This invention provides a snowflake-shaped bamboo filament cutting and sorting device. The device includes a base with two first vertical plates vertically arranged on both sides of the front end, and a rotatable shaft between the two first vertical plates. In operation, the snowflake-shaped bamboo filament cutting and sorting device first places a roll of raw material wound with snowflake-shaped bamboo filaments onto an unwinding roller. The bamboo filaments pass sequentially through a guide assembly and a guide plate to the front end of the worktable. A clamping assembly pulls the bamboo filaments to a suitable position, with one end of the filament acting as the worktable's rear end, which then adheres to a pressure plate and a support plate. After adhesion, the pressure plate is driven to clamp the bamboo filaments, and the clamping assembly returns to its initial position, allowing for cutting. After cutting, the pressure plate and support plate move the cut bamboo filaments to a collection trough for collection, ensuring stability during the cutting process and preventing tilting and unevenness.

Description

Technical Field

[0001] This utility model relates to the field of cutting snowflake-shaped bamboo strands, and in particular to a snowflake-shaped bamboo strand cutting and sorting device. Background Technology

[0002] Snowflake-shaped slub yarn is a special yarn with a unique snowflake-like appearance and slub texture. Through a special process, a three-dimensional texture similar to falling snowflakes is formed on the surface of the yarn. At the same time, combined with the thickness variation of slub yarn, the fabric has both a sense of layering and an artistic effect.

[0003] Existing snowflake-shaped slub yarn cutting devices typically create the slub effect during the spinning stage by controlling the feeding and drafting processes of the two raw materials. However, the feeding amount and drafting ratio of the decorative yarn and core yarn need to be precisely controlled; otherwise, uneven slub distribution and excessive feeding of the decorative yarn can lead to burrs, tilting, or unevenness on the cut surface. This not only affects the appearance of the filament but also causes problems such as entanglement and breakage in subsequent processing.

[0004] Therefore, it is necessary to provide a snowflake-shaped bamboo fiber cutting and sorting device to solve the above-mentioned technical problems. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First Embodiment

[0027] Please refer to the following: Figures 1-7 A snowflake-shaped bamboo filament cutting and sorting device includes a base 1. Two first vertical plates 2 are vertically arranged on both sides of the front end of the base 1. A rotating shaft 3 is rotatably connected between the two first vertical plates 2. A plurality of unwinding rollers 4 are fixedly connected to the surface of the rotating shaft 3. A guide assembly is arranged on the base 1 at the rear end of the unwinding rollers 4. A guide plate 11 is arranged on the base 1 at the rear end of the guide assembly. Two fourth vertical plates 13 are arranged on the base 1 at the rear end of the guide plate 11. A worktable 17 is arranged between the two fourth vertical plates 13. A cutting blade 16 for cutting flower-shaped bamboo filaments is vertically and flexibly arranged between the fourth vertical plates 13 at the front end of the worktable 17. A clamping assembly that can move from the front end to the rear end of the worktable 17 is arranged between the two fourth vertical plates 13.

[0028] The raw material containing snowflake-shaped bamboo strips is wound onto the unwinding roller 4, which drives the unwinding roller 4 to rotate, thereby unwinding the bamboo strips. During the unwinding process, the unwinding speed can be adjusted by controlling the rotation speed of the rotating shaft 3 according to the processing requirements.

[0029] The bamboo strands released from the unwinding roller 4 enter the guiding assembly, where they are guided in the correct direction and move along a predetermined path to the subsequent process. The guiding assembly ensures the bamboo strands remain stable during transport, preventing problems such as tangling and deviation.

[0030] The bamboo strands, after passing through the guide assembly, enter the guide plate 11. The guide plate 11 further guides and positions the bamboo strands, enabling them to accurately reach the front end of the workbench 17, preparing them for subsequent cutting operations. At the same time, the guide plate 11 also provides some support, preventing the bamboo strands from sagging or deforming during transmission.

[0031] When the bamboo strands reach the designated position at the front end of the worktable 17, the control system issues a command, and the lifting mechanism drives the cutter 16 to descend rapidly. The cutter 16 cuts the snowflake-shaped bamboo strands with a certain pressure and speed. After cutting, the lifting mechanism drives the cutter 16 to rise and return to the initial position, waiting for the next cutting operation.

