Description

Technical Field

[0001] This invention relates to the field of rock wool board processing technology, and in particular to a rock wool board pre-compression pleating forming equipment and its usage method. 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. It has the characteristics of being lightweight, having a low thermal conductivity, absorbing heat, and being non-combustible, and is therefore used in various industries. In the production process of rock wool board, processing techniques such as high-temperature melting, extrusion, and pleating are required. In particular, during the pleating process of rock wool board, workers often use pleating machines to assist in pleating the rock wool board. By using mechanical equipment to pleat the rock wool board, a wrinkled surface is formed within a certain range, increasing its surface area and improving the sound absorption and heat insulation performance of the rock wool board.

[0003] When pleating rock wool, the rock wool at the edges is often squeezed out. This squeezed-out edge wool, being less dense, cannot be reused. Current technology typically uses baffles on the sides of the rock wool to limit its movement. However, because the baffles restrict the outward spread of the edge wool during pre-compression pleating, the density of the edge wool is concentrated at the point of contact with the baffle, resulting in a higher density at the edges than in the center, thus reducing the quality of the rock wool board. Therefore, the excess rock wool squeezed out at the edges needs to be cut after pleating, adding to the processing steps. Furthermore, the uncompressed edges are loose and uneven, and many rock wool fibers easily fall from the cut edges. These fibers can be inhaled, affecting human health. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to propose a rock wool board pre-compression pleating forming equipment and its usage method.

[0028] When the L-shaped cutter moves downward, it forms a shearing engagement with the support plate, and the remaining edge cotton is sheared and slides into the receiving box along the drop slope.

[0029] Preferably, the capacity expansion component includes:

[0030] An L-shaped push plate is slidably disposed in the inner cavity of the receiving box;

[0031] The push rod is horizontally and fixedly connected to the L-shaped push plate and the sleeve;

[0032] The first filter plate is fixedly installed inside the receiving box;

[0033] The reciprocating motion trajectory of the L-shaped pusher plate covers the surface area of ​​the first filter plate.

[0034] Preferred options also include:

[0035] A water tank is located at the bottom of the receiving box, and the bottom opening of the receiving box is connected to the top opening of the water tank.

[0036] A water pump is fixedly installed on the outside of the water tank, and its outlet end is connected to a drain pipe.

[0037] A drainage board is fixedly installed on the top of the receiving box, and its surface is equipped with multiple spray nozzles;

[0038] The drain pipe is connected to a drain board at its end to form a water mist dust suppression system.

[0039] Preferred options also include:

[0040] The second filter plate is slidably disposed in the inner cavity of the receiving box, and its surface is covered with a sponge layer.

[0041] A pull rope is connected at both ends to the second filter plate and the L-shaped push plate, respectively.

[0042] The first elastic telescopic rod is vertically installed between the bottom of the second filter plate and the inner wall of the water tank;

[0043] When the L-shaped pusher moves forward, it pulls the second filter plate upward by pulling the rope to compress the sponge layer.

[0047] A connecting plate is fixedly mounted on the outer end of the L-shaped push plate;

[0048] The second elastic telescopic rod is disposed between the connecting plate and the inner wall of the receiving box.

[0049] This invention also discloses a method for using a rock wool board pre-compression and pleating forming equipment, comprising the following steps:

[0050] S1: Start the hydraulic cylinder, adjust the height of the upper pleating mechanism to form a gradually narrowing forming gap with the lower pleating mechanism to match the thickness of the rock wool board, turn on the drive motor, and rotate all the pleating rollers through the chain linkage to ensure that their surface speed matches the rock wool board conveying speed.

[0051] S2: Rock wool board is fed into the pre-compression and pleating section from the front end of the frame. As it passes through the gradually narrowing gap, the upper and lower pleating rollers rotate synchronously to progressively compress the board and form a uniform pleated structure.

[0052] S3: When the pleated rock wool board is moved to the support board area:

[0053] The rotating shaft drives the reciprocating screw to rotate through the meshing of the active bevel gear and the driven bevel gear. The sleeve moves along the axial direction of the reciprocating screw at the same speed as the rock wool board conveying speed. The electric push rod pushes the L-shaped cutter downward, and the transverse and longitudinal blades simultaneously cut the loose edge cotton on the side of the rock wool board. The length of the cutter covers twice the stroke of the reciprocating screw, ensuring that it can still cut continuously during the return stroke.

[0054] S4: The sheared edge cotton slides into the receiving box along the dropping slope. The sleeve drives the L-shaped push plate to move back and forth through the push rod, squeezing and expanding the broken material on the first filter plate to reduce the fluffy volume.

