Description

Technical Field

[0001] This utility model relates to the technical field of aluminum rod spindles for spinning machines, specifically to an aluminum rod spindle for a spinning machine with a yarn cutter securely installed. Background Technology

[0002] The aluminum spindle is one of the main components of the twisting and winding mechanism on a spinning frame. Its main components include the spindle rod, spindle disc, spindle core, spindle feet, and spindle hook. The spindle rod, as a high-speed rotating shaft, is usually made of bearing steel and is used to engage with the bobbin's opening and press the spindle disc. The part where it engages with the roller bearing is cylindrical. The spindle disc, made of cast iron, is tightly fitted around the middle of the spindle rod and is the spindle's transmission component. The yarn cutter is a device used in the automatic doffing process. Its main function is to cut the yarn during doffing, ensuring a smooth doffing process. The yarn cutter is usually used in conjunction with the spindle, using mechanical or electronic means to cut and clamp the yarn, thereby reducing yarn breakage and yarn retraction during doffing.

[0003] The existing yarn cutter on aluminum spindles is usually installed on top of the spindle disc with an interference fit. The installation method between the yarn cutter and the spindle disc is only based on the interference fit technology, which results in poor installation stability. After a period of use, the blades of the yarn cutter will become dull, which will cause the yarn cutter to malfunction and the yarn head retention rate to decrease. It is necessary to replace the entire yarn cutter or the entire spindle, which increases the cost. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 5As shown in this embodiment, a spinning machine aluminum spindle with a securely mounted yarn cutter includes a spindle 1. A spindle disc 2 is mounted on the outer side of the middle part of the spindle 1. A mounting platform 3 is provided at the top of the spindle disc 2. A yarn cutter body 4 is mounted on the spindle disc 2 corresponding to the mounting platform 3. Positioning rods 5 are slidably mounted in a ring array around the central axis of the spindle disc 2 at the position corresponding to the mounting platform 3 at the top of the spindle disc 2. The yarn cutter body 4 includes a yarn cutter seat 6 and a blade 7. A storage hole 8 is provided at the bottom end of the yarn cutter seat 6. The blade 7 is fitted onto the lower end of the yarn cutter seat 6 at the position corresponding to the storage hole 8. The yarn cutter seat 6 and the blade 7 are detachably connected. The inner ring of the yarn cutter seat 6 is arranged in a ring array around the central axis of the yarn cutter seat 6 at the position corresponding to the positioning rods 5. The device has a positioning hole 9, which is slidably inserted into the positioning rod 5. After assembling the spindle rod 1 and the spindle plate 2, the blade 7 is fitted into the storage hole 8 at the bottom of the yarn cutter seat 6. Then, the yarn cutter body 4 is fitted onto the outside of the mounting platform 3 at the top of the spindle plate 2. The positioning rod 5 is inserted into the positioning hole 9 in the inner ring of the yarn cutter seat 6 to control the yarn cutter body 4 to be stably fixed on the spindle plate 2, thereby improving the installation stability of the yarn cutter body 4. By sliding the positioning rod 5 out of the positioning hole 9 in the inner ring of the yarn cutter seat 6, the yarn cutter body 4 can be removed from the spindle plate 2. Then, the blade 7 can be taken out separately from the storage hole 8 at the bottom of the yarn cutter seat 6. A new blade 7 can be replaced and installed in the storage hole 8 at the bottom of the yarn cutter seat 6, which facilitates the replacement of the blade 7 and reduces production costs.

[0023] like Figures 1 to 5 As shown, the top of the spindle 2 is provided with a storage groove 10 arranged in a ring array with the central axis of the spindle 2 as the axis corresponding to the position of the mounting platform 3. The positioning rod 5 is slidably installed inside the storage groove 10. A first spring 11 is fixedly installed at one end of the storage groove 10. The end of the first spring 11 away from the positioning rod 5 is fixedly connected to the inner wall of the end of the storage groove 10 corresponding to the spindle 2.

[0024] When the yarn cutter body 4 is placed on the outside of the mounting platform 3 at the top of the spindle 2, the positioning rod 5 can be pushed by the first spring 11 to insert into the positioning hole 9 of the inner ring of the yarn cutter seat 6, which is used to position and connect the positioning rod 5 to the positioning hole 9.

[0025] like Figures 1 to 5 As shown, the storage groove 10 has a first chamfer 12 at the end away from the first spring 11.

[0026] When the positioning rod 5 is inserted into the positioning hole 9, the first chamfer 12 facilitates the positioning and insertion between the positioning rod 5 and the positioning hole 9.

