Description

Technical Field

[0001] This utility model relates to the field of square timber processing technology, and in particular to a high-efficiency anti-deformation fixed-length cutting device for square timber. Background Technology

[0002] In the field of timber processing, the cutting of square timber to length is a core process in industries such as furniture manufacturing and building structures. Traditional cutting devices generally use a fixed clamping mechanism in conjunction with a circular saw or band saw to complete the operation, but this has significant drawbacks in practical applications: on the one hand, during the cutting process, the high-speed impact of the saw blade and the rigid clamping of the fixture can easily cause the rapid release of internal stress, leading to the twisting and cracking of fibers near the cut; on the other hand, the shrinkage and expansion effects caused by changes in the moisture content of the timber make it difficult for traditional mechanical positioning to guarantee the long-term stability of the finished product dimensions, requiring repeated adjustments and seriously affecting processing efficiency. To address these issues, we propose a high-efficiency, anti-deformation, fixed-length cutting device for square timber. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-efficiency anti-deformation fixed-length cutting device for square timber.

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

[0026] Please see Figure 1-7 This utility model provides a technical solution: It includes a mounting base 100, a control panel 110 on one side of the mounting base 100, a support back plate 120 fixed to the top edge of the mounting base 100 by bolts, a square timber body 130 slidably connected to one side of the support back plate 120, a support mechanism on the side wall of the mounting base 100, and a pressing mechanism on the top of the mounting base 100. The pressing mechanism includes a mounting column 310, a hydraulic rod B320, and a drive plate 330. A pressure sensor B340 is fixed to the bottom of the drive plate 330, and a mounting slide plate 350 is fixed to the bottom of the pressure sensor B340. A mounting slide column 360 is slidably connected to the inner wall of the mounting slide plate 350, a spring 361 is provided on the outer side of the mounting slide column 360, and a connecting bracket 370 is fixed to the bottom of the mounting slide column 360. A pressure roller 380 is rotatably connected to the inner wall of the connecting bracket 370. A driving mechanism is provided on the outer side of the mounting base 100, and a cutting mechanism is provided on the inner wall of the mounting base 100. A preheating mechanism is provided on one side of the cutting mechanism. The square timber is transported by the driving mechanism. During the process, the supporting mechanism provides applicable limiting support to the side of the square timber, the pressure mechanism provides applicable compression to the square timber, and finally the cutting mechanism performs the cutting operation on the square timber. By dynamically adjusting the distribution of the compression force, the deformation caused by the release of internal stress in the wood during the cutting process is offset. Lateral and top coordinating compression prevents lateral displacement and longitudinal vibration of the wood during high-speed cutting, improving the accuracy of fixed-length cutting. During the cutting process, the preheating mechanism locally heats the cutting path to soften the wood fibers and release local stress. Hot air pretreatment reduces the stress mutation at the moment of cutting, reducing the risk of cracking of the square timber.

[0027] Specifically, the support mechanism includes a mounting side plate 210, which is fixed to the side wall of the mounting base 100 by bolts. A hydraulic rod A220 is fixed to one side of the mounting side plate 210, and a pressure sensor A230 is fixed to one end of the hydraulic rod A220. A rotating bracket A240 is fixed to one side of the pressure sensor A230, and a support roller 250 is rotatably connected to the inner wall of the rotating bracket A240. By setting up the support mechanism, during the transportation of square timber, the side of the square timber can be limited and clamped by the cooperation of the support rollers 250 on both sides. During the process, the pressure sensor A230 detects the pressure at the support roller 250 in real time and controls the extension and retraction of the hydraulic rod A220, thereby realizing dynamic limiting and clamping of the side of the square timber and providing side support for the square timber during cutting.

[0028] Specifically, the drive mechanism includes a mounting bracket 410, which is fixed to one side of the mounting base 100 by bolts. A hydraulic rod C420 is fixed to one side of the mounting bracket 410, and a drive bracket 430 is fixed to one end of the hydraulic rod C420. A drive roller 440 is provided on one side of the drive bracket 430. By providing a drive mechanism, the square timber is moved by the rotation of the drive roller 440, which enables the transportation of the square timber.

[0029] Specifically, the cutting mechanism includes a mounting frame 510, which is fixed to the inner wall of the mounting base 100 by bolts. A drive motor 520 is fixed to one side of the mounting frame 510 by bolts. A drive shaft 521 is provided at the output end of the drive motor 520. A drive roller 530 is fixed to the outside of the drive shaft 521. A cutting saw blade 540 is provided to the outside of the drive roller 530. A saw blade limiting block 550 is slidably connected to the outside of the cutting saw blade 540. The saw blade limiting block 550 is fixedly connected to the mounting frame 510. The cutting mechanism is used to cut the square wood.

[0030] Specifically, the preheating mechanism includes a mounting plate 610, which is fixed to one side of the mounting frame 510 by bolts. A hot air blower 620 is fixed to one side of the mounting plate 610, and a hot air nozzle 630 is fixed to one side of the hot air blower 620. By setting up the preheating mechanism, during the cutting operation, hot air is blown out by the hot air blower 620 and blown onto the cutting saw blade 540 through the hot air nozzle 630. This can preheat the cutting saw blade 540 before cutting, locally heat the cutting path, soften the wood fibers to release local stress, and reduce the stress change at the moment of cutting by using hot air pretreatment, thereby reducing the risk of cracking of the square timber.

[0031] Working Principle: During use, the device is controlled via control panel 110. Hydraulic rod C420 moves drive bracket 430, which in turn moves drive roller 440, placing it against one side of the timber. The rotation of drive roller 440 moves the timber, enabling transport. During transport, hydraulic rod A220 moves pressure sensor A230, which in turn presses support roller 250 onto the timber. The support rollers 250 on both sides work together to clamp and limit the sides of the timber. During this process, pressure sensor A230 monitors the pressure on support roller 250 in real time and controls the extension and retraction of hydraulic rod A220, thus achieving dynamic clamping and limiting of the timber's sides. This provides lateral support for the timber during cutting. Hydraulic rod B320 moves drive plate 330 downwards, causing pressure roller 380 to press against the top of the timber. Under the action of spring 361... The lower mounting column 360 slides elastically on the mounting plate 350, allowing the clamping roller 380 to apply appropriate clamping pressure to the square timber. The clamping pressure is detected in real time by the pressure sensor B340, and the extension and retraction of the hydraulic rod B320 are controlled to dynamically adjust the clamping force to adapt to the irregular top surface of the square timber. The drive motor 520 drives the drive shaft 521 to rotate, and the drive roller 530 rotates, which in turn drives the cutting saw blade 540 to rotate. The saw blade limiting block 550 provides limiting support for the cutting saw blade 540, and the cutting saw blade 540 performs the cutting operation on the square timber. During the cutting operation, the hot air blown by the hot air fan 620 blows hot air through the hot air nozzle 630 onto the cutting saw blade 540, which can preheat the cutting saw blade 540 before cutting, locally heat the cutting path, soften the wood fibers to release local stress, and reduce the stress change at the moment of cutting by using hot air pretreatment.

Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and accompanying drawings.