[0055] S5: The water pump draws water from the water tank and delivers it to the drainage plate through the drain pipe. The water mist sprays out to suppress the rock wool fibers from flying during cutting. The dusty water is coarsely filtered by the first filter plate and then finely filtered by the sponge layer of the second filter plate. The clean water flows back to the water tank for recycling.

[0056] S6: When the L-shaped push plate moves forward, it pushes the L-shaped partition to move towards the inner wall of the receiving box through the connecting plate and the second elastic telescopic rod. The spring is compressed. When the L-shaped partition abuts against the inner wall of the receiving box, the filter holes of the first filter plate and the through holes of the L-shaped partition are no longer aligned. Then the second elastic telescopic rod begins to be compressed.

[0057] When the L-shaped push plate moves forward, it simultaneously pulls the second filter plate upward through the pull rope to compress the sponge layer. Since the upper side of the sponge layer is blocked, the water can only quickly seep into the water tank.

[0058] When the L-shaped pusher plate is reset, the spring pushes the L-shaped partition plate to reset, the through hole is realigned with the filter hole of the first filter plate, and the filtration channel is restored.

[0059] Compared with the prior art, the present invention provides a rock wool board pre-compression pleating forming device and its usage method, which has the following beneficial effects:

[0060] 1. The rock wool board pre-compression pleating forming equipment and its usage method directly cut off loose edge wool during the movement of the rock wool board through the synchronous shearing component, avoiding the uneven side density caused by the compression of traditional baffles, reducing subsequent cutting processes, integrating pre-compression pleating, synchronous shearing, and scrap collection functions, reducing process changeover time, and significantly improving the pleating quality, production efficiency, and production environment safety of rock wool boards.

[0061] 2. The rock wool board pre-compression pleating forming equipment and its usage method, by setting up an expansion component, the dynamic extrusion mechanism (L-shaped push plate + first filter plate) can be adapted to edge wool with different loft, avoiding frequent cleaning of the receiving box, effectively increasing the collection capacity of the receiving box for sheared material, and reducing the workload and work intensity of the staff.

[0062] 3. The rock wool board pre-compression pleating forming equipment and its usage method reduce the dust concentration in the workshop through the water circulation dust suppression system, prevent the rock wool fibers generated during shearing from being absorbed by the human body, and ensure a safe working environment. When the second filter plate is pulled upward by the rope, the sponge layer is compressed and drained. At the same time, the L-shaped partition holes are misaligned to form a seal, forcing water to seep down only through the micropores of the second filter plate, achieving efficient solid-liquid separation, ensuring the water supply inside the water tank, and thus ensuring the continuous operation of dust suppression.

Detailed Implementation

[0075] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0076] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0077] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, this embodiment proposes a pre-compression and pleating forming equipment for rock wool boards, belonging to the field of rock wool board processing technology. The rock wool board is horizontally fed into the pre-compression and pleating section 2 from the inlet end of the frame 1. The hydraulic cylinder 14 is started, and the height of the upper pleating mechanism 202 is adjusted so that the gradually narrowing forming gap formed with the lower pleating mechanism 201 is adapted to the thickness of the board (adjustable from 5-50mm). Multiple pleating rollers 401 are arranged in the frame 4 of both the lower pleating mechanism 201 and the upper pleating mechanism 202. Each roller is linked by a movable gear and a chain. The transmission of the chain and movable gear is existing technology and will not be described in detail here. After the drive motor is started, the rotating shaft 4011 drives all the pleating rollers 401 to rotate at the same linear speed (the speed is set to 0.5-2m / s). When the rock wool board passes through the gradually narrowing gap, the upper and lower pleating rollers 401 cooperate to apply pressure, and the fibers on the board surface are gradually compressed to form a three-dimensional pleated structure (pleat depth adjustable from 3-15mm). The three inclined frames (15°-30° inclination angle) of the upper pleating mechanism 202 guide the deformation direction of the board, so that the rock wool board is gradually pre-compressed, which solves the problem that the internal structure of the rock wool is damaged or deformed due to sudden pressure application in existing devices; the hydraulic cylinder 14 has a stroke of 200mm and a response time of ≤0.3s, and works with the pressure sensor to adjust the height of the gradually narrowing gap in real time (control accuracy ±0.1mm).

