Description

Technical Field

[0001] This utility model relates to the field of composite wall panel cutting and positioning technology, and specifically discloses a composite wall panel cutting and positioning device. Background Technology

[0002] Composite wall panels, as a new type of interior partition wall, are widely used due to their advantages such as lightweight, environmental friendliness, and convenient construction. On construction sites, composite wall panels often need to be cut and processed according to installation conditions; therefore, the stability, safety, and functionality of the positioning and clamping devices during the cutting process are particularly important.

[0003] Currently, there are some positioning devices for cutting composite wall panels, such as a positioning device for cutting prefabricated composite wall panels with authorization announcement number CN 210452927U. It uses a motor to drive a wire rod to move a positioning block along a slide rail to achieve positioning of wall panels of different sizes, and uses a sliding structure to push the wall panel to move, avoiding the safety hazards caused by manual direct pushing of materials.

[0004] However, this existing technology still has the following drawbacks:

[0005] The positioning method is simple and the clamping force is insufficient. This device only uses a pair of positioning blocks to laterally limit the wall panel and lacks a pressing mechanism from top to bottom. For composite wall panels that are thin or have uneven surfaces, displacement or vibration is likely to occur during the cutting process, affecting the cutting accuracy and safety.

[0006] Lacking dust removal capabilities and operating in a poor environment, this device lacks any dust removal structure. Dust generated during the cutting process cannot be collected and treated in a timely manner, which not only pollutes the working environment but may also harm the health of operators, as well as affect the lifespan of the equipment and the quality of the cut.

[0007] Therefore, there is an urgent need for a composite wall panel cutting and positioning device with multi-directional clamping function and follow-up dust removal capability to solve the above problems. Utility Model Content

[0008] This utility model proposes a composite wall panel cutting and positioning device, which achieves high quality, environmentally friendly, safe and widely adaptable composite wall panel cutting through multi-directional precise positioning and clamping, follow-up efficient dust removal and automatic control. At the same time, the structure is stable and durable, and it completely solves the defects of the existing technology.

[0009] This utility model is implemented as follows: a composite wall panel cutting and positioning device includes a base, a U-shaped frame fixedly installed on the base, and a controller and a cutting mechanism set on the U-shaped frame. Several rollers for conveying composite wall panels are installed in parallel and rotatably inside the U-shaped frame. It also includes a follow-up dust removal mechanism and at least two sets of positioning and clamping mechanisms.

[0010] The follow-up dust removal mechanism includes a dust suction hood, a hose, and a dust collector. The two ends of the hose are respectively connected to the input ends of the dust suction hood and the dust collector. The dust suction hood is fixedly mounted on the moving part of the cutting mechanism via a connecting bracket and moves synchronously with it.

[0011] The positioning and clamping mechanisms are symmetrically arranged on both sides inside the U-shaped frame. Each positioning and clamping mechanism includes a slider, an inverted L-shaped positioning plate, a pressure plate, a lifting drive component, and a bidirectional lead screw. The slider is slidably disposed below the space between two adjacent rollers. The vertical part of the inverted L-shaped positioning plate passes through the gap between two adjacent rollers and is fixedly connected to the slider. The pressure plate is located below the horizontal part of the inverted L-shaped positioning plate. The lifting drive component is fixedly installed at the upper end of the horizontal part of the inverted L-shaped positioning plate, and its output end is connected to the pressure plate to drive it to press or release the workpiece. The bidirectional lead screw is arranged parallel to the rollers, and its two ends are rotatably connected to the U-shaped frame. The slider is threadedly connected to the bidirectional lead screw.

[0012] One side of the U-shaped frame is provided with a drive cavity, and the drive cavity is provided with a drive motor and a worm gear mechanism that synchronously drives all bidirectional lead screws to rotate.

[0013] As a preferred embodiment of the composite wall panel cutting and positioning device of this utility model, the worm gear mechanism includes a worm driven by a drive motor and a number of worm wheels equal to the number of the bidirectional lead screw. Each worm wheel meshes with the worm and is coaxially fixedly sleeved on the end of a bidirectional lead screw.

