Description

Technical Field

[0001] This utility model relates to the field of aluminum plate processing technology, and specifically to a pre-conveyor device for coating aluminum plates with oil. Background Technology

[0002] In industrial production, aluminum sheets are widely used in numerous industries, including aerospace, automotive manufacturing, electronics, and building decoration, due to their outstanding advantages such as light weight, ease of processing, and excellent thermal conductivity. In the aluminum sheet processing flow, stacked aluminum sheets are first transferred to an aluminum sheet layering device via forklift. This device separates the stacked aluminum sheets one by one and places them in a standardized manner onto the subsequent transport structure. This transport structure plays two main roles: firstly, it allows operators to randomly inspect the passing aluminum sheets, promptly verifying their appearance quality and dimensional accuracy; secondly, it ensures that the aluminum sheets are transported to the oiling process in a single, stable manner, laying the foundation for the orderly implementation of subsequent coating operations.

[0003] However, aluminum sheets are chemically reactive. Even with the protection provided during the aforementioned transfer, layering, and transport processes, their surface is still susceptible to chemical reactions with oxygen, carbon dioxide, and moisture in the air during storage, transportation, and subsequent processing, leading to oxidation and corrosion. This not only damages the smoothness and cleanliness of the aluminum sheet surface but may also weaken its tensile strength, hardness, and other mechanical properties, adversely affecting the assembly accuracy, service life, and quality stability of the final product. Therefore, implementing scientific and effective protective treatments for aluminum sheet surfaces has become an essential and crucial step in the aluminum sheet processing flow.

[0004] Currently, applying oil coatings to protect aluminum sheet surfaces is one of the mainstream technical approaches in the industry. The oils used for protection possess excellent barrier properties, preventing corrosive media from contacting the aluminum sheet surface; they also have good adhesion, adhering tightly to the aluminum sheet surface and resisting peeling; and they have excellent weather resistance, maintaining their protective effect in different temperature and humidity environments. These characteristics allow them to form a continuous and uniform protective film on the aluminum sheet surface. This film not only blocks external corrosive media from contacting the aluminum substrate but also reduces surface scratches during aluminum sheet handling and stacking, providing reliable protection for subsequent stamping, welding, bending, and other processing steps. Among these methods, the oil roller coating process has become the preferred solution for most aluminum sheet processing companies due to its simple equipment structure, low maintenance costs, high coating efficiency, and adaptability to continuous production lines.

[0005] The core working principle of the oiling roller coating process is as follows: A protective oil is precisely delivered to the surface of the oiling roller using an oil supply system, which typically includes an oil tank, oil pump, filter components, and flow control device. Simultaneously, auxiliary structures such as a scraper and metering roller control the oil volume, ensuring a uniform oil film of a preset thickness is formed on the oiling roller surface. Then, utilizing the rolling contact between the oiling roller and the aluminum plate, combined with the preset pressure of the equipment, the oil film on the oiling roller surface is completely transferred to the aluminum plate surface, thus completing the coating operation. However, in actual production, this process has significant technical defects: after the oiling roller completes coating the previous aluminum plate, it is affected by factors such as uneven contact pressure distribution, differences in the microstructure of the aluminum plate surface, and the inherent flow characteristics of the oil itself. Uneven contact pressure distribution often manifests as greater pressure at both ends of the roller than in the middle. Differences in the microstructure of the aluminum plate surface may include minor scratches or unevenness. Furthermore, the fluidity of the oil itself decreases at low temperatures and it tends to diffuse at high temperatures. These factors together lead to phenomena such as localized oil loss, inconsistent thickness, or localized accumulation of the originally uniform oil film on the oiling roller surface.

