Description

Background Art

Aluminum veneers are commonly used building materials and are mainly used for indoor and outdoor decoration, such as building exterior walls, commercial podiums, ceilings, etc. Because the area of the decoration site is not fixed, and aluminum veneers are usually produced in standard fixed sizes, during the installation and laying of aluminum veneers, it is easy to need to cut the aluminum veneers because the area of the final laying area is smaller than the area of a single aluminum veneer. Therefore, before the installation and laying of aluminum veneers, the corresponding aluminum veneers will be pre-cut using laser cutting equipment according to the area of the installation site.

It has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, low processing costs, etc., and gradually improves or replaces traditional metal cutting process equipment. However, some thinner aluminum veneers are in a rolled state before cutting, and are prone to bending when unfolded. They need to be flattened before cutting. Otherwise, it is easy to cause the cutting effect to be unsatisfactory and affect the cutting accuracy of the aluminum veneer. In addition, aluminum veneers of different thicknesses require different laser cutting parameters. For aluminum veneers with thicker thicknesses, higher power lasers and longer cutting times are required.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

First embodiment

As shown in Figures 1 to 5, an embodiment of the present invention is shown. By setting a rotating roller 24 and a pressing roller 27 to level the aluminum veneer, the aluminum veneer is prevented from being in a bent state during cutting, which affects laser cutting and further affects the cutting accuracy of the aluminum veneer.

A cutting device for aluminum veneer comprises a laser cutting machine body 1, a leveling device 2 is fixedly installed on the left side of the top of the laser cutting machine body 1, a positioning component 3 is slidably installed on the top of the laser cutting machine body 1, and dust collecting devices 4 are fixedly installed at both ends of the inside of the laser cutting machine body 1;

The laser cutting machine body 1 includes a base frame 11, both ends of the side of the base frame 11 are provided with movable grooves 12, both sides of the upper end of the base frame 11 are fixedly installed with sliding rails 15, the top of the sliding rail 15 is slidably installed with a gantry 14, the inside of the gantry 14 is slidably installed with a cutting frame 17, the bottom of the cutting frame 17 is provided with a cutting component 18, both sides of the upper end of the inner wall of the base frame 11 are provided with sliding grooves 13, both sides of the right end of the base frame 11 are fixedly installed with hydraulic telescopic rods 16, and both ends of the inside of the base frame 11 are fixedly installed with support components 5;

Among them, the cutting frame 17 slides on the top of the gantry 14 through a rack transmission. The gear rack transmission is a common form of mechanical transmission, which consists of a rack and a vertically installed gear. The cutting frame 17 is equipped with an electric motor inside. The electric motor is driven by power supply to rotate the gear inside the cutting frame 17. The gear engages the rack inside the gantry 14 during the rotation process, and the motion is converted into linear motion under the action of the rack, thereby controlling the horizontal movement of the cutting frame 17 on the gantry 14 and being protected by a corrugated rubber sleeve.

Through the hydraulic telescopic rod 16, the positioning component 3 is controlled to move inside the sliding groove 13. When the leveling device 2 levels the aluminum veneer, the positioning component 3 moves to the right side of the leveling device 2, so that the aluminum veneer moves to the top of the positioning component 3, and the aluminum veneer moves to the right side of the base frame 11, so that the cutting component 18 shears the aluminum veneer.

The leveling device 2 includes a support roller 21, which is fixedly mounted at one end of the base frame 11. Support frames 22 are fixedly mounted at both ends of the support roller 21. A pressing cylinder 26 is fixedly mounted on the top of the support frame 22. A pressing roller 27 is provided at the bottom of the pressing cylinder 26. The pressing roller 27 is slidably mounted inside the upper end of the support frame 22.

Among them, a laser rangefinder 25 is fixedly installed on the side of the support frame 22, a positioning plate 28 is fixedly installed on the side of the pressing roller 27, the positions of the laser rangefinder 25 correspond to the positioning plate 28, a leveling motor 23 is fixedly installed on the right side of the support frame 22, a rotating roller 24 is fixedly installed on the side of the leveling motor 23, and the rotating roller 24 and the pressing roller 27 are rotatably installed inside the support frame 22.

