Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Specific implementations of the present invention are described in detail below with reference to specific embodiments.

As shown in fig. 1 to 2, a structure of a single cylinder bobbin creel lifting device according to an embodiment of the present invention includes:

the bobbin bracket component 1 is used for clamping and fixing the bobbin yarn 2;

the bobbin holder seat rotating assembly 3 is characterized in that the bobbin holder assembly 1 and the bobbin holder seat rotating assembly 3 are fastened into a rotatable bar swing part;

the winding roller assembly 9 is used for driving the cone yarn 2 contacted with the winding roller assembly to wind the yarn 11; and

the three-stroke air cylinder assembly 8 is characterized in that the movable end of the three-stroke air cylinder assembly 8 is connected to the bobbin holder seat rotating assembly 3 through a joint bearing, the fixed end of the three-stroke air cylinder assembly 8 is installed on the fixed support 7, and the three-stroke air cylinder assembly 8 compresses or lifts to push the bobbin holder seat rotating assembly 3 to swing so as to realize pressurization, half separation and full separation of the bobbin yarn 2 relative to the winding roller assembly 9.

In practical application of the embodiment, the creel assembly 1 is a clamping component of the cone yarn 2, so that the cone yarn 2 is kept at a position and can flexibly rotate, and the fixed support 7 is an installation support at the fixed end of the three-stroke cylinder assembly 8; the bobbin carriage base rotating assembly 3 is a mounting base of the bobbin carriage assembly 1 and is also a lever swing for transmitting the movement of the three-stroke cylinder assembly 8. The invention can ensure that the tension of the yarn 11 is stable during working in the processing process, and the cone yarn 2 is completely separated from the friction roller to avoid the damage of the yarn 11 when the yarn 11 breaks or stops working.

As shown in fig. 1, as a preferred embodiment of the present invention, a yarn guide 10 for holding a yarn 11 and uniformly distributing the yarn is provided on the winding roller assembly 9.

As shown in fig. 1 to 2, as another preferred embodiment of the present invention, the three-stroke cylinder assembly 8 includes:

the locking assembly comprises a locking sleeve 14 and a locking steel ball 15;

a first pressurizing cylinder 12, which is matched with the piston rod 17 and is used for pressurizing the cone yarn 2;

the second lifting cylinder 13 is matched with the locking assembly and used for lifting the cone yarn 2; and

a third positioning cylinder 16 for positioning and limiting the movement of the second lifting cylinder 13;

when the second lifting cylinder 13 is lifted, the locking assembly locks the piston rod 17 to realize lifting; when the second lift cylinder 13 is not pressurized, the locking assembly releases the piston rod 17.

The working principle of the three-stroke cylinder assembly 8 is as follows: the basic parameters, namely, the compressed air pressure P1 < P2, the sectional area of the first pressurizing cylinder 12 < the sectional area of the second lifting cylinder 13 < the sectional area of the third positioning cylinder 16, so that the thrust F1 generated by the first pressurizing cylinder 12 < the thrust F2 generated by the second lifting cylinder 13 < the thrust F3 generated by the third positioning cylinder 16.

The first pressurizing cylinder 12 is a force applying component for pressurizing the cheese 2, has a vibration absorbing function and is a basic executing component of the mechanism; the second lifting cylinder 13 is a functional part for lifting the cone yarn 2 in a short distance against the acting force of the first pressurizing cylinder 12; the locking sleeve 14 is tightly held by the piston rod 17 by the conical locking steel ball 15 under the combined action of the upward moving acting force of the second lifting cylinder 13 and the downward acting force of the spring, and the piston rod 17 is lifted upwards under the pushing of the second lifting cylinder 13. When the pressure of the second lifting cylinder 13 is relieved, the cylinder and the locking sleeve 14 move downwards under the action of the spring force, the locking steel ball 15 is released, the piston rod 17 is not locked any more, and the working state of the first pressurizing cylinder 12 is recovered; the third positioning cylinder 16 mainly plays a positioning role, and is a control for limiting two strokes of the second lifting cylinder 13, and is an auxiliary execution component of the mechanism.

