Description

Technical Field

[0001] This utility model belongs to the field of mechanical automation technology, and in particular relates to a feeding device for a laser cutting machine. Background Technology

[0002] The feeding device of a laser cutting machine is used to automatically feed the material to be cut into the worktable of the laser cutting machine. Its main function is to ensure that the material can be delivered accurately and stably to the working area of ​​the laser cutting machine so that subsequent laser cutting operations can be carried out. The design of the feeding device directly affects the cutting quality, efficiency and stability of the entire cutting process.

[0003] Before a laser cutting machine can cut a material, the surface of the material usually needs to be cleaned. However, if the cleaning is not thorough enough, stains will remain on the surface of the material, which will affect the transmission of the laser beam and the focusing of the focal point, resulting in an uneven cut surface. Therefore, we propose a feeding device for a laser cutting machine. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for a laser cutting machine. By squeezing the cleaning strip with the material, the cleaning strip causes the connecting plate to move upward. The movement of the connecting plate then squeezes the spring, thus solving the problem of thoroughly cleaning the material surface before cutting.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a feeding device for a laser cutting machine, including a support frame, a support plate fixedly connected to the top of the support frame, a connecting shell fixedly connected to the outer surface of the support plate, a cleaning mechanism provided on the outer surface of the connecting shell, and a fixing mechanism provided on the top of the support plate.

[0007] The cleaning mechanism includes a motor frame, a motor fixedly connected to the inner wall of the motor frame, a threaded rod fixedly connected to the output shaft of the motor via a coupling, a moving block threadedly connected to the outer surface of the threaded rod, a limit block fixedly connected to the outer surface of the support plate, a limit rod fixedly connected to the inner wall of the limit block, a laser cutter fixedly connected to the inner wall of the connecting shell, a connecting frame fixedly connected to the outer surface of the connecting shell, a fixed shell fixedly connected to the top of the connecting frame, a telescopic cylinder fixedly connected to the inner wall of the fixed shell, a connecting plate fixedly connected to the bottom of the telescopic cylinder, and a spring fixedly connected to the inner wall of the fixed shell. Through the connecting plate, which can slide within the fixed shell, the cleaning strip can be made to adhere tightly to the material surface for cleaning, ensuring the effectiveness of laser cutting and resulting in a smooth and clean cutting edge.

[0008] Furthermore, a cleaning strip is fixedly connected to the inner wall of the connecting plate, the outer surface of the motor frame is fixedly connected to the outer surface of the support frame, two moving blocks are provided, and several limiting blocks are provided. The inner wall of one limiting block is rotatably connected to the outer surface of the threaded rod.

[0009] Furthermore, the outer surface of the limiting rod is slidably connected to the inner wall of the moving block, a total of several telescopic cylinders are provided, a total of several springs are provided, the side of the spring away from the inner wall of the fixed shell is fixedly connected to the outer surface of the connecting plate, and the inner side of the spring is sleeved with the outer surface of the telescopic cylinder.

[0010] Furthermore, the fixing mechanism includes a sliding groove 1 formed inside the support plate. There are two sliding grooves in total. The inner wall of the sliding groove 1 is slidably connected to the outer surface of the moving block. A moving platform is fixedly connected to the top of the moving block. The bottom of the moving platform is slidably connected to the top of the support plate.

[0011] Furthermore, the moving table has two sliding grooves inside. A slider is slidably connected to the inner wall of the sliding groove, and several sliders are provided. A clamping strip is fixedly connected to the top of the slider. The clamping strip, which can slide on the moving table, can fix the material during feeding, prevent the material from moving during the cutting process, reduce cutting errors and inconsistencies caused by material displacement, and thus ensure the accuracy of the cutting path.

[0012] Furthermore, a threaded block is fixedly connected to the outer surface of the clamping bar, a bidirectional threaded rod is threadedly connected to the inner wall of the threaded block, and a knob is fixedly connected to the outer surface of the bidirectional threaded rod.

[0013] Furthermore, a second limiting block is rotatably connected to the outer surface of the bidirectional threaded rod, and a plurality of the second limiting blocks are provided. The outer surface of the second limiting block is fixedly connected to the outer surface of the moving platform.

