Description

Technical Field

[0001] This utility model relates to the technical field of corrugated paper composite devices, specifically a multi-layer corrugated paper composite device for manufacturing cartons. Background Technology

[0002] Corrugated cardboard is a common material for paper packaging boxes. It is lighter than wooden boxes, yet rigid, and easy to cut to size. It protects other packaged products from damage and is one of the most widely used packaging products, consistently ranking first in usage among all packaging products. Corrugated cardboard is made into corrugated boxes through die-cutting, creasing, and stapling or gluing. The production process of corrugated cardboard requires the bonding and lamination of the corresponding paper materials.

[0003] For example, Chinese Patent CN217073701U discloses a device for laminating multi-layer corrugated cardboard, which includes an outer frame. The left and right ends of the frame wall of the outer frame are provided with grooves. The inner wall of the groove is provided with a square through hole that passes through the inner wall of the outer frame. A movable plate is provided in the groove. A pull ring and a glue bottle are provided on the left side of the movable plate. A thin sheet is provided on the right side of the movable plate. A glue outlet hole is provided in the thin sheet. A through groove for dispensing glue is provided in the movable plate. An extension piece is provided on the bottom surface of the outer frame. The device also includes a cover assembly, which consists of a cover plate and a pressure plate. The pressure plate is located on the lower surface of the cover plate. An insert rod is provided on the edge of the cover plate. The device in this application limits the corrugated cardboard by using an outer frame and an extension plate to prevent misalignment, thus solving the problem of misalignment during lamination in traditional devices. It uses an automatic glue dispensing method to bond the placed cardboard, avoiding contact between the human body and the glue and reducing the risk of worker illness. However, traditional paper sheets are prone to shifting during the conveying process, affecting the accuracy of the lamination process. Therefore, a multi-layer corrugated paper lamination device for manufacturing cartons is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-layer corrugated paper composite device for manufacturing cardboard boxes, which has advantages such as increasing the accuracy of paper sheet conveying and solving the problem of deviations that easily occur in traditional paper sheet conveying processes.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned goal of increasing the accuracy of paper sheet conveying, this utility model provides the following technical solution: a multi-layer corrugated paper composite device for manufacturing cartons, comprising a frame, wherein guide rollers, a second pressure shaft and a first pressure shaft are sequentially installed horizontally inside the frame, and two sets of guide rollers, second pressure shafts and first pressure shafts are arranged vertically; a mounting frame is fixedly installed at one end of the first pressure shaft and the second pressure shaft at the top of the frame, and one end of the first pressure shaft and the second pressure shaft is rotatably connected to the mounting frame;

[0008] The guide frame is fixedly installed at the top of the frame. The bottom end of the guide frame corresponds to the position between the two sets of second pressure shafts. The outer surface of the guide frame is provided with a baffle assembly, which positions the paper sheet during feeding.

[0009] Preferably, a gear transmission group is provided at one end of the second pressure shaft and the first pressure shaft. The gear transmission group drives the upper and lower sets of the second pressure shaft and the first pressure shaft to rotate and enter the second pressure shaft and the first pressure shaft for composite processing. The first pressure shaft and the second pressure shaft are rotated and pressed together by the gear transmission group at one end.

[0010] Preferably, the baffle assembly includes two sets of baffles disposed on the inclined surface of the guide frame, and the baffles are L-shaped.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 The present invention provides the following technical solution: a multi-layer corrugated paper composite device for manufacturing cartons, comprising a frame 1, wherein guide rollers 11, a second pressure shaft 13 and a first pressure shaft 12 are sequentially installed horizontally inside the frame 1, and two sets of guide rollers 11, second pressure shafts 13 and first pressure shafts 12 are arranged vertically. A mounting frame 15 is fixedly installed at one end of the first pressure shaft 12 and the second pressure shaft 13 at the top of the frame 1, and one end of the first pressure shaft 12 and the second pressure shaft 13 is rotatably connected to the mounting frame 15.

[0024] In this embodiment, a gear transmission group 14 is provided at one end of the second pressure shaft 13 and the first pressure shaft 12. The gear transmission group 14 drives the upper and lower sets of the second pressure shaft 13 and the first pressure shaft 12 to rotate and enter the second pressure shaft 13 and the first pressure shaft 12 for composite processing. The first pressure shaft 12 and the second pressure shaft 13 are rotated and pressed together by the gear transmission group 14 at one end.

[0025] In this embodiment, the guide frame 2 is fixedly installed on the top of the frame 1. The bottom end of the guide frame 2 corresponds to the position between the two sets of second pressure shafts 13. The outer surface of the guide frame 2 is provided with a baffle assembly, which positions the paper sheet during feeding.

[0026] The baffle assembly includes two sets of baffles 23 disposed on the inclined surface of the guide frame 2. The baffles 23 are L-shaped. The outer surfaces of the two sets of baffles 23 are transversely passed through the guide rods 21. The outer surface of the guide frame 2 is fixedly installed with fixing seats 22 at both ends of the guide rods 21. When the paper passes through the guide frame 2, it will be limited by the baffles 23 on both sides to prevent deviation during the conveying process.

[0027] In this example, a pressure roller 24 is fitted on the outer surface of the guide frame 2 inside the baffle 23, and one side of the baffle 23 is rotatably connected to the inner wall of the baffle 23. The pressure roller 24 presses and flattens the edge of the paper sheet, thereby increasing the effect after lamination.

[0028] The guide rod 21 has an adjusting tube 25 fitted on its outer surface, and one end of the adjusting tube 25 is fixedly connected to the outer surface of the baffle 23. A limiting rod 26 is inserted into the top of the adjusting tube 25 and is threadedly connected to the adjusting tube 25. The outer surface of the guide rod 21 has several limiting grooves 27 that match the bottom end of the limiting rod 26. By rotating the limiting rod 26 on the adjusting tube 25, the bottom end of the limiting rod 26 is disengaged from the limiting groove 27, releasing the limiting effect on the adjusting tube 25. Then, the adjusting tube 25 is slid along the guide rod 21 to adjust the distance between the baffle 23 and the pressure roller 24.

[0029] The working principle of this embodiment is as follows:

[0030] In use, the bottom corrugated cardboard structure is conveyed by the guide roller 11 inside the frame 1, and the top paper sheet is conveyed by the guide frame. Then, it enters the second pressure shaft 13 and the first pressure shaft 12 for composite processing. The first pressure shaft 12 and the second pressure shaft 13 are rotated and pressed together by a gear transmission group 14 at one end.

[0031] As the paper sheet passes through the guide frame 2, it is limited by the baffles 23 on both sides to prevent deviation during the conveying process. At the same time, the pressure rollers 24 press and flatten the edges of the paper sheet to enhance the effect after lamination. When it is necessary to adjust the spacing between the baffles 23 according to the width of the paper sheet, the limiting rod 26 on the adjusting tube 25 can be rotated to disengage the bottom end of the limiting rod 26 from the limiting groove 27, thereby releasing the limitation on the adjusting tube 25. Then, the adjusting tube 25 can be slid along the guide rod 21 to adjust the spacing between the baffles 23 and the pressure rollers 24.
