Description

Technical Field

[0001] The utility model relates to a pressing device, in particular to a pressing device for a paper box, and belongs to the technical field of paper box production. Background Art

[0002] When cartons are produced, in order to make the carton layers bonded and connected, an adhesive layer is usually applied on the carton, and then the cardboard is attached to the adhesive layer for connection, so as to make the carton tighter, thereby improving the carton's compressive strength, bursting strength and puncture resistance, and thus better protect the items in the package.

[0003] At present, when laminating cartons, the cartons are usually placed between two sets of relatively set conveyor belts for lamination. Since the thickness of different types of cartons may be inconsistent, the conveyor belts rolling against each other may not provide sufficient pressure, resulting in poor lamination effect of the cartons, and the expected sealing and firmness cannot be achieved. In addition, when laminating through the conveyor belt, the adhesive parts cannot be pressed in a targeted manner, which may cause looseness and other phenomena.

[0004] Therefore, there is an urgent need to improve the pressing device for paper boxes to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] like Figure 1-Figure 4 As shown, the present embodiment provides a laminating device for cartons, a conveying and laminating assembly, a pressing wheel 4 and a pressure control assembly, wherein the conveying and laminating assembly comprises two machine bodies 1, an upper conveyor belt 2 and a lower conveyor belt 21 rotating in the opposite direction to the upper conveyor belt 2, wherein the upper conveyor belt 2 and the lower conveyor belt 21 are respectively rotatably connected to the two machine bodies 1, and through the reverse rotation between the upper conveyor belt 2 and the lower conveyor belt 21, when the carton is placed between the two, the carton can be conveyed, the two machine bodies 1 are connected by a telescopic member 3, and the telescopic member 3 can be a structure such as an electric telescopic rod or a hydraulic telescopic rod, the circumferential outer wall of the pressing wheel 4 is tangent to the lower inner wall of the upper conveyor belt 2, and is used for targeted laminating of the adhesive portion, and the pressure control assembly comprises a pressure sensor 5 and a controller 6 electrically connected to the pressure sensor 5, and the controller 6 is used for receiving a pressure signal of the pressure sensor 5 to control the movement of the telescopic member 3, and is used for adjusting the spacing between the upper conveyor belt 2 and the lower conveyor belt 21, so as to be suitable for laminating cartons of different thicknesses;

[0023] The control circuit of the controller 6 can be implemented by programming by those skilled in the art, which is common knowledge in the art. It is only used without modification, so the control method and circuit connection will not be described in detail.

[0024] Further, such as Figure 3As shown, a fixed groove 7 is provided on the inner wall at the bottom of the input end of the machine body 1 located at the top, and a connecting frame 8 is slidably connected inside the fixed groove 7, and a pressure roller 9 is rotatably connected inside the connecting frame 8. The upper end of the connecting frame 8 is connected to a spring 10, and the pressure sensor 5 is connected to the upper end of the spring 10. Before the pressing work, the carton is first placed between the pressure roller 9 and the lower conveyor belt 21. At this time, the pressure roller 9 will be driven by the resistance force of the carton to drive the spring 10 to move upward. When the spring 10 drives the pressure sensor 5 to contact the top wall of the fixed groove 7, a pressure signal will be generated and transmitted to the controller 6. The controller 6 will retract the telescopic member 3 according to whether the pressure signal value is within the pressure threshold, thereby adjusting the spacing between the upper conveyor belt 2 and the lower conveyor belt 21 to provide balanced pressure for cartons of different thicknesses, thereby avoiding situations such as insufficient pressure due to thin cartons or excessive pressure due to thick cartons.

[0025] Further, such as Figure 4 As shown, a transmission rod 11 is connected to the inner wall of the upper body 1, and the pressure wheel 4 is movably connected to the transmission rod 11, and a hollow push rod 12 is threadedly connected to the upper body 1, and one end of the hollow push rod 12 extending to the inside of the body 1 is rotatably connected to a connecting wheel 13, and the connecting wheel 13 is rotatably connected to the pressure wheel 4. The connecting wheel 13 is pushed by rotating the hollow push rod 12, so that the connecting wheel 13 drives the pressure wheel 4 to move to the top of the bonding point of the carton, and the bonding point of the carton is pressed in a targeted manner, thereby enhancing the bonding effect and making the bonding point tighter.

[0026] Further, such as Figure 4 As shown, a rotating ring 14 is movably connected to the hollow push rod 12, an indicator needle 15 is connected below the rotating ring 14, and a scale 16 is connected to the outer wall of the body 1. When the hollow push rod 12 rotates, the distance extended to the inside of the body 1 will drive the rotating ring 14 and the indicator needle 15 to move the same distance in the direction of the body 1. By measuring the distance between the gluing point of the carton and the inner wall of the body 1 in advance, the movement distance of the pressing wheel 4 driven by the hollow push rod 12 can be determined according to the value of the scale 16 pointed by the indicator needle 15, so that the pressing wheel 4 can be pressed above the gluing point of the carton more accurately.

[0027] Further, such as Figure 4 As shown, two limit rings 17 are provided on the hollow push rod 12. The two limit rings 17 are located on both sides of the rotating ring 14 and are used to limit the axial displacement of the rotating ring 14 along the hollow push rod 12, so that the rotating ring 14 will not cause the indicator needle 15 to move randomly, and under the action of its own gravity, the indicator needle 15 will always point downward to the scale 16.

[0028] Further, such as Figure 2 As shown, there are multiple groups of pressing wheels 4. When there are multiple groups of adhesive spots on the carton, the positions of different pressing wheels 4 can be adjusted to perform pressing work on different adhesive spots.

[0029] like Figure 1-Figure 4 As shown, the principle of the laminating device for cartons provided in this embodiment is as follows: when laminating the cartons, first determine the gluing position on the cartons, and use the value on the scale line pointed by the indicator needle 15 as a reference, then drive the rotating wheel to move by rotating the hollow push rod 12, and use the value on the scale line pointed by the indicator needle 15 as a reference, so as to move the pressing wheel 4 to the top of the gluing position that needs to be pressed, and perform targeted pressing on the gluing position, so as to achieve a better gluing effect, and then put the carton between the pressing roller 9 and the lower conveyor belt 21, the pressing roller 9 will drive the connecting frame 8 to move upward, and drive the pressure sensor 5 to contact the inner wall at the top of the fixed groove 7, the pressure sensor 5 will transmit the pressure signal to the controller 6, the controller 6 controls the telescopic member 3 to move downward, at this time, the body 1 located above drives the upper conveyor belt 2 and the pressing roller 9 to move downward synchronously, when the pressure sensor 5 detects that the pressure value is within the specified threshold, the pressure signal is transmitted to the controller 6, the controller 6 controls the telescopic member 3 to stop, so as to be suitable for laminating cartons of different thicknesses.
