Description

Technical Field

[0002] Wooden pallets are pallets made of natural wood. They are the most widely used pallets. Pallets are horizontal platform devices used for packaging, stacking, handling and transportation of goods and products as unit loads. They are generally made of wood, metal, and fiberboard, which are convenient for loading and unloading, and handling unit materials and small quantities of materials. The types of pallets are mainly made of wood, plastic, metal and other materials. Wood is the most widely used now because it is cheap and strong.

[0003] When assembling wooden pallets, the panels need to be flat and of uniform size to ensure stable placement of items and stacking of wooden pallets. Therefore, the wooden boards must be planed stably to ensure they are flat and have small dimensional errors.

[0004] After searching, it is found that Chinese patent documents disclose an adjustable multifunctional electric planer for wooden pallets [Application No.: 202020800088.6; Publication No.: CN213081714U]. This electric planer includes a base, a slider, a fastening screw and an electric planer body. A first vertical plate is welded to one end of the top of the base, and the electric planer body is fixed to one side of the top of the first vertical plate by a fastening screw. A slide rail is installed on one side of the first vertical plate by screws, and a column is provided on the upper end of the slide rail. A fixed block is welded to the top of the column, and adjusting screws are installed on both ends of the top of the fixed block by threaded grooves. A reserved groove is provided on one side of the fixed block. Although it is convenient to clamp and fix the wooden board, and it is convenient to move and feed the clamped wooden board, and it is convenient to planing, but it is not stable enough when feeding and discharging, and it is easy to have the phenomenon of gnawing the head and tail, that is, the head and tail will be planed thinner during planing, and double-sided planing cannot be performed, and the planing accuracy is low.

[0005] Based on this, we propose a double-sided planer device for wooden pallet processing, which can stably perform fixed-width sawing and double-sided planing on wooden pallet boards, and can stably clamp and transport the boards to avoid the phenomenon of gnawing the head and tail when planing the boards; it can quickly collect cut and planed wood chips.

[0064] Working principle of the present invention:

[0065] According to the planing surface size requirements of the wood board, the position of the limit mechanism 2 is adjusted, that is, the telescopic end of the limit push rod 11 drives the stop plate 12 to slide on the wood saw platform 9, thereby adjusting the distance between the stop plate 12 and the band saw 10, and this distance is the thickness of the wood board after the saw blade is processed;

[0066] The sliding seat 13 slides on the wood saw platform 9, the inner side wall of the frame plate 20 is flush with the band saw 10, and the position of the sliding seat 13 is locked with the locking bolt 14;

[0067] The sliding plate 22 slides on the moving frame 50, the inner side wall of the frame plate 20 is flush with the L-shaped fixing plate 24, and the position of the sliding plate 22 is locked with the locking screws 23;

[0068] The telescopic end of the sliding push rod 18 is telescopic to adjust the distance of the sliding frame 17, thereby adjusting the distance between the active roller 15 and the frame plate 20, and the distance between the active rollers 15 of the two symmetrical feeding components 25, so as to clamp and convey the cut wood board and the planed wood board to avoid the phenomenon of gnawing the head and the tail. After the active roller 15 is powered on, it rotates to clamp and convey the wood board, and the two rotating rollers 19 rotate to convey the wood board, reducing friction and making the conveying more stable;

[0069] According to the thickness requirement of the wood board, the adjusting handle 30 is rotated, and the adjusting handle 30 drives one of the adjusting screw rods 35 to rotate, and then drives the other adjusting screw rod 35 to rotate through the synchronous sprocket pair 33, that is, drives the lifting seat 62 to slide along the four slide bars 34, so as to adjust the distance between the planing rollers 46 of the two planing assemblies 26. The adjustment position is observed through the scale line 32, and the adjustment is completed;

[0070] The locking screw 37 is rotated, and the locking screw 37 pushes the two elastic plates 66 to open, thereby driving the sliding rods 67 at both ends of the elastic plate 66 to slide outward inside the sliding seat 36, driving the locking block 68 to contact the sliding rod 34 at the corresponding position, thereby locking the lifting seat 62, and engaging the locking seat 64 with the fixed seat 63, and then engaging the lock buckle 65 on the lifting seat 62, locking the locking screw 37, and ensuring that the position of the lifting seat 62 remains stable;

[0071] The movable frame 50 can be moved to facilitate the movement of the adjustment mechanism 6. The output shaft of the adjustment motor 49 drives the adjustment screw 53 to rotate.

The semi-finished product after slicing, the front feeding assembly 25 cooperates with the frame plate 20 to stably convey the cut wooden board, and the other two feeding assemblies 25 cooperate. After the active roller 15 is powered on, it rotates to clamp and convey the wooden board. The two rotating rollers 19 rotate to convey the wooden board, reduce friction, stably convey the cut wooden board, and convey the wooden board to the inside of the double-sided planing mechanism 5 to avoid the phenomenon of gnawing the head of the planed wooden board;

[0073] The switch buttons 29 of the two planing assemblies 26 are turned on to start the planing motor 31. The output shaft of the planing motor 31 drives the planing roller 46 to rotate through the second belt pulley pair 42 to plan the template. One end of the planing roller 46 drives the wind wheel shaft of the exhaust fan 39 to rotate through the first belt pulley pair 40 to perform dust collection. The other end of the planing roller 46 drives the reduction gear pair 44 to rotate. The reduction gear pair 44 drives one of the conveying rollers 47 through the transmission sprocket pair 45. One of the conveying rollers 47 drives the other conveying roller 47 to rotate through the transmission sprocket pair 45 to convey the template.

[0074] The planed wood board is transported to the second limit mechanism 4 after double-sided planing. Two symmetrically arranged feeding components 25 are used to clamp and transport the planed wood board to avoid the tail biting phenomenon of the planed wood board and stabilize the output;

[0075] Start the air duct 60, and the air outlet pipe 61 is connected to the air duct 60 through a pipeline, so that negative pressure is formed inside the sedimentation cylinder 54. When the band saw 10 is sliced ​​through the dust collecting cover, the cut wood chips and the debris generated by the double-sided planing mechanism 5 during double-sided planing, and the planed wood chips discharged through the air outlet of the exhaust fan 39, enter the sedimentation cylinder 54 through the pipeline and the air inlet pipe 56, and settle downward and enter the mobile dust collecting cylinder 57. After a period of time, the sedimentation cylinder 54 is pulled up, and the mobile dust collecting cylinder 57 is pulled out through the dust collecting handle 58 to discharge the wood chips inside.

[0076] In summary, the wood sawing machine 1 cooperates with the limiting mechanism 2 to achieve stable control of the thickness of the wood board after being processed by the saw blade, convenient adjustment, and stable material discharge;

[0077] The first limiting mechanism 3 and the second limiting mechanism 4 cooperate to stably clamp and convey the cut and planed wooden board, so as to avoid the phenomenon of gnawing the head and tail when planing the wooden board;

[0078] The double-sided planing mechanism 5 cooperates with two symmetrically arranged feeding plates 27 and the planing components 26 arranged on both sides of the two feeding plates 27 to achieve stable and efficient planing of both sides of the wooden board;

[0079] The planing assembly 26 cooperates with the two adjusting screw rods 35 through the lifting seat 62 to stably adjust the planing thickness. The adjusted lifting seat 62 is also locked through the lifting seat 62 and the locking assembly to ensure a stable position and planing accuracy.
