Description

Technical Field

[0001] This application belongs to the technical field of glass fiber production equipment, specifically relating to a rotating and telescopic mechanism for expanding a winding cylinder. Background Technology

[0002] A brief introduction to the manufacturing process of glass fiber: After formulating the raw ore, it is melted into molten glass in a furnace, flows out through a porous platinum stencil, is coated with a sizing agent by a monofilament oiler, and is then drawn into ultrafine fibers by various high-speed rotating drawing equipment such as drawing machines. These fibers are either wound into direct untwisted rovings or into raw filament cakes. Several drawing and winding methods require the use of a winding bobbin to form the roving, which can be made of paper or Teflon. Currently, the drawing process has been automated with features such as automatic head loading, no-cut yarn ring loading, cutting of intermediate connecting yarns, and unloading robots, replacing manual labor. However, after the robot removes the roving, a manual person must still put the winding bobbin onto the drawing machine head for further drawing and winding. This is not only inefficient but also poses safety hazards due to human-machine collaboration, hindering the overall automated production process.

[0003] Please refer to the Chinese patent: An automatic loading and unloading mechanism for fiberglass drawing machines [Application Publication No.: CN115783899 A / Application No.: 202211622113.6]. This patent uses a servo motor, floating joint, and four-bar linkage to drive the extension and retraction of the support cylinder segments, but it suffers from technical problems such as a long transmission chain and low extension and retraction efficiency.

[0006] The solution provided in this application to resolve its technical problem is as follows:

[0007] A rotating telescopic mechanism for expanding a coiled bobbin includes a rotating disk, a rotating drive component, a guide disk, and several expanding bobbins. The expanding bobbins are movably mounted on the rotating disk. The rotating drive component is connected to the rotating disk via the guide disk. The rotating drive component can drive the expanding bobbins to rotate open or rotate to retract through the cooperation of the rotating disk and the guide disk.

[0008] The rotary drive component can drive the rotary disk to rotate relative to the guide disk, thereby driving the support cylinder expansion piece to rotate as well.

[0021] Beneficial technical effects:

[0022] This application sets expansion grooves and involute grooves on the rotating disk and guide disk respectively; it can achieve rapid rotational opening or rotational contraction of the support cylinder expansion plate by constraining the dual trajectory of the support cylinder expansion plate drive head in the micro-motion mode of the drive cylinder, which is beneficial to improving the support cylinder efficiency.

[0034] Please see Figure 1The expansion plate rotation and telescopic mechanism for expanding a wire bobbin disclosed in this application includes a rotating disk 10, a rotation drive component 20, a guide disk 30, a plurality of expansion plates 40, and a fixing frame 50.

[0035] The rotating disk 10 is provided with four telescopic grooves 110, which are centrally symmetrically distributed and extend radially. Each telescopic groove 110 has a limiting edge 120 at its edge.

[0036] The rotary drive component 20 is a rotary cylinder, which is connected to the rotary disk 10. The rotary cylinder can drive the rotary disk 10 to rotate to generate driving force.

[0037] The guide plate 30 is provided with four involute grooves 310. The four involute grooves 310 are centrally symmetrically distributed and extend in an arc shape from the part near the axis of the guide plate to the part near the edge of the axial plate.

[0038] The expansion sleeve 40 includes an expansion sleeve body 410, a drive head 420, and an expansion sleeve seat 430; the expansion sleeve body 410 and the expansion sleeve seat 430 are integrally formed or fixedly connected; the drive head 420 and the drive head 420 are integrally formed or fixedly connected; the expansion sleeve seat 430 is provided with a limiting mating edge 440.

[0039] The fixed frame 50 is provided with a rotating groove 510, and the rotating groove 510 is provided with a drive shaft hole.

[0040] The rotating disk 10 and the guide disk 30 are sequentially arranged in the rotating groove 510; the guide disk 30 is fixedly connected to the fixed frame 50. The rotating shaft of the rotary cylinder passes through the drive shaft hole and is connected to the rotating disk 10 for transmission. The rotary cylinder can drive the rotating disk 10 to rotate to generate the driving force for the expansion and contraction of the expansion plates.

[0041] The expansion sleeve 40 is movably set in the expansion groove 110 by the cooperation of the limiting edge 120 and the limiting mating edge 440, and the drive head 420 is simultaneously set in the expansion groove 110 and the involute groove 310.

