Description

Technical Field

[0001] The utility model relates to the technical field of fabric processing equipment, and particularly to an emergency air door and an oven. Background Art

[0002] An industrial oven controls the temperature of the working chamber by connecting a digital display instrument and a temperature sensor, and uses hot air circulation to dry materials. The hot air circulation system is divided into horizontal air supply and vertical air supply, both of which are professionally designed. The air source is driven by a motor to drive the air supply fan wheel, so that the blown air blows on the electric heating tube to form hot air. The hot air is sent into the working chamber of the industrial oven through the air duct, and the used hot air is sucked into the air duct again to become the air source for recycling and heating, greatly improving the temperature uniformity. The industrial oven has a uniquely designed strong air circulation system to ensure temperature stability. The temperature control system uses digital display temperature control, which is intuitive and eye-catching, and is equipped with a reliability protection device and over-temperature alarm.

[0028] The present utility model will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present utility model, but do not limit the present utility model in any form. It should be noted that those of ordinary skill in the art can make several changes and improvements without departing from the concept of the present utility model. These all belong to the protection scope of the present utility model.

[0029] Embodiment 1

[0030] As Figures 1 - 3As shown in the figure, a kind of emergency air door provided by the utility model includes: a frame 1, a door panel 2, a pull arm assembly and a driving device. The door panel 2 is arranged on the front of the frame 1. Two groups of pull arm assemblies are respectively arranged on two sides of the frame 1. The driving device is in transmission connection with the pull arm assembly. The door panel 2 can be close to or far away from the frame 1. The pull arm assembly includes: an auxiliary pull arm 4 and two pull arms 3. The two pull arms 3 are connected by the auxiliary pull arm 4. The middle part of the pull arm 3 is installed on the frame 1. One end of the pull arm 3 is rotationally connected with the door panel 2. The pull arm 3 can rotate around any connection point. The pull arm 3 includes a first pull arm 31 located between the frame 1 and the door panel 2. The first pull arm 31 is L-shaped.

[0031] The two groups of pull arm assemblies are symmetrically arranged on both sides of the frame 1.

[0032] The two pull arms 3 are arranged in parallel, and the two pull arms 3 are installed at the one-third points of the door panel 2.

[0033] The first pull arm 31 includes a vertical pull arm close to the frame 1 and a horizontal pull arm close to the door panel 2. The included angle between the vertical pull arm and the horizontal pull arm is 90°, and the included angle faces downward.

[0034] The pull arm 3 further includes a second pull arm 32 located between the frame 1 and the auxiliary pull arm 4. The second pull arm 32 is strip-shaped. The included angle between the second pull arm 32 and the vertical pull arm is an obtuse angle, and the included angle faces upward.

[0035] The shape of the pull arm 3 mainly considers strength and space occupation problems. Because the force when closing the door is downward, the 90° bending part is subjected to greater force and has higher strength. In other specific embodiments, other high-strength shape structures can be adopted.

[0036] The driving device includes a control device and two cylinders 5. The control device is respectively connected with the two cylinders 5. The two cylinders 5 are symmetrically arranged on both sides of the frame 1, and the two cylinders 5 can move synchronously.

[0037] An installation rod is arranged at the bottom of the frame 1. The two cylinders 5 are symmetrically installed at both ends of the installation rod. The central axis of the cylinder 5 is parallel to the plane where the pull arm assembly is located.

[0038] The output end of the cylinder 5 is connected with the connection point of the pull arm 3 and the auxiliary pull arm 4 through a connecting screw 6.

[0039] The output end of the cylinder 5 is connected with the upper pull arm 3.

[0040] The working process of this application is as follows: When it is necessary to open the air door, the control device controls the two cylinders 5 to move synchronously upward, driving the two sets of pull arm assemblies on both sides of the frame 1 to move synchronously, that is, driving the connection point between the upper pull arm 3 and the auxiliary pull arm 4 to move upward. Since the middle part of the pull arm 3 is installed on the frame 1, the pull arm 3 rotates around this connection point, and the other end of the pull arm 3, that is, the connection point with the door panel 2, is driven to move downward, so that the door panel 2 is separated from the frame 1 to open the air door. Similarly, when it is necessary to close the air door, the control device controls the two cylinders 5 to move synchronously downward and retract, driving the connection point between the upper pull arm 3 and the auxiliary pull arm 4 to move downward. Since the middle part of the pull arm 3 is installed on the frame 1, the pull arm 3 rotates around this connection point, and the other end of the pull arm 3, that is, the connection point with the door panel 2, is driven to move upward, so that the door panel 2 approaches and fits with the frame 1 to close the air door.

[0041] The structure of this application is simple, the operation is convenient, safe, and highly practical. It can open the door panel 2 in an extremely short time, allowing fresh air to enter the oven to achieve temperature reduction, greatly improving the safety of production, and thus improving work efficiency.

[0042] Embodiment 2

[0043] Based on Embodiment 1, an oven provided by the present utility model is installed with the emergency air door of Embodiment 1. By driving the driving device to drive the pull arm assembly to move, the door panel 2 can be quickly opened, allowing fresh air to enter the oven to achieve temperature reduction, and effectively avoiding the occurrence of situations such as fusing or catching fire when the temperature in the oven exceeds the melting point of the product during the product processing process, thus ensuring the safety of production work for subsequent work.
