DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1: This embodiment is used to solve the problem that traditional hair duct molding is performed by hand lay-up on the molding mold, which lacks systematic collection and detection of impurities and defects on the overall surface of the mold, resulting in serious surface roughness of the hair duct after resin brushing due to the influence of the mold, aggravating the intensity and efficiency of subsequent surface treatment.

[0039] See also Figure 1 - Figure 8 As shown, this embodiment is a wind tube infusion molding device with a fiber layer pre-laying mechanism, including a blocking ring frame 1, a control panel 2 is fixedly installed on the top of one side of the blocking ring frame 1, a strip lifting frame 4 is arranged at the bottom of one end of the blocking ring frame 1, the top of the strip lifting frame 4 is rotatably connected with multiple groups of outer cylinder mold pieces 7, the inner cylinder mold piece 701 is sleeved inside the outer cylinder mold piece 7, the inner cylinder mold piece 701 is sleeved inside the center rod 703 fixedly connected to the blocking ring frame 1, a blocking mechanism 5 is slidably installed at the bottom of one end of the strip lifting frame 4, and the blocking mechanism 5 comprises a sliding frame 505, a ring plate 501 close to the center rod 703 is arranged on the top of the sliding frame 505, a gantry frame 6 connected to the blocking ring frame 1 is arranged above the sliding frame 505; a guide frame 602 extending to the top of the outer cylinder mold piece 7 is slidably installed inside the gantry frame 6, a fiber laying frame 3 is slidably connected to the middle of the guide frame 602, an adjusting frame 301 is sleeved on the top of the fiber laying frame 3, a plurality of groups of fiber spraying holes 304 are arranged on one end surface of the fiber laying frame 3, and a plurality of groups of brush rings 307 are sleeved on the other end surface of the fiber laying frame 3;

[0040] The control panel 2 is internally provided with a processor, a data acquisition module, a self-checking feedback module, a repeated comparison module and a signal execution module;

[0041] The data acquisition module collects the impurity ratio Qi and the mold wall defect value Wi of the annular molding mold cavity within a two-hour time threshold, and sends them to the self-checking feedback module through the processor, where i is a positive integer greater than zero;

[0042] It should be noted that: the impurity content ratio Qi is expressed as the maximum and minimum values ​​of the residual material area ratio on the inner wall of the annular molding cavity obtained within the time threshold of two hours, and the value of the impurity content ratio Qi reflects the amount of residual material in the annular molding cavity. The larger the value, the more it affects the duct molding quality and the fiber layer pre-laying effect. The mold wall defect value Wi is expressed as the amount of depressions or holes on the inner wall of the annular molding cavity obtained within the time threshold of two hours, and the value of the mold wall defect value Wi reflects the integrity of the inner wall of the annular molding cavity. The larger the value, the more the annular molding cavity needs maintenance. In addition, the slag content ratio Qi is collected by a scanning sensor installed on the fiber laying frame, and the mold wall defect value Wi is collected by an infrared sensor installed on the fiber laying frame.

[0043] After receiving the impurity ratio Qi and the mold wall defect value Wi, the self-checking feedback module immediately analyzes the mold loss efficiency of the device. The specific analysis process is as follows:

[0044] The impurity ratio Qi and mold wall defect value Wi of the annular molding mold cavity within the two-hour time threshold are obtained, and the formula The screening coefficient Soi is obtained, where a and b are the proportional coefficients of the impurity ratio Qi and the mold wall defect value Wi, respectively, a>b>0, and Soi is expressed as the mold loss coefficient, that is, the preset mold loss coefficient Yo stored and entered in the processor is retrieved for comparison and analysis with the mold loss coefficient Foi:

[0045] If the mold loss coefficient Foi ≥ the preset mold loss coefficient Yo, it is determined that there is an abnormality in the annular molding cavity, and a processing signal is generated and sent to the signal execution module through the processor. After receiving the processing signal, the signal execution module immediately controls the servo motor 305 to work, and the servo motor 305 drives the driving gear ring 306 to rotate through the coupling, and the driving gear ring 306 is engaged with the rotating ring 308. The rotating ring 308 drives the brush ring 307 to rotate, and the brush ring 307 rotates along the outer side of the fiber laying frame 3. Under the action of inertia, the brush ring 307 drags the telescopic traction rope 309 to deform and extend until the multiple groups of brush rings 30 7 respectively contacts with the inner wall of the outer cylinder mold piece 7 and the outer wall of the inner cylinder mold piece 701, and cleans the residual materials on their surfaces. At the same time, multiple groups of air jets are connected to the air pump 507 through pipelines. The air pump 507 provides a clean airflow for it. The clean airflow is sprayed along the air jets to brush the fallen material particles, causing them to roll along the bottom of the annular forming cavity. At the same time, the baffle of the slag outlet 101 is opened. When the fiber laying frame 3 reciprocates along the annular forming module, the fallen material particles are discharged along the slag outlet 101 and the dust suction port 503 under the influence of the clean airflow, the brush ring 307 and the internal pressure of the annular forming cavity.

[0046] If the loss factor Foi is less than the preset loss factor Yo, no signal is generated;

[0047] When the processor sends the processing signal to the signal execution module, the processor synchronously obtains the mold wall defect value Wi that generates the processing signal, and sends the obtained mold wall defect value Wi to the repeated comparison module. After receiving the mold wall defect value Wi, the repeated comparison module immediately retrieves the preset mold wall defect range P stored and entered from the processor for comparison and analysis with the mold wall defect value Wi;

[0048] If the mold wall defect value Wi ≥ the preset mold wall defect range P, the annular molding mold cavity is determined to be severely damaged, and a maintenance signal is generated. The processor converts the maintenance signal into text "sequence number Wi, mold wall is damaged" and sends it to the display screen in the main control room; if the mold wall defect value Wi < the preset mold wall defect range P, no signal is generated.
