Description

Technical Field

[0001] This invention belongs to the field of building waterproofing, and in particular relates to a production line equipment for producing waterproof membranes. Background Technology

[0002] The structure of waterproof membrane is generally as follows: Figure 1a , Figure 1b As shown, the waterproof membrane consists of a central base layer 1', adhesive layers 2' bonded to both sides of the base layer 1', and an outermost release liner 3'. During waterproofing construction, the release liner 3' needs to be removed and laid on the concrete substrate, allowing the adhesive layer 2' to react and bond with the concrete. Multiple waterproof membranes are then overlapped to form a large-area waterproof layer. The overlapping area between adjacent membranes is called the overlap edge. Construction specifications require the overlap edge width to be no less than a specified value (generally 80mm). To facilitate construction, manufacturers typically pre-install overlap edges during the production of waterproof membranes, i.e., separate overlap edge release liners 31' are provided at the overlap edge positions on both sides. The release liner 3' consists of two parts: the overlap edge release liner 31' and the main release liner 32'. During construction, only the overlap edge release liner 31' needs to be torn off to overlap the membrane.

[0003] There are many different forms of overlapping edge membranes. Figure 1a The image shows one type of overlapping edge film, where the width of the overlapping edge release film 31' is slightly larger than the width of the adhesive layer it covers. Figure 1b The diagram shows another type of overlapping edge membrane, in which a cut edge 33' for separation is formed between the overlapping edge main isolation membrane 32' and the overlapping edge isolation membrane 31'. Different types of overlapping edge membrane rolls usually correspond to different production equipment and processes. Therefore, we need to consider how to produce waterproof rolls of different models and overlapping edge membrane types on the same set of production equipment, so as to save on equipment purchase costs and reduce the cost of upgrading and replacing the equipment. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a production system that can be compatible with the production of waterproof membranes with various overlapping edge forms, thereby reducing the cost of equipment modification and upgrading.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The production line is compatible with the production of various edge membrane waterproof membranes, including a base layer traction system, two sets of release membrane traction systems located on both sides of the base layer, a scraping mechanism for scraping modified bitumen rubber onto one side of the release membrane to form a rubber layer, a film coating mechanism for pressing the release membrane and the base layer together to form a single-sided semi-finished membrane, a coating and extrusion mechanism for extruding the single-sided semi-finished membrane, modified bitumen rubber and the release membrane on the other side, and two cutting mechanisms located downstream.

[0007] The isolation membrane traction system includes an isolation membrane feeding roller for traction of the main isolation membrane or the isolation membrane, and multiple guide rollers for conveying the isolation membrane downstream.

[0008] The coating mechanism is located downstream of one of the isolation film traction systems, and includes a set of heating coating rollers and cooling rollers arranged adjacent to each other and rotating in opposite directions.

[0009] The coating and extrusion mechanism includes a pair of cooling and shaping rollers arranged on the left and right and rotating in opposite directions. One cooling and shaping roller is used to guide the release film conveyed by the release film traction system on the other side, and the other cooling and shaping roller is used to guide the single-sided semi-finished roll material conveyed by the coating mechanism, and to extrude the release film, the single-sided semi-finished roll material and the asphalt adhesive into shape in the middle gap of the cooling and shaping roller.

[0010] The isolation membrane traction system also includes an overlap edge film feeding roller for traction of the overlap edge isolation membrane and an overlay roller for stacking the main isolation membrane and the overlap edge isolation membrane to form an isolation membrane.

[0011] A feeding adjustment baffle and a heating plate are installed on one side of the scraping mechanism. The heating plate is located in front of the heating oiling roller and is inclined towards the middle gap of the scraping mechanism. The two feeding adjustment baffles are located between the heating plate and the heating oiling roller, with their edges in contact with the roller or heating plate. The space they enclose forms a feeding hopper with a bottom outlet.

[0012] The cooling and shaping roller used to guide the release film on the other side in the coating and extrusion mechanism is an adjustable cooling roller, and the other cooling and shaping roller used to guide the single-sided semi-finished roll material conveyed by the coating mechanism is a fixed cooling roller. The fixed cooling roller is perpendicular to the vertical tangent on the left side of the large roller below.

[0013] The coating mechanism is located downstream of the tire base traction system and the coating mechanism. It includes a pre-pressure roller located above and used to guide the tire base and a coating roller located below and used to guide the release film. The pre-pressure roller and the coating roller are staggered vertically. The highest point of the coating roller is higher than the height of the line connecting the highest points of the cooling roller and the fixed cooling roller, and the lowest point of the pre-pressure roller is lower than the height of the extension line connecting the tangent points of the fixed cooling roller and the coating roller.

