Description

Technical Field

[0001] This application belongs to the technical field of glass fiber production, and specifically relates to a head reciprocating wire drawing machine for both thick and thin yarns with a half-axis drive type. Background Art

[0002] A glass fiber wire drawing machine is a special equipment for the production of glass fiber yarn drawing. There is a shuttle forced wire arranging method, called a direct yarn wire drawing machine, and the wound yarn cake is cylindrical. There is also a type that uses a steel wire wire arranging device, called a cheese wire drawing machine. Since the yarn is passively arranged by the steel wire wire arranging device, the wound yarn cake is in the shape of a spindle, and the weight cannot be increased. It is necessary to reciprocate through the wire arranging assembly to increase the width, resulting in a larger spindle shape, more serious layer difference, and easier deformation and collapse, which affects the subsequent processes, cannot achieve large package weight increase, and also affects the quality improvement of products. With the continuous development of glass fiber towards high-end products, the use of a head reciprocating process in wire drawing can solve the above problems. Implementing the reciprocating linear motion or telescopic motion of the head can not only make the winding more uniform, but also improve the production capacity of the wire drawing machine. However, adding a head telescopic function in addition to the head rotation and flipping functions will undoubtedly increase the complexity of the equipment and its control system. At the same time, due to the greater flexibility of the head, it will also affect the stability of the head operation. Although there have been head reciprocating wire drawing machines on the market, the equipment is large and the structure is complex. The head assembly is heavy and has a large inertia, which affects the formation of reciprocating cheese. It cannot be used for fine yarn and more sub-drawing of an ultra-long head, and the pusher cylinder is also restricted by the length of the frame itself and cannot be extended, making it difficult to achieve a more stable and effective automatic pusher cylinder function.

[0003] The head reciprocating wire drawing machine for both thick and thin yarns with a half-axis drive type and its control method claimed in this application are one of the feasible solutions to realize the full-automatic threading, bobbin changing, yarn breaking, and pusher cylinder of glass fiber wire drawing and have the head reciprocating motion function. The technical documents related to this application include:

[0033] In the reciprocating winding step, the head reciprocating mechanism is started. Under the action of the reciprocating driving device, the pushing disk drives the current winding head (the first head or the second head) to make a linear reciprocating motion on its corresponding spline pair support seat (the first spline pair support seat or the second spline pair support seat) through the cooperation between the driving clamp and the push head (the first push head or the second push head) of the current winding head, so as to wind the glass fiber yarn on the current winding head;

[0035] In the bobbin changing step, after the current head winds the bobbin full, the head reciprocating mechanism first drives the push head (the first push head or the second push head) of the full bobbin head to the guide groove; then the bobbin changing mechanism is started to drive the first head and the second head to flip so as to flip the empty bobbin head to the winding station of the wire drawing machine, and the positions of the first head and the second head are flipped; then the head reciprocating mechanism is started to drive the current winding head (the first head or the second head) to make a linear reciprocating motion to continue wire drawing and winding;

[0036] In the bobbin unloading step, the auxiliary pushing device pushes the full bobbin head (the first head or the second head) forward to send the yarn; the yarn unloading manipulator comes to the lower side of the yarn bobbin and moves upward to hold the yarn bobbin; the auxiliary pushing device drives the head to return to the initial position, and the yarn bobbin is carried on the yarn unloading manipulator.

At the same time, by configuring a spline pair support mechanism for the first head and the second head, the stability of the head during telescopic and rotational motions can be improved; by configuring a guiding mechanism for the bobbin changing mechanism, the smoothness of the bobbin changing and flipping of the wire drawing machine can be enhanced.

[0039] 2. The head reciprocating wire drawing machine for both thick and thin yarns with half - shaft drive provided by this application and its control method can also flexibly adapt to the actual production requirements of thick yarns and thin yarns by configuring different head structures for the wire drawing machine, which is beneficial to improving the adaptability of the wire drawing machine.

[0080] Term explanation: The existing wire drawing machine generally includes a frame, a bobbin changing turntable arranged on the frame, and two machine heads arranged on the bobbin changing turntable (please refer to Chinese Patent: Slow - drawing automatic threading - on - line non - cutting yarn transition yarn guiding mechanism / CN211141896U)Figure 1 ). When winding the yarn, first fix the paper tube for winding the glass fiber on the machine head, then connect the glass fiber to the paper tube, and rotate the machine head to wind the glass fiber around the paper tube to form a yarn ball or a silk cake. When the paper tube being wound is full of glass fiber (full tube), rotate the tube-changing turntable to replace the unwound paper tube (empty tube) to the winding position to continue winding. The yarn ball or silk cake after being full tube is taken off by a manipulator or manually and enters the next process.

