Description

Technical Field

[0001] This utility model relates to the technical field of quartz stone slab production equipment, specifically to a dust-proof cutting device for processing quartz stone slabs. Background Technology

[0002] Quartz stone slabs, also known as artificial stone slabs, are widely used in kitchens, bathrooms, countertops, and building walls. As a green and environmentally friendly decorative material, they are loved by users both at home and abroad.

[0003] The production of quartz stone slabs involves several processes, including mixing, feeding, stirring, and color matching; premixing multiple colors; mold placement; vacuum pressing; drying and curing; cooling; rough grinding; cutting; fine grinding; and film packaging. The cutting process removes excess material beyond the slab's planar dimensions, shaping the quartz stone slabs into the desired form and size. However, this cutting process generates a large amount of dust. If not collected promptly, this dust can spill over, severely polluting the production environment and endangering the health of workers.

[0004] Based on this, CN 216634927 U discloses a dust-proof cutting device for quartz stone processing, which includes a workbench, a vacuum cleaner, and a suction pipe. Two vacuum cleaners are symmetrically installed on both sides of the bottom of the workbench. The suction end of the vacuum cleaner is equipped with a suction pipe, and a dust collection hood is installed at one end of the suction pipe. This device, through the arrangement of a dust baffle, vacuum cleaner, suction pipe, and dust collection hood, uses the dust baffle to block the dust generated during the cutting process, and the vacuum cleaner creates negative pressure inside the dust collection hood to suck away the dust through the suction pipe, aiming to fully absorb the generated dust, thereby maintaining a clean working environment and protecting the health of the workers. However, the following problems still exist: the dust collection hood is a fixed structure, meaning its position is fixed. However, quartz stone slabs are usually large in size, resulting in a large cutting station, and the dust-proof effect of the fixed dust collection structure needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a dust-proof cutting device for quartz stone slab processing that is structurally sound and reliable in use. It solves the problem of poor dust-proof effect of fixed dust collection structures by adopting a mobile dust collection structure to achieve point-to-point timely dust collection, thereby further enhancing the pollution prevention effect.

[0006] The technical solution of this utility model is: A dust-proof cutting device for processing quartz stone slabs includes a U-shaped support frame, a cutting motor, and a cutting blade connected to the output shaft of the cutting motor. The key technical features are: the U-shaped support frame has a horizontal support roller conveyor inside, which is composed of multiple Y-axis support rollers; the left and right side walls of the U-shaped support frame are respectively equipped with slab posture correction mechanisms; two front and rear columns are fixed to the top of the left and right side walls of the U-shaped support frame, supporting two left and right X-axis linear modules; a Y-axis linear module is connected between the sliders of the two X-axis linear modules. The slider of the Y-axis linear module is connected and fixed to a rotary motor. The output shaft of the rotary motor faces downward and is connected and fixed to a lifting cylinder. A right-angle frame is fixed to the lower end of the cylinder rod of the lifting cylinder. The cutting motor is fixed to the vertical plate of the right-angle frame. An extension plate is fixed to the edge of the horizontal plate of the right-angle frame, and a dust collection hood is fixed to the extension plate. The outlet pipe of the dust collection hood is a retractable flexible pipe. The retractable flexible pipe passes through the guide ring at the top of the Y-axis linear module and is connected to a vacuum cleaner fixed to the outside of the U-shaped support frame. The bottom of the U-shaped support frame is equipped with a lifting mechanism corresponding to the quartz stone slab.

[0007] The dust-proof cutting device for quartz slab processing described above includes a slab posture correction mechanism comprising two sets of horizontal pushing cylinders fixed to the left and right side walls of a U-shaped support frame, and a push plate located at the end of the telescopic rod of each horizontal pushing cylinder. The push plate is staggered with the Y-axis support roller of the horizontal support roller track.

[0008] The dust-proof cutting device for quartz slab processing described above includes a vacuum chamber fixed to the inner bottom surface of the U-shaped support frame and a vacuum generator connected to the vacuum chamber. The lifting mechanism includes multiple lifting cylinders fixed to the top surface of the vacuum chamber. A vacuum suction cup is fixed to the upper end of the cylinder rod of the lifting cylinder. The air extraction port of the vacuum suction cup is connected to the vacuum chamber via a pipeline.

[0009] The dust-proof cutting device for quartz stone slab processing described above has a first infrared sensor and a second infrared sensor spaced apart along the length of the U-shaped support frame on the top surface of the vacuum chamber for detecting whether the quartz stone slab is in place.

[0010] In the aforementioned dust-proof cutting device for quartz slab processing, a transmission mechanism is provided between the ends of the roller shafts of each Y-axis support roller of the horizontal support roller track, and the end of the roller shaft of the first Y-axis support roller is connected and fixed to the output end of the drive motor reducer.

[0011] The dust-proof cutting device for quartz slab processing described above has multiple support columns at the bottom of the U-shaped support frame.

[0012] The beneficial effects of this utility model are: 1. The dust collection hood is installed on the right-angle frame where the cutting motor is located. When the cutting motor drives the cutting blade to perform the cutting operation, the dust collection hood directly sucks up the dust nearby. This mobile dust collection structure solves the problem of poor dust prevention effect of the fixed dust collection structure, has good timeliness, and further enhances the pollution prevention effect.

[0013] 2. The quartz stone slabs are bidirectionally pushed by a slab posture correction mechanism to concentrate them in the middle of the horizontal support roller conveyor, thereby achieving position correction before cutting and ensuring cutting accuracy.

