Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating mechanism technology, and in particular to a coating mechanism for producing self-adhesive geotextiles. Background Technology
[0002] In the production process of self-adhesive geotextiles, coating is a crucial step, as its quality directly affects the performance and effectiveness of the geotextile. Self-adhesive geotextiles, with their excellent self-adhesion, are widely used in numerous fields such as construction, roads, and water conservancy. With the continuous growth of market demand for self-adhesive geotextiles, the requirements for their production efficiency and quality are also increasing. Therefore, developing a high-efficiency, stable coating mechanism that can adapt to different production needs is particularly urgent. This coating mechanism needs to have precise coating control capabilities to ensure that the self-adhesive is evenly applied to the geotextile, while also being able to handle the coating requirements of fabrics of different thicknesses, improving production flexibility and applicability.
[0003] Currently, in the coating process of self-adhesive geotextile production, some companies use traditional roller coating machinery. This structure mainly consists of a coating roller, a pressure roller, and a feeding system. During operation, the feeding system delivers the self-adhesive to the surface of the coating roller, and the coating roller and pressure roller work together to transfer the self-adhesive onto the geotextile through pressure. Parameters such as the rotational speed and pressure of the coating roller and pressure roller affect the coating effect. In addition, some machinery uses a doctor blade coating system, which uses a doctor blade to evenly coat the self-adhesive onto the geotextile surface. The technical principle of these machinery mainly relies on the movement and pressure of mechanical parts to achieve self-adhesive coating. However, when dealing with fabrics of different thicknesses, manual adjustment of coating parameters is often required, making the operation cumbersome.
[0004] However, existing coating mechanisms for self-adhesive geotextile production have a significant problem: they cannot easily and uniformly coat fabrics of varying thicknesses. In actual production, the thickness of self-adhesive geotextiles varies depending on different application scenarios and customer needs. Traditional coating mechanisms often struggle to adapt automatically to varying fabric thicknesses. They either require frequent manual adjustments to coating parameters, which not only increases the workload of operators but also easily leads to untimely or inaccurate adjustments, resulting in uneven coating; or they can only coat fabrics of specific thicknesses, failing to meet diverse production needs and significantly limiting production efficiency and product applicability. Therefore, a new coating mechanism for self-adhesive geotextile production is proposed to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a coating mechanism for producing self-adhesive geotextiles, which aims to improve the problem that existing technologies cannot easily and uniformly coat fabrics of different thicknesses.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A coating mechanism for producing self-adhesive geotextile includes a frame, a back roller rotatably connected inside the frame, a placement plate inside the frame, a coating die inside the placement plate, an adjustment component on the outer wall of the placement plate, and a disassembly and assembly component inside the placement plate.
[0008] The adjustment assembly includes two sliders and a fixed post. The outer walls of the two sliders are fixedly connected to both sides of the placement plate. A fixed block is fixedly connected to the outer wall of the frame. One end of the fixed post is fixedly connected to the outer wall of the fixed block. The slider is slidably connected to the outer wall of the fixed post. A limit groove is formed inside the frame. The outer wall of the slider is slidably connected to the inside of the limit groove. A spring is sleeved on the outer wall of the fixed post. One end of the spring is fixedly connected to the outer wall of the fixed block, and the other end of the spring is fixedly connected to the outer wall of the slider.
[0009] As a further description of the above technical solution:
[0010] The assembly / disassembly assembly includes a connecting post, a retaining post, and a retaining groove formed inside the coating die head, with the outer wall of the retaining post slidably connected to the inside of the retaining groove.
[0011] As a further description of the above technical solution:
[0012] One end of the connecting post is fixedly connected to the outer wall of the card post, and the other end of the connecting post is fixedly connected to a knob.
[0013] As a further description of the above technical solution:
[0014] The outer wall of the placement plate is fixedly connected to a fixed outer shell, and the outer wall of the connecting column is slidably connected inside the fixed outer shell.
[0015] As a further description of the above technical solution:
[0016] The outer wall of the connecting column is rotatably connected to a limiting ring, and the outer wall of the limiting ring is slidably connected inside the fixed outer shell.
[0017] As a further description of the above technical solution:
[0018] The coating die head has a rotating groove inside and a sliding groove inside.
[0019] As a further description of the above technical solution:
[0020] A second spring is fitted on the outer wall of the connecting column. One end of the second spring is fixedly connected to the inner wall of the fixed outer shell, and the other end of the second spring is fixedly connected to the outer wall of the limiting ring.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the placement plate moves according to the thickness of the fabric label. The thickness pushes the coating die head, which moves the slider and compresses and rebounds the spring, so as to achieve close contact between the coating die head and the fabric, thereby improving uniformity and adaptively coating different fabrics stably. This solves the problem of not being able to easily coat fabrics of different thicknesses evenly, and improves the applicability of the device.
[0023] 2. In this utility model, the locking column moves by rotating the knob. When the knob is rotated, the connecting column is moved by the knob, which drives the locking column to slide. With the help of the second spring, the locking column slides inside the slot, which makes it easy to disassemble and assemble the coating die head, and facilitates its maintenance, replacement and movement. This solves the problem that the existing disassembly and assembly requires multiple tools and is not easy to disassemble, thus improving the convenience of the device. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a coating mechanism for producing self-adhesive geotextiles, including a frame 1, which serves as the basic support for the entire coating mechanism. The frame 1 is welded from high-strength steel and its structure is carefully designed to provide excellent stability and load-bearing capacity, capable of withstanding various forces generated during the coating process. A back roller 9 is rotatably connected inside the frame 1. The back roller 9 provides stable traction for the self-adhesive geotextile, ensuring that the fabric passes through the coating area smoothly and at a uniform speed during the coating process. A placement plate 7 is installed inside the frame 1. The placement plate 7 is made of aluminum alloy, which is lightweight and high-strength. Its interior is precision-machined and includes a cavity specifically for installing a coating die 8. The coating die 8 is installed inside the placement plate 7. Adjustment components are installed on the outer wall of the placement plate 7, and disassembly / removal components are installed inside the placement plate 7.
