Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology, and in particular to a feeding rack for an automatic balancing machine for cross-flow fan impellers. Background Technology

[0002] During the processing of cross-flow impellers, multiple impellers are arranged sequentially and temporarily stored on a material rack. A lifting device then lifts the impellers from the rack one by one and transfers them to the next workstation. However, during this process, due to an unreasonable design of the material distribution and blocking device, another impeller located next to it is easily lifted simultaneously or falls after being lifted, causing damage to the impeller or causing it to pile up on top of other impellers, thus affecting the normal operation of subsequent equipment.

The two support plates are spaced apart in the left-to-right direction, and the support plates are simultaneously slidably connected to the two connecting rods in the left-to-right direction.

[0010] According to some embodiments of the present invention, at least one of the connecting rods is fixedly connected to both ends with an adjusting seat. The adjusting seat is provided with an elongated through hole extending in the vertical direction. The temporary storage platform also includes a bolt. The bolt can pass through the elongated through hole and be threadedly connected to the frame, so that the adjusting seat is fixed relative to the frame. The bolt can move relative to the adjusting seat along the extension direction of the elongated through hole to adjust the inclination of the support plate.

[0011] According to some embodiments of the present invention, a guide plate is provided on the side of the support plate away from the other support plate, and a guide rod is provided on the guide plate, the guide rod extending in the front-back direction.

[0012] According to some embodiments of the present invention, the lifting component includes a drive shaft, a lifting motor, and two transmission belt assemblies spaced apart in the left-right direction. Each transmission belt assembly includes a drive wheel, a driven wheel, and a belt. The drive wheel and the driven wheel are rotatably connected to the frame. The belt is simultaneously fitted onto the drive wheel and the driven wheel. The left and right ends of the drive shaft are respectively fixedly connected to the drive wheels of the two transmission belt assemblies. The lifting motor is used to drive the drive shaft to rotate. The translation component is fixedly connected to the belt.

[0013] According to some embodiments of the present invention, there are two translation components and two lifting frames. The two translation components are respectively connected to the two lifting frames. The two translation components are slidably connected to the frame in the vertical direction and are respectively fixedly connected to the belts of the two conveyor belt assemblies. The two lifting frames are spaced apart in the horizontal direction, and the temporary storage platform is located between the two lifting frames.

[0014] According to some embodiments of the present invention, the translation component includes a translation base, a slide block, and a translation cylinder. The translation base is slidably connected to the frame in the vertical direction and fixedly connected to the belt. The slide block is slidably connected to the translation base in the front-back direction. The translation cylinder is installed on the translation base and is used to drive the slide block to move in the front-back direction. The lifting frame is fixedly installed on the slide block.

[0015] According to some embodiments of the present invention, at least one of the translation components includes a first seat and a second seat. The first seat is slidably connected to the frame in the vertical direction and fixedly connected to the belt. The slide is slidably connected to the second seat in the front-back direction.

[0018] 1. When it is necessary to transfer the impeller on the temporary storage platform to the next work station, the lifting component drives the translation component and the lifting frame to move vertically to below the temporary storage platform. The translation component drives the lifting frame to move backward to directly below the impeller at the front of the temporary storage platform. The lifting component then drives the lifting frame to move upward, so that the lifting frame lifts the impeller at the front of the temporary storage platform, causing the impeller to fall onto the lifting frame and be supported and positioned by the two inclined plates. At the same time, the partition plate is inserted upward between the front impeller and the next impeller. While the front impeller is being lifted upward, the next impeller is blocked by the partition plate and cannot move forward, thus preventing the next impeller from being lifted upward as well.

[0019] 2. Operators can easily adjust the height of one end of the connecting rod, thereby changing the tilt angle of the entire temporary storage platform, achieving stable and orderly gravity conveying, and ensuring the stability and safety of the entire feeding process.

