Depending on the type of tree, the growth environment and the processing method, the color, texture, hardness, durability and other aspects of wood will vary. Common woods include pine, oak, walnut, birch, etc. In the production process, the wood needs to go through the processing steps of felling, peeling, drying, cutting, etc. to obtain wood that meets the requirements.

[0003] Among them, one type of wood processing requires cutting a groove on the outer wall of the log and along the axial direction of the log, and also requires cutting multiple grooves along the circumferential direction of the log to complete the processing of the log.

The regulating cylinder 12 can move the tool 11 so as to get closer to or away from the wood.

[0033] See also Figure 1 The moving seat 2 is slidably mounted on the bottom wall of the base plate 1 and slides along the length direction of the base plate 1 ; a fixed cylinder 13 is provided between the moving seat 2 and the base plate 1 , and the fixed cylinder 13 is used to push the moving seat 2 to move on the base plate 1 . A loading assembly is provided on the top wall of the bottom plate 1, and a clamping assembly 5 is provided on the top wall of the movable seat 2. During processing, the fixed cylinder 13 is first started to control the movable seat 2 to move to the loading assembly, and the loading assembly is used to transport the wood to the movable seat 2; then, the clamping assembly 5 is used to clamp the wood, and the fixed cylinder 13 is started again to move the movable seat 2 to the tool 11; then, the regulating cylinder 12 is started to control the contact between the tool 11 and the wood; finally, the fixed cylinder 13 is started again to control the movable seat 2 to move back and forth, so that the tool 11 cuts the wood to form a groove; and whenever a single groove is completed, the clamping assembly 5 can be used to rotate the wood to continue processing until all the grooves are processed. The entire operating staff does not need to reciprocate to approach or move away from the tool 11. Repeated operations not only reduce the workload, but also are not prone to errors in long-term operations, so that it is not easy to cause the staff to accidentally hurt themselves, and thus it is not easy to affect the production progress of the wood.

[0034] See also Figure 1 The feeding assembly includes: a falling part 3 and a pushing part 4.

[0035] See also Figure 1 The falling part 3 includes: a base 31, a falling plate 32 and two limiting plates 33. The base 31 is fixed on the top wall of the bottom plate 1, and the limiting plates 33 are fixed on the top wall of the base 31. The two limiting plates 33 are provided with limiting grooves 331 on opposite sides and in the vertical direction, and the wood can roll horizontally between the two limiting grooves 331. The falling plate 32 is fixed between the two limiting plates 33.

The pushing cylinder 42 is located on the side of the limiting plate 33 away from the moving seat 2. When there is no need to load materials, the pushing plate 41 is kept in the clearance groove 332 to block the wood; when loading materials is required, the pushing cylinder 42 is started to pull the pushing plate 41 back first so that a single wood can fall into the clearance groove 332; then, the pushing cylinder 42 is started again to drive the pushing plate 41 to push the wood to fall onto the moving seat 2, thereby achieving the purpose of loading materials.

[0037] See also Figure 1 The clamping assembly 5 includes: an ejector pin 51, a clamping claw cylinder 52, two rotating cylinders 53 and two telescopic cylinders 54. In the embodiment of the present application, the two rotating cylinders 53 correspond to the two telescopic cylinders 54. The telescopic cylinder 54 is fixedly mounted on the top wall of the moving seat 2, and the output shaft of the telescopic cylinder 54 is fixedly connected to the rotating cylinder 53. The telescopic cylinder 54 and the rotating cylinder 53 are both arranged horizontally. The output shaft of one rotating cylinder 53 is coaxially fixedly connected with the ejector pin 51, and the output shaft of the rotating cylinder 53 at the other end is fixedly connected with the clamping cylinder 52. In the embodiment of the present application, the clamping cylinder 52 adopts the existing four-claw cylinder. After the wood falls on the moving seat 2, the telescopic cylinder 54 is started to push the ejector pin 51 and the clamping cylinder 52 to contact the wood, so that the ejector pin 51 can support the wood, and the clamping cylinder 52 can clamp the wood, so as to stably process the wood; and each time the groove is processed, the rotating cylinder 53 is started to control the rotation of the wood, so as to facilitate the processing of the next groove. In the embodiment of the present application, a blanking plate (not shown in the figure) can also be provided to provide blanking for the processed wood.

[0038] The working principle of the first embodiment is as follows: during processing, the fixed cylinder 13 is first started to control the movable seat 2 to move to the loading assembly, and the loading assembly is used to transport the wood to the movable seat 2; then, the clamping assembly 5 is used to clamp the wood, and the fixed cylinder 13 is started again to move the movable seat 2 to the tool 11; then, the regulating cylinder 12 is started to control the contact between the tool 11 and the wood; finally, the fixed cylinder 13 is started again to control the movable seat 2 to move back and forth, so that the tool 11 cuts the wood to form a groove; and each time a single groove is completed, the clamping assembly 5 can be used to rotate the wood to continue processing until all the grooves are processed. The entire operating staff does not need to reciprocate to approach or move away from the tool 11. Repeated operations not only reduce the workload, but also make it less likely for errors to occur during long-term operation, thereby making it less likely for the staff to accidentally hurt themselves, and thus less likely to affect the production progress of the wood.

