Description

Technical Field

[0001] This utility model relates to the field of automated processing technology for thermos cups, specifically to an automated drying device for containers. Background Technology

[0002] The production process of insulated cups includes two stages: "water expansion" and "cup separation." "Water expansion" is a metal forming process where high-pressure water is injected into a mold to cause a metal sheet (usually stainless steel) to expand and conform to the inner wall of the mold, forming the curved or irregularly shaped structure of the cup. In short, it involves filling a steel tube with water to stretch the material into the desired shape. "Cup separation" refers to the process of cutting and separating multiple connected outer shells produced simultaneously in a single water expansion process into independent units. Except for stamped insulated cups, the processing of other cups generally requires a water expansion process followed by a cup separation process, such as laser cup separation.

[0003] After hydroforming, the inner and outer surfaces of the semi-finished product will be covered with a large amount of process water (or oil-water mixture) and lubricant residue. If these residual liquids are not effectively removed, the processing quality of subsequent processes (such as cup splitting, welding, polishing, etc.) will decline, and the product defect rate will increase; residual liquid entering the equipment may also cause equipment corrosion, malfunction, or even damage. Therefore, existing technologies perform water / liquid removal treatment on the semi-finished product after the hydroforming process, but a series of problems exist, such as:

[0004] (1) The semi-finished product after swelling is placed in a material box to drain naturally. After the liquid has drained, it is transferred to the subsequent production line. This method is inefficient, has a long processing cycle, and cannot be effectively connected with the continuous production line, resulting in interruption of the production process.

[0005] (2) A long drying tunnel is added after the water-blowing process to quickly dry the liquid on the semi-finished product using heat drying. However, the heating process accelerates the release of stress inside the cup blank (after undergoing high-pressure plastic deformation), which can easily lead to uncontrollable dimensional deviations or shape distortions. The liquid used in water-blowing often contains impurities (metal particles, oil stains, etc.). After drying, these residues form dirt that can create stains, streaks, or spots on the inner wall of the semi-finished product. Large drying tunnels occupy a large area and have high energy consumption due to continuous heating, significantly increasing operating costs.

[0006] Therefore, there is an urgent need to provide an automated container drying device to solve the above-mentioned technical problems. Summary of the Invention

[0007] In response to the problems in related technologies, this utility model proposes an automated drying device for containers, which can improve the production efficiency of containers such as thermos cups, reduce production costs, and solve the problem of unstable product quality.

[0008] This utility model is implemented as follows:

[0009] An automated drying device for containers, used to dry cups, the cups having openings at both the top and bottom; characterized in that it includes a rotating module, a lifting module, and an air blowing module;

[0010] The rotating module is provided with multiple cup molds arranged in a circular array, and the cup molds are used to vertically place the cups; the lifting module is fixedly connected or driven to the blowing module, and is used to make the blowing module rise and fall;

[0011] The air blowing module includes one or more blowing rod assemblies; one of the blowing rod assemblies includes an inner blowing rod and an outer blowing rod, both of which have air outlets at their lower ends; the blowing rod assembly is connected to an air source, such as an air compressor.

[0012] When the blowing module descends, for one of the blowing rod assemblies, the lower end of the inner blowing rod gradually extends downward into the upper opening of the cup, the air outlet of the inner blowing rod faces the inner wall of the cup, and the air outlet of the outer blowing rod faces the outer wall of the cup.

[0013] The "cup" mentioned above refers to the cup that has just undergone the "water swelling" process.

[0014] The rotating module is used to sequentially transfer cups to the area below the blower module to complete the blowing / blowering operation. When the blowing module is at the top and not fluctuating, the rotating module rotates at a fixed angle and time interval; when the blowing module rises or falls, the rotating module stops rotating; the air source provides high-pressure gas to the blowing module, and the high-pressure gas is ejected from the air outlet, thereby "blowing" the liquid on the inner and outer walls of the cup downwards, realizing the automation of the cup drying process.

[0015] Compared to manual processing, it is more efficient; compared to long drying tunnels, it can effectively remove stains and impurities, and it takes up less space, consumes less energy, and has lower costs.

[0016] Using robotic arms and other equipment, cups on the rotating module can be replaced, that is, cups that have been "swelled with water" can be loaded and cups that have been "blown with air" can be unloaded, completing the drying process and integrating the production line into the entire automated cup production process.

[0027] Installing sealing rings, clamping parts, and waterproof covers can prevent liquids from seeping into the motor below through gaps in the connection points, thus preventing damage to the equipment.

[0028] As a further optimization of the above solution, the lifting module includes a drive unit, a lifting platform, and multiple vertical and parallel guide rods; the guide rods pass through the lifting platform; the lifting platform extends horizontally toward the rotating module to form an extension; the air blowing module is fixedly installed at the extension;

[0029] The drive unit is connected to the lifting platform via a transmission.

[0030] The drive unit moves the lifting platform up and down.

[0031] Furthermore, a linear bearing is provided between the guide rod and the lifting platform, and the linear bearing is fixedly connected to the lifting platform, which can reduce the resistance during relative displacement.

[0032] As a further optimization of the above solution, the drive unit is an electric cylinder or a pneumatic cylinder; the drive unit has a free end; the drive unit is fixedly located directly below the lifting platform and between multiple guide rods; the top of the free end is fixedly connected to the lifting platform.

[0033] As a further optimization of the above solution, in a blow rod assembly, there are multiple outer blow rods, which are arranged around the outer periphery of the inner blow rod;

[0034] The air outlet of the outer blow rod is obliquely directed toward the inner blow rod, or obliquely directed toward the downward extension direction of the inner blow rod;

[0035] The bottom of the internal blow rod has a side opening, forming an air outlet.

[0036] As a further optimization of the above solution, a blower head is installed at the bottom end of the outer blower rod and the bottom end of the inner blower rod, respectively, and the air outlet is located on the blower head.

[0037] The blow nozzle is replaceable and can be easily customized in shape, size, and opening position to fit cups of different sizes. The blow nozzle can also be replaced with a bamboo-joint tube on the external blow rod.

[0038] Furthermore, the cup mold has a cylindrical structure, and its inner wall is provided with limiting steps. The cup can be placed and fixed on the limiting steps. Furthermore, the limiting steps are multi-layered, with each layer forming a limiting cavity; the radial dimension of each limiting cavity gradually increases from bottom to top. Different limiting cavities can accommodate cups of different sizes.
