Description

Technical Field

[0001] The invention relates to the technical field of glass processing equipment, and in particular to a film laying machine for producing laminated glass. Background Art

[0002] Laminated glass, as a high-performance composite glass product, is usually composed of two or more pieces of glass and one or more layers of organic polymer interlayers sandwiched between them. These interlayer materials, such as PVB, SGP, EVA, PU, ​​etc., are permanently bonded to the glass layer through special high-temperature pre-pressing or vacuum treatment, and subsequent high-temperature and high-pressure processes to form a strong and impact-resistant composite structure. This structure not only improves the strength and safety of the glass, but also enhances its sound insulation, heat insulation and UV resistance.

[0003] In the production process of laminated glass, film laying is a key step. At present, this step mainly relies on manual operation. Specifically, the production process includes conveying a piece of glass to a designated position on the laminated glass production line, and then manually laying a film on the glass and flattening it manually. Next, the film is cut according to the size of the glass, and finally another piece of glass is covered on the film.

[0004] However, this traditional manual operation method has obvious shortcomings. First, the flattening and cutting process of the film is time-consuming and labor-intensive, resulting in low production efficiency. Second, manual operation cannot guarantee the flattening effect of the film, which in turn affects the overall quality and appearance of the laminated glass. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art that it is difficult to ensure the flattening effect of the film by manual operation, and to propose a film laying machine for laminated glass production.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A film laying machine for laminated glass production is designed, comprising a machine platform with a supporting frame installed on the side, the supporting frame is used to carry a film roller;

[0008] and a film-drawing mechanism, a cutting mechanism, a conveying mechanism and a flattening mechanism installed on the machine platform;

[0009] The paving mechanism comprises a lifting frame, a driving member for driving the lifting frame to move up and down is fixedly mounted on the machine platform, and a pressing roller and a paving roller are also arranged at the bottom of the lifting frame.

[0010] Furthermore, the clamping roller member includes two telescopic rods fixedly mounted on the inner side of the lifting frame, a spring is fixedly connected between the pipe sections of the two telescopic rods, and a clamping roller is rotatably connected between the tail ends of the two telescopic rods.

[0011] Furthermore, the flattening roller comprises a rotating shaft rotatably connected to the inner side of the lifting frame, and two swing arms are fixed at intervals on the outer side of the rotating shaft through two connecting frames, wherein a flattening roller is rotatably connected between the bottoms of the two swing arms.

[0012] Furthermore, a connecting column is fixed on the inner side of the lifting frame, and a tension spring is arranged between the connecting column and the connecting frame.

[0013] Furthermore, it also includes a limiting assembly arranged between the rotating shaft and the lifting frame, and the limiting assembly is used to lock the circumferential position of the rotating shaft.

[0014] Furthermore, the limiting assembly includes a ratchet fixed on the outside of the rotating shaft, a rod movably inserted on the lifting frame, a clamping block fixedly installed on the end of the rod and engaged with the teeth of the ratchet, wherein a reset spring is arranged between the rod and the lifting frame.

[0015] Furthermore, a U-shaped frame is fixed on the inner side of the lifting frame, two ends of the return spring respectively abut against the U-shaped frame and the lifting frame, and the insertion rod is plugged into the U-shaped frame.

[0016] Furthermore, the end of the insertion rod passes through the lifting frame and is fixed with a frustum, and an unlocking ring is fixedly installed on the top of the machine, and the unlocking ring contacts the inclined surface of the frustum.

The system can automatically complete the pulling, cutting and flattening operations of the film, greatly improving the operating efficiency, and has significant advantages over the traditional manual operation method. Secondly, in the design of the flattening mechanism, two key components, the clamping roller and the flattening roller, are used. The clamping roller is responsible for clamping one side of the film, while the flattening roller ensures that the film can be laid flatly on the upper surface of the glass by moving laterally. This design not only improves the film laying efficiency, but also ensures the flatness of the film laying. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-4 As an embodiment of the invention, a film laying machine for producing laminated glass is disclosed. Specifically, the film laying machine comprises a machine table 1 with a supporting frame 11 installed on the side. The supporting frame 11 is used to carry a film roller. In addition, the film roller is rotatably connected to the inner side of the supporting frame 11 for easy unwinding.

[0027] and a film-drawing mechanism 2, a cutting mechanism 3, a conveying mechanism 4 and a flattening mechanism 5 installed on the machine table 1. Specifically, the conveying mechanism 4 described in this embodiment includes a plurality of conveying rollers for conveying glass, and the cutting mechanism 3 includes a cutting frame, on which a cutter is driven to extend and retract by a cylinder to cut the film;

[0028] Among them, the paving mechanism 5 includes a lifting frame 51, and a driving member 52 for driving the lifting frame 51 to move up and down is fixedly installed on the machine 1. Preferably, the driving member 52 in this embodiment is a cylinder, and two cylinders are arranged at intervals. A clamping roller 6 and a paving roller 7 are also arranged at the bottom of the lifting frame 51.

[0029] In some embodiments, the clamping roller 6 in the present invention includes two telescopic rods 61 fixedly installed on the inner side of the lifting frame 51, a spring 62 is fixedly connected between the pipe sections of the two telescopic rods 61, and a clamping roller 63 is rotatably connected between the tail ends of the two telescopic rods 61.

[0030] On the basis of the above-mentioned embodiments, the flattening roller 7 in the present invention includes a rotating shaft 71 rotatably connected to the inner side of the lifting frame 51, and two swing arms 73 are fixed at intervals on the outer side of the rotating shaft 71 through two connecting frames 72, wherein a flattening roller 74 is rotatably connected between the bottoms of the two swing arms 73. Further, the connecting frame 72 described in this embodiment includes two sleeves, and the two sleeves are respectively sleeved and fixed on the swing arm 73 and the rotating shaft 71, and the two sleeves are fixed by a rod to keep the swing arm 73 able to rotate with the rotating shaft 71. It should be noted that in the initial state, the swing arm 73 in the present invention is tilted to facilitate the subsequent guidance of its rotation.

