Description

TECHNICAL FIELD

[0001] The present application relates to the field of heating devices, in particular to a heating control device of an aluminum foil laminating machine. BACKGROUND

[0002] The aluminum foil laminating machine, as an important production equipment, is widely used in the fields of food packaging, medicine packaging, cosmetic packaging, etc., and is mainly used for laminating aluminum foil with plastic film, paper, fabric and other substrates. This equipment applies pressure and heat to the aluminum foil and the substrate through the laminating roller. Specifically, the laminating roller applies pressure to the passing aluminum foil and substrate through rotational motion, while the built-in heating device provides the necessary temperature conditions.

[0003] The laminating roller is usually driven to rotate by the forward power of the aluminum foil itself, but sometimes the power provided is not enough to make the laminating roller rotate smoothly due to the thinness of the aluminum foil, resulting in uneven bonding of the aluminum foil and the substrate, affecting the quality of the final product.

[0004] Therefore, how to ensure the stable rotation of the laminating roller and achieve efficient and uniform heating has become a technical problem to be solved. CONTENT OF THE INVENTION

[0005] The present application provides a heating control device of an aluminum foil laminating machine, which adopts the following technical solution:

[0006] A heating control device of an aluminum foil laminating machine, comprising a laminating roller, a driving mechanism and a heater arranged inside the laminating roller; the aluminum foil laminating machine has a rack, and the laminating roller is rotationally connected with the rack;

[0007] The driving mechanism comprises a motor and a transmission assembly, and the motor is connected with the laminating roller through the transmission assembly; the heater comprises a heater, and the end of the laminating roller is provided with a current collector ring, and the heater is in conductive connection with the current collector ring; an electric brush in contact with the current collector ring is arranged on the rack, and the electric brush is connected with a power source through a wire.

[0008] By adopting the above technical solution, the motor of the driving mechanism is connected with the laminating roller through the transmission assembly, which ensures the active rotation of the laminating roller and avoids the problem of insufficient power caused by the thinness of the aluminum foil. The heater comprises a heater, and the reliable connection with the power source is realized through the current collector ring and the electric brush, which ensures the continuity and stability of the heating process, thereby improving the laminating effect of the aluminum foil and the substrate.

[0009] Preferably, a fixed sleeve is arranged on the rack, the central shaft of the laminating roller is arranged in the fixed sleeve and is rotationally connected with the fixed sleeve in the same axis, and the electric brush is arranged on the fixed sleeve.

[0010] By adopting the above technical solution, a stable rotational connection between the composite roller and the frame can be achieved, ensuring smooth operation of the composite roller during work and avoiding problems such as poor bonding between the aluminum foil and the substrate caused by vibration or shaking. Simultaneously, placing the brushes on the fixed sleeve makes the contact between the brushes and the slip ring more reliable, ensuring the stability of current transmission, thereby improving the heater's working efficiency and safety.

[0011] Preferably, the composite roller includes an outer roller and an inner roller, with a gap between the outer roller and the inner roller, and the inner roller and the outer roller are fixedly connected by a connector, with a heating medium filling the gap; the heater is located on the inner roller.

[0012] By adopting the above technical solution, the gap between the inner and outer rollers of the composite roller is filled with a heating medium, which can effectively improve the heat transfer efficiency, ensure uniform surface temperature of the composite roller, and thus improve the bonding quality between the aluminum foil and the substrate. At the same time, the heater is located on the inner roller, which can provide heat more concentratedly and further ensure the heating effect.

[0013] Preferably, the heating medium is heat transfer oil.

[0014] By adopting the above technical solution, the heating medium is set as heat-conducting oil, which can effectively improve the heat transfer efficiency and ensure that the composite roller is heated evenly inside and out, thereby improving the composite quality of aluminum foil and substrate.

[0015] Preferably, the inner roller is provided with a protrusion, and a groove is formed on the inner wall of the inner roller at a position corresponding to the protrusion, and the heater is disposed in the groove.

[0016] By adopting the above technical solution, the protrusions and corresponding grooves on the inner roller can effectively position and fix the heater, ensuring the stability and reliability of the heater in the inner roller, while increasing the heating area, avoiding uneven heating, and improving composite quality and production efficiency.

[0017] Preferably, both the protrusion and the heater are arranged along the length of the inner roller.

[0018] By adopting the above technical solution, the heater and protrusions are evenly distributed along the length of the inner roller, thereby ensuring more uniform heating and improving the quality and efficiency of the composite process. At the same time, this design helps reduce heat loss and improve energy utilization efficiency.

[0019] Preferably, the protrusion is connected to the outer roller as a connector.

