Description

Technical Field

[0001] This invention relates to the field of rock wool strip production technology, specifically to a cross-cutting device and method for rock wool strip production. Background Technology

[0002] Because there are many types of fireproof isolation strips and a wide range of processing widths, it is necessary to frequently change and adjust the number and spacing of cutters on the main shaft. However, conventional rock wool equipment has the main shaft mounted on bearing seats at both ends. Fixing the main shaft in this way is not conducive to quick disassembly and assembly of the equipment, and replacing cutters and maintenance are time-consuming and labor-intensive, making the equipment difficult to disassemble and assemble. The produced product has a width of 600mm, which cannot be directly used to produce fireproof isolation strips with a thickness of 50-150mm required in construction projects. In addition, during the cutting of rock wool strips, the rock wool strips are prone to clogging and deviation. Chinese patent number CN116619581B discloses a "Rock Wool Board Cutting Device". In this patent, a telescopic rod drives the circular saw blade of the cutting mechanism into the cutting position, so that the appropriate cutting mechanism can be selected for cutting according to the width of the rock wool board, while the circular saw blades of other cutting mechanisms do not rotate, thereby reducing the energy consumption of the equipment and improving the service life of the equipment. Multiple cutting mechanisms are connected to a synchronous equidistant drive mechanism. When adjusting the distance of the circular saw blades of the cutting mechanism, the synchronous equidistant drive mechanism can make the distance between multiple adjacent circular saw blades change synchronously and keep the distance between adjacent circular saw blades the same.

[0003] Existing cross-cutting equipment and methods for rock wool strip production have structural design flaws. These flaws include the tendency for rock wool blocks to deviate during the cutting process, affecting cutting accuracy, and the extrusion cutting process causing the rock wool block cross-section to be compressed, resulting in defects such as warping and deformation at the cut surface. Summary of the Invention

[0004] This invention provides a cross-cutting device and method for producing rock wool strips, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cross-cutting device and method for producing rock wool strips, comprising a support platform, a first motor fixedly connected to the upper part of the support platform surface, a rotating roller fixedly connected to the output end of the first motor, a spacer ring fixedly connected to the surface of the rotating roller, and a friction belt sleeved on the surface of the rotating roller, and further comprising:

[0006] The positioning push block mechanism has its bottom fixedly installed above the surface of the support platform. There are several friction belts. The surface of the positioning push block mechanism is fixedly connected to the top of the friction belt near the first motor. The positioning push block mechanism is used for clamping the corners of the rock wool block and limiting the rock wool block during the cutting process.

[0007] A reciprocating cutting mechanism, the bottom of which is fixedly installed on the surface of the support platform near the middle, is used to saw rock wool blocks into multiple rock wool strips;

[0008] The positioning push block mechanism includes a guide rail, the bottom of which is fixedly installed above the surface of the support platform. A driving component is slidably connected to the inner side of the guide rail. An electric cylinder is fixedly connected to the top of the driving component. A telescopic rod is fixedly connected to the shaft at the output end of the electric cylinder. A clamping component is fixedly connected to the output end of the telescopic rod.

[0009] Preferably, the end of the driving component away from the guide rail is fixedly installed on the top of the friction belt near the first motor. There are two clamping components, which are used to limit and clamp the rock wool block. The rock wool block is placed above the friction belt. The edge of the rock wool block has a higher hardness, while the surface of the rock wool block has a lower hardness. Applying clamping force or pressure to the surface of the rock wool block will cause the rock wool block to deform. The squeezing force of the clamping force will cause the rock wool block to be in a squeezed state when it is cut, resulting in the cutting surface being skewed when the clamping force is removed after the rock wool strip is cut. In this device, the electric cylinder drives the clamping component to move downward, and at the same time the telescopic rod pushes the clamping component closer to the rock wool block, so that the opposing clamping components are engaged. The rock wool block is pushed and limited by the clamping components. At this time, the corner of the rock wool block is in close contact with the clamping component.

[0010] Preferably, the driving component includes a slider, and a guide pulley is rotatably connected to the surface of the slider near the guide rail. The surface of the guide rail has a hole, and the surface of the guide pulley is rolledly mounted on the surface of the guide rail near the hole.