[0031] The adjustment assembly includes two sliders 2 and a fixed post 5. The outer walls of the two sliders 2 are fixedly connected to both sides of the placement plate 7. The sliders 2 have precise through holes inside, and their interiors are connected to the outer walls of the fixed post 5 through a high-precision sliding fit. A fixed block 4 is fixedly connected to the outer wall of the frame 1. One end of the fixed post 5 is fixedly connected to the outer wall of the fixed block 4. The sliders 2 are slidably connected to the outer wall of the fixed post 5. A limit groove 6 is opened inside the frame 1. The outer wall of the sliders 2 is slidably connected to the inside of the limit groove 6. A spring 3 is sleeved on the outer wall of the fixed post 5. One end of the spring 3 is fixedly connected to the outer wall of the fixed block 4, and the other end of the spring 3 is fixedly connected to the outer wall of the sliders 2.
[0032] Specifically, in the coating operation of self-adhesive geotextile production, the fabric is first pulled forward smoothly by the back roller 9. As the fabric moves forward, it pushes the coating die head 8 according to its thickness. When the coating die head 8 is under force, it will drive the external placement plate 7 connected to it to move together. Slider 2 is installed on both sides of the placement plate 7. During the process of being driven, the slider 2 will slide inside the limiting groove 6. At the same time, the slider 2 will also slide on the outer wall of the fixed column 5. The fixed column 5 plays a limiting role and ensures the stability of the overall movement. During the sliding of the slider 2, the spring 3 will be compressed. The spring 3 has a rebound characteristic and will quickly rebound after being compressed. Using this rebound force, the coating die head 8 is pushed into close contact with the fabric, which greatly improves the uniformity and accuracy of the fabric coating.
[0033] Reference Figures 1-3 The assembly and disassembly components include a connecting post 18, a locking post 16, and a locking groove 17 inside the coating die head 8. The outer wall of the locking post 16 is slidably connected to the inside of the locking groove 17. One end of the connecting post 18 is fixedly connected to the outer wall of the locking post 16, and the other end of the connecting post 18 is fixedly connected to a knob 10. The knob 10 is made of engineering plastic and its surface is treated with anti-slip material. Its design conforms to ergonomics and is convenient for operators to hold and rotate. The outer wall of the placement plate 7 is fixedly connected to a fixed housing 11. The outer wall of the connecting post 18 is slidably connected to the inside of the fixed housing 11. The outer wall of the connecting post 18 is rotatably connected to a limiting ring 12. The outer wall of the limiting ring 12 is slidably connected to the inside of the fixed housing 11. The limiting ring 12 is made of brass and its inner wall is finely bored to ensure smooth rotation with the connecting post 18. The outer wall of the limiting ring 12 can slide inside the fixed housing 11, and its outer diameter is precisely matched with the inner diameter of the fixed housing 11, which plays a role in limiting and guiding the connecting column 18. The coating die head 8 has a rotating groove 15 and a sliding groove 14 inside. The outer wall of the connecting column 18 is fitted with a second spring 13. One end of the second spring 13 is fixedly connected to the inner wall of the fixed housing 11, and the other end of the second spring 13 is fixedly connected to the outer wall of the limiting ring 12.
[0034] Specifically, during the production of self-adhesive geotextiles, after the coating operation has lasted for a long time, maintenance of the coating die 8 is an essential operation to ensure coating quality. When maintenance is required, the operator can first press the knob 10. Pressing the knob 10 will move the connecting column 18. As the connecting column 18 moves, it will cause the locking column 16 to slide out from the locking groove 17 and into the rotating groove 15. During this process, the connecting column 18 will also cause the limiting ring 12 to slide inside the fixed shell 11, thereby compressing the second spring 13. Then, turn the knob 10. The rotation of the knob 10 will cause the locking column 16 to rotate together until the locking column 16 is aligned with the sliding groove 14. At this time, release the knob 10. Due to its rebound characteristic, the second spring 13 will cause the locking column 16 to slide out from the sliding groove 14, thereby disconnecting the coating die 8. This allows for convenient maintenance, ensuring that it always maintains a stable working state, and thus ensuring the production quality of the self-adhesive geotextile.
[0035] Working principle: When applying the coating to the fabric, the back roller 9 pulls the fabric, and the thickness of the fabric pushes the coating die head 8. The coating die head 8 then drives the external placement plate 7 to move. The placement plate 7 then drives the sliders 2 on both sides to slide inside the limiting groove 6, and the sliders 2 slide on the outer wall of the fixed column 5 to limit their movement. At the same time, the spring 3 is compressed, and the spring 3 rebounds to make the coating die head 8 and the fabric in close contact, improving the uniformity and accuracy of the coating.
[0036] Additionally, when maintenance is required after a long coating period, first press the knob 10. The knob 10 will move the connecting post 18, causing the locking post 16 to slide out of the slot 17 and into the rotating slot 15. The connecting post 18 will then move the limiting ring 12 inside the fixed housing 11, compressing the second spring 13. Then, turn the knob 10 to rotate the locking post 16, aligning it with the sliding slot 14. Finally, release the knob 10, and the second spring 13 will rebound, causing the locking post 16 to slide out of the sliding slot 14. This will disconnect the coating die head 8, facilitating maintenance and ensuring stable operation.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
