Description

Technical Field

[0001] This utility model belongs to the technical field of lithium corrugated cardboard box production equipment, specifically relating to a corrugated paper cutting device for corrugated cardboard box production. Background Technology

[0002] Corrugated cardboard boxes hold a crucial position in the packaging industry due to their numerous advantages, including lightweight, high strength, good cushioning performance, and recyclability. They are widely used in various fields such as food, electronics, home appliances, and logistics. With the continuous growth of market demand for corrugated cardboard boxes and the increasing demands for their quality, the production process of corrugated cardboard boxes is also constantly developing and improving. In the production process, the cutting of corrugated paper is a key step; its cutting accuracy and efficiency directly affect subsequent printing, forming, and other processes, thus impacting the product quality and production efficiency of the corrugated cardboard boxes.

[0003] Corrugated paper contains a large amount of fiber, which easily sticks to the side wall of the blade during the cutting process. Existing devices lack a dedicated cleaning structure, requiring frequent manual shutdowns for cleaning (averaging 1-2 times per hour). This not only interrupts the production process but also accelerates blade wear due to friction during cleaning, shortening the blade's lifespan (usually requiring replacement after about 5000 cuts). The accumulation of residual fibers further affects the cutting quality. Therefore, those skilled in the art have provided a corrugated paper cutting device for corrugated box production to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a corrugated paper cutting device for corrugated box production that has a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: it includes a frame, and a limiting clamping component is provided on both sides of the top middle of the frame. A gantry frame is fixedly installed on the top of the frame and on one side of the limiting clamping component. A cutting blade is slidably provided inside the gantry frame. An clearance groove is provided directly below the gantry frame and on the top of the frame. A cleaning brush for cleaning the side wall of the cutting blade is rotatably connected to the inner side wall of the clearance groove.

[0006] As a further optimization of this utility model, two meshing transmission gears are rotatably connected to one side of the inner wall of the clearance groove, one end of each of the two cleaning brushes is fixedly connected to the side wall of the corresponding transmission gear, and a second servo motor is fixedly installed on the side wall of the frame at one side of any transmission gear, and the output end of the second servo motor is fixedly connected to the other side wall of the corresponding transmission gear.

[0007] As a further optimization of this utility model, the limiting clamping assembly includes an adjustment groove opened on the top of the frame. A double-ended lead screw is rotatably connected to the inner side wall of the adjustment groove. Slider blocks that are slidably connected inside the adjustment groove are threaded on both sides of the outer side wall of the double-ended lead screw.

[0008] As a further optimization of this utility model, a clamping seat is installed at the top center of each of the two electric sliders, the two clamping seats are symmetrically distributed, and an electric push rod is fixedly installed on both sides of the top of each of the two clamping seats.

[0009] As a further optimization of this utility model, the output ends of the two electric push rods slide through the top of the corresponding clamping base, and the output ends of the two electric push rods are respectively fixedly installed with clamping plates that are slidably connected inside the corresponding clamping base.

[0010] As a further optimization of this utility model, a first servo motor is fixedly installed on the side wall of the frame and on one side of the corresponding adjustment slot, and the output end of the first servo motor is fixedly connected to one end of the double-headed lead screw.

[0011] As a further optimization of this utility model, a hydraulic cylinder is fixedly installed at the top center of the gantry frame.

