Description

Technical Field

[0001] This utility model relates to the technical field of aluminum-plastic film production equipment, specifically to a multi-station aluminum-plastic film baking system. Background Technology

[0002] Aluminum-plastic film is typically a multilayer film composed of an outer nylon layer, an adhesive, an intermediate aluminum foil layer, an inner heat-sealing layer, and is mainly used as an encapsulation material for soft-pack lithium batteries. The production of aluminum-plastic film requires drying equipment to ensure the dryness of the finished product. Traditional drying equipment generally has multiple ovens. Because each oven uses an independent heat source, the manufacturing cost of the drying equipment is high, and the ovens cool down slowly, resulting in low production efficiency. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a multi-station aluminum-plastic film baking system that can use a single heat source to heat all ovens, reducing manufacturing costs while enabling rapid cooling of the ovens and improving production efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-station aluminum-plastic film baking system includes a heat source, a main air inlet pipe, and several ovens. The heat source delivers hot air to the main air inlet pipe. Each oven is connected to an air inlet branch pipe and an exhaust branch pipe. An air inlet fan is installed in the air inlet branch pipe. The air inlet branch pipe is connected to a first branch pipe and a second branch pipe. The input end of the first branch pipe is connected to the main air inlet pipe, and the input end of the second branch pipe is connected to atmospheric air or a cold air supply device. A first air valve actuator is installed at the connection between the first branch pipe and the second branch pipe. The first air valve actuator controls the air inlet branch pipe to connect with the first branch pipe and / or the second branch pipe.

[0006] By setting up a multi-station aluminum-plastic film baking system consisting of a heat source, a main air inlet pipe, and several ovens, during heating, the first air valve actuator controls the connection between the air inlet branch pipe and the first branch pipe. The hot air output from the heat source passes through the main air inlet pipe, the first branch pipe, and the air inlet branch pipe in sequence before entering the oven to heat the aluminum-plastic film inside the oven. During cooling, the first air valve actuator controls the connection between the air inlet branch pipe and the second branch pipe. The cold air passes through the second branch pipe and the air inlet branch pipe in sequence before entering the oven to quickly cool the aluminum-plastic film inside the oven. Thus, a single heat source is used to heat all ovens, reducing manufacturing costs. At the same time, the first air valve actuator can be used to achieve rapid cooling of the ovens, improving production efficiency.

[0007] As a preferred embodiment, the exhaust branch pipe is connected to a third branch pipe and a fourth branch pipe. The third branch pipe is used to exhaust air from the oven. The output end of the fourth branch pipe is connected to the second branch pipe. A second air valve actuator is provided at the connection between the third branch pipe and the fourth branch pipe. The second air valve actuator controls the exhaust branch pipe to connect with the third branch pipe and / or the fourth branch pipe.

[0008] As a preferred embodiment, the third branch pipe is connected to the exhaust main pipe.

[0009] As a preferred embodiment, the exhaust branch pipe is equipped with an exhaust fan.

[0010] As a preferred embodiment, the first air valve actuator is rotatably provided with an air damper, which can switch positions at the output end of the first branch pipe or the output end of the second branch pipe.

[0011] As a preferred embodiment, a control system is also included, wherein the oven is equipped with a temperature controller for detecting temperature differences, and the control system can control the first air valve actuator to operate based on the temperature information detected by the temperature controller.

[0012] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, by setting up a multi-station aluminum-plastic film baking system consisting of a heat source, an air inlet main pipe, and several ovens, during heating, the first air valve actuator controls the air inlet branch pipe to connect with the first branch pipe. The hot air output from the heat source passes through the air inlet main pipe, the first branch pipe, and the air inlet branch pipe in sequence before entering the oven to heat the aluminum-plastic film inside the oven. During cooling, the first air valve actuator controls the air inlet branch pipe to connect with the second branch pipe. The cold air passes through the second branch pipe and the air inlet branch pipe in sequence before entering the oven to rapidly cool the aluminum-plastic film inside the oven. Thus, a single heat source is used to heat all ovens, reducing manufacturing costs. At the same time, the first air valve actuator can be used to achieve rapid cooling of the ovens, improving production efficiency.

Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] like Figure 1-4 As shown, this utility model discloses a multi-station aluminum-plastic film baking system, including a heat source 10, an air inlet pipe 11, an air outlet pipe 12, and several ovens 20. For example, the number of ovens 20 is three, namely a first oven 201, a second oven 202, and a third oven 203. The heat source 10 delivers hot air to the air inlet pipe 11.

[0023] Each of the ovens 20 is connected to an air inlet branch pipe 21 and an air outlet branch pipe 22. An air inlet fan 23 is installed in the air inlet branch pipe 21. The function of the air inlet fan 23 is to supply air to the oven 20.