[0042] When the rotating disk 10 rotates, it can drive the support tube expansion piece 40 to move together. When the support tube expansion piece 40 moves, it is constrained by the double trajectory formed by the expansion groove 110 and the involute groove 310. It rotates along the involute groove 310 while radially expanding and contracting within the expansion groove 110, thereby realizing rotational opening or rotational contraction.

[0043] Figure 2The diagrams show the expansion joints 40 in both their contracted and open states. In the contracted state, the drive head 420 of each expansion joint 40 is located on the involute 310 closest to the axis of the guide disk 30 (and simultaneously on the telescopic groove 110 on the rotating disk 10 closest to the axis of the rotating disk 10). In the open state, the drive head 420 of each expansion joint 40 is located on the involute 310 closest to the edge of the guide disk 30 (and simultaneously on the telescopic groove 110 on the rotating disk 10 closest to the edge of the rotating disk 10).

[0044] Thus, during the process of the expansion sleeve 40 changing from a contracted state to an open state, the rotating disk 10 rotates 90 degrees; conversely, it rotates 90 degrees in the opposite direction. That is, the expansion sleeve 40 can complete the conversion between its contracted and open states with slight movements of the rotating cylinder.

[0045] In one modified embodiment of this application, the expanding plate rotation and telescopic mechanism further includes a synchronization disk 60. The synchronization disk 60 has four drive grooves 610; these four drive grooves 610 are centrally symmetrically distributed and extend radially. The guide disk 30, synchronization disk 60, and rotating disk 10 are sequentially arranged within the rotating groove 510; the drive head 420 is simultaneously assembled within the involute groove 310, the telescopic groove 110, and the drive groove 610. The synchronization disk 60, positioned between the guide disk 30, the synchronization disk 60, and the rotating disk 10, helps to increase the stability and synchronicity of the expanding plate 40's rotational opening or contraction movements.

[0046] In one modified embodiment of this application, the support tube expansion piece 40 adopts an integrally formed structure, which is provided with an expansion piece body (corresponding to expansion piece body 410), an expansion piece seat (corresponding to expansion piece seat 430), and a driving part (corresponding to driving head 420); the edge of the expansion piece seat is provided with a limiting fit part (corresponding to limiting fit edge).

[0047] In one modified embodiment of this application, the expanding plate rotation and telescopic mechanism can also be rotated 180 degrees vertically to adjust the orientation of the expanding plate 40 and the winding bobbin on it. The expanding plate rotation and telescopic mechanism also includes a support base 70 and a flipping mechanism 80; the flipping mechanism 80 includes a flipping frame 810 and a flipping drive component 820. The flipping frame 810 is hinged to the support base 70 via a bearing and a rotating shaft, and the flipping drive component 820 is driveably connected to the flipping frame 810. The flipping drive component 810 can be a cylinder, a hydraulic cylinder, or a motor.

[0048] In one modified embodiment of this application, the expanding plate rotary telescopic mechanism further includes a support seat moving mechanism; the support seat moving mechanism is used to drive the support seat 710 to perform linear reciprocating motion. The support seat moving mechanism includes a support seat guide rail and a support seat drive mechanism. The support seat drive mechanism can drive the support seat 710 to perform reciprocating linear motion along the support seat guide rail. The support seat drive mechanism can be a commonly used power component such as a motor lead screw slide module, hydraulic cylinder, or pneumatic cylinder, and the support seat 710 can establish a slidable connection with the support seat guide rail through a guide rail pair. The structure and connection of the support seat moving mechanism are prior art and will not be described in detail here.

[0049] In one modified embodiment of this application, the expanding plate rotation and telescopic mechanism further includes a pusher mechanism; the pusher mechanism includes a pusher cylinder and a pusher component; the pusher cylinder is disposed on the rotating disk 10 and is drively connected to the pusher component.

[0050] The pusher mechanism is used to push the coiled yarn bobbin, which has been expanded into a circle, onto the head of the drawing machine. The pusher mechanism includes a pusher cylinder and a pusher assembly; the pusher cylinder is mounted on the rotary disk 10 and is driven to the pusher assembly. The pusher cylinder drives the pusher assembly to extend and retract along the length of the support plate to complete the pusher and reset actions; preferably, the pusher assembly's structure matches the end edge of the coiled yarn bobbin. The pusher mechanism is prior art and will not be described in detail here.

[0051] The technical solutions and effects of this application have been described in detail above with reference to the accompanying drawings and specific embodiments. It should be noted that those skilled in the art can develop other embodiments based on this. Any simple modifications and equivalent substitutions that do not depart from the innovative concept of this application are covered by this application and fall within the protection scope of this patent.
