Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically a stepped wood-loading machine. Background Technology

[0002] In the wood processing process, wood needs to be lifted and loaded so that wood on the ground or at a lower level can be transferred to a higher conveyor belt or other structure for further processing. A ladder wood lifting machine is one of the devices used to lift wood. Traditional ladder wood lifting machines use a single ladder. After lifting the wood to a certain height, the wood needs to be stopped on the bearing surface until the lifting ladder pushes out again to complete the loading of the wood in one go.

[0003] In the above process, due to the use of a single-step structure, the wood moves one step at a time. The long single displacement distance of the wood can easily lead to poor stability during the loading process. In addition, the wood needs to be repeatedly placed on a fixed step until the moving step structure pushes the wood out again. The dwell time prevents the loading speed from being increased. Utility Model Content

[0004] The purpose of this utility model is to provide a ladder-mounted wood loading machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stepped wood-loading machine, comprising fixed side plates, two sets of fixed side plates symmetrically arranged, with a first wood-loading step and a second wood-loading step alternately arranged between the two sets of fixed side plates, the back of the first wood-loading step and the back of the second wood-loading step slidingly limited to the two sets of fixed side plates, a synchronous interleaved reciprocating drive assembly arranged between the two sets of fixed side plates and between the first wood-loading step and the second wood-loading step, the synchronous interleaved reciprocating drive assembly being used to control the first wood-loading step and the second wood-loading step to move synchronously and interleavedly up and down between the two sets of fixed side plates.

[0006] The present invention is further configured such that the synchronous interleaved reciprocating drive assembly includes a rotating shaft, the rotating shaft is mounted between two sets of fixed side plates via bearings, a drive motor is provided between the two sets of fixed side plates, a reducer is provided at the output end of the drive motor, a reciprocating rotation control structure is provided between the reducer and the rotating shaft, and a synchronous interleaved reciprocating control structure is provided between the rotating shaft and the first upper wooden step and the second upper wooden step.

[0007] The present invention is further configured such that the reciprocating rotation control structure includes a connecting frame, the reducer is provided with multiple output shafts, the connecting frame is eccentrically positioned at the output end corresponding to the output shaft, and a main drive rod is hinged to the tail end of the connecting frame. The main drive rod is hinged to the rotating shaft, and the reciprocating pull of the main drive rod is controlled by the rotation of the output shaft, thereby realizing the reciprocating rotation drive of the rotating shaft, so that the rotating shaft can realize reciprocating rotation.

[0008] The present invention is further configured such that: a first mounting shaft is provided at the top back of the first upper wooden step, and a second mounting shaft is provided at the top back of the second upper wooden step; the first and second mounting shafts are staggered; a first guide wheel is provided at the outer end of both the first and second mounting shafts; a first slide rail is provided on the fixed side plate, and a first sliding groove is provided on the first slide rail; two sets of first guide wheels on the same side are rolled in the first sliding groove in a staggered manner; a third mounting shaft is provided at the bottom back of the first upper wooden step, and a fourth mounting shaft is provided at the bottom back of the second upper wooden step; a second guide wheel is provided at the outer end of both the third and fourth mounting shafts; a second slide rail is provided on the fixed side plate, and a second sliding groove is provided on the second slide rail; two sets of second guide wheels on the same side are rolled in the second sliding groove in a staggered manner. Through the cooperation of the first and third mounting shafts with the corresponding first and second guide wheels, the first upper wooden step can move along the first and second sliding grooves on the fixed side plate, improving the stability of the first upper wooden step during operation; the principle of the second upper wooden step is the same.

[0009] The present invention is further configured such that the synchronous interlaced reciprocating control structure includes a drive frame, the drive frame is fixed on a rotating shaft, one end of the drive frame is hinged to a first pull rod, and the other end is hinged to a second pull rod, the tail end of the first pull rod is hinged to a first mounting shaft, and the tail end of the second pull rod is hinged to a fourth mounting shaft, thereby realizing the synchronous interlaced reciprocating movement of the first and second wooden steps.

