Description

Technical Field

[0001] This utility model relates to the field of hemp processing technology, specifically to a device for filtering and cutting off damaged hemp fibers. Background Technology

[0002] Hemp, or cannabis, is an annual erect herbaceous plant belonging to the Cannabaceae family and the Cannabis genus. The fibers of the hemp stem bark are long and tough. Among the many types of hemp, hemp is particularly prized. Hemp fibers are very soft and have exceptionally high toughness. The tips are blunt and rounded, unlike the sharp tips of ramie and flax. Fabrics woven from hemp are fine and white, with a fineness only one-third that of ramie. They lack the itchiness and roughness of other hemp textiles. Clothes made from hemp fibers are as light as silk and softer and more comfortable than cotton clothing, making them widely used in the textile industry.

[0003] A search revealed a Chinese patent application (202420593094.7) disclosing a filtering and cutting device for hemp fibers. This patent utilizes a combination of a processing box, an outer shell, a processing table, a feed pipe, a hydraulic cylinder, a pressure plate, a linear guide, a guide slider, a slide groove, a long cutting plate, a cutting blade, and adjustment components to achieve semi-automatic filament cutting. While convenient to operate and significantly reducing worker workload, the patent employs a sealed processing box to enclose the entire cutting mechanism. While this design may offer some protection, it inconveniences workers during operation. The sealed nature of the processing box makes it difficult for workers to clearly identify the specific location of the hemp fibers during cutting, hindering precise calibration and fine-tuning. This reduces the device's practicality and makes it difficult to meet the precision requirements of actual processing.

[0004] Therefore, it is necessary to study a filtering and interception device for hemp fibers. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a filtering and cutting device for hemp fibers. This device eliminates the need for a sealed processing box, allows workers to easily observe the position of the hemp fibers for calibration and fine-tuning, and achieves efficient and accurate cutting of hemp fibers through the coordinated operation of various components. This solves the problem in the prior art where the use of a sealed processing box makes it difficult for workers to identify the position of the hemp fibers, affecting calibration and fine-tuning and reducing practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filtering and cutting device for hemp fibers, comprising a workbench, a support frame fixedly connected to the rear side of the workbench, a sliding groove on the front side of the support frame, a slider symmetrically slidably connected inside the sliding groove, a translation frame fixedly connected to the outer side of the slider, a hydraulic telescopic rod fixedly connected to the top of the translation frame, the output end of the hydraulic telescopic rod extending into the interior of the translation frame and fixedly connected to a clamping plate, a lifting frame fixedly connected to the inner side of the clamping plate, a storage groove on the bottom of the lifting frame, an electric push rod symmetrically fixedly connected to the top of the lifting frame, the output end of the electric push rod extending into the interior of the storage groove and fixedly connected to a cutting tool, and the cutting tool slidably connected to the storage groove, a transmission groove symmetrically opened at the center of the surface of the support frame, a lead screw rotatably connected inside the transmission groove via a bearing, and the lead screw being driven by a servo motor, a transmission block threadedly connected to the surface of each of the two lead screws, and the transmission block slidably connected to the transmission groove, the other end of each of the two transmission blocks being fixedly connected to the two translation frames respectively.

A hydraulic telescopic rod 6 is fixedly connected to the top of the translation frame 5. The output end of the hydraulic telescopic rod 6 extends into the interior of the translation frame 5 and is fixedly connected to a clamping plate 7. A lifting frame 8 is fixedly connected to the inner side of the clamping plate 7. A storage groove 9 is opened at the bottom of the lifting frame 8. An electric push rod 10 is symmetrically fixedly connected to the top of the lifting frame 8. The output end of the electric push rod 10 extends into the interior of the storage groove 9 and is fixedly connected to a cutting tool 11. The cutting tool 11 is slidably connected to the storage groove 9. The support frame 2 has symmetrically symmetrically arranged transmission grooves 12. The inside of the transmission grooves 12 is rotatably connected to the lead screws 13 through bearings. The lead screws 13 are driven by servo motors. The surfaces of the two lead screws 13 are threaded with transmission blocks 14, and the transmission blocks 14 are slidably connected to the transmission grooves 12. The surfaces of the lead screws 13 are covered with retractable protective sleeves, and the two ends of the protective sleeves are sealed to the transmission grooves 12 and the transmission blocks 14, respectively, which can play a dustproof role and thus improve the service life of the lead screws 13. The other ends of the two transmission blocks 14 are fixedly connected to the two translation frames 5, respectively. The four corners of the bottom of the worktable 1 are fixedly connected with electric lifting legs, and the four electric lifting legs are synchronously raised and lowered through a synchronizer. The height of the worktable 1 can be adjusted to adapt to different operating needs.

[0018] refer to Figure 1 and Figure 2 A drop opening 15 is provided at the center of the top of the workbench 1. A support plate 16 is symmetrically slidably connected to both sides of the drop opening 15. A threaded groove 17 is provided on the outer side of the support plate 16. A transmission motor 18 is symmetrically fixedly connected to the outer side of the workbench 1. The output shaft of the transmission motor 18 is fixedly connected to a transmission rod 19 through a coupling. The transmission rod 19 is threadedly connected to the threaded groove 17. A collection hopper 20 is provided at the bottom of the drop opening 15.

[0019] As a technical optimization of this utility model, the qualified hemp after cutting is received by the drop port 15 of the workbench 1, and the bottom collection hopper 20 realizes automatic collection, keeping the workbench clean and simplifying the sorting process. The bearing plate 16 drives the transmission rod 19 to rotate in the threaded groove 17 through the transmission motor 18 to adjust the spacing, adapt to hemp of different widths, and improve versatility.

