Description

Technical Field

[0001] This utility model relates to the field of wood production technology, and in particular to a glue injection and pressing adjustment device. Background Technology

[0002] A wood glue injection and pressing device is a specialized device designed to inject glue between wood or composite materials and apply pressure to bond these materials tightly together. This type of device is widely used in industries such as furniture manufacturing, construction, and wood processing to improve the strength and durability of products.

[0003] Currently, most wood glue injection and pressing devices can only inject and evenly apply glue to wood of a single thickness, lacking the ability to adjust for wood of different thicknesses. Although some devices are equipped with glue injection rollers and pressure rollers, which can achieve glue application and preliminary pressing to a certain extent, the inability to adjust the height makes it difficult to quickly adapt to various specifications of wood, affecting the versatility and production efficiency of the equipment.

[0004] Furthermore, during the pressing stage after glue injection, existing equipment often lacks effective positioning and clamping structures due to variations in wood width. This leads to lateral shifts or unstable positions of the wood during transport and pressing. Such shifts not only affect the uniform distribution of glue but can also result in incomplete pressing, uneven bonding strength, and even product scrap, severely impacting yield and processing quality. Utility Model Content

[0005] The purpose of this invention is to provide a glue injection and pressing adjustment device that avoids the problems of existing wood glue injection and pressing devices, which can only handle wood of a single thickness, lack height adjustment function, and are difficult to adapt to various specifications, thus affecting versatility and efficiency. Furthermore, the device is not securely positioned when clamping wood of different widths, which can easily cause the wood to shift during pressing, affecting glue uniformity and bonding quality, and thus reducing the yield.

[0006] This utility model provides a glue injection and pressing adjustment device, including a conveying device. A processing box in contact with the ground is installed on the left side of the conveying device. A glue injection assembly is provided on the left side of the conveying device. The glue injection assembly includes two fixed boxes. A movable plate is slidably connected to the surface of the two fixed boxes. A pressure roller and a glue injection roller are rotatably connected to opposite sides of the two movable plates, respectively. A bonding assembly is provided on both the front and rear sides of the processing box. A heating device in contact with the ground is installed on the left side of the processing box.

[0007] In one specific implementation, the inner cavities of the two fixed boxes are respectively connected to a first threaded rod and a sliding rod, and the surfaces of the first threaded rod and the sliding rod are movably connected to the inner side of the movable plate.

[0008] In one specific implementation, pulleys are respectively mounted on the surfaces of the pressure roller and the glue injection roller, and the two pulleys are connected by belt drive.

[0009] In one specific implementation, a first motor is fixedly connected to the top of the fixed box, and the output shaft of the first motor is fixedly connected to the top end of the first threaded rod.

[0010] In one specific implementation, a protective box is fixedly connected to the front side of the movable plate, a second motor is fixedly connected to the inner cavity of the protective box, the output shaft of the second motor is fixedly connected to the front end of the glue injection roller, welding blocks are fixedly connected to both the front and rear sides of the fixed box, and a push roller is rotatably connected to the surface of the welding block.

[0011] In one specific implementation, the bonding assembly includes two cylinders, the top of which is fixedly connected to the top of the inner cavity of the processing box, and the output end of the cylinder is fixedly connected to a pressure plate.

[0012] In one specific implementation, limit plates are fixedly connected to both the front and rear sides of the processing box, and threaded blocks are provided through both the front and rear sides of the processing box.

[0013] In one specific implementation, a guide plate is slidably connected to the top of the limiting plate, and a second threaded rod is movably connected to the surface of the guide plate.

[0014] In one specific implementation, one end of the second threaded rod is connected to a clamping plate, and a gear is fixedly connected to the surface of the threaded block.

[0015] In one specific implementation, connecting plates are fixedly connected to both the front and rear sides of the pressure plate, and a toothed plate is fixedly connected to the side of the connecting plate away from the pressure plate, and the toothed plate meshes with a gear.

[0016] The beneficial effects of this application are as follows: Through the synergistic cooperation of the glue injection component and the bonding component, not only is uniform glue injection achieved on wood of different thicknesses, but the bonding component also enables efficient and tight pressing of the wood after glue injection. During the pressing process, the clamping function of the glue injection component and the bonding component adapts to and clamps the sides of wood of different widths, effectively preventing lateral displacement or positional instability of the wood during pressing, ensuring full contact and firm adhesion of the glued surfaces. This improves the applicability and processing accuracy of the equipment, facilitates convenient operation, and promotes the continuous and precise glue injection and pressing process of wood, significantly improving production efficiency and product quality.

[0027] Existing wood gluing and pressing devices are mostly limited to processing wood of a single thickness, lack height adjustment capabilities, and are difficult to adapt to various specifications, affecting versatility and efficiency. Furthermore, the equipment often fails to securely position wood of varying widths, leading to wood shifting during pressing, affecting glue uniformity and bonding quality, and consequently reducing yield. Therefore, the inventors have developed a glue-lubricating and pressing adjustment device where the glue-lubricating component and the bonding component work together to achieve uniform glue injection and tight pressing of wood of different thicknesses. During pressing, the clamping function adapts to wood of different widths, preventing lateral shifting, ensuring strong bonding, improving processing accuracy, significantly increasing production efficiency and product quality, thereby solving the aforementioned defects.

[0028] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please refer to Figures 1 to 8 This utility model embodiment provides a glue injection and pressing adjustment device, including a conveying device 1.

