Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, and in particular to an automatic flash cutting device for wind turbine blades. Background Art

[0002] Wind turbine blades are key components of wind turbines. In order to realize the molding process and facilitate blade demoulding, the mold design will add a flange edge that is not an effective part. After the wind turbine blade is formed, a part of the flash that is not the blade body will be produced due to the existence of the mold flange edge, which needs to be cut off later.

[0003] As wind turbine blades are currently manufactured in a trend toward larger and longer sizes, the length of mainstream wind turbine blades is generally over 100m. The flash on the side is also over 100m long because it is demolded and removed from the production line together with the wind turbine blades.

Both ends of each rotating shaft rotate through the fixed seat, and each rolling wheel is fixedly sleeved on the outer surface of the corresponding end of the rotating shaft.

[0009] As a further technical solution of the present invention, the driving assembly includes two driving shafts rotatably arranged on the inner wall of the cavity, the outer surface of each driving shaft is fixedly sleeved with a small gear ring, the outer surface of each rotating shaft is fixedly sleeved with a large gear ring, each large gear ring is meshingly connected with the adjacent small gear ring, the outer surfaces of the two driving shafts are fixedly sleeved with a pulley, a transmission belt is sleeved between the two pulleys, and a motor for driving one of the driving shafts to rotate is arranged on one side of the fixed seat.

[0010] As a further technical solution of the present invention, two rotating shafts 2 are symmetrically arranged on the side wall of the fixed seat 2, each roller wheel 2 is fixedly sleeved on the outer surface of the corresponding rotating shaft 2, each linkage unit 1 includes two pulleys 2, each pulley 2 is fixedly sleeved on the outer surface of the corresponding rotating shaft 1 and rotating shaft 2, and a transmission belt 2 is sleeved between the corresponding two pulleys 2.

[0011] As a further technical solution of the present invention, an exhaust hood is fixed between the first fixing seat and the second fixing seat, a vacuum cleaner is fixed to the upper end surface of the lifting platform, and a ventilation hose is provided between the vacuum cleaner and the exhaust hood.

[0012] As a further technical solution of the present invention, support frames are fixed to the lower end surface of the upper top plate 1 and the upper end surface of the lifting platform, mounting seats are fixed to the opposite surfaces of the two support frames, a rotating shaft 3 is rotatably provided on the side wall of each mounting seat, a brush ring is fixedly sleeved on the outer surface of each rotating shaft 3, each brush ring is in contact with the surface of the corresponding roller wheel 1, and a linkage unit 2 is provided between each rotating shaft 1 and the corresponding rotating shaft 3.

[0014] As a further technical solution of the present invention, an upper top plate 2 is fixed to the upper end surface of the fixed seat 2, a connecting plate is fixed to the lower end surface of the upper top plate 2 and the upper end surface of the lifting platform, a mounting plate is fixed to one side of each connecting plate, and brush layers are fixed to the opposite surfaces of the two mounting plates.

[0015] As a further technical solution of the present invention, a connecting rod is fixed to the outer surface of each of the rotating shafts three, and a collision protrusion is fixed to the end of each connecting rod.

[0016] Beneficial effects of the present invention: 1. When in use, after the wind turbine blade to be processed is placed flat at the designated position, the automatic guided vehicle moves to one side of the wind turbine blade, and then the lifting platform drives the fixing seat 1 and the fixing seat 2 to rise to an appropriate height, and then the automatic guided vehicle moves along the length direction of the wind turbine blade (until it circles the wind turbine blade). During the movement, under the action of the driving component and the linkage unit 1, the two roller pressing wheels 1 and the two roller pressing wheels 2 are prompted to rotate. In the process of following the movement of the automatic guided vehicle, the two roller pressing wheels 1 first roll and clamp to the edge of the burr of the wind turbine blade, and take over the end of the burr away from the wind turbine blade, and then the two roller pressing wheels 2 also roll and clamp to the burr, and further The cutting blade is moved to contact the upper surface of the burr during this process. The cutting machine is in a power-off state. When the two roller pressing wheels 1 and the two roller pressing wheels 2 are rolled and clamped to the burr, the cutting machine drives the cutting blade to rotate, so that the cutting blade can separate the end of the burr close to the wind turbine blade from the wind turbine blade. During the cutting process, the two roller pressing wheels 1 and the two roller pressing wheels 2 always follow the movement to roll and clamp the end part of the burr, so that the cutting blade can better exert force on the burr, avoiding the burr from bending downward during the cutting process, which affects the normal cutting operation. It is easy to use.

