Description

Technical Field

[0001] This utility model is a cutting and pressing top roller for anti-warping corrugated cardboard boxes. Background Technology

[0002] Corrugated cardboard boxes are a widely used form of packaging in the modern packaging industry. They are typically formed by cutting, folding, gluing, or stapling corrugated cardboard. The cutting quality of the corrugated cardboard directly affects the forming accuracy and performance of the box; therefore, the cutting process plays a crucial role in the production of corrugated cardboard boxes.

[0003] Currently, corrugated cardboard is typically cut using a cutting machine. Traditional cutting machines generally use a pair of rotating pressure rollers to feed the corrugated cardboard and a cutting blade to continuously cut it. However, in actual production, incomplete cutting often occurs, meaning that portions of the corrugated cardboard that should be completely separated still retain a small amount of adhesion. This problem is mainly caused by the following factors:

[0004] Insufficient cutting depth: The limited travel of the cutting blade against the corrugated cardboard causes the blade to fail to cut through the cardboard completely, especially when the cardboard is thick or has high rigidity.

[0005] Instability during the conveying process: During the conveying process of corrugated cardboard by the pressing rollers, uneven force or deformation may affect the cutting effect, causing the cutting blade to fail to make full contact with the cardboard, thus affecting the cutting depth.

[0006] Corrugated cardboard thickness variation: Corrugated cardboard of different batches or specifications has different thicknesses. Traditional pressing rollers usually use a fixed gap design, which cannot be adjusted according to the changes in cardboard thickness. This results in thicker cardboard not being effectively pressed, while thinner cardboard may slide due to excessive gaps, affecting cutting accuracy.

[0007] To address these issues, some improvements have proposed adding auxiliary clamping mechanisms or adjusting the cutting blade stroke. However, these methods often increase equipment complexity and require frequent adjustments to cutting parameters, impacting production efficiency. Therefore, there is an urgent need for a pressing device that can improve cutting thoroughness and adapt to corrugated cardboard of different thicknesses, thereby enhancing the quality and efficiency of corrugated box production. Utility model content:

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cutting and pressing top roller for anti-warping corrugated cardboard boxes.

[0009] A cutting and pressing top roller for anti-warping corrugated cardboard boxes includes an upper roller and a lower roller. The outer arc-shaped surface of the lower roller is provided with at least one first top block that is higher than the outer arc-shaped surface of the lower roller and arranged along its axial direction. The upper roller is above the lower roller. Corrugated cardboard is placed between the upper roller and the lower roller. The rotation directions of the upper roller and the lower roller are opposite.

[0010] Furthermore, the front and rear edges of the first top block smoothly engage with the outer arcuate surface of the lower roller.

[0011] Furthermore, the upper surface of the first top block is a smooth curved surface.

[0012] Furthermore, multiple second top blocks are spaced apart on the upper end face of the top block.

[0013] Furthermore, the second top block is made of an elastic material.

[0014] Furthermore, the elastic material is rubber.

[0015] Furthermore, the upper surface of the second top block is a smooth curved surface, and its front and rear edges smoothly join the upper surface of the first top block.

[0016] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0017] Improved cutting thoroughness: The lifting effect of the first top block increases the stroke of the corrugated cardboard and the cutter, ensuring that the corrugated cardboard can be completely cut and separated, avoiding residual adhesion.

[0018] Adaptable to corrugated cardboard of different thicknesses: The second top block is made of elastic material, which can adapt to the changes in the thickness of the corrugated cardboard to achieve reliable clamping effect, while avoiding jamming problems caused by too small gaps.

[0019] Ensure smooth conveying: The design of both the first and second top blocks adopts a smooth transition structure to avoid damage to the corrugated cardboard during conveying, thereby improving production efficiency and product quality.

[0020] Enhanced equipment compatibility: This device is suitable for the production of corrugated cardboard of different specifications, which improves the compatibility and applicability of the equipment, reduces the frequency of equipment adjustments due to changes in cardboard thickness, and improves production convenience.

[0024] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0025] A cutting and pressing top roller for anti-warping corrugated cardboard boxes includes an upper roller 4 and a lower roller 1. The outer arc-shaped surface of the lower roller 1 is provided with at least one first top block 2 that is higher than the outer arc-shaped surface of the lower roller 1 and arranged along its axial direction. The upper roller 4 is above the lower roller 1. Corrugated cardboard 5 is placed between the upper roller 4 and the lower roller 1. The rotation directions of the upper roller 4 and the lower roller 1 are opposite.

[0026] In this example, the front and rear edges of the first top block 2 smoothly engage with the outer arcuate surface of the lower roller 1.

[0027] In this example, the upper surface of the first top block 2 is a smooth curved surface.

[0028] In this example, multiple second top blocks 3 are provided at intervals on the upper surface of the top block.

[0029] In this example, the material of the second top block 3 is an elastic material.

[0030] In this example, the elastic material is rubber.

[0031] In this example, the upper surface of the second top block 3 is a smooth curved surface, and its front and rear edges smoothly join the upper surface of the first top block 2.

[0032] Working Principle: In traditional cutting processes, corrugated cardboard 5 often cannot be completely cut through, resulting in some adhesion remaining in areas that should be completely separated. This invention addresses this by adding a first top block 2 to the surface of the lower roller 1, which lifts the corrugated cardboard 5 during transport, thereby increasing the effective stroke of the cutter and allowing the cutter to cut to the bottom for complete separation. Furthermore, the front and rear edges of the first top block 2 smoothly engage with the outer arc-shaped surface of the lower roller 1, ensuring smooth passage of the corrugated cardboard 5 during transport without jamming or damage.

[0033] To accommodate corrugated cardboard 5 of varying thicknesses, the upper surface of the first top block 2 is provided with multiple spaced-apart second top blocks 3. The second top blocks 3 are made of an elastic material, such as rubber, whose elastic properties allow them to effectively compress corrugated cardboard 5 of different thicknesses. When encountering thicker corrugated cardboard 5, the second top block 3 will compress and deform downwards to a greater extent, while when encountering thinner corrugated cardboard 5, the deformation of the second top block 3 will be smaller. This ensures that the corrugated cardboard 5 can be stably conveyed under different thickness conditions, preventing jamming or damage due to changes in spacing.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
