The sampling tube 21 is fixedly connected to the bottom wall of the conveying pipe 13 between the buffer hopper 11 and the finished product hopper 12, and the top end of the sampling tube 21 is communicated with the inside of the conveying pipe 13. The cyclone 25 is disposed at one side of the sampling tube 21, and a feed end of the cyclone 25 is communicated with a bottom end of the sampling tube 21. The collecting box 26 is located below the cyclone 25, and the discharge end of the cyclone 25 is directed towards the collecting box 26.

An air inlet pipe 751 is fixedly connected to the conveying pipe 13, one end of the air inlet pipe 751 is communicated with the air inlet part 81, and the other end of the air inlet pipe 751 is located in the conveying pipe 13. The air flow in the duct 13 can flow into the air inlet portion 81 through the air inlet duct 751 and then into the accommodating portion 82, the air flow can rotate the connection plate 72 so that the connection plate 72 abuts against the knocking block 73, and then the knocking block 73 can be rotated to a side away from the connection post 6 along with the rotation of the connection plate 72, and the first torsion spring 74 is further twisted. When the connecting plate 72 is separated from the contact with the knocking block 73, the first torsion spring 74 can enable the knocking block 73 to reversely rotate to reset, so that the knocking block 73 knocks the connecting post 6, and the connecting post 6 and the inner wall of the sampling tube 21 vibrate. The filter screen 752 is fixedly connected to one end of the air inlet pipe 751 located in the conveying pipe 13, and the aperture of the filter screen 752 is smaller than the particle size of the plastic particles, so that the plastic particles cannot enter the air inlet pipe 751, the accommodating groove 8 inside the sampling pipe 21 is not easy to be blocked, and smooth circulation of air flow is facilitated.
To enhance the pushing force of the air flow against the connection plate 72, the air inlet duct 751 is located at a side of the baffle 33 remote from the first fan 14. The baffle 33 is provided with a plurality of vent holes 331, and the aperture of the vent holes 331 is smaller than the particle diameter of the plastic particles. The baffle 33 is close to the side fixedly connected with direction shell 332 of air-supply line 751, and direction shell 332 is the toper setting, and the side that the direction shell 332 kept away from baffle 33 is provided with opening 3321. When the baffle 33 is in the vertical state, the opening 3321 on the guide housing 332 abuts against the end of the air inlet duct 751, thereby allowing the inside of the guide housing 332 to communicate with the air inlet duct 751. Therefore, during the sampling process, the plastic particles mixed in the air flow entering between the two side plates 32 can be blocked by the baffle plate 33, and the plastic particles fall into the sampling tube 21, while a part of the air flow can flow into the guide shell 332 through the vent hole 331, and then the air flow in the guide shell 332 can sequentially flow into the air inlet pipe 751, the air inlet part 81 and the accommodating part 82, so that the air flow flowing into the accommodating part 82 is increased, the thrust of the air flow to the connecting plate 72 is increased, the rotating speed of the connecting plate 72 is improved, the knocking frequency of the knocking block 73 to the connecting column 6 is improved, and the vibration effect of the sampling tube 21 is enhanced.
Referring to fig. 3, in order to reduce the possibility of clogging of the vent 331 on the baffle 33, a filter plate 9 is provided on a side of the baffle 33 remote from the guide housing 332, and a plurality of filter holes are provided on the filter plate 9, the diameter of the filter holes being smaller than the particle diameter of the plastic particles. The plastic particles that have entered between the side plates 32 can thus be blocked by the filter plate 9 and then fall down along the surface of the filter plate 9 into the sampling tube 21.
Referring to fig. 7 and 8, the top end of the filter plate 9 is hinged to the baffle plate 33, and the hinge axis of the filter plate 9 and the hinge axis of the baffle plate 33 are parallel. The top end of the baffle plate 33 is fixedly connected with a limiting plate 10, and a second torsion spring 16 is fixedly connected between the filter plate 9 and the baffle plate 33. Normally, the second torsion spring 16 is in a torsion state, so that the filter plate 9 abuts against the limiting plate 10, and the filter plate 9 is obliquely arranged at the moment.
Referring to fig. 8, 9 and 10, a connection assembly 17 is provided between the filter plate 9 and the baffle 33, and the connection assembly 17 includes a first magnet block 171 and a second magnet block 172. The first magnet 171 is fixedly connected to the bottom end of the filter plate 9, the second magnet 172 is fixedly connected to the bottom end of the baffle 33, and the magnetic poles of the first magnet 171 and the second magnet 172 are opposite in direction, so that the first magnet 171 and the second magnet 172 can be attracted to each other. When the first magnet piece 171 and the second magnet piece 172 are attracted to each other, both the filter plate 9 and the baffle 33 are in a horizontal state, at which time the second torsion spring 16 is further twisted.