[0020] refer to Figure 1 and Figure 2 A baffle 21 is fixedly connected to one side of the workbench 1, and the baffle 21 is slidably connected to the translation frame 5. A controller 22 is fixedly connected to the outside of the baffle 21, and the surface of the controller 22 is provided with a human-machine interface.

[0021] As a technical optimization of this utility model, the baffle 21 is slidably connected to the translation frame 5, which not only helps to limit the translation frame 5 to ensure its synchronous movement, but also prevents cutting debris from splashing, ensuring operational safety. The controller 22 and human-machine interface on the baffle 21 can centrally control the parameters of components such as the hydraulic telescopic rod 6, servo motor, and electric push rod 10, realizing full-process visual operation, facilitating quick parameter adjustment, reducing operation difficulty, and improving the ease of use of the device.

[0022] refer to Figure 3 and Figure 4 A protective strip 23 is fixedly connected to the inner side of the translation frame 5. A cutting groove is provided on the top of the protective strip 23, and the cutting groove is located directly below the cutting tool 11.

[0023] As a technical optimization of this utility model, the top cutting groove of the protective strip 23 on the inner side of the translation frame 5 is located directly below the cutting tool 11. This provides cutting space for the cutting tool 11, ensuring that the hemp is completely cut and avoiding the production of defective products. It also prevents the cutting tool 11 from directly contacting the translation frame 5, reducing tool wear and frame damage, extending the service life of the device, and ensuring cutting stability.

[0024] refer to Figure 4 The top of the clamping plate 7 is symmetrically fixedly connected to the limiting post 24, and the limiting post 24 is connected to the translation frame 5.

[0025] As a technical optimization of this utility model, the limiting post 24 at the top of the clamping plate 7 is connected to the translation frame 5. When the hydraulic telescopic rod 6 drives the clamping plate 7 to rise and fall, its movement trajectory is restricted to prevent tilting and deviation. This ensures that the clamping plate 7 has a uniform clamping force on the head and tail of the hemp, avoids displacement, and further improves the cutting accuracy.

[0026] refer to Figure 4 A limiting groove 25 is symmetrically provided on the side of the translation frame 5 near the lifting frame 8. A limiting block 26 is symmetrically fixedly connected to the surface of the lifting frame 8, and the limiting block 26 is slidably connected to the limiting groove 25.

[0027] As a technical optimization of this utility model, the limiting groove 25 of the translation frame 5 and the limiting block 26 of the lifting frame 8 are slidably engaged to provide precise guidance for the lifting frame 8 to rise and fall, ensuring that the electric push rod 10 drives the cutting tool 11 to cut perpendicular to the hemp surface, avoiding the cutting skew caused by the tool tilting, ensuring that the hemp cut is flat, and improving the consistency of product quality.

[0028] The working principle and usage process of this utility model are as follows: When using this filtering and cutting device to filter and cut hemp fibers, firstly, according to the width of the hemp, the controller 22 starts the transmission motor 18. The output shaft of the transmission motor 18 drives the transmission rod 19 to rotate through the coupling. The transmission rod 19 rotates in the threaded groove 17 on the outside of the support plate 16, thereby adjusting the distance between the two support plates 16 to meet the placement requirements of the hemp. At the same time, the controller 22 controls the electric lifting legs at the four corners of the bottom of the workbench 1 to adjust the height of the workbench 1 according to the operational requirements. After the adjustment is completed, one end of the hemp is passed through the translation frame 5 on one side and extends into the interior of the other translation frame 5. Next, the controller 22 activates the hydraulic telescopic rod 6 on one of the translation frames 5. The output end of the hydraulic telescopic rod 6 pushes the clamping plate 7 down. During the descent of the clamping plate 7, the limiting post 24 at the top of the clamping plate 7 cooperates with the translation frame 5 to restrict the movement trajectory of the clamping plate 7 and prevent it from tilting or deviating. This allows the clamping plate 7 to stably clamp one end of the hemp. After clamping is completed, the controller 22 activates the servo motor. The servo motor drives the lead screw 13 in the transmission groove 12 on the surface of the support frame 2 to rotate. The transmission block 14 on the surface of the lead screw 13 slides in the transmission groove 12, causing the translation frame 5, which is fixedly connected to the transmission block 14, to move through the slider 4 in the slide groove 3 on the front of the support frame 2. The sliding mechanism moves the translation frame 5, which holds the hemp head, to the designated cutting position. Then, the controller 22 activates the hydraulic telescopic rod 6 on another translation frame 5, causing the clamping plate 7 inside that frame to descend and clamp the tail of the hemp. At this time, the controller 22 activates the electric push rods 10 on both translation frames 5. The output of the electric push rods 10 pushes the cutting tool 11 to extend from the storage groove 9 at the bottom of the lifting frame 8. During the descent of the cutting tool 11, the limiting block 26 on the surface of the lifting frame 8 slides within the limiting groove 25 on the side of the translation frame 5 closest to the lifting frame 8, providing precise guidance to the lifting frame 8 and aligning the cutting tool 11 with the top of the inner protective strip 23 of the translation frame 5. The cutting groove of the workbench 1 is used to cut hemp. During the cutting process, the baffle 21 on one side of the workbench 1 slides and engages with the translation frame 5 to help limit the translation frame 5 and prevent debris from splashing. After the cutting is completed, the cutting blade 11 is retracted into the storage groove 9 under the drive of the electric push rod 10. The clamping plate 7 is raised and released from the hemp under the drive of the hydraulic telescopic rod 6. The cut qualified hemp falls into the collection hopper 20 at the bottom through the drop hole 15 at the top center of the workbench 1. The bad hemp fibers located at the head and tail are cleaned and collected by the external collection device. The entire process can be parameter set and operated through the human-machine interface on the surface of the controller 22 to realize full-process visualization and automated operation.
