Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cutting equipment, in particular to a heat insulation board forming and cutting machine for external wall. BACKGROUND

[0002] The external wall insulation board, also known as a horizon building external wall decoration integrated board, is composed of polymer mortar, glass fiber mesh cloth, flame-retardant molded polystyrene foam board (EPS) or extruded board (XPS), and the like, and has the functions of heat preservation, heat insulation, and flame retardation.

[0003] In the prior art, the formed external wall insulation board needs to be cut into a corresponding size according to the size during the production of the external wall insulation board. In the actual cutting process, the cutting equipment blade contacts the external wall insulation board. When the cutting pressure applied on the insulation board exceeds the bearing range of the board, the edge of the board is subjected to excessive extrusion force, which can crush the edge material or cause plastic deformation, and further cause edge collapse. In addition, when the cutting speed is too fast, the contact time between the cutter and the external wall insulation board is extremely short, and the impact force generated instantaneously is large. The large impact force can damage the material at the edge of the board before it deforms, thereby causing edge collapse.

[0004] The heat preservation principle of the external wall insulation board is to use the material with low thermal conductivity to block heat transfer. When the edge collapse occurs, the heat preservation layer at the edge of the board is damaged, and the base material (such as a concrete wall, a brick wall, etc.) with high thermal conductivity is exposed. This is like forming a thermal bridge in the heat preservation system, and heat will be quickly transferred through the exposed edge, reducing the heat preservation effect of the entire external wall insulation system. In addition to the edge collapse, the surface of the insulation board can also have cracks, depressions, and other defects during the edge collapse process.

[0005] To solve the above problems, the present application provides a heat insulation board forming and cutting machine for external wall. SUMMARY

[0023] Beneficial effects

[0024] Compared with the prior art, the present invention provides a forming and cutting machine for thermal insulation boards for exterior walls, which has the following advantages:

[0025] By using rollers, buffer springs, and push rods, uniform pressure is applied to the upper surface of the exterior wall insulation board around the cutting position during the cutting process. During cutting, the action of the cutting machine will cause local stress on the board. The uniform pressure distribution can make the internal stress of the board uniform, avoiding problems such as chipping and missing corners at the edges of the exterior wall insulation board. At the same time, uniform pressure helps to maintain the dimensional stability of the insulation board during the cutting process, preventing the exterior wall insulation board from bending, deforming, and chipping during the cutting process, which would lead to inaccurate cut dimensions.

[0026] By setting up connecting plates and rigid connecting rods, when one end of the roller moves upward under the extrusion force, it simultaneously drives the other end of the roller to move upward, keeping the rollers at both ends of the positioning plate in the same horizontal plane. When the bottom surface of the roller contacts the external wall insulation board and generates extrusion force, if the rollers at both ends are in the same horizontal plane, the extrusion force can be more evenly distributed on the two rollers. This can avoid a single roller bearing too large a load, and at the same time make the pressure applied by the rollers at both ends on the external wall insulation board more balanced, reduce stress concentration, and avoid damage to the external wall insulation board caused by unstable extrusion force.

[0027] By using sliders and connecting rods, the connecting plate and rigid connecting rod can be kept to have the same displacement distance in the vertical direction. In addition, sliders and connecting rods can approximate the reinforcing ribs of the rigid connecting rod, increasing the structural rigidity of the rigid connecting rod. Furthermore, the slider, connecting rod, and rigid connecting rod as a whole form a triangular structure, which has stronger stability. This ensures the stability of the force on the rigid connecting rod when it moves in the vertical direction, and further ensures that the positioning rods at both ends of the rigid connecting rod move upward synchronously. This avoids the uneven pressure applied by the rollers to the external wall insulation board, which could cause chipping during the cutting of the external wall insulation board.

[0028] By setting up a separator, the cut but not completely cut exterior wall insulation board is separated according to the cutting marks. In conjunction with the existing exterior wall insulation board limiting device, the cut part of the exterior wall insulation board is repositioned. During the cutting process of exterior wall insulation board, the board cannot be completely cut in one go due to various reasons. Using a separator can accurately separate the incompletely cut board along the predetermined cutting marks, avoiding problems such as edge damage, cracking or burrs caused by secondary cutting or forcibly breaking it apart. This ensures a neat and smooth cut surface and improves cutting accuracy.

