Description

Technical Field

[0001] This utility model relates to the field of double-end saw technology, and in particular to a double-end saw for cutting timber. Background Technology

[0002] In the furniture manufacturing, construction and decoration, and wood product manufacturing industries, it is often necessary to cut long timber into short timber of specific lengths. Traditional cutting methods often use single-head table saws or manual hand-held cutting machines. However, this method has the following significant drawbacks: First, it requires cutting one end first and then turning the saw around to cut the other end, which is a cumbersome process with low production efficiency. Second, the two clamping and positioning operations can easily lead to cumulative errors, resulting in uneven cuts at both ends of the workpiece, inconsistent length dimensions, and poor processing accuracy. Finally, the operator needs to be in close contact with the saw blade, which poses a significant safety hazard.

[0003] Currently, there are some double-end saws on the market, but they are usually complex in structure and expensive. They are also not good at pressing and positioning timber during the transportation process. During cutting, the timber is prone to displacement or vibration, which still affects the cutting accuracy and cut quality. Therefore, a double-end saw for timber cutting is proposed to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-5 As shown, the present invention proposes a double-end saw for cutting timber, comprising two support plates 1, a support rod 2 between opposite sides of the two support plates 1, two mounting plates 3 slidably connected to the top of the two support rods 2, and a spacing adjustment mechanism 4 between opposite sides of the two support plates 1, the spacing adjustment mechanism 4 being connected to the mounting plates 3 for adjusting the spacing between the two mounting plates 3.

[0023] A mounting frame 5 is installed on the top of each of the two mounting plates 3. A cutting mechanism 6 is installed inside the mounting frame 5. A conveying mechanism 7 is installed on the opposite side of each of the two mounting frames 5. A pressing mechanism 8 is installed on the top of each of the two mounting frames 5.

[0024] In this utility model, the mounting plate 3 can be supported by the support plate 1 and the support rod 2, and the spacing between the two mounting plates 3 can be adjusted by the spacing adjustment mechanism 4, thereby adjusting the spacing between the cutting mechanism 6, the conveying mechanism 7 and the pressing mechanism 8, so as to facilitate the cutting of wood squares of different lengths.

[0025] The cutting mechanism 6 and the conveying mechanism 7 enable automatic conveying and simultaneous cutting of timber at both ends, completing fixed-length processing in one go, completely avoiding secondary clamping, and achieving extremely high production efficiency. The pressing mechanism 8 can firmly press the timber during cutting, effectively preventing vibration and displacement of the timber, ensuring a flat and smooth cut, and ensuring the cutting quality of the timber.

[0026] In Embodiment 1, the spacing adjustment mechanism 4 includes a servo drive motor 41 installed on the outside of one of the support plates 1. A bidirectional threaded rod 42 extending to the opposite side of the two support plates 1 is installed on the output shaft of the servo drive motor 41. Displacement blocks 43 are threaded to both ends of the bidirectional threaded rod 42 with opposite thread directions. The tops of the two displacement blocks 43 are respectively connected to the bottoms of the two mounting plates 3. When the servo drive motor 41 is started, the output shaft of the servo drive motor 41 will drive the bidirectional threaded rod 42 to rotate. Under the action of the thread thrust, the two ends of the bidirectional threaded rod 42 with opposite thread directions will respectively drive the two displacement blocks 43 to move to the opposite side or the opposite side. The two displacement blocks 43 will respectively drive the two mounting plates 3 to move to the opposite side or the opposite side.

[0027] Two guide rods 44 are installed between the opposite sides of the two support plates 1. The mounting plate 3 is slidably connected to the outside of the two guide rods 44. When the two mounting plates 3 move, the support rods 2 can support the two mounting plates 3, and the guide rods 44 can guide the mounting plates 3, so as to improve the stability of the movement of the two mounting plates 3. By adjusting the distance between the two mounting plates 3, the distance between the cutting mechanism 6, the conveying mechanism 7 and the pressing mechanism 8 can be adjusted.

[0028] In embodiment 2, the cutting mechanism 6 includes a DC drive motor 61 installed on the top of the mounting plate 3 and located inside the mounting frame 5. A mounting base 62 is installed on the top of the mounting frame 5. A rotating rod 63 is rotatably connected inside the mounting base 62 via a bearing. A transmission belt 64 is provided between the rotating rod 63 and the output shaft of the DC drive motor 61. A cutting saw blade 65 is installed at the end of the rotating rod 63 near the conveying mechanism 7.

[0029] Both the rotating rod 63 and the output shaft of the DC drive motor 61 are equipped with transmission wheels. The transmission belt 64 is connected between the outer sides of the two transmission wheels. When the DC drive motor 61 is started, the output shaft of the DC drive motor 61 will drive the rotating rod 63 to rotate under the transmission action of the transmission wheels and the transmission belt 64. The rotating rod 63 will drive the cutting saw blade 65 to rotate, and the wood can be cut by the cutting saw blade 65.

