Description

Technical Field

[0001] The present application relates to the technical field of wood processing, and in particular to a backing structure for transporting wood. Background Art

[0002] In the process of wood processing, a backer is often needed. With the backer, the wood can move along the straight line of the backer, or lean on the backer without moving, and the tool can also move along the straight line of the backer.

[0003] In the process of conveying wood before cutting, the backrest is one of the indispensable structures. When transporting wood, the main function of the backrest is to support the wood, that is, by supporting one side of the wood with the backrest, the wood can always keep sliding along the straight direction of the backrest during the process of conveying to the cutting saw table, thereby ensuring that the conveying angle position of the wood will not shift, thereby ensuring that the wood can be cut along the designated cutting line later, so as to facilitate the cutting and processing of larger wood into multiple regularly shaped plates, spirals or bars.

[0004] In the prior art, during the transportation process of wood before cutting, the backrest is usually fixed directly to the frame by bolts to limit the wood in transportation. During use, the position of the backrest is fixed and cannot be adjusted. When the size of the transported wood is not fixed, especially when the size of the transported wood is small and cannot be abutted against the backrest, it is easy for the wood to shift during transportation, resulting in subsequent wood cutting errors, which is inconvenient to use. Utility Model Content

[0005] In order to adjust the position of the backrest according to the size of the wood during the wood transportation process and ensure that the backrest can adapt to wood of different sizes, thereby ensuring the accuracy of subsequent processing of the wood, the present application provides a backrest structure for transporting wood.

[0006] The present application provides a backing structure for transporting wood, which adopts the following technical solution:

[0007] A backrest structure for transporting wood, comprising a frame and a backrest arranged on the frame, wherein the frame is fixedly connected to a first mounting seat, the first mounting seat is fixedly connected to a rotating shaft, a fixed block is rotatably connected to the rotating shaft, the fixed block is slidably connected to a connecting rod at one end away from the rotating shaft, one end of the connecting rod is fixedly connected to the backrest, the connecting rod slides on the first mounting seat along the length direction of the frame, the first mounting seat is provided with a driving assembly for driving the fixed block to rotate, and the frame is provided with a limiting assembly for limiting the moving direction of the backrest.

[0008] By adopting the above technical solution, the fixed block is driven to rotate by the driving component during use, and the rotation of the fixed block drives the connecting rod to move along the length direction of the frame, and the movement of the connecting rod drives the backrest to move synchronously, and then the moving direction of the backrest is limited by the limiting component, so that the sliding of the backrest along the length direction of the frame is converted into sliding in the width direction of the frame, so as to adjust the position of the backrest according to the size of the wood, thereby ensuring that the backrest can abut against the side wall of the wood.

[0009] Preferably, a U-shaped groove is formed at one end of the fixing block away from the rotating shaft, a waist-shaped hole is formed on the first mounting seat, one end of the connecting rod is embedded in the U-shaped groove, and the other end passes through the waist-shaped hole and is slidably connected to the backrest.

[0010] By adopting the above technical solution, when the fixed block rotates during use, one end of the connecting rod arranged on the fixed block makes a circular motion. At this time, by limiting the connecting rod in the U-shaped groove, it is ensured that the backrest can only slide along the length direction of the frame, and is not affected by the height direction force from the frame when the fixed block rotates, thereby ensuring that the adjustment direction of the backrest is not affected.

[0011] Preferably, the driving assembly includes a rocker fixedly connected to the fixed block and a handle fixedly connected to the rocker, the fixed block and the handle are respectively located at two ends of the rocker, the rocker is slidably connected to the first mounting seat, and the rocker is provided with a first positioning structure for positioning itself after rotation.

[0012] By adopting the above technical solution, when in use, the staff holds the handle and shakes the handle to drive the rotation of the fixed block to adjust the position of the backrest. After the adjustment is completed, the rocker is positioned by the first positioning structure to fix the position of the backrest.

