Description

Technical Field

[0001] This utility model relates to the field of glass fiber mesh production technology, and in particular to a laying device for glass fiber mesh production. Background Technology

[0002] Fiberglass mesh is a new type of alkali-resistant product made of woven fiberglass fabric as the base material and coated with a polymer anti-emulsion. It has good alkali resistance, flexibility and high tensile strength in both warp and weft directions. It is widely used in wall reinforcement, external wall insulation and roof waterproofing. In the production process of fiberglass mesh, the workbench is the core carrier for laying, transitioning and connecting the mesh to subsequent processing steps (such as coating and cutting).

[0003] When fiberglass mesh is conveyed and laid on the workbench by conveyor rollers, it is easy to deviate due to factors such as fluctuations in conveying speed, uneven stress on the edge of the mesh, or equipment vibration. The deviated mesh cannot be aligned with the processing area of ​​the subsequent coating equipment, resulting in incomplete coating and uneven coating thickness. This directly affects the core properties of the product, such as alkali resistance and tensile strength. The deviation will cause the mesh width to deviate, and the regularity of the finished mesh structure will decrease, which will not meet the dimensional accuracy requirements of application scenarios such as wall reinforcement and external wall insulation.

[0004] Currently, the method of manually observing and adjusting the offset during the conveying and laying of fiberglass mesh is mostly used to correct the offset. This method is not only labor-intensive and slow to respond, but also difficult to guarantee the accuracy of adjustment. Some simple anti-offset structures only limit the position with fixed baffles, which cannot be adapted to meshes of different widths and have poor versatility. Utility Model Content

[0005] To overcome the technical defects of existing technologies, this utility model provides a laying device for the production of glass fiber mesh.

[0006] The technical solution adopted by this utility model is: a laying device for producing glass fiber mesh cloth, including a processing table and four support legs installed on the bottom surface of the processing table. A U-shaped plate is fixedly connected to the upper surface of the processing table. A rotating shaft is fixedly connected to the center of the upper surface of the U-shaped plate. A gear is rotatably sleeved on the surface of the rotating shaft. Two parallel toothed rods are meshed on the surface of the gear. A limiting plate one is respectively provided below each of the toothed rods. A U-shaped frame is fixedly connected to the side of the two limiting plates one that is far away from each other. A threaded rod is provided below the U-shaped frame. Rotating the threaded rod is used to adjust the distance between the two limiting plates one. A limiting plate two is fixedly connected to the end of each U-shaped frame that is far away from the limiting plate one.

[0007] Preferably, each of the toothed rods and the limiting plate is fixedly connected to a connecting block, and the two connecting blocks are respectively inserted into the rectangular grooves opened on the surface of the U-shaped plate, and the connecting blocks and the U-shaped plate are slidably connected.

[0008] Preferably, each of the U-shaped frames has a lower connecting plate fixedly connected to its bottom surface. The threaded rod is inserted into a threaded hole opened inside one of the lower connecting plates. The threaded rod and the lower connecting plate are threadedly connected. One end of the threaded rod is rotatably connected to one side of the processing table through a bearing.

[0009] Preferably, each of the two U-shaped frames is fitted with a U-shaped locking block, the U-shaped locking block is fixedly connected to the upper surface of the processing table, and the U-shaped locking block and the U-shaped frame are slidably connected.

[0010] Preferably, inner sliding plates are inserted into the inner sliding grooves opened on the bottom surface of the two limiting plates, and springs are fixedly connected between the inner sliding plates and the limiting plates. The inner sliding plates and the limiting plates are slidably connected, and the bottom surface of the inner sliding plates is in contact with the upper surface of the processing table.

[0011] Preferably, the corners of adjacent sides of the two inner sliding plates are both arc-shaped, and the internal structures of the first limiting plate and the second limiting plate are the same.

[0012] Preferably, one end of the U-shaped frame is inserted into a groove opened on the surface of the U-shaped plate, the U-shaped frame and the U-shaped plate are slidably connected, and the surface of the U-shaped frame is inlaid with scale lines.

