Waterproof and drainage integrated board forming machine, waterproof and drainage integrated board and its forming process

Abstract

The present invention discloses a waterproof and drainage integrated board, a forming machine and a forming process. A first concave roller, a convex roller, a second concave roller and a mirror roller are arranged on a frame. The convex roller rolls relatively with the first concave roller and the second concave roller respectively, and the mirror roller rolls relatively with the second concave roller. The drainage layer substrate of the present invention is extruded from a first extrusion head. After being shaped, it immediately follows the second concave roller to rotate to the bottom and is directly fused with the waterproof layer just extruded and formed by the second extrusion head. By adjusting the gap between the second concave roller and the mirror roller to apply a certain pressure for pressing and calendering, the drainage layer and the waterproof layer are combined into one. The hollow convex platform has good strength, and the opening on its bottom surface is sealed by the waterproof layer. Even if the convex platform cracks and leaks, there is still the waterproof layer to prevent leakage; the substrate and the fused waterproof layer have a double-layer thickness, which further increases its strength and waterproof property.

Description

Technical Field

[0001] The present invention relates to the technical field of building engineering component forming equipment, in particular to a waterproof and drainage integrated board forming machine, a waterproof and drainage integrated board and its forming process. Background Art

[0002] Drainage projects are widely used in building engineering, traffic engineering, garden engineering, municipal engineering, etc. Among them, plastic drainage boards are widely used. A plastic drainage board is made by thermoforming a convex platform on a plastic substrate, and the space between adjacent convex platforms forms a drainage channel. It is laid on the ground, soil or rock formation and other base surfaces to prevent water infiltration. The Chinese invention patent 2011103758741 of the present inventor discloses a drainage board forming machine, and the formed drainage board is a common single-layer structure. However, due to the forming thickness of the drainage board (for example, the thickness is relatively thin to save materials), the material (for example, using a mixed material to reduce costs), the working environment (for example, being used in sandstone areas is easy to cut the plastic layer), and plastic aging and other influences, it will crack, especially easily in the convex platform part, because the convex platform part protrudes outwards and needs to bear the force, so it is more vulnerable to damage; once damaged, water seepage and leakage will occur, and leakage points will appear. During actual construction, an asphalt waterproof layer also needs to be laid on the surface of the soil and other bases to achieve the waterproof effect.

[0003] Chinese utility model patent 2019213530377 - a self-adhesive waterproof layer integrated drainage board attempts to melt the asphalt waterproof coil at the bottom of the drainage board to form an integral body, and then use a blowtorch burner to heat-melt the waterproof coil at the bottom of the drainage board during laying. The temperature during heat-melting should be controlled so that the surface of the waterproof coil melts but does not flow. Then, it is rolled forward while heat-melting. This method is actually just a simple combination of the drainage board and the asphalt layer, but the workload is still huge during construction, and it is difficult to control the burning effect of the blowtorch. At the same time, the convex platforms on the drainage board will also soften and deform and lose their bearing capacity, and even burn through the drainage board in severe cases. Therefore, it still has certain defects. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the existing drainage board forming, the applicant of the present invention provides a waterproof and drainage integrated board forming machine, a waterproof and drainage integrated board and its forming process with reasonable structures, which have good drainage and waterproof effects at the same time, and reduce the production line input cost and inventory cost.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A waterproof and drainage integrated board forming machine, in which a first concave roller, a convex roller, a second concave roller and a mirror roller are arranged on a frame, the convex roller rolls relatively with the first concave roller and the second concave roller respectively, and the mirror roller rolls relatively with the second concave roller;

[0007] A number of first concave cavities are formed on the roll surface of the first concave roll, a number of second concave cavities are formed on the roll surface of the second concave roll, a number of convex grains are correspondingly arranged on the roll surface of the convex roll, and the convex grains are respectively in corresponding cooperation with the first concave cavities and the second concave cavities; the roll surface of the mirror roll is a smooth surface.

