Description

Technical Field

[0001] The invention relates to the field of equipment for producing a double tire base, in particular to a double tire base coating device. Background Art

[0002] The existing asphalt waterproofing membrane is generally a single-base waterproofing membrane, that is, it has only one layer of base, and then modified asphalt is coated on the base to complete the production of the modified asphalt waterproofing membrane. However, with the development of society, the needs of existing customers are getting higher and higher. Therefore, in order to meet the performance pursuit of such customers as much as possible, a double-base asphalt waterproofing membrane is designed. The two layers of base are used to complement each other or enhance a certain performance. However, the existing asphalt waterproofing membrane production lines generally produce single-base asphalt waterproofing membranes, which are not suitable for the production of double-base waterproofing membranes. Moreover, there is no production line specifically used for the production of double-base waterproofing membranes in China. Therefore, the existing double-base asphalt waterproofing membrane production lines are generally modified on the basis of single-base asphalt waterproofing membrane production lines, but such production lines were not originally designed for double-base asphalt. The waterproof membrane is designed, so even if the technical transformation is carried out, there will still be many incompatibilities, which will cause the quality of the produced double-base waterproof membrane to be substandard. Take the coating process here as an example. The existing single-base coating is relatively simple, that is, the film is pressed with a roller on the surface of the base after oil soaking. When the bottom film is pressed, it will be cooled simultaneously, and when the top film is pressed, since the bottom film has been cooled, there is no need to cool it again. However, in the case of double-base, the two layers of oil-soaked base are combined, and the thickness is relatively thick. When the bottom film is coated, it is cooled simultaneously in time, and the temperature of the upper surface is still high, which will affect the coating of the top film. If the upper surface of the base is not cooled in advance, it will be easy to scald the top film when coating the top film. Therefore, the existing modified double-base coating device structure is defective, and for this reason, the existing double-base coating device needs to be further modified. Summary of the invention

[0003] The object of the present invention is to provide a double-tire base film laminating device to solve the problem that the top film is easily burned during laminating in the existing double-tire base film mechanism.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A double-film base coating device comprises a bottom film roll supporting mechanism, a bottom film coating roller, a top film roll supporting mechanism and a top film coating roller, wherein the bottom film roll supporting mechanism is arranged below in front of the feeding end of the bottom film coating roller, an upward spray cooling mechanism is arranged below the discharging end of the bottom film coating roller, an air cooling mechanism is arranged above the discharging end of the bottom film coating roller, and the top film roll supporting mechanism is arranged above in front of the feeding end of the top film coating roller.

[0005] An air cooling mechanism is provided above the discharge end of the bottom film laminating roller, which can cool the upper surface of the tire base in advance, so that the top film will not be damaged due to insufficient cooling when laminating the top film.

[0006] As a further preferred embodiment of the present invention, the discharge sides of the bottom film roll support mechanism and the top film roll support mechanism are both provided with edge film smoothing mechanisms, and the edge film smoothing mechanisms include clamping smoothing rollers arranged on both sides of the bottom film and top film conveying paths, and a film passing gap is left between the upper roller and the lower roller of the clamping smoothing rollers.

[0007] After the isolation film roll is almost used up, the edge position of the remaining isolation film roll will be affected by the vertical support rod and the limit head during the rotation, and it is easy to curl up. The edge film smoothing mechanism can straighten the curled edge to make the covered isolation film better.

[0008] As a further preferred embodiment of the present invention, a bottom film tensioning roller is provided between the side film smoothing mechanism and the bottom film laminating roller used in bottom film laminating, and a top film tensioning roller is provided between the side film smoothing mechanism and the top film laminating roller used in top film laminating.

[0009] The bottom film tensioning roller and the top film tensioning roller are provided to tension the bottom film and the top film, so that the isolation film will not be wrinkled after lamination due to insufficient tension.

[0010] As a further preferred embodiment of the present invention, the bottom film tensioning roller and the top film tensioning roller both include a roller body, a rotating shaft, a support plate and a pressure sensor. The rotating shaft is arranged at both ends of the roller body, a rotating shaft support is arranged on the top surface of the support plate, the rotating shaft is rotatably connected to the rotating support, one end of the rotating shaft is connected to a rotating motor, and an electric lifting mechanism is arranged on the bottom surface of the support plate, the electric lifting mechanism is electrically connected to a PLC controller by signal, the pressure sensor is arranged in a rotating shaft connecting hole of the rotating shaft support, and the pressure sensor is electrically connected to the PLC controller by signal.

[0011] The pressure sensor is used to determine whether the tension of the isolation film wrapped around the roller is sufficient. If the tension is too large or insufficient, it will be fed back to the PLC controller. After receiving the signal, the PLC controller controls the electric lifting mechanism to lift the isolation film to adjust the tension.

[0012] As a further preferred embodiment of the present invention, a pre-wetting spray mechanism is further provided between the base film tensioning roller and the base film coating roller, and the spray head of the pre-wetting spray mechanism faces the back side of the base film coating surface.

