[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Reference Figure 1 、 Figure 2 and Figure 4The utility model provides an embodiment: a cutting machine, including an outer frame 1, which is the main frame structure of the entire cutting machine and plays the role of supporting and protecting internal components. The rear side of the inner bottom wall of the outer frame 1 is fixedly connected with a rotating motor 3. The rotating motor 3 provides a power source for the entire cutting process. The output end of the rotating motor 3 is fixedly connected with a driving gear 4. The driving gear 4 transmits the power of the rotating motor 3. The middle and upper parts of the front and rear sides of the inner wall of the outer frame 1 are rotatably connected with a driven wheel 5. The driven wheel 5 rotates under the drive gear 4. The driven wheel 5 is meshed with the driving gear 4. The power is transmitted in this meshing manner. The front side of the outer wall of the driven wheel 5 is fixedly connected with a cutting blade 6. The cutting blade 6 is the main component for realizing the cutting function. The middle and upper part of the cutting blade 6 passes through the outer frame 1. The middle part of the front side of the top wall of the frame 1 is used for cutting external materials. The four corners of the bottom wall of the outer frame 1 are fixedly connected with columns 7. The columns 7 are used to support the outer frame 1 and all components above it. The bottom ends of multiple columns 7 are fixedly connected with a base plate 8. The base plate 8 provides a stable placement plane for the entire cutting machine. The front side of the top wall of the base plate 8 is fixedly connected with an exhaust fan 9. The exhaust fan 9 generates suction to extract the sawdust generated during the cutting process. The output end of the exhaust fan 9 is connected to a sawdust collection box 10 through a quick disassembly component 1. The sawdust collection box 10 is used to collect the sawdust extracted by the exhaust fan 9. The rear side of the sawdust collection box 10 is connected to an exhaust pipe 11 through a quick disassembly component 2. The exhaust pipe 11 transports the sawdust at the dust collection cover 12 to the sawdust collection box 10 The front end of the exhaust pipe 11 is fixedly connected with a dust collection cover 12. The dust collection cover 12 is located just above the cutting blade 6 and is used to collect sawdust generated when the cutting blade 6 cuts the material. The rear side of the inner wall of the sawdust collection box 10 is fixedly connected with a filter screen 13. The filter screen 13 can preliminarily filter out larger particles of impurities in the sawdust. The front side of the filter screen 13 is fixedly connected with a filter cotton 14. The filter cotton 14 further filters fine sawdust particles to ensure that the discharged gas is relatively clean. The middle part of the top wall of the bottom plate 8 is provided with a collection box replacement mechanism 2. The collection box replacement mechanism 2 can quickly and easily replace the sawdust collection box 10 to improve work efficiency.

[0040] Specifically, the rotating motor 3 on the rear side of the inner bottom wall of the outer frame 1 is started, and its output end drives the driving gear 4 to rotate. Since the driving gear 4 is meshed and connected with the driven wheel 5 on the middle and upper part of the front and rear sides of the inner wall of the outer frame 1, the rotation of the driving gear 4 will drive the driven wheel 5 to rotate, and the cutting blade 6 on the front side of the outer wall of the driven wheel 5 will rotate accordingly. When the material to be cut approaches and contacts the high-speed rotating cutting blade 6, the cutting operation is realized, and a large amount of sawdust will be generated during the cutting process. At this time, the exhaust fan 9 located on the front side of the top wall of the bottom plate 8 starts to work, and the sawdust generated above the cutting blade 6 is sucked into the dust collection cover 12 at the front end of the exhaust pipe 11 The sawdust passes through the exhaust pipe 11 and the output end of the exhaust fan 9 in turn, and then enters the sawdust collection box 10 through the quick disassembly component 1. The sawdust entering the sawdust collection box 10 will first encounter the filter 13. The filter 13 can block larger particles of impurities, and the filter cotton 14 on the front side of the filter 13 further filters the fine sawdust particles to ensure that the discharged gas is relatively clean and reduces pollution to the environment. The column 7 plays the role of supporting the outer frame 1 and stabilizing the entire cutting machine. The setting of the quick disassembly component 1 and the quick disassembly component 2 facilitates the disassembly and cleaning of the sawdust collection box 10, ensuring the continuous and efficient operation of the cutting machine.

[0041] Reference Figure 1 、 Figure 3 and Figure 5 The collection box replacement mechanism 2 includes two slide rails 201 for guiding the movement of the sawdust collection box 10. The bottom wall of the sawdust collection box 10 is provided with two slide grooves 202. The slide grooves 202 are designed to cooperate with the slide rails 201 so that the sawdust collection box 10 can slide smoothly. The two slide grooves 202 are slidably connected to the two slide rails 201 respectively. Through this connection method, the sawdust collection box 10 can slide freely on the slide rails 201, which is convenient for replacement operation. The left end of the top wall of the bottom plate 8 is fixedly connected to a fixed platform 203. The fixed platform 203 plays the role of fixing the sawdust collection box 10 to ensure its stability during work. The left side of the sawdust collection box 10 is fixedly connected to two fixed protrusions 204.

