The operation principle of the present embodiment is specifically as follows:
The first step: placing the material in the detection conveyor belt 28, at this time, the motor 12 is started to drive the hollow conveyor belt 16 to run, and the detection conveyor belt 28 starts to rotate at the same speed as the hollow conveyor belt 16 along with the running of the hollow conveyor belt 16, because the power of the detection conveyor belt 28 is derived from the power rod 22, and the power of the power rod 22 is derived from the power wheel 23 (the power wheel 23 is in contact with the hollow conveyor belt 16, the power wheel 23 which rotates along with the running of the hollow conveyor belt 16 transmits the power to the power rod 22 through the belt 221), when the material contacts the detection conveyor belt 28, due to the storage weight of the material itself, the detection conveyor belt 28 is depressed to a corresponding extent, and along with the depression of the detection conveyor belt 28, the weight of the material is transmitted to the force receiving plate 26, when the weight of the material is transferred to the force plate 26, the force plate 26 starts to descend, and as the force plate 26 descends, the pressure detector 27 is pressed, and in order to make the weight of the material more concentrated on the pressure detector 27 through the force plate 26, the pressure conductive block 261 and the conductive rod 262 are disposed in the force plate 26 (since the pressure conductive block 261 has a gradually decreasing length in the force plate 26, the pressure conductive block 261 can guide and concentrate the force in the force plate 26 as much as possible at the end point of the conductive rod 262 by changing the transfer path and the force distribution of the pressure acting on the force plate 26, and the pressure detector 27 can obtain the current weight of the material by detecting the descending force in the conductive rod 262, the pressure detector 27 will then transmit the weight information of the current material to the air booster 13 (in order to avoid special situations, the pressure detector 27 will take the first three materials after the start of the device as standard, if the weights of the first three materials are consistent, then signal is transmitted to the air booster 13, if the weights of the first three materials are inconsistent, the device will stop working, and give an early warning, so that the air booster 13 can provide a corresponding air flow according to the weight of the material by manually checking whether the materials delivered by the pushing device are of the same type).
Wherein, as the force plate 26 descends, the spring 25 starts to compress (because the force required by the compression of the spring 25 is fixed, the force consumed by the compression of the spring 25 by the force plate 26 is additionally supplemented when the pressure detector 27 detects the force generated by the downward pressing of the force plate 26), and as the material is separated from the detection conveyor belt 28, the force acting on the force plate 26 also disappears, and at this time, the spring 25 is compressed, so that the force plate 26 returns to the initial state, and the weight of the material is detected by the force plate 26 for the next time.
And a second step of: the materials detected by the weighing mechanism 2 are conveyed into the inclined groove 32 of the inclined block 31 through the detection conveyor belt 28, and the inclined block 31 has a certain inclined angle, so that the materials slide in the inclined groove 32, and the inclined groove 32 forms a high friction area and a low friction area from high to low according to the difference of the densities of the friction points 34 in the inclined groove 32, so that the friction points 34 in the high friction area are more in number, the friction force is also larger, the sliding speed of the materials in the high friction area is slow, the sliding speed of the materials in the low friction area is less in number, the sliding speed of the materials in the high friction area is fast, the sliding speed difference of the materials in the inclined groove 32 is formed, and the time for realizing that the materials slide out of the inclined groove 32 into the hollowed conveyor belt 16 is inconsistent (the time here means that the materials slide down in the high friction area and the low friction area of the inclined groove 32), so that the space is formed between the materials, and the collision and damage occurring in the process of conveying and packaging can be reduced.
The air booster 13 is started after receiving the information corresponding to the pressure detector 27, so as to generate a corresponding air flow, and the air flow is respectively conveyed to the speed reducing mechanism 3 and the specification detecting mechanism 4 through the first air pipe 141 and the second air pipe 142, the air conveyed by the second air pipe 142 can be divided into a plurality of parts through the flow divider 36, so that the air holes of each polygon of the honeycomb block 35 can uniformly receive the air conveyed by the second air pipe 142, and the air conveyed by the second air pipe 142 to each polygon air hole of the honeycomb block 35 can enable the honeycomb block 35 to vibrate (according to the fluid mechanics principle, when the air flow passes through the honeycomb block 35 with an open structure, the air flow in the structure forms a larger pressure difference, so as to cause vibration of the honeycomb block 35), and the air conveyed by the second air pipe 142 can be divided into a plurality of parts through the flow divider 36, so that the air conveyed by the second air pipe 142 can uniformly receive the air conveyed by the second air pipe 142, and the air in each polygon air hole of the honeycomb block 35 can vibrate (according to the fluid mechanics principle, when the air flow passes through the honeycomb block 35 with the open structure, the honeycomb block 35), the air flow can not generate the vibration, so that the vibration can not continuously overcome the vibration effect due to the sliding friction of the material, and the vibration can not be continuously provided.
