DETAILED DESCRIPTION

[0023] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] See also Figure 1-Figure 4 The utility model discloses an automatic feeding device for wood production, including a machine body 10, a conveying assembly 20 and a pressing assembly 30, wherein the conveying assembly 20 and the pressing assembly 30 are both installed on the machine body 10. Specifically, the conveying assembly 20 has a conveying end surface, which can convey the wood workpiece along a conveying direction, and a plurality of gripping members are arranged on the conveying end surface.

[0027] In addition, the pressing assembly 30 includes a pressing piece and a pressing piece driving piece. The pressing piece is arranged above the conveying end surface, and the pressing piece can move close to or away from the conveying end surface. The pressing piece can apply pressure to the wood after approaching the conveying end surface so that the gripping piece extends into the wood. The above-mentioned pressing piece driving piece can drive the pressing piece to move.

[0028] On the basis of the above structure, when the automatic feeding device for wood production of the utility model is used, since logs are mainly cut during wood production, the wood in the log bin can be directly output to the conveying component 20 of the present application through a robot or a conveyor belt during production, and then received by the conveying end face of the conveying component 20 for conveying. In this way, since the surface of the wood is an arc, if there is no external force restriction, rolling, deviation, etc. are likely to occur during the conveying process.

[0029] In the present application, after the wood is received by the conveying end face of the conveying assembly 20, it can be conveyed to the bottom of the pressing piece along the conveying direction. After the wood is conveyed to the bottom of the pressing piece, the pressing piece can be driven by the pressing piece driving piece to move downward close to the conveying end face. The pressing piece can exert pressure on the wood during the downward movement. Since a number of gripping members are arranged on the conveying end face, after the wood on the conveying end face is subjected to force, the gripping members on the conveying end face can extend into the wood, so that the wood can remain relatively fixed with the conveying end face, preventing the conveying assembly 20 from slipping with the conveying end face during the process of conveying the wood, and effectively preventing the wood from deflecting, rolling, etc. during the conveying process. Therefore, the wood can maintain a stable state and enter the sawing station for sawing to complete the wood loading. In this way, the later processing process is stable, thereby improving the processing accuracy.

[0030] Of course, after the previous wood is pressed by the pressing piece and relatively fixed with the gripping piece, the conveying assembly 20 can continue to convey the wood to the next workstation. At this time, the pressing piece driving piece can drive the pressing piece to move upward and away from the conveying end surface, and the following wood can continue to be conveyed to the bottom of the pressing piece. The above-mentioned pressing piece driving piece can drive the pressing piece to move downward again, and repeat the above-mentioned pressing action. In this way, each wood conveyed by the conveying assembly 20 can be interlocked with the gripping piece on the conveying end surface, maintaining a stable conveying state for conveying and processing the wood.

[0031] Furthermore, in the present embodiment, the material pressing member comprises a swing arm 31 and a material pressing wheel 32. One end of the swing arm 31 is rotatably mounted on the machine body 10, and the other end of the swing arm 31 is provided with a material pressing wheel 32. Thus, the swing arm 31 can be driven to rotate by a material pressing member driving member. During the swinging process of the swing arm 31, the material pressing wheel 32 connected to the swing arm 31 can approach or move away from the conveying end face of the conveying assembly 20. After the material pressing wheel 32 approaches the conveying end face, it can apply pressure to the wood.

[0032] In this way, when the material pressing action is performed, the swing arm 31 can be driven to rotate downward by the material pressing member driving member. When the swing arm 31 rotates downward, the material pressing wheel 32 on the swing arm 31 can be close to the conveying end face of the conveying assembly 20. In the process of the material pressing wheel 32 approaching the conveying end face, the material pressing wheel 32 can press the wood on the conveying end face, and the material pressing wheel 32 contacts the end face of the wood with an arc surface rather than a straight line surface. In this way, during the pressing process, the wood is subjected to greater force, and it is easier to press the wood onto the gripping member of the conveying end face.

[0033] At the same time, the swing direction of the swing arm 31 can be consistent with the conveying direction, or it can swing forward from the rear of the conveying direction, which is opposite to the direction of travel of the wood. That is, when the pressure wheel swings from top to bottom, it can provide a resistance in the direction of travel of the wood, and at the same time, it can apply downward pressure from above, so that the wood and the gripping member are easier to fit together and the fitting force is stronger.

[0034] Furthermore, the pressing wheel 32 is rotatably mounted on the swing arm 31, that is, the pressing wheel 32 can rotate relative to the swing arm 31, and the pressing wheel 32 can rotate during the contact and pressing process with the wood, thereby reducing the possibility of jamming during the pressing process.

