Description

Technical Field

[0001] The invention belongs to the field of laser cutting, and in particular relates to a laser cutting device for producing flash evaporation equipment. Background Art

[0002] Flash evaporation involves hot air entering the dryer tangentially from the cyclone at the bottom of the dryer, generating a high-speed, swirling, upward airflow. The material to be dried is fed into the drying chamber by a feeder. The high-speed, swirling airflow and the agitator at the bottom cause the material to be continuously broken up, dispersed, boiled, and dried. Qualified material is carried out of the dryer's upper outlet by the airflow and captured as a dried product. Larger or more humid materials are intercepted by the grading weir plate located above the drying chamber and continue to dry further until they are carried out by the airflow.

[0003] Flash evaporation equipment primarily consists of a screw feeder, flash tank, swirl device, bag filter, and cyclone separator. These components are typically connected by pipes. During flash evaporation equipment production, circular holes must be cut into each tank to facilitate pipe connections. However, due to the large size of the components and the integrally molded housings, these holes must be cut after the housing is formed. Otherwise, any prematurely cut holes could affect the quality of the housing.

[0004] Due to the large size of the tank body, the existing method of cutting the tank shell is mostly done by manual handheld cutting machines. However, due to the curved surface of the tank body, it is difficult for workers to grasp the cutting angle, which is not only inefficient, but also may cause cutting deviations due to hand shaking of the workers, affecting the quality of the tank body.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0032] like Figures 1-6 As shown, a laser cutting device for flash evaporation equipment production provided by the present invention includes a base plate 1, a sliding plate 2 is slidably mounted on the base plate 1, a first servo motor 3 is fixedly mounted on the sliding plate 2, an output shaft of the first servo motor 3 is fixedly connected to a rotating shaft 11, one end of the rotating shaft 11 is fixedly connected to a mounting plate 4, an adjustable cutting mechanism 7 is mounted at an eccentric position on the side of the mounting plate 4, and the adjustable cutting mechanism 7 is used to cut the tank body;

[0033] A driving mechanism 9 is also installed on the bottom plate 1, and the driving mechanism 9 is used to drive the sliding plate 2 to move so that the adjustable cutting mechanism 7 is close to the tank body;

[0034] A fixing mechanism 6 is fixedly mounted on the bottom plate 1 , and the fixing mechanism 6 is used to fix the bottom plate 1 to the tank body without manual support, thereby reducing the workload of the staff.

[0035] When in use, the device is installed on the tank body through the fixing mechanism 6, and then the sliding plate 2 is driven to move by the driving mechanism 9, and the sliding plate 2 drives the mounting plate 4 and the adjustable cutting mechanism 7 to approach the surface of the tank body, and the first servo motor 3 is started. The first servo motor 3 drives the mounting plate 4 to rotate through the rotating shaft 11, and the mounting plate 4 drives the adjustable cutting mechanism 7 to rotate in a circle. At the same time, the adjustable cutting mechanism 7 is started, and the adjustable cutting mechanism 7 can perform circular cutting on the tank body. Compared with the manual cutting method in the prior art, the present invention adopts the cutting method of the mounting plate 4 plus the adjustable cutting mechanism 7, so that the cut circle is more standard, avoids the situation where the cutting deviation caused by manual cutting, thereby improving the cutting quality and improving the cutting efficiency.

[0036] The present invention provides a laser cutting device for flash evaporation equipment production. In this embodiment, the adjustable cutting mechanism 7 includes an adjustment mechanism, which is installed on the side of the mounting plate 4. A laser cutter 78 is installed at the output end of the adjustment mechanism. The adjustment mechanism is used to adjust the distance from the laser cutter 78 to the axis of the mounting plate 4, so that circles of different sizes can be cut.

[0037] The present invention provides a laser cutting device for flash evaporation equipment production. In this embodiment, the adjustment mechanism includes a slide groove 71 opened on the side of the mounting plate 4, and an adjustment block 75 is slidably installed inside the slide groove 71. The adjustment block 75 is the output end of the adjustment mechanism. An adjustment screw 73 is also rotatably installed inside the slide groove 71, and the adjustment screw 73 and the adjustment block 75 are threadedly connected.

[0038] Specifically, one end of the adjusting screw 73 extending out of the mounting plate 4 is fixedly connected to a handle for facilitating the rotation of the adjusting screw 73. Before installing the device on the tank body, it is necessary to rotate the handle, and the handle drives the adjusting screw 73 to rotate, and the adjusting screw 73 drives the adjusting block 75 to move up and down, thereby adjusting the distance from the laser cutter 78 to the axis of the mounting plate 4, that is, adjusting the radius of the cut circle, and then installing the device on the tank body.

