DETAILED DESCRIPTION

[0032] The specific embodiments of the utility model are described in detail below in combination with the drawings.

[0033] The existing automatic drying and weighing equipment has a drying cabin and a drying and weighing cabin in an up-down layout, in a laboratory environment with limited desktop space, the equipment occupies a large vertical space, and it is difficult to flexibly adapt to different desktop heights. Moreover, the up-down layout structure of the drying cabin and the drying and weighing cabin causes the center of gravity of the equipment to be high, when the equipment is placed on the desktop for use, the equipment is prone to shaking or even falling, affecting the drying and weighing operations in progress, and leading to inaccurate detection results. Figures 1-6 As shown in the drawings, the embodiment of the utility model proposes a drying and weighing detection equipment, aiming at optimizing the overall structure of the existing automatic drying and weighing equipment, reducing the height of the equipment, and being suitable for desktop use scenarios.

[0034] The drying and weighing detection equipment in the embodiment of the utility model connects the drying cabin to one side of the weighing cabin, forms a horizontal layout structure, effectively reduces the occupation of vertical space by the equipment, and facilitates the equipment to be placed more flexibly on desktops of different heights, improving the spatial adaptability of the equipment in a laboratory environment. At the same time, the overall center of gravity of the drying and weighing detection equipment is lower, and the equipment is more stable when placed on the desktop, greatly reducing the risk of shaking or falling of the equipment, ensuring the smooth progress of drying and weighing operations, and providing reliable protection for obtaining accurate detection results.

[0035] As shown in the drawings, Figure 1 A drying and weighing detection equipment includes a drying cabin 1 and a weighing cabin 2. The drying cabin 1 is connected to one side of the weighing cabin 2, and the interiors of the two form a connecting cavity. The connecting cavity is provided with a transfer component 3 and a partition assembly 4.

[0036] AsFigure 2 As shown in the figure, the drying chamber 1 is configured to form a gas drying circulation inside the drying chamber 1 by using a drying device, and to heat and dry the articles placed on the carriers 5 in the drying chamber 1.

[0037] As shown in the figure, the weighing chamber 2 is configured to cool the articles placed on the carriers 5, and to transfer the cooled articles to the weighing device 9 by using the transfer mechanism 8 for weighing, and then to send the articles back to the carriers 5. Figure 5

[0038] As shown in the figure, the transfer component 3 is arranged across the drying chamber 1 and the weighing chamber 2. The transfer component 3 is provided with a bearing platform 6 for mounting the carriers 5. The transfer component 3 is configured to drive the bearing platform 6 by using a power component, and to drive the carriers 5 to and from the drying chamber 1 and the weighing chamber 2. Figure 3

[0039] As shown in the figure, the partition assembly 4 is arranged between the drying chamber 1 and the weighing chamber 2. The partition assembly 4 is configured to form a partition for the connecting cavity, and to open with the action of the transfer component 3 to form a passage for the carriers 5 to and from the drying chamber 1 and the weighing chamber 2. Figure 3 Figure 4 As shown in the figure, the partition assembly 4 is arranged between the drying chamber 1 and the weighing chamber 2. The partition assembly 4 is configured to form a partition for the connecting cavity, and to open with the action of the transfer component 3 to form a passage for the carriers 5 to and from the drying chamber 1 and the weighing chamber 2.

[0040] As shown in the figure, the partition assembly 4 is arranged between the drying chamber 1 and the weighing chamber 2. The partition assembly 4 is configured to form a partition for the connecting cavity, and to open with the action of the transfer component 3 to form a passage for the carriers 5 to and from the drying chamber 1 and the weighing chamber 2.

