Description

Technical Field

[0001] This invention relates to the field of cutting technology, and in particular to a fiber-reinforced mesh cutting platform. Background Technology

[0002] Fiber-reinforced mesh, due to its high tensile strength, good corrosion resistance, and excellent bonding performance with concrete, has been widely used in engineering fields such as bridge reinforcement, tunnel lining, and rail transit. Fiber-reinforced mesh typically consists of multiple perpendicularly intersecting first reinforcing bars (longitudinal bars) and second reinforcing bars (transverse bars). After preparation, it needs to be cut into mesh products of specified sizes according to construction requirements.

[0003] However, existing fiber-reinforced mesh cutting technologies still have many shortcomings in practical applications. Firstly, there is a lack of effective positioning and detection mechanisms during fiber-reinforced mesh cutting. Since the mesh is composed of crisscrossing ribs, if the cutting position happens to align with a longitudinal rib during the cutting process, it will not only damage the longitudinal rib and affect the overall structural strength of the mesh, but may also damage the cutting tool. Existing cutting equipment mostly relies on manual visual judgment to determine the cutting position, making it difficult to achieve automated and precise cutting. This results in low efficiency and difficulty in guaranteeing cutting accuracy.

[0004] Secondly, fiber-reinforced materials are inherently brittle and prone to bursting. When subjected to stress, fiber-reinforced fibers, such as carbon fiber reinforcing bars, explode, and the fiber bundles on the same cross-section are not subjected to uniform stress simultaneously. This makes them highly susceptible to defects such as fiber delamination, cracking, or fraying at the cut edge. Existing cutting equipment lacks effective reinforcement measures for the cut area, resulting in poor quality of the cut mesh ends and affecting subsequent use. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a fiber-reinforced mesh cutting platform that enables rapid positioning and stable cutting.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fiber-reinforced mesh cutting platform, comprising a workbench for supporting the mesh; a cutting unit disposed above the workbench; and a detection unit disposed within the workbench; the detection unit includes a movable detection rod for detecting the position of the mesh, and the detection rod is arranged parallel to the cutting unit; the mesh is composed of multiple mutually perpendicular and intersecting first and second reinforcing bars, with the first reinforcing bars located above the second reinforcing bars; the highest point of the detection rod is higher than the lower surface of the first reinforcing bars; the cutting unit is configured to perform a cutting action when the detection rod is not pressed down by the first reinforcing bars.

[0007] In the above scheme, preferably, the detection unit further includes a sliding sleeve, the detection rod is connected in the sliding sleeve by a first spring, and the top of the detection rod is an arc-shaped surface.

[0008] In the above scheme, preferably, a plurality of symmetrically arranged first clamping units and second clamping units are provided to align the second rib. Each first clamping unit and second unit includes a base, a first clamping rod and a second clamping rod. The first clamping rod and the second clamping rod are slidably connected in the base. A first mold and a second mold are provided at the placement part of the first clamping rod and the second clamping rod. The first mold and the second mold move towards each other to clamp the second rib.

[0009] In the above scheme, preferably, the first clamping unit and the second clamping unit are respectively located on both sides of the cutting unit, and the first mold and the second mold are connected to an external container through pipelines. When the first mold and the second mold are closed, reinforcing resin is injected into them to achieve explosion protection for the second rib.

[0010] In the above scheme, preferably, the base is connected to the disassembly blocks on both sides by a slide rod, and the disassembly block is provided with a first slide rail perpendicular to the platform. The first slide rail is used to guide the first clamping unit and the second clamping unit to rise or fall.

[0011] In the above scheme, preferably, the second clamping unit further includes a clamping part located below the first mold and the second mold. The clamping part is provided with a flexible friction block. When the second clamping unit rises and the second rib is in the flexible friction block, the second rib is temporarily fixed in the clamping part.

[0012] In the above scheme, preferably, the disassembly block of the second clamping unit is provided with a second slide rail that is perpendicular to the first slide rail. After the second clamping unit moves to the second slide rail, the first slide rod can be prepared to slide towards the second slide rail to drag the mesh fabric forward.

