Description

Technical Field

[0001] The invention relates to the technical field of mineral wool production, in particular to a process system and a process for producing mineral wool by utilizing solid waste silicon-manganese slag. Background Art

[0002] Mineral wool is an inorganic fiber made of industrial slag such as slow-cooled slag from blast furnaces as the main raw material, and other materials are added through remelting and fiberization. It can be made into various products such as boards, tubes, and felts. It has many functions such as thermal insulation, heat preservation, fire prevention, corrosion resistance, moisture resistance, sound absorption, and earthquake resistance. It is widely used in construction, industrial equipment, and transportation. For example, it can be used for thermal insulation of building exterior walls, fire and sound insulation of interior walls, thermal insulation of industrial kilns and pipelines, and thermal insulation of ships. After the mineral wool is formed into a board, it needs to be cut to meet the specified size requirements.

[0003] The Chinese patent with publication number CN220762859U discloses a dust-proof mineral wool cutting machine. The structure uses the suction force of the fan to suck the dust into the dust box in the dust box through the upper dust hood and the lower dust hood for collection. At the same time, a small vacuum cleaner quickly sucks the powder at a close distance through the dust head located above the circular saw blade, thereby preventing part of the powder from flying up, further improving the dust removal effect during mineral wool cutting, preventing dust from flying and affecting the workers' vision, and improving the accuracy of processed products.

[0004] However, during the molding process, the sides of the mineral wool board are burred and uneven, and need to be trimmed manually. During the trimming and cutting process of the mineral wool board, a large amount of waste is usually generated.

[0017] S2, smelting and pulping: the mixed raw materials are heated to above 1500°C in an electric heating furnace to form a melt slurry;

[0018] S3, centrifugal cotton making: the melt slurry is input into a four-roll centrifuge through a movable flow channel, and the melt slurry is fiberized under the action of the high-speed centrifugal force of the four-roll centrifuge and the high-pressure airflow of the high-pressure fan to form mineral wool fibers;

[0019] S4, curing and molding: The mineral wool fibers are collected by a cotton collector to form a primary cotton felt, and the primary cotton felt is transported to a pendulum device by a belt conveyor. The pendulum device reciprocates to fold the primary cotton felt into multiple layers to form a secondary cotton felt, and then the secondary cotton felt is transported to a pleating molding device by a weighing conveyor to further pleat the secondary cotton felt to form a mineral wool board;

[0021] S6. Embossed packaging: The surface of the cut mineral wool board is embossed and then packaged.

[0022] The present invention has the following beneficial effects:

[0023] (1) The process system and process for producing mineral wool using solid waste silicon manganese slag generate friction between the self-driven threaded push rod and the mineral wool board waste, and with the cooperation of the mineral wool board roller conveyor, push the waste toward the frame to achieve the outward push of the waste, so as to avoid the friction between the cut mineral wool board and the waste causing damage to the edge of the mineral wool board.

[0024] (2) The process system and process for producing mineral wool using solid waste silicon manganese slag can achieve full-size cutting of mineral wool boards through the cooperation of cross-cutting blades and longitudinal cutting blades, thereby improving the practicability of the equipment. With the cooperation of horizontal guide rods and inclined guide rods, the cross-cutting blades can move synchronously with the mineral wool boards in the same direction, and the cross-cutting blades can act on the mineral wool boards to achieve cross-cutting of the mineral wool boards, thereby improving the smoothness of the cuts during cross-cutting. The slide assembly can be driven by a driving member to move in the same or opposite direction as the mineral wool boards, thereby providing power for the cross-cutting blades to cut or return, thereby reducing excess power output and reducing control difficulty and cost.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] In the description of the present invention, it is necessary to understand that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0047] On the one hand, see Figure 1 - Fig.16 The embodiment of the present invention provides a technical solution: a process system for producing mineral wool using solid waste silicon manganese slag, including a mineral wool plate roller conveyor 2 and a cutting device and a side material recovery device installed on the mineral wool plate roller conveyor 2, a frame 1 is provided on the outer side of the mineral wool plate roller conveyor 2, and a wide transmission gap 49 is formed between two rollers of the mineral wool plate roller conveyor 2.