[0008] As a further improvement of the above technical solution:

[0009] The meeting point of the convex roll and the first concave roll is located on one side of the first extrusion head; the convex roll, the second concave roll and the mirror roll are arranged in sequence, and the meeting point of the second concave roll and the mirror roll is located on one side of the second extrusion head.

[0010] The central connection line of the convex roll and the first concave roll is orthogonally arranged with the central connection line of the convex roll, the second concave roll and the mirror roll, and the convex roll, the second concave roll and the mirror roll are arranged side by side up and down.

[0011] The central axes of the first concave roll, the convex roll, the second concave roll and the mirror roll are in the same horizontal plane; or the central axes of the second concave roll and the mirror roll are in the same horizontal plane, and the included angle β between the central connection line of the first concave roll and the convex roll and the central connection line of the second concave roll and the mirror roll is greater than 90° and less than 180°.

[0012] The central angle α of the wrapping arc of the upper substrate on the convex roll is greater than or equal to 180°, and the arc length of the wrapping arc is greater than or equal to πr.

[0013] The second extrusion head is facing the meeting point of the second concave roll and the mirror roll; or the second extrusion head is offset horizontally by a distance d from the meeting point towards the mirror roll.

[0014] A heating structure is arranged inside the second concave roll or the mirror roll, and the heating temperature range is 30 - 80°C.

[0015] A hot air gun is arranged outside the second concave roll and heats the bottom surface of the substrate, and the heating temperature range is 200 - 400°C.

[0016] A film winding roll for a hot melt adhesive film is arranged outside the meeting point of the second concave roll and the mirror roll.

[0017] A heating plate is arranged outside the second concave roll at a certain distance from the second concave roll. During operation, the heating area partially covers the drainage layer wound during operation; the heating plate is arc-shaped and is arranged on the upper half side of the second concave roll close to the convex roll.

[0018] Sliders are respectively provided on the supports at both ends of the first concave roller, convex roller and mirror roller, and slide rails are correspondingly arranged on the frame. The sliders are slidably arranged on the second slide rail. The first concave roller, convex roller and mirror roller can be driven by a linear drive mechanism to slide, so as to adjust the gap between the two rollers. The apertures of the first concave cavity and the second concave cavity are equivalent and both are larger than the outer diameter of the convex particles. The radial distance between the outer surface of the convex particles and the inner surface of the first concave cavity / second concave cavity is equivalent to or larger than the thickness of the substrate. The gap between the mirror roller and the second concave roller is smaller than the sum of the thicknesses of the substrate and the waterproof layer.

[0019] The first concave roller is connected to the motor through a transmission mechanism. The first concave roller, convex roller, second concave roller and mirror roller respectively transmit torque through gear meshing. A guide roller is arranged on the frame, and the guide roller is connected to the motor through a transmission mechanism.

[0020] A number of rollers are arranged on the opposite sides at the bottom of the frame. The rollers are connected to the motor through a transmission mechanism, and the outer circumference of the rollers has teeth. Corresponding tracks are arranged on the ground of the workshop, and a number of rolling teeth are opened on the tracks. The teeth of the rollers are engaged with the rolling teeth of the tracks.

[0021] A forming process of the waterproof and drainage integrated board using the above-mentioned waterproof and drainage integrated board forming machine includes the following steps:

[0022] I. The first extruder extrudes and forms a flat substrate.

[0023] II. The substrate enters between the first concave roller and the convex roller to form a hollow boss.

[0024] III. The substrate and the boss form a drainage layer and are transferred from the convex roller to the second concave roller.

[0025] IV. The second extruder extrudes and forms a flat waterproof layer. The waterproof layer and the drainage layer enter between the second concave roller and the mirror roller together. The bottom surface of the substrate of the waterproof layer and the drainage layer is fused under a certain pressure to form a waterproof and drainage integrated board.

