Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane processing technology, and in particular to a coating device for adjustable waterproof membrane size. Background Technology

[0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, landfills, and other locations. It is a flexible building material that can be rolled up to resist leaks of external rainwater and groundwater. As a leak-proof connection between the foundation and the building structure, it serves as the first line of defense in the entire waterproofing project, playing a crucial role. Waterproof membranes require coating during the manufacturing process.

[0003] Existing adjustable waterproof membrane coating devices typically include a coating rack with two horizontally rotatable coating rollers mounted at intervals from top to bottom. Two baffles are positioned opposite each other between the two coating rollers. The waterproof membrane passes between the two baffles, with its sides adhering to the opposite sides of the two baffles. By adjusting the movement of the two baffles, the distance between the two baffles can be adjusted, thereby adapting to waterproof membranes of different widths.

[0004] However, in the above device, the distance between the two coating rollers is fixed, which cannot accommodate roll materials of different thicknesses. If the thickness of the roll material changes, the pressure between the coating rollers may be insufficient or excessive, which may lead to uneven coating or deformation of the roll material. Utility Model Content

[0005] The purpose of this invention is to provide a coating device for adjustable waterproof membrane sizes, which can be adapted to membranes of different thicknesses and widths, and has the effect of uniform coating and effectively ensuring coating quality.

[0007] By adopting the above technical solution, during use, the waterproof membrane is first passed through the gap between the first and second coating rollers. The adjusting component adjusts the size of the gap between the first and second coating rollers according to the required thickness of the waterproof membrane to be coated. Then, the positions of the first baffle, the second baffle, and the telescopic component are adjusted so that the first baffle, the second baffle, and the telescopic component contact the two sides of the waterproof membrane. This allows for adaptive adjustment for membranes of different thicknesses and widths, avoiding situations where the pressure between the coating rollers may be insufficient or excessive, resulting in uneven coating or membrane deformation, and effectively ensuring coating quality.

[0008] A further feature of this invention is that the adjusting assembly includes an adjusting rod rotatably connected to the coating frame in a vertical direction. The adjusting rod is provided with threads of the same pitch but opposite directions. A first slider and a second slider located at the same end of the coating frame are respectively threadedly connected to the adjusting rod. A first motor is fixedly connected to the top of the adjusting rod via a coupling. The first motor is fixedly connected to the coating frame.

[0009] By adopting the above technical solution, the first motor controls the adjustment rod to rotate, so that the first slider and the second slider, which are threadedly connected to the adjustment rod, move synchronously in opposite directions, thereby adjusting the gap between the first oiling roller and the second oiling roller, so that the first oiling roller and the second oiling roller contact the upper and lower surfaces of the waterproof membrane respectively.

[0010] A further feature of this invention is that a vertical guide rod is fixedly connected to the side of the coating frame away from the adjusting rod. The guide rod and the adjusting rod are located at the two ends of the first coating roller and the second coating roller, respectively. The first slider and the second slider near the guide rod are slidably connected to the guide rod, and the guide rod passes through the first slider and the second slider.

[0011] By adopting the above technical solution, the guide rod serves to guide and limit the movement of the first and second oiling rollers up and down, driven by the first and second sliders.

[0012] A further feature of this invention is that a vertical strip groove is provided on the coating frame, and the first slider and the second slider are embedded in the strip groove and are slidably connected to the strip groove.

The sealing strip in the first annular groove is tightly fitted to the side of the first baffle facing the first oiling roller, and the sealing strip in the second annular groove is tightly fitted to the side of the second baffle facing the second oiling roller.

[0017] By adopting the above technical solution, a dynamic seal is maintained between the first baffle and the side of the second baffle closest to the first and second oiling rollers during the adjustment of the width of the first baffle and the second baffle, preventing the paint from leaking from the gap between the roller and the baffle and ensuring uniform coating at the edge of the waterproof membrane.

[0018] A further feature of this invention is that the telescopic member includes an intermediate plate disposed on the same side between a first baffle and a second baffle. Holes for the intermediate plate to be inserted are provided at the bottom of the first baffle and at the top of the second baffle.

A second spring is fixedly connected between the intermediate plate and the second baffle. One end of the second spring is fixedly connected to the second baffle, and the other end is fixedly connected to the intermediate plate.

[0019] By adopting the above technical solution, during the adjustment of the gap between the first and second coating rollers, the distance between the first and second baffles changes accordingly.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

A first coating roller 2 and a second coating roller 3 are horizontally rotatably mounted on the coating frame 1 at intervals from top to bottom. The first and second coating rollers 2 and 3 are symmetrically arranged, with a gap between them for the waterproof membrane to pass through. A rotating shaft 4 is fixedly connected to the center of each of the first and second coating rollers 3. The two ends of the rotating shaft 4 on the first coating roller 2 are rotatably connected to a first slider 5, and the two ends of the rotating shaft 4 on the second coating roller 3 are rotatably connected to a second slider 6. Both the first slider 5 and the second slider 6 are slidably connected to the coating frame 1 in a vertical direction. The coating frame 1 is equipped with an adjustment mechanism to adjust the distance between the first slider 5 and the second slider 6, thereby adjusting the gap size. The component comprises a first coating roller 2 with symmetrically arranged first baffles 8 at both ends, and a second coating roller 3 with symmetrically arranged second baffles 9 at both ends. A telescopic component connects the first baffles 8 and the second baffles 9. In use, the waterproof membrane is first passed through the gap between the first coating roller 2 and the second coating roller 3. The adjustment component adjusts the size of the gap between the first coating roller 2 and the second coating roller 3 according to the required thickness of the waterproof membrane. Then, the positions of the first baffles 8, the second baffles 9, and the telescopic component are adjusted so that the first baffles 8, the second baffles 9, and the telescopic component contact the two sides of the waterproof membrane. This allows for adaptive adjustment for membranes of different thicknesses and widths, avoiding insufficient or excessive pressure between the coating rollers, which could cause uneven coating or membrane deformation, and effectively ensuring coating quality.

