Description

Technical Field

[0001] The invention belongs to the technical field of furniture processing, and in particular relates to a laser cutting machine for furniture production. Background Art

[0002] Furniture refers to various fixed or movable devices and accessories used in indoor spaces, designed to provide comfort, functionality or decorative functions. It includes various items such as tables, chairs, beds, cabinets, sofas, etc., which are usually used to support daily activities such as sitting, sleeping, storing items, etc. Furniture usually uses wood as the main material. In the furniture production process, laser cutting machines are usually used to cut materials (such as wood boards, synthetic boards, etc.) into the required shape and size through laser beams. Laser cutting can achieve complex design patterns, greatly improving production efficiency.

[0003] In the production process of existing furniture, laser cutting machines are usually used for processing. The laser cutting machines are used to cut the designed patterns on the wooden boards. However, after the existing laser cutting machines cut the wooden boards, the cut surfaces are usually blackened, which requires them to be removed separately in the subsequent processing steps. At the same time, most laser cutting machines are manually loaded, and after cutting the wooden boards, the remaining waste needs to be manually processed, which not only increases labor costs but also reduces production efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a laser cutting machine for furniture production.

[0005] The technical solution adopted to solve the above technical problems is: a laser cutting machine for furniture production, comprising a bottom plate, a feeding mechanism is fixedly installed on one side of the top front end of the bottom plate, and a material transport mechanism is fixedly installed at the center of the top front end of the bottom plate; A feeding mechanism is fixedly installed on the other side of the top of the bottom plate near the material transport mechanism, a chassis is fixedly installed on the other side of the top rear end of the bottom plate, and a material transfer mechanism is installed on the top of the chassis; A laser cutting mechanism is installed at the top rear end of the chassis, a smoke blowing mechanism is fixedly installed at the rear end of the chassis, and a smoking mechanism is installed inside the chassis and below the laser cutting mechanism; A material pushing mechanism is installed at the front end of the chassis, and a plurality of furniture plates are arranged on the material feeding mechanism.

[0006] Furthermore, the feeding mechanism includes a support frame fixedly connected to one side of the front end of the top of the base plate, the top of the support frame is fixedly connected to the feeding frame, a plurality of pulleys are installed on the bottom inner surface of the feeding frame, a first limiting groove is provided at the bottom of the feeding frame, a movable groove is provided at the bottom of the feeding frame and close to the top of the first limiting groove, a discharge port is provided on one side of the feeding frame, both sides of the center of the support frame are rotatably connected to the rotating shaft, the front and rear ends of the outer walls of the two rotating shafts are fixedly connected to sprockets, a chain is installed between every two of the sprockets, a connecting frame is fixedly connected between the two chains, a plurality of pushing heads are fixedly connected to the top of the connecting frame, a first motor is installed on the other side of the rear end of the support frame, and the front end of the output shaft of the first motor is fixedly connected to the rear end of one of the rotating shafts.

[0007] Through the above technical solution, the staff places multiple furniture panels into the loading rack and starts the first motor. The first motor drives the rotating shaft connected to it to rotate through the output shaft, thereby driving the two sprockets connected to it to rotate, and cooperating with the remaining two sprockets to drive the two meshing chains to rotate, thereby driving the connecting frame to slide into the first limiting groove, and then driving the multiple push heads to slide into the movable groove. Since the height of the multiple push heads is less than the thickness of the bottom furniture panel, when the multiple push heads move, they drive the bottom furniture panel to move on the multiple pulleys, and finally move to the material transport mechanism through the discharge port.

The hydraulic cylinder is started, and the hydraulic cylinder drives the connecting plate to move downward through the piston, thereby driving the multiple first suction cups to move downward, so that the multiple first suction cups just fit with the top of the furniture board. At the same time, the first vacuum pump is started, and the first vacuum pump sucks air to the first suction pipe through the first connecting pipe, so that the multiple first suction cups suck air to the furniture board, thereby achieving adsorption and fixation of the furniture board. Then the second motor is started to drive the first gear to mesh and rotate on the first rack, thereby driving the first slide to slide on the two first guide rails, and then driving the furniture board to move in the direction of the material transfer mechanism, automatically completing the material transfer process, which not only improves processing efficiency, but also reduces labor costs.

