Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof roll packaging, and in particular relates to a waterproof roll packaging device. Background Art

[0002] Waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist the seepage of external rainwater and groundwater. As a leak-free connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project. The waterproof material product made by impregnating asphalt or polymer waterproof materials on the carcass is provided in the form of a roll, which is called waterproof membrane.

[0003] For example, the Chinese patent with publication number CN217023177U discloses a packaging device for waterproof coiled material production. The patent can heat the sealing strip by turning on the electric heating plate, and can convey the plastic packaging bag containing the waterproof coiled material by using the conveyor belt. The two baffle strips can prevent the waterproof coiled material from rolling significantly on the conveyor belt, so that the plastic packaging bag containing the waterproof coiled material can be conveyed more smoothly and effectively. By starting the cylinder, the pressure seat can be controlled to move down to press and contact with the top of the fixed seat, and the pressure seat can be used to flatten the bag mouth of the plastic packaging bag and fix it on the fixed seat for subsequent Sealing process, by starting the motor to control the rotation of the cam, the rotation of the cam can push the mounting plate, the electric heating plate and the sealing strip to move vertically downward, the spring is stretched and deformed to generate elastic force, when the sealing strip with heat drops to the lowest position, the bag mouth of the plastic packaging bag can be heated and sealed, as the cam continues to rotate, under the elastic force of the spring, the mounting plate can be controlled to drive the telescopic rod, the electric heating plate and the sealing strip to move vertically upward and gradually return to their original positions, by starting the cylinder reset work, the pressure seat can be controlled to rise back to its original position, and the conveyor belt can be controlled to rotate again to convey the sealed and packaged waterproof membrane away.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use, such as: the packaging bag containing the waterproof coiled material is sealed by a heating plate and a sealing strip, and the length of the heating plate and the sealing strip may be fixed. Therefore, when the diameter of the bag opening is large, the heating plate and the sealing strip may not be able to fully contact the bag opening of the packaging bag due to their length limitations, which may affect the sealing effect of the waterproof coiled material.

[0006] In view of this, we propose a waterproof roll packaging device. Utility Model Content

[0007] The purpose of the utility model is to provide a waterproof roll packaging device to solve the problems raised in the above background technology.

[0012] A reinforcement component is arranged on one side of the conveyor body and is used to reinforce the mounting plate when it moves.

[0013] In this technical solution, the staff places the packaging bag containing the waterproof coiled material on the conveyor belt of the conveyor body, and then the conveyor body transports the packaging bag to the position of the packaging table, the staff uses the second electric push rod, and then the telescopic rod of the second electric push rod moves upward to drive the sealing plate to rotate. At this time, the sealing plate will rotate and fall to the surface of the packaging table, and then flatten the bag mouth of the packaging bag on the surface of the packaging table. After the above steps are completed, the staff uses the driving motor, and then the rotation of the driving shaft of the driving motor will drive the gear to rotate, and then under the gear and rack meshing transmission action, the mounting plate, positioning block, mounting plate and driving motor will move along the direction of the rack, and when the mounting plate moves to the upper part of the packaging table When the worker uses the first electric push rod, the telescopic rod of the first electric push rod moves downward, which will drive the connecting plate and the heating plate at the bottom to move, and make the heating plate contact the bag opening of the packaging bag on the surface of the packaging table, and then the worker uses the heating plate, and the heated heating plate will perform hot-melt sealing on the bag opening of the packaging bag, thereby achieving the effect of packaging the packaging bag with waterproof coiled material. In this process, since the positions of the mounting plate and the heating plate can be moved, when the worker is packaging the packaging bag with a larger diameter, the worker can control the moving distance of the mounting plate and the heating plate to package the packaging bags of different diameters, thereby achieving the effect of facilitating the packaging of waterproof coiled material packaging bags of different diameters.

[0023] In the above technical solution, further, a rubber pad is fixedly installed on the bottom surface of the pressing plate.

[0024] In this technical solution, the pressing plate is prevented from breaking the surface of the waterproof coiled material packaging bag.

[0025] The beneficial effects of the utility model are:
