[0039] Embodiment:
[0040] An efficient cutting device for ramie processing includes a bearing plate 10 and a support frame 80 with an open top surface. The bearing plate 10 is installed on a part of the top surface of the support frame 80. On the part of the top surface of the support frame 80 where the bearing plate 10 is not installed, an anti-warping frame plate 70 is installed, and a clamping component 50 is connected to the bottom surface of the anti-warping frame plate 70;
[0041] On the top surface of the bearing plate 10, a guiding component 20 and a pushing component 30 are arranged. The guiding component 20 and the pushing component 30 are arranged in parallel with each other, and one end of the pushing component 30 abuts against the clamping component 50;
[0042] The guiding component 20 includes a guiding plate 210 arranged on the top surface of the bearing plate 10. On the top surface of the guiding plate 210, a plurality of guiding grooves 220 parallel to the pushing component 30 are opened;
[0043] The pushing component 30 includes a guide rail 310 and an electric slider 320 slidably connected to the guide rail 310. On the top surface of the electric slider 320, a push plate 330 is arranged. On the push plate 330, there are push teeth equal in number to the guiding grooves 220, and the push teeth are respectively located inside the guiding grooves 220;
[0044] Outside the clamping component 50, a cutting component for cutting ramie rods is also arranged.
[0045] It is explained that when performing the ramie stalk cutting operation, the operator only needs to place the ramie stalk into the guiding groove 220 on the guiding plate 210. After starting the pushing device, the electric slider 320 will drive the pushing plate 330 to perform a reciprocating linear motion, and use the pushing teeth on the pushing plate 330 to push the ramie stalk into the clamping component 50. The fixing hole 550 in the clamping seat 510 then fixes the ramie stalk. Subsequently, the cutting component is selected to cut the ramie stalk. Through the coordinated action of the guiding component 20, the pushing component and the cutting component, the machine can efficiently replace manual labor to push the ramie stalk under the cutter, ensuring the high efficiency of the cutting process.
[0046] Combined with the accompanying drawings of the specification Figures 1-9 As shown, a placing and removing concave surface 230 is further provided on the said guiding plate 210. The placing and removing concave surface 230 has at least three and is arranged in a linear array on the top surface of the guiding plate 210. Among them, the setting of the placing and removing concave surface 230 is to further improve the convenience and efficiency of the operator when placing and removing the ramie stalk. Each placing and removing concave surface 230 is designed into a shape matching the guiding groove 220, so that the operator can easily place the ramie stalk on the concave surface and send it into the guiding groove 220 through a simple sliding action.
[0047] Specifically, during the actual operation process, the operator can first place a bunch of ramie stalks on the placing and removing concave surface 230, and then through a slight push of the finger, make each ramie stalk slide into the corresponding guiding groove 220 in turn. Since the placing and removing concave surface 230 is arranged in a linear array, the operator can process multiple ramie stalks at the same time, greatly improving the work efficiency. In addition, the setting of the placing and removing concave surface 230 also helps to reduce the hand fatigue of the operator when placing and removing the ramie stalk. Since the shape of the concave surface adapts to the outer shape of the ramie stalk, when the operator performs the sliding action, the operator can more easily control the strength and direction, avoiding fatigue or accidental injury caused by improper force.
[0048] Combined with the accompanying drawings of the specification Figures 1-9As shown, the cutting component includes a first cutting component 40 and a second cutting component 60, the first cutting component 40 is installed on the top of the clamping component 50 and is perpendicular to the guide plate 210, the second cutting component 60 is installed at the top and bottom of the clamping component 50, the clamping component 50 includes a clamping seat 510 that contacts the guide plate 210, a feeding trough 520 is provided on the top of the clamping seat 510, and a fixing hole 550 is provided on the end surface of the clamping seat 510 that contacts the guide plate 210, and the number of the fixing holes 550 is the same as that of the guide plate 210. The number of grooves 220 is adapted, and the inside of the clamping seat 510 is further provided with a first knife groove 530 and a second knife groove 540, respectively. The first knife groove 530 and the second knife groove 540 correspond to the first cutting component 40 and the second cutting component 60, respectively. The clamping seat 510 includes a first part and a second part which are interconnected, the first part is a rectangle, and the second part is a triangle. A part of the feed trough 520 is horizontally opened inside the rectangle of the first part, and another part of the feed trough 520 is obliquely opened inside the triangle of the second part.
[0049] It is explained that horizontal cutting of ramie rods and oblique cutting of ramie rods are different, wherein oblique cutting is suitable for scenes with high requirements on ramie fiber quality, such as the situation in the textile industry where fiber integrity needs to be maintained, while horizontal cutting is suitable for scenes with low requirements on fiber quality, or when high efficiency and large-scale production are required. Whether to choose oblique cutting or horizontal cutting of ramie rods should be determined according to specific needs. If the integrity of the fiber and high product quality are pursued, oblique cutting is more appropriate; while if the simplicity of operation and the economy of the equipment are emphasized, horizontal cutting may be a more practical choice. Therefore, when performing the cutting operation, the operator first fixes the ramie rod placed in the guide groove 220 through the clamping component 50. Subsequently, the operator can choose to use the first cutting component 40 or the second cutting component 60 to cut the ramie stem horizontally or obliquely according to actual needs. Since the clamping seat 510 is provided with a first knife groove 530 and a second knife groove 540 corresponding to the cutting component, during the cutting process, the first cutting component 40 and the second cutting component 60 can accurately align and cut the ramie stem.
