Description

Technical Field

[0001] This utility model relates to the field of wood furniture processing technology, specifically to a device for uniformly applying adhesive to cold-pressed veneers on wood furniture. Background Technology

[0002] In the cold-press veneer processing of wooden furniture, the quality of the adhesive application process directly affects the veneer effect.

[0003] A search revealed existing technology (application number: CN201721415370.7), which describes "a wood veneer bonding device." This utility model has a fixed glue application mechanism, making it impossible to adjust the glue dispensing amount according to the wood board conveying speed. This easily leads to uneven glue application, affecting the quality of subsequent veneer application. Furthermore, traditional glue application devices often suffer from unstable and inconsistent feeding components, reducing processing efficiency. They also lack effective correction mechanisms, causing the wood board to easily deviate from its path during conveying, resulting in inaccurate glue application. In addition, most devices cannot adapt to wood boards of different thicknesses, lacking versatility and flexibility, making it difficult to meet diverse processing needs.

[0004] Therefore, there is an urgent need for a cold-press veneer uniform glue application device for wooden furniture that can achieve stable and continuous conveying of wooden boards, precise correction, adaptability to wooden boards of different thicknesses, and ensure uniform glue application. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for uniformly applying adhesive to cold-pressed veneers on wooden furniture.

Guide rods are provided on both sides of the movable blocks, and the two ends of the guide rods are connected to the inner walls of the mounting plate.

[0013] As a further description of the above technical solution:

[0014] The adhesive application mechanism includes a drive motor, which is located on one side of the mounting plate and its output shaft is connected to the upper end of the transmission rod. A sliding groove is provided on one side of the upper part of the transmission rod.

[0033] Example 1:

[0034] like Figures 1 to 4 As shown in the figure, this embodiment provides a cold-press veneer uniform glue application device for wooden furniture, including mounting plates 1. Two mounting plates 1 are provided. A feeding assembly 2 is provided on one side between the mounting plates 1 for conveying wooden boards. A correction mechanism 3 is provided between the feeding assemblies 2 to prevent the wooden boards from deviating. A glue application mechanism 4 is provided on the side of the mounting plates 1 away from the feeding assembly 2 for applying glue to the wooden boards. A support plate 6 is connected to the upper surface of the mounting plate 1 near the glue application mechanism 4. A hydraulic rod 5 is provided on the upper surface of the support plate 6 for adjusting the spacing of the glue application mechanism 4. The telescopic end of the hydraulic rod 5 passes through the support plate 6 and is connected to the upper surface of the support block in the glue application mechanism 4.

[0035] In this embodiment, the feeding component 2, the correction mechanism 3, and the glue application mechanism 4 constitute a uniform glue application device for cold-pressing veneer on wooden furniture according to this application.

[0036] It should also be noted that the wood furniture gluing device in this application can be used for any type of wood that requires uniform gluing. This application does not limit the specific type of wood.

[0037] Specifically, the feeding assembly 2 includes a rotary motor 201, which is disposed on one side of the mounting plate 1 and its output shaft is connected to the drive sprocket 202. A driven sprocket 204 is disposed on one side of the drive sprocket 202, and the drive sprocket 202 and the driven sprocket 204 are connected by a chain 203.

[0038] In this embodiment, the rotary motor 201 drives the drive sprocket 202 to rotate, and the chain 203 transmits power to drive the driven sprocket 204 to rotate synchronously, providing stable power for feeding and ensuring continuous transmission power.

[0039] Specifically, the drive sprocket 202 and chain 203 are connected to one end of the feeding roller 205, and the other end of the feeding roller 205 is rotatably connected to the other side wall of the mounting plate 1.

[0040] In a preferred embodiment, the rotation of the drive sprocket 202 and the driven sprocket 204 drives the feeding roller 205 to rotate synchronously. The wooden board is placed on the feeding roller 205 and is conveyed as it rotates, thereby realizing continuous and stable conveying of the wooden board and ensuring the continuity of processing.

[0041] Example 2:

[0042] A correction mechanism 3 is provided based on embodiment 1.

[0043] Specifically, the correction mechanism 3 includes a screw 301, a correction wheel 302, and a guide rod 303. The two ends of the screw 301 are rotatably connected to the side wall of the mounting plate 1. The screw 301 has a double-ended reverse thread and the two sides of the screw 301 are threaded to movable blocks. The upper surface of the movable blocks is connected to the lower end of the correction wheel 302. Guide rods 303 are provided on both sides of the movable blocks. The two ends of the guide rods 303 are connected to the inner wall of the mounting plate 1.