[0024] The air inlet branch pipe 21 is connected to a first branch pipe 211 and a second branch pipe 212. The input end of the first branch pipe 211 is connected to the main air inlet pipe 11, and the input end of the second branch pipe 212 is connected to the atmosphere or a cold air supply device. A first air valve actuator 24 is provided at the connection between the first branch pipe 211 and the second branch pipe 212. The first air valve actuator 24 controls the air inlet branch pipe 21 to be connected to the first branch pipe 211 and / or the second branch pipe 212.

[0025] The exhaust branch pipe 22 is connected to a third branch pipe 221 and a fourth branch pipe 222. The third branch pipe 221 is used to exhaust air from the oven 20. Specifically, the output end of the third branch pipe 221 is connected to the main exhaust pipe 12, and the output end of the fourth branch pipe 222 is connected to the second branch pipe 212. A second air valve actuator 25 is provided at the connection between the third branch pipe 221 and the fourth branch pipe 222. The second air valve actuator 25 controls the exhaust branch pipe 22 to connect with the third branch pipe 221 and / or the fourth branch pipe 222. By setting the third branch pipe 221, the fourth branch pipe 222 and the second air valve actuator 25, hot air can be circulated in the oven 20 with less energy loss. At the same time, hot air and cold air can be mixed to keep the required temperature in the oven 20 constant.

[0026] The exhaust branch pipe 22 is equipped with an exhaust fan 26, which is used to exhaust air from the oven 20.

[0027] The first air valve actuator 24 is rotatably provided with an air damper 241. The air damper 241 can switch positions at the output end of the first branch pipe 211 or the output end of the second branch pipe 212. It is understood that the second air valve actuator 25 has the same structure and principle as the first air valve actuator 24, so it will not be described in detail.

[0028] This utility model also includes a control system (not shown). The oven 20 is equipped with a temperature controller (not shown) for detecting temperature differences. The control system can control the first air valve actuator 24 to work according to the temperature information detected by the temperature controller. For example, when the temperature controller detects a large temperature difference between the temperature inside the oven 20 and the required temperature, the control system controls the air damper 241 on the first air valve actuator 24 to open to a suitable position, thereby adjusting the hot air intake or cold air intake, and thus adjusting the temperature inside the oven 20 to the required temperature.

[0029] The working principle of this utility model:

[0030] First oven 201: Air inlet branch pipe 21 is connected to first branch pipe 211, and air outlet branch pipe 22 is connected to third branch pipe 221. The hot air output from heat source 10 passes through air inlet main pipe 11, first branch pipe 211, air inlet branch pipe 21, first oven 201, air outlet branch pipe 22, and third branch pipe 221 in sequence and is then discharged to the outside from air outlet main pipe 12. At this time, the first oven 201 is in a continuous heating state.

[0031] Second oven 202: Inlet branch pipe 21 is connected to second branch pipe 212, and exhaust branch pipe 22 is connected to third branch pipe 221. Hot air output from heat source 10 does not enter second oven 202. Air in the atmosphere passes through second branch pipe 212, inlet branch pipe 21, second oven 202, exhaust branch pipe 22, and third branch pipe 221 in sequence and is then discharged to the outside through exhaust main pipe 12. At this time, second oven 202 is in a cooling state.

[0032] The third oven 203: the air inlet branch pipe 21 is connected to the first branch pipe 211 and the second branch pipe 212, and the exhaust branch pipe 22 is connected to the third branch pipe 221 and the fourth branch pipe 222. The hot air output from the heat source 10 passes through the main air inlet pipe 11, the first branch pipe 211, the air inlet branch pipe 21, the third oven 203, the exhaust branch pipe 22, and the third branch pipe 221 in sequence, and is then discharged to the outside from the main exhaust pipe 12. At the same time, some of the hot air in the exhaust branch pipe 22 passes through the fourth branch pipe 222, the second branch pipe 212, and the air inlet branch pipe 21 in sequence and enters the third oven 203. At this time, the hot air and cold air are mixed and enter the oven 20, so that the third oven 203 is in a state of circulating heating.

[0033] In summary, this utility model, by setting up a multi-station aluminum-plastic film baking system consisting of a heat source 10, an air inlet main pipe 11, and several ovens 20, allows for heating. During heating, the first air valve actuator 24 controls the air inlet branch pipe 21 to connect with the first branch pipe 211. The hot air output from the heat source 10 passes through the air inlet main pipe 11, the first branch pipe 211, and the air inlet branch pipe 21 in sequence before entering the oven 20 to heat the aluminum-plastic film inside the oven 20. During cooling, the first air valve actuator 24 controls the air inlet branch pipe 21 to connect with the second branch pipe 212. The cold air passes through the second branch pipe 212 and the air inlet branch pipe 21 in sequence before entering the oven 20 to rapidly cool the aluminum-plastic film inside the oven 20. Thus, a single heat source 10 can heat all the ovens 20, reducing manufacturing costs. At the same time, the first air valve actuator 24 can be used to achieve rapid cooling of the ovens 20, improving production efficiency.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
