Description

Technical Field

[0001] This utility model relates to the field of moisture determination technology for chewable tablets, and in particular to a device for determining the moisture content of chewable tablets. Background Technology

[0002] In the field of moisture determination of chewable tablets, thermogravimetric analysis is widely used due to its ease of operation, but its accuracy is highly dependent on sample pretreatment and heating efficiency.

[0003] Existing technologies often employ a chewable tablet moisture determination device, such as the one disclosed in CN219142552U, to identify the moisture content of chewable tablets. Although this device agitates the chewable tablets using a stirring mechanism, the stirring plate only agitates the surface sample and cannot break down the dense chewable tablet structure. The internal moisture is physically trapped and difficult to release. Moreover, the dual-heating-source discrete heating source used in this device employs a design with a top halogen lamp combined with a bottom electric heating plate, resulting in a single direction of heat radiation. This leads to uneven heating of the powdered sample, insufficient moisture evaporation, and the possibility of excessively long evaporation times or even incomplete evaporation. Utility Model Content

[0004] The purpose of this invention is to solve the problem of insufficient evaporation in the existing technology when measuring the moisture content of chewable tablets, and to propose a chewable tablet moisture measuring device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A chewable tablet moisture measuring device includes a mounting base and an assembly box mounted on the mounting base. The assembly box has concentrically distributed circular grooves and an annular outer cavity. A circular handle cover is assembled and connected to the assembly box. A crushing mechanism for crushing chewable tablets to obtain chewable tablet powder is installed in the circular grooves. A heating mechanism for drying the chewable tablet powder is provided in the annular outer cavity. A detection mechanism for detecting whether the chewable tablets contain moisture is fixedly connected to the circular handle cover and mounted on the mounting base, and is used in conjunction with the heating mechanism.

[0007] Preferably, the assembly box has a circular groove opening, and the circular handle cover controls the opening and closing of the circular groove through a threaded connection with the assembly box.

[0008] Preferably, the crushing mechanism includes a cross-shaped fixing rod fixedly installed on the inner wall of the upper end of the circular groove. A drive motor is fixedly mounted on the cross-shaped fixing rod. The output end of the drive motor is fixedly connected to a transmission shaft rotatably disposed at the lower end of the circular groove. A first flywheel is fixedly installed on the upper end of the transmission shaft. A base is provided on the edge of the first flywheel. A first rotating shaft is mounted on the base with a pin. A crushing blade is fixedly installed on the first rotating shaft. A traction rod is rotatably connected to the first rotating shaft. A second rotating shaft rotatably mounted on the upper end of the traction rod is rotatably connected to the first flywheel. A drive turntable rotatably connected to the second rotating shaft is rotatably installed on the transmission shaft. A second flywheel is fixedly connected to the lower end of the transmission shaft. A serrated blade is fixedly disposed on the second flywheel. A serrated groove that engages with the serrated blade is provided at the point where the inner wall of the circular groove is flush with the second flywheel.

[0009] Preferably, the drive turntable has an insertion groove on its edge, a retraction groove on the inner wall of the circular groove, and a rod for fixing the drive turntable is provided between the insertion groove and the retraction groove.

[0010] Preferably, the heating mechanism includes a heating power supply fixedly mounted on the mounting base, the heating power supply being fitted with wires, a leakage current protector being installed on the wires, and a heating wire being provided inside the annular outer cavity.

[0011] Preferably, the heating mechanism further includes an insulating protective sleeve for securing the wiring.

[0012] Preferably, the detection mechanism includes a circular through hole in the circular handle cover 3, an air intake valve is fixedly installed on the circular through hole, a conveying pipe for transmitting water vapor is fixedly fitted on the air intake valve, and a limiting protrusion is evenly arranged around the end of the conveying pipe.

A rotating sleeve for detaching and connecting the conveying pipe and the condenser bottle is provided on the condenser bottle.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This utility model utilizes a drive motor to drive a transmission rod to rotate, which in turn drives the crushing blades on the first flywheel to rotate. The insertion rod controls the rotation of the drive turntable, thereby controlling the deflection angle of the blades to crush the chewing tablets more thoroughly. At the same time, with the support of the first flywheel, the second flywheel makes the grinding efficiency of the serrated blades and serrated grooves even higher.

[0015] 2. This utility model uses a heating power supply to heat the heating wire under the safety protection of a high-temperature resistant, short-circuit-proof wiring sheath and a leakage protection device, so that the chewing tablet powder is fully heated. At this time, the evaporated gas is drawn into the condenser bottle through the suction valve for observation, thereby clearly knowing whether the chewing tablet contains water. This greatly improves the efficiency of the test and the safety of the operation. Attached Figure Description

