Description

Technical Field

[0001] The utility model relates to the technical field of migration amount and non-volatile matter determination, and particularly relates to a device for determining migration amount and non-volatile matter. Background Technique

[0002] The statements in this part only provide the background technique related to the utility model and do not necessarily constitute the prior art.

[0003] When measuring the migration amount and non-volatile matter of food packaging materials, drug packaging materials, etc., the test dish containing the sample solution needs to be first evaporated to dryness, then dried, and finally weighed to obtain the residue mass; in order to obtain a high-precision residue mass, a high-precision electronic balance is required for weighing. When the existing migration amount and non-volatile matter detector uses an electronic balance, most of them place the electronic balance below or closely arranged under the test chamber, and the weighing of the test dish by the balance is carried out in the test chamber.

[0004] The inventor found that the existing migration amount and non-volatile matter detector has the following problems:

[0005] (1) Since the high-precision electronic balance is placed below or closely arranged under the test chamber, the test chamber with repeated heating and cooling makes the balance in a complex and changeable temperature, humidity and electromagnetic environment, affecting the accuracy of weighing data;

[0006] (2) The weighing of the test dish by the balance is carried out in the test chamber. The test chamber is mostly a water bath or an oven. When the test chamber works as a water bath or an oven, although heat insulation, moisture insulation and other measures are taken above the balance communicated with the test chamber, it is very difficult to completely prevent the entry of high-temperature and high-humidity gases, which will cause damage to the balance and affect the weighing accuracy;

[0007] (3) Before weighing the test dish, the evaporation chamber needs to be cooled. Only local cooling is adopted, and the cooling time is long, affecting the test efficiency. Content of the Utility Model

The weighing mechanism is not affected by the high temperature and high humidity during evaporation, which can effectively ensure the service life and weighing accuracy of the weighing mechanism. At the same time, the weighing pan of the weighing mechanism is located outside the test chamber, avoiding contamination of the weighing pan by evaporation or baking in the test chamber, and the weighing data is more accurate.

The sealed test chamber can be opened by the chamber door or the upper chamber assembly, and then the test dish can be moved to the weighing mechanism by the cup moving mechanism, or the test dish can be moved back to the test chamber. The whole process is automated, improving the test efficiency on the premise of ensuring weighing accuracy.

[0059] 3. The present utility model innovatively proposes a device for measuring migration amount and non-volatile matter. The weighing mechanism and the test chamber are both arranged inside the housing, and an exhaust fan is provided on the housing, which can ensure the stability of the internal environment of the housing, effectively separate the weighing environment from the variable environment of the test chamber, make the weighing environment inside the housing more stable, the weighing speed faster, and the weighing data more accurate.

[0104] In this implementation, the cup moving mechanism 1700 and the weighing mechanism 1800 are arranged on the same side of the test chamber 1300 (the relative positions of the two can be arranged arbitrarily, as Figure 25 、 Figure 27 、 Figure 28 and Figure 29 shown). When the chamber door assembly 1400 opens the test chamber 1300, the cup moving mechanism 1700 can enter the test chamber 1300, cooperate with the rotary lifting mechanism 1006 to take out the test dish 1004, and place it on the weighing mechanism 1800 for weighing. It can also be operated in reverse to put the test dish 1004 back into the test chamber 1300 from the weighing mechanism 1800. The exhaust fan 1009 is fixed on the outer cover 1002 and is used to exhaust the preheating of the equipment inside the outer cover to keep the temperature inside the equipment consistent with the ambient temperature.

[0105] In this implementation, as Figure 2As shown in the figure, the test chamber 1300 includes a heating plate 1301, a test chamber body 1310, a circumferential thermal insulation layer 1312, and a test chamber outer shell 1313. The heating plate 1301 is fixed to the bottom of the test chamber body 1310. The circumferential thermal insulation layer 1312 wraps the heating plate 1301 and the test chamber body 1310 for heat insulation. The outer layer of the circumferential thermal insulation layer 1312 is fixed to the test chamber outer shell 1313. The heating plate 1301 can heat the test chamber body 1310 to reach the temperature required for the test, for the evaporation of the sample liquid or the baking of the test dish 1004. The heating plate 1301 is provided with at least one heating pipe and a cooling pipeline. When the heating plate 1301 needs to generate heat, power is applied between the terminal a 1303 and the terminal b 1304. When the heating plate 1301 needs to be quickly cooled, the power supply of the heating pipe is disconnected, and cooling water or cooling gas is introduced into the cooling pipeline of the heating plate 1301 through the cooling pipe inlet 1302 and the heating plate cooling pipe outlet 1305.

