[0001] The invention relates to the field of mineral wool processing, and in particular to a processing device for mineral wool strips. Background Art

[0002] As the country attaches great importance to energy conservation and environmental protection, mineral wool, a veteran in thermal insulation, is playing a major role in new industries. In the hot building thermal insulation, the application of mineral wool is also very popular, especially in recent years, fires in the thermal insulation mode of polystyrene foam board have occurred from time to time, and the building thermal insulation industry has always attached great importance to the selection of thermal insulation materials. Mineral wool is increasingly used in the building thermal insulation industry because of its good thermal insulation effect and good non-flammability.

[0003] In the production process of mineral wool strips, during the cotton-forming process of ore, the ore is blown and pulled into fibers. In the process of pressing the fibers into boards, it is found that the density distribution of the mineral wool fibers is uneven during the feeding process of the mineral wool fibers, and there is also a situation where there is less mineral wool material in some areas, resulting in insufficient thickness, thus affecting the quality of the mineral wool board. The density and distribution of the mineral wool fiber material cannot be controlled during the feeding process, thus affecting the subsequent strip cutting process. Part of the mineral wool will also adhere to the conveyor belt for feeding, affecting the subsequent feeding. Summary of the invention

A plurality of through holes are opened on the two groups of flat plates, and the inner diameter of each through hole is slidably connected to a top column, and each group of top columns is perpendicular to the flat plate on which it is located;

[0008] The swing frame is provided with an ejection mechanism, which is located between the two groups of flat plates. The ejection mechanism can control the ejector column to perform reciprocating motion in the inner diameter of the through hole.

[0010] Preferably, a horizontal rotating rod is rotatably connected inside the mounting frame, and a first thread and a second thread are respectively provided at both ends of the rotating rod, and the threads of the first thread and the second thread are in opposite directions. The two ends of the rotating rod are respectively threadedly connected to the two groups of the movable frames through the first thread and the second thread, and the rotating rod is rotated to change the spacing between the two groups of the movable frames.

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] Embodiment 1:

[0039] like Figure 1-2 The processing equipment of mineral wool strips shown in the figure comprises a swing frame 1 and a cotton pressing conveyor belt 8. The swing frame 1 is a rectangular frame and is placed vertically. A shaft is arranged on the top of the swing frame 1. The swing frame 1 swings back and forth above the cotton pressing conveyor belt 8 at the midpoint of the shaft.

[0040] In the prior art, two sets of conveyor belts are installed on the swing frame 1. The mineral wool fibers are conveyed downward between the gaps between the two sets of conveyor belts and fall on the cotton pressing conveyor belt 8. The swing frame 1 swings back and forth on the cotton pressing conveyor belt 8 to lay the mineral wool fibers layer by layer on the cotton pressing conveyor belt 8.

[0041] It also includes a spacing adjustment mechanism 2, which is installed on the swing frame 1, and a material discharge conveyor belt 4 is installed on both sides of the swing frame 1. The two groups of material discharge conveyor belts 4 are parallel to each other and are respectively located on both sides of the swing frame 1;

[0042] Flat plates 101 are installed on both sides of the swing frame 1. The two groups of flat plates 101 are parallel to the two groups of unloading conveyor belts 4. A plurality of through holes 102 are opened on the two groups of flat plates 101. The inner diameter of each through hole 102 is slidably connected to a top column 6. Each group of top columns 6 is perpendicular to the flat plate 101 on which it is located.

[0043] Different from the prior art, the mineral wool fibers of the present application are no longer transported downward through the gap between the two conveyor belts, but are transported through the gap between the two sets of unloading conveyor belts 4 and the corresponding flat plates 101. The driving member drives the unloading conveyor belts 4 to operate, and the original one unloading channel is changed into two parallel unloading channels.

[0044] The position of the flat plate 101 is fixed, and the spacing between the two groups of unloading conveyor belts 4 is changed by the spacing adjustment mechanism 2, thereby changing the gap between the unloading conveyor belt 4 and the corresponding flat plate 101, so as to control the amount of mineral wool fiber unloading.

[0045] The swing frame 1 has an ejection mechanism 5 therein, and the ejection mechanism 5 is located between the two groups of the flat plates 101 . The ejection mechanism 5 can control the ejection column 6 to perform reciprocating motion in the inner diameter of the through hole 102 .

[0046] When the mineral wool is conveyed downward in the gap between the unloading conveyor belt 4 and the flat plate 101, in order to prevent the density distribution of the mineral wool fibers from being uneven, resulting in the situation that some parts are too thick and some parts are very loose, the present application drives the top column 6 on the flat plate 101 to make reciprocating motion through the ejection mechanism 5. The top column 6 is intermittently inserted into the mineral wool fibers, which can loosen the mineral wool in the gap. If the laid mineral wool is too thick, the top column 6 will press it to the edge. The intermittent reciprocating motion of multiple top columns 6 can make the mineral wool evenly distributed between the gap between the unloading conveyor belt 4 and the flat plate 101 during the conveying process.

[0047] Since there are two material discharge channels, the gap between the flat plate 101 and the material discharge conveyor belt 4 can also be adjusted, so that the density of the mineral wool fiber discharge can be controlled according to the actual needs. The material can be discharged while the swing frame 1 is swinging, and two layers of mineral wool are stacked on the cotton pressing conveyor belt 8, which is also convenient for the subsequent cotton pressing process operation.

[0048] like Figure 3 As shown:

[0049] Preferably, the spacing adjustment mechanism 2 includes a mounting frame 201 and two groups of movable frames 3, the two groups of movable frames 3 are slidably connected to two ends of the mounting frame 201, and the two groups of unloading conveyor belts 4 are respectively installed on the two groups of movable frames 3.

