Description

Technical Field

[0001] The present invention relates to the technical field of wood-based panel production, and particularly to a glue coating device for the surface of wood-based panels. Background Art

[0002] The production process of artificial wood-based panels mainly includes processes such as flaking, drying, sizing, mat forming, and hot pressing. As an important part of the production, the sizing uniformity directly affects the quality of the final product. In the existing sizing process, manual operation is mainly combined with a glue coating machine for sizing. During the sizing process of the glue coating machine, glue is conveyed to the surface of the coating roller, and through the rotational movement and pressure of the coating roller, the glue is evenly applied to the surface of the panel that needs to be glued.

[0003] Simply using the coating roller is difficult to ensure the uniformity of the glue layer after sizing. Therefore, the existing new glue coating machine uses a leveling roller in cooperation with the coating roller to squeeze the glue between the two, thereby controlling the distribution of the glue on the surface of the coating roller.

[0004] However, this solution will cause the situation of excessive glue dripping in the middle and insufficient glue at the edges, resulting in the affected distribution uniformity of the glue and ultimately affecting the product quality. Moreover, when applying glue by pressing with the coating roller, during double-sided sizing, the upper and lower rollers rotate simultaneously, and pressure needs to be applied to the panel at the same time, resulting in a relatively large applied force. And due to fluctuations in speed control, there may be a speed difference. When facing a relatively thin panel, the panel may be damaged or cracked by pressing, resulting in an increase in the defective rate of the product. At the same time, the existing equipment usually uses conveying rollers or belts for panel conveying. However, the bottom of the panel after double-sided sizing has a coated area, and the conveying by the conveying rollers or belts will cause the uniformity of the glue at the bottom to be damaged, affecting the product quality. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: to provide a glue coating device for the surface of wood-based panels, which solves the problems of insufficient distribution uniformity of glue in the existing panel glue coating machine and a large degree of manual participation.

The first support plate is slidably connected to the main support rod. An adjusting spring is arranged between the first support plate and the main support rod. The clamping mechanism is connected to the main support rod; when the first support plate compresses the adjusting spring, the clamping mechanism approaches the direction of the first support plate, so as to clamp the plate.

[0007] In one embodiment, the spraying box includes a first end wall and a second end wall. A liquid inlet pipe is arranged on the first end wall, and the liquid flow cavity is communicated with the glue storage module through the liquid inlet pipe; in the length direction of the spraying box, the projection area of the second end wall is within the projection area of the first end wall.

[0008] In one embodiment, the area ratio of the projection area of the second end wall to the projection area of the first end wall is 1:2 - 4.

[0009] In one embodiment, the spraying box further includes a first side wall, a second side wall and two third inclined walls arranged between the first end wall and the second end wall. The plane where the first side wall is located is parallel to the plane where the plate is located; the planes where the first side wall and the second side wall are located are perpendicular to each other, and the third inclined walls are respectively connected to the first end wall or the second end wall; the diffusion nozzles are arranged on the first side wall or the second side wall.

[0010] In one embodiment, a return pipe is arranged on the second end wall, and the return pipe is communicated with the glue storage module.

[0011] In one embodiment, at least 3 sections are arranged along the length direction of the spraying box, and each section of the spraying box is detachably and hermetically connected to each other.

[0012] In one embodiment, a control valve is arranged between the diffusion nozzle and the liquid flow cavity.

[0016] The beneficial effects of the present invention are: 1. The wood board surface gluing equipment provided by the present invention uses a spray box with a gradually shrinking liquid flow cavity.

[0018] 3. The gluing module and conveying module used in the wood board surface gluing equipment provided by the present invention receive and support the board after gluing through the second conveying component, so as to avoid partial tilting of the board after gluing, and prevent the gap or angle between the board and the gluing module from changing due to the tilt of the board, thereby ensuring the stability of the gluing environment and further ensuring the uniformity of the glue coating. In addition, the upper surface is sprayed and the lower surface is coated with a rubber roller, so as to avoid cracking and damage caused by excessive force on both sides of the board.