[0014] The cutting mechanism includes an L-shaped support fixed next to the guide roller, a left-right adjustment device mounted on the L-shaped support, a front-back adjustment device mounted on the left-right adjustment device, a precision fine-tuning slide mounted on the front-back adjustment device, and a blade fixed on the precision fine-tuning slide.

[0015] The left and right adjustment device includes a transverse linear guide rail fixed along the direction parallel to the guide roller, a transverse slide table that moves on the transverse linear guide rail, a mounting base fixed on the transverse slide table and movable left and right with the transverse slide table, and a drive mechanism for driving the mounting base to slide along the transverse linear guide rail.

[0016] The front-to-back adjustment device includes a longitudinal linear guide rail fixed on the mounting base, a longitudinal slide table that moves along the longitudinal linear guide rail, a cutting blade mounting base fixed on the longitudinal slide table and movable back and forth with the longitudinal slide table, and a drive mechanism for driving the cutting blade mounting base to slide along the longitudinal linear guide rail. The installation directions of the longitudinal linear guide rail and the transverse linear guide rail are perpendicular to each other. The precision fine-tuning slide table is mounted on the cutting blade mounting base, and the blade is fixed to the front end of the precision fine-tuning slide table.

[0017] On the precision micro-adjustment slide, an arc-shaped adjustment plate is fixed at the foremost tip of the blade via a side bracket. A through hole is provided in the middle of the arc-shaped adjustment plate, so that the blade tip protrudes from the middle through hole onto the surface of the arc-shaped adjustment plate.

[0018] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0019] 1. This invention is equipped with two sets of isolation film traction systems and two-directional cutting mechanisms, which can be used to produce according to needs. The guide roller or cutting mechanism of the overlapping edge isolation film on either side can be selected to work or not work, so that waterproof membranes with double-sided or single-sided overlapping edge film or cut edge film can be produced. The same set of equipment can be compatible with the production of waterproof membranes with various overlapping edge forms, saving equipment purchase costs and reducing costs.

[0020] 2. The production process of this invention first applies a coating to the first side of the adhesive material, and then applies a coating to the other side of the adhesive material while simultaneously extruding and molding it. Therefore, this production line combines coating, extrusion and thickness determination in the same process, and the material is cut in two separate steps, making it easier to control the process and ensure that the thickness of the adhesive layer on both sides is consistent.

[0021] 3. This invention is applicable to the production of waterproof membranes with a core-shell structure and a hot-pressed cross-linked polymer base. The extrusion process of the coating and extrusion mechanism allows the adhesive to fully penetrate the base fabric, enhancing the adhesion between the adhesive layer and the base, and preventing the product from delaminating. Moreover, the soft base fabric is first coated with the adhesive and then extruded, making it less prone to wrinkles. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] Example 1

[0033] Please see Figure 2 As shown, the present invention discloses a production system for waterproof membrane, which includes a base layer traction system, two sets of release film traction systems, a scraping mechanism, a film covering mechanism, a coating and extrusion mechanism, and two cutting mechanisms.

[0034] Specifically, the tire base traction system includes a tire base discharge roller 11 and multiple guide rollers 12 for guiding the tire base 1' to be conveyed downstream.

[0035] Each set of isolation membrane traction system includes an isolation membrane feeding roller 21 for traction of the main isolation membrane 32' or isolation membrane 3', an overlap edge film feeding roller 22 for traction of the overlap edge isolation membrane 31', and a roller for pressing the main isolation membrane 32' and the overlap edge isolation membrane 31' together. Figure 1a The stacking roller 23, which forms the isolation membrane 3', and the plurality of guide rollers 24 for conveying the isolation membrane 3' downstream.

[0036] The coating mechanism is positioned downstream of one of the sealing film traction systems in the conveying direction, such as... Figure 7 As shown, it includes a set of heating and cooling rollers 31 and 32 arranged adjacent to each other and rotating in opposite directions. A feeding adjustment baffle 33 and a heating plate 34 are installed on the feeding side of the scraping mechanism. The heating plate 34 is located in front of the heating and cooling rollers 31 and is inclined towards the middle gap of the scraping mechanism. The two feeding adjustment baffles 33 are located between the heating plate 34 and the heating and cooling rollers 31, and their edges are respectively in contact with the shape of the rollers or the heating plate 34. The space enclosed forms a feeding hopper with a bottom outlet. The molten modified asphalt coating is poured into the isolation membrane 3' passing below through the feeding hopper for the first feeding. The isolation membrane 3', which is covered with modified asphalt coating, is then conveyed from the gap between the heating and cooling rollers 31 and 32. During the rotation of the heating and cooling rollers 31, excess adhesive can be scraped off at the same time, thereby achieving uniform scraping of the modified asphalt adhesive to form an adhesive layer 2'.

