Description

Technical Field

[0001] This invention relates to the field of wood processing technology, and in particular to a transverse cutting and sawing production line capable of optimizing wood batching and precise cutting. Background Technology

[0002] When producing furniture, doors, windows, and flooring, it is necessary to identify defects such as knots and cracks in the wood and classify them according to characteristics such as texture and color. However, due to differences in the actual grade of wood, inconsistent raw material quality, limitations of manual material preparation, and unreasonable sawing schemes, problems such as low wood utilization rate, high production costs, and serious waste occur in the material preparation section. The optimal cutting saw can reasonably optimize the material preparation scheme, achieve maximum sawing yield, and higher production efficiency.

[0003] The optimized cutting production line is controlled by a computer system, with all components coordinating and cooperating for automated processing, forming an assembly line operation. The applicant's patent application (200610039230.4), filed on March 31, 2006, and authorized for a wood optimization cutting method and its optimized cutting saw, discloses such a transverse optimization saw machine (production line). The transverse optimization cutting production line consists of, from right to left, a wood conveyor, a wood photoelectric scanning detection device, a sawing machine, a waste removal machine, a finished product sorting machine, and a computer controller and interactive interface. During processing, the wood to be processed enters from the right side, undergoing a series of processes including photoelectric scanning, sawing, waste removal, and finished product sorting to remove waste and classify the finished wood according to its length and grade. While this wood cutting production line effectively achieves optimized wood cutting and improves sawing yield, after a considerable period of actual operation, the existing optimized cutting production line has shown some shortcomings in cutting speed, processing accuracy, and intelligent control adaptability.

[0004] Firstly, the timber conveying and scanning detection device includes a feed conveyor belt and a length measuring wheel connected to the encoder. Currently, the timber is fed by friction with the conveyor belt, leaving it in an unconstrained, free state. This results in several issues: firstly, the smoothness of the timber's path and speed cannot be controlled, leading to increased errors in length measurement and positioning accuracy, as well as inaccurate defect scanning; secondly, this unconstrained free movement of the conveyor belt significantly limits further improvements in feeding speed and sawing efficiency, with most feed conveyor belts currently limited to a feeding speed of around 200 meters per minute, making further increases difficult. The length measuring wheel connected to the encoder measures length by its own weight pressing against the timber. Since the surface of the timber is not perfectly flat, the measuring wheel may bounce and momentarily detach from the surface during measurement, causing deviations in the length measurement data. Especially when the feeding speed increases, the measuring wheel may also reverse, causing the length data to change towards negative values, further increasing the deviation. Currently, the height adjustment of the feeding pressure roller and the measuring roller relies on manual adjustment. This manual adjustment is not only inefficient and inaccurate, but also cannot meet the needs of intelligent adjustment and control of automated production lines, thus limiting the operating efficiency of the entire production line.

[0005] The sawing machine is a key component of the optimal cross-cutting saw. Its swing cutting speed not only determines the sawing efficiency of the production line but also directly affects the sawing accuracy. As the operating efficiency of the cross-cutting saw production line increases, the swing cutting frequency of the circular saw blade increases significantly, especially at the two endpoints of the swing arm's swing, where the swing speed changes drastically and the impact force is large. This intensifies the swing cutting vibration and impact of the saw blade. This increased vibration and impact frequency not only leads to a decrease in wood sawing accuracy and quality but also increases the likelihood of sawing machine malfunctions and even safety issues. Currently, the swing cutting amplitude of the circular saw blade is fixed. Regardless of the thickness of the wood being cut, the circular saw blade operates at a fixed swing cutting amplitude. When the wood to be sawed is thin, there is actually a large useless swing angle in the circular saw blade's swing arm. When the feed speed of the cross-cutting saw production line increases significantly, this useless swing angle will significantly occupy the wood cutting time, limiting further increases in feed speed. At the same time, the increased speed of wood conveying will also exacerbate the jumping of the upper pressure roller, increasing both its jumping frequency and amplitude. During the pushing process, the upper pressure roller will separate from the wood, causing the wood to lose its clamping and pushing effect instantly. This directly affects the deviation of the actual sawing length of the wood and the decline in sawing quality, becoming an obstacle to improving the efficiency of the production line.

