Description

Technical Field

[0001] This utility model relates to the field of rock wool composite board production technology, and more specifically, it relates to a rock wool composite board production device that prevents cracking. Background Technology

[0002] Rock wool composite board is a board made of rock wool (an inorganic fiber made from natural minerals such as basalt as the main raw material, which is melted at high temperature and centrifuged into fibers) as the core material, and bonded to a protective surface layer (such as cement mortar, metal plate, glass cloth or polymer coating) with an adhesive. Its structure is usually "sandwich type": the inner and outer layers are high-strength protective layers, and the middle layer is a rock wool insulation layer, which has the functions of heat insulation, fire resistance, sound insulation and noise reduction.

[0003] The production equipment for preventing cracking of rock wool composite boards needs to be optimized in terms of key aspects such as the dispersion of rock wool fibers, molding process, adhesive performance and environmental control. At the same time, the production equipment for preventing cracking of rock wool composite boards generally includes fiber pretreatment and dispersion equipment, mixing and molding equipment, bonding and interface strengthening equipment, etc.

[0004] The fiber pretreatment and dispersion device, through a fiber pretreatment unit → fiber dispersion unit → dispersion effect detection and feedback device, ensures uniform dispersion of rock wool fibers and reduces defects, thereby significantly reducing the risk of cracking in rock wool composite boards. The fiber dispersion unit generally uses a low-speed rotating stirring shaft, combined with spiral or paddle blades, to form laminar or mild turbulent flow, gradually deflocculating and dispersing fiber bundles, thus reducing the risk of cracking caused by stress concentration and drying shrinkage. In existing mechanical stirring, the distance between stirring blades is generally fixed, which can lead to the stirring blade spacing exceeding the flow range of fiber clusters or matrix materials. The middle area cannot be directly acted upon by the blades, forming a "undisturbed zone," resulting in uneven local fiber dispersion or poor mixing of matrix materials, which in turn leads to the risk of cracking.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a rock wool composite board production device to prevent cracking. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rock wool composite board production device that prevents cracking.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rock wool composite board production device for preventing cracking, comprising a mixing tank, wherein a cover is slidably installed on the upper end of the mixing tank;

[0008] The cover has a drive assembly at its upper end and center, and the drive assembly has a plurality of annular racks A.

[0009] The inner wall of the mixing tank is symmetrically equipped with multiple mixing components B for the middle area that cannot be directly stirred by the blades. Each mixing component B includes a gear A.

[0010] Each of the stirring components B is provided with a scraping component that reciprocates to clean each stirring component B, and each annular rack B in the scraping component can be used to drive each gear A to rotate.

[0011] Preferably, the drive assembly includes a motor, a rotating shaft, and an annular rack A. The motor is connected to the upper end of the cover and at the center position. The output end of the motor is inserted into the rotating shaft. The end of the rotating shaft away from the motor passes through the cover and extends into the interior of the mixing tank. The rotating shaft can rotate on the cover. Multiple annular racks A are installed on the rotating shaft to facilitate control of the rotation of the rotating shaft.

[0012] Preferably, the rotating shaft is provided with a plurality of stirring components A, each stirring component A including a support plate and stirring blades A. The rotating shaft is equipped with a plurality of support plates, and a plurality of stirring blades B are symmetrically mounted on each support plate in a ring. An annular rack A is provided between every two support plates to facilitate stirring of the fibers inside the mixing tank.

[0013] Preferably, each of the stirring components B includes a base, a support rod, a stirring blade B, a flow hole, and a gear A;

[0014] The mixing tank is symmetrically equipped with multiple bases in a ring inside. Each base is rotatably connected to a support rod. Each support rod is symmetrically equipped with multiple stirring blades B. Each stirring blade B has multiple flow holes. Each support rod is connected to a gear A at the end away from the base. Each gear A can mesh with a corresponding annular rack A to facilitate stirring of the fibers between every two stirring blades A.

[0015] Preferably, each scraping assembly includes a connecting rod, a horizontal plate, a groove, an annular rack B, a connecting block, a screw, a gear B, and a scraper. A horizontal plate is rotatably mounted on each support rod between the gear A and each stirring blade B. Each horizontal plate is connected to a corresponding base via a connecting rod. Each horizontal plate has an annular groove, and an annular rack B is connected within each groove. Two connecting blocks are installed on each support rod between every two stirring blades B. Every two connecting blocks on the same horizontal line form a group. A screw is rotatably mounted between each group of connecting blocks. A gear B is connected to the end of each screw near the horizontal plate. Each gear B can be positioned within a corresponding groove and meshes with the annular rack B within the groove. A scraper is installed between two connecting blocks on each screw. Each scraper is in contact with the surface of each adjacent stirring blade B, facilitating cleaning of the surface of each stirring blade B.