[0013] In the above scheme, preferably, the first slide rod includes an L-shaped mounting plate, the first slide rod is detachable from the mounting plate, and a second spring is provided on the side of the first slide rod parallel to the mounting plate. When the first slide rod moves to the highest point of the first slide rail, the first slide rod moves towards the second slide rail against the first spring.

[0014] In the above scheme, preferably, the disassembly block is provided with a lifting component to control the first slide rod, and a driving component is provided in the second slide rail. When the lifting component drives the first slide rod to the highest point of the first slide rail, the driving component is activated to control the first slide rod to move there.

[0015] In the above scheme, preferably, it also includes a trimming unit, which includes a blade for trimming excess mesh.

[0016] The beneficial effects of this invention are as follows: By setting a movable detection rod arranged parallel to the cutting unit, with the highest point of the detection rod higher than the lower surface of the first rib, the cutting action is only performed when the detection rod is not pressed down by the first rib, effectively avoiding the problem of the cutting unit accidentally cutting the first rib, and ensuring the integrity of the mesh structure and the cutting accuracy. The top of the detection rod adopts an arc-shaped surface design, which, together with the elastic reset of the first spring, can smoothly guide the first rib over the detection rod, reducing jamming and friction damage.

[0017] The cutting unit is symmetrically equipped with a first clamping unit and a second clamping unit on both sides. After the second rib is clamped by the first mold and the second mold, reinforcing resin is injected to coat the section of the second rib to be cut. After curing, the resin significantly improves the tensile strength and explosion-proof performance of the second rib. During cutting, the ends of the rib are reinforced with resin and will not burst, effectively avoiding defects such as fiber delamination, cracking, or fraying, thus achieving high-quality explosion-proof cutting.

[0025] Figure 8 This is a schematic diagram of the detection unit of the present invention. Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-8A fiber-reinforced mesh cutting platform is applicable to a mesh 5 consisting of a first rib 6 and a second rib 7 that are perpendicularly connected to each other, wherein the first rib 6 is located above the second rib 7, and the first rib 6 is usually a continuous longitudinal rib, while the second rib 7 is a transversely distributed rib.

[0027] The system includes a workbench 1 for supporting the mesh sheet 5. A cutting unit 2 is positioned above the workbench 1 to cut the mesh sheet 5. A detection unit 3 is also located within the workbench 1. The detection unit 3 includes a movable detection rod 4, which is arranged parallel to the cutting unit 2, meaning its extension direction is aligned with the cutting direction of the cutting element 28 of the cutting unit 2. This allows for accurate sensing of the position of the mesh sheet 5 along the cutting line. The highest point of the detection rod 4 is set above the lower surface of the first rib 6. This means that when the mesh sheet 5 is normally placed on the workbench 1, if a first rib 6 is directly above the detection rod 4, the first rib 6 will press down on the detection rod 4; conversely, if there is no first rib 6 above the detection rod 4, the detection rod 4 will not be pressed down.

[0028] The control logic of the cutting unit 2 is configured to execute the cutting action only when the detection rod 4 is not pressed down by the first rib 6. That is, when the detection rod 4 is in a freely extended state, it indicates that the current cutting position is in the blank area between the two first ribs 6. At this time, the cutting unit 2 is activated to cut the second rib 7 without accidentally cutting the first rib 6, thereby ensuring the accuracy of the cutting and the integrity of the mesh 5 structure.

[0029] Furthermore, the specific structure of the detection unit 3 includes a sliding sleeve 8, and the detection rod 4 is connected to the sliding sleeve 8 via a first spring 9. The detection rod 4 can slide up and down along the sliding sleeve 8. The first spring 9 is a compression spring, which normally pushes the detection rod 4 upward to its highest position. The top of the detection rod 4 is set as an arc-shaped surface, such as a hemispherical or round-headed shape. This way, when the first rib 6 moves with the mesh 5 and passes over the detection rod 4, even if the top of the detection rod 4 contacts the lower surface of the first rib 6, the arc-shaped surface can smoothly guide the first rib 6 over the detection rod 4, reducing jamming and friction damage.