[0014] As a preferred embodiment of the composite wall panel cutting and positioning device of this utility model, the positioning and clamping mechanism further includes at least one guide rod parallel to the bidirectional lead screw, the two ends of the guide rod being fixedly connected to the U-shaped frame, and the slider being slidably connected to the guide rod.

[0015] As a preferred embodiment of the composite wall panel cutting and positioning device of this utility model, the cutting mechanism includes a gantry frame slidably mounted on the U-shaped frame, a slide block slidably mounted on the crossbeam of the gantry frame, a cutting motor fixedly mounted on the slide block, and a cutting head driven by the cutting motor and located above the roller; the connecting bracket is fixed on the slide block, and the dust suction port of the dust suction hood faces downwards from the saw blade of the cutting head; the dust collector is located on the gantry frame.

[0016] As a preferred embodiment of the composite wall panel cutting and positioning device of this utility model, the lifting drive component is an electric push rod or a cylinder.

[0017] As a preferred embodiment of the composite wall panel cutting and positioning device of this utility model, rubber pads are adhered to the inner side of the vertical part of the inverted L-shaped positioning plate and the bottom of the pressure plate.

[0018] In a preferred embodiment of the composite wall panel cutting and positioning device of this utility model, a pressure sensor is embedded inside the rubber pad, and the controller is electrically connected to the pressure sensor, the drive motor and the lifting drive component, for receiving pressure signals and controlling the start and stop of the drive motor and the movement of the lifting drive component.

[0019] The beneficial effects of this utility model are:

[0020] 1. By using multiple sets of symmetrical positioning and clamping mechanisms, lateral synchronous positioning and vertical clamping are achieved. With the help of guide rods to limit slider displacement and rubber pads to increase friction and buffer vibration, displacement or vibration during wall panel cutting is effectively avoided. This solves the problems of single positioning and insufficient clamping force in existing devices, and significantly improves cutting accuracy.

[0021] 2. The dust hood moves synchronously with the cutting head, collecting dust at the cutting point in real time. The dust is then centrally processed by the dust collector, which solves the problem of the lack of dust removal function in existing devices. This avoids dust pollution of the environment, harm to the health of operators and affect the life of equipment, while also reducing the interference of dust on cutting quality.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0029] Please see Figure 1-4 A composite wall panel cutting and positioning device includes a base 1, a U-shaped frame 2 fixedly installed on the base 1, a controller 3 and a cutting mechanism set on the U-shaped frame 2, and a plurality of rollers 4 for conveying composite wall panels are installed in parallel and rotatably inside the U-shaped frame 2. It also includes a follow-up dust removal mechanism and at least two sets of positioning and clamping mechanisms.

[0030] The follow-up dust removal mechanism includes a dust suction hood 5, a hose 6, and a dust collector 7. Both ends of the hose 6 are connected to the input ends of the dust suction hood 5 and the dust collector 7, respectively. The dust suction hood 5 is fixedly mounted on the moving part of the cutting mechanism via a connecting bracket 8 and moves synchronously with it.

[0031] The positioning and clamping mechanisms are symmetrically arranged on both sides inside the U-shaped frame 2. Each positioning and clamping mechanism includes a slider 9, an inverted L-shaped positioning plate 10, a pressure plate 11, a lifting drive component 12, and a bidirectional lead screw 13. The slider 9 is slidably disposed below the space between two adjacent rollers 4. The vertical part of the inverted L-shaped positioning plate 10 passes through the gap between two adjacent rollers 4 and is fixedly connected to the slider 9. The pressure plate 11 is located below the horizontal part of the inverted L-shaped positioning plate 10. The lifting drive component 12 is fixedly installed on the upper end of the horizontal part of the inverted L-shaped positioning plate 10, and its output end is connected to the pressure plate 11 to drive it to press or release the workpiece. The bidirectional lead screw 13 is arranged parallel to the rollers 4, and its two ends are rotatably connected to the U-shaped frame 2. The slider 9 is threadedly connected to the bidirectional lead screw 13.

