[0015] As a preferred technical solution of the present invention, a method for using a full-width inner lamination without floating tail automatic film loading device, using a full-width inner lamination without floating tail automatic film loading device, comprises the following steps:

[0016] Step 1: When in use, the product to be treated with film is placed inside the placement frame. At the same time, the film to be used passes through the smoothing roller, and then is input into the inner side of the protection frame through the set tensioning roller. At this time, the film passes through the set cleaning roller and the feeding roller and is output through the notch opened on one side of the top of the protection frame. The output film extends into the protection frame set on the inner side of the other end of the support frame and repeats the previous steps.

[0017] Step 2: After the film processing is completed, the first motor works to make the transmission roller work to realize the lateral conveyance of the conveyor belt, and the placement frame is conveyed to the middle and lower part of the processing box. At this time, the hydraulic cylinder works to push the adjustment seat longitudinally to realize the longitudinal movement of the processing box, and then the longitudinal movement of the processing box is used to realize the synchronous movement of the flexible pressure head, so that the film is attached to the surface of the product by using the longitudinal movement of the flexible pressure head;

[0018] Step three: During the downward pressing process of the flexible pressure head, the hot air blower draws outside air into the inner side of the ventilation cavity, and filters and purifies the air through the guide seat and the honeycomb filter plate arranged on the inner side of the ventilation cavity, and then utilizes the hot air blower to perform heat treatment on the treated air, and outputs the heat-treated air through the second air hole, so as to facilitate the film to better fit the surface of the product when the flexible pressure head works later.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The hot air blower, the first damper, the first spring and the flexible pressure head and other structures are combined to facilitate the subsequent film application process on the product, so that the film can better fit the surface of the product, thereby preventing the film on the surface of the product from having wrinkles after the film application is completed, which affects the aesthetics of the product. The overall practicality of the structure is higher and the film application effect is better. The hot air blower can process the air, and then the heat-treated air is discharged through the pores opened at the bottom of the flexible pressure head, thereby heat-treating the film. Then, under the downward pressure of the flexible pressure head, the film can be better fitted to the film of the product, and the heat-treated film can be more closely fitted to the surface of the product, thereby preventing the generation of wrinkles, and the reverse force generated by the deformation of the damper and the first spring can enable the flexible pressure head to better press down the film;

[0021] 2. Combined with the second damper and the hot pressing roller and other structures, it is convenient to press the edge of the film and the product in the subsequent process, so as to prevent the film and the edge of the product from not being effectively bonded after the film is applied, which results in the need for secondary processing in the subsequent process. When the entire processing box moves longitudinally, it will drive the hot pressing roller to move synchronously, and when the hot pressing roller moves longitudinally, it will move along the edge of the product, so that the work of the hot pressing roller can be used to press the film at the edge of the product, so that it can better fit the edge of the product.

[0022] 3. Combined with the tensioning roller, feeding roller and sweeping roller and other structures, the film to be coated can be effectively tensioned, thereby preventing wrinkles from forming during transportation and affecting subsequent coating. At the same time, when the film passes through the sweeping roller, the rotating sweeping roller can be used to perform simple dust removal on the side of the film that is in contact with the product surface, thereby preventing the surface of the film from being adsorbed with a lot of dust, which would affect the subsequent film bonding effect. The overall practicality is higher, and the longitudinal movement of the tensioning roller can adjust the tensioning of the film, and then the lateral transportation of the film can be achieved in conjunction with the movement of the feeding roller, which is convenient for subsequent coating.

The flexible pressing head 21 is slidably connected to the processing box 10 through the first damper 19, and the first damper 19 is symmetrically distributed along the vertical center line of the flexible pressing head 21. The bottom of the air flow groove 22 is connected with the second air hole 23, and the second air hole 23 is equidistantly distributed at the bottom of the flexible pressing head 21, and the second air hole 23 is connected with the air flow groove 22. The second damper 24 is fixedly installed on the periphery of the bottom of the processing box 10, and one end of the second damper 24 is connected to the hot pressing roller 25;

