Specific implementation

[0037] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below with reference to the drawings.

[0038] The embodiment of the utility model provides a kind of rubber cutting blade, and rubber cutting blade includes: first blade 100, and first blade 100 is equipped with first blade part 110;Second blade 200, and second blade 200 is equipped with second blade part 210;Knife tip 300, and knife tip 300 is protruded to form in the angle of first blade 100 and second blade 200, and knife tip 300 is duckbill structure.

[0039] As Figure 1 The utility model relates to a kind of innovative design's rubber cutting blade, its main feature is in the combination of first blade 100 and second blade 200, and the structure of knife tip 300 formed by protruding at angle is realized the promotion of rubber cutting performance. Among them, knife tip 300 is designed as duckbill tip, by improving cutting angle and local pressure, the initial distance of cutting into when cutting rubber is greatly reduced, so that rubber cutting blade has higher rubber cutting efficiency and yield. Since knife tip 300 is sunken in cutting direction, its position is just located in the key part of latex tree lactiferous duct, i.e. between the inner layer of bark and yellow skin tissue, so as to cut accurately and remove more dry, solidified lactiferous duct.

[0040] In part of the embodiments of the application, knife tip 300 includes first knife tip part 310, second knife tip part 320 and third knife tip part 330, first knife tip part 310 is smoothly connected with first blade part 110, second knife tip part 320 is smoothly connected with second blade part 210, and third knife tip part 330 is smoothly connected between first knife tip part 310 and second knife tip part 320.

[0041] As Figure 1 As shown in the figure, knife tip 300 includes first knife tip part 310, second knife tip part 320 and third knife tip part 330, and the smooth connection design and radian distribution between each knife tip 300 part and blade part have special functional optimization. The front end of the duckbill-shaped rubber cutting blade is curved, and the curved shape gradually and smoothly transitions along the cutting direction of the rubber cutting blade, and has good stability when cutting. The cutting edge of knife tip 300 is smooth and gradually changes, without sharp and sharp points.

[0042] In part of the embodiments of the application, the radian of first knife tip part 310 is greater than the radian of third knife tip part 330, and the radian of second knife tip part 320 is greater than the radian of third knife tip part 330.

[0043] As Figure 1 As shown in the figure, the radian design and special geometric structure of the blade reduce the friction and wear when cutting rubber, prolong the service life of the blade. The efficient cutting capacity of duckbill-shaped knife tip 300 reduces the replacement frequency of the blade, saves maintenance and replacement cost.

[0044] Preferably, the ratio of the width to the thickness of the tip 300 is 1.5-3; the first blade portion 110 and the second blade portion 210 form an included angle with the tip 300, and the included angle is greater than 30°.

[0045] In some embodiments of the present application, the first blade portion 110 is provided with a first inner blade surface 111 and a first outer blade surface 112 arranged oppositely; the first blade 100 is further provided with a first inner side surface 120, the first inner side surface 120 is connected with the first inner blade surface 111, and the first inner side surface 120 is arranged opposite to the first outer blade surface 112; the second blade portion 210 is provided with a second inner blade surface 211 and a second outer blade surface 212 arranged oppositely; the second blade 200 is further provided with a second inner side surface 220, the second inner side surface 220 is connected with the second inner blade surface 211, and the second inner side surface 220 is arranged opposite to the second outer blade surface 212; wherein, the connection between the first inner side surface 120 and the first inner blade surface 111 forms a first connection line 130, the connection between the second inner side surface 220 and the second inner blade surface 211 forms a second connection line 230, and the included angle formed by the first connection line 130 and the second connection line 230 is a first included angle, the first included angle is A, and 40°≤A≤90°.

[0046] As shown in Figures 2-4 , the special connection geometry between the inner blade surface and the inner side surface of the blade ensures that the blade can maintain high cutting performance during work. The first blade portion 110 and the second blade portion 210 are arranged to form a cutting relationship that cooperates with each other, and the included angle is controlled between 40° and 90°, which ensures that the blade has both sufficient sharpness and certain mechanical strength. When A is close to 40°, the blade has higher cutting sharpness; when A is close to 90°, the structural strength of the blade is higher, and through reasonable distribution of force, the wear rate of the blade is reduced, and the service life is prolonged.

[0047] In some embodiments of the present application, the tip 300 is provided with a third inner blade surface 340 and a third outer blade surface 350 arranged oppositely; wherein, the connection between the third inner blade surface 340 and the first inner side surface 120 forms a third connection line 360, the connection between the third inner blade surface 340 and the second inner side surface 220 forms a fourth connection line 370, and the included angle formed by the third connection line 360 and the fourth connection line 370 is a second included angle, the second included angle is B, and the second included angle is smaller than the first included angle.

