Description

Technical Field

[0001] This utility model relates to the field of geotextile processing technology, and in particular to a pressing device for geotextile processing. Background Technology

[0002] Geotextile, also known as geotextile fabric, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. Geotextile is one of the new geosynthetic materials. The finished product is cloth-like, generally 4-6 meters wide and 50-100 meters long. Geotextile is divided into woven geotextile and non-woven filament geotextile. In the field of geotextile processing, geotextile is widely used in many projects such as water conservancy, roads, and environmental protection due to its excellent filtration, isolation, and reinforcement properties. The edge pressing is a key step in geotextile processing and has a significant impact on product quality and performance.

[0003] Traditional geotextile edge pressing devices have significant drawbacks. Most existing devices have fixed pressing plate positions that cannot be flexibly adjusted. In actual production, geotextiles come in a wide variety of specifications and sizes, and different projects require geotextiles with varying widths and thicknesses. When dealing with geotextiles of different specifications, it is difficult to accurately align the fixed pressing plate with the edge of the geotextile, which can easily lead to edge pressing position deviations. This not only results in poor edge pressing of the geotextile, such as insecure pressing and missed pressing, reducing product quality and increasing the defect rate, but also causes the processed geotextile to fail to meet actual usage requirements, resulting in material waste. Therefore, a geotextile edge pressing device is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pressing device for geotextile processing, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pressing device for geotextile processing includes a base plate, a placement plate fixedly installed on the top side of the base plate, a connecting block provided above the base plate, a through hole provided in the connecting block, a spacing adjustment component provided in the through hole, two connecting rods respectively provided in the through hole through the spacing adjustment component, a pressure plate fixedly connected to the bottom side of each of the two connecting rods, both pressure plates facing the placement plate, a sliding hole provided on the top side of the base plate, two positioning plates slidably installed in the sliding hole, the other side of the two positioning plates being fixedly connected to one side of the two pressure plates respectively, and a limit component provided above the connecting block.

[0007] Preferably, the spacing adjustment assembly includes a fixing plate fixedly installed on the top side of the connecting block. The fixing plate is U-shaped, and a circular hole is opened on the top side of the fixing plate. A rotating rod is installed in the circular hole, and a gear is fixedly sleeved on the outside of the rotating rod.

[0008] Preferably, the outer side of the gear is provided with a first tooth plate and a second tooth plate, both of which mesh with the gear, and the top sides of the two connecting rods are fixedly connected to the bottom sides of the first tooth plate and the second tooth plate, respectively.

[0009] Preferably, the limiting assembly includes a handwheel fixedly connected to the top of the rotating rod, a threaded hole and multiple threaded grooves respectively opened on the top side of the handwheel and the fixed plate, a threaded post is threadedly installed in the threaded hole, and the other end of the threaded post is threadedly installed into the threaded groove aligned with the threaded hole. Two limiting rings are fixedly sleeved on the outer side of the rotating rod, and the sides of the two limiting rings that are close to each other are respectively in contact with the top and bottom sides of the fixed plate.

[0010] Preferably, guide grooves are provided on both inner walls of the through hole, and guide blocks are slidably installed in both guide grooves. The side of the two guide blocks that are close to each other is fixedly connected to the side of the first toothed plate and the side of the second toothed plate that are far from each other.

[0011] Preferably, two cylinders are fixedly installed on the bottom side of the base plate, and the output ends of the two cylinders pass through the base plate and are fixedly connected to the bottom side of the connecting block.

[0012] Preferably, a first switch and a second switch are respectively provided on the top side of the base plate, and both the first switch and the second switch are electrically connected to the two cylinders.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the cooperation of handwheel, rotating rod and gear, the spacing of the pressure plate can be adjusted as needed. When dealing with large-sized geotextile, turn the handwheel counterclockwise, and the gear will drive the first tooth plate and the second tooth plate to move away from each other, so that the pressure plate moves outward synchronously. When dealing with small-sized geotextile, turn the handwheel clockwise to move the pressure plate inward. The positioning plate is fixed to the pressure plate, providing a reference for the movement of the pressure plate, ensuring accurate alignment with the edge of the geotextile, avoiding edge pressing position deviation, reducing the defect rate, and meeting the edge pressing requirements of geotextile of different specifications.

