Description

Technical Field

[0001] This invention relates to the field of grooving machine technology, specifically a grooving machine for exterior wall decorative panels. Background Technology

[0002] Exterior wall decorative panels are building materials used for the decoration and protection of building exteriors. They are characterized by their aesthetic appeal, thermal insulation and energy efficiency, and ease of construction. Grooving of exterior wall decorative panels refers to the processing procedure of cutting grooves of specified dimensions, shapes, and depths on the edges, surfaces, or specific locations of the panels using a specialized grooving machine. Among these, bending and grooving of exterior wall decorative panels is a pre-treatment process for aluminum composite panels, carbon crystal panels, aluminum cone core 3D panels, and other exterior wall decorative panels that require bending. Grooving is done at specific locations on the panels before bending, which solves the problems of easy breakage and inaccurate angles when bending directly, ensuring the aesthetic effect and structural stability of the exterior wall decoration. In existing cutting and grooving equipment, when the cutting tool rotates at high speed and contacts the decorative panel material and moves along the cutting path, the contact pressure between the cutting tool and the material can easily cause the cutting tool to vibrate and deviate from the cutting path. At the same time, when the vibration amplitude is too large, the saw disc is prone to breakage and flying out. In addition, the cutting contact pressure of the cutting tool on the decorative panel causes the decorative panel to move. When the friction force cannot limit its movement, the decorative panel will deviate. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a grooving machine for exterior wall decorative panels, comprising: A frame, in which a cutting platform is fixedly installed, and on both sides of the frame a pressure plate mechanism is fixedly installed, the pressure plate mechanism being located on both sides of the top of the cutting platform; A grooving mechanism is installed inside the frame and is located at the center of the top of the cutting platform; The grooving mechanism includes a shaft groove plate, which is fixedly installed on the top of both sides of the frame, and a lead screw is rotatably installed between the shaft groove plates. The lead screw is threaded with a screw hole plate on its outer side. An inner clamping plate is fixedly installed at the bottom of the screw hole plate. Side circular plates are fixedly installed on both sides of the inner clamping plate. A second motor is fixedly installed on the outer side of each side circular plate. A sawing disc is fixedly installed at the output end of the second motor. A pressure plate cover is fixedly installed on the side of the sawing disc closest to the second motor. A collar is rotatably installed on the inner wall of the pressure plate cover. When the sawing disc and the pressure plate cover on the side closest to the second motor cooperate, the second motor drives the sawing disc to rotate at high speed to cut the exterior wall decorative panel material. The fixed connection between the pressure plate cover and the sawing disc drives the pressure plate cover to rotate synchronously. At the same time, during the rotation, the collar rotatably connects the output end and the pressure plate cover to restrict the sawing disc and prevent it from shaking due to the interaction force during high-speed rotation and cutting, thus preventing it from deviating from the cutting path. If the shaking amplitude is too large, the sawing disc is prone to breakage and flying out. The inner wall of the collar is rotatably connected to the outer side of the output shaft of the second motor. The included angle between the axes of the sawing discs is perpendicular.

[0004] Preferably, a reducer is fixedly installed on the outer side of the shaft groove plate. The output end of the reducer is fixedly connected to one end of the lead screw through a coupling. A first motor is fixedly installed on the outer side of the reducer. The output end of the first motor is fixedly connected to the output end of the reducer through a coupling. A saw disc cover is fixedly installed on the outer side of the second motor. The saw disc is located inside the saw disc cover. A top slide rail is fixedly installed on the top of the inner wall of the frame. The top slide rail is symmetrically installed along the center position of the axis of the frame. Both sides of the bottom of the top slide rail are provided with convex strips, and the top of the convex strips is uniformly provided with arc-shaped protrusions. The arc-shaped protrusions on the top of the top slide rail convex strips contact the sliding groove of the side slide block. During the sliding process, the side slide block contacts the arc-shaped protrusions, reducing the frictional resistance during sliding. At the same time, a dust retention gap is formed between the arc-shaped protrusions, allowing dust and foreign objects to enter between the arc-shaped protrusions and preventing obstruction when the side slide block slides. A side slide block is slidably installed on the bottom of the top slide rail. The top of the side slide block is provided with a sliding groove, and the sliding groove of the side slide block contacts the arc-shaped protrusion of the top slide rail.

