Description

Technical Field

[0001] The present application belongs to the technical field of glass fiber production, and specifically relates to a semi-axially driven reciprocating drawing machine for both coarse and fine yarns and a control method thereof. Background Art

[0002] Glass fiber drawing machines are specialized equipment used for the production of glass fiber yarn. Some machines use a shuttle-driven forced yarn arrangement, known as direct yarn drawing machines, producing cylindrical yarn balls. Other machines utilize a wire guide, known as cake drawing machines. Because the yarn is passively displaced by the guide, the resulting yarn balls form a skein shape, which hinders weight. This necessitates a reciprocating wire guide assembly to increase width. This creates a larger skein shape, more severe layer differences, and a greater tendency for deformation and collapse, impacting subsequent processing steps. This prevents the production of large packages and reduces product quality. As glass fiber continues to evolve towards higher-end products, the use of a reciprocating die head process in drawing can address these issues. Implementing reciprocating linear or telescopic motion in the die head not only ensures more uniform winding but also increases the machine's production capacity. However, adding a telescopic die head function, in addition to its rotation and flipping capabilities, increases the complexity of the equipment and its control system. Furthermore, the increased flexibility of the die head can compromise its operational stability. Although there are reciprocating wire drawing machines on the market, the equipment is large and complex in structure. The head assembly is heavy and has large inertia, which affects the formation of reciprocating yarn cakes. It cannot be used for fine yarn and more branch drawing of ultra-long heads. The pusher is also limited by the length of the frame itself and cannot be extended, making it difficult to achieve a more stable and effective automatic pusher function.

[0003] The semi-axial drive reciprocating drawing machine for coarse and fine yarns and its control method, which are claimed in this application, are one of the feasible solutions for fully automatic fiberglass drawing, including the automatic feeding, bobbin changing, yarn cutting, and bobbin pushing, and also feature reciprocating motion of the machine head. Technical documents related to this application include:

[0004] A glass fiber die reciprocating large-volume heavy wire drawing machine has a publication number of CN115818952A, and involves a die turning mechanism and a die reciprocating mechanism.

[0005] The publication number of the slow-pull automatic head-up online cut-free yarn transition yarn feeding mechanism is CN211141896U, which involves a dual-head configuration scheme, a slow-pull traction mechanism, and a yarn separation plate structure.

[0006] A support device for the middle cone sleeve of a machine head expansion piece is disclosed with publication number CN213803526U, and involves an aluminum rotating cylinder, an expansion piece, a cone sleeve, a cone sleeve spring and their connection and matching relationship.

[0031] The control method of the semi-axial transmission head reciprocating wire drawing machine for coarse and fine yarns provided in this application is as follows:

[0032] In the winding step, the glass fiber yarn is pulled to the current winding head by the slow pulling mechanism, captured by the upper wire hook and wound on the upper wire ring, and pushed to the winding position by the yarn pushing rod for drawing and winding;

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

[0035] In the bobbin changing step, after the current head is wound with a full bobbin, the head reciprocating mechanism first drives the pusher head (the first pusher head or the second pusher head) of the full bobbin head to the guide groove; then the bobbin changing mechanism is started, driving the first head and the second head to flip over 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, driving the current winding head (the first head or the second head) to do a linear reciprocating motion to continue drawing and winding;

[0036] In the unloading step, the auxiliary ejection device pushes the full-bobbin machine head (the first head or the second head) forward to deliver the yarn; the yarn unloading robot comes to the lower side of the yarn ball and moves upward to support the yarn ball; the auxiliary ejection device drives the machine head back to the initial position, and the yarn ball is carried on the yarn unloading robot.

At the same time, by configuring the first head and the second head with a spline auxiliary support mechanism, the stability of the head during telescopic and rotational motion can be improved; by configuring the bobbin changing mechanism with a guide mechanism, the stability of the drawing machine during bobbin changing and flipping can be improved.

[0080] Explanation of terms: Existing wire drawing machines generally include a frame, a drum changing turntable arranged on the frame, and two heads arranged on the drum changing turntable (please refer to the Chinese patent: Slow-pull automatic head-up online cut-free yarn transition yarn feeding mechanism / CN211141896U Figure 1 During winding, the paper bobbin for winding is first fixed to the machine head. The glass fiber is then attached to the paper bobbin. The machine head rotates to wind the glass fiber onto the bobbin to form a yarn ball or yarn cake. When the paper bobbin being wound is filled with glass fiber (a full bobbin), the bobbin-changing turntable rotates to replace the unwound paper bobbin (an empty bobbin) to continue winding. The full bobbin yarn ball or yarn cake is then removed by a robot or manually for the next step.

