Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a film sticking machine head and a novel double-sided automatic film sticking device thereof. Background Art

[0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, easy processing, and good sound insulation, heat insulation and fire resistance. It is one of the new light panels that are currently being developed. Gypsum board has been widely used in various buildings such as residential, office buildings, shops, hotels and industrial plants. The interior partition walls, wall covering panels (instead of wall plastering layers), ceilings, sound-absorbing panels, ground base panels and various decorative panels, etc. In the process of gypsum board packaging, the two sides of the gypsum board stack are usually wrapped with a film, while the two ends of the gypsum board stack are not processed, which makes the gypsum board easy to be affected by moisture and dust.

[0003] Patent 202110718285.2 A double-sided automatic film-applying device for gypsum boards can be used to apply film to both ends of a gypsum board stack. Currently, the following problems still exist:

[0004] 1. The membrane head cannot be completely attached to the plate stack, resulting in wrinkles, which causes the membrane head to fall off when affected by external factors, thereby weakening the sealing and moisture-proof effect;

[0005] 2. During the side film lamination process, the lamination roller 364 needs to rotate a certain angle before lamination, which results in the film being unable to be smoothed in a part of the area below the side of the plate stack during lamination, resulting in unsatisfactory effects. After the film is lamination, wrinkles and bulges appear, resulting in poor packaging effects.

[0006] 3. Complex structure and low operating efficiency. Utility Model Content

In addition, if the meaning of "and / or" appearing in the full text is to include three parallel schemes, taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0053] like Figures 1 to 12 As shown, a film laminating machine head 1 includes: a film roll fixing component 12, a smoothing device component 13, a brush component 14, a cutting component 15, a position sensor 16 and a frame 11.

[0054] The film roll fixing assembly 12 is arranged on the frame 11 and is used for installing the film roll 7; it includes a film roll fixing shaft 121, both ends of which are arranged on the frame 11 through bearings; the film roll fixing shaft 121 installed on the frame 11 is combined with the bearings to ensure stable supply of the film roll 7 and provide continuous film material for the film laminating process; the guide roller 122 is arranged in front of the film roll 7 and is used for guiding and conveying the film during the film laminating process. When the film roll 7 is unrolled from the fixing assembly, the guide roller 122 can ensure that the film material is unrolled smoothly and without wrinkles along a predetermined path.

[0055] like Figure 2 and 3 As shown, the smoothing device assembly 13 is arranged under the frame 11, and is used to press the film of the film roll 7 onto the material; wherein, the smoothing frame 131 rotates under the action of the first cylinder 1312 to achieve angle adjustment; the telescopic frame 132 is driven by the second cylinder 1321 to extend and retract forward and backward to ensure that the smoothing roller 133 can penetrate into the bottom of the material; the clamp 134 fixes the film head 71 to ensure that the film head 71 can be pressed on the smoothing roller 133.

[0056] The brush assembly 14 is used to sweep the cut end of the film onto the material; the brush assembly 14 cooperates with the cutting assembly 15 to flatten and fix the end of the film on the material, eliminate the looseness of the film head 71, and ensure a tight fit.

[0057] The cutting assembly 15 includes a heating wire, which is fixedly connected to the brush 141. Specifically, the heating wire can be fixed at both ends of the mounting plate 142 and rotate with the brush assembly 14 to cut the film. The heating wire is used for cutting to accurately control the cutting position of the film.

[0058] The frame 11 provides a mounting platform for the film roll fixing assembly 12 , the smoothing device assembly 13 , the brush assembly 14 and the cutting assembly 15 , ensuring that these components can work together.

[0059] The film head 71 refers to the starting part of the film roll 7 during the film laminating process. The clamp 134 in the equipment is responsible for fixing the starting part of the film roll 7 (the film head 71), ensuring that the film material can be accurately and firmly positioned on the material at the initial stage of laminating, avoiding loosening or deviation of the film head 71 during the laminating process, thereby ensuring the initial sealing and aesthetics of the film laminating; through the operation of the smoothing device assembly 13, the film is pulled from the film roll 7 and attached to the surface of the material, especially through the action of the smoothing roller 133, the film head 71 will be further smoothed and pressed against the surface of the material after being fixed, achieving an ideal smoothing effect and eliminating wrinkles or hollows.