[0005] Preferably, the cutting platform includes a fixed frame, which is fixedly installed at the center of the inner wall of the frame. A connecting plate is fixedly installed on the top of the fixed frame. The connecting plate is symmetrically installed along the center of the axis of the fixed frame. A bottom support plate is fixedly installed on the top of the connecting plate. The top of the bottom support plate has symmetrically formed grooves, and rubber strips are fixedly installed at each groove. The top of the rubber strips is uniformly provided with inclined protrusions. Through the cooperation of the inclined protrusions on the top of the rubber strips with the bottom support plate, when the pressure plate mechanism does not apply pressure to the exterior wall decorative panel, the inclined protrusions contact the bottom of the decorative panel, creating a gap between the bottom of the decorative panel and the bottom support plate, reducing the contact area, reducing friction, and facilitating the position adjustment of the decorative panel. An inclined slot is formed at the center of the top of the bottom support plate. The two sides of the inclined slot slope inward from top to bottom, and the inclined slot is located directly below the lead screw.

[0006] Preferably, the pressure plate mechanism includes a fixed clamping plate, which is fixedly installed on both sides of the frame. The bottom of the fixed clamping plate is symmetrically provided with protrusions. A cylinder is fixedly installed at each of the protrusions of the fixed clamping plate. A connecting buckle is fixedly installed at the output end of each cylinder. A fixed buckle is rotatably installed on the inner wall of each connecting buckle. A sliding plate is fixedly installed at the bottom of each fixed buckle. The sliding plate is slidably connected to the sliding groove of the sliding groove plate via the protrusion of the sliding plate. During the cutting process, the cutting contact pressure of the tool on the decorative panel causes the decorative panel to move. When friction cannot restrict its movement, the friction between the rubber pad and the decorative panel is used to make the sliding groove plate move with the decorative panel. Simultaneously, the protrusion of the sliding plate is axially aligned with the lead screw, protecting the tool and preventing the cutting path of the decorative panel from deviating. A protrusion is provided at the center of the bottom of the sliding plate.

[0007] Preferably, a sliding groove plate is installed at the bottom of the sliding strip plate, and a sliding groove is formed at the top of the sliding groove plate. The sliding groove plate slides and adapts to the convex strip of the sliding strip plate through the sliding groove. A rubber pad plate is fixedly installed at the bottom of the sliding groove plate. The rubber pad plate cooperates with the rotating connection between the connecting buckle and the fixing buckle. When contacting the top of the decorative panel, the bottom of the rubber pad plate contacts the top of the decorative panel. At the same time, according to the flatness of the top of the decorative panel, the connecting buckle and the fixing buckle rotate to ensure the fit between the rubber pad plate and the decorative panel. This prevents the contact area from being too small, which would reduce the fixing effect of the decorative panel. A bottom groove is formed at the bottom of the rubber pad plate, and the bottom groove is evenly installed along the axial direction at the bottom of the rubber pad plate.

[0008] This invention provides a grooving machine for exterior wall decorative panels. It has the following beneficial effects: (i) The grooving machine for exterior wall decorative panels uses a sawing disc in conjunction with a pressure plate cover near the second motor. When the second motor drives the sawing disc to rotate at high speed to cut the exterior wall decorative panel material, the pressure plate cover rotates synchronously due to the fixed connection between the pressure plate cover and the sawing disc. At the same time, during the rotation, a collar is used to rotate between the output end and the pressure plate cover to restrict the sawing disc and prevent it from shaking due to the interaction force during high-speed rotation and cutting, thus preventing it from deviating from the cutting path. In addition, if the shaking amplitude is too large, the sawing disc is prone to breakage and flying out.