[0081] In this application, the process of connecting the glass fiber to the empty paper tube at the beginning is called "threading the head", and the process of rotating the tube-changing turntable to rotate the working positions of the empty tube machine head and the full tube machine head is called "changing the head" or "changing the tube" in this application. The above-mentioned winding position refers to the winding station of the wire drawing machine, and the position where the full tube machine head is turned over is called the standby station in this application. Each machine head repeatedly turns and rotates between the winding station and the standby station.

[0082] In this application, the two ordinal numbers "first" and "second" are used to distinguish the components, assemblies or mechanisms with the same structure and function, and do not represent the sequence or superiority of the limited components, assemblies or mechanisms in terms of structure, function or importance. For example, the first machine head, the second machine head, the first reciprocating support mechanism of the machine head, the second reciprocating support mechanism of the machine head, the first pusher head, the second pusher head, etc.

[0083] Direction description: The reciprocating linear motion or telescopic motion of the machine head in this application refers to the linear reciprocating motion of the first machine head or the second machine head on its axis. The turning of the machine head or the turning of the tube-changing refers to the rotational motion of the tube-changing turntable driving the first machine head and the second machine head. The end of the machine head connected to the frame is called the rear end, and the end of the machine head away from the frame is called the front end.

[0098] The first transmission half shaft 210 and the first spline shaft 3120 are of an integrally formed structure; alternatively, a fixed connection is established between the first transmission half shaft 210 and the first spline shaft 3120 through the first transmission half shaft flange 2100. Similarly, the second transmission half shaft and the second spline shaft are of an integrally formed structure; alternatively, a fixed connection is established between the second transmission half shaft and the second spline shaft through the second transmission half shaft flange.

[0099] When the first transmission half shaft 210 or the second transmission half shaft makes a rotational movement, the first spline shaft 3120 can rotate together with the first transmission half shaft 210, and the second spline shaft can rotate together with the second transmission half shaft; when the first transmission half shaft 210 or the second transmission half shaft makes a linear reciprocating movement, the first spline shaft 3120 can make a linear reciprocating movement together with the first transmission half shaft 210, and the second spline shaft can make a linear reciprocating movement together with the second transmission half shaft.

[0100] The first head 20 further includes a first transmission half shaft motor 220 and a first push motor seat 230. The first transmission half shaft motor 220 is drivingly connected to the first transmission half shaft 210. The first push motor seat 230 is fixedly connected to the first transmission half shaft motor 220. The first transmission half shaft 210, the first transmission half shaft motor 220, and the first push motor seat 230 can make a linear reciprocating movement together, and the first transmission half shaft motor 220 can also drive the first transmission half shaft 210 to make a rotational movement.

[0101] The second head 50 further includes a second transmission half shaft motor and a second push motor seat. The second transmission half shaft motor is drivingly connected to the second transmission half shaft. The second push motor seat is fixedly connected to the second transmission half shaft motor. The second transmission half shaft, the second transmission half shaft motor, and the second push motor seat can make a linear reciprocating movement together, and the second transmission half shaft motor can also drive the second transmission half shaft to make a rotational movement.

[0102] A first push head 2310 is arranged on the first push motor seat 230 , and a second push head is arranged on the second push motor seat; the first push head 2310 and the second push head are used to cooperate with the machine head reciprocating mechanism 40 to realize linear reciprocating drive of the first machine head 20 or the second machine head 50 .

[0103] As mentioned above, the first transmission half shaft 210 of the first machine head 20 is assembled in the first rolling spline pair 310 and fixedly connected to the first spline shaft 3120, and the second transmission half shaft of the second machine head 50 is assembled in the second rolling spline pair and fixedly connected to the second spline shaft. Thus, the first machine head 20 and the second machine head 50 can complete the tube change and flipping under the drive of the tube change mechanism 70.

[0104] The machine head reciprocating mechanism 40 includes a reciprocating drive device 410 and a push plate 420. The reciprocating drive device 410 is disposed on the frame 10, and the push plate 420 is connected to the reciprocating drive device 410. The push plate 420 can perform linear reciprocating motion under the action of the reciprocating drive device 410. The push plate 420 is provided with a driving clamp 4210 for cooperating with the first push head 2310 and the second push head. The driving clamp 4210 is used to cooperate with the first push head 2310 or the second push head to realize linear reciprocating drive of the first machine head 20 or the second machine head 50.

[0105] The driving jaw 4210 is an open structure, which can allow the first pusher head 2310 or the second pusher head to perform a tube-changing and flipping action. Preferably, the driving jaw 4210 is a U-shaped driving jaw.

[0106] When the two heads are turned over by the barrel changing mechanism 70, the first pusher head 2310 or the second pusher head can enter the driving jaw 4210, and then the first head 20 or the second head 50 is driven to perform linear reciprocating motion together by the reciprocating drive device 410. When the winding head is full, the current pusher head (the first pusher head 2310 or the second pusher head) can perform rotational motion under the action of the barrel changing mechanism 70 to rotate the other pusher head (the second pusher head or the first pusher head 2310) into the driving jaw 4210.

