Description

Technical Field

[0001] The present invention relates to the field of gypsum board processing, and in particular to a cutting device and a cutting method for gypsum board molding processing. Background Art

[0002] Gypsum board is a building material with light weight, high strength, thin thickness, good sound insulation, heat insulation and fire resistance, and is now widely used in the construction industry.

[0003] The gypsum board processing technology includes a cutting process, which is used to cut the four sides of the gypsum board to obtain a product that meets the size requirements. Since all four sides of the gypsum board need to be cut, generally two sides of the gypsum board are cut first, then the gypsum board is rotated ninety degrees, and then the remaining two sides of the gypsum board are cut. Among them, the accuracy of the gypsum board rotation of ninety degrees is one of the important factors affecting the cutting quality. If the rotation angle is too small or too large, it will affect the final cutting result.

[0004] Based on the search for the rotation reversal of plate-like objects, a Chinese invention patent was found, and its authorization announcement number is CN108311932B, which discloses a steel plate cutting device with a steering function. When driving the steel plate to rotate and reverse, after the steel plate is pulled to a preset position, the turntable is driven to rise by the turntable lifter, and the steel plate is lifted off the steering conveyor belt. Then, the turntable is driven to rotate by the steering driver, so that the turntable drives the steel plate to turn. After the steering is completed, the turntable lifter drives the turntable to descend, and the steel plate is pulled to the cutting blade direction by the steering conveyor belt. Although this steering structure can realize the function of rotation reversal However, there are some shortcomings: on the one hand, since two power sources, the turntable lifter and the steering driver, are required to achieve the purpose of rotational reversal, and since the rotational reversing action includes three sub-actions: turntable rising, rotation, and lowering, the connection between the sub-actions is not smooth enough, and there is some delay. When applied to large-scale production lines, it will inevitably affect the production efficiency and needs to be improved; on the other hand, in order to ensure the cutting quality, the accuracy of the rotational reversal needs to be guaranteed. Since steel plates or gypsum boards have a rotational inertia when rotating, the rotation speed of the turntable should be relatively slow, which will affect the production efficiency.

[0005] Based on the above problems, the present invention proposes a cutting device and a cutting method for gypsum board forming processing. Summary of the Invention

[0006] In order to solve the problems mentioned in the above background, the present invention provides a cutting device and a cutting method for gypsum board molding processing.

[0007] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows.

[0008] A cutting device for gypsum board forming processing includes a frame, a synchronous belt, a cutting member, and a rotary reversing assembly provided on the frame, the synchronous belt being arranged in a horizontal conveying direction, two synchronous belts being provided along the width direction of the synchronous belt, two cutting members being provided along the conveying direction of the synchronous belt, and the rotary reversing assembly being located between the two cutting members; The rotary reversing assembly includes a connecting bracket, on which a vertically arranged rotating shaft is mounted. The upper end of the rotating shaft extends out of the connecting bracket and is provided with a connecting seat. The connecting seat is provided with a support disk. Initially, the height of the upper end surface of the support disk is lower than the height of the upper surface of the synchronous belt. A friction plate is provided on the outside of the rotating shaft via a spline. When relative displacement occurs between the friction plate and the rotating shaft, the spline maintains a dynamic connection between the two. A fixing ring is provided at the lower end of the rotating shaft. A first spring is provided between the fixing ring and the friction plate. The upper surface of the friction plate is in contact with the connecting bracket. The connecting bracket is provided with a driving component for driving the rotating shaft to rotate and move.

[0009] Furthermore, the connecting bracket is provided with a side groove along one side of the width direction of the synchronous belt, and a horizontal rod is provided in the side groove. The extension direction of the horizontal rod is parallel to the conveying direction of the synchronous belt. An inclined rod is hingedly provided at one end of the horizontal rod toward the feed end of the synchronous belt, and the bottom of the inclined rod is supported by the lower groove wall of the side groove.

[0010] Furthermore, the driving component includes a slide seat slidably arranged on the connecting bracket along the conveying direction of the synchronous belt and a second telescopic rod for driving the slide seat to move; A connecting rod is provided on the slide seat for sliding in the vertical direction, a second spring is provided above the connecting rod, and a convex pin is provided on the side of the connecting rod. Initially, the convex pin is supported by the lower groove wall of the side groove, and the convex pin is located on the side of the tilting rod facing the feeding end of the synchronous belt.

[0011] Furthermore, a lifting rod is provided on the rotating shaft through a bearing, and the lifting rod is supported by a connecting rod.

