Traditional embossing rollers are mostly one-piece structures, and the patterns cannot be changed after engraving. If different patterns are to be produced, the entire precision embossing roller assembly must be disassembled and replaced from the equipment, which is costly and time-consuming, and cannot meet the market's demand for multi-variety, small-batch production.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] like Figure 1-2 As shown, the waterproof material forming device includes a frame 1 and a pressing mechanism. The pressing mechanism includes a rough pressing mechanism and a fine pressing mechanism arranged sequentially along the material feeding direction.

[0016] The precision pressing mechanism includes a lower precision pressing roller 2 fixedly mounted on the frame 1 and an upper precision pressing roller body 3 located above it. The upper precision pressing roller body 3 is connected to the frame 1 via a lifting mechanism. The lifting mechanism is an H-type screw structure, including four worm gear screw jacks 5 and a drive motor 6. The drive motor 6 is a servo motor and is fixed to the frame 1. The four worm gear screw jacks 5 are connected as a whole through a commutator 9, a coupling 8, and a connecting rod 7, and are driven synchronously by a servo motor.

[0017] The upper precision pressure roller body 3 is fixedly connected to the output ends of four worm gear screw jacks 5 via a rigid lifting platform 17. The upper precision pressure roller body 3 includes a base roller 4 and a textured sleeve 10 disposed outside the base roller. The textured sleeve 10 has a split structure, including an upper sleeve 11 and a lower sleeve 12 that fit together, and is fixed to the base roller 4 by a split locking ring 13 at the end.

[0018] In the above embodiment, the connecting rod 7 is a universal coupling and the commutator 9 is a right-angle commutator.

[0019] In the above embodiment, the coarse pressing mechanism includes an upper coarse pressing roller 19 and a lower coarse pressing roller 20 that cooperate with each other. Both ends of the upper coarse pressing roller 19 are connected to nuts on two coarse pressing mechanism lead screws 21 via bearing seats. One active coarse pressing mechanism lead screw 21 is driven by a stepper motor, and this active lead screw 21 drives the other driven lead screw 21 to rotate synchronously through a closed belt transmission system 22. In this way, the nuts on the two coarse pressing mechanism lead screws 21 can rise and fall synchronously, thereby driving the upper coarse pressing roller 19 to move smoothly up and down, so as to perform preliminary compaction and thickness regularization of the material. The surface of the upper coarse pressing roller 19 is covered with a silicone layer to avoid damaging the material during the pre-pressing process.

[0020] In the above embodiments, to ensure the alignment of the two lobes after they are joined together, the mating split surface of the textured sleeve 10 is machined with a precise positioning structure, such as a wedge surface or a serrated surface.

[0021] In the above embodiment, an electric heating tube is arranged axially inside the base roller 4, which can heat to a set temperature during operation, and the heat is conducted to the texture sleeve 10 through the base roller 4. The lower precision roller 2 is also equipped with an electric heating tube, which is independently controlled by an external temperature control system to maintain a constant working temperature.

[0022] In the above embodiment, the inner wall of the textured sleeve 10 is provided with axial heat dissipation fins 18 to enhance the heat dissipation effect.

[0023] In the above embodiment, the split locking ring 13 is locked by bolts 14 and disc springs 15.

[0024] The working principle of this utility model is as follows: First, the material enters the coarse pressing mechanism via a conveying system. The upper coarse pressing roller 19 descends under the drive of a stepper motor, belt 22, and lead screw 21, cooperating with the lower coarse pressing roller 20 to initially compact the material. The silicone coating provides compressive strength while preventing damage to the material surface.

[0025] Subsequently, the pre-compressed material enters the fine pressing area. The electric heating tubes inside the base roller 4 and the lower fine pressing roller 2 are activated, heating the roller surface to the set temperature. The heat is conducted through the base roller 4 to the textured sleeve 10, and the axial heat dissipation fins 18 on the inner wall of the sleeve enhance the heat dissipation effect.

[0026] Once the temperature reaches the set value, the servo motor drives four worm gear screw jacks 5 to run synchronously through the transmission system consisting of commutator 9, coupling 8 and connecting rod 7, which in turn drives the upper precision pressure roller body 3 to descend.

[0027] During the pressing process, the heated textured sleeve 10 and the lower precision roller 2 work together on the material surface. The heat softens the material surface, and the pressure imprints the micro-texture of the sleeve surface onto the material surface. The inherent self-locking characteristic of the worm gear screw jack 5 ensures a stable working pressure throughout the pressing process, thereby guaranteeing the clarity and consistency of the texture transfer.

[0028] When it is necessary to change the product pattern, the operator first raises the upper pressure roller 3 to the maintenance position. After loosening the bolt 14 of the split locking ring 13, the textured sleeve 10 can be disassembled into the upper sleeve 11 and the lower sleeve 12 that close together for replacement. The disc spring 15 provides a constant preload during the locking process, ensuring that the textured sleeve 10 remains stable in the working state.

[0029] The entire process, through graded coarse and fine pressing, ensures both molding quality and rapid pattern change. The stable coordination between the heating and pressure systems guarantees effective texture transfer, improving production efficiency and product quality.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
