Description

Technical Field

[0001] The invention relates to the technical field of geotextile production and manufacturing, and specifically provides a waterproof composite geotextile rolling device. Background Art

[0002] Waterproof composite geotextile is a high-performance composite material used in civil engineering, water conservancy engineering, environmental protection engineering, transportation infrastructure construction and other fields. It is generally composed of multiple layers of materials, but usually includes at least one layer of geotextile and one layer of waterproof membrane. Its design purpose is to combine the filtration, drainage, isolation and reinforcement functions of geotextile and the anti-seepage performance of waterproof membrane to provide a material that can protect soil and groundwater from pollution and enhance structural stability.

[0003] Geotextile and waterproof membrane can be tightly compounded with the help of adhesives, and the waterproof membrane itself will improve its fluidity and plasticity after heating, thereby producing a certain degree of viscosity. Therefore, in the actual composite processing process, the waterproof membrane is usually preheated, and then the waterproof membrane is rolled and compounded on the geotextile by a hot pressing roller to form a waterproof composite geotextile. In the actual production process, the composite strength is sometimes reduced due to various reasons, which in turn affects the actual waterproof performance of the waterproof composite geotextile. The main reasons include the following: 1) Before rolling compounding, although the waterproof membrane or geotextile is in a taut state in the conveying direction, it is not fully opened laterally, resulting in wrinkles after the two are compounded. There is a problem of adhesion failure at the wrinkles, which in turn causes the local composite strength of the waterproof composite geotextile to be low.

[0004] 2) During the transportation process after preheating, there is heat exchange between the waterproof membrane and the environment, which makes the surface temperature of the waterproof membrane drop. Especially when the ambient temperature is low, the heat loss on the surface of the waterproof membrane is accelerated, and heat conduction will also occur during the rolling contact with the geomembrane, which further reduces the surface temperature of the waterproof membrane. The waterproof membrane and geomembrane are instantly rolled and compounded by the hot pressing roller during transportation. When the surface temperature of the waterproof membrane is low and the hot pressing roller cannot provide effective temperature compensation instantly, the fluidity and plasticity of the waterproof membrane material will be reduced, and it cannot provide effective adhesion, which ultimately causes the composite strength of the waterproof composite geotextile to be reduced.

[0005] In summary, it is necessary to solve the above problems to ensure the composite strength of the waterproof composite geotextile and maintain its effective waterproof performance. Summary of the invention

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

The composite roller group 6 is an existing hot pressing and compounding forming structure, including a hot pressing roller 62 and a support roller 61 distributed up and down. Among them, the position of the support roller 61 on the frame 1 is fixed, while the hot pressing roller 62 can be vertically lifted relative to the support roller 61 to adjust the compounding gap and pressure.

[0036] As Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8As shown in the figure, a hot air device 2 is assembled on a frame 1. The hot air device 2 includes a support base 21 welded to the frame 1. At the top of the support base 21, there is a fixed support plate 211. Horizontally welded to the upper end of the fixed support plate 211 is a buffer air box 22 for introducing hot air. The buffer air box 22 is of a cubic box structure, and the hot air is dry pressurized air flow. The buffer air box 22 is connected through a pipeline to introduce pressurized hot air. The upper end surface of the buffer air box 22 is distributed with exhaust contact heads 23 in a rectangular array. The exhaust contact heads 23 are in conduction with the buffer air box 22, and the exhaust contact heads 23 are made of soft elastic material, specifically, it can be silicone material. The pressurized hot air will first be buffered and filled in the buffer air box 22, and then further evenly dispersed and discharged outward from each exhaust contact head 23.

The fabric guiding mechanism 3 includes a material supporting component 31 and a material pressing component 32 that are vertically slidably installed on the support base 21. The support base 21 is also equipped with a reverse driving component 33 that drives the material supporting component 31 and the material pressing component 32 to slide in opposite directions. A film material guiding mechanism 4 that rises and falls synchronously with it is fixedly installed on the material pressing component 32. The film material guiding mechanism 4 is located directly above the buffer air box 22.

[0038] As Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig. 9 shown in the figure, the material supporting component 31 includes two first roller frames 311. At the bottom end of the fixed support plate 211, two groups of first guide columns 212 corresponding to and cooperatively arranged with the two first roller frames 311 are vertically welded. The number of each group of first guide columns 212 is two. The first roller frame 311 includes a U-shaped plate 3111 vertically slidably installed on the two first guide columns 212. The fixed support plate 211 is located in the notch of the U-shaped plate 3111. Bearing plates 3112 are oppositely welded on the two side walls of the U-shaped plate 3111. A group of material supporting rollers 312 are horizontally rotatably installed between the two bearing plates 3112 on the same side of the two first roller frames 311. The buffer air box 22 is arranged in the middle of the two groups of material supporting rollers 312. The number of a single group of material supporting rollers 312 is two.