[0006] The preferred waste removal device for a saw includes a finished product conveyor belt and a waste separation and removal opening formed by the extension and retraction of the finished product conveyor belt. In the existing structure, the extension and retraction drive of the finished product conveyor belt is implemented by a cylinder. When sawing finished wood, the finished wood is pushed from the sawing table onto the conveyor belt by the cylinder, and then sent to the wood sorting process. When sawing waste, the conveyor belt retracts under the action of the cylinder to form a removal opening, and the waste falls into the waste bin. However, in this structure, the drive device for the conveyor belt is a cylinder, and the operation of the cylinder requires an additional electromagnetic control valve. In addition, the response speed and position control accuracy of the cylinder itself are not high. Therefore, the response speed of the existing waste removal device is slow. With the significant increase in the material feeding speed of the sawing production line, the cylinder extension and retraction drive device can no longer meet the response requirements for rapid waste removal, thus becoming a bottleneck restricting the improvement of the overall production line operating efficiency.

[0007] Based on the input parameter list for sawn timber, as the sawn timber passes through the sorting conveyor belt, the computer control system automatically controls each pushing station to automatically push finished materials of different specifications and grades to designated storage positions or designated conveyor belts for output. Currently, there are several pushing stations distributed along the length of the sorting conveyor belt. Each pushing station includes a pushing cylinder. When the cylinder and piston extend, they push the corresponding specification of finished material away from the sorting conveyor belt. After pushing is completed, the cylinder piston rod retracts to prepare for the next cycle of pushing. Obviously, the piston extending outward is a working stroke, while the piston retracting is an idle stroke. When the piston is in the idle stroke state, and there happens to be a corresponding finished material that needs to be pushed away, the sorting conveyor belt can only pause and wait. This will obviously affect the operating efficiency of the production line, especially when the sorting conveyor belt needs to run at high speed. This sorting and pushing structure will become a limiting factor for improving operating efficiency. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide a transversely optimized cutter saw production line that can not only effectively improve the cutting speed of the cutter saw, but also effectively ensure the cutting accuracy.

[0009] To solve the above-mentioned technical problems, the present invention provides a transverse preferred sawing production line, including a feeder, a sawing machine, a waste removal machine and a finished product sorting machine. The feeder, sawing machine, waste removal machine and finished product sorting machine are arranged in sequence from front to back along the wood sawing path. A wood detector is installed above the feeder.

[0010] The conveyor includes a conveyor frame, and frame side plates and guide side plates mounted on the conveyor frame. A conveyor belt is provided between the parallel frame side plates and guide side plates. A side pressure roller that can press against the guide side plate is elastically supported on the frame side plate. A lower pressure roller is installed on one side of the guide side plate and presses against the conveyor belt.

[0011] The length measuring wheel of the timber detector is movably mounted above the conveyor belt; the length measuring wheel is rotatably supported on a length measuring wheel swing arm, which is hinged to a sliding bracket. A length measuring wheel cylinder is also hinged to the length measuring wheel swing arm; the sliding bracket is slidably supported on the detector bracket via a sliding guide rod; a slide carriage motor mounted on the detector bracket drives the slide carriage through a slide carriage screw pair; an angle sensor is mounted on the upper end of the screw of the slide carriage screw pair; the length measuring wheel is connected to a length measuring encoder via a coupling.

[0012] The sawing machine includes a sawing frame, a circular saw blade, and a lower support roller rotatably supported on the worktable of the sawing frame. An upper pressure roller is also rotatably supported above the lower support roller. The circular saw blade is located between two adjacent upper pressure rollers and is rotatably supported on the extended end of a circular saw blade swing arm. The other end of the circular saw blade swing arm is hinged to the sawing frame. The extended end of the circular saw blade swing arm is hinged to a connecting rod via a buffer hinge. The other end of the connecting rod is hinged to a swing crank. The swing crank is fixedly mounted on the output shaft of the swing motor via an eccentric block.

[0013] The waste removal machine includes a removal machine frame, a removal machine fixed cover fixedly installed on the removal machine frame, and a sliding cover slidably installed on the removal machine frame; two sliding cover drive pulleys rotatably installed on the removal machine fixed cover are tensioned with sliding cover drive belts, and the sliding cover drive belts reciprocate to drive the sliding covers; a fixed pulley is rotatably supported on the removal machine fixed cover, and a sliding cover pulley one and a sliding cover pulley two are rotatably supported on the sliding cover; the finished product conveyor belt is sequentially wound around the sliding cover pulley two, the sliding cover pulley one, and the fixed pulley;

[0014] The sorting frame of the finished product sorting machine is tensioned with a sorting conveyor belt. A sorting guide side plate and several pusher groups are provided on one side of the sorting frame. Each pusher group includes two adjacent pusher cylinders. Each pusher cylinder is connected to the air source through a cylinder control valve.