[0030] In embodiment 3, the conveying mechanism 7 includes two connecting blocks 71 installed on opposite sides of the two mounting frames 5. A chain conveyor 72 is installed between the two connecting blocks 71 on the side away from the mounting frame 5. Multiple evenly distributed pushing blocks 73 are provided on the outer side of the chain conveyor 72 for pushing the timber. Two guide plates 74 are installed on the top of the mounting frame 5, located in front of and behind the cutting saw blade 65 respectively.

[0031] When cutting both ends of the timber, the timber needs to be placed directly on the chain conveyor 72. After starting the chain conveyor 72, the timber can be pushed by the push blocks 73 on the two chain conveyors 72, so that the timber is close to the cutting saw blade 65 and the timber is cut by the cutting saw blade 65. When placing the timber, each timber needs to be placed between adjacent push blocks 73 to ensure the conveying of the timber.

[0032] During cutting, the cut-off material will fall directly onto the top of the guide plate 74. The guide plate 74 can discharge the material, preventing it from remaining on the top of the mounting frame 5.

[0033] In embodiment four, the pressing mechanism 8 includes two L-shaped rods 81 installed on the top of the mounting frame 5. A top plate 82 is provided between the opposite sides of the two L-shaped rods 81. An electric push rod 83 extending to the bottom of the top plate 82 is provided on the top of the top plate 82. A lifting plate 84 is installed on the piston rod of the electric push rod 83. Two limiting rods 85 are installed on the top of the lifting plate 84. The two limiting rods 85 pass upward through the top plate 82 and are slidably connected to it. A pressing plate 87 is provided below the lifting plate 84. Multiple springs 86 are provided between the bottom of the lifting plate 84 and the top of the pressing plate 87. Pressing inclined plates 88 are provided on both the front and back of the pressing plate 87.

[0034] When conveying and cutting timber, the electric push rod 83 is activated first. The piston rod of the electric push rod 83 drives the lifting plate 84 to move up or down. Under the action of multiple springs 86, the lifting plate 84 drives the pressing plate 87 to move up or down, so that the distance between the bottom of the pressing plate 87 and the top of the chain conveyor 72 is slightly less than the height of the timber. At this time, when the timber is pushed by the push block 73, under the action of the pressing inclined plate 88, the timber can enter the bottom of the pressing plate 87 and lift the pressing plate 87, compressing multiple springs 86. Under the action of the rebound force of multiple springs 86, the pressing plate 87 can stably abut against the top of the timber, thereby achieving the purpose of stable pressing of the top of the timber, which can effectively prevent the timber from vibrating and shifting, and ensure that the cut is flat and smooth.

[0035] The bottom of the pressing plate 87 is smooth, which reduces the friction between the bottom of the pressing plate 87 and the top of the wood, ensuring that the wood can move stably while also ensuring that the pressing plate 87 can press the wood stably, thus ensuring the stability of the wood during cutting.

[0036] In addition, both pressing plates 87 are located between the two chain conveyors 72 on opposite sides, ensuring that the pressing plates 87 can stably press the timber and avoid the pressing plates 87 and the push block 73 from being restricted.

[0037] In Example 5, a PCL controller is provided on the outer side of the support plate 1. The servo drive motor 41, DC drive motor 61, chain conveyor 72 and electric push rod 83 are all electrically connected to the PCL controller. The PCL controller can control the servo drive motor 41, DC drive motor 61, chain conveyor 72 and electric push rod 83.

[0038] It should be noted that the two DC drive motors 61, the two chain conveyors 72, and the two electric push rods 83 are all electrically connected to the PCL controller in parallel to ensure that the two DC drive motors 61, the two chain conveyors 72, and the two electric push rods 83 can start and stop synchronously and have the same range of motion.

[0039] Working principle: The timber is cut using a double-ended saw. In use, first, based on the required cutting length, the servo drive motor 41 is started via the PCL controller to adjust the distance between the two mounting frames 5. Then, the electric push rod 83 is activated, causing the pressing plate 87 to move downwards until the distance between the bottom of the pressing plate 87 and the top of the chain conveyor 72 is slightly less than the height of the timber. Next, the two chain conveyors 72 and two DC drive motors 61 are started. The long timber is placed on the two chain conveyors 72, with both ends of the timber positioned between two adjacent push blocks 73. The chain conveyors 72 operate synchronously, using the push blocks 73 to move the timber towards... In the cutting area conveyor, when the timber moves to the pressing ramp 88, the pressing ramp 88 allows the timber to enter the bottom of the pressing plate 87, lifting the pressing plate 87 and compressing multiple springs 86. Under the rebound force of the multiple springs 86, the pressing plate 87 can stably abut against the top of the timber, so that the pressing plate 87 firmly presses the timber onto the conveying surface of the chain conveyor 72. Subsequently, the timber continues to move, and the cutting saw blade 65 rotates at high speed to cut both ends of the timber synchronously. The cut tail material will fall directly onto the top of the guide ramp 74, through which the tail material can be discharged.

[0040] 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.
