Description

TECHNICAL FIELD

[0001] The present application relates to the field of stamping processing, in particular to a metal plate feeding device with self-cleaning plate surface. BACKGROUND

[0002] In the existing metal plate stamping processing technology, due to the complexity of the production process and multi-process operation, the surface of the metal plate will inevitably be contaminated with oil during transportation and processing. These oil stains mainly come from the residual lubricant in the previous process or environmental pollution during storage and transportation. Before the start of stamping processing, in order to meet the technical requirements of subsequent processing and the strict requirements of customers on the cleanliness of the finished product surface, the metal plate usually needs to be cleaned. This cleaning process often uses cleaning tanks or independent cleaning equipment to remove surface oil stains through solvent cleaning or physical wiping. However, this method inevitably increases the complexity of the production line and poses a considerable challenge to production efficiency and cost control.

[0003] Firstly, using a cleaning tank to clean metal plates requires additional production space and increases equipment investment. This not only increases the initial equipment purchase cost, but also requires additional investment in cleaning agents, energy and maintenance costs in the long-term production. Secondly, the introduction of a cleaning tank increases an independent process, making the production process more complex and resulting in a decline in overall production efficiency. In addition, the use of a cleaning tank may have environmental problems, especially if the cleaning agent waste is not properly treated, which can potentially pollute the environment and require additional waste treatment equipment and costs. Finally, since cleaning is an independent process, the surface cleaning of the metal plate is not closely linked to the subsequent processing process, which can weaken the cleaning effect during handling and stacking, affecting the surface quality of the final product.

[0004] Based on the above problems, the traditional metal plate cleaning method has obvious shortcomings. The contradiction between production efficiency and cost has gradually become an important bottleneck restricting the development of the industry, and the complex process flow also poses a challenge to the automation and efficiency of the overall production line. In addition, the continuous improvement of customer requirements for product quality makes it difficult for existing cleaning methods to achieve an ideal balance between cost and effect. Therefore, how to achieve efficient, low-cost and environmentally friendly surface cleaning during the stamping processing of metal plates has become an important direction for technical optimization in this field. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to at least overcome one of the deficiencies in the prior art, provide a metal plate feeding device with a self-cleaning plate surface, which integrates cleaning function in the feeding device, so that the metal plate can complete the removal of surface oil stains at the same time as feeding, thereby eliminating the need for independent cleaning process. This technology not only effectively simplifies the production process and improves the overall production efficiency, but also significantly reduces the production cost.

[0006] To achieve the above purpose, the present application discloses a metal plate feeding device with a self-cleaning plate surface, which comprises a base, a bearing frame mounted on the base, an upper glue roller and a lower glue roller group arranged vertically in the height direction, a cleaning liquid tank located on the base and opposite to the lower glue roller group, and a hot air drying assembly mounted on the base, wherein the lower glue roller group comprises a lower glue roller opposite to the upper glue roller and a cleaning glue roller horizontally opposite to the lower glue roller, which are driven by a driving mechanism to realize synchronous reverse motion; the cleaning glue roller comprises a composite roller, including a roller core and a brush layer arranged outside the roller core, which is opposite to the cleaning liquid tank, and at least the brush layer is immersed below the cleaning liquid surface of the cleaning liquid tank during operation, and the oil removal and cleaning are completed by the brush layer on the surface of the metal plate; the hot air drying assembly comprises an upper air tank and a lower air tank opposite to the upper air tank, a plurality of air outlets are formed on the opposite surfaces of the upper air tank and the lower air tank, and a fan and an air duct with a heating assembly connected to the fan are installed in the upper air tank and the lower air tank, hot air is output through the air duct and discharged from the air outlets, so as to form a drying channel between the upper air tank and the lower air tank.

[0007] In some embodiments, the cleaning liquid tank is supplied with liquid by an external liquid supply device, and a liquid level sensor is arranged in the cleaning liquid tank, which is connected to an external controller for controlling the liquid level in the cleaning liquid tank.

[0008] In some embodiments, the height of the upper glue roller is adjustable.

[0009] Compared with the prior art, the present application has at least one of the following beneficial effects:

[0010] 1. Simplify production process and improve efficiency: The device integrates cleaning function, combines surface cleaning of metal plate with feeding process, eliminates the need for independent cleaning process, reduces the complexity of production links, improves the overall operation efficiency of production line, and avoids time waste caused by setting and subsequent processing of cleaning process.

[0011] 2. Reduce production cost: Since additional cleaning equipment and cleaning agent investment are no longer needed, the device can effectively reduce the equipment purchase and operation cost in the production process.

[0024] See attached document Figures 1-4 This embodiment discloses a metal plate feeding device with a self-cleaning surface, aiming to solve the problems of complex equipment, low production efficiency, and high cost in traditional metal plate surface cleaning processes. This device simplifies the metal plate processing procedure, improves production efficiency, and significantly reduces production costs by integrating cleaning and drying functions. Overall, the device has a compact design, and the rational configuration and precise cooperation of its components enable efficient removal of oil stains from the metal plate surface while simultaneously drying it, ensuring that the metal plate achieves the required surface cleanliness before entering subsequent processes.

