Description

Technical Field

[0001] This application belongs to the technical field of waterproof membrane production equipment, specifically relating to equipment for forming reinforced waterproof membranes. Background Technology

[0002] Most reinforced waterproof membrane production involves a double-coating process. Specifically, after pre-impregnating the base fabric, a base material coating process is performed, followed by a fabric coating process. Finally, the double-coated base fabric is cooled and solidified using cooling water. It is evident that traditional reinforced waterproof membrane production lines require at least two independent coating machines to perform the secondary coating on the base fabric, occupying a significant number of production line positions. Furthermore, the two coating processes require intermediate transfer, resulting in a longer production line and lower space utilization. Utility Model Content

[0003] In view of at least one of the above-mentioned defects or deficiencies in the prior art, this application provides a membrane forming equipment with a lining, which improves the integration of the equipment, realizes an integrated process of coating, reduces the number of workstations occupied by the equipment, and improves the utilization rate of production line space.

[0004] To achieve the above objectives, this application provides a reinforced waterproof membrane forming device, the reinforced waterproof membrane forming device comprising:

[0005] frame;

[0006] A base material extrusion roller assembly is disposed in the frame and is used to introduce the fabric for coating the base material;

[0007] A fabric extrusion roller assembly is disposed in the frame and is used to introduce the lining fabric exported from the base material extrusion roller assembly for application.

[0008] A cooling roller is disposed in the frame and is used to cool the fabric extruded from the fabric extrusion roller assembly.

[0009] In some embodiments, the base material extrusion roller assembly, the fabric extrusion roller assembly, and the cooling roller are arranged sequentially at intervals.

[0010] In some embodiments, the base material extrusion roller assembly includes:

[0011] Two base material pressure rollers are arranged in parallel intervals along the transverse direction;

[0012] Multiple base material baffles are disposed on the top of the two base material pressure rollers and are arranged sequentially at intervals along the axial direction of the base material pressure rollers. The two adjacent base material baffles and the two base material pressure rollers together define the base material accumulation groove.

[0013] In some embodiments, the fabric extrusion roller assembly includes:

[0014] Two fabric pressure rollers are arranged in parallel intervals along the transverse direction;

[0015] Multiple fabric baffles are disposed on top of the two fabric pressure rollers and arranged sequentially at intervals along the axial direction of the fabric pressure rollers. The two adjacent fabric baffles and the two fabric pressure rollers together define a fabric accumulation groove.

[0016] In some embodiments, one of the two fabric rollers is configured as a first roller for introducing the first coating, and the other is configured as a second roller for introducing the second coating.

[0017] In some embodiments, both the base material extrusion roller assembly and the fabric extrusion roller assembly include a first pressure roller and a second pressure roller arranged in parallel at intervals. The PVC-coated waterproof roll forming equipment also includes a pressure roller adjustment mechanism disposed on the frame and used to adjust the distance between the first pressure roller and the second pressure roller.

[0018] In some embodiments, both the base material extrusion roller assembly and the fabric extrusion roller assembly include a first pressure roller and a second pressure roller arranged in parallel at intervals. The PVC-coated waterproof roll forming equipment also includes a pressure roller drive mechanism mounted on the frame for driving the first pressure roller and / or the second pressure roller to rotate.

[0019] In some embodiments, the reinforced waterproof membrane forming equipment further includes:

[0020] A fabric limiting device is provided in the frame and is used to limit the lateral movement of the fabric as it is introduced into the extrusion roller assembly.

[0021] In some embodiments, the tarpaulin limiting device includes:

[0022] Two limiting components are arranged at intervals along the lateral direction;

[0023] A lateral movement mechanism is used to drive the limiting member to move laterally to adjust the lateral distance between the two limiting members.

[0024] In some embodiments, the traversing mechanism includes:

[0025] The transverse guide rail forms a sliding fit with the limiting member;

[0026] The lead screw is screwed to the limiting member;

[0027] A rotation drive assembly is used to drive the lead screw to rotate so as to move the limiting member along the transverse guide rail.

