[0002] Corrugated cardboard is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into two categories: single-wall corrugated cardboard and double-wall corrugated cardboard. It has the advantages of low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. In the process of corrugated cardboard processing, a corrugated cardboard gluing device is used to apply glue to both sides of the corrugated paper base paper so as to bond the corrugated paper base paper and flat paper together to form a complete corrugated cardboard.

[0003] The existing equipment cannot effectively control the amount of adhesive dispensed during the application process, resulting in either too much or too little adhesive being dispensed, leading to uneven application. Furthermore, the existing equipment cannot adjust the amount of adhesive dispensed according to specific working conditions, thus limiting its application.

[0004] Therefore, those skilled in the art have provided a corrugated cardboard layering and gluing device to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] like Figure 1-6 As shown, this application discloses a corrugated cardboard layer coating equipment, including a workbench 2. A feeding roller 11 is rotatably connected inside the workbench 2. The feeding roller 11 is used to transport materials. The upper end of the feeding roller 11 is 5 mm higher than the upper end of the workbench 2. Support plates 4 are fixedly connected to both sides of the upper end of the workbench 2. A motor 3 is fixedly connected to the right side of the right support plate 4. The motor 3 is a driving device. In the prior art, a coating roller 8 is fixedly connected to the output end of the motor 3. The motor 3 drives the coating roller 8 to rotate to realize the coating work. A glue dispensing mechanism is provided at the upper end of the support plate 4.

[0025] The glue dispensing mechanism includes a liquid storage tank 1 fixedly connected to the upper end of the support plate 4, and a rotating roller 12 rotatably connected to the lower end of the liquid storage tank 1. Rectangular grooves 13 are evenly opened on the outer side of the rotating roller 12. A liquid guide block 10 is fixedly connected to the inner wall of the support plate 4. The upper end of the liquid guide block 10 matches the outer side of the rotating roller 12, and the lower end is attached to the upper end of the glue coating roller 8 to realize the guiding work of the glue liquid. The left side of the rotating roller 12 and the left side of the glue coating roller 8 are driven by a belt 7.

[0026] During operation, the motor 3 drives the coating roller 8 to rotate. At this time, the coating roller 8 drives the rotating roller 12 to rotate synchronously via the belt 7. When the rotating roller 12 rotates, the rectangular groove 13 rotates. When the rectangular groove 13 rotates and enters the liquid storage tank 1, the glue enters the rectangular groove 13. When the rectangular groove 13 is at the lower end, the glue is discharged. In this way, the glue can be discharged continuously, stably and evenly. At the same time, the rotation speed of the coating roller 8 can be changed according to the speed of the paperboard conveying, and thus the rotation speed of the rotating roller 12 can be changed accordingly to match the glue dispensing speed. When the operation stops, the rotating roller 12 stops rotating, which can stop the glue dispensing in time, thus improving the glue dispensing effect when the device is used.

[0027] like Figure 4 and Figure 6 As shown, a movable plate 14 is slidably connected inside the rotating roller 12. The movable plate 14 is located inside the rectangular groove 13. A threaded rod 15 is rotatably connected inside the rotating roller 12. A push block 9 is threadedly connected to the rod wall of the threaded rod 15. The middle position of the movable plate 14 is inclined.

[0028] Rotating the threaded rod 15 causes the push block 9 to rotate, and the push block 9 and the moving plate 14 are in contact and have friction, so they will not rotate. When the push block 9 moves, the moving plate 14 moves, thereby changing the volume inside the rectangular groove 13. This improves the applicability of the device during operation.

[0029] like Figure 5 As shown, the left side of the rotating roller 12 is evenly provided with a sliding groove 16, and a slider 17 is slidably connected inside the sliding groove 16. The right side of the slider 17 is fixedly connected to the moving plate 14, and a spring 18 is fixedly connected to one side of the slider 17. The slider 17 moves inside the sliding groove 16, and at the same time, the spring 18 exerts a certain pushing force on the slider 17. This is beneficial for the resetting of the moving plate 14 during operation.

[0030] like Figure 1 As shown, a lead screw 5 is provided at the rear end of the worktable 2. A limiting plate 6 is rotatably connected to one side of the lead screw 5. By rotating the lead screw 5, the limiting plate 6 can be moved, thereby limiting the movement of the cardboard and preventing the cardboard from tilting and affecting the coating effect of the cardboard.

[0031] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] The implementation principle of a corrugated cardboard layer coating equipment in this application is as follows:

[0034] During operation, motor 3 drives the coating roller 8 to rotate. Simultaneously, the coating roller 8, via belt 7, drives the rotating roller 12 to rotate synchronously. The rotation of the rotating roller 12 causes the rectangular groove 13 to rotate. As the rectangular groove 13 rotates and enters the liquid storage tank 1, the adhesive enters it. When the rectangular groove 13 reaches its lower end, the adhesive is discharged. This ensures continuous, stable, and uniform adhesive discharge. Furthermore, the rotation speed of the coating roller 8 can be adjusted according to the speed of the cardboard conveyor, thereby correspondingly changing the rotation speed of the rotating roller 12 to match the adhesive dispensing speed. When the device stops working, the rotating roller 12 stops rotating, which can stop the glue dispensing in time and improve the glue dispensing effect when the device is used. By rotating the threaded rod 15, the push block 9 rotates. The push block 9 and the moving plate 14 are in contact and there is friction, so they will not rotate. When the push block 9 moves, the moving plate 14 moves, thereby changing the volume inside the rectangular groove 13. This improves the applicability of the device during operation. The slider 17 moves inside the groove 16, and the spring 18 exerts a certain pushing force on the slider 17. This is conducive to the reset of the moving plate 14 during operation.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
