Description

Technical Field

[0001] The utility model relates to the technical field of spinning equipment, and particularly relates to a TMT air valve control device. Background Art

[0002] When the air box on the spinning box body conducts air supply and cooling through the air supply pipeline, the air pressure is controlled by the TMT air valve control device. The current TMT air valve control device is controlled by a panel hand controller to control the air valve feedback controller, so that the air valve motor operates, thereby controlling the opening and closing angle of the air valve, so that it can be adjusted to the air pressure required for production. Due to the aging of internal electronic components over the years, there are many current failures, although it can be repaired by itself. However, due to the high temperature of the spinning environment, the plastic of the hand controller panel is oxidized and damaged at an accelerated rate, resulting in abnormal installation and use. It can only be replaced by purchasing a new hand controller, which is costly. And in the case of sudden failure without turning off the power of the air valve control, the air valve may act freely and out of control, resulting in unstable product quality. Summary of the Invention

[0003] In order to solve certain or some technical problems existing in the prior art, the purpose of this application is to provide a TMT air valve control device, which solves the situation that the air pressure fluctuates due to sudden failure of the air valve, resulting in unstable product quality, and at the same time saves maintenance expenses.

[0004] In order to solve the above-mentioned existing technical problems, the following technical solutions are adopted in this application:

[0005] A TMT air valve control device includes an air cylinder, a valve body arranged on the air inlet pipeline of the air cylinder, an actuator arranged on one side of the valve body, and a controller for controlling the forward and reverse rotation of the actuator. The controller includes a box body, a metal panel arranged on the box body, and a forward and reverse rotation knob arranged on the metal panel. A quick plug interface for connecting a wind pressure gauge is also arranged on one side of the air cylinder. The opening and closing degree of the valve body is controlled by the forward and reverse rotation knob, and the opening and closing degree of the valve body is adjusted according to the reading of the wind pressure gauge externally connected to the quick plug interface.

[0006] Preferably, a circuit breaker is further arranged on the metal panel, and the circuit on the forward and reverse rotation knob is energized and controlled after being connected through the circuit breaker.

[0007] Preferably, the forward and reverse rotation knob is a three-position knob, and the forward and reverse rotation knob is used to control the forward rotation, stop, and reverse rotation of the forward and reverse rotation knob.

[0008] Preferably, the circuit breaker adopts a spring-back button.

[0009] Preferably, the forward and reverse rotation knob and the spring-back button are connected in series on the live wire of the actuator, and the live wire is connected after the spring-back button is pressed.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. Replace the plastic hand-operated panel in the existing controller with a metal panel, thereby improving the service life of the panel on the box body during use, avoiding the situation of easy aging caused by high-temperature environment, and having low replacement and maintenance costs.

[0012] 2. The actuator is directly controlled by a forward and reverse knob without passing through an internal feedback controller. At the same time, the opening and closing degree of the valve body is adjusted according to the reading of the air pressure gauge externally connected to the quick-connect interface, so as to achieve precise control of the air pressure in the air duct and solve the problems of difficult maintenance and high maintenance costs existing in the existing internal feedback controller.

[0013] 3. Through the dual control of the circuit breaker and the forward and reverse knob, it can effectively avoid the situation that the air valve motor runs due to accidental touch of the forward and reverse knob, avoid air pressure fluctuations, and also avoid the situation that the air valve moves freely due to sudden failure when the air valve control power supply is not turned off, making the product quality more stable.

[0017] Next, in combination with the drawings and specific embodiments, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0018] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0019] The terms "first", "second", etc. in this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited.

[0020] As Figure 1 and Figure 2 As shown, a TMT air valve control device includes an air duct 4, a valve body 1 provided on the air inlet pipe 3 of the air duct 4, an actuator 2 provided on one side of the valve body 1, and a controller 10 for controlling the forward and reverse rotation of the actuator 2. The controller 10 includes a box body 9, a metal panel 8 provided on the box body 9, and a forward and reverse rotation knob 6 provided on the metal panel 8. A quick plug interface 5 for connecting a wind pressure gauge is also provided on one side of the air duct 4. The opening and closing degree of the valve body 1 is controlled by the forward and reverse rotation knob 6, and the opening and closing degree of the valve body 1 is adjusted according to the reading of the wind pressure gauge externally connected to the quick plug interface 5.

