Description

Technical Field

[0001] This utility model relates to the field of wood splicing and processing technology, and in particular to a multi-layer superimposed butterfly tenon splicing high-efficiency auxiliary feeding structure. Background Technology

[0002] In the fields of wood processing, furniture manufacturing, and some building decoration, the butterfly tenon joint is widely used due to its advantages of stable structure and natural beauty. This process achieves mechanical interlocking between boards through the wedge structure of the butterfly tenon, providing reliable connection strength without additional hardware. Therefore, it is irreplaceable in scenarios such as solid wood furniture assembly and splicing of wooden components.

[0003] However, the existing traditional butterfly tenon splicing process relies too much on manual operation. When dealing with multi-layer stacked boards, each board must be aligned and positioned manually before feeding and splicing. This process is not only time-consuming and labor-intensive, resulting in low feeding efficiency, but also the accuracy of manual positioning is significantly affected by operating experience, which can easily lead to problems such as board misalignment and mortise and tenon joint errors, resulting in quality defects such as uneven splicing gaps and insufficient structural strength.

[0004] To address this, a multi-layered, stacked butterfly tenon splicing high-efficiency auxiliary feeding structure is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency auxiliary feeding structure for multi-layer stacked butterfly tenon splicing, which can solve the problem that the existing traditional butterfly tenon splicing process relies too much on manual operation. When processing multi-layer stacked boards, it is necessary to manually align the boards one by one and complete the positioning before feeding and splicing. This process is not only time-consuming and labor-intensive, resulting in low feeding efficiency, but also the accuracy of manual positioning is significantly affected by the operator's experience, which can easily lead to problems such as board misalignment and tenon joint errors, resulting in quality defects such as uneven splicing gaps and insufficient structural strength.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer superimposed butterfly tenon splicing high-efficiency auxiliary feeding structure, including a base, a controller is provided on the front side of the base, a positioning and ejection structure is provided on the top of the base, a butterfly tenon is provided on the top of the positioning and ejection structure, and a superimposed auxiliary feeding mechanism is provided on the top of the base.

[0007] The superimposed auxiliary conveying mechanism includes a bracket welded to the rear side of the base. A hydraulic cylinder is bolted to the top of the bracket, and the telescopic end of the hydraulic cylinder passes through the top of the bracket. A lifting frame is bolted to the telescopic end of the hydraulic cylinder. Plates are provided on both sides inside the lifting frame, and tenons are formed on the inner side of the plate. Side fixing structures are provided on both sides inside the lifting frame, and the side fixing structures are located on the outer side of the plate.

The telescopic end of the electric push rod passes through the top of the lifting frame, and a pressure plate is fixedly connected to the telescopic end of the electric push rod. The pressure plate is located on the top of the plate.

[0008] Preferably, the positioning ejection structure includes a guide groove formed on the top of the base, the guide groove being located at the bottom of the butterfly tenon.

[0009] Preferably, the bottom of the guide groove is provided with a receiving groove, and a first electric telescopic rod is provided inside the receiving groove. The telescopic end of the first electric telescopic rod is fixedly connected to a carrier plate. The carrier plate is located inside the guide groove, and the top of the carrier plate contacts the bottom of the butterfly tenon.

[0010] Preferably, a support sleeve is fixedly connected to the outer side of the first electric telescopic rod, and the support sleeve is bolted to the bottom of the base.

[0011] Preferably, the side-fixing structure includes a second electric telescopic rod bolted to both sides of the lifting frame, the telescopic end of the second electric telescopic rod penetrating the outer side of the lifting frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application, by setting up a stacking auxiliary feeding mechanism, fixes the butterfly tenon to the positioning and ejection structure. The operator can then stack multiple layers of boards into the two sides inside the lifting frame, which are against the rear wall, and align the tenons. Subsequently, the controller activates the side fixing structures on both sides to push and position the boards from both sides, ensuring that the tenons are accurately and stably connected. Then, the electric push rod drives the pressure plate to press down and fix the boards. Finally, the hydraulic cylinder drives the lifting frame to descend, realizing the synchronous feeding of multiple layers of boards, so that the tenons automatically complete the locking and splicing with the butterfly tenon. This process completely replaces the traditional manual one-by-one positioning operation, greatly reduces manpower input and operation time, significantly improves feeding efficiency, and effectively solves the problems of low efficiency and high labor intensity of manual positioning of multi-layer boards.

[0017] 2. This application, by setting a positioning and ejection structure, can accurately position and stably support the butterfly tenon, fundamentally avoiding board misalignment and tenon-groove misalignment caused by manual operation, greatly improving the accuracy of the butterfly tenon and board splicing. As a result, the spliced ​​boards have uniform gaps and reliable structural strength, effectively improving product quality. In addition, after the splicing is completed, the positioning and ejection structure can also slightly push the butterfly tenon, making it easy for operators to quickly pick it up, further optimizing the overall operation process and improving work efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A multi-layer stacked butterfly tenon splicing high-efficiency auxiliary feeding structure includes a base 1, a controller 2 is provided on the front side of the base 1, a positioning and ejection structure 3 is provided on the top of the base 1, a butterfly tenon 4 is provided on the top of the positioning and ejection structure 3, and a stacked auxiliary feeding mechanism 5 is provided on the top of the base 1.

