Description

Technical Field

[0001] The utility model relates to the technical field of canning machines, in particular to an unsaturated polyester resin filling machine. Background Technique

[0002] Unsaturated polyester resin is generally a linear high-molecular compound with ester bonds and unsaturated double bonds formed by the polycondensation of unsaturated dibasic acids and diols or saturated dibasic acids and unsaturated diols. On its backbone main chain, it contains both polyester chain bonds and unsaturated double bonds. At the same time, carboxyl groups and hydroxyl groups are carried at both ends of the macromolecular chain. These characteristics enable unsaturated polyester resin to undergo copolymerization cross-linking reactions with vinyl monomers (such as styrene), thus changing from an insoluble and fusible state to an insoluble and infusible state. Due to its excellent corrosion resistance, weather resistance, wear resistance, and relatively high mechanical strength, etc., unsaturated polyester resin is mainly applied to motor rotor products, etc.

[0003] The unsaturated polyester resin filling machine is mainly used to quantitatively and accurately fill liquid materials such as unsaturated polyester resin into specified containers. This equipment usually has characteristics such as high precision, high efficiency, and easy operation, and can meet the requirements for filling precision in industries such as chemical engineering, coatings, paints, and resins.

[0004] Its main function is to automatically, accurately, and efficiently fill the unsaturated polyester resin stored in a storage tank or container into a target container, such as a barrel, bottle, or other special packaging, mainly based on metering and filling technologies. The equipment extracts a set amount of unsaturated polyester resin from the storage tank through an accurate metering system and injects the material into the container through a filling head. During the filling process, the equipment will automatically adjust according to preset parameters to ensure the accuracy and stability of the filling amount.

[0005] Although the canning machine in the existing structure is filled with an automatic metering device for the canning head, during the use of some filling heads at present, materials will remain in the canning head. When the canning head stops the canning work, due to the high viscosity and high fluidity characteristics of the polyester resin itself, the canning head will have a dripping phenomenon.
