Description

Technical Field

[0001] The present application belongs to the technical field of glass fiber production equipment, and specifically relates to a modular structure of a sleeve-type drawing machine head. Background Art

[0002] In glass fiber drawing production, there are typically two types of drawing machines: direct yarn drawing machines and cake yarn drawing machines. These machines have varying speeds, and high-speed centrifugal forces are significant. Direct yarn drawing machines, on the other hand, have a smaller head diameter, and the expansion and contraction of the sheet is primarily controlled by the cone sleeves at both ends. The middle cone sleeve, however, has limited space and thrust, so it can only serve as an auxiliary extension. The cone sleeves must also be symmetrically arranged, taking up a significant amount of space. Conversely, cake yarn drawing machines have a larger head diameter, typically featuring a large, long aluminum rotor. The front half is hollowed out, leaving the middle of the back half fixed to the spindle taper. The head's length is extended by the aluminum rotor to match the expansion sheet. However, the longer aluminum rotor and expansion sheet are particularly difficult to machine, especially the aluminum rotor, which requires complex processes such as deep hole drilling, taper turning, T-slot milling, and stress relief machining. The rotor is prone to damage, requiring a significant workload and difficult to guarantee quality. This presents particular challenges for users in terms of maintenance, as the overly long and heavy aluminum rotor is difficult to assemble and disassemble, requiring stringent requirements.

[0003] At the same time, if the length of the expansion piece is too long, the rigidity of the middle part will inevitably be affected. The existing expansion piece telescopic mechanism is prone to soft waist due to insufficient holding force. Summary of the Invention

[0053] The upper thread ring 20 is provided with a sleeve connection portion, which is provided with a sleeve connection hole; the sleeve-type aluminum rotating cylinder 60 is provided with an upper thread ring assembly screw hole; the upper thread ring 20 is fixedly connected through the sleeve connection hole and the upper thread ring assembly screw hole.

[0055] The use of a socket-type segmented aluminum rotor not only allows for the arbitrary assembly of multiple pulling heads through modular production and assembly in a building block manner, but also avoids the technical problems of difficult processing of extra-long aluminum rotors, the inability to guarantee processing quality, and the difficulty of disassembly during assembly and maintenance.

[0056] By arranging telescopic mechanism mounting positions 70 and sheet expansion telescopic mechanisms 80 between the upper wire ring 20 and the sleeved aluminum rotor 60, between the pull rod seat 30 and the aluminum rotor on the shaft 50, between the aluminum rotor on the shaft 50 and the sleeved aluminum rotor 60, and between every two adjacent sleeved aluminum rotors 60, it is possible to form multi-point supporting forces on the expanding sheet in the length direction of the expanding sheet, thereby avoiding the soft waist phenomenon that often occurs in long expanding sheets on existing long machine heads, and at the same time allowing the lightweight development of the expanding sheet.

[0057] To accommodate the operation of the extra-long machine head, this application uses a lightweight thermal expansion plate 40. The thermal expansion plate 40 is snap-fitted onto the on-axis aluminum rotor 50 and the sleeve-type aluminum rotor 60. The on-axis aluminum rotor 50 and the sleeve-type aluminum rotor 60 are provided with snap-fit ​​positions, and the connection portion of the thermal expansion plate 40 has a structure that matches the snap-fit ​​position. When the thermal expansion plate 40 is snap-fitted into the snap-fit ​​position, this snap-fit ​​connection can prevent the thermal expansion plate 40 from falling off in the radial direction. For the snap-fit ​​connection between the aluminum rotor and the expansion plate, please refer to the Chinese patent: A cone sleeve support device for the machine head expansion plate (publication number CN213803526U).

[0058] The thermal expansion plate 40 is provided with expansion spring slots 410 and expansion bridge slots 420. The expansion spring slots 410 are located at the front and rear ends of the thermal expansion plate 40. The expansion bridge slots 420 are evenly distributed along the length of the thermal expansion plate 40, and each expansion bridge slot 420 corresponds to a telescopic mechanism mounting position 70 and a telescopic mechanism 80.

