Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a commodity or system that includes the element.
Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.
The calendering equipment for stone paper processing that this embodiment provided, overall structure is as shown in fig. 1-2, includes two at least pairs of running rollers, is equipped with material transmission band 2 before first pair of running roller 1, sets up marginal coiling material device 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 an incoming material layer can be curled inwards and then sent into the gap between the 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 the rollers extrude a discharging space.
Wherein, material transmission band 2 adopts the chain slat type conveyer belt, and the lower part sets up the support. The material conveying belt 2 conveys materials finished by the co-extrusion process, and the materials fall from the tail end of the chain plate type conveying belt to enter the upper roll material section 3. The material that co-extrusion was accomplished on the material transmission area has tentatively shaped, and inside has the adhesion stress, and the bed of material is continuous banding, and the belt bed of material is thicker, can bear certain pressure, but closely knit degree is not very even.
As shown in fig. 3-5, the upper roll material section 3 is formed by deforming a conventional blanking scraper-trough conveyer, and has an inclination angle as a whole, which is beneficial to the downward sliding of the material layer. The bottom of the upper roll material section 3 is a bottom plate 31, a plane where the bottom plate 31 is located and a horizontal plane form a certain included angle, and the area is gradually reduced from a high position to a low position.
The board 32 of rolling up is set up to the both sides of bottom plate 31, is the horizontal direction at the high-end of bottom plate, and along the bottom plate downwards with horizontal included angle grow gradually, become vertical direction until the bottom of bottom plate. On bottom plate 31 fixed mounting support frame, support frame fixed mounting in the frame, the support frame with the frame set up as required can, not shown in the figure.
In fact, the rolled material section 3 can be regarded as a flat rolled edge which is obliquely arranged, the area of the rolled material section from top to bottom is more and more, and the angle is larger and larger until the two side edges of the rolled material section are upward.
When a continuous strip of material is fed from the chain conveyor into the upper roll section 3, it is forced inwardly and upwardly by the upper rolls 32 on either side of the base plate 31 to roll up the edges of the strip and the material then passes into the lower roll section 4.
The down-rolling 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 the roller gap between the first pair of rollers.
In some embodiments, the two sides of the sliding plate are respectively provided with a pressure plate, the pressure plates are arranged on the two sides of the sliding plate through support rods, and included angles between the pressure plates and the vertical direction are sequentially increased along the material flow direction. The strip material layer edge that can come down the roll material section is pushed down from the roll-up state, makes strip material layer edge be fold condition.
The power of the strip-shaped material advancing along the material flow direction comes from the component force of the gravity along the material flow direction and the traction force of the first pair of rollers to the strip-shaped material, and the resistance force comes from the friction force of the upper roll material section 3 and the lower roll material section to the strip-shaped material layer. 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 smooth feeding of the contact surface of the first pair of rollers and the strip-shaped material is ensured, and the strip-shaped material can smoothly advance.
Compared with the upper roll material section, the action of rolling down the strip material layer can generate larger resistance, namely the resistance of a material pressing plate in the lower roll material section is larger than the resistance of an upper roll plate of the upper roll material section to the strip material layer. In order to reduce the requirement on the smoothness of the edge rolling device, in other embodiments, a pressure plate can be replaced by a roller set with a gradually changed angle, so that the resistance to the strip material layer is reduced, the requirement on the smoothness is reduced, and the function of the device is easier to realize.
As shown in fig. 2 to 5, roller sets 42 are respectively disposed 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 support rod 43, and included angles between axes of the rollers in the roller sets 42 and a vertical direction are sequentially increased along a material flow direction, so that edges of the strip material layer coming from the lower roll material section 4 can be pressed down from a rolled state, the edges of the strip material layer are folded, and then enter a roller gap between a first pair of rollers.
In the embodiment, a single roller set 42 adopts three rollers, which are respectively 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 of roller and vertical direction grow gradually, promptly with the horizontal direction contained angle diminish gradually, become the running roller clearance between fold condition entering first pair of running roller with banding bed of material edge by vertical state bending.
The overall process of the material through the apparatus is described below.
The strip material layer on the material transmission band 2 falls to and rolls up material section 3, it rolls up the edge of strip material layer gradually and is vertical angle entering coil down material section 4 to roll up material section 3, coil down material section 4 will be the strip material layer edge of vertical angle and further push down, the edge of strip material layer is the roll clearance that the rugosity got into first pair of running roller, roll-in calendering shaping carries out, the ejection of compact reentrants second pair of running roller 5 further calendering, the further attenuation of strip material layer, closely knit degree is more even.
It can be seen that, the calendering equipment for stone paper processing provided by the embodiment folds the strip material layer edge before entering the first pair of rollers for rolling, so that more materials are filled at the edge, the material layer compactness at the calendered edge is increased, and the cracking of the edge position of stone paper in the subsequent stretching process is reduced.