[0015] Furthermore, the side pressure roller is mounted on the side plate of the frame via a material conveying side pressure device; the lower pressure roller is mounted on the material conveying frame via a material conveying lower pressure device; both the material conveying side pressure device and the material conveying lower pressure device are tensioning buffer devices.

[0016] Furthermore, the cylinder body of the measuring wheel cylinder is hinged on the sliding bracket, and the piston rod of the measuring wheel cylinder is hinged to the measuring wheel swing arm; the sliding bracket is also supported by an auxiliary pressure roller through an auxiliary roller support, which is a tensioning buffer device.

[0017] Furthermore, the measuring wheel is movably mounted on the one-way clutch spindle, and clutch rollers are movably arranged in the wedge-shaped cavity of the spindle formed by the measuring wheel and the one-way clutch spindle. The one-way clutch spindle is supported on the measuring wheel swing arm.

[0018] Furthermore, the mandrel wedge cavity is provided with at least two clutch rollers, each clutch roller having a different diameter; the measuring wheel and the one-way clutch mandrel form four mandrel wedge cavities.

[0019] Furthermore, the upper pressure roller is rotatably supported on the pressure roller slide, which is fixedly installed on the piston rod end of the pressure cylinder. The pressure roller slide is movably supported on the pressure roller fixed seat through the slide guide rod. A guide rod top baffle is fixedly installed at the extended top of the slide guide rod. An elastic buffer pad is fitted on the slide guide rod between the guide rod top baffle and the pressure roller fixed seat. The elastic buffer pad is a rubber elastic pad.

[0020] Furthermore, the buffer hinge includes a hinge housing, which is movably fitted onto the swing sleeve. A winged buffer sleeve is provided in the cavity of the swing sleeve, with the wing of the winged buffer sleeve extending into the recess of the swing sleeve. The winged buffer sleeve is fixedly installed on the hinge support shaft. Buffer elastic blocks are provided on both sides of the wing of the winged buffer sleeve extending into the recess of the swing sleeve.

[0021] Furthermore, four winglets are symmetrically arranged on the outer side of the winged buffer sleeve, each winglet extending into the corresponding cavity of the swing sleeve; the buffer elastic block is a rubber elastic pad; the hinge support shaft is fixedly installed on the extended end of the circular saw blade swing arm, and a connecting rod is fixedly screwed onto the hinge housing; the connecting rod is hinged to the crank hinge support shaft, which is fixedly installed on the swing cutting crank, and the crank hinge support shaft and the motor output shaft are spaced apart.

[0022] Furthermore, an eccentric block is fixedly installed on the motor output shaft of the swing-cutting motor, and the eccentric block is fixedly connected to the swing-cutting crank through a locking cone sleeve.

[0023] Furthermore, the locking cone sleeve is a conical sleeve with an open groove, the cone angle β of which is 3°-5°, and one end of the conical sleeve is provided with a thread for screwing a nut; the locking cone sleeve is installed in the conical hole of the oscillating crank.

[0024] Furthermore, the sliding cover drag pulley and the sliding cover drag belt form a synchronous toothed belt transmission pair, and one side of the sliding cover drag belt is fixedly locked to the sliding cover; a telescopic drive motor is fixedly installed on the material rejecting machine fixed cover, and the telescopic drive motor drives the sliding cover drag pulley.

[0025] Furthermore, the two adjacent pusher cylinders of the pusher assembly are mounted on the sorting frame via the same cylinder mounting base; the cylinder control valve is a two-position five-way double-electric control directional valve, and the pusher cylinder is a double-acting cylinder.

[0026] In the above structure, since the side plate of the conveyor frame is elastically supported by a side pressure roller that presses against the conveyor guide plate, the side pressure roller and the conveyor guide plate form a horizontal clamping of the wood to be sawed, so that the wood can only move forward along the guide path of the guide plate, avoiding the wood from swinging on the horizontal conveying surface; at the same time, a lower pressure roller is installed on one side of the conveyor guide plate, which presses the wood against the conveyor belt, ensuring the synchronous operation of the wood and the conveyor belt, and avoiding slippage such as the wood being ahead or behind on the conveying surface, thus ensuring high length measurement accuracy and position accuracy. Even when the conveyor belt is running at high speed, it can still maintain high-speed and high-precision detection of the wood position and quality.

