[0046] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] In the prior art, in order to ensure the accuracy of the results of the adsorption tube after being detected by a thermal desorption instrument and a gas chromatography-mass spectrometry detection instrument, a certain amount of substance is loaded in the adsorption tube in advance. After the adsorption tube passes the detection, the accuracy of the detection result is determined again based on the remaining amount of substance. The means of loading substances in the adsorption tube requires manual connection of several adsorption tubes to the loading pump in turn, and waiting for the loading to be completed before replacing the next adsorption tube, which is time-consuming and laborious.

[0048] In order to solve the above technical problems, in at least one embodiment, a multi-channel adsorption tube material loading device is provided, comprising: a loading base 1, on one side of which an upper end surface is provided with a loading pump 11; wherein the output end of the loading pump 11 is connected to a loading main pipe 12, and the input end thereof is connected to a material carrying box; and a plurality of shunt pipes 13 are evenly arranged on the loading main pipe 12; an auxiliary mechanism 2, arranged on one side of the loading main pipe 12, on which a plurality of placement grooves 25 are opened to correspond to the respective shunt pipes 13; wherein the placement grooves 25 are suitable for accommodating adsorption tubes 4; and a pushing unit, arranged on one side of the placement grooves 25, suitable for synchronously pushing the adsorption tubes 3 to be connected to the respective shunt pipes 13 when starting;

[0049] By providing an auxiliary mechanism, several adsorption tubes can be accommodated at the same time, and cooperate with several shunt tubes provided on the loading main pipe, the two are matched one by one, and the pushing unit is driven at the same time to push several adsorption tubes at the same time until they are inserted into the shunt tubes corresponding to each adsorption tube to load the material. Compared with the prior art of manual hand-held loading one by one, the work efficiency is improved and manpower is saved.

[0050] In some embodiments, the operator sequentially places a plurality of adsorption tubes 4 in the placement slots 25 provided on the placement seats 22. Figure 1It can be seen that the placement slots 25 correspond one-to-one to each branch pipe 13, and each adsorption tube 4 is connected to each branch pipe 13 through a pushing unit, and the two are in the same horizontal plane. The loading pump 11 is started to extract the material and introduce it into the loading main pipe 12, and it flows out through the branch pipes 13 on the loading main pipe 12, and then introduced into the adsorption tube 4 (in order to monitor the amount of material loaded in each adsorption tube 4, a flow detector can be added to each branch pipe 13 to obtain the content of the material entering each adsorption tube 4. This is a prior art and will not be elaborated in this application).

[0051] In some embodiments, after each adsorption tube 4 is placed in the placement slot 25, the motor 20 is started and rotated forward by a certain angle, and its output end drives the turntable 201 to rotate by a certain angle. Figure 2 As shown, the two ends of the driving rod 202 are respectively connected to the surface of the turntable 201 and the outer wall bearing of the connecting rod 231. Therefore, when the turntable 201 rotates forward, the driving rod 202 drives the connecting rod 231 and the push plate 23 connected to the top of the connecting rod 231 to move horizontally, thereby driving the hollow push rods 24 fixed on the push plate 23 to move along the axial direction of the placement groove 25 until the adsorption tube 4 is pushed to connect with each diversion tube 13, so that the material in the diversion tube 13 is loaded into the adsorption tube 4, and several adsorption tubes 4 are loaded simultaneously, thereby improving work efficiency and avoiding manual holding of the adsorption tube 4 for loading, saving manpower.

[0052] In some embodiments, with long-term use, stains will remain in the placement groove 25. Since the placement groove 25 is opened according to the diameter of the adsorption tube 4, the diameter of the placement groove 25 is small. If the stains are directly wiped manually, it is difficult to completely remove them. At the same time, the operator's hand will inevitably contact the shunt tube 13, causing the shunt tube 13 to move, affecting the subsequent connection with the adsorption tube 4. To solve this problem, Figure 3As shown, a cleaning cylinder 30 is connected to the end bearing on the loading base 1, and a driven shaft 32 arranged at the bottom thereof is connected to the output end of the motor 20 via a belt 31, and an overrunning clutch is arranged between the driven shaft 32 and the screw rod 33, that is, when the motor 20 rotates forward, the driven shaft 32 is driven to rotate forward via the belt 31, and the screw rod 33 is stationary at this time. When the placement groove 25 needs to be cleaned, the motor 20 is reversed to drive the driven shaft 32 to reverse, and the screw rod 33 rotates accordingly, and meshes with the piston member 34 arranged inside the cleaning cylinder 30. A slide groove is arranged on the inner wall of the cleaning cylinder 30, and a slider is arranged on the outer wall of the piston member 34. Through the cooperation between the slider and the slide groove , guide the piston member 34 so that it slides upward in the cleaning cylinder 30 under the meshing with the screw rod 33, and discharges the cleaning liquid in the cleaning cylinder 33 through the discharge pipe 35 and the cleaning pipes 36 connected to the discharge pipe 35. The cleaning pipe 36 is made of a flexible material, and the cleaning pipe 36 passes through the push plate 23 and is located inside the hollow push rods 24 (the hollow push rods 24 are hollowed out at one end facing the shunt pipe 13). That is, at this time, the cleaning liquid is discharged from the inside of the hollow push rods 24 into the placement groove 25. With the reverse rotation of the motor 20, the hollow push rods 24 are driven to slide back and forth in the placement groove 25 to remove the stains in the placement groove 25.

[0053] To sum up, by providing an auxiliary mechanism, several adsorption tubes can be accommodated at the same time, and cooperate with several diversion tubes set on the loading main pipe, the two are matched one by one, and the pushing unit is driven at the same time to push several adsorption tubes at the same time until they are inserted into the diversion tubes corresponding to each adsorption tube to load the material. Compared with the prior art of manual hand-held loading one by one, work efficiency is improved and manpower is saved.