[0032] A drive chamber 14 is provided on one side of the U-shaped frame 2. The drive chamber 14 contains a drive motor 15 and a worm gear mechanism that synchronously drives all bidirectional lead screws 13 to rotate.

[0033] In this embodiment: When the composite wall panel cutting and positioning device is working, the operator starts the equipment through the controller 3. First, the composite wall panel to be cut is placed on the roller 4. The drive motor 15 drives all the worm gears 17 to rotate synchronously through the worm gear 16, which in turn drives all the bidirectional lead screws 13 to rotate, so that the sliders 9 on both sides move synchronously towards each other along the guide rod 18, driving the inverted L-shaped positioning plate 10 to clamp the workpiece from both sides for centering and positioning. Then, the lifting drive component 12 moves to push the pressure plate 11 downward, which together with the horizontal part of the inverted L-shaped positioning plate 10 presses and fixes the workpiece from the top and bottom. After positioning is completed, the cutting mechanism is started. The cutting motor 21 drives the cutting head 22 to cut the workpiece. At the same time, the dust suction hood 5 fixed on the cutting mechanism slide 20 moves synchronously with the cutting head 22, always aligning with the dust-generating point of cutting. The dust generated by cutting is sucked into the dust collector 7 through the hose 6 to collect it, realizing synchronous dust removal. After cutting is completed, each mechanism is reset, the workpiece is released, and the roller 4 transports it out of the processing area, completing one processing operation.

[0034] As a technical optimization of this utility model, the worm gear mechanism includes a worm 16 driven by a drive motor 15, and a number of worm wheels 17 equal to the number of bidirectional lead screws 13. Each worm wheel 17 meshes with the worm 16, and each worm wheel 17 is coaxially fixedly sleeved on the end of a bidirectional lead screw 13.

[0035] In this embodiment, a single worm gear 16 synchronously drives all worm wheels 17, ensuring that all bidirectional lead screws 13 rotate synchronously, accurately, and smoothly. This enables the positioning and clamping mechanisms on both sides to move synchronously and symmetrically, achieving centering and positioning of the workpiece and avoiding jamming or asynchrony problems that may occur with unilateral drive.

[0036] As a technical optimization of this utility model, the positioning and clamping mechanism also includes at least one guide rod 18 parallel to the bidirectional lead screw 13. The two ends of the guide rod 18 are fixedly connected to the U-shaped frame 2, and the slider 9 is slidably connected to the guide rod 18.

[0037] In this embodiment, a guide rod 18 structure is added to enhance the stability and rigidity of the slider 9 during movement, prevent it from rotating or shaking due to force, and ensure positioning accuracy.

[0038] As a technical optimization of this utility model, the cutting mechanism includes a gantry frame 19 slidably mounted on the U-shaped frame 2, a slide block 20 slidably mounted on the crossbeam of the gantry frame 19, a cutting motor 21 fixedly mounted on the slide block 20, and a cutting head 22 driven by the cutting motor 21 and located above the roller 4; the connecting bracket 8 is fixed on the slide block 20, and the dust suction port of the dust suction hood 5 faces the lower part of the saw blade of the cutting head 22; the dust collector 7 is provided on the gantry frame 19.

[0039] In this embodiment: the cutting mechanism and the dust removal mechanism move synchronously, ensuring that the dust hood 5 is always accurately aligned with the cutting point to collect cutting dust to the maximum extent. At the same time, the movement logic of the cutting mechanism is clarified to improve cutting flexibility and dust removal efficiency.

[0040] It should be noted that the horizontal beam of the gantry frame 19 is slidably connected to the vertical parts on both sides. When the horizontal beam of the gantry frame 19 slides up and down, the height of the cutting mechanism can be adjusted, making it easy to cut composite wall panels of different thicknesses. The horizontal beam is driven by a linear actuator (the linear actuator is an electric push rod or a cylinder).

[0041] As a technical optimization of this utility model, the lifting drive component 12 is an electric push rod or a cylinder.

