Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard feeding technology, and in particular to a corrugated cardboard top-feeding multi-compartment feeding device. Background Technology

[0002] Cardboard boxes are the most widely used packaging products, and packaging cardboard boxes are an indispensable part of modern logistics. Commonly used packaging cardboard boxes mainly use corrugated cardboard boxes and single-layer cardboard boxes. Both corrugated cardboard boxes and single-layer cardboard boxes are formed by cutting and creasing cardboard, then folding and gluing them together to form the box shape.

[0003] Corrugated cardboard is a type of board material composed of a corrugated core layer and a cover layer formed between two or more layers of cardboard. The corrugated core layer is corrugated, and the corrugations are connected in rows and support each other to form a triangular structure, which has good mechanical strength and can withstand a certain amount of pressure on a flat surface. In the current production process, corrugated cardboard needs to undergo creasing and cutting. Creeping is mostly done by using creasing equipment to crease the surface of the cardboard to create fold lines, which facilitates subsequent folding to form cartons. After creasing, the corrugated cardboard can be stacked along the creases. Cutting involves feeding the creasing corrugated cardboard into a cutting station for processing, so that long corrugated cardboard can be cut into profiles of the required length. However, before entering the cutting equipment, the stacked corrugated cardboard needs to be unfolded.

[0004] To increase rigidity, existing corrugated cardboard production uses multiple layers of cardboard stacked together, resulting in thicker corrugated cardboard. However, this thickness adds weight, making it difficult for paper cutters to move the thicker cardboard during feeding, thus affecting feeding efficiency. Furthermore, pulling heavy cardboard can damage it, and unfolding it can easily cause creases, and in severe cases, even breakage or deformation. Using conveyor belts to transport the cardboard increases production costs and requires manual handling to place and flatten the stacked cardboard on the conveyor belt, ensuring it enters the cutting machine straight. Feeding multi-compartment stacks of cardboard also requires multiple people working simultaneously, resulting in low efficiency.

[0005] Therefore, how to unfold and transport stacked corrugated cardboard is the main technical problem that technicians need to solve. Utility Model Content

[0006] The purpose of this utility model is to provide a corrugated cardboard top-feeding multi-compartment paper feeding device. The strip plate on the rotating part corresponds to the cardboard indentation, supporting and pushing the cardboard forward. The strip groove formed by the limiting plate and the supporting plate ensures that the cardboard is output smoothly and in a straight line when unfolded. It is suitable for corrugated cardboard of different thicknesses and widths. It has a simple structure, low cost and strong adaptability.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a corrugated cardboard top-feed multi-compartment paper feeding device, comprising: Mounting rod assembly and several support shafts; Several support shafts are located on the top of the mounting rod assembly, and several rotating parts are provided on the outside of each support shaft. Several extensions are provided on the outside of each rotating part, and strip-shaped support plates are provided at the ends of the extensions. The center distance of the strip-shaped support plates to the rotating parts is the same, and the strip-shaped support plates correspond to the indentations of the corrugated cardboard. The mounting rod assembly is also equipped with a support cross plate, and a limiting cross plate is provided on the outside of the support cross plate. The limiting cross plate and the side opposite to the support cross plate form a strip groove, which is used for the output of unfolded corrugated cardboard.

[0008] Preferably, a plurality of rotating components are provided with mounting through holes at their centers, and a plurality of supporting shafts are provided with rotating bearings on their exteriors, with the mounting through holes fitted onto the exteriors of the rotating bearings.

[0009] Preferably, a plurality of guide baffles are slidably provided on the outside of the supporting horizontal plate. The tops of the plurality of guide baffles are inclined and close to the bottom of the rotating member, and one side of the plurality of guide baffles faces the limiting horizontal plate.

[0010] Preferably, when the corrugated cardboard is on top of the rotating component, both adjacent strip trays are located at the bottom of the corrugated cardboard, and the spacing between the two adjacent strip trays is the same as the indentation spacing of the corrugated cardboard.

