Description

Technical Field

[0001] This utility model relates to the technical field of CNC machining equipment for spiral feed rods, specifically a CNC machining device for a biomass furnace spiral feed rod. Background Technology

[0002] In the production and processing of spiral feed rods for biomass furnaces, CNC machining equipment for spiral feed rods is often required. Utility model patent application number CN201120475682.3 discloses a CNC machining tool for the spiral profile of a twin-screw pump screw. By simply adjusting the extension length of the tool holder and the deflection angle of the tool holder relative to the tool shank, it is possible to machine screws of different specifications, leads, and spiral profiles. Furthermore, by changing the tool head to different materials, it can adapt to the machining of screws of different materials, thus exhibiting good versatility. During machining, the tool head makes point contact with the spiral surface, resulting in minimal wear and high tool head durability and lifespan. With a long lifespan and low cutting force, the cutting speed of the tool can be increased. Furthermore, it can automatically machine three surfaces of the screw's spiral groove in a single setup. Simultaneously, leveraging the high degree of automation of CNC lathes, it improves screw machining efficiency and significantly reduces operator workload. According to its publicly available technical solutions, existing CNC machining equipment for spiral feed rods often suffers from several drawbacks during grinding and polishing. Firstly, it cannot adapt to the screw's outer and inner diameters, hindering rapid fixing and grinding. Secondly, it cannot quickly grind both sides of the spiral plate, reducing work efficiency.

[0003] Therefore, how to design a CNC machining device for the spiral feeder of a biomass furnace has become a problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a CNC machining device for the spiral feed rod of a biomass furnace, so as to solve the problems mentioned in the background art. This utility model is reasonably designed, convenient to use, and suitable for CNC grinding and machining of the spiral feed rod of a biomass furnace.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CNC machining device for a biomass furnace spiral feed rod, comprising a housing and a support roller. A rotating assembly is installed on the housing, the rotating assembly comprising a rotating roller and a first motor. A clamping assembly is installed on the housing, the clamping assembly comprising a second motor and a pressure roller. A lifting assembly is installed on the second motor, the lifting assembly comprising a prism and a lead screw. A sliding assembly is installed on the pressure roller, the sliding assembly comprising a support plate and a slider. A pushing assembly is installed on the support plate, the pushing assembly comprising a third motor and a screw. A grinding assembly is installed on the support plate, the grinding assembly comprising a fourth motor and a grinding roller.

[0006] Furthermore, openings are provided on both sides of the housing, and the support roller and the rotating roller are installed on the inner side of the housing through bearings. The support roller and the rotating roller are respectively installed on both sides of the bottom of the opening. The motor is installed on the outer side of the housing through bolts, and one end of the rotating roller is keyed to the output shaft of the motor.

[0007] Furthermore, the second motor is bolted to the inner wall of the top of the housing, the top of the lead screw is welded to the output shaft of the second motor, and a prism sleeve is bolted to the bottom of the second motor. The inner side of the prism has a threaded opening, which is threaded onto the outer side of the lead screw, and the prism sleeve is fitted onto the outer side of the prism.

[0008] Furthermore, the pressure roller is welded to the bottom end of the prism, and the rotating roller and support roller are symmetrically distributed on both sides of the bottom of the pressure roller.

[0009] Furthermore, the bottom of both ends of the support plate are bolted to the pressure roller, and a slot is provided on the inner side of the support plate, with the slider being locked inside the slot.

[0010] Furthermore, the motor is bolted to the outer side of the support plate, one end of the screw is keyed to the output shaft of the motor, and the other end of the screw passes through the slider and is mounted on the inner side of the support plate through a bearing.

[0011] Furthermore, there are two motors, with the tops of the two motors respectively mounted on the support plate and the bottom of the slider, and each motor has a rib bolt mounted on its output shaft.

[0012] Furthermore, the inner side of the grinding roller is provided with a groove, and the grinding roller is sleeved on the outer side of the rib rod through the groove. The bottom end of the rib rod is connected to the inner wall of the top of the groove by a spring.