[0059] The expansion and retraction mechanism 80 includes a piston ring 810, a ramp slider ring 820, a connecting rod slider 830, a connecting rod 840, a slider ring top spring 850, and a slider tension spring 860. The top spring seat holes 710, the connecting rod hole 720, and the piston cavity 730 are provided on both sides of the expansion and retraction mechanism mounting position 70.

[0060] The piston ring 810 is disposed in the piston cavity 730 , and the ramp slider ring 820 is disposed in the telescopic mechanism mounting position 70 and is in contact with and cooperates with the piston ring 810 .

[0061] The ramp slider ring 820 is provided with a plurality of ramp slider grooves 8210, and the connecting rod slider 830 is provided with a ramp matching portion 8310. The connecting rod slider 830 is assembled in the ramp slider groove 8210 and the ramp matching portion 8310 and the groove bottom of the ramp slider groove 8210 can form a sliding fit.

[0062] Connecting rod slider 830 is provided with a rod head accommodating portion 8320. One end of connecting rod 840 is movably connected to rod head accommodating portion 8320, and the other end of connecting rod 840 is movably connected to connecting rod hole 720. The opening of rod head accommodating portion 8320 is provided with a rod head movable opening 8340, and the opening of connecting rod hole 720 is provided with a connecting rod movable opening 740. Connecting rod 840 includes a connecting rod portion 8410 and connecting rod heads 8420 provided at both ends of connecting rod portion 8410. The connecting rod heads 8420 at both ends of connecting rod portion 8410 are movably assembled in the rod head accommodating portion 8320 and the connecting rod hole 720, respectively.

[0063] The ramp slider ring 820 is provided with a top spring insertion hole 8220, and the two ends of the slider ring top spring 850 are respectively assembled in the top spring seat hole 710 and the top spring insertion hole 8220. The slider ring top spring 850 acts on the side of the ramp slider ring 820 that is different from the piston ring 810.

[0064] The connecting rod slider 830 is provided with a slider spring groove 8330, and the slider spring 860 is arranged in the slider spring groove 8330. The slider spring 860 surrounds the connecting rod slider 830 to provide a radial contraction force for the connecting rod slider 830.

[0065] The main air path 110 , the shaft cylinder air path 510 , and the sleeve cylinder air path 610 are connected to the piston chamber 730 .

[0066] The modular sleeve wire drawing machine head also includes a sheet expansion spring 90, which is disposed in sheet expansion spring slots 410 at both ends of the thermal break bridge sheet expansion 40. The sheet expansion spring 90 surrounds the sheet expansion spring slots 410 of the thermal break bridge sheet expansion 40 to provide radial contraction force for the thermal break bridge sheet expansion 40.

[0067] The modular structure of the sleeve wire drawing machine head also includes a head front cover 100 and a head rear cover 200; the head front cover 100 is fixedly assembled on the upper wire ring 20, and the head rear cover 200 is fixedly assembled on the draw rod seat 30.

[0068] Among them: the number of connecting rod sliders 830, connecting rods 840, and slider ring top springs 850 can be flexibly configured according to actual needs. In this embodiment, the number of connecting rod sliders 830, connecting rods 840, and slider ring top springs 850 is 12. Correspondingly, the number of slope slider grooves 8210 on the slope slider ring 820 is also 12.

[0069] Implementation mechanism of the expansion and retraction mechanism:

[0070] When the compressed air is turned on, the piston ring 810 pushes the ramp slider ring 820 to move toward the front end, compressing the slider ring top spring 850; at the same time, after the connecting rod slider 830 loses the supporting effect of the ramp slider ring 820, it slides down along the ramp slider groove 8210 under the action of the slider tension spring 860, and after losing the supporting effect of the connecting rod slider 830, the broken bridge expansion plate 80 contracts radially under the action of the expansion plate tension spring 90.

[0071] When the compressed air is disconnected, the ramp slider ring 820 pushes the piston ring 810 into the piston ring cavity 730 under the action of the slider ring top spring 850; at the same time, the connecting rod slider 830 slides up along the ramp slider groove 8210, and the broken bridge expansion piece 80 is expanded under the support of the connecting rod slider 830.

