Technical Field
[0001] This invention relates to the field of structural technology of auxiliary devices for wood processing, and in particular to a log lifting device for wood processing. Background Technology
[0002] Wood processing is the processing of wood as raw material, mainly using mechanical or chemical methods. The finished product retains the basic characteristics of wood. Wood processing technology includes basic processing techniques such as wood cutting, wood drying, wood gluing, and wood surface decoration, as well as functional treatment techniques such as wood protection and wood modification. Cutting methods include sawing, planing, milling, drilling, and sanding. Due to the influence of wood's structure and grain, cutting methods differ from those used for other materials.
[0003] In existing technologies, the wood to be processed is first transported to the processing equipment, then fixed and processed. The wood is sometimes handled by forklifts, and sometimes by manually lifting the logs onto the equipment. Since wood is usually circular in cross-section, logs to be processed in batches are usually stacked together. When they need to be moved, they need to be picked up from top to bottom, and sometimes it is necessary to work at height, which brings certain inconvenience to wood processing. Therefore, we disclose a log lifting device for wood processing to meet people's needs. Summary of the Invention

[0015] In summary, the technical effects and advantages of this invention are as follows:
[0016] 1. In this invention, the logs are first stacked on one side of the outer step assembly using a stacking component. The logs are then moved up and down by the reciprocating movement of the inner step assembly, gradually moving from the stacking component to a higher step on the outer step assembly. Only one log is moved at a time, thus achieving sorting. When the logs reach the highest point, they are rolled onto the processing equipment by a conveying component, where they are then fixed and processed. This method is simple and efficient.
[0017] 2. In this invention, by setting the drive rod, rotating the drive rod and adjusting the inclination of the drive rod, the lateral spacing between multiple waist-shaped sliding holes is reduced. Thus, the spacing between the fixed vertical rod, the first vertical rod, the second vertical rod and the third vertical rod are reduced synchronously through the guide post. This allows the width of the step to be adjusted to accommodate round logs of different sizes, thereby better achieving the goal of lifting a single round log at a time.
[0018] 3. In this invention, the stacking plate is tilted, allowing the stacked logs to automatically roll to the lower side. The side baffles on both sides confine the logs within a certain range, aligning the logs with the center of the inner step assembly. This makes the logs more stable on the inner and outer step assemblies. The support rods can improve the load-bearing capacity of the stacking plate. At the same time, the support rods slide along the linear guide rail, allowing the stacking plate to move synchronously when the inner and outer step assemblies are adjusted.
[0019] 4. In this invention, by setting a rotating support rod, the rotating support rod rotates along the third rotating axis, so that one end of the rotating support rod corresponds to the processing equipment, thereby facilitating the rolling of the log body onto the processing equipment along the rotating support rod. By setting an extension rod, the rotating support rod can be lengthened as needed to better connect and match with the processing equipment and increase the scope of application. The fourth connecting rod can enhance the overall rigidity and better transport the log body.
[0020] 5. In this invention, when the extension rod slides to the appropriate position, the sawtooth teeth of the limiting pin are engaged with the rack to limit the movement of the extension rod and achieve the limiting function. Through the setting of the tension spring, the tension spring can pull the limiting pin to one side of the rack and maintain the engagement state, while preventing the limiting pin from easily slipping off the rack.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Example: Reference Figure 1-8The diagram shows a log lifting device for wood processing, comprising a base 1. A fixed plate 3 is mounted on the top side of the base 1 via multiple columns 2. The top side of the fixed plate 3 has an opening forming a U-shape. A movable pallet 12 is slidably mounted on the bottom side of the fixed plate 3 via a guide unit. The movable pallet 12 corresponds to the opening on the fixed plate 3. A first telescopic cylinder 7 is vertically mounted on the top side of the base 1, with its extended end connected to the bottom side of the movable pallet 12. An outer step assembly 4 is mounted on the top side of the fixed plate 3, and an inner step assembly 5 is mounted on the top side of the movable pallet 12. A stacking assembly is mounted on one side of the outer step assembly 4, and a conveying assembly 10 is mounted on the other side. Both the outer step assembly 4 and the inner step assembly 5... It consists of two sets of fixed vertical rods 51, a first vertical rod 52, a second vertical rod 53, a third vertical rod 54, and multiple horizontal rods 55. The bottom ends of the two sets of fixed vertical rods 51, the first vertical rod 52, the second vertical rod 53, and the third vertical rod 54 are installed in parallel on the top side of the fixed plate 3 or the top side of the movable support plate 12. The top ends of the fixed vertical rods 51, the first vertical rod 52, the second vertical rod 53, and the third vertical rod 54 are connected in sequence to form a stepped structure. The horizontal rods 55 are at a certain sharp angle to the horizontal direction, making the horizontal rods 55 tilted. The outer step assembly 4 and the inner step assembly 5 match each other to form a new stepped structure. An adjustment assembly for adjusting the tilt angle of the horizontal rods 55 is installed on one side of both the outer step assembly 4 and the inner step assembly 5.
