Abstract

The utility model relates to a rubber roller. The rubber roller comprises a roller body and two roller shafts which are supported on two ends of the roller body, wherein the roller body consists of an inner barrel and an outer barrel which is sleeved on the inner barrel, the outer circumferential surface of the inner barrel is provided with a helical fluid groove, the fluid groove and the inner wall of the outer barrel combine to form a helical fluid passage, the roller shaft is supported on the end part of the inner barrel through a circular sealing plate which is arranged in the inner barrel, a main passage which extends along the axial direction is formed in the roller shaft, and a branch passage which is arranged between the fluid passage and the main passage is formed in the roller shaft, the circular sealing plate and the inner barrel. The rubber roller has the advantages that the liquid does not play under the high-speed rotation, and the temperature on the surface of the roller is uniform, and the production efficiency can be effectively improved.

Description

A kind of plastic roll roller

Technical field

The utility model relates to a kind of plastic roll roller, and this plastic roll roller can be used as for the hot-rolling of gluing or chill roll and is applied to the amenities production equipment.

Background technology

The plastic roll roller is applied in the amenities production equipment as hot-rolling or chill roll usually, hot-rolling mainly is for substrate surface is heated gluing, chill roll then is for the base material behind the gluing is cooled off, the common feature of hot-rolling and chill roll is that equal tool need to arrange mobile heat-conducting medium among both, be generally deep fat or cooling water, existing plastic roll roller is that liquid storage cylinder is set in roll body, liquid storage cylinder is provided with feed pathway and the liquid outlet channel on the roll shaft that is positioned at the plastic roll roller, thereby form the circulatory system with the feed flow source, because liquid storage cylinder is arranged at the axial middle part of roll body, the liquid play can occur when plastic roll roller high speed rotating, cause the vibrations of plastic roll roller and roll surface temperature skewness, therefore, existing plastic roll roller can only in tick-over, have a strong impact on production efficiency.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, and a kind of realize running up lower liquid not play, the uniform plastic roll roller of roll surface temperature are provided.

The purpose of this utility model realizes by following technical solution:

A kind of plastic roll roller, comprise roll body and two roll shafts that are bearing in the roll body two ends, it is characterized in that: described roll body is comprised of inner core and the urceolus that is sheathed on the inner core, described inner core outer peripheral face is formed with spiral fluid slot, described fluid slot and described outer tube inner wall surround spiral fluid passage, described roll shaft is bearing in described inner core end by the circular shrouding that is arranged in the inner core, be formed with in the described roll shaft along its axially extended mainstream channel, described roll shaft, be formed with the affluent channel that is connected between described fluid passage and the described mainstream channel in circular shrouding and the inner core.

Further, the outer peripheral face of described inner core is formed with the described fluid slot in four roads, is formed with the described affluent channel in four roads that is connected between corresponding fluid passage and the described mainstream channel in corresponding described roll shaft, circular shrouding and the inner core.

Further, the described affluent channel in four roads circle distribution centered by described roll shaft.

Further, described affluent channel is along the radially extension of described roll shaft.

Further, be provided with circular support plate in the described inner core, described roll shaft is located in circular support plate center.

The utlity model has following beneficial effect:

Between inner core and urceolus, form the spirality water stream channel, heat-conducting liquid is evenly distributed under the top layer of roll body, can realize running up of plastic roll roller like this, rotating speed can guarantee still that at 350 rev/mins liquid occurs without play, Effective Raise production efficiency, the vibrations that can avoid the plastic roll roller to cause because of play in addition, the service life of prolongation plastic roll roller; Heat-conducting liquid is evenly distributed under the top layer of roll body, can make the roll body surface temperature distribution even, prevents that base material from causing wrinklingly because of the inequality of being heated, and affects product quality.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is cutaway view of the present utility model.

Fig. 2 be among Fig. 1 A-A to cutaway view.

Fig. 3 is front view of the present utility model, removes urceolus so that internal structure to be shown.

The specific embodiment

Shown in seeing figures.1.and.2, a kind of plastic roll roller, comprise roll body and two roll shafts 4 that are bearing in the roll body two ends, roll body is comprised of inner core 1 and the urceolus 2 that is sheathed on the inner core 1, inner core 1 outer peripheral face is formed with the spiral fluid slot 11 that four roads are parallel to each other, fluid slot 11 surrounds spiral fluid passage 3 with urceolus 2 inwalls, roll shaft 4 is bearing in inner core 1 end by circular shrouding 6 and the circular support plate 5 that is arranged in the inner core 1, circular shrouding 6 is positioned at the outside, circular support plate 5 is positioned at the inboard, be formed with in the roll shaft 4 along its axially extended mainstream channel 41, roll shaft 4, be formed with the four road affluent channels 7 that are connected between fluid passage 3 and the mainstream channel 41 in circular shrouding 6 and the inner core 1, four road affluent channels 7 circle distribution centered by roll shaft 4, affluent channel 7 is along the radially extension of roll shaft 4, during work, the plastic roll roller is connected with fluid supply by the mainstream channel 41 on the roll shaft 4, forms Fluid Circulation.

The above, it only is preferred embodiment of the present utility model, so can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
