Description

Technical Field

[0001] The utility model belongs to the field of chipping machine processing, and in particular relates to a cutter disc sealing mechanism and a long material cutting device thereof. Background Art

[0002] Wood chipping machines are mainly used to mass-produce thin chips with uniform thickness. The wood is fed into the machine through the feed port, sliced ​​by the blade inside the machine, and the chips are beaten out. The size and thickness of the chips are uniform, which is consistent with the chips produced by hand in the woodworking factory.

[0003] For example, a Chinese patent with publication number "CN105799028A" discloses a disc-type long material flaking machine, including a disc-type flaking blade assembly, including a housing and a plurality of flaking blades arranged radially, the flaking blades can rotate around the radial center, and are used to cut the log core along the axis parallel to the log core. When in use, the upper conveying assembly and the lower conveying assembly arrange the log core between them, and the log core is pressed and fixed between the upper conveying assembly and the lower conveying assembly by a press-fitting fixing device, and is conveyed to the cutting side of the disc-type flaking blade assembly, and the flaking blade rotates around the radial center, and cuts the log core along the axis parallel to the log core to obtain long strips of flaking. The flaking machine reuses the leftovers of veneer to obtain flaking chips for making wood shavings, thereby saving wood resources.

[0004] Although the above patent solves the problem of wood chip planing, in actual use, a certain gap must be left between the planer and the workbench during installation. The gap is used to prevent hard friction between the planer and the workbench, and to provide a certain space for the vibration displacement of the cutter disc during operation to avoid collision between the planer and the workbench and damage to the cutter disc. In actual work, some wood particles or large wood chips with excessive thickness will be generated during the planer cutting, which will be directly discharged through the gap and mixed in the wood chips. As a result, in the subsequent board processing, the wood particles and large wood chips with excessive thickness will damage the board press when the boards are glued and pressed, causing irreversible damage to it, seriously affecting the board processing quality and processing efficiency.

[0031] Embodiment three:

[0032] like Figures 1 to 3As shown, a long material cutting device, based on the first embodiment, the cutter disc sealing mechanism 8 also includes a support plate 801, and the side of the support plate 801 away from the cutting end face 601 is fixedly connected to the workbench 3.

[0037] In this embodiment, the cutter disc 6 is symmetrically arranged in two groups. The two groups of cutter discs 6 are coaxially rotatably connected through the rotor. A protective cover 7 is provided on the upper part of the cutter disc 6, which can play a protective role. Each group of cutter discs 6 is rotatably supported by the bearing seat 9. The cutter disc 6 is rotatably connected to the output end of the power mechanism 12 through the reducer 10 and the coupling 11. During installation, the coupling 11 is provided on both sides of the reducer 10. Since the cutter disc 6 is relatively bulky, the present embodiment adopts two groups of power mechanisms 12 to jointly drive the cutter disc 6 to rotate.

A batch of long materials are placed on the feeding mechanism 14, and the feeding mechanism 14 is started to drive the long materials to be conveyed forward. The long materials are close to the front baffle 1, and then the telescopic mechanism 5 is started. At the same time, the conveying mechanism 15 drives the feeding mechanism 14 and the long materials to move toward the cutter disc 6, so that the long materials contact the planer, and are cut into shavings. The shavings enter the discharge channel in the cutter disc 6 and are discharged from the other end face of the cutter disc 6. In this process, the thick slices and large-grained wood produced by cutting fall on the cutter disc sealing mechanism 8 to prevent them from falling directly and mixing into the shavings. Under the blocking effect of the upper sealing plate 803 and the flexible baffle 802, the planer will repeatedly cut the thick slices and large-grained wood, directly turning them into shavings or sawdust and entering the discharge channel for discharge.

[0040] The utility model greatly improves the quality of wood shavings, makes the thickness of wood shavings more uniform, avoids the appearance of large-grained wood and thick slices, and provides a basis for the subsequent production of high-quality particle boards.