[0032] After the cutter 16 cuts the bamboo strands, the drive mechanism of the clamping assembly activates, bringing the two clamping blocks closer together to clamp the cut bamboo strands. Then, the transmission mechanism moves the clamping assembly and the clamped bamboo strands from the front end to the rear end of the worktable 17. Upon reaching the designated position at the rear end of the worktable 17, the clamping blocks release, and the cut and arranged bamboo strands are placed on the worktable or proceed to the next processing step. Afterward, the clamping assembly returns to the front end of the worktable, ready for the next clamping and moving operation.

[0033] During operation, the raw material roll with snowflake-shaped bamboo strands is first placed on the unwinding roller 4. The bamboo strands pass through the guide assembly and guide plate 11 in sequence and then reach the front end of the worktable 17. The cutter 16 cuts the bamboo strands according to the set requirements. The clamping assembly clamps the cut bamboo strands and moves them to the rear end of the worktable 17 for sorting, thus completing the entire processing process.

[0034] Please refer to Figure 3 A motor 5 is horizontally arranged on one side of the first vertical plate 2. The output shaft of the motor 5 is fixedly connected to one end of the rotating shaft 3. Two third vertical plates 10 are arranged on the base 1 and at the rear end of the first vertical plate 2. A guide plate 11 is arranged between the two third vertical plates 10. The guide plate 11 has a plurality of limiting holes 12 for bamboo strips to pass through.

[0035] In this embodiment, when the motor 5 is started, the output shaft of the motor 5 begins to rotate, which drives the rotating shaft 3 to rotate through the connecting piece. The unwinding roller 4 on the surface of the rotating shaft 3 rotates accordingly, thereby realizing the unwinding of the snowflake-shaped bamboo strips.

[0036] Please refer to Figure 1 and Figure 2The guiding component includes a second vertical plate 6, which is disposed between the first vertical plate 2 and the third vertical plate 10. A fixed roller 9 is rotatably disposed between the two second vertical plates 6. A limiting roller 7, which is in contact with the fixed roller 9, is disposed between the two second vertical plates 6 and below the fixed roller 9. The surface of the limiting roller 7 is provided with a plurality of through grooves 8 through which bamboo strands can pass.

[0037] In this embodiment, when the bamboo strands reach the position of the limiting roller 7, they pass through the corresponding through grooves 8 on the surface of the limiting roller 7. Due to the constraint effect of the through grooves 8 on the bamboo strands, the bamboo strands are restricted to a specific path during transmission, avoiding problems such as deviation and entanglement. At the same time, the fixed roller 9 is fitted to the limiting roller 7. When the bamboo strands pass through the through grooves 8, the fixed roller 9 and the limiting roller 7 exert a certain pressure on the bamboo strands, which helps to maintain the tension stability of the bamboo strands and allows them to be transmitted forward more smoothly and orderly.

[0038] Please refer to Figure 5 A first placement plate 20 is provided between the two fourth vertical plates 13 and at the front end of the workbench 17. The surface of the first placement plate 20 has a plurality of placement slots 21 for placing bamboo strips. A fixing plate 19 for fixing snowflake-shaped bamboo strips is provided between the two fourth vertical plates 13 and on the first placement plate 20. The bottom of the fixing plate 19 has a plurality of protrusions 29 that are adapted to the placement slots 21. A first receiving slot 33 is provided on the side wall of one of the fourth vertical plates 13. A first electric telescopic rod 34 is vertically arranged in the first receiving slot 33. One end of the first electric telescopic rod 34 is fixedly connected to the fixing plate 19.

[0039] In this embodiment, the first electric telescopic rod 34 is activated by the control system, causing it to extend downwards and drive the fixing plate 19 to move downwards. As the fixing plate 19 descends, the protrusion at the bottom of the fixing plate 19 gradually inserts into the placement groove 21 on the first placement plate 20, pressing and fixing the bamboo strips placed in the groove. During the fixing process, the movement of the fixing plate 19 is closely observed to ensure that the protrusion 29 is accurately inserted into the placement groove 21 and that the pressure of the fixing plate 19 on the bamboo strips is moderate, avoiding damage to the bamboo strips due to excessive pressure or insecure fixing due to insufficient pressure.