[0013] The beneficial effects of this utility model are: the rotating threaded rod can drive the U-shaped frame to slide along the U-shaped block, causing the first and second limiting plates to move synchronously. With the linkage of the gear and the rack, the two limiting plates can move synchronously in opposite directions. Combined with the scale lines on the surface of the U-shaped frame and the width marked on the mesh cloth, the width of the mesh cloth can be quickly adapted, improving the convenience and accuracy of adjustment.

[0014] The first and second limiting plates move synchronously to prevent the mesh cloth from shifting between the two limiting plates. The inner sliding plate adheres to the surface of the processing table under the action of the spring, preventing the mesh cloth from sliding into the space between the inner sliding plate and the processing table. The rounded corner design of the inner sliding plate can guide and correct the mesh cloth, ensuring alignment with the subsequent coating equipment and improving processing accuracy.

[0015] The connecting block slides within the rectangular groove of the U-shaped plate, and the U-shaped frame and U-shaped clamping block slide together to provide stable guidance for component movement and ensure the stability of the overall structure during mesh fabric conveying and processing.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1 to 5 As shown, this embodiment provides a laying device for producing fiberglass mesh, including a processing table 1 and four support legs 18 installed on the bottom surface of the processing table 1. A U-shaped plate 2 is fixedly connected to the upper surface of the processing table 1. A rotating shaft 4 is fixedly connected to the center of the upper surface of the U-shaped plate 2. A gear 5 is rotatably sleeved on the surface of the rotating shaft 4. Two parallel toothed rods 6 are meshed on the surface of the gear 5. A limiting plate 7 is provided below each toothed rod 6. A U-shaped frame 9 is fixedly connected to the side of the two limiting plates 7 that are far apart from each other. A threaded rod 12 is provided below the U-shaped frame 9. Rotating the threaded rod 12 is used to adjust the distance between the two limiting plates 7. A second limiting plate 10 is fixedly connected to the end of each U-shaped frame 9 that is far away from the limiting plate 7.

[0024] In this implementation scheme: through the meshing transmission of gear 5 and rack 6, the two limiting plates 7 can move synchronously in opposite directions to ensure symmetrical and precise spacing adjustment. At the same time, the limiting plates 7 and 10 are linked synchronously to form a bidirectional limit on the glass fiber mesh cloth conveyed on the processing table 1, preventing the mesh cloth from deviating from both ends of the conveying path and providing a stable base material position for subsequent processing steps.

[0025] Furthermore:

[0026] In an optional embodiment, each toothed rod 6 and the limiting plate 7 are fixedly connected with a connecting block 8. The two connecting blocks 8 are respectively inserted into the rectangular groove 3 opened on the surface of the U-shaped plate 2, and the connecting blocks 8 and the U-shaped plate 2 are slidably connected.

[0027] In this implementation scheme: the sliding fit between the connecting block 8 and the rectangular groove 3 can provide stable guiding constraints for the toothed rod 6 to drive the limiting plate 7 to move, avoid the toothed rod 6 to tilt laterally during the movement, ensure that the limiting plate 7 always moves along a trajectory parallel to the mesh fabric conveying direction, further improve the accuracy of the spacing adjustment, and ensure the stability of the mesh fabric limiting.

[0028] Furthermore:

[0029] In an optional embodiment, each U-shaped frame 9 is fixedly connected to a lower connecting plate 11 on its bottom surface. A threaded rod 12 is inserted into a threaded hole opened inside one of the lower connecting plates 11. The threaded rod 12 and the lower connecting plate 11 are threadedly connected. One end of the threaded rod 12 is rotatably connected to one side of the processing table 1 through a bearing 13.

[0030] In this implementation scheme: the threaded transmission between the threaded rod 12 and the lower connecting plate 11 is used to transform the worker's rotation operation into the smooth linear movement of the U-shaped frame 9, so that the spacing adjustment can be achieved without complex power components, reducing the cost of the device; at the same time, the setting of the bearing 13 reduces the frictional resistance when the threaded rod 12 rotates, making the adjustment operation more effortless and improving the ease of use.

