Description

Technical Field

[0001] This utility model relates to the field of wire winding machines, and in particular to a wire winding machine that can automatically clamp and change wire shafts. Background Technology

[0002] In the application of wire coiling machines, traditional equipment has significant shortcomings in automating shaft changing and wire cutting. Currently, shaft changing and wire cutting operations largely rely on manual intervention, which is not only inefficient but also prone to introducing operational errors, negatively impacting production efficiency and product quality, as detailed below:

[0003] First, traditional wire winding machines have a low level of automation, mainly due to the need for manual operation in the shaft changing and wire cutting processes. Manual operation is not only slow but also prone to errors, leading to low production efficiency and inconsistent product quality. Furthermore, manual intervention increases the safety risks for operators, especially when working near a high-speed wire winding machine.

[0004] Secondly, existing filament winding machines suffer from reliability issues in filament clamping and transfer. Traditional filament clamping devices typically employ simple mechanical clamping methods, which struggle to stably clamp the filament bundle during shaft changes, leading to easy loosening or breakage of the filament bundle and impacting product quality and production continuity. Furthermore, filament guide devices often fail to accurately guide the filament bundle into the clamping device during shaft changes, resulting in filament misalignment or entanglement, increasing equipment failure rates and maintenance costs.

[0005] Finally, the cutting effect is poor. When traditional cutting devices cut filament bundles, inaccurate cutting position or uneven cutting force results in uneven filament bundle cuts, affecting product quality.

[0006] In summary, existing wire winding machines suffer from numerous problems in automated shaft changing and wire cutting, severely impacting production efficiency, product quality, and equipment reliability. These issues urgently require technological innovation to address, in order to meet the demands of modern industrial production for efficient, stable, and automated wire winding equipment. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this utility model provides a wire winding machine with automatic wire clamping and shaft changing. Through the coordinated work of hook knife, steering rod, wire clamping shaft sleeve and cutting device, automatic shaft changing and wire cutting are achieved. This significantly improves the automation level of the wire winding machine, reduces manual intervention, improves production efficiency and safety, and avoids errors and risks that may be caused by manual operation.

[0008] This utility model achieves the above-mentioned technical objectives through the following technical means.

[0009] An automatic wire-clamping and spool-changing winding machine includes a frame, a turret roller, and a transmission system. The turret roller supports at least two spindles, which are driven to rotate via the transmission system for winding. The turret roller is mounted on the frame via a rotary support and is driven to revolve by a third motor. The machine also includes a wire-clamping and spool-changing device, comprising a clamping sleeve, a hook knife, a steering rod, and a cutting device. The steering rod is mounted on the turret roller. The clamping sleeve is installed in the air-filled area of ​​the spindle and rotates with the spindle. The clamping sleeve is used to clamp the wire bundle during spool-changing.

[0010] The hook blade is located on the path of the filament bundle entering the clamping sleeve, and is used to guide the filament bundle into the clamping sleeve; the cutting device is installed on the turret roller and located near the clamping sleeve, and is used to cut the filament bundle after it is straightened.

[0011] Furthermore, the wire-clamping bushing includes a first washer and a second washer, which are fitted onto the outer ring of the spindle shaft; the outer side of the first washer has a positive stop, and the outer side of the second washer has a reverse stop, which cooperate to form a wire-clamping gap.

[0012] Furthermore, a V-shaped notch is provided on one side of the mating of the forward stop and the reverse stop to guide the filament bundle into the filament clamping gap.

[0013] Furthermore, the inflation zone of the spindle includes a shaft end sliding sleeve and a shaft end fixed sleeve. The first washer is sleeved on the shaft end fixed sleeve, and the second washer is sleeved on the shaft end sliding sleeve. Inflation causes the shaft end sliding sleeve to move toward the shaft end fixed sleeve, thereby clamping the first washer and the second washer together. A first reset mechanism is installed between the second washer and the shaft end sliding sleeve.

[0014] Furthermore, an anti-collision rotation reset mechanism is installed at the bottom of the hook blade to prevent the hook blade from colliding with the spindle shaft during the spindle shaft rotation process.

[0015] Furthermore, the anti-collision rotation reset mechanism includes a connecting rod, a contact block, and a second reset mechanism; the connecting rod is supported on the frame, a hook knife is installed at one end of the connecting rod, and a contact block is connected to the connecting rod. One end of the contact block extends to the rotation path of the turret roller. An external force is applied during the rotation of the turret roller to cause the contact block to rotate, thereby causing the hook knife to avoid the rotation path of the spindle shaft change; a second reset mechanism is provided between the frame and the contact block to reset the hook knife after the external force disappears.