[0029] By using a reciprocating grinding disc, the edges of the cut surfaces of the exterior wall insulation board can be ground after cutting, thus smoothing the cut surfaces. The grinding process can precisely shape the lines of the cut surface edges, turning them from obtuse angles into clear and neat right angles. The grinding operation is completed simultaneously during the cutting process, which can avoid grinding during the subsequent use of the exterior wall insulation board. In addition, the smooth cut surface after grinding can reduce the possibility of workers being scratched by the rough surface during subsequent handling.

[0030] By using rollers, buffer springs, and partitions, the pressure on the external wall insulation board can be kept stable before, during, and after cutting. This further avoids stress concentration inside the external wall insulation board during the cutting process. A stable pressure environment helps the stress inside the external wall insulation board to be released and distributed evenly, reducing problems such as edge chipping, cracking, and deformation caused by stress concentration.

[0031] By using wedge one, wedge two, and the squeezing rod, the direction of the vacuum cleaner's suction port is changed, and this direction is always opposite to the forward direction of the grinding disc. When the suction port is tilted in the opposite direction to the forward direction of the grinding disc, it can better guide the airflow. Dust generated during grinding will fly forward as the grinding disc rotates, and the reverse-tilted suction port can directly target the dust's diffusion path. This design acts like an "interception channel" for the dust, making it easier for it to enter the suction port. When grinding the cut surface of exterior wall insulation panels, dust will fly out along the tangent of the grinding disc; the reverse-tilted suction port can promptly suck in this dust, reducing the dust's residence time and diffusion range in the air.

[0068] The overall working process and principle of the above embodiments are as follows:

[0069] Preparation:

[0070] The worker places the exterior wall insulation board to be cut on the main frame 11 of the cutting device. Then, the edge of the exterior wall insulation board is restricted by the limiting device of the existing equipment to prevent the position of the exterior wall insulation board from shifting during the cutting process. Then, the worker starts the drive motor 15. Since one of the rollers 16 is fixedly connected to the output shaft of the drive motor 15 through a synchronous belt, and the two rollers 16 are connected by a transmission belt 17, the start of the drive motor 15 will drive the two rollers 16 to rotate synchronously, and transport the exterior wall insulation board to be cut on the main frame 11 of the cutting device to the cutting machine 14 to cut the exterior wall insulation board.

[0071] It should be noted that the limiting device set on the main frame 11 of the cutting device is an existing device, so it will not be described in detail here.

[0072] Cutting of exterior wall insulation panels:

[0073] When the external wall insulation board is transported to the cutting machine 14, the cutting machine 14 cuts the external wall insulation board according to the predetermined size. During the process of transporting the external wall insulation board to the cutting machine 14, one end of the external wall insulation board will contact the roller 29 on one side. The surface of one side of the external wall insulation board will contact the circumferential surface of the roller 29. The circumferential surface of the roller 29 will be contacted by the top surface of the side wall of the external wall insulation board and will be subjected to pressure from the side wall of the external wall insulation board. As a result, the roller 29 will move upward in the vertical direction. Then the entire external wall insulation board will enter under the roller 29. As the cutting machine 14 cuts the external wall insulation board, the roller 29 on the other side of the positioning plate 22 will also contact the side of the external wall insulation board and abut against the top surface of the external wall insulation board.

[0074] During the above process, the roller 29 moves upward under force, which will simultaneously drive the positioning block 27 to move upward. Since the top of the positioning block 27 is fixedly connected to the push rod 23, and the push rod 23 is slidably connected inside the positioning plate 22, the upward movement of the positioning block 27 will drive the push rod 23 and the connecting plate 24 fixedly connected to the top of the push rod 23 to move upward. During the upward movement of the positioning block 27, the buffer spring 28 set between the positioning block 27 and the positioning plate 22 will also be compressed.

[0075] Since the upper surface of the positioning plate 22 is fixedly connected to the cylindrical guide rail 25, and the connecting plate 24 is slidably connected to the outer surface of the cylindrical guide rail 25, the cylindrical guide rail 25 is used to limit the position and movement trajectory of the connecting plate 24, so as to ensure the accuracy of the vertical displacement of the connecting plate 24 in the vertical direction.

