[0033] Embodiments

[0034] As shown in Figure 1 A specific embodiment of the present application provides an immersion coating system 100 for a waterproofing membrane with a carcass, which includes an immersion coating module 2 and a coating cover module 3, wherein the immersion coating module 2 is used for pre-impregnating the carcass fabric 1 with an immersion coating material; the coating cover module 3 is located on the downstream side of the immersion coating module 2 and includes a coating cover pool 31, a coating cover press roller 32, and a coating cover extrusion device 33, the coating cover pool 31 is filled with a coating cover material, the coating cover press roller 32 is located on the upstream side of the coating cover extrusion device 33 and is used to press the carcass fabric 1 into the coating cover material, and the coating cover extrusion device 33 is located above the coating cover pool 31 and is used to press the coating cover material into the carcass fabric 1.

[0035] The production of the waterproofing membrane with a carcass is made into a roll-shaped material by immersing the carcass fabric 1 into bituminous material. In the present application, the production process of immersing the carcass fabric 1 into bituminous material is divided into two steps of pre-impregnation and coating cover, wherein the pre-impregnation step is completed by the immersion coating module 2, the pre-impregnation step uses the immersion coating material, the coating cover step is completed by the coating cover module 3, the coating cover step uses the coating cover material, and the immersion coating material and the coating cover material both use bituminous material as the main component.

[0036] Specifically, the immersion coating module 2 is located on the upstream side of the coating cover module 3, the carcass fabric 1 is first pre-impregnated by the immersion coating module 2 so that the immersion coating material is infiltrated into the carcass fabric 1, and then the carcass fabric 1 infiltrated with the immersion coating material is adsorbed with the coating cover material in the coating cover pool 31 and then the coating cover material is pressed into the carcass fabric 1 by the coating cover press roller 32 to fill the gap, so that the carcass fabric 1 is not exposed white. In fact, the total consumption of the immersion coating material and the coating cover material for the same carcass fabric 1 does not change much, in other words, the increase in the consumption of the coating cover material corresponds to the decrease in the consumption of the immersion coating material, and the cost of the immersion coating material is higher than that of the coating cover material, so it can be seen that increasing the consumption of the coating cover material and reducing the consumption of the immersion coating material is conducive to reducing the production cost of the waterproofing membrane with a carcass. In the present application, the carcass fabric 1 is extruded by the coating cover extrusion device 33 to make the carcass fabric 1 fully absorb the coating cover material, so as to increase the consumption of the coating cover material, thereby reducing the consumption of the immersion coating material in the pre-impregnation step, and further saving the production cost.

[0037] Furthermore, excess coating material after extrusion is recycled into the coating tank 31, thereby avoiding waste of coating material and further saving production costs.

[0038] In fact, since the impregnation coating only needs to penetrate into the core part of the base fabric in the pre-impregnation step, a semi-impregnation process can be used in the pre-impregnation step, that is, only a small amount of impregnation coating needs to be applied to the lower surface of the base fabric 1.

[0039] like Figure 2 As shown, in some embodiments, the dip coating module 2 includes a dip coating tank 21, a dip coating roller 22, and a dip coating extrusion device 23. The dip coating tank 21 contains a dip coating material, the dip coating roller 22 is used to coat the dip coating material onto the lower surface of the base fabric 1, and the dip coating extrusion device 23 is located downstream of the dip coating roller 22 and is used to extrude the base fabric 1.

[0040] Specifically, the lower part of the roller surface of the dip coating roller 22 is in contact with the dip coating material. During the rotation of the dip coating roller 22, the dip coating material in the dip coating tank 21 is continuously adsorbed onto the roller surface of the dip coating roller 22. The base fabric 1 adsorbs the dip coating material on the roller surface of the dip coating roller 22 as it passes through the dip coating roller 22. The pre-impregnation treatment of the base fabric 1 by the dip coating module 2 adopts a semi-impregnation process, that is, the dip coating material is only coated onto the lower surface of the base fabric 1, and then the dip coating extrusion device 23 presses the dip coating material into the base fabric 1 so that the dip coating material penetrates to the upper surface of the base fabric 1, thereby reducing the consumption of dip coating material and thus saving production costs.

