Description

Technical Field

[0001] The invention relates to the technical field of sound-absorbing board processing, in particular to a high-strength moisture-proof and flame-retardant mineral wool sound-absorbing board and processing equipment. Background Art

[0002] Severe noise pollution endangers people's living and working environment. Sound-absorbing board is an ideal sound-absorbing decorative material. According to the classification of manufacturing materials, there are mainly wood, mineral wool and fabric sound-absorbing board. Mineral wool sound-absorbing board is a decorative material integrating multiple functions such as sound absorption, heat insulation, easy processing and good decorativeness. The warning of building fire makes people pay special attention to the fire safety of decorative materials including sound-absorbing board. At the same time, with the expansion of the use environment of materials and the improvement of people's quality requirements, mineral wool sound-absorbing board with high strength mechanical properties, moisture-proof and deformation-proof, flame retardant and fire-resistant safety is pursued by the market. However, the market lacks such mineral wool sound-absorbing board with good comprehensive performance. Therefore, the present invention provides a high-strength moisture-proof and flame-retardant mineral wool sound-absorbing board;

[0003] In the process of existing sheet metal processing, the sheet metal can only be simply stamped. However, during processing, not only stamping is performed, but also trimming is required. The existing stamping equipment can only complete the stamping work, and the trimming work needs to be performed separately, which will increase the overall processing time and increase the processing and production costs. After processing and stamping, the working end cannot be processed. If manual operation is performed, the labor intensity and labor cost will increase over time, and it will also affect the normal stamping operations in the later stage. Summary of the invention

[0004] The object of the present invention is to provide a high-strength moisture-proof and flame-retardant mineral wool sound-absorbing board and processing equipment to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a high-strength moisture-proof and flame-retardant mineral wool sound-absorbing board, comprising the mineral wool sound-absorbing board containing the following raw materials in parts by weight: 50-53 parts of mineral wool, 3-4 parts of gray wood fiber, 5-6 parts of waste newspaper, 18-20 parts of perlite, 7-9 parts of industrial flour, 2-3 parts of polyvinyl butyral (PVB) powder, 4-6 parts of perchlorinated paraffin (CP-70) powder, 1.5-2.5 parts of silicone moisture-proof agent, 4-5 parts of glass mesh cloth fragments, 8-10 parts of aluminum hydroxide, 0.2-0.3 parts of borax, and 0.2-0.3 parts of alum.

[0006] In this technical solution, mineral wool and perlite give the board the functions of sound absorption and heat insulation; gray wood fiber has a reinforcing effect; waste newspapers are mixed with water to form a slurry, which not only plays a role in waste utilization but also increases strength; (1) Industrial flour is innovatively used in the formulation of mineral wool sound-absorbing panels.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The invention firstly innovatively uses industrial flour in the formula of mineral wool sound-absorbing board. The industrial flour is gelatinized and hardened during the high-temperature drying process of the slurry, thereby increasing the strength of the mineral wool sound-absorbing board. The flame retardant high-chlorinated paraffin powder is innovatively used in the formula of the mineral wool sound-absorbing board, and the board is moisture-proof and flame-retardant through melting, penetration and solidification. The glass mesh cloth is innovatively cut into pieces of a certain size and used in the formula of the mineral wool sound-absorbing board to increase its strength. At the same time, waste newspapers are used in the formula of the mineral wool sound-absorbing board, which not only plays the role of waste utilization but also increases the strength. The cross-linking of the hydroxyl group of polyvinyl butyral and borax also plays the role of enhancing its bonding force and moisture resistance. Through the synergistic effect of various materials in the formula, a high-strength, moisture-proof and flame-retardant mineral wool sound-absorbing board is obtained to meet the market demand.

