Description

Technical Field

[0001] The invention relates to the technical field of wooden board production, in particular to a wooden board surface gluing device. Background Art

[0002] The production process for artificial wood panels primarily involves flaking, drying, gluing, laying, and hot pressing. Gluing, a crucial step in production, directly impacts the quality of the final product, ensuring uniformity. Currently, the gluing process primarily relies on manual application combined with a gluing machine. During this process, the gluing machine delivers glue to the surface of a gluing roller, which, through its rotation and pressure, evenly applies the glue to the surface of the panel.

[0003] It is difficult to ensure the uniformity of the glue layer after gluing by simply using a glue coating roller. Therefore, the existing new glue coating machine uses a glue leveling roller and a glue coating roller to squeeze the glue between the two, thereby controlling the distribution of glue on the surface of the glue coating roller.

[0004] However, this solution will cause excessive glue dripping in the middle and insufficient glue at the edges, which will affect the uniformity of glue distribution and ultimately affect product quality. In addition, the glue roller applies pressure to the glue. When applying glue on both sides, the upper and lower rollers rotate simultaneously, and pressure needs to be applied to the sheet at the same time, resulting in a large force. In addition, due to fluctuations in speed control, speed differences may occur. When facing thinner sheets, the sheet may be crushed or cracked, resulting in an increase in product defect rates. At the same time, existing equipment usually uses conveyor rollers or belts to convey sheets, but the bottom of the sheet after double-sided glue coating has a glue coating area. Conveying with conveyor rollers or belts will cause the uniformity of the glue at the bottom to be destroyed, affecting product quality. Summary of the Invention

[0014] In one embodiment, the spray box also 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 nozzle is arranged on the first side wall or the second side wall.

[0015] In one embodiment, a return pipe is provided on the second end wall, and the return pipe is communicated with the glue storage module.

[0022] The beneficial effects of the present invention are:

[0023] 1. The wood board surface gluing equipment provided by the present invention uses a spray box with a gradually shrinking liquid flow cavity.

[0025] 3. The wood board surface gluing equipment provided by the present invention utilizes a gluing module and a conveying module. The second conveying assembly receives and supports the glued board, preventing partial tilting of the board after gluing. This prevents any changes in the gap or angle between the board and the gluing module caused by tilting, thereby ensuring a stable gluing environment and, in turn, a uniform coating of the glue. Furthermore, the system utilizes spray coating on the upper surface and a rubber roller coating on the lower surface, preventing excessive stress on both sides of the board, which could cause cracking or damage.

DETAILED DESCRIPTION

[0036] In order to make the purpose, 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. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments; the technical features designed in different implementation modes 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] 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 generally understood by ordinary technicians in the field to which the present invention belongs, and should not be understood as limiting the present invention; it should be further understood that the terms used in the present invention should be understood to have the same meanings as these terms in the context of this specification and the relevant field, and should not be understood in an idealized or overly formal sense, unless explicitly defined as such in the present invention.

[0038] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0039] Please refer to Figures 1 to 7 A wood board surface gluing device is used for double-sided gluing of a board 4, including a gluing module 1, a glue storage module 2 and a conveying module 3.

[0040] The gluing module 1 includes an upper gluing assembly 12 and a lower gluing assembly 13, positioned between two mounting sidewalls 11. These assemblies apply glue to both sides of the sheet material 4. A glue storage module 2 is positioned above the mounting sidewalls 11 and is connected to the gluing module 1 via a pipeline. A delivery module 3, located at the front and rear ends of the gluing module 1, delivers and receives the sheet material 4 to and from the gluing module 1.

[0041] Specifically, the direction perpendicular to the mounting sidewalls 11 is the width direction of the device, and the direction parallel to the mounting sidewalls 11 is the length direction of the device. The mounting sidewalls 11 enclose and form the housing of the device. The glue application module 1 and the conveying module 3 are partially disposed within the housing. The glue storage module 2 is disposed on top of the mounting sidewalls 11 and can be external or internal to ensure the stability of the device structure. Persons skilled in the art can adjust the structure between the mounting sidewalls 11 as needed, and this is not specifically limited.

