[0001] This utility model relates to an auxiliary device for disassembling and assembling the clamping plate of a spinning sliver winding machine, belonging to the technical field of auxiliary devices for winding machines. Background Technology

[0002] The spinning sliver winding machine is a key piece of equipment in the combing preparation process of the combing spinning system in the textile industry. Its core function is to combine and draft multiple cotton slivers (or other fiber slivers) and then wind them into uniform small rolls for use by the combing machine.

[0003] During production, the equipment requires regular manual maintenance, including: disassembling and assembling the chuck and replacing the bearings, and then adjusting the level of the chuck to ensure that the bobbin is not damaged when the chuck rotates, thereby producing qualified slivers.

[0004] However, the maintenance process has drawbacks:

[0005] Disassembly issues: Currently, the clamp is disassembled by prying. Repeated operation can easily damage and deform the clamp, increase the levelness error during installation, affect the coaxiality of the clamp and the tube, and thus damage the tube.

[0006] Installation issues: Manually hammering the installation chuck can easily lead to uneven force and installation tilt, which can also cause damage to the cylinder. Utility Model Content

[0008] This utility model discloses an auxiliary device for disassembling and assembling the clamping plate of a spinning sliver winding machine, including a transfer plate and a buffer rod assembly used in conjunction with the transfer plate.

[0016] A buffer pad is also provided on the end face of the impact block, which can abut against the side of the adapter plate.

[0017] Several anti-slip grooves are provided on the outer wall of the main body of the sleeve.

[0018] One end of the impact rod and the buffer spring are placed inside the sliding cavity, and the damping fluid is filled into the sliding cavity.

[0044] like Figures 1-9 As shown, this embodiment is achieved through the following technical solution:

[0045] The adapter plate 1 is used in conjunction with the buffer rod assembly.

[0046] The buffer rod assembly includes: an impact sleeve rod 2 that can abut against one side of the adapter plate 1, an impact rod 4 that is movably inserted inside the impact sleeve rod 2, a protective sleeve seat 3 that is fitted on the impact sleeve rod 2, and the impact rod 4 that can pass through the protective sleeve seat 3.

[0047] The impact sleeve 2 is equipped with a buffer spring 5, and one end of the impact rod 4 abuts against the buffer spring 5.

[0048] The impact sleeve 2 is also filled with damping fluid, and the impact rod 4 and the buffer spring 5 can move in the damping fluid.

[0049] Specifically, a positioning hole 102 is provided on the center of the side of the adapter plate 1, and a plurality of adapter holes 101 are also provided on the adapter plate 1. The adapter holes 101 can correspond to the mounting holes on the clamping plate 6. In this embodiment, the positions of the adapter holes 101 and the mounting holes on the clamping plate 6 are corresponding, and screws can be connected to the adapter holes 101 and the mounting holes on the clamping plate 6, thereby realizing the connection and fixation between the adapter plate 1 and the clamping plate 6. In this embodiment, the clamping plate 6 and the adapter plate 1 are coaxially combined, thereby ensuring that the adapter plate 1 can evenly transmit the impact force to the clamping plate 6.

[0050] Specifically, the impact sleeve 2 includes: a sleeve body 201, and a sliding cavity 203 is provided inside the sleeve body 201.

[0051] A positioning flange 202 is provided on the outer side of the sleeve body 201 near the opening of the sliding cavity 203.

[0052] An impact stop 204 is provided at one end of the sleeve body 201 away from the positioning flange 202, and a positioning protrusion 205 that cooperates with the positioning hole 102 is provided on the end face of the impact stop 204.

[0053] A buffer pad 207 is also provided on the end face of the impact block 204, and the buffer pad 207 can abut against the side of the adapter plate 1.

[0054] The outer wall of the sleeve body 201 is provided with several anti-slip grooves 208.

[0055] One end of the impact rod 4 and the buffer spring 5 are disposed inside the sliding cavity 203, and the damping fluid is filled inside the sliding cavity 203; the impact rod 4 and the buffer spring 5 can move within the damping fluid.

[0056] The sliding cavity 203 is filled with damping fluid. When the piston 401 moves within the cavity, it is divided into a compression stroke and a reset stroke.

[0057] Compression stroke: The piston section 401 compresses the damping fluid in front and squeezes the buffer spring 5. Under pressure, the damping fluid flows through the damping groove 404 to the space behind the piston section 401. This flow process generates a significant damping force, converting the impact kinetic energy into heat energy and dissipating it, thereby effectively mitigating the impact.

[0058] Reset stroke: When the external force decreases or disappears, the compressed buffer spring 5 releases energy, pushing the piston part 401 to move in the opposite direction toward the sheath seat 3. At this time, the damping fluid flows back to the space in front of the piston part 401 through the damping groove 404, which also generates damping force, making the reset process smooth and controllable and avoiding violent rebound of the component.

[0059] Specifically, the sheath seat 3 is fitted and connected to the positioning flange 202.

[0060] The sheath seat 3 is provided with a protruding ring 301, which can be inserted into the sliding cavity 203. The outer wall of the protruding ring 301 is provided with several sealing grooves 302. A sealing ring is provided in the sealing groove 302 to achieve the sealing between the sheath seat 3 and the impact sleeve rod 2.

[0061] Specifically, the impact rod 4 includes a rod body 402, and a buffer block 403 is sleeved on one end of the rod body 402. In this embodiment, the buffer block 403 is made of rubber.

[0062] One end of the rod 402 is provided with a piston part 401, and a plurality of damping grooves 404 are provided on the outer wall of the piston part 401, and the damping fluid can flow from the damping grooves 404.

[0063] A positioning retaining ring 405 is provided on the outer wall of the rod body 402. The end face of the convex ring 301 abuts against the side of the positioning retaining ring 405 to limit the impact rod 4 on the impact sleeve rod 2.

[0064] The piston part 401 can be disposed in the sliding cavity 203.

[0065] Specifically, both the positioning hole 102 and the positioning protrusion 205 are tapered.

[0066] Specifically, a magnet 206 is embedded in the positioning protrusion 205. Both the positioning hole (102) and the positioning protrusion (205) are conical. Combined with the attractive force of the magnet (206), this ensures that the positioning protrusion (205) can be quickly and accurately inserted into the positioning hole (102), such as... Figure 7 As shown. In use, the axial impact force of the impact sleeve 2 can be transmitted to the adapter plate 1 through the impact stop 204, and the positioning protrusion (205) is only used for positioning. The buffer pad (207) can abut against the side of the adapter plate (1) to provide initial cushioning.

[0067] The specific working principle of this utility model is as follows:

[0068] When disassembling and assembling the clamping plate 6, the adapter plate 1 is fixedly connected to the clamping plate 6. The impact sleeve 2 is manually operated so that the positioning protrusion 205 is inserted into the positioning hole 102. Furthermore, the buffer block 403 on the impact rod 4 is manually hammered with an external tool. The piston part 401 moves in the sliding cavity 203. The damping fluid and the buffer spring 5 can offset part of the impact force received by the impact rod 4, thereby buffering the rigid impact of the impact sleeve 2 on the adapter plate 1. The adapter plate 1 evenly transmits the impact force to the clamping plate 6, thereby realizing the flexible disassembly and assembly of the clamping plate 6 on the frame 7, and also preventing the clamping plate 6 from tilting due to uneven force.

[0069] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
