Abstract

The utility model discloses a wire guide wheel for a square cutting machine. The wire guide wheel comprises an aluminum ring body and an outer-circle polyurethane layer. The wire guide wheel for the square cutting machine has the characteristics that a plurality of uniformly distributed keyways are arranged at the joint between the aluminum ring body and the outer-circle polyurethane layer; the section of each keyway is semicircular; the keyway structure is sunken toward the internal part of the aluminum ring body. Moreover, four, six or eight keyways are arranged on the aluminum ring body. As a preferable scheme, four equant keyways are arranged on the aluminum ring body; the included angle between the adjacent two keyways is 90 degrees, and the keyways are uniformly distributed on the aluminum ring body. The wire guide wheel has a simple structure, is easy to process and achieves the purpose of preventing the aluminum ring body from slipping in high speed running and reversing process of the wire guide wheel when a crystal bar is cut; and the cutting size of the square cutting machine is more stable and accurate.

Description

Butt machine guide roller

Technical field

The utility model relates to the butt machine, particularly is applied to have on the butt machine guide roller of anti-slip effect.

Background technology

Solar energy is subjected to people's favor just day by day as a kind of cleaning, efficient and never depleted new forms of energy, and national governments are also competitively with the important behave of solar energy resources utilization as the national sustainable development strategy.

Monocrystalline silicon and polysilicon are requisite materials during solar energy utilizes, its consumption is also increasing, the butt machine is a visual plant of making monocrystalline silicon and polysilicon, guide roller on the butt machine is used for the trend and the operation stability of crystal bar cutting process control line of cut, reaches the stable purpose of cut lengths.

In monocrystalline silicon, polycrystal silicon ingot butt process, process unit adopts layer of polyurethane can dial guide roller in order to save cost mostly, the problem that occurs in the use is: outer ring polyurethane layer and body aluminium circle are because the infiltration of cutting mortar, in the high-speed cruising commutation process, outer ring polyurethane layer and body aluminium circle can skid.The friction of skidding can cause the outer experience wear of body aluminium circle to diminish, and then causes and can dial the polyurethane pull-up and fall, and produces broken string.

The utility model content

In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of butt machine guide roller, has effectively avoided skidding between outer ring and the body aluminium circle by architecture advances, has protected body aluminium circle not frayed, makes to produce normal operation.

To achieve these goals, the technical solution of the utility model is as follows:

Butt machine guide roller comprises body aluminium circle and outer ring layer of polyurethane, is characterized in, the joint with the outer ring layer of polyurethane on described body aluminium circle is provided with several equally distributed keyways, plays the effect of anti-slip.

Further, four, six or eight keyways are set on the described body aluminium circle, are uniformly distributed on the described body aluminium circle.

As preferred version, on the described body aluminium circle four keyways are set, the angle between adjacent two keyways is 90 degree, is uniformly distributed on the described body aluminium circle, anti-slip purpose in the high-speed cruising commutation process when reaching the crystal bar cutting.

Further, the cross section semicircular in shape of described keyway, keyway arrangements is to body aluminium circle inner recess.

The beneficial effects of the utility model are, and are simple in structure, are easy to processing, effectively avoided skidding between outer ring and the body aluminium circle, protected body aluminium circle not frayed, make to produce normally to move, and the cut lengths of butt machine are more stable, accurate.

The specific embodiment:

Be easy to understand understanding in order to make creation characteristic of the present utility model, technological means and to reach purpose, further set forth the utility model below in conjunction with specific embodiment.

Embodiment:

Referring to Fig. 1, Fig. 2 and Fig. 3, butt machine guide roller comprises body aluminium circle 1 and outer ring layer of polyurethane 2, and is evenly distributed on the keyway 3 on the body aluminium circle 1.

As preferred version, the joint of body aluminium circle 1 and outer ring layer of polyurethane 2 is provided with the keyway 3 of four five equilibriums, angle between adjacent two keyways 3 is 90 degree, is uniformly distributed on the described body aluminium circle 1, anti-slip purpose in the high-speed cruising commutation process when reaching the crystal bar cutting.

The cross section semicircular in shape of each keyway 3, keyway arrangements is to body aluminium circle 1 inner recess.

As shown in Figure 4, outer ring layer of polyurethane 2 is for can dial layer of polyurethane, the outside of body aluminium circle 1 is set, effectively avoided guide roller body aluminium circle 1 and the phenomenon that outer ring layer of polyurethane 2 skids in the high-speed cruising commutation process by being provided with of keyway 3, the size when making the cutting of butt machine is more stable, accurate.

In the foregoing description, body aluminium circle 1 also can evenly be provided with six or eight keyways as required with the joint of outer ring layer of polyurethane 2, play the effect of anti-slip, consider the factor of cost, four keyways are optimum implementation, processing cost is low, prevents that the purpose that body aluminium circle 1 and outer ring layer of polyurethane 2 skid from also having reached.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand, and the utility model is not restricted to the described embodiments, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
