Example Embodiment

[0009] see figure 1 , figure 2 , A bubble diameter control system, which includes a bubble forming mold 1, the bubble forming mold 1 is connected to the air inlet duct 2 and the air outlet duct 3, the air inlet duct 2 is connected to the air inlet fan 4, and the air outlet duct 3 is connected to the air outlet The fan 5 forms a cycle of inlet and outlet air. The wind from the inlet fan 4 enters the upper end of the bubble forming mold 1 through the inlet duct 2 and the surrounding air inlets 9 so that the film blown from the bubble forming mold 1 forms a film Bubble 8, three probes 6 are arranged symmetrically on the outside of the bubble forming mold 1. The three probes 6 are symmetrical with the center of the bubble forming mold as the center of symmetry. The three probes are connected to form an equilateral triangle, and the probe 6 is connected to the air inlet fan 4 Control system 7, set the air outlet to be constant, and control the inlet air volume by controlling the wi...

Abstract

The invention provides a film bubble diameter control system which controls the diameter of a film bubble effectively to effectively reduce the loss of a film roll and the waste of raw materials. The film bubble diameter control system comprises a film bubble forming mold. The film bubble forming mold is connected with an air inlet pipeline and an air outlet pipeline. The air inlet pipeline is connected with an air inlet fan, and the air outlet pipeline is connected with an air outlet fan, so as to form an air inlet and outlet circulation. The film bubble diameter control system is characterized in that at least three probes are symmetrically arranged on the outer sides of the film bubble forming mold, and the probes and the air inlet fan are connected with a control system.

Description

technical field [0001] The invention relates to the technical field of film production equipment, in particular to a film bubble diameter control system. Background technique [0002] In the production process of the film, the diameter of the bubble formed by the mold is determined according to the size of the finished film. When the diameter of the bubble is too large for the size of the film, excessive waste will be cut off in the film trimming , resulting in the loss of the film roll, when the diameter of the film bubble is too small for the size of the film, the film bubble cannot meet the size requirements of the film, resulting in defective film bubbles and a waste of raw materials. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a film bubble diameter control system, which effectively controls the diameter of the film bubble, thereby effectively reducing the loss of film rolls and the waste of raw materi...
