Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool technology, specifically relating to an automatic feeding device for a CNC sawing machine. Background Technology

[0002] CNC sawing machines are widely used in batch cutting of materials such as metal and wood due to their high cutting precision and ease of operation. To improve production efficiency, CNC sawing machines are usually equipped with automatic feeding devices to achieve continuous material conveying and positioning, reducing errors and safety hazards caused by manual intervention. Traditional CNC sawing machine feeding devices mostly use fixed track conveyor structures, and the size and height of their feeding channels are often fixed, making it difficult to adapt to the conveying needs of materials of different specifications. When processing different types of materials, it is necessary to manually adjust the baffle spacing or replace the conveying components, which is cumbersome and time-consuming, seriously affecting the continuity of production. At the same time, during the feeding process, debris, burrs, or waste generated from cutting on the surface of the material can easily fall into the conveying device and... If these impurities are not cleaned in time, they will enter the transmission components as the equipment runs, leading to accelerated wear of components, reduced operating accuracy, and even equipment jamming, increasing maintenance costs and downtime. Existing cleaning methods mostly rely on manual periodic cleaning, which is not only labor-intensive but also untimely, making it difficult to meet the high-efficiency operation requirements of automated production lines. In addition, the feeding adjustment and waste cleaning functions of some feeding devices are independent of each other, lacking linkage design, resulting in complex equipment structure, large space occupation, and poor coordination between adjustment and cleaning actions, further restricting the improvement of feeding efficiency and processing accuracy.

[0003] Therefore, the problem to be solved by this utility model is to provide an automatic feeding device for CNC sawing machines that can adapt to materials of different specifications and realize the linkage between feeding adjustment and waste cleaning. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an automatic feeding device for CNC sawing machines that can adapt to materials of different specifications and realize the linkage between feeding adjustment and waste cleaning.

[0005] To solve the above-mentioned technical problems, the present invention provides an automatic feeding device for a CNC sawing machine, comprising an RGV transport vehicle with a feeding adjustment device at the top and a cleaning assembly between the feeding adjustment device and the RGV transport vehicle. The feeding adjustment device includes a conveying frame placed on top of the RGV transport vehicle, with the upper inner side of the conveying frame fixedly connected to the lower outer side of a baffle. The outer wall of the baffle is slidably connected to the adjustment frame, and horizontal plates are fixed to the upper ends of both the front and rear sides of the adjustment frame. The cleaning assembly includes a receiving frame installed between the RGV transport vehicle and the conveying frame. Two sets of scrapers are slidably connected inside the receiving frame. The scrapers have locking interfaces that engage with the edge of the receiving frame. Inclined plates are fixed on both sides of the receiving frame, and a collection box is provided at the end of the inclined plates away from the receiving frame.

[0006] The RGV transport vehicle has clamps on both sides of the recessed area for fixing the conveying frame, and the conveying frame is fitted between the clamps; the bottom of the RGV transport vehicle is provided with a slide rail for it to move, and a saw body for cutting materials is placed on one side of the slide rail.

[0007] Multiple sets of ball bearings are installed on both sides of the baffle. The ball bearings are evenly distributed in the vertical direction on both sides of the baffle, and the ball bearings are rotatably connected to the baffle.

[0008] The bottom of the conveying frame is hollow, and the adjustment frame is equipped with an elastic element that engages with the ball bearings. The elastic element is fixedly connected to the lower side of the inner wall of the adjustment frame.

[0009] Hydraulic tanks are fixed at both ends of the conveying frame. A piston rod is slidably connected inside the hydraulic tank, and the top of the piston rod is fixedly connected to the cross plate.

[0010] The hydraulic tank is connected to a multi-stage telescopic tube on one side. The multi-stage telescopic tube has a folded structure with multiple bends. An abutment plate is fixed to the end of the multi-stage telescopic tube. Connecting blocks are fixed to both ends of the two sets of scrapers. The connecting blocks are fixed to the belt.

[0011] The inner wall of the belt is provided with pulleys on both sides, which are rotatably connected to the receiving frame.

[0012] The upper and lower ends of the belt are fixedly connected to the connecting blocks on the two sets of scrapers, and the abutment plate is fixedly connected to one of the connecting blocks.

[0013] The extension stroke of the multi-stage telescopic tube is adapted to the sliding stroke of the piston rod. When the piston rod is fully pressed into the hydraulic tank, the multi-stage telescopic tube extends to its maximum length, driving the scraper to move to the edge of the receiving frame.

[0014] The inner wall of the receiving frame has gaps on both sides for debris to be removed.

[0015] The main beneficial effects of this utility model are as follows: I. Improve feeding efficiency and adapt to the needs of multiple material specifications The feeding adjustment device achieves flexible adjustment of the conveying space through a combination design of baffle, sliding adjustment frame, ball bearings, and elastic element. The operator can lift the horizontal plate upward to move the adjustment frame along the baffle, so that the elastic element engages with the ball bearings at different positions for limiting. This design breaks the limitation of fixed storage space in traditional feeding devices, and can flexibly expand the stacking space according to the height of the material. More material can be stacked at once, directly improving the single feeding volume and overall feeding efficiency. At the same time, there is no need to frequently replace the conveying parts, adapting to the conveying needs of materials of different specifications, reducing equipment adjustment time, and further ensuring production continuity.