[0006] In theory, if the subsequent aluminum sheet to be coated can completely cover the area where the previous aluminum sheet contacted the coating roller, the uneven oil film on the coating roller surface can be corrected to some extent under the new rolling contact and pressure. However, in actual production line operation, deviations in feeding positioning often prevent subsequent aluminum sheets from completely covering the contact area between the previous aluminum sheet and the coating roller. Specifically, although the aluminum sheet layering device has placed the aluminum sheet on the conveyor structure in a standardized posture, the conveyor structure may affect the conveying state of the aluminum sheet during the conveying process due to problems such as fluctuations in the conveyor belt speed, inconsistent local friction coefficients between the aluminum sheet and the conveyor surface, or wear of the conveyor guide components. Among these, inconsistent local friction coefficients between the aluminum sheet and the conveyor surface are mostly caused by oil or impurities adhering to the conveyor surface. These problems will eventually lead to positional shifts or skewed postures of the aluminum sheet, causing it to enter the coating area of ​​the coating roller in a non-standard state, failing to achieve complete coverage of the previous contact area.

[0007] In this situation, uneven oil films will remain on the surface of the oiling roller in areas not covered by subsequent aluminum plates. These uneven oil films will directly transfer to the surface of subsequent aluminum plates, resulting in areas where the oil is applied too thickly, too thinly, or even completely absent. This not only affects the quality of the oil coating on the aluminum plate surface, compromising the uniformity and integrity of the coating, but also significantly weakens the protective effect, posing a major threat to subsequent processing steps, product quality control, and market competitiveness. Utility Model Content

[0008] The purpose of this invention is to solve the problem that deviations easily occur during the conveying of aluminum plates in the prior art, which affect the quality of aluminum plate oiling, and to provide a pre-defined conveying device for aluminum plate oiling.

[0009] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: a pre-conduction device for coating aluminum plates, comprising a support that can be correspondingly arranged with the coating device, the support being provided with a belt transmission structure and a chain transmission structure, and the belt transmission structure and the chain transmission structure being arranged in parallel to transport the aluminum plate body into the coating device. The belt conveyor structure includes multiple conveyor belts rotatably mounted on a support. The multiple conveyor belts can rotate at the same speed as the oiling roller of the oiling device, so that the conveyor belts use static friction to transport the aluminum plate body into the designated position of the oiling roller. The chain transmission structure includes multiple chains mounted on a support. The chains rotate at the same speed as the conveyor belt, and multiple push blocks are provided on the chains. The multiple push blocks can form a straightening face on the side of the aluminum plate body away from the oiling device. The straightening face can push the aluminum plate body and maintain the posture of the aluminum plate body during transportation to ensure that each aluminum plate is in contact with the designated position of the oiling roller.

[0010] As a further optimization of the proposed transmission device for coating aluminum plates according to this utility model: the proposed block is connected to the chain link by bolts, and the surface of the proposed block is provided with a nylon layer.

[0011] As a further optimization of the proposed transmission device for coating aluminum plates according to this utility model: each chain is driven by two sprockets mounted on a support. The two sprockets are arranged along the transmission direction of the aluminum plate body, and both sprockets are connected to a chain shaft by a key. The chain shaft is rotatably mounted on the support.

[0012] As a further optimization of the proposed transmission device for coating aluminum plates according to this utility model: the transmission belt is made of polyurethane, and the surface of the transmission belt is provided with anti-slip texture.

[0013] As a further optimization of the proposed conveyor device for coating aluminum plates according to this utility model: the upper surface of the conveyor belt is at the same level as the lowest generatrix of the coating roller of the coating device.

[0014] As a further optimization of the proposed transmission device for coating aluminum plates according to this utility model: each of the transmission belts is driven by two transmission wheels, the two transmission wheels are arranged along the transmission direction of the aluminum plate body, and the transmission wheels are connected to a drive shaft by a key, the drive shaft is rotatably mounted on the support.

[0015] As a further optimization of the proposed conveyor device for coating aluminum plates according to this utility model: the bottom of the conveyor belt is slidably disposed in a U-shaped guide rail, and the guide rail is fixedly disposed on the bracket.