[0012] Furthermore, a gear is provided on the rotating shaft via a spline. When relative displacement occurs between the gear and the rotating shaft, a dynamic connection is maintained between the two, and the connecting bracket restricts the gear to only rotate. A rack is provided on the connecting rod, and the extension direction of the rack is parallel to the conveying direction of the synchronous belt. When the convex pin is supported by the horizontal rod and moves away from the feed end of the synchronous belt, the rack can engage with the gear. In the process from the engagement of the rack and the gear to the disengagement of the rack and the gear, the gear rotates ninety degrees.

[0013] Furthermore, the cutting component includes a pressing component and a cutting component, and the cutting component is located in front of the pressing component along the conveying direction of the synchronous belt.

[0014] Furthermore, a support rod for supporting the synchronous belt is provided on the frame.

[0015] Furthermore, the cutting assembly includes a motor, both ends of the motor output shaft extend out of the motor housing and are each poweredly connected to a cutting tool, and the two cutting tools are located on opposite sides of the two synchronous belts.

[0016] Furthermore, the pressing assembly includes a gantry bracket slidably arranged on the frame along the conveying direction of the synchronous belt, a pressing bracket slidably arranged on the gantry bracket along the vertical direction, the pressing bracket is located above the synchronous belt, and a first telescopic rod is provided on the gantry bracket for driving the pressing bracket to move; A limit protrusion and a fixed pulley are provided on the frame. The limit protrusion is located behind the gantry bracket along the conveying direction of the synchronous belt. Initially, the gantry bracket is in contact with the limit protrusion. A connecting rope is provided on the gantry bracket, and a counterweight is provided at the end of the connecting rope after passing through a fixed pulley.

[0017] A cutting method for cutting equipment used in gypsum board forming processing: Step 1: Place the gypsum board on the feeding end of the synchronous belt and use the synchronous belt to pull the gypsum board to move; Step 2: Cut both sides of the gypsum board using the first cutting member; Step 3: After cutting, the gypsum board is pulled to the top of the support plate by the synchronous belt; Step 4: The second telescopic rod is activated, and the traction slide moves away from the feeding end of the synchronous belt. During this movement: The convex pin moves upward along the tilt rod and is then supported by the horizontal rod. During this stage, the convex pin moves upward with the connecting rod, which in turn moves upward with the lifting rod, rotating shaft, connecting seat, and support plate, lifting the gypsum board upward through the support plate. At the same time, the first spring is compressed, the friction plate contacts the connecting bracket, and the second spring is compressed. The protruding pin is supported by the horizontal rod and continues to move. During this stage, the rack and gear cooperate to drive the rotating shaft to rotate 90 degrees. The rotating shaft rotates 90 degrees with the connecting seat, support plate and gypsum board. The protruding pin is separated from the horizontal rod. Under the elastic force of the second spring, the connecting rod falls downward until it is supported by the lower wall of the side groove. At the same time, under the elastic force of the first spring, the rotating shaft moves downward with the connecting seat, the supporting plate and the gypsum board, so that the gypsum board falls back onto the synchronous belt. Step 5: Continue to pull the gypsum board to move through the synchronous belt, and cut the remaining two sides of the gypsum board through the second cutting member.

[0018] Compared with the prior art, the present invention has the following beneficial effects: This solution can realize the automatic cutting of gypsum board. Specifically, this solution uses a synchronous belt to pull the gypsum board to move, and the first cutting component is used to cut both sides of the gypsum board. Then, the rotating reversing component is used to pull the gypsum board to rotate 90 degrees, and finally, the second cutting component is used to cut the remaining two sides of the gypsum board. In this process: 1. The rotary reversing assembly uses a single power source to achieve the following sub-actions: lifting the gypsum board off the synchronous belt - pulling the gypsum board to rotate 90 degrees - pulling the gypsum board back onto the synchronous belt. The sub-actions are smoothly connected and more efficient. 2. When the gypsum board is lifted off the synchronous belt, the first spring is compressed, and the friction between the friction plate and the connecting bracket increases. The friction plate maintains a dynamic connection with the rotating shaft through the spline, so the rotational damping of the rotating shaft increases. The advantage is that in the subsequent rotation process, after the gear and rack are disengaged, the rotating shaft stops rotating immediately, solving the rotation accuracy problem caused by the rotation inertia of the rotating shaft. Therefore, the working accuracy of the rotary reversing component is higher, which indirectly improves the cutting quality. In addition, the rotation direction of the rotating shaft can also become faster, thereby further improving the cutting efficiency. 3. The resetting of the holding component in the cutting member is achieved by the counterweight block. The advantage is that, in the process of holding the gypsum board for cutting, the resetting force on the gantry bracket remains consistent. If the existing spring technology that is easy to think of is used, then as the cutting action proceeds, the compression of the spring gradually increases, and the resetting force on the gantry bracket gradually increases, which is prone to pressure transition, resulting in a change in the moving speed of the gypsum board and an inability to maintain a constant speed. As we all know, when cutting an object, the relative moving speed between the object and the knife must be kept constant, otherwise it is easy to cause burrs on the cutting surface, affecting the cutting quality.