[0081] The initial process of attaching the glass fiber filaments to the empty paper tube is referred to in this application as "head loading." The process of rotating the empty and full tube heads through the rotation of the tube changer is referred to as "head or tube changing." The aforementioned winding position refers to the wire drawing machine's winding station. The position of the full tube head after flipping is referred to in this application as the standby station. Each die head repeatedly flips and rotates between the winding station and the standby station.

[0082] In this application, the use of the ordinal numbers "first" and "second" to distinguish components, assemblies, or mechanisms with the same structure and function does not imply a precedence or order of importance of the components, assemblies, or mechanisms. For example, the first machine head, the second machine head, the first machine head reciprocating support mechanism, the second machine head reciprocating support mechanism, the first pusher head, the second pusher head, etc.

[0083] Directional Note: In this application, the term "reciprocating linear motion" or "extending and retracting motion" refers to the linear reciprocating motion of the first or second head about its axis. "Head flip" or "canister flip" refers to the rotational motion of the first and second heads driven by the canister changer. The end of the head connected to the frame is called the rear end, and the end away from the frame is called the front end.

[0084] Description of Axle-Shaft Drive: In this application, because the main shaft of the handpiece is partially located inside and partially outside the rolling spline pair, this drive is referred to as an axle-shaft drive.

[0100] The first machine head 20 further includes a first transmission axle motor 220 and a first propulsion motor base 230. The first transmission axle motor 220 is transmission-connected to the first transmission axle 210, and the first propulsion motor base 230 is fixedly connected to the first transmission axle motor 220. The first transmission axle 210, the first transmission axle motor 220, and the first propulsion motor base 230 can perform linear reciprocating motion together. The first transmission axle motor 220 can also drive the first transmission axle 210 to perform rotational motion.

[0101] The second machine head 50 also includes a second transmission half-shaft motor and a second propulsion motor mount. The second transmission half-shaft motor is transmission-connected to the second transmission half-shaft, and the second propulsion motor mount is fixedly connected to the second transmission half-shaft motor. The second transmission half-shaft, the second transmission half-shaft motor, and the second propulsion motor mount are capable of linear reciprocating motion together. The second transmission half-shaft motor can also drive the second transmission half-shaft to rotate.

[0102] A first push head 2310 is provided on the first push motor seat 230 , and a second push head is provided 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 previously described, the first transmission half-shaft 210 of the first machine head 20 is assembled within the first rolling spline pair 310 and fixedly connected to the first spline shaft 3120. The second transmission half-shaft of the second machine head 50 is assembled within 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 can change and flip under the drive of the can change mechanism 70.

[0104] The handpiece reciprocating mechanism 40 includes a reciprocating drive 410 and a push plate 420. The reciprocating drive 410 is mounted on the frame 10, and the push plate 420 is connected to the reciprocating drive 410. The push plate 420 is driven by the reciprocating drive 410 to perform linear reciprocating motion. The push plate 420 is provided with a drive jaw 4210 for engaging the first pusher head 2310 and the second pusher head. The drive jaw 4210 is used to engage the first pusher head 2310 or the second pusher head to achieve linear reciprocating drive of the first handpiece 20 or the second handpiece 50.

[0105] The driving jaws 4210 are open structures, which can allow the first pusher head 2310 or the second pusher head to perform a barrel-changing and flipping action.

[0106] When the two heads are flipped under the action of the bobbin changing mechanism 70, the first pusher head 2310 or the second pusher head can enter the driving clamp 4210, and then the reciprocating drive device 410 drives the first head 20 or the second head 50 to perform linear reciprocating motion together. When the winding head is full of bobbins, the current pusher head (the first pusher head 2310 or the second pusher head) can rotate under the action of the bobbin changing mechanism 70 to rotate the other pusher head (the second pusher head or the first pusher head 2310) into the driving clamp 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 screw. The reciprocating motor 4110 is assembled on the frame 10 and is transmission-connected to the reciprocating transmission screw. The reciprocating push slide 4120 is assembled on the reciprocating transmission screw through a threaded transmission, and the push plate 420 is connected to the reciprocating push slide 4120. When the reciprocating motor 4110 rotates forward or reverse, it can drive the push plate 420 to perform linear reciprocating motion.

