Description

Technical Field

[0001] The invention relates to the technical field of equipment and tooling, and in particular to a coating dipping device. Background Art

[0002] In the casting process, the surface treatment of sand cores is crucial, and the application of coatings is indispensable. The coating aims to achieve dual improvements: reducing the phenomenon of sand sticking to the castings to ensure a smooth and flawless surface; and enhancing the structural rigidity of the mold to effectively resist damage and deformation during transportation. At present, in order to achieve high-quality surface treatment, dip coating has become the mainstream method of sand core treatment due to its high efficiency and strong adaptability. Intelligent flow coating technology uses automated tools such as a carrier or an intelligent manipulator to deliver the sand core into a large dip coating box for coating. However, in this process, the uniformity and stability of the coating face challenges.

[0003] Although the circulating stirring system can prevent the coating from settling to a certain extent, the diaphragm pump is limited by the suction range and it is difficult to fully reach the sediment far away from the pipeline, resulting in coating stratification and uneven concentration. In addition, high-density media are easy to settle in the coating liquid, and the traditional circulation mechanism is difficult to effectively disperse these sediments. In addition, the high concentration of the coating can easily cause the pump body and pipeline to be blocked, affecting production efficiency and coating quality. Therefore, exploring more efficient coating stirring and circulation systems to ensure the uniformity and stability of the coating has become the key to improving the quality of casting processes.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] like Figure 1-Figure 3 As shown, an embodiment of the present invention discloses a coating dipping device, including a dipping mechanism 100 , wherein the dipping mechanism 100 further includes a dipping pool 110 , a moving mechanism 120 and a stirring mechanism 130 .

[0027] The dip coating pool 110 is the main part of the dip coating process and is used to contain the dip coating liquid, in which the workpiece is dip coated. The size and shape of the dip coating pool 110 can be designed according to actual needs to meet the dip coating needs of different workpieces.

[0028] The motion mechanism 120 includes a support member 121 and a first driving member 122. The support member 121 is a bearing member of the stirring mechanism 130 and is movably disposed on the dipping pool 110. In order to achieve smooth movement of the support member 121, guide rails can be arranged on the two outer sides of the dipping pool 110, and the two sides of the support member 121 can be connected to the guide rails through movable parts such as rollers and sliders. The second driving member can be used to drive the support member 121 to move on the guide rails to achieve movement of the stirring mechanism 130 in the length or width direction of the dipping pool 110.

[0029] One end of the stirring mechanism 130 is connected to the first driving member 122, and the other end is inserted into the inner cavity of the dipping pool 110 and extends along the bottom of the dipping pool 110. The stirring mechanism 130 can generally be composed of components such as stirring blades and a stirring shaft. Driven by the first driving member 122, the stirring mechanism 130 can rotate in the dipping pool 110 to stir the dipping liquid to prevent it from settling or stratifying. At the same time, due to the drive of the support member 121, the stirring mechanism 130 can also move in the dipping pool 110 to achieve comprehensive stirring of the dipping liquid in the entire dipping pool.

[0030] In the specific working process, before the dipping operation, the stirring mechanism 130 is first driven to rotate in the dipping tank 110 and move along the guide rail to fully stir the dipping liquid. After the stirring is completed, the stirring mechanism 130 can be moved to one end of the dipping tank 110 to reserve space for the workpiece dipping. Subsequently, the workpiece to be dipped is placed in the dipping tank 110 for dipping. During the whole process, the stirring mechanism 130 can be started again as needed to maintain the uniformity of the dipping liquid.

[0031] It can be seen from the above that in the paint dipping equipment disclosed in the embodiment of the present invention, the precipitation and stratification of the dipping liquid are effectively prevented by the rotation and movement stirring of the stirring mechanism 130, and the uniform distribution of the components of the dipping liquid is ensured, thereby improving the dipping efficiency and the uniformity of the coating. At the same time, when not stirring, the stirring mechanism 130 can be moved to one end of the dipping pool 110 to reserve space for the workpiece dipping, thereby realizing the rational use of the internal space of the dipping equipment. The paint dipping equipment of the present invention realizes the free movement of the stirring mechanism 130 in the dipping pool 110 through the design of the motion mechanism 120, and can be flexibly adjusted according to the size and shape of different dipping pools, thereby improving the flexibility of the equipment and its adaptability to different working environments.