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0022] Reference Figures 1-9 A cutting device for gypsum board forming processing includes a frame 100, on which a synchronous belt 101, a pressing component 200, a cutting component and a rotation reversing component 300 are provided, wherein: The conveying direction of the synchronous belt 101 is arranged horizontally. Two synchronous belts 101 are provided along their width direction. The gypsum board to be cut is placed on the synchronous belt 101 manually or by existing robotic arm technology, and the gypsum board is pulled by the synchronous belt 101 to move; Two pressing assemblies 200 are provided along the conveying direction of the synchronous belt 101, which are used to press the gypsum board from above and cooperate with the cutting assembly to cut the gypsum board; The cutting assembly is located in front of the pressing assembly 200 along the conveying direction of the synchronous belt 101, and two cutting assemblies are correspondingly provided; The rotation reversing assembly 300 is located between the two cutting assemblies and also between the two pressing assemblies 200, and is used to pull the gypsum board to rotate ninety degrees to achieve rotation reversal.

[0023] In this way, they cooperate with each other to achieve the cutting of the gypsum board.

[0024] Preferred embodiment, see Figure 1The frame 100 is provided with a support rod for supporting the synchronous belt 101. Its significance is that when the gypsum board is pressed, the synchronous belt 101 is relatively soft and easily concave downward. By supporting the synchronous belt 101 through the support rod, it can be ensured that the gypsum board can be pressed smoothly.

[0025] Reference Figure 3 The cutting assembly includes a motor 104 , both ends of the output shaft of the motor 104 extend out of the motor housing and are each powered by a cutting tool 103 , and the two cutting tools 103 are located on opposite sides of the two synchronous belts 101 .

[0026] Reference Figure 2-Figure 4 The pressing assembly 200 includes a gantry bracket 201 that is slidably arranged on the frame 100 along the conveying direction of the synchronous belt 101, and a pressing bracket 202 is slidably arranged on the gantry bracket 201 along the vertical direction. The pressing bracket 202 is located above the synchronous belt 101, and a first telescopic rod 203 for driving the pressing bracket 202 to move is provided on the gantry bracket 201. The first telescopic rod 203 and the second telescopic rod 302 mentioned later can be realized by using existing technologies, such as electric telescopic rods, pneumatic telescopic rods, etc., which will not be described in detail.

[0027] After the gypsum board is pulled to the bottom of the pressing bracket 202 by the synchronous belt 101, the first telescopic rod 203 drives the pressing bracket 202 to move downward, and cooperates with the synchronous belt 101 to press the gypsum board. After that, the synchronous belt 101 continues to pull the gypsum board to move, and the pressing bracket 202 presses the gypsum board while moving together. During the movement, the gypsum board passes through the cutting assembly and is cut off on both sides by the two cutting tools 103. After the cutting action is completed, the first telescopic rod 203 drives the pressing bracket 202 to move upward and release the pressure. At the same time, the reset member drives the gantry bracket 201 to reset.

[0028] Furthermore, the reset member includes a connecting rope 205, a limiting protrusion 102 and a fixed pulley 204 provided on the frame 100. The limiting protrusion 102 is located behind the gantry bracket 201 along the conveying direction of the synchronous belt 101. Initially, the gantry bracket 201 is in contact with the limiting protrusion 102.

[0029] One end of the connecting rope 205 is connected to the gantry bracket 201, and the other end is provided with a counterweight block 206 after passing around the fixed pulley 204; the advantage of this reset component is that, in the process of pressing the gypsum board for cutting, the reset force received by the gantry bracket 201 remains consistent. If the existing spring technology that is easy to think of is adopted, then as the cutting action proceeds, the compression of the spring gradually increases, and the reset force received by the gantry bracket 201 gradually increases, and a pressing transition is likely to occur, resulting in a change in the moving speed of the gypsum board and an inability to maintain a constant speed. As we all know, when cutting an object, the relative moving speed between the object and the knife must be kept constant, otherwise it is easy to cause burrs on the cutting surface, affecting the cutting quality. Therefore, this solution has improved the reset component and does not adopt the existing spring technology.

