Description

Technical Field

[0001] This utility model belongs to the field of corrugated cardboard processing technology, specifically relating to a gluing device for corrugated cardboard used in environmentally friendly corrugated cardboard boxes. Background Technology

[0002] Corrugated cardboard is a multi-layered bonded material, consisting of at least one corrugated core and a linerboard. It possesses high mechanical strength and cushioning capabilities, allowing it to withstand impacts and drops during handling. It is widely used in the manufacture of corrugated boxes. During the bonding process, a gluing device applies glue to the surface of the linerboard. Most existing gluing devices consist of a gluing roller and a glue tank. The lower part of the gluing roller is immersed in the glue tank containing adhesive, while the linerboard wraps around the upper part of the roller. The subsequent rotation of the roller spreads the adhesive it carries onto the cardboard. The gluing process is simple and easy. However, during the actual operation, the glue residue on the surface of the gluing roller is not effectively filtered after gluing and is directly recycled back into the glue tank. This can easily cause contamination of the glue tank due to debris or impurities mixed in with the residual glue, affecting subsequent gluing operations. Therefore, to solve the above problems, it is necessary to develop an environmentally friendly gluing device for corrugated cardboard boxes that has a reasonable structural design and is easy to install and adjust. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an environmentally friendly coating device for corrugated cardboard boxes that has a reasonable structural design and is easy to install and adjust.

[0004] The purpose of this utility model is achieved as follows: A gluing device for corrugated cardboard boxes made of environmentally friendly corrugated paperboard includes a glue tank body and a drive motor. The glue tank body is a groove-shaped structure with an opening at the top. A glue roller is longitudinally arranged on the left end of its upper surface, and a filter assembly is longitudinally arranged on the right end of its upper surface. The lower end of the glue roller is located inside the glue tank body. Both the front and rear ends of the glue roller are rotatably connected to fixed supports via rotating shafts, and the lower ends of the fixed supports are fixedly connected to the upper surface of the glue tank body. The drive motor is located outside the fixed support at the front end of the glue roller and is concentrically fixedly connected to the glue roller. The filter assembly includes strip-shaped connecting blocks, a filter plate, a scraper, an electric adjusting rod, and a control box. There are two strip-shaped connecting blocks, both longitudinally fixedly arranged at the top of the glue tank body, and the inner surfaces of the strip-shaped connecting blocks... A through groove is provided in the middle of the filter plate along its length. The filter plate is located between two strip-shaped connecting blocks. Both sides of the filter plate are fixedly provided with locking blocks. Through the cooperation of the locking blocks and the through groove, the filter plate can be longitudinally slidably installed between the two strip-shaped connecting blocks. The scraper is inclined and located at the upper end of the filter plate. One side of the scraper is in contact with the outer surface of the upper glue roller. The front and rear ends of the other side are rotatably connected to the mounting blocks, and the mounting blocks are fixedly connected to the filter plate. There are two electric adjusting rods, located at the front and rear ends between the filter plate and the scraper, respectively. The upper end of the electric adjusting rod is hinged to the support a, and the lower end is hinged to the support b. The support a is fixedly connected to the end face of the scraper, and the support b is fixedly connected to the end face of the filter plate. The control box is fixedly installed on the right side of the glue tank body, and the electric adjusting rod is electrically connected to the control box through a wire.

[0005] Furthermore, a transparent liquid level observation frame is vertically provided in the middle of the front end face of the glue tank body.

[0006] Furthermore, the card block is made of iron, and an electromagnet is longitudinally fixed at the lower end of the through groove, and the electromagnet is electrically connected to the control box through a wire.

[0007] Furthermore, the upper surface of the scraper is provided with multiple guide grooves in the transverse direction.

[0008] The beneficial effects of this utility model are as follows: By setting a fixed bracket and a drive motor, the fixed bracket can be used to limit the installation of the glue roller on the left side of the upper surface of the glue tank body, and the drive motor can drive the glue roller to rotate, thereby performing a glue application operation on the paper passing through its upper end through the rotation of the glue roller.