[0027] Furthermore, because the measuring wheel is movably mounted on a one-way clutch mandrel, and the wedge-shaped cavity formed by the measuring wheel and the one-way clutch mandrel contains a clutch roller, the measuring wheel, clutch mandrel, and roller constitute a one-way locking structure. This ensures that the measuring wheel can only rotate in one direction relative to the mandrel and cannot rotate in the opposite direction. Even if the measuring wheel bounces during operation, it will not rotate in the opposite direction, thus preventing measurement errors. This makes it more suitable for accurate measurement of wood at high speeds. A measuring wheel cylinder is hinged to the measuring arm, and the measuring wheel cylinder... The long swing arm applies pressure to the measuring wheel, ensuring that the measuring wheel is in close contact with the wood to be sawed on the conveyor belt. This generates sufficient friction between the wood and the conveyor belt to ensure synchronous operation of the wood and the conveyor belt, while also ensuring close contact between the measuring wheel and the wood to guarantee measurement accuracy. The sliding bracket for mounting the measuring wheel is slidably supported on the detection bracket by a guide rod. The sliding motor drives the sliding bracket through a lead screw pair to adjust the height of the measuring wheel. This not only improves the accuracy of adjusting the height of the measuring wheel but also enables automated control.

[0028] Because the circular saw blade support arm, swing linkage, and swing-cutting crank constitute a crank-connecting rod mechanism, the circular saw blade can continuously reciprocate saw the wood as the circular saw blade arm swings up and down. This results in high work efficiency, simple structure, and easy maintenance and repair. The extended end of the circular saw blade support arm is connected to the swing-cutting linkage via a buffer hinge. This buffer hinge not only creates a hinged relationship between the circular saw blade arm and the swing-cutting linkage, but more importantly, its buffering and vibration isolation effect effectively reduces or even significantly reduces the adverse effects of the reciprocating swing of the arm on the circular saw blade. This avoids the widening of the kerf and the roughness of the saw surface caused by the circular saw blade sway due to system vibration, thus preventing a decrease in sawing accuracy and quality. It is also more conducive to the high-speed operation of the sawing production line. This vibration reduction and isolation structure also reduces the vibration of the sawing machine, improves the stability of the sawing machine's operation, avoids damage to moving parts, and extends the service life. Meanwhile, the swing crank is fixedly mounted on the output shaft of the swing motor via an eccentric block. By adjusting the mounting angle of the eccentric block on the motor shaft, the actual length of the swing crank can be changed. In turn, the swing amplitude of the circular saw blade arm can be changed according to the thickness of the wood being sawn, reducing ineffective swing angles and improving the efficiency of the saw cutter.

[0029] Because the sliding cover drag belt is tensioned on the two sliding cover drag pulleys of the fixed cover of the chipper, the drag pulley and the drag belt form a reciprocating drag pair. The drive motor drives the sliding cover to extend and retract relative to the fixed cover through the reciprocating drag pair, so as to close or open the waste removal port. It is not only simple in structure, easy to manufacture and maintain, but also has a faster response speed, which is conducive to the rapid separation of waste and improves the operating efficiency of the saw.

[0030] Because several pusher groups are installed on the side of the sorting conveyor belt, the pusher groups can push finished wood of different specifications and grades to the corresponding positions, realizing automatic sorting of finished wood. The pusher group includes two adjacent pusher cylinders. On the one hand, the two cylinders can push the material alternately. That is, when the piston of one cylinder extends to push the material, the piston of the other cylinder retracts to prepare to push the material, thus adapting to the needs of the high-speed operation of the sorting conveyor belt. On the other hand, when the length of the finished wood is long, the pushing force of a single pusher cylinder is insufficient. The synchronous pushing of the two cylinders can improve the reliability of the separate pushing.

[0031] The technical solution of the present invention can effectively ensure the accuracy of wood cutting while achieving a cutting speed of 400 meters per minute, which is far superior to the existing technology. Attached Figure Description

Detailed Implementation

[0062] like Figure 1 The horizontally optimized sawing production line shown includes, from right to left, a stacking platform 1, a conveyor 2, a sawing machine 4, a waste removal machine 5, and a finished product sorting machine 6. A timber detector 3 is located above the conveyor 2. The optimized sawing machine also includes a computer control system and a human-machine interface platform. The timber to be processed enters the processing flow from the stacking platform 1 on the right, undergoing a series of processes including photoelectric scanning detection, sawing, waste removal, and sorting to complete the processing task. The timber is conveyed and processed sequentially along the above processing path, ultimately being sorted into finished timber of different specifications and grades. The operator pre-inputs the required length and quality parameters into the control computer, and uses a fluorescent pen to mark the defect locations and grade conversion points on the board to be sawed on the stacking platform 1. Then the board passes through a detector equipped with an encoder, which measures the length of the board and the marked points, and transmits this information to the computer. The computer then processes this information and sends it to each execution component, which saws the board according to the preferred instructions. After sawing, the waste is removed by a waste removal machine, and the finished product sorting machine classifies the wood according to its length and grade.

