[0057] The left and right sides of the contact scraper 322 are set as two inclined and intersecting slopes, the two connecting rods 323 are located on the front and rear sides of the bottom of the contact scraper 322 respectively, and the support spring 324 is located on the contact scraper 322. between the bottom of the scraper 322 and the top of the bottom plate 321 .

[0058] The front and rear sides of the inner side of the mounting seat 33 are both provided with protrusions, and the front and rear sides of the bottom plate 321 are provided with grooves adapted to the protrusions.

[0059] The grooves provided on the bottom plate 321 are adapted to the protrusions on the inner side of the mounting seat 33. When the bottom plate 321 and the inner side of the mounting seat 33 are installed, the contact scraper 322 can It is stably connected to the mounting seat 33 to increase the connection stability between the two.

[0060] The upper pressing roller 21 is located directly above the lower pressing roller 22, and the gap between the upper pressing roller 21 and the lower pressing roller 22 is used for the passage of the anti-stick air mold material, so that the anti-adhesive air mold material is subjected to Pressed and tightly fitted, two first drive roller groups 4 arranged symmetrically up and down, two heating assemblies 5 and a second drive roller group 6 arranged symmetrically up and down are respectively arranged between two sides of the inner wall of the main frame 1 .

[0061] The two first drive roller sets 4 are respectively used to convey the upper and lower material layers to the lamination structure 2, while the second drive roller set 6 is used to convey the middle layer material, and the heating assembly 5 is mainly used to carry out the material layer. Heat treatment to make it tighter when pressing.

[0062] The working principle of the calendering device for preparing the anti-stick gas mold material provided by the present invention is as follows:

[0063] In normal use, the upper layer material and the lower layer material are respectively installed on the two first drive roller sets 4, and then the middle layer material is installed on the second drive roller set 6, between the first drive roller set 4 and the second drive roller Under the operation of the group 6, the three material layers can move to the position of the pressing structure 2, and when passing through the position of the heating assembly 5, they are rapidly heated and processed, and finally the upper pressing roller 21 in the pressing structure 2 and the lower pressing Under the cooperative extrusion action of the roller 22, the material layers are effectively squeezed together;

[0064] When the material layer is squeezed so that the adhesive inside flows out to the outside of the lower pressing roller 22, by starting the blower 351 at this time, cold air can be generated and transported to the exhaust duct 352, so that the cold air can pass through the exhaust air. The duct 352 is blown to the outside of the lower pressing roller 22, and when the lower pressing roller 22 rotates, it can drive the adhesive adsorbed on the outside to move to the position of the exhaust duct 352, and under the action of cold air, the adhesive can be quickly cooled and air-dried When the dried adhesive moves to the position of the contact blade 322 with the lower pressure roller 22, under the action of the contact blade 322, the adhesive can be removed from the outside of the lower pressure roller 22 and be removed. The adhesive that comes down falls directly on the bottom of the inner wall of the box body 31, and then cleans it up by opening the box door on one side of the box body 31;

[0065] If the adhesive adsorption force is too strong, and the contact scraper 322 cannot remove it, the dried adhesive can press down the contact scraper 322 to move, and the contact scraper 322 drives the connecting rod 323 to the mounting seat. 33 shrinks inside, and the contact scraper 322 moves downward at this time, which will not affect the rotation of the lower pressure roller 22, so that the lower pressure roller 22 continues to rotate downward to ensure that the contact scraper 322 does not hinder the lower pressure roller 22.

[0066] Compared with the related art, the calendering device for the preparation of the anti-stick gas mold material provided by the invention has the following beneficial effects:

[0067] By arranging the cleaning structure 3 outside the lower pressing roller 22, it is mainly used for cleaning the adhesive outside the lower pressing roller 22, wherein by arranging the retractable scraper assembly 32 and the cooling assembly 35 at the lower position of the lower pressing roller 22, They are respectively used to quickly cool the adhesive to make it air dry, and then remove it by the scraper assembly 32, so as to realize the rapid removal of the adhesive, and avoid being adsorbed on the outside of the lower pressure roller 22 for a long time, which will affect the normal use of the lower pressure roller 22. , so that the pressing structure 2 has an automatic cleaning function, which is safer and more worry-free during use.

[0069] Please refer to Image 6 , based on the first embodiment of the present invention, a calendering device for the preparation of anti-adhesive air mold materials, the second embodiment of the present invention provides another calendering device for the preparation of anti-adhesive air mold materials, wherein the second embodiment It will not prevent the independent implementation of the technical solution of the first embodiment.

[0070] Concretely, the difference of the calendering device for the preparation of another anti-stick gas mold material provided by the present invention is:

[0071] The electromagnet 7 is mounted on the top of the bottom plate 321, and the metal sheet 8 is mounted on the bottom of the contact scraper 322. After the electromagnet 7 is energized, the metal sheet 8 can be attracted downward.

[0072] The electromagnet 7 is externally connected with a power supply, and its use is controlled by an external switch. When the cleaning structure 3 is in normal use, the electromagnet 7 is in a power-off state, so that the contact scraper 322 can be effectively attached to the bottom of the lower pressure roller 22, and when it is not When it is necessary to use the cleaning structure 3 to clean the adhesive on the outside of the lower pressure roller 22, the switch of the electromagnet 7 can be pressed, so that the electromagnet 7 can generate a magnetic force after being energized, and then the metal sheet 8 can be attracted downward, while the metal sheet 8 can be attracted downward. It is fixedly installed with the bottom of the contact scraper 322, so as to drive the contact scraper 32 to move downward at the same time, so that the top of the contact scraper 322 can be separated from the outside of the lower pressure roller 22, so that the lower pressure roller 22 is in a retracted state, thereby reducing the For the frictional effect on the outside of the lower pressure roller 22, the electromagnet 7 can be turned off when cleaning is required next time, so that the metal sheet 8 is no longer attracted by the magnetic force, and under the elastic force of the support spring 324, the contact scraper 322 can be reset, However, by arranging the electromagnet 7 and the metal sheet 8, the automatic adjustment of the use state of the contact blade 322 can be realized, and the contact blade 322 can be retracted when not in use to reduce friction with the lower pressing roller 22 and protect both. function, and make the contact scraper 322 more flexible and convenient in use.
