Abstract

The utility model discloses a kind of netting machine warp yarn expansion controller, including cam is opened a sluice gate, swing arm, connecting rod and voussoir installed in connecting rod top and the sheave being fixed on main warp let-off roller.When warp let-off line under control of the netting machine in warp let-off line cam, voussoir and the sheave of opening a sluice gate cam control separate, and main warp let-off roller steadily operates；After netting machine separates with warp let-off line cam, voussoir closes with sheave, produces resistance, the caused rotation due to inertia of warp let-off line roller is prevented, makes the amount of warp let-off line every time uniform, improves the stability of warp tension, so as to improve mesh sheet quality, outage is reduced, improves production efficiency.

Description

Netting machine warp yarn expansion controller

Technical field

The utility model belongs to netting machine technical field, the warp yarn expansion controller in more particularly to a kind of netting machine.

Background technology

Existing netting machine warp yarn expansion controller, it is to be closed by the brake wheel at main warp let-off roller both ends with hydraulic shunt pump And separately complete.When main warp let-off roller rotates, pay the brake cam on axle installed in orifice plate and do not contacted with roller, master cylinder not work Make, at this moment wheel cylinder opens, and roller runs well, and when stopping warp let-off line, orifice plate pays the cam and roller contact on axle, passes through pendulum Arm makes master cylinder convey big oil pressure to wheel cylinder, closes wheel cylinder, at this moment brake wheel is embraced by the hard rubber sheet on wheel cylinder, makes roller Do not operating.Keep the amount of each warp let-off line impartial, so as to control warp tension.The shortcomings that this device, is, in order that the warp let-off Roller can stop operating in time after the disconnection of warp let-off cam, and wheel cylinder sheet rubber need to give brake cam one very high adhesive force, The inertia of the frictional resistance and roller decomposited can be just set to maintain an equal level.Master cylinder and wheel cylinder work more than 20,000 times daily, easily make wheel cylinder Damage and failure.When damage is with failure, the cost of mesh sheet making, a period of time particularly before failure, brake are added The effect of (rotation for preventing the rolling of warp let-off line) is low, and at this moment the tension force of netting machine warp is just suddenly big or suddenly small, causes to shut down, broken string, Even produce useless net.Significantly increase the production cost of mesh sheet.

Utility model content

The purpose of this utility model for existing netting machine warp yarn expansion controller during equipment operation, open by warp Power control is unstable, and tension is inconsistent, causes the mesh sheet mesh size of production, net to tie the problems such as not tight, there is provided one kind makes warp rise Power is consistent, and net type, net tie the beautiful netting machine warp yarn expansion controller for effectively improving product quality.

The utility model is that solve above-mentioned technical problem by following technical proposals：

A kind of netting machine warp yarn expansion controller, by the cam being arranged in the Large Gear Shaft of left and right, installed in lining On swing arm, kinematic link, and voussoir unit installed in connecting rod top and the composition of the sheave on main warp let-off roller；On a left side Be respectively equipped with mounting hole on right lining, the bearing pin of the fixed swing arm of installation in mounting hole, after swing arm endoporus installation bearing with bearing pin Connection, swing arm one end installation roller bearing and cam contact, the other end are connected with connecting link pin with one end of connecting rod；Connecting rod it is another One end passes through left and right slot cover and voussoir pin shaft joint；The voussoir unit is arranged in the voussoir fixing axle on the cover plate of left and right, Centre is connected by connecting link pin with connecting rod；The sheave is fixed in the two end axles of main warp let-off roller by keyway with key.

Preferably, the cam is joined with bolts in the Large Gear Shaft of left and right to split formula, passes through regulating bolt Elasticity adjusts the actuation time of cam and roller.

Preferably, the connecting rod is monolithic construction.

Preferably, each voussoir unit is at least made up of a voussoir.

Preferably, a sheave is respectively installed additional at main warp let-off roller both ends, axially 1 bar groove is at least distributed with it.

Positive effect of the present utility model is：When voussoir and sheave contact, caused resistance and roller are used to Property force direction is on the same line, and in the opposite direction, therefore only to need less active force just roller can be made to stop in time, effect Substantially, rational in infrastructure, cost is cheap, is easily installed maintenance, can be found in time after voussoir group rapid wear, and changes or repair again Mill.So that the rotation uniform and stable of main warp let-off roller, so as to keep the uniformity of warp tension, so as to improve mesh sheet quality.

Embodiment

Name preferred embodiment, and become apparent from intactly illustrating the utility model with reference to accompanying drawing.

As shown in figure 1, the utility model is achieved through the following technical solutions a kind of netting machine warp tension control dress Put.The device includes the cam 1 being arranged in Large Gear Shaft, swing arm 2 and 3 bars of company and the voussoir of upper end on wallboard Unit 4 and sheave 5 form.

Described cam 1 is connected by bolts and is fastened in the Large Gear Shaft of left and right, with turning for Large Gear Shaft to split formula Move and rotate, pass through the time length of loose bolts adjustable cam 1 and roller contact.

Described swing arm 2 is connected on the bearing pin on the lining of left and right, one side installation roller and cam of swing arm 2 1 is contacted and produces swing, and action is transmitted to connecting rod 3 by another side with the swing of swing arm 2.

The described lower end of connecting rod 3 is connected by bearing pin with swing arm 2, and upper end is connected by bearing pin with voussoir unit 4, its work With being exactly that the action of cam 1 is transmitted to voussoir unit 4, voussoir unit 4 is set to separate or contact with sheave 5 within the regular hour. Connecting rod 3 is monolithic construction, can so improve the intensity of connecting rod 3, extend its service life.

Described voussoir unit 4, lower end, which is arranged on, to be fixed on the bearing pin on the cover plate of left and right, and centre passes through bearing pin and connecting rod 3 are connected, and when its effect is that connecting rod 3 moves down, voussoir unit 4 and sheave contact, prevents the rotation of sheave, actually hinder The only operating of main warp let-off roller, so as to ensure that each warp let-off line amount is unanimously uniform.Voussoir unit 4 is at least made up of a voussoir, Preferably 2-8.

Described sheave 5 is fixed on main warp let-off roller by key, is rotated and is stopped simultaneously with main warp let-off roller, it is to work as that it, which is acted on, Voussoir unit 4, which contacts, makes the very big resistance of generation, main warp let-off roller is shut down, so as to keep uniform the one of warp tension Cause.It is preferred that respectively installing a sheave additional at main warp let-off roller both ends, axially 1 bar groove, preferably 2-5 bars is at least distributed with it.

Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that These are merely illustrative of, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art Member can make numerous variations or repair to these embodiments on the premise of without departing substantially from principle of the present utility model and essence Change, but these changes and modification each fall within the scope of protection of the utility model.