[0041] According to some preferred embodiments of the present application, as shown in the figure, the transfer component 3 is mounted on the bottom of the connecting cavity through a base. The power component is mounted on the base. The bearing platform 6 is connected to the output end of the power component. For example, the power component can be selected as an electric cylinder structure or a structure of a servo motor driving a ball screw according to the needs. Figure 3

[0042] As shown in the figure, the partition assembly 4 includes a roller shutter 41, a roller shaft 42 and a roller shutter motor. Wherein, Figure 2 Figure 2 ​​​​​The winding motor is not shown. The winding shaft 42 is installed at the top of the connecting cavity. The roller shutter 41 is wound on the side wall of the winding shaft 42. The output end of the winding motor is connected to the winding shaft 42. The winding shaft 42 is installed at the top of the connecting cavity, and the roller shutter 41 is wound on the side wall of the winding shaft 42. This design does not occupy additional horizontal space, and makes the best use of vertical space in the limited connecting cavity. Compared with the translational or rotational partition structure, the roller shutter 41 partition structure occupies less space when it is retracted, making the space layout between the drying chamber 1 and the weighing chamber 2 more compact and reasonable.

[0043] By controlling the winding motor to drive the winding shaft 42 to rotate forward and reverse, the winding and unwinding of the roller shutter 41 can be realized, which is convenient for integration with the overall control system of the equipment. Only by issuing an instruction at the control terminal, the partition assembly 4 can accurately act according to the preset program. For example, when the transfer component 3 drives the carrier 5 to move back and forth between the two chambers, the roller shutter 41 is automatically opened and closed, reducing manual intervention and improving the automation degree and working efficiency of the equipment.

[0044] As shown in Figure 2 , the bottom end of the roller shutter 41 is connected with a counterweight beam 43. The counterweight beam 43 increases the weight of the bottom of the roller shutter 41, making the roller shutter 41 more stable during deployment and retraction. When the winding motor drives the winding shaft 42 to wind and unwind the roller shutter 41, the counterweight beam 43 can effectively reduce the shaking and deviation of the roller shutter 41 caused by uneven weight distribution or external factors such as air flow and vibration, ensuring that the roller shutter 41 always runs smoothly along the predetermined track, avoiding problems such as jamming and skewing during movement.

[0045] In addition, when the roller shutter 41 is lowered to form a partition, the counterweight beam 43 tightly adheres to the bottom of the connecting cavity by its own gravity, which can better fill the gap between the roller shutter 41 and the bottom, and enhance the sealing between the drying chamber 1 and the weighing chamber 2. In this way, the leakage and exchange of gas and heat between the two chambers are effectively prevented, which is conducive to maintaining the stability of the environment in each chamber.

[0046] In order to further improve the drying effect of the drying chamber 1, as shown in Figure 2 , an air inlet channel 11 and a blast heating channel 12 are arranged inside the drying chamber 1. The air inlet of the air inlet channel 11 is connected with a fresh air fan 13. The side wall of the air inlet channel 11 is provided with a fresh air outlet 14. The air inlet of the blast heating channel 12 is connected with a blast fan 15. The outlet of the blast fan 15 is provided with a heater 16. The side wall of the blast heating channel 12 is provided with a hot air outlet 17.

[0047] As shown in Figure 2As shown, the fresh air fan 13 introduces fresh air from the outside through the air inlet channel 11 to continuously provide sufficient air source for the drying process. At the same time, the air blower 15 cooperates with the heater 16 to generate high-temperature hot air in the air blowing and heating channel 12, and the hot air is sent into the drying chamber 1 through the hot air outlet 17. The fresh air and the high-temperature hot air cooperate with each other to accelerate the flow and circulation of the air in the chamber, so that the heat can be transferred to the dried goods more quickly, greatly shortening the drying time and improving the overall drying efficiency.

[0048] As shown in the drawings, Figure 2 The fresh air outlet 14 on the air inlet channel 11 and the hot air outlet 17 on the air blowing and heating channel 12 are reasonably distributed on the side wall of the drying chamber 1, so that fresh air and high-temperature hot air can enter the chamber from different positions to form a complex and uniform air flow field. In this way, each part of the dried goods can fully contact the hot air, avoiding local overheating or overcooling, ensuring the uniformity of the temperature in the drying chamber 1, thereby improving the drying quality and ensuring the consistency of the drying effect of the goods.