[0106] More specifically, a water inlet and outlet 1314 is provided at the bottom of the test chamber body 1310, through which water can be injected into or discharged from the chamber for water bath evaporation. A circumferential cavity 1309, a circumferential inlet 1306, and a circumferential outlet 1307 are provided around the test chamber body 1310. When the test chamber 1300 needs to be cooled, cooling water or cooling gas is introduced into the circumferential cavity 1309 of the test chamber through the circumferential inlet 1306 and the circumferential outlet 1307 to quickly cool the test chamber body 1310. The test chamber body 1310 is also provided with at least one lower exhaust port 1308 and one upper exhaust port 1311 of the test chamber. When the sample liquid evaporates in the chamber, the steam generated by the evaporation is discharged.

[0107] In this implementation, as Figure 12 、 Figure 13 、 Figure 19 、 Figure 20 and Figure 21 shown, the chamber door assembly 1400 includes a sealing strip 1401, a chamber door positioning block 1402, a chamber door 1403, and an opening cylinder 1404. The sealing strip 1401, the chamber door positioning block 1402, and the cylinder body of the opening cylinder 1404 (i.e., the chamber door driving mechanism) are directly fixed to the test chamber outer shell 1313. The chamber door 1403 is fixed to the cylinder rod of the opening cylinder 1404. Driven by the cylinder rod of the opening cylinder 1404, the chamber door 1403 retracts the cylinder rod to open the chamber door 1403, or extends the cylinder rod to close the chamber door 1403, and is limited by the chamber door positioning block 1402 to compress the sealing strip 1401 to seal the test chamber body 1310.

[0108] The cup moving mechanism 1700 in this implementation, as Figure 3As shown in the figure, it includes a rotary lifting mechanism 1701 (i.e., the second rotary lifting mechanism), a connecting shaft 1702, a rotary fixing plate 1703, a slider 1704, a connecting block 1705, a sliding plate 1706, a slide rail 1707 and a sliding cylinder 1708 (i.e., the first linear driving mechanism). The connecting shaft 1702 is rigidly connected to the rotary lifting mechanism 1701, the rotary fixing plate 1703 is rigidly connected to the connecting shaft 1702, the cylinder bodies of the slide rail 1707 and the sliding cylinder 1708 are rigidly connected to the rotary fixing plate 1703, the slider 1704 and the connecting block 1705 are rigidly connected to the sliding plate 1706, the sliding plate 1706 is slidably connected to the slide rail 1707 through the slider, and the sliding plate 1706 is fixedly connected to the piston rod of the sliding cylinder 1708 through the connecting block 1705. In this way, the sliding cylinder 1708 can drive the sliding plate 1706 to slide, the rotary lifting mechanism 1701 can drive the sliding plate 1706 to rotate and move up and down. A bayonet is provided on the sliding plate 1706, which can be inserted under the rim of the test dish 1004 to position and lift the test dish 1004, and the cup moving mechanism 1700 realizes the transfer action of the test dish 1004.

[0109] In this implementation manner, the weighing mechanism 1800 includes an electronic balance 1801 and a weighing pan 1802. The weighing pan 1802 is fixed on the weighing column of the electronic balance 1801. When weighing, the test dish 1004 is placed on the weighing pan 1802, and the electronic balance 1801 weighs the test dish 1004.

[0110] The working process of the above-mentioned migration amount and non-volatile matter measuring device specifically includes:

[0111] (1) Empty cup test: Place the washed test dish 1004 into the positioning hole of the cup tray 1005. The chamber door assembly 1400 closes the test chamber 1300. The heating plate 1301 heats and controls the temperature inside the test chamber body 1310 to bake the test dish 1004. After reaching the baking time, turn off the heating plate 1301. Pass cooling water into the cooling pipelines of the peripheral cavity 1309 of the test chamber and the heating plate 1301 to quickly cool the test chamber body 1310 to room temperature, thereby quickly cooling the test dish 1004. Then, the chamber door assembly 1400 opens the test chamber 1300. The rotary lifting mechanism 1006 drives the cup tray 1005 to lift the test dish 1004. The cup moving mechanism 1700 rises and rotates the sliding plate 1706 to align it with the chamber door of the test chamber 1300. The sliding plate 1706 extends to below the rim of the test dish 1004. The rotary lifting mechanism 1006 drives the cup tray 1005 to lower, and the test dish 1004 falls onto the sliding plate 1706. The sliding plate 1706 retracts, rotates, and descends to drive the test dish 1004 to fall onto the weighing pan 1802 to weigh the test dish 1004 and obtain the cup mass. Operate in reverse, then place the test dish 1004 back, and the rotary lifting mechanism 1006 moves to the next test dish 1004 to complete the weighing of all test dishes in sequence. After completing the weighing of all test dishes, the chamber door assembly 1400 closes the test chamber 1300, and repeat the previous baking and cooling of the test chamber body 1310 and the weighing of the test dish until the mass of the test dish is constant, denoted as the empty cup mass M1.

