Description

Technical Field

[0001] The utility model relates to a filling machine, in particular to an automatic feeding structural adhesive filling machine, belonging to the technical field of structural adhesive production. Background Art

[0002] Structural adhesive is a kind of adhesive with high strength and the ability to withstand large loads. It is suitable for bonding strong structural parts. It is also resistant to aging, fatigue, corrosion, impact, and peeling. It has stable performance within its expected service life and simple construction process. Today, filling machines are mainly a small category of packaging machines. In the production process of structural adhesives, filling machines are needed to package the structural adhesives.

[0003] Among them, the "A kind of hard-pack filling equipment for silicone structural adhesive" disclosed in the application number "CN202120712993.0" is also an increasingly mature technology, including a silicone structural adhesive filling machine, a filling tube installed at the glue outlet of the silicone structural adhesive filling machine, the lower end of the filling tube is integrally formed with a connecting ring, the outer side of the connecting ring is sleeved with a sealing rubber ring, the upper end of the inner side of the sealing rubber ring is integrally formed with an upper pressure ring, the inner side of the upper pressure ring is integrally formed with a limiting clamping ring, and a limiting clamping groove is provided at the connection between the filling tube and the connecting ring; the sealing rubber ring is integrally formed on the outer side of the connecting ring through the lower end of the filling tube, so that when the silicone structural adhesive is hard-packed and filled, the inner surface of the hose contacts the sealing rubber ring, which increases the silicone structural adhesive. For the stability of filling, the sealing ring is connected to the connecting ring through the upper pressure ring, the limiting clamping ring, the limiting clamping groove, the support ring and the lower support ring, thereby increasing the reliability of the installation of the sealing ring and facilitating the disassembly and replacement of the sealing ring after damage. After further search, the "A silicone structural adhesive hydraulic filling machine" disclosed with the application number "CN202120755677.1" includes a fixed base plate, and two support plates are fixedly installed in the middle position of the top of the fixed base plate, and the two support plates are symmetrically distributed with each other. The tops of the two support plates are respectively fixed with a first hydraulic rod, and the tops of the two first hydraulic rods are fixed with a fixed frame, and the internal fixed sleeve of the fixed frame is fixed with a second hydraulic rod. This hydraulic filling machine for silicone structural adhesive installs an electronic control valve at the outlet of the filling barrel and uses a rangefinder to monitor the depth of the silicone structural adhesive filled in the barrel to be filled, which is placed between several side panels, in real time. When the barrel to be filled is full, the feedback is sent to the control panel, which controls the electronic control valve to close. This effectively avoids the problem of leakage caused by manual operation of the filling machine and improves the intelligence level of the filling machine.
