Description

Technical Field

[0001] This utility model relates to the field of finger-jointed board processing technology, specifically a high-efficiency finger-jointed splicing device for small solid wood materials. Background Technology

[0002] Finger-jointed boards are solid wood boards made by vertically splicing multiple pieces of wood with serrated joints. They are named for the resemblance of interlocking fingers. Finger-jointed boards have the same uses as plywood, but they use much less glue in the production process, making them a more environmentally friendly board. More and more people are choosing finger-jointed boards to replace plywood.

[0003] Currently, the production of finger-jointed boards requires a splicing device. A search revealed a splicing machine for processing finger-jointed boards, with announcement number CN220840648U. This machine places the finger-jointed boards on a conveyor belt, which transports them to a mounting frame. A cylinder is activated, driving a push rod that pushes a connecting rod, causing a limiting plate to move and push the finger-jointed board onto a support plate. The finger-jointed board then abuts against the support plate, thus limiting its position between the limiting plate and the support plate. This prevents the finger-jointed board from moving during pressing, avoiding misalignment during splicing.

[0004] However, the above technical solutions still have the following problems when applied:

[0005] 1. Finger-jointed boards are transported via conveyor belts. Since conveyor belts are mostly made of flexible materials, the finger-jointed boards tend to sink at the conveyor belt due to the weight of the finger-jointed boards and pressure plates.

[0006] 2. When the width of the finger joint plate changes, it is difficult to achieve the centering and limiting of the finger joint plate and the feeding end of the splicing device by relying solely on the displacement of the limiting plate, which can easily affect the processing quality of the finger joint plate.

[0007] To address this issue, the present invention provides a high-efficiency finger-jointed splicing device for small solid wood pieces. Utility Model Content

[0041] The support frame 3 is fixedly connected to the base 1 on the side near the entrance of the splicing machine body 2. Multiple support rollers 4 are rotatably connected to the inner side of the support frame 3.

[0044] Two uprights 9 are fixedly connected to the two sides of the top of the assembly frame 6 respectively. A limit component 10 is provided between the two uprights 9. The limit component 10 is used to correct the deviation of the plate.

[0046] Cutting unit: Used to cut timber into short pieces of the required length and width;

[0047] Finger joint processing unit: used to cut finger-shaped grooves and protrusions on the end face of short timber, usually containing multiple sets of tools and control system;

[0049] Adhesive application system: Used to apply adhesive to the finger joints to ensure the stability of the joint;

[0050] Control system: Used to enable the linkage of various mechanisms;

[0051] In summary, the main body 2 of the panel assembly machine is a mature existing technology, and will not be elaborated further here;

[0052] In this embodiment, the support frame 3 is U-shaped, and a carrier plate 27 is fixedly connected to the top of the inside of the support frame 3. The carrier plate 27 is provided with multiple clearance grooves, and the multiple clearance grooves correspond to multiple carrier rollers 4 respectively.

[0053] More specifically, through the structural cooperation of the support frame 3, both ends of the support roller 4 can be assembled at the support frame 3, thereby forming a stable support for the support roller 4. In addition, with the setting of the carrier plate 27, the gap between two adjacent support rollers 4 can be compensated to ensure the stability of the plate conveying.

[0054] In this embodiment, the support frame 5 is fixedly connected to the inner side of the light rod 28, and the assembly frame 6 is also slidably connected to the outer side of the light rod 28.

[0055] More specifically, the mounting bracket 6 has through holes at both ends near the light rod 28, corresponding to the light rod 28, so that the mounting bracket 6 and the light rod 28 can be stably assembled. In order to reduce the friction between the light rod 28 and the mounting bracket 6, a linear bearing can be provided between the through hole and the light rod 28.

[0059] Example 2:

[0060] Please see Figure 1-5 This embodiment provides a technical solution based on Embodiment 1: In this embodiment, the limiting component 10 includes:

[0061] Linear guide rod 15 is fixedly connected between the top ends of two uprights 9. Both ends of the linear guide rod 15 are slidably connected to limit plates 16. The two limit plates 16 are rotatably connected to a linkage plate 17 on the side that is close to each other.