[0025] A crushing mechanism 6 for crushing chewable tablets to obtain chewable tablet powder is installed inside the circular groove 4. The crushing mechanism 6 includes a cross-shaped fixing rod 61 fixedly installed on the inner wall of the upper end of the circular groove 4. The center of the cross-shaped fixing rod 61 is in the same direction as the circular groove, and the middle part of the cross-shaped fixing rod is a rectangular plate that can be used to fix and install a motor. A drive motor 62 is fixedly mounted on the cross-shaped fixing rod 61. The output end of the drive motor 62 is fixedly connected to a transmission shaft 63 rotatably set at the lower end of the circular groove 4. The bottom end of the transmission shaft 63 is rotatably installed at the bottom end of the circular groove 4 for adjusting the transmission shaft 62. 3. A first flywheel 64 is fixedly installed on the upper end of the drive shaft 63. The distance between the first flywheel 64 and the inner wall of the circular groove 4 is relatively far, which facilitates the crushing of large chewable tablets. A base 65 is provided on the edge of the first flywheel 64. Two bases 65 are symmetrically arranged. A pin is provided in the middle of the base 65. A first rotating shaft 68 is installed on the pin in the base 65. A crushing blade 66 is fixedly installed on the first rotating shaft 68. The crushing blade 66 is a wedge-shaped blade with a V-shaped design to concentrate pressure, easily cut into the tablet, and reduce fragmentation. The crushing blade 66 can be made of 304 or 316L stainless steel with high hardness, which can keep the crushing blade sharp for a long time and has excellent corrosion resistance and resistance to repeated disinfection by cleaning agents. The first rotating shaft 68 is rotatably connected to a traction rod 67. The upper end of the traction rod 67 is rotatably connected to a second rotating shaft 69 rotatably installed on the first flywheel 64.

The serrated groove 615 can be made of ultra-high molecular weight polyethylene. The wear resistance of ultra-high molecular weight polyethylene is 7 times that of carbon steel. It also has excellent self-lubricating properties, prevents powder from sticking, and has an impact strength of ≥100kJ / m². It can withstand repeated impacts and can be processed into complex tooth groove structures at low cost.

[0026] A heating mechanism 7 for drying chewable tablet powder is provided inside the annular outer cavity 5. The heating mechanism 7 includes a heating power supply 75 fixedly mounted on the mounting base 1. The heating power supply 75 is fixedly fitted with a wire 71. A leakage protection device 72 is installed on the wire 71. An electric heating wire 74 is provided inside the annular outer cavity 5.

The insulating protective sleeve 73 can be made of PTFE composite fiberglass sleeve, which can withstand instantaneous temperature of 260°C and is resistant to strong acids and alkalis.

[0028] A detection mechanism 8, which is fixedly connected to the circular handle cover 3 and mounted on the mounting base 1, is used to detect whether the chewable tablets contain water in conjunction with the heating mechanism 7. The detection mechanism 8 includes a circular through hole 81 in the circular handle cover 3, an air intake valve 82 fixedly installed in the circular through hole 81, and a conveying pipe 83 for transmitting water vapor fixedly fitted on the air intake valve 82. Four limiting protrusions 84 are evenly arranged around the end of the conveying pipe 83. A condenser bottle 86 with a temperature of -20℃ to -5℃ is set on the mounting base 1. Four limiting grooves 87 are evenly spaced around the condenser bottle 86 to limit the conveying pipe 83. A rotating sleeve 85 is set on the condenser bottle 86 for connecting and disconnecting the conveying pipe 83 from the condenser bottle 86. The inner ring of the rotating sleeve 85 has four grooves for cooperating with the protrusions and limiting grooves 87 on the conveying pipe 83 to achieve quick assembly and disassembly.

[0029] It should be noted that the specific models and specifications of the drive motor 62, leakage current protector 72, wire 71, and heating power supply 75 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt existing technology in this field, so they will not be elaborated here.

[0030] The functional principle of this utility model can be explained through the following operation methods:

[0031] Place the chewing tablet into the circular groove 4;

[0032] The drive motor 62 rotates, driving the transmission shaft 63. The transmission shaft 63 drives the drive turntable 616 and the first flywheel 64 to rotate. By manually adjusting the insertion rod 611 within the insertion groove 610 and retraction groove 612, the drive turntable 616 is fixed in a suitable position and then released. Under the adjustment of the drive turntable 616, the second rotating shaft 69 rotates, causing the traction rod 67 to deflect, which in turn causes the first rotating shaft 68 to rotate, causing the crushing blade 66 to shift. At the same time, the rotation of the first flywheel 64 drives the shifted crushing blade 66 to crush the chewing pieces. The crushed chewing pieces fall onto the second flywheel 613. Driven by the rotation of the second flywheel 613, the crushed chewing pieces are ground by the serrated blade 614 and serrated groove 615, thus grinding the chewing pieces into powder and increasing the grinding rate.

[0033] At this time, the heating wire 74 is energized and heated, causing the temperature inside the annular outer cavity 5 to gradually rise and heat and evaporate the chewing tablet powder in the inner circular groove 4. The suction valve 82 draws the evaporated water vapor into the delivery pipe 83 through the circular through hole 81, and delivers it to the condenser bottle 86 through the delivery pipe 83 to cool it down and check for water droplets, thereby improving the detection efficiency.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