[0039] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0040] According to some embodiments of this utility model, refer to Figures 1 to 6 The automatic balancing rack for cross-flow fan turbines includes a frame 100, a temporary storage platform 200, and a transfer device 300. The temporary storage platform 200 is mounted on the frame 100. Multiple fan turbines 310 are arranged sequentially along the front-to-back direction on the temporary storage platform 200. A baffle plate 210 is provided at the front end of the temporary storage platform 200. The baffle plate 210 tilts upwards from back to front, while the temporary storage platform 200 tilts downwards from back to front, allowing the fan turbines 310 to roll forward on the temporary storage platform 200 under the influence of gravity. The baffle plate 210 is used to prevent the fan turbines 310 from continuing to roll forward and to prevent them from rolling off the temporary storage platform 200. The transfer device 300 includes a lifting component 400, a translation component 500, and a lifting frame 600. The lifting frame 600 includes a partition plate 610 and two inclined plates 620 symmetrically arranged in the front-to-back direction. The inclined plates 620 are inclined from bottom to top away from the other inclined plate 620, i.e., the two inclined plates 620 cooperate to form a V-shape, so that the impeller 310 located on the lifting frame 600 can automatically center itself under the action of gravity. The upper end of the inclined plate 620 located on the rear side is connected to the upper end of the partition plate 610, which is vertically arranged. The translation component 500 can drive the lifting frame 600 to move in the front-to-back direction, and the lifting component 400 can drive the translation component 500 and the lifting frame 600 to move in the up-down direction. The lifting frame 600 can move upward to lift the impeller 310 located at the foremost side of the temporary storage platform 200, and the partition plate 610 is inserted upward between the foremost impeller 310 and the next impeller 310.

[0041] Understandably, when it is necessary to transfer the impeller 310 on the temporary storage platform 200 to the next workstation, the lifting component 400 drives the translation component 500 and the lifting frame 600 to move vertically below the temporary storage platform 200. Then, the translation component 500 drives the lifting frame 600 to move backward, so that the lifting frame 600 is directly below the impeller 310 at the front of the temporary storage platform 200. The lifting component 400 then drives the lifting frame 600 upward, so that the lifting frame 600 lifts the impeller 310 at the front of the temporary storage platform 200. Because the temporary storage platform 200 and the lifting frame 600 are staggered horizontally, the lifting frame 600 avoids collision and interference with the temporary storage platform 200 when lifting the impeller 310. (Refer to...) Figure 3 and Figure 4 The lifting frame 600 lifts the impeller 310 upwards, causing the impeller 310 to fall onto the lifting frame 600 and be supported and positioned by the two inclined plates 620. At the same time, the partition plate 610 is inserted upwards between the foremost impeller 310 and the next impeller 310. While the foremost impeller 310 is being lifted upwards, the next impeller 310 is blocked by the partition plate 610 and cannot move forward, thus preventing the next impeller 310 from being lifted upwards as well.

[0042] Preferably, there are multiple temporary storage stations 200, which are spaced apart in the vertical direction. Each temporary storage platform 200 can temporarily store multiple impellers 310. The cooperation of multiple temporary storage platforms 200 can increase the number of impellers 310 that can be temporarily stored. When it is necessary to transfer the foremost impeller 310 of one of the temporary storage platforms 200, the lifting component 400 drives the lifting frame 600 to move vertically to the gap between the temporary storage platform 200 and the next layer of temporary storage platforms 200. The translation component 500 then drives the lifting frame 600 to move backward, so that the lifting frame 600 moves to directly below the foremost impeller 310 of the temporary storage platform 200. The lifting component 400 then drives the lifting frame 600 to move upward to lift the impeller 310, so that the impeller 310 is lifted to the gap between the temporary storage platform 200 and the next layer of temporary storage platforms 200. The translation component 500 then drives the lifting frame 600 and the impeller 310 to move forward, and moves the impeller 310 to the next work station.