[0011] Preferably, a transverse guide rail is provided on the top of the support plate, the transverse guide rail extends along the length of the support plate, and a movable roller is provided on the outside of the guide baffle, the movable roller being slidably connected to the transverse guide rail.

[0012] Preferably, several of these support shafts are evenly distributed on the top of the mounting rod assembly along the discharge direction of the corrugated cardboard.

Several extensions extend from the exterior of each rotating part, and strip-shaped support plates are provided at the ends of these extensions. The distances from these strip-shaped support plates to the center of the rotating parts are equal, and the strip-shaped support plates correspond to the indentations of the corrugated cardboard. During the corrugated cardboard conveying process, the strip-shaped support plates of the rotating parts provide support for the corrugated cardboard, and the rotation of the rotating parts facilitates the movement and conveying of the corrugated cardboard. During the process, the strip pallet supports the indentation of the corrugated cardboard, ensuring that the corrugated cardboard remains in an unfolded state for conveying. A support crossplate is also installed on the mounting rod assembly, and a limiting crossplate is installed on the outside of the support crossplate, so that the opposite side of the limiting crossplate and the support crossplate forms a strip groove. The strip groove is adapted to the thickness of the corrugated cardboard, allowing the unfolded corrugated cardboard to be output through the strip groove, ensuring that the corrugated cardboard is conveyed straight. This utility model has a simple structure and can effectively unfold and convey stacked corrugated cardboard, keeping it straight and preventing friction damage caused by excessive contact area. It allows thicker corrugated cardboard to smoothly enter subsequent processing stations, reducing production costs while saving time and labor. Attached Figure Description

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0031] Example 1: To achieve smooth unfolding and conveying of stacked corrugated cardboard, existing corrugated cardboard requires sequential creasing and cutting during production. After creasing, it is stacked for transport. Therefore, when entering the cutting machine, the stacked corrugated cardboard needs to be unfolded sequentially, and the cardboard must be kept from deformation during unfolding. To solve this technical problem, this example: A mounting rod assembly 1 and several support shafts 2 are provided. The support shafts 2 are all located at the top of the mounting rod assembly 1. Each support shaft 2 has several rotating parts 3 on its exterior. Several extensions are provided on the exterior of each rotating part 3. Strip trays 31 are provided at the ends of these extensions. The center distances of the strip trays 31 to the rotating parts 3 are the same, and the strip trays 31 correspond to the creasing marks on the corrugated cardboard. During the corrugated cardboard conveying process... During the process, the strip pallet 31 of the rotating component 3 supports the corrugated cardboard, and the rotation of the rotating component 3 facilitates the movement and conveying of the corrugated cardboard. During the movement and conveying of the corrugated cardboard, the strip pallet 31 supports the indentations of the corrugated cardboard, ensuring that the corrugated cardboard is conveyed in an unfolded state. A support cross plate 4 is also provided on the mounting rod assembly 1, and a limiting cross plate 5 is provided on the outside of the support cross plate 4, so that the limiting cross plate 5 and the opposite side of the support cross plate 4 form a strip groove 6, and the strip groove 6 is adapted to the thickness of the corrugated cardboard. The strip groove 6 can be used for the output of unfolded corrugated cardboard, ensuring that the corrugated cardboard is conveyed straight. This utility model has a simple structure and can effectively unfold and convey stacked corrugated cardboard, keeping the corrugated cardboard straight and preventing friction damage caused by excessive contact area, so that thicker corrugated cardboard can enter the subsequent processing station smoothly.

[0032] It should be noted that the center of the rotating part 3 is provided with an installation through hole, and it is rotatably connected to the support shaft part 2 through the rotating bearing 21. At least three extensions are evenly fixed on the outer periphery of each rotating part 3. A strip-shaped support plate 31 is vertically engaged at the end of each extension. The distance from the strip-shaped support plate 31 to the center of the rotating part 3 is the same. The spacing between two adjacent strip-shaped support plates 31 is consistent with the preset indentation spacing on the corrugated cardboard. When the corrugated cardboard is on top of the rotating part 3, the two adjacent strip-shaped support plates 31 can support the two indentations of the corrugated cardboard, so that it can be fully unfolded and transported smoothly.