[0013] Preferably, the first positioning structure comprises a locking bolt threadedly connected to the rocker.

[0014] By adopting the above technical solution, the locking bolt is screwed to make it abut against the side wall of the first mounting seat during use, so that the rocker is limited by the friction between the locking bolt and the side wall of the first mounting seat, which is simple and convenient to use.

[0015] Preferably, the position limiting components are provided in a plurality of groups, and the plurality of groups of position limiting components are evenly spaced along the length direction of the rack.

[0016] By adopting the above technical solution, since the backrest itself has a certain length during use, the stability of the backrest during position adjustment is ensured through the joint action of multiple groups of limiting components, thereby facilitating the adjustment of the position of the backrest and facilitating use.

[0017] Preferably, the limiting assembly includes a second mounting base fixedly connected to the frame, a rotating rod rotatably connected to the second mounting base, and a swing block fixedly connected to one end of the rotating rod, and the end of the swing block away from the rotating rod is rotatably connected to the backrest.

[0018] By adopting the above technical solution, when the connecting rod slides along the length direction of the frame during use, the backrest has a tendency to slide in the length direction of the frame, and then through the coordinated use of the rotating rod and the swing block, the backrest can only make circular motion with the axis of the rotating rod as the rotation axis, so that the backrest can slide along the width direction of the frame while sliding along the length direction of the frame, thereby realizing the adjustment of the distance between the backrest and the wood.

[0019] Preferably, the second mounting seat includes a seat body fixedly connected to the frame, and a slider arranged on the seat body, the seat body is provided with a sliding groove, the slider slides in the sliding groove along the height direction of the frame, one end of the rotating rod is rotatably connected to the slider, and the other end is located outside the sliding groove after passing through the second mounting seat, the swing block is fixedly connected to the end of the rotating rod located outside the sliding groove, and the rotating rod is provided with a second positioning structure for positioning the slider.

[0020] By adopting the above technical solution, when in use, the staff manually adjusts the height of the slider according to the size of the wood, thereby adjusting the height of the backrest. After adjustment, the height is fixed by the second positioning structure, thereby ensuring the normal use of the backrest, which is beneficial to improving the applicability of the overall structure.

[0021] Preferably, the second positioning structure comprises a positioning bolt threadedly connected to the rotating rod, and the positioning bolt abuts against an outer side wall of the second mounting seat.

[0022] By adopting the above technical solution, when in use, the staff screws the positioning bolt so that the positioning bolt abuts against the outer wall of the second mounting seat, thereby limiting the rotating rod and preventing the rotating rod from sliding downward, thereby fixing the backing position.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When in use, the fixed block is driven to rotate by shaking the handle, driving the connecting rod to slide along the length direction of the frame. Under the restriction of the swing block, the backrest can only slide along the length direction of the frame by rotating around the axis of the rotating rod as the center of the circle, thereby realizing the sliding of the connecting rod along the length direction of the frame, driving the backrest to adjust the position in the width direction of the frame. After adjustment, the rocker is locked and positioned by the locking bolt, which is simple and convenient to use;

[0025] 2. When in use, a U-shaped groove is opened on the fixed block. When the fixed block rotates, the inner wall of the U-shaped groove abuts and limits the connecting rod, so that the connecting rod moves along the length direction of the frame, avoiding the connecting rod from slipping along the height direction of the frame, thereby ensuring the stability of the backrest when moving;

[0026] 3. When in use, the height of the backrest can be adjusted by adjusting the height of the slider to adjust the height of the backrest from the top surface of the frame to meet the needs of transporting wood of different sizes. The second mounting seat is then abutted against the positioning bolt to position the rotating rod to prevent the rotating rod and the slider from sliding down simultaneously, thereby fixing the backrest.

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with Figures 1 to 5.

[0034] The embodiment of the present application discloses a backing structure for transporting wood.

