Description

[0002] There are many kinds of drying equipment at present, among which hollow paddle dryer is getting more and more attention from all parties due to its high thermal efficiency. However, it is difficult to manufacture the hollow paddle shaft in the hollow paddle dryer. Although the diameter of the paddle shaft is not small, from the perspective of aspect ratio, the paddle shaft is a slender shaft, and the processing of slender shaft is difficult to process in the industry. In addition, when the wedge-shaped hollow paddle is welded to the hollow shaft, it will also cause serious deformation of the hollow shaft, and even cracking will occur, which seriously affects the manufacturing quality of the hollow paddle shaft.

[0003] In addition, the traditional manufacturing method of wedge-shaped hollow blades is through welding of sheet materials, and the welded sheets are pre-cut. Since the hollow blades are wedge-shaped and hollow, there are many types of sheets used for welding. It is also difficult to straighten the sheets during welding, so the welding quality cannot be guaranteed. Air leakage often occurs during use, which seriously affects the normal operation of the equipment. Therefore, after the production of the hollow blades is completed, the welding quality needs to be tested.

[0047] See also Figure 1-12 The present invention provides a technical solution: a component detection system of a blade dryer and a working method thereof, comprising a transmission component 6, a sealing component and an inflation component,

[0048] The transmission assembly 6 includes a pair of transmission guide rails 601, which are connected end to end. The upper side of the transmission guide rails 601 is slidably matched with a plurality of support seats 602, which support the two ends of the shaft of the hollow blade 7, and there is a same distance difference between the plurality of hollow blades 7;

[0049] The closed assembly includes a pair of closed side plates 1, a groove is provided at the center of the upper end of the closed side plate 1, and the groove is adapted to the shaft diameter of the hollow blade 7. A plurality of guide pillars 101 are fixedly connected to both ends of the closed side plate 1, and a guide sleeve 102 is slidably matched at the lower end of the guide pillar 101, and a base 8 is fixedly connected to the lower end of the guide sleeve 102. In the initial state, the lower end of the guide pillar 101 is in contact with the base 8, and the lowermost end of the shaft of the hollow blade 7 on the support seat 602 is higher than the upper end surface of the closed side plate 1;

[0050] The upper ends of the base 8 are fixedly connected with side plates 801 on both sides, the upper ends of the side plates 801 are fixedly connected with the top plates 802, and the lower ends of the top plates 802 are fixedly connected with the upper closed cavity 103. The upper closed cavity 103 is semi-cylindrical, and grooves are provided at the lower sides of both ends. When the closed side plates 1 and the upper closed cavity 103 are combined with each other, the hollow blades 7 are clamped by the grooves.

[0051] The transmission guide rail 601 passes through the inner side of the side plate 801 and is fixedly connected thereto;

[0052] A liftable closed lower arc plate 104 is provided at the lower end of the closed side plate 1, and the guide column 101 penetrates the closed lower arc plate 104 and slides with it. When the closed lower arc plate 104, the closed side plate 1 and the upper closed cavity 103 are combined with each other, a closed space is formed outside the hollow blade 7, and both ends of the shaft of the hollow blade 7 extend outside the closed space.

[0053] The inflatable component is disposed at the lower end of the closed lower arc plate 104, and the inflatable component is used to inflate air into the closed space.

[0054] First, the hollow blade 7 is supported by the support seat 602 and transported along the transmission guide rail 601. The hollow blade 7 moves to the upper side of the closed side plate 1, corresponding to the position of the groove. Since the lower end of the shaft of the hollow blade 7 on the support seat 602 is higher than the upper end surface of the closed side plate 1, the hollow blade 7 does not contact the closed side plate 1 at this time; then the closed lower arc plate 104 moves upward, first contacts the closed side plate 1 and pushes it upward, and the closed side plate 1 moves upward so that the groove receives the hollow blade 7 and brings it up until the closed side plate 1 is closed. The side plate 1 is connected to the upper closed cavity 103, and the upper and lower grooves clamp the two ends of the shaft of the hollow blade 7, so as to form a closed space outside the hollow blade 7; then, the closed space is inflated through the inflation assembly. Since the two ends of the shaft extend outside the closed space, if the weld of the hollow blade 7 leaks, the inflated gas will pass through the weld and blow out from the two ends of the shaft. By observing whether the two ends of the shaft of the hollow blade 7 leak, it can be judged whether the air tightness of the hollow blade 7 is qualified, that is, whether the welding quality is qualified. The detection result is intuitive and clear, and it is highly practical.