[0016] As a further optimization of the proposed conveying device for coating aluminum plates according to this utility model: a guide plate is fixedly connected to one side of the bracket corresponding to the coating roller by screws, and the guide plate can cover the gap between the coating roller and the bracket.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This invention synchronizes the conveyor belt speed with the oiling roller rotation speed to ensure that each aluminum plate being conveyed sequentially reaches the designated position in the oiling device. Simultaneously, the chain conveyor structure operates synchronously with the conveyor belt. Utilizing the non-slip characteristic of the chain conveyor structure, along with a guide block positioned on it, a corrective surface is formed behind the aluminum plate in the conveying direction. This effectively propels the aluminum plate and prevents relative slippage with the conveyor belt, maintaining the plate's stable posture. Through these dual safeguards, each aluminum plate is ensured to make precise contact with the oiling roller at the same position, effectively avoiding positional deviations during the oiling process, significantly improving coating accuracy, and guaranteeing the consistency and stability of the oiling quality.

[0019] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0020] like Figure 1 As shown, an aluminum plate coating oiling device has a support frame 1 for use with the coating oiling device 7. The support frame 1 is equipped with a belt conveyor structure 2, a chain conveyor structure 3, and a guide plate 6. The components work together to achieve the goal of accurately transporting the aluminum plate body 5 to the designated position of the coating oiling roller. The belt conveyor structure 2 is responsible for the longitudinal transport of the aluminum plate body 5. The chain conveyor structure 3, in conjunction with multiple push blocks 4 connected to it, ensures that the aluminum plate body 5 is aligned with the edge of the coating oiling device 7 and flush with the coating oiling roller. That is, each aluminum plate body 5 enters the same position of the coating oiling roller of the coating oiling device 7 in a suitable posture. The guide plate 6 and the tensioning member 9 provide guarantees for the accurate transport of the aluminum plate body 5 from two directions: stabilizing the transport direction and controlling the tension of the transmission components, respectively.

[0021] like Figure 2 As shown, the belt transmission structure 2 consists of a drive shaft 201, transmission wheels 202, a transmission belt 203, and a guide rail 8. The two ends of the drive shaft 201 are mounted on the two side plates of the bracket 1 via deep groove ball bearings. The preferred model of the deep groove ball bearing is 6205, which provides good rotational flexibility and load-bearing capacity, allowing the drive shaft 201 to rotate flexibly to transmit power. The transmission wheels 202 are made of rubber, which increases friction with the transmission belt 203 and avoids wear caused by hard contact. The transmission wheels 202 are fixed to the drive shaft 201 via key connections. At least two transmission wheels 202 are symmetrically installed on each drive shaft 201 to ensure that the transmission belt 203 does not deviate during operation. The conveyor belt 203 is a polyurethane synchronous belt, and its surface is textured with anti-slip patterns to enhance friction with the aluminum plate body 5. The conveyor belt 203 is wound around the front and rear sets of conveyor wheels 202 to form a closed transmission channel. The upper surface of the conveyor belt 203 is at the same level as the lowest generatrix of the oiling roller of the oiling device 7, ensuring that the aluminum plate body 5 can make precise contact with the surface of the oiling roller when it is transported to the bottom of the oiling roller. At the same time, the running speed of the conveyor belt 203 is controlled by a variable frequency motor, which is directly connected to the drive shaft 201 through a coupling. This results in high transmission efficiency and stable power transmission. The speed of the conveyor belt 203 is strictly synchronized with the rotation speed of the oiling roller of the oiling device 7, thereby achieving no relative slippage between the aluminum plate body 5 and the surface of the oiling roller during transportation, ensuring that each aluminum plate body 5 can contact the same position of the oiling roller. To further prevent the conveyor belt 203 from deviating during operation, a guide rail 8 is also provided on the support 1 to limit the lateral displacement of the conveyor belt 203. The guide rail 8 has a U-shaped cross section to effectively limit the lateral displacement of the conveyor belt 203 and ensure the stability of the transmission direction.

