Abstract
Description
Technical Field

[0002] Industrial grade magnesium oxide powder is a kind of high-purity magnesium oxide with the chemical formula of MgO. Electrical grade magnesium oxide powder is widely used in electric heating elements, cable insulation and electronic components due to its high purity, thermal conductivity and insulation. Magnesium oxide powder needs to be tested during the production process to ensure the quality of magnesium hydroxide powder and the consistency of product quality. When magnesium oxide powder is tested, due to the raw materials, process and other factors in the production process of electrical grade magnesium oxide powder, its quality may be somewhat uneven. Through a special sampling device, representative samples can be collected from products at different locations and batches, so as to better Accurately reflect the quality status of the entire batch of products. During the magnesium oxide powder sampling process, the user inserts the sampling tube into the magnesium oxide powder pile that needs to be sampled, and then samples and collects the magnesium oxide powder at the opening of the sampling tube. The magnesium oxide powder inside the sampling tube will enter the sampling bottle for collecting and storing the sampled magnesium oxide powder. Since the inner diameter space of the sampling tube remains unchanged, it is easy for the magnesium oxide powder to be squeezed and stuck in the sampling tube, resulting in poor fluidity of the magnesium oxide powder in the sampling tube, making it difficult for the magnesium oxide powder to quickly pass through the sampling tube into the sampling bottle, thereby increasing the time required for sampling the magnesium oxide powder.

Through the above technical solution: When in use; In the first step, when it is necessary to sample and test the magnesium oxide powder, the sampling tube 1 is inserted into the magnesium oxide powder pile to be sampled, and the magnesium oxide powder flows into the inside and deeper along the opening of the sampling tube 1. At this time, the servo motor 32 drives the cooperative column 33 to rotate inside the cooperative groove 31 and the movable sleeve 34, and the rotation of the cooperative column 33 drives the push block 35 to rotate at the same time, and the push block 35 rotates to form a conflict between its top and the inside of the contact groove 36 and push the contact groove 36, so that the movable sleeve 34 moves to the left along the inside of the cooperative groove 31, and the movable sleeve 34 moves to push the connecting seat 37 and the guide rod 24 to move at the same time. The guide rod 24 moves so that the portion of the guide rod 24 located inside the cooperative groove 31 moves toward the interior of the sampling tube 1, and the first spring 38 is squeezed between the connecting seat 37 and the cooperative groove 31, so that the guide rod 24 moves to push the circulation guide rod 21 and the global swivel 22 to move along the interior of the sampling tube 1. As the circulation guide rod 21 moves, it is used to push the magnesium oxide powder inside the sampling tube 1, and a distance is formed between the circulation guide rod 21 and the sampling tube 1 for part of the magnesium oxide powder to pass through, so that part of the magnesium oxide powder is temporarily separated inside the sampling tube 1, so that the magnesium oxide powder moves deep into the sampling tube 1 and falls into the interior of the sampling bottle 11.
[0021] In the second step, when the flow guide rod 21 moves inside the sampling tube 1, the rotation of the cooperative column 33 drives the push block 35 to rotate along the inside of one of the contact grooves 36 and form a conflict with it, pushing the movable sleeve 34 and the cooperative ear groove 39 to move at the same time, and then the push block 35 moves along the inside of one of the contact grooves 36 to the inside of the cooperative ear groove 39, and one end of the push block 35 forms a conflict with the inside of the cooperative ear groove 39. At this time, the push block 35 moves along the inside of the cooperative ear groove 39 and moves to the other contact groove 36 under continuous rotation. , and then the first spring 38 itself elastically gives a thrust to one side of the connecting seat 37 and the movable sleeve 34, so that the movable sleeve 34 moves and resets along the outside of the cooperative column 33, and the pushing block 35 keeps overlapping with another contact groove 36, and the movement of the movable sleeve 34 drives the flow guide rod 21 to move rightward along the sampling tube 1, so that the cooperative column 33 continuously rotates, driving the flow guide rod 21 and the guide rod 24 to move back and forth left and right inside the sampling tube 1, thereby accelerating the magnesium oxide powder inside the sampling tube 1 into the interior of the sampling bottle 11.
[0022] In the third step, when the circulation guide rod 21 moves inside the sampling tube 1 and the global swivel 22 rotates at one end of the circulation guide rod 21, the movement of the circulation guide rod 21 drives the fixed frame 44 installed inside it to move at the same time, and then the fixed frame 44 moves to drive the roller 52 to move along the displacement plate 56, and the displacement plate 56 and the roller 52 form a conflict and guide it. At this time, the roller 52 moves upward on the displacement plate 56, and the upward movement of the roller 52 pushes the base 51 to move upward at the same time, and the worm 43 moves upward along the fixed frame 44 under the push of the base 51, and the inside of the worm 43 moves upward along the outside of the rotating rod 45, and squeezes the third spring 55 between the top plate 54 and the worm 43, and the third spring 55 gives the top of the worm 43 a downward thrust through the elastic force of the third spring 55 itself, so that the third spring 55 can give the worm 43 The reaction force at one end ensures that the roller 52 installed at the bottom of the worm 43 is in stable contact with the displacement plate 56, so that the worm 43 moves upward and engages with the worm wheel 46 to drive the rotating rod 45 to rotate in the circulation guide rod 21, and the rotation of the rotating rod 45 drives the global swivel 22 to rotate along one end of the circulation guide rod 21. After the circulation guide rod 21 continues to move, the roller 52 moves to the middle position of the displacement plate 56, and then the roller 52 moves on the displacement plate 56 to another inclined position of the displacement plate 56. At this time, the roller 52 drives the worm 43 to move downward, and drives the rotating rod 45 to rotate forward and backward in the circulation guide rod 21, so that the global swivel 22 can be rotated along one end of the circulation guide rod 21 when the circulation guide rod 21 moves, so that the horizontally moving circulation guide rod 21 and the rotating global swivel 22 cooperate with each other.
[0023] In the fourth step, as the worm 43 and the roller 52 move downward along the displacement plate 56, the connecting seat 37 moves along the inside of the cooperative groove 31 and contacts with the positioning rod 41, pushing the positioning rod 41 to move along the inside of the cooperative groove 31 toward the inside of the circulation guide rod 21. Then the positioning rod 41 moves to push the displacement plate 56 and the circulation guide rod 21 to move simultaneously. During this process, the displacement plate 56 and the roller 52 move synchronously to provide short-term support for the roller 52 on the displacement plate 56, so that the global swivel 22 rotates intermittently on the circulation guide rod 21.
[0024] The above only describes certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, a person skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