[0060] Position sensors 16 are provided on both sides of the frame 11 to detect that the laminating machine head 1 moves upwards beyond the material height, and then the laminating machine stops moving upwards. The height between the laminating machine head 1 and the material is monitored to ensure that the laminating operation is performed at an appropriate height to avoid waste or poor lamination caused by excessive rise.

[0061] like Figure 4 As shown, the smoothing device assembly 13 includes: a smoothing frame 131, a telescopic frame 132, a smoothing roller 133 and a clamping claw 134.

[0062] A rotating shaft 1311 is provided at one end of the smoothing frame 131, and a bearing is provided at the lower part of the frame body 11. The rotating shaft 1311 passes through the bearing, and a first cylinder 1312 is provided between the smoothing frame 131 and the frame body 11. Driven by the first cylinder 1312, the smoothing frame 131 rotates at a certain angle; through the rotation of the angle of the smoothing frame 131, the telescopic frame 132 and the smoothing roller 133 can be driven to move along a specific trajectory, ensuring that the smoothing operation can fully cover the surface to be bonded.

[0063] The smoothing roller 133 is arranged at one end of the telescopic frame 132, and the telescopic frame 132 performs forward and backward telescopic movement on the smoothing frame 131; the smoothing roller 133 directly contacts the surface of the material to be bonded, and the wrinkles on the surface of the material are removed by rolling the smoothing roller 133 to ensure that the film is flat and tightly attached to the surface of the material.

[0064] The clamping jaws 134 are arranged at both ends of the smoothing roller 133, and are used to press the torn film head 71 onto the smoothing roller 133. The clamping jaws 134 are used to fix and control the starting part (film head 71) of the film roll 7, ensuring that the film material can be accurately and stably positioned at the beginning of lamination, and avoiding misalignment or looseness in the early stage of lamination.

[0065] Guide rails 1322 are arranged on both sides between the smoothing frame 131 and the telescopic frame 132 , and a driving device is arranged on the rear side. The driving device drives the telescopic frame 132 to move forward and backward along the guide rails 1322 on the smoothing frame 131 .

[0066] The driving device includes a second cylinder 1321, a connecting rod 1323 and a slider 1324; one end of the connecting rod 1323 is rotatably connected to the telescopic frame 132, and the other end is rotatably connected to the slider 1324; the slider 1324 moves linearly under the drive of the second cylinder 1321, and the movement direction of the slider 1324 is perpendicular to the movement direction of the telescopic frame 132 along the guide track 1322. The telescopic frame 132 is used to carry the smoothing roller 133 and realize the precise advance and retreat of the smoothing roller 133. The two-step extension and retraction of the telescopic frame 132 driven by the second cylinder 1321 completes the film head 71 being attached to the bottom of the material.

[0067] The slider 1324 performs linear motion on the slide rail of the smoothing frame 131. Through the linear motion on the slide rail, the slider 1324 can drive the connected components to move accurately along a predetermined path, thereby enhancing the stability of the movement of the telescopic rod of the second cylinder 1321.

[0068] One end of the clamping jaw 134 is rotatably arranged on the telescopic frame 132, and a first gear 1341 is arranged on the clamping jaw 134. A first rack 1342 is arranged on the telescopic rod of the third cylinder 1343. Driven by the third cylinder 1343, the first rack 1342 drives the first gear 1341 to rotate, thereby driving the clamping jaw 134 to rotate at a certain angle.

[0069] When the third cylinder 1343 extends or retracts, the linear motion of the first rack 1342 is converted into the rotational motion of the first gear 1341, thereby driving the clamping jaw 134 to rotate to a desired angle. Through the cooperation of the first gear 1341 and the first rack 1342, the precise rotation of the clamping jaw 134 is achieved, so that the clamping jaw 134 can clamp the membrane head 71.

[0070] The brush assembly 14 includes a brush 141 , a second gear 144 , a second rack 145 , a mounting plate 142 , a fourth cylinder 146 and a connecting plate 143 .

