Description

Technical Field

[0002] With the development of science and technology and the improvement of people's quality of life, glass lamp products have been widely used in the field of daily life. However, high borosilicate lamp products are mainly shaped like zodiac signs, animals, plants, and landscapes. In order to present realistic object images, it often requires the cooperation of multiple people and multiple processes. However, the order volume of such products is limited, and the process is complicated. At present, there is no systematic automated processing and production. Traditional manual operations are still used to complete them. Due to independent operation of employees and scattered workstations, each workstation needs to be equipped with a heat preservation and heating furnace to heat the product. The temperature adjustment depends on the experience and cognition of each employee to control the preheating and heating temperature of the product. Due to the limitations of everyone's technical understanding and experience, the degree of mastery of the fire is different, and the consistency of the process temperature cannot be accurately guaranteed, resulting in large quality deviations at the back end, product explosions occur from time to time, and there are many subsequent quality problems of the products produced, thus affecting the overall qualification rate. At the same time, under the scattered workstation layout, employees operate individually. The semi-finished products produced in each process need to be cooled at each workstation before being transferred to the next process for production. Before the next process is produced, they need to be preheated and heated again. After the finished product is produced, it needs to be cooled and transferred to the annealing furnace for preheating and annealing again, resulting in repeated preheating and heating and repeated energy consumption, which leads to high energy consumption per unit product. In addition, there is no full-process assembly line production, product transfer is frequent, and production efficiency is low. Therefore, developing an integrated production line with preheating, heating, and conveying functions, connecting all links of lamp production, and having an automated production line for glass lamp products with high conveying efficiency, precise temperature control, and high degree of automation is of great significance to equipment development, process standardization, and improving product quality stability. At the same time, unified management and centralized control are conducive to energy consumption control and reduction. Summary of the invention

[0015] For the sake of simplicity, certain technical features well known to those skilled in the art are omitted in the following description.

[0016] According to one embodiment of the present application, the integrated lamp heating and conveying production line includes conveying, preheating, heating, and insulation functions. The line is flexible to adjust and highly compatible, meeting the production requirements of various customized lamp products, high boron glassware, handicrafts, and wine glasses. The line has the basic functions of automatic conveying, automatic heating, automatic insulation, and reciprocating conveying of workstations. The line meets the production requirements of lamp products of various shapes and has strong compatibility. Natural gas or electric heating can be used, with an upper and lower double-layer heating design. The upper layer adopts (electric infrared radiation panel, gas catalytic infrared radiation panel), and the lower layer adopts (gas infrared radiation furnace, gas catalytic infrared radiation panel); the design process temperature is adjustable from 300 to 700°C; The equipment is mainly composed of a preheating conveyor line. Each sub-process, such as wire drawing, profiling, polishing, blowing, and assembly, is connected to both sides of the preheating conveyor furnace in a branch line manner, and a connection port is set. The wire tube after wire drawing is cleaned and dried through a chain conveying cleaning process and then transported to the blowing station. After production, the blowing employee places it on the preheating conveyor line for preheating and heating and then transports it to the next process. The profiling station is set on the side of the preheating conveyor line close to the polishing station. The semi-finished products after profiling are directly placed on the preheating conveyor line before cooling, eliminating the cooling process and saving time. After being transported to the polishing station, the polishing employee directly polishes, eliminating the preheating process again; after the blown semi-finished products and polished semi-finished products are transported to the assembly station, they are transported to the cache furnace for insulation through the horizontal conveying cache device for production, eliminating the process of manual transfer, cooling and preheating again; the assembled products return to the preheating conveyor line again for preheating or annealing, forming an assembly line production.

[0018] 1. Conveying system 1.1 Conveying method: Special heat-resistant stainless steel / ceramic roller / mesh belt conveyor is used. Due to the large differences in the specifications and appearances of the products produced at the same time, pallet-assisted conveying can be considered without affecting the heating of the products; 1.2 Conveying speed: 0-5m / min, each section of conveying speed is independently adjustable; 1.3 Conveyor line material: It can withstand long-term continuous operation without deformation under high temperature process conditions above 700℃; 1.4 Conveying function: In addition to the longitudinal conveying function, the line must also have a transverse conveying function to ensure that the products can be conveyed transversely to each workstation for production without affecting the continuous conveying of subsequent products, thereby achieving continuous and balanced production without affecting the subsequent material conveying of other processes.

[0019] 2. Line design: The whole line is divided into four processes: preheating + insulation process, polishing process, assembly process, and insulation annealing process. Each section is equipped with 6-8 operating stations.

[0020] 3. Workstation design: Each workstation is about 1.5 meters long, and the width (depth) of the workstation operating surface is about 60 cm; the working surface height is about 75 cm. The front end of the preheating / insulation process is reserved for the pressing process and the wire drawing material interface process to facilitate the subsequent process connection.

[0021] 4. Line speed design: The conveying speed is adjustable from 0 to 5 m / min (multi-line parallel design can be adopted).
