Description

Technical Field

[0001] This utility model relates to the field of spinning winding guide technology, specifically a winding guide device for high-speed spinning. Background Technology

[0002] Spinning guide structures typically refer to components used in the production of chemical fibers to guide and stretch a stream of molten or solution-state polymer. This structure is crucial for ensuring fiber uniformity, strength, and final product quality. Spinning guide systems can include components such as nozzles, cooling devices, and collecting rollers, which work together to achieve an efficient spinning process.

[0003] A search of the China Patent Network (authorization announcement number CN222455340U) revealed a winding and guiding device for high-speed spinning. By setting up a rotating frame, a rotating arm, a guide roller, and mounting bolts, it solved the problems of inconvenience in adjusting the position of the guide roller during operation and inconvenience in removing the guide roller from the entire guide device.

[0004] In this application, the rotating arm achieves its locking function through fastening bolts. However, the operation of fastening bolts must rely on manual assistance using special tools. During high-speed spinning, this manual operation method has significant drawbacks: First, the strong vibration and thermal expansion effects generated by high-speed operation can easily lead to thread wear or deformation, which in turn can cause the bolts to jam or become impossible to disassemble, resulting in equipment failure and maintenance difficulties. Therefore, a winding and guiding device for high-speed spinning is proposed. Utility Model Content

[0005] Based on this, the present invention aims to at least solve one of the technical problems existing in the prior art. To this end, a winding guide device for high-speed spinning is proposed, which can quickly achieve the locking effect of the rotating arm, thereby ensuring efficient and reliable operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a winding and guiding device for high-speed spinning, comprising a rotating frame, the rotating frame comprising two sets of rotating plates arranged side by side, each set of rotating plates having a rotating arm rotatably mounted on its outer wall, each set of rotating arms having a positioning roller rotatably mounted on one side of its side extending into the rotating plate, and a guiding roller being assembled between the two sets of positioning rollers.

[0007] A stroke groove is provided at the position where the rotating plate contacts the positioning roller. A constraint groove is provided on the lower inner wall of the stroke groove to constrain the positioning roller. A placement groove is provided on the top of the rotating plate. A positioning strip is installed in the placement groove. A pair of rollers for constraining the positioning roller are provided on both sides of the positioning strip.

[0008] As a preferred technical solution, the roller is provided with an outer frame that engages with the outer wall of the positioning strip, and an inner plate that is connected and fixed to the top of the roller is used inside the outer frame.

[0009] As a preferred technical solution, T-grooves are provided on both sides of the positioning strip at the positions where they contact the outer frame. The number of T-grooves is multiple and they are equidistantly distributed along the length of the positioning strip.

[0010] As a preferred technical solution, a notch is provided at the top of the rotating plate near the end, and a gate bar is connected to the notch by a torsion spring. The width of the gate bar corresponds to the size of the constraint groove.

[0011] As a preferred technical solution, a channel steel is provided below the rotating frame, and the two sets of rotating arms abut against the top external corner of the rotating arms.

[0012] As a preferred technical solution, a rotating shaft is provided between the two sets of rotating plates, and a fixing plate is sleeved on the outer wall of the rotating shaft.

[0013] As a preferred technical solution, the two ends of the guide roller are fixed between two sets of rotating arms with bolts, and the outer wall of the rotating arm is provided with threaded holes.

[0014] In summary, the present invention has the following main advantages:

[0015] This invention utilizes the structural design of stroke grooves and constraint grooves to enable the positioning roller to move smoothly along a predetermined path and reliably lock in a designated position. The cooperation between the positioning bar and the roller effectively constrains the movement range of the positioning roller and prevents it from dislodging. The brake bar automatically resets under the action of the torsion spring, providing additional constraint force and ensuring the closed state of the constraint groove. The entire device achieves a rapid self-locking function for the rotating arm, eliminating the need for manual tool assistance, reducing thread wear and jamming risks, and improving the stability and maintenance efficiency of the high-speed spinning process.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A winding and guiding device for high-speed spinning, such as Figures 1 to 6 As shown, it includes a rotating frame 100, which includes two sets of rotating plates 101 arranged side by side. Each set of rotating plates 101 has a rotating arm 120 rotatably mounted on the outer wall. Each set of rotating arms 120 has a positioning roller 121 extending into the rotating plate 101 on one side. A guide roller 110 is assembled between the two sets of positioning rollers 121.