[0039] Embodiment 2: See also Figure 2 The difference between this embodiment and the first embodiment is that a coaxial component is provided between the movable seat 2 and the base plate 1. By utilizing the coaxial component, when the wood falls onto the movable seat 2, the wood can automatically remain on the coaxial line with the telescopic cylinder 54, and can ensure that the wood is located between the ejector pin 51 and the clamping claw cylinder 52, thereby facilitating the clamping of the wood and achieving an automatic clamping effect, thereby eliminating the need for manual adjustment by the operator, thereby improving processing efficiency.

[0040] See also Figure 3 , Figure 4 and Figure 5 The coaxial component includes: a driving part 7 and a coaxial part 6.

[0041] See also Figure 5 The coaxial portion 6 includes: a flush seat 61, a rising block 62 and a screw rod 63.

[0042] See also Figure 5 The inner side wall of the accommodating groove 21 is away from the base 31 and is provided with a clearance hole 22 in the vertical direction. The screw rod 63 is vertically rotated and installed in the clearance hole 22; the rising block 62 is slidably installed in the clearance hole 22 and slides in the vertical direction. The screw rod 63 penetrates the rising block 62 and cooperates with the thread of the rising block 62. When the moving seat 2 moves toward the base 31, the screw rod 63 is driven to rotate so that the rising block 62 can drive the flush seat 61 to rise; until the moving seat 2 moves to the side of the base 31, the top of the flush seat 61 is flush with the top of the base 31, so that the wood can roll smoothly onto the moving seat 2 to clamp the wood.

[0043] See also Figure 2 and Figure 5 The driving part 7 includes a driving gear 71 and a driving rack 72, and the driving rack 72 is horizontally fixed to the top wall of the bottom plate 1. The driving gear 71 is coaxially sleeved on the screw rod 63. During the movement of the moving seat 2, the driving rack 72 will mesh with the driving gear 71, so that the driving gear 71 can drive the screw rod 63 to rotate, so that the flush seat 61 can rise.

[0044] See also Figure 5 A positioning assembly is provided between the flush seat 61 and the movable seat 2, and the positioning assembly can prevent the wood from rolling excessively, thereby ensuring that after the wood falls onto the movable seat 2, the wood can be coaxial with the telescopic cylinder 54, thereby facilitating the clamping of the wood.

[0045] See also Figure 5 The positioning assembly includes: a positioning part 8, a limiting part 9 and a transmission part 10.

[0046] See also Figure 5 The positioning part 8 includes: a positioning plate 81, a positioning block 82, a threaded cylinder 83, a threaded rod 84 and a rotating cylinder 85.

During the rising process of the flush seat 61, due to the limiting of the positioning block 82, the positioning plate 81 can rise together with the flush seat 61.

[0047] See also Figure 5 The rotating cylinder 85 is rotatably installed on the bottom of the accommodating groove 21; the threaded cylinder 83 is fixed on the bottom wall of the positioning plate 81, and one end of the threaded rod 84 is threadedly connected to the threaded cylinder 83 and the other end is arranged in the rotating cylinder 85. During the rising process of the positioning plate 81, the positioning plate 81 can drive the threaded cylinder 83 and the threaded rod 84 to rise together.

A receiving hole 841 is opened at one end of the threaded rod 84 located in the rotating cylinder 85, and the limiting rod 91 is arranged in the receiving hole 841; the limiting spring 92 is fixed between the bottom of the receiving hole 841 and the limiting rod 91, and the limiting spring 92 is used to push the limiting rod 91 to extend outward.

[0049] See also Figure 5 The inner wall of the rotating cylinder 85 is provided with a limiting hole 851 for inserting the limiting rod 91. After the positioning plate 81 and the flush seat 61 are raised together, the limiting hole 851 is aligned with the accommodating hole 841, and under the push of the limiting spring 92, the limiting rod 91 is automatically inserted into the limiting hole 851 to achieve the effect of limiting the rotating cylinder 85 and the threaded rod 84. When the rotating cylinder 85 rotates, the threaded rod 84 can rotate together, thereby driving the threaded cylinder 83 to lift the positioning plate 81, so that the positioning plate 81 extends out of the through slot 611, and then the positioning plate 81 can block the wood.

[0050] See also Figure 5An inclined guide surface 911 is provided on the bottom wall of one end of the limit rod 91 away from the limit spring 92, and when the limit rod 91 is inserted into the limit hole 851, one end of the guide surface 911 close to the limit spring 92 is located outside the limit hole 851. When the positioning plate 81 needs to be lowered together with the flush seat 61, the limit rod 91 can be automatically pressed into the accommodating hole 841 through the setting of the guide surface 911, thereby not easily affecting the lowering of the threaded rod 84.

[0051] See also Figure 2 and Figure 5 The transmission part 10 includes: a transmission belt 101, a transmission rod 102, a transmission gear 103 and a transmission rack 104.

[0052] See also Figure 2 and Figure 5 The transmission belt 101 is arranged between the transmission rod 102 and the rotating cylinder 85 . When the transmission rod 102 rotates, the rotating cylinder 85 can rotate through the arrangement of the transmission belt 101 , so that the threaded cylinder 83 can lift the positioning plate 81 .

[0053] The working principle of the second embodiment is as follows: when the movable seat 2 moves toward the base 31, the screw rod 63 is driven to rotate so that the lifting block 62 can drive the flush seat 61 to rise; until the movable seat 2 moves to the side of the base 31, the top of the flush seat 61 is flush with the top of the base 31, so that the wood can be smoothly rolled onto the movable seat 2 for clamping the wood.
