Description

Technical Field

[0001] This utility model belongs to the technical field of twisting machines, specifically a doffing machine suitable for twisting machines. Background Technology

[0002] A twisting machine is a device that twists multiple yarns into a ply, improving the yarn's strength and abrasion resistance. Its core lies in the rotation of the twisting spindle, which causes the yarns to intertwine and form a stable structure. After twisting, the doffing device removes the twisted ply from the twisting mechanism and winds it onto a bobbin or package for subsequent processes. The efficiency and quality of doffing directly affect the final spindle's formation and subsequent use. Twisting machines are widely used in the textile and rope industries to produce various yarns and ropes. Traditional old-style twisting machines mostly use manual doffing, which requires considerable force to remove the yarn from the bobbin, resulting in high workload and low production efficiency. Therefore, improvements are needed to address these issues. Utility Model Content

Detailed Implementation

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0011] Depend on Figures 1 to 3The present invention includes a connecting turntable 1, a connecting shaft 2 fixedly installed at the center of the bottom of the connecting turntable 1, the connecting shaft 2 being rotatably connected to a twisting machine and adjusted for rotation by a transmission structure on the twisting machine, an insert shaft 3 fixedly installed at the center of the top of the connecting turntable 1, a vertical through groove 4 formed in the center of the insert shaft 3, a threaded shaft 5 rotatably connected between the interior of the vertical through groove 4 and the top of the connecting turntable 1, a slider 6 slidably installed inside the vertical through groove 4 being threadedly connected to the surface of the threaded shaft 5, and a dragging sleeve 7 movably sleeved on the surface of the insert shaft 3, the slider 6... Both ends are fixedly connected to the drag sleeve 7. The top of the drag sleeve 7 is provided with a yarn roll 8 that fits onto the surface of the insert shaft 3. There are three fixing parts 9 between the drag sleeve 7 and the connecting turntable 1. All three fixing parts 9 abut against the inner wall of the yarn roll 8. The middle part of the connecting turntable 1 has an inner cavity 18. The inside of the inner cavity 18 is equipped with a forward and reverse motor 19. The bottom of the threaded shaft 5 extends through the inner cavity 18 and is fixedly connected to the output end of the forward and reverse motor 19, so that the yarn roll 8 can be effectively disassembled and assembled and the yarn can be unloaded.

[0012] Each of the three fasteners 9 includes a through groove 11. The three through grooves 11 are circumferentially and equidistantly formed on the drag sleeve 7 and penetrate through the drag sleeve 7. A slide rod 12 is fixedly installed on the upper part of each of the three through grooves 11. A slider 2 13 is movably sleeved on the surface of each of the three slide rods 12, and a spring 14 is sleeved on the surface of each of the three slide rods 12. The two ends of the spring 14 are fixedly connected to the side wall of the slider 2 13 and the through groove 11, respectively. An inner support clamping block 15 is fixedly installed on the top of each of the three slider 2 13. The three inner support clamping blocks 15 are located above the drag sleeve 7 and abut against and clamp the inner wall of the yarn roll 8, thereby fixing the installed yarn roll 8.

[0013] Each of the three sliders 13 has a pressure block 16 fixedly installed at the bottom inside the through groove 11. The bottom of each pressure block 16 has a pressure slope. Three extrusion blocks 17 are fixedly installed at equal intervals in a ring on the top of the drag sleeve 7. The three extrusion blocks 17 are aligned with the three through grooves 11 and are located inside the three through grooves 11 respectively. The top of each of the three extrusion blocks 17 has an extrusion slope. The three extrusion slopes are aligned with the three pressure slopes respectively and contact and extrude the three pressure slopes respectively, thereby stretching the spring 14, so as to effectively install and fix the yarn roll 8.

[0014] Specifically, as shown in the attached figure, when the twisting machine starts, it drives the connecting shaft 2 through the transmission structure on it to rotate the connecting turntable 1. The rotation of the connecting turntable 1 will drive the insert shaft 3 and the drag sleeve 7 to rotate. At the same time, the rotation of the connecting turntable 1 will drive the yarn roll 8 to rotate through the drag sleeve 7 and the three inner support clamping blocks 15 that clamp and fix the yarn roll 8, so as to wind and rewind the yarn. After the yarn roll 8 is finished rolling, the connecting turntable 1 stops rotating. Then, the forward and reverse motor 19 is started to drive the threaded shaft 5 to rotate. The rotation of the threaded shaft 5 will cause the slider 6 to move upward on its surface, which will drive the dragging sleeve 7 and the yarn roll 8 to move upward. The upward movement of the dragging sleeve 7 will drive the pressure block 16 to move upward and separate from the squeezing block 17, thereby separating the pressure slope from the squeezing slope. Then, the elastic restoring force of the spring 14 will cause the slider 13 to slide on the slide rod 12, which will drive the inner support clamping block 15 and the pressure block 16 to move, thereby separating all three inner support clamping blocks 15 from the yarn roll 8. Finally, when the dragging sleeve 7 moves to the upper part of the insertion shaft 3, it stops. At this time, the yarn roll 8 can be unloaded and disassembled. Next, a brand new yarn roll 8 is placed on top of the drag sleeve 7, and the insert shaft 3 and the three inner support clamping blocks 15 are all located inside the brand new yarn roll 8. Then, the forward and reverse motor 19 is started in reverse, so that the drag sleeve 7 moves down. Then, through the contact of the three pressure slopes and the three extrusion slopes, the three inner support clamping blocks 15 will abut and fix the inside of the yarn roll 8, thus maintaining the stability and firmness of the yarn roll 8 installation.

[0015] This doffing machine features an automatic lifting doffing structure and an automatic yarn roll fixing structure. The automatic lifting doffing structure allows for convenient and effective disassembly and assembly of the yarn roll, thereby reducing the intensity of the doffing work and improving production efficiency. The automatic yarn roll fixing structure effectively secures the installed yarn roll before winding, thus effectively improving the stability of winding. At the same time, this doffing machine has a simple structural design, is easy and convenient to use, and has stable and reliable adjustment. Its performance can meet the doffing requirements of twisting machines.
