[0001] This utility model relates to the field of refrigerator manufacturing technology, and in particular to a laser cutting device for cutting refrigerator unit panels. Background Technology

[0002] In the refrigerator manufacturing industry, core functional components include refrigeration system parts such as compressors, condensers, evaporators, and capillary tubes, as well as structural components such as control boards and brackets. The processing of these components often requires cutting and punching raw materials into blanks or prototype parts that meet dimensional requirements. This manufacturing term is called blanking, a crucial pre-processing step for subsequent steps. In the blanking of refrigerator unit panels, laser cutting equipment has become a commonly used tool due to its high precision and flexibility.

[0003] However, existing laser cutting equipment that uses adsorption to fix refrigerator unit panels has certain limitations. Such equipment typically lacks components for cleaning the bottom of the panel and the bottom of the cutting groove. During actual processing, the bottom of the panel may carry dust and other impurities, and metal shavings and dust generated during cutting may accumulate in the cutting groove. These impurities easily reduce the negative pressure adsorption effect, making the panel unstable and affecting cutting accuracy and quality. Therefore, to solve the above-mentioned problems in the existing technology and improve the processing effect of laser cutting equipment on refrigerator unit panels, a laser cutting device for refrigerator unit panel blanking is proposed. Utility Model Content

[0006] A laser cutting device for refrigerator unit sheet blanking includes a cutting frame with a cutting groove. A negative pressure pump is located at the bottom of the cutting frame. The bottom wall of the cutting groove has suction holes that cooperate with the negative pressure pump. Multiple conveying rollers and a cleaning roller are mounted on the cutting frame. A drive motor connected to one of the conveying rollers is located on the cutting frame. Adjacent conveying rollers are connected via a synchronization mechanism. A rotating groove and a transmission groove are located on the outer wall of the cutting frame. A screw is rotatably mounted in the rotating groove. The ends of the screw and the conveying rollers both extend into the transmission groove and are connected via a linkage mechanism. The cleaning roller is connected to the nearest conveying roller via a transmission mechanism. A movable frame is threaded onto the screw. A dust suction hood is mounted on the movable frame via a dust suction pump.

[0007] Preferably, the synchronization mechanism includes a timing pulley mounted on the conveyor roller, and two adjacent timing pulleys are connected by a timing belt.

[0008] Preferably, the linkage mechanism includes a synchronous gear mounted on the cleaning roller, and the screw is provided with a linkage gear that meshes with the synchronous gear.

[0011] Preferably, a limiting rod is provided in the rotating groove, and the limiting rod is parallel to the screw and slides through the screw.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up conveyor rollers, cleaning rollers and dust pumps, flexible conveying of the sheet material is achieved, and the bottom wall of the sheet material and the bottom wall of the cutting groove are cleaned, so as to avoid dust and impurities affecting the stability of the sheet material when it is subsequently adsorbed.

[0014] 2.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A laser cutting device for cutting refrigerator unit panels includes a cutting frame 1, a cutting groove 2 on the cutting frame 1, and an L-shaped part on the cutting frame 1. A laser cutting component is installed on the cutting frame 1 using a mature existing moving component, which can realize laser cutting processing of the panel in the cutting groove 2. The specific moving component and laser cutting component are both mature existing products, so they will not be described in detail in this solution.

[0022] The bottom of the cutting frame 1 is equipped with a negative pressure pump 14, and the bottom wall of the cutting groove 2 is equipped with an adsorption hole 3 that cooperates with the negative pressure pump 14. Multiple conveying rollers 12 and cleaning rollers 13 are installed on the cutting frame 1. The cutting frame 1 is equipped with a drive motor 15 connected to one of the conveying rollers 12. Two adjacent conveying rollers 12 are connected by a synchronization mechanism. The outer wall of the cutting frame 1 is equipped with a rotating groove 4 and a transmission groove 16. A screw 5 is rotatably installed in the rotating groove 4. The ends of the screw 5 and the conveying roller 12 both extend into the transmission groove 16 and are connected by a linkage mechanism. The cleaning roller 13 is connected to the nearest conveying roller 12 by a transmission mechanism. A movable frame 6 is threaded on the screw 5. A dust suction hood is provided on the movable frame 6 through a dust suction pump 7.

[0023] The synchronization mechanism includes synchronous pulleys 8 mounted on the conveyor rollers 12, and adjacent synchronous pulleys 8 are connected by synchronous belts 9. As shown in the figure, the synchronous rotation of multiple conveyor rollers 12 is achieved by the above components.

[0024] The linkage mechanism includes a synchronizing gear 18 mounted on the cleaning roller 13, and a linkage gear 17 meshing with the synchronizing gear 18 on the screw 5. As shown in the figure, the synchronous rotation of the cleaning roller 13 and the screw 5 is achieved by the aforementioned gear assembly.

[0025] The transmission mechanism includes a drive gear 10 mounted on the conveyor roller 12, and a transmission gear 11 on the cleaning roller 13 that meshes with the drive gear 10. As shown in the figure, the synchronous rotation of the cleaning roller 13 and the conveyor roller 12 is achieved by the aforementioned gear assembly.

[0026] Both the driving gear 10 and the transmission gear 11 are spur gears, while both the synchronizing gear 18 and the linkage gear 17 are bevel gears. A limiting rod 19 is provided within the rotating groove 4, parallel to and slidingly passing through the screw 5. This limiting rod 19 effectively limits the movement of the movable frame 6, preventing it from rotating along with the screw 5.

[0027] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods for each component all employ mature methods from the prior art, and will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0028] In use, the sheet material is placed on multiple conveyor rollers 12. The drive motor 15 is started, and the multiple conveyor rollers 12 rotate under the action of the synchronous pulley 8 and the synchronous belt 9, conveying the sheet material into the cutting groove 2. During this process, the drive gear 10, in combination with the transmission gear 11, enables the cleaning roller 13 to rotate. The cleaning roller 13 rotates in the opposite direction to the conveyor roller 12, which enables the cleaning operation of the bottom of the sheet material. During this process, the synchronous gear 18, in combination with the linkage gear 17, enables the rotation of the screw 5. The moving frame 6 can drive the dust pump 7 and other components to move from a position close to the cleaning roller 13 to a position away from the cleaning roller 13. During this process, the dust pump 7 can perform the dust suction cleaning operation of the cutting groove 2.

[0029] Finally, the sheet material is placed in the cutting groove 2. At this time, the negative pressure pump 14 is started and used with the adsorption hole 3 to achieve negative pressure adsorption of the sheet material. Finally, the moving component on the cutting frame 1 and the laser cutting component are used to perform laser cutting.