[0039] The present invention provides a laser cutting device for flash evaporation equipment production. Since the surface of the cylindrical tank body is a curved surface, as the mounting plate 4 rotates, the vertical distance between the cutting head of the laser cutter 78 and the surface of the tank body is always changing. When the laser cutter 78 is used for cutting, the cutting head of the laser cutter 78 needs to be at an appropriate distance from the surface of the object to be cut to facilitate the focusing of the laser cutter 78. The distance that fluctuates will affect the cutting accuracy of the laser cutter 78 and reduce the cutting quality. Therefore, in this embodiment, the adjustable cutting mechanism 7 also includes an adaptive adjustment structure. The adaptive adjustment structure can make the distance between the cutting head of the laser cutter 78 and the surface of the tank body at a fixed value, so that the distance between the laser cutter 78 and the surface of the tank body does not change with the position of the laser cutter 78, thereby keeping the cutting accuracy of the laser cutter 78 at an optimal state.

[0040] The adaptive adjustment structure includes a second servo motor 74 fixedly mounted on the side of the adjustment block 75, the output shaft of the second servo motor 74 is fixedly connected to a rotating plate 79, a plurality of guide rods 76 are slidably mounted on the rotating plate 79, a tension spring 77 is connected between the guide rods 76 and the rotating plate 79, and the ends of the plurality of guide rods 76 facing away from the second servo motor 74 are fixedly connected to the same mounting plate 710, the laser cutter 78 is fixedly mounted on the side of the mounting plate 710, and the side of the mounting plate 710 is also fixedly mounted with an abutment rod 72, the abutment rod 72 and the laser cutter 78 are located in the same vertical plane, the distance from the end of the abutment rod 72 to the surface of the mounting plate 710 is greater than the distance from the cutting head end of the laser cutter 78 to the surface of the mounting plate 710, the adaptive adjustment structure also includes an angle sensor 10, which is mounted between the sliding plate 2 and the rotating shaft 11, and the angle sensor 10 is used to detect the rotation angle of the rotating shaft 11.

[0041] Specifically, when the abutment rod 72 is pressed against the surface of the can body, a distance will be left between the cutting head of the laser cutter 78 and the surface of the can body. This distance is related to the focal position of the laser cutter 78 and can be set according to the model of the laser cutter 78 and the thickness of the can body material.

[0042] When in use, the adjusting screw 73 is in a vertical plane, and the sliding plate 2 and the mounting disk 4 are driven to move by the driving mechanism 9, and the mounting disk 4 drives the abutment rod 72 to abut against the tank body, and makes the tension spring 77 in a compressed state. At this time, the cutting head of the laser cutter 78 is at the top of the cut circle. Then, the laser cutter 78 and the first servo motor 3 are started. The first servo motor 3 drives the mounting disk 4 to rotate through the rotating shaft 11, and the mounting disk 4 drives the abutment rod 72 and the laser cutter 78 to move in a circular motion. At the same time, the angle sensor 10 detects the angle of rotation of the rotating shaft 11 and transmits the data to the controller. The controller controls the second servo motor 74 to rotate in the opposite direction, and its rotation angle is equal to the angle value of the rotation of the rotating shaft 11, so that the center plane of the abutment rod 72 and the laser cutter 78 can be in the same vertical plane.

[0043] Since the distances from points in the same vertical plane on the cylindrical tank body to the tank body axis are equal, no matter which position the mounting plate 4 drives the adjustable cutting mechanism 7 to rotate to, under the action of the tension spring 77, the abutment rod 72 abuts against the tank body, and the distance from the laser cutter 78 to the tank body surface is the distance from the laser cutter 78 to the end of the abutment rod 72, which is the focal length of the laser cutter 78. Therefore, the distance from the laser cutter 78 to the tank body surface remains unchanged, so that the laser cutter 78 is always at the optimal cutting distance, thereby avoiding a reduction in cutting quality.

[0044] The present invention provides a laser cutting device for flash evaporation equipment production. In this embodiment, the driving mechanism 9 includes a third servo motor 91 fixedly mounted on the base plate 1, and the output shaft of the third servo motor 91 is fixedly connected to a screw rod 92, and the screw rod 92 is threadedly connected to the sliding plate 2.

[0045] The present invention provides a laser cutting device for the production of flash evaporation equipment. In this embodiment, the fixing mechanism 6 includes a fixing seat 68 fixedly connected to the end of the base plate 1, and the fixing seat 68 is an arc-shaped block. Both ends of the fixing seat 68 are provided with a receiving groove 61. A slider 63 is slidably installed inside the receiving groove 61. A tension spring 62 is connected between the slider 63 and the receiving groove 61. A chain belt 64 is rotatably installed on the side of the slider 63, and a mounting block 66 is rotatably installed on the end of the chain belt 64. A side suction cup 65 is installed on the side of the mounting block 66. A vacuum pump 5 is fixedly installed on the base plate 1, and the side suction cup 65 is connected to the vacuum pump 5 through a first hose 67.

[0046] Specifically, the chain belt 64 is formed by a plurality of chain links that are rotatably mounted. The chain belt 64 can be deformed according to the curved surface of the tank body, and can be mounted on tank bodies of different diameters, and the mounting is more secure.

