Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0029] like Figure 1 and Figure 2 As shown, the present application provides a milk powder sampling device, comprising: a sampling unit 1, a detection table 2, a purification unit 3 and a drying and disinfection unit 4.

[0030] The sampling unit 1 includes a main rotating shaft 110, a first motor 120, a first gear 130, a second gear 140, a fixed rod 150, a telescopic cylinder 160, a connecting rod 170, a sampling tube 180 and a sampling tube cover 190. The output end of the first motor 120 is connected with an output shaft, the first gear 130 is fixedly sleeved on the output shaft, the second gear 140 is sleeved on the main rotating shaft 110, the first gear 130 is meshed and connected with the second gear 140, the fixed rod 150 is arranged on the upper part of the main rotating shaft 110, the length direction of the fixed rod 150 is perpendicular to the main rotating shaft 110, one end of the fixed rod 150 is connected to the base end of the telescopic cylinder 160, the telescopic end of the telescopic cylinder 160 is connected to one end of the connecting rod 170, the bottom of the connecting rod 170 is fixedly connected with the sampling tube 180, and the sampling tube cover 190 is movably connected to the lower end of the sampling tube 180.

[0031] The detection table 2 , purification unit 3 , drying and disinfection unit 4 are arranged around the main rotating shaft 110 , and the detection table 2 , purification unit 3 , drying and disinfection unit 4 are arranged in sequence along the trajectory formed by the sampling tube 180 rotating around the main rotating shaft 110 .

[0032] Specifically, the powder sampling device in the present application includes: a sampling unit 1, a testing table 2, a purification unit 3 and a drying and disinfection unit 4. The sampling unit 1 is used to sample the milk powder in the conveying device. After the sampling unit 1 completes the sampling, the milk powder in the sampling unit 1 is placed on the testing table 2 by rotating, for subsequent quality testing of the milk powder. After the sampling unit 1 places the obtained milk powder sample on the testing table 2, it rotates again to the top of the purification unit 3. The purification unit 3 purifies the sampling port on the sampling unit 1 to prevent the residual milk powder on the sampling unit 1 from mixing with the milk powder sampled next time, so that the quality testing of the milk powder is more rigorous and the data is more reliable. The drying and disinfection unit 4 disinfects and dries the purified sampling unit 1 to prevent the residual detergent on the sampling unit 1 from affecting the quality testing of the milk powder.

[0033] The sampling unit 1 includes a main rotating shaft 110, a first motor 120, a first gear 130, a second gear 140, a fixing rod 150, a telescopic cylinder 160, a connecting rod 170, a sampling tube 180 and a sampling tube cover 190. The output end of the first motor 120 is connected to an output shaft. The first motor 120 provides power to drive the output shaft to rotate. At the same time, the output shaft drives the first gear 130 to rotate. The first gear 130 drives the second gear 140 meshing therewith to rotate. The second gear 140 drives the main rotating shaft 110 to rotate. The arrangement of the main rotating shaft 110, the first motor 120, the first gear 130 and the second gear 140 is used to rotate the direction of the sampling unit 1, so that the sampling unit 1 can rotate and switch between the milk powder conveying device, the detection table 2, the purification unit 3 and the drying and disinfection unit 4, so as to realize the sampling of milk powder, the cleaning, drying and disinfection of the sampling unit 1, so that the sampling unit 1 can continuously perform sampling.

[0034] The fixing rod 150 is disposed on the upper part of the main rotating shaft 110, and is used to connect the main rotating shaft 110 and the sampling barrel 180. One end of the fixing rod 150 is connected to the base end of the telescopic cylinder 160, and the telescopic end of the telescopic cylinder 160 is connected to one end of the connecting rod 170, and the bottom of the connecting rod 170 is fixedly connected with the sampling barrel 180. Through the extension and contraction of the telescopic cylinder 160, the connecting rod 170 can be raised and lowered, thereby driving the sampling barrel 180 to be raised and lowered.