[0026] As a further improvement of the above technical solution:

[0027] The bottom surface of the substrate is heated before the waterproof layer is fused with the bottom surface of the substrate.

[0028] A waterproof and drainage integrated board produced by using the above-mentioned waterproof and drainage integrated board forming machine. The drainage layer includes a substrate and a hollow boss. The waterproof layer is fused with the bottom surface of the substrate to seal the bottom opening of the boss. The drainage layer and the waterproof layer are integrally fused during extrusion molding.

[0029] As a further improvement of the above technical solution:

[0030] The boss has a "crater"-shaped pressing part with a high periphery and a low middle. Between the bosses is a fusion flat layer of the drainage layer and the waterproof layer.

[0031] The maximum thickness T of the pressing-in part max is greater than the thickness t of the fusion flat plate layer.

[0032] The minimum thickness T of the pressing-in part min is greater than or equal to the thickness t2 of the waterproof layer.

[0033] The average thickness T of the pressing-in part is greater than the thickness t of the fusion flat plate layer.

[0034] A hot melt adhesive layer is bonded between the drainage layer and the waterproof layer.

[0035] The beneficial effects of the present invention are as follows:

[0036] The drainage layer substrate of the present invention is extruded from the first extrusion head, vacuum-adsorbed and formed into a boss, cooled and shaped, and then immediately follows the second concave roller to rotate to the bottom, and directly fuses with the waterproof layer just extruded and formed by the second extrusion head. At this time, both the substrate and the waterproof layer are in a softened state at a relatively high temperature, and the two are smoothly fused. Moreover, by adjusting the gap between the second concave roller and the mirror roller to apply a certain pressure for pressing and calendering, the drainage layer and the waterproof layer are combined into one. The hollow boss not only has good strength, but also the opening on its bottom surface is sealed by the waterproof layer. Even if the boss cracks and leaks, the waterproof layer can still prevent leakage; the substrate and the fused waterproof layer have a double-layer thickness, which further increases their strength and waterproofness. The waterproof and drainage integrated board of the present invention can directly be laid on the base surface during construction without laying an asphalt layer or waterproof coiled material anymore, because the waterproof layer can fully ensure the same waterproof effect as the asphalt layer.

[0037] Before the substrate of the present invention is welded to the waterproof layer, it experiences a certain cooling time while rotating with the second concave roller. The heating plate only heats the bottom surface of the substrate, and at the same time, the boss of the substrate remains in the second concave cavity and gradually cools. That is, during this period, both the heating and heat preservation of the bottom surface of the substrate and the cooling of the boss are taken into account. It not only ensures that the bottom surface smoothly fuses with the waterproof layer while maintaining a relatively high temperature level, but also allows the boss to have time and space to cool, avoiding deformation of the boss and ensuring the forming stability and strength of the boss.

[0038] The waterproof layer of the present invention is directly extruded and formed and then fused, without the need for separate production and winding. This saves the production, winding and other equipment required for separate production, saves equipment costs, also saves production line space, reduces the space requirements for the production workshop, and thus reduces the input cost of the production line; moreover, the waterproof layer does not need to be wound and reserved for use anymore, nor does it need to reserve the corresponding inventory space, reducing the inventory cost.

[0039] The first concave roller, convex roller, and mirror roller of the present invention adjust the radial distance through the sliding movement of the support, so as to match with substrates and waterproof layers of different thicknesses, and are flexibly applicable to drainage plates of various specifications, with a wide range of applications; by adjusting the radial distance, the pressing force between the substrate and the waterproof layer can also be adjusted, improving the firmness of fusion and the reliability of the drainage plate. The adjustable base also makes the distance between the molding machine and the extrusion machine adjustable, ensuring the production quality of the product and facilitating the maintenance of the equipment.

Detailed implementation manners

[0054] The following combines with the attached drawings to illustrate the detailed implementation manners of the present invention.

