[0001] This utility model relates to the field of machine tool equipment technology, and in particular to a laser cutting machine material rack assembly. Background Technology

[0002] Chinese patent number "CN102218612B" discloses a material rack assembly for a laser cutting machine. The assembly features a transmission hook on the front end of the frame and a fixing hook on the rear end. Positioning plates are located on a pair of adjacent sides of the frame, with adjusting bolts threaded onto the top of the positioning plates. Support plates are inserted into slots on the inner side of the frame, and rollers are installed on the two outer sides of the frame. The assembly is structurally stable and reasonable, easy to operate, cost-effective, and effectively improves the cutting accuracy of the workpiece and the efficiency of the equipment.

[0003] This device can be used for the production of material racks. The material racks can be exchanged through the cooperation of transmission hooks and rollers, which improves the efficiency of use. However, during long-term use, various wastes will be adsorbed on the grid teeth, which are difficult to clean and can also easily be adsorbed on the processed products, affecting the cutting effect. Therefore, an improvement was proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where various waste materials accumulate on the grid teeth during long-term use, making them difficult to clean and easily adhering to the processed products, thus affecting the cutting effect. Therefore, this invention proposes a material rack assembly for a laser cutting machine.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A material rack assembly for a laser cutting machine is designed, including a material rack frame. The upper surface of the material rack frame has multiple sets of symmetrical locking slots. A grid assembly is movably inserted into the two sets of symmetrical locking slots. Support blocks are fixedly connected to the four corners of the material rack frame. The support blocks have slots inside, and plug rods are movably inserted into the slots. A chip removal plate is provided above the material rack frame. The plug rods are fixedly connected to the lower surface of the chip removal plate. The chip removal plate has a number of toothed grooves equal to the number of locking slots inside. The grid assembly is movably inserted into the toothed grooves.

[0007] Preferably, the grid assembly includes a support bar, the upper end face of which is fixedly connected to multiple sets of grid teeth, the height of the support bar is equal to the depth of the locking groove, and the grid teeth protrude completely from the upper end face of the material rack frame.

[0008] Preferably, the material rack frame has multiple sets of fixing rods that are movably inserted inside, and the fixing rods pass through and fix the multiple sets of support bars.

[0009] Preferably, both ends of the fixing rod are provided with anti-detachment rings, and the anti-detachment rings are threadedly connected to the fixing rod.

[0010] Preferably, both ends of the support bar are fixedly connected to limit blocks, and the inner end face of the limit block movably abuts against the outer end face of the material rack frame.

[0011] Preferably, mounting brackets are fixedly connected to the four corners of the lower end face of the material rack frame, and electric push rods are fixedly installed inside the mounting brackets. The output end of the electric push rods is connected to the plug rods in a transmission manner.

[0012] Preferably, a fixing plate is fixedly connected to both the left and right sides of the material rack frame. The fixing plate is movably engaged with the guide rail of the laser cutting device, and the fixing plate and the guide rail are fixedly connected by bolts.

[0013] The present invention provides a material rack assembly for a laser cutting machine, which has the following advantages: the chip removal plate can be fixed by the cooperation of the slot and the plug rod. After the cutting is completed, the plug rod is moved by the electric push rod, which drives the chip removal plate to move upward. At this time, under the action of the tooth groove, most of the waste chips on the front and back sides of the grid teeth are scraped off by the chip removal plate. At the same time, the remaining part becomes easy to clean because it lacks adsorption points and can be removed by the long scraper, thereby reducing the impact of waste chips on cutting and improving the cutting effect of the device.

[0014] The grid assembly is engaged by the locking slot and the limiting block. Then, the grid assembly is fixed by inserting a fixing rod, which prevents the grid assembly from moving or detaching from the material rack frame. After the fixing rod is removed, the grid assembly can be easily replaced or its number increased or decreased according to different processing needs, further facilitating the use of the material rack. At the same time, when the device needs to process softer materials (such as cloth), the chip removal plate can be raised and the material can be placed on the chip removal plate for processing, preventing the material from getting stuck in the gaps between the grid assemblies, thereby increasing the efficiency of the device.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 A material rack assembly for a laser cutting machine includes a material rack frame 1. The upper surface of the material rack frame 1 has multiple symmetrically arranged slots 102. A grid assembly is movably inserted into each of the two symmetrical slots 102. Support blocks 103 are fixedly connected to each of the four corners of the material rack frame 1. Slots 104 are formed inside each support block 103, and insertion rods 202 are movably inserted into each slot 104. A chip removal plate 2 is arranged above the material rack frame 1, and the insertion rods 202 are fixedly connected to the lower surface of the chip removal plate 2 for chip removal. The plate 2 has a number of toothed grooves 201 equal to the number of slots 102 inside. The grid assembly is movably inserted into the inside of the toothed grooves 201. The chip removal plate 2 can be fixed by the cooperation of the slot 104 and the insertion rod 202. After cutting, most of the waste chips on the front and rear sides of the grid assembly are scraped off by the chip removal plate 2 as the chip removal plate 2 moves. At the same time, the remaining part becomes easy to clean because it lacks adsorption points and can be removed by the long scraper. This reduces the impact of waste chips on cutting and improves the cutting effect of the device.