[0050] The unloading conveyor belt 4 is installed on the moving frame 3 , and the gap distance between the unloading conveyor belt 4 and the flat plate 101 can be adjusted by adjusting the position of the moving frame 3 .

[0051] Preferably, a horizontal rotating rod 202 is rotatably connected inside the mounting frame 201, and a first thread 203 and a second thread 204 are respectively provided at both ends of the rotating rod 202, and the threads of the first thread 203 and the second thread 204 are in opposite directions. The two ends of the rotating rod 202 are respectively threadedly connected to the two groups of the moving frames 3 through the first thread 203 and the second thread 204, and the rotating rod 202 is rotated to change the spacing between the two groups of the moving frames 3. A first motor 205 is fixedly installed in the middle of the mounting frame 201, and a bevel gear is provided under the first motor 205. A bevel gear matching with the first motor 205 is also provided in the middle of the rotating rod 202, and the first motor 205 drives the rotating rod 202 to rotate through the bevel gear group.

[0052] The preferred solution of the present application is to drive the rotating rod 202 to rotate through the bevel gear set by the first motor 205. Since the threads at both ends of the rotating rod 202 are in opposite directions, the rotation of the rotating rod 202 can synchronously drive the moving frames 3 at both ends to move closer or apart, so as to ensure that the gap spacing between the two sets of unloading conveyor belts 4 and the corresponding flat plates 101 is equal, and the spacing between the two unloading channels is consistent.

[0053] Embodiment 2:

[0054] like Figure 5-6 As shown:

[0055] Preferably, the ejection mechanism 5 includes two groups of moving plates 502 and an elliptical cam 501, the two groups of moving plates 502 are parallel to the two groups of flat plates 101, the elliptical cam 501 is located between the inner side walls of the two groups of moving plates 502, the ejection column 6 is fixedly connected to the outer side walls of the moving plates 502, a plurality of first springs 503 are fixedly connected between the outer side walls of the two groups of moving plates 502 and the inner side walls of the flat plates 101 corresponding thereto, a second motor 504 is installed on the swing frame 1, and the elliptical cam 501 is driven to rotate by the second motor 504;

[0056] Under the action of the first spring 503, the inner side walls of the two sets of moving plates 502 are always in contact with the side walls of the elliptical cam 501. When the second motor 504 drives the elliptical cam 501 to rotate, the moving plates 502 are squeezed to drive the ejector rod to perform reciprocating motion.

[0057] Of course, those skilled in the art can also use a mechanical structure to achieve the same effect to realize the reciprocating motion of the ejector rod, and through the intermittent ejection of the ejector column 6, the mineral wool can be evenly distributed in the gap between the unloading conveyor belt 4 and the flat plate 101 during the transportation process.

[0058] like Figure 7-8 As shown: Further, the top column 6 includes a sleeve 601 and a telescopic column 602, the telescopic column 602 is slidably connected to the inner wall of the sleeve 601, the tail end of the telescopic column 602 is fixedly connected to a second spring 603, the second spring 603 is located in the inner cavity of the sleeve 601, and the top end of the telescopic column 602 is fixedly connected to a rubber pad 604.

[0059] Since the gap between the unloading conveyor belt 4 and the flat plate 101 can be changed, the top column 6 in the present application adopts a telescopic rod structure. When the top end of the top column 6 hits the unloading conveyor belt 4, the rubber pad 604 at its top can play a buffering and protective role, and the internal second spring 603 structure can also play a buffering role, and expand and contract according to the distance between the gaps.

[0060] Embodiment 3:

[0061] like Figure 4 As shown:

[0062] Furthermore, baffles 701 are fixedly mounted on the outer side walls of the two groups of the movable frames 3 , and scrapers 702 are obliquely mounted on the baffles 701 , and the side edges of the scrapers 702 are in close contact with the surface of the unloading conveyor belt 4 .

[0063] In order to prevent the mineral wool fibers from adhering to the surface of the unloading conveyor belt 4 and affecting the subsequent unloading of the mineral wool fibers, the scraper 702 in the present application is close to the surface of the unloading conveyor belt 4, shovels off the mineral wool fibers attached to the unloading conveyor belt 4, and drops them onto the cotton pressing conveyor belt 8 under the action of the baffle 701.

[0064] Furthermore, side plates 801 are fixedly installed on both sides of the cotton pressing conveyor belt 8.

[0065] In order to prevent mineral wool fibers from falling onto the outside of the cotton pressing conveyor belt 8, the side panels 801 are tilted to collect the fibers and ensure the environment in the factory workshop.

[0066] Furthermore, a first feed hopper 901 and a second feed hopper 902 are fixedly installed on both sides of the top of the swing frame 1, and the first feed hopper 901 and the second feed hopper 902 are respectively located above the gap between the two groups of unloading conveyor belts 4 and the swing frame 1. A first feed conveyor belt 903 is provided above the first feed hopper 901, and the end of the conveying direction of the first feed conveyor belt 903 is above the first feed hopper 901. A first feed conveyor belt 903 is provided above the second feed hopper 902, and the end of the conveying direction of the second feed conveyor belt 904 is above the second feed hopper 902.

[0067] Since there are two groups of gaps between the unloading conveyor belt 4 and the flat plate 101, the top of the gap is also fed by two groups of feeding conveying mechanisms. The first feeding conveyor belt 903 and the second feeding conveyor belt 904 respectively deliver the mineral wool fiber material to the first feeding hopper 901 and the second feeding hopper 902 to feed the tops of the two gaps respectively.