[0017] 2. In the initial state, dust will fall on the wind turbine blades to be processed. Similarly, dust will also fall on the flash of the wind turbine blades. After the roller wheel 1 rolls on the surface of the flash, the surface of the roller wheel 1 will also adhere to the dust. Since the brush ring is in contact with the corresponding surface of the roller wheel 1, the brush ring can scrape off the dust on the surface of the roller wheel 1 in a rotating state, avoiding excessive dust adhesion on the surface of the roller wheel 1, reducing the friction between the roller wheel 1 and the flash, affecting the rolling conveying of the roller wheel pair of flashes, and the roller wheel 1 and the rotating shaft 1 will drive the corresponding large pulley 3 to rotate during the rotation process, thereby driving the corresponding rotating shaft 3 and the brush ring to rotate through the transmission belt 3. When the rotating brush ring wipes and cleans the surface of the roller wheel 1, it can cooperate with the exhaust hood to suck away the wiped dust in time.

[0018] 3. When in use, the two brush layers are in contact with the upper and lower surfaces of the burrs respectively. When the burrs pass through the brush layers, the brush layers will wipe and clean the remaining dust adhering to the surface of the burrs to prevent further dust from adhering to the surface of the burrs when the subsequent roller of the pressing wheel 2 is pressed on the surface of the burrs. The brush layers will scrape up the dust adhering to the surface of the burrs, and cooperate with the exhaust hood to suck away the scraped dust. In addition, when the rotating shaft three and the brush ring are rotating, the rotating shaft three will drive the connecting rod and the collision protrusion to rotate. During the process of following the rotation, the collision protrusion will collide with the corresponding connecting plate, thereby causing the connecting plate, the mounting plate and the brush layer to vibrate, thereby shaking off the dust adhering to the surface of the brush layer, and cooperating with the exhaust hood to suck the dust into the vacuum cleaner.

During the rotation of the driving shaft 14, the small gear ring 15 is driven to rotate, thereby causing the large gear ring 16, the rotating shaft 13 and the roller wheel 4 to rotate.

The brush layers 36 will scrape up the dust adhering to the surface of the burrs, and cooperate with the exhaust hood 23 to suck away the scraped dust. In the process of rotation of the rotating shaft three 28 and the brush ring 29, the rotating shaft three 28 will drive the connecting rod 37 and the collision protrusion 38 to rotate. In the process of following the rotation, the collision protrusion 38 will collide with the corresponding connecting plate 34, thereby causing the connecting plate 34, the mounting plate 35 and the brush layer 36 to vibrate, thereby shaking off the dust adhering to the surface of the brush layer 36, and cooperating with the exhaust hood 23 to suck the dust into the vacuum cleaner 24.

Reference Figure 3 , Figure 5 and Fig. 9In the initial state, dust will fall on the wind turbine blades to be processed. Similarly, dust will also fall on the flash of the wind turbine blades. After the roller wheel 4 is rolled on the surface of the flash, the surface of the roller wheel 4 will also adhere to the dust. Since the brush ring 29 is in contact with the corresponding surface of the roller wheel 4, the brush ring 29 can scrape off the dust on the surface of the roller wheel 4 in the rotating state, avoid excessive dust adhering to the surface of the roller wheel 4, reduce the friction between the roller wheel 4 and the flash, and affect the rolling conveying of the roller wheel 4 to the flash. In the process of rotation, the roller wheel 4 and the rotating shaft 13 will drive the corresponding large pulley three 30 to rotate, thereby driving the corresponding rotating shaft three 28 and the brush ring 29 to rotate through the transmission belt three 32. When the rotating brush ring 29 wipes and cleans the surface of the roller wheel 4, it can cooperate with the exhaust hood 23 to suck away the wiped dust in time; Reference Figure 3 , Figure 5 , Fig. 9 and Fig.10 When in use, the two brush layers 36 are in contact with the upper and lower surfaces of the burrs respectively. When the burrs pass through the brush layers 36, the brush layers 36 will wipe and clean the remaining dust adhering to the surface of the burrs to prevent further dust from adhering to the surface of the burrs when the subsequent roller pressing wheel 26 is rolled on the surface of the burrs. The brush layers 36 will scrape up the dust adhering to the surface of the burrs, and cooperate with the exhaust hood 23 to suck away the scraped dust. In the process of rotation of the rotating shaft three 28 and the brush ring 29, the rotating shaft three 28 will drive the connecting rod 37 and the collision protrusion 38 to rotate. In the process of following the rotation, the collision protrusion 38 will collide with the corresponding connecting plate 34, thereby causing the connecting plate 34, the mounting plate 35 and the brush layer 36 to vibrate, thereby shaking off the dust adhering to the surface of the brush layer 36, and cooperating with the exhaust hood 23 to suck the dust into the vacuum cleaner 24.
