Description

Technical Field

[0001] The utility model relates to the technical field of goods packaging, in particular to a winding film repair welding device. Background Art

[0002] Winding packaging is a common packaging method for goods. Winding packaging means using a winding film to wrap the goods on all four sides on a conveyor belt and cutting the winding film after winding. After the winding film is cut, the end of the outermost winding film will form a winding film tail.

[0003] In the goods packaging process, some goods need to be directly transported into the automated storage and retrieval system (AS / RS) for storage after packaging. Therefore, there are high requirements for the treatment of the winding film tail in the winding packaging process. In particular, the film tail cannot be left long. Once the film tail is too long or the film tail is not closely attached to the goods and drifts, it will hinder the transportation and storage process of the goods, and then affect the efficiency of transporting the goods into the AS / RS. Therefore, the existing goods winding packaging process often needs to weld the film tail to the winding film layer on the surface of the goods to avoid the film tail from drifting.

[0004] The existing technology for welding the film tail to the winding film layer on the surface of the goods is generally realized by a film welding device integrated in the winding device. The winding device is used to wind the goods first, and then the film tail is welded to the goods and the film tail is cut. However, on the one hand, the welding position of the film welding device integrated in the winding device is fixed, and both the film welding device and the film tail cutting device are integrated on the winding device, so the end of the film tail cannot be completely welded to the winding film layer; on the other hand, when the welding quality is poor and the film tail drifts after welding, it is necessary to stop the transportation of the goods after winding and occupy the entire winding device to repair weld the current goods, which affects the winding efficiency of the goods. Summary of the Utility Model

[0005] Aiming at the problems that the welding position of the film welding device integrated in the winding device in the prior art is fixed and the end of the winding film tail cannot be completely welded to the winding film layer; repairing and welding the winding film requires occupying the entire winding device and affecting the winding efficiency of the goods, the utility model provides a winding film repair welding device, which can avoid the winding film tail from drifting, so that the goods wrapped by the winding film meet the requirements for entering the AS / RS; the repair welding process does not affect the winding process of the goods and can improve the winding efficiency of the goods.

[0006] The utility model provides a winding film repair welding device. A fixed frame is connected to the top of the frame. A cylinder and a linear guide rail are installed on the fixed frame. The linear guide rail includes a guide groove and a guide rail slider installed on the guide groove. The guide rail slider can slide along the guide groove. The moving end of the cylinder and the moving direction of the guide rail slider are the same. The moving end of the cylinder and the guide rail slider are respectively connected to a vertically arranged moving bracket. At least two heating block assemblies are vertically arranged on the side of the moving bracket away from the cylinder and the linear guide rail.

[0007] Further, the heating block assembly includes a heating block support plate, which is connected to the moving bracket. At least two heating block support shafts are installed on the heating block support plate. The heating block support shafts are connected to the heating block pads, and the heating block pads are connected to the heating blocks. The heating blocks are electrically connected to the power supply module.

[0008] Further, a compression spring is installed on the heating block support shaft.

[0009] Further, the movable end of the cylinder is sequentially connected to the floating joint and the moving bracket. The floating joint can improve the assemblability of the moving bracket and the movable end of the cylinder, absorb and correct the lateral force, achieve flexible connection, and avoid breakage of the movable end of the cylinder.

[0010] Further, an infrared sensor is provided on the moving bracket, which can monitor whether there is a cargo in front of the moving bracket.

[0011] Further, the heating block is connected to a thermometer, and the thermometer is electrically connected to a temperature display device, which can monitor and display the heating temperature of the heating block.

[0012] Further, screw holes are provided at the bottom of the frame, and screws can be used in cooperation with the screw holes to fix the frame on the ground or the guide rail.

[0013] The beneficial effects of the present utility model are as follows:

[0014] The winding film repair welding device provided by the present utility model can repair weld the film tail of the winding film on the basis of the first film welding, which can avoid the dispersion of the film tail of the winding film, so that the goods wound by the winding film meet the requirements for entering the automated storage and retrieval system; the winding film repair welding device can be arranged at the rear section of the winding equipment, and the repair welding is carried out after the goods winding process is completed and the goods are transported to the downstream by the conveyor line, which does not affect the winding process of the goods and improves the winding efficiency of the goods.