Detailed implementation manners

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Apparently, the described embodiments are some but not all of the embodiments of the present invention; the technical features designed in different implementation manners of the present invention described below can be combined with each other as long as they do not conflict with each other; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0023] In the description of the present invention, it should be noted that all terms used in the present invention (including technical terms and scientific terms) have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present invention belongs, and should not be construed as limiting the present invention; it should be further understood that the terms used in the present invention should be understood as having meanings consistent with their meanings in the context of this specification and the relevant technical field, and should not be understood in an idealized or overly formal sense, unless otherwise defined explicitly in the present invention.

[0024] To describe in detail the technical content, achieved objectives and effects of the present invention, the following is described in conjunction with the embodiments and with reference to the accompanying drawings.

[0025] Please refer to Figures 1 to 7 , a gluing device for the surface of a wood-based panel, which is used for applying glue to both sides of the panel 4, and includes a gluing module 1, a glue storage module 2 and a conveying module 3.

[0026] The gluing module 1 includes an upper gluing component 12 and a lower gluing component 13 arranged between two installation side walls 11. The upper gluing component 12 and the lower gluing component 13 apply glue to both sides of the panel 4 respectively. The glue storage module 2 is arranged above the installation side walls 11, and the glue storage module 2 is connected to the gluing module 1 through pipelines. The conveying module 3 is arranged at the front and rear ends of the gluing module 1 and is used for conveying and receiving the panel 4 to the gluing module 1.

[0027] Specifically, the direction perpendicular to the installation side walls 11 is the width direction of the device, and the direction parallel to the installation side walls 11 is the length direction of the device. The installation side walls 11 enclose to form the housing of the device. Part of the gluing module 1 and the conveying module 3 are arranged inside the housing. The glue storage module 2 is arranged on the top of the installation side walls 11 and can be external or internal, as long as the structure of the device is stable. Those skilled in the art can adjust the structure between the installation side walls 11 according to needs, and no specific limitation is made.

[0028] The upper sizing assembly 12 includes a spraying tank 122 and a sizing roller 121. The spraying tank 122 is arranged between the installation side walls 11. There is a liquid flow chamber 1221 inside the spraying tank 122, and the cross-sectional size of the liquid flow chamber 1221 gradually decreases from one installation side wall 11 to the other installation side wall 11. Diffusion nozzles 1222 are arranged at intervals on the side wall of the spraying tank 122, and the diffusion nozzles 1222 are communicated with the liquid flow chamber 1221. The sizing roller 121 is arranged above the upper surface of the plate 4. Specifically, the spraying tank 122 is a frustum structure as a whole, and has a liquid flow chamber 1221 with a gradually decreasing cross-sectional area of the cavity. Diffusion nozzles 1222 are arranged at intervals at the bottom of the spraying tank 122 or on the side close to the sizing roller 121, and the sizing material in the liquid flow chamber 1221 is evenly sprayed onto the upper surface of the plate 4 through the diffusion nozzles 1222. Compared with setting mechanisms such as pistons in the liquid flow chamber 1221 to supplement pressure, using a uniformly shrinking cavity can maximize the use of space, reduce the proportion of other structures, improve the integration of the equipment, and there is no need to adjust the internal structure of the spraying tank 122 during maintenance, which is convenient for maintenance and repair.

[0029] The sizing roller 121 is arranged behind the spraying tank 122 to evenly apply the sized coating, further ensuring the uniformity of the coating. Specifically, a coating gap can be set between the sizing roller 121 and the upper surface of the plate 4, and those skilled in the art can adjust the size of the coating gap according to the actual coating thickness required. There are lifting adjustment mechanisms such as worms, lifting motors, screws, and lead screws between the sizing roller 121 and the installation side wall 11, enabling the operator to adjust the height of the sizing roller 121, thereby controlling the thickness of the sizing coating. Preferably, the sizing roller 121 can rotate actively by itself, and a cleaning component such as a scraper is provided to clean the surface of the sizing roller 121 to prevent sizing material from adhering.