Referring to fig. 4, 7 and 8, a first support rod 321 and a second support rod 322 for abutting against the filter plate 9 are fixedly connected to the side plate 32, and the first support rod 321 and the second support rod are arranged at intervals along the width direction of the conveying pipe 13. The first struts 321 are located on the lower side and the second struts 322 are located on the upper side. During sampling, the baffle 33 is in a vertical state, the filter plate 9 is in an inclined state, the second supporting rods 322 are positioned between the baffle 33 and the filter plate 9, and the filter plate 9 is abutted against the limiting plate 10 under the action of the second torsion spring 16. After sampling, when the baffle 33 rotates downwards, the baffle 33 drives the filter plate 9 to rotate, the filter plate 9 can be propped against the first supporting rod 321, and the first supporting rod 321 can limit the rotation of the filter plate 9 due to the fixed position of the first supporting rod 321, so that the filter plate 9 can rotate towards one side close to the baffle 33 relative to the baffle 33 along with the downward rotation of the baffle 33 until the baffle 33 rotates to a horizontal state, and at the moment, the first magnet 171 and the second magnet 172 are attracted to each other to temporarily and fixedly connect the filter plate 9 on the baffle 33.
When a resampling is required, the horizontal baffle 33 rotates upwards, and the baffle 33 drives the filter plate 9 to rotate together. The filter plate 9 will be against the second support rods 322 during rotation, and then the second support rods 322 limit the rotation of the filter plate 9, so that along with the rotation of the baffle plate 33, the filter plate 9 will rotate towards the side far away from the baffle plate 33 relative to the baffle plate 33, at this time, the first magnet block 171 and the second magnet block 172 are separated, the second torsion spring 16 enables the filter plate 9 to rotate rapidly and reset until the filter plate 9 abuts against the limiting plate 10, and thus the filter plate 9 can vibrate during the reverse rotation of the filter plate 9 and abutting against the limiting plate 10, so that plastic particles attached or blocked on the filter plate 9 vibrate down to clean the surface of the filter plate 9.
Wherein, notch 333 for the second strut 322 to pass through is provided on the baffle 33, so that the second strut 322 will not interfere with the baffle 33 during the rotation of the baffle 33, and the baffle 33 can smoothly rotate.
In addition, a flexible bag body (not shown in the figure) is arranged between the filter plate 9 and the baffle plate 33, and the bag body seals the area between the filter plate 9 and the baffle plate 33, so that in the process of blowing air into the sampling tube 21 by the second fan 27, plastic particles moving upwards along with air flow are not easy to enter the area between the filter plate 9 and the baffle plate 33, and therefore, the plastic particles in the sampling tube 21 can be conveyed into the conveying tube 13, and the influence of the part of plastic particles on the subsequent sampling process is reduced.
The second fan 27 may also be configured as an anion fan, so as to enhance the effect of removing static electricity from the plastic particles, so that the plastic particles are not easily attached to the inner wall of the sampling tube 21, thereby facilitating the enhancement of the cleaning effect on the inner wall of the sampling tube 21.
The implementation principle of the plastic particle online sampling system of the embodiment of the application is that the produced plastic particles fall into the buffer hopper 11, the plastic particles in the buffer hopper 11 enter the conveying pipe 13 under the action of the rotary valve 15, the first fan 14 is in a working state, and the first fan 14 blows air into the conveying pipe 13, so that the plastic particles in the conveying pipe 13 can be driven to move, and the plastic particles can move into the finished product hopper 12 through the conveying pipe 13.
In the initial state, the baffle 33 is in a horizontal state, the filter plate 9 is parallel to the baffle 33, the wind shielding block 4 is positioned below the avoidance hole 131, and the first valve body 22, the second valve body 23 and the third valve body 24 are all in a closed state. When sampling is required, the first fan 14 is still in an operating state, and plastic particles in the conveying pipe 13 are continuously conveyed. The second motor 5 drives the windshield block 4 to rotate upwards so that the windshield block 4 is positioned in the conveying pipe 13, and the first motor 34 drives the baffle 33 to rotate upwards until the baffle 33 rotates to a vertical state, and the filter plate 9 is in an inclined state. During the upward rotation of the filter plate 9, plastic particles adhering or clogging the filter plate 9 can be vibrated down.