[0055] First embodiment:

[0056] As Figure 1 , Figure 3 , Figure 4 , Figure 8As shown in the figure, the frame 1 of the present invention has vertical support plates on opposite sides. Horizontally arranged between the two support plates are a first concave roller 2, a convex roller 3, a second concave roller 4 and a mirror roller 5 (also known as a light roller), which are parallel to each other. The first concave roller 2 is located behind the convex roller 3, and their central axes are on the same horizontal plane; the second concave roller 4 and the mirror roller 5 are arranged vertically below the convex roller 3 in sequence from top to bottom, and the central axes of the three are on the same vertical plane; the central connection line between the convex roller 3 and the first concave roller 2 is orthogonal to the central connection line between the convex roller 3, the second concave roller 4 and the mirror roller 5. A number of first concave cavities 21 are arrayed on the circumferential surface of the first concave roller 2, a number of second concave cavities 41 are arrayed on the circumferential surface of the second concave roller 4, and a number of convex grains 31 are correspondingly arrayed on the circumferential surface of the convex roller 3. The convex grains 31 cooperate with the first concave cavities 21 and the second concave cavities 41 respectively; the radial distance between the top surface of the convex grain 31 and the bottom surface of the first concave cavity 21 / second concave cavity 41 is equivalent to or greater than the thickness of the substrate 100, ensuring that the height of the boss 101 punched out by the convex grain 31 on the substrate 100 meets the requirements; the apertures of the first concave cavity 21 and the second concave cavity 41 are equivalent and both are larger than the outer diameter of the convex grain 31. The radial distance between the outer surface of the convex grain 31 and the inner surface of the first concave cavity 21 / second concave cavity 41 matches or is greater than the thickness of the substrate 100, ensuring that while the substrate 100 is smoothly pressed into the first concave cavity 21 / second concave cavity 41 by the convex grain 31, it has a small pressing resistance, which is more conducive to the formation of the boss 101. The circumferential surface of the mirror roller 5 is a smooth surface, and the gap between the mirror roller 5 and the second concave roller 4 is less than the sum of the thicknesses of the substrate 100 and the waterproof layer 200, ensuring that the substrate 100 and the waterproof layer 200 are smoothly compounded into one body.

[0057] As Figure 1 shown, the first concave roller 2 is connected to the motor through a transmission mechanism. A driving wheel 10 is sleeved on the first concave roller 2, a first-stage driven wheel 11 is sleeved on the convex roller 3, a second-stage driven wheel 12 is sleeved on the second concave roller 4, and a third-stage driven wheel 13 is sleeved on the mirror roller 5. The driving wheel 10, the first-stage driven wheel 11, the second-stage driven wheel 12 and the third-stage driven wheel 13 are all gears, and torque is transmitted through gear cooperation respectively; during operation, the motor drives the first concave roller 2 to rotate through the transmission mechanism, and drives the convex roller 3, the second concave roller 4 and the mirror roller 5 to rotate in sequence through gear transmission. As Figure 4 shown, relative rolling occurs respectively between the first concave roller 2 and the convex roller 3, between the convex roller 3 and the second concave roller 4, and between the second concave roller 4 and the mirror roller 5.