[0107] The machine head reciprocating mechanism 40 can use a variety of reciprocating drive devices 410 to drive the push plate 420. For example, the reciprocating drive device 410 can include a reciprocating motor 4110, a reciprocating push slide 4120 and a reciprocating transmission lead screw; the reciprocating motor 4110 is assembled on the frame 10 and is connected to the reciprocating transmission lead screw, the reciprocating push slide 4120 is assembled on the reciprocating transmission lead screw through threaded transmission, and the push plate 420 is connected to the reciprocating push slide 4120. When the reciprocating motor 4110 rotates forward or reversely, it can drive the push plate 420 to perform linear reciprocating motion.

[0108] The assembly position of the head reciprocating mechanism 40 should be able to meet the requirement of linearly reciprocatingly driving the head at the winding station of the wire drawing machine. No matter which head is at the winding station of the wire drawing machine, it can achieve the linear reciprocating drive of the current head through the movable drive connection between the drive chuck 4210 and the current pusher head (the second pusher head or the first pusher head 2310).

[0109] The guiding mechanism 80 includes an open annular guiding ring 810. The guiding ring 810 includes a front guiding plate 8130 and a rear guiding plate 8140. The front and rear guiding plates are connected into one body through a fixed sleeve 8150 and fixed to the frame 10. A guiding groove 8110 is defined between the front and rear guiding plates. A guiding opening 8120 is provided at the position corresponding to the drive chuck 4210 on the guiding ring 810. The bobbin changing main shaft 730 passes through the inner ring hollow part of the guiding ring 810.

[0110] When the two heads change bobbins and flip, the head reciprocating mechanism 40 first drives the pusher head of the current head (the first pusher head 2310 or the second pusher head) into the guiding groove 8110. At this time, the pusher heads of both heads are in the guiding groove 8110, and then the bobbin changing mechanism 70 starts to flip to perform the bobbin changing operation. After the bobbin changing, the pusher head of the empty bobbin head is in the drive chuck 4210. The empty bobbin head starts to rotate, and at the same time, the head reciprocating mechanism 40 drives the empty bobbin head to perform a linear reciprocating motion to continue wire drawing and winding.

[0111] The control system can be an industrial control micro host or other industrial control modules, components, assemblies or devices. The first transmission half shaft motor 220 of the first head 20, the reciprocating drive device 410 of the head reciprocating mechanism 40, the second transmission half shaft motor of the second head 50, and the bobbin changing motor 720 of the bobbin changing mechanism 70 are all electrically connected to the control system.

[0112] The control method of the head reciprocating wire drawing machine for both thick and thin yarns with half shaft transmission disclosed in this application is as follows:

[0113] In the above step, the glass fiber yarn is slowly pulled and towed by the slow pulling and towing mechanism to the current winding head. The glass fiber yarn is captured by the thread guiding hook and wound on the thread guiding ring. The glass fiber yarn is pushed by the yarn pushing rod to the winding part for wire drawing and winding.

[0114] In the reciprocating winding step, the head reciprocating mechanism 40 is started. Under the action of the reciprocating drive device 410, the pushing disk 420 drives the current winding head to perform a linear reciprocating motion on its corresponding spline pair support seat through the cooperation between the drive chuck 4210 and the pusher head of the current winding head to wind the glass fiber yarn on the current winding head.

[0115] In the yarn breaking step, the yarn breaking mechanism cooperates with the yarn breaking groove on the thread guiding ring to cut off the connection between the yarn ball or yarn cake and the transition yarn.

[0116] Changing bobbin steps: after the current headstock is full of wound yarn, the headstock reciprocating mechanism 40 first drives the push head of the full bobbin headstock to the guide groove 8110; then the bobbin changing mechanism 70 is started, driving the first headstock 20 and the second headstock 50 to rotate to turn the empty bobbin headstock to the winding station of the wire drawing machine. When the headstock is turned, the first push head 2310 and the second push head rotate in the guide groove 8110 at the same time; then the headstock reciprocating mechanism 40 is started, driving the current winding headstock to do a linear reciprocating motion to continue wire drawing and winding.

[0117] In a changed embodiment of the present application, a first pushing slider 2311 and a first pushing pin shaft 2312 are further provided on the first push head 2310. A second pushing slider and a second pushing pin shaft are further provided on the second push head. Through the sliding fit of the first pushing slider 2311, the second pushing slider and the inner wall of the guide ring 810, the resistance during the headstock turning can be reduced, and the smoothness of the headstock turning motion can be increased.

[0118] Different headstock structures can be configured for the first headstock and the second headstock in the present application to meet the actual production needs of different glass fiber yarns.