[0048] The cutting device provided in this embodiment includes a longitudinal cutting head 24, at least two of which are provided, and the longitudinal cutting heads 24 are arranged side by side above the wide transmission gap 49, and are used to cut the mineral wool board 3 along the conveying direction of the mineral wool board roller conveyor 2. Waste is formed on both sides of the mineral wool board 3 after being cut by the longitudinal cutting heads 24. The longitudinal cutting heads 24 are mainly used for longitudinal cutting of the mineral wool board 3, so as to facilitate the division of the mineral wool board 3 into plates with smaller widths, and the longitudinal cutting heads 24 closest to the two sides of the mineral wool board 3 can be used for cutting excess material on both sides of the mineral wool board 3, which not only ensures the accuracy of the cutting size, but also can trim the side edges of the mineral wool board 3.

[0049] The edge material recovery device provided in this embodiment includes a self-driven threaded push rod 39 and a waste cutting assembly. The self-driven threaded push rod 39 is located on the upper surface of the waste, and the angle between the self-driven threaded push rod 39 and the conveying direction of the mineral wool board 3 is an obtuse angle, which is used to push the waste to the outside of the mineral wool board roller conveyor 2. In this scheme, the self-driven threaded push rod 39 rotates and generates friction with the waste of the mineral wool board 3. With the cooperation of the mineral wool board roller conveyor 2, the waste is pushed toward the frame 1 to realize the outward push of the waste, so as to avoid friction between the cut mineral wool board 3 and the waste, which may cause damage to the edge of the mineral wool board 3.

[0050] The waste cutting assembly provided in this embodiment is arranged on both sides of the mineral wool board roller conveyor 2, and is used to shred the waste in the axial direction of the roller, so that the shredded waste falls through the wide transmission gap 49, thereby separating the waste from the mineral wool board 3.

[0051] like Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, in order to achieve the shredding of waste materials so that the waste materials can fall through the wide transmission gap 49, the waste cutting assembly provided in this embodiment includes waste cutting knives 46 arranged on both sides of the mineral wool board roller conveyor 2 and a driving structure arranged on both sides of the mineral wool board roller conveyor 2, and the driving structure is used to drive the waste cutting knives 46 to slide back and forth along the axial direction of the roller to shred the waste materials along the axial direction of the roller.

[0052] The driving structure includes a guide groove arranged on the frame 1, a waste cutting knife 46 is slidably connected with the guide groove, and a connecting rod 45 is rotatably installed at one end of the waste cutting knife 46, a transmission shaft 40 is rotatably installed on the outer side of the frame 1, the transmission shaft 40 is fixedly connected with one of the roller axes, and a worm 42 is installed at the other end of the transmission shaft 40, a rotating shaft 41 is rotatably installed on the outer side of the frame 1, a worm wheel 43 meshing with the worm 42 is installed on the rotating shaft 41, and a movable frame 44 is fixed at the other end of the rotating shaft 41, a sliding block is slidably connected on the movable frame 44, and the connecting slider is rotatably connected with the other end of the connecting rod 45, and an adjusting bolt is rotatably installed inside the movable frame 44, and the adjusting bolt is rotatably installed inside the movable frame 44. The joint bolt is threadedly connected to the connecting slider. By turning the adjusting bolt and the threaded connection between the adjusting bolt and the connecting slider, the position of the connecting slider in the movable frame 44 can be achieved, which is conducive to adjusting the pushing distance of the waste cutting knife 46 so that the waste cutting knife 46 can adapt to the cutting of wastes of different widths. Specifically, during use, the transmission shaft 40 is driven to rotate by the roller, and then the worm 42 drives the worm wheel 43 to rotate, and the rotating shaft 41 is rotated through the worm wheel 43, so that the movable frame 44 is rotated, and the connecting rod 45 is swung through the movable frame 44, thereby pushing the waste cutting knife 46 to move back and forth to achieve waste shredding.

[0053] like Figure 3 , Figure 4 and Figure 8 As shown, the cutting device provided in this embodiment also includes a measuring roller 16 and a pressing roller 17. The measuring roller 16 is arranged upstream of the wide transmission gap 49, and the measuring roller 16 is against the mineral wool board 3, and is used to measure the cutting length of the mineral wool board 3. The pressing roller 17 is rotatably installed downstream of the wide transmission gap 49, and the pressing roller 17 is against the mineral wool board 3, so that the outer surface of the pressing roller 17 and the mineral wool board 3 have the same linear speed.

[0054] The mineral wool board roller conveyor 2 cooperates with the pressing roller 17 and the measuring roller 16 to clamp the mineral wool board 3 , thereby improving the stability of the mineral wool board 3 and facilitating the longitudinal cutting of the mineral wool board 3 .

