Description

Technical Field

[0001] This invention relates to the field of adhesive coating equipment technology, and more specifically to an automated adhesive coating device for honeycomb panel production. Background Technology

[0002] Honeycomb panels are made based on the honeycomb structure principle found in nature. They are constructed by bonding corrugated paper together to form numerous hollow, three-dimensional regular hexagons, creating a core that bears the load. Face paper is then bonded to both sides of this core. This structure endows honeycomb panels with excellent properties such as lightweight, high strength, sound insulation, and heat insulation, making them widely used in packaging, construction, and other fields.

[0003] In the production process of honeycomb panels, when bonding the honeycomb paper core to the face paper, adhesive needs to be applied to the surface of the honeycomb paper core to facilitate subsequent bonding and fixation into a whole with the face paper. Among them, low-viscosity adhesives are widely used in the adhesive coating process of honeycomb paper cores because they have good fluidity and penetrability, which can better wet the surface of the honeycomb paper core and penetrate into its tiny pores, thereby forming a thinner and more uniform coating layer.

[0004] Currently, the coating of honeycomb paper cores mostly adopts the method of rolling adhesive application with an adhesive roller. This method involves evenly distributing adhesive on the surface of the adhesive roller and achieving adhesive application through the rolling contact between the roller and the paper core. However, since the effective bonding area of ​​the honeycomb paper core is only the hexagonal facets on its surface, while the adhesive on the adhesive roller is evenly distributed over the entire surface, when the adhesive roller contacts the paper core, a large amount of adhesive will be applied to the hexagonal pore areas of the paper core. This portion of adhesive cannot be directly utilized during the paper core bonding process, which not only reduces the effective utilization rate of the adhesive but may also lead to insufficient actual adhesive application on the hexagonal facets (effective bonding areas) of the paper core. Summary of the Invention

[0005] This invention provides an automated gluing device for honeycomb panel production to solve the problem that when gluing paper cores, a large amount of adhesive is applied to the hexagonal pore areas of the paper core. This portion of adhesive cannot be directly used during the paper core bonding process, which not only reduces the effective utilization rate of the adhesive but may also lead to insufficient actual adhesive application on the hexagonal facets (effective bonding areas) of the paper core.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] An embodiment of the automated adhesive coating device for honeycomb panel production according to the present invention is as follows: Figures 1 to 9As shown.

[0022] An automated gluing device for honeycomb panel production is disclosed, used to apply glue to the paper core 100 of the honeycomb panel, the paper core 100 having a plurality of regular hexagonal holes. The automated gluing device for honeycomb panel production includes a support 200, a gluing roller 300, a main drive belt 400, a first air blowing component 500, and multiple air cores 600. The gluing roller 300 is rotatably mounted on the support 200, and its surface is coated with adhesive 900. The main drive belt 400 is rotatably mounted on the support 200 and located below the gluing roller 300, defining a conveying space between the main drive belt 400 and the gluing roller 300. The paper core 100 is located within the conveying space and can move horizontally under the traction of the gluing roller 300 and the main drive belt 400; the direction of movement of the paper core 100 is referred to as the first direction. Multiple air cores 600 are evenly distributed around the main drive belt 400 in a circumferential direction, and each air core 600 has a main air hole 610 coaxially formed on it. Each air core 600 is correspondingly positioned within a regular hexagonal hole on the paper core 100, and when the paper core 100 reaches the main drive belt 400, the air core 600 is positioned within the corresponding regular hexagonal hole on the paper core 100. A first air-blowing component 500 is fixedly mounted on the bracket 200. The first air-blowing component 500 supplies air to the main air holes 610 of several air cores 600 located on the upper side of the main drive belt 400 and within a first preset area. The first preset area is the region that the paper core 100 passes through in the first direction from before contacting the coating roller 300 to when the paper core 100 is about to separate from the coating roller 300.

[0023] The air core 600 has a regular hexagonal structure and can match the regular hexagonal holes on the paper core 100. By setting the air core 600 to a regular hexagonal structure, the paper core 100 is assisted in being stretched open, thereby improving the forming quality.

[0024] Furthermore, a transmission roller 700 is rotatably mounted on the support 200, and the transmission roller 700 and the glue-applying roller 300 are driven by friction. A first driving component, which is a motor, is provided on the support 200 to drive the transmission roller 700 to rotate. In use, adhesive 900 is injected between the transmission roller 700 and the glue-applying roller 300, causing the adhesive 900 to adhere to the glue-applying roller 300 as it rotates.