[0030] Reference Figure 5-Figure 9 The rotation reversing assembly 300 includes a connecting bracket 301 connected to the frame 100, and a vertically arranged rotating shaft 305 is installed on the connecting bracket 301. The rotating shaft 305 can rotate around its own axis and move along its own axis.

[0031] The upper end of the rotating shaft 305 extends out of the connecting bracket 301 and is provided with a connecting seat 304 , on which a supporting disk 303 is provided. Initially, the height of the upper end surface of the supporting disk 303 is lower than the height of the upper surface of the synchronous belt 101 .

[0032] A friction plate 307 is provided on the outside of the rotating shaft 305 through a spline. When relative displacement occurs between the friction plate 307 and the rotating shaft 305, the two maintain a dynamic connection through the spline. A fixing ring is provided at the lower end of the rotating shaft 305, and a first spring 308 is provided on the outside of the rotating shaft 305 between the fixing ring and the friction plate 307. Initially, the upper surface of the friction plate 307 is in contact with the connecting bracket 301.

[0033] The connecting bracket 301 is provided with a driving component, which is used to drive the rotating shaft 305 to rotate and move.

[0034] Furthermore, the connecting bracket 301 is provided with a side groove 3011 on one side along the width direction of the synchronous belt 101, and a horizontal rod 3012 is provided in the side groove 3011. The extension direction of the horizontal rod 3012 is parallel to the conveying direction of the synchronous belt 101. There is a gap between the end of the horizontal rod 3012 facing the discharge end of the synchronous belt 101 and the groove wall of the side groove 3011. The end of the horizontal rod 3012 facing the feed end of the synchronous belt 101 is hingedly provided with an inclined rod 3013, and the bottom of the inclined rod 3013 is supported by the lower groove wall of the side groove 3011.

[0035] The driving component includes a slide 309 slidably arranged on the connecting bracket 301 along the conveying direction of the synchronous belt 101 and a second telescopic rod 302 for driving the slide 309 to move.

[0036] A connecting rod 310 is provided on the slide 309 for sliding in the vertical direction, a second spring 311 is provided above the connecting rod 310, and a protruding pin 312 is provided on the side of the connecting rod 310. Initially, the protruding pin 312 is supported by the lower groove wall of the side groove 3011, and the protruding pin 312 is located on the side of the tilting rod 3013 facing the feed end of the synchronous belt 101.

[0037] During the movement of the second telescopic rod 302 pulling the slide 309 away from the feed end of the synchronous belt 101, the convex pin 312 will move up along the inclined rod 3013, and then be supported by the horizontal rod 3012, and then break away from the horizontal rod 3012, fall and be supported by the lower groove wall of the side groove 3011 again. Then, during the movement of the second telescopic rod 302 pulling the slide 309 close to the feed end of the synchronous belt 101, the convex pin 312 will push the inclined rod 3013 to swing upward, and the convex pin 312 will smoothly cross the inclined rod 3013 and return to its initial position. The movement of the convex pin 312 will move with the connecting rod 310.

[0038] A lifting rod 314 is provided on the rotating shaft 305 through a bearing. The lower surface of the lifting rod 314 contacts the upper surface of the connecting rod 310, that is, the lifting rod 314 is supported by the connecting rod 310. Therefore, the movement of the connecting rod 310 in the vertical direction will move with the lifting rod 314, and the lifting rod 314 will move with the rotating shaft 305.

[0039] A gear 306 is provided on the rotating shaft 305 via a spline. When relative displacement occurs between the gear 306 and the rotating shaft 305, a dynamic connection is maintained between the two. The connecting bracket 301 restricts the gear 306 to only rotate and not move.

[0040] A rack 313 is provided on the connecting rod 310, and the extension direction of the rack 313 is parallel to the conveying direction of the synchronous belt 101. When the protruding pin 312 is supported by the horizontal rod 3012 and the protruding pin 312 moves away from the feed end of the synchronous belt 101, the rack 313 can engage with the gear 306. In the process from the engagement of the rack 313 and the gear 306 to the disengagement of the rack 313 and the gear 306, the gear 306 rotates ninety degrees, and the gear 306 rotates ninety degrees with the rotating shaft 305.

