[0001] The invention relates to the technical field of building waterproofing, moisture permeability, drainage and ventilation, and in particular to a rainproof curtain wall and a production method and application thereof. Background Art

[0002] When the temperature difference between indoor and outdoor is large, Figure 1 As shown, a large amount of moisture condensation will form on the outer surfaces of prefabricated buildings, shelters, wooden buildings and other buildings, affecting the life of the buildings.

[0003] In order to solve the above problems, Figure 2 As shown, in the prior art, a breathing paper (ie, waterproof and breathable cloth, housewrap) is often added to the outer surface of the building to cause moisture condensation to occur on the surface of the breathing paper.

[0004] However, since the surface of the breathing paper does not have a drainage structure to guide the flow of moisture condensation, the moisture condensation on the surface of the breathing paper cannot be removed in time due to capillary action, and it is difficult to ensure the dryness of the surface of the breathing paper and the back of the exterior wall. Therefore, mold is easily formed, reducing the service life of the building. Summary of the invention

The storage mechanism can temporarily store a part of the roll material so that the entire production line can maintain continuous operation; the second production method is that the dripping device drips the material liquid on the inner layer. After the material liquid dripped on the inner layer is cooled, it forms an elastic protrusion that is bonded and fixed to the surface of the inner layer, thereby achieving fixation between the elastic protrusion and the inner layer. The hot melt roller is used to heat the elastic protrusion to make the elastic protrusion have a certain viscosity. , and then the fixation between the elastic protrusion and the surface layer is realized, thereby completing the processing of the entire rainproof curtain wall; the third production method is based on actual use needs. When the inner layer is the first mesh structure layer and the surface layer is the second mesh structure layer, the inner layer and the surface layer are both fed to the hot pressing roller, and the elastic protrusion falls into the hot pressing roller. After the hot pressing roller heats the two ends of the elastic protrusion, the elastic protrusion is pressed and fixed between the inner layer and the surface layer, thereby completing the processing of the rainproof curtain wall; when the inner layer is a waterproof and breathable layer and the surface layer is the second mesh structure layer, the surface layer is fed to the hot pressing roller, and the elastic protrusion provided by the feed bin is The protrusion falls into the hot pressing roller, and after the hot pressing roller heats one end of the elastic protrusion, the elastic protrusion is pressed and fixed on the surface layer, and the surface layer with the elastic protrusion fixed continues to be fed to the pressing roller. During the feeding process, the other end of the elastic protrusion is heated by the heating tube, so that the elastic protrusion has a certain viscosity, so that when the surface layer is fed to the pressing roller, the inner layer fed to the pressing roller can be pressed and fixed with the other end of the elastic protrusion by the pressing roller, thereby completing the processing of the rainproof curtain wall; all three production methods can be used to manufacture rainproof curtain walls, and the cost is relatively low. The second and third production methods have simpler processes;

The number of the first guide tube 632, the second guide tube 634, the manipulator 633 and the cutting knife 635 corresponds to the number of the material columns. The first guide tube 632, the second guide tube 634, the manipulator 633 and the cutting knife 635 are arranged side by side along the frame 631 horizontally. The material column led out from the feeding bin 61 passes through the first guide tube 632 and the second guide tube 634 in sequence and is located above the feeding crawler 62. The feeding crawler 62 is provided with a feeding trough 621, and the feeding trough 621 can be used for the material column to fall into. When the material column is completely inserted into the feeding trough 621 driven by the manipulator 633, the cutting knife 635 is controlled by the driving motor to work and cut off the material column. The material column segment falling into the feeding trough 621 is the elastic protrusion 2, thereby realizing the cutting and dropping of an elastic protrusion 2. A counterpoint vacuum roller (not shown in the figure) is arranged under the feeding track 62, and the counterpoint vacuum roller is connected to a vacuum pump 64. The number of vacuum pumps 64 is set to be multiple, and one of them is shown in the figure. Vacuuming is achieved by the vacuum pump 64 to achieve stable dropping of the elastic protrusion 2.

The feeding track 62 carrying the elastic protrusion 2 continues to transmit, and the upper end of the elastic protrusion 2 is heated by the heating mechanism 9 to melt. The heating mechanism 9 can adopt a radiation heating structure. The first unwinder 4 is a double-station unwinder, so that when one roll of raw material is used up, the head end of the other roll of raw material is bonded to the tail end of the exhausted raw material, and can work uninterruptedly. The inner layer 1 provided by the first unwinder 4 enters from the first bonding mechanism 7, and the hot-melt surface of the elastic protrusion 2 is bonded to the surface of the inner layer 1 by pressing, so that single-sided processing is realized. Secondly, it is transmitted to the second bonding mechanism 8, in which there is a counterpoint heat-conducting roller, and the surface of the counterpoint heat-conducting roller generates heat, so that the surface of the elastic protrusion 2 is thermally melted without damaging the surface layer 3. The surface layer 3 comes from the second unwinding machine 5, and the second unwinding machine 5 adopts a single-station unwinding structure.

[0106] The initially completed product is the rainproof curtain wall, which is transmitted to the storage mechanism 10. The storage mechanism 10 includes a cloth storage rack 101, on which a cloth storage wheel 102 is provided. The rainproof curtain wall is wound through each cloth storage wheel 102, wherein two cloth storage wheels 102 are slidably connected with the vertical rods of the cloth storage rack 101, so that the rainproof curtain wall is tightened. When the winding mechanism 11 suspends winding, each mechanism of the front station continues to operate, and at this time the storage mechanism 10 can store a part of the rainproof curtain wall to achieve caching. The winding mechanism 11 includes a winding frame 111 and a flip frame 112 arranged on the winding frame 111, a flip motor 113 is arranged on the winding frame 111, and the flip motor 113 is used to drive the flip frame 112 to flip, and a winding motor 114 and a winding wheel 115 are connected to the flip frame 112, and the winding motor 114 drives the winding wheel 115 to rotate, and the winding motor 114 adopts a constant tension winding method to wind, and a clamping cylinder 116 is arranged outside the winding wheel 115, and a clamping wheel 117 is arranged on the piston rod of the clamping cylinder 116, and the winding wheel 115 presses the rainproof curtain wall through the clamping wheel 117 to realize the winding of the rainproof curtain wall; when the winding work of one of the winding wheels 115 is saturated, the flip motor 113 works, and the rainproof curtain wall is cut off at a fixed length, which can be cut manually or by an automatic cutter, and the other winding wheel 115 is replaced for winding, reciprocating turnover, and uninterrupted work.
