Description

Technical Field

[0001] This application relates to the field of waterproof membrane production equipment, and in particular to a multi-layer waterproof membrane processing apparatus. Background Technology

[0002] Waterproof membranes, as an important building waterproofing material, are mainly used in building walls, roofs, tunnels, highways, landfills, and other scenarios to resist the leakage of external rainwater and groundwater, ensuring the waterproofing effect of building structures and foundations. Waterproof membranes are flexible, can be rolled into rolls, are easy to install, and can cover surfaces of different shapes, making them the primary protective barrier for engineering waterproofing.

[0003] There are many types of waterproof membranes available to meet the waterproofing requirements of different scenarios and needs. Some waterproof membranes need to be combined with non-woven fabrics and other composite layers to improve their performance and applicability. The addition of non-woven fabrics can enhance the tensile strength, abrasion resistance, and aging resistance of waterproof membranes, while improving their weather resistance and durability, making them more suitable for long-term use in various environments.

[0004] Regarding the aforementioned technologies, the inventors believe that current waterproof membranes require a multi-layer composite structure, generally including a first extruded layer, a mesh fabric, a second extruded layer, and a non-woven fabric. However, it is difficult to achieve a multi-layer composite structure through the current one-step composite method. Summary of the Invention

[0005] In order to achieve the composite effect of waterproof membrane in one step and improve the production efficiency of multi-layer waterproof membrane, this application provides a multi-layer waterproof membrane processing device.

[0012] Optionally, a heating assembly is provided between the three-roll pressing section and the two-roll composite section. The heating end of the heating assembly is opposite to the side of the first composite roller away from the second composite roller, and the heating width of the heating assembly is not less than the width of the mesh fabric.

[0013] Optionally, the heating assembly includes a hot air blower, and a hot air outlet is provided on one side of the hot air blower and the first composite roller.

[0027] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a multi-layer waterproof membrane processing apparatus. (Refer to...) Figure 1 , Figure 2 A multi-layer waterproof membrane processing device includes a first support frame 1, a first support platform 11 horizontally arranged on the first support frame 1, and a mesh fabric output roller 12 arranged on the first support platform 11. The mesh fabric is located on the mesh fabric output roller 12 and is output through the mesh fabric output roller 12. A first tension controller 121 is arranged on the mesh fabric output roller 12 to control the rotation speed of the mesh fabric output roller 12, thereby controlling the tension of the mesh fabric output by the mesh fabric output roller 12.

[0031] A traction roller 13 is also provided on the first support platform 11. The traction roller 13 is connected to the mesh fabric output roller 12, thereby pulling the mesh fabric out of the mesh fabric output roller 12. The traction roller 13 is signal-connected to the first tension controller 121. The tension signal generated by the traction roller 13 is fed back to the first tension controller 121, which then adjusts the rotational speed of the mesh fabric output roller 12 to regulate the output of the mesh fabric, thereby adjusting the tension of the mesh fabric located between the traction roller 13 and the mesh fabric output roller 12.

[0032] A second support frame 2 is provided on one side of the first support frame 1. A three-roll pressing part 3 is provided on the second support frame 2. A two-roll composite part 4 is provided on the side of the three-roll pressing part 3 away from the first support frame 1. A cooling component 5 is provided on the side of the two-roll composite part 4 away from the three-roll pressing part 3.

[0033] Reference Figure 3 , Figure 4A first extrusion die 31 is provided inside the three-roll pressing section 3, and a second extrusion die 41 is provided inside the two-roll compound section 4. The first extruded layer produced by the first extrusion die 31 is pressed together with the mesh cloth by the three-roll pressing section 3, and the mesh cloth supports the first extruded layer produced by the first extrusion die 31.

[0034] The first extruded layer, which is coated with a mesh fabric, is laminated by the two-roll laminating section 4, and the first extruded layer and the second extruded layer are laminated together. A nonwoven fabric output roller 6 is also provided at the tail end of the two-roll laminating section 4. The nonwoven fabric output roller 6 laminates the nonwoven fabric to the side of the second extruded layer away from the first extruded layer through the two-roll laminating section 4.

