Description

Technical Field

[0001] The present invention relates to the technical field of bamboo and wood processing equipment, and particularly to an automated mechanical device for high-precision slicing of bamboo, which is applicable to efficient and precise slicing operations in the pre-treatment stage of bamboo materials. Background Art

[0002] In the bamboo processing industry, traditional bamboo slicing machines generally have the following problems:

[0003] Low slicing accuracy: Traditional equipment mostly uses fixed blades in combination with simple conveying structures, which are difficult to adapt to bamboo slices of different thicknesses, resulting in uneven slicing thickness and high scrap rates;

[0004] Poor structural stability: The mechanical transmission part is prone to wear, and the accuracy decays significantly after long-term use, resulting in high maintenance costs;

[0005] Limited adaptability: It cannot handle bent or uneven bamboo slices, and has a narrow scope of application.

[0006] In the prior art, although some equipment has tried to adjust the blade height hydraulically, there are problems such as slow response speed (adjustment time > 2 s) and high energy consumption (the power consumption of the hydraulic system accounts for 40% of the whole machine), and still cannot meet the production requirements of high precision and high efficiency. Summary of the Invention

[0007] In view of this, the present invention provides a high-precision bamboo slicing machine, aiming to solve the problems of low slicing accuracy and poor structural stability of existing bamboo slicing machines in the above-mentioned background art.

[0008] The present invention provides a high-precision bamboo slicing machine, including a centering module, a power module, a blade, a discharge port, a feed port and a control module. The discharge port and the feed port are located on both sides of the centering module. The centering module includes an upper centering module and a lower centering module that can slide relative to each other, and an upper pressure roller and a lower pressure roller for extruding and conveying materials are respectively installed on the two. The upper pressure roller and the lower pressure roller are connected to the power module. The blade is located at the discharge end between the upper pressure roller and the lower pressure roller. This technical solution ensures the stable feeding of bamboo materials along the central axis by the relative sliding of the upper and lower centering modules of the centering module, in cooperation with the extrusion and conveying of the upper pressure roller and the lower pressure roller, avoiding the deviation of bamboo materials, ensuring accurate slicing positions, and the thickness error ≤ ±0.2 mm.

[0009] Further description of the foregoing solution. The centering module further includes a lifting seat and a horizontal seat, and the horizontal seat is vertically installed on one side of the lifting seat. The lifting seat includes two vertical plates, and vertical guide rails and vertical sliders are installed inside the vertical plates. The upper centering module and the lower centering module are installed on the vertical sliders. A horizontal guide rail, a horizontal slider, a ball head, a pull rod, and a spring are installed on the horizontal seat. A first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a fifth connecting rod, and a sixth connecting rod are installed between the lifting seat and the horizontal seat. One ends of the first connecting rod and the third connecting rod are respectively fixedly connected to the upper centering module and the lower centering module. The fifth connecting rod is slidably installed on the horizontal guide rail through the horizontal slider. Two ends of the second connecting rod are respectively rotatably connected to the first connecting rod and the fifth connecting rod. Two ends of the fourth connecting rod are respectively rotatably connected to the third connecting rod and the fifth connecting rod. The middle of the sixth connecting rod is rotatably installed on the horizontal seat, and two ends of the sixth connecting rod are respectively rotatably connected to the fifth connecting rod and the pull rod. The pull rod is connected to the sixth connecting rod through the ball head, and the spring is sleeved on the pull rod. One end of the spring abuts against the horizontal seat, and the other end abuts against the nut at the end of the pull rod. The spring pulls the pull rod, and the pull rod drives the sixth connecting rod to drive the fifth connecting rod to move on the horizontal guide rail. The fifth connecting rod drives the first connecting rod, the second connecting rod, the third connecting rod, and the fourth connecting rod to make the upper centering module and the lower centering module symmetrically move up and down with the blade as the center. A six-link linkage mechanism is adopted: the spring pulls the pull rod → the sixth connecting rod rotates → drives the fifth connecting rod to slide on the horizontal guide rail → through the first and second connecting rods and the third and fourth connecting rods, the upper and lower centering modules are symmetrically lifted and lowered along the vertical guide rail; when the thickness of the bamboo changes, the module automatically adjusts the distance through the linkage mechanism, so that the bamboo is always aligned with the center of the blade, and the adjustment process does not require manual intervention. The adjustment is realized only by the spring tension and the mechanical connecting rod, the energy consumption is reduced by 25%, and the response time < 0.1 s, which is better than the hydraulic adjustment scheme. The positioning accuracy of the linkage mechanism is ±0.1 mm, and the error of the sliced thickness is controlled within ±0.2 mm, which is 50% higher than that of the traditional equipment.

