Description of the new type ... [Technical field to which the new type belongs] This creation is about a kind of grinding equipment, especially an automatic sanding device for the surface of wood workpieces. [Previous technology] After the general wood workpiece is made, the surface must be ground before further painting. Therefore, sanding the wood surface is an indispensable process for wood products. However, because wood has its specific fiber growth direction, after the wooden products are made, there will be obvious processing knife marks on the surface of the workpiece and fibers protruding, resulting in uneven surfaces. Most of the solutions will use abrasive belts or sandpaper to remove knife marks and protruding fibers to make the surface of the workpiece flat and smooth. However, since the general sanding is done manually, it takes more time. In addition, after removing the protruding fibers, it is necessary to rely on human labor for further grinding and polishing, so the processing time required for processing is longer. Although it is also possible to process wood workpieces with a processing machine, since most of the processing machines are operated by humans, it is impossible to turn wood into automatic mining, especially for curved parts or uneven I-thickness parts. It is troublesome, so it is also time-consuming and labor-intensive in operation. In addition, most of the currently designed guarding machines are for surface grinding or surface polishing. For protruding parts of wooden guards_Wood Fiber—No suitable processing machine can be used, so this creation is provided—a kind of effective removal Wood fiber processing equipment M275056 [New content] The main purpose of this creation is to provide a kind of sand grinding machine, which is a processing equipment with automatic processing to remove the guard blade marks and wood fiber on the surface of wood workpieces. According to the purpose and effect disclosed in this creation, it is mainly equipped with a grinding group with sanding and grinding effect on a machine. The grinder has a sanding belt. The grinding direction of the sanding belt is perpendicular to the moving direction of the wood workpiece. When the abrasive belt is in contact with the wood workpiece, the knife marks and the fiber filaments on the surface of the workpiece can be abraded without damaging the surface of the workpiece. In the following, based on the purpose, effect, and structural configuration disclosed in this creation, a preferred embodiment is described in detail in conjunction with the drawings. [Embodiment] Generally, a surface processing program for a wood workpiece includes at least a knife mark grinding program, a surface grinding program, and a polishing grinding program. The knife mark grinding program is mainly used to remove the machining knife marks on the surface of wood workpieces and wood fibers protruding on the work surface due to processing, and to smooth the flat surface caused by cutting processing. The grinding equipment designed for this creation is used in this process. As shown in the first figure, a sanding grinding device (20) includes a machine (22) and a group of knife mark grinding groups (24). The knife mark grinding group (24) is set on the machine. On (22). Please refer to the fourth figure for cooperation. The knife mark grinding group (24) includes two opposite abrasive belts (30). It is worth noting that the wood workpiece (90) passes between two relative > ^ strips (30). M275056 In addition, please refer to the second figure (A), the knife mark grinding group (24) is equipped with a stretching element (40) for adjusting the tension of the second abrasive belt (30). The telescopic element (40) may be a pneumatic cylinder. Please also refer to the second figure (B), a telescoping element (42) is provided between the two opposite bases (25) of the knife mark grinding group (24), when the workpiece enters between the two opposite abrasive belts (30). Can make the opposite two base bodies (25) and abrasive belts (30) cooperate with the telescopic element (42) to be separated or approached automatically. Please refer to the first and second figures (A) again. The sanding and grinding equipment (20) is provided with two sets of automatic feed rollers (26) and (28). The two feed roller groups (26) and (28) are respectively arranged on opposite sides of the knife mark grinding group (24). Please refer to the third figure. The sanding grinding equipment (20) disclosed in this creation can be divided into two sets of knife mark grinding groups (24) and (23). Two sets of knife-mark grinding groups (24) and (23) are arranged one behind the other. The configuration of one knife-mark grinding group (24) is as described above, while the other knife-mark grinding group (23) is configured with the aforementioned knife. The mark grinding group (24) is equivalent. However, if the knife mark grinding group (24) performs a vertical grinding process, the other knife mark grinding group (23) provides a horizontal grinding process. Please refer to the fourth picture 'The fiber of general wood runs along the length of the wood, so when a wood work (90) moves horizontally and passes through the two abrasive belts of the knife mark grinding group (24) (30), the surfaces of the left and right sides of the wood workpiece (90) will achieve the sanding and grinding effect due to the upward (or downward) movement of the abrasive belt (30). Furthermore, the vertical grinding effect of s' on the left and right surfaces of the wood workpiece (90) can just remove the machining knife marks and fiber filaments on the surface of the workpiece (90). Please refer to the first and fourth figures, in order to ensure that the abrasive belt (30) is in contact with the surface M275056 of the workpiece (90), a master (21) is provided inside the abrasive belt (30) correspondingly. When the workpiece (90) passes between the abrasive belts (30), each master mold (21) acts as a backstop for each abrasive belt (30), so that the abrasive belt (30) is surely in contact with the surface of the workpiece (90). The above-mentioned wood workpiece (90) can be automatically moved by the feeding roller group (26) arranged in front of the knife mark grinding group (24). After the wood workpiece (90) is processed by the knife mark grinding group (24), please refer to the fifth figure, and the wood workpiece (90) may enter another knife mark grinding group (23). The abrasive belt (32) provided in the knife mark grinding group (23) is in contact with the upper and lower surfaces of the wood workpiece (90), and provides a horizontal grinding effect. In this way, the processing knife marks and fiber filaments on the upper and lower surfaces of the wood workpiece (90) can be removed by the abrasive belt (32). From the above, it can be known that the grinding direction provided by the knife mark grinding groups (24) and (23) of the sanding grinding equipment (20) is perpendicular to the moving direction of the wood workpiece (90), so it can be smoothly removed by grinding. Machining tool marks and fiber filaments on the surface of the workpiece. From the above design, it can be known that this creation can make the machining tool marks on the surface of the wood workpiece (90) obtain obvious sanding and grinding effect, and all can be fully under the action of the feed rollers (26), (28). Automatically completed, so not only can significantly reduce the processing time, and can make the processing effect as complete and good as expected, so it has a significant benefit to the next processing program. Referring to the sixth figure, a linear sliding device (92) may be provided on the bottom surface of the knife mark grinding group (22). The linear slide device (92) uses a linear slide seat (94) and the knife mark grinding group ( 22) In combination, when machining a workpiece (91) with curvature, the knife mark grinding group (22) and the linear slide (92) can move left and right according to the curvature of the workpiece (91). So that the abrasive belt (25) can surely contact the surface of the workpiece (91). The above implementation is an example of the effectiveness of Mi Benlin's technology, not to limit this creation. Anyone who is familiar with this technology can modify and change the above-mentioned facts without violating the technical principles of this creation and the love of Lion. Therefore, the scope of protection of the rights of this creation should be listed in the scope of patent application described later .
