Description

Technical Field

[0001] This application relates to the technical field of glass bottle forming molds, and in particular to a device for suppressing corrugated glass bottle texture. Background Technology

[0002] During glass bottle production, periodic horizontal stripes (commonly known as "washboard marks") easily appear on the bottle surface, severely affecting product appearance quality and market competitiveness. Currently, the industry commonly uses methods such as mold polishing and lubricant spraying to alleviate this problem, but these methods cannot fundamentally eliminate the formation mechanism of washboard marks. With the widespread adoption of high-speed bottle-making machines (production speeds can reach over 200 bottles per minute), traditional methods are no longer sufficient to meet the demands for high-precision surface quality control.

[0003] Existing processing methods mostly fall into the following categories: Mold polishing technology: The friction coefficient is reduced by regularly polishing the inner wall of the mold manually or mechanically. The advantage is that it is easy to operate, but the disadvantage is that the polishing cycle is short (the machine needs to be stopped every 4 hours) and it cannot eliminate melt fluctuations during the molding process.

[0004] Lubricant spraying system: Automatically sprays graphite or silicone oil-based lubricant before the mold closes. The advantage is that it can produce continuously for more than 8 hours. The disadvantage is that it is easy to cause environmental pollution and the residue may contaminate the bottle mouth sealing surface.

[0005] Vibration suppression device: Adding shock absorbers to the conveyor track reduces the transmission of mechanical vibration. It is effective for low-frequency vibration caused by the motor, but ineffective for high-frequency melt fluctuations.

[0006] Regarding the aforementioned technologies, it has been found that existing methods all intervene in the results rather than the causes, and cannot block the core formation mechanism of the corrugated glass pattern, namely the periodic oscillating flow of the glass melt within the mold. Utility Model Content

[0007] In order to block the periodic oscillating flow of molten glass in the mold, this application provides a device for suppressing the corrugation pattern on a glass bottle body.

[0008] The glass bottle body anti-chafing texture device provided in this application adopts the following technical solution: A device for suppressing corrugated glass bottle marks includes a mold base. A first outer mold is mounted on the upper surface of the mold base and is fixedly connected to the mold base. A second outer mold is fastened to the front end of the first outer mold. The first and second outer molds are inserted and fixedly connected, and locking brackets are also installed on the first and second outer molds for mutual locking. An inner mold is mounted on the inner surface of both the first and second outer molds and is fixedly connected to both the first and second outer molds. A spiral groove is formed on the inner surface of the inner mold. A detection box is also installed in the mold base, and an airflow guiding component is also installed in the detection box.

[0009] By adopting the above technical solution, the equipment is designed with a mold base, an outer forming mold, an inner forming mold, a detection box, and an airflow guiding component. This ensures that during use, the outer forming mold (part one) and outer forming mold (part two) can cooperate to form a complete forming mold shell structure. The inner forming mold is then installed within this shell as the main forming structure for stable forming of glass bottles. The spiral grooves on the inner forming mold guide the airflow, causing axial flow of the melt and disrupting the propagation path of transverse oscillation waves, thus reducing the formation of ripple marks. The detection box and airflow guiding component allow for real-time monitoring and adjustment of the airflow during the forming process. A piezoelectric sensor monitors melt pressure fluctuations in real time; when a pressure pulsation with a frequency >200Hz is detected, the control system automatically adjusts the airflow pressure, further improving the ability to suppress ripple marks.

[0010] Optionally, the mold base includes a housing and a placement bracket, wherein the placement bracket is evenly installed on the lower end face of the housing along the circumferential direction and is fixedly connected to the housing.

[0015] By adopting the above technical solution, the second outer mold includes a mold shell and a connecting side plate, and the connecting side plate is integrally formed with the mold shell.

Through the locking action of the locking insert, the stability of the connection between the forming outer mold one and the forming outer mold two can be further enhanced, preventing the mold from loosening during the glass bottle forming process, thereby ensuring the forming quality of the glass bottle.

[0020] Optionally, the detection box includes a main box body, a box cover, and an embedded piezoelectric sensor. The box cover is installed in the main box body, and the embedded piezoelectric sensor is vertically fixed at the center of the upper surface of the box cover.

[0021] By adopting the above technical solution, the detection box includes a main body, a lid, and an embedded piezoelectric sensor. The embedded piezoelectric sensor can detect pressure changes in real time during the glass bottle forming process and transmit the signal to the control system. By monitoring pressure changes, the operating parameters of the airflow guiding component can be adjusted in a timely manner to adapt to different forming requirements and improve the effect of suppressing corrugated patterns.
