Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of SGP film splicing, in particular to SGP film splicing equipment. Background Art
[0002] SGP film is a new type of interlayer film for laminated glass. Compared with the commonly used PVB film, it has higher tear strength and adhesion, and is more expensive. As the laminated glass with SGP film as the interlayer has excellent properties, it is currently widely used in glass curtain walls, open-air ceilings, cash transporters, banks, prisons and other places.
[0003] However, the following two problems are encountered in the production of SGP laminated glass: first, due to the limitations of the manufacturing process and transportation conditions of the SGP material itself, the size of the finished product cannot be too large. When it is necessary to produce a large-format SGP laminated glass, the current manufacturers usually adopt two or even more SGP films in the middle of every two large-format glasses, closely arranging them together, and then fixing them with high-temperature resistant tapes, and making large-format laminated glass through pre-pressing and steaming processes, and this process is inefficient; secondly, SGP films are expensive, and a lot of SGP edge materials inevitably left in the traditional production process are difficult to fully utilize, resulting in material waste and increased production costs. The above-mentioned method of fixing multiple films with tapes to produce large-sized SGP laminated glass not only increases production costs due to too many joints, but also causes obvious bubble marks (at the joint of two SGP films) inside the produced SGP laminated glass.
[0004] Therefore, we propose a SGP film splicing device. Utility Model Content
[0005] The purpose of the utility model is to provide a SGP film splicing device to solve the problems raised in the above background technology.

[0007] Optionally, guide slide bars are fixedly installed at the top of the fixed bracket on both sides of the threaded rod, and both ends of the guide slide bars are slidably connected through the displacement block.
[0008] Optionally, a first bevel gear is fixedly installed at the output end of the displacement motor, and a second bevel gear located on the front surface of the fixed bracket is fixedly installed at one end of the threaded rod, and the second bevel gear meshes with the first bevel gear.

[0011] Optionally, the length of the telescopic rod is greater than the length of the movable groove, the telescopic rod is slidably connected through the bottom of the movable groove, and the length of the flattening roller is greater than the width of the movable groove.
[0012] Optionally, the center lines of the threaded rod, the lifting cylinder, and the ultrasonic welding head are located in the same vertical plane.
[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] For this SGP film splicing device, by setting the threaded rod and the displacement block, the SGP films to be spliced and welded are cut and then placed on the splicing table, the welding seams are aligned, the displacement motor and the lifting cylinder are started, so that the ultrasonic welding head is close to the splicing seam. As the displacement motor drives the threaded rod to rotate, the displacement block moves along the guide slide bar to weld the splicing seam, which can meet the production of large-sized laminated glass from two or more SGP films, with high production efficiency and no defects such as interlayer bubbles in the processed products.
[0015] For this SGP film splicing device, by setting the movable groove and the flattening roller, when the lifting cylinder pushes the ultrasonic welding head to descend, the movable groove and the flattening roller move down together. The bottom of the flattening roller contacts the SGP film. As the flattening roller moves down, the movable plate squeezes the downward pressure spring, and the flattening roller further compresses the SGP film, so that the flattening roller flattens the SGP films on both sides of the ultrasonic welding head before and after welding to prevent the SGP film from shifting during the welding process.

