Description

Technical Field

[0001] This utility model belongs to the technical field of cotton yarn processing equipment, and in particular relates to a twisting device for medical cotton yarn. Background Technology

[0002] Currently, in the production of medical cotton yarn, existing twisting devices can twist multiple strands of yarn together to form cotton yarn, and can also wind and pull the cotton yarn formed after twisting. For example, the utility model patent with publication number CN223176296U in the existing patent can achieve the above functions.

[0003] However, in the prior art, since medical cotton yarn is sometimes made of yarns with different numbers of strands twisted together, the above-mentioned utility model is not convenient to flexibly increase or decrease the number of cotton yarn rods on the turntable disclosed in its use, and the position of the cotton yarn rods cannot be adjusted along the circumference of the turntable. Therefore, it is inconvenient to use. Thus, there are still shortcomings and deficiencies in the prior art. Utility Model Content

[0004] The purpose of this invention is to provide a twisting device for medical cotton yarn to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: A twisting device for medical cotton yarn includes a horizontally arranged base. A winding mechanism, a yarn bundling mechanism, and a take-up mechanism are sequentially mounted on the top surface of the base. The winding mechanism includes a support frame mounted on the base. A horizontally distributed rotating shaft is rotatably connected to the support frame. A drive motor is driven to the end of the rotating shaft away from the yarn bundling mechanism. The other end of the rotating shaft passes through the support frame and is coaxially fixed to a winding turntable. Multiple rotatable bobbins that can move circumferentially along the winding turntable are detachably mounted on the outer periphery of the side of the winding turntable away from the rotating shaft. The axial line of each bobbin is parallel to the axial line of the winding turntable. A connecting shaft is coaxially fixed on the side of the winding turntable away from the rotating shaft. A detachable disc is coaxially fitted on the end of the connecting shaft away from the winding turntable. The disc has multiple wire through holes, the same number as the number of bobbins, and equidistantly distributed along the circumference of the disc. The axial lines of the wire through holes are all parallel to the axial line of the disc.

[0006] Furthermore, the winding turntable has an annular groove coaxially formed on the side away from the rotating shaft. The two walls of the annular groove each have a groove structure forming a slide rail along the circumference of the groove. Multiple movable plates, equal in number to the number of bobbins, are slidably connected within the slide rail. Each movable plate is radially parallel to the winding turntable, and each movable plate is equipped with a first threaded rod parallel to the connecting shaft. The end of the first threaded rod away from the movable plate passes through the slide rail and is detachably mounted coaxially to a rotatable bobbin. A first locking sleeve is fitted onto the first threaded rod located between the bobbin and the winding turntable. The winding turntable has a notch on the side away from the rotating shaft, corresponding to the position of the slide rail and adapted to the movable plate.

[0007] Furthermore, a baffle is coaxially fixed to the end of the first threaded rod away from the movable plate, and a threaded shaft is coaxially fixed to the side of the baffle away from the first threaded rod. The diameter of the threaded shaft is smaller than the diameter of the baffle. The bobbins are slidably sleeved on the threaded shafts, and the inner diameter of the bobbins is smaller than the diameter of the baffles. Limit sleeves are fitted on the threaded shafts located outside the bobbins.

[0008] Furthermore, the outer periphery of the winding turntable away from the axis of rotation is marked with several scale lines that are equidistantly distributed along the circumference of the winding turntable.

[0009] Furthermore, a second threaded rod is coaxially fixed at the end of the connecting shaft away from the winding turntable. The diameter of the second threaded rod is smaller than the diameter of the connecting shaft. The diameter of the central hole of the disc is smaller than the diameter of the connecting shaft. The disc is slidably sleeved on the second threaded rod. A second locking sleeve is also fitted on the second threaded rod located on the side of the disc away from the connecting shaft.

[0010] Furthermore, the wire harness mechanism includes a wire harness coil mounted on a base and arranged coaxially with the winding turntable.

[0011] The beneficial effects of this utility model by adopting the above technical solution are as follows: This invention, based on existing base, winding mechanism, yarn bundling mechanism, and take-up mechanism, detachably mounts multiple spools that can rotate and move circumferentially along the winding turntable on its outer periphery away from the rotating shaft. This allows for flexible adjustment of the number of spools on the winding turntable according to the different ply counts of the yarn. Furthermore, the spools' positions can be adjusted circumferentially to ensure equidistant distribution. Additionally, the detachable disc allows for replacement with a suitable disc on the connecting shaft to match the number of wire through holes on the disc with the yarn ply count, facilitating use. In summary, this invention is applicable to twisting yarns of different ply counts together to form cotton yarn. Attached Figure Description

[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0015] like Figures 1 to 7 As shown, this utility model provides a twisting device for medical cotton yarn, including a horizontally arranged base 4. A winding mechanism 2, a yarn-binding mechanism 1, and a take-up mechanism 3 are sequentially mounted on the top surface of the base 4, arranged opposite to each other. Specifically, the base 4, winding mechanism 2, yarn-binding mechanism 1, and take-up mechanism 3 are used in the same way as existing technologies. That is, the winding mechanism 2 can twist multiple strands of yarn to form cotton yarn, and then the twisted cotton yarn is passed through the yarn-binding mechanism 1 and taken up and pulled by the take-up mechanism 3. In addition, this utility model also includes a controller with a control panel (not shown in the figure). The controller is signal-connected to the winding mechanism 2 and the take-up mechanism 3. During use, the operating parameters and other data of each mechanism can be adjusted through the control panel.

