Description

Technical Field

[0001] This utility model relates to the field of plywood production technology, and specifically to a high-efficiency glue application device for plywood. Background Technology

[0002] Plywood is a type of board made by bonding multiple layers of veneer together with adhesives under high temperature and pressure. It has various uses and advantages, and the plywood production process includes raw material preparation, wood chip cutting, gluing, hot pressing, edge trimming, and finishing. Among these steps, gluing is a crucial one, and efficient gluing equipment can effectively improve plywood production efficiency.

[0003] A search revealed an efficient gluing device for plywood in publication CN222537911 U. This device stacks the plywood to be glued on top of a workbench, and a conveyor mechanism pushes the plywood to the top of a connecting plate. During this movement, a glue spraying mechanism applies glue to the surface of the plywood. No manual handling is required during the application process, saving considerable time and improving work efficiency.

[0004] However, certain defects and shortcomings still exist and need to be optimized. Specific defects and shortcomings are as follows: This high-efficiency glue applicator for plywood uses a scraper sidewall that contacts the end face of the plywood. When the slider slides along the L-shaped plate, the scraper pushes the plywood through one of the connecting grooves to the right, preparing for the glue application. However, relying solely on the scraper structure to push the plywood is prone to slippage, resulting in ineffective pushing and directly affecting the orderly execution of subsequent glue application operations.

[0005] Therefore, it is particularly important to improve existing high-efficiency glue application devices for plywood and design a high-efficiency glue application device for plywood to solve the above-mentioned technical defects. Utility Model Content

[0006] The purpose of this utility model is to provide a high-efficiency glue applicator for plywood. This high-efficiency glue applicator for plywood, through the design of the plywood fixing mechanism, can fix the plywood, prevent slippage during pushing, ensure effective pushing, and facilitate the orderly development of subsequent glue application operations, thereby effectively solving the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-efficiency gluing device for plywood includes a plywood production table. A plywood conveying mechanism is provided at the bottom of the plywood production table. A plywood body is movably mounted on the top surface of the plywood conveying mechanism through a plywood fixing mechanism. The plywood fixing mechanism includes an I-beam frame. A conveying base is rotatably connected to the center of the bottom surface of the I-beam frame near the feeding end. A vacuum pump is fixedly installed at the center of the bottom surface of the I-beam frame. Suction cup frames are fixedly installed on both sides of the I-beam frame. Fixed suction cups are fixedly installed at both ends of the top surface of the suction cup frames through fixing rods. The fixed suction cups and the vacuum pump are connected through an air passage.

[0009] As a preferred embodiment of this utility model, the plywood production table is composed of a flat plate and an inclined plate, and the inclined plate is fixedly connected to the end of the flat plate near the discharge end. The bottom sides of the plywood production table are fixedly installed with a frame, and the bottom center of the plywood production table is fixedly installed with a conveying frame. The plywood production table has a through-hole conveying opening, and the I-beam frame is movably installed inside the conveying opening.

[0010] As a preferred embodiment of this utility model, the plywood conveying mechanism includes a conveyor belt, a driven pulley, a driving pulley, and a drive motor, and the conveying base is fixedly connected to the outer surface of the conveyor belt at the end face away from the I-beam.

[0011] In a preferred embodiment of this utility model, the driven pulley and the driving pulley are connected by a conveyor belt, and a drive motor is provided at one end of the driving pulley, and the output shaft of the drive motor is keyed to the driving pulley.

[0012] As a preferred embodiment of this utility model, two sets of symmetrically distributed plywood baffles are fixedly installed on the top surface of the plywood production table near both ends of the plywood body. A plywood spraying mechanism, a plywood glue roller, and a glue heating mechanism are sequentially arranged near the discharge end of the two sets of symmetrically distributed plywood baffles. An outlet adapted to the plywood body is opened at the bottom end of the set of plywood spraying mechanism.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the high-efficiency glue applicator for plywood uses a plywood fixing mechanism to secure the plywood. A vacuum pump operates, utilizing pressure difference to fix the plywood body via a suction cup, effectively preventing slippage during pushing and ensuring efficient pushing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] This utility model provides a high-efficiency glue applicator for plywood. The high-efficiency glue applicator for plywood, through the design of the plywood fixing mechanism, can fix the plywood, prevent slippage during pushing, ensure effective pushing, and facilitate the orderly development of subsequent glue application operations, thereby effectively solving the technical problems mentioned in the background art.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] A high-efficiency glue application device for plywood includes a plywood production platform 1. A plywood conveying mechanism 2 is installed at the bottom of the plywood production platform 1. A plywood body 4 is movably mounted on the top surface of the plywood conveying mechanism 2 via a plywood fixing mechanism 3. Two sets of symmetrically distributed plywood baffles 5 are fixedly installed on the top surface of the plywood production platform 1 near both ends of the plywood body 4. A plywood spraying mechanism 6, a plywood glue application roller 7, and a glue heating mechanism 8 are sequentially arranged near the discharge end of the two sets of symmetrically distributed plywood baffles 5. The plywood baffle 5 has an outlet at the bottom of a group near the plywood spraying mechanism 6 that is compatible with the plywood body 4. During the pushing process, the plywood body 4 is first led out from the outlet and passes through the plywood spraying mechanism 6, the plywood glue roller 7, and the glue heating mechanism 8 in sequence to achieve spraying, glue application, and heating of the plywood body 4, thereby achieving efficient glue application. By having an outlet at the bottom of a group near the plywood spraying mechanism 6 in two symmetrically distributed plywood baffles 5 that is compatible with the plywood body 4, the pushing of the plywood body 4 can be avoided.

