It solves the problem that after the perforated conveyor belt collects molten material, a large amount of residue remains. In order to ensure the normal operation of the equipment and processing accuracy, regular cleaning and maintenance are required. However, this equipment is not equipped with an auxiliary cleaning structure and can only rely on manual cleaning, which consumes a lot of manpower.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser cutting machine for producing fire door frames, comprising a machine body, a conveyor belt, an XY-axis moving module, and a laser head. The conveyor belt is fixedly installed on the top of the machine body, the XY-axis moving module is fixedly installed on the top of the machine body, the laser head is disposed on the surface of the XY-axis moving module, a cleaning pipe is disposed on the left side of the top of the conveyor belt, a high-pressure nozzle is connected to the bottom of the surface of the cleaning pipe, multiple high-pressure nozzles are disposed and distributed at equal intervals, a reciprocating mechanism is fixedly installed on the front side of the surface of the cleaning pipe, and a water supply assembly is connected to the rear end of the cleaning pipe.

[0007] In a preferred embodiment of this invention, the reciprocating mechanism includes a moving block, which is fixedly installed on the front side of the cleaning pipe surface.

The drive motor is fixedly installed on the right side of the machine body, and the output end of the drive motor is fixedly connected to the right side of the lead screw.

[0008] As a preferred embodiment of this utility model, the water supply component includes a connecting pipe, which is connected to the rear end of the cleaning pipe, and the other end of the connecting pipe is connected to a water pump, the input end of the water pump being connected to a water tank.

[0009] In a preferred embodiment of this invention, the water tank is located at the bottom of the body, and the body is a through-type structure.

[0010] As a preferred embodiment of this utility model, a filter plate is fixedly installed on the top of the inside of the water tank, and a locking block is fixedly connected to the left and right sides of the filter plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model features a cleaning pipe equipped with a high-pressure nozzle, a reciprocating mechanism, and a water supply component installed at the top of the conveyor belt. The water supply component supplies water to the cleaning pipe, and the reciprocating mechanism drives the cleaning pipe to move at the top of the conveyor belt. As it moves, water is sprayed onto the conveyor belt through the high-pressure nozzle, thus completing the cleaning work of the conveyor belt. This improves cleaning efficiency and solves the problem that after collecting molten material, the perforated conveyor belt will have a large amount of residue left behind.

[0015] 2. This utility model, by setting up a reciprocating mechanism, allows the drive motor to be started when the conveyor belt needs to be cleaned. The output end of the drive motor drives the lead screw to rotate. Since the bottom of the moving block is threadedly connected to the lead screw, the moving block will move linearly along the axial direction of the lead screw under the action of thread transmission. This, in turn, drives the cleaning pipe fixed on the moving block to reciprocate. During the reciprocating motion of the cleaning pipe, the high-pressure nozzles at the bottom of its surface continuously spray high-pressure water jets onto the conveyor belt, washing away the residue attached to the surface of the conveyor belt. Compared with manual cleaning, the degree of automation is greatly improved, and the labor intensity is reduced.

[0016] 3. This utility model provides a stable water supply to the cleaning pipe by setting up a water supply component, which includes a water tank, a water pump, and a connecting pipe. This ensures that the high-pressure nozzle can continuously spray high-pressure water, guaranteeing the cleaning effect on the conveyor belt. Moreover, the water supply component has a simple structure, is easy to install and maintain, effectively reducing equipment maintenance costs while ensuring efficient cleaning work.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3As shown, the present invention provides a laser cutting machine for producing fire door frames, comprising a machine body 1, a conveyor belt 2, an XY axis moving module 3, and a laser head 4. The conveyor belt 2 is fixedly installed on the top inside the machine body 1, the XY axis moving module 3 is fixedly installed on the top of the machine body 1, the laser head 4 is disposed on the surface of the XY axis moving module 3, a cleaning pipe 5 is disposed on the left side of the top of the conveyor belt 2, a high-pressure nozzle 6 is connected to the bottom of the surface of the cleaning pipe 5, multiple high-pressure nozzles 6 are disposed and distributed at equal intervals, a reciprocating mechanism 7 is fixedly installed on the front side of the surface of the cleaning pipe 5, and a water supply component 8 is connected to the rear end of the cleaning pipe 5.

