The embodiment provides a calendering equipment for stone paper processing, overall structure is as shown in fig. 1-2, includes two at least pairs of running rollers, is equipped with material conveyer belt 2 in front of first pair of running roller 1, sets up edge coiling mechanism in first pair of running roller feeding department.
The edge rolling device is provided with an upper rolling material section 3 and a lower rolling material section 4, the lower rolling material section 4 is connected with the rolling material section 3, the edge of a material layer can be curled inwards and then fed into a gap between rollers of the first pair of rollers, baffle covers 11 are arranged on two sides of the rollers, and the baffle covers 11 and the gap between rollers extrude a discharge space for the purpose.
Wherein, the material conveyer belt 2 adopts a chain plate type conveyer belt, and a bracket is arranged at the lower part. The material conveying belt 2 conveys the material subjected to the co-extrusion process, and the material falls into the coiled material section 3 from the tail end of the chain plate type conveying belt. The material formed by co-extrusion on the material conveying belt is initially molded, the inside of the material conveying belt has cohesive force, the material layer is in a continuous belt shape, the belt-shaped material layer is thicker, and the material conveying belt can bear certain pressure, but the compactness is not uniform.
As shown in fig. 3-5, the rolled material section 3 is formed by deforming a traditional blanking chute, and the whole rolled material section is provided with an inclination angle, so that the material layer can slide downwards. The bottom of the material winding section 3 is a bottom plate 31, the plane of the bottom plate 31 forms a certain included angle with the horizontal plane, and the area gradually decreases from the high position to the low position.
Upper rolling plates 32 are arranged on two sides of the bottom plate 31, the upper end of the bottom plate is in a horizontal direction, and the included angle between the upper rolling plates and the horizontal angle gradually increases downwards along the bottom plate until the bottom end of the bottom plate becomes in a vertical direction. The bottom plate 31 is fixedly installed on a supporting frame, the supporting frame is fixedly installed on a rack, the supporting frame and the rack are arranged according to requirements, and the supporting frame is not shown in the figure.
In practice, the rolled material section 3 may be considered as a flat rolled edge which is inclined, and rolled up from top to bottom with increasing area and angle, until the edges of the two sides of the rolled end are upward.
When a continuous strip material layer enters the upper roll material section 3 from the chain plate type conveyor belt, inward upward acting force is applied by the upper roll plates 32 on two sides of the bottom plate 31, the edge of the strip material layer is rolled up, and then the material layer enters the lower roll material section 4.
The lower roll material section 4 comprises a sliding plate 41 at the bottom, the plane of the sliding plate 41 forms a certain included angle with the horizontal plane, the high end of the sliding plate 41 is connected with the bottom plate 31, and the low end of the sliding plate 41 is adjacent to a roller gap between the first pair of rollers.
In some embodiments, the two sides of the sliding plate are respectively provided with a material pressing plate, the material pressing plates are arranged on the two sides of the sliding plate through supporting rods, and the included angles between the material pressing plates and the vertical direction are sequentially increased along the material flow direction. The edge of the strip-shaped material layer from the material-rolling section can be pressed down from the rolled state, so that the edge of the strip-shaped material layer is in a folded state.
The force of the strip material advancing along the material flow direction comes from the component force of gravity along the material flow direction and the traction force of the first pair of rollers on the strip material, and the friction force of the upper roll material section 3 and the lower roll material section on the strip material layer is resisted. The traction force of the first pair of rollers on the strip-shaped material generally does not change greatly, so that the inclination angle of the edge rolling device needs to be adjusted, the feeding smoothness of the contact surface between the first pair of rollers and the strip-shaped material is ensured, and the strip-shaped material is enabled to smoothly advance.
Compared with the upper coiled material section, the action of coiling down the strip-shaped material layer can generate larger resistance, namely the resistance of the pressing plate in the lower coiled material section is larger than the resistance of the upper coiled material section to the strip-shaped material layer. In order to reduce the smoothness requirement of the edge rolling device, in other embodiments, the roller groups with gradually changed angles can be used for replacing the material pressing plate, so that the resistance to the strip-shaped material layer is reduced, the smoothness requirement is reduced, and the function of the device is easier to realize.
As shown in fig. 2-5, roller sets 42 are respectively arranged on two sides of the sliding plate 41, each roller in the roller sets 42 is installed on two sides of the sliding plate 41 through a supporting rod 43, included angles between axes of rollers in the roller sets 42 and the vertical direction are sequentially increased along the material flow direction, edges of the strip-shaped material layer from the material-rolling section 4 can be pressed down from a rolling state, the edges of the strip-shaped material layer are in a folding state, and then the strip-shaped material layer enters a roller gap between the first pair of rollers.
In the embodiment, three rollers are adopted in the single roller group 42, namely a first roller, a second roller and a third roller from top to bottom, wherein the included angle between the axis of the first roller and the numerical direction is 10 degrees, the included angle between the axis of the second roller and the vertical direction is 45 degrees, and the included angle between the axis of the third roller and the vertical direction is 75 degrees. Because the angle between the roller and the vertical direction gradually becomes larger, namely the included angle between the roller and the horizontal direction gradually becomes smaller, the edge of the strip-shaped material layer is bent from the vertical state to be in a folding state and enters a roller gap between the first pair of rollers.
The overall process of passing the material through the device is described below.
The banded material layer on the material conveying belt 2 falls to the upper roll material section 3, the edge of the banded material layer is gradually rolled up by the upper roll material section 3 to be vertical angle and enters the lower roll material section 4, the edge of the banded material layer which is vertical angle is further pressed down by the lower roll material section 4, the edge of the banded material layer is folded to enter a gap between rollers of the first pair of rollers, rolling and calendaring molding are carried out, the discharged material enters the second pair of rollers 5 to be rolled further, the banded material layer is further thinned, and the compactness is more uniform.
It can be seen that, according to the calendering equipment for stone paper processing provided by the embodiment, as the edges of the strip-shaped material layers are folded before entering the rolling and extending process and then the strip-shaped material layers enter the first pair of rollers for rolling, more materials are filled at the edges, the compactness of the material layers at the edges after calendering is increased, and the cracking of the edges of the stone paper in the subsequent stretching process is reduced.