[0033] It should also be noted that the limiting plate 5 can be movably positioned outside the supporting plate 4, so that one side of the limiting plate 5 is opposite to one side of the supporting plate 4. Since the opposite sides of the limiting plate 5 and the supporting plate 4 form a strip groove 6, this strip groove 6 is used for corrugated cardboard discharge. The width of the strip groove 6 can be adjusted by adjusting the distance between the limiting plate 5 and the supporting plate 4 to accommodate corrugated cardboard of different thicknesses for conveying, ensuring that the corrugated cardboard remains straight during the output process and does not shift in position.

[0034] In this embodiment, it should be noted that when cutting the corrugated cardboard after creasing, the ends of the corrugated cardboard need to be placed in the cutting machine, and the corrugated cardboard is driven into the cutting station by the conveying part of the cutting machine. During this process, the corrugated cardboard can be moved. With the structure of this embodiment, it can be ensured that the stacked corrugated cardboard unfolds in sequence and moves smoothly to prevent deformation and damage.

[0035] It should also be noted that the top of the strip pallet 31 is set with an arc-shaped structure to ensure that the surface of the corrugated cardboard will not be damaged when the strip pallet 31 comes into contact with the indentation of the corrugated cardboard.

[0036] Example 2: To achieve smooth guiding of corrugated cardboard with different widths, since existing corrugated cardboard has different sizes, this example further optimizes the structure of the guide baffle 41 based on Example 1, making it position-adjustable to adapt to corrugated cardboard of different widths for guiding and discharging. In this example: a movable roller 411 can be installed on the outside of each guide baffle 41. The movable roller 411 slides with the transverse guide rail 22 on the support plate 4. By pushing the guide baffle 41 to move along the transverse guide rail 22, it can adapt to the discharging and guiding of corrugated cardboard of different widths.

[0037] In addition, the inclined structure at the top of the guide baffle 41 ensures that the unfolded corrugated cardboard enters the strip groove 6 to prevent the edges of the corrugated cardboard from curling up or folding. It can be quickly adjusted to accommodate different cardboard sizes without disassembly.

[0038] In this embodiment, it should be noted that, for ease of installation and disassembly, the mounting rod assembly 1 can be made of several connecting rods connected by bolts. Each connecting rod has multiple holes for fixing the support shaft 2 and the support cross plate 4.

[0039] In Example 3, to achieve continuous material supply to the cutting machine from multiple compartments, i.e., to simultaneously transport stacked corrugated cardboard from multiple compartments via multiple conveying paths, in this example: several support shafts 2 can be arranged side by side on the mounting rod assembly 1, so that several rotating parts 3 on the side by side support shafts 2 are aligned one by one. The aligned rotating parts 3 can form a conveying path for stacking corrugated cardboard in different compartments. Each compartment can independently stack a stack of corrugated cardboard. When feeding corrugated cardboard to the cutting machine, the cutting machine drives one end of the stacked corrugated cardboard, so that the corrugated cardboard moves smoothly on the rotating block. During the movement, the strip support plate 31 on the rotating block abuts against the indentation of the corrugated cardboard, ensuring that the corrugated cardboard is fully unfolded, so as to achieve uninterrupted supply of corrugated cardboard to the cutting machine and improve production efficiency.

[0040] In combination with the above embodiments, this utility model has a simple overall structure and low cost, does not require a complex conveyor belt or motor drive system, and can be applied to corrugated cardboard with different thicknesses, widths and creasing spacings; the conveying is stable, the strip pallet 31 supports the creasing correspondingly, avoiding deformation or damage to the cardboard; it can continuously feed materials to the cutting machine, supports multi-compartment stacking conveying, and improves production efficiency.

Furthermore, it is understood that the steps in the method of the present invention embodiments can be adjusted, combined, and deleted according to actual needs, and the structure in the device of the present invention embodiments can be combined, divided, and deleted according to actual needs.
