Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber production equipment, and more specifically to an automatic expansion device for an air shaft of a carbon fiber take-up machine. Background Art

[0002] Carbon fiber is a new type of high-strength, high-modulus fiber material with a carbon content of more than 95%. It is made of organic fibers such as flaky graphite microcrystals stacked along the axial direction of the fiber. It is a microcrystalline graphite material obtained by carbonization and graphitization. Carbon fiber is "soft on the outside and hard on the inside" and is lighter than metallic aluminum.

[0003] When the carbon filament winder is winding or after winding, the winder involves two states: the air shaft is tightened and the winder is relaxed. However, in the prior art, before or after winding, the carbon filament winder needs to stop the winder first, and manually control the air shaft to tighten and relax the winder through buttons to ensure that the wind-up air shaft is tightened and the unwinding air shaft is relaxed. The operation is cumbersome, the degree of automation is low, and the electronic control is greatly affected by external factors, and the failure rate is relatively high. Therefore, a technical solution is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, this embodiment discloses an automatic tightening device for an air shaft of a carbon filament collecting machine, comprising a mounting plate 1, a turntable 2, an air shaft 3, a control valve 4, and a pressure plate assembly 6. The turntable 2 is rotatably mounted on the mounting plate 1. The figure is a back-to-back schematic diagram of this embodiment, and a motor 7 is installed on the back of the mounting plate 1. The outer periphery of the turntable 2 is provided with gear teeth. The output shaft of the motor 7 is installed with a gear corresponding to the gear teeth of the turntable 2, and the motor 7 can drive the turntable 2 to rotate.

[0026] like Figure 1 As shown, there are two pneumatic shafts 3, which are installed on the turntable 2. The two pneumatic shafts 3 are symmetrically arranged around the center of the turntable 2, and the two pneumatic shafts 3 respectively correspond to two workstations (a winding workstation and a reeling workstation) on the turntable 2. A detection head is installed at the corresponding workstation on the mounting plate 1 to detect whether the pneumatic shaft 3 has reached the corresponding workstation. The pneumatic shaft 3 passes through the turntable 2, and the part of the pneumatic shaft 3 on which the wire collection reel is installed is located on the front side of the mounting plate 1, and an air inlet pipe 31 is installed at one end of the pneumatic shaft 3 located on the back side of the mounting plate 1.

[0027] like Figure 1 , Figure 2 As shown, the control valve 4 is installed on the turntable 2 through a frame 5. The frame 5 is annular and is provided with a support plate 51. The support plate 51 extends along the radial direction of the turntable 2. The control valve 4 is installed at one end of the support plate 51 away from the center of the turntable 2. The control valve 4 is provided with a connecting plate 46. The connecting plate 46 is provided with a waist-shaped hole 461. The control valve 4 can be adjusted along the direction of the waist-shaped hole 461. The waist-shaped hole 461 has the same extension direction as the connecting plate 46. The control valve 4 can adjust its position in the radial direction of the turntable 2 through the waist-shaped hole 461.

[0028] like Figure 2 , Figure 3 As shown, the control valve 4 includes a valve plate 41, a valve body 42, a button 43, an air inlet 44 and an air outlet 45. The valve plate 41 includes a free end, and the free end can be close to or away from the valve body 42. The other end of the valve plate 41 is connected to the valve body 42 by a hinge. The hinged part of the valve plate 41 and the valve body 42 is installed with a torsion spring, which can maintain a certain angle of the valve plate 41 and reset it after rotation. The button 43 is installed on the side of the valve body 42 facing the valve plate 41. The air inlet 44 is connected to the air source, and the part where the air source and the air inlet 44 are connected is connected by a rotating joint. The air source and the air inlet 44 prevent the air pipe connected therebetween from rotating and entangled. The air outlet 45 is connected to the inflation shaft 3. Pressing the button 43 can trigger the air inlet 44 of the control valve 4 to be connected to the air outlet 45. The control valve 4 adopts a two-position three-way mechanical valve.

[0029] like Figure 2 , Figure 3 As shown, the pressure plate assembly 6 is installed on the mounting plate 1, and the pressure plate assembly 6 is located on the rotation path of the control valve 4. The pressure plate assembly 6 and the control valve 4 are located on the same side of the mounting plate 1. The pressure plate assembly 6 includes a bracket 61 and a pressing plate 62. The bracket 61 is fixedly installed on the mounting plate 1, and the pressing plate 62 is fixedly installed on the bracket 61. The pressing plate 62 is located on the outer side of the turntable 2. The pressing plate 62 can contact the control valve 4 and thus trigger the control valve 4. When the pressure plate assembly 6 triggers the control valve 4, the air inlet 44 is connected to the air outlet 45.

[0030] like Figure 2 , Figure 4As shown, the side of the pressing plate 62 facing the center of the turntable 2 is a pressing surface 621, and the pressing surface 621 is an arc surface. The pressing surface 621 and the turntable 2 are concentrically arranged. The free end of the valve plate 41 is installed with a roller 411, and the roller 411 is located on the side of the valve plate 41 away from the center of the turntable 2. One inflatable shaft 3 is connected to a control valve 4. When the inflatable shaft 3 rotates to the winding position, the control valve 4 corresponding to the inflatable shaft 3 at the winding position reaches the position of the pressure plate assembly 6, and the roller 411 of the valve plate 41 presses against the pressing surface 621 to trigger the control valve 4. When the pressure plate assembly 6 triggers the control valve 4, the pressing plate 62 presses against the valve plate 41, and the valve plate 41 presses against the button 43, so that the air inlet 44 is connected to the air outlet 45, so that the gas of the air source passes into the inflatable shaft 3, so that the inflatable shaft 3 can be wound and the reel can be removed.

[0031] More preferably, the pressure plate 62 includes two inclined surfaces 622, which are located at both ends of the pressure surface 621, and the outer ends of the inclined surfaces 622 gradually move away from the center of the turntable 2. The two inclined surfaces 622 can play a transition role when the roller 411 contacts the pressure plate 62, and guide the roller 411 to enter the pressure surface 621, so that the triggering of the control valve 4 and the pressure plate assembly 6 is more stable.

[0032] More preferably, the frame 5 is installed with a connecting pipe 52, which extends axially toward the turntable 2. The connecting pipe 52 is provided with an air inlet end 521 and an air outlet end 522. The air inlet end 521 is connected to the air outlet 45, and the air outlet end 522 is connected to the inflatable shaft 3. The connecting pipe 52 plays a role of connection transition. The air outlet 45 of the control valve 4 is far away from the air inlet pipe 31 of the inflatable shaft 3, and a transition connection needs to be made through the connecting pipe 52.

[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
