Description

Technical Field

[0001] The utility model relates to the technical field of wood cutting, in particular to a saw blade for wood decoration. Background Art

[0002] In the production of solid wood furniture, logs need to be cut. During the log cutting process, a sawing machine is used to cut the wood. During the wood cutting process, the saw blade rotates at high speed and there is great friction between the saw blade and the wood, causing the saw teeth to overheat and even cause the saw teeth to soften and break.

[0003] Most saw blades currently use a complete disc structure. Since the teeth may partially break during the cutting process, once a tooth breaks, the entire saw blade must be replaced, and the remaining saw blade can only be discarded as waste, resulting in waste. In order to address the problems existing in the existing technology, we propose a saw blade for wood decoration. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example: See Figure 1-6 The present utility model provides a technical solution: a saw blade for wood finishing. This solution addresses the problem that most current saw blades utilize a complete circular disc structure. Due to the tendency for some teeth to break during the cutting process, the saw blade must be completely replaced once a tooth breaks, and the remaining blade must be discarded as waste, resulting in waste. The specific solution is as follows: the saw blade comprises a movable plate 1, a fixed plate 2, a linkage assembly 4, and an adjusting screw 12. A cutting assembly 3 is disposed between the movable plate 1 and the fixed plate 2, and is capable of cutting wood. The fixed plate 2, movable plate 1, and cutting assembly 3 are all fixedly mounted on the linkage assembly 4.

[0026] Furthermore, the fixing plate 2 is provided with an annular guide member 23, and an interference strip 22 is provided between adjacent guide members 23. The interference strip 22 has a trapezoidal cross-section and is provided between adjacent cutting blades 31. The provision of the interference strip 22 makes it easier to snap-fit and install the cutting assembly 3. The interference strip 22 can be made of hard rubber, which can effectively prevent contact wear between adjacent cutting blades 31 (mentioned below).

[0027] Furthermore, the guide member 23 includes guide rods 231 arranged in a triangular pattern. The movable plate 1 is provided with blind slots for receiving the guide rods 231. The triangular pattern of the guide rods 231 can secure the position of the cutting assembly 3, and the triangular pattern can improve the stability of the cutting assembly 3 on the fixed plate 2.

[0028] See also Figure 2Among them, the linkage component 4 includes a linkage shaft 41, a limiting block 42 is arranged in a ring shape on the outside of the linkage shaft 41, a limiting groove 21 is provided in a ring shape on the fixed plate 2, and the limiting block 42 is movably connected to the limiting groove 21. By the limiting block 42 being stuck in the limiting groove 21, the relative rotation of the linkage shaft 41 and the fixed plate 2 can be effectively limited.

[0029] Furthermore, thread grooves 43 are provided at the ends of the linkage shaft 41 corresponding to the fixed plate 2. The end of the linkage shaft 41 is in movable contact with the movable plate 1, and the centers of the linkage shaft 41 and the adjustment screw 12 are collinear. The adjustment screw 12 is threadedly connected to the thread groove 43. By limiting the adjustment screw 12, the distance between the movable plate 1 and the fixed plate 2 can be minimized, thereby stably fixing the position of the cutting assembly 3.

[0030] See also Figure 3 and Figure 4 The cutting assembly 3 includes cutting blades 31 made of diamond. Adjacent cutting blades 31 are arranged in a ring-like pattern and each has a slot for receiving the guide rods 231. The cutting blades 31 protrude from the exterior of the fixed plate 2 and the movable plate 1 and are positioned between the two plates. The length of the guide rods 231 protruding from the cutting blade 31 is less than the depth of the slot in the corresponding guide rod 231. The cutting assembly 3 is movably mounted on the fixed plate 2, with the centers of the cutting assembly 3, fixed plate 2, and movable plate 1 collinear.

[0031] In this embodiment, a snap-in block 11 is provided in the middle of the fixed plate 2 in an annular shape, and a plug-in slot 14 is provided in the movable plate 1. The snap-in block 11 is movably connected within the plug-in slot 14. An adjusting screw 12 passes through and is threadedly connected to the movable plate 1 and the linkage shaft 41. The adjusting screw 12 and the movable plate 1 are rotationally connected via a rotating bearing 13. The forward screwing direction of the adjusting screw 12 is the same as the rotation direction of the linkage shaft 41. With the snap-in block 11 movably connected within the plug-in slot 14, the relative rotation of the movable plate 1 and the fixed plate 2 can be restricted, further improving the linkage between the fixed plate 2, movable plate 1, and cutting assembly 3, and facilitating the wood cutting process.

[0032] Working principle: During use, if part of the cutting disc 31 of this type of wood decoration saw blade is broken, the adjusting screw 12 can be rotated in the reverse direction so that the adjusting screw 12 drives the movable plate 1 to gradually move away from the fixed plate 2. At this time, the distance between the fixed plate 2 and the movable plate 1 increases, and the cutting disc 31 can be removed from the guide rod 231 on the fixed plate 2. The broken cutting disc 31 can be replaced without replacing the entire cutting assembly 3, thereby avoiding unnecessary waste. After the replacement is completed, the adjusting screw 12 is rotated forward and the adjusting screw 12 is screwed into the linkage shaft 41. At the same time, the adjusting screw 12 drives the movable plate 1 to gradually approach the fixed plate 2. At this time, the distance between the fixed plate 2 and the movable plate 1 is reduced, so that the cutting assembly 3 can be stably fixed between the fixed plate 2 and the movable plate 1, which is more convenient for wood cutting and processing needs.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
