In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1 to fig. 3, a rotating mandrel mechanism 100 for a reel of rubber according to an embodiment of the present application will be described.

The rubber plate rotating mandrel mechanism 100 includes: the device comprises a fixed shaft 10, an outer rotating sleeve 20, a torsion spring 30, a bearing 40, an outer cylinder 50 and a pressure regulating assembly 60.

The fixed axle 10 is equipped with friction platform 11, outer swivel sleeve 20 is equipped with friction cover 21, outer swivel sleeve 20 cover is located on the fixed axle 10 just friction cover 21 with the 11 contacts of friction platform, pressure regulating subassembly 60 is fixed in just be used for adjusting on the fixed axle 10 friction cover 21 with axial pressure between the friction platform 11, outer barrel 50 cover is located on the outer swivel sleeve 20, torsional spring 30 with bearing 40 is located outer swivel sleeve 20 with between the outer barrel 50, wherein, torsional spring 30's one end is fixed in on the fixed axle 10, the other end is fixed in on the outer barrel 50.

It can be understood that, in the rubber rotary mandrel mechanism 100 of the present application, since the friction sleeve 21 contacts with the friction table 11 and the pressure regulating assembly 60 can apply axial pressure between the friction sleeve 21 and the friction table 11, a friction force is inevitably generated between the friction sleeve 21 and the friction table 11, and thus a pre-tightening force is formed between the fixed shaft 10 and the outer rotary sleeve 20.

Obviously, the larger the pressure applied by the pressure regulating assembly 60 is, the larger the friction force between the friction sleeve 21 and the friction table 11 is, and the smaller the pressure applied by the pressure regulating assembly 60 is, the smaller the friction force between the friction sleeve 21 and the friction table 11 is, that is, the magnitude of the pre-tightening force of the fixed shaft 10 and the outer rotating sleeve 20 can be adjusted by adjusting the pressure applied by the pressure regulating assembly 60.

Therefore, in the actual application process, when the rubber plate rotating mandrel mechanism 100 is applied to a rubber plate pre-tightening device of a sealing and labeling machine, the rubber plate can be fixed on the outer cylinder 50, and the rubber plate drives the outer cylinder 50 to rotate synchronously when being subjected to an external force. Since the torsion spring 30 and the bearing 40 are connected between the outer cylinder 50 and the outer rotating sleeve 20, the torsion spring 30 is inevitably elastically deformed when the outer cylinder 50 rotates. At this time, if the torsion force generated by the torsion spring 30 is less than or equal to the pre-tightening force between the fixed shaft 10 and the outer rotating sleeve 20, the fixed shaft 10 and the outer rotating sleeve 20 will not move relative to each other, so that the adhesive tape between the adhesive head and the adhesive disk can be kept tight.

In the process of winding the adhesive tape, the adhesive tape is subjected to external force increase, the torsion spring 30 generates elastic deformation increase, when the torsion force generated by the torsion spring 30 is larger than the pretightening force between the fixed shaft 10 and the outer rotating sleeve 20, the fixed shaft 10 and the outer rotating sleeve 20 can move mutually, namely the outer rotating sleeve 20, the outer barrel 50 and the adhesive tape can coaxially rotate in the same direction, so that the adhesive tape can be continuously output by the adhesive tape. The existence of the torsion spring 30 enables the adhesive tape to be continuously tensioned, so that the adhesive tape can be wound on an object more tightly, and the viscosity and the sealing performance are improved.

After the glue is wound, when the glue head rapidly stops pulling the glue disc, the glue disc always continues to rotate for a short distance due to inertia, and the adhesive tape between the glue head and the glue disc is loosened. In this application, because torsional spring 30's existence can turn into kinetic energy with elastic potential energy for the rubber tyer counter-rotation is a small distance, realizes the automatic effect of retrieving with taut of sticky tape, avoids twining the condition emergence of gluing and breaking away from the direction, in order to improve and seal the quality in succession.

In addition, in the machining process, the machining requirement on the surface roughness between the friction table 11 and the friction sleeve 21 is high, namely the friction coefficient is difficult to control through polishing and grinding, so that the pressure can be adjusted through the pressure adjusting assembly 60, and the pre-tightening force can be adjusted. Moreover, the rubber discs are different in model and optimal pre-tightening force, pressure can be adjusted through the pressure adjusting assembly 60, and adaptability is improved.

Compared with the prior art, the rubber disc rotating mandrel mechanism 100 provided by the application has the advantages that the friction sleeve 21 is arranged to be in contact with the friction table 11, so that pre-tightening force is formed between the fixed shaft 10 and the outer rotating sleeve 20, and the braking efficiency of the rubber disc is improved; axial pressure can be applied between the friction sleeve 21 and the friction table 11 through the pressure regulating assembly 60, so that the difficulty of pre-tightening force regulation is reduced, and the adaptability is improved; the torsion spring 30 and the bearing 40 are connected between the outer cylinder 50 and the outer rotary sleeve 20, so that the automatic recovery and tensioning of the adhesive tape can be realized, the adhesive tape winding and separation from the guide can be avoided, and the adhesive tape winding quality during continuous sealing can be improved.