[0047] During installation, pull the chain belt 64 out of the storage slot 61 and stick the chain belt 64 to the surface of the tank body. Then press the side suction cup 65 on the tank body and start the vacuum pump 5. The vacuum pump 5 extracts the air in the side suction cup 65. Under the action of atmospheric pressure, the side suction cup 65 is adsorbed on the tank body.

[0048] When not in use, the chain belt 64 is retracted into the storage slot 61 under the tension of the tension spring 62, so as to facilitate the storage of the device.

[0049] The present invention provides a laser cutting device for flash evaporation equipment production. Since the chain belt 64 is relatively soft, the chain belt 64 may vibrate during the cutting process, thereby causing the laser cutter 78 to have cutting deviations and reduce the cutting quality. Therefore, in this embodiment, the fixing mechanism 6 further includes two lower supporting mechanisms 69, and the two lower supporting mechanisms 69 are both mounted on the bottom of the fixing base 68;

[0050] The lower support mechanism 69 includes a ball groove 692 fixedly mounted on the bottom of the fixed seat 68, a spherical joint 693 is rotatably mounted in the ball groove 692, a connecting rod 694 is fixedly connected to the side of the spherical joint 693, a rotating joint 696 is rotatably mounted on one end of the connecting rod 694, a vertical plate 697 is fixedly connected to the bottom of the rotating joint 696, a movable block 699 is slidably mounted on the vertical plate 697, a lower suction cup 698 is mounted on the side of the movable block 699 close to the tank body, a reset spring 6910 is connected between the movable block 699 and the vertical plate 697, and the lower suction cup 698 is connected to the vacuum pump 5 through a second hose 695.

[0051] Specifically, the spherical joint 693 can rotate arbitrarily inside the ball groove 692, so that it can be adaptively adjusted for cans of different diameters. After adjusting the angle of the connecting rod 694, the vertical plate 697 is rotated to make the lower suction cup 698 tangent to the surface of the can, and then the movable block 699 is pushed to make the lower suction cup 698 stick to the surface of the can, and the vacuum pump 5 is started. The vacuum pump 5 extracts the air in the lower suction cup 698. Under the action of atmospheric pressure, the lower suction cup 698 is adsorbed on the can, and the two connecting rods 694 support the bottom of the fixing base 68, so that the fixing base 68 is installed more stably, avoiding the shaking of the fixing base 68, and improving the cutting quality.

[0052] A notch 691 matching the diameter of the connecting rod 694 is provided on the side of the ball groove 692 so that the connecting rod 694 can be rotated to the side of the ball groove 692 for easy storage.

[0053] The present invention provides a laser cutting device for flash evaporation equipment production. Since the tank body is in a three-dimensional state, after cutting, the cut material may fall into the tank body or may get stuck in the cutting opening, making it inconvenient to remove. Therefore, in this embodiment, a grabbing mechanism 8 is further installed on the side of the mounting plate 4. The grabbing mechanism 8 includes a grabbing rod 83 fixedly installed on the side of the mounting plate 4. The axis of the grabbing rod 83 coincides with the axis of the rotating shaft 11. The end of the grabbing rod 83 is rotatably installed with a rotary joint 82. The rotary joint 82 is fixedly installed on the side of the mounting plate 4. A grabbing suction cup 81 is installed at the end of the adapter 82, and an exhaust cavity connected to the grabbing suction cup 81 is opened inside the grabbing rod 83. One end of the exhaust cavity passes through the mounting plate 4 and extends to the inside of the rotating shaft 11. A plurality of exhaust holes 86 connected to the exhaust cavity are opened on the side of the rotating shaft 11. A wind collecting hood 84 is also rotatably installed on the rotating shaft 11. The wind collecting hood 84 is connected to the exhaust holes 86. The wind collecting hood 84 is fixedly installed on the sliding plate 2 and is connected to the vacuum pump 5 through a third hose 85.

[0054] Specifically, after the fixing mechanism 6 is installed, the driving mechanism 9 drives the sliding plate 2 to approach the tank body, and the sliding plate 2 drives the mounting plate 4 and the grabbing rod 83 to move. When the abutting rod 72 abuts against the tank body and the tension spring 77 is in a compressed state, the grabbing suction cup 81 is attached to the surface of the tank body, and the vacuum pump 5 is started, and the grabbing suction cup 81 is adsorbed on the tank body.

[0055] After the laser cutter 78 completes cutting around the grabbing rod 83, the cut material is adsorbed by the grabbing suction cup 81 and will not fall into the tank body. Then the driving mechanism 9 drives the sliding plate 2 to retreat, and the sliding plate 2 drives the grabbing rod 83 and the grabbing suction cup 81 to retreat. The grabbing suction cup 81 takes the material out of the cutting mouth, making it more convenient to take the material.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0057] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