[0027] The superimposed auxiliary conveying mechanism 5 includes a bracket 51 welded to the rear side of the base 1. A hydraulic cylinder 52 is bolted to the top of the bracket 51. The telescopic end of the hydraulic cylinder 52 passes through the top of the bracket 51. A lifting frame 53 is bolted to the telescopic end of the hydraulic cylinder 52. Plates 54 are provided on both sides inside the lifting frame 53. A tenon 55 is opened on the inner side of the plate 54. Side fixing structures 56 are provided on both sides inside the lifting frame 53. The side fixing structures 56 are located on the outer side of the plate 54. Electric push rods 57 are bolted to both sides of the top of the lifting frame 53. The telescopic end of the electric push rod 57 passes through the top of the lifting frame 53. A pressure plate 58 is fixedly connected to the telescopic end of the electric push rod 57. The pressure plate 58 is located on the top of the plate 54.

[0028] In this embodiment: by setting up controller 2, positioning ejection structure 3 and stacking auxiliary conveying mechanism 5, efficient and precise splicing of multi-layer board 54 and butterfly tenon 4 is achieved. During operation, butterfly tenon 4 is first placed on positioning ejection structure 3 on top of base 1. Utilizing its precise limiting and stable support characteristics, butterfly tenon 4 is ensured to be in a fixed and standard splicing position. At the same time, the operator places the multi-layer board 54 to be spliced ​​on both sides inside the lifting frame 53, so that the tenon groove 55 on the inner side of board 54 corresponds to butterfly tenon 4 and abuts against the rear wall of lifting frame 53. At this time, the operator activates side fixing structure 56 through controller 2, which pushes from the outside of board 54, precisely moving and positioning multi-layer board 54 inward, ensuring that the tenon groove 55 of all board 54 is strictly aligned. Then, controller 2... The electric push rod 57 drives the pressure plate 58 to descend, pressing and fixing the board 54 from the top to prevent displacement of the board 54 during the splicing process. After positioning and fixing, the controller 2 controls the hydraulic cylinder 52 to start, and its telescopic end drives the lifting frame 53 to descend smoothly, so that the tenon 55 of the multi-layer board 54 can be engaged with the positioned butterfly tenon 4 synchronously and at a uniform speed. Due to the precise fixing of the butterfly tenon 4 by the positioning and ejection structure 3, and the precise limiting and stable feeding of the board 54 by the superimposed auxiliary feeding mechanism 5, the entire splicing process achieves high-precision and automated operation, effectively avoiding the problems of manual positioning deviation and unstable feeding. After the splicing is completed, the positioning and ejection structure 3 can also eject the butterfly tenon 4 for easy removal and the next splicing operation, thus forming an efficient and continuous operation process.

[0029] Specifically, such as Figure 3 As shown, the positioning ejection structure 3 includes a guide groove 31 opened on the top of the base 1, and the guide groove 31 is located at the bottom of the butterfly tenon 4.

[0030] Specifically, such as Figure 3 As shown, a receiving groove 32 is provided at the bottom of the guide groove 31. A first electric telescopic rod 33 is provided inside the receiving groove 32. A carrier plate 34 is fixedly connected to the telescopic end of the first electric telescopic rod 33. The carrier plate 34 is located inside the guide groove 31, and the top of the carrier plate 34 contacts the bottom of the butterfly tenon 4.

[0031] Specifically, such as Figure 3 As shown, a support sleeve 35 is fixedly connected to the outer side of the first electric telescopic rod 33, and the support sleeve 35 is bolted to the bottom of the base 1.

[0032] In this embodiment: By setting the positioning and ejection structure 3, before splicing, the first electric telescopic rod 33 is in a retracted state, and the carrier plate 34 is located in the receiving groove 32, reserving space for placing the butterfly tenon 4. After the operator puts the butterfly tenon 4 into the guide groove 31, the controller 2 sends a command to start the first electric telescopic rod 33, which extends and pushes the carrier plate 34 to rise vertically along the guide groove 31 until the top of the carrier plate 34 smoothly lifts the butterfly tenon 4 and accurately positions it to the splicing height. The guide groove 31 plays a lateral limiting role for the butterfly tenon 4, ensuring that it will not shift during the splicing process. After the splicing is completed, the first electric telescopic rod 33 drives the carrier plate 34 to eject the spliced ​​part out of the guide groove 31, making it convenient for the operator to quickly remove the part. Throughout the process, the support sleeve 35 provides stable support for the first electric telescopic rod 33, avoiding shaking due to force, and ensuring the accuracy and stability of the positioning and ejection action of the butterfly tenon 4.

