[0033] The positioning mechanism 9 comprises a mounting base plate 9.1, a positioning clamp plate 9.2 and a movable clamp plate 9.3 are mounted on the upper side of the mounting base plate 9.1, supporting transverse plates 9.6 are mounted in the middle of both sides of the movable clamp plate 9.3, and U-shaped grooves 9.7 for matching with the supporting transverse plates 9.6 are mounted in the middle of both sides of the positioning clamp plate 9.2.

[0034] The glue coating mechanism includes a pump body 16 installed on the upper side of the inverted U-shaped frame 10, the upper end of the pump body 16 is a feed end and is connected with a feed pipe 17, the lower end of the pump body 16 is a discharge end and is connected with a distribution bin 18, and a plurality of discharge pipes 19 are installed on one side of the distribution bin 18;

[0035] The scraping mechanism includes a threaded tube 11 installed on the upper side of an inverted U-shaped frame 10, a threaded shaft 12 is passed through the inside of the threaded tube 11, a connecting cross plate 13 is rotatably installed at the lower end of the threaded shaft 12, a scraper 14 is installed on the lower side of the connecting cross plate 13, and collecting pipes 15 are provided on the two side walls of the scraper 14.

[0036] Through the above structure, the sealing strip is transported by the feeding mechanism, and the sealing strip is clamped and limited by the cooperation of the positioning clamping plate 9.2 and the movable clamping plate 9.3 in the positioning mechanism 9, and the sealing strip is lifted by the supporting cross plate 9.6 to prevent the sealing strip from deflecting and turning over during the transportation process, so as to ensure that the subsequent glue can be normally applied. After the pump body 16 works, the glue is sent to the distribution bin 18 through the feeding pipe 17, and the glue is sent to the back side of the sealing strip through the multiple groups of discharge pipes 19 on the upper side of the distribution bin 18. The threaded tube 11 is rotated to move the scraper 14 connecting the cross plate 13 and the lower side downward to a suitable height on the upper side of the sealing strip, and the glue on the back side of the sealing strip is scraped flat by the scraper 14, and the glue scraped out by the scraper 14 is sent to the collecting hopper 22 through the collecting pipe 15, and the collected glue is discharged and recycled through the discharge pipe 23. The specific structure is as follows:

[0037] Combined with Figure 4As shown, a threaded shaft 9.4 is rotatably installed at the lower part of the movable splint 9.3, and the other end of the threaded shaft 9.4 cooperates with the thread to pass through the positioning splint 9.2 and is installed with a twisting block 9.5. Two groups of limit sliders 9.8 are installed on the lower side of the movable splint 9.3, and two groups of limit slide grooves 9.9 that cooperate with the limit sliders 9.8 are provided on the upper side of the mounting base plate 9.1.

[0038] Through the above structure, the distance between the movable splint 9.3 and the positioning splint 9.2 is adjusted according to the width of the sealing strip, and the twisting block 9.5 is rotated to drive the threaded shaft 9.4 to rotate. The threaded shaft 9.4 is threadedly connected with the movable splint 9.3, and the movable splint 9.3 can be driven to move through the threaded shaft 9.4. The two sets of limit sliders 9.8 are respectively limited in the limit slide grooves 9.9 to prevent the movable splint 9.3 from rotating with the threaded shaft 9.4. During the movement of the movable splint 9.3, the supporting cross plate 9.6 slides in the U-shaped groove 9.7, which will not affect the adjustment of the distance between the movable splint 9.3 and the positioning splint 9.2.

When the connecting cross plate 13 moves up and down, the connecting cross plate 13 is limited by two groups of positioning rods 7 to prevent the connecting cross plate 13 and the scraper 14 from rotating with the threaded shaft 12. The scraper 14 with a V-shaped structure can gather excess glue to the middle of the scraper 14 and accumulate the glue on the upper side of the receiving cross plate 8.

[0042] Through the above structure, the motor 5 drives the roller 4 to rotate and the sealing strip is transported. The sealing strip can be clamped by the cooperation of the roller 2 6 and the roller 4, and the sealing strip will not separate from the upper side of the roller 4, making the feeding more stable.

[0045] Through the above structure of the second embodiment, the collecting hopper 22 can be controlled to heat by the temperature controller 25 to prevent the glue collected in the collecting hopper 22 from solidifying after drying. When the control valve 24 is opened, it is not convenient to discharge from the discharge pipe 23 at the bottom of the collecting hopper 22.

[0046] The specific usage is as follows:

[0047] The sealing strip is placed between the roller 1 4 and the roller 2 6 on the feeding side, and the roller 1 4 is driven to rotate by the motor 5 to feed the sealing strip, and the sealing strip is moved to the upper side of the supporting horizontal plate 9.6 inside the two sets of positioning mechanisms 9, and the distance between the moving clamping plate 9.3 and the positioning clamping plate 9.2 in the positioning mechanism 9 is adjusted to a suitable width, and the sealing strip is limited, and the sealing strip is continuously conveyed to the upper side of the roller 1 4 on the discharging side, and the sealing strip is discharged through the roller 1 4;

[0048] When the sealing strip is conveyed, the feeding pipe 17 is connected to the external glue tank, the pump body 16 is started, and the glue is delivered to the distribution bin 18 through the pump body 16. The multiple groups of discharge pipes 19 on the distribution bin 18 are blocked in advance through the sealing cover 20, and the width of the glue discharge is adjusted. The glue is delivered to the back of the sealing strip through the remaining multiple groups of discharge pipes 19. During the sealing strip conveying process, the scraper 14 with a height adjusted in advance spreads the glue horizontally on the back of the sealing strip, and the flat-bottomed V-shaped scraper 14 gathers the excess glue to the middle, accumulates the glue on the upper side of the receiving cross plate 8, and delivers the glue to the collecting hopper 22 through the collecting pipe 15 and heats it to prevent the glue from solidifying. The material control valve 24 is opened, and the collected glue can be discharged through the discharge pipe 23 for recycling.
