Abstract
The invention relates to a film traction and brake mechanism comprising a driving wheel arranged at the end of a traction roller and a brake pad in frictional contact with the wheel surface of the driving wheel, wherein the upper end of the brake pad is hinged with a piston rod of an air cylinder, and the lower end of the brake pad is rotationally arranged on a fixed rod; a cylinder body of the air cylinder is fixedly connected with a rack by virtue of a mounting plate; and the lower end of the brake pad is provided with a brake end which is upwards hooked, and the brake end is in contact with the wheel surface of the driving wheel. After the air cylinder drives the brake pad to rotate, the brake end of the brake pad is in frictional contact with the wheel surface of the driving wheel, so that the driving wheel is prevented from rotating, rapid brake is realized, the brake effect is good, and the condition that a film is tensioned because the traction roller rotates under the action of inertia is avoided.
Description
Technical field:
The present invention relates to technical field of mechanical equipment, particularly the packaging film feeding mechanism of wrapping machine.
Background technique:
In prior art, driving and the stopping of the traction gear of film all have by Electric Machine Control, there is film roll free-wheel and cause the situation that film tension is serious when Electric Machine Control traction gear stops.
Summary of the invention:
The above-mentioned shortcoming that the applicant exists for prior art, carries out studying and designing, provides a kind of packaging film feeding arrestment mechanism, and it has, and structure is simple, the feature of good braking effect.
In order to solve the problem, the present invention adopts following scheme:
A kind of packaging film feeding arrestment mechanism, comprises the driving wheel that is installed on take off roll end and to rub the braking plate touched with driving wheel wheel face, the upper end of braking plate and the piston rod of cylinder hinged, its lower end slewing gear is on fixing rod; The cylinder body of cylinder is connected by mounting plate and frame; The lower end of described braking plate is with the dog point of upwards crotch, and the wheel face of dog point and driving wheel touches.
Technique effect of the present invention is:
After the present invention adopts air cylinder driven braking plate to rotate, the wheel face friction of its dog point and driving wheel touches, and stops driving wheel to rotate, realizes fast braking, its good braking effect, avoid take off roll free-wheel to cause the situation of film tension.
Accompanying drawing illustrates:
Fig. 1 is three-dimensional structure diagram of the present invention.
In figure: 1, driving wheel; 2, cylinder; 3, mounting plate; 4, braking plate; 41, dog point; 5, fixing rod.
Embodiment:
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, the packaging film feeding arrestment mechanism of the present embodiment, comprises the driving wheel 1 being installed on take off roll end and the braking plate 4 touched with the friction of driving wheel 1 wheel face, the upper end of braking plate 4 and the piston rod of cylinder 2 hinged, its lower end slewing gear is on fixing rod 5; The cylinder body of cylinder 2 is connected by mounting plate 3 and frame; The lower end of braking plate 4 is with the dog point 41 of upwards crotch, and dog point 41 touches with the wheel face of driving wheel 1.