[0023] refer to Figure 1-4 To facilitate the driving of the chip removal plate 2, mounting brackets 101 are fixedly connected at the four corners of the lower end face of the material rack frame 1. An electric push rod 5 is fixedly installed inside the mounting bracket 101. The output end of the electric push rod 5 is connected to the plug rod 202 for transmission. At this time, the plug rod 202 can be driven to rise and fall by the electric push rod 5, thereby driving the chip removal plate 2 to move.

[0024] refer to Figure 1To facilitate the fixing of the material rack frame, fixing plates 6 are fixedly connected to both the left and right sides of the material rack frame 1. The fixing plates 6 are movably engaged with the guide rail of the laser cutting device. The fixing plates 6 and the guide rail are fixedly connected by bolts. At this time, the installation of the device is completed, and disassembly and installation are convenient.

[0025] refer to Figure 4 , 5 To facilitate the fixing of the grid assembly, the grid assembly includes a support bar 3. Multiple sets of grid teeth 301 are fixedly connected to the upper end face of the support bar 3. The height of the support bar 3 is equal to the depth of the locking groove 102. The grid teeth 301 protrude completely from the upper end face of the material rack frame 1. After fixing, the grid teeth 301 protrude completely from the material rack frame 1, which facilitates the loading and unloading of materials by the device.

[0026] refer to Figure 4 In order to fix the grid assembly and prevent it from moving or falling off, multiple sets of fixing rods 4 are movably inserted inside the material rack frame 1. The fixing rods 4 pass through and fix multiple sets of support bars 3, so that the grid assembly can be easily replaced when the fixing rods 4 are pulled out.

[0027] refer to Figure 5 To facilitate the insertion of the fixing rod 4, the left and right ends of the support bar 3 are fixedly connected to the limiting block 302. The inner end face of the limiting block 302 moves against the outer end face of the material rack frame 1. When the grid assembly is inserted into the slot 102, it cannot move left or right, thus facilitating the insertion of the fixing rod 4.

[0028] refer to Figure 4 To prevent the fixing rod from detaching, anti-detachment rings 401 are provided at both ends of the fixing rod 4. The anti-detachment rings 401 are threadedly connected to the fixing rod 4. After rotating off the anti-detachment rings 401, the fixing rod 4 can be pulled out.

[0029] Working method: During operation, the fixing plate 6 is inserted into the guide rail and then fixed with bolts. The grid assembly is engaged by the cooperation of the locking groove 102 and the limiting block 302. Then, the fixing rod 4 is inserted into the grid assembly, which prevents the grid assembly from moving and detaching from the material rack frame 1. After the fixing rod 4 is removed, the grid assembly can be easily replaced or its quantity increased or decreased according to different processing requirements, further facilitating the use of the material rack. The chip removal plate 2 can be fixed by the cooperation of the slot 104 and the plug-in rod 202. After cutting is completed, the plug-in rod is pushed by the electric push rod 5. Move 202, causing the chip removal plate 2 to move upward. At this time, under the action of the tooth groove 201, most of the waste chips on the front and rear sides of the grid teeth 301 are scraped off by the chip removal plate 2. Meanwhile, the remaining part becomes easier to clean because it lacks adsorption points and can be removed by the long scraper, thereby reducing the impact of waste chips on cutting and improving the cutting effect. At the same time, when the device needs to process relatively soft materials (such as cloth), by raising the chip removal plate 2, the material can be placed on the chip removal plate 2 for processing, avoiding the material from getting stuck in the gap between the grid components, further increasing the effectiveness of the device.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
