Abstract
The utility model discloses a compression roller for preparing PET frosted plate, wherein the compression roller can change the surface shape of the PET plates and endow the PET plates with a frosted visual effect. The compression roller comprises a roller body and rotating shafts arranged on two sides of the roller body, wherein the two lateral end faces of the roller body and the end covers respectively arranged on the rotating shaft on corresponding side in a penetration manner are sealed together; the roller body, the end covers on two sides and the inside of the rotating shafts are provided with a connected cooling channel; a plurality of granular embossments are evenly arranged on the rolling surface of the roller body. The compression roller changes the surface shape of the PET plates during the process of molding the PET plates, so as to endow the PET plates with the frosted visual effect, thus, the material cost is reduced greatly, moreover, the original production technology is free from being changed, so that the production cost is lowered greatly.
Description
Technical field
The utility model relates to the press-roller device that is used for the PET sheet metal forming in the PET production line, refers more particularly to the pressure roller in press-roller device.
Background technology
In the process of producing PET sheet material,, in order to allow PET sheet material possess the visual effect of frosted, normally, by changing the way of raw-material formula, namely add the material of a certain proportion of change translucent effect on the basis of original formula.So not only increased material cost, and, also to adjust original production technology, make production process more complicated, increased production cost.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of surface configuration that can change PET sheet material to make PET sheet material have the pressure roller for the preparation of PET frosted plate of frosted visual effect.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: for the preparation of the pressure roller of PET frosted plate, comprise roll body and the rotating shaft that is arranged on the roll body both sides, the both sides end face of roll body seals mutually with the end cap that is located in a corresponding side rotating shaft, be provided with the cooling duct of perforation in the end cap of roll body and both sides and rotating shaft, evenly be provided with some graininess projections on the roll surface of roll body.
The height of described graininess projection is between 0.5～2 millimeter; Spacing between adjacent particle shape projection is between 1～3.5 millimeter.
The concrete set-up mode of described cooling duct is: roll body is along circumferentially evenly being provided with several axial arranged Cooling Holes, be respectively arranged with axial inflow and outflow hole in the rotating shaft of both sides, the rotating shaft of both sides, near the roll body place, along circumferentially being provided with several, with corresponding inflow and outflow hole, communicating and outwardly open intercommunicating pore, is provided with the cavity that is communicated with the intercommunicating pore in Cooling Holes and a corresponding side rotating shaft respectively on a side end face of described end cap.
Described Cooling Holes is screwed hole.
Described Cooling Holes is not more than 1/2nd of roll body radius from the distance of roll surface.
The beneficial effects of the utility model are: pressure roller described in the utility model, by change the surface configuration of PET sheet material in PET sheet material is carried out forming process, make PET sheet material have the frosted visual effect, thereby greatly reduce material cost, and, owing to need not to change original production technology, thereby greatly reduce production cost.In addition, height and the density of graininess projection are moderate, make PET sheet material have frosted visual effect preferably; Cooling duct simple in structure, install very convenient; And,, because Cooling Holes is screwed hole and close roll surface, greatly improved the cooling effect of roll surface.

The specific embodiment
, below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail:
as shown in Figure 1, pressure roller for the preparation of PET frosted plate described in the utility model, comprise: roll body 1 and the rotating shaft 2 that is arranged on roll body 1 both sides, the both sides end face of roll body seals (because the sealing syndeton is the ordinary skill in the art mutually with the end cap 3 that is located in a corresponding side rotating shaft, not shown in FIG.), be provided with the cooling duct of perforation in the end cap 3 of roll body 1 and both sides and rotating shaft 2, its concrete set-up mode is: roll body 1 is along circumferentially evenly being provided with several (being generally 8～16) axial arranged Cooling Holes 12, be respectively arranged with axial inflow and outflow hole 21 in the rotating shaft 2 of both sides, the rotating shaft 2 of both sides is communicating and outwardly open intercommunicating pore with corresponding inflow and outflow hole 21 along circumferentially being provided with several (being generally 4～8) near roll body 1 place respectively, be provided with the cavity 31 that is communicated with the intercommunicating pore in Cooling Holes 12 and a corresponding side rotating shaft 2 on one side end face of described end cap 3, evenly be provided with some graininess projections 11 on the roll surface of roll body 1, the height of graininess projection 11 is between 0.5～2 millimeter, spacing between adjacent particle shape projection 11 is between 1～3.5 millimeter.In the present embodiment, described Cooling Holes 12 is screwed hole, and Cooling Holes 12 is not more than 1/2nd (usually less than 1/3rd) of roll body 1 radius from the distance of roll surface.
During practical application, usually be provided with swivel joint in the rotating shaft 2 of roll body 1 both sides, the swivel joint of both sides is connected with the high-pressure cooling water source with reversal valve by water pipe respectively.
During use, only need the opening high pressure cooling water source, cooling water is injected in the Cooling Holes 12 of roll body 1 through inflow and outflow hole 21 and the cavity 31 in end cap 3 of water pipe, swivel joint and a side rotating shaft 2, by inflow and outflow hole 21, swivel joint and the water pipe outflow of the cavity 31 in opposite side end cap 3, rotating shaft 2; And,, by setting the commutating period of reversal valve, change at set intervals the direction of current,, to reduce the roll surface temperature difference everywhere, make roll surface temperature everywhere more even.
