Description

Technical Field

[0001] The utility model relates to the technical field of filament winding machines, in particular to a continuous unwinding and storage mechanism for filament winding machines. Background Art

[0002] Fiber film is a film formed by calendering a fiber textile material and a rubber compound. A filament winding machine is a key piece of equipment that wraps and coats the fiber film around a core mold to produce the desired fiber composite product. It is widely used in aviation, aerospace, building materials, petrochemicals, and other fields. With the increasing application of composite materials and the increasing performance requirements for their components, the demand for filament winding equipment has been increasing in recent years. Because fiber film has a certain degree of elasticity and softness, and some core mold processes require a relatively thin thickness of only 0.2mm, to prevent the film from sticking, breaking, and curling, and to ensure a smoother film, a layer of lining cloth is applied to the rubber compound when the fiber film is calendered and rolled. This means that the filament winding machine must also include a lining cloth recovery mechanism during the rubber compound unwinding process.

[0003] The utility model disclosed in the announcement number 202310107832.2 discloses a structure and method for centrifugal paper recovery and splicing of the unwinding feeding belt of the encapsulating machine, which provides a double-disc unwinding and splicing device. Its technical features are: the blue film is pulled out by the tension of the centrifugal paper winding mechanism, and the blue film at the unwinding end of the blue film is connected to the other disk by the pressure of the cylinder. This structure is used for surface protection and insulation isolation of the battery material; however, due to the difference between the characteristics of the blue film and the fiber film, the blue film has high tensile strength and is easy to stick, while the fiber film has the characteristics of rubber. Excessive tension during unwinding can easily break the ultra-thin film. In addition, the blue film in this patent is compressed and bonded while feeding normally, and there is no material storage structure. This structure is not suitable for the continuous, uninterrupted, and unbroken conveying requirements of the fiber winding machine during continuous winding of the fiber. Utility Model Content

[0034] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0035] Example 1

[0036] In a typical embodiment of the present invention, reference is made to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a continuous unwinding and storage mechanism for a filament winding machine includes a base 9, on which a first frame 1 and a second frame 5 are provided. The first frame 1 and the second frame 5 are adjacently arranged, and the second frame 5 is located on the right side of the first frame 1 ( Figure 1 The first frame 1 and the second frame 5 are fixed to the chassis 9 by screws.

[0037] The first frame 1 is equipped with an unwinding mechanism 2, a lining cloth recovery mechanism 3, a first guide wheel group 4, and a second guide wheel group 4A.

[0038] The second frame 5 , the material storage mechanism 6 , the fiber film bonding mechanism 7 , and the pressing wheel mechanism 8 are installed on the second frame 5 .

[0039] The first frame 1 is vertically arranged in a columnar shape. A pair of unwinding mechanisms 2 and a lining cloth recovery mechanism 3 are mounted on the upper and lower sides of the first frame 1, respectively, for unwinding and recovering the lining layer. Each set of unwinding mechanisms 2 is accompanied by a corresponding set of lining cloth recovery mechanisms 3. The lining cloth recovery mechanisms 3 are located on the right side of the first frame 1, at the unwinding end of the unwinding mechanisms 2. Also mounted on the right side of the first frame 1 are a first guide wheel assembly 4 and a second guide wheel assembly 4A, corresponding to the two pairs of unwinding mechanisms 2 and the lining cloth recovery mechanism 3, respectively.

[0040] The first guide wheel assembly 4 and the second guide wheel assembly 4A each comprise multiple guide wheels. These guide wheels are located outside and bypass the interlining cloth recovery mechanism 3. The first guide wheel assembly 4 and the second guide wheel assembly 4A are respectively used to transport the fiber film between the two trays. The first guide wheel assembly is used to transport the fiber film from the unwinding mechanism 2 located above the first frame 1, while the second guide wheel assembly 4A is used to transport the fiber film from the unwinding mechanism 2 located below the first frame 1, transporting the fiber film to the second frame 5.

[0041] like Figure 2 、 Figure 3 As shown, the two sets of unwinding mechanisms 2 include a fiber film material tray 2-1, an unwinding shaft 2-2, a bearing seat 2-3, a coupling 2-4, an unwinding servo motor 2-5 and an unwinding motor mounting seat 2-6.

[0042] by Figure 1 and Figure 2 Taking the perspective as an example, the unwinding motor mounting seat 2-6 is fixed to the rear side of the first frame 1, the unwinding servo motor 2-5 is fixed to the unwinding motor mounting seat 2-6 by screws, and the standard bearing seat 2-3 is installed and fixed on the left side of the first frame 1. The unwinding shaft 2-2 is supported by the bearing seat 2-3 and is connected to the output shaft of the unwinding servo motor 2-5 through the coupling 2-4. The fiber film material disc 2-1 is fixed to the end of the unwinding shaft 2-2 and is located on the front side of the first frame 1. The active unwinding operation of the fiber film is realized by the rotation of the unwinding servo motor 2-5 to ensure that the fiber film will not be broken during the unwinding process.