[0010] Further description of the foregoing solution. The power module includes a motor and a gear set, and the motor drives the upper pressure roller and the lower pressure roller to rotate by driving the gear set. The gear set adopts closed lubrication and has high transmission efficiency.

[0011] For a further description of the foregoing solution, two upper pressing rollers and two lower pressing rollers are provided, and are drivingly connected to the upper gear and the lower gear of the gear set; the gear set further includes a driving wheel, a first transmission gear, a second transmission gear, and a third transmission gear. The driving wheel is connected to the motor through a driving shaft. The driving wheel is located between the two upper gears and drives the upper gears to rotate. The upper gears sequentially drive the first transmission gear, the second transmission gear, and the lower gears to rotate. The third transmission gear is located between the two lower gears. Two upper and lower pressing rollers are provided respectively, and are driven by the upper and lower gears of the gear set respectively to form a symmetric clamping force. The double pressing rollers symmetrically extrude, and the bamboo is stressed evenly, with a compact structure.

[0012] For a further description of the foregoing solution, the discharge port and the feed port are fixedly installed on the vertical plate by bolts, and the blade is detachably installed on the tool holder between the vertical plates. When disassembling, only the bolts need to be loosened for replacement and grinding.

[0013] For a further description of the foregoing solution, it further includes a base. The centering module is installed on the base, and the power module is located on the side of the centering module. An electric box, a foot switch or a manual switch is also installed on the base. The electric box is electrically connected to the foot switch or the manual switch and the motor.

[0014] For a further description of the foregoing solution, a protective cover is provided outside the power module. The protective cover covers the motor and the gear set to prevent foreign objects from intruding and ensure operation safety.

[0015] For a further description of the foregoing solution, a buffer block and a reinforcing plate are also installed on the vertical plate of the lifting seat. The reinforcing plate connects and fixes the tops of the two vertical plates. The buffer block is located between the top of the upper centering module and the reinforcing plate. The reinforcing plate connects the tops of the two vertical plates to form a rigid frame, enhancing the overall strength of the lifting seat and reducing the deformation of the vertical guide rail under stress; the buffer block is made of polyurethane and is located between the upper centering module and the reinforcing plate to absorb the impact and vibration during the lifting of the module.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] High-precision slicing: The upper and lower centering modules of the centering module cooperate with the pressing rollers to extrude and convey the bamboo, ensuring that the bamboo is stably fed along the central axis and avoiding deviation. The thickness error of the slices is ±0.2 mm. The six-link linkage mechanism can automatically adjust the module spacing according to the thickness of the bamboo, with an adjustment response time <0.1 s and a positioning accuracy of ±0.1 mm.

[0018] Low consumption and high efficiency: The pure mechanical drive design only relies on the spring tension and mechanical link adjustment, reducing the energy consumption by 25% compared with the traditional hydraulic solution, and solving the problems of slow response and high power consumption of the hydraulic system.

[0019] Stable and durable: The lifting seat vertical plates are connected into a rigid frame through reinforcing plates to reduce the deformation of the guide rails; the polyurethane buffer blocks absorb the impact vibration during the lifting of the module. The double pressure rollers are symmetrically driven, which can adapt to bamboo slices with bending or uneven thickness.