[0009] By setting up strip connecting blocks, through grooves, filter plates, and locking blocks, the filter plates can be longitudinally slidably installed between two strip connecting blocks using the cooperation of the locking blocks and through grooves. By setting up scrapers, mounting blocks, electric adjusting rods, supports a and b, the mounting blocks can be used to limit the installation of the scraper above the filter plates. Utilizing the telescopic nature of the electric adjusting rod, the hinges between the two ends of the electric adjusting rod and supports a and b respectively, and the rotatable connection between the scraper and the mounting blocks, the tilt angle of the scraper can be adjusted by adjusting the extended length of the electric adjusting rod during use, so that its side is flush with the outer surface of the upper rubber roller. By using close contact, the scraper can remove residual adhesive from the surface of the glue roller after gluing by rotating it. The scraped adhesive is then filtered by a filter plate under the guidance of the scraper and flows back into the glue tank. This structure reduces waste by filtering and recycling residual adhesive from the glue roller surface, and also avoids problems caused by impurities mixed in with the residual adhesive affecting subsequent gluing operations. Overall, this invention has the advantages of reasonable structural design and convenient installation and adjustment. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Example: Figure 1 , Figure 2 , Figure 3As shown, an adhesive coating device for corrugated cardboard boxes made of environmentally friendly corrugated paperboard includes an adhesive tank body 1 and a drive motor 2. The adhesive tank body 1 is a groove-shaped structure with an opening at the top. An upper adhesive roller 3 is longitudinally arranged at the left end of its upper surface, and a filter assembly 4 is longitudinally arranged at the right end of its upper surface. The lower end of the upper adhesive roller 3 is located inside the adhesive tank body 1. The front and rear ends are rotatably connected to fixed brackets 31 via rotating shafts, and the lower ends of the fixed brackets 31 are fixedly connected to the upper surface of the adhesive tank body 1. The drive motor 2 is located outside the fixed brackets 31 at the front end of the upper adhesive roller 3 and is concentrically fixedly connected to the upper adhesive roller 3. The filter assembly 4 includes a strip connecting block 41, a filter plate 42, a scraper 43, an electric adjusting rod 44, and a control box 45. There are two strip connecting blocks 41, both of which are longitudinally fixedly arranged at the top of the adhesive tank body 1, and a through groove 411 is provided in the middle of the inner side of the strip connecting block 41 along its length direction. The filter plate 42 is located between two strip-shaped connecting blocks 41, and a locking block 46 is fixedly installed on both sides of it. Through the cooperation of the locking block 46 and the through groove 411, it can be longitudinally slidably installed between the two strip-shaped connecting blocks 41. The scraper 43 is inclined and located at the upper end of the filter plate 42. One side of it is in contact with the outer surface of the upper glue roller 3, and the front and rear ends of the other side are rotatably connected to the mounting block 47, and the mounting block 47 is fixedly connected to the filter plate 42. There are two electric adjusting rods 44, located at the front end and rear end between the filter plate 42 and the scraper 43, respectively. The upper end of the electric adjusting rod 44 is hinged to the support a48, and the lower end is hinged to the support b49. The support a48 is fixedly connected to the end face of the scraper 43, and the support b49 is fixedly connected to the end face of the filter plate 42. The control box 45 is fixedly installed on the right side of the glue tank body 1, and the electric adjusting rod 44 is electrically connected to the control box 45 through a wire.

[0016] A transparent liquid level observation frame 11 is vertically arranged in the middle of the front end face of the glue tank body 1. The transparent liquid level observation frame 11 can be used to easily observe and judge the amount of glue liquid inside the glue tank body 1. The locking block 46 is made of iron. An electromagnet 412 is vertically fixed in the lower end of the through groove 411. The electromagnet 412 is electrically connected to the control box 45 through a wire. The magnetic attraction of the electromagnet 412 to the iron locking block 46 after it is energized can realize the limiting connection between the filter plate 42 and the strip connecting block 41. Multiple guide grooves 431 are arranged horizontally on the upper surface of the scraper 43.

[0017] Before use, the filter plate 42 needs to be installed with a limiting position and the scraper 43 needs to be adjusted in angle. The specific operation is as follows: First, using the cooperation of the locking block 46 and the through groove 411, the filter plate 42 is slidably installed longitudinally between the two strip connecting blocks 41. Then, the energizing circuit of the electromagnet 412 is turned on through the control box 45. At this time, the magnetic attraction of the electromagnet 412 to the iron locking block 46 after being energized can realize the limiting connection between the filter plate 42 and the strip connecting block 41. This structure can increase the stability of the connection between the filter plate 42 and the strip connecting block 41 and avoid subsequent problems. During use, the longitudinal movement of the filter plate 42 affects its performance. Then, the extension length of the electric adjusting rod 44 is adjusted via the control box 45. At this time, by utilizing the hinges between the two ends of the electric adjusting rod 44 and supports a48 and b49 respectively, and the rotational connection between the scraper 43 and the mounting block 47, the extension length of the electric adjusting rod 44 can be adjusted while simultaneously adjusting the tilt angle of the scraper 43, ensuring that the outer side of the scraper 43 is in close contact with the outer surface of the upper rubber roller 3. Thus, the installation of the filter plate 42 and the angle adjustment of the scraper 43 are completed.

[0018] In use, this invention first turns on the drive motor 2, which rotates the gluing roller 3 clockwise. During this rotation, the glue adsorbed on its surface by the glue tank body 1 applies glue to the paper passing above it. After gluing, as the roller continues to rotate, the scraper 43 removes any remaining glue. Guided by the scraper 43 and its surface guide groove 431, the scraped glue flows to the top of the filter plate 42, where it is filtered before flowing back into the glue tank body 1. This structure reduces waste by filtering and recovering the glue remaining on the roller 3, and also prevents contamination of the glue tank body 1 by impurities in the recovered glue, thus avoiding problems with subsequent gluing operations. Overall, this invention has the advantages of a reasonable structural design and convenient installation and adjustment.