[0055] like Figure 7 As shown, in order to further improve the effect of stripping waste from the mineral wool board 3 and the stability of waste cutting, the edge material recovery device provided in this embodiment also includes a guide block 11. The guide block 11 is arranged in the gap between the mineral wool board 3 and the waste, and is mainly used to limit the waste after stripping to prevent the waste from rebounding. The side of the guide block 11 facing the mineral wool board 3 is a vertical surface structure, and the vertical surface structure can reduce the damage to the mineral wool board 3, and the side of the guide block 11 facing the waste is a slope structure, and the slope structure cooperates with the waste cutting knife 46 to withstand the thrust of the waste cutting knife 46 when shredding the waste, thereby making the cutting of the waste cutting knife 46 more stable.

[0056] like Figure 4 , Figure 8, Fig. 9 , Fig.10 and Fig.11 As shown, in order to avoid waste accumulation, the edge material recovery device provided in this embodiment also includes a first sleeve 10, which is axially slidable along the roller and is arranged on the outside of the pressure roller 17 near the waste. Preferably, a guide rail 32 is provided on the outside of the pressure roller 17 in sliding connection with the first sleeve 10, and a locking bolt can be provided on the first sleeve 10. This type of structure is widely used in the prior art and will not be described in detail here. It is mainly used for locking the first sleeve 10 after sliding. In addition, a push block 19 is installed on the first sleeve 10. The rotation of the pressure roller 17 causes the first sleeve 10 to drive the push block 19 to push the waste to fall, thereby accelerating the waste to fall from the wide transmission gap 49 to avoid waste accumulation.

[0057] In order to collect waste, the edge material recovery device provided in this embodiment also includes a waste trough 47, which is arranged at the bottom of the mineral wool board roller conveyor 2, and is used to receive the waste generated when the mineral wool board 3 is cut.

It should be noted that the angle located upstream of the mineral wool board roller conveyor 2 is an acute angle.

[0059] The cutting device provided in this embodiment also includes a horizontal guide rod 13, which is arranged above the mineral wool board roller conveyor 2, and the horizontal guide rod 13 and the oblique guide rod 12 are not on the same horizontal plane to prevent the horizontal guide rod 13 and the oblique guide rod 12 from interfering with each other. The horizontal guide rod 13 is perpendicular to the conveying direction of the mineral wool board 3, and the horizontal guide rod 13 can move in the same direction or in the opposite direction along the conveying direction of the mineral wool board roller conveyor 2. The orthographic projections of the oblique guide rod 12 and the horizontal guide rod 13 in the plane have an intersection, and the intersection changes position continuously with the movement of the horizontal guide rod 13. A moving seat 14 is provided at the intersection position, and the moving seat 14 can slide on both the oblique guide rod 12 and the horizontal guide rod 13, and a cross-cutting knife head 18 is installed at the lower end of the moving seat 14.

[0060] Among them, when the horizontal guide rod 13 is in the same direction as the conveying direction of the mineral wool board roller conveyor 2, the horizontal guide rod 13 pushes the movable seat 14 to slide on the inclined guide rod 12, so that the cross-cutting head 18 acts on the mineral wool board 3 to achieve cross-cutting of the mineral wool board 3. When the horizontal guide rod 13 is in the opposite direction to the conveying direction of the mineral wool board roller conveyor 2, the horizontal guide rod 13 pushes the movable seat 14 to slide on the inclined guide rod 12, so that the cross-cutting head 18 returns to the upstream of the mineral wool board roller conveyor 2.

[0061] like Figure 3 , Figure 4 , Figure 8 , Fig.10 , Fig.12 and Fig.13 As shown, the cutting device provided in this embodiment further includes a side bracket 5 , which is disposed at both ends above the wide transmission gap 49 , and the side bracket 5 is rotatably connected to the measuring roller 16 and the pressure roller 17 .

[0062] To facilitate the adjustment of the longitudinal cutting specifications of the mineral wool board 3, the cutting device provided in this embodiment also includes a guide rod 21 and a screw rod 20. The guide rod 21 is fixed between the two side brackets 5, and the screw rod 20 is fixed between the two side brackets 5, and the screw rod 20 is located below the guide rod 21.

