Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive application, in particular to an environmentally friendly hot melt adhesive applicator for binding. Background Art

[0002] Environmentally friendly hot melt adhesive is a type of hot melt adhesive that has less impact on the environment during its manufacture and use. It usually refers to glue that uses less or no toxic or harmful ingredients, which reduces the negative impact on the environment and is more environmentally friendly than traditional hot melt adhesive. Environmentally friendly hot melt adhesive is often also used for book binding;

[0003] There are at least the following disadvantages in the use of existing environmentally friendly hot melt adhesive binding: in the binding process, the existing environmentally friendly hot melt adhesive is directly squeezed out by a hot melt gun and applied to the binding part of the book. The hot melt adhesive is in strips and cannot be evenly distributed in the binding part, thereby affecting the firmness after binding. Therefore, we introduce an environmentally friendly hot melt adhesive applicator for binding. Utility Model Content

[0007] Preferably, the second scraper device comprises a connecting seat, a through groove is formed at the front end of the connecting seat, a scraper is movably inserted in the through groove, and an adjusting screw is threadedly connected to the upper end of the connecting seat.

[0008] Preferably, the connecting seat is fixedly connected to the coating plate, and the adjusting screw is in contact with the upper end of the scraper.

[0009] By adopting the above technical solution, the adjusting screw can press and limit the adjusted scraper to prevent the scraper from moving in non-human circumstances.

[0010] Preferably, the connecting seat and the scraper are both arranged at an incline.

[0011] By adopting the above technical solution: the scraper is tilted, which makes it easier to scrape the overflowed glue.

[0012] Preferably, the coating plate has notches at the front and rear ends, and the two notches are inclined.

[0013] Preferably, a groove is formed at the lower end of the coating plate, and a plurality of partition plates are fixedly connected to the left portion and the right portion of the upper groove wall of the groove.

[0014] Preferably, the lower left parts and the lower right parts of several of the partition plates are both arc-surface structures, and the front left parts and the front right parts of several of the partition plates are both provided with through holes.

[0015] By adopting the above technical solution: a plurality of partition plates can guide the hot melt adhesive so that the hot melt adhesive is evenly spread.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] By setting a coating plate, after the binding part of the book is coated with hot melt adhesive, the coating plate is moved to the outside of the binding part by holding the anti-skid handle, and the anti-skid handle is pressed to make several partitions in the coating plate contact with the book, and the scraper on the No. 2 scraper device is adjusted to make the scraper contact with one side of the book, and the adjusting screw is rotated to limit the adjusted scraper, and then the No. 1 scraper device is adjusted by this method to make the scraper on the No. 1 scraper device contact with the other side of the book, and the anti-skid handle is pulled to the right to move the coating plate to the binding part of the book, and then with the cooperation of several partitions and the coating plate, the hot melt adhesive is evenly applied to the binding part. Under the action of the two scrapers, when glue overflows on both sides, the overflowed glue can be applied to both sides of the book to avoid waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figure 1-4 , the utility model provides a technical solution:

[0027] An environmentally friendly hot melt adhesive applicator for binding comprises a coating plate 1, a No. 2 glue scraper device 6 is fixedly connected to the lower front end of the coating plate 1, a No. 1 glue scraper device 4 is fixedly connected to the lower rear end of the coating plate 1, the No. 1 glue scraper device 4 and the No. 2 glue scraper device 6 have the same structure, the front and rear lower end of the coating plate 1 are both inclined structures, the No. 2 glue scraper device 6 and the No. 1 glue scraper device 4 are both inclinedly arranged, the upper end of the coating plate 1 is fixedly connected to a base 2, the base 2 is an "L"-shaped structure, the end of the base 2 away from the coating plate 1 is fixedly connected to a metal rod 5, and the end of the metal rod 5 away from the base 2 is fixedly connected to an anti-slip handle 3.

[0028] In this embodiment, the second scraper device 6 includes a connecting seat 61, a through groove 63 is opened at the front end of the connecting seat 61, a scraper 64 is movably inserted in the through groove 63, and an adjusting screw 62 is threadedly connected to the upper end of the connecting seat 61; the connecting seat 61 is fixedly connected to the coating plate 1, and the adjusting screw 62 is in contact with the upper end of the scraper 64; the connecting seat 61 and the scraper 64 are both inclined.

[0029] Through the above solution: pull 64 to move in 61, so that 64 contacts one side of the book, avoid glue overflow during the application process to increase the cleaning burden, and by rotating 62, 64 can be pressed and limited.

[0030] In this embodiment, the coating plate 1 has slots 11 at the front and rear ends, and the two slots 11 are inclined; a groove 12 is formed at the lower end of the coating plate 1, and a plurality of partition plates 14 are fixedly connected to the left and right upper groove walls of the groove 12; the left and right lower ends of the plurality of partition plates 14 are both arc structures, and through holes 13 are formed at the left and right front ends of the plurality of partition plates 14.

[0031] Through the above scheme: after a plurality of 14 come into contact with the book, it is possible to avoid 1 from directly coming into contact with the book. Under the action of a plurality of 14, it is possible to avoid the accumulation of hot melt adhesive and make the hot melt adhesive evenly distributed.

[0032] It should be noted that the utility model is an environmentally friendly hot melt adhesive applicator for binding. During use, after applying hot melt adhesive to the binding part of the book, the operator can easily hold the anti-slip handle 3 and smoothly move the coating plate 1 to the outside of the binding part. Then, press the anti-slip handle 3 lightly to make the multiple partitions 14 in the coating plate 1 fit tightly to the surface of the binding part. Next, adjust the position of the scraper 64 of the No. 2 scraper device 6 to ensure that it is in close contact with one side edge of the book, and fix the scraper 64 by rotating the adjustment screw 62. Use the same method to adjust the No. 1 scraper device 4 so that the scraper 64 on the other side also fits tightly to the other side edge of the book. Then, the operator slowly pulls the anti-slip handle 3 to the right, driving the coating plate 1 to move horizontally on the binding part of the book. Under the synergistic effect of the partition plates 14 and the coating plate 1, the hot melt adhesive can be evenly distributed in the binding part. If glue overflows on both sides, the two scrapers 64 will effectively guide the excess glue to the two sides of the book, thereby avoiding waste of resources and ensuring the accuracy and efficiency of gluing.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