The thickness of the aluminum sheet is determined by the distance between the laser rangefinder 25 and the positioning plate 28, and then the corresponding cutting mode is automatically adjusted to convert it into corresponding cutting parameters.

Among them, thin aluminum single plate (1-3 mm) usually requires lower laser power, and at this time, only the first laser cutting head 187 is working.

Medium-thick aluminum veneer (4-6 mm) requires a medium-power laser. At this time, the first laser cutting head 187 and the second laser cutting head 188 work together to ensure the depth and quality of the cutting.

Thick aluminum veneer (7 mm or more): A high-power laser is required. At this time, the first laser cutting head 187 and the second laser cutting head 188 work together to penetrate the thicker material and ensure uniform cutting effect.

As shown in Figure 4, the support assembly 5 includes two support plates 51, and a plurality of engaging grooves 54 are provided on the top of the support plates 51. A lifting motor 52 is fixedly installed between the two support plates 51. A lifting screw 53 is fixedly installed on the bottom of the lifting motor 52.

A ball 57 is rotatably installed on the top of the fixing block 56. The fixing block 56 is embedded inside the engaging groove 54, and the fixing block 56 is movable inside the positioning assembly 3.

By setting the fixed block 56 and the ball 57, when the aluminum veneer moves to the top of the support bar 35, the lifting motor 52 is used to control the lifting screw 53 to rotate, so that the lifting frame 55 rises, and the fixed block 56 and the ball 57 are moved to the top of the support bar 35. After the aluminum veneer is leveled, it moves to the top of the ball 57, and the ball 57 is used to prevent the aluminum veneer from sliding directly on the top of the support bar 35, which causes scratches on the surface of the aluminum veneer and affects the quality of the aluminum veneer production.

Second embodiment

As shown in Figures 1 to 6, an embodiment of the present invention is based on the first embodiment. The aluminum veneer enters the top of the ball 57, and through the action of the bidirectional motor 310, the bidirectional screw 311 is rotated, and the sliding brackets 36 move towards each other, so that the positioning wheels 37 are close to each other, and the aluminum veneer is limited to avoid deviation of the aluminum veneer after being leveled, and the position of the aluminum veneer is corrected, so that the aluminum veneer can be cut more accurately, thereby improving the cutting effect of the aluminum veneer.

The second embodiment is further optimized relative to the first embodiment in that the positioning assembly 3 includes a sliding frame 31, a fixed frame 32 is fixedly installed on the top of the sliding frame 31, a plurality of support bars 35 are fixedly installed inside the fixed frame 32, a transmission motor 33 is fixedly installed at one end of the fixed frame 32, a moving roller 34 is fixedly installed on the side of the transmission motor 33, the moving roller 34 is rotatably installed inside one end of the fixed frame 32, and two limit rods 38 are fixedly installed at both ends of the interior of the sliding frame 31.

The limiting rod 38 is located below the supporting bar 35 , and a bottom frame 39 is fixedly installed in the middle of the sliding frame 31 . The bottom frame 39 is located between the two limiting rods 38 and below the supporting bar 35 .

The support bars 35 are evenly distributed inside the fixed frame 32, and the limit rods 38 and the bottom frame 39 are located below the support bars 35 to avoid interference between the limit rods 38 and the bottom frame 39 when the fixed block 56 and the ball 57 are raised or lowered, so that the fixed block 56 and the ball 57 pass between the support bars 35 and move to the inside of the fixed frame 32.

Among them, a bidirectional motor 310 is fixedly installed in the middle of the bottom frame 39, and a bidirectional screw 311 is fixedly sleeved inside the bidirectional motor 310. The bidirectional screw 311 is rotatably installed inside the bottom frame 39. Sliding brackets 36 are threadedly installed at both ends of the bidirectional screw 311. The sliding bracket 36 is slidably installed inside the bottom frame 39. Positioning wheels 37 are rotatably installed on both sides of the top of the sliding bracket 36, and the positioning wheels 37 are slidably installed inside the fixed frame 32.

Through the action of the bidirectional motor 310, the bidirectional screw 311 is rotated, so that the sliding bracket 36 moves toward each other, and the positioning wheel 37 limits the aluminum single plate.