In practical application, in a pressurized state (normal operating state): the first pressurizing cylinder 12 pressurizes, the second lifting cylinder 13 and the third positioning cylinder 16 release pressure, the first pressurizing cylinder 12 is in a single-cylinder working state, and constant pressure is applied to the cone yarn 2 to enable the cone yarn 2 to be in close contact with the winding roller assembly 9 so as to drive the cone yarn 2 to be wound according to a constant linear speed; the cylinder stroke distance varies as the diameter of the package 2 varies, the maximum stroke distance H1 being related to the maximum diameter of the package 2. In a half-disengaged state (normal operating tension adjustment state): a first pressurizing cylinder 12, a second lifting cylinder 13 and a third positioning cylinder 16 are used for pressurizing, and all the three cylinders are in a pressurizing state; the second lifting cylinder 13 pushes the locking sleeve 14 to move upwards under the pressurization, the locking steel ball 15 tightly locks the piston rod 17 under the combined action of the spring and the locking sleeve 14, the piston rod 17 is driven to move upwards due to the fact that the thrust F2 generated by the second lifting cylinder 13 is larger than the thrust F1 generated by the first pressurizing cylinder 12, the thrust F2 generated by the second lifting cylinder 13 is smaller than the thrust F3 generated by the third positioning cylinder 16, the third positioning cylinder 16 moves to the limit position to play a limiting role, the maximum lifting distance of the second lifting cylinder 13 is H2, the lifting distance can just enable the bobbin yarn 2 to be separated from the winding roller assembly 9, the yarn guide 10 can still hold the yarn 11, and the bobbin yarn 2 can keep normal winding of the yarn 11 by means of the inertia speed. In the fully disengaged state (spinning end breakage or shutdown state): the first pressurization cylinder 12 pressurizes or releases pressure (the equipment is electrified to pressurize, the equipment is cut off the power supply to release pressure), the second lifting cylinder 13 pressurizes or maintains pressure (the equipment works to pressurize, the equipment is cut off the power supply to maintain pressure), and the third positioning cylinder 16 releases pressure: the second lifting cylinder 13 pushes the locking sleeve 14 to move upwards under the pressurization effect, the locking steel ball 15 tightly locks the piston rod 17 under the combined action of the spring and the locking sleeve 14, the piston rod 17 is driven to move upwards due to the fact that the pushing force F2 generated by the second lifting cylinder 13 is larger than the pushing force F1 generated by the first pressurizing cylinder 12, the third positioning cylinder 16 is in a pressure relief state, the second lifting cylinder 13 pushes the third positioning cylinder 16 to move upwards to a limit position, the maximum lifting distance of the second lifting cylinder 13 is H2+ H3, the lifting distance enables the bobbin yarn 2 to be completely separated from the winding roller assembly 9, and under the condition that the equipment is powered off, the locking sleeve 14 and the locking steel ball 15 can still tightly lock the piston rod 17 to keep the position state of the bobbin yarn 2 due to the fact that the second lifting cylinder 13 is in a pressure maintaining state.

In one aspect of the present embodiment, as shown in fig. 3, the third positioning cylinder 16 may be replaced by a positioning pin, and the positioning pin may be a cylinder or a solenoid valve to control the extension and retraction of the positioning pin, so as to implement the control of two strokes of H2 and H3, which is not specifically limited herein.

As shown in fig. 1, as another preferred embodiment of the present invention, a sector arc curved surface concentric with the rotation center of the bobbin creel base rotating assembly 3 is provided, and a friction damping assembly acting on the sector arc curved surface is provided on the fixed support 7, and the friction damping assembly is used for absorbing high-frequency vibration generated by the bobbin yarn 2 in high-speed rotation and impact during pressurization and lifting.

In practical application, the friction damping assembly acts on the sector arc curved surface to form a friction pair to absorb high-frequency vibration generated in high-speed winding.

As shown in fig. 1, as another preferred embodiment of the present invention, the friction damping module includes:

the friction resistance piece 4 is made of a non-metal self-lubricating material, is slidably mounted on the fan-shaped arc curved surface and is used for increasing the friction resistance;

a pressing plate spring 5 for pressing the frictional resistance member 4; and

and the pressure regulating screw 6 is used for regulating the deformation amount of the pressure plate spring 5 so as to change the friction force.

In practical application, the frictional resistance member 4 is made of a self-lubricating wear-resistant material, so that the interface friction coefficient is stable; a force application member generating a frictional force by rubbing the pressure plate spring 5; the pressure regulating screw 6 can change the friction force of the friction pair by regulating the deformation of the pressure plate spring 5, thereby achieving the best effect of vibration absorption.

The embodiment of the invention provides a single-cylinder bobbin creel lifting device, which can ensure that the tension of yarn 11 is stable during working, the bobbin yarn 2 is completely separated from a friction roller to avoid the damage of the yarn 11 when the yarn 11 breaks or stops working, the pressurizing state, the semi-separating state and the full-separating state of the device are realized through a three-stroke cylinder assembly 8, the linkage with other mechanisms is not needed, the working procedures of upper machine combined adjustment are reduced, the daily maintenance is convenient, the pneumatic element is completely utilized to complete the action, the whole device is energy-saving and environment-friendly, and the device is suitable for the environment of a spinning workshop with high humidity, high temperature and high dust.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
