Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder coating drying technology, specifically to a powder coating drying device. Background Technology
[0002] In the powder coating drying process, ensuring uniform curing of the coating is crucial. Existing powder coating drying equipment, such as the one disclosed in utility model patent CN219898947U, achieves the rotation and movement of powder-coated parts during the drying process by setting up components such as slide rails, sliding plates, connecting rods, and hooks inside the drying chamber. This promotes full contact between hot air and the surface of the parts, thereby improving drying efficiency. This design improves the drying effect to a certain extent, but it still has some shortcomings.
[0003] Specifically, when metal parts are placed on the slide rails for drying and curing, the close proximity between the bottom of the metal parts and the bottom of the cabinet leads to uneven heating on the side closest to the bottom of the cabinet, especially in multi-sided powder coating. This uneven heating can affect the curing effect after powder coating, thus reducing product quality. Therefore, it is necessary to improve and optimize this existing technology to address this deficiency. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-3 This application proposes a powder coating drying device, including a cabinet 1 with a front opening, the front of which is connected to a cabinet door 11 via hinges. Inside the cabinet 1 is a unique U-shaped support frame 2, designed to allow its downward side walls to slide against the upper and lower side walls of the cabinet 1, respectively, so that the U-shaped support frame 2 can be fully pulled out of the cabinet 1 for operation when needed.
[0022] The inner side of the U-shaped support frame 2 is designed with a special suspension assembly 3 for hanging the parts to be powder coated. According to the description in the claim, the suspension assembly 3 includes a plurality of hooks 31 fixed to the top of the U-shaped support frame 2, which are arranged sequentially from front to back to hang a plurality of powder coated parts.
[0023] To further improve hanging efficiency and uniform heating, the lower ends of adjacent hooks 31 are arranged in opposite directions, forming a staggered arrangement. This design not only optimizes space utilization but also ensures that each powder-coated part receives sufficient heating and curing.
[0024] The end of the hook 31 is also provided with at least two hook branches 32, and the ends of the hook branches 32 are inclined upwards. This detailed design helps to better hang and stabilize the powder-coated parts, while ensuring that they do not interfere with or come into contact with each other during the heating process.
[0025] To achieve uniform heating and curing, a fan 4 is installed at the top inside the cabinet 1 to introduce outside air into the cabinet 1. At the same time, gas heating and guiding structures 5 are provided on the left and right side walls inside the cabinet 1 at the suspension components 3 corresponding to the inside of the U-shaped support frame 2.
[0026] The heating and flow guiding structure 5 specifically includes a first flow guiding cavity 51 opened in the top of the cabinet 1, and flow guiding plates 54 respectively provided on the left and right side walls corresponding to the first flow guiding cavity 51. A second flow guiding cavity 52 communicating with the first flow guiding cavity 51 is further opened inside the flow guiding plate 54, and an electric heating wire 53 is provided in the first flow guiding cavity 51 corresponding to the second flow guiding cavity 52.
[0027] This design allows the external air introduced by the fan 4 to be heated by the electric heating wire 53 and then evenly distributed to each powder-coated part inside the U-shaped support frame 2 via the guide plate 54. To enhance the heating effect, the second guide chamber 52 of the two guide plates 54 is also evenly provided with multiple guide holes 55 on one side of the cabinet 1, so that the hot air can cover each powder-coated part more finely and evenly.
[0028] To facilitate operation and maintenance, limiting grooves 12 are respectively provided on the upper and lower side walls of the cabinet 1 at the locations corresponding to the U-shaped support frame 2. The U-shaped support frame 2 is provided with limiting sliders 21 that can slide within the limiting grooves 12. This sliding design allows the U-shaped support frame 2 to move freely within the cabinet 1, making it easy to hang the powder-coated parts in the optimal position for heat curing.
[0029] In addition, a handle 22 is provided on the lower side of the end of the U-shaped support frame 2 facing the opening of the cabinet 1. With this handle 22, the operator can more easily pull the entire U-shaped support frame 2 out of the cabinet 1 for hanging and retrieving operations.
[0030] In summary, the powder coating drying equipment provided in this embodiment has advantages such as compact structure, simple operation, and uniform heating. It can meet the heating and curing requirements of powder-coated parts of different sizes and shapes, ensuring that each part receives sufficient and uniform heating treatment. At the same time, the maintainability and operability of the equipment have also been fully considered and optimized.