[0063] Among them, an adjustment slide 22 adapted to the longitudinal cutting head 24 is provided on the outside of the screw rod 20. It should be noted that the adjustment slide 22 located at both ends of the screw rod 20 is installed with a connecting bracket 9, the connecting bracket 9 is fixedly connected to the guide block 11, and the connecting bracket 9 is rotatably connected to the self-driving threaded push rod 39. A second sliding sleeve 25 slidably connected to the guide rod 21 is provided on the adjustment slide 22, and a threaded sleeve 23 threadedly connected to the screw rod 20 is rotatably installed in the adjustment slide 22, and one end of the threaded sleeve 23 passes through the adjustment slide 22. The knob is turned, and preferably a scale line is set on the outside of the guide rod 21 to measure the distance between two adjacent adjustment slides 22, so as to adjust the distance between two adjacent longitudinal cutting heads 24, and then adjust the size of the longitudinal cutting. Preferably, the cross-cutting head 18 and the longitudinal cutting head 24 are both laser cutting knives or water jets. When the cross-cutting head 18 and the longitudinal cutting head 24 are water jets, a filter screen plate 48 can be optionally installed inside the waste trough 47 for filtering and collecting waste water, and a drain valve can also be installed at the bottom of the waste trough 47 for discharging waste water.

[0064] In this solution, the rotation of the threaded sleeve 23 is controlled by turning the knob, and the threaded sleeve 23 is threadedly connected to the screw rod 20. Under the sliding connection between the guide rod 21 and the second sleeve 25, the threaded sleeve 23 can drive the adjustment slide 22 to move on the screw rod 20, thereby adjusting the distance between two adjacent adjustment slides 22, further adjusting the distance between two adjacent longitudinal cutting heads 24, and then adjusting the size of the longitudinal cutting.

A horizontal portion is formed on the upper side of a synchronous transmission belt 29, and the outer diameters of the first driven wheel 27 and the second driven wheel 28 are the same as the first driving wheel 26 to ensure that the linear speed of the first synchronous transmission belt 29 is the same as the conveying speed of the mineral wool board 3. The slide assembly 15 can clamp or loosen the upper horizontal portion of the first synchronous transmission belt 29. Preferably, the first synchronous transmission belt 29 has very little or no deformation ability to stably drive the slide assembly 15 to move, and a first tensioning roller is installed on the outer side of the supporting beam 7 to maintain the tension of the first synchronous transmission belt 29.

[0068] The reverse drive provided in this embodiment includes a third driven wheel 34 arranged at one end of the inner side of the U-shaped connecting frame 8 and a second driving wheel 35 arranged at the other end of the inner side of the U-shaped connecting frame 8. A cavity is provided on the inner side of the U-shaped connecting frame 8 for accommodating the third driven wheel 34 and the second driving wheel 35. A second synchronous transmission belt 31 is provided between the third driven wheel 34 and the second driving wheel 35. Notches are provided at relative positions of the two cavities for the movement of the second synchronous transmission belt 31. The slide assembly 15 can clamp or loosen the lower side of the second synchronous transmission belt 31. Preferably, the second synchronous transmission belt 31 has very little or no deformation ability to stably drive the slide assembly 15 to move, and a second tensioning roller is installed on the inner side of the U-shaped connecting frame 8 for maintaining the tension state of the second synchronous transmission belt 31.

[0069] It should be noted that the slide assembly 15 is connected to the second synchronous transmission belt 31 or the first synchronous transmission belt 29 separately, that is, the slide assembly 15 can only be clamped with one of the second synchronous transmission belt 31 or the first synchronous transmission belt 29 at the same time, and an acceleration gear box 33 is installed on the inner side of one side of the support beam 7, and the input end of the acceleration gear box 33 is connected to the second driven wheel 28, and the output end of the acceleration gear box 33 is connected to the second driving wheel 35, so that the second driven wheel 28 and the second driving wheel 35 rotate in the same direction, and the linear speed of the second synchronous transmission belt 31 is increased. The speed is at least twice the linear speed of the first synchronous transmission belt 29. During the cutting process of the mineral wool board 3, the mineral wool board 3 is in motion, and the horizontal speed of the cross-cutting head 18 in this process is synchronized with the mineral wool board 3. Therefore, when the cross-cutting head 18 returns, its reverse movement speed must be at least greater than the movement speed of the mineral wool board 3. In order to cut smaller-sized mineral wool boards 3, it is necessary to control the return speed of the cross-cutting head 18 to be faster. Therefore, the optional acceleration gearbox 33 is an adjustable gearbox to better control the return speed of the cross-cutting head 18.

