Description

End face slippage power controllable type Scroll

Technical field

The utility model relates to a kind of Scroll, particularly a kind of end face slippage power controllable type Scroll.

Background technology

At present, the structure of Scroll is referring to Fig. 2 and Fig. 3, it has generally comprised mandrel and volume core, and the both sides end face of volume core is provided with friction lining, and volume core and friction lining all are sleeved on the mandrel, the right side of mandrel also is set with and compresses block, holddown spring is housed compressing between block and the rightmost side friction lining.The stressing conditions of Scroll volume core is referring to Fig. 4, and what A order among Fig. 4 overlooks stressing conditions referring to Fig. 5, and wherein F represent adhesive tape to rolling up the reverse drag power of core, f represent friction lining to roll up core friction force, N represents the positive pressure of horizontal direction, rotation direction is referring to shown in Figure 4.It is that friction force f does positive work traction drive adhesive tape winding that Scroll rotates rolling, and this friction force f is referred to as end face slippage power.Existing Scroll exists following defective: because the positive pressure N spring application of existing volume core and friction lining, in the Scroll wrapup procedure, because spring is non-adjustable, be that positive pressure N is constant, be that moment of torsion ω is constant, and adhesive tape becomes big along with the continuous take-up diameter of adhesive plaster is continuous on the Scroll, adhesive plaster rolling linear velocity reduces, according to power W=FV, W is constant, and along with reducing of linear velocity V, the application force between adhesive plaster and the adhesive tape is the reverse drag power F increase of adhesive tape to the volume core, this has just caused adhesive tape to become tight by pine in wrapup procedure, and the adhesive tape quality is obviously descended.Therefore the size of end face slippage power f is decided by the adjusting of spring pressure N before rolling.Spring pressure N is difficult to be adjusted to desired value, even spring pressure N transfers very suitablely, so also can occur along with the variation adhesive tape of coil diameter becoming tight phenomenon by pine, can't guarantee the homogeneity of rolling, and rolling adhesive tape quality is descended; If regulate N too little, be the rolling effect that then do not have at wrapup procedure, promptly the friction force between friction lining and the volume core is not enough to drive adhesive tape winding; If regulate N too big, then roll up core and Scroll and friction lining and become one, along with the carrying out of rolling, the continuous change of adhesive tape is big, may be directly with the adhesive plaster tear fracture when serious.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of rolling good uniformity, the measured end face slippage of rolling adhesive tape matter power controllable type Scroll are provided.

Realize that the above-mentioned purpose technical scheme is: a kind of end face slippage power controllable type Scroll, include mandrel and volume core, the both sides end face of volume core is provided with friction lining, volume core and friction lining all are sleeved on the mandrel, the right side of mandrel also is set with and compresses block, also be set with on the described mandrel and connect block and intermediate slider, intermediate slider is clipped in the connection block and compresses between the block, have chute on the intermediate slider, compress the air cavity that has pin-and-hole on the block and communicate with pin-and-hole, the right side of mandrel has main airway longitudinally along longitudinal axis line of centers, and the right side of mandrel also has middle air flue radially, air cavity communicates with main airway by middle air flue, is provided with moving pin in the pin-and-hole.

Further, describedly compress block and the mandrel joint is provided with seal ring.

Further, described connection block is identical with the manufacturing materials of volume core.

After adopting technique scheme, have a lot of benefits: the utility model is changed the traditional spring application Scroll and the structure of friction lining, is improved to the structural shape with ventilation air flue.When therefore the utility model uses, communicate with the source of the gas of adjustable pressure by main airway, by automatically regulating air pressure, make the positive pressure of volume core and the suffered horizontal direction of friction lining can be along with the variation automatically regulating of coil diameter, thereby automatically regulating control end face slippage power, remedied the nonadjustable defective of the positive waterpower of prior art medi-spring level of compression direction, in the time of can not occurring during rolling when pine tight phenomenon, the utility model is simple in structure, product after rolling uncoiling power unanimity from outside to inside, the rolling good uniformity, rolling adhesive tape quality is good.