[0025] Furthermore, a feeding belt 210 and a discharging belt 220 are rotatably mounted on the support 200. The feeding belt 210, the main drive belt 400, and the discharging belt 220 are arranged sequentially in the first direction, and in the direction of movement of the paper core 100, the feeding belt 210 is located in front of the discharging belt 220. The paper core 100 can be fed into the main drive belt 400 from the feeding belt 210 side, and then discharged from the main drive belt 400 via the discharging belt 220.

[0026] That is, paper core 100 according to the attached... Figure 3 The direction shown moves from right to left. The direction closer to the arrow is called the front side, and the direction farther from the arrow is called the back side.

[0027] In this embodiment, by setting up a gluing roller 300, a main drive belt 400, a first air blowing component 500, and multiple air cores 600 on the support 200, when applying glue to the upper surface of the paper core 100 of the honeycomb board, adhesive 900 is first applied to the gluing roller 300 to ensure that the amount of adhesive 900 adheres to meet the bonding requirements, while avoiding excessive accumulation of adhesive 900 that could lead to overflow. Then, the gluing roller 300 and the main drive belt 400 are driven to rotate, causing the paper core 100 to move horizontally under the urging of the gluing roller 300 and the main drive belt 400. Before the paper core 100 contacts the glue coating roller 300, and during the process from when the paper core 100 is about to separate from the glue coating roller 300, the air core 600 corresponding to this part of the paper core 100 will enter the first preset area and ventilate in conjunction with the first air blowing element 500. This allows the airflow to be blown out from the main air hole 610 of the air core 600 onto the glue coating roller 300. The blown airflow will cause the adhesive liquid 900 adhering to the glue coating roller 300 to flow from the center area of ​​the regular hexagonal hole of the paper core 100 to the surrounding area. This allows the adhesive liquid 900 to approach the hexagonal facets of the paper core 100, that is, to allow the adhesive liquid 900 to preferentially and fully adhere to the effective bonding area on the paper core 100, thereby improving the utilization rate of the adhesive liquid 900 and increasing the amount of adhesive applied to the hexagonal facets of the paper core 100, thus improving the bonding strength of the paper core 100 when it is bonded to the face paper. As the paper core 100 continues to move along the first direction, the glued paper core 100 detaches from the glued roller 300, and the corresponding air core 600 also moves out of the first preset area of ​​the first air blowing component 500. The first air blowing component 500 stops supplying air to this part of the air core 600. The glued paper core 100 continues to be conveyed to the subsequent process for bonding with the face paper.

[0028] In a further embodiment, the air core 600 is also provided with a plurality of secondary air holes 620, which are evenly distributed on the air core 600 around its axis.

[0029] In a further embodiment, an automated gluing device for honeycomb panel production further includes a second air blowing member 510, which is located behind and connected to the first air blowing member 500 in the direction of movement of the paper core 100. The second air blowing member 510 is used to supply air to the secondary air holes 620 of a plurality of air cores 600 located on the upper side of the main drive belt 400 and within a second preset area. The second preset area is the area that the paper core 100 passes through in the first direction from the beginning of separation from the gluing roller 300 to the complete separation from the gluing roller 300.

[0030] This embodiment incorporates a second air-blowing component 510, see [link / reference] Figure 9 As shown in the figure, the right side of the figure shows the state when the adhesive 900 is located between one edge of the coating roller 300 and the paper core 100. The left side of the figure shows the state when the coating roller 300 is separated from one edge of the paper core 100.

[0031] When the coated paper core 100 detaches from the coating roller 300, the air core 600 corresponding to this part of the paper core 100 will enter the second preset area of ​​the second air blowing component 510 and circulate air in conjunction with the second air blowing component 510. This causes the airflow to be blown out from the secondary air hole 620 of the air core 600 onto the coating roller 300. At the instant the coating roller 300 leaves the upper surface of the paper core 100, the connecting liquid column between the two is broken, and the liquid is made to converge towards the hexagonal facet of the paper core 100, increasing the amount of adhesive 900 at the facet. Furthermore, the airflow blown out from the secondary air hole 620 will also give a reverse thrust to the adhesive 900 located at the hexagonal facet of the paper core 100, preventing the adhesive 900 from flowing downward along the hexagonal facet of the paper core 100.

