Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of glass processing, and particularly relates to a manufacturing process of mechanically automatic patching of glassware. BACKGROUND

[0002] Glass, as a material with excellent aesthetic and practicality, is widely used in food industry, chemical industry and daily life. Among them, glass cups, as an important branch of glass products, are indispensable containers in life. In particular, glassware formed by pressing is favored due to its various shapes and low price. With the improvement of people's living quality, the demand for glassware has gone beyond basic practicality, and people are more pursuing artistic beauty and decoration. By fusing various colors and shapes of glass color patches on the outer wall of glassware, the appearance grade of the product can be greatly improved, so as to better meet the aesthetic needs of modern life.

[0003] The prior art usually combines the patch and the glassware through a "hot-state combination" or "cold-stick sintering" process. The hot-state combination process refers to directly combining the decoration with the glassware body when the glassware body is still in a high temperature and plastic state. The core is "hot processing". The cold-stick sintering process refers to combining the glassware and the patch after they are completely cooled to room temperature (i.e. "cold state"), and then using an adhesive to combine them, and then fusing them through secondary heating. The core is "stick first and then sinter". The patch combined by the cold-stick sintering process has poor firmness, and the entire product needs to be refired, while the hot-state combination usually requires hot processing, which requires artisans to operate two hot and soft parts in a very short time, and relies too much on manual operation.

[0004] In the process of researching and developing how to avoid the defects of the "hot-state combination" and "cold-stick sintering" processes, it is found that using local melting technology to patch when making such patch glass handicrafts can make the patch firmness good, but still cannot avoid the need for pure manual operation. Specifically, the operator needs to first hold a spray gun to locally heat the specified position of the outer wall of the glassware to a slightly molten state, and then use a tool to stick the glass color patches one by one to the molten position. By repeating this operation, multiple color patches can be stuck to the body of the vessel. This process has many inherent defects:

[0005] First, production efficiency is low and costs are high. The entire heating and bonding process relies heavily on manual labor, and only one location can be processed at a time. For a vessel requiring multiple colored films, the operation is cumbersome and time-consuming, resulting in limited production capacity and high costs. Second, there are significant safety hazards. Operators must be in close proximity to the high-temperature glassware and the torch flame for extended periods, greatly increasing the risk of burns. This places high demands on the skills and experience of operators, and the working environment is dangerous. Third, product quality stability is poor. Manual operation makes it difficult to ensure consistent heating temperature and duration each time. The placement and pressure of the films are entirely based on feel, easily leading to placement deviations, weak adhesion, or uneven appearance due to operator fatigue or errors, severely impacting product yield and aesthetics.

[0006] Therefore, how to break through the limitations of traditional manual craftsmanship and design a glassware patching technology and equipment that can achieve automated and large-scale production while ensuring operational safety and stable product quality has become an urgent technical problem to be solved in this field.

At the same time, it liberates workers from harsh working environments with high temperatures and the risk of burns, and the most dangerous burning and pasting steps are completed by automated devices, resulting in extremely low safety risks in production.

[0047] (2) The mechanical positioning described in this invention ensures that the patch is positioned accurately and consistently, avoiding problems such as positional deviation and poor adhesion caused by manual operation. This invention ensures that the patch is firmly fused to the vessel body through controllable burning temperature and mechanical pressure; the subsequent flame polishing process makes the mouth and body of the product more rounded, smooth, and glossy.

[0048] (3) This invention adopts a novel automated approach that combines “independent preparation of cold-applied patches” with “local reheating of the molded vessel”, breaking away from the traditional “hot bonding” or “cold bonding and sintering” process framework, and providing a new solution for glass decoration. At the same time, standardized patches can be designed and stored as “standard parts”, which facilitates the rapid production of products with different patterns, and the appearance of different batches of the same product is highly consistent.

[0049] (4) The glassware patching device used in this invention integrates multiple functions such as positioning, clamping, burning, and bonding. The actions are coordinated and continuous, realizing closed-loop automated production. Through mechanical structures such as linkage mechanisms, it ensures that all hinge plates can be closed synchronously and smoothly towards the central vessel, with uniform force and reliable bonding.