[0026] The plywood fixing mechanism 3 includes an I-beam frame 31. A conveying base 32 is rotatably connected to the center of the bottom surface of the I-beam frame 31 near the feeding end. A vacuum pump 33 is fixedly installed at the center of the bottom surface of the I-beam frame 31. Suction cup frames 34 are fixedly installed on both sides of the I-beam frame 31. Fixed suction cups 36 are fixedly installed at both ends of the top surface of the suction cup frames 34 through fixing rods 35. The fixed suction cups 36 and the vacuum pump 33 are connected through an air passage 37. When the vacuum pump 33 is working, it uses the pressure difference to fix the plywood body 4 through the fixed suction cups 36, which can effectively prevent slippage during pushing, ensure effective pushing, and facilitate the orderly development of subsequent glue application operations.

[0027] Furthermore, in this embodiment, please refer to Figure 1The plywood production table 1 is composed of a flat plate 11 and an inclined plate 12. The inclined plate 12 is fixedly connected to the flat plate 11 near the discharge end. The bottom sides of the plywood production table 1 are fixedly installed with a frame 13. The bottom center of the plywood production table 1 is fixedly installed with a conveying mounting frame 14. The plywood production table 1 has a through-hole conveying opening 15. The I-beam frame 31 is movably installed inside the conveying opening 15. The design of the inclined plate 12 facilitates the automatic discharge of the plywood body 4 after gluing under the action of gravity. The design of the conveying mounting frame 14 facilitates the fixing of the components that need to be fixed in the plywood conveying mechanism 2. At the same time, it can also provide protection for the whole to prevent damage from external forces. Meanwhile, the design of the conveying opening 15 avoids obstruction to the I-beam frame 31 when pushing the plywood body 4, so as to push the gluing smoothly.

[0028] Furthermore, in this embodiment, please refer to Figure 2 The plywood conveying mechanism 2 includes a conveyor belt 21, a driven pulley 22, a driving pulley 23, and a drive motor 24. The conveying base 32 is fixedly connected to the outer surface of the conveyor belt 21 at one end away from the I-beam 31. The driven pulley 22 and the driving pulley 23 are connected by transmission through the conveyor belt 21. The drive motor 24 is provided at one end of the driving pulley 23, and the output shaft of the drive motor 24 is keyed to the driving pulley 23. When the drive motor 24 is working, the driving pulley 23 starts to rotate under the action of the output shaft, and in conjunction with the driven pulley 22, the conveyor belt 21 starts to run, driving the conveying base 32 to move from one end to the other end. After completing the push, it returns to its original position and waits for the next push.

[0029] Furthermore, in this embodiment, please refer to Figure 4 The plywood spraying mechanism 6 includes a connecting pipe 61 fixedly installed on the top surface of the plywood production table 1 and a glue box 62 fixedly installed on the plywood baffle 5. Several sets of equally spaced nozzles 63 are fixedly installed on the bottom surface of the connecting pipe 61. A glue spraying pump body 64 is fixedly installed on one end face of the glue box 62. The glue spraying pump body 64 and several sets of equally spaced nozzles 63 are connected through a glue pipe 65. When the glue spraying pump body 64 works, it transports the glue inside the glue box 62 to the connecting pipe 61 through the glue pipe 65, and sprays the plywood body 4 that passes through through several sets of equally spaced nozzles 63.

[0030] It should be noted that the plywood glue roller 7 and the glue heating mechanism 8 are both existing technologies in high-efficiency glue application devices for plywood, and will not be described in detail here.

[0031] In this embodiment, the specific implementation scenario is as follows: During the glue coating production of plywood, the vacuum pump 33 first operates, using the pressure difference to fix the plywood body 4 through the fixed suction cup 36, which can effectively prevent slippage during pushing, ensure effective pushing, and facilitate the orderly unfolding of subsequent glue coating operations. Then, the drive motor 24 operates, and at this time, under the action of the output shaft, the driving pulley 23 starts to rotate, and in conjunction with the driven pulley 22, the conveyor belt 21 starts to run. At this time, the plywood body 4 is discharged from the outlet. When passing through the plywood spraying mechanism 6, the glue spraying pump 64 operates, transporting the glue inside the glue tank 62 to the connecting pipe 61 through the glue tube 65, and through several sets of equidistant... Distributed nozzles 63 spray the plywood body 4 through it, and then it passes through the plywood glue roller 7 and the glue heating mechanism 8 in sequence to achieve spraying, glue application and heating of the plywood body 4, thereby achieving efficient glue application. After the glue application is completed, the vacuum pump 33 enters air to release the vacuum state. At this time, the pressure difference is balanced, and the end of the I-beam frame 31 away from the conveyor base 32 automatically tilts downward. At the same time, the plywood body 4 is automatically discharged on the inclined plate 12 under the action of gravity. Then, under the action of the plywood conveying mechanism 2, the conveyor base 32 returns to its original position along the original path, waiting for the next push. Moreover, compared with the existing plywood high-efficiency glue application device, it can ensure the stability of the plywood body 4 during the push.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