[0072] When the connecting rod slider 830 slides up or down along the slope slider groove 8210, the connecting rod 840 and the slope slider groove 8210 limit the up and down sliding range of the connecting rod slider 830 within a fixed range, so that when subjected to an upward sliding driving force or a downward sliding driving force, the connecting rod slider 830 can respond quickly and effectively, reduce invalid upward sliding or invalid downward sliding stroke, reduce system response time, and improve control accuracy and efficiency.

[0073] At the same time, when the expansion piece is lifted, the connecting rod 840 can also provide a normal limiting force (parallel to the direction of the main axis 10 of the machine head) on the connecting rod slider 830, preventing the connecting rod slider 830 from displacing on the expansion piece in a direction parallel to the main axis 10 when pushed by the ramp slider groove 8210, further ensuring the efficiency of the expansion piece extension. In addition, during the process of lifting the expansion piece, the connecting rod 840 can also provide radial support force to the connecting rod slider 830, and a portion of the reaction force from the expansion piece is borne by the connecting rod 840, thereby balancing the force on the ramp slider ring 820 and improving the stability of the expansion piece extension action.

[0074] On a wire drawing machine with a multi-branch, ultra-long die head, as the length of the sheet increases, the middle part of the sheet will inevitably bend (soft waist). The cone sleeve set in the middle of the sheet on the existing wire drawing machine cannot solve the soft waist problem due to insufficient thrust, thus limiting the length development of the die head. This application uses a new type of independently developed sheet expansion and retraction mechanism to cooperate with the operation of the long die head. It not only solves the soft waist problem that is prone to occur in longer sheets, but also reduces the system response time, improves control accuracy and control efficiency, and increases the stability of the sheet expansion and retraction movement. At the same time, since a plurality of sheet expansion broken bridge grooves 420 are provided on the broken bridge type sheet expansion 40, the bending deformation points of the longer sheet during operation will be concentrated in the sheet expansion broken bridge groove 420, and a sheet expansion retraction mechanism 80 is provided corresponding to each sheet expansion broken bridge groove 420. Therefore, even if the sheet is ultra-long, lightweight and easily deformed, the soft waist phenomenon will not occur during operation. Therefore, the modular structure of the socket-type wire drawing machine head disclosed in this application also allows for the lightweight development of the expanding sheet, thereby reducing the difficulty of processing and installing the expanding sheet and the centrifugal force during operation, reducing the power consumption of the wire drawing machine, and improving the control accuracy of the expanding sheet extension.

[0075] In a modified embodiment of the present application, the modular structure of the sleeve-type wire drawing machine head also includes a front bearing and bearing seat 3, an oil spray ring 4, a motor and motor seat 5, a rear bearing and bearing seat 6, a dustproof deep palace 7, and a rotary joint 8. The head spindle 10 is transmission-connected to the motor and motor seat 5, the front bearing and bearing seat 3, the oil spray ring 4 are arranged at the front end of the motor and motor seat 5, the rear bearing and bearing seat 6, the dustproof deep palace 7 are arranged at the rear end of the motor and motor seat 5, and the rotary joint 8 is fixedly assembled at the rear end end of the head spindle 10; an oil mist channel 31 is provided in the front bearing and bearing seat 3, and the oil mist channel 31 is connected to the oil spray ring 4. The modular structure of the sleeve-type wire drawing machine head also includes a barrel changing mechanism 9, which includes a barrel changing turntable 91 and a barrel changing bearing 92. The barrel changing turntable 91 is used to drive the head to complete the barrel changing and flipping, and the barrel changing bearing 92 is used to support the rotation of the barrel changing turntable 91.

[0076] The technical solutions and technical effects of the present application are described in detail above in combination with the drawings and specific embodiments of the specification. It should be noted that technicians in this field can also develop other embodiments on this basis; any simple deformation and equivalent substitution that does not deviate from the innovative concept of the present application are covered by the present application and fall within the scope of protection of this patent.
