Technical field
The utility model relates to a kind of load transfer device, particularly can keep the reliable and stable permanent friction force en plaque raw material frictional transporting mechanism of feed status, belongs to the load transfer device technical field.
Background technology
At present, the en plaque raw material is normal to use a kind of friction running roller pay-off to carry, the formation of described friction running roller pay-off as shown in Figure 2, it comprises feed bin 4, bottom plate 5, spring 15, feeding running roller 1 and pressure roller 2.Before the feeding, the feed bin inside repeated en plaque raw material 3 of packing into, compressed at the effect lower spring 15 of en plaque raw material, pressure roller and friction feeding roller wheel are positioned at en plaque raw material top.In the automatic feeding process, the positive pressure that utilizes spring to produce, produce friction force when making the rotation of friction feeding running roller and between the en plaque raw material, utilize this friction force that a slice en plaque raw material that comes the top is twisted with the fingers out feed bin, thereby realize relying on the friction force automatic feeding.The shortcoming of this tradition friction running roller pay-off is: in whole feeding process, the elastic force of spring is depended in the generation of friction force, along with the size of the variation friction force of elastic force also can change, when raw material for a long time, amount of spring compression is big, positive pressure and friction feeding running roller are also big to the friction force of raw material, at this moment the phenomenon that raw material send more may occur; Carrying out along with the automatic feeding process, raw material is fewer and feweri, the amount of compression of spring is more and more littler, positive pressure and feeding running roller also reduce the friction force of raw material thereupon, it is last because friction force is too little, the phenomenon that may occur rubbing the feeding roller bye then can not twist with the fingers out raw material, so feeding unstable working condition.
The utility model content
The purpose of this utility model is the drawback at prior art, provides the friction force that guarantees the feeding running roller in a kind of feeding process invariable, thereby makes the permanent friction force en plaque raw material frictional transporting mechanism of feeding stable working state failure-free.
Problem described in the utility model realizes with following technical proposals:
A kind of permanent friction force en plaque raw material frictional transporting mechanism, it comprises feed bin, bottom plate, friction feeding running roller and pressure roller, bottom plate is positioned at feed bin, friction feeding running roller and pressure roller are positioned at feed bin top, special feature is: described device is provided with the constant voltage material carrying mechanism, the constant voltage material carrying mechanism is arranged on the feed bin bottom, the constant voltage material carrying mechanism comprises cylinder, change-over valve, reducing valve, pneumatic line and source of the gas, described pneumatic line connects source of the gas, reducing valve, change-over valve and cylinder, and cylinder rod connects bottom plate.
Above-mentioned permanent friction force en plaque raw material frictional transporting mechanism, described cylinder rod end is provided with bracket, and bracket is captiveed joint with bottom plate.
Above-mentioned permanent friction force en plaque raw material frictional transporting mechanism is provided with pneumatic triplet between described source of the gas and the reducing valve.
Above-mentioned permanent friction force en plaque raw material frictional transporting mechanism, the exit of described source of the gas arranges switch valve.
Above-mentioned permanent friction force en plaque raw material frictional transporting mechanism, change-over valve is the two-position five-way solenoid directional control valve.
The utility model improves the problem of unstable working condition at the influence that existing friction running roller automatic feeding is changed by spring force, replace spring with the constant voltage material carrying mechanism of being formed by cylinder and pneumatic element, the positive pressure that the constant voltage material carrying mechanism produces is not subjected to what influence of raw material in the feeding process, thereby guaranteed to send in the feeding process friction force of friction material roller wheel constant, and then guaranteed that the automatic feeding process is reliable and stable and carry out.In addition, constant voltage material carrying mechanism of the present utility model, the positive pressure that its cylinder produces can also carry out step-less adjustment by the reducing valve in the pneumatic circuit, can produce different positive pressures and feeding friction force as required, makes pay-off Applicable scope more extensive.

The specific embodiment
Referring to Fig. 1, the utility model comprises feed bin 4, bottom plate 5, friction feeding running roller 1 and pressure roller 2.Bottom plate is positioned at feed bin, the pile en plaque raw material 3 to be conveyed of packing in the feed bin, and the friction feeding running roller 1 and the pressure roller 2 that are arranged on feed bin top press on en plaque raw material top.Be provided with the constant voltage material carrying mechanism in the feed bin bottom, the constant voltage material carrying mechanism comprises cylinder 8, change-over valve 9, reducing valve 10, pneumatic line 12 and source of the gas 14, by pneumatic line source of the gas, reducing valve, change-over valve and cylinder is formed gas circuit and is connected.In order to realize stablizing retainer, on the top of cylinder rod 7 bracket 6 is set, the affixed bottom plate of bracket.For the source of the gas of the low and pressure stability of moisture and Dust Capacity is provided to cylinder, between source of the gas 14 and reducing valve 10, be provided with pneumatic triplet 11.Automatically control for ease of realization feeding process, change-over valve 9 is selected the two-position five-way solenoid directional control valve for use, and the mode of operation of this solenoid directional control valve is normally closed.In addition, also be provided with switch valve 13 in source of the gas 14 exits.
Still referring to Fig. 1, the utility model working process is as follows: the right position of change-over valve 9 energising is connected, and cylinder rod 7 drives bottom plates 5 and falls, the repeated en plaque raw material 3 of packing in the feed bin 4; Position, a change-over valve outage left side is connected, cylinder 8 produces power upwards by cylinder rod to bottom plate and raw material, during 1 rotation of friction feeding running roller and stock yard produce friction force, utilize this friction force that a tablet raw material is topmost twisted with the fingers out feed bin, thereby realize the automatic feeding of friction running roller.Because the positive pressure that cylinder produces can guarantee substantially constant by reducing valve 10, so this device can be realized constant positive pressure and the friction force of automatic feeding.The utility model replaces spring to produce positive pressure with the constant voltage material carrying mechanism, overcome since in the feeding process because raw material reduces the change in friction force that causes, thereby having guaranteed that the automatic feeding process is reliable and stable carries out.The positive pressure that cylinder produces can also carry out step-less adjustment by regulating reducing valve, produces different positive pressures and feeding friction force as required, makes pay-off Applicable scope more extensive.