[0037] Cooling water is introduced into the interior of the cooling roller 32, and high-temperature heat-conducting oil is introduced into the interior of the heating oiling roller 31 to heat the asphalt. A heating roller adjustment device 36 is provided on each of the left and right sides of the heating oiling roller 31. The device has an automatic motor adjustment function and a manual adjustment function to adjust the height of the heating oiling roller 31. The thickness of the roll material is controlled by adjusting the roller spacing.

[0038] The heating plate 34 does not generate heat under normal circumstances, and is only energized to heat up when rapid heating is required, such as during temporary shutdowns, to prevent asphalt from slowly solidifying on the heating plate 34. Rotating the width adjustment handle 35 moves the two feeding adjustment baffles 33 closer to the center or further away from the sides, thereby adjusting the feeding width.

[0039] The coating mechanism 4 is located downstream of the tire base traction system and the scraping mechanism in the conveying direction, and is used to press the pulled tire base 1' together with the release film 3' coated with the rubber layer 2', see... Figure 3 The coating mechanism includes a pre-pressure roller 41 for guiding the base layer 1' and a coating roller 42 for guiding the release film 3'. The pre-pressure roller 41 and the coating roller 42 are staggered vertically, and their axes are not on the same vertical line. The base layer 1' wraps around the lower part of the pre-pressure roller 41 and enters the gap between the pre-pressure roller 41 and the coating roller 42. The release film 3' is close to the upper part of the coating roller 42 and enters the gap between the pre-pressure roller 41 and the coating roller 42. The release film 3' and the coating roller 42 coincide at the intersection point (point A in the figure). The base layer 1', the rubber layer 2' and the release film 3' are pressed together at point A to form a semi-finished single-sided roll material. The single-sided roll material is pulled to the downstream coating and extrusion mechanism.

[0040] See Figure 8As shown, the coating and extrusion mechanism includes a pair of cooling and shaping rollers arranged side by side and rotating in opposite directions. The two cooling and shaping rollers are the same size and their axes are on the same horizontal plane. Cooling water is circulated through the two cooling rollers. The left side is an adjustable cooling roller 51 used to pull another release film 3', and the right side is a fixed cooling roller 52 used to pull the single-sided semi-finished roll material conveyed by the laminating mechanism 4. Two width adjustment baffles 53 are located above the middle of the two cooling rollers, and their bottoms form an edge shape that fits into the arc of the two rollers, so that the two width adjustment baffles 53 and the upper surface of the two rollers together form a feeding space. The width adjustment baffles 53 can be adjusted by moving closer to the middle or further away from the sides.

[0041] The position of the fixed cooling roller 52 is fixed and kept perpendicular to the vertical tangent on the left side of the large roller 55 below, which facilitates thickness adjustment and does not affect the wiring effect, thus avoiding poor bonding effect of the roll material. Thickness adjustment devices 54 are installed on the left and right sides of the adjustable cooling roller 51. The device has automatic motor adjustment function and manual adjustment function. By adjusting the left and right position of the adjustable cooling roller 51, the width of the gap between the rollers can be adjusted, thereby controlling the thickness of the finished roll material.

[0042] Molten modified bitumen is poured between the release membrane 3' and the single-sided roll material for a second feeding. Two cooling and shaping rollers rotate to carry the release membrane 3' and the single-sided roll material into the gap between the rollers and convey them downwards. During the process, the bitumen material coated on the surface is also carried to the middle gap. During the conveying process, the release membrane 3', the bitumen material and the single-sided roll material are not only squeezed together at the extrusion point B, but the material sandwiched in the middle is also compressed to a certain thickness to form another layer of material 2'. Finally, the double-sided waterproof roll material is extruded out.

[0043] In this embodiment, the base layer 1' is a core-skin structure hot-pressed cross-linked polymer base fabric, which is a relatively soft material and not as heat-resistant as other base fabrics such as PET. The extrusion process of the coating and extrusion mechanism allows the adhesive to fully penetrate the base fabric, enhancing the adhesion between the adhesive layer and the base fabric, and preventing the delamination of the finished roll product.

