Description
Technical Field
The utility model relates to the field of composite material production equipment, in particular to an expansion sleeve device for quickly disassembling and assembling a paper tube.
Background
As is well known, composite materials (prepregs) are both continuous unidirectional fibres or textile fibres. The unidirectional fiber and fabric fiber prepreg is collected in a curling mode, rolled and curled on a paper cylinder of 12 inches/10 inches/6 inches, and the paper cylinder is fixed on a rolling device of equipment.
The existing equipment adopts a 12-inch/10-inch/6-inch inflatable sleeve mode to perform rolling operation, after a paper tube is arranged at a designated position, compressed air is injected into the inflatable sleeve, an air bag inside the inflatable sleeve expands outwards after high-pressure air is injected, and an inflatable sleeve upper expansion key is ejected out to contact with the inner wall of the paper tube, so that the purpose of fixing the paper tube is achieved. Because the use of inflatable sleeves requires the use of high pressure air and there is no source of high pressure air in some locations, there is a need for an inflatable sleeve device that does not require compression.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides the paper tube quick assembling and disassembling expansion sleeve device, which can quickly assemble and disassemble the expansion sleeve without a paper tube of a high-pressure air source.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a fiber container quick assembly disassembly cover device that expands, is equipped with the equipment rack, characterized by, the rolling main shaft is installed in the equipment rack, installs two sets of fixed armful seats on the rolling main shaft, and one set of fixed armful seat is last to be installed fixed taper sleeve, and another set of fixed armful seat is last to be installed fixed bedplate, installs three sets of screw rod hooks on the fixed bedplate, and the screw rod hook passes through the nut and is fixed with fixed bedplate, installs the spring on the screw rod hook, removes the taper sleeve and installs on fixed bedplate to cooperate with the screw rod hook and make three sets of screw rod hooks pass and remove taper sleeve terminal surface, remove and install eccentric dead lever on the screw rod hook outside the taper sleeve terminal surface, the fiber container is installed in the middle of fixed taper sleeve and removal taper sleeve.
The utility model has the advantages of simple structure, easy operation and quick disassembly and assembly of the expansion sleeve without a paper tube of a high-pressure air source.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic structural view of the present invention.
Fig. 2 is a schematic view of a first installation state of the paper tube of the utility model.
FIG. 3 is a schematic view of a second paper tube installation state of the present invention.
In the figure, 1-a winding spindle, 2-a fixed holding seat, 3-a fixed taper sleeve, 4-a fixed seat plate, 5-a movable taper sleeve, 6-a screw hook, 7-an eccentric fixed rod, 8-a spring, 9-a nut, 10-a gasket and 11-a paper tube.
Detailed Description
In the figure, a winding main shaft 1 is arranged on an equipment frame, 2 sets of fixed clasping seats 2 are arranged on the winding main shaft 1, a fixed taper sleeve 3 is arranged on one set of the fixed clasping seats 2, and a fixed seat plate 4 is arranged on the other set of the fixed clasping seats 2. Install 3 sets of screw rod hooks 6 on the fixed bedplate 4, the screw rod hook 6 passes through nut 9 and is fixed firm with fixed bedplate 4, installs spring 8 and packing ring 10 on the screw rod hook 6. The movable taper sleeve 5 is arranged on the fixed seat plate 4 and is matched with the screw rod hook 6, so that 3 sets of screw rod hooks 6 penetrate through the end face of the movable taper sleeve 5. An eccentric fixing rod 7 is arranged on a screw rod hook 6 outside the end surface of the movable taper sleeve 5, and a paper tube 11 is arranged between the fixed taper sleeve 3 and the movable taper sleeve 5.
When the winding device is used, the fixed taper sleeve 3 is fixed at the position M1 of the winding main shaft 1 through the fixed clasping seat 2, and the fixed seat plate 4 is fixed at the position M2 of the winding main shaft 1 through the fixed clasping seat 2. The paper tube 11 passes through the fixed seat plate 4, one end of the paper tube is placed on the fixed taper sleeve 3, and the inner ring of the paper tube 11 is in contact with the conical surface circumference of the fixed taper sleeve 3. The movable cone sleeve 5 is arranged on the fixed seat plate 4 and penetrates through the screw hook 6, so that the conical surface of the movable cone sleeve is contacted with the circumference of the inner ring of the paper tube 11. The eccentric fixing rod 7 is overlapped with the screw rod hook 6 (as shown in fig. 2), the distance between the end surface of the movable taper sleeve 5 and the edge of the paper tube 11 is L, and the length of the spring 8 is L1. Three sets of eccentric fixing rods 7 are rotated 180 degrees (as shown in fig. 3) around the hook center (circle center) of the screw rod hook 6, and the eccentric amount of the eccentric fixing rods 7 is S, so that the movable taper sleeve 5 moves for 2S distance towards the paper tube 11 under the extrusion of the eccentric fixing rods 7, the process spring 8 is compressed to L1-2S length from the original L1 length, and the compression spring applies reverse thrust to the movable taper sleeve 5. The distance between the end face of the movable taper sleeve 5 and the edge of the paper tube 11 is L-2S, at the moment, the inner ring of the paper tube is extruded and outwards expanded by the conical surfaces of the fixed taper sleeve 3 and the movable taper sleeve 5 and is fixed with the conical surfaces of the fixed taper sleeve 3 and the movable taper sleeve 5 (the conical surfaces are provided with knurling patterns for increasing friction), at the moment, the paper tube 11 is fixed with the fixed taper sleeve 3 and the movable taper sleeve 5, and the paper tube 11 is fixed with the winding spindle 1.
When the winding spindle 1 is driven by the driving device to rotate, the paper roll 11 is driven by the driving device to perform winding operation.
After the winding operation is completed, the three sets of eccentric fixing rods 7 reversely rotate 180 degrees around the hook cores (circle centers) of the screw rod hooks 6, the extrusion force of the eccentric fixing rods 7 on the movable taper sleeve 5 disappears, the movable taper sleeve 5 is outwards popped out under the action of the thrust of the spring 8, the movable taper sleeve 5 is separated from the paper tube 11, the movable taper sleeve 5 can be taken out after the eccentric fixing rods 7 are taken out, then the paper tube 11 wound with materials can be pulled and taken down, and the blanking operation is completed.