[0012] A first material receiving cabinet is arranged inside the chassis and close to the front end of the smoking mechanism, and a second material receiving cabinet is arranged inside the chassis and close to the bottom of the smoking mechanism.

[0013] Through the above technical solution, the first material collecting cabinet collects the finished products of the furniture panels, and the second material collecting cabinet collects the waste materials remaining after the furniture panels are cut. At the same time, both the first material collecting cabinet and the second material collecting cabinet can be drawn out to discharge materials, and the operation is simple.

During the movement of the movable frame, the two rollers are driven to slide on the corresponding arc-shaped slide grooves. When the sliding arc-shaped slide groove reaches the lowest point, the first positioning frame is driven to drop a certain distance under the limit of multiple limit columns. At this time, the second positioning frame is just moved to the top of the first positioning frame, so that the two avoid each other, and the synchronous belt continues to drive. When the first positioning frame and the second positioning frame exchange their initial positions, the furniture panels on the first positioning frame are ready for laser cutting, and the second positioning frame is ready to receive the furniture panels delivered by the feeding mechanism. When the cutting of the furniture panels on the first positioning frame is completed and the furniture panels to be processed are placed on the second positioning frame, the synchronous belt is driven again, and the first positioning frame and the second positioning frame exchange positions again. The pushing mechanism pushes the remaining waste materials on the first positioning frame into the second receiving cabinet, and the laser cutting mechanism cuts the furniture panels on the second positioning frame. The furniture panels are continuously transferred according to the same principle, and the remaining waste materials are discharged during cutting. At the same time, the furniture panels to be processed can also be loaded. There is no need to wait at each workstation, which greatly improves the processing efficiency.

[0016] Furthermore, the laser cutting mechanism includes second mounting frames that are fixedly connected to the rear ends of both sides of the outer wall of the chassis, the tops of the two second mounting frames are fixedly connected to second guide rails, a second slide is slidably connected between the two second guide rails, a second rack is fixedly connected to a top side of one of the second mounting frames, a fourth motor is fixedly installed on the bottom end of one side of the second slide, a second gear is fixedly connected to the outer wall of the output shaft of the fourth motor, the second gear is meshed with the second rack, a lead screw is installed between the second slides, a fifth motor is fixedly installed on the top end of one side of the second slide, one end of the output shaft of the fifth motor is fixedly connected to one end of the lead screw, a nut seat is installed on the lead screw, an electric push rod is fixedly installed on the top of the nut seat, and a laser cutting head is fixedly installed on the bottom end of the electric push rod piston.

[0017] Through the above technical solution, when cutting furniture panels, the electric push rod is started to drive the laser cutting head to move downward to a height that can be cut, and then the fourth motor is started to drive the second gear to mesh and rotate on the second rack. At the same time, the fifth motor is started to drive the lead screw to rotate, thereby driving the nut seat to move, thereby realizing the laser cutting head to move forward, backward, left and right, and to achieve different patterns on the furniture panels.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention designs a loading mechanism, a material transporting mechanism, a material pushing mechanism and a material transfer mechanism. The whole process does not require the intervention of staff, and each workstation can efficiently complete the designated work. In the material transfer mechanism, two positioning frames automatically complete the loading and pushing of materials respectively, and assist in the subsequent laser cutting. Each workstation does not need to wait, and the processing efficiency is high. (2) The present invention designs a smoke blowing mechanism and a smoking mechanism.

The toxic smoke generated during laser cutting is extracted by the smoking mechanism and filtered and discharged to prevent toxic gases from endangering the staff. BRIEF DESCRIPTION OF THE DRAWINGS

When the furniture board 11 on the first positioning frame 607 is cut, and the furniture board 11 to be processed is placed on the second positioning frame 610, the synchronous belt 612 is driven again, and the first positioning frame 607 and the second positioning frame 610 exchange positions again. The pushing mechanism 10 pushes the remaining waste material on the first positioning frame 607 into the second receiving cabinet 52, and the laser cutting mechanism 7 cuts the furniture board 11 on the second positioning frame 610. The same principle continues to transfer the furniture board 11, and the remaining waste material is discharged during cutting. At the same time, the furniture board 11 to be processed can also be loaded, and each station does not need to wait, which greatly improves the processing efficiency.