[0028] In the PVC-coated waterproof membrane forming equipment of this application, by integrating the base material extrusion roller assembly, the fabric extrusion roller assembly, and the cooling roller onto the same frame, the coating, lamination, and cooling processes can be integrated into a single machine. This helps to shorten the production line length of the PVC-coated waterproof membrane, reduce the floor space occupied by the production line, and thus improve the space utilization rate of the production line. In addition, thanks to the significantly reduced distance between the base material extrusion roller assembly and the fabric extrusion roller assembly, the running distance of the fabric between the two coating processes is greatly reduced, achieving better connection between the two processes. This avoids the temperature drop of the fabric due to excessive running distance, which could affect the bonding force between the base material and the fabric, effectively improving the product yield.

[0029] Other features and advantages of the embodiments of this application will be described in detail in the following detailed description section. Attached Figure Description

[0034] Detailed Implementation

[0035] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0036] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0037] like Figure 1 and Figure 2As shown in the exemplary embodiment of this application, a PVC-coated waterproof roll forming apparatus is provided. The apparatus includes a frame 1, a base material extrusion roller assembly 2, a fabric extrusion roller assembly 3, and a cooling roller 4. The base material extrusion roller assembly 2 is disposed in the frame 1 and is used to introduce the base fabric C for coating with the base material; the fabric extrusion roller assembly 3 is disposed in the frame 1 and is used to introduce the base fabric C exported from the base material extrusion roller assembly 2 for fabric application; the cooling roller 4 is disposed in the frame 1 and is used to cool the base fabric C exported from the fabric extrusion roller assembly 3.

[0038] Reference Figure 2 The pre-impregnated fabric C is introduced from one end of the frame 1 into the base material extrusion roller assembly 2. Under the extrusion of the base material extrusion roller assembly 2, the base material is coated on both sides of the fabric C to form a base material layer. Then, the fabric C with the base material layer is exported from the base material extrusion roller assembly 2 and introduced into the fabric extrusion roller assembly 3. Under the extrusion of the fabric extrusion roller assembly 3, the fabric is attached to the base material layer to form a double-layer fabric structure with fabric and base material. Finally, the double-layer fabric is exported from the fabric extrusion roller assembly 3 and passes around the cooling roller 4. The cooling roller 4 is used to cool and shape the double-layer fabric.

[0039] As can be seen, the PVC-coated waterproof membrane forming equipment of this exemplary embodiment integrates the base material extrusion roller assembly 2, the fabric extrusion roller assembly 3, and the cooling roller 4 onto the same frame 1. This allows for an integrated process flow of coating, laminating, and cooling within the same machine, which helps to shorten the production line length of PVC-coated waterproof membranes, reduce the floor space occupied by the production line, thereby improving the space utilization rate of the production line and saving equipment energy consumption. In addition, thanks to the significantly reduced distance between the base material extrusion roller assembly 2 and the fabric extrusion roller assembly 3, the running distance of the PVC-coated fabric between the two coating processes is greatly reduced, achieving better connection between the two processes. This avoids the temperature drop of the PVC-coated fabric due to excessive running distance, which would affect the bonding force between the base material and the fabric, thereby effectively improving the product yield.

[0040] The base material extrusion roller assembly 2, the fabric extrusion roller assembly 3, and the cooling roller 4 are arranged sequentially in the frame 1, and can be arranged horizontally, vertically, or randomly. For example, as shown in the diagram, the base material extrusion roller assembly 2, the fabric extrusion roller assembly 3, and the cooling roller 4 are arranged vertically at intervals, thus controlling the overall equipment layout in the vertical space, making the structure more compact, not occupying too many horizontal workstations, and reducing the floor space. Moreover, referring to... Figure 2 The fabric C is conveyed from top to bottom, which makes the base material and fabric coating on both sides of the fabric C more uniform.

[0041] Reference Figure 2 The base material extrusion roller assembly 2 in this embodiment may include:

[0042] Two base material pressure rollers 201 are arranged in parallel intervals along the transverse direction;

[0043] Multiple base material baffles 202 are disposed on the top of two base material pressure rollers 201 and are arranged sequentially at intervals along the axial direction of the base material pressure rollers 201. Two adjacent base material baffles 202 and two base material pressure rollers 201 together define the base material accumulation groove 203.