[0014] Furthermore, a second limiting rod is fixedly connected to the inner wall of the second limiting block, and a sliding block is fixedly connected to the side of the clamping bar away from the threaded block. The inner wall of the sliding block is slidably connected to the outer surface of the second limiting rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a connecting plate. When material comes into contact with the cleaning strip, the cleaning strip cleans the stains on the material surface. At this time, the material pushes the cleaning strip upward, causing the cleaning strip to move the connecting plate upward. The connecting plate then compresses the spring, and the spring's rebound causes the cleaning strip to adhere tightly to the material surface for cleaning. By using a connecting plate that can slide within the fixed housing, the cleaning strip can be kept in close contact with the material surface for cleaning, ensuring the effectiveness of laser cutting and resulting in a smooth and clean cutting edge.

[0017] 2. This utility model incorporates a clamping bar. When the knob is rotated, it drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod causes the threaded blocks to move closer to each other on the rod. Subsequently, the threaded blocks drive the clamping bar to move on the moving table. Simultaneously, the clamping bar drives the slider to slide within the second slide groove. By using the clamping bar that can slide on the moving table, the material can be fixed during feeding, preventing it from moving during the cutting process. This reduces cutting errors and inconsistencies caused by material displacement, thereby ensuring the accuracy of the cutting path.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 As shown, this utility model is a feeding device for a laser cutting machine, including a support frame 101, a support plate 103 fixedly connected to the top of the support frame 101, a connecting shell 102 fixedly connected to the outer surface of the support plate 103, a cleaning mechanism 2 provided on the outer surface of the connecting shell 102, and a fixing mechanism 3 provided on the top of the support plate 103. The fixing mechanism 3 clamps and fixes the material to be cut, and then the material slides into the connecting shell 102 on the support plate 103 and is cut. During the sliding process, the device cleans the material.

[0030] Cleaning mechanism 2 includes a motor frame 201, with a motor 202 fixedly connected to the inner wall of the motor frame 201. A threaded rod 203 is fixedly connected to the output shaft of the motor 202 via a coupling. A moving block 213 is threadedly connected to the outer surface of the threaded rod 203. The motor frame 201 fixes the position of the motor 202 to prevent the motor 202 from rotating during operation, thus affecting the normal operation of the device. A limit block 204 is fixedly connected to the outer surface of the support plate 103, and a limit rod 205 is fixedly connected to the inner wall of the limit block 204. A laser cutter 206 is fixedly connected to the inner wall of the connecting shell 102. A connecting frame 207 is fixedly connected. The moving block 213 can slide on the limiting rod 205. At this time, the limiting rod 205 restricts the moving block 213 to prevent it from rotating vertically due to the rotation of the threaded rod 203, thus affecting the feeding process. A fixed shell 208 is fixedly connected to the top of the connecting frame 207. A telescopic cylinder 209 is fixedly connected to the inner wall of the fixed shell 208. A connecting plate 211 is fixedly connected to the bottom of the telescopic cylinder 209. A spring 210 is fixedly connected to the inner wall of the fixed shell 208. When the connecting plate 211 moves upward, it will compress the spring 210, causing the spring to... 210 has the ability to spring back, thereby pushing the connecting plate 211. A cleaning strip 212 is fixedly connected to the inner wall of the connecting plate 211. The outer surface of the motor frame 201 is fixedly connected to the outer surface of the support frame 101. Two moving blocks 213 are provided, and several limit blocks 204 are provided. When the connecting plate 211 is pushed by the spring 210, the cleaning strip 212 will be tightly pressed against the material surface, thus making the cleaning of the material more thorough. The inner wall of the limit block 204 is rotatably connected to the outer surface of the threaded rod 203, and the outer surface of the limit rod 205 is slidably connected to the inner wall of the moving block 213. The telescopic cylinder 209 is provided with... Several limit blocks 204 restrict the position of the threaded rod 203, so that the threaded rod 203 can only rotate in a fixed position, preventing the threaded rod 203 from detaching from the device and thus affecting the operation of the device. Several springs 210 are provided. The side of the spring 210 away from the inner wall of the fixed shell 208 is fixedly connected to the outer surface of the connecting plate 211. The inner side of the spring 210 is sleeved with the outer surface of the telescopic cylinder 209. The telescopic cylinder 209 restricts the movement trajectory of the spring 210, preventing the spring 210 from tilting during compression or rebound, which helps the cleaning strip 212 to adhere to the material surface for cleaning.

