the water filling connecting piece is arranged at one end of the roller main body and is communicated with the strip-shaped air bags.
Furthermore, the elastic part is a spring with one end connected with the strip-shaped groove and the other end connected with the strip-shaped air bag.
Further, each strip-shaped groove is arranged along the axial direction of the roller main body, and is arranged at intervals in the circumferential direction of the roller main body.
Further, each of the strip-shaped grooves is arranged along the circumferential direction of the roller body, and each of the strip-shaped grooves is arranged at intervals along the axial direction of the roller body.
Further, each strip-shaped groove is arranged obliquely to the cross section of the roller main body.
Furthermore, the water filling connecting piece comprises a connector and guide pipes with the same number as the strip-shaped air bags, and each guide pipe is communicated with the connector.
Furthermore, the connector is a pipe body with an external thread.
The invention has the beneficial effects that: through set up a plurality of bar gasbags that can deform on the outer wall of roller main part, fill the cooling water to the bar gasbag, can strengthen the roller to plastic film's cooling effect.
Drawings
FIG. 1 is a schematic structural diagram of a roller according to an embodiment of the present invention.
In the figure: 10-roller body, 11-strip groove, 20-strip air bag, 30-elastic piece, 41-connector and 42-conduit.
Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
As shown in figure 1, the roller of the invention comprises a roller main body 10, a plurality of strip-shaped air bags 20 and a water filling connecting piece. The outer wall of the roller main body 10 is provided with a plurality of strip-shaped grooves 11, each strip-shaped groove 11 is arranged along the axial direction or the circumferential direction of the roller main body 10, and the head end and the tail end of each strip-shaped groove 11 penetrate through the outer wall of the roller main body 10 respectively; each strip-shaped air bag 20 is arranged in each strip-shaped groove 11 and is connected with the corresponding strip-shaped groove 11 through a plurality of elastic pieces 30, and the length of each strip-shaped air bag 20 is equal to that of each strip-shaped groove 11; the water filling connecting piece is arranged at one end of the roller main body 10 and is communicated with each strip-shaped air bag 2.
According to the invention, the plurality of deformable strip-shaped air bags 20 are arranged on the outer wall of the roller main body 10, and the strip-shaped air bags 20 are filled with cooling water through the water filling connecting piece, so that the cooling effect of the roller on the plastic film can be enhanced. In addition, the strip airbag 20 may be deformed in that the contact force is flexible when the plastic films are in contact, and the area of indirect contact of the cooling water with the plastic films can be increased.
Specifically, the elastic member 30 is a spring having one end connected to the strip groove 11 and the other end connected to the strip airbag 20, and the elastic force of the spring can adapt to the deformation of the strip airbag 20.
For the distribution of the strip-shaped grooves 11, the strip-shaped grooves 11 can be arranged along the axial direction of the roller main body 10, and the strip-shaped grooves 11 are arranged at intervals around the circumferential direction of the roller main body, so that the strip-shaped grooves 11 surround the whole side surface of the roller main body 10; each of the strip grooves 11 may be provided along the circumferential direction of the roller main body 10, and each of the strip grooves 11 is provided at an interval along the axial direction of the roller main body 10 so that each of the strip grooves 11 covers the entire side surface of the roller main body 10.
Of course, in order to further increase the contact area between each strip-shaped airbag 20 and the plastic film, each strip-shaped groove 11 may be arranged obliquely to the cross section of the roller main body 11, so that each strip-shaped groove 11 is arranged on the side surface of the roller main body 10 in a threaded manner, and each strip-shaped airbag 20 is arranged on the side wall of the roller main body 10 in a threaded manner.
Specifically, the water filling connector comprises a connector 41 and guide tubes 42 with the same number as the strip-shaped air bags 20, and each guide tube 42 is communicated with the connector 41.
