[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] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0022] In traditional cardboard box production bending and gluing equipment, the cardboard to be bent needs to be manually placed above the cardboard conveyor assembly by workers. This repetitive work is labor-intensive. At the same time, manual operation is subject to human error, making it impossible to add cardboard at a stable and uniform speed, frequently disrupting the operating rhythm of the equipment, resulting in a significant decline in the working efficiency of the bending and gluing equipment.

[0023] In view of this, the present invention provides a cardboard box production bending and gluing device. The bending mechanism, in conjunction with an electric push rod, a straight plate, and rollers, bends cardboard into the shape of a cardboard box. The feeding mechanism, in conjunction with an inclined plate, feeds multiple cardboards into the bending mechanism at a uniform speed. The cardboard does not need to be repeatedly added to the bending mechanism by the workers, reducing the labor intensity of the workers. At the same time, the feeding mechanism can add cardboard into the bending mechanism at a uniform speed. The cardboard box production bending and gluing device can operate stably and will not affect the working efficiency of the bending and gluing device.

[0024] Example 1: By Figure 1 , 2 As can be seen from points 3, 4, 5, and 6, a cardboard box production bending and bonding device includes a device housing 1. An outer frame 4 is fixedly connected to one side of the outer wall of the device housing 1, and an inclined plate 3 is fixedly connected to the inner wall of the device housing 1. A bending mechanism 9 is provided on the inner wall of the device housing 1 near the outer frame 4, and a feeding mechanism 2 is provided on the inner wall of the device housing 1 away from the outer frame 4. The feeding mechanism 2 includes: a first spring 21, fixedly connected to the inner wall of the device housing 1 away from the outer frame 4; a slider 22, fixedly connected to the bottom of the first spring 21 and slidably engaged with the inner wall of the device housing 1 away from the outer frame 4; a first rotating roller 23, rotatably connected to the lower part of the slider 22 via a bearing; and a second rotating roller 25, which is attached to the outer wall of the first rotating roller 23. The first electric push rod 27 is fixedly connected to the lower side of the outer wall of the device housing 1 away from the outer frame 4 via a bearing; the push plate 26 is fixedly connected to the output end of the first electric push rod 27 and fits against the inner wall of the device housing 1 away from the outer frame 4; wherein, when the first electric push rod 27 drives the push plate 26 to work, it pushes the cardboard stacked inside the housing 1 away from the outer frame 4 outward. When the cardboard enters between the two rollers, the servo motor 24 drives the second roller 25 to rotate, and cooperates with the first roller 23 to complete the automatic feeding of the cardboard.

[0025] In the specific implementation process, it is worth noting that the pull rod is reinforced between the outer frame 4 and the device housing 1. The models of the servo motor 24 and the first electric push rod 27 are not limited, as long as they meet the usage requirements. The first electric push rod 27 drives the push plate 26 to move, pushing the cardboard at the bottom to the space between the first roller 23 and the second roller 25. The servo motor 24 drives the second roller 25 to rotate, which, together with the first roller 23, pushes the cardboard outward. The inclined plate 3 limits the pushed cardboard to ensure that the cardboard can fall above the bending mechanism 9.

[0026] Specifically, when using this cardboard production bending and gluing device, multiple cardboard pieces with pre-crimped designs are placed inside the outer casing 1 of the device on the side away from the outer frame 4. When the cardboard needs to be fed, the operator controls the first electric push rod 27 and the servo motor 24 to work simultaneously via the external control panel. The first electric push rod 27 drives the push plate 26 to move, and the push plate 26 pushes the cardboard at the bottom outward. The first spring 21 presses the first rotating roller 23 against the second rotating roller 25, and the cardboard enters between the first rotating roller 23 and the second rotating roller 25. The servo motor 24 drives the second rotating roller 25 to rotate, cooperating with the first rotating roller 23 to push the cardboard outward, thus completing the feeding of the cardboard.

[0027] Example 2: From Figure 1 , 2 As can be seen from section 3, the bending mechanism 9 includes: a first guide rod 91, which is fixedly connected to the inner wall of the device housing 1; a second guide rod 92, which is fixedly connected to the inner wall of the device housing 1; and a conveyor belt 93, which is installed on the inner wall of the device housing 1. When the conveyor belt 93 is working, it drives the cardboard to move, and the first guide rod 91 cooperates with the second guide rod 92 to bend the cardboard along the indentation.

[0028] In the specific implementation process, it is worth noting that the conveyor belt 93 includes at least one active roller, at least one driven roller, a drive motor, a belt and a tensioning pulley. The belt is sleeved on the outer wall of the active roller and the driven roller. Under the action of the drive motor, the active roller drives the driven roller to rotate through the belt to realize the conveying of materials. The device housing supports and installs the conveyor belt 93. One end of each of the two guide rods is lower than the top of the conveyor belt 93.

[0029] Furthermore, two third electric push rods 7 are fixedly connected to the inner wall of the device housing 1 near the outer frame 4. A straight plate 8 is fixedly connected to the bottom of the two third electric push rods 7. Multiple rollers 10 are rotatably connected to the inner wall of the straight plate 8 through bearings. The outer walls of the multiple rollers 10 are in contact with the outer wall of the conveyor belt 93.

[0030] In the specific implementation process, it is worth noting that the model of the third electric push rod 7 is not limited, as long as it meets the usage requirements. The third electric push rod 7 uses the straight plate 8 to attach multiple rollers 10 to the top of the conveyor belt 93.

