[0002] Corrugated paper 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 paperboard and double-wall corrugated paperboard. According to the size of the corrugations, it is divided into five types: A, B, C, E, and F. Corrugated paper has been invented and used for more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. More than 80% of corrugated paper can be recycled. Corrugated paper can be used for packaging food or digital products. It is relatively environmentally friendly and widely used.

[0003] Most existing devices have low automation levels and many manual operation steps. Operators need to pay attention to multiple production steps and parameters at the same time, and the operation process is complicated. This not only increases the labor intensity, but also limits the improvement of production efficiency due to the limited speed and accuracy of manual operation. Therefore, an automatic bonding device for the cushioning layer of corrugated cardboard boxes is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an automatic bonding device for the cushioning layer of corrugated cardboard boxes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A work frame is included, with a first conveyor belt rotatably mounted between the inner walls of the work frame. A motor frame is connected to one side of the work frame, and a motor is connected to the top of the motor frame. The output end of the motor extends into the interior of the work frame, and a transmission roller is connected to its surface. A first transmission gear is connected to the surface of the motor on one side of the work frame. A glue-applying assembly is connected to the top of the work frame. A second conveyor belt is rotatably mounted between the inner walls of the work frame on one side of the glue-applying assembly. Two vertical plates are connected to the top of the work frame above the second conveyor belt. Each of the two vertical plates has an opening at its top, and a paper holder is rotatably mounted inside the opening. A damping turntable is rotatably mounted on the side of the vertical plates that are close to each other. A lever is connected to the surface of the damping turntable, and a pressure rod is connected to one end of each of the two levers. A heating box is connected to one side of the work frame, and through slots are provided on both sides of the heating box.

[0006] Preferably, the glue application assembly includes a glue storage tank connected to the top of the work frame. Inside the glue storage tank, a stirring roller and a glue brushing roller are rotatably arranged, and the diameter of the glue brushing roller is longer than that of the stirring roller. One-quarter of the glue brushing roller is exposed outside the bottom of the glue storage tank and is located above the transfer roller. The rotating shaft of the glue brushing roller extends outside the glue storage tank, and a first rotating gear is connected to its surface. The first rotating gear meshes with a first transmission gear.

[0007] Preferably, two sets of upper and lower hot pressing rollers are rotatably arranged inside the heating box, and the upper and lower hot pressing rollers are distributed vertically. The rotating shafts of the upper and lower hot pressing rollers extend outside the heating box and are respectively connected to a second rotating gear and a second transmission gear, and the second rotating gear and the second transmission gear mesh with each other.

[0008] Preferably, the surface of the motor output end is connected to a first pulley on one side of the first transmission gear and on the surface of the lower hot press roller shaft on the right side, and a first transmission belt is sleeved between the two first pulleys. The surface of the lower hot press roller shaft on the right side is connected to a second pulley on one side of the first pulley and on the surface of the lower hot press roller shaft on the left side, and a second transmission belt is sleeved between the two second pulleys.

[0009] Preferably, a lamp holder is connected to the top of the interior of the heating box, and a heating lamp is connected to the interior of the lamp holder.

[0010] Preferably, a temperature control component is connected to the top of the heating box, and a temperature sensor is connected to one side of the temperature control component.

[0011] Preferably, a lower heating roller is connected to one side of the heating box, and the control panel is electrically connected to the heating lamp, temperature control component and motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The motor drives the first conveyor belt through the transmission roller, and at the same time, a series of transmission structures such as the first transmission gear, the first rotating gear, the first pulley, the first transmission belt, the second transmission gear, the second pulley, and the second transmission belt are used to make the glue-applying roller of the glue-applying assembly, the second conveyor belt, and the upper and lower hot pressing rollers in the heating box operate synchronously. This realizes the automated continuous production of the coated paper from glue application to hot pressing, reduces manual operation links, and greatly improves production efficiency.

[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. 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.

[0016] Please see Figures 1-5This utility model provides a technical solution, including a work frame 1. A first conveyor belt 2 is rotatably arranged between the inner walls of the work frame 1 to facilitate the transfer of the corrugated layer to the next process. A motor frame 3 is connected to one side of the work frame 1, and a motor 4 is connected to the top of the motor frame 3. The output end of the motor 4 extends into the interior of the work frame 1, and a transmission roller 41 is connected to its surface. A first transmission gear 5 is connected to the surface of the motor 4 on one side of the work frame 1. A glue application assembly 6 is connected to the top of the work frame 1. A second conveyor belt 7 is rotatably arranged between the inner walls of the work frame 1 on one side of the glue application assembly 6. Two vertical plates 8 are connected to the top of the work frame 1 above the second conveyor belt 7. An opening 9 is opened at the top of each of the two vertical plates 8. A paper holder 10 is rotatably arranged inside the opening 9. A damping turntable 11 is rotatably arranged on the side of the vertical plates 8 that are close to each other. A lever 12 is connected to the surface of the damping turntable 11. A pressure rod 13 is connected to one end of each lever 12. A heating box 14 is connected to one side of the work frame 1. A through groove 15 is opened on both sides of the heating box 14.

