A kind of flying cut-off saw equipment
Technical field
The present invention relates to a kind of flying cut-off saw equipment, it includes plate blank conveying device, and one is arranged on above plate blank conveying device
For blocking the mobile briar of slab, an and hydraulic means allowing mobile briar return.
Background technology
In the People's Republic of China (PRC) of State Administration of Forestry forestry industry standard LY/T1378-2004 that on December 1st, 2004 implements
Once disclosing a kind of flying cut-off saw, the driving of its saw blade operates in the top of belt conveyer, has left several millimeters even tens millis
The cutting surplus of rice, saw blade can not complete sawed-off slab, slab enter next when accelerating belt conveyer, be just stretched and draw and complete
Disconnect, result in the destruction of structure of plate slab and the decline of mechanical property, also result in simultaneously and artificially increase plate to ensure quality
The waste of the material of base length.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of briar equipment cutting slab, and it can cut off slab completely, from
And ensure the integrality of structure of plate slab and the saving of material.
To this end, the invention provides a kind of flying cut-off saw equipment, it includes plate blank conveying device, and one is arranged on slab conveying
Above device for blocking the mobile briar of slab, and a hydraulic means allowing mobile briar return, described movement
The lower section of briar arranges three transfer rollers, and three transfer rollers are positioned at the lower section of slab, and the belt of plate blank conveying device walks around three successively
Transfer roller.
After using said structure, three transfer rollers walked around by the belt of plate blank conveying device, provide cutting room for saw blade, and saw blade is cut
Just can cut off slab when cutting slab completely, thus ensure that the integrality of structure of plate slab, and then save material.
Brief description
With embodiment, the present invention is described in further details below in conjunction with the accompanying drawings.

Detailed description of the invention
With reference first to Fig. 1, this flying cut-off saw equipment, including a plate blank conveying device 2 being fed forward slab, one is blocked
The mobile briar 3 of slab, a hydraulic means 4 being placed in plate blank conveying device 2 front end.The belt 5 of plate blank conveying device 2
Through the driving wheel 21 of plate blank conveying device 2 front end, the 32nd, the 31st, the transfer roller walking around mobile briar 3 successively 33 pass through support
The 22nd, wheel 23 is walked around adjusting tensioning wheel 24 and arrives driving wheel 21. through supporting wheel 25
Slab 1 reaches above the belt 5 on driving wheel 21, and driving wheel 21 drives belt 5 to detour rotation.Slab 1 and movement
Briar 3, all travelling forward with belt 5.When mobile briar 3 runs to cutting starting point, move as shown in Figure 2
Cylinder 34 on briar 3 works, and drives moving beam 35 and mobile driving 36 decline, and the chain 37 of moving beam 35 carries
Dynamic mobile driving 36 is moved from left to right, and saw blade 38 rotation simultaneously moving driving 36 lower ends starts cutting movement.Cutting completes
After, cylinder 33 does not rises back under work, the effect of moving beam 35 and mobile driving 36 springs 30 on support bar 39
Position, on moving beam 35, chain 37 inverts return.Mobile briar 3 continues to run forward returning of arrival plate blank conveying device 2
Position position, the hydraulic means 4 being positioned at plate blank conveying device 2 front end starts, and the hydraulic stem 41 on hydraulic means 4 promotes mobile horizontal stroke
Cross cut saw 3 is returned to starting point.Hydraulic means 4, not in work, returns to the mobile briar 3 of starting point and travels forward with belt 5,
When mobile briar 3 runs to cutting starting point, the slab 1 on belt 5 will be cut, mobile briar 3 roller group
Being provided above the baffle plate 6 with intermediate space, its structure is as it is shown on figure 3, play the effect of supporting slab 1.After cutting completes
By the return position return at mobile briar 3, repeat above-mentioned process and complete the continuous fixed-length degree excision forming of slab 1.
Being appreciated that the roller group arranging three roller compositions in the lower section of mobile briar from described above, belt is walked around successively,
Just can complete saw blade to cut slab completely and do not damage belt, thus ensure the integrality of structure of plate slab and the economies of material,
The slab obtaining measured length can be cut continuously.
