Technical Field

[0001] The utility model relates to the technical field of waterproof membrane forming, in particular to a PVDF waterproof membrane forming device. Background Art

[0002] PVDF waterproofing membrane is a polymer composite material with excellent properties. During its production, PVDF is first dissolved in an organic solvent and an appropriate amount of surfactant is added to form a mixed solution.

People skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation methods disclosed below.

[0027] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0029] The utility model provides a film-forming device for a PVDF waterproof membrane. By cooperating with a waterproof membrane forming component and a liquid collecting component, the unformed raw material solution brought out by taking out the waterproof membrane during use can be recycled, thereby avoiding waste of raw materials and improving the forming output of the waterproof membrane.

[0030] Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The figure shows the overall structure of a film forming device of a PVDF waterproof membrane of the utility model. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , the main structure of this embodiment includes: a waterproof membrane forming component and a liquid collecting component;

[0031] The waterproof membrane forming assembly is used for producing PVDF waterproof membrane. Specifically, the waterproof membrane forming assembly includes a film forming frame 11, a waterproof membrane forming groove 12 provided in the middle of the film forming frame 11, and an annular notch 13 provided at the edge of the film forming frame 11.

[0032] During specific use, the user pours the PVDF solution into the waterproof film forming tank 12, and then places the film forming frame 11 in the inorganic solvent. In this way, the PVDF waterproof film is formed under the interaction of the organic solvent and the inorganic solvent, and then the user can take out the PVDF waterproof film.

[0033] The liquid collection assembly is used to recover the raw liquid. Specifically, the liquid collection assembly includes a first slope plate 21 disposed in the annular notch 13, a liquid outlet pipe 22 connected to the annular notch 13, a liquid collection frame 23 attached to the outer wall of the film forming frame 11, a second slope plate 24 disposed on the inner bottom surface of the liquid collection frame 23, and a liquid outlet hose 25 connected to the liquid collection frame 23;

[0034] During specific use, the user takes out the PVDF waterproof membrane. During the removal process, a portion of the unreacted PVDF solution will be brought out by the PVDF waterproof membrane. The PVDF solution brought out at this time will drip into the annular notch 13. At this time, due to the presence of the first ramp plate 21, the PVDF solution will flow and gather, and finally be discharged into the liquid collecting frame 23 through the liquid outlet pipe 22. At this time, due to the presence of the second ramp plate 24, the solution in the liquid collecting frame 23 is gathered at the position of the liquid outlet hose 25, and finally discharged and collected through the liquid outlet hose 25.

[0035] Furthermore, the surroundings of the film-forming frame 11 are sealed and isolated by the provided enclosure assembly to ensure that the PVDF solution brought out by the waterproof film is collected and stored by the annular notch 13 to avoid overflow.

[0036] Specifically, it also includes an enclosure assembly, which includes a threaded hole 31 opened on the top surface of the film forming frame 11, an annular bottom plate 32 set above the film forming frame 11, and a circular hole 34 opened on the surface of the annular bottom plate 32. The enclosure assembly also includes an annular baffle 33 fixed on the top surface of the annular bottom plate 32;

[0037] During specific use, a threaded rod is connected to the threaded hole 31, and the threaded rod locks the annular bottom plate 32. At this time, the annular baffle 33 can be installed to block the PVDF solution, ensuring that the PVDF solution is gathered through the annular notch 13 to improve the collection efficiency.

[0038] Furthermore, by providing a diversion component, the PVDF solution is prevented from staying on the film forming frame 11 and the PVDF solution is diverted into the annular notch 13 as much as possible to improve the recovery efficiency.

[0039] Specifically, the invention also includes a flow guide component, which includes a first arc surface 41 and a second arc surface 42 provided at the edge of the film forming frame 11;

[0040] In specific use, the first curved surface 41 and the second curved surface 42 are designed to be curved. In this way, if PVDF solution stays on the film forming frame 11, the PVDF solution will be directly diverted to avoid staying, thereby further improving the recovery efficiency.

[0041] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
