Description

Technical Field

[0001] This utility model relates to the field of cigarette box paperboard production technology, specifically to a gluing device for cigarette box paperboard. Background Technology

[0002] The gluing device for cigarette box cardboard is mainly used to apply glue to the cardboard accurately and efficiently during the production process to ensure that the cardboard can be properly bonded in subsequent processes. The design of traditional gluing devices usually relies on two roller systems, with a larger diameter roller and a smaller diameter roller working together to apply glue evenly to the cardboard. When the cardboard passes between the two rollers, the larger diameter roller is responsible for carrying the glue and transferring it to the cardboard that has passed, thus achieving the coating effect.

[0003] Because the glue is applied between two rollers, excess glue will flow out from both sides during the application process. This overflowing glue can be collected through a bucket to reduce waste. However, traditional methods often lack an effective mechanism to remove excess glue from the rollers, leading to inconvenience and additional maintenance costs in the long run. Since the amount of glue used cannot be effectively controlled and recycled, this method inevitably wastes raw materials and increases production costs. As the usage time increases, the accumulated glue will increase the difficulty of equipment maintenance. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gluing device for cigarette box cardboard, comprising two machine housings, a gluing roller, an auxiliary roller, and multiple guide rollers. The machine housings are connected to the gluing roller and guide rollers via a transmission connection. The gluing roller and the auxiliary roller are in contact to form a glue seam area. The guide rollers are located below the gluing roller. A frame is fixed between the two machine housings. A glue guiding device, two scrapers, two glue guiding shells, and two support plates are installed on the frame.

[0005] The adhesive guiding end of the adhesive guiding device is located above the adhesive joint area;

[0006] The two sides of the coating roller and the auxiliary roller extend into the corresponding glue guide shell. The scraper is located above the glue guide shell. One end of the scraper has a convex plate and is inclined to be in contact with the two sides of the coating roller and the auxiliary roller.

[0007] The support plate has a notch, in which a protruding cylinder is engaged. The bottom of the protruding cylinder can be connected to an external heating cylinder through a tube. The glue inlet of the protruding cylinder is connected to the glue outlet of the glue guide shell.

[0008] Furthermore, the inner side of the adhesive guide shell is formed with a slope extending to the adhesive outlet.

[0009] Furthermore, the two adhesive guide shells have an open side on opposite sides, and the inner bottom wall is in contact with the roller body of the adhesive coating roller and the auxiliary roller, and the open side is located in the adhesive seam area and forms an arc plate.

[0010] Furthermore, an opening is formed on one side of the adhesive guide shell, and a side plate that is in contact with the side of the adhesive coating roller is fixed to the side of the adhesive guide shell at the opening by screws.

[0011] Furthermore, a back frame is fixed between the two chassis, and a connecting plate is fixed to the bottom of the back frame by a locking plate. A guide wheel is installed at the front end of the connecting plate, and multiple through holes are opened on the plate surface, in which steel balls are placed.

[0012] Furthermore, each of the two machine boxes has a side groove on one side facing each other. An inner block that is slidably connected to the side groove and rotatably connected to the auxiliary roller is rotatably connected to the inner block and threaded rod that passes through the machine box. A handle is fixed to the outside of the threaded rod, and a threaded cylinder that is threadedly connected to the top of the machine box and fixed to the top of the machine box is threadedly connected to it. A spring is sleeved on the outside of the threaded rod.

[0013] Furthermore, the adhesive guiding device includes an adhesive box fixed on the frame, a temperature sensor and a heating rod extending into the box are installed on the top of the adhesive box, and an adhesive inlet pipe connected to an external heating cylinder is installed.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The gluing device for this cigarette box cardboard uses a glue guiding device to direct glue into the glue seam area. The machine housing drives the glue-applying roller and guide roller to rotate. The conveyor belt, in conjunction with the guide roller, transports the cardboard to the area below the glue-applying roller. The glue-applying roller, in conjunction with an auxiliary roller, applies glue to the cardboard. Then, a scraper guides and scrapes off excess glue into the glue guide shell, and a convex cylinder, in conjunction with an external tube, guides it into a heating cylinder for collection. This allows for the scraping off of glue that overflows and adheres to the sides of the roller during operation, thus avoiding waste of raw materials and increasing service life and maintenance costs.