[0020] Safe and convenient: There is a protective cover outside the power module to prevent foreign objects from entering. The blade is detachable for easy replacement and grinding; the discharge port and the feed port are fixed with bolts, which are convenient for installation and disassembly.

These drawings and textual descriptions are not intended to limit the scope of the inventive concept in any way, but to illustrate the concept of the present invention to those skilled in the art by reference to specific embodiments. Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the drawings.

[0035] Please refer to Figures 1 - 10 As shown, the implementation of this high-precision bamboo slicing machine is based on the modular design concept, and the installation and debugging of each component need to follow strict precision standards.

[0036] The overall device consists of a base 1, a centering module 2, a power module 3, a blade 7 assembly, a feeding and discharging port 6, and a control module. During installation, first fix the base 1 on the horizontal ground and adjust the levelness through anchor bolts to ensure that the flatness error of the base 1 is within 2 mm / m. The base 1 is welded with Q235B steel plate, with a thickness of not less than 10 mm, and reinforcing rib plates are added at the bottom to bear dynamic loads. The centering module 2 is installed in the middle of the base 1. The two vertical plates of its lifting seat 21 need to be kept vertical, and the perpendicularity tolerance is controlled within 1 mm. The vertical guide rail 211 adopts a linear rolling guide rail. During installation, it is calibrated with a level to ensure that the straightness error in the vertical direction of the guide rail is ≤0.05 mm / m, and the parallelism error between the guide rails is ≤0.03 mm. The horizontal seat 22 is vertically installed on one side of the lifting seat 21, and the levelness error of the horizontal guide rail 221 needs to be ≤0.02 mm / m to ensure the smooth sliding of the horizontal slider 222. High-temperature resistant grease is applied to the hinge joints of each connecting rod of the six-link mechanism, and the clearance of the spherical plain bearing is controlled within 0.05 mm. When the spring 225 is installed, it is pre-compressed by 10 - 15 mm, and the pre-tightening force is controlled within 8 - 10 N·m by a torque wrench.

[0037] The power module 3 is located on the side of the centering module 2. The motor 31 is installed on the vertical plate through a shock pad, or it can also be connected to the base 1 through a bracket. The hardness of the shock pad is selected as Shore 50±5A to reduce vibration transmission. The blade 7 is installed on the tool holder between the vertical plates. The tool holder is quenched and tempered with 45# steel. The blade 7 is fixed with countersunk bolts, and it is necessary to ensure that the coincidence error between the cutting edge and the center lines of the upper and lower pressure rollers 262 is ≤0.1 mm. The feeding port 5 and the discharging port 6 are fixed to the outside of the vertical plate through bolts. The inlet angle of the feeding port 5 is designed as 30°, and the outlet angle of the discharging port 6 is 15° to guide the bamboo smoothly in and out.

[0038] During the commissioning of the electrical system, first conduct no-load trial operation. Connect the power supply and observe whether the rotation direction of the motor 31 is correct. The running noise of the gear set 34 should be ≤75 dB. Manually adjust the pull rod 224 to test the linkage effect of the six-link mechanism. The upper and lower centering modules 23 should be able to symmetrically lift and lower with the blade 7 as the center, with a lifting stroke of 0 - 10 mm and a repeat positioning accuracy of ≤0.1 mm.

[0039] Such as Figure 5 、 6As shown in the figure, the core of the centering module 2 is the coordinated operation of the six-link linkage mechanism and the spring 225 tension system. When the bamboo enters the equipment and contacts the pressure roller, if the thickness changes, the upper centering module 24 and the lower centering module 23 will be displaced due to extrusion. Taking the increase in the thickness of the bamboo as an example, the upper centering module 24 is driven by an upward thrust to rotate the second connecting rod 252. At the same time, the lower centering module 23 is pressed to rotate the fourth connecting rod 254. The second connecting rod 252 and the fourth connecting rod 254 together push the fifth connecting rod 255 to slide, thereby driving the sixth connecting rod 256 to rotate around the hinge point, and the spring 225 expands. The restoring force of the spring 225 is transmitted through the pull rod 224 to form a reverse torque, so that the fifth connecting rod 255 maintains dynamic balance, and the upper and lower centering modules 23 symmetrically rise and fall to ensure that the center of the bamboo is aligned with the blade 7. The response time of this mechanism is <0.1 s.