[0031] Specifically, the operator controls the third electric push rod 7, which drives multiple rollers 10 to adhere to the conveyor belt 93 via the straight plate 8. The cardboard is restricted by the inclined plate 3 and moves towards the conveyor belt 93. The cardboard enters between the rollers 10 and the conveyor belt 93. The conveyor belt 93 moves the cardboard through friction. Since the shape of the first guide rod 91 and the second guide rod 92 gradually converges from the outside to the inside, and one end of the first guide rod 91 and the second guide rod 92 is lower than the top of the conveyor belt 93, and the other end of the first guide rod 91 and the second guide rod 92... Adjacent to the top of the conveyor belt 93, ensuring that the cardboard can be bent 180 degrees, when the conveyor belt 93 moves the cardboard above the first guide rod 91 and the second guide rod 92, the first guide rod 91 and the second guide rod 92 lift the outer side of the cardboard and restrict the cardboard from bending inward from the indentation. As the cardboard continues to move, the first guide rod 91 and the second guide rod 92 continue to bend the cardboard inward, completing the bending operation of the cardboard. Since the operating height of the second guide rod 92 is slightly higher than that of the first guide rod 91, the cardboard bent at the second guide rod 92 is above the first guide rod 91.

[0032] Example 3: From Figure 1 , 2As shown in section 3, the inner wall of the device housing 1 is provided with a glue-applying mechanism 6. The glue-applying mechanism 6 includes: a glue storage cylinder 61, which is inserted into the inner wall of the device housing 1 on the side away from the outer frame 4; a glue-applying roller 62, which is rotatably connected to the inner wall of the glue storage cylinder 61 through a bearing; two connecting plates 64, both of which are fixedly connected to the outer wall of the glue storage cylinder 61; and two second electric push rods 63, which are respectively fixedly connected to the top of the two connecting plates 64 and are fixedly connected to the inner wall of the device housing 1 on the side away from the outer frame 4. The two second electric push rods 63 drive the glue storage cylinder 61 to a designated position through the two connecting plates 64. The glue storage cylinder 61 drives the glue-applying roller 62 below to adhere to the outer wall of the cardboard. When the cardboard moves, glue is applied to the outer wall of the cardboard.

[0033] In the specific implementation process, it is worth noting that the model of the second electric push rod 63 is not limited, as long as it meets the usage requirements. It can add glue from the top of the glue storage cylinder 61. When the second electric push rod 63 is working, it drives the glue coating roller 62 below the glue storage cylinder 61 to move through the connecting plate 64, so that the glue coating roller 62 is in contact with the outer wall of the cardboard.

[0034] Specifically, based on the above embodiment one, the staff controls the second electric push rod 63 to work through the external control panel. The second electric push rod 63 drives the glue storage cylinder 61 to move through the connecting plate 64. The glue storage cylinder 61 drives the lower glue coating roller 62 to move to the designated position. When the cardboard moves from the top of the conveyor belt 93 to below the glue coating roller 62, the cardboard rubs against the glue coating roller 62 to rotate, and glue is applied to the top of the cardboard.

[0035] Example 4: From Figure 1 , 2 As shown in section 4, a drying mechanism 5 is provided inside the outer frame 4. The drying mechanism 5 includes: a hot air blower 51, which is fixedly connected to the inner wall of the outer frame 4 and extends to the outside of the outer frame 4 at one end; an air supply pipe 52, which is connected to the output end of the hot air blower 51; multiple exhaust hoods 53, which are all fixedly connected to the bottom of the air supply pipe 52 and communicate with the inner wall of the air supply pipe 52; a horizontal plate 54, which is fixedly connected to the outer wall of the multiple exhaust hoods 53; and multiple second springs 55, which are all fixedly connected to the horizontal plate 54. The top of the frame 4 is fixedly connected to the inner wall of the outer frame 4; multiple extrusion rollers 56 are provided and fixedly connected to the bottom of the horizontal plate 54; conveying rollers 57 are installed on the inner wall of the outer frame 4; wherein, after the carton is glued, multiple second springs 55 in a compressed state push multiple extrusion rollers 56 to move downward, and the extrusion rollers 56 cooperate with the conveying rollers 57 to press the glued carton, while the hot air blower 51 blows hot air out from the exhaust hood 53 through the air supply pipe 52 to dry the glued part of the carton;

[0036] In the specific implementation process, it is worth noting that the top of the multiple exhaust hoods 53 are all telescopic tube structures, which can keep the air supply pipe 52 and the exhaust hood 53 in a continuous state when the horizontal plate 54 moves the exhaust hood 53. The conveying roller 57 includes at least one active roller, multiple driven rollers, a drive motor, a belt and a tensioning pulley. The belt is sleeved on the outer wall of the active roller and the driven roller. Under the action of the drive motor, the active roller drives the driven roller to rotate through the belt to realize the conveying of materials. The outer frame 4 supports and installs the conveying roller 57. The model of the hot air blower 51 is not limited, as long as it meets the usage requirements. The second spring 55 pushes the multiple extrusion rollers 56 to move downward through the horizontal plate 54. The extrusion rollers 56 press the cardboard against the conveying roller 57. When the hot air blower 51 is working, it discharges hot air from the exhaust hood 53 to the outside through the air supply pipe 52.

[0037] Specifically, based on the above embodiment 1, after the cardboard is discharged from the device housing 1, multiple second springs 55 in a compressed state push the extrusion roller 56 to adhere to the conveying roller 57 through the horizontal plate 54. The cardboard enters between the extrusion roller 56 and the conveying roller 57. The extrusion roller 56 cooperates with the conveying roller 57 to press the bonded cardboard tightly. At the same time, the operator controls the hot air blower 51 to work through the external control panel. The hot air blower 51 discharges hot air from the exhaust hood 53 through the air supply pipe 52, and the hot air dries the bonded cardboard.

[0038] 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.
