Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, and in particular to a single-sided embossed component and membrane of EPDM rubber waterproof membrane. Background Technology

[0002] To facilitate bonding with other materials during use, single-sided EPDM waterproof membranes often have patterns pressed onto their surface. These are typically produced using drum vulcanizing machines (such as the rubber vulcanizing machine disclosed in CN117921912B). Custom-made high-temperature resistant cord fabric is required for printing these patterns, and a pre-impregnation anti-adhesion agent is used. While this results in aesthetically pleasing patterns, the fabric is prone to aging and damage with repeated use. It is also susceptible to edge folding and misalignment during use, necessitating unwinding and rewinding, and the installation of anti-misalignment devices. This affects product quality and incurs losses. Furthermore, the need for manual maintenance, replacement, and operation makes the process relatively cumbersome. Additionally, each type of cord fabric can only be used with one type of membrane, leading to high replacement costs and a more complex operational process. Utility Model Content

[0003] Therefore, in order to solve the above problems and shortcomings, this utility model provides a single-sided embossing component for EPDM rubber waterproof membrane, including an embossing roller, a secondary drum, an upper drum, and a lower drum arranged in parallel and rotating manner. The surface of the embossing roller is provided with a pattern. The upper drum and the lower drum are arranged opposite each other and close to one side of the embossing roller. The secondary drum is located on the other side of the embossing roller and is away from the embossing roller. The steel strip enters through the gap between the lower drum and the embossing roller, surrounds the embossing roller, and then exits through the gap between the upper drum and the embossing roller. It is then pulled back to the lower drum through the auxiliary drum to form a closed loop.

[0004] Preferably, the embossing roller includes a drum body, a drum surface, a limiting hole, a docking hole, and a docking pin. The drum body is a hollow structure, the drum surface is patterned, and the drum surface covers the surface of the drum body and is connected to the drum body. The limiting hole penetrates the center of the drum body, and the docking hole and the docking pin are symmetrically distributed in pairs on both sides of the drum body near the limiting hole.

[0005] Preferably, it also includes a drive shaft and a locking disc, wherein the embossing roller is nested on the drive shaft and kept in a limited position between the drive shaft and the drive shaft, and the locking disc is threaded to both ends of the drive shaft.

[0006] Preferably, any two embossing rollers are connected in a compatible manner through a mating hole and a mating pin.

[0007] Preferably, the secondary drum is kept in a horizontal position by hydraulic rods located on both sides thereon.

[0008] Preferably, the drum surface is an embossed electroplated roller surface.

[0009] In addition, this utility model also provides a EPDM rubber waterproof membrane, which is obtained by vulcanization extrusion molding of any of the above-mentioned EPDM rubber waterproof membrane single-sided embossed components.

[0010] Preferably, the EPDM rubber waterproof membrane includes a membrane body, which includes a substrate layer and a backing layer. The upper surface of the substrate layer has an embossed surface, and the backing layer is disposed on the lower surface of the substrate layer and integrally formed.

[0011] Preferably, the substrate layer is EPDM rubber and the backing layer is nonwoven fabric.

[0012] The beneficial effects of this utility model can be specifically analyzed as follows: 1. During the embossing process of EPDM rubber waterproof membrane, the upper drum, embossing roller, lower drum, and steel belt provide compression and auxiliary traction. Simultaneously, the tension can be adjusted via an auxiliary drum, making the embossing process smoother. 2. The embossing roller has been improved by replacing it with an electroplated roller, which not only improves the anti-sticking performance of the roller surface and ensures that the rubber does not stick to the roller, but also makes the embossing uniform and reduces the number of maintenance and upkeep cycles. Only the main roller needs to be cleaned a few times a year.

[0013] 3. The product manufacturing process abandons the traditional embossing process for curtain fabric, saving the cost of curtain fabric consumption every year, reducing production costs, and ensuring stable product quality.

[0014] 4. Different embossing rollers can be selected according to production or customization requirements, and the embossing rollers can be used to replace the traditional main rollers. They can be used in conjunction with a drum vulcanizing machine. In the entire embossing process, from selecting and replacing the embossing rollers to the final embossing and pressing, the operation is relatively simple for the workers, the number of procedures is reduced and the labor intensity is decreased.

Detailed Implementation

[0016] The present invention will now be described in detail with reference to the accompanying drawings, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Throughout the invention, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. It should be understood that ordinal numbers and directional descriptions, such as "first," "second," "third," "upper," "lower," "left," and "right," are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly and not as limiting the scope of this utility model.

[0017] The preferred embodiment of this utility model is described in detail below with reference to the accompanying drawings and specific embodiments. Please refer to the attached drawings. Figure 1 As shown, this application provides a EPDM rubber waterproof membrane, which is obtained by vulcanization extrusion molding of a single-sided embossed component. It includes a membrane body, which consists of a substrate layer 10 and a backing layer 20. The backing layer 20 is disposed on the lower surface of the substrate layer 10 and integrally molded. The upper surface of the substrate layer 10 has an embossed surface 101. The embossed surface 101 is usually striped or mesh-like, which facilitates bonding with other materials during use.