[0016] II. Ensure the safety of material transportation and prevent material loss due to falling. The baffle and adjustment frame in the feeding adjustment device form an "enclosed" protective structure: the baffle is fixed to the top of the conveying frame, and the adjustment frame can slide to enclose the material storage area together with the baffle. During the feeding process of the RGV transport vehicle moving along the slide rail, it can effectively prevent the material from falling due to bumps and inertia, reduce the loss of materials during transportation, and is especially suitable for conveying materials that are easy to fall, such as long strips and irregularly shaped metal profiles, thereby improving the safety and stability of material transportation.

[0017] Third, achieve automated debris removal, reducing labor costs and secondary pollution. Addressing the pain point of manual cleaning of debris residue after material cutting in traditional equipment, the cleaning component achieves automated debris handling through multi-structure collaboration: Real-time chip removal: The bottom of the conveyor frame is hollow, so the metal chips and dust left after the material is cut can fall directly into the receiving frame below through the hollow, without the need for manual sorting in advance, thus achieving chip removal during the conveying process.

[0018] Automatic debris collection: When it is necessary to clean the debris in the receiving frame, the pressing plate drives the piston rod to squeeze the hydraulic tank, so that the hydraulic oil pushes the multi-stage telescopic tube and the abutment plate to move. Then, through the transmission of the connecting block belt and pulley, the two sets of scrapers slide relative to each other in the receiving frame, pushing the debris to both sides.

[0019] Centralized debris collection: The pushed debris slides through the gaps on both sides of the receiving frame onto the inclined plate and finally falls into the collection box. The entire process does not require manual contact with the debris, which avoids secondary pollution caused by manual cleaning, such as debris dust and hand contact pollution, and greatly reduces the labor intensity of workers, improving cleaning efficiency and the cleanliness of the working environment.

Detailed Implementation

[0028] like Figures 1-6 An automatic feeding device for a CNC sawing machine includes a feeding adjustment device 200 at the top of an RGV transport vehicle 100, and a cleaning assembly 300 between the feeding adjustment device 200 and the RGV transport vehicle 100. The feeding adjustment device 200 includes a conveying frame 210 placed on top of the RGV transport vehicle 100. The upper inner side of the conveying frame 210 is fixedly connected to the lower outer side of a baffle 220. The outer wall of the baffle 220 is slidably connected to an adjustment frame 230, and horizontal plates 250 are fixed to the upper ends of both the front and rear sides of the adjustment frame 230. The cleaning assembly 300 includes a receiving frame 310 installed between the RGV transport vehicle 100 and the conveying frame 210, and two sets of scrapers are slidably connected inside the receiving frame 310. The scraper 320 has a locking interface 321 that engages with the edge of the receiving frame 310. Inclined plates 390 are fixed on both sides of the receiving frame 310. A collection box 3910 is provided at the end of the inclined plate 390 away from the receiving frame 310. By integrating the RGV transport vehicle 100, the feeding adjustment device 200, and the cleaning component 300, an integrated automatic feeding system is formed to realize the coordinated operation of material conveying and debris cleaning. The sliding connection design of the adjustment frame 230 and the baffle 220 provides basic structural support for adapting to materials of different specifications. The locking design of the scraper 320 ensures sliding stability. The inclined plate 390 and the collection box 3910 work together to realize the directional collection of debris. The overall structure is compact and functionally complete.

[0029] Preferably, the RGV transport vehicle 100 has clamping plates 101 on both sides of the recessed area for fixing the conveying frame 210, and the conveying frame 210 is fitted between the clamping plates 101; the bottom of the RGV transport vehicle 100 is provided with a slide rail 110 for its movement, and a saw body 120 for cutting materials is placed on one side of the slide rail 110; the clamping plates 101 of the RGV transport vehicle are designed to firmly fix the conveying frame 210, avoid the conveying frame 210 from shifting due to vibration during the feeding process, and improve the stability of equipment operation; the layout of the slide rail 110 and the saw body 120 realizes the automated connection of materials from conveying to cutting, reduces manual transfer links, and improves production continuity.

[0030] Preferably, multiple sets of ball bearings 221 are installed on both sides of the baffle 220. The ball bearings 221 are evenly distributed in the vertical direction on both sides of the baffle 220. The ball bearings 221 are rotatably connected to the baffle 220. The design of the ball bearings 221 on both sides of the baffle converts the sliding friction between the adjusting frame 230 and the baffle 220 into rolling friction, reducing the resistance when the adjusting frame 230 is raised and lowered, making height adjustment easier and smoother. The even distribution of the ball bearings 221 provides multiple stable locking points for the adjusting frame 230 to meet the conveying needs of materials of different heights.