A dust collection box communicating with the clearance groove is fixedly installed on the bottom of the frame, and a dust collection drawer is slidably connected through the side wall of the dust collection box.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model adopts a double-headed screw drive slide rail synchronous adjustment spacing, combined with the lateral movement of the electric slider, which can flexibly adapt to different specifications of corrugated paper, avoiding the manual adjustment error of traditional positioning structure. The clamping component drives the clamping plate to press down vertically through the electric push rod, forming a rigid clamp with the clamping seat, solving the problem of paper displacement caused by unstable clamping in traditional equipment.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, a corrugated paper cutting device for corrugated box production includes a frame 1, a limiting clamping component, a gantry frame 9, a cutting component, a cleaning component, and a dust collection structure. The frame 1 is the basic support structure of the device. The limiting clamping component is used to fix the corrugated paper. The cutting component is installed on the gantry frame 9 to realize the cutting action. The cleaning component cleans the cutting blades. The dust collection structure collects the debris generated during cutting.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the limiting clamping assembly includes an adjustment groove on the top of the frame 1. A double-ended lead screw 21 is rotatably connected to the inner wall of the adjustment groove via bearings. Slider blocks, threaded and slidably connected inside the adjustment groove, are threaded on both sides of the outer wall of the double-ended lead screw 21. The threads of the two sliders are opposite, allowing them to move towards or away from each other when the double-ended lead screw 21 rotates. A slide rail 2 is bolted to the top of each slider. An electric slider 3 is slidably connected to the outer wall of each slide rail 2, allowing the electric slider 3 to move along the length of the slide rail 2. A clamping seat 4 is bolted to the middle of the top of each of the two electric sliders 3. The two clamping seats 4... The two clamping seats 4 are respectively bolted to the top sides of each other, and electric push rods 6 are respectively bolted to the top of the corresponding clamping seats 4. The output ends of the two electric push rods 6 slide through the top of the corresponding clamping seats 4. The output ends of the two electric push rods 6 are respectively bolted to the clamping plates 7 which are slidably connected inside the corresponding clamping seats 4. The bottom of the clamping plates 7 is affixed with rubber anti-slip pads to avoid damage to the corrugated paper during clamping. The side wall of the frame 1 and located on one side of the corresponding adjustment slot is bolted to a first servo motor 8. The output end of the first servo motor 8 is fixedly connected to one end of the double-ended lead screw 21 through a coupling, which can drive the double-ended lead screw 21 to rotate.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a gantry 9 is bolted to the top of the frame 1 and to one side of the limiting clamping assembly. A hydraulic cylinder 10 is bolted to the middle of the top of the gantry 9. The output end of the hydraulic cylinder 10 slides through the middle of the top of the gantry 9 and is bolted to a connecting plate 11. Connecting rods 13 are bolted to the four corners of the bottom of the connecting plate 11. The bottom of the four connecting rods 13 is bolted to a mounting plate 12. A cutting blade 14 is bolted to the bottom of the mounting plate 12. The cutting blade 14 can move up and down with the mounting plate 12 to perform the cutting action.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a clearance groove 5 is provided directly below the gantry 9 and at the top of the frame 1. A symmetrically distributed cleaning brush 15 is rotatably connected to the inner wall of the clearance groove 5. The bristles of the cleaning brush 15 are made of wear-resistant nylon and can contact the side wall of the cutting blade 14. Two meshing transmission gears 20 are rotatably connected to one side of the inner wall of the clearance groove 5. One end of each of the two cleaning brushes 15 is fixedly connected to the side wall of the corresponding transmission gear 20 by bolts. A first... Two servo motors 16 are fixedly connected to the other side wall of the corresponding transmission gear 20 via a coupling. The top of the frame 1, and the front and rear sides of the clearance groove 5, are both fixedly installed with pads 17 by bolts. The pads 17 are made of hard rubber and can provide support for the corrugated paper during cutting. The bottom of the frame 1 is fixedly installed with a dust collection box 19 that communicates with the clearance groove 5 by bolts. The side wall of the dust collection box 19 is slidably connected with a dust collection tray 18, which is used to collect paper scraps and debris generated during cutting.

[0028] It should be noted that when using this utility model: according to the width of the corrugated paper, the first servo motor 8 is started, and the first servo motor 8 drives the double-headed lead screw 21 to rotate, so that the two sliders move towards or away from each other in the adjustment groove, driving the two slide rails 2 and the clamping seat 4 to adjust the distance until it matches the width of the corrugated paper. The corrugated paper is placed between the two clamping seats 4, and the electric slider 3 is started. The electric slider 3 moves along the slide rail 2, driving the clamping seat 4 to move to the two ends of the corrugated paper. The electric push rod 6 is started, and the output end of the electric push rod 6 extends, pushing the clamping plate 7 to move downward until the clamping plate 7 is in close contact with the corrugated paper, thus completing the fixing of the corrugated paper. Under the action of the electric slider 3, the fixed corrugated paper is transported to the cutting assembly.

[0029] Cutting process: Start hydraulic cylinder 10, extend the output end of hydraulic cylinder 10, push connecting plate 11, connecting rod 13, mounting pressure plate 12 and cutting blade 14 downward. After cutting blade 14 contacts corrugated paper, it continues to move downward to achieve cutting. Pad plate 17 supports corrugated paper to prevent deformation during cutting. During cutting, connecting rod 13 can buffer the impact force during cutting, reduce the vibration of the device, and protect cutting blade 14 and corrugated paper. After cutting is completed, the output end of hydraulic cylinder 10 retracts, driving cutting blade 14 and other components to return to their original position.

[0030] Blade cleaning and dust collection: During the cutting process of the cutting blade 14, the cutting blade extends into the clearance groove. At this time, the second servo motor 16 is started. The second servo motor 16 drives the corresponding transmission gear 20 to rotate. Since the two transmission gears 20 mesh with each other, the other transmission gear 20 rotates in the opposite direction, driving the two cleaning brushes 15 to rotate in the opposite direction. The rotating cleaning brushes 15 contact the two side walls of the cutting blade 14 to remove the paper scraps adhering to the blade surface. The removed paper scraps and cutting debris fall into the dust collection drawer 18 in the dust collection box 19 through the clearance groove 5. The debris can be cleaned by periodically removing the dust collection drawer 18.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
