Description

Technical Field

[0001] The utility model relates to the technical field of pre-laid waterproof coiled material production, and particularly relates to a pre-laid waterproof coiled material production device. Background Art

[0002] The structure of the traditional pre-laid waterproof coiled material is usually that a hot melt adhesive is coated and a sintered sand layer is pasted on one side of the HDPE base material layer from inside to outside in sequence. Now, in order to meet the standards, a hot melt adhesive needs to be coated and an isolation film layer needs to be pasted on the other side of the HDPE base material layer from inside to outside in sequence.

[0003] In the existing production method of pre-laid waterproof coiled materials, two processing devices are required to process the two sides of the HDPE base material layer. That is, the staff first installs the HDPE base material roll to be processed on the unwinding roller of the first processing device. After the processing is completed, the staff removes the HDPE base material roll with one side processed and installs it on the unwinding roller of the second processing device, so that the second processing device processes the other side of the HDPE base material layer. In the process of processing the HDPE base material layer, the method of requiring the staff to disassemble and install the HDPE base material roll midway increases the labor intensity of the staff and reduces the processing efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to design a pre-laid waterproof coiled material production device, which can solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

Along the conveying direction of the HDPE base material layer, an unwinding roller, a first glue coating mechanism, a first cooling mechanism, a sintered sand layer roller, a second glue coating mechanism, a second cooling mechanism, an isolation film layer roller and a winding roller are sequentially installed on the frame. The first glue coating mechanism is used to coat the hot melt adhesive on one side of the HDPE base material layer, and the second glue coating mechanism is used to coat the hot melt adhesive on the other side of the HDPE base material layer.

[0007] Further, the frame includes a bottom plate, a support plate and a top plate. The top plate is directly above the bottom plate.

The nozzle of the glue spraying machine is aligned with the coating roller, and the HDPE base material layer passes through between the coating roller and the first receiving roller.

[0010] Furthermore, the structures of the first cooling mechanism and the second cooling mechanism are the same, and both include a cooling roller.

[0012] Furthermore, a second receiving roller is installed directly below the sintered sand layer roller, and the HDPE base material layer passes through between the sintered sand layer roller and the second receiving roller.

[0013] Furthermore, a third receiving roller is installed directly below the separator film layer roller, and the HDPE base material layer passes through between the separator film layer roller and the third receiving roller.

[0021] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present utility model as follows.

[0022] As Figure 1-2 shown, a pre-laid waterproof coiled material production device includes a frame, on which an unwinding roller 2, a first glue coating mechanism, a first cooling mechanism, a sintered sand layer roller 3, a second glue coating mechanism, a second cooling mechanism, an isolation film layer roller 4 and a rewinding roller 5 are installed. The first glue coating mechanism is used to apply hot melt adhesive to one side of the HDPE substrate layer 1, and the second glue coating mechanism is used to apply hot melt adhesive to the other side of the HDPE substrate layer 1;

[0023] The first glue coating mechanism and the second glue coating mechanism have the same structure, and both include a glue spraying machine 10, a coating roller 11 and a first receiving roller 12 arranged in sequence from top to bottom. The nozzle of the glue spraying machine 10 is aligned with the coating roller 11. The HDPE substrate layer 1 passes through between the coating roller 11 and the first receiving roller 12. The hot melt adhesive is sprayed on the coating roller 11 by the glue spraying machine 10, and then the coating roller 11 cooperates with the first receiving roller 12 to apply the hot melt adhesive on the HDPE substrate layer 1;

[0024] The first cooling mechanism and the second cooling mechanism have the same structure, and both include a cooling roller 13. The inside of the cooling roller 13 is a hollow structure. Rotary joints are installed at both ends of the cooling roller 13. The two rotary joints are respectively connected with a liquid inlet pipe 14 and a liquid discharge pipe 15. The coolant is discharged into the inside of the cooling roller 13 through the liquid inlet pipe 14, so that the surface of the cooling roller 13 can cool the hot melt adhesive applied on the surface of the HDPE substrate layer 1, and the heated coolant will be discharged through the liquid discharge pipe 15;