[0021] Please refer to Figures 1 to 3, the utility model provides an SGP film splicing device, which includes a bottom plate 1. A splicing table 2 is fixedly installed at the top of the bottom plate 1. Fixed brackets 3 are fixedly installed at the top of the bottom plate 1 on the front and rear sides of the splicing table 2. A threaded rod 5 is rotatably connected to the middle of the top of the fixed bracket 3. A displacement motor 4 is fixedly installed on the front of one of the fixed brackets 3. The output end of the displacement motor 4 is in transmission connection with one end of the threaded rod 5. A first bevel gear 17 is fixedly installed at the output end of the displacement motor 4. A second bevel gear 18 is fixedly installed at one end of the threaded rod 5 on the front of the fixed bracket 3. The second bevel gear 18 meshes with the first bevel gear 17. The threaded rod 5 is threadedly connected with a displacement block 6 located between the two fixed brackets 3. Guide slide rods 16 are fixedly installed at the top of the fixed brackets 3 on both sides of the threaded rod 5. The guide slide rods 16 are slidably connected through the two ends of the displacement block 6. A lifting cylinder 7 is fixedly installed at the bottom of the displacement block 6. A movable end at the bottom of the lifting cylinder 7 is fixedly installed with a mounting frame 8. An ultrasonic welding head 9 is fixedly installed at the top of the mounting frame 8. The central lines of the threaded rod 5, the lifting cylinder 7 and the ultrasonic welding head 9 are located in the same vertical plane. Moving grooves 10 are fixedly installed on the front and rear sides of the mounting frame 8. Flattening rollers 15 are movably arranged at the bottoms of the moving grooves 10. By arranging the threaded rod 5 and the displacement block 6, the SGP films to be spliced and welded are cut and then placed on the splicing table 2. The welding seams are aligned. The displacement motor 4 and the lifting cylinder 7 are started, so that the ultrasonic welding head 9 is closely attached to the splicing seam. As the displacement motor 4 drives the threaded rod 5 to rotate, the displacement block 6 moves along the guide slide rod 16 to weld the splicing seam, which can meet the production of large-sized laminated glass from two or more SGP films. The production efficiency is high, and the products obtained by processing will not have defects such as interlayer bubbles.
[0022] A movable plate 11 is slidably connected inside the movable slot 10. A telescopic rod 13 is fixedly installed at the bottom of the movable plate 11. A rolling bracket 14 is fixedly installed at the bottom of the telescopic rod 13. A flattening roller 15 is rotatably connected to the bottom of the rolling bracket 14. A downward pressure spring 12 is arranged inside the movable slot 10. The top of the downward pressure spring 12 is fixedly installed with the top inside the movable slot 10. The top of the downward pressure spring 12 is in tight contact with the top of the movable plate 11. The length of the telescopic rod 13 is greater than the length of the movable slot 10. The telescopic rod 13 is slidably connected through the bottom of the movable slot 10. The length of the flattening roller 15 is greater than the width of the movable slot 10. By providing the movable slot 10 and the flattening roller 15, when the lifting cylinder 7 pushes the ultrasonic welding head 9 to descend, the movable slot 10 and the flattening roller 15 move downward accordingly. The bottom of the flattening roller 15 contacts the SGP film. As the flattening roller 15 moves downward, the movable plate 11 squeezes the downward pressure spring 12, and the flattening roller 15 further compresses the SGP film, so that the flattening roller 15 flattens the SGP film on both sides of the ultrasonic welding head 9, preventing the SGP film from shifting during the welding process.
[0023] Working principle:
[0024] Place the cut SGP films to be spliced and welded on the splicing table 2, align the welding seams, start the displacement motor 4 and the lifting cylinder 7, so that the ultrasonic welding head 9 is in close contact with the splicing seam. When the lifting cylinder 7 pushes the ultrasonic welding head 9 to descend, the movable slot 10 and the flattening roller 15 move downward accordingly. The bottom of the flattening roller 15 contacts the SGP film. As the flattening roller 15 moves downward, the movable plate 11 squeezes the downward pressure spring 12, and the flattening roller 15 further compresses the SGP film, so that the flattening roller 15 flattens the SGP film on both sides of the ultrasonic welding head 9, preventing the SGP film from shifting during the welding process. As the displacement motor 4 drives the threaded rod 5 to rotate, the displacement block 6 moves along the guiding slide rod 16 to weld the splicing seam, which can meet the production of large-sized laminated glass from two or more SGP films. The production efficiency is high, and the products obtained by processing will not have defects such as interlayer bubbles.