[0011] Preferably, the driving assembly further includes a bending rod and a concave cylinder. The bottom end of the bending rod is fixedly installed on the surface of the slider, and the bottom of the concave cylinder is fixedly installed on the top of the friction belt near the first motor. The top end of the bending rod is interference-fitted with the inner side of the concave cylinder. The corners of the rock wool block are completely attached to the inner sides of the first L-shaped plate, the second L-shaped plate, the straight plate, and the right-angle plate. The device is provided with multiple friction belts, and the position between each two friction belts is blocked by a spacer ring. The position of the bending rod surface near the end face is restricted by the concave cylinder. When the friction belt drives the rock wool block and the bending rod to approach the reciprocating cutting mechanism, the slider slides on the inner side of the guide rail, and the surface of the guide pulley rolls on the guide rail surface near the opening.

[0012] Preferably, the clamping assembly includes a first L-shaped plate, the surface of which is fixedly mounted on the output end of the telescopic rod, and a second L-shaped plate is fixedly connected to the bottom of the first L-shaped plate.

[0013] Preferably, the clamping assembly further includes a right-angle plate, the top of which is fixedly installed on the end face of the second L-shaped plate. A straight plate is fixedly connected to the surface of the right-angle plate, and a C-shaped frame is fixedly connected to the surface of the straight plate. The opposing clamping assemblies clamp the corners of the rock wool block. While the support assembly provides fixed support for the sawing assembly, the support assemblies positioned at the top and bottom drive the sawing assembly to move up and down reciprocally. The friction belt drives the rock wool block and the clamping assembly closer to the sawing assembly. The rock wool block is cut into rock wool strips of uniform width by the up-and-down moving sawing assembly, and the clamping assembly is fixed to the friction belt, so that the moving speed of the clamping assembly is the same as the moving speed of the rock wool block.

[0014] Preferably, the reciprocating cutting mechanism includes a first lead screw slide, the bottom of which is fixedly installed on the surface of the support platform near the center, and a hydraulic cylinder is fixedly connected to the output end of the first lead screw slide.

[0015] Preferably, the reciprocating cutting mechanism further includes a second lead screw slide, the surface of which is fixedly installed on the upper part of the inner side of the support platform. The output end of the hydraulic cylinder is fixedly connected to a limiting platform, and a support assembly is fixedly connected to the surface of the limiting platform. There are two support assemblies, and a sawing assembly is installed between the two support assemblies. Bolts fix the sawing blade to the inner side of the fixed shell. The upper and lower fixed shells limit the top and bottom ends of the sawing blade. When the sawing blade needs to be replaced, the rotating cover is opened, the bolt at the upper position is unscrewed, the hydraulic cylinder drives the limiting platform to move upward, and then the sawing blade is separated from the fixed shell at the lower position, thus completing the replacement of the sawing blade. During cutting, the second motor drives the eccentric wheel to rotate rapidly on the inner side of the rectangular frame.

[0016] Preferably, the support assembly includes a fixed platform, the bottom of which is fixedly mounted on the surface of the limiting platform, rollers are rotatably connected to the inner side of the fixed platform, a housing is fixedly connected to the top of the fixed platform, and a rotating cover is rotatably connected to the lower part of the surface of the housing.

[0017] Preferably, the support assembly further includes a second motor, the output end of which is fixedly connected to an eccentric wheel. A slide rod is slidably connected to the inner side of the housing, and a rectangular frame is fixedly connected to the bottom end of the slide rod. A fixed shell is fixedly connected to the bottom of the rectangular frame. The sawing blade is located in the middle of the gap between every two friction strips, and the width between every two sawing blades is determined by the width of the rock wool strip. Driven by the electric cylinder and the telescopic rod, the bottom of the second L-shaped plate and the straight plate are in close contact with the top of the rock wool block, and the inner side of the first L-shaped plate is in close contact with the side of the rock wool block. External force pushes the rock wool block to slide on the surface of the friction strip close to the straight plate until it is in contact with the straight plate. The corners of the rock wool block are limited but the internal structure is not squeezed and deformed.

[0018] Preferably, the sawing assembly includes a sawing strip, the surface of which extends to the inner side of the fixing shell near the end face, and the fixing shell and the sawing strip are connected by a bolt via a thread, and the surface of the sawing strip is provided with serrations.