[0062] Positioning plate 18 is fixedly connected to the middle of linear guide rod 15. A support shaft rod 19 is fixedly connected to the middle of the top of positioning plate 18. A guide plate 20 is rotatably connected to the outer side of support shaft rod 19. The ends of two linkage plates 17 away from the limiting plate 16 are rotatably connected to the two ends of guide plate 20 respectively.

[0063] Locking component 21 is assembled in the middle of one of the uprights 9 and is used to lock the position of the limiting plate 16;

[0064] In this embodiment, the bottom ends of the two limiting plates 16 that are close to each other are provided with multiple assembly holes, and each assembly hole is movably connected with a guide ball 29.

[0065] More specifically, the guide ball 29 is mounted through the mounting hole. During the finger joint plate conveying process, the guide ball 29 can move adaptively within the mounting hole by contacting the finger joint plate, thereby reducing the friction between the limiting plate 16 and the finger joint plate and ensuring the conveying effect of the finger joint plate.

[0066] In this embodiment, mounting ears are fixedly connected to the sides of the two limiting plates 16 that are close to each other. Rotating shafts are provided in the middle of the mounting ears and at both ends of the guide plate 20, and the linkage plate 17 is connected between the two corresponding rotating shafts.

[0067] More specifically, by setting up the support ears and the rotating shaft, the linkage plate 17 can be effectively assembled from both ends, ensuring the stability and smoothness of the transmission between the linkage plate 17 and the limit plate 16 and the guide plate 20.

[0068] In this embodiment, the locking component 21 includes:

[0069] The support cylinder 22 is fixedly connected to the middle of one of the uprights 9. The guide plate 20 is slidably connected to the middle of the displacement rod 23, and one end of the displacement rod 23 is fixedly connected to one of the limiting plates 16.

[0070] Storage tube 24 is fixedly connected to the top of support tube 22. The top of storage tube 24 is threadedly connected to transmission screw 25. One end of transmission screw 25 located inside storage tube 24 is fixedly connected to stop block 26.

[0071] In this embodiment, an anti-slip pad is fixedly connected to the bottom end of the stop block 26, and the anti-slip pad is made of flexible material. By setting the anti-slip pad, the anti-slip pad can contact the displacement rod 23 during the downward movement of the stop block 26. As the stop block 26 continues to move downward, the anti-slip pad can stick tightly to the displacement rod 23, thereby positioning the limiting plate 16 by locking the displacement rod 23.

[0072] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0073] Working principle: First, the finger joint plate to be processed is placed on the top of the carrier plate 27. Then, the hydraulic cylinder 7 is started to push the assembly frame 6 down until the conveyor roller 11 contacts the finger joint plate. At the same time, the drive motor 14 is started to drive the conveyor roller 11 connected to it to rotate. With the help of the chain, the power of the drive motor 14 can be transmitted, causing the two conveyor rollers 11 to rotate in the same direction. Since the finger joint plate is located between the conveyor roller 11 and the carrier roller 4, when the conveyor roller 11 rotates, it will be conveyed to the main body 2 of the splicing machine under the limit of the limiting plate 16.

[0074] The rotatable transmission screw 25, connected to the storage cylinder 24, allows the transmission screw 25 to drive the stop slider 26 to move vertically. When the stop slider 26 disengages from the displacement rod 23, the displacement rod 23 can be unlocked. Then, pulling or pushing any of the limiting plates 16 will cause the limiting plate 16 to move under the limit of the linear guide rod 15. Since the linkage plate 17 is connected between the limiting plate 16 and the guide plate 20, when the limiting plate 16 moves, the linkage plate 17 can push the guide plate 20 to rotate under the support of the support shaft rod 19. With the rotation of the guide plate 20, the other linkage plate 17 is pulled, causing the other limiting plate 16 to move synchronously, adjusting the distance between the two limiting plates 16 to adapt to finger joints of different widths.

[0075] Then, the transmission screw 25 is rotated to cause the stop block 26 to move down until the stop block 26 is in close contact with the displacement rod 23. This increases the friction force and locks the position of the limit plate 16. The two limit plates 16 are moved synchronously so that the adjusted finger joint plate is still in the center of the support frame 3, avoiding deviation between the finger joint plate and the feed end of the splicing machine body 2.
