Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rock wool production equipment, in particular to a multi-layer rock wool pressing system. BACKGROUND

[0002] The production process of rock wool board is to put basalt slag into a high melting furnace for full melting, then high-speed centrifugal spinning, and then cooling and forming by using a blower, while spraying water-repellent agent, binder and adhesive for shaping. Subsequently, stacking and paving are carried out in a pendulum device, the number of stacked layers is changed according to order requirements to ensure the thickness, then compaction is carried out between rollers to increase the density, and then high-temperature drying is carried out, and cutting can obtain rock wool board.

[0003] In actual production process, since the single-layer thickness of rock wool fiber board is relatively thin, multiple layers need to be stacked to meet order requirements. The fiber direction inside the fiber board is relatively consistent, and the continuity of the fiber in the thickness direction is poor. The connection between the multi-layer boards mainly relies on the adhesive therein, and the overall integrity is poor, which is prone to delamination and other problems. Moreover, for rock wool boards produced in a production line, the edge position has poor flatness and poor density compared to the middle position. In actual processing, most of the edge positions will be cut. A large amount of dust is generated during the cutting process, and a large amount of raw material is wasted. Moreover, the end surface of the cut rock wool board has a large number of fine short fibers, which are extremely easy to peel off. When exposed to the outside, there is a problem of water penetration, which affects the durability of the board as a whole.

[0004] As disclosed in the Chinese patent application No. 202110838228.8, a method for adjusting the strike direction of rock wool fiber by using a piercing needle is disclosed to meet the longitudinal strength of rock wool board and reduce the risk of delamination. However, in this method, an elastic hanging hook is used in the structure of the piercing needle, and an electromagnetic push rod is used to drive reciprocating motion, which has high overall energy consumption, high requirements for the rigidity, toughness and wear resistance of the hanging hook, and high overall production cost. SUMMARY

[0005] The technical problem to be solved by the present application is to overcome the defects of the prior art and provide a multi-layer rock wool pressing system. The longitudinal fiber is stretched by the adjusting part before rock wool pressing, the fiber connection amount between the multi-layer fiber boards is increased, the connection degree between the multi-layer boards is improved, and the delamination phenomenon is avoided. At the same time, the wrapping degree and flatness of the exposed surface are improved by folding the middle layer and wrapping the outer layer in the edge position. The rock wool board can be directly used without cutting, the production process is saved, the production cost is reduced, and the problems in the background art can be effectively solved.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a multi-layer rock wool pressing system, comprising an adjusting part, an edge sealing part and a pressing part.

[0007] The adjusting part comprises two layers of laminating roller groups, and each layer of laminating roller group is alternatively arranged with several groups of adjusting rollers and laminating rollers, and the adjusting rollers in the two layers of laminating roller groups are arranged alternately;

[0008] The adjusting roller comprises an absolutely fixed shaft, an outer light cylinder coaxially rotating relative to the shaft, and an adjusting hook needle rotating along the radial direction of the outer light cylinder and revolving around the shaft, and the shaft and the adjusting hook needle are connected through a bevel gear pair;

[0009] The laminating roller is cylindrical and has the same diameter as the adjusting roller and is arranged in parallel with the adjusting roller.

[0010] The edge sealing part comprises a side edge beating device for beating the side edge of the rock wool board through swinging, and vertical hook needles distributed on the upper and lower sides of the edge and capable of reciprocating longitudinally.

[0011] The beating part of the side edge beating device is a V-shaped structure with the middle layer folded inward, and a plurality of vertical through holes are arranged at the bending position; when the side edge beating device moves to the maximum contact position with the rock wool board, the vertical hook needles can penetrate the two folded surfaces of the side edge beating device through the vertical through holes.

[0012] The laminating part comprises two groups of laminating roller groups arranged above and below, and the diameter and spacing of the laminating roller groups in the laminating part are less than or equal to the diameter and spacing of the laminating roller groups in the adjusting part.

[0013] As a preferred technical solution of the present application, the outer light cylinder surface is arranged with a plurality of through holes in the form of a spiral line, the through holes are provided with mounting caps, and the adjusting hook needle is rotatably mounted with the mounting cap.

