Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary intended for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Referring to fig. 1-3, the present invention provides an embodiment: a flame-retardant film extrusion mechanism comprises a base 1, wherein a support frame 2 is arranged on the base 1, and an extrusion mechanism 3 and a forming roller 10 are arranged on the support frame 2; the squeezing mechanism 3 comprises a bracket 30 and a pressure roller 31 arranged on the bracket 30; a guide rod 36 and a screw 34 are further arranged on one surface, away from the pressing roller 31, of the bracket 30, and the screw 34 penetrates through the bracket 30 and then is connected with a nut 33; the outside of guide bar 36 is still overlapped and is equipped with spring 35, the one end of spring 35 is supported on support 30, just the other end of spring 35 with support frame 2 is supported.

Through the above manner, firstly, the spring 35 is sleeved on the guide rod 36, and then the screw 34 and the guide rod 36 simultaneously penetrate through the support frame 2, wherein the screw 34 penetrates through the support frame 2 and then is connected with the nut 33, so that the assembly of the support frame 2 and the extrusion mechanism 3 can be realized; then, the forming roll 10 is installed below the pressing mechanism 3.

In conclusion, the nut 33 is tightened to drive the bracket 30 to move upwards, so that the gap between the forming roller 10 and the pressing roller 31 can be adjusted; therefore, the equipment can process the lines of the flame-retardant films with different thicknesses;

meanwhile, when the thickness of the flame-retardant film is changed, the spring 35 contracts to enlarge the gap between the forming roller 10 and the press roller 31, so that the flame-retardant film smoothly passes through the forming roller 10 and the press roller 31; in addition, the spring 35 is arranged to rapidly reset the gap between the forming roller 10 and the press roller 31 after the gap is changed, so that after the flame-retardant film passes through the forming roller 10 and the press roller 31, the press roller 31 can transfer the lines on the forming roller 10 to the passing flame-retardant film under the action of the spring 35.

Because the quantity of guide bar 36 is two, two guide bar 36 symmetry set up the both sides of screw rod 34, and every guide bar 36 on all overlap and have spring 35 for the both ends atress of support 30 is balanced, and can also guarantee that support 30 is more steady up-and-down slip.

In order to facilitate the installation and replacement of the compression roller 31, fixing plates 32 are further arranged at two ends of the bracket 30, the compression roller 31 is rotatably installed on the bracket 30 by penetrating bolts through the fixing plates 32, and therefore, the compression roller 31 can be installed and replaced by disassembling and assembling the fixing plates 32.

On the basis of the scheme, as the medium flow channel 11 is arranged inside the forming roller 10, the heat medium can be introduced into the forming roller 10, so that the film can be softened when passing through, and the texture on the forming roller 10 is further promoted to be transferred to the film; wherein, the heat medium can be hot oil.

Furthermore, because the support frame 2 is also provided with the auxiliary roller 8, and the auxiliary roller 8 is also internally provided with the medium flow channel 11, the medium can enter the auxiliary roller 8, wherein the medium entering the auxiliary roller 8 is a cold medium, such as water.

Furthermore, because both ends of the forming roller 10 are connected and communicated with the first container 6 through the pipeline 5, and both ends of the auxiliary roller 8 are also connected and communicated with the second container 7 through the pipeline 5, the cold and hot media are separated, and the cold medium in the auxiliary roller 8 can be used for absorbing heat on the film material to promote the film material to be hardened.

In summary, due to the arrangement of the two containers, the heat medium is separated from the cold medium, and the heat medium and the cold medium are respectively made to circularly flow in the corresponding containers. Therefore, the equipment can reduce the problem that the film material is stuck together due to the heat concentration after the film material is rolled while the film material is molded.

In addition, the first container 6 and the second container 7 are both provided with pump bodies, and the side surface of the support frame 2 is also provided with a control box 4 for mounting control equipment. Due to the arrangement of the control box 4, the controlled components can be integrated in the control box 4, so that the use of a user is facilitated.

Because the two ends of the forming roller 10 and the auxiliary roller 8 are in shaft-pin connection with the support frame 2 through the shaft-pin rod 9, the forming roller 10 and the auxiliary roller 8 can freely rotate on the support frame 2, and the medium flow channel 11 also penetrates through the shaft-pin rod 9, so that a rotary joint can be arranged on the end surface of the shaft-pin rod 9, and the forming roller 10 and the auxiliary roller 8 are ensured not to be interfered when rotating; wherein the rotary joint may be a quick joint.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