[0030] The lower sizing assembly 13 includes a sizing roller group 131 and a sizing material supply assembly 132. The sizing material supply assembly 132 supplies sizing material to the sizing roller group 131, and the sizing roller group 131 contacts the lower surface of the plate 4 for coating. Specifically, the sizing roller group 131 can adopt a combination of a lower sizing roller, a lower extrusion roller, and a motor group. The sizing material supply assembly 132 pumps sizing material into the area surrounded by the lower sizing roller and the lower extrusion roller. Or, a scheme where the sizing material supply assembly 132 is a sizing material supply tank can be adopted, and part of the lower sizing roller is located in the sizing material supply tank. The lower sizing roller transfers the sizing material in the sizing material supply tank to the lower surface of the plate 4 by rotation. Preferably, the lower sizing assembly 13 further includes a liquid collection tank 133, which is arranged below the sizing roller group 131 and is used to collect the dripping sizing material. Those skilled in the art can set a suitable lower sizing assembly 13 according to needs, and no specific limitation is made.

[0031] The conveying module 3 includes a first conveying component 31 and a second conveying component 32. The first conveying component 31 is arranged at the front end of the sizing module 1; the second conveying component 32 is arranged at the rear end of the sizing module 1; the second conveying component 32 includes a transmission mechanism 321 and a support member 322. The support member 322 is arranged on the transmission mechanism 321 corresponding to both sides in the width direction of the plate 4, and the support member 322 is slidably connected to the transmission mechanism 321; the support member 322 includes a support main rod 3221, a first support plate 3222 and a clamping mechanism 323. The first support plate 3222 is slidably connected to the support main rod 3221, and an adjustment spring 3223 is arranged between the first support plate 3222 and the support main rod 3221. The clamping mechanism 323 is connected to the support main rod 3221; when the first support plate 3222 compresses the adjustment spring 3223, the clamping mechanism 323 moves closer to the direction of the first support plate 3222, so as to clamp the plate 4. Since the upper sizing component 12 applies sizing in the way of spraying and spreading, the upper sizing component 12 actually applies less force or no force to the plate 4. Therefore, the second conveying component 32 is used to support and clamp the pre-cut edge part of the edge of the plate 3232, so as to receive the plate 4, ensuring that the angle, position and height of the plate 4 do not shift during the sizing process. Specifically, the transmission mechanism 321 can adopt two parallel conveying chains. Those skilled in the art can adjust the specific length and type of the transmission mechanism 321 according to needs. The support member 322 is arranged at both ends of the first bracket distributed along the width direction of the equipment and is arranged on the conveying chain. The whole support member 322 can slide on the first bracket, so that the support member 322 can be adjusted according to the width of the plate 4. An adjustment spring 3223 is arranged between the first support plate 3222 and the support main rod 3221, and the adjustment spring 3223 makes the first support plate 3222 move in the direction away from the support main rod 3221. The clamping mechanism 323 can adopt design forms such as a clamping plate 3232 cooperating with a flipping cylinder, a telescopic rod, a hinge connecting rod structure, etc., so that the clamping mechanism 323 is far away from the first support plate 3222 when the first support plate 3222 does not contact the plate 4, and moves closer to the first support plate 3222 during support, ensuring that the clamping mechanism 323 does not interfere with the contact between the plate 4 and the first support plate 3222. The support member 322 moves with the conveying chain and rotates at one end close to the sizing module 1. During the rotation process, the first support plate 3222 gradually contacts the plate 4 from bottom to top. During the process, the first support plate 3222 is pressed and slides relative to the support main rod 3221, and the pressure is transmitted to the adjustment spring 3223, triggering the clamping mechanism 323 to close. After being pressed and stabilized, the height of the upper surface of the first support plate is flush with the highest point of the sizing roller set 131, ensuring that the plate 4 does not tilt during the conveying process. Specifically, those skilled in the art can adjust the interval between the second conveying component 32 and the sizing module 1 according to the specifications of the plate 4, so that the second conveying component 32 can receive the plate 4. Specifically, multiple groups of support members 322 are arranged at intervals, so that the plate 4 is supported by at least 4 groups of support members 322 after sizing.

[0032] It is understandable that the glue module 1 and the conveying module 3 used in the wood board surface glue coating equipment provided by the present invention receive and support the glued board 4 through the second conveying assembly 32, so as to avoid partial tilting of the board 4 after glue coating, and prevent the gap or angle between the board 4 and the glue module 1 from changing due to the tilt of the board 4, thereby ensuring the stability of the glue coating environment and further ensuring the uniformity of the glue coating. In addition, the upper surface is sprayed and the lower surface is coated with a rubber roller, so as to avoid excessive force on both sides of the board 4, resulting in cracking and damage.

