Description

Technical Field

[0001] This utility model relates to the field of corrugated paper processing technology, specifically a corrugated cardboard slitting device. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper (commonly known as "corrugated sheet", "corrugated paper", "corrugated core", "corrugated base paper") and one layer of cardboard (also known as "boxboard"). It has high mechanical strength and can withstand collisions and drops during handling, so it is widely used in packaging, logistics, transportation and other industries.

[0003] Corrugated cardboard slitting equipment reveals many drawbacks when faced with complex slitting tasks. On the one hand, most slitting equipment uses fixed-angle cutters, which cannot flexibly adjust the cutter angle when oblique slitting or other special angle slitting is required. On the other hand, even if some equipment has cutter angle adjustment function, the adjustment method is often not precise enough, the adjustment process is complicated and it is difficult to respond to changes in slitting requirements in real time. During the slitting process, if the cutter angle needs to be adjusted due to temporary changes in cardboard layout, traditional equipment cannot quickly and accurately complete the angle correction, resulting in the slitting cardboard not meeting the design requirements, producing a large number of defective products, and reducing production efficiency and product quality.

[0026] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The corrugated cardboard slitting device provided in this application includes a workbench 1; a support plate 2 is installed on the surface of the workbench 1, a moving component 5 is installed on the bottom inner side of the support plate 2, a lowering component 6 is provided at the bottom of the moving component 5, and a rotating component 7 is installed below the lowering component 6.

[0028] The rotating assembly 7 includes a motor 701, a mounting block 702, and a cutter 703. The output end of the motor 701 is mounted on the mounting block 702, and the cutter 703 is mounted inside the mounting block 702 by bolts. The moving assembly 5 includes a sliding cavity 501, an electric slide rail 502, and a sliding block 503. The sliding cavity 501 is opened inside the support plate 2. The electric slide rail 502 is installed inside the sliding cavity 501, and the sliding block 503 is slidably mounted on the surface of the electric slide rail 502. The lowering assembly 6 includes a hydraulic cylinder 601 and a mounting bracket 602. The hydraulic cylinder 601 is installed below the sliding block 503, and the mounting bracket 602 is fixedly installed below the hydraulic cylinder 601. The motor 701 is installed inside the mounting bracket 602, and the output end of the motor 701 passes through the mounting bracket 602 and is fixedly connected to the mounting block 702.

[0029] Specifically, such as Figures 1 to 5 As shown, when corrugated paper is being slit, the positioning component 4 and the adsorption fixing component 8 work together to position and fix the corrugated paper. The moving component 5 starts adjusting the lateral slitting position of the cutter 703. The electric slide rail 2 502 runs in the slide cavity 501 inside the support plate 2, causing the sliding block 503 to slide along the electric slide rail 2 502. The lowering component 6 drives the rotating component 7 to move laterally as a whole, so that the cutter 703 is aligned with the longitudinal path on the cardboard that needs to be slit. After the position is adjusted, the position of the cutter 703 is then adjusted. The motor 701 is started, and its output end drives the mounting block 702 to rotate. The mounting block 702 drives the cutter 703 to rotate synchronously until the cutter 703 is adjusted to the required cutting angle. Then the lowering component 6 is moved. Upon startup, hydraulic cylinder 601 extends, pushing mounting bracket 602 downward. Mounting bracket 602 drives motor 701, mounting block 702, and cutter 703 to move downward synchronously. Cutter 703 contacts corrugated cardboard and gradually cuts in, completing the cutting operation. During the process, if the lateral cutting position needs to be adjusted, moving component 5 can drive sliding block 503 to move via electric slide rail 2 502, realizing lateral translation of cutter 703. If the cutting angle needs to be changed, motor 701 of rotating component 7 can drive cutter 703 to rotate and adjust again. After slitting is completed, suction fixing component 8 stops pumping air, the negative pressure in air chamber 801 disappears, releasing the suction of cardboard. Electric push rod 403 of positioning component 4 retracts, driving positioning plate 404 to move outward, releasing the positioning restriction on cardboard, and completing one slitting operation.

[0030] Furthermore, the surface of the workbench 1 is symmetrically provided with slide grooves 3, and a positioning component 4 is installed inside the slide grooves 3. The positioning component 4 includes an electric slide rail 401, a slider 402, an electric push rod 403 and a positioning plate 404. The electric slide rail 401 is installed inside the slide groove 3, and the slider 402 is slidably installed on the surface of the electric slide rail 401. The electric push rod 403 is installed on the inner side of the slider 402, and the positioning plate 404 is fixedly installed at one end of the electric push rod 403.

[0031] Specifically, such as Figures 1 to 5 As shown, when the slitting operation begins, the corrugated cardboard to be slitted is first placed on the surface of the workbench 1. At this time, the positioning component 4 is activated first, and the cardboard is positioned according to the slitting requirements. The electric push rod 403 extends and pushes the positioning plate 404 to move inward until the positioning plate 404 is tightly attached to the edge of the corrugated cardboard. Through the combined action of the two positioning plates 404, the cardboard is restricted within the preset slitting area, and the lateral positioning is completed, ensuring that the edge of the cardboard is parallel to the slitting path. The electric slide rail 401 runs inside the slide groove 3, driving the slider 402 to slide along the slide groove 3, thereby adjusting the lateral position of the positioning plate 404 on the surface of the workbench 1.

[0032] Furthermore, the surface of the workbench 1 is provided with an adsorption and fixing component 8, which includes an air cavity 801, air holes 802 and a connecting pipe 803. The air cavity 801 is opened inside the workbench 1, the air holes 802 are opened at equal intervals on the surface of the workbench 1, and the connecting pipe 803 is located at the bottom of the workbench 1 and communicates with the air cavity 801.

[0033] Specifically, such as Figures 1 to 5 As shown, after the corrugated paper to be processed is positioned and moved to the bottom of the cutter 703 by the positioning component 4, the positioned paperboard is reinforced. The connecting pipe 803 is connected to the external air pump. After the air pump is started, the air in the air chamber 801 inside the workbench 1 is extracted through the connecting pipe 803, so that a negative pressure is formed in the air chamber 801. Since the air hole 802 connects the surface of the workbench 1 with the air chamber 801, the negative pressure acts on the bottom of the corrugated paperboard through the air hole 802, generating a uniform adsorption force, which firmly adsorbs the paperboard to the surface of the workbench 1, preventing the paperboard from shifting due to external force during the subsequent cutting process.

[0034] Working Principle: When slitting corrugated paper, the positioning component 4 and the adsorption fixing component 8 work together to position and fix the corrugated paper. The moving component 5 starts to adjust the lateral slitting position of the cutter 703. The electric slide rail 2 502 runs in the slide cavity 501 inside the support plate 2, driving the sliding block 503 to slide along the electric slide rail 2 502. The lowering component 6 drives the rotating component 7 to move laterally as a whole, so that the cutter 703 is aligned with the longitudinal path on the paperboard that needs to be cut. After the position is adjusted, the position of the cutter 703 is then adjusted. The motor 701 is started, and its output end drives the mounting block 702 to rotate. The mounting block 702 drives the cutter 703 to rotate synchronously until the cutter 703 is adjusted to the required cutting angle. Then the lowering component 6 is moved. Upon startup, hydraulic cylinder 601 extends, pushing mounting bracket 602 downward. Mounting bracket 602 drives motor 701, mounting block 702, and cutter 703 to move downward synchronously. Cutter 703 contacts corrugated cardboard and gradually cuts in, completing the cutting operation.

Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