[0016] Furthermore, the cutting device includes a cutter holder and a blade. The cutter holder is mounted on a turret roller between the hook cutter and the wire clamping sleeve, and the blade is mounted on the cutter holder.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Existing wire winding machines include a frame 1, a turret roller 2, and a transmission system 5. The turret roller 2 supports at least two spindles, which are driven to rotate via the transmission system 5 for winding. The turret roller 2 is mounted on the frame 1 via a rotary support and is driven to revolve by a third motor 6. The transmission system 5 is a commonly used transmission system in existing wire winding machines. Figure 1 As shown, the automatic wire-clamping and shaft-changing winding machine of this utility model, based on the existing wire winding machine, further includes a wire-clamping and shaft-changing device. This device includes a wire-clamping shaft sleeve 10, a hook knife 8, a steering rod 12, and a cutting device. The steering rod 12 is mounted on the turret drum 2 and is used to straighten the wire bundle during shaft changing. The wire-clamping shaft sleeve 10 is installed in the air-expanding area of ​​the shaft and rotates with the shaft. The wire-clamping shaft sleeve 10 is used to clamp the wire bundle during shaft changing. The hook knife 8 is located on the moving path of the wire bundle entering the wire-clamping shaft sleeve 10 and is used to guide the wire bundle into the sleeve. The cutting device is mounted on the turret drum 2 and located near the wire-clamping shaft sleeve 10, and is used to cut the wire bundle after it has been straightened. The shaft is a conventional structure; publication number CN115057304A describes a shaft including a shaft-end sliding sleeve and a shaft-end fixed sleeve, where air expansion causes the shaft-end sliding sleeve to move towards the shaft-end fixed sleeve.

[0037] Implementation, for example Figure 2 and Figure 3 As shown in the embodiment, the turret roller 2 supports two spindle shafts. The turret roller 2 is equipped with a first sleeve 2-1, a second sleeve 2-2, and a central sleeve 2-3. The first sleeve 2-1 supports the first spindle shaft 3, and the second sleeve 2-2 supports the second spindle shaft 4. The first sleeve 2-1 and the second sleeve 2-2 are evenly distributed on the turret roller 2. The central sleeve 2-3 is located at the center of rotation of the turret roller 2. The turret roller 2 is supported and mounted on the frame 1 by a slewing bearing, and is driven to revolve by a third motor 6 via belt drive. Figure 3 and Figure 4 As shown, the transmission system 5 includes a central shaft 5-1, a hollow shaft 5-2, a first belt drive, a second belt drive, a third belt drive, a fourth belt drive, a first motor 5-3, and a second motor 5-4. One end of the central shaft 5-1 is supported in the central sleeve 2-3, and the inner cavity of the hollow shaft 5-2 is supported at the other end of the central shaft 5-1 by bearings. The first motor 5-3 and the second motor 5-4 are respectively mounted on the motor platform 7, which is connected to the frame 1 by support columns. The first motor 5-3 drives the central shaft 5-1 to rotate through the first belt drive. The central shaft 5-1 is connected to the first spindle shaft 3 through the third belt drive. The rotation of the central shaft 5-1 by the first motor 5-3 drives the rotation of the central shaft 5-1, which in turn drives the rotation of the first spindle shaft 3, thus realizing the rotation of the first spindle shaft 3. The second motor 5-4 drives the hollow shaft 5-2 to rotate via a second belt drive. The hollow shaft 5-2 is connected to the second spindle shaft 4 via a fourth belt drive. The second motor 5-4 drives the hollow shaft 5-2 to rotate, which in turn drives the second spindle shaft 4 to rotate, thus achieving the rotation of the second spindle shaft 4. During the single-axis winding process, only the first motor 5-3 or the second motor 5-4 needs to be driven individually, i.e., only the first spindle shaft 3 or the second spindle shaft 4 needs to be driven individually. During the shaft changing process, both the first motor 5-3 and the second motor 5-4 need to be driven simultaneously, so that the first spindle shaft 3 and the second spindle shaft 4 rotate at the same time.

[0038] Figure 1 and Figure 2It can be seen that one side of the turret roller 2 has a first sleeve 2-1, a second sleeve 2-2, and a central sleeve 2-3, which is designated as the transmission side. The other side of the turret roller 2 is the winding side. One end of the spindle shaft is located on the transmission side for connection with the transmission system 5, while the other end of the spindle shaft passes through the turret roller 2 and enters the winding side for winding the wire. The wire clamping and shaft changing device includes a wire clamping shaft sleeve 10, a hook knife 8, a steering rod 12, and a cutting device. The steering rod 12 is installed on the winding side of the turret roller 2, that is, on the same surface as the other end of the spindle shaft. In the embodiment, two steering rods 12 are provided between the two sides of the first spindle shaft 3 and the second spindle shaft 4. The two steering rods 12, the first spindle shaft 3, and the second spindle shaft 4 are located on the same pitch circle of the turret roller 2. The phase difference between the steering rod 12 and the first spindle shaft 3 and the second spindle shaft 4 is 90 degrees. During the spindle shaft changing process, the steering rod 12 can straighten the wire bundle, such as... Figure 7 As shown, the purpose of straightening is to increase the angle at which the filament enters the clamping sleeve 10 (which can be understood as the cutting angle) to allow the filament to enter the clamping sleeve 10 better; the clamping sleeve 10 is installed in the air expansion zone of the spindle, and the clamping sleeve 10 rotates with the spindle. The clamping sleeve 10 is used to clamp the filament during the spindle changing process; the hook knife 8 is located on the moving path of the filament entering the clamping sleeve 10, and guides the filament into the clamping sleeve 10 smoothly; the cutting device is installed on the turret roller 2 and located near the clamping sleeve 10, and is used to cut the filament after it is straightened.

