[0066] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0067] Embodiment 1

[0068] This embodiment provides an automatic film laminating device for label instructions. As Figures 1 to 5 shown, the automatic film laminating device for label instructions includes a frame 1, a controller fixedly arranged on the frame 1, a loading rack 2 fixedly arranged on the frame 1, a film laminating device 3 fixedly arranged at one end position of the frame 1 corresponding to the loading rack 2, a bottom film unwinding roller 4 rotatably installed at one end position of the frame 1 corresponding to the loading rack 2 away from the film laminating device 3, a top film unwinding roller 5 rotatably installed at a position above the film laminating device 3 on the frame 1, a release film winding roller 6 rotatably installed at a position on one side of the top film unwinding roller 5 on the frame 1, a finished product winding roller 7 rotatably installed at a position below the film laminating device 3 on the side of the frame 1 away from the bottom film unwinding roller 4, and a first driving mechanism 8 arranged on the frame 1 and connected to the output end of the controller for driving the release film winding roller 6 and the finished product winding roller 7 to rotate; a first guide roller 21 for winding the bottom film on the bottom film unwinding roller 4 onto the surface of the loading rack 2 is rotatably installed at one end of the loading rack 2 away from the film laminating device 3, and a positioning rack 22 for placing label instructions for loading is arranged on the loading rack 2.

[0069] In order to adapt to the positioning of label instructions of different specifications, the positioning rack 22 includes support bars 221 symmetrically arranged at a position above the loading rack 2 and a second driving mechanism 222 fixedly arranged at the bottom of the loading rack 2 for driving the two support bars 221 to move longitudinally synchronously above the loading rack 2. At least two limiting rods 223 are installed on the inner sides of the two support bars 221. The limiting rods 223 are slidably connected to the support bars 221, and the adjacent two limiting rods 223 and the two support bars 221 form a positioning groove for placing label instructions.

[0070] It should be noted that the second driving mechanism 222 includes four driving parts (the driving part is a linear driving mechanism, which can be an electric push rod, a cylinder, etc.). The four driving parts are symmetrically installed in pairs at the bottom of the loading rack 2. The movable ends of the two driving parts in the same group longitudinally penetrate through the loading rack and are respectively fixedly connected to both ends of one of the support bars 221.

[0071] Before use, move the limiting rod 223 according to the width of the label instruction manual so that the distance between two adjacent limiting rods 223 corresponds to the width of the label instruction manual; set the bottom film roll set for placing the label instruction manual on the bottom film unwinding roller 4, and pass one end of the bottom film around the first guiding roller 2, and make the bottom film pass through the feeding rack 2 and the film laminating device 3 and be fixed to the finished product winding roller 7; at the same time, set the facial mask roll set on the facial mask unwinding roller 5, fix one end of the release film of the facial mask to the release film winding roller 6, and make the facial mask pass through the film laminating device and then be fixed to the finished product winding roller 7. Adjust the distance between two adjacent limiting rods 223 according to the width of the label instruction manual to position the label instruction manual and avoid the offset of the label instruction manual placement.

[0072] During use, drive the finished product winding roller 5 to rotate through the first driving mechanism 8. While winding the finished product, pull the bottom film and the facial mask to move through the film laminating device 3. When the corresponding position on the bottom film reaches below the positioning frame 22, place the label instruction manual in the positioning groove, and make the support bar 221 move away from the feeding rack 2 through the second driving mechanism 222. Then, driven by the finished product winding roller 5, the bottom film with the label instruction manual and the facial mask on the facial mask unwinding roller 6 pass through the film laminating device 3 to complete the film laminating work on the label instruction manual, and the release film of the facial mask is wound and collected by driving the release film winding roller 7 through the first driving mechanism 8.

