[0057] In the embodiments of the present application, the wood conveyor uses the first chain 310 and the second chain 410 to generate conveying power on both sides of the wood; in addition, both the first chain 310 and the second chain 410 form multi-point contact or line contact extending along the first direction X with both sides of the wood, which is beneficial to realizing the stable conveying of the wood for splicing, reducing the misalignment of the wood teeth during the feeding process, and thus being beneficial to reducing the generation of defective products during subsequent wood splicing and improving the quality of subsequent wood splicing. In addition, the interval distance between the second chain 410 and the first chain 310 is adjustable, so that the width of the conveying channel can be adjusted to flexibly adapt to the conveyance of wood with different width dimensions, and the versatility is stronger.

[0058] In some embodiments, reference Figure 2-3 , the first sprocket chain mechanism 300 further includes a first driving source, a first driving wheel 330, and a first driven wheel 340. The first driving source is arranged on the frame 100; the first driving wheel 330 is coaxially connected to the output end of the first driving source; the first driven wheel 340 is arranged on the frame 100, and the first chain 310 is sleeved on the first driving wheel 330 and the first driven wheel 340 for transmission drive to convey the wood.

[0059] In some embodiments, referring to Figure 2-3 , the first chain 310 includes a first power chain segment facing the conveying channel, and the first sprocket chain mechanism 300 further includes a supporting backing plate 350. The supporting backing plate 350 is arranged on the frame 100 and extends along the first direction X. The supporting backing plate 350 is tightly attached to the side of the first power chain segment facing away from the conveying channel for supporting the first power chain segment. The supporting backing plate 350 plays a role in supporting and shaping the first power chain segment, enabling the first power chain segment to maintain an extension along the first direction X, and realizing the stable guiding and conveying of the wood being conveyed along the first direction X.

[0060] In some embodiments, referring to Figure 2-3 , the supporting backing plate 350 includes a wear-resistant part and a supporting main body part. The wear-resistant part is in direct supporting contact with the first power chain segment, and the material of the wear-resistant part is a wear-resistant material to improve the service life.

The wear-resistant material can be wear-resistant ceramics, metals, plastics, etc.

[0061] Referring to Figure 2-3 , in some embodiments, one end of the conveying channel is a feeding port, and the other end of the conveying channel is a discharging port; wherein, the first driving wheel 330 is located on the side close to the discharging port, and the first driven wheel 340 is located on the side close to the feeding port. Further, the first power chain segment can be further tensioned, so that the first power chain segment is in a tensioned state and is pressed against the supporting backing plate 350.

In this way, the second power chain segment of the second chain 410 facing the conveying channel will have a certain degree of slack, which is convenient for the wood in the conveying process to fit and deform.

[0065] Furthermore, in some embodiments, referring to Figure 2-3 , the second chain 410 includes a second power chain segment facing the conveying channel, and the second sprocket chain mechanism 400 further includes a side pressing spring wheel component 450. The side pressing spring wheel component 450 is disposed on the linkage mechanism 500, and the side pressing spring wheel component 450 elastically presses against one side of the second power chain segment facing away from the conveying channel to elastically tension the second power chain segment, so that the second power chain segment has an elastic slack characteristic, and then fits against the side of the wood to provide conveying power. The second driving wheel 430 is located on the side close to the feeding port, and together with the side pressing spring wheel component 450, a reverse pulling type conveying structure is formed, and the second power chain segment has an elastic slack characteristic.

The second tensioning member 460 may be an existing compression spring type elastic tensioning device, etc., and is not specifically limited, as long as its corresponding tensioning function is achieved.

[0068] In some embodiments, referring to Figure 2-3 , the linkage mechanism 500 includes a displacement frame 510 and a displacement driving source 520. The displacement frame 510 is disposed on the frame 100 so as to be movable back and forth along the second direction Y. The second sprocket chain mechanism 400 is disposed on the displacement frame 510; the displacement driving source 520 is disposed on the frame 100 and is drivingly connected to the displacement frame 510 to move the displacement frame 510 along the second direction Y, thereby realizing the position adjustment of the second sprocket chain mechanism 400 along the second direction Y, so as to adjust the distance between the second chain 410 and the first chain 310, and to adjust the width of the conveying channel. The second direction Y is perpendicular to the first direction X. The displacement frame 510 can be installed on the frame 100 through a linear slide rail and slider extending along the second direction Y, which will not be elaborated here. The displacement driving source 520 can be a linear cylinder to push and pull the displacement frame 510 to move back and forth along the second direction Y; it can also be an existing rotating motor cooperating with a pull rod to form the displacement driving source 520 to push and pull the displacement frame 510 to move back and forth along the second direction Y. As long as it is an existing one that can drive the displacement frame 510 to move back and forth along the second direction Y, it is not specifically limited.

[0069] For explanatory purposes, the first driving source, the second driving source, and the wear-resistant part of the supporting plate; the supporting main body part of the supporting plate are not shown or marked in the figure.

[0070] Finally, it should be noted that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered as the scope described in this specification.