[0014] The mounting cap is embedded in the counterbore to ensure the smoothness of the outer light cylinder surface.

[0015] The end part chain wheel is coaxially fixed to the end part of the outer light cylinder, and the shaft is coaxially rotatably mounted with the end part chain wheel.

[0016] During installation, the end part chain wheel is fixedly mounted with the mounting seat and the rack, and the shaft is directly fixed with the mounting seat; when the adjusting roller is driven to rotate, the circumferential surface linear velocity of the outer light cylinder is consistent with the flow line feeding speed, and the adjusting hook needle revolves around the shaft together with the outer light cylinder, and in the revolving process, the sun gear cone is coaxially arranged in the shaft, and the planetary gear is arranged at the end part of the adjusting hook needle, and the two are meshed with each other, that is, the adjusting hook needle revolves while rotating, and when it is inserted into the rock wool layer, it will carry the internal rock wool upward and pass through the multiple rock wool boards to form longitudinal fibers.

[0017] The end part chain wheel is coaxially fixed to the end part of the outer light cylinder, and the end part chain wheels at the ends of the laminating rollers and the adjusting rollers in the same layer are connected with the power source through a chain.

[0018] As a preferred technical solution of the present application, the adjusting hook needle is crescent-shaped or spiral-shaped, and the bottom end of the adjusting hook needle is pointed and provided with a hook;

[0019] Since the adjusting roller and the rock wool board are in a state of continuous relative motion, the use of a straight adjusting hook needle will result in a small insertion angle, which is prone to cause the adjusting hook needle to break. By setting a crescent-shaped or spiral-shaped adjusting hook needle, the insertion angle can be increased to avoid the hook needle from breaking.

[0020] As a preferred technical solution of the present application, the side edge beating is a lever structure, and the middle part is rotationally installed with a vertical rotating shaft, and the free end is provided with a reciprocating rocker mechanism; the vertical hook needle is provided with a reciprocating rocker mechanism that moves up and down, the bottom of the vertical hook needle is pointed and provided with a hook that faces the downstream side; the hook needles on the upper and lower sides are arranged alternately, and the movement speeds are consistent;

[0021] Through the lever structure and the rocker mechanism, the side edge beating continuously beats the side edge of the rock wool board, and by means of the V-shaped structure, the middle layer of the rock wool layer is compressed inward. After compression, the vertical stretching of the rock wool fibers is performed by the two groups of vertically arranged hook needles, and the stretching part is the fiber in the upper or lower rock wool layer, that is, the rock wool fibers on the upper and lower sides of the edge of the rock wool board are interwoven and crossed, thereby achieving the effect of edge covering and improving the wrapping performance of the side edge of the rock wool board.

[0022] As a preferred technical solution of the present application, the input ends of the rocker mechanisms of the side edge beating and the vertical hook needle are connected with the power source through a gearbox, and the reciprocating frequency ratio of the side edge beating and the vertical hook needle is N:1, N≥3;

[0023] By adjusting the reciprocating frequency of the side edge beating and the vertical hook needle, the side of the rock wool board can be fully beaten to ensure the compression amount, and the flatness of the side edge of the rock wool board is ensured due to the limitation of the maximum stroke of beating.

[0024] As a preferred technical solution of the present application, the common tangent plane of the lower compression roller group in the adjusting part is a horizontal plane, the common tangent plane of the upper compression roller group is an inclined plane with an included angle α1 or a multi-stage inclined plane with an included angle gradually decreasing and the included angle of the last stage being α1, 5°≤α1≤30°; the adjusting roller is arranged at the tail end of the inclined plane or the position corresponding to the last stage of the inclined plane;

[0025] The adjusting roller is arranged at the pre-compression stage before complete compression. At this time, the rock wool is relatively fluffy, the activity space of the rock wool fibers is large, the activity is less limited, the fibers are not easy to break during stretching, and longitudinal fiber weaving is easy to perform.

[0026] As a preferred technical scheme of the present application, the diameter and the axial distance of the pressing roller group of the lower layer of the pressing part are smaller than the diameter and the axial distance of the pressing roller group in the adjusting part, and extend into the edge sealing part; the diameter and the axial distance of the pressing roller group of the upper layer of the pressing part are equal to the diameter and the axial distance of the pressing roller group in the adjusting part, and the common tangent plane is an inclined plane with an angle α2, 0°≤α2≤2°.