[0119] When the glass fiber filaments for wire drawing and winding are fine yarns, the first headstock 10 can be configured to further include a first aluminum rotating cylinder 240, a first sealing ring sleeve 250, a first wire feeding ring 260, a front end cover, and a rear end cover. A first rotating cylinder main shaft hole 2410 is provided on the first aluminum rotating cylinder 240, and a first sleeve groove 2420 is provided at one end of the first rotating cylinder main shaft hole 2410; a first sleeve assembly main shaft hole 2510 and a first support seat accommodating cavity 2520 are provided on the first sealing ring sleeve 250; the first wire feeding ring 260 is fixed to the front end of the first aluminum rotating cylinder 240, and the first spline shaft 3120 and the first transmission half shaft 210 are accommodated in the first rotating cylinder main shaft hole 2410 and the first sleeve assembly main shaft hole 2510, and the first sealing ring sleeve 250 is arranged in the first sleeve groove 2420; the first transmission half shaft 210, the first spline shaft 3120, the first aluminum rotating cylinder 240, the first sealing ring sleeve 250, and the first wire feeding ring 260 are fixedly connected; the first spline pair support seat 320 can be slidably accommodated in the first support seat accommodating cavity 2520.

[0120] When the headstock changes the bobbin and turns over, the first transmission half shaft 210, the first transmission half shaft motor 220, the first pushing motor seat 230, the first aluminum rotating cylinder 240, the first sealing ring sleeve 250, and the first wire feeding ring 260 can rotate synchronously; when the wire drawing headstock does a linear reciprocating motion, the first transmission half shaft 210, the first transmission half shaft motor 220, the first pushing motor seat 230, the first aluminum rotating cylinder 240, the first sealing ring sleeve 250, and the first wire feeding ring 260 can do a linear reciprocating motion synchronously.

[0121] When the first head 20 makes a linear reciprocating motion, a corresponding linear motion cooperation will occur between the first seal ring sleeve 250 and the first spline pair support seat 320. While increasing the motion stability, the first seal ring sleeve 250 can also reduce the mutual wear between the first spline pair support seat 320 and the first aluminum rotating cylinder 240 and facilitate replacement. At the same time, the first seal ring sleeve 250 can also prevent external debris such as oil, chips, and yarn from entering the interior of the first head 20 when the head makes a reciprocating motion.

[0122] Corresponding to the first head 20, the second head 50 also includes the same head structure and connection and cooperation relationships, which will not be elaborated here.

[0123] When the fiberglass filament for wire drawing and winding is roving, it is also necessary to configure a flapper and a flapper telescopic mechanism for the first head 20 and the second head 50 to meet the production requirements of roving. Taking the first head 20 as an example, the first head 20 further includes a first flapper 270 and a first end telescopic mechanism 280.

[0124] Please refer to Figure 5 , a first clamping position 2430 is also provided on the first aluminum rotating cylinder 240, and the connecting part of the first flapper 270 has a mechanism that matches the first clamping position 2430. When the first flapper 270 is movably clamped in the first clamping position 2430, this movable clamping connection structure can prevent the flapper 270 from falling off radially from the first aluminum rotating cylinder 240. For the movable clamping connection, please refer to Chinese Patent: A Head Flapper Intermediate Cone Sleeve Support Device (Publication No. CN213803526U).

[0125] The first end telescopic mechanism 280 includes a first end cone sleeve 2810 and a first end cone sleeve spring 2820.

[0126] A first end assembly position 2440 and a first air hole 2470 are also provided on the first aluminum rotating cylinder 240.

[0127] The first end assembly position 2440 can be respectively arranged at both ends of the first aluminum rotating cylinder 240, and the number of the first end cone sleeves 2810 can be two, which are respectively arranged in the first end assembly positions 2440 at both ends of the first aluminum rotating cylinder 240.

[0128] The first end cone sleeve 2810 and the first end cone sleeve spring 2820 are both arranged within the first end assembly position 2440. A first mating cone surface 2710 that mates with the first end cone sleeve 2810 is provided at the corresponding position of the first expanding piece 270. The first air hole 2470 communicates with the first end assembly position 2440. After the compressed air enters the first end assembly position 2440 through the first air hole 2470, it can drive the first end cone sleeve 2810 to loosen the first mating cone surface 2710 so that the expanding piece contracts, and at the same time, the first end cone sleeve 2810 compresses the first end cone sleeve spring 2820. After cutting off the compressed air, the first end cone sleeve spring 2820 can drive the first end cone sleeve 2810 to tightly press against the first mating cone surface 2710 so that the expanding piece expands.

[0129] In a variant embodiment of the present application, the first end telescoping mechanism 280 further includes a first expanding piece tension spring. The first expanding piece tension spring is wound around a plurality of first expanding pieces 270, or a first expanding piece tension spring groove is provided on the first expanding piece 270, and the first expanding piece tension spring is arranged in the first expanding piece tension spring groove for providing a radial contraction force for the first expanding piece 270.