[0041] A cutting method for cutting equipment used in gypsum board molding processing: Step 1: Place the gypsum board on the feeding end of the synchronous belt 101, and use the synchronous belt 101 to pull the gypsum board to move; Step 2: When the gypsum board is located below the first pressing assembly 200, the gypsum board is pressed by the first pressing assembly 200; Step 3: Continue to pull the gypsum board to move by the synchronous belt 101. During the movement, the first cutting component is used to cut both sides of the gypsum board. Step 4: After the cutting is completed, the first pressing assembly 200 releases the pressing and resets, and the gypsum board is pulled to the top of the support plate 303 via the synchronous belt 101; Step 5: The second telescopic rod 302 is activated, and the traction slide 309 moves away from the feeding end of the synchronous belt 101. During this movement: The protruding pin 312 moves upward along the tilting rod 3013 and is then supported by the horizontal rod 3012. During this stage, the protruding pin 312 moves upward with the connecting rod 310, which in turn moves upward with the lifting rod 314. The lifting rod 314 moves upward with the rotating shaft 305, the connecting seat 304, and the supporting plate 303, thereby lifting the gypsum board upward via the supporting plate 303. At the same time, the first spring 308 is compressed, increasing the friction between the friction plate 307 and the connecting bracket 301. At the same time, the second spring 311 is compressed. The protruding pin 312 is supported by the horizontal rod 3012 and continues to move. During this stage, the rack 313 cooperates with the gear 306 to drive the rotating shaft 305 to rotate 90 degrees. The rotating shaft 305 rotates 90 degrees with the connecting seat 304, the supporting plate 303, and the gypsum board. The protruding pin 312 is separated from the horizontal rod 3012. Under the elastic force of the second spring 311, the connecting rod 310 falls downward until it is supported by the lower groove wall of the side groove 3011. At the same time, under the elastic force of the first spring 308, the rotating shaft 305 moves downward with the connecting seat 304, the supporting plate 303, and the gypsum board, so that the gypsum board falls back onto the synchronous belt 101. Step 6: Continue to pull the gypsum board to move through the synchronous belt 101, repeat steps 2 to 4, and use the second pressing assembly 200 to cooperate with the second cutting assembly to cut the remaining two sides of the gypsum board.

The cutting device for gypsum board molding processing according to claim 6, characterized in that: The pressing assembly (200) comprises a gantry support (201) slidably arranged on the frame (100) along the conveying direction of the synchronous belt (101); a pressing support (202) is slidably arranged on the gantry support (201) along the vertical direction; the pressing support (202) is located above the synchronous belt (101); and a first telescopic rod (203) for driving the pressing support (202) to move is arranged on the gantry support (201); A limit protrusion (102) and a fixed pulley (204) are provided on the frame (100), the limit protrusion (102) is located behind the gantry support (201) along the conveying direction of the synchronous belt (101), and initially, the gantry support (201) is in contact with the limit protrusion (102); A connecting rope (205) is arranged on the gantry support (201), and a counterweight (206) is arranged at the end of the connecting rope (205) after it passes around the fixed pulley (204).

9. A cutting method for a gypsum board forming cutting device as claimed in claim 5, characterized in that: The steps include: Step 1: placing the gypsum board on the feeding end of the synchronous belt (101), and pulling the gypsum board to move by the synchronous belt (101); Step 2: Cut both sides of the gypsum board using the first cutting member; Step 3: After the cutting is completed, the gypsum board is pulled to the top of the support plate (303) by the synchronous belt (101); Step 4: The second telescopic rod (302) is activated, and the traction slide (309) moves away from the feeding end of the synchronous belt (101). During this movement: The convex pin (312) moves upward along the tilting rod (3013) and is then supported by the horizontal rod (3012). During this stage, the convex pin (312) moves upward with the connecting rod (310), and the connecting rod (310) moves upward with the lifting rod (314), the rotating shaft (305), the connecting seat (304) and the supporting plate (303), and the gypsum board is lifted upward through the supporting plate (303). At the same time, the first spring (308) is compressed, the friction plate (307) contacts the connecting bracket (301), and the second spring (311) is compressed. The protruding pin (312) is supported by the horizontal rod (3012) and continues to move. In this stage, the rack (313) cooperates with the gear (306) to drive the rotating shaft (305) to rotate ninety degrees. The rotating shaft (305) rotates ninety degrees with the connecting seat (304), the supporting plate (303) and the gypsum board; The protruding pin (312) is separated from the horizontal rod (3012), and under the elastic force of the second spring (311), the connecting rod (310) falls downward until it is supported by the lower groove wall of the side groove (3011). At the same time, under the elastic force of the first spring (308), the rotating shaft (305) moves downward together with the connecting seat (304), the supporting plate (303) and the gypsum board, so that the gypsum board falls back onto the synchronous belt (101); Step 5: The gypsum board is continued to be pulled by the synchronous belt (101) to move, and the remaining two sides of the gypsum board are cut by the second cutting member.