[0013] Since the temperature of the tire base is relatively high after being immersed in oil, although an upward spray cooling mechanism is set below the discharge end of the base film coating roller for cooling, the base film will be affected by high temperature when it is combined with the base surface of the tire. Therefore, if the base film is not pre-cooled and wetted in advance, it is easy for the base film to be scalded. For this reason, a pre-wetting spray mechanism is set here to wet and cool the base film in advance so that it will not be scalded when it contacts the tire base.

[0014] As a further preferred embodiment of the present invention, a backflow prevention water baffle is further provided above the bottom film tensioning roller, and a front end surface of the backflow prevention water baffle is in contact with the back side of the bottom film coating surface.

[0015] The anti-backflow water baffle can prevent the sprayed cooling water from dripping onto the bottom film tensioning roller, because if the bottom film tensioning roller is wet, the laminating surface of the bottom film will be stained with water, which will affect the laminating effect during lamination.

[0016] As a further preferred embodiment of the present invention, the upward spray cooling mechanism includes evenly arranged bottom film cooling spray pipes, and a water collecting tank is provided below the evenly arranged bottom film cooling spray pipes.

[0017] As a further preferred embodiment of the present invention, a pre-wet cotton brush mechanism is further provided between the top film tensioning roller and the top film coating roller, and the bottom surface of the pre-wet cotton brush mechanism is in contact with the back surface of the top film coating surface.

[0018] If a pre-wetting mechanism is to be set up here to pre-wet the back side of the top film coating surface, the pre-wetting mechanism needs to be set above the top film and the tire base. Therefore, a spray-type structure is no longer possible, because the spray-type structure will inevitably have water droplets falling onto the top surface of the tire base, which will affect the subsequent top film coating operation. Moreover, since the temperature of the tire base has been lowered here, a pre-wetting cotton brush mechanism is selected here, which not only has a pre-wetting effect, but also does not have water droplets.

[0019] As a further preferred embodiment of the present invention, the pre-wetted cotton brush mechanism includes a brush body and a water-immersed cotton brush, the brush body is connected to a cooling water tank through a coolant supply pipe, a water storage cavity is provided in the brush body, the water-immersed cotton brush is arranged on the bottom surface of the brush body, and the bottom surface of the brush body is evenly provided with capillary water-immersing holes connected to the water storage cavity.

[0020] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. An air cooling mechanism is provided above the discharge end of the bottom film laminating roller, which can cool the upper surface of the tire base in advance, so that the top film will not be damaged due to insufficient cooling when laminating the top film.

[0021] 2. After the isolation film roll is almost used up, the edge position of the remaining isolation film roll will be affected by the vertical support rod and the limit head during the rotation process, and it is easy to curl up. The edge film smoothing mechanism can straighten the curled edge to make the covered isolation film better.

[0022] 3. The bottom film tensioning roller and the top film tensioning roller are set to tension the bottom film and the top film, so that the isolation film will not be wrinkled after lamination due to insufficient tension.

[0023] 4. Since the temperature of the tire base is high after being immersed in oil, although an upward spray cooling mechanism is set below the discharge end of the base film coating roller for cooling, the base film will be affected by high temperature when it is combined with the base surface of the tire. Therefore, if the base film is not pre-cooled and wetted in advance, it is easy to get the base film burned. For this reason, a pre-wetting spray mechanism is set here to wet and cool the base film in advance so that it will not be burned when it contacts the tire base.

[0024] 5. The backflow prevention water baffle can prevent the sprayed cooling water from dripping onto the bottom film tensioning roller. If the bottom film tensioning roller is wet, the laminating surface of the bottom film will be stained with water, which will affect the laminating effect.

[0025] 6. If a pre-wetting mechanism is to be set up here to pre-wet the back of the top film coating surface, the pre-wetting mechanism needs to be set above the top film and the tire base. Therefore, a spray-type structure is no longer acceptable, because a spray-type structure will inevitably have water droplets falling onto the top surface of the tire base, which will affect the subsequent top film coating operation. Moreover, since the temperature of the tire base has dropped here, a pre-wetting cotton brush mechanism is selected here, which not only has a pre-wetting effect, but also does not have water droplets.

Specific embodiment 1: Figure 1 , Figure 2 , Figure 3 , Figure 4 A double-film base coating device is shown, comprising a bottom film roll supporting mechanism 1, a bottom film coating roller 2, a top film roll supporting mechanism 3 and a top film coating roller 4, wherein the bottom film roll supporting mechanism 1 is arranged below the bottom film coating roller 2 in front of the feeding end, an upward spray cooling mechanism 5 is arranged below the discharge end of the bottom film coating roller 2, an air cooling mechanism 6 is arranged above the discharge end of the bottom film coating roller 2, and the top film roll supporting mechanism 3 is arranged above the top film coating roller 4 in front of the feeding end.