[0023] refer to Figure 1 , Figure 2 and Figure 3 The reciprocating mechanism 7 includes a moving block 71, which is fixedly installed on the front side of the surface of the cleaning pipe 5. A lead screw 72 is threadedly connected to the bottom of the moving block 71. A drive motor 73 is provided on the right side of the lead screw 72. The drive motor 73 is fixedly installed on the right side of the machine body 1. The output end of the drive motor 73 is fixedly connected to the right side of the lead screw 72.

[0024] As a technical optimization of this utility model, by setting a reciprocating mechanism 7, when the conveyor belt 2 needs to be cleaned, the drive motor 73 is started. The output end of the drive motor 73 drives the lead screw 72 to rotate. Since the bottom of the moving block 71 is threadedly connected to the lead screw 72, under the action of thread transmission, the moving block 71 will move linearly along the axial direction of the lead screw 72, thereby driving the cleaning pipe 5 fixed on the moving block 71 to reciprocate. During the reciprocating motion, the high-pressure nozzle 6 at the bottom of the cleaning pipe 5 continuously sprays high-pressure water jets onto the conveyor belt 2 to wash away the residue attached to the surface of the conveyor belt 2. Compared with manual cleaning, the degree of automation is greatly improved and the labor intensity is reduced.

[0025] refer to Figure 1 , Figure 2 and Figure 3 The water supply component 8 includes a connecting pipe 81, which is connected to the rear end of the cleaning pipe 5. The other end of the connecting pipe 81 is connected to a water pump 82, and the input end of the water pump 82 is connected to a water tank 83.

[0026] As a technical optimization of this utility model, by setting up a water supply component 8, the water tank 83, water pump 82 and connecting pipe 81 in the water supply component 8 provide a stable water supply to the cleaning pipe 5, ensuring that the high-pressure nozzle 6 can continuously spray high-pressure water flow, ensuring the cleaning effect on the conveyor belt 2. Moreover, the water supply component 8 has a simple structure, is easy to install and maintain, can effectively reduce equipment maintenance costs, and at the same time ensure the efficient progress of the cleaning work.

[0027] refer to Figure 1 , Figure 2 and Figure 3 The water tank 83 is located at the bottom inside the body 1, which is a through-type structure.

[0028] As a technical optimization of this utility model, the internal space structure of the equipment is optimized by the through-hole design of the body 1 and the position layout of the water tank 83, making the conveyor belt 2 transport and cleaning work smoother. At the same time, sewage and residue can fall directly into the water tank 83 for centralized treatment, avoiding their accumulation inside the equipment. This not only keeps the inside of the equipment clean, but also facilitates the unified treatment of sewage and residue in the future, improving the practicality and environmental friendliness of the equipment.

[0029] refer to Figure 1 , Figure 2 and Figure 3 A filter plate 9 is fixedly installed on the top inside the water tank 83. The left and right sides of the filter plate 9 are fixedly connected with clips 10. The inner wall of the water tank 83 is provided with a slot 11 for use with the filter plate 9.

[0030] As a technical optimization of this utility model, the filter plate 9 effectively separates the residue in the sewage, preventing the residue from accumulating in the water tank 83 and clogging the water pump 82 or pipes, thus ensuring the normal operation of the water supply component 8. At the same time, the cooperation of the locking block 10 and the locking groove 11 makes it easy to disassemble and clean the filter plate 9. The operation is simple and convenient, which can effectively improve the equipment maintenance efficiency and extend the service life of the equipment.

[0031] refer to Figure 1 , Figure 2 and Figure 3 A limiting block 12 is fixedly installed on the rear side of the surface of the cleaning tube 5. A limiting rod 13 is fixedly slidably connected to the bottom of the limiting block 12. A first support block 14 is fixedly connected to the left and right sides of the limiting rod 13. The front of the first support block 14 is fixedly connected to the back of the body 1.

