Abstract
Description
Technical Field
[0001] The utility model relates to a winding device. Background Art
[0002] After melt spinning, the filaments are wound up in a winding device. A winding device comprises a winding turret and two elongated, protruding winding spindles spaced apart from each other. The winding spindles are rotatably mounted in the winding turret. By rotating the winding turret, the winding spindles can be alternately guided between the working area and the replacement area.
[0003] After the winding spindle located in the working area completes winding, the winding turntable is driven to rotate a certain angle, and then the winding spindle enters the replacement area, and another winding spindle enters the working area.
[0004] The packages entering the winding spindle change area have a serious flying phenomenon. The larger the denier of the wound filament, the more obvious this phenomenon is. Utility Model Content
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0006] According to some embodiments of the present invention, a winding device comprises a winding turntable, two winding spindles spaced apart from each other and elongated and protruding, and a first base, wherein the winding spindles are arranged on the winding turntable, one of the winding spindles is located in the working area, and the other is located in the replacement area, the first base is located on the lower side of the winding spindle, and a baffle comprising two split plates can be folded and unfolded on the first base, the winding device further comprises a second base and a lifting device, the second base and the lifting device are located on the other side below the winding spindle in the replacement area, a left guard plate portion with a bending section is arranged between the first base and the winding spindle in the replacement area and extends between the baffle and the winding spindle in the replacement area, and a right guard plate portion with a bending section is arranged between the lifting device and the winding spindle in the replacement area.
[0007] The left guard plate prevents the filament end from colliding with the sharp parts of the first base and prevents the filament end from entering between the two split plates of the spoiler.

BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Attachment Figure 1 It is a side view of the winding device of the present invention in working state;
[0012] Attachment Figure 2 It is a side view of the winding device of the present invention in the spinning state. DETAILED DESCRIPTION
[0013] The winding device in this embodiment is shown in the attached Figure 1 and attached Figure 2 As shown. Figure 1 It is a side view of the winding device of the utility model in working state. Figure 2 This is a side view of the winding device of the present invention in the spinning state. Winding spindles 2 and 3 are eccentrically rotatably mounted on a winding turntable 1. An unillustrated electric motor drives the winding spindle 2. A cantilevered winding spindle 3 is eccentrically rotatably mounted on the winding turntable 1, offset approximately 180 degrees from the winding spindle 2. The winding spindle 2 supports an empty bobbin. Similarly, an unillustrated electric motor drives the winding spindle 3. The winding spindles 2 and 3 can be switched between a working area and a replacement area.
[0014] The winding turntable is rotatably mounted on the frame of the winding device, and can be swung clockwise by a driving mechanism.
[0015] In order to accommodate the bobbins 10, the winding spindles 2, 3 each have a plurality of winding tubes on their circumferences, which are clamped on the circumferences of the winding spindles 2, 3. The free ends of the winding spindles 2, 3 protrude toward a doffing gallery for taking out and sending away the bobbins.
[0016] Attachment Figure 1The winding spindle 3 is in the replacement area, and the full bobbin thereon will be replaced with an empty winding bobbin; the winding spindle 2 is in the working area, and the filament is wound on the winding bobbin thereon.
[0017] Attachment Figure 1 The figure shows the winding turret 1 after it has completed its rotation. The winding spindle 3, carrying a full bobbin 10, has moved to the standby position, while the winding spindle 2, carrying an empty bobbin, has moved to the winding operating position to begin filament winding. The driving source for the full bobbin 10 is deactivated, and the full bobbin 10 continues to rotate due to inertia until it comes to a complete stop.
[0018] The basic structure of the winding device includes a support 7, a first base 5, and a second base 4. The first base 5 and the second base 4 are located on the left and right sides. Generally, the first base 5 and the second base 4 are designed as a rectangular structure, so that they have protruding corners facing the winding spindle 3.
[0019] The support 7 is provided with a baffle, which is composed of a dividing plate 13 and a dividing plate 14. When the winding spindle 2 is working, the baffle is unfolded. The opened baffle extends between the winding spindle 2 and the winding spindle 3, so it can effectively block the airflow formed when the winding spindle 2 rotates at high speed, thereby effectively preventing the yarn end of the full bobbin 10 from being entangled with the bobbin on the winding spindle 2. During the rotation of the winding turntable 1, the baffle is in a folded state, as shown in the attached figure. Figure 2 The support 7 is designed to have a protruding angle toward the winding spindle 3 .
