Description
Technical Field
The invention relates to the technical field of plastic film production machinery, in particular to a novel rotating device of a film blowing machine.
Background
The film blowing machine generally comprises the processes of extruding and blowing the film, forming a film tube from the film, heating and extending the film tube, rolling the film and the like. The film blowing device is mainly used for blowing the film by a film blowing port of the rotary film blowing device, and the rotary power drives the speed reducer through the motor to continuously rotate for 360 degrees. The existing rotary film blowing device is large in size, complex in structure and has the defect that the film blowing is not smooth and uniform enough due to the fact that the rotation is not stable enough.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a novel film blowing machine rotating device which is simple and reasonable in structure and stable in rotation.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a novel film blowing machine rotating device comprises a motor, a speed reducer connected with the motor, a pinion, a gear turntable, a copper sleeve and a carbon brush, wherein the rotating device comprises a base, the base is provided with a circular feed inlet, a support frame is fixedly arranged above the base, a hollow cylindrical rotating cylinder is arranged in the middle of the support frame, a sealing ring is arranged above the rotating cylinder, the gear turntable is arranged above the sealing ring, the pinion meshed with an edge gear of the gear turntable is arranged on one side of the gear turntable, the pinion is connected with the speed reducer, the speed reducer is arranged at one end of the support frame, and the speed reducer is connected with the motor; a support seat is fixedly arranged at the other end of the support frame, and 3 carbon brushes are fixedly connected with the support seat; the gear carousel lower surface fixed connection be connected with a plurality of connecting strips, connecting strip and copper sheathing fixed connection, the copper sheathing be provided with 3, the carbon brush with the contact of copper sheathing one-to-one.
The copper bush is connected with the heating wire, one side of the copper bush is provided with the carbon brush, the carbon brush is connected with the power line, and the power line is connected with the heating wire through the carbon brush and the copper bush, so that the uniform heating is ensured, and the film blowing quality is improved; meanwhile, the power supply can supply power to the continuously rotating winding motor through the carbon brush. According to the invention, 3 copper sleeves are arranged to connect different heating wires, so that the winding of the wires is avoided, the running stability of the rotating device is improved, and the blown film is smooth and uniform.
Furthermore, an inner pipe is arranged in the middle of the rotating device and connected with the circular feed inlet of the base. The inner pipe is vertically arranged.
Furthermore, an outer pipe is arranged on the outer side of the inner pipe, and the outer pipe is arranged above the base.
Preferably, the outer surface of the outer pipe is provided with a bearing. The bearing is arranged to bear thrust load during high speed operation.
More preferably, the outer surface of the outer pipe is provided with a thrust bearing, a second bearing, a first copper sleeve, a third bearing and a second copper sleeve from bottom to top. This is so set up because: 1. the bearing capacity of only one thrust bearing is limited, the precision requirement is strict, and otherwise, the upper part of the extrusion die head is slightly inclined; 2. because the thrust bearing is close to the vertical central pipeline-outer pipe, the pressure on a single copper sleeve is huge, the abrasion is serious, and the good sealing performance is not easy to continuously maintain. The bearings and the copper bush can delay the abrasion degree of the copper bush, so that the rotation is more stable, the requirement on the precision of the thrust bearing is greatly reduced, and the flatness and the uniformity of a produced film can be better ensured.
Furthermore, the carbon brush is connected with an electromagnetic relay, the carbon brush is connected with a normally open contact of the electromagnetic relay, and the normally closed contact of the electromagnetic relay is connected with the audible and visual alarm in series. When the copper sleeve contacted with the carbon brush rotates, current flows through the electromagnetic relay, and the normally open contact closes the circuit and is conducted; when the copper sleeve stops operating, the electromagnetic relay is powered off, the normally closed contact is closed, the acousto-optic alarm circuit is switched on, and the acousto-optic alarm reminds the rotating device to stop operating.
The invention has the beneficial effects that:
the invention has reasonable structure, can delay the abrasion degree of the copper sleeve through the arrangement of the plurality of bearings and the copper sleeve, ensures more stable rotation, greatly reduces the requirement on the precision of the thrust bearing, can better ensure the flatness and the uniformity of a produced film, and has better quality of the produced film.
