When the flattening plate rotates, the elastic force can reset the flattening plate; when the smoothing plate does not rotate, the elastic piece can prevent the smoothing plate from rotating downwards due to gravity, so that the smoothing plate and the fixed plate are kept in an open state, the open state refers to the situation that the smoothing plate and the fixed plate are not attached together, and the smoothing plate and the fixed plate are opened at a certain angle.

The elastic member may be an elastic structure such as an elastic strip or a torsion spring, and the elastic strip may be a rubber strip, a rubber band, or the like.

When the elastic piece is the elastic strip, one end of the elastic strip is fixed on the fixing plate, the other end of the elastic strip is fixed on the smoothing plate, and the smoothing plate and the fixing plate are opened at a certain angle through the elasticity of the elastic strip to be in an opening state.

Fig. 1 and 2 show an overall structure and an exploded structure of a pacifier according to an embodiment of the present invention, respectively.

As shown in fig. 1 and 2, an embodiment of the present invention provides a pacifier, including: the plate-flattening device comprises a plate-flattening plate 1, a fixing plate 2, a torsion spring 3 and a connecting shaft 4, wherein at least one hinge ring 5 matched with the connecting shaft 4 is fixed on the plate-flattening plate 1 and the fixing plate 2 respectively, the fixing mode is preferably welded, or the hinge ring 5, the plate-flattening plate 1 and the fixing plate 2 are of an integrally formed structure, the connecting shaft 4 is inserted into the hinge ring 5, and the plate-flattening plate 1 and the fixing plate 2 are hinged.

As shown in fig. 3a and 3b, the fixing plate 2 is fixedly connected to the main body 8 of the encapsulation machine, thereby fixing the leveler to the main body 8 of the encapsulation machine. In one embodiment of the present invention, a through hole 7 is formed in the fixing plate 2, a screw hole is formed in the main body 8 of the encapsulation machine at a position corresponding to the through hole 201, and the screw 7 is screwed into the screw hole through the through hole 201, so that the fixing plate 2 is fixed on the main body 8 of the encapsulation machine.

Because the smoothing plate 1 is not fixed on the rubber coating machine main body 8 and can be rotated downwards by gravity, the torsion spring 3 is sleeved on the connecting shaft 4, one torsion arm of the torsion spring 3 is abutted against the fixing plate 2, the other torsion arm is abutted against the smoothing plate 1, the torsion spring 3 provides supporting force for the smoothing plate 1, the smoothing plate 1 is prevented from rotating downwards, and the smoothing plate 1 and the fixing plate 2 are in a horizontal state.

In one embodiment of the present invention, in order to maintain the hinge stability, the number of the hinge loops 5 on the leveling plate 1 is two, and the hinge loops are respectively the first hinge loop 501 and the second hinge loop 502 which are spaced apart, the number of the hinge loops 5 on the fixing plate 2 is also two, and the hinge loops are respectively the third hinge loop 503 and the fourth hinge loop 504 which are spaced apart, and the diameters of the first hinge loop 501, the second hinge loop 502, the third hinge loop 503 and the fourth hinge loop 504 are all the same.

When assembling the pacifier, the pacifier plate 1 and the fixed plate 2 are attached together, such that the first hinge loop 501 and the second hinge loop 502 intersect with the third hinge loop 503 and the fourth hinge loop 504, that is, the second hinge loop 502 is located between the third hinge loop 503 and the fourth hinge loop 504, the third hinge loop 503 is located between the first hinge loop 501 and the second hinge loop 502, the first torsion spring 301 is disposed between the first hinge loop 501 and the third hinge loop 503, the second torsion spring 302 is disposed between the second hinge loop 502 and the fourth hinge loop 504, and the connecting shaft 4 is inserted when the first hinge loop 501, the second hinge loop 502, the third hinge loop 503, the fourth hinge loop 504 and the two torsion springs 3 are aligned.

First torsion spring 301 and second torsion spring 302 can the syntropy setting, two torsion arms of first torsion spring 301 and two torsion arms of second torsion spring 302 respectively with the face butt of pacifying board 1 and fixed plate 2 homonymy, first torsion spring 301 and second torsion spring 302 provide the elasticity of a direction to pacifying board 1, when the installation pacifier, can only be according to elasticity for clockwise fixing the pacifier orientation on rubber coating machine main part 8, make the reverse and the gravity direction of pacifying board 1 of elasticity opposite, otherwise pacify board 1 can receive gravity downwardly rotating. It follows that this arrangement results in a mounting angle for the pacifier which is limited.

In order to solve the problem that the installation angle of the smoothing device is limited, the first torsion spring 301 and the second torsion spring 302 are arranged in a positive-negative mode, namely two torsion arms of the first torsion spring 301 are abutted to the surfaces of the same sides of the smoothing plate 1 and the fixing plate 2, two torsion arms of the second torsion spring 302 are abutted to the surfaces of the other sides of the smoothing plate 1 and the fixing plate 2, so that the first torsion spring 301 and the second torsion spring 302 provide two opposite force directions to the smoothing plate 1, when the smoothing device is installed on the glue wrapping machine main body 8 at any angle, the smoothing plate 1 cannot automatically rotate under the action of gravity, the wiring harness 9 can be touched with the smoothing plate 1 from two directions, and the tail of the adhesive tape 10 on the wiring harness 9 can be smoothed from any direction regardless of which the smoothing plate 1.

In order to prevent the connecting shaft 4 from escaping, the connecting shaft 4 is designed to be a connecting shaft having a boss 401 at an end thereof, the boss having a diameter larger than an inner diameter of the hinge ring 5, and after the connecting shaft 4 is inserted into the first hinge ring 501 from one side, the boss 401 plays a role of blocking, preventing the connecting shaft 4 from being completely inserted into the first hinge ring 501. Correspondingly, a locking pin 6 is inserted into the fourth hinge loop 504 from the outside, preventing the connecting shaft 4 from moving out of the other side.

Alternatively, the connecting shaft 4 may be designed to have a hollow structure, and a locking pin 6 may be inserted into each of the ports at both ends of the connecting shaft 4 to prevent the connecting shaft 4 from coming out.

The working principle of the smoothing device is as follows: after the rubber coating of the wire harness 9 is finished, the rubber coating machine main body 8 moves relative to the wire harness 9, the flatting device is pulled to move towards the direction of the wire harness 9, meanwhile, the angle of the rubber coating machine main body 8 is adjusted, the adhesive tape 10 is cut through the cutter 11 fixed on the rubber coating machine main body, after the cutting is finished, the flatting plate 1 and the tail part of the adhesive tape 10 left on the wire harness 9 are in contact, at the moment, the elastic potential energy generated by the torsion spring 3 is smaller than the kinetic energy between the flatting plate 1 and the wire harness 9, the torsion spring 3 is elastically deformed, and the tail part of the adhesive tape 10 is attached to the wire harness 9 through the kinetic energy between the flatting; when the wire harness 9 leaves the pacifying plate 1, the pacifying plate 1 loses kinetic energy with the wire harness 9, and elastic potential energy generated by the torsion spring 3 enables the pacifying plate 1 to reset and the fixing plate 2 to be in a horizontal state.
