Description

Technical Field

[0001] This utility model relates to the field of gluing machine technology, specifically to a gluing machine. Background Technology

[0002] A laminating machine is an essential piece of equipment in the offset printing industry. It primarily works by laminating polyester film coated with hot melt adhesive to achieve a sealing process. During lamination, the adhesive rollers are heated and pressed together, ensuring a strong bond between the film and items such as photos and documents. From a design perspective, the main components of a laminating machine include front and rear adhesive rollers, a heating and temperature control system, a drive system, and an operation control panel. Its working principle mainly involves the lamination of the polyester film coated with hot melt adhesive, with these components working together to complete the sealing process.

[0003] Traditional laminating machines use heating and clamping of rubber rollers to apply adhesive to items. However, during the printing process, unevenness or dust on the items can lead to uneven sealing, resulting in residual adhesive on the rollers and preventing complete sealing of the items. Therefore, a new laminating machine was designed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a gluing machine, including a shell and a collection frame disposed inside the shell. A placement plate is installed inside the collection frame, and multiple placement platforms are fixedly connected to the placement plate. A connecting column is fixedly connected to the top of the multiple placement platforms. An installation groove is opened inside the connecting column, and a scraper is slidably connected to the installation groove. Limiting protrusions are integrally formed on both sides of the scraper, and a limiting block is provided on the installation groove to limit the scraper. Two symmetrical metal columns are fixedly connected to the placement plate, and a heating wire is fixedly connected between the two metal columns.

[0006] Furthermore, two symmetrical rubber rollers are provided on the inner side of the outer casing. The rubber rollers are connected to a telescopic rod. The other end of the telescopic rod is sleeved with a mounting post. The mounting post is fixedly connected to a connecting plate. The other side of the connecting plate is rotatably connected to a main shaft.

[0007] Furthermore, a fixing plate is fixedly connected to one side of the outer shell, a limit rod is slidably connected to the fixing plate, and a spring is sleeved on the limit rod.

[0008] Furthermore, a fixing plate is fixedly connected to one side of the outer shell, a limiting rod is slidably connected to the fixing plate, a spring is sleeved on the limiting rod, a connecting seat is fixedly connected to one end of the spring, a limiting rod is fixedly connected to the other end of the spring, and one end of the limiting rod extends through the connecting seat to the bottom of the main rotating shaft.

[0019] 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.

[0020] Please see Figure 1-5 This utility model provides a technical solution: including a shell 6 and a collection frame 1 set inside the shell 6. A placement plate 4 is installed inside the collection frame 1. Multiple placement platforms 12 are fixedly connected to the placement plate 4. A connecting column 13 is fixedly connected to the top of the multiple placement platforms 12. An installation groove 17 is opened inside the connecting column 13. A scraper 11 is slidably connected to the installation groove 17. Limiting protrusions 16 are integrally formed on both sides of the scraper 11. Limiting blocks are set on the installation groove 17 to limit the scraper 11. Two symmetrical metal columns 14 are fixedly connected to the placement plate 4. A heating wire 15 is fixedly connected between the two metal columns 14.

[0021] In practice, when adhesive removal is required, the scraper 11 is inserted laterally into the mounting groove 17. At this time, the limiting protrusion 16 should be located below the limiting block in the mounting groove 17 and fixed vertically to the scraper 11. Then, the motor on the metal column 14 is turned on, and the current passes through the heating wire 15 between the two metal columns 14 to generate heat. To ensure better heat conduction, a heat-conducting plate can be added to the scraper 11 on the heating wire 15. At the same time, a protective shell can be added to the heating wire 15 to increase its service life.

[0022] See Figure 1 Specifically, a glue-applying roller 2 is sleeved on the glue roller 3, and the glue-applying roller 2 has an integrally formed grid pattern.

[0023] In practice, when it is necessary to replace the glue-applying roller 2, press one side of the glue roller 3. At this time, the telescopic rod 9 extends and retracts, and the glue roller 3 can be taken out from one side. At this time, the glue-applying roller 2 can be replaced.

[0024] See Figure 2 The inner side of the outer casing 6 is provided with two symmetrical rubber rollers 3. The rubber rollers 3 are connected to a telescopic rod 9. The other end of the telescopic rod 9 is sleeved with a mounting post 8. The mounting post 8 is fixedly connected to a connecting plate 5. The other side of the connecting plate 5 is rotatably connected to a main rotating shaft 20.

[0025] In practice, the telescopic rod 9 is connected to the mounting column 8, and the mounting column 8 is fixedly connected to the connecting plate 5. When the connecting plate 5 rotates, it drives the rotating shaft 7 to rotate at the same time, causing the rubber roller 3 to move up and down.

[0026] See Figure 3Two symmetrical metal pillars 14 are fixedly connected to the placement plate 4, and a heating wire 15 is fixedly connected between the two metal pillars 14. Multiple connecting pillars 13 are fixedly connected to the placement plate 4.

[0027] In practice, a motor is installed under the metal column 14 to generate current. The current connects the two metal columns 14, causing the heating wire 15 between the metal columns 14 to generate heat. In order to enhance the heat conduction effect, a heat-conducting plate can be added to the scraper 11 on the heating wire 15.

[0028] See Figure 4 The scraper 11 has integrally formed limiting protrusions 16 on both sides. The limiting protrusions 16 are semi-circular arc-shaped, and the mounting groove 17 is provided with block-shaped limiting blocks.

[0029] In practice, a guide groove can be added to the scraper 11 to increase the efficiency of scraping glue. At the same time, the shape of the limiting protrusion 16 can be changed to improve the stability of the limiting position. When in use, the limiting protrusion 16 is placed below the limiting block. The limiting protrusion 16 and the limiting block work together to limit the position. Then, the scraper 11 is pushed inward along the mounting groove 17.

[0030] See Figure 5 A fixing plate 21 is fixedly connected to one side of the outer shell 6. A limit rod 18 is slidably connected to the fixing plate 21. A spring 23 is sleeved on the limit rod 18. A connecting seat 19 is fixedly connected to one end of the spring 23. The limit rod 18 is fixedly connected to the other end of the spring 23. One end of the limit rod 18 extends through the connecting seat 19 to the bottom of the main rotating shaft 20.

[0031] In practice, a rubber cap can be added to one end of the limiting rod 18 to make it easier to pick up, and irregular textures can be added to the knob 22 to increase friction. When in use, lift the limiting rod 18 and rotate the knob 22. After rotation, the spring 23 will cause the limiting rod 18 to spring back, thus fixing the main shaft 20.

[0032] Specifically, a drive shaft 10 is connected to one side of the connecting plate 5, and a knob 22 is rotatably connected to the other side of the drive shaft 10. The knob 22 is integrally formed with anti-slip texture. This arrangement facilitates driving the drive shaft 10 to rotate and makes it easy to apply force.

[0033] Working principle: When needed, the collection frame 1 is placed inside the outer casing 6. The scraper 11 is pushed from the side into the mounting slot 17 inside the connecting column 13. At this time, the induction motor is turned on, driving the glue roller 3 to rotate. Then, the item to be glued is placed in. At this time, the motor on the metal column 14 is turned on, causing the heating wire 15 between the two metal columns 14 to generate heat, and at the same time, the item is heat-sealed. The scraper 11 also scrapes off the uneven glue on the glue roller 2. After the sealing is completed, the limiting rod 18 is pulled up, and the knob 22 is turned to change the position of the two glue rollers 3. Then, the spring 23 springs the limiting rod 18 back. Then the collection frame 1 can be removed from the outer casing 6 for cleaning, so that the glued object is more intact and has a longer service life.
