Description

Technical Field

[0001] This invention relates to the field of powder-liquid dual-chamber bag technology, and more specifically to a method for covering the powder chamber of a powder-liquid dual-chamber bag with an aluminum film. Background Technology

[0002] The powder chamber of the dual-chamber bag is treated with a welding machine that firmly welds the aluminum film to the powder chamber, ensuring a good seal and preventing air and moisture from entering through the weld gaps. The additive dispensing system can accurately dispense deoxidizers and desiccants between the bag body and the aluminum film, allowing them to function in the appropriate positions to maintain a dry and low-oxygen environment in the powder chamber, thereby ensuring powder quality.

[0003] In existing technology, additives (oxygen absorbers, desiccants) are manually applied to the powder chamber. A robot hangs the medicine bag on the bag-sorting mechanism and sends it to the bag-loading station of the aluminum film welding machine. A single roll of aluminum film passes through the film-loading mechanism, where continuous aluminum film is punched and cut. Four pieces of aluminum film are grouped together and sent to the aluminum film machine via the film transfer mechanism. The aluminum film is welded by upper and lower weak welding molds, and then the tail welding mold completes the tail welding. Afterward, the aluminum film chamber is filled with gas at the transfer and inflation station, followed by peripheral welding by the peripheral welding mold. Finally, cooling and punching are performed. Each process is coordinated in sequence to complete all the actions of the aluminum film welding machine.

[0004] Existing aluminum foil welding methods have the following problems; 1. Poor flatness of the aluminum foil after welding. Currently, aluminum foil is cooled naturally. Due to the lack of effective cooling control, uneven thermal stress is easily generated during the cooling process, which leads to deformation of the aluminum foil and affects the product's appearance quality and dimensional accuracy. 2. The additive dispensing process suffers from slow operation, and the dispensing machine lacks quality inspection functionality, making it impossible to monitor the quality of the dispensed materials in real time. Furthermore, the mechanical structure needs optimization, resulting in low equipment operating efficiency and difficulty in meeting production cycle requirements. 3. The need for dust removal and aluminum shavings removal was not fully considered during the design phase. Cardboard box scraps and aluminum foil shavings generated during the production process were not treated. This not only affects the welding quality of the aluminum foil, but also pollutes the production environment, affects the normal operation of equipment, and increases the risk of equipment failure. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention aims to provide a method for coating aluminum film in a powder-liquid dual-chamber bag, which solves the problem that the current aluminum film adopts natural cooling, which lacks effective cooling control methods, and is prone to uneven thermal stress during the cooling process, thus causing the aluminum film to deform and affecting the product's appearance quality and dimensional accuracy.

[0006] A method for covering the powder chamber of a dual-chamber powder-liquid bag with an aluminum film includes the following steps: The first step is to prepare the upper aluminum film and the lower aluminum film; The second step involves using an aluminum film clamping system to place the upper aluminum film, the powder-liquid dual-chamber bag, and the lower aluminum film into the lower aluminum film supply station, the upper bag station, and the upper aluminum film supply station of the welding cooling control system and power system, respectively. The third step involves welding the upper and lower aluminum films onto the powder-liquid dual-chamber bag using a welding cooling control system and a power system, and then cooling the weld between the upper and lower aluminum films.

[0007] Furthermore, in the first step, a lower aluminum film is prepared by a lower aluminum film preparation mechanism, and then an additive is applied to the aluminum film by an additive application mechanism. Next, a visual inspection and coding mechanism is used to print three phases on the lower aluminum film and check the effect of additive application and three-phase printing. An upper aluminum film is prepared by an upper aluminum film preparation mechanism.

[0008] Furthermore, in the third step, when welding the upper and lower aluminum films onto the powder-liquid dual-chamber bag using the welding cooling control system and power system, the upper and lower aluminum films are first weakly welded. After the weak welding, the top and bottom of the upper and lower aluminum films are welded and the weakly welded areas are cooled. Then, the periphery of the upper and lower aluminum films is welded and the weakly welded areas are cooled. Subsequently, the top, bottom, and periphery of the upper and lower aluminum films are cooled, and a bag hanging hole is punched at the bottom of the upper and lower aluminum films. Finally, the corners of the upper and lower aluminum films are welded to complete the aluminum film welding process.

[0009] Furthermore, in the third step, the lower aluminum film is weakly welded at the lower aluminum film weak welding station, and the upper aluminum film is weakly welded at the upper aluminum film weak welding station.

[0010] Furthermore, in the third step, the top and bottom of the upper aluminum film and the top and bottom of the lower aluminum film are welded at the top welding, tail welding and cooling stations. At the same time, the weak welded parts of the upper and lower aluminum films are cooled by the cooling plates set at the top welding, tail welding and cooling stations.

[0011] Furthermore, in the third step, after the welding of the aluminum film top welding, tail welding and cooling station is completed, helium is filled into the cavity between the upper aluminum film and the powder cavity of the powder-liquid dual-chamber bag through the helium filling station, and helium is filled into the cavity between the lower aluminum film and the powder cavity of the powder-liquid dual-chamber bag.

[0012] Furthermore, in the third step, the periphery of the upper aluminum film and the lower aluminum film are welded through the periphery welding and cooling station, while the weak welded parts of the upper aluminum film and the lower aluminum film are cooled by the cooling plate set on the periphery welding and cooling station.

[0013] Furthermore, in the third step, the welding area of ​​the aluminum film in the previous step is cooled by the cooling plate on the side welding cooling and punching station; and the bag hanging hole is punched out at the tail of the upper and lower aluminum films by the punch on the side welding cooling and punching station.

[0014] Furthermore, in the third step, after punching out the bag hanging hole, the powder-liquid dual-chamber bag is transferred to the corner welding station through the bag transfer station, and the corners of the upper aluminum film and the lower aluminum film are welded through the corner welding station.

[0015] Furthermore, in the third step, after the fillet welding is completed, the upper and lower aluminum films are cut and modified through the punching and finishing station.

[0016] Beneficial effects: Using a machine to weld the upper and lower aluminum films significantly improves the welding efficiency of the aluminum films compared to the natural cooling method used in existing technologies. The powder-liquid double-chamber bag is a qualified powder-liquid double-chamber bag prepared using the corresponding equipment in existing technologies. Attached Figure Description

[0025] A method for welding aluminum foil in a powder-liquid double-chamber bag, used as... Figures 1-5 The welding equipment shown is used, and the following steps are included: The first step is to prepare the upper aluminum film and the lower aluminum film; The second step involves placing the upper aluminum film, the powder-liquid dual-chamber bag, and the lower aluminum film into the lower aluminum film supply station 301, the upper bag station 302, and the upper aluminum film supply station 303 of the welding cooling control system and power system 3 via the aluminum film clamping system 2.

In this embodiment, the upper aluminum film preparation mechanism and the lower aluminum film preparation mechanism are existing technologies, which can easily and quickly prepare the desired aluminum film.

[0028] In the third step, when welding the upper and lower aluminum films onto the powder-liquid dual-chamber bag using the welding cooling control system and power system 3, the upper and lower aluminum films are first weakly welded.