[0078] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, in a preferred embodiment, based on the above method, further, when the rock wool board moves to the area of ​​the support plate 7, the driving bevel gear 5012 at the end of the rotating shaft 4011 meshes with the driven bevel gear 5011, driving the reciprocating screw 501 to rotate on the support plate 5. The reciprocating screw 501 is provided with bidirectional guide stroke for the sleeve 502 to reciprocate along the axial direction of the reciprocating screw 501. The sleeve 502 slides on the outside of the frame 4. The sleeve 502 moves along the axial direction of the reciprocating screw 501 (at the same speed as the board conveying speed), driving the L-shaped cutter 602 on the connecting frame 6 to move laterally. The electric push rod 601 pushes the L-shaped cutter 602 downward, laterally and longitudinally. Simultaneously cut off both sides of the edge cotton on the same side of the rock wool board with the blade, separating the cut edge cotton from the edge cotton on the side of the rock wool board (cutting accuracy ±0.3mm). After the L-shaped cutter 602 finishes cutting, the sleeve 502 has not yet moved to the end of the reciprocating screw 501 near the receiving box 3. Control the L-shaped cutter 602 to move upward and reset. After the sleeve 502 moves to the end of the reciprocating screw 501 near the receiving box 3, it begins to move back. The length of the L-shaped cutter 602 is at least twice the one-way stroke of the reciprocating screw 501, so that after the L-shaped cutter 602 moves back to the initial position with the sleeve 502, the L-shaped cutter 602 can continue to move downward and cut the previous rock wool board edge cotton cutting position.

[0079] like Figure 4 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, the cut-off edge cotton slides along the material drop slope 701 of the support plate 7 into the receiving box 3.

[0080] The sleeve 502 drives the L-shaped push plate 8 to reciprocate within the receiving box 3 via the push rod 801, compacting the broken material onto the surface of the first filter plate 10, thus preventing the broken material in the receiving box 3 from being too fluffy and occupying too much space. The effective volume of the receiving box 3 is increased to 1.5 times that of the traditional design.

[0081] like Figure 4 and Figure 10 As shown, in a preferred embodiment, based on the above method, the water pump 901 further draws cooling water (temperature ≤25℃) from the water tank 9 and delivers it to the drainage plate 903 through the drain pipe 902. The water mist at a level of 50μm is formed through the nozzle to cover the cutting area (coverage rate ≥0.8m²), so that the concentration of rock wool dust generated during cutting is reduced to below 5mg / m³.

[0082] like Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in a preferred embodiment, based on the above method, the water containing rock wool fibers is further filtered by the sponge layer 112 on the second filter plate 11 after coarse filtration by the first filter plate 10 (filtration efficiency 95%).

[0083] When the L-shaped push plate 8 moves forward, the second filter plate 11 is pulled upward by the pull rope 802 to compress the sponge layer 112. The first elastic telescopic rod 111 is stretched and squeezed to absorb sewage into the water tank 9 for recycling.

[0084] like Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in a preferred embodiment, based on the above method, when the L-shaped push plate 8 moves forward, the connecting plate 13 and the second elastic telescopic rod 131 push the L-shaped partition 12 to move towards the inner wall of the receiving box 3. The spring 121 is compressed. When the L-shaped partition 12 abuts against the inner wall of the receiving box 3, the filter holes of the first filter plate 10 are no longer aligned with the through holes of the L-shaped partition 12. Subsequently, the second elastic telescopic rod 131 begins to be compressed. When the L-shaped push plate 8 moves forward, the second filter plate 11 is simultaneously pulled upward by the pull rope 802 to compress the sponge layer 112. Since the upper side of the sponge layer 112 is blocked, the water can only quickly seep into the water tank 9, achieving efficient solid-liquid separation and ensuring the water supply inside the water tank 9, thereby ensuring the continuous operation of dust suppression. When the L-shaped push plate 8 resets, the spring 121 pushes the L-shaped partition 12 to reset, and the through holes are realigned with the filter holes of the first filter plate 10, restoring the filtration channel.

[0085] This invention also discloses a method for using a rock wool board pre-compression and pleating forming equipment, comprising the following steps:

[0086] S1: Start the hydraulic cylinder 14, adjust the height of the upper pleating mechanism 202 to form a gradually narrowing forming gap with the lower pleating mechanism 201 to match the thickness of the rock wool board, turn on the drive motor, and rotate all the pleating rollers 401 through the chain linkage to ensure that their surface speed matches the rock wool board conveying speed.

[0087] S2: The rock wool board is fed into the pre-compression and pleating section 2 from the front end of the frame 1. When it passes through the gradually narrowing gap, the upper and lower pleating rollers 401 rotate synchronously to gradually compress the board and form a uniform pleated structure.

[0088] S3: When the pleated rock wool board is moved to area 7 of the support board:

[0089] The rotating shaft 4011 meshes with the driven bevel gear 5011 via the driving bevel gear 5012, driving the reciprocating screw 501 to rotate. The sleeve 502 moves axially along the reciprocating screw 501, with a speed consistent with the rock wool board conveying speed. The electric push rod 601 pushes the L-shaped cutter 602 downward, and the transverse and longitudinal blades simultaneously cut the loose edge cotton on the side of the rock wool board. The length of the cutter covers twice the stroke of the reciprocating screw 501, ensuring continuous cutting during the return stroke.