[0013] Beneficial effects: 1. When using this CNC machining device for the biomass furnace spiral feeder, the biomass furnace spiral feeder is placed between the support roller and the rotating roller. Motor 2 is turned on, and motor 2 pushes the prism downward under the limit of the prism sleeve through the lead screw. This causes the pressure roller to be clamped on the top of the outer spiral plate of the biomass furnace spiral feeder. The support roller and the rotating roller form a triangular fixation to prevent the biomass furnace spiral feeder from shaking. The pressure roller drives the support plate and the slider to move downward, which causes motor 4 to drive the grinding roller downward to the outer side of the inner round rod on the biomass furnace spiral feeder through the prism. The grinding roller rises on the outer side of the prism through the spring, ensuring that the bottom of the grinding roller is clamped on the outer side of the inner round rod on the biomass furnace spiral feeder. This allows it to adapt to the fixing and grinding work of different outer and inner diameters of the biomass furnace spiral feeder, improving the adaptability of the equipment.

[0014] 2. When using the CNC machining device for the biomass furnace spiral feed rod, first turn on motor three. Motor three drives the slider to move to the left inside the support plate via the screw until the two grinding rollers are respectively clamped on both sides of the spiral plate on the biomass furnace spiral feed rod. Then turn on motor four. Motor four drives the grinding roller to simultaneously grind both sides of the spiral plate via the prism rod, eliminating the need to grind both sides of the spiral plate separately, thus improving work efficiency. Motor one drives the rotating roller to rotate, which in turn drives the biomass furnace spiral feed rod to rotate. The spiral plate on the biomass furnace spiral feed rod rotates spirally between the two grinding rollers, causing the biomass furnace spiral feed rod to move spirally from right to left in the box, thereby effectively performing synchronous grinding work on the spiral plate and the inner round rod component on the biomass furnace spiral feed rod, improving processing efficiency.

[0015] 3. The CNC machining device for the biomass furnace screw feeder is reasonably designed, highly efficient and convenient to use, and suitable for CNC grinding of the biomass furnace screw feeder. Attached Figure Description

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] Please see Figures 1 to 4This utility model provides a technical solution: a CNC machining device for a biomass furnace spiral feed rod, comprising a housing 1 and a support roller 2. A rotating assembly is mounted on the housing 1, the rotating assembly including a rotating roller 3 and a motor 4. A clamping assembly is mounted on the housing 1, the clamping assembly including a motor 6 and a pressure roller 5.

The pushing assembly includes a third motor 12 and a screw 13. A grinding assembly is mounted on the support plate 10, which includes a fourth motor 14 and a grinding roller 15. A second motor 6 is bolted to the inner wall of the top of the housing 1. The top end of the lead screw 8 is welded to the output shaft of the second motor 6. A prism sleeve 7 is bolted to the bottom of the second motor 6. A threaded opening is provided on the inner side of the prism 9, and the threaded opening is threaded onto the outer side of the lead screw 8. The prism sleeve 7 is fitted onto the outer side of the prism 9. The pressure roller 5 is welded to the bottom end of the prism 9. The rotating roller 3 and the support roller 2 are symmetrically distributed on both sides of the bottom of the pressure roller 5. The bottom ends of both ends of the support plate 10 are bolted to the pressure roller 5. A slot is provided on the inner side of the support plate 10, and the slider 11 is locked inside the slot. In use, the biomass furnace spiral feed rod is placed between the support roller 2 and the rotating roller 3, and the motor 6 is turned on. The motor 6 pushes the prism 9 downward under the limit of the prism sleeve 7 through the lead screw 8, thereby driving the pressure roller 5 to lock onto the top of the outer spiral plate of the biomass furnace spiral feed rod, and forming a three-phase structure through the support roller 2 and the rotating roller 3. The corner is fixed to prevent the biomass furnace screw feed rod from shaking. The pressure roller 5 drives the support plate 10 and the slider 11 to move downward, which in turn causes the motor 14 to drive the grinding roller 15 downward to the outer side of the inner round rod on the biomass furnace screw feed rod through the rib 16. The grinding roller 15 rises on the outer side of the rib 16 through the spring 17, ensuring that the bottom of the grinding roller 15 is locked on the outer side of the inner round rod on the biomass furnace screw feed rod. This allows it to adapt to different outer and inner diameters of the biomass furnace screw feed rod for fixing and grinding, improving the adaptability of the equipment.