A third connecting pipe 806 is fixedly connected between the first air pump 805 and the air pipe 803. While cutting the furniture board 11, the first air pump 805 is started, so that the first air pump 805 blows air to the air pipe 803 through the third connecting pipe 806, thereby blowing air to the cutting point through the plurality of nozzles 802, which can blow away the smoke and charcoal ash generated by the laser cutting head 711 during cutting, and reduce their deposition on the cutting surface of the furniture board 11. At the same time, the injection of gas can reduce the local combustion of the cutting surface of the furniture board 11, thereby reducing the scorching and blackening of the cutting surface, and greatly improving the quality of the finished product after furniture cutting.

[0035] like Figure 1-Figure 13As shown, a smoking mechanism 9 is installed inside the chassis 5 and near the lower position of the laser cutting mechanism 7. The smoking mechanism 9 includes a fixing plate 901 fixedly connected to the center of the bottom inner surface of the chassis 5. The rear end inner surface of the chassis 5 and the top of the fixing plate 901 are fixedly connected with trapezoidal suction heads 902. One side of the two trapezoidal suction heads 902 are fixedly connected with pipe heads 903. A fourth connecting pipe 904 is fixedly connected between the two pipe heads 903. The bottom inner surface of the chassis 5 and the front end of the fixing plate 901 are fixedly connected with the fourth connecting pipe 904. A filter box 905 is connected, one end of the fourth connecting pipe 904 passes through the inner top of the filter box 905, and two second limiting grooves 906 are provided on the inner surfaces of the front and rear ends of the filter box 905, and a fixed frame 907 is slidably connected between each two second limiting grooves 906, and a fixed frame door 9071 is fixedly connected to one side of the two fixed frames (907), and the inner walls of the two fixed frames 907 are fixedly connected to rubber sealing rings 908, and removable filter plates 908 are installed in the two rubber sealing rings 908. 09, a second air pump 910 is fixedly installed on the inner surface of the bottom of the chassis 5 and close to one side of the filter box 905, a fifth connecting pipe 911 is fixedly connected between the second air pump 910 and the filter box 905, and a smoke exhaust pipe 912 is fixedly connected to the second air pump 910. When cutting the furniture board 11, the second air pump 910 is started, so that the second air pump 910 exhausts air from the filter box 905 through the fifth connecting pipe 911, and then exhausts air from the two trapezoidal suction heads 902 through the fourth connecting pipe 904, so that the two The trapezoidal suction head 902 extracts the smoke generated during the laser cutting of the furniture board 11, and draws it into the filter box 905 through the fourth connecting pipe 904, and filters it through two filter plates 909. Finally, the filtered gas is discharged to the outside through the smoke exhaust pipe 912 to prevent the smoke from damaging the health of the staff. The staff can pull the fixed frame door 9071 to remove the two filter plates 909 for cleaning, and tighten them through the rubber sealing ring 908 when reinstalling to improve their service life and filtering effect.

[0036] like Figure 1-Figure 14 As shown, a pushing mechanism 10 is installed at the front end of the chassis 5, and a plurality of furniture panels 11 are provided on the feeding mechanism 2. The pushing mechanism 10 includes a limiting plate 1001 fixedly connected to the front end of the top of the chassis 5, and a fourth mounting frame 1002 is fixedly connected to the top of the front end of the chassis 5. A cylinder 1003 is fixedly installed on the top of the fourth mounting frame 1002, and a push plate 1004 is fixedly connected to the rear end of the piston of the cylinder 1003. The push plate 1004 is slidably connected to the limiting plate 1001. The cylinder 1003 is started, and the cylinder 1003 pushes the push plate 1004 through the piston, so that the push plate 1004 pushes the waste remaining after cutting on the transfer mechanism 6, and pushes the waste into the second material receiving cabinet 52.

