Description

Technical Field

[0001] This utility model belongs to the field of honeycomb paperboard processing technology, specifically relating to an adhesive applicator for honeycomb paperboard manufacturing equipment. Background Technology

[0002] Honeycomb paperboard is an environmentally friendly and energy-saving material made based on the honeycomb structure principle found in nature. It is composed of two layers of face paper and a honeycomb core bonded together using an adhesive process. The honeycomb core is made by bonding multiple layers of paper or paperboard together with adhesive, followed by a stretching process to form a continuous, honeycomb-shaped core material. During the manufacturing process, adhesive is applied to the surface of the core using gluing equipment within the honeycomb paperboard manufacturing apparatus, so that the face paper and other paper components can be subsequently bonded to the core.

[0003] Patent CN214864913U discloses "a honeycomb cardboard conveying and gluing device, including a glue container and a feeding mechanism connected to it. Since the glue in the container gradually decreases during use, to avoid manual high-frequency glue addition in a short period of time, a larger volume of glue is pre-set in the feeding chamber. The cooperation between the drive component and the baffle allows the baffle to intermittently block the guide pipe, enabling the guide pipe to intermittently feed the glue container, effectively avoiding manual glue addition, reducing the frequency of glue addition, and making it more conducive to the automated production of cardboard gluing."

[0004] Although the glue can be applied to the paper core by rotating the glue roller as described in the above document, the glue is quite viscous, which makes it easy for the glue to be applied too thickly to the outer surface of the glue roller. Applying too thick a layer of glue to the paper core will increase glue waste and make it impossible to control the amount of glue applied to the paper core. Therefore, this needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide an adhesive applicator for a honeycomb paperboard manufacturing apparatus in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A gluing device for a honeycomb paperboard manufacturing apparatus includes a glue container, a gluing roller rotatably disposed within the glue container, a pressure roller mounted on the top of the glue container and directly above the gluing roller, and a glue scraping mechanism disposed within the glue container. The glue scraping mechanism includes a second electric push rod fixedly disposed on the top inner side of the glue container, and a scraper fixedly disposed on one end of the second electric push rod for scraping off excess glue from the surface of the gluing roller. A U-shaped rod is fixedly disposed on one side of the scraper, and the gluing roller is located inside the U-shaped rod. A first cleaning component is fixedly disposed on the inner side of the U-shaped rod for cleaning the gluing roller by pressing against the outer surface of the gluing roller after the second electric push rod is continuously shortened.

[0008] As a further optimization of this utility model, a first motor for driving the glue roller to rotate is fixedly installed on the outer wall of the glue container, and an electric heating element is fixedly installed on the bottom of the inner wall of the glue container.

[0009] As a further optimization of this utility model, a fixing frame is fixedly provided on the top of the glue container, and a first electric push rod is fixedly provided on the top inner side of the fixing frame.

[0010] As a further optimization of this utility model, a connecting frame is fixedly installed at the bottom end of the first electric push rod, and the pressure roller is rotatably connected inside the connecting frame.

[0011] As a further optimization of this utility model, a second motor for driving the pressure roller to rotate is fixedly installed at one end of the connecting frame.

[0012] As a further optimization of this utility model, a vertical rod is fixedly provided on the top inner side of the fixing frame, a horizontal bar is fixedly provided at the bottom end of the vertical rod, and a second cleaning component is fixedly provided at the bottom of the horizontal bar for cleaning the outer surface of the upward-moving pressure roller after the first electric push rod continues to shorten.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The scraper can remove excess or thick adhesive from the surface of the gluing roller. The scraped adhesive will fall into the glue collection box for reuse, thereby reducing glue waste. The extension and retraction of the second electric push rod will drive the scraper to move, making it easy to control the amount of glue applied to the paper core by adjusting the scraping distance of the scraper. After the second electric push rod continues to shorten, it will press the first cleaning component against the gluing roller, making it easy to clean the outer surface of the rotating gluing roller with the first cleaning component, reducing the cleaning intensity of the gluing roller by the staff later.

