Technical Field
The utility model relates to a chill roll for making membrane cooling process. Belongs to the technical field of film production equipment.
Background
The calender (calender) is composed of two or more rollers arranged in a certain form, and can be divided into cold pressing and hot pressing, wherein the cold pressing is suitable for materials which do not need to be heated, such as graphite films, graphite sheets, wave-absorbing materials, shielding materials, magnetic materials, nonferrous materials and the like. Hot pressing is a machine which presses and stretches rubber, silica gel or plastic into a film with a certain thickness and surface shape at a certain temperature and can carry out rubberizing on fiber curtain canvas or wirecord fabric. Calenders can be divided into two-roller calenders, three-roller calenders, four-roller calenders, five-roller calenders and the like according to the number of rollers; according to the arrangement mode of the rollers, the rollers can be divided into an L shape, a T shape, an F shape, a Z shape, an S shape and the like.
The film gets into cooling process from the calender back, and cooling process includes the cooling roller set that a plurality of rollers are constituteed, and current cooling roller set often sets up improper (including material, position etc.) at last cooling roller or cooling roller set, can lead to the final heat shrinkage percentage of film not up to standard, influences product quality.

Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Referring to fig. 1-2, the present invention relates to a cooling roller for a film-making cooling process, comprising a roller 1, a first bevel gear 2, a second bevel gear 3, a third bevel gear 4, a fourth bevel gear 5, a first lead screw 6, a shaft 9 and a second lead screw 10,
the first bevel gear 2 and the second bevel gear 3 are oppositely and fixedly arranged at two ends of the shaft 9; the third bevel gear 4 is fixedly arranged at the rear end of the first lead screw 6, the fourth bevel gear 5 is fixedly arranged at the rear end of the second lead screw 10, the first bevel gear 2 is meshed with the third bevel gear 4, and the second bevel gear 3 is meshed with the fourth bevel gear 5;
a first nut 11 is fixedly arranged at one end of the roller 1, the first nut 11 is sleeved on the first screw rod 6, a second nut 12 is fixedly arranged at the other end of the roller 1, and the second nut 12 is sleeved on the second screw rod 10;
the end of the shaft 9 is provided with a handle 8, and the shaft 9 can be rotated by rotating the handle 8.
All be provided with safety cover 7 on first lead screw 6 and the second lead screw 10, safety cover 7 prevents that debris from influencing the going on of lead screw drive.
The working principle is as follows:
the rotating handle 8 enables the shaft 9 to rotate, the shaft 9 drives the first bevel gear 2 and the second bevel gear 3, the first bevel gear 2 drives the third bevel gear 4 to rotate, the second bevel gear 3 drives the fourth bevel gear 5 to rotate, the third bevel gear 4 drives the first lead screw 6 to rotate, the first lead screw 6 drives the first nut 11 to move back and forth, the fourth bevel gear 5 drives the second lead screw 10 to rotate, the second lead screw 10 drives the second nut 12 to move back and forth, under the combined action of the first nut 11 and the second nut 12, the roller 1 can move back and forth, tensioning of a film is facilitated, and the final heat shrinkage rate of the film is up to the standard.
The film is an important commodity flexible packaging material, the heat shrinkage rate of the film has important influence on the aesthetic property of commodity packaging, and the proper heat shrinkage rate can make the packaging compact and avoid the phenomenon that the film is folded due to unbalanced shrinkage.
High temperature film from the calender gets into the cooling roller set cooling, and in order to make the final heat shrinkage percentage of film up to standard, the last roller of cooling roller set need adjust suitable position, adopts the technical scheme of the utility model can adjust the position of roller 1 as required to make the final heat shrinkage percentage of film up to standard, guaranteed product quality.
The utility model discloses a roller 1 adopts the rubber roller, and this kind of material can not influence the final heat shrinkage percentage of film.
In the above embodiments, the present invention has been described only by way of example, but various modifications may be made by those skilled in the art after reading the present patent application without departing from the spirit and scope of the invention.