[0041] like Figure 2 As shown, in some embodiments, the dip coating extrusion device 23 includes a plurality of extrusion rollers spaced apart in the vertical direction, with dip coating extrusion sections formed between adjacent extrusion rollers. By providing a plurality of dip coating extrusion sections to extrude the base fabric 1, the dip coating is fully pressed into the base fabric 1, thereby improving the pre-impregnation effect of the base fabric 1 and thus improving the production quality of the reinforced waterproof membrane.

[0042] like Figure 2 As shown, in some embodiments, a first dip coating roller 24 is provided on the upstream side of the dip coating roller 22, and a second dip coating roller 25 is provided on the downstream side of the dip coating roller 22, so as to adjust the tension of the base fabric 1 so that the tension of the base fabric 1 matches the rotation speed of the dip coating roller 22.

[0043] like Figure 3 As shown, in some embodiments, the coating extrusion device 33 includes a fixed roller shaft 331, a movable roller shaft, and a drive mechanism 335. A coating extrusion section 334 for extruding the base fabric 1 is formed between the movable roller shaft and the fixed roller shaft 331. The drive mechanism 335 is drivenly connected to the movable roller shaft to adjust the size of the coating extrusion section 334.

[0044] Specifically, the coating extrusion part 334 is the distance between the roller surface of the movable roller and the roller surface of the fixed roller 331. Since the thickness of the base fabric 1 of the waterproof roll material with a base fabric is different, the size of the coating extrusion part 334 is adjusted by the driving mechanism 335 to adapt to the extrusion of the base fabric 1 with different thicknesses, thereby improving the application range of the dip coating system 100. Moreover, by adjusting the size of the coating extrusion part 334, the extrusion force on the base fabric 1 can also be adjusted to achieve the best effect of the coating material being pressed into the base fabric 1, thereby obtaining a better quality of the waterproof roll material with a base fabric.

[0045] As shown in Figure 3 In some embodiments, the number of movable rollers is two, and each of the two movable rollers forms a coating extrusion part 334 with the fixed roller 331. The base fabric 1 is extruded by the plurality of coating extrusion parts 334 to make the coating material be fully pressed into the base fabric 1, thereby improving the production quality of the waterproof roll material with a base fabric.

[0046] Specifically, one of the movable rollers is a horizontal movable roller 332, and the axis of the horizontal movable roller 332 is in the same horizontal plane as the axis of the fixed roller 331. The other movable roller is a vertical movable roller 333, and the axis of the vertical movable roller 333 is in the same vertical plane as the axis of the fixed roller 331. The horizontal movable roller 332 is provided with a horizontal driving mechanism 335, and the vertical movable roller 333 is provided with a vertical driving mechanism 335.

[0047] Furthermore, the size of the coating extrusion part 334 between the horizontal movable roller 332 and the fixed roller 331 is the horizontal distance between the horizontal movable roller 332 and the fixed roller 331, and the size of the coating extrusion part 334 between the vertical movable roller 333 and the fixed roller 331 is the vertical distance between the vertical movable roller 333 and the fixed roller 331. It can be seen that the adjustment of the size of the coating extrusion part 334 is more convenient and accurate, and it is also beneficial to keep the size of the two coating extrusion parts 334 consistent, thereby avoiding wrinkles caused by the inconsistent extrusion force of the two coating extrusion parts 334 on the base fabric 1, and further improving the production quality of the waterproof roll material with a base fabric.

[0048] As shown in Figure 3 In some embodiments, the fixed roller 331 and the movable roller are both provided with an extrusion protrusion 336. The extrusion protrusion 336 is provided to increase the extrusion force of the coating extrusion part 334 on the base fabric 1, so that the coating material can be better pressed into the base fabric 1, thereby improving the production quality of the waterproof roll material with a base fabric and reducing the consumption of dip coating material.

[0049] Specifically, a plurality of extrusion protrusions 336 are formed on the roller surface of the fixed roller shaft 331, and the plurality of extrusion protrusions 336 are arranged at intervals along the circumferential direction of the fixed roller shaft 331 and extend along the axial direction of the fixed roller shaft 331; a plurality of extrusion protrusions 336 are formed on the roller surface of the movable roller shaft, and the plurality of extrusion protrusions 336 are arranged at intervals along the circumferential direction of the movable roller shaft and extend along the axial direction of the movable roller shaft.

