Abstract
The utility model relates to a conveying chain net tensioning device which is characterized in that slide block guide rail seats are arranged at the left side and the right side of a frame, and slide block seats are arranged in the slide block guide rail seats; positioning sleeves are arranged in connecting holes of the slide block seats; cylinders are arranged at the tail ends of the slide block guide rail seats, piston shafts of the slide block guide rail seats are connected with the slide block seats through large washers, the positioning sleeves and locking nuts, and the slide block seats are connected with a driven shaft; a chain wheel is connected to the driven shaft; and a conveying chain net is driven through the chain wheel. When the conveying chain net is needed to be tensioned, the piston shafts of the cylinders are retracted to drive the slide block seats, the driven shafts and the chain wheel to integrally move so as to tension the conveying chain net. The conveying chain net tensioning device has the advantages that the relative displacement quantity of the piston shafts and the slide block seats is reduced, so that the moving smoothness of the slide block seats is guaranteed so as to ensure that the conveying chain net can be more stable and reliable run.
Description
Affiliated technical field
The utility model belongs to carries kind equipment in the textile industry, be specifically related to carry the tightening device of link network.
Background technology
Owing to carry link network in operational process, can draw more loose and more loose, very easily cause and carry link network to break away from the phenomenon of sprocket wheel.Therefore, people will carry the drive end of link network to fix usually, and driven end adopts tightening device.Most tightening device all is that the two ends that are employed in driven shaft connect take-up housing, is moved the conveying link network is stretched, thereby will be carried the link network tensioning by cylinder drive take-up housing, driven shaft.This type of tightening device normally directly is connected in the axis of the piston of cylinder in the connection holes of take-up housing.Because the connection holes of take-up housing is more much bigger than the axis of the piston; Therefore the rate of travel of the axis of the piston and take-up housing is just big; It is not smooth when cylinder drive take-up housing moves, very easily to cause take-up housing to move; Cause the driven shaft two ends to move inconsistent and cause and carry link network pine is tight on one side on one side, may be out of shape carrying link network to squeeze when serious with frame.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model has designed a kind of new conveying link network tightening device, and this device has increased by a locating bush in the connection holes of take-up housing.
The technical scheme of the utility model is such: the slide block guide rail seat is installed in the left and right sides of frame; Take-up housing is placed in the slide block guide rail seat, and locating bush is installed in the connection holes of take-up housing, and cylinder is installed in the tail end of slide block guide rail seat; Its axis of the piston through large washer, locating bush,, jam nut, with take-up housing, link; Take-up housing and driven shaft link, and sprocket wheel is connected on the driven shaft, and conveyer chain Netcom crosses sprocket wheel and drives.When carrying link network to need tensioning, the axis of the piston retraction of cylinder, it is whole mobile to drive take-up housing, driven shaft, sprocket wheel etc., thereby will carry the link network tensioning.
The effect of the utility model is to have reduced the rate of travel of the axis of the piston and take-up housing, thereby it is smooth and easy to have guaranteed that take-up housing moves, and makes that the conveyer chain network operation is more reliable and more stable.