[0076] In addition, during the above process, the rigid connecting rod 26, which is symmetrically fixed between the two connecting plates 24, will move upward. When one of the connecting plates 24 moves upward, it will drive the other connecting plate 24 to move upward through the rigid connecting rod 26. During the upward movement of the connecting plate 24, the push rod 23 at the bottom of the connecting plate 24 will move upward simultaneously, and the positioning block 27 connected to the push rod 23 will move upward, and the roller 29 connected to the positioning block 27 will move upward.

[0077] Therefore, during the cutting process of the exterior wall insulation board, the cooperation between the roller 29 and the buffer spring 28 will apply a uniform downward pressure around the cutting position of the exterior wall insulation board. At the same time, the roller 29 cooperates with the exterior wall insulation board in a moving state. The roller 29 rotates due to the friction of the outer surface of the exterior wall insulation board, sharing part of the vertical pressure applied by the roller 29 to the exterior wall insulation board and reducing the stress concentration at the contact surface between the two.

[0078] With the rollers 29, buffer springs 28 and push rods 23, uniform pressure is applied to the upper surface of the external wall insulation board around the cutting position during the cutting process. During cutting, the action of the cutting machine 14 will cause the board to be subjected to local stress. The uniform pressure distribution can make the internal stress of the board uniform, avoiding problems such as chipping and missing corners at the edges of the external wall insulation board. At the same time, uniform pressure helps to maintain the dimensional stability of the insulation board during the cutting process, and avoids bending and deformation of the external wall insulation board during the cutting process, which would lead to inaccurate cutting dimensions.

[0079] With the connection plate 24 and rigid connecting rod 26, as one end roller 29 moves upward under the extrusion force, it simultaneously drives the other end roller 29 to move upward, keeping the rollers 29 at both ends of the positioning plate 22 in the same horizontal plane. When the bottom surface of the roller 29 contacts the external wall insulation board and generates extrusion force, if the rollers 29 at both ends are in the same horizontal plane, the extrusion force can be more evenly distributed on the two rollers 29. This can avoid a single roller 29 bearing too large a load, and at the same time make the pressure applied by the rollers 29 at both ends on the external wall insulation board more balanced, reduce stress concentration, and avoid damage to the external wall insulation board caused by unstable extrusion force.

[0080] Further stabilization of pressure on roller 29:

[0081] During the upward movement of the rigid connecting rod 26, the slider 31, which is symmetrically slidably connected to the outer surface of the rigid connecting rod 26, will move upward synchronously. In addition, the gear 36, which is rotatably connected to the outer surface of the rigid connecting rod 26, will move upward synchronously. Through the meshing of the gear 36 and the toothed plate 37, the gear 36 will rotate synchronously during the upward movement.

[0082] During the above process, as the slider 31 moves vertically, the connecting rod 32, which is rotatably connected to the outer surface of the slider 31, will move accordingly. Since the end of the connecting rod 32 away from the slider 31 has a groove 33, and the symmetrically arranged connecting rods 32 intersect within the groove 33, a positioning rod 34 is slidably connected to it. The positioning rod 34 is fixedly connected to the outer surface of the annular limiting block 35, and the annular limiting block 35 is fixedly connected to the outer surface of the cylindrical positioning rod 21. Therefore, as the connecting rod 32 moves, the distance between the connecting rod 32 and the end connected to the slider 31 and the cylindrical positioning rod 21 gradually shortens. Consequently, the positioning rod 34 will slide within the groove 33. During this sliding process, the slider 31 connected to the two intersecting connecting rods 32 is forced to displace on the rigid connecting rod 26. The displacement direction is towards the connecting plate 24 (see details). Figure 4 );

[0083] Simultaneously, the sliders 31 and connecting rods 32, which are set on both sides of the same cylindrical positioning rod 21, will produce the same movement, so they will not be described in detail here. Through the setting of sliders 31 and connecting rods 32, the connecting plate 24 and rigid connecting rod 26 can be kept to produce the same displacement distance in the vertical direction. In addition, sliders 31 and connecting rods 32 can approximate the reinforcing ribs of rigid connecting rod 26, increasing the structural rigidity of rigid connecting rod 26. Moreover, sliders 31, connecting rods 32 and rigid connecting rod 26 as a whole form a triangular structure, which has stronger stability. When rigid connecting rod 26 moves in the vertical direction, it can ensure the stability of the force on rigid connecting rod 26, and further make the positioning rods 34 at both ends of rigid connecting rod 26 move upward synchronously, thereby avoiding the unbalanced pressure applied by rollers 29 on the external wall insulation board, which would cause chipping during the cutting of external wall insulation board.