[0022] The chain transmission structure 3 consists of a sprocket 302, a chain shaft 303, and a chain 301. It works in conjunction with the pre-set block 4 to further stabilize the posture of the aluminum plate body 5. The number of teeth on the sprocket 302 is designed according to the actual transmission ratio requirements, balancing transmission stability and efficiency. The sprocket 302 is fixed to the chain shaft 303 via a key connection. The chain shaft 303 is parallel to the drive shaft 201. Both ends of the chain shaft 303 are mounted on the upright plate of the bracket 1 via deep groove ball bearings. The chain shaft 303 is connected to the drive shaft 201 via gear transmission, with a transmission ratio set to 1:1. This ensures that the running speed of the chain transmission structure 3 is completely synchronized with that of the belt transmission structure 2, preventing relative displacement between the chain and the aluminum plate body 5 and thus affecting positioning accuracy.

[0023] The gear transmission specifically includes a driving gear, a driven gear, and a gear cover. The driving gear is fixed to the end of the transmission shaft 201 near the variable frequency motor via a key connection. The driven gear is fixed to the end of the chain shaft 303 corresponding to the driving gear via a key connection. The module and number of teeth of the driving and driven gears are exactly the same, thus achieving a 1:1 constant speed transmission and ensuring that the speeds of the chain shaft 303 and the transmission shaft 201 are exactly the same, thereby ensuring that the running speeds of the chain transmission structure 3 and the belt transmission structure 2 are synchronized. To avoid impurities being drawn into the gear transmission process or safety hazards caused by accidental contact by personnel, a gear cover is provided on the outside of the driving and driven gears. The gear cover is fixed to the upright plate of the bracket 1 by bolts. An observation window is provided on the gear cover, which is sealed with a transparent acrylic sheet, allowing personnel to observe the meshing status and wear of the gears at any time without affecting the normal transmission of the gears.

[0024] The chain 301 is a roller chain, which is wound around the front and rear sets of sprockets 302 to form a transmission channel parallel to the belt transmission structure 2. The upper surface of the chain 301 is 2-3 mm lower than the upper surface of the belt transmission structure 2 to prevent the chain 301 from contacting the lower surface of the aluminum plate body 5 and affecting transportation. The outer surface of the estimating block 4 is covered with a nylon layer. The nylon layer is soft and has a certain strength, which can prevent scratching the surface of the aluminum plate body 5. The estimating block 4 is fixed to the chain links of the chain 301 by bolts. The installation spacing is designed according to the width of the aluminum plate body 5 to ensure that each aluminum plate body 5 has a corresponding number of estimating blocks 4 on one side along the transport direction during transportation. When the aluminum plate body 5 is placed on the conveyor belt 2, the chain 301 drives the estimating blocks 4 to run synchronously. That is, multiple chains 301 drive multiple corresponding estimating blocks 4 to run synchronously, so that multiple estimating blocks 4 arranged flush with the edge of the aluminum plate body 5 away from the oiling device 7 form a straightening face. The straightening face can move synchronously with the aluminum plate body 5 on the side away from the oiling device 7, thereby effectively avoiding the posture deviation of the aluminum plate body 5 due to the relative slippage between the conveyor belt 2 and the aluminum plate body 5, and further ensuring that each aluminum plate body 5 can contact the same position with the oiling roller.

[0025] The guide plate 6 is made of stainless steel, balancing structural strength and lightweight requirements. It is symmetrically installed at the discharge end of the bracket 1, i.e., on the side of the bracket 1 closest to the oiling device 7. The guide plate 6 assists in guiding the position of the aluminum plate body 5, preventing it from being suspended in the space between the bracket 1 and the oiling roller, which would prevent the aluminum plate body 5 from being unable to enter the oiling roller stably. This guides the aluminum plate body 5 to enter the oiling device 7 stably and accurately, further reducing positional deviations in the subsequent oiling process and ensuring coating accuracy.

[0026] The operation and control methods of the variable frequency motor in this embodiment should be understood as existing technology.

[0027] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
