DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. The utility model will be further described in combination with the drawings and embodiments:

[0019] As Figures 1-4 shown in the figure, a multi-blade saw for wood processing, comprising a base 1, the base 1 is fixed with a first conveying belt 3 and a second conveying belt 4 for conveying wood board, the base is fixed with a frame body 2, a plurality of circular saw blades 5 are arranged side by side on the frame body, the circular saw blades 5 are located directly above the transition of the first conveying belt and the second conveying belt, the tangent direction of the circular saw blades is parallel to the walking direction of the wood, the inlet end of the frame body 2 is provided with a wood positioning mechanism 6, the wood positioning mechanism 6 comprises a positioning rod 61, a positioning roller 62 and a lifting rod 63, the positioning roller 62 is rotatably connected to the positioning rod 61, the axis of the positioning roller 62 is perpendicular to the running direction of the wood, the two ends of the positioning rod 61 are fixedly connected with the lifting rod 63, the lifting rod 63 passes through the top plate 66 and is limited by the first limiting block 65, the spring 64 is arranged on the lifting rod 63 between the top plate 66 and the positioning rod 61.

[0020] The first conveying belt 3 and the second conveying belt 4 in the application are responsible for stably conveying the wood board to be processed to the saw blade and conveying the wood board out after processing, realizing the automatic and continuous production process. Among them, the wood positioning mechanism 6 can ensure that the wood is accurately positioned before entering the saw blade, avoiding cutting deviation. The spring 64 enables the positioning roller 62 to adaptively adjust according to the thickness and hardness of the wood, improving the versatility and flexibility of the equipment.

[0021] Wood is placed on the second conveyor belt 4, wood from the import end into the multi-blade saw, under the action of wood positioning mechanism 6, wood will always move forward along the straight direction, and cutting in the multi-blade saw. Because the wood is transported forward, the positioning roller 62 is always in contact with the wood rolling, so even if the wood is not inclined when the circular saw blade 5 is cutting.

[0022] Because of the rolling friction between the wood and the positioning roller, compared with the prior art, the energy loss can be reduced while ensuring the compression and positioning, and the wood surface will not be damaged.

[0023] Further, the top plate 66 is fixed with the frame 2, the first through hole 661 is arranged on the frame 2, and the lifting rod 63 is in sliding connection with the first through hole 661. The two sides of the top plate 66 are respectively fixed with side plates 67, the sliding holes 671 are vertically arranged on the side plates 67 in the vertical direction, and the two ends of the positioning rod 61 pass through the sliding holes 671 and are limited by the second limiting block 68.

[0024] In order to avoid scratching or damaging the surface of the wood, the outer part of the positioning roller 62 is wrapped with a rubber cylinder 69, and the outer surface of the rubber cylinder 69 is provided with anti-skid lines 691. The arrangement of the anti-skid lines 691 can improve the friction between the positioning roller 62 and the wood, so that the wood can pass through the saw blade more stably.

[0025] Because a large amount of wood chips will be left on the conveyor belt during the wood processing, the wood chips will also cause the wood to deviate on the conveyor belt. Therefore, the cleaning assembly 7 is arranged at both ends of the base 1, which is used for cleaning the wood chips left on the conveyor belt, so that the wood is in direct contact with the conveyor belt. Specifically, the cleaning assembly 7 is located below the first conveyor belt 3 and the second conveyor belt 4, and the cleaning assembly 7 comprises a cleaning roller 71. The rotating direction of the cleaning roller 71 is opposite to the running direction of the conveyor belt, so that the wood chips and sundries falling on the conveyor belt can be removed in time during the running of the conveyor belt, and the cleanliness and smoothness of the conveyor belt are maintained. The cleaning roller 71 is fixed on a transmission shaft 72, and the transmission shaft 72 is fixedly connected with the output shaft of a motor 73, so that the automatic operation of the cleaning roller 71 is realized.

[0026] Further, the base 1 is provided with support frames 74 at both ends, the second through holes 741 are arranged on the support frames 74, and the two ends of the transmission shaft 72 pass through the second through holes 741, so that the cleaning assembly 7 can be stably installed on the base 1, and the smooth operation of the transmission shaft 72 is ensured.

[0027] The working principle of the utility model is:

[0028] 1. Wood board conveying:

[0029] The wood board is placed on the second conveying belt, and the wood board is conveyed along the direction of the arrow shown in the figure to the first conveying belt, and is ready to enter the sawing area. Figure 1 The wood board is placed on the second conveying belt, and the wood board is conveyed along the direction of the arrow shown in the figure to the first conveying belt, and is ready to enter the sawing area.

[0030] 2. Wood positioning:

[0031] During the wood conveying process, the positioning roller can gently press on the wood board to prevent the wood board from tilting and ensure that the wood stably enters the sawing area. The positioning roller can also be self-adaptively adjusted according to the thickness and hardness of the wood.

[0032] 3. Sawing operation:

[0033] When the positioned wood enters the sawing area, multiple saw blades work simultaneously to efficiently and accurately saw the wood.

[0034] 4. Sweeping wood chips:

[0035] During the return process of the first conveying belt 3 and the second conveying belt 4, the motor drives the sweeping roller 71 to sweep the wood chips on the surface of the conveying belt, so that the surface of the conveying belt is kept clean when the wood board is placed again.
