Description

A cardboard coating device Technical Field

[0001] This utility model belongs to the field of adhesive coating technology, specifically a cardboard adhesive coating device. Background Technology

[0002] Cardboard is a thick, rigid sheet material made from multiple layers of paper or pulp through processes such as pressing and bonding. Common types include corrugated cardboard and grey-backed white cardboard, which are widely used in packaging, construction, and handicrafts. Its compact structure provides good compression resistance and cushioning, effectively protecting the contents. During processing, cardboard requires gluing to bond multiple layers of cardboard or other materials (such as plastic film) to improve overall structural strength and durability. However, traditional cardboard gluing equipment mostly applies glue to the upper surface of the conveying cardboard. This method is prone to glue dripping and uneven application, and it cannot handle cardboard of different widths, resulting in excessive glue on the gluing roller and wastage. Therefore, improvements are needed to address these issues. Summary of the Invention

[0003] To achieve the above objectives, this utility model provides the following technical solution: a cardboard coating device, comprising a main board, a glue groove on the top of the main board, a coating roller installed inside the glue groove, a horizontal square through hole at the axis of the coating roller, a square drive shaft rotatably mounted inside the glue groove, the coating roller being mounted on the surface of the square drive shaft through the horizontal square through hole, and symmetrically fixedly mounted auxiliary plates on both sides of the main board, each auxiliary plate having a mounting groove on its top, a conveyor shaft rotatably mounted at equal intervals inside the two mounting grooves, and conveyor wheels fixedly mounted at equal intervals on the surface of the conveyor shafts, the top of the conveyor wheels being flush with the top of the coating roller.

[0004] Preferably, a bearing is installed at one end of the coating roller, the bearing coincides with the axis of the horizontal square through hole, and the square drive shaft passes through the bearing. The inner ring of the bearing is fixedly connected to one end of the coating roller, and a connecting plate is fixedly installed on the outer ring of the bearing. A threaded shaft is rotatably installed on one side of the top of the main board of the device, and one side of the connecting plate is threadedly connected to the threaded shaft. A motor A connected to one end of the threaded shaft is installed on the top of the main board of the device, so that the coating roller can adjust the width for paperboards of different widths.

[0005] Preferably, a motor B connected to one end of a square drive shaft is mounted on one end of the main board of the device, and a bevel gear A fixedly connected to the other end of the square drive shaft is mounted on the other end of the main board of the device.

[0006] Preferably, a worm gear is rotatably mounted between one side of the two device sub-plates, and a bevel gear B that meshes with bevel gear A is fixedly mounted in the middle of the worm gear. One end of the conveying shaft inside the two mounting slots extends to the outside of one side of the two device sub-plates and is fixedly mounted with a worm wheel. All the worm wheels are meshed with the worm gear, thereby enabling effective conveying of the cardboard.

[0007] Preferably, the glue tank is a concave arc-shaped groove, and the glue-applying roller is in contact with the bottom of the concave arc-shaped groove. The concave arc-shaped groove ensures that the glue is always in contact with the glue-applying roller without waste, and at the same time, the glue-applying roller will not be unable to pick up glue due to the reduction of glue. The conveying wheel is a flat disc structure. The flat disc structure of the conveying wheel can effectively reduce the amount of glue picked up by the conveying wheel when conveying the cardboard.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This cardboard coating device performs uniform coating on the bottom of the moving cardboard by means of bottom coating. The bottom coating method will not cause glue dripping or uneven coating. At the same time, this cardboard coating device has a horizontally adjustable coating roller, which can effectively coat cardboard of different widths and avoid glue waste, thereby effectively improving the quality of cardboard coating. Furthermore, this cardboard coating device has a simple structural design, is convenient to use, and has stable and reliable adjustment and coating operation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] As shown in Figures 1 to 3, this utility model includes a main device 1. A glue groove 2 is provided on the top of the main device 1. A glue-applying roller 3 is installed inside the glue groove 2. A horizontal square through hole is provided at the axis of the glue-applying roller 3. A square drive shaft 4 is rotatably installed inside the glue groove 2. The glue-applying roller 3 is installed on the surface of the square drive shaft 4 through the horizontal square through hole. Device sub-plates 5 are symmetrically fixedly installed on both sides of the main device 1. A mounting groove 6 is provided on the top of each of the two device sub-plates 5. A conveyor shaft 7 is rotatably installed at equal distances inside the two mounting grooves 6. A conveyor wheel 8 is fixedly installed at equal distances on the surface of the conveyor shaft 7. The top of the conveyor wheel 8 is flush with the top of the glue-applying roller 3.