[0033] Based on the above structure, the log bodies 14 are first stacked on one side of the outer step assembly 4 using the stacking assembly. When the inner step assembly 5 is in the bottom position, the top of the third vertical bar 54 on the inner step assembly 5 is lower than the stacking assembly, causing the stacked log bodies 14 to automatically roll to the bottommost step on the inner step assembly 5. At this time, the width of the step is close to the diameter of the log body 14, so only one log body 14 can be accommodated on the bottommost step of the inner step assembly 5 at a time. At this time, the first telescopic cylinder 7 extends, raising the inner step assembly 5 and aligning the lowest step of the inner step assembly 5 with the lowest step of the outer step assembly 4. At this time, the horizontal bar 55 is in an inclined state. The log body 14 on the inner step assembly 5 automatically rolls to the step of the outer step assembly 4. At this time, the first telescopic cylinder 7 shortens, causing the inner step assembly 5 to descend. The log body 14 then stops on the outer step assembly 4. Simultaneously, the log body 14 on the stacking rack rolls to the inner step assembly 5. Similarly, when the first telescopic cylinder 7 extends again, the log body 14 is transferred from the outer step assembly 4 to a higher step. In this way, the log body 14 gradually moves to the highest point, and only one log body 14 is moved at a time, achieving sorting. When the log body 14 moves to the highest point, it is rolled to the processing equipment through the material conveying assembly, and then fixed and processed. This process is simple and efficient.
[0034] like Figure 1 and5 As shown, the guide unit includes multiple vertical guide posts 15. The top side of the multiple vertical guide posts 15 is installed on the bottom side of the fixed plate 3. The bottom side of the movable tray 12 is correspondingly installed with multiple L-shaped fixing blocks 17. Each of the multiple L-shaped fixing blocks 17 has a sliding hole. The sliding hole slides and matches the corresponding vertical guide post 15. Through the setting of the vertical guide posts 15, the movable tray 12 slides along the vertical guide posts 15 through the L-shaped fixing blocks 17, making the movable tray 12 more stable when moving up and down.
[0035] like Figure 1-3 As shown, the adjustment assembly includes a drive rod 591, a fixed vertical rod 51, a first vertical rod 52, a second vertical rod 53, and a third vertical rod 54, which are rotatably connected to corresponding horizontal rods 55 via a first rotating shaft 56, forming a stepped structure. The bottom ends of the first vertical rod 52, the second vertical rod 53, and the third vertical rod 54 are slidably mounted on the top side of the fixed plate 3 or the movable support plate 12 via sliding units. One end of the drive rod 591 is rotatably mounted on one side of the third vertical rod 54 via a second rotating shaft 57. Multiple oblong sliding holes 595 are evenly provided along the length of the drive rod 591. The fixed vertical rod 51, the first vertical rod 52, and the second vertical rod 53... Guide posts 58 are installed on one side of each step. The guide posts 58 slide and match the corresponding waist-shaped sliding holes 595. A push unit is installed at one end of the drive rod 591. By rotating the drive rod 591, the inclination of the drive rod 591 is adjusted, thereby reducing the lateral distance between the multiple waist-shaped sliding holes 595. As a result, the distance between the fixed vertical rod 51, the first vertical rod 52, the second vertical rod 53 and the third vertical rod 54 is reduced synchronously through the guide posts 58. This allows the width of the step to be adjusted to accommodate log bodies 14 of different sizes, thus better enabling the lifting of a single log body 14 at a time.