[0035] Reference Figure 1A backrest structure for transporting wood comprises a frame 1 placed horizontally on the ground, a conveyor belt 20 is installed on the frame 1, a backrest 2 is arranged on one side of the top surface of the frame 1, the backrest 2 is located on one side of the conveyor belt 20, the backrest 2 is a rectangular block structure in the shape of an elongated strip as a whole, and the bottom surface of the backrest 2 abuts against the top surface of the frame 1; when in use, the wood is transported to the frame 1, and the side of the wood is abutted against the backrest 2 to ensure that when the wood is transported with the conveyor belt 20, the side of the wood abuts against the backrest 2, thereby preventing the two ends of the wood from swinging and causing the overall deviation of the wood, thereby ensuring that the wood can enter the cutting equipment normally when it is subsequently moved to the cutting equipment.

[0036] 1 and 2, a first mounting seat 3 is provided on the side wall of the frame 1. The first mounting seat 3 is a fan-shaped block structure as a whole. The top surface of the first mounting seat 3 is an arc surface. A mounting cavity 33 is provided on the first mounting seat 3. The inner wall of the mounting cavity 33 is fixedly connected to a rotating shaft 4. A fixed block 5 is rotatably connected to the rotating shaft 4. A U-shaped groove 51 is provided at one end of the fixed block 5 away from the rotating shaft 4. A waist-shaped hole 31 is provided on the inner wall of the first mounting cavity 33. The length direction of the waist-shaped hole 31 is parallel to the length direction of the frame 1. The first mounting cavity 33 is provided with a A connecting rod 6 is provided, one end of which is embedded in the U-shaped groove 51, and the other end is fixedly connected to the backrest 2 after passing through the waist-shaped hole 31. A driving component 7 is provided in the mounting cavity 33. When in use, the fixing block 5 is driven to rotate by the driving component 7, and the connecting rod 6 slides along the length direction of the waist-shaped hole 31 under the limitation of the inner wall of the waist-shaped hole 31. At the same time, the connecting rod 6 is embedded in the U-shaped groove 51 to prevent the connecting rod 6 from being unable to move due to the abutment of the inner wall of the waist-shaped hole 31 when making a circular motion.

[0037] 2 and 3 , a long strip-shaped guide hole 32 is provided on the first mounting seat 3. The guide hole 32 is located on the top surface of the first mounting seat 3. The guide hole 32 is connected to the mounting cavity 33. The driving assembly 7 includes a rocker 71 and a handle 72. One end of the rocker 71 is fixedly connected to the fixed block 5, and the other end is a movable end. The movable end of the rocker 71 slides in the guide hole 32. The movable end of the rocker 71 is fixedly connected to the handle 72. The handle 72 is located outside the mounting cavity 33. A first positioning structure 9 is provided on the rocker 71. The first positioning structure 9 is used to position the rotated rocker 71. When in use, the rocker 71 is driven to rotate by rotating the handle 72, thereby driving the fixed block 5 to rotate synchronously, thereby driving the backrest 2 to move. After the backrest 2 is adjusted to the specified position, the rocker 71 can be fixed and limited by the first positioning structure 9, thereby achieving fixation of the backrest 2.

[0038] 2 and 3 , the first positioning structure 9 includes a locking bolt 91, which is located in the mounting cavity 33, and the locking bolt 91 is threadedly connected to the rocker arm 71; when in use, after the rocker arm 71 is adjusted, the staff twists the locking bolt 91 so that the locking bolt 91 abuts against the inner wall of the mounting cavity 33, thereby relying on the friction between the locking bolt 91 and the inner wall of the mounting cavity 33 for positioning, thereby fixing the position of the rocker arm 71, which is simple and convenient to use.