[0108] The assembly position of the die reciprocating mechanism 40 should be able to meet the requirements of linear reciprocating drive of the die in the winding station of the wire drawing machine. Regardless of which die is in the winding station of the wire drawing machine, the current die can be linearly reciprocated through the movable drive connection between the drive clamp 4210 and the current pusher (the second pusher or the first pusher 2310).

[0109] The guide mechanism 80 includes an open annular guide ring 810, which includes a front guide plate 8130 and a rear guide plate 8140. The front and rear guide plates are integrally connected by a fixing sleeve 8150 and fixed to the frame 10. A guide slot 8110 is defined between the front and rear guide plates. A guide opening 8120 is formed in the guide ring 810 at a location corresponding to the drive jaws 4210. The barrel changing spindle 730 passes through the hollow portion of the inner ring of the guide ring 810.

[0110] When the two die heads are flipped during a bobbin change, the die reciprocating mechanism 40 first drives the pusher head of the current die head (the first pusher head 2310 or the second pusher head) into the guide groove 8110. At this point, both pusher heads are within the guide groove 8110. The die changing mechanism 70 then starts flipping to complete the bobbin change operation. After the bobbin change, the pusher head of the empty die head is within the drive clamp 4210, and the empty die head starts rotating. Simultaneously, the die reciprocating mechanism 40 drives the empty die head in a linear reciprocating motion, continuing the wire drawing and winding process.

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

[0112] The control method of the semi-shaft driven reciprocating wire drawing machine for coarse and fine yarns disclosed in this application is as follows:

[0113] In the winding step, the glass fiber yarn is pulled to the current winding head by the slow pulling mechanism, captured by the upper wire hook and wound on the upper wire ring, and pushed to the winding position by the yarn pushing rod for drawing and winding;

[0114] In the reciprocating winding step, the head reciprocating mechanism 40 is started, and the push disk 420, under the action of the reciprocating drive device 410, drives the current winding head to make a linear reciprocating motion on its corresponding spline auxiliary support seat through the cooperation between the driving clamp 4210 and the push head of the current winding head, thereby winding the glass fiber yarn on the current winding head;

[0115] In the yarn cutting step, the yarn cutting mechanism cooperates with the yarn cutting groove on the upper yarn ring to cut off the connection between the yarn ball or yarn cake and the transition yarn;

[0116] In the barrel changing step, after the current machine head is fully wound, the machine head reciprocating mechanism 40 first drives the pusher head of the full-barrel machine head to the guide groove 8110; then the barrel changing mechanism 70 is started, driving the first machine head 20 and the second machine head 50 to rotate to flip the empty-barrel machine head to the winding station of the wire drawing machine. When the machine head is flipped, the first pusher head 2310 and the second pusher head rotate in the guide groove 8110 at the same time; then the machine head reciprocating mechanism 40 is started, driving the current winding machine head to perform linear reciprocating motion to continue drawing and winding.

[0117] In a variant embodiment of the present application, the first pusher head 2310 is further provided with a first push slider 2311 and a first push pin 2312. The second pusher head is further provided with a second push slider and a second push pin. The sliding fit between the first push slider 2311, the second push slider, and the inner wall of the guide ring 810 can reduce resistance during the handpiece flipping motion and increase the smoothness of the handpiece flipping motion.

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

[0119] When the glass fiber filaments to be drawn and wound are spun yarn, the first head 10 can be configured to further include a first aluminum drum 240, a first sealing ring sleeve 250, a first upper wire ring 260, a front end cover, and a rear end cover. The first aluminum rotating cylinder 240 is provided with a first rotating cylinder main shaft hole 2410, and one end of the first rotating cylinder main shaft hole 2410 is provided with a first sleeve groove 2420; the first sealing ring sleeve 250 is provided with a first sleeve assembly main shaft hole 2510 and a first support seat accommodating cavity 2520; the first upper wire ring 260 is fixed to the front end of the first aluminum rotating cylinder 240, 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 upper wire ring 260 are fixedly connected; the first spline sub-support seat 320 can be slidably accommodated in the first support seat accommodating cavity 2520.

