Abstract

Welded tube tendon duct winding machine feed frame steel band is anxious stops roll-switching device; the unwinding rack of welded tube tendon duct winding machine installs steel coil strip; nip rolls installed by the support of unwinding rack rear end; above nip rolls, pressure roller is installed; the rotating shaft of nip rolls is connected with change speed gear box; change speed gear box is connected with drive motor; at the rear side of nip rolls, storage cassette holder is installed; forward (FWD) registration roller is installed in storage cassette holder front end; band registration roller is installed out in rear end; be buffered in after steel band is bending in storage cassette holder, be provided with compression cylinder at the two ends of pressure roller, pressure roller is pressed on nip rolls by compression cylinder.Adopt the technical program, in process of production, when a upper coil band is finished, only need the cylinder using pressure roller two ends, upper pressure-raising roller, make the distress resolves between nip rolls and steel band, namely steel band stops traction, and the tail end of steel band just can stop at reel position immediately, after now workman carries out change of lap, be easy to the welding just carrying out steel band at same position, steel band welding speed is accelerated greatly, and the tape splicing working strength of workman reduces greatly.

Description

Welded tube tendon duct winding machine feed frame steel band is anxious stops roll-switching device
Technical field
The utility model belongs to ratio-frequency welded tube processing technique field, relates to a kind of welded tube tendon duct winding machine feed frame steel band and suddenly stops roll-switching device.
Background technology
In the ratio-frequency welded tube course of processing, the steel band of rolling will be connected into steel pipe with ratio-frequency welding again after tendon duct winding machine roller is pressed into prefabricated pipe.Because steel band is hard, the steel band of rolling is when uncoiling is drawn to tendon duct winding machine, and artificial traction is more difficult, in process of production, need at the end of a upper coil band unreels, next coil band taken the lead to be welded on the tail end of a upper coil band, the tractive force of dependence tendon duct winding machine draws.In prior art, because steel band is directly drawn on tendon duct winding machine, steel band is vertical bar shape substantially, when a upper coil band is used up, whole piece pipe crimping manufacturing line is needed to stop, its tail end just can stop, and just can carry out the welding of next coil band, this mode of production, the continuity of producing is caused to be interrupted, production efficiency reduces, and causes the welded tube of welding bay to be scrapped simultaneously, and the energy consumption of production increases.
For addressing this problem, people devise one group of nip rolls, pressure roller and a storage cassette holder between tendon duct winding machine and the unwinding rack of steel band, when a upper coil band unreels close to tail end, haulage speed is accelerated with the nip rolls set up, the steel band bent storage between nip rolls and tendon duct winding machine is made to store up in cassette holder, at the end of the steel band in steel coil strip unreels, close nip rolls, feed is continued with the steel band in storage cassette holder, now, carry out quick change of lap, the front end of next coil band is welded to the tail end of a upper coil band, guarantees that pipe crimping work is carried out continuously.But in this operating process; because pressure roller is pressed on nip rolls always; when shutting down by inertia effects; the tail end of steel band can be picked out one section; workman is after change of lap; one section of ability to be picked out from next coil band to realize and the welding of a upper coil band, manually steel band be pulled out one section from the roll coil of strip and still require great effort time-consuming.
Summary of the invention
For in prior art, ratio-frequency welded tube in process of production, the steel band used needs when change of lap manually next coil band to be pulled out one section, the problem that could be connected with a upper coil band, the utility model provides a kind of welded tube tendon duct winding machine feed frame steel band suddenly to stop roll-switching device, the feed frame of welded tube tendon duct winding machine is by unwinding rack, deflector roll, nip rolls, pressure roller, change speed gear box, drive motor and storage cassette holder composition, unwinding rack installs steel coil strip, nip rolls installed by the support of unwinding rack rear end, above nip rolls, pressure roller is installed, the rotating shaft of nip rolls is connected with change speed gear box, change speed gear box is connected with drive motor, at the rear side of nip rolls, storage cassette holder is installed, forward (FWD) registration roller is installed in storage cassette holder front end, band registration roller is installed out in rear end, be buffered in storage cassette holder after steel band is bending, at the two ends of pressure roller, compression cylinder is installed, pressure roller is pressed on nip rolls by compression cylinder.
Adopt the technical program, in process of production, when a upper coil band is finished, only need the cylinder using pressure roller two ends, upper pressure-raising roller, make the distress resolves between nip rolls and steel band, namely steel band stops traction, and the tail end of steel band just can stop at reel position immediately, after now workman carries out change of lap, be easy to the welding just carrying out steel band at same position, steel band welding speed is accelerated greatly, and the tape splicing working strength of workman reduces greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Specific embodiments
Embodiment: as shown in Figure 1, a kind of welded tube tendon duct winding machine feed frame steel band is anxious stops roll-switching device, the feed frame of welded tube tendon duct winding machine is by unwinding rack 1, deflector roll 5, nip rolls 6, pressure roller 7, change speed gear box 4, drive motor 3 and storage cassette holder 10 form, unwinding rack 1 is installed steel coil strip 2, nip rolls 6 installed by the support of unwinding rack 1 rear end, pressure roller 7 is installed above nip rolls 6, the rotating shaft of nip rolls 6 is connected with change speed gear box 4, change speed gear box 4 is connected with drive motor 3, at the rear side of nip rolls 6, storage cassette holder 10 is installed, forward (FWD) registration roller 9 is installed in storage cassette holder 10 front end, band registration roller 12 is installed out in rear end, be buffered in storage cassette holder 10 after steel band 11 is bending, at the two ends of pressure roller 7, compression cylinder 8 is installed, pressure roller is pressed on nip rolls 6 by compression cylinder 8.
