Description

Technical Field

[0001] This utility model is a flexible cutting mechanism for corrugated cardboard. Background Technology

[0002] In the production and processing of corrugated cardboard, the cutting process directly affects the dimensional accuracy and edge quality of the product. Existing corrugated cardboard cutting mechanisms typically use rigid metal blade assemblies, which work in conjunction with movable cutter assemblies to complete the cutting. However, this traditional structure has certain technical drawbacks in practical applications, affecting the cutting effect and the service life of the equipment.

[0003] First, because the cutting blade assembly needs to be manually adjusted to align with the blade groove, alignment deviations can easily occur during the cutting process. When the cutter descends, if it is not precisely aligned with the blade groove, the blade may rub against the groove wall, affecting not only the cutting quality but also potentially causing burrs or unevenness at the cut edges. Furthermore, long-term operational errors can lead to a decrease in equipment precision, causing errors to accumulate and further reducing cutting stability.

[0004] Secondly, friction between the blade and the groove exacerbates component wear. Since the groove is typically made of rigid metal, significant wear occurs when the cutter deviates or is subjected to excessive force. This not only shortens the cutter's lifespan but also increases groove wear, leading to higher equipment maintenance costs. Furthermore, wear affects cutting quality, increases operational uncertainty, and may even necessitate frequent parts replacements, impacting production efficiency.

[0005] Furthermore, existing cutter grooves mostly employ an integral structure, making maintenance and replacement processes complex. When the cutter groove wears down, the entire piece often needs to be replaced, but the machining cost of metal is high, and frequent replacements increase production costs. Simultaneously, the cumbersome disassembly and assembly process affects production efficiency and may cause prolonged equipment downtime, thus impacting overall production progress. Therefore, existing technology urgently needs improvement to enhance cutting blade alignment accuracy, reduce cutter and cutter groove wear, optimize maintenance methods, reduce replacement costs, and increase equipment lifespan and production efficiency. Utility model content:

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a flexible cutting mechanism for corrugated cardboard.

[0007] A flexible cutting mechanism for corrugated cardboard includes an upper roller and a lower roller. A cutter assembly is provided on the outer side of the upper roller, and the cutter assembly can move along the axial direction of the upper roller. A knife groove assembly is provided on the outer side of the lower roller. The knife groove assembly includes an annular sleeve, which is a split structure. The annular sleeve includes a sleeve body and a groove body. The sleeve body is annular in shape, and its outer arc surface has an annular clearance notch for mounting in the groove body. The groove body is annular in shape, and its outer arc surface has an annular clearance groove for cooperating with the cutter. The groove body is made of a flexible material.

[0008] Furthermore, the groove and the sleeve are connected by a tenon and mortise joint.

[0009] Furthermore, the tank and the sleeve are fixedly connected by bolts.

[0010] Furthermore, the flexible material is one of rubber, nylon, or silicone.

[0011] Furthermore, the material of the cutter in the cutter assembly is alloy steel or ceramic.

[0012] Beneficial Effects: Compared with existing technologies, this utility model optimizes the design of the blade groove assembly, replacing the original hard metal material with a flexible material and adopting a split structure. The flexible material groove effectively reduces the contact friction between the cutter and the blade groove, reducing cutter wear and extending cutter life. Simultaneously, the flexible groove possesses a certain deformation capacity during cutting, adapting to the instantaneous impact force of the cutter, further improving cutting stability and accuracy. Furthermore, with the split structure, the blade groove assembly consists of a sleeve and a groove; the groove can be independently disassembled and replaced, eliminating the need to replace the entire blade groove assembly, significantly reducing maintenance and replacement costs and improving equipment efficiency and economy.

[0017] 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.

[0018] A flexible cutting mechanism for corrugated cardboard includes an upper roller 2 and a lower roller 1. A cutter assembly 3 is provided on the outer side of the upper roller 2, and the cutter assembly 3 can move axially along the upper roller 2. A knife groove assembly 4 is provided on the outer side of the lower roller 1. The knife groove assembly 4 includes an annular sleeve, which is a split structure. The annular sleeve includes a sleeve body 5 and a groove body 6. The sleeve body 5 is an annular structure, and its outer arc surface has an annular clearance notch 8 for mounting to the groove body 6. The groove body 6 is an annular structure, and its outer arc surface has an annular clearance groove 7 for cooperating with the cutter. The groove body 6 is made of a flexible material.

[0019] In this example, the groove 6 and the sleeve 5 are connected by a tenon and mortise joint.

[0020] In this example, the groove 6 and the sleeve 5 are fixedly connected by bolts.

[0021] In this example, the flexible material is one of rubber, nylon, or silicone.

[0022] In this example, the material of the cutter in the cutter assembly 3 is alloy steel or ceramic.

[0023] Working principle: Existing blade groove assembly 4 typically adopts a one-piece rigid metal structure. During the cutting of corrugated cardboard, the position of the cutting blade assembly 3 needs to be manually adjusted to ensure that the cutting blade is aligned with the blade groove. However, due to the error in manual adjustment, the cutting blade may make offset contact with the blade groove wall during cutting, thereby generating greater friction, accelerating the wear of the cutting blade and blade groove, affecting cutting accuracy and increasing maintenance costs.

[0024] To overcome the aforementioned problems, this invention optimizes the design of the blade groove assembly 4, replacing the original hard metal material with a flexible material and adopting a split structure. The flexible groove body 6 effectively reduces contact friction between the cutter and the blade groove, reducing cutter wear and extending cutter life. Simultaneously, the flexible groove body 6 possesses a certain deformation capacity during cutting, adapting to the instantaneous impact force of the cutter, further improving cutting stability and accuracy. Furthermore, with the split structure, the blade groove assembly 4 consists of a sleeve 5 and a groove body 6. The groove body 6 can be independently disassembled and replaced, eliminating the need to replace the entire blade groove assembly 4, significantly reducing maintenance and replacement costs and improving equipment efficiency and economy.

[0025] 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.
