Description

Technical Field

[0002] Composite film is a multi-layer film structure composed of two or more different materials through lamination, co-extrusion and other processes.

[0003] The glue device is a key equipment in the production of composite films. Its role runs through the composite process of multi-layer structures. The glue device uses glue coating to bond two films. The existing glue device for composite film production will produce glue during use. The existing glue collection method is often to drop the excess glue directly into the glue storage box for reuse or to be collected and processed by the collection box.

[0053] The heating component 206 includes two heating rods 206a and multiple heat-conducting blocks 206b. The front and rear sides of the two heating rods 206a are respectively fixedly connected to the front and rear sides of the inside of the box 101h. The bottoms of the multiple heat-conducting blocks 206b are respectively fixedly connected to the front and rear sides of the surfaces of the two heating rods 206a. The tops of the multiple heat-conducting blocks 206b pass through the box 101h, the collection box 201a and the horizontal plate 201d in sequence, and are respectively fixedly connected to the bottoms of the two inclined plates 201b.

[0054] Specifically, the excess glue produced by the glue coating film will fall onto the two inclined plates 201b, then slide to the inside of the first filter screen 201c and enter the inside of the box 101h through the discharge port 201e. The rotation of the glue coating roller 101d can drive the second transmission block 202h to make the transmission belt 202g drive the first transmission block 202f to rotate, and the first transmission block 202f will drive the gear belt 202e through the second gear block 202c to rotate the first gear block 202b and the third gear block 202d, thereby causing multiple stirring rollers 202a to stir the glue inside the box 101h, and the bottom of the moving part 203m is in contact with the cross plate 201d and the top of the first filter screen 201c, and the front and rear sides of the moving part 203m are respectively in contact with the front and rear sides of the inside of the collection box 201a, and the rotation of the double reverse threaded rod 203h will cause the moving block 203j to move left and right repeatedly, thereby pushing the push rod 203k drives the moving part 203m to move left and right repeatedly, and the scraping part 204g is used to scrape off the excess glue on the edge after the two films are pressed together. The glue will enter the interior of the collection barrel 204c. The first filter screen 201c and the second filter screen 204d are used to filter the glue and intercept the solidified glue. The guide block 205c is high in the middle and has the bottom on the front and back sides, which makes it easy for the glue to flow to the position of the two liquid outlet holes 205b. The pusher plate 205m rotates with the rotating roller 205e through the matching block 205j. The bottom of the pusher plate 205m can be fitted with the top of the scraping block 205a through multiple elastic springs 205k, thereby pushing the glue to the right. The two heating rods 206a can heat the glue inside the box 101h, and the multiple heat-conducting blocks 206b will transfer the heat to the collection box 201a and the cross plate 201d, and the cross plate 201d will transfer the heat to the first filter screen 201c.

[0055] Furthermore, excess glue on the glue coating roller 101d will fall into the interior of the collecting box 201a, and the glued film will be transported to the right and the excess glue will be scraped off by the scraping block 205a. As the glue coating roller 101d rotates, the second movable block 205h will drive the movable belt 205g to rotate, and the movable belt 205g will rotate the first movable block 205f. The first movable block 205f will cause the rotating roller 205e to drive the matching block 205j and the pushing plate 205m to rotate. As the pushing plate 205m rotates to the right, under the elastic action of multiple elastic springs 205k, the bottom of the pushing plate 205m will fit with the top of the scraping block 205a, pushing the glue to the right, and entering the interior of the vertical pipe 205d from the two liquid outlets 205b through the guide block, and then entering the interior of the collecting box 201a.

[0056] The rotation of the glue coating roller 101d will cause the second transmission block 202h to rotate, the second transmission block 202h will cause the transmission belt 202g to rotate the first transmission block 202f, the first transmission block 202f will cause the second gear block 202c to drive the gear belt 202e to rotate, and the gear belt 202e will cause the first gear block 202b and the third gear block 202d to rotate, thereby causing multiple stirring rollers 202a to stir the glue inside the box 101h.

[0057] The rotation of the first gear block 202b will cause the first rotating block 203a to rotate and the rotating belt 203b to rotate. The rotating belt 203b will cause the second rotating block 203c to drive the rotating rod 203d and the first bevel gear 203e to rotate. The first bevel gear 203e will cause the double reverse threaded rod 203h to rotate. The double reverse threaded rod 203h will cause the moving block 203j to drive the push rod 203k and the moving part 203m to move left and right repeatedly. The glue entering the collection box 201a will be located inside the moving part 203m and on the top of the first filter screen 201c. The condensed glue will move left and right repeatedly. Under the heat transfer action of multiple heat conducting blocks 206b, the horizontal plate 201d drives the first filter screen 201c to heat the glue, so that the glue passes through the first filter screen 201c and enters the interior of the box body 101h through the discharge port 201e.

