Description

Technical Field

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

[0002] Paper box laminating machines, also known as laminating or pasting machines, are mainly used to glue and bond pre-printed colored paper to materials such as cardboard. They are an important supporting equipment in the production of pre-printed paper boxes. Their working principle utilizes the natural tension of the paper to adhere the wet paper to cardboard or other substrates using glue. After drying, a smooth surface is formed, thereby enhancing the strength and appearance of the paper box.

[0003] According to CN222329157U, a paper box mounting machine first starts by starting the conveyor belt to transport the paper for mounting. At the same time, the threaded rod is rotated according to the size of the paper to adjust the baffle plate to a suitable spacing, thereby limiting the paper and preventing it from shifting. According to actual needs, an appropriate number of mounting blocks are installed at a suitable position at the bottom of the movable frame by fixing bolts and cooperating with the positioning holes. Then, the movable frame is driven downward by the hydraulic cylinder, so that the pressure roller presses the paper surface, further ensuring the stability of the paper during transportation.

[0004] The aforementioned conveyor belt can move the cardboard, but if too much glue is applied after the cardboard is coated, the glue may overflow and flow onto the conveyor belt, making cleaning inconvenient and causing subsequent cardboard to stick to the conveyor belt, affecting subsequent processes.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown, in this embodiment, a paper box mounting machine includes a mounting housing 1, a mounting frame 2 slidably connected inside the mounting housing 1, a rotating rod 3 rotatably connected inside the mounting frame 2, a scraper 4 fixedly connected to the surface of the rotating rod 3, a connecting spring 5 fixedly connected to the top of the scraper 4, a threaded hole 6 opened on the top of the mounting frame 2, an adjusting bolt 7 threadedly connected inside the threaded hole 6, a collecting groove 8 fixedly connected to the bottom of the mounting frame 2, and discharge ports 9 fixedly connected to the left and right sides of the mounting frame 2.

[0023] By setting scrapers 4 on both sides of the glue roller 19, excess glue can be scraped off after it is sprayed onto the glue roller 19 and moved into the collection tank 8 along the inclination angle of the scraper 4. This avoids excessive glue during the cardboard coating process. Since the scraper 4 is in contact with the glue, the uniformity of the glue on the surface of the glue roller 19 can be ensured. By rotating the adjusting bolt 7, it can be rotated in the threaded hole 6 and squeeze the scraper 4 downward. The connecting spring 5 is stretched, and the scraper 4 rotates through the rotating rod 3, thereby adjusting the distance between it and the glue roller 19 to adjust the thickness of the glue. This opens the solenoid valve in the discharge port 9, allowing the glue to be discharged for reuse and avoiding waste.

[0024] There are two rotating rods 3, and the number of shovels 4 corresponds to the number of rotating rods 3. The connecting spring 5 and the mounting bracket 2 are fixedly connected. The bottom of the adjusting bolt 7 is in contact with the shovel 4. A solenoid valve is installed inside the discharge port 9.

[0025] A first motor 10 is fixedly connected to the back of the mounting housing 1. A bidirectional lead screw 11 is fixedly connected to the output shaft of the first motor 10. A threaded sleeve 12 is threadedly connected to the surface of the bidirectional lead screw 11. A guide rod 13 is fixedly connected to the inner wall of the mounting housing 1. A slider 14 is slidably connected to the surface of the guide rod 13. A rotating plate 15 is rotatably connected to the bottom of the slider 14 and the threaded sleeve 12. A rotating base 16 is rotatably connected to the bottom of the rotating plate 15.

[0026] By starting the first motor 10, its output shaft drives the bidirectional lead screw 11 to rotate. The two threaded sleeves 12 slide on its surface and move closer or further away from each other. At the same time, the two sliders 14 slide on the guide rod 13, the rotating plate 15 rotates, and drives the mounting frame 2 to move up and down inside the mounting housing 1 to adjust its height, so as to facilitate the application of glue to the glue roller 19 and the cardboard and avoid glue splashing when the nozzle is applied.

[0027] The bidirectional lead screw 11 is rotatably connected to the mounting housing 1, and there are two threaded sleeves 12. The number of sliders 14 and threaded sleeves 12 are corresponding. The rotary seat 16 is fixedly connected to the mounting bracket 2.

[0028] The top of the mounting bracket 2 is provided with a through groove 17. The second motor 18 is fixedly connected to the side of the mounting bracket 2 near the first motor 10. The output shaft of the second motor 18 is fixedly connected to a rubber roller 19.

[0029] By starting the second motor 18, its output shaft drives the glue roller 19 to rotate, so that when the glue is applied to the surface of the discharge plate 24, the glue can be evenly applied to its surface, avoiding the accumulation of glue in the same area.

[0030] A storage tank 20 is fixedly connected to the side of the mounting housing 1 away from the first motor 10. A pump body 21 is fixedly attached to the top of the storage tank 20. A conduit 22 is fixedly connected to the side of the pump body 21 away from the mounting housing 1. A connecting pipe 23 is fixedly connected to the top of the pump body 21. A discharge plate 24 is fixedly connected to the end of the connecting pipe 23 away from the pump body 21. The discharge plate 24 is fixedly connected to the mounting housing 1.

[0031] An ionizing air bar 25 is fixedly connected to the inner wall of the mounting housing 1, and a support frame 26 is fixedly connected to the bottom of the mounting housing 1. A conveyor belt 27 is installed inside the support frame 26.

[0032] By setting up a conveyor belt 27, the paperboard can be easily transported. An ion bar 25 is set inside the mounting housing 1, which can generate air masses with positive and negative charges to neutralize the static electricity on the surface of the paperboard, thereby eliminating static electricity and reducing the adsorption of impurities.

[0033] This utility model provides a paper box mounting machine, the specific working principle of which is as follows:

[0034] In use, the cardboard is placed on the conveyor belt 27. The conveyor belt 27 operates and moves the cardboard. The pump body 21 is started, so that the glue inside the storage tank 20 is removed through the conduit 22 and transported to the discharge plate 24 through the connecting pipe 23. The glue is applied to the glue roller 19 through the nozzle at the bottom of the plate. At the same time, the second motor 18 is started, and its output shaft drives the glue roller 19 to rotate, so that the glue is evenly applied to the surface of the glue roller 19. At the same time, the scraper 4 contacts the glue and scrapes off the excess glue. The scraper moves along the angle of the scraper 4 into the collection tank 8. When the cardboard moves to the bottom of the mounting frame 2, the first motor 10 operates, and its output shaft drives the bidirectional lead screw 11 to rotate. The two threaded sleeves 12 slide on its surface and move closer to each other. At the same time, the two sliders 14 slide on the guide rod 13. The rotating plate 15 rotates and drives the mounting frame 2 to move down inside the mounting housing 1 and contact the cardboard, thereby completing the glue application work of the cardboard.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
