The traditional glue applicator consists of a glue roller, a glue pressing wheel, a glue tank, and a glue quantity adjustment device. The glue roller lifts the glue from the glue tank, the glue quantity adjustment device scrapes off the excess glue from the glue roller, and then the glue roller transfers the glue to the glue pressing wheel. The glue pressing wheel then presses the glue onto the substrate, completing the gluing process. The traditional glue applicator has certain drawbacks. If it is necessary to apply glue on both sides of a substrate, it needs to be done twice. After gluing on the first side and drying, it is then glued on the other side, dried, and adhered, or the first side is glued using the spray glue method. Thus, the process is quite cumbersome. Some people also use the substrate immersion method to achieve double-sided gluing, but some substrate materials are not suitable for immersion and have certain limitations. Moreover, this method has a large amount of glue application and is costly.
This utility model adopts the following technical solution: it includes a machine platform, on which a gluing wheel, a pressure wheel, a gluing groove, and a gluing quantity adjustment device and a driving device are fixed. The driving device is connected to the gluing wheel and the pressure wheel. Two sets of gluing wheels, pressure wheels, gluing grooves and gluing quantity adjustment devices are installed on the machine platform. The substrate is conveyed between the two pressure wheels.
A regulating device is fixedly connected to the pressure wheel.
One set of gluing wheels, pressure wheels, gluing grooves and gluing quantity adjustment devices is fixedly installed on an activity platform. The activity platform is movably connected to the machine platform through a travel adjustment device.
This utility model sets up two sets of gluing devices on one machine platform, and makes the substrate that needs to be glued pass between the pressure wheels of the two sets of gluing devices, so as to realize simultaneous and continuous gluing on both sides. Moreover, the position of the pressure wheels can be adjusted according to different substrates, the operation is simple, the production cost is low, and the production efficiency can be greatly improved. Through testing, simultaneous and continuous gluing on both sides can be achieved, and the position of the pressure wheels can be adjusted according to different substrates, the operation is simple, the production cost is low, and the production efficiency can be greatly improved.
