Description

Technical Field

[0001] This utility model relates to a feeding device for cross-cutting wood, belonging to the field of woodworking machinery technology. Background Technology

[0002] A wood cross-cutting saw is a device that cuts boards into predetermined lengths. Woodworking machinery refers to a type of machine tool used in wood processing to process semi-finished wood products into wood products. Among woodworking machinery, sawing is the most commonly used processing method. For example, a wood cross-cutting saw is a device that cuts wood into predetermined lengths.

[0003] The prior art, patent application number 202220332780X, discloses an automatic wood cross-cutting saw, including a frame 1 and a feeding mechanism 3 and a slitting mechanism 7 mounted on the frame 1. This prior art has a drawback: due to insufficient frame length, the slitting mechanism 7 can only accommodate one or two rows of saw blades, making it impossible to cross-cut the wood into shorter pieces. Therefore, when it is necessary to cross-cut the wood into shorter pieces, the frame length must be increased to accommodate multiple rows of saw blades. This results in an excessively long chain in the feeding mechanism 3, which is prone to loosening or skipping teeth during operation, affecting feeding stability and cutting accuracy. Furthermore, an excessively long chain increases wear, reduces transmission efficiency, and increases maintenance costs.

[0004] Moreover, the feeding mechanism 3 of the prior art also has a defect. When it is necessary to cut the wood into shorter pieces, the levers on the lever frame are densely distributed. Before the wood is sent to the cutting mechanism 7, it needs to be moved left and right for adjustment. When the wood ends move left and right, they are prone to slight deviation and collision with the two outermost sets of levers, resulting in jamming and affecting the normal operation of the feeding process.

[0005] Therefore, the research objective of this utility model is to provide a feeding device for cross-cutting wood that provides stable feeding and avoids jamming. Utility Model Content

[0006] To address the shortcomings of the aforementioned technologies, this utility model provides a feeding device for cross-cutting wood. The device adopts a three-section feeding structure, wherein the chains of the first feeding mechanism and the second feeding mechanism are set independently to avoid the problem of unstable feeding caused by excessively long chains. Furthermore, the levers arranged on the first feeding mechanism are relatively central and sparsely distributed, preventing the wood end from colliding with the two outermost sets of levers when moving left and right, thus avoiding the problem of jamming.

[0007] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows: A timber cross-cutting feeding device includes a frame and a first feeding mechanism and a second feeding mechanism mounted on the frame, as well as a third feeding mechanism for pushing timber from the first feeding mechanism to the second feeding mechanism. The first feeding mechanism includes several sets of first material support rods disposed on the top of the frame, and a first chain arranged in a ring below the first material support rods. Several sets of first lever frames are spaced apart along the circumference of the first chain. Several sets of first levers are spaced apart on the first lever frames. The first levers pass through the space between two sets of first material support rods and extend above the first material support rods. The second feeding mechanism includes several sets of second material support rods located on the top of the frame, and a second chain arranged in a ring below the second material support rods. Several sets of second lever frames are spaced apart along the circumference of the second chain. Several sets of second levers are spaced apart on the second lever frames. The second levers pass through the space between two sets of second material support rods and extend above the second material support rods. The third feeding mechanism includes two sets of vertical plates arranged across the width of the frame. A third chain is arranged in a ring on the inner side of the vertical plates. Several sets of third lever frames are arranged at intervals along the circumference of the third chain. Several sets of third levers are arranged at intervals on the third lever frames.

[0008] Furthermore, the end of the first feeding mechanism away from the second feeding mechanism is the infeed end, and the end of the second feeding mechanism away from the first feeding mechanism is the discharge end.

[0009] Furthermore, one end of the first chain is connected to a first reducer via a first transmission rod, and one end of the second chain is connected to a second reducer via a second transmission rod. The first reducer and the second reducer are synchronously driven by a linkage rod, and a servo motor is driven to the input end of the second reducer.

[0010] Furthermore, a third transmission rod is rotatably provided at one end of the third chain, and the third transmission rod is synchronously driven with the first transmission rod through a chain sprocket.

[0011] Furthermore, several groups of second levers are evenly distributed along the width direction of the frame, and several groups of first levers are centrally distributed along the width direction of the frame, with the interval between two adjacent groups of first levers being greater than the interval between two adjacent groups of second levers.

[0012] Furthermore, the first and second material support rods are connected end to end and are arranged along the length of the frame.

[0013] Furthermore, a reference plate is fixedly provided on one side of the top of the frame, and the reference plate extends from the first feeding mechanism to the second feeding mechanism.

[0014] The beneficial effects of this utility model are: 1. The whole adopts a three-section feeding structure, in which the chains of the first feeding mechanism and the second feeding mechanism are set independently, avoiding the problem of unstable feeding caused by excessively long chains; 2. The levers arranged on the first feeding mechanism are relatively central and sparsely distributed, avoiding the problem of material jamming caused by the wood end colliding with the two outermost levers when it moves left and right.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-8 Further analysis of this utility model is then conducted.

