[0031] Please see Figure 1-5 This utility model provides a technical solution: a multi-layer corrugated cardboard positioning and trimming mechanism, including a pressure plate 1, a base plate 2, and a positioning plate 3. The pressure plate is positioned at the upper end of the base plate. The positioning plate is slidably connected to the base plate. A baffle 9 is fixedly provided on the side of the base plate 2 away from the positioning plate 3. The function of the baffle 9 is to prevent the cardboard from sliding during the trimming process, ensuring the safety and reliability of the entire processing. Multiple positioning antennas 8 are evenly provided on the adjacent side surfaces of the positioning plate 3 and the base plate 2. These positioning antennas 8 play a key role in the positioning and fixing of the multi-layer corrugated cardboard. The positioning antenna 8 includes a base 801 and a contact 802. One end of each of the multiple bases 801 is fixedly installed on the positioning plate 3. Each of the multiple bases 801 forms a cavity 803. The other end surface of each of the multiple bases 801 has a limiting hole 804 penetrating the cavity 803. A limiting block 805 is slidably provided in each of the multiple cavities 803, and the limiting block 805 can slide within the cavity 803. For adjusting the position of the contact 802, multiple limiting blocks 805 are fixedly connected to one end of the positioning rod 806, and the other end of the multiple positioning rods 806 passes through the limiting hole 804 and is fixedly connected to the contact 802. The contact 802 is used to contact the multi-layer corrugated cardboard to achieve the positioning function. A spring 807 is slidably provided on the multiple positioning rods 806. The spring 807 provides elastic force to the positioning rods 806, so that the contact 802 can fit tightly against the multi-layer corrugated cardboard to enhance the positioning effect. When the multi-layer corrugated cardboard is placed on the positioning plate 3, the contact 802 will be pressured by the cardboard and move into the cavity 803, compressing the spring 807. When the cardboard moves to the correct position, the elastic force of the spring 807 will pop the contact 802 out and make tight contact with the cardboard to achieve positioning. The upper surface of the pressure plate 1 is fixedly connected to the connecting plate 1 through the connecting column. A cutter 11 is fixedly provided on the adjacent side of the pressure plate 1 and the positioning plate 3 for trimming the multi-layer corrugated cardboard.

[0032] In some embodiments, anti-slip ridges 12 are uniformly provided on the adjacent side surfaces of the pressure plate 1 and the base plate 2.

[0033] In some embodiments, a mechanical connector is fixedly provided on the upper surface of the connecting plate 10, and the cylinder heads of hydraulic rods 13 are symmetrically fixedly installed on the adjacent side surfaces of the connecting plate 10 and the pressure plate 1, and the cylinder tails of the two hydraulic rods 13 are fixedly connected to the pressure plate 1.

[0034] In some embodiments, slide rods 4 are symmetrically arranged on both sides of the base plate 2. Multiple sliders 5 can slide flexibly on these slide rods 4. Multiple sliders 5 are symmetrically arranged on two slide rods 4. The symmetrical arrangement of the sliders 5 not only ensures the balance of the mechanism, but also improves the accuracy of operation. Two symmetrically arranged sliders 5 form a group. The two symmetrically arranged sliders 5 in each group are fixedly connected to the support plate 6 through the connecting rod at the bottom. The support plate 6 provides stable support for the sliders 5 and ensures stability during the edge trimming process. Support frames 7 are fixedly arranged on both sides of the positioning plate 3. The two support frames 7 are slidably connected to the two slide rods 4. The sliding connection between these support frames 7 and the slide rods 4 allows the positioning plate 3 to be flexibly adjusted according to the thickness and width of the cardboard, thereby achieving precise positioning.

[0035] In some embodiments, the surface of the contact 802 is provided with an anti-slip texture, which increases the friction between the contact and the corrugated cardboard, making the positioning more secure and less prone to displacement during edge trimming, thereby improving the accuracy and efficiency of edge trimming.

[0036] In some embodiments, the outer surfaces of both slide bars 4 are provided with multiple limiting grooves 401, and the inner surfaces of multiple sliders 5 and the connecting parts of the slide bars 4 are fixedly provided with limiting strips 402. The multiple limiting strips 402 are slidably engaged with the limiting grooves 401, making the sliders 5 more stable when sliding on the slide bars 4 and less prone to deviation, thereby further improving the accuracy and efficiency of edge trimming. Through the cooperation between the sliders 5 and the slide bars 4, and the supporting effect of the support plate 6, the distance between the positioning plate 3 and the base plate 2 can be easily adjusted to adapt to multi-layer corrugated cardboard of different thicknesses, achieving precise positioning and edge trimming.

[0037] In some embodiments, both the positioning plate 3 and the base plate 2 are made of high-strength, wear-resistant materials, possessing excellent durability and load-bearing capacity, ensuring stability and reliability under long-term use. Furthermore, this multi-layer corrugated cardboard positioning and trimming mechanism has a simple structure and is easy to operate, significantly improving the trimming efficiency and accuracy of corrugated cardboard, reducing production costs, and is suitable for carton packaging manufacturers of all sizes.

[0038] In some embodiments, the cutter 11 is a high-quality alloy steel cutter with high hardness and wear resistance, which can maintain the sharpness of the blade for a long time and improve the edge trimming effect.

[0039] In some embodiments, the contact 802 is bolted to the positioning rod 806.

[0040] In some embodiments, scales 14 are provided on both sides of the pressure plate 1.

[0041] Working Principle: Based on the thickness and width of the multi-layer corrugated cardboard, the position of the positioning plate 3 is adjusted via the sliding support frame 7 to ensure a suitable distance between the positioning plate 3 and the base plate 2. Then, the multi-layer corrugated cardboard is placed on the base plate 2, making it contact the contact 802 of the positioning contact 8. The contact 802, under the pressure of the cardboard, moves into the cavity 803 and compresses the spring 807. When the cardboard moves to the correct position, the elasticity of the spring 807 ejects the contact 802, ensuring tight contact with the cardboard and achieving positioning. Additionally, by observing the scale 14 on both sides of the pressure plate 1, the height of the pressure plate 1 can be precisely adjusted to align the cutter 11 with the edge of the multi-layer corrugated cardboard. Next, the hydraulic rod 13 is activated, and the cylinder head of the hydraulic rod 13 pushes the connecting plate 10 and the pressure plate 1 downwards. The pressure plate 1 presses against the multi-layer corrugated cardboard, while the cutter 11 trims the edges of the cardboard. After the edge trimming is completed, the hydraulic rod 13 retracts, the pressure plate 1 and the cutter 11 rise, and the trimmed multi-layer corrugated cardboard is removed, completing the entire edge trimming process.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