[0120] When the machine head changes the barrel and flips, the first transmission half-shaft 210, the first transmission half-shaft motor 220, the first pushing motor seat 230, the first aluminum rotating drum 240, the first sealing ring sleeve 250, and the first upper wire ring 260 can flip synchronously; when the wire drawing machine head performs 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 drum 240, the first sealing ring sleeve 250, and the first upper wire ring 260 can perform linear reciprocating motion synchronously.

[0121] When the first machine head 20 performs linear reciprocating motion, the first sealing ring sleeve 250 and the first splined auxiliary support seat 320 produce corresponding linear motion coordination. The first sealing ring sleeve 250 not only increases motion stability, but also reduces the degree of wear between the first splined auxiliary support seat 320 and the first aluminum drum 240, and facilitates replacement. Furthermore, the first sealing ring sleeve 250 prevents external debris, such as oil, debris, and wool, from entering the interior of the first machine head 20 during its reciprocating motion.

[0122] Corresponding to the first head 20 , the second head 50 also includes the same head structure and connection and matching relationship, which will not be described in detail here.

[0123] When the glass fiber used in the drawing and winding process is coarse yarn, the first and second machine heads 20 and 50 also need to be equipped with expansion plates and expansion and contraction mechanisms to meet the production requirements of coarse yarn. Taking the first machine head 20 as an example, the first machine head 20 also includes a first expansion plate 270 and a first end contraction mechanism 280.

[0124] See also Figure 5 The first aluminum drum 240 is also provided with a first latching position 2430. The connection portion of the first expansion plate 270 has a mechanism that mates with the first latching position 2430. When the first expansion plate 270 is movably engaged with the first latching position 2430, this movable engagement connection prevents the expansion plate 270 from radially falling off the first aluminum drum 240. For details on the movable engagement connection, please refer to the Chinese patent: "A Support Device for the Intermediate Conical Sleeve of a Die Head Expansion Plate" (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] The first aluminum rotating cylinder 240 is further provided with a first end assembly position 2440 and a first air hole 2470 .

[0127] The first end assembly positions 2440 can be respectively set 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 set 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 disposed within the first end assembly position 2440. A first mating tapered surface 2710 is provided at a corresponding portion of the first expansion piece 270, mating with the first end cone sleeve 2810. The first air hole 2470 is connected to the first end assembly position 2440. When compressed air enters the first end assembly position 2440 through the first air hole 2470, it drives the first end cone sleeve 2810 to release the first mating tapered surface 2710, causing the expansion piece to contract. Simultaneously, it causes the first end cone sleeve 2810 to compress the first end cone sleeve spring 2820. When the compressed air is shut off, the first end cone sleeve spring 2820 drives the first end cone sleeve 2810 to press against the first mating tapered surface 2710, causing the expansion piece to expand.

[0129] In a variation of the present application, the first end telescopic mechanism 280 also includes a first expansion plate tension spring, which is wrapped around several first expansion plates 270, or a first expansion plate tension spring groove is provided on the first expansion plate 270, and the first expansion plate tension spring is provided in the first expansion plate tension spring groove to provide radial contraction force for the first expansion plate 270.

[0130] For the interaction between the first end cone sleeve 2810, the first end cone sleeve spring 2820, the first air hole 2470, and the first matching cone surface 2710, please refer to the Chinese patent: A machine head expansion piece intermediate cone sleeve support device publication number CN213803526U, which will not be repeated here.

[0131] For a typical die spindle, installing sheet expansion and retraction mechanisms at both ends of the die spindle is sufficient to efficiently achieve automatic expansion and retraction switching of the sheet. However, for the die reciprocating wire drawing machine involved in this application, since the die spindle is relatively long, installing sheet expansion and retraction mechanisms only at both ends would affect the efficiency and control accuracy of sheet expansion. Therefore, this application adds a central sheet expansion and retraction mechanism in the middle of the aluminum drum. Accordingly, the first die and the second die also include a first central retraction mechanism 290 and a second central retraction mechanism, respectively.

[0132] See also Figure 6 and Figure 7 The first aluminum rotating cylinder 240 is also provided with a first middle assembly position 2450 and a first pull rod hole 2460.

