Description

Technical Field

[0001] The invention relates to the technical field of rock wool board production, and in particular to a trimming device for rock wool board production. Background Art

[0002] Rock wool board, also known as rock wool thermal insulation decorative board, is made of basalt and other natural minerals as the main raw materials. After melting, the high-temperature melt of basalt cotton rock is pulled into non-continuous fibers of 4 to 7 μm, and then a certain amount of adhesive, dust-proof oil, and water-repellent are added to the rock wool fibers. After sedimentation, solidification, cutting and other processes, it is processed into artificial inorganic fibers. Due to the special process of the rock wool board manufacturing process, when it is cut, the high-speed rotating saw blade will pull and bring out the internal fibers, thereby forming flocculent fiber clusters on the cutting surface, and pits will be formed at the locations where these fiber clusters are pulled out. When it is installed as a fireproof material, these lumps will directly affect the degree of fit between the two side walls of the two boards during installation, and the fiber burrs of varying lengths on the cutting surface are also prone to safety hazards.

Detailed implementation mode

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0017] First, the concepts involved in this application will be described in conjunction with the accompanying drawings. It should be noted here that the following descriptions of each concept are only for making the content of this application easier to understand, and do not represent a limitation on the protection scope of this application; at the same time, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Next, this application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0018] As Figures 1 to 7 shown, an embodiment of a trimming device for producing rock wool boards provided by the present invention includes a conveyor belt 1 for conveying the rock wool board 2. The rock wool board 2 can also be pressed by existing pressing equipment above the rock wool board 2. It also includes a fiber mass cleaning mechanism 3, a shearing mechanism 4, a collection mechanism 5, and a grinding mechanism 6 arranged in sequence along the advancing direction of the conveyor belt 1. The fiber mass cleaning mechanism 3 includes a rotating shaft 7 and a plurality of hanging teeth 8. The plurality of hanging teeth 8 are equidistantly arranged on the rotating surface of the rotating shaft 7, and the hanging teeth 8 are used to pull the fiber mass at the edge of the rock wool board 2.

[0019] The fiber mass cleaning mechanism 3 further includes a cleaning motor 13, a mounting bracket 14, a cutting knife 15, and a tool rest 16. The mounting bracket 14 is fixedly connected to the side of the conveyor belt 1. The tool rest 16 is fixed on the mounting bracket 14. The cutting knife 15 is fixed on one side of the tool rest 16 and can be attached to the side of the rock wool board 2. The cutting knife 15 is used to cut the fiber mass from the rock wool board 2. The cleaning motor 13 is fixed on the mounting bracket 14, and the output shaft of the cleaning motor 13 is coaxially and fixedly connected to the rotating shaft 7.

[0020] When the rotating shaft 7 drives the hanging tooth 8 to move, the hanging tooth 8 can sweep across the edge of the rock wool board 2. When the fiber mass contacts the hanging tooth 8, it will be pulled up by the hanging tooth 8. At this time, there are only a small number of fibers connecting the fiber mass and the rock wool board 2. When the rock wool board 2 continues to move forward, the fibers between the fiber mass and the rock wool board 2 will touch the cutting knife 15, and then the fibers will be cut off by the cutting knife 15, so that the fiber mass is completely separated from the rock wool board 2. The separated fiber mass is driven by the hanging tooth 8 to move away from the rock wool board 2.

[0021] The shearing mechanism 4 includes a sliding frame 9 and a plurality of pairs of upper blades 10 and lower blades 11. One ends of the upper blades 10 and the lower blades 11 are rotatably mounted on the sliding frame 9 through torsion springs. The upper blades 10 and the lower blades 11 are arranged at an angle. Extrusion blocks 12 are arranged on the outer sides of each pair of upper blades 10 and lower blades 11. The upper blades 10 and the lower blades 11 are slidably connected to the inner sides of the extrusion blocks 12. The upper blades 10 and the lower blades 11 are used for shearing the fiber burrs at the edge of the rock wool board 2. The collecting mechanism 5 is fixed to the bottom of the fiber mass cleaning mechanism 3 for collecting the fiber mass and the fiber burrs. The grinding mechanism 6 is used for grinding the edge of the rock wool board 2.

[0022] The shearing mechanism 4 further includes a fixing frame 17 and a fiber guiding frame 18. The fixing frame 17 is fixedly connected to the side of the conveyor belt 1. Both sides of the sliding frame 9 are connected to the fixing frame 17 through guide rails. The fiber guiding frame 18 is connected to one side of the fixing frame 17. A tooth groove 19 is provided at the front end of the fiber guiding frame 18. The upper blades 10 and the lower blades 11 are slidably arranged on the side of the tooth groove 19 away from the rock wool board 2. The upper blades 10 and the lower blades 11 can shear the fiber burrs located in the tooth groove 19.