[0035] More specifically, a plurality of pressing teeth 321 may be provided on the outer peripheral wall of the pressing wheel 32, and the pressing teeth 321 are spaced apart in the circumferential direction of the pressing wheel 32. In this way, the surface friction of the pressing wheel 32 may be increased by the plurality of pressing teeth 321 on the surface of the pressing wheel 32. When the pressing wheel 32 presses the wood, the direct contact friction between the pressing wheel 32 and the wood is large, so that the sliding between the pressing wheel 32 and the wood can be reduced, thereby reducing the slipping of the wood during the pressing process.

[0036] Furthermore, the piston rod of the driving cylinder 33 can be connected to the middle end of the swing arm 31, and the top end of the swing arm 31 can be hinged on the body 10, the bottom end of the swing arm 31 is connected to the above-mentioned pressing wheel 32, and the movable rod of the driving cylinder 33 can drive the swing arm 31 to rotate during the extension and retraction process.

[0037] Compared with the motor directly driving the swing arm 31 to rotate, since the swing arm 31 needs to provide a large force during the swinging process to enable the pressing wheel 32 to press the wood after the swinging, the pressing wheel 32 and the swing arm 31 need to have a certain weight. If a motor is used, the motor will slip or the driving force will be insufficient. Therefore, in this embodiment, the piston rod of the driving cylinder 33 is used to drive, and the driving force is large and can be output smoothly. Of course, in addition to using the driving cylinder 33 to drive the swing arm 31 to rotate, it can also be driven by a driving oil cylinder, and the specific actual needs must be selected.

[0038] It should be noted that the above-mentioned pressing piece can also be used as a pendulum structure in the prior art, and the pressing action can also be achieved by driving the pendulum to swing through the pressing piece driving piece. In addition, the pressing piece can also be selected as an iron block structure in the prior art, and the pressing action can also be achieved by driving the cylinder 33 to drive the iron block structure straight up and down.

[0039] Furthermore, a centering positioning component 40 may be provided on the machine body 10. Specifically, the centering positioning component 40 is provided at the starting end of the conveying end surface, and the centering positioning component 40 and the pressing component 30 are distributed in sequence in the conveying direction.

[0040] After the wood is output from the log bin, it is received and transported by the conveying component 20. After entering the conveying end surface of the conveying component 20, it may be transported directly at the edge of the conveying end surface of the conveying component 20 or in a skewed state. If it is transported at the edge of the conveying end surface or in a skewed state, then after reaching the pressing piece, the pressing piece also presses the wood and the gripping piece at the edge position.

[0041] Therefore, before reaching the pressing assembly 30, the wood needs to be centered first. The centering positioning mechanism can guide the edge of the conveying end surface to the middle of the conveying end surface. When the wood is at the starting end of the conveying end surface, the centering alignment mechanism can be used to center the wood and guide the skewed wood to be straightened. In this way, the centered and straightened wood can continue to be transported from the conveying end surface to the bottom of the pressing piece of the pressing assembly 30 for pressing.

[0042] In this way, after the pressing piece is pressed, the wood can be located in the middle of the conveying end surface in an aligned state, and then the pressing piece is pressed downward and engaged with the gripping piece on the conveying end surface. In this way, the wood conveyed by the conveying assembly 20 can arrive at the subsequent workstation for processing in a centered and aligned state, thereby improving the processing accuracy of each subsequent process.

[0043] Furthermore, in this embodiment, the centering positioning assembly 40 includes two positioning wheel 42 mechanisms, and the two positioning wheel 42 mechanisms are respectively arranged on both sides of the starting end of the conveying end surface. Specifically, the positioning wheel 42 mechanism includes a positioning plate 41 and a positioning wheel 42, and the positioning plate 41 is installed on the machine body 10, and the positioning wheel 42 is rotatably installed on the positioning plate 41.

[0044] Based on this structure, when centering the wood, the wood received by the conveying assembly 20 can reach between the two positioning plates 41, and the wood can be guided in by the positioning wheels 42 on both sides, and centered under the action of the positioning wheels 42 on both sides, thereby achieving centering.

[0045] In addition, the positioning wheel 42 is used to center the wood, and the positioning wheel 42 can cooperate with the surface of the wood in rolling, and can also guide the smooth transportation of the wood. The wood can also be transported during the positioning process, thereby reducing the possibility of jamming.