The middle part of the top wall of the two fixing protrusions 204 and the front and rear sides of the top wall of the fixing platform 203 are provided with fixing grooves 205. The fixing grooves 205 are for installing fixing bolts 206 so that the fixing protrusions 204 and the fixing platform 203 can be tightly connected. The inner walls of the two fixing grooves 205 at the front end and the two fixing grooves 205 at the rear end are penetrated by fixing bolts 206. The fixing bolts 206 pass through the fixing grooves 205 to firmly fix the sawdust collection box 10 on the fixing platform 203 to prevent it from moving during work. A push rod 207 is fixedly connected to the right side of the sawdust collection box 10. The push rod 207 is convenient for the operator to push it when replacing the sawdust collection box 10, making the replacement process easier and more convenient.

[0042] Specifically, when the sawdust collecting box 10 needs to be replaced, the push rod 207 is pushed first. Since the two slide grooves 202 on the bottom wall of the sawdust collecting box 10 are slidably connected to the two slide rails 201 on the bottom plate 8, the sawdust collecting box 10 will slide to the right along the slide rails 201 under the action of the thrust. As the sawdust collecting box 10 moves, the two fixed protrusions 204 fixedly connected on the left side will gradually break away from the connection with the fixed platform 203. When the fixing grooves 205 on the fixing protrusions 204 are completely staggered with the fixing grooves 205 on the fixed platform 203, the sawdust collecting box 10 can be removed from the bottom plate 8. When a new sawdust collecting box 10 is installed, the sawdust collecting box 10 will be removed from the bottom plate 8. The slide groove 202 on the bottom wall of the box 10 is aligned with the slide rail 201, and then the sawdust collection box 10 is pushed to the left so that it slides to the left along the slide rail 201. When the fixed protrusion 204 on the left side of the sawdust collection box 10 contacts the fixed platform 203, the position is adjusted so that the fixed groove 205 in the middle of the top wall of the fixed protrusion 204 is aligned with the fixed grooves 205 on the front and rear sides of the top wall of the fixed platform 203. Then, the fixing bolts 206 are inserted into the aligned fixing grooves 205 and tightened. The sawdust collection box 10 is thereby firmly fixed to the base plate 8, making the replacement of the sawdust collection box 10 convenient and quick, thereby improving the efficiency and convenience of using the cutting machine.

[0043] Reference Figure 3 and Figure 5 , the quick disassembly component 1 includes a bending tube 15, the bending tube 15 is used to connect the output end of the vacuum pump 9 and change the direction of the air flow, and is connected to the output end of the vacuum pump 9. The vacuum pump 9 provides suction power for the entire system. A threaded ring 16 is fixedly connected to the rear side of its outer wall. The threaded ring 16 is used to be threadedly connected to the connecting tube 18. A connector 17 is fixedly installed in the middle of the front side of the sawdust collection box 10. The connector 17 is used to connect the bending tube 15 and the sawdust collection box 10. The outer wall of the bending tube 15 is threadedly connected to a connecting tube 18. The connecting tube 18 is connected to the bending tube 15 and The connection of the connector 17, the rear end of the inner wall of the connecting pipe 18 is threadedly connected to the outer wall of the connector 17, thereby completing the quick disassembly connection between the bending pipe 15 and the sawdust collection box 10; the quick disassembly component 2 includes a connector 2 19, the connector 2 19 is used to connect the exhaust pipe 11 and the sawdust collection box 10, and is fixedly installed in the middle of the rear side of the sawdust collection box 10. The position of the connector 2 19 on the sawdust collection box 10 is determined, and the bottom end of the exhaust pipe 11 is threadedly connected to the inner wall of the sawdust collection box 10. The quick disassembly connection between the exhaust pipe 11 and the sawdust collection box 10 is achieved through the threaded connection;

[0044] Specifically, the bent tube 15 serves as a transition connection component between the output end of the vacuum pump 9 and the connecting tube 18, transmitting the suction force generated by the vacuum pump 9 to the connecting tube 18, thereby guiding the sawdust into the sawdust collection box 10. The threaded ring 16 is convenient for threaded connection with the connecting tube 18. The connector 17 is fixed to the middle of the front side of the sawdust collection box 10 and cooperates with the connecting tube 18 to realize the rapid connection and disconnection between the sawdust collection box 10 and the vacuum pump 9, which is convenient for cleaning or replacing the sawdust collection box. 10, the operation is performed, the connecting pipe 18 is connected between the bending pipe 15 and the connecting head 17 by a thread, which plays the role of conducting airflow and sawdust, and the connecting head 2 19 is installed in the middle of the rear side of the sawdust collecting box 10, providing a connection point for the exhaust pipe 11, so that the exhaust pipe 11 can be quickly connected and disassembled with the sawdust collecting box 10, and the exhaust pipe 11 transports the sawdust collected at the dust collection cover 12 to the sawdust collecting box 10, and the threaded connection at the bottom end is convenient for quick disassembly and installation when needed.

