[0008] The present invention is further configured such that guide grooves are provided on the outer walls of the multiple sets of guide rollers.
[0009] This design, by setting guide grooves on the outer wall of the guide roller, helps the guide roller provide smoother guidance during movement, reduces friction and unnecessary resistance, and improves processing accuracy and stability.
[0010] The present invention is further configured such that a positioning rod is provided on the inner top surface of the fixing sleeve, and a positioning groove is provided at the top end of the insertion rod.
[0011] The cooperation between the positioning rod and the positioning groove ensures that the insertion rod is accurately aligned during installation and disassembly, preventing the guide roller from shifting or misaligning, and ensuring the accuracy and stability of the equipment.
[0012] The present invention is further configured such that both the positioning rod and the positioning groove are polygonal and compatible.
[0013] The polygonal design makes the fit between the positioning rod and the positioning groove more secure, avoiding loosening during rotation or sliding, and improving the accuracy and stability during installation and disassembly.
[0014] The present invention is further configured such that all of the multiple sets of sliding rods are polygonal and slidably connected to the fixed sleeve.
[0015] The connection between the polygonal slide bar and the fixed sleeve can improve the stability and friction of sliding, making the slide bar move more smoothly, reducing wear and jamming, and extending the service life of the equipment.
[0016] The present invention is further configured such that the bottom surfaces of the multiple sets of abutting blocks are all arc-shaped.
[0017] The arc-shaped bottom surface of the contact block helps the guide roller to make better contact and slide during movement, reducing friction and wear, while avoiding instability caused by uneven contact.

[0022] (III) Beneficial Effects
[0023] Compared with the prior art, this utility model provides a yarn guide machine for processing polypropylene staple fibers, which has the following beneficial effects:
[0024] 1. The guide mechanism is powered by a motor and connected to the support base via a drive rod, allowing the guide mechanism to move along a predetermined track. This ensures that the guide roller and the limit plate work together, guaranteeing that the guide roller will not exceed the predetermined range during processing. The multiple motor installations ensure a stable power source, enabling the guide roller to work flexibly and stably. This not only improves the reliability of the equipment but also avoids affecting the processing quality of polypropylene staple fiber due to the guide roller moving too far or too little. The design of the guide mechanism simplifies operation, ensuring that the polypropylene staple fiber is always in the correct guiding state, thus improving processing accuracy and efficiency.
[0025] 2. The main benefit of the quick-release mechanism is the rapid disassembly and installation of the guide roller. When the guide roller needs to be disassembled, by pushing the sliding sleeve to slide on the limit rod and compressing the compression spring, the unlocking sleeve cooperates with multiple sets of abutment blocks, causing the guide roller to disengage from the slot, so that the insertion rod can be easily removed from the fixed sleeve. This design reduces the time for disassembly and installation, simplifies the operation process, improves the maintenance efficiency of the equipment, avoids the complicated disassembly steps that may occur under the traditional method, and ensures high efficiency in the maintenance and replacement of the guide roller.
[0026] 3. The design of the unlocking sleeve has unique advantages. Through the setting of the clearance groove, the unlocking sleeve can smoothly guide and release the restriction on multiple sets of abutment blocks, so that the guide roller can be easily disassembled and installed. The cooperation between the unlocking sleeve and the return spring further enhances the self-recovery capability of the device, ensuring that the guide roller can be quickly and accurately reinstalled. When the guide roller is disassembled, the unlocking sleeve effectively releases the fixation of the guide roller through the unlocking function, making the installation process simple and fast, reducing the labor intensity of operators, and improving the reliability of the equipment.

