Description
Technical Field
The utility model relates to the field of spinning equipment, in particular to a paper tube locking mechanism of a servo yarn releasing manual spring expanding roller.
Background
As is well known, with the popularization of carbon fiber materials, the demand of carbon fiber yarns is also increasing year by year, particularly in wet winding, high-speed winding is a key index for realizing high productivity, servo yarn unwinding is a new technology, and yarns are unwound on paper drums by using a servo closed-loop mechanism for constant high-tension yarn unwinding, so that the paper drum yarn unwinding mechanism in equipment is widely applied, relatively large-tension unwinding is used as an air-expanding shaft in industry, slipping phenomenon is easy to occur, and the paper drum yarn unwinding mechanism is not suitable for factories without high-pressure air sources.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model provides the servo yarn-releasing manual spring expanding roller locking paper tube mechanism which does not need an air source and can not slip when yarns are released under high tension.
The technical scheme adopted for solving the technical problems is as follows: a servo yarn releasing manual spring expanding roller locking paper tube mechanism is characterized in that a servo motor is fixedly connected with a bearing seat, a shaft of the servo motor is connected with a main shaft, the main shaft is installed in the bearing seat through a bearing, an elastic sleeve is sleeved on the main shaft, two end faces of the elastic sleeve are in contact with inclined conical surfaces of a front pressing plate and a rear pressing plate, a compression spring is sleeved at the front end of the main shaft and is limited by the front pressing plate, a fixing seat is installed on the bearing seat, a handle is inserted on the fixing seat and can rotate around the fixing seat, the front end of the handle is fixed with a cam pressing block, and the cam pressing block is located at the rear side of the front pressing plate.
Two ends of the elastic sleeve are provided with uniform unloading grooves.
The outer cylindrical surface of the elastic sleeve is provided with knurling lines.
The utility model has the advantages of more stable mechanical mechanism, simple structure, no air source, less parts, low maintenance cost, stability and reliability, and no slipping when the yarn is unreeled under high tension.
Drawings
The utility model will be further described with reference to the drawings and examples.
FIG. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is a cross-sectional view of the present utility model.
In the figure, a bearing seat 1, a bearing 2, a servo motor 3, a gland 4, a main shaft 5, a front pressure plate 6, a rear pressure plate 7, an elastic sleeve 8, a compression spring 9, a cam pressing block 10, a handle 11, a fixed seat 12 and a bolt 13.
Detailed Description
In the figure, a servo motor 3 is fixedly connected with a bearing seat 1 through a bolt, a shaft of the servo motor 3 is inserted into a main shaft 5, power of the servo motor 3 is transmitted to an unreeling mechanism through a key slot, the main shaft 5 is arranged in the bearing seat 1 through two pairs of bearings 2, a gland 4 is arranged at the end part of each bearing 2, an elastic sleeve 8 is sleeved on the main shaft 5, uniform unloading grooves are formed in two ends of the elastic sleeve 8, deformation is facilitated, and knurled lines for increasing friction are formed in the outer cylindrical surface of the elastic sleeve 8. The two end faces of the elastic sleeve 8 are in contact with the inclined conical surfaces of the front pressing plate 6 and the rear pressing plate 7, the compression spring 9 is sleeved at the front end of the main shaft 5 and limited by the front pressing plate 6, and the front pressing plate 6 stretches the elastic sleeve 8 through the front inclined conical surface and the rear inclined conical surface of the front pressing plate 6 and the rear pressing plate 7 under the elasticity of the compression spring 9 to be used for tensioning the paper tube. The bearing seat 1 is provided with the fixing seat 12, the handle 11 can rotate around the fixing seat 12, the front end of the handle 11 is fixed with the cam pressing block 10, the cam pressing block 10 is positioned at the rear side of the front pressing plate 6, and the rear pressing plate 7 is fixed at the rear end of the main shaft 5 through the bolt 13.
When the carbon fiber paper tube needs to be assembled and disassembled: the handle 11 is lifted to drive the cam pressing block 10 to rotate, and the cam pressing block 10 is of an eccentric structure, so that the pressing plate 6 moves to the motor side before extrusion, and the elastic sleeve 8 retracts to the paper tube by virtue of the elastic force under the condition of no conical surface extrusion, so that the paper tube is conveniently taken down.
When the paper tube works on the yarn releasing mechanism, the paper tube needs to be fixed: the handle 11 is loosened, the handle 11 naturally sags, a certain gap is reserved between the cam pressing block 10 and the front pressing plate 6, the front pressing plate 6 moves towards the direction away from the servo motor 3 under the action of huge ejection force of the compression spring 9, two end faces of the elastic sleeve 8 are contacted with inclined conical surfaces of the front pressing plate 6 and the rear pressing plate 7, the front pressing plate 6 stretches the elastic sleeve 8 through the front inclined conical surface and the rear inclined conical surface under the elasticity of the compression spring 9 and is used for tensioning a paper cylinder, and the front pressing plate 6 slides on the main shaft 5 through a key groove to realize torque transmission.