[0023] A push plate 20 is slidably mounted on the tool rest 16. One side of the push plate 20 is fixedly connected to the sliding frame 9 through a connecting rod 21. The connecting rod 21 passes through the mounting bracket 14 and is slidably connected to the mounting bracket 14. A return spring 22 abuts against the part of the connecting rod 21 between the mounting bracket 14 and the push plate 20. When the rotating shaft 7 drives the hanging tooth 8 to rotate, the hanging tooth 8 can push the push plate 20 and drive the connecting rod 21 and the sliding frame 9 to move.

[0024] The working principle of the shearing mechanism 4 is as follows: During the forward movement of the rock wool board 2, the fibers at its edge first come into contact with the limit guide frame. Then, as the rock wool board 2 continues to move, the fibers at the edge gradually gather into the tooth grooves 19 at the front end of the limit guide frame. At this time, the rotating shaft 7 rotates and drives the connecting rod 21 and the sliding frame 9 to move through the hanging teeth 8. When the sliding frame 9 moves, it drives the upper blade 10 and the lower blade 11 to move. When the upper blade 10 and the lower blade 11 move, the outer sides of the two are squeezed inward by the extrusion blocks 12, causing the upper blade 10 and the lower blade 11 to approach each other. Since one end of the upper blade 10 and the lower blade 11 is rotatably connected to the sliding frame 9, when the upper blade 10 and the lower blade 11 are squeezed and approach each other, a shearing action can be achieved, thereby cutting the long fibers in the tooth grooves 19 at the front end of the guide frame. The cut long fibers fall into the collection mechanism 5 for collection, preventing fiber fluttering.

[0025] On one side of the rotating shaft 7, a cleaning scraper 23 is also fixed. A cleaning slot 24 for avoiding the hanging teeth 8 is provided on the cleaning scraper 23. The hanging teeth 8 can pass through the cleaning slot 24 when moving. The fiber clusters cut during the movement of the hanging teeth 8 will adhere to the hanging teeth 8. When the hanging teeth 8 pass through the cleaning slot 24, the fiber clusters will be blocked and fall to the collection mechanism 5, and the hanging teeth 8 that have completed cleaning will continue to move to clean the subsequent fiber clusters.

[0026] The collection mechanism 5 includes a material guide frame 25 and a storage box 26. The material guide frame 25 is fixed below the mounting bracket 14. The inner wall of the material guide frame 25 is inclined downward. The storage box 26 is fixed at the bottom of the material guide frame 25 and is communicated with the material guide frame 25. The cut fiber clusters and long fibers naturally fall to the material guide frame 25 and then slide down the inner wall of the material guide frame 25 into the storage box 26 for collection.

[0027] The grinding mechanism 6 includes a grinding bracket 27, an electric grinding roller 28, a cleaning nozzle 29, a nozzle pile 30, and a liquid inlet pipe 31. The grinding bracket 27 is fixed on the side of the conveyor belt 1. The electric grinding roller 28 is rotatably installed on the grinding bracket 27. The nozzle pile 30 is arranged on one side of the electric grinding roller 28 and is fixedly connected to the grinding bracket 27. A plurality of cleaning nozzles 29 are provided, and the plurality of cleaning nozzles 29 are fixed on the nozzle pile 30 and are communicated with the liquid inlet pipe 31.

[0028] After the fiber clusters and long fibers at the edge of the rock wool board 2 are sheared off, there will still be some short fiber burrs remaining on the edge of the rock wool board 2. At this time, the short fiber burrs are polished by the electric grinding roller 28, which can effectively prevent the fibers from winding around the electric grinding roller 28, and the short fibers are more easily cleaned by the electric grinding roller 28. On the one hand, the time required for grinding can be shortened, and on the other hand, less debris and dust are generated. The cleaning liquid is conveyed into the cleaning nozzle 29 through the liquid inlet pipe 31, and then the cleaning liquid is sprayed out through the cleaning nozzle 29 to clean the surface of the electric grinding roller 28, ensuring the grinding effect of the electric grinding roller 28 and further reducing the dust.

[0029] In this article, specific examples are used to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. The above is only the preferred implementation manner of the present application. It should be noted that due to the limited nature of written expression and objectively existing infinite specific structures, for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements, retouches or changes can be made, or the above technical features can be combined in an appropriate manner; these improvements, retouches, changes or combinations, or directly applying the inventive concept and technical solution to other occasions without improvement, should all be regarded as the protection scope of the present application.
