Description

Technical Field

[0001] This invention relates to the field of rock wool board processing technology, specifically to a rock wool board hot pressing molding equipment. Background Technology

[0002] Rock wool board, also known as rock wool insulation and decorative board, is an inorganic fiber board made from basalt as the main raw material through high-temperature melting and processing. Rock wool board is a new type of thermal insulation, fireproof, and sound-absorbing material. Rock wool board is an artificial inorganic fiber processed by high-temperature melting and processing, which has the characteristics of light weight, low thermal conductivity, heat absorption, and non-combustibility. The production of rock wool board generally includes raw material preparation; melting and spraying; molding and curing; cutting and packaging. In the molding process, the upper and lower conveyor belt pressing method is generally used to complete the molding of rock wool board.

[0003] Currently, when using the upper and lower track pressing method to form rock wool boards, a pendulum method is generally used to lay sheet rock wool on the lower track. During the conveying process, the upper track presses the stacked sheet rock wool, thereby pressing multiple layers of sheet rock wool into rock wool boards. At the same time, during the pressing process, extrusion plates are used on the sides to press the sides of the rock wool into the rock wool, thus ensuring that the two sides of the rock wool can be pressed more tightly.

[0004] However, there are still some drawbacks when using the upper and lower track pressing method to press rock wool boards. For example, when pressing sheet rock wool, the sides of the rock wool need to be squeezed by the extrusion plates on both sides of the track to assist in the forming. However, in order to ensure that the extrusion plates do not contact the track during the side extrusion process, the extrusion plates are generally set into long strips. Each extrusion by the extrusion plates will cause the sides of the rock wool layer to be concave. When the track finishes pressing the rock wool, the sides of the rock wool board are uneven, which will increase the workload of subsequent cutting and generate waste material during the trimming and finishing process.

[0005] Furthermore, when using tracks for pressing and molding, since the filamentous rock wool fibers are formed into sheet-like rock wool layers through adhesives, during the pressing process, when the upper track presses the rock wool layer, some rock wool fibers will adhere to the surface of the upper track. Consequently, the surface of the track will be uneven during the subsequent pressing process, and it is difficult to ensure the surface flatness of the rock wool board during the pressing process due to the uneven track surface. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a rock wool board hot pressing molding equipment, which solves the problems mentioned in the background technology.

[0008] The extrusion assembly includes an extrusion plate. A support slot is provided on the top of the extrusion plate near the control box. A magnet is engaged inside the support slot. A receiving trough is slidably connected to the top of the support slot. A magnetic block is slidably connected inside the receiving trough. A scraper is fixed to the outside of the magnetic block.

[0009] A support frame is fixed on the top of the control panel near the first motor, and a shaping component is provided on one side of the support frame.

[0010] The support frame is equipped with a heating component at the top, and shaping rollers are rotatably sleeved on both sides of the bottom of the heating component. The heating component is also equipped with an air inlet at the top.

[0011] Optionally, the material receiving trough is fixed with support columns at both ends, and the bottom of the support columns is fixed to the top of both sides of the operating table. The material receiving trough is hinged with a cover plate.

[0012] Optionally, the shaping component includes a shaping frame, the inner wall of which is fixed with a partition plate, and the partition plate divides the interior of the shaping frame into an exhaust chamber and an air supply chamber. A ventilation filter plate is fixed to the outside of one end of the partition plate, and a rotating shaft is rotatably sleeved inside the partition plate.

[0013] Optionally, a storage box is slidably fitted inside the exhaust cavity, a positive blade is fixed to the outside of the rotating shaft near the support column, and a negative blade is fixed to the outside of the positive blade away from the support column. The positive blade is located inside the exhaust cavity, and the negative blade is located inside the ventilation filter plate. A drive motor is provided outside the positive blade.

[0014] Optionally, the heating assembly includes a heating plate, the heating plate having a heating cavity inside, a heating wire being installed inside the heating cavity, and an arc-shaped groove being provided on the side of the heating cavity near the support column.

[0015] Optionally, air ducts are provided at the bottom of both sides of the heating chamber, and the heating chamber is connected to the air supply chamber through the air ducts.

[0016] Optionally, the bottom end of the outer track of the second motor output shaft is engaged with the inner side of the arc-shaped groove, the top of the scraper is inclined, and the top of the scraper is in contact with the outer track of the second motor output shaft.

[0017] Optionally, the bottom of both the shaping frame and the shaping roller are in contact with the top of the outer track of the first motor output shaft.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The rock wool board hot pressing molding equipment uses a hydraulic cylinder to start the extrusion plate to initially shape the side of the rock wool layer on the external track of the first motor, and the external track of the second motor to press and shape the rock wool layer. During the shaping process, the extrusion plate drives the magnet and attracts the magnetic block to move synchronously, so that while the rock wool layer is being shaped at the top and sides, the surface of the external track of the second motor is cleaned, ensuring the flatness of the top of the rock wool layer after subsequent pressing.