[0042] In this embodiment, a stable and controllable power source is provided for the lifting and lowering action of the pressure plate 11, ensuring that the pressure plate 11 can reliably press or release the workpiece, adapting to composite wall panels of different thicknesses, and offering two types to improve the versatility and practicality of the equipment.

[0043] As a technical optimization of this utility model, rubber pads 23 are adhered to the inner side of the vertical part of the inverted L-shaped positioning plate 10 and the bottom of the pressure plate 11.

[0044] In this embodiment: the rubber pad 23 increases friction to prevent slippage during clamping; and protects the surface of the composite wall panel from pressure damage or scratches.

[0045] As a technical optimization of this utility model, a pressure sensor 24 is embedded inside the rubber pad 23. The controller 3 is electrically connected to the pressure sensor 24, the drive motor 15 and the lifting drive component 12, and is used to receive pressure signals and control the start and stop of the drive motor 15 and the movement of the lifting drive component 12.

[0046] In this embodiment, real-time monitoring and automated control of clamping force are realized. When the pressure reaches the set value, the drive motor 15 and the lifting drive component 12 are automatically stopped, which ensures sufficient clamping force and avoids damage to the workpiece due to overpressure, thus realizing intelligent operation.

[0047] Working principle and usage process of this utility model:

[0048] The operator places the composite wall panel to be cut onto the roller 4 inside the U-shaped frame 2. The rotation of the roller 4 transports the wall panel to the preset cutting position, and then stops the roller 4. The operator starts the drive motor 15 in the drive chamber 14 through the controller 3. The drive motor 15 drives the worm gear 16 to rotate. The worm gear 16 simultaneously engages with the worm wheels 17 at the ends of all the bidirectional lead screws 13, causing multiple bidirectional lead screws 13 to rotate synchronously. When the bidirectional lead screws 13 rotate, they drive the sliders 9 on both sides to move synchronously along the guide rod 18 towards the wall panel. The sliders 9 drive the inverted L-shaped positioning plate 10. The vertical part is close to both sides of the wall panel; when the rubber pad 23 on the inner side of the vertical part of the inverted L-shaped positioning plate 10 contacts the wall panel and generates pressure, the pressure sensor 24 inside the rubber pad 23 transmits the pressure signal to the controller 3. When the pressure reaches the preset lateral positioning value, the controller 3 controls the drive motor 15 to stop, completing the lateral positioning of the wall panel; after the drive motor 15 stops, the controller 3 automatically starts the lifting drive component 12 in the positioning clamping mechanism. The lifting drive component 12 drives the pressure plate 11 to move downward until the rubber pad 23 at the bottom of the pressure plate 11 contacts the upper surface of the wall panel and... Pressure is generated; the pressure sensor 24 at the bottom of the pressure plate 11 transmits the pressure signal to the controller 3. When the pressure reaches the preset vertical clamping value, the controller 3 controls the lifting drive component 12 to stop, realizing the vertical clamping of the wall panel and preventing displacement or vibration during cutting; the operator starts the cutting mechanism through the controller 3, the cutting motor 21 drives the cutting head 22 to rotate, and at the same time controls the gantry frame 19 to slide along the U-shaped frame 2 and the slide block 20 to slide along the crossbeam of the gantry frame 19, so that the cutting head 22 can accurately cut the wall panel; during the cutting process, the dust collection hood 5 fixed to the slide block 20 moves with the wall panel. The cutting head 22 moves synchronously, and the dust suction port is aligned with the cutting area below the saw blade in real time. The dust generated is sucked into the dust collector 7 through the hose 6 to prevent dust from spreading. After the cutting is completed, the controller 3 first controls the cutting motor 21 to stop, then controls the lifting drive component 12 to drive the pressure plate 11 to reset upwards. Subsequently, it controls the drive motor 15 to rotate in the opposite direction, driving the bidirectional lead screw 13 to rotate in the opposite direction, so that the slider 9 and the inverted L-shaped positioning plate 10 reset to both sides. Finally, the roller 4 is started to transport the cut wall panel to the picking position. The operator removes the wall panel, completing one cutting operation.