[0027] Compared with the prior art, the present application has the beneficial effects that: the multi-layer rock wool pressing system uses the adjusting hook needle to longitudinally stretch the fibers in the rock wool board from the upper and lower sides of the rock wool board, increases the amount of longitudinal fibers, thereby avoiding the delamination of the rock wool board, reducing the amount of adhesive in the rock wool board, improving the environmental protection level, and reducing the production cost.

[0028] Meanwhile, the adjusting hook needle adopts a structure design of revolution and rotation of the adjusting roller, and combines with the crescent or spiral structure design of the adjusting hook needle, improves the needle entry angle, reduces the deformation amount when entering the needle, reduces the toughness requirement of the hook needle and the wear amount of the hook needle, prolongs the service life of the hook needle, reduces the production cost, and at the same time, since the adjusting hook needle rotates itself when entering and exiting the needle, the fibers hooked by the adjusting hook needle and the fibers of the corresponding layer are entangled, improving the integrity of the rock wool fibers of different layers.

[0029] Meanwhile, the edge sealing part is used for edge sealing, the V-shaped side is struck, the V-shaped wrinkles are discharged from the side, and the fibers of the upper and lower layers of rock wool are stretched and woven by the vertical hook needle, so that the effect of wrapping the side edge is formed after subsequent pressing, the flatness of the side edge is ensured without cutting the side edge, the waste of raw materials is reduced, and the output rate is improved.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0045] Please refer to Figure 1 and Figure 2 , the present application provides a technical solution: a multi-layer rock wool pressing system, comprising an adjusting part 1, an edge sealing part 2 and a pressing part 3;

[0046] The adjusting part 1 comprises two layers of laminating roller groups, and each layer of laminating roller group is alternately arranged with a plurality of groups of adjusting rollers and laminating rollers, and the adjusting rollers in the upper and lower laminating roller groups are arranged alternately;

[0047] The adjusting roller comprises an absolutely fixed mandrel 1012, an outer light cylinder coaxially rotating relative to the mandrel 1012, an adjusting hook needle 1011 rotating along the outer light cylinder and revolving around the mandrel 1012, and the mandrel 1012 and the adjusting hook needle 1011 are connected through a bevel gear pair;

[0048] The laminating roller is equal in diameter to the adjusting roller and is arranged in parallel, in a cylindrical shape;

[0049] The edge sealing part 2 comprises a side edge beating 201 for beating the side edges of the rock wool board by swinging, and vertical hook needles 202 arranged on both sides of the edge and capable of reciprocating longitudinally;

[0050] The beating part of the side edge beating 201 is a V-shaped structure with the middle layer folded inward, and a plurality of vertical through holes are arranged at the bending position; when the side edge beating 201 moves to the maximum contact position with the rock wool board, the vertical hook needles 202 can penetrate the two folded surfaces of the side edge beating 201 through the vertical through holes;

[0051] The pressing part 3 comprises two groups of pressing roller sets arranged above and below, and the diameters and spacings of the pressing roller sets in the pressing part 3 are less than or equal to the diameters and spacings of the pressing rollers in the adjusting part 1.

[0052] Referring to Figure 1 and Figure 3 , a plurality of groups of through holes are arranged in a spiral line on the surface of the outer light cylinder, and a mounting cap 1014 is arranged in the through hole, and the adjusting hook needle 1011 is rotatably mounted with the mounting cap 1014;

[0053] The adjusting hook needle 1011 is arranged in a spiral line on the outside of the outer light cylinder, that is, in the same transverse section, the adjacent two groups of adjusting hook needles 1011 have a large needle insertion distance, which ensures that when the fibers are hooked, the internal fiber void volume will not be too large, and the stability of the original transverse fibers of the rock wool board is maintained.