[0020] After the full bobbin 10 is wound, the filaments are cut, leaving two filament ends, one of which remains loose on the full bobbin 10. The unconstrained filament end swings with a large amplitude as the full bobbin 10 continues to rotate due to inertia. During this swinging, the filament end collides with the aforementioned protruding corners, forming flocculent fibers. Furthermore, the filament end can easily get stuck in the gap between the split plates 13 and 14.
[0021] To this end, the winding device is provided with a guard plate portion, which includes a left guard plate portion and a right guard plate portion. The left guard plate portion is preferably arranged on the side of the support 7 facing the winding spindle 3 and is located on the left side of the winding spindle 3. The left guard plate portion includes a bending section 8.1, a bending section 8.3 and an intermediate section 8.2 connected between the bending section 8.1 and the bending section 8.2. The bending section 8.1 is bent toward the winding spindle 3 relative to the intermediate section 8.2, and the bending section 8.3 is bent toward the winding spindle 3 relative to the intermediate section 8.2. The left guard plate portion is installed basically in the vertical direction. The bending section 8.3 of the left guard plate portion is located between the protruding corner of the first base 5 facing the winding spindle 3 and the winding spindle 3, thereby preventing the filament end of the full roll 10 from colliding with the protruding corner. The middle section 8.2 or the bent section 8.1 of the left guard plate is located between the protruding corner of the support 7 facing the winding spindle 3 and the winding spindle 3, thereby preventing the filament end of the full bobbin 10 from colliding with the protruding corner. The bent section 8.1 of the left guard plate is located between the gap between the splitter plates 13 and 14 and the winding spindle, thereby preventing the filament end from being caught in the gap between the splitter plates 13 and 14.
[0022] The second base 4 is provided with a sub-base 6 and a lifting device 12. The lifting device 12 can be raised or lowered by a cylinder drive. When winding is in progress, the lifting device 12 is at the lowest position. Figure 1 When the threading operation is in progress, the lifting device 12 is at the highest position, as shown in the attached Figure 2 As shown. After being lifted, the lifting device 12 is used to assist the operator in the threading action. For this purpose, a hook-shaped wire guide element not shown in the accompanying drawings is installed on the top of the lifting device 12. When the operator performs manual threading, he holds a filament suction gun and hooks the filament on the hook-shaped wire guide element. During the swinging process, the filament end is also prone to collide with the sharp corners of the lifting device 12, causing flying fibers. Therefore, the right guard plate portion is provided between the lifting device 12 and the winding spindle 3.
[0023] The right guard plate is composed of a long curved section 9.2 and a short curved section 9.1, which are connected. The right end of the long curved section 9.2 is rotatably connected to the sub-base 6 via a hinge 11, and the left end is linked to the lifting device 12. When the threading operation begins, the lifting device 12 is lifted, and the left end of the long curved section 9.2 is lifted along with it. The long curved section 9.2 rotates around the hinge 11 until it moves to the adjacent Figure 2 After the threading operation is completed, the lifting device 12 is lowered until the right guard plate moves to the adjacent Figure 1 Position shown.
[0024] The linkage feature between the right guard plate and the lifting device 12 ensures that after the lifting device 12 is lowered, the right guard plate will inevitably be lowered together. Figure 2 If there is no such linkage, after the bobbin is wound to a certain size, the bobbin is bound to rub against the right guard plate, causing a safety hazard.
[0025] The linkage structure can be implemented as follows: the top end of the lifting device 12 contacts the lower surface of the right guard plate, and a pressure rod is provided on the top end of the lifting device 12, which is vertically separated from the upper surface of the right guard plate. When the lifting device 12 is raised, the lifting device 12 presses against the right guard plate to cause it to rotate clockwise; when the lifting device 12 is lowered, the pressure rod forces the right guard plate to rotate counterclockwise.
[0026] The surfaces and edges of the left guard plate portion and the right guard plate portion are designed to be smooth, so it is not easy to generate flying flowers when the filament end collides with them.