[0112] (2) Specimen cup test: Add the sample solution into the already weighed test dish 1004. The cavity door assembly 1400 closes the test cavity 1300. Add pure water or distilled water into the test cavity 1310 through the water inlet and outlet 1314. The heating plate 1301 heats up, and the sample solution in the test dish 1004 is evaporated through a water bath. After the sample solution evaporation is completed, drain the water in the test cavity 1310 through the water inlet and outlet 1314. The heating plate 1301 continues to heat and control the temperature in the test cavity 1310 to bake the test dish 1004. After reaching the baking time, turn off the heating plate 1301, and introduce cooling water into the cooling pipelines of the peripheral cavity 1309 of the test cavity and the heating plate 1301 to quickly cool the test cavity 1310 to room temperature, and then quickly cool the test dish 1004. Then, the cavity door assembly 1400 opens the test cavity 1300. The rotary lifting mechanism 1006 drives the cup tray 1005 to lift the test dish 1004. The cup moving mechanism 1700 rises, and rotates the sliding plate 1706 to align with the cavity door of the test cavity 1300. The sliding plate 1706 extends below the rim of the test dish 1004. The rotary lifting mechanism 1006 drives the cup tray 1005 to lower, and the test dish 1004 falls onto the sliding plate 1706. The sliding plate 1706 retracts, rotates, and descends to drive the test dish 1004 to fall onto the weighing pan 1802 to weigh the test dish 1004 and obtain the cup mass. Operate in reverse, then put the test dish 1004 back, and the rotary lifting mechanism 1006 moves to the next test dish 1004 to complete the weighing of all test dishes in sequence; after completing the weighing of all test dishes, the cavity door assembly 1400 closes the test cavity 1300, repeat the baking and cooling of the test cavity 1310 and the weighing of the test dish before until the mass of the test dish is constant, denoted as the specimen cup mass M2. The difference between the specimen cup mass M2 and the empty cup mass M1 is denoted as the residue mass.

[0113] It can be understood that, as Figure 30 shown, the test dish can be directly clamped by the clamping jaw 4107 at the end of the sliding plate to replace the bayonet; as Figure 31 shown, the cup moving mechanism includes: a second rotary lifting mechanism 1701, a connecting shaft 1702, a rotary fixing plate 1703, a third linear driving mechanism 4108, and a sliding plate 4104. The connecting shaft 1702 is rigidly connected to the output shaft of the second rotary lifting mechanism 1701, and the rotary fixing plate 1703 is rigidly connected to the connecting shaft 1702;

[0114] The third linear driving mechanism 4108 is fixed on the rotary fixing plate 1703. The output end of the third linear driving mechanism 4108 is connected to the sliding plate 4104. The sliding plate 4104 is provided with a bayonet for inserting below the rim of the test dish; or, a clamping jaw 4107 for clamping the test dish is connected to the end of the sliding plate to replace the bayonet, as Figure 32 shown.

[0115] In another second implementation, the test chamber 1300 can also adopt an upper cover opening method, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 shown, the test chamber 1300 includes an upper cover assembly 2100, including an upper cover plate 2101, an upper cover insulation layer 2105, an upper cover outer shell 2106, a chamber sealing strip 2107, an upper cover connection block 2108, and an opening cylinder 2109 (i.e., an opening driving mechanism). The outer side of the upper cover plate 2101 is covered with the upper cover insulation layer 2105, the upper cover insulation layer 2105 is covered with the upper cover outer shell 2106, the upper cover connection block 2108 is fixed on the upper cover outer shell 2106, the cylinder body of the opening cylinder 2109 is fixed on the test chamber outer shell 1313 (or can be directly fixed on the bottom plate), the cylinder rod of the opening cylinder 2109 is fixedly connected with the upper cover connection block 2108, and the chamber sealing strip 2107 is fixed on the test chamber body 1310.

[0116] In the second implementation, the upper cover plate 2101 is a hollow structure, internally provided with an upper cover cooling cavity 2104, an upper cover cooling cavity inlet 2102, and an upper cover cooling cavity outlet 2103. Cooling water or cooling gas is introduced into the upper cover cooling cavity 2104 to controllably temperature or rapidly cool down the upper cover plate 2101, and cooperate to achieve rapid cooling of the test chamber body 1310; preferably, there are two opening cylinders 2109, which can drive the upper cover assembly 2100 to rise to open the test chamber body 1310 and descend to compress the chamber sealing strip 2107 to seal the test chamber body 1310.

