[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0024] The technical solutions disclosed in each embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Please refer to Figures 1 to 6 , an embodiment of the present invention discloses a blade cutting device, and the disclosed blade cutting device includes a device frame 100, a waste water collection module 200, and a water jet cutting device 300.

[0026] The device frame 100 is the basis for installing at least some other components of the blade cutting device.

[0027] The waste water collection module 200 includes a water receiving tray 210 and a waste water tank 220. The water receiving tray 210 is used to collect the waste water generated when the water jet cutting device 300 cuts the blade A, and the waste water tank 220 is used to store the waste water collected by the water receiving tray 210.

[0028] The water jet cutting device 300 includes a cutting head driving module 310 and a water knife cutting head 320. The cutting head driving module 310 is arranged on the device frame 100, the cutting head driving module 310 is connected to the water knife cutting head 320, and the cutting head driving module 310 is used to drive the water knife cutting head 320 to move to cut the blade A.

[0029] The water receiving tray 210 is arranged on the device frame 100 and is located below the water knife cutting head 320, and the waste water tank 220 is arranged on the device frame 100 and is connected to the water receiving tray 210.

[0030] It should be noted that the working principle of the water jet cutting device 300 is as follows: The water is pressurized to 200 - 400 Mpa to make the water have a huge pressure energy and is sent to a nozzle with a very small aperture, and abrasive is added and mixed, and then it is ejected at a high speed above twice the speed of sound. The cutting of the material is achieved through the erosion effect of the solid abrasive, the shearing effect of the water on the material, and the micro - machining effect of the abrasive on the cutting surface.

[0031] The waste water generated during the cutting of the blade A by the water knife cutting head 320 will fall onto the water receiving tray 210 located below the water knife cutting head 320, and the water receiving tray 210 will then converge the waste water into the waste water tank 220, thereby realizing the collection of the waste water.

[0032] The blade cutting device disclosed in the embodiments of the present application, by setting the water receiving tray 210 and the waste water tank 220, makes the water receiving tray 210 located below the water knife cutting head 320, so that the waste water generated when the water knife cutting head 320 cuts the blade A can be collected in the waste water tank through the water receiving tray 210, thereby avoiding the waste water generated during the cutting of the blade A by the water knife cutting head 320 from polluting the environment.

[0033] When the water receiving tray 210 collects waste water, it not only collects the waste water generated during the cutting of the blade A by the water jet cutting head 320, but also collects the waste materials generated by cutting the blade A. If the waste water and waste materials are directly discharged into the waste water tank 220, it is easy to cause blockage of the pipeline. Optionally, the waste water collection module 200 may further include a sedimentation tank 230 and a water pump 240. The sedimentation tank 230 may be provided on the equipment frame 100, and the water receiving tray 210, the sedimentation tank 230, the water pump 240, and the waste water tank 220 may be connected in sequence. The sedimentation tank 230 may be a device for separating waste water and waste materials.

[0034] The blade cutting equipment disclosed in the embodiment of the present application is provided with a sedimentation tank 230 and a water pump 240, so that the water receiving tray 210, the sedimentation tank 230, the water pump 240, and the waste water tank 220 can be connected in sequence, so that the waste water and waste materials collected by the water receiving tray 210 enter the sedimentation tank 230 together. After the waste water and waste materials are separated in the sedimentation tank 230, the water pump 240 pumps the waste water in the sedimentation tank 230 into the waste water tank. The waste materials separated in the sedimentation tank 230 can be processed regularly, so as to alleviate the blockage of the pipeline caused by the waste materials, and the waste materials entering the water pump 240 can be reduced, thereby protecting the water pump.

[0035] In an alternative embodiment, the waste water collection module 200 may further include a first filtering device 250, and the first filtering device 250 may be provided between the sedimentation tank 230 and the water pump 240. The first filtering device 250 can filter out waste materials with larger volumes. The first filtering device 250 may be a filter screen, filter cotton, etc. The embodiment of the present application does not make specific limitations on the selection of the first filtering device 250.

[0036] The blade cutting equipment disclosed in the embodiment of the present application is provided with a first filtering device 250 between the sedimentation tank 230 and the water pump 240, so that the first filtering device 250 can filter out waste materials with larger volumes, thereby preventing waste materials with larger volumes from entering the water pump 240, and thus protecting the water pump 240.

[0037] Optionally, the water receiving tray 210 may be provided with an avoidance hole, and the cutting head driving module 310 may pass through the avoidance hole and be provided on the equipment frame 100. The projected area of the water receiving tray 210 in the vertical direction may be greater than or equal to the projected area of the movement range of the water jet cutting head 320 in the vertical direction.

[0038] The blade cutting equipment disclosed in the embodiment of the present application sets the projected area of the water receiving tray 210 in the vertical direction to be greater than or equal to the projected area of the movement range of the water jet cutting head 320 in the vertical direction, so as to collect the waste water generated within the entire movement range of the water jet cutting head 320.