[0027] A travel groove 102 is provided at the position where the rotating plate 101 contacts the positioning roller 121. A constraint groove 103 is provided on the lower inner wall of the travel groove 102 to constrain the positioning roller 121. A mounting groove 105 is provided on the top of the rotating plate 101. A positioning strip 150 is installed in the mounting groove 105. A pair of rollers 160 for constraining the positioning roller 121 are provided on both sides of the positioning strip 150.

[0028] Above the roller 160 is an outer frame 170 that engages with the outer wall of the positioning strip 150. Inside the outer frame 170 is an inner plate 171 that is connected and fixed to the top of the roller 160.

[0029] T-grooves 151 are provided on both sides of the positioning strip 150 at the positions where they contact the outer frame 170. There are multiple sets of T-grooves 151, which are equidistantly distributed along the length of the positioning strip 150.

[0030] It is worth noting that the outer frame 170 is T-shaped and matches the dimensions of the T-slot 151;

[0031] A notch 104 is provided at the top and near the end of the rotating plate 101. A gate bar 140 is connected to the notch 104 by a torsion spring. The width of the gate bar 140 corresponds to the size of the constraint groove 103.

[0032] The outer wall of the rotating plate 101 is provided with a handle 141 that can drive the brake bar 140 to rotate;

[0033] The upper inner wall of the travel groove 102 is provided with two sets of relief grooves 106 that communicate with the placement groove 105, and the roller 160 can penetrate into the placement groove 105 from the relief groove 106.

[0034] A channel steel 200 is provided below the rotating frame 100, and two sets of rotating arms 120 abut against the top corner of the rotating arm 120.

[0035] When it is necessary to adjust the position of the rotating arm 120 inside the travel groove 102, firstly, a rotational external force is applied to the rotating arm 120, which causes it to rotate upward around the center of the positioning roller 121, thereby gradually lifting the rotating arm 120 and completely disengaging it from the channel steel 200; then, a horizontal external force is applied to the side closer to the rotating frame 100, driving the positioning roller 121 to move smoothly along the horizontal track of the travel groove 102 and the constraint groove 103; during the movement, the positioning roller 121 will contact the roller 160. Upon contact, the roller 160 creates an obstruction to slow down the movement speed; simultaneously, the positioning roller 121 applies an upward compressive force to the roller 160, causing the inner plate 171 to be compressed and retracted into the outer frame 170. Once the positioning roller 121 has completely passed the area of ​​the roller 160, the inner plate 171 automatically returns to its initial position under the action of the internal mechanism; finally, the positioning roller 121 precisely stops at the gap between the two sets of rollers 160, forming a stable locking position, thereby effectively constraining the rotating arm 120 and ensuring its fixed position;

[0036] like Figure 6 As shown, the outer walls on both sides of the positioning strip 150 are provided with multiple T-slots 151. The T-slots 151 are designed to install rollers 160. Users can flexibly select the slot position according to actual needs, thereby accurately determining the number and layout of rollers to adapt to the requirements of different mechanical configurations.

[0037] The installation steps for the rotating arm 120 are as follows: First, place the positioning roller 121 directly on the top surface of the brake bar 140. Then, the operator needs to apply a vertically downward external force to the rotating arm 120 or related components. Under this external force, the brake bar 140 is driven to rotate downward around its pivot. The downward rotation of the brake bar 140 fully opens the notch 104 area, forming sufficient space. At this time, the positioning roller 121 can smoothly enter and fall into the internal structure of the constraint groove 103 and the travel groove 102, completing the installation and positioning. Conversely, during disassembly, the operator needs to manually apply a rotational external force to the handle 141. This rotational external force drives the brake bar 140 to rotate downward as well. As the brake bar 140 moves downward, the notch 104 that originally constrained the positioning roller 121 opens, thereby releasing the constraint on the positioning roller 121.

[0038] A rotating shaft 130 is provided between the two sets of rotating plates 101, and a fixing plate is sleeved on the outer wall of the rotating shaft 130.

[0039] It can be fixed to an external platform with the help of a fixing plate, so that the rotating frame 100 is in a stable state.

[0040] Please refer to this carefully. Figure 2 and Figure 3 The two ends of the guide roller 110 are fixed between the two sets of rotating arms 120 by bolts, and the outer wall of the rotating arm 120 is provided with threaded holes.

[0041] This facilitates quick disassembly and installation of the guide roller 110, effectively improving the convenience of equipment maintenance and work efficiency.