[0073] To improve the stability of the bottom film feeding, further, a deviation rectifying mechanism 23 connected to the controller in a two-way manner is fixedly installed at one end of the feeding rack 2 away from the film laminating device 3. At least one second guiding roller 24 for winding the bottom film around the deviation rectifying roller 231 of the deviation rectifying mechanism 23 is rotatably installed on the feeding rack 2, and at least one third guiding roller 25 for winding the bottom film around the first guiding roller 21 is rotatably installed on the feeding rack 2; during use, the bottom film is wound from the bottom film unwinding roller 4 around the deviation rectifying roller 231 of the deviation rectifying mechanism 23 through the second guiding roller 24 and then extends to the surface of the feeding rack 2 through the action of the third guiding roller 25 and the first guiding roller 21. When the bottom film is offset, the bottom film is rectified under the action of the deviation rectifying mechanism 23, so as to avoid the offset of the bottom film and ensure the stability of the bottom film feeding.

[0074] It should be noted that the deviation rectifying mechanism 23 uses a sensor to detect the edge of the bottom film. When the sensor does not detect the edge of the bottom film, the deviation rectifying roller 231 floats to rectify the bottom film. It is from Dongguan Boxin Intelligent Control Technology Co., Ltd. and is prior art.

[0075] In order to achieve automated production, furthermore, the automatic film laminating device further includes a detection mechanism 26 fixedly arranged on the loading rack 2 corresponding to the positioning rack 22 and the deviation rectifying mechanism 23 for detecting the position of the printed matter on the base film; the detection mechanism 26 detects the position of the printed matter on the base film and transmits the detected position information to the controller, and the controller controls the rotation speed of the first driving mechanism 8 according to the detected position of the printed matter and the set product length, so as to realize the rotation speed control of the finished product winding roller 7 and the release paper winding roller 6, and achieve automated production.

[0076] Among them, in order to detect the position of the printed matter on the base film, the detection mechanism 26 includes an electric eye 261 connected to the input end of the controller, a sliding frame 262 symmetrically arranged on the loading rack 2, a first slider 263 moving horizontally on the sliding frame 262, two slide rods 264 fixedly arranged at both ends on the two first sliders 263 respectively, and a second slider 265 moving horizontally on the two slide rods 264, and the electric eye 261 is fixedly installed on the second slider 265. It can be understood that during the initial use, the position of the electric eye 261 can be adjusted according to the position of the electric eye 261, so as to meet the detection requirements of the printing position of the printed matter on the base film.

[0077] In order to wind the finished product and the release film of the facial mask and realize the automatic film laminating work of the label instruction manual; specifically, the first driving mechanism 8 includes a driving sprocket 81 rotatably installed inside the machine frame 1, two driven sprockets 82 respectively fixedly sleeved on the release film winding roller 6 and the finished product winding roller 7, a chain 83 for drivingly connecting the two driven sprockets 82 with the driving sprocket 81 respectively, and a second servo motor 84 fixedly installed inside the machine frame 1 and connected to the output end of the controller for driving the driving sprocket 81 to rotate. During film lamination, the controller controls the second servo motor 84 to rotate, thereby driving the driving sprocket 81 to rotate, synchronously driving the two driven sprockets 82 to rotate through the two chains 83, thereby driving the release film winding roller 6 and the finished product winding roller 7 to rotate, respectively winding the release film and the finished product. The finished product winding roller 7 pulls the finished product to unwind the base film and the facial mask, so as to realize the automatic film laminating of the label instruction manual.

[0078] Embodiment 2

[0079] This embodiment provides an automatic film laminating device for label instruction manuals, as Figures 1 to 6As shown in the figure, different from Embodiment 1, the film laminating device 3 includes a support frame 31 fixedly arranged at one end of the loading rack 2, a drag roller 32 rotatably arranged on the support frame 31 for contacting the bottom film, a pressing roller 33 rotatably installed on the support frame 31 for laminating the facial mask, an adjusting mechanism 34 arranged on the support frame 31 to make the pressing roller 33 contact the facial mask, and a first servo motor 35 fixedly arranged on the frame 1 and connected to the output end of the controller for driving the drag roller 32 to rotate. Among them, in order to enable the facial mask to pass through the gap between the pressing roller 33 and the drag roller 32, and make the finished product after being compounded by the pressing roller 33 and the drag roller 32 wind around the finished product winding roller 7; the film laminating device 3 further includes a fourth guide roller 36 rotatably installed on the support frame 31 for winding the facial mask between the pressing roller 33 and the drag roller 32, and a fifth guide roller 37 rotatably installed on the support frame 31 for winding the finished product around the finished product winding roller 7.

