[0001] The utility model relates to the technical field of devices for coating the periphery of strip plastic parts, in particular to a device for coating the periphery of a strip-shaped plastic part. Background Art

[0002] The hot-pressing film laminating device for plastic parts is a device specially used for laminating the surface of plastic parts. The device heats the laminating material to a suitable temperature to enhance the laminating effect, and then closely fits the laminating film around the plastic parts to ensure that the laminating film is firm, flat and free of bubbles.

[0003] In the existing technical scope, for the device for coating all around strip plastic parts, usually only one or two strip plastic parts are placed under the coating material. This layout causes the device to only be able to coat one or two strip plastic parts during each operation. When faced with some tasks that require large-scale coating, the coating efficiency of this device that can only process one strip plastic part at a time is extremely low. For example, on the production line of a certain electronics factory, due to the insufficient efficiency of the existing device for coating all around strip plastic parts, a large number of orders are piled up and the market demand cannot be met in time. This situation fully exposes the limitations of the existing equipment in dealing with large-scale coating tasks, and further highlights the urgency and necessity of designing a new device. Therefore, it is necessary to design a device for coating all around strip plastic parts to solve the above problems. Utility Model Content