[0015] 2. By removing the threaded post before pressing the edge, the spacing between the pressing plates can be adjusted. After completion, screw it into the handwheel and the fixed plate to prevent the gear from rotating accidentally. Two limit rings restrict the rotating rod so that it can only rotate, ensuring that the gear and the toothed plate are always meshed. The guide block and guide groove guide and limit the movement of the toothed plate. In addition, the first switch and the second switch control the cylinder, simplifying the pressing and fabric picking process and greatly improving production efficiency. Attached Figure Description

[0021] 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.

[0022] Reference Figure 1-4A pressing device for geotextile processing includes a base plate 1, a placement plate 2 fixedly installed on the top side of the base plate 1, a connecting block 4 above the base plate 1, a through hole in the connecting block 4, a spacing adjustment component installed in the through hole, and two connecting rods 10 respectively installed in the through hole through the spacing adjustment component. A pressure plate 11 is fixedly connected to the bottom side of each of the two connecting rods 10, with both pressure plates 11 facing the placement plate 2. A sliding hole 20 is opened on the top side of the base plate 1, and two positioning plates 12 are slidably installed in the sliding hole 20. The other side of the two positioning plates 12... The connecting blocks 4 are fixedly connected to one side of the two pressure plates 11 respectively. A limit component is provided above the connecting block 4. The spacing adjustment component includes a fixing plate 5 fixedly installed on the top side of the connecting block 4. The fixing plate 5 is U-shaped and has a round hole on the top side. A rotating rod 6 is installed in the round hole. A gear 7 is fixedly sleeved on the outside of the rotating rod 6. A first toothed plate 8 and a second toothed plate 9 are respectively provided on the outside of the gear 7. Both the first toothed plate 8 and the second toothed plate 9 mesh with the gear 7. The top sides of the two connecting rods 10 are fixedly connected to the first toothed plate 8 and the second toothed plate 9 respectively. On the bottom side, a gear 7 is provided. When handling large-sized geotextile edge pressing, gripping the handwheel 14 and rotating it counterclockwise causes the connected rotating rod 6 to synchronously drive the gear 7 to rotate counterclockwise. Because the gear 7 meshes with the first toothed plate 8 and the second toothed plate 9 respectively, under the transmission of the gear 7, the first toothed plate 8 and the second toothed plate 9 will move away from each other, thus synchronously driving the pressing plates 11 below the two connecting rods 10 to move away synchronously. When handling small-sized geotextile edge pressing, simply rotate the handwheel 14 clockwise. Driven by gear 7, the two connecting rods 10 drive the pressure plates 11 to move closer to each other. During the movement of the pressure plates 11, the two positioning plates 12 can be used as references. When the positioning plates 12 move to both sides of the geotextile, the handwheel 14 can be stopped, thereby completing the adjustment of the distance between the two pressure plates 11. This positioning adjustment method can be used for edge pressing of geotextiles of different sizes. Furthermore, the bottom plate 1 has a sliding hole 20. When the cylinder 3 drives the connecting block 4 to move down, the two positioning plates 12 will move down synchronously in the sliding hole 20.

[0023] Specifically, the limiting assembly includes a handwheel 14 fixedly connected to the top of the rotating rod 6. The handwheel 14 and the top side of the fixing plate 5 each have a threaded hole 15 and multiple threaded grooves 16. A threaded post 17 is threaded into one of the threaded holes 15, and the other end of the threaded post 17 is threaded into the threaded groove 16 aligned with the threaded hole 15. Two limiting rings 18 are fixedly sleeved on the outer side of the rotating rod 6. The sides of the two limiting rings 18 that are close to each other are respectively in contact with the top and bottom sides of the fixing plate 5. By providing the threaded post 17, after the distance between the two pressure plates 11 is adjusted, the threaded post 17 is threaded into the threaded hole 15 of the handwheel 14. Then, by continuing to rotate the threaded post 17, the other end of the threaded post 17 can be threaded into the threaded groove 16 that is aligned with the threaded hole 15, thereby achieving a fixed connection between the handwheel 14 and the fixed plate 5. This avoids the situation where the gear 7 will rotate due to the lack of a limit. The limit of the threaded post 17 can prevent this situation from happening, ensuring that the pressing work is completed smoothly. By setting two limit rings 18, the two limit rings 18 can play a limiting role when the rotating rod 6 rotates, so that it can only rotate and will not tilt or move up and down, thereby ensuring that the gear 7 always meshes with the first toothed plate 8 and the second toothed plate 9.