[0040] Please refer to Figure 1 and Figure 5The clamping assembly includes two electric slide rails 22, a second placement plate 31, and a clamping plate 30. The two electric slide rails 22 are disposed on the side wall of a fourth vertical plate 13. Each electric slide rail 22 has a slider 23 slidably disposed on its surface. The second placement plate 31 is fixedly connected to one side of the slider 23 and slidably connected to the worktable 17. The clamping plate 30 is fixedly connected to the side wall of the slider 23 and is located above the second placement plate 31. The bottom of the clamping plate 30 is provided with a positioning plate 36 for fixing bamboo strips, which can be raised and lowered. The clamping plate 30 has an elongated groove, and several third electric telescopic rods 35 are vertically disposed in the elongated groove. The bottom ends of the several third electric telescopic rods 35 are fixedly connected to the positioning plate 36.

[0041] In this embodiment, after the clamping plate 30 and the positioning plate 36 are clamped, it is necessary to ensure that a section of the bamboo strip is left in front for subsequent clamping and tidying.

[0042] Place the prepared bamboo strips on the second placement plate 31, activate the third electric telescopic rod 35 to extend it downwards, causing the positioning plate 36 to descend. The bottom of the positioning plate 36 gradually contacts the bamboo strips, pressing and fixing the bamboo strips onto the second placement plate 31. Then, by controlling the electric slide rail 22, the positioning plate 36 and the clamping plate 30 are moved backwards to the distance to be cut, and then connected to subsequent processing.

[0043] Please refer to Figure 1 and Figure 2 A horizontal plate 14 is provided at the top of the two fourth vertical plates 13. A hydraulic cylinder 24 is vertically provided in the middle of the horizontal plate 14. A movable plate 15 is fixedly connected to the bottom end of the hydraulic cylinder 24. The cutter 16 is fixedly connected to the bottom of the movable plate 15.

[0044] In this embodiment, the control system controls the hydraulic cylinder 24 to descend, which drives the movable plate 15 and the cutter 16 to move downward, thereby cutting the bamboo strips.

[0045] Second Embodiment

[0046] Please refer to Figures 1-5 Based on the same concept as the first embodiment described above, drive grooves 32 are provided on both sides of the worktable 17. A sliding block 28 is slidably provided in each drive groove 32. A connecting plate 27 is fixedly connected to the surface of each of the two sliding blocks 28. A support plate 26 that fits against the worktable 17 is fixedly connected to the bottom between the two connecting plates 27. A pressure plate 25 is provided between the two connecting plates 27 and on the support plate 26. A plurality of collection grooves 18 corresponding to the unwinding roller 4 are provided at the rear end of the worktable 17. An ejection component is provided in each collection groove 18.

[0047] The drive groove 32 may be equipped with a lead screw assembly. By driving the lead screw to rotate, the sliding block 28 is moved along its length direction, so that the cut bamboo strips are moved into the collection groove 18 for sorting and collection. The collection groove 18 may be equipped with a winding device for winding the bamboo strips.

[0048] When the bamboo strips are moved to the pressure plate 25 by the clamping assembly, the pressure plate 25 is driven to descend and press the bamboo strips onto the support plate 26 for cutting. After cutting, the sliding block 28 is driven to move, which simultaneously drives the pressure plate 25 and the support plate 26 to slide along the surface of the worktable 17 until they move onto the collection tank 18. Then the pressure plate 25 is raised.

[0049] The working principle of the snowflake-shaped bamboo fiber cutting and sorting device provided by this utility model is as follows:

[0050] During operation, the raw material roll with snowflake-shaped bamboo strands is first placed on the unwinding roller 4. The bamboo strands pass through the guide assembly and guide plate 11 in sequence and reach the front end of the worktable 17. The clamping assembly pulls the bamboo strands to the appropriate position, and one end of the bamboo strands is attached to the rear end of the worktable 17 with the pressure plate 25 and support plate 26. After attachment, the pressure plate 25 is driven to clamp the bamboo strands, and the clamping assembly returns to the initial position, so that they can be cut. After cutting, the pressure plate 25 and support plate 26 drive the cut bamboo strands to the collection trough 18 for collection.