[0010] The present invention is further configured such that both the first and second upper wooden steps include multiple upper wooden steps, and a protective liner is detachably provided on the surface of each upper wooden step. Each upper wooden step includes a bearing surface and a limiting surface. A limiting groove is provided on the limiting surface, and a limiting strip is provided on the protective liner to cooperate with the limiting groove. A fixing bolt is provided between the protective liner and the bearing surface. The protective liner can improve the wear resistance of the surface of the upper wooden steps in the first and second upper wooden steps, reduce the wear of the first and second upper wooden steps, and facilitate easy replacement after wear. During installation, the protective liner is first slidably installed on the corresponding upper wooden step through the cooperation of the limiting strip and the limiting groove, and then the fixing bolt is used to lock and fix the protective liner to the bearing surface. This can improve the installation stability and disassembly convenience of the protective liner.

[0011] The present invention is further configured such that a support frame is provided in front of the fixed side plate, a rotating roller is provided on the support frame via a bearing, a flipping frame is provided on the rotating roller, one end of the rotating roller extends to the outside of the support frame and is connected to a driving structure.

[0012] The present invention is further configured such that the driving structure includes a driving shaft, the driving shaft is disposed at the output end of the output shaft, and a synchronous belt drive structure is disposed between the extension end of the rotating roller and the driving shaft.

[0013] The present invention is further configured such that the driving structure is a control motor, and the control motor is connected to the rotating roller. The rotation of the rotating roller can control the rotation of the tilting frame, thereby realizing the transfer of wood when it is loaded onto the step woodworking machine. In this way, the wood can be prevented from directly impacting the step woodworking machine when it rolls down, thus improving the operating efficiency of the step woodworking machine.

[0014] The present invention is further configured such that a guide frame is provided in front of the support frame, and a lifting groove is provided on the guide frame in conjunction with the tilting frame. An installation groove is provided in front of the guide frame, and a baffle is hinged to the top of the installation groove. A gas spring rod is hinged between the baffle and the inner wall of the installation groove. When the wood rolls from the guide frame to the rotating roller, it will rush towards the baffle and push the baffle to move under the impact force. At the same time, the baffle can block the rolling wood and reduce the forward impact of the wood. During this process, the gas spring rod is compressed until the baffle is stored in the installation groove or slightly flipped up. The wood is stably located at the top of the lifting groove, so that the tilting frame can directly lift the wood and drive it to tilt during rotation. In this way, the wood can be transported to the first and second wood-loading steps that move up and down during the tilting process, thereby realizing wood loading and reducing the impact of wood rolling directly down the guide frame on the wood-loading machine, reducing the damage and impact caused by wood impact.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Improve feeding efficiency and stability

[0017] This invention utilizes a synchronous, alternating reciprocating drive assembly to achieve synchronous, alternating up-and-down reciprocating movement of the first and second timber-loading steps. The drive motor, through a reducer, connecting frame, main drive rod, and rotating shaft, controls the alternating movement of the first and second timber-loading steps, enabling the timber to be continuously and smoothly lifted step by step during loading. Compared to traditional single-step structures, this design shortens the displacement distance of each timber loading operation and reduces dwell time, thus significantly improving loading efficiency. Simultaneously, the alternating movement of the steps reduces impact and shaking of the timber during transport, enhancing loading stability and preventing deviation or slippage caused by long-distance single movements.

[0018] 2. Reduce equipment wear and maintenance costs

[0019] This invention features removable protective lining plates on the surface of both the first and second wooden steps, allowing for quick installation and replacement via limiting grooves and fixing bolts. The protective lining plates effectively resist wear caused by wood friction and impact, extending the service life of the steps. When a lining plate is damaged, it can be replaced simply by removing the fixing bolts, eliminating the need for complete disassembly and repair of both the first and second wooden steps, significantly reducing maintenance costs and time. Furthermore, the coordinated design of the guide wheels and slide rails further reduces frictional resistance during step movement, ensuring smooth operation while reducing the load on the drive components and improving the overall durability of the equipment.