[0016] Preferably, the mixing tank and the lid are connected by multiple electric telescopic rods, and a discharge pipe is installed at the bottom of the mixing tank, which communicates with the mixing tank to facilitate the vertical movement of the lid.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this utility model, the stirring assembly B set on the stirring tank causes each ring gear A to reciprocate along with the rotating shaft, and when each gear A reciprocates, each connected support rod and each stirring blade B reciprocates on the base. At this time, each flow hole on each stirring blade B reduces the resistance caused by stirring. By rotating between two stirring blades A, the present invention solves the problem that the stirring blade distance in existing mechanical stirring is generally fixed, which results in the stirring blade distance exceeding the flow range of fiber clusters or matrix materials. The middle area cannot be directly acted upon by the blades, forming a "undisturbed zone", which leads to uneven local fiber dispersion or poor mixing of matrix materials, and thus the risk of cracking.

[0019] 2. In this utility model, the scraping component installed on each base causes the connecting block to reciprocate when each support rod reciprocates on the base. This reciprocating rotation of the connecting block causes each connected screw to reciprocate. The reciprocating rotation of each screw causes each connected gear B to reciprocate within the groove in the horizontal plate. Simultaneously, each gear B reciprocates on the annular rack B. This rotation causes each gear B to rotate on its own axis. This rotation causes the connected screw to rotate between the two connecting blocks. As each screw rotates, the scraper on each screw reciprocates against the surface of the stirring blade B. This reciprocating movement of each scraper against each surface of the stirring blade B effectively removes fibers adhering to each surface of the stirring blade B. This allows for real-time cleaning through the scraper, continuously removing fibers adhering to each surface of the stirring blade B without stopping the machine, thus avoiding manual intervention and significantly improving work efficiency.

[0027] like Figure 1-5 As shown, this utility model provides a rock wool composite board production device to prevent cracking, including a mixing tank 1, which is used to store fibers that need to be mixed, and a cover 2 is slidably installed on the upper end of the mixing tank 1, which is used to close the mixing tank 1.

[0028] The cover 2 has a drive assembly 3 located at its upper end and center. This assembly is used to enable the rotating shaft 302 and each annular rack A303 on the rotating shaft 302 to reciprocate through the start of the motor 301. The drive assembly 3 has multiple annular racks A303 and includes a motor 301, a rotating shaft 302, and annular racks A303. The motor 301 is connected to the upper end and center of the cover 2 and is used to control the reciprocating rotation of the rotating shaft 302. The output end of the motor 301 is inserted into the rotating shaft 302 and is used to transmit power to the annular racks A303. The end of the rotating shaft 302 away from the motor 301 passes through the cover 2 and extends into the interior of the mixing tank 1. The rotating shaft 302 can rotate on the cover 2. Multiple annular racks A303 are installed on the rotating shaft 302 and are used to make the gear A505 meshing with it rotate.

[0029] Multiple stirring components A4 are provided on the rotating shaft 302, which are used to make each support plate 401 and each stirring blade A402 on each support plate 401 rotate by the reciprocating rotation of the rotating shaft 302. Each stirring component A4 includes a support plate 401 and a stirring blade A402. Multiple support plates 401 are installed on the rotating shaft 302, and multiple stirring blades B503 are symmetrically installed on each support plate 401 in a ring, which are used to stir the fibers in the mixing tank 1. A ring rack A303 is provided between every two support plates 401.

[0030] The inner wall of the mixing tank 1 is symmetrically equipped with multiple mixing components B5 that prevent the blades from directly mixing the middle area. Each mixing component B5 includes a gear A505.

[0031] When each ring gear A505 reciprocates with the rotating shaft 302, it causes each gear A505 to reciprocate together. When each gear A505 reciprocates, each connected support rod 502 and each stirring blade B503 reciprocates on the base 501. At this time, each flow hole 504 on each stirring blade B503 reduces the resistance caused by stirring. By rotating each stirring blade B503 between two stirring blades A402, it can effectively ensure that the fibers between the two stirring blades A402 can also be fully stirred, thus solving the problems of many blind spots and uneven fiber dispersion in traditional stirring equipment.

[0032] Each stirring assembly B5 includes a base 501, a support rod 502, a stirring blade B503, a flow hole 504, and a gear A505. Multiple bases 501 are symmetrically mounted in a ring inside the stirring tank 1. A support rod 502 is rotatably connected to each base 501, which is used to drive the stirring blade B503. Multiple stirring blades B503 are symmetrically mounted on each support rod 502, which are used to stir between every two stirring blades A402. Multiple flow holes 504 are provided on each stirring blade B503. A gear A505 is connected to the end of each support rod 502 away from the base 501. Each gear A505 can mesh with a corresponding annular rack A303, which is used to rotate the support rod 502.

