Abstract
The utility model relates to a roll delivering tension controlling device for a one-armed rolling slitter machine. The roll delivering tension controlling device for the one-armed rolling slitter machine comprises a tension device and a tension controller of the tension device, wherein the tension device is fixed at one end of a rotating shaft of a rolling film roll and used for transmitting torsion to the rotating shaft of the rolling film roll. The tension device comprises a coupling and a clutch which are in series connection. An input end of the coupling is connected with the rotating shaft of the rolling film roll. The clutch is a magnetic powder clutch, and an output end of the clutch is fixed on a support frame of equipment. The tension controller transmits a magnetizing current to the clutch. The magnetic powder clutch is used as the tension device. The roll delivering tension controlling device for the one-armed rolling slitter machine is high in responding speed, simple in structure, free of pollution, noise and impact and shock, convenient to maintain, and the like.
Description
Technical field
The utility model relates to a kind of single armed rolling cutting machine hai roll tenslator.
Background technology
At present, be used for BOPP, RPP film dividing institute single armed rolling cutting machine with rolling, its hai roll tenslator is the air pressure control air operated friction clutch of setting by the output of Pneumatic control proportioning valve, controls the tension force of hai roll.Its structure unreels film volume 1 and rotates under the driving of rolling film volume motor as shown in Figure 1, and the rotating shaft 12 that is fixed on the film volume core 11 drives driving and driven gear 2,3 rotations, and the friction lining 41 that driven gear 3 drives air operated friction clutch 4 rotates together.Because the variation of unwinding tension, can signal be passed to tension control assembly 5 by the tension pick-up that is installed in the equipment, tension control assembly 5 is regulated air-flow ratio adjusting valve 44 automatically according to the variation of tension force, control the flow of air-flow ratio adjusting valve 43 outlet P2, the P3, the P4 air flow rate that enter air bag 42 also can be along with changes, so that the variation of the contact force F of friction lining 42 and friction disc 41, the change of F power can increase or reduce friction sheet to the resistance of friction disc, reaches to regulate to unreel film and roll up the parameters such as 1 tension force, speed.
Because this friction lining belongs to consumable accessory, material mostly is nylon, and the composite materials such as polyurethane, this friction lining change frequently, have in the process of abrasion a large amount of dust, smell to produce; Friction lining and friction disc belong to mechanical type contact in addition, easily produce certain vibrations when work.The existence of above-mentioned shortcoming has increased the difficulty, space purifying degree of plant maintenance, additional vibration influence to the tension force that unreels the film volume etc.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of single armed rolling cutting machine hai roll tenslator is provided, have advantages of tension stability, easy to operate, do not produce pollution.
The utility model has adopted following technical scheme: comprise the tensioner from the rotating shaft transmitting torque to the rolling film and the tension control assembly thereof that are fixed on rolling film volume rotating shaft one end and roll up, described tensioner comprises coupler and the power-transfer clutch of mutual series connection; The input end of coupler is connected with the rotating shaft of rolling film volume; Power-transfer clutch is magnetic-powder clutch, and its mouth is fixed on the equipment supporter; Described tension control assembly is carried exciting current to power-transfer clutch.
Adopt the coupler can be when changing parent roll, the disconnection that makes things convenient for parent roll axle and power-transfer clutch be connected.Because the friction of the magnetic of the inner section of magnetic-powder clutch produces resistance, work is that certain heat generation is arranged, and a preferred version of the present utility model is to be provided with air cooling equipment in the power-transfer clutch outside.
Described coupler is cross coupler.
The utility model adopts magnetic-powder clutch as tensioner, and its advantage is that exciting current and transmitting torque are substantially linear.In the situation that can transmit certain torque with slippage is irrelevant.Have fast response time, simple in structure, pollution-free, noiselessness, without advantages such as impact endurance test shocks, and safeguard easily.
Description of drawings
Fig. 1 is existing single armed rolling cutting machine hai roll tenslator structural representation.
Fig. 2 is the utility model structural representation.
The specific embodiment
By shown in Figure 2, the utility model tensioner comprises coupler 6 and the power-transfer clutch 7 of mutual series connection; The input end of coupler 6 is rolled up 1 rotating shaft 12 with the rolling film and is connected; Power-transfer clutch 7 is magnetic-powder clutch, its input end 8 and coaxial connection of coupler 6 mouths, and the mouth of power-transfer clutch 7 is fixed on the equipment supporter; Described tension control assembly 5 is carried exciting current to power-transfer clutch 7.Power-transfer clutch 7 outsides are provided with air cooling equipment 9, and this air cooling equipment 9 can be fan.
Coupler is cross coupler.
Its principle of work is as follows: unreel film volume 1 and rotate under the driving of rolling film volume motor, rotate by rotating shaft 12 and coupler 6 band dynamic clutch 7.Because the variation of unwinding tension, can signal be passed to tension control assembly 5 by the tension pick-up that is installed in the equipment, the size of current that tension control assembly 5 is regulated magnetic-powder clutch automatically according to the variation of tension force is controlled the quantity of magnetic, increase or reduce magnetic-powder clutch rotational resistance F resistance thereby reach, come balance to unreel the parameters such as the tension force of film volume and speed by this resistance.