[0063] like Figure 2 As shown, the function of conveyor 2 is to transport marked and inspected timber to the sawing machine for cutting. Conveyor 2 includes a conveyor frame 201, with two conveyor pulleys 212 rotatably supported at its front and rear ends. The conveyor pulley 212 at the rear end of the conveyor frame 201 is connected to a conveyor belt motor 213 via a conveyor belt drive pair 211. A conveyor belt 202 is tensioned on the two conveyor pulleys 212. The conveyor belt drive pair 211 is a synchronous toothed belt drive pair, the conveyor belt motor 213 is a servo motor, and the conveyor belt 202 is a flat conveyor belt.

[0064] A conveyor frame side plate 214 is fixedly installed on one side of the conveyor frame 201, and a conveyor guide side plate 203 is fixedly installed on the other side. The conveyor belt 202 is located between the parallel conveyor frame side plate 214 and the conveyor guide side plate 203. A side pressure roller 207 is elastically supported on the conveyor frame side plate 214, which can press against the conveyor guide side plate 203. A lower pressure roller 210 is installed on the conveyor frame 201 on one side of the conveyor guide side plate 203. The lower pressure roller 210 is located above the conveyor belt 202 and can press the wood against the conveyor belt 202.

[0065] like Figure 3As shown, the side pressure roller 207 is rotatably supported on the extended end of the side pressure roller support arm 206. A rubber sleeve is fitted onto the surface of the side pressure roller 207. The other end of the side pressure roller support arm 206 is fixedly connected to the conveying side pressure device 205. The conveying side pressure device 205 is fixedly mounted on the side pressure device mounting base 204 with an adjustable installation angle. The side pressure device mounting base 204 is fixedly mounted on the side plate 214 of the conveyor frame. The conveying side pressure device 205 is a commonly used tensioning and buffering device in mechanical engineering.

[0066] like Figure 4 As shown, the pressure roller 210 is adjustablely fixedly mounted on the pressure roller mounting base 209 via the material conveying pressure roller 208, and the pressure roller mounting base 209 is fixedly mounted on the material conveyor frame 201. The material conveying pressure roller 208 is also a commonly used tensioning and buffering device.

[0067] like Figure 5 , Figure 6 and Figure 7 As shown, the detector bracket 301 of the timber detector 3 is fixedly connected to the conveyor frame 201, so that the measuring wheel 313 and auxiliary pressure wheel 302 of the timber detector 3 are located above the conveyor belt 202 of the conveyor 2. Two parallel sliding guide rods 309 are fixed on the detector bracket 301, and the sliding bracket 304 is slidably supported on the detector bracket 301 by sliding up and down through the two sliding guide rods 309. A sliding motor 305 is also fixedly installed on the top of the detector bracket 301. The sliding motor 305 drives the lead screw of the sliding lead screw pair 308 through the lead screw reducer 306, and the nut of the sliding lead screw pair 308 is installed on the sliding bracket 304. When the carriage motor 305 rotates in the forward or reverse direction, it drives the sliding bracket 304 to move up and down along the carriage guide rod 309 via the carriage screw pair 308, thereby changing the height of the measuring wheel 313 and the auxiliary pressure wheel 302 to adapt to the inspection requirements of wood of different thicknesses. The carriage motor 305 is a servo motor.

[0068] The lead screw of the carriage lead screw pair 308 extends out of the upper cover of the lead screw reducer 306 and is fixedly connected to the toothed indexing plate of the angle sensor 307. For example... Figure 8 The angle sensor 307 shown includes an adjacent toothed indexing plate and a commonly used proximity switch. The proximity switch is fixedly mounted on the lead screw reducer. Six sensing teeth are evenly distributed on the surface of the toothed indexing plate. Depending on the detection accuracy, the plate can also be designed with more than six sensing teeth. The proximity switch can be an inductive, capacitive, or Hall effect type, etc. The proximity switch rotates synchronously with the lead screw of the carriage lead screw 308.

[0069] Two measuring rollers 313 and an auxiliary pressure roller 302 are hinged at a distance from each other on the sliding bracket 304. A corresponding coupling seat 316 is fixedly mounted on the back of each measuring roller 313. A coupling 317 is connected to this coupling seat 316, and the other end of the coupling 317 is connected to a length encoder 318, which is mounted on the sliding bracket 304. The coupling 317 is a universal coupling, and the length encoder 318 is an optical, magnetic, or electrical encoder.

