Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1-4 A sealing strip bonding machine includes two symmetrical support frames 1, and a conveyor belt 2 for conveying the bonding substrate is provided between the two support frames 1. The upper part of the conveyor belt 2 is provided with a drive roller 3, a guide roller 5 and a pressing roller 6 in sequence according to the conveying direction. The drive roller 3 is used to cooperate with the conveyor belt 2 to convey the bonding substrate, the guide roller 5 is used to guide the processed sealing strip, and the pressing roller 6 is used to press the processed sealing strip and the bonding substrate together.

[0029] The specific implementation method in this embodiment is as follows: The conveyor belt 2 mentioned above is a known prior art technology. It is driven by a motor to bond the sealing strip and the adhesive substrate. The adhesive substrate is placed between the conveyor belt 2 and the drive roller 3. The conveyor belt 2 and the drive roller 3 drive the adhesive substrate. At the same time, the guide roller 5 and the pressure roller 6 are adapted to the shape of the sealing strip. The sealing strip is unwound by an external unwinding device. The sealing strip is then bonded by a hot melt device or an adhesive coating device. The hot melt device heats and bonds the sealing strip, while the adhesive coating device applies adhesive to the side of the sealing strip to be bonded. The two methods are selected according to the actual situation, and both are known prior art technologies. Subsequently, the processed sealing strip and adhesive substrate are conveyed to the position of the pressure roller 6. The pressure roller 6 presses and bonds the sealing strip and the adhesive substrate, completing the bonding process of the sealing strip. By bonding the sealing strip in the above way, it is possible to quickly bond long sealing strips and adhesive substrates, and improve the bonding efficiency of the sealing strip and the adhesive substrate.

[0030] Example 2

[0031] Please see Figure 1 , Figure 2 and Figure 4This embodiment includes the above embodiment, and further includes: two sets of symmetrical positioning and guiding units are provided on the conveyor belt 2. The two sets of positioning and guiding units are used to guide the sealing ring and the adhesive substrate before and after bonding, respectively. Each set of positioning and guiding units includes two symmetrical limiting plates 4. The side of the limiting plate 4 is rotatably connected to a second adjusting threaded rod 14 that passes through the bearing frame 1 and is threadedly connected to the bearing frame 1. The side of the second adjusting threaded rod 14 is threadedly connected to a second limiting nut 15. The side of the limiting plate 4 is fixedly installed with a guide limiting rod 16 that passes through the bearing frame 1. The length of the guide limiting rod 16 is adapted to the length of the second adjusting threaded rod 14. A support plate 17 is fixedly installed between the two bearing frames 1. The upper part of the support plate 17 abuts against the upper part of the inner part of the conveyor belt 2.

[0032] In this embodiment, the sealing strip and adhesive substrate are conveyed to the positions of the two limiting plates 4. The two limiting plates 4 convey the sealing strip and adhesive substrate together, improving the bonding quality between them. When different widths of sealing strips and adhesive substrates need to be bonded, the second adjusting threaded rod 14 is rotated. As the second adjusting threaded rod 14 rotates, the position of the limiting plate 4 is adjusted. Then, the second limiting nut 15 is locked to limit and fix the position of the second adjusting threaded rod 14, thus improving the applicability of the bonding device. When the position of the limiting plate 4 is adjusted, the guide limiting rod 16 moves accordingly to limit the position of the limiting plate 4. The support plate 17 is used to support the conveyor belt 2 to prevent the conveyor belt 2 from sagging when the sealing strip and adhesive substrate are pressed together, thereby improving the pressing effect between the sealing strip and adhesive substrate.

[0033] Example 3

[0034] Please see Figure 1 and Figure 3 This embodiment includes all the above embodiments, and further includes: several mounting brackets 7 and two symmetrical fixed plates 8 are fixedly installed on the upper part of each of the two support frames 1; the guide roller 5 is rotatably connected between the two fixed plates 8; the mounting bracket 7 is used to install the pressure roller 6 and the transmission roller 3; one side of the mounting bracket 7 is provided with a drive motor 9 for driving the transmission roller 3 or the pressure roller 6; the opposite sides of the transmission roller 3 or the pressure roller 6 are rotatably connected with adjusting seats 10; the opposite sides of the mounting bracket 7 are provided with adjusting grooves 11 adapted to the adjusting seats 10. The upper end of the frame 7 is rotatably connected to a first adjusting threaded rod 12 that extends into the adjusting groove 11. The first adjusting threaded rod 12 passes through the adjusting seat 10 and is threadedly connected to the adjusting seat 10. The upper side of the first adjusting threaded rod 12 is threadedly connected to a first limiting nut 13. The drive motor 9 is fixedly installed on one side of the adjusting seat 10 and is used to drive the transmission roller 3 or the pressure roller 6 to rotate. There are several pressure rollers 6, and the several pressure rollers 6 are arranged in the conveying direction. The distance between each pressure roller 6 and the conveyor belt 2 decreases in an arithmetic sequence.

[0035] In this specific embodiment, when it is necessary to bond sealing strips and adhesive substrates of different thicknesses, the first adjusting threaded rod 12 is rotated. When the first adjusting threaded rod 12 rotates, it drives the adjusting seat 10 to slide in the adjusting groove 11. The two adjusting seats 10 drive the transmission roller 3 or the pressing roller 6 to move. Then, the first limiting nut 13 is locked to limit and fix the position of the first adjusting threaded rod 12. The drive motor 9 is used to drive the transmission roller 3 or the pressing roller 6, which can convey and bond sealing strips and adhesive substrates of different thicknesses, thus improving the applicability of the bonding device. The distance between each pressing roller 6 and the conveyor belt 2 is not equal. Several pressing rollers 6 are arranged in the conveying direction. The distance between each pressing roller 6 and the conveyor belt 2 decreases in an arithmetic sequence, gradually pressing the sealing strip and the adhesive substrate together to prevent damage to the sealing strip or the adhesive substrate and improve the quality of the sealing strip after bonding.