[0070] like Fig.12 - Fig.16 As shown, the slide assembly 15 provided in this embodiment includes a slide 151 arranged on one side of the C-shaped connecting frame 8, and a limiting slider 152 is provided on the side of the slide 151 facing the C-shaped connecting frame 8. The limiting slider 152 is slidably connected to the first through groove 30 to ensure that the slide assembly 15 can slide in the first through groove 30.

[0071] In addition, a fixed seat 154 is fixed at the lower end of the slide 151, and a first pressure plate 155 is provided at the upper end of the fixed seat 154 on the side facing the second synchronous transmission belt 31. Preferably, the first pressure plate 155 is provided with a first anti-slip tooth on the side facing the second synchronous transmission belt 31 to improve the stability of the connection between the slide assembly 15 and the second synchronous transmission belt 31, and a second pressure plate 156 is provided at the lower end of the fixed seat 154 on the side facing the first synchronous transmission belt 29. Preferably, the second pressure plate 156 is provided with a second anti-slip tooth on the side facing the first synchronous transmission belt 29 to improve the stability when the slide assembly 15 is connected to the first synchronous transmission belt 29. In addition, a second through groove 157 is opened on the inner side of the fixed seat 154, and a third pressure plate 158 is slidably installed inside the second through groove 157. A cylinder 153 for driving the third pressure plate 158 to rise and fall in the second through groove 157 is fixed in the slide 151.

[0072] When the third pressing plate 158 is located in the middle of the second through slot 157, the slide assembly 15 is not in contact with the second synchronous transmission belt 31 and the first synchronous transmission belt 29. When the third pressing plate 158 is located at the upper end of the second through slot 157, the slide assembly 15 clamps the second synchronous transmission belt 31 to drive the slide assembly 15 and the mineral wool board 3 to move toward each other. When the third pressing plate 158 is located at the lower end of the second through slot 157, the slide assembly 15 clamps the first synchronous transmission belt 29 to drive the slide assembly 15 and the mineral wool board 3 to move in the same direction. In order to realize the automatic control of the cylinder 153, contact switch male heads 37 electrically connected to the cylinder 153 are provided on both sides of the limit slider 152, and a first contact switch female head 36 adapted to the contact switch male head 37 is installed at one end of the first through slot 30, and a second contact switch female head 38 adapted to the contact switch male head 37 is provided at the other end of the first through slot 30.

[0073] When the contact switch male head 37 contacts the first contact switch female head 36 to control the cylinder 153 to move the third pressing plate 158 to the middle section of the second through slot 157, at this time, the slide assembly 15 is not in contact with the second synchronous transmission belt 31 and the first synchronous transmission belt 29, and the slide assembly 15 is in a preparatory state before cutting. When the contact switch male head 37 contacts the second contact switch female head 38 to control the cylinder 153 to move the third pressing plate 158 to the upper end of the second through slot 157, at this time, The slide assembly 15 clamps the second synchronous transmission belt 31 to drive the slide assembly 15 and the mineral wool board 3 to move toward each other, thereby realizing the return stroke of the slide assembly 15. The measuring roller 16 is electrically connected to the cylinder 153. When the length measured by the measuring roller 16 meets the requirement, the cylinder 153 is controlled to move the third pressure plate 158 to the lower end of the second through groove 157. At this time, the slide assembly 15 clamps the first synchronous transmission belt 29 to drive the slide assembly 15 and the mineral wool board 3 to move in the same direction, thereby realizing the cross-cutting of the mineral wool board 3.

[0074] like Figure 1As shown, the process system for producing mineral wool using solid waste silicon manganese slag provided in this embodiment also includes a raw material preparation device, a molding device, a curing and drying device, an embossing and packaging device, and a waste gas treatment device. This process device is a prior art and will not be repeated here. The waste gas treatment device is used to purify the waste gas generated by the molding device and the curing and drying device. The molding device includes a centrifugal fiberizing machine, a cotton collecting machine, a pendulum structure, and a pleated molding structure in sequence. A high-pressure fan and a cooling water circulation device are provided on the side of the centrifugal fiberizing machine. The high-pressure fan can fiberize the raw material. The cooling water circulation device is used to cool the raw material after it is formed into cotton. Preferably, the centrifugal fiberizing machine is a four-roller centrifuge to increase production capacity.