[0084] Treatment of the cut surfaces of the exterior wall insulation boards after cutting:

[0085] The exterior wall insulation board cut by the cutting machine 14 will be in a state where one part is cut and the other part is not cut. That is, the exterior wall insulation board is divided into two parts. The two parts of the exterior wall insulation board are supported only by the material strength of the exterior wall insulation board itself. A gap will appear between the cut exterior wall insulation board parts, and the gap will gradually come into contact with the partition plate 42.

[0086] In the above process, since the partition plate 42 is set in the middle of the positioning frame 41 and the size of the positioning frame 41 is compatible with the main frame 11 of the cutting device, the position of the cut exterior wall insulation board is re-fixed under the cooperation of the limiting device and the partition plate 42 on the main frame 11 of the cutting device, so as to avoid the situation where the cut exterior wall insulation board is only subjected to the clamping force of the limiting device, causing the cutting position to shift.

[0087] Furthermore, during the process of the partition plate 42 contacting the cut exterior wall insulation board, the staff starts the external motor. Since the output shaft of the external motor is fixedly connected to one end of the threaded rod 43 that passes through the positioning frame 41, the operation of the external motor will cause the threaded rod 43 to rotate inside the positioning frame 41. As the threaded rod 43 rotates, the moving block 44, which is threaded to the outer surface of the threaded rod 43, will move horizontally back and forth on the threaded rod 43.

[0088] It should be noted that the movable block 44 is equipped with balls inside. The movable block 44 is slidably connected to the threaded groove on the outer surface of the threaded rod 43 through the internally provided balls. The movable block 44 and the threaded rod 43 together constitute a ball screw. Specifically, the continuous rotation of the threaded rod 43 can drive the movable block 44 to perform horizontal reciprocating motion on the outer surface of the threaded rod 43.

[0089] During the above movement, since the other end of the positioning frame 41 is fixedly connected to the limiting rod 45, the limiting rod 45 is slidably connected to the moving block 46, and the moving block 44 and the moving block 46 are fixedly connected to the round rod 47, and the two round rods 47 arranged in the vertical direction both penetrate the partition plate 42, the moving block 44 will drive the moving block 46 to move simultaneously on the limiting rod 45 through the round rod 47 when it moves.

[0090] In addition, as the round rod 47 moves, the grinding discs 48, which are fixedly connected to the surface of the round rod 47 and set on both sides of the partition plate 42, will move synchronously to grind the surface of the cut exterior wall insulation board. It should be noted that the grinding discs 48 are attached to the surface of the partition plate 42, and the side of the grinding discs 48 away from the partition plate 42 contacts the cut surface of the cut exterior wall insulation board. As the grinding discs 48 continue to contact it, the cut surface of the exterior wall insulation board is ground smooth.

[0091] By setting the partition plate 42, the cut but not completely cut exterior wall insulation board is separated according to the cutting marks. In conjunction with the existing exterior wall insulation board limiting device, the cut part of the exterior wall insulation board is repositioned. During the cutting process of exterior wall insulation board, the board cannot be completely cut at one time due to various reasons. Using the partition plate 42, the incompletely cut board can be accurately separated along the predetermined cutting marks, avoiding problems such as damage, cracking or burrs on the edge of the board due to secondary cutting or forcibly breaking it open. This ensures the neatness and smoothness of the cut surface and improves the cutting accuracy.

[0092] With the reciprocating grinding disc 48, the edges of the cut surface of the exterior wall insulation board can be ground after cutting, thus smoothing the cut surface. The grinding process can precisely shape the lines of the cut surface edge, turning it from an obtuse angle into a clear and neat right angle. The grinding operation is completed simultaneously during the cutting process, which can avoid grinding during the subsequent use of the exterior wall insulation board. In addition, the smooth cut surface after grinding can reduce the possibility of being scratched by the rough surface during subsequent handling by workers.