[0009] (ii) The grooving machine for exterior wall decorative panels uses the arc-shaped protrusion at the top of the top slide rail to contact the slide groove of the side slide block. During the sliding process, the arc-shaped protrusion contacts the side slide block, reducing the frictional resistance during sliding. At the same time, a dust retention gap is formed between the arc-shaped protrusions, allowing dust and foreign objects to enter between the arc-shaped protrusions, preventing obstruction when the side slide block slides.

[0010] (III) The grooving machine for exterior wall decorative panels uses the inclined protrusion on the top of the rubber strip to cooperate with the bottom support plate. When the pressure plate mechanism does not apply pressure to the exterior wall decorative panel, the inclined protrusion contacts the bottom of the decorative panel, so that there is a gap between the bottom of the decorative panel and the bottom support plate, reducing the contact area, reducing friction, and facilitating the position adjustment of the decorative panel.

[0011] (iv) The grooving machine for exterior wall decorative panels is slidably connected by the convex strip of the slide plate and the slide groove of the slide plate. During the cutting process, the cutting contact pressure of the cutter on the decorative panel causes the decorative panel to move. When the friction force cannot restrict its movement, the friction force between the rubber pad and the decorative panel is used to make the slide plate move with the decorative panel. At the same time, the convex strip of the slide plate and the lead screw are axially aligned, which protects the cutter and prevents the cutting path of the decorative panel from deviating.

[0012] (v) The grooving machine for exterior wall decorative panels makes contact between the bottom of the rubber pad and the top of the decorative panel. At the same time, according to the flatness of the top of the decorative panel, the connecting buckle and the fixing buckle rotate to ensure the fit between the rubber pad and the decorative panel and prevent the contact area from being too small, which would reduce the fixing effect of the decorative panel.

[0015] 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.

[0016] For the first embodiment, please refer to... Figures 1 to 2 and Figures 8 to 10 The present invention provides a technical solution: A grooving machine for exterior wall decorative panels, comprising: The frame 1 has a cutting platform 4 fixedly installed inside it, and pressure plate mechanisms 3 are fixedly installed on both sides of the frame 1. The pressure plate mechanisms 3 are located on both sides of the top of the cutting platform 4. The grooving mechanism 2 is installed inside the frame 1 and is located at the center of the top of the cutting platform 4; The grooving mechanism 2 includes a shaft groove plate 201, which is fixedly installed on the top of both sides of the frame 1, and a lead screw 205 is rotatably installed between the shaft groove plates 201. A screw hole plate 206 is threadedly connected to the outer side of the lead screw 205. An inner clamping plate 208 is fixedly installed at the bottom of the screw hole plate 206. Side circular plates 210 are fixedly installed on both sides of the inner clamping plate 208. A second motor 209 is fixedly installed on the outer side of the side circular plates 210. A sawing disc 212 is fixedly installed at the output end of the second motor 209. During the movement, the second motor 209 drives the sawing disc 212 to rotate at high speed inside the saw disc cover 211, so that the sawing disc 212 cuts the exterior wall decorative panel. Taking advantage of the perpendicular angle between the axes of the sawing discs 212, a bending groove is cut at the slotted position of the exterior wall decorative panel. A pressure plate cover 214 is fixedly installed on the side of the sawing disc 212 near the second motor 209. A collar 213 is rotatably installed on the inner wall of the pressure plate cover 214. The inner wall of the collar 213 is rotatably connected to the outer side of the output shaft of the second motor 209. The angle between the axes of the sawing discs 212 is perpendicular.

