Description

Technical Field

[0001] The utility model relates to the technical field of cardboard cutting, in particular to a corrugated cardboard cutting mechanism. Background Art

[0002] In the modern packaging industry, corrugated cardboard is a common packaging material that is widely used to protect, transport and display various goods. However, in some cases, corrugated cardboard alone cannot meet specific packaging needs, so lamination is required. Lamination can give corrugated cardboard stronger water resistance, wear resistance and visual effects, while providing additional protection to ensure the safety and durability of packaging. Lamination is usually performed using a laminating machine or packaging machine, and different laminating materials and laminating technologies are used to meet different product and packaging needs.

[0003] In order to ensure full coverage of the film, the corrugated cardboard and the film layer will be enlarged and reserved for cutting edges. The corrugated cardboard after filming usually needs to be cut to meet the needs of products of different sizes and shapes. The existing cutting is usually carried out on a laminating machine or a packaging machine, which is generally a semi-automatic cutting device. During operation, it is necessary to perform fixed-distance cutting or timed cutting, that is, a cam is used to control the tool or the number of revolutions of the cutting motor to synchronize the transportation speed of the cutting material. The overall debugging is difficult, and only a single horizontal cutting or a single vertical cutting can be performed, and complex patterns with composite layers cannot be cut. Therefore, improvement is needed. Utility Model Content

The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] like Figure 1-Figure 3 As shown, a corrugated cardboard cutting mechanism comprises: two clamping plates 100 arranged opposite to each other, at least one feeding channel 110 connected to each other is formed between the two clamping plates 100; the feeding channel 110 is sequentially provided with a cardboard feeding roller group 200, a laminating feeding roller group 300, a transverse cutting assembly 400 and a longitudinal cutting assembly 500;

[0035] The paperboard feeding roller group 200 is used for feeding paperboard; in this embodiment, at least two paperboard feeding roller groups 200 are provided and are distributed at the front and rear ends of the feeding channel 110. By distributing at least two paperboard feeding roller groups 200 at the front and rear ends of the feeding channel 110, it can be ensured that the front and rear end tension of the paperboard is uniform during lamination and cutting, thereby ensuring the flatness of the paperboard during the lamination and cutting process;

[0036] Specifically, the paperboard feed roller group 200 includes a relatively rolling feed roller 210 and a feed drive roller 220; the relatively rolling feed roller 210 and the feed drive roller 220 are used to drive the paperboard forward by squeezing, which can ensure that the paperboard is kept in an appropriate tension state when entering the cutting mechanism, which is conducive to the stable processing;

[0037] Furthermore, the feed roller 210 is connected to a first gap control assembly 230. In this embodiment, the first gap control assembly 230 is a screw spring seat control assembly. Through the first gap control assembly 230, the gap between the feed roller 210 and the feed drive roller 220 can be adjusted to adapt to different processing parameters, so that the cutting mechanism is more flexible and applicable to corrugated cardboards of different specifications.

[0042] The cutter roller 510 is connected to a third gap control assembly 530. In this embodiment, the third gap control assembly 530 is a screw spring seat control assembly. Through the third gap control assembly 530, the gap between the cutter roller 510 and the force roller 520 can be adjusted to adapt to different processing parameters and ensure the accuracy and flexibility of cutting.

[0043] In order to ensure the flatness and uniform thickness of the cardboard entering the cutting mechanism, a cardboard pre-pressing assembly 600 is provided at the front side of the cardboard feeding roller group 200; the cardboard pre-pressing assembly 600 includes a pre-pressing cylinder 610 and a pre-pressing roller 620 which are arranged opposite to each other; a pressing plate is connected to the output end of the pre-pressing cylinder 610; the pressing plate is aligned with the pre-pressing roller 620; through the cardboard pre-pressing assembly 600, including the pre-pressing cylinder 610, the pre-pressing roller 620 and the aligned pressing plate, it can be ensured that the cardboard enters the cutting mechanism with a set gap, thereby ensuring a normal processing flow;

[0044] In this embodiment, the cardboard feed roller group 200, the laminating feed roller group 300, and the longitudinal cutting assembly 500 are driven and connected to a master control motor (not shown) through a gear belt pair 700; they are driven and connected to a master control motor through the gear belt pair 700, thereby achieving synchronous transportation of the cardboard feed roller group 200, the laminating feed roller group 300, and the longitudinal cutting assembly 500, ensuring the consistency of the overall transportation speed and improving the collaborative working efficiency of the mechanism.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