[0031] Preferably, the bottom of the conveying frame 210 is hollow, and the adjusting frame 230 is provided with an elastic element 240 that engages with the ball bearing 221. The elastic element 240 is fixedly connected to the lower side of the inner wall of the adjusting frame 230. The hollow design at the bottom of the conveying frame 210 facilitates the direct drop of material debris into the receiving frame 310, preventing debris from accumulating in the conveying area. The engagement of the elastic element 240 with the ball bearing 221 can effectively limit and fix the adjusting frame 230, thereby allowing for better stacking of more materials and improving the feeding efficiency.

[0032] Preferably, hydraulic tanks 370 are fixed at both ends of the conveying frame 210, and a piston rod 380 is slidably connected inside the hydraulic tank 370. The top end of the piston rod 380 is fixedly connected to the cross plate 250.

[0033] Preferably, a multi-stage telescopic tube 360 ​​is connected to one side of the hydraulic tank 370. The multi-stage telescopic tube 360 ​​has a folded structure with multiple bends. An abutment plate 350 is fixed to the end of the multi-stage telescopic tube 360. Connecting blocks 330 are fixed to both ends of the two sets of scrapers 320. The connecting blocks 330 are fixed to the belt 340. The folded structure of the multi-stage telescopic tube 360 ​​enables long-distance telescopic extension and contraction within a limited space, saving space occupied by the equipment. Its linkage design with the hydraulic tank 370 and the abutment plate 350 transmits the power of feeding adjustment to the cleaning component 300, providing power for the movement of the scraper 320, realizing the linkage of feeding and cleaning functions. The fixing of the connecting block 330 to the belt 340 ensures that the power is stably transmitted to the scraper 320.

[0034] Preferably, the inner wall of the belt 340 is provided with pulleys 341 on both sides, which are rotatably connected to the receiving frame 310.

[0035] Preferably, the upper and lower ends of the belt 340 are fixedly connected to the connecting blocks 330 on the two sets of scrapers 320, respectively, and the abutment plate 350 is fixedly connected to one of the connecting blocks 330. The design of the belt 340 connecting to the two sets of scrapers 320 allows the other set of scrapers 320 to move synchronously in the opposite direction when one set of scrapers 320 moves, thereby improving the debris cleaning efficiency. The fixed connection between the abutment plate 350 and the connecting block 330 ensures that the power of the multi-stage telescopic tube 360 ​​is efficiently transmitted to the scrapers, reducing power loss.

[0036] Preferably, the extension stroke of the multi-stage telescopic tube 360 ​​is adapted to the sliding stroke of the piston rod 380. When the piston rod 380 is fully pressed into the hydraulic tank 370, the multi-stage telescopic tube 360 ​​extends to its maximum length, driving the scraper 320 to move to the edge of the receiving frame 310.

[0037] Preferably, the inner walls of the receiving frame 310 are provided with gaps 391 on both sides for debris to be removed. By setting the gaps 391, the debris inside the receiving frame 310 can slide out from them, which facilitates the collection of debris.

[0038] Preferably, by placing the material to be cut into the conveyor frame 210, lifting the horizontal plates 250 on both sides causes the adjusting frame 230 to rise, which in turn causes the elastic element 240 to move synchronously. The elastic element 240 engages with the ball bearing 221, effectively limiting and fixing the adjusting frame 230, thereby allowing for better stacking of more material and improving feeding efficiency. At the same time, the adjusting frame 230 and the baffle 220 effectively prevent material from falling during transportation. When the material is cut and then conveyed away again, because there will be residual debris on the cut material, when the material is put back into the conveyor frame 210, the debris will fall into the receiving frame 310 through the hollow at the bottom of the conveyor frame 210, which can remove metal debris and dust generated during cutting in real time, avoiding secondary pollution from manual cleaning and improving cleaning efficiency. When the processed material is removed, pressing the horizontal plate 250 lowers the adjusting frame 230. At the same time, the horizontal plate 250 drives the piston rod 380 to squeeze the oil inside the hydraulic tank 370, allowing the oil to enter the multi-stage telescopic tube 360. Under pressure, the multi-stage telescopic tube 360 ​​extends and pushes the abutment plate 350 to move. The abutment plate 350 drives a set of scrapers 320 to move through the connecting block 330. While moving, the connecting block 330 drives the belt 340 to rotate along the pulley 341, which in turn drives another set of connecting blocks 330 to move another set of scrapers 320. This causes the scrapers 320 on both sides to move relative to each other, pushing the debris inside the receiving frame 310 to both sides. The debris can then slide through the gap 391 onto the inclined plate 390 and finally fall from the inclined plate 390 into the collection box 3910, facilitating the subsequent centralized processing of the debris by the staff.

[0039] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The embodiments and features described in this application can be arbitrarily combined without conflict. The protection scope of this utility model should be defined as the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims.