[0049] According to some preferred embodiments of the present application, as shown in the drawings, Figure 2 The air inlet channel 11 and the air blowing and heating channel 12 are arranged vertically. The vertically arranged air inlet channel 11 and air blowing and heating channel 12 make the fresh air and high-temperature hot air intersect in a vertical direction when entering the drying chamber 1. In this way, the fresh air and high-temperature hot air can be mixed more quickly and more fully. Compared with parallel or other angle layout, vertical layout can form a mixed air flow with uniform temperature in a short time, providing a better drying environment for the dried goods.

[0050] As shown in the drawings, Figure 2 The inner wall of the drying chamber 1 is provided with an exhaust and moisture suction port 7. The exhaust and moisture suction port 7 is used to timely exhaust the humid air containing a large amount of water vapor, effectively reduce the humidity in the chamber, maintain the relative humidity of the drying environment within a suitable range, ensure that the dried goods can continuously and efficiently evaporate water, and avoid affecting the drying efficiency due to humidity saturation.

[0051] As shown in the drawings, Figure 5 The transfer mechanism 8 is arranged on one side of the bracket 5. The transfer mechanism 8 is used to transfer the cooled goods to the weighing device 9 for weighing, and then send them back to the bracket 5. The specific structure of the bracket 5 is similar to the tray structure for carrying test dishes disclosed in the patent document CN221570997U, which will not be described here. The specific structure of the transfer mechanism 8 is similar to the structure of the transfer mechanism disclosed in the patent document CN221570997U, which will not be described here.

[0052] In order to further improve the cooling efficiency of the goods to be weighed in the weighing chamber 2, as shown in the drawings, Figure 6As shown, the weighing cabin 2 is provided with a gas circulation device. The gas circulation device comprises an air inlet channel 21, a treatment chamber 22 and a power fan 23. The air inlet channel 21 is arranged on the inner wall of the weighing cabin 2. The air inlet channel 21 is connected with the treatment chamber 22. The end of the air inlet channel 21 is provided with an air inlet 24. The air inlet channel 21 is configured to guide the gas in the weighing cabin 2 into the treatment chamber 22 through the air inlet 24.

[0053] As shown, the power fan 23 is installed in the treatment chamber 22. The side wall of the treatment chamber 22 is provided with an air outlet 25. The power fan 23 is configured to suck the gas in the weighing cabin 2 from the air inlet 24 into the treatment chamber 22 through the air inlet channel 21, and discharge the gas from the air outlet 25. Figure 6

[0054] In the weighing cabin 2, the gas itself is in a state of relative stillness or slow flow, and it is difficult to form an effective circulation spontaneously. The suction force and pressure difference generated by the operation of the power fan 23 are the key driving force for gas circulation. Through the suction effect, the power fan 23 sucks the gas in the weighing cabin 2 from the air inlet 24 of the air inlet channel 21, and then enters the treatment chamber 22 through the air inlet channel 21. Then, the fan discharges the gas entering the treatment chamber 22 from the air outlet, which continuously circulates, so that the gas in the weighing cabin 2 can be continuously updated to ensure smooth circulation of the gas.

[0055] For example, the power fan 23 can select a centrifugal fan or an axial flow fan according to the needs of the drying weighing detection device for gas circulation.

[0056] As shown, the treatment chamber 22 is provided with a cold source component 26. The cold source component 26 is configured to cool and dehumidify the gas entering the treatment chamber 22. The temperature of the gas is lowered by using the cold source component 26, so that the water vapor in the gas is liquefied by the cold. Figure 6 For example, the cold source component 26 can select a compressor refrigeration system or a semiconductor refrigeration fin type refrigeration device. Considering the overall structure of the constant weight weighing system and the limited internal space in the treatment chamber 22, the cold source component 26 is preferably a semiconductor refrigeration fin type refrigeration device.

[0057] As shown, a heating component 27 is arranged between the cold source component 26 and the power fan 23. The heating component 27 is used to heat the low-temperature gas to realize accurate control of the temperature of the gas, and ensure that the temperature of the gas entering the closed cabin is stable near the set value, reducing the influence of temperature fluctuations on the mass measurement of the object. For example, the heating component 27 can select a resistance wire heater or a ceramic heater according to actual needs.
