Description

Technical Field

[0001] This utility model relates to the field of coating drying technology, and in particular to a polymer coating drying structure. Background Technology

[0002] In the field of mechanical parts manufacturing, the application of polymer coatings is becoming increasingly widespread, and the drying process is crucial. Traditional drying methods, such as natural drying, are time-consuming and inefficient, making it difficult to meet the needs of large-scale production. While hot air drying can speed up the process, it may lead to uneven heating of the coating, resulting in problems such as cracking and deformation, which affect the precision and performance of mechanical parts. At the same time, some drying methods consume a lot of energy, increasing production costs. With the advancement of Industry 4.0, the requirements for the quality and production efficiency of mechanical parts are constantly increasing. Developing efficient, energy-saving drying technologies that can guarantee coating quality is urgently needed. This will not only help improve product quality but also enhance the competitiveness of enterprises in the market.

[0003] In the existing technology, the metal plate is in a static state during the drying process, which leads to a slow drying speed and low efficiency of the metal coating on the surface of the metal plate, requiring a lot of time.

[0004] To address the aforementioned issues, an existing patent (publication number: CN219073485U) proposes a polymer coating drying structure. This structure utilizes an auxiliary device including a first gear. A groove is formed on the inner bottom surface of the drying chamber, and a slide bar is slidably connected inside the groove. A first rack is fixedly installed at the end of the slide bar away from the groove. A strip plate is fixedly installed on the inner bottom surface of the drying chamber, and a groove is formed on the side of the strip plate. An L-shaped plate is slidably connected inside the groove. A connecting rod is fixedly installed on the vertical end surface of the L-shaped plate. A second motor is fixedly installed on the end surface of the L-shaped plate away from the connecting rod. A second gear is fixedly installed at the output end of the second motor, and a second rack is fixedly installed on the surface of the strip plate. This invention solves the problem that in existing metal coating drying devices, the metal plate remains stationary throughout the entire drying process, leading to slow drying speed, low efficiency, and a significant time consumption for the metal coating on the metal plate surface.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, in terms of improving drying efficiency, the examples mentioned above only achieve the effect of intervention on the metal plate without any intervention on the material itself. This leaves considerable room for improvement in the drying efficiency of polymer coatings. Furthermore, a significant amount of heat energy is generated during the drying process, and current drying equipment typically does not prioritize heat recovery, resulting in resource waste.

[0006] To address this, a polymer coating drying structure is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a polymer coating drying structure that can solve the problems of existing drying efficiency still being significantly improved and significant waste of heat resources.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a polymer coating drying structure, including a drying barrel, a discharge port fixedly connected to the front side of the drying barrel, a feed port fixedly connected to the rear side of the drying barrel, a dynamic drying mechanism on both the inner and outer sides of the drying barrel, and a heat recovery mechanism on the inner side of the drying barrel.

[0009] The dynamic drying mechanism includes a gear ring, a drive gear, a main shaft, a stirring plate, and a reciprocating oscillating assembly. The gear ring is fixedly connected to the rear side of the discharge port and to the outside of the drying barrel. The drive gear is meshed with the outside of the gear ring. The main shaft is movably connected to the inside of the drying barrel. The reciprocating oscillating assembly is movably connected to the outside of the main shaft, and the stirring plate is movably connected to the inside of the reciprocating oscillating assembly.

[0010] Preferably, the heat recovery mechanism includes an extension tube, a thermally conductive metal outer shell, a heat capacity transition chamber, a thermally conductive metal inner cavity, and a heat recovery unit.

[0011] Preferably, the extension tube is fixedly connected to the outside of the drying barrel, and the heat-conducting metal shell is fixedly connected to the outside of the extension tube.

[0012] Preferably, the heat capacity transition chamber is movably connected to the inner side of the thermally conductive metal shell, the thermally conductive metal inner cavity is movably connected to the inner side of the thermally conductive metal shell, and the heat recovery device is movably connected to the inner side of the thermally conductive metal inner cavity.

[0013] Preferably, the reciprocating swing assembly includes a support arm, a connecting block, and a hydraulic rod.

[0014] Preferably, the support arm is rotatably connected to the outside of the main shaft, the stirring plate is rotatably connected to the outside of the support arm, the linkage block is fixedly connected to the outside of the support arm, the hydraulic rod is rotatably connected to the outside of the linkage block, and the hydraulic rod is rotatably connected to the outside of the main shaft.

[0015] Preferably, a support frame is fixedly connected to the bottom of the outer side of the drying barrel, and the drive gear is fixedly connected to the top of the support frame.