[0018] In this embodiment, the sealing substrate layer 10 is EPDM rubber, and the backing layer 20 is non-woven fabric.

[0019] In addition, please see Figure 2-4 As shown, this utility model also discloses a single-sided embossing assembly for EPDM rubber waterproof membrane, including an embossing roller 40, a secondary drum 50, an upper drum 60, and a lower drum 70 arranged in parallel and rotating manner. The surface of the embossing roller 40 is provided with a pattern. The upper drum 60 and the lower drum 70 are arranged vertically opposite each other and close to one side of the embossing roller 40. The secondary drum 50 is arranged on the other side of the embossing roller 40 and away from the embossing roller 40. The steel strip 30 enters through the gap between the lower drum 70 and the embossing roller 40, surrounds the embossing roller 40, exits through the gap between the upper drum 60 and the embossing roller 40, and returns to the lower drum 70 through the surface of the auxiliary drum 50 to form a closed loop.

[0020] Based on the above characteristics, during the embossing process of the embossing roller 40, the roll material body is squeezed and assisted by the upper drum 60, the embossing roller 40, the steel belt 30 and the lower drum 70. At the same time, the tension can be adjusted by the auxiliary drum 50, making the embossing process smoother.

[0021] like Figure 3As shown, the embossing roller 40 includes a drum body 401, a drum surface 402, a limiting hole 403, a docking hole 404, and a docking pin 407. The drum body 401 is a hollow structure, the drum surface 402 is patterned and covers the surface of the drum body 401 and is connected to the drum body 401. The limiting hole 403 passes through the center of the drum body 401. The docking hole 404 and the docking pin 407 are symmetrically distributed on both sides of the drum body 401 near the limiting hole 403. It also includes a drive shaft 405 and a locking disc 406. The embossing roller 40 is nested on the drive shaft 405 and is limited between the drive shaft 405 and the drive shaft 405. The locking disc 406 is threaded to both ends of the drive shaft 405. The drum surface 402 is an embossing electroplating roller surface.

[0022] As one embodiment, it should be noted that the embossed surface 101 of the substrate layer 10 is determined by the pattern engraved on the drum surface 402. The drum surface 402 and drum body 401 are important parts of the embossing roller 40. The heating component inside the drum body 401 raises the temperature of the drum surface 402 (generally 180-220℃). Through the high temperature and the high pressure generated by the upper drum 60 and lower drum 70 pressing the embossing roller 40, a pattern is automatically formed on the lower surface of the substrate layer 10. This pattern can be consistent with the pattern formed by the tire cord lining, thus achieving the replacement of the tire cord fabric with a rigid, permanent embossing roller 40, improving product quality and effectively saving enterprise costs. Equipment maintenance and upkeep are also reduced, requiring only a few cleanings of the main roller per year. More importantly, it saves on the annual cost of tire cord fabric consumption and improves the product's appearance quality.

[0023] Meanwhile, the improved embossing roller 40 is an electroplated roller, which enhances the anti-sticking performance of the roller surface. Furthermore, by improving the rubber compound formula, selecting special additives, and adjusting the rubber compound's viscosity, it is ensured that the rubber compound does not stick to the roller, further resulting in more uniform embossing.

[0024] like Figure 3-4 As shown, any two embossing rollers 40 are connected to each other through mating holes 404 and mating pins 407; the auxiliary drum 50 is kept in a horizontal position by hydraulic rods set on both sides of it.

[0025] Based on the above characteristics, firstly, different embossing rollers 40 need to be selected according to production or customization requirements and fitted onto the drive shaft 405 to maintain their position. At the same time, adjacent embossing rollers 40 are connected to each other through the mating holes 404 and the mating pins 407 to minimize the gap between them. Then, the locking discs 406 at both ends of the drive shaft 405 are tightened to lock the embossing rollers 40 together and installed on the vulcanizing machine main roller mounting seat. The embossing rollers 40 replace the traditional main rollers and are used in conjunction with a drum vulcanizing machine. The unembossed and unvulcanized EPDM waterproof membrane first passes through the upper surface of the lower drum 70 and is pulled and squeezed to surround the embossing roller 40. It is then squeezed tightly against the embossing roller 40 by the steel belt 30. The membrane is vulcanized by high temperature and high pressure and the pattern is formed on its surface. Then, it passes through the upper drum 60 to ensure that the substrate layer 10 does not fold or deviate. Finally, the embossed membrane is pulled by the auxiliary drum 50 and enters the next process. Throughout the embossing process, from selecting and replacing the embossing roller 40 to the final embossing and pressing, the operation is relatively simple for the workers, with fewer steps and reduced labor intensity.

[0026] This utility model relates to a single-sided embossing component for EPDM waterproof membranes. By improving the embossing roller of the embossing component, it enables high-temperature and high-pressure automatic embossing of EPDM waterproof membranes, thereby replacing the embossing process of the curtain fabric lining. This not only effectively saves labor and curtain fabric costs, but also improves the appearance quality of the waterproof membrane products.

[0027] The above are merely embodiments of this utility model. Common knowledge such as specific structures and characteristics in the solutions are not described in detail here. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and they will not affect the implementation effect of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