[0070] A position sensor 314 and a quality sensor 315 are also mounted on the sliding bracket 304, located between the two measuring wheels 313. The position sensor 314 is a proximity sensor, while the quality sensor 315 is a photoelectric scanning head.

[0071] like Figure 9 , Figure 10 and Figure 11 As shown, a coupling seat 316 is fixedly installed on one end face of the measuring wheel 313, and a mandrel mounting blind hole is provided on the other end face of the measuring wheel 313. A one-way centrifugal mandrel 319 is movably arranged in the mandrel mounting blind hole, that is, the measuring wheel 313 is fitted on the one-way clutch mandrel 319. Four grooves are evenly distributed on the one-way clutch mandrel 319, which together with the inner wall of the blind hole on the measuring wheel 313 form four mandrel wedge cavities 321. Three clutch rollers 320 are movably arranged in each mandrel wedge cavity 321. The diameter of each clutch 320 decreases sequentially. This not only helps to improve the concentricity of the mandrel and the measuring wheel, but also enhances the wedging ability. A one-way clutch spindle 319 is fixedly installed at the extended end of the measuring wheel swing arm 312. The other end of the measuring wheel swing arm 312 is pivotally hinged to the sliding bracket 304. A measuring wheel cylinder 310 is also hinged to the measuring wheel swing arm 312. The piston rod of the measuring wheel cylinder 310 is hinged to the measuring wheel swing arm 312. The cylinder body of the measuring wheel cylinder 310 is installed on the swing arm hinge support.

[0072] like Figure 12 As shown, the auxiliary pressure roller 302 is rotatably mounted on the auxiliary roller support 303, which is mounted on the sliding bracket 304. The auxiliary roller support 303 is a tensioning buffer device.

[0073] like Figure 13As shown, the sawing frame 401 of the sawing machine 4 and the scrap removal machine frame 501 of the scrap removal machine 5 are installed adjacent to each other and fixedly, and the worktable of the sawing machine 4 and the conveyor belt of the scrap removal machine 5 are on the same horizontal plane. A fixed mounting wall plate 410 is fixedly installed on the sawing frame 401. The fixed mounting wall plate 410 movably supports three upper pressure rollers 403 and one measuring roller 413 from front to back. The circular saw blade 414 is located between two adjacent upper pressure rollers 403 at the rear, and the measuring roller 413 is located between two adjacent upper pressure rollers 403 at the front. Several lower support rollers 402 are rotatably supported on the worktable of the sawing frame 401. The upper pressure rollers 403 are rotatably supported above the lower support rollers 402. A front nozzle 412 is provided on the front side of the circular saw blade 414. The front nozzle 412 is fixedly installed on the fixed mounting wall plate 410. A saw blade cover 411 is also covered on the circular saw blade 414. The saw blade cover 411 is also installed on the fixed mounting wall plate 410. A discharge baffle 416 is also installed on the fixed mounting wall plate 410.

[0074] A scraper fixing cover 502 is fixedly installed on the scraper frame 501. A sliding cover 505 that can slide horizontally back and forth is also installed on the scraper frame 501. The waste nozzle 415 is located at the front end of the sliding cover 505.

[0075] like Figure 14 , Figure 15 As shown, two sliding cover drive pulleys 503 are rotatably supported on the fixed cover 502 of the scraper. A sliding cover drive belt 509 is tensioned on these two sliding cover drive pulleys 503. The two sliding cover drive pulleys 503 and the sliding cover drive belt 509 constitute a synchronous toothed belt drive pair. A fixed pulley 513 is also rotatably supported on the fixed cover 502 of the scraper, and the fixed pulley 513 is located approximately at the retracted end position of the sliding cover 505. A first sliding cover pulley 512 and a second sliding cover pulley 514 are rotatably supported on the sliding cover 505, and the second sliding cover pulley 514 is rotatably supported at the front end of the sliding cover 505. The sliding cover 505 is fixed to one side of the sliding cover drive belt 509 by a drive belt locking block 510. The sliding cover drag pulley 503, located at the front end of the scraper fixed cover 502, is the driving pulley. A telescopic drive motor 507 is fixedly installed on the scraper fixed cover 502. The telescopic drive motor 507 drives the sliding cover drag pulley 503, which is the driving pulley, through the drag wheel reducer 506. The telescopic drive motor 507 is a servo motor. When the telescopic drive motor 507 rotates in the forward or reverse direction, the sliding cover drag belt 509, which is tensioned on the sliding cover drag pulley 503, reciprocates to drag the sliding cover 505, thereby opening or closing the material discharge port used for scrap removal.

