[0002] The halogen moisture meter is a rapid moisture detection instrument, mainly composed of an operating host, a tray, a sample tray, a heating detector and a ring-shaped halogen lamp. Its ring-shaped halogen heating ensures that the moisture in the sample can be quickly discharged and the sample can be dried evenly. After the drying process is completed, the final measured moisture content value is intuitively displayed on the display screen on the operating host. It is widely used in food, chemical, pharmaceutical and other fields.

[0003] The existing halogen moisture analyzers still have the following problems during use: 1. Due to the limitation of testing stations, the testing efficiency is low when testing multiple groups of samples, and the comparison of test results of samples in the same group is slow; 2.

The use of a sample tray with a handle still poses a risk of scalding, and the handle-type sample tray is prone to cause the center of gravity of the sample tray to deviate, and the sealing state of the heating chamber to leak; 3. When using a fully automated loading and unloading tray, how to solve the problem of uniform material addition and how to implement thorough material discharge during unloading to prevent residual material from affecting the measurement results of the next sample are issues that need to be urgently addressed.

[0028] In order to solve the problem of automatic material retrieval, the self-discharging material tray assembly 3 in the present invention includes a material guide tray 302 placed on the top of the bracket 1303, and a sample tray 301 is fixed to the top of the material guide tray 302 by bolts, and a plurality of material discharge slots 312 for discharging samples are provided at the bottom of the sample tray 301, and the plurality of material discharge slots 312 are distributed in a circular array around the center line of the sample tray 301, and a rotating material blocking frame 307 for simultaneously blocking the plurality of material discharge slots 312 is rotatably connected to the bottom of the sample tray 301, and a magnetic attraction mechanism for fixing the position of the rotating material blocking frame 307 is provided between the rotating material blocking frame 307 and the sample tray 301, and a material discharge port 306 is rotatably connected in the material discharge port 306. The discharge pipe 303 and the guide plate 302 are provided with a converging slope 305 for guiding the sample material and converging it to the discharge port 306. The bottom of the guide plate 302 is provided with a positioning ring groove 304 that matches the bracket 1303. The bottom plate 703 is provided with a transmission component 14 for driving the storage type discharge pipe 303 and the rotating type material blocking frame 307 to perform a rotational action. The transmission component 14 includes a positioning cylinder 1401 fixed in the bottom plate 703 through a side mounting frame 1402. Both sides of the positioning cylinder 1401 are provided with a lower vertical groove 1407, a driving spiral groove 1408 and an upper vertical groove 1409 that are connected to each other. The bottom of the storage type discharge pipe 303 is fixed with a lower mounting frame 1410 by bolts. The lower mounting frame 1410 is fixed with a mounting block 140 The driving rod 1403 matched with the positioning cylinder 1401 is clamped, and the bottom end of the driving rod 1403 is fixed with two guide rods 1406 that can move along the lower vertical groove 1407, the driving spiral groove 1408 and the upper vertical groove 1409 by bolts. The top end of the driving rod 1403 passes through the storage type discharge pipe 303 and is keyed to the semi-toothed disc 1404. The bottom of the rotary material blocking frame 307 is fixed with a rack 308 matched with the semi-toothed disc 1404 by bolts. The magnetic attraction mechanism includes a plurality of positioning magnetic plates 309 fixed to the bottom of the sample plate 301 by bolts. The bottom of the rotary material blocking frame 307 is provided with a plurality of mounting grooves 310 corresponding to the positioning magnetic plates 309, and a magnetic block 308 is fixed in the mounting groove 310 by bolts. 11. When the sample material is taken out quickly, the lifting assembly 6 first lifts the guide plate 302 to separate the guide plate 302 from the weighing assembly 13. At this time, the guide plate 302 drives the storage type discharge tube 303 and the driving rod 1403 to move upward. The driving rod 1403 moves upward to drive the two guide rods 1406 to move upward along the lower vertical groove 1407 until the guide rod 1406 moves to the driving spiral groove 1408, so that the guide rod 1406 moves along the driving spiral groove 1408 and drives the driving rod 1403 to rotate, until the guide rod 1406 moves from the driving spiral groove 1408 to the upper vertical groove 1409, and the guide rod 1406 drives the driving rod 1403 to complete a 180° rotation operation.At this time, the driving rod 1403 rotates through the mounting block 1405 to drive the lower mounting frame 1410 and the retractable discharge pipe 303 to flip outward until the retractable discharge pipe 303 flips 180° and the end of the retractable discharge pipe 303 flips to above the collection box 5. At the same time, the driving rod 1403 rotates to drive the semi-toothed disc 1404 to rotate. Since the semi-toothed disc 1404 has only partial teeth, the semi-toothed disc 1404 does not contact the rack 308 during the initial rotation. When the driving rod 1403 rotates to drive the semi-toothed disc 1404 to rotate to 120°, the teeth of the semi-toothed disc 1404 and the rack 308 are in contact. 8 is meshed, at this time, the rack 308 is driven by the force to drive the rotary material stopper 307 to rotate around the sample plate 301, until the half toothed plate 1404 rotates to 180 degrees, the rotary material stopper 307 stops rotating, at this time the rotary material stopper 307 is hidden at the bottom of the sample plate 301, and the material discharge slot 312 opened in the sample plate 301 is completely exposed, and during the opening of the material discharge slot 312, the sample materials fall into the guide plate 302 under the action of their own gravity, and pass through the confluence slope 305 to make the sample materials gather at the discharge port 306, and are discharged into the collection box 5 through the storage type discharge pipe 303. During the initial discharge of materials until the materials are completely discharged, the end of the storage type discharge pipe 303 is still located above the collection box 5. When the sample material is added, the guide plate 302 is lowered by the lifting assembly 6, so that the guide rod 1406 moves along the upper vertical groove 1409, the driving spiral groove 1408 and the lower vertical groove 1407, so that the driving rod 1403 rotates in the opposite direction. At this time, the driving rod 1403 rotates in the opposite direction to drive the semi-toothed plate 1404 to rotate in the opposite direction and reset, and the rack 308 is forced to drive the rotating material stopper 307 to rotate in the opposite direction around the sample plate 301 and reset. At this time, the positioning magnetic plate 30 9 generates magnetic attraction with the magnetic block 311, so that the rotation position of the rotating material stopper 307 is magnetically fixed, and the driving rod 1403 rotates in the opposite direction and drives the storage type discharge tube 303 to flip inward and reset, and the storage type discharge tube 303 is stored, and then the sample material is added to the sample tray 301. At this time, the vibration component 9 operates and makes the sample material in the sample tray 301 vibrate and shake itself evenly, and then the lifting component 6 drives the guide tray 302 and the sample tray 301 to descend until the sample tray 301 completely falls into the detection mold core 7 and contacts and is supported by the weighing component 13.