[0040] The top of the vertical plate of the lifting seat 21 is connected by a reinforcing plate 214 to form a rigid frame. The buffer block 213 is made of polyurethane material with a Shore hardness of 80±5A and a thickness of 20 mm, which can absorb impact energy, reduce the impact acceleration of the module lifting from 5g to below 1.5g, and protect the accuracy of the guide rail.

[0041] As Figure 10 As shown in the figure, the power module 3 adopts a multi-stage gear drive. The motor 31 drives the power wheel 341 through the power shaft 33. The power wheel 341 meshes with two upper gears 342 at the same time to form a symmetric drive. The left upper gear 342 drives the right lower gear 346 through the first and second transmission gears 344, and the right lower gear 346 drives the right lower gear 346 through the third transmission gear 345. The gears are made of 20CrMnTi carburized and quenched, and are lubricated by oil bath. The comprehensive transmission efficiency is ≥96%. Two upper and lower pressure rollers 262 are provided respectively, and the surfaces are processed with spiral anti-slip grooves with a groove depth of 1.5 mm and a pitch of 10 mm. They are synchronously driven by the gear set 34, and the linear velocity difference is ≤0.5%. The conveying speed is adjustable from 0.5 to 2 m / s. When processing curved bamboo, the symmetric clamping force of the double pressure rollers can correct the shape.

[0042] It should be noted that the upper gear 342 and the lower gear 346 are respectively installed on the upper centering module 24 and the lower centering module 23, and will move up and down with the upper centering module 24 and the lower centering module 23. Since the offset distance is <6 mm, during the offset process, they can still mesh with the transmission gears and the power wheel 341.

[0043] During the slicing operation, the bamboo materials need to be pre-treated to remove bamboo knots and impurities, sprayed with water to soften the bamboo materials, and loaded according to specifications. Set the rotational speed of the motor 31 through the frequency converter of the electric box 4, 1500 rpm for soft bamboo materials and 1200 rpm for hard bamboo materials, and the linear speed of the blade is 10 - 20 m / s. Start the equipment and run it without load for 1 - 2 minutes. After confirming that there is no error, load the materials. The bamboo materials are clamped and conveyed by the pressure rollers and are cut when the front end reaches the blade 7. The operator needs to observe the conveying state. The blade 7 is ground after continuous use for 8 hours and replaced when the wear exceeds 0.5 mm. After grinding, the edge angle is maintained at 25° ± 1°.

[0044] For equipment maintenance, it is necessary to check the fasteners, guide rail lubrication, spring pre-compression amount and blade wear condition daily. After the operation, clean the equipment and apply anti-rust oil. Common faults such as uneven slicing thickness may be caused by the jamming of the connecting rod, the attenuation of spring tension or the loosening of the blade. It is necessary to clean the hinge joint, replace the spring or tighten the blade accordingly.

[0045] This equipment is applicable to slicing various bamboo materials. After an enterprise replaced the equipment, the single-shift output increased from 1500 kg to 3000 kg, the waste rate decreased to 3%, the energy consumption decreased to 18 kWh / 100 kg. Through classified feeding, parameter optimization and maintenance plan, the effective operation time increased from 6.5 hours / shift to 7.8 hours / shift, and the production efficiency increased by 50%.

[0046] The equipment realizes high-precision slicing and low-consumption and high-efficiency operation through the design of six-link linkage and double-pressure roller symmetric drive. The rigid frame and buffer design in the structure enhance the stability. The gear drive of the power system ensures accurate transmission. The electrical control and safety protection ensure convenient and safe operation. It is applicable to the high-efficiency and precise slicing operation in the pre-treatment stage of bamboo materials and has significant technical advantages and economic benefits.

[0047] Those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the invention.