[0117] In another third implementation, such as Figure 8 , Figure 9 , Figure 11 , Figure 12 and Figure 13As shown in the figure, the cup moving mechanism 1700 can also be a cup grasping mechanism 3100. The cup grasping mechanism 3100 includes a rotary lifting mechanism 3101 (i.e., the second rotary lifting mechanism), a connecting shaft 3102, a front rotating arm 3103, a stepping motor 3104, a rear rotating arm 3105, and a pneumatic gripper 3106. The connecting shaft 3102 is fixedly connected to the rotary lifting mechanism 3101. The front rotating arm 3103 is fixed on the connecting shaft 3102. The body of the stepping motor 3104 is fixed on the front rotating arm 3103. The rear rotating arm 3105 is connected to the rotating shaft of the stepping motor 3104 (or connected after passing through a speed reducer). The pneumatic gripper 3106 is fixed on the rear rotating arm 3105. The pneumatic gripper 3106 ventilates to contract the clamping end to clamp the test dish, and cuts off the air to open the clamping end to release the test dish. The stepping motor 3104 drives the rear rotating arm 3105 to rotate relative to the front rotating arm 3103. The rotary lifting mechanism 3101 drives the rear rotating arm 3105 and the front rotating arm 3103 to rotate or lift. The rotary lifting mechanism 3101 and the stepping motor 3104 can position the pneumatic gripper 3106 at the position of the nearest test dish in the test cavity 1310 and the position of the weighing pan 1802. With the lifting of the rotary lifting mechanism 3101 and the grasping function of the pneumatic gripper 3106, the test dish 1004 in the cavity is transferred to the weighing pan 1802 for weighing and then returned to its original position. Then, in cooperation with the rotary lifting mechanism 1006, the weighing of all test dishes can be completed. To reduce the operating space of the cup grasping mechanism 3100, at this time, the length dimensions of the rear rotating arm 3105 and the front rotating arm 3103 can only drive the pneumatic gripper 3106 to reach the test dish cup position closest to the grasping mechanism 3100.

[0118] The cup moving and weighing process in the third implementation method includes:

[0119] The rotary lifting mechanism 3101 rotates the front rotating arm 3103, and the stepping motor 3104 rotates the rear rotating arm 3105 to position the pneumatic gripper 3106 at the position of the nearest test dish in the test cavity 1310. The rotary lifting mechanism 3101 descends, and the pneumatic gripper 3106 clamps the test dish 1004. The rotary lifting mechanism 3101 rises. The rotary lifting mechanism 3101 rotates the front rotating arm 3103, and the stepping motor 3104 rotates the rear rotating arm 3105 to position the pneumatic gripper 3106 at the position of the weighing pan 1802. The rotary lifting mechanism 3101 descends, and the pneumatic gripper 3106 releases the test dish 1004. The rotary lifting mechanism 3101 rises, and the test dish 1004 falls on the weighing pan 1802 for weighing the test dish. After weighing is completed, reverse the operation to return the test dish. The rotary lifting mechanism 1006 rises, turns to the next test dish, then descends, and uses the rotary lifting mechanism 3101 to repeat the process of moving and placing the test dish to complete the weighing of all test dishes.

[0120] In a fourth alternative implementation, the rear swing arm 3105 and the front swing arm 3103 of the cup grasping mechanism 3100 are lengthened to appropriate lengths, enabling the pneumatic gripper 3106 to reach all the positions of the test dishes in the test chamber 1310. Without the need for the rotary lifting mechanism 1006, the grasping and weighing of the test dishes can be completed, as Figure 9 and Figure 13 shown.

[0121] Specifically, the process of moving the cup and weighing includes:

[0122] The rotary lifting mechanism 3101 rotates the front swing arm 3103, and the stepping motor 3104 rotates the rear swing arm 3105 to position the pneumatic gripper 3106 at the position of the first test dish in the test chamber 1310. The rotary lifting mechanism 3101 descends, the pneumatic gripper 3106 clamps the test dish 1004, the rotary lifting mechanism 3101 rises, the rotary lifting mechanism 3101 rotates the front swing arm 3103, and the stepping motor 3104 rotates the rear swing arm 3105 to position the pneumatic gripper 3106 at the position of the weighing pan 1802. The rotary lifting mechanism 3101 descends, the pneumatic gripper 3106 releases the test dish 1004, the rotary lifting mechanism 3101 rises, and the test dish 1004 falls onto the weighing pan 1802 for weighing the test dish. After weighing is completed, the reverse operation is performed to place the test dish back, and the rotary lifting mechanism 3101 is re-driven to position the next test dish, repeating the process of moving and placing the test dishes to complete the weighing of all test dishes. In this solution, the test dishes 1004 can be arbitrarily arranged on the 1005 cup tray without the need for a circular arrangement, resulting in higher space utilization.