[0044] The base material accumulation groove 203 is used to accumulate the base material for coating, and the base material baffle 202 is set to prevent the base material from flowing away from the two lateral ends of the base material pressure rollers 201. This design enables the base material extrusion roller assembly 2 to have a base material storage function. The fabric C is introduced into the extrusion gap between the two base material pressure rollers 201 through the base material accumulation groove 203. At this time, the base material can adhere to both sides of the fabric C, and then pass through the two base material pressure rollers 201 for extrusion and uniform distribution, thereby realizing the coating of the base material.

[0045] In this embodiment, two base material baffles 202 can be provided, respectively disposed at both ends of the two base material pressure rollers 201, for stopping the base material. Simultaneously, the two base material baffles 202 can also define the fabric's movement position in the width direction, effectively preventing lateral displacement of the fabric before extrusion. Of course, multiple rolls of fabric can be fed into the two base material pressure rollers 201 for extrusion. Correspondingly, multiple base material baffles 202 can be provided on the two base material pressure rollers 201, arranged sequentially and at intervals along the axial direction of the base material pressure rollers 201, thereby defining multiple base material accumulation grooves 203. Multiple rolls of fabric can be fed from the multiple base material accumulation grooves 203 between the two base material pressure rollers 201, achieving simultaneous base material coating of multiple rolls of fabric and improving production efficiency.

[0046] Similarly, refer to Figure 2 The fabric extrusion roller assembly 3 of this embodiment includes:

[0047] Two fabric pressure rollers 301 are arranged in parallel intervals along the transverse direction;

[0048] Multiple fabric baffles 302 are disposed on top of two fabric pressure rollers 301 and are arranged sequentially at intervals along the axial direction of the fabric pressure rollers 301. Two adjacent fabric baffles 302 and two fabric pressure rollers 301 together define the fabric accumulation groove 303.

[0049] The fabric accumulation groove 303 is aligned with the base material accumulation groove 203 and is used to accumulate the fabric for coating. The fabric baffle 302 is provided to prevent the base material from flowing away from the two fabric pressure rollers 301 at their lateral ends. This design enables the fabric extrusion roller assembly 3 to have a fabric storage function. The base fabric C is led out from the base material extrusion roller assembly 2 and enters the fabric accumulation groove 303, and is introduced into the extrusion seam between the two fabric accumulation grooves 303. At this time, the fabric can adhere to the base material layer of the base fabric C, and then pass through the two fabric pressure rollers 301 for extrusion and uniform distribution, thereby achieving the coating of the fabric.

[0050] In this embodiment, two fabric baffles 302 can be provided, respectively disposed at both ends of the two fabric pressure rollers 301, for stopping the fabric. Simultaneously, the two fabric baffles 302 can also define the fabric feeding position in the width direction, effectively preventing lateral displacement of the fabric before compression. Of course, multiple rolls of fabric can be fed into the two fabric pressure rollers 301 for compression. Correspondingly, multiple fabric baffles 302 can be provided on the two fabric pressure rollers 301, arranged sequentially and at intervals along the axial direction of the fabric baffles 302, thereby defining multiple fabric accumulation grooves 303. Multiple rolls of fabric can be simultaneously fed into the multiple fabric accumulation grooves 303, achieving simultaneous coating of multiple rolls of fabric and improving production efficiency.

[0051] Based on the design of the double-fabric pressure roller 301, and referring to Figure 2 One of the two fabric pressure rollers 301 is configured as a first pressure roller for introducing the first coating A, and the other is configured as a second pressure roller for introducing the second coating B. Thus, when the lining fabric C is introduced between the two fabric pressure rollers 301, the first coating A and the second coating B can be introduced from both sides of the lining fabric C respectively, and then adhered to both sides of the lining fabric C, achieving double-sided adhesion. The first coating A and the second coating B can be coatings of the same material or coatings of different materials; this application does not impose any limitation on this.

