Description

Technical Field

[0001] This utility model relates to the technical field of paint-baking door production equipment, and more specifically, to a paint-baking device for paint-baking doors. Background Technology

[0002] In the production process of painted doors, the painting process has a crucial impact on the quality and appearance of the final product. However, traditional painting equipment has revealed a series of problems that urgently need to be solved in actual production applications, which seriously restrict the production efficiency and quality improvement of painted doors.

[0003] Traditional workpiece conveying methods in baking paint systems have several drawbacks. Firstly, many systems rely on manual workpiece handling, which significantly increases worker workload. Furthermore, the inherent uncertainty of human operation during handling can easily lead to workpiece collisions and surface scratches, damaging the workpiece surface before baking paint and affecting the final paint quality. Secondly, even when mechanical conveying methods are used, they are mostly simple linear conveying. This method cannot achieve continuous and efficient production. Jams and stoppages can occur during conveying, making it difficult to improve production efficiency and meet the growing market demand for large-scale production of painted doors.

[0004] In terms of workpiece clamping and fixing, traditional clamping mechanisms are often rudimentary in design. They typically struggle to adapt flexibly to paint thicknesses of doors. When faced with production tasks involving multiple specifications, operators must frequently change clamps or perform complex adjustments. This not only consumes a significant amount of time and reduces production efficiency, but improper operation during adjustments can also lead to clamping instability. Unstable clamping causes workpiece movement during the painting process, resulting in uneven paint application and serious problems such as runs and orange peel texture, severely impacting product appearance and quality, and directly reducing product yield.

[0005] Environmental control within the paint baking chamber is also a weak point of traditional systems. For example, poor air circulation is a common problem, leading to uneven temperature and humidity distribution within the chamber. This unevenness negatively impacts the curing effect of the paint, preventing some areas from fully curing and affecting the hardness, wear resistance, and other properties of the painted doors. Furthermore, traditional systems often fail to adequately treat exhaust gases, directly releasing harmful gases into the environment, polluting the surrounding area and endangering the health of on-site operators.

Detailed Implementation

[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] like Figures 1-4 The painting device for painted doors shown is organically composed of three main parts: a painting chamber unit, a suspended conveyor assembly, and a painting operation unit.

[0035] Paint booth unit:

[0036] Cavity and track: The paint baking chamber unit is equipped with a sealed cavity 101, which creates a relatively independent and stable spatial environment for the paint baking operation, effectively reducing the interference of external environmental factors on the paint baking process and ensuring the stability of paint baking quality.

[0037] The continuous circulating track system 102, which runs through the inside and outside of the sealed cavity 101, is the key to the efficient conveying of the entire device. The track system 102 is composed of an internal conveying section 102a located inside the cavity and an external conveying section 102b extending outside the cavity. The internal conveying section 102a and the external conveying section 102b form a closed loop. This design enables the workpiece to be continuously conveyed inside and outside the baking room, providing strong support for automated and continuous production.

[0038] Specifically, the track system 102 adopts a closed-loop power track design. The multi-layered horizontally folding internal conveying section 102a is stably suspended from the top of the cavity by means of a fixed bracket 102c. The multi-layered horizontally folding layout cleverly utilizes the limited space inside the paint baking chamber, effectively extending the conveying path and dwell time of the workpiece in the paint baking chamber, creating favorable conditions for fully completing the paint baking operation. The U-shaped extended external conveying section 102b is precisely connected at both ends to the inlet and outlet ends of the internal conveying section 102a, greatly facilitating the entry and exit of workpieces in and out of the paint baking chamber and ensuring the smoothness of the production process. At the same time, the drive motor drives the suspension assembly 103 to move at a uniform speed along the track system 102 through a gear chain transmission mechanism, ensuring the stability and accuracy of the conveying process and avoiding adverse effects on the paint baking quality due to unstable conveying speed.

[0039] It should be noted that the drive motor drives the suspension components through a gear and chain transmission mechanism, which is a mature existing drive structure and will not be elaborated on here.

[0040] Gas Circulation and Inlet / Outlet: The paint booth unit is also equipped with a gas circulation system, which includes a ground air inlet 301a at the bottom of the chamber and an exhaust outlet 301b at the top. The ground air inlet 301a is connected to the air supply device, and the top exhaust outlet 301b is connected to the air extraction device. The working principle of the gas circulation system is to send fresh air into the chamber through the air supply device from the air inlet at the bottom of the chamber, so that the air flows from bottom to top in the chamber and is then discharged from the top exhaust outlet. This air circulation method can effectively ensure the uniform distribution of temperature and humidity in the paint booth, providing a stable and suitable environment for the paint baking operation, thereby significantly improving the consistency and quality of the paint baking. In addition, the paint booth unit has two unit inlets / outlets 105 on the side, and a unit door 106 with a sliding switch is installed at the inlet / outlet 105. The unit inlets / outlets and unit doors facilitate the installation, debugging and maintenance of the equipment. At the same time, when necessary, such as when the equipment is being repaired or large workpieces are being moved in or out, the unit doors can be opened to provide sufficient operating space.

[0041] Suspended Conveying Assembly: The suspended conveying assembly consists of multiple suspended assemblies 103 that circulate along the track system 102. Each suspended assembly 103 is equipped with a detachable workpiece clamping mechanism 104. The arrangement of multiple suspended assemblies allows the device to transport multiple workpieces simultaneously, significantly improving production efficiency. The detachable workpiece clamping mechanism is flexibly designed and can be quickly replaced or adjusted according to different production needs to adapt to diverse production tasks. The workpiece clamping mechanism 104 specifically includes a frame body 104a. An upper fixed clamping plate 104b and a lower movable clamping plate 104c are arranged opposite each other on the inner side of the frame body 104a. The lower movable clamping plate 104c is connected to the frame body 104a through an elastic adjustment assembly 104d. The elastic adjustment assembly 104d gives the lower movable clamping plate 104c the ability to elastically displace in the vertical direction, so that the workpiece clamping mechanism 104 can easily adapt to workpieces of different thicknesses, greatly improving the versatility and adaptability of the workpiece clamping mechanism 104.

[0042] like Figure 4 As shown, the elastic adjustment component 104d consists of a spring 104d-1 and a slide rod 104d-2. The slide rod 104d-2 is slidably engaged with the frame body 104a. The spring 104d-1 is mounted on the slide rod 104d-2, and the elastic force is used to realize the adaptation function of the mechanism.

[0043] Furthermore, the clamping surfaces of the upper fixed clamping plate 104b and the lower movable clamping plate 104c are specially provided with slots 104e. The presence of the slots effectively increases the friction between the clamping plates and the workpiece, ensuring that the workpiece can be firmly clamped during the conveying and painting process, avoiding shaking, and effectively guaranteeing the quality of the painting.

[0044] Paint Baking Unit: The core of the paint baking unit is the curing modules 202 located within the paint baking chamber. These curing modules 202 are spaced apart along the extension direction of the internal conveying section 102a. This spaced distribution allows the workpiece to pass through each curing module sequentially during the track transport process, achieving a gradual and uniform curing process. This helps improve the curing effect and quality stability. The curing modules 202 use hot air heating equipment, which has a heating unit inside. When the heating unit is working, it heats the air and then delivers the heated air outward through the hot air outlet to heat and cure the workpieces passing through. Hot air heating ensures uniform heating of the paint, avoiding localized overheating or undercooling, thereby effectively improving the curing quality and ensuring that the various performance indicators of the painted door reach a high level.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