[0019] A cross-cutting method for producing rock wool strips includes the following steps:

[0020] Step 1: Clamping and limiting. Place the rock wool block above the friction belt. The electric cylinder drives the clamping assembly to move downward. At the same time, the telescopic rod pushes the clamping assembly closer to the rock wool block, so that the opposing clamping assemblies match. The rock wool block is pushed and limited by the clamping assembly. At this time, the corners of the rock wool block are in close contact with the clamping assembly. External force pushes the rock wool strip to fully fit the clamping assembly.

[0021] Step 2: Synchronous drive. When the friction belt drives the rock wool block and bending rod close to the reciprocating cutting mechanism, the slider slides on the inner side of the guide rail, and the surface of the guide pulley rolls on the surface of the guide rail near the opening. The sliding of the slider allows the impurities deposited on the inner side of the guide rail to fall through the opening, thereby avoiding blockage of the slider movement. The rock wool block and bending rod are pushed, and the softer side, top and bottom of the rock wool block are not subjected to compressive force.

[0022] Step 3: Reciprocating sawing. While the support component provides fixed support for the sawing component, the support components set at the upper and lower positions drive the sawing component to move up and down reciprocally. The friction belt drives the rock wool block and the clamping component closer to the sawing component. The rock wool block is cut into rock wool strips of uniform width by the up-and-down moving sawing component. When the rock wool block is cut by the sawing component, its corner position is effectively restricted to prevent the rock wool block from being deflected by the cutting force.

[0023] Step 4: Complete the cutting. The fixed table supports and limits the rollers and the housing. The surfaces of multiple rollers are in close contact with the surface of the saw blade near the end face. The rectangular frame drives the saw blade to move up and down quickly, and the saw teeth cut the rock wool block. The limiting of the second L-shaped plate makes it difficult for the rock wool block to deviate. After the rock wool block is cut, the saw blade is inserted into the interior of the C-shaped frame. The rock wool block will not be scattered throughout the entire cutting process.

[0024] This invention provides a cross-cutting device and method for producing rock wool strips. It has the following beneficial effects:

[0025] 1. The cross-cutting equipment and method for rock wool strip production involves an external force pushing the rock wool strip to fully adhere to the clamping component. Then, the first motor drives the rotating roller to rotate, which in turn drives the component to be fixed with the friction belt. The clamping component and the friction belt synchronously approach the reciprocating cutting mechanism. The relatively soft surface of the rock wool block is not subjected to extrusion pressure, and the edge position of the rock wool block is limited. This solves the problem that the rock wool block is prone to deviation and affects the cutting accuracy during the rock wool strip production and cutting process.

[0026] 2. The cross-cutting equipment and method used for rock wool strip production: The sliding of the slider allows impurities deposited on the inner side of the guide rail to fall through the opening, thereby avoiding blockage of the slider movement. The rock wool block and bending rod are pushed. The softer sides, top and bottom of the rock wool block are not subjected to compressive force. The harder corners are clamped and limited. Without the rock wool block deviating, the rock wool block is not subjected to compressive force during cutting. After the clamping force is removed, the cut surface of the rock wool block is flatter.

[0027] 3. The cross-cutting equipment and method for producing rock wool strips effectively restricts the corner position of the rock wool block when it is cut by the sawing component, preventing the rock wool block from being deflected by the cutting force. The spaced friction belts enable the support component to drive the sawing component to move back and forth quickly, so that the rock wool block is cut quickly. Moreover, the rock wool block is not subjected to extrusion pressure during the cutting process, which solves the problem of extrusion cutting causing the rock wool block cross-section to be squeezed during the cutting process, and the defects such as warping and deformation at the cut surface are easy to form.

[0028] 4. The cross-cutting equipment and method for producing rock wool strips, with the eccentric setting of the eccentric wheel, causes the rectangular frame to move up and down reciprocally on the inner side of the shell, so that the sawing blade can quickly cut the rock wool block. During this process, the second motor rotates in the same direction. The use of the eccentric wheel to replace the hydraulic reciprocating movement will not cause sudden stop impact or hydraulic reverse impact, making the vertical movement of the rectangular frame more stable and the structure less prone to damage. The sliding guide of the slide rod makes the rectangular frame more stable and reliable when moving up and down quickly.