[0076] The finished product conveyor belt 508 sequentially passes over the sliding cover pulley 2 514, the sliding cover pulley 1 512, and the fixed pulley 513. When the telescopic drive motor 507 drags the sliding cover 505 back via the sliding cover drag belt 509, the sliding cover pulley 2 514 and the sliding cover pulley 1 512 on the sliding cover 505 move backward, while the fixed pulley 513 remains in a different position, thus ensuring that the length of the finished product conveyor belt 508 remains unchanged, and vice versa.

[0077] When the sliding cover 505 retracts and opens the waste discharge port, the waste blowing nozzle 415 located in front of the sliding cover 505 blows the waste off. The nozzle 412 on the front side of the saw blade can assist in pushing the wood towards the sawing edge of the circular saw blade 419, especially for the wood tail, which has a significant blowing and pushing effect; because the tail is relatively short at this time, the lower roller and the upper pressure roller 403 have difficulty forming an effective clamping and pushing effect on the short tail.

[0078] like Figure 16 , Figure 17 As shown, three pressure roller fixing seats 405 are all fixedly installed on the fixing seat mounting wall plate 410. Each pressure roller fixing seat 405 has an "H"-shaped structure, and the cylinder body of the pressure roller cylinder 406 is fixedly installed in the middle position of the pressure roller fixing seat 405. Guide rod holes for movable mounting slide guide rods 407 are provided on both sides of the pressure roller fixing seat 405. The piston rod end of the pressure roller cylinder 406 is fixedly connected to the pressure roller slide 404, and the upper pressure roller 403 is rotatably mounted on the pressure roller slide 404. Two slide guide rods 407 are vertically fixed on both sides of the pressure roller slide 404. The slide guide rods 407 extend upward through two guide rod holes on the pressure roller fixing seat 405. A guide rod top baffle 408 is fixedly installed at the extended top of the slide guide rod 407. An elastic buffer pad 409 is fitted on the slide guide rod 407 between the guide rod top baffle 408 and the top surface of the pressure roller fixing seat 405. The elastic buffer pad 409 is a ring-shaped rubber elastic washer. The elastic buffer 409 can also be a cylindrical helical spring. Because the wood to be sawed, held between the lower roller 402 and the upper pressure roller 403, has an uneven surface and a large degree of curvature, the upper pressure roller 403 will have a large amount of runout during actual operation. The elastic buffer pad 409 not only effectively buffers and reduces the runout amplitude of the upper pressure roller 403, but also limits the runout amplitude to a reasonable range, avoiding the impact of excessive runout amplitude and vibration of the upper pressure roller 403 on the sawing dimension accuracy.

[0079] A measuring wheel 413 is also movably mounted on the wall panel 410 of the fixed base. The mounting structure of the measuring wheel 413 is the same as that commonly found in existing preferred saws.

[0080] like Figure 18 , Figure 19As shown, the circular saw blade 414 is located between two adjacent upper pressure rollers 403. The circular saw blade 414 is rotatably supported on the front end of the circular saw blade swing arm 420 via a saw blade shaft. The other end of the saw blade shaft is connected to the saw blade motor 417 via a saw blade belt drive pair 418, which is a synchronous toothed belt drive pair. The saw blade motor 417 is mounted on a motor mounting base 419. The rear end of the circular saw blade swing arm 420 is hinged to the motor mounting base 419 via a swing arm pin. The motor mounting base 419 is fixedly mounted on the sawing machine frame 401.

[0081] A connecting rod 422 is hinged to the front end of the circular saw blade swing arm 420 via a buffer hinge 421. The other end of the connecting rod 422 is hinged to the swing cutting crank 424 via a crank hinge support shaft 423. The swing cutting crank 424 is fixedly mounted on the output shaft of the swing cutting motor 425. The swing cutting motor 425 is fixedly mounted on the saw frame 401 via a swing cutting motor base 426. The swing cutting motor 425 is a servo motor.

[0082] like Figure 20 , Figure 21 As shown, an eccentric block 428 is fixedly mounted on the swing-cutting motor shaft 427 of the swing-cutting motor 425 via a connecting key. The eccentricity of the eccentric block 428 is L. The eccentric block 428 is fixedly mounted in the eccentric block hole of the swing-cutting crank 424 via a detachable locking cone sleeve 429. Loosening the locking cone sleeve 429 can adjust the relative eccentricity of the eccentric block 428 on the swing-cutting crank 424, and tightening the locking cone sleeve 429 can fix the eccentric block 428 on the swing-cutting crank 424. By adjusting the relative position of the eccentric block 428 on the swing-cutting crank 424, different actual crank running lengths of the swing-cutting crank 424 can be obtained, thereby changing the swing amplitude of the circular saw blade swing arm 420 to adapt to the sawing requirements of wood of different thicknesses. The actual crank running length adjustment range of the swing-cutting crank 424 is 2L.

