Description

Technical Field

[0001] This utility model belongs to the field of woodworking machinery technology and relates to a centering and feeding device for wood core milling. Background Technology

[0002] After rotary cutting of wood segments, the remaining wood core has a small diameter and low utilization rate. To make full use of wood resources, the wood core is planed into square strips and then spliced ​​into boards. Currently, there is a wood core planing machine (authorization announcement number: CN210389514U) used to plan and mill wood cores into square strips. It mainly uses upper and lower planing blades to first plan the top and bottom of the wood core into flat surfaces. Then, it passes through four upper pressure rollers and two lower pressure rollers to press the planed wood strips to the left and right planing blades. The left and right planing blades plan the left and right sides of the wood strips into flat surfaces, finally obtaining rectangular wood strips. During the use of this wood core planing machine, the wood strips are deformed by the downward pressure of the first upper pressure roller. The wood strips collapse and hit the bottom of the platform below, causing feeding problems. Some wood strips with an arched shape are even more problematic. When passing between the second and third upper pressure rollers, the middle of the wood strip is in an elevated state, which happens to avoid the two lower pressure rollers below, causing the wood strip feeding to stop. Utility Model Content

[0003] This utility model provides a wood strip milling and feeding device to solve the problems of poor wood strip feeding and feeding stagnation in existing wood core milling machines.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A frame comprising a longitudinal milling cutter roller group, a transverse milling cutter roller group, an upper feeding roller, and a feeding bracket. The upper feeding roller is located between the longitudinal and transverse milling cutter roller groups. An upper feeding cylinder is provided between the frame and the upper feeding roller. The upper feeding roller is hinged to the feeding bracket via a connecting plate. The cylinder body of the upper feeding cylinder is hinged to the feeding bracket, and the telescopic rod of the upper feeding cylinder is hinged to the upper feeding roller. The frame also includes a lower feeding roller and a lower feeding cylinder. The lower feeding roller is located below the upper feeding roller and is connected to the upper feeding bracket via a connecting plate. The frame is hinged together, and the cylinder body of the lower feeding cylinder is hinged to the frame. The telescopic rod of the lower feeding cylinder is hinged to the lower feeding roller. The longitudinal milling roller group mills the top and bottom of the wood core to obtain a wood strip with flat top and bottom surfaces, which is then fed between the upper feeding roller and the lower feeding roller. The upper feeding cylinder presses the upper feeding roller down to contact the top surface of the wood strip, and the lower feeding cylinder lifts the lower feeding roller up to contact the bottom surface of the wood strip. The wood strip with flat top and bottom surfaces is smoothly transported to the transverse milling roller group by the simultaneous pressing of the upper and lower feeding rollers. The transverse milling roller group then planes the left and right sides of the wood strip to obtain a rectangular wood strip.

[0005] A more specific technical solution than the above-mentioned technical solution may be: the frame is provided with four upper feeding rollers, and each upper feeding roller is provided with a lower feeding roller below it.

[0006] Furthermore, the frame is also equipped with an exhaust hood, which covers the longitudinal milling cutter roller group and is used to remove the wood chips generated by the longitudinal milling cutter roller group during milling of the upper and lower surfaces of the wood core.

[0007] Furthermore: The feed end of the frame is provided with a feed bracket, a feed cylinder, an upper feed roller, and a lower feed roller. The cylinder body of the feed cylinder is hinged to the feed bracket. The telescopic rod of the feed cylinder is hinged to the upper feed roller. The upper feed roller is hinged to one end of an upper connecting rod. The other end of the upper connecting rod is provided with an upper sector gear and hinged to the feed bracket. The lower feed roller is located below the upper feed roller. The lower feed roller is hinged to one end of a lower connecting rod. The other end of the lower connecting rod is provided with a lower sector gear and is hinged to the feeding bracket. The upper sector gear meshes with the lower sector gear. When the feeding cylinder controls the upper feeding roller to descend, the upper connecting rod drives the upper sector gear to rotate counterclockwise. The lower sector gear meshing with the upper sector gear drives the lower connecting rod to rotate clockwise. The lower connecting rod lifts the lower feeding roller upward. The upper feeding roller and the lower feeding roller clamp and convey the wood core to the longitudinal milling cutter roller.

[0008] Furthermore: The machine frame is equipped with a discharge bracket, an upper discharge roller, an upper discharge cylinder, a lower discharge roller, and a lower discharge cylinder at the material handling end. The upper discharge roller is hinged to the discharge bracket via a connecting plate. The cylinder body of the upper discharge cylinder is hinged to the discharge bracket, and the telescopic rod of the upper discharge cylinder is hinged to the upper discharge roller. The lower discharge roller is located below the upper discharge roller and is hinged to the machine frame via a connecting plate. The cylinder body of the lower discharge cylinder is hinged to the machine frame, and the telescopic rod of the lower discharge cylinder is hinged to the lower discharge roller. The upper discharge cylinder presses the upper discharge roller downwards to contact the top surface of the rectangular wooden strip, and the lower discharge cylinder lifts the lower discharge roller upwards to contact the bottom surface of the rectangular wooden strip. The rectangular wooden strip is simultaneously pressed and fed by the upper and lower discharge rollers, allowing it to be smoothly transported out.

[0009] Furthermore: a feeding channel is provided between the longitudinal milling cutter roller group and the transverse milling cutter roller group, and a discharge channel is provided between the transverse milling cutter roller group and the lower discharge roller.

[0010] Due to the adoption of the above technical solution, this utility model has the following beneficial effects compared with the prior art: when the upper feeding roller presses down on the wood strip, the lower feeding cylinder lifts the lower feeding roller up to contact the bottom surface of the wood strip, ensuring that the wood strip will not drag on the platform below. Moreover, the lifted lower feeding roller can also contact the bottom surface of the arched wood strip, effectively solving the problems of the wood strip being deformed by the upper feeding roller and the feeding of the arched wood strip being stagnant.