[0048] As shown in Figures 2-4As shown, the cutting tip 300 has a third inner cutting surface 340 and a third outer cutting surface 350 arranged opposite to each other, forming the core cutting area of ​​the cutting tip 300. The third inner cutting surface 340 is connected to the first inner surface 120 and the second inner surface 220, forming two connecting lines. The first included angle determines the overall cutting angle and applicable range of the blade, favoring a design for macroscopic cutting; the second included angle focuses more on the local geometric optimization of the cutting tip 300, adapting to more precise cutting needs. The included angle between the third connecting line 360 ​​and the fourth connecting line 370 is smaller than the first included angle, ensuring the formation of the duckbill-shaped cutting tip 300, reducing the operating resistance of the cutting tip 300, and allowing it to easily penetrate the bark of the rubber tree.

[0049] In some embodiments of this application, the first inner cutting surface 111 includes an inner cutting surface a113, and the angle formed by the inner cutting surface a113 and the first outer cutting surface 112 is a first inclination angle, the first inclination angle being C, 0°≤C≤40°; and / or the first inner cutting surface 111 includes an inner cutting surface b114, and the angle formed by the inner cutting surface b114 and the first outer cutting surface 112 is a second inclination angle, the second inclination angle being D, 0°≤D≤40°; wherein, the first inclination angle is not less than the second inclination angle.

[0050] like Figures 6-7 As shown, by setting two adjacent partitions on the first inner cutting surface 111, namely inner cutting surface a113 and inner cutting surface b114, and by finely controlling the inclination design of the angle between inner cutting surfaces a113 and b114 and the first outer cutting surface 112, namely the first inclination angle C and the second inclination angle D, the efficiency and precision of the blade cutting process are improved. Specifically, the portion of inner cutting surface a113 near the blade tip 300 is used to complete the initial cutting action; inner cutting surface b114 is located after inner cutting surface a113 and is used to control the depth and stability of subsequent cutting processes.

[0051] The first tilt angle C is formed by the inner cutting surface a113 and the first outer cutting surface 112, primarily optimizing the cutting ability in the tip 300 region. When C is smaller, the tip 300 is sharper, the initial resistance to penetrating the bark is less, and the cut is easier. The second tilt angle D is specifically the angle formed by the relatively parallel surfaces on the inner cutting surface b114 and the first outer cutting surface 112, mainly affecting the stability in the middle of the cut. The inner cutting surfaces a113 and b114 form a reasonable geometric transition through different tilt angle designs, ensuring a smooth transition in the blade's performance from the initial cut to the middle and later stages of the cut.

[0052] like Figure 7As shown, in some embodiments, in order to more clearly illustrate the first inclination angle C and the second inclination angle D, an auxiliary surface 160 is provided on the first blade 100, which is parallel to the first outer blade surface 112 and intersects with the first inner blade surface 111, and is at the junction of the inner blade surface a113 and the inner blade surface b114. When C = 0°, 0° < D ≤ 40°, only the first outer blade surface 112 and the inner blade surface b114 exist on the rubber cutting blade at this time; when 0° < C ≤ 40°, 0° < D ≤ 40°, the first outer blade surface 112, the inner blade surface a113 and the inner blade surface b114 exist on the rubber cutting blade at the same time; when 0° < C ≤ 40°, D = 0°, only the first outer blade surface 112 and the inner blade surface a113 exist on the rubber cutting blade at this time; the first inclination angle C and the second inclination angle D are not both 0°.

[0053] In some embodiments of the present application, the width of the inner blade surface a113 is E, and 0 mm ≤ E ≤ 2 mm.

[0054] As Figure 8 shown, the inner blade surface a113 is located at the part of the first inner blade surface 111 close to the tip 300 and is used for the initial stage of cutting. Among them, the width E refers to the width range of the inner blade surface a113 on the blade edge. When E is close to 0 mm, the blade has the characteristic of a sharper tip 300, stronger piercing ability, and can significantly reduce the resistance in the initial cutting stage. When E increases to be close to 2 mm, the blade has a wider blade contact surface, and the friction force distribution during the cutting process is more uniform. Those skilled in the art can reasonably set the specific value of E so that the blade can adapt to different rubber cutting requirements, such as bark thickness, latex duct distribution, etc. Further, the width E of the inner blade surface a113 is set within a reasonable range, combined with the design of the inclination angle, which can accurately control the cutting depth and avoid over-deep cutting damage to the latex ducts; realize the control of the loss of latex and improve the latex collection efficiency.