[0017] The glue application assembly 6 includes a glue storage tank 61 connected to the top of the work frame 1. Inside the glue storage tank 61, a stirring roller 62 and a glue application roller 63 are rotatably mounted. The diameter of the glue application roller 63 is longer than that of the stirring roller 62. A quarter of the glue application roller 63 is exposed outside the bottom of the glue storage tank 61 and is located above the transfer roller 41. The shaft of the glue application roller 63 extends outside the glue storage tank 61, and a first rotating gear 64 is connected to its surface. The first rotating gear 64 meshes with a first transmission gear 5. Its function is that when the motor 4 starts, it drives the transfer roller 41 and the first transmission gear 5 to rotate synchronously. The first transmission gear 5 then drives the first rotating gear 64 and the glue application roller 63 to rotate. Because a quarter of the glue application roller 63 is exposed outside the bottom of the glue storage tank 61 and is located above the transfer roller 41, when the corrugated layer is conveyed by the transfer roller 41 to the area below the glue application roller 63, the glue application roller 63 will evenly apply glue to the surface of the corrugated layer. Meanwhile, the stirring roller 62 continuously stirs the glue inside the glue storage tank 61 to prevent the glue from settling or solidifying, ensuring a stable coating effect.

[0018] Inside the heating chamber 14, two sets of upper and lower heating rollers 16 and 18 are rotatably arranged, one above the other. The shafts of both rollers extend outside the heating chamber 14 and are connected to a second rotating gear 17 and a second transmission gear 19, respectively. These gears mesh with each other. Their function is to transfer the corrugated layer and the facing paper into the heating chamber 14 after the gluing process. At this time, the upper and lower heating rollers 16 and 18 begin to function. Because the shafts of the upper and lower heating rollers 16 and 18 are connected to the second rotating gear 17 and the second transmission gear 19, respectively, and these two gears mesh with each other, when the upper heating roller 16 rotates, it drives the lower heating roller 18 to rotate synchronously. When the corrugated layer and the facing paper pass between the upper hot pressure roller 16 and the lower hot pressure roller 18, they are subjected to hot pressure, which makes the facing paper adhere tightly to the surface of the corrugated layer, forming the cushioning layer of the corrugated carton.

[0019] First pulleys 20 are connected to both the output surface of motor 4 on one side of the first transmission gear 5 and the shaft surface of the right lower hot press roller 18. A first transmission belt 21 is fitted between the two first pulleys 20. Second pulleys 22 are connected to both the shaft surface of the right lower hot press roller 18 on one side of the first pulleys 20 and the shaft surface of the left lower hot press roller 18. A second transmission belt 23 is fitted between the two second pulleys 22. The function of this is that motor 4 drives the first rotating gear 64 through the first transmission gear 5, thereby driving the glue-applying roller 63 to rotate. At the same time, motor 4 also drives the right lower hot press roller 18 to rotate through the first pulleys 20 and the first transmission belt 21. Since the right lower hot press roller 18 is connected to the left lower hot press roller 18 through the second pulleys 22 and the second transmission belt 23, the left lower hot press roller 18 will also rotate. In this way, the glue-applying roller 63, the second conveyor belt 7, and the upper and lower hot press rollers 16 and 18 in the heating box 14 in the entire device can all operate synchronously.

[0020] A lamp holder 24 is connected to the top of the interior of the heating chamber 14, and a heating lamp 25 is connected inside the lamp holder 24. The main function of the heating lamp 25 is to provide the necessary heat to ensure that the corrugated paper and the facing paper between the upper heating roller 16 and the lower heating roller 18 are fully heated and tightly bonded. The heat generated by the heating lamp 25 is evenly distributed inside the heating chamber 14, providing a stable temperature environment for the hot pressing process.

[0021] A temperature control component 26 is connected to the top of the heating chamber 14, and a temperature sensor 27 is connected to one side of the temperature control component 26. The function of the temperature sensor 27 is to monitor the temperature change inside the heating chamber 14 in real time and feed the data back to the temperature control component 26.

[0022] A lower heating roller 18 is connected to one side of the heating chamber 14, and the control panel 28 is electrically connected to the heating lamp 25, the temperature control component 26, and the motor 4. The control panel 28 serves as the control center of the entire device, enabling remote control of the heating lamp 25, the temperature control component 26, and the motor 4. Operators can input commands through the control panel 28 to adjust the power of the heating lamp 25, set the target temperature of the temperature control component 26, and start or stop the motor 4, greatly improving the automation level of the device and making operation more convenient and efficient.

[0023] Working principle: First, the operator places the corrugated layer on the first conveyor belt 2. The corrugated layer is conveyed to the transfer roller 41 as the first conveyor belt 2 rotates, and then continues forward to below the glue-applying roller 63. Since a quarter of the glue-applying roller 63 is exposed outside the bottom of the glue storage tank 61 and is located above the transfer roller 41, when the corrugated layer is conveyed to below the glue-applying roller 63, the glue-applying roller 63 will evenly apply glue to the surface of the corrugated layer. Simultaneously, the stirring roller 62 continuously stirs the glue inside the glue storage tank 61 to prevent the glue from settling or solidifying. The glued corrugated layer is then conveyed to the second conveyor belt 7 and continues to move forward. At the same time, the operator removes the face paper from the face paper holder 10 and, through the adjustment of the damping turntable 11 and the lever 12, causes the pressure rod 13 to pre-press the face paper onto the glued corrugated layer. The pressed corrugated layer and face paper assembly is then conveyed into the heating chamber 14. Inside the heating chamber 14, the upper heating roller 16 and the lower heating roller 18 begin to function. Since the shafts of the upper heating roller 16 and the lower heating roller 18 are respectively connected to the second rotating gear 17 and the second transmission gear 19, and these two gears mesh with each other, when the upper heating roller 16 rotates, it drives the lower heating roller 18 to rotate synchronously. As the corrugated layer and the facing paper pass between the upper heating roller 16 and the lower heating roller 18, they are subjected to heat and pressure, causing the facing paper to adhere tightly to the surface of the corrugated layer, completing the bonding of the corrugated box's cushioning layer.