[0020] 2. This rock wool board hot pressing molding equipment uses heating wires installed inside the heating plate. After the top of the rock wool layer is pressed, it enters the inner side of two sets of shaping frames under the guidance of the shaping rollers. When the shaping rollers shape both sides of the rock wool board, the drive motor first removes impurities from both sides of the rock wool board by the positive blades, then the heating wires heat the heating plate, and the heating plate transfers heat to the top of the rock wool board. At the same time, the reverse blades blow hot air to both sides of the rock wool board, heating both sides of the rock wool board again, thereby improving the overall molding and curing speed of the rock wool board.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-9 ,

[0033] Example 1: A rock wool board hot pressing molding equipment includes an operating table 1 and a control box 11. A first motor 12 is provided on one side of the top of the operating table 1, and a track is externally driven to the output shaft of the first motor 12. A second motor 13 is provided on the top of the operating table 1, and a track is externally driven to the output shaft of the second motor 13. The equipment is characterized in that: a support column 2 is fixed on the top of the operating table 1, a hydraulic cylinder 3 is installed on the outside of the support column 2, and an extrusion assembly is provided on the outside of the output shaft of the hydraulic cylinder 3.

[0034] The extrusion assembly includes an extrusion plate 4. The top of the extrusion plate 4 near the control box 11 has a support slot 41. A magnet 42 is engaged inside the support slot 41. A receiving groove 5 is slidably connected to the top of the support slot 41. A magnetic block 52 is slidably connected inside the receiving groove 5. A scraper 53 is fixed to the outside of the magnetic block 52.

[0035] A support frame 6 is fixed on the top of the operating table 1 near the first motor 12. A shaping component is provided on one side of the support frame 6. A heating component is provided on the top of the support frame 6. Shaping rollers 9 are rotatably sleeved on both sides of the bottom of the heating component. An air inlet is provided on the top of the heating component. Support columns 51 are fixed to the outside of both ends of the receiving trough 5, and the bottom of the support columns 51 is fixed to the top of both sides of the operating table 1. A cover plate 54 is hinged to the outside of the receiving trough 5.

[0036] In the specific operation process, the first motor 12 and the second motor 13 are started by the control box 11. The first motor 12 controls the rotation of the track sleeve outside its output shaft, and the second motor 13 controls the rotation of the track sleeve outside its output shaft. This allows both the upper and lower tracks to be driven. Then, the rock wool layer is placed on the surface of the track sleeve outside the first motor 12. The track then propels the rock wool layer forward, and the track outside the second motor 13 presses and shapes the rock wool layer. This is the upper and lower track pressing method used in the existing technology of rock wool board, which will not be described in detail here.

[0037] Furthermore, after the rock wool layer is placed on top of the track outside the first motor 12, the hydraulic cylinder 3 is activated. The hydraulic cylinder 3 pushes the extrusion plate 4 towards the rock wool layer. The angle of inclination of the side of the extrusion plate 4 closest to the track outside the second motor 13 is set to be the same as that of the track. This ensures that the extrusion plate 4 contacts the side of the entire rock wool layer without affecting the track transmission. As a result, the two sides of the rock wool layer become flat under the pressure of the extrusion plate 4, avoiding unevenness on the sides of the rock wool layer. This step completes the initial shaping of the two sides of the rock wool layer. At the same time, when the extrusion plate 4 squeezes... When the two sides of the rock wool layer are shaped, the extrusion plate 4 drives the magnet 42 inside the support slot 41 to move below the receiving trough 5. During the movement of the magnet 42, the magnetic block 52 moves synchronously. The magnetic block 52 drives the scraper 53 to move synchronously. During the movement of the scraper 53, the track surface outside the second motor 13 is cleaned, so that the rock wool fibers adhering to the track surface are scraped off into the receiving trough 5. This avoids the influence of the track surface adhesive on the shaping of the rock wool board during the subsequent track pressing process and improves the flatness of the top surface of the rock wool board.

[0038] After the rock wool board is pressed and shaped, the cover plate 54 can be flipped outward, and then the magnetic block 52 can be taken out from the inside of the receiving trough 5. After that, the magnetic block 52, the scraper 53 and the inner cavity of the receiving trough 5 can be cleaned. After the magnetic block 52 and the scraper 53 are cleaned, they can be placed back into the receiving trough 5, and the magnetic strip 42 can be attracted to the magnetic block 52 for subsequent use.

