[0025] like Figure 2 As shown, the tops of the feed trough 2, the discharge trough 3 and the conveying roller 5 are all located on the same horizontal line.

[0026] The effects achieved by the above components are: by arranging the feed chute 2, the discharge chute 3 and the top of the conveying roller 5 on the same horizontal line, the horizontality of the conveying of the cardboard is ensured, which is beneficial to the uniformity of the gluing of the cardboard.

[0027] like Figure 5As shown, a second scraper plate 19 is arranged inside the shell 1, and the side of the second scraper plate 19 close to the conveying roller 5 contacts the surface of the conveying roller 5, and positioning rods 20 are fixedly installed on both sides of the second scraper plate 19.

[0028] The effects achieved by the above components are as follows: by setting the second scraper plate 19 for scraping glue on the surface of the conveying roller 5, it is avoided that the conveying of the cardboard by the conveying roller 5 is affected; under the action of the compression spring 21, pressure is applied to the positioning rod 20, and then the positioning rod 20 drives the second scraper plate 19 to fit closely with the surface of the conveying roller 5, thereby improving the scraping effect of the second scraper plate 19 on the surface of the conveying roller 5.

[0029] like Figure 5 As shown, a stopper 22 is fixedly mounted on the surface of the positioning rod 20 , and the stopper 22 is respectively clamped on two sides of the housing 1 .

[0030] The effect achieved by the above components is: by setting the block 22 to limit the positioning rod 20, the positioning rod 20 is prevented from shifting and shaking inside the positioning inclined groove 23, thereby further improving the use stability of the second scraper plate 19 and improving the scraping effect of the second scraper plate 19 on the surface of the conveying roller 5.

[0031] like Figure 4 As shown, a support frame 9 is fixedly installed inside the housing 1 and directly below the first scraper plate 10 , and the top of the support frame 9 and the top of the conveying roller 5 are located on the same horizontal line.

[0032] The effects achieved by the above components are: by providing the support frame 9 to support the cardboard conveyed by the conveying roller 5, deformation of the cardboard is avoided and the stability of the cardboard is improved when scraping off excess glue.

[0033] like Figure 1 and Figure 2 As shown, a mounting socket 24 is provided on the front of the housing 1 , and a glue collecting tray 25 is provided inside the housing 1 . The front of the glue collecting tray 25 passes through the mounting socket 24 and extends to the outside of the housing 1 .

[0034] The effect achieved by the above components is: by setting up the glue collecting tray 25 to collect the dripping glue, the glue is prevented from dripping directly to the bottom of the inner cavity of the shell 1, which makes it difficult to clean the glue. Under the action of the installation socket 24, the glue collecting tray 25 is convenient to install and remove, and then the glue collected in the glue collecting tray 25 is convenient to clean, so that the glue collecting tray 25 is convenient for the next use.

[0035] like Figure 6As shown, a convex plate 27 is fixedly installed on the front of the shell 1, a tension spring 28 is fixedly installed on the top of the convex plate 27, a circular plate is fixedly installed on the top of the tension spring 28, and an inclined clamping rod 29 is fixedly installed on the bottom of the circular plate. A clamping groove 26 is provided at the top of the rubber collecting tray 25 and directly below the convex plate 27, and the bottom of the inclined clamping rod 29 passes through the convex plate 27 and is clamped in the inside of the clamping groove 26.

[0036] The effect achieved by the above components is: by setting a tension spring 28 to apply pressure to the inclined clamping rod 29, the inclined clamping rod 29 always maintains a tendency to move downward, thereby improving the stability of the inclined clamping rod 29 being clamped in the slot 26, preventing the bottom of the inclined clamping rod 29 from escaping from the slot 26, and further improving the installation stability of the rubber collection tray 25.

[0037] The working principle of this paper mounting machine with a scraping mechanism:

[0038] First, the height of the first scraper 10 needs to be adjusted according to the thickness of the cardboard. The operator rotates the drive disk 14, and the drive disk 14 drives the rotating rod 12 to rotate, and then the rotating rod 12 drives the two gears 13 to rotate, and the gear 13 drives the toothed plate 11 to move up, and the toothed plate 11 pulls the first scraper 10 up to adjust the first scraper 10 to a suitable height. If it is necessary to move the first scraper 10 down, the pawl 16 is moved so that one side of the pawl 16 is separated from the surface of the ratchet 15. At this time, the drive disk 14 can be reversed, and the first scraper 10 can be moved forward and backward. The plate 10 is adjusted downward, and after the adjustment is completed, the pawl 16 is released, so that the pawl 16 rebounds and is engaged with the surface of the ratchet 15, and the cardboard is inserted from the feed slot 2 into the interior of the housing 1, so that one side of the cardboard moves to the surface of the conveying roller 5, and the conveying roller 5 is driven to rotate under the action of the motor 4, and then the conveying roller 5 conveys the cardboard. When the cardboard passes under the glue box 6, the glue nozzle 8 evenly discharges glue to coat the cardboard. After coating, the cardboard continues to be conveyed and moves to the top of the support frame 9. When the cardboard passes under the first scraper plate 10 When the first scraper 10 scrapes the paperboard, the paperboard is moved out of the housing 1 from the discharge trough 3, and the scraped glue drips into the glue collecting tray 25. At the same time, when the conveying roller 5 rotates, the compression spring 21 squeezes the positioning rod 20, so that the second scraper 19 is tightly attached to the surface of the conveying roller 5, and the conveying roller 5 is scraped. The scraped glue also drips into the glue collecting tray 25. When the glue in the glue collecting tray 25 is collected by more than half, it is necessary to clean and pour out the glue in time, and the inclined clamping rod 29 is pushed upward. The bottom of the inclined clamping rod 29 is separated from the inside of the slot 26, and then the glue collecting tray 25 is taken out. After the glue liquid inside the glue collecting tray 25 is processed, the glue collecting tray 25 is installed in the inside of the shell 1, and the glue collecting tray 25 is inserted into the inside of the installation socket 24 and pushed into the inside of the shell 1. The top of the glue collecting tray 25 will press the inclined clamping rod 29 upward until the slot 26 moves to the bottom of the inclined clamping rod 29, and the inclined clamping rod 29 is bounced open under the elastic force of the tension spring 28, so that the bottom of the inclined clamping rod 29 is clamped in the inside of the slot 26.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
