Description

Technical Field

[0001] The present invention relates to the technical field of dryer blades, and particularly to a blade assembly detection device for a dryer. Background Art

[0002] A dryer is a device used to remove moisture from materials and is widely used in industries such as food, chemical, medicine, wood, and textile. The assembly of dryer blades is an important link in the installation and maintenance of dryers. The assembly quality of the blades directly affects the operating efficiency of the dryer, the drying effect of the materials, and the service life of the equipment. Therefore, a blade assembly detection device for a dryer is needed.

[0003] Currently, during the process of assembling the blades, most often manual labor is required to carry the blades to the installation area for placement. Usually, multiple blades need to be installed, and a large amount of manpower is consumed during the assembly process. Moreover, there is a possibility of deviation in the placement position during the placement process. After installation, it will cause an increase in the operating resistance of the equipment, resulting in poor flow of materials in the dryer or uneven drying, and some blades may have defects inside, which are difficult to quickly detect before installation;

[0004] And because the objects are large in size, and the blades usually need to be installed on both sides, it is very difficult to manually flip and position the blades during manual operation. Especially when the blades on one side are installed, it is easy to cause collisions during the flipping process. After flipping to the specified position, it will rotate automatically due to its own weight, which delays the work efficiency;

[0005] After the blades are welded, there may be cases of missed welding or false welding in the welded area. Applying too much force during the detection process will cause the blades to break directly, while applying too little force has no effect and it is difficult to distinguish. For this reason, a blade assembly detection device for a dryer is proposed. Summary of the Invention

If there is a large deviation, it can be processed in time to prevent installation. The front end of the first probe 452 contacts the inner cavity surface of the blade body 61.

[0060] A vertical frame 43 is fixedly installed on one side of the detection table 4, and a driving screw and a guide roller are arranged between the vertical frame 43 and the driving frame 11. The upper frame plate 51 is movably connected to the driving screw and the guide roller to act on the transportation of the blade body 61.

One end of the transmission rod 172 is fixedly installed on the outer surface of the adjustment shaft, and the left and right swing of the transmission rod 172 is controlled according to the rotation of the adjustment shaft. Limit plates can be arranged on the workbench 1 and the operating table 14 to limit and support the transmission rod 172. The other end of the transmission rod 172 acts on the movement of the weight block 171 in a separated manner, and an arc-shaped block is fixed thereon. A rubber strip is installed in the arc-shaped block to increase the friction with the material shaft 6 and prevent self-rotation. A through arc-shaped groove is formed in the arc-shaped block, and the bearing piece 173 is movably connected in the arc-shaped groove to support the material shaft 6. One end of the weight block 171 passes through the arc-shaped groove and is fixed on the bottom surface of the bearing piece 173. The material shaft 6 is placed on the bearing piece 173, and the weight block 171 can always maintain a state perpendicular to the bottom surface, and the position of the material shaft 6 will not shift and always maintain the angle at the time of installation.

[0066] Positioning components 7 are symmetrically installed on both sides of the second guide rail. The positioning component 7 includes a third base plate 71, a positioning frame 72 and a clamping arc piece 73. The positioning frame 72 is vertically installed on the top surface of the third base plate 71, and the clamping arc piece 73 is rotatably connected to the top end of the positioning frame 72. The material shaft 6 is connected in the positioning frame 72 to clamp and position the material shaft 6 to prevent it from moving back and forth when a force is applied during the detection process. A push block 22 is also installed on one side of the third base plate 71.

[0067] A third lead screw is installed on the operating table 14, and the moving frame 141 is threadedly connected to the third lead screw. The detection member 8 includes a support block 81, a rotating shell 82, and a swinging rod 84. The support block 81 is fixedly installed on the top end of the moving frame 141. There are two symmetrically installed rotating shells 82, and the two rotating shells 82 are rotatably connected to both sides of the support block 81. An adjustment knob is arranged on the support block 81 outside the rotating shell 82 to position the angle of the rotating shell 82. An arc-shaped frame 83 is arranged on the bottom side of the rotating shell 82, and the arc-shaped frame 83 is adapted to the radian of the material shaft 6. A plurality of partition blocks 87 are fixedly installed in the arc-shaped frame 83 to limit the detection rotating ball 86 for convenient arbitrary adjustment. A detection rotating ball 86 is rotatably connected between the partition blocks 87, and a second probe 88 is installed in the detection rotating ball 86. Tightening screws are connected to the outside of the detection rotating ball 86, and the tightening screws are arranged on the arc-shaped frame 83. One end of the second probe 88 is connected to the welding joint of the blade body 61 and the material shaft 6. A groove is formed in the support block 81, and an inner ring is arranged in the groove. Swing rods are installed on both sides of the inner ring to manually control the shaking of the welded blade body 61. The swing rods are rotatably connected to the inner wall of the groove. The outer rod surface of the swinging rod 84 is threadedly connected to the inner ring to lift the hoop block 85 up and down. The bottom end of the swinging rod 84 is connected to a hoop block 85, and the hoop block 85 is clamped on the blade body 61.

[0068] Working principle: After completing the detection and installation of the blade body 61, control the first lead screw 24 to rotate again to lower the material shaft 6 until the material shaft 6 is placed on the bearing piece 173. Operate the clamping block 27 to loosen, reverse-rotate the push lead screw to push the rotary lifting assembly 2 and the lifting member 3 backward. After pushing to the specified position, lift the return push rod to remove the insertion block 181 from the push block 22 on the side of the first bottom plate 21. Control the transmission rod 172 to rotate to move the material shaft 6 to one side of the operation table 14 and connect the insertion block 181 to the push block 22 on the side of the third bottom plate 71. Control the push block 22 to move forward to push the positioning assembly 7 forward. After moving to the specified position, close the clamping arc piece 73 to firmly fix the material shaft 6. Then adjust the moving frame 141 to one side of the blade body 61, turn the rotating shell 82 downward and fix it. Then adjust the position of the detection rotating ball 86 to connect the second probe 88 to the welding seam. Then rotate the swing rod 84, and the hoop block 85 will move downward to clamp the blade body 61. Then hold the swing rod 84 and swing it back and forth to apply pressure. If there is a problem in the welding area, a gap will be generated at the welding position. Under the action of the spring, the second probe 88 will protrude into the gap, and at this time, the welding quality can be judged.