[0043] like Figure 2 、 Figure 3 As shown, the lining cloth recovery mechanism 3 includes a winding servo motor 3-4, a coupling 3-3, a bearing seat 3-2, a winding motor mounting seat 3-5 and a recovery shaft 3-1.

[0044] The front end of the recovery shaft 3-1 is arranged corresponding to the fiber film material disc 2-1, the winding servo motor 3-4 is fixed to the winding motor mounting seat 3-5 on the rear side of the first frame 1 by screws, and the bearing seat 3-2 is installed and fixed on the right side of the first frame 1. The recovery shaft 3-1 is supported by the bearing seat 3-2 and is connected to the output shaft of the winding servo motor 3-4 through the coupling 3-3. The winding operation of the lining cloth is realized by the rotation of the winding servo motor 3-4.

[0045] like Figure 1 、 Figure 2 、 Figure 3 As shown, the first guide wheel group 4 includes a support frame 4-1, a guide wheel 4-2, and a guide wheel shaft 4-3, and the second guide wheel group 4A includes a second support frame 4A-1, a guide wheel 4-2, and a guide wheel shaft 4-3. The first guide wheel group 4 and the second guide wheel group 4A have the same structure and are symmetrically arranged in the upper and lower parts.

[0046] The support frame 4-1 and the second support frame 4A-1 are respectively fixed to the right side of the first frame 1 by screws, and the guide wheel 4-2 is connected to the guide wheel shaft 4-3 through a bearing and is distributed on the support frame 4-1 and the second support frame 4A-1 through the guide wheel shaft 4-3. It is used to transmit the fiber rubber strips while ensuring that the rubber strips meet the position requirements required for subsequent pressing and bonding processes.

[0047] The guide wheel assembly of this embodiment is used to transport the unwound fiber film to the second frame 5, and at the same time the lining cloth recovery mechanism 3 recovers the lining cloth by rotating the recovery shaft 3-1.

[0048] The second frame 5 is equipped with a hopper mechanism 6, a fiber-film bonding mechanism 7, and a pinch roller mechanism 8, which are used for storing and unloading the film, as well as for bonding the spool head during reel changes. The fiber-film bonding mechanism 7 and pinch roller mechanism 8 are located on the top surface of the second frame 5, near one end of the first frame 1. The fiber-film bonding mechanism 7 is located between the first frame 1 and the pinch roller mechanism 8. The fiber-film moves through the fiber-film bonding mechanism 7 and the pinch roller mechanism 8, and then through the hopper mechanism 6.

[0049] like Figure 1 、 Figure 2 、 Figure 3 As shown, the pressing wheel mechanism 8 includes a cylinder seat 8-1, a pressing wheel cylinder 8-2, a bracket 8-3, a pressing wheel 8-4, a roller 8-5 and a roller shaft 8-6.

[0050] Cylinder base 8-1 is screwed to the top surface of the second frame 5. The pressure roller cylinder 8-2 is fixed to cylinder base 8-1 with its output end facing downward. Bracket 8-3 is mounted at the bottom end of the telescopic rod of pressure roller cylinder 8-2. Bracket 8-3 is U-shaped and mounts pressure roller 8-4. Roller 8-5 is connected to roller shaft 8-6 via a bearing. Roller shaft 8-6 is fixed to the second frame 5 and located below pressure roller 8-4.

[0051] Through the telescopic movement of the pressure wheel cylinder 8-2, the pressure wheel 8-4 is driven to move up and down to achieve the compression and loosening action with the roller 8-5, thereby realizing the operation of compacting the rubber strip when changing the roll and loosening the rubber strip after the rubber material is bonded and continuing to unwind.

[0052] like Figure 1 、 Figure 2 、 Figure 3 As shown, the fiber film bonding mechanism 7 includes a cylinder 7-1, a cylinder seat 7-2, an upper pressing plate 7-3 and a lower pressing plate 7-4.

[0053] The cylinder seat 7-2 is fixed to the second frame 5 by screws, and the cylinder 7-1 is installed on the cylinder seat 7-2 with the output end facing downward. The upper pressure plate 7-3 is installed at the front end of the telescopic rod of the cylinder 7-1, and the lower pressure plate 7-4 is fixed on the second frame 5 and is located correspondingly below the upper pressure plate 7-3. The telescopic movement of the cylinder 7-1 drives the upper pressure plate 7-3 to move up and down, so that the upper pressure plate 7-3 is close to or away from the lower pressure plate 7-4, thereby realizing the roll changing operation of pressing and bonding the head and tail ends of the two rolls of rubber material after manual gluing.

[0054] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the storage mechanism 6 includes a storage lifting frame 6-1, a lower roller 6-2, a bearing seat 6-3, a connecting plate 6-4, a roller servo motor 6-5, a roller reducer 6-6, a coupling 6-7, a drive motor 6-8, a drive reducer 6-9, a gear rack transmission mechanism 6-10 and an upper roller 6-11.