[0024] Specifically, guide grooves 19 are provided on both sides of the through hole, and guide blocks 13 are slidably installed in both guide grooves 19. The side of the two guide blocks 13 that is close to each other is fixedly connected to the side of the first tooth plate 8 and the second tooth plate 9 that is far away from each other. By providing two guide blocks 13, the two guide blocks 13 can provide guidance and limit when the first tooth plate 8 and the second tooth plate 9 are close to each other or far away from each other, thereby ensuring that the first tooth plate 8 and the second tooth plate 9 are always meshed with the gear 7.

[0025] Specifically, two cylinders 3 are fixedly installed on the bottom side of the base plate 1. The output ends of the two cylinders 3 pass through the base plate 1 and are fixedly connected to the bottom side of the connecting block 4. A first switch 21 and a second switch 22 are respectively provided on the top side of the base plate 1. The first switch 21 and the second switch 22 are electrically connected to the two cylinders 3. By providing the first switch 21 and the second switch 22, and because the first switch 21 and the second switch 22 are electrically connected to the two cylinders 3, when it is necessary to press the edge, pressing the first switch 21 will make the two cylinders 3 run synchronously, and then drive the connecting block 4 to move down. After the edge pressing is completed, pressing the second switch 22 will make the two cylinders 3 drive the connecting block 4 to move up.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0027] In use: When performing geotextile edge pressing, first place the geotextile to be pressed on the placement plate 2. During placement, use two positioning plates 12 for precise positioning. Simply align the two sides of the geotextile with the positioning plates 12. After alignment, press the first switch 21, and the two cylinders 3 will start simultaneously. The output end of the cylinder 3 drives the connecting block 4, which is fixedly connected to it, to move downward. The two pressure plates 11 below the connecting block 4 then move towards the two sides of the geotextile. Since the two positioning plates 12 are fixed to one side of the two pressure plates 11 respectively, the pressure plates 11 can accurately align with the two sides of the geotextile when they move downward. As the cylinders 3 continue to operate, the two pressure plates 11 apply pressure to the edges of the geotextile, completing the edge pressing operation. After edge pressing is completed, press the second switch 22, and the two cylinders 3 drive the connecting block 4 to move upward. At this time, the pressed geotextile can be removed. When it is necessary to press the edges of geotextiles of different sizes... When processing geotextiles, first remove the threaded post 17 from the handwheel 14. Then, depending on the size of the geotextile, turn the handwheel 14 clockwise or counterclockwise. When processing large geotextiles, hold the handwheel 14 and turn it counterclockwise. The rotating rod 6 connected to the handwheel 14 will synchronously drive the gear 7 to rotate counterclockwise. Since the gear 7 meshes with the first toothed plate 8 and the second toothed plate 9 respectively, under the transmission action of the gear 7, the first toothed plate 8 and the second toothed plate 9 move away from each other, thereby synchronously driving the pressure plate 11 below the two connecting rods 10 to move outwards. When processing small geotextiles, simply turn the handwheel 14 clockwise. Under the transmission of the gear 7, the two connecting rods 10 drive the pressure plate 11 to move closer to each other. During the movement of the pressure plate 11, take the two positioning plates 12 as a reference. When the positioning plates 12 move to both sides of the geotextile, stop turning the handwheel 14. Finally, reinstall the threaded post 17 on the handwheel 14, and the edge pressing operation can begin.