[0025] A second receiving roller 16 is installed directly below the sintered sand layer roller 3. The HDPE substrate layer 1 passes through between the sintered sand layer roller 3 and the second receiving roller 16. A third receiving roller 17 is installed directly below the isolation film layer roller 4. The HDPE substrate layer 1 passes through between the isolation film layer roller 4 and the third receiving roller 17;

[0026] The rack includes a bottom plate 6, a support plate 7 and a top plate 8. The top plate 8 is located directly above the bottom plate 6. The right sides of the bottom plate 6 and the top plate 8 are both fixedly connected to the support plate 7. The unwinding roller 2, the first glue coating mechanism, the first cooling mechanism and the sintered sand layer roller 3 are sequentially installed on the top of the bottom plate 6 from left to right. The second glue coating mechanism, the second cooling mechanism, the isolation film layer roller 4 and the winding roller 5 are sequentially installed on the bottom of the top plate 8 from right to left. A buffer roller 9 is installed on one side of the support plate 7 close to the bottom plate 6. The HDPE substrate roll to be processed is installed on the unwinding roller 2, so that one side of the HDPE substrate layer 1 faces upward and sequentially passes through the first glue coating mechanism, the first cooling mechanism and the sintered sand layer roller 3, completing the processing of applying hot melt adhesive from the inside to the outside and pasting the sintered sand layer on one side of the HDPE substrate layer 1. Then the HDPE substrate layer 1 passes through the buffer roller 9 to complete reverse conveyance, so that the other side of the HDPE substrate layer 1 faces upward and sequentially passes through the second glue coating mechanism, the second cooling mechanism and the isolation film layer roller 4, completing the processing of applying hot melt adhesive from the inside to the outside and pasting the isolation film layer on the other side of the HDPE substrate layer 1. Finally, winding is completed through the winding roller 5.

[0027] Working principle:

[0028] As Figure 1-2 shown, when the pre-laid waterproofing membrane production equipment is in use, the operator first installs the HDPE substrate roll to be processed on the unwinding roller 2, so that one side of the HDPE substrate layer 1 faces upward and sequentially passes through the first glue coating mechanism, the first cooling mechanism and the sintered sand layer roller 3. When the HDPE substrate layer 1 passes between the coating roller 11 and the first receiving roller 12 of the first glue coating mechanism, the glue spraying machine 10 sprays the hot melt adhesive on the coating roller 11, and the coating roller 11 cooperates with the first receiving roller 12 to apply the hot melt adhesive on one side of the HDPE substrate layer 1. Then the HDPE substrate layer 1 coated with hot melt adhesive will adhere to and pass through the upper surface of the cooling roller 13 of the first cooling mechanism, and the cooling roller 13 will cool the hot melt adhesive. The HDPE substrate layer 1 will pass through between the sintered sand layer roller 3 and the second receiving roller 16 with the cooled hot melt adhesive, and the sintered sand layer roller 3 will extrude and paste the sintered sand layer on the surface of the HDPE substrate layer 1;

[0029] Then, the HDPE substrate layer 1 after the first processing will be reversely conveyed through the buffer roller 9, so that the other side of the HDPE substrate layer 1 faces upward and passes through the second gluing mechanism, the second cooling mechanism, and the separator film layer roller 4 in sequence. When the HDPE substrate layer 1 passes between the coating roller 11 and the first receiving roller 12 of the second gluing mechanism, the hot melt adhesive is sprayed on the coating roller 11 by the hot melt adhesive spraying machine 10. Then, the coating roller 11 cooperates with the first receiving roller 12 to apply the hot melt adhesive on the other side of the HDPE substrate layer 1. After that, the HDPE substrate layer 1 coated with the hot melt adhesive will be attached and pass through the upper surface of the cooling roller 13 of the second cooling mechanism, and the cooling roller 13 will cool the hot melt adhesive. The HDPE substrate layer 1 will pass between the separator film layer roller 4 and the third receiving roller 17 with the cooled hot melt adhesive, and the separator film layer roller 4 will extrude and paste the separator film layer on the surface of the HDPE substrate layer 1. Finally, the HDPE substrate layer 1 with both sides processed will be wound up by the winding roller 5.