[0133] The first central telescopic mechanism 290 includes a first pull rod 2910, a first sloped 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 sloped 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 disposed within the first central assembly position 2450. The first pull rod 2910 is disposed within the first pull rod hole 2460, with its ends connected to the first end taper sleeve 2810 and the first slider movable seat 2930, respectively.

[0134] The first connecting rod seat 2950 is fixedly assembled in the first middle assembly position 2450 , and both ends of the first slider connecting rod 2940 are movably connected to the first connecting rod seat 2950 and the first slope slider 2920 .

[0135] The first slider movable seat 2930 is provided with a plurality of first movable seat driving inclined grooves 2931, and the first slope slider 2920 is slidably assembled in the first movable seat driving inclined grooves 2931. The first slope slider 2920 is slidably engaged with the inclined groove bottom of the first movable seat driving inclined groove 2931 through its first matching slope 2921.

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

[0137] At the same time, when lifting the expansion piece, 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 displacing on the expansion piece in a direction parallel to the first machine head 20 when pushed by the first movable seat driving inclined groove 2931, further ensuring the efficiency of the expansion piece extension. In addition, during the process of lifting the expansion piece, the first slider connecting rod 2940 can also provide radial support force to the first ramp slider 2920. A portion of the reaction force from the expansion piece is borne by the first slider connecting rod 2940, thereby balancing the force on the first slider movable seat 2930 and improving the stability of the expansion piece extension action.

[0138] The movable connection between the first slider connecting rod 2940, the first connecting rod seat 2950, ​​and the first sloped slider 2920 is as follows: the first slider connecting rod 2940 includes a first connecting rod portion 2941 and first spherical connecting rod heads 2942 disposed at both ends of the first connecting rod portion 2941. The first connecting rod seat 2950 is provided with a first connecting rod seat head receiving position 2951, which defines a first connecting rod seat head movable opening 2952. The first sloped slider 2920 is provided with a first slider head receiving position 2922, which defines a first slider head movable opening 2923. The first spherical connecting rod heads 2942 at both ends of the first connecting rod portion 2941 are movably inserted into the first connecting rod seat head receiving position 2951 and the first slider head receiving position 2922, respectively.

[0139] When the first end cone sleeve 2810 loosens 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 move synchronously through the first pull rod 2910, so that the first slider movable seat 2930 loosens the first slope slider 2920, so that the first expansion 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 slope slider 2920 through the first pull rod 2910, so that the first slope slider 2920 presses against the first expansion piece 270, and the first expansion piece 270 automatically expands.

[0140] Through the coordination of the first end telescopic mechanisms 280 at both ends and the first middle telescopic mechanism 290 in the middle, the first expansion plate 270 can be automatically controlled to switch between telescopic and expansion by controlling the compressed air. This makes the semi-shaft-driven reciprocating drawing machine for coarse and fine yarns disclosed in this application suitable for the production of glass fiber roving.

[0141] In a variation of the present application, the first middle telescopic mechanism 290 also includes a first slope slider spring, a first slider spring groove is provided on the first slope slider 2920, the first slope slider spring is provided in the first slider spring groove and surrounds several first slope sliders 2920, and is used to provide radial contraction force of the first slope 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 described in detail 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 has the first transmission half-shaft flange 2100, the first rotating bearing seat 2200, and the first bearing sleeve shaft 2300 disposed at the 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 drum 240, and the first upper wire ring 260 are fixedly connected. The first oil circuit is connected to the first bearing sleeve 2300. By configuring the first bearing sleeve 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 function of the second machine head 50 and the first machine head 20 are the same as those of the first machine head 20 and will not be repeated here.

[0144] In order to cooperate with the yarn unloading and pushing cylinder of the head reciprocating wire drawing machine for coarse and fine yarns with a semi-axial transmission, a variant embodiment of the present application also involves an automatic pushing cylinder mechanism that can adapt to the head reciprocating wire drawing machine.

[0145] See also Figure 8 and Figure 9 The die reciprocating wire drawing machine further comprises a first barrel pushing mechanism and a second barrel pushing mechanism 90. The first barrel pushing mechanism and the second barrel pushing mechanism 90 are used to complete the barrel pushing work of the first die 20 and the second die 50 respectively.

[0146] The following describes the second cylinder pushing mechanism 90 as an example.

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

[0148] The second barrel pushing cylinder 910 is fixedly mounted on the barrel changing turntable 710, and the second barrel pushing plate 920 is fixedly connected to the piston shaft of the second barrel pushing cylinder 910. The second head matching portion 9210 has a structure and size matching that of the second head 50 and is fitted to the second head 50.

