Description

Technical Field

[0001] The utility model relates to the technical field of silicone tape production, in particular to a silicone hot-pressing connection jig. Background Art

[0002] Silicone tape is a type of tape made of silicone rubber, also known as self-fusing tape or self-melting tape. Unlike traditional tapes, silicone tape does not rely on adhesives to stick to the surface, but adheres to itself to form a strong and flexible bond. This unique property makes it ideal for a variety of applications. Silicone tape has a strong yet flexible bond that can stand the test of time. The waterproofness and durability of silicone tape make it ideal for patching pipe leaks, repairing broken hoses, or sealing gaps in outdoor equipment. When producing silicone tape, a hot press joining jig is required to connect and fix the silicone products.

[0003] At present, the existing silicone hot pressing joining fixture connects two products together during the hot pressing process and fixes them by hot pressing. However, the silicone product located on the upper side is prone to falling off, affecting the heating and joining process of the product. The existing technology has also made improvements to this, using a clamping component to fix the silicone product and then performing the hot pressing joining operation. However, the clamping component and the silicone product are in a close contact state, and the silicone product will undergo a certain deformation during the hot pressing process. At this time, the clamping part of the silicone product will be damaged due to excessive friction. Therefore, further improvements are needed on this basis. Utility Model Content