[0033] Specifically, such as Figure 5 As shown, the side-fixing structure 56 includes a second electric telescopic rod 561 bolted to both sides of the lifting frame 53, and the telescopic end of the second electric telescopic rod 561 passes through the outside of the lifting frame 53.

[0034] Specifically, such as Figure 5 As shown, a side pressure block 562 is fixedly connected to the telescopic end of the second electric telescopic rod 561. A buffer pad 563 is bonded to the inner side of the side pressure block 562, and the buffer pad 563 is located on the outer side of the plate 54.

[0035] In this embodiment: by setting the side-fixing structure 56, after the multi-layered board 54 is placed in the lifting frame 53, the controller 2 controls the second electric telescopic rods 561 on both sides to extend synchronously, pushing the side pressure blocks 562 to move towards the board 54. The buffer pads 563 on the inner side of the side pressure blocks 562 first contact the outer side of the board 54, and provide uniform pressure through their own elastic deformation to avoid rigid compression damage to the surface of the board 54. As the second electric telescopic rods 561 continue to extend, the side pressure blocks 562 on both sides push the board 54 towards the middle, so that the tenon 55 of the board 54 is accurately aligned with the butterfly tenon 4 below, ensuring positioning accuracy. After the splicing is completed, the second electric telescopic rods 561 retract, and the side pressure blocks 562 return to their original positions, releasing the constraint on the board 54, which is convenient for picking up parts and loading the next time.

[0036] Specifically, such as Figure 5 As shown, the inner side of the cushioning pad 563 has anti-slip texture, which is in the shape of a grid.

[0037] Specifically, such as Figure 4 As shown, auxiliary rods 6 are welded to both sides of the top of the lifting frame 53, and the top of the auxiliary rods 6 penetrates through the bottom of the bracket 51.

[0038] In this embodiment: the mesh-like anti-slip texture on the inner side of the buffer pad 563 increases the friction with the surface of the plate 54, preventing the plate 54 from sliding due to force during the side pressing process, and further improving the positioning reliability. The auxiliary rod 6 at the top of the lifting frame 53 passes through the bottom of the bracket 51. When the hydraulic cylinder 52 drives the lifting frame 53 to rise and fall, the auxiliary rod 6 slides along the bracket 51, playing an auxiliary guiding role and enhancing the stability of the movement of the lifting frame 53.

[0039] Working principle: In the use of the multi-layer stacked butterfly tenon 4 splicing high-efficiency auxiliary feeding structure, firstly, the operator places the butterfly tenon 4 into the top guide groove 31 of the base 1. At this time, the first electric telescopic rod 33, which is in a retracted state, drives the carrier plate 34 to be located in the receiving groove 32, reserving space for the butterfly tenon 4. After placement, the controller 2 controls the first electric telescopic rod 33 to extend, pushing the carrier plate 34 to rise vertically along the guide groove 31, smoothly lifting the butterfly tenon 4 to the splicing height. The guide groove 31 forms a lateral limit on the butterfly tenon 4, supporting the sleeve. The first electric telescopic rod 33 is stably supported by 35 supports, ensuring that the butterfly tenon 4 is accurately positioned and does not shift during splicing. At the same time, the operator places the boards 54 to be stacked on both sides inside the lifting frame 53, so that the tenon grooves 55 on the inner side of the boards 54 are aligned and located directly above the butterfly tenon 4, achieving mutual correspondence and abutting against the rear wall of the lifting frame 53. Subsequently, the controller 2 activates the second electric telescopic rods 561 on both sides, which drive the side pressure blocks 562 to move towards the boards 54. The buffer pads 563 on the inner side of the side pressure blocks 562 generate elastic deformation. Applying uniform pressure to avoid damaging the surface of the board 54, as the telescopic end continues to extend, the side pressure blocks 562 on both sides push the board 54 towards the center, ensuring that the tenons 55 of all the boards 54 are strictly aligned. Next, the controller 2 controls the electric push rod 57 to drive the pressure plate 58 to descend, pressing and fixing the board 54 from the top to prevent displacement during splicing. After completing the above positioning and fixing steps, the controller 2 activates the hydraulic cylinder 52, whose telescopic end drives the lifting frame 53 to descend smoothly, allowing the tenons 55 of the multi-layer board 54 to align synchronously and uniformly with the positioned board. The butterfly tenon 4 is used for snap-fit. The auxiliary rod 6 at the top of the lifting frame 53 passes through the bottom of the bracket 51 and slides along the bracket 51 during the lifting process. It assists in guiding and enhances the movement stability of the lifting frame 53, further ensuring the splicing accuracy. After the splicing is completed, the telescopic end of the first electric telescopic rod 33 pushes the carrier plate 34 upward slightly to push the spliced ​​parts out of the guide groove 31 for easy removal. At the same time, the second electric telescopic rod 561 and the electric push rod 57 return to the initial position to prepare for the next loading. This forms a continuous and efficient automated splicing operation process.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