[0055] After the detection is completed, the closed lower arc plate 104 drives the hollow blade 7 to reset, so that it falls back onto the support seat 602, and then continues to be transmitted to the subsequent process, realizing the function of automatic transportation and detection of the hollow blade 7, without manual intervention in the whole process, and the detection efficiency is high;

[0056] Preferably, a rubber strip may be provided at the joints of the closed side plate 1, the upper closed cavity 103 and the closed lower arc plate 104, so as to further improve the airtightness.

[0057] The center of the base 8 is fixedly connected to a motor part, the upper end of the motor part drives a threaded column 4, the upper end of the threaded column 4 is threadedly connected to a threaded tube 401, the lower end center of the closed lower arc plate 104 is fixedly connected to a fixing seat 105, and the threaded tube 401 is connected to the fixing seat 105.

[0058] Preferably, when the closed lower arc plate 104 needs to be driven to move, the threaded column 4 is driven to rotate by the motor, the threaded column 4 is threadedly connected to the threaded tube 401, and because the guide column 101 and the closed lower arc plate 104 slide together, the closed lower arc plate 104 is raised and lowered under the guidance of the guide column 101.

[0059] The inflation component includes a pair of cylindrical cavities 3, which are arranged on both sides of the threaded column 4. The upper ends of the cylindrical cavities 3 are fixedly connected to the closed lower arc plate 104 and are internally communicated. The inner side of the cylindrical cavity 3 is slidably fitted with a piston disk 301, and the lower end of the piston disk 301 is fixedly connected with a piston rod 302. The piston rod 302 passes through the lower end of the cylindrical cavity 3 and is gap-fitted with it. A laser ranging sensor is arranged inside the cylindrical cavity 3, and the laser ranging sensor is used to detect the displacement distance of the piston disk 301.

[0060] Preferably, when it is necessary to inflate the closed space, the piston disc 301 is driven to move by the piston rod 302, and the piston disc 301 is displaced upward in the cylindrical cavity 3. If the air tightness of the hollow blade 7 is intact at this time, the inside of the closed space cannot be blown in due to the presence of gas, and the pressure inside and outside is the same, that is, the piston disc 301 cannot rise. On the contrary, if there is a leak, the piston disc 301 can continue to rise, and whether the welding quality is intact can be detected. Further, a laser ranging sensor is used to detect the displacement of the piston disc 301. Specifically, a laser emitting end is set at the lower end of the inner part of the cylindrical cavity 3, and a receiving end is correspondingly set at the lower end of the piston disc 301, so that the distance between the two is detected, which is more convenient. Since the laser ranging sensor is a prior art, it will not be described in detail here.

[0061] A sprocket 1 303 is provided on the outer side of the middle side of the threaded tube 401, an external thread is provided on the outer side of the piston rod 302, a sprocket 2 304 is connected to the outer thread of the piston rod 302, the upper end of the sprocket 2 304 is rotatably connected to the cylindrical cavity 3, and the sprocket 1 303 and the sprockets 2 304 on both sides are connected by chain transmission.

[0062] Preferably, a plurality of guiding telescopic rods are arranged at the lower end of the cylindrical cavity 3, and a guide plate is arranged at the lower end of the guiding telescopic rod, and the guide plate is fixedly connected to the piston rod 302, so as to guide the displacement of the piston rod 302 and the piston disk 301. Specifically, a sprocket 1 303 is arranged, which drives the sprocket 2 304 on both sides to rotate synchronously through chain transmission, and the sprocket 2 304 drives the piston rod 302 to move through a threaded connection, so that the piston disks 301 on both sides can be displaced synchronously.