[0044] Because the rubber compound does not easily penetrate the tire base fabric at low temperatures, and in order to avoid high-temperature deformation of the tire base, cooling water is circulated inside the cooling and shaping roller, and the cooling and shaping roller rotates at a relatively fast speed. As soon as the high-temperature asphalt material is poured onto the tire base fabric, it is instantly carried into the middle gap and quickly cooled, squeezed and shaped, so as to avoid damage and deformation of the tire base material due to heat.

[0045] The system is equipped with a manual or automatic control adjustment device for adjusting the distance between each roller. For example, the thickness adjustment device 54 is used to adjust the left and right positions of the adjustable cooling roller 51 and control the extrusion thickness of the rubber layer. In this embodiment, the distance between the closest adjacent points of the two cooling and shaping rollers is set to be less than 0~0.5mm of the overall thickness of the product.

[0046] The pre-pressing roller 41 and the coating roller 42 are also equipped with adjusting devices to achieve vertical adjustment, see Figure 3 As shown, the highest point of the coating roller 42 is slightly higher than the height of the line connecting the highest points of the cooling roller 32 and the fixed cooling roller 52, so that when the release film 3' passes through the coating roller 42, the stress point of the release film 3' is at the point of action A; the lowest point of the pre-pressure roller 41 is adjusted to be slightly lower than the height of the extension line of the line connecting the tangent point between the fixed cooling roller 52 and the coating roller 42, so that the stress point of the tire base 1' is also at the point of action A. The point of action A is also the bonding point where the release film 3' and the tire base 1' are bonded together, avoiding the bonding point from falling at the tangent point C of the fixed cooling roller 52 which is far away, so that the distance between the coating point D and the bonding point is not too long, the production process is more stable, and it is not easy to shake or wrinkle.

[0047] A row of spray pipes 43 is set between the scraping point D and the bonding point A. When the high-temperature adhesive layer 2' is scraped onto the release liner 3', in order to prevent the heat-sensitive release liner 3' from deforming due to heat, it is necessary to spray and cool the other side of the release liner 3' through the spray pipes 43. However, spraying will accelerate the cooling speed of the adhesive on the release liner 3' during the conveying process. Therefore, the bonding point falls at point A. Compared with point C, the bonding point A is closer to the scraping point D. The base layer 1' can be bonded to the adhesive layer 2' of the release liner 3' as soon as possible before the adhesive hardens.

[0048] The extruded roll material is pulled by multiple guide rollers towards the cutting mechanism 6 for cutting the overlapping edges, see... Figure 4 and Figure 5 As shown, the cutting mechanism 6 includes an L-shaped support 61 fixed next to the guide roller, a left-right adjustment device mounted on the L-shaped support 61, a front-back adjustment device mounted on the left-right adjustment device, a precision fine-tuning slide 635 mounted on the front-back adjustment device, and a blade 64 fixed on the precision fine-tuning slide 635.

[0049] See Figure 4 and Figure 5 As shown, the left and right adjustment device includes a transverse linear guide rail 621 fixed along the long side parallel to the L-shaped support base, a transverse slide 622 that moves on the transverse linear guide rail 621, a mounting base 623 fixed on the transverse slide 622 and movable left and right with the transverse slide 622, and a drive mechanism for driving the mounting base 623 to slide along the transverse linear guide rail 621.

[0050] The front and rear adjustment device includes a longitudinal linear guide rail 631 fixed on the mounting base 623 (the longitudinal linear guide rail 631 and the transverse linear guide rail 621 are perpendicular to each other in installation direction), a longitudinal slide 632 that moves along the longitudinal linear guide rail 631, a cutting blade mounting base 633 fixed on the longitudinal slide 632 and movable back and forth with the longitudinal slide 632, and a drive mechanism for driving the cutting blade mounting base 633 to slide along the longitudinal linear guide rail 631.

[0051] A precision fine-tuning slide 635 is mounted on a cutting blade mounting base 633. The blade 64 is fixed on the precision fine-tuning slide 635. The displacement direction of the precision fine-tuning slide 635 is the same as the displacement adjustment direction of the front and rear adjustment device. An arc-shaped adjustment plate 65 is fixed on the precision fine-tuning slide 635 at the foremost point of the blade 64 via a side bracket 66. A through hole is provided in the middle of the arc-shaped adjustment plate 65, which allows the blade tip to protrude from the surface of the arc-shaped adjustment plate 65 through the middle through hole.