The first valve body 22 and the third valve body 24 are opened, the second fan 27 is started, the second fan 27 blows air into the sampling tube 21, and the vibrated plastic particles are conveyed into the conveying tube 13. Meanwhile, a part of wind in the sampling tube 21 can pass through the filtering holes of the filter plate 9 and the ventilation holes 331 of the baffle plate 33 and then enter the guide shell 332, then sequentially flow into the air inlet pipe 751, the air inlet part 81 and the accommodating part 82, the wind flowing into the accommodating part 82 can enable the connecting plate 72 to rotate, the connecting plate 72 pushes the knocking block 73 to rotate, when the knocking block 73 is separated from contact with the connecting plate 72, the knocking block 73 reversely rotates to reset and knock the connecting column 6, so that the connecting column 6 and the inner wall of the sampling tube 21 vibrate, plastic particles attached to the inner wall of the sampling tube 21 vibrate, and the vibrated plastic particles are conveyed into the conveying tube 13 by wind blown out by the second fan 27.
After the cleaning of the inner wall of the top end of the sampling tube 21 is completed, the wind shielding block 4 rotates downwards to the lower part of the avoidance hole 131, the second fan 27 stops running, the third valve body 24 is closed, the second valve body 23 is opened, plastic particles in the conveying tube 13 can enter the area between the two side plates 32 and then are blocked by the filter plate 9, the plastic particles fall into the sampling tube 21, the plastic particles in the sampling tube 21 enter the cyclone separator 25 again, and the cyclone separator 25 can separate the plastic particles in the air flow, so that the plastic particles fall into the collecting box 26 at the bottom end of the cyclone separator 25, and samples are collected.
After the desired amount of plastic particles are collected in the collection box 26, the baffle 33 is turned downward to close the end of the sampling tube 21, at which time most of the plastic particles in the sampling tube 21 fall into the cyclone 25. Then the first valve body 22 is closed, the third valve body 24 is opened, the second fan 27 is started, the second fan 27 blows air into the sampling tube 21, plastic particles attached to the inner wall of the bottom end of the sampling tube 21 are blown down, and the blown plastic particles fall into the cyclone 25 and then fall into the collecting box 26. And then the third valve body 24 and the second valve body 23 are closed, and at the moment, the first valve body 22, the second valve body 23 and the third valve body 24 are all in a closed state, so that the sampling process is completed. The sample in the collection box 26 is then tested to determine if the plastic granules produced are acceptable.
After the conveying pipe 13 conveys the plastic particles for a period of time, when the plastic particles need to be sampled again, the wind shielding block 4 rotates upwards into the conveying pipe 13. The baffle 33 is rotated upward to a vertical state, at which time the filter plate 9 is in an inclined state. The filter plate 9 is separated from the baffle 33 during the upward rotation, and then the second torsion spring 16 makes the filter plate 9 abut against the limiting plate 10, so that the filter plate 9 can vibrate to shake down the plastic particles attached or blocked on the filter plate 9. Then the second fan 27 is started, the first valve body 22 and the third valve body 24 are started, the second fan 27 blows air into the sampling tube 21, the air blown into the sampling tube 21 by the second fan 27 can blow off plastic particles attached to the inner wall of the top end of the sampling tube 21, the blown plastic particles and the plastic particles vibrated from the filter plate 9 are sent into the conveying pipe 13, and the air flow flowing out of the sampling tube 21 is converged with the original air flow in the conveying pipe 13 and then is continuously conveyed along the conveying pipe 13.
Since the opening 3321 of the guide housing 332 at the side of the baffle 33 is aligned with the end of the air inlet pipe 751 at this time, a part of the air blown by the second fan 27 can flow into the guide housing 332, the air inlet pipe 751, the air inlet 81 and the accommodating part 82 in sequence, so that the connecting plate 72 rotates, the connecting plate 72 pushes the knocking block 73 to rotate to a side far away from the connecting post 6, and when the connecting plate 72 is separated from the contact with the knocking block 73, the first torsion spring 74 enables the knocking block 73 to rotate rapidly reversely to a state of abutting against the connecting post 6, so that the reset knocking block 73 can knock the connecting post 6, so that the connecting post 6 and the inner wall of the sampling tube 21 vibrate, and plastic particles adhered to the inner wall of the sampling tube 21 vibrate, so that the inner wall of the sampling tube 21 is further cleaned. Therefore, the mixing of plastic particles in the previous sampling and plastic particles in the subsequent sampling can be avoided, and the accuracy of sampling is prevented from being influenced.
After the inner wall of the sampling tube 21 is cleaned, the wind shielding block 4 rotates downwards to the lower part of the avoidance hole 131, the third valve body 24 is closed, the second valve body 23 is opened, and plastic particles in the conveying tube 13 enter the cyclone separator 25 through the sampling tube 21 to be sampled again.