[0039] It is important to understand that during coating, an unwinding device and a rewinding device need to be installed on both sides of the coating device. The unwinding device is located on the side closest to the first and second baffles. The waterproof membrane is fed out through the unwinding device, coated with oil by the oiling device, and then rewound by the rewinding device to ensure the smooth progress of the coating work. The unwinding device can use existing unwinding rollers and unwinding motors, and the rewinding device can use existing rewinding rollers and rewinding motors.

[0040] Furthermore, the adjustment assembly includes an adjustment rod 71 rotatably connected to the coating frame 1 in a vertical direction. The adjustment rod 71 is provided with threads of the same pitch but opposite directions. A first slider 5 and a second slider 6 located at the same end of the coating frame 1 are respectively threadedly connected to the adjustment rod 71. A first motor 72 is fixedly connected to the top of the adjustment rod 71 via a coupling. The first motor 72 is fixedly connected to the coating frame 1. A vertical guide rod 73 is fixedly connected to the side of the coating frame 1 away from the adjustment rod 71. The guide rod 73 and the adjustment rod 71 are located at the two ends of the first coating roller 2 and the second coating roller 3, respectively, close to the guide rod 73. The first slider 5 and the second slider 6 of the guide rod 73 are both slidably connected to the guide rod 73. The guide rod 73 is set through the first slider 5 and the second slider 6. The first motor 72 controls the adjustment rod 71 to rotate, so that the first slider 5 and the second slider 6, which are threadedly connected to the adjustment rod 71, move synchronously in opposite directions, thereby realizing the adjustment of the gap between the first oiling roller 2 and the second oiling roller 3, so that the first oiling roller 2 and the second oiling roller 3 contact the upper and lower surfaces of the waterproof membrane respectively. The guide rod 73 guides and limits the up and down movement of the first oiling roller 2 and the second oiling roller 3 driven by the first slider 5 and the second slider 6.

[0041] Furthermore, a vertical strip groove 101 is provided on the coating frame 1. The first slider 5 and the second slider 6 are embedded in the strip groove 101 and are slidably connected to the strip groove 101. The design of the strip groove 101 further provides a limiting and guiding function for the up and down movement of the first slider 5 and the second slider 6.

Sealing strips 10 are embedded in both the first annular grooves 201 and the second annular grooves 31. The first baffle 8 and the second baffle 9 form soft contact with the sealing strips 10, which effectively avoids wear on the first baffle 8, the second baffle 9, the first oiling roller 2 and the second oiling roller 3, and extends their service life.

The sealing strip 10 set in the first annular groove 201 is tightly fitted with the side of the first baffle 8 facing the first coating roller 2, and the sealing strip 10 set in the second annular groove 31 is tightly fitted with the side of the second baffle 9 facing the second coating roller 3. During the adjustment of the width of the first baffle 8 and the second baffle 9, a dynamic seal is always maintained with the side of the first baffle 8 and the second baffle 9 closest to the first coating roller 2 and the second coating roller 3, to prevent the paint from leaking from the gap between the roller and the baffle and to ensure uniform coating at the edge of the waterproof membrane.

[0044] Furthermore, the telescopic component includes an intermediate plate 11 disposed between a first baffle 8 and a second baffle 9 on the same side.

The design of the intermediate plate 11 ensures that the intermediate plate 11 is always in contact with both sides of the waterproof membrane, preventing the waterproof membrane from deviating during coating.

[0045] Furthermore, first cylinders 14 are symmetrically arranged on both sides of the coating frame 1.

[0046] Furthermore, each of the two first sliders 5 is fixedly connected to a first fixing plate 15 at one of its opposing ends. A first oil tank 17 is fixedly installed between the tops of the two first fixing plates 15.

Each of the two second sliders 6 is fixedly connected to a second fixing plate 16 at one of its opposing ends. A second oil tank 18 is fixedly installed between the bottoms of the two second fixing plates 16. The top of the second oil tank 18 is open, and a second oiling sponge 20 is placed inside the second oil tank 18. The top of the second oiling sponge 20 contacts the second oiling roller 3.

The end of the fourth spring 24 away from the second limiting plate 23 is fixedly connected to the second oil tank 18. Under the action of the third spring 22, the first limiting plate 21 controls the first oiling sponge 19 to always be in contact with the first oiling roller 2. Under the action of the fourth spring 24, the second limiting plate 23 controls the second oiling sponge 20 to always be in contact with the second oiling roller 3.