[0039] As Figure 2 , Figure 5 and Figure 7As shown, two groups of side-tensioned conveying components 5 are fixedly mounted on the supporting assembly 31, and the two groups of side-tensioned conveying components 5 are sequentially distributed in the conveying direction of the cloth 71, and the two groups of side-tensioned conveying components 5 are arranged one by one with the two groups of supporting rollers 312; each group includes two side-tensioned conveying components 5, and the two side-tensioned conveying components 5 are symmetrically arranged in a direction perpendicular to the conveying direction of the cloth 71, and the cloth 71 is synchronously tensioned laterally when being conveyed by the two side-tensioned conveying components 5. The two side-tensioned conveying components in each group are mounted one by one on the two bearing plates 3112 on the same side of the two No. 1 roller frames 311, and a corresponding group of supporting rollers 312 is located between the two side-tensioned conveying components.

[0040] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the side-stretching conveying component 5 includes a connecting plate 51 welded on the bearing plate 3112, a fixed shaft plate 511 is welded on the connecting plate 51, a pressing cylinder 52 is vertically fixed on the connecting plate 51 by bolts, a lifting shaft plate 521 is welded on the output end of the pressing cylinder 52, a group of inclined rollers 53 are respectively installed horizontally and rotatably on the fixed shaft plate 511 and the lifting shaft plate 521, and the two groups of inclined rollers 53 are vertically correspondingly arranged. In this embodiment, the number of each group of inclined rollers 53 is three, and the inclined rollers 53 are existing electric rollers that can be driven independently. The inclined rollers 53 are arranged obliquely relative to the conveying direction of the cloth 71, and the three inclined rollers 53 are evenly distributed in the horizontal straight line direction perpendicular to the axial direction thereof; the two inclined rollers 53 in the two symmetrically arranged side-stretching conveying components 5 that are in relative positions are arranged in an inverted eight-shaped manner in the direction facing the conveying direction of the cloth 71 (such as Figure 3 From left to right perspective); the conveying surface of the lower set of inclined rollers 53 is flush with the conveying surface of the set of support rollers 312. The cloth 71 passes through the two sets of inclined rollers 53. The upper set of inclined rollers 53 can be adjusted by adjusting the pressure cylinder 52 to adjust the passing gap, thereby adjusting the pressure on the cloth 71. Figure 4 As shown in FIG. 1 , during operation, the upper inclined roller 53 rotates clockwise, and the lower inclined roller 53 rotates counterclockwise. Due to the inclined arrangement of the inclined roller 53, Figure 3 Specifically, the two side-tensioning conveying components 5 located at the upper position will generate a horizontal leftward conveying traction force and simultaneously generate a vertical upward lateral tension, while the two side-tensioning conveying components 5 located at the lower position will generate a horizontal leftward conveying traction force and simultaneously generate a vertical downward lateral tension. The common horizontal leftward conveying traction force can pull the cloth 71 for conveying, and the upper and lower opposite lateral tensions can make the cloth 71 open laterally and can offset each other without causing the conveying position of the cloth 71 to shift.

[0041] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 and Fig.10 As shown, the pressing assembly 32 includes two No. 2 roller frames 321 vertically slidably mounted on the support seat 21, and two groups of No. 2 guide pillars 213 corresponding to the two No. 2 roller frames 321 are digitally welded at the bottom end of the fixed support plate 211, and the number of each group of No. 2 guide pillars 213 is two, and the No. 2 roller frame 321 is an L-shaped plate structure. The horizontal plate of the No. 2 roller frame 321 slides vertically on the two No. 2 guide pillars 213, and two pressing rollers 322 are horizontally rotatably installed between the vertical plates of the two No. 2 roller frames 321; the two pressing rollers 322 are centrally distributed between the two groups of supporting rollers 312.

[0042] like Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig.10 and Fig.11 As shown, the film material guiding mechanism 4 is fixed between the top ends of the two No. 2 roller frames 321 and is located between the two pressure rollers 322. The film material guiding mechanism 4 includes two No. 3 roller frames 41 fixed to the top ends of the two No. 2 roller frames 321 by bolts one by one. Three conveying guide rollers 42 are installed horizontally and rotatably on the two No. 3 roller frames 41. The three conveying guide rollers 42 are arranged in an isosceles triangle. The top end of the No. 3 roller frame 41 is in a herringbone shape. Two plug holes 411 are arranged on the No. 3 roller frame 41. A cover 43 is plugged and installed between the two No. 3 roller frames 41. The cover 43 is in a herringbone plate structure, and a plug rod 431 corresponding to each plug hole 411 is welded on the cover plate.

