Description

Technical Field

[0001] The utility model relates to the technical field of oil coating devices, and more specifically, to an oil coating device for producing PET plastic sheets. Background Art

[0002] In existing technologies, it is crucial to ensure that the PET plastic sheet is stably fixed during the oiling process, which helps to ensure uniform oiling and avoid uneven oiling caused by material movement. However, existing oiling devices may affect the fixation of the PET sheet due to design defects. In this case, the water flow will not only interfere with the oiling process, but may also cause the position of the PET sheet to shift, affecting the oiling quality and production efficiency.

[0003] During the maintenance and operation of the oiling device, it may be necessary to quickly release the fixing of the oiling pipe for cleaning, inspection or replacement. However, existing devices may lack a convenient quick release mechanism, which makes it impossible for operators to quickly and easily release the fixing of the oiling pipe. This inconvenience may be caused by the complex design or improper positioning of the fixing fasteners, making it difficult to quickly operate when needed.

[0004] Replacing the oiling pipe is part of routine maintenance, especially when it is worn or clogged. However, existing oiling devices may not take into account the need for quick replacement, resulting in a cumbersome and time-consuming replacement process. This may be due to limited internal space in the device, complex connection methods for the oiling pipe, or lack of specialized replacement tools. Utility Model Content

At this time, the movable sleeve 9 is released, and the locking block 13 is driven to move under the action of the tension spring 14, so that the locking block 13 is fitted with one end of the rotating block 16, thereby completing the movement process of the movable sleeve 9.

[0038] After the movable sleeve 9 completes the moving process, the movable sleeve 9 releases the contact with the clamping block 22, so that under the action of the second spring 23, the clamping block 22 is driven to slide along the fixed sleeve 8, so that it is removed from the clamping groove 21 on the movable tube 19.