[0046] Furthermore, the above-mentioned centering alignment mechanism also includes a positioning drive 43, which can drive the two positioning plates 41 to move closer to or away from each other. In this way, the interval between the two positioning plates 41 can be adjusted by the positioning drive 43, and the wood is transported and positioned by the positioning interval formed by the positioning wheels 42 on the two positioning plates 41, and the outer diameter of the transported wood varies. Therefore, by setting the positioning drive 43, when the outer diameter of the wood is large, the two positioning plates 41 can be driven away from each other by the positioning drive 43, so that the positioning interval formed by the positioning wheels 42 of the two positioning plates 41 is relatively large, which is suitable for positioning and centering wood with a larger outer diameter. When the outer diameter of the wood is small, the two positioning plates 41 can be driven closer to each other by the positioning drive 43, so that the positioning interval formed by the positioning wheels 42 of the two positioning plates 41 is relatively small, which is suitable for positioning and centering wood with a smaller outer diameter.

[0047] That is, in the present application, a positioning drive 43 is provided to drive the two positioning plates 41 to move closer to or farther from each other, so as to adjust the size of the positioning interval between the positioning wheels 42 on both sides, which is suitable for centering and positioning transportation of wood with different outer diameters.

[0048] It should be noted that the positioning drive member can be implemented by a linear motion drive structure such as a cylinder or an oil cylinder in the prior art, and the selection is made according to actual needs.

[0049] More specifically, positioning wheels 42 are provided at both ends of the positioning plate 41 in the conveying direction, so that when the wood is conveyed on the conveying end surface of the conveying assembly 20, the wood can be guided into the positioning interval by the positioning wheel 42 located at the front end in the conveying direction. Under the conveying force of the conveying end surface, the wood is conveyed in the positioning interval, and then guided out by the positioning wheel 42 located at the rear end in the conveying direction. The positioning wheels 42 are provided in front and behind the wood in the conveying direction for centering, and then the wood enters under the pressing piece for clamping, so that the wood can reach under the pressing piece immediately after centering for clamping to prevent rolling.

[0050] Of course, the centering positioning structure can also adopt a positioning block structure, and a cylinder piston or a push rod structure is used to push the positioning block close to the wood, and the skewed wood is pushed to the middle position for correction, so as to achieve the above-mentioned centering positioning action, except that the positioning wheels 42 on both sides of the present application are used for rolling guidance, and the centering positioning is completed during the transportation process, which does not affect the normal transportation and is more efficient.

[0051] In addition, it should be noted that a plurality of positioning wheels 42 stacked in the height direction can be provided at both ends of the positioning plate 41 and arranged according to the height of the wood, so that the centering positioning effect is better.

[0052] Furthermore, the conveying assembly 20 in this embodiment includes a conveying chain 21, a sprocket 22 and a sprocket 22 driving member. The conveying chain 21 is wound around the sprocket 22. Specifically, sprockets 22 are arranged on both sides of the body 10, and the two ends of the conveying chain 21 can be wound around the sprockets 22 at both ends. In this way, the horizontal transmission section of the conveying chain 21 between the two sprockets 22 can be formed as a conveying end face. When conveying, the sprocket 22 can be driven to rotate by a motor, and the rotation of the sprocket 22 can drive the conveying chain 21 to transmit, and the wood can be conveyed on the conveying end face formed by the conveying chain 21.

[0053] It should be noted that a plurality of sharp teeth 23 may be provided on the conveying chain 21, and the plurality of sharp teeth 23 may be spaced apart in the length direction of the conveying chain 21, so that after the wood is placed on the conveying chain 21, the sharp teeth 23 may be located below the wood, and when the wood is conveyed to below the pressing piece, the pressing piece moves downward to apply pressure on the wood, so that the wood can be pressed against the sharp teeth 23, and the sharp teeth 23 may be embedded in the wood, so that the wood can be fixed relative to the conveying chain 21, and on the basis of this structure, the sharp teeth 23 are formed into the above-mentioned gripping piece.

[0054] Of course, the conveying assembly 20 can be a conveying belt, on which a blade structure can be provided, and the blade can be inserted into the wood under the action of a material pressing member, or a pin structure can be provided to penetrate into the wood at the same time, both of which can form the gripping member structure.

[0055] Furthermore, a baffle 11 can be provided on the machine body 10, and a baffle 11 structure can be provided on both sides of the conveying end surface of the conveying assembly 20. The baffles 11 on both sides can prevent the wood from entering the conveying end surface of the conveying assembly 20 and then rolling away from the conveying assembly 20, thereby preventing the wood from falling from both sides, and making the conveying and feeding structure more stable.

[0056] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
