When the large pieces of wood waste move in the device, they can cause blockages, leading to jamming. This requires frequent repairs by the staff, wasting time, increasing operating costs, and reducing production efficiency. Therefore, it is necessary to improve the dust blowing device of wood CNC processing equipment to solve the above problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5 This utility model provides an embodiment of a dust blowing device for a CNC wood processing equipment, comprising a housing 1, and further comprising a wood waste shell 23 disposed on the housing 1, a feed inlet 2 fixedly connected to the wood waste shell 23, a drive shaft 210 rotatably connected to the wood waste shell 23, a driven shaft 213 rotatably connected to the wood waste shell 23, blades 28 fixedly connected to the drive shaft 210, a fan 26 fixedly connected to the housing 1, a material distribution plate 212 fixedly connected to the wood waste shell 23, a conveying pipe 22 fixedly connected between the wood waste shell 23 and the feed inlet 2, a material distribution net 211 disposed on the conveying pipe 22, and a blowing hose disposed on the housing 1. Pipe 214, storage component on housing 1, and transmission component on one side of housing 1, block larger wood blocks through distribution net 211, and then distribution plate 212 guides the larger wood blocks to blades 28. Fan 26 rotates to suck air out of wood waste shell 23. Under the action of air pressure, wood waste enters from inlet 2. Distribution net 211 blocks larger wood waste, causing it to fall onto blades 28 under the action of distribution plate 212. Blades 28 rotate to break up the larger wood waste, which then falls from discharge pipe 24 into drawer 32. Fan 26 blows gas out from air blowing hose 214, blowing the wood waste into the air, making it easier to be sucked into inlet 2.

[0022] Please see Figures 1-2In this embodiment, a discharge pipe 24 is fixedly connected between the housing 1 and the wood waste shell 23. A dustproof net 25 is provided at the air inlet of the fan 26. An air outlet 27 is provided on the fan 26 and is fixedly connected to the housing 1. An isolation door 29 is rotatably connected to the wood waste shell 23. Small pieces of wood waste pass through the discharge pipe 24. The dustproof net 25 prevents wood waste from flowing into the fan 26 and clogging the fan 26, thus weakening its airflow. When the blade 28 is stuck by an overly hard object, the isolation door 29 can be opened to repair the blade 28. There are two driven shafts 213 and two driven shafts 210 respectively, and blades 28 are installed on both driven shafts 213 and driven shafts 210. The blades 28 on the driven shaft 210 and driven shaft 213 are staggered to prevent larger pieces of wood waste from passing through the gaps.

[0023] Please see Figures 1-3 In this embodiment, the storage component includes a storage shell 3 located at the bottom of the discharge pipe 24, a drawer 32 slidably connected inside the storage shell 3, a water tank 34 fixedly connected to the storage shell 3, a nozzle 33 located on the water tank 34, a water pump located between the water tank 34 and the nozzle 33, and a dust cover 35 located on the water tank 34. When the wood waste in the storage shell 3 is full, the drawer 32 can be removed from the inlet 2 to empty the wood waste. A pressurizing device is installed between the water tank 34 and the nozzle 33 to pressurize the water in the water tank 34 and spray it out in a mist from the nozzle 33, increasing the humidity of the wood waste in the storage shell 3 and preventing the wood waste from exploding due to high concentration. The nozzles 33 are arranged in a linear array on the water tank 34 and are located between the water tank 34 and the storage shell 3. Multiple nozzles 33 spray the crushed wood waste in the storage shell 3 without dead angles, ensuring that the humidity is maintained at a safe level.

[0024] Please see Figures 4-5In this embodiment, the transmission assembly includes a motor 12 disposed on one side of the housing 1, a drive wheel 13 fixedly connected to the output end of the housing 1, a first transmission shaft 110 fixedly connected to the output end of the motor 12, a driven wheel 15 fixedly connected to the drive shaft 210, a first belt 14 drivingly connected between the driven wheel 15 and the drive wheel 13, a coaxial wheel 16 fixedly connected to the drive shaft 210, a second belt 17 rotatably connected to the coaxial wheel 16, a drive gear 18 fixedly connected to the drive shaft 210, and a drive gear 18 fixedly connected to the driven shaft 213. The driven gear 19 and the driving gear 18 mesh with each other. The motor 12 transmits power to the driving shaft 210 and the driven shaft 213 through the first belt 14 and the second belt 17. The driven shaft 213 and the driving shaft 210 drive the blades 28 to rotate. The driving gear 18 meshes with the driven gear 19, causing the driving shaft 210 and the driven shaft 213 to rotate in opposite directions, so that the opposite blades 28 rotate in opposite directions to achieve a stronger pulverizing effect. The first drive shaft 110 reaches the fan blades inside the blower 26 to rotate, thereby realizing the suction and exhaust of air. There are two coaxial pulleys 16, which are fixedly connected to the two driving shafts 210 respectively. The second belt 17 drives the connection between the two coaxial pulleys 16. When the blades 28 are stuck by hard foreign objects, the coaxial pulleys 16 will slip or break, thus effectively protecting the device.

[0025] During operation, motor 12 is started, driving the first drive shaft 110 to rotate. The rotating first drive shaft 110 drives the fan blades inside the blower 26 to rotate, and the blower 26 delivers gas to the air outlet 27. The air outlet 27 blows the gas out through the air blowing hose 214, which agitates the wood waste. The rotating fan blades extract air from the wood waste shell 23. The first drive shaft 110 drives the drive wheel 13 to rotate, and the drive wheel 13 transmits power to the driven wheel 15. The driven wheel 15 drives the drive shaft 210 to rotate, and the drive shaft 210 drives the coaxial wheel 16 to rotate. The coaxial wheel 16 transmits power to another coaxial wheel 16 and another drive shaft 210 through the second belt 17. The drive shaft 210 drives the drive gear 18 to rotate. 18 transmits power to driven gear 19, which drives driven shaft 213 to rotate. Drive shaft 210 and driven shaft 213 drive blade 28 to rotate. Feed inlet 2 draws in outside air and wood waste. Small wood waste passes through distribution net 211 and conveying pipe 22 to wood waste shell 23. Wood waste falls from wood waste shell 23 to discharge pipe 24 and into storage shell 3. Larger pieces of wood waste are blocked by distribution net 211 and fall onto distribution plate 212. Distribution plate 212 guides larger pieces of wood waste to rotating blade 28. Rotating blade 28 crushes the larger pieces of wood waste and then they fall from discharge pipe 24 into storage shell 3. Spray nozzle 33 sprays water into storage shell 3 in a mist to increase the humidity of wood waste.

[0026] Through the above steps, larger pieces of wood waste are blocked by the separating net 211 and fall onto the separating plate 212. The separating plate 212 guides the larger pieces of wood waste to the rotating blades 28, which crush the larger pieces of wood waste. This solves the problem that the dust blowing device of the wood CNC processing equipment will suck in larger pieces of wood waste during operation, and that the larger pieces of wood waste will cause blockage and jam the device when moving in the device.