[0050] Specifically, in order to further improve the working efficiency, the feeding chute 520 of the clamping seat 510 is designed to be divided into two parts, one part is horizontally opened in the rectangular part, and the other part is inclinedly opened in the triangular part. This design enables the cut hemp stalks to automatically slide into the feeding chute 520 under the action of gravity, reducing the auxiliary actions of the operator, thereby improving the overall working efficiency.
[0051] Combined with the accompanying drawings Figures 1-9As shown in the figure, the first cutting member 40 includes a fixing plate 410. The bottom of the fixing plate 410 is screwed to the clamping seat 510. An air cylinder mounting plate 420 is screwed to the end face of the upper part of the fixing plate 410 facing the pushing member 30. A first air cylinder group 430 is mounted on the end face of the air cylinder mounting plate 420. A first connecting plate 440 is mounted on the piston end of the first air cylinder group 430. A first tool rest seat 450 is connected to the first connecting plate 440. A first cutting knife 460 for horizontally cutting ramie rods is detachably connected inside the first tool rest seat 450. The blade thickness and blade length of the first cutting knife 460 are smaller than the knife groove width and knife groove length of the first knife groove 530.
[0052] It should be noted that in actual operation, when the operator selects to use the first cutting member 40 for horizontal cutting, the first air cylinder group 430 will drive the first connecting plate 440 and the first tool rest seat 450, so that the first cutting knife 460 moves horizontally, thereby realizing the horizontal cutting of the ramie rods placed in the guiding groove 220. Since the blade thickness and blade length of the first cutting knife 460 are smaller than the knife groove width and knife groove length of the first knife groove 530, during the cutting process, the first cutting knife 460 can easily pass through the fixing hole 550 in the clamping seat 510, ensuring the cutting accuracy and efficiency.
[0053] It is worth noting that the advantage of horizontal cutting is that it is easy to operate, suitable for mass production, and can quickly complete the cutting task of a large number of ramie rods. In addition, the horizontal cutting method causes relatively less damage to the fibers during the cutting process, which helps to maintain the integrity of the fibers, thereby improving the quality of subsequent processing to a certain extent.
[0054] Combined with the attached drawings of the specification Figures 1-9 As shown in the figure, the second cutting member 60 includes a second air cylinder group 610. The second air cylinder group 610 is inclinedly mounted on the bottom surface of the triangular second part. A second connecting plate 620 is provided at the piston end of the second air cylinder group 610. A second tool rest seat 630 is connected to the second connecting plate 620. A second cutting knife 640 for obliquely cutting ramie rods is detachably connected inside the second tool rest seat 630. The blade thickness and blade length of the second cutting knife 640 are smaller than the knife groove width and knife groove length of the second knife groove 540.
[0055] It should be noted that in actual operation, when the operator selects to use the second cutting component 60 for oblique cutting, the second cylinder group 610 will drive the second connecting plate 620 and the second tool rest base 630, causing the second cutting tool 640 to move obliquely, thereby realizing the oblique cutting of the ramie rods placed in the guiding groove 220. Since the blade thickness and blade length of the second cutting tool 640 are smaller than the groove width and groove length of the second tool groove 540, during the cutting process, the second cutting tool 640 can easily pass through the fixing hole 550 in the clamping seat 510, ensuring the cutting accuracy and efficiency.
[0056] Furthermore, it is worth noting that the advantage of oblique cutting is that it can better maintain the integrity of ramie fibers, which is particularly important for the production of high-quality textiles. The design of the oblique cutting angle makes the stress distribution on the fibers more uniform during the cutting process, thereby reducing the possibility of fiber breakage. In addition, oblique cutting can also reduce the friction between fibers, further improving the quality of textiles.
[0057] Specifically, in order to ensure the accuracy of oblique cutting, the inclination angle of the second tool rest base 630 matches the installation angle of the second cylinder group 610, ensuring the stability and consistency of the second cutting tool 640 during the cutting process. At the same time, the detachable connection design inside the second tool rest base 630 makes the replacement and maintenance of the second cutting tool 640 more convenient, improving the use efficiency and service life of the equipment.
[0058] In the actual production process, the operator can flexibly select the first cutting component 40 or the second cutting component 60 according to production requirements. For occasions that require large-scale production, horizontal cutting can significantly improve production efficiency; while for occasions that pursue high-quality textiles, oblique cutting can provide better fiber integrity. By reasonably selecting the cutting method, the best balance between production efficiency and product quality can be achieved.
[0059] Combined with the accompanying drawings of the specification Figures 1-9 As shown, a collecting plate 90 is further provided on the frame of the support frame 80 close to the anti-warping plate 70. The collecting plate 90 is a concave plate, and the concave direction faces the pushing component 30. The function of the collecting plate 90 is to prevent the cut ramie rod joints from falling into the inside of the support frame 80, thereby avoiding increasing the difficulty for the operator to collect them and consuming manual working hours.
[0060] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
