Description

Technical Field

[0001] This utility model belongs to the technical field of paper card production equipment, and in particular relates to a high-efficiency oiling device for paper card production. Background Technology

[0002] In the paper card production process, the oiling process is a key step in improving the surface performance of paper cards. Its main function is to enhance the wear resistance, water resistance and gloss of the paper card surface, thereby extending the service life of the paper card and improving its appearance quality. A Chinese patent application with publication number CN222781869U discloses an efficient oiling device for paper card production, including a bottom oiling structure and a top oiling structure at the top of the bottom oiling structure. The bottom oiling structure and the top oiling structure have the same composition. Both the bottom oiling structure and the top oiling structure include an oil storage tank, a first fixed frame, an oiling roller, a motor, a second cantilever rod, a second limiting roller, a second fixed frame, a rotating shaft, a driven shaft, and an oil drain valve. A support frame is fixedly installed between the two outer surfaces of the oil storage tank in the bottom oiling structure and the two outer surfaces of the oil storage tank in the top oiling structure. The efficient oiling device for paper card production described in this utility model has a bottom oiling structure, which facilitates oiling the lower outer surface of the card paper, and a top oiling structure, which facilitates oiling the upper outer surface of the card paper, thereby improving the oiling efficiency. Although this patent has a high oiling efficiency, it still has the drawback of not having an accelerated drying structure. After the paper card is oiled, the oil on its surface needs to be dried naturally, which results in a long drying time. During this period when the oil is not completely dried, the oil on the surface of the paper card is in an uncured state and is very easy to attract impurities and dust from the air. Once these impurities and dust adhere to the surface of the paper card, they will not only seriously affect the appearance quality of the paper card, causing stains, spots and other defects on the surface of the paper card, reducing the product qualification rate, but also have an adverse effect on the subsequent performance of the paper card. To address these issues, we provide a high-efficiency oiling device for paper card production. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency oiling device for paper card production. By combining the side drying component and the top drying component, it solves the problem that the existing paper card production oiling device does not have an accelerated drying structure, and the oil on the surface of the paper card needs to be dried naturally after oiling, which reduces the quality of paper processing.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0005] This utility model relates to a high-efficiency oiling device for paper card production, comprising a lower oil tank, a support frame fixedly connected to one side of the lower oil tank, an upper oil tank fixedly connected to the top of the support frame, a side drying assembly disposed on one side of the support frame, a connecting frame fixedly connected to the top of the side drying assembly, a top drying assembly disposed on one side of the connecting frame, mounting plates fixedly connected to the tops of both the lower and upper oil tanks, a movable rod disposed between the mounting plates, a motor disposed at one end of the movable rod, an oiling roller fixedly connected to the surface of the movable rod, the side drying assembly comprising a drying shell, one side of the drying shell fixedly connected to the surface of the support frame, an infrared emitter disposed on one side of the inner cavity of the drying shell, and guide rollers disposed at the top and bottom of the inner cavity of the drying shell.

When the fan is turned on, it draws outside air into the inner cavity of the coil. After being heated in the inner cavity of the coil, the air is blown into the inner cavity of the drying chamber through the hot air hood to dry the surface of the paper.

[0007] The present invention is further configured such that a load-bearing frame is fixedly connected to the bottom of the drying shell, a guide rail is fixedly connected to the top of the inner cavity of the load-bearing frame, a collection box is provided in the inner cavity of the guide rail, the load-bearing frame is located at the bottom of the drying shell, which can support the drying shell and improve the stability of the drying shell, and the push-pull collection box provided in the inner cavity of the load-bearing frame can collect the oil dripping from the paper.

[0008] The present invention is further configured such that an oil drain pipe is provided at the bottom of one side of the lower oil tank and the upper oil tank, and an oil injection pipe is provided at the top of one side of the lower oil tank and the upper oil tank. Oil can be added to the inner cavity of the lower oil tank and the upper oil tank through the oil injection pipe, and the remaining oil in the inner cavity of the lower oil tank and the upper oil tank can be discharged through the oil drain pipe.

[0009] The present invention is further configured such that a base is fixedly connected to the bottom of the lower oil tank, and support pads are fixedly connected to both sides of the bottom of the base. The support pads have high friction, which can improve the anti-slip properties of the bottom of the base. The base with good anti-slip properties can more stably support the oiling device.