[0029] 5. The cross-cutting equipment and method for producing rock wool strips: A rectangular frame moves smoothly up and down on the inner side of the housing; a fixed table supports and limits the rollers and housing; the surfaces of multiple rollers are in close contact with the surface of the sawing blade near the end face; the rectangular frame drives the sawing blade to move up and down quickly; the saw teeth cut the rock wool blocks; the limiting of the second L-shaped plate prevents the rock wool blocks from deviating; and after the rock wool blocks are cut, the sawing blade enters the interior of the C-shaped frame, so the rock wool blocks will not disperse during the entire cutting process, thus avoiding the problem of deviating when the rock wool blocks are finally cut.

[0040] 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.

[0041] First embodiment: as follows Figures 1-4 As shown, the present invention provides a technical solution: a cross-cutting device and method for producing rock wool strips, including a support platform 1, a first motor 2 fixedly connected to the upper position of the surface of the support platform 1, a rotating roller 3 fixedly connected to the output end of the first motor 2, a spacer ring 4 fixedly connected to the surface of the rotating roller 3, and a friction belt 5 sleeved on the surface of the rotating roller 3, and further including:

[0042] The positioning push block mechanism 6 is fixedly installed at the top of the support platform 1. There are several friction belts 5. The surface of the positioning push block mechanism 6 is fixedly connected to the top of the friction belt 5 near the first motor 2. The positioning push block mechanism 6 is used for clamping the corner of the rock wool block and limiting the rock wool block during the cutting process.

[0043] The reciprocating cutting mechanism 7 is fixedly installed at the bottom of the support platform 1 near the middle. The reciprocating cutting mechanism 7 is used to cut the rock wool block into multiple rock wool strips.

[0044] The positioning push block mechanism 6 includes a guide rail 61. The bottom of the guide rail 61 is fixedly installed above the surface of the support platform 1. The inner side of the guide rail 61 is slidably connected to a drive component 62. The top of the drive component 62 is fixedly connected to an electric cylinder 63. The output shaft of the electric cylinder 63 is fixedly connected to a telescopic rod 64. The output end of the telescopic rod 64 is fixedly connected to a clamping component 65.

[0045] One end of the drive component 62 away from the guide rail 61 is fixedly installed on the top of the friction belt 5 near the position of the first motor 2. There are two clamping components 65, which are used for limiting and clamping the rock wool block.

[0046] In use, the rock wool block is placed above the friction band 5. The edges of the rock wool block are harder than the surface. Applying clamping force or pressure to the surface of the rock wool block will cause it to deform. The squeezing force will keep the rock wool block under compression during cutting, causing the cut surface to be skewed when the clamping force is removed after the rock wool strip is cut. In this device, the electric cylinder 63 drives the clamping component 65 to move downward, while the telescopic rod 64 pushes the clamping component 65 closer to the rock wool block, so that the opposing clamping components... When the rock wool block is clamped and limited by the clamping component 65, the corners of the rock wool block are in close contact with the clamping component 65. After the external force pushes the rock wool strip to fully adhere to the clamping component 65, the first motor 2 drives the rotating roller 3 to rotate, which drives the component 62 to be fixed with the friction belt 5. The clamping component 65 and the friction belt 5 move towards the reciprocating cutting mechanism 7 in sync. The relatively soft surface of the rock wool block is not subjected to extrusion pressure, and the edge position of the rock wool block is limited, which solves the problem that the rock wool block is prone to deviating and affecting the cutting accuracy during the production and cutting of rock wool strips.

[0047] Second embodiment: as follows Figure 4 , Figure 5 , Figure 6As shown, the driving component 62 includes a slider 621. A guide pulley 622 is rotatably connected to the surface of the slider 621 near the guide rail 61. A hole is formed on the surface of the guide rail 61, and the guide pulley 622 is rolled on the surface of the guide rail 61 near the hole. The driving component 62 also includes a bent rod 623 and a concave cylinder 624. The bottom end of the bent rod 623 is fixedly installed on the surface of the slider 621, and the bottom of the concave cylinder 624 is fixedly installed on the top of the friction belt 5 near the position of the first motor 2. The top of the clamping assembly 65 is interference-fitted with the inner side of the concave cylinder 624. The clamping assembly 65 includes a first L-shaped plate 651, the surface of which is fixedly mounted on the output end of the telescopic rod 64. The bottom of the first L-shaped plate 651 is fixedly connected to a second L-shaped plate 652. The clamping assembly 65 also includes a right-angle plate 653, the top of which is fixedly mounted on the end face of the second L-shaped plate 652. The surface of the right-angle plate 653 is fixedly connected to a straight plate 654, and the surface of the straight plate 654 is fixedly connected to a C-shaped frame 655.

