Problems solved by technology

If the tension of the aluminum film is too large, problems such as film breakage or poor sealing are likely to occur
If the tension of the aluminum film is too small, it is prone to problems such as sealing folds and easy ventilation, which will affect the shelf life or be judged as substandard products
[0005] In the existing solutions, most of them use the tension swing rod and magnetic powder brake to control the constant tension. This kind of solution has poor tension stability and cannot realize the plate registration function.

Abstract

The invention provides a heat sealing method for a blister machine. In the blister machine, a formed film enters the heat sealing mechanism from a forming mechanism, and a covering film enters the heat sealing mechanism from a covering film unwinding mechanism, so that the covering The film covers the surface of the forming film at the heat-sealing roller; in order to realize the constant tension control of the covering film, the heat-sealing method of the blister machine of the present invention utilizes the servo feedback of the heat-sealing roller, according to the arc length of the heat-sealing roller rotation Calculate the current unwinding roll diameter of the cover film and the rotation center angle of the cover film shaft, and calculate the driving torque of the cover film shaft according to the current unwinding roll diameter of the cover film shaft, so as to realize the full process of the cover film during the heat sealing process of the blister machine. Constant tension control, which in turn greatly improves the tension stability of the cover film during the heat sealing process of the cover film and the forming film, improves the sealing performance of the final product, and improves the production yield of the product.

Description

technical field [0001] The invention relates to the technical field of blister machines, in particular to a heat sealing method for a blister machine. Background technique [0002] Aluminum-plastic blister packaging is currently the main product packaging method in the pharmaceutical machine industry. Most of the tablet-type finished medicines need to go through this process before they can be sold as products in the market. Its working process is to form and pack various tablets with PVC on aluminum-plastic boards, which is suitable for tablets, capsules, capsules, plain tablets and various special-shaped tablets of various specifications. In order to realize high-speed packaging of tablets with different sizes and shapes, the control system is required to have high-speed, accurate and coordinated control functions. [0003] The flat-bed automatic blister packaging machine is used to package the package. First, the PVC sheet material is heated by the upper and lower heatin...