[0025] The basic structure of the feeding device includes a base 1, a bearing frame 2 mounted on the base 1, an upper rubber roller 3 and a lower rubber roller assembly 4, a cleaning liquid tank 5, and a hot air drying assembly 6. The coordinated operation of these parts ensures the smooth cleaning and drying of the metal sheet during transport. The base 1 serves as the frame of the entire device, providing necessary support and stability. It is constructed of high-strength steel to ensure stable operation under high load conditions. The bearing frame 2, mounted on the base 1, supports the rotating components of each roller, ensuring the smooth operation of the upper and lower rubber rollers 3 and 4, as well as the cleaning roller 8. The upper rubber roller 3 and the lower rubber roller assembly 4 are located at the upper and lower parts of the base 1, respectively, arranged vertically to form the metal sheet feeding channel. The upper rubber roller 3 pushes the metal sheet through the feeding device, while the lower rubber roller assembly 4 works in conjunction with the cleaning roller 8 to complete the conveying and cleaning tasks of the metal sheet. The cleaning liquid tank 5 is mounted on the base 1 and located below the lower rubber roller assembly 4, opposite the lower rubber roller 7. The tank stores cleaning liquid for cleaning the metal sheet.

[0026] The cleaning rubber roller 8 is a key component in the device, and its design determines the cleaning effect. The cleaning rubber roller 8 is composed of a roller core 10 and a brush layer 11. The roller core 10 is the inner part that supports the brush layer 11, usually made of high-strength steel or other high-rigidity composite materials to ensure that the roller core 10 can withstand long-term wear and tear. The brush layer 11 is made of soft and wear-resistant polyester fiber or nylon material, and its bristles are designed with a certain degree of curvature and elasticity, which enables it to make close contact with the metal plate surface and generate enough friction to remove oil stains, lubricant residues and other contaminants on the surface. The size, density and softness of the brush layer 11 are precisely designed to ensure efficient cleaning of the surface without damaging the metal plate surface.

[0027] The cleaning liquid stored in the cleaning liquid tank 5 has the ability to dissolve oil stains. The liquid level sensor is connected to the external control system, which automatically adjusts the supply of cleaning liquid when the liquid level is too low, ensuring that the cleaning liquid in the tank is always at the appropriate level. The liquid level sensor monitors the liquid level of the cleaning liquid tank 5 in real time, avoiding insufficient or excessive cleaning liquid, and ensuring the stability and consistency of the cleaning effect.

[0028] The working principle of the cleaning rubber roller 8 is that the driving mechanism 9 drives the lower rubber roller 7 and the cleaning rubber roller 8 to move synchronously and reversely, so that the cleaning rubber roller 8 makes frictional contact with the metal plate surface and the brush layer 11 is immersed in the cleaning liquid surface in the cleaning liquid tank 5. During the rotation of the cleaning rubber roller 8, the brush layer 11 rolls on the surface of the metal plate, removing oil stains and contaminants from the surface of the metal plate through friction and cleaning liquid. This process not only removes oil stains on the surface, but also effectively removes dust, particles and other impurities on the surface.

[0029] When the metal plate passes through the cleaning rubber roller 8, it enters the hot air drying assembly 6 for drying treatment. The hot air drying assembly 6 is composed of an upper air tank 12 and a lower air tank 13, and a fan and a heating assembly are installed in each air tank. The fan is responsible for sucking air and sending it to the heating assembly through the air duct. After the heating assembly heats the air, the air flows into the upper air tank 12 and the lower air tank 13 through the air duct and is discharged through the air outlet. The discharged hot air directly blows onto the surface of the metal plate, quickly evaporating the residual moisture during the cleaning process. The relative arrangement between the upper air tank 12 and the lower air tank 13 and the design of the air outlet enable the hot air to evenly cover both sides of the metal plate, ensuring its rapid drying. The entire drying process can be completed in a few seconds, significantly improving production efficiency.

[0030] It is worth noting that the main consideration in the design of the present feeding device is the need for single-sided cleaning of the metal sheet. In actual production, if both sides of the metal sheet need to be cleaned simultaneously, multiple feeding devices can be used in series. This configuration method is very flexible, and the number and arrangement of devices can be adjusted according to actual production needs to meet different production requirements.

[0031] Specifically, the metal sheet is first cleaned on the front side by the first feeding device, and then cleaned on the back side by the second feeding device. In this way, both sides of the metal sheet can be fully cleaned, while reducing the complexity and difficulty of the cleaning process. Each feeding device works independently, ensuring efficient and precise cleaning and drying of the metal sheet surface, avoiding problems such as unstable cleaning effect and residual contaminants in traditional cleaning processes.

[0032] Overall, the metal sheet feeding device provided in this embodiment has a reasonable structure and comprehensive functions, which can effectively improve production efficiency and reduce production costs. The combination of the cleaning rubber roller 8 and the hot air drying assembly 6 ensures that the metal sheet surface is thoroughly cleaned and quickly dried during feeding, ensuring smooth progress of subsequent processing procedures. In addition, by connecting multiple devices in series, the scope of application of the device is wider, and it can meet different production environments and process requirements.

[0033] Although exemplary embodiments of the present disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included within the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and equivalents of these claims are also included.