[0090] S4: The sheared edge cotton slides into the receiving box 3 along the dropping slope 701. The sleeve 502 drives the L-shaped push plate 8 to move back and forth through the push rod 801, squeezing and expanding the broken material on the first filter plate 10 to reduce the fluffy volume.

[0091] S5: Water pump 901 draws water from water tank 9 and delivers it to drainage plate 903 through drain pipe 902. Water mist is sprayed to suppress the rock wool fibers from flying during cutting. The dusty water is coarsely filtered by first filter plate 10 and finely filtered by sponge layer 112 of second filter plate 11. The clean water flows back to water tank 9 for recycling.

[0092] S6: When the L-shaped push plate 8 moves forward, it pushes the L-shaped partition 12 toward the inner wall of the receiving box 3 through the connecting plate 13 and the second elastic telescopic rod 131. The spring 121 is compressed. When the L-shaped partition 12 abuts against the inner wall of the receiving box 3, the filter holes of the first filter plate 10 and the through holes of the L-shaped partition 12 are no longer aligned. Then the second elastic telescopic rod 131 begins to be compressed.

[0093] When the L-shaped push plate 8 moves forward, it simultaneously pulls the second filter plate 11 upward through the pull rope 802 to compress the sponge layer 112. Since the upper side of the sponge layer 112 is blocked, the water can only quickly seep into the water tank 9.

[0094] When the L-shaped push plate 8 is reset, the spring 121 pushes the L-shaped partition 12 to reset, the through hole is realigned with the filter hole of the first filter plate 10, and the filtration channel is restored.

[0095] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0096] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

A method of using the rock wool board pre-compression and pleating forming equipment according to claim 4, characterized in that, Includes the following steps: S1: Start the hydraulic cylinder (14), adjust the height of the upper pleating mechanism (202) to form a gradually narrowing forming gap with the lower pleating mechanism (201) to match the thickness of the rock wool board, turn on the drive motor, and rotate all the pleating rollers (401) through the chain linkage to ensure that their surface speed matches the conveying speed of the rock wool board. S2: The rock wool board is fed from the front end of the frame (1) into the pre-pressing and pleating section (2). When passing through the gradually narrowing gap, the upper and lower pleating rollers (401) rotate synchronously to gradually compress the board and form a uniform pleated structure. S3: When the rock wool board with pleats completed is moved to the area of ​​the support board (7): The rotating shaft (4011) meshes with the driven bevel gear (5011) through the driving bevel gear (5012), driving the reciprocating screw (501) to rotate. The sleeve (502) moves axially along the reciprocating screw (501) at the same speed as the rock wool board conveying speed. The electric push rod (601) pushes the L-shaped cutter (602) downward, and the transverse and longitudinal blades simultaneously cut the loose edge cotton on the side of the rock wool board. The length of the cutter covers twice the stroke of the reciprocating screw (501), ensuring that it can still cut continuously during the return stroke. S4: The sheared edge cotton slides into the receiving box (3) along the dropping slope (701). The sleeve (502) drives the L-shaped push plate (8) to move back and forth through the push rod (801) to squeeze and expand the broken material on the first filter plate (10) and reduce the fluffy volume. S5: The water pump (901) draws water from the water tank (9) and delivers it to the drainage plate (903) through the drain pipe (902). The water mist sprays out to suppress the rock wool fibers from flying during cutting. The dusty water is coarsely filtered by the first filter plate (10) and then finely filtered by the sponge layer (112) of the second filter plate (11). The clean water flows back to the water tank (9) for recycling. S6: When the L-shaped push plate (8) moves forward, it pushes the L-shaped partition (12) towards the inner wall of the receiving box (3) through the connecting plate (13) and the second elastic telescopic rod (131). The spring (121) is compressed. When the L-shaped partition (12) abuts against the inner wall of the receiving box (3), the filter holes of the first filter plate (10) and the through holes of the L-shaped partition (12) are no longer aligned. Then the second elastic telescopic rod (131) begins to be compressed. When the L-shaped push plate (8) moves forward, it simultaneously pulls the second filter plate (11) upward through the pull rope (802) to compress the sponge layer (112). Since the upper side of the sponge layer (112) is blocked, the water can only quickly seep into the water tank (9). When the L-shaped push plate (8) is reset, the spring (121) pushes the L-shaped partition (12) to reset, and the through hole is realigned with the filter hole of the first filter plate (10) to restore the filtration channel.