[0149] The second barrel pushing plate 920, under the action of the second barrel pushing cylinder 910, pushes the bobbin on the second machine head 50. Because the second barrel pushing cylinder 910 is located 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 existing barrel pushing solutions in which the barrel pushing mechanism is located elsewhere than on the barrel changing turntable 710, this solution has the advantages of high barrel pushing efficiency and a 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-cylinder mechanism 90 and the second push-cylinder 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 feeding 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-cylinder mechanism 90 and the second push-cylinder 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 variant embodiment of the present application, a semi-axially driven reciprocating drawing machine for coarse and fine yarns further includes an auxiliary ejection device 200, which includes an auxiliary ejection seat 2010 and an auxiliary ejection mechanism 2020. The auxiliary ejection seat 2010 is provided with an ejection drive opening 2011, which is used to receive the driving force from the auxiliary ejection mechanism 2020 and drive the auxiliary ejection seat 2010 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). The auxiliary ejection motor 2021 is mounted on the frame 10 and is transmission-connected to the auxiliary ejection screw. The auxiliary ejection slide 2022 is mounted on the auxiliary ejection screw via a threaded transmission connection, and the auxiliary ejection seat 2010 is fixedly connected to the auxiliary ejection slide 2022. When the auxiliary ejection motor 221 rotates forward or reverse, it can drive the auxiliary ejection seat 2010 to perform linear reciprocating motion.

[0153] The ejection drive opening 2011 pushes the first handpiece 20 or the second handpiece 50 by cooperating with the first pusher head 2310 on the first handpiece 20 or the second pusher head on the second handpiece 50. The structure of the ejection drive opening 2011 and the driving cooperation relationship between the ejection drive opening 2011 and the pusher head are the same as the structure of the driving clamping opening 4210 in the handpiece reciprocating mechanism 40 and the driving cooperation relationship between the ejection drive opening 2011 and the pusher head, and are not further described here.

[0154] Similar to the aforementioned guide opening 8120, an auxiliary guide opening 8160 is provided on the guide mechanism 80 at a location corresponding to the movement of the ejection drive opening 2011. When the auxiliary ejection device 200 drives the first machine head 20 or the second machine head 50 to return, the auxiliary ejection seat 2010 drives the first ejector head 2310 or the second ejector head through the auxiliary guide opening 8160 and returns to the guide groove 8110.

[0155] In a modified embodiment of the present application, the auxiliary ejection mechanism 2020 may also be a pneumatic or hydraulic component such as an air cylinder or an oil cylinder.

[0156] When producing roving, the auxiliary ejection device 200 is an auxiliary ejection mechanism of the unloading robot. The unloading robot can hold the outer circle of the yarn cake and automatically unload the yarn (take out the yarn ball) through the auxiliary ejection device 200. The unloading steps can be:

[0157] The machine head extends to deliver the yarn, and the auxiliary ejection device 200 pushes the full-bobbin machine head (the first machine head 20 or the second machine head 50) forward to deliver the yarn;

[0158] The robot supports the yarn, and the yarn unloading robot comes to the lower side of the yarn ball and moves upward to support the yarn ball;

[0159] The machine head retracts to unload the yarn, and the auxiliary pushing device 200 drives the machine head back to the initial position (that is, the standby position), and the yarn ball is carried on the yarn unloading robot.

[0160] The aforementioned movement of the machine head extending to deliver the yarn and the movement of the manipulator reaching the lower side of the yarn ball can be performed successively or simultaneously.

[0161] The complete control method of the head reciprocating wire drawing machine for coarse and fine yarns with a half-shaft drive and an auxiliary ejection device 200 is as follows:

[0162] In the winding step, the glass fiber yarn is pulled to the current winding head by the slow pulling mechanism, captured by the upper wire hook and wound on the upper wire ring, and pushed to the winding position by the yarn pushing rod for drawing and winding;

[0163] In the reciprocating winding step, the reciprocating mechanism of the machine head is started, and the push disk, under the action of the reciprocating drive device, drives the current winding machine head (first machine head or second machine head) to make a linear reciprocating motion on its corresponding spline sub-support seat (first spline sub-support seat or second spline sub-support seat) through the cooperation between the driving clamp and the push head (first push head or second push head) of the current winding machine head to wind the glass fiber yarn on the current winding machine head;