[0031] Furthermore:

[0032] In an optional embodiment, U-shaped blocks 17 are respectively fitted on the surfaces of the two U-shaped frames 9. The U-shaped blocks 17 are fixedly connected to the upper surface of the processing table 1, and the U-shaped blocks 17 and the U-shaped frames 9 are slidably connected.

[0033] In this implementation scheme: the U-shaped card block 17 forms a wrapping guide for the U-shaped frame 9, which can limit the displacement of the U-shaped frame 9 in the vertical direction, prevent the U-shaped frame 9 from tilting upward due to the pressure of the mesh cloth conveying, and ensure that the U-shaped frame 9 drives the limiting plate 1 7 and the limiting plate 2 10 to always move in contact with the upper surface of the processing table 1, and ensure effective contact between the limiting components and the mesh cloth.

[0034] Furthermore:

[0035] In an optional embodiment, inner slide plates 15 are respectively inserted into the inner slide grooves 16 opened on the bottom surfaces of the two limiting plates 7. A spring 14 is fixedly connected between the inner slide plates 15 and the limiting plates 7. The inner slide plates 15 and the limiting plates 7 are slidably connected, and the bottom surface of the inner slide plates 15 is in contact with the upper surface of the processing table 1.

[0036] In this implementation scheme: Under the action of the elastic potential energy of the spring 14, the inner slide plate 15 always fits tightly against the surface of the processing table 1, which can fill the gap between the limiting plate 7 and the processing table 1, and prevent the fiberglass mesh cloth from slipping into the gap during the conveying process, causing wrinkles or damage. At the same time, the inner slide plate 15 can move synchronously with the limiting plate 7 to ensure that the gap filling effect is continuous and effective.

[0037] Furthermore:

[0038] In an optional embodiment, the corners of adjacent sides of the two inner sliding plates 15 are both arc-shaped, and the internal structures of the first limiting plate 7 and the second limiting plate 10 are the same.

[0039] In this implementation scheme: the rounded corners can prevent the inner sliding plate 15 from scratching the edge of the fiberglass mesh. At the same time, when the mesh is slightly misaligned, the rounded surface can form a gentle guiding force on the mesh to help correct the misalignment direction. The limiting plate 1 7 and the limiting plate 2 10 have the same structure, ensuring that the front and rear ends of the mesh conveying path on the processing table 1 can achieve the effect of anti-scratching and auxiliary correction, thereby improving the overall anti-misalignment reliability.

[0040] Furthermore:

[0041] In an optional embodiment, one end of the U-shaped frame 9 is inserted into a groove opened on the surface of the U-shaped plate 2, the U-shaped frame 9 and the U-shaped plate 2 are slidably connected, and the surface of the U-shaped frame 9 is inlaid with scale lines.

[0042] In this implementation plan: the sliding groove of the U-shaped frame 9 and the U-shaped plate 2 further enhances the guiding stability of the movement of the U-shaped frame 9 and prevents it from shaking during long-term use; the scale lines on the surface can intuitively show the distance between the two U-shaped frames 9, and the staff can quickly adjust to the appropriate distance according to the marked width of the fiberglass mesh without additional measuring tools, which greatly shortens the adjustment time and improves the efficiency of production preparation.

