Description

Multi-cutter longitudinal cutting film trimming traction device

Technical Field

The utility model relates to a tire rubber film production facility field says in detail to a multitool indulges cuts out film deburring draw gear.

Background

As is known, multi-blade longitudinal cutting machine equipment is a main equipment in the tire industry, wherein the function of a film trimming and winding device is very important, but a great potential safety hazard exists. The thin film is cut into films with required width after being guided out at a guide station, a cloth liner coiling station, a cloth rubbing and crease removing station and being cut by a cutting knife in a multi-knife longitudinal cutting machine. The films generated on the two sides after cutting are automatically collected into a pile and then are processed in a centralized way under the traction of a film winding driving wheel. In the normal production process, after the films are trimmed, the films are drawn into a pile through a traction wheel, and when the films are broken, an operator needs to put the films on the traction wheel again; or when the number of the films under the traction wheel is large and the container below the traction wheel cannot contain the films, an operator needs to cut off and clean the films. In two above-mentioned operation processes, operating personnel hand and traction wheel contact or distance are too near, and speed reducer output torque transmits the driven sprocket of traction wheel through sprocket, chain moment of torsion, drives the traction wheel rotation again, pulls the film on the traction wheel, need not great moment of torsion and drives the traction wheel, so there is operating personnel and is drawn into the danger of traction wheel along with the film, and personal safety exists hidden danger.

Disclosure of Invention

In order to overcome the not enough of prior art, the utility model provides a multitool indulges cuts out film deburring draw gear adjusts to the required moment of torsion size of production, protects operating personnel's personal safety, and applicable in the operating mode at the similar position of other trades to protection operating personnel's safety improves factor of safety.

The utility model provides a technical scheme that its technical problem adopted is: a multi-knife longitudinal cutting film trimming traction device is characterized in that an inner bushing of a film traction driven sprocket device is arranged on a film traction wheel shaft, the inner bushing is sleeved with a sprocket inner sleeve, a sprocket gap is sleeved on the sprocket inner sleeve, two brake pads are arranged on the left side and the right side of the sprocket in a matched mode, a brake top plate is sleeved on the inner bushing and is in contact with the brake pads on the inner side, a spring disc outer sleeve is further sleeved on the inner bushing on the inner side of the brake top plate, six counter bores on the same circumference are uniformly distributed on the outer side surface of the spring disc outer sleeve, and each counter bore is provided with a compression spring, the outer end of the compression spring is pressed on the inner side surface of the brake top plate, the inner end of the inner bushing is provided with a locking nut in a threaded fit mode, and the chain wheel is connected with a speed reducer driving chain wheel of a motor speed reducer through a chain.

The beneficial effects of the utility model are that, can confirm required moment of torsion size according to film traction force size, through adjustment driven sprocket brake equipment to change drive traction wheel moment of torsion size, make traction force size corresponding with the moment of torsion size. The torque with proper size can be adjusted according to the field traction wheel, and when an operator rolls the sleeves into the traction wheel, the traction wheel can generate sliding friction with the driven chain wheel to stop rotating, so that the personal safety of the operator is protected. Avoid too big because of speed reducer output torque, the traction wheel is transmitted to on the same side, and the moment of torsion is too big, and operating personnel is drawn into the traction wheel, produces the potential safety hazard.