[0029] The lifting assembly 6 in the present invention includes a lifting frame 602 inserted into the bottom plate 703, and a lifting electric push rod 601 is provided at the bottom of the bottom plate 703 to drive the lifting frame 602 to move in the vertical direction. A plurality of positioning sleeves 603 cooperating with the lifting frame 602 are fixed by bolts at the bottom of the guide plate 302. By starting the lifting electric push rod 601, the lifting electric push rod 601 shortens and drives the lifting frame 602 to move upward, and the lifting frame 602 is inserted into the positioning sleeve 603, and then the lifting operation of the guide plate 302 and the sample plate 301 is performed. The vibration assembly 9 includes an upper limit ring 901 and a lower limit ring 904 fixed to the bottom of the lifting frame 602 by bolts, and a middle slide plate 903 in contact with the lifting frame 602 is provided between the upper limit ring 901 and the lower limit ring 904. 03 is fixed to the lifting electric push rod 601, the top and bottom of the middle slide plate 903 are respectively fixed to the upper limit ring 901 and the lower limit ring 904 by multiple springs 902, and the bottom of the lifting frame 602 is fixed with a vibration motor 905 by bolts. By starting the vibration motor 905, the vibration motor 905 rotates to generate vibration, and because the lifting electric push rod 601 is fixed to the middle slide plate 903, and the middle slide plate 903 is fixed to the upper limit ring 901 and the lower limit ring 904 by multiple groups of springs 902, the middle slide plate 903 is softly connected with the upper limit ring 901 and the lower limit ring 904. Therefore, when the vibration motor 905 vibrates, it can drive the lifting frame 602 to vibrate, and the lifting frame 602 vibrates, which drives the vibration operation of the guide plate 302 and the sample plate 301 through the positioning sleeve 603.

[0030] The positioning assembly 8 in the present invention includes a slot-type photoelectric switch 804 fixed to the bottom of the base plate 703 by bolts, and a sensing frame 1 801, a sensing frame 2 802 and a sensing frame 3 803 are fixed to one side of the lifting frame 602 by bolts. The sensing frame 1 801, the sensing frame 2 802 and the sensing frame 3 803 correspond to the measuring position, the discharging position and the feeding position of the lifting frame 602 respectively, so that the lifting frame 602 drives the sensing frame 1 801, the sensing frame 2 802 and the sensing frame 3 803 to sense the slot-type photoelectric switch 804 while lifting and lowering, thereby realizing the elongation and shortening size of the lifting electric push rod 601 and the vibration time of the vibration motor 905, with a high degree of automation and more accurate automatic discharging.