[0063] The threaded tube 401 is fixedly connected to the sprocket wheel 303, the upper end of the threaded tube 401 is rotatably connected to the fixed seat 105, straight key grooves are provided on both sides of the upper end of the threaded tube 401, and a driving key 305 is slidably matched inside the straight key groove, and a collar 306 is fixedly connected to the outer end of the driving key 305, and a plurality of clamping columns 307 are fixedly connected to the upper end of the collar 306, and a plurality of cylindrical grooves 308 are provided at the lower end of the fixed seat 105, and the cylindrical grooves 308 are adapted to the clamping columns 307, and the cylindrical grooves 308 are evenly distributed in an annular shape;

[0064] The outer side of the collar 306 is rotatably connected to the support plate 2 , and a plurality of spring retractable rods are arranged between the support plate 2 and the fixing seat 105 .

[0065] Preferably, a spring retracting rod is provided. In the initial state, the support plate 2 and the fixing seat 105 are close to each other, so that the clamping column 307 on the upper side of the collar 306 is clamped into the cylindrical groove 308, so that the collar 306 and the fixing seat 105 are locked with each other, and the collar 306 is fixed. Through the straight key groove and the driving key 305, the threaded tube 401 is controlled to be fixed. At this time, the threaded column 4 rotates to drive the closed lower arc plate 104 to move upward until a closed space is formed. At this time, the support plate 2 drives the collar 306 to move downward , the clamping column 307 is away from the cylindrical groove 308, and the stuck state of the two is released. At this time, if the threaded column 4 continues to rotate, the threaded column 4 drives the threaded tube 401 to rotate synchronously relative to the fixed seat 105, and the closed lower arc plate 104 maintains the current height unchanged, and the threaded tube 401 can drive the sprocket 303 to rotate, so that the piston disk 301 is displaced for inflation detection, and the inflation test is directly carried out after the closed space is realized. The two are connected smoothly, and the degree of automation is high, and it can be realized by only rotating a single threaded column 4, saving costs;

[0066] When the detection is completed, the threaded column 4 reverses. If the hollow blade 7 leaks, the piston disc 301 is driven to move downward (if there is no leakage, the piston disc 301 itself cannot move) until it contacts the bottom of the cylindrical cavity 3, so that the piston disc 301 cannot move further, and the sprocket wheel 2 304 cannot rotate, resulting in the sprocket wheel 1 303 and the threaded tube 401 being unable to rotate. At this time, the threaded column 4 reverses to drive the closed lower arc plate 104 to reset, with a high degree of automation.

[0067] A square groove 106 is provided at the upper end of the fixing seat 105, a strip block 107 is provided on the upper side of the square groove 106, a pair of guide rods 108 are fixedly connected to the lower end of the strip block 107, the guide rods 108 penetrate the fixing seat 105 and slide with it, and a square groove 106 is provided at the lower end of the fixing seat 105, a strip block 2 109 is fixedly connected to the lower end of the guide rod 108, and the square groove 106 is adapted to the strip block 107 or the strip block 2 109;

[0068] The upper end surface of the fixing seat 105 is flush with the upper end surface of the closed lower arc plate 104 , and the two ends of the upper closed cavity 103 are fixedly connected with a pressing platform 110 , which corresponds to the strip block 107 .

[0069] Preferably, when the support plate 2 needs to be driven to drive the collar 306 to move downward, a strip block 107 is provided. Specifically, in the above embodiment, the spring retracting rod makes the support plate 2 and the fixing seat 105 close to each other, and the support plate 2 lifts the strip block 109 into the lower square groove 106, so that the strip block 107 is higher than the upper square groove 106 (such as Fig. 9 As shown), at this time, the threaded column 4 drives the closed lower arc plate 104 to rise, and when a closed space is formed, the strip block 107 contacts the pressing platform 110 until the pressing platform 110 presses the strip block 107 down, and the strip block 107 pushes the guide rod 108 and the strip block 2 109 downward to press the support plate 2 downward, so that the clamping column 307 is away from the cylindrical groove 308, so that the stuck state of the ring 306 is released when the closed space is formed, and the inflation test can be carried out. That is to say, by setting the strip block 107 and the strip block 2 109, the stuck state of the ring 306 and the fixing seat 105 can be automatically released, without the need for additional drive components or control programs, saving costs;

[0070] When the closed lower arc plate 104 is lowered and reset, the upper end surface of the fixing seat 105 is away from the pressing platform 110, and the support plate 2 can be raised and reset, so that the clamping column 307 is locked with the cylindrical groove 308 again, preparing for the next work.