[0052] The drive mechanism uses a hand-cranked lead screw assembly. The drive mechanism for the left-right adjustment device includes a lead screw 624 connected to one end of the mounting base 623 and a handwheel for rotating the lead screw 624. The drive mechanism for the front-back adjustment device includes a lead screw 634 connected to one end of the cutting blade mounting base 633 and a handwheel for rotating the lead screw 634. The handwheels shown in the figures are not shown. Other drive mechanisms, such as electric actuators or pneumatic actuators, commonly used by those skilled in the art, can also be employed.

[0053] During the transmission process, when the roll material passes through the cutting mechanism 6, the blade 64 cuts the release film on the surface of the roll material. After the entire release film 3' is cut, it is naturally divided from the cut edge 33' to form the main release film 32' and the overlapping release film 31', forming the final release film. Figure 1b The image shows a finished waterproof membrane roll with a pre-reserved overlapping edge release membrane.

[0054] The left and right adjustment device is used to adjust the cutting position of the blade 64 on the roll material. Turning the handwheel moves the blade 64 along the width of the roll material, thus determining the cutting position of the release film on the roll material according to the pre-reserved width of the overlap edge. Figure 2 The cutting edge is positioned at 33'. The front and rear adjustment device and the precision fine-tuning slide 635 are used to control the cutting depth. After coarse adjustment to the approximate position by the front and rear adjustment device, fine adjustment is made by the precision fine-tuning slide 635. The arc-shaped adjustment plate 65 at the front end of the blade tip can help control the cutting depth. Before cutting, the surface of the arc-shaped adjustment plate 65 is adjusted so that it just touches the surface of the roll material. In this way, the length of the blade tip protruding from the arc-shaped adjustment plate 65 is just right so that the inner rubber layer and base material will not be damaged during cutting.

[0055] The blade tip of the cutting mechanism 6 can be adjusted backward to move it away from the surface of the roll material. In this way, the cutting mechanism 6 will not perform cutting operations. The main release film 32' can then be placed on the release film feeding rollers 21 of the release film traction system on both sides, thus producing products such as... Figure 1a The waterproof membrane shown.

[0056] When the blade tip is adjusted forward to initiate the cutting mechanism 6, the isolation film 3' is placed onto the isolation film traction system's isolation film feeding rollers 21 on both sides. The overlapping edge film feeding rollers 22 on both sides are not engaged, thus producing products such as... Figure 1b The waterproof membrane shown.

[0057] When the overlapping edge film feeding roller 22 and the stacking roller 23 on one side overlap, and the release film feeding roller 21 on the other side places the release film 3' and the cutting mechanism 6 on the same side cuts it, a product like... can be produced. Figure 6a The waterproof membrane shown.

[0058] When the overlapping edge film feeding rollers 22 on both sides are not working, and only the cutting mechanism 6 on one side is cutting, products like... can be produced. Figure 6b The waterproof membrane shown.

[0059] When the overlapping edge film feeding roller 22 and the stacking roller 23 on one side overlap, and the release film feeding roller 21 on the other side places the release film 3' on it, and neither of the cutting mechanisms 6 on either side cuts, a product like... can be produced. Figure 6c The waterproof membrane shown.

[0060] When neither of the overlapping edge film feeding rollers 22 on both sides is working, and neither of the cutting mechanisms 6 on both sides is cutting, waterproof rolls without any overlapping or cut edges can be produced.

[0061] Example 2

[0062] Another form of the invention is as follows Figure 9 As shown, compared with Embodiment 1, the overlapping edge film feeding rollers 22 and adjacent guide rollers used for pulling the overlapping edge release film 31' on both sides are missing. The entire release film 3' is placed on the release film feeding roller 21, and the film can be produced by the cutting mechanism 6. Figure 1b or Figure 6b The waterproof membrane shown can be produced without any overlapping edges by adjusting the blade of the cutting mechanism 6 backward.

[0063] The production line of this invention can be used to produce flexible sheet materials such as core-shell structure hot-pressed cross-linked polymer base wet-laid rolls or pre-laid on-site composite rolls. This type of waterproof roll uses core-shell structure hot-pressed cross-linked polymer base as reinforcement material, and is made of CPS reactive adhesive that can chemically cross-link and physically bond with cement concrete and an isolation protective layer, which has good anti-water penetration function.

[0064] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