[0071] The brush 141 is rotatably arranged at the rear part of the smoothing device assembly, and the specific structure is: the brush 141 is fixed on the mounting plate 142, and the mounting plate 142 is rotatably arranged at the rear part of the smoothing device assembly 13 through the connecting plate 143; the connecting plate 143 is fixedly connected with the rotating shaft of the brush 141, and the rotating shaft is coaxial with the rotating shaft of the smoothing roller; the second gear 144 is fixedly connected with the rotating shaft of the brush 141; the second rack 145 is arranged on the telescopic rod of the fourth cylinder 146, and under the drive of the fourth cylinder 146, the second rack 145 drives the second gear 144 to rotate, thereby driving the brush 141 to rotate at a certain angle.

[0072] The brush assembly 14 is used to smooth the film material to ensure the flatness of the final bonding surface; after the film is cut by the cutting assembly 15, it is swept by the brush assembly 14 and is evenly bonded to the material, effectively avoiding the film on the upper part of the material from not fitting tightly and forming wrinkles.

[0073] The cutting assembly 15 includes: a heating wire, which is fixedly connected to the brush 141. When the position sensor 16 detects Fig.12 After the color code on the membrane is shown, Figure 5 The fourth cylinder 146 shown in the figure carries the second rack 145 to retract, thereby driving the second gear 144 to rotate, rotating the brush 141 and the heating wire 90°, as shown in the figure. Figure 5 The heating wire shown cuts the film.

[0074] like Figure 1 As shown, a novel double-sided automatic film laminating device comprises: a film laminating machine head 1, a lifting and rotating mechanism 2, a lifting device 3, a front arrival detection sensor 4 and a rear arrival detection sensor 5.

[0075] The film laminating machine head 1 is the core mechanism of the automatic film laminating device. The lifting assembly 21 drives the film laminating machine head 1 to move upward from bottom to top, and the film laminating machine head 1 sticks the film on the material.

[0076] The lifting and rotating mechanism 2 includes a lifting component 21 and a rotating component 22. The rotating component 22 is arranged on the lifting component 21. The lifting component 21 drives the rotating component 22 to move up and down, and the rotating component 22 drives the film laminating machine head 1 to rotate. Through the coordinated work of the lifting component 21 and the rotating component 22, the film laminating machine head 1 can be moved up and down and rotated 180 degrees, and the front and back sides of the material can be filmed respectively, thereby improving work efficiency and flexibility.

[0077] The lifting device 3 is arranged below the film laminating machine head 1 and is used to press the film head 71 attached to the material, to press the attached film head 71, to ensure that the film material is closely attached and to prevent warping or falling off.

[0078] The front arrival detection sensor 4 is arranged in front of the film laminating machine head 1 and is used for detecting the arrival of the front side of the material, and the film laminating machine head 1 is laminating the film on the front side;

[0079] The rear arrival detection sensor 5 is arranged behind the film laminating machine head 1 and is used for the rear side arrival detection of the material. After the film laminating machine head 1 rotates 180 degrees, the film laminating machine head 1 sticks the film on the rear side.

[0080] The front arrival detection sensor 4 and the rear arrival detection sensor 5 are used to detect whether the material has reached the predetermined position for film pasting, thereby ensuring the accurate start of the film pasting operation and avoiding mis-pasting or missing pasting.

[0081] The conveyor line 6 is arranged below the laminating machine head 1. Figure 1 The conveyor line 6 shown is replaced by a dotted line, which is used to convey the materials to the right place; it is responsible for conveying the materials, and ensures that the gypsum board and other materials can be accurately in place through the front arrival detection sensor 4 and the rear arrival detection sensor 5, providing a stable working object for the film pasting operation.

[0082] The automatic double-sided film laminating machine packages the front and rear ends of the plate stack respectively. The lifting assembly 21 moves the film laminating machine head 1 assembly to the lower end of the plate stack by lifting. The film roll fixing assembly 12 is used to install the film roll, and the film roll 7 is as follows Figure 8 The color-coded adhesive tape film shown in FIG. Figure 4 The clamps 134 on both sides are fixed. Fig.12 The cross-bonding area shown in the figure is adjusted as follows Figure 1 and Figure 2 The position of the film roll 7 on the film roll fixing assembly 12 shown in the figure makes the film roll 7 consistent with the conveying position of the material, thereby ensuring that Fig.12 The longitudinal adhesive areas on both sides of the color-coded tape shown are aligned and fitted to both sides of the material.

