Embodiment Construction

[0020] Embodiment 1 of the chain tensioner of the present invention, such as Figure 1-4 Shown: the chain tensioner includes two splints 1 and two tensioning wheels 2. Two splints 1 are arranged parallel to each other at intervals on the left and right, and each splint 1 is arranged vertically. Two tensioning wheels 2 are arranged between two clamping plates, and the tensioning wheels 2 are rotatably assembled on the clamping plates.

[0021] When in use, the thickness of the transmission chain extends along the up and down direction, and the transmission chain can move along the front and rear directions. Carry out upper and lower tensioning action to transmission chain 1. The two splints 1 and the two tension wheels 2 together form a channel 3 for the transmission chain to pass through.

[0022] Each splint 1 is provided with an adjusting long hole 4 for adjusting the distance between the axles of the two tensioning wheels, and the tensioning wheel 2 is assembled on the s...

Abstract

The invention relates to a chain tightener, a chain transmission mechanism with the chain tightener and a tobacco cutting device. The chain tightener comprises two spaced clamping plates, two tightening wheels used for tightening the two sides of a transmission chain in the thickness direction are arranged between the two clamping plates, and a channel allowing the transmission chain to pass through is defined by the tightening wheels and the clamping plates. When the chain tightener is used, the two tightening wheels can tighten the two sides of the transmission chain in the thickness direction, the problems that a single side is tightened to cause a loose side and a tight side, instant loads borne by the transmission chain are too large, and related equipment is damaged are solved, the two sides of the transmission chain can be tightened through the chain tightener, and the chain tightener cannot be damaged when the transmission chain rotates reversely.

Description

technical field [0001] The invention relates to a chain tensioner, a chain transmission mechanism using the chain tensioner and a tobacco shredded device. Background technique [0002] Chain transmission equipment transmits motion and power by the meshing of sprocket teeth and chain links, and is widely used in silk production lines. According to the length of the chain, most occasions require a tensioning device for chain transmission. The common chain tensioning device is a single-sided tensioning sprocket, which is prone to loose and tight sides. This phenomenon is more prominent when the equipment is moving in two directions. This causes the instantaneous transmission ratio of the chain transmission to be inaccurate, and there is a dynamic load in the transmission, which leads to defects such as poor performance of extreme speed reverse rotation, which easily causes the chain to be overloaded instantaneously, causing fatigue damage to the chain and causing a breakdown. ...