[0014] 3. To avoid interference with the horizontal support roller conveyor during cutting, a lifting mechanism is used to lift the plate to a certain height. After cutting, the plate is lowered onto the upper surface of the horizontal support roller conveyor by the lifting mechanism and then conveyed to the next process by the horizontal support roller conveyor, which saves time and effort.

[0017] The present invention will be described in detail with reference to the accompanying drawings.

[0018] like Figures 1-3 As shown, the dust-proof cutting device for processing quartz stone slabs includes a U-shaped support frame 3, a cutting motor 9, and a cutting blade 10 connected to the output shaft of the cutting motor 9.

[0019] The U-shaped support frame 3 has a horizontal support roller conveyor 12 inside, which is composed of multiple Y-axis support rollers. In this embodiment, a transmission mechanism (omitted in the figure) is provided between the roller shaft ends of each Y-axis support roller of the horizontal support roller conveyor 12, and the roller shaft end of the first Y-axis support roller is connected and fixed to the output end of the drive motor reducer (omitted in the figure). The bottom of the U-shaped support frame 3 has multiple support columns 21.

[0020] The left and right side walls of the U-shaped support frame 3 are respectively provided with a plate posture correction mechanism. In this embodiment, the plate posture correction mechanism includes two sets of left and right horizontal pushing cylinders 23 fixed to the left and right side walls of the U-shaped support frame 3, and a push plate 13 provided at the end of the telescopic rod of each horizontal pushing cylinder. The push plate 13 is arranged alternately with the Y-direction support roller of the horizontal support roller conveyor 12.

[0021] The top of the left and right side walls of the U-shaped support frame 3 are fixed with two front and rear columns 2, which support two left and right X-direction linear modules 1. A Y-direction linear module 4 is connected between the sliders of the two X-direction linear modules 1. The slider of the Y-direction linear module 4 is connected and fixed to a rotary motor 5. The output shaft of the rotary motor 5 faces downward and is connected and fixed to a lifting cylinder 6. A right-angle frame 7 is fixed to the lower end of the cylinder rod of the lifting cylinder 6. The cutting motor 9 is fixed to the upright plate of the right-angle frame 7. An extension plate is fixed to the edge of the horizontal plate of the right-angle frame 7, and a dust collection hood 8 is fixed to the extension plate. The outlet pipe of the dust collection hood 8 is a retractable flexible pipe 24. The retractable flexible pipe 24 passes through the guide ring at the top of the Y-direction linear module 4 and is connected to a vacuum cleaner 22 fixed to the outside of the U-shaped support frame 3.

[0022] The bottom of the U-shaped support frame 3 is equipped with a lifting mechanism corresponding to the quartz stone slab 16. In this embodiment, a vacuum chamber 14 and a vacuum generator 20 connected to the vacuum chamber 14 are fixed to the inner bottom surface 11 of the U-shaped support frame 3. The lifting mechanism includes multiple lifting cylinders 15 fixed to the top surface of the vacuum chamber 14. A vacuum suction cup 19 is fixed to the upper end of the cylinder rod of the lifting cylinder 15. The suction port of the vacuum suction cup 19 is connected to the vacuum chamber 14 via a pipeline. The top surface of the vacuum chamber 14 is provided with a first infrared sensor 17 and a second infrared sensor 18 at intervals along the length of the U-shaped support frame 3 for detecting whether the quartz stone slab 16 is in place.

[0023] Working principle: 1. During operation, the quartz stone slab 16 is conveyed to the U-shaped support frame 3 through the starting end of the horizontal support roller conveyor 12. When the front end of the quartz stone slab 16 passes above the first infrared sensor 17, the horizontal support roller conveyor 12 stops after a set delay. The left and right sets of horizontal pushing cylinders 23 of the slab posture correction mechanism move relative to each other. The push plate 13 at the end of the cylinder rod of the horizontal pushing cylinder pushes the quartz stone slab 16 to correct its position to the middle position in the width direction of the horizontal support roller conveyor 12.

[0024] 2. Restart the horizontal support roller conveyor 12 to drive the front end of the quartz stone slab 16 to the top of the second infrared sensor 18. After a set delay, the horizontal support roller conveyor 12 stops and the quartz stone slab 16 reaches the cutting area.

[0025] 3. Start the lifting cylinder 15. The cylinder rod rises so that each vacuum suction cup 19 contacts the lower surface of the quartz stone slab 16. Start the vacuum generator 20. The vacuum suction cup 19 sucks up the quartz stone slab 16. The cylinder rod of the lifting cylinder 15 continues to extend outward and lift the quartz stone slab 16.

[0026] 4. Start the two X-axis linear modules 1, which drive the Y-axis linear module 4, rotary motor 5, lifting cylinder 6, right-angle frame 7, cutting motor 9 and cutting blade 10 to the top of the Y-axis straight edge of the quartz stone slab 16. The Y-axis linear module 4 drives the component below its slider to reach one end of the Y-axis. The cylinder rod of the lifting cylinder 6 extends downward. At the same time, the cutting motor 9 drives the cutting blade 10 to rotate. The Y-axis linear module 4 drives the cutting blade 10 to move from one end of the slab to the other end, thereby cutting the Y-axis straight edge of the quartz stone slab 16.

[0027] 5. After cutting, the cylinder rod of the lifting cylinder 6 rises, and the cutting blade moves away from the slab. The rotary motor 5 drives the lifting cylinder 6, the right-angle frame 7, the cutting motor 9, and the cutting blade 10 to rotate 90 degrees, and restarts the two X-direction linear modules 1 and the lifting cylinder 6, driving the cutting blade 10 to cut along the X-direction straight edge of the quartz stone slab 16, thus achieving the cutting of the X-direction straight edge of the quartz stone slab 16.

[0028] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