[0017] A reducer 202 is fixedly installed on the outer side of the shaft groove plate 201. The output end of the reducer 202 is fixedly connected to one end of the lead screw 205 via a coupling. A first motor 203 is fixedly installed on the outer side of the reducer 202. The output end of the first motor 203 is fixedly connected to the output end of the reducer 202 via a coupling. A saw disc cover 211 is fixedly installed on the outer side of the second motor 209. The sawing disc 212 is located inside the saw disc cover 211. Before cutting, the position of the groove of the exterior wall decorative panel is adjusted to correspond with the position of the sawing disc 212. Then, the first motor 203 and the second motor 209 are started, causing the output end of the first motor 203 to rotate. After the speed is reduced by the reducer 202, the lead screw 205 is driven to rotate. The threaded connection between the lead screw 205 and the screw hole plate 206 allows the screw hole plate 206 to move along the axial direction of the side circular plate 210 via the inner clamping plate 208, under the sliding connection restriction between the side slider 207 and the top slide rail 204. This causes the sawing disc 212 to move along the grooving cutting path of the exterior wall decorative panel. The top slide rail 204 is fixedly installed on the top of the inner wall of the frame 1. The top slide rail 204 is symmetrically installed along the center position of the axis of the frame 1. The bottom of both sides of the top slide rail 204 is provided with convex strips, and the top of the convex strips is uniformly provided with arc-shaped protrusions. The bottom of the top slide rail 204 is slidably installed with a side slider 207. The top of the side slider 207 is provided with a sliding groove, and the sliding groove of the side slider 207 contacts the arc-shaped protrusion of the top slide rail 204.

[0018] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 3 to 4As shown, the cutting platform 4 includes a fixed frame 44, which is fixedly installed at the center of the inner wall of the frame 1. A connecting plate 45 is fixedly installed on the top of the fixed frame 44. The connecting plate 45 is symmetrically installed along the center of the axis of the fixed frame 44 and cooperates with the bottom support plate 41 through a rubber strip 42. After the exterior wall decorative panel is placed, it contacts the bottom of the exterior wall decorative panel and supports it. At the same time, when the pressure plate mechanism 3 does not apply pressure to the panel, the protrusion on the top of the rubber strip 42 prevents the bottom of the exterior wall decorative panel from contacting the top of the bottom support plate 41, reducing the contact area. A bottom support plate 45 is fixedly installed on the top of the connecting plate 45. The top of the support plate 41 and the bottom support plate 41 are symmetrically provided with grooves, and rubber strips 42 are fixedly installed in the grooves of the bottom support plate 41. The top of the rubber strips 42 are evenly provided with inclined protrusions. When the position adjustment of the exterior wall decorative panel is completed, the pressure plate mechanism 3 applies pressure to both sides of the top of the decorative panel, so that the decorative panel transmits the pressure to the rubber strips 42, causing the rubber strips 42 to deform and compress under pressure, so that the bottom of the decorative panel fits the top of the bottom support plate 41. The center of the top of the bottom support plate 41 is provided with an inclined slot 43. The two sides of the inclined slot 43 are inclined inward from top to bottom, and the inclined slot 43 is located directly below the screw rod 205.

[0019] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 5 to 7 As shown, the pressure plate mechanism 3 includes a fixed clamping plate 31, which is fixedly installed on both sides of the frame 1. The bottom of the fixed clamping plate 31 is symmetrically provided with protrusions. A cylinder 32 is fixedly installed at each of the protrusions of the fixed clamping plate 31. After the decorative panel is adjusted, the output end of the cylinder 32 drives the connecting buckle 33 to move down and connects to the slide plate 35 through the fixed buckle 34, thus driving the slide plate 35. When it contacts the decorative panel, the bottom of the rubber pad 37 contacts both sides of the top of the decorative panel. Then, under the continuous pressure of the cylinder 32, the rubber pad 37 is deformed and compressed. The output end of the cylinder 32 is fixedly installed with the connecting buckle 33. The inner wall of the connecting buckle 33 is rotatably installed with the fixed buckle 34. The bottom of the fixed buckle 34 is fixedly installed with the slide plate 35. A protrusion is provided at the center of the bottom of the slide plate 35.

