Description

Technical Field

[0001] This invention relates to the field of circular saw technology, specifically to an automatic feeding and jam-proof circular saw for bamboo. Background Technology

[0002] In the bamboo and wood processing process, the circular saw is the basic equipment for cutting and slitting boards. However, when cutting bamboo boards made of bamboo strips or bamboo pieces glued together, due to the inherent physical properties of the material, the traditional circular saw has significant defects in practical applications, which seriously affect processing efficiency, finished product quality and operational safety.

[0003] Bamboo itself has significant inhomogeneity; the density and hardness of the bamboo nodes are much higher than those of the bamboo flesh. This causes the saw blade to encounter periodic and non-linear resistance abrupt changes during the cutting of bamboo and wood panels. Traditional feeding systems, whether manually pushed or driven by a constant-speed motor-screw or hydraulic cylinder, are all rigid feeds. When the saw blade encounters hard bamboo nodes, the huge instantaneous cutting resistance is directly transmitted to the entire transmission chain, causing the saw blade speed to drop sharply or even stop completely, resulting in jamming. This not only damages the saw blade and chipps the edges of the workpiece, producing waste, but may also cause serious personal safety accidents due to the accidental flying of materials or debris. To address this, we propose an automatic feeding, jamming-proof circular bamboo saw. Summary of the Invention

[0007] Preferably, the pushing buffer mechanism includes a hydraulic cylinder, a connecting frame, and a connecting box. The two cutting tables are respectively fixedly installed at both ends of the connecting frame. The worktable has a moving groove, and the connecting frame moves through the moving groove. An L-shaped support plate is fixedly installed at the bottom of the worktable near the other side. The hydraulic cylinder is fixedly installed on the inner wall of the L-shaped support plate. The piston rod of the hydraulic cylinder moves through one side of the L-shaped support plate. The connecting box is fixedly installed at one end of the piston rod of the hydraulic cylinder.

By setting the short inclined surface and the lubrication plate, after the bamboo board is cut, the connecting slide plate can easily make the conical abutment plate slide relative to each other under the reset force of the spring and the damper, reducing the friction between the conical abutment plate and the connecting slide plate, so that the connecting slide plate can automatically reset.

[0013] Preferably, a main synchronous pulley 2 is fixedly installed at one end of the rotating shaft 1, and a driven synchronous pulley 2 is fixedly installed at one end of the rotating shaft 2. A synchronous belt 2 is sleeved on the outer wall of the main synchronous pulley 2 and the driven synchronous pulley 2. A baffle is provided on one side of the cutting saw blade. The baffle is fixedly installed at the bottom of the workbench. By setting the baffle, the motor can be protected to a certain extent.

[0014] Preferably, the fixing component includes a second fixing frame, which is fixedly installed on the top of the cutting table. A second hydraulic cylinder is fixedly installed on the top of the second fixing frame. The piston rod of the second hydraulic cylinder moves through the top of the second fixing frame, and a second pressure plate is fixedly installed at the bottom of the piston rod of the second hydraulic cylinder. The second pressure plate is slidably connected to the inner wall of the second fixing frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through a push-buffer mechanism, achieves fully mechanical adaptive feeding and overload protection. When the saw blade encounters hard points such as bamboo nodes on bamboo or wooden boards, causing a sudden increase in cutting resistance, the inclined friction pair between the connecting slide plate and the conical stop plate will slide relative to each other. This sliding process forces the conical stop plate compression spring to move down, and drives the connecting slide plate compression spring to activate the damper to move back. This converts the sudden resistance into the potential energy and heat energy consumption of the mechanical components, rather than directly impacting the saw blade spindle. This automatically and quickly slows down or even pauses the feed speed, providing valuable grinding time for the high-speed rotating saw blade, allowing it to gradually cut off hard parts with a stable cutting force, and avoiding the phenomenon of the saw blade getting stuck.

[0016] 2. This invention, through its anti-clogging mechanism, actively and continuously solves the problem of chip accumulation in the cutting kerf. The feed motion of the cutting table directly drives the rack plate to move linearly through the connecting frame. The rack plate precisely meshes and drives multiple gears to rotate, ultimately causing the stirring plate located in the narrow cutting kerf to rotate synchronously. The stirring plate continuously stirs between the saw blade and the table surface, promptly breaking up and guiding away the newly generated chips, effectively preventing them from accumulating in the limited space and being compacted by subsequent materials. This eliminates the possibility of forming dense wood chip blocks due to poor chip removal and avoids the phenomenon of the chip blocks causing huge squeezing force on the side of the saw blade, which could lead to seizing.

[0017] 3. This invention, through its cleaning mechanism, efficiently maintains the optimal working condition of the saw blade. Utilizing the rotation of the cutting spindle as a power source, a piston-type air pump is driven by a synchronous belt. The periodic high-pressure airflow generated by the air pump is directly sprayed onto the surface of the saw blade and deep into the chip groove through an aligned nozzle. This powerful airflow can thoroughly blow away fine dust, debris, moist resin, and coolant residue adhering to the cutting edge, significantly improving the smoothness of the cut surface, suppressing the tendency to jam caused by increased friction coefficient and chip groove blockage, and extending the service life of the saw blade.