[0038] An air cooling mechanism is provided above the discharge end of the bottom film laminating roller, which can cool the upper surface of the tire base in advance, so that the top film will not be damaged due to insufficient cooling when laminating the top film. Specific embodiment 2: This embodiment further illustrates the bottom film roll support mechanism 1 and the top film roll support mechanism 3 on the basis of the specific embodiment 1. The discharge sides of the bottom film roll support mechanism 1 and the top film roll support mechanism 3 are provided with a side film smoothing mechanism 7. The side film smoothing mechanism 7 includes clamping smoothing rollers arranged on both sides of the bottom film and top film conveying paths, and a film passing gap is left between the upper roller and the lower roller of the clamping smoothing roller.

[0040] After the isolation film roll is almost used up, the edge position of the remaining isolation film roll will be affected by the vertical support rod and the limit head during the rotation, and it is easy to curl up. The edge film smoothing mechanism can straighten the curled edge to make the covered isolation film better. Specific embodiment 3: This embodiment is based on the specific embodiment 2 and is additionally provided with a bottom film tensioning roller 8 and a film tensioning roller 9. A bottom film tensioning roller 8 is provided between the edge film smoothing mechanism 7 used in bottom film lamination and the bottom film laminating roller 2, and a top film tensioning roller 9 is provided between the edge film smoothing mechanism 7 used in top film lamination and the top film laminating roller 4.

[0042] The bottom film tensioning roller and the top film tensioning roller are provided to tension the bottom film and the top film, so that the isolation film will not be wrinkled after lamination due to insufficient tension. Specific embodiment 4: This embodiment further explains the bottom film tensioning roller 8 and the top film tensioning roller 9 on the basis of the specific embodiment 3. The bottom film tensioning roller 8 and the top film tensioning roller 9 both include a roller body, a rotating shaft, a support plate and a pressure sensor. The rotating shaft is arranged at both ends of the roller body, and a rotating shaft support is arranged on the top surface of the support plate. The rotating shaft is rotatably connected to the rotating support. One end of the rotating shaft is connected to a rotating motor. An electric lifting mechanism is arranged on the bottom surface of the support plate. The electric lifting mechanism is electrically connected to the PLC controller. The pressure sensor is arranged in the rotating shaft connecting hole of the rotating shaft support, and the pressure sensor is electrically connected to the PLC controller.

[0044] The pressure sensor is used to determine whether the tension of the isolation film wrapped around the roller is sufficient. If the tension is too large or insufficient, it will be fed back to the PLC controller. After receiving the signal, the PLC controller controls the electric lifting mechanism to lift the isolation film to adjust the tension. Specific embodiment 5: This embodiment is based on the specific embodiment 2 and a pre-wet spray mechanism 10 is added. A pre-wet spray mechanism 10 is also provided between the base film tensioning roller 8 and the base film coating roller 2. The nozzle of the pre-wet spray mechanism 10 faces the back side of the base film coating surface.

[0046] Since the temperature of the tire base is relatively high after being immersed in oil, although an upward spray cooling mechanism is set below the discharge end of the base film coating roller for cooling, the base film will be affected by high temperature when it is combined with the base surface of the tire. Therefore, if the base film is not pre-cooled and wetted in advance, it is easy for the base film to be scalded. For this reason, a pre-wetting spray mechanism is set here to wet and cool the base film in advance so that it will not be scalded when it contacts the tire base. Specific embodiment 6: This embodiment is based on the specific embodiment 5 and an anti-backflow water baffle is additionally provided. An anti-backflow water baffle 11 is also provided above the bottom film tensioning roller 8, and the front end surface of the anti-backflow water baffle 11 contacts the back side of the bottom film coating surface.

[0048] The anti-backflow water baffle can prevent the sprayed cooling water from dripping onto the bottom film tensioning roller, because if the bottom film tensioning roller is wet, the laminating surface of the bottom film will be stained with water, which will affect the laminating effect during lamination. Specific embodiment 7: This embodiment further illustrates the upward spray cooling mechanism based on the specific embodiment 3. The upward spray cooling mechanism 5 includes evenly arranged bottom film cooling spray pipes, and a water collecting tank is provided below the evenly arranged bottom film cooling spray pipes.

A pre-wet cotton brush mechanism 12 is also provided between the top film tensioning roller 9 and the top film coating roller 4. The bottom surface of the pre-wet cotton brush mechanism 12 is in contact with the back surface of the top film coating surface.

[0051] If a pre-wetting mechanism is to be set up here to pre-wet the back side of the top film coating surface, the pre-wetting mechanism needs to be set above the top film and the tire base. Therefore, a spray-type structure is no longer possible, because the spray-type structure will inevitably have water droplets falling onto the top surface of the tire base, which will affect the subsequent top film coating operation. Moreover, since the temperature of the tire base has been lowered here, a pre-wetting cotton brush mechanism is selected here, which not only has a pre-wetting effect, but also does not have water droplets. Specific embodiment 9: This embodiment further explains the pre-wet cotton brush mechanism 12 on the basis of the specific embodiment 3. The pre-wet cotton brush mechanism 12 includes a brush body and a water-immersed cotton brush. The brush body is connected to the cooling water tank through a coolant supply pipe. A water storage cavity is provided in the brush body. The water-immersed cotton brush is arranged on the bottom surface of the brush body. The bottom surface of the brush body is evenly provided with capillary water-immersing holes connected to the water storage cavity.