[0023] In this embodiment, openings are provided on both sides of the housing 1. The support roller 2 and rotating roller 3 are mounted on the inner side of the housing 1 via bearings. The support roller 2 and rotating roller 3 are respectively mounted on both sides of the bottom of the openings. Motor 4 is bolted to the outer side of the housing 1. One end of the rotating roller 3 is keyed to the output shaft of motor 4. Motor 3 12 is bolted to the outer side of the support plate 10. One end of the screw 13 is keyed to the output shaft of motor 3 12. The other end of the screw 13 passes through the slider 11 via a thread and is mounted on the inner side of the support plate 10 via a bearing. There are two motors 4 14. The tops of the two motors 4 14 are respectively mounted on the bottom of the support plate 10 and the slider 11. Rib rods 16 are bolted to the output shafts of each motor 4 14. A groove is provided on the inner side of the grinding roller 15. The grinding roller 15 is fitted onto the outer side of the rib rod 16 through the groove. The bottom end of the rib 16 is connected to the inner wall of the top of the rib groove via a spring 17. In use, motor 3 12 is turned on, and motor 3 12 drives the slider 11 to move to the left inside the support plate 10 via screw 13 until the two grinding rollers 15 are respectively clamped on both sides of the spiral plate on the biomass furnace spiral feed rod. Then motor 4 14 is turned on, and motor 4 14 drives the grinding rollers 15 to grind both sides of the spiral plate simultaneously via the rib 16. There is no need to grind both sides of the spiral plate separately, which improves work efficiency. Motor 1 4 drives the rotating roller 3 to rotate, which in turn drives the biomass furnace spiral feed rod to rotate. The spiral plate on the biomass furnace spiral feed rod rotates spirally between the two grinding rollers 15, so that the biomass furnace spiral feed rod moves spirally from right to left inside the box 1, thereby effectively grinding the spiral plate and the inner round rod component on the biomass furnace spiral feed rod simultaneously, improving processing efficiency.

[0024] The CNC machining device for the biomass furnace spiral feeder provides power to all electrical equipment via an external power supply. During operation, the biomass furnace spiral feeder is placed between the support roller 2 and the rotating roller 3. Motor 6 is turned on, and it drives the prism 9 downwards via the lead screw 8, which is limited by the prism sleeve 7. This causes the pressure roller 5 to clamp onto the top of the outer spiral plate of the biomass furnace spiral feeder. The support roller 2 and the rotating roller 3 form a triangular fixation to prevent the biomass furnace spiral feeder from shaking. The pressure roller 5 drives the support plate 10 and the slider 11 downwards, causing motor 14 to drive the grinding roller 15 downwards via the prism 16 to the outer side of the inner circular rod on the biomass furnace spiral feeder. The grinding roller 15 rises on the outer side of the prism 16 via the spring 17, ensuring that the bottom of the grinding roller 15 is clamped onto the outer side of the inner circular rod on the biomass furnace spiral feeder. This allows it to adapt to different biomass furnace spiral feeder configurations. The outer and inner diameters are fixed and ground to improve the adaptability of the equipment. Then, motor 312 is turned on. Motor 312 drives slider 11 to move to the left inside the support plate 10 through screw 13 until the two grinding rollers 15 are respectively clamped on both sides of the spiral plate on the biomass furnace spiral feed rod. Then, motor 414 is turned on. Motor 414 drives grinding roller 15 to grind both sides of the spiral plate simultaneously through rib rod 16. There is no need to grind both sides of the spiral plate separately, which improves the working efficiency. Motor 14 drives roller 3 to rotate, which in turn drives the biomass furnace spiral feed rod to rotate. The spiral plate on the biomass furnace spiral feed rod rotates spirally between the two grinding rollers 15, so that the biomass furnace spiral feed rod moves spirally from right to left in the box 1, thereby effectively grinding the spiral plate and the inner round rod component on the biomass furnace spiral feed rod simultaneously, improving the processing efficiency.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