[0016] Preferably, both the inlet and outlet are movably connected to sensing valves.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a dynamic drying mechanism, utilizes the cooperation of the drive gear and gear ring to make the drying drum roll as a whole on the support base, causing the internal mechanical polymer-coated parts to roll accordingly. This expands the contact area between the polymer-coated parts and the hot air. At the same time, the main shaft drive motor is started to drive the support arm and the stirring plate. The stirring plate turns the polymer-coated parts like a waterwheel. In addition, the reciprocating extension and retraction of the hydraulic rod on the outside of the main shaft pulls the support arm to swing up and down, like stir-frying, which greatly increases the movement and turning of the material. Through the all-round and multi-angle active intervention of the material, the drying environment of the material is changed, allowing the material to be heated and ventilated evenly in all directions during the dynamic process of rolling, turning and stir-frying. This effectively makes up for the defects of traditional methods, greatly promotes the drying efficiency of polymer-coated parts, and avoids coating dripping and accumulation.

[0019] 2. This application, by setting up a heat recovery mechanism, cleverly directs some of the heat inside the drying drum to the heat-conducting metal outer shell through an extension tube installed on the outside of the drying drum. Using water as a heat-conducting medium with high specific heat capacity, the heat is transferred to the heat-conducting metal inner cavity, where it is absorbed by the collection tube of the heat recovery device and transferred outward. This achieves effective heat recovery and reuse, such as for preheating the inside of the drying drum during startup. Compared to directly using heat recovery equipment, it does not require an additional, complex recovery device. Instead, it utilizes the drying drum's own structure to combine the heat transfer process with the existing components of the equipment, greatly reducing costs and equipment complexity. Without affecting drying efficiency, it significantly improves energy utilization and reduces resource waste. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A polymer coating drying structure includes a drying barrel 1, a discharge port 2 fixedly connected to the front side of the drying barrel 1, a feed port 3 fixedly connected to the rear side of the drying barrel 1, a dynamic drying mechanism 4 on both the inner and outer sides of the drying barrel 1, and a heat recovery mechanism 5 on the inner side of the drying barrel 1.

[0029] The dynamic drying mechanism 4 includes a gear ring 41, a drive gear 42, a main shaft 43, a stirring plate 44, and a reciprocating oscillating assembly 45. The gear ring 41 is fixedly connected to the rear side of the discharge port 2 and the outer side of the drying barrel 1. The drive gear 42 is meshed with the outer side of the gear ring 41. The main shaft 43 is movably connected to the inner side of the drying barrel 1. The reciprocating oscillating assembly 45 is movably connected to the outer side of the main shaft 43, and the stirring plate 44 is movably connected to the inner side of the reciprocating oscillating assembly 45.

[0030] In this embodiment: the drive gear 42 can drive the gear ring 41 to rotate, thereby causing the entire drying barrel 1 to roll and the internal dried material to roll. The rotation of the main shaft 43 inside the drying barrel 1 drives the stirring plate 44 to rotate, which can scoop up and stir the material to achieve a turning effect. The reciprocating swing component 45 drives the stirring plate 44 to produce a stir-fry-like effect on the workpiece, so that the workpiece can be heated and ventilated evenly from all directions, avoiding coating dripping and accumulation.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5As shown, the heat recovery mechanism 5 includes an extension tube 51, a heat-conducting metal outer shell 52, a heat capacity transition chamber 53, a heat-conducting metal inner cavity 54, and a heat recovery unit 55.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the extension tube 51 is fixedly connected to the outside of the drying barrel 1, and the heat-conducting metal shell 52 is fixedly connected to the outside of the extension tube 51.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the heat capacity transition chamber 53 is movably connected to the inner side of the heat-conducting metal outer shell 52, the heat-conducting metal inner cavity 54 is movably connected to the inner side of the heat-conducting metal outer shell 52, and the heat energy recovery unit 55 is movably connected to the inner side of the heat-conducting metal inner cavity 54.

[0034] In this embodiment: By providing an extension tube 51 on the outside of the drying barrel 1, some of the heat inside the barrel can be directed to the heat-conducting metal shell 52. After the heat is absorbed by the heat-conducting metal shell 52, it is introduced into the heat capacity transition chamber 53 with water as the heat-conducting medium. Then, the heat is transferred to the heat-conducting metal inner cavity 54 on the inside through the heat-conducting medium. The heat recovery device 55, which is attached to the heat-conducting metal inner cavity 54, absorbs the heat and transfers it outward, realizing the recovery and reuse of heat energy, such as for preheating inside the barrel when the drying barrel 1 is started.

