Description

Technical Field

[0001] This utility model relates to the field of industrial equipment technology, specifically to a segmented temperature-controlled energy-saving aluminum strip baking tunnel oven. Background Technology

[0002] In the aluminum strip surface treatment process, the paint baking tunnel oven is the core equipment for achieving paint curing. It continuously transports the aluminum strip through the heating zone via a conveyor belt, and completes the baking and curing process by utilizing heat conduction, convection and radiation mechanisms.

[0003] The existing segmented temperature-controlled energy-saving aluminum strip painting tunnel oven has an inconveniently adjustable furnace length. When production needs change, such as adjusting aluminum strip specifications or increasing / decreasing production capacity, the entire set of equipment needs to be replaced. This not only increases equipment investment costs but also reduces the space utilization rate of the production site, making it difficult to adapt to flexible production needs. The heating pipes of the existing furnace are mostly fixedly installed inside the furnace body, and the distance between them and the conveyor belt and the aluminum strip paint surface cannot be adjusted. Different thicknesses and types of paint have different heating distance and temperature requirements. Fixed spacing can easily lead to local overheating or underheating, which affects the paint curing quality and causes energy waste. Therefore, it does not meet the existing needs. To address this, we propose a segmented temperature-controlled energy-saving aluminum strip painting tunnel oven. Utility Model Content

[0004] The purpose of this utility model is to provide a segmented temperature-controlled energy-saving aluminum strip painting tunnel oven to solve the problems mentioned in the background art, such as the inconvenience of adjusting the length of the existing segmented temperature-controlled energy-saving aluminum strip painting tunnel oven. When production needs change, such as adjusting the aluminum strip specifications or increasing or decreasing production capacity, the entire set of equipment needs to be replaced, which not only increases the equipment investment cost but also reduces the space utilization rate of the production site and makes it difficult to adapt to the needs of flexible production. The heating tubes of the existing oven are mostly fixedly installed inside the oven body, and the distance between them and the conveyor belt and the aluminum strip paint surface cannot be adjusted. Different thicknesses and types of paint have different requirements for heating distance and temperature. Fixed spacing can easily lead to local overheating or insufficient heating, which affects the curing quality of the paint surface and causes energy waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a segmented temperature-controlled energy-saving aluminum strip baking tunnel oven, comprising a first furnace body, a second furnace body detachably fixed to one side of the first furnace body via a fixing device, a display screen fixedly mounted on the outer wall of one side of the first furnace body, temperature sensors symmetrically fixedly mounted on the inner walls of both the first and second furnace bodies, an aluminum strip penetrating through the interior of both the first and second furnace bodies, two push rod seats fixedly mounted at the top of the inner walls of both the first and second furnace bodies, a push rod fixedly mounted at the bottom end of the push rod seat, and a fixing frame fixedly mounted at the bottom end of the push rod.

[0006] Preferably, a first connecting block is fixedly provided at both ends of one side of the first furnace body, and a threaded hole is provided through one side of the first connecting block. A limiting ring and a silicone rubber sealing ring are fixedly provided on one side of the first furnace body, and the silicone rubber sealing ring is larger than the limiting ring. A second connecting block is fixedly provided at both ends of one side of the second furnace body, and a bolt is threadedly connected to the second connecting block. A limiting groove is provided through one side of the second furnace body. The fixing device includes a first connecting block, a threaded hole, a limiting ring, a silicone rubber sealing ring, a second connecting block, a bolt, and a limiting groove.

[0007] Preferably, the limiting ring of the first furnace body is inserted into the limiting groove of the second furnace body, the bolt of the second connecting block is threadedly connected to the threaded hole of the first connecting block, and the silicone rubber sealing ring of the first furnace body is tightly fitted to one side of the outer wall of the second furnace body.

[0008] Preferably, the second furnace body has a first connecting block of fixing device fixed at both ends on the other side, a limiting ring and a silicone rubber sealing ring fixed on the other side, and multiple furnace bodies can be fixed at the other end of the second furnace body by fixing device.

[0009] Preferably, the bottom end of the fixing frame is provided with multiple tube grooves, and multiple electric heating tubes are detachably provided in the tube grooves.

[0010] Preferably, the temperature sensor is used to receive and collect temperature data inside the furnace in real time. The display screen is electrically connected to the temperature sensor to receive the temperature data and display it visually. The display screen is equipped with a control module, which is electrically connected to the push rod seat. By operating the display screen, a displacement control signal can be sent to the push rod seat to drive the push rod to rise and fall in the vertical direction, thereby adjusting the distance between the heating tube and the aluminum strip of the bottom fixing bracket of the push rod to adapt to the heating distance adjustment under different temperature requirements.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model can freely splice furnace bodies of different lengths according to actual needs such as aluminum strip processing length and output through a fixing device, without the need to purchase special equipment separately for different production scenarios, which greatly improves equipment utilization and reduces the initial investment and equipment idle costs of enterprises.

[0013] 2. This utility model uses a built-in temperature sensor in the furnace body to collect temperature data of each segment in real time and display it clearly on the screen. The staff can intuitively monitor temperature changes. At the same time, the distance between the heating tube at the bottom of the fixing frame and the aluminum strip can be adjusted through the display screen to accurately control the heating temperature and uniformity of the aluminum strip, avoiding problems such as paint color difference and insufficient adhesion caused by temperature deviation, and improving the product qualification rate.

[0014] 3. This utility model differs from the traditional integrated temperature-controlled tunnel furnace by using a multi-section furnace body. The equipment can independently control the temperature of each section of the furnace body according to the temperature requirements of different processes in aluminum strip baking. With the precise adjustment of the distance between the electric heating tube and the aluminum strip, heat can be output as needed, avoiding ineffective heating and significantly reducing energy consumption such as electricity, which meets the energy-saving production needs of enterprises.