[0036] Please see Figures 1-5 A polypropylene staple fiber processing guide machine includes a support base 1, on which a guide mechanism is provided. The guide mechanism includes a mounting plate 2, a motor 3, a drive rod 4, a limiting plate 5, and a guide roller 6. The mounting plate 2 is fixed to the outer wall of the support base 1. Multiple sets of motors 3 are fixed to the outer wall of the support base 1. The drive rod 4 is installed at the output end of multiple sets of motors 3 and is rotatably connected to the support base 1. Two sets of limiting plates 5 are installed on the mounting plate 2. A quick-release mechanism is provided between the guide roller 6 and the drive rod 4. The quick-release mechanism includes a fixed sleeve 7, a sliding rod 8, a locking block 9, an insert rod 10, a locking groove 11, an abutment block 12, an arc-shaped plate 13, a return spring 14, a limiting rod 15, a sliding sleeve 16, a connecting plate 17, a compression spring 18, an unlocking sleeve 19, and an abutment surface 20. The fixed sleeve 7 is connected to the top of the drive rod 4. Multiple sets of sliding rods 8 slide on the outer wall of the fixed sleeve 7. A locking block 9 is installed at the bottom of the multiple sets of sliding rods 8. An insert rod 10 is fixed to one end of the guide roller 6 and inserted into the fixed sleeve 7. Multiple sets of locking grooves 11 are distributed on the outer wall of the insert rod 10. An abutment block 12 is installed at the top of the multiple sets of sliding rods 8. An arc-shaped plate 13 is installed at the top of the multiple sets of abutment blocks 12. Multiple sets of reset springs 14 are provided, with both ends connected to the outer wall of the fixed sleeve 7 and the inner wall of the multiple sets of arc-shaped plates 13, respectively.

An unlocking sleeve 19 is installed on the top surface of the sliding sleeve 16, and an abutment surface 20 is located on the outer side of the unlocking sleeve 19.
[0037] The outer walls of multiple sets of guide rollers 6 are all provided with guide grooves 21.
[0038] By setting guide grooves 21 on the outer wall of the guide roller 6, the guide roller is ensured to maintain a stable trajectory during movement, which reduces friction and improves the guiding effect, thereby improving processing accuracy and equipment stability.
[0039] The top surface of the fixed sleeve 7 is provided with a positioning rod 22, and the top end of the insertion rod 10 is provided with a positioning groove 23.
[0040] The cooperation between the positioning rod 22 and the positioning groove 23 ensures that the insertion rod 10 can be accurately aligned during installation and disassembly, thereby avoiding offset or misalignment and ensuring the stability and precision of the overall structure.
[0041] Both the positioning rod 22 and the positioning groove 23 are polygonal and compatible.
[0042] The polygonal design enhances the tightness of the fit between the positioning rod 22 and the positioning groove 23, preventing loosening during rotation or sliding, thereby ensuring the robustness and stability of the equipment.
[0043] All sets of slide rods 8 are configured as polygons that are slidably connected to the fixed sleeves 7.
[0044] The sliding connection between the polygonal slide bar 8 and the fixed sleeve 7 ensures smooth sliding, reduces wear and jamming, and improves sliding stability and durability.
[0045] The bottom surfaces of multiple sets of abutment blocks 12 are all set to be arc-shaped.
[0046] The arc-shaped abutment block 12 has a bottom surface that can better contact the guide roller, reducing the contact area, thereby reducing friction and improving sliding performance and processing stability.
[0047] The unlocking sleeve 19 has a clearance groove 24. Multiple clearance grooves 24 are distributed on the unlocking sleeve 19, and the width of each clearance groove 24 is greater than that of the slide bar 8.
[0048] The design of the recess 24 allows the slide bar 8 to slide freely during the unlocking process. The width of the recess 24, which is greater than that of the slide bar 8, ensures sufficient room for movement and avoids jamming, thus making the unlocking process smoother and more efficient.
[0049] A push spring 25 is installed on the top surface of the inner sleeve 7. Multiple sets of push springs 25 are provided, and a top ring 26 is installed at the bottom end.
[0050] The push spring 25 provides continuous restoring force, helping the guide roller to quickly return to its original position after installation or removal, while the top ring 26 ensures even pressure distribution, enhancing the stability of the overall structure and extending the service life of the equipment.