[0015] 2. The pressure roller presses the paper core onto the top of the gluing roller during gluing, allowing the paper core to fully contact the glue on the surface of the gluing roller, which facilitates gluing. The extension and retraction of the first electric push rod controls the height of the pressure roller, making it easier for the pressure roller and gluing roller to apply glue to paper cores of different thicknesses. As the first electric push rod continues to shorten, it will drive the pressure roller to move upward. The second cleaning component can clean the outer surface of the pressure roller after it moves upward and rotates, reducing the cleaning intensity of the pressure roller for the staff later.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] like Figure 1-3 As shown, the gluing device for a honeycomb paperboard manufacturing apparatus includes a glue container 1, a glue roller 2, a pressure roller 3, and a glue scraping mechanism. The glue container 1 can hold glue. The gluing device composed of the glue container 1 and other components can be installed on an existing honeycomb paperboard manufacturing apparatus to apply glue to the paper core and other paper bodies of the honeycomb paperboard.

[0023] like Figure 1-3 As shown, the gluing roller 2 is rotatably mounted inside the glue container 1, and the pressure roller 3 is installed on the top of the glue container 1 and located directly above the gluing roller 2. In use, paper cores and other paper bodies are inserted between the gluing roller 2 and the pressure roller 3. After the gluing roller 2 rotates, it will apply glue from the glue container 1 to the bottom of the paper cores and other paper bodies. The pressure roller 3 can press the paper cores and other paper bodies onto the top of the gluing roller 2 during gluing, so that the paper cores can fully contact the glue on the surface of the gluing roller 2, which is convenient for gluing.

[0024] like Figure 1-2 As shown, a first motor 21 for driving the glue roller 2 to rotate is fixedly installed on the outer wall of the glue container 1, and an electric heating element 11 is fixedly installed on the bottom of the inner wall of the glue container 1. After the first motor 21 runs, it will rotate the glue roller 2 at the bottom. The electric heating element 11 can be an electric heating plate or other object with electric heating effect, which can preheat and heat the glue in the glue container 1, so that the glue in the glue container 1 will not reduce its fluidity due to natural cooling.

[0025] like Figure 1-2As shown, the glue scraping mechanism is installed inside the glue container 1. The glue scraping mechanism includes a second electric push rod 4 fixedly installed on the top of the inner side of the glue container 1, and a scraper 41 fixedly installed on one end of the second electric push rod 4 for scraping off excess glue from the surface of the glue roller 2. The scraper 41 can scrape off excess and thick glue from the surface of the glue roller 2. The scraped glue will fall into the glue container 1 for reuse, thereby reducing glue waste. The extension and retraction of the second electric push rod 4 will drive the scraper 41 to move laterally to adjust the distance between the scraper 41 and the glue roller 2. This allows the amount of glue applied to the paper core to be controlled by adjusting the scraping distance of the scraper 41. For example, if the distance between the scraper 41 and the glue roller 2 is small, there will be less glue on the surface of the glue roller 2, and thus less glue will be applied to the paper core. The same applies to the opposite.

[0026] like Figure 1-2 As shown, a U-shaped rod 42 is fixedly provided on one side of the scraper 41, and the upper glue roller 2 is located inside the U-shaped rod 42. A first cleaning component 43 is fixedly provided on the inner side of the U-shaped rod 42 for cleaning the upper glue roller 2 by pressing against the outer surface of the upper glue roller 2 after the second electric push rod 4 continues to shorten. The U-shaped rod 42 can connect the scraper 41 and the first cleaning component 43. After the second electric push rod 4 continues to shorten, it will push the first cleaning component 43 to the upper glue roller 2 side through the connection of the U-shaped rod 42 until the first cleaning component 43 presses against the upper glue roller 2, and the outer surface of the rotated upper glue roller 2 is cleaned by the first cleaning component 43.

