A pair of first cavities 35 which are symmetrically distributed are formed in the shaft of the winding shaft 13 close to the end part, and a T-shaped rod 34 is fixedly connected to the inner wall of each first cavity 35 through a spring; the top end of the T-shaped rod 34 penetrates through the first cavity 35 and extends out of the winding shaft 13; a third groove 36 is formed in the inner walls of the upper module 16 and the lower module 17 at the position corresponding to the T-shaped rod 34; a first air bag 38 is arranged between the bottom end of the T-shaped rod 34 and the inner wall of the first cavity 35; the winding shaft 13 is provided with a group of second cavities 39; the second cavity 39 is hermetically and slidably connected with a push plate 391; a group of third sliding grooves 37 are formed in the outer side wall of the winding shaft 13; the fixed column 14 is an L-shaped column, and the fixed column 14 is slidably connected in the third sliding chute 37 and is fixedly connected to the inner wall of the third sliding chute 37 through a spring; one end of the fixed column 14 penetrates through the second cavity 39 and is fixedly connected to the side wall of the push plate 391 far away from the first cavity 35, and the other end of the fixed column 14 extends out of the winding shaft 13; the first and second air bags 38 and 39 are communicated with each other; when the winding machine works, after the positioning groove 18 and the fixed column 14 are installed, a certain gap is formed between the positioning groove 18 and the fixed column 14, when the winding shaft 13 rotates for winding, the winding die 15 shakes back and forth due to the gap between the positioning groove 18 and the fixed column 14, and the winding effect is affected, so when the upper module 16 and the lower module 17 are installed, the bottom of the third groove 36 firstly presses the T-shaped rod 34 downwards, the T-shaped rod 34 presses downwards to extrude the first air bag 38, air in the first air bag 38 enters the second cavity 39, the fixed column 14 is driven to move by pushing the push plate 391 to move, the side wall of the fixed column 14 and the side wall of the positioning groove 18 are contacted with each other, the winding die 15 is further pushed to move, the opposite side walls of the fixed column 14 and the T-shaped rod 34 are respectively attached to the side walls of the positioning groove 18 and the third groove 36, the winding die 15 is further transversely fixed on the winding shaft 13, and the situation that the winding die 15 swings back and forth on the winding shaft 13 is prevented, further improving the winding effect.

A second air bag 43 is arranged between the side wall of the fixed column 14 far away from the push plate 391 and the third sliding chute 37; the fixed column 14 extends out of the third sliding chute 37 and is provided with a corrugated groove 4 on the side wall far away from the push plate 391; an air outlet cavity 41 is formed in the corrugated groove 4; a group of air outlet holes 42 are formed at the bottom of the corrugated groove 4; the air outlet hole 42 and the air outlet cavity 41 are communicated with each other; the second air bag 43 and the air outlet cavity 41 are communicated with each other; the during operation, can extrude second gasbag 43 when fixed column 14 removes in third spout 37, the gas of second gasbag 43 can be cleared up constant head tank 18 inner wall through venthole 42, and the ripple groove 4 that sets up, when fixed column 14 and constant head tank 18 lateral wall are hugged closely, the boss of ripple groove 4 can contact each other with constant head tank 18 lateral wall, then impurity can get into in 4 recesses of ripple groove under the condition that can't drop, can not influence hugging closely of 4 bosses of ripple groove and constant head tank 18 lateral wall, and then can not influence the fixed effect of winding former 15.

A fourth groove 44 is formed at the top end of the fixed column 14, and a top rod 45 is fixedly connected to the bottom of the fourth groove 44 through a spring; during operation, when last module 16 and lower module 17 are fixed each other, ejector pin 45 can be extruded to constant head tank 18 tank bottom this moment, and when removing the fixed effect between last module 16 and lower module 17, ejector pin 45 can be earlier with last module 16 and the preliminary separation between lower module 17 under the elasticity of spring, prevents that the condition of screens groove 23 is blocked into once more to the tip of falling T-shaped pole 34.

Example two:

as shown in fig. 6, in a first comparative example, as another embodiment of the present invention, a sponge block 46 is fixed to the sidewall of the oil outlet opening; the side wall of the sponge block 46 close to the oil outlet cavity 33 is provided with tentacles 47, and the tentacles 47 extend into the oil outlet cavity 33; the during operation, in order to prevent spraying of lubricating oil extravagant, so be equipped with sponge piece 46 at the opening part of oil outlet, lubricating oil has can slowly ooze, and is equipped with tentacle 47 at sponge piece 46 lateral wall, and tentacle 47 can stretch into out in the oil pocket 33, can suction lubricating oil continuously for the seepage rate of lubricating oil guarantees lubricated effect.

The working principle is as follows: when the upper module 16 and the lower module 17 are in operation, the upper fixing column 14 and the positioning groove 18 on the winding shaft 13 are used for limiting, at this time, the inclined plane of the inverted-L-shaped plate 21 is contacted with the inclined plane of the opening of the first groove 22, because the inclined planes of the inverted-L-shaped plate and the first groove 22 are parallel to each other, in the folding process of the upper module 16 and the lower module 17, the inclined plane of the first groove 22 can push the inverted-L-shaped plate 21 to move to extrude the spring, when the inclined planes of the inverted-L-shaped plate and the second groove are separated from each other, the end part of the inverted-L-shaped plate 21 can be pushed to move towards the clamping groove 23 under the action of the spring elasticity, so as to clamp the upper module 16 and the lower module 17, at the same time, the bottom of the third groove 36 can press the T-shaped rod 34 downwards, the T-shaped rod 34 can press the first air bag 38, the air bag 38 can enter the second cavity 39, the fixing column 14 is driven to move by pushing plate 391, so that the side wall of the fixing column 14 is contacted with the side wall of the positioning groove 18, further pushing the winding former 15 to move to make the opposite side walls of the fixing column 14 and the T-shaped rod 34 respectively cling to the side walls of the positioning groove 18 and the third groove 36, so as to transversely fix the winding former 15 on the winding shaft 13; when the inverted-L-shaped plate 21 enters the first groove 22, the top end of the inverted-L-shaped plate 21 is pushed by the inclined surface of the first groove 22 to contact with the magnetic ball 29, then the magnetic ball 29 is pushed upwards, when the inverted-L-shaped plate 21 is clamped into the clamping groove 23, the top end of the inverted-L-shaped plate 21 is separated from the magnetic ball 29, the magnetic ball 29 moves downwards under the action of the spring and is clamped between the inverted-L-shaped plate 21 and the side wall of the first groove 22 to play a clamping role, and the upper module 16 and the lower module 17 are prevented from being separated due to the fact that some foreign people push the U-shaped rod 24 manually under the unattended condition; when the upper module 16 and the lower module 17 are clamped and fixed, the side wall of the inverted L-shaped plate 21 is pushed by the opening inclined surface of the first groove 22 to extrude the oil bag 32, lubricating oil of the oil bag 32 enters the oil outlet cavity 33 and is sprayed through the oil outlet hole, the inclined surface of the first groove 22 and the inclined surface of the inverted L-shaped plate 21 are lubricated, friction force is reduced, installation is smoother, and installation time is further saved; when the fixing effect of the upper module 16 and the lower module 17 needs to be released, the U-shaped rod 24 is pulled by hand, then the electromagnet 28 is electrified to adsorb the magnetic ball 29, and then the clamping groove 23 is pushed by the end part of the inverted L-shaped plate 21 when the U-shaped rod 24 is pushed by hand through the end part of the L-shaped plate 27.
