Description

Technical Field

[0001] This utility model relates to the field of feeding equipment for cutting machines, and in particular to a feeding mechanism for a hydraulic gantry cutting machine. Background Technology

[0002] Cutting is a crucial step in the manufacturing process of automotive interior parts, especially when dealing with thin and large materials, such as certain high-grade leathers or synthetic materials, which require extremely high precision and efficiency in cutting. These materials are not only expensive, but their surface quality also directly affects the appearance and texture of the final product. Therefore, ensuring the stability of materials during the cutting process and the efficiency of material collection after cutting has become an urgent problem to be solved.

[0003] Traditional cutting machines, while capable of cutting materials using punches and other mechanisms, suffer from several shortcomings in the feeding process. Due to the thinness and large size of the materials, issues such as material deviation and wrinkling easily occur during feeding. These problems not only affect the cutting accuracy but may also lead to quality issues with the cut materials, such as uneven edges and dimensional deviations. Furthermore, existing cutting machines often require manual removal of each material after cutting, which is not only time-consuming and labor-intensive but also increases the workload of workers and reduces production efficiency.

[0004] Therefore, it is necessary to provide a new feeding mechanism for a hydraulic gantry cutting machine to solve the above-mentioned technical problems. Utility Model Content

A punch is installed inside the cutting machine body, and a support frame is provided inside the cutting machine body. A feeding plate is installed on the top of the support frame, and pressure rollers are symmetrically arranged above the feeding plate. A transmission mechanism is installed between the support frame and the pressure rollers. The transmission mechanism drives the pressure rollers to move to flatten the wrinkled parts on the surface of the material. An adsorption cylinder is provided above the feeding plate, and adsorption tubes are equidistantly connected to the bottom of the adsorption cylinder. A rotating assembly is installed between the support frame and the adsorption cylinder. The rotating assembly drives the adsorption cylinder to rotate to adsorb and collect the cut material. A collection box for collecting the cut material is provided on one side of the feeding plate.

[0007] Preferably, the transmission mechanism includes: a motor, a worm, a worm wheel, and a transmission shaft. The motor is fixedly connected to one side of the support frame, and fixed frames are fixedly connected at equal intervals to the top of the support frame. The worm is symmetrically and rotatably connected inside the fixed frame closer to the motor. The worm is fixedly connected to the output end of the motor. The transmission shaft is symmetrically and rotatably connected at equal intervals between the two fixed frames. Worm wheels are fixedly connected to one end of the two sets of transmission shafts that are far apart from each other. The two worm wheels are meshed with the corresponding worms.

[0008] Preferably, each of the two sets of drive shafts, which are far apart from each other, is fixedly connected to a drive sprocket at both ends, and each of the two sets of drive shafts, which are close together from each other, is fixedly connected to a driven sprocket at both ends. The two sets of drive sprockets and their corresponding driven sprockets are connected by chain drive. The outer walls of the two sets of chains are fixedly connected to mounting seats, and the two sets of mounting seats are rotatably connected to their respective pressure rollers.

[0009] Preferably, the two worm shafts are fixedly connected by a connecting rod, and the threads of the two worms are in opposite directions.

[0010] Preferably, the rotating assembly includes: a second motor, an arc-shaped plate, and a fixed disk. The second motor is fixedly connected to one side of the support frame, and the output end of the second motor is fixedly connected to the adsorption cylinder. A fixed rod is fixedly connected to the other side of the support frame. A fixed disk is fixedly connected to one end of the fixed rod, and the other end of the fixed rod is rotatably connected to the inner wall of the adsorption cylinder. The end of the adsorption cylinder away from the second motor is rotatably connected to the fixed disk. An arc-shaped plate is fixedly connected to the outer wall of the fixed rod, and the outer wall of the arc-shaped plate is in contact with the inner wall of the adsorption cylinder.

[0011] Preferably, a suction fan is provided on the side of the support frame away from the collection box, and the suction fan is connected to the fixed plate through an air duct.

[0012] Preferably, the side of the cutting machine body away from the pressure roller is provided with a conveyor belt perpendicular to the feeding plate, and a baffle is fixedly connected to the side of the conveyor belt near the adsorption cylinder. The baffle has grooves at equal intervals inside that correspond to the adsorption tube.

[0013] Compared with related technologies, the feeding mechanism of the hydraulic gantry cutting machine provided by this utility model has the following beneficial effects:

[0014] Improve cutting accuracy:

[0015] With the set pressure rollers and transmission mechanism, the material can be effectively flattened during the feeding process. The pressure rollers move from the middle of the material to both sides to ensure that the wrinkles on the surface of the material are completely flattened, thereby greatly improving the accuracy of subsequent cutting. The synchronous reverse movement design of the pressure rollers ensures the uniformity and consistency of the flattening effect and avoids cutting quality problems caused by uneven flattening.

