Description

Technical Field

[0001] This utility model relates to the field of chemical fiber filament testing technology, specifically to a water bath sample placement device for filament boiling water shrinkage testing. Background Technology

[0002] The standard GB / T 6505-2017 "Test Method for Heat Shrinkage Rate of Chemical Fiber Filaments" specifies an instrumental measurement method for drawn filaments. During the boiling treatment stage, the filament rack holding the sample is vertically immersed in boiling water for a total boiling time of (30±5) min, ensuring the water remains boiling throughout the test. After boiling, the filament rack is carefully removed, allowed to drip water for 10 minutes, and then placed in an oven. Currently, the laboratory uses manual methods for placing and removing the wire strand frame. The entire placement and retrieval process requires the operator to stand beside the constant temperature water bath and carefully and slowly place the wire strand frame hanging from the pendant. The constant temperature water bath is 95cm high, and the wire strand frame and pendant together are about 80cm high. For inspectors who are not tall enough, they need to stand on tiptoe to ensure that the wire strand frame is placed vertically into the constant temperature water bath. During the slow placement and retrieval of the wire strand frame, it is necessary to prevent steam burns and ensure that the wire is vertically downward to prevent it from being blown up by the boiling water, which could cause the wire to detach from the weight and become entangled, resulting in inconvenience and safety hazards.

The lifting platform 2 is disposed inside the water bath body 1. The lifting screw motor 3 is fixed to the water bath body 1 by a support 7. The screw 3.1 of the lifting screw motor 3 extends into the water bath body 1 and connects to the lifting platform 2. The bottom of the screw 3.1 is supported and fixed to the bottom of the water bath body 1. The lifting cylinder 5 is fixedly disposed on one side of the water bath body 1. The top of the movable rod 5.1 of the lifting cylinder 5 is provided with a rotating arm 6. The cylinder body of the lifting cylinder 3 is provided with a fixing plate 8. The fixing plate 8 is provided with a positioning boss 9. The stranding frame 4, on which the long filaments are installed, is placed on the fixing plate 8. The center hole of the bottom plate of the stranding frame 4 is inserted into the positioning boss 9 to achieve the initial positioning of the stranding frame 4.

[0020] The lifting platform 2 is provided with a positioning rod 10 at its center. The positioning rod 10 is used to fix the position of the wire winding frame 4. The front and rear sides of the screw 3.1 are provided with guide rods 11 in parallel. The guide rods 11 pass through the lifting platform 2. The two ends of the guide rods 11 are fixed to the support 7 and the bottom of the water bath body 1, respectively. The lifting screw motor 3 rotates to drive the lifting platform 2 to rise and fall. The guide rods 11 ensure that the lifting platform rises and falls smoothly.

[0021] The rotating boom 6 includes a rotating platform 6.1, a crossbar 6.2, a gripper cylinder 6.3, and a rotary drive motor 6.4. The top of the movable rod 5.1 of the lifting cylinder 5 is rotatably connected to the rotating platform 6.1 via a bearing. The rotating platform 6.1 is connected to the crossbar 6.2, and the gripper cylinder 6.3 is fixedly mounted on the crossbar 6.2. The gripper cylinder 6.3 is used to grip the wire strand frame 4. The rotary drive motor 6.4 is fixed on the rotating platform 6.1, and the output end of the rotary drive motor 6.4 is connected to a drive gear 6.5.

[0022] Operating instructions:

[0023] The wire stranding frame 4 with the long wire installed is placed on the fixed plate 8. The gripper cylinder 6.3 on the rotating boom 6 clamps the wire stranding frame 4. The lifting cylinder 5 drives the wire stranding frame 4 to rise. The rotating drive motor 6.4 drives the rotating boom and the wire stranding frame 4 on it to rotate to the top of the water bath body 1.

[0024] The lifting screw motor 3 drives the lifting platform 2 to rise. During the rising process, the positioning rod 10 is inserted into the center hole of the wire twisting frame 4 to achieve vertical limit of the wire twisting frame 4 and prevent the wire twisting frame 4 from tilting during the lifting process. When the bottom of the wire twisting frame 4 is in contact with the lifting platform 2, the lifting screw motor 3 rotates in the opposite direction, and the lifting platform 2 drives the wire twisting frame 4 on it to descend synchronously, so that the wire twisting frame 4 enters the water bath body 1 in a vertical state.

[0025] After the water bath is heated, the lifting screw motor 3 drives the lifting platform 2 and the wire stranding frame 4 on it to rise until they reach the designated position. The rotating arm 6 clamps the wire stranding frame 4, and the lifting screw motor 3 drives the lifting platform 2 to descend. The wire stranding frame 4 is released from its vertical limit. The rotating drive motor 6.4 drives the rotating arm to rotate above the fixed plate 8 outside the water bath. The lifting cylinder 5 drives the rotating arm 6 and the wire stranding frame 4 on it to descend onto the fixed plate 8. This completes the placement and sampling process of the wire stranding frame 4.