[0043] Working Principle: Fiberglass mesh is laid on the surface of processing table 1 by a take-up reel and an unwinding reel. The unwinding reel is driven by an unwinding shaft, a fixing sleeve, and an unwinding motor. During use, the rolled fiberglass mesh is first fixed to the unwinding shaft using the fastening bolts of the fixing sleeve, ensuring the roll rotates synchronously with the unwinding shaft. After startup, the unwinding motor drives the unwinding shaft to rotate at a uniform speed, gradually releasing the mesh from the roll. Simultaneously, the motor speed is controlled to prevent excessively fast unwinding, which could cause mesh accumulation, or excessively slow unwinding, which could cause a sudden increase in tension. The take-up reel is driven by a take-up shaft, a fixing sleeve, and a take-up motor. A take-up roller is fixed to the take-up shaft by the fixing sleeve. During operation, the take-up motor drives the take-up shaft to rotate, causing the mesh to gradually wind around the take-up roller. The mesh fabric is formed into a regular roll. The speed of the winding motor and the speed of the unwinding motor are coordinated and controlled by the controller to ensure that the winding speed and the unwinding speed are matched. This avoids the mesh fabric from loosening or breaking due to speed difference. At the same time, the fixed sleeve adapts to winding rollers of different sizes to meet the roll storage requirements of subsequent processing. The unwinding speed of the unwinding roller and the winding speed of the winding roller are adjusted in conjunction with the controller. Combined with the real-time tension value detected by the tension sensor, the motor speed is dynamically adjusted. When the tension is too high, the controller can appropriately reduce the winding speed or increase the unwinding speed. When the tension is too low, it is adjusted in the opposite direction. Ultimately, the mesh fabric is kept stably transported throughout the entire process of "unwinding, tension adjustment, and winding", providing a power foundation for accurate laying.

[0044] The take-up and unwinding rollers can be placed below both ends of the processing table 1. Under the action of the arc-shaped chamfers on both sides of the processing table 1, the fiberglass mesh cloth is laid on the processing table 1 and conveyed in contact with the surface of the processing table 1. The conveying of the fiberglass mesh cloth by the take-up and unwinding rollers is common to those skilled in the art and belongs to the prior art in this field, so it will not be described in detail here.

[0045] The fiberglass mesh is laid on the surface of the processing table 1, passing between the two limiting plates 7 and the two limiting plates 10. The workers can then perform processing procedures on the fiberglass mesh between the two limiting plates 7 and the two limiting plates 10.

[0046] When it is necessary to adjust the distance between the two limiting plates 7 according to the width of the fiberglass mesh, rotate the threaded rod 12. The rotation of the threaded rod 12 can drive the U-shaped frame 9 to slide inside the U-shaped block 17 under the action of the thread. The movement of the U-shaped frame 9 drives the limiting plates 7 and 10 to move synchronously. The movement of the limiting plates 7 drives the toothed rod 6 to move through the connecting block 8. The movement of the toothed rod 6 drives the gear 5 to rotate, thereby making the two toothed rods 6 move synchronously. This allows the two limiting plates 7 to move synchronously in opposite directions. As the limiting plates 7 move, the distance between the two limiting plates 7 can be adapted to the width of the fiberglass mesh. By observing the scale lines on the surface of the U-shaped frame 9 and combining them with the width marked on the fiberglass mesh, the distance between the two limiting plates 7 can be quickly adjusted, improving the convenience of the device during use. Furthermore, the movement of the limiting plates 7 can make the limiting plates 10 move synchronously, avoiding the problem of the fiberglass mesh between the two limiting plates 7 and 10 shifting.

[0047] Since the internal structures of limiting plate 7 and limiting plate 10 are the same, and the internal parts of limiting plate 7 and limiting plate 10 are respectively equipped with spring 14 and inner sliding plate 15, the inner sliding plate 15 can be made to fit against the upper surface of the processing table 1 under the action of the elastic potential energy of spring 14. When limiting plate 7 and limiting plate 2 move, the inner sliding plate 15 can slide against the surface of the processing table 1, thereby avoiding the problem of the fiberglass mesh sliding between the inner sliding plate 15 and the processing table 1 during the laying process. At this time, the edge of the fiberglass mesh is located between limiting plate 7 and processing table 1, and between limiting plate 2 and processing table 1. With the rounded corners of the adjacent sides of the two inner sliding plates 15, the fiberglass mesh can be easily guided and corrected to ensure that the mesh is aligned with the processing area of ​​the subsequent coating equipment, thereby improving the processing accuracy of the fiberglass mesh.
