Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.
Referring to fig. 1-4, a method for rapidly laying auxiliary materials according to the present invention mainly comprises the following steps:
1. firstly, a PVC triangular runner and a runner backing plate are manufactured into an integrally formed structure 2 by using a forming process (as shown in figures 3 and 4), wherein a glue guide opening can be fixedly placed above the triangular runner (as shown in figure 4) at a position with a glue injection opening to form another integrally formed structure 1; in this embodiment, the PVC triangular flow channel and the flow channel backing plate may be bonded or combined by a snap-and-mortise structure.
In this step, in order to facilitate mass production and control of cost, the conventional PVC triangular runner and the runner plate are usually processed separately, and in addition, in the blade production process, the PVC triangular runner is a necessary material, and the runner plate is only an auxiliary material for ensuring product quality, and is not necessarily present under all PVC runners. Therefore, in the embodiment of the invention, a binding and bonding form similar to an adhesive tape can be used to combine the PVC runner and the runner liner plate into a whole, and a clamping groove can be designed on the PVC runner or the runner liner plate, and the clamping and riveting combination can be performed in a pulling and pulling manner.
2. Thirdly, manufacturing the demoulding cloth, the porous membrane and the flow guide net into an integral sleeve material so that the integral sleeve material can be used as a whole;
the specific implementation method in this embodiment is gluing, or hot-press molding by utilizing the thermoplastic properties of the porous membrane and the flow guide net, so that the integrated sheathing can be used as a whole without affecting the paving effect.
3. Finally, fixing the integrated sleeve material with the PVC triangular flow channel and the flow channel base plate on the integrated sleeve material of the demoulding cloth, the porous membrane and the flow guide net by using nylon threads or fiber yarns;
4. manufacturing and processing according to the drawing of the skin auxiliary material of each model (as shown in figure 5);
in the step, the application stage of the integral auxiliary material is mainly adopted, the required integral auxiliary material profiles are different due to different types of blade products, the combination mechanisms of the integral auxiliary material profiles are all formed by combining the materials in the description, and the drawing of the skin auxiliary material is only used for size processing so as to facilitate on-site laying; the profile size of the auxiliary material is closely related to the quality of a blade production product, and mature equipment performs profile shape cutting according to a processing drawing at the present stage, so that in the embodiment, the step can be skipped or simplified, the profile size of the auxiliary material is not accurately corrected, but a part of the equipment cutting area 5 is reserved for using equipment for cutting in a subsequent procedure, so as to ensure that the profile size of the auxiliary material is accurate and consistent.
5. Laying the integrated cover material formed by processing various types
The step is the field application stage of the integrated auxiliary material method, namely the integrated auxiliary material formed in the steps can be applied to the production of the blade, the method for laying the auxiliary material layer by layer in the original stage can be changed into the method for directly laying the integrated auxiliary material once, and the main purpose of the invention is realized.
In conclusion, by firstly composing the integrated cover material, the operator can complete the laying of all the auxiliary materials of the skin only by one laying step, thereby reducing the number of times of the back-and-forth laying and improving the efficiency.
Although the present invention has been described in detail with reference to the above embodiments, it should be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention.