[0032] In a further embodiment, the main drive belt 400 includes a first belt body 410, a second belt body 420, and a third belt body 430. A first shaft 440 and a second shaft 450 are sequentially rotatably disposed on the bracket 200 along a first direction. The first belt body 410 is sequentially wound around the first shaft 440 and the second shaft 450. The second belt body 420 is sleeved on the first belt body 410 and fixedly connected to it. The third belt body 430 is sleeved on the second belt body 420 and fixedly connected to it. Furthermore, the first belt body 410, the second belt body 420, and the bracket 200 define a plurality of first air chambers 460, and the second belt body 420, the third belt body 430, and the bracket 200 define a plurality of second air chambers 470. The air core 600 is fixedly connected to the third belt 430, and the main air hole 610 of the air core 600 is connected to the first air chamber 460, and the secondary air hole 620 of the air core 600 is connected to the second air chamber 470. The first air blowing element 500 can be connected to the first air chamber 460, and the second air blowing element 510 can be connected to the second air chamber 470.

[0033] The second belt 420 has multiple reinforcing ribs 480 evenly distributed around its circumference. The first air cavity 460 is defined by the first belt 410, the second belt 420, the support 200, and two adjacent reinforcing ribs 480. The second air cavity 470 is defined by the second belt 420, the third belt 430, the support 200, and two adjacent reinforcing ribs 480. The reinforcing ribs 480 support the first belt 410 and the third belt 430 and separate the first air cavity 460 and the second air cavity 470.

[0034] Furthermore, the third belt 430 is provided with supporting ribs along its circumferential direction. By providing supporting ribs, the strength of the third belt 430 is improved, preventing it from deforming during rotation.

[0035] In a further embodiment, the first air blowing component 500 includes an air blowing cylinder 520, which has an air inlet 521 and an air outlet 522. The air inlet 521 is used to connect to an external air pump, and the air outlet 522 is used to communicate with a first air chamber 460 located in a first preset area. The structure of the second air blowing component 510 is the same as that of the first air blowing component 500, and the air inlet 521 of the second air blowing component 510 is used to connect to an external air pump, and the air outlet 522 of the second air blowing component 510 is used to communicate with a second air chamber 470 located in a second preset area.

[0036] Furthermore, the air blower 520 is provided with an abutment plate 523, which is used to contact the reinforcing rib 480. By providing the abutment plate 523, when the abutment plate 523 contacts the reinforcing rib 480, the leakage of air from the air blower 520 can be reduced. However, it should be noted that the abutment plate 523 can only alleviate the leakage, not completely prevent it.

[0037] During use, the two air blowers 520 remain stationary, while the main drive belt 400 moves relative to the two air blowers 520. During the movement of the main drive belt 400, when a portion of the main drive belt 400 reaches the first preset area, the air blower 520 of the first air blower 500 will send air into the first air chamber 460 connected to it. Before the paper core 100 contacts the coating roller 300, and before the paper core 100 is about to separate from the coating roller 300, the gas will be supplied to the main air hole 610 of the corresponding air core 600 and sprayed onto the coating roller 300. The remaining gas can be recovered to the second air chamber 470 through the secondary air hole 620 and discharged after this portion of the main drive belt 400 leaves the first and second preset areas. Similarly, after this part of the main drive belt 400 passes through the first preset area, it will arrive at the second preset area. At this time, the air blower 520 of the second air blowing component 510 will send air to the second air chamber 470 connected to it. During the process of the paper core 100 starting to separate from the glue coating roller 300 to completely separating from the glue coating roller 300, the gas will be supplied to the auxiliary air hole 620 of the corresponding air core 600 and sprayed towards the glue coating roller 300. The remaining gas will be discharged after leaving the first preset area and the second preset area.

[0038] Furthermore, the air pressure supplied by the air pump connected to the air pump 520 of the first air blowing component 500 is greater than the air pressure supplied by the air pump connected to the air pump 520 of the second air blowing component 510. This results in a relatively stronger airflow from the air pump 520 of the first air blowing component 500, improving the flow effect of the airflow in causing the adhesive liquid 900 adhering to the coating roller 300 to flow from the center area of ​​the hexagonal hole of the paper core 100 to the surrounding area. It also makes the airflow from the air pump 520 of the second air blowing component 510 a gentle breeze, only needing to break the connecting liquid column, preventing the airflow from blowing the adhesive liquid 900 outside the edge.