[0093] By setting up rollers 29, buffer springs 28 and partition plates 42, the pressure on the external wall insulation board before, during and after cutting can be kept stable, further avoiding stress concentration inside the external wall insulation board during the cutting process. The stable pressure environment helps the stress inside the external wall insulation board to be released and distributed evenly, reducing problems such as edge chipping, cracking and deformation caused by stress concentration.

[0094] Grinding debris handling:

[0095] During the reciprocating motion of the two round rods 47, wedge 1 51 is rotatably connected to the outer surface of the upper round rod 47, and wedge 2 52 is rotatably connected to the outer surface of the lower round rod 47. A pin is fixedly connected to the outer surface of wedge 2 52, and wedge 2 52 is slidably connected to the through groove of wedge 1 51 through the pin. Therefore, as the two round rods 47 move, wedge 1 51 and wedge 2 52 will reciprocate synchronously. At the same time, the vacuum cleaner 54 fixedly installed at the bottom of wedge 2 52 will reciprocate accordingly, absorbing the debris generated when the grinding disc 48 grinds the cut surface of the exterior wall insulation board, and transporting it to the external debris storage device through the dust conveying pipe 55 connected to the vacuum cleaner 54.

[0096] It should be noted that wedge 1 51 and wedge 2 52 are connected at an obtuse angle with the pin fixed on wedge 2 52 as the fulcrum. When wedge 1 51 and wedge 2 52 move toward the drive motor 15, the apex angle formed between wedge 1 51 and wedge 2 52 is in the direction toward the drive motor 15 (see reference for details). Figure 5 and Figure 6 );

[0097] During the movement of wedge 1 51 and wedge 2 52 (this refers to the movement towards drive motor 15, see details below), please refer to the above description. Figure 5 and Figure 6 Since both ends of the positioning frame 41 are fixedly connected with the pressing rod 56, the movement of wedge 1 51 and wedge 2 52 will contact the pressing rod 56 located in the end of the positioning frame 41 near the drive motor 15. The apex formed by wedge 1 51 and wedge 2 52 abuts against the pressing rod 56. Since the position of the pressing rod 56 is fixed, wedge 1 51 and wedge 2 52 are pressed by the pressing rod 56. The pin on wedge 2 52 will move with its connection point with wedge 1 51 as the fulcrum. During the movement of the pin, the connecting spring 53 located between wedge 1 51 and the pin is compressed.

[0098] In this state, wedge 1 51 and wedge 2 52 will rotate synchronously around their connection point with the round rod 47 as the fulcrum. Specifically, the apex angle formed between wedge 1 51 and wedge 2 52 changes from pointing towards the drive motor 15 to pointing towards the gantry frame 12 (see details). Figure 5 and Figure 6 This changes the direction of the vacuum cleaner 54 fixedly connected to the second wedge 52. Then the round rod 47 drives the first wedge 51 and the second wedge 52 to continue moving, thereby contacting the squeezing rod 56 inside the positioning frame 41 located at the end away from the drive motor 15, and repeating the cycle.

[0099] It should be noted that during the above process, the apex formed between wedge 1 51 and wedge 2 52 will continuously contact the squeezing rods 56 set at both ends of the positioning frame 41 as the reciprocating motion continues, thereby changing the direction of the vacuum cleaner 54 suction port.

[0100] By setting up wedge 1 51, wedge 2 52, and extrusion rod 56, the deflection direction of the vacuum cleaner 54's suction port is changed, and the deflection direction of the suction port is always opposite to the forward direction of the grinding disc 48. When the deflection direction of the suction port is opposite to the forward direction of the grinding disc 48, it can better guide the airflow. The dust generated during the grinding process will fly forward as the grinding disc 48 rotates, and the reverse-deflected suction port can directly target the dust diffusion path. This setting is like setting up an "interception channel" for the dust, making it easier for the dust to enter the suction port. When grinding the cut surface of the exterior wall insulation board, the dust will fly out along the tangent direction of the grinding disc 48. The reverse-deflected suction port can suck up this dust in time, reducing the dust's residence time and diffusion range in the air.

[0101] Finally, as the conveyor belt 17 continues to transport the material, the cut exterior wall insulation board falls off the main frame 11 of the cutting device. The workers collect the cut exterior wall insulation board, and the cutting of the exterior wall insulation board is completed.