[0035] During the sampling process, the first motor 120 is first turned on, and the first motor 120 provides power to drive the output shaft to rotate. At the same time, the output shaft drives the first gear 130 to rotate, the first gear 130 drives the second gear 140 to rotate, and the second gear 140 drives the main shaft 110 to rotate. The main shaft 110 drives the sampling barrel 180 to rotate above the milk powder conveying device through the fixed rod 150, that is, the first motor 120 is turned off. The telescopic cylinder 160 is turned on to extend or shorten the telescopic cylinder 160 so that the bottom of the sampling barrel 180 contacts the milk powder, and then the sampling barrel cover 190 is opened to open the lower end of the sampling barrel 180, and the telescopic cylinder 160 is continued to be opened to extend, and the sampling barrel 180 is inserted into the milk powder pile, so that the milk powder enters the sampling barrel 180. After the sampling is completed, the sampling barrel cover 190 is rotated to close the lower end of the sampling barrel 180, and the telescopic cylinder 160 is controlled to rise to a preset height to complete the preliminary sampling of the milk powder. After the preliminary sampling is completed, the first motor 120 is started again, so that the main shaft 110 continues to rotate, driving the sampling barrel 180 to rotate around the main shaft 110 to the top of the detection table 2, and the milk powder is poured onto the detection table 2 by opening the sampling barrel cover 190. The first motor 120 is started again, so that the main shaft 110 continues to rotate to the top of the purification unit 3, and the purification unit 3 cleans the sampling barrel 180 to prevent milk powder from remaining on the sampling barrel 180. After the cleaning is completed, the first motor 120 is started again, so that the main shaft 110 continues to rotate, driving the sampling barrel 180 to rotate around the main shaft 110 to the drying and disinfection unit 4 to dry and disinfect the sampling barrel 180, and obtain a dry and clean sampling barrel 180. At this time, a complete milk powder sampling process is completed, and the first motor 120 is continued to be turned on to perform the next sampling. This arrangement greatly reduces the input of human labor and improves the degree of automation of sampling. At the same time, it avoids the spillage of milk powder during the sampling process, making the milk powder sampling process cleaner and more stable.

[0036] The detection table 2, purification unit 3, drying and disinfection unit 4 are arranged around the main shaft 110, and the positions of the detection table 2, purification unit 3, drying and disinfection unit 4 are arranged in sequence along the trajectory formed by the rotation of the sampling cylinder 180 around the main shaft 110. In this way, only by the rotation of the main shaft 110, the sampling cylinder 180 is driven to rotate, thereby realizing the sampling of milk powder, the cleaning of the sampling cylinder 180, and the drying and disinfection, which is conducive to the convenience of milk powder sampling. At the same time, the structural design occupies a small area and saves space. Among them, the rotation angle of the main shaft 110 when passing through the detection table 2, purification unit 3, and drying and disinfection unit 4 in sequence is determined by the actual working conditions.

[0037] The present application realizes the rapid sampling of milk powder through the above scheme. The main shaft, the first motor, the first gear, and the second gear are arranged to rotate the direction of the sampling unit. The sampling barrel is driven to rotate by the rotation of the main shaft, so that the sampling barrel is rotated and switched between the milk powder conveying device, the detection table, the purification unit, and the drying and disinfection unit, so as to realize the sampling of milk powder, the cleaning, drying and disinfection of the sampling unit, so that the sampling unit can continuously perform sampling, which is conducive to the convenience of milk powder sampling. At the same time, the structural design occupies a small area and saves space. And such an arrangement greatly reduces the input of labor force, improves the degree of automation of sampling, and at the same time, avoids the spillage of milk powder during the sampling process, making the milk powder sampling process cleaner and more stable.

[0038] like Figure 3 As shown, optionally, the purification unit 3 includes a fixed platform 310 , a water spray pipe 320 and a water pump 330 , one end of the water spray pipe 320 vertically passes through the fixed platform 310 and is connected to the fixed platform 310 , and the other end of the water spray pipe 320 is connected to the water pump 330 .

[0039] The diameter of the water spray pipe 320 is smaller than the diameter of the sampling barrel 180 . When the sampling barrel 180 rotates to the top of the purification unit 3 , the water spray pipe 320 is aligned with the sampling barrel 180 in the vertical direction.

