Description

Technical Field

[0001] The invention relates to the technical field of epoxy structural adhesive processing, and in particular to a feeding device for epoxy structural adhesive processing. Background Art

[0002] Epoxy structural adhesive is a high-performance structural adhesive based on epoxy resin, which has excellent bonding performance, mechanical properties and environmental resistance. It is widely used in various industries, especially in occasions that require strong bonding, high temperature resistance and chemical corrosion resistance. Due to its unique properties, epoxy structural adhesive has been widely used in construction, automobile, aerospace, electronics, machinery manufacturing and other fields.

[0003] Epoxy structural adhesives are usually composed of two parts: epoxy resin and hardener (also called curing agent). Depending on the hardener, the performance of epoxy structural adhesives will vary. The main ingredients include:

[0004] Epoxy resin: provides adhesive bonding and structural strength. Common epoxy resins include bisphenol A, bisphenol F, epichlorohydrin, etc. Hardener: a substance that promotes the curing of epoxy resin. Common hardeners include amines, anhydrides, phenolic compounds, etc. Filler: In order to improve the performance of adhesives, various fillers such as glass fiber, graphite, carbon fiber, etc. are usually added to epoxy resin to increase the strength, rigidity and wear resistance of the adhesive.

[0005] The document with prior art publication number CN217125972U provides a feeding device for epoxy structural adhesive processing, which is conducive to realizing the function of facilitating scraping by setting a lifting mounting seat, an annular groove, an annular scraper plate, an exhaust hole, a lifting rod and an operating head.

[0006] When the prior art is used, the raw materials need to be poured into the feeding barrel through the feed hopper. In the feeding device for epoxy structural adhesive processing, the colloidal raw materials in the raw material barrel are easily attached to the barrel wall due to their strong viscosity. Since the prior art is not convenient for completely discharging the colloidal raw materials attached to the raw material barrel, the raw materials are wasted, which not only increases the production cost, but also may affect the production efficiency. At the same time, the colloidal raw materials cannot be discharged smoothly from the barrel, and the operator is usually required to clean the raw material barrel with tools or dig it manually, which will increase the labor intensity and reduce the production efficiency.

[0007] In summary, the prior art lacks a technology for completely discharging the colloid raw materials attached to the barrel by using centrifugal force when feeding epoxy structural adhesive. Summary of the invention

[0008] The purpose of the present invention is to solve the shortcomings existing in the background technology and to propose a feeding device for epoxy structural adhesive processing.

[0021] 3. By setting up an arc-shaped rack, the sealing cover on the unloading seat can be automatically opened and closed while the turning frame is turning. Through the linkage of the arc-shaped rack and the turning frame, the opening and closing process of the sealing cover is fully automated, without manual intervention, reducing the errors and complexity of human operation. At the same time, when the turning frame is turning and feeding, it will automatically drive the opening and closing of the cover. During the feeding process, the system ensures the smooth pouring of raw materials. When no material is added, the automatic closing of the sealing cover effectively prevents the entry of external pollutants and ensures the cleanliness of the raw materials. The automatic opening and closing mechanism not only saves time, but also ensures the efficient and stable operation of the equipment and reduces the difficulty of maintenance.