[0058] As Figures 4 to 7As shown, the first extrusion head 24 of the first extruder (not the structure of this patent) is arranged above the meeting point of the first concave roller 2 and the convex roller 3. The first extruder extrudes the substrate 100 through the first extrusion head 24. The substrate 100 continuously enters the mating part of the two from the meeting point of the first concave roller 2 and the convex roller 3. The convex grains 31 on the convex roller 3 press the corresponding part of the substrate 100 into the first concave cavity 21 of the first concave roller 2. At the same time, the vacuum adsorption mechanism on the convex roller 3 is used for thermoforming, so as to form a number of hollow bosses 101 with open bottoms arranged in an array on the substrate 100. At this time, a drainage plate structure including the substrate 100 and the bosses 101 integrated is formed, which is defined as the drainage layer in this patent. The convex roller 3 drives the formed drainage layer to rotate to the mating part with the second concave roller 4. When the convex grains 31 cooperate with the second concave cavity 41, the bosses 101 of the drainage layer are transferred into the second concave cavity 41, and the bosses 101 are kept sunk in the second concave cavity 41 and rotate with the second concave roller 4 to the meeting part with the mirror roller 5. The rotation process of the second concave roller 4 gives the bosses 101 a certain cooling time, which is beneficial to improving the forming stability and strength of the bosses 101 and avoiding deformation of the bosses 101. The second extrusion head 25 of the second extruder (not the structure of this patent) is arranged on one side of the meeting point of the second concave roller 4 and the mirror roller 5. The second extruder extrudes the waterproof layer 200 through the second extrusion head 25. The waterproof layer 200 continuously enters the meeting part from the meeting point of the second concave roller 4 and the mirror roller 5, and is melted and compounded with the bottom surface of the substrate 100 of the drainage layer brought down by the second concave roller 4 into one body. An arc-shaped heating plate 7 is arranged around the outside of the second concave roller 4 on the side with the drainage layer and at a certain distance from the second concave roller 4. The heating plate 7 is arranged on the upper half side of the second concave roller 4 close to the convex roller 3. The heating area of the heating plate 7 partially covers the drainage layer wound during work. The heating plate 7 keeps warm or heats the bottom surface of the substrate 100 of the drainage layer, which is beneficial to the smooth fusion of the substrate 100 and the waterproof layer 200. At this time, the bosses 101 of the drainage layer are retained in the second concave cavity 41, and the second concave cavity 41 plays a role in protecting the bosses 101, avoiding further temperature rise of the bosses 101 due to the heating effect of the heating plate 7, being beneficial to improving the forming stability of the bosses 101 of the drainage layer and avoiding deformation of the bosses 101.

[0059] As Figure 1 , Figure 8As shown in the figure, both ends of the first concave roller 2 are provided with first supports 14. The first supports 14 are connected to the motor. A first slider 15 is fixed to the bottom surface of the first supports 14. A first slide rail 16 is correspondingly arranged on the frame 1. The first slider 15 is slidably arranged on the first slide rail 16. The first supports 14 can be driven by the motor to slide back and forth along the first slide rail 16 to radially adjust the radial distance between the first concave roller 2 and the convex roller 3. Both ends of the convex roller 3 are provided with second supports 17. The second supports 17 are connected to the motor. A second slider 18 is fixed to the side surface of the second supports 17. A second slide rail 19 is correspondingly arranged on the frame 1. The second slider 18 is slidably arranged on the second slide rail 19. The second supports 17 can be driven by the motor to slide up and down along the second slide rail 19 to radially adjust the radial distance between the convex roller 3 and the second concave roller 4. Both ends of the mirror roller 5 are provided with third supports 20. The third supports 20 are connected to the motor. A third slider 26 is fixed to the side surface of the third supports 20. A third slide rail 22 is correspondingly arranged on the frame 1. The third slider 26 is slidably arranged on the third slide rail 22. The third supports 20 can be driven by the motor to slide up and down along the third slide rail 22 to radially adjust the radial distance between the mirror roller 5 and the second concave roller 4. Both ends of the second concave roller 4 are provided with fourth supports 23. The fourth supports 23 are fixed to the frame 1 through fasteners. In this embodiment, the first concave roller 2, the convex roller 3, and the mirror roller 5 adjust the radial distance through the sliding movement of the supports, so as to be matched with the substrates 100 and waterproof layers 200 of different thicknesses, and are flexibly applicable to drainage plates of various specifications, with a wide range of applications; by adjusting the radial distance, the pressing force between the substrate 100 and the waterproof layer 200 can also be adjusted, the firmness of fusion can be improved, and the reliability of the drainage plate can be improved. In other embodiments, the first concave roller 2, the convex roller 3, and the mirror roller 5 can also be driven by other linear drive mechanisms to achieve sliding and realize the adjustment of the radial distance.

