Abstract
The utility model relates to a chain transmission technology of a feeder in the tobacco industry, and discloses an automatic double-side tensioning chain pressing mechanism. The automatic double-side tensioning chain pressing mechanism is provided with a driving chain wheel, a driven chain wheel, a transmission chain, a double-side tensioning spring, rotating arms and chain pressing wheels, wherein the driving chain wheel and the driven chain wheel are mounted at two ends of the transmission chain, the chain pressing wheels are mounted on both a loose side and a tight side of the transmission chain, the center of each chain pressing wheel is fixed at one end of one rotating arm, the other end of each rotating arm is fixed on a machine frame of equipment, and two ends of the double-side tensioning spring are connected with the rotating arms. Through the arrangement, the effects that the automatic double-side tensioning chain pressing mechanism works reliably and the chain transmission is stable are guaranteed, the service life of the chain transmission is prolonged, and the operation reliability of the equipment can be improved at the same time.
Description
Technical field
The utility model relates to the chain drive technology of feeder in tobacco business, especially relates to a kind of bilateral auto-tensioning and presses chain mechanism.
Background technique
The chain transmission is the mechanical transmission that a kind of quilt extensively uses, and arranged during operation dividing of slack list and pilled-in selvedge.For guaranteeing to operate steadily, improve working life, the slack list needs pretension in some way, prevents that chain from beating.In tobacco business, the feeder that is widely used, its transmission that turns net is also the chain transmission, but its working condition is different from general chain transmission.Be mainly reflected in running, under the effect of wind-force, especially start moment, turn the chaindriven slack list of net and pilled-in selvedge and can occur alternately to change, thereby affect chaindriven working life.For preventing that chain from beating, the technology that adopts at present is that separate automatic tensioning mechanism is adopted, the major defect of this technology in both sides: bilateral tension force is determined difficulty, presses the chain tensioning mechanism easily to lose efficacy during operation, impacts large.
Existing auto-tensioning presses chain mechanism (referring to Fig. 1) to be provided with drive sprocket 14, driven sprocket 11, drive chain 12 and monolateral tensioning mechanism 13, described 12 are connected with driven sprocket with drive sprocket 14 respectively and are connected, and are provided with separate left and right automatic tensioning mechanism 13 on drive chain 12 both sides.
Summary of the invention
The purpose of this utility model is to provide and can solves slack list and pilled-in selvedge chaindriven smooth running problem occurs to guarantee when alternately changing, and presses chain mechanism with the bilateral auto-tensioning that improves chain transmission working life.
The utility model is provided with drive sprocket, driven sprocket, drive chain, bilateral tension spring, cursor and pressing sprocket;
Described drive sprocket and driven sprocket are arranged on respectively the two ends of drive chain; The slack list of described drive chain and pilled-in selvedge all are equipped with pressing sprocket, and the center of pressing sprocket is fixed on an end of cursor, and the other end of cursor is fixed on the frame of equipment, and the two ends of bilateral tension spring are connected with cursor.
The beneficial effects of the utility model show: guarantee the chain tensioning mechanism reliable operation, chain transmission is steady, improves chain transmission in the time of working life, improves the equipment reliability of operation.
Description of drawings
Fig. 1 is that existing auto-tensioning presses the structure of chain mechanism to form schematic diagram.
Fig. 2 is that the utility model embodiment's structure forms schematic diagram.
Embodiment
Referring to Fig. 2, the utility model embodiment is provided with drive sprocket 26, driven sprocket 21, drive chain 22, bilateral tension spring 23, cursor 24 and pressing sprocket 25.Described drive sprocket 26 and driven sprocket 21 are arranged on respectively the two ends of drive chain 22; The slack list of described drive chain 22 and pilled-in selvedge all are equipped with pressing sprocket 25, and the center of pressing sprocket 25 is fixed on an end of cursor 24, and the other end of cursor 24 is fixed on the frame of equipment, and the two ends of bilateral tension spring 23 are connected with cursor 24.
Automatic tensioning mechanism of the present utility model is installed axis take principal and subordinate's movable sprocket as benchmark, the slack list of drive chain and pilled-in selvedge are all installed pressing sprocket, the pressing sprocket center is fixed on a wherein end of cursor, the other end is fixed on equipment rack, and can freely rotate centered by the immovable point of stander end in the working plane of drive chain, the two ends of bilateral tension spring are connected with the intermediate connection point of cursor respectively, the tension force of two ends adjustable springs.During work, first suitably drive chain is carried out pretension, when the slack list of drive chain and pilled-in selvedge changed, two pressing sprockets of automatic tensioning mechanism were along with the edge slack of chain alternately changes and is subjected to displacement, guarantee that the slack list is in tensioning state all the time, reach the purpose of stablizing chain transmission.
Claims (1)