[0040] Specifically, the fixing platform 310 is used to fix the water spray pipe 320, and the water spray pipe 320 is used to spray water upward to clean the milk powder remaining on the sampling cylinder 180. When the purification unit is working, the first motor 120 is turned on to make the main shaft 110 continue to rotate, driving the sampling cylinder 180 to rotate around the main shaft 110 to the top of the purification unit 1, and the sampling cylinder 180 rotates to the top of the water spray pipe 320, and the water pump 330 is turned on to spray water into the sampling cylinder 180 through the water spray pipe 320, driving the milk powder attached to the sampling cylinder 180 to fall with the water flow, so as to achieve the purpose of cleaning the sampling cylinder 180. It can avoid the residual milk powder on the sampling cylinder 180, which leads to inaccurate quality detection data of the milk powder sampled next time, and ensure the accuracy of milk powder detection.

[0041] Among them, the diameter of the water spray pipe 320 is smaller than the diameter of the sampling tube 180, which is conducive to pushing the sampling tube 180 down through the telescopic cylinder 160, so that the water spray pipe 320 enters the interior of the sampling tube 180, thereby improving the cleaning efficiency of the water spray pipe 320 on the sampling tube 180.

[0042] Furthermore, a through hole is opened on the side wall of the water spray pipe 320, so that when cleaning the sampling tube 180, the end of the water spray pipe 320 and the through hole can spray water at the same time, further improving the cleaning efficiency of the sampling tube, saving sampling cycles, and improving the efficiency of milk powder sampling.

[0043] like Figure 4As shown, optionally, the drying and disinfection unit 4 includes an air blowing pipe 410, an electric heater 420 and an ultraviolet lamp group 430. The air blowing pipe 410 is vertically placed on a fixed frame 411, the outlet end of the air blowing pipe 410 is vertically upward, the inlet end of the air blowing pipe 410 is connected to a high-pressure gas tank 440, the electric heater 420 is sleeved on the outside of the air blowing pipe 410, and the ultraviolet lamp group 430 is surrounded and arranged on the upper part of the air blowing pipe 410.

[0044] Specifically, the high pressure gas tank 440 provides high pressure gas, and the fixing frame 411 is used to fix the blowing pipe 410 so that the outlet end of the blowing pipe 410 is vertically upward. The ultraviolet lamp group 430 is used to emit ultraviolet spectrum to perform ultraviolet disinfection on the sampling tube 180.

[0045] When the drying and disinfection unit 4 is working, the first motor 120 is turned on to make the main shaft 110 continue to rotate, driving the sampling barrel 180 to rotate around the main shaft 110 to the top of the air blowing pipe 410, and the high-pressure gas tank 440 is turned on to blow the high-pressure gas to the sampling barrel 180 through the air blowing pipe 410, and the water on the sampling barrel 180 is blown out while the ultraviolet disinfection is carried out. The electric heater 420 is used to heat the high-pressure gas, and the heated high-pressure gas can improve the efficiency of blowing off water and the drying efficiency of the sampling barrel 180.

[0046] Optionally, a gas regulating valve 412 is provided on the air blowing pipe 410 .

[0047] Specifically, the gas regulating valve 412 is used to adjust the amount of high-pressure gas entering the gas blowing pipe 410 .

[0048] like Figure 5 As shown, optionally, the sampling tube cover 190 is also connected to an automatic switch structure, which includes a bolt 191, a second motor 192, an active rod 193, a driven rod 194 and a rotating rod 195. One side of the sampling tube cover 190 is rotatably connected to the bottom of the sampling tube 180 via the bolt 191, and a rotating rod 195 is vertically connected to a side edge of the sampling tube cover 190 opposite to the bolt 191. The second motor 192 is arranged on the outside of the connecting rod 170, and the output end of the second motor 192 is vertically downward and connected to one end of the active rod 193. The other end of the active rod 193 is vertically connected to the driven rod 194, and the other end of the driven rod 194 is connected to an end of the rotating rod 195 away from the sampling tube cover 190.

[0049] Specifically, the automatic switch structure is used to open and close the sampling barrel cover 190. One side of the sampling barrel cover 190 is rotatably connected to the bottom of the sampling barrel 180 through a bolt 191, so that the sampling barrel cover 190 can rotate around the bolt 191, and the coverage rate of the sampling barrel cover 190 on the outlet of the sampling barrel 180 is controlled by adjusting the rotation angle of the sampling barrel cover 190.