[0048] In use, the edges and corners of the rock wool block are perfectly fitted to the inner surfaces of the first L-shaped plate 651, the second L-shaped plate 652, the straight plate 654, and the right-angle plate 653. The device is equipped with multiple friction bands 5, and each pair of friction bands 5 is separated by a spacer ring 4. The surface of the bending rod 623 near its end face is restricted by the concave cylinder 624. When the friction bands 5 drive the rock wool block and the bending rod 623 close to the reciprocating cutting mechanism 7, the slider 621 slides on the inner surface of the guide rail 61, and the surface of the guide roller 622... The surface of the rock wool block rolls near the opening on the guide rail 61. The sliding of the slider 621 allows impurities deposited on the inner side of the guide rail 61 to fall through the opening, thus preventing the slider 621 from moving and blocking. The rock wool block and the bending rod 623 are pushed. The softer side, top and bottom of the rock wool block are not subjected to compressive force. The harder corners are clamped and limited. Without tilting the rock wool block, it is not subjected to compressive force during cutting. After the clamping force is removed, the cut surface of the rock wool block is flatter.

[0049] Third embodiment: as follows Figure 4 , Figure 7As shown, a drive assembly 62 is slidably connected to the inner side of the guide rail 61. An electric cylinder 63 is fixedly connected to the top of the drive assembly 62. A telescopic rod 64 is fixedly connected to the shaft at the output end of the electric cylinder 63. A clamping assembly 65 is fixedly connected to the output end of the telescopic rod 64. The reciprocating cutting mechanism 7 includes a first lead screw slide 71. The bottom of the first lead screw slide 71 is fixedly installed on the surface of the support platform 1 near the middle. A hydraulic cylinder 72 is fixedly connected to the output end of the first lead screw slide 71. The reciprocating cutting mechanism 7 also includes a second lead screw slide 73. The surface of the second lead screw slide 73 is fixedly installed above the inner side of the support platform 1. A limit platform 74 is fixedly connected to the output end of the hydraulic cylinder 72. A support assembly 75 is fixedly connected to the surface of the limit platform 74. There are two support assemblies 75, and a sawing assembly 76 is installed between the two support assemblies 75.

[0050] In use, the opposing clamping components 65 clamp the corners of the rock wool block, while the support components 75 provide fixed support for the sawing components 76. Simultaneously, the vertically positioned support components 75 drive the sawing components 76 to move up and down reciprocally. The friction belt 5 pulls the rock wool block and clamping components 65 closer to the sawing components 76. The rock wool block is cut into uniformly wide strips by the vertically moving sawing components 76. The drive components 62 are fixed to the friction belt 5, ensuring that the moving speed of the clamping components 65 is the same as the moving speed of the rock wool block. The corners of the rock wool block are effectively restricted during cutting by the sawing components 76, preventing the rock wool block from tilting due to the cutting force. The spaced friction belts 5 allow the support components 75 to drive the sawing components 76 to move rapidly back and forth, enabling the rock wool block to be cut quickly without being subjected to compressive force. This solves the problem of defects such as warping and deformation at the cut surface caused by compression cutting.