[0083] like Figure 22 , Figure 23 As shown, the locking cone sleeve 429 is a conical sleeve with an open slot, and the cone angle β of the conical sleeve is 3.5°; preferably, the cone angle β of the locking cone sleeve 429 is 3°-5°. One end of the locking cone sleeve 429 is provided with a thread for screwing in a nut. The locking cone sleeve 429 is installed in the conical hole of the swing cutting crank 424 with a conical surface. Tightening the nut locks the locking cone sleeve 429 to lock the eccentric block 428 and the swing cutting handle 424 together; loosening the locking cone sleeve 429 can adjust the relative locking position of the eccentric block 428 and the swing cutting crank 424, thereby adjusting the actual swing cutting length of the swing cutting handle 424.

[0084] like Figure 24 , Figure 25As shown, the buffer hinge 421 includes a hinge housing 4211, and a connecting rod screw hole 4215 on the hinge housing 4211 is screwed to the upper end of the connecting rod 422. The hinge housing 4211 is movably fitted onto the swing sleeve 4212, and the hinge housing 4211 can swing relative to the swing sleeve 4212. Four recesses are evenly distributed on the inner wall of the swing sleeve 4212. A winged buffer sleeve 4213 is installed in the cavity of the swing sleeve 4212. Four outwardly extending winglets are provided on the outer wall of the winged buffer sleeve 4213. The winglets extend into the corresponding recesses of the swing sleeve 4212 at intervals on both sides. Buffer elastic blocks 4214 are installed on both sides of the winglets of the winged buffer sleeve 4213 that extend into the recesses of the swing sleeve 4212. The buffer elastic blocks 4214 are rubber elastic pads, or they can be elastic components such as disc springs. The winged buffer sleeve 4213 is fixedly installed on the hinge shaft 4216, and the two protruding ends of the hinge shaft 4216 are swayably installed in the mounting holes at the front end of the circular saw blade swing arm 420.

[0085] like Figure 26 , Figure 27 and Figure 28 As shown, a sorting motor 602 and two parallel conveyor pulleys are fixedly mounted on the sorting frame 601. The sorting motor 602 drives the drive conveyor pulleys through a conveyor belt drive pair 603. A sorting conveyor belt 604 is tensioned on the two parallel conveyor pulleys. The conveyor belt drive pair 603 is a synchronous toothed belt drive pair. On one side of the sorting frame 601, there are multiple spaced-apart sorting guide side plates 605 and several pusher groups. The segmented sorting guide side plates 605 and pusher groups are staggered. Each pusher group includes two adjacent pusher cylinders 606. Each pusher cylinder 606 corresponds to a cylinder control valve 607. Compressed air is supplied to the pusher cylinder 606 through the cylinder control valve 607. The cylinder control valve 607 is a two-position five-way double-electrically controlled directional valve, and the pusher cylinder 606 is a double-acting cylinder. When one side of the cylinder control valve 607 is energized, the piston rod of the pushing cylinder 606 extends outward to complete the pushing process. When one side of the cylinder control valve 607 is de-energized and the other side is energized, the piston rod of the pushing cylinder 606 retracts inward. The extension and retraction of the piston rod of the pushing cylinder 606 are controlled by the cylinder control valve 607. The two pushing cylinders 606 in the same group can extend or retract alternately, or they can extend or retract synchronously. When the two pushing cylinders 606 extend and retract alternately, since one cylinder is in the extending pushing state while the other is in the retracted preparing pushing state, the frequency of pushing and retracting is increased, meeting the high-speed cutting requirements of the entire production line. When the two pushing cylinders 606 extend and retract synchronously, the requirements for pushing and classifying long materials can also be met.

[0086] Each pusher cylinder 606 has a pusher head 608 at the piston rod end. The pusher head 608 passes through the gap between two adjacent guide side plate sections and is located above the belt surface of the sorting conveyor belt 604. The pusher head 608 is a rubber elastic sleeve fitted onto the piston rod end of the pusher cylinder 606. Two adjacent pusher cylinders 606 in the same pusher group are mounted on the sorting frame 601 through a cylinder mounting seat 609.