[0052] In one embodiment, both the base material extrusion roller assembly 2 and the fabric extrusion roller assembly 3 include a first pressure roller and a second pressure roller arranged in parallel at intervals. The waterproof roll forming equipment also includes a pressure roller adjusting mechanism 5 mounted on the frame 1 for adjusting the distance between the first pressure roller and the second pressure roller. Specifically, refer to... Figure 1 The first or second pressure roller is mounted in the frame 1 via a bearing support. The pressure roller adjustment mechanism 5 includes a slide rail disposed in the frame 1. The bearing support and the slide rail form a sliding fit, enabling the first or second pressure roller to move laterally. For example, the first pressure roller is formed as a fixed pressure roller, and the second pressure roller is formed as a movable pressure roller. By moving and adjusting the second pressure roller, the distance between the first and second pressure rollers is adjusted, thereby extruding waterproof membranes of different thicknesses and improving the versatility of the equipment.

[0053] In one embodiment, both the base material extrusion roller assembly 2 and the fabric extrusion roller assembly 3 include a first pressure roller and a second pressure roller arranged in parallel and spaced apart. The waterproof roll forming equipment also includes a pressure roller drive mechanism 6 mounted on the frame 1 for driving the first pressure roller and / or the second pressure roller to rotate. For example, see reference... Figure 1 The first pressure roller is formed as a driven pressure roller, and the second pressure roller is formed as a driving pressure roller. The second pressure roller is driven to rotate by the pressure roller drive mechanism 6. While the fabric C is being introduced, the second pressure roller can drive the first pressure roller to rotate in the opposite direction, so that the fabric C can be continuously introduced between the first pressure roller and the second pressure roller.

[0054] In this embodiment, the pressure roller drive mechanism 6 can be a worm gear reducer. The output end of the worm gear reducer is connected to the shaft end of the first or second pressure roller, thereby driving the first or second pressure roller to rotate. As is known to those skilled in the art, a worm gear reducer is a speed reduction device that uses the meshing of a worm (helical gear) and a worm wheel (spur gear) for transmission. It has the characteristics of compact structure, large transmission ratio, and good self-locking performance. It can convert high-speed input into low-speed, high-torque output, and is suitable for the medium-to-low power continuous operation environment of this application, effectively reducing operating energy consumption. It will not be elaborated further here.

[0055] In one embodiment, such as Figure 1 As shown, the waterproof membrane forming equipment also includes a membrane limiting device 7. The membrane limiting device 7 is installed in the frame 1 and is used to limit the lateral movement of the membrane introduced into the extrusion roller assembly. Specifically, the membrane limiting device 7 includes two limiting members 701 and a lateral movement mechanism. The two limiting members 701 are arranged laterally at intervals and can directly contact the edge of the membrane to form a guide channel, preventing lateral deviation of the membrane. The lateral movement mechanism is used to drive the limiting members 701 to move laterally to adjust the lateral distance between the two limiting members 701, thereby accommodating the introduction of membranes of different widths. Specifically, the lateral movement mechanism includes a transverse guide rail 702, a lead screw 703, and a rotation drive assembly 704. The transverse guide rail 702 is fixed on the frame 1 and slides with the limiting members 701 through a slider or linear bearing to ensure smooth movement of the limiting members 701. Two transverse guide rails 702 can be provided to form a double-rail symmetrical layout to enhance the movement stability of the limiting members 701. The lead screw 703 is screwed to the limiting member 701. When the lead screw 703 rotates, the two limiting members 701 move synchronously in opposite directions to achieve symmetrical adjustment of the spacing. In this embodiment, both ends of the lead screw 703 can be fixed to the frame 1 through bearing seats to avoid bending vibration and ensure transmission accuracy. The rotation drive assembly 704 is used to drive the lead screw 703 to rotate, thereby moving the limiting member 701 along the transverse guide rail 702. It can be automatically controlled by a motor (servo or stepper) or manually operated by a handwheel. The configuration is based on the automation requirements of the equipment during actual assembly, and this application does not limit it.

[0056] Therefore, by rotating the drive assembly 704 (such as a handwheel) to drive the lead screw 703 to rotate, the rotation of the lead screw 703 causes the two limiting parts 701 to move synchronously along the transverse guide rail 702, adjusting the distance between them to accommodate different widths of fabric, ensuring that the fabric will not shift laterally when entering the extrusion rollers, thus guaranteeing the stability of the production process and product quality.
