In the prior art, the device of a computational length is often individually set on rewinding machine to realize length gauge Amount increases cost and causes device structure complicated.And in rewinding machine often be equipped with multigroup guide wheel realize line steering, The functions such as tension force, it is therefore necessary to length is realized on the basis of designing a kind of length metering device on guide wheel in above-mentioned function Degree metering.

Invention content

Problem to be solved in the utility model is to provide a kind of guiding wheel assembly with length metering device, by drawing The turnning circle of the mating shaft of guide wheel measures and is converted into electric signal to controller, and controller is according to detected electricity Signal calculates length, realizes the metering of length.

In order to solve the above technical problems, the technical solution adopted in the utility model is：It is a kind of with length metering device It guides wheel assembly, including shaft of the rotary spacing in mounting bracket and guide wheel in described shaft one end is set, it is special Sign is：Further include length metering device, the length metering device include be located at the shaft other end detection piece and Be arranged in the mounting bracket match with the detection piece close to switch.

Further, the detection piece is sleeved on the end of the shaft and is connected with the shaft by bolt, along institute The circumferential direction for stating detection piece is at least uniformly provided with two boss radially extended along the shaft.

Further, the close switch is LR18XBF05DPO.

Further, described to be connected close to switch with the mounting bracket by connecting bracket, it is described to be located at close to switch Above detection piece.

Further, the guide wheel is limited by key connection is radial in the shaft, in the end of the guide wheel Equipped with limit end cap, the limit end cap is connected by connection bolt with the shaft.

Further, bearing holder (housing, cover) is provided in the mounting bracket, the shaft passes through the bearing holder (housing, cover) and in institute It states shaft and bearing inner room is equipped with bearing.

Further, there are two the bearing settings.

Further, the bearing is deep groove ball bearing.

Further, positioning sleeve is equipped between the guide wheel and the inner ring of bearing.

The advantageous effects of the utility model are：By being measured close to switch to detection piece and by obtained letter Number it is transferred to mating controller, controller can calculate length by the rotation situation of guide wheel, realize the metering of length.

The utility model is described in detail below in conjunction with the accompanying drawings.

Description of the drawings

Fig. 1 is the structural schematic diagram of guiding wheel assembly of the utility model with length metering device；

Fig. 2 is Fig. 1 removal mounting brackets and the stereoscopic schematic diagram close to after switching.

In the accompanying drawings：1 is mounting bracket, and 2 be shaft, and 3 be guide wheel, and 4 be detection piece, and 4-1 is boss, and 5 be close open It closes, 6 be connecting bracket, and 7 be limit end cap, and 8 be bearing holder (housing, cover), and 9 be bearing, and 10 be positioning sleeve, and 11 be end cap.

Specific implementation mode

Referring to attached Fig. 1 and 2, the utility model provides a kind of guiding wheel assembly with length metering device, including turns Dynamic to limit the shaft 2 in mounting bracket 1 and the guide wheel 3 in 2 one end of shaft is arranged, key is：It further include length gauge Measure device, length metering device include be located at the detection piece 4 of 2 other end of shaft and be arranged in mounting bracket 1 with detection Part 4 match close to switch 5.

Above-mentioned detection piece 4 is sleeved on the end of shaft 2 and is connected with shaft 2 by bolt, along detection piece 4 circumferential direction extremely It is uniformly provided with two boss 4-1 radially extended along shaft 2 less.There are two boss 4-1 settings in the present embodiment, when shaft 2 Two boss 4-1, which can make to approach switch 5, when rotating a circle break-make twice, and mating controller is then according to leading to close to switch 5 Power-off signal judges that shaft 2 has rotated one week and calculate the length of outlet movement, then when the electric signal detected is odd number Assert that there are one half-turns in the number of turns that shaft 2 rotates.It is readily apparent that boss 4-1 be arranged more at most length computation essence Degree is more accurate.

Above-mentioned uses LR18XBF05DPO close to switch 5.Close to switch 5 by connecting bracket 6 and 1 phase of mounting bracket Even, it is located at 4 top of detection piece close to switch 5.

In shaft 2, limit end cap is equipped in the end of guide wheel 3 by the radial limit of key connection for above-mentioned guide wheel 3 7, limit end cap 7 is connected by connection bolt with shaft 2.

Bearing holder (housing, cover) 8 is provided in mounting bracket 1, shaft 2 passes through bearing holder (housing, cover) 8 and is equipped between shaft 2 and bearing holder (housing, cover) 8 Bearing 9.The outside of bearing holder (housing, cover) 8 is equipped with boss flange, and bearing holder (housing, cover) 8 is connected by flange connection with mounting bracket 1.In bearing The bearing indentation end of set 8 is equipped with the end cap 11 for positioning bearing 9.Positioning sleeve is equipped between guide wheel 3 and the inner ring of bearing 9 10.There are two the settings of bearing 9 and preferred deep groove ball bearing.

It is arranged on rewinding machine when the guiding wheel assembly specific implementation of the utility model, the tenslator on rewinding machine Certain power can be applied to line makes line that guide wheel 3 be driven to rotate.The mating shaft 2 of guide wheel 3 rotates so that detection piece 4 On boss 4-1 close proximity to switch 5 when close to switch 5 generate break-make, the controller detection of rewinding machine approaches the break-make of switch 5 It generates the number of electric signal and is counted.Since the outer diameter of guide wheel 3 it is known that be by detecting the number of turns that guide wheel 3 rotates The length of take-up end take-up can be calculated in real time（It is calculated as having rotated one week twice per break-make close to switch 5）.

Finally it should be noted that：The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still It can modify to the specific implementation mode of the present invention or equivalent replacement is carried out to some technical characteristics；Without departing from this hair The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
