Abstract
The utility model discloses an anti-deviating and anti-edge-loosening drum. The anti-deviating and anti-edge-loosening drum comprises a drum body, and a center shaft which is positioned in the drum body and extended out of the two ends of the drum body, wherein the drum body consists of a left conical part at a left section, a cylindrical part at a middle section, and a right conical part at a right section; the left conical part has a conical structure of which the left part is smaller while the right part is larger; the right conical part has a conical structure of which the right part is smaller while the left part is larger; and the maximum outer diameter of the left conical part, the maximum outer diameter of the right conical part and the outer diameter of the cylindrical part are equal. When a conveying steel belt running in a way of being wound on the drum is deviated, a single-side axle seat of the drum is adjusted to move forwards and backwards to change the tension force and stress on both sides of the conveying steel belt, but a stressed part occurs on the middle part of the conveying steel belt instead of the side edge of the conveying steel belt, so that a deviation adjusting effect is achieved without causing side edge stress of the conveying steel belt, and the beading is avoided. After improvements are made on the anti-deviating and anti-edge-loosening drum, the using effect is improved, and the service life of the conveying steel belt is prolonged.
Description
Technical field
The utility model relates to a kind of roller, is specifically related to a kind of anti-deviation anti-slack list roller.
Background technology
At present, being used for the tensioner tuningout roller that the continuous press of extrusion chipboard generally uses is columniform roller, when transmitting steel band generation sideslip, by moving forward and backward of the one-sided axle bed of roller, make stressed the changing of degree of tightness of transmitting the steel band both sides, the sideslip adjustment that realizes transmitting steel band.But this tuningout form can make two limits of transmitting steel band owing to supportting to rise frequently, elastic failure occur, the bell mouth shape that the distortion that makes the transmission steel band become dual-side forms greater than the middle part, make the transmission steel band be more prone to sideslip, so repeatedly adjust, the exit skirt that transmits steel band is enlarged more, scrap until transmit the steel band inefficacy.
The utility model content
The utility model provides a kind of guarantee to transmit steel band maintenance favorable elasticity and indeformable anti-deviation anti-slack list roller in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: anti-deviation anti-slack list roller, comprise cylindrical shell and be positioned at cylindrical shell and stretch out the center shaft at cylindrical shell two ends, described cylindrical shell is grouped into by the left conical portion of left section, the cylindrical part in stage casing and the right conical portion of right section, left tapered segment is conical structure left small and right large, right conical portion is divided into the large conical structure in a right little left side, and the external diameter of the maximum outside diameter of left tapered segment, the maximum outside diameter of right tapered segment and cylindrical part equates.
adopt technique scheme, the utility model is intermediate drum (slightly), the dolioform structure that two is slightly thin, transmit steel strip winding when cylindrical shell turns round, when if sideslip occurs, adjust moving forward and backward of the one-sided axle bed of roller, make tensioner and stressed the changing of transmitting the steel band both sides, but its force part occurs in the middle part of transmitting steel band, and not on the side that transmits steel band, the beading phenomenon occurs thereby the side that also can not make the transmission steel band when playing the tuningout effect is stressed, therefore improvement of the present utility model has not only improved result of use but also has extended the service life of transmitting steel band.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, anti-deviation anti-slack list of the present utility model roller, comprise cylindrical shell and be positioned at cylindrical shell and stretch out the center shaft 1 at cylindrical shell two ends, cylindrical shell is comprised of the left conical portion 2 of left section, the cylindrical part 3 in stage casing and the right conical portion 4 of right section, left tapered segment 2 is conical structure left small and right large, right conical portion 4 is the large conical structure in a right little left side, and the maximum outside diameter footpath of the maximum outside diameter of left tapered segment 2, right tapered segment 4 and the external diameter of cylindrical part 3 equate.
The utility model is intermediate drum (slightly), the dolioform structure that two is slightly thin, transmit steel strip winding on cylindrical shell during normal operation, transmitting steel band contacts with cylindrical part 3, when if sideslip occurs, adjust moving forward and backward of the one-sided axle bed of roller, make tensioner and stressed the changing of transmitting the steel band both sides, but its force part occurs in the middle part of transmitting steel band, and not on the side that transmits steel band, time of run is of a specified duration, transmits the part that coordinates with cylindrical part 3 in the middle part of steel band and just caves inward, and more and more has been not easy sideslip.Thereby the side that also can not make the transmission steel band when playing the tuningout effect is stressed, the beading phenomenon occurs, therefore improvement of the present utility model has not only improved result of use but also has extended the service life of transmitting steel band.