[0051] Fourth embodiment: as Figure 7 , Figure 8 , Figure 9As shown, the support assembly 75 includes a fixed platform 751, the bottom of which is fixedly mounted on the surface of the limiting platform 74. A roller 752 is rotatably connected to the inner side of the fixed platform 751. A housing 753 is fixedly connected to the top of the fixed platform 751. A rotating cover 754 is rotatably connected to the lower part of the surface of the housing 753. The support assembly 75 also includes a second motor 755. An eccentric wheel 756 is fixedly connected to the output end of the second motor 755. A slide rod 758 is slidably connected to the inner side of the housing 753. A rectangular frame 757 is fixedly connected to the bottom end of the slide rod 758. A fixed shell 759 is fixedly connected to the bottom of the rectangular frame 757. The sawing assembly 76 includes a sawing blade 761. The surface of the sawing blade 761 extends to the inner side of the fixed shell 759 near its end face. A bolt 763 is threadedly connected between the sawing blade 761 and the support assembly 75. The surface of the sawing blade 761 is provided with saw teeth 762.

[0052] In use, bolt 763 secures the saw blade 761 to the inner side of the fixed housing 759. The upper and lower fixed housings 759 limit the top and bottom ends of the saw blade 761. When the saw blade 761 needs to be replaced, the rotating cover 754 is opened, the bolt 763 in the upper position is unscrewed, the hydraulic cylinder 72 drives the limiting platform 74 to move upward, and then the saw blade 761 is separated from the fixed housing 759 in the lower position, thus completing the replacement of the saw blade 761. During cutting, the second motor 755 drives the eccentric wheel 756 in the rectangular frame 757. The inner side rotates rapidly, and the eccentric setting of the eccentric wheel 756 causes the rectangular frame 757 to move up and down reciprocally on the inner side of the housing 753, so that the sawing blade 761 can quickly cut the rock wool block. During this process, the second motor 755 rotates in the same direction. Using the eccentric wheel 756 to replace the hydraulic reciprocating movement will not cause sudden stop impact or hydraulic reverse impact, making the vertical movement of the rectangular frame 757 more stable and the structure less prone to damage. The sliding guide of the slide rod 758 makes the rectangular frame 757 more stable and reliable when moving up and down rapidly.

[0053] Fifth embodiment: as follows Figure 6 , Figure 8 As shown, the surface of the first L-shaped plate 651 is fixedly installed on the output end of the telescopic rod 64. The bottom of the first L-shaped plate 651 is fixedly connected to the second L-shaped plate 652. The clamping assembly 65 also includes a right-angle plate 653. The top of the right-angle plate 653 is fixedly installed on the end face of the second L-shaped plate 652. A straight plate 654 is fixedly connected to the surface of the right-angle plate 653. A C-shaped frame 655 is fixedly connected to the surface of the straight plate 654. The surface of the sawing blade 761 extends to the inner side of the fixing shell 759 near the end face. The position between the sawing blade 761 and the support assembly 75 is connected by a bolt 763 through a thread. The surface of the sawing blade 761 is provided with saw teeth 762.

[0054] In use, the saw blade 761 is positioned in the middle of the gap between every two friction bands 5, and the width between every two saw blades 761 is determined by the width of the rock wool strip. Driven by the electric cylinder 63 and the telescopic rod 64, the bottom of the second L-shaped plate 652 and the straight plate 654 are in close contact with the top of the rock wool block, and the inner side of the first L-shaped plate 651 is in close contact with the side of the rock wool block. External force pushes the rock wool block to slide on the surface of the friction band 5 and approach the straight plate 654 until it is in contact with the straight plate 654. The corners of the rock wool block are limited but the internal structure is not squeezed and deformed. Rectangular frame 7 57 moves smoothly up and down on the inner side of the housing 753. The fixed platform 751 supports and limits the rollers 752 and the housing 753. The surfaces of multiple rollers 752 are in close contact with the surface of the saw blade 761 near the end face. The rectangular frame 757 drives the saw blade 761 to move up and down quickly. The saw teeth 762 cut the rock wool block. The limiting of the second L-shaped plate 652 makes it difficult for the rock wool block to deviate. Furthermore, after the rock wool block is cut, the saw blade 761 is inserted into the interior of the C-shaped frame 655. The rock wool block will not be scattered throughout the entire cutting process, thus avoiding the problem of the rock wool block deviating when it is finally cut.

[0055] Sixth embodiment: as follows Figures 1-9 As shown, a cross-cutting method for producing rock wool strips includes the following steps:

[0056] Step 1: Clamping and limiting. Place the rock wool block above the friction belt 5. The electric cylinder 63 drives the clamping component 65 to move downward. At the same time, the telescopic rod 64 pushes the clamping component 65 closer to the rock wool block, so that the opposing clamping components 65 are engaged. The rock wool block is pushed and limited by the clamping component 65. At this time, the corner of the rock wool block is in close contact with the clamping component 65. The external force pushes the rock wool strip to fully adhere to the clamping component 65.

