In the utility model, on speed regulator 11, be provided with speed-regulating switch 12,, set the speed of hauling speed, just can reach the purpose of stretching and drawing band greater than the equipment of unreeling by the hauling speed that speed-regulating switch 12 can be regulated crawler belt.
In the utility model, adjusting rod 8 is arranged above last operation block 4, and be provided with spring 9 between last operation block 4 and the following operation block 3, can regulate the height of operation block 4, and guarantee that gap between the upper and lower crawler belt 7 is with the stretch thickness of back band of control by adjusting rod 8 and spring 9.
In the utility model, crawler belt 7 is a metal material, be close to the inboard upper and lower row's heating plate 10 that respectively is provided with of crawler belt 7, heat transferred crawler belt 7, finish heat-setting process in the process of stretching and drawing, owing to be that contact heat is transmitted, transmission speed is fast, crawler belt 7 is short has simultaneously avoided heat to be delivered to band inside, makes band outer ripe interior living like this.
In the utility model, crawler belt 7 can have multiple section shape according to the polytetrafluoroethylene (PTFE) band, as plane or abnormal shape.
The course of work of the present utility model is as follows: during use, traction wheel 15 under the output shaft of motor 13 drives by shaft coupling 14 on the operation block, traction wheel 15 on the following operation block is by the traction wheel on the operation block on the gear driven 5, driven pulley 16 under traction wheel 15 drives by crawler belt 7 on the operation block, traction wheel 5 drives the driven pulley of going up on the operation block 6 by crawler belt 7, the heat that heating plate 10 passes to crawler belt 7 can arrive 300 ℃～400 ℃, make the speed of the hauling speed of crawler belt by speed-regulating switch 12, in the process of stretching and drawing, finish heat-setting process greater than the equipment of unreeling.
Simple tension teflon seal tape material of the present utility model has multiple shape, flat rubber belting or surface are special-shaped, in order to make hauling machine satisfy the stretching needs of abnormally-structured band, on metal track, can process according to the shape of abnormal shape band, meet product requirement to guarantee special-shaped shape.
The beneficial effects of the utility model: use the equipment of this structure, can guarantee that band is not compacted when the stretch polytetrafluoroethylraw encapsulant, density does not change, and reaches expanded effect.By contact thermal finalization, make outer ripe interior the giving birth to of band so both to have guaranteed its flexibility simultaneously, improved intensity, creep resistant and the wearability of product again, prolonged the service life of product.