[0037] The working principle of this embodiment is as follows: the staff puts a plurality of furniture plates 11 into the loading rack 202, starts the first motor 212, drives the two sprockets 208 to rotate through the rotating shaft 207 connected thereto, cooperates with the remaining two sprockets 208, drives the two meshing chains 209 to rotate, thereby driving the connecting rack 210 to slide into the first limiting groove 204, and then drives the plurality of push heads 211 to slide into the movable groove 205. Since the height of the plurality of push heads 211 is less than the thickness of the bottom furniture plate 11, when the plurality of push heads 211 move, they drive the bottom furniture plate 11 to move on the plurality of pulleys 203, and finally move to the conveying roller assembly 302 through the discharge port 206; When the furniture board 11 is transported by the conveying roller assembly 302 to fit with the baffle 303, the hydraulic cylinder 408 is started to drive the connecting plate 409 to move downward, thereby driving the plurality of first suction cups 410 to move downward, so that the plurality of first suction cups 410 just fit with the top of the furniture board 11, and at the same time the first vacuum pump 412 is started to make the plurality of first suction cups 410 suck air from the furniture board 11 through the first connecting pipe 413 and the first suction pipe 411, thereby achieving adsorption and fixation of the furniture board 11, and then the second motor 406 is started to drive the first gear 407 to mesh and rotate on the first rack 405, thereby driving the first slide 404 to slide on the two first guide rails 403, and then driving the furniture board 11 to move to the top of the first positioning frame 607, and then the furniture board 11 is placed on the first positioning frame 607 through the hydraulic cylinder 408; Start the second vacuum pump 618, and evacuate the multiple second suction cups 615 through the second connecting pipe 620 and the second suction pipe 616 connected thereto, so as to achieve the adsorption and fixation of the furniture plate 11, and then start the third motor 613 to drive the pulley 611 connected thereto to rotate, and cooperate with the remaining multiple pulleys 611 to drive the synchronous belt 612 to drive, and then drive the movable frame 605 and the second positioning frame 610 to move towards each other. During the movement of the movable frame 605, the two rollers 609 are driven to slide on the corresponding arc-shaped slide groove 603. When the sliding arc-shaped slide groove 603 reaches the lowest point, it is limited by multiple limit columns 606 and drives the first positioning frame 607 to descend a certain distance. When the second positioning frame 610 is moved to the top of the first positioning frame 607, the two avoid each other. When the synchronous belt 612 continues to drive, the first positioning frame 607 and the second positioning frame 610 exchange their initial positions. At this time, the furniture board 11 on the first positioning frame 607 is located below the laser cutting head 711. The electric push rod 710 is started to drive the laser cutting head 711 to move downward to a height that can be cut. Then, the second slide 703 and the nut seat 709 are moved to drive the laser cutting head 711 to move forward, backward, left and right, so that different patterns can be cut on the furniture board 11. The finished product after cutting falls into the first material receiving cabinet 51. When the furniture board 11 is laser cut, the first air pump 805 is started, and air is blown to the air pipe 803 through the third connecting pipe 806, so that air is blown to the cutting point through multiple nozzles 802, so that smoke and carbon ash generated by the laser cutting head 711 during cutting can be blown away. At the same time, the second air pump 910 is started, and air is evacuated from the filter box 905 through the fifth connecting pipe 911, so that air is evacuated from the two trapezoidal suction heads 902 through the fourth connecting pipe 904, so that the two trapezoidal suction heads 902 can evacuate the smoke generated by the laser cutting of the furniture board 11, and the smoke is pumped into the filter box 905 through the fourth connecting pipe 904, and filtered through the two filter plates 909, and finally the filtered gas is discharged to the outside through the smoke exhaust pipe 912; At the same time, the second positioning frame 610 is ready to receive the furniture board 11 delivered by the feeding mechanism 4. After the cutting of the furniture board 11 on the first positioning frame 607 is completed, the synchronous belt 612 is driven again, and the first positioning frame 607 and the second positioning frame 610 exchange positions again. The first positioning frame 607 drives the waste to move close to the position of the pushing mechanism 10, and the cylinder 1003 is started. The push plate 1004 is pushed by the piston, so that the push plate 1004 pushes the waste remaining after cutting on the first positioning frame 607, and pushes the waste into the second material receiving cabinet 52. The waste remaining after cutting on the first positioning frame 607 is pushed into the second material receiving cabinet 52. After the waste is cleaned, the furniture board 11 to be processed is quickly adsorbed and fixed, and the same principle is used to continue to perform material transfer, laser cutting and pushing steps on several furniture boards 11.