[0032] As a technical optimization of this utility model, the setting of the limiting block 12 and the limiting rod 13 enhances the stability of the cleaning pipe 5 during reciprocating motion, ensuring that the high-pressure nozzle 6 can accurately clean the surface of the conveyor belt 2, thereby improving the cleaning effect and cleaning accuracy.

[0033] refer to Figure 1 , Figure 2 and Figure 3 The left and right sides of the lead screw 72 are movably connected to the second support block 15 via bearings, and the back of the second support block 15 is fixedly connected to the front of the machine body 1.

[0034] As a technical optimization of this utility model, the cooperation between the second support block 15 and the bearing improves the stability and reliability of the rotation of the lead screw 72 and reduces the risk of mechanical failure caused by the lead screw 72 not rotating smoothly.

[0035] The working principle and usage process of this utility model are as follows: During use, the fire door frame to be processed is placed on the conveyor belt 2, and the equipment is started. At this time, the XY axis moving module 3 begins to work. The laser head 4 is positioned on the surface of the XY axis moving module 3. As the module moves, the laser head 4 adjusts its position within the planar space at the top of the machine body 1. The laser head 4 focuses a high-power-density laser beam onto the door frame, using the laser energy to rapidly melt, vaporize, or ablate the door frame material. Simultaneously, a high-speed airflow coaxial with the beam blows away the molten material, thus completing the cutting of the door frame. During the cutting process, the resulting residue falls onto the conveyor belt 2. When the residue on the conveyor belt 2 needs to be cleaned, the water pump 82 is started to extract and pressurize water from the water tank 83, which is then transported to the cleaning pipe 5 through the connecting pipe 81. Multiple high-pressure nozzles 6 connected to the bottom of the cleaning pipe 5 spray water out in a jet pattern under pressure to wash the surface of the conveyor belt 2. Simultaneously, the drive motor 73... The screw 72 is driven to rotate. Since the moving block 71 is threadedly connected to the screw 72, the moving block 71 moves linearly along the screw 72 as the screw 72 rotates. This causes the cleaning pipe 5 to reciprocate along the length of the conveyor belt 2. During the reciprocating movement of the cleaning pipe 5, the high-pressure nozzle 6 continuously sprays water to thoroughly wash the surface of the conveyor belt 2 without any dead angles, completely washing off the attached residue. The washed-off residue and water flow, under the action of gravity, fall into the water tank 83 located at the bottom of the machine body 1 through the through structure. The filter plate 9 at the top of the water tank 83 intercepts and filters the residue in the sewage. The sewage flows into the bottom of the water tank 83 through the filter plate 9 for subsequent centralized treatment. In addition, the limiting block 12 and the limiting rod 13 on the rear side of the surface of the cleaning pipe 5 cooperate to ensure that the cleaning pipe 5 remains stable during the reciprocating movement, avoiding deviation or shaking, and ensuring the cleaning effect. The second support block 15 and the bearing at both ends of the screw 72 ensure the smooth rotation of the screw 72.

[0036] In summary, this laser cutting machine for producing fire door frames improves cleaning efficiency by installing a cleaning pipe 5 with a high-pressure nozzle 6, a reciprocating mechanism 7, and a water supply component 8 at the top of the conveyor belt 2. The water supply component 8 supplies water to the cleaning pipe 5, and the reciprocating mechanism 7 moves the cleaning pipe 5 at the top of the conveyor belt 2. Simultaneously, water is sprayed onto the conveyor belt 2 through the high-pressure nozzle 6, thus completing the cleaning work. This solves the problem of a large amount of residue remaining on the perforated conveyor belt after collecting molten material, requiring regular cleaning and maintenance to ensure normal operation and processing accuracy. Previously, this machine lacked an auxiliary cleaning structure, relying solely on manual cleaning, which was labor-intensive.