[0051] In this embodiment, the motor 3 transmits power through the drive rod 4. The motor 3 is fixed at multiple positions on the outer wall of the support base 1, providing a continuous power source. When the motor 3 starts, the drive rod 4 begins to rotate. The drive rod 4 is rotatably connected to the support base 1, allowing the guide roller 6 to move along a predetermined track. The guide roller 6 cooperates with the limiting plate 5. The limiting function of the limiting plate 5 ensures that the movement of the guide roller 6 will not exceed the predetermined range. This ensures stability and safety during operation, avoiding any impact on the processing quality of polypropylene staple fiber due to the guide roller 6 moving too far or too little. Driven by motor 3, the guide fiber mechanism can be flexibly adjusted to achieve the correct guidance of polypropylene staple fiber. When the guide roller 6 needs to be disassembled, the sliding sleeve 16 is pushed to slide along multiple sets of limit rods 15 and squeeze the compression spring 18. The sliding sleeve 16 pushes the unlocking sleeve 19 to move and contacts multiple sets of abutment blocks 12 through the abutment surface 20, guiding the abutment blocks 12 to move outward. The abutment blocks 12 drive the arc plate 13 to stretch multiple sets of reset springs 14 and at the same time pull the locking block 9 outward through the sliding rod 8 to disengage from the locking groove 11, thereby releasing the locking of the insertion rod 10. Then, the top is pushed by multiple sets of push springs 25. Ring 26 pushes the insertion rod 10 to disengage from the fixing sleeve 7, completing the disassembly of the guide roller 6. When it needs to be installed, the positioning groove 23 on the insertion rod 10 is aligned with the positioning rod 22 and inserted. The push on the sliding sleeve 16 is released, and the elastic reset of the compression spring 18 pushes the sliding sleeve 16 and the unlocking sleeve 19. The unlocking sleeve 19 releases the restriction on the multiple sets of abutment blocks 12. The elastic reset of the multiple sets of reset springs 14 pulls the arc plate 13 and the abutment block 12. The abutment block 12 pushes the locking block 9 through the sliding rod 8 to engage in the locking groove 11, fixing the insertion rod 10 and completing the installation of the guide roller 6.
[0052] In summary, during the use or operation of the entire equipment: Motor 3 transmits power through drive rod 4. Motor 3 is fixed at multiple positions on the outer wall of support base 1, providing a continuous power source. When motor 3 starts, drive rod 4 begins to rotate. Drive rod 4 is rotatably connected to support base 1, allowing the guide roller 6 to move along a predetermined track. The guide roller 6 cooperates with limit plate 5. The limiting function set by limit plate 5 ensures that the movement of guide roller 6 will not exceed the predetermined range. This ensures stability and safety during operation, avoiding impact on the processing quality of polypropylene staple fiber due to excessive or insufficient movement of guide roller 6. Driven by motor 3, the guide fiber mechanism can be flexibly adjusted to achieve the correct guidance of polypropylene staple fiber. When the guide roller 6 needs to be disassembled, the sliding sleeve 16 is pushed to slide along multiple sets of limit rods 15 and squeeze the compression spring 18. The sliding sleeve 16 pushes the unlocking sleeve 19 to move and contacts multiple sets of abutment blocks 12 through the abutment surface 20, guiding the abutment blocks 12 to move outward. The abutment blocks 12 drive the arc plate 13 to stretch multiple sets of reset springs 14 and at the same time pull the locking block 9 outward through the sliding rod 8 to disengage from the locking groove 11, thereby releasing the locking of the insertion rod 10. Then, the top is pushed by multiple sets of push springs 25. Ring 26 pushes the insertion rod 10 to disengage from the fixing sleeve 7, completing the disassembly of the guide roller 6. When it needs to be installed, the positioning groove 23 on the insertion rod 10 is aligned with the positioning rod 22 and inserted. The push on the sliding sleeve 16 is released, and the elastic reset of the compression spring 18 pushes the sliding sleeve 16 and the unlocking sleeve 19.