[0060] As Figure 4 shown, a guide roller 6 is arranged on the frame 1, below and behind the mirror roller 5. The guide roller 6 is connected to the motor through a transmission mechanism; during operation, the motor drives the guide roller 6 to rotate through the transmission mechanism, and conveys the composite waterproof and drainage plate to the next process section.

[0061] As Figure 1 , Figure 2 shown, two tracks 8 are arranged in parallel on the ground of the workshop along the conveying direction of the drainage plate. A plurality of rolling teeth 81 are evenly arranged on the upper surface of the tracks 8; a plurality of rollers 9 are correspondingly arranged on the opposite sides at the bottom of the frame 1 corresponding to the tracks 8. The outer circumference of the rollers 9 has teeth 91. The teeth 91 of the rollers 9 cooperate with the rolling teeth 81 of the tracks 8; the rollers 9 are connected to the motor through a transmission mechanism. The motor can drive the rollers 9 to rotate through the transmission mechanism to realize walking on the tracks 8 and adjust the position of the equipment.

[0062] In actual use of the present invention, the substrate 100 is extruded from the first extrusion head 24. After being formed into a drainage layer by vacuum forming with the first concave roller 2 and the convex roller 3, it follows the convex roller 3 to rotate to the mating part with the second concave roller 4, and winds around the second concave roller 4 when the convex roller 3 and the second concave roller 4 are in cooperation, and then rotates with the second concave roller 4 to the confluence part of the second concave roller 4 and the mirror roller 5; the waterproof layer 200 is extruded from the second extrusion head 25 and fused with the drainage layer at the confluence part of the second concave roller 4 and the mirror roller 5; the drainage board formed by fusion and compounding into one body is conveyed to the next process section through the guide roller 6.

[0063] Second embodiment:

[0064] As Figure 9 shown, in this embodiment, the first concave roller 2, the convex roller 3, the second concave roller 4 and the mirror roller 5 are horizontally arranged side by side, the central axes of the four rollers are on the same horizontal plane, and the confluence points between every two of the four rollers are also on the same horizontal plane.

[0065] The first extrusion head 24 is vertically arranged directly above the confluence of the first concave roller 2 and the convex roller 3 and extrudes the substrate 100 vertically downward towards the confluence of the first concave roller 2 and the convex roller 3; the substrate 100 enters the entry point 102 of the confluence of the first concave roller 2 and the convex roller 3, and a number of hollow bosses 101 with open bottoms are formed in an array arrangement on the substrate 100; the arc section between the entry point 102 and the exit point 103 where it exits the confluence of the convex roller 3 and the second concave roller 4 is the wrapping arc 104 wrapped around the convex roller 3. At this time, the central angle α of the wrapping arc 104 is 180°, and the arc length L of the wrapping arc 104 is πr (r is the radius of the convex roller 3, and the arc length L is equal to the semi-circular arc length of the convex roller 3). Compared with the first embodiment, the central angle of the wrapping arc 104 in this embodiment is larger, the arc length is longer, the travel distance of the substrate 100 on the convex roller 3 after forming is longer, and the residence time is longer. That is, the substrate 100 obtains a longer shaping travel and time on the convex roller 3, which is more conducive to the shaping of the hollow bosses 101 on the substrate 100, reduces the shrinkage rate of the substrate 100 after leaving the convex roller 3, and improves the forming stability and strength of the substrate 100.

[0066] The second extrusion head 25 is vertically arranged directly above the confluence of the second concave roller 4 and the mirror roller 5 and extrudes the waterproof layer 200 vertically downward towards the confluence of the second concave roller 4 and the mirror roller 5; the second concave roller 4 and the mirror roller 5 are horizontally arranged, which is conducive to the vertical casting of the waterproof layer 200. The vertical casting of the waterproof layer 200 is more conducive to the intersection and hot melt compounding with the substrate 100, and can improve the flatness after compounding. The second extrusion head 25 is directly opposite to the confluence of the second concave roller 4 and the mirror roller 5, which can make the waterproof layer 200 vertically enter the confluence, which is more conducive to the compounding of the substrate 100 and the waterproof layer 200 and improves the bonding strength between the substrate 100 and the waterproof layer 200.