[0020] 3. Optimize the feeding process and reduce impact damage.

[0021] This invention adds a guide frame and a tilting frame structure to the front of the stepped wood-loading machine. Through the buffering effect of baffles and gas spring rods, the impact force when wood rolls down is effectively reduced. After the wood slides onto the lifting groove above the guide frame, the tilting frame smoothly lifts it and transfers it to the loading position of the first and second wood-loading steps, avoiding damage caused by direct impact of the wood onto the first and second wood-loading steps. This design not only protects the equipment but also makes the loading process more controllable. Furthermore, the tilting frame can be driven by a synchronous belt drive linked to the main drive motor, achieving synchronized operation, further simplifying the structure and reducing energy consumption, reflecting a high-efficiency and energy-saving design concept.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides a technical solution: Please refer to Figures 1-8A stepped wood-loading machine includes fixed side plates 1, with two sets of fixed side plates 1 symmetrically arranged. A first wood-loading step 2 and a second wood-loading step 3 are arranged alternately between the two sets of fixed side plates 1. The back of the first wood-loading step 2 and the back of the second wood-loading step 3 are slidably limited to the two sets of fixed side plates 1. A synchronous interleaved reciprocating drive assembly is arranged between the two sets of fixed side plates 1 and between the first wood-loading step 2 and the second wood-loading step 3. The synchronous interleaved reciprocating drive assembly is used to control the first wood-loading step 2 and the second wood-loading step 3 to move synchronously and interleaved up and down between the two sets of fixed side plates 1.

[0030] Please see Figures 1-8 As one implementation of the synchronous interleaved reciprocating drive assembly: the synchronous interleaved reciprocating drive assembly includes a rotating shaft 4, which is mounted between two sets of fixed side plates 1 via bearings.

[0031] Please see Figures 1-8 As one implementation of the reciprocating rotation control structure: The reciprocating rotation control structure includes a connecting frame 7, a reducer 6 is provided with multiple output shafts 8, the connecting frame 7 is eccentrically set at the output end of the corresponding output shaft 8, and the tail end of the connecting frame 7 is hinged with a main drive rod 9, which is hinged to the rotating shaft 4. The rotation of the output shaft 8 controls the reciprocating pull of the main drive rod 9, thereby realizing the reciprocating rotation drive of the rotating shaft 4, so that the rotating shaft 4 can realize reciprocating rotation.

[0032] This utility model has a first mounting shaft 10 at the top back of the first upper wooden step 2 and a second mounting shaft 11 at the top back of the second upper wooden step 3. The first mounting shaft 10 and the second mounting shaft 11 are staggered. A first guide wheel 12 is provided at the outer end of both the first mounting shaft 10 and the second mounting shaft 11. A first slide rail 13 is provided on the fixed side plate 1, and a first sliding groove 14 is formed on the first slide rail 13. Two sets of first guide wheels 12 on the same side are rolled in the first sliding groove 14 in a staggered manner. A third mounting shaft 15 is provided at the bottom back of the first upper wooden step 2, and a fourth mounting shaft 15 is provided at the bottom back of the second upper wooden step 3. The outer ends of the mounting shaft 16, the third mounting shaft 15, and the fourth mounting shaft 16 are all provided with second guide wheels 17. The fixed side plate 1 is provided with a second slide rail 18, and the second slide rail 18 is provided with a second sliding groove 19. The two sets of second guide wheels 17 on the same side are rolled in the second sliding groove 19 in a staggered manner. Through the cooperation of the first mounting shaft 10, the third mounting shaft 15 and the corresponding first guide wheel 12 and second guide wheel 17, the first upper wooden step 2 can move along the first sliding groove 14 and the second sliding groove 19 on the fixed side plate 1, thereby improving the stability of the first upper wooden step 2 during operation. The second upper wooden step 3 operates on the same principle.

