Description

Technical Field

[0001] The utility model relates to the technical field of polyamide production detection, in particular to a PA66 moisture measuring device. Background Art

[0002] PA66, also known as polyamide 66 or nylon 66, is made by the condensation of adipic acid and hexamethylenediamine. It is widely used in the automotive industry, instrument housings, and other products that require impact resistance and high strength. Since PA66 cannot evaporate and dry its internal moisture during production, it contains a certain amount of moisture. However, as long as the moisture does not exceed the specified range, it will not affect its use. Therefore, after processing PA66, the PA66 particles need to be tested for moisture, generally using a moisture meter for testing.

[0003] The "Polyamide Moisture Measuring Device" with authorization announcement number "CN218331080U" includes a moisture meter base, the top of which is hingedly connected to a flip cover, a motor fixed to the top of the inner cavity of the equipment box, the output shaft of which is fixed to a cylindrical box, the surface of which rotates on the bottom of the equipment box via a bearing, the bottom of the cylindrical box extending through the inner cavity of the groove, a fixed plate fixed to the surface of the cylindrical box, the bottom of which is provided with two rows of long rods, the bottoms of which extend downward to the inner cavity of the storage tray, and an adjustment assembly provided in the inner cavity of the cylindrical box, which drives the long rods to rotate through the fixed plate to push the accumulated polyamide particles;

[0004] In the above-mentioned prior art, when the long rod rotates to push the accumulated polyamide particles, since the top of the storage tray is in an exposed state, the accumulated polyamide particles are easily caused to slide out when the long rod is rotated. At the same time, the movable frame is driven downward by the piston rod of the micro-electric push rod, and the side wall of the movable frame is driven to flatten the uneven polyamide particles. However, the position of the movable frame is fixed at this time. When the accumulated polyamide particles are flattened, the polyamide particles are easily over-extruded, causing the polyamide particles to fly, thereby affecting the detection accuracy.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a PA66 moisture measuring device includes a moisture meter 1, a carrying dish 2 for carrying PA66 particles is installed in the middle of the moisture meter 1, a top cover 3 is rotatably installed on the top of the moisture meter 1, a heating component 4 for heating the PA66 particles is fixedly installed in the middle of the top cover 3, a cover ring 5 for sealing the carrying dish 2 is installed in the middle of the inner wall of the top cover 3 corresponding to the position of the carrying dish 2, a mounting rod 6 is installed below the cover ring 5, a pusher column 7 for pushing the PA66 particles is fixedly installed at an equidistant bottom of one end of the mounting rod 6, and a pusher block 8 for smoothing the PA66 particles is installed at the bottom of the other end of the mounting rod 6.

[0023] like Figures 1 to 4 As shown, several of the pushing columns 7 are arranged in a staggered manner.

[0024] Improve the effect of the push column 7 on pushing PA66 particles.

[0025] like Figures 1 to 4 As shown, a fixing frame 9 is fixedly installed in the middle of the inner wall of the top cover 3, a motor 10 is fixedly installed in the middle of the fixing frame 9, the output end of the motor 10 is rotatably installed with a mounting ring 11 through a bearing, the cover ring 5 is movably installed below the mounting ring 11, the output end of the motor 10 is set through the middle of the cover ring 5, and the output end of the motor 10 is fixedly connected to the mounting rod 6.

[0026] The motor 10 drives the mounting rod 6 to rotate, and the pushing column 7 pushes the PA66 particles to break up the accumulated PA66 particles. At the same time, the pushing block 8 rotates to smooth the PA66 particles to prevent the PA66 particles from accumulating.

[0027] like Figures 1 to 4 As shown, the periphery of the mounting ring 11 is provided with limiting holes 12 in a ring array with the central axis of the mounting ring 11 as the axis, and a limiting rod 13 is fixedly installed at the position of the limiting hole 12 on the top of the cover ring 5. The limiting rod 13 is slidably connected to the limiting hole 12, and a protective spring 14 is sleeved on the outer side of one end of the limiting rod 13 close to the cover ring 5. One end of the protective spring 14 is fixedly connected to the end of the cover ring 5 close to the limiting rod 13, and the other end of the protective spring 14 is fixedly connected to the bottom end of the mounting ring 11.

[0028] When the cover ring 5 is covering the carrier dish 2, the cover ring 5 will first be squeezed by the carrier dish 2, driving the limiting rod 13 on the top of the cover ring 5 to slide inside the limiting hole 12. At this time, the protective spring 14 is in a compressed state. When the cover ring 5 moves to a horizontal state, the cover ring 5 will fit the top of the carrier dish 2 under the pressure of the protective spring 14, which is used to seal the top of the carrier dish 2 and prevent the PA66 particles from being pushed out of the carrier dish 2.

[0029] like Figures 1 to 4 As shown, a slide rod 15 is symmetrically fixedly installed on the top of the pusher block 8, and a slide hole 16 is opened at the position of the installation rod 6 corresponding to the slide rod 15, and the slide hole 16 is slidably connected to the slide rod 15.

[0035] The utility model provides a PA66 moisture measurement device, the specific working principle is as follows:

[0036] When the device is in use, PA66 particles are placed inside the carrier dish 2 and the top cover 3 is covered. At this time, the cover ring 5 will cover the top of the carrier dish 2. When the cover ring 5 covers the top of the carrier dish 2, the cover ring 5 will first be squeezed by the carrier dish 2 and drive the limit rod 13 on the top of the cover ring 5 to slide inside the limit hole 12. At this time, the protective spring 14 is in a compressed state. When the cover ring 5 moves to a horizontal state, the cover ring 5 will fit the top of the carrier dish 2 under the pressure of the protective spring 14 to seal the top of the carrier dish 2. At this time, the cover ring 5 will be fixed by friction. On the carrier dish 2, the moisture meter 1 is operated. The motor 10 drives the mounting rod 6 to rotate, and the pusher column 7 pushes the PA66 particles to break up the accumulated PA66 particles. At the same time, the pusher block 8 rotates to smooth the PA66 particles and prevent them from accumulating. During the testing process, the pusher column 7 can be controlled to push the PA66 particles, and the pusher block 8 can be rotated to lift the PA66 particles, thereby changing the position of the PA66 particles inside the carrier dish 2 and improving the heating effect of the PA66 particles.