[0032] In the embodiment disclosed in the present invention, the stirring mechanism 130 may include a connecting shaft 131 and a stirring blade 132 extending along the bottom of the dipping tank 110. The stirring blade 132 may be arranged on the connecting shaft 131, and the connecting shaft 131 may drive the stirring blade 132 to rotate. In this case, the stirring mechanism 130, through its unique structure and operation mode, shows significant technical effects in improving liquid uniformity, improving dipping efficiency, accelerating chemical reactions, reducing deposition and scaling, and improving operational flexibility.

[0033] Further, one end of the stirring blade 132 can be connected to the connecting shaft 131, and the other end of the stirring blade 132 can extend in a direction away from the connecting shaft 131. In the rotation direction of the connecting shaft 131, the front side of the stirring blade 132 can be tilted downward. Figure 3 Specifically, one end of the stirring blade 132 is connected to the connecting shaft 131, ensuring the effective transmission of the stirring power. The other end of the stirring blade 132 extends in a direction away from the connecting shaft 131. This design increases the sweeping area of ​​the blade, so that a wider liquid area can be covered during the stirring process.

[0034] More importantly, the front side of the stirring blade 132 is designed to be tilted downward in the direction of rotation of the connecting shaft 131. This tilted setting allows the front end of the blade to first contact and push the dipping liquid below when the stirring blade rotates. Due to the existence of the tilt angle, the dipping liquid is not only pushed horizontally when pushed by the blade, but also obtains an upward component force due to the tilt of the blade. In this way, the stirring blade can effectively stir the dipping liquid at the bottom upward and promote the vertical circulation of the liquid.

[0035] This beneficial effect is particularly important for the dip coating process. It ensures that the liquid in the dip coating tank can remain highly uniform, avoiding the precipitation and stratification of the liquid at the bottom, thereby improving the dip coating quality. At the same time, upward stirring can also help the gas dissolved in the liquid to escape, reducing the impact of bubbles on the dip coating effect. In addition, this stirring method can also promote chemical reactions, especially in those dip coating processes that require full mixing for the reaction to occur, and plays an irreplaceable role.

[0036] In an optional embodiment, there may be multiple stirring blades 132 , and the multiple stirring blades 132 may be evenly distributed along the axial direction of the connecting shaft 131 , thereby better ensuring the stirring effect.

[0037] Furthermore, a plurality of stirring blades 132 can be sleeved on the connecting shaft 131 through a sleeve 133, and a plurality of stirring blades 132 can constitute a blade assembly, and a plurality of blade assemblies can be arranged at intervals in the length direction of the connecting shaft 131. At this time, this design allows a plurality of stirring blades 132 to be flexibly installed on the connecting shaft 131, and the stirring blades 132 are sleeved on the connecting shaft 131 through a sleeve 133, which is convenient for installation and disassembly, and also convenient for adjusting the number and position of the blades according to different stirring requirements. By combining a plurality of stirring blades 132 into a blade assembly, and arranging a plurality of such assemblies at intervals in the length direction of the connecting shaft, the contact area between the stirring mechanism 130 and the dipping liquid can be greatly increased.

[0038] The increase in stirring area means that more liquid can be stirred at the same time, which helps to accelerate the mixing and circulation of the liquid and promote the uniform distribution of the liquid. In the dip coating process, a uniform liquid environment is the key to ensuring the quality of the dip coating. Therefore, this design can effectively improve the stirring effect, so that the dip coating liquid can achieve higher uniformity in the dip coating tank, and reduce the occurrence of adverse phenomena such as stratification and precipitation.