[0044] In this embodiment, a knob is provided on the side of the screw 301 near the rotary motor 201 for rotating the screw 301. When the screw 301 is rotated, the movable block moves in the opposite direction along the guide rod 303, which drives the correction wheel 302 to adjust the spacing, fit the two sides of the wooden board to correct the offset, and adjust according to the width of the wooden board to prevent the wooden board from deviating from the preset path and ensure accurate glue application position.

[0045] Example 3:

[0046] An adhesive application mechanism 4 is provided based on Example 2.

[0047] Specifically, the glue application mechanism 4 includes a drive motor 401, which is located on one side of the mounting plate 1 and its output shaft is connected to the upper end of the transmission rod 405. A sliding groove is provided on one side of the upper part of the transmission rod 405.

[0048] With this configuration, the drive motor 401 rotates, driving the transmission rod 405 to rotate, providing power for the adhesive application and powering the rotation of the adhesive roller.

[0049] Specifically, a sliding bevel gear set 402 is slidably connected above the transmission rod 405. A connecting block 403 is connected to the upper surface of the sliding bevel gear set 402. The other end of the connecting block 403 is connected to the other side of the sliding bevel gear set 402. A rotating bevel gear set 404 is provided below the transmission rod 405. The other side of the rotating bevel gear set 404 and the sliding bevel gear set 402 are connected to a glue applicator roller 406. A support block is provided above the glue applicator roller 406. The lower end of the support block is connected to both sides of the glue applicator roller 406 and the support block slides in the grooves on the mounting plates 1 on both sides.

[0050] The connecting block 403 is L-shaped and connected to the surfaces of the sliding bevel gear set 402 on both sides. The support block is U-shaped. The transmission rod 405 drives the sliding bevel gear set 402 and the rotating bevel gear set 404 to rotate, which drives the glue-applying roller 406 to rotate. The support block moves up and down along the slide groove with the hydraulic rod 5 to adjust the height of the glue-applying roller 406, so as to realize the glue-applying roller to rotate and apply glue. It can be adapted to wood boards of different thicknesses and ensure sufficient glue contact.

[0051] Specifically, a glue tank 7 is provided below the glue application roller 406 connected to the rotating bevel gear set 404. The glue application roller 406 is attached to the upper surface of the glue tank 7, and a glue injection port 701 is provided at one end of one side of the glue tank 7.

[0052] In this embodiment, the glue tank 7 stores glue, and the surface of the glue roller 406 picks up glue when it rotates, providing a continuous supply of glue for glue application and ensuring the continuity of glue application.

[0053] In actual use, firstly, the glue is poured into the glue tank 7 through the glue inlet 701. Then, the screw 301 is rotated, causing the movable blocks connected to the threads on both sides of the screw 301 to move the alignment wheel 302 away from or closer to it. At this time, the guide rods 303 on both sides of the movable blocks provide guidance. Then, the rotary motor 201 is started, and the output shaft of the rotary motor 201 drives the drive sprocket 202 to rotate. Due to the meshing relationship, the drive sprocket 202 drives the chain 203 to rotate, thereby driving the driven sprocket 204 on the other side of the chain 203 to rotate. Then, the drive sprocket 202 and the driven sprocket 204 drive the feeding roller 205 to rotate. After that, the wooden board is placed on the feeding roller 205 connected to the drive sprocket 202. The rotation of the feeding roller 205 drives the wooden board to move. After being aligned by the alignment wheel 302, it reaches above the feeding roller 205 connected to the driven sprocket 204. At the same time, the drive motor 401 is started, and the output shaft of the drive motor 401 drives the transmission rod. Rotation of 405 drives the sliding bevel gear set 402 and the rotating bevel gear set 404 to rotate. Due to the meshing relationship, the sliding bevel gear set 402 and the rotating bevel gear set 404 respectively drive the connected glue-applying roller 406 to rotate. At this time, the glue tank 7 below the glue-applying roller 406 connected to the rotating bevel gear set 404 is filled with glue. The rotation of the glue-applying roller 406 makes the surface evenly coated with glue. Then, the hydraulic rod 5 is activated. The telescopic end of the hydraulic rod 5 pushes the support block above the transmission rod 405 connected to the sliding bevel gear set 402 to rise and fall along the slide groove above the mounting plate 1, thereby driving the sliding bevel gear set 402 and the connecting block 403 to rise and fall, so that the two transmission rods 405 move closer or further apart to adjust the distance. Then, the feeding roller 205 connected to the driven sprocket 204 rotates, driving the wooden board above to move. Then, the wooden board enters between the transmission rods 405 for glue application. After the glue application is completed, it is discharged from the other side.

[0054] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