[0130] For the interaction relationship among the first end cone sleeve 2810, the first end cone sleeve spring 2820, the first air hole 2470, and the first mating cone surface 2710, please refer to the Chinese patent: A Head Expanding Piece Intermediate Cone Sleeve Support Device with the publication number CN213803526U, which will not be elaborated here.

[0131] For a general head spindle, setting expanding piece telescoping mechanisms at both ends of the head spindle can already achieve efficient automatic telescoping switching of the expanding pieces. However, for the head reciprocating wire drawing machine involved in the present application, since the head spindle is relatively long, only setting expanding piece telescoping mechanisms at both ends will affect the telescoping efficiency and control accuracy of the expanding pieces. Therefore, the present application adds a middle expanding piece telescoping mechanism at the middle part of the aluminum rotating cylinder. Correspondingly, the first head and the second head further include a first middle telescoping mechanism 290 and a second middle telescoping mechanism respectively.

[0132] Please refer to Figure 6 and Figure 7 , a first middle assembly position 2450 and a first pull rod hole 2460 are further provided on the first aluminum rotating cylinder 240.

[0133] The first middle telescopic mechanism 290 includes a first pull rod 2910, a first ramp slider 2920, a first slider movable seat 2930, a first slider connecting rod 2940, a first connecting rod seat 2950, and a first movable seat spring 2960. The first ramp slider 2920, the first slider movable seat 2930, the first slider connecting rod 2940, the first connecting rod seat 2950, and the first movable seat spring 2960 are all arranged within the first middle assembly position 2450; the first pull rod 2910 is arranged within the first pull rod hole 2460 and is respectively connected to the first end cone sleeve 2810 and the first slider movable seat 2930 at both ends.

[0134] Among them: The first connecting rod seat 2950 is fixedly assembled within the first middle assembly position 2450, and both ends of the first slider connecting rod 2940 are respectively movably connected to the first connecting rod seat 2950 and the first ramp slider 2920.

[0135] A number of first movable seat driving inclined slots 2931 are provided on the first slider movable seat 2930, and the first ramp slider 2920 is slidably assembled within the first movable seat driving inclined slots 2931. The first ramp slider 2920 produces a sliding fit with the ramp groove bottom of the first movable seat driving inclined slots 2931 through its first mating ramp 2921.

[0136] When the first ramp slider 2920 is jacked up or released, the first slider connecting rod 2940 and the first movable seat driving inclined slots 2931 can limit the up and down sliding range of the first ramp slider 2920 within a fixed range, so that when subjected to an upward sliding driving force or a downward sliding driving force, the first ramp slider 2920 can quickly make an effective response, reduce the ineffective upward sliding or ineffective downward sliding stroke, shorten the system response time, and improve the expansion sheet telescopic efficiency and control accuracy.

[0137] At the same time, when jacking up the expansion sheet, the first ramp slider 2920 can also provide a normal limiting force (parallel to the direction of the first machine head 20) to the first ramp slider 2920, preventing the first ramp slider 2920 from generating displacement on the expansion sheet along the direction parallel to the first machine head 20 when being pushed by the first movable seat driving inclined slots 2931, and further ensuring the efficiency of the expansion sheet extension. And during the process of jacking up the expansion sheet, the first slider connecting rod 2940 can also provide a radial supporting force to the first ramp slider 2920, and a part of the reaction force from the expansion sheet is borne by the first slider connecting rod 2940, so as to balance the force on the first slider movable seat 2930 and improve the stability of the expansion sheet extension action.

[0138] The movable connection relationship among the first slider link 2940, the first link seat 2950, and the first ramp slider 2920 is as follows: The first slider link 2940 includes a first link portion 2941 and first spherical link heads 2942 provided at both ends of the first link portion 2941. The first link seat 2950 is provided with a first link seat rod head accommodation position 2951, and a first link seat rod head movable opening 2952 is formed in the first link seat rod head accommodation position 2951. The first ramp slider 2920 is provided with a first slider rod head accommodation position 2922, and a first slider rod head movable opening 2923 is formed in the first slider rod head accommodation position 2922. The first spherical link heads 2942 at both ends of the first link portion 2941 are respectively movably embedded in the first link seat rod head accommodation position 2951 and the first slider rod head accommodation position 2922.

[0139] When the first end cone sleeve 2810 releases the first mating cone surface 2710 under the action of compressed air, the first end cone sleeve 2810 can drive the first slider movable seat 2930 to perform synchronous movement through the first pull rod 2910, so that the first slider movable seat 2930 releases the first ramp slider 2920, and thus the first expanding piece 270 automatically contracts; after the compressed air is cut off, the first end cone sleeve 2810 presses against the first mating cone surface 2710, and at the same time drives the first slider movable seat 2930 to press against the first ramp slider 2920 through the first pull rod 2910, so that the first ramp slider 2920 presses against the first expanding piece 270, and the first expanding piece 270 automatically expands.