[0039] In a further embodiment, the bracket 200 is also provided with a scraper (the scraper is not shown in the accompanying drawings), and in the rotation direction of the coating roller 300, the scraper is located in front of the transmission roller 700, and a gap is left between the scraper and the coating roller 300.

[0040] That is, the glue-applying roller 300 is in accordance with the attached... Figure 4 The direction shown is clockwise. The direction closer to the arrow is called the front side, and the direction farther from the arrow is called the back side.

[0041] By setting a scraper, after the adhesive 900 is injected between the drive roller 700 and the coating roller 300, when the coating roller 300 rotates and passes the scraper, the adhesive 900 on the coating roller 300 will be pre-scraped by the scraper to control the thickness of the adhesive 900 on the coating roller 300 and prevent the adhesive 900 from dripping.

[0042] In a further embodiment, an automated adhesive coating device for honeycomb panel production further includes a recovery cylinder 800, which is fixedly mounted on a bracket 200 and located behind the drive roller 700 in the rotation direction of the coating roller 300. The recovery cylinder 800 has a first cylinder wall 810 and a second cylinder wall 820, which are sequentially arranged in the rotation direction of the coating roller 300. A gap is left between the first cylinder wall 810 and the coating roller 300 in the rotation direction of the coating roller 300, and the second cylinder wall 820 is located in front of the first cylinder wall 810 and abuts against the coating roller 300.

[0043] Furthermore, a recycling pipe 830 is provided on the recycling cylinder 800, with one end of the recycling pipe 830 connected to the recycling cylinder 800 and the other end connected to an external collection box.

[0044] In this embodiment, by setting up a recycling cylinder 800, when the coating roller 300 rotates to the recycling cylinder 800, the first cylinder wall 810 scrapes off the adhesive 900 on the coating roller 300, causing the adhesive 900 to flow down from the first cylinder wall 810 to the second cylinder wall 820, and finally enter the recycling cylinder 800 for recycling. The adhesive 900 in the recycling cylinder 800 can also be sent to an external collection box through the recycling pipe 830 for further processing and reuse.

[0045] Based on the above embodiments, the specific working process is as follows: When applying adhesive to the upper surface of the paper core 100 of the honeycomb board, adhesive 900 is first applied to the adhesive roller 300 to ensure that the amount of adhesive 900 adheres to meet the bonding requirements, while avoiding excessive accumulation of adhesive 900 that could cause overflow. Then, the adhesive roller 300 and the main drive belt 400 are driven to rotate, causing the paper core 100 to move horizontally under the traction of the adhesive roller 300 and the main drive belt 400.

[0046] The two air blowers 520 remain stationary, while the main drive belt 400 moves relative to the two air blowers 520. During the movement of the main drive belt 400, when a portion of the main drive belt 400 reaches the first preset area, the air blower 520 of the first air blower 500 will deliver air into the first air chamber 460 connected to it. Before the paper core 100 contacts the coating roller 300, and before the paper core 100 is about to separate from the coating roller 300, the gas will supply air to the main air hole 610 of the corresponding air core 600, and the gas will... The airflow sprayed onto the coating roller 300 causes the adhesive 900 adhering to the roller 300 to flow from the center of the hexagonal holes in the paper core 100 outwards. This allows the adhesive 900 to approach the hexagonal facets of the paper core 100, thus preferentially and fully adhering to the effective bonding area of ​​the paper core 100. This improves the utilization rate of the adhesive 900 and increases the amount of adhesive applied to the hexagonal facets of the paper core 100, thereby enhancing the bonding strength of the paper core 100 when bonded to the face paper. The remaining gas can be recovered to the second air chamber 470 through the secondary air hole 620 and discharged after this part of the main drive belt 400 leaves the first and second preset areas.

[0047] After this part of the main drive belt 400 passes through the first preset area, it will arrive at the second preset area. At this time, the air blower 520 of the second air blowing component 510 will send air to the second air chamber 470 connected to it. During the process of the paper core 100 starting to separate from the glue coating roller 300 until it is completely separated from the glue coating roller 300, the gas will be supplied to the auxiliary air hole 620 of the corresponding air core 600 and sprayed towards the glue coating roller 300. The remaining gas will be discharged after leaving the first preset area and the second preset area.

[0048] As the paper core 100 continues to move along the first direction, the glued paper core 100 continues to be conveyed to the subsequent process for bonding with the face paper.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