[0055] The second frame is an inverted U-shaped structure, consisting of a top plate and two uprights. A fiber film bonding mechanism 7 and a pressure roller mechanism 8 are mounted on the top surface of the top plate, while a material storage mechanism 6 is positioned between the two uprights. Rollers 8-5 are located on the front side of the top plate. Racks are located on the outer sides of the two uprights, and a material storage lift 6-1 is positioned transversely between the uprights. A rack-and-pinion transmission mechanism 6-10 is located at each end of the material storage lift 6-1. Specifically, a drive motor 6-8 drives a gear at its output end, which cooperates with the rack to enable the material storage lift 6-1 to rise and fall between the uprights.

[0056] The material storage lifting frame 6-1 is horizontally arranged between the columns, and a plurality of bearing seats 6-3 are arranged on the front side of the material storage lifting frame 6-1 along the length direction, and the lower roller 6-2 is connected to the bearing seat 6-3 through a bearing.

[0057] like Figure 4 As shown, the shaft end of the lower roller 6-2 is connected to the output shaft of a roller reducer 6-6 on the rear side of the second frame 5 via a coupling 6-7. The roller reducer 6-6 is fixed to a connecting plate 6-4, which is in turn fixed to the rear side of the material storage lifting frame 6-1. A roller servo motor 6-5 on the connecting plate 6-4 is connected to the roller reducer 6-6 to drive the shaft end of the lower roller 6-2. Driven by the roller servo motor 6-5, the lower roller 6-2 can be driven to rotate, achieving active feeding.

[0058] The driving motor 6-8 and the driving reducer 6-9 are respectively installed at both ends of the storage lifting frame 6-1. Under the drive of the driving motor 6-8 and the driving reducer 6-9, the gear rack transmission mechanism 6-10 transmits the transmission, and the storage lifting frame 6-1 and the lower roller 6-2 group installed on the lifting frame 6-1 perform lifting movements to complete the material discharge and storage operations.

[0059] The top of the second frame 5 and the front side of the top plate are provided with a plurality of upper rollers 6-11, and the upper rollers 6-11 are connected to the second frame 5 through the bearing seat 6-3. Figure 1 As shown, the upper roller 6-11 and the lower roller 6-2 are staggered. The upper roller reducer 6-6 is fixed to the rear side of the second frame 5. The shaft end of the upper roller 6-11 is also connected to the upper roller reducer 6-6 via a coupling 6-7. The upper roller 6-11 can also rotate under the drive of the upper roller servo motor to achieve active feeding. The roller is located on the side of the upper roller closest to the first frame. The upper pressure plate, the lower pressure plate, the roller, and the pressure wheel all extend to the front side of the second frame.

[0060] Furthermore, the matching speed parameter programs of all servo motors in each device provide program guarantee for the uninterrupted and continuous transmission of the entire fiber tape.

[0061] The working principle of this embodiment is as follows:

[0062] Two fiber film material trays 2-1 are mounted on the unwinding shaft 2-2, and the unwinding operation is started.

[0063] When unwinding starts, one of the fiber film discs 2-1 in the double-disc unwinding mechanism starts to actively unwind under the drive of the servo motor to prevent the fiber film from being broken.

[0064] At the same time, the lining cloth recovery mechanism 3 arranged opposite to the unwinding mechanism 2 starts to recover the lining cloth under the drive of the winding servo motor. The separated fiber film is transmitted in parallel to the fiber film bonding mechanism 7 and the pressure wheel mechanism 8 through the guide wheel group mechanism, and then enters the storage mechanism 6. The fiber strips are alternately transmitted between the upper and lower rollers in the storage mechanism 6.

[0065] At the beginning of transmission, by controlling the speed of the unwinding servo motor, the lining cloth recovery servo motor and the servo motors in the storage mechanism, the storage lifting frame in the storage mechanism moves downward to store material. When the rubber material of the currently unwound material tray is almost finished, the clamping cylinder in the pressure roller mechanism 8 drives the pressure roller to move downward, and presses the tail end of the fiber film of the currently unwound material tray, and at the same time reserves a section of rubber material to be spread flat on the lower pressure plate of the fiber film bonding mechanism 7. While the clamping cylinder in the pressure roller mechanism 8 presses the rubber material, the storage lifting frame 6-1 drives the lower roller on the lifting frame to move upward under the drive of the drive motor and the reducer, and at the same time continuously conveys the stored fiber tape to the winding mechanism for uninterrupted winding operation of the core mold.

[0066] While the storage mechanism moves upward to discharge material, a person needs to manually apply glue to the fiber film head remaining on the lower pressure plate 7-4, and then control another disk of glue to be unwound under the drive of its unwinding servo motor and the lining cloth recovery servo motor. The head end of the glue of this material disk is manually stacked on the tail end of the upper disk of glue that has been brushed with glue and is located on the lower pressure plate of the fiber film bonding mechanism. After that, the cylinder of the fiber film bonding mechanism drives the upper pressure plate to press downward to bond the two disks of glue together, and then the pressure wheel mechanism releases the pressure on the fiber film, replaces the new tape reel to continue discharging, and then controls the speed of each servo motor to make the storage lifting frame move downward to store material, thereby completing the reel change and cyclic uninterrupted discharging.

[0067] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
