Description

Technical Field

[0001] The invention relates to a finished paper roll packaging device, in particular to a hot pressing device. Background Art

[0002] In the papermaking field, hot pressing devices are common equipment in the packaging system of finished paper rolls. In the packaging system, after the inner head is placed, the radial kraft paper is folded, and the paper roll is packaged, the outer heads need to be pressed on both ends of the paper roll to seal it. The outer head is generally a round kraft paper with a diameter that matches the diameter of the paper roll. One side of it contains hot melt adhesive, which is non-sticky at room temperature and becomes sticky after heating. Because the outer head needs to be placed and heated in advance before pressing, the hot pressing station in the packaging system is usually an offline station, that is, the hot pressing device is arranged in parallel with the conveyor, and the paper roll for outer head pressing needs to be transported from the original conveying station to the hot pressing station for pressing. After pressing, the paper roll is transported to the next station or the original conveying station.

[0003] The heat pressing stations in the above packaging system occupy a large area due to their parallel arrangement, and it takes a long time to transport the paper roll back and forth between the heat pressing station and the conveying station, which greatly reduces the packaging efficiency of the system. Summary of the invention

[0004] The purpose of the present invention is to provide a more reasonable hot pressing device, namely an online hot pressing device, to address the defects of the existing kraft paper packaging system, such as the large floor space occupied by the hot pressing station and the long time-consuming reciprocating transportation. After the paper roll that has completed the front-end packaging process comes out, the outer head can be directly pressed without switching the station, thereby realizing the series arrangement of the hot pressing station and other packaging stations, reducing the floor space and improving the packaging efficiency.

[0005] In order to achieve its purpose, the present invention is implemented through the following technical solutions:

[0006] A hot pressing device comprises an outer head sealing robot, a clamping device, a telescopic device and a hot pressing plate. The outer head sealing robot is placed between an outer head sealing pile and the hot pressing plate, and is used for sucking the required outer heads from the outer head sealing pile according to the specification parameters of the paper roll and placing them on the hot pressing plate; the telescopic device is installed on the clamping device and is connected to the hot pressing plate, and is used for conveying the paper roll to the front of the device for pressing, and then the telescopic device extends out to drive the hot pressing plate to press the two sides of the paper roll, and the clamping device applies pressure to maintain it. After the pressing is completed, the telescopic device drives the hot pressing plate to retract, so that the pressed paper roll continues to move forward, thereby realizing the online pressing of the paper roll.

[0007] Furthermore, the external head sealing robot is composed of a manipulator and a head sealing fixture, and the manipulator is equipped with the head sealing fixture.

[0008] Furthermore, the clamping device consists of a base and a clamping drive mechanism. The base is equipped with a linear guide rail. The clamping mechanism is installed on the base through the linear guide rail and is connected to the reduction motor and the chain. The reduction motor drives the chain to reciprocate on the linear guide rail, driving the telescopic device and the hot pressing plate to complete the pressing action.

[0009] Furthermore, the base is a box-type structure, which is made of welded steel plates and serves as a working platform for the entire hot pressing device.

[0010] Furthermore, the telescopic device consists of a cantilever, a linear guide, and a reduction motor. The cantilever is installed on the linear guide and is connected to the reduction motor and a chain. The reduction motor drives the chain to drive the cantilever to reciprocate on the linear guide, thereby realizing the telescopic movement of the hot pressing plate and achieving the online pressing action.

[0011] Furthermore, the hot pressing plate is composed of a panel, a heating wire, a chassis, and a fan. The panel is provided with suction holes; the back of the panel is provided with a heating wire, a cavity is provided in the chassis, and a fan is installed on the top of the chassis. The fan is used to draw a vacuum, thereby sucking the outer head placed on the panel.

[0012] Furthermore, the panel is made of pure aluminum.

[0013] Furthermore, the heating wire is a straight rod heating wire.

[0014] The beneficial effects of the present invention are:

[0015] 1. The hot pressing station is arranged in series with other packaging stations, which greatly reduces the floor space required for the installation of the packaging system; after the paper rolls that have completed the front-end packaging process come out, the outer head can be pressed directly without switching stations, thereby realizing the series arrangement of the hot pressing station and other packaging stations, reducing the floor space and improving packaging efficiency.

[0016] 2. The robot replaces manual placement of the external head, reducing the direct or indirect contact between personnel and machinery and equipment, which not only reduces the labor intensity of operators but also improves the safety of the entire system;

[0017] 3. Compared with other traditional packaging systems, the various workstations in the packaging system using the heat pressing device of the present invention are arranged in series, and the equipment in each workstation can operate independently online without affecting each other, which significantly improves the packaging efficiency.

After the paper roll arrives at the workstation, the hot pressing platens 4 at both ends automatically extend and move to the middle through the telescopic device 3, and the outer heads on the hot pressing platens 4 are pressed against the ends of both sides of the paper roll, and are pressurized and maintained by the clamping device 2. After the pressing time is reached, the hot pressing platens 4 on both sides retract, and the pressed paper roll continues to move forward.