[0010] The present invention is further configured such that a side frame is fixedly connected to the bottom of the drying box, the bottom of the side frame is fixedly connected to the top of the base, and the top and bottom of the side frame are respectively fixedly connected to the bottom of the drying box and the top of the base.

[0013] The present invention has the following beneficial effects.

[0014] 1. In this invention, after the paper is coated on both sides, the specific wavelength radiation energy generated by the infrared emitter can be directly absorbed by the oil and the paper surface and converted into heat energy, which quickly reduces the viscosity of the oil and increases its fluidity. At the same time, it causes the low-boiling-point solvent or water on the surface of the oil to evaporate instantly, laying the foundation for subsequent deep drying. Then, the electric heating plate is powered on to heat the inner cavity and coil of the heating box. After the fan draws the outside air into the coil and heats it, it blows a high-speed hot airflow onto the surface of the paper in the drying box through the hot air hood. This continuously removes the saturated volatile gases on the surface of the oil film, breaks the gas-liquid balance, and forces the liquid molecules inside the oil to continuously escape and evaporate, significantly accelerating the overall drying speed.

[0015] 2. This utility model accelerates the initial curing of the oil through infrared pretreatment and promotes rapid and complete curing of the oil through hot air drying. Throughout the process, the oil is always in a relatively closed and controlled drying environment, which reduces the chance of contact with external impurities. This effectively prevents stains, spots and other defects from appearing on the surface of the paper card due to the adhesion of impurities, and ensures the appearance integrity of the paper card.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-6 This utility model is a high-efficiency oiling device for paper card production, including a lower oil tank 1, a support frame 2 fixedly connected to one side of the lower oil tank 1, an upper oil tank 3 fixedly connected to the top of the support frame 2, a side drying component 4 provided on one side of the support frame 2, a connecting frame 5 fixedly connected to the top of the side drying component 4, a top drying component 6 provided on one side of the connecting frame 5, mounting plates 7 fixedly connected to the tops of both the lower oil tank 1 and the upper oil tank 3, a movable rod 8 provided between the mounting plates 7, a motor 9 provided at one end of the movable rod 8, an oiling roller 10 fixedly connected to the surface of the movable rod 8, the side drying component 4 including a drying shell 401, one side of the drying shell 401 fixedly connected to the surface of the support frame 2, an infrared emitter 402 provided on one side of the inner cavity of the drying shell 401, and guide rollers 403 provided at the top and bottom of the inner cavity of the drying shell 401.

[0026] Specifically: Motor 9 is turned on, and the output of Motor 9 drives the movable rod 8 to rotate. The movable rod 8 drives the oiling roller 10 to rotate, thereby applying oil to both sides of the paper. At the same time, infrared emitter 402 is turned on. The specific wavelength radiation energy generated by infrared emitter 402 penetrates the air almost without loss and is directly absorbed by the oil and the surface of the paper, converting into heat energy. This rapidly reduces the viscosity of the oil on the paper surface, increases its fluidity, and prepares for subsequent penetration and evaporation. Some of the low-boiling-point solvents or water on the surface of the oil will evaporate instantly. Heating plate 604 is turned on, and the heat generated by heating plate 604 heats the inner cavity of heating box 603 and coil 605. Fan 606 is turned on. The fan 606 draws outside air into the inner cavity of the coil 605. After being heated in the inner cavity of the coil 605, the gas is blown into the inner cavity of the drying chamber 601 through the hot air hood 602, and then blown onto the surface of the paper. The high-speed hot airflow continuously "blows away" the saturated volatile gases (solvent vapor or water vapor) that are closely attached to the surface of the oil film, so that the vapor pressure on the surface of the oil film is always lower than its saturated vapor pressure. This breaks the gas-liquid balance, forcing the internal liquid molecules to continuously escape to the surface and evaporate, thereby greatly accelerating the drying speed. The motor 9 is a three-phase asynchronous motor, model YE2-80M2-4, and the fan 606 is a centrifugal fan, model CF-4-72No.3.6A.

[0027] The top drying assembly 6 includes a drying chamber 601, one side of which is fixedly connected to a connecting frame 5. A hot air hood 602 is installed at the bottom of the inner cavity of the drying chamber 601. A heating chamber 603 is fixedly connected to the bottom of the drying chamber 601. An electric heating plate 604 is fixedly connected to the rear side of the inner cavity of the heating chamber 603. A coil 605 is installed in the inner cavity of the heating chamber 603. A fan 606 is fixedly connected to the bottom of the heating chamber 603. A load-bearing frame 11 is fixedly connected to the bottom of the drying shell 401. A guide rail 12 is fixedly connected to the top of the inner cavity of the load-bearing frame 11. A drawer is installed in the inner cavity of the guide rail 12. Oil drain pipes are provided at the bottom of one side of the header 13, the lower oil tank 1 and the upper oil tank 3, and oil injection pipes are provided at the top of one side of the lower oil tank 1 and the upper oil tank 3. The bottom of the lower oil tank 1 is fixedly connected to the base 14, and the two sides of the bottom of the base 14 are fixedly connected to the support pads. The bottom of the drying box 601 is fixedly connected to the side frame, and the bottom of the side frame is fixedly connected to the top of the base 14. The front of the drying shell 401 is provided with a protective door, and the front of the protective door is fixedly connected to a handle. The front of the drying box 601 is provided with a sealing door, and a sealing strip is fixedly connected to the edge of the sealing door surface.

[0028] Specifically: The heating plate 604 is turned on, generating heat to heat the inner cavity of the heating chamber 603 and the coil 605. The fan 606 is turned on, drawing outside air into the inner cavity of the coil 605. After being heated in the inner cavity of the coil 605, the air is blown into the inner cavity of the drying chamber 601 through the hot air hood 602 to dry the surface of the paper. The support frame 11 is located at the bottom of the drying shell 401, providing support and improving its stability. The push-pull collection box 13 inside the support frame 11 collects dripping oil from the paper. Oil can be added to the inner cavities of the lower oil tank 1 and the upper oil tank 3 via the oil injection pipe, and drained from the lower oil tank 1 and the upper oil tank 3 via the oil discharge pipe. The remaining oil in the inner cavity of box 3 is discharged. The high friction at the bottom of the support pad improves the anti-slip properties of the bottom of base 14. The anti-slip base 14 can more stably support the oiling device. The top and bottom of the side frame are fixedly connected to the bottom of the drying box 601 and the top of the base 14, respectively. The support of the side frame can improve the stability of the drying box 601. Closing the protective door can protect the inner cavity of the drying shell 401, reduce the heat loss of the inner cavity of the drying shell 401, and the protective door is easy to open. After opening, the paper can be manipulated to pass through the surface of the guide roller 403. The sealing strip can improve the sealing performance of the sealing door for the drying box 601. The sealing door with good sealing performance can slow down the rate of heat loss from the inner cavity of the drying box 601.

[0029] The working principle of this utility model is as follows: Sufficient oil is added to the inner cavities of the upper oil tank 3 and the lower oil tank 1. Then, paper is passed sequentially through the top of the upper oil roller 10 in the inner cavity of the lower oil tank 1, one side of the guide roller 403, and the top of the guide roller 403 in the inner cavity of the upper oil tank 3. The motor 9 is turned on, and the output end of the motor 9 drives the movable rod 8 to rotate. The movable rod 8 drives the upper oil roller 10 to rotate, thereby applying oil to both sides of the paper. At the same time, the infrared emitter 402 is turned on. The specific wavelength radiation energy generated by the infrared emitter 402 penetrates the air with almost no loss and is directly absorbed by the oil and the surface of the paper, converted into heat energy, and rapidly reduces the viscosity of the oil on the paper surface, increasing its fluidity and preparing for subsequent penetration and evaporation. Some low-boiling-point solvents or water will evaporate instantly. The heating plate 604 is turned on, and the heat generated by the heating plate 604 heats the inner cavity of the heating box 603 and the coil 605. The fan 606 is turned on, and the fan 606 draws outside air into the inner cavity of the coil 605. After the gas is heated in the inner cavity of the coil 605, it is blown into the inner cavity of the drying box 601 through the hot air hood 602, and then blown onto the surface of the paper. The high-speed hot airflow continuously "blows away" the saturated volatile gases (solvent vapor or water vapor) that are close to the surface of the oil film, so that the vapor pressure on the surface of the oil film is always lower than its saturated vapor pressure. This breaks the gas-liquid balance, forcing the internal liquid molecules to continuously escape to the surface and evaporate, thereby greatly accelerating the drying speed.