[0042] The upper gluing assembly 12 includes a spray box 122 and a glue-distributing roller 121. The spray box 122 is positioned between the mounting side walls 11 and contains a liquid flow chamber 1221, the cross-sectional size of which gradually decreases from one mounting side wall 11 to the other. Diffusion nozzles 1222 are spaced apart along the side walls of the spray box 122, communicating with the liquid flow chamber 1221. The glue-distributing roller 121 is positioned above the upper surface of the sheet 4. Specifically, the spray box 122 has a prism-shaped structure and contains a liquid flow chamber 1221 with a gradually decreasing cross-sectional area. Diffusion nozzles 1222 are spaced apart at the bottom of the spray box 122 or on one side near the glue-distributing roller 121. The glue in the liquid flow chamber 1221 is evenly sprayed onto the upper surface of the sheet 4 by the diffusion nozzles 1222. Compared with setting up a piston or other pressure-supplementing mechanism in the liquid flow chamber 1221, the use of a uniformly reduced 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 spray box 122 during maintenance, which facilitates maintenance and inspection.

[0043] The glue roller 121 is arranged behind the spray box 122 to evenly apply the sprayed rubber coating to further ensure the uniformity of the coating. Specifically, a coating gap can be set between the glue roller 121 and the upper surface of the plate 4. The size of the coating gap can be adjusted by those skilled in the art according to the actual coating thickness as needed. A lifting and adjusting mechanism such as a worm, a lifting motor, a screw, and a lead screw is provided between the glue roller 121 and the mounting side wall 11, so that the operator can adjust the height of the glue roller 121, thereby controlling the thickness of the rubber coating. Preferably, the glue roller 121 can be rotated by itself actively, and a cleaning component such as a scraper is provided to clean the surface of the glue roller 121 to prevent the rubber from adhering.

[0044] The lower gluing assembly 13 includes a gluing roller assembly 131 and a gluing supply assembly 132. The gluing supply assembly 132 supplies glue to the gluing roller assembly 131, which then contacts the lower surface of the sheet 4 to apply glue. Specifically, the gluing roller assembly 131 may comprise a combination of a lower gluing roller, a lower squeeze roller, and a motor assembly. The gluing supply assembly 132 pumps glue into the area enclosed by the lower gluing roller and the lower squeeze roller. Alternatively, the gluing supply assembly 132 may be configured as a glue supply trough, with the lower gluing roller partially positioned within the trough. The lower gluing roller rotates to transfer the glue within the trough to the lower surface of the sheet 4. Preferably, the lower gluing assembly 13 also includes a liquid collection trough 133, disposed below the gluing roller assembly 131, for collecting dripping glue. Those skilled in the art may configure an appropriate lower gluing assembly 13 as needed, without specific limitation.

[0045] The conveying module 3 includes a first conveying assembly 31 and a second conveying assembly 32. The first conveying assembly 31 is arranged at the front end of the gluing module 1; the second conveying assembly 32 is arranged at the rear end of the gluing module 1; the second conveying assembly 32 includes a transmission mechanism 321 and a support member 322. The support member 322 is arranged on the transmission mechanism 321 on both sides corresponding to 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 supporting main rod 3221, a first supporting plate 3222 and a clamping mechanism 323. The first supporting plate 3222 is slidably connected to the supporting main rod 3221. An adjustment spring 3223 is provided between the first supporting plate 3222 and the supporting main rod 3221, and the clamping mechanism 323 is connected to the supporting main rod 3221; when the first support plate 3222 compresses the adjustment spring 3223, the clamping mechanism 323 approaches the direction of the first support plate 3222, thereby clamping the plate 4. Since the upper gluing assembly 12 applies glue by spraying and spreading evenly, the upper gluing assembly 12 actually applies little or no force to the plate 4. Therefore, the second conveying assembly 32 is used to support and clamp the pre-cut edge portion of the plate 3232 material to receive the plate 4, ensuring that the angle, position and height of the plate 4 do not shift during the gluing process. Specifically, the transmission mechanism 321 can use two parallel conveying chains. Those skilled in the art can adjust the specific length and type of the transmission mechanism 321 as needed. The support members 322 are arranged at both ends of the first bracket distributed along the width of the equipment and are arranged on the conveying chain. The support members 322 can slide on the first bracket as a whole, so that the support members 322 can be adjusted according to the width of the plate 4. An adjustment spring 3223 is provided between the first support plate 3222 and the support main rod 3221. The adjustment spring 3223 causes the first support plate 3222 to move away from the support main rod 3221. The clamping mechanism 323 can be designed in the form of a clamping plate 3232 in conjunction with a tilting cylinder, a telescopic rod, a hinge connecting rod structure, etc., so that the clamping mechanism 323 is away from the first support plate 3222 when the first support plate 3222 is not in contact with the plate 4, and approaches the first support plate 3222 when supporting the plate 4, 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 the end close to the gluing module 1. During the rotation, 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 with 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 gluing roller group 131, ensuring that the plate 4 does not tilt during the conveying process. Specifically, those skilled in the art can adjust the spacing between the second conveying assembly 32 and the gluing module 1 according to the specifications of the plate 4 so that the second conveying assembly 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 four groups of support members 322 after gluing.