[0043] like Figure 4 , Figure 6 , Figure 8 and Fig. 9As shown, the reverse drive assembly 33 includes a lifting cylinder 331 vertically fixed to the bottom end of the fixed support plate 211, and the output end of the lifting cylinder 331 is horizontally equipped with a double-headed telescopic rod 332, and the double-headed telescopic rod 332 includes a telescopic guide tube 3321 fixed to the output end of the lifting cylinder 331 and two telescopic rods 3322 slidably fitted at both ends of the telescopic guide tube 3321, and the ends of the two telescopic rods 3322 are hinged with connecting rods 333, and the two connecting rods 333 are symmetrically arranged. Each No. 2 roller frame 321 is arranged in a one-to-one correspondence with two connecting rods 333; there are two waist-shaped holes 3331 distributed on the connecting rod 333, and a hinge seat 334 is welded to the bottom end of the fixed support plate 211 and the two connecting rods 333 respectively, and the part of the connecting rod 333 located between the two waist-shaped holes 3331 is hinged on the corresponding hinge seat 334, and one of the waist-shaped holes 3331 is movably hinged to the bottom of the No. 1 roller frame 311, and the other waist-shaped hole 3331 is movably hinged to the bottom of the No. 2 roller frame 321.

[0044] The relative position height of the material supporting assembly 31 and the material pressing assembly 32 can be adjusted by the reverse drive assembly 33. Specifically, when the double-headed telescopic rod 332 is driven down by the lifting cylinder 331, the two connecting rods 333 are synchronously driven to rotate around their respective hinge seats 334, and the inclination angle of the connecting rod 333 gradually increases, and the connecting rod 333 drives the No. 1 roller frame 311 and the No. 2 roller frame 321 correspondingly through the two waist-shaped holes 3331, so that the material supporting assembly 31 is lowered as a whole, and the material pressing assembly 32 is raised as a whole, and the relative height spacing between the material supporting assembly 31 and the material pressing assembly 32 is increased. On the contrary, when the lifting cylinder 331 drives the double-headed telescopic rod 332 to rise, the relative height spacing between the material supporting assembly 31 and the material pressing assembly 32 is reduced.

[0045] like Figure 1 and Figure 4 As shown, in order to facilitate the guidance of the cloth 71 and the film material 72 for compounding, in this embodiment, two cloth guide rollers 12 are horizontally rotatably installed on the frame 1 between the cloth guiding mechanism 3 and the compounding roller group 6; two film guide rollers 11 are also horizontally rotatably installed on the frame 1 between the film material guiding mechanism 4 and the compounding roller group 6.

[0046] Before rolling and laminating, the cloth 71 and the film material 72 can be Figure 4 The conveying direction shown is wound in the device, and its specific conveying direction is not described here; during the winding process, in order to facilitate the passage of the cloth 71 and the film material 72, the cover 43 can be removed, and the relative height distance between the supporting assembly 31 and the pressing assembly 32 can be increased by the reverse driving assembly 33. Figure 4After passing through the direction shown, the height difference between the supporting assembly 31 and the pressing assembly 32 is reduced, so that the supporting roller 312 supports the cloth 71, and the pressing roller 322 presses down on the cloth 71, and the cloth 71 section located between the two pressing rollers 322 is pressed onto the distribution surface of the entire exhaust contact 23. In addition, the film material guiding mechanism 4 descends synchronously with the pressing assembly 32, and can also press the film, and then the covering cover 43 is covered again, and the covering cover 43 plays the role of gathering air and keeping warm.

[0047] During roller lamination, Figure 4 In the process, the cloth 71 and the film material 72 are conveyed from right to left as a whole. During the conveying process, the pressurized hot air discharged from the exhaust contacts 23 distributed in the array is evenly distributed and blown to the cloth 71, so that the cloth 71 material section conveyed between the two pressing rollers 322 is bulging, and the two groups of side tensioning conveying components 5 distributed in the conveying direction before and after the buffer bellows synchronously perform lateral tensioning on the cloth 71 material section, so that the wrinkles on the cloth 71 can be effectively eliminated, and the problem of insufficient lateral opening of the cloth 71 can be solved. The cloth 71 itself has good air permeability. By blowing the pressurized hot air through the cloth 71, the cloth 71 can be quickly and effectively heated, thereby reducing the temperature between the preheated film material 72 and the cloth 71. At the same time, because of the air permeability of the fabric 71, the pressurized hot air can pass through the fabric 71 and have a certain inflation effect on the film material 72, thereby eliminating the possible wrinkles of the film material 72 and synchronously heating the film material 72, so that the preheated film material 72 can be effectively insulated to avoid the rapid loss of heat. In summary, through the above comprehensive effects, the wrinkles existing in the fabric 71 and the film material 72 during roller compounding are reduced, and the fluidity and plasticity of the film material 72 itself are effectively maintained to ensure its hot pressing viscosity, thereby comprehensively improving the composite strength and quality of the waterproof composite geotextile after composite molding.

[0048] The preheated cloth 71 continues to bypass the two cloth guide rollers 12 to reach the composite roller group 6, and the heat-insulated film material 72 continues to bypass the two film guide rollers 11 to reach the composite roller group 6, and the cloth 71 and the film material 72 complete hot pressing composite molding at the composite roller group 6.