[0067] In this embodiment, heating structures are respectively arranged inside the second concave roller 4 and the mirror roller 5 to heat the roller surfaces of the second concave roller 4 and the mirror roller 5, and the heating temperature range of the roller surfaces is controlled at 30 - 80°C. Heating the roller surface of the second concave roller 4 can prevent the bosses 101 of the substrate 100 from shrinking and staying in the second concave cavity 41, thus avoiding the phenomenon of internal jamming. Heating the roller surface of the mirror roller 5 is beneficial to the intersection and hot melt compounding of the waterproof layer 200 with the substrate 100 after extrusion, improving the bonding strength after compounding and achieving a better compounding effect.

[0068] To improve the compounding effect and enable better fusion of the substrate 100 and the waterproof layer 200, in this embodiment, a hot air gun 27 is arranged outside the second concave roller 4 to heat the bottom surface of the substrate 100. The heating temperature range is controlled at 200 - 400°C. The temperature of the hot air gun 27 is determined according to the linear velocity of the substrate 100. When the linear velocity is slow, the temperature of the hot air gun 27 is lower; when the linear velocity is fast, the temperature of the hot air gun 27 is higher. The wind speed of the hot air gun 27 is also controllable, and the air volume is adjusted by frequency conversion.

[0069] For the relatively thin substrate 100 and the waterproof layer 200, in order to further improve the peel strength between the two, in this embodiment, a film winding roller 28 can also be arranged outside the confluence of the second concave roller 4 and the mirror roller 5 for placing a hot melt adhesive film roll. The hot melt adhesive film roll feeds the hot melt adhesive film 300 to the confluence of the second concave roller 4 and the mirror roller 5, between the substrate 100 and the waterproof layer 200, and is bonded between the substrate 100 and the waterproof layer 200 after hot melting to improve the bonding strength.

[0070] Third Embodiment:

[0071] As Figure 10 shown, different from the second embodiment, in this embodiment, the second concave roller 4 and the mirror roller 5 are horizontally arranged, and the first concave roller 2 and the convex roller 3 are arranged with a certain upward inclination angle, that is, the included angle β between the center connection line of the first concave roller 2 and the convex roller 3 and the center connection line of the second concave roller 4 and the mirror roller 5 is greater than 90° and less than 180°. At this time, the central angle α of the wrapping arc 104 of the substrate 100 on the convex roller 3 is greater than 180° and less than 270°, and the arc length L is greater than πr and less than 1.5πr. The central angle of the wrapping arc 104 is further increased, and the arc length is further lengthened, which is more conducive to the hollow bosses 101 on the substrate 100 staying on the convex grains 31 of the convex roller 3 for as long as possible, avoiding shrinkage after premature detachment, and being beneficial to improving the forming stability and strength of the substrate 100.

[0072] In this embodiment, the second extrusion head 25 is offset horizontally by a distance d towards the mirror roller 5 at the confluence of the second concave roller 4 and the mirror roller 5. The range of d is 50 - 200 mm. The second extrusion head 25 is offset towards the mirror roller 5. The waterproof layer 200 extruded therefrom first flows onto the surface of the mirror roller 5 and crystallizes, and then follows the rotation of the mirror roller 5 into the confluence for lamination. The waterproof layer 200 obtains a certain crystallization time on the mirror roller 5 and is thermally laminated with the substrate 100 after preliminary crystallization, resulting in higher flatness.

