Description

Technical Field

[0001] The invention relates to the technical field of gluing wood panels, in particular to a gluing device and a gluing method for wood panel processing. Background Art

[0002] The main purpose of gluing boards is to firmly bond two or more boards together. When making plywood, by applying glue between the veneers, they can be tightly bonded after processes such as hot pressing to form plywood with a certain thickness and strength. This bonding can improve the overall performance of the board, allowing it to withstand a certain amount of external force without separation. Gluing can also enhance the stability of the board. In the production of solid wood composite flooring, by combining different wood layers together through gluing, it can reduce the deformation of the wood caused by factors such as humidity changes, making the floor more flat and stable during use.

[0003] However, due to the characteristics of the board itself, if the surface of the wood board is uneven, with depressions, protrusions or burrs, the glue will accumulate in the depressions and less in the protrusions. The rough surface of the wood board will cause the glue to adhere more to the high points, while the low points may not be fully exposed to the glue.

[0033] The present application is further described in detail below through drawings and examples.

[0035] The glue coating assembly 4 includes a frame 41, and a fixed roller 42 and a glue coating roller 49 are rotatably connected between the frames 41. The fixed roller 42 is located below the glue coating roller 49, and the top of the fixed roller 42 is flush with the top of the conveyor belt 1. A chute 46 is provided on the inner side of the frame 41, and a slider 47 is slidably connected inside the chute 46. An auxiliary roller 43 is rotatably connected between the two sliders 47, and the auxiliary roller 43 is located on the left side of the glue coating roller 49. A glue box 44 is fixedly installed between the tops of the frames 41, and a glue discharge nozzle 45 is fixedly installed at the bottom of the glue box 44. The glue discharge nozzle 45 is located above the auxiliary roller 43 and the glue coating roller 49, and the glue discharge nozzle 45 is electrically connected to the controller 5. An electric push rod 48 is fixedly installed inside the chute 46, and the output end of the electric push rod 48 is fixedly installed on the side of the slider 47. The electric push rod 48 is electrically connected to the controller 5. A power motor is provided inside the slider 47, and the output shaft of the power motor is fixedly connected to the auxiliary roller 43.

[0036] In this embodiment, when the wood board is coated with glue, the glue inside the glue box 44 flows through the glue discharge nozzle 45 to between the glue coating roller 49 and the auxiliary roller 43 below. The glue can be coated on the outside of the glue coating roller 49 by relative rotation of the two, and the slider 47 can be moved along the slide groove 46 by starting the electric push rod 48, so as to adjust the position of the auxiliary roller 43. The thickness of the glue on the surface of the glue coating roller 49 can be changed by adjusting the position between the auxiliary roller 43 and the glue coating roller 49, so as to adjust the thickness of the glue coating on the wood board. When coating the glue, the wood board passes between the glue coating roller 49 and the fixed roller 42, and the glue is coated on the outside of the wood board by the rolling and squeezing of the glue coating roller 49. The glued wood board is collected by an external collecting device.

[0037] Reference Figures 1 to 7 In one aspect of this embodiment, a loading port 26 is fixedly installed on the top of the containing box 25, a power motor 210 is fixedly installed on the front of the containing box 25, and the output end of the power motor 210 movably penetrates the side wall of the containing box 25 and is fixedly connected to the side of the rotating rod 216. The front and rear inner walls of the containing box 25 are both threadedly penetrated by a screw rod 211, the inner end of the screw rod 211 is rotatably connected to an adjustment plate 212, the outer end of the screw rod 211 is fixedly installed with a knob 213, the outer wall of the adjustment plate 212 is attached to the inner wall of the containing box 25, and a convex block is fixedly installed on the bottom of the adjustment plate 212, and the bottom of the convex block is attached to the top of the adjustment scraper 217. First side panels 21 are fixedly installed on both the front and rear sides of the conveyor belt 1, a cleaning blade 22 is fixedly installed between the two first side panels 21, the cleaning blade 22 is located above the conveyor belt 1 and on the left side of the containing box 25, a dust hopper 23 is fixedly installed between the tops of the first side panels 21 and above the cleaning blade 22, a dust pipe 24 is fixedly installed on the top of the dust hopper 23, and the dust pipe 24 is connected to the inside of the dust hopper 23.

[0038] In this embodiment, when gluing the wood board, the wood board is transported by the conveyor belt 1. When the wood board passes through the cleaning blade 22, the cleaning blade 22 can scrape off the burrs and protrusions on the surface of the wood board. When scraping, the dust suction fan connected to the dust suction pipe 24 can clean the burrs and impurities of the board itself through the dust suction hopper 23. After cleaning, the board moves to the bottom of the containing box 25, and the rotating rod 216 is driven to rotate by starting the power motor 210. The rotating rod 216 can drive the adjusting scraper 217 to rotate. After the adjusting scraper 217 rotates, the bottom glue inside the containing box 25 will drip onto the wood board below. After dripping, the bottom glue on the surface of the wood board is flattened by the adjusting scraper 217 when the wood board moves. When flattening, the side grooves on the surface of the wood board can be flattened by the bottom glue. After flattening, the wood board is heated and dried by the heating mechanism 3, thereby realizing the pretreatment of the wood board and ensuring that the wood board can be evenly coated with glue when gluing.