[0020] A sliding groove plate 36 is installed at the bottom of the sliding strip plate 35. A sliding groove is opened at the top of the sliding groove plate 36, and the sliding groove plate 36 slides and adapts to the protrusion of the sliding strip plate 35 through the sliding groove. A rubber pad plate 37 is fixedly installed at the bottom of the sliding groove plate 36. During the compression process, the air inside the bottom groove 38 of the rubber pad plate 37 is gradually squeezed out through the bottom groove 38. It cooperates with the cutting platform 4 to complete the fixation of the decorative panel. The bottom groove 38 of the rubber pad plate 37 is evenly installed along the axial direction at the bottom of the rubber pad plate 37.

[0021] In use, the metal exterior wall decorative panel to be cut with bending grooves is placed into the equipment. The cutting platform 4 supports the bottom of the panel. Then, the position of the metal exterior wall decorative panel is adjusted so that the groove position of the metal exterior wall decorative panel corresponds to the cutter of the grooving mechanism 2. After the position adjustment is completed, the pressure plate mechanism 3 is activated so that the pressure plate mechanism 3 applies pressure to both sides of the top of the exterior wall decorative panel. In cooperation with the cutting platform 4, the exterior wall decorative panel is clamped and fixed. Then, the grooving mechanism 2 is activated so that the cutter moves along the grooving path to perform grooving processing.

[0022] In the cutting platform 4, the rubber strip 42 cooperates with the bottom support plate 41. After the exterior wall decorative panel is placed, it contacts the bottom of the exterior wall decorative panel and supports it. At the same time, when the pressure plate mechanism 3 does not apply pressure to the panel, the protrusion on the top of the rubber strip 42 prevents the bottom of the exterior wall decorative panel from contacting the top of the bottom support plate 41, reducing the contact area. When the exterior wall decorative panel is adjusted, the pressure plate mechanism 3 applies pressure to both sides of the top of the decorative panel, causing the decorative panel to transfer pressure to the rubber strip 42. The rubber strip 42 deforms and compresses under pressure, so that the bottom of the decorative panel fits against the top of the bottom support plate 41.

[0023] In the pressure plate mechanism 3, after the decorative panel is positioned, the output end of the cylinder 32 drives the connecting buckle 33 to move down, and connects the slide plate 35 through the fixing buckle 34, driving the slide plate 35. When it contacts the decorative panel, the bottom of the rubber pad 37 contacts both sides of the top of the decorative panel. Then, under the continuous pressure of the cylinder 32, the rubber pad 37 is deformed and compressed. At the same time, during the compression process, the air inside the bottom groove 38 of the rubber pad 37 is gradually squeezed out, cooperating with the cutting platform 4 to complete the fixing of the decorative panel.

[0024] In the grooving mechanism 2, before cutting, the grooving position of the exterior wall decorative panel is adjusted to correspond with the position of the sawing disc 212. Then, the first motor 203 and the second motor 209 are started, causing the output end of the first motor 203 to rotate. After the speed is reduced by the reducer 202, the lead screw 205 is driven to rotate. By utilizing the threaded connection between the lead screw 205 and the screw hole plate 206, the screw hole plate 206, under the sliding connection restriction between the side slider 207 and the top slide rail 204, drives the side circular plate 210 to move along the axial direction of the lead screw 205 through the inner clamping plate 208. This causes the sawing disc 212 to move along the grooving cutting path of the exterior wall decorative panel. At the same time, during the movement, the second motor 209 drives the sawing disc 212 to rotate at high speed inside the saw disc cover 211, so that the sawing disc 212 cuts the exterior wall decorative panel after it is behind it. Utilizing the perpendicularity of the included angle between the axes of the sawing discs 212, a bending groove is cut at the grooving position of the exterior wall decorative panel.
