Description

Technical Field

[0001] This utility model belongs to the technical field of corrugated paper slotting machine, specifically relating to the feeding and slotting mechanism of a corrugated cardboard slotting machine. Background Technology

[0002] In the corrugated paper production process, the creasing roller plays a crucial role. It is used to roll a clear line (i.e., groove) on the cardboard and then transfer the creasing cardboard to another pair of shafts for cutting. The groove is designed to facilitate bending of the cardboard at specific positions. It is an indispensable part of making cartons. The creasing roller not only ensures the aesthetics of the cartons, but also guarantees their stability and durability in practical applications. It is an indispensable link in the processing of corrugated paper products.

[0003] The existing feeding and slotting mechanisms have a large shaft diameter, resulting in a relatively large distance between the slotting knife and the creasing wheel. This limits their ability to process smaller cardboard and cannot meet the growing market demand for small cartons. In order to meet the production needs of small cartons, it may be necessary to purchase additional equipment adapted to small cardboard, which will undoubtedly increase the company's production costs and operational burden. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding and slotting mechanism for a corrugated cardboard slotting machine, so as to solve the problem mentioned in the background art that the existing feeding and slotting mechanisms have a large shaft diameter and cannot process small cardboard.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding and slotting mechanism for a corrugated cardboard slotting machine, including a linkage plate; two cutter discs, arranged vertically, with the upper cutter disc positioned on one side of the bottom of the linkage plate, and the diameter of the upper cutter disc generally larger than that of the lower cutter disc; and a creasing assembly, which consists of two creasing sections with unequal diameters, the upper creasing section positioned on the linkage plate, and the diameter of the upper creasing section smaller than that of the lower creasing section. By reducing the diameter of the upper creasing section, the creasing section can be made closer to the cutter disc, thereby enabling the processing of small cartons;

[0006] A pre-pressing component is also installed at the bottom of the linkage plate, and the pressing part is located between the pre-pressing component and the cutter head.

[0007] Preferably, the pressing part includes a pressing wheel disposed at the bottom of the linkage plate and a hexagonal steel sleeved on the pressing wheel. The longitudinal section of the hexagonal steel is a regular hexagon. The pressing wheel drives the hexagonal steel to rotate, and the hexagonal steel then transmits the pressed paper to the position of the guide plate for corresponding cutting processing.

[0008] Preferably, the surface of the linkage plate is provided with multiple mounting holes, and a through hole is provided on the side of each mounting hole. During installation, other shaft structures required for multiple slots will be installed with the mounting holes. Since the structure in this area is existing technology and is not related to the improvement of this utility model, it will not be described in detail here. Annular grooves are provided at both ends of the through holes. A retaining ring is placed inside the annular groove. A retaining protrusion is fixed at an equal angle on the outer surface of the retaining ring. An elastic element is also provided between the retaining ring and the annular groove. The elastic element can push the retaining ring and the retaining protrusion outward, so that the retaining protrusion abuts against the end face of the nut used for the connecting shaft, preventing the nut from loosening.

[0009] Preferably, the elastic element is a spring, and a limiting ring is screwed into the opening of the annular groove. The limiting ring abuts against the outer surface of the abutting ring, thereby limiting the abutting ring and preventing the abutting ring from separating directly from the annular groove.

[0010] Preferably, the inner diameters of the clamping ring and the spring are both larger than the inner diameter of the mounting hole, and the clamping protrusion extends to the outside of the ring groove.

[0011] Preferably, the pre-pressing component includes a pre-pressing shaft disposed at the bottom corner of the linkage plate, and a pre-pressing wheel is also sleeved on the pre-pressing shaft. The pre-pressing shaft drives the pre-pressing wheel to rotate, thereby pre-pressing the paper and transferring it to the position of the pressing wheel.

[0012] Preferably, the longitudinal section of the abutting protrusion is an irregular quadrilateral, and the abutting protrusion has at least one inclined side, which abuts against the end face of the outer nut.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By reducing the diameter of one shaft based on the original model, the distance between the grooving knife and the creasing wheel is reduced. The reduced distance means that smaller cardboard can be used, allowing the equipment to adapt to the requirements of more small cartons. Attached Figure Description

The diameter of the cutter head 101 in the upper position is generally larger than that of the cutter head 101 in the lower position.

[0027] It also includes a creasing assembly, which consists of two creasing sections with different diameters. The upper creasing section is located on the linkage plate 100, and its diameter is smaller than that of the lower creasing section. By reducing the diameter of the upper creasing section, it can be brought closer to the cutter head 101, thereby enabling the processing of small cartons. For details, please refer to [reference needed]. Figure 4 and Figure 5 When a small-diameter pressing part is used, the distance between it and the cutter head 101 is d2, while the distance between the pressing part without a small diameter and the cutter head 101 is d1. The distance d1 is significantly greater than d2. Therefore... Figure 4 The state shown in the diagram presents inconveniences when cutting small-volume cardboard boxes.

A retaining protrusion 108 is fixed at an equal angle on the outer surface of the retaining ring 109. An elastic element is also provided between the retaining ring 109 and the annular groove 106. The elastic element can push the retaining ring 109 and the retaining protrusion 108 outward, so that the retaining protrusion 108 abuts against the end face of the nut used for the connecting shaft, preventing the nut from loosening.

[0031] In this embodiment, preferably, the elastic element is a spring 110, and a limiting ring 107 is screwed into the opening of the annular groove 106. The limiting ring 107 abuts against the outer surface of the abutting ring 109, thereby limiting the abutting ring 109 and preventing the abutting ring 109 from separating directly from the annular groove 106.

[0032] In this embodiment, preferably, the inner diameters of the clamping ring 109 and the spring 110 are both larger than the inner diameter of the mounting hole 104, and the clamping protrusion 108 protrudes to the outside of the ring groove 106.