[0016] The specific configuration of the winding mechanism 2 is as follows: The winding mechanism 2 includes a support frame 201 mounted on the base 4, and a first reinforcing rib 220 is installed between the support frame 201 and the base 4; a horizontally distributed rotating shaft 202 is rotatably connected to the support frame 201, and a drive motor 203 is drivenly connected to one end of the rotating shaft 202 away from the wire harness mechanism 1, and the drive motor 203 has its own power supply and start / stop switch; the other end of the rotating shaft 202 passes through the support frame 201 and is coaxially fixed to a winding turntable 204, and multiple spools that can rotate and move circumferentially along the winding turntable 204 are detachably installed on the outer periphery of the side of the winding turntable 204 away from the rotating shaft 202. 205. Each bobbin 205 has yarn wound on it, and the yarn can be unwound by rotating the bobbin 205. The axial line of each bobbin 205 is parallel to the axial line of the winding turntable 204. Specifically, in use, since the bobbins 205 can be disassembled, the number of bobbins 205 on the winding turntable 204 can be flexibly increased or decreased according to the number of yarn strands. After increasing or decreasing the number of bobbins 205, since the bobbins 205 can move along the circumference of the winding turntable 204, the position of the bobbins 205 can also be adjusted along the circumference of the winding turntable 204 so that multiple bobbins 205 are evenly distributed along the circumference of the winding turntable 204.

[0017] Based on this, a connecting shaft 206 is coaxially fixed on the side of the winding turntable 204 away from the rotating shaft 202. A detachable disc 207 is coaxially fitted on the end of the connecting shaft 206 away from the winding turntable 204. The disc 207 has multiple wire through holes 208, the same number as the yarn spools 205, and equidistantly distributed along the circumference of the disc 207. The axial lines of the wire through holes 208 are all parallel to the axial line of the disc 207. Specifically, multiple discs 207 can be configured, and the number of wire through holes 208 on each disc 207 is different. Since the disc 207 is detachable, a suitable disc 207 can be replaced on the connecting shaft 206 according to the different number of yarns, so that the number of wire through holes 208 on the disc 207 is equal to the number of yarns, which is convenient for use. In general, this utility model can be applied to twisting yarns of different numbers of yarns together to form cotton yarn.

[0018] Specifically, in use, the yarn on the bobbin 205 can be passed through the wire through hole 208 and then through the disc 207. Then, the free ends of the multiple strands of yarn are pinched together. At this time, when the drive motor 203 is started, the multiple strands of yarn can be twisted together. Then, the cotton yarn formed after twisting is passed through the yarn bundling mechanism 1, and the winding mechanism 3 winds up and pulls the cotton yarn. In addition, in use, it is also possible to choose whether to install a cleaning mechanism that can be used to clean dust on cotton yarn in the prior art according to one's own needs.

[0019] The specific configuration of the spool 205, which can be detached from the winding turntable 204, rotate, and move circumferentially around the winding turntable 204, is as follows: Figures 2 to 7 As shown, an annular groove is coaxially formed on the side of the winding turntable 204 away from the rotating shaft 202. Grooves forming slides 209 are formed on both walls of the annular groove along its circumference. Specifically,... Figure 7 For example, the vertical cross-section of the slide 209 is an inverted T-shaped structure; multiple movable plates 210, equal in number to the number of spools 205, are slidably connected inside the slide 209. Each movable plate 210 is radially parallel to the winding turntable 204, and each movable plate 210 is equipped with a first threaded rod 211 arranged parallel to the connecting shaft 206, forming an inverted T-shaped movable frame adapted to the slide 209. In use, the inverted T-shaped movable frame can move circumferentially along the winding turntable 204 via the slide 209. The end of the first threaded rod 211 away from the movable plate 210 passes through the slide 209 and is detachably mounted coaxially to a rotatable spool 205, located between the spool 205 and the winding turntable 204. Each of the first threaded rods 211 between the turntables 204 is fitted with a first locking sleeve 212. The outer diameter of the first locking sleeve 212 is larger than the groove size of the annular groove. Specifically, in use, when the position of the inverted T-shaped movable frame is adjusted along the circumference of the winding turntable 204, the position of the bobbin 205 can be adjusted simultaneously. After adjusting the position of the inverted T-shaped movable frame, the first locking sleeve 212 is rotated on the first threaded rod 211 until the first locking sleeve 212 is pressed against the winding turntable 204. This fixes the position of the inverted T-shaped movable frame on the winding turntable 204, thereby fixing the bobbin 205 on the winding turntable 204 when the position of the bobbin 205 is adjusted.