[0031] Of course, in consideration of the resetting of the swing arm 73 after the rotation, in this embodiment, a connecting column 75 is further fixed on the inner side of the lifting frame 51 , and a tension spring 76 is provided between the connecting column 75 and the connecting frame 72 .

[0032] That is to say, during operation, the glass enters along the conveying mechanism 4, and the film pulling mechanism 2 pulls out the rolled film on the film roller, and the user manually spreads the film on the glass surface, and then the driving member 52 drives the lifting frame 51 to move downward, and the pressing roller member 6 first presses one side of the film to prevent it from moving when it is subsequently spread out;

[0033] When the lifting frame 51 moves further downward, the telescopic rod 61 continues to shrink, and the clamping roller 63 always contacts the upper surface of the film. Then, the flattening roller 74 contacts the film. With the help of the rotatable ability of the rotating shaft 71, when the lifting frame 51 continues to rotate, the entire swing arm 73 starts to rotate, and at the same time drives the flattening roller 74 to push the film on the glass surface to flatten it. Since the other side of the film is pressed by the clamping roller 63 and cannot move, when the swing arm 73 rotates, it can drive the flattening roller 74 to smoothly flatten the film on the glass surface. Thereafter, the film can be cut by the cutting mechanism 3. After the mechanisms are reset, the glass with the film can be removed for subsequent lamination to form laminated glass.

[0034] Taking into account that the swing arm 73 will drive the flattening roller 74 to move back when in service, in order to avoid affecting the flattened film, the present invention also includes a limit assembly 8 arranged between the rotating shaft 71 and the lifting frame 51, and the limit assembly 8 is used to lock the circumferential position of the rotating shaft 71. That is to say, the design of the limit assembly 8 is adopted in the present invention to keep the swing arm 73 in unidirectional rotation so that reversal will not occur during the subsequent resetting process, thereby avoiding the flattening roller 74 from affecting the film.

[0035] In a preferred embodiment, the limiting assembly 8 in the present invention includes a ratchet 81 fixed to the outside of the rotating shaft 71, and a plug rod 82 is movably inserted on the lifting frame 51, and a clamping block 83 that is fixedly installed on the end of the plug rod 82 and is clamped with the teeth of the ratchet 81. Of course, the end of the clamping block 83 can be set to a wedge-shaped structure, wherein a reset spring 84 is set between the plug rod 82 and the lifting frame 51.

[0036] That is, in the present invention, the ratchet 81 and the clamping block 83 are used to achieve the unidirectional rotation requirement of the rotating shaft 71. Specifically, when the lifting frame 51 descends, the swing arm 73 can rotate smoothly until the leveling action is completed, and the ratchet 81 and the clamping block 83 lock the current position of the swing arm 73. Thereafter, when the lifting frame 51 moves upward and resets, the swing arm 73 and the leveling roller 74 always maintain the final position and move upward, so as not to interfere with the film, thereby further optimizing the stability of the film laying.

[0037] In order to improve the movement stability of the insertion rod 82, in this embodiment, a U-shaped frame 85 is fixed on the inner side of the lifting frame 51, and the two ends of the return spring 84 respectively abut against the U-shaped frame 85 and the lifting frame 51, and the insertion rod 82 is plugged into the U-shaped frame 85.

[0038] Of course, in order to unlock the ratchet 81 to achieve reciprocating paving operations, the end of the insertion rod 82 in this embodiment passes through the lifting frame 51 and is fixed with a frustum 86. An unlocking ring 87 is fixedly installed on the top of the machine 1. The unlocking ring 87 has a U-shaped structure, and the unlocking ring 87 abuts against the inclined surface of the frustum 86. That is, when the lifting frame 51 is reset, the frustum 86 at the end of the insertion rod 82 abuts against the unlocking ring 87, and the restriction of the unlocking ring 87 is retracted. The frustum 86 drives the insertion rod 82 to move, thereby driving the unlocking between the clamping block 83 and the ratchet 81. Thereafter, under the action of the tension spring 76, the swing arm 73 is reset, waiting for the next paving work.

[0039] In some embodiments, the film-pulling mechanism 2 includes a support frame 21, on the inner side of which a lower pressure roller 22 is rotatably connected, and on the side of the support frame 21 a motor 23 for driving the lower pressure roller 22 to rotate is fixed, and on both sides of the support frame 21 a slide groove is provided, in which a mounting plate 24 is slidably provided, and between the two mounting plates 24 an upper pressure roller 25 is rotatably connected, and on the top of the support frame 21 a screw 26 rotatable with the mounting plate 24 is threadedly connected, when working, the film is passed between the lower pressure roller 22 and the upper pressure roller 25, and the extrusion pressure between the two can be adjusted by the screw 26, and the motor 23 drives the lower pressure roller 22 to rotate so as to pull out the film on the film roller for user operation.

[0040] In summary, the present invention is composed of a film pulling mechanism 2, a cutting mechanism 3, a conveying mechanism 4 and a flattening mechanism 5. The system can automatically complete the film pulling, cutting and flattening operations, greatly improving the operating efficiency, and has significant advantages over the traditional manual operation method. Secondly, in the design of the flattening mechanism 5, two key components, a clamping roller 6 and a flattening roller 7, are used. The clamping roller 6 is responsible for clamping one side of the film, while the flattening roller 7 ensures that the film can be laid flatly on the upper surface of the glass by moving laterally. This design not only improves the film laying efficiency, but also ensures the flatness of the film laying.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
