Description

Technical Field

[0001] The present application belongs to the technical field of glass fiber drawing machines, and specifically relates to a rear-end disc-type drawing machine head capable of automatically adjusting online to avoid a drawing resonance area. Background Art

[0002] Due to the complexity of the glass fiber drawing process, the wide variety of varieties, and the large speed span, resonance is inevitable when the drawing machine head rotates. In particular, the Teflon bobbin is made of circumferential superposition and bonding, and the imbalance is large. If several bobbins are installed on a line, it is difficult for the head to overcome the resonance. If it operates in this section, it will shorten the service life of the bearings or even damage them, and cause various other problems caused by vibration.

[0003] The solution to this problem is usually to select a certain speed range based on the user's wire drawing process to avoid the resonance area. Some users choose a single process to avoid the resonance area for wire drawing, so basically two types of machines are used, namely high-speed and low-speed wire drawing machines. In other words, users have to increase their investment, but some so-called high-speed and low-speed models on the market have not completely overcome the resonance problem, which causes great trouble to users.

[0004] Please refer to our company's prior Chinese patent: A Machine Head Soft Support Rigidity Adjustment Mechanism, Publication No.: CN214299890U. Its disadvantage is that a specific speed range must be selected to manually adjust the machine head support rigidity to the appropriate operating range to avoid the resonance zone. However, this selective manual adjustment method is no longer sufficient for the current manufacturing of high-end composite materials. Due to the high line speeds of high-end products and the long yarn lengths (i.e., large yarn packages with small inner diameters and extra-large outer diameters), the difference between the starting and ending speeds is large, resulting in the manual adjustment range not being able to meet the entire operating range.

[0027] Beneficial technical effects:

[0028] 1. This application requests patent protection for a rear-end disc-type wire drawing machine head that can automatically adjust online to avoid the wire drawing resonance area. When the head is operating normally, the bearing seat, front and rear seats, cylinder body, piston, and rear-end disc form an online rigid adjustment mechanism for the head soft support.

[0029] Vibration sensors can detect die vibration in real time and provide feedback to the PLC control. A proportional valve PID is then used to adjust gas flow and / or pressure, enabling online real-time data acquisition and exchange. This dynamically controls die rigidity on the bearing seat to adjust the die, keeping die vibration within an acceptable range. This allows for flexible adaptation to the varying speed requirements of the wire drawing machine, enabling dynamic, closed-loop adjustment of die rigidity to meet actual production needs.

[0030] 2. The die head of the rear-end disc-type wire drawing machine disclosed in this application can adjust the die head rigidity in both the axial direction (via a vibration-damping component disposed between the piston and the rear seat) and the radial direction (via a vibration-damping component disposed between the front and rear seats and the bearing seat). This helps ensure the effective adjustment of the die head rigidity.

[0040] Direction convention: In this application, the side where the motor is located on the wire drawing machine head is the back, and the opposite side is the front.

[0041] Explanation of terminology: Rigidity is a technical term used when discussing the vibration of the machine head. The rigidity of the machine head is related to the vibration of the machine head and the speed of the machine head.

[0042] See also Figure 1 , the rear end disc drawing machine head that can automatically adjust online to avoid the drawing resonance area includes:

[0043] Machine head spindle 10;

[0044] The bearing seat 20 is provided with a spindle assembly hole, and the head spindle 10 is installed in the spindle assembly hole;

[0045] The cylinder body 30 is disposed on the bearing seat 20 and is provided with a piston chamber 310 and an air filling port 320 ; the air filling port 320 is connected to the piston chamber 310 and is used to supply air to the piston chamber 310 ;

[0046] The piston 40 is disposed in the piston chamber 310 and is movable in the piston chamber 310 under the action of compressed air;

[0047] The rear seat 50 is disposed on the bearing seat 20 and at least part of its structure is opposite to the piston 40. The piston 40 can be pressed against the rear seat 50 under the action of compressed air, that is, the piston 40 can squeeze the rear seat 50 under the action of compressed air.

[0048] The vibration-damping component 60 is provided on the rear seat 50 for cooperating with the piston 40 and can be a vibration-damping ring, a vibration-damping block, a vibration-damping ring or a vibration-damping sleeve.

[0049] Air is supplied to the piston chamber 310 from the inflation port 320; gradually increasing the air pressure of the compressed air can cause the piston 40 to gradually press the rear seat 50 through the vibration-damping component 60, thereby achieving the purpose of increasing the rigidity of the machine head; gradually reducing the pressure of the compressed air can cause the piston 40 to gradually loosen the rear seat 50 of the piston 40 through the vibration-damping component 60, thereby achieving the purpose of gradually reducing the rigidity of the machine head.

[0050] Increasing die head rigidity can reduce vibration and noise in the die system and improve equipment precision. However, excessive rigidity can lead to increased friction and elevated temperatures. Maintaining die head rigidity within an appropriate range is beneficial. Because different drawing speeds require different rigidity ranges, existing solutions that pre-adjust die head rigidity are not suitable for actual production needs.

[0051] The present application discloses a rear-end disc-type wire drawing machine head that can automatically adjust online to avoid the wire drawing resonance area. When the head is operating normally, the bearing seat 20, cylinder body 30, piston 40, back seat 50, and vibration reduction component 60 form a soft support online rigidity adjustment mechanism. The vibration sensor can detect the vibration of the head in real time and feed it back to the PLC control, and a proportional valve PID is used to adjust the gas flow and / or air pressure to achieve online real-time data collection and exchange, dynamically control the head rigidity adjustment mechanism on the bearing seat, and always control the head vibration within an acceptable range. This makes it possible to flexibly adapt to a large range of speed changes in the wire drawing machine, adjust the head rigidity in real time and dynamically, and meet the actual needs of production.
