Self-adaptive adhesive tape unwinding device

Abstract

The invention discloses a self-adaptive adhesive tape unwinding device. The self-adaptive adhesive tape unwinding device comprises an adhesive tape sleeve, a driving gear, a large transmission gear, a small transmission gear, a spring gear, a spring spindle, a spring, an electromagnetic clutch, a spring box and a spring gear box; the adhesive tape sleeve is connected with the spring gear box, and the electromagnetic clutch is used for controlling the meshing state of the transmission gears. According to the device, adhesive tape can be automatically wound when the adhesive tape is not stressed and is controllable in unwinding when the adhesive tape is stressed through the counter-acting force generated when the spring is screwed in the unwinding process of the adhesive tape. The self-adaptive adhesive tape unwinding device is mainly applied to packaging machinery for adhesive tape bundling, the adhesive tape is attached to an object through elastic potential stored by the spring, adhesive tape bundling on objects with different sizes and shapes is achieved, the problem that a programmed unwinding device of a traditional mechanical production line only can bundle objects with fixed sizes and shapes is solved, and the complex mechanism of an existing packaging machine for bundling the objects with different sizes is simplified. When the self-adaptive adhesive tape unwinding device is combined with other devices, bundling on the objects with different sizes and shapes can be achieved.

Description

Technical field [0001] The invention relates to an unwinding device, in particular to an adaptive tape unwinding device controlled by a spring. Background technique [0002] With the popularization of online shopping, the sales volume of online store products is increasing. When online store entrepreneurs tape packaging and bundling products, there is a heavy workload and shortage of manpower, especially in the economic development of Internet +. The labor force of entrepreneurs urgently needs to be liberated. In the existing commodity packaging bundling and encapsulation stages, manual bundling or mechanical semi-automatic bundling is often used, which is labor intensive and low in efficiency. [0003] At present, most of the existing domestic tape strapping machines are packaged for products with a single size and shape. However, there are many types of products in online stores and different packaging sizes. The existing single-size strapping machines are not suitable for onlin...

AI Technical Summary

Problems solved by technology

During the binding process, the whole tape will rotate relative to the object while the tape will rotate and release glue. During this period, the tape must have a certain tension to fit the object. The amount of glue released by the tape changes with the surface of the object. There are some changes in the delivery speed, which leads to a more complicated bundling process, which is why most of the adhesive tape dispensing devices are controlled by programs.