[0036] like Figure 4 As shown, rollers 581 are fitted onto each guide post 58. The rollers 581 are matched with the corresponding waist-shaped sliding holes 595. By setting the rollers 581, the friction between the drive rod 591 and the guide post 58 can be reduced, so that the mechanism can run more smoothly.
[0037] like Figure 4 As shown, the sliding unit includes a linear guide rail 11, which is installed on the top side of the fixed plate 3 or the movable support plate 12. The bottom ends of the first vertical rod 52, the second vertical rod 53 and the third vertical rod 54 are all equipped with sliders 16. The sliders 16 slide and match with the corresponding linear guide rails 11. By setting the linear guide rails 11, the first vertical rod 52, the second vertical rod 53 and the third vertical rod 54 slide along the linear guide rails 11 through the sliders 16 to realize the adjustment of the spacing.
[0038] like Figure 3 and 4As shown, the pushing unit includes a second telescopic cylinder 592. A first connecting rod 594 is installed on one end of each of the two drive rods 591 away from the second rotating shaft 57. U-shaped seats 593 are installed on the top sides of both the fixed plate 3 and the movable support plate 12. One end of the second telescopic cylinder 592 is rotatably connected to the corresponding U-shaped seat 593 through a rotating shaft. The telescopic end of the second telescopic cylinder 592 is rotatably connected to the first connecting rod 594. Through the setting of the second telescopic cylinder 592, the drive rod 591, the second telescopic cylinder 592, and the fixed plate 3 form a triangular structure. The length is changed by the telescopic movement of the second telescopic cylinder 592, and the angle of the drive rod 591 is adjusted.
[0039] like Figure 1 and 2 As shown, the stacking assembly includes a stacking plate 8. One side of the stacking plate 8 is installed on one side of the third vertical rod 54 located on the top side of the fixed plate 3. A notch is provided on one side of the stacking plate 8 to avoid the inner step assembly 5. Side baffles 9 are installed on both sides of the stacking plate 8 to form a U-shaped structure. A support rod 13 is installed on the bottom side of the stacking plate 8. A sliding block is installed at the bottom end of the support rod 13. The sliding hole is slidably matched with the linear guide rail 11. The stacking plate 8 is in an inclined state, so that the stacked log body 14 can automatically roll to the lower side. The side baffles 9 on both sides limit the log body 14 within a certain range, so that the log body 14 is aligned with the middle of the inner step assembly 5, making the log body 14 more stable on the inner step assembly 5 and the outer step assembly 4. The support rod 13 can improve the load-bearing capacity of the stacking plate 8. At the same time, the support rod 13 slides along the linear guide rail 11, so that the stacking plate 8 can move synchronously when the inner step assembly 5 and the outer step assembly 4 are adjusted.
[0040] like Figure 1 and 6 As shown, the conveying assembly 10 includes two rotating rods 101. One end of each of the two rotating rods 101 is rotatably mounted on one side of the first vertical rod 52 located on the top side of the fixed plate 3 via a third rotating shaft 109. A second connecting rod 102 is installed on the side of the two rotating rods 101 that is close to each other, and a third connecting rod 103 is installed on the side of the two first vertical rods 52 that is close to each other. A third telescopic cylinder 104 is rotatably sleeved on the third connecting rod 103. The extended end of the third telescopic cylinder 104 is rotatably connected to the second connecting rod 102. An extension unit is installed on one end of the rotating rod 101. By setting the rotating rod 101, the rotating rod 101 rotates along the third rotating shaft 109, so that one end of the rotating rod 101 corresponds to the processing equipment, thereby facilitating the rolling of the log body 14 onto the processing equipment along the rotating rod 101.
[0041] like Figure 6As shown, the extension unit includes two extension rods 105, and one end of each of the two rotating support rods 101 is provided with a first sliding hole. The two extension rods 105 are slidably installed in the corresponding first sliding holes. A fourth connecting rod 106 is installed at one end of each of the two extension rods 105. A limit unit 108 is installed between the extension rods 105 and the rotating support rods 101. By setting the extension rods 105, the rotating support rods 101 can be lengthened as needed to better connect and match with the processing equipment and increase the scope of application. The fourth connecting rod 106 can enhance the overall rigidity and better transport the log body 14.