[0020] 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.

[0021] Please see Figure 1-3 This embodiment of a gluing device for cigarette box cardboard includes two housings 1 and two sets of conveyor tables connected to the housings 1. A transmission device is installed in one of the housings 1. A gluing roller 2, an auxiliary roller 3 and a plurality of guide rollers 4 are rotatably connected between the two housings 1. A frame 10 is fixed thereon. The transmission device is connected to the gluing roller 2 and the auxiliary roller 3. The gluing roller 2 and the auxiliary roller 3 are in contact to form a glue seam area. A glue guiding device connected to an external circulating heating cylinder is installed on the frame 1. A guide scraper assembly is installed on both sides of the roller body of the gluing roller 2 and the auxiliary roller 3. The glue outlet of the guide scraper assembly is connected to the circulating heating cylinder. An auxiliary limiting assembly is installed between the two housings 1 and is in contact with the corresponding conveyor table.

[0022] In the above structure, the cardboard is conveyed by the inlet conveyor. During the conveying process, it passes through the auxiliary limiting component, which can press down and limit the cardboard to improve the stability of the cardboard during the conveying process until it is conveyed to the guide roller. Then, in conjunction with the transmission device, the glue coating roller is driven to rotate. Then, the circulating heating cylinder conveys the glue in the cylinder to the glue seam area through the glue guiding device. The cardboard will then complete the glue coating operation by the cooperation of the glue coating roller and the guide roller.

[0023] During the glue application process, the glue will move to both sides of the glue seam area. Therefore, under the action of the guide scraper component, the glue can be guided to the external circulating heating cylinder to prevent glue from splashing onto the equipment and being difficult to clean. At the same time, it can also scrape off the glue on the side of the roller, preventing it from being difficult to clean after a long time and effectively saving raw materials.

[0024] The adhesive guiding device includes an adhesive box 11 fixed to the top of the frame 10. A short plate is fixed to the inside of the adhesive box 11, and a temperature sensor 12, a heating rod 13, and an adhesive inlet tube 14 extending into the box are installed on the top. The adhesive inlet tube 14 is connected to an external circulating heating cylinder through a tube body. Four adhesive guiding tubes are installed at the bottom of the adhesive box 11, all above the adhesive joint area. When the external circulating heating cylinder introduces adhesive into the adhesive box through the adhesive inlet tube, the temperature sensor detects the temperature of the adhesive. When the temperature is low, the heating rod can heat the adhesive in the adhesive box, or it can continuously heat it to a certain temperature, allowing the adhesive to flow smoothly out through the adhesive guiding tube.

[0025] like Figure 1 and 2 Each of the two machine housings 1 has a side groove 5 on one side facing each other. An inner block 6, rotatably connected to the auxiliary roller 3, is slidably connected to the side groove 5. A threaded rod 25, passing through the machine housing 1, is rotatably connected to the top of the inner block 6. A spring 9, located in the side groove 5, is sleeved on the outside of the threaded rod 25, and a threaded cylinder 7, fixed to the top of the corresponding machine housing 1, is also threadedly connected to the outside of the threaded rod 25. A handle 8, located above the threaded cylinder 7, is also fixed to the outside of the threaded rod 25. Before applying glue to the cardboard, the threaded rod can be rotated by the handle, causing it to rise and fall on the threaded cylinder. This moves the auxiliary roller up and down, allowing adjustment of the auxiliary roller according to actual needs. The spring also acts as a buffer during the rising and falling process.

[0026] like Figure 2 The auxiliary limiting component includes a back frame 20 fixed between two housings 1. A connecting plate 21 is fixed to the bottom of the back frame 20 via a locking plate 24. The tail end of the connecting plate 21 faces the guide roller 4, and the other end extends to the conveyor belt of the corresponding conveyor table. The connecting plate 21 has multiple equally spaced through holes, each containing a steel ball 22. A guide wheel 23 is installed at the head end of the connecting plate 21, and both the guide wheel 23 and the steel ball 22 are in contact with the conveyor belt. When the conveyor table transports the cardboard, the cardboard passes under the connecting plate. Upon passing, it is first pressed down by the guide wheel, and as it continues forward, it is further pressed down by the total weight of the steel balls. This ensures the cardboard is tightly pressed against the conveyor belt, improving transport stability, until it is transported under the glue coating roller in conjunction with the guide roller.