[0057] Step 2: Synchronous drive. When the friction belt 5 drives the rock wool block and bending rod 623 close to the reciprocating cutting mechanism 7, the slider 621 slides on the inner side of the guide rail 61, and the surface of the guide pulley 622 rolls on the surface of the guide rail 61 near the opening. The sliding of the slider 621 allows the impurities deposited on the inner side of the guide rail 61 to fall through the opening, thereby avoiding the slider 621 from moving and blocking. The rock wool block and bending rod 623 are pushed, and the softer side, top and bottom of the rock wool block are not subjected to compressive force.

[0058] Step 3: Reciprocating sawing. While the support component 75 provides fixed support for the sawing component 76, the support component 75, which is set at the upper and lower positions, drives the sawing component 76 to move up and down reciprocally. The friction belt 5 drives the rock wool block and the clamping component 65 to approach the sawing component 76. The rock wool block is cut into rock wool strips of uniform width by the up and down moving sawing component 76. When the rock wool block is cut by the sawing component 76, its corner position is effectively restricted to prevent the rock wool block from being deflected by the cutting force.

[0059] Step 4: Complete the cutting. The fixed table 751 supports and limits the rollers 752 and the housing 753. The surfaces of the multiple rollers 752 are in close contact with the surface of the saw blade 761 near the end face. The rectangular frame 757 drives the saw blade 761 to move up and down quickly. The saw teeth 762 cut the rock wool block. The limiting effect of the second L-shaped plate 652 makes it difficult for the rock wool block to deviate. After the rock wool block is cut, the saw blade 761 is inserted into the interior of the C-shaped frame 655. The rock wool block will not be scattered throughout the entire cutting process.

[0060] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

7. The cross-cutting method of the cross-cutting equipment for rock wool strip production according to claim 6, characterized in that, Includes the following steps: Step 1: Clamping and limiting. Place the rock wool block above the friction belt (5). The electric cylinder (63) drives the clamping assembly (65) to move downward. At the same time, the telescopic rod (64) pushes the clamping assembly (65) closer to the rock wool block, so that the opposing clamping assemblies (65) are engaged. The rock wool block is pushed and limited by the clamping assembly (65). At this time, the corner of the rock wool block is in close contact with the clamping assembly (65). The external force pushes the rock wool strip to fully adhere to the clamping assembly (65). Step 2: Synchronous drive. When the friction belt (5) drives the rock wool block and bending rod (623) close to the reciprocating cutting mechanism (7), the slider (621) slides on the inner side of the guide rail (61), and the surface of the guide pulley (622) rolls on the surface of the guide rail (61) near the opening. The sliding of the slider (621) allows the impurities deposited on the inner side of the guide rail (61) to fall through the opening, thereby avoiding the movement of the slider (621) from being blocked. The rock wool block and bending rod (623) are pushed, and the softer side, top and bottom of the rock wool block are not subjected to compressive force. Step 3: Reciprocating sawing. While the support component (75) provides fixed support for the sawing component (76), the support component (75) at the upper and lower positions drives the sawing component (76) to move up and down reciprocally. The friction belt (5) drives the rock wool block and the clamping component (65) to approach the sawing component (76). The rock wool block is cut into rock wool strips of uniform width by the sawing component (76) moving up and down. When the rock wool block is cut by the sawing component (76), its corner position is effectively restricted to prevent the rock wool block from being deflected by the cutting force. Step 4: Complete the cutting. The fixed table (751) supports and limits the rollers (752) and the housing (753). The surfaces of multiple rollers (752) are in close contact with the surface of the saw blade (761) near the end face. The rectangular frame (757) drives the saw blade (761) to move up and down quickly. The saw teeth (762) cut the rock wool block. The limiting of the second L-shaped plate (652) makes it difficult for the rock wool block to deviate. After the rock wool block is cut, the saw blade (761) is inserted into the interior of the C-shaped frame (655). The rock wool block will not be scattered throughout the entire cutting process.