A vacuum suction cup type robotic arm is installed on the front side of the conveying device 1 to facilitate the placement of materials to be bonded after glue injection into the wood. A glue injection assembly 4 is provided on the left side of the conveying device 1. The glue injection assembly 4 includes two fixed boxes 41. The bottom of the fixed boxes 41 contacts the ground. Moving plates 45 are slidably connected to the surfaces of the two fixed boxes 41. Through cavities are opened on the left and right sides of the fixed boxes 41 to facilitate the movement of the moving plates 45. On opposite sides of the processing box 2, pressure roller 48 and glue injection roller 49 are rotatably connected. Two fixed boxes 41 are fixedly connected on opposite sides to a glue storage tank, which is responsible for replenishing the surface of the glue injection roller 49. Several nozzles are installed at the bottom of the glue storage tank. Adhesion components 5 are provided on both the front and rear sides of the processing box 2. A heating device 3, in contact with the ground, is installed on the left side of the processing box 2. A belt conveyor is installed in both the processing box 2 and the heating device 3. A fixing plate is fixedly connected to the inner cavity of the processing box 2, and this fixing plate contacts the belt conveyor in the middle, thereby preventing the conveyor belt from collapsing during the wood pressing process (e.g., ...). Figure 6As shown), the inner cavities of the two fixed boxes 41 are respectively connected to a first threaded rod 42 and a sliding rod 43. The outer surface of the first threaded rod 42 is provided with an external thread. The surfaces of the first threaded rod 42 and the sliding rod 43 are movably connected to the inner side of the movable plate 45. The area of ​​the movable plate 45 in contact with the first threaded rod 42 is provided with a matching internal thread. The top and bottom ends of the first threaded rod 42 are respectively rotatably connected to the inner cavity of the fixed box 41. The surfaces of the pressure roller 48 and the glue injection roller 49 are respectively equipped with pulleys 410, and the two pulleys 410 are connected by belt drive. The top of the fixed box 41 is fixedly connected to a first motor 44. The output shaft of 44 is fixedly connected to the top end of the first threaded rod 42. A protective box 46 is fixedly connected to the front side of the moving plate 45. A second motor 47 is fixedly connected to the inner cavity of the protective box 46. The output shaft of the second motor 47 is fixedly connected to the front end of the glue injection roller 49. Welding blocks 411 are fixedly connected to both the front and rear sides of the fixed box 41. A push roller 412 is rotatably connected to the surface of the welding block 411. The bonding assembly 5 includes two cylinders 51. The top end of the cylinder 51 is fixedly connected to the top of the inner cavity of the processing box 2. A pressure plate 52 is fixedly connected to the output end of the cylinder 51. Limiting plates 53 are fixedly connected to both the front and rear sides of the processing box 2.

[0030] Please refer to Figures 2 to 8 Threaded blocks 54 are provided through the front and rear sides of the processing box 2. The area of ​​the threaded block 54 in contact with the processing box 2 is sealed. The inner cavity of the threaded block 54 is provided with internal threads. The top of the limiting plate 53 is slidably connected to the guide plate 56. The surface of the guide plate 56 is movably connected to the second threaded rod 55. The outer surface of the second threaded rod 55 is provided with external threads that are compatible with the internal threads of the threaded block 54. One end of the second threaded rod 55 is connected to the clamping plate 57. The surface of the threaded block 54 is fixedly connected to the gear 58. The front and rear sides of the pressure plate 52 are fixedly connected to the connecting plate 59. The side of the connecting plate 59 away from the pressure plate 52 is fixedly connected to the toothed plate 510. The toothed plate 510 and the gear 58 mesh with each other.

[0031] Specifically, when the wooden board passes through the push roller 412, the second motor 47 is started. The second motor 47 drives the glue injection roller 49 and the pulley 410 to rotate, and the pulley 410 drives the pressure roller 48 to rotate synchronously. In this way, the glue injection roller 49 first injects glue onto the surface of the wooden board, and then the pressure roller 48 evenly rolls and distributes the glue.

[0032] When it is necessary to adapt to wood of different thicknesses, the first motor 44 is started, which drives the first threaded rod 42 to rotate. The threaded transmission principle is used to move the moving plate 45 up and down, thereby driving the glue injection roller 49 and the pressure roller 48 to adjust their height synchronously to adapt to wood boards of different heights.

[0033] During the process of conveying the wooden board into the processing box 2, the vacuum suction cup clamp located in front of the conveying device 1 is used to position and adhere the wood. Then, the cylinder 51 is activated, which pushes the pressure plate 52 downward. During the downward movement of the pressure plate 52, the connecting plate 59 and the toothed plate 510 move synchronously. The toothed plate 510 pushes the gear 58 meshing with it to rotate. The gear 58 drives the threaded block 54 to rotate. The threaded block 54 uses the thread transmission principle to push the two clamping plates 57 to move towards each other, thereby achieving clamping and fixing of the wood on both sides and preventing positional displacement due to width differences during the pressing process.

[0034] Finally, the pressure plate 52 completes the pressing operation on the wood board, thereby efficiently and stably completing the entire glue injection and pressing process.

[0035] In summary, the working principle of the glue injection and pressing adjustment device of this utility model embodiment is as follows: the user puts the wood into the conveying device 1, and firstly, glue is injected into the surface of the wood through the glue injection component 4. After the glue is injected, the vacuum suction cup clamp on the front side of the conveying device 1 is used to place the workpiece to be bonded onto the glue injection surface of the wood. At this time, it is conveyed to the processing box 2 through the conveying device 1. The bonding component 5 is started to press the wood. After pressing, it is sent into the heating device 3 to dry the glue after bonding, which facilitates the processing of the wood.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