[0033] Each stirring component B5 is equipped with a scraping component 6 for reciprocating cleaning of each stirring component B5. Each annular rack B604 in the scraping component 6 can drive each gear A505 to rotate. This is used to ensure that when each support rod 502 reciprocates on the base 501, the connecting block 605 reciprocates as well. When each connecting block 605 reciprocates, each connected screw 606 reciprocates. When each screw 606 reciprocates, it causes each connected gear B607 to reciprocate within the groove 603 in the horizontal plate 602. Simultaneously, each gear B607 reciprocates on the annular rack B604. When the machine reciprocates on 604, each gear B607 rotates. When each gear B607 rotates, the connected screw 606 rotates between the two connecting blocks 605. When each screw 606 rotates, the scraper 608 on each screw 606 moves back and forth against the surface of the mixing blade B503. When each scraper 608 moves back and forth against each surface of each mixing blade B503, the fibers adhering to each surface of each mixing blade B503 are scraped off. This effectively achieves real-time cleaning through the scraper 608, continuously removing fibers adhering to each surface of the mixing blade B503 without stopping the machine, thus avoiding manual intervention and effectively improving work efficiency.

[0034] Each scraping assembly 6 includes a connecting rod 601, a horizontal plate 602, a groove 603, an annular rack B604, a connecting block 605, a screw 606, a gear B607, and a scraper 608. A horizontal plate 602 is rotatably mounted on each support rod 502 between the gear A505 and each stirring blade B503. Each horizontal plate 602 is connected to its corresponding base 501 via a connecting rod 601, ensuring the stability of the horizontal plate 602. Each horizontal plate 602 has an annular groove 603, ensuring the stable rotation of the gear B607. An annular rack B604 is connected within each groove 603, allowing the gear B607 to roll on the rack, thus achieving rotation. Each support rod 502 is positioned between each pair of stirring blades B508. Two connecting blocks 605 are installed between each of the three sections. Each pair of connecting blocks 605 on the same horizontal line is considered a group. A screw 606 is rotatably installed between each group of connecting blocks 605. The screw 606 is used to control the reciprocating movement of the scraper 608 to clean each stirring blade B503. A gear B607 is connected to one end of each screw 606 near the horizontal plate 602. The gear B607 is used to control the rotation of the screw 606. Each gear B607 can be placed in a corresponding groove 603 and meshes with the annular rack B604 in the groove 603. A scraper 608 is installed between each screw 606 and two connecting blocks 605. The scraper 608 is used to clean the surface of each stirring blade B503. Each scraper 608 is in contact with the surface of each adjacent stirring blade B503.

[0035] The mixing tank 1 and the cover 2 are connected by multiple electric telescopic rods 7, which are used to realize the vertical reciprocating movement of the cover 2. The bottom of the mixing tank 1 is equipped with a discharge pipe 8, which is used to discharge the mixed fibers. The discharge pipe 8 is connected to the mixing tank 1.

[0036] Working principle: When it is necessary to disperse the fibers, first activate the electric telescopic rod 7 to move the cover 2 upward, then put the fibers to be dispersed into the mixing tank 1, and then activate the electric telescopic rod 7 to move the cover 2 downward until the cover 2 closes the mixing tank 1.

[0037] Next, start the motor 301 to make the rotating shaft 302 reciprocate. When the rotating shaft 302 reciprocates, it will cause each connected annular rack A303 to rotate. At the same time, the rotation of the rotating shaft 302 will cause each connected support plate 401 to reciprocate. When each support plate 401 reciprocates, it will cause each connected agitator A to reciprocate, thereby stirring the fibers in the mixing tank 1.

[0038] Simultaneously, when each ring gear A505 reciprocates with the rotating shaft 302, multiple gears A505 on each ring rack A303 will reciprocate through the ring rack A303. When each gear A505 reciprocates, each connected support rod 502 will reciprocate on the base 501. When each support rod 502 reciprocates, it will cause each connected stirring blade B503 to reciprocate. When each stirring blade B503 reciprocates, each flow hole 504 on each stirring blade B503 will reduce the resistance caused by stirring. By rotating each stirring blade B503 between two stirring blades A402, it is ensured that the fibers between the two stirring blades A402 are also fully stirred.

[0039] Simultaneously, when each support rod 502 reciprocates on the base 501, the connecting block 605 connected to the support rod 502 will also reciprocate. When each connecting block 605 reciprocates, each connected screw 606 will reciprocate. When each screw 606 reciprocates, it will cause each connected gear B607 to reciprocate within the groove 603 in the horizontal plate 602. Simultaneously, each gear B607 will reciprocate on the annular rack B604. When the ring rack B604 reciprocates, each gear B607 rotates. When each gear B607 rotates, the connected screw 606 rotates between the two connecting blocks 605. When each screw 606 rotates, the scraper 608 on each screw 606 moves back and forth against the surface of the stirring blade B503. When each scraper 608 moves back and forth against each surface of each stirring blade B503, the fibers adhering to each surface of each stirring blade B503 are scraped off.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
