Abstract
The utility model discloses a kind of strap tension feedway, comprise the outlet roller exporting strap, described strap is successively through the first drive roller sets, doctor roll group, second drive roller sets, described first drive roller sets comprises two driven rollers be close to up and down being driven stopping by motor or rotated, described second drive roller sets comprises two driven rollers be close to up and down being driven stopping by motor or rotated, described doctor roll group comprises two stationary rolls be arranged in parallel, a dancer roll be arranged between described two stationary rolls, described dancer roll two ends are arranged in vertical guide rail and an end is protruding stop part, the up-and-down movement track of described stop part is provided with two pairs of laser switches, quantitatively export because the utility model adopts dancer roll to coordinate with stationary roll, the strap length exported is stablized.
Description
Technical field
the utility model relates to a kind of strap tension feedway.
Background technology
the interrupted output of one section of one section of regular length of regular length is needed time strap uses when waterproof roll packaging, then present strap exports and generally adopts stepping motor, but because the tensioning degree of strap is unstable, the strap causing output is also different in size, cannot stablize output.
Summary of the invention
the purpose of this utility model is to provide a kind of strap tension feedway of stable output.
for achieving the above object, the technical solution adopted in the utility model is:
a kind of strap tension feedway, comprise the outlet roller exporting strap, described strap is successively through the first drive roller sets, doctor roll group, second drive roller sets, described first drive roller sets comprises two driven rollers be close to up and down being driven stopping by motor or rotated, described second drive roller sets comprises two driven rollers be close to up and down being driven stopping by motor or rotated, described doctor roll group comprises two stationary rolls be arranged in parallel, a dancer roll be arranged between described two stationary rolls, described dancer roll two ends are arranged in vertical guide rail and an end is protruding stop part, the up-and-down movement track of described stop part is provided with two pairs of laser switches.
the diameter specifically equaling dancer roll between described two stationary rolls.
the top of described outlet roller is provided with belt fixed frame, and described belt fixedly adds the belt hanging with weight that hangs down.
because technique scheme is used, the utility model compared with prior art has following advantages:
quantitatively export because the utility model adopts dancer roll to coordinate with stationary roll, make the strap length of output stable.
Accompanying drawing explanation
accompanying drawing 1 is schematic diagram of the present utility model.
in above accompanying drawing: 1, outlet roller; 2, the first drive roller sets; 3, the second drive roller sets; 4, stationary roll; 5, dancer roll; 6, guide rail; 7, stop part; 8, laser switch; 9, belt fixed frame; 10, weight; 11, belt.
Detailed description of the invention
below in conjunction with embodiment shown in the drawings, the utility model is further described:
embodiment one: shown in accompanying drawing 1, a kind of strap tension feedway, comprise the outlet roller 1 exporting strap, strap is successively through the first drive roller sets 2, doctor roll group, second drive roller sets 3, first drive roller sets 2 comprises two driven rollers be close to up and down being driven stopping by motor or rotated, second drive roller sets 3 comprises two driven rollers be close to up and down being driven stopping by motor or rotated, doctor roll group comprises two stationary rolls be arranged in parallel 4, a dancer roll 5 be arranged between two stationary rolls 4, dancer roll 5 two ends are arranged in vertical guide rail 6 and an end is protruding stop part 7, the up-and-down movement track of stop part is vertically disposed with as required two pairs of laser switches 8.
the diameter specifically equaling dancer roll 5 between two stationary rolls 4.
the top of outlet roller 1 is provided with belt fixed frame 9, and belt fixedly adds the belt 11 hanging with weight 10 that hangs down.
during the present embodiment work: the second drive roller sets 3 stops, first drive roller sets 2 drives, strap is exported, and, dancer roll 5 promotes along guide rail 6, when the stop part 7 of dancer roll 5 blocks the laser switch 8 on top, first drive roller sets 3 stops, and the second drive roller sets 2 drives, and strap stops exporting, and dancer roll 5 is declined along guide rail 6, when the stop part 7 of dancer roll 5 blocks the laser switch 8 of bottom, the second drive roller sets 3 stops, and the first drive roller sets 2 drives, strap is exported, completes a cycle of operations circulation.
the package length that the present embodiment once exports is the twice of the distance between upper and lower two laser switches 8, working stability.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