[0033] Preferably, a support protrusion is provided on the surface of the first support plate 3222, and the support protrusion can further reduce the contact area with the plate 4, thereby reducing the area that needs to be trimmed later.

[0034] Preferably, a guiding mechanism is provided on the first conveying assembly 31 , and the guiding mechanism enables the plate 4 to be conveyed to the gluing module 1 at a set position.

[0035] In one embodiment, the spray box 122 includes a first end wall 1223 and a second end wall 1224. The first end wall 1223 is provided with a liquid inlet pipe 21, and the liquid flow cavity 1221 is connected to the glue storage module 2 through the liquid inlet pipe 21; in the length direction of the spray box 122, the projection area of ​​the second end wall 1224 is within the projection area of ​​the first end wall 1223. The length direction of the spray box 122 is the width direction of the device. The spray box 122 is fed with liquid from the end face of the larger side of the prism structure, so that the glue flows along the direction in which the liquid flow cavity 1221 gradually shrinks. After the glue is sprayed out, the gradually shrinking cavity supplements the pressure, so that the glue pressure at different positions in the liquid flow cavity 1221 remains consistent, thereby ensuring the uniformity of the sprayed glue.

[0036] In one embodiment, the area ratio of the projection area of ​​the second end wall 1224 to the projection area of ​​the first end wall 1223 is 1:2 to 4. This arrangement ensures that the liquid flow cavity 1221 can supplement the pressure while the end cavity is not too small to cause excessive pressure, further ensuring pressure uniformity.

[0037] In one embodiment, the spraying box 122 further includes a first side wall 1225, a second side wall 1226, and two third inclined walls 1227 disposed between the first end wall 1223 and the second end wall 1224. The plane where the first side wall 1225 is located is parallel to the plane where the plate 4 is located; the planes where the first side wall 1225 and the second side wall 1226 are located are perpendicular to each other, and the third inclined walls 1227 are respectively connected to the first end wall 1223 or the second end wall 1224; the diffusion nozzle 1222 is disposed on the first side wall 1225 or the second side wall 1226. That is, the first side wall 1225 and the second side wall 1226 are respectively parallel to the horizontal plane or the vertical plane. In the width direction of the device, the projection area of the second end wall 1224 is located at the lower left corner of the projection area of the first end wall 1223. With such a setting, it is ensured that the positions and heights of the diffusion openings can be unified, further ensuring that the ejected adhesive can adhere to the surface of the plate 4 at the same time, avoiding the lateral flow of the adhesive, and ensuring the uniformity of the adhesive distribution.

[0038] In one embodiment, a return pipe 22 is provided on the second end wall 1224, and the return pipe 22 is communicated with the glue storage module 2. After the return pipe 22 is provided, the operator can adjust the pressure in the spraying box 122 by adjusting the flow rates of the glue in the liquid inlet pipe 21 and the return pipe 22, so as to accurately control the ejection amount of the glue, enhancing the operability of the device. At the same time, it can avoid excessive pressure at the end, resulting in excessive ejection of the glue near the second end wall 1224, and further ensuring the uniformity of the pressure in the liquid flow chamber 1221.

[0039] In one embodiment, at least 3 sections of the spraying box 122 are arranged along the length direction, and each section of the spraying box 122 is detachably and hermetically connected to each other. Specifically, the spraying box 122 is arranged in a multi-section sealed connection, enabling the operator to separately replace and maintain different areas of the spraying box 122, effectively reducing the maintenance difficulty and cost.

[0040] In one embodiment, a control valve is provided between the diffusion nozzle 1222 and the liquid flow chamber 1221. The setting of the control valve enables the operator to open or close the diffusion nozzles 1222 at different positions, enabling the operator to adjust the glue spraying area, enhancing the operability, and enabling the wood board surface gluing device to adapt to plates 4 of different specifications.