[0055] As Figures 7-8 shown, in some embodiments, the width E of the inner blade surface a113 is related to the first inclination angle C of the inner blade surface a113. When the first inclination angle C of the inner blade surface a113 = 0°, the inner blade surface a113 does not exist, so the width E of the inner blade surface a113 = 0 mm; when the first inclination angle C of the inner blade surface a113 is 0° < C ≤ 40°, the width of the inner blade surface a113 is 0 mm < G ≤ 2 mm.

[0056] In some embodiments of the present application, the first blade 100 includes a blade part 140 and a fitting part 150 that cooperate with each other. The first blade part 110 is formed on the side of the blade part 140 away from the fitting part 150; among them, the thickness of the fitting part 150 is F, and 0.5 mm ≤ F ≤ 3 mm.

[0057] As Figure 5As shown, the blade portion 140 serves as the core cutting part of the blade, which is used to complete the rubber cutting or other cutting tasks. The matching portion 150 serves as the part connecting the blade with the support or mounting component, which is mainly responsible for structural support and assembly fixation. The first blade portion 110 is arranged on the side of the blade portion 140 away from the matching portion 150, which is the specific blade position to realize the actual cutting function.

[0058] In the matching portion 150, when F is small, the matching portion 150 is thin, which can make the blade lighter, suitable for low resistance or light cutting scenarios, but the carrying capacity is limited, suitable for application scenarios with high requirements for lightness and high precision. When F is large, the matching portion 150 is thick, which can significantly improve the overall rigidity and durability of the blade, reduce the risk of deformation or damage of the blade in high-strength cutting operations, and is suitable for high-strength or continuous rubber cutting scenarios. Those skilled in the art can select a suitable thickness of the matching portion 150, so that the blade can adapt to various cutting demands, and achieve the best balance between strength and flexibility.

[0059] Preferably, a smaller E value and a larger inclination angle C can improve the initial penetration ability and flexibility of the blade when the F value is small. A larger E value and a smaller inclination angle C can enhance the cutting stability and durability of the blade when the F value is large.

[0060] As shown, Figures 12-13 The duckbill-shaped structure is an extension of the blade tip 300 on the rubber cutting blade, which acts on the irregular surface of the rubber tree and can better cut into the rubber tree. The cut rubber strip and rubber wood chips are smoothly pushed out along the duckbill-shaped structure.

[0061] In some embodiments of the present application, the length of the first blade portion 110 is G, and 5mm≤G≤30mm; the length of the second blade portion 210 is H, and 10mm≤H≤50mm.

[0062] As shown, Figure 5 The combination of the first blade portion 110 and the second blade portion 210 enables the blade to complete both high-precision, shallow cutting and large-range, deep continuous cutting operations. The length of the first blade portion 110 is shorter than that of the second blade portion 210, which reflects the functional division between initial cutting and continued cutting, thereby improving the overall cutting efficiency and performance of the blade; wherein the length limitation of the first blade portion 110 makes the initial cutting process more stable, avoiding sudden penetration or deviation of the blade, and the length range of the second blade portion 210 improves the support effect in the cutting process, reducing the risk of blade loosening or falling off. The length range of the first blade portion 110 and the second blade portion 210 cooperates with other geometric parameters of the blade, such as the blade width E, the inclination angle C, and the thickness F of the matching portion 150, to optimize the performance of the blade.

[0063] In some embodiments, the first blade 100 and the second blade 200 are made of alloy materials and are connected to each other by bending or welding. The blades can be manufactured by using common grinding methods such as concave grinding, convex grinding, and chisel grinding, which reduces the manufacturing difficulty compared with the rubber cutting blades in the prior art. The alloy materials selected for the rubber cutting blades are materials with high strength and low reactivity with target objects, such as tungsten steel, stainless steel, and metal ceramic.

[0064] The embodiment of the utility model provides a kind of rubber cutting device, and rubber cutting device includes the rubber cutting blade as described above, and rubber cutting device includes: guide rail 10, guide rail 10 is installed on rubber tree to fix rubber cutting device;Vehicle-mounted frame mechanism 20, vehicle-mounted frame mechanism 20 is movably connected to guide rail 10;Tool rest mechanism 30, tool rest mechanism 30 is equipped with rubber cutting blade;Wherein, vehicle-mounted frame mechanism 20 and tool rest mechanism 30 are drivingly connected, to drive tool rest mechanism 30 to carry out spiral trajectory cutting action to rubber tree.

[0065] As shown in Figure 9 The rubber cutting device based on the rubber cutting blade of innovative design realizes spiral trajectory cutting operation to rubber tree by introducing the cooperative work of guide rail 10, vehicle-mounted frame mechanism 20 and tool rest mechanism 30. Through mechanized and automated rubber cutting operation, the problems of low efficiency, poor precision and high labor intensity of traditional manual rubber cutting are solved.