[0123] In a fifth alternative implementation, the rotary drive mechanism of the cup moving mechanism 1700 is replaced with the cup moving mechanism 4100, as Figure 14 、 Figure 15 shown. At this time, the cup moving mechanism and the weighing mechanism are on a straight line, on one side of the test chamber, and the weighing mechanism is in the middle between the test chamber and the cup moving mechanism (as Figure 26 shown).

The sliding plate 4104 is slidably connected to the slide rail 4105 through the slider 4103, and the sliding plate 4104 is fixedly connected to the output end of the sliding cylinder 4106 through the connecting block. The sliding plate 4104 is provided with a bayonet for inserting under the rim of the test dish or is provided with clamping jaws (such as Figure 15 as shown).

[0126] In a sixth implementation mode, the cup moving mechanism and the weighing mechanism are on a straight line, on one side of the test chamber, and the weighing mechanism is in the middle between the test chamber and the cup moving mechanism (such as Figure 26 as shown).

[0127] Such as Figure 16 as shown, the linear drive mechanism 4100 includes: a rod-guided cylinder 4101 (i.e., the second linear drive mechanism), a linear drive mechanism 4108 (i.e., the third linear drive mechanism), a fixed plate 4102, and a sliding plate 4104. The fixed plate 4102 is rigidly connected to the output end of the rod-guided cylinder 4101. The body of the third linear drive mechanism 4108 is fixedly connected to the fixed plate 4102. The output end of the third linear drive mechanism 4108 is directly connected to the sliding plate 4104 or is connected to the sliding plate 4104 through a connecting member. The sliding plate 4104 is provided with a bayonet for inserting under the rim of the test dish or is provided with clamping jaws 4107 (such as Figure 17 as shown).

[0128] In a seventh implementation mode, the cup moving mechanism and the weighing mechanism are on the same side of the test chamber, and the weighing mechanism is in the middle between the test chamber and the cup moving mechanism (such as Figure 27 as shown).

[0129] Such as Figure 18 as shown, the cup moving mechanism 5100 includes: a rod-guided cylinder 5101 (i.e., the second linear drive mechanism), a transverse robotic arm 5102, a longitudinal robotic arm 5103, a probing arm 5104, and clamping jaws 5105. The output end of the rod-guided cylinder 5101 is fixedly connected to the transverse robotic arm 5102. The longitudinal robotic arm 5103 is perpendicular to and slidably connected to the transverse robotic arm 5102. The longitudinal robotic arm 5103 is perpendicular to and slidably connected to the probing arm 5104. The probing arm 5104 is fixedly connected to the clamping jaws 5105.

[0130] In the eighth alternative implementation, the weighing mechanism is arranged between the test chamber and the cup moving mechanism. The cup moving mechanism includes: a second linear driving mechanism, a transverse robotic arm, a longitudinal robotic arm, and a probing arm. The output end of the second linear driving mechanism is fixedly connected to the transverse robotic arm. The longitudinal robotic arm is perpendicular to and slidably connected to the transverse robotic arm. The longitudinal robotic arm is perpendicular to and slidably connected to the probing arm.

A cup tray for carrying the test dish is fixedly connected inside the test chamber, that is, the first rotary driving mechanism is not provided, as Figure 5 、 Figure 22 、 Figure 23 shown.

[0132] In this implementation, the cup moving mechanism can only adopt the Figure 11 and Figure 18 shown structures. When adopting the Figure 11 described structure, multiple test dishes can be arranged randomly. The cup moving mechanism and the weighing mechanism are on the same side of the test chamber, and their positions can be arranged randomly, as Figure 25 、 Figure 27 、 Figure 28 and Figure 29 shown; when adopting the Figure 18 structure, multiple test dishes can be arranged randomly. The cup moving mechanism and the weighing mechanism are on the same side of the test chamber, and the weighing mechanism is located in the middle between the test chamber and the cup moving mechanism, as Figure 26 、 Figure 27 shown.

[0133] In the tenth alternative implementation, as Figure 23 and Figure 24 shown, the upper cover assembly 2100 is movably linked to the test chamber body 1310 (which can be connected through a rotary hinge 2201).

The open cover cylinder 2202 is fixed on the bottom plate 1001 or the test chamber housing 1313.