[0030] To stably clamp the second rib 7 during the cutting process and prevent it from bursting (i.e., the fiber bundles breaking apart) under the cutting force, the platform is symmetrically equipped with a first clamping unit 10 and a second clamping unit 11 on both sides of the cutting unit 2. These units are located at the feed inlet 30 and the discharge outlet 31 of the cutting unit 2, respectively, and are aligned with the second rib 7. Each clamping unit includes a base 12, a first clamping rod 13, and a second clamping rod 14. The first clamping rod 13 and the second clamping rod 14 are slidably connected to the base 12, and a first mold 15 and a second mold 16 are fixedly mounted at their opposite placement portions. The placement portions are located at the upper ends of the clamping rods. When the first mold 15 and the second mold 16 move towards each other, they approach from both sides and finally clamp the second rib 7. After clamping, the cavities of the first mold 15 and the second mold 16 together form a sealed space surrounding the area to be cut of the second rib 7.

[0031] Preferably, the first mold 15 and the second mold 16 are connected to an external container via pipes, and the external container stores reinforcing resin, such as epoxy resin or vinyl ester resin. After the first mold 15 and the second mold 16 clamp the second rib 7, the reinforcing resin is injected into the mold through the pipes. The resin quickly fills the mold cavity and covers the section of the second rib 7 to be cut. After the resin cures, the tensile strength and explosion-proof performance of the second rib 7 are significantly improved. The first clamping unit 10 and the second clamping unit 11 provide space for the cutting path of the cutting unit 2, ensuring that the reinforced ends do not burst during cutting. This effectively avoids defects such as fiber delamination, cracking, or fraying at the ends of the second rib 7, achieving explosion-proof cutting.

[0032] The bases 12 of the first clamping unit 10 and the second clamping unit 11 are respectively connected to the disassembly blocks 18 on both sides via slide rods 17. The disassembly blocks 18 are fixedly installed on the side of the worktable 1. Each disassembly block 18 has a first slide rail 19 perpendicular to the surface of the worktable 1. The slide rod 17 can slide up and down along the first slide rail 19, thereby driving the entire clamping unit to rise or fall. By adjusting the height of the clamping unit, it is ensured that the first mold 15 and the second mold 16 can be accurately aligned with the height position of the second rib 7.

[0033] The second clamping unit 11 is further provided with a clamping part 21, which is located below the first mold 15 and the second mold 16. The clamping part 21 is provided with a flexible friction block 22, which is a rubber or polyurethane block. When the second clamping unit 11 rises as a whole until the second rib 7 is between the flexible friction blocks 22, the flexible friction blocks 22 use elastic deformation to hug the second rib 7, temporarily fixing the second rib 7 in the clamping part 21.

[0034] Furthermore, a second slide 20 is provided on the disassembly block 18 corresponding to the second clamping unit 11, perpendicular to the first slide 19. The second slide 20 intersects the first slide 19 and extends horizontally. The second clamping unit 11 can rise to its highest position along the first slide 19 and then move horizontally along the second slide 20. When the second clamping unit 11 moves to the second slide 20, the slide rod 17 rotates from the first slide 19 into the second slide 20, and the entire clamping unit slides along the second slide 20, thereby dragging the mesh 5 forward to achieve short-distance feeding. This ensures that the second rib 7 is not aligned with the cutting blade.

[0035] In its specific implementation, the slide rod 17 of the second clamping unit 11 includes an L-shaped mounting plate, and the slide rod 17 body is detachably mounted on the mounting plate. A second spring 24 is provided on the side of the slide rod 17 parallel to the mounting plate, providing a horizontal elastic force. When the slide rod 17 rises to its highest position along the first slide rail 19, the end of the slide rod 17 is precisely aligned with the entrance of the second slide rail 20. At this time, the slide rod 17 overcomes the elastic force of the second spring 24 and moves into the second slide rail 20 under the action of the driving member 26, thereby completing the reversal. If the slide rod 17 does not rise to its highest point, the second spring 24 maintains the position of the slide rod 17 within the first slide rail 19 to prevent accidental lateral movement.