[0140] Through the cooperation of the first end telescopic mechanism 280 at both ends and the first middle telescopic mechanism 290 in the middle, the automatic control of the expansion and contraction switching of the first expanding piece 270 can be realized by controlling the compressed air. Thus, the head reciprocating wire drawing machine for both thick and fine yarns with a half-axis type transmission disclosed in this application can be applicable to the wire drawing production of glass fiber rovings.

[0141] In a variant embodiment of the present application, the first middle telescopic mechanism 290 further includes a first ramp slider tension spring. A first slider tension spring groove is provided on the first ramp slider 2920. The first ramp slider tension spring is arranged in the first slider tension spring groove and surrounds a plurality of first ramp sliders 2920, and is used to provide a radial contraction force for the first ramp slider 2920.

[0142] The structure, connection, and function of the second head 50 and the first head 20 are the same as those of the first head 20, and will not be elaborated here.

[0143] In a variant embodiment of the present application, a first oil circuit is further provided on the first machine head 20. The first oil circuit is used to lubricate the first rolling spline pair 310 and the first spline pair support seat 320. In another variant embodiment, the first machine head 20 may further include a first transmission half shaft flange 2100, a first rotating bearing seat 2200, and a first bearing sleeve shaft 2300. The first transmission half shaft 210 is disposed within the first spline shaft 3120 and is provided with a first transmission half shaft flange 2100, a first rotating bearing seat 2200, and a first bearing sleeve shaft 2300 at its front end. The first transmission half shaft 210, the first spline shaft 3120, the first transmission half shaft flange 2100, the first rotating bearing seat 2200, the first aluminum rotating cylinder 240, and the first wire threading ring 260 are fixedly connected. The first oil circuit communicates with the first bearing sleeve shaft 2300. By configuring the first bearing sleeve shaft 2300 and the first oil circuit on the first machine head 20, lubrication of the first rolling spline pair 310, the first spline pair support seat 320, and the interior of the front end of the first machine head 20 can be achieved. The structure, connection, and functions of the second machine head 50 are the same as those of the first machine head 20 and will not be elaborated herein.

[0144] To cooperate with the yarn discharging push cylinder of a head reciprocating wire drawing machine for both thick and thin yarns with half shaft type transmission, in a variant embodiment of the present application, an automatic push cylinder mechanism capable of adapting to the head reciprocating wire drawing machine is also involved.

[0145] Please refer to Figure 8 and Figure 9 , the head reciprocating wire drawing machine further includes a first push cylinder mechanism and a second push cylinder mechanism 90. The first push cylinder mechanism and the second push cylinder mechanism 90 are respectively used to complete the push cylinder work of the first machine head 20 and the second machine head 50.

[0146] Taking the second push cylinder mechanism 90 as an example, the push cylinder mechanism will be described below.

[0147] The second push cylinder mechanism 90 includes a second push cylinder 910 and a second push plate 920; a second machine head fitting portion 9210 is provided on the second push plate 920.

[0148] The second push cylinder 910 is fixedly provided on the bobbin changing turntable 710, and the second push plate 920 is fixedly connected to the piston shaft of the second push cylinder 910. The second machine head fitting portion 9210 has a structure and dimensions that fit the second machine head 50 and is attached to the second machine head 50.

[0149] The second barrel pushing plate 920 can push the bobbin on the second machine head 50 under the action of the second barrel pushing cylinder 910. Since the second barrel pushing cylinder 910 is arranged on the barrel changing turntable 710, the second barrel pushing plate 920 can push the bobbin off the machine head even if the machine head is very long. Compared with the existing barrel pushing scheme in which the barrel pushing mechanism is arranged at other parts other than the barrel changing turntable 710, it has the technical characteristics of high barrel pushing efficiency and long barrel pushing stroke.

[0150] The first push-cylinder mechanism has the same structure and connection as the second push-cylinder mechanism 90 .

[0151] The assembly position of the first push-barrel mechanism 90 and the second push-bar mechanism is preferably set in the idle position of the isolation plate seat 100 or the yarn separation plate on the wire drawing machine. For the existing yarn separation plate, please refer to the Chinese patent: Slow-pull automatic head-up online cut-free yarn transition yarn introduction mechanism (publication number: CN211141896U). The existing isolation plate seat 100 generally includes an isolation plate seat body 1010 and a first shielding part 1020 and a second shielding part 1030 arranged at both ends of the isolation plate seat body 1010. An idle space is formed between the first shielding part 1020 and the second shielding part 1030 and the corresponding machine head; the first push-bar mechanism 90 and the second push-bar mechanism are respectively arranged in the idle areas of the first shielding part 1020 and the second shielding part 1030, which can improve the compactness of the wire drawing machine and reduce the volume of the equipment.