[0043] According to some embodiments of this utility model, refer to Figure 2 The temporary storage platform 200 includes two connecting rods 220 and two support plates 230. The two connecting rods 220 are spaced apart in the front-to-back direction, and their axes are oriented left-to-right. Both ends of the connecting rods 220 are mounted on the frame 100. The two support plates 230 are spaced apart in the left-to-right direction and are slidably connected to the two connecting rods 220 in the left-to-right direction. The two connecting rods 220 work together to support the support plates 230. The support plates 230 can slide on the connecting rods 220 in the left-to-right direction, thereby adjusting the distance between the two support plates 230 to accommodate wind turbines 310 of various lengths and improve versatility.

[0044] Preferably, the support plate 230 is provided with an adjustment mechanism, and the connecting rod 220 passes through the adjustment mechanism. The adjustment mechanism is provided with a cam handle. Rotating the cam handle can fix the support plate 230 and the connecting rod 220 relative to each other. Rotating the cam handle again can allow the support plate 230 to slide relative to the connecting rod 220. The eccentric principle of the cam can be used to generate a strong clamping force to firmly lock the support plate 230 onto the connecting rod 220. Reverse rotation can quickly loosen it, which is convenient and effortless. Alternatively, the support plate 230 and the connecting rod 220 can be fixed relative to each other with bolts. Loosening the bolts can allow the support plate 230 to slide relative to the connecting rod 220.

[0045] It is understandable that impellers 310 of different diameters, weights, or surface materials will exhibit different rolling characteristics at the same tilt angle. An excessively large angle may cause the impeller 310 to roll too fast, generating excessive impact force when it hits the baffle plate 210, potentially damaging the impeller 310 or the baffle plate 210. An excessively small angle may result in poor rolling or even jamming, affecting automatic positioning. By incorporating an adjusting seat 240 with a long through-hole 241, operators can easily adjust the height of one end of the connecting rod 220, thereby changing the tilt angle of the entire temporary storage platform 200. This ensures the optimal tilt angle that guarantees reliable rolling while avoiding impact damage. This achieves smooth and orderly gravity conveying, guaranteeing the stability and safety of the entire feeding process.

[0046] According to some embodiments of this utility model, refer to Figure 6 At least one connecting rod 220 has an adjusting seat 240 fixedly connected to both ends. The adjusting seat 240 has an elongated through hole 241 extending in the vertical direction. The temporary storage platform 200 also includes bolts that can pass through the elongated through hole 241 and be threadedly connected to the frame 100, so that the adjusting seat 240 is relatively fixed to the frame 100. The bolts can move relative to the adjusting seat 240 along the extension direction of the elongated through hole 241 to adjust the inclination of the support plate 230. When it is necessary to adjust the inclination of the support plate 230, the bolts are loosened. At this time, one end of the bolts is still inserted into the frame 100. The adjusting seat 240 can then move in the vertical direction, thereby driving the support rod to move in the vertical direction, so that the bolts move in the vertical direction relative to the adjusting seat 240 within the elongated through hole 241. After the adjusting seat 240 has moved to the specified height, the bolts are tightened to fix the adjusting seat 240 and the frame 100 relatively, thereby completing the adjustment of the inclination of the support plate 230.

[0047] According to some embodiments of this utility model, refer to Figure 2 A guide plate 250 is provided on the side of the support plate 230 away from the other support plate 230. A guide rod 260 is provided on the guide plate 250, and the guide rod 260 extends in the front-back direction. The guide rod 260 plays a limiting role. The guide rods 260 on the two support plates 230 can abut against the left and right ends of the wind turbine 310 respectively. The two guide rods 260 work together to prevent the wind turbine 310 from deviating to the left or right during the front-back movement.

[0048] Preferably, the guide rod 260 is slidably connected to the guide plate 250 in the vertical direction. The guide plate 250 has a through hole extending in the vertical direction. The bolt passes through the through hole and is connected to both the guide plate 250 and the guide rod 260, thereby fixing the guide plate 250 and the guide rod 260 relatively. Tightening the bolt can adjust the height of the guide rod 260 to accommodate various sizes of impellers 310.