[0025] like Figure 1-8As shown, a timber cross-cutting feeding device includes a frame 10 and a first feeding mechanism 20 and a second feeding mechanism 30 disposed on the frame 10, as well as a third feeding mechanism 40 for pushing timber from the first feeding mechanism 20 to the second feeding mechanism 30. The first feeding mechanism 20 includes several sets of first material support rods 201 disposed on the top of the frame 10, and a first chain 202 arranged in a ring below the first material support rods 201. Several sets of first lever frames 203 are spaced apart along the circumference of the first chain 202. Several sets of first levers 204 are spaced apart on the first lever frames 203. The first levers 204 pass through the space between two sets of first material support rods 201 and extend above the first material support rods 201. The second feeding mechanism 30 includes several sets of second material support rods 301 disposed on the top of the frame 10, and a second chain 302 arranged in a ring below the second material support rods 301. Several sets of second lever frames 303 are spaced apart along the circumference of the second chain 302. Several sets of second levers 304 are spaced apart on the second lever frames 303. The second levers 304 pass through the space between two sets of second material support rods 301 and extend above the second material support rods 301. The third feeding mechanism 40 includes two sets of vertical plates 401 arranged across the width of the frame 10. A third chain 402 is arranged in a ring on the inner side of the vertical plate 401. Several sets of third lever frames 403 are arranged at intervals along the circumference of the third chain 402. Several sets of third levers 404 are arranged at intervals on the third lever frames 403.

[0026] In this embodiment, preferably, the end of the first feeding mechanism 20 away from the second feeding mechanism 30 is the feeding end, and the end of the second feeding mechanism 30 away from the first feeding mechanism 20 is the discharging end.

[0027] In this embodiment, preferably, one end of the first chain 202 is connected to a first reducer 206 via a first transmission rod 205, and one end of the second chain 302 is connected to a second reducer 306 via a second transmission rod 305. The first reducer 206 and the second reducer 306 are synchronously driven by a linkage rod 50, and a servo motor 60 is driven to the input end of the second reducer 306.

[0028] In this embodiment, preferably, a third transmission rod 405 is rotatably provided at one end of the third chain 402. The third transmission rod 405 is synchronously driven with the first transmission rod 205 through a chain sprocket. A set of servo motors 60 synchronously drives the first transmission rod 205, the second transmission rod 305 and the third transmission rod 405 to operate synchronously, which effectively ensures the synchronization of the feeding speed of the first feeding mechanism 20, the second feeding mechanism 30 and the third feeding mechanism 40, and makes the feeding more stable.

[0029] In this embodiment, preferably, several groups of second levers 304 are evenly distributed along the width direction of the frame 10, and several groups of first levers 204 are centrally distributed along the width direction of the frame 10. The interval between two adjacent groups of first levers 204 is greater than the interval between two adjacent groups of second levers 304, so as to avoid the problem of material jamming when the end of the wood moves left and right and collides with the two outermost groups of levers.

[0030] In this embodiment, preferably, the first material support rod 201 and the second material support rod 301 are connected end to end and arranged along the length direction of the frame 10. The wood is placed on the first material support rod 201 and the second material support rod 301 and is pushed by the first lever 204 and the second lever 304 to be fed towards the discharge end.

[0031] In this embodiment, preferably, a reference plate 101 is also fixed on one side of the top of the frame 10. The reference plate 101 extends from the first feeding mechanism 20 to the second feeding mechanism 30. During the feeding process, the wood is driven by the positioning roller mechanism on the cross-cutting saw to move towards the reference plate 101. This allows one end of the wood to be neatly cut, which is beneficial for accurate cutting.

[0032] The specific working principle of this utility model is as follows: Long rod-shaped wood is fed from the feed end into the first support rod 201 of the first feeding mechanism 20, and is pushed by the first lever 204 towards the second feeding mechanism 30. When the wood is conveyed to the end of the first feeding mechanism 20 close to the second feeding mechanism 30, the third lever 404 of the third feeding mechanism 40 pushes the wood from the first feeding mechanism 20 to the second feeding mechanism 30. After the wood enters the second feeding mechanism 30, the second feeding mechanism 30 cooperates with the pressing mechanism on the cross-cutting saw to press the wood and convey it to the slitting mechanism. The slitting mechanism cuts the wood into short pieces, and then the second lever 304 of the second feeding mechanism 30 continues to push the wood to the discharge end for discharge.

[0033] This utility model adopts a three-section feeding structure. The chains of the first feeding mechanism 20 and the second feeding mechanism 30 are set independently, which avoids the problem of unstable feeding caused by excessively long chains and is more suitable for cutting shorter wood. In addition, the levers arranged on the first feeding mechanism 20 are relatively central and sparsely distributed, which avoids the problem of wood end colliding with the two outermost levers when moving left and right, thus avoiding the problem of jamming.