[0073] First embodiment of the waterproof and drainage integrated board:

[0074] As Figure 11 , Figure 12 shown, the waterproof and drainage integrated formed board formed by the above equipment includes a drainage layer with a substrate 100 and a boss 101, and the waterproof layer 200 is integrally fused. The top surface of the waterproof layer 200 is fused with the bottom surface of the substrate 100 and closes the bottom opening of the boss 101. After the substrate 100 and the waterproof layer 200 are fused, a fused flat plate layer 400 is formed between the bosses 101. The thickness t of the fused flat plate layer 400 is the sum of the thickness t1 of the substrate 100 and the thickness t2 of the waterproof layer 200. Since the boss 101 is hollow and has an opening at the bottom, and there is an extrusion pressure between the two rollers when the substrate 100 and the waterproof layer 200 are laminated, under the action of the extrusion pressure, the surface layer of the waterproof layer 200 in a high-temperature and softened state is pressed into the boss 101, and a pressed-in part 201 is formed at the mouth of the boss 101 after cooling. The pressed-in part 201 is uneven and has a "crater" shape with a high periphery and a low middle. As Figure 12 shown, each part of the formed waterproof and drainage integrated formed board is sectioned, and then a caliper is used to measure the thickness t of the fused flat plate layer 400, the thickness t1 of the substrate 100, and the thickness T n of multiple points (five points are taken in this embodiment) randomly selected on the pressed-in part 201. n The detection is carried out respectively. According to the detection data, the thickness t2 of the waterproof layer 200 and the average thickness T of the pressed-in part 201 are calculated. In this embodiment, a waterproof and drainage integrated board sample is detected, and the detection data is: the thickness t of the fused flat plate layer 400 = 2.2 mm, the thickness t1 of the substrate 100 is t1 = 1.0 mm, and the thickness T max of the five points of the pressed-in part 201 are 3.6 mm, 4.2 mm, 2.5 mm, 3.0 mm, and 4.4 mm respectively. By calculation, the thickness t2 of the waterproof layer 200 = 2.2 - 1.0 = 1.2 mm, and the average thickness T of the pressed-in part 201 = (3.6 + 4.2 + 2.5 + 3.0 + 4.4) / 5 = 3.54 mm. It can be seen from the detected and calculated data that the maximum thickness T max of the pressed-in part 201 is greater than the thickness t of the fused flat plate layer 400, and the minimum thickness T minGreater than or equal to the thickness t2 of the waterproof layer 200, the average thickness T of the pressed-in part 201 is greater than the thickness t2 of the waterproof layer 200. When the inner diameter of the boss 101 is small, after the pressed-in part 201 is pressed into the boss 101, it is squeezed and piled up higher, and the average thickness T of the pressed-in part 201 is even greater than the thickness t of the fusion flat plate layer 400. The pressed-in part 201 bulges into the boss 101 of the waterproof layer 200, not only closing the bottom surface of the boss 101, which is beneficial to improving the service life and reliability of the waterproof board, but also when the pressed-in part 201 is pressed into the boss 101, the outer side surface of the pressed-in part 201 is attached to the inner side surface of the boss 101, forming an effective support for the boss 101 at the opening corner, which can improve the support strength of the boss 101, reinforce the boss 101, prevent the boss 101 from deforming, and is more conducive to improving the compressive performance, service life and reliability of the waterproof board.

[0075] Second embodiment of the waterproof and drainage integrated board:

[0076] As Figure 13 shown, for the waterproof and drainage integrated forming board formed by the equipment that adds the hot melt adhesive layer film, a layer of hot melt adhesive film 300 is also bonded between the drainage layer and the waterproof layer 200, which improves the peeling strength of the forming board and also improves the service life and reliability of the waterproof board.

[0077] The above description is an explanation of the present invention, not a limitation of the present invention. Without departing from the spirit of the present invention, the present invention can be modified in any form. For example, slightly adjusting the arrangement positions and angles of the four rollers, or arranging the present invention horizontally, etc., as long as the purpose of integrating the waterproof layer and the drainage layer into one body can be achieved.