[0036] When it is necessary to automatically apply film to the product, first place the product to be applied to the film on the inner side of the placement frame 5, then the first motor 2 works to rotate the transmission roller 3 connected to its output end, and the rotation of the transmission roller 3 is used to realize the lateral transportation of the conveyor belt 4, and then the lateral movement of the conveyor belt 4 is used to transport the placement frame 5 to the bottom of the processing box 10. At this time, the hydraulic cylinder 8 works to longitudinally push the adjustment seat 9 fixedly connected to its bottom, and the longitudinal movement of the adjustment seat 9 is used to realize the longitudinal movement of the processing box 10, which is convenient for the subsequent film application of the product. During the film application, the hot air blower 18 works to draw the outside air into the inner side of the ventilation cavity 11 through the air inlet groove 12, and then the air passes through the guide groove 15 opened on the upper surface of the guide seat 14, and the guide groove 15 is used for simple diversion treatment, and the air can be simply filtered in conjunction with the multiple arc grooves 16 evenly distributed at the bottom of the guide groove 15. Then the air after the diversion treatment passes through the set honeycomb filter plate 17, and the set honeycomb filter plate 17 is used The air is filtered and impurity-removed. The treated air is heat-treated under the action of the hot air blower 18 and then discharged through the air outlet 13. The discharged hot air will be input into the inner side of the air flow groove 22, so as to be discharged through the second air hole 23 later. At this time, the longitudinal movement of the processing box 10 drives the flexible pressure head 21 to press the film longitudinally downward, so that the film fits the surface of the product. Under the action of the hot air, the heat-treated film can better fit the film of the product. At the same time, when the flexible pressure head 21 presses the film longitudinally downward to make it contact with the surface of the product, the first damper 19 will drive the first spring 20 to deform and generate a reverse force. The reverse force generated by the deformation of the two can make the flexible pressure head 21 better drive the film to contact the surface of the product. At the same time, the hot pressing roller 25 will contact the edge of the product, and then the film at the edge of the product can be pressed, so that it can better fit the edge surface of the product, improve the film-applying effect, and the overall practicality is higher.

[0037] As a further implementation of this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a smoothing roller 26 is rotatably connected to the inner side wall of one end of the support frame 1, and a fixing frame 27 is distributed on one side of the top of the smoothing roller 26, a third damper 28 is fixedly installed on the inner side of the fixing frame 27, and a second spring 29 is sleeved on the outer surface of the third damper 28, a tensioning roller 30 is connected to the top of the third damper 28, a protective frame 31 is distributed on the side of the tensioning roller 30 away from the smoothing roller 26, and a feeding roller 32 is provided in the inner cavity of the protective frame 31, and a cleaning roller 33 is distributed below the feeding roller 32;

[0038] When in use, the film is first passed through the two smoothing rollers 26. Since the smoothing rollers 26 are rotatably connected to the support frame 1 and the two symmetrically distributed smoothing rollers 26 move toward each other, the smoothing rollers 26 can be used to simply smooth the film. After passing through the smoothing rollers 26, the film will pass through the tensioning rollers 30. When the tensioning rollers 30 move longitudinally, they will squeeze the third damper 28 fixedly connected to its bottom and cause it to deform accordingly. At the same time, when the third damper 28 is deformed, the second spring 29 will be deformed synchronously, and then the two shapes will be combined to form a film. The reverse force generated by the change can make the tensioning roller 30 effectively tension the film to prevent the film from being wrinkled during the subsequent transportation process. After passing through the tensioning roller 30, the film will be input into the inner side of the protection frame 31, and pass through the provided cleaning roller 33. The surface of the film is simply dusted by the rotation connection between the cleaning roller 33 and the protection frame 31. After the dust is removed, the film will pass through the provided feeding roller 32, and another independently working first motor 2 will be used to realize the rotation of the feeding roller 32, thereby realizing the lateral transportation of the film.

[0039] As a further implementation of this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, an outer shell 34 is distributed on one side of the top of the first motor 2, and a second motor 35 is fixedly installed on one end surface of the outer shell 34, a rotating rod 36 is connected to the output end of the second motor 35, and an adjusting roller 37 is connected to the inner side of one end of the rotating rod 36, the rotating rod 36 is rotatably connected to the support frame 1, and the adjusting roller 37 is rotatably connected to the rotating rod 36;

[0040] When the film passes through the protective frame 31 provided on one side of the support frame 1 and extends to the inner side of another independent protective frame 31 provided on the inner side of the other end thereof, the film will pass through the adjusting roller 37. When the film needs to be pressed onto the surface of the product, the second motor 35 works to rotate the rotating rod 36 connected to its output end, and then the rotation of the rotating rod 36 is used to realize the rotation of the adjusting roller 37, so that the film is pressed down by the rotating adjusting roller 37. The synchronous movement of the adjusting rollers 37 on both sides can press the film down to a suitable position height, making it parallel to the product, so as to facilitate the subsequent use of the flexible pressing head 21 for better film application on the product.