[0036] The disassembly block 18 is equipped with a lifting component 25 that controls the raising and lowering of the slide rod 17. The lifting component 25 can be an electric push rod, the output end of which is connected to the mounting plate. A driving component 26, which is an electromagnet, is provided in the second slide rail 20. When the lifting component 25 drives the slide rod 17 to the highest point of the first slide rail 19, the driving component 26 is activated. Under the action of magnetic force, it controls the slide rod 17 to move horizontally along the second slide rail 20, driving the second clamping unit 11 and the clamped mesh 5 forward together, realizing precise step feeding.

[0037] The sliding sleeve 8 is equipped with a switch for controlling the drive component 26. When the switch is pressed by the detection rod 4, the drive component 26 is activated.

[0038] Since the dimensions of the displaced mesh 5 will change after cutting, a trimming unit 27 is also provided on the platform. The trimming unit 27 includes a trimming element 29, which is arranged parallel to the cutting element 28. The distance between the trimming element 29 and the cutting element 28 is the actual distance for cutting the mesh 5. Therefore, when the moving mesh 5 avoids the first rib 6 from corresponding with the cutting element 28, the trimming unit 27 moves along the edge of the mesh 5 to remove excess ribs or burrs, ensuring the width consistency and edge smoothness of the finished mesh 5.

[0039] Principle: First step: When the detection rod 4 does not detect the first rib 6, the cutting is permitted. When the mesh 5 moves forward to the test position in the transport device, and there is no first rib 6 directly above the current cutting position, the detection rod 4 is kept at the highest extended position under the action of the compression spring. The top arc surface is higher than the lower surface of the first rib 6, but there is no external force pressing down.

[0040] The switch inside the sliding sleeve 8 was not triggered, therefore the cutting platform control system determined that the cutting area was safe. After the lifting member 25 raised the first clamping unit 10 and the second clamping unit 11 to a suitable height, the first clamping unit 10 and the second clamping unit 11 closed the mold, clamped the two ends of the second rib 7 to be cut, and injected reinforcing resin. After curing, the explosion resistance was improved. The further cutting unit 2 was activated, and the cutting member 28 precisely cut the second rib 7 along the direction of the worktable 1. Since there was no obstruction from the first rib 6, the cutting only acted on the transversely distributed ribs, and the longitudinal main ribs were completely preserved. After the cutting was completed, the second clamping unit 11 drove the mesh sheet 5 to step feed, entering the next detection cycle.

[0041] Part Two: The detection rod 4 detects the first rib 6 and cannot directly cut into the locked state. The first rib 6 is located directly above the current cutting position. The lower surface of the rib contacts and presses down on the arc-shaped top of the detection rod 4, causing the detection rod 4 to retract downwards into the sliding sleeve 8 against the spring force. As the detection rod 4 is pressed down, the switch inside the sliding sleeve 8 is triggered, and the control system issues a locking command. First, the lifting component 25 is activated, causing the second clamping unit 11 to rise to a higher height than before, temporarily locking the flexible friction block 22 and the second rib 7. When the sliding rod 17 moves to the end of the first slide rail 19, it is activated by the driving component 26. After the sliding rod 17 moves to one end of the second slide rail 20, under the action of the driving component 26, the sliding rod 17 moves towards the second slide rail 20, that is, the mesh 5 advances a small distance until the detection rod 4 extends again, that is, moves to the blank area between the two first ribs 6. After the switch is not triggered, the sliding rod 17 and the second clamping unit 11 reset, and the process returns to the first part.

[0042] The first clamping unit 10 and the second clamping unit 11's first mold 15 and second mold 16 clamp the second rib 7 together, inject reinforcing resin, and then the cutting edge completes the cut in the resin-reinforced area. At the same time, the trimming unit 27 works synchronously. Since the distance between the trimming unit 27 and the cutting unit 2 is fixed, after the trimming unit 27 is started, it cuts off the excess second rib 7 to complete the accurate cut.