[0054] The mounting cap 1014 facilitates the disassembly and replacement of the adjusting hook needle 1011, and improves the overall wake convenience, and preferably the through hole is a counterbore, and the mounting cap 1014 can be embedded in the counterbore to ensure the smoothness of the surface of the outer light cylinder;

[0055] The end portion chain wheel 1015 is coaxially fixedly arranged at the end portion of the outer light cylinder, and the mandrel 1012 is rotatably mounted coaxially with the end portion chain wheel 1015;

[0056] During installation, the end portion chain wheel 1015 is fixedly mounted with the mounting seat 1016 and the rack, and the mandrel 1012 is directly fixed with the mounting seat 1016, when the first adjusting roller 101 is driven to rotate, the circumferential surface linear velocity of the outer light cylinder is consistent with the flow line feeding speed, and the adjusting hook needle 1011 revolves around the mandrel 1012 together with the outer light cylinder, and in the revolution process, the sun gear cone is coaxially arranged in the mandrel 1012, and the planetary cone is arranged at the end portion of the adjusting hook needle 1011, the two are meshed with each other, that is, the adjusting hook needle 1011 revolves while rotating, when it is inserted into the rock wool layer, it will lift the internal rock wool upward, pass through multiple layers of rock wool board, and form longitudinal fibers.

[0057] The end portion chain wheel 1015 is coaxially fixed at the end portion of the covering roller, and the end portion chain wheels 1015 at the end portions of the covering rollers and the adjusting rollers of the same layer are connected with the power source through a chain.

[0058] Referring to Figures 4-8 , the adjusting hook needle 1011 is crescent or spiral shaped, the bottom end of the adjusting hook needle 1011 is pointed and provided with a hook;

[0059] Since the adjusting roller and the rock wool board are in a state of continuous relative motion, the use of a straight adjusting hook needle 1011 will make the insertion angle small, which is easy to cause the adjusting hook needle 1011 to break. By setting the crescent or spiral shaped adjusting hook needle 1011, the insertion angle can be increased to avoid the hook needle from breaking.

[0060] Referring to Figure 5 and Figure 6 When the crescent shaped adjusting hook needle is used, the bottom needle tip insertion angle should be between 80°-100° to reduce the needle insertion resistance. The root of the adjusting hook needle 1011 is consistent with the speed of the rock wool, and the needle tip part has a speed greater than the rock wool speed. When the hook lifts the longitudinal motion, the fibers will first move forward and backward, that is, the longitudinal limit will drive the transverse fibers of different layers at the corresponding position to cross. When the rock wool board is longitudinally torn, the friction between the longitudinal fibers and the transverse fibers can be further increased, thereby improving the integrity of the overall board.

[0061] At the same time, multiple groups of hooks can be set at different heights of the adjusting hook needle 1011. After the adjusting hook needle is inserted, the rock wool fibers at different thicknesses can be simultaneously lifted longitudinally, causing mutual entanglement between fibers at different layers, further increasing the friction between longitudinal fibers and transverse fibers.

[0062] The included angle between the adjusting hook needle 1011 insertion and extraction positions is β, 60°≤β≤120°, and the self-rotation angle of the adjusting hook needle 1011 from the insertion to the extraction is 180°. Taking β=90° as an example, the adjusting hook needle 1011 rotates 2 times itself for every revolution. The transmission ratio of the bevel gear pair 1013 is determined in this way, and the line connecting the insertion point and the extraction point is tangent to the outer circumferential surface of the outer light cylinder, thereby determining the length and curvature of the adjusting hook needle 1011.

[0063] Referring to Figure 7 and Figure 8 The self-rotation angle of the adjusting hook needle 1011 after insertion can be freely designed when the spiral shaped adjusting hook needle 1011 is used, and only needs to ensure that the line connecting the insertion point and the extraction point is tangent to the outer circumferential surface of the outer light cylinder. During the pressing, the hook at the needle tip position drives the fibers to move in a spiral motion. Since the hook opening is large, the fibers hooked in the early stage are separated from the hook after being entangled with the upper layer of transverse limit, and the subsequent transverse fibers are hooked again to become longitudinal fibers and are entangled with the upper layer of transverse fibers again, thereby forming discontinuous longitudinal entangled fiber sections in different thickness layers in the rock wool board, reducing the longitudinal displacement of a single group of fibers, and reducing the probability of fiber breakage during pulling.