[0033] In this utility model, the synchronous interlaced reciprocating control structure includes a drive frame 20, which is fixed on the rotating shaft 4. One end of the drive frame 20 is hinged to a first pull rod 21, and the other end is hinged to a second pull rod 22. The tail end of the first pull rod 21 is hinged to a first mounting shaft 10, and the tail end of the second pull rod 22 is hinged to a fourth mounting shaft 16, thereby realizing the synchronous interlaced reciprocating movement of the first upper wooden step 2 and the second upper wooden step 3.

[0034] Please see Figures 1-8 As one embodiment of the first upper wooden step 2 and the second upper wooden step 3: both the first upper wooden step 2 and the second upper wooden step 3 include multiple upper wooden steps 23. Each upper wooden step has a removable protective liner 24 on its surface. Each upper wooden step includes a bearing surface 25 and a limiting surface 26. A limiting groove 27 is formed on the limiting surface 26. A limiting strip 28 is provided on the protective liner 24 to cooperate with the limiting groove 27. A fixing bolt 29 is provided between the protective liner 24 and the bearing surface 25. The protective liner 24 can improve the height of the first upper wooden step. The wear-resistant protection of the upper wooden steps of the first upper wooden step 2 and the second upper wooden step 3 reduces the wear of the first upper wooden step 2 and the second upper wooden step 3. At the same time, it can be easily replaced after wear. During installation, the protective liner 24 is first slidably installed on the corresponding first upper wooden step 2 or second upper wooden step 3 through the cooperation of the limiting slide strip 28 and the limiting slide groove 27. Then, the protective liner 24 is locked and fixed to the bearing surface 25 by the fixing bolt 29. This can improve the installation stability and disassembly convenience of the protective liner 24.

[0035] This utility model has a support frame 30 provided in front of the fixed side plate 1. A rotating roller 31 is mounted on the support frame 30 via bearings. A tilting frame 32 is mounted on the rotating roller 31. One end of the rotating roller 31 extends to the outside of the support frame 30 and is connected to a drive structure for transmission.

[0036] The drive structure includes a drive shaft 33, which is located at the output end of a set of output shafts 8. A synchronous belt drive structure 34 is provided between the extension end of the rotating roller 31 and the drive shaft 33. Here, the transmission ratio of the synchronous belt drive structure 34 is controlled so that when the first upper wooden step 2 and the second upper wooden step 3 achieve one reciprocating motion, the flipping frame 32 rotates one set. Thus, during the reciprocating motion of the first upper wooden step 2 and the second upper wooden step 3 controlled by the drive motor 5, the flipping of the flipping frame 32 can be controlled synchronously. This ensures that the flipping frequency of the flipping frame 32 matches the feeding frequency of the first upper wooden step 2 and the second upper wooden step 3. As a result, the synchronous drive of multiple sets of structures is achieved through a set of drive motors 5, reducing equipment costs.

[0037] The drive structure is a control motor, which is connected to the rotating roller 31. In this way, although a single control motor is used, the rotating roller 31 can be controlled independently, improving the flexibility of operation.

[0038] The rotation of the rotating roller 31 can control the rotation of the tilting frame 32, thereby realizing the transfer of wood when it is loaded onto the step woodworking machine. This can avoid the situation where the wood directly impacts the step woodworking machine when it rolls down, improve the operation efficiency of the step woodworking machine, and improve the controllability of the loading.

[0039] Please see Figures 1-8As one embodiment of the support frame 30: a guide frame 35 is provided in front of the support frame 30. A lifting groove 36 is provided on the guide frame 35 in conjunction with the tilting frame 32. An installation groove 37 is provided in front of the guide frame 35. A baffle 38 is hinged to the top of the installation groove 37. A gas spring rod 39 is hinged between the baffle 38 and the inner wall of the installation groove 37. When the wood rolls from the guide frame 35 towards the rotating roller 31, it will impact the baffle 38 and, under the impact force, push the baffle 38 to move. Simultaneously, the baffle 38 can shield the rolling wood, reducing the forward impact of the wood. During this process... The gas spring rod 39 is compressed until the baffle 38 is retracted into the mounting slot 37 or slightly flipped up. The wood is stably located at the top of the lifting slot 36, so that the tilting frame 32 can directly lift the wood and drive it to tilt during rotation. In this way, the wood can be transported to the first and second wood-loading steps 2 and 3 that move up and down in a reciprocating manner during the tilting process, thereby reducing the impact of the wood rolling directly down the guide frame 35 on the wood-loading machine and reducing the damage and impact caused by the wood impact. Here, the parameter selection of the gas spring rod 39 can be determined according to the specifications of the wood being transported.

