Further, for a failed coiled material felt product which has been subjected to spot inspection and has not passed the body inspection in one batch, the body pass authority is not uniformly given, but needs to be recovered.
Preferably, for the coiled material felt product to be modified, the first detecting unit 100 can also separately detect the diversion net for coiled material modification to determine whether the internal structure of the diversion net meets the customization standard, thereby determining the modification effect of the coiled material, and the coiled material felt product with good modification effect can be given qualified authority to the body, wherein the diversion net and the main material can be coiled into the coiled material product through the winding mechanism, so as to guide the continuous and unimpeded flow of the modification liquid between the layers of the main material by means of a plurality of diversion channels 600 arranged on the diversion net.
Preferably, the diversion channel 600 of the diversion net satisfying the custom standard category may be configured as follows:
the diversion channel 600 of the diversion net at least comprises a plurality of first flow channels 601, and a plurality of second flow channels 602 symmetrically distributed based on the first flow channels 601 are arranged around each first flow channel 601; the second flow path 602 is extended from one end of the first flow path 601 to the opposite end of the first flow path 601 in communication with each other by a predetermined distance, and the diameter of the second flow path 602 is preferably larger than that of the first flow path 601. The arrangement of the plurality of second flow channels 602 can enhance the mobility of the modifying liquid in the diversion channel 600, which is beneficial to the outflow of other solvents or solutes displaced by modification, and avoids the degradation of the modifying effect caused by retention of the modifying liquid and other solvents. The second flow channels 602 symmetrically distributed around the first flow channel 601 are communicated through a plurality of third flow channels 603, the diameter of the third flow channels 603 is smaller than that of the second flow channels 602 and/or the diameter of the first flow channels 601, and the plurality of first flow channels 601 are arranged at intervals, so that the first flow channels 601, the second flow channels 602 around the first flow channels 601 and the third flow channels 603 communicated with the second flow channels 602 can form diversion monomers, and adjacent diversion monomers are connected through fourth flow channels 604. The third flow channel 603 can further control or improve the flow rate and pressure variation of the modifying liquid at each input or output node of the diversion channel 600, and utilize the pressure difference to promote the modifying liquid to flow continuously and smoothly inside the diversion channel 600, so as to guide the modifying liquid to continuously flow through and diffuse to the main material between the diversion net layers, thereby being beneficial to the efficient completion of the modification of the main material.
Further, a plurality of diversion monomers connected in series through the fourth runner 604 may form a diversion chain, and the diversion monomers between adjacent diversion chains and the fourth runner 604 are distributed in a staggered manner, so that the protrusions and the depressions formed by the second runner 602 are staggered with each other, thereby increasing the coverage area of the diversion channel 600 on the diversion net as much as possible. In this configuration mode, the diversion channel 600 on the diversion net is configured into a plurality of diversion chains which are not interfered with each other, and the contact area and the contact time between the modifying liquid in the diversion channel 600 and the main material are increased as much as possible, thereby improving the modifying effect.
Preferably, the sum of the diameters of the first flow channel 601 and the plurality of second flow channels 602 is not smaller than the diameter of the fourth flow channel 604; alternatively, the diameter of any of the second flow channel 602 or the first flow channel 601 is larger than the diameter of the fourth flow channel 604. In this arrangement, the velocity of the modifying liquid flowing through the second flow path 602 is greater than the velocity of the modifying liquid flowing through the fourth flow path 604. When the modifying liquid passes through the diversion channel 600 in the diversion net, the first runner 601 of the diversion channel 600 is divided into a plurality of flow paths with reduced caliber by the second runner 602, thereby enhancing the mobility of the modifying liquid in the diversion channel 600 so as to increase the flow velocity of the modifying liquid.
Preferably, in one flow directing unit, the plurality of second flow channels 602 around the first flow channel 601 form a substantially central bulged ellipsoidal ring flow channel. Further, the sides of the second flow channel 602 on either side of the ellipsoidal flow channel are generally streamlined. The radius of curvature of the front end of the second runner 602 on the ellipsoidal ring runner is preferably greater than the radius of curvature of the rear end thereof. In this arrangement, the modifying liquid flowing through the ellipsoidal ring passage from the fourth passage 604 can form a vortex to prevent the modifying liquid from stagnating in the guide passage 600, thereby helping the modifying liquid to flow out in the guide net as much as possible.
Preferably, the second flow channels 602 on the ellipsoidal ring flow channels are communicated through the third flow channels 603, as shown in fig. 2, which is two preferred embodiments of the diversion monomer, and the first detection unit 100 can randomly select points on the diversion net to detect the internal structure of the diversion monomer. In a preferred embodiment, a plurality of third channels 603 form a substantially Y-shaped branching path between adjacent second channels 602, each third channel 603 is connected to the second channels 602 of each ellipsoidal ring channel by a Y-shaped structure, and between the same ellipsoidal ring channels, the third channels 603 communicate the ends of the Y-shaped structure, i.e. the third channels 603 have a specific structure that two branches are respectively connected to the second channels 602 at two ends, and the two branches at two ends are respectively communicated by a transverse channel. In another preferred embodiment, the plurality of third flow channels 603 form a substantially transverse "H" shape between adjacent second flow channels 602, i.e. two third flow channels 603 are respectively communicated between the same ellipsoidal flow channel, and a vertical third flow channel 603 (not shown in the figure and blocked by the first flow channel 601) is provided at a middle position on the two transversely communicated third flow channels 603 for communicating the two transverse third flow channels 603.
With the above arrangement, after the modifying liquid is injected, the modifying liquid enters each second flow channel 602 through the fourth flow channel 604, flows through each second flow channel 602 at a flow rate higher than the flow rate of the modifying liquid in the fourth flow channel 604, and flows through the second flow channel 602 to the fourth flow channel 604 at the rear end and the next ellipsoidal flow channel having two second flow channels 602 in a split-flow and combined-flow manner. Further, while the modifying liquid flows in each second flow channel 602, the modifying liquid in the second flow channels 602 enters into the plurality of third flow channels 603 due to the pressure change caused by the difference of the flow rates, and flows back or merges into the corresponding second flow channels 602 again through the third flow channels 603. In other words, the modified liquid in the second flow path 602 completes the secondary diversion and merging through the third flow path 603 having a smaller diameter.