[0041] In one embodiment, a limiting block is provided on the supporting main rod 3221. When the limiting block restricts the first support plate 3222 from contacting the plate 4, the upper surface of the first support plate 3222 is not lower than the highest point of the glue application roller set 131. Specifically, the limiting block can adopt an adjusting bolt, and the lowest point of the upper surface of the first support plate 3222 is adjusted by tightening or loosening the adjusting bolt to ensure the supporting height of the first support plate 3222 for the plate 4, avoiding warping of the unglued part of the plate 4 caused by the too low first support plate 3222.

[0042] In one embodiment, the conveying module 3 further includes a detection component 33. The detection component 33 is disposed on the first conveying component 31 and is electrically connected to the glue storage module 2. After the detection component 33 detects that the board 4 enters the set area, it controls the glue storage module 2 to provide glue. The detection component 33 can be a photoelectric sensor or an infrared sensor. The detection component 33 is disposed at one end of the first conveying component 31 close to the spraying box 122. When the detection component 33 detects that the board 4 moves to the specified area, the glue storage module 2 and the glue application module 1 work to apply glue. When the detection component 33 detects that the board 4 moves out of the specified area, the glue storage module 2 stops. Specifically, those skilled in the art can select a suitable detection component 33 according to needs, and no specific limitation is made.

[0043] Preferably, the conveying module 3 further includes a purging component 34. The purging component 34 is disposed on the first conveying component 31 to purge the upper and lower surfaces of the board 4.

[0044] In one embodiment, the clamping mechanism 323 includes an L-shaped connecting plate 3231, a clamping plate 3232, a first connecting plate 3233, and a first connecting rod 3234. One end of the horizontally extending portion of the L-shaped connecting plate 3231 is connected to the outer side of the support main rod 3221, and one end of the vertically extending portion of the L-shaped connecting plate 3231 is hinged with the clamping plate 3232. A first sliding groove 3235 distributed in the vertical direction is provided in the L-shaped connecting plate 3231. One end of the first connecting plate 3233 is disposed between the first support plate 3222 and the adjusting spring 3223, and the other end of the first connecting plate 3233 is slidably connected to the first sliding groove 3235. A second sliding groove 3236 is provided on the first connecting plate 3233 in the width direction of the equipment. One end of the first connecting rod 3234 is hinged with the clamping plate 3232, and the other end of the first connecting rod 3234 is slidably connected to the second sliding groove 3236. After the first support plate 3222 is pressed, it drives the entire first connecting plate 3233 to move downward. The first connecting rod 3234 is stressed to pull the clamping plate 3232 to rotate, so that the clamping plate 3232 completes the clamping action. With such a setting, the overall structure is simple and reliable. The clamping plate 3232 is triggered by the gravity of the board 4 to clamp, so that the clamping plate 3232 can gradually clamp the board 4 during the process of gradually supporting the board 4 as it rotates with the first support plate 3222, avoiding interference of the clamping plate 3232 with the work of the first support plate 3222.

[0052] The working principle of this embodiment is as follows: The sheet 4 is conveyed to the first conveying component 31 by an external device or an operator, and the first conveying component 31 conveys the sheet 4 to the gluing module 1. During the conveying process, after the detection component 33 detects that the sheet 4 enters the set area, it controls the glue storage module 2 and the gluing module 1 to start. The lower gluing component 13 applies glue to the lower surface of the sheet 4 through the glue application roller set 131 and makes the sheet 4 continue to move forward. At the same time, the spraying box 122 of the upper gluing component 12 sprays glue on the upper surface of the sheet 4, and the glue is spread evenly by the glue spreading roller 121. The glued sheet 4 contacts the support member 322 that gradually rotates to the upper side, and the first support plate 3222 in the support member 322 contacts and gradually supports the sheet 4. During the supporting process, the first support plate 3222 is pressed and slides relative to the support main rod 3221, and transmits the pressure to the adjusting spring 3223, triggering the clamping mechanism 323 to close. After being pressed and stabilized, the height of the upper surface of the first support plate is flush with the highest point of the glue application roller set 131, and the support member 322 completes clamping and continues to move. When the detection component 33 detects that the sheet 4 has moved out of the specified area after a set time, the gluing of the upper and lower surfaces of the sheet 4 is completed, and the detection component 33 controls the glue storage module 2 to stop. At this time, the sheet 4 is completely supported by the second conveying component 32 and conveyed to the set position, waiting for an external device or person to receive it.
