Description

Technical Field

[0001] This utility model relates to the field of recycled wood production technology, specifically to a recycled low-carbon wood production line. Background Technology

[0002] Timber is one of the main reusable materials in construction projects. It is often used together with wooden formwork and is mainly used as a wooden frame. Currently, the timber used in the market is made by directly cutting strips from wooden boards. The length and size of the timber are greatly limited by the original boards. Even if waste wood strips are glued together, they cannot be used as timber because the glued wood strips rely on the adhesive force of the glue to maintain their shape. Timber produced by this simple gluing method cannot provide good support in actual use. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: A recycled low-carbon timber production line, such as Figure 1-4 As shown, the process includes a calibration frame 1 for calibrating timber 6 arranged end to end, a sanding section 2 for sanding the spliced ​​timber 6, a wrapping and hardening section 3 for coating and drying the timber 6, and a tensioning and cutting section 4. The above processing steps have been disclosed in prior patents and are considered prior art, so they will not be described again here. The sanding section 2 has multiple sanding rollers 22 arranged in parallel. The multiple sanding rollers 22 are spaced apart and are used to sand the spliced ​​timber 6. The sanding rollers 22 are distributed perpendicular to the timber 6. Each end of the sanding roller 22 has two sanding grooves 2201 for the timber 6 to pass through.

[0028] A conveying pipe 34 is provided below the grinding roller 22, and the conveying pipe 34 is used to convey the wood chips from the grinding to the area below the tensioning and cutting section 4.

[0029] In this invention, by sequentially arranging a calibration frame 1 connected end to end, a sanding section 2 for sanding the spliced ​​timber 6, a wrapping and hardening section 3 for coating and drying the timber 6, and a tensioning and cutting section 4, the spliced ​​timber 6 can be continuously sanded, wrapped, impregnated with glue, hardened, and cut. Through the above steps, the spliced ​​timber 6 is more tightly bonded to each other, enabling it to play a supporting role in construction and making fuller use of residual wood.

[0030] In addition, a receiving rack 5 is provided at the end of the tensioned slitting section 4 away from the calibration frame 1. The receiving rack 5 is used to collect the slitting timber 6.

[0031] Furthermore, the tensioning and slitting section 4 includes a tensioning part and a slitting device 41, which is used to slit the formed long strip of wood 6, and one end of the conveying pipe 34 extends directly below the slitting device 41.

[0032] By setting a conveying pipe 34 below the sanding roller 22, the sanded wood chips can be easily collected below the tensioning and cutting section 4, which facilitates subsequent cutting and collection of sanding wood chips and makes them easy to reuse.

[0033] Furthermore, a plurality of calibration rods 21 are spaced apart between the grinding section 2 and the calibration frame 1. Each calibration rod 21 has a calibration roller 211 on one side facing each other. The calibration roller 211 is used to press the wood 6. Both ends of the calibration rod 21 are set in a pointed shape. The top view projection outline of the end of the calibration rod 21 is an isosceles trapezoid shape.

[0034] By setting a calibration rod 21 between the sanding section 2 and the calibration frame 1, the arrangement angle of the spliced ​​timber 6 can be easily corrected, allowing the spliced ​​timber 6 to enter the hardened section 3 more straight. Setting both ends of the calibration rod 21 into an isosceles trapezoidal shape makes it easier for the timber 6 to enter or slide out between the calibration rods 21.

[0035] Furthermore, the wrapping and hardening section 3 includes a wrapping section and a hardening section. The wrapping section is used to wrap the mesh around the outer periphery of the spliced ​​wooden beam 6, and then the wooden beam 6 and the mesh are tightly bonded together by impregnation with glue. Wrapping mesh 31 is rotatably installed on both sides of the wrapping and hardening section 3. One end of the wrapping mesh 31 is bonded to the outside of the wooden beam 6 and continuously wraps around it as the wooden beam 6 moves.

[0036] By setting multiple wrapping meshes 31 on both sides of the hardened wrapping section 3, the meshes can rotate more smoothly during the wrapping of the timber 6, making it easier to completely wrap the outer surface of the timber 6.

[0037] Furthermore, the hardening section includes multiple impregnation boxes adapted to the cross-sectional dimensions of the timber 6. A glue tank 32 is provided above the impregnation boxes, which is used to continuously supply glue to the multiple impregnation boxes. A receiving plate 33 is provided below the glue tank 32, which is used to receive glue dripping from the timber 6 and to collect the glue.

[0038] By passing the wood 6 through the impregnation box to impregnate the wood 6 and the mesh on the outside of the wood 6, the impregnation process on the outside of the wood 6 can be completed more quickly and efficiently. By setting a receiving plate 33 below the glue box 32, the glue dripping from the wood 6 and the impregnation box can be easily collected and recycled.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