[0031] When the punching mechanism is used for punching, the limit switching mechanism is triggered to start the trimming mechanism through the limit switching mechanism. In addition, during the punching process of the sheet, the punched sheet can be trimmed and cut at the same time, which can not only increase the processing efficiency, but also reduce the steps after the overall processing, reduce the processing cost, avoid the need to process the sheet separately after the punching process, which leads to the lengthening of the overall processing flow and time, thereby increasing the processing cost. The limit switching mechanism is used to trigger the limit stabilizing mechanism, and the limit stabilizing mechanism is used to increase the firmness and stability during the punching process, so as to avoid excessive pressure during punching and accidental sliding. The punching force during punching is reduced, resulting in the sheet being unable to be processed and formed during punching, and further processing is required at a later stage, which increases the processing time and processing cost.

[0032] The present invention simultaneously starts the stabilizing pulling mechanism through the stamping mechanism, and starts the processing mechanism through the stabilizing pulling mechanism, so that the upper end of the worktable is automatically processed after stamping and trimming, and not only large pieces of residues but also small particles of residues can be processed during the processing, so that the processing process is more thorough, and in the processing process, automatic processing and resetting are performed without manual operation, which increases the convenience of use and reduces the operating steps of later processing, so that the next stamping work can be carried out as soon as possible, thereby increasing the efficiency of use and reducing the intensity of work.

When the stabilizing slide block 706 moves downward, the reset push rod 707 is separated from the inside of the movable opening. When the stabilizing slide block 706 moves to the bottom end of the inner cavity of the stabilizing slide groove 702, the contact between the magnetic block 703 and the adsorption iron ring 708 is generated by pulling the magnetic block 703.

[0097] The limit switching mechanism 6 also includes a fixed magnetic block 603, a fixed electromagnetic block 604, a fixed slot 605 and a fixed guide plate 606. The fixed slot 605 is opened in the middle of the inner cavity of the fixed block 601. Four fixed electromagnetic blocks 604 are respectively installed around the inner cavity of the fixed slot 605 by bolts, and four fixed guide plates 606 are respectively installed around the inner cavity of the fixed slot 605 by bolts. The four fixed magnetic blocks 603 are respectively installed at the top of the limit rod 308 by bolts at a relative position of the fixed guide plate 606.

The fixed electromagnetic block 604 and the electric push rod 301 are electrically connected with the pressure controller 306.

[0098] The specific implementation method is as follows: when performing stamping processing, the raw material plate is placed on the top of the workbench 1, and the electric push rod 301 is started to drive the fixed block 601 and the limit rod 308 to move downward, thereby driving the fixed stamping plate 303 and the movable stamping plate 302 to move downward, and the telescopic end of the electric push rod 301 will not be fully extended during stamping, so that the bottom end of the movable stamping plate 302 contacts the top of the plate, and when the fixed stamping plate 303 continues to move downward, the bottom end of the fixed stamping plate 303 contacts and squeezes the top of the movable stamping plate 302, and when the fixed stamping plate 303 is pressed, the fixed stamping plate 303 is pressed downward, and the fixed stamping plate 303 is pressed downward.

After the movable top block 304 moves toward the upper end of the inner cavity of the movable recess 305, the movable top block 304 will contact and squeeze with the bottom end of the pressure controller 306. When the received pressure reaches the value set in advance, the fixed electromagnetic block 604 will be triggered to disconnect the electric power of the fixed electromagnetic block 604. The fixed electromagnetic block 604 loses its magnetism, and the fixed guide plate 606 loses its magnetism, and loses its magnetic attraction constraint force with the fixed magnetic block 603, which causes the fixed block 601 to lose its constraint force with the limit rod 308. The electric push rod 301 is activated by the pressure controller 306 to drive the fixed block 601 to continue to move downward. When the fixed block 601 moves downward, the fixed rod 404 and the rectangular cutting plate 401 are driven to move downward. When the rectangular cutting plate 401 moves downward, the guide slider 402 is driven to slide inside the guide slide rail 403, and the rectangular cutting plate 401 is increased. The cutting plate 401 has stability and guidance when it moves downward. When the rectangular cutting plate 401 moves downward, the extra corners after extrusion are trimmed and cut by the rectangular cutting plate 401. In the process of stamping the plate, the stamped plate can also be trimmed and cut. This not only increases the efficiency of processing, but also reduces the steps after the overall processing, reduces the cost after processing, and avoids the need to process the plate separately after the stamping process, which makes the overall processing process and time longer, thereby increasing the processing cost.

