Description

Technical Field

[0001] This utility model relates to the field of rubber track technology, specifically to a rubber track pre-applied composite device. Background Technology

[0002] Rubber tracks are tracks made of rubber and skeleton materials. They are widely used in engineering machinery, agricultural machinery, military equipment and robots. Compared with steel tracks, rubber tracks are significantly lighter, which allows tracked vehicles to travel faster and accelerate better. They can also reduce fuel consumption and increase range.

[0003] In the production process of rubber tracks, pre-bonding is a key process, and the performance of its equipment directly affects product quality and production efficiency.

[0004] Existing rubber tracks require conveying the rubber sheet during pre-bonding. During the conveying process, the rubber sheet is prone to deviation and misalignment, causing it to shift its position when it is above the iron teeth, resulting in material waste. Inaccurate bonding can also lead to quality problems in the finished rubber track, such as uneven thickness and weak component connections. Therefore, a rubber track pre-bonding and bonding device is proposed. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This utility model provides a pre-applied molding device for rubber tracks. It has the following beneficial effects:

[0019] (i) The rubber track pre-bonding and bonding device, through the coordinated action of the double-axis threaded rod, control block, connecting plate and limiting ring in the conveying mechanism, can quickly and accurately adjust the distance between the two limiting rings. This allows the device to flexibly adapt to medium-strength rubber rolls and sheets of different widths, and to stably limit the position of the sheet during the conveying process.

With the help of the limit rod, the device can accurately guide and limit the pressure to ensure that the pressure is applied evenly to the bonding parts. At the same time, the heating and pressing plate eliminates air bubbles and gaps on the bonding surface through the dual effects of temperature and pressure, thereby improving the bonding tightness. Through coordinated optimization with the conveying mechanism, it can meet the pre-bonding and bonding production needs of various specifications of rubber tracks. It is suitable for small-batch customization and large-scale standardized production, effectively expanding the production scope of enterprises. Attached Figure Description
