Description

The laser cutting machine air intake device

Technical field

The utility model relates to a kind of laser cutting device, relates in particular to the air intake device of laser cutting machine.

Background technology

Laser cutting machine is widely used in cutting metal, cloth, cladding, acrylic board, electronic circuit board etc.The conventional laser cutting machine is installed two longerons that are parallel to each other at the top of frame, the afterbody of two longerons supports active roll tube by bearing, and the front end of two longerons is by bearing supporting tensioning roller, and is connected by metal mesh belt between tensioning roller and the active roll tube.Tubaeform air draught storehouse is installed in the below of metal mesh belt, and is connected with air exhauster by exhaust column.Air exhauster work by exhaust column and air draught storehouse exhaust, is attracted on the metal mesh belt material to be processed.Because metal mesh belt is a runway shape zonary structure, the upper shed of air draught storehouse can not approach the top of metal mesh belt, and is therefore poorly sealed, the air draught poor effect.Simultaneously, tubaeform air draught chamber structure complexity, processing and assembling are difficult, can increase the production cost of complete machine greatly.

The utility model content

The laser cutting machine air intake device that provides a kind of sealing effectiveness good is provided technical problem to be solved in the utility model.

The technical solution of the utility model is as follows: a kind of laser cutting machine air intake device, two longerons that are parallel to each other are set at the top of frame, longeron is the tubular structure of closed at both ends, the front end of two longerons is by bearing supporting tensioning roller, the tail end of two longerons supports active roll tube by bearing, be connected by metal mesh belt between active roll tube and the tensioning roller, and between active roll tube and tensioning roller, be distributed with the carrying roller that is parallel to each other from front to back, each carrying roller all is positioned at the formed ring belt area of metal mesh belt, its key is: in the formed ring belt area of described metal mesh belt the air draught storehouse is set, two longeron medial surfaces between front and back end, air draught storehouse offer the inlet scoop, and the lateral surface of longeron offers air outlet, and this air outlet is connected with air exhauster by exhaust column.

The utility model in the formed ring belt area of metal mesh belt, utilizes hollow longeron to carry out air draught as air-suction channel the design of air draught storehouse.Because the upper shed in air draught storehouse can approach the top of metal mesh belt, thereby good seal, has improved the air draught effect greatly.

Above-mentioned air draught storehouse is made up of the medial surface of gas-tight silo plate and two longerons, wherein the gas-tight silo plate is the rectangular flat structure, and fixedly connected with two longerons by support, the medial surface of the dual-side of gas-tight silo plate and respective side longeron is fitted, the front and back ends of gas-tight silo plate is all to upper overturning, the corresponding carrying roller of each flange, and the end face of flange is near the bottom surface of this carrying roller.More than simple and reliable for structure, processing and assembling easily can effectively reduce the production cost of complete machine.

In order to further facilitate processing and assembling, above-mentioned longeron is the square tube of closed at both ends, and air outlet is positioned at the front portion of longeron lateral surface, and air exhauster is positioned at the place ahead of frame.

Beneficial effect: the utility model is simple in structure, processing and assembling easily, good seal, when improving the air draught effect greatly, can effectively reduce the production cost of complete machine.

Description of drawings

Fig. 1 is a front view of the present utility model.

Fig. 2 is a stereogram of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in Figure 1 and Figure 2, at the top of frame 1 two longerons 2 that distribute along frame 1 length direction are set, longeron 2 is the square tube of closed at both ends, and two longerons 2 are parallel to each other.Tensioning roller 4 is positioned at the front end at frame 1 top, and the two ends of tensioning roller 4 are bearing on two longerons 2 by bearing, and tensioning roller 4 is perpendicular with longeron 2.Active roll tube 3 is positioned at the tail end at frame 1 top, the two ends of active roll tube 3 are bearing on two longerons 2 by bearing, and active roll tube 3 is also perpendicular with longeron 2, and the driven sprocket on the active roll tube 3 is connected with drive sprocket on reducing motor 12 output shafts by chain.Be connected by metal mesh belt 5 between tensioning roller 4 and the active roll tube 3, and be distributed with the many carrying rollers that are parallel to each other 6 from front to back between active roll tube 3 and tensioning roller 4, each carrying roller 6 all is positioned at metal mesh belt 5 formed runway shape ring belt areas.Described carrying roller 6 is perpendicular with longeron 2, and carrying roller 6 is held the top of metal mesh belt 5, and can rotate with the running of metal mesh belt 5.

From Fig. 1, Fig. 2 further as can be known, in metal mesh belt 5 formed ring belt areas, the air draught storehouse is set, this air draught storehouse is made up of the medial surface of gas-tight silo plate 7 and two longerons 2, wherein gas-tight silo plate 7 is the rectangular flat structure, and fixedly connected with two longerons 2 by support, the medial surface of the dual-side of gas-tight silo plate 7 and respective side longeron 2 is fitted, and the front and back ends of gas-tight silo plate 7 is all to upper overturning, the corresponding carrying roller 6 of each flange, and the end face of flange is near the bottom surface of this carrying roller 6.On the medial surface of two longerons 2 between gas-tight silo plate 7 front and back ends, respectively offer a plurality of inlet scoops 8, and the front portion of two longerons, 2 lateral surfaces respectively offers an air outlet 9, this air outlet 9 is connected with air exhauster 11 by exhaust column 10, and air exhauster 11 is installed in the place ahead of frame 1.
