fan-shaped gear and rack structure makes the sliding friction between the sliding shaft and the sliding sleeve change into the engagement of the gear and the rack, and prolongs the period of device maintenance.
Description
Technical field
The utility model belongs to non-weaving cloth production equipment technical field, relates in particular to a kind of sector gear that passes through, and realizes the sector gear and the rack structure of pricker straight reciprocating motion acupuncture course on the needle plate.
Background technology
Non-weaving cloth is the fibrous type product that directly is made of fiber, is widely used in fields such as medical sanitary, health-care material, building geotechnique material, industrial cloth material, life and family expenses ornament materials.The production process of non-weaving cloth is by becoming net, fixed, package to form.Acupuncture mechanism is a kind of consolidation method in the consolidation device.Traditional acupuncture mechanism is two the acting in conjunction of eccentric axle is housed drives needle beam and pump, and this is a kind of slider-crank mechanism in fact, and eccentric wheel becomes gyration the rectilinear motion of needle beam by the eccentric wheel cover.The sliding axle that this structure is served as slide block is reciprocating executive component, realize the motion between sliding axle and the sliding sleeve, must adopt matched in clearance between two parts, side's placed on it eccentric roller box adopts bath lubrication, lubricating oil is inevitable along the downward seepage in gap between sliding axle and the sliding sleeve, causes contamination of products.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of leakage of oil problem that can solve between sliding axle and the sliding sleeve is provided, make the sliding friction between sliding axle and the sliding sleeve change the engagement of wheel and rack into, and can prolong the realization hyperbolic axonometer thorn straight-line sector gear of mechanism's needle plate and the rack structure in maintenance of equipment cycle.
The purpose of this utility model is achieved in that in double-crank rocking bar acupuncture mechanism, an end of connecting rod links to each other with the sector gear center, and sector gear is meshed with fixed tooth bar, sector gear center moving linearly.
An end of connecting rod links to each other with the sector gear center in the double-crank rocking bar acupuncture mechanism of the present utility model, sector gear and the engagement of fixed tooth bar, because tooth bar maintains static, sector gear is in swing process, the position of engagement of its center and sector gear and tooth bar keeps steady state value one sector gear reference radius, thereby realize the rectilinear motion at sector gear center, guarantee the stable and reliable of needle plate motion, solved the leakage of oil problem between sliding axle and the sliding sleeve, also make sliding friction between sliding axle and the sliding sleeve change the engagement of wheel and rack into, prolonged the maintenance cycle of equipment.
Description of drawings
Fig. 1 is that master of the present utility model looks transmission principle figure.
Fig. 2 is the transmission principle figure that overlooks of the present utility model.
Fig. 3 is that transmission principle figure is looked on a left side of the present utility model.
Among the figure 1, main motor; 2, decelerator; 3, driving gear; 4, driven gear; 5, active bent axle; 6, by dynamic crankshaft; 7, front rod; 8, needle plate; 9, back link; 10, preceding sector gear; 11, back sector gear; 12, preceding tooth bar; 13, back tooth bar.
The specific embodiment:
As shown in Figure 1, 2, 3, the decelerator 2 that the utility model comprises motor 1, link and work under driven by motor with motor 1, link with decelerator 2 and by decelerator 2 drive be installed on the body active bent axle 5 and by dynamic crankshaft 6, on active bent axle 5, be installed with driving gear 3 by connecting key, initiatively bent axle 5 is meshed with being fixedly mounted on by the driven gear on the dynamic crankshaft 64 by connecting key by driving gear 3, and therefore initiatively bent axle 5 can drive by dynamic crankshaft 6 and active bent axle 5 synchronous counter-rotation.Bent axle is hinged by connecting rod and the needle plate 8 that is installed on the bent axle, and the gyration of bent axle becomes the rectilinear motion of needle plate 8 by connecting rod.
In double-crank rocking bar acupuncture mechanism, one end of front rod 7 and back link 9 links to each other with the center of preceding sector gear 10 with back sector gear 11, before sector gear 10 and back sector gear 11 with fixed before tooth bar 12 and back tooth bar 13 be meshed, preceding sector gear 10 and after the center moving linearly of sector gear 11.Initiatively bent axle 5, be converted to the rectilinear motion of needle plate 8 by front rod 7 and back link 9 by the gyration of dynamic crankshaft 6.For making needle plate 8 keep stable rectilinear motion, the engagement of preceding sector gear 10 and back sector gear 11 and actionless preceding tooth bar 12 and back tooth bar 13, sector gear 10 and sector gear 11 centers, back keep constant with the position of engagement distance of preceding tooth bar 12 and back tooth bar 13 always before making, the center moving linearly of sector gear 10 and back sector gear 11 before realizing.