[0031] The fixing mechanism 3 includes two slide grooves 301 formed inside the support plate 103. The inner wall of the slide groove 301 is slidably connected to the outer surface of the moving block 213. A movable platform 302 is fixedly connected to the top of the moving block 213. The slide groove 301 restricts the movement of the moving block 213, ensuring that the moving block 213 can only move on a specific track and preventing the moving block 213 from detaching from the device. The bottom of the movable platform 302 is slidably connected to the top of the support plate 103. Two slide grooves 303 are formed inside the movable platform 302. A slider 304 is slidably connected to the inner wall of the slide groove 303. The movable platform 302 can slide on the support plate 103, facilitating the movement of the moving block 213. The material is fed into the connecting shell 102 for cutting. Then, the slider 304, which can slide in the slide groove 303, facilitates subsequent transmission. Several sliders 304 are provided. A clamping bar 305 is fixedly connected to the top of the slider 304. A threaded block 306 is fixedly connected to the outer surface of the clamping bar 305. A bidirectional threaded rod 307 is threadedly connected to the inner wall of the threaded block 306. A knob 308 is fixedly connected to the outer surface of the bidirectional threaded rod 307. The slider 304 restricts the movement of the clamping bar 305 so that the clamping bar 305 will not detach from the moving table 302 during movement. Then, the bidirectional threaded rod 307 can be rotated by the knob 308, thereby causing the bidirectional threaded rod 307 to drive the clamping bar 305 to move.

[0032] A limiting block 309 is rotatably connected to the outer surface of the bidirectional threaded rod 307. Several limiting blocks 309 are provided. The outer surface of the limiting block 309 is fixedly connected to the outer surface of the moving table 302. The limiting block 309 restricts the position of the bidirectional threaded rod 307 to prevent it from disengaging from the device due to rotation, thereby affecting the normal operation of the device. A limiting rod 310 is fixedly connected to the inner wall of the limiting block 309. A sliding block 311 is fixedly connected to the side of the clamping bar 305 away from the threaded block 306. The inner wall of the sliding block 311 is slidably connected to the outer surface of the limiting rod 310. The sliding block 311, which can slide on the limiting rod 310, restricts the position of the clamping bar 305, so that the clamping bar 305 will not rotate in the vertical direction, thereby ensuring that the clamping bar 305 can clamp the material.

[0033] One specific application of this embodiment is:

[0034] When the operator needs to use the equipment, first place the material to be cut on the moving table 302, and then turn the knob 308. At this time, the knob 308 will drive the bidirectional threaded rod 307 to rotate. Then, the rotation of the bidirectional threaded rod 307 will cause the threaded blocks 306 to move closer to each other on the bidirectional threaded rod 307. After that, the threaded blocks 306 will drive the clamping strip 305 to move on the moving table 302. At the same time, the clamping strip 305 will drive the slider 304 to slide in the second slide groove 303. At this time, the clamping strip 305 will also drive the sliding block 311 to slide on the second limit rod 310, thereby clamping the material with the clamping strip 305. This achieves the goal of fixing the material during feeding, preventing the material from moving during the cutting process, reducing cutting errors and inconsistencies caused by material displacement, and thus ensuring the accuracy of the cutting path. The process involves starting the motor 202, which rotates the threaded rod 203. This rotation causes the moving block 213 to move along the threaded rod 203 toward the connecting shell 102, thus moving the moving block 213 and the moving table 302. When the material comes into contact with the cleaning strip 212, the cleaning strip 212 cleans the dirt on the material surface. The material pushes the cleaning strip 212 upward, causing the cleaning strip 212 to move the connecting plate 211 upward. The connecting plate 211 then compresses the spring 210, and the spring 210's rebound causes the cleaning strip 212 to adhere tightly to the material surface for cleaning. This ensures the effectiveness of laser cutting, resulting in a smooth and clean cutting edge.