[0075] When in use (working), the height of the supporting beam 7 is adjusted. After the mineral wool board 3 moves to the measuring roller 16 and the pressing roller 17, friction is generated between the measuring roller 16, the pressing roller 17 and the mineral wool board 3, so that the outer surfaces of the measuring roller 16 and the pressing roller 17 have the same linear speed as the mineral wool board 3. The threaded sleeve 23 is controlled to rotate by turning the knob. The threaded sleeve 23 is threadedly connected to the screw rod 20. Under the sliding connection between the guide rod 21 and the second sliding sleeve 25, the threaded sleeve 23 can drive the adjusting slide 22 to move on the screw rod 20, thereby adjusting the distance between two adjacent adjusting slides 22, further adjusting the distance between two adjacent longitudinal cutting heads 24, and then adjusting the size of the longitudinal cutting. In addition, under the squeezing of the measuring roller 16 and the pressing roller 17, the mineral wool board 3 can be prevented from shaking during longitudinal cutting, thereby improving the stability of the mineral wool board 3 during longitudinal cutting.

[0076] In this process, the longitudinal cutting blade 24 closest to the two sides of the mineral wool board 3 can be used to cut the excess material on both sides of the mineral wool board 3, which not only ensures the accuracy of the cutting size, but also can trim the side of the mineral wool board 3. The self-driven threaded push rod 39 rotates and generates friction with the waste of the mineral wool board 3. With the cooperation of the mineral wool board roller conveyor 2, the waste is pushed toward the frame 1 to realize the outward push of the waste, so as to avoid the friction between the cut mineral wool board 3 and the waste, which may cause damage to the edge of the mineral wool board 3. The transmission shaft 4 is driven by the roller to 0 rotates, and then the worm 42 drives the worm wheel 43 to rotate, and the worm wheel 43 rotates the rotating shaft 41, so that the movable frame 44 rotates, and the connecting rod 45 swings through the movable frame 44, thereby pushing the waste cutting knife 46 to move back and forth, so as to realize the shredding of the waste, and the first sliding sleeve 10 drives the pushing block 19 to push the waste to fall, thereby accelerating the waste to fall from the wide transmission gap 49, avoiding the accumulation of waste, and making the waste fall into the waste trough 47, so as to realize the collection of waste, which is beneficial to the recycling of waste.

[0077] After the longitudinal cutting of the mineral wool board 3 is completed, when the measuring roller 16 detects the transverse cutting length, the control cylinder 153 moves the third pressing plate 158 to the lower end of the second through groove 157, so that the third pressing plate 158 cooperates with the second pressing plate 156 to clamp the first synchronous transmission belt 29, and the first driving wheel 26 is driven to rotate through the pressing roller 17. Through the transmission between the first driving wheel 26, the first driven wheel 27, the second driven wheel 28 and the first synchronous transmission belt 29, the first synchronous transmission belt 29 moves at the same speed as the mineral wool board 3. The first synchronous transmission belt 29 is driven by the second driven wheel 28, thereby causing the second driven wheel 35 to rotate. The second driven wheel 35 and the third driven wheel 36 are driven by the second driven wheel 28. The second driven wheel 35 and the third driven wheel 36 are driven by the second driven wheel 28, thereby causing the second driven wheel 35 to rotate. The transmission action between the wheel 34 and the second synchronous transmission belt 31 causes the lower side of the second synchronous transmission belt 31 to move in the opposite direction to the mineral wool board 3. After the cross-cutting is completed, the contact switch male head 37 contacts the second contact switch female head 38 to control the cylinder 153 to move the third pressing plate 158 to the upper end of the second through groove 157. At this time, the third pressing plate 158 cooperates with the first pressing plate 155 to clamp the lower side of the second synchronous transmission belt 31, so that the slide assembly 15 moves along with the lower side of the second synchronous transmission belt 31 to drive the slide assembly 1 5 moves towards the mineral wool board 3 to realize the return of the slide assembly 15, thereby realizing the return of the cross-cutting knife head 18. After the cross-cutting knife head 18 returns, the contact switch male head 37 contacts with the first contact switch female head 36 to control the cylinder 153 to move the third pressure plate 158 to the middle section inside the second through groove 157. At this time, the slide assembly 15 is not in contact with the second synchronous transmission belt 31 and the first synchronous transmission belt 29, and the slide assembly 15 is in a pre-cutting preparation state. At this time, the cross-cutting knife head 18 does not move to prepare for cutting.
