Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive dispersion technology, and in particular to an integrated adhesive dispersion and pressing machine. Background Technology
[0002] With the rapid development of the electronics, automotive, new energy, and construction industries, the market demand for adhesives and sealants continues to rise. In the new energy field, the thermal encapsulation of power batteries and the sealing and bonding of photovoltaic modules also rely on high-quality adhesives. However, traditional adhesive dispersion and pressing processes employ a step-by-step production method, first mixing materials in a dispersion device and then transferring them to a pressing device for discharge. This not only results in low production efficiency but also easily leads to material loss and impurity contamination during the transfer process, failing to meet the demands of modern industry for efficient and precise production. Traditional adhesive dispersion and pressing equipment has many limitations. In the adhesive dispersion stage, ordinary mixers are ineffective at dispersing high-viscosity adhesives, easily causing uneven mixing and particle agglomeration, affecting the performance stability of the adhesive. In the pressing stage, traditional pressing equipment suffers from inaccurate pressure control and large fluctuations in discharge flow, making it difficult to guarantee coating quality for processes requiring high application precision. To address the shortcomings of traditional equipment, an integrated adhesive dispersion and pressing machine has emerged. It integrates the two core functions of adhesive dispersion and pressing into one unit, achieving a fully integrated operation from raw material mixing to finished product discharge through innovative design and advanced technology.
[0003] A search revealed Chinese Patent Publication No. CN217746838U, which discloses a dispersion device for high-density, high-proportion filler adhesives. The device includes an adhesive tank, a first dispersion plate, a second dispersion plate, a baffle, a stirrer, a ball mill, and a dual-flow air pump. The adhesive tank has a receiving cavity, with a dispensing port at its bottom. Both the first and second dispersion plates are disposed within the receiving cavity. The first dispersion plate has multiple first dispersion holes, and the second dispersion plate has multiple second dispersion holes. The baffle is disposed on the inner wall of the receiving cavity, and multiple through holes are formed on its side. The stirrer is disposed on the adhesive tank. By using a dual-flow air pump to change the circulation direction, the problem of filler accumulation in the adhesive is solved. In addition, the use of a dual dispersion plate structure can avoid uneven adhesive pressure between the two dispersion plates and optimize the dispersion effect. The setting of a stirrer and baffle further enhances the dispersion effect. The external ball mill thoroughly disperses the small molecule agglomerates attached to the filler, making the adhesive more uniformly dispersed. However, the stirrer can only achieve simple rotation, and the material flow is singular, which can lead to stratification, clumping and stirring dead zones. Utility Model Content

The bottom of the long rod 3052 can be engaged with the bottom of the positioning sleeve 3051, and the long rod 3052 and the positioning sleeve 3051 can be stably connected by the nut 3054. The position of the display sleeve 3053 can be adjusted during pressing.
