Description

Technical Field

[0001] The utility model belongs to the field of XPE production, in particular to an automatic air door used in an XPE production line. Background Art

[0002] XPE production line refers to a production line used to produce chemically cross-linked polyethylene foam (Crosslinked Polyethylene Foam, referred to as XPE). XPE is a material made by adding a cross-linking agent and a foaming agent to low-density polyethylene resin and then undergoing a high-temperature continuous foaming process. It has a wide range of uses.

[0003] In an XPE production line, the process includes extrusion of mother sheets and foam molding, which require specific temperatures and environments. Therefore, a ventilation system is needed to control the temperature and air quality on the production line. In particular, during the foam molding process, the use of horizontal or vertical furnaces generates a large amount of heat, which needs to be discharged through ventilation ducts to maintain stable operation of the production line and the safety of operators. Damper control is generally used in ventilation ducts to control the flow within the ducts.

[0004] However, the damper in the original design adopts the whole plate fan blade + manual mode, which has the problem of uneven flow regulation and low efficiency. Therefore, it is urgent to design a new type of automatic damper to solve the above problems. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide an automatic damper for use in an XPE production line, which can automatically control the air volume in the pipeline. By driving the connecting rod mechanism through a reducer, the wind shield can be rotated from 0° to 90°, and the damper can be controlled from fully closed to fully open, thereby improving efficiency.

[0006] Technical solution: In order to achieve the above-mentioned purpose, the utility model provides an automatic damper for use in an XPE production line, comprising a first wind shield mounting rod, a group of second wind shield mounting rods, three groups of wind shields, a connecting rod mechanism and a driving mechanism; the first wind shield mounting rod is arranged through the ventilation duct; the second wind shield mounting rod is arranged through the ventilation duct, and is respectively located above and below the first wind shield mounting rod; the wind shield is arranged on the first wind shield mounting rod and the second wind shield mounting rod, and can rotate axially with the first wind shield mounting rod and the second wind shield mounting rod; the connecting rod mechanism is arranged outside the ventilation duct and is located beside the first wind shield mounting rod; the connecting rod mechanism is connected to the first wind shield mounting rod and the second wind shield mounting rod, and can control the second wind shield mounting rod to rotate axially in conjunction with the first wind shield mounting rod; the driving mechanism is arranged outside the ventilation duct and is located on the side of the connecting rod mechanism away from the first wind shield mounting rod.

[0007] Furthermore, the upper and lower edges of the windshield are respectively provided with concave and convex structures. When the damper is fully closed, the concave and convex structures on both edges of the windshield cooperate with each other to ensure airtightness.

[0008] Furthermore, the linkage mechanism includes a connecting rod and three sets of linkage components; the connecting rod is connected to the first windshield mounting rod and the second windshield mounting rod through the three sets of linkage components. The connecting rod cooperates with the linkage components to ensure the linkage of the device and the uniformity of the air door flow;

[0009] Furthermore, the linkage assembly includes a linkage rod, a cotter pin, and a rotating pin; the linkage rod is vertically arranged on a side of the coupling rod near the first windshield mounting rod; the cotter pin has an open end connected to the linkage rod via a rotating pin; the closed ends of the three cotter pins (422) are respectively arranged on the first windshield mounting rod and the second windshield mounting rod. The linkage rod provides force transmission for the linkage rotation; the cotter pin provides space for the linkage rotation; and the rotating pin provides a rotating shaft for the linkage rotation.

[0010] Furthermore, the drive mechanism includes a speed reducer and a servo motor. The speed reducer is located on the side of the coupling rod away from the first windshield mounting rod and is connected to the first windshield mounting rod. The servo motor is located adjacent to the speed reducer and is connected to the speed reducer. The speed reducer cooperates with the servo motor to reduce the servo motor's output speed, making it suitable for the transmission equipment requirements, while also providing greater torque output and improving work efficiency.

[0011] Furthermore, the reducer is connected to the ventilation duct via a bracket, which provides support for the installation of the reducer and ensures its stability.

[0012] Furthermore, a washer is provided between the reducer and the bracket to protect the reducer and reduce vibration damage in the structure.

[0013] Furthermore, a shaft sleeve is provided at the connection between the second windshield mounting rod and the ventilation duct, which strengthens the connection and reduces the friction between the second windshield mounting rod and the ventilation duct, thereby facilitating the linked rotation.

[0014] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0015] 1. This utility model is an automatic damper used in an XPE production line. It can control the air volume in the pipeline through a connecting rod mechanism to ensure uniform flow.

[0016] 2. The utility model is an automatic damper used in an XPE production line.