[0016] Enhance material stability:

[0017] During the cutting process, the motor continuously drives the pressure roller to flatten the material in the cutting area, effectively preventing problems such as deviation and wrinkles that occur during feeding due to the thinness and large size of the material, and enhancing the stability of the material. This design ensures accurate positioning and stable conveying of the material during the cutting process, further improving the cutting precision and efficiency.

[0018] The design of the adsorption cylinder and rotating assembly enables automatic collection of cut materials. The motor drives the adsorption cylinder to rotate, accurately moving the adsorption tube directly above the cut materials. The suction force generated by the fan holds the materials in place. After rotating 180 degrees counterclockwise, the adsorption tube continues to rotate to the arc plate area. Due to the blocking effect of the arc plate, the suction force inside the adsorption tube disappears, and the materials fall onto the conveyor belt due to their own gravity, eventually being transported into the collection box. This automatic collection method greatly saves the time and labor of manual collection and improves production efficiency. Attached Figure Description

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 5 A feeding mechanism for a hydraulic gantry cutting machine includes: a cutting machine body 1, a feeding plate 4, pressure rollers 5, a transmission mechanism, an adsorption cylinder 6, a rotating assembly, and a collection box 8. A punch 2 is installed inside the cutting machine body 1, and a support frame 3 is provided inside the cutting machine body 1. The feeding plate 4 is installed on the top of the support frame 3, and pressure rollers 5 are symmetrically arranged above the feeding plate 4. A transmission mechanism is installed between the support frame 3 and the pressure rollers 5, and the transmission mechanism drives the pressure rollers 5 to move for pressing. For the wrinkled parts of the flat material surface, an adsorption cylinder 6 is provided above the feeding plate 4. Adsorption tubes 7 are equidistantly connected to the bottom of the adsorption cylinder 6. A rotating component is installed between the support frame 3 and the adsorption cylinder 6. The rotating component drives the adsorption cylinder 6 to rotate and adsorb and collect the cut material. A collection box 8 for collecting the cut material is provided on one side of the feeding plate 4. The transmission mechanism includes: motor 9, worm gear 10, worm wheel 11 and transmission shaft 12. Motor 9 is fixedly connected to one side of the support frame 3. The top of the support frame 3 is equidistantly connected to the motor 9. A fixed frame 13 is fixedly connected. A worm gear 10 is symmetrically and rotatably connected inside the one of the two fixed frames 13 closest to the motor 9. The one of the two worm gears 10 closest to the motor 9 is fixedly connected to the output end of the motor 9. A drive shaft 12 is symmetrically and rotatably connected at equal intervals between the two fixed frames 13. A worm wheel 11 is fixedly connected to one end of each of the two sets of drive shafts 12 that are far apart from each other. The two worm wheels 11 mesh with the corresponding worm gear 10. Both ends of the two sets of drive shafts 12 that are far apart from each other are fixedly connected to a driving sprocket 14. Both ends of the two sets of drive shafts 12 that are close together are fixedly connected to a driven sprocket 15. The two sets of driving sprockets 14 and the corresponding driven sprockets 15 are connected by chain drive. Mounting seats are fixedly connected to the outer walls of both sets of chains. The two sets of mounting seats are rotatably connected to the corresponding pressure rollers 5. The two worm gears 10 are fixedly connected to each other by a connecting rod, and the threads of the two worm gears 10 are opposite in direction.

[0028] It should be noted that: the operator neatly stacks the material to be cut on the feeding plate 4, then starts the conveying mechanism, the feeding plate 4 begins to move, and the material is conveyed to the cutting area. When the material reaches the designated position, the conveying mechanism stops running, the cutting machine body 1 begins to prepare for the cutting action, the punch 2 of the cutting machine body 1 descends under the drive of the hydraulic system to cut the material. After the cutting is completed, the punch 2 returns to its original position, the conveying mechanism sends the cut material out of the cutting area, and prepares for the next feeding.

[0029] Please see Figure 2 , Figure 3 and Figure 5 The rotating assembly includes: a second motor 16, an arc plate 17, and a fixed plate 18. The second motor 16 is fixedly connected to one side of the support frame 3. The output end of the second motor 16 is fixedly connected to the adsorption cylinder 6. The other side of the support frame 3 is fixedly connected to a fixed rod 19. One end of the fixed rod 19 is fixedly connected to the fixed plate 18. The other end of the fixed rod 19 is rotatably connected to the inner wall of the adsorption cylinder 6. The end of the adsorption cylinder 6 away from the second motor 16 is rotatably connected to the fixed plate 18. The outer wall of the fixed rod 19 is fixedly connected to the arc plate 17. The outer wall of the arc plate 17 fits against the inner wall of the adsorption cylinder 6. A suction fan 20 is provided on the side of the support frame 3 away from the collection box 8. The suction fan 20 is connected to the fixed plate 18 through a duct. A conveyor belt 21 perpendicular to the feeding plate 4 is provided on the side of the cutting machine body 1 away from the pressure roller 5. A baffle 22 is fixedly connected on the side of the conveyor belt 21 close to the adsorption cylinder 6. The baffle 22 has grooves at equal intervals corresponding to the adsorption tube 7 inside.