The connecting slide plate 32 is slidably connected to the inner wall of the connecting box 31. Two sets of extrusion components are provided at the bottom of the connecting box 31. A limit rod 47 is fixedly installed on the inner wall of the connecting box 31. The limit rod 47 moves through the connecting slide plate 32. A spring 48 surrounds the outer wall of the limit rod 47. The spring 48 is fixedly installed between one side of the connecting slide plate 32 and the inner wall of the connecting box 31.

[0030] Furthermore, the fixing component includes a fixing frame 2 57, which is fixedly installed on the top of the cutting table 30. A hydraulic cylinder 2 58 is fixedly installed on the top of the fixing frame 2 57. The piston rod of the hydraulic cylinder 2 58 moves through the top of the fixing frame 2 57, and a pressure plate 2 59 is fixedly installed at the bottom of the piston rod of the hydraulic cylinder 2 58. The pressure plate 2 59 is slidably connected to the inner wall of the fixing frame 2 57.

[0031] Working principle: Before the equipment is started, the bamboo and wooden board to be cut is placed horizontally on two synchronously movable cutting tables 30, and is firmly pressed into the fixed frame 57 by the fixed component, namely the pressure plate 59 driven by the hydraulic cylinder 58, to ensure that the workpiece does not shift during the process of pushing. The motor 6 is started, and the power is transmitted to the rotating shaft 7 through the synchronous belt 10, which drives the cutting saw blade 3 to rotate at high speed, preparing for cutting. Subsequently, the main hydraulic cylinder 51 is activated, and its piston rod pushes the connecting box 31 forward at a constant speed toward the cutting saw blade 3. Inside the connecting box 31, the thrust is transmitted through the frictional engagement between the extrusion assembly and the inclined surface of the connecting slide plate 32. Specifically, the bottom of the connecting slide plate 32 is designed with two inclined surfaces, one long and one short. Initially, its long inclined surface is in close contact with the corresponding friction plate 34 on the first conical abutment plate 33. The resulting static friction drives the connecting slide plate 32, the connecting frame 28, and even the entire cutting table 30 and the bamboo board to feed smoothly toward the saw blade and begin normal cutting. When the saw blade cuts into the uniform material part of the bamboo board, the cutting resistance is stable, and the system maintains the above-mentioned constant speed feeding state. Once the saw blade encounters an abnormally hard point such as a bamboo node, the cutting resistance will suddenly increase. This increased resistance will act in the opposite direction on the entire feeding system, attempting to hinder the cutting table 30 from moving forward. At this time, the connecting box 31 still wants to move forward under the push of the hydraulic cylinder 51, while the connecting slide plate 32, due to the huge reverse resistance transmitted from the bamboo board through the cutting table 30, is between itself and the first conical abutment plate 33. The static friction is broken, and the two slide relative to each other. The connecting slide plate 32 presses the conical abutment plate 33 downward along its long inclined surface, forcing the conical abutment plate 33 to move downward against the elastic force of the spring 40. This process consumes some energy and provides an initial buffer stroke. At the same time, the connecting slide plate 32 slides backward (against the feed direction) relative to the connecting box 31, compressing the second spring 48 and activating the damper 49, further absorbing the impact energy, significantly slowing down the feed speed, and even causing a brief feed pause. This buffering mechanism allows the high-speed rotating saw blade to have grinding time, rather than forcibly resisting the hard point, thereby avoiding the saw blade from stopping or jamming due to torque overload. As the hydraulic cylinder 51 continues to apply pressure, the connecting slide plate 32 finally slides away from the first conical abutment plate 33 and continues its buffer stroke under the reaction force of the second spring 48 until its long inclined surface contacts the corresponding inclined surface of the second conical abutment plate 33. At this time, the impact peak has passed, and the system resumes a smooth feed under the friction of the second pressing component until the hard bamboo joint is completely cut off.

[0032] While feeding and buffering, the anti-clogging mechanism operates synchronously. The movement of the connecting frame 28 drives the rack plate 52 on its side to move synchronously. The rack plate 52 drives multiple gears 53 to rotate. The gears 53 drive the stirring plate 55 located in the cutting slit 4 to rotate continuously through the connecting shaft 54. The stirring plate 55 continuously stirs in the narrow space between the saw blade and the cutting slit 4, effectively breaking up and removing any sawdust that may accumulate, preventing the chips from being compacted in the gap to form a dense block, thereby eliminating the risk of secondary clogging caused by poor chip removal. In addition, the multiple chip removal grooves 27 designed on the cutting saw blade 3 body actively throw out the chips in the tooth grooves by centrifugal force during rotation, enhancing the autonomous chip removal capability. The rotational power of the rotating shaft 7 is transmitted to the rotating shaft 15 through the synchronous belt 13, driving the turntable 16 to rotate. The connecting rod 18 on the turntable 16 converts the rotational motion into the linear reciprocating motion of the top rod 20 through the connecting plate 19, driving the piston plate 21 to reciprocate within the piston guide 17. When the piston plate 21 moves upward, the one-way valve 25 opens to draw in air; when it moves downward, the one-way valve 25 closes and the one-way valve 26 opens, spraying compressed air at high speed onto the surface of the cutting saw blade 3 through the nozzle 23. This pulsed airflow can effectively blow away the attached chips on the surface of the saw blade and deep in the chip removal grooves 27, keeping the saw blade teeth clean and sharp, reducing the risk of resin adhesion due to frictional heat, and ensuring smooth cutting from another perspective, preventing jamming.