The sliding frame 31 is slidably installed inside the sliding groove 13 , the moving roller 34 is rotatably installed on the right side of the rotating roller 24 , and the side of the sliding frame 31 away from the moving roller 34 is fixedly connected to the hydraulic telescopic rod 16 .

Third embodiment

As shown in Figures 1 to 6 and 8, an embodiment of the present invention is shown. On the basis of the second embodiment, the pressing cylinder 26 controls the pressing roller 27 to descend to level the aluminum veneer. While the aluminum veneer is leveled, the thickness of the aluminum veneer is detected by the laser rangefinder 25 and the positioning plate 28, and then the parameters required for cutting are automatically adjusted according to the thickness of the aluminum veneer, and the aluminum veneer is cut by the cutting component 18. At the same time, a first laser cutting head 187 and a second laser cutting head 188 are set to cut the aluminum veneer according to the thickness of the aluminum veneer, so as to avoid a long cutting time for thicker aluminum veneers. High-temperature laser cutting may cause thermal damage to the surface of the aluminum veneer, such as surface discoloration or burn marks.

The third embodiment is further optimized relative to the second embodiment in that the cutting assembly 18 includes a movable frame 181, which is movably mounted on the bottom of the cutting frame 17, a first laser cutting head 187 is fixedly mounted on the bottom of the movable frame 181, a rotating ring 182 is rotatably mounted on the upper end of the first laser cutting head 187, a transmission gear 185 is fixedly sleeved on the outer surface of the upper end of the rotating ring 182, a steering motor 183 is fixedly mounted on the left side of the movable frame 181, a driving gear 184 is fixedly mounted on the bottom of the steering motor 183, and the outer surface of the driving gear 184 is meshed with the outer surface of the transmission gear 185.

A movable frame 181 is provided to control the rotation of the driving gear 184, and the rotating ring 182 is rotated on the outer surface of the first laser cutting head 187 by transmitting the transmission gear 185, so that the second laser cutting head 188 automatically adjusts the direction along the preset cutting path, so that the second laser cutting head 188 performs secondary cutting along the cutting path of the first laser cutting head 187.

The driving gear 184 is rotatably mounted on the lower end of the cutting frame 17 , a connecting frame 186 is fixedly mounted on the side of the lower end of the rotating ring 182 , and a second laser cutting head 188 is fixedly mounted on one end of the connecting frame 186 .

When cutting a thicker aluminum veneer, a laser beam of a first processing power is emitted to the aluminum veneer through the first laser cutting head 187, and the aluminum veneer is laser cut a first number of times along a preset cutting path to cut a groove on the aluminum veneer. Then, the second laser cutting head 188 is controlled to emit a laser beam of a second processing power, and the laser beam is controlled to laser cut a second number of times along the preset cutting path to cut through the aluminum veneer, wherein the first power is greater than the second power, and when the first power is used for cutting, the groove is not cut through. Since double cutting is used, heat accumulation is less, which not only completes the cutting of the aluminum veneer, but also avoids discoloration or burn marks on the surface of the aluminum veneer caused by heat accumulation, thereby improving the cutting quality of the aluminum veneer.

Fourth embodiment

As shown in Figures 1 to 7, an embodiment of the present invention, during the process of cutting the aluminum veneer, a dust suction device 4 is provided to allow the exhaust fan to exhaust air and the air inlet 41 to suck air, so that the aluminum veneer is more closely attached to the top of the support bar 35, thereby preventing the aluminum veneer from shifting during laser cutting. At the same time, the cutting portion of the aluminum veneer is cooled, thereby improving the quality of the cutting of the aluminum veneer.

The fourth embodiment is further optimized relative to the third embodiment in that the dust collection device 4 includes an air inlet 41, a fixed box 42, a dust box 44, an exhaust fan and a filter 45. The air inlet 41 is fixedly installed at the upper end of the base frame 11, the fixed box 42 is fixedly installed at the bottom of the air inlet 41, the exhaust fan is arranged on the right side of the upper end of the fixed box 42, the filter 45 is fixedly installed on the side of the fixed box 42 and is located on the left side of the exhaust fan, the dust box 44 is slidably installed at the bottom of the fixed box 42, and the dust box 44 is movably installed inside the movable groove 12.