[0045] Reference Figure 1 、 Figure 2 and Figure 3 The top of the push rod 207 is fixedly connected with an anti-slip sleeve 20, which can increase friction and prevent the hand from slipping when pushing. Its outer wall is frosted, which further improves the anti-slip effect; the four corners of the bottom wall of the bottom plate 8 are fixedly connected with anti-slip pads 21. The anti-slip pads 21 can enhance the friction between the entire device and the ground and improve stability. The multiple anti-slip pads 21 are all conical structures with a small top and a large bottom. This structure can increase the contact area and improve stability; the top wall of the outer frame 1 is fixedly connected to the rear end side and the rear end of the top wall with storage partitions 22. The storage partitions 22 are used to separate different material areas for easy storage and management. The two storage partitions 22 are parallel to each other to ensure that the separated areas are regular; the middle part of the top wall of the outer frame 1 is fixedly connected with a scale 23. The scale 23 is convenient for the operator to read relevant data intuitively. It is a physical welding process to ensure that the scale 23 is firm and durable and not easy to damage;

[0046] Specifically, the outer wall of the anti-slip sleeve 20 is frosted, which increases the friction and makes the operator more stable and less likely to slip when pushing the push rod 207. The anti-slip pad 21 at the bottom of the base plate 8 adopts a conical structure with a small top and a large bottom, which increases the contact area and friction with the ground and prevents the cutting machine from sliding during operation. The material storage partition 22 is fixed to the top wall of the outer frame 1 near the rear end and the rear end of the top wall. The two parallel material storage partitions 22 can prevent the cutting material from slipping during the cutting process. At the same time, they can also limit the cutting material to a certain extent, which is convenient for the operator to perform cutting operations. The scale 23 is fixed to the middle of the top wall of the outer frame 1 using a physical welding process, which can provide a measurement reference for the cutting operation, help the operator accurately control the cutting size and accuracy, and improve the cutting quality.

[0047] Working principle: start the rotating motor 3 on the rear side of the inner bottom wall of the outer frame 1, and its output end drives the driving gear 4 to rotate. Since the driving gear 4 is meshed and connected with the driven wheel 5 on the middle and upper part of the front and rear sides of the inner wall of the outer frame 1, the rotation of the driving gear 4 will drive the driven wheel 5 to rotate, and the cutting blade 6 on the front side of the outer wall of the driven wheel 5 rotates accordingly. When the material to be cut approaches and contacts the high-speed rotating cutting blade 6, the cutting operation is realized, and a large amount of sawdust will be generated during the cutting process. At this time, the air exhauster 9 located on the front side of the top wall of the bottom plate 8 starts to work, and the sawdust generated above the cutting blade 6 is sucked in through the dust collection cover 12 at the front end of the exhaust pipe 11. The sawdust passes through the exhaust pipe 11 and the output end of the air exhauster 9 in turn, and then enters the sawdust collection box 10 through the quick disassembly component 1. The sawdust entering the sawdust collection box 10 will first encounter the filter screen 13. The filter screen 13 can block larger particles of impurities, and the filter cotton 14 on the front side of the filter screen 13 further filters the fine sawdust particles, ensuring that the discharged gas is relatively clean and reduces pollution to the environment;

[0048] Furthermore, when the sawdust collecting box 10 needs to be replaced, the push rod 207 is pushed first. Since the two slide grooves 202 on the bottom wall of the sawdust collecting box 10 are slidably connected to the two slide rails 201 on the bottom plate 8, the sawdust collecting box 10 will slide to the right along the slide rails 201 under the action of the thrust. As the sawdust collecting box 10 moves, the two fixed protrusions 204 fixedly connected to the left side will gradually break away from the connection with the fixed platform 203. When the fixed grooves 205 on the fixed protrusions 204 are completely offset from the fixed grooves 205 on the fixed platform 203, the sawdust collecting box 10 can be removed from the bottom plate 8 and installed. When installing a new sawdust collection box 10, align the slide groove 202 on the bottom wall of the sawdust collection box 10 with the slide rail 201, and then push the sawdust collection box 10 to the left so that it slides to the left along the slide rail 201. When the fixed protrusion 204 on the left side of the sawdust collection box 10 contacts the fixed platform 203, adjust the position so that the fixed groove 205 in the middle of the top wall of the fixed protrusion 204 is aligned with the fixed grooves 205 on the front and rear sides of the top wall of the fixed platform 203, and then insert the fixing bolts 206 into the aligned fixing grooves 205 and tighten the fixing bolts 206 to firmly fix the sawdust collection box 10 on the base plate 8.
