Abstract
The utility model provides a batcher chain tensioning device, because be provided with the spout on the dead lever, the slide bar can remove in the spout, and the center pin is installed on the slide bar, and wheel body installs on the center pin, so the running roller can remove along with the slide bar to adjust the elasticity of chain, the bearing clamp is established between wheel body and center pin, so wheel body can wind center pin flexible rotation, can not influence the transmission of chain, consequently, the utility model discloses a batcher chain tensioning device conveniently adjusts the elasticity of chain.
Description
Technical field
This utility model belongs to mechanical transmission fields, is specifically related to a kind of batcher chain stretching device.
Background technology
Screw(-type) feeder is to integrate the conveying of powder material current stabilization, Weighing and the new generation product of fixing quantity；It is applicable to powder material continuous metering and the dispensing of various industrial production environment.Part helix batcher, particularly some factories, in some technical process, when needing with screw(-type) feeder continuous feed, due to some requirements to equipment or technique, it is thus desirable to screw(-type) feeder provides one end of the rotary shaft of device the employing Chain conveyer, i.e. screw(-type) feeder of driving force be designed as gear, it is connected with the gear drive being fixed on machine shaft by chain.But, chain, during long-play, is understood stress stretcher strain, can be relaxed, therefore need the elasticity often dismantling chain to adjust chain between chain and two gears, the most time-consuming, and arduously；For the problem that can relax after chain long-play, some patents install tensioner additional for chain, but, tensioner can not flexible.
Summary of the invention
The purpose of this utility model is to provide a kind of convenient batcher chain stretching device regulating chain degree of tightness.
This utility model provides a kind of batcher chain stretching device, including: fixing bar 10, sliding bar 20 and running roller 30, wherein, it is provided with chute 11 on described fixing bar 10, one end of described sliding bar 20 is slidably mounted on described chute 11, and described running roller 30 comprises: the central shaft 32 being arranged on the other end of sliding bar 20, the running roller body 31 being arranged on central shaft 32 and the bearing 33 being folded between running roller body 31 and central shaft 32.
Medicated pillow of the present utility model can also be further improved and limit: the cross section of fixing bar 10 is arranged on the side of fixing bar 10 as " U " type, chute 11.Convenient installation.
Medicated pillow of the present utility model can also be further improved restriction: central shaft 32 is removably mounted on the other end of sliding bar 20.Facilitate the replacing of running roller 30.
Batcher chain stretching device involved by this utility model, because being provided with chute on fixing bar, sliding bar can move in chute, central shaft is arranged on sliding bar, roller body is installed on center shaft, so, running roller can move along with sliding bar, make the chain with running roller contact side towards or away from opposite side chain movement, thus regulate the elasticity of chain；Bearing is folded between roller body and central shaft, so, roller body can not interfere with the transmission of chain, therefore, the convenient degree of tightness regulating chain of batcher chain stretching device of the present utility model around central shaft flexible rotating.

Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reaching purpose and be easy to understand with effect, following example combine accompanying drawing and are specifically addressed batcher chain stretching device of the present utility model.
As shown in Figure 1 and Figure 2, batcher chain stretching device comprises: fixing bar 10, sliding bar 20 and running roller 30.One end of sliding bar 20 is slidably mounted on fixing bar 10, and running roller 30 is removably mounted on the other end of sliding bar 20.
Fixing bar 10 is by bracing members, and cross section is " u "-shaped, and the one side of fixing bar 10 arranges chute 11.One end of sliding bar 20 is screw rod, is slidably mounted on chute 11, and fixes with nut 21, and the other end of sliding bar 20 is hollow stem.As it is shown on figure 3, running roller 30 comprises: running roller body 31, central shaft 32 and two bearings 33.Running roller body 31 is arranged on central shaft 32, and two bearings 33 are folded between running roller body 31 and central shaft 32, and two bearings 33 are positioned at the two ends of running roller body 31, it is possible to make running roller body 31 rotate around central shaft 32 neatly, thus do not affect the transmission of chain 40.The diameter of central shaft 32 matches with the internal diameter of hollow stem, and central shaft 32 is plugged in hollow stem, facilitates the replacing of running roller 30.
Running roller body 31 is arranged on the outside of chain 40, fixing bar 10 is fixed in the frame of surrounding according to the position of running roller body 31, sliding bar 20 moves in chute 11, running roller body 31 is along with movement, the distance making chain 40 both sides reduces, thus reaches the purpose of tension chain 40, and when running roller body 31 compresses chain 40, add the engagement wrapping angle of the sprocket wheel 60 of the sprocket wheel 50 fixing with motor and batcher, improve transmission efficiency.
Above-mentioned embodiment is preferred case of the present utility model, is not intended to limit protection domain of the present utility model.