[0046] It is understood that the wood board surface gluing equipment provided by the present invention employs a gluing module 1 and a conveying module 3, which receive and support the glued board 4 via a second conveying assembly 32. This prevents the board 4 from partially tilting after gluing, and prevents any change in the gap or angle between the board 4 and the gluing module 1 caused by tilting. This ensures a stable gluing environment and, in turn, a uniform coating of the glue. Furthermore, the overall system employs spray coating on the upper surface and a rubber roller coating on the lower surface, preventing excessive stress on both sides of the board 4, which could cause cracking or damage.

[0047] Preferably, the surface of the first support plate 3222 is provided with a support protrusion, which can further reduce the contact area with the plate 4 and reduce the area that needs to be trimmed later.

[0048] Preferably, a guide mechanism is provided on the first conveying assembly 31 , and the guide mechanism enables the plate 4 to be conveyed to the gluing module 1 at a set position.

[0049] 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, through which the liquid flow chamber 1221 communicates with the glue storage module 2. Along the length of the spray box 122, the projection of the second end wall 1224 is within the projection of the first end wall 1223. The length of the spray box 122 is the width of the device. Liquid enters the spray box 122 from the end face on the larger side of the prism structure. This allows the glue to flow along the gradually shrinking direction of the liquid flow chamber 1221. After the glue is sprayed, the gradually shrinking cavity replenishes the pressure, maintaining consistent glue pressure at different locations within the liquid flow chamber 1221, thereby ensuring uniform glue spraying.

[0050] In one embodiment, the area ratio of the projected area of ​​the second end wall 1224 to the projected area of ​​the first end wall 1223 is 1:2 to 4. This arrangement ensures that the liquid flow cavity 1221 can replenish the pressure while the end cavity is not too small to cause excessive pressure, further ensuring pressure uniformity.

[0051] In one embodiment, the spray 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 of the first side wall 1225 is parallel to the plane of the sheet 4; the planes of the first side wall 1225 and the second side wall 1226 are perpendicular to each other. The third inclined walls 1227 are connected to the first end wall 1223 or the second end wall 1224, respectively. The diffusion nozzle 1222 is disposed on the first side wall 1225 or the second side wall 1226. Specifically, the first side wall 1225 and the second side wall 1226 are parallel to the horizontal or vertical plane, respectively. Across the width of the apparatus, the projection of the second end wall 1224 is located at the lower left corner of the projection of the first end wall 1223. This arrangement ensures uniform position and height of the diffusion nozzle, further ensuring that the sprayed adhesive adheres to the surface of the sheet 4 simultaneously, preventing lateral flow of the adhesive and ensuring uniform distribution of the adhesive.

[0052] In one embodiment, a return pipe 22 is provided on the second end wall 1224 and communicates with the adhesive storage module 2. The provision of the return pipe 22 allows the operator to adjust the pressure within the spray chamber 122 by adjusting the flow of adhesive in the liquid inlet pipe 21 and the return pipe 22, thereby precisely controlling the amount of adhesive sprayed, enhancing the operability of the equipment. This also prevents excessive pressure at the end, which could result in excessive adhesive spraying near the second end wall 1224, further ensuring uniform pressure within the liquid flow chamber 1221.

[0053] In one embodiment, the spray box 122 is provided in at least three sections along its length, and each section of the spray box 122 is detachably and sealedly connected to each other. Specifically, the spray box 122 is provided with multiple sections of sealed connections, allowing operators to replace and maintain different areas of the spray box 122 separately, which can effectively reduce maintenance difficulty and cost.

