The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 1-6, the pressure roller that can prevent bubble of the present utility model, comprise can be driven away from or near the support 2 of laminating points, the hollow square shaft 3 that two ends are fixedly connected with support, a plurality of couplings are set in the pressure roller sheet 4 on hollow square shaft and are arranged on the sebific duct 8 in hollow square shaft cavity, on described hollow square shaft 3 one sides, be formed with along its axially extended fluting 31, described pressure roller sheet 4 comprises to be determined circle 41 and the moving-coil 42 of determining the circle periphery rotatably is set, described Ding Quan center is formed with can mate the through hole 43 that is inserted in hollow square shaft, and be formed with the top tongue 44 that radially extends and can pass described fluting and contact with sebific duct in the through hole of described fixed circle.Described support is arranged on winding drum 5 tops by bracing frame, and 1 of described support and bracing frame are provided with cylinder 6 and guiding mechanism 7, and described guiding mechanism generally adopts the rail slide type design.During winding, to be positioned at the material to be fit that the bearing of trend of the place, point of contact of material 10 to be fit and winding drum and described top tongue locates with point of contact vertical for described pressure roller sheet.The adjacent setting of described cylinder and guiding mechanism, preferably the moving direction of support points to the axle center of winding drum.
Specifically, with casing ply, be wound up as example, pressure roller of the present utility model is arranged on the top of one section carcass drum, and while being wound around cord, this pressure roller integral body is promoted to be pressed in along two axis of guides the place, point of contact of drum surface and cord by two cylinders.This pressure roller closely is adjacent to be enclosed within on a hollow square shaft of fluting by 295 pressure roller sheets and two adjacent pressure roller sheets can relatively move, the top tongue is against on the sebific duct in hollow square shaft, while being filled with the gas of certain pressure in sebific duct, the vertical direction (fluting direction) that sebific duct will will surely enclose along hollow square shaft axis as spring ejects, on the cord that moving-coil is pressed in be wound around, in sebific duct, gas pressure is larger, the pressure of its pressure roller sheet is larger, being arranged on hollow square shaft inside has sebific duct to can be 295 pressure roller sheets to provide pressure (or claim spring force), and every pressure roller sheet can be separately under given supply gas pressure by point of contact along the drum diametric(al) to power, while making to be wound around cord along drum surface tangential direction incision laminating, each point all can be close to drum surface (or preorder twined cord face), prevent that cord nest when being wound around on drum surface from living gas and producing bubble.The number of pressure roller sheet is determined according to the width of cord, and the wider pressure roller sheet of cord is more.
As preferred version, described hollow square shaft be to be the square structure on circular arc limit with the fluting relative edge, the square structure that the through hole of described stator be and top tongue relative edge is arc-shaped edges.The vertical side that hollow square shaft is corresponding with through hole and rear arc limit, guaranteeing that the guiding that vertical side moves forward and backward the top tongue has increased the distance that moves up and down of determining circle simultaneously, improves squeezing effect.
Specifically, describedly surely enclose outer surface and the moving-coil internal circular surfaces is formed with respectively the ball road that cross section is semicircle, be arranged on a plurality of balls in ball road and be fixedly connected with both are rotatable.
As preferred version, described fixed circle and moving-coil all have the polyformaldehyde material, the quality that adopts this material can effectively reduce moving-coil and fixed circle guarantees its intensity simultaneously, and this material can effectively guarantee two adjacent pressure rollers surely enclose between sheet can not stick together and radially the changing of the relative positions slide freely, described moving-coil thickness is less than circle and placed in the middle setting of relatively fixed circle of determining simultaneously, retain vertically spacing between two moving-coils, be enough to guarantee the freedom that the moving-coil of each pressure roller sheet rotates.
As preferred version; be provided with the Teflon layer on the internal face of described hollow square shaft; the sebific duct be arranged in hollow square shaft is rubber tube; adopt the Teflon layer as separation layer; can effectively avoid the impact of hollow square shaft and rubber tube when protecting hollow square shaft, also be convenient to the insertion of sebific duct or extract.
Specifically, pressure roller of the present utility model also comprises the sebific duct outer hoop, the sebific duct plug, sealing gasket, gas port box nut etc., during assembling, first sebific duct is inserted in hollow square shaft, after the observation of fluting place determines that sebific duct has been inserted into bottom, square shaft hole (left end), at fluting, place shrivels sebific duct with instrument, be inserted in the pressure roller sheet piecewise on hollow square shaft, after cover is full, the round nut of screwing on, then sebific duct length more than needed is cut off, put the sebific duct outer hoop, after filling in sebific duct plug and sealing gasket, the gas port box nut of screwing on, tighten, sebific duct plug and sealing gasket are all compressed, prevent gas leakage, at air inlet, place is screwed into quick connector, connect after tracheae progressively to gas pressure roller sheet jack-up, piecewise with hand push pressure sensitivity feel pressure roller sheet elastic force, and inspection has or not gas leak phenomenon, after all are normal, assembly can be utilized the two end supports neck install on support.Rotate hollow square shaft for adjusting top tongue moving direction by point of contact, tighten the two ends fixture block after adjustment, do not allow hollow square shaft to rotate again rotation.During normal production, capable of regulating admission pressure as required, in order to obtain satisfied pressure roller sheet elastic force.
It is to be noted, above-described embodiment is to be wound up as with drum-type the exemplary illustrated that example is carried out, exhaust when pressure roller of the present utility model also attaches applicable to plane, only pressure roller need be arranged on and move horizontally support or pressure roller is arranged on to fixed support and will attaches material and thereunder move, as long as guarantee that laminating points is positioned at pressure roller below and makes the moving direction purpose that can realize the utility model vertical with material to be fit of top tongue, is not described in detail in this.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