[0050] The second motor 192 is turned on to drive the active rod 193 to rotate, and the active rod 193 drives the driven rod 194 to rotate in the horizontal plane, and then the driven rod 194 drives the rotating rod 195 to rotate around the active rod 193, so that the rotating rod 195 drives the sampling tube cover 190 to rotate around the bolt 191, thereby controlling the opening and closing of the sampling tube cover 190. This arrangement avoids the operation of manually opening and closing the sampling tube cover 190.

[0051] Optionally, the milk powder sampling device is also connected to a controller 5, which is electrically connected to the first motor 120, the telescopic cylinder 160, the water pump 330, the electric heater 420, the ultraviolet lamp group 430, the gas regulating valve 412 and the second motor 192 respectively.

[0052] Specifically, the controller 5 is used to start and stop the first motor 120 , the electric heater 420 , the ultraviolet lamp group 430 and the second motor 192 , and to start and stop and adjust the telescopic cylinder 160 , the water pump 330 and the gas regulating valve 412 .

[0053] Optionally, the UV lamp groups 430 are all directed toward the top of the air blowing tube 410 .

[0054] Specifically, the disinfection efficiency of the ultraviolet lamp group 430 on the sampling tube 180 is improved, and the utilization rate of the ultraviolet lamp is improved.

[0055] The technical solution of the present application is described in detail below with reference to specific embodiments.

[0056] The operation flow of the milk powder sampling device in this embodiment during specific operation is as follows:

[0057] During the sampling process, the first motor 120 is first turned on by the controller 5. The first motor 120 provides power to drive the output shaft to rotate. The output shaft drives the first gear 130 to rotate, the first gear 130 drives the second gear 140 to rotate, and the second gear 140 drives the main shaft 110 to rotate. The main shaft 110 drives the sampling barrel 180 to rotate above the milk powder conveying device through the fixed rod 150, that is, the controller 5 turns off the first motor 120. The controller 5 turns on the telescopic cylinder 160, so that the telescopic cylinder 160 is extended or shortened, so that the bottom of the sampling barrel 180 contacts the milk powder. Then the second motor 192 is turned on to rotate forward, driving the active rod 193 to rotate, the active rod 193 drives the driven rod 194 to rotate in the horizontal plane, and then the driven rod 194 drives the rotating rod 195 to rotate around the active rod 193, so that the rotating rod 195 drives the sampling barrel cover plate 190 to rotate around the bolt 191, and the sampling barrel cover plate 190 is opened.

[0058] Continue to open the telescopic cylinder 160 to extend it, and the sampling tube 180 is inserted into the milk powder pile, so that the milk powder enters the sampling tube 180. After the sampling is completed, the second motor 192 is turned on by the controller 5 to reverse, and the sampling tube cover 190 is rotated and closed, and the telescopic cylinder 160 is controlled to rise to a preset height to complete the preliminary sampling of the milk powder, and the preliminary sampling is ended.

[0059] When the purification unit is working, the first motor 120 is started again through the controller 5, so that the main shaft 110 continues to rotate, driving the sampling barrel 180 to rotate around the main shaft 110 to the top of the purification unit, and the sampling barrel 180 rotates to the top of the water spray pipe 320, and the water pump 330 is turned on to spray water into the sampling barrel 180 through the water spray pipe 320, driving the milk powder attached to the sampling barrel 180 to fall with the water flow, thereby achieving the purpose of cleaning the sampling barrel 180.

[0060] When the drying and disinfection unit 4 is working, the first motor 120 is turned on again by the controller 5, so that the main shaft 110 continues to rotate, driving the sampling barrel 180 to rotate around the main shaft 110 to the top of the air blowing pipe 410, and the high-pressure gas tank 440 is turned on. The high-pressure gas is blown to the sampling barrel 180 through the air blowing pipe 410, and the water on the sampling barrel 180 is blown out while the ultraviolet disinfection is carried out. The electric heater 420 is used to heat the high-pressure gas, and the heated high-pressure gas can improve the efficiency of blowing off the water. The opening of the gas regulating valve 412 is adjusted by the controller 5 to adjust the amount of high-pressure gas entering the air blowing pipe 410.

[0061] At this point, a complete milk powder sampling process is completed, and the first motor 120 is turned on again to perform the next sampling.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.

However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