[0042] like Figure 7 As shown, the limiting unit 108 includes a limiting pin 1801. A second sliding hole communicating with the first sliding hole is provided on one side of the rotating support rod 101. The limiting pin 1801 is slidably installed in the second sliding hole. A flange plate 1802 is installed at one end of the limiting pin 1801, and a sawtooth is provided at the other end. A groove is provided on one side of the extension rod 105, and a rack 107 is installed in the groove. The sawtooth on the limiting pin 1801 is inserted and matched with the rack 107. A tension spring 1803 is sleeved on the limiting pin 1801. One end of the spring 1803 is mounted on the rotating support rod 101, and the other end is mounted on one side of the flange plate 1802. When the extension rod 105 slides to the appropriate position, the sawtooth teeth of the limiting pin 1801 are engaged with the rack 107 to limit the movement of the extension rod 105 and realize the limiting function. Through the setting of the tension spring 1803, the tension spring 1803 can pull the limiting pin 1801 to one side of the rack 107 and keep it engaged, while preventing the limiting pin 1801 from easily slipping off the rack 107.
[0043] Working principle of this invention:
[0044] First, the log bodies 14 are stacked on one side of the outer step assembly 4 using the stacking assembly. When the inner step assembly 5 is in the bottom position, the top of the third vertical bar 54 on the inner step assembly 5 is lower than the stacking assembly, causing the stacked log bodies 14 to automatically roll onto the bottommost step of the inner step assembly 5. At this time, the width of the step is close to the diameter of the log body 14, so only one log body 14 can be accommodated on the bottommost step of the inner step assembly 5 at a time. Then, the first telescopic cylinder 7 extends, raising the inner step assembly 5 and aligning the lowest step of the inner step assembly 5 with the lowest step of the outer step assembly 4. At this time, because the horizontal bar 55 is in an inclined state, the log body 14 is automatically rolled onto the bottommost step of the inner step assembly 5. The log body 14 on the inner step assembly 5 automatically rolls to the step of the outer step assembly 4. At this time, the first telescopic cylinder 7 shortens, causing the inner step assembly 5 to descend. The log body 14 then stops on the outer step assembly 4. Simultaneously, the log body 14 on the stacking rack rolls to the inner step assembly 5. Similarly, when the first telescopic cylinder 7 extends again, the log body 14 is transferred from the outer step assembly 4 to a higher step. In this way, the log body 14 gradually moves to the highest point, and only one log body 14 is moved at a time, achieving sorting. When the log body 14 moves to the highest point, it is rolled to the processing equipment through the material conveying assembly, and then fixed and processed. It is simple and efficient.
[0045] By rotating the drive rod 591, the tilt of the drive rod 591 is adjusted, reducing the lateral spacing between the multiple waist-shaped sliding holes 595. This, in turn, causes the spacing between the fixed vertical rod 51, the first vertical rod 52, the second vertical rod 53, and the third vertical rod 54 to decrease synchronously via the guide post 58. This allows for adjustment of the step width to accommodate log bodies 14 of different sizes, thus better enabling the lifting of a single log body 14 at a time. The stacking plate 8 is tilted, allowing the stacked log bodies 14 to automatically roll to the lower side. The side baffles 9 confine the log bodies 14 within a certain range, aligning them with the center of the inner step assembly 5, ensuring the log bodies 14 are within the inner step assembly. The inner and outer step components 5 and 4 are more stable. The support rod 13 can improve the load-bearing capacity of the stacking plate 8. At the same time, the support rod 13 slides along the linear guide rail 11, so that the stacking plate 8 can move synchronously when the inner step component 5 and the outer step component 4 are adjusted. By setting the rotating support rod 101, the rotating support rod 101 rotates along the third rotating shaft 109, so that one end of the rotating support rod 101 corresponds to the processing equipment, thereby facilitating the rolling of the log body 14 onto the processing equipment along the rotating support rod 101. By setting the extension rod 105, the rotating support rod 101 can be lengthened as needed to better connect and match with the processing equipment and increase the applicable range. The fourth connecting rod 106 can enhance the overall rigidity and better transport the log body 14.
