Self-clamping and bearing frame for coreless stained paper roll

Abstract

The invention relates to a self-clamping and bearing frame for a coreless stained paper roll. The self-clamping and bearing frame comprises two bearing baseplates respectively arranged at the front and rear sides; each of the bearing baseplates is an isosceles trapezoid plate; a first opening is formed in the upper end surface of each of the bearing baseplates; each first opening is shaped like an isosceles trapezoid; each of the bearing baseplates is vertically placed; the lower side of the middle of the front end surface of the bearing baseplate at the rear side is provided with a baffle plate forwards extending along the longitudinal direction; the upper end surface of the baffle plate is fixedly provided with a spring; the upper end of the spring is connected with a supporting frame; the upper end of the supporting frame is provided with a downward and inward concave arc-shaped supporting surface; and a second opening is formed in the lower end surface of the supporting frame. The supporting frame of the self-clamping and bearing frame is a supporting structure for the coreless stained paper roll, the surrounding range is wide when a cylindrical coreless stained paper roll is supported by the arc-shaped supporting surface, on the other hand, the upward slide of two arc-shaped slide blocks is mechanically triggered by virtue of the pressure of the coreless stained paper roll to the supporting frame, and the two arc-shaped slide blocks are merged, so that the first opening is sealed.

Description

technical field [0001] The invention relates to the technical field of decal storage equipment, in particular to a coreless decal roll self-clamping carrier. Background technique [0002] The storage of decals is usually carried out by rolling. On the one hand, the rolled paper has no creases and does not affect the use. On the other hand, the way of rolling can greatly reduce the space occupied by decals. In order to further compress the occupied space, there is no Core winding should be used more, but coreless winding is easy to cause the decal to bend in the direction perpendicular to the winding axis, and seriously cause the coreless decal to break as a whole. [0003] For the preservation of coreless decals, to prevent the overall bending of coreless decals, and to avoid problems such as decoiling of coreless decals, people need a device with better protection performance to support, store, and store coreless decals. protection and storage.