[0041] Specific working principle:

[0042] First, the film is passed through two smoothing rollers 26. Since the smoothing roller 26 is rotatably connected to the support frame 1 and the two symmetrically distributed smoothing rollers 26 move toward each other, the smoothing rollers 26 can be used to simply smooth the film. After passing through the smoothing rollers 26, the film will pass through the tensioning roller 30. When the tensioning roller 30 moves longitudinally, it will squeeze the third damper 28 fixedly connected to its bottom and cause it to deform accordingly. At the same time, when the third damper 28 is deformed, the second spring 29 will be deformed synchronously. Combined with the reverse force generated by the deformation of the two, the tensioning roller 30 can effectively tension the film to prevent the film from being wrinkled during the subsequent transportation process. After passing through the tensioning roller 30, the film will be transported The film is passed through the inner side of the protective frame 31 and passes through the cleaning roller 33. The surface of the film is simply dusted by the rotation connection between the cleaning roller 33 and the protective frame 31. After the dust removal, the film passes through the feeding roller 32. Another independently working first motor 2 is used to realize the rotation of the feeding roller 32, thereby realizing the lateral conveying of the film. Then, the product to be processed by the film is placed on the inner side of the placement frame 5. Then, the first motor 2 works to rotate the transmission roller 3 connected to its output end. The rotation of the transmission roller 3 is used to realize the lateral conveying of the conveyor belt 4. Then, the lateral movement of the conveyor belt 4 is used to transport the placement frame 5 to the bottom of the processing box 10. At this time, the hydraulic cylinder 8 works to longitudinally push the adjustment fixed connection at its bottom The seat 9 is used to adjust the longitudinal movement of the processing box 10, so as to facilitate the subsequent film application on the product. When the film passes through the protective frame 31 set on one side of the support frame 1 and extends to the inner side of another independent protective frame 31 set on the inner side of the other end thereof, the film will pass through the adjusting roller 37. When the film needs to be pressed onto the surface of the product, the second motor 35 works to rotate the rotating rod 36 connected to its output end, and then the rotation of the rotating rod 36 is used to realize the rotation of the adjusting roller 37, so as to use the rotating adjusting roller 37 to press the film downward. Then, the synchronous movement of the adjusting rollers 37 on both sides can press the film down to a suitable position height, making it parallel to the product, so as to facilitate the subsequent use of the flexible pressing head 21 for better film treatment of the product, at this time, the hot air blower 18 works to draw the outside air into the inner side of the ventilation cavity 11 through the air inlet groove 12, and then the air passes through the guide groove 15 opened on the upper surface of the guide seat 14, and uses the guide groove 15 for simple diversion treatment, and cooperates with a plurality of arc grooves 16 evenly distributed at the bottom of the guide groove 15 to perform simple filtering treatment on the air, and then the diversion treated air passes through the set honeycomb filter plate 17, and uses the set honeycomb filter plate 17 to filter and remove impurities from the air, the treated air is heat treated under the action of the hot air blower 18, and then discharged through the air outlet 13, and the discharged hot air will be input into the inner side of the air flow groove 22, so as to be discharged through the second air hole 23 later.At this time, the longitudinal movement of the processing box 10 drives the flexible pressure head 21 to press the film longitudinally, so that the film fits the surface of the product, and under the action of the hot air, the heat-treated film can better fit the film of the product. At the same time, when the flexible pressure head 21 presses the film longitudinally to make it contact with the surface of the product, the first damper 19 will drive the first spring 20 to deform and generate a reverse force. The reverse force generated by the deformation of the two can make the flexible pressure head 21 better drive the film to contact the surface of the product. At the same time, the hot pressing roller 25 will contact the edge of the product, and then the film at the edge of the product can be pressed, so that it can better fit the edge surface of the product, improve the film-applying effect, and have higher overall practicality.

8. A method for using a full-width inner laminating without floating tail automatic film loading device, comprising the full-width inner laminating without floating tail automatic film loading device according to any one of claims 1 to 7, characterized in that: The following steps are involved: Step 1: When in use, the product to be treated with film is placed on the inner side of the placement frame (5). At the same time, the film to be used passes through the smoothing roller (26) and then passes through the set tensioning roller (30) to be input into the inner side of the protection frame (31). At this time, the film passes through the set cleaning roller (33) and feeding roller (32) and is output through the slot opened on one side of the top of the protection frame (31). The output film extends into the protection frame (31) set on the inner side of the other end of the support frame (1) and repeats the previous steps. Step 2: After the film processing is completed, the first motor (2) operates to make the driving roller (3) operate to realize the lateral conveyance of the conveyor belt (4), and the placement frame (5) is conveyed to the middle and lower part of the processing box (10). At this time, the hydraulic cylinder (8) works to push the adjustment seat (9) longitudinally to realize the longitudinal movement of the processing box (10), and then the longitudinal movement of the processing box (10) is used to realize the synchronous movement of the flexible pressure head (21), so as to make the film fit the surface of the product by using the longitudinal movement of the flexible pressure head (21); Step 3: During the downward pressing process of the flexible pressure head (21), the hot air blower (18) operates to draw outside air into the inner side of the ventilation cavity (11), and filters and purifies the air through the guide seat (14) and the honeycomb filter plate (17) arranged on the inner side of the ventilation cavity (11). The hot air blower (18) is then used to heat treat the treated air, and the heat-treated air is output through the second air hole (23), so that the film can better fit the surface of the product when the flexible pressure head (21) works later.