The air inlet 41 is used to expand the air intake area and reduce the suction force on the aluminum plate to avoid indentations on the surface of the aluminum plate due to excessive suction when the aluminum plate is on the top of the support bar 35. The suction fixes the aluminum plate while avoiding affecting its quality.

Working principle of the present invention: when in use, the positioning assembly 3 is controlled to move inside the sliding groove 13 through the hydraulic telescopic rod 16, and the positioning assembly 3 moves to the right side of the leveling device 2. At this time, the lifting motor 52 controls the lifting screw 53 to rotate, so that the lifting frame 55 rises, the fixed block 56 moves out of the inside of the embedded groove 54, and the top ball 57 is located above the support bar 35. The operator places the aluminum single plate on the top of the rotating roller 24 through the supporting roller 21. At this time, the pressing cylinder 26 controls the pressing roller 27 to descend, so that the pressing roller 27 is pressed to the surface of the aluminum single plate on the top of the rotating roller 24. The distance between the laser rangefinder 25 and the positioning plate 28 is used to judge the thickness of the aluminum single plate, and then the cutting device is automatically adjusted to the corresponding cutting mode to switch to the corresponding cutting parameters;

At the same time, the leveling motor 23 is started to rotate the rotating roller 24, and the aluminum veneer is leveled by the extrusion of the pressing roller 27. The leveled aluminum veneer is moved to the top of the ball 57 through the transmission of the moving roller 34, and the ball 57 prevents the aluminum veneer from sliding directly on the top of the support bar 35. The bidirectional motor 310 rotates the bidirectional screw 311, and the sliding bracket 36 moves toward each other, so that the positioning wheels 37 are close to each other, and the aluminum veneer is limited;

Subsequently, the lifting motor 52 controls the lifting screw 53 to rotate in the opposite direction, so that the lifting frame 55 descends, and the hydraulic telescopic rod 16 controls the positioning assembly 3 to move to the right end of the base frame 11, so as to facilitate the cutting assembly 18 to cut the aluminum veneer on the top of the support bar 35. The gantry 14 moves to the top of the aluminum veneer. At this time, the first laser cutting head 187 emits a laser beam of a first processing power to the aluminum veneer, and performs laser cutting of the aluminum veneer for the first number of cutting times along the preset cutting path to cut a groove on the aluminum veneer. Subsequently, the second laser cutting head 188 is controlled to emit a laser beam of a first processing power to the aluminum veneer. A laser beam of a second processing power controls the laser beam to perform laser cutting for a second number of cutting times along a preset cutting path to cut through the aluminum veneer, and when the cutting direction of the first laser cutting head 187 is changed, the movable frame 181 controls the driving gear 184 to rotate, and through the transmission gear 185, the rotating ring 182 is rotated on the outer surface of the first laser cutting head 187, so that the second laser cutting head 188 automatically adjusts its direction along the preset cutting path, so that the second laser cutting head 188 performs secondary cutting along the path cut by the first laser cutting head 187;

During the cutting process of the aluminum veneer, the dust collecting device 4 located inside the base frame 11 and at the bottom of the aluminum veneer works, so that the exhaust fan draws air, a certain negative pressure is generated inside the fixed box 42, and the air inlet 41 sucks air. Since the gas flow speed between the air inlet 41 and the aluminum veneer is fast, the air pressure will be reduced, and a slight suction force will be generated on the aluminum veneer, so that the aluminum veneer is more closely attached to the top of the support bar 35. At the same time, the cutting part of the aluminum veneer is cooled, thereby improving the cutting quality of the aluminum veneer.

In addition, during the flow of air, the cut dust will enter the interior of the fixed box 42 from the air inlet 41 along with the air flow, and will fall into the interior of the dust box 44 through the interception of the filter 45 and the gravity of the dust itself, and then be cleaned by taking out the dust box 44.

Finally, a few points should be explained: the drawings of the embodiments disclosed in the present invention only involve structures related to the embodiments disclosed in the present invention, and other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present invention can be combined with each other;

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