[0058] The excess glue on the front and back sides of the two pressed films will be scraped off by the scraper 204g and fall into the interior of the collecting bucket 204c. By running the motor 204e and the two heating plates 204f, the output end of the motor 204e drives the two heating plates 204f to rotate, and the two heating plates 204f heat the glue, so that the melted glue passes through the second filter 204d into the receiving port 204b, and returns to the interior of the box 101h from the conveying pipe 204a, thereby recovering the excess glue.

[0059] It should be noted that the heat conducting block 206b, the horizontal plate 201d, the first filter 201c and the second filter 204d are all made of metal, and the collection box 201a, the box body 101h and the collection barrel 204c are all made of heat-insulating materials.

[0060] The remaining structures are the same as those of Example 2.

[0061] Example 4 Reference Figures 1 to 10 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a multi-layer adhesive device for producing composite films.

[0062] When two films need to be bonded, the film to be coated with glue is first installed on the first discharge roller 101b, and the film to be bonded is installed on the second discharge roller 101c. The film to be coated with glue passes through the first guide roller 102a, and passes between the glue coating roller 101d and the support roller 101e, and then passes through the two lamination rollers 102c. The film to be bonded passes through the second guide roller 102b and enters the interior of the two lamination rollers 102c.

[0063] The two heating rods 206a are operated, and the glue is injected into the interior of the box 101h. The two heating rods 206a heat the glue and transfer the heat to the multiple heat-conducting blocks 206b. The multiple heat-conducting blocks 206b transfer the heat to the horizontal plate 201d, the first filter 201c and the collection box 201a.

[0064] Run the liquid pump 101f-2 to extract the glue inside the box 101h through the glue extraction pipe 101f-1, and then inject it into the glue outlet pipe 101f-4 through the connecting pipe 101f-3. The glue outlet pipe 101f-4 will inject the glue into the surface of the glue coating roller 101d. As the film that needs to be coated with glue passes by, the glue coating roller 101d will coat the film that needs to be coated with glue. After coating, the film is transported to the right. As the two films are transported to the right at the same time, the two pressing rollers 102c will press the two films together, and finally they are collected by the winding roller 101g.

[0065] The excess glue on the glue coating roller 101d will fall into the interior of the collecting box 201a, and the glued film will be transported to the right and the excess glue will be scraped off by the scraping block 205a. As the glue coating roller 101d rotates, the second movable block 205h will drive the movable belt 205g to rotate, and the movable belt 205g will rotate the first movable block 205f. The first movable block 205f will cause the rotating roller 205e to drive the matching block 205j and the pushing plate 205m to rotate. As the pushing plate 205m rotates to the right, under the elastic action of multiple elastic springs 205k, the bottom of the pushing plate 205m will fit with the top of the scraping block 205a, pushing the glue to the right, and entering the interior of the vertical pipe 205d from the two liquid outlets 205b through the guide block, and then entering the interior of the collecting box 201a.

[0066] The rotation of the glue coating roller 101d will cause the second transmission block 202h to rotate, the second transmission block 202h will cause the transmission belt 202g to rotate the first transmission block 202f, the first transmission block 202f will cause the second gear block 202c to drive the gear belt 202e to rotate, and the gear belt 202e will cause the first gear block 202b and the third gear block 202d to rotate, thereby causing multiple stirring rollers 202a to stir the glue inside the box 101h.

[0067] The rotation of the first gear block 202b will cause the first rotating block 203a to rotate and the rotating belt 203b to rotate. The rotating belt 203b will cause the second rotating block 203c to drive the rotating rod 203d and the first bevel gear 203e to rotate. The first bevel gear 203e will cause the double reverse threaded rod 203h to rotate. The double reverse threaded rod 203h will cause the moving block 203j to drive the push rod 203k and the moving part 203m to move left and right repeatedly. The glue entering the collection box 201a will be located inside the moving part 203m and on the top of the first filter screen 201c. The condensed glue will move left and right repeatedly. Under the heat transfer action of multiple heat conducting blocks 206b, the horizontal plate 201d drives the first filter screen 201c to heat the glue, so that the glue passes through the first filter screen 201c and enters the interior of the box body 101h through the discharge port 201e.

[0068] The excess glue on the front and back sides of the two pressed films will be scraped off by the scraper 204g and fall into the interior of the collecting bucket 204c. By running the motor 204e and the two heating plates 204f, the output end of the motor 204e drives the two heating plates 204f to rotate, and the two heating plates 204f heat the glue, so that the melted glue passes through the second filter 204d into the receiving port 204b, and returns to the interior of the box 101h from the conveying pipe 204a, thereby recovering the excess glue.

[0069] In summary, when the speed of gluing needs to be increased, the glue needs to flow faster to meet the glue supply demand. By increasing the speed of the stirring component 202, the glue inside the box 101h maintains fluidity and ensures uniform mixing. The stirring component 202 changes with the rotation speed of the glue roller 101d, which can avoid the fluidity of the glue from decreasing. The excess glue on the top of the film after gluing is scraped off by the glue roller 101d and the scraping component 205, as well as the excess glue generated by the laminated film by the second collecting component 204, is scraped off and recovered to the inside of the box 101h and can be used again, saving resources and avoiding temporary glue shortage caused by glue reduction.