[0039] Specifically, the water receiving tray 210 can be funnel-shaped, so that the waste water can be converged to the central area and then flow into the waste water tank 220 or the sedimentation tank 230, thereby avoiding the waste water flowing out from the edge of the water receiving tray 210.

[0040] Of course, the water receiving tray 210 can also be a disc-shaped structure or other structures, and the embodiment of the present application does not specifically limit the structure of the water receiving tray 210.

[0041] In another embodiment, the waste water collection module 200 may further include a first driving mechanism. The first driving mechanism can be arranged on the equipment frame 100 and connected to the water receiving tray 210. The first driving mechanism can drive the water receiving tray 210 to move according to the movement path of the water knife cutting head 320, so that the projection of the water knife cutting head 320 in the vertical direction is always located within the projection of the water receiving tray 210 in the vertical direction. The projected area of the water receiving tray 210 in the vertical direction is smaller than the projected area of the movement range of the water knife cutting head 320 in the vertical direction.

[0042] In the embodiment of the present application, the blade cutting equipment disclosed by setting the first driving mechanism, so that the first driving mechanism is connected to the water receiving tray 210, so that the first driving mechanism can drive the water receiving tray 210 to move according to the movement path of the water knife cutting head 320, so that the projection of the water knife cutting head 320 in the vertical direction is always located within the projection of the water receiving tray 210 in the vertical direction, and further the water receiving tray 210 can be set relatively small, which is beneficial to the miniaturized design of the waste water collection module 200.

[0043] Optionally, the blade cutting equipment may further include a second filtering device 400. The second filtering device 400 can be arranged on the equipment frame 100 and located above the water receiving tray 210. The second filtering device 400 can be used to filter the waste materials of the blade A generated during the cutting of the blade A by the water knife cutting head 320, so as to reduce the waste materials falling on the water receiving tray 210, and further alleviate the problem of the waste materials entering the pipeline below the water receiving tray 210 and causing blockage of the pipeline.

[0044] Specifically, the second filtering device 400 can be a filter screen, filter cotton, etc.

[0045] Optionally, the second filtering device 400 may include a filtering bracket 410, a second driving mechanism 420, and a plurality of conveying rollers 430. The plurality of conveying rollers 430 may be arranged at intervals in sequence and rotatably disposed on the filtering bracket 410. The rotation axes of the plurality of conveying rollers 430 are parallel, and the gaps between the plurality of conveying rollers 430 can be used for the waste water generated during the cutting of the blade A by the water jet cutting head 320 to flow into the water receiving tray 210. The second driving mechanism 420 can be connected to the plurality of conveying rollers 430 and is used to drive the plurality of conveying rollers 430 to rotate, so that the plurality of conveying rollers 430 convey the waste material of the blade A generated during the cutting of the blade A by the water jet cutting head 320 outside the blade cutting device.

[0046] In the blade cutting device disclosed in the embodiment of the present application, by setting the second filtering device 400 to include a filtering bracket 410, a second driving mechanism 420, and a plurality of conveying rollers 430, the gaps between the plurality of conveying rollers 430 allow the waste water generated during the cutting of the blade A by the water jet cutting head 320 to flow into the water receiving tray 210. The second driving mechanism 420 drives the plurality of conveying rollers 430 to rotate, so that the plurality of conveying rollers 430 convey the waste material of the blade A generated during the cutting of the blade A by the water jet cutting head 320 outside the blade cutting device, thereby avoiding the accumulation of waste material on the plurality of conveying rollers 430, and further facilitating the smooth flow of waste water into the water receiving tray 210.

[0047] In an alternative embodiment, the cutting head driving module 310 may include an omnidirectional moving robotic arm 311 and a lifting mechanism 312. The lifting mechanism 312 may be disposed on the equipment frame 100. The lifting mechanism 312 may be connected to the omnidirectional moving robotic arm 311 and is used to drive the omnidirectional moving robotic arm 311 to lift. The omnidirectional moving robotic arm 311 may be connected to the water jet cutting head 320.

[0048] The omnidirectional moving robotic arm 311 refers to a robotic arm that can move freely in any direction. It can move forward, backward, left, and right, and even rotate in the horizontal direction without changing its own orientation. By setting the cutting head driving module 310 to include an omnidirectional moving robotic arm 311 and a lifting mechanism 312, the movement of the cutting head driving module 310 to drive the water jet cutting head 320 becomes more flexible.

[0049] Since the blade A is relatively large in volume, the wind direction and wind force of the environment will affect the stability of the blade cutting device for the blade A. Optionally, the blade cutting device may further include a weather instrument 500. The weather instrument 500 may be disposed on the equipment frame 100 and can be used to detect the wind direction and wind force of the environment where the blade cutting device is located, so as to detect the wind direction and wind force of the environment in real time. Furthermore, when the wind direction and wind force of the environment have a great impact on the blade A disposed on the blade cutting device, relevant operations can be stopped immediately.
