Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the utility model is described in further detail for embodiment.
As depicted in figs. 1 and 2, the utility model discloses the unwinding device of a kind of band automatic deviation rectifying function, this unwinding device is arranged on the front end of emery cloth banding machine, at the uniform velocity being released by emery cloth. Wherein, described unwinding device comprises emery cloth rack A510, volume saddle bar A520 and emery cloth rack A510 of putting for propping sand yardage roll is in transmission connection and the deviation correcting device A530 that adjusts skew amount. Described deviation correcting device A530 is fixed in frame, moves left and right with emery cloth rack A510. A described volume saddle bar A520 of putting is arranged on emery cloth rack A510, at least arranges two and can rotate relative to emery cloth rack A510. This puts volume saddle bar A520 is slave unit, and emery cloth volume is placed in two and puts on volume saddle bar A520, mainly plays a supportive role.
Preferably, owing to emery cloth volume is heavier, move left and right the frictional force between Shi Yufang volume saddle bar A520 bigger, resistance during in order to reduce mobile, unwinding device in the present embodiment also comprises the first sleeve pipe being arranged on emery cloth volume and putting between volume saddle bar A520, described first casing pipe sleeve is being put on volume saddle bar A520, and than putting, volume saddle bar A520 is short, the two ends of the first sleeve pipe by linear bearings with put volume saddle bar A520 and roll and be connected.Emery cloth volume is placed on the first sleeve pipe, can be twisted in emery cloth by the first sleeve pipe to put and moves left and right flexibly on volume saddle bar A520; In addition, the first sleeve pipe is enclosed within to be put on volume saddle bar A520, mounts and dismounts all very convenient, it is possible to realize dismounting fast.
Concrete, shown in composition graphs 1 and Fig. 3, described deviation correcting device A530 comprises correction motor A531, the deflection correction sensor being arranged on emery cloth its degree of deviation of two-sided measurement, line slideway unit A532 and feed screw nut unit A533. Described correction motor A531, line slideway unit A532 and feed screw nut unit A533 are separately fixed in frame. The unit A532 of line slideway described in the present embodiment is set to two, and wherein, the guide rail of line slideway unit A532 is bolted in frame, and rolls up parallel setting with emery cloth, guide rail be provided with two with emery cloth rack A510 bottom fixing slide block. Between the described feed screw nut unit A533 amount of being arranged on line slideway unit A532, its screw mandrel and guide rail parallel, the bottom of its nut and emery cloth rack A510 is fixed. Described correction motor A531 and feed screw nut unit A533 is in transmission connection, and is electrically connected with deflection correction sensor; Correction motor A531 drives emery cloth rack A510 to move on line slideway unit A532 according to the feedback signal of deflection correction sensor.
Preferably, the motor A531 that rectifies a deviation is set to servomotor, it is to increase the stability of deviation-rectifying system and precisely degree. The skew amount send on emery cloth both sides be measured to correction motor A531, correction motor A531 just controlled throwing bar nut unit A533 feeding to the left or to the right, and then the deviation of correction emery cloth by deflection correction sensor.
Further, emery cloth volume along with release emery cloth more many, its center of gravity is more low, therefore in order to limit emery cloth twist in put volume time can not left and right swing, the unwinding device in the present embodiment also comprise to emery cloth volume centering slip locating device A540. Described emery cloth rack A510 both sides are provided with for the groove A541 that slip locating device A540 slides up and down. Described slip locating device A540 comprises the positioning cylinder being arranged in groove A541. Described positioning cylinder is provided with one piece of dividing plate, and dividing plate is provided with to the circular cone shape preset pieces living the emery cloth volume center of circle. Described positioning cylinder drives preset pieces insertion emery cloth volume to position. Preferably, the present embodiment is provided with two groups of slip locating device A540, lays respectively at the two ends of emery cloth volume, withstands emery cloth volume simultaneously and it is carried out centering location. Emery cloth volume is placed in be put on volume saddle bar A520, slip locating device A540 is in the position of groove A541 in adjustment, starts positioning cylinder, and cone top block supports in emery cloth volume core under the promotion of positioning cylinder, restriction emery cloth twists in the skew put in volume process, reduces the impact on deviation correction mechanism.
Further, when putting volume, affect the tractive force of emery cloth to change within the specific limits so that emery cloth volume is rotated further forward due to inertia effect, causes unwinding tension inconstant, it is unfavorable for follow-up cutting operation. Therefore the present embodiment also comprises that to be arranged on emery cloth volume upper for increasing putting the nip roll A550 rolling up resistance. Described nip roll A550 two ends are stuck in the groove A541 of emery cloth rack A510 both sides. When putting volume, pressure roller is pressed on emery cloth volume, by increasing the frictional force to emery cloth surface, weakens the inertia of emery cloth volume self, reaches the effect that unwinding tension is constant.
The utility model is operationally, only emery cloth volume need to be placed on two puts on volume saddle bar A520, the axle center that emery cloth is rolled up is positioned centering by adjustment locating device A540, finally machine, deviation correcting device A530 on unwinding device just can rectify a deviation automatically, level of automation height, it may also be useful to very convenient.
In sum, the utility model has abandoned the inflatable axle that prior art uses, and adopts two driven saddle bars to hold emery cloth volume, makes material loading and discharging all rapidly very convenient. And, emery cloth rack A510 is arranged on line slideway unit A532, drives emery cloth rack A510 to move left and right by automatic deviation rectifying device A530, for revising the emery cloth deviateing normal path. Solve the technical problem being not easy replacing emery cloth volume, can not automatically correcting deviation emery cloth that existing unwinding device exists well.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills; can be improved according to the above description or be converted; such as; to common/usual replacement etc. of each component in the utility model, all these improve and convert the protection domain that all should belong to the utility model claims.