[0049] According to some embodiments of this utility model, refer to Figure 1 and Figure 5 The lifting component 400 includes a drive shaft 410, a lifting motor 420, and two transmission belt assemblies 430 spaced apart in the left-right direction. Each transmission belt assembly 430 includes a drive wheel 431, a driven wheel 432, and a belt 433. Both the drive wheel 431 and the driven wheel 432 are rotatably connected to the frame 100. The belt 433 is fitted onto both the drive wheel 431 and the driven wheel 432. The left and right ends of the drive shaft 410 are fixedly connected to the drive wheels 431 of the two transmission belt assemblies 430, respectively. The lifting motor 420 drives the drive shaft 410 to rotate. The translation component 500 is fixedly connected to the belt 433. When the lifting motor 420 drives the drive shaft 410 to rotate, the drive wheel 431 rotates with the drive shaft 410, thereby driving the belt 433 to rotate. When the belt 433 rotates, it drives the translation component 500 to move in the up-down direction.

[0050] According to some embodiments of this utility model, refer to Figure 2 and Figure 5 There are two translation components 500 and two lifting frames 600. The two translation components 500 are respectively connected to the two lifting frames 600. The two translation components 500 are slidably connected to the frame 100 in the vertical direction and are respectively fixedly connected to the belts 433 of the two conveyor belt assemblies 430. The two lifting frames 600 are spaced apart in the horizontal direction. The temporary storage platform 200 is located between the two lifting frames 600. The two lifting frames 600 can work together to support the impeller 310 located on the temporary storage platform 200.

[0051] According to some embodiments of this utility model, refer to Figure 2 and Figure 5 The translation component 500 includes a translation base 510, a slide 520, and a translation cylinder 530. The translation base 510 is slidably connected to the frame 100 in the vertical direction and fixedly connected to the belt 433. The slide 520 is slidably connected to the translation base 510 in the front-back direction. The translation cylinder 530 is mounted on the translation base 510 and is used to drive the slide 520 to move in the front-back direction. The lifting frame 600 is fixedly mounted on the slide 520. The rotation of the belt 433 can drive the translation base 510 to move in the vertical direction, thereby driving the slide 520 and the lifting frame 600 to move in the vertical direction. The translation cylinder 530 drives the slide 520 to move in the front-back direction, thereby driving the lifting frame 600 to move in the front-back direction.

[0052] According to some embodiments of this utility model, refer to Figure 2 and Figure 5At least one translation component 500 has a translation base 510 including a first base 541 and a second base 542. The first base 541 is slidably connected to the frame 100 in the vertical direction and fixedly connected to the belt 433. A slide 520 is slidably connected to the second base 542 in the front-back direction, and the second base 542 is slidably connected to the first base 541 in the left-right direction. The second base 542 can slide in the left-right direction to move the two lifting frames 600 closer to or further apart in the left-right direction. When the two support plates 230 move relative to each other in the left-right direction to adjust the spacing, the movement of the second base 542 relative to the first base 541 can also cause the slides 520 of the two translation components 500 to move relative to each other in the left-right direction, thereby causing the two lifting frames 600 to move relative to each other in the left-right direction to adjust the spacing, accommodating impellers 310 of various lengths.

[0053] According to some embodiments of this utility model, refer to Figure 2 and Figure 5 The translation component 500 also includes a pushing cylinder 550, which is mounted on the slide 520. The pushing cylinders 550 of the two translation components 500 are arranged opposite each other in the left-right direction, and the two pushing cylinders 550 can work together to push the impeller 310 in the left-right direction. When the impeller 310 is located on the two lifting frames 600, the pushing cylinder 550 of the translation component 500 on the left can push the impeller 310 to the right, and the pushing cylinder 550 of the translation component 500 on the right can push the impeller 310 to the left, thereby completing the positioning of the impeller 310. Alternatively, only one of the translation components 500 has a pushing cylinder 550, and the other translation component 500 has a baffle. The pushing cylinder 550 pushes the impeller 310 in the left-right direction, so that the other end of the impeller 310 abuts against the baffle of the other translation component 500, thereby completing the positioning of the impeller 310.