[0050] It should be noted that the length of the extrusion protrusion 336 in the axial direction is at least consistent with the width of the tire base fabric 1 in the axial direction, and the cross section of the extrusion protrusion 336 can be selected from a rectangle, a sector, a combination of a rectangle and a sector, etc., and is preferably a rectangle.

[0051] As shown in the drawings, Figure 3 In some embodiments, the driving mechanism 335 includes a linear guide rail and a stroke-adjustable cylinder, and the end of the movable roller shaft is provided with a bearing seat that is movably connected with the linear guide rail, and the driving end of the stroke-adjustable cylinder is connected with the bearing seat.

[0052] Specifically, the use of the stroke-adjustable cylinder facilitates the accurate adjustment of the size of the coating extrusion part 334, so as to accurately adjust the extrusion force of the coating extrusion part 334 on the tire base fabric 1, thereby facilitating the size of the two coating extrusion parts 334 to remain consistent, and further improving the production quality of the tire waterproof roll.

[0053] In some embodiments, a limiting piece is arranged between the movable roller shaft and the fixed roller shaft 331, and the limiting piece is used to limit the minimum value of the coating extrusion part 334.

[0054] Specifically, the limiting piece is a mechanical limiting member, so as to avoid the coating extrusion part 334 being too small to cause the coating extrusion force to be too large, thereby avoiding the tire base fabric 1 being deformed by extrusion, and further improving the production quality of the tire waterproof roll.

[0055] It should be noted that the limiting piece is made of a hard material, the hard material is covered with a cushioning material, and the shape of the limiting piece is not limited, all of which belong to the protection scope of the present application.

[0056] As shown in the drawings, Figure 3 In some embodiments, the coating extrusion device 33 further includes a floating roller 337 and a potential meter 338, the floating roller 337 is arranged on the downstream side of the movable roller shaft, and the potential meter 338 is used to adjust the position of the floating roller 337 in the up-down direction according to the tension of the tire base fabric 1, so as to match the rotational speed of the movable roller shaft and the fixed roller shaft 331 with the tension of the tire base fabric 1, thereby avoiding the tire base fabric 1 from being folded or wrinkled due to the difference in tension, and further improving the reliability of the dip coating system 100.

[0057] It should be noted that the structure and working principle of the potential meter 338 and the floating roller 337 are well known to those skilled in the art, and do not belong to the core invention points of the present application, and will not be described here.

[0058] As shown in the drawings, in some embodiments, the dipping coating system 100 further comprises a thickness control module 4 arranged at the downstream side of the coating module 3, the thickness control module 4 comprises a coating device 41 and a thickness control extrusion device 42, the coating device 41 is used for coating the coating material on the tire base fabric 1, and the thickness control extrusion device 42 is arranged at the downstream side of the coating device 41 and is used for adjusting the thickness of the coating material on the surface of the tire base fabric 1. Figure 1 Specifically, the coating device 41 comprises a coating roller and a dripping pipeline, the coating roller continuously adsorbs the coating material in the coating pool 31 to the roller shaft surface of the coating roller in the process of rotation, and the lower surface of the tire base fabric 1 adsorbs the coating material on the roller shaft surface of the coating roller at the same time of passing through the coating roller, and the dripping pipeline is used for dripping the coating material to the upper surface of the tire base fabric. The thickness control extrusion device 42 comprises two thickness control extrusion rollers arranged in position, and a thickness control extrusion part is formed between the two thickness control extrusion rollers, the thickness control extrusion part is used for adjusting the thickness of the coating material on the surface of the tire base fabric 1, that is, the tire base fabric 1 after passing through the coating device 41 enters the thickness control extrusion part so that the surface thereof is covered with the coating material of the designed thickness.

[0059] As shown in the drawings, in some embodiments, the dipping coating system 100 further comprises a buffer frame and a deviation rectifying device, the buffer frame is arranged at the upstream side of the deviation rectifying device, the buffer frame is arranged at the downstream side of the dipping coating device, and the deviation rectifying device is arranged at the upstream side of the coating device, and the dipping coating device and the coating device are connected by the buffer frame and the deviation rectifying device.