[0080] The bottom film with the label instruction is connected to the finished product winding roller 7 through the drag roller 32, and the facial mask contacts the upper surface of the bottom film through the gap between the pressing roller 33 and the drag roller 32, and moves under the winding drive of the finished product winding roller 7; the pressing roller 33 presses the facial mask on the upper surface of the bottom film under the action of the adjusting mechanism 34, and the first servo motor 35 drives the pressing roller 33 to rotate, so that the facial mask is compounded with the upper surface of the bottom film, and the compounding work of the label instruction is completed.

[0081] It can be understood that the gap between the pressing roller 33 and the drag roller 33 can be effectively controlled through the adjusting mechanism 34, and it can adapt to the film laminating work of label instructions of different specifications. During use, the bottom surface of the bottom film contacts the outer wall of the drag roller 32, the outer surface of the facial mask contacts the outer wall of the pressing roller 33, and its bonding surface contacts the upper surface of the bottom film and the outer surface of the label instruction, and the facial mask is compounded with the bottom film under the extrusion force of the pressing roller 33 and the drag roller 32.

[0082] In order to adjust the gap between the pressing roller 33 and the drag roller 32; specifically, guide grooves 311 are symmetrically formed on the support frame 31, and the adjusting mechanism 34 includes a first support block 341 and a second support block 342 slidably installed in the guide grooves 311, two springs 343 respectively fixedly arranged between the first support block 341 and the guide grooves 311 and between the second support block 342 and the first support block 341, a pressing roller 344 rotatably installed at both ends on the second support block 342 for contacting the outer wall of the pressing roller 33, and an adjusting rod 345 screwed on the support frame 31 and rotatably connected to the second support block 342. Both ends of the pressing roller 33 are rotatably installed on the two first support blocks 341.

[0083] When adjusting the gap between the laminating roller 33 and the material dragging roller 32, rotate the adjusting rod 345 to push the second slider 342 to move closer to the first slider 341. At this time, the outer wall of the pressure roller 344 contacts the outer wall of the laminating roller 33, forcing the laminating roller 33 to move closer to the material dragging roller 32, thereby reducing the gap between the laminating roller 33 and the material dragging roller 32. Rotate the adjusting rod 345 to make the second slider 342 move away from the first slider 341 under the elastic force of the spring 343, and then make the pressure roller 344 disengage from the laminating roller 33. Also under the elastic force of the spring 343 between the first slider 341 and the guiding groove 311, the first slider 341 is forced to move, driving the laminating roller 33 to move away from the material dragging roller 32, thereby increasing the gap between the laminating roller 33 and the material dragging roller 32. Among them, the outer walls of the laminating roller 33 and the pressure roller 344 are always in contact under the elastic forces of the two springs 33.

[0084] Embodiment 3

[0085] This embodiment provides an automatic film laminating device for label instructions, as Figure 5 and Figure 6 shown. Different from Embodiment 2, a driving gear 321 is fixedly installed at one end of the material dragging roller 32, and a driven gear 331 for meshing with the driving gear 321 is fixedly installed on the laminating roller 33.

[0086] It can be understood that when the gap between the laminating roller 33 and the material dragging roller 32 is the minimum gap of this film laminating device (i.e., the minimum thickness that can use the film), the driven gear 331 meshes with the driving gear 321. At this time, the first servo motor 35 drives the material dragging roller 32 to rotate. Under the cooperation of the driving gear 321 and the driven gear 331, the laminating roller 33 rotates to laminate the facial mask on the upper surface of the base film.

[0087] It should be noted that when adjusting the gap between the laminating roller 33 and the material dragging roller 32, the driving gear 321 and the driven gear 331 can be rotated respectively by rotating the material dragging roller 32 and the laminating roller 32, so that when the gap between the laminating roller 33 and the material dragging roller 32 is the minimum gap, the driven gear 331 can mesh with the driving gear 321.

[0088] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent replacements or changes, and should be covered within the protection scope of the present application.