[0040] In summary, the working principle and specific workflow of this utility model are as follows:

[0041] In use, the present invention provides driving force through the drive motor 5, and outputs it after being reversed by the reducer 6. When the output shaft 8 rotates, it will drive the connecting frame 7 to rotate. The reciprocating rotation of the rotating shaft 4 can be controlled by the cooperation between the connecting frame 7 and the main drive rod 9.

[0042] Here, the output shaft 8, corresponding to the connecting frame 7, is symmetrically arranged on both sides of the reducer 6;

[0043] When the rotating shaft 4 reciprocates, it controls the drive frame 20 to reciprocate. As the drive frame 20 reciprocates, it is pulled back and forth by the first pull rod 21 and the second pull rod 22. Since the first pull rod 21 and the second pull rod 22 are respectively hinged at both ends of the drive frame 20 and are in opposite directions, when the drive frame 20 rotates, it can pull the first mounting shaft 10 downward with the cooperation of the first pull rod 21. This allows the first mounting shaft 10 to drive the first upper wooden step 2 to move downward. At the same time, the second pull rod 22 can control the fourth mounting shaft 16 to move upward, thereby controlling the second upper wooden step 3 to move upward. This achieves synchronous up-and-down misalignment control of the first upper wooden step 2.

[0044] When the rotating shaft 4 rotates, it controls the first upper wooden step 2 to move down, while the second upper wooden step 3 moves up simultaneously. This cycle repeats, allowing the first upper wooden step 2 and the second upper wooden step 3 to alternate sequentially when loading wood, thereby shortening the distance of each loading, improving the smoothness and stability of loading, reducing the dwell time of the wood in the existing single-step driven upper wooden structure, and improving the wood processing efficiency and loading stability.

[0045] Meanwhile, in the existing technology, two sets of inclined rollers are set in front of the step-mounted log machine to guide the lower logs towards the step-mounted log machine during the step-mounted log process. However, in this case, the logs will roll to the bottom of the step-mounted log machine and hit the step-mounted log machine under the impact force. In the process of mounting logs, this utility model changes the traditional double roller guiding feeding method and reduces the impact damage of the rolling logs to the step-mounted log machine.

[0046] In this process, the present invention uses a sloping guide frame 35. When the timber rolls onto the woodworking machine via the guide frame 35, it will impact the baffle 38 and push the baffle 38 to move under the impact force. At the same time, the baffle 38, under the action of the gas spring rod 39, can provide a reaction force to the rolling timber, reducing the forward impact of the timber. During this process, the gas spring rod 39 is compressed until the baffle 38 is housed in the mounting groove 37 or slightly flipped up. The timber is stably located above the lifting groove 36, so that the tilting frame 32 can rotate during this process. The timber can be directly lifted and rotated. During the rotation, the timber is transported to the loading points of the first and second timber loading steps 2 and 3, which move up and down repeatedly, thus loading the timber. Since the distance between the rotating frame 32 and the first and second timber loading steps 2 and 3 is short, the rolling impact force is small when the timber leaves the rotating frame 32 and reaches the first timber loading step 2. This reduces the impact damage to the timber loading machine caused by the timber rolling directly through the guide frame 35, and reduces the damage and impact caused by the timber impact.

[0047] In this invention, the synchronous belt drive structure achieves drive through the meshing of the teeth of the synchronous pulley and the synchronous belt. The synchronous belt drive has the characteristics of constant transmission ratio and stable transmission, and is widely used in multi-axis synchronous drive. Those skilled in the art should know this, and this invention will not elaborate further.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