[0099] The limiting and stabilizing mechanism 8 also includes a limiting notch 801, a limiting top block 802, a movable magnetic block 803 and a reset spring rod 805. The four limiting notches 801 are opened at the lower end of the limiting rod 308 located at the fixed magnetic block 603. The four limiting top blocks 802 are movably installed in the middle of the opposite side of the inner cavity of the surrounding mounting grooves 804. The end of the limiting top block 802 away from the mounting groove 804 is engaged with the inside of the limiting notch 801. Several round balls are movably installed around the periphery, four movable magnetic blocks 803 are respectively installed on the side of the limit top block 802 close to the installation slot 804 by bolts, several reset spring rods 805 are respectively installed on the inner side of the installation slot 804 by bolts, and the ends of the reset spring rods 805 away from the installation slot 804 are connected to the limit top block 802 by bolts, and the reset spring rods 805 are all in a stretched state, and the side of the movable magnetic block 803 away from the limit top block 802 is the positive pole;

[0100] The specific implementation is as follows: when the fixed electromagnetic block 604 is started, the fixed guide plate 606 generates positive magnetism, and through the principle of like charges repelling each other, the movable magnetic block 803 and the limit top block 802 are pushed to move to the side away from the installation slot 804, so that the limit top block 802 is docked with the inner cavity of the limit recess 801, thereby increasing the firmness between the limit rod 308 and the fixed block 601; when the circuit of the fixed electromagnetic block 604 is disconnected, the fixed guide plate 606 loses its magnetism, and the movable magnetic block 803 and the limit top block 802 lose their restraining force, and the reset spring rod in the stretched state is reset. 805 drives the limiting top block 802 to move toward the inner cavity of the installation slot 804, so that the limiting top block 802 is separated from the limiting recess 801, and the restraining force between the fixed block 601 and the limiting rod 308 is lost, so that the fixed block 601 can slide outside the limiting rod 308, and the firmness and stability during stamping are increased through the limiting treatment, and excessive pressure during stamping is avoided, which may cause accidental sliding. The stamping pressure during stamping is reduced, resulting in the sheet material being unable to be processed and formed during stamping, and further processing is required at a later stage, which increases the processing time and the processing cost.

[0101] Working principle: When the present invention is punching, the raw material plate is placed on the top of the workbench 1, and the electric push rod 301 is started to drive the fixed block 601 and the limit rod 308 to move downward, which drives the fixed punching plate 303 and the movable punching plate 302 to move downward, and the telescopic end of the electric push rod 301 will not be fully extended during punching, so that the bottom end of the movable punching plate 302 contacts the top of the plate. When the fixed punching plate 303 continues to move downward, the bottom end of the fixed punching plate 303 contacts and squeezes the top of the movable punching plate 302. When the plate 303 continues to move downward, the movable top block 304 will move toward the upper end of the inner cavity of the movable recess 305, and the fixed spring 307 will be stretched. Later, the stretched fixed spring 307 will drive the movable top block 304 and the movable stamping plate 302 to move and reset. After the movable top block 304 moves toward the upper end of the inner cavity of the movable recess 305, the movable top block 304 will contact and squeeze with the bottom end of the pressure controller 306. When the received pressure reaches the value set in advance, the fixed electromagnetic block 604 will be triggered to disconnect the electric power of the fixed electromagnetic block 604. The fixed electromagnetic block 604 loses its magnetism, and the fixed guide plate 606 loses its magnetism, and loses its magnetic attraction constraint force with the fixed magnetic block 603, which causes the fixed block 601 to lose its constraint force with the limit rod 308. The electric push rod 301 is activated by the pressure controller 306 to drive the fixed block 601 to continue to move downward. When the fixed block 601 moves downward, the fixed rod 404 and the rectangular cutting plate 401 are driven to move downward. When the rectangular cutting plate 401 moves downward, the guide slider 402 is driven to slide inside the guide slide rail 403, and the rectangular cutting plate 401 is increased. The cutting plate 401 has good stability and guidance when it moves downward. When the rectangular cutting plate 401 moves downward, the rectangular cutting plate 401 can be used to trim and cut the extra corners after extrusion. In addition, during the stamping process of the plate, the stamped plate can also be trimmed and cut. This can not only increase the efficiency of the processing, but also reduce the steps after the overall processing, reduce the cost after the processing, and avoid the need to process the plate separately after the stamping process, which will make the overall processing process and time longer, thereby increasing the processing cost.