[0039] As the rock wool board continues to move forward, it is guided by the shaping roller 9 into the inner side of the two shaping frames 7. At this time, the top of the rock wool board has been pressed and can be conveyed to the bottom of the heating plate 8. During the conveying process, the two sides of the rock wool board are limited by the shaping roller 9, and the top of the rock wool board is limited by the heating plate 8. This completes the shaping of the two sides of the rock wool board. As a result, the present invention can remove the fibers adhering to the surface of the conveyor belt while shaping the top and two sides of the rock wool board, improving the flatness of the top and two sides of the rock wool board and avoiding the step of cutting and trimming the two sides of the rock wool board in the subsequent rock wool board production process, thereby improving the efficiency of the device in the production and processing of rock wool boards.

[0040] In embodiment 2, the shaping component includes a shaping frame 7, the inner wall of the shaping frame 7 is fixed with a partition plate 71, and the partition plate 71 divides the interior of the shaping frame 7 into an exhaust chamber 72 and an air supply chamber 73. A ventilation filter plate 74 is fixed to the outside of one end of the partition plate 71, and a rotating shaft 76 is rotatably sleeved inside the partition plate 71.

[0041] A storage box 75 is slidably fitted inside the exhaust cavity 72. A positive blade 77 is fixed to the outside of the rotating shaft 76 near the support column 2. A negative blade 78 is fixed to the outside of the positive blade 77 away from the support column 2. The positive blade 77 is located inside the exhaust cavity 72, and the negative blade 78 is located inside the ventilation filter plate 74. A drive motor 79 is provided on the outside of the positive blade 77.

[0042] The heating assembly includes a heating plate 8, which has a heating cavity 81 inside. A heating wire 82 is installed inside the heating cavity 81. An arc-shaped slot 83 is provided on the side of the heating cavity 81 near the support column 2. Air ducts are provided at the bottom of both sides of the heating cavity 81, and the heating cavity 81 is connected to the air supply cavity 73 through the air ducts.

[0043] Specifically, when the rock wool board enters the inner side of the two sets of shaping frames 7, it first contacts each set of shaping rollers 9 and shapes the sides of the rock wool board through the shaping rollers 9. At this time, the heating wire 82 and the drive motor 79 are started by the control box 11. The drive motor 79 drives the rotating shaft 76 to rotate, and the rotating shaft 76 drives the positive blade fan 77 and the negative blade fan 78 to rotate synchronously. The rotation of the positive blade fan 77 generates suction to draw air from the sides of the rock wool board, so that the fiber debris or incompletely bonded rock wool fibers on the sides of the rock wool board are adsorbed into the inside of the storage box 75, ensuring the integrity of the shaping on both sides of the rock wool board. At the same time, it can remove the rock wool fibers adsorbed on the surface of the shaping rollers 9. After the rock wool board is shaped, the storage box 75 can be pulled out from the inside of the shaping frame 7, and then the debris inside can be cleaned and put back for the next use.

[0044] Furthermore, as the rock wool board continues to be conveyed, the air entering the heating wire 82 through the air inlet at the top of the heating plate 8 is heated by the heating chamber 81, causing the bottom of the heating plate 8 to be heated and the heat to be transferred to the top of the rock wool board through the heating plate 8, thus preheating the rock wool board and increasing the speed of the rock wool board being heated and formed. At the same time, since the heating chamber 81 is connected to the air supply chamber 73, hot air enters the interior of the air supply chamber 73 and, under the rotation of the reverse blade fan 78, is blown to both sides of the rock wool board through the ventilation filter plate 74, preheating both sides of the rock wool board and further increasing the speed of the rock wool board being heated and cured.

[0045] In embodiment three, the bottom end of the outer track of the output shaft of the second motor 13 is engaged with the inner side of the arc-shaped slot 83, the top of the scraper 53 is inclined, and the top of the scraper 53 is in contact with the outer track of the output shaft of the second motor 13. The bottom of the shaping frame 7 and the shaping roller 9 are both in contact with the top of the outer track of the output shaft of the first motor 12.

[0046] Specifically, the arc-shaped groove 83 ensures the smoothness of the external track drive of the second motor 13, and at the same time ensures that after the rock wool board is pressed by the external track of the second motor 13, it can directly adhere to the bottom of the heating plate 8 and be conveyed to the inner side of the two sets of shaping frames 7. The rock wool board is then shaped on both sides by the shaping rollers 9. At the same time, the distance between the two shaping rollers 9 is smaller than the distance between the edges of the two sets of shaping frames 7. This allows the rock wool board to be guided by the shaping rollers 9 when it enters the inner side of the two sets of shaping frames 7. The final shaping of the two sides of the rock wool board is completed by the last set of shaping rollers 9. After completion, the rock wool board can be shaped by passing through the two sets of shaping frames 7.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