[0020] Secondly, a notch 213 is provided on the side of the winding turntable 204 away from the rotating shaft 202, which is opposite to the position of the slide 209 and is adapted to the movable plate 210. Specifically, when adjusting the position of the inverted T-shaped movable frame along the circumference of the winding turntable 204, the inverted T-shaped movable frame can be removed when the movable plate 210 moves to the position of the notch 213. Similarly, the inverted T-shaped movable frame can also be installed on the winding turntable 204 through the notch 213. In this way, the number of yarn spools 205 can be flexibly increased or decreased on the winding turntable 204 according to the different number of yarns.

[0021] The specific configuration of the spool 205 being detachable from the first threaded rod 211 is as follows: Figure 2 , Figure 4 and Figure 5As shown, a baffle 214 is coaxially fixed to the end of the first threaded rod 211 away from the movable plate 210. A threaded shaft 215 is coaxially fixed to the side of the baffle 214 away from the first threaded rod 211. The diameter of the threaded shaft 215 is smaller than the diameter of the baffle 214, thus forming a blocking structure at the connection point between the threaded shaft 215 and the baffle 214. The spools 205 are slidably sleeved on the threaded shafts 215, meaning the spools 205 can rotate around the threaded shafts 215. Furthermore, the inner diameter of the spools 205 is smaller than the diameter of the baffles 214, and the area outside the spools 205... Each threaded shaft 215 is fitted with a limiting sleeve 216, the outer diameter of which is larger than the inner diameter of the spool 205. Specifically, the spool 205 can be configured as an I-beam reel drum, and there is a gap between the two ends of the spool 205 and the limiting sleeve 216 or the baffle 214 to avoid affecting the rotation of the spool 205 around the threaded shaft 215. In use, the axial movement of the spool 205 can be restricted on the threaded shaft 215 by the cooperation of the baffle 214 and the limiting sleeve 216. After removing the limiting sleeve 216, a new spool 205 can be replaced on the threaded shaft 215.

[0022] Furthermore, such as Figure 6 As shown, the outer periphery of the winding turntable 204 away from the rotating shaft 202 is marked with several scale lines 217 that are equidistantly distributed along the circumference of the winding turntable 204. Specifically, the scale lines 217 are also marked with angle values, which are not shown in the figure. In use, since this utility model is not a precision device, the scale lines 217 can be used as a reference to adjust the position of the inverted T-shaped movable frame along the circumference of the winding turntable 204.

[0023] The specific arrangement of making the disc 207 detachable from the connecting shaft 206 is as follows: Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7As shown, a second threaded rod 218 is coaxially fixed to the end of the connecting shaft 206 away from the winding turntable 204. The diameter of the second threaded rod 218 is smaller than the shaft diameter of the connecting shaft 206, thus forming a blocking structure at the connection position between the second threaded rod 218 and the connecting shaft 206. The diameter of the central hole of the disc 207 is smaller than the shaft diameter of the connecting shaft 206, and the disc 207 is slidably sleeved on the second threaded rod 218. A second locking sleeve 219 is also fitted on the second threaded rod 218 on the side of the disc 207 away from the connecting shaft 206. The outer diameter of the second locking sleeve 219 is larger than the inner diameter of the disc 207. Specifically, in use... When the disc 207 is fitted onto the second threaded rod 218, by rotating the disc 207, the multiple wire through holes 208 on the disc 207 can be aligned with the positions of the multiple wire spools 205. Then, by rotating the second locking sleeve 219 on the second threaded rod 218, until both sides of the disc 207 are pressed against the connecting shaft 206 and the second locking sleeve 219 respectively, the disc 207 can be fixed on the connecting shaft 206. By rotating the second locking sleeve 219 in the opposite direction, the disc 207 can be removed after the second locking sleeve 219 is removed. This makes it easy to replace the disc 207 on the connecting shaft 206.

[0024] The specific configuration of the wire harness mechanism 1 is as follows: Figure 1 As shown, the yarn binding mechanism 1 includes a yarn binding coil 11 mounted on the base 4 and coaxially arranged with the winding turntable 204. Specifically, a vertically distributed support plate 12 is installed on the top surface of the base 4, and a second reinforcing rib plate 13 is installed between the support plate 12 and the base 4. The yarn binding coil 11 is installed at the top of the support plate 12. In use, after the multi-strand yarn is twisted and combined by the winding mechanism 2, it can pass through the central through hole of the yarn binding coil 11, and then the winding mechanism 3 can wind up the yarn formed after twisting.