[0017] The glue tank 2 is a concave arc-shaped groove, and the glue roller 3 is in contact with the bottom of the concave arc-shaped groove. The concave arc-shaped groove ensures that the glue is always in contact with the glue roller 3 without waste. At the same time, the glue roller 3 will not be unable to pick up glue due to the reduction of glue. The conveying wheel 8 is a flat disc structure. The flat disc structure of the conveying wheel 8 can effectively reduce the amount of glue picked up by the conveying wheel 8 on the paperboard when conveying the paperboard.

[0018] A bearing 9 is installed at one end of the coating roller 3. The bearing 9 coincides with the axis of the horizontal square through hole, and the square drive shaft 4 passes through the bearing 9. The inner ring of the bearing 9 is fixedly connected to one end of the coating roller 3. A connecting plate 10 is fixedly installed on the outer ring of the bearing 9. A threaded shaft 11 is rotatably installed on one side of the top of the main board 1. One side of the connecting plate 10 is threadedly connected to the threaded shaft 11. A motor A12 connected to one end of the threaded shaft 11 is installed on the top of the main board 1, so that the coating roller 3 can adjust the width for different widths of cardboard.

[0019] Specifically, by starting the motor A12, the threaded shaft 11 is rotated. The rotation of the threaded shaft 11 causes the connecting plate 10 to move on its surface. The movement of the connecting plate 10, through the bearing 9, pulls the glue-applying roller 3 to move on the surface of the square drive shaft 4, thereby adjusting the length of the glue-applying roller 3 between the two device sub-plates 5, so that the glue-applying roller 3 can adjust the glue-applying width for cardboard of different widths.

[0020] One end of the main board 1 is equipped with a motor B13 connected to one end of a square drive shaft 4, and the other end of the main board 1 is equipped with a bevel gear A14 fixedly connected to the other end of the square drive shaft 4. A worm gear 15 is rotatably mounted between one side of the two auxiliary plates 5. A bevel gear B16, which meshes with the bevel gear A14, is fixedly mounted in the middle of the worm gear 15. One end of the conveying shaft 7 inside the two mounting slots 6 extends to the outside of one side of the two auxiliary plates 5 and is fixedly mounted with a worm wheel 17. All the worm wheels 17 are meshed with the worm gear 15, thereby enabling effective conveying of the cardboard.

[0021] Specifically, starting motor B13 causes square drive shaft 4 to rotate glue coating roller 3 and bevel gear A14. The rotation of bevel gear A14 drives bevel gear B16, which in turn drives worm gear 15. The rotation of worm gear 15 drives all worm wheels 17, causing all conveyor shafts 7 to drive conveyor wheels 8 to rotate in the same direction as glue coating roller 3. The cardboard is then placed on conveyor wheels 8 on one of the device sub-plates 5 for conveying, moving the cardboard toward the rotating glue coating roller 3. The rotating glue coating roller 3 can perform a full glue coating operation on the bottom of the cardboard. Finally, the glued cardboard is conveyed to conveyor wheels 8 on another device sub-plate 5 for further conveying.

[0022] This cardboard coating device applies glue evenly to the bottom of a moving cardboard using a bottom-coating method. This method prevents glue dripping and uneven application. Furthermore, the device features a horizontally adjustable coating roller, enabling effective coating of cardboard of varying widths while avoiding glue waste. This significantly improves the quality of cardboard coating. The device also boasts a simple design, ease of use, and stable and reliable adjustment and coating operations, meeting the performance requirements of cardboard coating processing.