[0027] like Figure 1 and Figure 3 As shown, a fixed frame 31 is fixedly installed on the top of the glue container 1. A first electric push rod 32 is fixedly installed on the top inner side of the fixed frame 31. A connecting frame 33 is fixedly installed at the bottom end of the first electric push rod 32. The pressure roller 3 is rotatably connected in the connecting frame 33. A second motor 34 for driving the pressure roller 3 to rotate is fixedly installed at one end of the connecting frame 33. Both the fixed frame 31 and the connecting frame 33 are U-shaped. The fixed frame 31 can connect the glue container 1 and the first electric push rod 32. The connecting frame 33 can connect the first electric push rod 32 and the pressure roller 3. After the second motor 34 runs, it will drive the pressure roller 3 to rotate. The first motor 21 and the second motor 34 can rotate synchronously in opposite directions through a motion controller or other equipment, which facilitates the conveying of the glued paper core. The synchronous operation of the motor is a public technology and will not be described in detail here.

[0028] Furthermore, the first electric push rod 32 can control the height of the pressure roller 3 after extension and retraction, which facilitates the application of glue to paper cores of different thicknesses by components such as the pressure roller 3 and the gluing roller 2, making it applicable to a wide range of applications.

[0029] like Figure 1 and Figure 3As shown, a vertical rod 5 is fixedly installed on the top inner side of the fixed frame 31, and a horizontal bar 51 is fixedly installed at the bottom of the vertical rod 5. A second cleaning component 52 is fixedly installed at the bottom of the horizontal bar 51 for cleaning the outer surface of the upward-moving pressure roller 3 after the first electric push rod 32 continues to shorten. The vertical rod 5 can connect the horizontal bar 51 and the fixed frame 31, and the horizontal bar 51 can connect the vertical rod 5 and the second cleaning component 52. The first cleaning component 43 and the second cleaning component 52 can be objects with cleaning effect such as cleaning sponges. After the first electric push rod 32 continues to shorten, it will drive the pressure roller 3 to move upward. The second cleaning component 52 can clean the outer surface of the pressure roller 3 after it moves upward and rotates.

[0030] It should be noted that, in use, the gluing device for the honeycomb paperboard manufacturing equipment allows the operator to insert the paper core and other paper body of the honeycomb paperboard between the gluing roller 2 and the pressure roller 3, and drive the gluing roller 2 and the pressure roller 3 to rotate through the first motor 21 and the second motor 34 respectively. After the gluing roller 2 rotates, it will apply the glue box 1 to the bottom of the paper core and other paper body. The pressure roller 3 can press the paper core and other paper body onto the top of the gluing roller 2 during gluing, so that the paper core can fully contact the glue on the surface of the gluing roller 2, which is convenient for gluing.

[0031] The scraper 41 can scrape off excess and thick adhesive from the surface of the glue roller 2. The scraped adhesive will fall into the glue collection box 1 for reuse. The extension and retraction of the second electric push rod 4 will drive the scraper 41 to move laterally to adjust the distance between the scraper 41 and the glue roller 2, so as to control the amount of adhesive applied to the paper core by adjusting the scraping distance of the scraper 41.

[0032] When it is necessary to clean the top roller 2 and the pressure roller 3, the second electric push rod 4 can be controlled to continuously shorten, so as to push the first cleaning component 43 to the side of the top roller 2 through the connection of the U-shaped rod 42 until the first cleaning component 43 abuts against the top roller 2. At this time, the first cleaning component 43 cleans the outer surface of the rotated top roller 2, and the first electric push rod 32 is controlled to continuously shorten to drive the pressure roller 3 to move upward. The second cleaning component 52 can clean the outer surface of the pressure roller 3 after it moves upward and rotates, reducing the cleaning intensity of the top roller 2 and the pressure roller 3 for the workers.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