[0152] See also Figure 10 and Figure 11 In a modified embodiment of the present application, the semi-axial transmission coarse and fine yarn dual-purpose machine head reciprocating wire drawing machine also includes an auxiliary ejection device 200, and the auxiliary ejection device 200 includes an auxiliary ejection seat 2010 and an auxiliary ejection mechanism 2020. The auxiliary ejection seat 2010 is provided with an ejection drive port 2011, and the ejection drive port 2011 is used to receive the driving force from the auxiliary ejection mechanism 2020 to drive the auxiliary ejection seat 2010 to be ejected toward the front end of the machine head. The auxiliary ejection mechanism 2020 includes an auxiliary ejection motor 2021, an auxiliary ejection slide 2022, and an auxiliary ejection screw (not shown in the figure). The auxiliary ejection motor 2021 is assembled on the frame 10 and is transmission-connected to the auxiliary ejection screw, the auxiliary ejection slide 2022 is assembled on the auxiliary ejection screw through a threaded transmission connection, and the auxiliary push seat 2010 is fixedly connected to the auxiliary ejection slide 2022. When the auxiliary ejection motor 2021 rotates forward or reversely, it can drive the auxiliary ejection seat 2010 to do linear reciprocating motion.

[0153] The pushing driving port 2011 realizes the pushing of the first head 20 or the second head 50 through the cooperation between the first pushing head 2310 on the first head 20 or the second pushing head on the second head 50. The structure of the pushing driving port 2011 and the driving cooperation relationship with the pushing head are the same as those of the driving clamping port 4210 in the foregoing head reciprocating mechanism 40 and the driving cooperation relationship with the pushing head, and will not be elaborated herein.

[0154] Similar to the foregoing guiding opening 8120, an auxiliary guiding opening 8160 is provided at a position corresponding to the movement of the pushing driving port 2011 on the guiding mechanism 80. When the auxiliary pushing device 200 drives the first head 20 or the second head 50 to return, the auxiliary pushing seat 2010 drives the first pushing head 2310 or the second pushing head to return to the guiding groove 8110 through the auxiliary guiding opening 8160.

[0155] In a variant embodiment of the present application, the auxiliary pushing mechanism 2020 can also be a pneumatic or hydraulic component such as a cylinder or an oil cylinder.

[0156] When producing roving, the auxiliary pushing device 200 is an auxiliary pushing mechanism of the bobbin unloading manipulator. The bobbin unloading manipulator can hold the outer circle of the cake of silk and cooperate with the auxiliary pushing device 200 to automatically unload the yarn (take out the yarn ball). The steps of unloading the yarn can be as follows:

[0157] The head extends for yarn feeding, and the auxiliary pushing device 200 pushes the full bobbin head (the first head 20 or the second head 50) to extend forward for yarn feeding;

[0158] The manipulator holds the yarn, and the bobbin unloading manipulator comes to the lower side of the yarn ball and moves upward to hold the yarn ball;

[0159] The head retracts for yarn unloading, and the auxiliary pushing device 200 drives the head to return to the initial position (i.e., the standby station), and the yarn ball is carried on the bobbin unloading manipulator.

[0160] The foregoing actions of the head extending for yarn feeding and the manipulator coming to the lower side of the yarn ball can be carried out successively or simultaneously.

[0161] The complete control method of the semi-axle type transmission roving and spinning dual-purpose head reciprocating wire drawing machine with the auxiliary pushing device 200 is as follows:

[0162] In the above steps, the glass fiber yarn is pulled slowly by the traction mechanism to the current winding head, the glass fiber yarn is captured by the yarn guiding hook and wound on the yarn guiding ring, and the glass fiber yarn is pushed by the yarn pushing rod to the winding part for wire drawing and winding;

[0163] Reciprocating winding step: The head reciprocating mechanism is started. Under the action of the reciprocating driving device, the pushing disk drives the current winding head (the first head or the second head) to perform a linear reciprocating motion on its corresponding spline pair support seat (the first spline pair support seat or the second spline pair support seat) through the cooperation between the driving jaw and the pushing head (the first pushing head or the second pushing head) of the current winding head, and winds the fiberglass yarn on the current winding head.

[0164] Yarn breaking step: The yarn breaking mechanism cooperates with the yarn breaking groove on the wire feeding ring to cut off the connection between the yarn cake or yarn ball and the transition yarn.