[0035] Reference Figure 2 , Figure 3 The first support frame 1 is rotatably connected to a first guide roller 14 on the side near the three-roll pressing part 3. After being guided by the first guide roller 14, the mesh fabric extends toward one side of the three-roll pressing part 3. The bottom end of the second support frame 2 is rotatably connected to a first flattening roller 21, which flattens the mesh fabric flowing from the first guide roller 14.

[0036] The rotation direction of the traction roller 13 is opposite to that of the mesh fabric output roller 12. The rotation direction of the first steering roller 14 is the same as that of the mesh fabric output roller 12, and the rotation direction of the first flattening roller 21 is the same as that of the mesh fabric output roller 12. The side of the mesh fabric closest to the center of the mesh fabric output roller 12 is the first side of the mesh fabric, and the side of the mesh fabric away from the center of the mesh fabric output roller 12 is the second side of the mesh fabric. The outer wall of the first steering roller 14 abuts against the first side of the mesh fabric, and the first flattening roller 21 abuts against the first side of the mesh fabric.

[0037] The three-roll pressing section 3 includes a first pressure roller 32 and a second pressure roller 33 that are rotatably connected to each other on the second support frame 2. The first pressure roller 32 and the second pressure roller 33 are arranged along the height direction. The first pressure roller 32 is located below the first extrusion die 31, and the second pressure roller 33 is located above the first extrusion die 31.

[0038] The rotation direction of the first pressure roller 32 is opposite to that of the first flattening roller 21, and the rotation direction of the second pressure roller 33 is the same as that of the first flattening roller 21. Therefore, the rotation directions of the first pressure roller 32 and the second pressure roller 33 are opposite. The first pressure roller 32 abuts against the second side of the mesh fabric, and the second pressure roller 33 abuts against the first side of the mesh fabric. A first composite channel is formed between the first pressure roller 32 and the second pressure roller 33. The extrusion end of the first extrusion die 31 is opposite to the first composite channel, and the mesh fabric passes through the interior of the first composite channel.

[0039] The first extrusion die 31 presses the first extruded layer onto the mesh fabric under the action of the first pressure roller 32 and the second pressure roller 33. Through the holes in the mesh fabric, the first extruded layer can be evenly located on both sides of the mesh fabric, thereby supporting the first extruded layer through the mesh fabric.

[0040] A first cooling roller 34 is provided above the second pressure roller 33. The first cooling roller 34 is rotatably connected to the second support frame 2. The rotation direction of the first cooling roller 34 is opposite to the rotation direction of the mesh cloth output roller 12, so that the rotation direction of the first cooling roller 34 is opposite to the rotation direction of the second pressure roller 33. The outer wall of the first cooling roller 34 abuts against the second side of the mesh cloth.

[0041] Reference Figure 1 , Figure 4 The two-roll composite section 4 includes a first composite roller 42 and a second composite roller 43 arranged opposite to each other along the height direction. The first composite roller 42 is located above the second composite roller 43 and above the second extrusion die 41, while the second composite roller 43 is located below the second extrusion die 41.

[0042] The rotation direction of the first composite roller 42 is opposite to that of the mesh fabric output roller 12, and the rotation direction of the second composite roller 43 is the same as that of the mesh fabric output roller 12, so that the rotation directions of the first composite roller 42 and the second composite roller 43 are opposite. A second composite channel is formed between the first composite roller 42 and the second composite roller 43. The extrusion end of the second extrusion die 41 is opposite to the second composite channel. The first extruded layer and the mesh fabric, which are pressed together in the early stage, pass through the interior of the second composite channel and are composited with the second extruded layer.

[0043] The nonwoven fabric output roller 6 is located on the side of the second composite roller 43 opposite to the first pressure roller 32, and the rotation direction of the nonwoven fabric output roller 6 is opposite to the rotation direction of the mesh fabric output roller 12. A second flattening roller 44 is arranged below the second composite roller 43. The rotation direction of the second flattening roller 44 is opposite to the rotation direction of the nonwoven fabric output roller 6. The nonwoven fabric output from the nonwoven fabric output roller 6 is flattened by the second flattening roller 44 and then fed into the second composite roller 43 to be composited with the mesh fabric with the first extrusion layer from the first composite roller 42.