[0031] The display, temperature sensor, halogen heating tube 12, lifting electric push rod 601, slot type photoelectric switch 804, vibration motor 905, flip cover electric push rod 10 and weighing sensor 1302 are electrically connected, so as to realize full automatic control by means of the set program.

[0032] The present invention is divided into the following steps when used: S1: First, the lifting electric push rod 601 is extended to drive the lifting frame 602 to move downward and lower the guide plate 302, so that the guide rod 1406 moves along the upper vertical groove 1409, the driving spiral groove 1408 and the lower vertical groove 1407, so that the driving rod 1403 rotates in the opposite direction. At this time, the driving rod 1403 rotates in the opposite direction to drive the semi-toothed plate 1404 to rotate in the opposite direction and reset, and the rack 308 is forced to drive the rotary material stopper 307 to rotate in the opposite direction around the sample plate 301 and reset. At this time, the positioning magnetic plate 309 and the magnetic block 311 generate magnetic attraction, so that the rotation position of the rotary material stopper 307 is magnetically fixed, and the driving rod 1403 rotates in the opposite direction and drives the storage type discharge pipe 303 to flip inward and reset, and the storage type discharge pipe 303 is stored. S2: Then add the sample material into the sample tray 301, and start the vibration motor 905 at this time. The vibration motor 905 rotates to generate vibration, and because the lifting electric push rod 601 is fixed to the middle slide plate 903, and the middle slide plate 903 is fixed to the upper limit ring 901 and the lower limit ring 904 through multiple sets of springs 902, so that the middle slide plate 903 is softly connected with the upper limit ring 901 and the lower limit ring 904. Therefore, when the vibration motor 905 vibrates, it can drive the lifting frame 602 to vibrate. When the lifting frame 602 vibrates, it drives the guide plate 302 and the sample plate 301 to vibrate through the positioning sleeve 603, and makes the sample material in the sample tray 301 vibrate and realize self-shaking. Then the lifting component 6 drives the guide plate 302 and the sample tray 301 to descend until the sample tray 301 completely falls into the detection core 7, and contacts and is supported by the weighing component 13. At this time, the lifting frame 602 is separated from the positioning sleeve 603; S3: Then, the flip cover electric push rod 10 is started to drive the upper cover 4 to flip downward, and the lampshade 11 and the detection mold core 7 are closed, and then the sample material in the sample tray 301 is heated by the halogen heating tube 12, and the moisture content of the sample material is determined by the cooperation of the temperature sensor, the weighing component 13 and the display; S4: After the moisture content of the sample material is determined, when the sample material needs to be taken out, the lifting assembly 6 lifts the guide plate 302 to separate the guide plate 302 from the weighing assembly 13. At this time, the guide plate 302 drives the storage type discharge tube 303 and the driving rod 1403 to move upward. The driving rod 1403 moves upward to drive the two guide rods 1406 to move upward along the lower vertical groove 1407 until the guide rod 1406 moves to the driving spiral groove 1408, so that the guide rod 1406 moves along the driving spiral groove 1408. The groove 1408 moves and drives the driving rod 1403 to rotate until the guide rod 1406 moves from the driving spiral groove 1408 to the upper vertical groove 1409, and the guide rod 1406 drives the driving rod 1403 to complete a 180° rotation operation. At this time, the driving rod 1403 rotates through the mounting block 1405 to drive the lower mounting frame 1410 and the retractable discharge pipe 303 to flip outward, until the retractable discharge pipe 303 flips 180° and the end of the retractable discharge pipe 303 flips to the top of the collection box 5; S5: At the same time, the driving rod 1403 rotates to drive the semi-toothed disc 1404 to rotate. Since the semi-toothed disc 1404 has only partial teeth, the semi-toothed disc 1404 does not contact the rack 308 during the initial rotation. When the driving rod 1403 rotates to drive the semi-toothed disc 1404 to rotate to 120°, the teeth of the semi-toothed disc 1404 mesh with the rack 308. At this time, the rack 308 is forced to drive the rotating material stopper 307 to rotate around the sample disc 301 until the semi-toothed disc 1404 When rotating to 180°, the rotating material stopper 307 stops rotating. At this time, the rotating material stopper 307 is hidden at the bottom of the sample tray 301, and the material discharge slot 312 opened in the sample tray 301 is completely exposed. During the process of opening the material discharge slot 312, the sample materials gradually fall into the guide tray 302 under the action of their own gravity, and are gathered at the discharge port 306 through the converging slope 305, and are discharged into the collection box 5 through the storage type discharge pipe 303. S6: At this time, the vibration component 9 operates and causes the sample plate 301, the material guide plate 302 and the storage type discharge pipe 303 to resonate, so that the sample material is completely discharged.
