Description

A kind of rice conveying automatic takeup in sterile rice processing

Technical field

This utility model belongs to food processing equipment, the rice conveying auto-tensioning in specifically a kind of sterile rice processing Device.

Background technology

Strainer is belt, conventional holding meanss on chain transmission system, is characterized in keeping belt, chain passing Suitable tensile force being had during dynamic, thus avoiding belt slippage, or avoiding Timing Belt to occur to jump tooth, take off tooth and drag Go out, or prevent chain-loose, come off, mitigate sprocket wheel, chain wear.Traditional strainer needs separately to provide a set of driven Wheel stretching belt, structure is relative complex, and can increase the running resistance of belt feeder, increased the load of power source.

Content of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides the rice in a kind of sterile rice processing automatic with conveying Tensioner is it is ensured that while conveyer belt has suitable tension force over pulleys carried, simplify the structure of traditional strainer.

For realizing above-mentioned technical purpose, the scheme that this utility model provides is：Rice in a kind of processing of sterile rice is with defeated Send automatic takeup, including belt feeder driven pulley and tensioning cylinder, the piston of tensioning cylinder passes through bearing block directly and belt The axle of machine driven pulley connects, and tensioning cylinder is by being provided with the pipeline connection pressure source of pneumatic control valve, the rodless cavity of tensioning cylinder It is equipped with pressure regulator valve with rod chamber.

And, described tensioning cylinder has two, is respectively arranged at the two ends of the axle of driven pulley, by respective piston, axle Bearing connects the axle two ends of driven pulley.

The beneficial effects of the utility model are：Tensioner directly acts on the driven pulley of belt feeder, simplifies tradition Strainer needs the structure separately providing a set of driven pulley to stretch belt, decreases the resistance of belt feeder；Tensile force is adjustable, full Foot difference working condition requirement.

Specific embodiment

Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.

The present embodiment provides the rice conveying automatic takeup in a kind of sterile rice processing, as shown in figure 1, including skin Band machine driven pulley 1 and tensioning cylinder 4, the piston of tensioning cylinder 4 is directly connected with the axle of belt feeder driven pulley 1 by bearing block 3, Tensioning cylinder 4 is equipped with by being provided with the pipeline connection pressure source of pneumatic control valve 6, the rodless cavity of tensioning cylinder 4 and rod chamber Pressure regulator valve 5.

Further, as shown in Fig. 2 described tensioning cylinder 4 has two（First cylinder 4.1 and the second cylinder 4.2）, respectively It is arranged at the two ends of the axle of driven pulley 1, connect the axle two ends of driven pulley 1 by respective piston, bearing block.

During work, open pneumatic control valve 6 and supply tensioning cylinder 4, tensioning cylinder 4 promotes driven pulley by bearing block 3 1, driven pulley 1 drives belt 2 tensioning, and tensile force size is adjusted by pressure regulator valve 5.

The above is only preferred implementation of the present utility model it is noted that common skill for the art For art personnel, on the premise of without departing from this utility model principle, can also make some improve or deform, these improve or Deformation also should be regarded as protection domain of the present utility model.
