Description

Technical Field

[0001] The utility model relates to the technical field of hot presses, in particular to a fixing mechanism which is convenient for replacing an anti-sticking pad. Background Art

[0002] In sports events, number plates are often used to identify competitors to better distinguish them. Professional sports events and teams typically have dedicated numbered uniforms, with each number representing a different competitor. However, in casual events like factory or school sports meets, competitors are often non-professionals and lack dedicated uniforms. The common solution is to use temporary paper number plates secured to clothing with paper clips. However, after strenuous exercise, these paper number plates can become wet and shaky, causing them to fall off, significantly impacting the progress of the event.

[0003] In order to solve the above situation, the applicant has prepared a race number plate backpack that takes into account both cost and replacement effect and applied for a utility model patent. The number plate backpack is processed by a hot pressing and bonding process. However, during processing, the existing hot press machine has only two layers of fabric. Whether it is placed right side up or upside down, it is easy for the plastic fabric of the backpack to stick to the mold, affecting the loading and unloading of the product. Although the backpack with hemming treatment can prevent adhesion, the hemming process will greatly increase the processing time and increase the processing cost. The existing technology can solve the above problem by adding an anti-sticking pad, but the anti-sticking pad is generally fixed to the bottom mold with double-sided tape. Not only is the adhesion not very strong, the viscosity will be reduced under high temperature conditions, and it is easy to be torn off when the worker spreads it flat and pulls it. When replacing the anti-sticking pad, there will be adhesive residue that affects the next bonding, and it is more troublesome to remove. There is room for further improvement. Utility Model Content