[0164] In the yarn cutting step, the yarn cutting mechanism cooperates with the yarn cutting groove on the upper yarn ring to cut off the connection between the yarn ball or yarn cake and the transition yarn;

[0165] In the bobbin changing step, after the current head is full of wire, the head reciprocating mechanism first drives the pusher head (the first pusher head or the second pusher head) of the full-bobbin head to the guide groove; then the bobbin changing head is started, driving the first head and the second head to flip over 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, driving the current winding head (the first head or the second head) to do a linear reciprocating motion to continue drawing and winding;

[0166] In the bobbin unloading step, the auxiliary pushing device pushes the full bobbin head (the first head or the second head) forward to deliver the yarn; the yarn unloading robot comes to the lower side of the yarn ball and moves upward to support the yarn ball; the auxiliary pushing device drives the head after the full bobbin is unloaded to return to the initial position (the push head of the head returns to the guide ring after the full bobbin is unloaded), and the yarn ball is carried on the yarn unloading robot.

[0167] In terms of control methods, the differences between the present 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 below:

[0168] In the reciprocating winding step, the push disk, under the action of the reciprocating drive device, drives the current winding head to make a linear reciprocating motion on its corresponding spline auxiliary support seat through the cooperation between the driving clamp and the push head of the current winding head;

[0169] In the bobbin changing step, the die reciprocating mechanism first drives the pusher head of the full-bobbin die to the guide groove; then the die changing mechanism starts, driving the two die heads to flip and turn the empty-bobbin die head to the winding station of the wire drawing machine; the die reciprocating mechanism starts, driving the empty-bobbin die head to make a linear reciprocating motion to continue drawing and winding;

[0170] In the unloading step, the auxiliary ejection device pushes the full-bobbin head forward to deliver the yarn; the yarn unloading robot comes to the lower side of the yarn ball and holds the yarn ball upward; the auxiliary ejection device drives the full-bobbin head back to the initial position, and the yarn ball is carried on the yarn unloading robot.

[0171] In a modified embodiment of the present application, the semi-axial driven reciprocating drawing machine for both coarse and fine yarns also adopts a multi-section combined expansion plate for the long head and its corresponding drawing machine head. Figure 12 The multi-segmented modular expansion unit comprises several expansion units 2400. The center expansion unit 2400 is provided with a recessed socket 2401 and a protruding plug 2402 at each end. The expansion units 2400 are extended by interlocking the recessed sockets 2401 and protruding plugs 2402, thus forming a multi-segment modular expansion unit. The expansion units 2400 on either side may be provided with either a recessed socket 2401 or a protruding plug 2402 at only one end.

[0172] The current trend in glass fiber drawing is towards large, multi-section drawing with large bushings. This results in longer expansion plates, which, due to centrifugal force, must be lightweight. However, this reduction in weight inevitably compromises rigidity and straightness, making them more susceptible to bending and deformation after hardening. This can lead to uneven openings, causing slippage in the plastic winding drum. Alternatively, bulging can cause faults within the yarn cake, impacting downstream reduction. This presents significant challenges in expanding the plates. A multi-section expansion plate design, coupled with a continuous chain, would address these issues. The concave-convex joints at the expansion plate joints ensure that each expansion plate is synchronized and self-adjusting, ensuring that each plastic winding drum receives the appropriate tension.

[0173] The components or parts used in conjunction with the multi-stage combined expansion film also include an aluminum drum, a front cover, a rear cover, an upper wire ring, etc. Similar to the aforementioned first head 20 and the second head 50, the connection between the expansion film unit 2400 and the aluminum drum is also adopted. Figure 5 The movable snap-in connection shown, the connection and assembly between the aluminum drum, the front cover, the rear cover, the upper wire ring, and the multi-section combined expansion piece are similar to those described above and will not be described in detail here.

[0174] Unlike the aforementioned end and middle telescopic mechanisms, this embodiment utilizes a multi-stage modular structure, allowing for the expansion and contraction of the sheet. A spring hole 2403 is provided in the center of each expansion unit 2400 on the aluminum drum, and a sheet expansion spring is located within each spring hole 2403. This spring provides driving force for the expansion units 2400, reducing the complexity of the machine head.

[0175] 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.