[0039] 1 , a limit assembly 8 is further installed on the frame 1, and the limit assembly 8 is used to limit the moving direction of the backrest 2. In order to improve the stability of the movement of the backrest 2, a plurality of limit assemblies 8 are provided, and the plurality of limit assemblies 8 are arranged at intervals along the length direction of the frame 1. In the present embodiment, the limit assembly 8 is preferably arranged in two groups, and the two groups of limit assemblies 8 are respectively located on both sides of the first mounting seat 3; when in use, the two groups of limit assemblies 8 are used in coordination to improve the stability of the backrest 2 during movement.

[0040] 1 and 4, the limiting assembly 8 comprises a second mounting seat 81, a rotating rod 82 and a swing block 83. The second mounting seat 81 is fixedly connected to the frame 1 by bolts. One end of the rotating rod 82 is rotatably connected to the second mounting seat 81, and the other end is fixedly connected to the swing block 83. The end of the swing block 83 away from the rotating rod 82 is rotatably connected to the top of the backrest 2. When in use, when the staff shakes the handle 72 to drive the fixed block 5 to rotate, the backrest 2 has a tendency to slide along the length direction of the frame 1. Under the limitation of the rotating rod 82 and the swing block 83, the swing block 83 makes a circular motion with the axis of the rotating rod 82 as the center, thereby driving the backrest 2 to make a circular motion, thereby realizing the sliding of the backrest 2 along the width direction of the frame 1.

[0041] 4 and 5, the second mounting seat 81 includes a seat body 811 and a slider 812. The seat body 811 is fixed to the frame 1 by bolts. A sliding groove 813 is provided on the seat body 811. The slider 812 slides in the sliding groove 813 along the height direction of the frame 1. One end of the rotating rod 82 rotates on the slider 812, and the other end of the rotating rod 82 passes through the second mounting seat 81 and is fixedly connected to the swing block 83. When in use, transporting wood of different sizes may require different sizes of backrests 2 to ensure the transportation of wood. The distance between the top surface of the backrests 2 of different sizes and the top surface of the frame 1 is different. Therefore, when in use, the height of the slider 812 is adjusted according to the size of the backrest 2, thereby adjusting the height of the swing block 83 so that the swing block 83 is always located on the top surface of the backrest 2.

[0042] Reference Figure 4 and Figure 5A second positioning structure 10 is provided on the rotating rod 82, and the second positioning structure 10 is used to position the rotating rod 82 after movement. The second positioning structure 10 includes a positioning bolt 101, and the positioning bolt 101 is threadedly connected to the rotating rod 82, and the positioning bolt 101 is located above the second mounting seat 81; when in use, the staff screws the positioning bolt 101 so that the positioning bolt 101 abuts against the top surface of the second mounting seat 81, thereby fixing the position of the slider 812, thereby preventing the slider 812 from driving the rotating rod 82 and the swing block 83 to descend.

[0043] The implementation principle of the embodiment of the present application is as follows: when in use, the staff drives the rocker 71 to rotate by shaking the handle 72 according to the size of the transported wood, and the rotation of the rocker 71 drives the fixed block 5 to rotate. Under the abutment limit of the inner wall of the U-shaped groove 51, the rotation of the fixed block 5 drives the connecting rod 6 to rotate. Since the connecting rod 6 slides in the waist-shaped hole 31, the inner wall of the waist-shaped hole 31 abuts and limits the connecting rod 6, so that the connecting rod 6 only slides along the length direction of the frame 1, so that the backrest 2 has a tendency to slide along the length direction of the frame 1. A swing block 83 is rotatably connected, the swing block 83 is fixedly connected to the rotating rod 82, and the rotating rod 82 is rotatably connected to the slider 812. When the backrest 2 slides along the length direction of the frame 1, the swing block 83 makes a circular motion with the rotating rod 82 as the center, so that the motion trajectory of the backrest 2 is arc-shaped, that is, when the backrest 2 slides along the length direction of the frame 1, it will also be offset along the width direction of the frame 1, so as to adjust the position of the backrest 2. The overall operation only relies on the mechanized structure to realize the conversion of the sliding direction of the backrest 2, which is simple and convenient to use.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
