[0002] Silicone strips are a material used for sealing, bonding or fixing. They are usually made of silicone and have certain elasticity and water resistance. Silicone strips are widely used in construction, automobiles, electronics, electrical appliances, aviation, ships and other fields to fill gaps, prevent leakage, fix parts, etc. Silicone strips have excellent high and low temperature resistance, aging resistance, chemical corrosion resistance, etc., so they are widely used in various environments.

[0003] The authorization publication number "CN 214820762 U" records "a silicone strip extrusion die with a cooling function, comprising a barrel, a box body is connected to the bottom of the barrel, a slide seat is connected to the top of the box body, a blade is connected to the inside of the slide seat, the inside of the blade includes a slider, a pull rod is connected to the top of the blade, a first air inlet fan is connected to the bottom of the box body, a second ventilation hole is opened inside the box body, a second air inlet fan is connected to the inside of the second ventilation hole, and a screen is connected to the inside of the second ventilation hole near the second air inlet fan. The utility model uses the first air inlet fan and the second air inlet fan, and after the silicone strip is cut and falls into the box body, the first air inlet fan and the second air inlet fan are turned on at the same time, so as to realize multi-directional cooling of the silicone strip, improve the cooling efficiency of the silicone strip, and solve the problem of slow molding of the silicone strip and reduced production efficiency due to lack of cooling structure".

[0004] The above patent effectively improves the cooling efficiency of the silicone strips after extrusion, but the above patent lacks a protective structure for the silicone strips during extrusion. During the discharging process, some silicone strips will be deflected downward due to gravity, resulting in wrinkles on the outer wall of the silicone strips. At the same time, after cutting, the silicone strips fall directly into the box body, and the surface of the silicone strips is prone to damage, affecting the processing quality of the silicone strips.