[0054] In one embodiment, a control valve is provided between the diffusion nozzle 1222 and the liquid flow chamber 1221. The provision of the control valve allows the operator to open or close the diffusion nozzle 1222 at different positions, allowing the operator to adjust the glue spraying area, enhancing operability, and allowing the wood board surface glue coating device to adapt to boards 4 of different specifications.

[0055] In one embodiment, a stopper is provided on the main support rod 3221. The stopper limits the upper surface of the first support plate 3222 to no lower than the highest point of the glue roller assembly 131 when the first support plate 3222 contacts the sheet 4. Specifically, the stopper can be an adjustment bolt. By tightening or loosening the adjustment bolt, the lowest point of the upper surface of the first support plate 3222 can be adjusted to ensure the support height of the sheet 4 by the first support plate 3222, thereby preventing the un-glued portion of the sheet 4 from warping due to the first support plate 3222 being too low.

[0056] In one embodiment, the conveying module 3 further includes a detection component 33, which is disposed on the first conveying component 31 and is electrically connected to the glue storage module 2. Upon detecting that the sheet 4 has entered a designated area, the detection component 33 controls the glue storage module 2 to supply 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 near the spray box 122. When the detection component 33 detects that the sheet 4 has entered the designated area, the glue storage module 2 and the glue application module 1 begin applying glue. When the detection component 33 detects that the sheet 4 has exited the designated area, the glue storage module 2 stops. Specifically, those skilled in the art can select an appropriate detection component 33 as needed, without specific limitation.

[0057] Preferably, the conveying module 3 further includes a purge component 34 , which is disposed on the first conveying component 31 and is used to purge the upper and lower surfaces of the plate 4 .

[0058] 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 horizontally extending end of the L-shaped connecting plate 3231 is connected to the outer side of the main support rod 3221, and one vertically extending end of the L-shaped connecting plate 3231 is hingedly connected to the clamping plate 3232. A first sliding groove 3235 is provided in the L-shaped connecting plate 3231 along a vertical direction. One end of the first connecting plate 3233 is disposed between the first support plate 3222 and the adjustment 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 along the width of the device. One end of the first connecting rod 3234 is hingedly connected to the clamping plate 3232, and the other end of the first connecting rod 3234 is slidably connected to the second sliding groove 3236. When the first support plate 3222 is compressed, it drives the first connecting plate 3233 downward as a whole. The first connecting rod 3234, under pressure, pulls the clamping plate 3232 to rotate, causing the clamping plate 3232 to complete the clamping action. This arrangement provides a simple and reliable overall structure. The clamping plate 3232 is triggered by the gravity of the sheet 4, allowing the clamping plate 3232 to gradually support the sheet 4 as the first support plate 3222 rotates, preventing the clamping plate 3232 from interfering with the operation of the first support plate 3222. Furthermore, this arrangement utilizes a mechanical triggering mechanism. Once an external gripper or a person grasps and lifts the sheet 4, the clamping plate 3232 releases, facilitating material removal in subsequent work sections.

[0067] The operating principle of this embodiment is as follows: a sheet 4 is delivered by external equipment or an operator to the first conveyor assembly 31, which then conveys the sheet 4 to the gluing module 1. During the conveying process, the detection assembly 33 detects that the sheet 4 has entered a designated area and activates the glue storage module 2 and the gluing module 1. The lower gluing assembly 13 applies glue to the lower surface of the sheet 4 using the glue roller assembly 131, while the sheet 4 continues to move forward. Simultaneously, the spray tank 122 of the upper gluing assembly 12 sprays glue onto the upper surface of the sheet 4, which is then evenly spread using the glue roller 121. After gluing, the sheet 4 contacts the support member 322 that gradually rotates to the upper side. 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 compressed and slides with the support main rod 3221, and transmits the pressure to the adjustment spring 3223, triggering the clamping mechanism 323 to close. After being compressed and stabilized, the height of the upper surface of the first support plate is flush with the highest point of the glue roller group 131, and the clamping is completed in the support member 322 and continues to move. When the detection component 33 detects that the sheet 4 has moved out of the designated area after the 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 and transported to the set position by the second conveying component 32, waiting to be received by external equipment or personnel.