[0039] like Figure 5 As shown, the wire clamping sleeve 10 includes a first washer 10-1 and a second washer 10-2, which are fitted onto the outer ring of the spindle shaft. The inflation zone of the spindle shaft includes a shaft end sliding sleeve and a shaft end fixed sleeve. The first washer 10-1 is fitted onto the shaft end fixed sleeve, and the second washer 10-2 is fitted onto the shaft end sliding sleeve. Inflation causes the shaft end sliding sleeve to move toward the shaft end fixed sleeve, thereby clamping the first washer 10-1 and the second washer 10-2. A disc spring 14 is installed between the second washer 10-2 and the shaft end sliding sleeve. After the inflation disappears, the shaft end sliding sleeve is reset, thus loosening the first washer 10-1 and the second washer 10-2, making it easier to remove the clamped wire bundle. The first washer 10-1 has a forward stop 10-3 on its outer contour, and the second washer 10-2 has a reverse stop 10-4 on its outer contour. The forward stop 10-3 and the reverse stop 10-4 cooperate to form a wire-clamping gap. A V-shaped notch 10-5 is provided on the mating side of the forward stop 10-3 and the reverse stop 10-4 to guide the wire bundle into the wire-clamping gap.

[0040] like Figure 3As shown, an anti-collision rotation reset mechanism is installed at the bottom of the hook cutter 8 to prevent the hook cutter 8 from colliding with the spindle shaft during rotation. The anti-collision rotation reset mechanism includes a connecting rod 9, a contact block 13, and a second reset mechanism. The connecting rod 9 is supported on the frame 1 by a bushing, allowing it to rotate. One end of the connecting rod 9 is fitted with the hook cutter 8, which has an adjustable U-shaped groove to adjust its insertion position. The other end of the connecting rod 9 is located on the turret drum drive side, and the other end is connected to the contact block 13, which is made of non-metallic material. One end of the contact block 13 extends onto the rotation path of the turret drum 2. External force is applied during the rotation of the turret drum 2, causing the contact block 13 to rotate, thus preventing the hook cutter 8 from colliding with the spindle shaft during rotation. A second reset mechanism is provided between the frame 1 and the contact block 13 to reset the hook cutter 8 after the external force disappears. The second reset mechanism is typically a tension spring. Figure 7 As shown, the dotted hook 8 represents the extreme position of the contact block 13 after rotation. By resetting the hook 8, the external force generated by the resetting of the hook 8 is applied to the filament bundle, causing the filament bundle to move inward and enter the filament clamping sleeve 10.

[0041] like Figure 6 As shown, the cutting device includes a cutter holder and a blade 11. The cutter holder is mounted on the turret roller 2 between the hook cutter 8 and the wire clamping sleeve 10, and the blade 11 is mounted on the cutter holder.

[0042] The working principle is as follows:

[0043] like Figure 7 As shown, when the yarn bundle on the first spindle 3 is fully wound, the third motor 6 starts, driving the turret roller 2 to begin rotating. As the turret roller 2 rotates, the first spindle 3 gradually disengages from the winding position of the yarn bundle. Since the steering rod 12 is mounted on the turret roller 2, it rotates with the turret roller 2. When the steering rod 12 contacts the yarn bundle, it keeps the yarn bundle in a straight line. During the spindle changing process, both the first spindle 3 and the second spindle 4 rotate independently.

[0044] When the second spindle 4 rotates to the winding position, the filament passes through the first spindle 3 and the steering rod 12 to reach the vicinity of the second spindle 4. At this time, due to the presence of the hook knife (8), it guides the filament into the clamping gap of the clamping sleeve 10. The air expansion device causes the shaft end sliding sleeve to move towards the shaft end fixed sleeve, thereby causing the first washer 10-1 and the second washer 10-2 to squeeze each other and clamp the filament. This process ensures that the filament is stably clamped during the spindle changing process, avoiding loosening or breakage. Before the filament is straightened, it contacts the blade 11 of the cutting device. As the filament is straightened, it moves towards the cutting edge of the blade 11 after being stressed, thus cutting the filament by the blade 11, completing the automatic spindle changing and filament cutting.

[0045] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0046] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. All equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included within the scope of protection of the present utility model.