[0035] Specifically, such as Figure 3 , Figure 4 As shown, the reciprocating swing assembly 45 includes a support arm 45a, a linkage block 45b, and a hydraulic rod 45c.

[0036] Specifically, such as Figure 3 , Figure 4 As shown, the support arm 45a is rotatably connected to the outside of the main shaft 43, the stirring plate 44 is rotatably connected to the outside of the support arm 45a, the linkage block 45b is fixedly connected to the outside of the support arm 45a, the hydraulic rod 45c is rotatably connected to the outside of the linkage block 45b, and the hydraulic rod 45c is rotatably connected to the outside of the main shaft 43.

[0037] In this embodiment: the rotation of the main shaft 43 drives the rotation of multiple sets of support arms 45a on the outside, and the support arms 45a in turn drive the rotating of the agitator plate 44. Since the agitator plate 44 is rotatably connected to the support arms 45a, when it comes into contact with the mechanical parts, the agitator plate 44 will rotate like a waterwheel, turning the parts over. At the same time, the hydraulic rod 45c on the outside of the main shaft 43 performs reciprocating extension and retraction motion. The connecting block 45b at the other end of the hydraulic rod 45c pulls the support arm 45a up and down, so that the internal mechanical parts are in a state similar to being stir-fried.

[0038] Specifically, such as Figure 1, Figure 2 As shown, a support frame 6 is fixedly connected to the bottom of the outer side of the drying barrel 1, and a drive gear 42 is fixedly connected to the top of the support frame 6.

[0039] Specifically, such as Figure 1 , Figure 2 As shown, induction valves 7 are movably connected to the inner sides of both the inlet 3 and the outlet 2.

[0040] In this embodiment: the drying barrel 1 and the drive gear 42 can be supported by the support base 6, and the sealing state of the drying barrel 1 and the closing state of the inlet 3 and the outlet 2 can be controlled by the sensing valve 7.

[0041] Working principle: After the polymer coating is applied to the mechanical parts, the metal parts requiring surface drying are fed into the drying barrel 1 through the feed inlet 3 via a transfer structure. After feeding, the drying barrel 1 is kept sealed by closing the induction valve 7, and the heating structure on the inner wall of the drying barrel 1 is activated to raise the temperature of the inner wall, achieving the drying effect. During this process, the drive gear 42 drives the gear ring 41 meshing with it to rotate. The gear ring 41 is fixedly connected to the drying barrel 1 and the discharge port 2, thereby making the entire... The drying drum 1 rotates as a whole under the support of the base frame 6, causing the internal mechanical parts to rotate for drying. Simultaneously, the drive motor of the main shaft 43 is activated. The drive motor of the main shaft 43 is located at one end of the inlet 3. The rotation of the main shaft 43 drives the multiple sets of support arms 45a on its outer side to rotate, which in turn drives the agitator plate 44 it carries to rotate. Since the agitator plate 44 is rotatably connected to the support arms 45a, when it rotates and contacts the mechanical parts, it rotates like a waterwheel, turning the mechanical parts over. During this process… Simultaneously, the hydraulic rod 45c on the outer side of the main shaft 43 reciprocates, allowing the supporting arm 45a to swing up and down via the connecting block 45b at the other end of the hydraulic rod 45c. This creates a stir-fry-like effect on the internal mechanical parts, ensuring comprehensive heating and ventilation during the drying process of the polymer-coated parts, promoting drying efficiency, and preventing coating sagging and accumulation. Furthermore, an extension tube 51 is installed on the outer side of the drying barrel 1 to guide some of the heat inside the drying barrel 1 into contact with the heat-conducting metal outer shell 52, thus ensuring proper heat conduction. After absorbing heat, the hot metal outer shell 52 is introduced into the heat-conducting medium inside the heat capacity transition chamber 53. Generally, water with a large specific heat capacity is used. Then, the heat is transferred to the inner heat-conducting metal cavity 54 through the heat-conducting medium. This allows the collection pipe of the heat energy recovery device 55, which is in contact with the heat-conducting metal cavity 54, to absorb heat and transfer it outward. This enables the recovery and reuse of heat energy. For example, when the drying barrel 1 is started, this energy is used to preheat the inside of the barrel. After drying is completed, the induction valve 7 is opened, allowing the dried material to be discharged through the discharge port 2, thus completing the drying of the polymer coating.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