[0027] like Figure 3The guide scraper assembly includes two sets of scrapers 15 and a guide shell 16 fixed on the frame 10. The scraper 15 is located above the corresponding guide shell 16. The scraper 15 is arc-shaped and has a convex plate at one end. The convex plate is inclined under the arc shape of the scraper 15 and is in contact with the left and right sides of the roller body of the coating roller 2 and the auxiliary roller 3. The opposite side of the guide shell 16 is open. The auxiliary roller 3 is installed at a higher height than the coating roller 2, and the roller bodies of the coating roller 2 and the auxiliary roller 3 extend into the interior of the guide shell 16 to fit with the guide shell 16. Therefore, the bottom of the guide shell 16 is inclined. The guide shell 16 has an arc-shaped plate located below the coating roller and the auxiliary roller, which is the glue seam area.

[0028] Because the guide shell is compatible with the coating roller and auxiliary roller, its bottom is inclined. When the glue is introduced between the two rollers, the excess glue will flow to both sides. Therefore, under the action of the scraper, the glue overflowing from the two rollers can be placed and adhered to both sides of the roller. The scraped glue will also fall into the guide shell. The internal inclination can effectively guide the glue to the outlet. At the same time, the cooperation between the roller and the arc plate can play a role in blocking the glue and preventing the glue from overflowing and smoothly guiding it to the outlet.

[0029] Meanwhile, an opening is formed on the front end of the glue guide shell 16, and a side plate 17 that is attached to the side of the glue coating roller 2 is fixed to the opening of the glue guide shell 16 by screws. The aforementioned scraper can guide and scrape the glue overflowing from the glue seam area into the glue guide shell, preventing it from adhering to the roller body. At the same time, because the glue guide shell is inclined, when the scraper passes once, the glue will flow down the slope to the side of the glue coating roller. Therefore, under the action of the side plate, the side of the glue coating roller can be scraped again, improving the scraping effect.

[0030] In addition, each of the two chassis 1 is fixed with a support plate 18 facing each other. An opening is provided on one side of each support plate 18, and a protruding cylinder 19 is engaged within the opening. The inner side of the protruding cylinder 19 is sloped, and its inlet is aligned with the outlet of the glue guide shell 16. The bottom of the protruding cylinder 19 is connected to an external circulating heating cylinder via a pipe. Glue flows into the protruding cylinder through the guide shell, and then into the circulating heating cylinder through the protruding cylinder and pipe. This effectively prevents glue from overflowing or splashing onto other equipment during collection, and also facilitates the removal, replacement, or cleaning of the protruding cylinder.

[0031] The working principle of the above embodiments is as follows:

[0032] The conveyor belt feeds the cardboard forward. The transmission mechanism inside the machine drives the coating roller and guide roller to rotate. The coating roller, in turn, drives the auxiliary roller to rotate. The cardboard passes under the guide rollers and steel balls in sequence. The guide rollers and steel balls, by their own weight, press the cardboard close to the conveyor belt until it reaches the guide roller. The guide roller, in conjunction with the coating roller, completes the coating process. Simultaneously, an external circulating heating cylinder collects the glue and introduces it through the glue inlet pipe. A temperature sensor controls the temperature, and a heating rod heats the glue to prevent curing. The glue then flows through the glue inlet pipe onto the coating roller. Between the auxiliary roller and the coating roller, the auxiliary roller works with the coating roller to attach an appropriate amount of glue to the coating roller body, so that the coating operation is completed when the board passes under the coating roller. Excess glue will flow out to both sides, and the scraper will guide the glue into the glue guide shell. The scraper will also scrape the glue on both sides of the roller body. The glue will collect at the glue outlet of the glue guide shell and will also adhere to the coating roller. Therefore, under the action of the side plate, the coating roller can be scraped again to improve the cleaning effect. Then the glue will flow back to the external circulating heating cylinder for collection through the convex cylinder and the tube.
