Description

Technical Field

[0001] This invention relates to composite board cutting, and more particularly to a cutting device and a processing method for composite boards. Background Technology

[0002] With the rapid development of my country's economy, more and more composite boards are being used in production and daily life. When enterprises produce composite boards in large quantities, the raw boards are very large, so they need to be cut to meet the actual size requirements. Patent publication number (CN106826979A) discloses an environmentally friendly composite board cutting device, including a worktable. A set of trays is provided on the upper surface of the worktable, and each tray has multiple rectangular grooves machined on its upper surface. A top plate is provided on one side of the upper surface of the worktable, and an infrared emitter matching the multiple rectangular grooves is provided on one side of the top plate. A controller is provided on one side of the worktable, and a mains power interface is provided below the controller. The controller's power terminal is connected to the mains power interface via a wire. The controller's input terminal is connected to the infrared emitter, a first electric carriage, a second electric carriage, an electric push rod, and a rotary motor via wires. The beneficial effects of this invention are: the device is simple to operate, has low maintenance costs, fast cutting speed, infrared-indicated cutting to prevent deviation, frees up manpower, reduces economic losses, improves work efficiency, and has a novel structure that is practical and convenient. When using the above technology, the cutting part is moved to control the cutting. During cutting, the board is placed on the pallet and anti-slip pads are used to prevent the board from shifting. However, the anti-slip pads are not very effective in preventing the board from shifting. Furthermore, when cutting multiple boards, each board needs to be placed and cut one by one, and then removed and a new board placed after cutting, resulting in low cutting efficiency.

[0010] Furthermore, two support plates are fixedly connected to the lower surface of the workbench, and a chip collection box is fixedly connected to the right side of the support plates on the lower surface of the workbench.

[0011] Furthermore, the upper surface of the workbench is provided with a through-type mounting groove, and multiple rolling rollers are rotatably connected to the inner side of the mounting groove via a rotating shaft.

[0012] Furthermore, the upper surface of the workbench is symmetrically and fixedly connected with fixed frames. Multiple shafts are rotatably connected inside the fixed frames via rotating shafts.

[0013] According to another aspect of the present invention, a cutting method for processing composite boards is provided, comprising the following steps: S1.

S2. Start motor two, drive the double-headed fan-shaped extrusion wheel on the outer wall of shaft two to rotate, intermittently push the plate to move, so that the plate is close to the cutting wheel for cutting; S3. Start motor one to drive the cutting wheel to rotate and cut the board.

[0014] Beneficial effects: Motor 2 drives shaft 2 to rotate, which in turn drives the double-headed fan-shaped extrusion wheel to move and rotate. Through the intermittent transmission of the double-headed fan-shaped extrusion wheel, the sheet material is extruded towards the cutting wheel, achieving the effect of intermittent cutting. When the second motor drives the double-headed fan-shaped extrusion wheel to rotate, it can pull the first shaft to slide back and forth along the inclined groove. This allows the cutting wheel to move closer to the plate when it moves down along the inclined groove and move away from the plate when it moves up. This avoids friction during cutting, thus achieving a cooling effect and extending the service life of the cutting wheel. When the double-headed fan-shaped extrusion wheel rotates, it will squeeze the piston plate four repeatedly along the inside of the box four through the wedge-shaped push block two. Then, gas can be filled into the water storage tank through the one-way air outlet valve, which will drive the piston plate three to descend and squeeze the water storage tank to drain a certain amount of water. The discharged water will be sprayed onto the cutting wheel through the nozzle for cooling effect. The starting motor drives the gear to rotate, and the arc rack can intermittently rotate the shaft column. This allows the movable rod to move the two opposing straightening plates relative to each other to clamp the plate for straightening. At the same time, the plate can be pushed slightly to the right, which in turn can push the plate to move and achieve the effect of moving the cutting edge. Attached Figure Description

[0016] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1 like Figure 1 and Figure 4 As shown, a cutting device for processing composite boards is provided, including a worktable 1. Fixed plates 2 are symmetrically fixedly connected to the right side of the upper surface of the worktable 1. A through-type inclined groove 3 is opened on the opposite side of the two fixed plates 2. A shaft 4 is provided on the inner side of the two inclined grooves 3. A cutting wheel 5 is fixedly connected to the outer wall of the shaft 4. Vertical grooves 21 are symmetrically opened on the rear surface of the fixed plate 2 located behind the upper surface of the worktable 1. A lifting block 22 is slidably connected inside the vertical groove 21. A motor 23 is fixedly connected to the rear surface of the two lifting blocks 22. The front end of the output shaft of the motor 23 is fixedly connected to the rear end of the shaft 4. The workbench 1 is used to place the board. The motor 23 is started to drive the shaft 4 to rotate, so that the cutting wheel 5 can achieve the effect of rotating and cutting. The shaft 4 can slide along the inclined groove 3, driving the cutting wheel 5 away from or closer to the board.