[0020] By adopting the above technical solution, the protrusion is used as a connector to connect with the outer roller, which can ensure a stable connection between the inner and outer rollers, thereby improving the overall structural strength and stability of the composite roller, avoiding loosening or deformation during high-temperature and high-speed operation, and ensuring the bonding quality between the aluminum foil and the substrate.

[0021] Preferably, the heater sidewall is fitted into the interior of the groove.

[0022] By adopting the above technical solution, the heat transfer efficiency between the heater and the inner roller is improved, thereby enhancing heating uniformity and heating speed. Simultaneously, the tight fit between the heater and the inside of the groove increases structural stability and reduces the risk of displacement due to vibration or impact.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a drive mechanism including a motor and transmission components, the composite roller can rotate actively, avoiding the problem of uneven bonding caused by insufficient power of the aluminum foil itself, and improving the bonding quality and stability of the aluminum foil and the substrate;

[0025] 2. The heater installed inside the composite roller works in conjunction with the slip ring and brush to achieve a reliable connection between the heater and the power supply, ensuring the continuity and stability of the heating process and solving the problem of uneven heat distribution in traditional heating methods;

[0026] 3. The gap between the inner and outer rollers is filled with heat-conducting oil, which allows the heating medium to transfer heat evenly, improving the heating efficiency and temperature uniformity of the composite roller, thereby enhancing the composite effect and production efficiency.

[0031] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0032] The heating control device for the aluminum foil laminating machine provided in this application embodiment refers to... Figure 1 and Figure 2 The aluminum foil laminating machine includes a composite roller 1, a drive mechanism 2, and a heater 3 located inside the composite roller 1. The machine has a frame 4, with the composite roller 1 rotatably connected to the frame 4. The drive mechanism 2 includes a motor 21 and a transmission assembly 22; the motor 21 is connected to the composite roller 1 via the transmission assembly 22. The heater 3 includes a heater 3, with a collector ring at the end of the composite roller 1, and the heater 3 is electrically connected to the collector ring. A brush is mounted on the frame 4, contacting the collector ring, and the brush is connected to a power source via a wire. This design effectively solves the problems of unstable rotation and uneven heating of the composite roller 1 during the aluminum foil lamination process, improving lamination quality and production efficiency.

[0033] Reference Figure 3 Specifically, the composite roller 1 includes an outer roller 11 and an inner roller 12, with a gap between the outer roller 11 and the inner roller 12. The inner roller 12 and the outer roller 11 are fixedly connected by a connector, and the gap is filled with a heating medium 13. A heater 3 is located on the inner roller 12. This design ensures that the heating medium 13 is evenly distributed between the inner and outer rollers 11, thereby achieving a more uniform heating effect. For example, the heating medium 13 can be heat-conducting oil, whose excellent thermal conductivity can quickly transfer heat and improve heating efficiency.

[0034] The outer roller 11 and inner roller 12 can be made of high-temperature resistant metals, such as stainless steel or aluminum alloy, to ensure that they will not deform or be damaged in high-temperature environments. The surface of the outer roller 11 can be specially treated, such as chrome plating or Teflon coating, to increase its wear resistance and anti-adhesion properties and extend its service life.

[0035] Reference Figure 2 A fixed sleeve 5 is installed on the frame 4. The central shaft of the composite roller 1 passes through the fixed sleeve 5 and is coaxially and rotatably connected to the fixed sleeve 5. The brush is located on the fixed sleeve 5. This design ensures the stable rotation of the composite roller 1 and reduces vibration and noise. The fixed sleeve 5 can be made of high-strength steel to withstand a large load.

[0036] The inner roller 12 has a protrusion 121, and a groove is formed on the inner wall of the inner roller 12 at a position corresponding to the protrusion 121. The heater 3 is disposed in the groove. Both the protrusion 121 and the heater 3 are arranged along the length of the inner roller 12, which ensures that the heater 3 is evenly distributed on the entire composite roller 1 and improves the heating effect. The protrusion 121 can also serve as a connector to the outer roller 11, enhancing the connection strength between the inner and outer rollers 11.

[0037] The sidewall of heater 3 fits snugly against the interior of the groove, minimizing heat loss and maximizing thermal efficiency. The outer shell of heater 3 can be made of high-temperature resistant ceramic material to prevent deformation or damage at high temperatures.

[0038] The implementation principle of this embodiment is as follows: Driven by the motor 21 and the transmission assembly 22, the composite roller 1 can rotate stably, avoiding the problem of unstable rotation caused by insufficient power of the aluminum foil itself. Simultaneously, the heater 3 inside the inner roller 12 is connected to the power supply through a slip ring and brushes, achieving efficient heating. The presence of the heating medium allows heat to be evenly distributed between the inner and outer rollers 11, improving the heating effect. The entire device has a compact structure and is easy to operate, significantly improving the quality and production efficiency of aluminum foil lamination.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