[0064] Referring to Figures 9-12 , the side beating 201 is a lever structure, and the middle part is rotationally installed with a vertical rotating shaft, and the free end is provided with a reciprocating rocker mechanism; the vertical hook needle 202 is provided with a reciprocating rocker mechanism inside, the bottom of the vertical hook needle 202 is conical and provided with a hook towards the downstream side; the two hook needles on the upper and lower sides are staggered and have consistent movement speed;

[0065] Referring to Figure 13 , through the lever structure and the rocker mechanism, the side beating 201 drives the continuous beating of the side edge of the rock wool board, and by means of the V-shaped structure, the middle layer of the rock wool layer is compressed inward, and after compression, the vertical stretching of the rock wool fiber is performed by the two groups of vertical hook needles 202 arranged alternately, that is, the rock wool fibers on the upper and lower sides of the edge of the rock wool board are interwoven and crossed, thereby achieving the effect of edge covering and improving the wrapping performance of the side edge of the rock wool board.

[0066] The input end of the rocker mechanism of the side beating 201 and the vertical hook needle 202 is connected with the power source through a gearbox, and the reciprocating frequency ratio of the side beating 201 and the vertical hook needle 202 is N:1, N≥3;

[0067] When the proportion is set, it can be set according to the line speed of the assembly line. If the line speed is slow, the N value can be increased to increase the beating frequency and reduce the piercing frequency to avoid the problem of fiber breakage caused by excessive piercing;

[0068] On the contrary, if the line speed is fast, the beating frequency is maintained and the piercing frequency is increased to ensure that the side edge is not missed and the side edge wrapping rate is improved.

[0069] By adjusting the reciprocating frequency of the side beating 201 and the vertical hook needle 202, the side of the rock wool board can be fully beaten to ensure the compression amount, and the flatness of the side edge of the rock wool board is ensured due to the limitation of the maximum beating stroke.

[0070] Referring to Figure 2 , the common tangent surface of the lower layer of the pressing roller group in the adjusting part 1 is a horizontal plane, the common tangent surface of the upper layer of the pressing roller group is an inclined plane with an included angle α1 or a multi-stage inclined plane with an included angle gradually decreasing and the last stage included angle α1, 5°≤α1≤30°; the adjusting roller is arranged at the tail end of the inclined plane or the position corresponding to the last stage inclined plane;

[0071] The adjusting roller is arranged in the pre-pressing stage before complete pressing, at this time the rock wool is relatively fluffy, the activity space of the rock wool fiber is large, the activity is less limited, and it is not easy to break during stretching, and it is easy to weave the longitudinal fibers.

[0072] Referring to Figure 2, set time, for example, two sets of adjusting roller, the first adjusting roller 101, the first laminating roller 102, the second adjusting roller 104, the second laminating roller 103, from left to right in turn around the anticlockwise direction arrangement, and the first adjusting roller 101 and the first laminating roller 102 in the longitudinal projection overlap, the second laminating roller 103 and the second adjusting roller 104 in the longitudinal projection overlap, and at this time, alpha 1=6°, the gap between the upper laminating roller group and the lower laminating roller group gradually decreases, showing a compression trend, at this time, the rock wool layer is relatively soft, and the rock wool fiber has a large activity allowance, at this time, the adjusting hook needle 1011 in the adjusting roller is not easy to break the fiber when acting on the rock wool fiber, which can effectively ensure the length of the internal fiber.

[0073] Referring to Figure 2 , the diameter and the shaft spacing of the laminating roller group of the lower layer of the laminating part 3 are smaller than the diameter and the shaft spacing of the laminating roller group in the adjusting part 1, and extend into the edge sealing part 2; the diameter and the shaft spacing of the laminating roller group of the upper layer of the laminating part 3 are equal to the diameter and the shaft spacing of the laminating roller group in the adjusting part 1, and the common tangent plane is an inclined plane with an included angle of alpha 2, 0°≤alpha 2≤2°;

[0074] In the laminating part 3, the laminating roller group of the lower layer adopts a small-diameter laminating roller, which increases the supporting area and reduces the interval between the supporting points, thereby ensuring the flatness of the bottom.

[0075] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