[0054] Understandably, by adding two opposing pushing cylinders 550, the impeller 310 can be actively clamped and centered after being lifted. The two pushing cylinders 550 extend simultaneously, pushing the impeller 310 from both sides with equal force, precisely pushing it to the center of the line connecting the two lifting frames 600. This not only compensates for potential errors in passive positioning but also applies a certain clamping force to the impeller 310 during transfer, further preventing lateral slippage during rapid movement. This improves the final positioning accuracy and reliability of the feeding process.

[0055] The workflow of this embodiment includes:

[0056] First, loosen the support plate 230 of the temporary storage platform 200 by rotating the cam handle, slide it along the connecting rod 220 to a suitable distance, and then rotate the handle again to lock it. Simultaneously, loosen the locking mechanism on the translation base 510, manually slide the second seat 542, and adjust the distance between the two lifting frames 600 to match the distance of the support plate 230. Loosen the bolts on the adjusting seat 240, move the adjusting seat 240 up and down to set the inclination of the temporary storage platform 200, ensuring that the impeller 310 can roll forward at a suitable speed, and finally tighten the bolts to secure it. Then, place multiple impellers 310 on the support plate 230 of the multi-layer temporary storage platform 200. Under the constraint of the guide rods 260 of the two support plates 230, the impellers 310 roll forward along the inclined temporary storage platform 200 due to gravity. Finally, the first impeller 310 is stopped by the front baffle plate 210 and is in a ready-to-grab position, with the remaining impellers 310 arranged sequentially behind it.

[0057] When the control system receives the feeding instruction, the transfer device 300 starts to work.

[0058] The lifting motor starts, driving the two translation components 500 vertically along the guide rails of the frame 100 via the drive shaft 410 and two synchronous conveyor belt assemblies 430, precisely moving them to the preset height between the target temporary storage platform 200 and its next-level temporary storage platform 200. Simultaneously, the translation cylinders 530 on the two translation components 500 actuate, driving the slide block 520 and the fixed lifting frame 600 to move backward along the guide rails in the front-rear direction, so that the two lifting frames 600 are precisely positioned directly below the first impeller 310 on the temporary storage platform 200. The lifting motor then rotates in the opposite direction, lifting the translation components 500 upward. During this process, the V-shaped inclined plate 620 on the lifting frame 600 contacts and lifts the impeller 310. Simultaneously, the isolation plate 610 located above the rear inclined plate 620 precisely inserts upward into the gap between the lifted first impeller 310 and the immediately following second impeller 310, preventing the second impeller 310 from moving forward.

[0059] The impeller 310 is completely lifted off the temporary storage platform 200 and falls stably into the V-shaped grooves of the two lifting frames 600 under gravity, achieving initial passive centering. Next, two pushing cylinders 550 mounted on the slide 520 extend towards each other, gently pushing the impeller 310 from both sides for a second, high-precision active centering, and can apply a slight clamping force during the movement. The translation cylinder 530 then reverses its action, driving the slide 520 and the lifting frames 600 forward, completely removing the lifting frame 600 carrying the impeller 310 from the temporary storage platform 200 area and moving it to the transfer position at the front of the equipment.

[0060] The lifting component 400 can be adjusted again according to the height requirements of the next workstation to transport the impeller 310 to the designated handover height. After the impeller 310 is received by the next workstation, the lifting frame 600 of the transfer device 300 returns to the initial standby position in reverse order or moves directly to the next material picking level, ready to execute the next material picking cycle. At the same time, on the temporary storage platform 200, since the first impeller 310 has been removed, the second impeller 310, which was originally blocked by the isolation plate 610, automatically rolls forward under the action of gravity until it is stopped by the baffle plate 210, becoming the new object to be grabbed. The entire system realizes continuous and fully automatic material feeding operation.