[0044] A second tension controller 61 is provided on the nonwoven fabric output roller 6. The second tension controller 61 controls the rotation of the nonwoven fabric output roller 6, thereby controlling the tension of the nonwoven fabric located between the nonwoven fabric output roller 6 and the second flattening roller 44.

[0045] The first extrusion layer is laminated onto the nonwoven fabric through the first extrusion die 31. The mesh fabric laminated with the first extrusion layer enters the interior of the second composite channel. The second extrusion layer is pressed onto one side of the first extrusion layer through the second extrusion die 41. The nonwoven fabric is laminated onto the side of the second extrusion layer away from the first extrusion layer through the first composite roller 42 and the second composite roller 43.

[0046] A heating assembly 7 is also provided above the first composite roller 42, and the heating assembly 7 is fixed on the second support frame 2. The heating assembly 7 includes a hot air blower 71, the hot air outlet of the hot air blower 71 is positioned facing the side close to the first composite roller 42, and the air outlet of the hot air blower 71 is directed towards the side of the first composite roller 42. The width of the hot air outlet of the hot air blower 71 is not less than the width of the first extruded layer on the first composite roller 42. Thus, the hot air blower 71 can heat the composite of the first extruded layer and the mesh fabric, thereby improving the composite effect.

[0047] Reference Figure 1 , Figure 5 The cooling assembly 5 includes a cooling bracket 51, on which a plurality of second cooling rollers 52 are disposed opposite to each other, and the second cooling rollers 52 are rotatably connected to the cooling bracket 51. The second cooling rollers 52 include an active cooling roller 521 and a driven cooling roller 522, and a plurality of active cooling rollers 521 and driven cooling rollers 522 are disposed opposite to each other, and are arranged sequentially along the conveying direction of the roll material.

[0048] A synchronous motor 523 is provided at the position of the cooling bracket 51 relative to the active cooling roller 521, and the synchronous motors 523 of the multiple active cooling rollers 521 drive the active cooling rollers 521 to rotate at the same speed, so that the multiple second cooling rollers 52 can drive the roll material to move synchronously, ensuring that the appearance of the roll material is not overstretched and ensuring tension balance.

[0049] The mesh fabric on the mesh fabric output roller 12 is output under the drive of the traction roller 13. The mesh fabric enters the first flattening roller 21 through the traction roller 13. The first flattening roller 21 flattens the mesh fabric and then enters the right side of the first pressure roller 32. The first extrusion layer is laminated onto the mesh fabric through the first extrusion die 31. The first extrusion layer extruded from the first extrusion die 31 is laminated onto the mesh fabric through the first pressure roller 32 and the second pressure roller 33. The laminated mesh fabric with the first extrusion layer is output from the left side of the second pressure roller 33 and enters the right side of the first cooling roller 34 located at the top of the second pressure roller 33 for cooling and lamination.

[0050] After being cooled by the first cooling roller 34, the mesh fabric with the first extruded layer is output above the first composite roller 42. The heating component 7 located above the first composite roller 42 heats the mesh fabric with the first extruded layer to improve the composite effect. The heated mesh fabric with the first extruded layer is input from the left side of the first composite roller 42 and the second extrusion die 41 presses the second extruded layer onto one side of the first extruded layer.

[0051] The nonwoven fabric is output to the left side of the second composite roller 43 by the nonwoven fabric output roller 6, and the nonwoven fabric is composited with the second extrusion layer between the first composite roller 42 and the second composite roller 43, so that the nonwoven fabric located at the position of the first composite roller 42 and the second composite roller 43 is composited on the side of the second extrusion layer away from the first extrusion layer, and then the roll material is composited by the first composite roller 42 and the second composite roller 43.

[0052] After lamination, the roll material is transported to the interior of the cooling assembly 5 for cooling. The active cooling roller 521, controlled by the synchronous motor 523, drives the driven cooling roller 522 to rotate, so that the rotation speed of multiple active cooling rollers 521 is the same, ensuring that the appearance of the roll material is not overstretched and ensuring tension balance.
