Description

Technical Field

[0001] This utility model relates to the field of wood door processing tools, and more specifically, it relates to an adjustable trimming knife for wood doors. Background Technology

[0002] In the process of wood door manufacturing, the edge trimming knife is an indispensable tool. It is mainly used to trim burrs and unevenness on the edges of the wood door, making it smooth and even.

[0003] For example, the patent announcement number CN220762039U discloses a cutter head and cutter bar. The cutter head includes a support plate and a blade. The outer wall of the support plate has several horizontally distributed discharge grooves and several vertically distributed unloading grooves. When the cutter bar and cutter head rotate, the blade tip trims the edge of the wooden board. Part of the generated debris is driven into the unloading groove, where it rubs against the mesh surface on the slope and is discharged by rotation. The other part is driven into the several horizontally distributed discharge grooves and is discharged from the slope through the guide groove. When the contact area between the inclined blade tip and the wooden board is large, the generated debris can be discharged in two ways.

[0004] In the above, the length of the blade is fixed and cannot be adjusted according to the length of the trimming, resulting in low flexibility. When trimming long wooden doors, the trimming speed of this blade is slow, which reduces the trimming efficiency. Utility Model Content

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.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figure 1 As shown, the adjustable trimming knife for wooden doors includes a handle 1 and a blade body 2. When the middle blade head 3 and the handle 1 are disassembled, the middle blade head 3 is rotated, and the external thread on the extension rod 9 spirals out along the internal thread in the slot 10. When the middle blade head 3 and the handle 1 are installed and fixed, the extension rod 9 is inserted into the slot 10 and rotated, and the internal and external threads are spirally fixed, so that the blade body 2 and the handle 1 can be disassembled.

[0026] Fix the middle cutter head 3 and the handle 1, and use the first bevel surface 6 on the middle cutter head 3 to trim the edge of the wooden door. When the length to be trimmed is long, a left cutter head 4 and a right cutter head 5 can be added.

[0027] The slot 12 on the left cutter head 4 and the fixing block 11 are engaged and fixed in the slot 12, thus completing the first fixed installation of the left cutter head 4 and the middle cutter head 3. At this time, the first mounting plate 15 is attached to the outer wall of the left cutter head 4. The first mounting plate 15 and the left cutter head 4 are fixed with screws, thus completing the second fixed installation of the left cutter head 4 and the middle cutter head 3, so that the first bevel surface 6 on the middle cutter head 3 and the first bevel surface 6 on the left cutter head 4 are trimmed.

[0028] Alternatively, the limiting block 13 on the right-side cutter head 5 can be inserted into the groove 14 for locking and fixing. This completes the first fixed installation of the right-side cutter head 5 and the middle cutter head 3. The second mounting plate 16 is attached to the outer wall of the middle cutter head 3, and the second mounting plate 16 and the middle cutter head 3 are fixed with screws, thus achieving the second fixed installation of the right-side cutter head 5 and the middle cutter head 3, making the connection more stable and reliable.

[0029] The height of the right cutter head 5 is greater than that of the middle cutter head 3, which is greater than that of the left cutter head 4, so that the first slope 6 on the middle cutter head 3, the left cutter head 4, and the right cutter head 5 forms a slope.

[0030] When repairing a wooden door, the connecting cutter head 7 is installed on the middle cutter head 3, the left cutter head 4, and the right cutter head 5 respectively.

[0031] First, place the connecting blade 7 on the middle blade 3. The second slope 8 on the connecting blade 7 is attached to the first slope 6 on the middle blade 3. The third mounting plate 17 is attached to the middle blade 3. The third mounting plate 17 and the middle blade 3 are fixed with screws to fix the middle blade 3 and the connecting blade 7 on the middle blade 3. The flat side of the connecting blade 7 can be used to trim the wooden door. When the length to be trimmed is longer, the opening 18 of the connecting blade 7 on the left blade 4 and the positioning block 19 of the connecting blade 7 on the middle blade 3 cooperate. The positioning block 19 and the opening 18 are engaged and fixed to fix the connecting blade 7 on the left blade 4 and the connecting blade 7 on the middle blade 3. The third mounting plate 17 of the connecting blade 7 on the left blade 4 and the left blade 4 are fixed with screws.

[0032] The connecting cutter head 7 fixing block 11 on the right cutter head 5 and the connecting cutter head 7 opening 18 on the middle cutter head 3 are engaged and fixed. The third mounting plate 17 on the connecting cutter head 7 on the right cutter head 5 and the right cutter head 5 are fixed together by screws.

[0033] The height of the left blade 4 plus the height of the connecting blade 7 equals the height of the middle blade 3 plus the height of the connecting blade 7, which in turn equals the height of the left blade 4 plus the height of the connecting blade 7. This ensures that the connecting blade 7 is on the same horizontal line when trimming the wooden door, allowing for better trimming operations.

[0034] Working principle: By setting the blade body 2, the number of middle blade head 3, left blade head 4 and right blade head 5 can be selected according to the length of trimming. The middle blade head 3, left blade head 4 and right blade head 5 can trim the bevel of the wooden door, thereby improving flexibility. When trimming the flat surface of the wooden door, the connecting blade head 7 is fixed to the middle blade head 3, left blade head 4 and right blade head 5 respectively. The connecting blade head 7 trims the wooden door at its flat surface, thereby improving trimming efficiency.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