Wherein, through setting up single section blend stop 33 and two section blend stops 37 respectively in high friction area and low friction area, can carry out the guide effect to the gliding material in the sloping piece 31, thereby make the material that gets into in the fretwork conveyer belt 16, can be located the central point of fretwork conveyer belt 16, and neatly arrange, when the material neatly arrange and be located the fretwork conveyer belt 16 center, pushing equipment can more evenly propelling movement and carry the material, this can reduce the card that leads to because of the material is inhomogeneous or unstable in the transportation, stagnate or other problems, improve conveying efficiency, simultaneously, the material of neatly arranging can receive less extrusion, roll or other forms damage when being pushed generally, because the clearance between them is more even, the transportation process is more steady.
And a third step of: the material processed by the speed reducing mechanism 3 can enter the hollow conveyor belt 16 for further transmission, in the transmission process, the specification detecting mechanism 4 can detect the specification of the material, when the material passes through the hollow conveyor belt 16 and the specification detecting mechanism 4, the air booster 13 can further process the material through the first air pipe 141, the air flow conveyed by the air booster is respectively conveyed through the split pipes 44 in the two main pipes 42, the air flow conveyed by the first air pipe 141 is conveyed through the air inlet pipe 45 by the main pipes 42, the air inlet pipe 45 further carries out split operation on the air flow through the split ring 452, so that the air flow is discharged through the air discharging piece 47, the split ring 452 rotates along with the power generated when the air discharging piece 47 discharges the air, so that the air discharging piece 47 discharges the air flow in the air discharging box 43 to form a spiral air flow state, and simultaneously the rotating air flow can be further processed by the air flow ring 431, so that the rotating speed of the air booster is increased (because the air flow ring 431 is provided with a plurality of annular grooves which are vertically distributed, according to the law of angular conservation, when the fluid passes through the annular grooves, the air flow is enhanced because of guiding, the air flow is guided by the air flow through the air inlet pipe 45, the air flow is discharged through the air inlet pipe 47, the air flow is enabled to take on the spiral state, and the spiral flow state is further takes on the spiral state after the spiral state, the air flow is enabled to take on the spiral state, the material is further takes the spiral state, the material is further in the spiral state, the material is further takes the flow is guided by the spiral state, and the material is further in the spiral state, and the flow is further, the material is processed, and the flow is further, and the material is further in the flow is processed, and the spiral state, and the flow is and the is further, and the flow is further, and the is processed, and the is further, and the is and the by the flow.
The airflow measuring device 5 is used for receiving the spiral airflow generated by the specification detecting mechanism 4, and since the spiral airflow acts on the material (the spiral airflow can uniformly cover the surface of the material in a relatively wide area), the spiral airflow can effectively cover and contact the surface of the material no matter how large the surface of the material is, so that the accuracy and reliability of detection of the airflow measuring device 5 are ensured, the spiral airflow blocked by the material cannot be received by the airflow measuring device 5, and the specification of the material is judged according to the area of the spiral airflow blocked by the material, so that whether abnormal material exists is judged.
The criteria for judging whether the material is abnormal are as follows:
when a large amount of materials pass through the specification detection mechanism 4, the blocking area of the materials caused by the spiral gas transmitted by the specification detection mechanism 4 is the same, for example: the first 5 materials passing through the specification detection mechanism 4 have the same blocking area, and the 6 th material has different blocking areas, which indicates that the 6 th material specification is abnormal.
Therefore, the specification of the material is judged according to the area of the material blocking spiral airflow, whether abnormal materials exist or not is judged, and only the materials meeting the specification can be ensured to enter the packaging process by detecting the abnormal materials, so that the quality of a final product is improved.