[0027] like Figures 1 to 5As shown, the top of the spindle 2 has sliding holes 13 arranged in a ring around the central axis of the spindle 2. The sliding holes 13 are located above the receiving groove 10. A pressure rod 14 is slidably installed inside the sliding holes 13. The bottom end of the pressure rod 14 has an inclination angle 15. The outer side of the top of the positioning rod 5 has a pressing slope 16. The pressing slope 16 is pressed and contacted with the inclination angle 15. A pressure ring 17 is fixedly installed on the top of the four pressure rods 14. The pressure ring 17 passes through the spindle rod 1.

[0028] Pressing the pressure ring 17 causes the pressure rod 14 to slide inside the sliding hole 13. The pressure rod 14, with its bottom angle 15, presses against the top of the positioning rod 5, causing the positioning rod 5 to slide inside the storage groove 10.

[0029] like Figures 1 to 5 As shown, the top of the spindle 2 is fixedly installed with limit rods 18 in a ring array around the central axis of the spindle 2. The pressure ring 17 has limit holes 19 at the positions of the limit rods 18. The limit holes 19 are slidably connected to the limit rods 18. A second spring 20 is sleeved on the outer side of the top of the limit rod 18. One end of the second spring 20 is fixedly connected to the top of the limit rod 18, and the other end of the second spring 20 is fixedly connected to the upper surface of the pressure ring 17.

[0030] When the pressure ring 17 is pressed down along the limit rod 18, the second spring 20 is in a stretched state. When the pressure ring 17 is released, the second spring 20 pulls the pressure ring 17, causing the pressure ring 17 to slide up along the trajectory of the limit rod 18. The pressure rod 14 is released to squeeze the positioning rod 5, thus resetting the pressure ring 17.

[0031] like Figures 1 to 5 As shown, the bottom end of the yarn cutter seat 6 is provided with insertion holes 21 arranged in a ring array above the storage hole 8 with the central axis of the yarn cutter seat 6 as the axis. The upper surface of the blade 7 is fixedly installed with insertion rods 22 arranged in a ring array with the central axis of the blade 7 as the axis. The insertion rods 22 are slidably inserted into the insertion holes 21.

[0032] When the insert rod 22 on the blade 7 is inserted into the insertion hole 21 at the bottom of the yarn cutter seat 6, the blade 7 and the yarn cutter seat 6 can be relatively fixed to prevent relative rotation between the blade 7 and the yarn cutter seat 6 during the rotation of the aluminum rod spindle.

[0033] like Figures 1 to 5 As shown, the top end of the insertion rod 22 is provided with a second chamfer 23.

[0034] This makes it easy to insert the insert rod 22 on the blade 7 into the insertion hole 21 at the bottom of the yarn cutter seat 6.

[0035] This utility model provides an aluminum spindle for a spinning machine with a securely mounted yarn cutter. The specific working principle is as follows:

[0036] When using the device, after assembling the spindle 1 and the spindle disc 2, the blade 7 is fitted into the storage hole 8 at the bottom of the yarn cutter seat 6, and the insertion rod 22 on the blade 7 is inserted into the insertion hole 21 at the bottom of the yarn cutter seat 6 to assemble the blade 7 and the yarn cutter seat 6 into the yarn cutter body 4. Pressing the pressure ring 17 causes the pressure rod 14 to slide inside the sliding hole 13. Under the pressure of the inclined surface 16 at the top of the positioning rod 5 by the inclination angle 15 at the bottom of the pressure rod 14, the positioning rod 5 will slide into the storage groove 10. At this time, the first spring 11 is in a compressed state. The second spring 20 is in the stretched state. Then, the yarn cutter body 4 is placed on the outside of the mounting platform 3 at the top of the spindle 2. The pressure ring 17 is removed. The pressure ring 17 is pulled by the second spring 20 and will slide upward along the trajectory of the limit rod 18. The pressure rod 14 is removed and the positioning rod 5 is squeezed. The positioning rod 5 is pushed by the first spring 11 and will be inserted into the positioning hole 9 of the inner ring of the yarn cutter seat 6. This is used to control the yarn cutter body 4 to be stably fixed on the spindle 2 and improve the installation stability of the yarn cutter body 4.

[0037] When replacing the blade 7, pressing the pressure ring 17 causes the pressure rod 14 to slide inside the sliding hole 13. The pressure rod 14, with its bottom angle 15, presses against the top of the positioning rod 5, causing the positioning rod 5 to slide into the storage groove 10. The positioning rod 5 is then inserted into the positioning hole 9 of the inner ring of the yarn cutter seat 6, allowing the yarn cutter body 4 to be removed from the spindle 2. The blade 7 can then be removed separately from the storage hole 8 at the bottom of the yarn cutter seat 6. A new blade 7 can then be installed in the storage hole 8 at the bottom of the yarn cutter seat 6, facilitating the replacement of the blade 7 and reducing production costs.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