[0039] In the embodiment of the present invention, the number of the first driving member 122 and the stirring mechanism 130 can be multiple, and the multiple first driving members 122 can be arranged on the support member 121 at intervals, and each first driving member 122 is connected to a corresponding stirring mechanism 130. At this time, the multiple stirring mechanisms 130 work simultaneously, which greatly increases the total area and speed of stirring, so that the dipping liquid can reach a uniform state in a shorter time. Comprehensive coverage stirring reduces the stirring blind area, avoids the retention and stratification of liquid in certain areas of the pool, and ensures the uniformity of the liquid in the entire pool.

[0040] Furthermore, when combined with the function of forward and backward movement (such as achieved by the movement of the support member 121 on the guide rail), the stirring mechanism 130 can further achieve stirring of different depths and regions of the dipping pool, meeting more complex stirring requirements. Moreover, this design enables the stirring mechanism to adapt to dipping pools of different sizes and shapes, thereby improving the versatility and flexibility of the device.

[0041] In an optional embodiment, the dipping mechanism 100 may further include a salvage frame 140, which is movably disposed in the dipping pool 110, and when the stirring mechanism 130 is working, the salvage frame 140 may be located at the bottom of the stirring mechanism 130. The introduction of the salvage frame 140 brings many beneficial effects to the dipping mechanism 100, including effectively removing coagulated materials, improving stirring efficiency, ensuring process continuity, and enhancing equipment versatility.

[0042] The coating dipping equipment disclosed in the embodiment of the present invention may further include a stirring tank 200, wherein the top and bottom of the stirring tank 200 may be provided with a first liquid material inlet 210 and a first liquid material outlet 220, respectively, and the top and bottom of the dipping pool 110 may be provided with a second liquid material outlet 150 and a second liquid material inlet 160, respectively, wherein the first liquid material inlet 210 may be connected to the second liquid material outlet 150, and the first liquid material outlet 220 may be connected to the second liquid material inlet 160. Specifically, the top of the stirring tank 200 is provided with a first liquid material inlet 210, and the bottom is provided with a first liquid material outlet 220, while the top and bottom of the dipping pool 110 are provided with a second liquid material outlet 150 and a second liquid material inlet 160, respectively. Such a design enables a closed-loop liquid circulation system to be formed between the two.

[0043] During the dipping process, as the workpiece is immersed in and taken out, the liquid level in the dipping pool 110 changes. When the liquid level rises to a certain level, the excess dipping liquid automatically flows into the stirring tank 200 through the second liquid material outlet 150. In the stirring tank 200, the dipping liquid can be further stirred and mixed to ensure that the components therein are more uniform, and it also helps to remove bubbles and dissolved gases.

[0044] After the stirring, the coating liquid flows back to the coating tank 110 through the first liquid outlet 220 and the second liquid inlet 160 to continue the coating operation. This circulation process not only ensures the freshness and uniformity of the coating liquid, but also effectively avoids the problem of liquid overflow caused by excessive liquid level, thereby improving production efficiency and resource utilization.

[0045] In addition, this design also enhances the flexibility of the dip coating process. By adjusting the stirring parameters (such as stirring speed, stirring time, etc.) of the stirring tank 200, the performance of the dip coating liquid can be further optimized to meet the requirements of different dip coating processes.

[0046] Furthermore, the coating dipping device disclosed in the embodiment of the present invention may further include a liquid material pump 300, and the liquid material pump 300 may be connected between the first liquid material outlet 220 and the second liquid material inlet 160. At this time, the introduction of the liquid material pump 300 further enhances the power and efficiency of the liquid circulation between the stirring tank 200 and the dipping mechanism 100, and provides strong support for the stability and efficiency improvement of the dipping process.

[0047] In an optional embodiment, the second liquid material outlet 150 may be higher than the first liquid material inlet 210. In this case, the second liquid material outlet 150 is designed to be higher than the first liquid material inlet 210, which not only promotes the natural flow of the dipping liquid and improves the efficiency and stability of the liquid circulation, but also helps to reduce the mixing of bubbles and impurities and improve the response speed of the liquid circulation. These beneficial effects jointly improve the overall performance and reliability of the dipping process.

[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