[0083] The working process is:

[0084] The material in this embodiment is a stack of gypsum boards 8 or a stack of boards. The material in this context is a general concept of the stack of boards 8 or the stack of boards. Figure 1 As shown in the figure, the front detection sensor 4 is in place, and the stack of plates stops waiting for film lamination. The entire film laminating machine head 1 descends, and the film head 71 is first transported to the bottom of the stack by the clamping claw 134 assembly, and then Figure 4 As shown, the smoothing device assembly 13 starts to work, the extension rod of the second cylinder 1321 extends out, moves through the slider 1324, the connecting rod 1323 pushes out the telescopic frame 132, and the telescopic frame 132 moves forward along the guide track 1322.

[0085] like Figure 4 and Fig. 9 As shown, the second cylinder 1321 moves the smoothing roller 133 forward by a stroke A through the control of a control switch. The control switch is a three-position center-sealed electromagnetic valve and a magnetic switch.

[0086] Then Figure 3 The first cylinder 1312 shown is extended to lift up the front end of the entire smoothing device assembly 13, that is, the telescopic frame 132 is lifted up. At this time, the smoothing roller 133 presses the film tightly against the lower part of the plate stack (another implementation method in this process is that the film laminating machine head rises slightly driven by the lifting assembly, and the smoothing roller 133 on the telescopic frame 132 carries the film head 71 to the bottom of the material); at the same time, the third cylinder 1343 works, and the clamp 134 releases the film head 71.

[0087] then Figure 4 and Fig. 9 The extension rod of the second cylinder 1321 is extended forward again, and the smoothing roller 133 is pushed forward to continue to move forward by the connecting rod 1323. Fig.11 The smoothing roller 133 shown rolls the membrane head 71 forward to below the plate stack, so that the membrane head 71 is completely fitted to the plate stack.

[0088] The telescopic frame 132 is extended in two steps, and the smoothing roller 133 moves forward two strokes, pressing the film head 71 tightly against the bottom of the sheet stack 8, thereby avoiding the situation where a part of the area below the sheet stack 8 cannot be smoothed during film lamination, resulting in an unsatisfactory film lamination effect and wrinkles, bulging, etc. after film lamination is completed.

[0089] Then, the first cylinder 1312 and the second cylinder 1321 are fully retracted, and the entire smoothing device assembly 13 is retracted; Fig.11 As shown, the lifting device 3 is then lifted to press the membrane head 71 tightly onto the plate stack.

[0090] like Fig.11 As shown, the lifting assembly 21 drives the film laminating machine head 1 to rise. At the moment of starting the rise, the telescopic rod of the second cylinder 1321 is extended again to push out the smoothing roller 133. The smoothing roller 133 in the smoothing device assembly 13 is used to smooth the film from the bottom of the plate stack to ensure that the film is flat, and gradually covers the entire end surface from bottom to top.

[0091] The smoothing rollers continuously smooth the bottom and sides of the plate stack, with good smoothing effect and simple structure, making the equipment more stable and reliable during operation, while increasing the film laminating speed and reducing production costs.

[0092] When the sensor detects Fig.12 After the color mark on the film is shown, the fourth cylinder 146 carries the second rack 145 to retract, thereby driving the second gear 144 to rotate, as shown in FIG. Fig.11 As shown, the brush 141 and the heating wire are rotated 90 degrees, the heating wire cuts the film, and the brush 141 sweeps the cut film onto the plate stack.

[0093] When the laminating machine head 1 has finished laminating one end from bottom to top, the stack of sheets is transported forward. Figure 1After the rear-end detection sensor 5 is reached, the plate stack stops moving forward and waits for film lamination. The rotating assembly 22 rotates the film laminating machine head 1 by 180° to package and laminate the plate stack end surface from bottom to top again.

[0094] The “fixed connection” in this embodiment includes direct fixed connection and also includes the situation where the connection is indirectly fixed through other components.

[0095] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