[0018] like Figure 1 As shown, the upper surface of the workbench 1 is fixedly connected to the left side of the two fixed plates 1 2, and the two fixed plates 2 6 are rotatably connected to the shaft 2 7 through a rotating shaft. The outer side wall of the shaft 2 7 is fixedly connected to two bushings 8, and the outer side wall of the bushings 8 is fixedly connected to a double-headed fan-shaped extrusion wheel 9. The rear surface of the water tank 24 is fixedly connected to the motor 2 35, and the front end of the output shaft of the motor 2 35 is fixedly connected to the rear end of the shaft 2 7. Motor 2 35 drives shaft 2 7 to rotate, which in turn drives the double-headed fan-shaped extrusion wheel 9 to move and rotate. Through the intermittent transmission of the double-headed fan-shaped extrusion wheel 9, the plate material is extruded towards the cutting wheel 5, achieving the effect of intermittent cutting.

[0019] like Figure 1 and Figure 2 As shown, a housing 10 is fixedly connected to the front surface of a fixed plate 2 located in front of the upper surface of the worktable 1. The interior of the housing 10 is connected to the interior of an inclined groove 3 located in front of the upper surface of the worktable 1. A lifting frame 11 is slidably connected inside the housing 10. A housing 12 is fixedly connected to the front surface of a fixed plate 6 located in front of the upper surface of the worktable 1. A piston plate 13 is slidably connected inside the housing 12. A connecting rod 14 is fixedly connected between the piston plate 13 and the lifting frame 11. A housing 16 is fixedly connected to the rear surface of a fixed plate 6 located in front of the upper surface of the worktable 1. Piston plate 17 is slidably connected inside the housing 16. A wedge-shaped push block 18 is fixedly connected between piston plate 17 and housing 16. A ventilation pipe 19 is fixedly connected between housing 16 and housing 2. The front end of shaft 4 extends into the interior of lifting frame 11 and is slidably connected to lifting frame 11. Multiple springs 15 are fixedly connected between piston plate 13 and housing 2. Multiple springs 20 are fixedly connected between piston plate 17 and housing 16. The bottom of wedge-shaped push block 18 contacts the outer wall of double-headed fan-shaped extrusion wheel 9 located in front of workbench 1. When motor 235 drives the double-headed fan-shaped extrusion wheel 9 to rotate, the wedge-shaped pusher block 18 pushes the piston plate 217 to move up and down repeatedly along the inside of the housing 316. Then, it repeatedly draws air into the inside of the housing 212, causing the piston plate 13 to move up and down repeatedly. Then, under the connection of the connecting rod 14, it drives the lifting frame 11 to move up and down repeatedly, thereby pulling the shaft 14 to slide back and forth along the inclined groove 3. This allows the cutting wheel 5 to move closer to the plate when it moves down along the inclined groove 3 and move away from the plate when it moves up. This avoids friction during cutting, cools down the cutting wheel 5, and extends its service life.

[0020] like Figure 1 , Figure 5 and Figure 6As shown, a water tank 24 is fixedly connected to the rear surface of the fixed plate 2 6 located behind the upper surface of the workbench 1.

A piston plate 4 32 is slidably connected inside the box 4.28, a spring 33 is fixedly connected between the piston plate 4 32 and the box 4.28, a wedge-shaped push block 2 34 is fixedly connected to the lower surface of the piston plate 4.24, and the bottom of the wedge-shaped push block 2 34 contacts the outer wall of the double-headed fan-shaped extrusion wheel 9 located behind the upper surface of the workbench 1. When the double-headed fan-shaped extrusion wheel 9 rotates, it will squeeze the piston plate 32 repeatedly along the inside of the housing 28 through the wedge-shaped push block 34. Then, gas can be filled into the water storage tank 24 through the one-way exhaust valve 30, which will drive the piston plate 27 to descend and squeeze the water storage tank 24 to drain a certain amount of water. The discharged water will be sprayed onto the cutting wheel 5 through the nozzle 37 for cooling effect. When the piston plate 32 rebounds, it will take in air through the one-way intake valve 29. The water storage tank 24 can be connected to an external water pump for water pumping through the one-way water pumping pipe 26. When adding water, the exhaust pipe 31 is removed.