[0165] Bobbin changing step: After the current head winds the bobbin full, the head reciprocating mechanism first drives the pushing head (the first pushing head or the second pushing head) of the full bobbin head to the guiding groove; then the bobbin changing head is started, driving the first head and the second head to turn over to turn the empty bobbin head to the winding station of the wire drawing machine, and the positions of the first head and the second head are reversed; then the head reciprocating mechanism is started, driving the current winding head (the first head or the second head) to perform a linear reciprocating motion to continue wire drawing and winding.

[0166] Bobbin unloading step: The auxiliary pushing device pushes the full bobbin head (the first head or the second head) forward to feed the yarn; the yarn unloading manipulator comes to the lower side of the yarn ball and moves upward to hold the yarn ball; the auxiliary pushing device drives the head after unloading the full bobbin back to the initial position (the pushing head of the head after unloading the full bobbin returns to the guiding circle), and the yarn ball is carried on the yarn unloading manipulator.

[0167] In terms of the control method, the main differences between this application and the prior art are mainly reflected in the reciprocating winding step, the bobbin changing step and the bobbin unloading step, which are briefly summarized as follows:

[0168] Reciprocating winding step: Under the action of the reciprocating driving device, the pushing disk drives the current winding head to perform a linear reciprocating motion on its corresponding spline pair support seat through the cooperation between the driving jaw and the pushing head of the current winding head.

[0169] Bobbin changing step: The head reciprocating mechanism first drives the pushing head of the full bobbin head to the guiding groove; then the bobbin changing mechanism is started, driving the two heads to turn over to turn the empty bobbin head to the winding station of the wire drawing machine; the head reciprocating mechanism is started, driving the empty bobbin head to perform a linear reciprocating motion to continue wire drawing and winding.

[0170] Bobbin unloading step: The auxiliary pushing device pushes the full bobbin head forward to feed the yarn; the yarn unloading manipulator comes to the lower side of the yarn ball and holds the yarn ball upward; the auxiliary pushing device drives the full bobbin head back to the initial position, and the yarn ball is carried on the yarn unloading manipulator.

[0171] In a variant embodiment of this application, the half-axis type transmission dual-purpose thick and thin yarn head reciprocating wire drawing machine also adopts a multi-segment combined expanding piece for the long head and its corresponding wire drawing machine head. Please refer toFigure 12 The multi - segment combined expanding piece includes several expanding piece monomers 2400. Concave - part sockets 2401 and convex - part plugs 2402 are respectively arranged at both ends of the expanding piece monomer 2400 in the middle. The multiple expanding piece monomers 2400 are extended through the plug - in fit between the concave - part sockets 2401 and the convex - part plugs 2402 to form a multi - segment combined expanding piece. For the two expanding piece monomers 2400 at both sides, only a concave - part socket 2401 or a convex - part plug 2402 can be configured at one end.

[0172] Nowadays, the glass fiber drawing is developing towards multi - strand drawing with a large spinneret. The head is longer and the expanding piece is also longer. Due to the influence of centrifugal force, the expanding piece can only be lightened. However, after the longer expanding piece is lightened, its rigidity and straightness will be affected. After hardening, it is more likely to bend and deform, resulting in inconsistent opening sizes, which affects the slipping of the plastic winding cylinder, or bulging, causing faults inside the silk cake and affecting the subsequent unwinding. There are also great difficulties in the processing of the expanding piece. If the multi - segment expanding piece connection design is adopted, the above problems will be changed. Through the concave - convex connection at the splicing end of the expanding piece, each expanding piece has both synchronous and self - adjusting functions, so that each plastic winding cylinder can receive an appropriate tension force.

[0173] The components or parts used in conjunction with the multi - segment combined expanding piece also include an aluminum rotating cylinder, a front end cover, a rear end cover, a wire - threading ring, etc. Similar to the aforementioned first head 20 and second head 50, the connection and fit between the expanding piece monomer 2400 and the aluminum rotating cylinder also adopt Figure 5 the movable clamping connection shown. The connection and assembly among the aluminum rotating cylinder, the front end cover, the rear end cover, the wire - threading ring, and the multi - segment combined expanding piece are similar to the aforementioned ones, and will not be elaborated here.

[0174] Different from the aforementioned end telescoping mechanism and middle telescoping mechanism, due to the adoption of a multi - segment combined structure, in this embodiment, another expanding piece telescoping mechanism can be used to realize the telescoping of the expanding piece: Spring holes 2403 are arranged at the middle parts of the aluminum rotating cylinder corresponding to each expanding piece monomer 2400, and expanding piece telescoping springs are arranged in the spring holes 2403. The expanding piece telescoping springs provide driving force for the expanding piece monomer 2400 to reduce the complexity of the head.

[0175] The technical solutions and technical effects of the present application have been elaborated in detail above in combination with the specification drawings and specific embodiments. It should be noted that those skilled in the art can also develop other embodiments on this basis; any simple deformation and equivalent replacement that do not depart from the innovative concept of the present application are covered by the present application and belong to the protection scope of this patent.