[0039] After the base glue is applied, the bottom groove 214 can be resealed by swinging the adjustment scraper 217. Before and after sealing, the gravity is detected by the gravity sensor 29 below, so that the amount of base glue applied on the wood board can be known, and the power of the heating mechanism 3 can be controlled by the controller 5. When more base glue is used, the power of the heating mechanism 3 is increased to ensure that more base glue and more base glue inside the holes can be solidified, further ensuring the uniformity of the next step of gluing, and the screw rod 211 is driven to rotate by turning the knob 213, and the adjustment plate 212 can be driven to move by the rotation of the screw 211. The base glue is placed between the two adjustment plates 212. By changing the position of the adjustment plate 212, it is ensured that when the wood boards of different widths are coated with base glue, the base glue will not flow on the outside;

[0040] And when the heating power becomes larger, the degree of curing of the base glue on the surface of the wood board is higher. The higher degree of curing means that the overall flatness of the base glue is slightly lower, so that thicker glue is needed to ensure the uniformity of the glue when applying the glue. At this time, the movement of the electric push rod 48 and the glue discharge speed of the glue discharge nozzle 45 are adjusted according to the change of the gravity sensor 29, so that the thickness of the glue on the surface of the glue roller 49 can be adjusted, thereby realizing the adjustment of the glue coating thickness, ensuring that the glue can be evenly applied under different heating powers.

[0041] This embodiment also discloses a gluing method of the gluing device for wood board processing, comprising the following steps:

[0042] Step 1: The wood board is transported by the conveyor belt 1, and the burrs on the surface of the wood board are scraped off by the cleaning blade 22, and the dust is sucked into the dust suction fan through the dust suction hopper 23 connected to the dust suction pipe 24, so as to clean the surface of the wood board;

[0043] Step 2: Open the adjustable scraper 217 to spread the glue inside the container 25 on the wood board, and adjust the scraper 217 to scrape the base glue flat, pre-apply the base glue and scrape it, so that the uneven pits on the surface of the wood board can be pre-filled to ensure the uniformity of subsequent glue coating;

[0044] Step 3: The gravity sensor 29 is used to detect the front and back change of the base glue. When the base glue is used more, the controller 5 controls the heating mechanism 3 to increase the drying power of the heating mechanism 3 to ensure that the base glue filling the groove can solidify.

[0045] Step 4: When the drying power is increased, the surface of the base glue is relatively dry after drying. At this time, the electric push rod 48 is started by the controller 5 to drive the slider 47 and the auxiliary roller 43 to move, and the distance between the auxiliary roller 43 and the glue roller 49 is changed, and the glue output of the glue nozzle 45 is changed. By outputting more glue, the surface of the wood board is evenly coated with glue.

[0046] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0047] Working principle: When the wood board is coated with glue, the glue inside the glue box 44 flows to the glue roller 49 and the auxiliary roller 43 below through the glue nozzle 45. The glue can be coated on the outside of the glue roller 49 by the relative rotation of the two, and the slider 47 can be moved along the slide 46 by starting the electric push rod 48, so as to adjust the position of the auxiliary roller 43. The thickness of the glue on the surface of the glue roller 49 can be changed by adjusting the position between the auxiliary roller 43 and the glue roller 49, so as to adjust the thickness of the glue coated on the wood board. When coating the glue, the wood board passes between the glue roller 49 and the fixed roller 42, and the glue is coated on the outside of the wood board by the rolling and squeezing of the glue roller 49. The glued wood board is collected by an external collecting device; when coating the wood board with glue, the wood board is transported by the conveyor belt 1, and when the wood board is transported, when the wood board passes through the cleaning blade When the wood board is moved to the bottom of the storage box 25, the power motor 210 is started to drive the rotating rod 216 to rotate, and the rotating rod 216 can drive the adjusting scraper 217 to rotate. After the adjusting scraper 217 rotates, the base glue inside the storage box 25 will drip onto the wood board below. After dripping, the base glue on the surface of the wood board is flattened by the adjusting scraper 217 when the wood board moves. When flattening, the side grooves on the surface of the wood board can be flattened by the base glue. After flattening, the wood board is heated and dried by the heating mechanism 3, thereby realizing the pretreatment of the wood board and ensuring that the wood board can be evenly coated with glue when coating.

[0048] After the base glue is applied, the bottom groove 214 can be resealed by swinging the adjustment scraper 217. Before and after sealing, the gravity is detected by the gravity sensor 29 below, so that the amount of base glue applied on the wood board can be known, and the power of the heating mechanism 3 can be controlled by the controller 5. When more base glue is used, the power of the heating mechanism 3 is increased to ensure that more base glue and more base glue inside the holes can be solidified, further ensuring the uniformity of the next step of gluing, and the screw rod 211 is driven to rotate by turning the knob 213, and the adjustment plate 212 can be driven to move by the rotation of the screw 211. The base glue is placed between the two adjustment plates 212. By changing the position of the adjustment plate 212, it is ensured that when the wood boards of different widths are coated with base glue, the base glue will not flow on the outside;

[0049] And when the heating power becomes larger, the degree of curing of the base glue on the surface of the wood board is higher. The higher degree of curing means that the overall flatness of the base glue is slightly lower, so that thicker glue is needed to ensure the uniformity of the glue when applying the glue. At this time, the movement of the electric push rod 48 and the glue discharge speed of the glue discharge nozzle 45 are adjusted according to the change of the gravity sensor 29, so that the thickness of the glue on the surface of the glue roller 49 can be adjusted, thereby realizing the adjustment of the glue coating thickness, ensuring that the glue can be evenly applied under different heating powers.

At this time, the controller (5) starts the electric push rod (48) to drive the slider (47) and the auxiliary roller (43) to move, and by changing the distance between the auxiliary roller (43) and the glue coating roller (49), and by changing the glue output of the glue nozzle (45), a larger glue output is achieved to ensure that the surface of the wood board is evenly coated with glue.
