Abstract
The utility model relates to a conveying device, in particular to a driven roller used for a coating machine. The driven roller drum comprises a shaft (1) and a drum body (2) sleeved on the shaft (1), wherein a groove (3) is formed on the outer surface of the drum body (2), and comprises a groove section axially formed on the drum body (2), an axial groove section perpendicular to the drum body (2) or an axial groove section oblique to the drum body (2). The surface friction coefficient of the roller is effectively improved, the tension of the materials during the conveying process can be correspondingly increased under the friction force in the rolling direction, and the axial friction force can effectively prevent the materials from deviation.
Description
Technical field
The utility model relates to transmission equipment, is specially the driven voller that a kind of coating machine is used.
Background technology
At present; roller in the application of transmission field and extensively; general roller surface all is smooth; the driven voller that particularly in the wrap-up that coating machine is used, uses; skid easily; also often can be the cloth skew, therefore not make cloth produces needs to increase its appearance in the damaged situation friction coefficient and some anti-offset measures.
The utility model content
The purpose of this utility model provides a kind of surface friction coefficient suitably and can prevent the driven voller of material shifts.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of driven roller, comprise axle and the cylindrical shell that is socketed on the axle, the outside face of cylindrical shell is provided with groove, groove comprise along drum shaft to the groove section or perpendicular to drum shaft to the groove section or favour drum shaft to the groove section.The friction coefficient of appearance can be effectively increased and the skew of material can be prevented.
As to of the present utility model preferred, all grooves on the outside face of cylindrical shell around the cylindrical shell rotating direction on along drum shaft to axial groove section component summation be consistent.Friction coefficient is consistent on the maintenance cylindrical shell rotating direction.
As to of the present utility model preferred, groove is around the sealing line of rabbet joint on the outside face of cylindrical shell, and along drum shaft to being evenly distributed.Retainer shaft is even to friction coefficient.
As to of the present utility model preferred, per two grooves intersect to form a groove group, and the groove group is along described drum shaft to being evenly distributed.The friction coefficient on Effective Raise surface.
As to of the present utility model preferred, groove is S-shaped curve or linear.
As to of the present utility model preferred, groove is the non-closed line of rabbet joint.
As to of the present utility model preferred, the groove depth of groove is 0.1mm-2.5mm, the too high easy infringement material of the degree of depth.
The beneficial effects of the utility model are: the surface friction coefficient of roller effectively is improved, the friction force of rotating direction so that material in course of conveying tension force can correspondingly be improved, and axial friction force can effectively prevent the skew of material.
Description of drawings
Fig. 1 is the perspective view of the utility model embodiment 1.
Among the figure: 1, axle, 2, cylindrical shell, 3, groove, 4, the groove group.
The specific embodiment
Following specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification sheets, but as long as all are subject to the protection of patent law in claim scope of the present utility model.
Embodiment 1, as shown in Figure 1, a kind of driven roller comprises axle 1 and the cylindrical shell 2 that is socketed on the axle 1, the outside face of cylindrical shell 2 is provided with groove 3, and groove 3 comprises along the axial groove section of cylindrical shell 2 or perpendicular to the axial groove section of described cylindrical shell 2 or favour the axial groove section of described cylindrical shell 2.All grooves 3 are being consistent along cylindrical shell 2 axial axial groove section component summations on around cylindrical shell 2 rotating directions on the outside face of cylindrical shell 2.Groove 3 is around the sealing line of rabbet joint on the outside face of cylindrical shell 2, and per two grooves 3 intersect to form a groove group 4, and groove group 4 axially is evenly distributed along described cylindrical shell 2.Groove 3 is S-shaped curve or linear.The groove depth of groove 3 is 0.1mm-2.5mm.