[0021] When retrofitting the existing TMT air valve control device, the plastic hand-operated panel on the box body 9 and the internal feedback controller 10 in the existing controller 10 are removed, and then the plastic hand-operated panel is replaced with a metal panel 8, so as to improve the service life of the panel on the box body 9 during use, reduce the occurrence of faults, and avoid the situation of easy aging caused by high-temperature environment. The replacement and maintenance costs are low. The control of the actuator 2 is controlled by a forward and reverse rotation knob 6 and no longer passes through the internal feedback controller 10. At the same time, a quick plug interface 5 for connecting a wind pressure gauge is installed on one side of the air duct 4. The opening and closing of the valve body 1 are controlled by the forward and reverse rotation knob 6, and the opening and closing degree of the valve body 1 is adjusted according to the reading of the wind pressure gauge externally connected to the quick plug interface 5. Thus, while achieving precise control of the wind pressure in the air duct 4, the problems of difficult maintenance and high maintenance costs existing in the existing internal feedback controller 10 are also solved.

[0022] Further improved, the forward and reverse rotation knob 6 is a three-position knob, and the forward and reverse rotation knob 6 is used to control the forward rotation, stop, and reverse rotation of the forward and reverse rotation knob 6.

[0023] The forward and reverse knob 6 is a three - position knob. The three positions of the forward and reverse knob 6 are forward rotation, stop, and reverse rotation. When controlling the forward and reverse rotation of the motor in the actuator 2, the control method is simpler. That is, when the forward and reverse knob 6 is in the middle position, it is in the stop state. Rotating it in two opposite directions is the forward and reverse rotation of the motor. It is less likely to be damaged during control, and the maintenance and replacement costs are lower after damage, and it is convenient to purchase accessories.

[0024] Further improvement is that a circuit breaker 7 is also provided on the metal panel 8, and the circuit on the forward and reverse knob 6 is energized and controlled after being connected through the circuit breaker 7.

[0025] A circuit breaker 7 is also added on the metal panel 8. The circuit on the forward and reverse knob 6 is energized and controlled after being connected through the circuit breaker 7. Through the dual control of the circuit breaker 7 and the forward and reverse knob 6, it can effectively avoid the situation where the air valve motor runs due to accidentally touching the forward and reverse knob 6, avoid the fluctuation of the wind pressure, and at the same time avoid the situation where the air valve moves freely due to sudden failure when the air valve control power supply is not turned off, making the product quality more stable.

[0026] Even further improvement is that the circuit breaker 7 uses a spring - back button.

[0027] The circuit breaker 7 uses a spring - back button. When it is necessary to control the opening and closing of the valve body 1, the spring - back button is pressed to connect the power supply. When the wind pressure adjustment is completed, releasing the finger can quickly cut off the power supply, thus avoiding the wind pressure error caused by the time difference of the rotation of the forward and reverse knob 6, making the wind pressure more accurate during control. During operation, after pressing the spring - back button with one hand, the other hand rotates the forward and reverse knob 6. Rotating it to the left is forward rotation, to the right is reverse rotation, and no action in the middle. When adjusting the wind pressure, insert the wind pressure gauge into the quick - plug interface 5, manually operate the valve body 1 to rotate, and finally the wind pressure is based on the reading of the wind pressure gauge.

[0028] Even further improvement is that the forward and reverse knob 6 and the spring - back button are connected in series on the live wire of the actuator 2, and the live wire is connected after the spring - back button is pressed.

[0029] The forward and reverse knob 6 and the spring - back button are connected in series on the live wire of the actuator 2. During control, the principle is as follows: Press the spring - back button to connect the live wire L, which flows to the common end of the forward and reverse knob 6. Rotate the forward and reverse knob 6 to switch the power supply at both ends of the capacitor in the actuator 2 for forward and reverse control. Among them, the neutral wire N is directly connected to the common end of the actuator 2. Through this improvement, the problem of unstable product quality caused by the fluctuation of the wind pressure due to the sudden failure of the air valve is solved, and at the same time, the maintenance cost is reduced and the maintenance expenses are saved.

[0030] The above embodiments are only preferred embodiments of the present application, and the scope of protection of the present application cannot be limited thereby. Any non-substantive changes and substitutions made by those skilled in the art based on the present application fall within the scope of protection required by the present application.
