Description

Technical Field

[0001] This invention relates to an automatic assembly and disassembly device and method for the spindle of a glass fiber twisting machine, belonging to the technical field of twisting machines. Background Technology

[0002] Textile machinery used for twisting yarn can be broadly categorized into three types: cotton spinning, tire cord spinning, and fiberglass spinning, collectively known as twisting machines. The spindle is a crucial component of the twisting machine; typically, each machine has about 100 spindles, mainly divided into two types: motor-driven and mechanical friction-driven. Mechanical friction spindles consist of a spindle rod and a spindle core. When a problem arises with the fit between the spindle rod and the core, the entire spindle needs to be replaced. Disassembling the spindle rod is relatively easy; simply disengage the clutch from the rod, and it can be pulled out by hand. Because the core is fixed, a relatively large torque is used to tighten it to prevent loosening due to spindle vibration during operation. Furthermore, the external accessories installed on the twisting machine leave very little space for core disassembly, making core removal very inconvenient.

[0003] Currently, the method for disassembling the spindle is to use a matching fork wrench and pipe wrench, requiring two people to work together, such as... Figure 2 As shown, one person needs to reach inside the twisting machine to engage the wrench 8 with the nut, while another person manually disassembles it bit by bit using the lever 6. After disassembling one spindle, the same process must be repeated when disassembling another. This two-person collaborative work is time-consuming, labor-intensive, and extremely inefficient, impacting equipment operating efficiency. Therefore, improving the existing disassembly and assembly device is an urgent need. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide an automatic disassembly and assembly device and method for the spindle of a glass fiber twisting machine, which solves the problems that have occurred in the prior art.

[0005] The automatic assembly and disassembly device for the spindle of a glass fiber twisting machine according to the present invention includes a main support plate. The main support plate is provided with a first transverse slide rail and a first lifting slide rail, wherein the first lifting slide rail is located on the left and right sides of the main support plate.

A second transverse slide rail and a second lifting slide rail are provided below the main support plate. The second transverse slide rail is slidably connected to the outside of the second lifting slide rail. A wrench is connected to the outside of the second transverse slide rail. The wrench is engaged with the lower end of the spindle.

[0040] The specific application of this embodiment is as follows: Figure 4 As shown, the first spindle is first disassembled, and the device is placed on the placement plate 3. The device is then fixed to the placement plate 3 using the left and right fixing bolts 15. The front end of the wrench 8 is used to hold the first spindle 4. The bushing 6 is connected to the upper end of the spindle 4 by the fixing bolts 15. The disassembly and lifting button is pressed.

When the upper sensor plate 10 senses the upper sensor, the motor is powered off, and the automatic disassembly is completed.

[0041] Next, disassemble the second spindle: After disassembling the first spindle, push the wrench 8 to the position of the second spindle, so that the left slot of the wrench 8 engages with the nut below the spindle. Push the bushing 19 above the spindle 4, press the disassembly lowering button, the motor reducer is powered on, and the bracket 11 drives the bushing to move downward along the lifting screw 13. When the lower sensor plate 21 senses the lower sensor 22, the motor is powered off. At this time, the bushing 19 is just engaged with the upper end of the spindle 4. Tighten the fixing bolts. Press the disassembly raise button to disassemble the second spindle.

[0042] Disassemble the third spindle again: After disassembling the second spindle, push wrench 8 to the third spindle, so that the right slot of wrench 8 engages the nut below the spindle.

[0048] S3: The motor drives the bushing 19 to move above the spindle 4. The bracket 11 drives the bushing 19 to move down along the lifting screw 13. When the lower sensor plate 21 senses the lower sensor 22, the motor is powered off. At this time, the bushing 19 just locks the upper end of the spindle 4, connecting the bushing 19 to the upper end of the spindle 4.

[0049] S4: Press the disassembly and lifting button. The bracket 11 drives the bushing 19 to move upward along the lifting screw 13. When the upper sensor plate 10 senses the upper sensor, the motor is powered off, completing the automatic disassembly of a set of spindles 4.