[0071] A driving rubber wheel 202 is provided at the lower end of the transmission guide rail 601, and the driving rubber wheel 202 is in close contact with the support seat 602. The driving rubber wheel 202 is used to drive the support seat 602 for transportation. The inner side of the side plate 801 is rotatably connected to a center rod 203, and the center rod 203 is fixedly connected to the driving rubber wheel 202.

[0072] Preferably, when the hollow blade 7 needs to be driven for transportation, the rubber wheel 202 is driven to rotate, and the support seat 602 is driven to move along the transmission guide rail 601 through friction. Several support seats 602 push each other and the transmission guide rails 601 are connected end to end to form a closed transportation line, which can drive the support seat 602 for circular transportation.

[0073] A pair of spring contraction columns 201 are provided at the lower end of the transmission guide rail 601, and a lifting plate 204 is connected to the lower end of the spring contraction column 201. A rack 205 is fixedly connected to one end of the lifting plate 204. A gear 206 is provided at the outer end of the center rod 203. The rack 205 and the gear 206 are meshed with each other. An adaption groove is provided on the inner side of the side plate 801.

[0074] A plurality of recessed grooves are provided at the outer end of the center rod 203, and the center rod 203 passes through the gear 206 and is rotatably connected thereto. An annular groove 207 is provided on one side of the gear 206, and an arc-shaped tooth 208 is clamped on the inner side of the annular groove 207. The arc-shaped tooth 208 is adapted to the recessed groove and a spring telescopic rod is provided between the two.

[0075] Preferably, the rack 205 is driven down by the lifting plate 204, and the rack 205 is meshed with the gear 206, thereby driving the central rod 203 to rotate, thereby driving the driving rubber wheel 202 to rotate, and driving the support seat 602. When the rack 205 drives the gear 206 from top to bottom and the meshing is completed once, the support seat 602 also transports the next hollow blade 7 to the upper side of the closed side plate 1. Since there is the same distance difference between the plurality of hollow blades 7, it can be ensured that after each meshing is completed, the next hollow blade 7 can be transported to the right place, and the two have good synchronization.

[0076] Preferably, when the rack 205 needs to rise and reset, in order to avoid driving the gear 206 to reverse again, an arc-shaped latch tooth 208 and an annular latch groove 207 are provided, and the two restrict each other so that they can only rotate relative to each other in one direction. Specifically, when the rack 205 moves downward, the driving gear 206 rotates against the arc-shaped latch tooth 208, that is, the driving force of the annular latch groove 207 and the arc-shaped latch tooth 208 acts on the straight surface of the arc-shaped latch tooth 208, and the two are locked with each other, so that the gear 206 can move with the center The rod 203 rotates synchronously, so that the support seat 602 can be driven for normal transportation. When the rack 205 needs to rise and reset, the driving force of the annular groove 207 and the arc-shaped tooth 208 acts on the arc surface of the arc-shaped tooth 208. The arc-shaped tooth 208 is forced to retract into the sink groove for avoidance, so that the gear 206 can rotate relative to the center rod 203, and the center rod 203 and the driving rubber wheel 202 remain stationary, thereby realizing intermittent transportation of the hollow blade 7, with a high degree of automation.

[0077] A bearing seat 209 is fixedly connected to the inner side of the lifting plate 204 , and the upper end surface of the bearing seat 209 is matched with the closed lower arc plate 104 .

[0078] Preferably, a bearing seat 209 is provided and matched with the two ends of the closed lower arc plate 104.