[0102] When the fixed electromagnetic block 604 is started, the fixed guide plate 606 generates positive magnetism, and through the principle of like charges repelling each other, the movable magnetic block 803 and the limit top block 802 are pushed to the side away from the installation slot 804, so that the limit top block 802 is docked with the inner cavity of the limit recess 801, thereby increasing the firmness between the limit rod 308 and the fixed block 601. When the circuit of the fixed electromagnetic block 604 is disconnected, the fixed guide plate 606 loses its magnetism, and the movable magnetic block 803 and the limit top block 802 lose their restraining force, and the reset spring rod 805 in the stretched state is brought into contact with the inner cavity of the limit recess 801. The movable limit top block 802 moves toward the inner cavity of the installation slot 804, so that the limit top block 802 is separated from the limit recess 801, so that the restraining force between the fixed block 601 and the limit rod 308 is lost, so that the fixed block 601 can slide outside the limit rod 308, and the firmness and stability during the stamping process are increased by the limit processing, so as to avoid the situation of excessive pressure during stamping and accidental sliding, thereby reducing the stamping force during stamping, resulting in the sheet material being unable to be processed and formed during stamping, and further processing is required at a later stage, which increases the processing time and the processing cost;

[0103] When the fixed stamping plate 303 moves downward, it will drive the stabilizing slide bar 701 to move downward, and drive the stabilizing slide block 706 to move toward the bottom of the inner cavity of the stabilizing slide groove 702, thereby increasing the stability and flexibility of the fixed stamping plate 303 and the movable stamping plate 302 when moving. When the stabilizing slide block 706 moves downward, the reset push rod 707 is separated from the inside of the movable passage. When the stabilizing slide block 706 moves to the bottom of the inner cavity of the stabilizing slide groove 702, a magnetic connection is generated by pulling the magnetic block 703 into contact with the adsorption iron ring 708. When the stamping and trimming are completed and the fixed stamping plate 303 is moved upward to reset, the pulling magnetic block 703 is driven upward, and the pulling rope 704 is driven to move. When the pulling rope 704 moves, the moving slider 503 is driven to move to the left side of the inner cavity of the moving slide groove 505, and the moving rod 501 and the cleaning brush plate 502 are driven to move from right to left on the top of the workbench 1, so that the residues after trimming on the upper end of the workbench 1 are cleaned, and the moving slider 503 is stretched when it moves, and the reset spring 508 is stretched later. After that, the reset spring 508 drives the moving slider 503 to reset, and when the stabilizing slider 706 moves to the top of the inner cavity of the stabilizing slide groove 702, the reset push rod 707 passes through the movable opening to push the pulling magnetic block 703 open, and the pulling magnetic block 703 is separated and reset from the adsorption iron ring 708. When the moving slider 503 moves, the extrusion airbag 506 is squeezed, and the gas inside the extrusion airbag 506 is pressed into the porous jet slot 504 through the gas delivery hole 507, and the gas is sprayed to the top of the workbench 1 through the gas holes with an inclined structure, and the small particles of residue are processed. By automatically processing the upper end of the workbench 1 after stamping and trimming, and during the processing, not only large pieces of residue can be processed, but also small particles of residue can be processed, the processing process is more thorough, and in the process of processing, through automatic processing and resetting, no manual operation is required to increase the convenience of use, reduce the operation steps of later processing, and can carry out the next stamping work as soon as possible, increase the efficiency of use and reduce the intensity of work.
