Description

Three-roller

Technical field

The utility model relates to field of mechanical technique, especially a kind of three-roller that stop gauge is housed.

Background technology

Three-roller has three cylinders to be installed on the frame made of iron, and the center in a straight line.But level is installed, or inclination is arranged slightly.Be that the surperficial mutual extrusion of three rollers through level and the friction of friction speed reach grinding effect.The steel cylinder can hollow, the water flowing cooling.Material adds between central roll and back roller.Because the direction of rotation of three cylinders different (rotating speeds from then increase in order forward) just produces good abrasive action.Material is installed in the preliminary roller front after grinding scraper scrapes.Three-roller is that high-viscosity material the most effectively grinds, dispersing apparatus.Be mainly used in the grinding of liquid slurries such as various paint, printing ink, pigment, plastics, cosmetics, soap, pottery, rubber and plaster material.

Three-roller is mainly used in the grinding of high viscosity micro mist; General three-roller material directly adds between central roll and back roller; This can cause the central roll of charging aperture position and unnecessary other parts of material on the roller of back, and this a part of amount of grinding is higher than other parts, the inhomogeneous grinding on the roller axle; Can cause the uneven of roller axle surface, have a strong impact on the effect of follow-up grinding.Three-roller is very high to the requirement of roller axial plane to the fine gtinding of high viscosity micro mist, thus forbid various metal objects and hard foreign material to get into the roll of running, damage roller axial plane.

Summary of the invention

For above-mentioned problem; The purpose of the utility model is to provide a kind of three-roller that stop gauge is housed; Said stop gauge can make the material that gets into three-roller more even, can effectively prevent that various metal objects and hard foreign material from getting between the back roller and central roll of running simultaneously.

This real utility model solves the technical scheme that its technical problem adopted: this three-roller; Comprise back roller, central roll, preliminary roller, framework, stop gauge; Said stop gauge comprises blend stop, coupling assembling, and said blend stop is that the cross section is the directly rectangular of inverted V-shape, is positioned at back roller, central roll near directly over the line; The axis separately that is parallel to three rollers; V-shape two edges that said blend stop stretches out are near the external cylindrical surface of back roller, central roll, and said coupling assembling is connected in the blend stop two ends, and blend stop is fixed on said framework.

Stop gauge is loaded on roller, central roll top, back, and is parallel and be close to the external cylindrical surface of back roller and central roll, when streams is crossed space between this stop gauge and roll shaft and trickled downwards, receives and stops to both sides and trickle.More even when making material inflow back roller and central roll, and the space between stop gauge and roll shaft is very little, can prevent effectively that various metal objects and hard foreign material from getting between the back roller and central roll of running.

As preferably, said blend stop is that plastic material is made.

As preferably, said stop gauge also comprises on V-shape two edges that are loaded on blend stop, with the strip inclusion enclave of two edges parcel.

As preferably, said strip inclusion enclave, be that plastic material is made.

As preferably, when assembling, highly can regulate said coupling assembling.

As preferably, be equipped with between said central roll, the preliminary roller and the protector of stop gauge with spline structure.

The beneficial effect of the utility model is: this three-roller can make material get into three-roller more uniformly, and stressed more even with friction level when whole like this central roll and preliminary roller grind, the life-span is longer; Can prevent effectively simultaneously that various metal objects and hard foreign material from getting between the back roller and central roll of running, can effectively prevent the accidental injury of three-roller.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified:

In the embodiment shown in fig. 1; This three-roller comprises back roller 1, central roll 2, preliminary roller 3, framework 4, stop gauge 5; Said stop gauge 5 comprises blend stop 51, coupling assembling 52, and said blend stop 51 is that the cross section is the directly rectangular of inverted V-shape, is positioned at back roller 1, central roll 2 near directly over the line; The axis separately that is parallel to three rollers; V-shape two edges that said blend stop 51 stretches out are near the external cylindrical surface of back roller 1, central roll 2, and said coupling assembling 52 is connected in blend stop 51 two ends, and blend stop 51 is fixed on said framework 4.

As shown in Figure 2, stop gauge 5 is loaded on back roller 1, central roll 2 tops, and is parallel and be close to the external cylindrical surface of back roller 1 and central roll 2, when material 9 flows through space between this stop gauge 5 and roll shaft and trickles downwards, receives and stops to both sides and trickle.More even when roller 1 is with central roll 2 after making material flow into, and the space between stop gauge 5 and roll shaft is very little, can prevent effectively that various metal objects and hard foreign material 8 from getting between the back roller 1 and central roll 2 of running.

Said blend stop 51 is that plastic material makes, like this can better protection after roller 1, central roll 2, anti-stopping dam 51 is careless to damage its face of cylinder with back roller 1, central roll 2 when producing scraping.

In the another kind of embodiment of said stop gauge 5; As shown in Figure 3; Said stop gauge 5 comprises also on V-shape two edges that are loaded on blend stop 51 that with the strip inclusion enclave 53,54 of two ends parcel, said strip inclusion enclave 53,54 is made for plastic material; Blend stop 51 can use the strong material of rigidity like this, improves the bulk strength of stop gauge 5.

Highly can regulate when said coupling assembling 52 assembles, like Fig. 4 and shown in Figure 5, in a kind of embodiment of coupling assembling 52, coupling assembling 52 comprises the fixed head 521 that is fixed on the framework 4, the connecting plate 522 that an end connects blend stop 51; On the said fixed head 521 two screws are arranged, have on the said connecting plate 522 with fixed head 521 on the waist hole that matches of two screws, connecting plate 522 is fixed on the trip bolt 523 on the fixed head 521.

This three-roller can make material get into three-roller more uniformly, and stressed more even with friction level when whole like this central roll and preliminary roller grind, the life-span is longer; Can prevent effectively that simultaneously various metal objects and hard foreign material from getting between the back roller and central roll of running, can effectively prevent the accidental injury of three-roller, must this be simple in structure easy to implement, help to improve the result of use and the service efficiency of three-roller.