[0030] It should be noted that the baffle 22, which is fixedly connected to one side of the conveyor belt 21, has grooves that are equidistantly opened inside, corresponding to the adsorption tube 7. When the adsorption tube 7 adsorbs the cut material and rotates to the area of ​​the arc plate 17 to place the material on the conveyor belt 21, the design of the baffle 22 prevents the material from falling outside the conveyor belt 21. The groove design inside ensures that the adsorption tube 7 is not obstructed by the baffle 22 during the rotation process.

[0031] The working principle of the feeding mechanism of the hydraulic gantry cutting machine provided by this utility model is as follows:

[0032] First, the material is placed on the feeding plate 4. Then, the conveying mechanism is started, and the feeding plate 4 begins to feed the material into the processing area of ​​the cutting machine body 1.

[0033] Flattening process:

[0034] The material first passes through the pressure roller 5. At this time, the worm gears 10 rotatably connected at both ends of the fixed frame 13 are fixedly connected by the connecting rod. When the motor 9 starts, its output end is fixedly connected to one of the worm gears 10, and drives the other worm gear 10 to rotate synchronously through the connecting rod.

[0035] Since the threads of the two worms 10 are in opposite directions, they mesh with the worm gears 11 at one end of the drive shafts 12 that are far apart from each other between the fixed frame 13, so the two drive shafts 12 will start to rotate in opposite directions.

[0036] Two drive shafts 12 that are far apart from each other are fixedly connected to drive sprockets 14 at both ends. These drive sprockets 14 are connected to driven sprockets 15 at both ends of the two drive shafts 12 that are close to each other via chain drive. As the drive shafts 12 rotate, the chain begins to move and drives the pressure rollers 5 that are rotatably connected between the two sets of chains via the mounting base to move along the rotation trajectory of the chain.

[0037] Since the threads of the two worm gears 10 are opposite, the two sets of chains rotate in opposite directions, which in turn drives the two pressure rollers 5 to move from the middle of the material to both sides, and to flatten the wrinkled parts of the material surface to ensure the quality of subsequent cutting. After the pressure rollers 5 complete the flattening action from the middle of the material to both sides, they return to the end of the two sets of chains that are close to each other and stop waiting for the next flattening operation.

[0038] Cutting process:

[0039] Subsequently, the feeding plate 4 continues to feed material. When the material moves with the feeding plate 4 to the processing area below the cutting machine body 1, the cutting machine body 1 starts to work.

[0040] The fixing plate inside the cutting machine body 1 fixes the material in the processing area. Then the punch 2 starts to cut the material. At the same time, the motor 9 starts again and repeats the above steps to drive the pressure roller 5 to flatten the material in the cutting area to ensure the cutting accuracy.

[0041] Collection process:

[0042] After the cutting is completed, the fixed plate inside the cutting machine body rises, and the feeding plate 4 continues to move, conveying the flattened material to the processing area below the cutting machine body 1. The cut material is then moved to the unloading area on one side of the cutting machine body 1.

[0043] While the cutting machine body 1 processes the flattened material, the second motor 16 and the suction fan 20 are started. The output end of the second motor 16 drives the suction cylinder 6 to rotate, rotating the suction tube 7 at its bottom from the area of ​​the arc plate 17 to directly above the cut material. Due to the action of the suction fan 20, the suction tube 7 generates suction force, which sucks up the cut material. As the second motor 16 continues to rotate, the suction tube 7 rotates 180 degrees counterclockwise and then continues to rotate counterclockwise to the area of ​​the arc plate 17. Since the arc plate 17 is fixedly connected to the fixing rod 19 inside the suction cylinder 6, and one end of the fixing rod 19 is fixedly connected to the support frame 3, the arc plate 17 is stationary when the suction cylinder 6 rotates. At this time, the suction force inside the suction tube 7 is blocked by the arc plate 17. The cut material falls onto the conveyor belt 21 on one side of the cutting machine body 1 due to its own weight. The conveyor belt 21 transports the collected material to the collection box 8 on one side, completing the collection process.

[0044] Subsequently, the adsorption tube 7 stops in the area of ​​the arc plate 17, and the motor 16 and the suction fan 20 stop working, waiting for the next material collection.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
