Description

[Technical Field]

[0001] This utility model relates to an air damper control system applied to the built-in air duct of a setting machine. [Background Technology]

[0002] The existing shaping machine uses an air damper in the oven air inlet to control the opening and closing of the air duct. However, the existing air damper control system requires an external motor, an external motor driver, and an external drive gear set to control the rotation of the air damper to adjust the opening and closing. Since the motor, motor driver, and drive gear set are all set independently and are not tightly connected, the opening angle of the air damper is prone to errors, resulting in low opening accuracy of the air damper. [Utility Model Content]

[0003] This invention overcomes the shortcomings of the prior art and provides an air damper control system applied to the built-in air duct of a stenter.

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

[0005] A damper control system for use in the built-in air duct of a setting machine is characterized by comprising an operating console for sending control commands for the damper rotation analog signal, and a damper baffle disposed inside the oven of the setting machine and opposite to the air inlet of the air duct. A rotating rod with its other end extending out of the air duct is connected to the damper baffle, and an analog damper actuator is connected to the extended end of the rotating rod for receiving the control command for the damper rotation analog signal sent by the operating console and driving the rotating rod to rotate so that the damper baffle rotates.

An actuator housing is provided on the front side of the mounting base.

The shaft end of the micro motor is connected to the input end of the reduction gear assembly, the output end of the reduction gear assembly is connected to the transmission wheel, and the actuator control module is connected to the micro motor and drives the micro motor to rotate according to the analog signal control commands.

[0008] The air damper control system applied to the built-in air duct of a setting machine as described above is characterized in that: a rotating component is sleeved on a rotating rod, and a locking component is provided on the rotating component to lock the rotating rod on the rotating component.

[0013] The beneficial effects of this utility model are:

[0014] This invention features an analog damper actuator connected to the extended end of the rotating rod. This actuator receives analog control commands for damper rotation from the control panel and drives the rotating rod to rotate, thereby causing the damper baffle to rotate. After the control panel sends the analog control command for damper rotation, the analog damper actuator can precisely drive the rotating rod to rotate, thus precisely adjusting the opening angle of the damper baffle. Simultaneously, the analog damper actuator contains a micro motor and a reduction gear assembly that are tightly connected, allowing the micro motor, reduction gear assembly, and transmission wheel to be tightly connected to each other, achieving precise adjustment of the opening angle of the damper baffle.

[0017] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0018] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0019] like Figure 1-2 As shown, an air damper control system applied to the built-in air duct of a setting machine includes an operating console for sending air damper rotation analog signal control commands, and an air damper baffle 1 installed inside the setting machine oven and opposite the air duct inlet. A rotating rod 2, with its other end extending out of the air duct, is connected to the air damper baffle 1. The extended end of the rotating rod 2 is connected to an analog damper actuator 3, which receives the air damper rotation analog signal control commands sent by the operating console and drives the rotating rod 2 to rotate, thereby rotating the air damper baffle 1. In actual use, the operating console sends air damper rotation analog signal control commands to the analog damper actuator 3. After receiving the air damper rotation analog signal control commands, the analog damper actuator 3 drives the rotating rod 2 and the air damper baffle 1 to precisely rotate to the set angle, greatly improving the accuracy of the air damper baffle 1 angle adjustment.

[0020] like Figure 1-2 As shown, the analog damper actuator 3 includes a mounting base 31, which is equipped with an actuator bearing. The extended end of the rotating rod 2 is mounted on the actuator bearing and connected to a transmission wheel 32. An actuator housing 33 is located on the front side of the mounting base 31. Inside the actuator housing 33 are a micro motor, a reduction gear assembly, and an actuator control module that connects to the control panel to receive analog signal control commands. The micro motor shaft is connected to the input end of the reduction gear assembly, and the output end of the reduction gear assembly is connected to the transmission wheel 32. The actuator control module is connected to the micro motor and drives it to rotate according to the analog signal control commands. A rotating component 34, which rotates with the rotating rod 2, is connected to the extended end of the rotating rod 2, and the transmission wheel 32 is mounted on the rotating component 34. When adjusting the angle of the damper 1, the actuator control module in the analog damper actuator 3 controls the micro motor to rotate, and through the reduction gear assembly and the transmission wheel 32, drives the rotating rod 2 and the damper 1 to rotate precisely to the set angle. In this case, the analog damper actuator 3 is equipped with a micro motor and a reduction gear assembly that are tightly connected, which can make the micro motor, the reduction gear assembly and the transmission wheel tightly connected to each other, so as to achieve precise adjustment of the opening angle of the damper.

[0021] like Figure 1-2As shown, a pointer 35 is provided on the rotating part 34, and an angle scale 36 is provided on the upper side of the actuator housing 33. The rotation angle of the air damper 1 in the air duct can be indicated by the angle scale 36 pointed to by the pointer 35.

[0022] like Figure 1-2 As shown, the rotating component 34 is sleeved on the rotating rod 2, and the rotating component 34 is provided with a locking component 37 to lock the rotating rod 2 on the rotating component 34. The rotating component 34 and the rotating rod 2 are locked together by the locking component 37.

[0023] like Figure 1-2 As shown, the actuator housing 33 is located on the front side of the mounting base 31, below the rotating member 34, and the angle scale 36 is located on the front side of the actuator housing 33 near the rotating member 34. The upper side of the actuator housing 33 is provided with a housing recess 38 for the pointer 35 to rotate, so that the pointer 35 can accurately indicate the angle scale 36 of the air damper 1 rotation.

[0024] like Figure 1-2 As shown, the rotating rod 2 is provided with mounting parts 4 on both sides of the air damper 1 for mounting the rotating rod 2 on the air duct. The mounting parts 4 on both sides are provided with rotating seats 41 that are connected to the rotating rod 2 and can make the rotating rod 2 rotate, so that the rotating rod 2 is stably installed in the air duct and can be rotated and opened and closed to adjust the angle in the air duct.

[0025] like Figure 1-2 As shown, the rotating rod 2 is provided with an air damper connector 5, and the air damper baffle 1 is set on the air damper connector 5, so that the air damper connector 5 is stably installed on the rotating rod 2.

[0026] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