[0066] Guide rail 10 is installed on the surface of rubber tree and serves as fixed support structure of rubber cutting device, and the setting of guide rail 10 guarantees the stability of rubber cutting device and the controllability of rubber cutting path. Vehicle-mounted frame mechanism 20 is movably connected to guide rail 10 and is used to move along the trajectory of guide rail 10. The movement of vehicle-mounted frame mechanism 20 provides stable power transmission for rubber cutting blade and realizes spiral cutting along the trunk. Tool rest mechanism 30 is provided with rubber cutting blade and is drivingly connected with vehicle-mounted frame mechanism 20. The design of tool rest mechanism 30 enables rubber cutting blade to cut the surface of rubber tree at appropriate angle and pressure, avoiding excessive damage to the trunk.

[0067] The rubber cutting process of the device is completed by the movement of vehicle-mounted frame mechanism 20 and the cutting action of tool rest mechanism 30, and the whole operation is fully automated. The geometric design of rubber cutting blade is highly matched with guide rail 10, vehicle-mounted frame mechanism 20 and tool rest mechanism 30 of the device, further optimizing the performance and applicability of rubber cutting device. By moving vehicle-mounted frame mechanism 20 along guide rail 10 and cooperating with tool rest mechanism 30, spiral trajectory cutting operation is realized, greatly improving the speed of rubber cutting.

[0068] As shown in Figure 12 In one embodiment, the sinking angle K of the position of blade tip 300 in rubber cutting blade is 28.96°±0.01° during rubber cutting operation.

[0069] In some embodiments, the tool holder mechanism 30 is provided with a mounting mechanism 40; the mounting mechanism 40 consists of a tool head 41 and a connecting part 42, the tool head 41 is connected to the connecting part 42, the tool head 41 is used to mount the rubber cutting blade, and the connecting part 42 is used to connect the tool head 41 and the tool holder mechanism 30.

[0070] like Figure 10 As shown, by setting an installation mechanism 40 on the blade holder mechanism 30, convenient installation and secure connection of the rubber tapping blade are achieved. The installation mechanism 40 consists of a blade head 41 and a connecting part 42, wherein the blade head 41 is used to install the rubber tapping blade, and the connecting part 42 is used to connect the blade head 41 and the blade holder mechanism 30. This design significantly improves the installation efficiency, stability, and ease of replacement of the rubber tapping blade, while ensuring the high efficiency and safety of rubber tapping operations.

[0071] like Figure 11 As shown, the cutter head 41 is provided with a first connecting hole 43 and a first connecting shaft 44. The first connecting hole 43 and the first connecting shaft 44 cooperate with each other to connect the cutter head 41 to the connecting part 42. The connecting part 42 is also provided with a second connecting hole 45, which is a cylindrical hollow structure. By adding a cylindrical second connecting shaft 46 into the hollow structure, the length of the second connecting shaft 46 is slightly greater than the length of the second connecting hole 45. The part of the connecting shaft that extends beyond the two ends of the second connecting hole 45 is a protruding structure to realize the connection between the mounting mechanism 40 and the tool holder mechanism 30.

[0072] In some embodiments, the blade head 41 is provided with a fastener 47 and an adjusting member 48; the fastener 47 is used to fix the rubber cutting blade to the mounting mechanism 40, and the adjusting member 48 is used to adjust the position of the rubber cutting blade on the mounting mechanism 40.

[0073] like Figures 12-13 As shown, by setting fasteners 47 and adjusting members 48 on the blade head 41, the rubber tapping blade is securely installed and its position is precisely adjusted. Fasteners 47 are used to firmly fix the rubber tapping blade to the mounting mechanism 40, preventing the blade from loosening, shifting, or falling off due to high-frequency vibrations during the tapping process. Adjusting members 48 are used to precisely adjust the position of the rubber tapping blade on the mounting mechanism 40, including the blade's working angle, depth, and cutting direction, to adapt to different tapping needs. This design ensures the stability of the rubber tapping blade while improving accuracy and operational flexibility during the tapping process.

[0074] Preferably, the fastener 47 can adopt a pressure plate, snap-fit, or clamping structure, which combines ease of installation with stability. The adjusting component 48 can adopt a screw-type or knob-type adjustment method to ensure adjustment accuracy and ease of operation. After adjustment, the adjusting component 48 can lock the blade position to prevent accidental displacement during operation.

[0075] It should be noted that, since the tapping blade in the present application is composed of two similar blades, the first inclination angle C, the second inclination angle D, the width E, and the thickness F in the embodiments of the present application are exemplified by the data on the first blade 100, which are also applicable to the second blade 200.

[0076] Although the utility model discloses as above, the utility model is not limited to this.
